Abstract Modern biology builds upon the historic exploration of the natural world. Recognizing the origin of a species’ name is one path to honor the historic exploration and description of the natural world and the indigenous peoples that lived closely with organisms prior to their description. While digitization of historic papers catalogued in databases such as the Biodiversity Heritage Library (BHL) allows for searching of the first use and origin of names, the rapid pace of taxonomic publishing can occlude a thorough search for etymologies. The etymological origin of the genus name Ameiva is one such case; while unattributed in multiple recent works, it is of Tupí language origin. The first description was in the Historiae Rerum Naturalium Brasiliae by George Marcgrave (1648). Ameiva was the name used by Marcgrave’s Amerindian hosts in 17th century Dutch Brazil, where local people spoke the now extinct language Tupí. The Tupí origin was not lost, however, until as recently as the 2000s. Herein, the pre- and post-Linnaean use of the name Ameiva is traced and when the name is attributed to the Tupí language and to Marcgrave through time it is noted. The opportunity to discover and/or recover etymological origins, especially names from extinct and indigenous languages, provides insight into the early Western sciences. Careful study of etymology by naturalists is consistent with the idea that science is an evolving process with many predecessors to appreciate. PMID:29674919

Bruni, Renato; Sacchetti, Gianni

2009-02-11

The increasing diffusion of herbal products is posing new questions: why are products so often different in their composition and efficacy? Which approach is more suitable to increase the biochemical productivity of medicinal plants with large-scale, low-cost solutions? Can the phytochemical profile of a medicinal plant be modulated in order to increase the accumulation of its most valuable constituents? Will polyphenol-rich medicinal crops ever be traded as commodities? Providing a proactive answer to such questions is an extremely hard task, due to the large number of variables involved: intraspecific chemodiversity, plant breeding, ontogenetic stage, post-harvest handling, biotic and abiotic factors, to name but a few. An ideal path in this direction should include the definition of optimum pre-harvesting and post-harvesting conditions and the availability of specific Good Agricultural Practices centered on secondary metabolism enhancement. The first steps to be taken are undoubtedly the evaluation and the organization of scattered data regarding the diverse factors involved in the optimization of medicinal plant cultivation, in order to provide an interdisciplinary overview of main possibilities, weaknesses and drawbacks. This review is intended to be a synopsis of the knowledge on this regard focused on Hypericum perforatum L. (Hypericaceae/Guttiferae) secondary metabolites of phenolic origin, with the aim to provide a reference and suggest an evolution towards the maximization of St. John's Wort bioactive constituents. Factors considered emerged not only from in-field agronomic results, but also from physiological, genetical, biotic, abiotic and phytochemical data that could be scaled up to the application level. To increase quality for final beneficiaries, growers' profits and ultimately transform phenolic-rich medicinal crops into commodities, the emerging trend suggests an integrated and synergic approach. Agronomy and genetics will need to develop their breeding strategies taking account of the suggestions of phytochemistry, biochemistry, pharmacognosy and pharmacology, without losing sight of the economic balance of the production.

Folk Etymology (In English and Elsewhere).

ERIC Educational Resources Information Center

Poruciuc, Adrian

Folk etymology is defined as a change in word or phrase form resulting from an incorrect popular idea of its origin or meaning. Irregular phonetic-semantic shifts are produced by inter-language borrowing or by intra-language passage from one period to another. These shifts are more common in periods when there are no, or few, normative factors…

Yuzhu (Polygonati Odorati Rhizoma), Kangdingyuzhu (Polygonati Prattii Rhizoma), and zhugenqiyuzhu (Disporopsis Fuscopictae Rhizoma) are of the same family, but of different genera. They have all often used in Chinese Materia Medica (CMM) as Polygonati Odorati Rhizoma in China market. Three species of CMM are confused. For better application, we need to identify these plants accurately. This study use pharmacognosy technique and GC-MS analysis, three species of CMM were authenticated. In macroscopic characteristics, the fruit of Polygonati Odorati Rhizoma is blue-black, while the other two are maroon and dark purple orderly. Nodes of Polygonati Odorati Rhizoma are upward and light uplift, about 1 cm spacing, while the other are not. As for microscopic characteristics, the cortex of Polygonati Odorati Rhizoma only occupies about 1/5 of the radius of the transverse section with inconspicuous endodermis, which is much smaller than others. The type of vascular bundles of Polygonati Odorati Rhizoma is closed collateral, but the other is amphivasal. Raphides of calcium oxalate are scattered, but Raphides of the other two are like brooms and neat rows. GC-MS analysis of essential oil could provide different characteristics to distinguish three species. Twenty-three compounds were identified from essential oil of Polygonati Odorati Rhizoma and the main components were n-hexadecanoic acid (49.45%), while n-hexadecanoic acid of the other two are 23.92% and 9.45%. The content of n-hexadecanoic is strongly different. This research was aimed to establish a method by pharmacognosy and GC-MS analysis to identify three CMM and for providing scientifical data to ensure accuracy of origin of three species. © 2014 Wiley Periodicals, Inc.

In Canada's Sydney Coalfield, specimens of the extinct Carboniferous seed fern Macroneuropteris macrophylla (Brongniart) invariably show preservation stages intermediate between compression and fossilized-cuticle, even concerning a single pinnule. In this interdisciplinary approach, we study a ca. 300 to 350 mm long fossilized-cuticle-preserved frond section of M. macrophylla (Brongniart) that represents about one third of the length of a frond that was originally 1 m long. Size and preservation allow us to study the phytochemistry of the cuticle biomacropolymers over the length of the frond to assess what impact, if any, results would have on Carboniferous palaeophytochemotaxonomy. For comparison, the phytochemistry of compressions with their extracted cuticles from the same species and the same sample locality is also investigated. We use solid- and liquid-state, semi-quantitative Fourier transform infrared spectroscopy (FTIR) for the chemical characterization of the frond.Based on our results, we infer an essentially uniform phytochemistry over the fossilized-cuticle frond, suggesting that only a single pinnule needs to be analyzed to get an overall phytochemical picture of the frond, which has been our long-time working hypothesis. We distinguish between phytochemistry and cutinization. The latter is much less pronounced above than below the frond dichotomy, and we suggest a palaeoecological cause, rather than differing pathways of organic matter transformation. Moreover, cuticles below and above the frond dichotomy have essentially the same epidermal pattern, but those from below have features that may have been an adaptation to prevent stomatal flooding during the tropical, rainy season.This study suggests that chemically the fossilized-cuticle is more similar to the compression than to the cuticle obtained from that compression of the same species which invites reevaluation of the classical compression concept. ?? 2010 Elsevier B.V.

Paediatrics: the etymology of a name.

PubMed

Pearn, John

2011-08-01

Within the history of paediatrics is the history of the name used to describe it. The etymology of the word 'paediatrics' dates from its first written use, recorded as 'pädiatrik' in the German literature and as 'paediatric', later 'pediatric' in the USA, both first in 1850. Professor Robley Dunglison (1788-1869), the British and American medical lexicographer, first defined 'paediatria' as 'the treatment of the diseases of children' in 1855. 'Pediatric medicine' was promoted as a specialty in the USA in 1880. The oldest monumental inscription defining the specialty of 'paediatrics' in the UK is to be found on a plaque added (in 1950) to the memorial to Dr George Armstrong (1719-1789), a founder of the specialty of paediatrics, in Castleton Cemetery, Scottish Borders, Roxburghshire. 'Paediatrics' and 'child health', with subtle semantic distinctions, had become well established in the English-speaking world by the middle of the 20th century. This paper presents an interpretative chronology of the etymology of the descriptors of the specialty that enjoins all who care for children.

Ancient Greek Terminology in Hepatopancreatobiliary Anatomy and Surgery.

PubMed

Papoulas, Michail; Douvetzemis, Stergios

2015-08-01

Most of the terminology in medicine originates from Greek or Latin, revealing the impact of the ancient Greeks on modern medicine. However, the literature on the etymology of Greek words used routinely in medical practice is sparse. We provide a short guide to the etymology and meaning of Greek words currently used in the field of hepatopancreatobiliary (HPB) anatomy and surgery. Focusing on HPB medical literature, the etymology and origin of Greek words including suffixes and prefixes are shown and analyzed. For example, anatomy (anatomia) is a Greek word derived from the prefix ana- (on, upon) and the suffix -tomy from the verb temno meaning to cut. Surgery, however, is not a Greek word. The corresponding Greek word is chirourgiki derived from cheir (hand) and ergon (action, work) meaning the action made by hands. Understanding the root of Greek terminology leads to an accurate, precise and comprehensive scientific medical language, reflecting the need for a universal medical language as a standardized means of communication within the health care sector.

2014-01-01

Convolvulus pluricaulis Choisy (C. pluricaulis) is a perennial herb that seems like morning glory. All parts of the herb are known to possess therapeutic benefits. The plant is used locally in Indian and Chinese medicine to cure various diseases. It is used in Ayurvedic formulation for chronic cough, sleeplessness, epilepsy, hallucinations, anxiety etc. Based on the comprehensive review of plant profile, pharmacognosy, phytochemistry, pharmacological and toxicological data on the C. pluricaulis, there will be more opportunities for the future research and development on the herb C. pluricaulis. Information on the C. pluricaulis was collected via electronic search (using Pub Med, SciFinder, Google Scholar and Web of Science) and library search for articles published in peer-reviewed journals. Furthermore, information also was obtained from some local books on ethnopharmacology. This paper covers the literature, primarily pharmacological, from 1985 to the end of 2012. The C. pluricaulis is an important indigenous medicine, which has a long medicinal application for liver disease, epileptic disease, microbial disease, cytotoxic and viral diseases, central nervous system (CNS) disease in Ayurvedic medicine, traditional Chinese medicine and other indigenous medical systems. The isolated metabolites and crude extract have exhibited a wide of in vitro and in vivo pharmacological effect, including CNS depression, anxiolytic, tranquillizing, antidepressant, antistress, neurodegenerative, antiamnesic, antioxidant, hypolipidemic, immunomodulatory, analgesic, antifungal, antibacterial, antidiabetic, antiulcer, anticatatonic, and cardiovascular activity. A chemical study of this plant was then initiated, which led to the isolation of carbohydrats, proteins, alkaloids, fatty acids, steroids, coumarins, flavanoids, and glycosides as active chemicals that bring about its biological effects. A series of pharmacognostical studies of this plant show that it is a herb, its stem and leaves are hairy, more over it has two types of stomata, anisocytic and paracytic. A herb, C. pluricaulis has emerged as a good source of the traditional medicine for the treatment of liver disease, epileptic disease, microbial disease, cytotoxic and viral diseases, and CNS disease. Pharmacological results have validated the use of this species in traditional medicine. All the parts of the herb are known to possess therapeutic benefits. Expansion of research materials would provide more opportunities for the discovery of new bioactive principles from C. pluricaulis. PMID:25182446

2015-11-01

In this review, the phytochemistry and pharmacology of two ornamental gingers, Hedychium coronarium (butterfly ginger) and Alpinia purpurata (red ginger), are updated, and their botany and uses are described. Flowers of H. coronarium are large, showy, white, yellow or white with a yellow centre and highly fragrant. Inflorescences of A. purpurata are erect spikes with attractive red or pink bracts. Phytochemical investigations on the rhizomes of H. coronarium generated research interest globally. This resulted in the isolation of 53 labdane-type diterpenes, with little work done on the leaves and flowers. Pharmacological properties of H. coronarium included antioxidant, antibacterial, antifungal, cytotoxic, chemopreventive, anti-allergic, larvicidal, anthelminthic, analgesic, anti-inflammatory, anti-urolithiatic, anti-angiogenic, neuro-pharmacological, fibrinogenolytic, coagulant and hepatoprotective activities. On the contrary, little is known on the phytochemistry of A. purpurata with pharmacological properties of antioxidant, antibacterial, larvicidal, cytotoxic and vasodilator activities reported in the leaves and rhizomes. There is much disparity in terms of research effort within and between these two ornamental gingers.

Information and communication technologies are widely used in healthcare. However, there is not still a unified taxonomy for them. The lack of understanding of this phenomenon implies theoretical and ethical issues. This paper attempts to find out the basis for a classification, starting from a new perspective: the structural elements are obtained from the etymologies of the lexicon commonly used, that is words like telemedicine, telehealth, telecare and telecure. This will promote a better understanding of communication technologies; at the same time, it will allow to draw some reflection about health, medicine and care, and their semantic and relational nature.

Aloysia citrodora Paláu (Lippia citriodora Kunth), commonly known as "lemon verbena" is a medicinal plant native to South America, North Africa, and South of Europe which is used by native people for several indications such as diarrhea, flatulence, insomnia, and rheumatism. Despite the wide biological activities of lemon verbena, there is no current review summarizing medicinal properties of the plant; thus, this paper aims to discuss current state of the art regarding the phytochemistry, pharmacology, and therapeutic applications of A. citrodora considering in vitro, in vivo, and clinical studies. Electronic databases including PubMed, Scifinder, Cochrane library, Scopus, and Science direct were searched with the scientific name of the plant and its synonyms, as well as the common name. All studies on the ethnobotany, phytochemistry, pharmacology, and clinical application of the plant until October 2017 were included in this review. Despite the few number of studies on the ethnopharmacology of the plant, A. citrodora is widely assessed regarding its phytochemistry and biological activities. Neral and geranial are the main ingredients of the essential oil; whereas verbascoside is the most significant component of the extract. Biological activities such as antioxidant, anxiolytic, neuroprotective, anticancer, anesthetic, antimicrobial, and sedative effects are proved in cell cultures, as well as animal studies. Several pharmacological activities have been reported for A. citrodora; however, the plant is not fully assessed regarding its safety and efficacy in human. Future well-designed human studies are essential to confirm the therapeutic benefits of this plant in clinical settings. Copyright © 2018 Elsevier B.V. All rights reserved.

Phytochemistry is one of the course in Chemistry Department's curriculum which discusses about biosynthetic path of secondary metabolite compound in a plant, classification of secondary metabolite compound, isolation technique, and identification analysis. This course is expected to be able to bridge the generations of a nation that has expertise in managing the natural resources of Indonesian plants. In this research, it was evaluated the implementation of case study learning method towards students' understanding on phytochemistry course. The learning processes were conducted in 2 cycles i.e. before and after midterm. The first seven themes of materials before midterm were learned with case study method and the next seven themes of materials were studied with the same method with the module-assisted. The results showed that there was enhancement of students' understanding in class D that were obtained from comparison of midterm and final test. Contrarily, the students of class C have no significant enhancement. In addition, it was predicted that understanding enhancement was strongly influenced by the life skills and the motivation of students especially the academic skills aspect.

Within the fields of medicine and sociology, the descriptor "profession" (along with its brethren: profession, professionalization, and professionalism) has had a rich etymological history, with terms taking on different meanings at different times-sometimes trespassing into shibboleth and jargon. This etymological journey has co-evolved with the career of David Mechanic to whom this issue of the Journal of Health Politics, Policy and Law is devoted. We exploit a provocative metaphor applied to Mechanic's work on the challenges facing medicine as a profession as a playful exegesis on what we call "profession" to excavate an ensconced and encrusted domain of health jargon operating at the tensive interface of society and modern medical work.

The genera Suaeda and Salsola are halophytic plants belong to the family Chenopodiaceae. Species of these genera have been extensively used in traditional medicines against many diseases due to their various bioactive compounds such as carotenoids, vitamins, sterol, phenolic compounds etc. The present research was carried out to establish detailed pharmacognosy of Suaeda fruticosa, Suaeda monoica, Salsola imbricata and Salsola tragus, which included macroscopy, microscopy, physico-chemical parameters and qualitative phytochemical screening of leaf samples extracted with methanol and chloroform. It was observed that macroscopic and microscopic characteristics were diagnostic features and can be used for distinction and identification of these closely related plant species. Phytochemically, these plant species are rich in constituents like anthraquinones, alkaloids, carbohydrates, cardiac glycosides, flavonoids, saponins, phenolic compounds and terpenoids. Physico-chemical parameters revealed that in all investigated plant species; methanol extractive values were higher than that of chloroform. Moreover, total ash values were found to be higher than other acid insoluble and water-soluble ash values, while a considerable amount of moisture was present in the species of both genera. On the basis of pharmacognosy, species of Suaeda were found to be more promising than Salsola. Present investigation will contribute towards establishment of pharmacognostic profile of these medicinally effective plants species.

This review provides up-to-date information about the botany, traditional uses, phytochemistry, pharmacology, toxicity and quality control of Trichosanthis Fructus and discusses the perspectives on future research and possible directions of this traditional Chinese Medicine and its origin plants. The information on Trichosanthes kirilowii Maxim. and Trichosanthes rosthornii Harms was collected from published scientific materials, including books; monographs on medicinal plants; pharmacopoeia and electronic databases such as SCI finder, PubMed, Web of Science, ACS, Science Direct, Wiley, Springer, Taylor, CNKI and Google Scholar. Approximately 162 compounds, including terpenoids, phytosterols, flavonoids, nitrogenous compounds and lignans, have been isolated and identified from Trichosanthes kirilowii Maxim. and Trichosanthes rosthornii Harms. Numerous studies have shown that the extracts and compounds isolated from these two plants exhibit pharmacological activities, including protection against myocardial ischaemia, calcium antagonist, endothelial cell protection, anti-hypoxic, anti-platelet aggregation, expectorant, anti-inflammatory, cytotoxic and antioxidant. Trichosanthis Fructus is an essential traditional Chinese medicine with pharmacological activities that mainly affect the cardiovascular system. This review summarises its botany, traditional uses, phytochemistry and pharmacology. Future research is needed to clarify the different uses of the seeds, pericarps and fruits. Quality control of investigations of the fruits should be improved, and the potential uses of the flesh, leaves and twigs should be further explored. Copyright © 2018 Elsevier B.V.

A comprehensive study on essential oil and different solvent extracts of Sideritis romana L. subsp. purpurea (Tal. ex Benth.) Heywood (Lamiaceae) from Montenegro is reported. The gas chromatography-mass spectrometry analysis of the essential oil revealed a total of 43 components with bicyclogermacrene (23.8%), germacrene D (8%), ( E )-caryophyllene (7.9%) and spathulenol (5.5%) as the major ones. Sesquiterpenoid group was found to be the most dominant one (64.8%), with 19.9% of the oxygenated forms. In the crude methanol extract of the investigated plant, obtained by Sohhlet exraction, the total phenol content was 14.7 ± 0.4 mg of GA/g, the total flavonoids were 0.29 ± 0.03% expressed as hyperoside percentage, whereas the total tannins content was 0.22 ± 0.04% expressed as pyrogallol percentage. For the antimicrobial activity determination, the following microorganisms have been used: methicillin-susceptible Staphylococcus aureus (MSSA (American Type Culture Collection (ATCC) 29213)) and methicillin-resistant S. aureus (MRSA (clinical strain)), Escherichia coli (ATCC 25922), carbapenem-susceptible Klebsiella pneumoniae (clinical strain), carbapenem-resistant K. pneumoniae (clinical strain) and Candida albicans (ATCC 14053). The essential oil showed high potency against MSSA and MRSA, both at high (~5 × 10⁵ CFU/mL) and low (~5 × 10³ CFU/mL) inoculum. With respect to MSSA, the minimal inhibitory concentration (MIC) value was 0.307 mg/mL, with bactericidal activity obtained at 0.615 mg/mL, while, in the case of MRSA, the MIC and minimal bactericidal concentration (MBC) values were 0.076 and 0.153 mg/mL, respectively. Regarding anti- Candida albicans activity, the MIC value was 2.46 mg/mL without reaching fungicidal activity. In addition to the observed essential oil efficacy, different solvent extracts were analyzed for their antimicrobial activity. Similarly to the essential oil, thehighest efficacy was observed against both MSSA and MRSA strains, at high and low inoculums, in the case of the 1,2-dichloroethane and methanol extracts. A potent fungicidal activity has been also found for the n -hexane and 1,2-dichloroethane extracts. It can be concluded that Sideritis romana L. subsp. purpurea (Tal. ex Benth.) Heywood provides a wide range of application in different fields such as phytochemistry, pharmacology, toxicology or pharmacognosy.

2014-01-01

Platycladus orientalis leaves (Cebaiye) have been used for thousands of years as traditional Chinese medicine (TCM). According to the theory of TCM, they are categorized as a blood-cooling and hematostatic herb. In clinical practice, they were usually prescribed with heat-clearing herbs to reinforce the efficacy of hemostasis. The review provides the up-to-date information from 1980 to present that is available on the botany, processing research, phytochemistry, pharmacology and toxicology of the leaves. The information is collected from scientific journals, books, theses and reports via library and electronic search (Google Scholar, Pubmed and CNKI). Through literature reports, we can find that the leaves show a wide spectrum of pharmacological activities, such as anti-inflammatory, antioxidant, antimicrobial, disinsection, anticancer, diuretic, hair growth-promoting, neuroprotective and antifibrotic activities. Diterpene and flavonoids would be active constituents in P. orientalis leaves. Many studies have provided evidence for various traditional uses. However, there is a great need for additional studies to elucidate the mechanism of blood-cooling and hematostatic activity of the leaves. Therefore, the present review on the botany, traditional uses, phytochemistry and toxicity has provided preliminary information for further studies of this herb.

The linguistic roots of Modern English anatomical terminology.

PubMed

Turmezei, Tom D

2012-11-01

Previous research focusing on Classical Latin and Greek roots has shown that understanding the etymology of English anatomical terms may be beneficial for students of human anatomy. However, not all anatomical terms are derived from Classical origins. This study aims to explore the linguistic roots of the Modern English terminology used in human gross anatomy. By reference to the Oxford English Dictionary, etymologies were determined for a lexicon of 798 Modern English gross anatomical terms from the 40(th) edition of Gray's Anatomy. Earliest traceable language of origin was determined for all 798 terms; language of acquisition was determined for 747 terms. Earliest traceable languages of origin were: Classical Latin (62%), Classical Greek (24%), Old English (7%), Post-Classical Latin (3%), and other (4%). Languages of acquisition were: Classical Latin (42%), Post-Classical Latin (29%), Old English (8%), Modern French (6%), Classical Greek (5%), Middle English (3%), and other (7%). While the roots of Modern English anatomical terminology mostly lie in Classical languages (accounting for the origin of 86% of terms), the anatomical lexicon of Modern English is actually much more diverse. Interesting and perhaps less familiar examples from these languages and the methods by which such terms have been created and absorbed are discussed. The author suggests that awareness of anatomical etymologies may enhance the enjoyment and understanding of human anatomy for students and teachers alike. Copyright © 2012 Wiley Periodicals, Inc.

[An essay about science and linguistics].

Cugini, P

2011-01-01

Both the methodology and epistemology of science provided the criteria by which the scientific research can describe and interpret data and results of its observational or experimental studies. When the scientist approaches the conclusive inference, it is mandatory to think that both the knowledge and truth imply the use of words semantically and etymologically (semiologically) appropriate, especially if neologisms are required. Lacking a vocabulary, there will be the need of popularizing the inference to the linguistics of the context to which the message is addressed. This could imply a discrepancy among science, knowledge, truth and linguistics, that can be defined "semiologic bias". To avoid this linguistic error, the scientist must feel the responsibility to provide the scientific community with the new words that are semantically and etymologically coherent with what it has been scientifically discovered.

Taxonomic etymology – in search of inspiration

Jóźwiak, Piotr; Rewicz, Tomasz; Pabis, Krzysztof

2015-01-01

Abstract We present a review of the etymology of zoological taxonomic names with emphasis on the most unusual examples. The names were divided into several categories, starting from the most common – given after morphological features – through inspiration from mythology, legends, and classic literature but also from fictional and nonfictional pop-culture characters (e.g., music, movies or cartoons), science, and politics. A separate category includes zoological names created using word-play and figures of speech such as tautonyms, acronyms, anagrams, and palindromes. Our intention was to give an overview of possibilities of how and where taxonomists can find the inspirations that will be consistent with the ICZN rules and generate more detail afterthought about the naming process itself, the meaningful character of naming, as well as the recognition and understanding of names.

The oleoresin of Copaifera trees has been widely used as a traditional medicine in Neotropical regions for thousands of years and remains a popular treatment for a variety of ailments. The copaiba resins are generally composed of a volatile oil made up largely of sesquiterpene hydrocarbons, such as β-caryophyllene, α-copaene, β-elemene, α-humulene, and germacrene D. In addition, the oleoresin is also made up of several biologically active diterpene acids, including copalic acid, kaurenoic acid, alepterolic acid, and polyalthic acid. This review presents a summary of the ecology and distribution of Copaifera species, the traditional uses, the biological activities, and the phytochemistry of copaiba oleoresins. In addition, several biomolecular targets relevant to the bioactivities have been implicated by molecular docking methods.

The present review is aimed at providing a comprehensive summary on the botany, utility, phytochemistry, pharmacology, and clinical trials of Morus alba (mulberry or sang shu). The mulberry foliage has remained the primary food for silkworms for centuries. Its leaves have also been used as animal feed for livestock and its fruits have been made into a variety of food products. With flavonoids as major constituents, mulberry leaves possess various biological activities, including antioxidant, antimicrobial, skin-whitening, cytotoxic, anti-diabetic, glucosidase inhibition, anti-hyperlipidemic, anti-atherosclerotic, anti-obesity, cardioprotective, and cognitive enhancement activities. Rich in anthocyanins and alkaloids, mulberry fruits have pharmacological properties, such as antioxidant, anti-diabetic, anti-atherosclerotic, anti-obesity, and hepatoprotective activities. The root bark of mulberry, containing flavonoids, alkaloids and stilbenoids, has antimicrobial, skin-whitening, cytotoxic, anti-inflammatory, and anti-hyperlipidemic properties. Other pharmacological properties of M. alba include anti-platelet, anxiolytic, anti-asthmatic, anthelmintic, antidepressant, cardioprotective, and immunomodulatory activities. Clinical trials on the efficiency of M. alba extracts in reducing blood glucose and cholesterol levels and enhancing cognitive ability have been conducted. The phytochemistry and pharmacology of the different parts of the mulberry tree confer its traditional and current uses as fodder, food, cosmetics, and medicine. Overall, M. alba is a multi-functional plant with promising medicinal properties. Copyright © 2016 China Pharmaceutical University. Published by Elsevier B.V. All rights reserved.

The genus Warburgia (Canellaceae) is represented by several medicinal trees found exclusively on the African continent. Traditionally, extracts and products produced from Warburgia species are regarded as important natural African antibiotics and have been used extensively as part of traditional healing practices for the treatment of fungal, bacterial and protozoal infections in both humans and animals. We here aim to collate and review the fragmented information on the ethnobotany, phytochemistry and biological activities of ethnomedicinally important Warburgia species and present recommendations for future research. Peer-reviewed articles using "Warburgia" as search term ("all fields") were retrieved from Scopus, ScienceDirect, SciFinder and Google Scholar with no specific time frame set for the search. In addition, various books were consulted that contained botanical and ethnopharmacological information. The ethnopharmacology, phytochemistry and biological activity of Warburgia are reviewed. Most of the biological activities are attributed to the drimane sesquiterpenoids, including polygodial, warburganal, muzigadial, mukaadial and ugandensial, flavonoids and miscellaneous compounds present in the various species. In addition to anti-infective properties, Warburgia extracts are also used to treat a wide range of ailments, including stomach aches, fever and headaches, which may also be a manifestation of infections. The need to record anecdotal evidence is emphasised and conservation efforts are highlighted to contribute to the protection and preservation of one of Africa's most coveted botanical resources.

An approach to educating our pharmaceutical students about Kampo medicine in the six-year system of undergraduate pharmacy education at Kyoto Pharmaceutical University is introduced, including the author's opinions. Curriculum revisions have been made in our university for students entering after 2012. In teaching Kampo medicine at present, a medical doctor and an on-site pharmacist share information difficult to give in a lecture with the teaching staff in my laboratory. For example, before the curriculum revision, we conferred with a pharmacist and a doctor in the course "Kampo Medicine A, B" for 4th year students, in which students were presented a basic knowledge of Kampo medicine, the application of important Kampo medicines, combinations of crude drugs, etc. Further, in our "Introduction to Kampo Medicine" for 6th year students, presented after they have practiced in hospitals and community pharmacies, we again lecture on the pharmacological characteristics of Kampo medicines, on "pattern (Sho)", and on evidence-based medicine (EBM) and research studies of important Kampo medicines. After our curriculum revision, "Kampo Medicine A, B" was rearranged into the courses "Kampo and Pharmacognosy" and "Clinical Kampo Medicine". "Kampo and Pharmacognosy" is now provided in the second semester of the 3rd year, and in this course we lecture on the basic knowledge of Kampo medicine. An advanced lecture will be given on "Clinical Kampo Medicine" in the 6th year. We are searching for the best way to interest students in Kampo medicine, and to counteract any misunderstandings about Kampo medicine.

The phytochemistry of species of the genus Piper has been studied extensively, including Piper solmsianum. However, no studies have addressed the phytochemistry of the sap content of Piper species. To evaluate the transferring of secondary compounds from the saps of P. solmsianum to the honeydew of Edessa meditabunda. The honeydew of E. meditabunda and saps of P. solmsianum were analysed by GC-MS, (1) H-NMR and LC-MS. The lignan (-)-grandisin and the phenylpropanoid (E)-isoelemicin were detected in both saps of P. solmsianum and honeydew of E. meditabunda. Analysis of honeydew secreted by the sap-sucking insect E. meditabunda indicated that (-)-grandisin and (E)-isoelemicin are absorbed from the phloem of Piper solmsianum.

Sauer, Hans; Krischke, Ulrike

2004-01-01

Roughly 1350 Old English plant names have come down to us; this is a relatively large number considering that the attested Old English vocabulary comprises ca. 24 000 words. The plant names are not only interesting for botanists, historians of medicine and many others, but also for philologists and linguists; among other aspects they can investigate their etymology, their morphology (including word-formation) and their meaning and motivation. Practically all Old English texts where plant names occur have been edited (including glosses and glossaries), the names have been listed in the Old English dictionaries, and some specific studies have been devoted to them. Nevertheless no comprehensive systematic analysis of their linguistic structure has been made. Ulrike Krischke is preparing such an analysis. A proper dictionary of the Old English plant names is also a desideratum, especially since the Old English dictionaries available and in progress normally do not deal with morphological and semantic aspects, and many do not provide etymological information. A plant-name dictionary concentrating on this information is being prepared by Hans Sauer and Ulrike Krischke. In our article here, we sketch the state of the art (ch. 1), we deal with some problems of the analysis of Old English plant names (ch. 2), e.g. the delimitation of the word-field plant names, the identification of the plants, errors and problematic spellings in the manuscripts. In ch. 3 we sketch the etymological structure according to chronological layers (Indo-European, Germanic, West-Germanic, Old English) as well as according to the distinction between native words and loan-words; in the latter category, we also mention loan-formations based on Latin models. In ch. 4 we survey the morphological aspects (simplex vs. complex words); among the complex nouns, compounds are by far the largest group (and among those, the noun + noun compounds), but there are also a few suffix formations. We also briefly present some morphological peculiarities, e.g. formations with blocked (unique) morphemes, the question of homonyms, cases of obscuration and of popular etymology. In ch. 5 we outline semantic structures, and in ch. 6, we introduce the structure of the proposed dictionary of the Old English plant names, also providing several specimen entries.

Towards a formal genealogical classification of the Lezgian languages (North Caucasus): testing various phylogenetic methods on lexical data.

A lexicostatistical classification is proposed for 20 languages and dialects of the Lezgian group of the North Caucasian family, based on meticulously compiled 110-item wordlists, published as part of the Global Lexicostatistical Database project. The lexical data have been subsequently analyzed with the aid of the principal phylogenetic methods, both distance-based and character-based: Starling neighbor joining (StarlingNJ), Neighbor joining (NJ), Unweighted pair group method with arithmetic mean (UPGMA), Bayesian Markov chain Monte Carlo (MCMC), Unweighted maximum parsimony (UMP). Cognation indexes within the input matrix were marked by two different algorithms: traditional etymological approach and phonetic similarity, i.e., the automatic method of consonant classes (Levenshtein distances). Due to certain reasons (first of all, high lexicographic quality of the wordlists and a consensus about the Lezgian phylogeny among Caucasologists), the Lezgian database is a perfect testing area for appraisal of phylogenetic methods. For the etymology-based input matrix, all the phylogenetic methods, with the possible exception of UMP, have yielded trees that are sufficiently compatible with each other to generate a consensus phylogenetic tree of the Lezgian lects. The obtained consensus tree agrees with the traditional expert classification as well as some of the previously proposed formal classifications of this linguistic group. Contrary to theoretical expectations, the UMP method has suggested the least plausible tree of all. In the case of the phonetic similarity-based input matrix, the distance-based methods (StarlingNJ, NJ, UPGMA) have produced the trees that are rather close to the consensus etymology-based tree and the traditional expert classification, whereas the character-based methods (Bayesian MCMC, UMP) have yielded less likely topologies.

2017-01-01

Radix Bupleuri (Chaihu) has been used as a traditional medicine for more than 2000 years in China, Japan, Korea, and other Asian countries. Phytochemical studies demonstrated that this plant contains essential oils, triterpenoid saponins, polyacetylenes, flavonoids, lignans, fatty acids, and sterols. Crude extracts and pure compounds isolated from Radix Bupleuri exhibited various biological activities, such as anti-inflammatory, anticancer, antipyretic, antimicrobial, antiviral, hepatoprotective, neuroprotective, and immunomodulatory effects. However, Radix Bupleuri could also lead to hepatotoxicity, particularly in high doses and with long-term use. Pharmacokinetic studies have demonstrated that the major bioactive compounds (saikosaponins a, b 2 , c, and d) were absorbed rapidly in rats after oral administration of the extract of Radix Bupleuri . This review aims to comprehensively summarize the traditional uses, botany, phytochemistry, pharmacology, toxicology, and pharmacokinetics of Radix Bupleuri reported to date with an emphasis on its biological properties and mechanisms of action.

Paluzzi, Alessandro; Fernandez-Miranda, Juan; Torrenti, Matthew; Gardner, Paul

2012-11-01

Researching the origin of the terms that we use to identify neuroanatomical structures is a helpful and fascinating exercise. It can provide neuroscientists with a better insight and understanding of the macroscopic anatomy of the cranium and its contents. It can also help the novice to this discipline to become acquainted with structures whose three dimensional anatomy is often difficult to appreciate. The purpose of this article was to investigate the etymology of some of the terms referring to the macroscopic anatomical structures of the skull and the intracranial cavity. We observed how each name unravels an interesting story, sometimes linked to mythological creatures, other times to the shape of animals or objects and tools of everyday life. We conclude that even without a deep knowledge of the Greek, Latin, or Arabic language, learning who described a particular structure and how they decided to name it, makes the study of neuroanatomy more complete and fulfilling.

PubMed

Saleh-E-In, Md Moshfekus; Van Staden, Johannes

2018-06-28

Arctotis arctotoides (Asteraceae) is part of the genus Arctotis. Arctotis is an African genus of approximately 70 species that occur widely in the African continent with diverse medicinal values. This plant is used for the treatment of indigestion and catarrh of the stomach, epilepsy, topical wounds and skin disorders among the ethnic groups in South Africa and reported to have a wide spectrum of pharmacological properties. The aim of the present review is to appraise the botany, traditional uses, phytochemistry, pharmacological potential, analytical methods and safety issues of A. arctotoides. Additionally, this review will help to fill the existing gaps in knowledge and highlight further research prospects in the field of phytochemistry and pharmacology. Information on A. arctotoides was collected from various resources, including books on African medicinal herbs and Zulu medicinal plants, theses, reports and the internet databases such as SciFinder, Google Scholar, Pubmed, Scopus, Web of Science, and Mendeley by using a combination of various meaningful keywords. This review surveys the available literature of the species from 1962 to April 2017. In vitro and in vivo studies of the medicinal properties of A. arctotoides were reviewed. The main isolated and identified compounds were reported as sesquiterpenes, farnesol derivatives, germacranolide, guaianolides and some steroids, of which, nine were reported as antimicrobial. Monoterpenoids and sesquiterpenoids were the predominant essential oil compound classes of the leaves, flowers, stems and roots. The present review revealed potential pharmacological properties such as anti-oxidant, antibacterial, antifungal and anticancer activities of plant extracts as well as isolated compounds. Moreover, the review reports the safety profile (toxicity) of the crude extracts that had been screened on brine shrimps, rats and human cell lines. The present review has focused on the phytochemistry, botany, ethnopharmacology, biological activities and toxicological information of A. arctotoides. On the basis of reported data, A. arctotoides has emerged as a good source of natural medicine for the treatment of microbial infections, skin diseases, anti-inflammatory and anticancer agents and also provides new insights for further isolation of new bioactive compounds, especially the discovery of antimicrobial, anti-inflammatory and anticancer novel therapeutic lead drug molecules. Additionally, intensive investigations regarding pharmacological properties, safety assessment and efficacy with their mechanism of action could be future research interests before starting clinical trials for medicinal practices.

2010-06-01

With a realistic threat against biodiversity in rain forests and in the sea, a sustainable use of natural products is becoming more and more important. Basic research directed against different organisms in Nature could reveal unexpected insights into fundamental biological mechanisms but also new pharmaceutical or biotechnological possibilities of more immediate use. Many different strategies have been used prospecting the biodiversity of Earth in the search for novel structure-activity relationships, which has resulted in important discoveries in drug development. However, we believe that the development of multidisciplinary incentives will be necessary for a future successful exploration of Nature. With this aim, one way would be a modernization and renewal of a venerable proven interdisciplinary science, Pharmacognosy, which represents an integrated way of studying biological systems. This has been demonstrated based on an explanatory model where the different parts of the model are explained by our ongoing research. Anti-inflammatory natural products have been discovered based on ethnopharmacological observations, marine sponges in cold water have resulted in substances with ecological impact, combinatory strategy of ecology and chemistry has revealed new insights into the biodiversity of fungi, in depth studies of cyclic peptides (cyclotides) has created new possibilities for engineering of bioactive peptides, development of new strategies using phylogeny and chemography has resulted in new possibilities for navigating chemical and biological space, and using bioinformatic tools for understanding of lateral gene transfer could provide potential drug targets. A multidisciplinary subject like Pharmacognosy, one of several scientific disciplines bridging biology and chemistry with medicine, has a strategic position for studies of complex scientific questions based on observations in Nature. Furthermore, natural product research based on intriguing scientific questions in Nature can be of value to increase the attraction for young students in modern life science.

Rheum australe D. Don (Polygonaceae) has been commonly used in traditional medicine for a wide range of ailments related to the circulatory, digestive, endocrine, respiratory and skeletal systems as well as to infectious diseases. To provide the up-to-date information that is available on the botany, traditional uses, phytochemistry, pharmacology and toxicology of Rheum australe. Additionally, to highlight the possible uses of this species to treat different diseases and to provide a basis for future research. The present review covers the literature available from 1980 to 2011. The information was collected from scientific journals, books, theses and reports via a library and electronic search (Google Scholar, Web of Science and ScienceDirect). Ethnomedical uses of Rheum australe have been recorded from China, India, Nepal and Pakistan for 57 different types of ailments. The phytochemical studies have shown the presence of many secondary metabolites belonging to anthraquinones, stilbenes, anthrones, oxantrone ethers and esters, chromones, flavonoids, carbohydrate, lignans, phenols and sterols. Crude extracts and isolated compounds from Rheum australe show a wide spectrum of pharmacological activities, such as antidiabetic, anti-inflammatory, antifungal, antimicrobial, antioxidant, anticancer, hepatoprotective and immune-enhancing activities, as well as a usefulness for improving renal function. Rheum australe has been widely used source of medicine for years without any adverse effects. Many studies have provided evidence for various traditional uses. However, there is a need for additional studies of the isolated compounds to validate the traditional uses in human models. The present review on the botany, traditional uses, phytochemistry and toxicity has provided preliminary information for further studies and commercial exploitations of the plant.

Traditional system of medicine consists of large number of plants with various medicinal and pharmacological importances. This article provides a comprehensive review of the complete profile of an important mangrove plant Excoecaria agallocha L. ( Euphorbiaceae ) and elaborately describing the ethnobotany, phytochemistry, and pharmacological properties. It is used traditionally in the treatment of various diseases such as epilepsy, ulcers, leprosy, rheumatism, and paralysis. The latex obtained from the bark is poisonous in nature and may cause temporary blindness, thus it is also known as the blind-your-eye mangrove plant. Many phytoconstituents were isolated from the plant, which were mainly diterpenoids, triterpenoids, flavonoids, sterols, and few other compounds. The plant also showed many pharmacological activities such as antioxidant, antimicrobial, anti-inflammatory, analgesic, antiulcer, anticancer, antireverse transcriptase, antihistamine-release, antifilarial, DNA damage protective, antidiabetic, and antitumor protecting activities. Hence, this review could help guide researchers anticipating to undertake further investigations in these directions.

Plants provide a rich source of lead compounds for a variety of diseases. A novel approach combining phytochemistry and chemotaxis assays was developed and used to identify and study the mechanisms of action of the active compounds in F. japonica, a medicinal herb traditionally used to treat inflammation. Based on a bioactivity-guided purification strategy, two anthranoids, emodin and physcion, were identified from F. japonica. Spectroscopic techniques were used to characterize its crude extract, fractions and phytochemicals. The crude extract, chloroform fraction, and anthranoids of F. japonica significantly inhibited CXCR4-mediated chemotaxis. Mechanistic studies showed that emodin and physcion inhibited chemotaxis via inactivating the MEK/ERK pathway. Moreover, the crude extract and emodin could prevent or treat type 1 diabetes in non-obese diabetic (NOD) mice. This study illustrates the applicability of a combinational approach for the study of anti-inflammatory medicine and shows the potential of F. japonica and its anthranoids for anti-inflammatory therapy.

Abd Rani, Nur Zahirah; Husain, Khairana; Kumolosasi, Endang

2018-01-01

Moringa is a genus of medicinal plants that has been used traditionally to cure wounds and various diseases such as colds and diabetes. In addition, the genus is also consumed as a source of nutrients and widely used for purifying water. The genus consists of 13 species that have been widely cultivated throughout Asia and Africa for their multiple uses. The purpose of this review is to provide updated and categorized information on the traditional uses, phytochemistry, biological activities, and toxicological research of Moringa species in order to explore their therapeutic potential and evaluate future research opportunities. The literature reviewed for this paper was obtained from PubMed, ScienceDirect, and Google Scholar journal papers published from 1983 to March 2017. Moringa species are well-known for their antioxidant, anti-inflammatory, anticancer, and antihyperglycemic activities. Most of their biological activity is caused by their high content of flavonoids, glucosides, and glucosinolates. By documenting the traditional uses and biological activities of Moringa species, we hope to support new research on these plants, especially on those species whose biological properties have not been studied to date.

2018-06-28

Tithonia diversifolia (TD) is widely valued in several cultures for its medicinal properties. A comprehensive review of the current understanding of this plant species is required due to emerging concerns over its efficacy, toxicity and allergenic potential. We critically summarized the current evidence on the botany, traditional use, phytochemistry, pharmacology and safety of TD, with the view to provide perspectives for developing more attractive pharmaceuticals of plant origin, but also to lay a new foundation for further investigations on this plant. A preliminary consultation of search engines such as Web of Science, PubMed, ScienceDirect and other published/unpublished resources provided an overview of extant literature on TD. Then, we meticulously screened all titles, abstracts and full-texts to establish consistency in the application of inclusion criteria. Studies were considered for inclusion if they dealt with taxonomy, global distribution, local and traditional knowledge, phytochemistry, toxicity and biological effects. 1856 articles were retrieved among which 168 were revised and included. Several studies conducted on cell lines and animals provided supporting evidence for some ethnomedicinal claims of extracts from TD. Short-term use of Tithonia extracts were effective and well-tolerated in animals when taken at lower doses. Both the toxic and therapeutic effects were attributed to bioactive principles naturally occurring in this species including sesquiterpene lactones, chlorogenic acid and flavonoids. T. diversifolia is a valuable source of bioactive compounds with significant therapeutic implications and favourable safety index. However, more rigorously designed investigations are needed to recommend the whole plant or its active ingredients as a medication, and should focus on understanding the multi-target network pharmacology of the plant, clarifying the effective doses as well as identifying the potential interactions with prescribed drugs or other chemicals.

The genus Psiadia Jacq. ex. Willd. belongs to the Asteraceae family and includes more than 60 species. This genus grows in tropical and subtropical regions, being especially well represented in Madagascar and the Mascarene Islands (La Réunion, Mauritius and Rodrigues). Several Psiadia species have been used traditionally for their medicinal properties in Africa and the Mascarene Islands. Based on traditional knowledge, various phytochemical and pharmacological studies have been conducted. However there are no recent papers that provide an overview of the medicinal potential of Psiadia species. Therefore, the aim of this review is to provide a comprehensive summary of the botany, phytochemistry and pharmacology of Psiadia and to highlight the gaps in our knowledge for future research opportunities. The available information on traditional uses, phytochemistry and biological activities of the genus Psiadia was collected from scientific databases through a search using the keyword 'Psiadia' in 'Google Scholar', 'Pubmed', 'Sciencedirect', 'SpringerLink', 'Web of Science', 'Wiley' and 'Scifinder'. Additionally, published books and unpublished Ph.D. and MSc. dissertations were consulted for botanical information and chemical composition. Historically, species of the genus Psiadia have been used to treat a wide range of ailments including abdominal pains, colds, fevers, bronchitis, asthma, rheumatoid arthritis, skin infections and liver disorders among others. Phytochemical works led to the isolation of flavonoids, phenylpropanoids, coumarins and terpenoids. Furthermore, phytochemical compositions of the essential oils of some species have been evaluated. Crude extracts, essential oils and isolated molecules showed in vitro pharmacological activities, such as antimicrobial, anti-viral, anti-inflammatory, antiplasmodial and antileishmanial activities. Crude extracts of Psiadia dentata and Psiadia arguta have specifically been found to be potentially useful for inhibition of growth of Plasmodium falciparum. However, pharmacological data on this particular genus is quite limited. Further research is necessary to determine the active compounds and the underlying mechanisms.

Snake venoms: A brief treatise on etymology, origins of terminology, and definitions.

PubMed

Weinstein, Scott A

2015-09-01

The ancient perceptions of "venomous" and "poisonous snakes", as well as the Indo-European (IE) etymological origins of the term "venom" specifically associated with snakes are considered. Although several ancient cultures perceived snakes as symbols of fecundity and renewal, concurrent beliefs also associated venomous snakes with undesirable human characteristics or as portending non-propitious events. The respective IE roots of the terms "venom" and "poison", "wen" and "poi" refer to desire or the act of ingesting liquids. The origin of the term, "venom", is associated with polytheistic cults that emphasized attainment of desires sometimes assisted by "love potions", a term later interpolated with the word, "poison". Specific interpretation of the term, venom, has varied since its first probable use in the mid-Thirteenth Century. The definition of snake venom has long been contended, and interpretations have often reflected emphasis on the pharmacological or experimental toxicity of medically relevant snake venoms with less regard for the basic biological bases of these venoms, as well as those from snakes with no known medical significance. Several definitions of "snake venom" and their defining criteria are reviewed, and critical consideration is given to traditional criteria that might facilitate the future establishment of a biologically accurate definition.

Carriers for the Tunable Release of Therapeutics: Etymological Classification and Examples

PubMed Central

Uskoković, Vuk; Ghosh, Shreya

2016-01-01

Introduction Physiological processes at the molecular level take place at precise spatiotemporal scales, which vary from tissue to tissue and from one patient to another, implying the need for the carriers that enable tunable release of therapeutics. Areas Covered Classification of all drug release to intrinsic and extrinsic is proposed, followed by the etymological clarification of the term “tunable” and its distinction from the term “tailorable”. Tunability is defined as analogous to tuning a guitar string or a radio receiver to the right frequency using a single knob. It implies changing a structural parameter along a continuous quantitative scale and correlating it numerically with the release kinetics. Examples of tunable, tailorable and environmentally responsive carriers are given, along with the parameters used to achieve these levels of control. Expert Opinion Interdependence of multiple variables defining the carrier microstructure obstructs the attempts to elucidate parameters that allow for the independent tuning of release kinetics. Learning from the tunability of nanostructured materials and superstructured metamaterials can be a fruitful source of inspiration in the quest for the new generation of tunable release carriers. The greater intersection of traditional materials sciences and pharmacokinetic perspectives could foster the development of more sophisticated mechanisms for tunable release. PMID:27322661

2013-01-01

Spilanthes spp. are popular, over-the-counter remedies; they are sold over the internet under various names and are widely used in traditional medicine in various cultures. This review will summarize the important reports on the ethnopharmacology, botany, phytochemistry, and pharmacological properties as described in the literature from recent years (1920 to 2013). Spilanthes spp. are used for more than 60 types of disorders. They are reported to contain a number of biologically active phytochemicals, although a large number of ethnopharmacological uses have been documented; only a few of these species have been investigated for their chemical and biological activities. The studies are carried out mainly on Spilanthes extracts and a few metabolites substantiate the uses of these plants in traditional medicine. Well-conducted pharmacological studies are still needed for several traditional indications, and the mechanisms of action by which the plant extracts and the active compounds exert their pharmacological effects remain to be studied. They are predominantly used as extracts in personal care products, traditional medicines, and the pharmaceutical and culinary areas. Suggestions are made regarding some of the possible mechanisms of action as to how the known compounds may exert their biological activity. PMID:24454346

Morinda citrifolia (Noni) fruit--phytochemistry, pharmacology, safety.

PubMed

Potterat, Olivier; Hamburger, Matthias

2007-03-01

Products derived from Noni fruit (Morinda citrifolia) have been commercialised in the USA since the 1990s and are increasingly distributed all over the world. A large number of beneficial effects have been claimed for Noni. Fruit juice of Noni has been approved as a Novel Food by the European Commission in 2003. This article reviews current knowledge on the phytochemistry, pharmacology, safety aspects of Noni fruit and Noni-derived products, and health-related claims and benefits. The knowledge on the chemical composition of Noni fruit has considerably increased over recent years. A number of in vitro and, to a certain extent, in vivo studies demonstrate a range of potentially beneficial effects. However, clinical data are essentially lacking. To what extent the findings from experimental pharmacological studies are of potential clinical relevance is not clear at present. Based on a toxicological assessment, Noni juice was considered as safe. Due to recent reports of cases of hepatotoxicity, the safety issue has been re-examined in Europe. While the European Food Safety Authority sees no link between adverse effects on liver and consumption of Noni juice, a continuing monitoring of the situation is desirable and some vigilance advised.

Melissa officinalis L. is a medicinal plant that has long been used in different ethno-medical systems especially in the European Traditional Medicine and the Iranian Traditional Medicine for the treatment of several diseases. It is also widely used as a vegetable and to add flavor to dishes This review aimed to provide a summary on the botanical characterization, traditional uses, phytochemistry, pharmacological activities, pharmacokinetics and toxicity of M. officinalis, and discusses research gaps and future opportunities for investigations on this plant. We extensively reviewed major unpublished old texts, and published and electronic literature on traditional medicines of different regions of the world to find traditional uses of M. officinalis. Electronic databases including Web of Science, PubMed, ScienceDirect, Google Scholar and Scopus were searched to find articles (published between 1956 and 2015) on pharmacology and phytochemistry of M. officinalis. Traditional uses of M. officinalis have been recorded mostly in European countries, Mediterranean region and Middle East countries. Phytochemical investigations revealed that this plant contains volatile compounds, triterpenoids, phenolic acids and flavonoids. Crude extracts and pure compounds isolated from M. officinalis exhibited numerous pharmacological effects, from which only anxiolytic, antiviral and antispasmodic activities of this plant as well as its effects on mood, cognition and memory have been shown in clinical trials. AChE inhibitory activity, stimulation of the acetylcholine and GABAA receptors, as well as inhibition of matrix metallo proteinase-2 are the main mechanisms proposed for the widely discussed neurological effects of this plant. Modern pharmacological studies have now validated many traditional uses of M. officinalis. The data reviewed here revealed that M. officinalis is a potential source for the treatment of a wide range of diseases especially anxiety and some other CNS disorders, though confirmatory trials are warranted to substantiate these effects in the clinical setting. Data regarding many aspects of this plant such as mechanisms of actions, pharmacokinetics, adverse effects of the extracts, potential interactions with standard-of-care medications and active compounds is still limited which call for additional studies particularly in humans.

Garcia-Molina, A; Ensenat, A

2017-01-16

Every day millions of professionals use a countless number of technical words to refer to the different structures inside the skull. But few of them would know how to explain their origin. In this study we take an in-depth look into the etymological origins of some of these neuroanatomical terms. The study takes an etymological tour of the central nervous system. It is in no way meant to be an exhaustive, detailed review of the terms currently in use, but instead a means to familiarise the reader with the linguistic past of words like brain, hippocampus, thalamus, claustrum, fornix, corpus callosum or limbic system. All of them come from either Greek or Latin, which were used for centuries as the lingua francas of science. The study also analyses the evolution of the word meninges, originally of Greco-Latin origin, although its current usages derive from Arabic. The neuroanatomical terms that are in use today do not come from words that associate a particular brain structure with its function, but instead from words that reflect the formal or conceptual similarity between a structure and a familiar or everyday entity (for example, an object or a part of the human body). In other cases, these words indicate the spatial location of the neuroanatomical structure with respect to a third, or they may be terms derived from characters in Greco-Latin mythology.

Currently, nutrition and health linkages focused on emerging strategy of diet based regimen to combat various physiological threats including cardiovascular disorders, oxidative stress, diabetes mellitus, etc. In this context, consumption of fruits and vegetables is gaining considerable importance as safeguard to maintain human health. Likewise, their phytochemicals and bioactive molecules are also becoming popular as promising demulcent against various ailments. The current review is an effort to sum up information regarding persimmon fruit with special reference to its phytochemistry and associated health claims. Accordingly, the role of its certain bioactive molecules like proanthocyanidin, carotenoids, tannins, flavonoids, anthocyanidin, catechin, etc. is highlighted. Owing to rich phytochemistry, persimmon and its products are considered effective in mitigating oxidative damage induced by reactive oxygen species (ROS). The antioxidant potential is too responsible for anti-malignant and anti-melanogenic perspectives of persimmon functional ingredients. Additionally, they are effectual in soothing lifestyle related disparities e.g. cardiovascular disorders and diabetes mellitus. There are proven facts that pharmacological application of persimmon or its functional ingredients like proanthocyanidin may helps against hyperlipidemia and hyperglycemia. Nevertheless, astringent taste and diospyrobezoars formation are creating lacuna to prop up its vitality. In toto, persimmon and its components hold potential as one of effective modules in diet based therapy; however, integrated research and meta-analysis are still required to enhance meticulousness.

Jatropha gossypiifolia L. (Euphorbiaceae), widely known as “bellyache bush,” is a medicinal plant largely used throughout Africa and America. Several human and veterinary uses in traditional medicine are described for different parts and preparations based on this plant. However, critical reviews discussing emphatically its medicinal value are missing. This review aims to provide an up-to-date overview of the traditional uses, as well as the phytochemistry, pharmacology, and toxicity data of J. gossypiifolia species, in view of discussing its medicinal value and potential application in complementary and alternative medicine. Pharmacological studies have demonstrated significant action of different extracts and/or isolated compounds as antimicrobial, anti-inflammatory, antidiarrheal, antihypertensive, and anticancer agents, among others, supporting some of its popular uses. No clinical trial has been detected to date. Further studies are necessary to assay important folk uses, as well as to find new bioactive molecules with pharmacological relevance based on the popular claims. Toxicological studies associated with phytochemical analysis are important to understand the eventual toxic effects that could reduce its medicinal value. The present review provides insights for future research aiming for both ethnopharmacological validation of its popular use and its exploration as a new source of herbal drugs and/or bioactive natural products.

Dietary spices and their active constituents provide various beneficial effects on the gastrointestinal system by variety of mechanisms such as influence of gastric emptying, stimulation of gastrointestinal defense and absorption, stimulation of salivary, intestinal, hepatic, and pancreatic secretions. Capsicum annuum (Solanaceae), commonly known as chilli, is a medicinal spice used in various Indian traditional systems of medicine and it has been acknowledged to treat various health ailments. Therapeutic potential of chilli and capsaicin were well documented; however, they act as double-edged sword in many physiological circumstances. In traditional medicine chilli has been used against various gastrointestinal complains such as dyspepsia, loss of appetite, gastroesophageal reflux disease, gastric ulcer, and so on. In chilli, more than 200 constituents have been identified and some of its active constituents play numerous beneficial roles in various gastrointestinal disorders such as stimulation of digestion and gastromucosal defense, reduction of gastroesophageal reflux disease (GERD) symptoms, inhibition of gastrointestinal pathogens, ulceration and cancers, regulation of gastrointestinal secretions and absorptions. However, further studies are warranted to determine the dose ceiling limit of chilli and its active constituents for their utilization as gastroprotective agents. This review summarizes the phytochemistry and various gastrointestinal benefits of chilli and its various active constituents.

Phytochemicals of medicinal plants encompass a diverse chemical space for drug discovery. India is rich with a flora of indigenous medicinal plants that have been used for centuries in traditional Indian medicine to treat human maladies. A comprehensive online database on the phytochemistry of Indian medicinal plants will enable computational approaches towards natural product based drug discovery. In this direction, we present, IMPPAT, a manually curated database of 1742 Indian Medicinal Plants, 9596 Phytochemicals, And 1124 Therapeutic uses spanning 27074 plant-phytochemical associations and 11514 plant-therapeutic associations. Notably, the curation effort led to a non-redundant in silico library of 9596 phytochemicals with standard chemical identifiers and structure information. Using cheminformatic approaches, we have computed the physicochemical, ADMET (absorption, distribution, metabolism, excretion, toxicity) and drug-likeliness properties of the IMPPAT phytochemicals. We show that the stereochemical complexity and shape complexity of IMPPAT phytochemicals differ from libraries of commercial compounds or diversity-oriented synthesis compounds while being similar to other libraries of natural products. Within IMPPAT, we have filtered a subset of 960 potential druggable phytochemicals, of which majority have no significant similarity to existing FDA approved drugs, and thus, rendering them as good candidates for prospective drugs.

Saussurea involucrata Matsum. & Koidz. is an endangered species of the Asteraceae family, growing in the high mountains of central Asia. It has been, and is, widely used in traditional Uyghur, Mongolian and Kazakhstan medicine as well as in Traditional Chinese Medicine as Tianshan Snow Lotus (Chinese: ). In traditional medical theory, S. involucrata can promote blood circulation, thereby alleviating all symptoms associated with poor circulation. It also reputedly eliminates cold and dampness from the body, diminishes inflammation, invigorates, and strengthens Yin and Yang. It has long been used to treat rheumatoid arthritis, cough with cold, stomach ache, dysmenorrhea, and altitude sickness in Uyghur and Chinese medicine. To comprehensively summarize the miscellaneous research that has been done regarding the botany, ethnopharmacology, phytochemistry, biological activity, and toxicology of S. involucrata. An extensive review of the literature was carried out. Apart from different electronic databases including SciFinder, Chinese National Knowledge Infrastructure (CNKI), ScienceDirect that were sourced for information, abstracts, full-text articles and books written in English and Chinese, including those traditional records tracing back to the Qing Dynasty. Pharmacopoeia of China and other local herbal records in Uighur, Mongolian and Kazakhstan ethnomedicines were investigated and compared for pertinent information. The phytochemistry of S. involucrata has been comprehensively investigated. More than 70 compounds have been isolated and identified; they include phenylpropanoids, flavonoids, coumarins, lignans, sesquiterpenes, steroids, ceramides, polysaccharides. Scientific studies on the biological activity of S. involucrata are equally numerous. The herb has been shown to have anti-neoplastic, anti-inflammatory, analgesic, anti-oxidative, anti-fatigue, anti-aging, anti-hypoxic, neuroprotective and immunomodulating effects. Many have shown correlations to the traditional clinical applications in Traditional Chinese Medicine and medicines. The possible mechanisms of S. involucrata in treating various cancers are revealed in the article, these include inhibition of cancer cells by affecting their growth, adhesion, migration, aggregation and invasion, inhibition of epidermal growth factor receptor signaling in cancer cells, hindrance of cancer cell proliferation, causing cytotoxicity to cancer cells and promoting expression of tumor suppressor genes. Dosage efficacy is found to be generally concentration- and time-dependent. However, studies on the correlation between particular chemical constituents and specific bioactivities are limited. In this review, we have documented the existing traditional uses of S. involucrata and summarized recent research into the phytochemistry and pharmacology of S. involucrata. Many of the traditional uses have been validated by phytochemical and modern pharmacological studies but there are still some areas where the current knowledge could be improved. Although studies have confirmed that S. involucrata has a broad range of bioactivities, further in-depth studies on the exact bioactive molecules and the mechanism of action are expected. Whether we should use this herb independently or in combination deserves to be clarified. The exact quality control as well as the toxicology studies is necessary to guarantee the stability and safety of the clinic use. The sustainable use of this endangered resource was also addressed. In conclusion, this review was anticipated to highlight the importance of S. involucrata and provides some directions for the future development of this plant. Copyright © 2015 Elsevier Ireland Ltd.

Symmetry is believed to be a hallmark of appealing faces. However, this does not imply that the most aesthetically pleasing proportions are necessary those that arise from the simple division of the face into thirds or fifths. Based on the etymology of the word symmetry, as well as on specific examples and theories of beauty, we conclude that φ-value, a ratio also known as the golden ratio or the divine proportion, can also characterize symmetrical forms. Therefore, we propose the utilization of this ratio in facial aesthetics.

Medical etymology sometimes provides unexpected information about health concepts and medical practice in different times and cultures. We conducted an etymological analysis of the terms used to indicate "liver" in Germanic and Romance languages. The Greek word "hèpar" was originally connected to the concept of "pleasure", showing that in antiquity the liver was considered to be the seat of soul and human feelings. In Romance languages, the Latin term "ficatum" was linked to the ancient practice of fattening geese with figs (ficus in Latin) to make their livers more delicious. This relationship between the liver, fat, and carbohydrates seems to indicate that ancient gourmets had clear knowledge of the nutritional mechanisms underlying "fatty liver" in animals. On the other hand, the Germanic term "lifere" was initially connected to "life", underscoring the relation of the liver to health and existence. In the Early Modern Age, the liver became a recurring image in political reflection, especially within the Elizabethan tradition of the body politic, where the king was frequently described as the "liver" of his country. Finally, the liver was used to indicate courage, or the lack of it: some modern French and English idiomatic expressions derive from the ancient belief that people who had no blood in their liver ("lily-livered") would thus be cowards or betrayers.

ElSohly, Mahmoud A; Radwan, Mohamed M; Gul, Waseem; Chandra, Suman; Galal, Ahmed

Cannabis (Cannabis sativa, or hemp) and its constituents-in particular the cannabinoids-have been the focus of extensive chemical and biological research for almost half a century since the discovery of the chemical structure of its major active constituent, Δ 9 -tetrahydrocannabinol (Δ 9 -THC). The plant's behavioral and psychotropic effects are attributed to its content of this class of compounds, the cannabinoids, primarily Δ 9 -THC, which is produced mainly in the leaves and flower buds of the plant. Besides Δ 9 -THC, there are also non-psychoactive cannabinoids with several medicinal functions, such as cannabidiol (CBD), cannabichromene (CBC), and cannabigerol (CBG), along with other non-cannabinoid constituents belonging to diverse classes of natural products. Today, more than 560 constituents have been identified in cannabis. The recent discoveries of the medicinal properties of cannabis and the cannabinoids in addition to their potential applications in the treatment of a number of serious illnesses, such as glaucoma, depression, neuralgia, multiple sclerosis, Alzheimer's, and alleviation of symptoms of HIV/AIDS and cancer, have given momentum to the quest for further understanding the chemistry, biology, and medicinal properties of this plant.This contribution presents an overview of the botany, cultivation aspects, and the phytochemistry of cannabis and its chemical constituents. Particular emphasis is placed on the newly-identified/isolated compounds. In addition, techniques for isolation of cannabis constituents and analytical methods used for qualitative and quantitative analysis of cannabis and its products are also reviewed.

Depression is a major mental disorder, and is currently recognized as the second-leading cause of disability worldwide. However, the therapeutic effect of antidepressants remains unsatisfactory. For centuries, Chinese herbal formulas (CHFs) have been widely used in the treatment of depression, achieving better therapeutic effects than placebo and having fewer side effects than conventional antidepressants. Here, we review the ethnopharmacology, phytochemistry, and pharmacology studies of nine common CHFs: “banxia houpo” decoction, “chaihu shugansan”, “ganmaidazao” decoction, “kaixinsan”, “shuganjieyu” capsules, “sinisan”, “wuling” capsules, “xiaoyaosan”, and “yueju”. Eight clinical trials and seven meta-analyses have supported the theory that CHFs are effective treatments for depression, decreasing Hamilton Depression Scale scores and showing few adverse effects. Evidence from 75 preclinical studies has also elucidated the multitarget and multipathway mechanisms underlying the antidepressant effect of the nine CHFs. Decoctions, capsules, and pills all showed antidepressant effects, ranked in descending order of efficacy. According to traditional Chinese medicine theory, these CHFs have flexible compatibility and mainly act by soothing the liver and relieving depression. This review highlights the effective treatment choices and candidate compounds for patients, practitioners, and researchers in the field of traditional Chinese medicine. In summary, the current evidence supports the efficacy of CHFs in the treatment of depression, but additional large-scale randomized controlled clinical trials and sophisticated pharmacology studies should be performed.

2013-10-01

Species of the carnivorous genus Drosera L. have long been a source of valuable natural products. The various phytochemicals characteristic of these species, particularly 1,4-naphthoquinones and flavonoids, have contributed to the diverse utilization of sundews in traditional medicine systems worldwide. A growing number of studies have sought to investigate the comparative phytochemistry of Drosera species for improved sources of pharmaceutically important compounds. The outcomes of these studies are here collated, with emergent trends discussed in detail. Important factors which affect production of secondary metabolites in plants are critically examined, such as environmental influences and in vitro culture, and recommendations subsequently presented based on this. Explicitly, the current review aims to i) present an updated, comprehensive listing of the phytochemical constituents of the genus (including quantitative data where available), ii) summarize important factors which may influence the production of phytopharmaceuticals in plants, and iii) recommend guidelines for future research based on the above, including improved standardization and quality control. We have also included a section discussing future perspectives of research on Drosera spp. based on three different research lines i) the potential to produce much needed lead compounds for treatment of tuberculosis, ii) the potential role of anthocyanins in nitrogen transport, and iii) research into 'Natural Deep Eutectic' solvents produced by Drosera spp. in the droplets or 'dew' employed to capture insect prey.

Gymnadenia conopsea (L.) R. Br. (Orchidaceae) is a perennial herbaceous orchid plant that grows widely throughout Europe and in temperate and subtropical zones of Asia. In China, its tuber has been used in traditional Chinese medicines, Tibetan medicines, Mongolian medicines and other ethnic medicines, and taken to treat numerous health conditions. The present paper provides a review of the traditional uses, phytochemistry, biological activities, and toxicology to highlight the future prospects of the plant. More than 120 chemical compounds have been isolated, and the primary components are glucosides, dihydrostilbenes, phenanthrenes, aromatic compounds, and other compounds. G. conopsea and its active constituents possess broad pharmacological properties, such as the tonifying effect, anti-oxidative activity, anti-viral activity, immunoregulatory, antianaphylaxis, antigastric ulcer, sedative, and hypnotic activities, etc. However, overexploitation combined with the habitat destruction has resulted in the rapid decrease of the resources of this plant, and the sustainable use of G. conopsea is necessary to study. Meanwhile, the toxicity of this plant had not been comprehensively studied, and the active constituents and the mechanisms of action of the tuber were still unclear. Further, studies on G. conopsea should lead to the development of scientific quality control and new drugs and therapies for various diseases; thus, its use and development require additional investigation.

The Daniel K. Inouye College of Pharmacy, during a historic event in Spring 2016, graduated the first two students in the Pacific region to earn a PhD in pharmaceutical sciences at the University of Hawai‘i at Hilo. The college offers PhD programs in these five disciplines: Cancer Biology, Medicinal Chemistry, Pharmaceutics, Pharmacognosy, and Pharmacology. One of the Pharmacognosy dissertations focused on plant-derived natural products with potential anti-inflammatory and cancer chemopreventive activities. Physalis peruviana (Pp) L. originated in tropical South America. It has become naturalized and is found readily on the Island of Hawai‘i. The edible fruits are commonly known as cape gooseberry or poha in Hawai‘i. In part of our study, three new withanolides, physaperuvin G (1), physaperuvins I–J (2–3), along with four known withanolides, namely, 4β-hydroxywithanolide E (4), withaperuvin C (5), and physalactone (6), coagulin (7) were isolated from the aerial parts of P. peruviana. In addition, two known compounds, phyperunolide F (8), and withanolide S (9), were isolated and identified from the poha berry fruits. The structures and absolute stereochemistry of new compounds from poha were elucidated by several spectroscopy methods: Nuclear Magnetic Resonance (NMR) spectroscopy, X-ray diffraction, and mass spectrometry analyses. All isolated poha compounds (aerial parts and fruits) were evaluated for their anti-inflammatory activity with lipopolysaccharide (LPS)-activated murine macrophage RAW 264.7 cells, and tumor necrosis factor alpha (TNF-α)-activated nuclear factor-kappa B (NF-κB) with transfected human embryonic kidney cells 293. Most of the isolated natural compounds showed activity with these assays. Additional studies were performed with models of colon cancer. Specifically, 4β-hydroxywithanolide E (4HWE) inhibited the growth of colon cancer monolayer and spheroid cultures. The compound induced cell cycle arrest at low concentrations and apoptosis at higher concentrations. These data suggest the ingestion of poha berries may have some effect on the prevalence of colon cancer. Additionally, poha isolates compounds were evaluated for their growth inhibitory effects with U251MG glioblastoma and MDA-MB-231 breast cancer cells that harbor aberrantly-active signal transducer and activation of transcription 3 (STAT3), compared to normal NIH-3T3 mouse fibroblasts. This work has led to the filing of three provisional patents with the University of Hawai‘i Office of Technology Transfer and Economic Development. PMID:27920947

The historical Latin and etymology of selected anatomical terms of the larynx.

PubMed

Lydiatt, Daniel D; Bucher, Gregory S

2010-03-01

The etymological evolution of the anatomical terms larynx, cricoid, glottis, epiglottis, and thyroid (cartilage) dates to antiquity. Human dissection replaced animal in the 16th and 17th centuries and terms evolved. This evolution was recorded in the literature largely in Latin. We translated key studies of laryngeal anatomy from the 16th century to better understand this evolution. We present the Latin with our translations, and historical commentary as essential to this understanding. Vesalius favored the Latin scutiform (shield) for the thyroid cartilage, but recognized peltalis (shield). The Basle Nomina Anatomica (BNA) chose the Greek thyroid (theta upsilon rho epsilon omicron epsilon iota delta eta) for modern convention. Vesalius used the name "innominate" for the cricoid cartilage, but described its resemblance to a ring, drawn in the margin of the Fabrica. Krikoid, the Greek for ring shaped, was adopted by the BNA. Although the term arytenoid was used for centuries, Vesalius argued the Greek name referred to the spout of a cup or ladle. He recognized the human arytenoids as two separate cartilages as opposed to single in certain animals. The glottis was defined by Vesalius as the vocal fold or rima glottidis of today, and he advanced its function by understanding the paired, mobile arytenoid cartilages. He defined the function of the epiglottis and first described the pre-epiglottic space. Vesalius' student at Padua, Italy, Columbo contributed to anatomical knowledge, but animosity between them clouded the record. Harvey, working 75 years later in England, offers an evolutionary window from Vesalius. Harvey's laryngeal studies preceded by a decade his groundbreaking studies on the circulation of blood.

Y-chromosome diversity in Catalan surname samples: insights into surname origin and frequency

PubMed Central

Solé-Morata, Neus; Bertranpetit, Jaume; Comas, David; Calafell, Francesc

2015-01-01

The biological behavior of the Y chromosome, which is paternally inherited, implies that males sharing the same surname may also share a similar Y chromosome. However, socio-cultural factors, such as polyphyletism, non-paternity, adoption, or matrilineal surname transmission, may prevent the joint transmission of the surname and the Y chromosome. By genotyping 17 Y-STRs and 68 SNPs in ~2500 male samples that each carried one of the 50 selected Catalan surnames, we could determine sets of descendants of a common ancestor, the population of origin of the common ancestor, and the date when such a common ancestor lived. Haplotype diversity was positively correlated with surname frequency, that is, rarer surnames showed the strongest signals of coancestry. Introgression rates of Y chromosomes into a surname by non-paternity, adoption, and transmission of the maternal surname were estimated at 1.5−2.6% per generation, with some local variation. Average ages for the founders of the surnames were estimated at ~500 years, suggesting a delay between the origin of surnames (twelfth and thirteenth centuries) and the systematization of their paternal transmission. We have found that, in general, a foreign etymology for a surname does not often result in a non-indigenous origin of surname founders; however, bearers of some surnames with an Arabic etymology show an excess of North African haplotypes. Finally, we estimate that surname prediction from a Y-chromosome haplotype, which may have interesting forensic applications, has a ~60% sensitivity but a 17% false discovery rate. PMID:25689924

Origanum onites L., known as Turkish oregano, has great traditional, medicinal, preservative, and commercial importance. It is used for the treatment of several kinds of ailments, such as gastrointestinal disorders, diabetes, high cholesterol, leukemia, bronchitis, etc. In this review, traditional use, phytochemistry, and pharmacology of O. onites reported between 1988 and 2014 were discussed. This review was prepared based on literature survey on scientific journals and books from libraries and electronic sources, such as Web of Science, PubMed, Scopus, Google Scholar, etc. All databases were searched up to June 2014. Several different classes of terpenoids, triterpene acids, phenolic acids, hydroquinones, flavonoids, hydrocarbons, sterols, pigments, fatty acids, tocopherols, and inorganic compounds were detected mainly in the aerial parts of this plant. Pharmacological studies revealed that extracts obtained from several solvents and individual compounds exhibited antimicrobial, antiviral, antioxidant, insecticidal, anticancer, hepatoprotective, genotoxic, antidiabetic, cholinesterase inhibitory, anti-inflammatory, analgesic activities, etc. O. onites, in general, exhibited remarkable activity potential in almost all test systems. The results of toxicity studies indicated that O. onites did not show any significant toxicity and mutagenicity on Drosophila and Salmonella. Toxicity of the extracts/essential oils and also individual compounds should be evaluated on mammalian cells to ensure their safety. The bioactivity of individual compounds aside from terpenoids should also be assessed in detail. Additionally, mode of action for the bioactive compounds should be evaluated to understand the complex pharmacological effects of these phytochemicals. © 2016 Verlag Helvetica Chimica Acta AG, Zürich.

Zingiber zerumbet (L.) Roscoe ex Sm. (family, Zingiberaceae) is a potent medicinal herb widely known as shampoo ginger and its rhizome is used in numerous ethnomedicinal applications including antipyretic, anti-inflammatory, antibacterial, anti-diarrheal, antidiabetics, carminative, and diuretic. The aim of this review was to bring together all the scientific updates on the phytochemistry and pharmacological activities of this herb, including their toxicological studies, and critically analyzed the outcomes to provide directions for future research on the herb as potential source of bioactive metabolites for pharmaceutical and nutraceutical applications. A structured electronic search on worldwide accepted scientific databases (Web of Science, PubMed, Google Scholar, Science Direct, SciFinder, Wiley Online Library) was carried out to compile the relevant information. Some information was obtained from books and database on medicinal plants used in various countries. About 60 metabolites, mainly polyphenols, and terpenoids have been isolated and identified. However, most of the reported pharmacological studies were based on crude extracts, and only a few of those isolated metabolites, particularly zerumbone have been investigated for biological and pharmacological activities. Many of the mechanistic studies to understand the pharmacological effects of the plant are limited by many considerations with regard to design, experimentation and interpretation. The bioactive metabolites should be further investigated on their safety and more elaborate preclinical studies before clinical trials can be undertaken.

For compliance with US Current Good Manufacturing Practice regulations for dietary supplements, manufacturers must provide identity of source plant material. Despite the popularity of hawthorn as a dietary supplement, relatively little is known about the comparative phytochemistry of different hawthorn species, and in particular North American hawthorns. The combination of NMR spectrometry with chemometric analyses offers an innovative approach to differentiating hawthorn species and exploring the phytochemistry. Two European and two North American species, harvested from a farm trial in late summer 2008, were analyzed by standard 1D 1 H and J-resolved (JRES) experiments. The data were preprocessed and modelled by principal component analysis (PCA). A supervised model was then generated by partial least squares-discriminant analysis (PLS-DA) for classification and evaluated by cross validation. Supervised random forests models were constructed from the dataset to explore the potential of machine learning for identification of unique patterns across species. 1D 1 H NMR data yielded increased differentiation over the JRES data. The random forests results correlated with PLS-DA results and outperformed PLS-DA in classification accuracy. In all of these analyses differentiation of the Crataegus spp. was best achieved by focusing on the NMR spectral region that contains signals unique to plant phenolic compounds. Identification of potentially significant metabolites for differentiation between species was approached using univariate techniques including significance analysis of microarrays and Kruskall-Wallis tests.

Petiveria alliacea L. commonly grows in the tropical regions of the Americas such as the Amazon forest, Central America, Caribbean islands and Mexico, as well as specific regions of Africa. Popularly known by several different names including 'mucuracaá', 'guiné' and 'pipi', P. alliacea has been used in traditional medicine for the treatment of various central nervous system (CNS) disorders, such as anxiety, pain, memory deficits and seizures, as well as for its anaesthetic and sedative properties. Furthermore, the use of this species for religious ceremonies has been reported since the era of slavery in the Americas. Therefore, the present review aims to provide a critical and comprehensive overview of the ethnobotany, phytochemistry and pharmacological properties of P. alliacea, focusing on CNS pharmacological effects, in order to identify scientific lacunae and to open new perspectives for future research. A literature search was performed on P. alliacea using ethnobotanical textbooks, published articles in peer-reviewed journals, unpublished materials, government survey reports and scientific databases such as PubMed, Scopus, Web of Science, Science Direct and Google Scholar. The Plant List, International Plant Name Index and Kew Botanical Garden Plant name databases were used to validate the scientific names. Crude extracts, fractions and phytochemical constituents isolated from various parts of P. alliacea show a wide spectrum of neuropharmacological activities including anxiolytic, antidepressant, antinociceptive and anti-seizure, and as cognitive enhancers. Phytochemistry studies of P. alliacea indicate that this plant contains a diversity of biologically active compounds, with qualitative and quantitative variations of the major compounds depending on the region of collection and the harvest season, such as essential oil (Petiverina), saponinic glycosides, isoarborinol-triterpene, isoarborinol-acetate, isoarborinol-cinnamate, steroids, alkaloids, flavonoids and tannins. Root chemical analyses have revealed coumarins, benzyl-hydroxy-ethyl-trisulphide, benzaldehyde, benzoic acid, dibenzyl trisulphide, potassium nitrate, b-sitosterol, isoarborinol, isoarborinol-acetate, isoarborinol-cinnamate, polyphenols, trithiolaniacine, glucose and glycine. Many traditional uses of P. alliacea have now been validated by modern pharmacology research. The available data reviewed here support the emergence of P. alliacea as a potential source for the treatment of different CNS disorders including anxiety, depression, pain, epilepsy and memory impairments. However, further studies are certainly required to improve the knowledge about the mechanisms of action, toxicity and efficacy of the plant as well as about its bioactive compounds before it can be approved in terms of its safety for therapeutic applications.

Himalayan paeony (Paeonia emodi Royle.) is an important species used to treat various diseases. This study aimed to compile the detailed traditional medicinal uses, phytochemistry, pharmacology and toxicological investigations on P. emodi. This study also highlights taxonomic validity, quality of experimental designs and shortcomings in previously reported information on Himalayan paeony. The data was extracted from unpublished theses (Pakistan, China, India and Nepal), and different published research articles confined to pharmacology, phytochemistry and antimicrobial activities using different databases through specific keywords. The relevant information regarding medicinal uses, taxonomic/common names, part used, collection and identification source, authentication, voucher specimen number, plant extracts and their characterization, isolation and identification of phytochemicals, methods of study in silico, in vivo or in vitro, model organism used, dose and duration, minimal active concentration, zone of inhibition (antimicrobial study), bioactive compound(s), mechanism of action on single or multiple targets, and toxicological information. P. emodi is reported for diverse medicinal uses with pharmacological properties like antioxidant, nephroprotective, lipoxygenase inhibitory, cognition and oxidative stress release, cytotoxic, anti-inflammatory, antiepileptic, anticonvulsant, haemaglutination, alpha-chymotrypsin inhibitory, hepatoprotective, hepatic chromes and pharmacokinetics of carbamazepine expression, β-glucuronidase inhibitory, spasmolytic and spasmogenic, and airway relaxant. Data confined to its taxonomic validity, shows 10% studies with correct taxonomic name while 90% studies with incorrect taxonomic, pharmacopeial and common names. The literature reviewed, shows lack of collection source (11 reports), without proper source of identification (15 reports), 33 studies without voucher specimen number, 26 reports lack information on authentic herbarium submission and most of the studies (90%) without validation of taxonomic names using recognized databases. In reported methods, 67% studies without characterization of extracts, 25% lack proper dose, 40% without duration and 31% reports lack information on proper controls. Similarly, only 18% studies reports active compound(s) responsible for pharmacological activities, 14% studies show minimal active concentration, only 2.5% studies report mechanism of action on target while none of the reports mentioned in silico approach. P. emodi is endemic to Himalayan region (Pakistan, China, India and Nepal) with diverse traditional therapeutic uses. Majority of reviewed studies showed confusion in its taxonomic validity, incomplete methodologies and ambiguous findings. Keeping in view the immense uses of P. emodi in various traditional medicinal systems, holistic pharmacological approaches in combination with reverse pharmacology, system biology, and "omics" technologies are recommended to improve the quality of research which leads to natural drug discovery development at global perspectives.

Euler, Karl-Jaochim

1982-10-01

Manganese dioxide was known two thousand years ago. It was described by Plinius. Later, Basilius Valentinus named it "Braunstein", the brownstone. Its chemical nature was recognized by Scheele and his student Gahn. Its first application in the field of batteries seems to have been by Ritter. Following Leclanchéś invention it has been used on a large scale in dry batteries. In 1977 about 300 000 metric tons of battery grade manganese dioxide were consumed. More than 50% of the oxide is derived from natural ores, and about one third is obtained as electrochemically deposited dioxide.

A variety of ion sources, including the EBIS and ECRIS, are distinguished by their ability to produce low-energy ions of very high charge state. It would be useful to have some figure of merit that is particularly sensitive to this performance. I propose here such a quantity, called Quightness,'' which is related to brightness but which enhances the contrast between sources supplying multicharged ions of low energy. The rationale for introducing this quantity, its etymology and relationship to other figures of merit, and some representative values are presented.

2015-09-01

The "Colóquios dos simples e drogas he cousas medicinais de Índia" (Conversations on the simples, drugs and medicinal substances of India) (1563) of Garcia da Orta is a botanical and pharmacognosy book. The author is a Portuguese physician who studied in the Spanish universities and practiced medicine mainly in India. He studies in short chapters presented in the form of dialogues about sixty simples. Sources to which he refers are indicative of a "classical" training, but also the mark of a curious and open mind to different cultures. The Arabic sources are numerous and mainly concern the identification of substances by abundant synonyms of their names in foreign languages and different medicinal uses that may have been done by the ancient physicians. However, Da Orta is critical with respect to these sources, seeking contradictions and differences of opinion among authors. He confronts them with the oral information collected thanks to a wide network of contacts.

Pharmacy education programs in Vietnam are complex and offer various career pathways. All include theory and laboratory modules in general, foundation, and pharmaceutical knowledge; placements in health facilities; and a final examination. The various pharmacy degree programs allow specialization in 1 or more of 5 main fields: (1) drug management and supply, (2) drug development and production, (3) pharmacology and clinical pharmacy, (4) traditional medicine and pharmacognosy, and (5) drug quality control, which are offered as main specialization options during the reformed undergraduate and postgraduate programs. However, pharmacy education in Vietnam in general remains product oriented and clinical pharmacy training has not received adequate attention. Only students who have obtained the bachelor of pharmacy degree, which requires a minimum of 5 years of study, are considered as fully qualified pharmacists. In contrast, an elementary diploma in pharmacy awarded after 1 year of pharmacy study permits entry into more junior pharmacy positions. Since the 2000s, there has been a surge in the number and types of schools offering pharmacy qualifications at various levels. PMID:23966717

Tracking targets of natural products is one of the most challenging issues in fields ranging from pharmacognosy to biomedicine. It is widely recognized that the biocompatible nanoparticle (NP) could function as a "key" that opens the target "lock". We report a functionalized poly-lysine NP technique that can monitor the target protein of arctigenin (ATG) in vivo non-invasively. The NPs were synthesized, and their morphologies and surface chemical properties were characterized by transmission electron microscopy (TEM), laser particle size analysis and atomic force microscopy (AFM). In addition, we studied the localization of ATG at the level of the cell and the whole animal (zebrafish and mice). We demonstrated that fluorescent NPs could be ideal carriers in the development of a feasible method for target identification. The distributions of the target proteins were found to be consistent with the pharmacological action of ATG at the cellular and whole-organism levels. The results indicated that functionalized poly-lysine NPs could be valuable in the multimodal imaging of arctigenin.

2016-10-15

Geriatrics are a group of patients over 65 years and with multiple comorbidities and different functional impairments. Apart from decline in body mass, presence of exhaustion and general fatigue, an aged person may also suffer from various disorders. Approximately, around 30% of geriatric subjects have significant cardiovascular ailments. Apart from the intensive management of cardiovascular aspects in elderly, monitoring of the complementary cardiac medicine in those people should be received more attention. There are many management lines for a cardio-geriatric condition in Traditional Persian Medicine (TPM). Accordingly, this paper aimed to deal with those medicaments as well as evidence-based clinical aspects and phytochemistry. By searching through main pharmaceutical manuscripts of Persian medicine during 10th-18th centuries (A.D.), concurrently, natural medicines for geriatrics and remedies for cardiovascular ailments were derived. On the other side, related phytochemical and pharmacological aspects of those remedies were highlighted. In all, 38 cardiovascular and 34 geriatric medicaments were found in those manuscripts. Antihyperlipidemic and cholesterol lowering activities of those medicines were the most reported activities in current medicine. However, other pharmacological reports were related to hypotensive, coagulant, cardio-protective and cardiotonic activities. In regard of the chemical composition, medicaments were mainly of polyphenols and flavonoids and also most of the employed extracts and fractions were yielded from polar or semi-polar solvents. With reference to these findings, flavonoid-rich medicaments from Persian medicine may be selected as considerable herbs for geriatrics with cardiovascular ailments. Copyright © 2016 Elsevier GmbH.

2015-01-01

Bixa orellana commonly known as annatto is one of the oldest known natural dye yielding plants native to Central and South America. Various parts of annatto have been widely used in the traditional medical system for prevention and treatment of a wide number of health disorders. The plethora of traditional uses has encouraged researchers to identify and isolate phytochemicals from all parts of this plant. Carotenoids, apocarotenoids, terpenes, terpenoids, sterols, and aliphatic compounds are main compounds found in all parts of this plant and are reported to exhibit a wide range of pharmacological activities. In recent years annatto has received tremendous scientific interest mainly due to the isolation of yellow–orange natural dye from its seeds which exhibits high biodegradability, low toxicity, and compatibility with the environment. Considerable research work has already been done and is currently underway for its applications in food, textile, leather, cosmetic, solar cells, and other industries. The present review provides up-to-date systematic and organized information on the traditional usage, phytochemistry and pharmacology of annatto. It also highlights its non-food industrial applications in order to bring more interest on this dye plant, identifies the existing gaps and provides potential for future studies. Studies reported in this review have demonstrated that annatto holds a great potential for being exploited as source of drugs and a potential natural dye. However, further efforts are required to identify extract biomolecules and their action mechanisms in exhibiting certain biological activities in order to understand the full phytochemical profile and the complex pharmacological effects of this plant.

2001-01-01

Etymologically, the word 'Caesar' originates from the Latin word 'Caedaere' meaning - 'to cut'. So cutting remains the core point, but little is known about the real origin of the history of Caesarean Section. There is evidence that, the ancient Hindus excelled in surgery and many operations were performed, including caesarean section. This operation was mentioned several times in the Mishnah of Rabbi Judah, the first large commentary on the Hebrew Bible. There are also several mythological anecdotes in Hindu, Buddhist and Greek mythologies. The myth of caesarean section did not even escape the keen eyes of William Skakespeare. The landmarks, treatises and the advancement in this operative procedure are presented in this article.

War, suffering and modern German history.

This introduction proceeds in five steps. First, it briefly considers the etymology of the term "suffering," as well as the way in which scholars from different disciplines have approached it conceptually and empirically. Second, drawing on the contributions to this issue, it raises general themes emerging from the study of the Thirty Years, Franco-Prussian and First World Wars, with particular attention to gender, the disabled, and Jewish-German veterans. Finally, it considers the most politically contested field of German suffering - the Second World War - and reflects on how that suffering can be narrated and understood without running into the intellectual dead ends of either self-pity or collective guilt.

The Daniel K. Inouye College of Pharmacy, during a historic event in Spring 2016, graduated the first two students in the Pacific region to earn a PhD in pharmaceutical sciences at the University of Hawai'i at Hilo. The college offers PhD programs in these five disciplines: Cancer Biology, Medicinal Chemistry, Pharmaceutics, Pharmacognosy, and Pharmacology. One of the Pharmacognosy dissertations focused on plant-derived natural products with potential anti-inflammatory and cancer chemopreventive activities. Physalis peruviana (Pp) L. originated in tropical South America. It has become naturalized and is found readily on the Island of Hawai'i. The edible fruits are commonly known as cape gooseberry or poha in Hawai'i. In part of our study, three new withanolides, physaperuvin G ( 1 ), physaperuvins I-J ( 2 - 3 ), along with four known withanolides, namely, 4β-hydroxywithanolide E ( 4 ), withaperuvin C ( 5 ), and physalactone ( 6 ), coagulin ( 7 ) were isolated from the aerial parts of P. peruviana . In addition, two known compounds, phyperunolide F ( 8 ), and withanolide S ( 9 ), were isolated and identified from the poha berry fruits. The structures and absolute stereochemistry of new compounds from poha were elucidated by several spectroscopy methods: Nuclear Magnetic Resonance (NMR) spectroscopy, X-ray diffraction, and mass spectrometry analyses. All isolated poha compounds (aerial parts and fruits) were evaluated for their anti-inflammatory activity with lipopolysaccharide (LPS)-activated murine macrophage RAW 264.7 cells, and tumor necrosis factor alpha (TNF-α)-activated nuclear factor-kappa B (NF-κB) with transfected human embryonic kidney cells 293. Most of the isolated natural compounds showed activity with these assays. Additional studies were performed with models of colon cancer. Specifically, 4β-hydroxywithanolide E (4HWE) inhibited the growth of colon cancer monolayer and spheroid cultures. The compound induced cell cycle arrest at low concentrations and apoptosis at higher concentrations. These data suggest the ingestion of poha berries may have some effect on the prevalence of colon cancer. Additionally, poha isolates compounds were evaluated for their growth inhibitory effects with U251MG glioblastoma and MDA-MB-231 breast cancer cells that harbor aberrantly-active signal transducer and activation of transcription 3 (STAT3), compared to normal NIH-3T3 mouse fibroblasts. This work has led to the filing of three provisional patents with the University of Hawai'i Office of Technology Transfer and Economic Development.

Elevations of carbon dioxide, temperature and ultraviolet-B (UBV) radiation in the growth environment may have a high impact on the accumulation of carbon in plants, and the different factors may work in opposite directions or induce additive effects. To detect the changes in the growth and phytochemistry of silver birch (Betula pendula) seedlings, six genotypes were exposed to combinations of ambient or elevated levels of CO2 , temperature and UVB radiation in top-closed chambers for 7 weeks. The genotypes were relatively similar in their responses, and no significant interactive effects of three-level climate factors on the measured parameters were observed. Elevated UVB had no effect on growth, nor did it alter plant responses to CO2 and/or temperature in combined treatments. Growth in all plant parts increased under elevated CO2 , and height and stem biomass increased under elevated temperature. Increased carbon distribution to biomass did not reduce its allocation to phytochemicals: condensed tannins, most flavonols and phenolic acids accumulated under elevated CO2 and elevated UVB, but this effect disappeared under elevated temperature. Leaf nitrogen content decreased under elevated CO2 . We conclude that, as a result of high genetic variability in phytochemicals, B. pendula seedlings have potential to adapt to the tested environmental changes. The induction in protective flavonoids under UVB radiation together with the positive impact of elevated CO2 and temperature mitigates possible UVB stress effects, and thus atmospheric CO2 concentration and temperature are the climate change factors that will dictate the establishment and success of birch at higher altitudes in the future. © 2013 Scandinavian Plant Physiology Society.

Pongamia pinnata (L.) Pierre is one of the many plants with diverse medicinal properties where all its parts have been used as traditional medicine in the treatment and prevention of several kinds of ailments in many countries such as for treatment of piles, skin diseases, and wounds. This review discusses the current knowledge of traditional uses, phytochemistry, biological activities, and toxicity of this species in order to reveal its therapeutic and gaps requiring future research opportunities. This review is based on literature study on scientific journals and books from library and electronic sources such as ScienceDirect, PubMed, ACS, etc. Several different classes of flavonoid derivatives, such as flavones, flavans, and chalcones, and several types of compounds including terpenes, steroid, and fatty acids have been isolated from all parts of this plant. The pharmacological studies revealed that various types of preparations, extracts, and single compounds of this species exhibited a broad spectrum of biological activities such as antioxidant, antimicrobial, anti-inflammatory, and anti-diabetic activities. The results of several toxicity studies indicated that extracts and single compounds isolated from this species did not show any significant toxicity and did not cause abnormality on some rats' organs. Thus, this plant has a potential to be used as an effective therapeutic remedy due to its low toxicity towards mammalian cells. However, further study on chemical constituents and their mechanisms in exhibiting certain biological activities are needed to understand the full phytochemical profile and the complex pharmacological effects of this plant. In addition, further study on the toxicity of the other compounds isolated from this plant required to be assessed to ensure their eligibility to be used as sources of drugs. © 2013 Elsevier Ireland Ltd.

A number of species belonging to herbal genus Aconitum are well-known and popular for their medicinal benefits in Indian, Vietnamese, Korean, Japanese, Tibetan and Chinese systems of medicine. It is a valuable drug as well as an unpredictable toxic material. It is therefore imperative to understand and control the toxic potential of herbs from this genus. In this review, the ethnomedicinal, phytochemistry, pharmacology, structure activity relationship and toxicology studies of Aconitum were presented to add to knowledge for their safe application. A total of about 76 of all aconite species growing in China and surrounding far-east and Asian countries are used for various medical purposes. The main ingredients of aconite species are alkaloids, flavonoids, free fatty acids and polysaccharides. The tuberous roots of genus Aconitum are commonly applied for various diseases such as rheumatic fever, painful joints and some endocrinal disorders. It stimulates the tip of sensory nerve fibres. These tubers of Aconitum are used in the herbal medicines only after processing. There remain high toxicological risks of the improper medicinal applications of Aconitum. The cardio and neurotoxicities of this herb are potentially lethal. Many analytical methods have been reported for quantitatively and qualitatively characterization of Aconitum. Aconitum is a plant of great importance both in traditional medicine in general and in TCM in particular. Much attention should be put on Aconitum because of its narrow therapeutic range. However, Aconitum's toxicity can be reduced using different techniques and then benefit from its pharmacological activities. New methods, approaches and techniques should be developed for chemical and toxicological analysis to improve its quality and safety. © 2014 Royal Pharmaceutical Society.

Despite the widespread use of Vernonia anthelmintica seeds in traditional medicine, the need to establish the safety of the Vernonia anthelmintica is required to ascertain the safe use of this herbal medicine. The aim of the present study is to establish the acute toxicity profile of different extracts of Vernonia anthelmintica. Hexane and ethanol extract of Vernonia Anthelmintica has been studied for its brine shrimp lethality potential. Water decoction (WDVA), Hexane (HEVA) and Ethanol (EEVA) extracts of Vernonia anthelmintica has also been evaluated for their in-vivo acute oral toxicity in mice by Lorke's method. Phytochemistry of all three extracts was also evaluated for the presence of their secondary metabolites. All three extracts showed the presence of flavonoids and terpenoids, while alkaloids, tannins and fixed oils were present in HEVA and EEVA. Furthermore EEVA also showed presence of carbohydrates and HEVA also showed the presence of cardiac glycosides. Ethanol and hexane extracts of Vernonia anthelmintica showed a positive cytotoxicity in brine shrimp lethality test at 24 hours with LC50 104.16 (224.0-48.05)μg/ml and 216.11μg/ml (378.2-128.7) respectively as compared to standard drug etoposide LC50 7.46μg/ml. The oral LD50 for EEVA, HEVA and WDVA in mice by Lorke's method was greater than 5000mg/kg. The result of brine shrimp lethality test clearly exhibited the presence of bioactive compounds with cytotoxic potential; however seems to be safe for oral use since LD50 was higher than 5000mg/kg and thus safety of acute dosing in vivo practices is justified.

The definition of ileus has undergone deep changes over the last three millennia. The term ileus was originally used in Classic Greece to describe a common cause of intestinal obstruction, and subsequently the Romans would often translate it into the Latin word volvulus. During the Renaissance, ileus, volvulus and intussusception became synonymous with a vulgar term--Miserere Mei or Miserere colic--whose origin and evolution are still much of a mystery. This paper provides some historical investigation on the Miserere Mei or Miserere colic, with the aim of discussing its evolution within medical literature during the 17th and 18th centuries.

Barron, R L; Vanscoy, G J

1993-05-01

To contrast scientific facts with suggested manufacturers' claims regarding food supplements (natural products) marketed for enhanced athletic prowess. A MEDLINE search was performed to obtain documentation supporting the claims of natural-product manufacturers. In addition, several references pertaining to pharmacognosy, natural products, herbs, pharmacy practice, and sports medicine were reviewed. Claims were obtained from promotional advertisements in bodybuilding magazines, product labels, and fact sheets for sales representatives in nutrition and health-food stores. We reviewed all of the clinical trials, published between 1966 and 1992, relative to the manufacturers' claims regarding these products. Pertinent human and/or animal studies supporting each natural product were compared with the manufacturers' claims. We found that there was no published scientific evidence to support the promotional claims for a large proportion of the products (8/19, 42 percent). Only 4 of 19 products (21 percent) were associated with any documented human clinical trials supporting their promotional claims. Six of 19 agents (32 percent) had some scientific documentation to support their promotional claims; however, these products were judged to be marketed in a misleading manner.

Sophora japonica (Fabaceae), also known as Huai (Chinese: ), is a medium-sized deciduous tree commonly found in China, Japan, Korea, Vietnam, and other countries. The use of this plant has been recorded in classical medicinal treatises of ancient China, and it is currently recorded in both the Chinese Pharmacopoeia and European Pharmacopoeia. The flower buds and fruits of S. japonica, also known as Flos Sophorae Immaturus and Fructus Sophorae in China, are most commonly used in Asia (especially in China) to treat hemorrhoids, hematochezia, hematuria, hematemesis, hemorrhinia, uterine or intestinal hemorrhage, arteriosclerosis, headache, hypertension, dysentery, dizziness, and pyoderma. To discuss feasible trends for further research on S. japonica, this review highlights the botany, ethnopharmacology, phytochemistry, biological activities, and toxicology of S. japonica based on studies published in the last six decades. Information on the S. japonica was collected from major scientific databases (SciFinder, PubMed, Elsevier, SpringerLink, Web of Science, Google Scholar, Medline Plus, China Knowledge Resource Integrated (CNKI), and "Da Yi Yi Xue Sou Suo (http://www.dayi100.com/login.jsp)" for publications between 1957 and 2015 on S. japonica. Information was also obtained from local classic herbal literature, government reports, conference papers, as well as PhD and MSc dissertations. Approximately 153 chemical compounds, including flavonoids, isoflavonoids, triterpenes, alkaloids, polysaccharides, amino acids, and other compounds, have been isolated from the leaves, branches, flowers, buds, pericarps, and/or fruits of S. japonica. Among these compounds, several flavonoids and isoflavonoids comprise the active constituents of S. japonica, which exhibit a wide range of biological activities in vitro and in vivo such as anti-inflammatory, antibacterial, antiviral, anti-osteoporotic, antioxidant, radical scavenging, antihyperglycemic, antiobesity, antitumor, and hemostatic effects. Furthermore, flavonoids and isoflavonoids can be used as quality control markers for quality identification and evaluation of medicinal materials and their preparations. Information on evaluating the safety of S. japonica is very limited, so further study is required. To enable safer, more effective, and controllable therapeutic preparations, more in-depth information is urgently needed on the quality control, toxicology data, and clinical value of crude extract and active compounds of S. japonica. S. japonica has long been used in traditional Chinese medicine (TCM) due to its wide range of biological activities, and is administered orally. Phytochemical and pharmacological studies of S. japonica have increased in the past few years, and the extract and active components of this plant can be used to develop new drugs based on their traditional application as well as their biological activities. Therefore, this review on the ethnopharmacology, phytochemistry, biological activities, and toxicity of S. japonica offers promising data for further studies as well as the commercial exploitation of this traditional medicine.

Nsuala, Baudry N; Enslin, Gill; Viljoen, Alvaro

2015-11-04

Leonotis leonurus, locally commonly known as "wilde dagga" (=wild cannabis), is traditionally used as a decoction, both topically and orally, in the treatment of a wide variety of conditions such as haemorrhoids, eczema, skin rashes, boils, itching, muscular cramps, headache, epilepsy, chest infections, constipation, spider and snake bites. The dried leaves and flowers are also smoked to relieve epilepsy. The leaves and flowers are reported to produce a mild euphoric effect when smoked and have been said to have a similar, although less potent, psychoactive effect to cannabis. To amalgamate the botanical aspects, ethnopharmacology, phytochemistry, biological activity, toxicity and commercial aspects of the scientific literature available on L. leonurus. An extensive review of the literature from 1900 to 2015 was carried out. Electronic databases including Scopus, SciFinder, Pubmed, Google Scholar and Google were used as data sources. All abstracts, full-text articles and books written in English were considered. The phytochemistry of particularly the non-volatile constituents of L. leonurus has been comprehensively investigated due to interest generated as a result of the wide variety of biological effects reported for this plant. More than 50 compounds have been isolated and characterised. L. leonurus contains mainly terpenoids, particularly labdane diterpenes, the major diterpene reported is marrubiin. Various other compounds have been reported by some authors to have been isolated from the plant, including, in the popular literature only, the mildly psychoactive alkaloid, leonurine. Leonurine has however, never been reported by any scientific analysis of the extracts of L. leonurus. Despite the publication of various papers on L. leonurus, there is still, however, the need for definitive research and clarification of other compounds, including alkaloids and essential oils from L. leonurus, as well as from other plant parts, such as the roots which are extensively used in traditional medicine. The traditional use by smoking also requires further investigation as to how the chemistry and activity are affected by this form of administration. Research has proven the psychoactive effects of the crude extract of L. leonurus, but confirmation of the presence of psychoactive compounds, as well as isolation and characterization, is still required. Deliberate adulteration of L. leonurus with synthetic cannabinoids has been reported recently, in an attempt to facilitate the marketing of these illegal substances, highlighting the necessity for refinement of appropriate quality control processes to ensure safety and quality. Much work is therefore still required on the aspect of quality control to ensure safety, quality and efficacy of the product supplied to patients, as this plant is widely used in South Africa as a traditional medicine. Commercially available plant sources provide a viable option for phytochemical research, particularly with regard to the appropriate validation of the plant material (taxonomy) in order to identify and delimit closely related species such as L. leonurus and L. nepetifolia which are very similar in habit.

Hartman (1965) described a nereidid species, Namalycastis profundus[sic], based on a deep-sea specimen collected from off Bermuda (1000 m deep) in the NW Atlantic. Although Hartman (1965) did not mention its etymology, the specific name is believed to be derived from the Latin adjective "profund-" meaning "deep." Because Namalycastis is feminine in gender (Glasby et al. 2016), the original specific name as masculine was incorrect and must be corrected to N. profunda for mandatory gender agreement under Articles 31.2 and 34.2 of the International Code of Zoological Nomenclature (hereafter, "the Code") (International Commission of Zoological Nomenclature 1999).

Cancer has been increasingly recognized as a global issue. This is especially true in countries like China, where cancer incidence has increased likely because of changes in environment and lifestyle. However, cancer is not a modern disease; early cases have been recorded in ancient medical books in the West and in China. Here, we provide a brief history of cancer, focusing on cancer of the breast, and review the etymology of ai, the Chinese character for cancer. Notable findings from both Western and Chinese traditional medicine are presented to give an overview of the most important, early contributors to our evolving understanding of human breast cancer. We also discuss the earliest historical documents to record patients with breast cancer.

The plants of the genus Peganum have a long history as a Chinese traditional medicine for the treatment of cough, hypertension, diabetes, asthma, jaundice, colic, lumbago, and many other human ailments. Additionally, the plants can be used as an amulet against evil-eye, dye and so on, which have become increasingly popular in Asia, Iran, Northwest India, and North Africa. The present paper reviewed the ethnopharmacology, phytochemistry, analytical methods, biological activities, metabolism, pharmacokinetics, toxicology, and drug interaction of the genus Peganum in order to assess the ethnopharmacological use and to explore therapeutic potentials and future opportunities for research. Information on studies of the genus Peganum was gathered via the Internet (using Google Scholar, Baidu Scholar, Elsevier, ACS, Pudmed, Web of Science, CNKI and EMBASE) and libraries. Additionally, information was also obtained from some local books, PhD and MS's dissertations. The genus Peganum has played an important role in traditional Chinese medicine. The main bioactive metabolites of the genus include alkaloids, flavonoids, volatile oils, etc. Scientific studies on extracts and formulations revealed a wide range of pharmacological activities, such as cholinesterase and monoamine oxidase inhibitory activities, antitumor, anti-hypertension, anticoagulant, antidiabetic, antimicrobial, insecticidal, antiparasidal, anti-leishmaniasis, antioxidant, and anti-inflammatory. Based on this review, there is some evidence for extracts' pharmacological effects on Alzheimer's and Parkinson's diseases, cancer, diabetes, hypertension. Some indications from ethnomedicine have been confirmed by pharmacological effects, such as the cholinesterase, monoamine oxidase and DNA topoisomerase inhibitory activities, hypoglycemic and vasodilation effects of this genus. The available literature showed that most of the activities of the genus Peganum can be attributed to the active alkaloids. Data regarding many aspects of the genus such as mechanisms of actions, metabolism, pharmacokinetics, toxicology, potential drug interactions with standard-of-care medications is still limited which call for additional studies particularly in humans. Further assessments and clinical trials should be performed before it can be integrated into medicinal practices. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

The processed lateral root of Aconitum carmichaelii Debeaux (Ranunculaceae), an extensively used traditional Chinese medicine, is known as Fuzi in China (Chinese: ), "bushi" in Japan, "Kyeong-Po Buja" in Korea, Chinese aconite, monkshood or Chinese wolfsbane. It has been used to treat shock resulting from acute myocardial infarction, low blood pressure, coronary heart disease, chronic heart failure, etc. The present paper aims to provide an up-to-date review at the advancements of the investigations on the ethnopharmacology, phytochemistry, pharmacological effect and toxicity of Fuzi. Besides, the possible tendency and perspective for future research of this plant are discussed, as well. All available information on Fuzi was collected via electronic search (using Elsevier, PubMed, ACS, CNKI, Google Scholar, Baidu Scholar, and Web of Science), books and classic works about Chinese herb. 122 chemical constituents, among which C19-diterpenoid alkaloids and C20-diterpenoid alkaloids are the predominant groups, have been isolated and identified from Fuzi. Fuzi with its active compounds is possessed of wide-reaching biological activities, including effects on cardiovascular system, anti-inflammation and analgesic action, anti-tumor activity, effect on the immune system, hypoglycemic and hypolipidemic effects, anti-aging effect, effect of protecting kidney and effect on energy metabolism. Nearly all of compounds were found from the roots of the plant, so further phytochemical studies should focus more on the other parts of the plant, such as the leaves, flowers or stems. Besides, a majority of the pharmacological studies were carried out using crude and poorly characterized extracts. Thus, more bioactive components particularly cardiotonic and analgesic compounds should be identified through bioactivity-guided isolation strategies. Moreover, investigations on how to develop Fuzi׳s new clinical usage on the basis of its pharmacological effects are in requirement. Copyright © 2014. Published by Elsevier Ireland Ltd.

In the genus Gelsemium, Gelsemium elegans (Gardn. & Champ.) Benth. has been recognized as a toxic plant that is widely distributed in Southeast Asia and has been used as traditional Chinese medicine for the treatment of rheumatoid pain, neuropathic pain, spasticity, skin ulcers and cancers for many years. Gelsemium sempervirens (L.) J.St.-Hil. has been used since the nineteenth century in homeopathy for treating anxiety, neuralgia, migraine and spasmodic disorders, such as asthma and whooping cough in North America. This review aims to provide comprehensive information on the botany, traditional uses, phytochemistry, pharmacological research and toxicology of medicinal plants in the genus Gelsemium. The overall objective is to explore the evidence supporting its ethnopharmacological effectiveness. A literature survey was performed by searching the scientific databases Pubmed, Google Scholar, SciFinder, Scopus, Web of Science and the Chinese CNKI, in addition to traditional Chinese medicine and homeopathic texts for information on Gelsemium. Plants of the genus Gelsemium have been used in traditional medicine for the treatment of migraines, neuralgia, sciatica, cancer and various types of sores. Studies into the phytochemical composition of this genus have shown that all of the species are rich sources of monoterpene indole alkaloids and that they have attracted the attention of many researchers due to their markedly diverse and complex architecture. To date, a total of 121 alkaloids have been isolated and identified from the genus. The crude extracts, as well as the monomeric compounds, from the genus possess anti-tumor, analgesic, anxiolytic, anti-inflammatory and immunomodulating pharmacological activities. It is evident from the available literature that Gelsemium species possess potential for use as a beneficial therapeutic remedy. However, the analysis of previous pharmacological research suggests that a clear assignment of active molecules and mechanisms of action is remain lacking. Due to their high toxicity, the studies available on toxicity and safety are inadequate for providing information on clinical utilization. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Plants of the genus Desmodium (Fabaceae), such as Desmodium styracifolium (Osbeck) Merr. and Desmodium gyrans (L. f.) DC., have a long history of medical use in Traditional Chinese Medicine to treat various ailments including rheumatism, pyrexia, dysentery, wounds, cough, malaria, hepatitis, hemoptysis, etc. In the theory of Traditional Chinese Medicine, most species have the effect of relieving internal heat or fever, neutralizing toxins, inhibiting pain, invigorating blood circulation, suppressing cough and alleviating dyspnea. A bibliographic investigation was accomplished by analyzing secondary sources including Chinese Herbal Classics, and worldwide accepted scientific databases (Pubmed, Scopus and Web of Science, SciFinder) were scrutinized for the available information on the ethnopharmacological uses in Chinese medicine, phytochemistry, pharmacology and toxicology of Desmodium species. The genus Desmodium is a large member of the Papilionaceae (Fabaceae) family. It contains about 350 plant species used for both feeding stuffs and herbal medicines, of which only about 30 species have been phytochemically or pharmacologically investigated. Desmodium plant extracts, as well as the active principles, have been experimentally studied for their anti-inflammatory, cytotoxic, antidiabetic, antinephrolithic, antibacterial, and nootropic activities in vitro or in vivo. And so far, a total of 212 compounds have been isolated from 15 Desmodium species and characterized mainly as flavonoids and alkaloids, followed by terpenoids, steroids, phenols, phenylpropanoids, glycosides and a number of volatile oils. The remaining unrevealed species are recorded chiefly in Asia and Africa being used in empirical treatment for various diseases. Desmodium species have long been used in TCM to treat various ailments. Available scientific references revealed that the traditional medical uses of some important Desmodium species in TCM have been evaluated by modern pharmacological studies. As literature demonstrated, flavonoids and alkaloids are perhaps responsible for most of the activities shown by the plants of this genus. Further studies are still required to reveal the structure-activity relationship of these active constituents. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Administration in the social field is examined based on an analysis of its practices, the rationalist myth and its ideological dimensions. In this way, the article discusses the most frequently utilized concepts (administration, management, gerencia, gestión) and their etymologies; the limitations of teaching administration; the complexity of a practice marked by the dimensions of science, art and the social game; and the ideological question underlying the great thought factory that the general theory of administration has been since the start of the 19th century. The article reflects upon the need to construct a theory based in practice contextualized in the global south that goes beyond the classic frames of reference and, above all, to transform administration into a problem to be discussed outside of the knowledge that recognizes it as a technical practice.

Sexuality as to its etymology presupposes the duality of sexes. Using quantitative neuroimaging meta-analyses, we demonstrate robust sex differences in the neural processing of sexual stimuli in thalamus, hypothalamus, and basal ganglia. In a narrative review, we show how these relate to the well-established sex differences on the behavioral level. More specifically, we describe the neural bases of known poor agreement between self-reported and genital measures of female sexual arousal, of previously proposed male proneness to affective sexual conditioning, as well as hints of unconscious activation of bonding mechanisms during sexual stimulation in women. In summary, our meta-analytic review demonstrates that neurofunctional sex differences during sexual stimulation can account for well-established sex differences in sexual behavior. PMID:27742561

Wombs, Worms and Wolves: Constructing Cancer in Early Modern England.

PubMed

Skuse, Alanna

2014-11-01

This essay examines medical and popular attitudes to cancer in the early modern period, c .1580-1720. Cancer, it is argued, was understood as a cruel and usually incurable disease, diagnosable by a well-defined set of symptoms understood to correspond to its etymological root, karkinos (the crab). It was primarily understood as produced by an imbalance of the humours, with women being particularly vulnerable. However, such explanations proved inadequate to make sense of the condition's malignancy, and medical writers frequently constructed cancer as quasi-sentient, zoomorphising the disease as an eating worm or wolf. In turn, these constructions materially influenced medical practice, in which practitioners swung between anxiety over 'aggravating' the disease and an adversarial approach which fostered the use of radical and dangerous 'cures' including caustics and surgery.

The Curious Connection Between Insects and Dreams.

Klein, Barrett A

2011-12-21

A majority of humans spend their waking hours surrounded by insects, so it should be no surprise that insects also appear in humans' dreams as we sleep. Dreaming about insects has a peculiar history, marked by our desire to explain a dream's significance and by the tactic of evoking emotions by injecting insects in dream-related works of art, film, music, and literature. I surveyed a scattered literature for examples of insects in dreams, first from the practices of dream interpretation, psychiatry, and scientific study, then from fictional writings and popular culture, and finally in the etymology of entomology by highlighting insects with dream-inspired Latinate names. A wealth of insects in dreams, as documented clinically and culturally, attests to the perceived relevance of dreams and to the ubiquity of insects in our lives.

Vieira, A.

2010-01-01

Background: In relation to pharmacognosy, an objective of many ethnobotanical studies is to identify plant species to be further investigated, for example, tested in disease models related to the ethnomedicinal application. To further warrant such testing, research evidence for medicinal applications of these plants (or of their major phytochemical constituents and metabolic derivatives) is typically analyzed in biomedical databases. Methods: As a model of this process, the current report presents novel information regarding traditional anti-inflammation and anti-infection medicinal plant use. This information was obtained from an interview-based ethnobotanical study; and was compared with current biomedical evidence using the Medline® database. Results: Of the 8 anti-infection plant species identified in the ethnobotanical study, 7 have related activities reported in the database; and of the 6 anti-inflammation plants, 4 have related activities in the database. Conclusion: Based on novel and complimentary results from the ethnobotanical and biomedical database analyses, it is suggested that some of these plants warrant additional investigation of potential anti-inflammatory or anti-infection activities in related disease models, and also additional studies in other population groups.

The present study aimed to assess the quality and risks involved in the consumption of psychoactive herbal products (PHs) that are available through informal commerce in the city of Diadema, SP, Brazil. Methods of ethnography were used to conduct the fieldwork during which four dealers were selected to record the collection, handling, packaging, types of PHs marketed, and their therapeutic purposes. In addition, lots of the PHs selected were purchased from the dealers and analyzed using microbiology and pharmacognosy techniques. 217 PHs were recorded and categorized into two main groups: stimulants (67%) and depressants (27%) of the central nervous system; sixteen of them were selected, and their 52 lots were acquired. The deficiencies observed in handling and packaging these lots by dealers were confirmed by microbiological analysis; 80.8% of them presented risk according to the indicators defined by the Brazilian Pharmacopoeia. The pharmacognostic analysis confirmed the authenticity of only 9 to 16 PHs analyzed. In addition, descriptions of contraindications, adverse reactions, and drug interactions were found in the literature for the PHs. The results of this study allow the observation of the priorities for the sanitary adequacy of the popular trade of herbs. PMID:23818934

Kampo-medicine has become popular in Japanese medical practice combined with western medicine. For example, Daikenchu-To for intestinal obstruction after surgical operation, Shakuyakukanzo-To and Goshajinki-Gan for anti-cancer agents-induced neuropathy, and Yokkan-San for behavioral psychological symptoms of dementia are alternatively used in addition to conventional treatments in Japan. However, combined use of Kampo-medicine and western medicine may cause unexpected adverse events including undesirable drug-drug interactions because Kampo-medicine was not originally developed to be used with western medicine. Although adverse effects of Kampo-medicine are rare compared with those of western medicine, severe events such as liver dysfunction and interstitial pneumonia have been reported in increasing trends. Medical staff including pharmacists, therefore, should be aware of the onset of adverse events before the patients' symptoms become severe. Several adverse effects are caused by chemical constituents such as glycyrrhizin in licorice for pseudoaldosteronism and geniposide in Gardeniae fructus for mesenteric phlebosclerosis. To understand the adverse effects of Kampo-medicine, pharmacists should learn trends in current medication as well as pharmacology and toxicology of the chemical constituents in pharmacognosy. These issues should also be addressed in educational materials for students of clinical pharmacy and pharmacy practice.

Russo, Ethan B

2016-07-01

Plants have been the predominant source of medicines throughout the vast majority of human history, and remain so today outside of industrialized societies. One of the most versatile in terms of its phytochemistry is cannabis, whose investigation has led directly to the discovery of a unique and widespread homeostatic physiological regulator, the endocannabinoid system. While it had been the conventional wisdom until recently that only cannabis harbored active agents affecting the endocannabinoid system, in recent decades the search has widened and identified numerous additional plants whose components stimulate, antagonize, or modulate different aspects of this system. These include common foodstuffs, herbs, spices, and more exotic ingredients: kava, chocolate, black pepper, and many others that are examined in this review. Copyright © 2016 Elsevier Ltd.

The Doctrine of Signatures, Materia Medica of Orchids, and the Contributions of Doctor - Orchidologists.

PubMed

Pearn, John

2012-12-01

The heritage of medicine is written in many forms. One repository is to be found in the history of orchids, the world's largest family of flowering plants. Orchids were so named by Theophrastus (c.372-288 BC) who recorded their medicinal use as an aphrodisiac and the promoter of virility, in the context of the Doctrine of Signatures. Such use endured for millennia, and was recorded both by Paracelsus (1493-1551) and Linnaeus (1707-1778). The history of orchidology and medicine are entwined in four domains: (a) orchids and their historical materia medica, within the paradigm of the Doctrine of Signatures; (b) the enduring and extensive contemporary medicinal and culinary use of orchids such as Vanilla and salep extracts of Orchis; (c) the scientific contributions of doctors as orchidologists; and (d) the heritage of more than a hundred doctors' names in the scientific etymology of the Orchidaceae family. Prominent orchidologists have included the Scottish doctor-soldier and botanist, Robert Brown (1773-1858); the Director of the State Herbarium at Leyden and the Rijks Museum, Carl Ludwig Blume (1796-1862); and Dr William Sterling MD (1888-1967). Among the more than 1250 genus names (and 33,000 species) of orchids are the names of more than a hundred doctors, their lives and works perpetuated in the scientific etymology of this family of exotic, beautiful, flamboyant, intriguing and often expensive flowers. Generic names record the lives and works of such as Aristotle (384-322BC) in Aristotelia Loureiro 1790; Cadet de Gassicourt (1769-1821) in Cadetia Gaudichaud 1826; Sir Joseph Dalton Hooker (1817-1911) in Sirhookera O. Kuntze 1891; and Dr Theodore Daniel Vrydag Zynen (fl. 1820-1850) in Vrydagzynea Blume 1858. One of the principal horticultural genera of orchids, Brassavola, records the life and work of the Ferrara and Padua physician and botanist, Antonio Musa Brassavola (1500-1555). The first Slipper Orchid bred as a hybrid, Paphiopedilum harrisianum (by John Dominy [1816-1892], at Exeter in England) was named after his colleague, the Devon surgeon, Dr John Harris (1782-1855).

Elia, J P

1987-01-01

This article examines the attitudes toward male masturbation in the ancient western world. More specifically, this work deals with ancient Egypt, Greece, and Rome. By comparing each epoch and geographic region, intolerance of autoerotic activity can be seen. Although there is a pattern of intolerance, the act of masturbation is always viewed provisionally. In addition, by examining these three periods of history not only can attitudes be scrutinized, but also it can be seen quite clearly that there was no golden age of sexuality: The attitude of accepted and encouraged unlimited and varied sexual practices does not exist in the ancient western world. As in many other cultures in various stages of history, procreative sexuality is the dominating theme. Thus, current attitudes of sex are derived from, and still survive due to the influence of, ancient western civilization.

Many investigators have described the anatomy of the volar retinacular structures of the hand over the last 60 years. As a result, multiple terms have been assigned to 1 anatomical structure and 1 name designated to more than 1 structure. Our purpose is to review the detailed anatomy and key components of the volar retinacular elements of the hand, their etymology, and their most recent descriptions. The objective also is to organize these structures into systems, which can be helpful for learners to assimilate into a practical anatomical guide. Lastly, the goal is to create a common nomenclature for identifying the volar retinacular structures of the hand in order to facilitate clear communication about them across languages.

Wombs, Worms and Wolves: Constructing Cancer in Early Modern England

PubMed Central

Skuse, Alanna

2014-01-01

This essay examines medical and popular attitudes to cancer in the early modern period, c.1580–1720. Cancer, it is argued, was understood as a cruel and usually incurable disease, diagnosable by a well-defined set of symptoms understood to correspond to its etymological root, karkinos (the crab). It was primarily understood as produced by an imbalance of the humours, with women being particularly vulnerable. However, such explanations proved inadequate to make sense of the condition's malignancy, and medical writers frequently constructed cancer as quasi-sentient, zoomorphising the disease as an eating worm or wolf. In turn, these constructions materially influenced medical practice, in which practitioners swung between anxiety over ‘aggravating’ the disease and an adversarial approach which fostered the use of radical and dangerous ‘cures’ including caustics and surgery.

The plant is use traditionally as a remedy for numerous disease such as use wounds healing, rheumatism, psoriasis, diarrhea and stomach ailments. It is also use as an aphrodisiac and for skin care. The present review aims to compile an up-to-date review of the progress made in the continuous pharmacological and phytochemistry investigation of K. africana and the corresponding commercial and pharmaceutical application of these findings with the ultimate objective of providing a guide for future research on this plant. The scholarly information needed for this paper were predominantly sourced from the electronic search engines such as Google, Google scholar; publishing sites such as Elsevier, scienceDirect, BMC, PubMed; other scientific database sites for chemicals such as ChemSpider, PubChem, and also from online books. Pharmacological investigations conducted confirm the anti-inflammatory, analgesic, antioxidant and anticancer activity of the extract of different parts of the plant. Bioactive constituents are found to be present in all parts of the plant. So far, approximately 150 compounds have been characterized from different part of the plant. Iridoids, naphthoquinones, flavonoids, terpenes and phenylethanoglycosides are the major class of compounds isolated. Novel compounds with potent antioxidant, antimicrobial and anticancer effect such as verbascoside, verminoside and pinnatal among others, have been identified. Commercial trade of K. africana has boosted in the las few decades. Its effect in the maintenance of skin has been recognized resulting in a handful of skin formulations in the market. The pharmaceutical potentials of K. africana has been recognized and have witness a surge in research interest. However, till date, many of its traditional medicinal uses has not been investigated scientifically. Further probing of the existential researches on its pharmacological activity is recommended with the end-goal of unravelling the pharmacodynamics, pharmacokinetics, clinical relevance and possible toxicity and side effects of both the extract and the active ingredients isolated.

The genus Uncaria belongs to the family Rubiaceae, which mainly distributed in tropical regions, such as Southeast Asia, Africa and Southeast America. Their leaves and hooks have long been thought to have healing powers and are already being tested as a treatment for asthma, cancer, cirrhosis, diabetes, hypertension, stroke and rheumatism. The present review aims to provide systematically reorganized information on the ethnopharmacology, phytochemistry and pharmacology of the genus Uncaria to support for further therapeutic potential of this genus. To better understanding this genus, information on the stereo-chemistry and structure-activity relationships in indole alkaloids is also represented. The literature study of this review is based on various databases search (SCIFinder, Science Direct, CNKI, Wiley online library, Spring Link, Web of Science, PubMed, Wanfang Data, Medalink, Google scholar, ACS, Tropicos, Council of Heads of Australasian Herbaria, The New York Botanical Garden, African Plants Database at Genera Botanical Garden, The Plant List and SEINet) and library search for Biological Abstract and some local books on ethnopharmacology. 19 species of the genus Uncaria are found to be important folk medicines in China, Malaysia, Phillippines, Africa and Southeast America, etc, and have been served for the treatment of asthma, rheumatism, hyperpyrexia, hypertension and headaches, etc. More than 200 compounds have been isolated from Uncaria, including indole alkaloids, triterpenes, flavonoids, phenols, phenylpropanoids, etc. As characteristic constituents, indole alkaloids have been considered as main efficacy component for hypertension, epilepsy, depressant, Parkinson's disease and Alzheimer's disease. In addition, pharmacokinetic and metabolism investigation reveal that the indole alkaloids are likely to be absorbed, metabolized and excreted at early time points. Moreover, the specific inhibition of CYP isozymes can regulate their hydroxylation metabolites at C-10 and C-11. Preliminary investigations on pharmacological properties of the Uncaria species have enlightened their efficacious remedy for hypertension, asthma, cancer, diabetes, rheumatism and neurodegenerative diseases. To ensure the safety and effectiveness in clinical application, research on bioactive compounds, pharmacological mechanisms and toxicity of the genus Uncaria as well as the stereo-chemistry and structure-activity relationships of indole alkaloids seem very important.

The genus Litsea is one of the most diverse genera of evergreen trees or shrubs belong to Lauraceae, and comprises roughly 400 species of tree that are distributed abundantly throughout tropical and subtropical Asia, North and South America. Litsea species have been used globally in traditional medicine for the treatment of various diseases including influenza, stomach aches, diarrhea, diabetes, vomiting, bone pain, inflammation, illness related to the central nervous system and other ailments. The purpose of this review is to provide updated, comprehensive and categorized information on the ethnobotany, phytochemistry and pharmacological research of Litsea species in order to explore their therapeutic potential and evaluate future research opportunities. All the available information on Litsea species was actualised by systematically searching the scientific literatures including Chinese, Korean, Japanese, Indian, and South American herbal classics, library catalogs and scientific databases (PubMed, SciFinder, Web of Science, Google Scholar, VIP and Wanfang). The Plant List, International Plant Name index and Scientific Database of China Plant Species were used to validate scientific names. 407 secondary metabolites have been reported from Litsea species. Litsea Species are sources of secondary metabolites with interesting chemical structures (alkaloids, lactones, sesquiterpenes, flavonoids, lignans, and essential oils) and significant bioactivities. Crude extracts, fractions and phytochemical constituents isolated from Litsea show a wide spectrum of in vitro and in vivo pharmacological activities including anticancer, anti-inflammatory, antimicrobial, antioxidant, antidiabetic, anti-HIV, insecticidal, etc. From data collected in this review, the genus Litsea comprises a wide range of therapeutically promising and valuable plants, and has attracted much attention owing to its multiple functions. Many traditional uses of Litsea species have now been validated by modern pharmacology research. Deep and systematic phytochemical investigation of the genus Litsea and the pharmacological properties, especially its mechanism of action and toxicology, to illustrate its ethnomedicinal use, explore the therapeutic potential and support further health-care product development will undoubtedly be the focus of further research. Therefore, detailed and extensive studies and clinical evaluation of Litsea species should be carried out in future for the safety approval of therapeutic applications.

Calotropis gigantiea (L.) R. Br (Apocynaceae) commonly called as "crown flower" or "giant milk weed" is a well-known weed to many cultures for treating various disorders related to central nervous system, skin diseases, digestive system, respiratory system, reproductive system etc. Indigenous groups made the plant as a part of their lives since they use the fruit fibre to make ropes, household items, for weaving clothes and flowers for garlands apart from usage for various indications. The study aims at far-reaching review on phytochemistry, pharmacological activities, ethnopharmacology, intellectual property transfer on pharmacological therapies, toxicity which aids to provide scientific evidence for the ethnobotanical claims and to identify gaps required to be conducted as a future research prerequisite. A systematic literature search was performed using different databases such as Scopus, Science direct, PubMed and Sciverse with no timeline limit set during the search. All the available abstracts and full text articles were included in the systematic review. Most of the folkloric uses were validated by the scientific studies such as analgesic, anti-arthritic, anti-asthmatic, anti-bacterial, anti-convulsant, anti-pyretic, central nervous system disorders, contraceptive, anti-ulcer and wound healing. In addition other studies such as anti-diabetic, anti-diarrhoeal, anti-helminthic, anti-histamine, anti-inflammatory, anti-microbial, anti-oxidant, cardio-protective studies, cytotoxicity, hepatoprotectivity, fibrinolytic, mosquitocidal, nerve muscle activity, vasodilation and skeletal muscle activities were also reported for the plant. Isolated compounds such as calotropin, frugoside and 4'-O-β-D-glucopyranosyl frugoside were tested for the cytotoxicity efficacy against both human and rat cell lines out of which calotropin showed potent activity (IC50-15 ng/ml). However there were no clinical trials reported on the plant which is one of the major lacunas. This review article explores the ethnopharmacological, pharmacological activities phytochemistry and intellectual rights of Cg which gives the evidence of a potent and commercial drug which up on further research leads to the most viable drug for variety of treatments. However there is further need for in-vivo studies and clinical trials on isolated phytoconstituents which will help to commercialise. © 2013 Published by Elsevier Ireland Ltd.

Polygonum cuspidatum Sieb. et Zucc. (Polygonum cuspidatum), also known as Reynoutria japonica Houtt and Huzhang in China, is a traditional and popular Chinese medicinal herb. Polygonum cuspidatum with a wide spectrum of pharmacological effects has been used for treatment of inflammation, favus, jaundice, scald, and hyperlipemia, etc. The present paper reviews the traditional applications as well as advances in botany, phytochemistry, pharmacodynamics, pharmacokinetics and toxicology of this plant. Finally, the tendency and perspective for future investigation of this plant are discussed, too. A systematic review of literature about Polygonum cuspidatum is carried out using resources including classic books about Chinese herbal medicine, and scientific databases including Pubmed, SciFinder, Scopus, the Web of Science and others. Polygonum cuspidatum is widely distributed in the world and has been used as a traditional medicine for a long history in China. Over 67 compounds including quinones, stilbenes, flavonoids, counmarins and ligans have been isolated and identified from this plant. The root of this plant is used as the effective agent in pre-clinical and clinical practice for regulating lipids, anti-endotoxic shock, anti-infection and anti-inflammation, anti-cancer and other diseases in China and Japan. As an important traditional Chinese medicine, Polygonum cuspidatum has been used for treatment of hyperlipemia, inflammation, infection and cancer, etc. Because there is no enough systemic data about the chemical constituents and their pharmacological effects or toxicities, it is important to investigate the pharmacological effects and molecular mechanisms of this plant based on modern realization of diseases' pathophysiology. Drug target-guided and bioactivity-guided isolation and purification of the chemical constituents from this plant and subsequent evaluation of their pharmacologic effects will promote the development of new drug and make sure which chemical constituent or multiple ingredients contributes its pharmacological effects. Additionally, chemicals and their pharmacological effects of the other parts such as the aerial part of this plant should be exploited in order to avoid resource waste and find new chemical constituents.

Crataegus macracantha Lodd, family Rosaceae, is a very rare species in Europe, and unlike Crataegus monogyna is less investigated for pharmacologic activity. To analyze the ability of the lyophilisate of extract obtained from leaves of Crataegus macracantha Lodd (single plant at the Iaşi Botanical Garden) to capture free radicals in vitro. The lyophilisate obtained in Department of Pharmacognosy, Faculty of Pharmacy, "Grigore T. Popa" University of Medicine and Pharmacy Iaşi. The decreased absorbance of chromophore chlorpromazine radical cation in the presence of the lyophilized solutions was studied spectrophotometrically. The indicator radical cation, obtained by oxidation of chlorpromazine by potassium persulfate, has the maximum absorbance at 525 nm. Ascorbic acid was used as a standard antioxidant. The absorbance of radical solution was determined after the addition of a certain amount of lyophilisate at different time intervals. The antioxidant activity was calculated using the calibration curve obtained by plotting the variation in radical solution absorbance depending on ascorbic acid concentration. For each ascorbic acid concentration the area under the curve was calculated from plotting the percentage inhibition of the absorbance at two pre-established time intervals. The results confirm the antioxidant activity of the leaves of Crataegus Macracantha Lodd and by optimizing the proposed analytical methods the antiradical activity can be quickly evaluated with minimal reagent consumption.

In 1999, the Department of Medicinal Chemistry and Pharmacognosy at the College of Pharmacy, University of Illinois (UIC) at Chicago was funded to establish a Botanical Dietary Supplements Research Center from the National Institutes of Health (NIH). The emphasis of the UIC/NIH Center for Botanical Dietary Supplements Research (CBDSR) is botanical dietary supplements (BDS) for women's health. Center’s research has focused on BDS that may improve women's health and quality of life, specifically in the areas of menopause, premenstrual syndrome, and persistent urinary tract infections. Center investigators have overcome many challenges associated with botanical dietary supplements research, including acquiring and identifying plant species for investigation, isolating and identifying active constituents, elucidating the mechanisms of action of these botanicals, and conducting phase I and phase II clinical studies. Black cohosh [Actaea racemosa L. (Ranunculaceae)] has been used as a model to illustrate the steps involved in taking a botanical dietary supplement from the field, all the way to clinical trials. Bioassays are described that were necessary to elucidate the pertinent biological studies of plant extracts and their mechanisms of action. The Center has used an innovative multidisciplinary approach to this type of research, and thus has been very successful in fulfilling its specific aims. PMID:20161501

Aptekari (pharmacists) act as responsible pharmacists, pharmacy owners, and managers. They follow a five year Masters of Science in Pharmacy (M.Sc. Pharm.) degree course with a six month traineeship. Pomoshnik-farmacevti (assistant pharmacists) follow a three year degree with a six month traineeship. They can prepare medicines and dispense OTC medicines under the supervision of a pharmacist. The first and second year of the M.Sc. Pharm. degree are devoted to chemical sciences, mathematics, botany and medical sciences. Years three and four center on pharmaceutical technology, pharmacology, pharmacognosy, pharmaco-economics, and social pharmacy, while year five focuses on pharmaceutical care, patient counselling, pharmacotherapy, and medical sciences. A six month traineeship finishes the fifth year together with redaction of a master thesis, and the four state examinations with which university studies end. Industrial pharmacy and clinical (hospital) pharmacy practice are integrated disciplines in some Bulgarian higher education institutions such as the Faculty of Pharmacy of the Medical University of Sofia.

 A variety of chemicals produced by plants, often referred to as 'phytochemicals', have been used as medicines, food, fuels and industrial raw materials. Recent advances in the study of genomics and metabolomics in plant science have accelerated our understanding of the mechanisms, regulation and evolution of the biosynthesis of specialized plant products. We can now address such questions as how the metabolomic diversity of plants is originated at the levels of genome, and how we should apply this knowledge to drug discovery, industry and agriculture. Our research group has focused on metabolomics-based functional genomics over the last 15 years and we have developed a new research area called 'Phytochemical Genomics'. In this review, the development of a research platform for plant metabolomics is discussed first, to provide a better understanding of the chemical diversity of plants. Then, representative applications of metabolomics to functional genomics in a model plant, Arabidopsis thaliana, are described. The extension of integrated multi-omics analyses to non-model specialized plants, e.g., medicinal plants, is presented, including the identification of novel genes, metabolites and networks for the biosynthesis of flavonoids, alkaloids, sulfur-containing metabolites and terpenoids. Further, functional genomics studies on a variety of medicinal plants is presented. I also discuss future trends in pharmacognosy and related sciences.

The historical origins of the vegetative state: Received wisdom and the utility of the text.

PubMed

Adams, Zoe M; Fins, Joseph J

2017-01-01

The persistent vegetative state (PVS) is one of the most iconic and misunderstood phrases in clinical neuroscience. Coined as a diagnostic category by Scottish neurosurgeon Bryan Jennett and American neurologist Fred Plum in 1972, the phrase "vegetative" first appeared in Aristotle's treatise On the Soul (circa mid-fourth century BCE). Aristotle influenced neuroscientists of the nineteenth and early-twentieth centuries, Xavier Bichat and Walter Timme, and informed their conceptions of the vegetative nervous system. Plum credits Bichat and Timme in his use of the phrase, thus putting the ancient and modern in dialogue. In addition to exploring Aristotle's definition of the "vegetative" in the original Greek, we put Aristotle in conversation with his contemporaries-Plato and the Hippocratics-to better apprehend theories of mind and consciousness in antiquity. Utilizing the discipline of reception studies in classics scholarship, we demonstrate the importance of etymology and historical origin when considering modern medical nosology.

The existence of acquired cholesteatoma has been recognized for more than three centuries; however, the nature of the disorder has yet to be determined. Without timely detection and intervention, cholesteatomas can become dangerously large and invade intratemporal structures, resulting in numerous intra- and extracranial complications. Due to its aggressive growth, invasive nature, and the potentially fatal consequences of intracranial complications, acquired cholesteatoma remains a cause of morbidity and death for those who lack access to advanced medical care. Currently, no viable nonsurgical therapies are available. Developing an effective management strategy for this disorder will require a comprehensive understanding of past progress and recent advances. This paper presents a brief review of background issues related to acquired middle ear cholesteatoma and deals with practical considerations regarding the history and etymology of the disorder. We also consider issues related to the classification, epidemiology, histopathology, clinical presentation, and complications of acquired cholesteatoma and examine current diagnosis and management strategies in detail.

Flexural eczema versus atopic dermatitis.

PubMed

Jacob, Sharon E; Goldenberg, Alina; Nedorost, Susan; Thyssen, Jacob P; Fonacier, Luz; Spiewak, Radoslaw

2015-01-01

Flexural eczema and atopic dermatitis are frequently synonymized. As respiratory atopy is rarely tested for and found in these patients, systematically equating a flexural distribution of dermatitis with atopic dermatitis may too frequently result in misclassified diagnoses and potentially missed opportunity for intervention toward improving patients' symptoms and quality of life. We present a critical review of the available evidence for the atopic dermatitis diagnosis and discuss the similarities between atopic dermatitis and allergic contact dermatitis. Because neither flexural predilection nor atopy is specific for atopic dermatitis, we conclude that the term atopic dermatitis is a misnomer and propose an etymologic reclassification of atopic dermatitis to "atopy-related" dermatitis. Allergic contact dermatitis can induce an atopic dermatitis-like phenotype, and thus, flexural dermatitis cannot be assumed as atopic without further testing. Patch testing should at least be considered in cases of chronic or recurrent eczema regardless of the working diagnosis.

History of plastic surgery: Art, philosophy, and rhinoplasty.

PubMed

Macionis, Valdas

2018-03-23

The 200th anniversary of K. F. Graefe's "Rhinoplasty," E. Zeis' naming of the specialty of plastic surgery in 1838, and the continuing discussion on what is plastic surgery have prompted this historical-conceptual review with a semantic insight into the meaning of the word "plastic." A literature search has revealed that this term contains dual aspects: artistic and philosophical. The progressive development of these two connotations can be traced from their origin in the ceramics and the myths of ancient Greeks to their metamorphoses in fine arts, science, and philosophy of plasticity of the modern day. Although the names of plastic procedures and the title of the specialty carry both the artistic and philosophical features, the philosophical notion is less evident. This article underlines the importance of etymology in the interpretation of the concept of plastic surgery. Copyright © 2018 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

The miswak is a natural toothbrush made from the twigs of the Salvadora persica (Salvadoraceae). Its use predates the inception of Islam and is frequently advocated in the Hadith (the traditions relating to the life of Prophet MuhammadPBUH). In addition to strengthening the gums, it prevents tooth decay, eliminating toothaches and halt further increase in decay that has already set in. It creates a fragrance in the mouth, eliminates bad odor, improves the sense of taste, and causes the teeth to glow and shine. The other parts of the tree have therapeutic values as corrective, deobstruent, liver tonic, diuretic, analgesic, anthelmintic, astringent, lithontriptic, carminative, diuretic, aphrodisiac, and stomachic. The present review is therefore an effort to give detailed survey of the literature on phytochemistry and pharmacological activities of miswak. PMID:21430961

Ginger is a commonly used spice and herbal medicine worldwide. Besides its extensive use as a condiment, ginger has been used in traditional Chinese medicine for the management of various medical conditions. In recent years, ginger has received wide attention due to its observed antiemetic and anticancer activities. This paper reviews the potential role of ginger and its active constituents in cancer chemoprevention. The phytochemistry, bioactivity, and molecular targets of ginger constituents, especially 6-shogaol, are discussed. The content of 6-shogaol is very low in fresh ginger, but significantly higher after steaming. With reported anti-cancer activities, 6-shogaol can be served as a lead compound for new drug discovery. The lead compound derivative synthesis, bioactivity evaluation, and computational docking provide a promising opportunity to identify novel anticancer compounds originating from ginger.

2014-01-01

Plants belonging to the genus Veratrum have been used throughout history for their medicinal properties. During the nineteenth and twentieth centuries, phytochemical investigations revealed a host of steroidal alkaloids in Veratrum species, some of which are potent bioactives. This review discusses Veratrum species that grow in North America with a focus on the medicinal history of these plants and the steroidal alkaloids they contain. While significant reviews have been devoted to singularly describing the plant species within the genus Veratrum (botany), the staggering breadth of alkaloids isolated from these and related plants (phytochemistry), and the intricacies of how the various alkaloids act on their biological targets (physiology and biochemistry), this review will straddle the margins of the aforementioned disciplines in an attempt to provide a unified, coherent picture of the Veratrum plants of North America and the medicinal uses of their bioactive steroidal alkaloids.

Natural products frequently exert pharmacological activities. The present review gives an overview of the ethnobotany, phytochemistry and pharmacology of the Cedrus genus, e.g. cytotoxic, spasmolytic immunomodulatory, antiallergic, anti-inflammatory and analgesic activities. Cancer patients frequently seek remedies from traditional medicinal plants that are believed to exert less side effects than conventional therapy with synthetic drugs. A long-lasting goal of anti-cancer and anti-microbial therapy research is to find compounds with reduced side effects compared to currently approved drugs. In this respect, Cedrus species might be of interest. The essential oil isolated from Cedrus libani leaves may bear potential for drug development due to its high concentrations of germacrene D and β-caryophyllene. The essential oils from Cedrus species also show bioactivity against bacteria and viruses. More preclinical analyses (e.g. in vivo experiments) as well as clinical trials are required to evaluate the potential of essential oils from Cedrus species for drug development.

Goose grass also known as Eleusine indica (EI) is a local medicinal plant that displays antioxidant, antimicrobial and anticancer activities. The present study is to determine the phytochemical constituents, cytotoxicity and antiviral activities for both crude extract and fraction obtained from the plant. The crude extract contained more secondary metabolites compared to the hexane fraction as gauged using standard phytochemical tests. Cytotoxicity screening against Vero cells using MTT assay showed that the CC50 values for crude extract and hexane fraction were 2.07 and 5.62 mg/ml respectively. The antiviral activity towards Herpes Simplex Virus type 1 (HSV-1) was determined using plaque reduction assay. The selective indices (SI = CC50 / EC50) for both methanol extract and hexane fraction were 12.2 and 6.2 respectively. These results demonstrate that the extract prepared from E. indica possesses phytochemical compound that was non cytotoxic to the cell with potential antiviral activity.

Can Invalid Bioactives Undermine Natural Product-Based Drug Discovery?

PubMed Central

2015-01-01

High-throughput biology has contributed a wealth of data on chemicals, including natural products (NPs). Recently, attention was drawn to certain, predominantly synthetic, compounds that are responsible for disproportionate percentages of hits but are false actives. Spurious bioassay interference led to their designation as pan-assay interference compounds (PAINS). NPs lack comparable scrutiny, which this study aims to rectify. Systematic mining of 80+ years of the phytochemistry and biology literature, using the NAPRALERT database, revealed that only 39 compounds represent the NPs most reported by occurrence, activity, and distinct activity. Over 50% are not explained by phenomena known for synthetic libraries, and all had manifold ascribed bioactivities, designating them as invalid metabolic panaceas (IMPs). Cumulative distributions of ∼200,000 NPs uncovered that NP research follows power-law characteristics typical for behavioral phenomena. Projection into occurrence–bioactivity–effort space produces the hyperbolic black hole of NPs, where IMPs populate the high-effort base. PMID:26505758

The plants are traditionally used as laxative, anthelmintic and for alexipharmic effects. The plants are also equally use in eye, blood diseases, bronchitis, abdominal pain, stangury, thirst, itch, lecoderma, fever, wounds, burns, piles and urinary calculi. The flowers of various plants are prescribed as stimulants, cardiotonic, in body swelling while leaves are used as purgative and in cutaneous eruptions. The roots are used for coloring food stuffs, oils and dying wool and in medicinal preparations. This review emphasizes the distribution, morphology, phytochemical constituents, ethnopharmacology, which may help in future research. PMID:24347922

Species of the genus Codonopsis are perennial herbs mainly distributed throughout East, Southeast and Central Asia. As recorded, they have been used as traditional Chinese medicines since the Qing Dynasty, where they were claimed for strengthening the spleen and tonifying the lung, as well as nourishing blood and engendering liquid. Some species are also used as food materials in southern China and Southeast Asia, such as tea, wine, soup, plaster, and porridge. The review aims to assess the ethnopharmacological uses, explicit the material basis and pharmacological action, promote the safety of medical use, and suggest the future research potentials of Codonopsis. Information on the studies of Codonopsis was collected from scientific journals, books, and reports via library and electronic data search (PubMed, Elsevier, Scopus, Google Scholar, Springer, Science Direct, Wiley, Researchgate, ACS, EMBASE, Web of Science and CNKI). Meanwhile, it was also obtained from published works of material medica, folk records, ethnopharmacological literatures, Ph.D. and Masters Dissertation. Plant taxonomy was confirmed to the database "The Plant List" (www.theplantlist.org). Codonopsis has been used for medicinal purposes all around the world. Some species are also used as food materials in southern China and Southeast Asia. The chemical constituents of Codonopsis mainly are polyacetylenes, polyenes, flavonoids, lignans, alkaloids, coumarins, terpenoids, steroids, organic acids, saccharides, and so on. Extract of Codonopsis exhibit extensive pharmacological activities, including immune function regulation, hematopoiesis improvement, cardiovascular protection, neuroprotection, gastrointestinal function regulation, endocrine function regulation, cytotoxic and antibacterial effects, anti-aging and anti-oxidation, etc. Almost no obvious toxicity or side effect are observed and recorded for Codonopsis. The traditional uses, phytochemistry, pharmacology and toxicology of Codonopsis are reviewed in this paper. Species of the genus have long been used as traditional medicines and food materials, they are reported with a large number of chemical constituents with different structures, extensive pharmacological activities in immune system, blood system, digestive system, etc. and almost no toxicity. More profound studies on less popular species, pharmacodynamic material basis and pharmacological mechanism, and quality assurance are suggested to be carried out to fulfil the research on the long-term clinical use and new drug research of Codonopsis.

Granica, Sebastian; Piwowarski, Jakub P; Czerwińska, Monika E; Kiss, Anna K

2014-10-28

The Epilobium genus (willowherb) comprises of ca. 200 species of herbaceous plants distributed around the world. Infusions prepared form willowherbs have been traditionally used externally in skin and mucosa infections and in the treatment of benign prostate hyperplasia. Nowadays extracts from different Epilobium species are widely used by patients, however the lack of clinical studies does not allow to fully establish their efficacy. The present review summarizes published data on phytochemistry, ethnopharmacological use and pharmacological studies concerning willowherb species investigated throughout past few decades. Literature survey was performed using Scopus, PubMed, Web of Science and Reaxys databases looking for papers and patents focused on chemical composition and bioactivity of Epilobium species. Systematic research in ethnopharmacological literature in digitalized sources of academic libraries was also carried out. The chemical composition of different Epilobium species and their bioactivities are described. The detailed information on constituents isolated and detected by chromatographic methods is given. The studies show that polyphenols are main compounds occurring in Epilobium herb among which flavonoids, phenolic acids and tannins (oenothein B and oenothein A) are dominating constituents. The extracts and some isolated compounds from Epilobium sp. were shown to possess antimicrobial, anti-proliferative, anti-inflammatory, analgesic and antioxidative activities. Because many studies suggest that oenothein B as dominating constituent may be responsible for Epilobium sp. pharmacological effects, its documented bioactivities were also described. The pharmacological studies performed on Epilobium justify the traditional use of this species in external and in gastrointestinal inflammations. As far as the treatment of benign prostate hyperplasia (BPH) is considered, in the literature, there are some reports indicating that Epilobium extracts have a beneficial effect for this disorder, but the number of in vitro studies is not sufficient and the in vivo studies are not conclusive or too preliminary to draw a final conclusion about the efficacy of Epilobium preparations. More in vitro, in vivo and clinical studies to confirm this mode of action are strongly needed. Epilobium's extracts have also documented antioxidative and potential anti-inflammatory properties. Oenothein B can be considered as responsible for some of Epilobium pharmacological properties. Because of the lack of clinical data further studies are needed to provide an evidence base for traditional uses of plant materials belonging to the Epilobium genus.

Patel, Jagruti J; Acharya, Sanjeev R; Acharya, Niyati S

2014-06-11

Clerodendrum serratum (L.) Moon. (Verbenaceae) is an important medicinal plant growing in the tropical and warm temperate regions like Africa, Southern Asia; Malaysia and distributed throughout in forests of India and Sri Lanka. It is traditionally valued and reported for treating pain, inflammation, rheumatism, respiratory disorders, fever and malarial fever in India with a long history. To provide a comprehensive overview of the traditional and ethno medicinal uses, phytochemistry and biological activities of C. serratum with clinical and toxicity data and possibly make recommendations for further research. All relevant worldwide accepted databases were searched for the terms "Clerodendrum", "Clerodendrum serratum", "Bharangi" and "Cheruthekku" along with the other literature from Indian classical texts and pharmacopoeias. There was no specific timeline set for the search. The accessible literatures available on C. serratum were collected via electronic search using Pubmed, Scopus, Science Direct and traditional books reports on ethnopharmacology and traditional medicines. C. serratum has played an important role in Indian system of medicine. In addition to the common local use in respiratory diseases, other ethnomedicinal uses include treatment of pain, inflammation, rheumatism and fever especially malarial fever. Scientific studies on extracts and formulations revealed anti-asthmatic, mast cell stabilization and anti-allergic effects of roots of C. serratum. Reported data on pharmacological activities also includes hepatoprotective, anti-oxidant, anti-inflammatory and anticancer potential of the drug. Saponins (terpenoids and steroids), flavonoids and phenolics isolated from roots have been the focus of phytochemical investigations as the biological activity has been ascribed to the saponins, which are known to possess anti-inflammatory and anti-cancer activity. Isolated bioactives from roots like icosahydropicenic acid and ursolic acid have been claimed to offer anti-allergic and hepatoprotective activity. Therapeutic potential of roots and leaves of C. serratum has been demonstrated in the conditions like asthma, allergy, fever, inflammation and liver disorders attributed to the presence of various flavonoids, phenolics and saponins present in the drug. Many ethnobotanical claims have been confirmed through modern in-vitro and in-vivo pharmacological studies of different extracts and isolates from plant; however, additional studies on the biomarkers are needed to establish mechanism of action and to validate the traditional use of this drug in clinical practices after proper safety assessment.

2015-08-22

Sophora flavescens (Fabaceae), also known as Kushen (Chinese: ), has been an important species in Chinese medicine since the Qin and Han dynasties. The root of Sophora flavescens has a long history in the traditional medicine of many countries, including China, Japan, Korea, India and some countries in Europe. In traditional Chinese medicine (TCM), Sophora flavescens has been used extensively, mainly in combination with other medicinal plants in prescriptions to treat fever, dysentery, hematochezia, jaundice, oliguria, vulvar swelling, asthma, eczema, inflammatory disorders, ulcers and diseases associated with skin burns. The aim of this review is to provide updated and comprehensive information regarding the botany, ethnopharmacology, phytochemistry, biological activities and toxicology of Sophora flavescens and to discuss possible trends and opportunities for further research on Sophora flavescens. We systematically searched major scientific databases (PubMed, Elsevier, SpringerLink, Google Scholar, Medline Plus, ACS, "Da Yi Yi Xue Sou Suo (http://www.dayi100.com/login.jsp)", China Knowledge Resource Integrated (CNKI) and Web of Science) for information published between 1958 and 2015 on Sophora flavescens. Information was also acquired from local classic herbal literature, conference papers, government reports, and PhD and MSc dissertations. The broad spectrum of biological activities associated with Sophora flavescens has been considered a valuable resource in both traditional and modern medicine. Extracts are taken either orally or by injection. More than 200 compounds have been isolated from Sophora flavescens, and the major components have been identified as flavonoids and alkaloids. Recent in vitro and in vivo studies indicate that at least 50 pure compounds and crude extracts from Sophora flavescens possess wide-ranging antitumor, antimicrobial, antipyretic, antinociceptive, and anti-inflammatory pharmacological abilities. The anticancer and anti-infection abilities of these components are especially attractive areas for research. Sophora flavescens is a promising traditional medicine, but there is a need for more precise studies to test the safety and clinical value of its main active crude extracts and pure compounds and to clarify their mechanisms of action. Moreover, some existing studies have lacked systematic methods and integration with the existing literature, and some of the experiments were isolated, used small sample sizes and were unreliable. More validated data are therefore required. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Areca catechu L. (Arecaceae), widely distributed in South and Southeast Asia, is a popular traditional herbal medicine that can be chewed for the purpose of dispersing accumulated fluid in the abdominal cavity and killing worms. The present paper aims to provide an up-to-date review on the traditional uses and advances in the botany, phytochemistry, pharmacology and toxicology of this plant. Furthermore, the possible trends and a perspective for future research of this plant are also discussed. A literature search was performed on A. catechu based on classic books of herbal medicine, PhD. and MSc. dissertations, government reports, the state and local drug standards, scientific databases including Pubmed, SciFinder, Scopus, the Web of Science, Google Scholar, and others. Various types of information regarding this plant are discussed in corresponding parts of this paper. In addition, perspectives for possible future studies of A. catechu are discussed. The seeds of A. catechu (areca nut) have been widely used in clinical practice in China, India and other South and Southeast Asian Countries. Currently, over 59 compounds have been isolated and identified from A. catechu, including alkaloids, tannins, flavones, triterpenes, steroids, and fatty acids. The extracts and compounds isolated from A. catechu have many pharmacological activities. These include antiparasitic effects, anti-depressive effects, anti-fatigue effects, antioxidant effects, antibacterial and antifungal effects, antihypertensive effects, anti-inflammatory and analgesic effects, anti-allergic effects, the promotion of digestive functions, suppression of platelet aggregation, regulatory effects on blood glucose and lipids, etc. Although arecoline is the primary active constituent of A. catechu, it is also the primary toxic compound. The main toxicities of arecoline are the promotion of oral submucosal fibrosis (OSF) and cytotoxic effects on normal human cells, which involve inducing apoptosis. As an important herbal medicine, A. catechu has potential for the treatment of many diseases, especially parasitic diseases, digestive function disorders, and depression. Many traditional uses of A. catechu have now been validated by current investigations. However, further research should be undertaken to investigate the clinical effects, toxic constituents, target organs, and pharmacokinetics and to establish criteria for quality control for A. catechu-derived medications. In addition, it will be interesting to investigate the active macromolecular compounds and active constituents other than alkaloids in both raw and processed products of A. catechu.

Clinacanthus nutans (Burm. f.) Lindau, a widely used medicinal plant, is extensively grown in tropical Asia and Southeast Asian countries. C. nutans, with its broad spectrum of pharmacological activities, has been traditionally used to treat cancer, inflammatory disorders, diabetes, insect bites, and skin problems, consumed as a vegetable, mixed with fresh juices, in concoctions, and as a whole plant. The present review analyzes the advances in the ethnopharmacology, phytochemistry, pharmacology, and toxicology of C. nutans. In addition, the needs and perspectives for future investigation of this plant are addressed. This review aims to provide a comprehensive report on the ethnomedicinal use, phytochemistry, pharmacological activities, molecular mechanisms, and nutritional values of C. nutans. The present review will open new avenues for further in-depth pharmacological studies of C. nutans for it to be developed as a potential nutraceutical and to improve the available products in the market. All the available information on C. nutans was collected using the key words "Clinacanthus nutans" and/or "ethnomedicine" and/or "phytochemicals" and/or "anticancer" and/or "anti-inflammatory" and/or "antiviral" through an electronic search of the following databases: PubMed, Web of Science, EMBASE, Cochrane Library, Clinical Trials.org, SciFinder Scholar, Scopus, and Google Scholar. In addition, unpublished materials, Ph.D. and M.Sc. dissertations, conference papers, and ethnobotanical textbooks were used. The Plant List (www.theplantlist.org) and International Plant Name Index databases were used to validate the scientific name of the plant. The literature supported the ethnomedicinal uses of C. nutans as recorded in Thailand, Indonesia, and Malaysia for various purposes. Bioactivities experimentally proven for C. nutans include cytotoxic, anticancer, antiviral, anti-inflammatory, immunomodulatory, antidiabetic, antioxidant, antihyperlipidemic, antimicrobial, and chemotherapeutic (in aquaculture) activities. Most of these activities have so far only been investigated in chemical, cell-based, and animal assays. Various groups of phytochemicals including five sulfur-containing glycosides, eight chlorophyll derivatives, nine cerebrosides, and a monoacylmonogalactosyl glycerol are present in C. nutans. The presence of two glycerolipids, four sulfur-containing compounds, six known flavones, a flavanol, four flavonols, two phytosterols, one polypeptide, and various phenolics and fatty acids largely influences its diverse bioactivities. Numerous reports justify the ethnomedicinal use of C. nutans as an antiviral agent in treating herpes simplex virus and varicella-zoster virus infections and as part of a traditional anticancer anti-inflammatory concoction agent for various inflammatory diseases. C. nutans tea was reported to have a good percentage of carbohydrate, crude protein, minerals, essential amino acids, nonessential amino acids, and essential fatty acids. Acute, subacute, and subchronic toxicity studies demonstrated that oral administration of ethanol and methanol extracts of C. nutans to male Swiss albino mice and male Sprague-Dawley (SD) rats, respectively, did not lead to any toxicity or adverse effects on the animal behavior and organs when used in amounts as high as 2g/kg. The collected literatures demonstrated that, as an important traditional medicine, C. nutans is a promising ethnomedicinal plant with various extracts and bioactive compounds exhibiting multifarious bioactivities. However, it is important for future studies to conduct further in vitro and in vivo bioactivity evaluations systematically, following the standard pharmacology guidelines. It is crucial to elucidate in-depth molecular mechanisms, structure-activity relationships, and potential synergistic and antagonistic effects of multi-component extracts and bioactive constituents derived from C. nutans. Further studies should also focus on comprehensive toxicity that includes long-term effects and adverse effects on target organs of C. nutans and bioactive compounds in correlation with the specific pharmacological effects.

A modification of the Bjork flap in tracheostomies for head and neck cancer patients.

PubMed

Stathopoulos, P; Stassen, L

2018-05-07

The etymology of the word tracheotomy derives from two Ancient Greek words: the word trachea (Greek τραχɛία tracheía) and the word stoma (Greek στóμα stóma) meaning "mouth," and refers to the making of an opening. It is believed that an early tracheostomy was performed by the Greek physician Asclepiades of Bithynia, in order to treat upper airway obstruction. A secure airway in the intraoperative and early postoperative period is of paramount importance for a number patients undergoing head and neck cancer surgery. We describe a modification of the Bjork flap used in tracheostomies for head and neck cancer patients, which allows tracheal outline reconstitution and significantly decreases the risk of respiratory obstruction and clinically evident tracheal stenosis, as our results have shown, at least five years after the last patient was discharged.

Scartezzini, P; Speroni, E

2000-07-01

A lot of medicinal plants, traditionally used for thousands of years, are present in a group of herbal preparations of the Indian traditional health care system (Ayurveda) named Rasayana proposed for their interesting antioxidant activities. Among the medicinal plants used in ayurvedic Rasayana for their therapeutic action, some of these have been throughly investigated. In the present paper seven plants (Emblica officinalis L., Curcuma longa L., Mangifera indica L., Momordica charantia L., Santalum album L., Swertia chirata Buch-Ham, Withania somnifera (L.) Dunal) are viewed for their historical, etymological, morphological, phytochemical and pharmacological aspects. The plants described contain antioxidant principles, that can explain and justify their use in traditional medicine in the past as well as the present. In order to identify the plants with antioxidant activity in Ayurveda, a formulation of some rasayanas with well defined antioxidant properties has been examinated. For this purpose, we have considered Sharma's work on the preparation MAK4, MAK5, MA631, MA 471, MA Raja's Cup, MA Student Rasayana, MA Ladies Rasayana.

On the tracks of sandarac, review and chemical analysis.

PubMed

Azémard, Clara; Ménager, Matthieu; Vieillescazes, Cathy

2017-12-01

The sandarac resin (Tetraclinis articulata) has been long used for its properties, mostly as a varnish component. Called juniper resin until the nineteenth century, the real botanical origin of sandarac is still unclear. The first approach to this issue is the review of the evolution of the etymology, terminology, and botanical description of sandarac through time. It seems that sandarac was mainly coming from T. articulata but the use of some juniper resins before the twentieth century is not to be excluded. The second approach is a chemical one; we used gas chromatography coupled to mass spectrometry to characterise the resin. As sandarac was the main component of the famous Italian varnish Vernice liquida, its characterisation is important for old paintings studies. However, although we could hope to differentiate sandarac, Juniperus communis and Juniperus oxycedrus resins by looking at their chemical composition, it appears that these resins are very similar. Besides, we notice a lack of old varnishes containing sandarac which complicates our work.

The history of Latin teeth names.

Šimon, František

2015-01-01

This paper aims to give an account of the Latin naming of the different types of teeth by reviewing relevant historical and contemporary literature. The paper presents etymologies of Latin or Greek teeth names, their development, variants and synonyms, and sometimes the names of their authors. The Greek names did not have the status of official terms, but the Latin terms for particular types of teeth gradually established themselves. Names for the incisors, canines and molars are Latin calques for the Greek ones (tomeis, kynodontes, mylai), dens serotinus is an indirect calque of the Greek name (odús) opsigonos, and the term pre-molar is created in the way which is now common in modern anatomical terminology, using the prefix prae- = pre and the adjective molaris. The Latin terms dentes canini and dentes molares occur in the Classical Latin literature, the term (dentes) incisivi is found first time in medieval literature, and the terms dentes premolares and dens serotinus are modern-age ones.

On (scientific) integrity: conceptual clarification.

PubMed

Patrão Neves, Maria do Céu

2018-06-01

The notion of "integrity" is currently quite common and broadly recognized as complex, mostly due to its recurring and diverse application in various distinct domains such as the physical, psychic or moral, the personal or professional, that of the human being or of the totality of beings. Nevertheless, its adjectivation imprints a specific meaning, as happens in the case of "scientific integrity". This concept has been defined mostly by via negativa, by pointing out what goes against integrity, that is, through the identification of its infringements, which has also not facilitated the elaboration of an overarching and consensual code of scientific integrity. In this context, it is deemed necessary to clarify the notion of "integrity", first etymologically, recovering the original meaning of the term, and then in a specifically conceptual way, through the identification of the various meanings with which the term can be legitimately used, particularly in the domain of scientific research and innovation. These two steps are fundamental and indispensable for a forthcoming attempt at systematizing the requirements of "scientific integrity".

Who was Rumpelstiltskin?

PubMed

Rand, H

2000-10-01

The author describes the way in which Rumpelstiltskin has perplexed and enthralled readers since the brothers Grimm recovered the tale from the realm of folklore. In standard translation, the story now lives in a fixed literary form and, consequently, in the imagination of every child who has ever heard or read the story--virtually every person in the English-speaking world. Therefore, deeply rooted in childhood experiences, Rumpelstiltskin can be expected to appear in analysis, and he does. The compelling central character is the title figure, Rumpelstiltskin, whose name and actions tell us who he is and what he was intended to 'mean'--especially to his contemplated audience. The original narrators of and listeners to this tale were female visitors to the evening spinning chamber (Spinnstube), where women gathered and told tales to amuse themselves to ward off sleep while they spun. The butt of this story is male impotence and bluster, and the key to the story's meaning arises from matching the etymological roots of the central character's name with his actions as they appear philologically and psychoanalytically.

R A Cowley, the "Golden Hour," the "Momentary Pause," and the "Third Space".

PubMed

Clark, David E

2017-12-01

R Adams Cowley (1917-1991), the Baltimore thoracic and trauma surgeon, was an outstanding politician and promoter of emergency medical services. His skills included the effective use of language, for example, identifying the critical time immediately after injury as a "golden hour," and describing shock as a "momentary pause in the act of death." Conversely, Cowley avoided the tendency of some contemporaries to justify massive crystalloid infusion by invoking a "third space." Cowley is often assumed to have originated the first two phrases, but, in fact, their histories go back at least to the 19th century and illustrate the development of surgical science. The "third space" is often assumed to have originated with Cowley's contemporary, Tom Shires (1925-2007), but, in fact, neither of them used the phrase to describe Shires' controversial theories about an extracellular fluid deficit after trauma. Reviewing the actual etymology of these terms may help clarify the history of the underlying scientific ideas and enable more effective communication in the future.

During its evolution the cesarean section has meant different things to different people. The indications for it have changed throughout the course of history. From the initial purpose to retrieve an infant from a dead or dying mother in order to bury the child separately from his mother, to contemporary indications. This article strives to follow the roots of this common procedure--starting from the descriptions in the ancient Greek mythology, through the imperial Roman law, aspects of Judaism and the evolution of the procedure throughout modern history. Major improvements in the surgical techniques, the introduction of anesthesia and aseptic procedures contributed to the decline in mortality and morbidity rates. We will attempt to find the etymology for the expression "cesarean section" which has commonly been accounted to Julius Caesar's name, although history denies it. This review takes us on a historical journey, from ancient times to nowadays, in which we follow the course and nature of a procedure being performed daily in thousands of hospitals.

Tuskegee University Experience Challenges Conventional Wisdom: Is Integrative Bioethics Practice the New Ethics for the Public's Health?

2013-01-01

The Tuskegee University National Center for Bioethics in Research and Health Care was established in 1999 in partial response to the Presidential Apology for the United States Public Health Service's Study of Untreated Syphilis in the Negro Male conducted in Macon County, Alabama, from 1932 to 1972. The Center's mission of promoting equity and justice in health and health care for African Americans and other underserved populations employs an integrative bioethics approach informed by moral vision. Etymological and historical analyses are used to delineate the meaning and evolution of bioethics and to provide a basis for Tuskegee's integrative bioethics niche. Unlike mainstream bioethics, integrative bioethics practice is holistic in orientation, and more robust for understanding the epistemic realities of minority life, health disparities, and population health. The conclusion is that integrative bioethics is relevant to the survival of all people, not just a privileged few; it could be the new ethics for the public's health. PMID:23124497

An exploratory study of selected female registered nurses: meaning and expression of nurturance.

PubMed

Geissler, E M

1990-05-01

The words 'nurse' and 'nursing' originate in the word 'nurture' which dates back to the 14th century. 'Nurturance' appeared for the first time in the 1976 Supplement to the Oxford English Dictionary and in a United States dictionary in 1983. Etymologically and semantically bound to nursing, little is known about the term nurturance. An exploratory design using phenomenological analysis was applied to understand the female registered nurses' experience of nurturing patients throughout the life-span and to uncover behaviours commonly believed nurturant. Interviews with 14 RNs practising in diverse settings revealed 39 nurturant behaviours that were intuited into four themes describing the subjects' perceived structure of nurturance as: (1) enabling maximum potential; (2) providing physical and emotional protection; (3) engaging in a supportive interaction; and (4) conveying shared humanity. Data were formulated into an exhaustive description of the phenomenon nurturance. Additionally, the results support Greenberg-Edelstein's theoretical model of the positive reciprocity of nurturance between nurse and patient.

Cardio-renal syndromes: from foggy bottoms to sunny hills.

PubMed

Ronco, Claudio

2011-11-01

"Cardio-renal syndromes" (CRS) are disorders of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other. The current definition has been expanded into five subtypes whose etymology reflects the primary and secondary pathology, the time-frame and simultaneous cardiac and renal co-dysfunction secondary to systemic disease: CRS type I: acute worsening of heart function (AHF-ACS) leading to kidney injury and/or dysfunction. CRS type II: chronic abnormalities in heart function (CHF-CHD) leading to kidney injury or dysfunction. CRS type III: acute worsening of kidney function (AKI) leading to heart injury and/or dysfunction. CRS type IV: chronic kidney disease (CKD) leading to heart injury, disease and/or dysfunction. CRS type V: systemic conditions leading to simultaneous injury and/or dysfunction of heart and kidney. These different subtypes may have a different pathophysiological mechanism and they may represent separate entities in terms of prevention and therapy.

Loops and Self-Reference in the Construction of Dictionaries

NASA Astrophysics Data System (ADS)

Levary, David; Eckmann, Jean-Pierre; Moses, Elisha; Tlusty, Tsvi

2012-07-01

Dictionaries link a given word to a set of alternative words (the definition) which in turn point to further descendants. Iterating through definitions in this way, one typically finds that definitions loop back upon themselves. We demonstrate that such definitional loops are created in order to introduce new concepts into a language. In contrast to the expectations for a random lexical network, in graphs of the dictionary, meaningful loops are quite short, although they are often linked to form larger, strongly connected components. These components are found to represent distinct semantic ideas. This observation can be quantified by a singular value decomposition, which uncovers a set of conceptual relationships arising in the global structure of the dictionary. Finally, we use etymological data to show that elements of loops tend to be added to the English lexicon simultaneously and incorporate our results into a simple model for language evolution that falls within the “rich-get-richer” class of network growth.

The novel assessment tool Cross-Linguistic Lexical Tasks (LITMUS-CLT) aims for comparable cross-linguistic assessment of multilingual children's lexical skills by basing each language version on two language-specific variables: age of acquisition (AoA) and complexity index (CI), a novel measure related to phonology, morphology, exposure and etymology. This article investigates the validity of this methodology, asking whether the underlying properties are robust predictors of children's performance. The Polish and Norwegian CLTs were used to assess 32 bilingual Polish-Norwegian, 34 monolingual Norwegian and 36 monolingual Polish children. The effects of AoA and CI were contrasted with frequency in child directed speech (CDS) and imageability, two known predictors of lexical development. AoA was a reliable predictor of performance within all parts of CLT, in contrast to CI. Apart from AoA, only exposure and CDS frequency had a significant effect within both monolinguals and bilinguals. These results indicate that CLT assesses lexical skills in a cross-linguistically comparable manner, but suggest a revision of the CI measure.

In order to study the special composition of animals used in the medieval medicine of Azerbaijan, a wide range of medieval sources on medicine and pharmacognosy from the collection of the Institute of Manuscripts of the Azerbaijan Academy of Sciences in Baku has been studied. About 40 medieval sources from the 10-18th centuries including 17 manuscripts in Turkic, Persian and Arabic have been selected as the objects of this study. As a result, 150 species of animals described in medieval Azerbaijani books on medicine and pharmacy have been identified. Many of the identified animals are mammals, (47 species or 31% of total number of identified species). The medieval authors describe 12 species of reptiles and 4 species of Amphibians (frogs, toads, salamanders and tree-frogs (Hyla arborea). 15 species of fishes described in medieval manuscripts have been identified. The identified molluscs are cuttlefish (Sepia officinalis), mussel (Mytilus edulis), octopus (Octopus vulgaris) and snail (Helix pomatia). Most crustaceans used in medieval Azerbaijan medicine belong to Decopoda. Medieval manuscripts contain numerous names of various worms and insects (ants, flies, beetles, etc.), however their exact identification is rather difficult. As usual, medieval authors unite a number of species under one name and do not give sufficient information about their morphology. Results of the research create grounds for the idea that the recommendations of the medieval authors on the medicinal application of animals can be applied to modern medicine once they have been experimentally and clinically tested.

The Third Month Fair in Dali is a historical festival and fair. The market of traditional medicine (TM) is one of the main parts in the fair, which has important influence on local and peripheral people. In this study, approaches of ethnobotany, pharmacognosy, and participatory rural appraisal were used in market survey. Twenty-six druggists were selected randomly as informants and their TMs were recorded. As a result, 427 TMs were recorded including 362 plant medicines, 33 animal medicines, 13 mineral medicines and 19 unidentified medicines. Xinyi, Shanza and Gancao were the most popular medicines due to their popular usages, whereas Sanqi, Tianma and Renshen were relatively fewer in this investigation probably owing to high price and limited output. The plant medicines were from medicinal plants of 117 families belonged to Angiosperm, Gymnospermae, Pteridophyta, Bryophyta, Lichenes and Fungi. Asteraceae, Apiaceae and Fabaceae provided the maximum numbers of TMs successively. Moreover, these TMs were mainly from the cultivated especially familiar TMs, which reflected significant progress in utilization and conservation of medicinal resource in China. Medicinal market in the Third Month Fair is the most important traditional bazaar in Yunnan province. This study systematically surveyed TMs in the fair for the first time, analyzing and revealing resource compositions and current market situations. These newly gathered data provided precious information for development of medicine cultivation, resource protection and market management as well as further pharmacognostical, pharmacological and clinical researches.

Achillea L. (Compositae or Asteraceae) is a widely distributed medicinal plant throughout the world and has been used since ancient time. Popular indications of the several species of this genus include treatment of wounds, bleedings, headache, inflammation, pains, spasmodic diseases, flatulence and dyspepsia. Phytochemical investigations of Achillea species have revealed that many components from this genus are highly bioactive. There are many reports on the mentioned folk and traditional effects. Although, the medicinal properties of Achillea plants are recognized worldwide, there are only one review article mainly about the structures of the phytochemical constituents of Achillea. The present paper reviews the medicinal properties of various species of Achillea, which have been examined on the basis of the scientific in vitro, in vivo or clinical evaluations. Various effects of these plants may be due to the presence of a broad range of secondary active metabolites such as flavonoids, phenolic acids, coumarins, terpenoids (monoterpenes, sesquiterpenes, diterpenes, triterpenes) and sterols which have been frequently reported from Achillea species.

Wang, Chong-Zhi; Anderson, Samantha; Yuan, Chun-Su

2016-01-01

Asian ginseng, American ginseng, and notoginseng are three major species in the ginseng family. Notoginseng is a Chinese herbal medicine with a long history of use in many Oriental countries. This botanical has a distinct ginsenoside profile compared to other ginseng herbs. As a saponin-rich plant, notoginseng could be a good candidate for cancer chemoprevention. However, to date, only relatively limited anticancer studies have been conducted on notoginseng. In this paper, after reviewing its anticancer data, phytochemical isolation and analysis of notoginseng is presented in comparison with Asian ginseng and American ginseng. Over 80 dammarane saponins have been isolated and elucidated from different plant parts of notoginseng, most of them belonging to protopanaxadiol or protopanaxatriol groups. The role of the enteric microbiome in mediating notoginseng metabolism, bioavailability, and pharmacological actions are discussed. Emphasis has been placed on the identification and isolation of enteric microbiome-generated notoginseng metabolites. Future investigations should provide key insights into notoginseng's bioactive metabolites as clinically valuable anticancer compounds.

Emerging clinical usage and pharmacological effects have been achieved in using Rehmanniae Radix either singly or in combination with other herbs to treat skeletal diseases in traditional Chinese medicine (TCM) in the recent years. This study is aimed to provide a comprehensive review about the historical TCM interpretation of the action of Rehmanniae Radix in osteoporosis, its usage in clinical trials and osteoporotic models, its main phytochemical constituents, and its pharmacokinetics. Several databases included PubMed, China Knowledge Resource Integrated Database, China Science and Technology Journal Database, National Science and Technology Library and the Web of Science Database were consulted to locate the publications pertaining to Rehmanniae Radix. The initial inquiry was conducted for the presence of the following terms combinations in the abstracts: Rehmanniae Radix, Dihuang, phytochemistry, pharmacokinetics, osteoporosis, bone, osteoclast and osteoblast. About 330 research papers and reviews were consulted. In TCM, Rehmanniae Radix exerts the anti-osteoporotic effect via regulating the functions of kidney and liver as well as improving blood circulation. 107 clinical trials are identified that used Rehmanniae Radix in combination with other herbs to treat post-menopausal, senile and secondary osteoporosis. Most of the clinical trials are characterized by high efficacy and no obvious adverse effects. However, the efficacies of these clinical trials are limited because of small patient sample size, short treatment duration and poor clinical design. In addition, TCM herbs under the clinical study are not clear because of a lack of standardization and authentication. The pharmacokinetics data demonstrate that the ingredients of Rehmanniae Radix are widely distributed after administration, and that catalpol and ajugol as well as acetoside are supposed to be the active constituents. More than 140 individual compounds have been currently isolated from this plant and reported to show pleiotropic effects on various diseases. Rehmanniae Radix displays bone protecting features in the osteoporosis models via the delicate balance between osteoclastogenesis and osteoblastogenesis through single herb extracts and its isolated compounds. The successful inclusion of Rehmanniae Radix in clinical trials and preclinical studies for the management of osteoporosis has attracted rising attentions for identifying potential anti-osteoporotic candidates from this plant and clinical existing TCM formulas, which will further speed up anti-osteoporosis drug discovery processes. Properly designed and well controlled prospective studies are still needed to further demonstrate bone protective actions and safe use of this herb and its ingredients.

The medicinal plant Morinda officinalisHow. (MO) and its root have long been used in traditional medicines in China and northeast Asia as tonics for nourishing the kidney, strengthening the bone and enhancing immunofunction in the treatment of impotence, osteoporosis, depression and inflammatory diseases such as rheumatoid arthritis and dermatitis. This review aims to sum up updated and comprehensive information about traditional usage, phytochemistry, pharmacology and toxicology of MO and provide insights into potential opportunities for future research and development of this plant. A bibliographic investigation was performed by analyzing the information available on MO in the internationally accepted scientific databases including Pubmed, Scopus and Web of Science, SciFinder, Google Scholar, Yahoo, Ph.D. and M.Sc. dissertations in Chinese. Information was also obtained from some local and foreign books on ethnobotany and ethnomedicines. The literature supported the ethnomedicinal uses of MO as recorded in China for various purposes. The ethnomedical uses of MO have been recorded in many regions of China. More than 100 chemical compounds have been isolated from this plant, and the major constituents have been found to be polysaccharides, oligosaccharides, anthraquinones and iridoid glycosides. Crude extracts and pure compounds of this plant are used as effective agents in the treatment of depression, osteoporosis, fatigue, rheumatoid arthritis, and infertility due to their anti-depressant, anti-osteoporosis, pro-fertility, anti-radiation, anti-Alzheimer disease, anti-rheumatoid, anti-fatigue, anti-aging, cardiovascularprotective, anti-oxidation, immune-regulatory, and anti-inflammatory activities. Pharmacokinetic studies have demonstrated that the main components of MO including monotropein and deacetyl asperulosidic acid are distributed in various organs and tissues. The investigation on acute toxicity and genotoxicity indicated that MO is nontoxic. There have no reports on significant adverse effect at a normal dose in clinical application, but MO at dose of more than 1000mg/kg may cause irritability, insomnia and unpleasant sensations in individual cases. MO has emerged as a good source of traditional medicines. Some uses of this plant in traditional medicines have been validated by pharmacological investigations. However, the molecular mechanism, structure-activity relationship, and potential synergistic and antagonistic effects of its multi-components such as polysaccharides, oligosaccharides, anthraquinones and iridoid glycosides need to be further elucidated, and the structural feature of polysaccharides also need to be further clarified. Sophisticated analytical technologies should be developed to comprehensively evaluate the quality of MO based on HPLC-fingerprint and content determination of the active constituents, knowing that these investigations will help further utilize this plant.

Polygonum multiflorum Thunb., which is known as Heshouwu ( in Chinese) in China. It is traditionally valued and reported for hair-blacking, liver and kidney-tonifying and anti-aging effects as well as low toxicity. The aim of this review is to provide comprehensive information on the botany, traditional uses, phytochemistry, pharmacological research and toxicology of Polygonum multiflorum, based on the scientific literature. Moreover, trends and perspectives for future investigation of this plant are discussed. It will build up a new foundation for further study on Polygonum multiflorum. A systematic review of the literature on Polygonum multiflorum was performed using several resources, including classic books on Chinese herbal medicine and various scientific databases, such as PubMed, SciFinder, the Web of Science, Science Direct, China Knowledge Resource Integrated (CNKI). Polygonum multiflorum is widely distributed throughout the world and has been used as a traditional medicine for centuries in China. The ethnomedical uses of Polygonum multiflorum have been recorded in many provinces of China and Japan for nine species of adulterants in six families. More than 100 chemical compounds have been isolated from this plant, and the major components have been determined to be stilbenes, quinones, flavonoids and others. Crude extracts and pure compounds of this plant are used as effective agents in pre-clinical and clinical practice due to their anti-aging, anti-hyperlipidaemia, anti-cancer and anti-inflammatory effects and to promote immunomodulation, neuroprotection, and the curing of other diseases. However, these extracts can also lead to hepatotoxicity, nephrotoxicity and embryonic toxicity. Pharmacokinetic studies have demonstrated that the main components of Polygonum multiflorum, such as 2,3,5,4'-tetrahydroxystilbene-2-O-β-d-glucopyranoside and emodin are distributed among many organs and tissues. Therapeutic potential of Polygonum multiflorum has been demonstrated in the conditions like Alzheimer׳s disease, Parkinson׳s disease, hyperlipidaemia, inflammation and cancer, which is attributed to the presence of various stilbenes, quinones, flavonoids, phospholipids and other compounds in the drug. On the other hand, the adverse effects (hepatotoxicity, nephrotoxicity, and embryonic toxicity) of this plant were caused by the quinones, such as emodin and rhein. Thus more pharmacological and toxicological mechanisms on main active compounds are necessary to be explored, especially the combined anthraquinones (Emodin-8-O-β-d-glucopyranoside, Physcion-8-O-β-d-glucopyranoside, etc.) and the variety of stilbenes.

Citri Reticulatae Pericarpium (Rutaceae, CRP), commonly called as Chenpi () in Chinese, is most frequently used as a qi-regulating drug in thousands of Chinese medicine prescriptions. CRP is found mainly in major citrus-producing areas such as the Guangdong, Guangxi, Sichuan, Fujian, and Zhejiang Provinces of China. Since thousands of years in China, CRP has been used widely in clinical practice to treat nausea, vomiting, indigestion, anepithymia, diarrhea, cough, expectoration, and so on. Currently, CRP is listed in the Pharmacopoeia of the People's Republic of China. The present paper reviews the botany, ethnopharmacology, phytochemistry, pharmacology, quality control, and toxicology of CRP. Information on CRP was gathered from various sources including the books on traditional Chinese herbal medicine; scientific databases including Elsevier, PubMed, and ScienceDirect; Baidu Scholar; CNKI; and others and from different professional websites. Approximately 140 chemical compounds have been isolated and identified from CRP. Among them, volatile oils and flavonoids are generally considered as the main bioactive and characteristic ingredients. CRP possesses wide pharmacological effects such as having a beneficial effect on the cardiovascular, digestive, and respiratory systems, antitumor, antioxidant, and anti-inflammatory properties; and a protective effect on the liver and nerve. Moreover, hesperidin is chosen as an indicator in the quantitative determination of CRP, and the quantity of aflatoxin in CRP must not exceed the standard limit mentioned in the pharmacopoeia. In brief, CRP has a warming nature, and hence, it can be used in harmony with a lot of medicines. CRP not only exhibits its effects individually but also aids other medicines exhibit a better effect. CRP can be consumed with tea, food, alcohol, and medicine. Irrespective of the form it is being consumed, CRP not only shows a synergistic effect but also has strengths on its own. Modern pharmacological studies have demonstrated that CRP has marked bioactivities, especially on the diseases of the digestive and respiratory systems. The bioactivities of CRP are useful for its clinical application and provide prospects for the development of drugs as well as food and health products for people. Although CRP is a commonly used drug in the traditional Chinese herbal prescription, there is an urgent need for further research on its synergistic effect with other herbs based on the compatibility theory of TCM, which would further increase our understanding on the compatibility theory of TCM.

List, Johann-Mattis; Greenhill, Simon J; Gray, Russell D

2017-01-01

The amount of data from languages spoken all over the world is rapidly increasing. Traditional manual methods in historical linguistics need to face the challenges brought by this influx of data. Automatic approaches to word comparison could provide invaluable help to pre-analyze data which can be later enhanced by experts. In this way, computational approaches can take care of the repetitive and schematic tasks leaving experts to concentrate on answering interesting questions. Here we test the potential of automatic methods to detect etymologically related words (cognates) in cross-linguistic data. Using a newly compiled database of expert cognate judgments across five different language families, we compare how well different automatic approaches distinguish related from unrelated words. Our results show that automatic methods can identify cognates with a very high degree of accuracy, reaching 89% for the best-performing method Infomap. We identify the specific strengths and weaknesses of these different methods and point to major challenges for future approaches. Current automatic approaches for cognate detection-although not perfect-could become an important component of future research in historical linguistics.

Using a newly compiled database of expert cognate judgments across five different language families, we compare how well different automatic approaches distinguish related from unrelated words. Our results show that automatic methods can identify cognates with a very high degree of accuracy, reaching 89% for the best-performing method Infomap. We identify the specific strengths and weaknesses of these different methods and point to major challenges for future approaches. Current automatic approaches for cognate detection—although not perfect—could become an important component of future research in historical linguistics. PMID:28129337

Islam, mental health and law: a general overview.

PubMed

Tzeferakos, Georgios A; Douzenis, Athanasios I

Islam is the dominant religion in about 56 countries around the globe, and has more than 1.2 billion followers. Islam represents a holistic way of life, and according to a large proportion of its followers, the Islamic law or Shari'ah should prevail over secular law and should be implemented as state law. The etymological root of the word Shari'ah can be traced back to the harsh life in the desert and it means "pathway to be followed" or "path to the water hole," since the water was the basic element and preserver of life. At the dawn of its historical course and at its moral and ethical core, Islam introduced many interesting and innovative beliefs concerning the mentally ill. Islam underlines the moral necessity for the protection and care of the vulnerable individuals, as dictated by God himself. On the other hand, beliefs about "possession" and stigmatization influence the peoples' attitude against and apprehension of mental disorders. This strange admixture is reflected upon the status of the mental health services and corresponding legislation found in the different countries of the Islamic world.

Accessing Creativity: Jungian Night Sea Journeys, Wandering Minds, and Chaos.

PubMed

Rosen, Diane

2016-01-01

NDS theory has been meaningfully applied to the dynamics of creativity and psychology. These complex systems have much in common, including a broad definition of "product" as new order emerging from disorder, a new whole (etymologically, 'health') out of disintegration or destabilization. From a nonlinear dynamical systems perspective, this paper explores the far-from-equilibrium zone of creative incubation: first in the Jungian night sea journey, a primordial myth of psychological and creative transformation; then in the neuroscience of mind wandering, the well-spring of creative ideation within the larger neural matrix. Finally, chaos theory grounds the elusive subject of creativity, modeling chaotic generation of idea elements that tend toward strange attractors, combine unpredictably, and produce change by means of tension between opposites, particularly notes consciousness (light) and the poetic unconscious (darkness). Examples from my own artwork illustrate this dialectical process. Considered together, the unconscious mythic sea journey, the unknowing wandering mind, and the generative paradigm of deterministic chaos suggest conditions that facilitate creativity across disciplines, providing fresh indications that the darkness of the unknown or irrational is, paradoxically, the illuminative source and strength of creativity.

Phytoplankton invasions: comments on the validity of categorizing the non-indigenous dinoflagellates and diatoms in European seas.

PubMed

Gómez, Fernando

2008-04-01

The validity of categorizing the diatoms and dinoflagellates reported in the literature as non-indigenous phytoplankton in the European Seas was investigated. Species that are synonymous are often included as separate species (Gessnerium mochimaensis=Alexandrium monilatum, Gymnodinium nagasakiense=Karenia mikimotoi, Pleurosigma simonsenii=P. planctonicum), while other species names are synonyms of cosmopolitan taxa (Prorocentrum redfieldii=P. triestinum, Pseliodinium vaubanii=Gyrodinium falcatum, Gonyaulax grindleyi=Protoceratium reticulatum, Asterionella japonica=Asterionellopsis glacialis). Epithets of an exotic etymology (i.e. japonica, sinensis, indica) imply that a cosmopolitan species may be non-indigenous, and several taxa are even considered as non-indigenous in their type locality (Alexandrium tamarense and A. pseudogoniaulax). The records of Alexandrium monilatum, A. leei and Corethron criophilum are doubtful. Cold or warm-water species expand their geographical ranges or increase their abundances to detectable levels during cooling (Coscinodiscus wailesii) or warming periods (Chaetoceros coarctatus, Proboscia indica, Pyrodinium bahamense). These are a few examples of marginal dispersal associated with climatic events instead of species introductions from remote areas. The number of non-indigenous phytoplankton species in European Seas has thus been excessively inflated.

A majority of Africans rely on traditional medicine as the primary form of health care. Yet most traditional medicine products have a short shelf life, especially for water-based formulations such as macerations, infusions and decoctions. Indeed, many of these water extracts become unfit for human consumption after five to seven days of conservation either because of the degradation or toxicity of active components, and/or the growth of pathogenic organisms. The purpose of this study was to describe and apply a new approach for the development of an improved traditional medicine (ITM) that is cheap, very efficient, not toxic, and easy to produce, and that can be conserved for a longer time without a significant loss of activity. Hence, Laportea ovalifolia was selected from an ethnobotanical prospection in all regions of Cameroon, and was used to prepare an oral hypoglycemic product. This preparation required 9 steps focused on the characterization of the plant species, and the standardization of the ethnopharmacological preparation by a multidisciplinary team of scientists with expertise in botany, ecology, pharmacognosy and pharmacology. Resultantly, four galenic formulations of hypoglycemic medications were produced. A relationship between these four formulations was described as follow: One spoon of oral suspension (10 ml)=one sachet of powder=2 tablets=3 capsules. Hence, our research provides new insight into a drug discovery approach that could alleviate the major problems affecting traditional medicine and enhance its effectiveness in addressing health care in developing and undeveloped countries.

The ethnomedicinal values of plants form the basis of the herbal drug industry. India has contributed its knowledge of traditional system medicines (Ayurveda and Siddha) to develop herbal medicines with negligible side effects. The World Health Organization has also recognized the benefits of drugs developed from natural products. Abutilon indicum, Hibiscus sabdariffa, Sida acuta and Sida rhombifolia are ethnomedicinal plants of Malvaceae, commonly used in Indian traditional system of medicines. Traditionally these plants were used in the form of extracts/powder/paste by tribal populations of India for treating common ailments like cough and cold, fever, stomach, kidney and liver disorders, pains, inflammations, wounds, etc. The present review is an overview of phytochemistry and ethnopharmacological studies that support many of the traditional ethnomedicinal uses of these plants. Many phytoconstituents have been isolated from the four ethnomedicinal plants and some of them have shown pharmacological activities that have been demonstrated by in vivo and/or in vitro experiments. Ethnomedicinal uses, supported by scientific evidences is essential for ensuring safe and effective utilization of herbal medicines. PMID:29057840

The genus Erythrina comprises more than 100 species, widely distributed in tropical and subtropical areas. In Africa, 31 wild species and 14 cultivated species have been described. In sub-Saharan Africa, Erythrina species are used to treat frequent parasitic and microbial diseases, inflammation, cancer, wounds. The rationale of these traditional uses in African traditional medicine was established by screening several species for biological activities. Promising activities were found against bacteria, parasites (Plasmodium), human and phytopathogenic fungi, some of which were multidrug resistant (MDR) micro organisms. Some species also exhibited antioxidant, anti-inflammatory activities and enzymes inhibitory properties. Most of the species chemically investigated were reported to contain flavanones, prenylated isoflavones, isoflavanones and pterocarpans. Some phytochemicals (vogelin B, vogelin C, isowightcone, abyssinin II, derrone) were the active principles as antibacterials, antifungals, antiplasmodials and inhibitors of enzyme borne diseases (PTP1B, HIV protease, DGAT). This review highlights the important role of Erythrina species as sources of lead compounds or new class of phytotherapeutic agents for fighting against major public health (MDR infections, cancer, diabetes, obesity) in sub-Saharan Africa.

The genus Berberis (Berberidaceae) includes about 500 species worldwide, some of which are widely cultivated in the north-eastern regions of Iran. This genus consists of spiny deciduous evergreen shrubs, characterized by yellow wood and flowers. The cultivation of seedless barberry in South Khorasan goes back to two hundred years ago. Medicinal properties for all parts of these plants have been reported, including: Antimicrobial, antiemetic, antipyretic, antioxidant, anti-inflammatory, anti-arrhythmic, sedative, anti-cholinergic, cholagogic, anti-leishmaniasis, and anti-malaria. The main compounds found in various species of Berberis, are berberine and berbamine. Phytochemical analysis of various species of this genus revealed the presence of alkaloids, tannins, phenolic compounds, sterols and triterpenes. Although there are some review articles on Berberis vulgaris (as the most applied species), there is no review on the phytochemical and pharmacological activities of other well-known species of the genus Berberis. For this reason, the present review mainly focused on the diverse secondary metabolites of various species of this genus and the considerable pharmacological and biological activities together with a concise story of the botany and cultivation.

A microscopic technique combining spectral confocal laser scanning microscopy with a lipophilic fluorescent dye, Nile red, which can emit trans-polyisoprene specific fluorescence, was developed, and unmixed images of synthesized trans-polyisoprene in situ in Eucommia ulmoides were successfully obtained. The images showed that trans-polyisoprene was initially synthesized as granules in non-articulated laticifers that changed shape to fibers during laticifer maturation. Non-articulated laticifers are developed from single laticiferous cells, which are differentiated from surrounding parenchyma cells in the cambium. Therefore, these observations suggested that trans-polyisoprene biosynthesis first started in laticifer cells as granules and then the granules accumulated and fused in the inner space of the laticifers over time. Finally, laticifers were filled with the synthesized trans-polyisoprene, which formed a fibrous structure fitting the laticifers shape. Both trans- and cis-polyisoprene are among the most important polymers naturally produced by plants, and this microscopic technique combined with histological study should provide useful information in the fields of plant histology, bioindustry and phytochemistry.

Mango sap (latex) from four Indian varieties was studied for its composition. Sap was separated into non-aqueous and aqueous phases. Earlier, we reported that the non-aqueous phase contained mainly mono-terpenes having raw mango aroma (Phytochemistry 52 (1999) 891). In the present study biochemical composition of the aqueous phase was studied. Aqueous phase contained little amount of protein (2.0-3.5 mg/ml) but showed high polyphenol oxidase (147-214 U/mg protein) and peroxidase (401-561 U/mg protein) activities. It contained low amounts of polyphenols and protease activities. On native PAGE, all the major protein bands exhibited both polyphenol oxidase and peroxidase activities. Both polyphenol oxidase and peroxidase activities were found to be stable in the aqueous phase of sap at 4 degrees C. Sap contained large amount of non-dialyzable and non-starchy carbohydrate (260-343 mg/ml sap) which may be responsible for maintaining a considerable pressure of fluid in the ducts. Thus, the mango sap could be a valuable by-product in the mango industry as it contains some of the valuable enzymes and aroma components.

In India, the term “Amarkand” is commonly used for around 30 different plant species belonging to genus Eulophia (Orchidaceae). This single local name Amarkand to different taxonomical species creates uncertainty about its ethnomedical and nutritional claims. In the present article, we have reviewed available literature regarding ethnopharmacology, phytochemistry, taxonomy, nutritional, and pharmacological studies of different Amarkand species. The literature was searched using Google Scholar, PubMed, Scopus, and Web of Science databases. Some textbooks and reference books were also used to collect information about traditional and ethnopharmacological records. Amarkand species have been used as a remedy for the treatment of various diseases such as diarrhea, stomach pain, rheumatoid arthritis, cancer, asthma, bronchitis, sexual impotency, tuberculosis, and so on. Nutritionally, Amarkand is considered as an excellent food for children and convalescents. Recent studies confirm antioxidant, anti-inflammatory, anti-diarrheal, and so forth activities to Amarkand species. These species are reported to possess various phytoconstituents such as flavonoids, terpenoids, and phenanthrene derivatives. The present review will help to understand overall ethnopharmacology, nutritional aspects, and taxonomy of Amarkand species. PMID:27104043

Oxidative stress plays a key role in the pathogenesis of different serious chronic diseases such as cancer, diabetes, cardiovascular and neurodegenerative disorders, etc. Recent research has been focused on the beneficial role of dietary antioxidants against oxidative stress both under in vitro and in vivo conditions. Theobroma cacao L. (cacao tree) is an evergreen tree which is native to South America. It is a plant of great economic importance and its seeds are commonly used to produce cocoa powder and chocolate. In addition to its uses in food industry, cocoa is a rich source of polyphenolic antioxidants. There is a plethora of in vitro and in vivo studies that report cocoa antioxidant capacity. The protective activity of cocoa seems to be due to its phytochemical constituents, especially catechins. However, bioavailability of cocoa polyphenolic constituents following oral administration is very low (nanomolar concentrations). In the present paper, we critically reviewed the available literature on the antioxidant and free radical scavenging activities of cocoa and its polyphenolic constituents. In addition to these, we provide brief information about cultivation, phytochemistry, bioavailability and clinical impacts of cocoa.

Investigation on the medical ethnobotany of the Q’eqchi Maya of Livingston, Izabal, Guatemala, was undertaken in order to explore Q’eqchi perceptions, attitudes, and treatment choices related to women’s health. Through participant observation and interviews a total of 48 medicinal plants used to treat conditions related to pregnancy, childbirth, menstruation, and menopause were collected and identified followed by the evaluation of 20 species in bioassays relevant to women’s health. Results of field interviews indicate that Q’eqchi cultural perceptions affect women’s health experiences while laboratory results (estrogen receptor and serotonin receptor binding assays) provide a scientific correlation between empirical medicinal plant use among the Q’eqchi and the pharmacological basis for their administration. These data can contribute to Guatemala’s national effort to promote a complementary relationship between traditional Maya medicine and public health services and can serve as a basis for further pharmacology and phytochemistry on Q’eqchi medicinal plants for the treatment of women’s health conditions.

Diabetes mellitus, a clinical syndrome characterized by hyperglycemia due to deficiency of insulin, is a disease involving the endocrine pancreas and causes considerable morbidity and mortality in the world. In Nigeria, many plants, especially those implicated in herbal recipes for the treatment of diabetes, have not been screened for their elemental constituents while information on phytochemistry of some of them is not available. There is therefore the need to document these constituents as some of these plants are becoming increasingly important as herbal drugs or food additives. The accelerator-based technique PIXE, using the 1.8 MeV collimated proton beam from the 2.5 MV AN 2000 Van de Graaff accelerator at INFN, LNL, Legnaro (Padova) Italy, was employed in the determination of the elemental constituents of these anti-diabetic medicinal plants. Leaves of Gardenia ternifolia, Caesalpina pulcherrima, Solemostenon monostachys, whole plant of Momordica charantia and leaf and stem bark of Hunteria umbellata could be taken as vegetables, neutraceuticals, food additives and supplements in the management of diabetes. However, Hexabolus monopetalus root should be used under prescription.

Several species of the stapeliads, a group of stem succulents belonging to the family Apocynaceae are reported on in the ethnopharmacology literature and many of the references relate to their use as food plants. The most important of these plants is Hoodia gordonii, which during the past decade has risen from an almost forgotten spiny, desert plant to an important commercial appetite-suppressant herbal. The aim of this review is to summarize the botany, ethnopharmacology and phytochemistry of Hoodia gordonii. Journal articles and books were used to collect information on Hoodia gordonii and related species. Many books and articles documented the use of stapeliad species as food plants and earlier references refer to the use Hoodia species as a thirst quencher. However, prior to the publication of the patent application, only a single reference referring to the use of Hoodia pilifera as appetite suppressant was found. The structures of several steroid glycosides isolated from Hoodia gordonii are summarized. Hoodia gordonii illustrates how a combination of ethnobotany and scientific research can lead to a commercial product which can greatly benefit the indigenous people.

A liquid chromatography-mass spectrometry method was developed for the simultaneous separation, and determination of natural compounds including phenolic acids and flavonoids in the leaves of Hibiscus sabdariffa. By analyzing the UV and MS data, and comparison with authenticated standards, 10 polyphenols including neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, quercetin, kaempferol and their glycosides were identified together with 5-(hydroxymethyl)furfural. Major constituents in the leaves of 25 different populations from worldwide accessions were quantified and compared with each other. The total phenolic content of each accession was determined using Folin-Ciocalteu assay, ranging from 18.98 ± 2.7 to 29.9 ± 0.5 mg GAE/g. Their in vitro antioxidant activities were measured by ABTS radical cation decolorization assay, varying from 17.5 to 152.5 ± 18.8 μmol Trolox/g. After the treatment of H. sabdariffa leaf extract, the reduction of LPS-induced NO production dose-dependently in RAW 264.7 cell indicates the extract's potential anti-inflammatory activity.

Angelica sinensis (Oliv.) Diels, known as Dang Gui (in Chinese), is a traditional medicinal and edible plant that has long been used for tonifying, replenishing, and invigorating blood as well as relieving pain, lubricating the intestines, and treating female irregular menstruation and amenorrhea. A. sinensis has also been used as a health product and become increasingly popular in China, Japan, and Korea. This paper aims to provide a systemic review of traditional uses of A. sinensis and its recent advances in the fields of phytochemistry, analytical methods and toxicology. In addition, possible trends, therapeutic potentials, and perspectives for future research of this plant are also briefly discussed. An extensive review of the literature was conducted, and electronic databases including China National Knowledge Infrastructure, PubMed, Google Scholar, Science Direct, and Reaxys were used to assemble the data. Ethnopharmacological literature and digitalised sources of academic libraries were also systematically searched. In addition, information was obtained from local books and The Plant List (TPL, www.theplantlist.org). This study reviews the progress in chemical analysis of A. sinensis and its preparations. Previously and newly established methods, including spectroscopy, thin-layer chromatography (TLC), gas chromatography (GC), high-performance liquid chromatography (HPLC), ultra-performance liquid chromatography(UPLC), and nuclear magnetic resonance analysis (NMR), are summarized. Moreover, identified bioactive components such as polysaccharides, ligustilide and ferulic acid were reviewed, along with analytical methods for quantitative and qualitative determination of target analytes, and fingerprinting authentication, quality evaluation of A. sinensis, and toxicology and pharmacodynamic studies. Scientific reports on crude extracts and pure compounds and formulations revealed a wide range of pharmacological activities, including anti-inflammatory activity, antifibrotic action, antispasmodic activity, antioxidant activities, and neuroprotective action, as well as cardio- and cerebrovascular effects. Within the published scientific literature are numerous reports regarding analytical methods that use various chromatographic and spectrophotometric technologies to monitor various types of components with different physicochemical properties simultaneously. This review discusses the reasonable selection of marker compounds based on high concentrations, analytical methods, and commercial availabilities with the goal of developing quick, accurate, and applicable analytical approaches for quality evaluation and establishing harmonised criteria for the analysis of A. sinensis and its finished products. Compounds isolated from A. sinensis are abundant sources of chemical diversity, from which we can discover active molecules. Thus, more studies on the pharmacological mechanisms of the predominant active compounds of A. sinensis are needed. In addition, given that A. sinensis is one of the most popular traditional herbal medicines, its main therapeutic aspects, toxicity, and adverse effects warrant further investigation in the future.

The botanical origin of a Chinese crude drug Ma-huang in ancient China and the origin of Japanese Ma-huang were herbologically studied. The results showed that the plants of Ephedra sinica Stapf, E. intermedia Schrenk & C. A. Meyer and E. equisetina Bunge were used as Ma-huang in China, and the first species was considered to be of high quality. The characters of Mao-zhou Ma-huang and Tong-zhou Ma-huang printed in Tu-jing-ben-cao, published in the Song Dynasty in China, were identified as E. likiangensis Florin and E. intermedia, respectively, and both species were recognized as excellent Ma-huang in the Ming Dynasty. The word origin of Katsune-kusa, the Japanese name for Ma-huang in the Heian Era, was etymologically considered as meaning the plant having reddish brown roots. In Japan, the plant of Equisetum ramosissimum Desf. var.japonicum Milde, of the family Equisetaceae, was substituted for Ma-huang in the middle of Edo Era, and it was designated that this action was based on the confusion of Ephedra plants and Equisetum plants those days in China.

History of the term prostate.

Josef Marx, Franz; Karenberg, Axel

We comprehensively review the history of the word "prostate" and related terms from 600 BC to the present. Both medical and non-medical ancient texts were searched to clarify the term's etymology and use. Anatomy textbooks of the 16th through the 18th century were analyzed to identify descriptions, illustrations and various expressions used by contemporary authors to designate the prostate. In ancient Greek the masculine term "prostatēs" meant "president" and was exclusively used in a non-medical sense. It was not until the Renaissance that anatomists discovered the organ naming it "glandulous body." In 1600 the French physician du Laurens introduced the metaphoric denomination "prostatae." However he and his contemporaries misinterpreted the history of the organ and the term, choose the wrong gender when translating it into Latin, and believed that it designated a double organ. Only in the 1800s was this anatomical error corrected while the grammatical one lived on. The history of the term "prostate" is a prime example of the difficulties with which the development of a precise urologic terminology had to struggle. At the same time this retrospective view provides a stimulus to avoid linguistic ambiguity in the future.

A number of designations for diseases, medicines and human body structures derive from classical mythology. To date, these eponyms have not been systematically investigated. This paper provides an overview of this fringe component of medical vocabulary, looks at the history of several terms and formulates hypotheses as to why such creative etymologies have come into being. In addition to relevant texts on ancient mythology, a variety of medical textbooks from the early modern period were analyzed. Between the 16th and the 20th centuries some 30 figures from Greek and Roman literature made their way into the terminology of medical sciences. A few of these expressions can be encountered in clinical use (e. g., Caput Medusae, Proteus, Oedipus complex) and remain official anatomical (atlas, Achilles tendon) or pharmaceutical nomenclature (atropine, morphine). The choice of these designations has often been similarity of form or analogies in function. Classical eponyms have gained acceptance on account of their succinctness, conciseness and scholarly veneer. Finally, this vocabulary shares its origin with other relevant terminology. In clinical classes, mythological designations can serve as a point of departure for digressions into literary, art and medical history in order to provide an understanding of cultural traditions and enhance education.

[The space of passion].

Gori, R

1990-01-01

The figures and speech of passion are clinically polymorphous and heterogeneous: from the baroque of the mystical ecstasy, the iconophily of religious and political ideologies, the collector's usual fetishism and the paranoiac insanity of hatred to the passions of knowing and loving. These are at the same time a passion for life as well as for self-destruction, for showing oneself as well for not knowing oneself, for representing oneself as well as for non representing oneself. Passion bares the impossible of mourning, its real point that gives a boost to the continual work. Passion confronts us to the essence of the being, to its fundamental distress. The being, whose shadow is projecting itself on the object of the passion, gives a name and a face to that object, and receives back its marks. That explains why passion is always accompanied by suffering. Moreover, passion is suffering according to its etymology: until the XVIth century, the word "passionate" meant somebody who suffered physically. The nature of the object of the passion (a relic, a part of a sentence, an indication, the track of an object or any other subject) changes nothing to the structure of the speech of passion.

Space for the Prisoner's Point of View.

PubMed

Haupt, Laura

2017-03-01

The lead article in this issue discusses a potentially free metaphorical space-that of decision-making-within the confines, tangible and intangible, of life in jail or prison. By interviewing prisoner-participants from six clinical studies, Paul Christopher and colleagues sought to find out how these men and women would answer open-ended questions about their decision to enroll in the research. What the interviewers heard was that none saw themselves as having been inappropriately pressured to do so. In fact, a significant percentage of the prisoners described being dissuaded from participating in the studies. The authors therefore advise that unfair exploitation poses the more relevant research risk to contemporary prisoners in the United States than does coercion, and they encourage investigations into whether prisoners are unfairly restricted or discouraged from joining clinical studies. Although Keramet Reiter makes no reference to etymology in her commentary responding to the article, her argument suggests that the roots of "coerce"-the Latin for "shut up" or "enclose"-remain relevant. Reiter argues that, under current conditions, the people shut up in prisons in the United States cannot make an unfettered choice to join a clinical trial. © 2017 The Hastings Center.

[The Arabic pharmacology and the introduction to Europe: the background of the Arabic pharmacology - the legacy from Greece].

PubMed

Provençal, P

2001-01-01

When the Arabic-Islamic medicine evolved partly as a consequence of the wave of translations from mainly Greek medical books to Arabic in the 9th century the pharmacological works, which were available, were also translated. The books of Dioscurides and Galen on pharmacological matters became the decisive books of pharmacological translated literature and they formed the basis of the pharmacological understanding in the subsequent extensive literature on pharmacognosy and pharmacology written in Arabic. Nevertheless the Arabs united these two disciplines in a regular pharmacy and they evolved it as an independent discipline, which although attached to medicine was regarded as having its own praxis. The physicians and scientists rationalized and systematized their knowledge of medicinal plants and drugs and extended their knowledge by using original observations and research. Many books on medicaments were written, both as materia medica, i.e. records on simple drugs, and dispensatories, i.e. books on compounded drugs. These two kinds of books were always written separately as they were seen by the Arabs themselves as pertaining to two different subdisciplines, which meant that they were separated too in independent chapters or books in general Arabic works on medicine. When the extensive translations of Arabic medical literature to Latin took place in Italy and Spain in the 11th and 12th centuries, the Arabic pharmacological literature was of course also translated, and its decisive influence on later medieval European medical writings is easy to demonstrate. In the 18th century Peter Forsskaal was one of the first Europeans in the modern scientific tradition to collect and make notes on drugs used in Cairo and in Yemen.

Prof. Shoji Shibata (1916-2016) left behind remarkable achievements in the field of the history of pharmacy. Among those, the scientific survey on medicines preserved in Shōsō-in, globally known as the World Cultural Heritage, is of particular interest, drawing wide attention from scholars to the general public. Its most spectacular and also shocking study in the field of pharmacognosy will be the one on the true origin of Kōboku (Houpu) that seems quite ordinary from its name. Prof. Shibata revealed that it is of juglandaceous origin that is completely different from what is known today under the same name. Juglandaceous Kōboku, which came into wide use in China at that time, was neither a homonym nor adulteration according to the pertinent description on this medicine in Chinese herbal books, and, furthermore, was regarded as authentic even at the Song Dynasty. In the Nara period of Japan, the name of Kōboku is not found except for the archives preserved in Shōsō-in, while the name of Hoogashiwa, an old name of Hoonoki (Magnolia obovata), appears only in "Man'yōshū", Japan's oldest anthology. Therefore, Hoonoki was not recognized as Kōboku at that time. Interestingly, this fact is also reflected in "Man'yōshū". In the epigraph of two poems including Hoonoki, the Japanese name is used instead of the Chinese name that should be employed in principle. The historical circumstances of "Shōsō-in Medicines" will also be outlined with elaborate and reliable evidence.

Moringa oleifera is an interesting plant for its use in bioactive compounds. In this manuscript, we review studies concerning the cultivation and production of moringa along with genetic diversity among different accessions and populations. Different methods of propagation, establishment and cultivation are discussed. Moringa oleifera shows diversity in many characters and extensive morphological variability, which may provide a resource for its improvement. Great genetic variability is present in the natural and cultivated accessions, but no collection of cultivated and wild accessions currently exists. A germplasm bank encompassing the genetic variability present in Moringa is needed to perform breeding programmes and develop elite varieties adapted to local conditions. Alimentary and medicinal uses of moringa are reviewed, alongside the production of biodiesel. Finally, being that the leaves are the most used part of the plant, their contents in terms of bioactive compounds and their pharmacological properties are discussed. Many studies conducted on cell lines and animals seem concordant in their support for these properties. However, there are still too few studies on humans to recommend Moringa leaves as medication in the prevention or treatment of diseases. Therefore, further studies on humans are recommended.

Sugarcane (Saccharum officinarum Linn.) is an important perennial grass of Poaceae family, indigenous to tropical South Asia and Southeast Asia. It is cultivated worldwide due to the economical and medicinal value of its high yielding products. Sugarcane juice is well known as a raw material for the production of refined sugar and its wax is considered as a potential substitute for the expensive carnauba wax, which is of cosmetic and pharmaceutical interest. Refined sugar is the primary product of sugarcane juice, but during its processing, various other valuable products are also obtained in an unrefined form, such as, brown sugar, molasses, and jaggery. Sugarcane juice is widely used in India in the treatment of jaundice, hemorrhage, dysuria, anuria, and other urinary diseases. Herein, we have summarized the different phytoconstituents and health benefits of sugarcane and its valuable products. The phytochemistry of sugarcane wax (obtained from the leaves and stalks of sugarcane), leaves, juice, and its products has revealed the presence of various fatty acid, alcohol, phytosterols, higher terpenoids, flavonoids, -O- and -C-glycosides, and phenolic acids. The future prospective of some of the sugarcane products has been discussed, which needs a phytopharmacological study and has a great potential to be a valuable medicinal product. PMID:26009693

Elephantorrhiza elephantina is used in southern Africa as traditional remedy for a wide range of human diseases and ailments including dermatological diseases, gastrointestinal system disorders, sexual dysfunction, sexually transmitted infections, and wounds. The rhizome decoction of E. elephantina is widely used by small-scale farmers in Botswana and South Africa as ethnoveterinary medicine for cattle, goats, horses, pigs, poultry, and sheep. Several classes of phytochemical compounds including anthocyanidins, anthraquinones, esters, fatty acids, phenolic compounds, flavonoids, glycosides, polysterols, saponins, sugars, tannins, and triterpenoids have been isolated from E. elephantina. Scientific studies on E. elephantina indicate that it has a wide range of biological activities including anthelmintic, antibacterial, antifungal, anti-inflammatory and antinociceptive, antiplasmodial, antioxidant, antibabesial, and antirickettsial activities. Elephantorrhiza elephantina is a valuable source of traditional medicine in southern Africa that it is worth additional research attention because of its wide ethnomedicinal applications and promising biological activities. However, the current health-related information on E. elephantina is not sufficiently explored as diverse studies on its chemical and pharmacological activities are required to understand its mechanism of action and to characterize the metabolites responsible for these activities.

From the 16th up into the 18th century botanical and medicinal knowledge in Europe was documented and spread in magnificently illustrated herbals. For the most part modern science has neglected this source of knowledge and old remedies have not been systematically evaluated pharmacologically. Rheumatic disorders and chronic inflammatory and degenerative diseases of the musculoskeletal system were chosen in an attempt to discuss remedies described in the old herbals in the viewpoint of modern science. Five of the most important European herbals of the 16th and 17th century were searched for terms related to rheumatic diseases, and plants and recipes described for their treatment. An extensive search of the scientific data banks Medline and SciFinder scholar was done to find recent results concerning the phytochemistry and possible antiphlogistic activities of the plants. Sixty-three plants were identified in the herbals for this indication. More than half of them have shown in vitro or in vivo antiphlogistic activities. European herbals may be a valuable source of information for the selection of plants for focussed screening programmes. Information contained in these herbals should be explored in a systematic manner.

As aboriginal sources of medications, medicinal plants are used from the ancient times. Andrographis paniculata is one of the highly used potential medicinal plants in the world. This plant is traditionally used for the treatment of common cold, diarrhoea, fever due to several infective cause, jaundice, as a health tonic for the liver and cardiovascular health, and as an antioxidant. It is also used to improve sexual dysfunctions and serve as a contraceptive. All parts of this plant are used to extract the active phytochemicals, but the compositions of phytoconstituents widely differ from one part to another and with place, season, and time of harvest. Our extensive data mining of the phytoconstituents revealed more than 55 ent-labdane diterpenoids, 30 flavonoids, 8 quinic acids, 4 xanthones, and 5 rare noriridoids. In this review, we selected only those compounds that pharmacology has already reported. Finally we focused on around 46 compounds for further discussion. We also discussed ethnobotany of this plant briefly. Recommendations addressing extraction process, tissue culture, and adventitious rooting techniques and propagation under abiotic stress conditions for improvement of phytoconstituents are discussed concisely in this paper. Further study areas on pharmacology are also proposed where needed. PMID:25950015

Plantago major has been used widely since ancient times, to manage a wide range of diseases including constipation, coughs and wounds. The aim of this study is to review the traditional application, botanical characterization, pharmacological activities, phytochemistry effects and toxicity of Plantago major. In this review study, medicinal properties of Plantago major are collected from credible pharmacopeias, textbooks of traditional Persian medicine (TPM) belonging to the 10-18th century AD, such as "The Canon of Medicine", "Makhzan-Al- Advia" and so on. Moreover, electronic databases including Scopus, Medline and Web of science were explored for this purpose. Plantago major has been prescribed in various forms such as roasted seeds, decoction, syrup, liniment, gargle, rectal enema, vaginal suppository, eye and nasal drop for each illness by TPM scholars. Some of its traditional properties including wound healing, antipyretic, antitussive, anti-infective, anti-hemorrhagic, anti-inflammatory, diuretic, laxative, astringent and hemostatic have been confirmed in recent researches. Phytochemical investigations showed that Plantago major contains volatile compounds, triterpenoids, phenolic acids and flavonoids. Modern pharmacological studies have proven some of the traditional applications of Plantago major. Nevertheless, more investigations are required on this plant, because it has the potential to be used to produce various natural medications.

Recent Advances and Uses of Grape Flavonoids as Nutraceuticals

Grape is one of the oldest fruit crops domesticated by humans. The numerous uses of grape in making wine, beverages, jelly, and other products, has made it one of the most economically important plants worldwide. The complex phytochemistry of the berry is characterized by a wide variety of compounds, most of which have been demonstrated to have therapeutic or health promoting properties. Among them, flavonoids are the most abundant and widely studied, and have enjoyed greater attention among grape researchers in the last century. Recent studies have shown that the beneficial health effects promoted by consumption of grape and grape products are attributed to the unique mix of polyphenolic compounds. As the largest group of grape polyphenols, flavonoids are the main candidates considered to have biological properties, including but not limited to antioxidant, anti-inflammatory, anti-cancer, antimicrobial, antiviral, cardioprotective, neuroprotective, and hepatoprotective activities. Here, we discuss the recent scientific advances supporting the beneficial health qualities of grape and grape-derived products, mechanisms of their biological activity, bioavailability, and their uses as nutraceuticals. The advantages of modern plant cell based biotechnology as an alternative method for production of grape nutraceuticals and improvement of their health qualities are also discussed. PMID:24451310

Tea (Camellia sinensis L.) is the most popular, flavored, functional, and therapeutic non-alcoholic drink consumed by two-thirds of the world's population. Black tea leaves are reported to contain thousands of bioactive constituents such as polyphenols, amino acids, volatile compounds, and alkaloids that exhibit a range of promising pharmacological properties. Due to strong antioxidant property, black tea inhibits the development of various cancers by regulating oxidative damage of biomolecules, endogenous antioxidants, and pathways of mutagen and transcription of antioxidant gene pool. Regular drinking of phytochemicals-rich black tea is linked to regulate several molecular targets, including COX-2, 5-LOX, AP-1, JNK, STAT, EGFR, AKT, Bcl2, NF-κB, Bcl-xL, caspases, p53, FOXO1, TNFα, PARP, and MAPK, which may be the basis of how dose of black tea prevents and cures cancer. In vitro and preclinical studies support the anti-cancer activity of black tea; however, its effect in human trails is uncertain, although more clinical experiments are needed at molecular levels to understand its anti-cancer property. This review discusses the current knowledge on phytochemistry, chemopreventive activity, and clinical applications of black tea to reveal its anti-cancer effect.

Vernal freeze damage and genetic variation alter tree growth, chemistry, and insect interactions.

Anticipated consequences of climate change in temperate regions include early spring warmup punctuated by intermittent hard freezes. Warm weather accelerates leaf flush in perennial woody species, potentially exposing vulnerable young tissues to damaging frosts. We employed a 2 × 6 randomized factorial design to examine how the interplay of vernal (springtime) freeze damage and genetic variation in a hardwood species (Populus tremuloides) influences tree growth, phytochemistry, and interactions with an insect herbivore (Chaitophorus stevensis). Acute effects of freezing included defoliation and mortality. Surviving trees exhibited reduced growth and altered biomass distribution. Reflushed leaves on these trees had lower mass per area, lower lignin concentrations, and higher nitrogen concentrations, altered chemical defence profiles, and supported faster aphid population growth. Many effects varied among plant genotypes and were related with herbivore performance. This study suggests that a single damaging vernal freeze event can alter tree-insect interactions through effects on plant growth and chemistry. Differential responses of various genotypes to freeze damage suggest that more frequent vernal freeze events could also influence natural selection, favouring trees with greater freeze hardiness, and more resistance or tolerance to herbivores following damage. © 2017 John Wiley & Sons Ltd.

Eight essential oils (EOs) as well as 13 single terpenes were studied for their nematicidal activity against Meloidogyne incognita , for three immersion periods (24, 48, and 96 h). The EOs were isolated from eight Greek Lamiaceae species: Melissa officinalis , Sideritis clandestina , Origanum dictamnus , Ocimum basilicum , Mentha pulegium , Origanum vulgare , Vitex agnus castus , and Salvia officinalis . The EOs nematicidal activity was correlated to their chemical composition as well as to the pure terpenes' activity tested individually. Clear dose and time response relationships were established. The EOs of O. vulgare, O. dictamnus, M. pulegium, and M. officinalis exhibited high nematicidal activity against M. incognita, and the EC(50) values (96 h) were calculated at 1.55, 1.72, 3.15, and 6.15 muL/mL, respectively. The activity of the nematicidal terpenes was found to decrease in the order l-carvone, pulegone, trans-anethole, geraniol, eugenol, carvacrol, thymol, terpinen-4-ol, and the respective EC(50) values (24 h) were calculated in the range of 115-392 mug/mL. Terpenes tested individually were more active than as components in EO, implementing antagonistic action.

The crucial medicinal plant Dalbergia odorifera T. Chen species belongs to genus Dalbergia, with interesting secondary metabolites, consisting of main classes of flavonoid, phenol, and sesquiterpene derivatives, as well as several arylbenzofurans, quinones, and fatty acids. Biological studies were carried out on extracts, fractions, and compounds from this species involved in cytotoxic assays; antibacterial, antioxidative, anti-inflammatory, antithrombotic, antiplatelet, antiosteosarcoma, antiosteoporosis, antiangiogenesis, and prostaglandin biosynthetic enzyme inhibition activities; vasorelaxant activities; alpha-glucosidase inhibitory activities; and many other effects. In terms of the valuable resources for natural new drugs development, D. odorifera species are widely used as medicinal drugs in many countries for treatment of cardiovascular diseases, cancer, diabetes, blood disorders, ischemia, swelling, necrosis, or rheumatic pain. Although natural products from this plant have been increasingly playing an important role in drug discovery programs, there is no supportive evidence to provide a general insight into phytochemical studies on D. odorifera species and biological activities of extracts, fractions, and isolated compounds. To a certain extent, this review deals with an overview of almost naturally occurring compounds from this species, along with extensive coverage of their biological evaluations. PMID:29348771

The Ranunculaceae genus Anemone (order Ranunculales), comprising more than 150 species, mostly herbs, has long been used in folk medicine and worldwide ethnomedicine. Various medicinal compounds have been found in Anemone plants, especially triterpenoid saponins, some of which have shown anti-cancer activities. Some Anemone compounds and extracts display immunomodulatory, anti-inflammatory, antioxidant, and antimicrobial activities. More than 50 species have ethnopharmacological uses, which provide clues for modern drug discovery. Anemone compounds exert anticancer and other bioactivities via multiple pathways. However, a comprehensive review of the Anemone medicinal resources is lacking. We here summarize the ethnomedical knowledge and recent progress on the chemical and pharmacological diversity of Anemone medicinal plants, as well as the emerging molecular mechanisms and functions of these medicinal compounds. The phylogenetic relationships of Anemone species were reconstructed based on nuclear ITS and chloroplast markers. The molecular phylogeny is largely congruent with the morphology-based classification. Commonly used medicinal herbs are distributed in each subgenus and section, and chemical and biological studies of more unexplored taxa are warranted. Gene expression profiling and relevant "omics" platforms could reveal differential effects of phytometabolites. Genomics, transcriptomics, proteomics, and metabolomics should be highlighted in deciphering novel therapeutic mechanisms and utilities of Anemone phytometabolites.

To explore the identity and phylogenetic relationships among the three medicinally important species of Sphaerostephanos from South India using isozymic profile. The young fronds were homogenized with 3.5 mL of ice-cold homogenizing buffer in a pre-chilled pestle and mortar. The supernatant was subjected to electrophoresis as described by Anbalagan poly acrylamide gel electrophoresis. Staining solutions for isoperoxidase was prepared as per Smila method for the detection of isoenzymes. A total of six different bands in five different positions with different molecular weight/Rf values and four active zones have been observed in the isoperoxidase enzyme system of Sphaerostephanos. Only one band with MW/Rf 0.399 is common to two different species i.e. Sphaerostephanos arbuscula (S. arbuscula) and Sphaerostephanos unitus (S. unitus). Among the remaining four bands, two bands (Rf. 0.23, 0.47) are present in Sphaerostephanos subtruncatus (S. subtruncatus) and one distinct band has been observed individually in S. arbuscula (Rf. 0.507) and S. unitus (Rf. 0.56). The present preliminary molecular study through isozymic analysis shows the identity of all the three species and the present results confirm distinctness of these three species based on macro-micromorphology, phytochemistry and cytology.

Borreria and Spermacoce species (Rubiaceae): A review of their ethnomedicinal properties, chemical constituents, and biological activities

Borreira and Spermacoce are genera of Rubiaceae widespread in tropical and subtropical America, Africa, Asia, and Europe. Based on its fruits morphology they are considered by many authors to be distinct genera and most others, however, prefer to combine the two taxa under the generic name Spermacoce. Whereas the discussion is still unclear, in this work they were considered as synonyms. Some species of these genera play an important role in traditional medicine in Africa, Asia, Europe, and South America. Some of these uses include the treatment of malaria, diarrheal and other digestive problems, skin diseases, fever, hemorrhage, urinary and respiratory infections, headache, inflammation of eye, and gums. To date, more than 60 compounds have been reported from Borreria and Spermacoce species including alkaloids, iridoids, flavonoids, terpenoids, and other compounds. Studies have confirmed that extracts from Borreria and Spermacoce species as well as their isolated compounds possess diverse biological activities, including anti-inflammatory, antitumor, antimicrobial, larvicidal, antioxidant, gastrointestinal, anti-ulcer, and hepatoprotective, with alkaloids and iridoids as the major active principles. This paper briefly reviews the ethnomedicinal uses, phytochemistry, and biological activities of some isolated compounds and extracts of both genera. PMID:22654404

Medicinal plants have long been utilized in traditional medicine and ethnomedicine worldwide. This review presents a glimpse of the current status of and future trends in medicinal plant genomics, evolution, and phylogeny. These dynamic fields are at the intersection of phytochemistry and plant biology and are concerned with the evolution mechanisms and systematics of medicinal plant genomes, origin and evolution of the plant genotype and metabolic phenotype, interaction between medicinal plant genomes and their environment, the correlation between genomic diversity and metabolite diversity, and so on. Use of the emerging high-end genomic technologies can be expanded from crop plants to traditional medicinal plants, in order to expedite medicinal plant breeding and transform them into living factories of medicinal compounds. The utility of molecular phylogeny and phylogenomics in predicting chemodiversity and bioprospecting is also highlighted within the context of natural-product-based drug discovery and development. Representative case studies of medicinal plant genome, phylogeny, and evolution are summarized to exemplify the expansion of knowledge pedigree and the paradigm shift to the omics-based approaches, which update our awareness about plant genome evolution and enable the molecular breeding of medicinal plants and the sustainable utilization of plant pharmaceutical resources.

Tasheva, Krasimira; Kosturkova, Georgina

2012-01-01

At present, more than 50 000 plant species are used in phytotherapy and medicine. About 2/3 of them are harvested from nature leading to local extinction of many species or degradation of their habitats. Biotechnological methods offer possibilities not only for faster cloning and conservation of the genotype of the plants but for modification of their gene information, regulation, and expression for production of valuable substances in higher amounts or with better properties. Rhodiola rosea is an endangered medicinal species with limited distribution. It has outstanding importance for pharmaceutical industry for prevention and cure of cancer, heart and nervous system diseases, and so forth. Despite the great interest in golden root and the wide investigations in the area of phytochemistry, plant biotechnology remained less endeavoured and exploited. The paper presents research on initiation of in vitro cultures in Rhodiola rosea and some other Rhodiola species. Achievements in induction of organogenic and callus cultures, regeneration, and micropropagation varied but were a good basis for alternative in vitro synthesis of the desired metabolites and for the development of efficient systems for micropropagation for conservation of the species.

Sudan folklore medicine is characterized by a unique combination of Islamic, Arabic, and African cultures. In poor communities, traditional medicine has remained as the most reasonable source of treatment of several diseases and microbial infections. Although the traditional medicine is accepted in Sudan, to date there is no updated review available, which focuses on most effective and frequently used Sudanese medicinal plants. Thus, this review aims to summarize the published information on the ethnobotanical uses of medicinal plants from Sudan, preparation methods, phytochemistry, and ethnopharmacology. The collected data demonstrate that Sudanese medicinal plants have been reported to possess a wide range of traditional medicinal uses including different microbial infections, gastrointestinal disorders, malaria, diabetes, rheumatic pain, respiratory system disorders, jaundice, urinary system inflammations, wounds, cancer, and different microbial infections. In most cases, the pharmacological studies were in agreement with traditional uses. Moreover, several bioactive compounds such as flavonoids, saponins, alkaloids, steroids, terpenes, tannins, fatty acids, and essential oils have been identified as active constituents. Although this review demonstrates the importance of ethnomedicine medicines in the treatment of several diseases in Sudan, further researches to validate the therapeutic uses and safety of these plants through phytochemical screening, different biological activity assays, and toxicological studies are still needed.

Rubiaceae family is a large family of 630 genera and about 13000 species found worldwide, especially in tropical and warm regions. These plants are not only ornamental but they are also used in African folk medicine to treat several diseases. Based on online published data and library bibliographic research, we herein reported accumulated information related to their traditional usages in sub-Saharan traditional medicine, their chemical composition and the screened pharmacological activities. Indeed, more than 60 species are used for more than 70 medicinal indications including malaria, hepatitis, eczema, oedema, cough, hypertension, diabetes and sexual weakness. Through biological screening following leads supplied with traditional healers, many of these plants exhibited antimalarial, antimicrobial, antihypertension, antidiabetic, antioxidant and anti-inflammatory activities. Bioactive compounds including indole alkaloids, terpenoids and anthraquinones have been isolated from these bioguided fractionation studies. It is evidence that great attention has been paid to species such as Nauclea latifolia, Morinda lucida, Mitragyna inermis and Crossopteryx febrifuga; however, several compounds should be waiting to be discovered since none of these plants has been systematically investigated for its biochemical composition. According the current global health context with the recrudescence of HIV, much effort should be oriented towards this virus when screening Rubiaceae.

Haddad, Renato; Milagre, Humberto M S; Catharino, Rodrigo Ramos; Eberlin, Marcos N

2008-04-15

On-spot detection and analyte characterization on thin-layer chromatography (TLC) plates is performed via ambient desorption/ionization and (tandem) mass spectrometry detection, that is, via easy ambient sonic spray ionization mass spectrometry (EASI-MS). As proof-of-principle cases, mixtures of semipolar nitrogenated compounds as well as pharmaceutical drugs and vegetable oils have been tested. The technique has also been applied to monitor a chemical reaction of synthetic importance. EASI is the simplest and gentlest ambient ionization technique currently available, assisted solely by N2 (or air). It uses no voltages, no electrical discharges; no UV or laser beams, and no high temperature and is most easily implemented in all API mass spectrometers. TLC is also the simplest, fastest, and most easily performed chromatographic technique. TLC plus EASI-MS therefore provide a simple and advantageous combination of chromatographic separation and sensitive detection of the TLC spots as well as on-spot MS or MS/MS characterization. The favorable characteristics of TLC-EASI-MS indicate advantageous applications in several areas such as drug and oil analysis, phytochemistry and synthetic chemistry, forensics via reliable counterfeit detection, and quality control.

Plants of the genus Cimicifuga have long been used as an ethnomedicine in China, Europe, and North America for its high medicinal value and health benefits. Their dried rhizomes are widely used for treating wind-heat headache, toothache, aphtha, sore throat, measles, spot poison, archoptosis, and uterine prolapse. In addition, it is used as a dietary supplement for preventing women menopausal symptoms and osteoporosis. This paper aims to provide up-to-date information on the genus Cimicifuga, including botanical characterization, medicinal resources, traditional medicinal uses, phytochemistry, quality control, pharmacological research as well as the toxicology. The possible structural-activity relationships and molecular mechanisms of the bioactive constituents are discussed in ways that contribute to the structural optimization and preclinical safety assessment for further drug design. The relevant information on Cimicifuga was collected from scientific databases (such as Google Scholar, PubMed, SciFinder Scholar, Science Direct, CNKI, Baidu Scholar, Web of Science, China Knowledge Resource Integrated Database), Chinese herbal classics, ethnobotanical books, PhD and MSc dissertations, Chinese Pharmacopoeia, published articles in peer-reviewed journals, local magazines, and unpublished materials. In addition, the Plant List (TPL, www.theplantlist.org) was also used to validate the scientific names and synonyms of this plant. The literature cited in this review dated from 1953 to 2017. The majority of chemical constituents of this plant include triterpenoid glycosides, phenylpropanoids, nitrogenous compounds, chromones, flavonoids and 4α-methyl steroid. Among them, the primary bioactive constituents are believed to be present in the triterpene glycoside fraction. To date, investigation of seven Cimicifuga spp. plants led to the identification of more than 457 compounds. Years of pharmacological research proved that the crude extracts and certain pure compounds obtained from Cimicifuga exhibited menopausal syndrome-treatment, anti-osteoporosis, antiviral, antitumor, antioxidant and antiangiogenic activities. On the other hand, Cimicifuga plant-induced toxicities of liver, cardiovascular, central and peripheral nervous systems have also been reported. Therefore, safety consideration should be placed into a high priority for herbal medicine Cimicifuga therapy in the early stages of development and clinical trials. This review presents information on botany, medicinal resources, and traditional medicinal history of some Cimicifuga plants. Modern pharmacology researchers have validated many traditional uses of Cimicifuga species. As the quality control and safety assessment of Cimicifuga plants is still incomplete, only a small part of the plant is permitted to be used as medicines. Expansion of medicinal resources in Cimicifuga is urgently needed to enable its full use. Currently research primarily focuses on the triterpenoid glycosides but there are many other types of compounds which may possess new biological activities however the systematic studies of these compounds are lacking. Extensive study is required on Cimicifuga plant before it can be fully used in clinics as a potent drug candidate. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

"Congo" red: out of Africa?

2001-02-01

Congo red is the essential histologic stain for demonstrating the presence of amyloidosis in fixed tissues. To the best of my knowledge, nothing has been written about why the stain is named "Congo." To understand the etymology and history of the Congo red histologic stain. Primary sources were consulted extensively, including 19th-century corporate documents, newspapers, legal briefs, patents, memoirs, and scientific papers. Sources were obtained from multiple university libraries and German corporate archives. To Europeans in 1885, the word Congo evoked exotic images of far-off central Africa known as The Dark Continent. The African Congo was also a political flashpoint during the Age of Colonialism. "Congo" red was introduced in Berlin in 1885 as the first of the economically lucrative direct textile dyes. A patent on Congo red was filed by the AGFA Corporation of Berlin 3 weeks after the conclusion of the well-publicized Berlin West Africa Conference. During these important diplomatic talks, German Chancellor Otto von Bismarck presided over a discussion of free trade issues in the Congo River basin. A challenge to AGFA's Congo red patent led to a precedent-setting decision in intellectual property law. The Congo red stain was named "Congo" for marketing purposes by a German textile dyestuff company in 1885, reflecting geopolitical current events of that time.

Resilience and disaster risk reduction: an etymological journey

Alexander, D. E.

2013-11-01

This paper examines the development over historical time of the meaning and uses of the term resilience. The objective is to deepen our understanding of how the term came to be adopted in disaster risk reduction and resolve some of the conflicts and controversies that have arisen when it has been used. The paper traces the development of resilience through the sciences, humanities, and legal and political spheres. It considers how mechanics passed the word to ecology and psychology, and how from there it was adopted by social research and sustainability science. As other authors have noted, as a concept, resilience involves some potentially serious conflicts or contradictions, for example between stability and dynamism, or between dynamic equilibrium (homeostasis) and evolution. Moreover, although the resilience concept works quite well within the confines of general systems theory, in situations in which a systems formulation inhibits rather than fosters explanation, a different interpretation of the term is warranted. This may be the case for disaster risk reduction, which involves transformation rather than preservation of the "state of the system". The article concludes that the modern conception of resilience derives benefit from a rich history of meanings and applications, but that it is dangerous - or at least potentially disappointing - to read to much into the term as a model and a paradigm.

Background Studies on popular names of birds help to understand the relationship between human beings and birds and it also contributes to the field of ornithology. Methods This study aims to register the ethnotaxonomy of birds in the village of Pedra Branca, Santa Teresinha municipality, Bahia State, Brazil, by cataloguing and identifying their popular names, besides understanding the ethnoclassification system of local bird species. The ethno-ornithological data were obtained by means of semi-structured open interviews, and projective tests. Results We interviewed 48 residents and, in order to identify species, we chose five informants with a more detailed knowledge on local avifauna. We registered 139 common names, distributed into 108 ethnospecies and 33 synonyms, referring to 117 species. Nomenclatural criteria more frequently used were vocalization and coloring patterns. Following Berlin’s principles of ethnobiological classification, three hierarchical levels were registered: life form, generic and specific, with three types of correspondence between Linnaean and folk classification systems. The bird life form (“pássaro” in Portuguese) was associated only to wild species. Conclusions The ethno-ornithological research in Pedra Branca Village has contributed with new information on popular nomenclature of birds and their etymology, showing that folk knowledge on birds is conveyed within the community.

The uses of traditional medicinal plants for primary health care have steadily increased worldwide in recent years. Scientists are in search of new phytochemicals that could be developed as useful anti-microbials for treatment of infectious diseases. Currently, out of 80% of pharmaceuticals derived from plants, very few are now being used as anti-microbials. Plants are rich in a wide variety of secondary metabolites that have found anti-microbial properties. This review highlights the current status of traditional medicine, its contribution to modern medicine, recent trends in the evaluation of anti-microbials with a special emphasis upon some tribal medicine, in vitro and in vivo experimental design for screening, and therapeutic efficacy in safety and human clinical trails for commercial outlet. Many of these commercially available compounds are crude preparations administered without performing human clinical trials. Recent methods are useful to standardize the extraction for scientific investigation of new phytochemicals and anti-microbials of traditionally used plants. It is concluded that once the local ethnomedical preparations of traditional sources are scientifically evaluated before dispensing they should replace existing drugs commonly used for the therapeutic treatment of infection. This method should be put into practice for future investigations in the field of ethnopharmacology, phytochemistry, ethnobotany and other biological fields for drug discovery. PMID:18955349

This study confirms the hypoglycemic effects of two extracts obtained from the Bromelia plumieri (BP) plant in streptozotocin-nicotinamide-induced diabetic rats (STZ-NA). BP has been traditionally used in the municipality of Tlanchinol Hidalgo, Mexico, to treat type 2 diabetes. Two different BP extracts were prepared and tested. The first extract was a water extract (WE), similar to that traditionally used to make tea, and the second extract was an ethanol:water extract (EWE). The extracts (WE at 35 and 350 mg/kg, and EWE at 30 and 300 mg/kg) were tested in STZ-NA-induced diabetic rats to determine whether hypoglycemia occurred after oral administration of the extracts. Phytochemistry: Two different extracts were prepared, n-hexane and butanol, to determine the presence of alkaloids, terpenes and flavonoids. The extracts that were administered to the STZ-NA-induced diabetic rats produced a significant hypoglycemic effect as compared with the control group, similar to that achieved with glibenclamide. We also determined that flavonoids were the main components of BP leaves. The results presented here support the hypothesis that extracts obtained from this plant have hypoglycemic effects, which are in agreement with the traditional uses of this plant. PMID:23576986

Beginning with solubilized membrane preparations, we have used chromatographic separations to identify a polypeptide with an apparent molecular mass of 29 kD, whose presence in various column fractions correlates with the acyltransferase activity detected in those same fractions. Amino acid sequence data obtained from several peptides generated from this protein were used to isolate a full-length clone from a coconut endosperm cDNA library. Clone pCGN5503 contains a 1325-bp cDNA insert with an open reading frame encoding a 308-amino acid protein with a calculated molecular mass of 34.8 kD. Comparison of the deduced amino acid sequence of pCGN5503 to sequences in the data banks revealed significant homology to other putative LPAAT sequences. Expression of the coconut cDNA in Escherichia coli conferred upon those cells a novel LPAAT activity whose substrate activity profile matched that of the coconut enzyme. PMID:8552723

Anti-diabetic properties and phytochemistry of Momordica charantia L. (Cucurbitaceae).

PubMed

Raman, A; Lau, C

1996-03-01

Unripe fruit, seeds and aerial parts of Momordica charantia Linn. (Cucurbitaceae) have been used in various parts of the world to treat diabetes. Oral administration of the fruit juice or seed powder causes a reduction in fasting blood glucose and improves glucose tolerance in normal and diabetic animals and in humans. Animal and in vitro data support both insulin secretagogue and insulinomimetic activity of the fruit. However, enhanced insulin levels in vivo in response to its administration have not been observed. Although a wide range of compounds have been isolated from Momordica charantia, notably steroidal compounds and proteins, the orally active antidiabetic principle has not been adequately identified. A polypeptide, p-insulin, produces hypoglycaemic effects in humans and animals on subcutaneous injection, but oral activity is questionable. Other reported hypoglycaemic principles from Momordica charantia include the sterol glucoside mixture charantin (fruit) and the pyrimidine nucleoside vicine (seeds). However these are only effective at doses too high to account for all the activity of the plant extract. Principal toxicity of Momordica charantia in animals is to the liver and reproductive system. These effects have not been reported in humans despite widespread use of the fruit medicinally and as a vegetable. Copyright © 1996 Gustav Fischer Verlag · Struttgart · Jena · New York.

Ethnopharmacology, phytochemistry, and biological activities of Cymbopogon citratus (DC.) Stapf extracts.

PubMed

Ekpenyong, Christopher E; Akpan, Ernest; Nyoh, Azah

2015-05-01

Cymbopogon citratus is a widely distributed perennial herb belonging to the Poaceae family and has been extensively consumed for its medicinal, cosmetic, and nutritional effects for centuries. A large number of reports have been published describing the pharmacological, biological, and therapeutic actions of this herb. In this review, we summarized the literatures on related studies (up to January, 2014) that highlighted the pharmacologic and biological effects of the major phytochemicals isolated from C. citratus extracts and its essential oil. The components of the essential oils found in C. citratus have a similar pharmacokinetic properties, including absorption, distribution, metabolism, and excretion. They are quickly absorbed following oral, pulmonary, and dermal administration. Based on the published reports, it can also be inferred that, after absorption from the small intestine, some phytochemicals in C. citratus can undergo oxidation, glucuronidation, sulfation, and/or O-methylation. Excretion is through urine, feces and/or expired volatiles. The biotransformation reactions of C. citratus bioactive constituents are essential for its relatively safe consumption and therapeutic applications. The data available so far warrant further studies evaluating C. citratus pharmacokinetics. Reliable pharmacokinetic data in humans would be critical for a better understanding of the the systemic handling of C. citratus. Copyright © 2015 China Pharmaceutical University.

The accumulation of CO2 and O3 in the troposphere alters phytochemistry which in turn influences the interactions between plants and insects. Using microarray analysis of field-grown soybean (Glycine max), we found that the number of transcripts in the leaves affected by herbivory by Japanese beetles (Popillia japonica) was greater when plants were grown under elevated CO2, elevated O3 and the combination of elevated CO2 plus elevated O3 than when grown in ambient atmosphere. The effect of herbivory on transcription diminished strongly with time (<1% of genes were affected by herbivory after 3 weeks), and elevated CO2 interacted more strongly with herbivory than elevated O3. The majority of transcripts affected by elevated O3 were related to antioxidant metabolism. Constitutive levels and the induction by herbivory of key transcripts associated with defence and hormone signalling were down-regulated under elevated CO2; 1-aminocyclopropane-1-carboxylate (ACC) synthase, lipoxygenase (LOX), allene oxide synthase (AOS), allene oxide cyclase (AOC), chalcone synthase (CHS), polyphenol oxidase (PPO) and cysteine protease inhibitor (CystPI) were lower in abundance compared with levels under ambient conditions. By suppressing the ability to mount an effective defence, elevated CO2 may decrease resistance of soybean to herbivory.

Lippia javanica (Burm.f.) Spreng.: Traditional and Commercial Uses and Phytochemical and Pharmacological Significance in the African and Indian Subcontinent

PubMed Central

2017-01-01

Lippia javanica occurs naturally in central, eastern, and southern Africa and has also been recorded in the tropical Indian subcontinent. The potential of L. javanica as herbal or recreational tea and herbal medicine and its associated phytochemistry and biological properties are reviewed. The extensive literature survey revealed that L. javanica is used as herbal tea and has ethnomedicinal applications such as in colds, cough, fever, malaria, wounds, diarrhoea, chest pains, bronchitis, and asthma. Multiple classes of phytochemicals including volatile and nonvolatile secondary metabolites such as alkaloids, amino acids, flavonoids, iridoids, and triterpenes as well as several minerals have been identified from L. javanica. Scientific studies on L. javanica indicate that it has a wide range of pharmacological activities which include anticancer, antiamoebic, antidiabetic, antimalarial, antimicrobial, antioxidant, antiplasmodial, and pesticidal effects. Although many of the traditional uses of L. javanica have been validated by phytochemical and pharmacological studies, there are still some gaps where current knowledge could be improved. Lippia javanica is popular as both herbal and recreational tea, but there is need for more precise studies to evaluate the safety and clinical value of its main active crude and pure compounds and to clarify their mechanisms of action.

Beta-sitosterol (BS) is a phytosterol, widely distributed throughout the plant kingdom and known to be involved in the stabilization of cell membranes. To compile the sources, physical and chemical properties, spectral and chromatographic analytical methods, synthesis, systemic effects, pharmacokinetics, therapeutic potentials, toxicity, drug delivery and finally, to suggest future research with BS, classical as well as on-line literature were studied. Classical literature includes classical books on ethnomedicine and phytochemistry, and the electronic search included Pubmed, SciFinder, Scopus, the Web of Science, Google Scholar, and others. BS could be obtained from different plants, but the total biosynthetic pathway, as well as its exact physiological and structural function in plants, have not been fully understood. Different pharmacological effects have been studied, but most of the mechanisms of action have not been studied in detail. Clinical trials with BS have shown beneficial effects in different diseases, but long-term study results are not available. These have contributed to its current status as an “orphan phytosterol”. Therefore, extensive research regarding its effect at cellular and molecular level in humans as well as addressing the claims made by commercial manufacturers such as the cholesterol lowering ability, immunological activity etc. are highly recommended.

The genus Fagopyrum (Polygonaceae), currently comprising 15 species of plants, includes three important buckwheat species: Fagopyrum esculentum (F. esculentum) Moench. (common buckwheat), Fagopyrum tataricum (F. tataricum) (L.) Gaertn. (tartary buckwheat) and Fagopyrum dibotrys (F. dibotrys) (D. Don) Hara. (perennial buckwheat), which have been well explored due to their long tradition of both edible and medicinal use. This review aimed to present an up-to-date and comprehensive analysis of the phytochemistry and pharmacology of the three Fagopyrum buckwheats. In addition, the scope for future research was also discussed. All available references included in this paper were compiled from major databases, such as MEDLINE, Pubmed, Scholar, Elsevier, Springer, Wiley and CNKI. A total of 106 compounds isolated from three Fagopyrum buckwheats can be mainly divided into six classes: flavonoids, phenolics, fagopyritols, triterpenoids, steroids and fatty acids. Flavonoids and phenolic compounds were considered to be the major active components. Considerable pharmacological experiments both in vitro and in vivo have validated that Fagopyrum buckwheats possess antitumor, anti-oxidant, anti-inflammatory, hepatoprotective, anti-diabetic activities, etc. All reported data lead us to conclude that Fagopyrum buckwheats have convincing medicinal potential. However, further research is needed to explore its bioactive constituents, the relationship to their structural activities and the molecular mechanisms of action. PMID:27104519

This study aims to examine the intensity of shade and proper dosage of fertilizer to maximize the content of ursolic acid and pearl grass yield. The field-run study was carried out at the Medicinal Plant Garden of the Research and Development of Medicinal Plants and Traditional Medicines (B2P2TOOT) and the laboratory research was conducted at the B2P2TOOT Phytochemistry Laboratory. The experiment design was Randomized Complete Block Design with Split Plot pattern with the intensity (three levels) as main plot and fertilizer dosage (four levels) as sub plot. The data obtained were analyzed using the variance analysis, if there were significant differences tested further by using Duncan’s Multiple Range Test (DMRT) with 95% confidence level. The results showed that shade treatment gave significant effects on plant height, number of branches, root length, fresh weight and dry weight. The treatment of a fertilizer dosage 15 tons/ha gave the best results on fresh weight and dry weight. The combination of N0K0 treatment (without shade, without cow manure) resulted in the highest quality of ursolic acid as it featured a light blue color when detected under UV366 light.

Ethnopharmacological Relevance. Dendrobii Officinalis Caulis, the stems of Dendrobium officinale Kimura et Migo, as a tonic herb in Chinese materia medica and health food in folk, has been utilized for the treatment of yin-deficiency diseases for decades. Methods. Information for analysis of Dendrobium officinale Kimura et Migo was obtained from libraries and Internet scientific databases such as PubMed, Web of Science, Google Scholar, ScienceDirect, Wiley InterScience, Ingenta, Embase, CNKI, and PubChem. Results. Over the past decades, about 190 compounds have been isolated from Dendrobium officinale Kimura et Migo. Its wide modern pharmacological actions in hepatoprotective effect, anticancer effect, hypoglycemic effect, antifatigue effect, gastric ulcer protective effect, and so on were reported. This may mainly attribute to the major and bioactive components: polysaccharides. However, other small molecule components require further study. Conclusions. Due to the lack of systematic data of Dendrobium officinale, it is important to explore its ingredient-function relationships with modern pharmacology. Recently, studies on the chemical constituents of Dendrobium officinale concentrated in crude polysaccharides and its structure-activity relationships remain scant. Further research is required to determine the Dendrobium officinale toxicological action and pharmacological mechanisms of other pure ingredients and crude extracts. In addition, investigation is needed for better quality control and novel drug or product development. PMID:28386292

2013-01-01

Background The marine environment is a unique source of bioactive natural products, of which Nizamuddinia zanardinii is an important brown algae distributed in Oman Sea. Literature revealed that there is no report on phytochemistry and pharmacology of this valuable algae. Methods Bioguided fractionation of the methanolic extract of Nizamuddinia zanardinii, collected from Oman Sea, led to the isolation of a hydroperoxy sterol. Its structure was determined by analysis of the spectroscopic data as 24-hydroperoxy-24-vinyl cholesterol (HVC). In vitro cytotoxic activity of this compound was evaluated against HT29, MCF7, A549, HepG2 and MDBK cell lines. Results Although 24(R)-hydroproxy-24-vinylcholesterol has been previously reported from Sargassum and Padina species, it is the first report on the presence of this compound from N. zanardinii. This compound exhibited cytotoxicity in all cell lines (IC50, 3.62, 9.09, 17.96, 32.31 and 37.31 μg/mL respectively). HVC was also evaluated for apoptotic activity and demonstrated positive results in terminal deoxynucleotidyl transferase dUTP Nick End labeling (TUNEL) assay suggesting it a candidate for further apoptotic studies. Conclusions Nizamuddinia zanardinii, a remarkable brown algae of Oman Sea, is a good source of hydroproxy sterols with promising cytotoxic on various cell lines particularly human colon adenocarcinoma.

A day in the life of a pharmacovigilance case processor.

PubMed

Bhangale, Ritesh; Vaity, Sayali; Kulkarni, Niranjan

2017-01-01

Pharmacovigilance (PV) has grown significantly in India in the last couple of decades. The etymological roots for the word "pharmacovigilance" are "Pharmakon" (Greek for drug) and "Vigilare" (Latin for to keep watch). It relies on information gathered from the collection of individual case safety reports and other pharmacoepidemiological data. The PV data processing cycle starts with data collection in computerized systems followed by complete data entry which includes adverse event coding, drug coding, causality and expectedness assessment, narrative writing, quality control, and report submissions followed by data storage and maintenance. A case processor plays an important role in conducting these various tasks. The case processor should also manage drug safety information, possess updated knowledge about global drug safety regulations, summarize clinical safety data, participate in meetings, write narratives with medical input from a physician, report serious adverse events to the regulatory authorities, participate in the training of operational staff on drug safety issues, quality control work of other staff in the department, and take on any other task as assigned by the manager or medical director within the capabilities of the drug safety associate. There can be challenges while handling all these tasks at a time, hence the associate will have to maintain a balance to overcome them and keep on updating their knowledge on drug safety regulations, which in turn, would help in increasing their learning curve.

Better infrastructure for critical care trials: nomenclature, etymology, and informatics.

PubMed

Singh, Jeffrey M; Ferguson, Niall D

2009-01-01

The goals of this review article are to review the importance and value of standardized definitions in clinical research, as well as to propose the necessary tools and infrastructure needed to advance nosology and medial taxonomy to improve the quality of clinical trials in the field of critical care. We searched MEDLINE for relevant articles, reviewed those selected and their reference lists, and consulted personal files for relevant information. When the pathobiology of diseases is well understood, standard disease definitions can be extremely specific and precise; however, when the pathobiology of the disease is less well understood or more complex, biological markers may not be diagnostically useful or even available. In these cases, syndromic definitions effectively classify and group illnesses with similar symptoms and clinical signs. There is no clear gold standard for the diagnosis of many clinical entities in the intensive care unit, including notably both acute respiratory distress syndrome and sepsis. There are several types of consensus methods that can be used to explicate the judgmental approach that is often needed in these cases, including interactive or consensus groups, the nominal group technique, and the Delphi technique. Ideally, the definition development process will create clear and unambiguous language in which each definition accurately reflects the current understanding of the disease state. The development, implementation, evaluation, revision, and reevaluation of standardized definitions are keys for advancing the quality of clinical trials in the critical care arena.

A psychrophilic yeast species was isolated from glacier cryoconite holes of Svalbard. Nucleotide sequences of the strains were studied using D1/D2 domain, ITS region and partial sequences of mitochondrial cytochrome b gene. The strains belonged to a clade of psychrophilic yeasts, but showed marked differences from related species in the D1/D2 domain and biochemical characters. Effects of temperature, salt and media on growth of the cultures were also studied. Screening of the cultures for amylase, cellulase, protease, lipase, urease and catalase activities was carried out. The strains expressed high amylase and lipase activities. Freeze tolerance ability of the isolates indicated the formation of unique hexagonal ice crystal structures due to presence of 'antifreeze proteins' (AFPs). FAME analysis of cultures showed a unique trend of increase in unsaturated fatty acids with decrease in temperature. The major fatty acids recorded were oleic acid, linoleic acid, linolenic acid, palmitic acid, stearic acid, myristic acid and pentadecanoic acid. Based on sequence data and, physiological and morphological properties of the strains, we propose a novel species, Rhodotorula svalbardensis and designate strains MLB-I (CCP-II) and CRY-YB-1 (CBS 12863, JCM 19699, JCM 19700, MTCC 10952) as its type strains (Etymology: sval.bar.den'sis.

Grips and ties: agency, uncertainty, and the problem of suffering in North Karelia.

PubMed

Honkasalo, Marja-Liisa

2009-03-01

In medical anthropological research, the question of suffering has been a topic of salient interest mostly from two theoretical viewpoints: those of endurance and of agency. The concept "suffering" derives its origins from two etymological roots, those of suffering-souffrance-sofferanza and of misery-misère-miseria. According to the first approach, that of "endurance" and founded largely on Judeo-Christian theology, suffering is regarded as an existential experience at the borders of human meaning making. The question then is: how to endure, how to suffer? The latter view, that of "agency," follows the Enlightenment, and later the Marxist view on mundane suffering, misery, and the modern question of how to avoid or diminish it. This article follows the lines of the second approach, but my aim is also to try to build a theoretical bridge between the two. I ask whether agency would be understood as a culturally shared and interpreted modes of enduring, and if so, which conceptual definition of agency applies in this context? I theorize the relationship between suffering and agency using Ernesto de Martino's notion la crisi della presenza. In line with Pierre Bourdieu, I think that in people's lives, there may be sufferings in a plural form, as a variety of sufferings. The article is based on a one-year long fieldwork in Finnish North Karelia.

The pulp of avocado (Persea americana, Lauraceae) has been reported to have beneficial cardiovascular health effects. Avocado oil is used for dermatological applications and its unsaponifiable portion is reported to have beneficial effects against osteoarthritis. Although the seed represents a considerable percentage of the total fruit, scientific research on the phytochemistry and biological effects of avocado seeds is in the nascent stages,. Currently, the seed represents an under-utilized resource and a waste issue for avocado processors. There is ethno-pharmacological information on the use of seeds for the treatment of health-related conditions, especially in South American countries where avocados are endemic and currently grown on a large scale. Current research has shown that avocado seeds may improve hypercholesterolemia, and be useful in the treatment of hypertension, inflammatory conditions and diabetes. Seeds have also been found to possess insecticidal, fungicidal, and anti-microbial activities. The avocado seeds and rich in phenolic compounds, and these may play a role in the putative health effects. Historically, extracts of avocado seeds were also used as ink for writing and research in our laboratory has explored the potential colorant properties of a polyphenol oxidase-produced colored avocado seed extract. Here, we review the currently-available data on the bioactivity and other functional properties of avocado seeds. We discuss the strength of the available data, the putative active compounds, and potential directions for future studies.

Hibiscus sabdariffa L. (roselle) belonging to the Malvaceae family is widely grown in many countries. This plant is often used in the traditional medicine being rich in phytochemicals like polyphenols especially anthocyanins, polysaccharides and organic acids thus having enormous prospective in modern therapeutic uses. The study aimed to review and document all the available evidence and information about the calyces of Hibiscus sabdariffa (roselle) with the special focus on their nutritional composition, bioactive constituents and therapeutic uses. The electronic database was searched up to 2017, using keywords Hibiscus sabdariffa, chemical constituents of roselle, therapeutic uses of roselle. Journals, books and conference proceedings were also searched. The review provides valuable information about the nutraceutical component of Hibiscus sabdariffa L. and their utilization for curing various degenerative diseases like hypertension, hyperlipidemia, cancer and other inflammatory diseases of liver and kidney. Their toxicological effects have also been discussed from a safety point of view. Most studies supported and provided the scientific basis for the statement that Hibiscus sabdariffa and their active constituents play an important role in the prevention of chronic and degenerative diseases that are associated with oxidative stress. Our study suggests, that good research is needed, to establish a potential strategy that can balance the pharmacological and toxic effects of roselle and standardized fingerprint of Hibiscus sabdariffa is required internationally for quality control.

From the perspective of an herbivorous insect, conspecific host plants are not identical, and intraspecific variation in host nutritional quality or defensive capacity might mediate spatially variable outcomes in plant-insect interactions. Here we explore this possibility in the context of an ongoing host breadth expansion of a native butterfly (the Melissa blue, Lycaeides melissa) onto an exotic host plant (alfalfa, Medicago sativa). We examine variation among seven alfalfa populations that differed in terms of colonization by L. melissa; specifically, we examined variation in phytochemistry, foliar protein, and plant population genetic structure, as well as responses of caterpillars and adult butterflies to foliage from the same populations. Regional patterns of alfalfa colonization by L. melissa were well predicted by phytochemical variation, and colonized patches of alfalfa showed a similar level of inter-individual phytochemical diversity. However, phytochemical variation was a poor predictor of larval performance, despite the fact that survival and weight gain differed dramatically among caterpillars reared on plants from different alfalfa populations. Moreover, we observed a mismatch between alfalfa supporting the best larval performance and alfalfa favored by ovipositing females. Thus, the axes of plant variation that mediate interactions with L. melissa depend upon herbivore life history stage, which raises important issues for our understanding of adaptation to novel resources by an organism with a complex life history.

The aim of the study was to evaluate the phytochemistry and the effect of methanolic root extract (MREt) of Rauwolfia serpentina on alloxan-induced diabetic Wister male mice. Mice were divided in control (distilled water at 1 mL/kg) and alloxan-induced diabetic mice which subdivided into diabetic (distilled water at 1 mL/kg), negative (0.05% dimethyl sulfoxide at 1 mL/kg), positive (glibenclamide at 5 mg/kg) controls, and three test groups (MREt at 10, 30, and 60 mg/kg). All treatments were given orally for 14 days. Qualitatively MREt showed the presence of alkaloids, carbohydrates, flavonoids, glycosides, cardiac glycosides, phlobatannins, resins, saponins, steroids, tannins, and triterpenoids, while quantitatively extract was rich in total phenols. The flavonoids, saponins and alkaloids were also determined in root powder. MREt found effective in improving the body weights, glucose and insulin levels, insulin/glucose ratio, glycosylated and total hemoglobin in test groups as compared to diabetic control. Similarly, significantly decreased levels of total cholesterol, triglycerides, low-density lipoprotein (LDL-c), and very low-density lipoprotein (VLDL-c) cholesterols were found in test groups. Significant lipolysis with improved glycogenesis was also found in liver tissues of all test groups. ALT levels were found normal in all groups. Thus, MREt improves the glycemic, antiatherogenic, coronary risk, and cardioprotective indices in alloxan-induced diabetic mice.

The aim of the present review is to comprehensively outline the botanical description, traditional uses, phytochemistry, pharmacology and toxicology of Patrinia, and to discuss possible trends for the further study of medicinal plants from the genus Patrinia. The genus Patrinia plays an important role in Asian medicine for the treatment of erysipelas, conjunctival congestion with swelling and pain, peri-appendicular abscesses, lung carbuncle, dysentery, leucorrhea, and postpartum disease. More than 210 chemical constituents have been isolated and identified from Patrinia plants, especially P. scabiosaefolia Fisch., P. scabra Bunge, P. villosa Juss., P. heterophylla Bunge and P. rupestris(Pall.) Juss[Formula: see text] Of these compounds, triterpenoids and saponins, iridoids, flavonoids, and lignans are the major or active constituents. Both in vitro and in vivo studies have indicated that some monomer compounds and crude extracts from the genus Patrinia possess wide pharmacological activities, including antitumor, anti-inflammatory, antibacterial, and antiviral effects. In addition, they have been shown to have valuable and positive effects on the immune and nervous system in experimental animals. There are also some reports on the clinical uses and toxicity of these species. However, few reports have been published concerning the material identification or quality control of Patrinia species, and the clinical uses and toxic effects of these plants are relatively sparse. More attention must be given to these issues.

2014-07-03

In particular five polypore species, i.e. Laetiporus sulphureus, Fomes fomentarius, Fomitopsis pinicola, Piptoporus betulinus, and Laricifomes officinalis, have been widely used in central European folk medicines for the treatment of various diseases, e.g. dysmenorrhoea, haemorrhoids, bladder disorders, pyretic diseases, treatment of coughs, cancer, and rheumatism. Prehistoric artefacts going back to over 5000 years underline the long tradition of using polypores for various applications ranging from food or tinder material to medicinal-spiritual uses as witnessed by two polypore species found among items of Ötzi, the Iceman. The present paper reviews the traditional uses, phytochemistry, and biological activity of the five mentioned polypores. All available information on the selected polypore taxa used in traditional folk medicine was collected through evaluation of literature in libraries and searches in online databases using SciFinder and Web of Knowledge. Mycochemical studies report the presence of many primary (e.g. polysaccharides) and secondary metabolites (e.g. triterpenes). Crude extracts and isolated compounds show a wide spectrum of biological properties, such as anti-inflammatory, cytotoxic, and antimicrobial activities. The investigated polypores possess a longstanding ethnomycological tradition in Europe. Here, we compile biological results which highlight their therapeutic value. Moreover, this work provides a solid base for further investigations on a molecular level, both compound- and target-wise. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Abhava pratinidhi dravya: A comparative phytochemistry of Ativisha, Musta and related species

Nagarajan, M.; Kuruvilla, Gina R.; Kumar, K. Subrahmanya; Venkatasubramanian, Padma

2015-01-01

Authentic Ativisha (Aconitum heterophyllum) is a rare, endangered Himalayan species. Ayurveda classical texts of c. 15th–16th century, introduced “abhava-pratinidhi dravya” concept, wherein Ativisha was categorized as an abhava dravya (unavailable drug) and Musta (Cyperus rotundus) was suggested as a pratinidhi dravya (substitute) for it. C. rotundus is a weed, abundantly available pan-India. Cryptocoryne spiralis (Naattu Athividayam) and Cyperus scariosus (Nagarmotha) are also traded as Ativisha and Musta, respectively. Yet, there are no scientific studies to validate the use of substitutes. A. heterophyllum bears no similarity in terms of botanical classification with the other candidates. This article reviews published literature with an emphasis to look for similar phytochemicals or groups of phytochemicals in the species that could contribute to similar pharmacological activities, thereby supporting the drug substitution from a bio-medical perspective. Alkaloids like atisine were found to be the main focus of studies on A. heterophyllum, whereas for the Cyperus spp., it was terpenoids like cyperene. Although alkaloids and terpenoids were reported from both species, alkaloids in C. rotundus and terpenoids in A. heterophyllum were minor constituents. Reports on phytochemicals on Cryptocoryne spiralis and C. scariosus were very limited. Despite no significant similarities in chemical profiles reported, the dravyaguna (Ayurvedic drug classification) of Ativisha and Musta was quite similar warranting further exploration into the bio-functional aspects of the drug materials.

Gitksan medicinal plants-cultural choice and efficacy

PubMed Central

Johnson, Leslie Main

2006-01-01

Background The use of plants for healing by any cultural group is integrally related to local concepts of the nature of disease, the nature of plants, and the world view of the culture. The physical and chemical properties of the plants themselves also bear on their selection by people for medicines, as does the array of plants available for people to choose from. I examine use of medicinal plants from a "biobehavioral" perspective to illuminate cultural selection of plants used for medicine by the Gitksan of northwestern British Columbia, Canada. Methods Consultant consensus, "intercultural consensus", independent use of the same plants by other cultural groups, and phytochemistry and bioassay results from the literature, were employed in analysis of probable empirical efficacy of plant uses. Results 70% of 37 Gitksan medicinal plants were used similarly by other cultures where direct diffusion is not known to have occurred; eleven plants, including the eight most frequently mentioned medicinal plants, also show active phytochemicals or bioassays indicating probable physiologically based therapeutic effects. Conclusion Analysis of intercultural consensus revealed that the majority of cultures in the British Columbia region within the plant ranges use the same plants, or closely related species, in similar ways. The rigor of this analysis is effected by the lack of consistent data on all taxa of interest for all cultures within the region. PMID:16790066

Objective: There are a number of published data indicating in vitro anti-HSV activity of some of Iranian herbal extracts with no systematic review to discuss these results. Therefore, this article was aimed to review and discuss the methods carried out and the phytochemistry and bioactivity of the extracts used and also conclusions provided in these publications. Materials and Methods: Published articles both in English (from Medline, Science Direct, EMBASE, Scopus, Pro Quest, Google scholar, Cochrane Library) and in Persian (from SID, Iran Medex and Magiran) databases, from 1966 to October 2014 were incorporated in this review. The in vitro studies that lacked CC50, IC50, were excluded. Results: Only 42 published reports were found to examine Iranian herbs against HSV replication in vitro. Seventeen out of 42 studies in which 23 kinds of medicinal plants were subjected to crude extraction were included. The review of data showed that some of the herbal extracts including Hyssopus officinalis methanolic extract, Melissa officinalis aqueous extract, Quercus persica L. hydroalcoholic extract and Securigeras ecuridaca methanolic extract with selective index (SI) of 234, 877, >778 and 250, respectively were highly effective against HSV in vitro. Conclusion: More comprehensive studies using more advanced methods are needed to be done to achieve promising anti-HSV agents from the bioactive compounds isolated from these herbs. PMID:27761420

Date fruit, Phoenix dactylifera L. has traditionally been used as a medicine in many cultures for the treatment of a range of ailments such as stomach and intestinal disorders, fever, oedema, bronchitis and wound healing. The present review aims to summarise the traditional use and application of P. dactylifera date fruit in different ethnomedical systems, additionally the botany and phytochemistry are identified. Critical evaluation of in vitro and in vitro studies examining date fruit in relation to anti-inflammatory, anti-angiogenic and antimicrobial activities are outlined. The ethnomedical use of P. dactylifera in the treatment of inflammatory disease has been previously identified and reported. Furthermore, date fruit and date fruit co-products such as date syrup are rich sources of polyphenols, anthocyanins, sterols and carotenoids. In vitro studies have demonstrated that date fruit exhibits antibacterial, anti-inflammatory and anti-angiogenic activity. The recent interest in the identification of the numerous health benefits of dates using in vitro and in vivo studies have confirmed that date fruit and date syrup have beneficial health effects that can be attributed to the presence of natural bioactive compounds. Date fruit and date syrup have therapeutic properties, which have the potential to be beneficial to health. However, more investigations are needed to quantify and validate these effects.

Anatomical, histochemical and phytochemistry methods were used to investigate the structure of vegetative organs, and saponins localization and dynamic changes in Polygala sibirica L. The root consisted of developed periderm and secondary vascular. The secondary phloem was thick, and mainly composed of parenchyma. There were well-developed vessels and fibers in the secondary xylem. The stem was composed of epidermis, cortex and vascular bundle. The ring of sclerenchymatous cells lied between cortex and phloem might be the apoplastic protective screen which could protect the stem from drought. The leaf was bifacial one. The root and stem possessed characteristics adapting to arid environment. Histochemical localization results showed that saponins distributed in secondary phloem and phelloderm of root, in epidermis, cortex and phloem of stem, mainly in mesophyll of leaf. It displayed that saponins accumulated mainly in parenchyma cells of vegetative organs, among of which, the secondary phloem was the main storage site. The HPLC results also showed that the saponins accumulated in all the vegetative organs of Polygala sibirica L., with higher content in roots and lower content in the aerial part that included stems and leaves. The study indicated the aerial part of Polygala sibirica L. also had medicinal value. The saponins content had dynamic variance at the developmental stage, the crude drug should be gathered at period from April to May.

Lichens are symbiotic associations of fungi with microalgae and/or cyanobacteria, which are considered among the slowest growing organisms, with strong tolerance to adverse environmental conditions. There are about 400 genera and 1600 species of lichens and those belonging to the Usnea genus comprise about 360 of these species. Usnea lichens have been used since ancient times as dyes, cosmetics, preservatives, deodorants and folk medicines. The phytochemistry of the Usnea genus includes more than 60 compounds which belong to the following classes: depsides, depsidones, depsones, lactones, quinones, phenolics, polysaccharides, fatty acids and dibenzofurans. Due to scarce knowledge of metabolomic profiles of Usnea species ( U. barbata , U. antarctica , U. rubicunda and U. subfloridana ), a study based on UHPLC-ESI-OT-MS-MS was performed for a comprehensive characterization of their secondary metabolites. From the methanolic extracts of these species a total of 73 metabolites were identified for the first time using this hyphenated technique, including 34 compounds in U. barbata , 21 in U. antarctica , 38 in U. rubicunda and 37 in U. subfloridana . Besides, a total of 13 metabolites were not identified and reported so far, and could be new according to our data analysis. This study showed that this hyphenated technique is rapid, effective and accurate for phytochemical identification of lichen metabolites and the data collected could be useful for chemotaxonomic studies.

Phytochemical diversity drives plant–insect community diversity

What are the ecological causes and consequences of variation in phytochemical diversity within and between plant taxa? Despite decades of natural products discovery by organic chemists and research by chemical ecologists, our understanding of phytochemically mediated ecological processes in natural communities has been restricted to studies of either broad classes of compounds or a small number of well-characterized molecules. Until now, no studies have assessed the ecological causes or consequences of rigorously quantified phytochemical diversity across taxa in natural systems. Consequently, hypotheses that attempt to explain variation in phytochemical diversity among plants remain largely untested. We use spectral data from crude plant extracts to characterize phytochemical diversity in a suite of co-occurring plants in the tropical genus Piper (Piperaceae). In combination with 20 years of data focused on Piper-associated insects, we find that phytochemical diversity has a direct and positive effect on the diversity of herbivores but also reduces overall herbivore damage. Elevated chemical diversity is associated with more specialized assemblages of herbivores, and the cascading positive effect of phytochemistry on herbivore enemies is stronger as herbivore diet breadth narrows. These results are consistent with traditional hypotheses that predict positive associations between plant chemical diversity, insect herbivore diversity, and trophic specialization. It is clear from these results that high phytochemical diversity not only enhances the diversity of plant-associated insects but also contributes to the ecological predominance of specialized insect herbivores.

Beta vulgaris (family: Chenopodiacea) is now much used in the food industry as a rich source of sugar but it is much less considered in medicine. Beet has been used in traditional medicine for hundreds of years to treat a variety of diseases such as constipation, decreased libido, gut and joint pain and dandruff. This study introduced the benefits of Beta vulgaris by reviewing of Iranian traditional documents from 10th century until now and also compared modern phytotherapy of plant beet from the electronic data banks such as ISI, Pub Med and Scopus with findings that extracted from traditional literature. This plant is known in Iranian traditional medicine (ITM) as Selgh (Arabic) or Choghondar (Farsi) and its leaves are used to develop treatments. Results confirmed that the plant referred to as Selgh in traditional books is that the plant Beta vulgaris in contemporary studies. Treatments that have not been evaluated in modern phytotherapy but do appear in traditional treatments include fever, as well as psychological and psychiatric issues. This article tells the history of beet in ITM and can confirm use of plant Beta vulgaris in medicinal practice. The report can be applied for certification of plant Beta vulgaris for researchers and experts. The findings of this study can help the researchers in producing therapeutic products and new application.

The chloroform extract of the stem bark of Amburana cearensis was chemically characterized and tested for antibacterial activity.The extract was analyzed by gas chromatography and mass spectrometry. The main compounds identified were 4-methoxy-3-methylphenol (76.7%), triciclene (3.9%), α-pinene (1.0%), β-pinene (2.2%), and 4-hydroxybenzoic acid (3.1%). Preliminary antibacterial tests were carried out against species of distinct morphophysiological characteristics: Escherichia coli, Salmonella enterica Serotype Typhimurium, Pseudomonas aeruginosa, Staphylococcus aureus, Listeria monocytogenes, and Bacillus cereus. The minimum inhibitory concentration (MIC) was determinate in 96-well microplates for the chloroform extract and an analogue of themain compound identified, which was purchased commercially.We have shown that plant's extract was only inhibitory (but not bactericidal) at the maximum concentration of 6900 μg/mL against Pseudomonas aeruginosa and Bacillus cereus. Conversely, the analogue 2-methoxy-4-methylphenol produced MICs ranging from215 to 431 μg/mL against all bacterial species.New antibacterial assays conducted with such chemical compound against Klebsiella pneumoniae carbapenemase-producing strains have shown similarMICresults and minimumbactericidal concentration (MBC) of 431 μg/mL.We conclude that A. cearensis is a good source of methoxy-methylphenol compounds,which could be screened for antibacterial activity againstmultiresistant bacteria fromdifferent species PMID:24772183

Crataegus oxyacantha L. (syn. C. rhipidophylla Gand.) (Rosaceae) is one of two medicinally recognized hawthorn species in European Pharmacopeia. Standardization of the extract prepared from the berry and flowers of the plant is required according to its oligomeric procyanidins. C. oxyacantha is well-known for its use in the treatment of various heart problems particularly, including heart failure in cases of declining cardiac performance equivalent to stages I and II of the New York Heart Association classification, angina pectoris, hypertension with myocardial insufficiency, mild alterations of cardiac rhythm, and atherosclerosis. C. oxyacantha has been reported to exert several other pharmacological activities such as hypotensive, antihyperlipidemic, antihyperglycemic, anxiolytic, immunomodulatory, and antimutagenic. Oligomeric procyanidins and flavone/flavonol types of flavonoids, which are considered to be the chief groups of active substances, phenolic acids, triterpenes, fatty acids, and sterols are present in the plant. The present review aims mainly to outline cardiotonic effect of C. oxyacantha as well as its brief phytochemistry. Numerous experiments and clinical studies have underlined cardiovascular efficacy of the plant through various mechanisms including positive inotropic and negative chronotropic effects, escalation in coronary blood flow and exercise tolerance, inhibition of the enzymes such as angiotensin-converting enzyme (ACE) and phosphodiesterase, anti-inflammatory and antihyperlipidemic effects, improving status of antioxidant enzymes, etc., which support its cardioactive efficacy. The plant possesses several other bioactivities for human health usually concomitant to its rich polyphenolic content.

The Panax genus is a crucial source of natural medicines that has benefited human health for a long time. Three valuable medicinal herbs, namely Panax ginseng, Panax quinquefolius, and Panax notoginseng, have received considerable interest due to their extensive application in clinical therapy, healthcare products, and as foods and food additives world-wide. Panax species are known to contain abundant levels of saponins, also dubbed ginsenosides, which refer to a series of dammarane or oleanane type triterpenoid glycosides. These saponins exhibit modulatory effects to the central nervous system and beneficial effects to patients suffering from cardiovascular diseases, and also have anti-diabetic and anti-tumor properties. To the end of 2012, at least 289 saponins were reported from eleven different Panax species. This comprehensive review describes the advances in the phytochemistry of the genus Panax for the period 1963-2012, based on the 134 cited references. The reported saponins can be classified into protopanaxadiol, protopanaxatriol, octillol, oleanolic acid, C17 side-chain varied, and miscellaneous subtypes, according to structural differences in sapogenins. The investigational history of Panax is also reviewed, with special attention being paid to the structural features of the six different subtypes, together with their (1)H and (13)C NMR spectroscopic characteristics which are useful for determining their structures and absolute configuration.

The use of chemical defensives to control fungal diseases has by consequence to impact negatively over the environment and human health, this way, the use of plant extracts with antifungal properties along with proper cultural management makes viable an alternative plant production control, specially for familiar and organic cultures. The objective of this study was to perform phytochemical and antioxidant analysis of Byrsonima crassifolia (canjiqueira) barks and evaluate its antifungal potential over Fusarium solani and Sclerotinia sclerotiorum mycelial growth. The ethanol extract from plants collected in Pantanal, Mato Grosso do Sul, Brazil was submitted to phytochemical prospection, total phenol and flavonoids quantification and antioxidant activiy determination (DPPH). To evaluate antifungal activity concentrations of 800, 1200, 1600, 2000 and 2400 µg 100 mL-1 of ethanol extract were used. Which concentration was separately incorporated in agar (PDA) and shed in Petri dishes, followed by the fungi mycelial disc where the colonies diameter was measured daily. Negatives control with agar without extract and agar with an ethanol solution were used. The B. crassifolia ethanol extract presented inhibitory activity over the fungi studied where concentrations of 800 and 1600 µg 100 mL-1, inhibited 38% of the mycelial growth of F. solani; to S. sclerotiorum the best concentration was 2400 µg 100 mL1, reducing 37.5%. The antifungal bark extract potential of this specie is attributed to phenolic compounds and to triterpenes derivatives.

Planetary Taxonomy: Label Round Bodies "Worlds"

NASA Astrophysics Data System (ADS)

Margot, Jean-Luc; Levison, H. F.

2009-05-01

The classification of planetary bodies is as important to Astronomy as taxonomy is to other sciences. The etymological, historical, and IAU definitions of planet rely on a dynamical criterion, but some authors prefer a geophysical criterion based on "roundness". Although the former criterion is superior when it comes to classifying newly discovered objects, the conflict need not exist if we agree to identify the subset of "round" planetary objects as "worlds". This addition to the taxonomy would conveniently recognize that "round" objects such as Earth, Europa, Titan, Triton, and Pluto share some common planetary-type processes regardless of their distance from the host star. Some of these worlds are planets, others are not. Defining how round is round and handling the inevitable transition objects are non-trivial tasks. Because images at sufficient resolution are not available for the overwhelming majority of newly discovered objects, the degree of roundness is not a directly observable property and is inherently problematic as a basis for classification. We can tolerate some uncertainty in establishing the "world" status of a newly discovered object, and still establish its planet or satellite status with existing dynamical criteria. Because orbital parameters are directly observable, and because mass can often be measured either from orbital perturbations or from the presence of companions, the dynamics provide a robust and practical planet classification scheme. It may also be possible to determine which bodies are dynamically dominant from observations of the population magnitude/size distribution.

The environmental geochemistry of Arsenic – An overview

USGS Publications Warehouse

Bowell, Robert J.; Alpers, Charles N.; Jamieson, Heather E.; Nordstrom, D. Kirk; Majzlan, Juraj

2014-01-01

Arsenic is one of the most prevalent toxic elements in the environment. The toxicity, mobility, and fate of arsenic in the environment are determined by a complex series of controls dependent on mineralogy, chemical speciation, and biological processes. The element was first described by Theophrastus in 300 B.C. and named arsenikon (also arrhenicon; Caley and Richards 1956) referring to its “potent” nature, although it was originally considered an alternative form of sulfur (Boyle and Jonasson 1973). Arsenikon is believed to be derived from the earlier Persian, zarnik (online etymology dictionary, http://www.etymonline.com/index.php?term=arsenic). It was not until the thirteenth century that an alchemist, Albertus Magnus, was able to isolate the element from orpiment, an arsenic sulfide (As2S3). The complex chemistry required to do this led to arsenic being considered a “bastard metal” or what we now call a “metalloid,” having properties of both metals and non-metals. As a chemical element, arsenic is widely distributed in nature and can be concentrated in many different ways. In the Earth’s crust, arsenic is concentrated by magmatic and hydrothermal processes and has been used as a “pathfinder” for metallic ore deposits, particularly gold, tin, copper, and tungsten (Boyle and Jonasson 1973; Cohen and Bowell 2014). It has for centuries been considered a potent toxin, is a common poison in actual and fictional crimes, and has led to significant impacts on human health in many areas of the world (Cullen 2008; Wharton 2010).

Cretaceous shelf-sea chalk deposits

The word ''chalk'' is linked etymologically to the Cretaceous, but chalky facies neither dominate that system nor are confined to it. As used commonly, the term ''chalk'' refers to a variety of marine limestone that is white to light gray very fine grained, soft and friable, porous, and composed predominantly of calcitic skeletal remains, especially those derived from coccolithophores. No simple definition suffices to embrace all Cretaceous chalks, which include sandy, marly, shelly, phospatic, glauconitic, dolomitic, pyritic and organic-rich lithotypes. Most of the world's exposed Cretaceous chalk deposits were formed at shelf depths rather than in the deep sea. Cretaceousmore » shelf-sea chalks are developed most extensively in northern Europe, the U.S. Gulf Coastal Plain and Western Interior, and the Middle East, with lesser occurrences alo in Australia. Most Cretaceous shelf-sea chalks formed in the temperature zones, and in relatively deep water. Cretaceous chalks deposited on well-oxygenated sea floors are bioturbated and massive where deficient in terrigenous detritus, or bioturbated and rhythmically interbedded with argillaceous units where influx of terrigenous detritus varied systematically with climate changes. Accumulation of sufficient pelagic mud to form vast deposits of Cretaceous shelf-sea chalk required (1) sustained high productivity of calareous plankton, (2) extensive development of stable shelf and continental platform environments, (3) highstands of seal level, (4) deficiency of aragonitic skeletal material in chalk-forming sediments, and (5) low rates of terrigenous detrital influx. These conditions were met at different times in different places, even within the same general region.« less

What is the link between synaesthesia and sound symbolism?

PubMed Central

Bankieris, Kaitlyn; Simner, Julia

2015-01-01

Sound symbolism is a property of certain words which have a direct link between their phonological form and their semantic meaning. In certain instances, sound symbolism can allow non-native speakers to understand the meanings of etymologically unfamiliar foreign words, although the mechanisms driving this are not well understood. We examined whether sound symbolism might be mediated by the same types of cross-modal processes that typify synaesthetic experiences. Synaesthesia is an inherited condition in which sensory or cognitive stimuli (e.g., sounds, words) cause additional, unusual cross-modal percepts (e.g., sounds trigger colours, words trigger tastes). Synaesthesia may be an exaggeration of normal cross-modal processing, and if so, there may be a link between synaesthesia and the type of cross-modality inherent in sound symbolism. To test this we predicted that synaesthetes would have superior understanding of unfamiliar (sound symbolic) foreign words. In our study, 19 grapheme-colour synaesthetes and 57 non-synaesthete controls were presented with 400 adjectives from 10 unfamiliar languages and were asked to guess the meaning of each word in a two-alternative forced-choice task. Both groups showed superior understanding compared to chance levels, but synaesthetes significantly outperformed controls. This heightened ability suggests that sound symbolism may rely on the types of cross-modal integration that drive synaesthetes’ unusual experiences. It also suggests that synaesthesia endows or co-occurs with heightened multi-modal skills, and that this can arise in domains unrelated to the specific form of synaesthesia. PMID:25498744

Tracing the Origins of Success: Implications for Successful Aging

PubMed Central

Peterson, Nora M.; Martin, Peter

2015-01-01

Purpose of the Study: This paper addresses the debate about the use of the term “successful aging” from a humanistic, rather than behavioral, perspective. It attempts to uncover what success, a term frequently associated with aging, is: how can it be defined and when did it first come into use? In this paper, we draw from a number of humanistic perspectives, including the historical and linguistic, in order to explore the evolution of the term “success.” We believe that words and concepts have deep implications for how concepts (such as aging) are culturally and historically perceived. Design and Methods: We take a comparative approach, turning to the etymological roots of this term in British, French, and German literature. According to the earliest entries of the term in the Oxford English Dictionary, events can have good or bad success. Another definition marks success as outcome oriented. Results: Often used in the context of war, religion, and medicine, the neutral, but often negative, use of “success” in literature of the Renaissance demonstrates the tensions that surround the word, and suggests that success is something to be approached carefully. Implications: Ignoring the ambiguous origins of success erases the fact that aging in earlier centuries echoes much of the same ambivalence with which many people discuss it today. Attending to the origins of success can help gerontologists understand the humanistic tradition behind their inquiry into what successful aging means today. PMID:24997595

Resilience and disaster risk reduction: an etymological journey

NASA Astrophysics Data System (ADS)

Alexander, D. E.

2013-04-01

This paper examines the development over historical time of the meaning and uses of the term resilience. The objective is to deepen our understanding of how the term came to be adopted in disaster risk reduction and resolve some of the conflicts and controversies that have arisen when it has been used. The paper traces the development of resilience through the sciences, humanities, and legal and political spheres. It considers how mechanics passed the word to ecology and psychology, and how from there it was adopted by social research and sustainability science. As other authors have noted, as a concept, resilience involves some potentially serious conflicts or contradictions, for example between stability and dynamism, or between dynamic equilibrium (homeostasis) and evolution. Moreover, although the resilience concept works quite well within the confines of General Systems Theory, in situations in which a systems formulation inhibits rather than fosters explanation, a different interpretation of the term is warranted. This may be the case for disaster risk reduction, which involves transformation rather than preservation of the ''state of the system''. The article concludes that the modern conception of resilience derives benefit from a rich history of meanings and applications, but that it is dangerous - or at least potentially disappointing - to read to much into the term as a model and a paradigm.

Medication errors: definitions and classification

PubMed Central

Aronson, Jeffrey K

2009-01-01

To understand medication errors and to identify preventive strategies, we need to classify them and define the terms that describe them. The four main approaches to defining technical terms consider etymology, usage, previous definitions, and the Ramsey–Lewis method (based on an understanding of theory and practice). A medication error is ‘a failure in the treatment process that leads to, or has the potential to lead to, harm to the patient’. Prescribing faults, a subset of medication errors, should be distinguished from prescription errors. A prescribing fault is ‘a failure in the prescribing [decision-making] process that leads to, or has the potential to lead to, harm to the patient’. The converse of this, ‘balanced prescribing’ is ‘the use of a medicine that is appropriate to the patient's condition and, within the limits created by the uncertainty that attends therapeutic decisions, in a dosage regimen that optimizes the balance of benefit to harm’. This excludes all forms of prescribing faults, such as irrational, inappropriate, and ineffective prescribing, underprescribing and overprescribing. A prescription error is ‘a failure in the prescription writing process that results in a wrong instruction about one or more of the normal features of a prescription’. The ‘normal features’ include the identity of the recipient, the identity of the drug, the formulation, dose, route, timing, frequency, and duration of administration. Medication errors can be classified, invoking psychological theory, as knowledge-based mistakes, rule-based mistakes, action-based slips, and memory-based lapses. This classification informs preventive strategies. PMID:19594526

Ethnobotanical survey, chemical composition, and antioxidant capacity of methanolic extract of the root bark of Annona cuneata Oliv.

2011-11-01

The root bark of Annona cuneata Oliv. is traditionally used in the Democratic Republic of Congo to treat several debilitating conditions, such as hernia, female sterility, sexual asthenia, and parasitic infections. However, little is known about the composition of the secondary plant substances, which may contribute to these traditional medicinal effects. We conducted an ethnobotanical study and then evaluated the composition of the secondary plant substances in extracts of the root bark by using spectroscopic methods. After delipidation, the root bark was lixiviated in methanol, and components in the extract were studied by gas chromatography-mass spectometry, high-performance liquid chromatography (HPLC)-electrospray ionization-MS and nano-electrospray ionization-MS-MS. These methods identified 13 secondary plant substances (almost exclusively phenolic compounds): p-hydroxybenzaldehyde (I), vanillin (II), tyrosol (III), 3,4-dihydroxybenzaldehyde (IV), p-hydroxybenzoic acid (V), vanillyl alcohol (VI), syringaldehyde (VII), 4-hydroxy-3-methoxyphenylethanol (VIII), vanillic acid (IX), 3,4-dihydroxybenzoic acid (X), syringic acid (XI), and ferulic acid (XII), along with the phytosterol squalene (XIII). In the HPLC-based hypoxanthine/xanthine oxidase antioxidant assay system, the methanolic extract exhibited potent antioxidant capacity, with a 50% inhibitory concentration of 72 μL, equivalent to 1.38 mg/mL of raw extract. Thus, a methanol extract of A. cuneata Oliv. contained a range of polyphenolic compounds, which may be partly responsible for its known traditional medicinal effects. More detailed studies on the phytochemistry of this important plant species are therefore warranted.

The Cree of Eeyou Istchee in Northern Quebec identified Sarracenia purpurea L. as an important plant for the treatment of Type 2 diabetes. Traditionally the plant is used as a decoction (boiling water extract) of the leaf, however, in order to study the extract in a laboratory setting, an 80% ethanol extract was used. In this study, the phytochemistry of both extracts of the leaves was compared and quantified. Two S. purpurea leaf extracts were prepared, one a traditional hot water extract and the other an 80% ethanol extract. Using UPLC-ESI-MS, the extracts were phytochemically compared for 2 triterpenes, betulinic acid and ursolic acid, using one gradient method and for 10 additional substances, including the actives quercetin-3-O-galactoside and morroniside, using a different method. The concentrations of the nine phenolic substances present, as well as an active principle, the iridoid glycoside morroniside, were very similar between the two extracts, with generally slightly higher concentrations of phenolics in the ethanol extract as expected. However, two triterpenes, betulinic acid and ursolic acid, were 107 and 93 times more concentrated, respectively, in the ethanol extract compared to the water extract. The main phytochemical markers and most importantly the antidiabetic active principles, quercetin-3-O-galactoside and morroniside, were present in similar amounts in the two extracts, which predicts similar bioactivity.This article is open to POST-PUBLICATION REVIEW.

2018-06-15

Species of the genus Pterocaulon (Asteraceae) are used in different parts of the world for mainly to treat skin and liver diseases, as well as disorders of the respiratory system, among others. This review aims to discuss the present state of the art concerning the ethnobotanical uses, secondary metabolites and biological effects of Pterocaulon species and their chemical components. The available information on the genus Pterocaulon was gathered from scientific databases (Web of Science, Pubmed, ScienceDirect, Scopus, ChemSpider, SciFinder ACS Publications, Wiley Online Library). Information was also obtained from local publications, M.Sc. and Ph.D. dissertations. All studies on the ethnobotany, phytochemistry, pharmacology and toxicology of the plants until December 2017 were included in this review. Approximately 40 coumarins and 30 flavonoids have been isolated from Pterocaulon species. Coumarins have been considered the chemotaxonomic markers in the genus and the most active components. Pharmacological studies carried out with extracts and isolated compounds revealed in vitro bioactivities that include antifungal, antiviral, and cytotoxicity. Most of the pharmacological investigations were not correlated with traditional uses of the plants. Pterocaulon species, a rich source of coumarins, have great ethnomedical potential. Nevertheless, further studies into the pharmacological activities are necessary since none of the purported effects of these plants was fully assessed. In-depth research regarding the toxicity are also required to ensure the safety of these medicinal plants. Copyright © 2018 Elsevier Ireland Ltd. All rights reserved.

Morus alba and active compound oxyresveratrol exert anti-inflammatory activity via inhibition of leukocyte migration involving MEK/ERK signaling

PubMed Central

2013-01-01

Background Morus alba has long been used in traditional Chinese medicine to treat inflammatory diseases; however, the scientific basis for such usage and the mechanism of action are not well understood. This study investigated the action of M. alba on leukocyte migration, one key step in inflammation. Methods Gas chromatography-mass spectrometry (GC-MS) and cluster analyses of supercritical CO2 extracts of three Morus species were performed for chemotaxonomy-aided plant authentication. Phytochemistry and CXCR4-mediated chemotaxis assays were used to characterize the chemical and biological properties of M. alba and its active compound, oxyresveratrol. fluorescence-activated cell sorting (FACS) and Western blot analyses were conducted to determine the mode of action of oxyresveratrol. Results Chemotaxonomy was used to help authenticate M. alba. Chemotaxis-based isolation identified oxyresveratrol as an active component in M. alba. Phytochemical and chemotaxis assays showed that the crude extract, ethyl acetate fraction and oxyresveratrol from M. alba suppressed cell migration of Jurkat T cells in response to SDF-1. Mechanistic study indicated that oxyresveratrol diminished CXCR4-mediated T-cell migration via inhibition of the MEK/ERK signaling cascade. Conclusions A combination of GC-MS and cluster analysis techniques are applicable for authentication of the Morus species. Anti-inflammatory benefits of M. alba and its active compound, oxyresveratrol, may involve the inhibition of CXCR-4-mediated chemotaxis and MEK/ERK pathway in T and other immune cells. PMID:23433072

The aim of the study was to evaluate the phytochemistry and the effect of methanolic root extract (MREt) of Rauwolfia serpentina on alloxan-induced diabetic Wister male mice. Mice were divided in control (distilled water at 1 mL/kg) and alloxan-induced diabetic mice which subdivided into diabetic (distilled water at 1 mL/kg), negative (0.05% dimethyl sulfoxide at 1 mL/kg), positive (glibenclamide at 5 mg/kg) controls, and three test groups (MREt at 10, 30, and 60 mg/kg). All treatments were given orally for 14 days. Qualitatively MREt showed the presence of alkaloids, carbohydrates, flavonoids, glycosides, cardiac glycosides, phlobatannins, resins, saponins, steroids, tannins, and triterpenoids, while quantitatively extract was rich in total phenols. The flavonoids, saponins and alkaloids were also determined in root powder. MREt found effective in improving the body weights, glucose and insulin levels, insulin/glucose ratio, glycosylated and total hemoglobin in test groups as compared to diabetic control. Similarly, significantly decreased levels of total cholesterol, triglycerides, low-density lipoprotein (LDL-c), and very low-density lipoprotein (VLDL-c) cholesterols were found in test groups. Significant lipolysis with improved glycogenesis was also found in liver tissues of all test groups. ALT levels were found normal in all groups. Thus, MREt improves the glycemic, antiatherogenic, coronary risk, and cardioprotective indices in alloxan-induced diabetic mice. PMID:23365565

In Mexico, local empirical knowledge about medicinal properties of plants is the basis for their use as home remedies. It is generally accepted by many people in Mexico and elsewhere in the world that beneficial medicinal effects can be obtained by ingesting plant products. In this review, we focus on the potential pharmacologic bases for herbal plant efficacy, but we also raise concerns about the safety of these agents, which have not been fully assessed. Although numerous randomized clinical trials of herbal medicines have been published and systematic reviews and meta-analyses of these studies are available, generalizations about the efficacy and safety of herbal medicines are clearly not possible. Recent publications have also highlighted the unintended consequences of herbal product use, including morbidity and mortality. It has been found that many phytochemicals have pharmacokinetic or pharmacodynamic interactions with drugs. The present review is limited to some herbal medicines that are native or cultivated in Mexico and that have significant use. We discuss the cultural uses, phytochemistry, pharmacological, and toxicological properties of the following plant species: nopal (Opuntia ficus), peppermint (Mentha piperita), chaparral (Larrea divaricata), dandlion (Taraxacum officinale), mullein (Verbascum densiflorum), chamomile (Matricaria recutita), nettle or stinging nettle (Urtica dioica), passionflower (Passiflora incarnata), linden flower (Tilia europea), and aloe (Aloe vera). We conclude that our knowledge of the therapeutic benefits and risks of some herbal medicines used in Mexico is still limited and efforts to elucidate them should be intensified.

Control of Boreal Forest Soil Microbial Communities and Processes by Plant Secondary Compounds

Leewis, M. C.; Leigh, M. B.

2016-12-01

Plants release an array of secondary plant metabolites (SPMEs), which vary widely between plant species/progenies and may drive shifts in soil microbial community structure and function. We hypothesize that SPMEs released through litterfall and root turnover in the boreal forest control ecosystem carbon cycling by inhibiting microbial decomposition processes, which are overcome partially by increased aromatic biodegradation of microbial communities that also fortuitously prime soils for accelerated biodegradation of contaminants. Soils and litter (stems, roots, senescing leaves) were collected from 3 different birch progenies from Iceland, Finland, and Siberia that have been reported to contain different SPME content (low, medium, high, respectively) due to differences in herbivory pressure over their natural history, as well as black spruce, all growing in a long-term common tree garden at the Kevo Subarctic Field Research Institute, Finland. We characterized the SPME content of these plant progenies and used a variety of traditional microbiological techniques (e.g., enzyme assays, litter decomposition and contaminant biodegradation rates) and molecular techniques (e.g., high-throughput amplicon sequencing for bacteria and fungi) to assess how different levels of SPMEs may correlate to shifts in microbial community structure and function. Microbial communities (bacterial and fungal) significantly varied in composition as well as leaf litter and diesel biodegradation rates, in accordance with the phytochemistry of the trees present. This study offers novel, fundamental information about phytochemical controls on ecosystem processes, resilience to contaminants, and microbial decomposition processes.

Dementia is a chronic neurodegenerative disease causing progressive and gradual impairment of different brain's cognitive functions. The prevalence of dementia is about 3 to 7% in different parts of the world. The aim of this study was to determine the etiologies of dementia according to the Traditional Persian Medicine scientists' viewpoint and introduce their recommended herbal remedies for this disease. The authors explored six main Traditional Persian Medicine textbooks for the disease of dementia, its etiologies and related recommended herbal treatments. Two main keywords of "Lisarghes" and" Nesyan" were searched for this purpose. Medical databases, including PubMed, Scopus, Google Scholar, and Science Direct were searched for related articles published between 1966 and 2016 to review the pharmacological components and active ingredients of suggested herbal medicines. According to the Traditional Persian Medicine, dementia is resulted from brain dystemperament, a condition caused by cold and moist or cold and dry tempers. To treat this disease, Traditional Persian scientists recommended various herbal remedies. Current studies have demonstrated that some of these medicinal plants have beneficial effects for the aforementioned disease, including acetyl cholinesterase inhibitory function, neuroprotective effects, and memory enhancing role. The Traditional Persian Medicine literature suggested different herbal remedies for treating dementia. Modern studies support the usefulness of some of these medicines. However, the effect of a large number of these remedies has remained unexamined, a matter which needs to be investigated in future researches.

Pittosporum viridiflorum Sims, a Pittosporaceae species, is used extensively in African traditional medicine (ATM) by various tribes. This review is an appraisal of the information concerning the description, distribution, conservation status, traditional uses, phytochemistry, pharmacology and toxicology of this species with the aim of reconciling it with its traditional use. A wide-ranging literature search was conducted using database platforms such as Scopus, Google Scholar, Web of Science, ScienceDirect, PubMed and books including local reports and thesis submissions. Ten categories to which P. viridiflorum finds use in traditional medicine (TM) were found, and they include well-being, wounds, treatment of veterinary ailments, gastrointestinal and sexually transmitted diseases, kidney, circulatory and inflammatory disorders, as well as diseases such as cancer, tuberculosis, and malaria. Pharmacological tests conducted include those investigating antimicrobial, antidiarrhoeal, antimalarial, anticancer, anti-inflammatory, antioxidant and acaricidal properties. Promising activity was shown in a number of assays. Toxicological effects have also been reported from this species. However, it is recommended to conduct a detailed toxicological study, including genotoxicity, as this has not yet been evaluated. Compound(s) with antimalarial, anticancer and acaricidal properties have been isolated from P. viridiflorum. The collective pharmacological and phytochemical properties of P. viridiflorum gives credence to the use of this plant species against various diseases in ATM, thus steering significant interest towards in vivo studies and further research.

Ayurvedic medicinal plants for Alzheimer's disease: a review

PubMed Central

2012-01-01

Alzheimer's disease is an age-associated, irreversible, progressive neurodegenerative disease that is characterized by severe memory loss, unusual behavior, personality changes, and a decline in cognitive function. No cure for Alzheimer's exists, and the drugs currently available to treat the disease have limited effectiveness. It is believed that therapeutic intervention that could postpone the onset or progression of Alzheimer's disease would dramatically reduce the number of cases in the next 50 years. Ayurvedic medicinal plants have been the single most productive source of leads for the development of drugs, and over a hundred new products are already in clinical development. Indeed, several scientific studies have described the use of various Ayurvedic medicinal plants and their constituents for treatment of Alzheimer's disease. Although the exact mechanism of their action is still not clear, phytochemical studies of the different parts of the plants have shown the presence of many valuable compounds, such as lignans, flavonoids, tannins, polyphenols, triterpenes, sterols, and alkaloids, that show a wide spectrum of pharmacological activities, including anti-inflammatory, anti-amyloidogenic, anti-cholinesterase, hypolipidemic, and antioxidant effects. This review gathers research on various medicinal plants that have shown promise in reversing the Alzheimer's disease pathology. The report summarizes information concerning the phytochemistry, biological, and cellular activities and clinical applications of these various plants in order to provide sufficient baseline information that could be used in drug discovery campaigns and development process, thereby providing new functional leads for Alzheimer's disease.

Recently, a great deal of interest has been developed to isolate and investigate novel bioactive components from natural resources with health beneficial effects. Saffron is the dried stigma of Crocus sativus L. and has been used for centuries in traditional medicine mainly for its healing properties, as well as for the treatment of various pathological conditions. Objectives of the present review are to unravel its therapeutic properties and investigate the potential applications of saffron in contemporary therapy of a wide spectrum of diseases and summarize previous and current evidence regarding the biological/pharmacological activities of saffron and its active ingredients and their possible therapeutic uses. Recent phytochemistry and pharmacological experiments have indicated that crocin and safranal, the major active ingredients of saffron, exert important actions, such as antioxidant, anti-tumor, anti-diabetic, anti-inflammatory and anti-atherosclerotic. Unfortunately, the vast majority of those data derive from in vitro studies, whereas a limited number of in vivo experiments support the aforementioned effects. In addition to studies with mechanistic implications, very few clinical trials provide preliminary evidence of saffron potentiality to alleviate depression and increase cognitive function in patients with Alzheimer's disease. The history and structural features of saffron constituents are given in the first part of the review, followed by a comprehensive and critical presentation of the published preclinical and clinical studies and review papers on the pharmacology and possible therapeutic uses of saffron and its main active components crocin and safranal. © 2015 Royal Pharmaceutical Society.

Medicinal plants have attracted global attention for their hidden therapeutic potential. Clinacanthus nutans (Burm.f) Lindau (Acanthaceae) (CN) is endemic in Southeast Asia. CN contains phytochemicals common to medicinal plants, such as flavonoids. Traditionally, CN has been used for a broad range of human ailments including snake bites and cancer. This article compiles the ethnomedicinal uses of CN and its phytochemistry, and thus provides a phytochemical library of CN. It also discusses the known pharmacological and biological effects of CN to enable better investigation of CN. This literature review was limited to articles and websites published in the English language. MEDLINE and Google Scholar databases were searched from December 2014 to September 2016 using the following keywords: "Clinacanthus nutans" and "Belalai gajah". The results were reviewed to identify relevant articles. Information from relevant selected studies was systematically analyzed from contemporary ethnopharmacological sources, evaluated against scientific literature, and extracted into tables. The literature search yielded 124 articles which were then further scrutinized revealing the promising biological activities of CN, including antimicrobial, antiproliferative, antitumorigenic and anti-inflammatory effects. Few articles discussed the mechanisms for these pharmacological activities. Furthermore, CN was beneficial in small-scale clinical trials for genital Herpes and aphthous stomatitis. Despite the rich ethnomedicinal knowledge behind the traditional uses of CN, the current scientific evidence to support these claims remains scant. More research is still needed to validate these medicinal claims, beginning by increasing the understanding of the biological actions of this plant.

Several roots or rhizomes of rubiaceous species are reportedly used as the emetic and antiamoebic drug ipecac. True ipecac (Carapichea ipecacuanha) is chemically well characterized, in contrast to striated or false ipecac derived from the rhizomes of Ronabea emetica (syn. Psychotria emetica). Besides its previous use as substitute of ipecac, the latter species is applied in traditional medicine of Panama and fruits of its relative Ronabea latifolia are reported as curare additives from Colombia. Compounds of Ronabea emetica were isolated using standard chromatographic techniques, and structurally characterized by NMR spectroscopy and mass spectrometry. Organ specific distribution in Ronabea emetica as well as in Ronabea latifolia was further assessed by comparative HPLC analysis. Four iridoid-glucosides, asperuloside (1), 6α-hydroxygeniposide (2), deacetylasperulosidic acid (3) and asperulosidic acid (4) were extracted from leaves of Ronabea emetica. Rhizomes, used in traditional medicine, were dominated by 3. HPLC profiles of Ronabea latifolia were largely corresponding. These results contrast to the general tendency of producing emetine-type and indole alkaloids in species of Psychotria and closely related genera and merit chemotaxonomic significance, characterizing the newly delimited genus Ronabea. The aim of the work was to resolve the historic problem of adulteration of ipecac by establishing the chemical profile of Ronabea emetica, the false ipecac, as one of its less known sources. The paper demonstrates that different sources of ipecac can be distinguished by their phytochemistry, thus contributing to identifying adulterations of true ipecac.

In Mexico, local empirical knowledge about medicinal properties of plants is the basis for their use as home remedies. It is generally accepted by many people in Mexico and elsewhere in the world that beneficial medicinal effects can be obtained by ingesting plant products. In this review, we focus on the potential pharmacologic bases for herbal plant efficacy, but we also raise concerns about the safety of these agents, which have not been fully assessed. Although numerous randomized clinical trials of herbal medicines have been published and systematic reviews and meta-analyses of these studies are available, generalizations about the efficacy and safety of herbal medicines are clearly not possible. Recent publications have also highlighted the unintended consequences of herbal product use, including morbidity and mortality. It has been found that many phytochemicals have pharmacokinetic or pharmacodynamic interactions with drugs. The present review is limited to some herbal medicine that are native or cultivated in Mexico and that have significant use. We discuss the cultural uses, phytochemistry, pharmacological and toxicological properties of the following following plant species: Nopal (Opuntia ficus), Peppermint (Mentha piperita), Chaparral (Larrea divaricata), Dandlion (Taraxacum officinale), Mullein (Verbascum densiflorum), Chamomile (Matricaria recutita), Nettle or Stinging Nettle (Urtica dioica), Passionflower (Passiflora incarmata), Linden Flower (Tilia europea), and Aloa (Aloa vera). We conclude that our knowledge of the therapeutic benefits and risks of some herbal medicines used in Mexico is still limited and efforts to elucidate them should be intensified. PMID:18037151

Loloh are herbal drinks produced and consumed exclusively in Bali (Indonesia) to prevent and treat different ailments. This is the first study to document plants species used as Loloh, reporting the phytochemical components and pharmacological properties of the most cited plants. Documenting the plants used in herbal drinks in Bali by local communities to treat various ailments (providing some information on phytochemistry and pharmacology of the most interesting plants). Ethnobotanical data were obtained through semi-structured interviews (individual and group discussions) and questionnaires. Plant specimens were collected, identified and made into herbarium vouchers. A total of 51 plants species (belonging to 32 families) have been documented for their use in the various preparation of Loloh. Different plants and plant parts are used to prepare Loloh to treat heartburn, fever, diarrhea, hypertension, aphthous stomatitis (canker sores), and other minor health problems. These plants are mainly prepared as decoctions, are juiced or simply added to the preparation. The most cited plants (>30 informants) are Alstonia scholaris (L.) R. Br., Blumea balsamifera (L.) DC., Cinnamomum burmanni Nees ex Bl., and Piper betle L. These plants are well studied with multiple demonstrated pharmacological activities (e.g., antimicrobial, anticancer, antidiabetic). The Balinese communities still preserve a rich ethnobotanical knowledge. Several species are well known for their pharmacological properties, but some [such as Pneumatopteris callosa (Blume) Nakai and Dendrocnide stimulans (L. f.) Chew] are understudied and could be promising candidates for further research. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Medicinal plants are part and parcel of human society to combat diseases from the dawn of civilization. Terminalia chebula Retz. (Fam. Combretaceae), is called the ‘King of Medicine’ in Tibet and is always listed at the top of the list of ‘Ayurvedic Materia Medica’ because of its extraordinary power of healing. The whole plant possesses high medicinal value and traditionally used for the treatment of various ailments for human beings. Some of the folklore people used this plant in the treatment of asthma, sore throat, vomiting, hiccough, diarrhea, dysentery, bleeding piles, ulcers, gout, heart and bladder diseases. The plant has been demonstrated to possess multiple pharmacological and medicinal activities, such as antioxidant, antimicrobial, antidiabetic, hepatoprotective, anti-inflammatory, antimutagenic, antiproliferative, radioprotective, cardioprotective, antiarthritic, anticaries, gastrointestinal motility and wound healing activity. But no systematic updated information on the therapeutic effectiveness of Terminalia chebula, a popular herbal remedy in India and South-East Asia has so far been reported. This review highlights an updated information particularly on the phytochemistry and various pharmacological and medicinal properties of Terminalia chebula Retz. and some of its isolated compounds, along with their safety evaluation. This may provide incentive for proper evaluation of the plant as medicinal agent against the human diseases and also to bridge the lacunae in the existing literature and future scope which may offer immense opportunity for researchers engaged in validation of the traditional claims and development of safe and effective botanical medicine.

The fruit of Illicium verum Hook. f. (Chinese star anise) has long been used in traditional Chinese medicine and food industry with the actions of dispelling cold, regulating the flow of Qi and relieving pain. A bibliographic investigation was carried out by analyzing recognized books including Chinese herbal classic, and worldwide accepted scientific databases (Pubmed, SciFinder, Scopus and Web of Science) were searched for the available information on I. verum. I. verum is an aromatic evergreen tree of the family Illiciaceae. It is sometimes contaminated with highly toxic Japanese star anise (I. anisatum L.) and poisonous star anise (I. lanceolatum A. C. Smith), which contain several neurotoxic sesquiterpenes. Traditional uses of I. verum are recorded throughout Asia and Northern America, where it has been used for more than 10 types of disorders. Numerous compounds including volatiles, seco-prezizaane-type sesquiterpenes, phenylpropanoids, lignans, flavonoids and other constituents have been identified from I. verum. Modern pharmacology studies demonstrated that its crude extracts and active compounds possess wide pharmacological actions, especially in antimicrobial, antioxidant, insecticidal, analgesic, sedative and convulsive activities. In addition, it is the major source of shikimic acid, a primary ingredient in the antiflu drug (Tamiflu). This review summarizes the up-to-date and comprehensive information concerning the botany, traditional use, phytochemistry and pharmacology of I. verum together with the toxicology, and discusses the possible trend and scope for future research of I. verum.

2015-10-14

The present state of knowledge concerning developmental processes and the secondary metabolism of saffron, Crocus sativus L. (Iridaceae), along with the genes involved in these processes so far known, is reviewed. Flowers and corms constitute the most valuable parts of saffron. Corm and flower development are two key aspects to be studied in saffron to increase the yield and quality of the spice, to raise its reproductive rate, and to implement new production systems. Important knowledge about the physiology of flowering and vegetative growth has been acquired in recent years, but there is still only limited information on molecular mechanisms controlling these processes. Although some genes involved in flower formation and meristem transition in other species have been isolated in saffron, the role of these genes in this species awaits further progress. Also, genes related with the synthesis pathway of abscisic acid and strigolactones, growth regulators related with bud endodormancy and apical dominance (paradormancy), have been isolated. However, the in-depth understanding of these processes as well as of corm development is far from being achieved. By contrast, saffron phytochemicals have been widely studied. The different flower tissues and the corm have been proved to be an important source of phytochemicals with pharmacological properties. The biotechnological prospects for saffron are here reviewed on the basis of the discovery of the enzymes involved in key aspects of saffron secondary metabolism, and we also analyze the possibility of transferring current knowledge about flowering and vegetative propagation in model species to the Crocus genus.

Towards An Integrative Theory Of Consciousness: Part 1 (Neurobiological And Cognitive Models)

PubMed Central

De Sousa, Avinash

2013-01-01

The study of consciousness is poised today at interesting crossroads. There has been a surge of research into various neurobiological underpinnings of consciousness in the past decade. The present article looks at the theories regarding this complex phenomenon, especially the ones that neurobiology, cognitive neuroscience and cognitive psychology have to offer. We will first discuss the origin and etymology of word consciousness and its usage. Neurobiological correlates of consciousness are discussed with structures like the ascending reticular activating system, the amygdala, the cerebellum, the thalamus, the frontoparietal circuits, the prefrontal cortex and the precuneus. The cellular and microlevel theories of consciousness and cerebral activity at the neuronal level contributing to consciousness are highlighted, along with the various theories posited in this area. The role of neuronal assemblies and circuits along with firing patterns and their ramifications for the understanding of consciousness are discussed. A section on the role of anaesthesia and its links to consciousness is presented, along with details of split-brain studies in consciousness and altered states of awareness, including the vegetative states. The article finally discusses the progress cognitive psychology has made in identifying and theorising various perspectives of consciousness, perceptual awareness and conscious processing. Both recent and past researches are highlighted. The importance and salient features of each theory are discussed along with the pitfalls, if present. A need for integration of various theories to understand consciousness from a holistic perspective is stressed, to enable one to reach a theory that explains the ultimate neurobiology of consciousness.

Uro-words making history: ureter and urethra.

PubMed

Marx, Franz Josef; Karenberg, Axel

2010-06-15

We comprehensively review the history of the terms "ureter" and "urethra" from 700 BC to the present. Using a case study approach, ancient medical texts were analyzed to clarify the etymology and use of both terms. In addition, selected anatomy textbooks from the 15th to 17th centuries were searched to identify and compare descriptions, illustrations, and various expressions used by contemporary authors to designate the upper and lower parts of the urinary tract. The Ancient Greek words "ureter" and "urethra" appear early in Hippocratic and Aristotelian writings. However, both terms designated what we today call the urethra. It was only with increasing anatomical knowledge in Greek medical texts after the 1st century AD that definitions of these words evolved similar to those we employ today. Numerous synonyms were used which served as a basis for translation into Arabic and later Latin during the transfer of ancient knowledge to the cultures of the medieval period. When Greek original texts and their Arabic-Latin version were compared during the Renaissance, this led to terminological confusion which could only be gradually overcome. Around the year 1600, the use of the latinized terms "ureter" and "urethra" became generally accepted. The dissemination of these terms in modern national languages and the emergence of clinical derivatives complete this historical development. The history of the terms "ureter" and "urethra" is exemplary of the difficulties with which the development of a precise urologic terminology had to struggle. The story behind the words also clarifies why even today we still have imprecise or misleading terms.

[Qualitative research about euthanasia concept, between Spanish doctors].

The decriminalisation of euthanasia and assisted medical suicide has generated a continuous debate. The terminological confusion is one of the main difficulties in obtaining medical practice consensus. The objective of this study was to determine whether the terms of Euthanasia and physician assisted suicide are used with the same meaning by doctors in Extremadura (Spain). A qualitative study was conducted using two focus groups in which doctors from different specialties who attended a large number of terminal patients participated. No other focus group was required due to saturation. The sessions were tape recorded and transcribed by two experts in qualitative methodology. Atlas.ti software was used for the analysis. We were advised by the "Health Care at the end of life" Group of the Organizacion Médica Colegial of Spain. Terminological confusion was verified in: 1) The mixture of etymological, functional and social concepts, 2) the term Passive Euthanasia, 3) the association between euthanasia and physician assisted suicide, 4) the confusion with the equivalent "wish to hasten death", and 5) the difficulty of differentiating sedation with Euthanasia. There was consensus on some aspects: a) Full voluntariness, b) the condition of terminal illness, and c) the condition of unbearable symptoms. Conceptual variability persists in relation to the concept of Euthanasia, and is particularly noticeable in the persistence of the concept of passive euthanasia. It would be desirable to achieve a common language to assign a precise meaning to these words to help doctors in their professional practice. Copyright © 2015 SECA. Published by Elsevier Espana.

The history of Latin terminology of human skeletal muscles (from Vesalius to the present).

PubMed

Musil, Vladimir; Suchomel, Zdenek; Malinova, Petra; Stingl, Josef; Vlcek, Martin; Vacha, Marek

2015-01-01

The aim of this literary search was to chart the etymology of 32 selected human skeletal muscles, representative of all body regions. In researching this study, analysis of 15 influential Latin and German anatomical textbooks, dating from the sixteenth to the nineteenth century, was undertaken, as well as reference to four versions of the official Latin anatomical terminologies. Particular emphasis has been placed on the historical development of muscular nomenclature, and the subsequent division of these data into groups, defined by similarities in the evolution of their names into the modern form. The first group represents examples of muscles whose names have not changed since their introduction by Vesalius (1543). The second group comprises muscles which earned their definitive names during the seventeenth and eighteenth century. The third group is defined by acceptance into common anatomical vernacular by the late nineteenth century, including those outlined in the first official Latin terminology (B.N.A.) of 1895. The final group is reserved for six extra-ocular muscles with a particularly poetic history, favoured and popularised by the anatomical giants of late Renaissance and 1,700 s. As this study will demonstrate, it is evident that up until introduction of the B.N.A. there was an extremely liberal approach to naming muscles, deserving great respect in the retrospective terminological studies if complete and relevant results are to be achieved. Without this knowledge of the vernacular of the ages past, modern researchers can find themselves 'reinventing the wheel' in looking for their answers.

Tracing the origins of success: implications for successful aging.

PubMed

Peterson, Nora M; Martin, Peter

2015-02-01

This paper addresses the debate about the use of the term "successful aging" from a humanistic, rather than behavioral, perspective. It attempts to uncover what success, a term frequently associated with aging, is: how can it be defined and when did it first come into use? In this paper, we draw from a number of humanistic perspectives, including the historical and linguistic, in order to explore the evolution of the term "success." We believe that words and concepts have deep implications for how concepts (such as aging) are culturally and historically perceived. We take a comparative approach, turning to the etymological roots of this term in British, French, and German literature. According to the earliest entries of the term in the Oxford English Dictionary, events can have good or bad success. Another definition marks success as outcome oriented. Often used in the context of war, religion, and medicine, the neutral, but often negative, use of "success" in literature of the Renaissance demonstrates the tensions that surround the word, and suggests that success is something to be approached carefully. Ignoring the ambiguous origins of success erases the fact that aging in earlier centuries echoes much of the same ambivalence with which many people discuss it today. Attending to the origins of success can help gerontologists understand the humanistic tradition behind their inquiry into what successful aging means today. © The Author 2014.

Contract theories and partnership in health care. A philosophical inquiry to the philosophy of John Rawls and Seyla Benhabib.

PubMed

Määttä, Sylvia; Lützén, Kim; Öresland, Stina

2017-07-01

Over the last 20 years, a paternalistic view in health care has been losing ground. The question about less asymmetrical positions in the healthcare professional-patient relationship is, for example, being addressed by the increased emphasis on person-centred care, promoted in disciplines such as medicine and nursing. Partnership is considered as a key component in person-centred care. Although the previous studies have addressed the attributes inherent in partnership, there is still potential for further discussion on how the various interpretations of partnership influence their use in healthcare literature. A vague understanding might also affect education and evaluation. As we see it, the philosophical underpinnings of the idea of partnership have not been sufficiently explored and discussed. The study reveals that partnership originates in the term "partener" defined as a relationship between individuals or groups characterized by cooperation and responsibility. Etymologically speaking, partnership is hence bound by a contract, which in this study is discussed in the frame of Rawls' contract theory, which in turn intersects with Benhabib and her distinction between "the abstract" and "the concrete Other." Further, the expression "equal partnership," which often appears in the context of person-centredness, is explored in relation to the philosophies of Rawls and Benhabib. The opportunity for partnership, as well as the risk of partnership becoming a tempting magnet with a vague and imprecise meaning, is discussed. Without exploration, reflection and discussion of the philosophical underpinnings, partnership carries a substantial risk of becoming an indistinct idea used in health care. © 2016 John Wiley & Sons Ltd.

Influence of Global Atmospheric Change on the Feeding Behavior and Growth Performance of a Mammalian Herbivore, Microtus ochrogaster

Habeck, Christopher W.; Lindroth, Richard L.

2013-01-01

Global atmospheric change is influencing the quality of plants as a resource for herbivores. We investigated the impacts of elevated carbon dioxide (CO2) and ozone (O3) on the phytochemistry of two forbs, Solidago canadensis and Taraxacum officinale, and the subsequent feeding behavior and growth performance of weanling prairie voles (Microtus ochrogaster) feeding on those plants. Plants for the chemical analyses and feeding trials were harvested from the understory of control (ambient air), elevated CO2 (560 µl CO2 l−1), and elevated O3 (ambient × 1.5) rings at the Aspen FACE (Free Air CO2 Enrichment) site near Rhinelander, Wisconsin. We assigned individual voles to receive plants from only one FACE ring and recorded plant consumption and weanling body mass for seven days. Elevated CO2 and O3 altered the foliar chemistry of both forbs, but only female weanling voles on the O3 diet showed negative responses to these changes. Elevated CO2 increased the fiber fractions of both plant species, whereas O3 fumigation elicited strong responses among many phytochemical components, most notably increasing the carbon-to-nitrogen ratio by 40% and decreasing N by 26%. Consumption did not differ between plant species or among fumigation treatments. Male voles were unaffected by the fumigation treatments, whereas female voles grew 36% less than controls when fed O3-grown plants. These results demonstrate that global atmospheric change has the potential to affect the performance of a mammalian herbivore through changes in plant chemistry. PMID:23977345

Medicinal plants, having great elementary and therapeutic importance, are the gift to mankind to acquire healthy lifestyle. Emblica officinalis Gaertn. or Phyllanthus emblica Linn. (Euphorbeaceae), commonly known as Indian gooseberry or Amla, has superior value in entirely indigenous traditional system of medicine, including folklore Ayurveda, for medicinal and nutritional purposes to build up lost vitality and vigor. In this article, numerous phytochemicals isolated from E. officinalis and its ethnomedical and pharmacological potentials with molecular mechanisms are briefly deliberated and recapitulated. The information documented in the present review was collected from more than 270 articles, published or accepted in the last five to six decades, and more than 20 e-books using various online database. Additional information was obtained from various botanical books and dissertations. The extracts from various parts of E. officinalis, especially fruit, contain numerous phytoconstituents viz. higher amount of polyphenols like gallic acid, ellagic acid, different tannins, minerals, vitamins, amino acids, fixed oils, and flavonoids like rutin and quercetin. The extract or plant is identified to be efficacious against diversified ailments like inflammation, cancer, osteoporosis, neurological disorders, hypertension together with lifestyle diseases, parasitic and other infectious disorders. These actions are attributed to either regulation of various molecular pathway involved in several pathophysiologies or antioxidant property which prevents the damage of cellular compartments from oxidative stress. However, serious efforts are required in systemic research to identify, isolate and evaluate the chemical constituents for nutritional and therapeutic potentials. Copyright © 2016 Elsevier Ltd.

It has been well established that complex mixtures of phytochemicals in fruits and vegetables can be beneficial for human health. Moreover, it is becoming increasingly apparent that phytochemicals can influence the pharmacological activity of drugs by modifying their absorption characteristics through interactions with drug transporters as well as drug-metabolizing enzyme systems. Such effects are more likely to occur in the intestine and liver, where high concentrations of phytochemicals may occur. Alterations in cytochrome P450 and other enzyme activities may influence the fate of drugs subject to extensive first-pass metabolism. Although numerous studies of nutrient-drug interactions have been published and systematic reviews and meta-analyses of these studies are available, no generalizations on the effect of nutrient-drug interactions on drug bioavailability are currently available. Several publications have highlighted the unintended consequences of the combined use of nutrients and drugs. Many phytochemicals have been shown to have pharmacokinetic interactions with drugs. The present review is limited to commonly consumed fruits and vegetables with significant beneficial effects as nutrients and components in folk medicine. Here, we discuss the phytochemistry and pharmacokinetic interactions of the following fruit and vegetables: grapefruit, orange, tangerine, grapes, cranberry, pomegranate, mango, guava, black raspberry, black mulberry, apple, broccoli, cauliflower, watercress, spinach, tomato, carrot, and avocado. We conclude that our knowledge of the potential risk of nutrient-drug interactions is still limited. Therefore, efforts to elucidate potential risks resulting from food-drug interactions should be intensified in order to prevent undesired and harmful clinical consequences. © 2011 Institute of Food Technologists®

Tea, one of the world's most important beverage crops, provides numerous secondary metabolites that account for its rich taste and health benefits. Here we present a high-quality sequence of the genome of tea, Camellia sinensis var. sinensis (CSS), using both Illumina and PacBio sequencing technologies. At least 64% of the 3.1-Gb genome assembly consists of repetitive sequences, and the rest yields 33,932 high-confidence predictions of encoded proteins. Divergence between two major lineages, CSS and Camellia sinensis var. assamica (CSA), is calculated to ∼0.38 to 1.54 million years ago (Mya). Analysis of genic collinearity reveals that the tea genome is the product of two rounds of whole-genome duplications (WGDs) that occurred ∼30 to 40 and ∼90 to 100 Mya. We provide evidence that these WGD events, and subsequent paralogous duplications, had major impacts on the copy numbers of secondary metabolite genes, particularly genes critical to producing three key quality compounds: catechins, theanine, and caffeine. Analyses of transcriptome and phytochemistry data show that amplification and transcriptional divergence of genes encoding a large acyltransferase family and leucoanthocyanidin reductases are associated with the characteristic young leaf accumulation of monomeric galloylated catechins in tea, while functional divergence of a single member of the glutamine synthetase gene family yielded theanine synthetase. This genome sequence will facilitate understanding of tea genome evolution and tea metabolite pathways, and will promote germplasm utilization for breeding improved tea varieties.

Earlier studies reported serotonergic activity for cimicifugic acids (CA) isolated from Cimicifuga racemosa. The discovery of strongly basic alkaloids, cimipronidines, from the active extract partition and evaluation of previously employed work-up procedures has led to the hypothesis of strong acid/base association in the extract. Re-isolation of the CAs was desired to permit further detailed studies. Based on the acid/base association hypothesis, a new separation scheme of the active partition was required, which separates acids from associated bases. A new 5-HT(7) bioassay guided work-up procedure was developed that concentrates activity into one partition. The latter was subjected to a new two-step centrifugal partitioning chromatography (CPC) method, which applies pH zone refinement gradient (pHZR CPC) to dissociate the acid/base complexes. The resulting CA fraction was subjected to a second CPC step. Fractions and compounds were monitored by (1)H NMR using a structure-based spin-pattern analysis facilitating dereplication of the known acids. Bioassay results were obtained for the pHZR CPC fractions and for purified CAs. A new CA was characterised. While none of the pure CAs was active, the serotonergic activity was concentrated in a single pHZR CPC fraction, which was subsequently shown to contain low levels of the potent 5-HT(7) ligand, N(omega)-methylserotonin. This study shows that CAs are not responsible for serotonergic activity in black cohosh. New phytochemical methodology (pHZR CPC) and a sensitive dereplication method (LC-MS) led to the identification of N(omega)-methylserotonin as serotonergic active principle.

While none of the pure CAs was active, the serotonergic activity was concentrated in a single pHZR CPC fraction, which was subsequently shown to contain low levels of the potent 5-HT7 ligand, Nω–methylserotonin. Conclusion This study shows that CAs are not responsible for serotonergic activity in black cohosh. New phytochemical methodology (pHZR CPC) and a sensitive dereplication method (LC-MS) led to the identification of Nω–methylserotonin as serotonergic active principle. PMID:19140115

Higher quality magnetic nanoparticles are needed for use as magnetic nanoprobe in medical imaging techniques and cancer therapy. Moreover, the phytochemistry benefits of some Amazonian essential oils have sparked great interest for medical treatments. In this work, a magnetic nanoprobe was developed, allying the biocompatibility and superparamagnetism of iron oxide nanoparticles (SPIONs) with benefits associated with Amazonian oils from Copaiba and Andiroba trees. SPIONs were obtained by two thermal decomposition procedures and different amounts of precursors (iron acetylacetonates). Their characterization was accomplished by Fourier transform infrared spectroscopy, thermogravimetric analysis, transmission electron microscopy (TEM), X-ray diffraction (XRD), Mössbauer spectroscopy and magnetization. The obtained nanoparticles composition and magnetic properties were not affected by the relative proportion of iron(II) and iron(III) in the precursor system. However, when changing the reducing and stabilizing agents the coating layer shows different compositions/relative weight - the more promising SPIONs have a coating mainly composed by oleylamine and an iron oxide:coating wt% ratio of 55:45. Nanoparticles size distributions were very narrow and centred in the average size of 6-7 nm. Cellular assays confirmed the biocompatibility of SPIONs and their effective internalization in human colon cancer cells. Mössbauer/XRD results indicated maghemite as their main iron oxide phase, but traces of magnetite proved to be present. Magnetization saturations of 57 emu/g at 5 K and 42 emu/g at 300 K were achieved. With incorporation of SPIONs into Copaiba and Andiroba essential oils, these values show a 4-fold decrease, but the supermagnetic behaviour is preserved providing the effective formation of a nanofluid.

This is the first study on the phytochemistry, antioxidant, anticholinesterase, and antibacterial activities of Sedum caeruleum L. (Crassulaceae). The objective of this study is to isolate the secondary metabolites and determine the antioxidant, anticholinesterase, and antibacterial activities of S. caeruleum. Six compounds (1-6) were isolated from the extracts of S. caeruleum and elucidated using UV, 1D-, 2D-NMR, and MS techniques. Antioxidant activity was investigated using DPPH(•), CUPRAC, and ferrous-ions chelating assays. Anticholinesterase activity was determined against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes using the Ellman method. Antibacterial activity was performed according to disc diffusion and minimum inhibitory concentration (MIC) methods. Isolated compounds were elucidated as ursolic acid (1), daucosterol (2), β-sitosterol-3-O-β-D-galactopyranoside (3), apigenin (4), apigetrin (5), and apiin (6). The butanol extract exhibited highest antioxidant activity in all tests (IC50 value: 28.35 ± 1.22 µg/mL in DPPH assay, IC50 value: 40.83 ± 2.24 µg/L in metal chelating activity, and IC50 value: 23.52 ± 0.44 µg/L in CUPRAC), and the highest BChE inhibitory activity (IC50 value: 36.89 ± 0.15 µg/L). Moreover, the chloroform extract mildly inhibited (MIC value: 80 µg/mL) the growth of all the tested bacterial strains. Ursolic acid (1), daucosterol (2), β-sitosterol-3-O-β-D-galactopyranoside (3), apigenin (4), apigetrin (5), and apiin (6) were isolated from Sedum caeruleum for the first time. In addition, a correlation was observed between antioxidant and anticholinesterase activities of bioactive ingredients of this plant.
