    This study reports the evaluation of bottled mineral water characteristics using fluorescence spectroscopy (synchronous fluorescence scans and emission spectra) and physico-chemical analyses. Samples from 14 still mineral water brands were compared to 11 tap waters collected from two Romanian cities. Correlation and factor analyses were undertaken to understand the relationships between the individual components. The concentration of major and minor ions showed great variation between the bottled mineral water samples highlighting the diversity of the water intakes, while in the case of tap water the chemical composition was relatively similar for samples collected in the same city. Fluorescence data showed that the mineral water contained low quantities of organic matter. The humic fraction was dominant in all samples, while the microbial fraction was low in most samples. Synchronous fluorescence scans provided more information, regarding the composition of organic matter, compared to emission spectra. The study evidenced the correlation between fluorescence parameters and major elements and highlighted the potential of using fluorescence for qualitative evaluation of the bottled mineral water quality, as a screening method before undertaking complex analyses.

    As travel has become easier and faster, the rate of tropical infections across the world is expected to increase; more students working abroad are going to encounter these diseases more often. Disorders of parasitic etiology play an important role in travel and tropical medicine. The aim of our study was to assess the preclinical students' knowledge regarding parasitic diseases, tropical and travel medicine in the broad context of their professional background. A total of 346 Romanian medical students completed a 13-item questionnaire on the above-mentioned topics. In order to allow for complex evaluation, the questionnaire also included items related to their extracurricular training as well as their future perspectives. The majority of the students (97.7%) declared they had prior knowledge (before studying parasitology) of malaria. Most of the responders (90.2%) knew that a journey in (sub)tropical regions requires adequate prophylactic measures. About a quarter of those interviewed (26.4%) would agree to practice tropical medicine after graduation. They were mainly interested in helping people from underdeveloped countries regardless of remuneration (52.7%). The majority of students (59.8%) wished to practice clinical medicine. It has been observed that fewer than 5% of the questioned students had ever read a scientific paper or book in the field of tropical medicine. English was the most commonly spoken foreign language (92.8%), and 99.1% of students had at least intermediate computer skills. Finally, 71.6% of students would choose to practice the specialty of travel medicine if it were available in Romania. The implementation of appropriate measures towards the globalization of medical teaching in Romanian universities should represent an important issue in this new millennium, in which borders between various nations are starting to fade; otherwise the next generations of physicians will lose the chance to gain wider experiences and share the international

    Context: Eryngium planum, Geum urbanum and Cnicus benedictus plants are an endemic botanical from the Romanian used in folk medicine. Objective: The extracts from three Romanian medicinal plants were investigated for their possible neuroprotective potential. Materials and Methods: Within this study, in vitro neuroprotective activity of the extracts of E. planum, G. urbanum, and C. benedictus plants were investigated via inhibition of acetylcholinesterase (AChE) and tyrosinase (TYR). Total content of phenolics, flavonoids, and proanthocyanidins, high-performance liquid chromatography profile of the main phenolic compounds and antioxidant activity were also determined. Results: Among the tested extracts, the best inhibition of AChE (88.76 ± 5.2%) and TYR (88.5 ± 5.2%) was caused by C. benedictus ethanol (EtOH) extract. The G. urbanum extracts exerted remarkable scavenging effect against 2, 2-diphenyl-1-picrylhydrazyl (IC50, 7.8 ± 0.5 μg/mL aqueous extract, and IC50, 1.3 ± 0.1 μg/mL EtOH extract, respectively) and reducing power, whereas the EtOH extract of C. benedictus showed high scavenging activity (IC50, 0.609 ± 0.04 mg/mL), also. Conclusion: According to our knowledge, this is the first study that demonstrates in vitro neuroprotective effects of E. planum, G. urbanum and C. benedictus. PMID:26109755

    As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

    The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.

    Herbs and minerals are the integral parts of traditional systems of medicine in many countries. Kushta is a form of herbo-mineral preparations used in traditional systems of medicine (Unani and Ayurvedic) of Indo-Pak subcontinent. These preparations have long been used and claimed to be the most effective and potent dosage form. However, there are only few scientific studies carried out on these products because of several reasons mainly being the lack of communication among traditional healers, physicians and scientists. The objective of this paper is to fill this gap by translating the old concepts in modern understanding, providing possible explanation and hypotheses. Some recommendations have also been given to provide the path to initiate research in this area of potential therapeutic value and public concern. PMID:12208190

    This work studied the influence of "maturation" conditions (time and agitation) on aggregation states, gel structure and rheological behaviour of a special kind of pharmaceutical semisolid products made of concentrated clay suspensions in mineral medicinal water. Maturation of the samples was carried out in distilled and sulphated mineral medicinal water, both in static conditions (without agitation) and with manual stirring once a week, during a maximum period of three months. At the measured pH interval (7.5-8.0), three-dimensional band-type networks resulting from face/face contacts were predominant in the laminar (disc-like) clay suspensions, whereas the fibrous (rod-like) particles formed micro-aggregates by van der Waals attractions. The high concentration of solids in the studied systems greatly determined their behaviour. Rod-like sepiolite particles tend to align the major axis in aggregates promoted by low shearing maturation, whereas aggregates of disc-like smectite particles did not have a preferential orientation and their complete swelling required long maturation time, being independent of stirring. Maturation of both kinds of suspensions resulted in improved rheological properties. Laminar clay suspensions became more structured with time, independently from static or dynamic maturation conditions, whereas for fibrous clay periodic agitation was also required. Rheological properties of the studied systems have been related to aggregation states and networking mechanisms, depending on the type of clay minerals constituents. Physical stability of the suspensions was not impaired by the specific composition of the Graena medicinal water.

    2015-01-01

    In clinical medicine, increasing attention is being directed towards the important areas of nutritional biochemistry and toxicant bioaccumulation as they relate to human health and chronic disease. Optimal nutritional status, including healthy levels of vitamin D and essential minerals, is requisite for proper physiological function; conversely, accrual of toxic elements has the potential to impair normal physiology. It is evident that vitamin D intake can facilitate the absorption and assimilation of essential inorganic elements (such as calcium, magnesium, copper, zinc, iron, and selenium) but also the uptake of toxic elements (such as lead, arsenic, aluminum, cobalt, and strontium). Furthermore, sufficiency of essential minerals appears to resist the uptake of toxic metals. This paper explores the literature to determine a suitable clinical approach with regard to vitamin D and essential mineral intake to achieve optimal biological function and to avoid harm in order to prevent and overcome illness. It appears preferable to secure essential mineral status in conjunction with adequate vitamin D, as intake of vitamin D in the absence of mineral sufficiency may result in facilitation of toxic element absorption with potential adverse clinical outcomes.

    Cinnabar, a naturally occurring mercuric sulfide (HgS), has long been used in combination with traditional Chinese medicine as a sedative for more than 2000 years. Up to date, its pharmacological and toxicological effects are still unclear, especially in clinical low-dose and long-term use. In this study, we attempted to elucidate the effects of cinnabar on the time course of changes in locomotor activities, pentobarbital-induced sleeping time, motor equilibrium performance and neurobiochemical activities in mice during 3- to 11-week administration at a clinical dose of 10 mg/kg/day. The results showed that cinnabar was significantly absorbed by gastrointestinal (G-I) tract and transported to brain tissues. The spontaneous locomotor activities of male mice but not female mice were preferentially suppressed. Moreover, frequencies of jump and stereotype-1 episodes were progressively decreased after 3-week oral administration in male and female mice. Pentobarbital-induced sleeping time was prolonged and the retention time on a rotating rod (60 rpm) was reduced after treatment with cinnabar for 6 weeks and then progressively to a greater extent until the 11-week experiment. In addition, the biochemical changes in blood and brain tissues were studied; the inhibition of Na{sup +}/K{sup +}-ATPase activities, increased production of lipid peroxidation (LPO) and nitric oxide (NO) were found with a greater extent in male mice than those in female mice, which were apparently correlated with their differences in the neurological responses observed. In conclusion, these findings, for the first time, provide evidence of the pharmacological and toxicological basis for understanding the sedative and neurotoxic effects of cinnabar used as a Chinese mineral medicine for more than 2000 years.

    Twelve mineral and trace elements (Al, B, Ba, Fe, Zn, Mn, Mg, K, Na, P, Cu, Sr, and Ca) were determined in the herbs and their infusions consumed for medical purposes in Poland such as chamomile (Matricaria chamomilla L.), peppermint (Mentha xpiperita), melissa (Melissa officinalis), sage (Salvia officinalis), nettle (Urtica dioica), linden (Tilia vulgaris) and St. John's wort (Hypericum calycinum). Dry digestion procedure for total concentration and wet digestion procedure for infusions were applied under optimized conditions for dissolution of medicinal herbs. Element concentrations in herbs and their infusions were determined by ICP-OES. The accuracy and precision were verified against NCS DC 73349 - bush branches and leaves certified reference material. The result of total concentrations of elements in herb leaves shows that all herbs contain most of the elements, except K and P, in the μg/g range, and that elemental concentrations varied widely. Moreover, on the basis of experimental results for the extraction efficiencies, the elements in herb infusions were classified into three specific groups: highly-extractable (>55%) including K; moderately-extractable (20-55%) including Mg, Na, P, B, Zn and Cu and poorly-extractable (<20%) including Al, Fe, Mn, Ba, Ca and Sr. The results of analysis were evaluated statistically using ANOVA one-way and three-way analysis of variance, variance correlation test and Spearman's test.

  1. Effect of mineral-enriched diet and medicinal herbs on Fe, Mn, Zn, and Cu uptake in chicken

    2012-01-01

    Background The goal of our study was to evaluate the effects of different medicinal herbs rich in polyphenol (Lemon balm, Sage, St. John's wort and Small-flowered Willowherb) used as dietary supplements on bioaccumulation of some essential metals (Fe, Mn, Zn and Cu) in different chicken meats (liver, legs and breast). Results In different type of chicken meats (liver, legs and breast) from chickens fed with diets enriched in minerals and medicinal herbs, beneficial metals (Fe, Mn, Zn and Cu) were analysed by flame atomic absorption spectrometry. Fe is the predominant metal in liver and Zn is the predominant metal in legs and breast chicken meats. The addition of metal salts in the feed influences the accumulations of all metals in the liver, legs and breast chicken meat with specific difference to the type of metal and meat. The greatest influences were observed in legs meat for Fe and Mn. Under the influence of polyphenol-rich medicinal herbs, accumulation of metals in the liver, legs and breast chicken meat presents specific differences for each medicinal herb, to the control group that received a diet supplemented with metal salts only. Great influence on all metal accumulation factors was observed in diet enriched with sage, which had significantly positive effect for all type of chicken meats. Conclusions Under the influence of medicinal herbs rich in different type of polyphenol, accumulation of metals in the liver, legs and breast chicken meat presents significant differences from the group that received a diet supplemented only with metal salts. Each medicinal herb from diet had a specific influence on the accumulation of metals and generally moderate or poor correlations were observed between total phenols and accumulation of metals. This may be due to antagonism between metal ions and presence of other chelating agents (amino acids and protein) from feeding diets which can act as competitor for complexation of metals and influence accumulation of metals

    Agaricus subrufescens Peck is a well-known Basidiomycota fungus (Royal Sun Agaricus), with rising demand in consumption and production worldwide. This particular mushroom with high medical value has been used successfully in cancer therapy and in the treatment of some bacterial and viral diseases. Four strains of A. subrufescens (Si2.2, 853, 1105, and 2603) were cultivated, and 22 mineral elements of basidiomes (fruit bodies) were analyzed (caps and stipes separately). The data obtained about the mineral compositions were compared to the "reference" Agaricus bisporus (white button mushroom) and to the average of wild growing Agaricus species. The mineral composition of A. subrufescens strains can be characterized by the following: (1) high levels of valuable macroelements, i.e., potassium (28-30,000 mg/kg of dry matter), phosphorus (7-11,000 mg/kg of dry matter), and calcium and magnesium (for both elements, 1,000-1,500 mg/kg of dry matter); (2) significantly higher level of copper (compared to A. bisporus, 70-150 mg/kg of dry matter) and zinc (140-250 mg/kg of dry matter); (3) low quantity of sodium (140-180 mg/kg of dry matter); (4) attention should paid to the detectable amount of cadmium (2-17 mg/kg of dry matter) in strain Si2.2; (5) low or undetectable concentrations of some other poisonous microelements like As, Cr, and V; and (6) the distribution of elements in caps and stipes is characteristic-the majority of beneficial elements have higher contents in caps than in stipes, but some other elements, such as Ca, Fe, and Na, appear in an inverse proportion. In conclusion, it can be said that the mineral composition of A. subrufescens is definitely positive, with the exception of the above-mentioned Cd level.

    Mineral Water (MW) of Pyatigorsk deposit (PD) is united in five genetic groups (operational stocks of 2809,8 m3/day): carbonic and hydrosulphuric, carbonic, carbonic chloride-hydrocarbonate sodium (salt and alkaline), radonic low carbonate, nitrogen-carbonic terms. A variety of MW types is explained by peculiarities of geological structure and hydrogeological conditions of PD. Here on the sites of the development of deep semi-ring splits there are overflows and a mixture of various complexes. Unloading of deep water strikes happens not only on the earth surface in the form of springs but also at the depth in its edging crumbling rocks of Palaeocene and quarternary deposits. As a result of mixture processes of water and its subsequent metamorphization, various types of mineral water of this deposit are formed. Pyatigorsk resort is in a special protected ecologo-resort region which mode allows to keep stability of structure and ecological purity of MW. Nevertheless, MW variability, compositional differences and MW mineralization determining the level of its biological effect demand studying of action mechanisms of both natural MW, and possibility of its modification for range expansion of rehabilitation action. There have been examined biological effects of the course drinking reception In experiment on 80 rats males of the Wistar line biological effects of the course drinking reception of two MW types: "Krasnoarmeyskaya new" (MW1) of sulphate-hydrocarbonate-chloride calcium-sodium structure with the raised contents of iron (3-5 mg/dm3), mineralization of 5,0-5,2 g/dm3, CO2 of 1,3-2,2 g/dm3, daily flow of 10-86 m3/day, temperature from 14 to 370C on the mouth of the well and spring №2 (MW2) low sulphate, low carbonate sulphate-hydrocarbonate-chloride calcium-sodium, mineralization of 5,0 g/l, CO2 of 0,7 g/dm3, H2 of S 0,01 g/dm3.

    process. Furthermore, aqueous leachates of the antibacterial clays effectively kill the bacteria. Progressively heating the clay leads first to dehydration (200°C), then dehydroxylation (550°C or more), and finally to destruction of the clay mineral structure by (~900°C). By identifying the elements lost after each heating step, and testing the bactericidal effect of the heated product, we eliminated many toxins from consideration (e.g., microbes, organic compounds, volatile elements) and identified several redox-sensitive refractory metals that are common among antibacterial clays. We conclude that the pH and oxidation state buffered by the clay mineral surfaces is key to controlling the solution chemistry and redox related reactions occurring at the bacterial cell wall.

    Prof. Dr. Gheorghe Bilaşcu (1863–1926) was one of the founders of the Romanian Faculty of Medicine in Cluj. At this Faculty, in 1919/1920 he created the department and the clinic of dentistry. These two achievements were accomplished for the first time in Romania. Normally, his contribution should have been appreciated both during his life and after his death. Also, his name would be expected to be present in the large majority of Romanian medico-historians dictionaries, treatises, papers etc. Unfortunately, his posthumous appreciation was not as Bilaşcu would have deserved. In our paper we present the recognition of Gh. Bilaşcu’s contributions in the Romanian history of dentistry between 1926–2013. We divided this period into three intervals: from 1926 to 1948, the communist era, and after the anticommunist revolution (1990-present). In the first interval the achievements of Bilaşcu in the field of dentistry were very much appreciated and they were mentioned in a correct way in different medico-historical sources of information. During the communist era the name of Bilaşcu was omitted in some dictionaries, courses etc. After 1990, the important role of Bilaşcu in Romanian dentistry was put into its important place in the majority of Romanian history of medicine sources of information.

    For active substances of botanical, mineral or chemical origin processed in homeopathic medicinal products for human use, the adequate safety principles as with other human medicinal products are applied in line with the European regulatory framework. In homeopathy, nonclinical safety assessment is facing a particular challenge because of a multitude and diversity of source materials used and due to rarely available toxicological data. Thus, current concepts applied by the national regulatory authority in Germany (BfArM) on integrative safety assessment of raw materials used in homeopathic medicinal products involve several evaluation approaches like the use of the Lowest Human Recommended Dose (LHRD), toxicological limit values, Threshold of Toxicological Concern (TTC), data from food regulation or the consideration of unavoidable environmental or dietary background exposure. This publication is intended to further develop and clarify the practical use of these assessment routes by exemplary application on selected homeopathic preparations. In conclusion, the different approaches are considered a very useful scientific and simultaneously pragmatic procedure in differentiated risk assessment of homeopathic medicinal products. Overall, this paper aims to increase the visibility of the safety issues in homeopathy and to stimulate scientific discussion of worldwide existing regulatory concepts on homeopathic medicinal products.

  17. Health risks from lost awareness of cultural behaviours rooted in traditional medicine: An insight in geophagy and mineral intake.

    The term geophagy is applied to the recurrent intentional eating of soil with multifactorial motivation. Geophagists are generally defined by gender (women), age (children), physical status (e.g. pregnancy, lactation, postpartum), social status (people exposed to significant nutritional deficiencies), and culture, but lost awareness of traditional medical meaning of this practice is changing these consumption patterns and increasing health risks. Moreover, although the holistic anthropological perspective recognizes soil consumption as mineral supplementation under certain circumstances, we should consider how the living environment has changed and is changing, along with diet, nutrition requirements, and habits. Therefore, benefits-to-risks ratio of cultural behaviours initiated centuries ago based on traditional medical practices requires deep revision and assessment. Knowledge on minerals metabolism, bioavailability and interactions is required to properly assess the role of geophagy in a balanced and safe intake of micronutrients. Most important, the risk of unbalanced intake of minerals may be serious since the mineralogy and chemistry of geophagic clays are uncontrolled, variable, and difficult to standardize. In addition, other factors (radioactive materials, organic chemicals and soil pathogens) complicate the risk assessment for population groups consuming soil. Since the geophagic practice is expected to persist despite economic development, the paper discusses the multifaceted spectrum of geophagy to highlight critical aspects for risk management.

    Romania is one of the most active seismic countries in Europe, with more than 500 earthquakes occurring every year. The seismic hazard of Romania is relatively high and thus understanding the earthquake phenomena and their effects at the earth surface represents an important step toward the education of population in earthquake affected regions of the country and aims to raise the awareness about the earthquake risk and possible mitigation actions. In this direction, the first national educational project in the field of seismology has recently started in Romania: the ROmanian EDUcational SEISmic NETwork (ROEDUSEIS-NET) project. It involves four partners: the National Institute for Earth Physics as coordinator, the National Institute for Research and Development in Construction, Urban Planning and Sustainable Spatial Development " URBAN - INCERC" Bucharest, the Babeş-Bolyai University (Faculty of Environmental Sciences and Engineering) and the software firm "BETA Software". The project has many educational, scientific and social goals. The main educational objectives are: training students and teachers in the analysis and interpretation of seismological data, preparing of several comprehensive educational materials, designing and testing didactic activities using informatics and web-oriented tools. The scientific objective is to introduce into schools the use of advanced instruments and experimental methods that are usually restricted to research laboratories, with the main product being the creation of an earthquake waveform archive. Thus a large amount of such data will be used by students and teachers for educational purposes. For the social objectives, the project represents an effective instrument for informing and creating an awareness of the seismic risk, for experimentation into the efficacy of scientific communication, and for an increase in the direct involvement of schools and the general public.

    The Romanian astronomy has a more than 2000-year old tradition which is however too little known abroad. The first known archive of astronomical information is the Dacian sanctuary at Sarmizegetusa Regia very similar to that of Stonehenge. After a gap of more than 1000 years sources of astronomical information became to be recovered. They consist mainly of records of astronomical events seen on the Romanian territory. The most safe places to store these genuine archives were the monasteries. We present a classification of the manners of storing astronomical information along with characteristic examples.

    The TV broadcast discusses problems of the modernization of the Romanian astronomical infrastructure, the worst in Eastern Europe. It presents the TELEROM project which proposed to establish a new EU-funded robotic 1,3 m telescope, a project finally rejected by the Astronomical Institute of the Romanian Academy mainly due to the incompetence of the director of this Institute, Dr. Vasile Mioc. It is mentioned that this was the second very promising project failed under the same director, after the project ASTEROS in value of 15 million Euro to establish two modern telescopes was also lost in the recent years. The total cost of the TELEROM project was 1,5 million Euro, according to the agreement with the EU foundation for Regional Development (director Hanns Ruder Institut für Theoretische Astrophysik, Universität Tübingen, Germany - the TELEROM auto-dimissed project director). The facilities from this implementation were very promising in observations of Solar system objects (asteroids, near Earth asteroids, comets), few hundred millions of faint stars, quasars, exoplanets and galaxies. Initially, the director Vasile Mioc and the governing body of the Romanian Astronomical Institute intended to place the telescope in Romania in very bad astroclimatic conditions, namely in the old Feleac observatory, very close to the very highly polluted and quite clouded city of Cluj-Napoca. Many opposite considerations (Dr. Marian Doru Suran from Bucharest, many Romanian astronomers from the Diaspora and a group of 68 astronomers, professors, public outreach people and students from Romania and Diaspora supporting TELEROM) were totally disregarded! Due to refuse to place the telescope in very good astroclimatic conditions (in Canary Islands or Chile) and also due to the impossibility to establish a decent national astronomical observatory in Romania by the direction of the Institute in agreement with the State body of Romania ("Academia Romana" and "Autoritatea Nationala pentru

    Introduction Khadi is an extract that has been used in the preparation of Pooneeru (muppu) in Siddha medicine, but it has not been scientifically evaluated for modern medicinal purposes. The present study examines the preparation and chemical composition of Khadi. Materials and methods According to the method of the palm leaf literature, Karunguruvai and Samba paddy grains were selected for the preparation of Khadi. After removing the husk of the paddies, the cleaned Karunguruvai and Samba rice were processed according to the methods of Swami and Ramasamy Khon. The processed Khadi of Karunguruvai and Samba were analyzed for chemical constituents and were microbiologically assessed. The chemical composition of the paddy grains was also evaluated to compare with the Khadi constituents. Results The major elements of the paddy grains of Karunguruvai and Samba were calcium (CaO) and sodium (Na2O). The predominant trace elements in the Samba rice were nickel and cadmium, whereas Karunguruvai rice contained arsenic, nickel, copper, and cadmium. Samba Khadi contained the trace elements mercury, chromium, lead, copper, and cobalt, whereas Karunguruvai Khadi had a high content of mercury, vanadium, arsenic, nickel, copper, cadmium, barium, and strontium. Karunguruvai Khadi also contained silicon dioxide (SiO2), aluminum oxide (Al2O3), iron oxide (FeO), manganese oxide (MnO), calcium oxide (CaO), and sodium carbonate (Na2O). By contrast, Samba Khadi contained only ferrous oxide (FeO), calcium oxide (CaO), sulfur dioxide (SO2), and carbon dioxide (CO2), which were chemical constituents of the Samba rice. Discussion The composition of Karunguruvai rice was compared with Samba rice and it is identified the absence of heavy metals in Samba as well as Karunguruvai rice. Both of rice powders have more or less similar chemical compounds except phosphorous content. Karunguruvai rice possesses more CaO than Samba rice. The bacterial and fungal activities were assessed during the

    Concentrations of 11 elements (As, Ba, Cd, Cu, Fe, Mn, Ni, Pb, Se, Sr, and Zn) from the medicinal and edible mushroom Wolfiporia extensa were determined using atomic fluorescence spectrometry (for As and Se) and inductively coupled plasma atomic emission spectrometry (for Ba, Cd, Cu, Fe, Mn, Ni, Pb, Sr, and Zn). All the samples were collected from 6 regions of Yuxi in Yunnan Province in the southwest of China and were digested with concentrated nitric acid and hydrogen peroxide in a microwave system. The recovery rates of standard addition ranged from 98.24% to 111.8%; the correlation coefficients were all above 0.999. The amounts of As (0.009-0.41 μg · g-1 dry weight [dw]), Cd (0-0.266 μg · g-1 dw), and Pb (0-2.6 μg · g-1 dw) were below the permissible limits in food that are promulgated by the World Health Organization. All the element concentrations determined in this study were proved at the common level. The result of principal component analysis indicated that 5 principal components were extracted from 11 elements, which revealed 74.7% of all variable information. The results of cluster analysis mainly showed the presence of 3 metal groups. PMID:27649605

    Ra{sup 226} first radionuclide separated from pitchblende in 1898 by Pierre and Marie Curie was successfully used in medicine, industry as in other fields being the only one available radionuclide till 1940 when were produced other radionuclides in accelerators. On long term the use of Ra{sup 226} sealed sources are not any more safe due to: the high specific activity, long half live, decays in Rn{sup 226} gas which increases the internal pressure of capsule leading in time to the leakage, the salts as raw materials from which the sealed sources are manufactured are soluble, there is a leak of information and records on the manufacture and operation. Based on this consideration in Romania regulatory authority did not authorized any more the use of these sealed sources [1]. The paper presents some aspects from Romanian experience related to the collection and conditioning of radium sealed sources. Data relating the radium inventory as well as the arrangements made in order to create a workshop for the conditioning of radium sources are presented. (authors)

    Beer is one of the most popular beverages at worldwide level. Through this study fifteen different types of beer collected from Romanian market were analysed in order to evaluate their mineral, trace element as well the their organic content. Importance of such characterization of beer samples is supported by the fact that their chemical composition can affect both taste and stability of beer, as well the consumer health. Minerals and trace elements analysis were performed on ICP-MS while organic compounds analysis was done through GC-MS. Through ICP-MS analysis, elements as Ca, Na, K and Mg were evidenced at mgṡkg-1 order while elements as Cr, Ba, Co, Ni were detected at lower level. After GC-MS analysis the major volatile compounds that were detected belong to alcohols namely ethanol, propanol, isobutanol, isoamyl alcohol and linalool. Selected fatty acids and esters were evidenced also in the studied beer samples.

    2006-01-01

    Many Italian scholars in the sixteenth century studied minerals. This was not only for the sake of increasing geological knowledge. Minerals, like all other natural phenomena, reflected divine order. Minerals were thought of as a broader category than the lifeless substances found beneath the crust of the earth. Stones, generated in animal and human bodies, were included among minerals, as well. The appearance of kidney stones, gall stones and bladder stones in early modern mineral collections point to the religious motives of the scholars that studied them. In this article, I will examine the mineralogical collection brought together and described by Michele Mercati (1541-1593), the so-called Metallotheca. I will map the circles of physicians, scholars and ecclesiastics in which Mercati lived and functioned. I will then investigate Mercati's descriptions of stones, grown inside animals and men. The specific connections between Mercati and the members of the Oratory of Rome, an influential religious organisation of the Sixteenth century, direct us towards a proper understanding of the significance of Mercati's minerals. Certain minerals, including stones originating in animate bodies, were thought of as approaching the supernatural. The proper attitude for the scholar of nature would then be to turn from curiosity into awe and even veneration. PMID:17153168

    Establishing the tritium level along the Romanian Black Sea Coast, after 10 years of exploitation of the nuclear power plant from Cernavoda, is a first step in evaluating its impact on the Black Sea ecosystem. The monitoring program consists of tritium activity concentration measurement in sea water and precipitation from Black Sea Coast between April 2005 and April 2006. The sampling points were spread over the Danube-Black Sea Canal - before the locks Agigea and Navodari, and Black Sea along the coast to the Bulgarian border. The average tritium concentration in sea water collected from the sampling locations had the value of 11.1 {+-} 2.1 TU, close to tritium concentration in precipitation. Although an operating nuclear power plant exists in the monitored area, the values of tritium concentration in two locations are slightly higher than those recorded elsewhere. To conclude, it could be emphasized that until now, Cernavoda NPP did not had any influence on the tritium concentration of the Black Sea Shore. (authors)

    Multinational companies in Romania have imposed the use of the predominant language, in most cases - English, in professional communication. In contexts related to workplace communication, the main motivation for foreign borrowings is the need to denote concepts and activities. The article focuses on the English language as a wide source for a great number of innovations both at the lexical and the morphological level in the Romanian vocabulary related to business and technology. The aim of the paper is to demonstrate that Romanian language displays a natural disposition towards adopting and adapting foreign words, especially borrowed English terms, in the field of computer science and business without endangering its identity.

    Researchers have conducted considerable experiments on the effectiveness and therapeutic values of Chinese herbs and parts of plants. We should not ignore the significance of natural medicine. The Chinese have been perfecting medicinal therapy based on the raw ingredients of plants/herbs and their derivatives for thousands of years. Chinese practitioners of traditional medicine prescribe medicines based on yin and yang. Traditional medicine is communicated in a verb or written form. Natural resources used in traditional medicine to treat diseases are not limited to just medicinal plants but also include animals, shell fish, and minerals. Parts of plants used in traditional medicine are leaves, stems, flowers, bark, and root. Chinese medicine is the world's oldest continuous surviving tradition. The Chinese experimented with local plants, often resulting in mild to violent reactions. This process allowed them to become familiar with poisonous plants and those that could relieve pain or successfully treat illness. Current allopathic medicines are composed of synthetic compounds copied from natural chemical derivatives, which tend to be more potent than the original compound. Some medicinal plants used to effect conception/contraception include Striga astiatica (contraceptive); Eurycoma longifolia (male virility); and a mixture of lengkuas, mengkudu masak, black pepper seeds, ginger, salt, and 2 eggs (increase libido). Women in Malaysia take jamu to preserve their body shape and to provide nutrition during pregnancy. Praneem causes local cell-mediated immunity in the uterus. Clinical trials of Praneem with or without the hCG vaccine are planned.

    This article presents the results of a series of preliminary comparisons, between the Portuguese and Romanian cultural contexts, on the individualism-collectivism (IND/COL) cultural dimension. The IND/COL was evaluated with the Individualism-Collectivism Questionnaire - ICQ -, constructed in New Zealand by Shulruf, Hattie and Dixon (2003, Anonymous Questionnaire of Self-Attitudes - AQSA), and adapted to the Portuguese and Romanian contexts by Ciochină and Faria (2007), using studies of confirmatory factor analysis. The ICQ composed by 26 items, 15 evaluating the IND scale--with three subscales (Uniqueness, Competition and Responsibility)--, and 11 evaluating the COL scale--with two subscales (Harmony and Advice)--, was administered to 395 subjects, 200 Portuguese and 195 Romanian, 10th and 12th graders. On the whole, in the Portuguese and Romanian samples, the multivariate and univariate statistical analyses evidenced the existence of two independent variables--gender and cultural context--, with significant effects, main and of interaction, on the scales and subscales of the ICQ. The results were discussed taking into consideration the specificities of the educational systems in the two cultural contexts, which are inevitably shaped by socio-cultural factors characteristic of the two countries considered in the present study--Portugal and Romania.

    Abstract The Romanian Protura were studied based on 175 specimens collected from Romania, along with bibliographic data. The main publication on the Romanian proturans was written by M.A. Ionescu (1951), who described 13 species mainly from soil and forest litter from 15 collecting points. The current paper represents the first study at a national level. Faunal data on Protura were obtained from 22 sites, mostly from forests of the Romanian Carpathians and also from a peri-urban area of Bucharest, which had not been studied before. As a result, the Romanian Protura fauna now consists of 27 known taxa in 6 genera and 4 families. Of the 27 taxa, 15 species are new records for Romanian fauna. An identification key to the Romanian Protura species is provided. PMID:26865814

    Knowledge of human leukocyte antigen (HLA) allele frequencies is essential for bone marrow and kidney donor searches. The Romanian Caucasian population is heterogeneous and information on HLA polymorphism has not been well studied. We characterized the HLA genetic profile and allele frequencies of regional populations in Romania. HLA-A, B and DRB1 alleles were examined in 8252 individuals, belonging to the four main regions of Romania. The most common alleles found in the Romanian population are the following: HLA-A*01, A*02, A*03, A*11, A*24; HLA-B*18, B*35, B*44, B*51 and HLA-DRB1*01, DRB1*03, DRB1*07, DRB1*11, DRB1*13, DRB1*15, DRB1*16. More than half of the alleles are non-homogeneously spread in Romania. These results provide a starting point for future analyses of genetic heterogeneity in Romania.

    Clay minerals are important components of the environment and are involved or implicated in processes such as the uptake of pollutants and the release of nutrients and as potential platforms for a number of chemical reactions. Owing to their small particle sizes (typically, on the order of microns or smaller) and mixing with a variety of other minerals and soil components, advanced characterization methods are needed to study their structures, dynamics, and reactivities. In this article, we describe the use of solid-state NMR methods to characterize the structures and chemistries of clay minerals. Early one-pulse magic-angle spinning (MAS) NMR studies of 27Al and 29Si have now been enhanced and extended with new studies utilizing advanced methodologies (such as Multiple Quantum MAS) as well as studies of less-sensitive nuclei. In additional work, the issue of reactivity of clay minerals has been addressed, including studies of reactive surface area in the environment. Utilizations of NMR-sensitive nuclides within the clay minerals themselves, and in molecules that react with specific sites on the clay mineral surfaces, have aided in understanding the reactivity of these complex aluminosilicate systems.

    The Eastern Carpathians contain many mineral water springs that feed famous Romanian health resorts such as Borsec, Biborteni and Vatra Dornei. These waters have been used for their different therapeutic effects. In this work, mineral and spring waters from these Romanian regions were investigated by means of chemical and isotopic (deltaD and delta(18)O) analyses in order to understand the recharge mechanisms and also to determine their origins. Most of the investigated springs are of meteoric origin, having the average deuterium content of the local meteoric water. The higher (18)O content with respect to the Meteoric Water Line (MWL) indicated an exchange reaction with crystalline igneous rocks at depth and with other rocks that the water encounters on its journey back to the surface.

    1998-12-31

    According to ISO 1988 samples must be taken from moving currents by using certain mechanical devices, and, only, exceptionally, by an understanding between party`s, by manually sampling. The principal requirements when designing and constructing a mechanical sampling system are that: it shall be capable of collecting and preparing increments or samples, as the case may be, that are free from relevant bias; it shall maintain this capability under all such conditions of sampling that are stipulated in the relevant specifications and without necessitating that sampling be interrupted for cleaning or maintenance. Actually, coal quality control in Romanian power plants are usually performed by a manual system. In order to meet ISO 1988 requirements, RENEL-GSCI (formerly ICEMENERG) has designed and achieved a falling stream sampler with cutter bucket in accordance with ISO 9411-1 (solid mineral fuels - Mechanical sampling from moving stream) provisions. This device has been installed in the Oradea 2 cogeneration power plant in the coal falling stream at the end of the belt conveyor. When the mechanical sampling installation was commissioned, experiments to check for precision and bias had been out for the installation as a whole. The method of checking for bias was by comparison with stopped-belt sampling. The mechanical sampling device is still under testing. The paper presents the result obtained during the preliminary test period in order to certify the mechanical sampler.

As an economic principle, the fewer resources are used to achieve the expected results, the more effective the supplier. However, the introduction of new medical technologies, many of them more reliable yet more expensive, required a reassessment of the way resources are used at the suppliers' level to produce the expected results, an evaluation based on cost-effectiveness per analysis (or per patient) criteria. Finally, medical services are the tools of the marketing strategy of any medical organizations without which the needs and motivations of the beneficiaries (patients) could not be satisfied. In essence, the entire marketing philosophy is based on the needs and wishes of the people and on concrete solutions to solve them.

  16. Solar eclipses recorded in old Romanian chronicles and notes

    NASA Astrophysics Data System (ADS)

    Stavinschi, Magda; Mioc, Vasile; Débarbat, Suzanne

    Many solar eclipses observed trough history on Romanian territory have been recorded by the witnesses in chronicles and notes. About 100 such records, covering five hundred years (between 1.I.1386 and 6.III.1867), were collected and the respective eclipses were identified. There are records to be noted for the beautiful description of the phenomenon (6.III.1867). There are also records which prove a remarkable accuracy as regards the moments of the eclipse (5.IX.1793, 19.XI.1816). The importance of the latter for astronomy is obvious. Many records provide rich details about various characteristic aspects: the evolution of the phenomenon during the partial eclipse (25.VII.1748, 11.II.1804), the apparition of the stars in the sky during the totality phase (17.VI.1433, 12.VIII.1654, 25.VII.1748), sight damage affecting the imprudent spectators (22.VI.1656), the reactions of the spectators: fright, collective panic (23.IX.1699). Lots of records connect the celestial event with terrestrial calamities, natural (earthquakes, plague, invasions of grasshoppers, floods) or social (wars, kingdom changes). The solar eclipses of 16.III.1485, 12.VIII.1654, 12.V.1706, 28.VII.1851 constitute such examples. Finally, there are records which prove the astronomical cares of certain scientists of the time. For instance, three eclipses which occurred in 1628 (6.I, 1.VII, 24.XII), all invisible in Romania, were recorded by a Romanian 17th century scientist, Stefan Bachner, on the corresponding pages of a calendar for 1559. All these records prove that the celestial phenomena benefitted from particular and constant interest from the Romanian people throughout their history.

    The long-term trends in the water mass thermohaline structure and the effect of Danube River freshwater discharge into the western Black Sea during the last four decades (1971 - 2010) are analyzed using the data collected on the Romanian shelf (NIMRD data base). The variations of the temperature and salinity over the studied period are relatively small. The temperature data reveal a slightly warming trend for the upper mixed layer (UML) while for the shelf cold water (SCW) - identified by the 8˚C upper isotherm depth - thermohaline structure remains practically constant. At the same time the salinity exhibits a decreasing trend in the entire water column.

When Brâncuşi was a student in Bucharest, he produced an ‘écorché’ (flayed man), of which six plaster replicas still exist, two in apparently the original shape and four which have been modified/‘cosmetized’. The two are in the University of Arts in Bucharest, one in the main hall, the other in the classroom used for teaching students. Of the other four, one is in the Museum of Arts and one in the Museum of Natural Sciences of Carol I National College in Craiova (where Gerota graduated in 1885), and one each in the Faculties of Medicine in Cluj Napoca and Iassy. One more probably existed in the Faculty of Medicine in Bucharest, and one in the Faculty of Fine Arts in Iassy but no trace of them could be found. The original clay model was lost (or destroyed during transportation) in the 1930s or 1956. Two variants of the écorché exist: one ‘artistic’ (slender and smoother) in the University of Arts in Bucharest; the other more ‘anatomical’ (muscular, robust, athletic) in Craiova, Cluj and Iassy. Both variants are a very realistic representation of the human muscular system, but with that extra which only a master artist can add. Interestingly, the head of the écorché bears a striking resemblance in attitude and curves to that of Brâncuşi’s famous head of Mademoiselle Pogany. The replicas appear to have been distributed to embellish the capitals of four of the six historical Romanian provinces: Muntenia (Bucharest), Oltenia (Craiova), Moldavia (Iassy), and Transylvania (Cluj).

    In the last 25 years, the introduction of biotechnological methods in hydrometallurgy has created new opportunities and challenges for the mineral processing industry. This was especially true for the production of metal values from mining wastes and low-and-complex-grade mineral resources, which were considered economically not amenable for processing by conventional extraction methods. Using bio-assisted heap, dump and in-situ leaching technologies, copper and uranium extractions gained their first industrial applications. The precious metal industries were the next to adopt the bio-preoxidation technique in the extraction of gold from refractory sulfide-bearing ores and concentrates. A variety of other bioleaching opportunities exist for nickel, cobalt, cadmium and zinc sulfide leaching. Recently developed bioremediation methods and biosorption technologies have shown a good potential for industrial applications to remove trace heavy metal and radionuclide concentrations from contaminated soils, and mining and processing effluents.

    The Romanian Academy of Medical Sciences is the institution that includes the elite of the Romanian medical and pharmaceutical professionals. This is an article of recollection of one of the most outstanding presidents of the Romanian Academy of Medical Sciences, Nicolae Cajal. A distinguished scientist, Cajal accepted not only the task of president of this forum, but was also involved in social and political projects, as chairman of the Jewish Community of Romania, gaining the respect of both his colleagues and the general population. His activity is put in the context of the period in which he lived. PMID:26527998

    Structural patterns in collaboration networks are essential for understanding how new ideas, research practices, innovation or cooperation circulate and develop within academic communities and between and within university departments. In our research, we explore and investigate the structure of the collaboration network formed by the academics working full-time within all the 17 sociology departments across Romania. We show that the collaboration network is sparse and fragmented, and that it constitutes an environment that does not promote the circulation of new ideas and innovation within the field. Although recent years have witnessed an increase in the productivity of Romanian sociologists, there is still ample room for improvement in terms of the interaction infrastructure that ought to link individuals together so that they could maximize their potentials. We also fail to discern evidence in favor of the Matthew effect governing the growth of the network, which suggests scientific success and productivity are not rewarded. Instead, the structural properties of the collaboration network are partly those of a core-periphery network, where the spread of innovation and change can be explained by structural equivalence rather than by interpersonal influence models. We also provide support for the idea that, within the observed network, collaboration is the product of homophily rather than prestige effects. Further research on the subject based on data from other countries in the region is needed to place our results in a comparative framework, in particular to discern whether the behavior of the Romanian sociologist community is unique or rather common.

    Triticale is grown in Romania, mainly, in the hilly regions on the acid poor fertile soils and covers, yearly, around 100-130 thousands ha or 1.5% from the arable land. Since 1971, when the breeding program has been started, up to present, it has been developed an adapted triticale germplasm for the Romanian environmental conditions and 12 new varieties have been registered. Genetic progress for yield, estimated over a 27 years, is by 46 kg ha(1) year(1) or 0.80% year(1), similarly with those realized in the most dynamic triticale breeding programs of the world. The improving of yields has been achieved by an increased number of kernels per spikes, plumpness of kernels, test weight and reduction of the plant height by introduction in the Romanian triticale germplasm of RhtB1b (Rht1) and Ddw1 (Hl) genes. The genetic gain for reduction of plant height, in this period, was estimated at 1.16 cm yr(1). Further progress regarding yield stability under conditions of global climatic changes, a broader genetic diversity for preharvest sprouting (PHS), drought tolerance, earliness, high canopy albedo, diseases resistance, especially for fusarium head blight (low DON content in kernels), leaf rust and BYDV, is required.

    2008-04-01

    In our study we have considered three of the most valuable Romanian red wine grapevine cultivars: Feteasca neagra, Feteasca alba and Novac. We have chosen to study grapevine because grapes and wine are an important part of a healthy diet, and because red grapes have the highest content of proanthocyanidins, that act as antioxidants (free radical scavengers) in the human body. Proanthocyanidins possess anti-mutagenic, anti-tumor, anti-viral activities and they present many other confirmed or potential benefits. Genotyping method was applied in order to asses the genetic profile at 14 microsatellite loci, for two cultivars: Feteasca neagra and Feteasca alba. In order to achieve this, the HPLC-DAD method was used. The content of anthocyans in grape skin from two cultivars - Feteasca neagra and Novac - was measured. Microsatellite markers have been certified as powerful tools for assessing genetic identities and genetic relationships between grapevine gene pools. Genetic characterization of grapevine cultivars can certify their authenticity and purity, two features that have a direct effect on the quality and value of the finished product, the wine. In our country, this is the first attempt in order to establish a genetic profile for valuable Romanian origin grapevine varieties. In some of the 14 microsatellitic loci, Feteasca neagra and Feteasca alba cultivars presented allele size variants different from the values cited in the literature, proving that these cultivars belong to a geographical distinct gene pool. The content of anthocyans in Feteasca neagra grape skin was significantly higher than in Novac.

    2015-01-01

    Background and aims Oral Health Related Quality of Life (OHRQoL) represents a multidimensional structure, being measured by complex instruments, such as the Oral Health Impact Profile (OHIP). The aim of this present study is to develop and test the psychometric properties of an initial Romanian (OHIP-49Ro) version. Methods The original OHIP-49 version was translated using a forward-backward technique into the Romanian OHIP-49Ro, which was applied in an interview form to 150 patients of the Second Medical Clinique of Internal Medicine, Cluj-Napoca. Confirmatory Factor Analysis (CFA) was applied, in order to evaluate the factor structure and construct validity of the OHIP-49Ro. Results The correlations between the OHIP-49Ro subscales were all positive and statistically significant. Cronbach’s Alpha coefficients values are above 0.7 for all subscales, providing support for the internal consistency of OHIP-49Ro scale scores. Regarding the CFA, for the seven factor model, the Bentler scaled chi-square (S–Bχ2) indicated a value of 2193.74 (df=1091; p=0.001), the CFI a value of 0.740, the TLI a value of 0.72 and RMSEA the value of 0.82. Conclusions The results of this study suggest a high internal consistency of the OHIP-49Ro instrument. Due to the correlations between several sets of factors, and the multiple-factorial load for several items, the OHIP-49Ro’s factorial structure requires further research on different samples and in different cultural and educational contexts.

    2014-01-01

    The main goal of this study was to identify acculturation preference profiles using cluster analysis in public and private areas of culture in the host and immigrant populations, and to find out the relationship between these profiles and prejudice levels. Four hundred and ninety-nine Spaniards and 500 Romanians participated in a survey. The sampling of Spaniards was multistage random and the sampling of Romanians was by quota. The results confirm our predictions. Romanians who are less prejudiced against Spaniards prefer assimilation in public areas and integration in private areas. Romanians who are more prejudiced against Spaniards prefer integration in public areas and separation in private areas. Spaniards who are less prejudiced against Romanians prefer integration in both public and private areas. Spaniards who are more prejudiced against Romanians prefer assimilation in both areas.

    Sports Medicine is a relatively new subject in medicine and includes a variety of medical and paramedical fields. Although sports medicine is mistakenly thought to be mainly for sports professionals/athletes, it actually encompasses the entire population, including the active and non-active healthy populations, as well as the sick. Sports medicine also engages amateur sportsmen and strives to promote physical activity and quality of life in the general population. Hence, the field involves all ages from childhood to old age, aiming to preserve and support every person at every age. Sports medicine, which started developing in the 19th century, is today a specialty, primary or secondary, in many countries, while in others it is a fellowship or under the jurisdiction of local or sports authorities. In Israel, the field exists since the 1950's and is advanced. The Sports Medicine Society founded a 3-year course of continued education in sport medicine as part of the Tel-Aviv University Faculty of Medicine. Later on, a fellowship in general Sports Medicine and in Orthopedic Sports Medicine were developed within the Israel Medical Association. A year ago, Israel formally became a member of the global "Exercise is Medicine" foundation, and under this title promotes education for health care providers on exercise prescription. The understanding of the importance of physical activity and fitness as part of a healthy lifestyle is increasing in Israel, as well as the number of amateur athletes, and the profession of sports medicine takes a big part in this process.

    The treatment of diseases with mineral spring water belongs to the oldest medical therapies. The "remedy" mineral water is therefore of importance also within the pharmacy. The present pharmacy historical work examines the impact of the use of mineral waters, as well as of their dried components, as therapeutic agents in the 19th and early 20th centuries, i.e. from approx. 1810 to 1930, as well as the contributions given by pharmacists in the development and analysis of mineral water springs. Beside these aspects, the aim here is also to describe the role played by pharmacists in the production of artificial mineral water as well as in the sale and wholesale of natural and artificial mineral water. In the first part of this work the situation in Switzerland and its surrounding countries, such as Germany, France, Italy and Austria, is discussed. The second part contains a case-study of the particular situation in the Canton Tessin. It is known from the scientific literature published at that time that information on mineral water was frequently reported. Starting from the beginning of the 19th century the number of such publications increased tremendously. The major part of them were publications in scientific journals or contributions to medical and pharmaceutical manuals and reference books. In particular the spa-related literature, such as spa-guides, was of growing interest to a broad public. The inclusion of monographs into the Swiss, the Cantonal as well the foreign pharmacopoeias granted a legal frame for the mineral waters and their dried components. These works are of major importance from a pharmacy historical standpoint and represent a unique proof of historical evidence of the old medicinal drug heritage. The most frequently used therapies based on mineral waters were drinking and bath cures. Several diseases, particularly those of a chronic character, were treated with mineral waters. The positive influence of these cures on the recovery of the patients

    2002-07-01

    This paper examines Romanian bioethics regulations for biomedical sciences, looking in particular at the genetics area as a source for conflict of interest. The analysis is focused on the organizational level, national regulations, the sources for generating conflicts of interest, and management of conflicts. Modern biotechnology and gene technology are among the key technologies of the twenty-first century. The application of gene technology for medical and pharmaceutical purposes is widely accepted by society, but the same cannot be said of the development and application of gene technology in agriculture and food processing. Because the use of a technology in the production and processing of food is regarded more sceptically than in the production of biomedical products, there can be areas of conflict in many cases when communication is undertaken about gene technology in the agro-food sector. Ethical concerns play an important factor in this, but a society's attitude to a developing technology is an amalgam of many effects which are beyond ethics as such. This paper contains a study carried out by the author for the Romanian Association for Consumer Protection about the attitudes of consumers towards genetically modified (GM) foods. This study revealed that in Romania more than 98% of consumers did not know anything about GM foods and frequently were confused about the definitions of these terms. In conclusion, it is necessary to say that there is a low level of knowledge regarding biotechnology in Romania and this is an important reason why there is neither public acceptance of gene technology products nor is there a rejection.

    The aim of this study was to find out what is the prevalence of pathological in Romanian teenagers. We questioned one thousand thirty-two teenagers in Cluj-Napoca and Harghita counties. Participants completed a questionnaire with 40 items including gamblers anonymous twenty questions. The sample included teenagers aged 11-19 years; 65.57% were male and 34.43% were female. The subjects were divided into three groups: non-gambling/recreational gambling or occasional gambling (0-1 positive answers -Level 1)-753 subjects (72.96%) [316 females and 437 males]; problem gambling (2-6 points-Level 2)-243 subjects (23.54%) [43 females and 200 males]; pathological gambling (above 7 points-Level 3)-36 subjects (3.48%) [3 females and 33 males]. The mean age of pathological gamblers was 16.48 years. Gender differences were as expected, males engaging in pathological gambling (91.66% from pathological gamblers) more than females did (8.33% from pathological gamblers). Data revealed that the most encountered games practiced weekly were sport bets and slot machines in the case of 36.11% of the pathological gamblers; lotto, internet casino and pool bets each with 25%, followed by roulette and black-jack with 22.22%.From those who reported practicing gambling at a pathological level 66.66% engaged in alcohol consumption, 13.88% illicit drug use and 19.44% licit drugs. Just 16.66% smoke cigarettes. Data revealed higher rates of prevalence in Romanian teenagers than in other Central and Eastern European countries. A prevalence study at a national level should be designed.

  17. Linking landslide susceptibility to sediment yield in the Romanian Carpathians

    Recent studies revealed the importance of seismic activity in explaining regional patterns of catchment sediment yield (SY). This relation is often explained by the fact that seismic activity induces landslides that contribute to SY. Nevertheless, only a few studies focused on the effects of landslides on SY and even fewer studies have explored the potential of landslide susceptibility as a predictor for SY. The objective of this study is therefore to explore the potential of landslide susceptibility maps to explain the spatial variation of SY in the Romanian Carpathians, a region with moderate to high seismicity. 133 catchments, covering 63% of Romania, for which SY was measured during a period of at least 10 years and for which SY was not significantly affected by upstream reservoirs, were compiled and selected. 78 of these catchments were 'less disturbed', being covered for at least 50% by forest and semi-natural areas and confined to the Carpathian mountains. Landslide susceptibility in each catchment was assessed, using an earlier published state of the art landslide susceptibility map of Romania. Mean landslide susceptibility for each catchment shows a highly significant correlation with SY (r² = 0.44). This indicates that landslides are an important contributor to SY in Romania and suggests that regional and national landslide susceptibility maps can indeed be a useful tool to predict SY. Nevertheless, the susceptibility map did not explain much more of the observed variance in SY than some other individual catchment characteristics such as seismicity (r² = 0.40) and lithology (r² = 0.33). Also taking into account the spatial patterns of landslide susceptibility within the catchment did not significantly improve the observed correlations. Surprisingly, topography showed a nonsignificant correlation with SY, which can be attributed to the overwhelming effect of seismicity and lithology. Overall, our results suggest that seismicity is indeed a highly

    Medical communication in Western-oriented countries is dominated by concepts of shared decision-making and patient autonomy. In interactions with Roma patients, these behavioral patterns rarely seem to be achieved because the culture and ethnicity have often been shown as barriers in establishing an effective and satisfying doctor-patient relationship. The study aims to explore the Roma's beliefs and experiences related to autonomy and decision-making process in the case of a disease with poor prognosis. Forty-eight Roma people from two Romanian counties participated in semi-structured interviews, conducted by a research team from the University of Medicine and Pharmacy of Iasi. Participants were recruited among the chronically ill patients and caregivers. The Roma community opposes informing the terminal patients about their condition, the "silence conspiracy" being widely practiced. The family fully undertakes the right of decision making, thus minimizing the patient's autonomy. We identified ethical dilemmas concerning autonomy, lack of patients' real decision-making power, and paternalistic attitudes exerted firstly by the family and, on demand, by the physician. Instead, the Roma patient benefits from a very active support network, being accompanied at the hospital by numerous relatives. The patient's right to make autonomous decisions promoted in the Western countries and stipulated by the Romanian law has diminished value in the Roma community. For the Roma, the understanding of dignity is not simply individual and personal, but it is closely related to their cultural particularities. Ignoring their cultural values could create conflicts between healthcare providers and community.

    It is only since the late 20th century that Sport and Exercise Medicine has emerged as a distinct entity in health care. In Israel, sports medicine is regulated by a State Law and a sport physician is certified after graduating a structured program. In the past, sports medicine was related to the diagnosis and treatment of injuries encountered by top athletes. In recent years, the scope of sport medicine has broadened to reflect the awareness of modern society of the dangers of physical inactivity. In this perspective the American College of Sport Medicine (ACSM) recently launched a program--"Exercise is Medicine", to promote physical activity in order to improve health and well-being and prevention of diseases through physical activity prescriptions. This program is from doctors and healthcare providers, adjusted to the patient or trainee. The sport physician does not replace a medical specialist, but having a thorough understanding about the etiology of a sport-related injury enables him to better focus on treatment and prevention. Therefore, Team Physicians in Elite Sport often play a role regarding not only the medical care of athletes, but also in the physiological monitoring of the athlete and correcting aberrations, to achieve peak physical performance.

    Romanian amber (rumanite) has been considered to be a separate species of fossil resin for more than a century. While earlier investigators held it to be very similar to succinite (Baltic amber), modern scholars have assigned it a distinctly different botanical origin. We have found that almost all of the constituents of the ether-soluble fractions of 13 specimens of authentic rumanite identified by gas chromatography-mass spectrometry have previously been reported in the soluble fraction of succinite, including succinic acid and its monoterpene esters. Additionally and significantly, the soluble fraction of rumanite contains a number defunctionalized compounds that do not preexist in succinite, but that are produced by pyrolysis of whole succinite or of its insoluble polymeric fraction. Simultaneous methylation pyrolysis-gas chromatography-mass spectrometry of the polymeric fraction of seven of the rumanite specimens yielded further copious amounts of dimethyl succinate, a number of diterpene resin acid methyl esters, and additional defunctionalized compounds known to be pyrolysis products of succinite. The evidence shows conclusively that the botanical origin of rumanite is not distinct from that of succinite. Rather, rumanite is a succinite that has suffered partial thermal degradation in the course of the folding of the Oligocene Kliwa sandstone formation in which it is most commonly found.

    H, C, O stable isotope ratios and the content of some heavy elements of 31 Romanian single-strength organic apple juices collected from four Transylvanian areas are discussed in this study. The aim of this study was to measure the 2H/1H, 18O/16O, 13C/12C ratios of these juices and their elemental profile and to establish a database of authentic values to be used for adulteration and authenticity testing. Our results have shown mean values of δ18O = −4.2‰ and δDδ−46.5‰, respectively, for apples from Transylvania and at the same time the mean value of δ13C = −28.2‰. The content of Cd, Pb, U, Zn, As was below the acceptable limits stipulated in US-EPA standard for drinking water. Cu and Cr limits exceeded for one single juice; Ni content for some apple juices from Maramures, Alba, and Cluj was higher than the acceptable value. PMID:22666164

    In this study, metal threads from Romanian religious embroideries and precious velvet brocades dated from 15th to 18th century were analyzed by using IBA methods (PIXE and RBS) which, in comparison to the traditional analytical techniques (XRF, EDS), allowed the detection of their structures and accurate identification of the trace elements (detection limits of few tens of ppm). PIXE results confirmed that both types of the metal threads studied - wires and strips - have layered structures being made of fine silver, refined by cupellation, and gilded most probably with pure gold, and not of Au-Ag alloy, or gilded Ag-Cu alloy or Au-Ag-Cu alloy, as resulted from the previously performed SEM-EDS analysis. Trace elements of historical interest like lead, mercury and bismuth have been also possible to be detected by PIXE. The resulting elemental maps allowed us to identify the areas from which the metal thread structure and quantitative composition could be accurately determined. RBS measurements revealed that the gilding layer is separated from the silver bulk by an interface layer resulting through atomic diffusion of silver into the gold, which lead to the conclusion that the methods used for gilding were probably either the diffusion bonding or the fire gilding. The gilding layers thicknesses were estimated by PIXE with the GUPIX software and also determined from RBS measurements.

    BACKGROUND: Human activity in wilderness areas has increased globally in recent decades, leading to increased risk of injury and illness. Wilderness medicine has developed in response to both need and interest. METHODS: The field of wilderness medicine encompasses many areas of interest. Some focus on special circumstances (such as avalanches) while others have a broader scope (such as trauma care). Several core areas of key interest within wilderness medicine are discussed in this study. RESULTS: Wilderness medicine is characterized by remote and improvised care of patients with routine or exotic illnesses or trauma, limited resources and manpower, and delayed evacuation to definitive care. Wilderness medicine is developing rapidly and draws from the breadth of medical and surgical subspecialties as well as the technical fields of mountaineering, climbing, and diving. Research, epidemiology, and evidence-based guidelines are evolving. A hallmark of this field is injury prevention and risk mitigation. The range of topics encompasses high-altitude cerebral edema, decompression sickness, snake envenomation, lightning injury, extremity trauma, and gastroenteritis. Several professional societies, academic fellowships, and training organizations offer education and resources for laypeople and health care professionals. CONCLUSIONS: The future of wilderness medicine is unfolding on multiple fronts: education, research, training, technology, communications, and environment. Although wilderness medicine research is technically difficult to perform, it is essential to deepening our understanding of the contribution of specific techniques in achieving improvements in clinical outcomes.

  18. Determinants of pathologic mineralization.

    PubMed

    Kirsch, Thorsten

    2008-01-01

    Physiologic mineralization is necessary for the formation of skeletal tissues and for their appropriate functions during adulthood. Mineralization has to be controlled and restricted to specific regions. If the mineralization process occurs in regions that normally do not mineralize, there can be severe consequences (pathologic or ectopic mineralization). Recent findings have indicated that physiologic and pathologic mineralization events are initiated by matrix vesicles, membrane-enclosed particles released from the plasma membranes of mineralization-competent cells. The understanding of how these vesicles are released from the plasma membrane and initiate the mineralization process may provide novel therapeutic strategies to prevent pathologic mineralization. In addition, other regulators (activators and inhibitors) of physiologic mineralization have been identified and characterized, and there is evidence that the same factors also contribute to the regulation of pathologic mineralization. Finally, programmed cell death (apoptosis) may be a contributor to physiologic mineralization and if occurring after tissue injury may induce pathologic mineralization and mineralization-related differentiation events in the injured and surrounding areas. This review describes how the understanding of mechanisms and factors regulating physiologic mineralization can be used to develop new therapeutic strategies to prevent pathologic or ectopic mineralization events.

    The widespread use of complementary and alternative medicine techniques, often explored by patients without discussion with their primary care physician, is seen as a request from patients for care as well as cure. In this article, we discuss the reasons for the growth of and interest in complementary and alternative medicine in an era of rapidly advancing medical technology. There is, for instance, evidence of the efficacy of supportive techniques such as group psychotherapy in improving adjustment and increasing survival time of cancer patients. We describe current and developing complementary medicine programs as well as opportunities for integration of some complementary techniques into standard medical care. PMID:9584661

    2015-11-01

    In Romania, the large majorities of the manufacturing companies consume natural resources and energy in an unsustainable manner. Over the years, the emissions of greenhouse gases have led not only to many environmental problems but also to important social and economic problems. A real solution to help the Romanian manufacturing companies to adapt to the new legislative requirements is the green manufacturing implementation. Considering the current situation, the purpose of this paper is to present a model that will integrate the green manufacturing concept at the organizational level based on the practices identified in the Romanian manufacturing companies at the operational level in the context of sustainable development.

    In Europe the characteristics, distribution and effects of recent pollution are well known, with monitoring observations existing at a continental scale. However, estimates of long-term pollution are restricted to central-western Europe, the British Isles and Scandinavia. In Eastern Europe in particular, the lack of such estimates has led to incomplete understanding of regional differences. When coupled to the insufficient knowledge of past emission sources and isotopic signatures of various ores, it is clear there are gaps in our knowledge of the history of pollution in this area. As a result, the causal relationship between humans and the environment are insufficiently explored, particularly within the Carpathian region- one with mineral wealth and a long history of human presence. Peat bogs have long been used as an archive for environmental and climatic imprints, with research using climate indicators from bogs burgeoning in recent decades, and a range of proxies for past hydrological change have been developed. The potential for utilising the geochemistry of archives such as peat bogs to resolve the input of metals from the atmosphere has long been known, and has been used to distinguish the background levels from the anthropogenic imprint. Here we present initial results from a multi-proxy study into the geochemical history of a collection of ombrotrophic peat bogs located in the Romanian section of the study region. We present elemental concentrations for a number of the base metals associated with metal mining, smelting and subsequent pollution. These data (base metal concentrations) display the first such study in the region and indicate a pollution history hitherto unseen in the records from Western Europe, with peaks in metal production over time periods during which production was thought to be low. This includes a large, likely medieval Pb peak, and extended periods of metal production in the region after the Roman occupation. These early peaks are

    The author uses the results of his own researches as well as data from specialty literature to assess the ecological state of some typical lacustrine ecosystems considered, about 50 years ago, of major importance by their functions, services and researches, for the human populations in the settlements nearby. Based on this assessment the author recommends a few criteria which can be taken into account when programs of integrated management of these coastal ecosystems are initiated. The paper focuses on the study cases regarding the following major ecosystems: 1. Razelm-Sinoie Lagoon Complex - tightly linked to the Danube River and Delta systems, 2. Taşaul Lake - interfered in the last two decades by a branch of the DanubeRiver - Black Sea Canal and 3. Techirghiol Lake - for a long time under the sea level, a hyperhaline lake with therapeutic, sapropelic mud, disturbed by huge quantities of freshwaters infiltrated from the irrigation system. At present, the state of the lacustrine ecosystems at the Romanian Black Sea Coast can be characterized, mainly, by the following aspects: · Increase in the quantities of nutrients and chemical toxicants; · Rise in the level and frequency of eutrophication and pollution phenomena; · Drastic reduction of specific diversity; · Simplification of communities' structure - biocoenosis homogeneity; · Decrease in numerical abundance and biomass of benthic populations and consequently, low biofilter power by the decrease of the filter-feeder populations; · Worsening of the qualitative and the quantitative state of the biological benthic resources; · Thriving opportunistic forms (e.g. the worms causing sediment bioturbation); · Invasion by some exotic species, with harmful, unexpected consequences; · All populations undergo quantitative fluctuations; · Decrease in the fish population and in the use values of lacustrine assets, with strong impact on the welfare of the human society.

    (MRE) was initiated in the years '60 of the past century at the Chair of Aerospace Sciences "Elie Carafoli" from the "Politehnica" University in Bucharest (PUB). Consisting of theoretical and experimental investigations in the form of computational methods and technological solutions for small size MRE-s and the concept of the test stand for these engines, the program ended in the construction of the first Romanian liquid rocket motors. Hermann Oberth and Dorin Pavel, were known from 1923, no experimental practice was yet tempted, at the time level of 1960. It was the intention of the developers at PUB to cover this gap and initiate a feasible, low-cost, demonstrative program of designing and testing experimental models of MRE. The research program was oriented towards future development of small size space carrier vehicles for scientific applications only, as an independent program with no connection to other defense programs imagined by the authorities in Bucharest, at that time. Consequently the entire financial support was assured by "Politehnica" university. computerized methods in the thermochemistry of heterogeneous combustion, for both steady and unsteady flows with chemical reactions and two phase flows. The research was gradually extended to the production of a professional CAD program for steady-state heat transfer simulations and the loading capacity analyses of the double wall, cooled thrust chamber. The resulting computer codes were run on a 360-30 IMB machine, beginning in 1968. Some of the computational methods were first exposed at the 9th International Conference on Applied Mechanics, held in Bucharest between June 23-27, 1969. hot testing of a series of storable propellant, variable thrust, variable geometry, liquid rocket motors, with a maximal thrust of 200N.

    Understanding the earthquake phenomena and their effects is an important step toward the education of population and aims to raise the awareness about the earthquake risk and possible mitigation actions. In this sense, The Romanian Educational Seismic Network project represents an efficient communication tool, allowing teaching and learning about the earthquakes and seismic wave impact through experimental practices and educational activities. The seismic network consist of nine SEP seismometers installed in high-schools from the most important seismic areas (Vrancea, Banat, Făgăraş, Dobrogea), vulnerable cities (Bucharest, Iasi) or high populated places (Cluj, Sibiu, Timisoara, Zalău) and is coordinated by the National Institute of Earth Physics from Bucharest. Once installed, the seismic network is the starting point of activities for students through an e-learning platform. Some objectives are aimed: - To train students and teachers how to make analysis and interpretation of seismological data; - To make science more interesting for students; - To improve the participation rates in physical sciences for students; - To raise awareness of geoscience as a scientific discipline for pre-university students; - To promote the installation and effective use of educational seismographs and seismic data; - To reinforce and develop relationships between participating schools and research institutes; - To create an earthquake database this will be used by students and teachers for educational purposes. Different types of practical activities using educational seismometer, designed by researchers for students, are described in educational materials and in the web platform project. Also we encourage the teachers from the participating schools to share their experiences and produce new didactic tools for the classroom. This collaborative work could illustrate the conjugated efforts of researchers and teachers for a better education and awareness of the risk culture

    In order to assure optimal care of patients with chronic illnesses, it is necessary to take into account the cultural factors that may influence health-related behaviors, health practices, and health-seeking behavior. Despite the increasing number of Romanian Roma, research regarding their beliefs and practices related to healthcare is rather poor. The aim of this paper is to present empirical evidence of specificities in the practice of healthcare among Romanian Roma patients and their caregivers. Using a qualitative exploratory descriptive design, this study is based on data gathered through three focus groups with 30 health mediators in the counties of Iasi and Cluj (Romania). We identified various barriers to access to healthcare for Roma patients: lack of financial resources and health insurance coverage, lack of cognitive resources or lack of personal hygiene, but also important cultural issues, such as the shame of being ill, family function, disclosure of disease-related information, patient's autonomy, attitudes towards illness and health practices, that should be considered in order to create a culturally sensitive environment in Romanian medical facilities:… The role of the health mediators within the context of cultural diversity is also discussed, as cultural brokers contributing to health care quality among Romanian Roma patients Bridging cultural differences may improve patient-healthcare provider relationships, but may have limited impact in reducing ethnic disparities, unless coupled with efforts of Roma communities to get involved in creating and implementing health policies.

    2007-01-01

    Although the Mesopotamian civilisation is as old as that of Egypt and might even have predated it, we know much less about Mesopotamian medicine, mainly because the cuneiform source material is less well researched. Medical healers existed from the middle of the 3rd millennium. In line with the strong theocratic state culture, healers were closely integrated with the powerful priestly fraternity, and were essentially of three main kinds: barû (seers) who were experts in divination, âshipu (exorcists), and asû (healing priests) who tended directly to the sick. All illness was accepted as sent by gods, demons and other evil spirits, either as retribution for sins or as malevolent visitations. Treatment revolved around identification of the offending supernatural power, appeasement of the angry gods, for example by offering amulets or incantations, exorcism of evil spirits, as well as a measure of empirical therapy aimed against certain recognised symptom complexes. Medical practice was rigidly codified, starting with Hammurabi's Code in the 18th century BC and persisting to the late 1st millennium BC. Works like the so-called Diagnostic Handbook, the Assyrian Herbal and Prescription Texts describe the rationale of Mesopotamian medicine, based predominantly on supernatural concepts, although rudimentary traces of empirical medicine are discernible. There is evidence that Egyptian medicine might have been influenced by Mesopotamian practices, but Greek rational medicine as it evolved in the 5th/4th centuries BC almost certainly had no significant Mesopotamian roots.

    Abstract Objective To define the practice of travel medicine, provide the basics of a comprehensive pretravel consultation for international travelers, and assist in identifying patients who might require referral to travel medicine professionals. Sources of information Guidelines and recommendations on travel medicine and travel-related illnesses by national and international travel health authorities were reviewed. MEDLINE and EMBASE searches for related literature were also performed. Main message Travel medicine is a highly dynamic specialty that focuses on pretravel preventive care. A comprehensive risk assessment for each individual traveler is essential in order to accurately evaluate traveler-, itinerary-, and destination-specific risks, and to advise on the most appropriate risk management interventions to promote health and prevent adverse health outcomes during travel. Vaccinations might also be required and should be personalized according to the individual traveler’s immunization history, travel itinerary, and the amount of time available before departure. Conclusion A traveler’s health and safety depends on a practitioner’s level of expertise in providing pretravel counseling and vaccinations, if required. Those who advise travelers are encouraged to be aware of the extent of this responsibility and to refer all high-risk travelers to travel medicine professionals whenever possible. PMID:25500599

    In a critical situation of world official medicine, we can find different alternatives therapies: natural therapy traditional and complementary, survival sometimes, of antique stiles and conditions of life. New sciences presented for them empiricism to the margin of official science. Doctors and sorcerer do the best to defeat the horrible virus that contribute to build symbols categories of sick. The alternatives put dangerously in game the scientific myth of experiment and exhume, if they got lost, antique remedy, almost preserved like cultural wreck very efficient where the medicine is impotent. Besides alternatives and complementary therapies, that are remedies not recognized conventional from official medicine, there are the homeopathic, phytotherapy, pranotherapy, nutritional therapy, the ayurveda, the yoga, ecc. Italians and internationals research show a composite picture of persons that apply that therapies. Object of this work is to understand and know the way that sick lighten their sufferings and role that have o that can assume the nurses to assist this sick. PMID:12146072

    Southern part of Romanian territory (Romanian Plain) is one of the most arid area in the country, while representing the main agricultural region with respect to cereal (wheat and maize) crops. Several local studies highlighted the increasing risk for enhanced aridity in three smaller areas in this region: Dobrogea (eastern side), South Moldova Plain (south-east) and Oltenia Plain (south-western part). A tendency for increased temperature and dry spells as well as prolonged periods with significant surface wind speed were identified in the Oltenia Plain. The main driving factors for the above-mentioned changes are both global signal of climate change and local factors. We have investigated these factors, trying to evaluate how present climate conditions would be affected if (a) the cultivated area in the Romanian Plain would be converted to natural vegetation; and (b) a more intensive agriculture would be practiced (i.e. irrigated crops). In this study, we perform a 10 years (2000-2010) simulation using regional climate model RegCM, at a horizontal resolution of 40 km, on a domain covering the entire Romanian territory, using as initial and lateral boundary conditions data from ERA-INTERIM at 0.75x0.75 deg. This larger-scale simulation is further used to provide boundary conditions for two nested experiments at 10 km, centered on a smaller area in the Romanian Plain. The simulations on the smaller domain are characterized in terms of land-use by (a) tall grass (considered as natural vegetation in the absence of crop/cultivated land) and (b) irrigated crop. The effects on the climatic conditions are evaluated with respect to precipitation, air temperature, surface wind speed (changes in spatial distribution, extremes, frequency of threshold values). Further work will assess these effects in the context of climate change scenarios, possibly providing useful information for agriculture planning.

    Complementary medicine can be described as additional approaches to care outside of mainstream medical practice but frequently based on traditional practices of nonwestern cultures. These include acupuncture, meditation, massage, diet manipulation, and many others. Recent reviews demonstrate wide and frequent use of these measures, often without concurrent discussion with the patient's physician. One estimate is that more than $13 billion is spent annually on complementary techniques in the United States alone. Many patients with cancer turn to these techniques. Care givers need to recognize this trend, learn about complementary medicine, and guide patients in their proper application when appropriate.

    Wilderness medicine encompasses prevention and treatment of illness and injury, education and training, emergency medical services, and search and rescue in the wilderness. Although traumatic injuries, including minor injuries, outnumber medical illness as the cause of morbidity in the wilderness, basic understanding of the prevention and management of injury and illness, including recognition, identification, treatment, initial management, and stabilization, is essential, in addition to the ability to facilitate evacuation of affected patients. An important theme throughout wilderness medicine is planning and preparation for the best- and worst-case scenarios, and being ready for the unexpected.

    By the year 2000, over 90% of cases of acquired immunodeficiency syndrome (AIDS) are expected in Third World countries where Western medicine is often unavailable, unaffordable, or culturally unacceptable. Thus, there is a need for greater attention to the potential role of traditional medicine and healers in the prevention and treatment of AIDS. A US-based nongovernmental organization, Green Cross Inc, is examining cross-cultural healing traditions and seeking areas of convergence between scientific bio-medicine and indigenous traditional healing systems. At a street clinic operated by Green Cross in Washington DC, both Western medicine and traditional Chinese practices such as acupuncture, herbal remedies, and meditation are offered to AIDS patients at those at risk of infection. Although the individualized nature of Chinese medicine makes it difficult to evaluate through use of Western research methods, there is anecdotal evidence that it reduces the stress, anxiety, depression, and fatigue that accompany AIDS. Health care systems in all parts of the world could benefit from the concept that illness cannot be treated in isolation from individuals and communities.

    The study's main aim is obtaining aerosols particulate elemental distribution and mapping it for some Romanian regions, in order to obtain preliminary information regarding the concentrations of aerosol particles and networking strategy versus local conditions. For this we used the mobile sampling strategy, but taking care on all local specific conditions and weather. In the summer of 1993, in July we took about 8 samples on a rather large territory of SE Romania which were analysed and mapped. The regions which showed an interesting behaviour or doubts such as Bucharest and Dobrogea were zoomed in near the same period of 1994, for comparing the new details with the global aspect previously obtained. An attempt was made to infer the minimum necessary number of stations in a future monitoring network. A mobile sampler was used, having tow polycarbonate filter posts of 8 and 0.4 μm. PIXE elemental analysis was performed on a 2.5 MV Van de Graaff accelerator, by using a proton beam. More than 15 elements were measured. Suggestive 2D and 3D representations were drawn, as well as histogram charts for the concentrations' distribution in the specific regions at the specified times. In spite of the poor samples from the qualitative point of view the experiment surprised us by the good coincidence (good agreement) with realities in terrain known by other means long time ago, and highlighted the power of PIXE methods in terms of money and time. Conclusions over the link between industry, traffic, vegetation, wether, surface waters, soil composition, power plant exhaust and so on, on the one hand, and surface concentration distribution, on the other, were drawn. But the method's weak points were also highlighted; these are weather dependencies (especially air masses movement and precipitation), local relief, microclimate and vegetation, and of course localisation of the sampling point versus the pollution sources and their regime.

    Osteopathy is originated in the 19th century in the United States. Andrew Taylor Still seek for an alternative medical system to the orthodox medicine largely empirical and advocating bloodletting, calomel, etc., all of which was resumed with terms like" heroic medicine". Osteopathy as other alternative medical practices (homeopathy, eclecticism, etc.) based on rational and metaphysical postulates as vitalism or the fact that man is a divinely ordained machine. Still's approach was essentially manual and based on manipulation of the joints. Today osteopaths challenge these dogmas and seek to agree their practice within scientific biomedical standards. Even if strong randomized clinical trials are lacking, several surveys report how osteopathy gained public notoriety. Several recent meta-analyses pinpoint the benefit of the spinal manipulative treatment and even if there is no evidence that such an approach is superior to other advocated therapies there is no evidence that these therapies are more effective than the first one. The major indications for such a treatment are cervical and low back pain, either chronic or acute. The quality of the relationship between the practitioner and patient together with the placebo effect are important components of a treatment effect. Osteopathic education is an important aspect and only higher education institutions, i.e. universities can achieve and maintain adequate standards. Materia medica and surgery represent the two major therapeutic mainstreams in medicine; osteopathy considered as manual medicine could be the third one. PMID:22034767

    We aimed to analyse the genetic diversity of Romanian wild boars and to compare it with that from other wild boar and pig populations from Europe and Asia. Partial sequencing of the mitochondrial encoded cytochrome b (MT-CYB) gene from 36 Romanian wild boars and 36 domestic pigs (Mangalitza, Bazna and Vietnamese breeds) showed that the diversity of Romanian wild boars and Mangalitza pigs is fairly reduced, and that most of the members of these two populations share a common MT-CYB haplotype. Besides, in strong contrast with the Bazna animals, Romanian wild boars and Mangalitza swine did not carry Asian variants at the MT-CYB locus. The autosomal genotyping of 18 Romanian wild boars with the Illumina Porcine SNP60 BeadChip revealed that their genetic background is fundamentally European, even though signs of a potential Near Eastern ancestry (~25%) were detectable at K = 4 (the most significant number of clusters), but not at higher K-values. Admixture analysis also showed that two wild boars are of a hybrid origin, which could be explained by the mating of feral animals with domestic pigs. Finally, a number of Romanian wild boars displayed long runs of homozygosity, an observation that is consistent with the occurrence of past population bottlenecks and the raise of inbreeding possibly due to overhunting or to the outbreak of infectious diseases.

    A study was carried out on mineral lung burden in 85 autopsy cases who died accidentally. Subjects of both sexes aged from 15 to 70 years were selected from all the autopsies performed at the Institute of Forensic Medicine in Rome. These subjects were living in an urban area and were not affected by neoplasm diseases. All selected subjects were residing in Rome at the time of their death. Information on years of legal residence in urban areas, smoking habits and occupational history were obtained by interviews with relatives. Lung parenchyma samples were obtained from the right upper lobe. The mineral particulate matter present in the tissue samples was studied by means of analytical transmission electron microscopy (ATEM) techniques: 16 mineral varieties and 22 metallic elements were identified. Smoke, age and residence seem to have influence on the lung burden.

    One of the personalities who marked in a positive way the evolution of Romanian histology was Ioan Dragoiu (1873-1941). Unfortunately, after nearly three quarters of a century after his death his name is not sufficiently known, both in Cluj (where he had the most significant part of his career), as well as in whole Romania. He was the first full professor of histology who devoted himself to the Romanian Faculty of Medicine from Cluj, where he worked from 1924 until 1941. During this period, he created a school of histology, among his disciples being Cornel Crisan (1895-1958) and Iosif Mihalca (1906-1981). The most important achievement of Dragoiu was his complete histology textbook, which was a premiere in the Romanian scientific literature. The title is "Histological Elements and Microscopic Techniques" (1931-1933). Our paper presents the opening lecture of histology, held by Dragoiu on January 19, 1925 at the Faculty of Medicine from Cluj. Although this lecture is neglected, it represents a very significant document in which Dragoiu gave arguments concerning the role of histology in the curricula of medical faculties. It also reveals his conception about the usefulness of correlating the notions of histology with those of physiology. A special part of this lecture was focused on the presentation of the majority of the most important masters of histology from the past. PMID:26743309

    Theriac was an ancient multi-ingredient preparation; originating as a cure for the bites of serpents, mad dogs and wild beasts, it later became an antidote to all known poisons. The name theriac (treacle), (Greek theriake, Latin theriaca, French thériaque) was derived from the Greek for wild beast - theriakos. The first formula was created by Mithridates Vl, King of Pontus, a skillful ruler but a monster of cruelty, who, living in such a fear of being poisoned, took a great interest in toxicology. In the 1st century AD, Nero's personal physician Andromachus improved the formula of Antidotum Mithridatium by adding flesh of vipers, which was commonly believed to be the best antidote against snakebite, and by increasing the proportion of opium. It became known as Theriac of Andromachus, and contained 64 ingredients including various minerals, herbals, poisons and animal flesh and blood, all combined with honey in the form of electuarium. Later it became the cure-all medicine which, accumulating all the simples into one form, was supposed to be a universal panacea against all diseases. In the Middle Ages this famous electuarium become a patent medicine and entered official dispensaries and pharmacopoeias. The most famous and expensive Theriac in Europe was that of Venice. It was not until the l8th century that it was excluded from medical use.

    The National Academy of Sciences Committee on Space Biology and Medicine points out that space medicine is unique among space sciences, because in addition to addressing questions of fundamental scientific interest, it must address clinical or human health and safety issues as well. Efforts to identify how microgravity affects human physiology began in earnest by the United States in 1960 with the establishment of the National Aeronautics and Space Administration (NASA's) Life Sciences program. Before the first human space missions, prediction about the physiological effects of microgravity in space ranged from extremely severe to none at all. The understanding that has developed from our experiences in space to date allows us to be guardedly optimistic about the ultimate accommodations of humans to space flight. Only by our travels into the microgravity environment of space have we begun to unravel the mysteries associated with gravity's role in shaping human physiology. Space medicine is still at its very earliest stages. Development of this field has been slow for several reasons, including the limited number of space flights, the small number of research subjects, and the competition within the life sciences community and other disciplines for flight opportunities. The physiological changes incurred during space flight may have a dramatic effect on the course of an injury or illness. These physiological changes present an exciting challenge for the field of space medicine: how to best preserve human health and safety while simultaneously deciphering the effects of microgravity on human performance. As the United States considers the future of humans in long-term space travel, it is essential that the many mysteries as to how microgravity affects human systems be addressed with vigor. Based on the current state of our knowledge, the justification is excellent indeed compelling- for NASA to develop a sophisticated capability in space medicine. Teams of physicians

    Characterizing climatic changes in the high-altitude mountain regions helps scientists and policy makers understand the effects of such changes on water resources, economic development, and the health of ecosystems. This paper proposes a change-point analysis to determine the time and magnitude of summer temperature changes in the summit areas of Romanian Carpathians between 1961 and 2007. Due to their altitude, massiveness, and position, Romanian Carpathians are an important barrier for different types of air masses between Western and Southeastern Europe. The results show that the change in summer temperatures occurred shortly after 1980. The average magnitude of this change is consistent with changes occurring in other parts of Southern Europe in the same time period although the magnitude of changes at individual weather stations may differ substantially. We aided our analysis by a statistical method based on regression models with serially correlated ARMA errors.

    For centuries children were considered "mini-adults". Together with expressing the need to educate children and putting a stop to their integration in the work field from the earliest years the 19th century also displayed a new image of the child, which clearly separates him from the adults. In this paper the authors analyze the Romanian legislation addressing juvenile delinquency in criminal temporal evolution. On the one hand the minority age limits are sought and modulation of legislative provisions according to these, and on the other hand, types of penalties for minors are discussed. The authors conclude that the approach to juvenile delinquency in the current Romanian Criminal Code is the result of a long process of reflection of the legislators on adopting a different system of sanctions for juvenile offenders and on creating special regulations concerning the prosecution, trial and enforcement of the decisions regarding them.

    In order to fulfil the European task for market survey in food irradiation the first Romanian laboratory for detection of irradiated foodstuffs was established at IRASM Irradiation Centre. In this preliminary study, a wide range of Romanian food samples (spices, vegetables and meat) gamma irradiated at IRASM have been studied using different detection methods: (1) DNA comet assay, (2) thermoluminescence (TL) and (3) electron spin resonance (ESR) for foodstuffs containing bone or cellulose. The results suggest that there is no general available detection method and there is no perfect detection method. In conclusion, in order to carry out a correct identification of radiation treatment of a food sample it is recommended to use at least two standardised detection methods.

  17. Reagan issues mineral policy

    NASA Astrophysics Data System (ADS)

    The National Materials and Minerals Program plan and report that President Reagan sent to Congress on April 5 aims to ‘decrease America's minerals vulnerability’ while reducing future dependence on potentially unstable foreign sources of minerals. These goals would be accomplished by taking inventory of federal lands to determine mineral potential; by meeting the stockpile goals set by the Strategic and Critical Material Stockpiling Act; and by establishing a business and political climate that would encourage private-sector research and development on minerals.Now that the Administration has issued its plan, the Subcommittee on Mines and Mining of the House Committee on Interior and Insular Affairs will consider the National Minerals Security Act (NMSA), which was introduced 1 year ago by subcommittee chairman Jim Santini (D-Nev.) [Eos, May 19, 1981, p. 497]. The bill calls for establishing a three-member White-House-level council to coordinate the development of a national minerals policy; amending tax laws to assist the mining industry to make capital investments to locate and produce strategic materials; and creating a revolving fund for the sale and purchase of strategic minerals. In addition, the NMSA bill would allow the secretary of the interior to make previously withdrawn public lands available for mineral development. The subcommittee will hold a hearing on the Administration's plan on May 11. Interior Secretary James Watt has been invited to testify.

    Children's books may provide an important resource of culturally appropriate emotions. This study investigates emotion displays in children's storybooks for preschoolers from Romania, Turkey, and the US in order to analyze cultural norms of emotions. We derived some hypotheses by referring to cross-cultural studies about emotion and emotion socialization. For such media analyses, the frequency rate of certain emotion displays can be seen as an indicator for the salience of the specific emotion. We expected that all children's storybooks would highlight dominantly positive emotions and that US children's storybooks would display negative powerful emotions (e.g., anger) more often and negative powerless emotions (e.g., sadness) less often than Turkish and Romanian storybooks. We also predicted that the positive and negative powerful emotion expressions would be more intense in the US storybooks compared to the other storybooks. Finally, we expected that social context (ingroup/outgroup) may affect the intensity emotion displays more in Turkish and Romanian storybooks compared to US storybooks. Illustrations in 30 popular children's storybooks (10 for each cultural group) were coded. Results mostly confirmed the hypotheses but also pointed to differences between Romanian and Turkish storybooks. Overall, the study supports the conclusion that culture-specific emotion norms are reflected in media to which young children are exposed. PMID:24987384

  1. Utilisation of Rb/Sr as proxy for mass wasting events in peat records from the Romanian Carpathians

    Mass wasting events, including landslides, avalanches and flooding related to heavy rains can have a major impact on the local environment. Due to their association to extreme precipitation and glacial retreat, their occurrence is likely to increase as the climate changes in the future. As such, understanding their causation, and predicting their future impact is of paramount importance. To make such predictions, understanding of the relationship between the climate and the mass-wasting event is key. For this to happen, we must use historical records of mass wasting and climate to tie the two together. As a result, a reliable, quick and easy method for determining these events in the sedimentological record must be developed. The Rb/Sr ratio has been suggested as one indicator of mass wasting events, particularly based on lake sediment research in glaciated terrain. Our work was initially developed upon the behaviour of the two elements during weathering, considering that Rb commonly substitutes for K in mineral lattices and Sr commonly for Ca, due to similar ionic radii. Minerals containing K are much more resistant than Ca-bearing ones, and so there is enrichment in weathering products of Ca, and therefore Sr. As a result, Sr should be enriched in weathered material, resulting in a lowering of the Rb/Sr ratio. This assumption has been proven as reliable in similar research involving aeolian deposits and lake sediments. Here we present the first Holocene record based on this proxy from a peat archive from a raised mountain bog in the Romanian Carpathians, nested at the foot of an avalanche-prone glacial cirque. Our geochemical assessments are based on complete digestion of samples, and analysis via ICP-OES, rather than based only on core scanning. Initial results look promising, with the peat core below the active layer (acrotelm) and above the minerogenically-influenced zone producing strong correlation to the estimates of the minerogenic input over the bog based

  2. Why sports medicine is not medicine.

    Sports Medicine as an apparent sub-class of medicine has developed apace over the past 30 years. Its recent trajectory has been evidenced by the emergence of specialist international research journals, standard texts, annual conferences, academic appointments and postgraduate courses. Although this field of enquiry and practice lays claim to the title 'sports medicine' this paper queries the legitimacy of that claim. Depending upon how 'sports medicine' and 'medicine' are defined, a plausible-sounding case can be made to show that sports medicine is not in fact a branch of medicine. Rather, it is sometimes closer to practices such as non-therapeutic cosmetic surgery. The argument of the paper is as follows. It begins with a brief statement concerning methodology. We then identify and subscribe to a plausible defining goal of medicine taken from a recognised authority in the field. Then two representative, authoritative, definitions of sports medicine are discussed. It is then shown that acceptance of these definitions of sports medicine generates a problem in that if they are accepted, no necessary commitment to the defining goal of medicine is present within sports medicine. It seems to follow that sports medicine is not medicine. In the final part of the paper a critical response to that conclusion is presented and rebutted. The response is one which rejects the identification of the defining goal of medicine upon which our argument rests.

  4. Evolutionary medicine.

    PubMed

    Swynghedauw, B

    2004-04-01

    Nothing in biology makes sense except in the light of evolution. Evolutionary, or darwinian, medicine takes the view that contemporary diseases result from incompatibility between the conditions under which the evolutionary pressure had modified our genetic endowment and the lifestyle and dietary habits in which we are currently living, including the enhanced lifespan, the changes in dietary habits and the lack of physical activity. An evolutionary trait express a genetic polymorphism which finally improve fitness, it needs million years to become functional. A limited genetic diversity is a necessary prerequisite for evolutionary medicine. Nevertheless, search for a genetic endowment would become nearly impossible if the human races were genetically different. From a genetic point of view, homo sapiens, is homogeneous, and the so-called human races have only a socio-economic definition. Historically, Heart Failure, HF, had an infectious origin and resulted from mechanical overload which triggered mechanoconversion by using phylogenically ancient pleiotropic pathways. Adaptation was mainly caused by negative inotropism. Recently, HF was caused by a complex remodelling caused by the trophic effects of mechanics, ischemia, senescence, diabetes and, neurohormones. The generally admitted hypothesis is that cancers were largely caused by a combination of modern reproductive and dietary lifestyles mismatched with genotypic traits, plus the longer time available for a confrontation. Such a concept is illustrated for skin and breast cancers, and also for the link between cancer risk and dietary habits.

  5. Underground mineral extraction

    NASA Technical Reports Server (NTRS)

    1980-01-01

    A method was developed for extracting underground minerals such as coal, which avoids the need for sending personnel underground and which enables the mining of steeply pitched seams of the mineral. The method includes the use of a narrow vehicle which moves underground along the mineral seam and which is connected by pipes or hoses to water pumps at the surface of the Earth. The vehicle hydraulically drills pilot holes during its entrances into the seam, and then directs sideward jets at the seam during its withdrawal from each pilot hole to comminute the mineral surrounding the pilot hole and combine it with water into a slurry, so that the slurried mineral can flow to a location where a pump raises the slurry to the surface.

    Each chapter of the 2010 edition of the U.S. Geological Survey (USGS) Mineral Commodity Summaries (MCS) includes information on events, trends, and issues for each mineral commodity as well as discussions and tabular presentations on domestic industry structure, Government programs, tariffs, 5-year salient statistics, and world production and resources. The MCS is the earliest comprehensive source of 2009 mineral production data for the world. More than 90 individual minerals and materials are covered by two-page synopses. For mineral commodities for which there is a Government stockpile, detailed information concerning the stockpile status is included in the two-page synopsis. National reserves information for most mineral commodities found in this report, including those for the United States, are derived from a variety of sources. The ideal source of such information would be comprehensive evaluations that apply the same criteria to deposits in different geographic areas and report the results by country. In the absence of such evaluations, national reserves estimates compiled by countries for selected mineral commodities are a primary source of national reserves information. Lacking national assessment information by governments, sources such as academic articles, company reports, presentations by company representatives, and trade journal articles, or a combination of these, serve as the basis for national reserves information reported in the mineral commodity sections of this publication. A national estimate may be assembled from the following: historically reported reserves information carried for years without alteration because no new information is available; historically reported reserves reduced by the amount of historical production; and company reported reserves. International minerals availability studies conducted by the U.S. Bureau of Mines (USBM), before 1996, and estimates of identified resources by an international collaborative effort (the

    Reeve, Joanne

    2010-01-01

    Patient-centredness is a core value of general practice; it is defined as the interpersonal processes that support the holistic care of individuals. To date, efforts to demonstrate their relationship to patient outcomes have been disappointing, whilst some studies suggest values may be more rhetoric than reality. Contextual issues influence the quality of patient-centred consultations, impacting on outcomes. The legitimate use of knowledge, or evidence, is a defining aspect of modern practice, and has implications for patient-centredness. Based on a critical review of the literature, on my own empirical research, and on reflections from my clinical practice, I critique current models of the use of knowledge in supporting individualised care. Evidence-Based Medicine (EBM), and its implementation within health policy as Scientific Bureaucratic Medicine (SBM), define best evidence in terms of an epistemological emphasis on scientific knowledge over clinical experience. It provides objective knowledge of disease, including quantitative estimates of the certainty of that knowledge. Whilst arguably appropriate for secondary care, involving episodic care of selected populations referred in for specialist diagnosis and treatment of disease, application to general practice can be questioned given the complex, dynamic and uncertain nature of much of the illness that is treated. I propose that general practice is better described by a model of Interpretive Medicine (IM): the critical, thoughtful, professional use of an appropriate range of knowledges in the dynamic, shared exploration and interpretation of individual illness experience, in order to support the creative capacity of individuals in maintaining their daily lives. Whilst the generation of interpreted knowledge is an essential part of daily general practice, the profession does not have an adequate framework by which this activity can be externally judged to have been done well.

  10. In search of racial types: soldiers and the anthropological mapping of the Romanian nation, 1914-44.

    PubMed

    Turda, Marius

    2013-02-01

    Turda's article explores the diverse ways in which racial research conducted on prisoners-of-war (POWs) and soldiers contributed to the emergence of anthropological narratives of national identity in Romania between 1914 and 1944. It first discusses racial typologies produced by Austrian, German, Italian and Polish anthropologists investigating POWs during the First World War, and then examines how Romanian physicians and anthropologists engaged with these typologies while refining their own scientific and nationalist agendas. An essential corollary to this development was a strong commitment to the cultivation of distinct Romanian racial types. The interwar and Second World War periods witnessed the full flowering of a Romanian race science that accommodated a racial hierarchy as the basis for national difference. Moreover, by identifying the racial types purportedly constituting the Romanian nation, anthropologists not only hoped to develop a systematic racial inventory of Romania's ethnic communities, but also to reinforce the myth of ethnogenesis, which described the Romanians as worthy of their noble European origins and legitimized their territorial claims.

    The study assessed conduct and emotional difficulties in a group of Romanian adoptees at age 11, and serves as a follow-up to assessments made when the children were 6 years old. It was found that there was a significant increase in emotional difficulties, but not conduct problems, for the Romanian sample since age 6. It was also found that emotional difficulty was significantly more prevalent at age 11 in the Romanian group than in a within-UK adoptee group. Emotional difficulties in the Romanian adoptee group were found to be significantly and strongly related to previous deprivation-specific problems (disinhibited attachment, cognitive impairment, inattention/overactivity and quasi-autism); however, the presence of such early problems did not account fully for the onset of later emotional problems. Five contrasting hypotheses concerning possible mediators for later onset of emotional difficulties for the Romanian group were examined. No links were found to duration of deprivation or other deprivation-related indices, stresses/difficulties in the postadoption family environment, or educational attainment and self-esteem. There was some evidence that emotion recognition might play a role in the emergence of these problems, but other measures of social competence and theory of mind showed no associations with the onset of emotional problems.

  12. Why Mineral Interfaces Matter

    NASA Astrophysics Data System (ADS)

    Putnis, Andrew; Putnis, Christine V.

    2015-04-01

    While it is obvious that reactions between a mineral and an aqueous solution take place at the mineral-fluid interface it is only relatively recently that high spatial resolution studies have demonstrated how the local structure of the mineral surface and the chemical composition of the fluid at the interface control both the short-range and the long-range consequences of mineral-fluid interaction. Long-range consequences of fluid-mineral interaction control element cycles in the earth, the formation of ore-deposits, the chemical composition of the oceans through weathering of rocks and hence climate changes. Although weathering is clearly related to mineral dissolution, to what extent do experimentally measured dissolution rates of minerals help to understand weathering, especially weathering mechanisms? This question is related to the short-range, local reactions that take place when a mineral, that is not stable in the fluid, begins to dissolve. In this case the fluid composition at the interface will become supersaturated with respect to a different phase or phases. This may be a different composition of the same mineral e.g. a Ca-rich feldspar dissolving in a Na-rich solution results in a fluid at the interface which may be supersaturated with respect to an Na-rich feldspar. Alternatively, the interfacial fluid could be supersaturated with respect to a different mineral e.g. an Na-rich zeolite, depending on the temperature. Numerous experiments have shown that the precipitation of a more stable phase at the mineral-fluid interface results in a coupling between the dissolution and the precipitation, and the replacement of one mineral by another. This process separates the short-range mechanisms which depend only on the composition of the interfacial solution, and the long-range consequences that depend on the composition of the residual fluid released from the reacting parent mineral. Typically such residual fluids may carry metal ions tens to hundreds of

    Recreational diving developed in the late 1940s when self-contained underwater breathing apparatus (SCUBA) first became available for civilian use. At the same time the development of the commercial airliner, in particular the jet airliner, made possible the concept of international travel for pleasure as opposed to business. Over the past 50 years the number of international tourists has increased by over 2500% from a mere 25 million in 1950 to over 700 million in 2002 (Treadwell TL. Trends in travel. In: Zuckerman JN, editor. Principles and practice of travel medicine, 2001; p. 2-6). The popularity of recreational diving has also increased over the same period from an activity experienced by a small number of individuals in the early 1950s to an activity today enjoyed by many millions. The combination of increased international travel and the means by which to enter and explore the underwater world has led to diving becoming increasingly popular as a tourist activity.

    There is a worldwide interest on geothermal, mineral and groundwater as a resource for energy, drinking water supply and therapeutic needs. The increasing trend in replacing tap water with commercial bottled mineral water for drinking purposes has become an economic, hydrogeologic and medical concern in the last decades. Several investigations have been carried out worldwide on different topics related to geothermal and mineral waters, dealing with mineral water quality assessment, origin of geothermal and mineral waters, geochemical processes that influence water chemistry and water-rock interaction In Romania, the Călimani-Gurghiu-Harghita Neogene to Quaternary volcanic chain (Eastern Carpathians) is one of the most important areas from the point of view of CO2-rich mineral waters. These mineral water springs occur within other post-volcanic phenomena like dry CO2 emissions, moffettes, bubbling pools, H2S gas emissions etc. Mineral waters from this area are used for bottling, local spas and drinking purposes for local people. The number of springs, around 2000 according to literature data, shows that there is still a significant unexploited potential for good quality drinking water in this area. Within the youngest segment of the volcanic chain, the Harghita Mts., its volcaniclastic aprons and its boundary with the Transylvanian Basin, we have carried out an investigation on 23 CO2-rich mineral water springs from a hydrogeochemical and stable isotopic point of view. The mineral waters are Ca-Mg-HCO3 to Na-Cl type. Sometimes mixing between the two types can be observed. We have detected a great influence of water-rock interaction on the stable isotopic composition of the mineral waters, shown by isotopic shifts to the heavier oxygen isotope, mixing processes between shallow and deeper aquifers and local thermal anomalies.

    Investigations of the elastic properties of the main rock-forming minerals were begun by T.V. Ryzhova and K.S. Aleksandrov over 30 years ago on the initiative of B.P. Belikov. At the time, information on the elasticity of single crystals in general, and especially of minerals, was very scanty. In the surveys of that time there was information on the elasticity of 20 or 30 minerals. These, as a rule, did not include the main rock-forming minerals; silicates were represented only by garnets, quartz, topaz, tourmaline, zircon, beryl, and staurolite, which are often found in nature in the form of large and fairly high-quality crystals. Then and even much later it was still necessary to prove a supposition which now seems obvious: The elastic properties of rocks, and hence the velocities of elastic (seismic) waves in the earth`s crust, are primarily determined by the elastic characteristics of the minerals composing these rocks. Proof of this assertion, with rare exceptions of mono-mineralic rocks (marble, quartzite, etc.) cannot be obtained without information on the elasticities of a sufficiently large number of minerals, primarily framework, layer, and chain silicates which constitute the basis of most rocks. This also served as the starting point and main problem of the undertakings of Aleksandrov, Ryzhova, and Belikov - systematic investigations of the elastic properties of minerals and then of various rocks. 108 refs., 7 tabs.

  2. Mineral resources of Antarctica

    Although the existence of mineral deposits in Antarctica is highly probable, the chances of finding them are quite small. Minerals have been found there in great variety but only as occurrences. Manganese nodules, water (as ice), geothermal energy, coal, petroleum, and natural gas are potential resources that could perhaps be exploited in the future. On the basis of known mineral occurrences in Antarctica and relationships between geologic provinces of Antarctica and those of neighboring Gondwana continents, the best discovery probability for a base-metal deposit in any part of Antarctica is in the Andean orogen; it is estimated to be 0.075 (75 chances in 1,000).

    The structure and features of surfaces of clay minerals (kaolin, montmorillonite, etc) have an important scientific and practical value. On the surface the interrelation of processes at electronic, atomic and molecular levels is realized. Availability of mineral surface to external influences opens wide scientific and technical opportunities of use of the surface phenomena, so the research of crystal-chemical and crystal-physical processes in near-surface area of clay minerals is important. After long term researches of gas-clay mineral system in physical fields the author has obtained experimental and theoretical material contributing to the creation of the surface theory of clays. A part of the researches is dedicated to studying the mechanism of crystal-chemical and crystal-physical processes in near surface area of clay mineral systems, selectivity of the surface centers to interact with gas phase molecules and adsorbophysical properties. The study of physical and chemical properties of fine clay minerals and their modification has a decisive importance for development of theory and practice of nanotechnologies: they are sorbents, membranes, ceramics and other materials with required electronic features.

    In the last year of secondary school, students studying physics and chemistry are incentivized to do a project where they must put in practice their improvement of scientific knowledge and skills, like observation of phenomena and analysis of data with scientific knowledge. In this project a group of students, tutored by the teacher, wanted to build an instrument that helps people to take their medical drugs at the right time. This instrument must have some compartments with an alarm and an LED light where the people can put their medical drugs. The instrument must be easily programed using an android program that also registers if the medicine has been taken. The students needed to simulate the hardware and software, draw the electronic system and build the final product. At the end of the school year, a public oral presentation was prepared by each group of students and presented to the school community. They are also encouraged to participate in national and international scientific shows and competitions.

    For over 30 years, the French hospital and pre-hospital medical teams are trained in disaster medicine. In fact, they are regularly confronted with the management of multiple casualties in accidents or even terrorist attacks, and more rarely to large-scale disasters. The intervention of physicians of the EMS system (SAMU-SMUR) in the field allows an original healthcare organization: in an advanced medical post, the victims are triaged according to their severity and benefit if needed of initial resuscitation. SAMU medical regulating center then organize their transport and repartition in several hospitals put on alert. To cope with a mass casualty situation, the hospital also has a specific organization, the White Plan. This plan, initiated by the director, assisted by a medico-administrative cell crisis can mobilize all the resources of the institution. Personnel are recalled and the ability of emergency units is increased. Care, less urgent, other patients are postponed. There are many plans for responding to disasters. ORSEC plans of the ministry of Interior articulate with the ORSAN plans of the ministry of Health. This complementarity allows a global mobilization of public services in disasters or exceptional medical situations.

    Leeches are hermaphroditic and hematophagous annelids. One important medical species, Hirudo medicinalis, comes from hirudiniculture of fresh water pools. Thanks to their three mandibles with some 300 teeth on their anterior muscular sucker, they easily grab to tissues and by secreting their saliva containing numerous powerful enzymes, such as hyaluronidase, collagenase and inhibitors of platelet aggregation and coagulation, like hirudin, allow blood sucking. Once they are full of blood (up to 15 g of blood), they detach themselves from their prey. Used ever since the 18th Egyptian Dynasty, leeches became famous during the first part of the XIXth century, thanks to a French physician, François Joseph Victor Broussais, known to his adversaries as the "vampire of medicine" for treating various conditions such as phlebotomy, laryngitis, ocular problems, obesity, mental disorders, etc. Overfishing, therapeutic failures and most particularly, the emergence of hygiene, brought the decline of living leeches. In 1884, an extract of leeches was obtained--hirudin and henceforth used. Nowadays, leeches are still used in microsurgery to enhance the venous circulation in finger reimplantation or skin flap transposition. Hirudin is synthesized through recombinant DNA technology and molecules such as lepirudin and desirudin are available on the market as anticoagulant.

    Defective bone mineralization has serious clinical manifestations, including deformities and fractures, but the regulation of this extracellular process is not fully understood. We have developed a mathematical model consisting of ordinary differential equations that describe collagen maturation, production and degradation of inhibitors, and mineral nucleation and growth. We examined the roles of individual processes in generating normal and abnormal mineralization patterns characterized using two outcome measures: mineralization lag time and degree of mineralization. Model parameters describing the formation of hydroxyapatite mineral on the nucleating centers most potently affected the degree of mineralization, while the parameters describing inhibitor homeostasis most effectively changed the mineralization lag time. Of interest, a parameter describing the rate of matrix maturation emerged as being capable of counter-intuitively increasing both the mineralization lag time and the degree of mineralization. We validated the accuracy of model predictions using known diseases of bone mineralization such as osteogenesis imperfecta and X-linked hypophosphatemia. The model successfully describes the highly nonlinear mineralization dynamics, which includes an initial lag phase when osteoid is present but no mineralization is evident, then fast primary mineralization, followed by secondary mineralization characterized by a continuous slow increase in bone mineral content. The developed model can potentially predict the function for a mutated protein based on the histology of pathologic bone samples from mineralization disorders of unknown etiology. PMID:26347868

    In recent years, wild birds have introduced multiple highly pathogenic avian influenza (HPAI) H5N1 virus infections in Romanian poultry. In 2005 HPAI infections were widespread among domestic poultry and anecdotal reports suggested domestic pigs may also have been exposed. We sought to examine evidence for zoonotic influenza infections among Romanian agriculture workers. Between 2009 and 2010, 363 adult participants were enrolled in a cross-sectional, seroepidemiological study. Confined animal feeding operation (CAFO) swine workers in Tulcea and small, traditional backyard farmers in Cluj-Napoca were enrolled, as well as a non-animal exposed control group from Cluj-Napoca. Enrollment sera were examined for serological evidence of previous infection with 9 avian and 3 human influenza virus strains. Serologic assays showed no evidence of previous infection with 7 low pathogenic avian influenza viruses or with HPAI H5N1. However, 33 participants (9.1%) had elevated microneutralization antibody titers against avian-like A/Hong Kong/1073/1999(H9N2), 5 with titers ≥ 1:80 whom all reported exposure to poultry. Moderate poultry exposure was significantly associated with elevated titers after controlling for the subjects' age (adjusted OR = 3.6; 95% CI, 1.1-12.1). There was no evidence that previous infection with human H3N2 or H2N2 viruses were confounding the H9N2 seroreactivity. These data suggest that H9N2 virus may have circulated in Romanian poultry and occasionally infected man. PMID:23999337

    The aim of this research was to study the accumulation of heavy metals (cadmium - Cd, lead - Pb, chromium - Cr, nickel - Ni, and copper - Cu) from water and sediments into living tissues of relevant marine species from different trophic levels of a food web, representative for shallow waters of the Romanian Black Sea Coast where the main anthropogenic impacts exist. The heavy metals concentrations were analysed by using an Atomic Absorption Spectrometer with graphite furnace, the results being further used to calculate the bioconcentration factors for a few key taxa like green and red algae, molluscs and fishes. Seven sampling sites influenced by anthropogenic pollution sources (municipal wastewater treatment plants and diffuse sources) were considered and a total of 300 samples were analysed for the period 2011-2012, this being the first unitary study for the Romanian Black Sea marine ecosystem. In 2011 and 2012 there were no significant differences between the sampling areas considering the heavy metals concentrations in water. For the sediments significant differences were observed between sampling sites for some heavy metals, namely Pb in 2011 and Pb, Cu and Cd in 2012, the highest concentrations being registered in the southern sector of the Romanian Black Sea shore, where the anthropogenic pollution sources are represented by the harbour and wastewater treatment plants. The values of the bioaccumulation factors (BCFsed) shows that algae are good accumulators for Cu>Pb>Ni>Cr>Cd, in comparison with BCFwater where the order of heavy metal accumulation was different: Cr>Ni>Pb>Cd>Cu. Molluscs have higher bioconcentration factors for Cu and Cd for sediments and for Cu and Ni for water. Rapana venosa accumulated more Cd and Cu. For fishes, Pb, Cu and Ni had the highest values in the tissues of benthonic species Mullus barbatus. In bivalve molluscs and fishes, in the majority of cases, there were not recorded exceeding mean concentrations as compared to the maximum

  12. Nutritive quality of romanian hemp varieties (Cannabis sativa L.) with special focus on oil and metal contents of seeds

    2012-01-01

    Background The study aims to determine the nutritional value of hemp seed expressed by the oil content and by the concentration of metals (Ca, Mg, K, Fe, Mn, Zn and Cd), for five varieties of monoecious and dioecious hemp seeds approved in Romania, comparative with the concentration of these metals in the soil. Results The content of oil in hempseed registers a slight decrease in the production records of 2011, losses due to drought and low levels of precipitation during the growth period. The greatest loss is found in Diana monoecious variety (26.54-20.82%) followed by Zenit varieties (27.37-22.97%), Armanca (29.27-25.32%), Silvana (28.89-25.04%) and Denise (26.96-25.30%). Siccative hemp oil has a yellowish green color and an iodine index of 140–156 g I2/100 g oil. Hemp seed are rich in mineral based Ca (144–955 mg/100 g seed), Mg (237–694 mg/100 g seed), K (463–2821 mg/100 g seed), Fe (1133-2400 mg.kg-1), Mn (63–110 mg.kg-1) and Zn (42-94 mg.kg-1). For the soil the following macroelements concentrations were determined: Ca (2100–2520 mg.kg-1), Mg (320–376 mg.kg-1) and K (232–257 mg.kg-1). Mn (156–197 mg.kg-1) and Zn (54–67 mg.kg-1) remain within normal limits for Romania. The soils in the experience area contain large amounts of Fe (19000–20430 mg.kg-1). The presence of K in large quantities determines the accumulation of large quantities of Fe in the soil. Conclusion Hempseed belonging to the five Romanian varieties are rich source of nutrients (Ca, Mg, K) and unsaturated oil easily digestible by the body, but the presence of Cd concentrations above the upper limit puts a question mark over the use of seeds in various food products. Hemp extracts easily certain metals from the soil. Significant amounts of Fe (1133–2400 mg.kg-1), Mn (63–110 mg.kg-1), Zn (42–94 mg.kg-1) and Cd (1.3-4.0 mg.kg-1) are found in hemp seeds. Hemp (Cannabis sativa L.) is included among plants suitable for phytoremediation of soil contaminated with cadmium

    Thermomagnetic and microprobe analyses are carried out and a set of magnetic characteristics are measured for 25 meteorites and 3 tektites from the collections of the Vernadsky Geological Museum of the Russian Academy of Sciences and Museum of Natural History of the North-East Interdisciplinary Science Research Institute, Far Eastern Branch of the Russian Academy of Sciences. It is found that, notwithstanding their type, all the meteorites contain the same magnetic minerals and only differ by concentrations of these minerals. Kamacite with less than 10% nickel is the main magnetic mineral in the studied samples. Pure iron, taenite, and schreibersite are less frequent; nickel, various iron spinels, Fe-Al alloys, etc., are very rare. These minerals are normally absent in the crusts of the Earth and other planets. The studied meteorites are more likely parts of the cores and lower mantles of the meteoritic parent bodies (the planets). Uniformity in the magnetic properties of the meteorites and the types of their thermomagnetic (MT) curves is violated by secondary alterations of the meteorites in the terrestrial environment. The sediments demonstrate the same monotony as the meteorites: kamacite is likely the only extraterrestrial magnetic mineral, which is abundant in sediments and associated with cosmic dust. The compositional similarity of kamacite in iron meteorites and in cosmic dust is due to their common source; the degree of fragmentation of the material of the parent body is the only difference.

    2011-01-01

    In this review, we evaluate the reports published between 1993 and 2011 that address the heavy metal accumulation in 88 medicinal plant species. We compare the safe limits for heavy metals set by governmental agencies vs. the levels at which such metals actually exist in selected medicinal plants. We also evaluate the uses and effectiveness of medicinal plants in health care, and assess the hazards of medicinal plant uses, in view of the growing worldwide use of medicinal plants. From our extensive review of the literature, we discovered that a maximum permissible level (MPL) of Pb is exceeded in 21 plant medicine species, Cd in 44 species, and Hg in 10 species. Vetiveria zizanioides a potential candidate species for the treatment of cardiovascular diseases absorb a wide range of heavy metals from metal-contaminated soils. We believe that this species is the single most impressive example of a potentially hazardous medicinal plant. Based on our review, we endorse the hypothesis that heavy metal accumulation by medicinal plants is mainly caused by extraction of soluble metals from contaminated soil, sediments and air. One continuing problem in protecting consumers of plant-based medicines is that permissible levels of all heavy metals in herbal medicine have not yet been standardized by regulating governmental entities. Moreover, there are few limit tests that exist for heavy metal content of medicinal plants, or permissible limits for essential dietary minerals, in most medicinal plants. The dearth of such limits hamstrings development of medicinal plant research and delays the release of either new or improved versions of medicinal plants or their components. In the present review, we emphasize that medicinal plants are often subjected to heavy metal contamination and that the levels at which these heavy metals sometimes occur exceeds permissible levels for some species. Therefore, collecting medicinal plants from areas that are, or may be, contaminated should be

Mint green, bottle green, and Kelly green are nice names but not of great utility in that people's physical perception of color is not always the same. In some industries, such as colored fabric manufacture, current use is to send a set of standard colors which are matched by the producer. This is similar to the use of the Munsell color charts in geology. None of these processes makes use of physical optical spectral studies. The reason is that they are difficult to obtain and interpret. For a geologist, color is very important but we rarely have the possibility to standardize the method of our color perception. One reason is that color is both a reflective and transmission phenomenon. The thickness of the sample is critical to any transmission characteristics. Hence, a field color determination is different from one made by using a petrographic microscope. Green glauconite in a hand specimen is not the same color in 30 μm thick thin section seen with a microscope using transmitted light.A second problem is that color in a spectral identification is the result of several absorption emissions,with overlapping signal, forming a complicated spectrum. Interpretation depends very greatly on the spectrum of the light source and the conditions of transmission-reflection of the sample. As a result, for this text, we will not attempt to analyze the physical aspect of green in green clays. In the discussion which follows, reference is made concerning color, to thin section microscopic perception.Very briefly, green clay minerals are green, because they contain iron. This is perhaps not a great revelation to mineralogists, but it is the key to understanding the origin and stability of green clay minerals. In fact, iron can color minerals either red or green or in various shades of orange and brown. The color most likely depends upon the relative abundance of the iron ion valence

    During 2012, the USDHHS’s Health Resources and Services Administration funded 12 accredited preventive medicine residencies to incorporate an evidence-based integrative medicine curriculum into their training programs. It also funded a national coordinating center at the American College of Preventive Medicine, known as the Integrative Medicine in Preventive Medicine Education (IMPriME) Center, to provide technical assistance to the 12 grantees. To help with this task, the IMPriME Center established a multidisciplinary steering committee, versed in integrative medicine, whose primary aim was to develop integrative medicine core competencies for incorporation into preventive medicine graduate medical education training. The competency development process was informed by central integrative medicine definitions and principles, preventive medicine’s dual role in clinical and population-based prevention, and the burgeoning evidence base of integrative medicine. The steering committee considered an interdisciplinary integrative medicine contextual framework guided by several themes related to workforce development and population health. A list of nine competencies, mapped to the six general domains of competence approved by the Accreditation Council of Graduate Medical Education, was operationalized through an iterative exercise with the 12 grantees in a process that included mapping each site’s competency and curriculum products to the core competencies. The competencies, along with central curricular components informed by grantees’ work presented elsewhere in this supplement, are outlined as a roadmap for residency programs aiming to incorporate integrative medicine content into their curricula. This set of competencies adds to the larger efforts of the IMPriME initiative to facilitate and enhance further curriculum development and implementation by not only the current grantees but other stakeholders in graduate medical education around integrative medicine

    Mineral carbonation involves silicate dissolution and carbonate precipitation, which are both natural processes that microorganisms are able to mediate in near surface environments (Ferris et al., 1994; Eq. 1). (Ca,Mg)SiO3 + 2H2CO3 + H2O → (Ca,Mg)CO3 + H2O + H4SiO4 + O2 (1) Cyanobacteria are photoautotrophs with cell surface characteristics and metabolic processes involving inorganic carbon that can induce carbonate precipitation. This occurs partly by concentrating cations within their net-negative cell envelope and through the alkalinization of their microenvironment (Thompson & Ferris, 1990). Regions with mafic and ultramafic bedrock, such as near Atlin, British Columbia, Canada, represent the best potential sources of feedstocks for mineral carbonation. The hydromagnesite playas near Atlin are a natural biogeochemical model for the carbonation of magnesium silicate minerals (Power et al., 2009). Field-based studies at Atlin and corroborating laboratory experiments demonstrate the ability of a microbial consortium dominated by filamentous cyanobacteria to induce the precipitation of carbonate minerals. Phototrophic microbes, such as cyanobacteria, have been proposed as a means for producing biodiesel and other value added products because of their efficiency as solar collectors and low requirement for valuable, cultivable land in comparison to crops (Dismukes et al., 2008). Carbonate precipitation and biomass production could be facilitated using specifically designed ponds to collect waters rich in dissolved cations (e.g., Mg2+ and Ca2+), which would allow for evapoconcentration and provide an appropriate environment for growth of cyanobacteria. Microbially mediated carbonate precipitation does not require large quantities of energy or chemicals needed for industrial systems that have been proposed for rapid carbon capture and storage via mineral carbonation (e.g., Lackner et al., 1995). Therefore, this biogeochemical approach may represent a readily

    U.S. production and sales of boron minerals and chemicals decreased during the year. Domestically, glass fiber insulation was the largest use for borates, followed by sales to distributors, textile-grade glass fibers, and borosilicate glasses. California was the only domestic source of boron minerals. The United States continued to provide essentially all of its own supply while maintaining a strong position as a source of sodium borate products and boric acid exported to foreign markets. Supplementary U.S. imports of Turkish calcium borate and calcium-sodium borate ores, borax, and boric acid, primarily for various glass uses, continued.

    The objective of this paper is to present the implementation and process evaluation of the first computer tailored program for smoking cessation among Romanian smokers. The program targeted adult smokers who declared the intention to quit smoking in the next six months. The intervention consisted of a letter tailored to several respondent characteristics: gender, cognitive variables (attitude, social influence, and self-efficacy), intention to quit smoking, goal and relapse prevention strategies (action and coping plans), and smoking behaviour. The first 80 participants entered into the program filled in a process evaluation questionnaire one month after the intervention. The results of our study confirmed that the participants had read and remembered the letter. Moreover, new for Romania, this approach was positively appreciated by the participant and the score received for the tailored letter was high. The opinions of the participants confirmed that the tailored letter provided information that was useful, trustworthy and relevant for the individual. At the same time, the participants appreciated the polite, easy to understand content of the letter. These data underlined the premises for continuing the program and for using the information and communication technologies for healthy lifestyle promotion among Romanian population. PMID:25374212

    This paper investigates winter temperature trends in the Romanian higher-altitude areas, for three types of topographies: depression, slope and summit. The main challenge is that some winter temperature trends, by comparison with the other seasons, are milder and harder to detect. We used a change-point regression model with statistically dependent errors and compared it with a standard change-point model with independent errors. Statistical theory ensures that the former model gives a more accurate trend analysis than the latter. The model with statistically dependent errors detects change-points in the mid 70s and statistically significant increasing trends both before and after the change-point. On the other hand, the model with independent errors does not detect statistically significant increasing trends after the change-points for the winter series. These general results occur for all topography types. A separate multiple regression model reveals that the winter temperature trend changes in the Romanian higher-elevations can be described by a linear additive effect of several global atmospheric circulation patterns.

    The significant rate of failure of endodontic treatment to lower incisors was attributed to poor knowledge of their endodontic morphology. As emphasized by Tinelli ME et al. (2011), the morphology of the endodontic system is strongly related to ethnicity, making possible the existence of important anatomical variations at different population groups. The present study analyzes, using radiological means, the endodontic anatomy of lower incisors extracted from a Romanian population. Five hundred seventy-five lower central and lateral incisors were radiographed and Weine's classification was used to evaluate their endodontic morphology. After processing the data, it was concluded that 81% of the studied teeth have one canal and the remaining 19% have two canals. In terms of endodontic configuration, 81% of 575 studied teeth are Weine Type I, 17% Type II, 1% Type III and 1% Type IV. Results obtained in this study are within existing international endodontic literature. Type II and IV configurations have a high degree of treatment difficulty. This requires thorough clinical and radiological examination of several incidents, possibly cone beam computed tomography (CBCT) and individualized therapeutic means to ensure treatment success. This study is the first of this magnitude in the Romanian specialty literature.

  10. Snow line analysis in the Romanian Carpathians under the influence of winter warming

    Micu, Dana; Cosmin Sandric, Ionut

    2013-04-01

    The Romanian Carpathians are subject to winter warming as statistically proved by station measurements over a 47 year period (1961-2007). Herein, the snow season is considered to last from the 1st of November to the 30th of April, when snowpack usually reaches the highest stability and thickness. This paper investigates the signals of winter temperature and precipitation change at 17 mountain station located above 1,000 m, as being considered the main triggering factors of large fluctuations in snow amount and duration in these mountains. Fewer snowfalls were recorded all over the Romanian Carpathians after the mid 80s and over large mountain areas (including the alpine ones) the frequency of positive temperature extremes became higher (e.g. winter heat waves). Late Fall snowfalls and snowpack onsets (mainly in mid elevation areas, located below 1,700 m) and particularly the shifts towards early Spring snowmelts (at all the sites) were statistically proved to explain the decline of snow cover duration across the Carpathians. However, the sensitivity of snow cover duration to recent winter warming is still blurred in the high elevation areas (above 2,000 m). The trends in winter climate variability observed in the Romanian Carpathians beyond 1,000 m altitude are fairly comparable to those estimated in other European mountain ranges from observational data (e.g. the Swiss Alps, the French Alps and the Tatra Mts.). In relation to the climate change signals derived from observational data provided by low density mountain meteorological network (of about 3.3 stations per km2 in the areas above 1,000 m), the paper analysis the spatial probability and evolution trends of snow line in each winter season across the Romanian Carpathians, based on Landsat satellite data (MSS, TM and ETM+), with sufficiently high spatial (30 to 60 m) and temporal resolutions (850 images), over the 1973-2011 period. The Landsat coverage was considered suitable enough to enable an objective

    Mountain snow cover is particularly sensitive to the observed shifts in the regime of its two determinants (air temperature and precipitation), in response to climate warming. The climate of the Romanian Carpathians became warmer particularly in winter, spring and summer, exibiting an increasing frequency of hot extremes and a decrease of freezing days. There is also an obvious trend towards a late snowpack onset in Autumn, more evident in the areas below 1,700 m, and towards an earlier Spring snowmelting, generalized across the entire region. The observed changes in the timing of snowmelt due to milder winters, are explaining most of the decline of snow cover duration in the areas below 2,000 m. Snow line, separating snow covered from snow free areas, is considered a key indicator for monitoring the changes in snow coverage under the changing climate behavior. This study aims at deriving and analysing the changes in snowline elevation (SLE) using the multi-temporal Moderate-resolution Imaging Spectrometer (MODIS) reflectance products (MYD10 and MOD10 daily and 8-day composite) and a high-resolution Digital Elevation Model (DEM) of the Romanian Carpathians (30 m). The changes in SLE were analyzed in relation to the shifts in freezing height (FH) across the Romanian Carpathians, derived from MYD11A1, MYD11A2, MOD11A1 and MOD11A2 daily and 8-day composite products, available at a spatial resolution of 1 km. Python batch scripts using Esri ArcPy were developed and applied to download, subset, reproject and mask each MODIS product. The analyses were focused on producing and using daily and 8-day composites time series from both Terra and Aqua MODIS products for a period of about 12 years, starting from 2002 up to present day. The variability of snow cover persistence was investigated at both monthly and seasonal time steps, allowing to identify the trends in SLE and FH, as well as the changes in the timing of snow melt across the region. The paper is revealing the

    Small amounts of unidentified organic compounds have only recently been inferred on Mars despite strong reasons to expect significant concentrations and decades of searching. Based on X-ray diffraction and reflectance spectroscopic analyses we show that solid oxalic acid and its most common mineral salts are stable under the pressure and ultraviolet irradiation environment of the surface of Mars, and could represent a heretofore largely overlooked reservoir of organic carbon in the martian near-surface. In addition to the delivery to Mars by carbonaceous chondrites, oxalate minerals are among the predicted breakdown products of meteoritic organic matter delivered to the martian surface, as well as any endogenic organic carbon reaching the martian surface from the interior. A reinterpretation of pyrolysis experiments from the Viking, Phoenix, and Mars Science Laboratory missions shows that all are consistent with the presence of significant concentrations of oxalate minerals. Oxalate minerals could be important in numerous martian geochemical processes, including acting as a possible nitrogen sink (as ammonium oxalate), and contributing to the formation of “organic” carbonates, methane, and hydroxyl radicals.

  14. Bioleaching of Minerals

    Bioleaching is the term used to describe the microbial dissolution of metals from minerals. The commercial bioleaching of metals, particularly those hosted in sulfide minerals, is supported by the technical disciplines of biohydrometallurgy, hydrometallurgy, pyrometallurgy, chemistry, electrochemistry, and chemical engineering. The study of the natural weathering of these same minerals, above and below ground, is also linked to the fields of geomicrobiology and biogeochemistry. Studies of abandoned and disused mines indicate that the alterations of the natural environment due to man's activities leave as remnants microbiological activity that continues the biologically mediated release of metals from the host rock (acid rock drainage; ARD). A significant fraction of the world's copper, gold and uranium is now recovered by exploiting native or introduced microbial communities. While some members of these unique communities have been extensively studied for the past 50 years, our knowledge of the composition of these communities, and the function of the individual species present remains relatively limited. Nevertheless, bioleaching represents a major strategy in mineral resource recovery whose importance will increase as ore reserves decline in quality, become more difficult to process (due to increased depth, increased need for comminution, for example), and as environmental considerations eliminate traditional physical processes such as smelting, which have served the mining industry for hundreds of years.

    Joel Hurowitz (previously at State University of New York at Stony Brook and now at the Jet Propulsion Laboratory), Nick Tosca, Scott McLennan, and Martin Schoonen (SUNY at Stony Brook) studied the production of hydrogen peroxide from freshly pulverized minerals in solution. Their experiments focused on olivine, augite, and labradorite; silicate minerals of basaltic planetary surfaces, such as the Moon and Mars, that are exposed to the intense crushing and grinding of impact cratering processes. The hydrogen peroxide produced in the experiments was enough to adequately explain the oxidizing nature of Martian regolith first determined by the Viking Landers and the results suggest, for the first time, that mechanically activated mineral surfaces may be an important part of the overall explanation for the Viking Lander biology experiment results. Hurowitz and coauthors further showed that when the pulverized minerals are heat-treated to high temperature under vacuum (to cause dehydroxylation) there is almost a 20 times increase in hydrogen peroxide production, a result which may be highly relevant to lunar dust. These careful studies demonstrate the importance of and concern about reactive dusts on planetary surfaces from two standpoints: the health of astronauts on surface maneuvers who may inadvertently breath it and the viability of possible Martian organic species to survive in such a corrosive, antiseptic surface environment.

    Since the early days, clays have been used for therapeutic purposes. Nowadays, most minerals applied as anti-inflammatory, pharmaceutics and cosmetic are the clay minerals that are used as the active ingredient or, as the excipient, in formulations. Although their large use, few information is available in literature on the content of the radionuclide concentrations of uranium and thorium natural series and 40K in these clay minerals. The objective of this work is to determine the concentrations of 238U, 232Th, 226Ra, 228Ra, 210Pb and 40K in commercial samples of clay minerals used for pharmaceutical or cosmetic purposes. Two kinds of clays samples were obtained in pharmacies, named green clay and white clay. Measurement for the determination of 238U and 232Th activity concentration was made by alpha spectrometry and gamma spectrometry was used for 226Ra, 228Ra, 210Pb and 40K determination. Some physical-chemical parameters were also determined as organic carbon and pH. The average activity concentration obtained was 906±340 Bq kg-1 for 40K, 40±9 Bq kg-1 for 226Ra, 75±9 Bq kg-1 for 228Ra, 197±38 Bq kg-1 for 210Pb, 51±26 Bq kg-1 for 238U and 55±24 Bq kg-1 for 232Th, considering both kinds of clay.

    The diversity and distribution of Earth's minerals through deep time reflects key events in our planet's crustal evolution. Studies in mineral ecology exploit mineralogical databases to document diversity-distribution relationships of minerals, which reveal that all carbon-bearing minerals, as well as subsets containing C with O, H, Ca, or Na, conform to Large Number of Rare Events (LNRE) distributions. LNRE models facilitate prediction of total mineral diversity, and thus point to minerals that exist on Earth but have not yet been discovered and described. Our model predicts that at least 548 C minerals exist on Earth today, indicating that at least 145 carbon-bearing mineral species have yet to be discovered. Furthermore, by analyzing subsets of the most common additional elements in carbon-bearing minerals (i.e., 378 C + O species; 282 C + H species; 133 C + Ca species; and 100 C + Na species), we predict that 129 of these missing carbon minerals contain oxygen, 118 contain hydrogen, 52 contain calcium, and more than 60 contain sodium. The majority of these as yet undescribed minerals are predicted to be hydrous carbonates, many of which may have been overlooked because they are colorless, poorly crystalized, and/or water-soluble. We propose the identities of plausible as yet undescribed carbon minerals, as well as search strategies for their discovery. Some of these minerals will be natural examples of known synthetic compounds, including carbides such as calcium carbide (CaC2), crystalline hydrocarbons such as pyrene (C16H10), and numerous oxalates, anhydrous carbonates, and hydrous carbonates. Many other missing carbon minerals will be isomorphs of known carbon minerals, notably of the more than 100 different hydrous carbonate structures. An understanding of Earth's "missing" minerals provides a more complete picture of geochemical processes that influence crustal evolution.

    Background In Romania (latitude 48°15’N to 43°40’N), vitamin D supplementation is common practice mostly in infants 0-1 year old. No published information is available regarding epidemiological data on vitamin D status in the Romanian population for a wide age range and geographical territory. In this context, we aimed to evaluate the seasonal and age variation of vitamin D status in a large Romanian population. Methods 6631 individuals from across Romania had performed 7544 vitamin D assessments (2012-2014) in a chain of private laboratories. Vitamin D (25-hydroxyvitamin D2 and 25-hydroxyvitamin D3) was measured using High Performance Liquid Chromatography. Vitamin D levels were classified as severe deficiency<10ng/mL, deficiency 10-20ng/mL, insufficiency 21-29ng/mL, sufficiency≥30ng/mL and potentially harmful>100ng/ml. Results Male to female ratio was 1:2.9. Age ranged from 0 to 85 years. Mean vitamin D levels increased from April (26.3ng/ml) to September (35.6ng/ml) and decreased from October (33.5ng/ml) to March (24.4 ng/ml). Overall 40% had sufficient vitamin D, while the rest were insufficient 33%, deficient 22%, severely deficient 4% and 1% potentially harmful (of them 81% under 1 year old). Males compared to females showed higher percentages of sufficiency (47% vs. 38%). Children 0- 2 years presented the highest percentage of vitamin D sufficiency (77%). Lowest percentages (21%) of sufficiency were in people 80-84 years. Conclusion In Romania, suboptimal vitamin D levels are common (59%), especially in older age, wintertime and in women. Vitamin D supplementation would be most warranted from January to April in the Romanian population. 25-hydroxyvitamin D levels>100ng/ml were relatively prevalent in children 0-1 year old (17.3%). This was attributed to supplementation errors and the fact that high-risk individuals were more likely to visit for medical check-up. Nonetheless, it stresses the need to increase awareness of the importance of preventing

    Timing and extent of glaciations in the Carpathian mountains are still controversely discussed, mostly due to the lack of well dated geomorphological and geochronological studies. We present the preliminary results of geomorphological and sedimentological analyses of glacial and lacustrine deposits in Bistricioara Valley located in the Rodna Mountains (Northern Romanian Carpathians). Most of the glacial deposits in the Romanian Carpathians, such as moraines, typically occur above 1600 m a.s.l. marking the maximum lowering of past glaciations. Most of the glacial lakes occur between 1800 and 2000 m a.s.l. Field surveys included mapping of moraines and erratic boulders using detailed topographical maps and aerial photos. A Digital Elevation Model (DEM) was derived using GIS (ArcMap 10.1) from 1:25000 topographic maps, which was further completed by field survey data. The resulting geomorphological map shows a series of moraines, which indicate the occurrence of several glacial phases in the study area. Sediment samples were collected from a peat bog (1630 m a.s.l.) dammed by a large lateral moraine within Bistricioara Mare, one of the largest glacial cirques in the Romanian Carpathians. A Russian corer was used to extract the sediment profile from the peat bog (approx. 5 m long sediment core). A X-ray computed tomography (CT) system was employed for the study of sedimentary and deformation structures and X-ray fluorescence spectroscopy (XRF) for multi-element analysis at high resolution. Glacial deposits from the lateral moraine in front of the peat bog were also sampled, as well as from the frontal moraines, upstream and downstream of the peat bog. This set of samples from multiple archives allows to link and merge the chronologies and the paleoenvironmental records of glacial deposits and lake sediments. Moreover, we employed cosmogenic nuclide dating for the reconstruction of glacial stages and their paleoclimatic implications during deglaciation in this area of

  15. Mineral bridges in nacre.

    PubMed

    Checa, Antonio G; Cartwright, Julyan H E; Willinger, Marc-Georg

    2011-12-01

    We confirm with high-resolution techniques the existence of mineral bridges between superposed nacre tablets. In the towered nacre of both gastropods and the cephalopod Nautilus there are large bridges aligned along the tower axes, corresponding to gaps (150-200nm) in the interlamellar membranes. Gaps are produced by the interaction of the nascent tablets with a surface membrane that covers the nacre compartment. In the terraced nacre of bivalves bridges associated with elongated gaps in the interlamellar membrane (>100nm) have mainly been found at or close to the edges of superposed parental tablets. To explain this placement, we hypothesize that the interlamellar membrane breaks due to differences in osmotic pressure across it when the interlamellar space below becomes reduced at an advanced stage of calcification. In no cases are the minor connections between superimposed tablets (<60nm), earlier reported to be mineral bridges, found to be such.

    2009-09-15

    A review of literature published in 2008 and early 2009 on research related to the production of acid mine drainage and/or in the dissolution of minerals as a result of mining, with special emphasis on the effects of these phenomena on the water quality in the surrounding environment, is presented. This review is divided into six sections: 1) Site Characterization and Assessment, 2) Protection, Prevention, and Restoration, 3) Toxicity Assessment, 4) Environmental Fate and Transport, 5) Biological Characterization, and 6) Treatment Technologies. Because there is much overlap in research areas associated with minerals and mine drainage, many papers presented in this review can be classified into more than one category, and the six sections should not be regarded as being mutually-exclusive, nor should they be thought of as being all-inclusive.

  17. Automated georeference of the 1: 20,000 Romanian maps under Lambert-Cholesky (1916-1959) projection system

    2009-04-01

    Before the 1918 Union, the Romanian territories were subject of several dominations, for which reason the cartographic data base for each Romanian province was different from an area to another. Starting from the second half of the 19th century, Valachia, Moldavia and Dobrogea (Dacia Pontica or Scitia Minor) field mapping was made, implicitly cartographic representations, different as structure. The projection systems used, the chosen geoid, the nomenclature and the distribution of the map pages were not uniform. For an example, the Bessel ellipsoid and the Cassini cross cylindrical projection were used especially to the eastern side of the Zimnicea central meridian (23 degree east from Paris), while to its western side the Bonne conic equivalent projection was used, as defined on the Clarke ellipsoid (Năstase, 1975, pages 86-87). In the other Romanian provinces, such as Transylvania, Romanian Banat, Bessarabia (Moldavia Republic) and Southern Bucovina, the major part of the cartographic products (surface contour maps) were made as polyhedral projections. During the World War I, when artillery was a redoubtable weapon a necessary idea was born to articulate an unitary cartographic projection concerning the entire Romanian territory, which should respond to the principle of conformity. Between 1916-1917, pursuant to the above argumented measure, a new datum/location surface, a new projection system and a new nomenclature were introduced. The Lambert projection system was used as modified by the French land surveyor, the mathematician and officer Andre Louis Cholensky. He was born in 1875 in Mont Guyon and passed away on the battle field in Northern France in the month of August 1918. During September 1916 up to February 1918, following the Franco-Romanian military convention, he was a Commander of the Geographic Department of the Romanian Army (Brezinsky-Gross-Cholensky, 1996). The calculations for passing from the various projections (as previously mentioned

  18. Individualized medicine, health medicine, and constitutional theory in Chinese medicine.

    PubMed

    Wang, Qi

    2012-03-01

    The patterns of modern science and changes in the medical model can result in the transformation of the current state of individualized and health medicines into being the primary trend in medical development. Chinese and Western medical systems are dissimilar in terms of value orientations, thinking style, and research directions because of their different historical and cultural backgrounds. Individualized treatment in modern medicine is mainly established based on individual genome information and the differences in mononucleotide polymorphisms. However, such treatment method is expensive, creates an uncertain genetic marker, and leads to different result interpretations, among other problems. The Chinese constitutional theory developed in the 1970s expresses the principle behind Chinese health medicine and individual treatment and provides the corresponding methods. The Chinese constitutional theory divides the constitution of the Chinese population into nine categories based on established classification criteria. It promotes the study of the relationship of each constitution to diseases and Chinese medicine preparation toward adjusting the constitution and preventing diseases. The theory also provides methods and tools for individualized treatment. Constitution identification shows the direction and provides the core technology for the evaluation of the health status. By combining the developments in modern biotechnology, new diagnostic techniques and treatment models of constitution-differentiation, disease-differentiation, and syndrome-differentiation can be established for the development of individualized Chinese medicine treatment and health medicine for the international medical community.

    Since the early days, clays have been used for therapeutic purposes. Nowadays, most minerals applied as anti-inflammatory, pharmaceutics and cosmetic are the clay minerals that are used as the active ingredient or, as the excipient, in formulations. Although their large use, few information is available in literature on the content of the radionuclide concentrations of uranium and thorium natural series and {sup 40}K in these clay minerals.The objective of this work is to determine the concentrations of {sup 238}U, {sup 232}Th, {sup 226}Ra, {sup 228}Ra, {sup 210}Pb and {sup 40}K in commercial samples of clay minerals used for pharmaceutical or cosmetic purposes. Two kinds of clays samples were obtained in pharmacies, named green clay and white clay.Measurement for the determination of {sup 238}U and {sup 232}Th activity concentration was made by alpha spectrometry and gamma spectrometry was used for {sup 226}Ra, {sup 228}Ra, {sup 210}Pb and {sup 40}K determination. Some physical-chemical parameters were also determined as organic carbon and pH. The average activity concentration obtained was 906{+-}340 Bq kg{sup -1} for {sup 40}K, 40{+-}9 Bq kg{sup -1} for {sup 226}Ra, 75{+-}9 Bq kg{sup -1} for {sup 228}Ra, 197{+-}38 Bq kg{sup -1} for {sup 210}Pb, 51{+-}26 Bq kg{sup -1} for {sup 238}U and 55{+-}24 Bq kg{sup -1} for {sup 232}Th, considering both kinds of clay.

It analyzes 1) the articulation of medical practices, knowledge, and institutions within specific modes of production and social formations; 2) the dual functions of medicine within capitalist relations of production; 3) the reproduction of power within medicine; and 4) the meaning of capitalist, socialist, and communist medicine. The political practice derived from these analyses is also elaborated.

  1. Salton sea minerals

    NASA Astrophysics Data System (ADS)

    Bell, Peter M.

    The long-held notion that precious metals, minerals, and other useful substances can be extracted from natural waters is starting to become realized at several locations of geothermal brines. In a recent study by A. Maimoni of the Lawrence Livermore National Laboratory it was determined that there is a high potential for minerals recovery from the hot brines of a 1000-MWe geothermal power station at the Salton Sea geothermal field in southern California. The study estimated that the revenue from the minerals could substantially exceed that from the power station (Geothermics, 11, 239-258, 1982).According to the study, ‘A 1000-MWe power plant could recover 14-31% of the U.S. demand for manganese.’ In the example of lithium production, such a geothermal plant could produce 5-10 times the annual world output of lithium. Large quantities of lead and zinc could be extracted, as well as significant amounts of gold, platinum, and silver. The chemical composition of the brines is incredibly complex, however, for reasons not currently understood.

  2. Clay Mineral Preferred Orientation

    NASA Astrophysics Data System (ADS)

    Day-Stirrat, R. J.

    2014-12-01

    Anisotropy of the orientation of clay minerals, often referred to as texture, may be unique to sediments' deposition, composition, deformation or diagenetic history. The literature is rich with studies that include preferred orientation generation in fault gouge, low-grade metamorphic rocks, sediments with variable clay content and during the smectite-to-illite transformation. Untangling the interplay between many competing factors in any one geologic situation has proven a significant challenge over many years. Understanding how, where and when clay minerals develop a preferred orientation has significant implications for permeability anisotropy in shallow burial, the way mechanical properties are projected from shallower to deeper settings in basin modeling packages and the way velocity anisotropy is accounted for in seismic data processing. The assessment of the anisotropic properties of fine-grained siliciclastic rocks is gaining significant momentum in rock physics research. Therefore, a fundamental understanding of how clay minerals develop a preferred orientation in space and time is crucial to the understanding of anisotropy of physical properties. The current study brings together a wealth of data that may be used in a predictive sense to account for fabric anisotropy that may impact any number of rock properties.

    2013-01-01

    Background: The levels of 5 minerals namely; lead, arsenic, mercury, cadmium, and aluminum were assessed in 10 medicinal plants sampled from 5 different geographical locations to determine the effect of location on the plants’ mineral content. Materials and Methods: Atomic absorption spectrophotometry (wet digestion) was used for the analyzes, and content of the minerals per sample was expressed as μg/g. The levels of minerals were compared to their limit specification for herbs and daily total intake of these minerals. A two-way analysis of variance, which tends to look at the effect of the location and the medicinal plant itself on the plants mineral content, was used in the statistical analysis. Results: Lead (Pb) was present in all plant species examined, except Ocimum gratissimum. One plant exceeded the maximum safety limit for lead. Cadmium was also detected in some of the medicinal plant species (44%) whilst majority were below the detection limit (0.002) representing 56%. 40% of the plant species exceeded the limit for cadmium. Mercury and arsenic in all the plant species were below the detection limit (0.001). Significant variation existed in mineral content for the various locations (P ≤ 0.05). Conclusion: The findings generally suggest the variation in mineral levels for the various locations. Thus, our study has shown that same species of medicinal plants, growing in different environments, accumulates different levels of heavy metals. PMID:23798884

    In the present study a simple and highly sensitive RP-HPLC method has been established for simultaneous determination of chlorogenic acid, caffeic acid, vanillic acid and caffeine in coffee samples. The method has been applied to eight different coffees available on the Romanian market which were previously analysed concerning the total polyphenols content and antioxidant capacity. Reduction of the DPPH radical was used to determine the antioxidant capacity of the coffee extracts while the total polyphenols content was determined by spectrophotometry (Folin Ciocalteu's method). The total polyphenols content ranged from 1.98 g GAE/100 g to 4.19 g GAE/100 g while the caffeine content ranged from 1.89 g/100 g to 3.05 g/100 g. A large variability was observed in chlorogenic acid content of the investigated coffee samples which ranged between 0.6 and 2.32 g/100 g.

    In this study we have made a quick review of some Romanian cosmetic products (shampoo, conditioner, face wash) in order to determine the formaldehyde content as well as other substances called "formaldehyde releasers". The process was performed based on solid-phase microextraction (SPME) followed by gas chromatography/mass spectrometry technique. Prior to SPME extraction we used a derivation step of formaldehyde using pentafluorophenyl hydrazine. The obtained product was adsorbed on SPME devices, then injected and desorbed into the GC/MS injection port. The concentration of formaldehyde (as derived compound) was calculated using calibration curve, having a regression coefficient of 0.9938. The performance parameters of the method were calculated using samples of standard concentration. The method proved to be sensitive, having a quantification limit (LOQ) of 0.15 μg/g.

    Vulnerability of participants in research and the provision of special protections for vulnerable research participants are key concepts in research ethics. Despite international consensus requiring special protections for vulnerable research participants, both the concept of vulnerability and the nature and adequacy of strategies to reduce vulnerability remain vague and, consequently, are subject to varying interpretations. We report on observations of the challenges faced in understanding this key concept by 20 Russian and Romanian trainees participating in a one-year M.A. training program in research ethics from 2000 through 2011. We describe how trainees’ understanding of and appreciation for the need for special protections of vulnerable research participants was nurtured.

    Smoking during pregnancy is causally associated with reduced birth weight and is strongly related to preterm birth. Smoking cessation in early pregnancy seems to reduce these risks, although the research evidence is limited. In a sample of Romanian women, differences in birth outcomes were assessed between non-smokers and women who continued to smoke during pregnancy and non-smokers and women who stopped smok- ing when they found out about the pregnancy. Pregnant women were recruited in two urban clinics (N= 474). A baseline questionnaire collected information on their smoking status, depressive symptoms, stress, demographics, and other characteristics at recruitment. The women reported the newborn weight and birth term by phone in the first weeks following birth. Descriptive statistics and multivariate regressions were used to ana- lyze the relationship between smoking status during pregnancy and birth outcomes. Over 61% (N = 290) women were non-smokers, 15% (N= 72) smoked during pregnancy, and 24% (N= 112) quit smoking when they found out about the pregnancy. Compared to non-smokers, continuous smokers delivered babies 165 grams lighter (95% CI -313, -17). Women who stopped smoking when they ascertained the pregnancy had higher odds of delivering a newborn who was small for gestational age compared to non-smokers (OR= 2.16, 95% CI 1.05, 4.43). Elevated maternal stress was associated with reduced birth weight (-113 grams, 95% CI -213, -11), and higher odds of a preterm birth (OR=2.8, 95% CI 1.17, 6.76). In a predominantly urban sample of Romanian women, continuous maternal smoking during pregnancy was a risk factor for restricted foetal growth. Smoking cessation when the pregnancy was ascertained did not seem to reduce this risk. Smoking prevention efforts should therefore begin before pregnancy and should integrate psychological components, addressing maternal stress in particular.

    The transport of Dangerous Goods-Class no.7 Radioactive Material (RAM), is an important part of the Romanian Radioactive Material Management. The overall aim of this activity is for enhancing operational safety and security measures during the transport of the radioactive materials, in order to ensure the protection of the people and the environment. The paper will present an overall of the safety and security measures recommended and implemented during transportation of RAM in Romania. Some aspects on the potential threat environment will be also approached with special referring to the low level radioactive material (waste) and NORM transportation either by road or by rail. A special attention is given to the assessment and evaluation of the possible radiological consequences due to RAM transportation. The paper is a part of the IAEA's Vienna Scientific Research Contract on the State Management of Nuclear Security Regime (Framework) concluded with the Institute for Nuclear Research, Romania, where the author is the CSI (Chief Scientific Investigator). The transport of RAM in Romania is a very sensible and complex problem taking into consideration the importance and the need of the security and safety for such activities. The Romanian Nuclear Regulatory Body set up strictly regulation and procedures according to the Recommendation of the IAEA Vienna and other international organizations. There were implemented the adequate regulation and procedures in order to keep the environmental impacts and the radiological consequences at the lower possible level and to assure the effectiveness of state nuclear security regime due to possible malicious acts in carrying out these activities including transport and the disposal site at the acceptable international levels. The levels of the estimated doses and risk expectation values for transport and disposal are within the acceptable limits provided by national and international regulations and recommendations but can increase

    The present study focuses on the alkaline phosphatase (ALP) mediated formation of apatitic minerals on porous silk fibroin protein (SFP) scaffolds. Porous SFP scaffolds impregnated with different concentrations of ALP are homogeneously mineralized under physiological conditions. The mineral structure is apatite while the structures differ as a function of the ALP concentration. Cellular adhesion, proliferation, and colonization of osteogenic MC3T3 cells improve on the mineralized SFP scaffolds. These findings suggest a simple process to generate mineralized scaffolds that can be used to enhanced bone tissue engineering-related utility. PMID:24610728

    The authors focus on water resources and the use of mineral waters in human nutrition, especially in the different stages of life, in physical activity and in the presence of some morbid conditions. Mineral water is characterized by its purity at source, its content in minerals, trace elements and other constituents, its conservation and its healing properties recognized by the Ministry of Health after clinical and pharmacological trials. Based on total salt content in grams after evaporation of 1l mineral water dried at 180 degrees C (dry residues), mineral waters can be classified as: waters with a very low mineral content, waters low in mineral content, waters with a medium mineral content, and strongly mineralized waters. Based on ion composition mineral waters can be classified as: bicarbonate waters, sulfate waters, sodium chloride or saltwater, sulfuric waters. Based on biological activity mineral waters can be classified as: diuretic waters, cathartic waters, waters with antiphlogistic properties. Instructions for use, doses, and current regulations are included.

    Electron microprobe mineral analysis guide is a compilation of X-ray tables and spectra recorded from various mineral matrices. Spectra were obtained using electron microprobe, equipped with LiF geared, curved crystal X-ray spectrometers, utilizing typical analytical operating conditions: 15 Kv acceleration potential, 0.02 microampere sample current as measured on a clinopyroxene standard (CP19). Tables and spectra are presented for the majority of elements, fluorine through uranium, occurring in mineral samples from lunar, meteoritic and terrestrial sources. Tables for each element contain relevant analytical information, i.e., analyzing crystal, X-ray peak, background and relative intensity information, X-ray interferences and a section containing notes on the measurement. Originally intended to cover silicates and oxide minerals the tables and spectra have been expanded to cover other mineral phases. Electron microprobe mineral analysis guide is intended as a spectral base to which additional spectra can be added as the analyst encounters new mineral matrices.

    Recent scientific studies have proven the importance of trace elements on human health. The main food supplies are plants and animals, which are significant sources of these minerals. Studies on determining mineral compositions of herbs, spices and some other crops have increased all over the world. Published works revealed that spices, herbs and medicinal plants should be consumed to obtain beneficial trace elements. Selenium (Se), one of the most vital trace elements, has a significant role in human diet acting as a preventative agent against some serious illnesses. Despite numerous scientific works on mineral compositions of medicinal and aromatic plants, investigations of selenium content in these foods could not be successfully studied until recently due to the lack of suitable analytical methods for selenium analysis. Thus, publications on selenium concentrations of foods are recent. In this regard, selenium contents of some medicinal and aromatic plants commonly used as spices, herbal teas and traditional medicines in Turkey were studied in the present research. Selenium contents of the most used parts of these plants were analyzed by ICP-OES (Varian Vista-Pro, Australia). Of the analyzed 26 medicinal and aromatic plants, the highest Se concentration (1133 microg kg-1) was found in sweet basil (Ocimum basilicum L.) and the lowest in sumac (Rhus coriaria L.) fruits (11 microg kg(-1)).

    A NIOSH analysis showed that at age 50 approximately 90% of coal miners have a hearing impairment, yet noise included hearing loss is 100% preventable. The article discusses requirements of the MSHA regulations, 30 CFR Part 62 - occupational noise exposure (2000) and a 2008-MSHA document describing technologically achievable and promising controls for several types of mining machinery. Hearing protection is still required for exposure to greater than 90 dBA. These are now commercially available ways to determine how much attenuation an individual gets from a given hearing protector, known as 'fit testing'. 3 refs., 1 fig., 1 tab., 1 photo.

    In recent years there has been a notable increase in the consumption of medicinal plants in Spanish society. This might be due to the fact that in some cases they have shown themselves to be efficient in treating certain pathologies and to the erroneous perception that these products are innocuous. Medicinal plants behave as authentic medicines since the chemical substances of which they are formed can have a biological activity in humans. For this reason, their joint administration with "conventional medicines" can produce variations in the magnitude of the effect. This type of interaction, just like those produced between two or more medicines, can produce pharmacokinetic mechanisms if they affect the processes of absorption, distribution, metabolism and excretion, or pharmacodynamic mechanisms if they affect the result of the pharmacological action. In the medical literature there are few articles and notifications of cases concerning the adverse effects and interactions that affect medicinal plants, which probably reflects an under-notification of these phenomena. If we add to this the lack of experimental data and controlled studies, perception of their prevalence is difficult or nearly impossible. This article sets out, in an order that will be explained later, the findings of an exhaustive review of the medical literature with the aim of making its existence known to the reader, without going into other considerations, such as the degree of evidence for example, which will be the subject of forthcoming articles.

    New Mexico was the largest producer of uranium in the western world during 1960s and 1970s. Investigators at the University of New Mexico School of Medicine`s Epidemiology and Cancer Control Program have been conducting epidemiological studies on uranium miners over the past 2 decades. Currently, this cohort includes more than 3600 men who had completed at least 1 y of underground work experience in New Mexico by December 31, 1976. These miners, who are now in their 5th through 7th decades, the age when lung cancer incidence is highest, are at high risk for developing this disease because they were exposed to high levels of radon progeny in the mines, and they also smoked tobacco. However, not all people comparably exposed develop lung cancer; in fact, the lifetime risk of lung cancer for the smoking uranium miners has been projected by epidemiological analyses to be no higher than 50%. Therefore, the identification of gene alterations in bronchial epithelium would be a valuable tool to ascertain which miners are at greatest risk for lung cancer. The underlying significance of the current effort confirms the hypothesis that chronic exposure to high concentrations of {alpha}-particles and tobacco smoke produces genetically altered lung epithelial cells throughout the respiratory tract of some susceptible individuals before they develop clinical disease.

    The Eastern European Grey cattle are regarded as the direct descendants of the aurochs (Bos taurus primigenius). Nowadays in Romania, less than 100 Grey animals are being reared and included in the national gene reserve. We examined the genetic diversity among Romanian Grey, Brown, Spotted and Black and White cattle breeds, with a particular focus on Romanian Grey through the use of (i) 11 bovine specific microsatellite markers on 83 animals and (ii) 638 bp length of mitochondrial DNA (mtDNA) D-loop region sequence data from a total of 81 animals. Both microsatellite and mtDNA analysis revealed a high level of genetic variation in the studied breeds. In Romanian Grey a total of 100 alleles were found, the mean number of observed alleles per locus was 9.091; the average observed heterozygosity was 0.940; the Wright’s fixation index (FIS) was negative (-0.189) and indicates that there is no inbreeding and no selection pressure. MtDNA analysis revealed 52 haplotypes with 67 variable sites among the Romanian cattle breeds without any insertion or deletion. Haplotype diversity was 0.980 ± 0.007 and ranged from 0.883 ± 0.056 (Brown) to 0.990 ± 0.028 (Spotted and Black and White). The highest genetic variability of the mtDNA was recorded in the Grey breed, where 18 haplotypes were identified. The most frequent mtDNA D-loop region belonged to T3 haplogroup (80.247%), which was found across all studied breeds, while T2 haplotypes (16.049%) was only found in Grey, Spotted and Black and White genotypes. The T1 haplotypes (3.704%) were found in the Grey and Spotted. The current results contribute to the general knowledge on genetic diversity found in Eastern European cattle breeds and could prove a valuable tool for the conservation efforts of animal genetic resources (FAnGR).

    To evaluate the pattern of Romanian population from a mitochondrial perspective and to establish an appropriate mtDNA forensic database, we generated a high-quality mtDNA control region dataset from 407 Romanian subjects belonging to four major historical regions: Moldavia, Transylvania, Wallachia and Dobruja. The entire control region (CR) was analyzed by Sanger-type sequencing assays and the resulting 306 different haplotypes were classified into haplogroups according to the most updated mtDNA phylogeny. The Romanian gene pool is mainly composed of West Eurasian lineages H (31.7%), U (12.8%), J (10.8%), R (10.1%), T (9.1%), N (8.1%), HV (5.4%),K (3.7%), HV0 (4.2%), with exceptions of East Asian haplogroup M (3.4%) and African haplogroup L (0.7%). The pattern of mtDNA variation observed in this study indicates that the mitochondrial DNA pool is geographically homogeneous across Romania and that the haplogroup composition reveals signals of admixture of populations of different origin. The PCA scatterplot supported this scenario, with Romania located in southeastern Europe area, close to Bulgaria and Hungary, and as a borderland with respect to east Mediterranean and other eastern European countries. High haplotype diversity (0.993) and nucleotide diversity indices (0.00838±0.00426), together with low random match probability (0.0087) suggest the usefulness of this control region dataset as a forensic database in routine forensic mtDNA analysis and in the investigation of maternal genetic lineages in the Romanian population.

    Milk and dairy products are considered the main sources of saturated fatty acids, which are a valuable source of nutrients in the human diet. Fat composition can be adjusted through guided nutrition of dairy animals but also through selective breeding. Recently, a dinucleotide substitution located in the exon 8 of the gene coding for acyl CoA: diacylglycerol acyltransferase 1 (DGAT1), that alters the amino acid sequence from a lysine to an alanine (p.Lys232Ala) in the mature protein, was shown to have a strong effect on milk fat content in some cattle breeds. Therefore, the objectives of this work were to study the occurrence of the DGAT1 p.Lys232Ala polymorphism in Romanian Holstein cattle and Romanian Buffalo breeds and to further investigate its possible influence on fat percentage and fatty acid profiles. The results obtained in this study show that in Romanian Holstein cattle the K allele is associated with increased fat percentage and higher levels of C16:0 and C18:0 fatty acids. The ratio of saturated fatty acids versus unsaturated fatty acids (SFA/UFA) was also higher in KK homozygous individuals, whereas the fractions of C14:0, unsaturated C18 decreased. The DGAT1 p.Lys232Ala polymorphism revealed a high genetic variance for fat percentage, unsaturated C18, C16:0, and SFA/UFA. Although the effect of this polymorphism was not so evident for short chain fatty acids such as C4:0-C8:0, it was significant for C14:0 fatty acids. We concluded that selective breeding of carriers of the A allele in Romanian Holsteins can contribute to improvement in unsaturated fatty acids content of milk. However, in buffalo, the lack of the A allele makes selection inapplicable because only the K allele, associated with higher saturated fatty acids contents in milk, was identified.

    The history of cholera, a specific infection caused by Vibrio Cholerae, starts in ancient times. The sixth pandemic that began in 1899 and lasted until 1923, started in India and came to Eastern Europe through Russia. The expansion of the epidemic in the Balkans was facilitated both by the 2 Balkan Wars and the First World War. Romania, as a participant in these wars was affected by cholera, which was especially common among the army during the Balkan War. If the original source of the cholera issue is still controversial, both Romanians and Bulgarians accusing each other of being the basis of the outbreaks south of the Danube, it is widely recognized that the extent of the disease was facilitated by the sanitary conditions of food preparation and drinking water sources among both Romanian soldiers and in the civilian population. Under these conditions, in addition to numerous measures against cholera taken by the Ministry of War, Prof. I. Cantacuzino successfully experiments outbreak vaccination for the first time in the world with a vaccine prepared by himself and his collaborators. The vaccine containing 25 breeds of vibriones was a success in terms of rapid development of a preparation, the application of which was achieved through a quick campaign and proved extremely efficient, imposing the Romanian method as an effective way to combat a disease in full outbreak.

    Medical anthropology is the teaching of the ill human being, of being ill; anthropological medicine is the realization of this teaching in practice. This concept was first developed and assessed in the "Gestaltkreis" and in the Pathosophy (44), in Medicine in Motion (39), and in the Bipersonality (10). The four most important concepts are represented, which have their origin and aim in anthropological medicine: anthropological medicine, Balint-work, family-oriented medicine, and salutogenesis. These concepts are exemplified in the Aachen psychosomatic liaison model, the Aachen Balint cooperation model, and the Aachen model of psychosomatic care. We wish to portray the meaning of these resources for the medicine of the future, since they have proven to be effective, cost-saving, and easy to be handled. In the latter part of our presentation, we will document this point with a pilot study conducted in Israel and in our own clinic in Aachen. PMID:11603206

    Physicians have struggled with the medical ramifications of athletic competition since ancient Greece, where rational medicine and organized athletics originated. Historically, the relationship between sport and medicine was adversarial because of conflicts between health and sport. However, modern sports medicine has emerged with the goal of improving performance and preventing injury, and the concept of the "team physician" has become an integral part of athletic culture. With this distinction come unique ethical challenges because the customary ethical norms for most forms of clinical practice, such as confidentiality and patient autonomy, cannot be translated easily into sports medicine. The particular areas of medical ethics that present unique challenges in sports medicine are informed consent, third parties, advertising, confidentiality, drug use, and innovative technology. Unfortunately, there is no widely accepted code of sports medicine ethics that adequately addresses these issues.

    2015-01-01

    Since its first use in the steroid field in the late 1950s, the use of fluorine in medicinal chemistry has become commonplace, with the small electronegative fluorine atom being a key part of the medicinal chemist's repertoire of substitutions used to modulate all aspects of molecular properties including potency, physical chemistry and pharmacokinetics. This review will highlight the special nature of fluorine, drawing from a survey of marketed fluorinated pharmaceuticals and the medicinal chemistry literature, to illustrate key concepts exploited by medicinal chemists in their attempts to optimize drug molecules. Some of the potential pitfalls in the use of fluorine will also be highlighted.

  15. Palliative medicine in Britain.

    PubMed

    Doyle, Derek

    In Britain, Palliative Medicine was recognized as a subspecialty of Internal Medicine exactly 20 years after Cicely Saunders founded St Christopher's, at exactly the same time that government was at last recognizing the worth and the needs of general practice. Both had far-reaching effects and implications for patients, doctors, and the future of medicine. For Palliative Medicine it meant units wishing to train specialists going through a rigorous selection process; the development of an equally rigorous training program for the doctors who had already gained a higher qualification before starting Palliative Medicine, demonstrating the need for and benefits of palliative medicine to the sceptics in the profession and, now, continuing to recruit the staff for the steadily increasing number of new services. Today there are more Palliative Medicine consultants/specialists than there are oncologists and neurologists combined, with Hospital Palliative Care Teams in every major hospital and cancer center. With nine Chairs in Palliative Medicine, there is now a drive for research and professional education. The specialty faces major challenges, however, ranging from training to care for patients with non-malignant disease to enabling patients to die in the place of their choice-something that rarely happens today; from defining what is distinctive or unique about palliative medicine to clarifying the respective place of general practice and the specialty. Most would agree that the biggest challenge for the young, thriving specialty is how to share its principles with other doctors wherever they work. PMID:18051021

  18. pH-Dependent Metal Ion Toxicity Influences the Antibacterial Activity of Two Natural Mineral Mixtures

    PubMed Central

    Cunningham, Tanya M.; Koehl, Jennifer L.; Summers, Jack S.; Haydel, Shelley E.

    2010-01-01

    Background Recent studies have demonstrated that several mineral products sold for medicinal purposes demonstrate antimicrobial activity, but little is known about the physicochemical properties involved in antibacterial activity. Methodology/Principal Findings Using in vitro mineral suspension testing, we have identified two natural mineral mixtures, arbitrarily designated BY07 and CB07, with antibacterial activity against a broad-spectrum of bacterial pathogens. Mineral-derived aqueous leachates also exhibited antibacterial activity, revealing that chemical, not physical, mineral characteristics were responsible for the observed activity. The chemical properties essential for bactericidal activity against Escherichia coli were probed by testing antibacterial activity in the presence of metal chelators, the hydroxyl radical scavenger, thiourea, and varying pH levels. Chelation of the BY07 minerals with EDTA or desferrioxamine eliminated or reduced BY07 toxicity, respectively, suggesting a role of an acid-soluble metal species, particularly Fe3+ or other sequestered metal cations, in mineral toxicity. This conclusion was supported by NMR relaxation data, which indicated that BY07 and CB07 leachates contained higher concentrations of chemically accessible metal ions than leachates from non-bactericidal mineral samples. Conclusions/Significance We conclude that the acidic environment of the hydrated minerals significantly contributes to antibacterial activity by increasing the availability and toxicity of metal ions. These findings provide impetus for further investigation of the physiological effects of mineral products and their applications in complementary antibacterial therapies. PMID:20209160

    1998-07-01

    Nanobacteria are the smallest cell-walled bacteria, only recently discovered in human and cow blood and in commercial cell culture serum. In this study, we identified with energy-dispersive x-ray microanalysis and chemical analysis that all growth phases of nanobacteria produce biogenic apatite on their cell envelope. Fourier transform IR spectroscopy revealed the mineral as carbonate apatite. Previous models for stone formation have lead to a hypothesis that an elevated pH due to urease and/or alkaline phosphatase activity are important lithogenic factors. Our results indicate that carbonate apatite can be formed without these factors at pH 7.4 at physiological phosphate and calcium concentrations. Due to their specific macromolecules, nanobacteria can produce apatite very efficiency in media mimicking tissue fluids and glomerular filtrate and rapidly mineralizing most of available calcium and phosphate. This can be also monitored by (superscript 85)Sr incorporation and provides a unique model for in vitro studies on calcification. Recently, bacteria have been implicated in the formation of carbonate (hydroxy)fluorapatite in marine sediments. Apatite grains are found so commonly in sedimentary rocks that apatite is omitted in naming the stone. To prove that apatite and other minerals are formed by bacteria would implicate that the bacteria could be observed and their actions followed in stones. We have started to approach this in two ways. Firstly, by the use of sensitive methods for detecting specific bacterial components, like antigens, muramic acid and nucleic acids, that allow for detecting the presence of bacteria and, secondly, by follow-up of volatile bacterial metabolites observed by continuous monitoring with ion mobility spectrometry, IMCELL, working like an artificial, educatable smelling nose. The latter method might allow for remote real time detection of bacterial metabolism, a signature of life, in rocks via fractures of drillholes with or without

    Moradian-Oldak, Janet

    2012-01-01

    Enamel is a hard nanocomposite bioceramic with significant resilience that protects the mammalian tooth from external physical and chemical damages. The remarkable mechanical properties of enamel are associated with its hierarchical structural organization and its thorough connection with underlying dentin. This dynamic mineralizing system offers scientists a wealth of information that allows the study of basic principals of organic matrix-mediated biomineralization and can potentially be utilized in the fields of material science and engineering for development and design of biomimetic materials. This chapter will provide a brief overview of enamel hierarchical structure and properties as well as the process and stages of amelogenesis. Particular emphasis is given to current knowledge of extracellular matrix protein and proteinases, and the structural chemistry of the matrix components and their putative functions. The chapter will conclude by discussing the potential of enamel for regrowth. PMID:22652761

    In the ten years since the publication of the national Bureau of Standards comprehensive tables of thermochemical properties, by Rossini and other (1952), a very large body of modern calorimetric and equilibrium data has become available. Because of the complex interrelations among many thermochemical data and the necessity for internal consistency among these values, a complete revision of this standard reference is required. This is also true of the summaries of thermochemical data for the sulfides (Richardson and Jeffes 1952) and for the oxides (Coughlin 1954). The following tables present critically selected values for the heat and free energy of formation, the logarithm of the equilibrium constant of formation Log Kf, the entropy and the molar volume, at 298.15°K (25.0°C) and one atmosphere for minerals.

    Four patients are described in whom pneumoconiosis was diagnosed towards the end of a lifetime's work in shale mines. All developed complicated pneumoconiosis, diagnosed in two cases at necropsy, in one by lobectomy, and in one radiologically. Two of the patients were found at necropsy also to have peripheral squamous lung cancer.The clinical and histological features of the disease resembled the pneumoconioses of coalminers and kaolin workers and the lungs of three of the patients were shown to contain dust composed predominantly of kaolinite, mica, and silica. Shale miners' complicated pneumoconiosis has not previously been described. Although the British shale industry is now defunct, oil production from shale is expanding in other countries, notably the USA. It is suggested that control should be exercised over dust exposure levels in this industry and that epidemiological studies should be carried out to quantify the risks of both pneumoconiosis and bronchial carcinoma.

    This book is the forty-first in the Elsevier Oceanography Series, and with it the series has come full circle. Its first title, published in 1964, was John Mero's landmark study The Mineral Resources of the Sea [Mero, 1964]. Looking back at that first major treatise and comparing it with this and other recent books on the topic [e.g., Teleki et al., 1987] one cannot help but be impressed with how well Mero used the sparse data and studies that had been put together by his time. Twenty-two years and many millions of dollars later a substantial mining-oriented base of knowledge has been built — we know much more about the economics and the engineering — yet the basic premises and conclusions that Mero assembled are still intact, and answers to the fundamental questions (e.g., formation processes for manganese nodules) are not in much better condition than they were then.

  5. Minerals Bill introduced in House

    A bill that aims to strengthen a national minerals policy and to establish a three-member White-House-level council to coordinate the development of this policy was introduced in the House of Representatives on April 30 by James D. Santini (D-Nev.). Entitled the National Minerals Security Act (NMSA), the legislation, if passed, also would amend tax laws to assist the mining industry to make capital investments to locate and produce strategic minerals; it would provide the means for the Secretary of the Interior to make withdrawn public lands available for mineral development; and it would create a revolving fund for the sale and purchase of strategic minerals.Santini estimates that 4 billion tons of minerals are needed annually to sustain the nation's economy. Much of the minerals are supplied by other nations, however; Santini wants to see an end to the United States' dependence on foreign countries, especially those that seem relatively unstable politically. ‘The U.S. has placed its national security in the hands of a few foreign nations,’ Santini said in a recent press conference. ‘We are heavily dependent on the region of southern Africa for 76% of our cobalt, 93% of our platinum, 48% of our chromium, and a host of other strategic and critical minerals. Without these minerals, we cannot build jet aircraft, weapons, or other military hardware vitally important to our national security.’

    Herbal pharmaceuticals in medical practice are similarly used as chemically well defined drugs. Like other synthetical drugs, they are subject to pharmaceutical legislature (AMG) and EU directives. It is to differentiate between phytopharmaceuticals with effectiveness of proven indications and traditional registered herbal medicine.

The result is that more and more well-established preparations disappear from the market. This article gives an overview of practical relevant indications for herbal medicines, which according to its licensing status, the scientific assessment by the Cochrane Collaboration and the Institute for Quality and Efficiency in Health Care (IQWiG) and evidence-based Medicine (EBM)/ meta-analyzes as an alternative to synthetics can be used.

    Listeria monocytogenes is a facultative intracellular foodborne pathogen responsible for listeriosis. In a recent study, in which we investigated neglected exogenous routes of transmission of foodborne pathogens into the European Union, we have isolated 15 L. monocytogenes strains in food products, which were imported from the Republic of Moldavia to Romania and illegally sold at a local market. The aim of this study was to characterize the subtype and virulence potential of these 15 L. monocytogenes strains. Multilocus sequence typing revealed that these L. monocytogenes strains belong to six different sequence types (ST2, ST8, ST9, ST20, ST121 and ST155). In addition, in vitro virulence assays using human intestinal epithelial Caco2 and macrophage-like THP1 cells showed a high strain variability regarding the invasion efficiency in Caco2 cells (0.98-2.78%) and the intracellular growth rate in both cell types. Both ST121 strains and the ST9 isolate were unable to invade Caco2 cells, and all ST155 strains showed no proliferation inside macrophages and revealed low cytotoxicity. Furthermore we performed sequence analysis of three main virulence factors: PrfA, internalin A (InlA) and listeriolysin O (LLO). The Romanian food isolates showed a high diversity in the InlA and LLO amino acid sequences, whereas the amino acid sequence of PrfA of all strains was identical. Overall, the amino acid sequences of PrfA, InlA and LLO were identical for strains belonging to the same ST. We detected in total 30 different amino acid substitutions, resulting in seven different InlA variants, two of which have not yet been described. The three strains, which were unable to invade Caco2 cells, harboured a premature stop codon resulting in truncated InlA. Furthermore, we detected four different amino acid substitutions in the LLO sequence, which are present in four variants. The number of LLO mutations correlates negatively with intracellular growth in Caco2 and THP1 cells and

  8. Mineral Detector for Igneous Rocks

    We present a Raman spectral analysis tool that uses machine learning algorithms to classify pure minerals in igneous rocks. Experiments show greater than 90% accuracy classifying a test set of pure minerals against a database of similar reference minerals using an artificial neural network. Efforts are currently underway to improve this tool for use as a mineral detector in rock samples, an important milestone toward autonomously classifying rocks based on spectral, and previous imaging work. Although pure mineral classification has been widely successful, applying the same methods to rocks is difficult because the spectra may represent a combination of multiple, and often competing, mineral signatures. In such cases some minerals may appear with more intensity than others resulting in masking of weaker minerals. Furthermore, with our particular spectrometer (852 nm excitation, ~50 micron spot size), minerals such as potassium feldspar fluoresce, both obscuring its characteristic Raman features and suppressing those of weaker minerals. For example, plagioclase and quartz, two key minerals for determining the composition of igneous rocks, are often hidden by minerals such as potassium feldspar and pyroxene, and are consequently underrepresented in the spectral analysis. These technicalities tend to skew the perceived composition of a rock from its actual composition. Despite these obstacles, an experiment involving a training set of 26 minerals (plagioclase, potassium feldspar, pyroxene, olivine, quartz) and a test set of 57 igneous rocks (basalt, gabbro, andesite, diorite, dacite, granodiorite, rhyolite, granite) shows that generalizations derived from their spectral data are consistent with expected trends: as rock composition goes from felsic to mafic there is a marked increase in the detection of minerals such as plagioclase and pyroxene along with a decrease in the detection of minerals such as quartz and potassium feldspar. The results suggest that phaneritic

    The University of Maryland Department of Epidemiology and Public Health collaborated with the Center for Integrative Medicine at the same institution to develop and implement a unique integrative medicine curriculum within a preventive medicine residency program. Between October 2012 and July 2014, Center for Integrative Medicine faculty provided preventive medicine residents and faculty, and occasionally other Department of Epidemiology and Public Health faculty, with comprehensive exposure to the field of integrative medicine, including topics such as mind-body medicine, nutrition and nutritional supplements, Traditional Chinese Medicine, massage, biofield therapies, manual medicine, stress management, creative arts, and the use of integrative medicine in the inpatient setting. Preventive medicine residents, under the supervision of Department of Epidemiology and Public Health faculty, led integrative medicine-themed journal clubs. Resident assessments included a case-based knowledge evaluation, the Integrative Medicine Attitudes Questionnaire, and a qualitative evaluation of the program. Residents received more than 60 hours of integrative medicine instruction, including didactic sessions, experiential workshops, and wellness retreats in addition to clinical experiences and individual wellness mentoring. Residents rated the program positively and recommended that integrative medicine be included in preventive medicine residency curricula. The inclusion of a wellness-focused didactic, experiential, and skill-based integrative medicine program within a preventive medicine residency was feasible and well received by all six preventive medicine residents.

    Moses Maimonides, the illustrious medieval rabbi and philosopher, dedicated the last decade of his life primarily to medicine. His strong interest in medicine was an integral component of his religious-philosophical teachings and world view. In this paper various sources from his rabbinic writings are presented that explain Maimonides’ motivation regarding and deep appreciation for medicine: (A) The physician fulfills the basic biblical obligation to return lost objects to their owner, for with his knowledge and experience the physician can restore good health to his sick fellow human being; (B) medicine provides a unique opportunity to practice imitatio dei, as it reflects the religious duty to maintain a healthy life-style; (C) as an important natural science, medicine offers tools to recognize, love, and fear God. These three aspects address man’s relationship and obligation towards his fellow-man, himself and God. Biographical insights supported by additional sources from Maimonides’ writings are discussed.

Three themes prominent in the text are: 'the birth of the clinic', 'the clinical gaze' and the power-knowledge relationship. Three problematics identified in modern medicine by Foucault and which are particularly relevant to twentieth century medicine are: (i) the extension of the clinical gaze from the individual body to the wider population; (ii) the increasing medical intervention and use of technology in fundamental life processes; and (iii) the relationship between society and medicine. I will argue that Foucault's analysis is fraught with ambiguities. It is useful, however, for establishing an explanation for medicine today and for presenting a particular interpretation of modernity.

  17. Ayurvedic medicine. Core concept, therapeutic principles, and current relevance.

    In the prebiblical Ayurvedic origins, every creation inclusive of a human being is a model of the universe. In this model, the basic matter and the dynamic forces (Dosha) of the nature determine health and disease, and the medicinal value of any substance (plant and mineral). The Ayurvedic practices (chiefly that of diet, life style, and the Panchkarama) aim to maintain the Dosha equilibrium. Despite a holistic approach aimed to cure disease, therapy is customized to the individual's constitution (Prakruti). Numerous Ayurvedic medicines (plant derived in particular) have been tested for their biological (especially immunomodulation) and clinical potential using modern ethnovalidation, and thereby setting an interface with modern medicine. To understand Ayurvedic medicine, it would be necessary to first understand the origin, basic concept and principles of Ayurveda. PMID:11795092

    The U.S. Department of Energy's National Energy Technology Laboratory (NETL) located in Albany, OR (formerly the Albany Research Center) has studied ex situ mineral carbonation as a potential option for carbon dioxide sequestration. Studies focused on the reaction of Ca-, Fe-, and Mg-silicate minerals with gaseous CO2 to form geologically stable, naturally occurring solid carbonate minerals. The research included resource evaluation, kinetic studies, process development, and economic evaluation. An initial cost estimate of approximately $69/ton of CO2 sequestered was improved with process improvements to $54/ton. The scale of ex situ mineral carbonation operations, requiring 55 000 tons of mineral to carbonate, the daily CO2 emissions from a 1-GW, coal-fired power plant, may make such operations impractical.

    Background. The predictive value of frailty assessment is still debated. We analyzed the predictive value of frailty of independent living elderly. The outcomes variables were visits to the general practitioner, hospital admission, and occurrence of new health problems. Methods. A one-year follow-up study was executed among 215 community-living old Romanians. General practitioners reported the outcome variables of patients, whose frailty was assessed one year before, using the Groningen Frailty Indicator. The predictive validity is analyzed by descriptive and regression analysis. Results. Three-quarters of all participants visited their general practitioner three times more last year and one-third were at least once admitted to a hospital. Patients who scored frail one year before were more often admitted to a hospital. Visits to the general practitioner and occurrence of new health problems were not statistically significant related to frailty scores. The frailty items polypharmacy, social support, and activities in daily living were associated with adverse outcomes. Conclusions. The predictive value of frailty instruments as the Groningen Frailty Indicator is still limited. More research is needed to predict health outcomes, health care utilization, and quality of life of frailty self-assessment instruments. Validation research on frailty in different “environments” is recommended to answer the question to what extent contextual characteristics influence the predictive value. PMID:27493663

  2. Identification of rumanite (Romanian amber) as thermally altered succinite (Baltic amber)

    NASA Astrophysics Data System (ADS)

    Stout, E. C.; Beck, C. W.; Anderson, K. B.

    Romanian amber (rumanite) has been considered to be a separate species of fossil resin for more than a century. While earlier investigators held it to be very similar to succinite (Baltic amber), modern scholars have assigned it a distinctly different botanical origin. We have found that almost all of the constituents of the ether-soluble fractions of 13 specimens of authentic rumanite identified by gas chromatography-mass spectrometry have previously been reported in the soluble fraction of succinite, including succinic acid and its monoterpene esters. Additionally and significantly, the soluble fraction of rumanite contains a number defunctionalized compounds that do not preexist in succinite, but that are produced by pyrolysis of whole succinite or of its insoluble polymeric fraction. Simultaneous methylation pyrolysis-gas chromatography-mass spectrometry of the polymeric fraction of seven of the rumanite specimens yielded further copious amounts of dimethyl succinate, a number of diterpene resin acid methyl esters, and additional defunctionalized compounds known to be pyrolysis products of succinite. The evidence shows conclusively that the botanical origin of rumanite is not distinct from that of succinite. Rather, rumanite is a succinite that has suffered partial thermal degradation in the course of the folding of the Oligocene Kliwa sandstone formation in which it is most commonly found.

    The purpose of this study was to investigate the occurrence of Salmonella in raw chicken meat samples collected at the Romanian seaside and to evaluate the antimicrobial susceptibility of the isolates. In 2012, 317 chicken meat samples from slaughterhouses (n = 289) and retail markets (n = 28) were evaluated. Overall, 13.2% (42) of the samples contained Salmonella; 12.8% (37) and 17.8% (5) from the chicken carcasses at slaughterhouses and the fresh meat from retail markets, respectively. Eight serotypes of Salmonella enterica subsp. enterica were identified: Infantis (18 isolates), Bredeney (7), Virchow (6), Djugu (4), Grampian (4), Brandenburg (1), Derby (1), and Ruzizi (1). The isolates were resistant to tetracycline (66.6% of isolates), nalidixic acid (64.3%), sulfamethoxazole (64.3%), ciprofloxacin (61.9%), streptomycin (59.5%), trimethoprim (33.3%), ampicillin (9.5%), chloramphenicol (7.1%), and gentamicin (2.4%). No resistance was found to cefotaxime and ceftazidime. Thirty (71.4%) of the 42 tested isolates had multidrug resistance patterns to at least two antimicrobials. This survey highlighted a multidrug-resistant Salmonella contamination rate in raw chicken meat in this area of Romania, which can seriously threaten human health. PMID:25951397

    The personality of Prof. Dr. Constantin Arseni (1912-1994) is without any doubt a key point in any discussion regarding the history of the Romanian School of Neurosurgery. Now at two decades since the regretted passing-away of Prof. Arseni the authors present several pieces of data regarding the early beginnings of neurosurgery in Romania and how this discipline has evolved over time in our country. Driven by an incredible tenacity Professor Constantin Arseni managed not only to create the first completely independent clinic of neurosurgery in Romania, but also to keep it continuously updated with the latest bibliographic and technological resources available at the time. Professor Arseni's masterpiece, the largest neurosurgical hospital in Europe (at the time of its construction)was supposed to be a completely autonomous institute dedicated to surgery on the human central nervous system. As the Iron Curtain fell and Europe was marked by continuous reforms, the idea of an institute dedicated to the brain was abandoned by the authorities and a multidisciplinary hospital dedicated to neurosurgical emergencies and trauma was born.

    Purpose of the work: wave breaking and wave run-up on a gently sloping plane beach from Romanian Black Sea Coast. That coast has a length of 244 km and an almost linear configuration with the exception of build-up areas. The paper concentrates on shoaling of regular waves and spilling type of wave breaking running with a simulation on software MIKE 21. Research and methodology: the paper contents the measurements for spilling and plunging type of breakers on a plane sloping beach with a slope of 1/45 starting in depth of 0.23 m to 0.46 m. A moving shoreline is included in the simulations. With respect to the parameters of the breaker model the standard values are applied. An explicit filter is introduced near the still water shoreline to remove short-wave instabilities and to dissipate the wave energy in the model. Results: the obtained values indicate the wave breaking and wave run-up processes, the spatial variation of a number of phase-averaged quantities and the shoreline motion converted intro a vertical and a horizontal displacement.

    The first objective of this study was to investigate whether police violence is more tolerated when the victim is a member of a social minority (e.g., Moroccan immigrants and Romanian Gypsies in Spain) than when the victim is a member of the social majority (e.g., Spaniards). The second objective was to use Schwartz value theory to examine the moderating role of values on attitudes towards tolerance of police violence. The participants were 207 sociology and social work students from a public university in Madrid. Overall, in this study, police violence was more accepted when the victim was a member of a social minority; F(2, 206) = 77.91, p = .001, ηp 2 = 0.433, and in general, values moderated this acceptance. Thus, greater adherence to the conservation and self-promotion values subsystems would strengthen support for police violence towards a social minority member. On the other hand, greater adherence to the openness to change and self-transcendence subsystems diminish this support.

    2010-05-15

    The present study described reflectance spectroscopy as a suitable analytical tool to discriminate the floral origin of 39 Romanian propolis samples. Relevant differences between the UV-vis reflectance spectra of the investigated propolis samples within the 220-850nm spectral range were found. The results obtained applying cluster analysis, principal component analysis and linear discriminant analysis to the digitized data of zero order, zero order normalized and first order derivative spectra support the reliability of this technique. In addition, the application of the linear discriminant analysis to the score matrices corresponding to the first principal components appeared to be an illuminating solution. Generally, the samples have been assigned to two large groups in a good agreement with their vegetal sampling location, samples originating from predominant forest area and samples originating from meadows. Within the first group, two subgroups were identified according to the dominant type of the forest, deciduous or resinous, while within the last group three subgroups were found according to the extend and variety of the meadow.

  8. Late-glacial and Holocene river development in the Teleorman Valley on the southern Romanian Plain

    This paper reports on a radiocarbon-dated sequence of alluvial terraces from the Teleorman Valley in the southern Romanian Plain and represents the first Late-glacial and well-constrained Holocene alluvial sequence from the lower Danube Valley of southeast Europe. The two earliest and most extensive terraces (T1 and T2) are dissected by large, high-amplitude palaeochannels, which are dated to ca. 12 800 yr BP and are comparable to large meandering palaeochannels identified from other Late glacial contexts across northern and central Europe. The remaining sequence of alluvial deposits show changes in river activity and accelerated sedimentation around 4900-4800 yr BP, 4000-3800 yr BP, 3300-2800 yr BP, 1000 yr BP and within the past 200 yr. A phase of tributary stream alluvial fan deposition is dated to ca. 2400 yr BP. All these periods of alluvial sedimentation correlate well with episodes of climatic cooling, higher rainfall and enhanced river activity, both in terms of incision and greater lateral mobility as well as increased flood frequency and magnitude identified elsewhere in central, western and northern Europe. Human activity appears to have had little effect on this river environment and significant fine-grained sedimentation is not noted until ca. 2400 yr BP, approximately 5000 yr after the first neolithic farmers settled the area. Whether this record of river activity truly reflects the impact of prehistoric societies on this catchment will only be elucidated through further, ongoing detailed archaeological research.

    2014-12-01

    Since the 2010 remote-sensing discovery of lunar regolith rich in Mg-Al spinel on the rims and central peaks of impact craters and inner rings of basins on the Moon, researchers have been designing experiments to better understand the origin and formation history of spinel-rich rocks and what they mean for the construction of the lunar crust. The newly detected rock type is referred to as pink spinel anorthosite, or PSA, due to high plagioclase and low abundance (<5%) of mafic minerals such as olivine and pyroxene. Two recent studies tested specific hypotheses of PSA production on the Moon. Juliane Gross (American Museum of Natural History and the Lunar and Planetary Institute, LPI) and colleagues at the LPI, University of Hawaii, and NASA Johnson Space Center conducted experiments to model the crystallization of spinel in impact melts from impact events. Tabb Prissel (Brown University) and colleagues from Brown conducted experiments to model a plutonic formation of spinel from magma-wallrock interactions. In each study, comparisons of the remote sensing data with Apollo lunar samples or lunar meteorites were crucial for testing the PSA formation hypotheses with the experimental results. Definitive answers aren't in yet. PSA could form from impact melting of the right target rocks. Equally likely is PSA formation by reaction of basaltic magma and crust. One big unknown is the effect space weathering has in determining the amount of spinel in the PSA..

  14. Universal ripper miner

    Morrell, Roger J.; Larson, David A.

    1991-01-01

    A universal ripper miner used to cut, collect and transfer material from an underground mine working face includes a cutter head that is vertically movable in an arcuate cutting cycle by means of drive members, such as hydraulically actuated pistons. The cutter head may support a circular cutter bit having a circular cutting edge that may be indexed to incrementally expose a fresh cutting edge. An automatic indexing system is disclosed wherein indexing occurs by means of a worm gear and indexing lever mechanism. The invention also contemplates a bi-directional bit holder enabling cutting to occur in both the upstroke and the downstroke cutting cycle. Another feature of the invention discloses multiple bits arranged in an in-line, radially staggered pattern, or a side-by-side pattern to increase the mining capacity in each cutting cycle. An on-board resharpening system is also disclosed for resharpening the cutting edge at the end of cutting stroke position. The aforementioned improvement features may be used either singly, or in any proposed combination with each other.

    A study on the evolution with age of the mineral composition of bones was performed on samples belonging to human and other common mammalian species (cattle, sheep, dog). The study was carried out on the ashes obtained by calcination of the bone samples (1 h at 900 degrees C). The calcined powders were carefully examined by X-ray diffraction, from which precise quantitative evaluation (also confirmed by chemical analysis) of the crystalline phases present was derived. These data were analysed as a function of the introduced fractional age phi, a new relative scale that allows even largely different lifespan species to be compared. An overall linear increase in (Ca + Mg)/P ratio with log phi was found and the other considerations on molecular constitution (especially as regards Mg2+ substituting for Ca2+ in very young subjects) of the various phases detected were formulated and relative implications evaluated. The results appear promising for an improvement of knowledge in the field of biomedical experimentation and clinical implantology.

  16. Mineral Commodity Profiles: Selenium

    USGS Publications Warehouse

    Butterman, W.C.; Brown, R.D.

    2004-01-01

    Overview -- Selenium, which is one of the chalcogen elements in group 16 (or 6A) of the periodic table, is a semiconductor that is chemically similar to sulfur for which it substitutes in many minerals and synthetic compounds. It is a byproduct of copper refining and, to a much lesser extent, lead refining. It is used in many applications, the major ones being a decolorizer for glass, a metallurgical additive to free-machining varieties of ferrous and nonferrous alloys, a constituent in cadmium sulfoselenide pigments, a photoreceptor in xerographic copiers, and a semiconductor in electrical rectifiers and photocells. Refined selenium amounting to more than 1,800 metric tons (t) was produced by 14 countries in 2000. Japan, Canada, the United States, and Belgium, which were the four largest producers, accounted for nearly 85 percent of world production. An estimated 250 t of the world total is secondary selenium, which is recovered from scrapped xerographic copier drums and selenium rectifiers; the selenium in nearly all other uses is dissipated (not recoverable as waste or scrap). The present selenium reserve bases for the United States and the world (including the United States), which are associated with copper deposits, are expected to be able to satisfy demand for selenium for several decades without difficulty.

    1993-10-01

    In Europe different types of water are marketed, each strictly defined by EC Directive 80/777 (Natural Mineral Water, Spring and Table Water) or 80/778 (Drinking Water). In Germany, an additional type of water is common in the market: curative/medical water. Product quality and safety, registration as medicine, and pharmaceutical control are defined by the German Federal Medicine Act. A medical water is treated as any other medicine and may be sold only in pharmacies. The use of any water in Germany is controlled and strictly regulated by the Federal Water Act (Fricke 1981). The following requirements are set by the act: (1) No water use without a permit, which is limited in time and quantity. (2) No single or juristic person may own water. (3) Water resources of public interest and their recharge areas are to be protected by the definition of water protection zones. (Natural mineral water is not of public interest and therefore is not required to be protected by the definition of water protection zones, although it represents a market value of more than US2 billion. Medical water is of public interest). The definition of water protection zones impacts private property rights and has to be handled carefully. In order to protect water resources, sometimes the economic basis of a traditional industrial and/or agricultural infrastructure is destroyed. The concerns and needs all citizens, including industry, must be considered in analyzing the adequacy of water protection zones.

    There is increasing awareness of the role that metals/minerals play in health and disease. Minerals contribute in essential ways to the fundamental biochemical and physiological functions of cells. Deficit of an essential mineral leads to aberrations in cell function. Alternatively, minerals in excess have significant toxicity, and in an era of increasing threat to a safe environment, the potential for toxic tissue injury to contribute to progressive renal insufficiency and ultimately to unexplained renal failure remains a major concern. This review provides information on selected minerals that are attracting growing attention with respect to their influence on renal function in health and disease. Although all minerals have the potential to cause toxicity if consumed in sufficient quantity, most are essential nutrients whose deficiency is associated with significant health problems. Certain minerals, including aluminum, arsenic, cadmium, lead, and mercury are considered toxic. Their suggested positive effects on the health of animals has been recently summarized, but in humans they are not currently known to exert any clearly beneficial biological or biochemical effect.

  8. Economic drivers of mineral supply

    2003-01-01

    The debate over the adequacy of future supplies of mineral resources continues in light of the growing use of mineral-based materials in the United States. According to the U.S. Geological Survey, the quantity of new materials utilized each year has dramatically increased from 161 million tons2 in 1900 to 3.2 billion tons in 2000. Of all the materials used during the 20th century in the United States, more than half were used in the last 25 years. With the Earth?s endowment of natural resources remaining constant, and increased demand for resources, economic theory states that as depletion approaches, prices rise. This study shows that many economic drivers (conditions that create an economic incentive for producers to act in a particular way) such as the impact of globalization, technological improvements, productivity increases, and efficient materials usage are at work simultaneously to impact minerals markets and supply. As a result of these economic drivers, the historical price trend of mineral prices3 in constant dollars has declined as demand has risen. When price is measured by the cost in human effort, the price trend also has been almost steadily downward. Although the United States economy continues its increasing mineral consumption trend, the supply of minerals has been able to keep pace. This study shows that in general supply has grown faster than demand, causing a declining trend in mineral prices.

    Outgassing minerals at elevated temperatures prior to BET measurements can lead to phase changes, especially in the case of amorphous and poorly crystalline materials. In order to evaluate the applicability of the BET method when low outgassing temperatures are required, selected aquifer minerals were outgassed at different temperatures and for different times. The studied minerals are 2-line ferrihydrite, goethite, lepidocrocite, quartz, calcite, alpha-alumina, and kaolinite. The results demonstrate that measured specific surface areas of iron oxides are strongly dependent on outgassing conditions because the surface area increased by 170% with increasing temperature. In the poorly crystalline minerals, phase changes caused by heating were observed at temperatures lower than 100 degrees C. Therefore low outgassing temperatures are preferable for minimizing phase changes. As demonstrated in this study, stable BET values can be obtained by increasing the outgassing time without heating iron oxides. For quartz, calcite, alpha-alumina, and kaolinite, stable BET values were obtained after outgassing the minerals at 100 to 250 degrees C for 2 h. However, outgassing these minerals at room temperature (20 degrees C) only resulted in minor errors, implying that aquifer sediments containing poorly crystalline materials can be outgassed at low temperatures if the outgassing time is increased. Scanning electron microscopy of the studied minerals demonstrated that the particle size as calculated from BET data compares well with particle size observed by scanning electron microscopy images.

    To experience the integration of traditional Chinese medicine (TCM) in China was 'the chance of a lifetime; thanks to the support of the Winston Churchill Memorial Trust. The scale and range of TCM available in terms of health care provision, education and research is unique in the world. This holistic integrative medicine is part of Chinese culture. Regulation and training of practitioners has similarities with current structures emerging in the UK in preparation for the statutory regulation for acupuncture and herbal medicine. China's research activity is a critical component of informing the debate on evidence-based practice and now real opportunities for collaboration and dissemination are beginning to emerge.

    The aim of preventive medicine is the absence of disease, either by preventing the occurrence of a disease or by halting a disease and averting resulting complications after its onset. Preventive medicine can be practised by governmental agencies, primary care physicians and the individual himself. In the past, many diseases have been conquered by doing things for the individual. The present challenge of preventive medicine is to motivate the individual to practise his own prevention. Possible means of achieving this motivation are described and many require the active participation of the primary care physician. PMID:20469128

  13. Mineral Commodity Profiles -- Rubidium

    Butterman, W.C.; Reese, R.G.

    2003-01-01

    Overview -- Rubidium is a soft, ductile, silvery-white metal that melts at 39.3 ?C. One of the alkali metals, it is positioned in group 1 (or IA) of the periodic table between potassium and cesium. Naturally occurring rubidium is slightly radioactive. Rubidium is an extremely reactive metal--it ignites spontaneously in the presence of air and decomposes water explosively, igniting the liberated hydrogen. Because of its reactivity, the metal and several of its compounds are hazardous materials, and must be stored and transported in isolation from possible reactants. Although rubidium is more abundant in the earth?s crust than copper, lead, or zinc, it forms no minerals of its own, and is, or has been, produced in small quantities as a byproduct of the processing of cesium and lithium ores taken from a few small deposits in Canada, Namibia, and Zambia. In the United States, the metal and its compounds are produced from imported raw materials by at least one company, the Cabot Corporation (Cabot, 2003). Rubidium is used interchangeably or together with cesium in many uses. Its principal application is in specialty glasses used in fiber optic telecommunication systems. Rubidium?s photoemissive properties have led to its use in night-vision devices, photoelectric cells, and photomultiplier tubes. It has several uses in medical science, such as in positron emission tomographic (PET) imaging, the treatment of epilepsy, and the ultracentrifugal separation of nucleic acids and viruses. A dozen or more other uses are known, which include use as a cocatalyst for several organic reactions and in frequency reference oscillators for telecommunications network synchronization. The market for rubidium is extremely small, amounting to 1 to 2 metric tons per year (t/yr) in the United States. World resources are vast compared with demand.

    It has long been suggested that mineral surfaces played an important role in peptide bond formation on the primitive Earth. However, it remains unclear which mineral species was key to the prebiotic processes. This is because great discrepancies exist among the reported catalytic efficiencies of minerals for amino acid polymerizations, owing to mutually different experimental conditions. This study examined polymerization of glycine (Gly) on nine oxide minerals (amorphous silica, quartz, α-alumina and γ-alumina, anatase, rutile, hematite, magnetite, and forsterite) using identical preparation, heating, and analytical procedures. Results showed that a rutile surface is the most effective site for Gly polymerization in terms of both amounts and lengths of Gly polymers synthesized. The catalytic efficiency decreased as rutile > anatase > γ-alumina > forsterite > α- alumina > magnetite > hematite > quartz > amorphous silica. Based on reported molecular-level information for adsorption of Gly on these minerals, polymerization activation was inferred to have arisen from deprotonation of the NH3 + group of adsorbed Gly to the nucleophilic NH2 group, and from withdrawal of electron density from the carboxyl carbon to the surface metal ions. The orientation of adsorbed Gly on minerals is also a factor influencing the Gly reactivity. The examination of Gly-mineral interactions under identical experimental conditions has enabled the direct comparison of various minerals' catalytic efficiencies and has made discussion of polymerization mechanisms and their relative influences possible Further systematic investigations using the approach reported herein (which are expected to be fruitful) combined with future microscopic surface analyses will elucidate the role of minerals in the process of abiotic peptide bond formation.

    Dentin phosphoproteins are thought to have a primary role in the deposition of mineral on the collagen of dentin. In this study we determined the type of binding between collagen and phosphoproteins necessary for mineral formation onto collagen fibrils and whether the phosphate esters are required. Bovine dentin phosphophoryn or phosvitin from egg yolk were immobilized on reconstituted skin type I collagen fibrils by adsorption or by covalent cross-linking. In some samples the ester phosphate was removed from the covalently cross-linked phosphoproteins by treatment with acid phosphatase. All samples were incubated at 37 degrees C in metastable solutions that do not spontaneously precipitate. Reconstituted collagen fibrils alone did not induce mineral formation. The phosphoproteins adsorbed to the collagen fibrils desorbed when the mineralization medium was added, and mineral was not induced. The mineral induced by the cross-linked phosphoproteins was apatite, and the crystals were confined to the surface of the collagen fibrils. With decreasing medium saturation the time required for mineral induction increased. The interfacial tensions calculated for apatite formation by either phosphoprotein cross-linked to collagen were about the same as that for phosphatidic acid liposomes and hydroxyapatite. This similarity in values indicates that the nucleation potential of these highly phosphorylated surfaces is about the same. It is concluded that phosphoproteins must be irreversibly bound to collagen fibrils for the mineralization of the collagen network in solutions that do not spontaneously precipitate. The phosphate esters of phosphoproteins are required for mineral induction, and the carboxylate groups are not sufficient.

    In a prospective study, we have examined the incidence of fragrance sensitivity in Nottinghamshire coal miners. Our results confirm previous reports of an increased incidence of such sensitivity in miners (45%) when compared with both male (20%) and female (13%) non-miners. This increased incidence is not related to an increased use of perfumed cosmetics, but may be related to the use of a highly perfumed body lotion in subjects who already have a high incidence of irritant hand eczema. There was no significant increase in the rate of positive reactions to other applied allergens.

    The aim of this study was to identify the primary susceptibility HLA-DRB1 alleles associated with GD in Romanian population and to seek whether specific HLA-DRB1 haplotypes are associated with differences in the clinical presentation of GD at diagnosis. Molecular typing of HLA-DRB1 alleles was performed in 77 Romanian Caucasian GD patients and 445 racially matched controls. In GD patients, age, presence of eye disease, goiter grade, autoantibody status and titer, TSH, FT4, FT3, TT3 levels were recorded at diagnosis. The allelic frequencies of HLA-DRB1*03 (41.55% vs. 17.75%, p < 0.0001, χ(2) = 20.81) and DRB1*11 (42.85% vs. 30.56%, p = 0.045, χ(2) = 3.98)were higher, whereas those of HLA-DRB1*01(3.89% vs. 16.40%, p = 0.007, χ(2) = 7.281) and DRB1*15 (10.38% vs. 21.34%, p = 0.038, χ(2) = 4.309)were lower in GD patients than in controls. FT4/TT3 ratio (p = 0.015) and anti-thyroglobulin antibodies (p = 0.024) were higher in *03/11 patients compared to *X/X, *11/Z, *03/Y patients (where X is any other allele than *03 and *11, Y is any other allele than *11, Z is any other allele than *03). In conclusion, HLA-DRB1*03 and DRB1*11 may be the primary susceptibility HLA-DRB1 alleles associated with GD in Romanian population, whereas HLA-DRB1*01 and DRB1*15 seem to be protective. At diagnosis, HLA-DRB1*03/11 GD patients had higher FT4/TT3 ratio and anti-thyroglobulin antibody levels.

    In clinical medicine since some years overdiagnosis is giving rise to growing attention and concern. Overdiagnosis is the diagnosis of a "disease" that will never cause symptoms or death during a patient's lifetime. It is a side effect of testing for early forms of disease which may turn people into patients unnecessarily and may lead to treatments that do no good and perhaps do harm. Overdiagnosis occurs when a disease is diagnosed correctly, but the diagnosis is irrelevant. A correct diagnosis may be irrelevant because treatment for the disease is not available, not needed, or not wanted. Four drivers engender overdiagnosis: 1) screening in non symptomatic subjects; 2) raised sensitivity of diagnostic tests; 3) incidental overdiagnosis; 4) broadening of diagnostic criteria for diseases. "Defensive medicine" can play a role. It begs the question of whether even in the context of Occupational Medicine overdiagnosis is possible. In relation to the double diagnostic evaluation peculiar to Occupational Medicine, the clinical and the causal, a dual phenomenon is possible: that of overdiagnosis properly said and what we could define the overattribution, in relation to the assessment of a causal relationship with work. Examples of occupational "diseases" that can represent cases of overdiagnosis, with the possible consequences of overtreatment, consisting of unnecessary and socially harmful limitations to fitness for work, are taken into consideration: pleural plaques, alterations of the intervertebral discs, "small airways disease", sub-clinical hearing impairment. In Italy the National Insurance for occupational diseases (INAIL) regularly recognizes less than 50% of the notified diseases; this might suggest overdiagnosis and possibly overattribution in reporting. Physicians dealing with the diagnosis of occupational diseases are obviously requested to perform a careful, up-to-date and active investigation. When applying to the diagnosis of occupational diseases, proper

    Astronomy and astrology were combined with medicine for thousands of years. Beginning in Mesopotamia in the second millennium BCE and continuing into the eighteenth century, medical practitioners used astronomy/astrology as an important part of diagnosis and prescription. Throughout this time frame, scientists cited the similarities between medicine and astrology, in addition to combining the two in practice. Hippocrates and Galen based medical theories on the relationship between heavenly bodies and human bodies. In an enduring cultural phenomenon, parts of the body as well as diseases were linked to zodiac signs and planets. In Renaissance universities, astronomy and astrology were studied by students of medicine. History records a long tradition of astrologer-physicians. This chapter covers the topic of astronomy, astrology, and medicine from the Old Babylonian period to the Enlightenment.

    The sexual medicine field has been in mode of revolution until recently. Like all other fields of biomedical research, the economic situation around the world has had a negative impact on the field's momentum-research funding bodies, regulatory bodies and pharmaceutical companies seem to have placed sexual medicine in their low-priority list. But this is not the only challenge the field is facing. The successful development of phosphodiesterase type 5 (PDE5) inhibitors for treatment of erectile dysfunction (ED) means that research in this area seems to have slowed. However, there remain several unmet medical needs within sexual medicine such as premature ejaculation, severe ED and hypoactive sexual desire disorder, which await novel therapeutic approaches. Despite these challenges, research into finding and developing such therapies is likely to continue in the sexual medicine field, in an effort to improve the lives of our patients, who wait for effective therapies.

    The history and the recent state of occupational medicine in Hungary, and its relation with governmental labor organizations are analyzed. In the past 20 years, large "socialist" factories were replaced by smaller companies employing fewer workers. They have been forced to establish contract with occupational health providers. Many of them offer primary care services, whereas family physicians having a board examination in occupational medicine are allowed to work in this field as well. The market of occupational medicine is less regulated, and ethical rules are not always considered. Undercutting prices is a common practice. The recent system could be improved by some regulations which should be respected. There is no reason to make rough changes establishing a new market for profit oriented insurance companies, and to allow employees and employers to work without specification neglecting international agreements. Occupational medicine should be supervised again by the health authorities instead of economists who have quite different, short-term priorities. PMID:22951411

Moreover there is a similarity between pantheistic religion of Hahnemann and magician beliefs in the power named mana in Melanesia and Polinesia or orenda, wakan, manitou and so on, by the Indians from The North America. The amazing thing is that homeopathic chemists belive that kinetic power transforms itself into esoteric one, during preparation of homeopathic medicines.In the end of this article the author ascertains that homeopathic medicine and magic has certain paradigm in common what is opposit to racionalism of official European paradigm of thinking.

    The Bureau of Reclamation (Bureau) conducted studies for a wind turbine field of 100 MW at a site near Medicine Bow, WY, one of the windiest areas in the United States. The wind turbine system would be electrically interconnected to the existing Federal power grid through the substation at Medicine Bow. Power output from the wind turbines would thus be integrated with the existing hydroelectric system, which serves as the energy storage system. An analysis based on 'willingness to pay' was developed. Based on information from the Department of Energy's Western Area Power Administration (Western), it was assumed that 90 mills per kWh would represent the 'willingness to pay' for onpeak power, and 45 mills per kWh for offpeak power. The report concludes that a 100-MW wind field at Medicine Bow has economic and financial feasibility. The Bureau's construction of the Medicine Bow wind field could demonstrate to the industry the feasibility of wind energy.

    In providing minerals to dairy cattle it is important to distinguish between dietary requirements and feeding recommendations. The requirement is the absolute amount of an element needed to meet the animal's metabolic needs for maintenance, growth, pregnancy, and lactation divided by the coefficient of absorption; this is estimated by the factorial method. Actual estimates of requirements for lactating dairy cattle have been determined for Ca and P. The major difficulties in relying on the requirement estimate are that dry matter intake varies and the true absorption coefficient of the mixture of feeds in the ration generally is unknown. Therefore, feeding recommendations, based on feeding graded concentrations of an element, often offer more applicable information. With the exception of Ca and P, the current feeding recommendations for the other macrominerals, Mg, Na, K, Cl and S, have resulted from feeding trials. With certain environmental and physiologic situations the feeding recommendations may vary. For example, during heat stress the dietary K recommendation for the lactating cow should be higher than in cool weather because of increased sweating and decreased feed intake. Another example may be that the source of supplemental Mg may affect what dietary inclusion rate will yield optimal performance and should be recommended. An important consideration in dairy ration formulation in the future will address the interrelationships of the various macrominerals. There is accumulating evidence that shows that different concentrations of Na, Cl, and K may interrelate and affect lactational performance. Many times the naturally occurring concentrations of one or more of these elements may have to be associated with varying concentrations of the others in order to optimize animal performance and health. Much experimentation likely will examine these interrelationships in the future. Supplementation of trace elements in diets of dairy cattle is common practice. This

    Modern technologies play a very important role in our lives. It is hard to imagine how people can get along without personal computers, and companies - without powerful computer centers. Nowadays, many devices make modern medicine more effective. Medicine is developing constantly, so introduction of robots in this sector is a very promising activity. Advances in technology have influenced medicine greatly. Robotic surgery is now actively developing worldwide. Scientists have been carrying out research and practical attempts to create robotic surgeons for more than 20 years, since the mid-80s of the last century. Robotic assistants play an important role in modern medicine. This industry is new enough and is at the early stage of development; despite this, some developments already have worldwide application; they function successfully and bring invaluable help to employees of medical institutions. Today, doctors can perform operations that seemed impossible a few years ago. Such progress in medicine is due to many factors. First, modern operating rooms are equipped with up-to-date equipment, allowing doctors to make operations more accurately and with less risk to the patient. Second, technology has enabled to improve the quality of doctors' training. Various types of robots exist now: assistants, military robots, space, household and medical, of course. Further, we should make a detailed analysis of existing types of robots and their application. The purpose of the article is to illustrate the most popular types of robots used in medicine.

    Magnesium, often confused with last month’s mineral of the month manganese, is valued primarily because of its light weight and high strength-to-weight ratio. Magnesium is the eighth most abundant element and constitutes about 2 percent of the Earth’s crust. It is the third most plentiful element dissolved in seawater, with a concentration averaging 0.13 percent. Magnesium is found in over 60 minerals, and also is recovered from seawater, wells, and lake brines and bitterns.

    Sparse, granular inclusions of early-formed minerals found within the Little Glass Mountain rhyolite flows in northern California are shown to provide a means of characterizing the physical conditions, at depth, beneath the Medicine Lake Highland during the latest phase of volcanic activity. Mineral compositions, in combination with thermodynamic calculations and experiments, suggest crystalization at a pressure of 5,200 bars within a 966-836 C temperature range; implying that mineral segregation and equilibration occurred at a depth of 15-18 km beneath the surface. In addition, mass balance calculations indicate that the Medicine Lake flow is a close approximation to the parental magma for the latest silicic lavas.

    Enamel is a unique tissue in vertebrates, acellular, formed on a labile scaffolding matrix and hypermineralized. The ameloblasts are epithelial cells in charge of amelogenesis. They secrete a number of matrix proteins degraded by enzymes during enamel mineralization. This ordered cellular and extracellular events imply that any genetic or environmental perturbation will produce indelible and recognizable defects. The specificity of defects will indicate the affected cellular process. Thus, depending on the specificity of alterations, the teratogenic event can be retrospectively established. Advances in the field allow to use enamel defects as diagnostic tools for molecular disorders. The multifunctionality of enamel peptides is presently identified from their chemical roles in mineralization to cell signaling, constituting a source of concrete innovations in regenerative medicine.

    The radiation although has hazardous effects for human health, developing technologies bring lots of usage fields to radiation like in medicine and nuclear power station buildings. In this case protecting from undesirable radiation is a necessity for human health. Heavyweight concrete is one of the most important materials used in where radiation should be shielded, like those areas. In this study, used heavyweight aggregates of different mineral origin (Limonite, Siderite), in order to prepare different series in concrete mixtures and investigated radiation shielding properties. The experimental results on measuring the radiation shielding, the heavyweight concrete prepared with heavyweight aggregates of different mineral origin show that, are useful radiation absorbents when they used in concrete mixtures.

    The Norway spruce (Picea abies), the most important tree species in European forests, is relatively sensitive to salt and does not grow in natural saline environments. Yet many trees are actually exposed to salt stress due to the common practice of de-icing of mountain roads in winter, using large amounts of NaCl. To help develop strategies for an appropriate use of reproductive seed material on reforestation sites, ensuring better chances of seedling survival in salt-affected areas, we have studied the responses of young spruce seedlings to salt treatments. The specific aim of the work was to identify the optimal salt stress biomarkers in Picea abies, using as experimental material seedlings obtained by germination of seeds with origin in seven populations from the Romanian Carpathian Mountains. These responses included general, conserved reactions such as the accumulation of ions and different osmolytes in the seedlings needles, reduction in photosynthetic pigments levels, or activation of antioxidant systems. Although changes in the contents of different compounds involved in these reactions can be associated to the degree of stress affecting the plants, we propose that the (decreasing) levels of total phenolics or total carotenoids and the (increasing) levels of Na+ or K+ ions in Picea abies needles, should be considered as the most reliable and useful biomarkers for salt stress in this species. They all show very high correlation with the intensity of salt stress, independently of the genetic background of the seeds parental population, and relatively easy, quantitative assays are available to determine their concentrations, requiring simple equipment and little amount of plant material.

    Background and aims Co-existing major depression was found to have a negative impact on the diabetes outcome and the quality of life. The aim of the present study was to assess the prevalence of depressive symptoms in Romanian diabetes patients and to identify the risk factors associated with depression. Methods A total of 144 type 2 diabetes patients were included in the study. Five models of presumed predictors were used to assess the risk factors for depressive symptoms, using hierarchical regression analysis. Together with demographics, disease, lifestyle predictors, previous depressive symptoms and diabetes distress were taken into account. Results In our sample the prevalence of depression was 12.6%. Main risk factors for depressive symptoms were previous depressive symptoms which were associated with depression in both Model 4 (β=0.297, p=0.013) and Model 5 (β=0.239, p=0.017) and diabetes distress in Model 5 (β=0.540, p≤0.001). Employment (β =−0.276, p=0.029) and increased number of diabetes complications (β=0.236, p=0.017) became significant when diabetes distress was added to the analysis. Conclusions The overall prevalence of depressive symptoms was found to be in range with the prevalence identified in the literature. Previous depression and diabetes distress were both independently associated with depression, confirming the bidirectional relationship between depression and diabetes distress. Due to the consequences for daily living, screening for diabetes distress and depression should be done in primary care units both by physicians and trained nurses. PMID:27547056

    The aim of the present study was to assess smoking habits as well as attitudes toward smoking cessation counseling among Romanian dental students in order to build an evidence base for further undergraduate curriculum development. A 38-item self-administered questionnaire was delivered to first to sixth dental students enrolled at the University "Lucian Blaga" Sibiu. The questionnaire covered sociodemographics, smoking habits, knowledge concerning health effects, attitudes, and confidence toward smoking cessation counseling. Smoking was reported by 37 % of participants and was more prevalent among clinical (48.98 %) than preclinical (29.58 %) and basic science students (35.93 %). Students' knowledge that tobacco affects general and oral/dental health and knowledge of dental students regarding the smoking and alcohol behavior taken during medical history varied according to academic year and smoking status, but not according to gender. Only 51.1 % of all students agreed or strongly agreed that they were adequately trained to provide tobacco cessation education. 58.6 %, respectively 52.9 %, strongly agreed that is part of their role as a dentist to assist their patients to stop smoking and to prevent patients from starting to use tobacco products, while only 35.8 % believed that smoking cessation counseling provided by a dentist can be effective in helping patients stop smoking. The main determinants of student's attitudes toward smoking cessation counseling were academic year, clinical experience in the dental settings, and knowledge of smoking adverse effects. Dental school should offer adequate training in tobacco dependence and available continuing education in tobacco intervention in aim to encourage oral health care practitioners to have up-to-date information in aim to play their role effectively in the overall smoking cessation and prevention activities.

    Stratocumulus clouds play a critical role in the Earth's climate system due to their spatial and temporal large extent. For this reason, this study aims to highlight the significant differences of microphysical properties of maritime and continental stratus clouds and By using the ATMOSLAB research aircraft were examined aerosol and microphysical properties, as well as the thermodynamics of the marine boundary layer in and around the Black Sea (between Mangalia, N: 43 48' 34,6'', E: 28̊ 35' 25,12'' and Navodari City N: 44̊ 19' 02'', E: 28̊ 36' 55,24''). More than 10 h measurements obtained by a Cloud Aerosol and Precipitation Spectrometer and the HAWKEYE included aerosol, CCN, cloud droplet and drizzle drop concentrations, air temperatures, liquid water content, real time cloud droplet and ice crystals images and marine aerosol measurements above the sea surface. The over 15 flight legs in clouds (minimum altitude 250 m and maximum altitude 4000 m) and the 4 flight legs performed directly above the sea surface (altitude 120 m) from the three flight 30 October 2015 and 23 November 2015 conducted to results that provide evidence of indirect aerosol effects associated with natural variability in the cloud and aerosol characteristics. For a complete understanding of the large-scale context processes maintaining and dissipating the continental and marine stratocumulus clouds information from a Sun Photometer (Eforie, N: 44̊ 04' 30'', E: 28̊ 37' 55'', altitude 40 m) and satellite data were used. The interpretation performed on the in situ (into cloud and below cloud) measured data have shown, as it was expected, differences between microphysical parameters for maritime and continental clouds and their dependence on aerosol concentrations. These presented results of in situ measurements of clouds above the Romanian Black Sea Coast are the first reported, so that more data is needed for an enhanced understanding of the maritime/continental microphysical contrasts in

    Background Here, we investigated the phylogenetic relationships of the HIV-1 subtype F1 circulating in Angola with subtype F1 strains sampled worldwide and reconstructed the evolutionary history of this subtype in Central Africa. Methods Forty-six HIV-1-positive samples were collected in Angola in 2006 and subtyped at the env-gp41 region. Partial env-gp120 and pol-RT sequences and near full-length genomes from those env-gp41 subtype F1 samples were further generated. Phylogenetic analyses of partial and full-length subtype F1 strains isolated worldwide were carried out. The onset date of the subtype F1 epidemic in Central Africa was estimated using a Bayesian Markov chain Monte Carlo approach. Results Nine Angolan samples were classified as subtype F1 based on the analysis of the env-gp41 region. All nine Angolan sequences were also classified as subtype F1 in both env-gp120 and pol-RT genomic regions, and near full-length genome analysis of four of these samples confirmed their classification as "pure" subtype F1. Phylogenetic analyses of subtype F1 strains isolated worldwide revealed that isolates from the Democratic Republic of Congo (DRC) were the earliest branching lineages within the subtype F1 phylogeny. Most strains from Angola segregated in a monophyletic group together with Romanian sequences; whereas South American F1 sequences emerged as an independent cluster. The origin of the subtype F1 epidemic in Central African was estimated at 1958 (1934–1971). Conclusion "Pure" subtype F1 strains are common in Angola and seem to be the result of a single founder event. Subtype F1 sequences from Angola are closely related to those described in Romania, and only distantly related to the subtype F1 lineage circulating in South America. Original diversification of subtype F1 probably occurred within the DRC around the late 1950s. PMID:19386115

  20. Mineral commodity profiles: nitrogen

    USGS Publications Warehouse

    Kramer, Deborah A.

    2004-01-01

    Overview -- Nitrogen (N) is an essential element of life and a part of all animal and plant proteins. As a part of the DNA and RNA molecules, nitrogen is an essential constituent of each individual's genetic blueprint. As an essential element in the chlorophyll molecule, nitrogen is vital to a plant's ability to photosynthesize. Some crop plants, such as alfalfa, peas, peanuts, and soybeans, can convert atmospheric nitrogen into a usable form by a process referred to as 'fixation.' Most of the nitrogen that is available for crop production, however, comes from decomposing animal and plant waste or from commercially produced fertilizers. Commercial fertilizers contain nitrogen in the form of ammonium and/or nitrate or in a form that is quickly converted to the ammonium or nitrate form once the fertilizer is applied to the soil. Ammonia is generally the source of nitrogen in fertilizers. Anhydrous ammonia is commercially produced by reacting nitrogen with hydrogen under high temperatures and pressures. The source of nitrogen is the atmosphere, which is almost 80 percent nitrogen. Hydrogen is derived from a variety of raw materials, which include water, and crude oil, coal, and natural gas hydrocarbons. Nitrogen-based fertilizers are produced from ammonia feedstocks through a variety of chemical processes. Small quantities of nitrates are produced from mineral resources principally in Chile. In 2002, anhydrous ammonia and other nitrogen materials were produced in more than 70 countries. Global ammonia production was 108 million metric tons (Mt) of contained nitrogen. With 28 percent of this total, China was the largest producer of ammonia. Asia contributed 46 percent of total world ammonia production, and countries of the former U.S.S.R. represented 13 percent. North America also produced 13 percent of the total; Western Europe, 9 percent; the Middle East, 7 percent; Central America and South America, 5 percent; Eastern Europe, 3 percent; and Africa and Oceania
