    2000-10-01

    The practising environment in health care is ever changing in both clinical and management areas. Within dentistry, two major changes have occurred with the development of implantology into a sound treatment approach and a burgeoning of dental litigation. There are medico-legal issues that relate to dental implant treatment with which clinicians must become familiar and there are medico-legal implications that impact on risk management by Medical Indemnity Organizations (MDOs) and the indemnity premiums they set for their members. The aim of this paper is to discuss these issues and highlight those areas of significance to clinicians. PMID:11709962

    In obstetric practice, ethical and medico-legal problems centre on the ability of a labouring woman to give truly informed consent. Conflicts can also arise between the best health interests of the fetus and those of the mother. Consent to a procedure can be given by a competent patient who has been properly informed and has shown understanding of the risks,

  6. Medico legal investigations into sudden sniffing deaths linked with trichloroethylene.

    PubMed

    2015-08-01

    Sudden deaths attributed to sniffing trichloroethylene are caused by the abuse of this solvent which produces pleasant inebriating effects with rapid dissipation. In the event of repeated cycles of inhalation, a dangerous and uncontrolled systemic accumulation of trichloroethylene may occur, followed by central nervous system depression, coma and lethal cardiorespiratory arrest. Sometimes death occurs outside the hospital environment, without medical intervention or witnesses and without specific necroscopic signs. Medico legal investigations into sudden sniffing deaths associated with trichloroethylene demand careful analysis of the death scene and related circumstances, a detailed understanding of the deceased's medical history and background of substance abuse and an accurate evaluation of all autopsy and laboratory data, with close cooperation between the judiciary, coroners and toxicologists.

  8. Medico - historical study of "Vis?cik?" (Cholera).

    PubMed

    Prasad, P V V

    2005-01-01

    The Sanskrit word Vis?cik? refers to a condition in which vitiated v?ta d??a causes pain like pricking with a needle over the body. It occurs in a person suffering with aj?rna (indigestion) and its detailed description is available in Ayurvedic literature. This disease has its existence in India since ancient times; it has also been referred in Mah?h?rata and Tripitikas. Its etiology, signs, symptoms, complications, prognosis and treatment etc. as described in Ayurveda may be correlated with the disease Cholera, which is commonly known as "Haiza" in Hindi. In Greek language, the word Cholera means a flow of bile or the bilious disease. Cholera is an acute infectious diarrheal disease, caused by comma bacillus or vibrio cholerae sero groups 01 or 0139. Aretaetus, Benjamin Rush, Chadwick, John Snow, Robert Koch, etc. were some of the pioneers in Cholera research. Medico- historical importance of Cholera, its transmission, description and references from Ayurvedic texts etc., are being presented in this article. PMID:17333658

    A Pilot Study was performed at the Rehabilitation and Research Centre for Torture Victims (RCT) in Copenhagen in order to explore the possibilities for adding a medico-legal documentation component to the rehabilitation of torture victims already taking place. It describes the process and results on implementing medico-legal documentation in a rehabilitative setting. A modified version of the Guidelines in the Istanbul Protocol was developed on the basis of the review of literature and current practices described in "Documentation of torture victims, implementation of medico-legal protocols". The modified guidelines were tested on five clients. The aim was twofold: 1) To assess the client's attitude towards the idea of adding a documentation component to the rehabilitation process and: 2) To assess the practical circumstances of implementing the Istanbul Protocol in the everyday life of a rehabilitation centre. Results show that all five clients were positive towards the project and found comfort in being able to contribute to the fight against impunity. Also, the Pilot Study demonstrated that a large part of the medico-legal documentation was already obtained in the rehabilitation process. It was however not accessible due to lack of systematization and a data registering system. There are thus important synergies in collecting data for rehabilitation and documentation but a joint database system is necessary to realize these synergies. PMID:19289892

    Finland has one of the highest homicide rates in western Europe but the clear-up rate is also exceptionally high. To create a detailed analysis of homicides (n=161) in a region of western Finland during the 20-year period from 1983 to 2002 all available information was collected retrospectively from multiple sources including medico-legal reports, reports of police investigations, and court proceedings. Among the data collected and analysed were location, time, circumstances, and motives of homicides, forensic pathologists' role at the scene-of-the-crime and in court, autopsy findings, demographics and substance abuse of both victims and offenders, criminal background, forensic psychiatric examinations, and the verdicts of the offenders. A typical homicide was committed without premeditation during the weekend by a drunken male with a knife at hand and with a history of violent crimes. The perpetrator was later found guilty of manslaughter and received a prison sentence. Some noted shortcomings both in the police and the medico-legal investigation procedures are discussed, as well as the forensic pathologist's role in the judicial process in Finland. PMID:17052942

    We examined how Australian telehealth service providers perceived and addressed ethical, medico-legal and clinical governance matters arising from service delivery. Thirty-seven telehealth clinicians and managers were interviewed and a qualitative content analysis was conducted. The services covered six Australian jurisdictions and a range of clinical disciplines. There were 11 medical specialities, surgery, mental health, paediatrics, nursing and allied health. Thirty services (83%) used video consulting and 25 (68%) delivered services to rural areas. Telehealth was reported to be beneficial by reducing adverse events, improving health outcomes, offering increased patient choice of service delivery, and improving access to services for rural areas and home care. There were observations of gains or no change in patient-provider rapport compared to face-to-face communication, with some patients reportedly preferring video. Those interviewed reported some problems with privacy and security, and variable informed consent practices. No examples of malpractice were raised, although there was a common misperception that distant providers were not responsible for clinical care. With respect to clinical governance, telehealth was seen as enabling improved quality, integration and implementation of evidence-based care, and to be a major support for the rural health workforce. Although there were potential ethical, medico-legal and governance problems in Australian telehealth services, these had been easily managed in practice. PMID:22267306

    An exhaustive clinico-biochemical examination of the population of two kishlaks of the Samarkand Region, viz. Karakent (210 persons) and Ishan (248 persons) was carried out. The program of this examination permitted to exclude over 160 forms of hereditary pathology. A total of 45 persons affected with diseases belonging to 12 nosological forms were revealed in the course of the examination. Among the diseases observed only 5 are hereditary sensu stricto, viz. myoclonus-epilepsy, Bonevi-Ulrich's syndrome, imperfect osteogenesis, pigment choreoretinite and Down's syndrome, others belong to diseases with a pronounced hereditary predisposition. The main part of this group comprises neuro-psychic diseases, such as non-differentiated olygophreny (5.0%), epilepsy (1.3%), schizophreny; many of these cases have a familial character, particularly in Karakent. Besides the persons suffering from diseases, 20 heterozygous carriers of beta-thalassemia and 17 heterozygous carriers of G6PD-deficiency were discovered in the kishlaks examined. On the whole the frequency of the diseases revealed did not exceed the level in the general population. Despite the different degree of isolation of the kishlaks examined (Karakent is isolated on a religious basis, F = 0.0064; while Ishan is a desintagrated isolate, F = = 0.0014), no substantial differences between them in the distribution of pathological phenomena were observed. On the basis of the experience of this expedition recomendations are proposed concerning the origination and accomplishment of medico-genetic expeditions. A scheme is proposed for the performance of medico-genetic examination through several stages. The first stage in the composition of tentative maps of the distribution of hereditary diseases within a region on the basis of the information obtained from the medical personnel and from the examination of the documents of district and regional hospitals. Subsequently the primary information is specified, the regions to be examined are determined, as well as concrete tasks and the staff of the expedition. The conclusive stage is the medico-genetic examination proper, including clinical, biochemical, immunological and cytogenetic diagnoses of hereditary pathological phenomena. The place of the disposition is a village or a district hospital. More complicated laboratory studies should be performed on the basis of the institution by which the expedition is formed. The results obtained by such expeditions would be important for the investigation of the problems of genogeography, for the discovery of new forms of mutant alleles, for the investigation of the causes and the conditions of the formation of the definite populational structure, of clinical polymorphism of human hereditary diseases.

    Occupational fatalities are those that occur during the course of a person's occupation. They can occur in any industry or sector. Studies have shown that the construction sector is more dangerous for workers than the industrial sector, and there are more deaths both in the developed and developing countries. The construction sector has seen a boom in countries like India over the past few years and with it an increase in the number of occupational fatalities. Three different types of occupational fatalities pertaining to construction sector are presented here to increase awareness of the different types of occupational fatalities that may occur. The circumstances leading to them are discussed from a medico-legal viewpoint. Specific acts of negligence have been highlighted and suggestions offered with a view to decreasing fatalities.

    Patients undergoing major surgery are at risk for postoperative cognitive dysfunction (POCD). The consciousness of the POCD arises new ethical and medico-legal issues that should be identified, managed and, if possible, prevented. Elderly patients still represent a real challenge for physicians and medical science. This challenge can be surmounted not only through technical progress but also by safeguarding the correct ethical behavior at the base of each relationship between a patient and his physician. Effective communication with the elderly patient is a prerequisite for clear and complete information, involving family members and caregivers when necessary. In every case, the identification of patients with pre-existing risk factors of POCD, shortening the period of time preceding the surgery and a proper technique of the procedure as well as physical and intellectual exercises, nutrition and medication play an important role in decreasing the incidence of neurocognitive deficits in the elderly.

    2004-01-01

    May Sinclair (1863-1946) was one of the first modern novelists to appropriate psychoanalytic theories in her works. She was an early reader of the new psychoanalytic techniques but, rather than embracing its theories wholeheartedly and unquestioningly, she synthesized those that appealed to her own psychology of womanhood. Moreover, Sinclair's position was a unique one. As well as a highly acclaimed novelist with a respected public voice, she was closely associated with the setting up of one of the first psychotherapeutic centres in Britain, the Medico-Psychological Clinic of London. In this paper, I argue that the eclectic psychoanalytic situations in which Sinclair places her literary heroines mirror the eclectic and potentially feminist endeavours of the medico-Psychological Clinic. I draw upon archival material, hitherto unexamined by literary critics and medical historians, to reflect upon the turbulent lifespan of the Clinic and the attempts to curtail its controversial practices.

    Reading a slide and rendering a diagnosis is not only a science but also requires us to appreciate the constant artifact that is introduced in a controlled manner by tissue processing and obtaining a stained tissue section. There are a number of steps involved in getting the final stained tissue section and all these procedures if not performed properly have the potential to give rise to erroneous picture on the slide. Simple errors in judgments can lead to wrong diagnosis and unwarranted treatment. Such mistakes can put us at risk for Medico-Legal problems. The subject of Medico-Legal issues and practice of pathology has been neglected and amount of information available to the practicing professional in India is scarce. This paper focuses on standardized procedures for the various histopathology laboratory exercises. The paper highlights the importance of proper record maintenance with reporting protocols. A list of do's and don’ts for an Oral Pathologist is provided to help him/her in reducing the probable Medico-Legal issues. It does not in any way address the issue of individual competence and diagnostic abilities: That is an aspect for each individual to introspect upon and take remedial action. PMID:24250085

    As we celebrate the 50th anniversary of Gagarin's flight that opened the era of Humans in Space we also commemorate the 30th anniversary of the Space Shuttle Program (SSP) which was triumphantly completed by the flight of STS-135 on July 21, 2011. These were great milestones in the history of Human Space Exploration. Many important questions regarding the ability of humans to adapt and function in space were answered for the past 50 years and many lessons have been learned. Significant contribution to answering these questions was made by the SSP. To ensure the availability of the Shuttle Program experiences to the international space community NASA has made a decision to summarize the medico-biological results of the SSP in a fundamental edition that is scheduled to be completed by the end of 2011 beginning 2012. The goal of this edition is to define the normal responses of the major physiological systems to short-duration space flights and provide a comprehensive source of information for planning, ensuring successful operational activities and for management of potential medical problems that might arise during future long-term space missions. The book includes the following sections: 1. History of Shuttle Biomedical Research and Operations; 2. Medical Operations Overview Systems, Monitoring, and Care; 3. Biomedical Research Overview; 4. System-specific Adaptations/Responses, Issues, and Countermeasures; 5. Multisystem Issues and Countermeasures. In addition, selected operational documents will be presented in the appendices. The chapters are written by well-recognized experts in appropriate fields, peer reviewed, and edited by physicians and scientists with extensive expertise in space medical operations and space-related biomedical research. As Space Exploration continues the major question whether humans are capable of adapting to long term presence and adequate functioning in space habitats remains to be answered We expect that the comprehensive review of the medico-biological results of the SSP along with the data collected during the missions on the space stations (Mir and ISS) provides a good starting point in seeking the answer to this question.

    A?vattha (Ficus religiosa Linn.) is a tree which has got mythological, religious and medicinal importance in Indian culture since ancient times. As per Vedic Index A?vattha means horse stand, a place or site or an object where or under which horses stand. A?vattha is also known as Pipal and Bodhidrma. This tree is the oldest depicted tree in India. In Vedic times it was used to make fire by friction and considered sacred. Atharvav?da associates it with the third heaven. It discusses medicinal properties of A?vattha along with Soma and Ku?tha. A?vattha is associated with the triad of Gods-Brahma, vi??u and siva. Reference to A?vattha is found in R?m?ya?a, Mah?bh?rata, Bhagavadg?ta, Buddhistic literature, Artha??stra, Pur?n?s, Upani?ads etc. non-medical literature also. According to Ayurv?da it has several synonyms. Most of them symbolize its sacredness. A?vattha is useful in various ailments like consumption, vomiting, ulcers in oral cavity, burns, gynaecological problems etc. Thus its medico-historical importance, regional nomenclature, morphological features in brief etc. are being presented in this article with few illustrations.

    The article presents the analysis of knitted trauma to the hyoid bone and laryngeal cartilages, revealed while searching for fresh fractures of the laryngopharynx skeleton for medico-legal purposes. Neck organocomplexes (n = 440) were completely prepared after fixation in formalin. Old injuries were found in 17.3% of cases, and in 3.2% of cases two elements of the complex were formerly broken. More often there was consolidated trauma to the thyroid (11.4% of cases) and cricoid cartilages (7.3%) and, rarely, to the hyoid bone (1.6%) and cervical part of the trachea (0.2%). These injuries occurred twice as often in men (20.3% of cases) than in women (P < 0.01). Substantiated conclusions are: (1) people of working age are most prone to neck trauma; and (2) from the 1960s the percentage of such traumas in the St. Petersburg region has grown due to urbanization. This article presents data on the localization and morphology of the injuries, as well as a review of symptoms and the course of blunt neck trauma. Despite the difficulties associated with the complete regeneration of injured tissues, forensic pathologists can obtain certain information which police officials may be interested in. PMID:10581721

    Medico-economical use of the medical record: the title encloses two different notions which represent two different trends within medical informatics. The first trend is worried about weighting aspects of health resources consumption, mainly about hospital acute care; their key-words are "DRG (Diagnostic Related Groups), Case-Mix, reimbursement by pathology, measurement of indicators (severity or outcome), costs". The other trend is looking for deeper understanding of the medical process and for better diffusion of relevant information helping the day-to-day care process; they speak of "CPR (Computerized patient record), full text reports and corresponding retrieval, detailed data, medical records on Internet, large access to literature and databases". It is mandatory to realize a bridge between these two trends for facing the information technology revolution entering into a self-revolutioning medicine. The purpose of this paper is to begin this bridge by showing what the DRG people expect from the CPR people and what the latter should receive from the former. PMID:10179589

    The aim of this study was the medico-economic evaluation of the closure of ostium secundum type interatrial communications in 32 patients, treated by cardiac catheterisation (group A: n = 17) or by surgery (group B: n = 15). The success rate was 100% with the 2 techniques. With national cost scale data we evaluated the overall cost of the 2 treatments using the information system medical program, starting from homogenous groups of patients: 150 catheterisation, 169 and 170 surgery. As the value for the homogenous group of 150 patients was much lower than the price of the material used for catheterisation, an adjusted group of 150 patients including the price of this material was created. An evaluation in terms of an artificial index of activity was also performed. The average duration of hospital stay for group A was reduced by 6.1 days compared to group B (p < 0.001). The overall cost was lower in group A than in group B (p < 0.001), using the real and "adjusted" homogenous group of 150 patients, with a respective reduction of 7,582 Euros and 3,731 Euros. Surgery and catheterisation scored 8,167 points (17,756 Euros) and 2,726 points (5,926 Euros) per patient respectively on the artificial activity index. In conclusion, catheterisation reduced the duration of hospital stay and brought an economic benefit for the Assurance Maladie compared to surgery. However, surgery is more profitable for the hospital than catheterisation because of the high cost of the prosthesis, which is not taken into account with a homogenous group of non-specific patients. This could hamper the development of this innovative technique in a hospital subjected to overall budgetary constraints. PMID:12838843

    The Italian Paolo Zacchia (1584-1659) is considered one of the fathers of forensic medicine. From a letter sent by the physician and botanist Pietro Castelli, the article seeks to reconstruct the opinions that Zacchia expressed about monsters in his monumental Quaestiones Medico-Legales. Although he did not seem too sure about the possibility that a hybrid could be born from the union of a man and a beast, he believed that God intervened, allowing the birth so that the abomination could be discovered. The opinion of Zacchia is related to the image that people had at the time of the relationship between humans and animals. PMID:25702383

    This article is an exploration of the visualization of sexual assault in the context of adult women. In investigating the production of visual evidence, we outline the evolution of the specialized knowledge of medico-legal experts and describe the optical technologies involved in medical forensic examinations. We theorize that the principles and practices characterizing medicine, science and the law are mirrored in the medico-legal response to sexual assault. More specifically, we suggest that the demand for visual proof underpins the positivist approach taken in the pursuit of legal truth and that the generation of such evidence is based on producing discrete and decontextualized empirical facts through what are perceived to be objective technologies. Drawing on interview and focus group data with 14 sexual assault nurse examiners (SANEs) in Ontario, Canada, we examine perceptions and experiences of the role of the visual in sexual assault. Certain of their comments appear to lend support to our theoretical assumptions, indicating a sense of the institutional overemphasis placed on physical damage to sexually assaulted women's bodies and the drive towards the increased technologization of visual evidence documentation. They also noted that physical injuries are frequently absent and that those observed through more refined tools of microvisualization such as colposcopes may be explained away as having resulted from either vigorous consensual sex or a "trivial" sexual assault. Concerns were expressed regarding the possibly problematic ways in which either the lack or particular nature of visual evidence may play out in the legal context. The process of documenting external and internal injuries created for some an uncomfortable sense of fragmenting and objectifying the bodies of those women they must simultaneously care for. We point to the need for further research to enhance our understanding of this issue. PMID:18952339

    The report presents a medico-legal and toxicological analysis of cases of drowning. Within eleven years, 184 cases of deaths by drowning were observed in our Department. The majority of victims died because of a tragic accident, while in three cases death was a result of suicide. Toxicological observations showed that most victims were under the influence of alcohol. In isolated cases, blood carboxyhemoglobin and delta9tetrahydrocanabinnol were detected. PMID:19441683

  12. Death after an accidental fall of a 101 year old hospitalized patient. Medico-legal implication of falling in geriatrics

    PubMed Central

    2012-01-01

    Background The case presented by the authors gives the opportunity to discuss the medico-legal issues related to lack of prevention of falls in elderly hospitalized patients. Case presentation A 101 year old Caucasian female was admitted to a surgery division for evaluation of abdominal pain of uncertain origin. During hospitalization, after bilateral bed rails were raised, she fell and reported a femoral fracture. Before surgical treatment of the fracture, scheduled for the day after injury, the patient reported a slight reduction in hemoglobin. She received blood transfusion but her general condition suddenly worsened; heart failure was observed and pulseless electrical activity was documented. The patient died 1 day after the fall. Patient relatives requested a judicial evaluation of the case. The case was studied with a methodological approach based on the following steps: 1) examination of clinical records; 2) autopsy; 3) evaluation of clinicians’ behavior, in the light of necroscopic findings and a review of the literature. Conclusions The case shows that an accurate evaluation of clinical and environmental risk factors should be always performed at the moment of admission also in surgery divisions. A multidisciplinary approach is always recommended also with the involvement of the family members. In some cases, as in this one a fall of the patient is expectable but not always avoidable. Physical restraint use should be avoided when not necessary and used only if there are no practical alternatives. PMID:23173622

    This was a prospective study of the modalities of return to work in a male population of 128 patients (mean age 48.9 years)) admitted for cardiovascular rehabilitation after acute infarction or coronary bypass surgery and followed up for 7 years. At one year, 78.9% of the population had returned to work (average delay 126 +/- 97 days), usually to the same job (66.3%) after adaptation (25.8%) or professional reconversion (7.9%). After 3 and 7 years follow-up, the active population was 62.5% and 40.7% respectively and the main reason for definite stopping work was retirement (63%). Temporary stoppages were short (4.5 days and 8.2 days per patient per year at 3 and 7 years respectively), illustrating the good quality of professional rehabilitation. The factors influencing return to work during the first age were young age (47.5 versus 52.7 years) and negative exercise stress tests (83% versus 59% in cases of positive tests, p < 0.05). This study and a review of the literature were used to undertake a medico-economic analysis which showed decreased economic consequences in patients referred for rehabilitation: over 5 years in a group of 100 patients, an economy of 5,818 KF after myocardial infarction or 2,677 KF after coronary bypass surgery was demonstrated. The reasons for these economies were the reduced direct (hospital admissions) and indirect costs (social security reimbursement for off-work and invalidity pensions). Those favourable results underline the value of a consultation of professional aptitude in all programmes of cardiovascular rehabilitation. PMID:10975030

    The second part of this paper1 explores deepening doubts about pyromania as a special insanity, British debates post-1890, and pyromania’s supplanting with the broader diagnostic category of insane incendiarism. It assesses the conceptual importance of revenge and morbid-motivations for arson, and the relationship of Victorian and Edwardian concepts of arson to more modern psychiatric research. The main objective is to ascertain the extent to which Victorian and Edwardian medico-psychologists and medical legists arrived at meaningful and workable definitions of criminal insanity linked to arson. It concludes by emphasizing the limitations, contentiousness and inconsistencies in the use of technical terms such as ‘pyromania’, contrasted with the qualified success of authorities in arriving at more viable and broadly acceptable explanations of insane firesetting.

    This report is a second one in a series of works devoted to the medico-genetical screening of Uzbekistan populations. The paper comprises the results of the analysis of the populational structure of one of the village councils (soviets) of the Urgut District of the Samarkand Region. The main parameters of the population studied were as follows: total number 1529 persons, the average number of inhabitants of one village--328. The proportion of the inhabitants studied--56%, the average number of persons per family--5.22; the average period between subsequent generations--30-35 years, the gametic index--0.8, the inbreeding coefficient inferred from pedigrees--0.018899--0.00781, Fst = 0.03577, the average genetic distanse according to Edwards--0.0231-0.0671. The distribution of Mendelian markers (ABO, Rh, Hp and Ptc) was studied. The observed ratio between a high degree of inbreeding and a relatively low extent of isolation of populations permits to explain satisfactorily the distribution and frequencies of hereditary pathology in the Urgut District of the Samarkand Region pointed out in the previous report.

    Medical malpractice results from inadequate professional knowledge, incompliance to the present state of medical knowledge or negligence and inattention. The aim of the paper was the analysis of medical malpractice cases based on material in the field of neurology. The cases were assessed according to the number and type in 32 medico-legal opinions issued by specialist teams of forensic medicine and neurology in the Department of Forensic Medicine, Medical University of Bia?ystok in the years 2001-2006. In 11 cases (34%) medical malpractice was concluded with reference to improper treatment after head injury or brain pathology, inadequate care at neurology unit, lacked or delayed diagnostics of head pathology and injury, non-referral to hospital by neurologists. In the material analysed diagnostic errors predominated. Majority of them originated from the open health care system. Incompetence of neurologists with regard to differential diagnostics resulting in misdiagnosis and improper therapy was noted. In one third of the overall cases medical malpractice was concluded. The most common causes included misinterpretation of disease signs and symptoms, misapplication of available diagnostic potential and unjustified delay before commencing diagnostics. PMID:20143678

    Tuberculosis is a diffusive infectious disease whose typical behaviour differentiates it from other infectious diseases spread by human-to-human transmission (flu, chicken pox, cholera, etc.) that follow a classic epidemic pattern. Indeed, in the presence of a known source of Koch bacilli that is capable of spreading the bacteria by air, not all exposed individuals inhale the bacteria, not all those who inhale them absorb them, not all those who absorb the bacteria are unable to eliminate them, not all who are able to eliminate them do so using delayed hypersensitivity, not all those who react with delayed hypersensitivity suffer lasting tissue damage (among other things, minor), not all who suffer tissue damage have anatomical sequelae, and not all those who have anatomical sequelae, however minimal, become carriers of bacilli in the latent period. The vast majority (90–95%) of the latter – which are in any case a portion, not the totality of those exposed – remain asymptomatic throughout their lives and never develop active tuberculosis. Based on these biological characteristics and the legal concepts of “epidemic” and “disease,” it becomes highly problematic, if not impossible, to assert both that tuberculosis can cause events of sufficient magnitude to be associated with the crime of “epidemic,” and that the mere diagnosis of a latent tuberculosis infection is sufficient to assume the presence of an illness legally prosecutable in criminal proceedings or a disability prosecutable in civil proceedings. Furthermore, clinically apparent tuberculosis is a temporarily—and in some cases permanently—disabling condition, and in certain work environments, even with the difficulties caused by the lack of available effective diagnostic tools and the insidious behaviour of the disease in the early stages, targeted monitoring to identify other persons who may become ill is appropriate.

    Fasting during the month of Ramadan is obligatory for all adult Muslims with few exceptions. The person observing a fast does not eat, drink, and smoke from dawn to dusk. Google and Medline search was undertaken for the articles related to basic rules of fasting-religious and medical perspectives in the previous 24 years using following key words: Islamic fasting, fasting and diabetes, fasting and endocrine system. There are clear cut guidelines regarding fasting in healthy people and exemptions have been emphasized. Some alterations in pulmonary, cardiac, gastrointestinal and neuropsychiatric systems are observed which do not harm a normal person. A risk strategy has been devised for people with diabetes regarding management during Ramadan fasting. Rules regarding adherence to fasting and concessions during the month of Ramadan are clear. Minor alterations in different body systems are observed in normal people during Ramadan. PMID:26013776

    The functioning of the Regional Review Boards of Ontario (RRB) or their equivalents in other provinces has not been previously reviewed. This study reviews socio-demographic and clinical data of 248 patients seen between 1974 and 1983 by the RRB. The RRB heard 132 applications as 116 were withdrawn. The results are compared with 173 matched inpatient controls. Applications by psychiatrists were infrequently withdrawn or revoked. Long delays between the time of application and the hearing, and a trend towards increasing numbers of applications were noted. Schizophrenia and affective disorder were the most prevalent diagnosis with alcohol abuse and organic brain syndrome being less common among applicants. An increase in duration of stay and transfer to chronic care institutions were found among applicants. Results suggest that RRB's are not 'rubber stamping bodies' and should be more readily available and should have increased public accountability. Future changes to the Mental Health Act should be based on scientific data. PMID:3779592

    Plant products may be alternative sources of mosquito larval control agents, since they constitute a rich source of bioactive compounds that are biodegradable into nontoxic products. It has been reported that quinones and derivatives present toxic activity against mosquito larvae Aedes aegypti. Therefore, these facts led us to investigate the larvicidal potential of six structurally related para-benzoquinones against A. aegypti L. (Culicidae) larvae, the vector of dengue fever. All the para-benzoquinones were found to have larvicidal effect. The unsubstituted para-benzoquinone was the compound that exhibited the lowest potency, while 2-isopropyl-para-benzoquinone was the most bioactive. In general, the presence of alkyl groups results in more potent compounds. In addition, the number, position, and size of these groups modulate the potency of the compounds. The experimental results showed that by appropriate structural modification of para-benzoquinones, it may be possible to develop novel insecticidal compounds with potential use to control A. aegypti population.

    Tens to hundreds of micrometers long organic nanofibers have been generated from methoxy functionalized quaterphenylene molecules. The mutual alignment of the fibers is similar to that of previously reported nanofibers from para-hexaphenylene, and they emit intense, blue light centered at 400 nm with well resolved higher order vibronic peaks. The morphology is slightly different from that of para-hexaphenylene nanofibers, reflecting the different molecular structure. This study demonstrates that it is possible to generate organic nanofibers from artificially functionalized molecules and thus opens up the route to dedicated applications in new microdevices.

    Quantum-mechanical close-coupling calculations have been performed on rotational energy transfer in collisions of para-ammonia with ground-state (j = 0) para-hydrogen. Rate coefficients are given for the temperature range T = 15-300 K. The calculations employed an ab initio potential energy surface derived from separate determinations of the SCF and dispersion energies. The MOLSCAT computer package was used to perform the scattering calculations. Comparison is made with the recent results of Billing and Diercksen (1985 and 1986), who adopted a semiclassical approach as well as a different potential. Conclusions on the accuracy of the potential surface are drawn from comparison with experimental microwave double resonance and pressure broadening work. The extent to which He behaves like ground-state para-He in collisions with NH3 is also investigated.

    India is a signatory to the UN backed Consumer Protection Resolution, and has enacted the Consumer Protection Act in 1986 to promote and protect the rights of consumers. A land-mark judgment of the Supreme Court of India in 1996, has paved the way for a number of lawsuits involving the public sector, including an eminent tertiary care medical institution. The case described in this study was filed with the State Consumer Dispute Redressal Commission in June 2000. The complainant was a fifty year old female who noticed a lump in her right breast; which was diagnosed as malignant by fine needle aspiration cytology (FNAC); and was treated by surgery and adjuvantradio-therapy (brachytherapy). Subsequently, the tissue sent for histo-pathological study was reported to be 'benign phyllodes tumour'; which was confirmed by other centres in India and the UK. The complaint filed for total damages amounting to Rupees 19 lacs (approx. 27,300 UK pounds) along with interest from the date of operation. Review of the relevant literature suggests that phyllodes tumour of the breast has various sub-types;and even borderline cases can develop malignancy at a later date. It is also clear that false positive cases had been reported previously in cases diagnosed by FNAC. Finally, avenues to minimise litigation through in-house mechanisms and a new concept of mediation have been explored. PMID:12437194

    In principle, all surgical interventions should only be carried out if the surgeon can show that he/she has actually received training for the intervention. However, the most important factor is probably the surgical information sheet signed by the patient and the consent form. Preoperative photo documentation can be very important and should be compiled before any cosmetic surgery and, if possible, before all other operations too. In the event of a lawsuit, the surgeon should initially remain calm and refrain from making any rash admissions of guilt, certainly not in writing. In the worst case, this might mean that the surgeon's liability insurer is not obliged to settle a claim. PMID:19536512

    Fetal laceration is a recognized complication of caesarean delivery. The aim of this study was to investigate the incidence, type, location, risk factors and long-term consequences of accidental fetal incised wounds during caesarean delivery. During a five-year period, we observed 25 cases of fetal lacerations caused by the scalpel during hysterotomy. In 20 of these cases, we observed these lesions as consultants for the Neonatologic Care Unit; the other five cases came under our care after an insurance claim for damages against the gynaecologist. All the infants had a lesion located to the head. In only 5 of the 25 cases the lesion was reported in the operative summary, and only 16 of the 25 mothers had signed an informed consent before surgery. With regard to the 20 cases diagnosed at the Neonatologic Care Unit, the lesion was closed using single stitches in nine cases, and with biological glue in 11 cases. Concerning the five cases that underwent legal proceedings against the gynaecologist, a clinical examination was performed by an expert in Public Health and Social Security in collaboration with a paediatric surgeon to evaluate the degree of biological damage. In all five cases, the result of the legal challenge was monetary compensation for the physical and moral damage caused by the gynaecologists to the patients and their parents. Accidental fetal lesions may occur during caesarean delivery; the incidence is significantly higher during emergency caesarean delivery compared to elective procedures. Patients should sign an informed consent in which they should be informed about the risk of the occurrence of fetal lacerations during caesarean delivery in order to avoid legal complications.

    Ichthyosis fetalis or Harlequin ichthyosis is an extremely severe and fatal hereditary skin disorder with an autosomal recessive inheritance. It is distinctive because of its remarkable clinical appearance which includes epidermal keratinization, hypoplasia of fingers or nails, malformation of ear and nose and incompatibility with life. This report describes a case of Harlequin ichthyosis along with detailed autopsy findings, which manifested the suspended animation in the early hours after delivery and showing a peculiar malformation of the cerebral hemispheres. To the best of the knowledge, this may be the first report of Harlequin ichthyosis in the forensic literature describing mal development of cerebral hemispheres and suspended animation in a case of Harlequin Ichthyosis.

    This study looks at the case of a 20-year-old fisherman, who was speared in the head, the spear entering at his jaw and protruding from the top of his scull, while he was swimming unaccompanied; he was rescued, admitted to the intensive care unit for an operation, remained in a coma for a few days and then had a full recovery. About 10 days before the rescue, he had visited a monk who, intuited and functioning as channel of the divine spirit, had told him that he 'should not be afraid of anything', rubbing the top of his scull and his jaw exactly at the points through which the 40-inch spear passed. After the incident, the monk prescience again the exact day on which he would recover from the coma. It is concluded that the survival of the fisherman can be attributed to a paranormal event. The monk's prescience permit the assumption that a divine spirit was pervasive throughout the universe and present in this life-threatening situation, endeavouring to assist the lifeguard, the neurosurgeons and the young fisherman.

    Perechocky, Andrew

    2014-12-01

    Medical collaboration with authoritarian regimes historically has served to facilitate the use of torture as a tool of repression and to justify atrocities with the language of public health. Because scholarship on medicalized killing and biomedicalist rhetoric and ideology is heavily focused on Nazi Germany, this article seeks to expand the discourse to include other periods in which medicalized torture occurred, specifically in Argentina from 1976 to 1983, when the country was ruled by the Proceso de Reorganización Nacional military regime. The extent to which medical personnel embedded themselves within the Proceso regime's killing apparatus has escaped full recognition by both scholars and human rights activists. This article reconstructs the narrative of the Proceso's human rights abuses to argue that health professionals knowingly and often enthusiastically facilitated, oversaw, and participated in every phase of the "disappearance," torture, and mass murder process.

    Occupational deaths are work-related deaths and usually occur in the work place of an individual. A case of occupational death in a female factory worker has been described, where the saree she was wearing accidentally got entangled in the moving belt and caused ligature strangulation. She was unconscious throughout indicating bilateral occlusion of the carotids and died a day after the incident. The authors have described the correlation between the distribution of the injuries on the body and the manner a saree is worn. Investigation of the workplace revealed that the place where she was standing was located between two machines, and the space was inadequate for normal movement. Some suggestions have been offered which may decrease the incidences of occupational ligature strangulation due to entanglement of dress materials in the moving machineries. PMID:25882146

    In October 2010 the District Court sitting in Cairns, Queensland, found Tegan Leach not guilty of attempting to procure her own abortion and Sergie Brennan not guilty of supplying Leach with the drugs Mifepristone and Misoprostol to procure an abortion. Brennan obtained the drugs from his sister in the Ukraine through the regular postal system. R v Brennan and Leach was the first case in Queensland's history where a woman was charged with procuring her own abortion. The drugs are accepted by the medical profession worldwide for medical abortions. A prosecution witness gave evidence that Mifepristone is not harmful or injurious to the health of a woman and it is listed as an essential medicine by the World Health Organisation and approved for use by the Australian Therapeutic Goods Administration. The jury found the defendants not guilty because they were not satisfied beyond reasonable doubt that the combination of the drugs Mifepristone and Misoprostol was a "noxious" substance under the Criminal Code (Old). This article concludes that there is no regulatory miracle which will stop the traffic of Mifepristone and Misoprostol into Australia and therefore an intelligent regulatory response is required which would make it unnecessary for women to seek Mifepristone and Misoprostol from overseas networks and the internet. Among other things, this would include the repeal of confusing, inappropriate and ineffective abortion laws. PMID:21528743

    Intimate partner violence (IPV) is a significant worldwide problem whose magnitude and risk factors vary across different settings and cultures. Nowadays, it is a priority to improve the knowledge on this issue in order to formulate better evidence-based policy responses. This study aims to contribute to a better understanding of non-fatal IPV against women in Spain. A retrospective analysis of IPV cases with a final judicial decision was carried out. The period under study extended from January 2005 to December 2012, with a total of 582 files included in the investigation. Most IPV victims were young adult women of Spanish origin, either married or single, with children, unemployed and with a low family income level. The majority of alleged perpetrators were young adults, employed, with a middle-low income level, a history of alcohol consumption/abuse, but no criminal records. Most victims had previous history of IPV, were engaged in a long-term relationship with their abuser and lived with him at the time of assault. The combination of psychological and physical abuse was the most frequent form of violence. The most common mechanisms of assault consisted in minor acts of physical violence, which resulted in mild injuries, most of them in the upper limbs and face. Nearly half of women sought medical care, but physician's injury report was only made in about a quarter of these cases, even though it is mandatory for health professionals. The majority of criminal proceedings were initiated by the victim's report and ended in conviction, most of them being considered occasional mistreatment. This study confirms the heterogeneity of the phenomenon of intimate partner violence. The importance of adopting standard IPV concepts and promoting the recognition and assessment of this form of violence amongst health care professionals, criminal investigators and forensic personnel is emphasized.

    Em 2002 o ensino de Astronomia foi proposto como um dos temas estruturadores pelos Parâmetros Curriculares Nacionais e sugerido como facilitador para que o aluno compreendesse a Física como construção humana e parte do seu mundo vivencial, mas raramente seus conceitos foram ensinados. A presente pesquisa discute dois aspectos relacionados à abordagem de Astronomia. O primeiro aspecto é se ela está sendo abordada pelos professores do Ensino Médio e o segundo, aborda a maneira como ela está sendo ensinada. Optou-se pela aplicação de um questionário a partir do 2° semestre de 2006 e durante o ano de 2007 com professores que ministram a disciplina de Física, os quais trabalham em escolas estaduais em Rio Grande da Serra, Ribeirão Pires e Mauá no estado São Paulo. Dos 66,2% dos professores que responderam ao questionário nos municípios de Rio Grande da Serra, Ribeirão Pires e Mauá, 57,4% não aplicaram nenhum tópico de astronomia, 70,2% não utilizaram laboratório, 89,4% não utilizaram qualquer tipo de programa computacional, 83,0% nunca fizeram visitas com alunos a museus e planetários e 38,3% não indicaram qualquer tipo de livro ou revista referente à astronomia aos seus alunos. Mesmo considerando a Astronomia um conteúdo potencialmente significativo, esta não fez parte dos planejamentos escolares. Portanto são necessárias propostas que visem estratégias para a educação continuada dos professores como, por exemplo, cursos específicos sobre o ensino em Astronomia.

    2015-06-18

    The photolysis of para-methoxyphenyl pentazole (MeOPP) in methylcyanide (MeCN), investigated in the far UV (FUV) and near UV (NUV) is compared with the photolysis of para-methoxyphenyl azide (MeOPA). The main photoproduct of MeOPP is MeOPA, which, due to further photon absorption, yields mostly 4,4'-dimethoxyazobenzene as the final thermally stable product. The overall product quantum yield of both MeOPP and MeOPA is about 0.5 due to competition with internal conversion (IC) to S0 implying ultrafast nonreactive processes. Both pentazole and azide yield only 4,4'-dimethoxyazobenzene (trans and cis isomers, trans first) upon FUV photolysis in dilute solutions, whereas in the NUV, though the azo isomers are still the major products, other species are also formed. The yields of these products are 17% and 10% for the azide and the pentazole, respectively. The difference in yield indicates pentazole photoreactions that do not proceed via the azide. The products observed upon NUV photolysis may be the precursors of tars commonly produced in azide photochemistry. The exclusive production of azo compounds in the FUV indicates a rapid route to the triplet nitrene, generally considered to be the precursor of azo products. PMID:25660194

    1997-01-01

    Steady state photoconduction was studied in optically thin spin coated and optically thick solution grown films of an oligo-para-phenylenevinylene sandwiched between indium tin oxide (ITO) and aluminum (Al) contacts. Oligomers represent model systems for polyphenylenevinylene that do not contain structural irregularities and impurities always present in polymers. Upon irradiation through the positively biased ITO contact, dissociation of excited states via electron transfer to the ITO prevails. It leads to a field and temperature dependent photocurrent that is symbatic with the absorption spectrum. The efficiency of this process increases with excess energy of the primarily excited state. Photocurrents due to bulk photoionization are observed upon irradiating through the positively biased Al contact. They result from temperature and field assisted dissociation of geminate e-h pairs generated either by field induced break-up of molecular singlet states or by direct charge transfer transition.

  12. Towards a double field theory on para-Hermitian manifolds

    2013-12-15

    In a previous paper, we have shown that the geometry of double field theory has a natural interpretation on flat para-Kähler manifolds. In this paper, we show that the same geometric constructions can be made on any para-Hermitian manifold. The field is interpreted as a compatible (pseudo-)Riemannian metric. The tangent bundle of the manifold has a natural, metric-compatible bracket that extends the C-bracket of double field theory. In the para-Kähler case, this bracket is equal to the sum of the Courant brackets of the two Lagrangian foliations of the manifold. Then, we define a canonical connection and an action of the field that correspond to similar objects of double field theory. Another section is devoted to the Marsden-Weinstein reduction in double field theory on para-Hermitian manifolds. Finally, we give examples of fields on some well-known para-Hermitian manifolds.

  14. Construction of a Para-Ortho Hydrogen Test Cryostat

    NASA Astrophysics Data System (ADS)

    Essler, J.; Haberstroh, Ch.

    2010-04-01

    In a prospective hydrogen economy it is necessary to verify the para concentration of the employed hydrogen. In case of a short storage time of about a few days only it has been shown that a partial conversion into para-hydrogen gives an optimized overall efficiency. Hence, an easy and reliable method of measuring the para-hydrogen concentration is needed. In this paper, the concept and construction of a small test cryostat are described and first results are presented. The measuring principle is based on a catalytic induced adiabatic ortho-para conversion of a hydrogen gas flow starting from a known temperature. The operation of the system only requires a certain amount of liquid nitrogen as coolant. To determine the concentration of para-hydrogen it is only necessary to measure the temperature of the gas before and after the adiabatic catalyst cell. The measuring cryostat is used for further investigation of the spontaneous para-ortho conversion in the supercritical state. In addition, the design of the cryostat allows the investigation of different catalyst materials regarding the catalytic activity and possible degradation by using a known para concentration for the measurement.

    The determination of the dissociative recombination rate coefficient of H3+ has had a turbulent history, but both experiment and theory have recently converged to a common value. Despite this convergence, it has not been clear if there should be a difference between the rate coefficients for ortho-H3+ and para-H3+. A difference has been predicted theoretically and could conceivably impact the ortho:para ratio of H3+ in the diffuse interstellar medium, where H3+ has been widely observed. We present the results of an experiment at the CRYRING ion storage ring in which we investigated the dissociative recombination of highly enriched (˜83.6%) para-H3+ using a supersonic expansion source that produced ions with Trot˜60-100 K. We observed an increase in the low energy recombination rate coefficient of the enriched para-H3+ by a factor of ˜1.25 in comparison to H3+ produced from normal H2 (ortho:para=3:1). The ratio of the rate coefficients of pure para-H3+ to that of pure ortho-H3+ is inferred to be ˜2 at low collision energies; the corresponding ratio of the thermal rate coefficients is ˜1.5 at electron temperatures from 60 to 1000 K. We conclude that this difference is unlikely to have an impact on the interstellar ortho:para ratio of H3+.

    The cooling capacity of a solid hydrogen cooling system is significantly increased by exposing vapor created during evaporation of a solid hydrogen mass to a catalyst and thereby accelerating the endothermic para-to-ortho transition of the vapor to equilibrium hydrogen. Catalyst such as nickel, copper, iron or metal hydride gels of films in a low pressure drop catalytic reactor are suitable for accelerating the endothermic para-to-ortho conversion.

  13. ParaText : scalable text modeling and analysis.

    SciTech Connect

    2010-06-01

    Automated processing, modeling, and analysis of unstructured text (news documents, web content, journal articles, etc.) is a key task in many data analysis and decision making applications. As data sizes grow, scalability is essential for deep analysis. In many cases, documents are modeled as term or feature vectors and latent semantic analysis (LSA) is used to model latent, or hidden, relationships between documents and terms appearing in those documents. LSA supplies conceptual organization and analysis of document collections by modeling high-dimension feature vectors in many fewer dimensions. While past work on the scalability of LSA modeling has focused on the SVD, the goal of our work is to investigate the use of distributed memory architectures for the entire text analysis process, from data ingestion to semantic modeling and analysis. ParaText is a set of software components for distributed processing, modeling, and analysis of unstructured text. The ParaText source code is available under a BSD license, as an integral part of the Titan toolkit. ParaText components are chained-together into data-parallel pipelines that are replicated across processes on distributed-memory architectures. Individual components can be replaced or rewired to explore different computational strategies and implement new functionality. ParaText functionality can be embedded in applications on any platform using the native C++ API, Python, or Java. The ParaText MPI Process provides a 'generic' text analysis pipeline in a command-line executable that can be used for many serial and parallel analysis tasks. ParaText can also be deployed as a web service accessible via a RESTful (HTTP) API. In the web service configuration, any client can access the functionality provided by ParaText using commodity protocols ... from standard web browsers to custom clients written in any language.

  14. El uso de la neuromodulación para el tratamiento del temblor

    PubMed Central

    Bendersky, Damián; Ajler, Pablo; Yampolsky, Claudio

    2014-01-01

    Introducción: El temblor puede ser un desorden incapacitante y el tratamiento de primera línea para estos pacientes es farmacológico. Sin embargo, este tratamiento puede llevar a una reducción satisfactoria del temblor en sólo el 50% de los pacientes con temblor esencial. La talamotomía era el tratamiento de elección para el temblor refractario al tratamiento médico hasta que comenzó a utilizarse la estimulación cerebral profunda (ECP) del núcleo ventral intermedio (Vim) del tálamo. En la actualidad, raramente se realiza la talamotomía. Métodos: Este artículo es una revisión no sistemática de las indicaciones, resultados, parámetros de programación y técnica quirúrgica de la ECP del Vim para el tratamiento del temblor. Resultados: Aunque los resultados clínicos son similares usando la talamotomía o la ECP del Vim, la primera causa más efectos adversos que la última. Además, la ECP puede ser usada bilateralmente, mientras que la talamotomía tiene un alto riesgo de causar disartria cuando se realiza de ambos lados. La ECP del Vim logró una adecuada mejoría del temblor en varias series de pacientes con temblor causado por temblor esencial, enfermedad de Parkinson o esclerosis múltiple. Además del Vim, hay otros blancos que están siendo usados por varios autores, tales como la zona incerta y las radiaciones prelemniscales. Conclusión: La ECP del Vim es un tratamiento útil para el temblor incapacitante refractario al tratamiento médico. Es esencial realizar una precisa selección de pacientes, así como utilizar una técnica quirúrgica correcta. Aún se desconoce el mejor blanco estereotáctico para el temblor, aunque el Vim es el más usado. PMID:25165613

  15. Rotational excitation of HCN by para- and ortho-H?.

    PubMed

    Vera, Mario Hernández; Kalugina, Yulia; Denis-Alpizar, Otoniel; Stoecklin, Thierry; Lique, François

    2014-06-14

    Rotational excitation of the hydrogen cyanide (HCN) molecule by collisions with para-H2(j = 0, 2) and ortho-H2(j = 1) is investigated at low temperatures using a quantum time independent approach. Both molecules are treated as rigid rotors. The scattering calculations are based on a highly correlated ab initio 4-dimensional (4D) potential energy surface recently published. Rotationally inelastic cross sections among the 13 first rotational levels of HCN were obtained using a pure quantum close coupling approach for total energies up to 1200 cm(-1). The corresponding thermal rate coefficients were computed for temperatures ranging from 5 to 100 K. The HCN rate coefficients are strongly dependent on the rotational level of the H2 molecule. In particular, the rate coefficients for collisions with para-H2(j = 0) are significantly lower than those for collisions with ortho-H2(j = 1) and para-H2(j = 2). Propensity rules in favor of even ?j transitions were found for HCN in collisions with para-H2(j = 0) whereas propensity rules in favor of odd ?j transitions were found for HCN in collisions with H2(j ? 1). The new rate coefficients were compared with previously published HCN-para-H2(j = 0) rate coefficients. Significant differences were found due the inclusion of the H2 rotational structure in the scattering calculations. These new rate coefficients will be crucial to improve the estimation of the HCN abundance in the interstellar medium. PMID:24929383

    2003-08-01

    Em 2001, o Instituto Superior de Ciências Aplicadas (ISCA Faculdades de Limeira) iniciou um projeto pelo qual o Observatório do Morro Azul empreendeu uma parceria com o Centro de Promoção Social Municipal (CEPROSOM), instituição mantida pela Prefeitura Municipal de Limeira para atender crianças e adolescentes carentes. O CEPROSOM contava com dois projetos: Projeto Centro de Convivência Infantil (CCI) e Programa Criança e Adolescente (PCA), que atendiam crianças e adolescentes em Centros Comunitários de diversas áreas da cidade. Esses projetos têm como prioridades estabelecer atividades prazerosas para as crianças no sentido de retirá-las das ruas. Assim sendo, as crianças passaram a ter mais um tipo de atividade - as visitas ao observatório. Este painel descreve as várias fases do projeto, que envolveu: reuniões de planejamento, curso de Astronomia para as orientadoras dos CCIs e PCAs, atividades relacionadas a visitas das crianças ao Observatório, proposta de construção de gnômons e relógios de Sol nos diversos Centros Comunitários de Limeira e divulgação do projeto na imprensa. O painel inclui discussões sobre a aprendizagem de crianças carentes, relatos que mostram a postura das orientadoras sobre a pertinência do ensino de Astronomia, relatos do monitor que fez o atendimento no Observatório e o que o número de crianças atendidas representou para as atividades da instituição desde o início de suas atividades e, em particular, em 2001. Os resultados são baseados na análise de relatos das orientadoras e do monitor do Observatório, registros de visitas e matérias da imprensa local. Conclui com uma avaliação do que tal projeto representou para as Instituições participantes. Para o Observatório, em particular, foi feita uma análise com relação às outras modalidades de atendimentos que envolvem alunos de escolas e público em geral. Também é abordada a questão do compromisso social do Observatório na educação do público em questão.

    Dick, Elliot C. (Tulane University School of Medicine, New Orleans, La.) and William J. Mogabgab. Characteristics of para-influenza 1 (HA-2) virus. III. Antigenic relationships, growth, interaction with erythrocytes, and physical properties. J. Bacteriol. 83:561–571. 1962—Hemagglutination-inhibition tests with rabbit and rooster immune sera showed HA-2-like strains of para-influenza 1 to be nearly as closely related antigenically to para-influenza 3 (HA-1) virus as to the Sendai strain of para-influenza 1; however, convalescent sera from humans infected with para influenza 1 virus exhibited four-fold or greater increases in antibody to HA-2 and Sendai viruses, but seldom to HA-1. Para-influenza 1 (HA-2) infectivity was destroyed within 2 hr at temperatures approaching 50 C; at 36 C, infective virus disappeared by 80 hr. At a temperature of 44 C or below, the hemagglutinin (HA) titer remained unchanged for 100 hr; but at temperatures above this, hemagglutinin was destroyed rapidly. Virus infectivity was found to be most stable at very slightly acid or neutral pH and to be increasingly labile at pH values more extreme than 5.7 and 8.7. Hemagglutinin was generally more resistant than infectivity to extremes of reaction; this was most notable in the alkaline range. In primary monkey-kidney tissue culture, virus was adsorbed in 5 hr, new infective virus was noted in 11 to 15 hr, and maximal amounts were detected at 60 hr and maintained through 132 hr. Production of hemagglutinin paralleled that of infectivity. The tcid50/HA ratio was approximately 4.5. With human type “O” erythrocytes, the HA titer of Copenhagen 222 virus suspensions was raised two- to fourfold by increasing the temperature of reaction and sedimentation from 4 C to room temperature. It could not be demonstrated that this thermal effect was due either to an increased total adsorption at an elevated temperature or to a greater rate of adsorption; the rate of hemagglutination was, however, increased by fourfold at the higher temperature.

    A 19 year old male was admitted to a tertiary care centre in Sri Lanka, with a history of snake bite while sleeping at night. A killed specimen of a snake was brought with the patient. It had been identified as a non-venomous snake by the doctor and handed over to relatives, with a comment to that effect. Patient had no clinical or laboratory evidence of envenoming on admission. Patient developed bilateral ptosis six hours after alleged snake bite, soon followed by respiratory paralysis and was treated with Indian polyvalent anti-venom serum. After 12 h of the bite, patient had developed hypotension that did not respond to ionotropes. Despite intensive management, patient had become deeply comatose and deceased 46 h following the snake bite. Autopsy revealed features suggestive of disseminated intravascular coagulation. Since an allegation of medical negligence too had been levelled by the relations of the patient against the clinical staff, the buried specimen of the snake was recovered by police, on a judicial order, a week later. It was found to be almost completely disintegrated and only the scales and bones were remaining. According to the scale characters, the reconstructed specimen was identified as Indian krait (Bungarus caeruleus). Authentication of snake is important in investigating a death due to snake bite, especially when the snake was initially claimed to be a non-venomous snake. This case suggests the usefulness of forensic identification of species of the snake in investigating suspected snake bite cases. PMID:24237800

    The data of the Institute of Legal Medicine and Insurance of the University of Parma regarding mortal motorcycle, motorbicycle and cycling accidents for a ten year period is cited (1973-1982) (296 cases). The data show a very high incidence of cranio-facial lesions (83.5%) which is the absolute most frequent cause of death (58.5%). The appeal for the promulgation of a rider's helmet as obligatory in Italy thus becomes an urgency. The high percentage of mortal accidents amongst cyclists and the substantial correspondence to the traumatology of motorcyclists senders towards this category of road users the need for similar preventive measures, if these can't be resolved with helmets for practical reasons, it is necessary to solicit more severe and drastic control for the respect of circulation regulations by them. On the other hand it is necessary to take measures capable of guaranteeing a way (lane for cyclists). PMID:2943102

    During the 30-year period 1961-1990, a total of 22 deaths with criminal multilation/dismemberment of the human body were registered in Sweden. The multilations occurred in time clusters, mostly during the summer and winter periods, and increased during the three decades, with incidence rates of 0.05, 0.1, and 0.125 per million inhabitants and year, respectively. Multilation was noted 6.6 times more often in large urban areas than in the rest of Sweden. Defensive mutilation, in order to get rid of the corpse or make its identity more difficult, was noted in ten instances, aggressive mutilation following outrageous overkilling in four, offensive mutilation (lust murder) in seven, and necromanic multilation in one instance. In the last-mentioned case the cause of death was natural, while all deaths in the first three groups were homicidal, or homicide was strongly suspected. All perpetrators were males, in six instances assisted by other persons. In more than half of the cases the perpetrator's occupation was associated with application of anatomical knowledge, e.g., butcher, physician, veterinary assistant, or hunter. The perpetrators of the defensive and aggressive mutilations were mostly disorganized, i.e., alcoholics or drug users with previous psychiatric contacts and criminal histories, while the lust murderers were mostly organized, with a history of violent crimes (including the "serial killing" type), drug abuse and mental disorders with anxiety and schizophrenia, in that order to a diminishing degree. There were differences in mode of mutilation, depending on whether the mutilation was carried out by a layman, a butcher, or a physician. In only one case was the perpetrator convicted for the mutilation act itself; in the remaining instances the manslaughter, as a more serious crime, assimilated the mutilation. When the mutilation made it impossible to establish the cause of death, the perpetrators, despite strong circumstantial evidence indicating murder, were acquitted. PMID:9608692

    2015-01-12

    In this work we tie concepts derived from statistical mechanics, information theory and contact Riemannian geometry within a single consistent formalism for thermodynamic fluctuation theory. We derive the concrete relations characterizing the geometry of the Thermodynamic Phase Space stemming from the relative entropy and the Fisher-Rao information matrix. In particular, we show that the Thermodynamic Phase Space is endowed with a natural para-contact pseudo-Riemannian structure derived from a statistical moment expansion which is para-Sasaki and {\\eta}-Einstein. Moreover, we prove that such manifold is locally isomorphic to the hyperbolic Heisenberg group. In this way we show that the hyperbolic geometry and the Heisenberg commutation relations on the phase space naturally emerge from classical statistical mechanics. Finally, we argue on the possible implications of our results.

The dominant triplet exciton generation mechanism is assigned to nongeminate bimolecular recombination of photogenerated, spin-12 polarons. This process is active within a few hundred femtoseconds after photoexcitation and involves about 20% of the initially excited states. At higher photoexcitation densities, we observe an

    2014-06-01

    When disubstituted benzene molecules are considered the relative position of the substituents must be defined. The three possible forms are ortho-, meta-, and para- where the latter is investigated in this work by consideration of the effect para positioned substituents will have on the vibrational modes. The consistency of the labelling and assignment of the vibrational frequencies of the para disubstituted benzene molecules is investigated in their ground states (S0) and first electronically excited states (S1). The work extends a previously published nomenclature where ring-localised vibrations are compared straightforwardly across different monosubstituted benzene species and given the label Mi. The assignments of the frequencies include previous work but also the calculated wavenumbers for both hydrogenated disubstituted benzenes (-h4) and the deuterated isotopologues (-d4) employing density functional theory (DFT) and time-dependent density functional theory (TDDFT).

  4. Amazon Land Wars in the South of Para

    The South of Para, located in the heart of the Brazilian Amazon, has become notorious for violent land struggle. Although land conflict has a long history in Brazil, and today impacts many parts of the country, violence is most severe and persistent here. The purpose of this article is to examine why. Specifically, we consider how a particular Amazonian place, the so-called South of Para has come to be known as Brazil's most dangerous badland. We begin by considering the predominant literature, which attributes land conflict to the frontier expansion process with intensified struggle emerging in the face of rising property values and demand for private property associated with capitalist development. From this discussion, we distill a concept of the frontier, based on notions of property rights evolution and locational rents. We then empirically test the persistence of place-based violence in the region, and assess the frontier movement through an analysis of transportation costs. The findings from the analyses indicate that the prevalent theorization of frontier violence in Amazonia does little to explain its persistent and pervasive nature in the South of Para. To fill this gap in understanding, we develop an explanation based the geographic conception of place, and we use contentious politics theory heuristically to elucidate the ways in which general processes interact with place specific history to engender a landscape of violence. In so doing, we focus on environmental, cognitive, and relational mechanisms (and implicated structures), and attempt to deploy them in an explanatory framework that allows direct observation of the accumulating layers of the region's tragic history. We end by placing our discussion within a political ecological context, and consider the implications of the Amazon Land War for the environment.

    We report laboratory measurements of the absorption coefficient of solid para-H2, within the wavelength range from 1 to 16.7 ?m, at high spectral resolution. In addition to the narrow rovibrational lines of H2 which are familiar from gas-phase spectroscopy, the data manifest double transitions and broad phonon branches that are characteristic specifically of hydrogen in the solid phase. These transitions are of interest because they provide a spectral signature which is independent of the impurity content of the matrix. We have used our data, in combination with a model of the ultraviolet absorptions of the H2 molecule, to construct the dielectric function of solid para-H2 over a broad range of frequencies. Our results will be useful in determining the electromagnetic response of small particles of solid hydrogen. The dielectric function makes it clear that pure H2 dust would contribute to infrared (IR) extinction predominantly by scattering starlight, rather than absorbing it, and the characteristic IR absorption spectrum of the hydrogen matrix itself will be difficult to observe.

    Objective To identify inhibitors of the essential chromosome partitioning protein ParA that are active against Mycobacterium tuberculosis. Methods Antisense expression of the parA orthologue MSMEG_6939 was induced on the Mycobacterium smegmatis background. Screening of synthetic chemical libraries was performed to identify compounds with higher anti-mycobacterial activity in the presence of parA antisense. Differentially active compounds were validated for specific inhibition of purified ParA protein from M. tuberculosis (Rv3918c). ParA inhibitors were then characterized for their activity towards M. tuberculosis in vitro. Results Under a number of culture conditions, parA antisense expression in M. smegmatis resulted in reduced growth. This effect on growth provided a basis for the detection of compounds that increased susceptibility to expression of parA antisense. Two compounds identified from library screening, phenoxybenzamine and octoclothepin, also inhibited the in vitro ATPase activity of ParA from M. tuberculosis. Structural in silico analyses predict that phenoxybenzamine and octoclothepin undergo interactions compatible with the active site of ParA. Octoclothepin exhibited significant bacteriostatic activity towards M. tuberculosis. Conclusions Our data support the use of whole-cell differential antisense screens for the discovery of inhibitors of specific anti-tubercular drug targets. Using this approach, we have identified an inhibitor of purified ParA and whole cells of M. tuberculosis. PMID:20810423

    Automated analysis of unstructured text documents (e.g., web pages, newswire articles, research publications, business reports) is a key capability for solving important problems in areas including decision making, risk assessment, social network analysis, intelligence analysis, scholarly research and others. However, as data sizes continue to grow in these areas, scalable processing, modeling, and semantic analysis of text collections becomes essential. In this paper, we present the ParaText text analysis engine, a distributed memory software framework for processing, modeling, and analyzing collections of unstructured text documents. Results on several document collections using hundreds of processors are presented to illustrate the exibility, extensibility, and scalability of the the entire process of text modeling from raw data ingestion to application analysis.

  11. Pneumatic protection applied to an airbag for para-gliders

    1998-02-01

    We present a theory of pneumatic protection based on the laws of thermodynamics, elasticity and fluid mechanics. A general pneumatic protection system is made up of several communicating compartments, the differences in pressure of the compartments generating a transfer of mass and energy between them. The transfer offers interesting possibilities to improve the performance of the system. An example of this type of protection in aerial sport is the airbag for para-gliders, it is used in this paper to illustrate the theory. As the pressure in the airbag depends uniquely on its volume, the geometric model in the theory can be simplified. Experiments carried out with crash-test dummies equipped with sensors have confirmed the theoretical predictions.

    Hernandez-Sosa, G.; Simbrunner, C.; Höfler, T.; Moser, A.; Werzer, O.; Kunert, B.; Trimmel, G.; Kern, W.; Resel, R.; Sitter, H.

    In this contribution the deposition of Para-sexiphenyl (PSP) layers on poly (diphenyl bicyclo[2.2.1]hept-5-ene-2,3-dicarboxylate) (PPNB) by Hot Wall Epitaxy (HWE) is reported. It is demonstrated that pre-treating the substrate by UV-illumination induces a clear change in the morphology of the grown PSP films due to the polarity modification of the substrate surface. PPNB surface polarity increases when illuminated by UV via photo-Fries rearrangement. By detailed atomic force microscopy analysis the influence on the growth kinetics by the substrate temperature, deposition time and particularly by the UVtreatment of the substrate was investigated. A high crystalline order of the films is underlined by the observation of growth spirals and terraced islands, providing mono-layer step heights of standing PSP-molecules.

    La calidad del seeing astronómico es ciertamente uno de los parámetros mas importantes que caracterizan el sitio de un observatorio. Por tanto se desea determinar si el alto valor de seeing observado con el telescopio de 2.15 m se debe a efectos internos y/o del entorno a la cupula o si se debe simplemente al seeing propio del lugar. El actual mecanismo de refrigeración del espejo primario del 2.15, parece haber mejorado notablemente la calidad del seeing. Sin embargo se hace necesario saber hasta que punto el valor del seeing puede ser mejorado. La primera etapa del proyecto consistió en la puesta a punto del telescopio emplazado para este propósito y la adquisición de las primeras medidas tentativas de seeing.

    "Temporary" henna tattoos (skin painting or pseudotattooing) are in vogue among American and European youngsters, particularly when vacationing. A 17-year-old girl presented with a severe contact dermatitis of her scalp and face after having dyed her hair with a permanent oxidative hair dye. She denied previous use of oxidative hair dye. Eight months earlier she had a "temporary" henna tattoo applied on her shoulder by a transient artist in downtown Montreal and developed an acute, erythematous, edematous eruption that resolved with residual, prolonged hyperpigmentation. As henna tattooing is a lengthy and tedious procedure, para-phenylenediamine (PPD) may be added to the mixture to accelerate the process, to darken, and to give more precision to the design. This short-lived fad can have longer-term sequelae then expected, ranging from postinflammatory hyperpigmentation of the tattoo site to permanent sensitization to PPD and related compounds.

    This paper presents a finite-volume method, together with fully adaptive multi-resolution scheme to obtain spatial adaptation, and a Runge-Kutta-Fehlberg scheme with a local time-varying step to obtain temporal adaptation, to solve numerically the known "bidominio" equations that model the electrical activity of the tissue in the myocardium. Two simple models are considered for membrane flows and ionic currents. First we define an approximate solution and we verify its convergence to the corresponding weak solution of the continuum problem, obtaining in this way an alternative demonstration that the continuum problem is well-posed. Next we introduce the multiresolution technique and derive an optimal noise reduction threshold. The efficiency and precision of our method is seen in the reduction of machine time, memory usage, and errors in comparison to other methods. ----- En este trabajo se presenta un metodo de volumenes finitos enriquecido con un esquema de multiresolucion completamente adaptativo para obte...

    Herein, we demonstrate magnetic resonance imaging (MRI) inthe gas phase using para-hydrogen (p-H2)-induced polarization. A reactantmixture of H2 enriched in the paraspin state and propylene gas is flowedthrough a reactor cell containing a heterogenized catalyst, Wilkinson'scatalyst immobilized on modified silica gel. The hydrogenation product,propane gas, is transferred to the NMR magnet and is spin-polarized as aresult of the ALTADENA (adiabatic longitudinal transport and dissociationengenders net alignment) effect. A polarization enhancement factor of 300relative to thermally polarized gas was observed in 1D1H NMR spectra.Enhancement was also evident in the magnetic resonance images. This isthe first demonstration of imaging a hyperpolarized gaseous productformed in a hydrogenation reaction catalyzed by a supported catalyst.This result may lead to several important applications, includingflow-through porous materials, gas-phase reaction kinetics and adsorptionstudies, and MRI in low fields, all using catalyst-free polarizedfluids.

    Entende-se por cosmoeducação o desenvolvimento vivencial da unidade homem-cosmo. Este conceito é norteado pela psicologia transpessoal, que estuda o ser humano em sua totalidade, onde suas relações ecológicas e cósmicas são de grande importância. Constata-se uma necessidade latente no ser humano moderno em resgatar uma relação holística com o Universo. Neste trabalho exploramos meios de cultivar a consciência de que o ser humano constitui parte integrante do cosmo e se relaciona com este com o objetivo de promover em si uma percepção ambiental mais ampla. Nossa hipótese de trabalho inicial foi que o ensino de conteúdos básicos em astronomia realizado através de uma abordagem holística, que incorpore práticas vivenciais correlacionadas àqueles conteúdos, pode despertar no indivíduo sua identidade cósmica. O método que utilizamos é o fenomenológico e o universo desta pesquisa é um grupo de estudantes da disciplina de Astronomia (Curso de Licenciatura em Geografia/UFRN), onde realizamos observação participante, entrevistas, depoimentos e as práticas vivenciais mencionadas. Neste caso estamos desenvolvendo e adaptando exercícios de algumas técnicas terapêuticas de psicologia transpessoal, que um de nós (LALM) tem aplicado no contexto clínico, para trabalhar aspectos cognitivos envolvidos naquele processo de conscientização cósmica. Resultados parciais claramente referendam a hipótese inicial. Um resultado a destacar é fruto de uma dinâmica de representação corporal interiorizada do eclipse lunar, envolvendo um pequeno grupo daqueles estudantes, na qual conteúdos míticos afloraram de maneira espontânea e contundente para todos, sugerindo ressonância, ou pelo menos isomorfismo, entre o macro e o microcosmo. Este e outros resultados são discutidos em detalhe neste trabalho. (PPGECNM/UFRN; PRONEX/FINEP; NUPA/USP; Temáticos/FAPESP).

  3. The Ratio of Ortho- to Para-H2 in Photodissociation Regions

    Amiel Sternberg; David A. Neufeld

    1998-12-02

    We discuss the ratio of ortho- to para-H2 in photodissociation regions (PDRs). We draw attention to an apparent confusion in the literature between the ortho-to-para ratio of molecules in FUV-pumped vibrationally excited states, and the H2 ortho-to-para abundance ratio. These ratios are not the same because the process of FUV-pumping of fluorescent H2 emission in PDRs occurs via optically thick absorption lines. Thus, gas with an equilibrium ratio of ortho- to para-H2 equal to 3 will yield FUV-pumped vibrationally excited ortho-to-para ratios smaller than 3, because the ortho-H2 pumping rates are preferentially reduced by optical depth effects. Indeed, if the ortho and para pumping lines are on the ``square root'' part of the curve-of-growth, then the expected ratio of ortho and para vibrational line strengths is the square root of 3, ~ 1.7, close to the typically observed value. Thus, contrary to what has sometimes been stated in the literature, most previous measurements of the ratio of ortho- to para-H2 in vibrationally excited states are entirely consistent with a total ortho-to-para ratio of 3, the equilibrium value for temperatures greater than 200 K. We present an analysis and several detailed models which illustrate the relationship between the total ratios of ortho- to para-H2 and the vibrationally excited ortho-to-para ratios in PDRs. Recent Infrared Space Observatory (ISO) measurements of pure rotational and vibrational H2 emissions from the PDR in the star-forming region S140 provide strong observational support for our conclusions.

    We demonstrate the creation and observation ofpara-hydrogen-induced polarization in heterogeneous hydrogenationreactions. Wilkinson's catalyst, RhCl(PPh3)3, supported on eithermodified silica gel or a polymer, is shown to hydrogenate styrene intoethylbenzene and to produce enhanced spin polarizations, observed throughNMR, when the reaction was performed with H2 gas enriched in the paraspinisomer. Furthermore, gaseous phase para-hydrogenation of propylene topropane with two catalysts, the Wilkinson's catalyst supported onmodified silica gel and Rh(cod)(sulfos) (cod = cycloocta-1,5-diene;sulfos) - O3S(C6H4)CH2C(CH2PPh2)3) supported on silica gel, demonstratesheterogeneous catalytic conversion resulting in large spin polarizations.These experiments serve as a direct verification of the mechanism ofheterogeneous hydrogenation reactions involving immobilized metalcomplexes and can be potentially developed into a practical tool forproducing catalyst-free fluids with highly polarized nuclear spins for abroad range of hyperpolarized NMR and MRI applications.

    Purpose This single-institution retrospective review examines the management of uninfected para-anastomotic aneurysms of the abdominal aorta (PAAA), developed after infrarenal grafting. Materials and Methods From October 1979 to November 2005, 31 PAAA were observed in our Department. Twenty-six uninfected PAAA of degenerative etiology, including 24 false and 2 true aneurysms, were candidates for intervention and retrospectively included in our database for management and outcome evaluation. Six (23%) patients were treated as emergencies. Surgery included tube graft interposition (n = 12), new reconstruction (n = 8), and graft removal with extra-anatomic bypass (n = 3). Endovascular management (n = 3) consisted of free-flow tube endografts. Results The mortality rate among the elective and emergency cases was 5% and 66.6%, respectively (p = 0.005). The morbidity rate in elective cases was 57.8%, whereas 75% in emergency cases (p = 0.99). The survival rate during the follow-up was significantly higher for elective cases than for emergency cases. Conclusion Uninfected PAAA is a late complication of aortic grafting, tends to evolve silently and is difficult to diagnose. The prevalence is underestimated and increases with time since surgery. The mortality rate is higher among patients treated as an emergency than among patients who undergo elective surgery, therefore, elective treatment and aggressive management in the case of pseudoaneurysm are the keys to obtain a good outcome. Endovascular treatment could reduce mortality. Patients who undergo infrarenal aortic grafting require life-long surveillance after surgery. PMID:19430556

    Background: Para-dichlorobenzene (PDCB) is an active ingredient of mothballs, deodorizers and fumigants. Due to the easy availability of this chemical, there is a considerable risk for accidental or intentional toxic exposure. Recently, multiple cases of PDCB toxicity due to mothball ingestion were reported. PDCB toxicity can affect multiple organ systems including liver, kidneys, skin, lung and the central nervous system (CNS). CNS toxicity often results in leukoencephalopathy and heterogeneous neurological manifestations. Objectives: The objective of this study was to illustrate the clinical presentation, imaging findings, diagnosis and management of PDCB toxicity. Methods: We carried out a literature review of the pharmacological and toxicological properties of PDCB. Conclusions: PDCB and other aromatic hydrocarbons are capable of CNS tissue damage and in promoting functional neurological decline. While very little is currently known about prevalence of PDCB addiction, it cannot be ruled out that its illicit use among young people is under-recognized. The number of cases of PDCB toxicity might also rise due to the increasing industrial and domestic use of this chemical. PMID:24790648

  7. Quadrupole Approximation for Para-Positronium in Relativistic Schrödinger Theory

    2011-09-11

    The non-relativistic energy levels of para-positronium are calculated in the quadrupole approximation of the interaction potential. This approximation technique takes into account the anisotropy of the electrostatic electron-positron interaction in the lowest order. The states due to different values of the quantum number $(l_z)$ of angular momentum are found to be no longer degenerate as is the case in the conventional theory. The physical origin of this elimination of the conventional degeneracy may intuitively be attributed to the state-dependent inertial \\emph{broadening} of the rotating charge clouds; the corresponding \\emph{anisotropic} deformation (in the quadrupole approximation) lowers then the negative electrostatic interaction energy. The result of this influence of anisotropy is that the states with $l_z=0$ adopt smaller binding energy whereas the states with maximal value of $|l_z|$ (for fixed principal quantum number $n$) have the largest binding energy within the angular momentum multiplet $(-|l_{z,\\mathrm{max}}| \\le l_z \\le |l_{z,\\mathrm{max}}|)$. This yields a certain kind of electric fine-structure splitting with the splitted RST levels being placed in a relatively narrow band around the (highly degenerated) conventional levels.

    We have demonstrated that the molecular hydrogen obtained from atomic recombination at 300 mK has nonstatistic ortho--para ratio. The ortho para conversion is less than 3% in the vibrational relaxation phase. We suggest that it is possible to carry out detailed comparison between calculations and measurements at conditions similar to our experiments.

    A method is disclosed for isolating and identifying modified para-nitrobenzyl esterases which exhibit improved stability and/or esterase hydrolysis activity toward selected substrates and under selected reaction conditions relative to the unmodified para-nitrobenzyl esterase. The method involves preparing a library of modified para-nitrobenzyl esterase nucleic acid segments (genes) which have nucleotide sequences that differ from the nucleic acid segment which encodes for unmodified para-nitrobenzyl esterase. The library of modified para-nitrobenzyl nucleic acid segments is expressed to provide a plurality of modified enzymes. The clones expressing modified enzymes are then screened to identify which enzymes have improved esterase activity by measuring the ability of the enzymes to hydrolyze the selected substrate under the selected reaction conditions. Specific modified para-nitrobenzyl esterases are disclosed which have improved stability and/or ester hydrolysis activity in aqueous or aqueous-organic media relative to the stability and/or ester hydrolysis activity of unmodified naturally occurring para-nitrobenzyl esterase. 43 figs.

  12. A mathematical model of ParA filament-mediated chromosome movement in Caulobacter crescentus.

    PubMed

    Shtylla, Blerta; Keener, James P

    2012-08-21

    Caulobacter crescentus uses the dynamic interactions between ParA and ParB proteins to segregate copies of its circular chromosome. In this paper, we develop two mathematical models of the movement of the circular chromosome of this bacterium during division. In the first model, posed as a set of stochastic differential equations (SDE), we propose that a simple biased diffusion mechanism for ParB/ParA interactions can reproduce the observed patterns of ParB and ParA localization in the cell. The second model, posed as a set of nonlinear partial differential equations, is a continuous treatment of the problem where we use results from the SDE model to describe ParB/ParA interactions and we also track ParA monomer dynamics in the cytoplasm. For both models, we show that if ParB complexes bind weakly and nonspecifically to ParA filaments, then they can closely track and move with the edge of a shrinking ParA filament bundle. Unidirectional chromosome movement occurs when ParB complexes have a passive role in depolymerizing ParA filaments. Finally, we show that tight control of ParA filament dynamics is essential for proper segregation. PMID:22588023

    2011-05-28

    Quantum fluctuations significantly increase the self-diffusive motion of para-hydrogen adsorbed in narrow carbon nanotubes at 30 K comparing to its classical counterpart. Rigorous Feynman's path integral calculations reveal that self-diffusive motion of para-hydrogen in a narrow (6,6) carbon nanotube at 30 K and pore densities below ?29 mmol cm(-3) is one order of magnitude faster than the classical counterpart. We find that the zero-point energy and tunneling significantly smoothed out the free energy landscape of para-hydrogen molecules adsorbed in a narrow (6,6) carbon nanotube. This promotes a delocalization of the confined para-hydrogen at 30 K (i.e., population of unclassical paths due to quantum effects). Contrary the self-diffusive motion of classical para-hydrogen molecules in a narrow (6,6) carbon nanotube at 30 K is very slow. This is because classical para-hydrogen molecules undergo highly correlated movement when their collision diameter approached the carbon nanotube size (i.e., anomalous diffusion in quasi-one dimensional pores). On the basis of current results we predict that narrow single-walled carbon nanotubes are promising nanoporous molecular sieves being able to separate para-hydrogen molecules from mixtures of classical particles at cryogenic temperatures.

  14. Um enfoque antropológico para o ensino de astronomia no nível médio

    NASA Astrophysics Data System (ADS)

    Costa, G. B.; Jafelice, L. C.

    2003-08-01

    Há uma enorme carência de materiais didático-pedagógicos em astronomia para professores do ensino médio, sobretudo materiais que explorem também aspectos humanísticos. A origem do Universo é um bom exemplo desta constatação central. Embora tal origem teve explicações culturais diversas, os professores não têm informações sobre isso e muito menos material que trabalhe diferentes visões de mundo e treinamento que os capacite a abordá-las devidamente. Conseqüentemente o ensino de astronomia costuma ser tecnicista e dissociado do aspecto humano que alimenta o grande interesse e curiosidade que esses temas despertam. Aqui apresentamos propostas visando contribuir para reverter esse quadro e trabalhamos distintas visões de Universo: espontâneas, autóctones e científicas. Desenvolvemos práticas, materiais instrucionais e textos para viabilizar a adoção de um enfoque antropológico para o ensino de astronomia no nível médio, no qual as culturas humanística e científica sejam integradas de uma maneira contextualizada e eficaz para aquele ensino. Estas propostas foram aplicadas em um curso de treinamento para professores da rede pública de diferentes disciplinas. A receptividade dos professores à abordagem proposta e os resultados alcançados foram muito estimulantes. Destes, destacamos: produção de roteiros de atividades; desenvolvimento de práticas didático-pedagógicas específicas (e.g., encenação de mitos; dança primordial guarani; "criação" de constelações e interpretações pluriculturais; etc.); e sugestões concretas para a efetiva realização de um ensino interdisciplinar contextualizado, onde questões cosmogônicas servem de mote para iniciar tal ensino. Discutimos estes resultados e como o enfoque adotado pode instrumentalizar os professores para leituras de mundo que incluem naturalmente aspectos culturais, sociais e históricos associados aos temas estudados.

    The ParaHox gene cluster contains three homeobox genes, Gsx, Xlox and Cdx and has been demonstrated to be an evolutionary sister of the Hox gene cluster. Among deuterostomes the three genes are found in the majority of taxa, whereas among protostomes they have so far been isolated only in the phylum Sipuncula. We report the partial sequences of all three ParaHox genes in the polyplacophoran Nuttallochiton mirandus, the first species of the phylum Mollusca where all ParaHox genes have been isolated. This finding has phylogenetic implications for the phylum Mollusca and for its relationships with the other lophotrochozoan taxa. PMID:16331637

Tal es el caso de los modelos desarrollados en la década del '60 por Sweet, Parker, Petschek y Sonnerup. En esta comunicación presentamos una solución de las ecuaciones MHD en el entorno del origen, construyendo series bidimensionales para todas las magnitudes físicas involucradas. Valiéndonos de la alta simetría y de las características del problema, logramos reducir el número de coeficientes a calcular. Utilizamos un programa autoconsistente para extender el cálculo a regiones vecinas con difusión moderada o despreciable.

  17. Pentacene transistor encapsulated by poly-para-xylylene behaving as gate dielectric insulator and passivation film

    2005-10-01

    We present pentacene thin-film transistors with poly-para-xylylene gate dielectric and passivation films for plastic electronics. Both the poly-para-xylylene films are formed by dry chemical vapor deposition at room temperature. An organic pentacene channel is fully encapsulated by poly-para-xylylene films, except in the area of electrode connection. Passivation induces little degradation of the organic transistor properties. In addition, a small amount of charge transfer molecules are introduced between the pentacene channel and the metal electrodes to improve device performance. Contact resistance is sufficiently reduced by the employment of the charge transfer molecules, which is analyzed using a transmission-line model.

    2014-01-01

    Human and mouse genomes contain six ParaHox genes implicated in gut and neural patterning. In coelacanths and cartilaginous fish, an additional ParaHox gene exists—Pdx2—that dates back to the genome duplications in early vertebrate evolution. Here we examine the genomic arrangement and flanking genes of all ParaHox genes in coelacanths, to determine the full complement of these genes. We find that coelacanths have seven ParaHox genes in total, in four chromosomal locations, revealing that five gene losses occurred soon after vertebrate genome duplication. Comparison of intergenic sequences reveals that some Pdx1 regulatory regions associated with development of pancreatic islets are older than tetrapods, that Pdx1 and Pdx2 share few if any conserved non-coding elements, and that there is very high sequence conservation between coelacanth species.

    In an effort to develop a source of H3+ that is almost entirely in a single quantum state (J =K=1), we have successfully generated a plasma that is enriched to ˜83% in para-H3+ at a rotational temperature of 80 K. This enrichment is a result of the nuclear spin selection rules at work in hydrogenic plasmas, which dictate that only para-H3+ will form from para-H2, and that para-H3+ can be converted to ortho-H3+ by subsequent reaction with H2. This is the first experimental study in which the H2 and H3+ nuclear spin selection rules have been observed at cold temperatures. The ions were produced from a pulsed solenoid valve source, cooled by supersonic expansion, and interrogated via continuous-wave cavity ringdown spectroscopy.

  14. pH-dependent nitration of para-hydroxyphenylacetic acid in the stomach.

    The major urinary metabolite of nitrotyrosine is 3-nitro-4-hydroxyphenylacetic acid (3-Nitro-HPA). However, recent animal studies have shown that the majority of urinary 3-Nitro-HPA is derived from nitration of endogenous para-hydroxyphenylacetic acid (HPA), a metabolite of tyrosine. One potential site for the formation of 3-Nitro-HPA is the stomach, where nitrous acid is formed by the reaction of nitrite in saliva with gastric acid. The aim of this study was to determine whether there is pH-dependent nitration of salivary para-hydroxyphenylacetic acid or tyrosine, and the effects of dietary nitrate. Healthy volunteers (n = 18) ingested either a low or high nitrate diet, with and without the administration of omeprazole, a proton pump inhibitor. Urinary 3-Nitro-HPA excretion increased from 197 +/- 52 to 319 +/- 88 microg/day on switching from a low to a high nitrate diet (P < 0.05), and decreased (166 +/- 53 mug/day, P < 0.05) when gastric pH was increased by omeprazole. To determine whether 3-Nitro-HPA can be formed by nitration of para-hydroxyphenylacetic acid in the stomach, 500 microg of deuterated para-hydroxyphenylacetic acid was ingested with a high nitrate meal. This led to the excretion of both deuterated HPA and 3-Nitro-HPA in the urine, confirming that para-hydroxyphenylacetic acid is absorbed, and nitrated. Since omeprazole decreases the formation of 3-Nitro-HPA, presumably by decreasing the nitration of endogenous para-hydroxyphenylacetic acid present in saliva, and the observation that ingested deuterated para-hydroxyphenylacetic acid is nitrated and excreted, we conclude that endogenous para-hydroxyphenylacetic acid is nitrated in the stomach, absorbed, and excreted as 3-Nitro-HPA.

  7. para-C-H Borylation of Benzene Derivatives by a Bulky Iridium Catalyst.

    2015-04-22

    A highly para-selective aromatic C-H borylation has been accomplished. By a new iridium catalyst bearing a bulky diphosphine ligand, Xyl-MeO-BIPHEP, the C-H borylation of monosubstituted benzenes can be affected with para-selectivity up to 91%. This catalytic system is quite different from the usual iridium catalysts that cannot distinguish meta- and para-C-H bonds of monosubstituted benzene derivatives, resulting in the preferred formation of meta-products. The para-selectivity increases with increasing bulkiness of the substituent on the arene, indicating that the regioselectivity of the present reaction is primarily controlled by steric repulsion between substrate and catalyst. Caramiphen, an anticholinergic drug used in the treatment of Parkinson's disease, was converted into five derivatives via our para-selective borylation. The present [Ir(cod)OH]2/Xyl-MeO-BIPHEP catalyst represents a unique, sterically controlled, para-selective, aromatic C-H borylation system that should find use in streamlined, predictable chemical synthesis and in the rapid discovery and optimization of pharmaceuticals and materials.

  8. Competing ParA Structures Space Bacterial Plasmids Equally over the Nucleoid

    PubMed Central

    Gerdes, Kenn; Howard, Martin

    2014-01-01

    Low copy number plasmids in bacteria require segregation for stable inheritance through cell division. This is often achieved by a parABC locus, comprising an ATPase ParA, DNA-binding protein ParB and a parC region, encoding ParB-binding sites. These minimal components space plasmids equally over the nucleoid, yet the underlying mechanism is not understood. Here we investigate a model where ParA-ATP can dynamically associate to the nucleoid and is hydrolyzed by plasmid-associated ParB, thereby creating nucleoid-bound, self-organizing ParA concentration gradients. We show mathematically that differences between competing ParA concentrations on either side of a plasmid can specify regular plasmid positioning. Such positioning can be achieved regardless of the exact mechanism of plasmid movement, including plasmid diffusion with ParA-mediated immobilization or directed plasmid motion induced by ParB/parC-stimulated ParA structure disassembly. However, we find experimentally that parABC from Escherichia coli plasmid pB171 increases plasmid mobility, inconsistent with diffusion/immobilization. Instead our observations favor directed plasmid motion. Our model predicts less oscillatory ParA dynamics than previously believed, a prediction we verify experimentally. We also show that ParA localization and plasmid positioning depend on the underlying nucleoid morphology, indicating that the chromosomal architecture constrains ParA structure formation. Our directed motion model unifies previously contradictory models for plasmid segregation and provides a robust mechanistic basis for self-organized plasmid spacing that may be widely applicable.

  9. Spontaneous Emission Between - and Para-Levels of Water-Ion H_2O^+

    2012-06-01

    Nuclear spin conversion interaction of water ion, H_2O^+, has been studied to derive spontaneous emission lifetime between ortho- and para-levels. H_2O^+ is a radical ion with the ^2B_1 electronic ground state. Its off-diagonal electron spin-nuclear spin interaction term, Tab(S_a? I_b + S_b? I_a), connects para and ortho levels, because ? I = I_1 - I_2 has nonvanishing matrix elements between I = 0 and 1. The mixing by this term with Tab = 72 MHz predicted by ab initio theory in the MRD-CI/Bk level, is many orders of magnitude larger than for closed shell molecules because of the large magnetic interaction due to the un-paired electron. Using the molecular constants reported by Mürtz et al. by FIR-LMR, we searched for ortho and para coupling channels below 1000 cm-1 with accidental near degeneracy between para and ortho levels. For example, hyperfine components of the 42,2(ortho) and 33,0(para) levels mix by 1.2 × 10-3 due to their near degeneracy (? E = 0.417 cm-1), and give the ortho-para spontaneous emission lifetime of about 0.63 year. The most significant low lying 10,1(para) and 11,1(ortho) levels, on the contrary, mix only by 8.7 × 10-5 because of their large separation (? E = 16.267 cm-1) and give the spontaneous emission lifetime from 10,1(para) to 00,0(ortho) of about 100 year.These results qualitatively help to understand the observed high ortho- to para- H_2O^+ ratio of 4.8 ± 0.5 toward Sgr B2 but they are too slow to compete with the conversion by collision unless the number density of the region is very low (n ˜1 cm-3) or radiative temperature is very high (T_r > 100 K).

    Fourier transform infrared spectroscopy (FTIR) experiments together with interaction potential calculations are performed to interpret the adsorption-desorption properties of para and ortho H2 molecules physisorbed on the (001) faces of NaCl crystallites. Isotherms of the adsorption process show preferential adsorption of para-H2 from gaseous normal-H2 at surface temperature around 10 K. Isobars of the desorption process show preferential desorption of para-H2 from a mixed ortho-H2 and para-H2 adsorbate. A quantum description of the molecular motions corroborates preferential adsorption of p- and (M=±1) o-H2 on the cation sites, as proposed in previous classical studies. It is shown that the adsorption energy is smaller for the para than for the (M=±1) ortho species in agreement with experimental measurement of desorption energy, while (M=0) o-H2 is only slightly bound to the substrate. This indicates that the ionic surface can discriminate all the H2 species. The determination of the bar spectrum for a set of independently adsorbed H2 species can interpret most of the infrared signals assigned to adsorption on the terrace sites. More specially the experimental behavior, with temperature and coverage, of the frequencies and relative intensities of the pure vibrational peaks and of the translation-vibration combination bands is very well explained in terms of hindered external motions of the admolecule.

    2012-12-01

    This study aims to estimate the carbon stock and sequestration in Para rubber plantation of East Thailand using the THAICHOTE (Thailand Earth Observation System data). For that purpose we identify the area of every stage class Para rubber plantation by the analysis of different image objects (i.e., rule base and multiple regression classifications) and we map the carbon stock and sequestration of each Para rubber class using biomass allometric regressions and carbon content equations. THAICHOTE data include Multispectral image (4 bands at 15x15 m spatial resolution), Panchromatic image (2x2 m spatial resolution) and Stereo image, data acquisition from December 2011-April 2012. The preliminary investigated area is located in Wangchun, (Eastern, Thailand) and covers about 20 Km2. Calibrating the class stage, by image analysis that integrated edge-based segmentation, reflectance, remote sensing indices, texture analysis and canopy height model (CHM), we found that best classification was obtained by multiple regression (accuracy of 80%) compared to rule base logical operation (accuracy 70%) suggesting that manual 3D stereo measurements or Light Detection And Ranging (LiDAR) both are able to construct the CHM. The results of this study indicate that for a total Para rubber biomass of 14,651 tons, the amount of stored carbon is of 7,326 tons. Mature stage of Para rubber plantations exhibits the highest capacity of sequestering with a global flux of 0.21 tons C/ Km2/year.

    Allergic contact dermatitis reaction to topical "black henna" tattoo is usually described secondary to the organic dye para-phenylenediamine, a derivative of analine. Allergic contact dermatitis reactions to para-phenylenediamine are well recognized and most commonly involve an eczematous reaction that may become generalized and an acute angio-edema. Only four previous instances have been reported of an erythema multiforme-like reaction to para-phenylenediamine and its derivatives, including only one mild reaction to a tattoo. A vesicular erythema multiforme-like reaction has not been reported. An erythema multiforme-like reaction to contact allergens is usually caused by potent allergens including plant quinolones in Compositae and sesquiterpene lactones in exotic woods, and it is also reported to topical drugs, epoxy resin, metals (particularly nickel), and various chemicals. A generalized vesicular erythema multiforme-like reaction is unusual, and rarely reported. We describe a 6-year-old boy who developed a localized, eczematous and severe generalized vesicular erythema multiforme-like contact allergy to para-phenylenediamine secondary to a henna tattoo. As henna tattoos are becoming increasingly popular, one should be aware of the possibility of such a reaction. This presentation also highlights the call to ban the use of para-phenylenediamine and its derivatives in dyes. PMID:18429780

The data were collected and compiled from published research papers, patents and from various databases. The current release of ParaPep holds 863 entries among which 519 are unique peptides. In addition to peptides having natural amino acids, ParaPep also consists of peptides having d-amino acids and chemically modified residues. In ParaPep, most of the peptides have been evaluated for growth inhibition of various species of Plasmodium, Leishmania and Trypanosoma. We have provided comprehensive information about these peptides that include peptide sequence, chemical modifications, stereochemistry, antiparasitic activity, origin, nature of peptide, assay types, type of parasite, mode of action and hemolytic activity. Structures of peptides consisting of natural, as well as modified amino acids have been determined using state-of-the-art software, PEPstr. To facilitate users, various user-friendly web tools, for data fetching, analysis and browsing, have been integrated. We hope that ParaPep will be advantageous in designing therapeutic peptides against parasitic diseases. Database URL: http://crdd.osdd.net/raghava/parapep/ PMID:24923818

    The excitation temperature T 01 derived from the relative intensities of the J = 0 (para) and J = 1 (ortho) rotational levels of H2 has been assumed to be an accurate measure of the kinetic temperature in interstellar environments. In diffuse molecular clouds, the average value of T 01 is ~70 K. However, the excitation temperature T(H+ 3) derived from the (J, K) = (1, 1) (para) and (1, 0) (ortho) rotational levels of H+ 3 has been observed to be ~30 K in the same types of environments. In this work, we present observations of H+ 3 in three additional diffuse cloud sight lines for which H2 measurements are available, showing that in four of five cases T 01 and T(H+ 3) are discrepant. We then examine the thermalization mechanisms for the ortho:para ratios of H+ 3 and H2, concluding that indeed T 01 is an accurate measure of the cloud kinetic temperature, while the ortho:para ratio of H+ 3 need not be thermal. By constructing a steady-state chemical model taking into account the nuclear spin dependence of reactions involving H+ 3, we show that the ortho:para ratio of H+ 3 in diffuse molecular clouds is likely governed by a competition between dissociative recombination with electrons and thermalization via reactive collisions with H2. Based in part on observations made with ESO Telescopes at the La Silla or Paranal Observatories under program ID 384.C-0618.

    It is highly popular among children and young adults to have temporary henna tattoos on their bodies in different colors and figures. Henna is a greenish natural powder obtained from the flowers and dry leaves of Lawsonia alba plant and its allergenicity is very low. Henna is also used in combination with other coloring substances such as para-phenylenediamine in order to darken the color and create a permanent tattoo effect. Para-phenylenediamine is a substance with high allergenicity potential and may cause serious allergic reactions. Here, we aimed to draw attention to the potential harms of para-phenylenediamine containing temporary tattoos by presenting a child patient who developed allergic contact dermatitis after having a scorpion-shaped temporary tattoo on his forearm.

Contamination or adulteration of the dyes with para-phenylendiamine has been identified as major cause of active sensitization and elicitation of severe allergic contact dermatitis. Sequelae include permanent sensitization, hyper- or hypopigmentation, scarring, keloids, and hypertrichosis. We report a rare case of irritant dermatitis to an unknown ingredient in a black henna tattoo with consecutive hypopigmentation. Sensitization to para-phenylendiamine and other para-compounds was excluded by patch test evaluation. This is relevant for future exposure to consumer products such as hair dyes or in occupational settings. Generally, black henna tattoos, particularly if done with dyes of unknown composition, should be strongly discouraged. PMID:23690526

  17. Um supressor de fundo térmico para a câmara infravermelha CamIV

    O ângulo sólido subtendido pelos pixels na câmara infravermelha do NexGal (CamIV) que operamos no OPD/LNA contém contribuições provenientes do sistema de coleta de fluxo propriamente dito - sendo esta a parte que interessa para as medidas astronômicas - e contribuições da obstrução central, sistema de suporte do espelho secundário e região exterior à pupila de entrada do telescópio. Estas últimas contribuições são devi-das à emissão de corpo negro à temperatura ambiente e aumentam exponencialmente para comprimentos de onda maiores que 2 micra (banda K, no infravermelho próximo). Embora a resultante pode ser quantificada e subtraída dos sinais relevantes, sua variância se adiciona à variância do sinal, e pode ser facilmente a contribuição domi-nante para a incerteza final das medidas, tornando ineficiente o processo de extração de informação e degradando a sensibilidade da câmara. A maneira clássica de resolver esse problema em sistemas ópticos que operam no infravermelho, onde os efeitos da emissão térmica do ambiente são importantes, é restringir o ângulo sólido subtendido pelos pixels individuais exclusivamente aos raios provenientes do sistema óptico. Para tanto, projeta-se uma imagem real, bastante reduzida, da pupila de entrada do sistema óptico num anteparo que transmita para o sistema de imageamento só o que interessa, bloqueando as contribuições das bordas externas à pupila de entrada, obstrução central do telescópio e sistema de suporte. Como a projeção é realizada em ambiente criogênico, a contribuição térmica espúria é efetivamente eliminada. Nós optamos por um sistema do tipo Offner para implementar na prática esta função. Trata-se de um sistema baseado em espelhos esféricos, bastante compacto e ajustado por construção. A opção por espelhos do mesmo material que o sistema de suporte (Alumínio) minimiza a dilatação diferencial, crítica nesse tipo de aplicação. Apresentamos as soluções detalhadas do projeto óptico-mecânico, bem como uma análise de flexões e desempenho em termos de qualidade de imagem.

    Sponges are simple animals with few cell types, but their genomes paradoxically contain a wide variety of developmental transcription factors, including homeobox genes belonging to the Antennapedia (ANTP) class, which in bilaterians encompass Hox, ParaHox and NK genes. In the genome of the demosponge Amphimedon queenslandica, no Hox or ParaHox genes are present, but NK genes are linked in a tight cluster similar to the NK clusters of bilaterians. It has been proposed that Hox and ParaHox genes originated from NK cluster genes after divergence of sponges from the lineage leading to cnidarians and bilaterians. On the other hand, synteny analysis lends support to the notion that the absence of Hox and ParaHox genes in Amphimedon is a result of secondary loss (the ghost locus hypothesis). Here we analysed complete suites of ANTP-class homeoboxes in two calcareous sponges, Sycon ciliatum and Leucosolenia complicata. Our phylogenetic analyses demonstrate that these calcisponges possess orthologues of bilaterian NK genes (Hex, Hmx and Msx), a varying number of additional NK genes and one ParaHox gene, Cdx. Despite the generation of scaffolds spanning multiple genes, we find no evidence of clustering of Sycon NK genes. All Sycon ANTP-class genes are developmentally expressed, with patterns suggesting their involvement in cell type specification in embryos and adults, metamorphosis and body plan patterning. These results demonstrate that ParaHox genes predate the origin of sponges, thus confirming the ghost locus hypothesis, and highlight the need to analyse the genomes of multiple sponge lineages to obtain a complete picture of the ancestral composition of the first animal genome.

    Inelastic neutron scattering, far-infrared spectroscopy, and cryogenic nuclear magnetic resonance are used to investigate the quantized rotation and ortho–para conversion of single water molecules trapped inside closed fullerene cages. The existence of metastable ortho-water molecules is demonstrated, and the interconversion of ortho-and para-water spin isomers is tracked in real time. Our investigation reveals that the ground state of encapsulated ortho water has a lifted degeneracy, associated with symmetry-breaking of the water environment. PMID:22837402

    According to article 191 of the 1974 Yugoslavian Constitution, men have the right to decide freely on the birth of a child. According to the Law of conditions and proceedings for permitting abortion (1978), pregnant women are allowed to make the decision to abort freely up to the 10th week of pregnancy. Between the 10th and 20th week there are medical, eugenic, and moral indications for abortion; medical indication being disease or a high risk to the other of the mother; eugenic indications being heredity deformities in the fetus or heavy abnormalities; and moral indications being pregnancies caused by the commission of a crime like rape or incest. In the region of Vojvodina, population 2 million, there were 25,000 live births and twice as many abortions. The traditions of Yugoslavia are that fetuses have a right to life including a high quality of life free from disease and genetic abnormalities. Doctors are relied upon to take the greatest responsibility in terms of doing the ethical things for a pregnant woman and the fetus. Modern medical technology allows doctors and patients to have ever greater amounts of information so that an informed decision can be made about the health and well being of the mother and the fetus.

    Background Common variable Immunodeficiency (CVIDs) is characterized by a deficiency in antibody production and also generates enormous morbidity of school absenteeism and dropout or cause layoffs. All chronic diseases affect quality of life of patients, in this particular case CVIDs. The use of instruments like the SF - 36 provides information about the patients' perception of their disease and its environment. The objective is to determine the quality of life of adult patients with CVID who receive replacement therapy through the use of SF-36. Methods We conducted a cross-sectional cohort study, which included all patients diagnosed with CVID in our hospital with approval from local research committee F-2011-3601-21. We analyzed the results with descriptive statistics and the SF-36 was used the method of Rand Group. Results Involving 11 patients with CVID, 4 men and 7 women, average age 30 years (18–53) years. The results show a reduction in quality of life of 65%, without gender difference. However in general we see that men are more affected the physical role 31% and women in the general health 40%, In menthal health assesment, we found that in both genders is more affected in Vitality 55%, and Role Emotional least 84.72%. In relation to physical health, both genders showed greater involvement in aspects of general health 45% and less area affected is physical function 68 %. Conclusions CVID patients show a significant deterioration in their quality of life. It's important to highlight that there are not statistically different variations in quality of life. But the general perception of gender does vary without establishing differences between mental and physical health.

    Introduction Most data on de-escalation of empirical antimicrobial therapy has focused on ventilator-associated pneumonia. In this retrospective monocentric study, we evaluated de-escalation as part of a global strategy of empiric antibiotherapy management irrespective of the location and the severity of the infection. The goal of this trial was to assess the application of a de-escalation strategy and the impact in terms of re-escalation, recurrent infection and to identify variables associated with de-escalation. Methods All consecutive patients treated with empiric antibiotic therapy and hospitalized in the intensive care unit for at least 72 hours within a period of 16 months were included. We compared the characteristics and outcome of patients who have experienced de-escalation therapy with those who have not. Results A total of 116 patients were studied corresponding to 133 infections. Antibiotic therapy was de-escalated in 60 cases (45%). De-escalation, primarily accomplished by a reduction in the number of antibiotics used, was observed in 52% of severe sepsis or septic shock patients. Adequate empiric antibiotic and use of aminoglycoside were independently linked with de-escalation. De-escalation therapy was associated with a significant reduction of recurrent infection (19% vs 5% P = 0.01). Mortality was not changed by de-escalation. Conclusions As part of a global management of empiric antibiotherapy in an intensive care unit, de-escalation might be safe and feasible in a large proportion of patients. PMID:21167047

    The scandal of the Mediator(®) case led the legislature to take measures in order to regulate off-label drugs prescriptions. Indeed the law issued in December 29th, 2011 on strengthening the safety of drugs and all derivative health products came to pave the way for an "over-cautious" practice of medicine in line with the precautionary principle erected as a constitutional principle. The supervision of off-label prescribing has had a direct impact on the exercise of the medical profession and has resurrected the issues related to the freedom of prescription, the obligation to provide information to patients and in general their whole responsibility. It is important to mention that the prescribing act is part of the freedom and the strict prerogative of those skilled in the art: the physician in this case. The off-label prescription is commonly accepted in certain specialties, such as anesthesia and intensive care, oncology or pediatrics where it is even subject of a memorandum of use because of concerns regarding the availability of forms adapted to children. However, the physician must ensure that no appropriate therapeutic alternative is available and inform the patient, fundamental principle of the right to respect for the will of the person. Off-label use of the prostaglandin-E1 analogue misoprostol in obstetrics and gynecology is a good example. In fact, this drug obtained a marketing authorization for the treatment or prevention of peptic ulcers and other stomach disorders, is commonly used off-label when inducing labour or intrauterine device insertion. These are the issues that need to be clarify and carefully assessed in order to help physicians to understand the impact of the law and the state of the jurisprudence on the exercise of their profession.

    Conventional formalin-ether concentration method is a gold standard for the diagnosis of parasite infection. However, it may be time-consuming and laborious. We aimed to reveal the clinical usefulness of a modified formalin-ether concentration method using the Para Tube (KS Corporation, Korea) compared with the conventional method. A total of 117 fresh, unpreserved fecal samples composed to 90 negative controls and 27 positive controls with ova of Diphyllobothrium latum/D. nihonkaiense, ova of Clonorchis sinensis and cysts of Giardia lamblia were used in this study. Both methods showed comparable correct identification rate (87.2% for the Para Tube vs. 86.3% for the conventional method).When five samples were examined at once, the Para Tube method reduced the procedure time compared with the conventional method (19 min 58 sec vs. 23 min 18 sec, P=0.0286). We concluded that the modified formalin-ether concentration method using the Para Tube is a rapid, simple, and reliable fecal concentration method for clinical use. PMID:26131417

  11. Longitudinal nuclear spin relaxation of ortho- and para-hydrogen dissolved in organic solvents.

    PubMed

    Aroulanda, Christie; Starovoytova, Larisa; Canet, Daniel

    2007-10-25

    The longitudinal relaxation time of ortho-hydrogen (the spin isomer directly observable by NMR) has been measured in various organic solvents as a function of temperature. Experimental data are perfectly interpreted by postulating two mechanisms, namely intramolecular dipolar interaction and spin-rotation, with activation energies specific to these two mechanisms and to the solvent in which hydrogen is dissolved. This permits a clear separation of the two contributions at any temperature. Contrary to the self-diffusion coefficients at a given temperature, the rotational correlation times extracted from the dipolar relaxation contribution do not exhibit any definite trend with respect to solvent viscosity. Likewise, the spin-rotation correlation time obeys Hubbard's relation only in the case of hydrogen dissolved in acetone-d6, yielding in that case a spin-rotation constant in agreement with literature data. Concerning para-hydrogen, which is NMR-silent, the only feasible approach is to dissolve para-enriched hydrogen in these solvents and to follow the back-conversion of the para-isomer into the ortho-isomer. Experimentally, this conversion has been observed to be exponential, with a time constant assumed to be the relaxation time of the singlet state (the spin state of the para-isomer). A theory, based on intermolecular dipolar interactions, has been worked out for explaining the very large values of these relaxation times which appear to be solvent-dependent. PMID:17914761

    In patients with ovarian carcinoma, the presence of metastatic disease in a retroperitoneal lymph node is indicative of a poor prognosis. Although a "staging laparotomy" is required for proper treatment, definitive information concerning para-aortic and pelvic lymph node metastasis often is not available. To determine the incidence of retroperitoneal lymph node metastases in untreated cases of ovarian carcinoma, a prospective study by selective nodal biopsy was undertaken in 61 unselected patients with the following distribution: Stage I, 11; Stage II, 10; Stage III, 31; and Stage IV, 9. The incidence of para-aortic node metastasis overall was 37.7% and of pelvic node metastasis, 14.8%. Of 23 patients with positive para-aortic nodes, 30.4% had no concomitant pelvic node involvement. Direct relationships between nodal metastasis and clinical stage, tumor grade, and histologic type of tumor were demonstrated. The incidence of positive para-aortic nodes in Stage I disease was 18.2%; in Stage II, 20.0%; in Stage III, 41.9%; and in Stage IV, 66.7%. The corresponding incidence of pelvic node metastasis was 9.1% in Stage I, 10.0% in Stage II, 12.9% in Stage III, and 33.3% in Stage IV. Grade 3 tumors were associated most frequently with nodal involvement, with an incidence of positive para-aortic nodes of 52.5% and of positive pelvic nodes of 15.5%. In patients with a serous type of malignancy, the frequencies of positive para-aortic/pelvic nodes were 44.4%/16.7%, respectively; in the undifferentiated type, 50.0%/10.0%; in the clear cell type, 25.0%/25.0%; and in the mucinous type, 14.3%/14.3%. In this small series, 32 patients (52.5%) had positive retroperitoneal nodal involvement. It is concluded that selective biopsies of the para-aortic and pelvic lymph nodes should be part of any "staging laparotomy" for ovarian carcinoma, and that the true incidence of nodal involvement in these patients awaits further investigation.

  4. Ancient origins of axial patterning genes: Hox genes and ParaHox genes in the Cnidaria.

    PubMed

    Finnerty, J R; Martindale, M Q

    1999-01-01

    Among the bilaterally symmetrical, triploblastic animals (the Bilateria), a conserved set of developmental regulatory genes are known to function in patterning the anterior-posterior (AP) axis. This set includes the well-studied Hox cluster genes, and the recently described genes of the ParaHox cluster, which is believed to be the evolutionary sister of the Hox cluster (Brooke et al. 1998). The conserved role of these axial patterning genes in animals as diverse as frogs and flies is believed to reflect an underlying homology (i.e., all bilaterians derive from a common ancestor which possessed an AP axis and the developmental mechanisms responsible for patterning the axis). However, the origin and early evolution of Hox genes and ParaHox genes remain obscure. Repeated attempts have been made to reconstruct the early evolution of Hox genes by analyzing data from the triphoblastic animals, the Bilateria (Schubert et al. 1993; Zhang and Nei 1996). A more precise dating of Hox origins has been elusive due to a lack of sufficient information from outgroup taxa such as the phylum Cnidaria (corals, hydras, jellyfishes, and sea anemones). In combination with outgroup taxa, another potential source of information about Hox origins is outgroup genes (e.g., the genes of the ParaHox cluster). In this article, we present cDNA sequences of two Hox-like genes (anthox2 and anthox6) from the sea anemone, Nematostella vectensis. Phylogenetic analysis indicates that anthox2 (= Cnox2) is homologous to the GSX class of ParaHox genes, and anthox6 is homologous to the anterior class of Hox genes. Therefore, the origin of Hox genes and ParaHox genes occurred prior to the evolutionary split between the Cnidaria and the Bilateria and predated the evolution of the anterior-posterior axis of bilaterian animals. Our analysis also suggests that the central Hox class was invented in the bilaterian lineage, subsequent to their split from the Cnidaria. PMID:11324016

  10. Saturn’s Tropospheric Temperatures and Para-Hydrogen Distribution from Ten Years of Cassini Observations

    NASA Astrophysics Data System (ADS)

    Fletcher, Leigh N.; Irwin, Patrick G.; Sinclair, James; Giles, Rohini; Barstow, Joanna; Achterberg, Richard K.; Orton, Glenn S.

    2014-11-01

    Cassini/CIRS observations of Saturn’s 10-1400 cm-1 spectrum have been inverted to construct a global record of tropospheric temperature and para-hydrogen variability over the ten-year span of the Cassini mission. The data record the slow reversal of seasonal asymmetries in tropospheric conditions from northern winter (2004, Ls=293), through northern spring equinox (2009, Ls=0) to the present day (2014, Ls=60). Mid-latitude tropospheric temperatures have cooled by approximately 4-6 K in the south and warmed by 2-4 K in the north, with the seasonal contrast decreasing with depth. CIRS detected the north polar minimum 100-mbar temperatures 6-8 years after winter solstice, whereas the south polar maximum occurred 1-2 years after summer solstice, consistent with the lag times predicted by radiative equilibrium models. Warm polar cyclones and the northern hexagon persist throughout the mission, suggesting that they are permanent features of Saturn’s tropospheric circulation. The 200-mbar thermal enhancement (“knee”) that was strongest in the summer but weak or absent in winter in 2004-2006 (Fletcher et al., 2007, Icarus 189, p.457-478) has now shifted northward and is present globally in 2014, suggestive of radiative heating in Saturn’s tropospheric haze layer. Saturn’s para-H2 fraction, which serves as a tracer of both tropospheric mixing and the efficiency of re-equilibration between the ortho- and para-hydrogen states, is slowly altering: super-equilibrium conditions (para-H2 fraction exceeding equilibrium expectations and suggestive of subsiding airmasses) that dominated the southern summer hemisphere are now weakening, whereas the sub-equilibrium conditions (suggestive of uplift) of the northern winter are being replaced by equilibrium or super-equilibrium conditions in spring. The thermal ‘knee’ and the para-H2 distribution are tracking both the increased spring illumination and the increasing tropospheric haze opacity of the springtime hemisphere observed via colour changes in visible light, suggesting a close connection between the tropospheric temperatures, para-H2 and haze characteristics.

The protonation reaction of poly(para-arylenevinylene)-co-(meta- pyridylvinylene) with hydrochloric acid and the quaternization reaction of poly(2,5-dioctyloxy-1,4- phenylenevinylene)-co-(2,6-pyridylvinylene) with methyl triflate have been investigated by spectrophotometric and fluorescent methods. The absorption, excitation and fluorescence spectra of these copolymers as well as their corresponding model compounds were studied and compared. The photophysical properties of the investigated polymers suggest that these materials could be good candidates for the fabrication of efficient blue and green light-emitting diodes.

    1986-04-01

    Heat-capacity measurements of para-hydrogen adsorbed on graphite were performed recently and revealed an interesting phase diagram similar to 4He. We report a renormalization-group study based on a three-state Potts model with vacancies which approximates the experimental situation. The resulting global phase diagram is in a three parameter space of pair-interaction constants and chemical potential as studied by Berker, Ostlund and Putnam. The Lennard-Jones or other effective potential between the para-H 2 adsorbed molecules determines the subspace relevant to this adsorbate. A method to calculate thermodynamic densities is discussed and the resulting temperature versus density diagram agrees well with the experiment.

No existen políticas sistemáticas de atracción y retención de personal de salud en Ayacucho. Los principales incentivos, en orden de importancia, fueron mejoras salariales, oportunidades de formación y capacitación, estabilidad laboral y nombramiento, mejoras en infraestructura y equipos, e incremento del personal. Se mencionaron también mejoras en la vivienda y alimentación, mayor cercanía con la familia y reconocimiento por el sistema de salud. Existen coincidencias y singularidades entre los distintos grupos sobre los incentivos clave para estimular el trabajo rural, que deben considerarse al diseñar políticas públicas. Las iniciativas del Estado deben comprender procesos rigurosos de monitoreo y evaluación, para asegurar que las mismas tengan el impacto deseado. PMID:22488318

    We report on a ‘green’ method for the utilization of carbon dioxide as C1 unit for the regioselective synthesis of (E)-cinnamic acids via regioselective enzymatic carboxylation of para-hydroxystyrenes. Phenolic acid decarboxylases from bacterial sources catalyzed the ?-carboxylation of para-hydroxystyrene derivatives with excellent regio- and (E/Z)-stereoselectivity by exclusively acting at the ?-carbon atom of the C=C side chain to furnish the corresponding (E)-cinnamic acid derivatives in up to 40% conversion at the expense of bicarbonate as carbon dioxide source. Studies on the substrate scope of this strategy are presented and a catalytic mechanism is proposed based on molecular modelling studies supported by mutagenesis of amino acid residues in the active site.

El mismo será instalado en el foco primario de un reflector parabólico de 30 metros de diámetro que funcionará como radiómetro en el IAR. El receptor es del tipo polarimétrico, con lo cual permite la posibilidad de obtener las componentes de polarización lineal y circular. Para tal fin el cabezal constará de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia menor, (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor, además de tener características polarimétricas, podrá ser usado en el contínuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

    O detector de ondas gravitacionais Mario Schenberg está sendo projetado e construído pelo grupo Gráviton. Sua construção está ocorrendo no Laboratório de Estado Sólido e Baixas Temperaturas (LESBT) da Universidade de São Paulo, na cidade de São Paulo. Esse detector possui uma massa ressonante esférica de cobre-alumínio, com 65 cm de diâmetro, pesando aproximadamente 1150 Kg, suspensa por um sistema de isolamento vibracional, que se encontra em fase de testes preliminares. A real eficácia desse sistema, entretanto, só poderá ser comprovada quando o detector estiver aparelhado com, pelo menos, um transdutor eletromecânico de altíssima sensibilidade acoplado à massa ressonante. Neste momento, não só este sistema de isolamento vibracional será posto em teste, como o do projeto da fiação que transporta os sinais de microondas até os transdutores e destes para a pré-amplificação. Apesar dessa fiação ter sido projetada para não apresentar nenhum contato com a superfície esférica da antena, de maneira a não haver nenhuma transmissão de ruído vibracional do laboratório para esta, deve-se minimizar o ruído microfônico produzido nessa fiação por oscilações mecânicas, uma vez que ela não utiliza nenhum sistema de isolamento vibracional. Com o intuito de resolver este problema, projetamos uma estrutura, formada por pequenos cilindros conectados por barras, a qual não terá nenhuma ressonância mecânica na faixa de freqüências de interesse para detecção (3000 - 3400 Hz). Desta forma, as vibrações nessa faixa não serão amplificadas. O projeto foi feito usando iterativamente, de maneira a otimizar os resultados obtidos, o programa de elementos finitos Msc/Nastran. Através de simulações feitas neste programa, determinamos os parâmetros geométricos ideais a serem utilizados, os quais proporcionam a maior região espectral de interesse livre de ressonâncias.

    The direct, nucleophilic imidation of acetanilide derivatives has been performed under mild, iodine(III)-mediated or -catalyzed conditions, employing lithium triflimide as the nitrogen source. The reaction exhibits exclusive regioselectivity for the para position and shows a good tolerance for varied functional groups at both the ortho or meta positions. Preliminary mechanistic data suggest that the LiNTf2 reagent plays a key role in the reactivity. PMID:26095155

    A P450 catalyzed N-para-hydroxy metabolite was suggested to be a prerequisite for N-dephenylation occurrence. Although two mechanisms have been proposed to describe this process as a consequence of either a chemical degradation or P450 lead epoxidation of the hydroxy metabolite, direct evidence has not been demonstrated. In this study, we started with a novel technique using a dipeptide, Lys-Phe, to trap the byproduct of N-dephenylation, a quinone-like compound, forming a peptide adduct to facilitate LC/MS characterization. N-dephenylation via chemical degradation was assessed by LC/MS characterization of the resulting (Lys-Phe)(2)-quinone from 4-hydroxyphenyl-2-naphthylamine following interaction with Lys-Phe in pH 7.4 buffer. N-dephenylation mediated by P450 catalysis proposed was investigated in N-para-hydroxy benzodioxane derivative incubated with mouse liver microsomes in the presence of Lys-Phe in 50/50 H(2)(16)O/H(2)(18)O. LC/MS demonstrated that only one of two hydroxy oxygens in the byproduct was exchanged with water and the MS signal intensity of the (16)O labeled peptide adduct was equal to that of (18)O labeled. These observations suggested us that the origin of the oxygen in the byproduct was from water only, not from O(2). Therefore, it appears that N-dephenylation occurs via a stepwise process, namely the substrate is initially metabolized to a N-para-hydroxy metabolite by P450, which was readily oxidized to a quinone imine/iminium chemically or enzymatically, then hydrolyzed resulting in N-dephenylation. However, in our studies, the proposed P450 mechanism involving epoxidation of a N-para-hydroxy metabolite was disproved. PMID:16925518

    DNA replication in Bacillus subtilis is reversibly inhibited by 6-(para)-hydroxyphenylazouracil (HpUra) (1971), whereas replication of temperature phage SPO2 is not affected by the drug. Experiments are presented which show that HpUra will induce bacteria lysogenic for SPO2. Also, prophage ?105, which is sensitive to the drug, is induced by HpUra. Induction of SPO2 lysogenics in the presence of HpUra gives selective synthesis of SPO2 DNA. PMID:4214948

  17. Theoretical study of the design of a catalyst for para to ortho hydrogen conversion

    1992-01-01

    The theory of Petzinger and Scalapino (1973) was thoroughly reviewed, and all of the basic equations for paramagnetic para to ortho hydrogen catalysis re-derived. There are only a few minor phase errors and errors of omission in the description of the theory. Three models (described by Petzinger and Scalapino) for the rate of para to ortho H2 catalysis were worked out, and uniform agreement obtained to within a constant factor of 2 pi. The analytical methods developed in the course of this study were then extended to two new models, which more adequately describe the process of surface catalysis including transfer of hydrogen molecules onto and off of the surface. All five equations for the para to ortho catalytic rate of conversion are described. The two new equations describe the catalytic rate for these models: H2 on the surface is a 2-D gas with lifetime tau; and H2 on the surface is a 2-D liquid undergoing Brownian motion (diffusion) with surface lifetime tau.

    The conformational analysis of the para-menthane (PM) and 1,2,4-trihydroxy-para-menthane (TPM) is performed using the quantum chemical density functional theory (DFT) and ab initio Møller-Plesset perturbation theory up to the second order (MP2). In TPM, three hydroxyl groups generate eight stereoisomers comparing to the four para-menthane stereoisomers. From the thermodynamics point of view, the most preferred conformations show the chair-shaped configuration of the cyclohexane ring. The obtained energy barriers for the isopropyl group rotation in the chair-shaped stereoisomers are between 35 and 45 kJ mol-1. The crystal structure as well as the solvated TPM stereoisomer isolated from the Tea tree oil, Melaleuca alternifolia (Maiden & Betche) Cheel, were investigated experimentally. Isolated stereoisomer corresponds to the most energetically preferred conformation and the calculated structural data agree very well with the results from the X-ray and nuclear magnetic resonance measurements. Finally, the influence of the conformation and the presence of the intramolecular hydrogen bonds on the homolytic Osbnd H bond dissociation enthalpies and proton affinities were also discussed with respect to the simple alcohols (methanol, iso-propanol, iso-pentanol, tert-butanol, cyclohexanol) and phenol.

    DNA profiling through the analysis of STRs remains one of the most widely used tools in human identification across the world. Current laboratory STR analysis is slow, costly and requires expert users and interpretation which can lead to instances of delayed investigations or non-testing of evidence on budget grounds. The ParaDNA(®) Intelligence System has been designed to provide a simple, fast and robust way to profile DNA samples in a lab or field-deployable manner. The system analyses 5-STRs plus amelogenin to deliver a DNA profile that enables users to gain rapid investigative leads and intelligent prioritisation of samples in human identity testing applications. Utilising an innovative sample collector, minimal training is required to enable both DNA analysts and nonspecialist personnel to analyse biological samples directly, without prior processing, in approximately 75min. The test uses direct PCR with fluorescent HyBeacon(®) detection of STR allele lengths to provide a DNA profile. The developmental validation study described here followed the Scientific Working Group on DNA Analysis Methods (SWGDAM) guidelines and tested the sensitivity, reproducibility, accuracy, inhibitor tolerance, and performance of the ParaDNA Intelligence System on a range of mock evidence items. The data collected demonstrate that the ParaDNA Intelligence System displays useful DNA profiles when sampling a variety of evidence items including blood, saliva, semen and touch DNA items indicating the potential to benefit a number of applications in fields such as forensic, military and disaster victim identification (DVI).

    We have computed extensive grids of models of both C- and J-type planar shock waves, propagating in dark, cold molecular clouds, in order to study systematically the behaviour of the ortho:para-H_2 ratio. Careful attention was paid to both macroscopic (dynamical) and microscopic (chemical reactions and collisional population transfer in H_2) aspects. We relate the predictions of the models to observational determinations of the ortho:para-H_2 ratio using both pure rotational lines and rovibrational lines. As an illustration, we consider ISO and ground-based H_2 observations of HH 54. Neither planar C-type nor planar J-type shocks appear able to account fully for these observations. Given the additional constraints provided by the observed ortho:para H_2 ratios, a C-type bowshock, or a C-type precursor followed by a J-type shock, remain as plausible models.
