    2013-02-01

    Traumatic cataract is due to lens damage when mechanical, irradiative, electrical or chemical agents injury the globe. The appearance of a traumatic cataract is typically short and unilateral with rare spontaneous resolution and often involves other ocular anatomical areas. Medico-legal evaluation of the appearance and the consequences of a traumatic cataract requires a correct methodological approach with the support of qualified ophthalmological competences.

    There is a crisis in the field of medico-legal death investigation! This medical practice is one that most physicians do not think about until they are called in the middle of the night and informed that their patient has died and medical history is requested. Worse still, the trauma surgeon may need to explain why the patient did not survive the life-saving techniques used at his or her medical institution. The worst-case scenario is when the clinician is hit with a malpractice lawsuit. PMID:11837352

  3. MedicoPort: a medical search engine for all.

    2007-04-01

    We present a new next generation domain search engine called MedicoPort. MedicoPort is a medical search engine designed for the users with no medical expertise. It is enhanced with the domain knowledge obtained from Unified Medical Language System (UMLS) to increase the effectiveness of the searches. The power of the system is based on the ability to understand the semantics of web pages and the user queries. MedicoPort transforms a keyword search into a conceptual search. Through our system we present a topical web crawling technique and indexing techniques empowered by the semantics information. MedicoPort aims to generate maximum output with semantic value using minimum input from the user. Since MedicoPort is designed to help people seeking information about health on the web, our target users are not medical specialists who can effectively use the special jargon of medicine and access medical databases. Medical experts have the advantage of shrinking the answer set by expressing several terms using medical terminology. MedicoPort provides the same advantage to its users through the automated use of the medical domain knowledge in the background. The results of our experiments indicate that, expanding the queries with domain knowledge, such as using the synonyms and partially or contextually relevant terms from UMLS, increase dramatically the relevance of an answer set produced by MedicoPort and the number of retrieved web pages that are relevant to the user request.

  4. Medico-legal aspects of histopathology practice.

    2001-06-01

    Medico-legal problems experienced by histopathologists differ from those of other clinicians as they are rarely in direct contact with patients. Nevertheless, the pathologist owes a duty of care to the patient and is liable for medical negligence. In the absence of local guidelines, it is prudent to follow guidelines published by learned Colleges elsewhere. This is also true when delegating duties to non-pathologists, technical and other support staff. Errors in diagnosis and documentation pose the most common problems in histopathology. In this, liability also depends on many factors including the provision of adequate clinical information by clinicians and competence of laboratory staff. Clinicopathological discussions, participation in quality assurance programmes and adherence to standard operating procedures are important audit activities to minimize and detect errors as well as prevent grievous outcome to patients. Issues also arise over the retention of specimens and reports. In general, wet, formalin-fixed tissues should be kept until histopathological assessment is finalized and preferably after clinicopathological sessions, and even longer if there is potential litigation. Reports should be archival. Paraffin blocks should be kept for at least the lifetime of the patient, and histology slides for at least 10 years, to facilitate review and reassessment. Despite adverse publicity in the foreign press over the use of human organs and tissues for research and education, it is accepted that processed tissues can be used for research and educational purposes provided the patient's identity is kept confidential. Nevertheless, it would be prudent to revise consent forms for surgery and autopsies to include the possibility that tissues removed can be stored or used for research and education. Good medical practice in pathology encourages a willingness to consult colleagues when in doubt, but advises that the treating clinician be informed if histopathological

    This study aims to review phytol (PYT), through published articles, periodicals, magazines and patents, which were retrieved from the PM, SD, WS, SP; DII, WIPO, CIPO, USPTO and INPI databases. Among the 149 articles and 62 patents, 27.52% articles and 87.09% patients were found on the searched topic, PYT and its sources and synthesis and metabolism; then followed by 15.44% and 14.77% articles on PYT in cytotoxicity/cancer/mutagenicity/teratogenicity and PYT in neurological diseases, respectively. In the pharma-medico viewpoint, PYT and its derivatives have been evident to have antimicrobial, cytotoxic, antitumorous, antimutagenic, anti-teratogenic, antibiotic-chemotherapeutic, antidiabetic, lipid lowering, antispasmodic, anticonvulsant, antinociceptive, antioxidant, anti-inflammatory, anxiolytic, antidepressant, immunoadjuvancy, hair growth facilitator, hair fall defense and antidandruff activities. Otherwise, the important biometebolite of PYT is phytanic acid (PA). Evidence shows PA to have cytotoxic, anticancer, antidiabetic, lipid lowering and aniteratogenic activities. In addition, it may be considered as an important biomarker for some diseases such as Refsum's Disease (RD), Sjögren Larsson syndrome (SLS), rhizomelic chondrodysplasia punctata (RZCP), chronic polyneuropathy (CP), Zellweger's disease hyperpipecolic academia (ZDHA) and related diseases. Thus, phytol may be considered as a new drug candidate. PMID:26296761

    Abuse of anabolic steroids is an increasing problem not only among athletes but also body-builders and teenagers. A fast-developing black market has been established since the opening of the borders to eastern Europe. Medico-legal aspects of doping are addressed with particular reference to toxicology and pathology. Constituents of anabolic steroids bought on the black market were identified using gas chromatography/mass spectrometry; the products did not contain the expected ingredients in 35% of cases. Long-term effects and fatalities because of anabolic steroid abuse are reported here based on our own case material and a literature review. In our own cases, severe cardiovascular side-effects developed after long-term abuse of Dianabol (methandrostenolone) and Oral-Turinabol (chlordehydromethyltestosterone), i.e. myocardial infarction, stroke, organomegaly and/or severe atherosclerosis. The pathogenesis of cardiovascular complications (cardiotoxic effect, risk of atherosclerosis, thrombogenic risk) is discussed based on the available literature reports following fatal outcome after the abuse of anabolic steroids.

    Medico-legal death investigation in China has a long history that can be traced back to the Chhin era in the third century BC. We conducted a national study on the current medico-legal death investigation system in China. Our study showed that, at present, medico-legal death investigations in China are conducted by c. 12,000 forensic medical experts mainly within five relatively independent agencies: the police organizations, the prosecutors' offices, the departments/divisions of forensic medicine/science in medical colleges and universities, the Institute of Forensic Science in the Ministry of Justice, and the government or private forensic societies. Owing to China's large population and area, the medico-legal death investigation is largely based on the administrative divisions. There is a wide variation in the scope, extent, and quality of investigations among the agencies and at the different levels of county/district, municipal, and provincial governments. This article gives a general overview of medicolegal death investigation in modern China. PMID:21496020

    Body packing is the ingestion or insertion in the human body of packed illicit substances. Over the last 20 years, drug smuggling has increased global and new means of transport of narcotics have emerged. Among these, the most frequent one is the gastrointestinal tract: from mouth to anus, vagina, and ears. Cocaine is one of the most traded drugs, followed by heroin. Condoms, latex gloves, and balloons are typically used as drug packets for retention in the body. There are different radiologic modalities to detect illicit drugs in body packing: Plain radiography, computed tomography (CT), ultrasound, and magnetic resonance. Current protocols recommend the use of radiography to confirm packet retention and, in case of doubt, the use of abdominal CT scan with reduced mAs. In case of packet rupture, catastrophic effects can occur. Management of patients carrying packets of drugs is a recurrent medico-legal problem. To improve diagnostic accuracy and prevent hazardous complications, radiologists and emergency physicians should be familiar with radiologic features of body packing. The radiologist plays both a social and a medico-legal role in their assessment, and it should not be limited only to the identification of the packages but must also provide accurate information about their number and their exact location. In this review, we focus on diagnostic errors and medico-legal issues related to the radiological assessment of body packers. PMID:26063072

    2014-01-01

    Vitamin D is a particularly important sterol hormone and its effects beyond bone are increasingly recognized. Over the last decade clinical interest has grown in vitamin D, with increased recognition of deficiency and hence increased prescribing of vitamin D products. However, the increased prescription of vitamin D has generally been met with unlicensed vitamin D products which potentially expose the patient to clinical risk. This review discusses the issues relating to the clinical use of unlicensed vitamin D products, safety concerns that may arise from this, as well as discussing the medico-legal responsibilities of the prescriber and dispenser.

    The Sanskrit word Visŭcikă refers to a condition in which vitiated văta dŏşa causes pain like pricking with a needle over the body. It occurs in a person suffering with ajĭrna (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 Mahăhărata 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

    The medico-ecological state of Russian regions has been analyzed on the basis of statistical data. It is found that the incidence of different groups of diseases varies significantly in different regions. The regions of Russia are classified according to their medico-ecological parameters; the zones of maximal health risk caused by environmental pollutions, including air, water and soil pollution, are determined. The proposed methods for zoning by health level and the estimate of medico-ecological conditions in different administrative units provide the basis for the development of measures for the adaptation of population. These data can be used for the control of sanitary measures planned by regional organizations for the social-ecological protection of the population.

  14. [Prevention of medico-legal conflicts in medical practice].

    Minossi, José Guilherme

    2009-02-01

    Generally, medico-legal conflicts which occur in surgical and medical practice are a source of worry for both the medical profession and the society as a whole, because on one hand, they could cause high emotional stress for doctors, and on the other hand, patients could be rejected. Once consolidated, defensive medicine increases treatment costs and the doctor-patient relationship could transform into a tragedy. There are many causes for this, including non-treatment factors, such as an unsupported and disorganized health system, lack of participation from society and the doctor in improving this system, the training machine which launches a large number of young unprepared doctors to practice in this noble profession, along with a lack of continuing training, as there are few public or private institutions providing preparation, or further medical training. The related treatment factors are generally, a deficient doctor-patient relationship, poor work condition, power abuse by the doctor, a lack of clear agreement, and poor medical record keeping. These conflicts cannot be solved by simple creating legislation, or by denying the existence of medical error, which occurs at higher frequency than the actual conflicts. It is very important to improve the doctor-patient relationship because an effective fraternal relationship reduces the chance of a judicial demand. The doctor still needs to fully understand his/her conduct obligations and mainly to avoid power abuse. Doctors must also professionally link themselves with politicians who fight for the individual's rights against the system. Society must also understand that health is not just an issue exclusive for doctors, and people must fight to improve living conditions. Society must seriously show its frustration with the increasing disparity between scientific possibilities and actual wellbeing. The training machine needs immediate profound changes to produce professionals with the highest qualifications equipped

    Intra-partum (IP) surveillance of the unborn child by cardiotacography (CTG) monitoring is the commonest obstetric procedure in the developed world.(1) It is also the most medico-legally contested obstetric procedure in labour. In 2011, 'birth asphyxia' comprised 50% of the UK National Health Service (NHS) litigation costs,(2) and in the 2000-2010 decade, the same NHS paid out £3.1 billion for maternity medico-legal claims (the highest of any speciality), mostly involving cerebral palsy and CTG misinterpretation.(3) This article looks at a number of characteristics of IP CTG monitoring which argue for its questionable solidity of base in court proceedings.

    There is a dearth of literature on the extent of fetal or newborn abandonment or "dumping" and the medico-legal investigation procedures these cases require. This is despite the fact that these occurrences are a worldwide phenomenon and by definition involve criminal law concerns such as illegal abortion, concealment of birth, murder, or neonaticide, depending on the country concerned. This article contributes to current literature in both respects and provides a retrospective case audit for the period 2004-2008 pertaining to all abandoned newborns and fetuses admitted to the Pretoria Medico-Legal Laboratory (PMLL) in South Africa. Demographic details, scope, and nature of the medico-legal investigation as well as formulation of cause of death were recorded. A total of 289 cases were identified for inclusion in this study, 57% of which were considered to have been non-viable fetuses, while 45 of the viable fetuses were deemed to have been stillborn. These instances involve the crimes of concealment of birth and at times illegal abortion, yet prosecution of these cases are relatively unheard of. Signs of live birth were identified in 38 of the cases in the study. Of these infants, 9 were deemed to have died from injuries they have sustained, and in a further 9 cases, no anatomical cause of death could be identified. Homicidal cases should be brought in cases where death ensued as a result of abandonment; however, it is not known how many cases were prosecuted. A comparatively large number of cases were found to have been admitted to the Pretoria Medico-Legal Laboratory. This is alarming because South African abortion laws are liberal and services are free at point of access in the public health care sector. A substantial percentage of cases of abandoned infants were found to have shown signs of life after birth implying a homicidal manner of death or death by abandonment, but it seems these cases are merely shelved.

    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

    Despite the increasing implementation of standardized rape kits across jurisdictions, the medico-legal findings generated by these tools are often not related to positive criminal justice outcomes. Given that there has been no global investigation of the factors that might impede their successful use in cases of sexual assault, we conducted a review of relevant scholarly and "grey" literature from industrialized and less-developed regions. One key theme to emerge from the analysis concerned certain problematic practices and behaviors of professional groups involved in the various stages of the post-sexual assault process. We found that a lack of competence in handling sexual assault cases, contempt for women who have been victimized, and corruption among some forensic examiners, police, scientists, and legal personnel often have shaped the collection, processing, analysis, and use of medico-legal evidence. We discuss recent initiatives and future directions for research that might serve to address these issues. PMID:23935160

    The care of older people in residential aged care services could be improved by optimising the use of existing information gathered for medico-legal death investigations. The authors address three myths contributing to underuse of this information: deaths are not preventable; public health gains are too small; and it is someone else's charter or responsibility A significant proportion of deaths are preventable, specifically those occurring prematurely from natural causes or due to injury and trauma. By addressing these preventable deaths, significant public health cost savings and better health outcomes for our growing ageing population can be achieved. Despite substantive monitoring of the provision of aged care, no single entity is explicitly responsible for systematically analysing medico-legal death information. The data and skills for using information from medico-legal death investigations currently exist. Dispelling the myths removes one impediment to investing in this area of public health.

    Infertility has existed for thousands of years and treatment has evolved with the advance of medical science. Surrogate parenthood was effected previously by sexual intercourse, but AIH, AID and GIFT have rendered this practice obsolete. The terms surrogate mother, partial and full surrogacy are defined.

    PubMed

    De Renzi, Silvia

    2002-06-01

    Studying early modern medico-legal testimonies can enrich our understanding of witnessing, the focus of much research in the history of science. Expert testimonies were well established in the Roman Cannon law, but the sphere of competence of expert witnesses - one of the grounds on which seventeenth-century physicians claimed social and intellectual authority- troubled contemporary jurists. By reconstructing these debates in Counter Reformation Rome, and by placing in them the testimonies given by Poalo Zacchia, one of the founding fathers of legal medicine, this article discusses the epistemological and social issues surrounding the definition of expertise about the body in court. It shows how a high-ranking expert witness would define his competence versus the legal authority on the one hand, lower-status expert witnesses on the other. But it also explores the interactions between specific legal constraints, for example about eye witnessing, and the ways in which different kinds of witnesses would use the body as a source of evidence for testimony. While engaging with medico-legal issues including the ambiguous signs of childbirth and the (in)visibility of pain, the article examines their meanings within Counter Reformation social controversies, including control over sexuality, imposition of discipline and the social status of physicians.

    An Oral and Maxillofacial surgeon at any time during the practice will encounter medicolegal cases (MLC). There are lacunae in the knowledge and understanding of the correct method of dealing with such cases. Many of the practitioners are apprehensive and anxious as they have to interact with individuals and systems outside the normal realm of practice. In today's arena, it is of utmost importance to be aware of legal system and law of the land. An OMF surgeon needs to have thorough understanding in recording and maintenance of the details of all MLCs and presenting the same in the court. Professional guidelines for expert witness are often not well recognised as those relating to the clinical practice. Surgeon has an obligation to conduct him/herself to highest ethical standards. This article provides insight into the details of registration of MLC, examination and recording of injuries, collecting medico-legal evidences and writing a medico legal report. Also discusses the court proceedings and possible questions that may be faced by the surgeon in the court. PMID:26604471

    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

    Whiplash injury medico-legal reporting has traditionally been focused upon identifying restrictions in range of motion and identifying the presence of tender areas in the cervical spine in an effort both to diagnose the condition and to offer a prognosis. There have been considerable advances in this field over the last decade however that calls into question such a diminutive approach. This paper reviews the contemporary evidence base for the medico-legal assessment of whiplash injury and identifies a body of literature that strongly implicates a Claimant's physiological and psychological stress response as a key medico-legal marker in predicting prognosis following whiplash injury.

    2016-03-21

    Capturing clinical images is becoming more prevalent in everyday clinical practice, and dermatology lends itself to the use of clinical photographs and teledermatology. "Store-and-forward", whereby clinical images are forwarded to a specialist who later responds with an opinion on diagnosis and management is a popular form of teledermatology. Store-and-forward teledermatology has proven accurate and reliable, accelerating the process of diagnosis and treatment and improving patient outcomes. Practitioners' personal smartphones and other devices are often used to capture and communicate clinical images. Patient privacy can be placed at risk with the use of this technology. Practitioners should obtain consent for taking images, explain how they will be used, apply appropriate security in their digital communications, and delete images and other data on patients from personal devices after saving these to patient health records. Failing to use appropriate security precautions poses an emerging medico-legal risk for practitioners. PMID:26985853

    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.

    Idiopathic pulmonary haemosiderosis is a rare disorder characterised by repeated episodes of intra-alveolar bleeding in association with consecutive anaemia, pulmonary fibrosis, pulmonary hypertension and respiratory failure. Pregnancy may exacerbate the symptoms of idiopathic pulmonary haemosiderosis typically worsening in the third trimester. A 32-year-old female after delivery was admitted to hospital with progressive dyspnoea of about 1-month duration. Sudden circulatory collapse caused fatal complication. During the post-mortem investigation, lung haemorrhage and histologically abundant iron deposition in macrophages and interstitial fibrosis were found. Medico-legal post-mortem evaluation of fatal cases may support the clinico-pathological context of the diagnosis of this entity. PMID:22281220

    Endoscopic endonasal sinus surgery represents the overall accepted type of surgical treatment for chronic rhinosinusitis. Notwithstanding raised and still evolving quality standards, surgeons performing routine endoscopic interventions are faced with minor complications in 5% and major complications in 0.5–1%. A comprehensive review on all minor and major complications of endoscopic surgery of the paranasal sinuses and also on the anterior skull base is presented listing the actual scientific literature. The pathogenesis, signs and symptoms of each complication are reviewed and therapeutic regimens are discussed in detail relating to actual publication references. Potential medico-legal aspects are explicated and recent algorithms of avoidance are mentioned taking into account options in surgical training and education. PMID:24403974

    Foeticide and the abandonment of newborns are important, albeit frequently neglected, issues. Concealment of childbirth is often seen in the setting of unwanted pregnancy which has been recognised as one of the most important factors in both cases. This study highlights the medico-legal autopsy findings of 238 abandoned foetuses and newborns over a period of 17 years (1996-2012) from the region of South Delhi, India. There was no sex predilection. The majority of the cases were full term. Nearly 35% of the foetuses were still born, about 29% were live born and the remainder were non-viable. Among the live born, death by homicide was more common than a natural death and most were left by the roadside. The abandoning and killing of newborns needs urgent attention, and strict measures are needed to save thousands of innocent lives. PMID:26857075

    Percutaneous suture closure devices have reduced the time needed for manual compression and hospital stays, but several meta-analysis emphasized a higher risk of vascular damages compared to manual compression. Two cases of infections on percutaneous suture closure devices were analyzed; which had medico-legal issues. Beyond the medical point of view, the patient's complaints, the way lawyers and medical experts have examined the cases were analyzed and resulted in physicians and hospitals being sentenced. Rather than stigmatizing those devices, we just want to invite cardiologists not to underestimate this serious risk. Before using those devices, physicians should balance the risk-benefit ratio, follow prevention guidelines, and most of all, be aware of any single signs of emerging infection to detect and treat them early, and thus reduce the severity of infections thanks to a targeted antibiotic treatment adapted to the antibiogram and an active role of vascular surgeons.

    2015-03-01

    The medico-legal aspects of the dental management of ageing and aged patients relate mainly to the assessment of the patient's competence and the role of substitute decision makers. Dentists will assess whether or not a patient is competent to give informed consent to treatment. Lawyers use the word 'capacity' when deciding whether a person can make an important decision about their life. Competence and capacity mean the same thing. Assessment of competence and the role of substitute decision makers rests firmly on a sound understanding of the ethical basis of dental practice. This article will discuss the ethical basis of dental practice; the assessment of competence and the gaining of informed consent; the role of substitute decision makers and the nature of the decisions that are made at the end of life.

    This communication highlights some of the ethical and possible legal responsibilities which pertain to the taking, reading, reporting, and communication of findings from cone-beam computed tomography (CBCT) scans. The importance of knowledge of head and neck anatomy and pathology to reduce the likelihood of incorrect interpretation is emphasised. Failure to detect critical findings in any diagnostic image can potentially result in medico-legal consequences. CBCT is no exception to this rule. Dental schools are advised to include CBCT imaging as a diagnostic tool in their under- and postgraduate curricula thereby equipping graduates to use 3D imaging in general and CBCT in particular. Existing dental practitioners are advised to seek continuing education on 3D imaging as part of their required lifelong learning. PMID:23971277

    Based on our experiences with medico-legal autopsies, we analyzed traumatic injury of the vertebrobasilar artery (VBA) in traffic accident victims. VBA rupture occurred in six cases with traumatic medullary lesions, but in none with cervical cord injury. A relatively small external force applied to the head or neck can induce isolated traumatic subarachnoid hemorrhage (SAH), which accounts for approximately 11% of fatal head injuries. We examined the relationship between site of impact and site of vascular injury in 16 cases of isolated traumatic SAH. The results showed that the vertebral artery (VA) on the side of impact tended to be longitudinally injured in victims experiencing an external force equivalent to that of a fist punch to the head or face. There was no clear relationship between the site of impact and the site of vascular injury in victims who had sustained an external force greater than that of a fist punch. However, our results suggest that an external force causing rotation of the head was likely to cause tearing of the artery. In cases in which an external force equivalent to that of a fist punch was applied to the head, a raised blood alcohol level was a significant risk factor for artery rupture. Furthermore, a difference in the diameters of the left and right VAs was a risk factor for artery rupture. To determine why the VA, the most frequent site of arterial dissection, is also frequently the site of injury, we histologically examined normal and dissected VBAs. We also discuss medico-legal issues of the causal relationship between external force applied and rupture or dissection of the VA. PMID:16308512

    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

    Man's olfactory perception is considerably limited compared to that of other animals; this sense is, however, extremely important in our social lives: it helps us to "savour" our food, it enables us to appreciate perfumes and, even more important, to pick up smells that signal a danger, such as a gas leak or a fire. We describe the clinical case of a patient with anosmia and hypogeusia that appeared immediately after suffering a concussive head injury. We go through the diagnostic protocol for medico-legal assessment of hypoanosmias previously described in the literature, which includes a clinical and an imaging section. In 9% of all anosmic patients, a traumatic event precedes the onset of the disorder, with repercussions on the olfactory channels and centres of the peripherical and/or central nervous system. The overall rate of anosmia following head injury is estimated to be around 7.5%. Among the principal causes of anosmia, those of medico-legal interest constitute 35% of the total. On the basis of our personal experience and of clinical studies conducted by other Authors, we propose that a bioptic investigation of the olfactory mucosa be added to the existing protocol. The olfactory neuroepithelium of patients suffering from post-traumatic anosmia, in fact, evidences some characteristic degenerative aspects. In conclusion, we report several comments regarding the quantification of the reduction of the olfactory function in different areas of medico-legal interest. PMID:12173284

    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

    Aśvattha (Ficus religiosa Linn.) is a tree which has got mythological, religious and medicinal importance in Indian culture since ancient times. As per Vedic Index Aśvattha means horse stand, a place or site or an object where or under which horses stand. Aśvattha 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. Atharvavĕda associates it with the third heaven. It discusses medicinal properties of Aśvattha along with Soma and Kuştha. Aśvattha is associated with the triad of Gods-Brahma, vişņu and siva. Reference to Aśvattha is found in Rămăyaņa, Mahăbhărata, Bhagavadgĭta, Buddhistic literature, Arthaśăstra, Purănăs, Upanişads etc. non-medical literature also. According to Ayurvĕda it has several synonyms. Most of them symbolize its sacredness. Aśvattha 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.

    Blunt trauma from accidental falls or intentional jumping from great heights occurs frequently in forensic medicine. The goal of this study was to investigate injuries due to falls in children under 19 years of age. Injuries from falls are the leading cause of visits to emergency departments and to deaths due to injuries. Various methods are used in the classification of falls. In this study, we have classified falls as "high-level" (≥ 5 m), "low-level" (<5 m) and "ground-level". We have retrospectively evaluated 814 boys (61.18%) and 512 girls (38.62%), making up a total of 1326 children (under 19 years old) with the mean age of 7.85 ± 3.46, that were admitted to State Hospital between January 2009 and December 2013 due to falls from heights and falls on ground-level. Falls were low-level in 738 cases, high-level in 176 cases, and ground-level in 412 cases. Cases were categorized by gender, age, age group, fall height, Glasgow Coma Scale (GCS), injured body part(s), mortality rate, and distribution according to months. In conclusion, falls merit attention because of their high risk of mortality and morbidity, as well as their burden on medical budgets. If the medico-legal aspects of falls were evaluated with regard to preventive event or death, the importance of the topic could be better understood. PMID:25735785

    Medico-legal notes in urologyIn recent years, claims for damages for medical liability have significantly increased. This implies that urologists need to know at least some basic concepts and updates regarding Forensic Medicine. Hence it is mandatory that, beyond the requirements of the law, every physician is covered by insurance liability for medical professionals. With the aim to protect and help the urologist in response to a claim for damages, the Italian Society of Urology has established and activated a "urological first aid", which any member can turn to in a moment of need. In the case of an accident, urologists can contact the "urological first aid" otherwise they can send a letter within 3 days to his/her insurance company, which will analyze the complaint and prepare a brief statement of defence and choose a civil lawyer specializing in medical professional liability. In this paper we will deal with some concepts of forensic medicine, distinguishing between public-liability and penal setting. PMID:25451877

    The study aimed to uncover the risk factors for the new defined pancreatic fistula (PF) and clinical related PF (CR-PF) after pancreaticoduodenectomy (PD) surgery and to evaluate the medico-economic effect of patients. A total of 412 patients were classified into two groups according to different criteria, PF and NOPF according to PF occurrence: CR-PF (grades B and C) and NOCR-PF (grade A) based on PF severity. A total of 28 factors were evaluated by univariate and multivariate logistic regression test. Hospital charges and stays of these patients were assessed. The results showed that more hospital stages and charges are needed for patients in PF and CR-PF groups than in NOPF and NOCR-PF groups (P < 0.05). The excessive drinking, soft remnant pancreas, preoperative albumin, and intraoperative blood transfusion are risk factors affecting both PF and CR-PF incidence. More professional surgeons can effectively reduce the PF and CR-PF incidence. Patients with PF and CR-PF need more hospital costs and stages than that in NOPF and NOCR-PF groups. It is critical that surgeons know the risk factors related to PF and CR-PF so as to take corresponding therapeutic regimens for each patient. PMID:25788941

    Declaration of death is a diagnosis and it has legal consequences. While declaring death, there is a possibility of committing a medical error. The majority of irregularities in declaring an individual dead occur in emergency situations. When a physician declares death, he is released from the professional obligation of saving the individual's life. The studies were based on the results of medico-legal evaluations in criminal cases in medical errors. In case death is erroneously declared, we may face a situation of squandering the chance of saving the life of a human being. Exposure to loss of life or to severe detriment to health are possible charges here, along with failure to offer medical assistance, although a deliberate character of the offence according to article 162 of the Polish penal code renders such a legal qualification dubious in case of medical errors. In both cases verification is needed whether an interest protected by law was still in existence, i.e. whether the individual was still alive when the physician incorrectly declared him dead.

    Abdomino-pelvic region is vulnerable to injury in various forms of trauma. This study was undertaken with objectives to study the pattern and type of external and internal abdominal and pelvic injuries and to identify the risk organs in abdomen and pelvis susceptible to trauma among the medico-legal autopsies at the mortuary of a referral centre in eastern Nepal during the period of one year (n = 80). Males constituted 80% of the cases and the mean age of the victims was 30.76 years. The cause of trauma was Road Traffic Accident in 82.5%. The manner of death was accidental in 87.5% and homicidal in 11.25% cases. Liver (57.5%) was the most common organ injured followed by spleen in 37.5% cases. Multiple organs injury was seen in 67.5% and absence of any external injuries was noted in 31.25% cases. Autopsy can play a role in establishing the missed injuries and be helpful to widen the knowledge of the medical faculty in early diagnosis and management of such injuries. PMID:23910883

    Background Health services for victims of rape are recognised as a particularly neglected area of the health sector internationally. Efforts to strengthen these services need to be guided by clinical research. Expert medical evidence is widely used in rape cases, but its contribution to the progress of legal cases is unclear. Only three studies have found an association between documented bodily injuries and convictions in rape cases. This article aims to describe the processing of rape cases by South African police and courts, and the association between documented injuries and DNA and case progression through the criminal justice system. Methods and Findings We analysed a provincially representative sample of 2,068 attempted and completed rape cases reported to 70 randomly selected Gauteng province police stations in 2003. Data sheets were completed from the police dockets and available medical examination forms were copied. 1,547 cases of rape had medical examinations and available forms and were analysed, which was at least 85% of the proportion of the sample having a medical examination. We present logistic regression models of the association between whether a trial started and whether the accused was found guilty and the medico-legal findings for adult and child rapes. Half the suspects were arrested (n = 771), 14% (209) of cases went to trial, and in 3% (31) of adults and 7% (44) of children there was a conviction. A report on DNA was available in 1.4% (22) of cases, but the presence or absence of injuries were documented in all cases. Documented injuries were not associated with arrest, but they were associated with children's cases (but not adult's) going to trial (adjusted odds ratio [AOR] for having genital and nongenital injuries 5.83, 95% confidence interval [CI] 1.87–18.13, p = 0.003). In adult cases a conviction was more likely if there were documented injuries, whether nongenital injuries alone AOR 6.25 (95% CI 1.14–34.3, p = 0

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

    Desmoid tumor is a fibroproliferative neoplasm with an intermediate malignancy and it can be localized in every bodily district: some locations are considered exceptional, like the urogenital localization. The Author point out a rare case of giant idiopathic scrotal fibromatosis that was found during an autopsy. A widower, that lived alone in poor hygienic conditions, was found dead in his house. The Judicial Authority ordered the autopsy, that was performed two days later at the Medico-Legal Section of Milan University. External examinations revealed only the considerable dimension of the scrotum (cm 24 × 41). The cause of death was fixed in a cardiac tamponade due to a natural heart laceration localized in correspondence of a transmural infarction. The toxicological exam resulted negative, while the histopathological and immunohistochemical analysis qualify the scrotal mass as a desmoids tumor. Due to the absence of predisposing conditions and of fibroproliferative infiltration in bladder and retroperitoneal space, the neoplasm was configured as an idiopathic desmoid tumor. The presented case gives the reason for the discussion concerning medico-legal aspects that are typical of rare neoplasms. PMID:26786144

    The participants in round table 6 of the Giens Workshops 2012 drafted recommendations based on the collective interpretation of important elements of the decree concerning the medico-economic evaluation of health products published a few days earlier (02 October 2012). The medico-economic evaluation (MEE), becomes an additional determinant for fixing the prices of health products by the Health products economic committee (Comité économique des produits de santé, CEPS) via the hierarchisation of treatment strategies, and thus modifies the market access conditions. Limiting the analysis to medicinal products and medical devices for which a major, important or moderate improvement in the medical service rendered (ASMR) or of the expected service (ASA) has been requested and presenting a significant budget impact on the Social Security expenses, excludes health products with ASMR or ASA with a lower level requested which often create complex price fixing problems and often have a major budget impact. This latter concept remains to be defined in detail. The MEE envisaged for the first registration must include the need to confirm or refute the initial hypotheses especially concerning the actual position in the therapeutic strategy at the time of renewal of the registration. For the first registration, the conventional reference to European prices guaranteeing a minimum price to innovative medicinal products, the medico-economic models submitted by the industry to the French Drug Authority (Haute autorité de santé, HAS) must be used to guide the compilation of new data to be requested at the time of the registration renewal and to negotiate the level of the discounts in the framework of a price-volume agreement, if applicable. The MEE will allow comparing the result of the analysis to the model hypothesis at the time of the renewal of the registration, which may contribute to the renegotiation (either up or down) of the price of health goods.

    Body packing is a general term used to indicate the internal transportation of drug packages, mainly cocaine, heroin, amphetamines, and methamphetamine, within the gastrointestinal tract. We described two cases of accidental drug intoxication, observed over the last year period, with evidence of intracorporeal drug concealment. The first case concerned a body packer transporting 69 drug packages of heroin adulterated with piracetam. The second body packer transported 16 drug packages of cocaine adulterated with levamisole. For both cases, forensic examination and toxicological analysis of drug packages and biological samples were carried out. Authors also wants to highlight the main medico-legal issues that commonly arise in cases of suspected or ascertained body packers. PMID:27161917

    The most likely cause of complaint with prosthodontics is a denture that in some way fails to be accepted. A denture that does not perform as the patient expects can give rise to great disappointment and anger. The problem is that acceptance of a denture is not just a technical issue. Success depends on the individual's ability to tolerate and adapt to the denture. It is therefore essential to make the right assessment for the patient from the outset. This includes discovering the patient's priorities and establishing realistic expectations. With the aim of assisting the dental profession in identifying and avoiding medico-legal risks in removable dentures, this article sets out a systematic, diagnostic and collaborative approach to complete and partial denture assessment and treatment.

    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

This consensus document, which includes a step-by-step illustrated explanation of flow charts articulated in eight sequential steps and a comprehensive description of the ascertainment methodology and the criteria of evaluation, has been developed by an International Working Group composed of juridical and medico-legal experts and adopted as Guidelines by the International Academy of Legal Medicine (IALM).

    In the emergency care of a young girl presumed to be a victim of sexual assault and the treatment of the lesions discovered in the perineum and vulvo-vaginal tract, the paediatric surgeon must take into consideration the medico-legal aspects of the file right from the first approach to this young victim. It would actually be damaging to her if a paediatric surgeon reconstituted the perineal tissues, vulva and vagina "ad integrum" without carefully describing the lesions observed and without, whenever possible, taking good quality photographs to be kept in the case file to support the evidence of sexual assault, if a criminal procedure is filed. Similarly, as a complement to this assessment of the initial lesions, the surgeon must be able to establish an anatomical and functional assessment of the vulvo-vaginal tract after healing, to enable the experts appointed by the court to determine the basis for compensation of bodily damages related to the sexual assault and the expenses entailed by further plastic operations required by the sequelae of the genital lesions. The bases for a pretium doloris, future aesthetic, sexual and obstetric damages should also be indicated in any certificate given to the patient's family or to the court experts. Thus, if the surgeon participates indirectly in demonstrating evidence of the crime subject to penal sanction, he can help the victim in her parallel civil court action for compensation of her bodily damages before the repressive jurisdiction.

    Pathologists at veterinary diagnostic laboratories receive medico-legal cases from a variety of animal species for postmortem examination. A search of computerized records of the Animal Health Laboratory, University of Guelph, Guelph, Ontario, Canada from 1998 to 2010 identified 1706 medicolegal cases. These were categorized according to the history as criminal investigations, anesthetic-related deaths, insurance, litigation, malpractice cases, and regulatory cases. Statistically significant linear trends in the proportion of medicolegal cases for all animals and criminal cases for companion animals were identified over the 12 year period. Companion animals had significantly greater odds of being a medicolegal case in all categories except for insurance and regulatory cases, compared to noncompanion animals. Based on pathology reports for the 271 criminal cases, 43.1% were consistent with neglect, 29.2% were compatible with non-accidental injury, 4.80% were poisonings, 10.7% were deemed to be due to natural disease, and 11.43% were inconclusive.

    The family tragedy that results from a child who dies in a road traffic accident may be exacerbated by judicial consequences for the adult/parent driving the vehicle, carrying the child, or responsible for properly immobilising the child in the safety device that was used. The author presents two court cases of the road traffic accident deaths of two children under the age of five years. The two cases are presented using a methodological approach, which integrates competencies in other fields into the medico-legal aspects. An analysis of the two cases provides the opportunity to discuss the driver's responsibility to properly use child safety seat and to analyse and evaluate the efficacy and limits of child restraint systems. In the two cases, the responsibility for the application of a child safety device was excluded. It was confirmed that child protective devices are not always sufficient to avoid lesions or death in road accidents that occur with significant speed or other specific dynamics. PMID:26462201

    2011-01-01

    This study explores historical iatrosophia texts from Cyprus from a botanical and medico-pharmacological point of view focusing on remedies containing resins and gums. The iatrosophia are a genre of Greek medical literature of Byzantine origin and can be described as medicine handbooks which serve as therapeutic repositories containing recipes or advice. To extract and analyze information on plant usage in such sources – which are largely unedited texts and so far have not been translated – we investigate (i) the relationship of the iatrosophia to Dioscorides’ De Materia Medica as well as historic pharmaceutical books or standard texts on modern phytotherapy and (ii) the validity of the remedies by comparing them to modern scientific data on reported biological activities. In the six texts investigated 27 substances incorporating plant exudates are mentioned. They are obtained from over 43 taxa of higher plants and in particular are used to treat dermatological, gastrointestinal, and respiratory tract conditions. The comparison to historic pharmaceutical books and phytotherapy texts reflects the gradual decline of the use of plant exudates in Western medicine. While remarkable parallels to Dioscorides’ text exist, the non-Dioscoridean influence suggests a complex pattern of knowledge exchange. Overall, this resulted in an integration of knowledge from so far poorly understood sources. The comparison with bioscientific data reveals a fragmentary picture and highlights the potential of these unexplored substances and their uses. Where relevant bioscientific data are available, we generally found a confirmation. This points to a largely rational use of the associated remedies. Taken together, the iatrosophia are a valuable resource for ethnopharmacological and natural product research. Most importantly they contribute to the understanding of the development of herbal medicines in the (Eastern) Mediterranean and Europe. PMID:21772820

    Most likely, opium was the first narcotic substance discovered at the dawn of mankind. Contemporary drug abuse predominantly poses a social and clinical problem and encompasses among other aspects emergency procedures in cases of intoxication and treatment of addictions. On the other hand, this is also a problem of the judicial system, which implements the rule of apt punishment in criminal cases (rapes, robberies, drivers, production and trade in narcotic substances) and of the necessity of monitoring drug-associates deaths. In all drug-associated cases, investigative capabilities have increased with the introduction of extremely sensitive and specific analytical methods (GC-MS, LC/MS, HPLC/DAD) allowing for detection and identification of multi-component mixtures of xenobiotics found at low concentration levels in complex biological matrices. The history of the Krakow Department of Forensic Medicine dates back to the year 1877, since archival materials have been kept since that time. Isolated deaths resulting from morphine poisoning, mostly involving individuals employed in the health care sector, constituted the subject of medico-legal expert opinions starting at the beginning of the 20th century, but only the eighties did bring the need for multidirectional toxicological examinations of opiates and their metabolites in diversified biological and non-biological materials. The present report, in addition to the historical background of opiate addiction, discusses selected problems derived from published by Department reports on opiates, including cases of fatal intoxication, hair analysis of drug addicts in its various aspects, interactions in cases of poisoning and others.

    Aggressive behavior in traffic is a widespread phenomenon. Up to 90% of the population are involved in mild forms such as shouting or gesturing. More dramatic cases with injury to individuals affect at least 1100 people in the US annually. Certain factors such as a male sex, a young age and an urban residency have been identified to contribute to the likelihood of road rage. Central to this analysis is the determination of specific features regarding the conflicting parties, the crime scene and the injury pattern in violent offenses related to traffic. In a retrospective study spanning 10 years, cases of road rage-linked injuries were identified amongst patients at the Medico-Legal Center of the Institute of Legal Medicine in Hamburg, Germany. The data were digitized and then analyzed using descriptive statistics via SPSS. There are disproportionately large numbers of males (85.7%) and motorists (61.2%) amongst road rage perpetrators. Usually the conflicting parties have no prior relationship (89.7%). In 68.1% of the cases, the violence applied was exclusively physical. Objects were utilized in 31.0% of all cases, and in more than half (55.6%) of these cases the vehicle was used as a weapon. The resulting trauma in road rage is mostly blunt and applied to the face and the extremities. There are characteristic features regarding the demographics, time and place of incident, as well as severity and pattern of injury in road rage associated offenses. Identifying these factors may lead to appropriate measures in the reduction of road rage. PMID:26817969

    Background and Aims: “Injuries due to lethal weapons” has emerged as a subject of public discussion in Sri Lanka. This study was conducted to describe the nature and characteristics of injuries due to lethal weapons during civil strife and to compare those with injuries after civil strife. Methods: A cross-sectional study was conducted on patients reported with injuries caused by lethal weapons from 2004 to 2014. Periods before and after May 19, 2009 were considered as during and after civil strife periods, respectively. A total of 21,210 medico-legal examination forms were studied. Results: There were 358 (1.7%) injuries caused by lethal weapons. Of them, 41% (n = 148) were during and 59% (n = 210) were after the civil strife. During civil strife, 63% occurred during daytime (P < 0.05). Types of lethal weapons that caused injuries were sharp weapons (n = 282), explosives (n = 49), and firearms (n = 27). Of them, 32% of during and 01% of after civil strife were explosive injuries (P < 0.01). Regarding severity, 73% of during and 57% of after civil strife injuries were severe (P < 0.05). During civil strife, 34% injuries were in lower limbs (P < 0.01) and after civil strife, 37% were in upper limbs (P < 0.05). Conclusions: The presence of many similarities indicated that both groups learnt their basis in a society that breeds violence. During civil strife, more injuries occurred during daytime, to lower limbs by explosive weapons and after the civil strife during nighttime, to upper limbs by nonexplosive weapons. Nonexplosive lethal weapon use after civil strife needs further investigation to develop evidence-based interventions. PMID:27127743

  3. A contextual analysis of nervous force in medico-scientific and literary writings in English of the nineteenth and early-twentieth centuries.

    This study concerns the context of use of the term "nervous force," as it appears in scientific and literary publications in English over the course of the nineteenth century and the first two decades of the twentieth century. The context of use, loss, or waste of nervous force and the context of nervous force as an expression of an attribute are analyzed in 189 scientific and 105 literary writings. Both contexts appeared in literary writings, where nervous force expresses the attributes of strength, forcefulness, vigor, or energy and use, loss or waste of nervous force explains such nonmorbid conditions as why someone is tired or needs rest. Only the context of use-loss-waste appeared in the medico-scientific literature, but here it explained both nonmorbid conditions (for example, effects of old age) and morbid conditions (like epilepsy). Changes in the number of these references give insights into the medico-scientific and the literary disciplines. Discussions include why nervous force is associated with explanation of disease, the persistence of its use in this capacity, and its influence on a similar use in literary writings. PMID:25297565

    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.

    Decree No. 2012-1116 of 2 October 2012 on medico-economic assignments of the French National Authority for Health (Haute autorité de santé, HAS) significantly alters the conditions for accessing the health products market in France. This paper presents a theoretical framework for interpreting the results of the economic evaluation of health technologies and summarises the facts available in France for developing benchmarks that will be used to interpret incremental cost-effectiveness ratios. This literature review shows that it is difficult to determine a threshold value but it is also difficult to interpret then incremental cost effectiveness ratio (ICER) results without a threshold value. In this context, round table participants favour a pragmatic approach based on "benchmarks" as opposed to a threshold value, based on an interpretative and normative perspective, i.e. benchmarks that can change over time based on feedback.

    Seeking to understand the highly unfavorable conditions for the development of gay male theater in Sweden, this essay engages in a historical study of the national opening of Mart Crowley's The Boys in the Band at Malmö City Theatre in 1970. Propelled by a Foucauldian-inspired theoretical approach, it identifies the subtle, yet highly effective, measures of control that the, at the time, social democratic welfare state exercised over representations of homosexuality on stage. State representatives, who complied with the official political and medical doctrine that homosexuality was a mental illness and posed a potential threat to social stability, interfered at various levels of the production, including the rehearsal process and post-performance talks between cast members and audiences. This alliance between Swedish theaters and members of the medical, psychological, and sexological professions constituted a medico-artistic complicity that supervised and regulated early attempts of gay representation on stage.

    The bodies of socially isolated people may remain undiscovered in their own houses for prolonged periods. Occasionally the body is in situ for sufficient time to become skeletonised, or partially so. Medico-legal investigation of these cases is complicated by degradation and contamination of evidence. Thus, a multidisciplinary forensic investigation is recommended. The potential contributions of forensic pathology, anthropology, odontology and entomology are outlined here with reference to two cases that occurred in Victoria, Australia, in 2003. Forensic pathologists are often unable to determine the cause of death in skeletonised bodies, however, they may find evidence to support either a natural or unnatural mode of death, and they may describe skeletal pathology or trauma, and identify skeletal features to support radiological identification of the deceased. Anthropologists can provide supplementary evidence of skeletal trauma. Additionally, they can assess age, sex, stature and racial affiliation from skeletal remains. Odontologists can identify individuals through comparison with ante-mortem dental records; however, potential difficulties exist in identifying the treating dentist of a socially isolated person. Odontologists may also examine the teeth and oro-facial skeleton for trauma. Entomologists may estimate minimum death time and/or season of death. Entomological examination of insect remains may also confirm that a body has lain in situ for a considerable period. PMID:15939160

    Despite the fact that some criteria of medico-legal certification in criminal and civil proceedings have been established, there are still some topics which are controversial and thus require modification. This is also true of the notion of "permanent essential defacement". In the opinion of the authors, changes in social conventions that are occurring nowadays, as well as a highly diversified, subjective perception of esthetic values indicate the need for discussing a possible modification of the presently obligatory criteria. Apart from the assessment of posttraumatic changes, an important problem is posed by defining the notion of "a part of the body customarily open to the view ". Additionally, the authors bring up for discussion the issue of experts taking into consideration the age and sex of the victims while assessing damages. A separate problem lies in difficulties in assessing the degree of detriment to health because of defacement due to the fact that official tables for evaluating permanent or long-term detriment to health do not include relevant information.

    The detection of autochthonous aquatic bacteria in tissue samples from drowning cases is increasingly considered as an alternative approach to assist the medico-legal diagnosis of death by drowning. Bacteria belonging to the genus Aeromonas may be suitable candidates for this application as they are ubiquitous in natural aquatic environments but are generally not part of the human microbiota. The research aims of this study were (i) to develop a sensitive, specific and rapid screening and confirmation method for Aeromonas species in tissue samples and (ii) to evaluate aseptic sternal puncture as a post-mortem sample technique and bone marrow as an alternative matrix to provide evidence of death by drowning. The presence of Aeromonas in tissue samples was verified by cultivation using the selective media Ampicillin Dextrin Agar (ADA) and Ryan's Aeromonas Medium. The use of ADA medium was found most optimal for the sensitive, inexpensive and quick detection of aeromonads in human tissue samples. Positive culture plates were confirmed by harvesting all colonies for DNA extraction and subsequent PCR amplification using Aeromonas genus-specific primers. Aeromonads were detected in lung swab, blood and bone marrow of drowned bodies (n=3), but were negative in these three matrices for all negative controls (n=90) tested. Bone marrow proved to be a suitable alternative matrix and can be sampled post-mortem by an aseptic sternal puncture. In conclusion, this study confirms previous indications that aeromonads in cultures from blood of water bodies can be considered a potential marker for drowning. Given the fact that the number of immersed bodies (drowned and non-drowned) included in this study is statistically not significant, however, more tissue samples need to be investigated to confirm the validity of these methods to aid the diagnosis of death by wet drowning.

    Psychiatrists and medical historians Werner Leibbrand (1896 - 1974) and Annemarie Wettley (1913 - 1996) are amongst the most striking figures in the field of history of medicine. Leibbrand was appointed director of the "Heil- und Pflegeanstalt" in Erlangen shortly after the war. Fuelled by his own experiences of suppression and persecution during the Nazi era he promised to unearth the crimes and atrocities which had happened under watch of the Nazi regime. He was joined by Annemarie Wettley, who worked as a physician at the hospital and had developed an increasing interest in the history of medicine. In 1946 they published "Um die Menschenrechte der Geisteskranken" ("Human Rights of the Mentally Ill") about the "euthanasia" campaign of the Nazi regime. Although a number of substantial works followed, Leibbrand and Wettley failed to inform in more depth on crimes and atrocities, for instance killings of patients and forced malnutrition. Doubts and charges against Wettley regarding her role in dietary programmes at the Erlangen hospital and against Leibbrand regarding special expert's reports--both had a short-term arrest warrant--might have contributed to stagnation in their efforts. In 1953 Leibbrand accepted the offer of a chair at the University in Munich, Wettley followed and habilitated in history of medicine; in the year 1962 they married. Contacts and exchange amongst medico-historical experts shed light on developments during the post-war era; still, a critical and fundamental review of the crimes within the medical system of the Nazi regime did not take place during this time.

    While married female members of the Japanese aristocracy followed the ideal of bearing children, female Buddhist novices and ordained women, often belonging to the aristocracy themselves, had to abstain from sexual activity and reproduction in accordance with the ordination rules. Infertility was considered with disdain by the first group, whereas not bearing children was the utmost expression of leading a virtuous life for the second group. However, both groups were concerned with keeping their physical bodies healthy: some to become mothers, the others to live as nuns or religious sisters. Focusing on the early medieval period, this paper examines various sources to illuminate the ways in which women were cared for and the kind of views and ideas that informed this care. Instead of looking at the ancient methods of treatment through a modern "scientific" lens and sorting them into "proto-scientific" and "superstitious" categories, medico-ritual and religious views on the female body are explored as facets of the worldview prevalent in the period under consideration. Special attention is paid to relevant chapters of the first medical work produced in Japan, the Ishinpō, compiled by a court physician, Tanba no Yasuyori, in the late 10th century CE. The investigation of other sources, such as Buddhist legends and doctrinal texts, suggests that women were recommended to seek to overcome their femaleness altogether by transforming their female bodies into male bodies in order to reach ultimate "healing" in terms of salvation. In lay circles, however, the Buddhist divinities and other powerful deities were worshipped to ensure this-worldly "healing" in terms of successful procreation and continuation of the family line.

    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.

    The history of Switra is as old as the human civilization. The earliest medical literature has given the description of Switra in rgavĕda and Atharvavĕda. Switra is also narrated in Mahăbhărat and in Vinayapĭţika. A Roman physician known as Celsus first introduced the term Vitiligo in the second century A.D. Vitiligo is also known as Leucoderma. The history of psychosocial repercussion was described in Vedic literature and it is also found in our society. A population-based study was presented to understand the social implication of this disease. The detailed description of etiological factors and modalities of treatment is found in all ayurvĕdic classics. Bakuci (Psoralia cordifolia) is still continuing as a photosensitizing drug in the treatment of Switra from the time of Caraka. PMID:17333661

    Water exists as two nuclear-spin isomers, para and ortho, determined by the overall spin of its two hydrogen nuclei. For isolated water molecules, the conversion between these isomers is forbidden and they act as different molecular species. Yet, these species are not readily separated, and no pure para sample has been produced. Accordingly, little is known about their specific physical and chemical properties, conversion mechanisms, or interactions. The production of isolated samples of both spin isomers is demonstrated in pure beams of para and ortho water in their respective absolute ground state. These single-quantum-state samples are ideal targets for unraveling spin-conversion mechanisms, for precision spectroscopy and fundamental symmetry-breaking studies, and for spin-enhanced applications, for example laboratory astrophysics and astrochemistry or hypersensitized NMR experiments.

    The Drosophila para sodium channel α subunit was expressed in Xenopus oocytes alone and in combination with tipE, a putative Drosophila sodium channel accessory subunit. Coexpression of tipE with para results in elevated levels of sodium currents and accelerated current decay. Para/TipE sodium channels have biophysical and pharmacological properties similar to those of native channels. However, the pharmacology of these channels differs from that of vertebrate sodium channels: (a) toxin II from Anemonia sulcata, which slows inactivation, binds to Para and some mammalian sodium channels with similar affinity (Kd ≅ 10 nM), but this toxin causes a 100-fold greater decrease in the rate of inactivation of Para/TipE than of mammalian channels; (b) Para sodium channels are >10-fold more sensitive to block by tetrodotoxin; and (c) modification by the pyrethroid insecticide permethrin is >100-fold more potent for Para than for rat brain type IIA sodium channels. Our results suggest that the selective toxicity of pyrethroid insecticides is due at least in part to the greater affinity of pyrethroids for insect sodium channels than for mammalian sodium channels.

    Lymph nodes are the main pathway in the spread of gynaecological malignancies, being a well-known prognostic factor. Lymph node dissection is a complex surgical procedure and requires surgical expertise to perform the procedure, thereby minimising complications. In addition, lymphadenectomy has value in the diagnosis, prognosis, and treatment of patients with gynaecologic cancer. Therefore, a video focused on the para-aortic retroperitoneal anatomy and the surgical technique of the extraperitoneal para-aortic lymphadenectomy is presented. PMID:26435746

    Breast cancer is a leading source of malpractice claims for radiologists and gynecologists. Delay in or failure to diagnosis was the second most common cause for allegations of malpractice and failure to diagnosis breast cancer accounted for the majority of these claims. The amount paid in indemnity for such claims was only second to claims paid for neurologically impaired newborns. Issues involved in documentation and communication are reviewed with a focus on specific medical legal cases. Obstetrician gynecologists must remain cognizant of the potential for liability.

    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

  5. India's Medico-Pharmaceutical Inheritance from the Colonial Period.

    PubMed

    Singh, Harkishan

    2014-01-01

    The development of pharmacy in India did not make sufficient headway during the British colonial period. The status of the pharmaceutical inheritance from the colonial era may be summarized as follows: There were around one hundred qualified pharmacists. The Health Survey and Development Committee (1943-45) put the number at 75. The number of compounders was nearly 27,000. They were inadequately qualified and were not counted as pharmacists. A large number of them worked in governmental hospitals. But for some missionary hospitals there was hardly any institutionalized pharmacy else-where. The drug distribution was in the hands of chemists and druggists who were not professionally qualified. The provision of drugs largely remained a trade. The drug industry was in its infancy. The yearly turnover was just 100 million rupees for a country as vast as India. The Drugs Rules 1945 under the Drug Act 1940 had been formulated but their implementation was yet to be effected. Some groundwork had been done on legislation for the control of pharmacy but the bill had yet to be enacted. There were three pharmacy degree-awarding institutions. The Banaras Hindu University and the Panjab University had instituted B. Pharm. courses in 1937 and 1944, with yearly intake of 20 and 5 students, respectively. The L. M. College of Pharmacy at Ahmedabad, then with the Bombay University, had their first admissions in 1947. Two diploma-level pharmacy courses existed at the Madras Medical College and the Medical College, Vishakapatnam, in the Madras Presidency; the yearly intake was very small. The country's entire pharmaceutical legacy from the colonial rule portrays the poor state of pharmacy practice that came with independence. The higher status of pharmacy as seen today is the result of sustained efforts made over the last fifty years. The chemists and druggists of the earlier period were not a qualified group--they were more concerned with protecting their trade interests and lacked the professional component. Thus the development of the profession constituted a formidable task. Once it became evident that inadequate attention had been paid to the pharmaceutical component of the new health care system during the colonial period--within pharmaceutical circles during the early part of the twentieth century--change began to take place, with the establishment of the Drugs Enquiry Committee recognized as the most significant event of the time. The Report was submitted by the Committee in 1931, laying the foundation of the drugs and pharmacy statutes and development of the pharmacy profession in general. It was a coincidence that the year 1931 also witnessed an occurrence of potential significance; that was, the entry of Mahadeva Lal Schroff, a man with an indomitable spirit, into the pharmaceutical arena to lead and direct the making of modern pharmacy in India.

    Studies in ethnobotany and ethnozoology under the umbrella of Ethnobiology seem imbalanced in the sense that enormous publications have accumulated in case of the former but only little information has been disseminated in case of the latter. While 7500 wild plant species are known to be used by tribals in medicine, only 76 species of animals have been shown as medicinal resources (Anonymous, 1994). The present paper is the first-hand information of folklore medicine and animals in Mizoram. The animals enumerated comprise of 25 vertebrates and 31 invertebrates and are used for treatment of over 40 kinds of diseases or ailments, including jaundice, tuberculosis, hepatitis, cancer, asthma and veterinary disease. The author, however, does not recommend destruction of wild animals, be it for food or medicine. PMID:12585311

  7. Eugenic Sterilization: Medico-Legal and Sociological Aspects

    Robinson, Felipe C.; Robinson, Shirley W.; Williams, Loretta J.

    1979-01-01

    The court-ordered sterilization of a normal 18-year-old black female in North Carolina focused attention on the unfortunate impact of eugenic statutes that allow sterilization as a method of social control. The existence of these laws in many states allows misapplication and abuse of authority which, not infrequently, is directed liberally to blacks and other minority groups. Eugenic sterilization is, at this time, a legally accepted form of “medical treatment.” The justification of such sterilization is the vague concept that the presumed “mentally deficient” individual is probably a potential parent of socially inadequate offspring who would likewise be socially inadequate. Since there never has been factual substantiation of whether the sterilization of these individuals will diminish the incidence of mental retardation, it is necessary to focus attention on the concept of eugenic sterilization and point out its many fallacies.

    Certificates are acts meant to note facts of medical order. They constitute the proof of the bodily damage in a file of repair request. Only a doctor in medicine can write such a paper. The disciplinary, penal and civilian responsibility is committed every time that the doctor agrees to write a medical certificate. The medical secret must be respected when writing such a medical certificate. The document must be handed the patient. The dentist can establish certificates of different nature when he is asked by his patients, since the noted facts are part of his expertise. The certificate must be written after exam of the patient. The description of the lesions must be precise and complete. Under pain of nothing, the medical certificate must include: the identity of the doctor, the patient's one, the date of writing and the signature of the editor. The ITT show on the medical certificate is of great importance because it determines jurisdictions related to voluntary and involuntary violence. PMID:15074072

    The ParaScope parallel programming environment, developed to support scientific programming of shared-memory multiprocessors, includes a collection of tools that use global program analysis to help users develop and debug parallel programs. This paper focuses on ParaScope's compilation system, its parallel program editor, and its parallel debugging system. The compilation system extends the traditional single-procedure compiler by providing a mechanism for managing the compilation of complete programs. Thus, ParaScope can support both traditional single-procedure optimization and optimization across procedure boundaries. The ParaScope editor brings both compiler analysis and user expertise to bear on program parallelization. It assists the knowledgeable user by displaying and managing analysis and by providing a variety of interactive program transformations that are effective in exposing parallelism. The debugging system detects and reports timing-dependent errors, called data races, in execution of parallel programs. The system combines static analysis, program instrumentation, and run-time reporting to provide a mechanical system for isolating errors in parallel program executions. Finally, we describe a new project to extend ParaScope to support programming in FORTRAN D, a machine-independent parallel programming language intended for use with both distributed-memory and shared-memory parallel computers.

  16. Para-hydrogen perspectives in hyperpolarized NMR.

    PubMed

    Glöggler, Stefan; Colell, Johannes; Appelt, Stephan

    2013-10-01

    The first instance of para-hydrogen induced polarization (PHIP) in an NMR experiment was serendipitously observed in the 1980s while investigating a hydrogenation reaction (Seldler et al., 1983; Bowers and Weitekamp, 1986, 1987; Eisenschmid et al., 1987) [1-4]. Remarkably a theoretical investigation of the applicability of para-hydrogen as a hyperpolarization agent was being performed in the 1980's thereby quickly providing a theoretical basis for the PHIP-effect (Bowers and Weitekamp, 1986) [2]. The discovery of signal amplification by a non-hydrogenating interaction with para-hydrogen has recently extended the interest to exploit the PHIP effect, as it enables investigation of compounds without structural alteration while retaining the advantages of spectroscopy with hyperpolarized compounds [5]. In this article we will place more emphasis of the future applications of the method while only briefly discussing the efforts that have been made in the understanding of the phenomenon and the development of the method so far.

    Exposure to hair dye is the most frequent route of sensitisation to para-phenylenediamine (PPD), a common contact allergen. International studies have examined the profile of PPD, but Australian-sourced information is lacking. Patients are often dissatisfied with advice to stop dyeing their hair. This study examines patients' characteristics, patch test results and outcomes of PPD allergy from a single Australian centre, through a retrospective analysis of patch test data from 2006 to 2013 at the Liverpool Hospital Dermatology Department. It reviews the science of hair dye allergy, examines alternative hair dyes and investigates strategies for hair dyeing. Of 584 patients, 11 were allergic to PPD. Our PPD allergy prevalence rate of 2% is at the lower end of international reported rates. About half these patients also react to para-toluenediamine (PTD). Affected patients experience a significant lifestyle disturbance. In all, 78% tried alternative hair dyes after the patch test diagnosis and more than half continued to dye their hair. Alternative non-PPD hair dyes are available but the marketplace can be confusing. Although some patients are able to tolerate alternative hair dyes, caution is needed as the risk of developing an allergy to other hair dye ingredients, especially PTD, is high. PMID:25302475

    Analytical expressions for the signal enhancement in solid-state PHIP NMR spectroscopy mediated by homonuclear dipolar interactions and single pulse or spin-echo excitation are developed and simulated numerically. It is shown that an efficient enhancement of the proton NMR signal in solid-state NMR studies of chemisorbed hydrogen on surfaces is possible. Employing typical reaction efficacy, enhancement-factors of ca. 30-40 can be expected both under ALTADENA and under PASADENA conditions. This result has important consequences for the practical application of the method, since it potentially allows the design of an in-situ flow setup, where the para-hydrogen is adsorbed and desorbed from catalyst surfaces inside the NMR magnet.

  2. Construction of a Para-Ortho Hydrogen Test Cryostat

    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.

  3. a New Equation of State for Solid para-HYDROGEN

    NASA Astrophysics Data System (ADS)

    Wang, Lecheng; Le Roy, Robert J.; Roy, Pierre-Nicholas

    2015-06-01

    Solid para-H_2 is a popular accommodating host for impurity spectroscopy due to its unique softness and the spherical symmetry of para-H_2 in its J}=0 rotational level. To simulate the properties of impurity-doped solid para-H_2, a reliable model for the `soft' pure solid para-H_2 at different pressures is highly desirable. While a couple of experimental and theoretical studies aimed at elucidating the equation of state (EOS) of solid para-H_2 have been reported, the calculated EOS was shown to be heavily dependent on the potential energy surface (PES) between two para-H_2 that was used in the simulations. The current study also demonstrates that different choices of the parameters governing the Quantum Monte Carlo simulation could produce different EOS curves. To obtain a reliable model for pure solid para-H_2, we used a new 1-D para-H_2 PES reported by Faruk et al. that was obtained by averaging over Hinde's highly accurate 6-D H_2--H_2 PES. The EOS of pure solid para-H_2 was calculated using the PIMC algorithm with periodic boundary conditions (PBC). To precisely determine the equilibrium density of solid para-H_2, both the value of the PIMC time step (τ) and the number of particles in the PBC cell were extrapolated to convergence. The resulting EOS agreed well with experimental observations, and the hcp structured solid para-H_2 was found to be more stable than the fcc one at 4.2K, in agreement with experiment. The vibrational frequency shift of para-H_2 as a function of the density of the pure solid was also calculated, and the value of the shift at the equilibrium density is found to agree well with experiment.

    The ParaDiS code is developed to study bulk systems with periodic boundary conditions. When we try to perform discrete dislocation dynamics simulations for finite systems such as thin films or cylinders, the ParaDiS code must be extended. First, dislocations need to be contained inside the finite simulation box; Second, dislocations inside the finite box experience image stresses due to the free surfaces. We have developed in-house FEM subroutines to couple with the ParaDiS code to deal with free surface related issues in the dislocation dynamics simulations. This primer explains how the coupled code was developed, the main changes from the ParaDiS code, and the functions of the new FEM subroutines.

    1983-01-01

    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.

  6. Para hydrogen equilibration in the atmospheres of the outer planets

    1986-01-01

    The thermodynamic behavior of the atmospheres of the Jovian planets is strongly dependent on the extent to which local thermal equilibration of the ortho and para states of molecular hydrogen is achieved. Voyager IRIS data from Jupiter imply substantial departures of the para hydrogen fraction from equilibrium in the upper troposphere at low latitudes, but with values approaching equilibrium at higher latitudes. Data from Saturn are less sensitive to the orth-para ratio, but suggest para hydrogen fractions near the equilibrium value. Above approximately the 200 K temperature level, para hydrogen conversion can enhance the efficiency of convection, resulting in a substantial increase in overturning times on all of the outer planets. Currently available data cannot definitively establish the ortho-para ratios in the atmospheres of Uranus and Neptune, but suggest values closer to local equilibrium than to the 3.1 normal ratio. Modeling of sub-millimeter wavelength measurements of these planets suggest thermal structures with frozen equilibrium lapse rates in their convective regions.

    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.

    The advent of large cosmological sky surveys - ushering in the era of precision cosmology - has been accompanied by ever larger cosmological simulations. The analysis of these simulations, which currently encompass tens of billions of particles and up to a trillion particles in the near future, is often as daunting as carrying out the simulations in the first place.

    The advent of large cosmological sky surveys—ushering in the era of precision cosmology—has been accompanied by ever larger cosmological simulations. The analysis of these simulations, which currently encompass tens of billions of particles and up to a trillion particles in the near future, is often as daunting as carrying out the simulations in the first place. Therefore, the development of very efficient analysis tools combining qualitative and quantitative capabilities is a matter of some urgency. In this paper, we introduce new analysis features implemented within ParaView, a fully parallel, open-source visualization toolkit, to analyze large N-body simulations. A major aspect of ParaView is that it can live and operate on the same machines and utilize the same parallel power as the simulation codes themselves.

    El proyecto de instrumentación de mayor importancia que ha tenido el Instituto de Astrofisica de Canarias en los últimos afios ha sido el diseflo y construcción del te1escopio IAC8O. Este requería del esfuerzo con junto en mec´nica, óptica y electrónica, lo que facilitó la estructuración y el crecimiento de los respectivos grupos de trabajo, que posteriormente se integraron en departamentos En su origen (1977), el telescopio IAC80 fue concebido como un sistema clásico tipo Cassegrain, con una razón focal F/i 1.3 para el sistema Casse grain y una razón focal F/20 para el sistema Coudé. Posteriormente, aunque se mantuvo la filosofia de que el sistema básico fuera el F/11.3, se consideró conveniente el diseño de secundarios para razones focales F/16 y F/32, y se eliminó el de F/20. Sin embargo, dada la importancia relativa que un foco estrictamente fotográfico tiene en un telescopio moderno, diseñado básicamente para fotometría fotoeléctrica y con un campo util mínimamente de 40 minutos de arco, se decídió Ilevar a cabo el diseño de un secundario F/8 con un sistema corrector de campo, pero que estuviera formado únicamente por lentes con superficies esféricas para que asl su construcción fuera posible en España ó en México. La creciente utilización de detectores bidimensionales para fines de investigación astron6mica y la viabilidad de que en un futuro cercano éstos tengan un área sensible cada vez mayor, hicieron atractiva la idea de tener diseñado un sistema corrector de campo para el foco primario (F/3), con un campo útil mínimo de un grado, y también con la limitante de que sus componentes tuvieron sólamente supérficies esféricas. Ambos diseños de los sis-temas correctores de campo se llevaron a cabo, en gran medida, como parte de un proyecto de colaboración e intercambio en el área de diseño y evaluación de sistemas ópticos.

    The design and operation of a compact converter to produce a constant flow of para-hydrogen from normal hydrogen is described. The converter features a paramagnetic compound (nickel sulfate) that catalyses the conversion of ortho- to para-hydrogen at temperatures of 14-21 K. The converter has been tested by measuring rotationally resolved photoelectron spectra in the para-hydrogen produced. The percentage of the para-hydrogen species in the converted gas was determined to be >97%.

    Pseudomonas putida DLL-E4 can efficiently degrade para-nitrophenol and its intermediate metabolite hydroquinone. The regulation of para-nitrophenol degradation was studied, and PNP induced a global change in the transcriptome of P. putida DLL-E4. When grown on PNP, the wild-type strain exhibited significant downregulation of 2912 genes and upregulation of 845 genes, whereas 2927 genes were downregulated and 891 genes upregulated in a pnpR-deleted strain. Genes related to two non-coding RNAs (ins1 and ins2), para-nitrophenol metabolism, the tricarboxylic acid cycle, the outer membrane porin OprB, glucose dehydrogenase Gcd, and carbon catabolite repression were significantly upregulated when cells were grown on para-nitrophenol plus glucose. pnpA, pnpR, pnpC1C2DECX1X2, and pnpR1 are key genes in para-nitrophenol degradation, whereas pnpAb and pnpC1bC2bDbEbCbX1bX2b have lost the ability to degrade para-nitrophenol. Multiple components including transcriptional regulators and other unknown factors regulate para-nitrophenol degradation, and the transcriptional regulation of para-nitrophenol degradation is complex. Glucose utilization was enhanced at early stages of para-nitrophenol supplementation. However, it was inhibited after the total consumption of para-nitrophenol. The addition of glucose led to a significant enhancement in para-nitrophenol degradation and up-regulation in the expression of genes involved in para-nitrophenol degradation and carbon catabolite repression (CCR). It seemed that para-nitrophenol degradation can be regulated by CCR, and relief of CCR might contribute to enhanced para-nitrophenol degradation. In brief, the regulation of para-nitrophenol degradation seems to be controlled by multiple factors and requires further study. PMID:27191401

    La contaminacion ambiental por campos electromagneticos ha resultado ser en estos ultimos anos uno de los problemas mas acuciantes del panorama tecnologico y de salud publica. En el primero de los casos porque las inversiones realizadas son enormes y en el segundo porque cada vez es mayor el numero de articulos, "technical reports" e informes medicos que afirman la existencia de una cierta causalidad, aunque sea debil, entre los campos electromagneticos y ciertos cuadros sintomatologicos. En nuestro caso, hemos dedicado bastantes esfuerzos a investigar el llamado "sindrome de radiofrecuencia / microondas", denominado asi en la literatura cientifica por presentarse en operarios de estaciones de radar y en trabajadores de potentes emisoras de radio y television. En esta memoria presentamos un resumen del trabajo realizado durante los ultimos anos en la medida de la contaminacion electromagnetica ambiental asociado a las comunicaciones inalambricas. En ella se recogen los fundamentos fisicos y propiedades de las ondas electromagneticas, la tecnologia empleada en los sistemas de telefonia celular y los antecedentes relativos a la investigacion de la interaccion de las ondas electromagneticas con organismos vivos. Se desarrolla un procedimiento de medida que ha conducido a la elaboracion de los primeros "mapas de radiofrecuencia" similares, en el aspecto descriptivo, a los mapas de ruido desarrollados en el area de la contaminacion acustica. Por ultimo, se analiza la respuesta subjetiva de los residentes, personas que viven en el entorno de cobertura de las estaciones base de telefonia movil y que se ven sometidos a determinados niveles de radiacion electromagnetica, con el fin de situar este fenomeno al nivel que le corresponde en el ambito de la respuesta subjetiva ciudadana.

    Para rubber seed was macerated in petroleum ether and n-hexane, individually, for 30 min. The extraction was additionally performed by reflux and soxhlet for 6 h with the same solvent and proportion. Soxhlet extraction by petroleum ether afforded the greatest extractive yield (22.90 ± 0.92%). Although antioxidant activity by means of 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay was insignificantly differed in soxhleted (8.90 ± 1.15%) and refluxed (9.02 ± 0.71%) by n-hexane, soxhlet extraction by n-hexane was significantly (p < 0.05) potent scavenged 2,2'-azino-bis(3-ethylbenzothaiazoline)-6-sulfonic acid) or ABTS radical with trolox equivalent antioxidant capacity (TEAC) of 66.54 ± 6.88 mg/100 g oil. This extract was non cytotoxic towards normal human fibroblast cells. In addition, oleic acid and palmitic acid were determined at a greater content than in the seed of para rubber cultivated in Malaysia, although linoleic and stearic acid contents were not differed. This bright yellow extract was further evaluated on other physicochemical characters. The determined specific gravity, refractive index, iodine value, peroxide value and saponification value were in the range of commercialized vegetable oils used as cosmetic raw material. Therefore, Para rubber seed oil is highlighted as the promising ecological ingredient appraisal for cosmetics. Transforming of the seed that is by-product of the important industrial crop of Thailand into cosmetics is encouraged accordingly. PMID:24976614

    La telemedicina es una tendencia creciente en la prestación de los servicios médicos. Aunque la eficacia de esta práctica no ha estado bien establecida, es probable que los países en desarrollo compartirán este nuevo paradigma con los desarrollados. Los defensores de la telemedicina en América Latina sostienen que será una herramienta útil para reducir las disparidades y mejorar la accesibilidad de atención de salud. Aunque América Latina quizá se convierta en un lugar para la investigación e investigación de estos procedimientos, no está claro cómo la telemedicina podría contribuir a mejorar la accesibilidad para las poblaciones desfavorecidas, o coexistir con sistemas de atención de salud públicos crónicamente enfermos. Telemedicine is a growing trend in the provision of medical services. Although the effectiveness of this practice has not been well established, it is likely that developing countries will share this new paradigm with developed ones. Supporters of telemedicine in Latin America maintain that it will be a useful tool for reducing disparities and improving health care accessibility. Although Latin America might become a place for research and investigation of these procedures, it is not clear how telemedicine could contribute to improving accessibility for disadvantaged populations, or coexist with chronically ill-funded public healthcare systems.

    The small serine resolvase ParA from bacterial plasmids RK2 and RP4 catalyzes the recombination of two identical 133 bp recombination sites known as MRS. Previously, we reported that ParA is active in the fission yeast Schizosaccharomyces pombe. In this work, the parA recombinase gene was placed under the control of the Arabidopsis OXS3 promoter and introduced into Arabidopsis lines harboring a chromosomally integrated MRS-flanked target. The ParA recombinase excised the MRS-flanked DNA and the excision event was detected in subsequent generations in the absence of ParA, indicating germinal transmission of the excision event. The precise site-specific deletion by the ParA recombination system in planta demonstrates that the ParA recombinase can be used to remove transgenic DNA, such as selectable markers or other introduced transgenes that are no longer desired in the final product.

    The ortho-para chemistry of ammonia in the cold interstellar medium is investigated using a gas-phase chemical network. Branching ratios for the primary reaction chain involved in the formation and destruction of ortho- and para-NH{sub 3} were derived using angular momentum rules based on the conservation of the nuclear spin. We show that the 'anomalous' ortho-to-para ratio of ammonia ({approx}0.7) observed in various interstellar regions is in fact consistent with nuclear spin selection rules in a para-enriched H{sub 2} gas. This ratio is found to be independent of temperature in the range 5-30 K. We also predict an ortho-to-para ratio of {approx}2.3 for NH{sub 2}. We conclude that a low ortho-to-para ratio of H{sub 2} naturally drives the ortho-to-para ratios of nitrogen hydrides below the statistical values.

    Purpose Treatment of patients with para-aortic lymph node metastasis from colorectal cancer is controversial. The goal of this study was to investigate the technical feasibility of laparoscopic intrarenal para-aortic lymph node dissection in patients with colorectal cancer and clinically suspected para-aortic lymph node dissection. Methods The inclusion criteria for the laparoscopic approach were patients with infrarenal para-aortic lymph node metastasis from colorectal cancer. Patients who had any other distant metastatic lesion or metachronous para-aortic lymph node metastasis were excluded from this study. Perioperative outcomes and survival outcomes were analyzed. Results Between November 2004 and October 2013, 40 patients underwent laparoscopic para-aortic lymph node dissection. The mean operating time was 192.3 ± 68.8 minutes (range, 100-400 minutes) and the mean estimated blood loss was 65.6 ± 52.6 mL (range, 20-210 mL). No patient required open conversion. The postoperative complication rate was 15.0%. Sixteen patients (40.0%) had pathologically positive lymph nodes. In patients with metastatic para-aortic lymph nodes, the 3-year overall survival rate and disease-free survival rate were 65.7% and 40.2%, respectively. Conclusion The results of our study suggest that a laparoscopic approach for patients with colorectal cancer with metastatic para-aortic lymph nodes can be a reasonable option for selected patients.

    This study analyzed the forensic features of homicides in North-West Greece (Epirus) from 1998 to 2013, a borderland area between Greece and Albania. Although Greece is critically influenced by both the increasing flow of refugees and the current socioeconomic crisis, very little information has been published regarding the patterns of homicide in the country. Fifty-eight autopsied victims (36 males; 22 females) were investigated. The median age was 37 years old. The average annual homicide rate was 0.85 per 100,000 inhabitants and showed remarkable fluctuation, with largest increase during Greek financial downturn. Sixteen victims were not Greek citizens. The most common method of commitment was the use of firearm (40%). The main motives were economical causes (26%) and passion (14%). Four cases were categorized as matricide (7%), 3 as homicide-suicide (5%), 2 as patricide (3%) and 1 as infanticide (2%). Toxicological analysis proved negative for ethanol and other psychotropic substances in the majority of the victims (50%). There is an urgent need for public actions both in Epirus and in Greece, with the application of effective strategies against criminality. PMID:26580723

    Mobbing, or psychological harassment at the workplace, is usually defined as a situation in which a person or a group of people engage in extreme psychological violence against another person. In Spain, the number of reports for mobbing has increased extraordinarily in the last years. The reports are increasing dramatically not only before the Labour Courts, but also before the Civil Courts, with claims for damages, and before the Penal Court for offences causing physical or moral injury, etc., since at the present time this figure is not typified as an offence in the Spanish Penal Code. The high degree of complexity of this situation has given rise to frequent misuse of the term and to a number of false accusations of mobbing. A recent European Parliament Resolution on harassment at the workplace addressed the devastating consequences of false accusations. In this paper we present a case in which the "false" victim was mentally ill (paranoia) but succeed in generating an extreme dangerous environment of great harassment against the "false" assailants that were "falsely" accused of mobbing. Forensic diagnosis of the psychiatric disorder suffered by the "false" victim was essential to clarify the issue at the Penal Court. PMID:15639569

    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

    This Article focuses on an often overlooked barrier to efforts to enhance the quality of health care: the relationship crisis that currently exists between physicians and patients. This state of affairs has resulted from the divide between the medical and legal worlds. The medical arena has understandably tended to view the doctor-patient relationship as a purely medical issue, ignoring the law's impact in generating and sustaining problematic relationship patterns. The legal world has yet to fully recognize this state of affairs, and the law's role in its evolution and persistence. We offer a relational approach to health-care law as a means of bridging the divide between the two disciplines. In the malpractice context, this would entail adopting a no-fault compensation scheme, which is committed to strengthening collaborative doctor-patient relations, enhancing patient safety and systemic learning, while providing adequate compensation.

    Complexity and contradictoriness of the triplet life quality-health-risk gain particular acuity owing to the extensive and intensive nature of radiation and non-radiation risks in the modern technological society. Improvement of life standards issue new risks. Unavoidability of existing risks, emergence of new ones, and necessity of qualitative, first of all energetic, life maintenance come into conflict with the principles of ecological stability. The concept of life quality is in many respects irrational and in the future will largely hinge on traditions, ideological and religious maxims. PMID:8012301

    Nyagrŏdha the Banyan tree (Ficus bengalensis Linn.) is a sacred medicinal plant since Vedic times. The English name Banyan is given by the Britishers to this tree because under the tree Banias i.e., the Hindu merchants used to assemble for business. The triad Ganges, the Himalayas and the Banyan tree are symbolise the images of India, hence it is considered as National Tree. Ficus means fig and bengalensis means belonging to or is of Bengal. To the most of Indians it is Sacred and symbolizes all three Gods of Hindus. The bark represents Lord Visnu, Brahma the roots and Siva the branches. Since Vedic times its small branches are used in Yajña (a sacrificial rite) and known for its giant structure. Alexander the Great is said to have camped under a banyan tree, which was big enough to shelter his whole army of 7,000 men. As per Vĕda it checks the environmental pollution and one of the source of Lăksă (Lac). Its medicinal importance is well documented in Ayurvĕda literature. However, more research needs for understanding the medicinal properties of this symbolic tree. PMID:19580111

    A man of 23 years, diabetic of type 1, shows a functional handicap of the right upper limb following a convulsion in the context of hypoglycemia. On arrival of the "S.A.M.U.", the physician diagnoses an anterior shoulder dislocation that he decides to reduce on the spot after analgesic treatment. The X-ray examination at the emergency shows a reduction of the dislocation as well as a fracture of the greater tuberosity. Has the fracture followed the convulsion or the reduction movement ? The absence of an X-ray examination before the reduction movement presents a forensic medical problem. Certain criteria mentioned in several studies would allow the reduction without X-ray before. However, these studies remain controversial. PMID:26749634

    Murder is perpetrated, suicide is committed and lethal accidents happen everywhere, even in the heart of the French country. In the 19th century, law often appealed to the lights of experts. During criminal investigation, improvisation and men's adaptation were important, although forensic autopsy was official and necessary. Sometimes the magistrates appealed to young people, not used to that kind of reports, who could only remind some bits of the forensic courses they had followed when they were students. As for the specialists, the circumstances often led them to examine--as Baudelaire would say--the "decaying carcass," in a dark and suffocating ruined house, on the kitchen table, and with a simple scapel.

Within the context of South African criminal law, the impact of psychopathy on criminal liability has been addressed in numerous decisions with varying outcomes all indicative of the reality that psychopathy will at most serve as a factor in mitigation of sentence, but will not exonerate an accused of criminal responsibility. In this contribution, the author reflects on the diagnostic entities of psychopathy and antisocial personality disorder against the backdrop of South African criminal law cases in terms of which either of these entities were raised in support of mitigation of sentence and/or as extenuating circumstances.

    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.

    This historical vignette explores the considerations of the Nobel Prize Committee for Physiology or Medicine by vetting the Nobel Prize chances of Dr Gustaf Zander (1835-1920). His way to stardom started 150 years ago when he began mechanizing the passive and active movements that physical therapists manually used to treat diseases. A glance at his machines shows that they parallel surprisingly well what can be found in modern fitness studios. By combining files from the Nobel Prize Archive and sources from the first physical therapists, this vignette pieces together why Zander was considered one of the best candidates for the Nobel Prize in 1916. By providing this glimpse of history, questions about the origin of physical therapy concepts and the profession of the physical therapist are raised. PMID:25655882

    The application of the histochemical stain of sodium rhodizonate to the entrance wound for the detection of the lead (Pb) residues coming from the gunshot may be affected by false positive cases due to the contamination of the environmental Pb. The aim of the Authors is to histochemically search the Pb of GSR in a region which should be more protected by the contamination: the intracorporeal channel. Two hundreds and eighteen serial histological specimens of the intracorporeal channels coming from 25 subjects (dead due to gunshots and being autopsied at the Section of Legal Medicine of the Milan University, in the years 2013-2014) were stained with the sodium rhodizonate and sodium rhodizonate in acid environment (HCl 5%), and then observed by the microscope. The sodium rhodizonate showed a positivity for the Pb residues in the intracorporeal channel, with the detection of the particles within the first 2 cm beyond the entrance wound in 6 cases over the total number of 25 (24%). Victims were characterized by common features: short-barreled weapon; contact shots or short-distance shots; involvement of regions that were not covered by clothing; preservation of the microscopic structure of organs interested by the intracorporeal channel. The searching of GSR in the intracorporeal channel, even in conditions securing a high sensitivity, could represent an important test for the discrimination between an environmental contamination of Pb and the presence of Pb residues by GSR: once confirmed the presence of GSR in the intracorporeal channel by the histochemical analysis, the diagnostic process should require the application of the SEM-EDX for the confirmation of the results. Although not yet studied, this combination could be applied to cadavers exposed to the environment, with advanced post-mortal phenomena permitting at least the suspects of the existence of gunshot wounds at the macroscopic autopsy evaluation. Indeed, in some cases, the putrefaction is so advanced that no suspect of gunshot injuries could be derived from the soft tissue. PMID:26320004

    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.

    Considering 11 cases of psychiatric expert reports in criminal cases, the author's aim is to describe the criminological aspects of offences by notaries, mainly swindle and breach of trust. It appears that can be found in this professional category, personality types already described for "closely acquainted", or business crooks, as well as four obviously pathological cases, coming within the provisions of article 64 of the criminal code. Beyond the fact that there is a specific pre-criminal situation: dealing with contracts, assets, funds etc... the authors notices in several cases a discrepancy between the weak and immature personality of some notaries and the importance of the office with which they are entrusted. Thus the requirement of ability and sufficient professional qualification was not always met. The authors would be interested in further similar observations, to confirm or infirm their conclusions.

    The authors review the doctrine of criminal law and the jurisdiction of the Supreme Court in search of a starting point for the legal protection of human life and health. In cases of medical errors in obstetrics concerning a fetus, an act of a perpetrator can be classified as manslaughter or exposure to direct danger of loss of life or great bodily injury depending on whether the fetus is recognized as "a human being". The authors criticize the doctrinal criteria of the beginning of legal protection: spatial, physiological, obstetric, and developmental, pointing to the possibilities of decriminalization of medical errors of omission. A solution to this situation is the presented evolution of the jurisdiction of the Supreme Court. It moves towards establishing the beginning of legal and criminal protection of life and health at the "moment of emergence of objective grounds to necessitate delivery". PMID:22715678

    The psychiatrist's assessment of criminal responsibility of an accused in court for an act of crime has always been a matter of great difficulty. In 1997, clause 300a was incorporated into the Penal Code of Israel, thereby permitting a more lenient punishment for murder than mandatory life imprisonment. The clause includes the definition of what is meant by "severe mental disorder" and "significantly restricted capacity" by the defendant to understand the criminal nature of his or her act and to refrain from committing it. Usage of the concepts "disorder" and "significantly restricted capacity" in addressing the issue of diminished responsibility of the mentally ill is new to the Israeli legal code. The emergence and evolvement of the above concepts are presented through a historical review of the Israeli encoded law concerning mental illness, analyzed from a psychiatric perspective.

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.

    The main aim of this study was to determine the causes and epidemiological aspects of unnatural deaths in the elderly. Data were collected on 4405 male and female victims of unnatural deaths aged 50 years or more from the total number of 21,235 autopsies performed in King George's Medical University, Lucknow, India over a 5-year period, from 2008 to 2012. There were 3165 male victims and 1240 female victims. Unnatural deaths were higher in rural (64%) than in urban (37%) areas. Accidental deaths were the most common manner of unnatural deaths (59%), followed by suicidal deaths (34%) and homicidal deaths (7%). Traumas were the most common cause of unnatural death (77.3%), followed by undetermined causes (16.6%) and toxicological causes (6.1%). The most common causes of traumatic deaths were blunt head injuries (34%) followed by stab in the chest (6%), burn (16%), blunt injuries in abdomen and chest (10%), firearm injuries in the head and trunk (9%), strangulation (3%), stab in the abdomen (4%), smothering (4%), cut throat (3%), throttling (1%) and hanging (10%). Carbamate poisoning was the most common cause of toxicological deaths (44%) followed by organophosphorous poisoning (33%), ethyl alcohol poisoning (12%), barbiturate poisoning (3%) and zinc phosphide poisoning (8%).

    Examination of cloths is a permanent sphere in the practice of forensic-medical expert and an indispensable expertise stage providing for decision-making on the key issues set before the expert. Although, the examination of cloth in forensic-medical expertise has been productive, research in this field slowed down during the recent decades; definition of new sets of evident informative signs has been also suspended. The methodological potentialities of examination of cloths items were demonstrated by examples of aviation incidents because such incidents reflect the principle variations of impacts, i.e. blow, explosion, fire, compression and chemical factors etc., which are subject to examination in the forensic-medical practice. Identification of mechanism causing damage and other signs on cloths helps a lot the forensic-medical expert in solving quite a number of issues related with circumstances of an incident and with a nature of an impact encountered by a person.

    Twenty-six of 95 adults treated for tuberculous spondylitis, between 1982 and 1993, underwent surgery. Twenty-one exhibited neurological deficits: radicular deficits: 4, and progressive spinal cord syndromes: 17 (incomplete, 13, complete, of acute onset: 4). Vertebral body compression fracture was the most prominent finding. Indications for surgery were neurologic: 11, mechanical: 1, etiologic: 1, and mixed: 13. Twelve patients had vertebrectomies, 3 laminotomies and 11 laminectomies. The average follow-up was 23 months. The neurological recovery was complete in 16 cases, partial in 4 cases and unchanged in one case. Bony consolidation occurred after 3-5 months. The medicosurgical treatment produced a very high cure rate, so rapidly, that it became the treatment of choice in our setting. Moreover, that allows to specify the diagnosis. Anterior decompression and fusion is recommended in the cervical and lumbar spine. In the thoracic segment, significant kyphosis is infrequent, so that surgical correction is rarely necessary. Laminotomy may occasionally be indicated for posterior decompression for abscess. Laminectomy is now preferred for uncommon cases of thoracolumbar posterior compression by tuberculous arachnoiditis or associated posterior vertebral tuberculosis. Indications for open biopsy are discussed. PMID:7874618

    Clear data on the epidemiology of medical malpractice are missing, at least for Germany. Especially data on the frequency of malpractice claims in penal and civil law are not available. However, from epidemiological and healthcare research some data on the frequency of adverse events (AE), preventable adverse events (PAE) and negligent adverse events (NAE) are available. According to a review of the German Alliance of Patient Safety adverse events can be expected in 5-10%, preventable adverse events in 2-4%, negligent adverse events in about 1% and lethal outcome in about 0.1% of hospitalized patients. However, these data are not compatible with figures from civil and penal law and there seems to be a great "litigation gap". Data on malpractice cases are available from the files of the arbitration committees on medical malpractice, files of liability insurance companies and files of the institutes of forensic medicine. However, these files are not complete and data sources may have some interferences. The arbitration committees are, however, mainly dealing with living patients. Lethal cases are a special subgroup and the best available data source are the files of the institutes of forensic medicine. This subgroup is of special importance since death is the most severe outcome of medical malpractice and the reproach to have caused the death of a patient by medical negligence is the most severe malpractice claim. From a retrospective multicentre study on autopsies performed in cases of medical malpractice claims (altogether 101.358 autopsies, 4450 due to medical malpractice claims) the most important data will be presented (disciplines concerned, cause of accusation, classification of accusation, causes of preliminary proceedings, occupational group and number of approved medical malpractice, outcome of medical malpractice proceedings). However, these data are not only of a descriptive value but have utmost importance also for risk analysis and to increase patient safety. A thorough evaluation of serious incidences, although less sophisticated than a root cause analysis, produces far more information than the usual hospital reporting system. Identification and evaluation of errors as well as reporting of errors may also contribute to the prevention of errors which is among other medical disciplines also a task of forensic medicine.

    The incidence of rheumatism and rheumatic valvulopathy in Sicily is assessed and the sites most commonly involved in the first and second attacks described. The medical aspects of te question are examined from several points of view: prophylaxis of sites, medical treatment personal and ambient hygiene, gradual defectiveness of the pump, associated diseases, etc. The concept of invalidity is viewed in terms of direct and associated anatomical damage and frank and potential invalidity (absolute or relative), the weight or assistance attributable to the family and the incidence of the local social environment in the question of finding work, etc. The basic criteria for surgery are noted. Care must be taken to preserve the few remaining structures. Mortality is still high and the incidence of heart disease is higher among rheumatic Sicilian children. Not enough is known about overcrowding, the schools attended by the poor, and the higher incidence in low-income classes. Failure to affront some of these features, determined as much by action (or its postponement) by government as by income, results in meaningless medicine, divorced from social reform and true the scientific spirit, a cover for special interests and a demonstration of profit factors wherein the commercialising relationship is increasingly evident.

    2015-09-01

    The 2010 report of the United Kingdom Science and Technology Committee of the House of Commons and the 2015 report of the Australian National Health and Medical Research Council have overtaken in significance the uncritical Swiss report of 2012 and have gone a long way to changing the environment of tolerance toward proselytising claims of efficacy in respect of homeopathy. The inquiry being undertaken in the United States by the Food and Drug Administration during 2015 may accelerate this trend. An outcome of the reports and inquiries has been a series of decisions from advertising regulators and by courts rejecting medically unjustifiable claims in respect of the efficacy of homeopathy. Class actions have also been initiated in North America against manufacturers of homeopathic products. The changing legal and regulatory environment is generating an increasingly scientifically marginalised existence for homeopathy. That new environment is starting to provide effective inhibition of assertions on behalf of homeopathy and other health modalities whose claims to therapeutic efficacy cannot be justified by reference to the principles of evidence-based health care. This has the potential to reduce the financial support that is provided by insurers and governments toward homeopathy and to result in serious liability exposure for practitioners, manufacturers and those who purvey homeopathic products, potentially including pharmacists. In addition, it may give a fillip to a form of regulation of homeopaths if law reform to regulate unregistered health practitioners gathers momentum, as is taking place in Australia. PMID:26554194

    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.

    RVA is a plugin developed for the 64-bit Windows version of the ParaView 3.14 visualization package. RVA is designed to provide support in the visualization and analysis of complex reservoirs being managed using multi-fluid EOR techniques. RVA, for Reservoir Visualization and Analysis, was developed at the University of Illinois at Urbana-Champaign, with contributions from the Illinois State Geological Survey, Department of Computer Science and National Center for Supercomputing Applications. RVA was designed to utilize and enhance the state-of-the-art visualization capabilities within ParaView, readily allowing joint visualization of geologic framework and reservoir fluid simulation model results. Particular emphasis was placed on enabling visualization and analysis of simulation results highlighting multiple fluid phases, multiple properties for each fluid phase (including flow lines), multiple geologic models and multiple time steps. Additional advanced functionality was provided through the development of custom code to implement data mining capabilities. The built-in functionality of ParaView provides the capacity to process and visualize data sets ranging from small models on local desktop systems to extremely large models created and stored on remote supercomputers. The RVA plugin that we developed and the associated User Manual provide improved functionality through new software tools, and instruction in the use of ParaView-RVA, targeted to petroleum engineers and geologists in industry and research. The RVA web site (http://rva.cs.illinois.edu) provides an overview of functions, and the development web site (https://github.com/shaffer1/RVA) provides ready access to the source code, compiled binaries, user manual, and a suite of demonstration data sets. Key functionality has been included to support a range of reservoirs visualization and analysis needs, including: sophisticated connectivity analysis, cross sections through simulation results between

    We study single dibenzoterrylene (DBT) molecules embedded in 1,4-dichlorobenzene (para-dichlorobenzene, pDCB) at 1.2 K. Due to the relatively low melting point of pDCB (53 °C), this host-guest system can be easily prepared from the molten phase. Narrow linewidths, stable molecular lines and high saturation count rates of single DBT molecules were observed. For this reason, we consider this host-guest system a promising candidate for the study of interactions of single molecules with other small objects such as waveguides or nanoparticles.

RVA is designed to provide support in the visualization and analysis of complex reservoirs being managed using multi-fluid EOR techniques. RVA, for Reservoir Visualization and Analysis, was developed at the University of Illinois at Urbana-Champaign, with contributions from the Illinois State Geological Survey, Department of Computer Science and National Center for Supercomputing Applications. RVA was designed to utilize andmore » enhance the state-of-the-art visualization capabilities within ParaView, readily allowing joint visualization of geologic framework and reservoir fluid simulation model results. Particular emphasis was placed on enabling visualization and analysis of simulation results highlighting multiple fluid phases, multiple properties for each fluid phase (including flow lines), multiple geologic models and multiple time steps. Additional advanced functionality was provided through the development of custom code to implement data mining capabilities. The built-in functionality of ParaView provides the capacity to process and visualize data sets ranging from small models on local desktop systems to extremely large models created and stored on remote supercomputers. The RVA plugin that we developed and the associated User Manual provide improved functionality through new software tools, and instruction in the use of ParaView-RVA, targeted to petroleum engineers and geologists in industry and research. The RVA web site (http://rva.cs.illinois.edu) provides an overview of functions, and the development web site (https://github.com/shaffer1/RVA) provides ready access to the source code, compiled binaries, user manual, and a suite of demonstration data sets. Key functionality has been included to support a range of reservoirs visualization and analysis needs, including: sophisticated connectivity analysis, cross sections through simulation results

    The Amaryllidaceae alkaloids are a family of amino acid derived alkaloids with many biological activities; examples include haemanthamine, haemanthidine, galanthamine, lycorine, and maritidine. Central to the biosynthesis of the majority of these alkaloids is a C-C phenol-coupling reaction that can have para-para', para-ortho', or ortho-para' regiospecificity. Through comparative transcriptomics of Narcissus sp. aff. pseudonarcissus, Galanthus sp., and Galanthus elwesii we have identified a para-para' C-C phenol coupling cytochrome P450, CYP96T1, capable of forming the products (10bR,4aS)-noroxomaritidine and (10bS,4aR)-noroxomaritidine from 4′-O-methylnorbelladine. CYP96T1 was also shown to catalyzed formation of the para-ortho' phenol coupled product, N-demethylnarwedine, as less than 1% of the total product. CYP96T1 co-expresses with the previously characterized norbelladine 4′-O-methyltransferase. The discovery of CYP96T1 is of special interest because it catalyzes the first major branch in Amaryllidaceae alkaloid biosynthesis. CYP96T1 is also the first phenol-coupling enzyme characterized from a monocot. PMID:26941773

    Background: Aromatic compounds are known as a group of highly persistent environmental pollutants. Halomonas sp. TBZ3 was isolated from the highly salty Urmia Lake of Iran. In this study, characterization of a new Halomonas isolate called Halomonas sp. TBZ3 and its employment for biodegradation of para-amino acetanilide (PAA), as an aromatic environmental pollutant, is described. Objectives: This study aimed to characterize the TBZ3 isolate and to elucidate its ability as a biodegradative agent that decomposes PAA. Materials and Methods: Primarily, DNA-DNA hybridization between TBZ3, Halomonas denitrificans DSM18045T and Halomonas saccharevitans LMG 23976T was carried out. Para-amino acetanilide biodegradation was assessed using spectrophotometry and confirmed by gas chromatography-mass spectroscopy (GC-MS). Parameters effective on biodegradation of PAA were optimized by the Response Surface Methodology (RSM). Results: The DNA-DNA hybridization experiments between isolate TBZ3, H. denitrificans and H. saccharevitans revealed relatedness levels of 57% and 65%, respectively. According to GC-MS results, TBZ3 degrades PAA to benzene, hexyl butanoate, 3-methyl-1-heptanol and hexyl hexanoate. Temperature 32.92°C, pH 6.76, and salinity 14% are the optimum conditions for biodegradation with a confidence level of 95% (at level α = 0.05). Conclusions: According to our results, Halomonas sp. TBZ3 could be considered as a biological agent for bioremediation of PAA and possibly other similar aromatic compounds. PMID:26495103

  20. Ortho-para mixing hyperfine interaction in the H2O+ ion and nuclear spin equilibration.

    The ortho to para conversion of water ion, H2O(+), due to the interaction between the magnetic moments of the unpaired electron and protons has been theoretically studied to calculate the spontaneous emission lifetime between the ortho- and para-levels. The electron spin-nuclear spin interaction term, Tab(SaΔIb + SbΔIa) mixes ortho (I = 1) and para (I = 0) levels to cause the "forbidden" ortho to para |ΔI| = 1 transition. The mixing term with Tab = 72.0 MHz is 4 orders of magnitude higher for H2O(+) than for its neutral counterpart H2O where the magnetic field interacting with proton spins is by molecular rotation rather than the free electron. The resultant 10(8) increase of ortho to para conversion rate possibly makes the effect of conversion in H2O(+) measurable in laboratories and possibly explains the anomalous ortho to para ratio recently reported by Herschel heterodyne instrument for the far-infrared (HIFI) observation. Results of our calculations show that the ortho ↔ para mixings involving near-degenerate ortho and para levels are high (∼10(-3)), but they tend to occur at high energy levels, ∼300 K. Because of the rapid spontaneous emission, such high levels are not populated in diffuse clouds unless the radiative temperature of the environment is very high. The low-lying 101 (para) and 111 (ortho) levels of H2O(+) are mixed by ∼10(-4) making the spontaneous emission lifetime for the para 101 → ortho 000 transition 520 years and 5200 years depending on the F value of the hyperfine structure. Thus the ortho ↔ para conversion due to the unpaired electron is not likely to seriously affect thermalization of interstellar H2O(+) unless either the radiative temperature is very high or number density of the cloud is very low.

    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.

    We present a study of steady-state- and time-resolved photoluminescence of para-sexiphenyl (PSP) films on KCl grown by organic molecular beam epitaxy (OMBE). Using different OMBE growth conditions has enabled us to vary greatly the morphology of the PSP crystallites but keeping virtually untouched their chemical structure. By this comparative study we prove that the broad red-shifted emission band has a structure-related origin rather than being due to monomolecular oxidative defects. The relative intensity of the defect emission band observed in the delayed spectra was found to be drastically suppressed in the OMBE-grown films dominated by growth mounds composed of upright standing molecules as opposed to the films consisting of crystallites formed by molecules lying parallel to the substrate.

    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.

    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.

    Wave intensity analysis (WIA) was used to delineate and maximize the efficacy of a newly developed para-aortic blood pump (PABP). The intra-aortic balloon pump (IABP) was employed as the comparison benchmark. Acute porcine experiments using eight pigs, randomly divided into IABP (n = 4) and PABP (n = 4) groups, were conducted to compare the characteristics of intra- and para-aortic counterpulsation. We measured pressure and velocity with probes installed in the left anterior descending coronary artery and aorta, during and without PABP assistance. Wave intensity for aortic and left coronary waves were derived from pressure and flow measurements with synchronization correction applied. To achieve maximized support efficacy, deflation timings ranging from 25 ms ahead of to 35 ms after the R-wave were tested. Similar to those associated with IABP counterpulsation, the PABP-generated backward-traveling waves predominantly drove aortic and coronary blood flows. However, in contrast with IABP counterpulsation, the nonocclusive nature of the PABP allowed systolic unloading to be delayed into early systole, which resulted in near elimination of coronary blood steal without diminution of systolic left ventricular ejection wave intensities. WIA can elucidate subtleties among different counterpulsatile support means with high sensitivity. Total accelerating wave intensity (TAWI), which was defined as the sum of the time integration of accelerated parts of the positive and negative wave intensities, was used to quantify counterpulsation efficacy. In general, the larger the TAWI gain, the better the counter-pulsatile support efficacy. However, when PABP deflation timings were delayed to after the R-wave, the TAWI was found to be inversely correlated with coronary perfusion. In this delayed deflation timing setting, greater wave cancellation occurred, which led to decreased TAWI but increased coronary perfusion attributed to blood regurgitation reduction. PMID:22227124

The values for inulin and para-aminohippurate clearances (ml/kg/min) are similar to those for the dog. Creatinine clearance was less than inulin clearance values. Pnenolsulphothalein clearance may be a better index of glomerular rather than tubular function in the cat. PMID:4246836

    We investigated the biotransformation of the oxidative arylamine (AA) hair dye ingredients [14C]-para-aminophenol (PAP) and [14C]-para-phenylenediamine (PPD) in reconstructed human epidermis and human hepatocytes. Human epidermis quantitatively transformed PAP to its N-acetylated derivative (APAP), whereas hepatocytes transformed PAP to sulfate or glucuronic acid conjugates of APAP or PAP as well as free APAP. Epidermis and hepatocytes converted PPD to N-mono- (MAPPD) and N,N'-di-acetylated (DAPPD) derivatives. At higher concentrations of PPD (250-1000 microM), epidermis or hepatocytes produced more of the MAPPD, whereas concentrations below 250 microM and lower favoured formation of the DAPPD metabolite. When compared with epidermis, human hepatocytes had a three-fold or eight-fold greater capacity for generation of MAPPD or DAPPD, respectively. No evidence of transformation of PAP or PPD to N-hydroxylated derivatives was found in epidermis or hepatocytes. Our results suggest that (i) after dermal absorption of PAP or PPD, humans are systemically exposed to acetylated derivatives; (ii) current in vitro skin absorption studies may be inadapated for determination of human systemic exposure to AAs due to reduced or absent metabolic capacity of non-viable skin; (iii) due to qualitative differences between dermal and hepatic metabolism, oral toxicity studies may be unsuited for the hazard assessment of dermal exposure to AAs; and (iv) use of induced rodent liver S9 metabolic activation systems for in vitro genotoxicity studies may produce misleading results on the hazard of human dermal exposure to AAs. In conclusion, our data support the growing evidence that AAs are transformed in human skin and suggest that current practices of safety assessment of AAs should take these findings into account.

    The first results of female preference and chosen male mating success in a new model organism, the pentamorphic livebearing fish, Poecilia parae, are presented. Poecilia parae is a relative of the guppy, P. reticulata, and is assumed to have similar reproductive behavior. We tested the hypothesis that P. parae females, like female guppies, prefer carotenoid colored males as mates. Here we show that the time a female spent with males was significantly greater for carotenoid coloration in red and yellow melanzona, but time with these two morphs did not differ. The preferred red and yellow males mated significantly more often with their choosing females than did the non-preferred blue and parae males. The few blue melanzona and parae males that mated did so without performing courtship displays. Some females mated with all phenotypes including immaculata males during open group trials. Female P. parae clearly preferred males with carotenoid coloration, thereby corroborating the hypothesis. Alternative male mating tactics by blue melanzona, parae, and immaculata morphs and promiscuous mating by females also resembled features of reproductive behaviors exhibited by guppies.

    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.

    1995-06-01

    When microorganisms eluted from upper Hudson River sediment were cultured without any substrate except polychlorobiphenyl (PCB)-free Hudson River sediment, methane formation was the terminal step of the anaerobic food chain. In sediments containing Aroclor 1242, addition of eubacterium-inhibiting antibiotics, which should have directly inhibited fermentative bacteria and thereby should have indirectly inhibited methanogens, resulted in no dechlorination activity or methane production. However, when substrates for methanogenic bacteria were provided along with the antibiotics (to free the methanogens from dependence on eubacteria), concomitant methane production and dechlorination of PCBs were observed. The dechlorination of Aroclor 1242 was from the para positions, a pattern distinctly different from, and more limited than, the pattern observed with untreated or pasteurized inocula. Both methane production and dechlorination in cultures amended with antibiotics plus methanogenic substrates were inhibited by 2-bromoethanesulfonic acid. These results suggest that the methanogenic bacteria are among the physiological groups capable of anaerobic dechlorination of PCBs, but that the dechlorination observed with methanogenic bacteria is less extensive than the dechlorination observed with more complex anaerobic consortia. 27 refs., 5 figs., 1 tab.

    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.

    The following table constitutes an initial assessment of feature coverage across the regression test suite used for DYNA3D and ParaDyn. It documents the regression test suite at the time of production release 10.1 in September 2010. The columns of the table represent groupings of functionalities, e.g., material models. Each problem in the test suite is represented by a row in the table. All features exercised by the problem are denoted by a check mark in the corresponding column. The definition of ''feature'' has not been subdivided to its smallest unit of user input, e.g., algorithmic parameters specific to a particular type of contact surface. This represents a judgment to provide code developers and users a reasonable impression of feature coverage without expanding the width of the table by several multiples. All regression testing is run in parallel, typically with eight processors. Many are strictly regression tests acting as a check that the codes continue to produce adequately repeatable results as development unfolds, compilers change and platforms are replaced. A subset of the tests represents true verification problems that have been checked against analytical or other benchmark solutions. Users are welcomed to submit documented problems for inclusion in the test suite, especially if they are heavily exercising, and dependent upon, features that are currently underrepresented.

  3. Anise oil as para-methoxyamphetamine (PMA) precursor.

    These days, MDMA is one of the most popular drugs of abuse. Due to its illegality, MDMA and its chemical precursors are watched by governmental organizations in many countries. To avoid conflicts with legal instances, underground chemists have tried to market several new unregulated amphetamine analogues, such as 4-MTA. Para-methoxyamphetamine (PMA), on the other hand, is regulated by law but its precursors are easily obtained since they are cheap and unwatched. This article presents such a case, namely the large scale synthesis of PMA using anethole, a main constituent of anise oil, as precursor. Anethole has been converted to its phenyl acetone analogue via peracid oxidation, while PMA itself has been synthesized using this ketone as precursor in the Leuckart synthesis. The synthesis of PMA using anethole as starting product has been investigated applying GC/MS and GC-HSPME/MS techniques, hereby discovering new specific (4-methoxyphenol) and already identified synthesis impurities (4-methyl-5-(4-methoxyphenyl)pyrimidine, N-(beta-4-methoxyphenylisopropyl)-4-methoxybenzyl methyl ketimine, 1-(4-methoxyphenyl)-N-(2-(4-methoxyphenyl)-1-methylethyl-2-propanamine, 1-(4-methoxyphenyl)-N-methyl-N-(2-(4-methoxyphenyl)-1-methylethyl-2-propanamine, N-(beta-4-methoxyphenylisopropyl)-4-methoxybenzaldimine). The new impurity 4-methoxyphenol is specific for the application of a peracid oxidation method where anethole is used as precursor. PMID:12742705

    Autoxidation of para-aminophenol (PAP) has been proposed to account for the selective nephrotoxicity of this compound. However, other studies suggest that hepatic metabolites of PAP rather than the parent compound may be responsible for renal damage. These studies were designed to investigate PAP metabolism in isolated hepatocytes. We synthesized several proposed metabolites for analysis by HPLC/mass spectrometry and compared those results with HPLC/mass spectrometric analyses of metabolites found after incubating hepatocytes with PAP. Hepatocytes prepared from male Sprague-Dawley rats were incubated in Krebs-Henseleit buffer at 37 degrees C for 5 h with 2.3 mM PAP under an atmosphere of 5% CO2/95% O2. Aliquots were withdrawn at 0.1 h of incubation and then hourly through 5 h of incubation. Reactions were terminated by the addition of acetonitrile. Hepatocyte viability was unaltered with PAP present in the incubation medium. We found that hepatocytes converted PAP to two major metabolites (PAP-GSH conjugates and PAP-N-acetylcysteine conjugates) and several minor metabolites [PAP-O-glucuronide, acetaminophen (APAP), APAP-O-glucuronide, APAP-GSH conjugates, and 4-hydroxyformanilide]. Preincubating hepatoyctes with 1-aminobenzotriazole, an inhibitor of cytochromes P450, did not alter the pattern of PAP metabolism. In conclusion, we found that PAP was metabolized in hepatocytes predominantly to PAP-GSH conjugates and PAP-N-acetylcysteine conjugates in sufficient quantities to account for the nephrotoxicity of PAP.

    The conformation of dinonyl poly para phenylene ethynylenes (PPEs) with carboxylate side chains, equilibrated in solvents of different quality is studied using molecular dynamics simulations. PPEs are of interest because of their tunable electro-optical properties, chemical diversity, and functionality which are essential in wide range of applications. The polymer conformation determines the conjugation length and their assembly mode and affects electro-optical properties which are critical in their current and potential uses. The current study investigates the effect of carboxylate fraction on PPEs side chains on the conformation of chains in the dilute limit, in solvents of different quality. The dinonylmore » PPE chains are modeled atomistically, where the solvents are modeled both implicitly and explicitly. Dinonyl PPEs maintained a stretched out conformation up to a carboxylate fraction f of 0.7 in all solvents studied. The nonyl side chains are extended and oriented away from the PPE backbone in toluene and in implicit good solvent whereas in water and implicit poor solvent, the nonyl side chains are collapsed towards the PPE backbone. Thus, rotation around the aromatic ring is fast and no long range correlations are seen within the backbone.« less

    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

    Former data of our workgroup indicated that the accumulation of oxidized amino acids (meta- and ortho-tyrosine) due to oxidative stress may play an important role in the impaired insulininduced vasoactive properties of different arterial segments. There are evidences, that incorporation of these amino acids into cellular proteins leads to certain hormonal resistances, which might be restored by supplementation with the physiologic isoform, para-tyrosine. Rats in the control group were kept on a regular diet, rats in the cholesterol-fed group received high-fat diet, while the third group of rats received high-fat diet with para-tyrosine supplementation for 16 weeks. Plasma cholesterol level was significantly higher in the cholesterol-fed group, while the level of cholesterol in the cholesterol+para-tyrosine group did not differ significantly from that of the controls. Plasma level of insulin after glucose stimulation was decreased in the cholesterol-fed group, while that in the para-tyrosine supplemented group did not differ significantly from the controls. Vascular para-, meta- and ortho-tyrosine content was measured with HPLC. Elevated vascular meta-tyrosine/para-tyrosine ratio of cholesterol fed rats could be avoided by para-tyrosine supplementation. Vascular response of the thoracic aorta to insulin and liraglutide was assessed by a DMT multi-myograph. Cholesterol feeding resulted in vascular insulin-and liraglutide resistance, which was restored by para-tyrosine supplementation. Incorporation of the oxidative stress induced pathological tyrosine isoforms leads to vascular-hormone-resistances. We show that the physiological amino acid para-tyrosine is capable of restoring hypercholesterolemia-induced increased meta-tyrosine content of the vascular wall, thus attenuating functional vascular damage.

    We report a case of a ruptured para-anastomotic aortic aneurysm treated with implantation of a bifurcated stent-graft. A 72-year-old patient, who had undergone aortobifemoral bypass for aortoiliac occlusive disease 16 years ago, presented with a ruptured para-anastomotic aortic aneurysm. A bifurcated stent-graft was successfully deployed into the old bifurcated graft. This is the first report of a bifurcated stent-graft being placed through an 'end-to-side' anastomosed old aortobifemoral graft. Endovascular treatment of ruptured para-anastomotic aortic aneurysms can be accomplished successfully, avoiding open surgery which is associated with increased mortality and morbidity.

    Observations of ortho and para H2CO in two types of clouds, a warm cloud (Orion A) and two cold clouds (L183 and TMC1), are presented. The ortho to para ratio in Orion deduced from the H2(C-13)O data is about three, while that for TMC1 is about one and that for L183 is 1-2. The former value is in agreement with the value calculated from chemical models of ortho and para H2CO production. The values for the cold clouds are consistent with thermal equilibrium at a temperature slightly smaller than 10 K.

    2013-12-01

    Para-esophageal hernias are relatively rare and typically occur in elderly patients. The various presenting symptoms are non-specific and often occur in combination. These include symptoms of gastro-esophageal reflux (GERD) in 26 to 70% of cases, microcytic anemia in 17 to 47%, and respiratory symptoms in 9 to 59%. Respiratory symptoms are not completely resolved by surgical intervention. Acute complications such as gastric volvulus with incarceration or strangulation are rare (estimated incidence of 1.2% per patient per year) but gastric ischemia leading to perforation is the main cause of mortality. Only patients with symptomatic hernias should undergo surgery. Prophylactic repair to prevent acute incarceration should only be undertaken in patients younger than 75 in good condition; surgical indications must be discussed individually beyond this age. The laparoscopic approach is now generally accepted. Resection of the hernia sac is associated with a lower incidence of recurrence. Repair of the hiatus can be reinforced with prosthetic material (either synthetic or biologic), but the benefit of prosthetic repair has not been clearly shown. Results of prosthetic reinforcement vary in different studies; it has been variably associated with four times fewer recurrences or with no measurable difference. A Collis type gastroplasty may be useful to lengthen a foreshortened esophagus, but no objective criteria have been defined to support this approach. The anatomic recurrence rate can be as high as 60% at 12years. But most recurrences are asymptomatic and do not affect the quality of life index. It therefore seems more appropriate to evaluate functional results and quality of life measures rather than to gauge success by a strict evaluation of anatomic hernia reduction. PMID:24060742

  15. Efficient ortho-para conversion of H2 on interstellar grain surfaces

    NASA Astrophysics Data System (ADS)

    Bron, Emeric; Le Petit, Franck; Le Bourlot, Jacques

    2016-04-01

    Context. Fast surface conversion between ortho- and para-H2 has been observed in laboratory studies, and it has been proposed that this mechanism plays a role in the control of the ortho-para ratio in the interstellar medium. Observations of rotational lines of H2 in photo-dissociation regions (PDRs) have indeed found significantly lower ortho-para ratios than expected at equilibrium. The mechanisms controlling the balance of the ortho-para ratio in the interstellar medium thus remain incompletely understood, while this ratio can affect the thermodynamical properties of the gas (equation of state, cooling function). Aims: We aim to build an accurate model of ortho-para conversion on dust surfaces based on the most recent experimental and theoretical results, and to validate it by comparison to observations of H2 rotational lines in PDRs. Methods: We propose a statistical model of ortho-para conversion on dust grains with fluctuating dust temperatures. It is based on a master equation approach. This computation is then coupled to full PDR models and compared to PDR observations. Results: We show that the observations of rotational H2 lines indicate a high conversion efficiency on dust grains and that this high efficiency can be accounted for if taking dust temperature fluctuations into account with our statistical model of surface conversion. Simpler models that neglect the dust temperature fluctuations do not reach the high efficiency deduced from the observations. Moreover, this high efficiency induced by dust temperature fluctuations is very insensitive to the values of the model's microphysical parameters. Conclusions: Ortho-para conversion on grains is thus an efficient mechanism in most astrophysical conditions and can play a significant role in controlling the ortho-para ratio.

    Objective The objective of our study was to compare the surgical outcomes of extraperitoneal laparoscopic, transperitoneal laparoscopic, and robotic transperitoneal para-aortic lymphadenectomy in endometrial cancer staging. Methods A retrospective review was performed from January 2007 to November 2012. Three groups were compared: extraperitoneal laparoscopic para-aortic lymphadenectomy and robotic hysterectomy and pelvic lymphadenectomy (“extraperitoneal group”; N=34); laparoscopic hysterectomy and transperitoneal pelvic and para-aortic lymphadenectomy (“transperitoneal laparoscopic group”; N=108); and robotic hysterectomy and transperitoneal pelvic and para-aortic lymphadenectomy (“transperitoneal robotic group”; N=52). Fisher’s exact test and Kruskal-Wallis test were used for statistical analysis, and statistical significance was defined as P< 0.05. Results Median number of para-aortic lymph nodes obtained was higher in the extraperitoneal group than in the transperitoneal laparoscopic and robotic groups (10, 5, and 4.5 nodes, respectively; P<0.001). Among patients with BMI <35 kg/m2, the median number of para-aortic nodes harvested was higher in the extraperitoneal group than in the transperitoneal laparoscopic and robotic groups (9, 4, and 5 nodes, respectively; P<0.01). The same pattern was observed among patients with BMI ≥35 kg/m2 (10, 6, and 3 nodes, respectively) (P=0.001). There was no significant difference in median estimated blood loss between the extraperitoneal group and either the transperitoneal laparoscopic group (100 vs. 112.5 mL; P=0.06) or the transperitoneal robotic group (100 vs. 67.5 mL; P=0.23). Conclusion Extraperitoneal laparoscopic para-aortic lymphadenectomy resulted in a higher number of para-aortic lymph nodes removed than transperitoneal laparoscopic or robotic lymphadenectomy. The extraperitoneal approach should be considered for endometrial cancer staging. PMID:24361579

    Ortho-para mixing interaction due to the coupling of nuclear and electron spins was detected for the first time by millimeter-wave spectroscopy of deuterated vinyl radicals, H_2CCD and D_2CCD, of which the ground states are split by the tunneling motion of the α deuteron into two components 0^+ and 0^-, whose separations have been determined to be Δ E_0 = 1186.644(16) and 771.978(18) MHz, respectively. The observed tunneling-rotation spectra are significantly perturbed by the othro-para mixing interaction expressed by < 0^± |H'|0^mprangle = (δ aF(β)/2) S \\cdot(I_β 1-I_β 2), where I_β 1 and I_β 2 are spins of the two hydrogen nuclei in the β position and S is the electron spin, which connects rotational levels in the 0^+ and 0^- states, one being an ortho level and the other a para level. The δ aF(β) constants for H_2CCD and D_2CCD have been determined to be 68.06(53) and 10.63(94) MHz, respectively, consistent each other within the isotopic mass relation. The othro and para states are mixed by about 0.097% and 0.0123% due to this interaction. The δ aF constant for H_2CCH should be similar to that for H_2CCD because of the same probability density of the unpaired electron at the β protons, but could not be determined independently in our previous study. It is because the mixing of para- and ortho-levels of about 0.00044% is much smaller than that for H_2CCD due to the large tunneling splitting of Δ E_0=16271.8429(59) MHz. The rate constant of para to ortho (I_β = 0 → 1) conversion is predicted as 1.2× 10^5 s-1 torr-1 for H_2CCD, suggesting extremely rapid mutual conversion between ortho and para nuclear spin isomers of H_2CCD, which is more than 106 times faster compared with that in closed shell molecules such as H_2CO and H_2CCH_2.

    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 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.

    We present measurements of the H2CO ortho/para ratio toward four star-forming cores, L723, L1228, L1527, and L43, and one quiescent core, L1498. Combining these data with earlier results by Minh et al., three quiescent cores are found to have ortho/para ratios near 3, the ratio of statistical weights expected for gas-phase formation processes. In contrast, ortho/para ratios are 1.5-2.1 in five star-forming cores, suggesting thermalization at a kinetic temperature of 10 K. We attribute modification of the ortho/para ratio in the latter cores to formation and/or equilibration of H2CO on grains with sub-sequent release back into the gas phase due to the increased energy inputs from the forming star and outflow. We see accompanying enhancements in the H2CO abundance relative to H, to support this idea. The results suggest that the formaldehyde ortho/para ratio can differentiate between quiescent cores and those in which low-mass star formation has occurred.

  3. Terahertz absorption spectrum of para and ortho water vapors at different humidities at room temperature

    Terahertz time-domain spectroscopy has been used to measure the absorption of water vapor in 0.2-2.4THz range from low to high humidity at room temperature. The observed absorption lines are due to the water molecular rotations in the ground vibrational state. We find that the absorption strength of para transitions increases as humidity increases, while the absorption strength of ortho transitions increases and then decreases in intensity with increasing humidity. We explain this difference based on the nuclear spin statistics based ratio of ortho to para water monomer populations at room temperature. The preferential adsorption on the solid surfaces of para water leads to an ortho dominated vapor cloud whose monomer rotational absorption intensity decreases due to the effects of dimerization, molecular collisions, clustering, and interactions with liquid droplets at high concentrations.

    Normal hydrogen (n-H2) has 3:1 ortho/para ratio and the production of enriched para-hydrogen (p-H2) from normal hydrogen is useful for many applications including matrix isolation experiments. In this paper, we describe the design, development and fabrication of the ortho-para converter that is capable of producing enriched p-H2. The p-H2 thus produced was probed using infrared and Raman techniques. Using infrared measurement, the thickness and the purity of the p-H2 matrix were determined. The purity of p-H2 was determined to be >99%. Matrix isolation infrared spectra of trimethylphosphate (TMP) and acetylene (C2H2) were studied in p-H2 and n-H2 matrices and the results were compared with the conventional inert matrices.

    Water exists in two spin isomers, ortho and para, that have different nuclear spin states. In bulk water, rapid proton exchange and hindered molecular rotation obscure the direct observation of two spin isomers. The supramolecular endofullerene H2O@C60 provides freely rotating, isolated water molecules even at cryogenic temperatures. Here we show that the bulk dielectric constant of this substance depends on the ortho/para ratio, and changes slowly in time after a sudden temperature jump, due to nuclear spin conversion. The attribution of the effect to ortho-para conversion is validated by comparison with nuclear magnetic resonance and quantum theory. The change in dielectric constant is consistent with an electric dipole moment of 0.51+/-0.05 Debye for an encapsulated water molecule, indicating the partial shielding of the water dipole by the encapsulating cage. The dependence of bulk dielectric constant on nuclear spin isomer composition appears to be a previously unreported physical phenomenon.

    Background and Purpose Methcathinone (MCAT) is a potent monoamine releaser and parent compound to emerging drugs of abuse including mephedrone (4-CH3 MCAT), the para-methyl analogue of MCAT. This study examined quantitative structure–activity relationships (QSAR) for MCAT and six para-substituted MCAT analogues on (a) in vitro potency to promote monoamine release via dopamine and serotonin transporters (DAT and SERT, respectively), and (b) in vivo modulation of intracranial self-stimulation (ICSS), a behavioural procedure used to evaluate abuse potential. Neurochemical and behavioural effects were correlated with steric (Es), electronic (σp) and lipophilic (πp) parameters of the para substituents. Experimental Approach For neurochemical studies, drug effects on monoamine release through DAT and SERT were evaluated in rat brain synaptosomes. For behavioural studies, drug effects were tested in male Sprague-Dawley rats implanted with electrodes targeting the medial forebrain bundle and trained to lever-press for electrical brain stimulation. Key Results MCAT and all six para-substituted analogues increased monoamine release via DAT and SERT and dose- and time-dependently modulated ICSS. In vitro selectivity for DAT versus SERT correlated with in vivo efficacy to produce abuse-related ICSS facilitation. In addition, the Es values of the para substituents correlated with both selectivity for DAT versus SERT and magnitude of ICSS facilitation. Conclusions and Implications Selectivity for DAT versus SERT in vitro is a key determinant of abuse-related ICSS facilitation by these MCAT analogues, and steric aspects of the para substituent of the MCAT scaffold (indicated by Es) are key determinants of this selectivity.

    This paper discusses the construction and application of reduced-dimensional potential energy surfaces for use in performing simulation of para-hydrogen clusters. Simple spherical averaging and `adiabatic-hindered-rotor' averaging treatments of the angular degrees of freedom are considered and compared.

    Les tumeurs para testiculaires sont des tumeurs rares et complexes qui ont une symptomatologie insidieuse et pauvre. Les formes bénignes représentent 70%. Le lipome para testiculaire étant le type le plus fréquent. L'examen clinique est peu spécifique. L'examen échographique est la pierre angulaire pour assoir le diagnostic. Le traitement chirurgical s'impose en cas de tumeur symptomatique, l'histologie étant habituellement typique permet la confirmation diagnostique. Le pronostic est bon malgré d’éventuelles récidives.

    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

    Sternoclavicular joint dislocation and para-articular fractures of the clavicle are rare injuries. Because severe complications of dorsal dislocations have often been seen and because functional impairment has often followed ventral dislocations, we treat most patients with such injuries operatively. Internal fixation with K-wires frequently leads to severe complications. We present our operation techniques with a resorbable 2 mm polydioxanon cord. This pack up technique can be used in both dislocations and para-articular fractures with no risk of implant dislocation. PMID:8052863

    In this study, poly-para-xylylene-based multifunctional nanoparticles (PPX-NPs) were fabricated. Based on the solubility characteristics determined for asymmetrically substituted poly-para-xylylenes in polar solvents, well-dispersed nanocolloids with a controllable size ranging from 50 to 800nm were produced in solution by the displacement of the solvent (water). These size ranges were found to have acceptable cellular compatibility through examinations of cultured 3T3 fibroblasts and adipose-derived stem cells treated with the PPX-NPs. In addition, these nanoscale PPX-NPs exhibited versatile bioconjugation properties in that a variety of available functional groups can be adopted from their counterpart, thin-film poly-para-xylylenes, during the production of these nanoparticles. For instance, bifunctional PPX-NPs with maleimide and benzoyl moieties were produced to enable immobilization via a maleimide-thiol reaction concurrent with a photochemical reaction. A cleavable PPX-NP was also produced with a thiol-exchangeable surface property. Additionally, by performing electrohydrodynamic jetting of parallel polymer solutions of selected poly-para-xylylenes, Janus-type or multicompartment PPX-NPs were created. The PPX-NPs can potentially be used for various biomedical applications such as combined diagnostics and drug delivery, multiplexing of detection, multiple-drug loading, and the targeted delivery of biomolecules or drugs.

Al ocular móvil de éste se vinculará alguna cámara digital (ST4-ST7-CH250) para lograr la visión del objeto. El funcionamiento del equipo será el siguiente: primero, dadas las coordenadas del objeto a observar, se tomarán las coordenadas del telescopio para que, a través de una base de datos, se determine un campo de objetos que sirvan para la cámara de visión, luego, la PC obtendrá el offset entre la estrella de observación y la estrella seleccionada como guía, este valor será trasladado a los motores que posicionarán en forma automática el ocular. Una vez que la estrella es visualizada en la cámara (monitor de PC ) se correrá el programa que guiará el telescopio automáticamente.

  3. Experimental and theoretical investigation of para-aminophenol ionization in corona discharge

    2015-03-01

    Ionization of para-aminophenol was investigated using an ion mobility spectrometer equipped with a corona discharge as ionization source. The experimental results were confirmed with the use of theoretical method, based on density functional theory. Two peaks were observed in the ion mobility spectrum in the positive ion mode which was corresponded to the protonated isomers of para-aminophenol. It was observed that the relative intensities of the peaks depend on the sample concentration and the nature of the reactant ions. The relative energies of ions derived from protonation of para-aminophenol and its topical proton affinities were determined for different sites in the gas phase. The peak with the lower drift time was assigned to the oxygen protonated isomer and the other peak was ascribed to the nitrogen protonated isomer of para-aminophenol. The calculated dipole moment and localized charge of each isomer were used to verify the ion mobility peak separation. It was shown that combination of theoretical and experimental tools leads to reliable prediction of reactive protonation sites of chemicals in a corona discharge.

  4. Synthesis and properties of para-substituted NCN-pincer palladium and platinum complexes.

    A variety of para-substituted NCN-pincer palladium(II) and platinum(II) complexes [MX(NCN-Z)] (M=Pd(II), Pt(II); X=Cl, Br, I; NCN-Z=[2,6-(CH(2)NMe(2))(2)C(6)H(2)-4-Z](-); Z=NO(2), COOH, SO(3)H, PO(OEt)(2), PO(OH)(OEt), PO(OH)(2), CH(2)OH, SMe, NH(2)) were synthesised by routes involving substitution reactions, either prior to or, notably, after metalation of the ligand. The solubility of the pincer complexes is dominated by the nature of the para substituent Z, which renders several complexes water-soluble. The influence of the para substituent on the electronic properties of the metal centre was studied by (195)Pt NMR spectroscopy and DFT calculations. Both the (195)Pt chemical shift and the calculated natural population charge on platinum correlate linearly with the sigma(p) Hammett substituent constants, and thus the electronic properties of predesigned pincer complexes can be predicted. The sigma(p) value for the para-PtI group itself was determined to be -1.18 in methanol and -0.72 in water/methanol (1/1). Complexes substituted with protic functional groups (CH(2)OH, COOH) exist as dimers in the solid state due to intermolecular hydrogen-bonding interactions. PMID:15034878
