    The objective of this study is to perform a comparative analysis between the Brazilian legislation and internationals protocols, with respect to the quality control tests for computerized tomography. We used 07 references, published from 1998-2012: the Protocolo Brasileiro - Portaria 453/98 SVS/MS and the Guia de Radiodiagnostico Medico da ANVISA; Quality Assurance Programme for Computed Tomography: Diagnostic and Therapy Applications of the IAEA; European Protocol - European Guidelines on Quality Criteria for Computed Tomography of the EUR No. 16262 EN; Radiation Protection No. 162 - Criteria for Acceptability of Medical Radiology, Nuclear Medicine and Radiotherapy of the European Commission; the Protocols of Control de Calidad en Radiodiagnostico IAEA / ARCAL XLIX; and the Protocolo Espanol de Control de Calidad en Radiodignostico. The comparative analysis of these legislations was based on aspects of tolerance / limit, frequency and objectives of the recommended tests. Were found 18 tests in the Brazilian legislation. The tests were grouped according to their nature (dosimetric tests / exposure and geometric tests and image quality tests). Among the evaluated protocols was identified divergence between tests contained in the documents and the criteria of assessment set out in this work. It is clear, moreover, that for certain documents are not observed tolerances, well-defined methodologies and even frequency of testing. We conclude that the current legislation in Brazil differs in certain respects from international protocols analyzed, although this has a great numbers of quality control tests. However, it is necessary that the Brazilian legislation takes into account technological advances presented to time.

    Medical data security can be approached in medico-legal opinioning in three main situations: security of medical data, on which the opinion should be based, opinioning itself and whether the medical data security was properly ensured and ensuring medical data security during medico-legal opinion giving. The importance of medical data security, during collecting, processing and storing, as well in medical as in legal institutions, is of major importance for the possibility of providing a proper medico-legal opinion. Theoretically speeking, it is possible to give a proper medico-legal opinion using incorrect data, but the possibility is low. When the expert is given improper, unreadable, incomplete or even bogus in part or in the whole medical data it is extremely possible, that he fails in giving his opinion. The term "medical data" was defined and subsequently there was a brief review of medical data storing methods made and specific threats bound with them, based on modern literature. The authors also pointed out possible methods of preventing the threats. They listed Polish as well as international regulations and laws concerning the problem, accenting the importance of preserving medical data for the purposes of medico-legal opinioning.

  4. Ethical issues in medico-legal exposures

    O'Reilly, G.; Malone, J. F.

    2008-01-01

    The Medical Exposure Directive (MED) 97/43/Euratom defines medico-legal procedures as 'procedures performed for insurance or legal purposes without a medical indication'. The term 'medico-legal exposures' covers a wide range of possible types of exposures, very different in nature, for which the only feature in common is the fact that the main reason for performing them does not relate directly to the health of the individual being exposed to ionising radiation. The key issue in medico-legal exposures is justification. Balancing the advantages and disadvantages of such exposures is complex because not only can these be difficult to quantify and hence compare, but often the advantage may be to society whereas the disadvantage is usually to an individual. This adds an additional layer of ethical complexity to the problem and one, which requires input from a number of sources beyond the established radiation protection community. Because medico-legal exposures are considered to be medical exposures, they are not subject to dose limits. In medico-legal exposures where the benefit is not necessarily to the individual undergoing the exposure, the question must be asked as to whether or not this is an appropriate framework within which to conduct such exposures. This paper looks at the current situation in Europe, highlighting some of the particular problems that have arisen, and tries to identify the areas, which require further clarification and guidance.

    Clinical skill is an essential part of clinical medicine and plays quite an important role in bridging medicos and physicians. Due to the realities in China, traditional medical education is facing many challenges. There are few opportunities for students to practice their clinical skills and their dexterities are generally at a low level. Medical simulation-based education is a new teaching modality and helps to improve medicos' clinical skills to a large degree. Medical simulation-based education has many significant advantages and will be further developed and applied.

    Whiplash injury (WI) is commonly evaluated in medico-legal practice. With the aim of knowing the determining factors of WI's medico-legal prognosis, a prospective and observational study was carried out. One hundred and twenty consecutive patients who were clinically observed and evaluated in the Medico-Legal Clinic of Barcelona were studied. Socio-demographic, clinical, radiographic and evolutive factors were analyzed. We included 120 patients with a mean age of 35.6 (14) years (range, 4-74), with a homogeneous male/female distribution. An earlier cervical pathology was detected in 10% of patients; none of them had previous psychiatric pathology. 95% corresponded to road-traffic accident cases and there were 5 aggression cases. Over 50% of cases involved a rear-end collision. All patients had neck pain, almost 25% had headache and 13% had paresthesia. According to the Whiplash Association Disorders clinical classification, distribution in grades (G) was: G I 51%, G II 32% and G III 17%. Patients reported recovery within a mean time of 71.6 (46) days (range, 4-244), with 51,2 (45) no working days (range, 0-180 days). The 52% of the patients rest with complains. According to the recovery time, the following medico-legal prognostic factors were identified: age (p legal prognostic factors were age, being females, severity of initial clinical symptoms, previous cervical pathology and abnormal cervical MRI/CT.

    The aim of this work was the implementation of a code of practice for dosimetry in dental radiology using the technique of thermoluminescent dosimetry. General principles for the use of thermoluminescent dosimeters were followed. The irradiations were performed using ten X-ray equipment for intra-oral radiography and an X-ray equipment for panoramic radiography. The incident air kerma was evaluated for five different exposure times used in clinical practice for intra-oral radiographs. Using a backscatter factor of 1.2, it was observed that approximately 40% of the entrance skin dose values found for intra-oral radiographs are above the diagnostic reference level recommended in national regulation. Different configurations of voltage and current were used representing the exposure as a child, woman and man for panoramic radiographs. The results obtained for the air kerma area product were respectively 53.3 +- 5.2 mGy.cm{sup 2}, 101.5 +- 9.5 mGy.cm{sup 2} and 116.8 +- 10.4 mGy.cm{sup 2}. The use of thermoluminescent dosimetry requires several procedures before a result is recorded. The use of dosimeters with ionization chambers or semiconductors provides a simple and robust method for routine measurements. However, the use of thermoluminescent dosimetry can be of great value to large-scale surveys to establish diagnostic reference levels. (author)

    This work has as main purpose to study occupational exposure in diagnostic radiology in medical cases of high doses recorded in 2011 at the national level . These doses were recorded by monitoring individual of the occupationally exposed individuals (OEI's). This monitoring of the doses received by ionizing radiation has as main objective to ensure that the principle of dose limitation is respected. In this study it were evaluated doses of 372 OEI's radiology in different Brazilian states. Doses were extracted from the database of Sector Management Doses of the Institute for Radioprotection and Dosimetry - IRD/CNEN-RJ, Brazil. The information from the database provide reports of doses from several states, which allows to quantify statistically, showing those with the highest doses in four areas: dose greater than or equal to 20 mSv apron and chest and dose greater than or equal to 100 mSv apron and chest. The identification of these states allows the respective Sanitary Surveillance (VISA), be aware of the events and make plans to reduce them. This study clarified the required procedures when there is a record of high dose emphasizing the importance of using protective radiological equipment, dosimeter and provide a safety environment work by maintaining work equipment. Proposes the ongoing training of professionals, emphasizing the relevance of the concepts of radiation protection and the use of the questionnaire with their investigative systematic sequence, which will allow quickly and efficiently the success the investigations.

    It is rare that epidemiological surveys of patients with major trauma include both those admitted to the emergency department and those sent for medico-legal autopsy. The main aim of the present population-based study of major trauma was to examine the importance of medico-legal autopsy data. A new injury severity score (NISS)>15 or lethal outcome was used as criteria for major trauma and to identify patients at the emergency, anaesthesiology and forensic departments and/or being within the jurisdiction of the Malmö police authority and subjected to a medico-legal autopsy between 2011 and 2013. According to Swedish legislation all trauma related deaths should be reported to the police who refer these cases for medico-legal autopsy. Among the 174 individuals included, 92 (53%) died and 81 (47%) underwent medico-legal autopsy. One hundred twenty-six patients were primarily admitted to hospital and 48 died before admission to hospital and were sent directly for medico-legal autopsy. Forty-four in-hospital deaths occurred, of whom 33 (75%) were sent to medico-legal autopsy. In those sent directly to the department of forensic medicine the proportion of accidents was lower (pautopsies among trauma-related deaths at hospital were high age (pautopsy according to legislation, but did not. The high proportion of positive toxicological findings among fatalities examined at medico-legal autopsy implies that toxicology screening should be routine in major trauma patients, in order to improve treatment and prevention.

    Aim: To identify medico-legal issues that occur in the diagnosis and radiological management of breast disease and to propose measures to reduce the risk of patient complaints and legal action in breast radiology and diagnosis. Materials and methods: Institutional review board approval was not applicable for this study. A retrospective study was undertaken and records of 120 medico-legal investigations over a 10 year period were examined. The reports were compiled by two consultant breast radiologists. Results: The mean age of the patients represented in this study was 48.3 years. The main complaint in this series was a delay in diagnosis (92%) followed by inappropriate or inadequate treatment (8%). 81% of cases were patients who had presented to the symptomatic clinic. The main presenting symptom was a palpable lump (65%). Substandard care was cited in 49/120 cases (41%). The mean average delay in diagnosis was 15.6 months. Of the cases cited as substandard care, 61% were considered the fault of the radiologist and 14% considered the fault of the breast surgeon. Of the cases where the radiologist was considered to be at fault, microcalcification was the most common mammographic sign to be missed or misinterpreted (12/26 cases, 46%). Conclusion: The most common complaint in this series was delay in diagnosis with microcalcification being the main mammographic sign that was either not seen or misinterpreted by the radiologist. Clear and precise written protocols are recommended for all breast imaging practice to ensure that medico-legal investigations will be greatly reduced.

We used 07 references, published from 1998-2012: the Protocolo Brasileiro - Portaria 453/98 SVS/MS and the Guia de Radiodiagnostico Medico da ANVISA; Quality Assurance Programme for Computed Tomography: Diagnostic and Therapy Applications of the IAEA; European Protocol - European Guidelines on Quality Criteria for Computed Tomography of the EUR No. 16262 EN; Radiation Protection No. 162 - Criteria for Acceptability of Medical Radiology, Nuclear Medicine and Radiotherapy of the European Commission; the Protocols of Control de Calidad en Radiodiagnostico IAEA / ARCAL XLIX; and the Protocolo Espanol de Control de Calidad en Radiodignostico. The comparative analysis of these legislations was based on aspects of tolerance / limit, frequency and objectives of the recommended tests. Were found 18 tests in the Brazilian legislation. The tests were grouped according to their nature (dosimetric tests / exposure and geometric tests and image quality tests). Among the evaluated protocols was identified divergence between tests contained in the documents and the criteria of assessment set out in this work. It is clear, moreover, that for certain documents are not observed tolerances, well-defined methodologies and even frequency of testing. We conclude that the current legislation in Brazil differs in certain respects from international protocols analyzed, although this has a great numbers of quality control tests. However, it is necessary that the Brazilian legislation takes into account technological advances presented to time

    Clinical photographs are in essence medico-legal records but when instructions are given to take photographs for litigation the requirement is for a more specialized approach than when producing a clinical record for the notes. There are special considerations when providing a medico-legal photographic service, from clients' instructions, preparations before photography, and the photography itself to presenting the photographs and handling the administration. As photographs are taken in support of claims for compensation for personal injury many of them can have far greater impact, financially and psychologically, on the client than clinical photographs. Inadequate coverage could be construed as professional negligence.

    Medico-legal autopsy is conducted routinely in some countries and selectively in others in hospital deaths. This study was conducted to evaluate the views of the forensic medicine experts regarding this matter. A questionnaire pro forma was sent to sixty-five forensic medicine experts practicing in different medical institutions all around India. Designations and experiences of the participants were noted by requests in the same questionnaire. Their specific experience in conducting medico-legal autopsy in hospital deaths was also requested for. Responses were charted in frequency distribution tables and analyzed using SPSS, version 17.0. One-third of the participants felt that a medico-legal autopsy was necessary in all the hospital death cases as defined in the present study. Ten percent of the participants opined that a medico-legal autopsy was unnecessary in hospital deaths. The majority of the experts mentioned finding the cause of death, followed by finding the manner of death and collecting the evidentiary materials, as the reasons for medico-legal autopsy in hospital deaths. Twenty percent of the participants felt that internal findings at autopsy poorly matched with the case records. All the experts agreed that external autopsy findings matched with the hospital case records. Nearly two-third of the participants felt that it was difficult in some cases to interpret the autopsy findings without case records from the hospital where the deceased was treated. Our findings suggest that the exercise of carrying out medico-legal autopsy routinely in every hospital death as evident in the Indian framework is often unnecessary as per the experts' opinion. Autopsy findings in hospital deaths often correlate with hospital case records.

    To optimize conditions of work, mode of life, medico-prophylactic service and hygienic education, a medico-sociologic survey was conducted of miners of deep coal mines to obtain information in order to work up measures to improve health of miners. Results of interrogations of 1000 miners, tunellers and stopers led to the following conclusions: (1) Majority of workers of deep mines of the Donbass notes a warming microclimate at deep horizons, inefficient ventilation, flooding and tediousness of work combined with a nervous-emotional burden. (2) Few miners use respirators, visit inhalators, and follow a rational regime of eating due to shift work. (3) Survey showed negative aspects of life of miners: poor use of holidays, insufficient attention to physical culture and sport, excessive smoking and unwise drinking especially among men of about 30 years of age. Above results of survey demonstrate need for reorganization of an improvement of health education of miners and for organization of more polyclinics for miners. To improve life-style and working conditions, it is necessary to normalize microclimate and reduce dustiness of air, ensure that miners improve their nutrition, improve medico-sanitary service and increase health education propaganda.

    Sudden cardiac death (SCD) in a young athlete represents a dramatic event, and an increasing number of medico-legal cases have addressed this topic. In addition to representing an ethical and medico-legal responsibility, prevention of SCD is directly correlated with accurate eligibility/disqualification decisions, with an inappropriate pronouncement in either direction potentially leading to legal controversy. This review summarizes the common causes of SCD in young athletes, divided into structural (hypertrophic cardiomyopathy, arrhythmogenic cardiomyopathy, congenital coronary artery anomalies, etc.), electrical (Brugada, congenital LQT, Wolf-Parkinson-White syndrome, etc.), and acquired cardiac abnormalities (myocarditis, etc.). In addition, the roles of hereditary cardiac anomalies in SCD in athletes and the effects of a positive result on them and their families are discussed. The medico-legal relevance of pre-participation screening is analyzed, and recommendations from the American Heart Association and European Society of Cardiology are compared. Finally, the main issues concerning the differentiation between physiologic cardiac adaptation in athletes and pathologic findings and, thereby, definition of the so-called gray zone, which is based on exact knowledge of the mechanism of cardiac remodeling including structural or functional adaptions, will be addressed.

    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.

  5. Device for measuring the exposure time in dental X-ray - Cronox

    2009-01-01

    The Centro Regional de Ciencias Nucleares do Nordeste (CRCN-NE) developed a test device for monitoring the X-ray beam in dental equipment to its application in quality control programs. This device, called Odontologic Dosimetric Card (CDO of Cartao Dosimetrico Odontologico in Portuguese) uses thermoluminescent dosimeters (TLD) for the measurement of some parameters of the X-ray beam as the entrance surface dose, the peak tension and half value layer (HVL). Radiographic films record the size of the radiation field. However, the TLD does not allow the assessment of exposure time, a parameter that complements the requirements of the Diretrizes de Protecao Radiologica em Radiodiagnostico Medico e Odontologico of Department of Health in Brazil for such equipment. Thus was developed a system based on sensitivity to ionizing radiation of phototransistors for measurement of exposure time when a patient is put in a clinical dental radiography. The system, called CRONOX was sized to be inserted within the CDO. The results showed that the measuring error had developed for less than 3% when compared to reference values obtained with the Tektronix digital oscilloscope, TDS2022 model. The readings obtained with the CRONOX were also compared with the nominal values selected in the X-ray equipment and with the values measured with the instrument of trade PTW Diavolt Universal. The results showed that the measuring device developed showed a maximum deviation of 5.92% on the nominal value selected, while for the instrument of PTW was 17.86%. (author)

    2017-07-01

    The practice of medicine in India has undergone considerable change affecting delivery of health in both positive and negative directions. As a result, there was a growing feeling that medical treatment should be made accountable and this led to doctors and dentists becoming subject to the process of law. Patients have become more aware of their right to compensation and as a consequence doctors and dentists should be knowledgeable about the laws that govern them. To assess the awareness about Medico legal aspects and Consumer Protection Act [CPA] among Dental professionals. A self-structured validated questionnaire comprising of 20 questions related to medico legal aspects and CPA was designed. A total of 450 dental professionals were surveyed from 4 prime dental institutions in Chennai, India. Of the 450 professionals that were surveyed 150 were MDS faculty, 150 were BDS faculty and 150 were PG students. The data was subjected to SPSS, version 16 and statistically analysed using Chi square test and Fisher's exact test. A- p value less than 0.05 was considered to be statistically significant. BDS faculty, MDS faculty and PG students were found to possess similar level of understanding and there was no significant difference between the groups. Knowledge was found to be equal between male and female dentists. The young practitioners were found to be more informed about CPA than the senior practitioners. It was found that most of the participants were aware of relevant Medico legal aspects, but were less aware of CPA. This study emphasises the need for education relevant to Medico legal aspects and CPA for dental professionals.

  7. Iatrogenic splenic injury: review of the literature and medico-legal issues

    Full Text Available Iatrogenic splenic injury is a recognized complication in abdominal surgery. The aim of this paper is to understand the medico-legal issues of iatrogenic splenic injuries. We performed a literature review on PubMed and Scopus using iatrogenic splenic or spleen injury and iatrogenic splenic rupture as keywords. Iatrogenic splenic injury cases were identified. Most cases were related to colonoscopy, but we also identified cases related to upper gastrointestinal procedures, colonic surgery, ERCP, left nephrectomy and/or adrenalectomy, percutaneous nephrolithotomy, vascular operations involving the abdominal aorta, gynecological operation, left lung biopsy, chest drain, very rarely spinal surgery and even cardiopulmonary resuscitation. There are several surgical procedures that can lead to a splenic injury. However, from a medico-legal point of view, it is important to assess whether the cause can be attributed to a technical error of the operator rather than being an unpredictable and unpreventable complication. It is important for the medico-legal expert to have great knowledge on iatrogenic splenic injuries because it is important to evaluate every step of the first procedure performed, how a splenic injury is produced, and whether the correct treatment for the splenic injury was administered in a judgment.

    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.

    The effective education method of medico-jurisprudence for medical students is unclear. The study was designed to evaluate the effectiveness of problem-based learning (PBL) model teaching medico-jurisprudence in clinical setting on General Law Knowledge (GLK) for medical students. Senior medical students attending either campus-based law curriculum or Obstetrics/Gynecology (Ob/Gyn) clinical setting morning meeting from February to July in 2015 were enrolled. A validated questionnaire comprising 45 questions were completed before and after the law education. The interns attending clinical setting small group improvisation medico-jurisprudence problem-based learning education had significantly better GLK scores than the GLK of students attending campus-based medical law education course after the period studied. PBL teaching model of medico-jurisprudence is an ideal alternative pedagogy model in medical law education curriculum. Copyright © 2017. Published by Elsevier B.V.

    Kunde, Lauren; McMeniman, Erin; Parker, Malcolm

    2013-08-01

    Clinical photography has long been an important aspect in the management of dermatological pathology and has many applications in contemporary dermatology practice. With the continuous evolution of digital and smartphone technology, clinicians must maintain ethical and medico-legal standards. This article reviews how dermatology trainees are utilising this technology in their clinical practice and what procedures they follow when taking photos of patients. We review the ethical and legal considerations of clinical photography in dermatology and present a hypothetical medico-legal scenario. Dermatology registrars were surveyed on their use of personal smartphones and digital equipment for photographing patients in their clinical practice. Numerous medico-legal providers were approached to provide medico-legal advice about a hypothetical scenario. We found that the use of these technologies is prevalent among dermatology registrars and all respondents reported regular use. Clinicians should routinely obtain and document adequate patient consent in relation to clinical photography, utilise strict privacy settings on smartphones and other digital devices and ensure that the images are stored on these devices for minimal periods. Express consent documentation in the clinical file puts the clinician in a more defensible position if a complaint is made to the medical board or privacy commissioner. © 2013 The Authors.

    The show of the display of the inner body has been charming the West for more than five hundred years, but it was only by the end of the 19th century that the invention of radiography allowed a radically new phenomenological experience: peering inside a living body. In the 20th century, medical imaging evolved in a spectacular manner, re-defining the way we see our bodies, literally and metaphorically (think about the new identity of the foetus, promoted by ultrasound imaging, and that of the mind, fostered by functional imaging. In this article, I try to explore some of these transformations, analyzing the work of artists who elaborate very different representations and discourses about the body, but who share the choice of using medical images and technologies.

    Lo spettacolo della messa a vista del corpo interno affascina l’Occidente da oltre cinquecento anni, ma è stato solo sul finire del XIX secolo che l’invenzione della radiografia ha permesso un’esperienza radicale sul piano fenomenologico: guardare dentro a un corpo vivo.

In questo articolo cerco di esplorare alcune di queste trasformazioni, analizzando il lavoro di artisti che ci offrono rappresentazioni e discorsi sul corpo profondamente diversi, ma che sono accomunati dalla scelta di usare nelle loro opere immagini e tecnologie mediche.

    Part 1 of the review "Back to the Future" examines the historical evolution of the medico-legal autopsy and microscopy techniques, from Ancient Civilization to the Post-Genomic Era. In the section focusing on "The Past", the study of historical sources concerning the origins and development of the medico-legal autopsy, from the Bronze Age until the Middle Ages, shows how, as early as 2000 BC, the performance of autopsies for medico-legal purposes was a known and widespread practice in some ancient civilizations in Egypt, the Far East and later in Europe. In the section focusing on "The Present", the improvement of autopsy techniques by Friedrich Albert Zenker and Rudolf Virchow and the contemporary development of optical microscopy techniques for forensic purposes during the 19th and 20th centuries are reported, emphasizing, the regulation of medico-legal autopsies in diverse nations around the world and the publication of international guidelines or best practices elaborated by International Scientific Societies. Finally, in "The Future" section, innovative robotized and advanced microscopy systems and techniques, including their possible use in the bio-medicolegal field, are reported, which should lead to the improvement and standardization of the autopsy methodology, thereby achieving a more precise identification of natural and traumatic pathologies.

  2. Sexual violence legislation in sub-Saharan Africa: the need for strengthened medico-legal linkages.

    2009-11-01

    Six sub-Saharan African countries currently have laws on sexual violence, including Kenya, and eight others have provisions on sexual violence in other legislation. Effective legislation requires functioning medico-legal linkages to enable both justice to be done in cases of sexual violence and the provision of health services for survivors of sexual violence. The health sector also needs to provide post-rape care services and collect and deliver evidence to the criminal justice system. This paper reviews existing data on sexual violence in sub-Saharan Africa, and summarises the content of sexual violence legislation in the region and the strengths and weaknesses of existing medico-legal linkages, using Kenya as a case study. Many sub-Saharan African countries do not yet have comprehensive post-rape care services, nor substantial co-ordination between HIV and sexual and reproductive health services, the legal and judicial systems, and sexual violence legislation. These need to be integrated by cross-referrals, using standardised referral guidelines and pathways, treatment protocols, and medico-legal procedures. Common training approaches and harmonised information across sectors, and common indicators, would facilitate government accountability. Joint and collaborative planning and working at country level, through sharing of information and data between the different systems remain key to achieving this.

    Terranova, Claudio; Bruttocao, Andrea

    2013-10-01

    Diabetic foot is a complex and challenging pathological state, characterized by high complexity of management, morbidity and mortality. The elderly present peculiar problems which interfere on one hand with the patient's compliance and on the other with their diagnostic-therapeutic management. Difficult clinical management may result in medico-legal problems, with criminal and civil consequences. In this context, the authors present a review of the literature, analysing aspects concerning the diagnosis and treatment of diabetic foot in the elderly which may turn out to be a source of professional responsibility. Analysis of these aspects provides an opportunity to discuss elements important not only for clinicians and medical workers but also experts (judges, lawyers, medico-legal experts) who must evaluate hypotheses of professional responsibility concerning diabetic foot in the elderly.

    Full Text Available Forensic odontology is a sub-discipline of dental science which involves the relationship between dentistry and the law. The specialty of forensic odontology is applied in radiographic investigation, human bite marks analysis, anthropologic examination and during mass disasters. Besides the fact that radiographs require pretentious laboratory, it is still claimed to be a facile, rapid, non-invasive method of age identification in the deceased. The budding DNA technology has conquered the traditional procedures and currently being contemplated as chief investigating tool in revealing the hidden mysteries of victims and suspects, especially in hopeless circumstances. Forensic odontology has played a chief role in solving cold cases and proved to be strong evidence in the court of law. Systematic collection of dental records and preservation of the same would marshal the legal officials in identification of the deceased. To serve the forensic operation and legal authorities, dental professionals need to be familiar with the basics of forensic odontology, which would create a consciousness to preserve the dental data. The aim of this paper is to emphasize the vital applications of forensic odontology in medico-legal issues. Conjointly the recent advancements applied in forensic human identification have been updated.

    1. To evaluate the common causes of medico-legal dispute in obstetrics and gynaecology. 2. To assess the potential benefit of early alternative dispute resolution. A prospective analysis of over 500 cases submitted from over 100 solicitors between 1984 and 1994 for medical expert opinion on potential medico-legal claims. Five hundred consecutive cases that met the inclusion criteria: 488 from the United Kingdom and 12 from abroad (Hong Kong, Republic of Ireland). The main principles underlining medico-legal disputes and causes of such claims. Analysis of 500 claims show 46% were misguided allegations, 19% incompetent care, 12% error of judgement, 9% lack of expertise, 7% failure of communication, 6% poor supervision and 1% inadequate staffing. Of the misguided allegations 119/225 cases (59%) were obstetric and 111/275 (40%) cases were gynaecological. The most common cause of obstetric dispute was "cerebral palsy' (22%), while the commonest cause of gynaecological dispute was failed sterilisation (19%). Settled claims were under-reported by solicitors. Because of the high percentage (46%) of misguided allegations, an alternative course of dispute resolution must be a realistic way forward. This course of action, combined with improved communication, could result in a major reduction in the costs of potential medical litigation. Early alternative dispute resolution should be considered in an attempt to reduce the escalating quantum of damages and costs. We recommend recruiting independent, experienced and unbiased consultants in active practice within the appropriate specialty to review such cases at the level of hospital complaints management as an in house review procedure, particularly for small and moderate-sized claims, as a means whereby doctors can retain control of medico-legal disputes, in contrast to control by the legal profession.

    The practice of medical research with minors in Ireland consist of practices pertaining to therapeutic and non-therapeutic medical research. Clinical trials (a category of therapeutic research), is governed by legislation. However, any other therapeutic research (non-clinical trials research) and non-therapeutic research, e.g. observational medical research such as a longitudinal study of children or non-therapeutic research such as blood sample collection for analysis of cause of disease, are unregulated by legislation. This, article will outline and describe some of the medico-legal issues involved in both types of research and will comment on matters such as what national law exists, how the directive on good clinical practice has been implemented, what guidelines, if any, exist.

  18. [Changes of medico-pharmaceutical profession and private practice from the late 19th century to the early 20th century: ebb and flow of western pharmacies and clinics attached to pharmacy].

    Science.gov (United States)

    Lee, Heung-Ki

    2010-12-31

    This article examined i) how traditional medico-pharmaceutical custom from the late 19th century influenced such changes, ii) how medical laws of Daehan Empire and early colonial period influenced the differentiation of medico-pharmaceutical profession, and iii) what the responses of medico-pharmaceutical professionals were like, and arrived at following conclusions. First, in late Chosun, there was a nationwide spread of pharmacies (medicine room, medicine store) as general medical institutions in charge of prescription and medication as well as diagnosis. Therefore, Koreans' perception of Western medicine was not very different from that of traditional pharmacy. Second, Western pharmacies were established by various entities including oriental doctors, Western doctors and drug manufacturers.Their business ranged from medical consultation, prescription, medication and drug manufacture. This was in a way the extension of traditional medico-pharmaceutical custom, which did not draw a sharp line between medical and pharmaceutical practices. Also, regulations on medical and pharmaceutical business of Daehan Empire did not distinguish oriental and Western medicine. Third, clinics attached to pharmacy began to emerge after 1908, as some Western pharmacies that had grown their business based on selling medicine began to hire doctors trained in Western medicine. This trend resulted from Government General's control over medico-pharmaceutical business that began in 1908, following a large-scale dismissal of army surgeons trained in medical schools in 1907. Fourth, as specialization increased within medico-pharmaceutical business following the colonial medical law in early 1910s, such comprehensive business practices as Western pharmacy disappeared and existing businesses were differentiated into dealers of medical ingredients, drug manufacturer, patent medicine businessmen and herbalists. And private practice gradually became the general trend by establishment of medical

    Full Text Available Il presidente della Federazione Nazionale degli Ordini Veterinari Italiani (FNOVI, Gaetano Penocchio, si pone alcune domande: "Chi siamo per il "mondo del lavoro"? Quanto ha bisogno di noi? Siamo preparati a rispondere o a stimolare la domanda di professionalità veterinarie? Come restare competitivi e come garantire nuovi sbocchi occupazionali?". Il nuovo Rapporto sulla professione medico veterinaria, che esce a 4 anni di distanza dal precedente ed è ancora curato da Nomisma, nasce proprio per dare risposta agli interrogativi di cui sopra, proponendosi come strumento informativo aggiornato per il mondo veterinario e per le Istituzioni, nonché come strumento di approfondimento su cui fondare ulteriori riflessioni. Il volume si focalizza soprattutto sui diversi ambiti occupazionali del medico veterinario e sulla dimensione prospettica al 2030 dei possibili scenari evolutivi della professione. Lo "sguardo demoscopico" del Rapporto non prescinde da un dato che deve far riflettere, ovvero che in Italia il rapporto fra popolazione e medici veterinari è (ancora il più alto d'Europa. In vent'anni i veterinari sono raddoppiati fino agli attuali 30.415 di cui il 77% liberi professionisti, quindi esposti al rischio di non avere una continuità lavorativa. Tutto questo, peraltro, nel pieno di spinte recessive che ciclicamente colpiscono il Paese e nel quadro di una crisi globale che si protrae dal 2007. Eppure il Rapporto mette in luce che il 27% delle esportazioni italiane è rappresentato da prodotti alimentari di origine animale e che il comparto della filiera agroalimentare, strettamente connesso alla professione medico veterinaria, ha tenuto contenendo il calo dei consumi alimentari. Una chiave per rilanciare la professione potrebbe essere, ad esempio, quella della specializzazione nell'ambito della sicurezza alimentare: un settore poco curato soprattutto in ambito universitario, come afferma il presidente della FNOVI che chiosa così: "La

    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. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2017-10-01

    The purpose of this work is to better understand the reasons for post-surgical instability and what makes up the bed of medico-legal complications. Beyond technical competence, it is essential to observe a very high degree of rigor in listening to the real motivations in order to give the most accurate possible surgical indications and in particular to know to detect and never to operate certain patients who, whatever we do, will always be dissatisfied. The quality of information is one of the essential elements of prevention: information is part of the care and there is no therapeutic success without a successful relationship between a caregiver and a carereceiver. Before the surgery, it is essential to pre-establish written proof of the proper delivery of the information by signing a receipt and an informed consent document. However, the information does not stop at the time of the operative gesture and it is necessary to be able to provide complete and timely information about any post-surgical complications. Furthermore, aesthetic medicine is well understood and rigorously implemented, contributes to the prevention of surgical and medico-legal complications, reducing the heaviness of certain surgical gestures. The question of e-reputation should in no way be neglected. From this point of view, prevention consists in controlling as much as possible the Internet environment. Indeed, where, in the past, in the presence of a dissatisfied patient awaited us, the fear of word-of-mouth or trial is added to the risk of harm E-reputation whose implications can be very damaging. At a time when the intensive use of the Internet allows anyone to get out of anonymity, we must also control these tools at the risk of sacrificing our expertise at the coronation of amateurs.

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

    The hospital activity of physicians in training mainly consists in direct contacts with patients, tasks indirectly linked to patients such as administration, as well as clinical and theoretical training. In our era of digitalization, an important administrative work load without any added medical value fills their daily chores. In parallel activities of medical secretaries are getting more partitioned, with their desks situated far from physicians' and tasks often limited to finalizing discharge letters. Added to multiple overtime, this reduces physicians' and secretaries' work satisfaction. This article describes the context and development of delegating medico-administrative tasks to secretaries in our department of internal medicine.

    Anaxagoras and Empedocles both established during the Presocratic era a pioneering theory for the creation of everything in the universe. Macrocosmos' impact through the "Four Elements Theory" explained the conglomeration of the blood inside the vessels. Hippocrates, who instituted the "Four Humours theory", clearly understood blood's coagulation and introduced the term "thrombus". Plato, Aristotle and Galen, all engaged with the clotting phenomenon trying to interpret it. After eons of inquiry, it was the innovative thinking of the ancient Greek medico philosophers that set the scientific bases towards the understanding of a process that had been analyzing until our era.

  8. Preventing medico-legal issues in clinical practice

    Full Text Available The medical profession is considered to be one of the noblest professions in the world. The practice of medicine is capable of rendering noble service to humanity provided due care, sincerity, efficiency, and professional skill is observed by the doctors. However, today, the patient–doctor relationship has almost diminished its fiduciary character and has become more formal and structured. Doctors are no longer regarded as infallible and beyond questioning. Corporatization of health care has made it like any other business, and the medical profession is increasingly being guided by the profit motive rather than that of service. On the other hand, a well-publicized malpractice case can ruin the doctor's career and practice. The law, like medicine, is an inexact science. One cannot predict with certainty an outcome of cases many a time. It depends on the particular facts and circumstances of the case, and also the personal notions of the judge concerned who is hearing the case. The axiom “you learn from your mistakes” is too little honored in healthcare. The best way to handle medico-legal issues is by preventing them, and this article tries to enumerate the preventive measures in safeguarding the doctor against negligence suit.

  9. Radiodermatitis. Etiological and medico-legal considerations

    1978-04-01

    This study covers 22 radiodermatitis cases recorded in and around Paris and in industry, from January 1st 1967 to mid-1977, by the health insurance treasury of te Paris region. Special attention was paid to the analysis of their frequency, seriousness and causes and of the medico-legal problems involved. According to our observations these accidents mainly affect radiometallographers, crystallographers, people studying materials by X-fluorescence and technicians responsible for maintenance of medical X-ray radiotherapy machines, the activities most prevalent in the industrial use of ionizing radiations. Three main accident factors are observed: imperfections in the protection system and in the maintenance of equipment; carelessness of personnel towards ionizing radiations owing to the apparent absence of immediate effects; lack of information on the danger of ionizing radiations and on the defensive measures necessary. Three means of protection must be developed as a result: wearing of an extra dosimeter on the wrist or finger; permanent information of staff; checks on equipment and constant improvement in the protection of particularly dangerous instruments (gammagraphs). Acute and chronic radiodermatitis are taken in charge as occupational diseases since they appear in table six of these illnesses with a coverage period of 60 days and 10 years. Radiodermatitis patients face the question of professional reclassification, a difficulty all the greater as their qualifications are high. The possibility of paid professional training for occupational disease victims is especially useful when the subjects are still young [fr

    South Africa manifests a socio-economic dichotomy that shows features of both a developed and developing country. As a result of this, areas exist where a lack of resources and expertise prevents the implementation of a highly standardized protocol for the investigation of sudden and unexpected deaths in infants (SUDI). Although the medico-legal mortuaries attached to academic centers have the capacity to implement standardized protocols, a previous study conducted at two large medico-legal mortuaries indicated otherwise. This study also revealed that the exact number and incidence of sudden infant death syndrome (SIDS) cases was unknown. These findings prompted a multicenter study of the medico-legal investigation procedures and outcomes in five academic centers in South Africa. A retrospective case audit was conducted for a 5-year period (2005-2009) at medico-legal laboratories attached to universities in Bloemfontein, Cape Town-Tygerberg, Durban, Johannesburg, and Pretoria. The total case load as well as the total number of infants younger than 1 year of age admitted to these mortuaries was documented. The case files on all infants younger than 1 year of age who were admitted as sudden and unexpected or unexplained deaths were included in the study population. Data collected on the target population included demographic details, the nature and scope of the post-mortem examinations, as well as the final outcome (cause of death). A total case load of 80,399 cases were admitted to the mortuaries over the 5 year period with a total of 3,295 (6.5 %) infants. In the infant group, 591 (0.7 %) died from non-natural causes and 2,704 (3.3 %) cases of sudden, unexpected and/or unexplained deaths in infants were admitted and included in the detailed case analysis study. One hundred and ninety-nine babies were between 0 and 7 days of age and 210 babies between 8 and 30 days. The remaining 2,295 infants were between 1 month and 12 months of age.

    Full Text Available Spinal cord injuries represent a special category of injuries in traumatic pathology, with high morbidity and mortality, which justify their analysis with the aim to identify useful aspects in order to prevent and treat them. We therefore performed a retrospective study on 426 cases in order to analyze epidemiology and medico-legal issues related to spinal cord injuries. The studied items regarded socio-demographic aspects (gender, age, home region, type of lesions (vertebral, spinal cord, association with other trauma, circumstances leading to trauma (cause of the injury, season, data regarding hospitalization (medical condition at the hospital admission, number of days of hospitalization, clinical diagnosis, imaging exploration level and data resulting from autopsy (diagnosis, toxicological examination. Most of our results are consistent with literature data, except for some epidemiological items, which might be explained with cultural differences, life style and inhomogeneous population. Based on our results, the general conclusion is the need for prevention campaigns, focusing on road traffic accidents and falls (especially in elderly as the main causes of spinal cord injuries.

    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

    There were investigated 453 servicemen--participants of fighting actions in Chechnya [correction of Chechenskaya] Republic in whom the incidence of psychologic stress reactions nearly twice exceeded disorders of other types of psychic dysfunction. 5 groups of combatants were selected and severity of psychic disorders depending on duration of participation in fighting actions was determined. Posttraumatic stress disorders were revealed in 14.5% of servicemen, no signs of psychologic desadaptation were detected in 16.6%, 16.9% had pathologic psychogenic reactions, 18.6% showed pathologic level of psychic disorders, and psychologic stress reactions were noted in 33.4%. The developed individual programs of medico-psychologic rehabilitation depending on type and severity of psychic disorders will allow to reduce the period of restorative treatment and significantly decrease servicemen discharge from the Armed Forces because of psychic disorders.

    Objectives - In France, cancer registries cover 20% of the population. The objective of this study was to provide estimations of thyroid cancer incidence at the administrative district level ( 'departements') over the 2007-2011 period in metropolitan France, using registries data and medico-administrative data. Methods - A medico-administrative indicator 'HUL' [Hospital union LLD] combining Hospital discharge data and health insurance data on Long Duration Diseases (LDD) was constructed. It counts the number of people with a new LDD or hospitalized for thyroid cancer. The principle of the estimation consists in adjusting HUL data at the district level by the Incidence/HUL ratio of the registry area. The accuracy of the estimations was first evaluated in the districts covered by registries by comparing estimated to observed incidence. Results - The preliminary phase of the assessment confirmed that the HUL/Incidence ratio were sufficiently accurate to provide district level estimates of thyroid cancer incidence over the whole territory. The district variability of the estimations for the 2007-2011 period was important: the 5. and 95. percentiles of the distribution of standardized incidence rates across districts were 2.8 and 7.1 for 100,000 in men, and 8.3 and 21.2 for 100,000 in women. Areas with significant over-incidence were observed in the South-East, and on the South-West coast of France compared to the national level. Conclusion - This study confirms the magnitude of geographical variability of thyroid cancer incidence between French administrative districts. It also confirms the value of cross-referencing medico-administrative data to estimate the incidence at an administrative district level. (authors)

    The objective of our study was to determine, in accordance with WHO recommendations, the rates of Caesarean sections in a French perinatal network according to the Robson classification and determine the benefit of the medico-administrative data (PMSI) to collect this indicator. This study aimed to identify the main groups contributing to local variations in the rates of Caesarean sections. A descriptive multicentric study was conducted in 13 maternity units of a French perinatal network. The rates of Caesarean sections and the contribution of each group of the Robson classification were calculated for all Caesarean sections performed in 2014. The agreement of the classification of Caesarean sections according to Robson using medico-administrative data and data collected in the patient records was measured by the Kappa index. We also analysed a 6 groups simplified Robson classification only using data from PMSI, which do not inform about parity and onset of labour. The rate of Caesarean sections was 19% (14.5-33.2) in 2014 (2924 out of 15413 deliveries). The most important contributors to the total rates were groups 1, 2 and 5, representing respectively 14.3%, 16.7% and 32.1% of the Caesarean sections. The rates were significantly different in level 1, 2b and 3 maternity units in groups 1 to 4, level 2a maternity units in group 5, and level 3 maternity units in groups 6 and 7. The agreement between the simplified Robson classification produced using the medical records and the medico-administrative data was excellent, with a Kappa index of 0.985 (0.980-0.990). To reduce the rates of Caesarean sections, audits should be conducted on groups 1, 2 and 5 and local protocols developed. Simply by collecting the parity data, the excellent metrological quality of the medico-administrative data would allow systematisation of the Robson classification for each hospital.

    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. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for diagnostic radiology. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists based in the clinical setting. However, an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement (RCA) for Research, Development and Training related to Nuclear Sciences for Asia and the Pacific. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia-Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specializing in diagnostic radiology started in 2007 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experiences of clinical training programmes in Australia and New Zealand, the UK and the USA, and was moderated by physicists working in the Asian region. This publication follows the approach of the IAEA publication Training Course Series No. 37, Clinical Training of Medical Physicists specializing in Radiation Oncology. This approach to clinical training has been successfully tested in Thailand, with two other Member States currently undergoing testing, and is believed to be applicable to the medical physics community in general.

    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.

    This study investigated the circumstances and problems that departments of forensic medicine encounter with bereaved families regarding samples obtained from medico-legal autopsies. A questionnaire was posted to all 76 departments of forensic medicine performing medico-legal autopsies in Japan, and responses were received from 48 (63.2%). Of the respondents, 12.8% had approached and communicated with bereaved families about collecting samples from the deceased person during an autopsy and the storage of the samples. In addition, 23.4% of these had informed families that samples might be used in research. Eighteen departments had received enquiries and requests from families about the samples, with most requests concerning their return. The response to such requests varied according to the department. Few departments interacted with the bereaved families regarding the procedure for obtaining autopsy samples, and their methods for handling family concerns differed depending on the person within the department authorised to contact the family. Moreover, the procedures for engaging in such communication have long been unclear, and no legal or ethical consensus or agreement with the general public has been established. It is important for researchers to further discuss the correct way for forensic medicine departments to communicate with bereaved families. Published by the BMJ Publishing Group Limited.

    O desenvolvimento de superficies antibacterianas representa um desafio atual em diferentes aplicacoes industriais, nomeadamente, dispositivos medicos, embalagens alimentares, texteis e sistemas de tratamento de agua. A maioria das bacterias existe em biofilmes que aderem fortemente a diferentes tipos de superficies uma vez que esta adesao representa um mecanismo estrategico de sobrevivencia. O fenomeno da adesao e colonizacao microbiana resulta na falha de diferentes dispositivos e componentes utilizados nas aplicacoes acima mencionadas, tendo como consequencia perdas economicas elevadas e representando tambem um problema de saude publica quando se tratam de aplicacoes como dispositivos medicos ou embalagens alimentares. Neste sentido, ao longo das ultimas decadas o desenvolvimento de superficies antibacterianas tem sido considerada uma estrategia emergente no desenvolvimento de materiais mais eficientes a serem aplicados em diferentes sectores. O objetivo da presente tese consiste no desenvolvimento e caracterizacao de revestimentos nanocompositos multifuncionais baseados em revestimentos de carbono amorfo dopado com nanoparticulas de prata (Ag/a-C) para potencial aplicacao em superficies antibacterianas. A Ag e atualmente considerada como o agente bactericida mais promissor e eficiente, sendo que as nanoparticulas de prata representam o material mais comercializado na area da nanotecnologia. A estrategia de modificacao superficial com revestimentos baseados em carbono amorfo (a-C) tem-se tornado popular do ponto de vista industrial essencialmente, devido entre outras propriedades, a sua resistencia ao desgaste tribologico excecional, que permite combinar uma elevada dureza com um baixo coeficiente de atrito, elevada estabilidade quimica, resistencia a corrosao e biocompatibilidade em diferentes aplicacoes biomedicas. Na atualidade os revestimentos de a-C sao utilizados em diferentes aplicacoes industriais nomeadamente dispositivos medicos, laminas de barbear e

    Full Text Available Aim of the study: The paper addresses the use of dental age assessment methods based on radiographs in medico-legal practice. Different cases of practical application of the methods are presented including identification of human remains, dental age assessment in a living person and one archaeological case. Material and methods : The study material consisted of cases involving dental age assessment performed in the Department of Forensic Medicine, Poznan University of Medical Sciences in Poznan. Depending on the preliminary assessment of age, the Liversidge or the Kvaal et al. methods were applied. Dental age was estimated on the basis of available pantomograms. In the case of the living person, it was a radiograph supplied for expert evaluation. In the other cases, dental computed tomography was performed. Results : Dental age was successfully estimated in all of the cases. Various methods based on the analysis of X-ray images were applied. Dental age was shown to be correlated with skeletal age. Conclusions : The methods based on radiographs were demonstrated to be useful, and the results they yield are fully correlated with results of anthropological analyses.

  6. Considerations on the medico-legal compensation for stochastic effects induced by the exposure to ionizing radiations in working environment

    Lafontaine, M.

    1988-01-01

    A better detection of stochastic diseases induced by the exposure to ionizing radiations and the establishment of causative correlation are presently reasons to justify new medico-legal approaches. The right to reparation for workers suffering from diseases which may have been caused by occupational exposure to ionizing radiations in Belgium, is covered by the law on occupational diseases and by the legislation on industrial accidents. However, some difficulties persist, concerning the right for compensation, consisting in the very short delay for prescription, the existence of an administrative list of diseases eligible for compensation and in the burden of proof to establish an obvious etiological relation.

    Sexual assault is a complex situation with medical, psychological, and legal aspects. Forensic experts play a major role in terms of forensic and gynecological medical examination and evidence collection in order to maintain the chain of custody. Victims should be examined by a specially trained medico-legal examiner in order to avoid multiple examinations in the surroundings that do not meet minimum health standards. The evolution and treatment of sexual assault victims are time-intensive and should optimally be provided by a team that includes a forensic medical doctor. These guidelines will be of interest to forensic medical doctors who will have responsibility for the examination and assessment of victims of sexual violence and can be used as a day-to-day service document and/or a guide to develop health service for victims of sexual violence.

    Economic and societal constraints require to take into account the economic dimension and medical performance of hospital departments. We carried out a self-assessment study, which we thought could be useful to share with the neurosurgical community. Care and research activities were assessed from 2009 to 2013. We used institutional and assessment-body parameters in order to describe activities and perform a financial evaluation. It was a retrospective descriptive study based on the guidelines of the DHOS/O4 circular No. 2007/390 of October 29, 2007. The average annual, analytic income statement was +1.39 millions euros, for 63 beds with a 92% occupancy rate, including 6.7 full-time equivalent neurosurgeons (and assistants), for 2553 patients and 1975 surgeries. The average mortality rate was 2.74%. The annual mean length of stay was 6.82 days. Per year, on average 15.6% of patients were admitted in emergency and 76.9% returned home. The annual, act-related-pricing and publication-related incomes represented 77% and 0.6%, respectively of the total funding. Difficulties to find downstream beds for the most severe patients induced 1401 "waiting days" in 2012. Medico-economic analysis of a neurosurgery department at a university hospital was useful in order to take into account the care, teaching and research activities, as well as its related financial value.

    This statistical study was performed to find out the occurrence of accidents on board ships assisted by Centro Internazionale Radio Medico (CIRM) during the years 2010-2015, with the aim of providing suggestions in accident prevention, based on such a wide experience. The case histories of CIRM in the years 2010-2015 were examined. The total number of accidents per year was calculated and compared as a percentage with the total number of cases assisted by CIRM per year. The incidence of accidents on board in these years ranged between 14.4% and 18.4% of total cases assisted per year, which is constantly increasing. The most common injuries on board among cases treated by CIRM were contusions and wounds. Also burns and eye injuries were significantly represented. Multiple injuries and head injuries were found to be the most frequent cause of death on board due to an accident. More information on the occurrence and type of accidents and on the body injured areas should represent the basis for developing strategies and campaigns for their prevention.

    Full Text Available Fluorescence<em> em>>in situ em>hybridization (FISH assay is considered the “gold standard” in evaluating <em>HER2/neu (HER2em> gene status. However, FISH detection is costly and time consuming. Thus, we established nuclei microarray with extracted intact nuclei from paraffin embedded breast cancer tissues for FISH detection. The nuclei microarray FISH (NMFISH technology serves as a useful platform for analyzing <em>HER2em> gene/chromosome 17 centromere ratio. We examined <em>HER2em> gene status in 152 cases of invasive ductal carcinomas of the breast that were resected surgically with FISH and NMFISH. <em>HER2em> gene amplification status was classified according to the guidelines of the American Society of Clinical Oncology and College of American Pathologists (ASCO/CAP. Comparison of the cut-off values for <em>HER2em>/chromosome 17 centromere copy number ratio obtained by NMFISH and FISH showed that there was almost perfect agreement between the two methods (κ coefficient 0.920. The results of the two methods were almost consistent for the evaluation of <em>HER2em> gene counts. The present study proved that NMFISH is comparable with FISH for evaluating <em>HER2em> gene status. The use of nuclei microarray technology is highly efficient, time and reagent conserving and inexpensive.

    Full Text Available Satellite cell activity is necessary for postnatal skeletal muscle growth. Severe phosphate (PO4 deficiency can alter satellite cell activity, however the role of neonatal PO4 nutrition on satellite cell biology remains obscure. Twenty-one piglets (1 day of age, 1.8 ± 0.2 kg BW were pair-fed liquid diets that were either PO4 adequate (0.9% total P, supra-adequate (1.2% total P in PO4 requirement or deficient (0.7% total P in PO4 content for 12 days. Body weight was recorded daily and blood samples collected every 6 days. At day 12, pigs were orally dosed with BrdU and 12 h later, satellite cells were isolated. Satellite cells were also cultured <em>in vitroem> for 7 days to determine if PO4 nutrition alters their ability to proceed through their myogenic lineage. Dietary PO4 deficiency resulted in reduced (<em>P> < 0.05 sera PO4 and parathyroid hormone (PTH concentrations, while supra-adequate dietary PO4 improved (<em>P> < 0.05 feed conversion efficiency as compared to the PO4 adequate group. <em>In vivoem> satellite cell proliferation was reduced (<em>P> < 0.05 among the PO4 deficient pigs, and these cells had altered <em>in vitroem> expression of markers of myogenic progression. Further work to better understand early nutritional programming of satellite cells and the potential benefits of emphasizing early PO4 nutrition for future lean growth potential is warranted.

    The majority (n = 445) of the Israeli and Palestinian fatal victims of the El Aqsah Intifada was examined at the National Center of Forensic Medicine in Tel Aviv. Analysis of the trauma sustained and the anthropologic profile of both the victims and the perpetrators elucidates the trends and contrasts them with the phenomenon in the past. The purpose of the forensic investigation of mass casualty incidents is manifold: establishing the minimal number of individuals involved, identifying the victims and perpetrators, collecting material evidence, and determining the modus operandi. The postmortem examination includes external description of the bodies and their injuries, photo-documentation, and sampling of tissues. Radiography, dental examination, and a ten-print card of each cadaver are also recorded. The modus operandi of the current Intifada is somewhat different from that of the previous wave of terrorism and includes more road shootings and vehicular terrorism. In addition, three suicide bombers who detonated explosive devices within crowded areas were young women, and the age of the perpetrators has increased from up to 35 years to individuals as old as 47, thus greatly enlarging the potential number of suicide terrorists. Virologic and biologic tests have been introduced to examine the tissues of the suicide bombers since they are possible sources of contagion to the wounded victims. The results of the medico-legal investigation of victims and perpetrators of terrorism enable us to establish the modus operandi and the profile of potential perpetrators, which can help in the prevention of similar attacks. Documentation of the different types of injuries in fatal victims of explosion and shooting contributes to improving the awareness of the medical staff treating the wounded of similar attacks. Further investigation into the reliability of virologic and biologic tests conducted on postmortem tissue is recommended.

    An audit of toxicological analysis in Coronial autopsies performed at Forensic Science South Australia was conducted on the cases of three pathologists. Toxicological analysis had been performed in 555 (68 %) from a total of 815 autopsies. It was found that the proffered manner of death was changed from the provisional report (provided immediately after the post-mortem examination) in five cases (just under 1 %) as a consequence of the toxicological findings. This is a limited study as it is retrospective, not all cases had toxicological analysis and the findings are constrained by the range of the substances that could be detected. Nonetheless, the audit supports the application of toxicological analysis in medico-legal death investigation and suggests that an inclusive policy should be adopted.

  14. The necessity of repeated assessment of imaging studies contained in medical records in medico-legal opinions

    Aleksandra Borowska-Solonynko

    2014-12-01

    Full Text Available The paper presents two case reports of living victims, in which imaging studies of the chest conducted at a medical facility were an essential part of the medico-legal opinion. The first case was that of a young male hospitalized due to CT evidence of bilateral rib fractions, who claimed to have been assaulted by police officers. The other case was that of a six week old baby hospitalized due to chest X-ray evidence of right hand side rib fractions. The chest X-ray was performed due to one bruise found on the baby’s forehead and two small bruises on the back, which gave rise to suspicions of child abuse. In both cases, expert witnesses in radiology definitively excluded the presence of any fractures. These cases indicate that a new assessment of imaging studies contained in medical records is needed. Expert opinions based solely on the description of imaging studies may result in grave consequences.

    An optimal correlation between the development tendencies, the popular use of reliable, practically checked technical novelties, the creation and mastering of principally new types of technique and technology is of great value in the development of science and technology programme. This task is solved by logico-semantic modelling. The prospects of the stated approach are conditioned by the possibilities of automatization of the purpose-supposing approach, that during the elaboration of medical scientific and technical programmes leads to reduction of expenditures for carrying out this function, allows to raise the demands for structure and order of program realisation, removes the duplication of search operations and information transmission in the preparatory period, that finally reduces the elaboration time and increases the quality of scientific and technical programme, provides complex approach to medical information problems. The possibilities of the method of logico-semantic modelling are described on the example of structure of the branch scientific and technical programme formation, directed to elaboration of technical and program methods of the system of automatization of medico-biological measuring.

    Full Text Available <em>Eremosparton songoricum em>(Litv. Vass. (<em>E. songoricumem> is a rare and extremely drought-tolerant desert plant that holds promise as a model organism for the identification of genes associated with water deficit stress. Here, we cloned and evaluated the expression of eight candidate reference genes using quantitative real-time reverse transcriptase polymerase chain reactions. The expression of these candidate reference genes was analyzed in a diverse set of 20 samples including various <em>E. songoricumem> plant tissues exposed to multiple environmental stresses. GeNorm analysis indicated that expression stability varied between the reference genes in the different experimental conditions, but the two most stable reference genes were sufficient for normalization in most conditions.<em> EsEFem> and <em>Esα-TUB> were sufficient for various stress conditions, <em>EsEF> and <em>EsACT> were suitable for samples of differing germination stages, and <em>EsGAPDH>and <em>Es>UBQ em>were most stable across multiple adult tissue samples. The <em>Es18Sem> gene was unsuitable as a reference gene in our analysis. In addition, the expression level of the drought-stress related transcription factor <em>EsDREB2em>> em>verified the utility of<em> E. songoricumem> reference genes and indicated that no single gene was adequate for normalization on its own. This is the first systematic report on the selection of reference genes in <em>E. songoricumem>, and these data will facilitate future work on gene expression in this species.

    Full Text Available The mottled skate, <em>Raja pulchraem>, is an economically valuable fish. However, due to a severe population decline, it is listed as a vulnerable species by the International Union for Conservation of Nature. To analyze its genetic structure and diversity, microsatellite markers were developed using 454 pyrosequencing. A total of 17,033 reads containing dinucleotide microsatellite repeat units (mean, 487 base pairs were identified from 453,549 reads. Among 32 loci containing more than nine repeat units, 20 primer sets (62% produced strong PCR products, of which 14 were polymorphic. In an analysis of 60 individuals from two <em>R. pulchra em>populations, the number of alleles per locus ranged from 1–10, and the mean allelic richness was 4.7. No linkage disequilibrium was found between any pair of loci, indicating that the markers were independent. The Hardy–Weinberg equilibrium test showed significant deviation in two of the 28 single-loci after sequential Bonferroni’s correction. Using 11 primer sets, cross-species amplification was demonstrated in nine related species from four families within two classes. Among the 11 loci amplified from three other <em>Rajidae> family species; three loci were polymorphic. A monomorphic locus was amplified in all three <em>Rajidae> family species and the <em>Dasyatidae> family. Two <em>Rajidae> polymorphic loci amplified monomorphic target DNAs in four species belonging to the Carcharhiniformes class, and another was polymorphic in two Carcharhiniformes species.

    A medical and legal review of the literature in regards to the medico legal and de ontological features involved in Imaging Diagnosis of the breast was performed in order to elaborate a series of preventive measures to prevent or reduce the demands on the radiologist. Basically, the contents of the Spanish Medical De ontology Code as well the rules and laws in force in our country have been considered, both from the medical professional point of view as well as from that of the law professional. As a result of the review carried out, a series of preventive measures aimed at reducing the incidence of possible lawsuits against the radiologist who works in breast imaging diagnosis are proposed. The radiologist is regularly involved in lawsuits, especially related with the delay in the diagnosis of breast cancer. In the United States of America and Italy. he(she is the professional who receives the greatest number of lawsuits, being ahead of the gynecologist. The radiologist occupies and important place in the diagnosis of breast cancer, which converts him/her into the object of possible lawsuits. Within these, deadly in the diagnosis of cancer caused by several situations are included: these being, principally, non-detection by mammography, not using the complementary studies and not carrying out an integrated reading of the triad or binomial diagnosis. In some cases, these situations are favored by lack of experience (incompetence) of the radiologists as well as by lack of information from the patient. In order to avoid possible lawsuits, the most important preventive measures are: a) inform the patient; b) be competent in the material: c) follow an action Protocol according to the l ex artis: d) in the case of being staff, comply with the guidelines of Quality Control: e) elaborate clear and concise written reports, maintaining, if relevant, the limitations of the procedures used and suggestions for the professional clinician.

    Degive, Colette; Kos, Maria-Izabel

    2006-01-01

    Because no effective treatment against tinnitus is available, all sorts of approaches have been developed. We believe the care of tinnitus patients concerns mainly ENT medical doctors. In order to take care of such patients, we started in 1993 a joint medico-psychological consultation (JMPC) to dispense adequate care for patients and training to the ENT residents. Every patient visiting our clinic for a tinnitus consultation benefits first from a comprehensive audiological examination. Once all objective causes of tinnitus are excluded, those patients who were not able to accept their auditory disorder or who insist on focusing on the annoyance caused by the perception of their tinnitus are invited by the doctor to the JMPC. The intolerance caused by tinnitus is enhanced by psychological and social aspects. These aspects are considered and discussed during the JMPC. The patients talk about their tinnitus bringing additional information on professional, familial and relational issues. In the JMPC, the therapists try to help the patients to void the affective irritation and the internal tension they clearly demonstrate. When the patients notice that the therapists accept their distress, they usually talk more calmly about their hearing irritation and even consider it tolerable. The medical and psychological information given during the JMPC helps the patients to understand the links between tinnitus and the disturbing elements of their current life. During the JMPC, the medical residents have been able to observe how somatic complaints can lead to complaints of another nature, to distress, to aggressive or angered behaviors. They have acknowledged the way the psychologist deals with the attitudes of these patients. This learning process became mandatory to all our residents specializing in ENT. At the end of their training they should have learned how to help the patient accept the tinnitus and the irritation it causes. They should be able to help tinnitus patients

One badger collected in the area of Imperia turned out to be infected, representing the first report of the parasite in this species in Italy. Further studies are needed to evaluate the role played by fox populations as reservoirs of infection and the probability of its spreading to domestic dogs.

    Full Text Available An efficient method was developed for plant regeneration and establishment from alginate encapsulated synthetic seeds of <em>Rauvolfia serpentinaem>. Synthetic seeds were produced using <em>in vitroem> proliferated microshoots upon complexation of 3% sodium alginate prepared in Llyod and McCown woody plant medium (WPM and 100 mM calcium chloride. Re-growth ability of encapsulated nodal segments was evaluated after storage at 4 °C for 0, 1, 2, 4, 6 and 8 weeks and compared with non-encapsulated buds. Effects of different media <em>viz>; Murashige and Skoog medium; Lloyd and McCown woody Plant medium, Gamborg’s B5 medium and Schenk and Hildebrandt medium was also investigated for conversion into plantlets. The maximum frequency of conversion into plantlets from encapsulated nodal segments stored at 4 °C for 4 weeks was achieved on woody plant medium supplement with 5.0 μM BA and 1.0 μM NAA. Rooting in plantlets was achieved in half-strength Murashige and Skoog liquid medium containing 0.5 μM indole-3-acetic acid (IAA on filter paper bridges. Plantlets obtained from stored synseeds were hardened, established successfully <em>ex vitroem> and were morphologically similar to each other as well as their mother plant. The genetic fidelity of <em>Rauvolfia em>clones raised from synthetic seeds following four weeks of storage at 4 °C were assessed by using random amplified polymorphic<em> em>DNA (RAPD and inter-simple sequence repeat<em> em>(ISSR markers. All the RAPD and ISSR profiles from generated plantlets were monomorphic and comparable<em> em>to the mother plant, which confirms the genetic<em> em>stability among the clones. This synseed protocol could be useful for establishing a particular system for conservation, short-term storage and production of genetically identical and stable plants before it is released for commercial purposes.

    Full Text Available Political and socio-economical destabilization, military conflicts, lack of infrastructure and massive migratory movements formed a current medico-demographic situation in the Republics of Chechnya and Ingushetia: the fertility and birth rates here are very high and exceeds twice the same figures all over the Russian Federation. At the same time the infant mortality and feto-infantile losses rates are also very high. The high fertility leads to overpopulation, low per capita income, worsening of somatic and reproductive women’s and children’s health and consistent increase of reproductive losses. The aging of fertility (in the Republic of Ingushetia and the low level of education (which is typical of the Republic of Chechnya due to the “children of war” achievement of childbearing age and inobservance of optimal intergenetic interval contribute to the aforesaid phenomena. The analysis of pregnant women, women in labour and newborn children state of health shows that according to many characteristics it is worse than at the average in Russia. Feto-infantile losses in the Republics of Chechnya and Ingushetia are more than twice as high as in all over the Russian Federation. One of the most important conditions for the improvement of child-bearing age women and their children is increase of the efficacy of obstetrics and pediatric services in both Republics and family planning.

We here present some ethical-deontological and medical-juridical profiles on the contents of this law and some consideration about its application. Particular attention is dedicated to deontological aspects about industrial safety rules and to medico-legal aspects about occupation under the influence of alcohol, with references to complex relations among worker's discretion right, employer's right to the protection of his own interests and qualified doctor's (or someone to him comparable) right to the respect for the deontological code, with regard to benefit recipient information before the medical treatment. Authors'purpose is to evidence critical points and interpretative ambiguities of a regulation lacking in its practical applications, to provide further proposals of consideration, available to revalue a thematic rich in questions and with a significant social impact.

    Full Text Available Cellulose synthase (CESA, which is an essential catalyst for the generation of plant cell wall biomass, is mainly encoded by the <em>CesA> gene family that contains ten or more members. In this study; four full-length cDNAs encoding CESA were isolated from<em> Betula platyphyllaem> Suk., which is an important timber species, using RT-PCR combined with the RACE method and were named as <em>BplCesA3em>, <em>−4em>,> −7 em>and> −8em>. These deduced CESAs contained the same typical domains and regions as their <em>Arabidopsis> homologs. The cDNA lengths differed among these four genes, as did the locations of the various protein domains inferred from the deduced amino acid sequences, which shared amino acid sequence identities ranging from only 63.8% to 70.5%. Real-time RT-PCR showed that all four <em>BplCesAs> were expressed at different levels in diverse tissues. Results indicated that BplCESA8 might be involved in secondary cell wall biosynthesis and floral development. BplCESA3 appeared in a unique expression pattern and was possibly involved in primary cell wall biosynthesis and seed development; it might also be related to the homogalacturonan synthesis. BplCESA7 and BplCESA4 may be related to the formation of a cellulose synthase complex and participate mainly in secondary cell wall biosynthesis. The extremely low expression abundance of the four BplCESAs in mature pollen suggested very little involvement of them in mature pollen formation in <em>Betula>. The distinct expression pattern of the four <em>BplCesAs> suggested they might participate in developments of various tissues and that they are possibly controlled by distinct mechanisms in <em>Betula.>

    Full Text Available The seeds of <em>Vigna em>genus are important food resources and there have already been many reports regarding their bioactivities. In our preliminary bioassay, the chloroform layer of methanol extracts of<em> V. vexillata em>demonstrated significant anti-inflammatory bioactivity. Therefore, the present research is aimed to purify and identify the anti-inflammatory principles of <em>V. vexillataem>. One new sterol (1 and two new isoflavones (2,3 were reported from the natural sources for the first time and their chemical structures were determined by the spectroscopic and mass spectrometric analyses. In addition, 37 known compounds were identified by comparison of their physical and spectroscopic data with those reported in the literature. Among the isolates, daidzein (23, abscisic acid (25, and quercetin (40 displayed the most significant inhibition of superoxide anion generation and elastase release.

  15. Remaking the medico-legal scene: a social history of the late-Victorian coroner in Oxford.

    2010-04-01

    There have been wide-ranging debates about medicine and the law encapsulated in the figure of the coroner in Victorian England. Recently the historical literature on coroners has been enriched by macro-studies. Despite this important research, the social lives of coroners and their daily interactions remain relatively neglected in standard historical accounts. This article redresses that issue by examining the working life of the coroner for Oxford during the late-Victorian era. Edward Law Hussey kept very detailed records of his time in office as coroner. New research material makes it feasible to trace his professional background, from doctor of the sick poor, to hospital house surgeon and then busy coroner. His career trajectory, personal interactions, and professional disputes, provide an important historical prism illuminating contemporary debates that occupied coroners in their working lives. Hussey tried to improve his medico-legal reach and the public image of his coroner's office by reducing infanticide rates, converting a public mortuary, and acquiring a proper coroner's court. His campaigns had limited success because the social scene in which he worked was complicated by the dominance of health and welfare agencies that resented his role as an expanding arm of the Victorian information state.

    Full Text Available A survey of the carrion fauna was made at two sites in Curitiba, State of Paraná, with the objective of describing the insects associated with carrion and setting up a preliminary data-base for medico-legal purposes in south Brazil. Vertebrate exclusion experiments were carried out in each season between 1994 and 1995 with a 250 g laboratory-bred rat (Rattus norvegicus. Five stages of decomposition were identified: fresh, bloated, decaying, dry and adipocere-like. Some species showed seasonal and site preference and so could be used to identify the probable place and season where death took place. Sarconesia chlorogaster (Diptera, Calliphoridae was restricted to an open field site and to cooler months. Hemilucilia semidiaphana (Diptera, Calliphoridae and Pattonella resona (Diptera, Sarcophagidae were restricted to the forest site and warmer months. Phaenicia eximia (Diptera, Calliphoridae and Oxyletrum discicolle (Coleoptera, Silphidae were present at both sites throughout the year and could be useful for population level analysis. Dissochaetus murray (Coleoptera, Cholevidae was present throughout the year at the forest site and was associated with the adipocere-like stage. Ants played an important role producing post-mortem injuries to the carcasses. Insects of 32 species are reported as being useful in community level approaches

    Full Text Available Ascidians have developed multiple defensive strategies mostly related to physical, nutritional or chemical properties of the tunic. One of such is chemical defense based on secondary metabolites. We analyzed a series of colonial Antarctic ascidians from deep-water collections belonging to the genera <em>Aplidium> and <em>Synoicum> to evaluate the incidence of organic deterrents and their variability. The ether fractions from 15 samples including specimens of the species <em>A.> <em>falklandicum>, <em>A.> <em>fuegiense>, <em>A.> <em>meridianum>, <em>A.> <em>millari> and <em>S.> <em>adareanum> were subjected to feeding assays towards two relevant sympatric predators: the starfish <em>Odontaster> <em>validus>, and the amphipod <em>Cheirimedon> <em>femoratus>. All samples revealed repellency. Nonetheless, some colonies concentrated defensive chemicals in internal body-regions rather than in the tunic. Four ascidian-derived meroterpenoids, rossinones B and the three derivatives 2,3-epoxy-rossinone B, 3-epi-rossinone B, 5,6-epoxy-rossinone B, and the indole alkaloids meridianins A–G, along with other minoritary meridianin compounds were isolated from several samples. Some purified metabolites were tested in feeding assays exhibiting potent unpalatabilities, thus revealing their role in predation avoidance. Ascidian extracts and purified compound-fractions were further assessed in antibacterial tests against a marine Antarctic bacterium. Only the meridianins showed inhibition activity, demonstrating a multifunctional defensive role. According to their occurrence in nature and within our colonial specimens, the possible origin of both types of metabolites is discussed.

    Full Text Available Commercial plant essential oils obtained from 11 Myrtaceae plant species were tested for their fumigant antifungal activity against <em>Aspergillus ochraceusem>, <em>A. flavusem>, and <em>A. nigerem>. Essential oils extracted from<em> em>Leptospermum> <em>petersonii> at air concentrations of 56 × 10−3 mg/mL and 28 × 10−3 mg/mL completely inhibited the growth of the three <em>Aspergillus> species. However, at an air concentration of 14 × 10−3 mg/mL, inhibition rates of <em>L. petersoniiem> essential oils were reduced to 20.2% and 18.8% in the case of <em>A. flavusem> and <em>A. nigerem>, respectively. The other Myrtaceae essential oils (56 × 10−3 mg/mL only weakly inhibited the fungi or had no detectable affect. Gas chromatography-mass spectrometry analysis identified 16 compounds in <em>L. petersoniiem>> em>essential> em>oil.> em>The antifungal activity of the identified compounds was tested individually by using standard or synthesized compounds. Of these, neral and geranial inhibited growth by 100%, at an air concentration of 56 × 10−3 mg/mL, whereas the activity of citronellol was somewhat lover (80%. The other compounds exhibited only moderate or weak antifungal activity. The antifungal activities of blends of constituents identified in <em>L. petersoniiem> oil indicated that neral and geranial were the major contributors to the fumigant and antifungal activities.

    Full Text Available This study was designed to investigate the DNA-methylation status of <em>E>-cadherin (<em>CDH1em> and <em>H>-cadherin (<em>CDH13em> in serum samples of cervical cancer patients and control patients with no malignant diseases and to evaluate the clinical utility of these markers. DNA-methylation status of <em>CDH1em> and <em>CDH13em> was analyzed by means of MethyLight-technology in serum samples from 49 cervical cancer patients and 40 patients with diseases other than cancer. To compare this methylation analysis with another technique, we analyzed the samples with a denaturing high performance liquid chromatography (DHPLC PCR-method. The specificity and sensitivity of <em>CDH1em> DNA-methylation measured by MethyLight was 75% and 55%, and for <em>CDH13em> DNA-methylation 95% and 10%. We identified a specificity of 92.5% and a sensitivity of only 27% for the <em>CDH1em> DHPLC-PCR analysis. Multivariate analysis showed that serum <em>CDH1em> methylation-positive patients had a 7.8-fold risk for death (95% CI: 2.2–27.7; <em>p> = 0.001 and a 92.8-fold risk for relapse (95% CI: 3.9–2207.1; <em>p> = 0.005. We concluded that the serological detection of <em>CDH1em> and <em>CDH13em> DNA-hypermethylation is not an ideal diagnostic tool due to low diagnostic specificity and sensitivity. However, it was validated that <em>CDH1em> methylation analysis in serum samples may be of potential use as a prognostic marker for cervical cancer patients.

    Full Text Available An ultrasound and microwave assisted alternant extraction method (UMAE was applied for extracting dihydroquercetin (DHQ from <em>Larix gmeliniem>i> wood. This investigation was conducted using 60% ethanol as solvent, 1:12 solid to liquid ratio, and 3 h soaking time. The optimum treatment time was ultrasound 40 min, microwave 20 min, respectively, and the extraction was performed once. Under the optimized conditions, satisfactory extraction yield of the target analyte was obtained. Relative to ultrasound-assisted or microwave-assisted method, the proposed approach provides higher extraction yield. The effect of DHQ of different concentrations and synthetic antioxidants on oxidative stability in soy bean oil stored for 20 days at different temperatures (25 °C and 60 °C was compared. DHQ was more effective in restraining soy bean oil oxidation, and a dose-response relationship was observed. The antioxidant activity of DHQ was a little stronger than that of BHA and BHT. Soy bean oil supplemented with 0.08 mg/g DHQ exhibited favorable antioxidant effects and is preferable for effectively avoiding oxidation. The <em>L. gmeliniiem> wood samples before and after extraction were characterized by scanning electron microscopy. The results showed that the UMAE method is a simple and efficient technique for sample preparation.

    Full Text Available We investigated the effect of the parasitic mite <em>Varroa destructorem> on the immunological and nutritional condition of honey bees, <em>Apis melliferaem>, from the perspective of the individual bee and the colony. Pupae, newly-emerged adults and foraging adults were sampled from honey bee colonies at one site in S. Texas, USA. <em>Varroa>‑infested bees displayed elevated titer of Deformed Wing Virus (DWV, suggestive of depressed capacity to limit viral replication. Expression of genes coding three anti-microbial peptides (<em>defensin1, abaecin, hymenoptaecinem> was either not significantly different between <em>Varroa>-infested and uninfested bees or was significantly elevated in <em>Varroa>-infested bees, varying with sampling date and bee developmental age. The effect of <em>Varroa> on nutritional indices of the bees was complex, with protein, triglyceride, glycogen and sugar levels strongly influenced by life-stage of the bee and individual colony. Protein content was depressed and free amino acid content elevated in <em>Varroa>-infested pupae, suggesting that protein synthesis, and consequently growth, may be limited in these insects. No simple relationship between the values of nutritional and immune-related indices was observed, and colony-scale effects were indicated by the reduced weight of pupae in colonies with high <em>Varroa> abundance, irrespective of whether the individual pupa bore <em>Varroa>.

    Full Text Available Abstract In small Mammals biogeography, available data are up to now by far too scanty for elucidate the distribution of a lot of taxa, especially with regard to the absence from a given area. In this respect, standardized quantitative sampling techniques, like Owl pellets analysis can enable not only to enhance faunistic knowledges, but also to estimate the actual absence probability of a given taxon "m", lacking from the diet of an individual raptor. For the last purpose, the relevant frequencies of "m" in the other ecologically similar sites of the same raptor species diets are averaged ($f_m$ : the relevant standard error (multiplicated by a coefficient, according to the desired degree of accuracy, in relation of the integral of probabilities subtracted ($overline{F}_m - a E$: then, the probability that a single specimen is not pertaining to "m" is obtained ($P_0 = 1 - F_m + a E$; lastly, the desiderate accuracy probability ($P_d$ is chosen.

    Forensic medical practitioners need to define the general principles governing procedures to be used for the on-site examination of a body where the death has occurred in unnatural, violent or suspicious circumstances. These principles should be followed whenever a medical expert is required to perform an on-site corpse inspection and should be utilised as a set of general guidelines to be adapted to the specific situation in hand and interpreted using common sense and scientific knowledge of the relevant procedures and facts of the case. The aim of these principles is to ensure that forensic evidence at the scene of a death is properly observed and assessed and all necessary relevant evidence gathered in order to ensure that a comprehensive report is available to the judicial authority (investigating judge or coroner) in the justice system. The on-site corpse inspection by a forensic practitioner is a mandatory and essential stage of the forensic and medico-legal autopsy, as it may provide important information for subsequent investigation stages.

    Creating medico-legal opinion is a sophisticated investigative, analytical, decision-making and creative process. Forensic medicine specialist in cooperation with clinical medicine consultants, on the basis of evidence analysis, which was gathered during procedures and contained in the acts has to create an objective and essential opinion. This opinion is a vital, very important and irreplaceable proof in every case. Judicial body consults with forensic medicine specialist or specialists if there are circumstances for settlement of which there is a need of classified informations - art. 193 of Penalty Code. Forensic medicine specialists face many difficulties which may have effect on quality, positiveness of opinion, compliance with the deadline, increasing expectancy of judicial body or sides. It is very difficult to find clinical specialists which except their clinical knowledge have basic knowledge about law, the role and duties of an court expert. In this article we discuss creating-opinion problems, role and position of court expert in confrontation with expectations of judicial body and the Justice with particular emphasis on medical mistakes and assessment of medical proceedings. We show the complexity of creating of medical opinions, especially these institutional.

    The diversity of necrophagous Diptera is largely unknown in seasonally dry tropical forests, despite their medical, veterinary, and forensic relevance. We performed a study in the dry Caatinga forest exclusive to Brazil in order to assess the diversity and temporal pattern of Diptera species using pig carcasses as substrates. Adults were collected daily until complete skeletonization. We collected 17,142 adults from 18 families, 10 of which comprise species with known necrophagous habits. The most abundant families were Calliphoridae (47.3% of specimens), Sarcophagidae (20.8%), and Muscidae (15.5%), whereas Sarcophagidae stood out in terms of richness with 21 species. The native Cochliomyia macellaria (F.) (Diptera: Calliphoridae) and the invasive Chrysomya albiceps (Wiedmann) (Calliphoridae) were the dominant species. A total of 18 species reached the carcass during the first 48 h postdeath. The bloated and active decay stages had the highest richness and abundance of dipterans. From a forensic standpoint, C. macellaria and C. albiceps are likely to aid in establishing postmortem interval due to their early arrival and high abundance on the carcass. Despite harsh environmental conditions, the Caatinga harbors a rich assemblage of dipterans that play a key role in carrion decomposition. Their medico-veterinary importance is strengthened by the poor local sanitary conditions. © The Authors 2016. Published by Oxford University Press on behalf of Entomological Society of America.

    In 1998 in the Centro de Investigaciones Medico Quirurgicas the Transplant Coordination Office (TCO) was created, with the aim to organize a system to support a hepatic transplantation program. This organization, which changed the transplantation-donation process not only in our center but in the whole country, is described in this article. The files of donors generated in our hospital were studied together with the transplant coordination records, from 1999 till the first half of 2002. In the period studied, 21 potential donors were diagnosed with brain death, yielding a donation rate of 71.4%. Brain death was most frequently caused by vascular brain disease; however, in the realized donor group, the cranioencephalic trauma predominated. The typical donor was a man of average age 39.2 years (range, 18-86 years). Among the potential donors, 24% were excluded based on medical criteria, and 5% due to family objections. Forty liver transplantation were performed in 36 patients including 1 liver-kidney simultaneous procedure. The principal etiologies for transplant included hepatitis C virus cirrhosis, 22%; alcoholic, 19%; and acute hepatic failure, 13%. Kidney transplantations were performed in 70 patients, including 41 from cadaveric donors (53.6%) and 29 from living related donors (41.4%). In 2001, a pancreas-kidney transplantation program was started. The creation of the TCO has been of paramount importance to optimize transplantation program functions.

    Full Text Available Abstract In Italy there are two species of <em>Apodemus> (<em>Sylvaemus>: <em>Apodemus sylvaticusem> on the mainland and the main island, and <em>Apodemus flavicollisem> only on the mainland. The trend of some morphometric characters of the skull (incisive foramen length - FI; interorbital breadth = IO; length of palatal bridge = PP; upper alveolar length = $M^1M^3$ was analized and some theoretical models verified for <em>A. sylvaticusem>. If one considers the sympatric population of <em>A. sylvaticusem> and <em>A. flavicollisem> simultaneously the characters PP, IO and $M^1M^3$ appear significantly isometric being directly correlated ($P leq O.O1$, while FI character results allometric with respect to the previous ones, as expected. If one considers the sympatric populations of each of the species separately, the scenario is different. For <em>A. sylvaticusem> only PP and $M^1M^3$ are isometric ($P leq 0.05$. For <em>A. flavicollisem> only $M^1M^3$ and FI appear to be correlated, although not as significantly as for <em>A. sylvaticusem> ($P le 0.05$; one tail. The insular populations of <em>A. sylvaticusem> do not show significant correlations, except for FI and $M^1M^3$ ($P le 0.05$. On the contrary, considering all populations, sympatric and allopatric, of <em>A. sylvaticusem> at the same time are significant correlations ($P le 0.05$ in all combinations of characters, except for those involving the IO. We suggest that the isometric relations in sympatric assemblages are confined within a morphological range available to the genus <em>Apodemus>. In such a space, the two species are split in two different and innerly homogeneous distributions. We found no evidence to confirm the niche variation hypothesis. On the contrary, the variability expressed as SO or CV's appears higher in the sympatric populations than in the allopatric ones, for three of the four characters, confirming previous results

    Full Text Available An apoptosis correlated molecule—protein Latcripin-1 of <em>Lentinula> edodesem> C91-3—was expressed and characterized in <em>Pichia pastorisem> GS115. The total RNA was obtained from <em>Lentinula edodesem> C91–3. According to the transcriptome, the full-length gene of Latcripin-1 was isolated with 3'-Full Rapid Amplification of cDNA Ends (RACE and 5'-Full RACE methods. The full-length gene was inserted into the secretory expression vector pPIC9K. The protein Latcripin-1 was expressed in <em>Pichia pastorisem> GS115 and analyzed by Sodium Dodecylsulfonate Polyacrylate Gel Electrophoresis (SDS-PAGE and Western blot. The Western blot showed that the protein was expressed successfully. The biological function of protein Latcripin-1 on A549 cells was studied with flow cytometry and the 3-(4,5-Dimethylthiazol-2-yl-2,5-Diphenyl-tetrazolium Bromide (MTT method. The toxic effect of protein Latcripin-1 was detected with the MTT method by co-culturing the characterized protein with chick embryo fibroblasts. The MTT assay results showed that there was a great difference between protein Latcripin-1 groups and the control group (<em>p em>< 0.05. There was no toxic effect of the characterized protein on chick embryo fibroblasts. The flow cytometry showed that there was a significant difference between the protein groups of interest and the control group according to apoptosis function (<em>p em>< 0.05. At the same time, cell ultrastructure observed by transmission electron microscopy supported the results of flow cytometry. The work demonstrates that protein Latcripin-1 can induce apoptosis of human lung cancer cells A549 and brings new insights into and advantages to finding anti-tumor proteins.

    Full Text Available 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.

O abuso sexual, uma das formas mais danosas, é conhecido desde a Antiguidade, porém, pouco se avançou no sentido de prevenir e amenizar suas conseqüências. Diferenças culturais, legais e de procedimentos dos profissionais envolvidos talvez expliquem a dificuldade em se estabelecer políticas públicas de prevenção e enfrentamento do problema no mundo inteiro. O presente estudo realizou uma revisão de publicações sobre abuso sexual contra menores em medicina legal e psiquiatria nos últimos cinco anos. A pesquisa, além dos artigos obtidos nas bases Medline/PubMed e Scielo, utilizou capítulos de livros e textos disponíveis on-line e em bibliotecas. Houve unanimidade entre os autores sobre os malefícios à saúde mental das vítimas e sua adaptação e inserção sociais. É patente a importância do exame médico-legal e dos procedimentos policial e judiciário para o estabelecimento da verdade sobre a ocorrência do abuso sexual. Mais estudos são necessários para conhecer essa realidade: prevalência, incidência, desdobramentos legais e conseqüências futuras.Child and adolescent abuse, as described by Ambroise Tardieu about a century ago, became a subject matter in the last forty years. Sexual abuse, one of the most damaging forms of maltreatment, has been known since Antiquity, but very little has been attained as to the prevention and attenuation of its consequences. Cultural differences, as well as legal questions and those regarding procedures from the involved professionals would perhaps explain the difficult to establish public polices for the world wide prevention and resolution of problem.

    Gindt, Dirk

    2016-01-01

    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.

    Full Text Available In this communication we discuss the development of ionophore based nanosensors for the detection and monitoring of histamine levels <em>in vivoem>. This approach is based on the use of an amine-reactive, broad spectrum ionophore which is capable of recognizing and binding to histamine. We pair this ionophore with our already established nanosensor platform, and demonstrate <em>in vitroem> and <em>in vivoem> monitoring of histamine levels. This approach enables capturing rapid kinetics of histamine after injection, which are more difficult to measure with standard approaches such as blood sampling, especially on small research models. The coupling together of <em>in vivoem> nanosensors with ionophores such as nonactin provide a way to generate nanosensors for novel targets without the difficult process of designing and synthesizing novel ionophores.

    Full Text Available I due <em>Neomys> italiani sono ancora da chiarire dal punto di vista della loro caratterizzazione morfologica e ecologica. Il lavoro prende in considerazione un campione di entrambe le specie proveniente da habitat forestali dell?Appennino settentrionale per i quali sono stati identificati i principali parametri ambientali. Vengono quindi descritte la variabilità dei tratti morfologici delle due specie in aree localizzate nel Parco Nazionale Foreste Casentinesi, Monte Falterona e Campigna nell?Appennino tosco-romagnolo. Risultano di sicuro effetto discriminatorio la maschera facciale, il rapporto piede posteriore/coda e i caratteri cranici. Sulla base dei criteri identificativi si sono realizzate rilevazioni di misure corporee per le due specie e una comparazione degli habitat utilizzati. <em>N. fodiensem> appare unica specie nelle faggete-abetine e dominante nei castagneti, mentre nell?Ontaneta e nelle zone aperte e termofile si registra la sola presenza di <em>N. anomalusem>. Mancano entrambi nei prati cespugliati, nella pecceta e nella cerreta. I gradienti presenti sono quindi illustrati. Non appare una differenza altitudinale nel campione esaminato, posto in stazioni tra i 400 e i 1300 m, ma per entrambe vi sono maggiori riscontri nella fascia tra 700 e 850 m. Nell?analisi multivariata rispetto alle altre specie e alle variabili ambientali si riscontra sempre una discreta correlazione con la presenza di acqua di una certa ampiezza, che comunque è significativa solo per <em>N. fodiensem>, mentre risulta di interesse la positiva correlazione di <em>N. anomalusem> con <em>Apodemus sylvaticusem>.

    Full Text Available Abstract <em>Rhinolophus euryaleem> and <em>R. mehelyiem> are morphologically very similar species and their distributions overlap extensively in the Mediterranean basin. We modelled their foraging behaviour using echolocation calls and wing morphology and, assuming niche segregation occurs between the two species, we explored how it is shaped by these factors. Resting frequency of echolocation calls was recorded and weight, forearm length, wing loading, aspect ratio and wing tip shape index were measured. <em>R. mehelyiem> showed a significantly higher resting frequency than <em>R. euryaleem>, but differences are deemed insufficient for dietary niche segregation. Weight and forearm length were significantly larger in <em>R. mehelyiem>. The higher values of aspect ratio and wing loading and a lower value of wing tip shape index in <em>R. melehyiem> restrict its flight manoeuvrability and agility. Therefore, the flight ability of <em>R. mehelyiem> may decrease as habitat complexity increases. Thus, the principal mechanism for resource partitioning seems to be based on differing habitat use arising from differences in wing morphology.

    Full Text Available A divalent cation-independent lectin—HOL-18, with cytotoxic activity against leukemia cells, was purified from a demosponge, <em>Halichondria okadaiem>. HOL-18 is a 72 kDa tetrameric lectin that consists of four non-covalently bonded 18 kDa subunits. Hemagglutination activity of the lectin was strongly inhibited by chitotriose (GlcNAcβ1-4GlcNAcβ1-4GlcNAc, fetuin and mucins from porcine stomach and bovine submaxillary gland. Lectin activity was stable at pH 4–12 and temperatures lower than 60 °C. Frontal affinity chromatography with 16 types of pyridylaminated oligosaccharides indicated that the lectin had an affinity for <em>N>-linked complex-type and sphingolipid-type oligosaccharides with <em>N>-acetylated hexosamines and neuramic acid at the non-reducing termini. The lectin killed Jurkat leukemia T cells and K562 erythroleukemia cells in a dose- and carbohydrate-dependent manner.

    Full Text Available Environmental exposure to benzene occurs through cigarette smoke, unleaded gasoline and certain types of plastic. Benzene is converted to hematotoxic metabolites by the hepatic phase-I enzyme CYP2E1, and these metabolites are detoxified by the phase-II enzyme NQO1. The genes encoding these enzymes are highly polymorphic and studies of these polymorphisms have shown different pathogenic and prognostic features in various hematological malignancies. The potential role of different cytochrome p450 metabolizing enzymes in the pathogenesis of acute myeloid leukemia (AML in an area of active interest. In this study, we demonstrate aberrant CYP2E1 mRNA over-expression by quantitative real-time polymerase chain reaction in 11 cases of <em>de novoem> AML with inv(16; CBFβ-MYH11. CYP2E1 mRNA levels correlated with <em>CBFβ>-MYH11 em>transcript levels and with bone marrow blast counts in all cases. CYP2E1 over-expression correlated positively with NQO1 mRNA levels (R2 = 0.934, n = 7. By immunohistochemistry, CYP2E1 protein was more frequently expressed in AML with inv(16 compared with other types of AML (<em>p> < 0.001. We obtained serial bone marrow samples from two patients with AML with inv(16 before and after treatment. CYP2E1 mRNA expression levels decreased in parallel with <em>CBFβ>-MYH11 em>transcript levels and blast counts following chemotherapy. In contrast, CYP1A2 transcript levels did not change in either patient. This is the first study to demonstrate concurrent over-expression of CYP2E1 and NQO1 mRNA in AML with inv(16. These findings also suggest that a balance between CYP2E1 and NQO1 may be important in the pathogenesis of AML with inv(16.

    Full Text Available The questions of support of infants with complete and high-quality nutrition as a measure of national medico-social service when switching to artificial or mixed feeding are discussed in the article. The data on the main approaches to support of the infants of the first 3 years of life with specialized nutrition in the Russian Federation is represented. The authors describe such causes of inefficiency of activity of municipal «milk kitchens» as lack of standards for children food products, out of date production technologies, risk of contamination and of breaking the sanitary regulations, irrational usage of resources and low consumer qualities of the service. Necessity of development of new approaches to provide infants with free milk products is demonstrated. Branch target program «Bәlәkәch — Malysh» on free provision of infants of the first 3 years of life with special milk products and milk formulas on pediatrician prescriptions in order to improve the quality of life and health condition, patronized by the President of the Republic of Tatarstan, is characterized, as well as its first results are assessed in the article. The main directions of this program are listed. The comparative characteristic of certain indices of the new scheme of management of free milk nutrition for infants during the period of 2011–2013 are shown. The measures of this program aimed at widening of amount of children receiving free nutrition, increase of quantity of consumed milk products, ensuring of regularity of service, significant decrease of federal resources expenses and providing of precise compliance of standard expanses and improvement of the quality of milk nutrition for children through provision them with appropriate and high-quality products are proved to be very effective.

Nella penisola la specie presenta un areale discontinuo, il cui limite settentrionale è dato dal comune di Manciano (GR, sul versante tirrenico e da una linea che dalla provincia de L'Aquila arriva al Gargano. In Sicilia la distribuzione è relativamente continua anche in aree non protette. Dati genetici hanno permesso di confermare la presenza in Corsica. Al contrario, nell?Isola d'Elba, a seguito di estese ricerche, sono stati identificati solo esemplari di <em>L. europaeusem>. Nell?Italia peninsulare <em>L. corsicanusem> è spesso presente in simpatria con popolazioni di <em>L. europaeusem>, mentre in Sicilia la lepre europea non ha originato popolazioni stabili, nonostante l?immissione di molte migliaia di individui.

    Medico-administrative databases represent a very interesting source of information in the field of endocrine, nutritional and metabolic diseases. The objective of this article is to describe the early works of the Redsiam working group in this field. Algorithms developed in France in the field of diabetes, the treatment of dyslipidemia, precocious puberty, and bariatric surgery based on the National Inter-schema Information System on Health Insurance (SNIIRAM) data were identified and described. Three algorithms for identifying people with diabetes are available in France. These algorithms are based either on full insurance coverage for diabetes or on claims of diabetes treatments, or on the combination of these two methods associated with hospitalizations related to diabetes. Each of these algorithms has a different purpose, and the choice should depend on the goal of the study. Algorithms for identifying people treated for dyslipidemia or precocious puberty or who underwent bariatric surgery are also available. Early work from the Redsiam working group in the field of endocrine, nutritional and metabolic diseases produced an inventory of existing algorithms in France, linked with their goals, together with a presentation of their limitations and advantages, providing useful information for the scientific community. This work will continue with discussions about algorithms on the incidence of diabetes in children, thyroidectomy for thyroid nodules, hypothyroidism, hypoparathyroidism, and amyloidosis.

    Full Text Available Single nucleotide polymorphisms (SNPs are currently the marker of choice in a variety of genetic studies. Using the high resolution melting (HRM genotyping approach, 101 gene-based SNP markers were developed for <em>Apostichopus japonicusem>, a sea cucumber species with economic significance for the aquaculture industry in East Asian countries. HRM analysis revealed that all the loci showed polymorphisms when evaluated using 40 <em>A. japonicusem> individuals collected from a natural population. The minor allele frequency ranged from 0.035 to 0.489. The observed and expected heterozygosities ranged from 0.050 to 0.833 and 0.073 to 0.907, respectively. Thirteen loci were found to depart significantly from Hardy–Weinberg equilibrium (HWE after Bonferroni corrections. Significant linkage disequilibrium (LD was detected in one pair of markers. These SNP markers are expected to be useful for future quantitative trait loci (QTL analysis, and to facilitate marker-assisted selection (MAS in <em>A. japonicusem>.

In this study, the total phenolic content and antioxidant activities of various extract and fractions of stem of <em>R. apiculataem> were investigated. Results indicated that butanol fraction possesses the highest total phenolic content (181.84 mg/g GAE/g dry extract with strongest antioxidant abilities. Following <em>in vitroem> antioxidant activity-guided phytochemical separation procedures, lyoniresinol-3α-<em>O>-β-arabinopyranoside (1, lyoniresinol-3α-<em>O>-β-rhamnoside (2, and afzelechin-3-<em>O>-L-rhamno-pyranoside (3 were separated from the butanol fraction. These compounds showed more noticeable antioxidant activity than a BHT standard in the DPPH, ABTS and hydroxyl radical scavenging assays. HPLC analysis results showed that among different plant parts, the highest content of 13 was located in the bark (0.068%, 0.066% and 0.011%, respectively. The results imply that the <em>R. apiculataem> might be a potential source of natural antioxidants and 13 are antioxidant ingredients in <em>R. apiculataem>.

    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. © 2014 Société Française de Pharmacologie et de Thérapeutique.

    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.

  4. Resins and Gums in Historical Iatrosophia Texts from Cyprus - A Botanical and Medico-pharmacological Approach.

    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.

    Full Text Available Bioenergy is currently regarded as a renewable energy source with a high growth potential. Forest-based biodiesel, with the significant advantage of not competing with grain production on cultivated land, has been considered as a promising substitute for diesel fuel by many countries, including China. Consequently, extracting biodiesel from <em>Jatropha> curcasem> has become a growing industry. However, many key issues related to the development of this industry are still not fully resolved and the prospects for this industry are complicated. The aim of this paper is to evaluate the net energy, CO2 emission, and cost efficiency of <em>Jatropha> biodiesel as a substitute fuel in China to help resolve some of the key issues by studying data from this region of China that is well suited to growing <em>Jatropha>. Our results show that: (1 <em>Jatropha> biodiesel is preferable for global warming mitigation over diesel fuel in terms of the carbon sink during <em>Jatropha> tree growth. (2 The net energy yield of <em>Jatropha> biodiesel is much lower than that of fossil fuel, induced by the high energy consumption during <em>Jatropha> plantation establishment and the conversion from seed oil to diesel fuel step. Therefore, the energy efficiencies of the production of <em>Jatropha> and its conversion to biodiesel need to be improved. (3 Due to current low profit and high risk in the study area, farmers have little incentive to continue or increase <em>Jatropha> production. (4 It is necessary to provide more subsidies and preferential policies for <em>Jatropha> plantations if this industry is to grow. It is also necessary for local government to set realistic objectives and make rational plans to choose proper sites for <em>Jatropha> biodiesel development and the work reported here should assist that effort.

    Despite almost a hundred years of separation, both Cecil B. DeMille’s film <em>The Cheatem> (1915 and John Updike’s novel <em>Terrorist> (2006 deploy a clear-cut territorial divide between Western and Eastern spaces in order to envision a unified American space. These narratives superimpose a “natural” division on these historically opposed spaces and thereby suggest that any contact between these spaces will have dangerous consequences. These consequences include the potential dissolution and eventual destruction of American productivity, surveillance, and territorial integrity. DeMille’s film and Updike’s novel represent America as a nation-state that must be protected from the East. In 1915, <em>The Cheatem> warned against an interracial America and the upsurge in immigration that characterized the turn of the century. Nearly a century later, <em>Terrorist> presupposes an interracial America but still constructs an East that threatens the security of America. While registering the particular concerns of two distinct historical moments, these narratives represent a larger attempt in American aesthetics to imagine an East that jeopardizes the utopian possibilities of an overly idealized American space.

    Full Text Available The knowledge of flavonoids involved in plant-plant interactions and their mechanisms of action are poor and, moreover, the structural characteristics required for these biological activities are scarcely known. The objective of this work was to study the possible <em>in vitro em>phytotoxic effects of 27 flavonoids on the germination and early radical growth of <em>Raphanus sativus em>L.> and <em>Lepidium sativumem> L., with the aim to evaluate the possible structure/activity relationship. Moreover, the antioxidant activity of the same compounds was also evaluated. Generally, in response to various tested flavonoids, germination was only slightly affected, whereas significant differences were observed in the activity of the various tested flavonoids against radical elongation. DPPH test confirms the antioxidant activity of luteolin, quercetin, catechol, morin, and catechin. The biological activity recorded is discussed in relation to the structure of compounds and their capability to interact with cell structures and physiology. No correlation was found between phytotoxic and antioxidant activities.

    A busca por estruturas em grandes escalas (aglomerados de galáxias, por exemplo) é um ativo tópico de pesquisas hoje em dia, pois a detecção de um único aglomerado em altos redshifts pode por vínculos fortes sobre os modelos cosmológicos. Neste projeto estamos fazendo uma busca de estruturas distantes em campos contendo pares de quasares próximos entre si em z Â3 0.9. Os pares de quasares foram extraídos do catálogo de Véron-Cetty & Véron (2001) e estão sendo observados com os telescópios: 2,2m da University of Hawaii (UH), 2,5m do Observatório de Las Campanas e com o GEMINI. Apresentamos aqui a análise preliminar de um par de quasares observado nos filtros i'(7800 Å) e z'(9500 Å) com o GEMINI. A cor (i'-z') mostrou-se útil para detectar objetos "early-type" em redshifts menores que 1.1. No estudo do par 131046+0006/J131055+0008, com redshift ~ 0.9, o uso deste método possibilitou a detecção de sete objetos candidatos a galáxias "early-type". Num mapa da distribuição projetada dos objetos para 22 escala. Um outro argumento em favor dessa hipótese é que eles obedecem uma relação do tipo Kormendy (raio equivalente X brilho superficial dentro desse raio), como a apresentada pelas galáxias elípticas em z = 0.

    Full Text Available The ability of macroencapsulated <em>Saccharomyces cerevisiae em>CBS8066<em> em>to withstand readily and not readily <em>in situem> convertible lignocellulose-derived inhibitors was investigated in anaerobic batch cultivations. It was shown that encapsulation increased the tolerance against readily convertible furan aldehyde inhibitors and to dilute acid spruce hydrolysate, but not to organic acid inhibitors that cannot be metabolized anaerobically. Gene expression analysis showed that the protective effect arising from the encapsulation is evident also on the transcriptome level, as the expression of the stress-related genes <em>YAP1em>, <em>ATR1em> and <em>FLR1em> was induced upon encapsulation. The transcript levels were increased due to encapsulation already in the medium without added inhibitors, indicating that the cells sensed low stress level arising from the encapsulation itself. We present a model, where the stress response is induced by nutrient limitation, that this helps the cells to cope with the increased stress added by a toxic medium, and that superficial cells in the capsules degrade convertible inhibitors, alleviating the inhibition for the cells deeper in the capsule.

The discrimination of these two cryptic species using external characters and measures has proved to be somewhat problematic. We examined two colonies of soprano pipistrelle from Donji Miholjac, Croatia. As a result, only two characters proved to be of help for field identification: wing venation (89% of cases and penis morphology and colour for males. The difference in length between the 2nd and 3rd phalanxes of the 3rd finger should be discarded as diagnostic trait between <em>P. pipistrellusem> and <em>P. pygmaeusem> in Croatia.

    2012-06-01

    Full Text Available The antibacterial activity and mechanism of two kinds of chitosan were investigated against twelve <em>Xanthomonas> strains recovered from <em>Euphorbia pulcherrimaem>. Results indicated that both chitosans markedly inhibited bacterial growth based on OD loss. Furthermore, the release of DNA and RNA from three selected strains was increased by both chitosans. However, the release of intracellular proteins was inhibited by both chitosans at different concentration and incubation times, except chitosan A at 0.1 mg/mL for 0.5 h incubation and 0.2 mg/mL for 2.0 h incubation increased the release of proteins, indicating the complexity of the interaction and cell membranes, which was affected by incubation time, bacterial species, chitosan type and concentration. Transmission electron microscopic observations revealed that chitosan caused changes in protoplast concentration and surface morphology. In some cells, the membranes and walls were badly distorted and disrupted, while other cells were enveloped by a thick and compact ribbon-like layer. The contrary influence on cell morphology may explain the differential effect in the release of material. In addition, scanning electron microscope and biofilm formation test revealed that both chitosans removed biofilm biomass. Overall, this study showed that membrane and biofilm play an important role in the antibacterial mechanism of chitosan.

     Sudden and unexpected death is well known to occur in infants, and although sudden deaths are less frequent after the first birthday, they still account for a significant proportion of childhood deaths. In 2009, 1.9% of the total deaths in the USA were childhood deaths. In South Africa (SA) this proportion was much higher at 11.85%. According to the law, sudden and unexpected deaths are generally investigated as unnatural deaths. Establishing an exact underlying anatomical cause of death will depend on available resources and can be difficult in a substantial proportion of cases.  A retrospective descriptive case audit was conducted at the Pretoria Medico-Legal Laboratory (PMLL), SA, from 1 January 2007 through to 31 December 2011. All children aged 1 - 18 years who died suddenly and unexpectedly were included.  Ninety-eight cases were identified, which constituted nearly 1% of total admissions to the PMLL. The majority of the deaths were of children aged 1 - 5 years, and the male/female ratio was 1.04:1. In the largest proportion of cases (n=28, 28.6%), the medicolegal investigation, including autopsy and ancillary investigations, did not establish an underlying anatomical cause of death. In the cases where a cause of death was established, pneumonia was the most common diagnosis (n=22, 22.4%).  The fact that the cause of the largest proportion of deaths could not be ascertained emphasises the need for consideration of additional investigative techniques, such as molecular/genetic screening, which have provided an underlying cause of death in a significant number of cases in other countries. There is a lack of published research on the causes and incidence of sudden unexpected deaths in children in SA, and further research in this area is needed.

    Full Text Available In traditional Chinese medicine, shikonin and its derivatives, has been used in East Asia for several years for the prevention and treatment of several diseases, including cancer. We previously identified that β,β-dimethylacrylshikonin (DA could inhibit hepatocellular carcinoma growth. In the present study, we investigated the inhibitory effects of DA on human colorectal cancer (CRC cell line HCT-116 <em>in vitroem> and <em>in vivoem>. A viability assay showed that DA could inhibit tumor cell growth in a time- and dose-dependent manner. Flow cytometry showed that DA blocks the cell cycle at G0/G1 phase. Western blotting results demonstrated that the induction of apoptosis by DA correlated with the induction of pro-apoptotic proteins Bax, and Bid, and a decrease in the expression of anti-apoptotic proteins Bcl-2 and Bcl-xl. Furthermore, treatment of HCT-116 bearing nude mice with DA significantly retarded the growth of xenografts. Consistent with the results <em>in vitroem>, the DA-mediated suppression of HCT-116 xenografts correlated with Bax and Bcl-2. Taken together, these results suggest that DA could be a novel and promising approach to the treatment of CRC.

    Full Text Available In order to screen a suitable resin for the preparative simultaneous separation and purification of syringin, eleutheroside E and isofraxidin from <em>Acanthopanax> <em>senticosus>, the adsorption and desorption properties of 17 widely used commercial macroporous resins were evaluated. According to our results, HPD100C, which adsorbs by the molecular tiers model, was the best macroporous resin, offering higher adsorption and desorption capacities and higher adsorption speed for syringin, eleutheroside E and isofraxidin than other resins. Dynamic adsorption and desorption tests were carried out to optimize the process parameters. The optimal conditions were as follows: for adsorption, processing volume: 24 BV, flow rate: 2 BV/h; for desorption, ethanol–water solution: 60:40 (v/v, eluent volume: 4 BV, flow rate: 3 BV/h. Under the above conditions, the contents of syringin, eleutheroside E and isofraxidin increased 174-fold, 20-fold and 5-fold and their recoveries were 80.93%, 93.97% and 93.79%, respectively.

    Full Text Available In Giant Honey Bees, abdomen flipping happens in a variety of contexts. It can be either synchronous or cascaded, such as in the collective defense traits of shimmering and rearing-up, or it can happen as single-agent behavior. Abdomen flipping is also involved in flickering behavior, which occurs regularly under quiescent colony state displaying singular or collective traits, with stochastic, and (semi- synchronized properties. It presumably acts via visual, mechanoceptive, and pheromonal pathways and its goals are still unknown. This study questions whether flickering is preliminary to shimmering which is subject of the <em>fs em>(flickering-shimmering-transition> hypothesis? We tested the respective prediction that trigger sites (<em>ts> at the nest surface (where shimmering waves had been generated show higher flickering activity than the alternative non-trigger sites (<em>nts>. We measured the flickering activity of <em>ts>- and <em>nts>-surface bees from two experimental nests, before and after the colony had been aroused by a dummy wasp. Arousal increased rate and intensity of the flickering activity of both <em>ts>- and <em>nts> cohorts (P < 0.05, whereby the flickering intensity of <em>ts>-bees were higher than that of <em>nts>-bees (P < 0.05. Under arousal, the colonies also increased the number of flickering-active <em>ts>- and <em>nts>-cohorts (P < 0.05. This provides evidence that cohorts which are specialist at launching shimmering waves are found across the quiescent nest zone. It also proves that arousal may reinforce the responsiveness of quiescent curtain bees for participating in shimmering, practically by recruiting additional trigger site bees for expanding repetition of rate and intensity of shimmering waves. This finding confirms the <em>fs-transition> hypothesis and constitutes evidence that flickering is part of a basal colony-intrinsic information system

All had a complementary ALND. For each patient, we calculated the probability of the NSN positivity using the MSKCC nomogram. After validation of this nomogram in the population, we described how the patients' characteristics spread as the threshold value changed. Then, we performed an economic simulation study to estimate the total cost of caring for patients treated according to the MSKCC predictive nomogram results.A 0.3 threshold discriminate the type of sentinel node (SN metastases: 98.8% of patients with pN0(i+ and 91.6% of patients with pN1(mic had a MSKCC score under 0.3 (false negative rate = 6.4%. If we use the 0.3 threshold for economic simulation, 43% of ALND could be avoided, reducing the costs of caring by 1 051 980 EUROS among the 1036 patients.We demonstrated the cost-effectiveness of using the MSKCC NSN prediction nomogram by avoiding ALND for the pN0(i+ or pN1(mic ER+ HER2- breast cancer patients with a MSKCC score of less than or equal to 0.3.

    Full Text Available Eucalyptus bark contains significant amounts of triterpenoids with demonstrated bioactivity, namely triterpenic acids and their acetyl derivatives (ursolic, betulinic, oleanolic, betulonic, 3-acetylursolic, and 3-acetyloleanolic acids. In this work, the supercritical fluid extraction (SFE of <em>Eucalyptus> <em>globulus> deciduous bark was carried out with pure and modified carbon dioxide to recover this fraction, and the results were compared with those obtained by Soxhlet extraction with dichloromethane. The effects of pressure (100–200 bar, co-solvent (ethanol content (0, 5 and 8% wt, and multistep operation were studied in order to evaluate the applicability of SFE for their selective and efficient production. The individual extraction curves of the main families of compounds were measured, and the extracts analyzed by GC-MS. Results pointed out the influence of pressure and the important role played by the co-solvent. Ethanol can be used with advantage, since its effect is more important than increasing pressure by several tens of bar. At 160 bar and 40 °C, the introduction of 8% (wt of ethanol greatly improves the yield of triterpenoids more than threefold.

Plasma membrane repair response is a matter of life and death for human cells against physical and biological damage. We here test the hypothesis that <em>H. pyloriem> also causes plasma membrane disruption injury, and that not only a membrane repair response but also a cell proliferation response are thereby activated. Vacuolating cytotoxin A (VacA and cytotoxin-associated gene A (CagA have been considered to be major <em>H. pyloriem> virulence factors. Gastric cancer cells were infected with <em>H. pyloriem> wild type (vacA+/cagA+, single mutant (ΔvacA or ΔcagA or double mutant (ΔvacA/ΔcagA strains and plasma membrane disruption events and consequent activation of membrane repair components monitored. <em>H. pyloriem> disrupts the host cell plasma membrane, allowing localized dye and extracellular Ca2+ influx. Ca2+-triggered members of the annexin family, A1 and A4, translocate, in response to injury, to the plasma membrane, and cell surface expression of an exocytotic maker of repair, LAMP-2, increases. Additional forms of plasma membrane disruption, unrelated to <em>H.> pylori em>exposure, also promote host cell proliferation. We propose that <em>H. pyloriem> activation of a plasma membrane repair is pro-proliferative. This study might therefore provide new insight into potential mechanisms of <em>H. pyloriem>-induced gastric carcinogenesis.

    In a very famous passage of his <em>Institutes>, the ancient jurist Gaius had divided the Roman Private Law in two parts: the Civil Law and the Law of People. The former is the Law created by the Roman people, whereas the latter is the Law followed by every nation.

    Despite its classical origin, there is some disagreement among specialists about the right way to interpret this distinction. By the beginning of the 20th century, historians like Michel Villey had seen in this distinction the influence of Greek philosophy (Stoic but even Aristotelian among the Roman jurists. But Levy and more recently Kelly have challenged this view and proposed that, in the roman period, philosophers and jurists had completely distinct notions of nature and natural law. The aim of this paper is not to prove the exact influence of Greek philosophy among jurists, but only to suggest that it is not possible to give an interpretation of the classical texts without ascribing to them a theoretical notion of the natural law.

    Full Text Available Abstract To appreciate the influence of the introduction of the Eastern cottontail (<em>Sylvilagus floridanusem> on the food habits of the red fox (Vulpes vulpes, between June 1998 and February 2000 fox diet was investigated by means of scat analysis (N=115 in a 250 ha wide Natural Reserve of NW Italy, and compared with data collected in the same area prior to cottontail colonization (1988-1989. Comparison included also the diet of badgers (<em>Meles melesem>, considered as potential competitors for food resources. Alien lagomorphs (mean percent volume, Vm% = 68% represented by far the most exploited resource, only three other food items reaching values of mean percent volume barely higher than 5%. Cottontails frequency of occurrence did not vary according either to season or to their reproductive cycle (II-IX vs. X-I, whilst diet niche breadth varied inversely proportional to the use of this key-resource. Overall fox trophic niche breadth varied from 0.64 in 1988-89 to 0.31 in 1998-00 (B, Levin’s index. These findings led us to consider the feeding habits of the fox in the study area as a result of local specialization of a typical generalist carnivore, according to the predictions of optimal foraging theory. No variation occurred in the badger niche breadth since cottontail introduction, whilst niche overlap between foxes and badgers decreased from 0.59 to 0.13 (O, Pianka’s index, possibly reducing competition for food in summer.

    In Colombia, citrus, tree tomato and mango crops are likely to suffer considerable losses from anthracnose caused by several <em>Colletotrichum> species, which were identified by the present study on infected organs of the three fruit crops, sampled in different regions of the country. Identification was based on their morphological and molecular characteristics, as well as on fungicide (benomyl and copper hydroxide sensitivity and pathogenicity tests. The latter assessed infectivity on both the original hosting crop and the other two crops (crossed infection, by putting the fungi in contact with organs taken from the three fruit crops. Molecular identification of the <em>Colletotrichum> species was carried out through amplification of rDNA ITS regions by means of <em>C. gloeosporioidesem> (CgInt and <em>C. acutatumem> (CaInt2 specific primer PCR combining the use of ITS4 universal primer. The results indicate that <em>C. acutatumem> is the infectious agent in Tahiti lime and tree tomato, and so is <em>C. gloeosporioidesem> in mango. Although <em>C. acutatumem> is the infectious agent in two diferent fruit species, the strains proved to be specific of their original hosts.

    Since 1987, the nursery specialization degrees, such as Radiology and Electrotechnical were cancelled. Afterwards, an education and training deficiency has existed in the nursery career. The professional college of Graduated in Nursery in Seville, recognized the lack of training in their members to develop properly the profession, specially in radiation protection within the radiodiagnosis area. Therefore, advanced training courses were organised by this college to overcome the training deficiency and to provide skills for the correct management of the radiodiagnosis facilities. These courses are accredited by the Spanish Nuclear Safety Council. These courses have been performing annually since 1994 and cover the following items: Theoretical content: Electromagnetic Radiations. Radiobiology. Radiation Protection. Laws and Legislation. Seminaries. Practical content: Radiation Monitors. Evaluation of a X-ray room shielding. Quality control of the x-ray films and direct beam radiation. Seminaries. More than 300 nursery professionals ha been trained by these courses. They have acquired enough knowledge to offer radiological safety to their users within the ALARA frame, in state and private establishments. (Author) 4 refs.

    The aim of the study was to analyze the incidence of acetone and isopropanol in the blood of the deceased, and to assess cases in which the compounds have been detected with a focus on their origin and usefulness for medico-legal testimony. The study material consisted of results of tests detecting ethyl alcohol and reports of autopsies performed at the Department of Forensic Medicine, Medical University of Warsaw, from January 2008 to April 2009 - a total of 2,475 cases. The test group proper (group B) comprised only those cases in which acetone was detected in blood, either with or without isopropanol [n = 202 (8.2%)]. The blood levels of isopropanol varied depending on the cause of death. The need for differentiating the origin of isopropanol in the case of its presence in the blood of the deceased was pointed out. The results of the present study show that the differentiation should be based on the isopropanol and acetone concentration ratio, as isopropanol concentration alone is not sufficient for preparing expert opinions. Even high concentrations of isopropanol, when accompanied by even higher concentrations of acetone, imply that isopropanol could have been formed as a result of acetone transformations. Isopropanol concentrations exceeding acetone levels strongly point to the exogenous origin of isopropanol, particularly when high levels of ethanol are concurrently detected.

    Full Text Available <em>Vulpes vulpesem> (Linnaeus, 1758 is one of the most common carnivore in Italy and its spread includes almost the whole national territory. The species shows an high ecological plasticity and a variable diet composition connected in part to human sources. This high adaptability permits the red foxes to colonize different habitats like the suburbs of large cities as well as the small villages located in mountain areas. On the other hand, the tourism pressure seems to assume a great importance in the Alps, also in those areas where the foxes live. So, indirect interactions could take place between these animals and the humans. The role of <em>V. vulpesem> in the zoonoses has not to be understated since this carnivore could transmit parasitic diseases that are able to cause serious pathologies in humans. This study aims just to investigate on intestinal communities of helmiths of <em>V. vulpesem> in order to make progress in current knowledge on epidemiological situation in Italian Alps. During 1998-2003, we have examined 450 foxes from Trentino Alto Adige, Veneto, Lombardia and Valle d'Aosta. The specimens collected were found dead or have been hunted (according to national law n. 157/92 in localities situated between 170 and 2200 m a.s.l.

    Full Text Available <em>Pp>CHS is a member of the type III polyketide synthase family and catalyses the synthesis of the flavonoid precursor naringenin chalcone from <em>p>-coumaroyl-CoA. Recent research reports the production of pyrone derivatives using either hexanoyl-CoA or butyryl-CoA as starter molecule. The Cys-His-Asn catalytic triad found in other plant chalcone synthase predicted polypeptides is conserved in <em>Pp>CHS. Site directed mutagenesis involving these amino acids residing in the active-site cavity revealed that the cavity volume of the active-site plays a significant role in the selection of starter molecules as well as product formation. Substitutions of Cys 170 with Arg and Ser amino acids decreased the ability of the <em>Pp>CHS to utilize hexanoyl-CoA as a starter molecule, which directly effected the production of pyrone derivatives (products. These substitutions are believed to have a restricted number of elongations of the growing polypeptide chain due to the smaller cavity volume of the mutant’s active site.

    2016-09-01

    Full Text Available Health, demographic and environmental consequences of 1998 and 2008 economic crises for the Ural Federal District are considered in the paper. Regional resilience is defined as the ability of a regional socio-economic system to withstand, absorb or overcome an internal or external economic shock. The quantitative analysis of regional resilience of the subject entities of the Ural Federal District is based on two interrelated dimensions: resistance, those are the vulnerability or sensitivity of a regional socio-economic system to disturbances and disruptions; and the speed and extend of recovery from such a disruption. Because resilience as a concept captures resistance to the shock and recovery from it, resistance indexes and recovery indexes are used for assessing the impact of regions to recessionary shocks. Three sets of resilience indicators were used: economic, environmental and medico-demographic ones. The main criteria for selecting resilience indicators were their robustness as a measure of the territorial impact of the economic crisis and availability of long time series. Special attention is paid to the question identification of the qualitative and quantitative factors, which form the territorial characteristics enabling some regions to resist, or move out of, economic downturn more effectively than others. Unfortunately, a valid answer to the question why some regions are more able to withstand an economic downturn than others, or are able to recover faster, cannot be given at present. Resilience to an economic shock does not necessarily imply that the economy is otherwise strong and performing well over the longer-term. Regions that experience strong economic growth prior to a shock may appear to be less resilient. Such components of the regional socio-economic system as reserves of natural resources, sectoral structure of regional economy, skills of population, diversified economy and quality of governance do not define uniquely

    Full Text Available The dinoflagellate <em>Gymnodinium catenatumem> produces paralyzing shellfish poisons that are consumed and accumulated by bivalves. We performed short-term feeding experiments to examine ingestion, accumulation, biotransformation, histopathology, and paralysis in the juvenile Pacific calico scallop <em>Argopecten ventricosusem> that consume this dinoflagellate. Depletion of algal cells was measured in closed systems. Histopathological preparations were microscopically analyzed. Paralysis was observed and the time of recovery recorded. Accumulation and possible biotransformation of toxins were measured by HPLC analysis. Feeding activity in treated scallops showed that scallops produced pseudofeces, ingestion rates decreased at 8 h; approximately 60% of the scallops were paralyzed and melanin production and hemocyte aggregation were observed in several tissues at 15 h. HPLC analysis showed that the only toxins present in the dinoflagellates and scallops were the <em>N>-sulfo-carbamoyl toxins (C1, C2; after hydrolysis, the carbamate toxins (epimers GTX2/3 were present. C1 and C2 toxins were most common in the mantle, followed by the digestive gland and stomach-complex, adductor muscle, kidney and rectum group, and finally, gills. Toxin profiles in scallop tissue were similar to the dinoflagellate; biotransformations were not present in the scallops in this short-term feeding experiment.

    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.

    Full Text Available Abstract Little is known on the ecology and behaviour of alpine mountain hare (<em>Lepus timidusem>. Between 1996 and 1997 we analysed by radiotracking the pattern of space use of 8 mountain hares from the Swiss Alps. We estimated home range size using both the kernel density estimator and the minimum convex polygon. We found smaller ranges (38 ha compared to those reported for the species in boreal or arctic habitats, but similar to ranges in Scotland. Hares did not use a centre of major activity (core area and showed high home range overlap, confirming their non-territorial behaviour. Smaller ranges were used during winter compared to the other seasons, whilst no difference in size was found between sexes.

We examined roost selection in a breeding population of <em>B. barbastellusem> from the Abruzzo Lazio and Molise National Park (central Italy at three levels: woodland structure and management type; tree characteristics; and cavity characteristics. In 2001-2002, we fitted 31 adult <em>B. barbastellusem> (29 lactating females, one pregnant female and one male with 0.48g radio-tags and tracked them to their roost-trees. The bats were tracked for 4.5 ± 3.7 days (range: 0-12 days. We located 33 roosts used by 25 subjects (1.8±1.2 roosts/bat, range 1-5. The bats switched roosts frequently: 13 bats used more than one tree over the study period. A chi-square analysis showed that the roosts were not distributed at random across woodland categories: unmanaged woodland was positively selected, whereas shelterwood-harvested woodland was used in proportion to its availability, and ?pastures+scattered trees? was avoided. Twenty out of 33 roost trees were dead <em>Fagus sylvaticaem> trees; conversely, living <em>F. sylvaticaem> dominated in a tree sample obtained at random; dead trees were used more than expected (Χ² test, <em>P> <0.001.

The broth microdilution assay was used to determine the minimal inhibitory concentrations (MICs and minimal bactericidal concentrations (MBCs of ISJ alone. The results showed that its MICs/MBCs ranged from 4/16 to 16/64 μg/mL, with the concentrations required to inhibit or kill 50% of the strains (MIC50/MBC50 at 8/16 μg/mL. Synergistic evaluations of this compound with four conventional antibacterial agents representing different types were performed by the chequerboard and time-kill tests. The chequerboard method showed significant synergy effects when ISJ was combined with Ceftazidime (CAZ, Levofloxacin (LEV and Ampicillin (AMP, with the values of 50% of the fractional inhibitory concentration indices (FICI50 at 0.25, 0.37 and 0.37, respectively. Combined bactericidal activities were also observed in the time-kill dynamic assay. The results showed the ability of ISJ to reduce MRSA viable counts by log10CFU/mL at 24 h of incubation at a concentration of 1 × MIC were 1.5 (LEV, additivity, 0.92 (CAZ, indifference and 0.82 (AMP, indifference, respectively.

    Full Text Available La martora, <em>Martes martesem>, è un mustelide storicamente presente su gran parte del territorio italiano, soprattutto dove siano presenti foreste mature altamente strutturate e ricche di risorse. Nel corso dei decenni passati, cause quali la deforestazione con conseguente frammentazione dell'habitat, la caccia e la persecuzione da parte dell'uomo hanno portato ad un sensibile declino sia nel numero d'individui sia di popolazioni in tutta l'Europa. Frammentazione degli areali e diminuzione del numero di soggetti costituiscono le cause principali di un limitato flusso genico con conseguente formazione di popolazioni isolate di martora e perdita di variabilità genetica (Kyle <em>et al.em>, 2003. Per queste ragioni la martora risulta attualmente tutelata secondo quanto previsto dalla Convenzione di Berna (appendice III e dalla Direttiva europea 92/43/CEE "Habitats & Species". Di fronte a prospettive di tipo conservazionistico, diventa necessario disporre di metodologie per la valutazione della variabilità residua nella specie a livello d'individui e di popolazioni. Secondo numerosi Autori, i microsatelliti costituiscono marcatori molto efficaci nella descrizione della struttura genetica e della storia demografica di specie (Beaumont & Bruford, 1999; Linares, 1999.

Buscamos, em primeiro lugar, uma definição estética do que seria um retrato cinematográfico, sempre em tensão com os critérios formais e padrões estilísticos que historicamente constituíram o retrato pictórico. Em seguida, relacionamos essa questão com a importância que se deu à representação do close-up de rosto nas primeiras décadas do cinema, quando foi atribuído aos filmes um papel inédito no estudo da fisionomia e da expressão facial. Por fim, apresentamos exemplos de autorretratos na pintura e no cinema para expor a forma como a autorrepresentação põe em crise as noções de subjetividade e identidade em que a definição clássica do retrato se apoiava.

    This study used medico-legal data to investigate fatal older road user (ORU, aged 65 years and older) crash circumstances and risk factors relating to 4 key components of the Safe System approach (e.g., roads and roadsides, vehicles, road users, and speeds) to identify areas of priority for targeted prevention activity. The Coroners' Court of Victoria's (CCOV) Surveillance Database was searched to identify and describe the frequency and rate per 100,000 population of fatal ORU crashes in the Australian state of Victoria for 2013-2014. Information relating to the deceased ORU, crash characteristics and circumstances, and risk factors was extracted and analyzed. One hundred and thirty-eight unintentional fatal ORU crashes were identified in the CCOV Surveillance Database. Of these fatal ORU crashes, most involved older drivers (44%), followed by older pedestrians (32%), older passengers (17%), older pedal cyclists (4%), older motorcyclists (1%), and older mobility scooter users (1%). The average annual rate of fatal ORU crashes per 100,000 population was 8.1 (95% confidence interval [CI], 6.0-10.2). In terms of the crash characteristics and circumstances, most fatal ORU crashes involved a counterpart (98%), of which the majority were passenger cars (50%) or fixed/stationary objects (25%), including trees (46%) or embankments (23%). In addition, most fatal ORU crashes occurred close to home (73%), on-road (87%), on roads that were paved (94%), on roads with light traffic volume (37%), and during low-risk conditions: between 12 p.m. and 6 p.m. (44%), on weekdays (80%), during daylight (75%), and under dry/clear conditions (81%). Road user (RU) error was identified by the police and/or the coroner for the majority of fatal crashes (55%), with a significant proportion of deceased ORUs deemed to have failed to yield (54%) or misjudged (41%). RU error was the most significant factor identified in fatal ORU crashes, which suggests that there is a limited capacity of the

    This paper reviews medical activity provided from 1996 to 2000 by the International Radio Medical Centre (Centro Internazionale Radio Medico, C.I.R.M.). C.I.R.M. is a non-profit organization headquartered in Rome and providing freely telemedical advice to ships flying of any flag navigating on all seas of the world, to civil airplanes and to small Italian islands. From 1996 to 2000 C.I.R.M. has assisted 4,982 patients, 4,686 of which (94%) on board ships, 85 on airplanes and 206 on small Italian islands. More than 65% of requests of telemedical advice received by C.I.R.M. were from non-Italian ships. This indicates the really international nature of C.I.R.M.'s activity. The largest number of medical requests come from the Atlantic Ocean, followed by the Mediterranean sea, Indian Ocean and Pacific Ocean. In terms of pathologies assisted, accidents took the first place, followed as main pathologies by gastrointestinal disorders, cardiovascular pathologies, respiratory disorders, infectious and parasitic diseases and nervous system complaints. Analysis of the outcome of C.I.R.M.'s medical activity showed that more than 50% of patients assisted were recovered or improved while assisted by the Centre.

    The meaning of the term "medico competente" - usually adopted in Italy to indicate the occupational physician - is little known. To describe the origins of the word "medico competente" in Italy. We conducted a comprehensive analysis of the Italian legislation from the end of the nineteenth century to the present day. In the United Kingdom, occupational physicians were originally named as "certifying surgeon" (1833) and "appointed surgeon" (1860). In Italy, the term "medico delegato" was introduced to indicate the physician who visited child laborers (1886), while the word "medico competente" was first used in some propaganda leaflets of the Clinica del Lavoro of Milan in 1910. This term was officially used in Italian legislation in 1927 and was preferred to "medico di fabbrica" (factory physician) in the post-World War II period. Since 1982, the term "medico competente" has started to be considered as a synonym of occupational physician in Italian laws. The name "medico competente" appears to derive from a legislative imposition rather than from a voluntary choice developed in a medical and scientific context. Nowadays, Italian occupational physicians should be stimulated to find scientific, ethical, and professional meanings in this term, so helping to enhance their figure in modern society.

    Suicide among nursing home residents is a growing public health concern, currently lacking in empirical research. This study aims to describe the frequency and nature of suicide among nursing home residents in Australia. This research comprised a national population-based retrospective analysis of suicide deaths among nursing home residents in Australia reported to the Coroner between July 2000 and December 2013. Cases were identified using the National Coronial Information System, and data collected from paper-based coroners' records on individual, incident, and organizational factors, as well as details of the medico-legal death investigation. Data analysis comprised univariate and bivariate descriptive statistical techniques; ecological analysis of incidence rates using population denominators; and comparison of age and sex of suicide cases to deaths from other causes using logistic regression. The study identified 141 suicides among nursing home residents, occurring at a rate of 0.02 deaths per 100 000 resident bed days. The ratio of deaths from suicide to deaths from any other cause was higher in males than females (OR = 3.56, 95%CI = 2.48-5.12, P = home for less than 12 months (n = 71, 50.3%). Common major life stressors identified in suicide cases included the following: health deterioration (n = 112, 79.4%); isolation and loneliness (n = 60, 42.6%); and maladjustment to nursing home life (n = 42, 29.8%). This research provides a foundational understanding of suicide among nursing home residents in Australia and contributes important new information to the international knowledge base.

    Full Text Available The purpose of the study was to investigate the antioxidant characteristics of <em>Anisomeles indicaem> methanol extract and the inhibitory effect of ovatodiolide on melanogenesis. In the study, the antioxidant capacities of <em>A. indicaem> methanol extract such as DPPH assay, ABTS radical scavenging assay, reducing capacity and metal ion chelating capacity as well as total phenolic content of the extract were investigated. In addition, the inhibitory effects of ovatodiolide on mushroom tyrosinase, B16F10 intracellular tyrosinase and melanin content were determined spectrophotometrically. Our results revealed that the antioxidant capacities of <em>A. indicaem> methanol extract increased in a dose-dependent pattern. The purified ovatodiolide inhibited mushroom tyrosinase activity (IC50 = 0.253 mM, the compound also effectively suppressed intracellular tyrosinase activity (IC50 = 0.469 mM and decreased the amount of melanin (IC50 = 0.435 mM in a dose-dependent manner in B16F10 cells. Our results concluded that <em>A. indicaem> methanol extract displays antioxidant capacities and ovatodiolide purified from the extract inhibited melanogenesis in B16F10 cells. Hence, <em>A. indicaem> methanol extract and ovatodiolide could be applied as a type of dermatological whitening agent in skin care products.

    “Locas al Rescate: The Transnational Hauntings of Queer <em>Cubanidad>” (originally published in <em>Cuba Transnationalem> offers a significant contribution both to transnational American Studies and to gender studies. In telling the insider story of the alternative identity formation, practices, and forms of “rescue” initiated by the affective activism of the Cuban American society in drag in 1990s Miami/South Beach, Lima resuscitates the liberatory gestures of a subculture defined by its pursuit of its own acceptance, value, and freedom. With their aesthetic and political life on a raft, the gay micro-communities inside Cuban America asserted their own islandic space, Lima observes, performing “takeovers” in and of parks and bars and beaches—creating a post-Habermasian sphere of public activism focused on private parts, saving themselves from AIDS, from the disaffection and disaffiliation of the right-wing Cuban immigrant community, and from the failure of their own yearning to belong, to be wanted, to be embodied as the figure of their compelling <em>Cubanidad>. Against the hegemony of the invented collective politics of the sacrificing immigrants whose recognition of the queer side of being (of a being constituted by identity loss is yet to come, Lima suggests a spectral return—a personal and transnational reckoning of those whose lives the dream of freedom drowned.

    Full Text Available A compound named SD118-xanthocillin X (1 (C18H12N2O2, isolated from <em>Penicillium> <em>commune> in a deep-sea sediment sample, has been shown to inhibit the growth of several cancer cell lines <em>in vitroem>. In the present study, we employed a growth inhibition assay and apoptotic analysis to identify the biological effect and detailed mechanism of SD118-xanthocillin X (1 in human hepatocellular carcinoma (HepG2 cells. SD118-xanthocillin X (1 demonstrated a concentration-dependent inhibitory effect on the growth of HepG2 cells and caused slight cellular apoptosis and significantly induced autophagy. Autophagy was detected as early as 12 h by the conversion of microtubule-associated protein 1 light chain 3 (LC3-I to LC3-II, following cleavage and lipid addition to LC3-I. The pharmacological autophagy inhibitor 3-methyladenine largely attenuates the growth inhibition and autophagic effect of SD118-xanthocillin X (1 in HepG2 cells. Our data also indicated that the autophagic effect of SD118-xanthocillin X (1 occurs via the down-regulation of the MEK/ERK signaling pathway and the up-regulated class III PI3K/Beclin 1 signaling pathway.

    Full Text Available OBJETIVO: Identificar vantagens e desvantagens do uso de segmentos em relação ao sorteio feito a partir da lista completa de endereços, para o sorteio de domicílios em amostragem por conglomerados em múltiplos estágios em favelas. PROCEDIMENTOS METODOLÓGICOS: Estudo qualitativo realizado em quatro favelas sorteadas no Inquérito de Saúde do Município de São Paulo, SP, 2008, nas quais foram aplicadas as duas técnicas. Foram realizados grupos focais com pesquisadores de campo - "arroladores" e entrevistadores do inquérito. Os conteúdos das conversações foram analisados, agrupados em categorias e organizados em núcleos temáticos. ANÁLISE DOS RESULTADOS: A utilização de segmentos de domicílios foi associada a numerosas vantagens e poucas desvantagens. Entre as vantagens, constaram a rapidez e facilidade na elaboração do cadastro de endereços e na localização e identificação de domicílios na etapa de realização das entrevistas, maior segurança dos entrevistadores e da população, maior acesso aos entrevistados, maior estabilidade e maior cobertura do cadastro produzido, e menor ocorrência de erros na identificação dos domicílios sorteados. CONCLUSÕES: A construção de cadastro de domicílios por meio da criação de segmentos é vantajosa em relação à listagem completa de endereços, quando feita em favelas. Por ter se mostrado uma opção econômica e fácil de ser aplicada, constitui alternativa para a simplificação do processo de amostragem em áreas com as suas características de desorganização e adensamento de domicílios.

    Full Text Available Girinimbine, a carbazole alkaloid isolated from the stem bark of <em>Murraya koenigii em>was tested for the<em> in vitroem> anti-tumour promoting and antioxidant activities. Anti-tumour promoting activity was determined by assaying the capability of this compound to inhibit the expression of early antigen of Epstein-Barr virus (EA-EBV in Raji cells that was induced by the tumour promoter, phorbol 12-myristate 13-acetate. The concentration of this compound that gave an inhibition rate at fifty percent was 6.0 µg/mL and was not cytotoxic to the cells. Immunoblotting analysis of the expression of EA-EBV showed that girinimbine was able to suppress restricted early antigen (EA-R. However, diffused early antigen (EA-D was partially suppressed when used at 32.0 µg/mL. Girinimbine exhibited a very strong antioxidant activity as compared to a-tocopherol and was able to inhibit superoxide generation in the 12-<em>O>-tetradecanoylphorbol-13-acetate (TPA-induced differentiated premyelocytic HL-60 cells more than 95%, when treated with the compound at 5.3 and 26.3 µg/mL, respectively. However girinimbine failed to scavenge the stable diphenyl picryl hydrazyl (DPPH-free radical.

    Full Text Available CV_2116 is a small hypothetical protein of 82 amino acids from the Gram-negative coccobacillus <em>Chromobacterium violaceumem>. A PSI-BLAST search using the CV_2116 sequence as a query identified only one hit (E = 2e−07 corresponding to a hypothetical protein OR16_04617 from <em>Cupriavidus basilensisem> OR16, which failed to provide insight into the function of CV_2116. The <em>CV_2116em> gene was cloned into the p15TvLic expression plasmid, transformed into <em>E. coliem>, and 13C- and 15N-labeled NMR samples of CV_2116 were overexpressed in <em>E. coliem> and purified for structure determination using NMR spectroscopy. The resulting high-quality solution NMR structure of CV_2116 revealed a novel α + β fold containing two anti-parallel β -sheets in the <em>N>-terminal two-thirds of the protein and one α-helix in the <em>C>-terminal third of the protein. CV_2116 does not belong to any known protein sequence family and a Dali search indicated that no similar structures exist in the protein data bank. Although no function of CV_2116 could be derived from either sequence or structural similarity searches, the neighboring genes of <em>CV_2116em> encode various proteins annotated as similar to bacteriophage tail assembly proteins. Interestingly, <em>C. violaceumem> exhibits an extensive network of bacteriophage tail-like structures that likely result from lateral gene transfer by incorporation of viral DNA into its genome (prophages due to bacteriophage infection. Indeed, <em>C. violaceumem> has been shown to contain four prophage elements and <em>CV_2116em> resides in the fourth of these elements. Analysis of the putative operon in which CV_2116 resides indicates that CV_2116 might be a component of the bacteriophage tail-like assembly that occurs in <em>C. violaceumem>.

    Full Text Available Exposure to endogenous sex hormones has been reported as a risk factor for breast cancer. The <em>CYP11A1em> gene encodes the key enzyme that catalyzes the initial and rate-limiting step in steroid hormone synthesis. In this study, the associations between single nucleotide polymorphisms (SNPs in <em>CYP11A1em> and breast cancer susceptibility were examined. Six SNPs in <em>CYP11A1 em>were genotyped using the MassARRAY IPLEX platform in 530 breast cancer patients and 546 healthy controls. Association analyses based on a χ2 test and binary logistic regression were performed to determine the odds ratio (<em>OR> and 95% confidence interval (95% <em>CI> for each SNP. Two loci (rs2959008 and rs2279357 showed evidence of associations with breast cancer risk. The variant genotype C/T-C/C of rs2959008 was significantly associated with a decreased risk (age-adjusted<em> ORem>, 0.75; 95% <em>CI>, 0.58–0.96; <em>P em>= 0.023 compared with the wild-type TT. However, the homozygous TT variant of rs2279357 exhibited increased susceptibility to breast cancer (age-adjusted<em> ORem>, 1.44; 95% <em>CI>, 1.05–1.98; <em>P em>= 0.022. The locus rs2959003 also showed an appreciable effect, but no associations were observed for three other SNPs. Our results suggest that polymorphisms of <em>CYP11A1em> are related to breast cancer susceptibility in Han Chinese women of South China.

    Full Text Available A series of twenty-five novel salicylanilide <em>N>-alkylcarbamates were investigated as potential acetylcholinesterase inhibitors. The compounds were tested for their ability to inhibit acetylcholinesterase (AChE from electric eel (<em>Electrophorus electricusem> L.. Experimental lipophilicity was determined, and the structure-activity relationships are discussed. The mode of binding in the active site of AChE was investigated by molecular docking. All the discussed compounds expressed significantly higher AChE inhibitory activity than rivastigmine and slightly lower than galanthamine. Disubstitution by chlorine in C'(3,4 of the aniline ring and the optimal length of hexyl-undecyl alkyl chains in the carbamate moiety provided the most active AChE inhibitors. Monochlorination in C'(4 exhibited slightly more effective AChE inhibitors than in C'(3. Generally it can be stated that compounds with higher lipophilicity showed higher inhibition, and the activity of the compounds is strongly dependent on the length of the <em>N>-alkyl chain.

    Full Text Available Chronic bee paralysis virus (CBPV infection causes chronic paralysis and loss of workers in honey bee colonies around the world. Although CBPV shows a worldwide distribution, it had not been molecularly detected in Japan. Our investigation of <em>Apis melliferaem> and <em>Apis cerana japonicaem> colonies with RT-PCR has revealed CBPV infection in <em>A. melliferaem> but not <em>A. c. japonicaem> colonies in Japan. The prevalence of CBPV is low compared with that of other viruses: deformed wing virus (DWV, black queen cell virus (BQCV, Israel acute paralysis virus (IAPV, and sac brood virus (SBV, previously reported in Japan. Because of its low prevalence (5.6% in <em>A. melliferaem> colonies, the incidence of colony losses by CBPV infection must be sporadic in Japan. The presence of the (− strand RNA in dying workers suggests that CBPV infection and replication may contribute to their symptoms. Phylogenetic analysis demonstrates a geographic separation of Japanese isolates from European, Uruguayan, and mainland US isolates. The lack of major exchange of honey bees between Europe/mainland US and Japan for the recent 26 years (1985–2010 may have resulted in the geographic separation of Japanese CBPV isolates.

    2012-08-01

    Full Text Available The complete 15,413-bp mitochondrial genome (mitogenome of <em>Sesamia inferensem> (Walker (Lepidoptera: Noctuidae was sequenced and compared with those of four other noctuid moths. All of the mitogenomes analyzed displayed similar characteristics with respect to gene content, genome organization, nucleotide comparison, and codon usages. Twelve-one protein-coding genes (PCGs utilized the standard ATN, but the <em>cox1 em>gene used CGA as the initiation codon; <em>cox1em>, <em>cox2em>, and <em>nad4em> genes had the truncated termination codon T in the <em>S. inferens em>mitogenome. All of the tRNA genes had typical cloverleaf secondary structures except for <em>trnS1(AGNem>, in which the dihydrouridine (DHU arm did not form a stable stem-loop structure. Both the secondary structures of <em>rrnL> and <em>rrnS> genes inferred from the <em>S. inferens em>mitogenome closely resembled those of other noctuid moths. In the A+T-rich region, the conserved motif “ATAGA” followed by a long T-stretch was observed in all noctuid moths, but other specific tandem-repeat elements were more variable. Additionally, the <em>S. inferens em>mitogenome contained a potential stem-loop structure, a duplicated 17-bp repeat element, a decuplicated segment, and a microsatellite “(AT7”, without a poly-A element upstream of the<em> trnM em>in the A+T-rich region. Finally, the phylogenetic relationships were reconstructed based on amino acid sequences of mitochondrial 13 PCGs, which support the traditional morphologically based view of relationships within the Noctuidae.

    Full Text Available The Small hive beetle, <em>Aethina tumidaem>, is an invasive pest of honey bees. Indigenous to sub-Saharan Africa, it has now become established in North America and Australia. It represents a serious threat to European honey bees. Commercially available entomopathogenic agents were screened for their potential to control beetle larvae. Entomopathogenic fungi investigated had minimal impact. The nematodes <em>Steinernema> krausseiem> and <em>S. carpocapsaeem> provided excellent control with 100% mortality of larvae being obtained. Sequential applications of the nematodes following larvae entering sand to pupate also provided excellent control for up to 3 weeks. The information gained supports the development of contingency plans to deal with <em>A. tumidaem> should it occur in the UK, and is relevant to the management of Small hive beetle where it is already present.

    Full Text Available Uma das principais tendências verificadas nos últimos anos é o aumento da colaboração científica, caracterizada pela co-autoria. Muitos autores destacam a importância do tema e indicam o crescimento da co-autoria na produção acadêmica. Entretanto, em âmbito nacional, nenhum trabalho considerou a análise de co-autoria no campo da Administração. Com base nisso, este estudo, de caráter bibliométrico, analisou os artigos publicados em co-autoria nos anais dos congressos promovidos pela ANPAD no período entre 2001 e 2010, perfazendo 12 eventos: 10 Encontros da ANPAD (EnANPAD e 2 Encontros de Ensino e Pesquisa em Administração e Contabilidade (EnEPQ. Ao total foram investigados 778 trabalhos. De uma forma geral, nota-se que grande parte dos trabalhos conduzidos em Administração no Brasil, na última década, utiliza a co-autoria. Quanto ao formato dos artigos, observa-se que a co-autoria prevalece nos estudos empíricos, enquanto os estudos teóricos são desenvolvidos, em sua maioria, por um único autor. No caso dos trabalhos teóricos, elaborados em co-autoria, nota-se, em média, um número menor de autores do que em trabalhos empíricos. Dentre os empíricos realizados em co-autoria, também há diferenças significativas, sendo que os trabalhos quantitativos apresentaram uma média de autores superior a dos artigos qualitativos. Também foi realizada uma análise da rede formada pelas 197 IES identificadas, fazendo considerações sobre a sua densidade, distância geodésica média, centralização e proximidade entre os elos. Acrescido a estas análises, discussões e considerações a respeito da co-autoria em Administração também são apresentadas no artigo. Sugestões de pesquisas futuras são propostas.

    Full Text Available Acid lipase belongs to a family of enzymes that is mainly present in lysosomes of different organs and the stomach. It is characterized by its capacity to withstand acidic conditions while maintaining high lipolytic activity. We cloned for the first time the full coding sequence of camel’s lysosomal acid lipase, <em>cLIPA em>using RT-PCR technique (Genbank accession numbers JF803951 and AEG75815, for the nucleotide and aminoacid sequences respectively. The cDNA sequencing revealed an open reading frame of 1,197 nucleotides that encodes a protein of 399 aminoacids which was similar to that from<em> em>other related mammalian species. Bioinformatic analysis was used to determine the aminoacid sequence, 3D structure and phylogeny of cLIPA. Bioinformatics analysis suggested the molecular weight of the translated protein to be 45.57 kDa, which could be decreased to 43.16 kDa after the removal of a signal peptide comprising the first 21 aminoacids. The deduced <em>cLIPA em>sequences exhibited high identity with <em>Equus caballus em>(86%, <em>Numascus leucogenysem> (85%, <em>Homo sapiensem> (84%,<em> Sus scrofaem> (84%, <em>Bos taurus em>(82% and <em>Ovis aries em>(81%. cLIPA shows high aminoacid sequence identity with human and dog-gastric lipases (58%, and 59% respectively which makes it relevant to build a 3D structure model for cLIPA. The comparison confirms the presence of the catalytic triad and the oxyanion hole in cLIPA. Phylogenetic analysis revealed that camel <em>cLIPA em>is grouped with monkey, human, pig, cow and goat. The level of expression of <em>cLIPA em>in five camel tissues was examined using Real Time-PCR. The highest level of <em>cLIPA em>transcript was found in the camel testis (162%, followed by spleen (129%, liver (100%, kidney (20.5% and lung (17.4%.

    Full Text Available <em>Mytilus coruscusem> (family Mytilidae is one of the most important marine shellfish species in Korea. During the past few decades, this species has become endangered due to the loss of habitats and overfishing. Despite this species’ importance, information on its genetic background is scarce. In this study, we developed microsatellite markers for <em>M.> coruscusem> using next-generation sequencing. A total of 263,900 raw reads were obtained from a quarter-plate run on the 454 GS-FLX titanium platform, and 176,327 unique sequences were generated with an average length of 381 bp; 2569 (1.45% sequences contained a minimum of five di- to tetra-nucleotide repeat motifs. Of the 51 loci screened, 46 were amplified successfully, and 22 were polymorphic among 30 individuals, with seven of trinucleotide repeats and three of tetranucleotide repeats. All loci exhibited high genetic variability, with an average of 17.32 alleles per locus, and the mean observed and expected heterozygosities were 0.67 and 0.90, respectively. In addition, cross-amplification was tested for all 22 loci in another congener species, <em>M.> <em>galloprovincialis.> None of the primer pairs resulted in effective amplification, which might be due to their high mutation rates. Our work demonstrated the utility of next-generation 454 sequencing as a method for the rapid and cost-effective identification of microsatellites. The high degree of polymorphism exhibited by the 22 newly developed microsatellites will be useful in future conservation genetic studies of this species.

    Full Text Available High permittivity (<em>k> gate dielectric films are widely studied to substitute SiO2 as gate oxides to suppress the unacceptable gate leakage current when the traditional SiO2 gate oxide becomes ultrathin. For high-<em>k> gate oxides, several material properties are dominantly important. The first one, undoubtedly, is permittivity. It has been well studied by many groups in terms of how to obtain a higher permittivity for popular high-<em>k> oxides, like HfO2 and La2O3. The second one is crystallization behavior. Although it’s still under the debate whether an amorphous film is definitely better than ploy-crystallized oxide film as a gate oxide upon considering the crystal boundaries induced leakage current, the crystallization behavior should be well understood for a high-<em>k> gate oxide because it could also, to some degree, determine the permittivity of the high-<em>k> oxide. Finally, some high-<em>k> gate oxides, especially rare earth oxides (like La2O3, are not stable in air and very hygroscopic, forming hydroxide. This topic has been well investigated in over the years and significant progresses have been achieved. In this paper, I will intensively review the most recent progresses of the experimental and theoretical studies for preparing higher-<em>k> and more stable, in terms of hygroscopic tolerance and crystallization behavior, Hf- and La-based ternary high-<em>k> gate oxides.

    Full Text Available The landrace strains of <em>Momordica charantia em>are widely cultivated vegetables throughout the tropics and subtropics, but not in Taiwan, a continental island in Southeast Asia, until a few hundred years ago. In contrast, the related wild populations with smaller fruit sizes are native to Taiwan. Because of the introduction of cultivars for agricultural purposes, these two accessions currently exhibit a sympatric or parapatric distribution in Taiwan. In this study, the cultivars<em> em>and wild samples from Taiwan, India, and Korea<em> em>were collected for testing of their hybridization and evolutionary patterns. The cpDNA marker showed a clear distinction between accessions of cultivars and wild populations of Taiwan and a long divergence time. In contrast, an analysis of eight selectively neutral nuclear microsatellite loci did not reveal a difference between the genetic structures of these two accessions. A relatively short divergence time and frequent but asymmetric gene flows were estimated based on the isolation-with-migration model. Historical and current introgression from cultivars to wild populations of Taiwan was also inferred using MIGRATE-n and BayesAss analyses. Our results showed that these two accessions shared abundant common ancestral polymorphisms, and the timing of the divergence and colonization of the Taiwanese wild populations is consistent with the geohistory of the Taiwan Strait land bridge of the Last Glacial Maximum (LGM. Long-term and recurrent introgression between accessions indicated the asymmetric capacity to receive foreign genes from other accessions. The modern introduction of cultivars of <em>M>. <em>charantia> during the colonization of Taiwan by the Han Chinese ethnic group enhanced the rate of gene replacement in the native populations and resulted in the loss of native genes.

    Full Text Available INTRODUÇÃO: A pulpotomia em dentes decíduos é uma técnica conservadora de terapia pulpar amplamente utilizada em Odontopediatria, sendo de fundamental importância para evitar a perda prematura desses dentes, quer seja por alterações provocadas pela cárie dentária ou traumatismo dentário. Apesar de ser uma técnica estudada há muitos anos, causa muitas controvérsias e discussões, principalmente em termos de biocompatibilidade dos medicamentos empregados e pelas dificuldades e falhas no diagnóstico da condição pulpar. OBJETIVO: Por meio de uma revisão sistemática da literatura, no período compreendido entre 2000 e 2011, e com enfoque em estudos clínicos randomizados, revisões sistemáticas e meta-análises, este trabalho teve como objetivo discutir, com base em evidências científicas, alternativas para o tratamento de pulpotomia em dentes decíduos humanos. CONCLUSÃO: As evidências científicas fidedignas com o uso de materiais capeadores pulpares e as técnicas de Eletrocirurgia e Laser de Baixa Potência foram escassas. Desta forma, sugere-se a realização de estudos complementares bem delineados estatisticamente para maiores esclarecimentos. As informações geradas em tais experimentos poderão contribuir para um melhor entendimento dos mecanismos da terapia pulpar, podendo gerar o desenvolvimento de protocolos com novas formas terapêuticas, que visam a melhorar a terapia pulpar em dentes decíduos.

Even taking into account the inhomogeneity of the fossil specimens and the deformation suffered by the skulls of <em>H. pentlandiem> from Cannita cave, the examination confirms on one hand the stronger affinity of the sicilian species with the living <em>H. amphibiusem> and from the other hand the peculiarities that characterize this form with respect to the european continental ones. A comparative examination of the biometric characters of the skull of these latter species confirms the greater distance of <em>H. antiquusem> Desmarest from the living species. It is stressed how the relations between the less bulky Pleistocene species (<em>Hippopotamus incognitusem> Faure with <em>H. antiquusem> and with the living <em>H. amphibiusem> have not yet been completely clarified, owing both to the scantiness of the documentation and to the strong variability observed in the biometric characters of the few known skulls. It is noted how, in any case, this fossil form appears more similar to the living <em>H. amphibiusem>. For the moment its distinction at a specific level is accepted, even if with reservation, taking into account also the distinctive elements recognized in the post-cranial skeleton (FAURE, 1985, not examined here.

    A descriptive study of breast and cervix cancer was performed in patients who have received treatment linear accelerator, during the period 2000 - 2001 in the Centro Medico de Radioterapia Irazu. The survival of the patients was assessed to five years (2006). One proposal called database is the product of analysis performed and consistent with the objectives set. The idea to develop the database of these features in the medical center, arises because the Centre was at that time with the only linear accelerator in the country and also all the necessary information of patients was easily accessible. A population of 438 records, with a common pathology was analyzed under the following variables: type of cancer, identification of anatomic region, province, age, sex, type of radiation, number of sessions, referral hospital, physician, physician referral. This work is relevant, because breast and cervical cancers have been a major cause of mortality, ranked among the five most common malignancies in women. From there to have adequate information systems, has led policy makers and health professionals to have a better outlook for their level of management. (author) [es

    Full Text Available O meloeiro (Cucumis melo L. é uma hortaliça de alto valor econômico. A emissão de nós é um componente importante em modelos matemáticos de simulação do crescimento e desenvolvimento de culturas de hábito de crescimento decumbente como o meloeiro e outras cucurbitáceas. A emissão de nós pode ser calculada utilizando-se o conceito do plastocrono, que é o intervalo de tempo entre o aparecimento de nós sucessivos em uma haste de dicotiledôneas. Quando a soma térmica é usada como medida de tempo fisiológico em plantas, o plastocrono tem como unidades degreesC dia nó-1. Estudos anteriores mostraram que o plastocrono em meloeiro varia com o genótipo e a época de cultivo. Este trabalho teve por objetivo estimar o plastocrono em meloeiro transplantado em diferentes épocas de cultivo no interior de estufa plástica. Foram realizadas 12 épocas de semeadura e transplante no interior de uma estufa plástica de 10m X 25m, coberta com polietileno transparente de baixa densidade, localizada no Campo Experimental do Departamento de Fitotecnia da Universidade Federal de Santa Maria, RS. O híbrido utilizado foi o HY-MARK (grupo Cantaloupe. Em 12 plantas etiquetadas por época de transplante, contou-se o número de nós visíveis (NN na haste principal da planta duas vezes por semana. A soma térmica diária (STd, degreesC dia foi calculada levando-se em conta as temperaturas cardinais de aparecimento de nós em meloeiro (10, 34 e 45degreesC. A soma térmica acumulada (STa, degreesC dia, a partir da data de transplante das plântulas, foi calculada somando-se a STd. O plastocrono foi calculado como sendo o inverso do coeficiente angular da regressão linear entre NN e STa para cada época. O plastocrono calculado variou entre as épocas de cultivo de 13,4 a 21,8degreesC dia nó-1, com um valor médio de 18,6 (?2,3degreesC dia nó-1. Esta diferença de plastocrono entre as épocas de cultivo pode representar vários dias do calendário civil

Sono stati percorsi 61 km ed è stata campionata un'area di 12 ha. Per ogni gruppo di escrementi (1583 per il cervo e 946 per il capriolo sono state rilevate l'altitudine, la pendenza, l'esposizione e il tipo di vegetazione. È stato assunto che tutti gli habitat fossero ugualmente disponibili ed accessibili e che le disponibilita fossero conosciute (Alldredge <em>et al.em>, 1998. I dati raccolti sono stati elaborati applicando il test del Χ², la statistica di Bonferroni (Neu <em>et al.em>, 1974 e l'indice Jacobs (Jacobs, 1974. Il cervo ha selezionato aree comprese tra 1300 e 1500 m s.l.m.

    Full Text Available The <em>Parmenides> is known as the dialogue in which Plato makes a criticism of his theory of forms. Through paradoxes, the character Parmenides criticizes the theory of forms presented by Socrates in the dialogue, targeting the relation they have with sensibles and with each other, call for participation, and the discoursive consequences of this relation. I present a reading of the Parmenides that suggests that the self-criticism points out inconsistencies in the Platonic theory of participation as it is presented in the Parmenides, and that will be corrected later in the Sophist.O <em>Parmênides> é conhecido como o diálogo em que Platão faz uma crítica de sua teoria das formas.

    Full Text Available In capacitance-voltage (C-V measurements, frequency dispersion in high-<em>k> dielectrics is often observed. The frequency dependence of the dielectric constant (<em>k>-value, that is the intrinsic frequency dispersion, could not be assessed before suppressing the effects of extrinsic frequency dispersion, such as the effects of the lossy interfacial layer (between the high-<em>k> thin film and silicon substrate and the parasitic effects. The effect of the lossy interfacial layer on frequency dispersion was investigated and modeled based on a dual frequency technique. The significance of parasitic effects (including series resistance and the back metal contact of the metal-oxide-semiconductor (MOS capacitor on frequency dispersion was also studied. The effect of surface roughness on frequency dispersion is also discussed. After taking extrinsic frequency dispersion into account, the relaxation behavior can be modeled using the Curie-von Schweidler (CS law, the Kohlrausch-Williams-Watts (KWW relationship and the Havriliak-Negami (HN relationship. Dielectric relaxation mechanisms are also discussed.

  15. <em>In Situem> Fabrication of AlN Coating by Reactive Plasma Spraying of Al/AlN Powder

    Full Text Available Reactive plasma spraying is a promising technology for the <em>in situem> formation of aluminum nitride (AlN coatings. Recently, it became possible to fabricate cubic-AlN-(<em>c>-AlN based coatings through reactive plasma spraying of Al powder in an ambient atmosphere. However, it was difficult to fabricate a coating with high AlN content and suitable thickness due to the coalescence of the Al particles. In this study, the influence of using AlN additive (<em>h>-AlN to increase the AlN content of the coating and improve the reaction process was investigated. The simple mixing of Al and AlN powders was not suitable for fabricating AlN coatings through reactive plasma spraying. However, it was possible to prepare a homogenously mixed, agglomerated and dispersed Al/AlN mixture (which enabled in-flight interaction between the powder and the surrounding plasma by wet-mixing in a planetary mill. Increasing the AlN content in the mixture prevented coalescence and increased the nitride content gradually. Using 30 to 40 wt% AlN was sufficient to fabricate a thick (more than 200 µm AlN coating with high hardness (approximately 1000 Hv. The AlN additive prevented the coalescence of Al metal and enhanced post-deposition nitriding through N2 plasma irradiation by allowing the nitriding species in the plasma to impinge on a larger Al surface area. Using AlN as a feedstock additive was found to be a suitable method for fabricating AlN coatings by reactive plasma spraying. Moreover, the fabricated coatings consist of hexagonal (<em>h>-AlN, <em>c>-AlN (rock-salt and zinc-blend phases and certain oxides: aluminum oxynitride (Al5O6N, cubic sphalerite Al23O27N5 (ALON and Al2O3. The zinc-blend <em>c>-AlN and ALON phases were attributed to the transformation of the <em>h>-AlN feedstock during the reactive plasma spraying. Thus, the zinc-blend<em> cem

A hipertensão arterial foi o diagnóstico mais frequente em 73% dos pacientes, com predominância em mulheres (51,4%. O cisto hepático foi a manifestação extrarrenal mais frequente nos homens (60,0%. Foram a óbito 10,4% dos pacientes que faziam uso de hemodiálise, sendo 60% de homens. A classe de droga anti-hipertensiva mais utilizada foi a que atua no sistema renina-angiotensina, com maior frequência de uso nas mulheres (53,3%. A ureia pós-diálise foi significativamente maior em homens. Conclusão: A prevalência da doença é baixa entre pacientes em hemodiálise no sul do Brasil. As diferenças observadas entre os gêneros, com exceção da ureia pós, não foram significantes. Os dados encontrados são diferentes dos reportados na América do Norte e Europa.

    Full Text Available Muitas pesquisas conferem maior peso na alta declividade do terreno como fator decisivo no processo hidro-erosivo. Porém, foi avaliado que baixas declividades (~4º já são suficientes para se iniciar o escoamento superficial. A pesquisa teve como objetivo fazer uma caracterização físico-química de solo degradado, monitorar o seu potencial matricial e o processo de formação de escoamento em uma sub-bacia do rio Maranduba - Ubatuba/SP, em encosta com baixa declividade. O trabalho se baseou na instalação de parcelas de erosão em solo sem cobertura vegetal para analisar as perdas de solo e água, bem como as propriedades físicas e químicas do solo (Porosidade, textura, densidade, pH e matéria orgânica. As parcelas se localizam na parte intermediária de um morrote com encosta retilínea, esse sofreu alteração em sua morfologia original por meio de um corte de encosta (UTM: 0474211/7395934.  O solo do local é um Latossolo que apresenta o horizonte B exposto. Cerca de 6,9 t/ha de solo foram perdidos durante o monitoramento (01 agosto 2013-20 dezembro 2014 e mais de 5.354,7 m3 de água foram escoados superficialmente. Salienta-se a fragilidade dos ambientes degradados de baixa declividade frente às altas taxas de perdas de solo e água, que, no período de 17 meses de monitoramento e com chuvas dentro da normalidade para o município, totalizaram 63 dias com ocorrências de escoamento, em solos que tendem à saturação por períodos prolongados. Portanto, o transporte das partículas de solo superficialmente está atrelado à baixa drenagem do terreno e à perda da resistência do solo, corroborando em períodos longos de umidade antecedente, sendo este um dos fatores decisivos para se iniciar o escoamento superficial.

  13. A Intervenção em Psicologia em uma Universidade na Amazônia Sul Ocidental

    Full Text Available Resumo: O objetivo desse relato é descrever uma experiência profissional em Psicologia vivenciada em uma universidade pública, destacando questões como o alcance e a qualidade da intervenção em Psicologia nas políticas públicas de educação superior. Diante da demanda de realizar o trabalho em Psicologia com atendimentos individuais de tratamento, a estratégia foi apresentar um projeto de trabalho no qual a ação principal seria a promoção à saúde, ao mesmo tempo que os relatórios das atividades desenvolvidas eram entregues sistematicamente, demonstrando, a partir de resultados como: níveis baixos de procura e níveis altos de evasão e de custo, que a proposta da gestão não seria a melhor estratégia. As atividades de promoção e prevenção em saúde, com trabalhos em grupo substancialmente, precisariam ser objetivo principal da intervenção em Psicologia em uma universidade. Uma política pública que quer intervir apenas nos sintomas e não nas causas destes, apresenta-se como apoio ao desmonte das universidades públicas. As ações propostas para cuidar da saúde dos servidores e servidoras e estudantes se tornam uma intervenção sem impacto significativo na instituição e que não contribui para a afirmação da universidade gratuita, de qualidade, laica e socialmente referenciada, estando, assim, corroborando para o seu desmonte e, em curto prazo, possibilitar a privatização no lugar de efetivamente contribuir para a construção de uma educação de qualidade.

    Full Text Available Esse trabalho tem como objetivo avaliar o incremento em diâmetro da espécie Swietenia machophylla em um sistema Agroflorestal. Em uma área de 1 ha foram alocadas 5 parcelas de 12 x 24 m. As medições foram realizadas em  três ocasiões, sendo: Janeiro de 2014, Janeiro de 2015 e Julho de 2015. Para construção dos histogramas de frequência foram testados os métodos de Sturges e “empírico”. Em um segundo plano histogramas de crescimento foram elaborados tendo em vista a visualização dos diâmetros de cada indivíduo para análise do incremento em diâmetro. O melhor resultado para construção dos histogramas foi o método “empírico”, pois apresentou menor erro. O incremento no DAP médio foi de 0,58 cm entre as três medições, no primeiro período o incremento em diâmetro foi de 11,32, no segundo 11,76 cm e no último 11,90 cm.

A análise se baseia no trabalho desenvolvido por Sena Pereira (2015 que aborda a colocação de clíticos nesse contexto na escrita brasileira dos séculos XIX e XX. Nossa proposta é que preposições que ocupam o núcleo de CP motivam mudanças nos valores atribuídos aos traços-phi e aos traços-V fortes nas categorias funcionais COMP, Tempo e Pessoa no PB. Defendemos que em tal configuração a próclise em PB é derivada do movimento do verbo para a categoria funcional Tempo em que há a associação de traços [+V] e traços [+AGR].

    Full Text Available Neste estudo, objetivou-se descrever a prevalência de "suspeitos" de transtornos mentais comuns (TMC em trabalhadores de enfermagem em um hospital geral, no estado da Bahia. Realizou-se um estudo epidemiológico, de corte transversal, com 309 profissionais de enfermagem, que trabalhavam em atividades assistenciais em um hospital de grande porte. Os profissionais de enfermagem referiram sobrecarga de trabalho e baixa remuneração. As queixas de saúde mais frequentes estavam relacionadas à postura corporal e a saúde mental. A prevalência geral de "suspeitos" de TMC foi de 35,0%. Em relação aos aspectos psicossociais do trabalho, relataram uma alta demanda psicológica e baixo controle sobre as atividades laborais. Os resultados obtidos apontam que as condições de trabalho e saúde observadas, não são adequadas para a efetiva realização do trabalho de enfermagem no hospital estudado.

    Full Text Available Eicosapentaenoic and docosahexaenoic acids have been reported to have a variety of beneficial effects on cardiovascular disease risk factors. However, a large inter-individual variability in the plasma lipid response to an omega-3 (<em>n>-3 polyunsaturated fatty acid (PUFA supplementation is observed in different studies. Genetic variations may influence plasma lipid responsiveness. The aim of the present study was to examine the effects of a supplementation with <em>n>-3 PUFA on the plasma lipid profile in relation to the presence of single-nucleotide polymorphisms (SNPs in the fatty acid desaturase (<em>FADS> gene cluster. A total of 208 subjects from Quebec City area were supplemented with 3 g/day of <em>n>-3 PUFA, during six weeks. In a statistical model including the effect of the genotype, the supplementation and the genotype by supplementation interaction, SNP rs174546 was significantly associated (<em>p> = 0.02 with plasma triglyceride (TG levels, pre- and post-supplementation. The <em>n>-3 supplementation had an independent effect on plasma TG levels and no significant genotype by supplementation interaction effects were observed. In summary, our data support the notion that the <em>FADS em>gene cluster is a major determinant of plasma TG levels. SNP rs174546 may be an important SNP associated with plasma TG levels and <em>FADS>1 gene expression independently of a nutritional intervention with <em>n>-3 PUFA.

    Full Text Available O diagnóstico da úlcera gastroesofágica (UGE é fundamental para que se tente a recuperação dos afetados, entretanto há grande dificuldade na sua realização de forma precisa. Modernos endoscópios são ferramentas importantes nesse sentido e podem ser usados para determinar em que fase da criação a ulceração ocorre. A bactéria Helicobacter tem sido associada à UGE e gerado perdas econômicas. Tendo em vista que poucos trabalhos têm sido realizados para identificação do problema precocemente, este estudo teve como objetivo detectar as lesões relacionando-as, ou não, com a bactéria Helicobacter spp., mediante análises macroscópica e histopatológica de amostras colhidas por meio da gastroscopia. Foram utilizados 20 animais de ambos os sexos, pesando entre 22 e 26kg e com 65 dias de idade. O aparelho utilizado foi um gastrovideoscópio da marca Karl Storz, modelo 1380NKS. Foram colhidas amostras das regiões anatômicas aglandular (quadrilátero esofágico e glandular (cárdica, fúndica e pilórica para o teste ultrarrápido da urease e para as avaliações histopatológicas e imuno-histoquímicas. Onze animais apresentaram lesões na região aglandular à endoscopia, e microscopicamente 15 animais apresentaram paraqueratose. Em 18 animais, foram observadas alterações em pelo menos uma das três regiões glandulares. As lesões foram maiores na região cárdica, seguida da antral e da fúndica. Em relação ao teste ultrarrápido da urease, sete animais foram negativos nas quatro regiões, e 13 positivos em pelo menos uma delas. Em relação à imuno-histoquímica (IHQ, 10 animais foram negativos em todas as regiões e 10 foram positivos em pelo menos uma delas. Os achados pré-ulcerativos não demonstraram relação com o Helicobacter spp., que apresenta caráter saprofítico e oportunista confirmado pela sua imunomarcação em áreas sem lesão.

    2014-01-01

    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.

O experimento foi realizado em Dourados (MS, Brasil, em delineamento de blocos casualizados, com os tratamentos dispostos em esquema de parcelas subdivididas e quatro repetições. As parcelas foram constituídas pelos adubos verdes: ervilhaca peluda (Vicia villosa, crotalária (Crotalaria juncea, mucuna anã (Mucuna deeringiana, lablabe (Dolichus lablab e um tratamento- testemunha, em pousio. Nas subparcelas foram testadas quatro doses de N em cobertura: 0 (zero, 45, 90 e 135 kg ha-1, utilizando a uréia como fonte de N. Foram realizadas avaliações de massa seca das coberturas vegetais, teores de N nos tecidos da parte área dos adubos verdes e nas folhas de trigo, altura de plantas, número de perfilhos produtivos por planta, tamanho da espiga, número de grãos por espiga, massa de mil grãos, peso hectolitro e produtividade. Concluiu-se que maiores produtividades na cultura do trigo são obtidas quando é cultivado após crotalária e ervilhaca peluda e que a resposta do trigo à aplicação de N mineral em adubação de cobertura varia em função da cultura antecessora.

    Full Text Available Em meio às normas emitidas pelo International Accounting Standards Board (IASB e pelo Financial Accounting Standards Board (FASB, o presente estudo tem como objetivo analisar quais as principais normas em que as características que as conduzem a ser mais baseadas em princípios ou em regras são mais evidentes. Para atingir esse objetivo, este trabalho compara as principais normas emitidas pelo IASB e pelo FASB. Esses dois órgãos normatizadores foram escolhidos devido ao fato de que a literatura corrente considera que as normas emitidas pelo IASB e pelo FASB são, respectivamente, baseadas em princípios e em regras. Este trabalho, fruto de uma pesquisa documental e uma análise de conteúdo, revela que as normas do FASB, apesar de terem uma estrutura conceitual como base, possuem diversas especificidades que permitem que sejam consideradas como baseadas em regras. Dentre as normas estudadas, a característica do detalhamento presente nas normas de receitas emitidas pelo FASB e a presença de bright lines ou “limites” percentuais nas normas de relatórios por segmento, provisões e arrendamento mercantil conduzem a se classificar como baseadas em regras. Já as normas do IASB, por serem menos detalhadas e, praticamente, não possuírem bright lines, deixam espaço para maior julgamento profissional, ou seja, apresentam mais características de normas baseadas em princípios.

Esta investigación se realizó en la granja Montelindo (Universidad de Caldas, a 1.050 msnm, temperatura media anual 22,8 °C, precipitación anual 2.200 mm y humedad relativa 76%. Se sembraron cormos de Dominico Hartón, África, FHIA-20 y FHIA-21, en diseño de bloques al azar con cuatro repeticiones y 10 plantas por repetición. Desde siembra hasta cosecha se registraron incidencia, severidad, número de esporas y elementos climáticos. Se definieron cinco estados fenológicos: brotación y emergencia, plántula, prefloración, floración, y llenado del racimo y madurez fisiológica. Las sigatokas se presentaron desde la etapa de plántula hasta madurez fisiológica; fue más agresiva la sigatoka negra en el área de estudio. La mayor población de conidias en D. Hartón y África se presentó en etapas de prefloración y llenado del racimo; en los híbridos FHIA-20 y FHIA-21 coincidió con la etapa de floración. Incrementos graduales de temperatura, precipitación intensa intercalada con periodos secos y aumento en la humedad foliar favorecieron la incidencia y severidad de las sigatokas.

    To identify errors in forensic reports and to describe the characteristics of traumatic medico-legal cases presenting to the emergency department (ED) at a tertiary care hospital. This study is a retrospective cross-sectional study. The study includes cases resulting in a forensic report among all traumatic patients presenting to the ED of Adiyaman University Training and Research Hospital, Adiyaman, Turkey during a 1-year period. We recorded the demographic characteristics of all the cases, time of presentation to the ED, traumatic characteristics of medico-legal cases, forms of suicide attempt, suspected poisonous substance exposure, the result of follow-up and the type of forensic report. A total of 4300 traumatic medico-legal cases were included in the study and 72% of these cases were male. Traumatic medico-legal cases occurred at the greatest frequency in July (10.1%) and 28.9% of all cases occurred in summer. The most frequent causes of traumatic medico-legal cases in the ED were traffic accidents (43.4%), violent crime (30.5%), and suicide attempt (7.2%). The most common method of attempted suicide was drug intake (86.4%). 12.3% of traumatic medico-legal cases were hospitalized and 24.2% of those hospitalized were admitted to the orthopedics service. The most common error in forensic reports was the incomplete recording of the patient's "cooperation" status (82.7%). Additionally, external traumatic lesions were not defined in 62.4% of forensic reports. The majority of traumatic medico-legal cases were male age 18-44 years, the most common source of trauma was traffic accidents and in the summer months. When writing a forensic report, emergency physicians made mistakes in noting physical examination findings and identifying external traumatic lesions. Physicians should make sure that the traumatic medico-legal patients they treat have adequate documentation for reference during legal proceedings.

Rodentia are dominant (86.93% of the biomass; <em>Microtus saviiem> is of particular importance and represents 61.06% of the total biomass and was found in 60.42% of the pellets found. The second most frequently hunted species is the <em>Apodemus> sp.: 24.06% of the biomass, 37.08% of the frequency. The other mammals preyed on (<em>Suncus etruscuem>s, <em>Crocidura> sp., <em>Pipistrellus> sp., <em>Vespertilius> sp., <em>Rattus> sp., <em>Moscardinus avellanariusem> are of little importance: 1.27% of the biomass. The owls preyed upon 9 of the 11 species of mammals present (the <em>Talpa> sp. and the <em>Mus domesticusem> are absent. Affinity among different periods, estimated through Sorensen's Index, was found to be medium-high (0.67-0.72. The data analysis confirms the stenophagy of the Long-eared Owl, in this area that is characterised by extensive cereal cultivation and few shrubs and trees. In comparison with other Italian localities, a greater number of preyed species was recorded (8 mammals, 9 birds, 1 insect. Roost owls preyed mainly upon <em>Chiroptera> (0.36% compared with 0.1-0.2. <em>Myotis capacciniiem> and <em>Pipistrellus saviiem> were also found in the diet of the Long-eared Owl for the first time in Italy.

    The medico-legal risk specifically associated with the practice of ambulatory surgery is still not well studied. SHAM insurances are the biggest French provider of medical liability insurances. The study of the insurance claims provided by this insurer is therefore a relevant source of data on the complications related to ambulatory surgery. The aim of this study was to compare the claim rate related to ambulatory surgery with non-ambulatory surgery. We did a retrospective study on insurance claims provided by SHAM insurances between 2007 and 2011 to compare the claim rate related to ambulatory surgery with non-ambulatory surgery. We searched the files in the SHAM database, and then analyzed them. On the study period, out of a total of 29565 registered claims, 467 (1.6%) originated from ambulatory surgery. On the total of 29,098 registered claims for non-ambulatory surgery, 2151 (7.4%) led to a condemnation whereas the rate was 7% (33 out of 467 claims) for ambulatory surgery. The condemnations linked to ambulatory surgery amounted to 1.5% of the total (33 out of 2184), for a cost of 1.7 M€ (versus 400,3 M€ for non-ambulatory surgery). The average cost of a compensation is therefore 50,500 € for ambulatory surgery and 186,000 € for non-ambulatory surgery. The medical specialties concerned are primarily ophthalmology, abdominal and orthopedics surgery. The main identified causes were medical errors (n=16) and nosocomial infections (n=13). The claim rate in ambulatory surgery is proportionally less frequent with compensations three times less and were related to the most frequent type of surgery done in ambulatory settings. These data should help strengthen quality approach in ambulatory surgery. Copyright © 2014 Société française d’anesthésie et de réanimation (Sfar). Published by Elsevier SAS. All rights reserved.

    Full Text Available Durante os últimos anos, o incremento de toxinfecções alimentares em humanos pela ingestão de produtos avícolas contaminados com bactérias, sugeriu que produtos oriundos de aves portadoras dessas bactérias podem veiculá-las ao consumidor, provocando doenças entéricas em humanos. Essas observações e a restrição, por parte do mercado consumidor, ao uso de antimicrobianos na produção animal, aumentaram o interesse mundial pelos probióticos e, conseqüentemente, o número de pesquisas realizadas. Esta revisão mostra os avanços e a situação em que se encontram os probióticos em relação à indústria avícola.

  17. A infância em Piaget e o infantil em Freud: temporalidades e moralidades em questão

    Directory of Open Access Journals (Sweden)

    Maria Regina Maciel

    Full Text Available Resumo O presente artigo propõe uma abordagem comparativa entre as noções de infância em Jean Piaget e de infantil em Sigmund Freud, tomando como conceitos básicos a noção de tempo e de moral em ambos os autores. Sustenta-se ser possível afirmar, a partir de uma leitura da epistemologia genética, que a infância vai-se transformando à medida que agimos e conhecemos de acordo com estruturas cognitivas operatórias. No entanto, segundo a psicanálise, é possível nos remeter ao infantil, presente também na vida adulta. O infantil escapa à racionalidade que subjaz àquela noção de estrutura piagetiana. A permanência do infantil é fonte das experiências criativas e da instauração de um movimento permanente de subjetivação.

    Full Text Available As favelas do Rio de Janeiro têm sido alvo de intensa visitação turística desde os anos 2000. Se antes esse turismo se concentrava na Rocinha, paradigmática favela turística, hoje expande-se para outras favelas da cidade, e tal expansão vem acompanhada da ampliação do debate sobre esse tipo específico de turismo. Neste artigo, analiso três eventos de disputa em torno do tema “turismo em favelas”, ocorridos entre 2014 e 2015: a série de debates “Fala Vidigal!”; o I Congresso de Turismo de Base Comunitária da Rocinha; e o Grupo de Trabalho (GT sobre Turismo em Favelas na Câmara dos Vereadores do Rio de Janeiro. Os três eventos se apresentaram como interessantes cenários para observação participante e análise dos discursos sobre turismo em favela, tanto por parte da academia, como também por parte de empreendedores externos, empreendedores locais, moradores de favelas e órgãos públicos.

  19. A emissão em 8mm e as bandas de Merrill-Sanford em estrelas carbonadas

    2003-08-01

    Estrelas carbonadas possuem bandas moleculares em absorção no visível e, no infravermelho (IR) as principais características espectrais se devem a emissão de grãos. Recentemente foi detectada a presença de bandas de SiC2 (Merrill-Sanford, MS) em emissão sendo atribuída à presença de um disco rico em poeira. Neste trabalho analisamos uma amostra de 14 estrelas carbonadas, observadas no telescópio de 1.52 m do ESO em 4 regiões espectrais diferentes, a fim de detectar as bandas de MS em emissão. Nossa amostra é composta de estrelas que apresentam além da emissão em 11.3 mm, outra em 8 mm. Esta última emissão, não usual nestes objetos, tem sido atribuída ou a moléculas de C2H2, ou a um composto sólido ainda indefinido. A detecção de emissões de MS e aquelas no IR, simultaneamente, revelaria um cenário mais complexo que o habitualmente esperado para os ventos destes objetos. No entanto como primeiro resultado, verificamos que as bandas de Merrill-Sanford encontram-se em absorção, não revelando nenhuma conexão com a emissão a 8 mm. Assim, temos duas hipóteses: (a) a emissão a 8 mm se deve à molécula C2H2 ou (b) essa emissão é resultado da emissão térmica de grãos. Testamos a segunda hipótese modelando a amostra com grãos não-homogêneos de SiC e quartzo, o qual emite em aproximadamente 8mm. Este grão seria produzido em uma fase evolutiva anterior a das carbonadas (estrelas S) e por terem uma estrutura cristalina são destruídos apenas na presença de campos de radiação ultravioleta muito intensos. Os modelos para os envoltórios utilizam o método de Monte Carlo para descrever o problema do transporte da radiação. As conclusões deste trabalho são: (1) as bandas de Merrill-Sanford se encontram em absorção, sugerindo um cenário usual para os ventos das estrelas da amostra; (2) neste cenário, a emissão em 8 mm seria resultado de grãos de quartzo com mantos de SiC, indicando que o quartzo poderia sobreviver a fase

  20. The Orthogonally Partitioned EM Algorithm: Extending the EM Algorithm for Algorithmic Stability and Bias Correction Due to Imperfect Data.

    Regier, Michael D; Moodie, Erica E M

    2016-05-01

    We propose an extension of the EM algorithm that exploits the common assumption of unique parameterization, corrects for biases due to missing data and measurement error, converges for the specified model when standard implementation of the EM algorithm has a low probability of convergence, and reduces a potentially complex algorithm into a sequence of smaller, simpler, self-contained EM algorithms. We use the theory surrounding the EM algorithm to derive the theoretical results of our proposal, showing that an optimal solution over the parameter space is obtained. A simulation study is used to explore the finite sample properties of the proposed extension when there is missing data and measurement error. We observe that partitioning the EM algorithm into simpler steps may provide better bias reduction in the estimation of model parameters. The ability to breakdown a complicated problem in to a series of simpler, more accessible problems will permit a broader implementation of the EM algorithm, permit the use of software packages that now implement and/or automate the EM algorithm, and make the EM algorithm more accessible to a wider and more general audience.

    Full Text Available O objetivo deste trabalho foi avaliar o desempenho agronômico das culturas do milho e do capim-xaraés (Urochloa brizantha 'Xaraés' em consórcio, cultivadas em plantio direto e convencional, em sistema agrossilvipastoril, com a aplicação de diferentes doses de nitrogênio em cobertura. O experimento foi conduzido em área de cultivo de milho com a espécie florestal mulateiro (Calycophyllum spruceanum. Utilizou-se o delineamento experimental de blocos ao acaso, com arranjo em parcelas subdivididas, com dois sistemas de manejo do solo (plantio direto e convencional com grade pesada alocados nas parcelas e com cinco doses de adubação nitrogenada em cobertura (0, 50, 100, 150 e 200 kg ha-1 de N, nas subparcelas, o que totalizou dez tratamentos. A produtividade de grãos de milho respondeu linearmente à aplicação de N em área de plantio convencional. Em área de plantio direto, a dose de 165 kg ha-1 de N em cobertura foi necessária para a obtenção de produtividades satisfatórias. A adubação nitrogenada em cobertura na cultura do milho, até a dose de 200 kg ha-1 de N, não influencia o rendimento do capim-xaraés em consórcio nas entrelinhas, após a colheita do milho.

    2002-01-01

    Full Text Available A natureza endêmica e sazonal da cólera depende da sobrevivência de Vibrio cholerae O1 em estado viável, mas não necessariamente cultivável em nichos ambientais aquáticos durante períodos interepidêmicos, sendo de suma importância o estudo da sobrevivência deste microrganismo nesses locais. Para tal, foram coletadas, semanalmente, alíquotas de água pertencentes a duas lagoas e dois rios do Estado do Rio de Janeiro. Esses volumes foram divididos em duas porções idênticas, uma das quais foi autoclavada. Uma diluição padronizada de V. cholerae O1 Inaba e de V. cholerae O1 Ogawa, foi inoculada em três alíquotas de 100ml dessas diferentes águas e mantidas em diferentes temperaturas. A sobrevivência desses microorganismos no âmbito aquático sob esses diferentes fatores foi então analisada. Os resultados demonstraram que o V. cholerae sorogrupo O1, independente do sorotipo, é capaz de se manter em água com salinidade abaixo de 0,5? e em diferentes temperaturas, por períodos suficientes para sua disseminação através de "corpos d'água", demonstrando a necessidade de monitoramento constante em áreas de possível contaminação, principalmente onde a água é utilizada para o consumo, evitando assim, a disseminação da doença para as populações próximas a esses ambientes.

O objetivo desta revisão foi coletar dados sobre tratamento da dor em queimados. CONTEÚDO: Foi feita revisão sobre os mecanismos de dor, avaliação do paciente com queimadura e o tratamento farmacológico e não farmacológico. CONCLUSÕES: O manejo da dor em pacientes vítimas de queimaduras ainda é um desafio por parte da equipe multiprofissional. A avaliação frequente e contínua da resposta apresentada pelo paciente é muito importante, tendo em vista os vários momentos por que passa o paciente internado em decorrência de uma queimadura, além de uma terapêutica combinada com medicações analgésicas e medidas não farmacológicas. Entender a complexidade de alterações fisiopatológicas, psicológicas e bioquímicas apresentadas por um paciente em tratamento de queimadura é o primeiro passo para alcançar o sucesso no seu manejo analgésico.

    Full Text Available Estudo qualitativo e descritivo, cujo objetivo foi identificar e analisar as representações sociais de educação em saúde à pessoa vivendo com HIV entre profissionais de saúde. Os cenários foram três serviços de atenção à DST/HIV/AIDS, em Belém-PA, Brasil, e 37 profissionais de saúde participaram da pesquisa. A coleta de dados deu-se em 2012-2013 por meio de entrevista em profundidade; a análise utilizou o software Alceste 4.10. Com base no conjunto dos resultados foi possível vislumbrar que a educação em saúde pode ser compreendida a partir de categorias: a configuração do agir educativo; as condições sine qua non: educação no trabalho e estrutura da unidade; o processo pedagógico. Conclui-se que as representações sociais configuram-se como orientação-informação para precaução-prevenção e revelam-se no movimento do agir persistente ao emergente, o que suscita uma educação em saúde permanente para se chegar à integralidade nos serviços.

    Full Text Available A compreensão da diversidade genética fornece elementos básicos sobre a dinâmica e funcionamento de populações, auxiliando na conservação e uso sustentável das espécies. Supõe-se que populações sucessionais precoces poderiam ser geneticamente mais diferenciadas do que populações sucessionais mais tardias. Visando testar esta hipótese, o presente trabalho teve como objetivo analisar a variabilidade genética de populações de Eugenia uniflora L. em manchas florestais em diferentes estádios sucessionais. Foram selecionadas duas áreas em diferentes estádios de sucessão, sendo a primeira em estádio inicial e a segunda em estádio avançado. A área de estudo apresenta um remanescente florestal em transição de Floresta Ombrófila Mista e Floresta Estacional Semidecídua. Por meio da técnica de RAPD (Random Amplified Polymorphic DNA e análise multivariada, a diversidade gênica esperada e a porcentagem de loci polimórficos foram estimadas, além da similaridade genética entre as populações de cada mancha florestal e a diversidade de cada área por meio do índice de diversidade de Simpson. Os resultados indicaram 79% de loci polimórficos para a área em estádio avançado e 70% para a área em estádio inicial de sucessão. A similaridade genética entre pares de indivíduos variou entre 0,55 e 0,86 na área em estádio inicial de sucessão e entre 0,45 e 0,78 para a área em estádio avançado. Não houve diferenças significativas entre a diversidade das duas áreas (P = 89. Um escalonamento multidimensional não-métrico indicou menor distância genética entre os indivíduos da área em estádio inicial. Da mesma forma, uma análise de similaridade - ANOSIM indicou separação entre os indivíduos das duas áreas.

    Full Text Available Abstract In order to evaluate the density of the red fox and of the domestic cat, 55 transects were made from 1986 to 1989 using spotlight census method in three sample areas. The mean density of foxes agreed substantially with its biological cycle and the hightes values (2.01 foxes/km² in spring and 4.3 foxes/km² in winter were recorded in the study area with the better natural characteristics. Foxes selected the shrub woodland (macchia all year round, the inhabited area in spring. The domestic cat was widely spread and abundant, and selected especially inhabited areas where the density varied from 4.27 cats/km² (in winter to 12.42 cat/km² (in spring. Riassunto Dal 1986 al 1989, con il metodo dei percorsi notturni con fari, sono stati effettuati complessivamente 55 conteggi in tre aree campione per valutare la densità della Volpe (<em>Vulpes vulpesem> e del Gatto domestico (<em>Felis catusem> nonché le loro preferenze ambientali limitatamente ad una zona campione. Per la Volpe le densità medie rilevate sono sostanzialmente in accordo con il ciclo biologico della specie e quelle più elevate (2,O1 volpi/km² in primavera e 4,3 volpi/km² in inverno sono state registrate nella zona campione con maggior presenza di boschi ed aree incolte. La Volpe seleziona le zone con vegetazione "di macchia" in ogni periodo dell'anno, e le aree abitate in primavera. Per il Gatto domestico le densità rilevate evidenziano la presenza di una diffusa ed abbondante popolazione. La specie mostra una spiccata preferenza per le aree abitate dove raggiunge densità di 4,27 individui/km² e 12,42 individui/km² in inverno e primavera rispettivamente.

  17. Non-medical exposures - Ethical concerns

    International Nuclear Information System (INIS)

    O'Reilly, G.

    2009-01-01

    The scope of the Medical Exposure Directive (MED), 97/43/Euratom (Council Directive 97/43/EURATOM, on the health protection of individuals against the dangers of ionising radiation in relation to medical exposures. OJ L 180 of 09.07.1997), is such that it includes not only those exposures which are part of the normal diagnosis and treatment of patients but also exposures for occupational health surveillance, health-screening programmes, research and medico-legal exposures. This is the first time that radiation protection legislation has tried to deal explicitly with the issue of medico-legal exposures in a European Directive. However, it has done so in the context of a Directive whose primary focus is the protection of patients undergoing diagnostic or therapeutic medical exposures. This may not be an appropriate framework for medico-legal exposures. In considering medico-legal exposures, a significant number of ethical considerations arise. The MED may not adequately take account of these matters and in fact may not be a suitable legal instrument for dealing with them. This paper looks specifically at the issues surrounding medico-legal exposures and considers whether or not the current system provides adequate protection for the individuals exposed. (authors)

    Full Text Available Deep-sea environments are largely unexplored habitats where a surprising number of species may be found in large communities, thriving regardless of the darkness, extreme cold, and high pressure. Their unique geochemical features result in reducing environments rich in methane and sulfides, sustaining complex chemosynthetic ecosystems that represent one of the most surprising findings in oceans in the last 40 years. The deep-sea Lucky Strike hydrothermal vent field, located in the Mid Atlantic Ridge, is home to large vent mussel communities where <em>Bathymodiolus azoricusem> represents the dominant faunal biomass, owing its survival to symbiotic associations with methylotrophic or methanotrophic and thiotrophic bacteria. The recent transcriptome sequencing and analysis of gill tissues from <em>B. azoricusem> revealed a number of genes of bacterial origin, hereby analyzed to provide a functional insight into the gill microbial community. The transcripts supported a metabolically active microbiome and a variety of mechanisms and pathways, evidencing also the sulfur and methane metabolisms. Taxonomic affiliation of transcripts and 16S rRNA community profiling revealed a microbial community dominated by thiotrophic and methanotrophic endosymbionts of <em>B. azoricusem> and the presence of a <em>Sulfurovum>-like epsilonbacterium.

    Full Text Available Different biological methods are gaining recognition for the production of silver nanoparticles (Ag-NPs due to their multiple applications. The use of plants in the green synthesis of nanoparticles emerges as a cost effective and eco-friendly approach. In this study the green biosynthesis of silver nanoparticles using <em>Callicarpa maingayi em>stem bark extract has been reported. Characterizations of nanoparticles were done using different methods, which include; ultraviolet-visible spectroscopy (UV-Vis, powder X-ray diffraction (XRD, transmission electron microscopy (TEM, scanning electron microscopy (SEM, energy dispersive X-ray fluorescence (EDXF spectrometry, zeta potential measurements and Fourier transform infrared (FT-IR spectroscopy. UV-visible spectrum of the aqueous medium containing silver nanoparticles showed absorption peak at around 456 nm. The TEM study showed that mean diameter and standard deviation for the formation of silver nanoparticles were 12.40 ± 3.27 nm. The XRD study showed that the particles are crystalline in nature, with a face centered cubic (fcc structure. The most needed outcome of this work will be the development of value added products from <em>Callicarpa maingayi em>for biomedical and nanotechnology based industries.

    Full Text Available With the fast development, in the last ten years, of a large choice of set-ups dedicated to routine <em>in vivoem> measurements in rodents, fluorescence imaging techniques are becoming essential tools in preclinical studies. Human clinical uses for diagnostic and image-guided surgery are also emerging. In comparison to low-molecular weight organic dyes, the use of fluorescent nanoprobes can improve both the signal sensitivity (better <em>in vivoem> optical properties and the fluorescence biodistribution (passive “nano” uptake in tumours for instance. A wide range of fluorescent nanoprobes have been designed and tested in preclinical studies for the last few years. They will be reviewed and discussed considering the obstacles that need to be overcome for their potential everyday use in clinics. The conjugation of fluorescence imaging with the benefits of nanotechnology should open the way to new medical applications in the near future.

    Sudden Infant Death Syndrome (SIDS) has been reported to be the leading cause of death in infants under 1 year of age in many countries. Unfortunately, a paucity of published research data exists in South Africa, with regard to the incidence of and investigation into the circumstances surrounding Sudden Unexplained Deaths in Infants (SUDI) and/or SIDS. Currently, even though most academic centers conform to a protocol consistent with internationally accepted standards, there exists no nationally accepted infant death investigation protocol in South Africa. It is the aim of this study to review the current practice of infant death investigation in two representative but geographically and demographically distinct centers. Retrospective case audit over a five-year period (2000-2004) was conducted at two large medico-legal mortuaries in Pretoria (Gauteng) and Tygerberg (Cape Town). Case files on all infants younger than 1 year of age were reviewed. The outcome measures included number of deaths, demographic details and the nature and final outcome of the post mortem examinations. A total of 512 cases were identified as possible SIDS cases and of these, 171 was classified as SIDS. The study showed marked inter-case and inter-divisional variation in terms of the investigation of infant deaths at the two institutions. It is envisaged that this study will focus attention on the current lack of usable data regarding sudden/unexplained/unexpected infant deaths in South Africa, and aid in the formulation and implementation of a practical (yet internationally accountable) infant death investigation protocol, which could facilitate comparisons with other countries and initiate further structured research in this field.

    An exit survey was returned by a sample of 127 respondents in fully compensated positions who left the EMS profession, most within 12 months prior to filling out the exit survey. A very high percentage continued to work after leaving EMS. Respondents were asked to rate the importance of each of 17 items in affecting their decision to leave EMS. A higher than anticipated response to a "not applicable" response choice affected the usability of 8 of these items. Nine of the 17 items had at least 65 useable responses and were used for further analysis. Within these 9, stress/burnout and lack of job challenges had the highest importance in affecting the decision to leave EMS, while desire for better pay and benefits had the lowest importance. Desire for career change was positively related to life satisfaction after leaving EMS and negatively related to likelihood of returning to EMS. Stress/burnout was positively related to life satisfaction after leaving EMS. Study limitations and future research issues are briefly discussed.

    Full Text Available Obesity is a global health problem. It is also known to be a risk factor for the development of metabolic disorders, type 2 diabetes, systemic hypertension, cardiovascular disease, dyslipidemia, and atherosclerosis. In this study, we elucidated that <em>Buddleja officinalis Maximowicz em>extract significantly inhibited lipid accumulation during 3T3-L1 adipocyte differentiation. Furthermore, <em>Buddleja officinalis Maximowicz em>extract reduced the body weight gain induced through feeding a high-fat diet to C57BL/6 mice. The treatment of <em>Buddleja officinalis Maximowicz em>extract significantly reduced the adipose tissue weight to 2.7/100 g of body weight in high-fat mice. When their adipose tissue morphology was investigated for histochemical staining, the distribution of cell size in the high-fat diet groups was hypertrophied compared with those from <em>Buddleja officinalis Maximowicz em>extract-treated mice. In addition, in <em>Buddleja officinalis Maximowicz em>extract-treated mice, a significant reduction of serum triglyceride and T-cholesterol was observed at to 21% and 17%, respectively. The discovery of bioactive compounds from diet or dietary supplementation is one of possible ways to control obesity and to prevent or reduce the risks of various obesity-related diseases. These results support that <em>Buddleja officinalis Maximowiczem> extract is expected to create the therapeutic interest with respect to the treatment of obesity.

Based on 16S rRNA-based polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE, 18 operational taxonomic units (OTUs were assigned to the five bacterial classes <em>Betaproteobacteria>, <em>Alphaproteobacteria>, <em>Gammaproteobacteria>, <em>Bacilli> and <em>Actinobacteria>. Nine OTUs were assigned to <em>Gammaproteobacteria>, which was the most highly represented class. <em>Enterobacteriaceae> constituted the dominant family, and within this family, three genera and five species were identified, including <em>Enterobacter sakazakiiem>, <em>Klebsiella> <em>oxytoca>, <em>Klebsiella> <em>pneumoniae,> Raoultellaem> <em>terrigena em>and <em>Enterobacter> <em>amnigenus>. In this set, the first two species were the dominant components, and the latter three species were the minor ones. Finally, we found that the metabolites produced by <em>R.> terrigenaem>, <em>K. oxytocaem> and <em>K.> pneumoniae em>were attractive to the <em>B.> dorsalisem> adults, and in field studies, <em>B.> dorsalisem> adults were most attracted to <em>K.> oxytocaem>. Collectively, our results suggest that the female reproductive system plays an important role in the transfer of enterobacteria from the gut to fruit. Our data may prompt the development of a female-targeted population control strategy for this fly.

    2017-01-01

    Gostaria de discutir, em forma de teses, a temática da historicidade da filosofia em contraste e na sua divergência em Hegel e Heidegger. Diferente do historicismo, que não soluciona o problema da historicidade da filosofia, porque ele dissolve tendencialmente a filosofia na história da filosofia e não coloca em especial a questão da verdade, Hegel e Heidegger desenvolvem uma teoria genuinamente filosófica da história da filosofia do interesse filosófico pela verdade. Esse interesse genuiname...

    Full Text Available O preparo e a consolidação do solo alteram a sua capacidade em resistir à erosão em sulcos. Com o objetivo de estudar a erosão em sulcos em diferentes preparos e consolidação do solo, conhecer o diâmetro mediano dos sedimentos transportados e determinar a erodibilidade em sulcos (Kr e a tensão crítica de cisalhamento (τc do solo, foi realizado um experimento no campo, em 1997/98, em um Argissolo Vermelho-Amarelo distrófico arênico. O delineamento experimental foi inteiramente casualizado com seis repetições. Os tratamentos constaram de: preparo convencional recente (CR, preparo convencional consolidado (consolidação de dois meses (CC, plantio direto sem palha (PDS e plantio direto com palha (PDC, 94% de cobertura. Usou-se chuva simulada de intensidade constante (65 mm h-1 até escoamento aproximadamente constante de água no solo. Em seguida, na extremidade superior do sulco, foram adicionadas descargas líquidas (Q crescentes de 0,0002 m³ s-1 até 0,0010 m³ s-1, para os tratamentos CR e CC, e de 0,0004 m³ s-1 até 0,0020 m³ s-1, para os tratamentos PDS e PDC, sendo as amostras coletadas na parte inferior de cada sulco. As parcelas foram delimitadas por chapas metálicas cravadas no solo no sentido do declive (0,20 m de largura por 6,00 m de comprimento. O valor de Kr determinado foi de 0,012 kg N-1 s-1 e o τc foi de 2,61 N m-2. A desagregação, as perdas de solo e o diâmetro mediano dos sedimentos apresentaram a seguinte seqüência em magnitude: CR, CC, PDS e PDC, particularmente nas maiores Q. O regime de escoamento foi turbulento supercrítico, com exceção da primeira Q aplicada, onde o regime foi laminar subcrítico, para o PDC, graças à presença de resíduos culturais, e laminar supercrítico, para os demais tratamentos. A consolidação e a cobertura do solo alteram o regime do escoamento e reduzem a erosão em sulcos e seus efeitos são complementares.

  3. Similarity-regulation of OS-EM for accelerated SPECT reconstruction

    Ordered subsets expectation maximization (OS-EM) is widely used to accelerate image reconstruction in single photon emission computed tomography (SPECT). Speedup of OS-EM over maximum likelihood expectation maximization (ML-EM) is close to the number of subsets used. Although a high number of subsets can shorten reconstruction times significantly, it can also cause severe image artifacts such as improper erasure of reconstructed activity if projections contain few counts. We recently showed that such artifacts can be prevented by using a count-regulated OS-EM (CR-OS-EM) algorithm which automatically adapts the number of subsets for each voxel based on the estimated number of counts that the voxel contributed to the projections. While CR-OS-EM reached high speed-up over ML-EM in high-activity regions of images, speed in low-activity regions could still be very slow. In this work we propose similarity-regulated OS-EM (SR-OS-EM) as a much faster alternative to CR-OS-EM. SR-OS-EM also automatically and locally adapts the number of subsets, but it uses a different criterion for subset regulation: the number of subsets that is used for updating an individual voxel depends on how similar the reconstruction algorithm would update the estimated activity in that voxel with different subsets. Reconstructions of an image quality phantom and in vivo scans show that SR-OS-EM retains all of the favorable properties of CR-OS-EM, while reconstruction speed can be up to an order of magnitude higher in low-activity regions. Moreover our results suggest that SR-OS-EM can be operated with identical reconstruction parameters (including the number of iterations) for a wide range of count levels, which can be an additional advantage from a user perspective since users would only have to post-filter an image to present it at an appropriate noise level.

    Gustavo J. Fonseca D'El Rey

    Full Text Available O medo de falar em público constitui um subtipo não reconhecido da fobia social em estudos epidemiológicos. Para se verificar a prevalência, o impacto no funcionamento pessoal e a procura por tratamento do medo de falar em público, foi realizada uma pesquisa com 452 residentes da cidade de São Paulo, Brasil. Trinta e dois porcento dos entrevistados reportaram ansiedade excessiva quando falavam para um grande grupo de pessoas. No total, 13% dos entrevistados relataram que o medo de falar em público resultou em grande interferência em seu trabalho, vida social e educação, ou causou sofrimento acentuado. Esta pesquisa apóia a inclusão de formas graves do medo de falar em público no constructo diagnóstico da fobia social e sugere, também, que essa ansiedade de falar em público pode ter um impacto negativo na vida de muitos indivíduos na comunidade.

    Full Text Available This study was undertaken to explore gum from <em>Bombax buonopozense em>calyxes as a binding agent in formulation of immediate release dosage forms using wet granulation method. The granules were characterized to assess the flow and compression properties and when compressed, non-compendial and compendial tests were undertaken to assess the tablet properties for tablets prepared with bombax gum in comparison with those prepared with tragacanth and acacia gums. Granules prepared with bombax exhibited good flow and compressible properties with angle of repose 28.60°, Carr’s compressibility of 21.30% and Hausner’s quotient of 1.27. The tablets were hard, but did not disintegrate after one hour. Furthermore, only 52.5% of paracetamol was released after one hour. The drug release profile followed zero order kinetics. Tablets prepared with bombax gum have the potential to deliver drugs in a controlled manner over a prolonged period at a constant rate.

Foi realizado durante três anos agrícolas em PLANOSSOLO Hidromórfico eutrófico arênico, instalado em local de onde foi retirada uma camada de solo de cerca de 30cm de profundidade. A adubação com N, P e K foi realizada de acordo com a recomendação técnica para a cultura. O delineamento experimental foi de blocos ao acaso com quatro repetições, constituído de um tratamento denominado "completo", contendo os micronutrientes boro (H3BO3, cobre (CuSO4, ferro (FeSO4, manganês (MnCl2, molibdênio (Na2MoO4 e zinco (ZnSO4 e de seis outros formados pela omissão de um micronutriente de cada vez, além de testemunha sem micronutrientes. Em 1996/97, foram aplicados 70g ha-1 Zn, 70g ha-1 Mn, 40g ha-1 Fe, 50g ha-1 B, 12,5g ha-1 Cu e 4g ha-1 Mo, via foliar, no perfilhamento e no início da formação do primórdio floral das plantas de arroz. Em 1997/98, foram utilizadas as mesmas soluções, porém com aplicação apenas no perfilhamento. Em 1998/99, as doses dos micronutrientes foram alteradas para 35g ha-1 Zn, 35g ha-1 Mn, 100g ha-1 B, 20g ha-1 Cu e 12g ha-1 Mo, aplicados no perfilhamento, não sendo utilizado o ferro no tratamento completo nem na composição dos demais tratamentos. A sistematização da área causou redução no teor de matéria orgânica, macro e micronutrientes, exceto o boro e aumento de alumínio no solo. Verificou-se que não houve efeito da aplicação foliar de micronutrientes no rendimento de grãos de arroz irrigado.

MÉTODOS: Foram utilizados os dados da Pesquisa Nacional de Saúde Bucal (SBBrasil 2010, em uma amostra de 7.247 crianças de 12 anos. Os dados foram coletados por meio de exames clínicos e entrevistas. As variáveis dependentes foram as prevalências de cárie (dentes permanentes cariados, perdidos ou obturados [CPOD] ≥ 1 e CPOD ≥ 4. Foram realizadas análises bivariadas (teste de Rao-Scott e multinível (regressão de Poisson. As variáveis individuais foram sociodemográficas, condição periodontal e relato de incômodo ao escovar os dentes. Os fatores contextuais foram a presença de água fluoretada, a porcentagem de domicílios ligados à rede de abastecimento de água e a renda mediana do município. RESULTADOS: A prevalência de CPOD ≥ 1 foi 56,0%. O CPOD médio foi igual a 2,04 (IC95% 1,76;2,31 e 22,2% das crianças tinham CPOD ≥ 4. A experiência de cárie foi significantemente mais elevada em crianças de cor de pele preta, parda e amarela; em famílias com renda mais baixa; em crianças com cálculo dentário ou sangramento gengival; e naquelas que relataram incômodo ao escovar. Viver em cidades sem água fluoretada, com menor cobertura da rede de abastecimento de água e com renda mediana baixa foram fatores contextuais associados à doença. CONCLUSÕES: A prevalência de cárie em crianças brasileiras de 12 anos foi baixa, de acordo com os critérios da Organização Mundial da Saúde. Houve significantes desigualdades geográficas e socioeconômicas nos níveis da doença.

    Full Text Available Abstract A grid-trapping (CMR Method of the Wood Mouse (<em>A. sylvaticusem> resident population was carried on three sample areas in a Mediterranean Oak-wood (Bosco della Ficuzza, Palermo. Fifty live traps were settled on a 0.5 ha grid at each sample area and permitted to calculate the Petersen-Lincoln Index (modified by Chapman. The relative density in the typical oak-wooded area (20.4/ha is highest than in the ecotonal and gazed sample area (12.6/ha. Analysis of ground permanence shows that the population in the wooded area is more dinamic than in the other area; in the former area a large number of new captures occurs, in fact, each month and the monthly variation of the relative density has a different trend. These results would confirm the indirect data coming from pellets analysis showing how in Sicily the highest densities occur in woodlands (oak-woods, as well as beech forests. The ecological niche of the Wood Mouse, due also to the apparent lack of <em>A. flavicollisem>, is thus larger than in peninsular Italy and continental Europe. The reproductive season lasts over the whole year but the birth peaks occurred in summer (1988 and late fall (1989. Population each year stabilizes for overwintering and later (Jun-Nov is almost completely renowed. Moreover, differences in sex and age trappability in relation to the two mode1 of traps utilized and a low mortality due to the cautions in handling the trapped mice, were recorded.

    The Electron Microscopy DataBank (EMDB) is growing rapidly, accumulating biological structural data obtained mainly by electron microscopy and tomography, which are emerging techniques for determining large biomolecular complex and subcellular structures. Together with the Protein Data Bank (PDB), EMDB is becoming a fundamental resource of the tertiary structures of biological macromolecules. To take full advantage of this indispensable resource, the ability to search the database by structural similarity is essential. However, unlike high-resolution structures stored in PDB, methods for comparing low-resolution electron microscopy (EM) density maps in EMDB are not well established. We developed a computational method for efficiently searching low-resolution EM maps. The method uses a compact fingerprint representation of EM maps based on the 3D Zernike descriptor, which is derived from a mathematical series expansion for EM maps that are considered as 3D functions. The method is implemented in a web server named EM-SURFER, which allows users to search against the entire EMDB in real-time. EM-SURFER compares the global shapes of EM maps. Examples of search results from different types of query structures are discussed. We developed EM-SURFER, which retrieves structurally relevant matches for query EM maps from EMDB within seconds. The unique capability of EM-SURFER to detect 3D shape similarity of low-resolution EM maps should prove invaluable in structural biology.

    Full Text Available O conhecimento de como a qualidade sanitária da matéria-prima afeta a qualidade dos seus subprodutos é muito importante para a indústria e para o consumidor. Para tanto foram analisadas 81 amostras de milho em grão, 81 de grits (canjica e 81 de fubá coletadas semanalmente antes e após o processamento, durante aproximadamente 4 meses, para determinar a contaminação interna dos grãos por fungos. Os grãos destas amostras foram lavados externamente com uma solução de hipoclorito de sódio à 2% e semeados em dois meios de cultura, Ágar Batata Dextrose e Ágar Suco de Tomate. O fubá não sofreu lavagem sendo colocado pequenas porções diretamente sobre os meios de cultura. Após a incubação à 25° C durante 4 a 7 dias, os fungos foram contados e identificados. Os fungos encontrados pertenciam aos gêneros Aspergillus, Fusarium, Penicillium, Mucor e Rhizopus. Amostras de fubá apresentaram a maior porcentagem de infecção fúngica, provavelmente originada da matéria prima e/ou das condições de processamento e/ou armazenamento do mesmo. Os fungos isolados das amostras de milho em grão, grits e fubá estão normalmente presentes em produtos e subprodutos armazenados, e alguns deles podem ser toxigênicos e vir a causar sérios problemas à saúde humana.

    Full Text Available The aim of this study was to investigate the cytotoxic and apoptotic effects of <em>Nephelium ramboutan-akeem> (pulasan rind in selected human cancer cell lines. The crude ethanol extract and fractions (ethyl acetate and aqueous of <em>N. ramboutan-akeem> inhibited the growth of HT-29, HCT-116, MDA-MB-231, Ca Ski cells according to MTT assays. The <em>N. ramboutan-akeem> aqueous fraction (NRAF was found to exert the greatest cytotoxic effect against HT-29 in a dose-dependent manner. Evidence of apoptotic cell death was revealed by features such as chromatin condensation, nuclear fragmentation and apoptotic body formation. The result from a TUNEL assay strongly suggested that NRAF brings about DNA fragmentation in HT-29 cells. Phosphatidylserine (PS externalization on the outer leaflet of plasma membranes was detected with annexin V-FITC/PI binding, confirming the early stage of apoptosis. The mitochondrial permeability transition is an important step in the induction of cellular apoptosis, and the results clearly suggested that NRAF led to collapse of mitochondrial transmembrane potential in HT-29 cells. This attenuation of mitochondrial membrane potential (Δ<em>ψ>m was accompanied by increased production of ROS and depletion of GSH, an increase of Bax protein expression, and induced-activation of caspase-3/7 and caspase-9. These combined results suggest that NRAF induces mitochondrial-mediated apoptosis.

    Migrant worker abuse is well recognised, but poorly characterised within the scientific literature. This study aimed to explore patterns of abuse amongst Sri Lankan women returning home after working as domestic maids. Sri Lanka has over 2 million of its citizens employed overseas as international labor migrants. A cross-sectional study was conducted on Sri Lankan female domestic maids returning from the Middle East region who were referred for medico-legal opinion. A total of 20 women were included in the study. Average length of their employment overseas was 14 months. Complaints of physical violence directed mainly through their employers were made by 60% of women. Upon physical examination, two-thirds had evidence of injuries, with a third being subjected to repetitive/systematic violence. Eighty percent suffered some form of psychological trauma. Personal identity papers and travel documents had been confiscated by the employer in 85% of cases, with two thirds indicating they were prevented and/or restricted from leaving their place of work/residence. Our study demonstrates that female domestic maid abuse manifests through multiple pathways. Violence against such workers span the full spectrum of physical, financial, verbal, emotional abuse and neglect, as defined by the World Health Organization. Findings from this exploratory study cannot be generalized to the large volume of migrant worker outflows. Further research is needed to determine incidence and define patterns in other migrant worker categories such as low-skilled male workers.

    Full Text Available OBJETIVO: avaliar a acurácia do sintoma tosse como um critério diagnóstico de tuberculose pulmonar (TBP em pacientes internados em um hospital universitário. MÉTODOS: foi conduzida uma avaliação de teste diagnóstico em pacientes com idade ≥15 anos internados em hospital geral de Niterói-RJ, Brasil, em 2011 e 2012. RESULTADOS: foram incluídos 3.677 pacientes, dos quais 608 apresentaram tosse e 15 foram diagnosticados com TBP; entre 184 pacientes sintomáticos respiratórios, 10 foram diagnosticados com TBP; a acurácia do sintoma tosse para a identificação de pacientes com TB foi de 83,4%; a ausência de tosse revelou-se um bom indicador para o descarte do diagnóstico (valor preditivo negativo de 99,7%; todavia, o valor preditivo positivo foi baixo (0,99. CONCLUSÃO: a tosse produtiva apresentou boa acurácia, embora, isoladamente, não seja um bom sintoma de rastreio da TBP em ambientes hospitalares; torna-se necessário identificar outros sintomas e sinais para rastreio e diagnóstico precoce em hospitais.

  11. Riqueza e densidade de aves que nidificam em cavidades em plantações abandonadas de eucalipto

    Full Text Available Monoculturas de árvores, como as de espécies de eucalipto, têm substituído florestas naturais, impactando a fauna pela perda de habitat e recursos. Diversas espécies de aves necessitam de ocos em árvores para nidificar. A falta de recursos como cavidades formadas pela degradação da árvore ou locais apropriados para serem criadas cavidades leva a diminuição na abundância das populações destas espécies. Este trabalho tem o objetivo de comparar a riqueza e a densidade de aves que nidificam em ocos em áreas de plantação de eucalipto abandonadas com áreas de vegetação nativa em duas unidades de conservação em Minas Gerais. Em cada tipo de vegetação de cada reserva foram estabelecidos 25 pontos, nas quais foi utilizado o método de contagem por remoção para o levantamento das espécies de aves. A riqueza de espécies de aves de cada área foi estimada por Jackniffe e a densidade foi estimada através do método de máxima verossimilhança; modelos candidatos que poderiam influenciar a abundância das aves foram avaliados utilizando-se o Critério de Informação Akaike (AIC. Os resultados mostraram que a riqueza de espécies foi maior nas áreas de florestas nativas e que a densidade foi significantemente mais alta nas áreas de florestas nativas, e que o tipo de vegetação e a hora do dia influenciam na abundância e detecção das aves. Esses resultados indicam que as plantações de eucaliptos influenciam negativamente a comunidade de aves que nidificam em ocos, provavelmente por causa da falta de cavidades ou de sub-bosque. Plantações de eucaliptos normalmente não substituem as florestas nativas e seu uso deve ser controlado em áreas de conservação.

Quarenta e dois porcento desses tumores eram de origem mesenquimal; 37% eram epiteliais; 14,5% eram derivados da crista neural; 5% eram tumores do cordão sexual; e 1,5 eram tumores originários do sistema nervoso periférico. O tumor mais frequentemente encontrado foi o linfoma (28% de todos os tumores, a maioria dos casos como parte do complexo leucose bovina enzoótica. O carcinoma de células escamosas foi o segundo tumor mais frequente (15% de todos os tumores. É chamada a atenção para a frequência desses tumores e para a sua importância no diagnóstico diferencial no abatedouro frigorífico entre eles e outras lesões importantes, incluindo as lesões granulomatosas da tuberculose. Houve uma ocorrência significativa do feocromocitoma adrenal (13% de todos os tumores. Papilomatose representou apenas 3% de todos os tumores. Como papilomas são comuns em bovinos, seu baixo número nesse estudo pode ser explicado pelo fato de que eles não são usualmente diagnosticados no exame post mortem (quando o couro já foi retirado da carcaça, mas sim no exame ante mortem, como ocorreu na maioria dos casos deste estudo. Tumores encontrados com menor frequência (cada um perfazendo entre 1.5 e 3% de todos os tumores incluíram adenocarcinoma apócrino misto da cauda, adenocarcinoma mamário, adenocarcinoma uterino, carcinoma de células renais, fibroma interdigital, hemangiossarcoma, leiomioma uterino, lipoma, lipossarcoma, mesotelioma, neurofibroma, tumor de células da granulosa, tumor estromal gastrointestinal, tumores hepáticos, tumores melanocíticos, e tumores pulmonares primários.

    2017-12-01

    By 2030, road traffic accidents are projected to be the fifth leading cause of death worldwide, with 90% of these deaths occurring in low- and middle-income countries (LMICs). While high-quality, prehospital trauma care is crucial to reduce the number of trauma-related deaths, effective Emergency Medical Systems (EMS) are limited or absent in many LMICs. Although lay providers have long been recognized as the front lines of informal trauma care in countries without formal EMS, few efforts have been made to capitalize on these networks. We suggest that lay providers can become a strong foundation for nascent EMS through a four-fold approach: strengthening and expanding existing lay provider training programs; incentivizing lay providers; strengthening locally available first aid supply chains; and using technology to link lay provider networks.

  1. Communication - An Effective Tool for Implementing ISO 14001/EMS

    Energy Technology Data Exchange (ETDEWEB)

    Rachel Damewood; Bowen Huntsman

    2004-04-01

    The Idaho National Engineering and Environmental Laboratory (INEEL) received ISO 14001/EMS certification in June 2002. Communication played an effective role in implementing ISO 14001/EMS at the INEEL. This paper describes communication strategies used during the implementation and certification processes. The INEEL achieved Integrated Safety Management System (ISMS) and Voluntary Protection Program (VPP) Star status in 2001. ISMS implemented a formal process to plan and execute work. VPP facilitated worker involvement by establishing geographic units at various facilities with employee points of contact and management champions. The INEEL Environmental Management System (EMS) was developed to integrate the environmental functional area into its ISMS and VPP. Since the core functions of ISMS, VPP, and EMS are interchangeable, they were easy to integrate. Communication is essential to successfully implement an EMS. (According to ISO 14001 requirements, communication interacts with 12 other elements of the requirements.) We developed communication strategies that integrated ISMS, VPP, and EMS. For example, the ISMS, VPP, and EMS Web sites communicated messages to the work force, such as “VPP emphasizes the people side of doing business, ISMS emphasizes the system side of doing business, and EMS emphasizes the systems to protect the environment; but they all define work, identify and analyze hazards, and mitigate the hazards.” As a result of this integration, the work force supported and implemented the EMS. In addition, the INEEL established a cross-functional communication team to assist with implementing the EMS. The team included members from the Training and Communication organizations, VPP office, Pollution Prevention, Employee and Media Relations, a union representative, facility environmental support, and EMS staff. This crossfunctional team used various communication strategies to promote our EMS to all organization levels and successfully implemented EMS

Dessa forma, o objetivo desse trabalho foi realizar o levantamento da população de ácaros associados às plantas ornamentais no município de Arapiraca-AL, em função dos diversos problemas acarretados por essa espécie. O levantamento foi realizado entre os meses de abril a março, através de amostragens mensais de folhas coletadas da parte basal, intermediária e apical de plantas existentes em praças e jardins. Foram coletados 55 ácaros pertencentes à ordem Prostigmata em 20 famílias de plantas. As plantas com as maiores riquezas de ácaros foram as Coleus blumei L. e Bxuxus sempervirens L., que apresentaram 65% dos valores amostrais. Analisando-se as coletas realizadas, pode-se observar que houve uma maior incidência populacional de ácaros na coleta do mês de maio, cuja percentagem foi de 36% de ácaros levantados, sendo que no levantamento dos dados amostrais de março a percentagem encontrada foi de 14%, nas amostragens dos meses de abril e junho, a percentagem amostrada dos dados foi de 22 e 28%, respectivamente. O estudo do levantamento de ácaros em plantas ornamentais permitiu observar a relação entre ácaros e a relação com a planta hospedeira, facilitando posteriormente um estudo mais aprofundado sobre plantas hospedeiras, e pode-se observar que em períodos chuvosos ocorre uma menor incidência populacional.

    Full Text Available Abstract Oxygen consumption (VO2 and body temperature (Tb were measured in the Asian Garden Dormouse, <em>Eliomys melanurusem>, from a population inhabiting the semi-arid steppe habitats of the Negev Highlands in Israel. Prior to measurements, the animals were acclimated for at least three weeks to an ambient temperature of 24°C with a photoperiod regime of 12L:12D. The results of this study reveal that the resting metabolic rates of this species are relatively low and that even at Ta=25°C they may enter daily periods of torpor which can save up to 65% of the average daily energy expenditure of a normothermic individual under the same conditions. The emergence from torpor is accompanied by an overshoot in VO2. Both normothermic dormice and those in torpor show a daily rhythm of VO2 and Tb with a clear pattern of a nocturnal species. Riassunto Termoregolazione e ritmicità di <em>Eliomys melanurusem> della regione montuosa del Negev, Israele - Il consumo di ossigeno (VO2 e la temperatura corporea (Tb sono stati misurati nel topo quercino asiatico, <em>Eliomys melanurusem>, proveniente da una popolazione che in Israele abita ambienti steppici semi-aridi della regione montuosa del Negev. Prima delle misurazioni, gli animali sono stati acclimatati per almeno tre settimane ad una temperatura ambiente di 24°C con un fotoperiodo di 12L:12D. I risultati di questo studio rivelano che i tassi metabolici di questa specie in condizioni di riposo sono relativamente bassi e che anche a Ta=25°C possono entrare in periodi di torpore giornalieri che permettono di salvare fino a1 65% del consumo medio energetico giornaliero di un individuo normotermico alle stesse condizioni. Il risveglio dal torpore è accompagnato da un aumento di VO2. Sia i Mioxidi normotermici che quelli in torpore mostrano

    Full Text Available Este trabalho é parte de uma pesquisa maior em que estou analisando discursivamente práticas coletivas de escrita observáveis em propostas de oficinas de textos em determinados espaços da internet. Aqui me ocupo particularmente de uma experiência francesa de produção de textos que descrevem cenas ocorridas na cidade de Paris. Detenho-me precisamente na proposta de um site na internet que convida os internautas a participar da produção de uma coletânea de descrições curtas, estruturadas segundo um conjunto de regras, mostrando cenas do cotidiano parisiense. Para o objetivo deste artigo, primeiramente apresento a proposta, desenvolvimento e estrutura deste site que é ponto de partida da análise. Em seguida, concentro-me no processo coletivo de escrita que particulariza esta experiência. Nesta parte, ocupo-me do corpus de escritos atentando para as rasuras que indicam os sucessivos estágios de reformulação por que passaram nas sessões de oficinas de escrita que observei in loco. O eixo teórico vem do que Eni Orlandi tem proposto acerca do discurso como pertinente à ordem simbólica e do texto como forma material referente à ordem da organização. Meu interesse não é focalizar a conversão deste corpus de rascunhos em textos nos termos da sistematicidade da língua na qual se desenvolve a prática em questão, o que implicaria um trabalho específico sobre o sistema do francês. O que me interessa, no quadro de uma teoria discursiva da subjetividade, é estudar a dimensão singular do acontecimento que torna possível a vigência de uma prática textual a múltiplas vozes e pontos de vistas submetidos a certo ato protocolar de escritura

    Full Text Available De acordo com o Banco Mundial, desde o final dos anos 2000 o movimento de aquisição de terras por estrangeiros tem se acentuado nos países em desenvolvimento, impulsionado pelo boom dos preços das commodities. Em termos teóricos, a abordagem da Nova Economia Institucional (NEI argumenta que as instituições são importantes para as estratégias dos agentes econômicos e seu desempenho. Neste estudo, apoiado na NEI, pretende-se responder como as instituições presentes em países periféricos refletem o processo de aquisições de terras por investidores estrangeiros. Para esse objetivo, foram utilizados dados secundários de organizações internacionais, como Food and Agriculture Organization, Banco Mundial, Conferência das Nações Unidas sobre Comércio e Desenvolvimento, Fundo Monetário Internacional, Organização para a Cooperação Econômica e Desenvolvimento Econômico, Wall Street Journal e agências nacionais. A hipótese principal é que a força ou a fraqueza presente no ambiente institucional em países em desenvolvimento tem influência relevante no nível de Investimento Estrangeiro Direto (IED. Para testar a hipótese, adota-se como metodologia a análise estatística, na qual se verifica a relação entre o nível de IED nos países receptores (variável dependente contra variáveis independentes: liberdade de investimento, direitos de propriedade e nível de corrupção.

    Full Text Available

    This essay examines African American novelist Pauline Hopkins’s deployment of the trope of respectable domesticity to contest black disenfranchisement in the context of African Americans’ ambivalent relationship to late-nineteenth-century US imperial expansion in the Asia Pacific. This essay analyzes <em>Contending Forcesem> (1900 in relation to two crucial yet underexplored contexts: first, Hopkins’s commentaries on international race relations; second, African American intellectuals’ commentaries on US imperial ventures in the Asia Pacific and on Chinese immigration in the <em>Colored American Magazineem>, where Hopkins’s fictional works were serialized. Situated within these contexts of comparative racialization, Hopkins’s works offer critical responses to the masculine nationalist representations of black–Asian relations, illuminating the divisive effects of nationalist identification on differentially racialized subjects, the uneven effects of marriage on the black community, and this institution’s structural ties to imperialism and to the color-based class hierarchy within the imagined black community—all of which call for radical reimagining of race relations beyond the nation form.

    Full Text Available Black cumin (<em>Nigella> <em>sativa> L., Ranunculaceae is an annual herb commonly used in the Middle East, India and nowadays gaining worldwide acceptance. Historical and traditional uses are extensively documented in ancient texts and historical documents. Black cumin seeds and oil are commonly used as a traditional tonic and remedy for many ailments as well as in confectionery and bakery. Little is known however about the mechanisms that allow the accumulation and localization of its active components in the seed. Chemical and anatomical evidence indicates the presence of active compounds in seed coats. Seed volatiles consist largely of olefinic and oxygenated monoterpenes, mainly <em>p->cymene, thymohydroquinone, thymoquinone, γ-terpinene and α-thujene, with lower levels of sesquiterpenes, mainly longifolene. Monoterpene composition changes during seed maturation. γ-Terpinene and α-thujene are the major monoterpenes accumulated in immature seeds, and the former is gradually replaced by <em>p>-cymene, carvacrol, thymo-hydroquinone and thymoquinone upon seed development. These compounds, as well as the indazole alkaloids nigellidine and nigellicine, are almost exclusively accumulated in the seed coat. In contrast, organic and amino acids are primarily accumulated in the inner seed tissues. Sugars and sugar alcohols, as well as the amino alkaloid dopamine and the saponin α-hederin accumulate both in the seed coats and the inner seed tissues at different ratios. Chemical analyses shed light to the ample traditional and historical uses of this plant.

Os bovinos afetados tinham acesso a antigas lavouras de soja ou restevas de lavouras de soja e milho altamente infestados por fedegoso (S. occidentalis. No estabelecimento 1, de um total de 34 novilhas (de aprox. 18 meses de idade, 10 morreram (29,1%; no estabelecimento 2, morreram 9 (4,2% de um total de 212 vacas prenhes e, no estabelecimento 3, morreram 6 (12,0% de um total de 50 animais. O curso clínico variou de 3 a 6 dias, e os sinais clínicos incluíam urina marrom-escura, fraqueza muscular, tremores, andar cambaleante, decúbito esternal e morte. Os animais, mesmo em decúbito, permaneciam alerta e com reflexos normais, alimentando-se e bebendo água até poucas horas antes da morte. No estabelecimento 2, os bovinos começaram a adoecer 7 dias após terem sido retirados do campo infestado pela planta. As principais alterações observadas na necropsia foram áreas claras na musculatura esquelética, principalmente nos músculos dos membros posteriores e estrias esbranquiçadas na musculatura cardíaca. A principal lesão microscópica era de degeneração e necrose nos músculos esqueléticos (miopatia degenerativa tóxica multifocal multifásica. Os dados epidemiológicos, clínicos, de necropsia e histopatológico permitiram concluir pelo diagnóstico de intoxicação por S. occidentalis, nesses três surtos.

    Full Text Available RESUMO Os morcegos filostomídeos são potenciais dispersores de sementes, devido ao seu hábito de forrageio e grande mobilidade, sendo os principais responsáveis pela regeneração de florestas neotropicais. No Mato Grosso do Sul as pesquisas com dieta de morcegos se concentram na região do Pantanal, com poucos trabalhos focados na porção de Cerrado, e somente um em área urbana. O objetivo deste estudo foi analisar a dieta de filostomídeos frugívoros em dois remanescentes urbanos de Cerrado em Campo Grande, Mato Grosso do Sul, avaliando-se se a formulação da dieta das espécies é baseada em preferências alimentares específicas ou não. Os morcegos foram capturados em duas unidades de conservação (a Estação Ecológica Dahma e o Parque Estadual do Prosa por 12 noites em cada área, usando-se seis redes-de-neblina, que permaneceram abertas durante seis horas a partir do ocaso. Após a captura, cada morcego foi mantido em saco de algodão individual por uma hora para coleta das fezes. As amostras fecais foram armazenadas individualmente em frasco hermético e imersas em glicerina, sendo posteriormente analisadas em laboratório. Todas as sementes encontradas nas amostras foram identificadas. Foram capturados 250 morcegos, distribuídos em dez espécies, oito gêneros e duas famílias. Os filostomídeos constituíram 93,2% das capturas (n=233. As espécies mais frequentes foram Carollia perspicillata (Linnaeus, 1758 (27,6% e Artibeus lituratus (Olfers, 1818 (27,2%. Foram encontradas sementes em 46 amostras fecais de sete espécies de morcegos filostomídeos. A maioria das sementes encontradas era da família Piperaceae (69,6% das amostras, sendo um recurso-chave consumido por quase todas as espécies de filostomídeos. Os frugívoros auxiliam na manutenção de unidades de conservação, pois promovem a auto-renovação, sendo a frugivoria um processo importante em remanescentes florestais.

    Full Text Available <em>Fusarium> <em>verticillioides> is the primary causal agent of Fusarium ear and kernel rot in maize, producing fumonisin mycotoxins that are toxic to humans and domestic animals. Rapid detection and monitoring of fumonisin-producing fungi are pivotally important for the prevention of mycotoxins from entering into food/feed products. Chicken-derived single-chain variable fragments (scFvs against cell wall-bound proteins from <em>F. verticillioidesem> were isolated from an immunocompetent phage display library. Comparative phage enzyme-linked immunosorbant assays (ELISAs and sequencing analyses identified four different scFv antibodies with high sensitivity. Soluble antibody ELISAs identified two highly sensitive scFv antibodies, FvCA3 and FvCA4, with the latter being slightly more sensitive. Three-dimensional modeling revealed that the FvCA4 may hold a better overall structure with CDRH3, CDRL1 and CDRL3 centered in the core region of antibody surface compared with that of other scFvs. Immunofluorescence labeling revealed that the binding of FvCA4 antibody was localized to the cell walls of conidiospores and hyphae of <em>F. verticillioidesem>, confirming the specificity of this antibody for a surface target. This scFv antibody was able to detect the fungal mycelium as low as 10−2 μg/mL and contaminating mycelium at a quantity of 10−2 mg/g maize. This is the first report that scFv antibodies derived from phage display have a wide application for rapid and accurate detection and monitoring of fumonisin-producing pathogens in agricultural samples.

    Full Text Available The objective of this study was to evaluate the reactivity of an in-house antigen, extracted from a strain of <em>C. posadasii em>isolated in northeastern Brazil, by radial immunodiffusion and Western blotting, as well as to establish its biochemical characterization. The protein antigen was initially extracted with the use of solid ammonium sulfate and characterized by 1-D electrophoresis. Subsequently, it was tested by means of double radial immunodiffusion and Western blotting. A positive reaction was observed against the antigen by both immunodiagnostic techniques tested on sera from patients suffering from coccidioidomycosis. Besides this, two immunoreactive protein bands were observed and were revealed to be a β-glucosidase and a glutamine synthetase after sequencing of the respective N-terminal regions. Our in-house <em>Coccidioides> antigen can be promising as a quick and low-cost diagnostic tool without the risk of direct manipulation of the microorganism.

    Prior studies have highlighted wide variation in emergency medical services (EMS) workplace safety culture across agencies. To determine the association between EMS workplace safety culture scores and patient or provider safety outcomes. We administered a cross-sectional survey to EMS workers affiliated with a convenience sample of agencies. We recruited these agencies from a national EMS management organization. We used the EMS Safety Attitudes Questionnaire (EMS-SAQ) to measure workplace safety culture and the EMS Safety Inventory (EMS-SI), a tool developed to capture self-reported safety outcomes from EMS workers. The EMS-SAQ provides reliable and valid measures of six domains: safety climate, teamwork climate, perceptions of management, working conditions, stress recognition, and job satisfaction. A panel of medical directors, emergency medical technicians and paramedics, and occupational epidemiologists developed the EMS-SI to measure self-reported injury, medical errors and adverse events, and safety-compromising behaviors. We used hierarchical linear models to evaluate the association between EMS-SAQ scores and EMS-SI safety outcome measures. Sixteen percent of all respondents reported experiencing an injury in the past three months, four of every 10 respondents reported an error or adverse event (AE), and 89% reported safety-compromising behaviors. Respondents reporting injury scored lower on five of the six domains of safety culture. Respondents reporting an error or AE scored lower for four of the six domains, while respondents reporting safety-compromising behavior had lower safety culture scores for five of the six domains. Individual EMS worker perceptions of workplace safety culture are associated with composite measures of patient and provider safety outcomes. This study is preliminary evidence of the association between safety culture and patient or provider safety outcomes.

It produces a thermo-stable proteinaceous substance, bacteriocin (enterocin EM41 with the highest inhibition activity in late logarithmic phase of growth (25 600 AU/ml. This strain and its enterocin have not been previously tested in animals. Lohmann Brown laying hens (aged 45 weeks were involved in this model/pilot experiment, divided into 3 groups 6 birds in each. E. faecium EM41 applied was a variant treated with rifampicin (109 cfu/ml, dose 400 μl/animal/day to differentiate it from the other enterococci. Partially-purified enterocin EM41 (Ent EM41, dose 40 μl/animal/day and its producer were applied to water for 21 days. The experiment lasted 35 days. Sampling was performed at days 0 - 1, 21 (3 weeks of additive application, 35 (2 weeks after cessation of additive application from every bird. E. faecium EM41 sufficiently colonized the intestinal tract of laying hens from the initial concentration 109 cfu/g, its count reached 4.30 log cfu/g at day 21. PCR genotypization confirmed the identity of the EM41 strain with the species Enterococcus faecium. E. faecium EM41 and its enterocin EM41 showed antimicrobial effects demonstrated by reduction of coagulase-positive and coagulase-negative staphylococci, coliforms, Pseudomonas spp., Aeromonas spp. and Campylobacter spp. The hens were Salmonella spp. free. After administration of both additives, phagocytic activity was stimulated with a significant increase. The additives did not negatively influence biochemical and haematological parameters or weight gains.

    Late embryogenesis abundant (LEA) proteins are closely related to abiotic stress tolerance of plants. In the present study, we identified a novel Em-like gene from lettuce, termed LsEm1, which could be classified into group 1 LEA proteins, and shared high homology with Cynara cardunculus Em protein. The LsEm1 protein contained three different 20-mer conserved elements (C-element, N-element, and M-element) in the C-termini, N-termini, and middle-region, respectively. The LsEm1 mRNAs were accumulated in all examined tissues during the flowering and mature stages, with a little accumulation in the roots and leaves during the seedling stage. Furthermore, the LsEm1 gene was also expressed in response to salt, dehydration, abscisic acid (ABA), and cold stresses in young seedlings. The LsEm1 protein could effectively reduce damage to the lactate dehydrogenase (LDH) and protect LDH activity under desiccation and salt treatments. The Escherichia coli cells overexpressing the LsEm1 gene showed a growth advantage over the control under drought and salt stresses. Moreover, LsEm1-overexpressing rice seeds were relatively sensitive to exogenously applied ABA, suggesting that the LsEm1 gene might depend on an ABA signaling pathway in response to environmental stresses. The transgenic rice plants overexpressing the LsEm1 gene showed higher tolerance to drought and salt stresses than did wild-type (WT) plants on the basis of the germination performances, higher survival rates, higher chlorophyll content, more accumulation of soluble sugar, lower relative electrolyte leakage, and higher superoxide dismutase activity under stress conditions. The LsEm1-overexpressing rice lines also showed less yield loss compared with WT rice under stress conditions. Furthermore, the LsEm1 gene had a positive effect on the expression of the OsCDPK9, OsCDPK13, OsCDPK15, OsCDPK25, and rab21 (rab16a) genes in transgenic rice under drought and salt stress conditions, implying that overexpression of these

    Full Text Available Este trabalho analisa a realidade do ensino de língua espanhola em escolas de Ensino Fundamental e Médio da cidade de Pelotas (RS. A ideia surgiu a partir de observações realizadas na disciplina de Estágio de Observação, do curso de Português e Espanhol da UFPel, no semestre 2015/1, a partir do momento em que se pôde perceber que o que o estagiário encontra em sala de aula não condiz com o que é estudado, principalmente em aulas de Linguística Aplicada. Para este estudo, utilizaram-se relatos obtidos pelo autor deste trabalho e de mais quatro informantes, os quais estagiaram em escolas da rede pública pelotense no mesmo período. A análise comparativa fundamentou-se principalmente em textos de teorias de aprendizagem de línguas estrangeiras e nos PCN’s para o ensino de LE’s no Brasil, de modo a contrastar o que afirmam os teóricos e o que realmente encontrou-se nas escolas. Este estudo ancora-se na abordagem qualitativa e na metodologia aplicada por serem formas de pesquisa mais relacionadas às experiências humanas, suas interpretações terem carácter mais flexível e por permitirem uma melhor aplicação ao ensino e aprendizagem de LE. Os resultados obtidos indicam que a realidade do ensino de espanhol nas escolas difere do que ensinam os professores na universidade, pois se percebeu que o ensino dessa língua é precário, não indo ao encontro do que sugerem os PCN’s, no que se refere à transformação do aluno em agente discursivo em LE.Palavras-chave: aprendizagem, espanhol, língua estrangeira.

    Full Text Available Os liquens, associações entre fungos e algas unicelulares ou cianobactérias, são encontrados em muitos ambientes sobre vários substratos inclusive sobre troncos de árvores. Os liquens foliosos da família Parmeliaceae são bastante comuns nos ambientes brasileiros. Mesmo sendo comuns há ainda poucos levantamentos da diversidade de liquens em ambientes urbanos. Este estudo realizou um levantamento de espécies de fungos liquenizados por meio de uma coleta relâmpago em 17 forófitos de uma avenida no município de Lorena. Foram coletados 43 talos de liquens dos quais 70% são da família Parmeliaceae e estão distribuídos em seis gêneros e 21 espécies, sendo Parmotrema e Canomaculina os gêneros mais frequentes e Parmotrema tinctorum a espécie mais coletada. Pode se concluir que mesmo em ambientes não ideais, como os urbanos, há diversidade de espécies de fungos liquenizados.

    Full Text Available The extract from <em>Ginkgo bilobaem> leaves has become a very popular plant medicine and herbal supplement for its potential benefit in alleviating symptoms associated with peripheral vascular disease, dementia, asthma and tinnitus. Most research on <em>G. bilobaem> leaves focus on the leaves collected in July and August from four to seven year-old trees, however a large number of leaves from fruit cultivars (trees older than 10 years are ignored and become obsolete after fruit harvest season (November. In this paper, we expand the tree age range (from one to 300 years and first comparatively analyze the total flavonol glycosides and terpene lactones at different ages, from different cultivation sources and genders of <em>G. bilobaem> leaves collected in November by using the validated HPLC-ELSD and HPLC-PDA methods. The results show that the contents of total terpene lactones and flavonol glycosides in the leaves of young ginkgo trees are higher than those in old trees, and they are higher in male trees than in female trees. Geographical factors appear to have a significant influence on the contents as well. These results will provide a good basis for the comprehensive utilization of <em>G.> biloba em>leaves, especially the leaves from fruit cultivars.

  17. Quality control procedures of dental diagnostic radiology systems; Elaboracao de um procedimento para controle de qualidade em sistemas de radiodiagnostico odontologico

    Andrade, Paula Serra Sasaki

    2007-07-01

    This work presents quality control reference procedures for dental diagnostic radiology systems, following the recommendations of the Publication 453 of the Brazilian Health Ministry (PF453), to be applied in dental clinics, in order to achieve an improvement in the radiological image qualities and the patient dose reduction. All tests were applied in an intraoral X rays system, following the methodology developed and the requirements of the PF 453. In order to verify the best quality of the image in relation to the smaller exposition time an object test was also developed in this work. The use of this object allowed the reduction of the exposition time of 0.5 seconds, the maximum value of the linear region of the characteristic curve, for 0.2 seconds. The tested X rays system showed a very good agreement with the applied procedures, detaching the reduction of the skin entrance dose using the film-holding devices. However, the size of the field increased and exceeded the maximum value of 6 cm recommended in the standard. The importance of the quality control in dental diagnostic radiology systems is essential due to the constant use of X radiation in dental clinics. The PF453 recommends the frequency of at least two years for the constancy tests. However, it is suggested that the professional, surgeon-dentist, should be responsible for the internal control of the image quality obtained from the X rays device. This can be done through monthly exposures of the object test developed in this work. (author)

    Full Text Available Abstract We collected data on the reproduction of <em>Nyctalus noctulaem> in Hungary by mist-netting and monitoring bat boxes. The capture or observation of juveniles and lactating females were considered evidence of breeding. A total of 1413 <em>N. noctulaem> were mist-netted in four study areas, corresponding to 24 new breeding locations for Hungary. In southern Hungary, one breeding colony with 20-25 individuals was observed in a bat box in a protected park, while another was found in the hollow of a white poplar. Twenty lactating females and 3 juveniles were mist-netted in the Zemplén Mountains. Our data document the regular breeding of the species in Hungary, the breeding area being wider than previously reported. Further breeding colonies are likely to be located in the floodplain forests of some main rivers, such as the Tisza and the Danube.

    Peat soil is known as geotechnical problematic soil since it is the softest soil having highly organic and moisture content which led to high compressibility, low shear strength and long-term settlement. The aim of this study was to obtain the stabilized peat soils using the Effective Microorganisms (EM). The volume of EM added and mixed with peat soils varied with 2%, 4%, 6%, 8% and 10% and then were cured for 7, 14 and 21 days. The experiment was done for uncontrolled and controlled moisture content. Prior conducting the main experiments, the physical properties such as moisture content, liquid limit, specific gravity, and plastic limit etc. were measure for raw peat samples. The Unconfined Compressive Strength (UCS) test was performed followed by regression analysis to check the effect of EM on the soil strength. Obtained results have shown that the mix design for controlled moisture contents showed the promising improvement in their compressive strength. The peat soil samples with 10% of EM shows the highest increment in UCS value and the percentage of increments are in the range of 44% to 65% after curing for 21 days. The regression analysis of the EM with the soil compressive strength showed that in controlled moisture conditions, EM significantly improved the soil stability as the value of R2 ranged between 0.97 – 0.78. The results have indicated that the addition of EM in peat soils provides significant improving in the strength of the soil as well as the other engineering properties.

    Full Text Available Abstract There is little information about the status and ecology of the Eurasian otter (<em>Lutra lutraem> in Iran. We assessed the habitat suitability for otters of the River Jajrood, Tehran province, measuring, or visually estimating, 12 environmental parameters along 16 600 m long river stretches (sampling sites. The downstream stretches of the river were found to be more suitable for otters with respect to the upper part of its course. Although the assessments of habitat suitability for the otter may be affected by several limits, the current distribution of the species on the river agrees with the results of this study. The preservation of the otter in Tehran province should involve the restoration of the ecosystem of the River Jajrood in order to improve the length of suitable river stretches.

L’idoneità ambientale per la specie del fiume Jajrood, provincia di Tehran, è stata valutata, misurando o stimando 12 parametri ambientali lungo 16 stazioni di campionamento, coincidenti con tratti di fiume della lunghezza di 600 m. I tratti più a valle sono risultati più idonei rispetto al corso superiore del fiume. Malgrado i numerosi limiti del metodo di stima dell’idoneità ambientale adottato, i risultati sono in accordo con l’attuale distribuzione della lontra lungo il fiume Jajrood. La conservazione della lontra nella provincia di Tehran dovrebbe prevedere miglioramenti ambientali volti a incrementare lo sviluppo lineare degli habitat idonei lungo il fiume Jajrood.

    Full Text Available O girassol (Helianthus annuus L., que é comumente cultivado para produção de sementes e óleo, também apresenta potencial de uso como planta ornamental. Entretanto, seu porte elevado dificulta essa utilização, principalmente como flor em vaso. Objetivou-se neste experimento avaliar os efeitos do regulador de crescimento paclobutrazol sobre o crescimento de plantas de girassol em vaso, cultivadas em sistema hidropônico, dentro de estufa, em vasos preenchidos com sílica moída. Os dois genótipos de girassol utilizados foram BRS Oásis, com capítulo marrom e altura média de 1,85 m, e Helio 358, com capítulo amarelo e altura média de 1,45 m. As doses de paclobutrazol avaliadas foram 0; 0,5; 1; 2; 4; e 6 mg L-1 , aplicadas diretamente no substrato de sílica moída. A solução nutritiva utilizada foi a de Hoagland, e as plantas foram mantidas sob aeração constante. O delineamento experimental foi o de blocos casualizados, em esquema fatorial com cinco repetições, totalizando 60 parcelas. Avaliaram-se a altura das plantas e a massa de matéria seca de raiz, caule, folhas e de capítulos. Houve efeito do paclobutrazol sobre o crescimento das plantas. O uso do paclobutrazol na dose de 2mgL-1 reduz a altura do girassol, porém não afeta a qualidade da inflorescência, o que pode viabilizar o seu uso na produção de flores de girassol como ornamentais. A sensibilidade ao paclobutrazol é maior para o genótipo Helio 358 em relação ao genótipo BRS Oásis.

    Full Text Available Foi caracterizada a heterogeneidade ambiental em uma área de floresta de galeria (7,55 ha, em Itutinga, MG, Brasil, pelas variações das propriedades químicas e físicas do solo, da topografia e da abertura de dossel. As propriedades do solo e a topografia foram estudadas em 28 parcelas de 10 x 30 m utilizadas em um levantamento da comunidade arbóreo-arbustiva da área. Para a abertura do dossel utilizaram-se duas transecções de 50 m de largura, compostas por parcelas contíguas de 10 x 10 m, cruzando a floresta de lado a lado, perpendicularmente ao curso d’água. Fotos hemisféricas foram tomadas sobre estacas alternadas das extremidades das parcelas. Os dados de solo e topografia foram analisados por meio de uma PCA (Análise dos Componentes Principais e a abertura do dossel mediante gráficos de tendência e regressão linear. A variação mais importante em termos de solos e abertura do dossel se deu no sentido do distanciamento da borda da floresta e aproximação do curso d’água. Nesse sentido, a abertura do dossel diminuiu (b = -0,096; R2 = 0,34 e a umidade e acidez do solo aumentaram (Eixo 1 do PCA, autovalor = 9,713. Os maiores valores da abertura do dossel próximo à borda foram explicados pela entrada de luz lateral através da borda da floresta com o campo limpo circundante.

  7. Dor lombar crônica e dor nos membros inferiores em idosas: etiologia em revisão

    Renata Maraschin

    Full Text Available INTRODUÇÃO: A relação entre dor lombar crônica, dor nos membros inferiores e dependência funcional em idosos evidencia-se pelo comportamento da dor durante a execução de atividades da vida diária. Permanecer em pé, puxar ou empurrar objetos grandes e caminhar podem desencadear dor e causar grande sofrimento para os idosos. OBJETIVO: Identificar as causas descritas na literatura relativas à dor lombar crônica e à dor nos membros inferiores em idosas. MÉTODO: Realizou-se busca, nas bases de dados Medline e Pubmed, de literatura em inglês publicada entre 1992 e 2008. RESULTADOS: Dos 48 artigos encontrados, 33 foram analisados. Entre as causas não mecânicas de dor, foram mencionadas fraturas vertebrais por compressão relacionadas à osteoporose, estenose espinhal lombar, metástases, malignidade, síndrome da cauda equina, bacteremia, infecções geniturinárias, tuberculose, polimialgia reumática, aneurisma aórtico, Doença de Paget e Doença de Parkinson. Entre as causas mecânicas, prevalentes em idosos e relacionadas ao sistema musculoesquelético, foram encontradas indefinições quanto à relação de causa e efeito estabelecida entre osteoartrite e dor. Em mulheres, a relação entre menopausa, uso de estrogênio e ocorrência de osteoporose-fratura-dor parece ainda pouca esclarecida. Associação entre dor lombar e dor nos membros inferiores pode sugerir causas mecânicas ou outras causas, visto que osteoartrite e distúrbios circulatórios, comuns em idosas, nem sempre são fontes de dor. CONCLUSÃO: Pela análise da literatura concluiu-se que, além da etiologia mencionada, outras possibilidades de causas, ainda não completamente identificadas e compreendidas, podem estar na origem da dor lombar e da dor nos membros inferiores de idosas.

    2016-10-01

    Full Text Available Introdução: A escabiose consiste em uma doença contagiosa causada pelo ácaro Sarcoptes scabie, parasita exclusivo da pele humana, transmitida pelo contato direto com pessoa infectada. Pode ocorrer em qualquer faixa etária, independente do sexo, etnia ou hábitos de higiene, sendo diagnosticada com base na história de coceira noturna, associada a lesões cutâneas. Em geral, há mais de um caso na mesma residência. Apresenta diversos diagnósticos diferenciais por ser essencialmente uma dermatite. Objetivo: Alertar para possibilidade de escabiose na comunidade. Metodologia: As informações contidas nesse relato foram obtidas por meio de consultas médicas, registros fotográficos, evolução, hipóteses diagnósticas e revisão de literatura. Relato de Caso: E.T.L.T, sexo feminino. Aos 21 dias de vida, mãe relata vermelhidão nas costas da paciente e ao exame físico observa-se eritema máculo papular na região de transição parieto-occipital do crânio. A conduta baseia-se em orientação quanto à lavagem de roupa de cama com sabão de coco, remoção de xampu e talco e observação do rash cutâneo. Treze dias depois, mãe refere piora das manchas vermelhas e aparecimento de lesões em tórax anterior e posterior, pescoço e face. Relata ainda, ter cachorro em casa e lesões semelhantes em seu próprio tórax e mamas antes mesmo de a criança nascer. A orientação foi mantida, além de ser receitado enxofre precipitado a 10% para a mãe e a 5% para a criança. Após cinco dias de tratamento, as manchas regrediram e a paciente voltou a ser amamentada. Conclusão: A escabiose continua a ser uma dermatose frequente, cujo tratamento em idade pediátrica se restringe aos “steps” para o diagnóstico correto, desinfecção dos fômites e uso de um bom escabicida, tanto para a criança quanto para seus cuidadores.

  18. NECESSIDADE E LIBERDADE EM HANNAH ARENDT

    Directory of Open Access Journals (Sweden)

    Odílio Alves Aguiar

    2015-07-01

    Full Text Available O presente artigo visa refletir sobre o pensamento de Hannah Arendt à luz do par conceitual necessidade-liberdade. Esse caminho é produtivo, pois dá conta tanto da obra mais conhecida e reconhecida da autora quanto das suas reflexões anteriores à Origens do Totalitarismo, que se dirigiam, na sua maioria, à comunidade dos Judeus e tinham a questão judaica como ponto central. As meditações arendtianas sobre o judaísmo, consideradas no presente artigo, foram publicadas em duas coletâneas na França: La tradition Cachée (1987 e Auschwitz et Jérusalem (1991. O artigo gravita em torno da defesa arendtiana sobre a inerência entre política e liberdade e sua substituição pela compreensão da política como submetida à esfera da necessidade. Essa perspectiva, segundo a autora, fez-se presente na tradição assimilacionista entre os judeus, mas já tinha obtido a hegemonia na cultura ocidental. Isso sucedeu em razão da primazia da vita contemplativa sobre a vita activa, do trabalho e da questão social em detrimento da ação e, por fim, da supremacia da filosofia da história em prejuízo da Filosofia Política.

    2014-02-01

    Full Text Available Com o crescente interesse da literatura econômica sobre o ativismo do governo, percebe-se que este passa a influenciar a atividade produtiva e econômica no Brasil de maneira mais intensa (Fucs & Coronato, 2011. Sob a ótica da teoria da estratégia política corporativa, o principal objetivo deste trabalho é analisar a estrutura de propriedade com participação societária do governo nas empresas brasileiras listadas na BM&FBovespa, no período de 1999 a 2010. O estudo explora a presença do governo em diversas esferas, sendo elas federais, estaduais e municipais nas estruturas de propriedade das empresas brasileiras listadas na BM&FBovespa, o que demonstra seu ineditismo em relação a outros estudos no país. Considera duas formas de identificação do governo como acionista: direta (empresas públicas, empresa estatais, autarquias federais, bancos de desenvolvimento nacional ou regional, fundos de desenvolvimento social e fundos de participação social e indireta (fundos de pensão de empresas públicas e estatais, segregando-as em participação majoritária ou minoritária. Entre os principais resultados encontrados, primeiramente se confirmou o pressuposto de estudos anteriores, que investigam a estrutura de propriedade no Brasil, de que a maioria das empresas brasileiras listadas na BM&FBovespa possui estrutura de propriedade concentrada, indicando a existência da figura de um acionista majoritário. Foi encontrado que em média o maior acionista possui 62,77% do capital votante, e 49,78 do capital total das empresas. Também os resultados encontrados indicam que o governo, quando compõe a estrutura de propriedade das firmas, tem participação relevante na economia, chegando a participar diretamente em 13,71% das empresas abertas negociadas na BM&FBovespa, sendo que nos últimos 12 anos possuiu, em média, 49,72% das ações com direito a voto e 39,01% do total de ações de cada empresa, o que indica que o governo controla as

    Full Text Available Problematiza a atuação de professores que ensinam matemática em classes multisseriadas de escolas ribeirinhas da Amazônia paraense. Enfatizaram-se questões acerca do ensino-aprendizagem, no âmbito da alfabetização matemática, desenvolvidas em escolas situadas às margens ou nas proximidades dos rios da região nordeste do Pará. Os dados foram construídos com base em informações dadas por seis professores em sete escolas municipais. Os resultados identificam que a alfabetização matemática expressa no contexto ribeirinho ainda se restringe às experiências matemáticas estritamente baseadas em orientações didáticas e curriculares de âmbito global, sem levar em consideração a riqueza de possibilidades de conhecimentos sugeridas pelas experiências dos estudantes em seu contexto diário.

Furthermore, the results of high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS analysis of the anthocyanins extracted from the fruit skin of downy rose-myrtle revealed the presence of five anthocyanin components, which were tentatively identified as delphinidin-3-glucoside, cyanidin-3-glucoside, peonidin-3-glucoside, petunidin-3-glucoside and malvidin-3-glucoside.

  6. Using Reversed MFCC and IT-EM for Automatic Speaker Verification

    2012-01-01

    Full Text Available This paper proposes text independent automatic speaker verification system using IMFCC (Inverse/ Reverse Mel Frequency Coefficients and IT-EM (Information Theoretic Expectation Maximization. To perform speaker verification, feature extraction using Mel scale has been widely applied and has established better results. The IMFCC is based on inverse Mel-scale. The IMFCC effectively captures information available at the high frequency formants which is ignored by the MFCC. In this paper the fusion of MFCC and IMFCC at input level is proposed. GMMs (Gaussian Mixture Models based on EM (Expectation Maximization have been widely used for classification of text independent verification. However EM comes across the convergence issue. In this paper we use our proposed IT-EM which has faster convergence, to train speaker models. IT-EM uses information theory principles such as PDE (Parzen Density Estimation and KL (Kullback-Leibler divergence measure. IT-EM acclimatizes the weights, means and covariances, like EM. However, IT-EM process is not performed on feature vector sets but on a set of centroids obtained using IT (Information Theoretic metric. The IT-EM process at once diminishes divergence measure between PDE estimates of features distribution within a given class and the centroids distribution within the same class. The feature level fusion and IT-EM is tested for the task of speaker verification using NIST2001 and NIST2004. The experimental evaluation validates that MFCC/IMFCC has better results than the conventional delta/MFCC feature set. The MFCC/IMFCC feature vector size is also much smaller than the delta MFCC thus reducing the computational burden as well. IT-EM method also showed faster convergence, than the conventional EM method, and thus it leads to higher speaker recognition scores.

  7. The DOE/EM facility transition program

    1994-01-01

    The mission of EM-60 is to plan, implement, and manage receipt of surplus facilities resulting from downsizing of the DOE Weapons Complex facilities and DOE operating program offices to EM, and to ensure prompt deactivation of such facilities in order to reach a minimum surveillance and maintenance condition. The revised organizational structure of EM-60 into four offices (one at headquarters, and the other three at field sites), reflects increased operating functions associated with deactivation, surveillance, and maintenance of facilities. EM-60's deactivation and transition role concerns technical, socioeconomic, institutional, and administrative issues. The primary objective of the deactivation process is to put facilities in the lowest surveillance and maintenance condition safely and quickly by driving down the open-quotes mortgageclose quotes costs of maintaining them until final disposition. EM-60's three key activities are: (1) Inventory of surplus facilities - The 1993 Surplus Facility Inventory and Assessment (SFIA) serves as a planning tool to help the Department and EM-60 determine optimal transition phasing, with safety and cost-effectiveness remaining a priority. (2) Management of accelerated facility life cycle transition - Transitions currently underway illustrate site issues. These include addressing the interests of federal and state regulatory agencies as well as interests of local stakeholders, safe management of large amounts of production residues, and options for treatment, storage, transportation, and disposal. Of equal importance in the transition process is planning the optimal transition of the labor force. (3) Economic development - to address the socio-economic impacts on affected communities of the severe and rapid downsizing of the DOE Weapons Complex, DOE is pursuing an approach that uses the land, equipment, technology assets, and highly skilled local workforces as a basis for alternative economic development

    2008-10-01

    Full Text Available The term plateau iris was first coined in 1958 to describe the iris configuration of a patient. Two years later the concept of plateau iris was published. In 1977, the plateau iris configuration was classically defined as presurgical changes of an eye with a relative normal central anterior chamber depth, flat iris by conventional biomicroscopy, but displaying an extremely narrow or closed angle on gonioscopic examination. On the other hand, the plateau iris syndrome was defined as an acute glaucoma crisis in one eye with a relative normal central anterior chamber depth and patent iridotomy on direct examination, presenting angle closure confirmed by gonioscopic examination after mydriasis. In 1992, the anatomic aspects of plateau iris were studied using ultrasound biomicroscopy. Finally, plateau iris has been considered an anatomic variant of iris structure in which the iris periphery angulates sharply forward from its insertion point and then again angulates sharply and centrally backward, along with an anterior positioning of the ciliary processes seen on ultrasound biomicroscopy. The clinical treatment of plateau iris syndrome is carried out with topical use of pilocarpine. However, the definitive treatment should be fulfilled by performing an argon laser peripheral iridoplasty.O termo íris em platô foi primeiramente inventado em 1958 para descrever a configuração da íris de um paciente.

    Full Text Available A polpa da carambola contém compostos químicos com propriedades antioxidantes importantes à saúde humana, contra o envelhecimento celular e a prevenção de doenças. Este trabalho objetivou avaliar o fruto de acessos de caramboleira quanto às concentrações de compostos antioxidantes. Foram analisadas as concentrações de ácido ascórbico, carotenoides totais, flavonoides, fenólicos totais e taninos em cinco acessos selecionados de carambola, cultivada em três distintas regiões edafoclimáticas de Pernambuco. Os acessos de carambola diferiram significativamente entre si, quanto às concentrações de ácido ascórbico, fenólicos totais e taninos. A significância para os efeitos de ambiente confirmou que os locais de cultivo são heterogêneos, em relação ao potencial produtivo de frutos com diferentes concentrações médias de ácido ascórbico, flavonóis, fenólicos totais e taninos. A interação significativa entre genótipos e ambientes indica que os acessos de carambola apresentam respostas diferenciadas às concentrações de ácido ascórbico, flavonóis, fenólicos totais e taninos, quando cultivadas em diferentes locais. As condições de cultivo da Estação Experimental do IPA Itambé e os acessos IPA-7.2, IPA-22.3 proporcionaram as maiores concentrações de ácido ascórbico, fenólicos totais e taninos.

    Full Text Available Resumo: A utilização da Musicoterapia em portadores do Transtorno do Espectro Autista (TEA teve início na década de 60 e mostrou promover benefícios, tais como: diminuição de crises comportamentais, diminuição de resistência ao tratamento, melhora nos relacionamentos interpessoais, aquisição de liberdade expressiva, aquisição da melhora vocal, melhora na comunicação, aquisição de confiança verbal e vocal, aquisição de ordem rítmica e melhora na produção da fala e mutualidade (BRANDALISE, 2013. Objetivo: embora os resultados em nível comunicacional sejam de amplo conhecimento e na busca por compreender o impacto da música nos biomarcadores imunológicos e de estresse nesses indivíduos, o presente artigo tem por objetivo apresentar uma breve revisão dos estudos recentes acerca dessa temática. Método: Foram utilizadas ferramentas de busca nas bases de dados PubMed, Lilacs, Cochrane e Scielo. A busca foi realizada em artigos publicados em português e inglês, por meio dos descritores “imunoglobulina”, “cortisol salivar”, “dano celular” e “autismo”. Resultado: por meio da pesquisa foi possível constatar a influência da música como um meio complementar no cuidado de portadores do TEA, enquanto instrumento de promoção da saúde e melhoria de qualidade de vida desses indivíduos. Considerações finais: Embora os estudos apontem os benefícios da música em portadores do TEA, sugere-se que sejam realizadas mais pesquisas nesse campo, sobretudo no Brasil. Portanto, o presente artigo se propõe como base teórica para uma posterior pesquisa-intervenção a fim de verificar os possíveis efeitos provocados por diferentes tipos de escuta musical sobre os indicadores de cortisol salivar, imunoglobulina A e dano celular de células epiteliais, bem como nos aspectos comportamentais, em crianças portadoras do Transtorno do Espectro Autista. A segunda fase da pesquisa já está em desenvolvimento, por meio do
