We need to teach human rights in medical schools

There are protocols of the questioning of a young military physician in the Israeli Defense Forces, who performed a vaginal examination on a Palestinian woman under arrest, against the latter’s expressed will and without a medical indication. In support of the WMA guidelines on including human rights courses in medical schools, we call on medical schools to integrate a human rights perspective and introduce sufficient material on human rights, prisoners’ rights and medical ethics to help physicians like her make the right decisions in challenging situations such as the one described

Recognition and treatment of law enforcement violence against detainees and prisoners: A survey among Israeli physicians and medical students

Introduction: Physicians regularly encounter victims of violence. Although some at-risk groups are increasingly recognized as such, the risks faced by prisoners and detainees are often overlooked. The scope of violence against them is unknown and their treatment is often hampered by unique social and institutional impediments. This article reviews the need for improved recognition and protection of such patients and the associated obstacles, while presenting information on the experience, knowledge and attitudes of physicians in Israel regarding the maltreatment of prisoners and detainees. Methods: We sent a questionnaire to physicians and medical students in Israel to enquire about their knowledge concerning examination and treatment of persons under police custody who appear to be victims of violence as well as their attitude concerning torture. Results: We received answers from443 physicians and 114 medical students. Most physicians would correctly examine and document the injuries, but only 59% would report their suspicions of violence to the Ministry of Health. Though 60% of physicians objected in principle to the use of torture, a majority endorsed the use of physical and psychological pressure during interrogation. Moreover, 29% of physicians thought it is permissible for physicians to examine detainees and verify their health so that torture can begin or continue. Discussion: Our study shows that there is a need for development and implementation of treatment and reporting protocols as well as educational programs concerning the ethical and legal requirements of physicians towards detainees and prisoners in Israel. Limitations of our study are discussed

MultiFit: a web server for fitting multiple protein structures into their electron microscopy density map

Advances in electron microscopy (EM) allow for structure determination of large biological assemblies at increasingly higher resolutions. A key step in this process is fitting multiple component structures into an EM-derived density map of their assembly. Here, we describe a web server for this task. The server takes as input a set of protein structures in the PDB format and an EM density map in the MRC format. The output is an ensemble of models ranked by their quality of fit to the density map. The models can be viewed online or downloaded from the website. The service is available at; http://salilab.org/multifit/ and http://bioinfo3d.cs.tau.ac.il/

Experiences regarding nutrition and exercise among women during early postpartum: A qualitative grounded theory study

Background: Excess gestational weight gain has long- and short-term implications for women and children, and postpartum weight retention is associated with an increased risk of long-term obesity. Despite the existence of dietary and exercise guidelines, many women struggle to return to pre-pregnancy weight. Experiences of women in tackling postpartum weight loss are poorly understood. We undertook this study to explore experiences related to nutrition, exercise and weight in the postpartum in women in Ontario, Canada. Methods: This was a nested qualitative study within The Be Healthy in Pregnancy Study, a randomized controlled trial. Women randomized to the control group were invited to participate. Semi-structured focus groups were conducted at 4-6 months postpartum. Focus groups were audio recorded, transcribed verbatim, coded and analyzed thematically using a constructivist grounded theory approach. Results: Women experienced a complex relationship with their body image, due to unrealistic expectations related to their postpartum body. Participants identified barriers and enablers to healthy habits during pregnancy and postpartum. Gestational weight gain guidelines were regarded as unhelpful and unrealistic. A lack of guidance and information about weight management, healthy eating, and exercise in the postpartum period was highlighted. Conclusion: Strategies for weight management that target the unique characteristics of the postpartum period have been neglected in research and in patient counselling. Postpartum women may begin preparing for their next pregnancy and support during this period could improve their health for subsequent pregnancies

A new structural framework for integrating replication protein A into DNA processing machinery

By coupling the protection and organization of single-stranded DNA (ssDNA) with recruitment and alignment of DNA processing factors, replication protein A (RPA) lies at the heart of dynamic multi-protein DNA processing machinery. Nevertheless, how RPA coordinates biochemical functions of its eight domains remains unknown. We examined the structural biochemistry of RPA’s DNA-binding activity, combining small-angle X-ray and neutron scattering with all-atom molecular dynamics simulations to investigate the architecture of RPA’s DNA-binding core. The scattering data reveal compaction promoted by DNA binding; DNA-free RPA exists in an ensemble of states with inter-domain mobility and becomes progressively more condensed and less dynamic on binding ssDNA. Our results contrast with previous models proposing RPA initially binds ssDNA in a condensed state and becomes more extended as it fully engages the substrate. Moreover, the consensus view that RPA engages ssDNA in initial, intermediate and final stages conflicts with our data revealing that RPA undergoes two (not three) transitions as it binds ssDNA with no evidence for a discrete intermediate state. These results form a framework for understanding how RPA integrates the ssDNA substrate into DNA processing machinery, provides substrate access to its binding partners and promotes the progression and selection of DNA processing pathways

Structural and Mechanistic Studies of Measles Virus Illuminate Paramyxovirus Entry

Measles virus (MeV), a member of the paramyxovirus family of enveloped RNA viruses and one of the most infectious viral pathogens identified, accounts for major pediatric morbidity and mortality worldwide although coordinated efforts to achieve global measles control are in place. Target cell entry is mediated by two viral envelope glycoproteins, the attachment (H) and fusion (F) proteins, which form a complex that achieves merger of the envelope with target cell membranes. Despite continually expanding knowledge of the entry strategies employed by enveloped viruses, our molecular insight into the organization of functional paramyxovirus fusion complexes and the mechanisms by which the receptor binding by the attachment protein triggers the required conformational rearrangements of the fusion protein remain incomplete. Recently reported crystal structures of the MeV attachment protein in complex with its cellular receptors CD46 or SLAM and newly developed functional assays have now illuminated some of the fundamental principles that govern cell entry by this archetype member of the paramyxovirus family. Here, we review these advances in our molecular understanding of MeV entry in the context of diverse entry strategies employed by other members of the paramyxovirus family

γ-TEMPy: simultaneous fitting of components in 3D-EM maps of their assembly using a genetic algorithm

We have developed a genetic algorithm for building macromolecular complexes using only a 3D-electron microscopy density map and the atomic structures of the relevant components. For efficient sampling the method uses map feature points calculated by vector quantisation. The fitness function combines a mutual information score that quantifies the goodness-of-fit with a penalty score that helps to avoid clashes between components. Testing the method on ten assemblies (containing 3 to 8 protein components) and simulated density maps at 10, 15, and 20 Å resolution resulted in identification of the correct topology in 90%, 70% and 60% of the cases, respectively. We further tested it on four assemblies with experimental maps at 7.2-23.5 Å resolution, showing the ability of the method to identify the correct topology in all cases. We have also demonstrated the importance of the map feature-point quality on assembly fitting in the lack of additional experimental information
