Attitude and Myths Towards Rape among Medical Students in Rajkot, India
Background: Violence against women takes many forms – physical, sexual, psychological and economic. Violence against women harms families and communities across generations and reinforces other violence prevalent in society. Rape myths encompass a set of (false) beliefs about rape that places the blame on the victim and not the perpetrator. Objective: to assess the prevailing attitudes on rape myths among the medical students. Methods: The study was conducted after taking informed consent among 346 undergraduate medical students of P D U Government Medical College, Rajkot, India from January to June, 2013 by using previously validated questionnaire using updated Illinois Rape Myth Acceptance Scale. Results: The age range of 346 medical students was 17 to 23 years with 172 male and 174 female students. Total 24.4% male and 23% female students had very good positive attitude. One fourth of male and one fifth of female students had a more negative attitude. No relation was observed for rape myth acceptance among medical students for residential or socio-economic status. Conclusion: The present study provides insight to the prevalence of attitude and rape myths towards rape among medical students. Introduction of education on gender violence with introduction of courses on ‘sexual violence’ in medical curriculum may help to decrease rape incidence and for better management of victims
The curvature tensor of (\ka,\mu,\nu)-contact metric manifolds
We study the Riemann curvature tensor of (\kappa,\mu,\nu)-contact metric
manifolds, which we prove to be completely determined in dimension 3, and we
observe how it is affected by D_a-homothetic deformations. This prompts the
definition and study of generalized (\kappa,\mu,\nu)-space forms and of the
necessary and sufficient conditions for them to be conformally flat
Impact of multi-professional, scenario-based training on postpartum hemorrhage in Tanzania: a quasi-experimental, pre- vs. post-intervention study
Ordering of mutations in preinvasive disease stages of esophageal carcinogenesis.
Cancer genome sequencing studies have identified numerous driver genes, but the relative timing of mutations in carcinogenesis remains unclear. The gradual progression from premalignant Barrett's esophagus to esophageal adenocarcinoma (EAC) provides an ideal model to study the ordering of somatic mutations. We identified recurrently mutated genes and assessed clonal structure using whole-genome sequencing and amplicon resequencing of 112 EACs. We next screened a cohort of 109 biopsies from 2 key transition points in the development of malignancy: benign metaplastic never-dysplastic Barrett's esophagus (NDBE; n=66) and high-grade dysplasia (HGD; n=43). Unexpectedly, the majority of recurrently mutated genes in EAC were also mutated in NDBE. Only TP53 and SMAD4 mutations occurred in a stage-specific manner, confined to HGD and EAC, respectively. Finally, we applied this knowledge to identify high-risk Barrett's esophagus in a new non-endoscopic test. In conclusion, mutations in EAC driver genes generally occur exceptionally early in disease development with profound implications for diagnostic and therapeutic strategies
BioCreative III interactive task: an overview
The BioCreative challenge evaluation is a community-wide effort for evaluating text mining and information extraction systems applied to the biological domain. The biocurator community, as an active user of biomedical literature, provides a diverse and engaged end user group for text mining tools. Earlier BioCreative challenges involved many text mining teams in developing basic capabilities relevant to biological curation, but they did not address the issues of system usage, insertion into the workflow and adoption by curators. Thus in BioCreative III (BC-III), the InterActive Task (IAT) was introduced to address the utility and usability of text mining tools for real-life biocuration tasks. To support the aims of the IAT in BC-III, involvement of both developers and end users was solicited, and the development of a user interface to address the tasks interactively was requested

The Evolution of Invasiveness in Garden Ants
It is unclear why some species become successful invaders whilst others fail, and whether invasive success depends on pre-adaptations already present in the native range or on characters evolving de-novo after introduction. Ants are among the worst invasive pests, with Lasius neglectus and its rapid spread through Europe and Asia as the most recent example of a pest ant that may become a global problem. Here, we present the first integrated study on behavior, morphology, population genetics, chemical recognition and parasite load of L. neglectus and its non-invasive sister species L. turcicus. We find that L. neglectus expresses the same supercolonial syndrome as other invasive ants, a social system that is characterized by mating without dispersal and large networks of cooperating nests rather than smaller mutually hostile colonies. We conclude that the invasive success of L. neglectus relies on a combination of parasite-release following introduction and pre-adaptations in mating system, body-size, queen number and recognition efficiency that evolved long before introduction. Our results challenge the notion that supercolonial organization is an inevitable consequence of low genetic variation for chemical recognition cues in small invasive founder populations. We infer that low variation and limited volatility in cuticular hydrocarbon profiles already existed in the native range in combination with low dispersal and a highly viscous population structure. Human transport to relatively disturbed urban areas thus became the decisive factor to induce parasite release, a well established general promoter of invasiveness in non-social animals and plants, but understudied in invasive social insects
Towards screening Barrett’s Oesophagus: current guidelines, imaging modalities and future developments
Barrett’s oesophagus is the only known precursor to oesophageal adenocarcinoma (OAC). Although guidelines on the screening and surveillance exist in Barrett’s oesophagus, the current strategies are inadequate. Oesophagogastroduodenoscopy (OGD) is the gold standard method in screening for Barrett’s oesophagus. This invasive method is expensive with associated risks negating its use as a current screening tool for Barrett’s oesophagus. This review explores current definitions, epidemiology, biomarkers, surveillance, and screening in Barrett’s oesophagus. Imaging modalities applicable to this condition are discussed, in addition to future developments. There is an urgent need for an alternative non-invasive method of screening and/or surveillance which could be highly beneficial towards reducing waiting times, alleviating patient fears and reducing future costs in current healthcare services. Vibrational spectroscopy has been shown to be promising in categorising Barrett’s oesophagus through to high-grade dysplasia (HGD) and OAC. These techniques need further validation through multicentre trials
