Computational protein design (CPD) is a powerful technique to engineer existing proteins or to design novel ones that display desired properties. Rosetta is a software suite including algorithms for computational modeling and analysis of protein structures and offers many elaborate protocols created to solve highly specific tasks of protein engineering. Most of Rosetta's protocols optimize sequences based on a single conformation (i. e. design state). However, challenging CPD objectives like multi-specificity design or the concurrent consideration of positive and negative design goals demand the simultaneous assessment of multiple states...

This study investigated the influence of the addition of soy products on the microbiology, nutritional and physico-chemical characteristics of garri, a fermented cassava product. Malted soy flour (MSF) and soy protein (SP) were separately added (12% w/w) to cassava mash prior to controlled fermentation, while non-supplemented cassava mash served as a control. Identification of lactic acid bacteria (LAB) and aerobic mesophilic bacteria was accomplished by repetitive sequence based (rep)-PCR analysis and 16S rRNA gene sequencing...

The Médecins Sans Frontières (MSF) ethics review board (ERB) has been solicited in an unprecedented way to provide advice and review research protocols in an 'emergency' mode during the recent Ebola epidemic. Twenty-seven Ebola-related study protocols were reviewed between March 2014 and August 2015, ranging from epidemiological research, to behavioural research, infectivity studies and clinical trials with investigational products at (very) early development stages. This article examines the MSF ERB's experience addressing issues related to both the process of review and substantive ethical issues in this context...

Eulimnogammarus cyaneus and Eulimnogammarus verrucosus, closely related amphipod species endemic to Lake Baikal, differ with respect to body size (10- to 50-fold lower fresh weights of E. cyaneus) and cellular stress response (CSR) capacity, potentially causing species-related differences in uptake, internal sequestration, and toxic sensitivity to waterborne cadmium (Cd). We found that, compared to E. verrucosus, Cd uptake rates, related to a given exposure concentration, were higher, and lethal concentrations (50%; LC50) were 2...

Mediterranean spotted fever (MSF) is a rickettsiosis of the spotted fever group caused by rickettsia conorii. This zoonosis is benign but it can be complicated by severe neurological impairment (hence its severity). We report the case of a 49-year old patient hospitalized in the Department of Dermatology for rickettsiosis, who suffered from right massive hemiplegia of brutal onset. Magnetic resonance angiography (MRA) of the brain showed deep left sylvian fissure ischemic stroke. The diagnosis of conorii-type rickettsiosis has been retained based on the aspect of skin lesions and on positive sierologic testing with the indirect immunofluorescence method...

INTRODUCTION: Nigeria has one of the highest maternal mortality ratios in the world as well as high perinatal mortality. Unfortunately, the country does not have the resources to assess this critical indicator with the conventional health information system and measuring its progress toward the goal of ending preventable maternal deaths is almost impossible. Médecins Sans Frontières (MSF) conducted a cross-sectional study to assess maternal and perinatal mortality in Makoko Riverine and Badia East, two of the most vulnerable slums of Lagos...

In ecotoxicology, analytical compartmentalization analysis can be used to better understand metal sequestration and detoxification. Metals are typically found in two main compartments, biologically detoxified metal (BDM) and metal sensitive fractions (MSF). The purpose of this study was to analyze the subcellular distribution of cadmium (Cd) in Lymnaea stagnalis. Adult snails were exposed to three concentrations of Cd for 56 days as part of a global ring test for L. stagnalis. At the end of the 56-day exposure, organisms were separated in two sections (viscera and foot)...

Between August-December 2014, Ebola Virus Disease (EVD) patients from Tonkolili District were referred for care to two Médecins Sans Frontières (MSF) Ebola Management Centres (EMCs) outside the district (distant EMCs). In December 2014, MSF opened an EMC in Tonkolili District (district EMC). We examined the effect of opening a district-based EMC on time to admission and number of suspect cases dead on arrival (DOA), and identified factors associated with fatality in EVD patients, residents in Tonkolili District...

Epileptic seizures lead to aberrant hippocampal neurogenesis, including increased proliferation of neural progenitors and abnormal integrations of newly generated granule cells - hilar ectopic granule cells (EGCs), mossy fiber sprouting (MFS), and hilar basal dendrites (HBDs). Previous results from ablating hippocampal neurogenesis after acute seizures have been controversial with regards to the development of spontaneous recurrent seizures (SRSs). While ablation of hippocampal newborn cells was effective, a sufficient decrease of subsequent abnormal integrations in chronically epileptic hippocampus was not well-established in these studies...

BACKGROUND: Pushed by ongoing conflicts and pulled by the desire for a better life, over one million migrants/refugees transited Balkan countries and arrived in Europe during 2015 and early 2016. To curb this influx, European countries instituted restrictive migration policies often characterized by building of razor-wire border fences and border closures. Among migrants/refugees who received mental health care in Serbia while travelling through Balkan countries to Northern Europe, we assessed the prevalence and patterns of violent events experienced including physical trauma...

Mediterranean spotted fever (MSF) is endemic in Italy, where Rickettsia conorii subsp. conorii was thought to be the only pathogenic rickettsia and Rhipicephalus sanguineus the vector and main reservoir. R. conorii subsp. israelensis, which belongs to the R. conorii complex, is the agent of Israeli spotted fever (ISF); apart from Israel, it has also been found in Italy (Sicily and Sardinia) and in different regions of Portugal. We describe here two severe cases of ISF which occurred in otherwise healthy Italian adults...

This paper discusses the research supporting the use of multi-source feedback (MSF) for doctors and describes the mini-Peer Assessment Tool (mini-PAT), the MSF instrument currently used to assess trainees in child and adolescent psychiatry. The relevance of issues raised in the literature about MSF tools in general is examined in relation to trainees in child and adolescent psychiatry as well as the appropriateness of the mini-PAT for this group. Suggestions for change including modifications to existing MSF tools or the development of a specialty-specific MSF instrument are offered...

The Médecins Sans Frontiérs (MSF) established basic occupational health services to diagnose and treat work-related diseases among tannery, metal, plastics and garment workers and families in one of the more polluted areas of the world populated by 600 000 people. In spite of project limitations, an analysis of the 6-month data showed that of the original cohort of 5000, 3200 (64%) came for at least 1 consultation. Among them, 468 (14.6%) were diagnosed with suspected work-related diseases as per defined protocols...

Microinjection is commonly performed to achieve fish transgenesis; however, due to difficulties associated with this technique, new strategies are being developed. Here we evaluate the potential of lentiviral particles to genetically modify Nile tilapia cells to achieve transgenesis using three different approaches: spermatogonial stem cell (SSC) genetic modification and transplantation (SC), in vivo transduction of gametes (GT), and fertilised egg transduction (ET). The SC protocol using larvae generates animals with sustained production of modified sperm (80% of animals with 77% maximum sperm fluorescence [MSF]), but is a time-consuming protocol (sexual maturity in Nile tilapia is achieved at 6 months of age)...

REVIEW
Miguel Trelles Centurion, Rafael Van Den Bergh, Henry Gray
PURPOSE OF REVIEW: Disasters and armed conflicts are characterized by high numbers of trauma cases, and occur mainly in developing countries where the healthcare response is already impaired, resulting in an inadequate response. Aside of the trauma cases, other surgical health conditions are also still present and require urgent care. Surgical care needs are different from context to context and depend on local means and capabilities. RECENT FINDINGS: Doctors without Borders (MSF) has proven that even in precarious situations, safe administration of anesthesia is possible, and the "do no harm" principle can and must be upheld...
