Biosurfactants or microbial surfactants are surface-active biomolecules that are produced by a variety of microorganisms. Biodegradability and low toxicity have led to the intensification of scientific studies on a wide range of industrial applications for biosurfactants in the field of the environmental bioremediation as well as the petroleum industry and the enhanced oil recovery. However, the major bottlenecks in biosurfactant production are yield increase and cost reduction. Improving the bioindustrial production processes relies on many issues such as the use of cheap raw materials, the optimization of medium-culture conditions and selecting hyperproducing strains...

BACKGROUND: In various countries, the association of lower hospital volume and higher mortality after oesophageal, gastric, pancreatic and rectal cancer resection has been clearly demonstrated. However, scientific evidence regarding the volume-outcomes relationship for high-risk visceral surgical procedures in Switzerland is lacking. The a priori hypothesis of this retrospective population-based cohort study analysis was that low-volume hospitals in Switzerland have a higher rate of postoperative mortality after oesophageal, gastric, pancreatic and rectal cancer resection...

Social and ecological systems come together during the act of fishing. However, we often lack a deep understanding of the fishing process, despite its importance for understanding and managing fisheries. A quantitative, mechanistic understanding of the opportunities fishers encounter, the constraints they face, and how they make decisions within the context of opportunities and constraints will enhance the design of fisheries management strategies to meet linked ecological and social objectives and will improve scientific capacity to predict impacts of different strategies...

A wealth of scientific literature has been devoted to understanding what factors influence parents and their adolescent children to obtain the HPV vaccine. This literature is relatively uniform in its methodological approach of sampling individuals (i.e., either parents or adolescents) and examining the predictors of uptake for that individual. To improve understanding of HPV vaccination uptake, we sampled low-income, African American parent-child dyads with either a female (n = 93) or a male (n = 116) adolescent who had not been vaccinated...

A number of new crops have been developed that address important traits of particular relevance for smallholder farmers in Africa. Scientists, policy makers, and other stakeholders have raised concerns that the approval process for these new crops causes delays that are often scientifically unjustified. This article develops a real option model for the optimal regulation of a risky technology that enhances economic welfare and reduces malnutrition. We consider gradual adoption of the technology and show that delaying approval reduces uncertainty about perceived risks of the technology...

Vernonia fastigiata is a multi-purpose nutraceutical plant with interesting biological properties. However, very little is known about its phytochemical composition and, thus the need for its phytochemical characterization. In the current study, an environmentally friendly method, pressurized hot water extraction (PHWE), was used to extract metabolites from the leaves of V. fastigiata at various temperatures (50 °C, 100 °C, 150 °C and 200 °C). Ultra-high performance liquid chromatography-quadrupole time of flight mass spectrometry (UHPLC-qTOF-MS) analysis in combination with chemometric methods, particularly principal component analysis (PCA) and liquid/gas chromatography mass spectrometry (XCMS) cloud plots, were used to descriptively visualize the data and identify significant metabolites extracted at various temperatures...

Background: Most pregnancy-related medical complications appear to resolve at delivery or shortly thereafter. Common examples are preterm labor, placental abruption, preeclampsia, and gestational diabetes. Women who developed such complications are known to be at increased risk of developing similar complications in future pregnancies. It has recently become evident that these women are at an increased risk of long term medical complications. Methods: A search through scientific publications in English regarding the association of obstetric complications and long-term maternal illness...

Meera Nair, Sardul Singh Sandhu, Anil Kumar Sharma
BACKGROUND: Induced Pluripotent Stem Cell (IPSC) Technology is the most advanced research as it offers an attractive alternative for establishing patient-specific IPSCs to recapitulate phenotypes of not only monogenic diseases (viz. Thalassaemia, Sickle cell anemia, Haemophilia, Tay-Sachs disease), but also late-onset polygenic diseases (viz. Parkinson's disease, Alzheimer's disease, schizophrenia). Over the hindsight, numerous studies of the past and current scientists have led to the production, maturation and understanding of induced pluripotent stem cell technology and its use in basic and clinical research...

Natural products (NPs) are secondary metabolites produced and used by organisms for defending or adapting purposes. These molecules were naturally selected during thousands of years to improve the specificity and cover a very wide range of functions, depending on the origin, the habitat and the specific activity carried out in the organism of origin. Due to these intrinsic features, NPs have been used as healing agents since thousands of years and still today continue to be the most important source of new potential therapeutic preparations...

Georgia Christodoulou, David S Black
PURPOSE OF REVIEW: The purpose of our critical examination is to present results and provide a synthesis of this body of work. RECENT FINDINGS: Sleep problems among cancer survivors are gaining research attention. To our knowledge, there have been six randomized control trials published from 2013 to 2015 that test the effects of mindfulness-based interventions (MBIs) on sleep as a primary or secondary outcome. Our examination of the literature highlights important methodological issues and variability among trials...

Prof. Shoji Shibata (1916-2016) left behind remarkable achievements in the field of the history of pharmacy. Among those, the scientific survey on medicines preserved in Shōsō-in, globally known as the World Cultural Heritage, is of particular interest, drawing wide attention from scholars to the general public. Its most spectacular and also shocking study in the field of pharmacognosy will be the one on the true origin of Kōboku (Houpu) that seems quite ordinary from its name. Prof. Shibata revealed that it is of juglandaceous origin that is completely different from what is known today under the same name...

We describe the development of the first digital atlas of the normal squirrel monkey brain and present the resulting product, VALiDATe29. The VALiDATe29 atlas is based on multiple types of magnetic resonance imaging (MRI) contrast acquired on 29 squirrel monkeys, and is created using unbiased, nonlinear registration techniques, resulting in a population-averaged stereotaxic coordinate system. The atlas consists of multiple anatomical templates (proton density, T1, and T2* weighted), diffusion MRI templates (fractional anisotropy and mean diffusivity), and ex vivo templates (fractional anisotropy and a structural MRI)...

BACKGROUND: Sexual response is the result of a complex interaction of psychological, physiological, interpersonal, social and cultural factors. Those factors - as well as sexual behavior - are subject to permanent change. OBJECTIVES: In this study, we investigated how the growth of basic knowledge and constantly changing social-cultural conditions impact the scientific definition of sexual dysfunctions, which controversies exist and to what degree these changes counteract the common tendencies of medicalization and stigmatization of sexual difficulties...
