Xavier Subirats, Laura Muñoz-Pascual, Michael H Abraham, Martí Rosés
Drugs designed to reach a pharmacological CNS target must be effectively transported across the blood-brain barrier (BBB), a thin monolayer of endothelial cells tightly attached together between the blood and the brain parenchyma. Because of the lipidic nature of the BBB, several physicochemical partition models have been studied as surrogates for the passive permeation of potential drug candidates across the BBB (octanol-water, alkane-water, PAMPA...). In the last years, biopartition chromatography is gaining importance as a noncellular system for the estimation of biological properties in early stages of drug development...

Understanding of recombination and photoconductivity dynamics of photo-generated charge carriers in GaxIn1-xP NWs is essential for their optoelectronic applications. In this paper, we have studied a series of GaxIn1-xP NWs with varied Ga composition. Time resolved photo-induced luminescence, femtosecond transient absorption and time resolved THz transmission measurements were performed to assess radiative and non-radiative recombination and photoconductivity dynamics of photo-generated charges in the NWs. We conclude that radiative recombination dynamics is limited by hole trapping whereas electrons are highly mobile until they recombine non-radiatively...

BACKGROUND: Little is known about the interaction between gender and low birth weight (LBW) and lifelong social mobility as an explanation of the etiology of obesity. The aim of the present study was to evaluate total and central obesity according to gender, LBW and social mobility, within the context of the epidemiological transition in middle-income countries. We hypothesize that there are more pronounced metabolic consequences of social mobility for women born with LBW. METHODS: We used data from a birth cohort study conducted in Ribeirão Preto, São Paulo, Brazil...

PURPOSE: T-regulatory cells (Tregs) are a sub-population of lymphocytes that act to suppress aberrant immune responses. We investigated changes in the numbers of naïve and terminally differentiated Tregs in the peripheral blood to establish their role in the immuno-suppressive response to prolonged exercise. METHODS: Blood was drawn from seventeen experienced runners (age 40 ± 12 years; height 1.75 ± 0.08 m; mass 71.4 ± 10.8 kg) before, ~1 h after (POST-1h), and on the day following the marathon (POST-1d)...

Given the importance of leukotrienes in vascular inflammation induced by local tissue injury, this study investigated the role for 5-lipoxygenase (5-LO) in monocytes in the development of intimal hyperplasia. As a mechanistic study, the importance of monocyte 5-LO in monocyte-macrophage differentiation with subsequent infiltration in neointima was evaluated. In a mouse model of wire-injured femoral artery, intimal hyperplasia started as early as 2 wks after injury, and luminal area and blood flow were reduced due to increased neointima formation...

BACKGROUND: Mobile phones are gradually becoming an integral part of healthcare services worldwide. We assessed the association between Aponjon mobile phone based messaging services and practices regarding childbirth and care of mother and neonates in selected areas in Bangladesh. METHODS: In early 2014, 476 subscriber mothers whose last born child's age was between 3 and 18 months, were recruited to the study by Dnet from selected areas of Bangladesh. One group of mothers received the early warning messages from Aponjon during pregnancy (exposed; n = 210) while the other group of new mothers did not receive the messages during pregnancy as they had enrolled in the service after childbirth (non-exposed; n = 266)...

Endogenous retroviruses are mobile genetic elements hardly distinguishable from infectious, or "exogenous," retroviruses at the time of insertion in the host DNA. Human endogenous retroviruses (HERVs) are not rare. They gave rise to multiple families of closely related mobile elements that occupy ~8% of the human genome. Together, they shape genomic regulatory landscape by providing at least ~320,000 human transcription factor binding sites (TFBS) located on ~110,000 individual HERV elements. The HERVs host as many as 155,000 mapped DNaseI hypersensitivity sites, which denote loci active in the regulation of gene expression or chromatin structure...

BACKGROUND: Personal social networks have a profound impact on our health, yet collecting personal network data for use in health communication, behavior change, or translation and dissemination interventions has proved challenging. Recent advances in social network data collection software have reduced the burden of network studies on researchers and respondents alike, yet little testing has occurred to discover whether these methods are: (1) acceptable to a variety of target populations, including those who may have limited experience with technology or limited literacy; and (2) practical in the field, specifically in areas that are geographically and technologically disconnected, such as rural Appalachian Kentucky...

Cholera epidemics have been recorded periodically in Vietnam during the seventh cholera pandemic. Since cholera is a water-borne disease, systematic monitoring of environmental waters for Vibrio cholerae presence is important for predicting and preventing cholera epidemics. We conducted monitoring, isolation, and genetic characterization of V. cholerae strains in Nam Dinh province of Northern Vietnam from Jul 2013 to Feb 2015. In this study, four V. cholerae O1 strains were detected and isolated from 110 analyzed water samples (3...

BACKGROUND: Information on physical and mental wellness in renal transplantation is limited. Therefore, we performed a cross-sectional study to evaluate and describe the different components of physical performance and quality of life (QoL) in a cohort of kidney-transplanted patients. METHODS: Physical performance and QoL were determined through the administration of validated tests and questionnaires [muscle strength, dynamometer handgrip, tactile sensitivity, visual analogue scale (VAS) for pain, Timed Up and Go (TUG) test, Fatigue Severity Scale (FSS) and the 36-item Short Form Health Survey]...

The long-term consequences of early life nicotine exposure are poorly defined. Approximately 8-10% of women report smoking during pregnancy, and this may promote aberrant development in the offspring. To this end, we investigated potential enduring effects of perinatal nicotine exposure on murine sleep and affective behaviors in adulthood (~13-15 weeks of age) in C57Bl6j mice. Mothers received a water bottle containing 200 µg/ml nicotine bitartrate dihydrate in 2% w/v saccharin or pH-matched 2% saccharin with 0...

Background: Accumulating evidence suggests that neuroinflammation plays a critical role in early brain injury after subarachnoid hemorrhage (SAH). Pannexin-1 channels, as a member of gap junction proteins located on the plasma membrane, releases ATP, ions, second messengers, neurotransmitters, and molecules up to 1 kD into the extracellular space, when activated. Previous studies identified that the opening of Pannexin-1 channels is essential for cellular migration, apoptosis and especially inflammation, but its effects on inflammatory response in SAH model have not been explored yet...

INTRODUCTION: Deep vein thrombosis (DVT) following total knee arthroplasty (TKA) and its associated complication, pulmonary thromboembolism (PTE) remains a challenge for orthopedic surgeons. There are wide ranges of predisposing factors which are both patient specific as well as procedure associated, responsible for DVT. PTE is a well-known fatal complication of DVT which may be life-threatening. Medical management and early mobilization are necessary for the management of DVT. Fatal PTE can be prevented by implantation of inferior vena cava (IVC) filter in at risk patients...

Partial tibial plateau fractures may occur as a consequence of either valgus or varus trauma combined with a rotational and axial compression component.High-energy trauma may result in a more complex and multi-fragmented fracture pattern, which occurs predominantly in young people. Conversely, a low-energy mechanism may lead to a pure depression fracture in the older population with weaker bone density.Pre-operative classification of these fractures, by Müller AO, Schatzker or novel CT-based methods, helps to understand the fracture pattern and choose the surgical approach and treatment strategy in accordance with estimated bone mineral density and the individual history of each patient...
