Mexico is a megadiverse country that has 3,600 to 4,000 species of medicinal plants, of which approximately 800 are used to treat conditions related to diabetes mellitus (DM). DM is a chronic degenerative disease of energy metabolism that exists as two types: type 1 (DM1) and type 2 (DM2). DM is considered a public health problem that affects 7% of the Mexican population older than 20 years. DM is clinically controlled with hypoglycaemic drugs, alpha-glucosidase inhibitors, insulin secretion stimulants or the direct application of insulin...

Brominated flame retardants (BFRs) are organobromine compounds with an inhibitory effect on combustion chemistry tending to reduce the flammability of products. Concerns about health effects and environmental threats have led to phase-out or restrictions in the use of Penta-, Octa- and Deca-BDE technical formulations, increasing the demand for Novel BFRs (NBFRs) as replacements for the banned formulations. This study examined the occurrence of legacy and NBFRs in the dust from the interior of private cars in Thessaloniki, Greece, aged from 1 to 19 years with variable origin and characteristics...

Trehalose is a well-known protein stabilizing osmolyte. The present study has been designed to understand the interaction of trehalose with BSA at ambient temperature. Steady state fluorescence and life-time analysis along with CD, DLS and ITC have been employed to show that trehalose causes surface-associated structural perturbation of BSA to promote its compaction. Trehalose at 0.1M concentration resulted in increased solvent exposure of one of the two tryptophans of BSA with a 5nm redshift in emission and enhanced susceptibility to acrylamide quenching with an increase in KSV from 2...

Platelet-derived growth factor receptor alpha (PDGFRα), a tyrosine kinase receptor, is up-regulated in hepatic stellate cells (HSCs) during chronic liver injury. HSCs mediate hepatic fibrosis through their activation from a quiescent state partially in response to pro-fibrotic growth factors. HSC activation entails enhanced expression of pro-fibrotic genes, increase in proliferation, and increase in motility, which facilitates migration within the hepatic lobule. We show co-localization of PDGFRα in murine carbon tetrachloride, bile duct ligation (BDL), and 0...

BACKGROUND: The objective of this study was to update and analyze tuberculosis (TB) mortality data in the European Union between 2000 and 2010 separately for men and women and try to detect if there have been any changes in trends in each country and the association with the economic situation and inequalities. METHODS: Data were extracted for tuberculosis deaths in 2000-2010 for 29 European Union countries and for Switzerland, via the World Health Organization (WHO) European detailed mortality database (DMDB), using the Mortality tabulation list 1 (MTL1) codes for men and women separately for one age group (20-85+)...

T-cell based vaccines have been considered as attractive candidates for prevention of hepatitis C virus (HCV) infections. In this study we compared the magnitude and phenotypic characteristics of CD8+ T-cells induced by three commonly used viral vectors, Adenovirus-5 (Ad5), Vaccinia virus (VV) and Modified Vaccinia Ankara (MVA) expressing the HCV NS3/4A protein. C57/BL6 mice were primed with DNA expressing NS3/4A and boosted with each of the viral vectors in individual groups of mice. We then tracked the vaccine-induced CD8+ T-cell responses using pentamer binding and cytokine production analysis...

BACKGROUND: Carboxylesterases (CCEs) are one of three large detoxification enzyme families. Some CCEs are active on synthetic insecticides with ester structures. Anopheles sinensis is an important malaria vector in eastern Asia. This study identified and characterized the CCE genes in the An. sinensis genome and determined CCE genes associated with pyrethroid resistance using RNA-seq and RT-qPCR, in An. sinensis from Anhui, Chongqing, and Yunnan in China. RESULTS: Fifty-seven putative CCEs were identified and placed into 3 classes, 12 subfamilies and 14 clades through phylogenetics and homology analyses...

INTRODUCTION: Stem cell therapy for acute myocardial infarction (AMI) seemed to be a promising therapy, however large clinical trials brought differential outcome. It has been shown that paracrine effects of secretomes of stem cells rather than cell therapy might play a fundamental role. The present study sought to compare cell processing protocols of clinical trials and investigated effects of differential cell culture conditions on chemokine secretion and functional effects. METHODS: Different secretomes were compared regarding IL-8, VEGF, MCP-1 and TNF-alpha secretion...

Alpha-synuclein (α-Syn) overexpression and misfolding/aggregation in degenerating dopaminergic neurons have long been implicated in Parkinson's disease (PD). The neurotoxicity of α-Syn is enhanced by iron (Fe) and other pro-oxidant metals, leading to generation of reactive oxygen species in PD brain. Although α-Syn is predominantly localized in presynaptic nerve terminals, a small fraction exists in neuronal nuclei. However, the functional and/or pathological role of nuclear α-Syn is unclear. Following up on our earlier report that α-Syn directly binds DNA in vitro, here we confirm the nuclear localization and chromatin association of α-Syn in neurons using proximity ligation and chromatin immunoprecipitation analysis...

The aim of the present study was to investigate the role of microRNA (miR)‑21 in regulating collagen I and Smad7 expression in activated rat hepatic stellate cells (HSCs). Rat HSCs were isolated by single‑step density gradient centrifugation with Nycodenz. Cellular content of miR‑21, SMAD7, α‑smooth muscle actin (α‑SMA), collagen type I alpha 1 (COLLA1) and COLL alpha 2 (A2) mRNA was examined by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR), and cellular content of Smad7 and α‑SMA protein was detected by western blotting...

Fabricio Rocha Vieira, John Andrew Pecchia
Substrate preparation (i.e., composting) for Agaricus bisporus cultivation is the most critical point of mushroom production. Among many factors involved in the composting process, the microbial ecology of the system is the underlying drive of composting and can be influenced by composting management techniques. Pasteurization temperature at the beginning of phase II, in theory, may influence the bacterial community and subsequently the "selectivity" and nutrition of the final substrate. Therefore, this hypothesis was tested by simulation in bioreactors under different pasteurization conditions (57 °C/6 h, 60 °C/2 h, and 68 °C/2 h), simulating conditions adopted by many producers...

Amotosalen and ultraviolet A photochemical-based pathogen reduction using the InterceptTM Blood System is an effective and established technology for platelet and plasma components, which is adopted in more than 40 countries worldwide. Several reports point towards a reduced platelet function after Amotosalen/UVA exposure. The current study was undertaken to identify the mechanisms responsible for the early impairment of platelet function by the InterceptTM Blood System. Twenty-five platelet apheresis units were collected from healthy volunteers following standard procedures and split into 2 components, one untreated and the other treated with Amotosalen/UVA...

Parents play an important role in supporting school functioning in youth with chronic pain, but no validated tools exists to assess parental responses to child and adolescent pain behaviors in the school context. Such a tool would be useful in identifying targets of change to reduce pain-related school impairment. The goal of this study was to develop and preliminarily validate the Parent Responses to School Functioning (PRSF) Questionnaire, a parent self-report measure of this construct. After initial expert review and pilot testing, the measure was administered to 418 parents of children (ages 6-17) seen for initial multidisciplinary chronic pain clinic evaluation...

Boron neutron capture therapy (BNCT) is a binary therapy that employs neutron irradiation on the boron agents to release high-energy helium and alpha particles to kill cancer cells. An optimal response to BNCT depends critically on the time point of maximal (10)B accumulation and highest tumor to normal ratio (T/N) for performing the neutron irradiation. The aggressive cholangiocarcinoma (CCA) representing a liver cancer that overexpresses COX-2 enzyme is aimed to be targeted by COX-2 selective boron carrier, fenbufen boronopinacol (FBPin)...
