1. The aim of this study was to investigate the effects on the rectal temperature of young chickens of the oral administration of a medium that contained both live bacteria that produce D-aspartate (D-Asp) and D-Asp. 2. In Experiment 1, chickens were subjected to chronic oral administration of either the medium (containing live bacteria and 2.46 μmol D-Asp) or water from 7 to 14 d of age. Plasma-free amino acids as well as mitochondrial biogenic gene expression in the breast muscle were analysed. In Experiment 2, 7-d-old chickens were subjected to acute oral administration of the above medium or of an equimolar amount of D-Asp to examine their effect on changes in rectal temperature...

Depression currently affects 350 million people worldwide and 19 million Americans each year. Women are 2.5 times more likely to experience major depression than men, with some women appearing to be at a heightened risk during the menopausal transition. Estrogen signaling has been implicated in the pathophysiology of mood disorders including depression; however, the underlying mechanisms are poorly understood. In this study, the role of estrogen receptor (ER) subtypes, ERα and ERβ, in the regulation of brain-derived neurotrophic factor (BDNF) and serotonin (5-HT) signaling was investigated; two pathways that have been hypothesized to be interrelated in the etiology of depression...

Tuberculosis (TB) is still a major global threat, killing more than one million persons each year. With the constant increase of Mycobacterium tuberculosis strains resistant to first- and second-line drugs, there is an urgent need for the development of new drugs to control the propagation of TB. Although screenings of small molecules on axenic M. tuberculosis cultures were successful for the identification of novel putative anti-TB drugs, new drugs in the development pipeline remains scarce. Host-directed therapy may represent an alternative for drug development against TB...

Serotonin [5-hydroxytryptamine (5-HT)] is an important neuromodulator involved in a wide range of physiological functions. The effects of serotonin are mediated by an extended family of receptors coupled to multiple heterotrimeric G-proteins, associated with cellular membrane. G proteins connect receptors to effectors and thus trigger intracellular signaling pathways. These cellular processes several regulate systemic functions such as embryonic development, gonadal development, learning and memory, and organismal homeostasis...

Furanodienone, a major bioactive constituents of sesquiterpene derived from Rhizoma Curcumae, has been proven to possess the potent anticancer efficacy on human breast cancer cells. Here, we investigated the cytotoxicity of furanodienone on human colorectal carcinoma cell lines in vitro and in vivo, as well as its underlying molecular mechanisms in the induction of apoptosis. In this study, we found that furanodienone significantly inhibited proliferation of RKO and HT-29 cells, induced mitochondrial dysfunction characterized by collapse of mitochondrial transmembrane potential and reduction of ATP level, and promoted the production of reactive oxygen species (ROS) that functions upstream of caspase-dependent apoptosis...

A combinatorial synthetic methodology based on evaporation sources in ultra-high vacuum has been used to directly synthesise compositional gradient thin film libraries of the amorphous phases of GeSbTe alloys at room temperature over a wide compositional range. An optical screen is described which allows the rapid parallel mapping of the amorphous to crystalline phase transition temperature, and the optical contrast associated with the phase change, on such libraries. The results are shown to be consistent with the literature for compositions where published data are available along the Sb2Te3-GeTe tie line...

The interactions between fatty acids (FA) classes: polyunsaturated (PUFA-ω6, PUFA-ω3), saturated (SFA), EPA (eicosapentaenoic acid-ω3), DHA (docosahexaenoic-ω3) and cardiometabolic syndrome (CMS) clusters, thrombosis development and vascular inflammation are subtle. This relationship is mediated by insulin resistance (IR), endothelial dysfunction, platelet aggregation disorder and atherosclerosis. OBJECTIVES: We investigated whether PUFA/SFA - PUFA-ω6/PUFA-ω3 ratios and EPA + DHA can be associated with predictive atherothrombogenic biomarkers status in type 2 diabetes (T2D) patients with or without hypertension (HT)...

Poly(ADP-ribose)polymerase1 (PARP1) is an important enzyme in regulating DNA replication. Inhibition of PARP1 can lead to collapsed DNA forks which subsequently causes genomic instability, making DNA more susceptible in developing fatal DNA double strand breaks. PARP1-induced DNA damage is generally repaired by homologous recombination (HR), in which BRCA2 proteins are essential. Therefore, BRCA2-deficient tumour cells are susceptible to treatment with PARP1-inhibitors (PARP1-i). Recently, BRCA2 was shown to be down-regulated by hyperthermia (HT) temporarily, and this consequently inactivated HR for several hours...

PURPOSE: We introduce a method for calculation of the ultimate specific absorption rate (SAR) amplification factors (uSAF) in non-uniform body models. The uSAF is the greatest possible SAF achievable by any hyperthermia (HT) phased array for a given frequency, body model and target heating volume. METHODS: First, we generate a basis-set of solutions to Maxwell's equations inside the body model. We place a large number of electric and magnetic dipoles around the body model and excite them with random amplitudes and phases...

RESUMEN Diseases like diabetes mellitus (DM) and hypertension (HT) generate high costs and are the most common cause of mortality in the Americas. In the case of Peru, given demographic and epidemiological changes, particularly the alarming increase in overweight and obesity, the burden of these diseases is constantly increasing, resulting in the need to budget more financial resources to the health services. The total care costs of these diseases and their complications represent a financial burden that should be considered very carefully by health institutions when they draft their budgets...
