CB1 and TRPV1 receptors may have opposite roles in modulating neural activity and, consequently, in regulating the stress response. These receptors are widely expressed in several brain structures, including the ventral medial pre-frontal cortex (vmPFC). The functional consequences of the interaction between CB1 and TRPV1, however, have scarcely been explored. Therefore, we investigated if CB1 and TRPV1 receptors located in the vmPFC would be involved in the behavioral changes induced by the stress of the forced swim test (FST)...

Abiraterone acetate (AA) demonstrated its efficacy in the treatment of patients with metastatic castration resistance prostate cancer (mCRPC) in predocetaxel and postdocetaxel setting. However, we learn from pivotal studies that forms of primary and acquired resistance to this drug exist. Patient selection becomes so crucial to optimize treatment results. Potential predictive biomarkers have been identified but are not yet validated. In this scenario, clinical features and disease characteristics may still be of value in selecting patients for different treatments...

Bone loss is a critical pathology responsible for the functional disability in patients with rheumatoid arthritis (RA). It is well known that receptor activator of nuclear factor kappa-B (NF-κB) ligand (RANKL) plays a crucial role in bone loss in RA. The purpose of this study was to determine whether recombinant human endostatin (rh-endostatin) mediates bone erosion in RA by regulation of RANKL expression in an experimental model of RA, consisting of mice with adjuvant-induced arthritis (AA). Cultured AA fibroblast-like synoviocytes (FLSs) obtained from these mice were induced by tumor necrosis factor-α (TNF-α) combined with or without rh-endostatin...

l-Tryptophan (TRP) is metabolized via serotonin and kynurenine pathways (KP). Several studies have demonstrated that abnormality of both pathways is involved in the pathogenesis of major depressive disorder (MDD). Kynurenine 3-monooxygenase (KMO), a pivotal enzyme in the KP, has been suggested to play major roles in physiological and pathological events mediated by bioactive kynurenine metabolites. In this study, we investigated the role of KMO in the emotional and cognitive functions by using KMO knockout (KO) mice...

Polymorphisms at genes encoding proteins involved in the pathogenesis of psoriasis (Psor) or in the mechanism of action of biological drugs could influence the treatment response. Because the interleukin (IL)-17 family has a central role in the pathogenesis of Psor, we hypothesized that IL17RA variants could influence the response to anti-TNF drugs among Psor patients. To address this issue we performed a cross-sectional study of Psor patients who received the biological treatments for the first time, with a follow-up of at least 6 months...

It remains a challenge to synthesize Ag nanocubes in an aqueous system although the polyol process has been successfully adopted more than one decade ago. Here we report an aqueous method for the synthesis of Ag nanocubes with an average edge length of 35-95 nm. It involves the formation of AgCl octahedra by mixing CF3COOAg with cetyltrimethylammonium chloride (CTAC), followed by the nucleation and growth of Ag nanocrystals in the presence of ascorbic acid (AA) and FeCl3. The Fe(3+)/Fe(2+) redox pair is responsible for the removal of multiply twinned seeds through oxidative etching...

Increased myostatin expression, resulting in muscle loss, has been associated with hyperammonemia in mammalian models of cirrhosis. However, there is evidence that hyperammonemia in avian embryos results in a reduction of myostatin expression, suggesting a proliferative myogenic environment. The present in vitro study examines species differences in myotube and liver cell response to ammonia using avian and murine-derived cells. Primary myoblasts and liver cells were isolated from embryonic day 15 and 17 chick embryos to be compared with mouse myoblasts (C2C12) and liver (AML12) cells...

BACKGROUND: Amyloidosis has been a mystery for centuries, but research of the last decennia has clarified many of the secrets of this group of diseases. A protein-based classification of amyloidosis helps to understand problems that were part of the obsolete clinical classification in primary, secondary, and familial amyloidosis. All types of amyloid are secondary to some underlying precursor-producing process: each type is caused by a misfolded soluble precursor protein that becomes deposited as insoluble amyloid fibrils...
