BACKGROUND: To perform a comparative effectiveness analyses between enzalutamide and abiraterone acetate in both the pre-docetaxel and post-docetaxel settings based on published phase III randomized trials. METHODS: The primary measure of efficacy was the posterior probability that enzalutamide outperforms abiraterone acetate (AA) with prednisone in terms of overall survival (OS) on average. Indirect meta-estimates were generated from four randomized studies in the context of a Bayesian hierarchical model with study-specific efficacy estimates meta-analyzed on the log scale...

: Cyclic GMP-AMP synthase (cGAS) is a newly identified DNA sensor that recognizes foreign DNA, including the genome of herpes simplex virus 1 (HSV-1). Upon binding of viral DNA, cGAS produces cyclic GMP-AMP, which interacts with and activates stimulator of interferon genes (STING) to trigger the transcription of anti-viral genes such as type I interferons and production of inflammatory cytokines. HSV-1 UL24 is widely conserved among the herpesviruses family and is essential for efficient viral replication...

Non-small cell lung cancer (NSCLC) is the most common cancer globally. The XRCC1 protein interacts with ligase and poly(ADP-ribose) polymerase to repair cisplatin-induced DNA damage. The authors of previous studies have reported XRCC1 Arg399Gln, Arg280His, and Arg194Trp polymorphisms and advanced NSCLC prognosis, but the results are inconclusive. We investigated the association between clinical outcome and XRCC1 Arg399Gln, Arg280His, and Arg194Trp polymorphisms in advanced NSCLC patients treated with cisplatin...

Crocin and crocetin in rat plasma were simultaneously analysed using ultra-performance liquid chromatography tandem mass spectroscopy (UPLC-MS/MS), and method was fully validated. For the first time, levels of both crocin and crocetin in plasma were profiled after oral administration of crocin, and this UPLC-MS/MS approach was applied to evaluate pharmacokinetics and relative bioavailability of crocin and crocetin in rats. It was shown that crocin transformed into crocetin quickly in the gastrointestinal tract, and crocetin was 56-81 fold higher exposed in rat plasma than crocin after oral administration of crocin...

PURPOSE: Currently, we cannot predict an individual patient's response to a given radiotherapy which normally is not detected for weeks to months post-treatment. As a result, precious time is wasted for patients with unresponsive tumors who could have switched to an alternative treatment much earlier. Presently, no early treatment response detection method exists that is effective, low-cost, non-invasive, and safe. We hypothesize that changes in tumor microvasculature predict tumor response to radiotherapy earlier than tumor volume changes...

The objective of the study was to explore the extent to which the dietary CP level can be reduced for maintaining muscle protein deposition in growing pigs as well as the related mechanism and whether the response to dietary protein restriction is diversely modified throughout the 2 trial periods. A total of 36 pigs (9.57 ± 0.64 kg initial BW) were individually penned and fed 1 of 3 diets for 10 or 25 d. During each period, the diets contained 20, 17, and 14% CP, respectively. Both the 17% CP diet and the 14% CP diet were supplemented with Lys, Met, Thr, and Trp to provide the same total concentrations as those in the 20% CP diet...

BACKGROUND: Hypertension (HTN), which is a major risk factor for cardiovascular morbidity and mortality, can drive pathologic remodeling of the macro- and microcirculation. Patterns of aortic pathology differ, however, suggesting regional heterogeneity of the pressure-sensitive protease systems triggering extracellular matrix remodeling in the thoracic (TA) and abdominal aortas (AA). This study tested the hypothesis that the expression of two major protease systems (matrix metalloproteinases [MMPs] and cathepsins) in the TA and AA would be differentially affected with HTN...

BACKGROUND: Platelet dysfunction has been described as an early component of trauma induced coagulopathy (TIC). The platelet component of TIC remains to be fully elucidated and translatable animal models are required to facilitate mechanistic investigations. We sought to determine if the early platelet dysfunction described in trauma patients could be recapitulated in an non-human primate (NHP) model of poly-traumatic hemorrhagic shock. METHODS: Twenty-four male Rhesus Macaques weighting 7-14 kilograms were subjected to 60 minutes (min) severe pressure-targeted controlled hemorrhagic shock (HS) with and without other injuries...

Background: Children and adolescents with at-risk genotypes (AA/AT) of the rs9939609 polymorphism in FTO, a fat mass and obesity-associated gene, may exhibit different cardiometabolic profile responses than subjects with the TT genotype after an interdisciplinary intervention. Methods: The sample consisted of 36 school children from southern Brazil. We used DNA quantitation and real-time polymerase chain reaction (PCR) for polymorphism genotyping. We measured anthropometric parameters (body mass index (BMI), waist circumference, hip circumference, waist-hip ratio, body fat percentage and skinfold sum), biochemical parameters (glucose, lipid profile, ultra-sensitive C-reactive protein, uric acid, alanine aminotransferase, aspartate aminotransferase, insulin and adiponectin) and blood pressure...

AIM: Hypoxia-inducible factor (HIF) contributes to the adaptation of tumor cells to hypoxic conditions, so genetic polymorphisms involved in this pathway may affect cellular response to hypoxia and be associated with cancer risk. Thus, we examined the association between the lung cancer risk and genetic polymorphisms involved in the HIF pathway. METHODS: This case-control study consists of 462 lung cancer cases and 379 controls from Japan. We examined the effect of HIF1A rs11549467, HIF1A rs11549465, HIF1A rs2057482, HIF2A rs13419896 and vascular endothelial growth factor A (VEGFA) rs833061 on the risk of lung cancer using TaqMan real-time PCR assay...

The angiogenic pathway plays a pivotal role in tumor growth, invasiveness and metastasis. The most important actors in the angiogenic pathway are VEGFA and its receptors VEGFR1, 2 and 3. These genes are polymorphic, and the presence of single nucleotide polymorphisms may result in angiogenic deregulation. Herein, we hypothesized that germline variants may affect sunitinib efficacy (TTP and OS) and/or toxicity. Therefore, we investigated 19 polymorphisms, in four genes, in 54 GIST patients, treated with second-line sunitinib and 147 healthy controls...
