Chromium(III) has generally been considered to be essential for proper carbohydrate and lipid metabolism, and, despite recent evidence to the contrary, chromium(III)-containing compounds remain one of the most popular commercial dietary supplements. Cr3, or [Cr3O(O2CCH2CH3)6(H2O)3]NO3·H2O, is a trivalent chromium compound that is a promising chromium nutritional supplement. Studies with Cr3 have indicated that it is non-toxic in developmental and short- and long-term exposure studies in rodents, but the safety of this compound to chromosomes and cells has not been explored...

Ixolaris is a two-Kunitz tick salivary gland protein identified in Ixodes scapularis that presents sequence homology to TFPI (tissue factor pathway inhibitor). It binds to the coagulation enzyme factor Xa (FXa) or to its zymogen form, FX, and further inhibits tissue factor/FVIIa complex (extrinsic Xnase compex). Differently from TFPI, Ixolaris does not bind to the active site cleft of FXa. Instead, complex formation is mediated by the FXa heparin-binding exosite, which may also results in decreased FXa activity into the prothrombinase complex...

The anticoagulant effect of rivaroxaban, a direct inhibitor of activated factor X (FX), might be influenced by its dosing time because the activity of the coagulofibrinolytic system exhibits daily rhythmicity. In rats, FX activity follows a 24-h rhythm with a peak in the middle of the light phase and a trough at the beginning of the dark phase. Consistent with these findings, a single dose of rivaroxaban had a stronger inhibitory effect on FX activity after dosing at the beginning of the light phase than after dosing at the beginning of the dark phase...

BACKGROUND: The importance of QoL and neurocognitive functions in patients with glioblastoma (GB) is above controversy by now. We followed newly diagnosed GB patients treated with radio-chemotherapy during their course of disease by continuously evaluating their quality of life (QoL) and cognitive functions. METHODS: We included consecutive patients with newly diagnosed GB from 2010 to 2013 at the Medical University of Vienna. To assess QoL the EORTC QLQ C30 and BN20 questionnaire were used...

During blood-coagulation, the transmembrane protein tissue factor (TF) binds to its ligand, factor (F)VII, activating and allosterically modifying it to form a mature active binary complex (TF-FVIIa). Although the extracellular domain of TF (sTF) can bind to FVII, it fails to activate it. Binding of TF with FVIIa only partially enhances FVIIa proteolytic activity. Our previous kinetic study revealed that sTF has a lower binding capacity with FVIIa compared to membrane bound full-length (fl)TF. The reason behind this incapability of FVII activation and reduced catalytic activity remains unexplored due to the lack of an flTF crystal structure...

BACKGROUND: Multiple trauma is frequently associated with hemorrhagic shock and fractures of the extremities. Clinically, the rate of impaired fracture healing (delayed healing and nonunion) seems to be increased in patients with multiple injuries compared with patients with isolated fractures. As the underlying pathogenesis remains poorly understood, we aimed to analyze the biomechanical properties during fracture healing in a murine model. QUESTIONS: The aim of this study was to determine whether fracture healing after severe hemorrhagic shock results in (1) delayed bridging as determined by macroscopic and radiographic assessment, (2) altered conditions of callus components as determined by µCT, and (3) decreased maximum bending moment measured by a three-point-bending test compared with ordinary fracture healing...

The few data available on fusarenon-X (FX) do not support the derivation of health-based guidance values, although preliminary results suggest higher toxicity than other regulated trichothecenes. Using histo-morphological analysis and whole transcriptome profiling, this study was designed to obtain a global view of the intestinal alterations induced by FX. Deoxynivalenol (DON) served as a benchmark. FX induced more severe histological alterations than DON. Inflammation was the hallmark of the molecular toxicity of both mycotoxins...

Non-muscle-invasive bladder cancer (NMIBC) is a heterogeneous disease with widely different outcomes. We performed a comprehensive transcriptional analysis of 460 early-stage urothelial carcinomas and showed that NMIBC can be subgrouped into 3 major classes with basal- and luminal-like characteristics and different clinical outcomes. Large differences in biological processes such as the cell cycle, epithelial-mesenchymal transition, and differentiation were observed. Analysis of transcript variants revealed frequent mutations in genes encoding proteins involved in chromatin organization and cytoskeletal functions...

BACKGROUND: Factor X (FX) binds to cell membranes in a highly phospholipid-dependent manner and, in complex with tissue factor and factor VIIa (FVIIa), initiates the clotting cascade. Experimental information concerning the membrane-bound structure of FX with atomic resolution has remained elusive due to the fluid nature of cellular membranes. FX is known to bind preferentially to phosphatidylserine (PS). OBJECTIVES: To develop the first membrane-bound model of FX-GLA domain to PS at atomic level, and to identify PS-specific binding sites of FX-GLA domain...

BACKGROUND: Thalamic deep brain stimulation (DBS) is an effective strategy for the treatment of essential tremor (ET). With limitations of imaging modalities, targeting largely relies on indirect methods. This study was designed to determine the optimal target for DBS in ET and construct a targeting method based on probabilistic maps. METHODS: Patients with ET who had sustained tremor reduction at 1-year and optimal microelectrode recordings were selected. Stimulation volume was individually modeled in standard space and a final optimal region was derived for the whole population...

Excessive mRNA translation downstream of group I metabotropic glutamate receptors (mGlu1/5) is a core pathophysiology of fragile X syndrome (FX); however, the differentially translating mRNAs that contribute to altered neural function are not known. We used translating ribosome affinity purification (TRAP) and RNA-seq to identify mistranslating mRNAs in CA1 pyramidal neurons of the FX mouse model (Fmr1(-/y)) hippocampus, which exhibit exaggerated mGlu1/5-induced long-term synaptic depression (LTD). In these neurons, we find that the Chrm4 transcript encoding muscarinic acetylcholine receptor 4 (M4) is excessively translated, and synthesis of M4 downstream of mGlu5 activation is mimicked and occluded...

BACKGROUND AND OBJECTIVE: The use of pulsed dye laser (PDL) and fractional CO2 (FX CO2 ) laser therapy to treat and/or prevent scarring following burn injury is becoming more widespread with a number of studies reporting reduction in scar erythema and pruritus following treatment with lasers. While the majority of studies report positive outcomes following PDL or FX CO2 therapy, a number of studies have reported no benefit or worsening of the scar following treatment. The objective of this study was to directly compare the efficacy of PDL, FX CO2 , and PDL + FX CO2 laser therapy in reducing scarring post burn injury and autografting in a standardized animal model...

Fucoxanthinol (FuOH), an intestinal metabolite form of fucoxanthin (Fx) isolated from marine algae, is known to possess multiple health benefits, such as prevention of human cancer. However, there is little available information about the effects of FuOH on colorectal cancer stem cells (CCSCs) and their contribution to drug resistance, tumorigenesis and cancer recurrence. In the present study, we investigated the anti-proliferative effect of FuOH on two putative CCSCs, CD44(high)/EpCAM(high) cells and colonospheres (Csps) formed by HT-29 human colorectal cancer cells, and the suppressive effects of FuOH on the growth of xenografted tumor...
