Irisin is a polypeptide hormone derived from the proteolytic cleavage of fibronectin-type III domain-containing 5 (FNDC5) protein. Once released to circulation upon exercise or cold exposure, irisin stimulates browning of white adipose tissue (WAT) and uncoupling protein 1 (UCP1) expression, leading to an increase in total body energy expenditure by augmented UCP1-mediated thermogenesis. It is currently unknown whether irisin is secreted by bone upon exercise or whether it regulates bone metabolism in vivo...

BACKGROUND: GABAA receptors have been implicated in the pathophysiology of depression, epilepsy and pain disorders. The purpose of this study was to investigate two novel synthetic flavones, 3'-methoxy-6-methylflavone (3'-MeO6MF) and 3'-hydroxy-6-methylflavone (3'-OH6MF), for their effect on GABAA receptors and subsequently investigate their antidepressant, anticonvulsant and antinociceptive effects. METHODS: Recombinant GABAA receptor subunits were expressed in Xenopus oocytes and a two electrode voltage clamp technique was used for electrophysiological studies...

YAP/TAZ are the major mediators of mammalian Hippo signaling; however, their precise function in the gastrointestinal tract remains poorly understood. Here we dissect the distinct roles of YAP/TAZ in endodermal epithelium and mesenchyme and find that, although dispensable for gastrointestinal epithelial development and homeostasis, YAP/TAZ function as the critical molecular switch to coordinate growth and patterning in gut mesenchyme. Our genetic analyses reveal that Lats1/2 kinases suppress expansion of the primitive mesenchymal progenitors, where YAP activation also prevents induction of the smooth muscle lineage through transcriptional repression of Myocardin...

The process parameters of the up-flow biological activated carbon filter (UBACF) were optimized in a pilot-scale trial for controlling the precursor of dichloroacetonitrile (DCAN), an emerging nitrogenous disinfection by-product. The experiments were performed using a central composite design (CCD) with the response surface methodology (RSM). The results showed that the removal efficiencies of formation potentials (FP) of DCAN increased from 28.9% to 64.4% with the optimized ozone dose, expansion rate of BAC and backwashing cycle, being scheduled to 1...

Ruizhi Pang, Kaisong Zhang
Thin film nanocomposite reverse osmosis (TFN RO) membranes incorporated with hydrophilic nanoparticles show a potential problem that the salt rejection can not be improved significantly. In this study, novel TFN RO membranes incorporated with hydrophobic fluorinated silica nanoparticles were fabricated to improve the salt rejection. Fluorinated silica nanoparticles were well dispersed in organic phase during the interfacial polymerization (IP) process. The TFN RO membranes were characterized with attenuated total reflectance infra-red, field emission scanning electron microscopy, atomic force microscopy and water contact angle measurements...

The objective of the present study was to determine whether the polycyclic aromatic hydrocarbons (PAHs) associated with the Deepwater Horizon (DWH) oil spill impacted the stress response of teleost fish. The hypothesis was that intraperitoneal (IP) treatment with PAHs associated with the DWH oil spill or waterborne exposure to DWH oil high energy water-accommodated fraction (HEWAF) would result in the downregulation of the stress response of Gulf toadfish, Opsanus beta, a benthic marine teleost fish that resides in the Gulf of Mexico...

Chronic inflammation contributes to increased mortality in hemodialysis (HD) patients. YKL-40 is a novel marker of inflammation, tissue remodeling, and highly expressed in macrophages inside vascular lesions. Elevated levels of YKL-40 have been reported for HD patients but how it integrates into the proinflammatory mediator network as a predictor of mortality remains elusive. We studied serum YKL-40, Interleukin-6 (IL-6), high-sensitivity C-reactive protein, monocyte chemotactic protein-1 (MCP-1), and interferon-gamma induced protein-10 (IP-10) in 475 chronic hemodialysis patients...

Despite theoretical support for the relationship between disclosure (or "outness") and positive health outcomes for people with concealable stigmatized identities, research using outness to predict health elicits weak to inconsistent relationships. In the current research we argue that it is the need to frequently conceal that predicts negative health consequences, rather than outness. A sample of adults recruited from Amazon's Mechanical Turk reported on mental illness, chronic physical illness, or minority sexual orientation (N = 288) concealment...

BACKGROUND: Research suggests that enhanced neural reactivity to errors, measured via the error-related negativity (ERN), is relatively unique to internalizing psychopathologies (IPs) and symptom clusters characterized by excessive worry and apprehension. However, no prior study has tested the association between the ERN and IP symptom dimensions in a heterogeneous, clinically representative patient population. The current study was designed to address this gap in the literature and clarify the role of the ERN in an adult IP treatment-seeking patient sample...

BACKGROUND: Human enucleated mature red blood cells (RBCs) contain both mature microRNAs (miRNAs) and mRNAs, and we have previously correlated RBC storage lesion processes such as eryptosis, adenosine 5'-triphosphate loss, and RBC indices with differentially expressed miRNAs. Here we have characterized Argonaute 2 (AGO2)-miRNA complexes in stored mature RBCs as a first step toward understanding their role, if any. STUDY DESIGN AND METHODS: In this report AGO2-bound miRNAs in mature RBCs isolated from RBCs collected from three different healthy donors and stored for 24 hours at 4 to 6°C were identified by anti-AGO2 immunoprecipitation (IP) followed by next-generation sequencing of the RNA isolated from the IP...

A B Riber, D A Guzman
Injurious pecking (IP) remains one of the major welfare challenges in housing of laying hens worldwide due to the negative consequences it inflicts on animal welfare and economy. One potential solution to reduce IP is the use of dark brooders as the primary heat source during rearing. The objective was to investigate effects of rearing layer chicks with different management strategies and size allowances of dark brooders on IP and production-related traits during rear and lay. Groups of 100 to 103 Isa Warren chicks were reared either with one of 4 brooder types (n = 4 per treatment) or with whole-house heating (control: n = 6)...

Incontinentia pigmenti (IP) is a rare X-linked dominant disorder, in which skin lesions distributed along Blaschko's lines appear shortly after birth. Early lesions which are erythematous/bullous evolve over time into warty lesions, hyperpigmented swirls/macules, and atrophic hypopigmented streaks. Clinical features are heterogeneous. Abnormalities of the teeth, nails, hair, eyes, central nervous system, and breast may also be present. While intelligence is generally normal, varied degrees of intellectual disability/developmental delay have been reported...

The major risk factor for Klebsiella liver abscess (KLA) is type 2 diabetes mellitus (DM), but the immunological mechanisms involved in the increased susceptibility are poorly defined. We investigated the responses of neutrophils and peripheral blood mononuclear cells (PBMCs) to hypervirulent Klebsiella pneumoniae (hvKP), the causative agent of KLA. DNA and myeloperoxidase levels were elevated in the plasma of KLA patients compared to uninfected individuals indicating neutrophil activation, but diabetic status had no effect on these neutrophil extracellular trap (NET) biomarkers in both subject groups...
