Inflammation has been shown to play an important role in the mechanisms involved in the pathogenesis of hypertension. Connexins (Cxs)-based gap junction channels (GJCs) or hemichannels (HCs) are involved in the maintenance of homeostasis in the immune system. However, the role of Cx43-based channels in T-lymphocytes in mediating the immune response in essential hypertension is not fully understand. The present study was designed to investigate the role of Cxs-based channels in T lymphocytes in the regulation of hypertension-mediated inflammation...

Monte Carlo simulations have been used to analyze oxygenation-related signal changes in pass-band balanced steady state free precession (bSSFP) as well as in gradient echo (GE) and spin echo (SE) sequences. Signal changes were calculated for artificial cylinders and neurovascular networks acquired from the mouse parietal cortex by two-photon laser scanning microscopy at 1 μm isotropic resolution. Signal changes as a function of vessel size, blood volume, vessel orientation to the main magnetic field B0 as well as relations of intra- and extravascular and of micro- and macrovascular contributions have been analyzed...

Managing patients with erectile dysfunction (ED) who failed to respond to phosphodiesterase type 5 inhibitors (PDE5is) is a challenging task. Recently, low-intensity extracorporeal shockwave therapy (LI-ESWT) was reported to improve ED by enhancing perfusion of the penis. The current study was performed to evaluate whether combined treatment with LI-ESWT and PDE5is can restore erectile function in patients who failed to respond to PDE5is alone. This was an open-label single-arm prospective study. ED patients with an erection hardness score (EHS) ≦2 under a maximal dosage of PDE5is were enrolled...

Hepatocellular carcinoma (HCC) is a complex disease most commonly arising in the background of chronic liver disease. In the past two decades there has been a significant increase in our understanding of both the clinical and molecular heterogeneity of HCC. There has been a robust increase in clinical trial activity in patients with poor prognostic factors such as macrovascular invasion and extrahepatic spread. We aimed to synthesize the evidence for the treatment of patients with advanced HCC based on these baseline characteristics including patients with both Child-Pugh scores of A and B...

In the present study, the spread of Rhizoctonia solani-induced disease was limited when cucumber plants were pretreated with Trichoderma atroviride TRS25. The systemic disease suppression was related to TRS25-induced resistance (TISR) induction with simultaneous plant growth promotion. Protection of cucumber was related to enhanced activity of defense enzymes, e.g., guaiacol peroxidase (GPX), syringaldazine peroxidase (SPX), phenylalanine ammonia lyase (PAL), and polyphenol oxidase (PPO) as well as phenolic (PC) concentration increases in the conditions of hydrogen peroxide (H2O2) accumulation, resulting in thiobarbituric acid reactive substance (TBARS) decrease...

BACKGROUND: After one episode of exertional heat stroke (EHS), risk factors must be identified to determine the potential for subsequent episodes. One of these risk factors, core body temperature (Tco) kinetics during strenuous exercise, may be a surrogate marker suggestive of impaired thermoregulation. This study aimed to determine the kinetics of increases in Tco among military subjects who had a history of EHS. METHODS: Forty subjects (38 males, mean age 28.4 ± 4...

Parental engagement is considered elemental to successful outcomes for parents and their children in early childhood home visiting programs. Engagement is that piece of parental involvement that refers to the working relationship between the parent and the home visitor. Multiple papers have called for research to pinpoint the ways in which home visitors work with parents to form these working relationships, and form partnerships to achieve positive outcomes. Analysis revealed that in individualizing their efforts to each family, home visitors follow semi-sequential steps in implementing engagement...

Microencapsulation of cells is beneficial for various biomedical applications, such as tissue regeneration and cell delivery. While a variety of techniques can be used to produce microspheres, electrohydrodynamic spraying (EHS) has shown promising results for the fabrication of cell-laden hydrogel microspheres in a wide range of sizes and in a relatively high-throughput manner. Here we describe an EHS technique for the fabrication of cell-laden polyethylene glycol (PEG) microspheres. We utilize mild hydrogel gelation chemistry and a combination of EHS parameters to allow for cell microencapsulation with high efficiency and viability...

Dendritic localization and hence local mRNA translation contributes to synaptic plasticity in neurons. Staufen2 (Stau2) is a well-known neuronal double-stranded RNA-binding protein (dsRBP) that has been implicated in dendritic mRNA localization. The specificity of Stau2 binding to its target mRNAs remains elusive. Using individual-nucleotide resolution CLIP (iCLIP), we identified significantly enriched Stau2 binding to the 3'-UTRs of 356 transcripts. In 28 (7.9%) of those, binding occurred to a retained intron in their 3'-UTR The strongest bound 3'-UTR intron was present in the longest isoform of Calmodulin 3 (Calm3L ) mRNA Calm3L 3'-UTR contains six Stau2 crosslink clusters, four of which are in this retained 3'-UTR intron...

AIMS/HYPOTHESIS: We have previously shown that oxidative stress plays a causal role in beta cell dysfunction induced by fat. Here, we address whether the proinflammatory kinase inhibitor of (nuclear factor) κB kinase β (IKKβ), which is activated by oxidative stress, is also implicated. METHODS: Fat (oleate or olive oil) was infused intravenously in Wistar rats for 48 h with or without the IKKβ inhibitor salicylate. Thereafter, beta cell function was evaluated in vivo using hyperglycaemic clamps or ex vivo in islets isolated from fat-treated rats...

Recently, a novel culture system consisting of primary hepatocytes structured over a network of endothelial cells on the Engelbreth-Holm-Swarm (EHS) gel has been reported. This in vitro liver model on the EHS gel (IVLEHS) has been shown to maintain the expression of hepatic genes and their functional activity. Moreover, the IVLEHS was more sensitive to xenobiotics than hepatocyte monocultures, suggesting the potential utility of this culture system for compound hepatotoxicity screening. However, the effect of this three-dimensional structure formation on the cellular metabolic profile of hepatocytes in the IVLEHS is not well understood...

INTRODUCTION: Ten adult patients with electromagnetic hypersensitivity underwent functional magnetic resonance imaging (fMRI) brain scans. All scans were abnormal with abnormalities which were consistent and similar. It is proposed that fMRI brain scans be used as a diagnostic aid for determining whether or not a patient has electromagnetic hypersensitivity. Over the years we have seen an increasing number of patients who had developed multi system complaints after long term repeated exposure to electromagnetic fields (EMFs)...

Implementation of evidence-based interventions in "real-world" settings is enhanced when front-line staff view the intervention as acceptable, appropriate, and feasible. This qualitative study addresses Early Head Start (EHS) home visitors' perceptions and experiences of an evidence-based parenting intervention, the Attachment and Biobehavioral Catch-up program (M. Dozier, O. Lindhiem, & J. Ackerman, 2005), when added to EHS services as usual within the context of a research-practice partnership. Thematic analysis of in-depth, qualitative interviews indicates that home visitors experienced the intervention as positive and helpful for EHS families...
