Short thymic stromal lymphopoietin (short TSLP), one of TSLP variants, exerts anti-inflammatory activities in endotoxin shock and colitis mouse models. Our latest work reported that short TSLP prevented house dust mite (HDM)-induced epithelial barrier disruption. Yet the role of short TSLP in toluene diisocyanate (TDI)-induced asthma is unknown. Male BALB/c mice were sensitized and challenged with TDI to generate a chemical-induced asthma model. Synthetic short TSLP peptides were given intranasally (i.n.) or intraperitoneally (i...

Advanced glycation end products (AGEs) and oxidative stress are elevated with aging and dysmetabolic conditions. Because a Mediterranean (Med) diet reduces oxidative stress, serum AGEs levels, and gene expression related to AGEs metabolism in healthy elderly people, we studied whether supplementation with coenzyme Q10 (CoQ) was of further benefit. Twenty participants aged ≥ 65 (10 men and 10 women) were randomly assigned to each of three isocaloric diets for successive periods of 4 weeks in a crossover design: Med diet, Med + CoQ, and a Western high-saturated-fat diet (SFA diet)...

BACKGROUND: In the past, elevated estradiol levels were reported to downregulate the iron regulatory hormone hepcidin, thereby potentially improving iron metabolism. As estrogen plays a role in regulating the menstrual cycle and can influence the cytokine interleukin-6 (IL-6; a hepcidin up-regulator), this investigation examined the effects of estradiol supplementation achieved by the use of a monophasic oral contraceptive pill (OCP) on IL-6, hepcidin levels and iron status during the hormone-deplete versus hormone-replete phases within an oral contraceptive cycle (OCC)...

Osteoma cutis is a condition characterized by theformation of bone within the skin. Such aberrantossification of the skin and subcutaneous tissue isconsidered primary when it arises in the absence ofunderlying tissue damage or a preceding cutaneouslesion. Conversely, secondary osteoma cutis occurswhen skin ossification is the result of a pre-existingskin lesion, trauma, or inflammatory process [1,2].Although rare, primary osteoma cutis has beenassociated with a number of different geneticdisorders. Albright hereditary osteodystrophy (AHO),a condition first described in 1942 by Fuller Albright,is an autosomal dominant metabolic disorder causedby a mutation in the GNAS1 gene [3]...

Clarification of the interaction mechanisms between proteins and bioactive components is important to develop effective carriers for encapsulation and protection of bioactive components. Bovine serum albumin (BSA), a globular protein in serum and milk, contains multiple sites to bind a variety of low-molecular-weight molecules, forming protein-mono-ligand complexes. In this study, the interactions of BSA with retinol, resveratrol and/or (-)-epigallocatechin-3-gallate (EGCG) were investigated by using fluorescence, circular dichroism and molecular docking techniques...

Background.: Human infection by orthopoxviruses is being reported with increasing frequency, attributed in part to the cessation of smallpox vaccination and concomitant waning of population-level immunity. In July 2015, a female resident of interior Alaska, presented to an urgent care clinic with a dermal lesion consistent with poxvirus infection. Laboratory testing of a virus isolated from the lesion confirmed infection by an Orthopoxvirus. Methods.: The virus isolate was characterized by using electron microscopy and nucleic acid sequencing...

Aims: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is characterized by fibrofatty infiltration of the myocardium and ventricular arrhythmias that may lead to sudden cardiac death. It has been observed that male patients develop the disease earlier and present with more severe phenotypes as compared to females. Thus, we hypothesized that serum levels of sex hormones may contribute to major arrhythmic cardiovascular events (MACE) in patients with ARVC/D. Methods and results: The serum levels of five sex hormones, sex hormone-binding globulin, high sensitivity troponin T, pro-brain natriuretic peptide, cholesterol, triglycerides, insulin, and glucose were measured in 54 ARVC/D patients (72% male)...

Towards addressing the need for novel alternatives to antibiotics, we attempted to sensitize Gram-negative bacilli (GNB) to innate antibacterial protagonists. We report a lipopeptide-like sequence (C10OOc12O) that inflicted outer-membrane damages at low micromolar range, whereas measurable bacterial growth inhibition in broth medium required >10-fold higher concentrations. In serum however, C10OOc12O induced antibacterial activity in a manner suppressible by anti-complements antibodies or heat treatment, and acted synergistically with exogenous lysozyme in broth and serum media...

To avoid aortic cross-clamping and cardioplegic ischaemia, we propose the induction of hyperkalemic arrest and using aortic no-touch technique in minimally invasive atrial septal defect (ASD) closure. Twenty-eight patients were included in this study. After establishment of cardiopulmonary bypass, potassium was administered to induce hyperkalemic arrest. The mean dose of injected potassium was 1.2 ± 0.45 mEq/kg. Following the direct closure of the ASD, potassium was filtered out using a hemodialyzer. At the end of the operation, serum potassium was normalized to 4...

Background.: The conventional 2-tiered serologic testing protocol for Lyme disease (LD), an enzyme immunoassay (EIA) followed by immunoglobulin M and immunoglobulin G Western blots, performs well in late-stage LD but is insensitive in patients with erythema migrans (EM), the most common manifestation of the illness. Western blots are also complex, difficult to interpret, and relatively expensive. In an effort to improve test performance and simplify testing in early LD, we evaluated several modified 2-tiered testing (MTTT) protocols, which use 2 assays designed as first-tier tests sequentially, without the need of Western blots...
