Human recombinant vasostatin-1 may interfere with cell-extracellular matrix interactions

2006

Vasostatin-1 (VS-1), the N-terminal fragment derived from the cleavage of chromogranin A (CgA), has been shown to exert several biological activities on several tissues and organs. Recently, it has been reported that human recombinant VS-1 (STA-CGA(1-78)) may alter myocardial contractility in eel, frog., and rat hearts. In this article we have explored if STA-CGA(1-78) can induce intracellular cascades interacting both with adhesion molecules and/or extracellular matrix (ECM), components, that is, involvement of the heat shock protein 90 (HSP90) and the endothelial NOS (eNOS), known to be implicated in signal transduction mechanisms affecting myocardial contractility. We used 3D cultured ad…

Background Arabidopsis thaliana copper metallochaperone CCH is a functional homologue of yeast antioxidant ATX1, involved in cytosolic copper transport. In higher plants, CCH has to be transported to specialised cells through plasmodesmata, being the only metallochaperone reported to date that leaves the cell where it is synthesised. CCH has two different domains, the N-terminal domain conserved among other copper-metallochaperones and a C-terminal domain absent in all the identified non-plant metallochaperones. The aim of the present study was the biochemical and biophysical characterisation of the C-terminal domain of the copper metallochaperone CCH.

New antihyperglycaemic agents and cardiovascular disease: let's be optimistic.

2018

Cardiovascular disease (CVD) substantially increases mortality in diabetes mellitus. This narrative review highlights recent research on the putative associations between dipeptyl peptidase 4 inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium glucose co-transporter 2 inhibitors (SGLT-2is) and several cardiovascular risk factors.New antihyperglycaemic agents favourably modulate several CVD risk factors, including fasting and postprandial plasma glucose levels, body weight, blood pressure, lipids, microalbuminuria, nonalcoholic fatty liver disease, serum uric acid, and arterial stiffness. Liraglutide (in LEADER), semaglutide (in SUSTAIN-6), empagliflozin (in EMPA-REG …

The subtle solubility of water in n-decane causes leaking of the droplet content. If the n-decane flows by static droplets, it carries the water slowly away up to the total disappearance of the droplets.

Tooth size discrepancy in a Libyan population, a cross-sectional study in schoolchildren

2014

Objetives: The aim of this cross-sectional study was to investigate the tooth size discrepancy (TSD) in a group of Libyan schoolchildren, and to compare TSD between sexes. Material and Methods: The sample comprised 333 Libyan schoolchildren (162 males with a mean (SD) age of 14.4 (1.1) years, and 171 females with a mean age of 14.1 (1.1) years). Anterior and overall TSD ratios were computed using descriptive statistics. Sex differences were statistically assessed using an independent t-test ( P 0.05). The percentages of participants showing more than 2 SD variation for the anterior and overall ratios comprised 3% and 4.2% of the total sample, respectively. Conclusions: The anterior and over…

Thyroid Stimulating Hormone Receptor Antibodies in Thyroid Eye Disease-Methodology and Clinical Applications.

2018

Background Thyroid stimulating hormone receptor antibodies (TSHR-Ab) cause autoimmune hyperthyroidism and are prevalent in patients with related thyroid eye disease (TED). Purpose To provide a historical perspective on TSHR-Ab and to present evidence-based recommendations for clinical contemporary use. Methods The authors review the recent literature pertaining to TSHR-Ab in patients with TED and describe the various immunoassays currently used for detecting TSHR-Ab and their clinical applications. Results We provide a historical summary and description of the various methods used to detect TSHR-Ab, foremost, the functional TSHR-Ab. Increasing experimental and clinical data demonstrate the …

Magnetic separation of encapsulated islet cells labeled with superparamagnetic iron oxide nano particles.

2012

Islet cell transplantation is a promising option for the restoration of normal glucose homeostasis in patients with type 1 diabetes. Because graft volume is a crucial issue in islet transplantations for patients with diabetes, we evaluated a new method for increasing functional tissue yield in xenogeneic grafts of encapsulated islets. Islets were labeled with three different superparamagnetic iron oxide nano particles (SPIONs; dextran-coated SPION, siloxane-coated SPION, and heparin-coated SPION). Magnetic separation was performed to separate encapsulated islets from the empty capsules, and cell viability and function were tested. Islets labeled with 1000 μg Fe/ml dextran-coated SPIONs expe…

Bioassays for TSH Receptor Antibodies: Quo Vadis?

2015

Autoantibodies (Ab) to the TSH receptor (TSHR) are responsible for many of the clinical manifestations of Graves' disease (GD) and are specific biomarkers of this autoimmune thyroid disorder (AITD) [1,2,3]. These Ab can be measured either via competitive-binding immunoassays or with bioassays [4]. Antibody-binding assays only report the presence or absence of TSHR-Ab and their concentrations, but do not indicate their functional activity. Bioassays, in contrast, indicate whether TSHR-Ab have stimulatory or blocking activity [5]. Historically, bioassays for TSHR-Ab were research tools used to study the pathophysiology of GD. Recently, however, there are increasing data that demonstrate the c…
