Microprofiling real time nitric oxide flux for field studies using a stratified nanohybrid carbon-metal electrode.

Nitric oxide (NO) is an important signaling molecule that is involved in stress response, homeostasis, host defense, and cell development. In most cells, NO levels are in the femtomolar to micromolar range, with extracellular concentrations being much lower. Thus, real time measurement of spatiotemporal NO dynamics near the surface of living cells/tissues is a major challenge.

Reversal of Roux-en-Y Gastric Bypass: A Multi-Centric Analysis of Indications, Techniques, and Surgical Outcomes.

Background: Roux-en-Y gastric bypass may present long-term complications that require revisional surgery or even reversal to normal anatomy. Data on the indications, surgical technique, and outcomes of RYGB reversal remain scarce.

Methods: We identified 48 cases of RYGB reversals with complete 90-day follow-up within a multi-centric international retrospective database of elective secondary bariatric surgery.

MicroRNA-150 Deletion from Adult Myofibroblasts Augments Maladaptive Cardiac Remodeling Following Chronic Myocardial Infarction.

MicroRNA (miR: small noncoding RNA)-150 is evolutionarily conserved and is downregulated in patients with diverse forms of heart failure (HF) and in multiple mouse models of HF. Moreover, miR-150 is markedly correlated with the outcome of patients with HF. We previously reported that systemic or cardiomyocyte-derived miR-150 in mice elicited myocardial protection through the inhibition of cardiomyocyte death, without affecting neovascularization and T cell infiltration.

Cozen's phenomenon.

Purpose Of Review: The purpose of this review is to describe the current trends in the treatment of Cozen's phenomenon and evaluate if there are changes in the treatment paradigm due to the advent of implant-mediated guided growth.

Recent Findings: Current literature emphasizes the need for early recognition of Cozen's phenomenon (tibia valgus), with a high incidence associated with proximal tibia fractures. There are cases with late onset progression of the valgus deformity, which can be easily treated with implant-mediated guided growth.

Enhancement of biocompatibility of anodic nanotube structures on biomedical Ti-6Al-4V alloy via ultrathin TiO coatings.

This work aims to describe the effect of the surface modification of TiO nanotube (TNT) layers on Ti-6Al-4V (TiAlV) alloy by ultrathin TiO coatings prepared via Atomic Layer Deposition (ALD) on the growth of MG-63 osteoblastic cells. The TNT layers with two distinctly different inner diameters, namely ∼15 nm and ∼50 nm, were prepared via anodic oxidation of the TiAlV alloy. Flat, i.
