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 (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.

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.

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.

The composition of marine mammal blubber is influenced by factors such as diet and environmental conditions. Here, we investigate the thermal influence on fatty acid composition and degree of unsaturation in the blubber of 151 South American sea lions (Otaria byronia). Samples were collected at ten locations along the Chilean coast and spanned a latitudinal range of approximately 2500 km, an arc of 23°.
