Gut microbiome shifts in adolescents after sleeve gastrectomy with increased oral-associated taxa and pro-inflammatory potential

Gut Microbes
Bariatric surgery is highly effective in achieving weight loss in children and adolescents with severe obesity, however the underlying mechanisms are incompletely understood, and gut microbiome changes are unknown.

Vertical sleeve gastrectomy reverses diet-induced gene-regulatory changes impacting lipid metabolism

Scientific Reports, 2017
Vertical sleeve gastrectomy (VSG) produces sustainable weight loss, remission of type 2 diabetes (T2D), and improvement of nonalcoholic fatty liver disease (NAFLD).

Constrained operation zone of a VSG considering the DC-side power margin

The Journal of Engineering, 2019
Recently, the virtual synchronous generator (VSG) has drawn considerable attention for its function of simulating the electromechanical transient of SG to make converters equip with the characters of inertia, damping, voltage regulating, and frequency ...

An allele-selective inter-chromosomal protein bridge supports monogenic antigen expression in the African trypanosome

Nature Communications, 2023
UPF1-like helicases play roles in telomeric heterochromatin formation and X-chromosome inactivation, and also in monogenic variant surface glycoprotein (VSG) expression via VSG exclusion-factor-2 (VEX2), a UPF1-related protein in the African trypanosome.

Experienced Weight Stigma Changes Following Bariatric Surgery: a Systematic Review and Meta‐Analysis

Obesity Reviews, Volume 27, Issue 9, September 2026.
ABSTRACT Background Experiencing weight stigmatization is linked to maladaptive eating, poorer mental health, and increased risk of weight gain, potentially impacting metabolic bariatric surgery (MBS) outcomes. This meta‐analysis aimed to synthesize patient experiences of weight stigmatization before and after MBS and to examine the association of ...

Comparative Evaluation of Structure–Processing–Property Relationships in Flax, Hemp, and Cattail Discontinuous fiber Thermoset Composites

Polymer Composites, Volume 47, Issue 15, Page 13910-13926, 10 August 2026.
Needle punching reorients fibers from in‐plane direction toward z‐direction of the web, resulting in mechanical interlocking of fibers and reduction in the nonwoven mat thickness. ABSTRACT Replacement of glass fiber mats, utilized in large and complex composite parts in the transportation industry, with natural fiber mats requires knowledge of natural ...

A Parameter-Adaptive Method for Primary Frequency Regulation of Grid-Forming Direct-Drive Wind Turbines

Sensors
When wind turbines contribute to system frequency support using virtual synchronous generator (VSG) control, conventional VSG methods often fall short of meeting operational demands, particularly in terms of inertia and frequency support.

Glycemic Normalization Immediately Following Vertical Sleeve Gastrectomy in Adolescents With Type 2 Diabetes From the ST2OMP Study

Diabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 7555-7561, August 2026.
ABSTRACT Aim Youth‐onset type 2 diabetes and obesity are rising public health burdens. While newer type 2 diabetes medications lower HbA1c, their impact on paediatric weight loss is inconsistent. In contrast, bariatric surgery improves glycemia and weight in youth and adults, though glycemia post‐vertical sleeve gastrectomy (VSG), now the predominant ...

Primary cilia–extracellular vesicle crosstalk in Alzheimer's disease: Emerging mechanisms and biomarker potential

Alzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract Alzheimer's disease (AD) is a neurodegenerative condition marked by cognitive decline and synaptic issues. Recent studies show primary cilia (PCs), sensory organelles present on the surface of most mammalian cells, act as a critical regulators of brain homeostasis and signaling.
