Clinical Results of Carpal Tunnel Release Using Ultrasound Guidance in Over 100 Patients at Two to Six Years.

Purpose: The purpose of this study was to determine the clinical results of carpal tunnel release using ultrasound guidance (CTR-US) at a minimum of 2 years postprocedure.

Methods: The study consisted of 102 patients (162 hands) treated with CTR-US by the same physician between June 2017 and October 2020 for whom minimum 2-year follow-up data were available. Questionnaires were sent to gather long-term information, with additional phone calls for clarification if needed.

Apoptotic β-cells induce macrophage reprogramming under diabetic conditions.

Type 2 diabetes mellitus (T2DM) occurs when insulin-producing pancreatic β-cells fail to secrete sufficient insulin to compensate for insulin resistance. As T2DM progresses, apoptotic β-cells need to be removed by macrophages through efferocytosis that is anti-inflammatory by nature. Paradoxically, infiltrating macrophages are a main source of inflammatory cytokines that leads to T2DM.

Stigmasterol prevents glucolipotoxicity induced defects in glucose-stimulated insulin secretion.

Type 2 diabetes results from defects in both insulin sensitivity and insulin secretion. Elevated cholesterol content within pancreatic β-cells has been shown to reduce β-cell function and increase β-cell apoptosis. Hyperglycemia and dyslipidemia contribute to glucolipotoxicity that leads to type 2 diabetes.

Multifunctional in vivo imaging of pancreatic islets during diabetes development.

Pancreatic islet dysfunction leading to insufficient glucose-stimulated insulin secretion triggers the clinical onset of diabetes. How islet dysfunction develops is not well understood at the cellular level, partly owing to the lack of approaches to study single islets longitudinally in vivo Here, we present a noninvasive, high-resolution system to quantitatively image real-time glucose metabolism from single islets in vivo, currently not available with any other method. In addition, this multifunctional system simultaneously reports islet function, proliferation, vasculature and macrophage infiltration in vivo from the same set of images.

Regulation of adipocyte differentiation and gene expression-crosstalk between TGFβ and wnt signaling pathways.

Obesity results in reduced differentiation potential of adipocytes leading to adipose tissue insulin resistance. Elevated proinflammatory cytokines from adipose tissue in obesity, such as TNFα have been implicated in the reduced adipocyte differentiation. Other mediators of reduced adipocyte differentiation include TGFβ and wnt proteins.

Biglycan deletion alters adiponectin expression in murine adipose tissue and 3T3-L1 adipocytes.

Obesity promotes increased secretion of a number of inflammatory factors from adipose tissue. These factors include cytokines and very lately, extracellular matrix components (ECM). Biglycan, a small leucine rich proteoglycan ECM protein, is up-regulated in obesity and has recently been recognized as a pro-inflammatory molecule.
