Renal dysfunction is a key risk factor for all-cause mortality in patients with type 2 diabetes (T2D). Special attention has been raised regarding the role of soluble tumor necrosis factor receptor1 (sTNFR1) and brain natriuretic peptide (BNP) in diabetic nephropathy (DN) since they play a crucial role in the pathogenesis of T2D complications. Elevated concentrations of sTNFR1and BNP were found to be associated with progression to end stage renal disease (ESRD) in T2D. We determined serum levels of sTNFR1 and BNP in T2D patients and correlated them with various clinical variables especially kidney function and urinary albumin creatinine ratio (UACR)...

NYX-2925, a new chemical entity, acts as a co-agonist to glutamate at the N-methyl-D-aspartate receptor (NMDAR). At low concentrations of endogenous agonists (glycine/D-serine), NYX-2925 partially activates NMDARs, modulating neural pathways relevant for chronic pain. NYX-2925 is being developed for the treatment of chronic pain conditions, including painful diabetic peripheral neuropathy and fibromyalgia. In this first-in-human, Phase 1, single- (50-1200 mg) and multiple-ascending dose (150-900 mg) study, the safety, tolerability, and pharmacokinetics of NYX-2925 were evaluated in 84 healthy adult volunteers...

We thank Hersant and colleagues for their interest in our work [1]. Our study was principally designed to address the utility of clinical examination and adjunctive tests to exclude peripheral artery disease (PAD) in people with diabetes-related foot ulceration. We emphasize the importance of a negative likelihood ratio (and sensitivity) throughout because a missed diagnosis has potentially more severe consequences. This article is protected by copyright.

Affecting 9.5% of the population, diabetes represents a major health threat in China. Although age-specific incidence estimates are essential for the prevention and management of diabetes from the public health perspective and have been investigated among populations in several regions, there are no estimates for Chinese people in the literature. We therefore conducted a study to estimate the age-specific diabetes incidence among men and women in China using a secondary data analysis. This article is protected by copyright...

Amyloid fibrillation is associated with several human maladies, such as Alzheimer's, Parkinson's, Huntington's diseases, prions, amyotrophic lateral sclerosis, and type 2 diabetes diseases. Gaining insights into the mechanism of amyloid fibril formation and exploring novel approaches to fibrillation inhibition are crucial for preventing amyloid diseases. Here, we hypothesized that ligands capable of stabilizing the native state of query proteins might prevent protein unfolding, which, in turn, may reduce the propensity of proteins to form amyloid fibrils...

Metformin, an anti-diabetic drug, possesses anti-inflammatory property beyond its glucose-lowering activity, but its regulatory effect on mast cells and allergic responses remains unknown, wherein the aryl hydrocarbon receptor (AhR)-ligand axis is critical in controlling mast cell activation. Herein, we provide evidence supporting the role of metformin in modulating mast cell activation by FcεR1-, AhR-mediated signaling or their combination. Metformin at relatively low doses was shown to suppress FcεR1-mediated degranulation, IL-13, TNF-α and sphingosine-1-phosphate (S1P) secretion in murine bone marrow-derived mast cells (BMMCs)...
