Glucagon: a potential protective factor against peripheral nerve compromise in patients with type 2 diabetes and obesity.
Diabetol Metab Syndr
January 2025
Department of Endocrinology, Affiliated Hospital 2 of Nantong University, and First People's Hospital of Nantong City, No.666 Shengli Road, Nantong, 226001, China.
Background: Increased glucagon levels are now recognized as a pathophysiological adaptation to counteract overnutrition in type 2 diabetes (T2D). This study aimed to elucidate the role of glucagon in peripheral nerve function in patients with T2D with different body mass indices (BMIs).
Methods: We consecutively enrolled 174 individuals with T2D and obesity (T2D/OB, BMI ≥ 28 kg/m), and 480 individuals with T2D and nonobesity (T2D/non-OB, BMI < 28 kg/m), all of whom underwent oral glucose tolerance tests to determine the area under the curve for glucagon (AUC).
Sorafenib enhanced the function of myeloid-derived suppressor cells in hepatocellular carcinoma by facilitating PPARα-mediated fatty acid oxidation.
Mol Cancer
January 2025
Department of Radiation Oncology, Peking University Third Hospital, Beijing, 100191, China.
Background: Sorafenib, an FDA-approved drug for advanced hepatocellular carcinoma (HCC), faces resistance issues, partly due to myeloid-derived suppressor cells (MDSCs) that enhance immunosuppression in the tumor microenvironment (TME).
Methods: Various murine HCC cell lines and MDSCs were used in a series of in vitro and in vivo experiments. These included subcutaneous tumor models, cell viability assays, flow cytometry, immunohistochemistry, and RNA sequencing.
Peptide nucleic acid (PNA) clamps reduce amplification of host chloroplast and mitochondria rRNA gene sequences and increase detected diversity in 16S rRNA gene profiling analysis of oak-associated microbiota.

School of Natural Sciences, Bangor University, Bangor, UK.
Background: Acquiring representative bacterial 16S rRNA gene community profiles in plant microbiome studies can be challenging due to the excessive co-amplification of host chloroplast and mitochondrial rRNA gene sequences that reduce counts of plant-associated bacterial sequences. Peptide Nucleic Acid (PNA) clamps prevent this by blocking PCR primer binding or binding within the amplified region of non-target DNA to stop the function of DNA polymerase. Here, we applied a universal chloroplast (p)PNA clamp and a newly designed mitochondria (m)PNA clamp to minimise host chloroplast and mitochondria amplification in 16S rRNA gene amplicon profiles of leaf, bark and root tissue of two oak species (Quercus robur and Q.

BMC Health Serv Res
January 2025
Department of Engineering, University Campus Bio-Medico of Rome, Via Alvaro del Portillo 21, Rome, 00128, Italy.
Background: Oxygen therapy is critical and vital treatment for hypoxemia and respiratory distress, however, access to reliable oxygen systems remains limited in SSA. Despite WHO initiatives that distributed over 30,000 OC oxygen concentrators worldwide, SSA faces significant challenges related to their maintenance and use, due to harsh environmental conditions, technical skill shortages and inadequate infrastructure. This review aims to systematically identify and assess the literature on OC design adaptations, maintenance challenges, and knowledge gaps in SSA, providing actionable recommendations to inform innovative and context-sensitive solutions to improve healthcare delivery in the region.

J Anesth Analg Crit Care
January 2025
Department of Anesthesia and Intensive Care, Agostino Gemelli IRCCS University Polyclinic Foundation, Rome, Italy.
Background: Neuromuscular blocking agents (NMBAs) are routinely used in anesthesia practice. An undetected, incomplete recovery of neuromuscular function at the end of surgery potentially exposes patients to clinical deterioration in the postoperative period. The aim of this study was to investigate the incidence of postoperative residual neuromuscular blockade (RNMB) in a cohort of patients receiving NMBAs.
