Antibacterial and osteogenic gain strategy on titanium surfaces for preventing implant-related infections.

Colloids Surf B Biointerfaces

December 2024

College of Chemical Engineering, Xinjiang Normal University, 102 Xinyi Road, Urumqi 830054, P.R. China. Electronic address:

Infection and insufficient osseointegration are the primary factors leading to the failure of titanium-based implants. Surface coating modifications that combine both antibacterial and osteogenic properties are commonly employed strategies. However, the challenge of achieving rapid antibacterial action and consistent osteogenesis with these coatings remains unresolved.

Maternal Low-Protein Diet During Nursing Leads to Glucose-Insulin Dyshomeostasis and Pancreatic-Islet Dysfunction by Disrupting Glucocorticoid Responsiveness in Male Rats.

Biology (Basel)

December 2024

Research Group on Perinatal Programming of Metabolic Diseases: DOHaD Paradigm, Laboratory of Metabolic and Cardiovascular Diseases, Health Education and Research Center (NUPADS), Institute of Health Sciences, Federal University of Mato Grosso, University Campus of Sinop, Sinop 78556-264, Brazil.

Both perinatal malnutrition and elevated glucocorticoids are pivotal triggers of the growing global pandemic of metabolic diseases. Here, we studied the effects of metabolic stress responsiveness on glucose-insulin homeostasis and pancreatic-islet function in male Wistar offspring whose mothers underwent protein restriction during lactation. During the first two weeks after delivery, lactating dams were fed a low-protein (4% protein, LP group) or normal-protein diet (22.

Article Synopsis
  • The study investigates the effects of Tongfu Xiefei Guanchang Solution (TFXF) on acute lung injury (ALI) in rats, focusing on improving intestinal health through a specific signaling pathway.
  • Sixty SPF-grade Wistar rats are divided into groups receiving different treatments, including control, LPS, dexamethasone, and various doses of TFXF, with ALI induced by LPS injection.
  • Results demonstrate that TFXF treatment improves lung and colon tissue conditions by reducing inflammation markers like TNF-α and IL-1β and positively altering intestinal flora composition.

Lonafarnib Protects Against Muscle Atrophy Induced by Dexamethasone.

J Cachexia Sarcopenia Muscle

February 2025

Department of Nanobiomedical Science & BK21 NBM Global Research Center for Regenerative Medicine, Dankook University, Cheonan, Korea.

Background: Muscle atrophy, including glucocorticoid-induced muscle wasting from treatments such as dexamethasone (DEX), results in significant reductions in muscle mass, strength and function. This study investigates the potential of lonafarnib, a farnesyltransferase inhibitor, to counteract DEX-induced muscle atrophy by targeting key signalling pathways.

Methods: We utilized in vitro models with C2C12 myotubes treated with DEX and in vivo models with Caenorhabditis elegans and DEX-treated Sprague-Dawley rats.
