Cyclosporin has had a major impact on organ transplantation, but associated nephrotoxicity is a significant problem. Renal hypothermia, a known anti-ischemic maneuver, limits cyclosporin-ischemic renal failure. Pharmacological manipulation with an anti-ischemic agent, such as trimetazidine, may prevent cyclosporin nephrotoxicity. We tested this hypothesis in a canine single kidney model of cyclosporin-enhanced ischemic renal failure. Trimetazidine treatment was associated with significantly better biochemical and histological markers of renal function and structure. Trimetazidine may have a role to play in protecting against cyclosporin nephrotoxicity in clinical renal transplantation.

Spinal microglia and astrocytes are both involved in neuropathic and inflammatory pain, which may display sexual dimorphism. Here, we demonstrate that the sustained activation of spinal astrocytes and astrocyte-derived interleukin (IL)-17A promotes the progression of mouse bone cancer pain without sex differences. Chemogenetic or pharmacological inhibition of spinal astrocytes effectively ameliorates bone cancer-induced pain-like behaviors.

Aging is a complex process characterized by biological decline and a wide range of molecular alterations to cells, including changes to DNA methylation. In this study, we used a male-specific epigenetic marker of aging to build an epigenetic predictor that measures long-term androgen exposure in sheep and mice (median absolute error of 4.3 and 1.

Background: Modulation of protein synthesis according to the physiological cues is maintained through tight control of Eukaryotic Elongation Factor 2 (eEF2), whose unique translocase activity is essential for cell viability. Phosphorylation of eEF2 at its Thr56 residue inactivates this function in translation. In our previous study we reported a novel mode of post-translational modification that promotes higher efficiency in T56 phosphorylation.

Bruxism is a significant phenomenon that should not be underestimated, given its prevalence and consequences. The major symptoms associated with bruxism include myalgia, decreased quality of life, and limited mandibular movements. This study aimed to evaluate and compare the effectiveness of four treatment methods for managing bruxism-related symptoms: botulinum toxin (BoNT-A), dry needling (DN), pharmacological therapy (PT), and manual therapy (MT).

Background: Streptomyces roseochromogenes NRRL 3504 produces clorobiocin, an aminocoumarin antibiotic that inhibits DNA replication. No other natural products have been isolated from this bacterium so far, despite the presence of a rich repertoire of specialized metabolite biosynthesis gene clusters (smBGCs) within its genome. Heterologous expression of smBGCs in suitable chassis speeds up the discovery of the natural products hidden behind these sets of genes.
