Thymus mitochondria play a crucial role in immune function. This study identifies the novel protective role of N-Acetylglucosamine (NAG) in dexamethasone (DEX) induced mitochondrial perturbations in mice thymus. Mice were induced with DEX (5mg/kg) and treated with NAG i.p. (266μg/kg, 400μg/kg and 800μg/kg) for 14 days, Withanolide A (800μg/kg) has been used as positive control. Dose dependent treatment of NAG against DEX significantly restored the mitochondrial enzyme levels (ICDH, KDH, SDH and MDH) and elevated the mitochondrial glutathione antioxidants defense (GSH, SOD, GPX and GST) thus improving the ATP status which was confirmed by ultrastructural alterations in mitochondria and nucleus using TEM studies. Further histopathological studies also revealed that NAG attenuate DEX induced thymotoxicity. Finally, the study concludes that dose dependent treatment of NAG supports a potential role in preventing DEX induced thymotoxicity and NAG acts as a beneficial pharmacological intervention in the DEX induced thymic repercussions.

Background: Dexamethasone has proven life-saving in severe acute respiratory syndrome (SARS) and COVID-19 cases. However, its systemic administration is accompanied by serious side effects. Inhalation delivery of dexamethasone (Dex) faces challenges such as low lung deposition, brief residence in the respiratory tract, and the pulmonary mucus barrier, limiting its clinical use.

Background/objectives: Glioblastoma is the most common and lethal primary brain tumor. Patients often suffer from tumor- and treatment induced vasogenic edema, with devastating neurological consequences. Intracranial edema is effectively treated with dexamethasone.

: The PreserFlo™ MicroShunt (PFMS) is a bleb-forming device considered to be less invasive than traditional glaucoma surgery such as trabeculectomy. This study evaluates the 1-year success rates as well as safety profile of PFMS in patients having high intraocular pressure (IOP) and/or glaucoma refractory to drop therapy with a history of prior intravitreal dexamethasone therapy. : A total of 16 eyes after PFMS implantation due to elevated IOP after intravitreal dexamethasone implant (DEX-I) administration were included in this retrospective cohort study.

Agomelatine is an atypical antidepressant with a long half-life and the mechanism of action similar to melatonin. Agomelatine is a strong antioxidant and its anti-inflammatory effect has been reported in many studies. The current study aimed to evaluate the anti-inflammatory effect of agomelatine loaded in targeted nanoparticles (NPs) in an experimental colitis model induced by trinitrobenzene sulfonic acid (TNBS).

Radiotherapy (RTx) is a highly effective treatment for head and neck cancer that can cause concurrent damage to surrounding healthy tissues. In cases of nasopharyngeal carcinoma (NPC), the auditory apparatus is inevitably exposed to radiation fields and sustains considerable damage, resulting in dysfunction. To date, little research has been conducted on the changes induced by RTx in the middle ear and the underlying mechanisms involved.
