The COVID-19 pandemic has prompted the exploration of effective treatment options, with dexamethasone emerging as a key corticosteroid for severe cases. This review evaluates the efficacy and safety of dexamethasone, highlighting its ability to reduce mortality rates, alleviate acute respiratory distress syndrome (ARDS), and mitigate hyperinflammation. While dexamethasone shows therapeutic promise, potential adverse effects-including cardiovascular issues, neuropsychiatric complications, lung infections, and liver damage-necessitate careful monitoring and individualized treatment strategies.

Dimethyl itaconate modulates neuroprotective effect on primary rat astrocytes under inflammatory condition by regulating the expression of neurotrophic factors and TrkA/B-P75 receptors.

Introduction: Astrocytes, specialized glial cells, are essential for maintaining the central nervous system homeostasis. Inflammatory conditions can disrupt neurotrophic factors and receptor expression in astrocytes, leading to potential central nervous system damage. Itaconate, recently identified for its anti-inflammatory properties, was investigated in this study for its effects on neurotrophic factors in LPS-stimulated primary rat astrocytes.

Pesticide Exposure and Its Association with Parkinson's Disease: A Case-Control Analysis.

Parkinson's disease (PD) is a complex disorder that arises from genetic and environmental factors. The current investigation endeavors to investigate the role of exposure to organochlorine (OCPs) and organophosphate pesticides (OPPs), recognized as the main environmental elements, in the genesis of PD. In this case-control study, 29 PD patients and 51 healthy subjects were involved.

Menthol as an effective inhibitor of quorum sensing and biofilm formation in Candida albicans and Candida glabrata by targeting the transcriptional repressor TUP1.

Background: Menthol, a natural quorum sensing molecule, is derived from the Mentha species. Combating pathogenicity by inactivating quorum sensing is an emerging approach. Therefore, our objective was to investigate anti-quorum sensing and anti-biofilm potentials of menthol in Candida albicans and Candida glabrata.

Nanomedicine marvels: crafting the future of cancer therapy with innovative statin nano-formulation strategies.

Statins, traditionally used for managing hyperlipidemia and cardiovascular diseases, have garnered significant interest for their potential anti-cancer properties. Research indicates that statins can inhibit critical processes in cancer development, such as apoptosis, angiogenesis, and metastasis. Despite their promising anti-cancer effects, the clinical application of statins in oncology has been hampered by their inherent low solubility and bioavailability.

Metformin boosts doxorubicin efficacy and increases CD8 + T cell frequency in mouse breast cancer.

Purpose: Breast cancer is a leading cause of cancer-related deaths among women worldwide. The presence and function of CD8 + T cells in the tumor microenvironment have been associated with better patient outcomes. Drug toxicity has posed a significant challenge to the clinical implementation of chemotherapy-based strategies in cancer treatment.
