Unlabelled: is well adapted to survive and persist in the infected host, escaping the host's immune response. Since polyamines such as spermine, which are synthesized by infected macrophages, are able to inhibit the growth of , the pathogen needs strategies to cope with these toxic metabolites. The actinomycete , a close relative of makes use of a gamma-glutamylation pathway to functionally neutralize spermine.

Adverse drug reactions (ADR) remain a challenge in modern healthcare, particularly given the increasing complexity of therapeutics. WHO's definition of an adverse drug reaction as a response to a drug that is noxious and unintended and occurs at doses normally used in man for the prophylaxis, diagnosis or therapy of disease, or for modification of physiological function. This definition underscores the importance of monitoring and mitigating unintended drug effects, particularly for widely used medications like valproic acid (VPA).

Plants have evolved complex mechanisms to cope with diverse abiotic stresses, with the phenylpropanoid pathway playing a central role in stress adaptation. This pathway produces an array of secondary metabolites, particularly polyphenols, which serve multiple functions in plant growth, development, regulating cellular processes, and stress responses. Recent advances in understanding the molecular mechanisms underlying phenylpropanoid metabolism have revealed complex regulatory networks involving MYB transcription factors as master regulators and their interactions with stress signaling pathways.

The liver, a major organ involved in substance metabolism, is highly susceptible to toxicity induced by chemicals and their metabolites. Although damage-associated molecular patterns (DAMPs) have been implicated in the development of sterile inflammation following cell injury, their involvement in chemically induced hepatocellular injury remains underexplored. This study aimed to determine the role of high-mobility group box 1 (HMGB1), a DAMP, in a rat model of liver injury treated with thioacetamide, a hepatotoxicant.

Liquid biopsy is gaining importance in oncology in the age of precision medicine. Extracellular vesicles (EVs), among other tumor-derived indicators, are isolated and analysed from bodily fluids. EVs are secreted by both healthy and cancerous cells and are lipid bilayer-enclosed particles that are diverse in size and molecular makeup.
