Significant changes in the proteome highlight essential metabolic adaptations for development and oxidative signaling induced by the treatment of young sugarcane plants with hydrogen peroxide. These adaptations suggest that hydrogen peroxide acts not only as a stressor but primarily as a signaling molecule, triggering specific metabolic pathways that regulate growth and plant resilience. Sugarcane is a crucial crop for sugar and ethanol production, often influenced by environmental signals.

Sarcoidosis is a rare, multisystemic disease of unknown etiology, characterized by noncaseating granulomas in various organs. The disease often presents with nonspecific symptoms that complicate the diagnosis. We describe the case of a 31-year-old woman who presented to her family doctor with weight loss, cervical lymphadenopathy, parotid edema, and cutaneous lesions, initially raising suspicion of a lymphoproliferative disorder.

Food insecurity was measured using the Household Food Insecurity Access Scale, and anthropometric measurements (weight, length/height) were taken using standard techniques.

Universal salt iodisation (USI) plays an essential role in the provision of iodine (I) to populations worldwide. Countries adopting USI programmes, adhering to strict criteria laid down by expert organisations such as the Iodine Global Network, are estimated to have reduced the prevalence of I deficiency by 75% (protecting 720 million individuals worldwide). Despite this success, doubts have been raised as to the desirability of continuing such programmes because of (a) the need to reduce salt intake for cardiovascular prevention and (b) the induction of thyroid autoimmunity.
