Second-generation (2G) bioethanol production, derived from lignocellulosic biomass, has emerged as a sustainable alternative to fossil fuels by addressing growing energy demands and environmental concerns. Fungal sugar transporters (STs) play a critical role in this process, enabling the uptake of monosaccharides such as glucose and xylose, which are released during the enzymatic hydrolysis of biomass. This mini-review explores recent advances in the structural and functional characterization of STs in filamentous fungi and yeasts, highlighting their roles in processes such as cellulase induction, carbon catabolite repression, and sugar signaling pathways.

Background: Radiofrequency ablation guided by ultrasound (RFA-USG) is an alternative treatment for primary hyperparathyroidism (PHPT) patients. Despite showing accurate precision and minimal invasion, its efficacy remains questionable.

Methods: We searched PubMed, Embase, Scopus, Cochrane Library, Portal Regional da Biblioteca Virtual em Saúde (BVS), Web of Science databases for randomized controlled trials (RCTs) and observational studies evaluating RFA-USG in PHPT patients.

Background And Objective: Sarcopenia, characterized by the progressive loss of skeletal muscle mass (MM) and muscle function, is a common and debilitating condition in cancer patients, significantly impacting their quality of life, treatment outcomes, and overall survival. The pathophysiology of sarcopenia is multifactorial, involving metabolic, hormonal, and inflammatory changes. Recent research highlights the role of chronic inflammation in the development and progression of sarcopenia, with pro-inflammatory cytokines being key mediators of muscle catabolism.
