Despite usual iron chelating therapy based on desferrioxamine, patients affected by beta-thalassemia major (beta-TM) often develop progressive heart failure caused by myocardial iron overload, which is the leading cause of mortality within the third decade of life. Heart transplantation is a limited therapeutic option, as very often these patients have multi-organ iron deposits and infective complications (particularly hepatitis C), secondary to frequent blood transfusions. We report the case of a 26-year-old male affected by beta-TM with end-stage heart failure, who showed a dramatic improvement in symptoms and myocardial function when a new oral iron chelating agent, deferiprone, was added to standard therapy with desferrioxamine.

Introduction: Iron-mediated cell death (ferroptosis) is a proposed mechanism of Alzheimer's disease (AD) pathology. While iron is essential for basic biological functions, its reactivity generates oxidants which contribute to cell damage and death.
Methods: To further resolve mechanisms of iron-mediated toxicity in AD, we analyzed post mortem human brain and ApoEFAD mice.

This study investigated plant growth-promoting (PGP) mechanisms in Priestia aryabhattai VMYP6 and Paenibacillus sp. VMY10, isolated from tomato roots. Their genomes were initially assessed in silico through various approaches, and these observations were then compared with results obtained in vitro and in vivo.

Unlabelled: Dental caries remains a prevalent chronic disease driven by dysbiosis in the oral biofilm, with playing a central role in its pathogenesis.
Objective: This study aimed to assess the effect of D-tagatose on cariogenic risk by analyzing randomized clinical trials (RCTs).
Methods: A systematic literature review was conducted targeting RCTs published up to 2024 in eight databases and two gray literature sources.

The isolation and characterization of bioactive metabolites from species continue to represent a vital area of research, given their potential in natural product drug discovery. In this study, we characterize a new siderophore called legonoxamine I, together with a known compound, streptimidone, from the talented soil bacterium sp. MA37, using chromatographic techniques and spectroscopic analysis.

Accelerated photooxidation of salicylic acid (SA) was performed using UV radiation and hydrogen peroxide. HPLC-MS analysis showed that the primary intermediates are 2,5-dihydroxybenzoic acid, 2,3-dihydroxybenzoic acid, pyrocatechol, and phenol. Deeper oxidation leads to low molecular weight aliphatic acids, such as maleic, fumaric, and glyoxylic.
