Gas Chromatography‐Mass Spectrometry‐Based Phytochemical Profiling and Bioactivity‐Guided Fractionation of Psidium guineense Stem Extracts: In Vitro and In Silico Insights Into Antioxidant, Antidiabetic and Antibacterial Potentials

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Psidium guineense (Myrtaceae) is traditionally used for various medicinal purposes, although its stem remains underexplored. This study provides the first integrated phytochemical, pharmacological and computational evaluation of the stem extracts to elucidate their antioxidant, antidiabetic and antibacterial potential.

Nanoshell Fabrication Techniques for Probiotic Encapsulation: A Comprehensive Review

eFood, Volume 7, Issue 3, June 2026.
ABSTRACT Probiotics, beneficial microorganisms, confer numerous health benefits when administered. However, their efficacy is hindered by harsh gut conditions, including acidity, bile acids, and enzymatic degradation. To overcome these challenges, encapsulation and nanoshell technology have emerged as a pivotal strategy to enhance probiotic stability ...

Dopamine‐Induced Seizure in a Heart Failure Patient: A Case Report and Review of Neurotoxic Implications

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT In heart failure patients, dopamine therapy, particularly at higher doses, may induce seizures due to its impact on cerebral blood flow and exacerbation of underlying hypoxemia and electrolyte imbalances. Close monitoring and cautious use of dopamine, with consideration of alternative inotropic agents like dobutamine, are essential to mitigate
