Biogenic Synthesis of Silver and Iron Nanoparticles Derived From Grewia Optiva Leaf Extract: A Novel Approach for Antidiabetic, Anticoagulant and Anti‐Inflammatory Therapies

International Journal of Chemical Kinetics, Volume 58, Issue 4, Page 159-174, April 2026.
ABSTRACT This study presents the green synthesis of silver (Ag‐NPs) and iron nanoparticles (Fe‐NPs) using aqueous leaf extract of Grewia optiva as a natural reducing and stabilizing agent. The extract was prepared using a Kjeldahl apparatus under controlled heating. Nanoparticle synthesis was optimized by varying pH, temperature, and salt concentration,

Senescence‐Driven Remodeling Defines an Aggressive and Immunomodulatory Subtype of Endometriosis

Aging Cell, Volume 25, Issue 4, April 2026.
Senescence in ectopic endometrial cells promotes SASP‐mediated M2 macrophage polarization and enhanced invasiveness of endometriotic lesions. PAK4 drives this process via PI3K/AKT signaling, while stigmasterol suppresses PAK4 and alleviates senescence‐associated immune remodeling. ABSTRACT Endometriosis is a benign yet invasive disease characterized by

Antioxidant activity of phytosterols, oryzanol, and other phytosterol conjugates

Journal of the American Oil Chemists' Society, 2002
AbstractAntioxidant activity of phytosterols, oryzanol, ferulic acid ester of sterols, corn fiber oil, and rice bran oil was investigated. Commercial soybean oil and distilled soybean oil FAME were used as substrates for both oxidative stability determination and viscosity analysis after the oil was oxidized.

A Cluster of Three snoRNAs Including Jouvence Required in the Gut Determines Lifespan and Confers Neuroprotection Through Metabolic Parameters

Aging Cell, Volume 25, Issue 4, April 2026.
The disruption of a cluster of three snoRNAs in the epithelium of the gut deregulates the lipid and sterol (including the cholesterol) homeostasis. At the whole‐organism level, this chronic deregulation, all along life, decreases lifespan and leads to neurodegenerative lesions in old flies.

The Oldest Traces of Alcoholic Beverages in the Border Zone of the North and East European Plains

Archaeometry, Volume 68, Issue 2, Page 153-172, April 2026.
ABSTRACT Analysis of organic compounds preserved on pottery from the Bell Beaker community and the initial phase of the Trzciniec Cultural Sphere in the border zone of the Eastern and North European Plains was prompted by traces of alcoholic beverages found in contextually and formally analogous discoveries of more westerly provenance.
