A Nutritional Paradigm to Impede Cataract Initiation: A Narrative Review of Emerging Perspective on Nutraceuticals

Future Postharvest and Food, EarlyView.
By lowering oxidative stress and lens protein aggregation, nutraceuticals enriched with antioxidants may reduce the development of senile cataracts, demonstrating their potential as supplemental, non‐pharmacological cataract preventive methods. ABSTRACT This review explores the emerging evidence to accommodate the developing requirement of non ...

Understanding pre‐eclampsia and fetal growth restriction at high altitude: A narrative review

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Pre‐eclampsia (PE) and fetal growth restriction (FGR) are among the leading causes of maternal and perinatal morbidity and mortality worldwide. Both conditions are more frequent and severe at high altitudes due to physiological changes in oxygen availability and vascular adaptation.

Ancient Yersinia pestis genomes from across Western Europe reveal early diversification during the First Pandemic (541–750)

, 2019
The first historically documented pandemic caused by Yersinia pestis began as the Justinianic Plague in 541 within the Roman Empire and continued as the so-called First Pandemic until 750.

Diversity, transfer potential, and transcriptional activity of virus‐carried antibiotic resistance genes in global estuaries

iMetaOmics, EarlyView.
Estuaries are vital hotspots for antibiotic resistance genes (ARGs) due to substantial antibiotic pollution. Although viruses have been proposed as key reservoirs and important disseminators of ARGs in environments, their contribution to the estuarine antibiotic resistome remains largely unknown.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Epigenetic inflammatory memory and periodontal disease: Mechanisms and clinical significance for comorbidities

Journal of Periodontology, EarlyView.
Abstract Historically, immunological memory was considered an exclusive feature of adaptive immunity. However, innate immune cells have recently been shown to record and maintain epigenetically imprinted memory of earlier infectious or inflammatory challenges.

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.
