Bifenthrin Under Scrutiny: Revisiting Toxicological Evidence Amid Regulatory Gaps

Journal of Applied Toxicology, EarlyView.
ABSTRACT Despite growing health concerns, bifenthrin (BF) remains widely used for controlling agricultural and residential pests. However, different perspectives on its toxicological profile and regulatory framework warrant a revisit and update on BF regulation towards a robust risk‐safety assessment.

P4‐ATPases as Phospholipid Flippases: From Membrane Dynamics to Human Disorders

Medicine Bulletin, EarlyView.
ABSTRACT P4‐ATPases (P4 subfamily of P‐type ATPases) flippase complex includes an α‐subunit responsible for catalysis and a supporting β‐subunit, which consumes energy by catalyzing the hydrolysis of ATP, thereby facilitating the translocation of aminophospholipids from the outer to the inner leaflet of cellular membranes to maintain the asymmetric ...

Propulsion in a viscoelastic fluid

, 2007
Flagella beating in complex fluids are significantly influenced by viscoelastic stresses. Relevant examples include the ciliary transport of respiratory airway mucus and the motion of spermatozoa in the mucus-filled female reproductive tract. We consider

Dad's Diet Shapes the Future: How Paternal Nutrition Impacts Placental Development and Childhood Metabolic Health

Molecular Nutrition &Food Research, EarlyView.
This review highlights the emerging connection between paternal nutrition‐induced sperm epigenetic changes and placental phenotypes that may influence offspring metabolic health. An accompanying interactive ShinyApp allows exploration of these sperm–placenta gene networks, a framework for future research seeking to explore candidate biomarkers or ...

Sulfated Polysaccharides From Gracilaria gracilis (Red Seaweed) Restores Testicular Glucose Metabolism by Improving FSH and Insulin Signaling in Rats With Type 2 Diabetes

Molecular Nutrition &Food Research, EarlyView.
Sulfated polysaccharides from red seaweed improved testicular FSH and insulin signaling, which upregulated GLUT4 level and improved glycolysis and energy metabolism in testes of diabetic rats. ABSTRACT Testicular glucose homeostasis plays important roles in testicular energy metabolism and male fertility, but it is altered in type 2 diabetes (T2D ...

Nano Zinc Oxide Toxicity Varies With Age and Sex in Panagrellus redivivus

Environmental Toxicology, EarlyView.
ABSTRACT ZnO NPs can adsorb onto soil particles and potentially enter groundwater. Nematodes and other soil microfauna are vital to the soil's health and nutrient cycles, yet they are seriously endangered by ZnO NPs. A dose–response study using Panagrellus redivivus was applied.
