Bisphenol F disrupts lipophagy and lysosomal acidification via ATGL-SIRT1-PPARα signaling in NAFLD-like hepatic changes

Ecotoxicology and Environmental Safety
Bisphenol F (BPF), a widely used substitute for bisphenol A (BPA), has raised growing concerns due to its potential metabolic toxicity. Recent studies suggest that BPF exposure is associated with lipid accumulation and non-alcoholic fatty liver disease ...

Adenosine Triphosphatase Activity of Tritrichomonas foetus [PDF]

Journal of General Microbiology, 1979
Homogenates of Tritrichomonas foetus exhibited a Mg2+-dependent adenosine triphosphatase (ATPase) activity, with a pH optimum in Tris buffers of 8.2 to 8.3. The activity was not sensitive to oxygen. At high concentrations, quercetin and 4-chloro-7-nitrobenzofurazan inhibited ATPase activity in the cytoplasmic extract by 20 and 70%, respectively ...

Cell Mechanics in Cancer: Integrating Mechanotransduction Pathways Within the Tumor Microenvironment

Journal of Cellular Physiology, Volume 241, Issue 5, May 2026.
ABSTRACT Single‐cell mechanical properties such as stiffness, elasticity, and viscosity, are crucial in governing biological processes like migration, proliferation, and differentiation. In cancer, the mechanical properties of cells undergo significant alterations, which contribute to tumor growth, metastasis, and resistance to therapy.

The pharmacokinetics and safety of vonoprazan in adolescents and children with gastroesophageal reflux disease

Journal of Pediatric Gastroenterology and Nutrition, Volume 82, Issue 5, Page 1153-1161, May 2026.
Abstract Objectives Vonoprazan, a potassium‐competitive acid blocker, provides more rapid, potent, and durable elevations in gastric pH than proton pump inhibitors in adults and may be a treatment option for adolescents and children with gastroesophageal reflux disease (GERD).

Regulation of reactivated contraction in teleost retinal cone models by calcium and cyclic adenosine monophosphate. [PDF]

, 1984
We have been using lysed cell models of teleost retinal cones to examine the mechanism of contraction in nonmuscle cells. We have previously reported that dark-adapted retinas can be lysed with the detergent Brij-58 to obtain cone motile models that ...

Adenosine Triphosphatase Activities of Muscle Sarcolemma

Journal of Biological Chemistry, 1973
Abstract Isolated sarcolemma hydrolyzed ATP in the presence of Mg2+ and Ca2+. MgATPase was stimulated by low concentrations of Ca2+ and inhibited by high concentrations of this cation. Membranes hydrolyzed p-nitrophenylphosphate in the presence of Mg2+; this activity was stimulated by Ca2+ and K+.

Microplastic Impacts on Seafood: A Global Synthesis of Experimental Findings

Fish and Fisheries, Volume 27, Issue 3, Page 591-606, May 2026.
ABSTRACT Plastic pollution is a growing global concern, with plastic and microplastic particles now widespread in aquatic environments. Microplastics are frequently ingested by marine organisms, including commercially important seafood species. Ingestion can lead to a range of biological effects, influenced by the size, type and quantity of plastic, as

Regulation of collecting tubule adenosine triphosphatases by aldosterone and potassium

, 1993
To examine the precise role of potassium and aldosterone on acid-base composition and on collecting tubule ATPases, glu-cocorticoid-replete adrenalectomized rats were replaced with zero, physiological, or pharmacological doses of aldosterone and were fed

Multiple Periapical Lesions Influence the Expression of TLR4/NF‐κB Pathway Components and the Development of Hepatic Injuries in Healthy and Chronic Alcohol‐Consuming Rats

International Endodontic Journal, Volume 59, Issue 5, Page 863-872, May 2026.
ABSTRACT Aim To evaluate the impact of multiple apical periodontitis (AP) on the expression of TLR4/NF‐κB pathway components, proinflammatory cytokine levels, and development of hepatic injuries in rats with and without chronic alcohol consumption. Methodology Thirty‐two rats were assigned to four groups (n = 8): Control, AP, Alcohol, and Alcohol+AP ...

TOTAL ADENOSINE TRIPHOSPHATASE ENZYME ACTIVITY IN ANONCHOTAENIA GLOBATA (LINST 1879)

, 1994
Adenosine triphosphatases play a vital role in releasing energy at required site by uncoupling the ATP into Phosphate and ATP or ADP into PO4 and AMP. These enzymes are useful in active transport in the living cells.
