Positive Chemotactic Flasklike Colloidal Motors Propelled by Rotary FoF1-ATP Synthases

Research
Living microorganisms can perform directed migration for foraging in response to a chemoattractant gradient. We report a biomimetic strategy that rotary FoF1-ATPase (adenosine triphosphatase)-propelled flasklike colloidal motors exhibit positive ...

Ultrastructural localization of adenosine triphosphatase activity in lymphocytes activated in vitro by phytohaemagglutinin [PDF]

, 1982
The ultrastructural localization of Ca 2+, Mg2+ -activated ATPase was studied in phytohaemagglutinin activated lymphocytes and in normal unstimulated lymphocytes. Cells, fixed in paraformaldehyde-glutaraldehyde, were incubated in a medium containing 3 mM

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 ...

The extracellular signal-regulated kinase (ERK) pathway: a potential therapeutic target in hypertension [PDF]

, 2012
Hypertension is a risk factor for myocardial infarction, stroke, renal failure, heart failure, and peripheral vascular disease. One feature of hypertension is a hyperresponsiveness to contractile agents, and inhibition of vasoconstriction forms the basis

Pathological Roles of Astrocytes in Traumatic Brain Injury

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
TBI induces intrinsic astrocytic changes, including reactive astrogliosis, A1 and A2 polarization, ion channels activation, pathological edema, oxidative stress, and metabolic dysregulation. These injury‐responsive astrocytes regulate neuroinflammation and tissue remodeling through dynamic crosstalk with microglia, macrophages, vascular endothelial ...

Modulation of the asymmetry of sea urchin sperm flagellar bending by calmodulin [PDF]

, 1985
Sea urchin spermatozoa demembranated with Triton X-100 in the presence of EGTA, termed potentially asymmetric, generate asymmetric bending waves in reactivation solutions containing EGTA. After they are converted to the potentially symmetric condition by

A Narrative Review of Antioxidant, Anti‐Inflammatory, Anti‐Apoptotic, Immunomodulatory, and Anticancer Properties of Rosa damascena Mill.

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Rosa damascena Mill. exhibits a broad spectrum of pharmacological activities mediated by its rich phytochemical profile. The plant enhances antioxidant defenses by increasing endogenous enzymes (CAT, SOD, GSH, GST, GPx, FRAP) and reducing oxidative stress markers (MDA, MPO).

Assignment of the Human and Mouse Prion Protein Genes to Homologous Chromosomes [PDF]

, 1986
Purified preparations of scrapie prions contain one major macromolecule, designated prion protein (PrP). Genes encoding PrP are found in normal animals and humans but not within the infectious particles.

Crystal Structure of Prp5p Reveals Interdomain Interactions that Impact Spliceosome Assembly

Cell Reports, 2013
The DEAD-box adenosine triphosphatase (ATPase) Prp5p facilitates U2 small nuclear ribonucleoprotein particle (snRNP) binding to the intron branch site region during spliceosome assembly. We present crystal structures of S.
