Molecular Mimicry between Helicobacter pylori Antigens and H+,K+–Adenosine Triphosphatase in Human Gastric Autoimmunity

open access: yesJournal of Experimental Medicine, 2003
Autoimmune gastritis and Helicobacter pylori–associated gastric atrophy develop through similar mechanisms involving the proton pump H+,K+–adenosine triphosphatase as autoantigen. Here, we report that H. pylori–infected patients with gastric autoimmunity

Inhibition of adenosine triphosphatases by gold [PDF]

open access: yesArthritis & Rheumatism, 1980
AbstractInhibition of adenosine triphosphatase (ATPase) by chlorauric acid (Au3+) and gold sodium thiomalate (Au+) was studied in dog brain and kidney and in human kidney enzyme preparations. Au3+ indiscriminately affected ouabain‐sensitive (Na+ + K+‐dependent) ATPase and ouabain‐insensitive (Mg2+‐dependent) ATPase with concentrations for 50 ...

Effect in vitro of the Phenobarbital on the Activity of the Enzyme Adenosine Triphosphatase (ATPase) of Sodium and Potassium Dependent in Human Placenta.

open access: yesMedisur, 2007
Background: Most of the drugs can pass to the fetus through the placenta, conditioning alterations of the development and fetal growth. Objective: To evaluate the effect in vitro of Phenobarbital on the activity of adenosine triphosphatase of sodium and ...

Neutrophil Mobilization Triggers Microglial Functional Change to Exacerbate Cerebral Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
These study underscores the pivotal role of neutrophil‐derived myeloid‐related protein 14 (MRP14) in the pathophysiology of acute ischemic stroke (AIS). MRP14 not only disrupts mitochondrial function, thereby inhibiting microglial phagocytosis of neutrophils, but also activates microglial pyroptosis, exacerbating neuroinflammation following AIS ...

Ethanol Induced Disordering of Pancreatic Acinar Cell Endoplasmic Reticulum: An ER Stress/Defective Unfolded Protein Response Model. [PDF]

open access: yes, 2018
Background & aimsHeavy alcohol drinking is associated with pancreatitis, whereas moderate intake lowers the risk. Mice fed ethanol long term show no pancreas damage unless adaptive/protective responses mediating proteostasis are disrupted. Pancreatic

FLAGELLAR MOVEMENT AND ADENOSINE TRIPHOSPHATASE ACTIVITY IN SEA URCHIN SPERM EXTRACTED WITH TRITON X-100

open access: yesJournal of Cell Biology, 1972
Extraction with 0 04% (w/v) Triton X-100 removes the flagellar membrane from sea urchin sperm while leaving the motile apparatus apparently intact When reactivated in a suitable medium containing exogenous adenosine triphosphate (ATP), nearly 100% of the

Lysosome‐Featured Cell Aggregate‐Released Extracellular Vesicles Regulate Iron Homeostasis and Alleviate Post‐Irradiation Endothelial Ferroptosis for Mandibular Regeneration

open access: yesAdvanced Science, EarlyView.
Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

Effect of Ginkgo Biloba Extract 50 on Immunity and Antioxidant Enzyme Activities in Ischemia Reperfusion Rats

open access: yesMolecules, 2011
The aim of the study was to investigate the effect of Ginkgo biloba extract 50 (GBE50), a well-known natural antioxidant, against immunity and antioxidant enzyme activities in ischemia reperfusion (IR) rats. Rats were then divided into six groups fed for
