ADENOSINE TRIPHOSPHATASE: A NEUROHISTOCHEMICAL STUDY [PDF]

Journal of Histochemistry & Cytochemistry, 1962
The location of adenosine triphosphatase in the brain has been studied in rapidly frozen-dried cerebral tissues of the Wistar rat. It is found that adenosine triphosphatase is an almost exclusively nuclear enzyme. Two tissue fractions of the cerebrum were separated, so that one sample was made up of vascular elements, and the other of neural ...

Update of the Scientific Opinion on the risks for human health related to the presence of perchlorate in food

EFSA Journal, Volume 23, Issue 5, May 2025.
Abstract The European Commission asked EFSA to update its 2014 risk assessment on perchlorate in food. Perchlorate is a contaminant of both natural and anthropogenic sources present in food and drinking water. It is a substrate for the sodium iodide symporter (NIS) and competitively inhibits the uptake of iodide into the thyroid.

Equation-of-motion MLCCSD and CCSD-in-HF oscillator strengths and their application to core excitations [PDF]

arXiv, 2020
We present an implementation of equation-of-motion oscillator strengths for the multilevel CCSD (MLCCSD) model where CCS is used as the lower level method (CCS/CCSD). In this model, the double excitations of the cluster operator are restricted to an active orbital space, whereas the single excitations are unrestricted.

Longitudinal Follow‐Up of Patients With Duchenne Muscular Dystrophy Using Quantitative 23Na and 1H MRI

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 2, April 2025.
ABSTRACT Background Quantitative muscle MRI commonly evaluates disease activity and muscle wasting in Duchenne muscular dystrophy (DMD). Disturbances in ion homeostasis contribute to DMD pathophysiology, but their relationships with disease progression is unclear. 23Na MRI may provide insights into the disease course and treatment response.

Influence of Histamine on Adenosine Triphosphatase

Experimental Biology and Medicine, 1948
In all snake venoms hitherto investigated a powerful ATP-ase (ophio-ATP-ase) has been found, which is activated by magnesium, calcium and cobalt ions and inhibited by zinc ions.1,2 Histamine and pyridoxamine act as inhibitors, epinephrine as activator.The question arose as to whether similar reactions take place in the animal tissues and thus ...

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 ...

Physiological and molecular insights into drought tolerance. [PDF]

, 2016
Water is a major limiting factor in world agriculture. In general, most crop plants are highly sensitive to even a mild dehydration stress. There are however, a few genera of plants unique to Southern Africa, called "resurrection plants" which can ...

Targeting Frequent Efferocytosis in Tumor Microenvironment is a New Direction for Cancer Treatment

Small Science, Volume 5, Issue 4, April 2025.
Phagocytosis of “apoptotic tumor cells”, known as efferocytosis, accelerates the formation of an immunosuppressive microenvironment, leading to the detriment of tumor therapy. Blocking this process represents one of the novel approaches for treating tumors.

ATP11C mutation is responsible for the defect in phosphatidylserine uptake in UPS-1 cells

Journal of Lipid Research, 2015
Type IV P-type ATPases (P4-ATPases) translocate phospholipids from the exoplasmic to the cytoplasmic leaflets of cellular membranes. We and others previously showed that ATP11C, a member of the P4-ATPases, translocates phosphatidylserine (PS) at the ...
