1‐Methylcyclopropene Containing‐Paper Enhances the Storability of Anxi Persimmon by Regulating Energy Metabolism

Future Postharvest and Food, EarlyView.
1‐Methylcyclopropene (1‐MCP) containing‐paper delayed the color change and maintained higher rate of commercially acceptable fruit in Anxi persimmons during storage were attributed to the increased activities of H+‐ATPase, Ca2+‐ATPase, and Mg2+‐ATPase and higher levels of ATP content and energy charge (EC).

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

Therapeutic Targeting of ATP7B in Ovarian Carcinoma. [PDF]

, 2009
PURPOSE: Resistance to platinum chemotherapy remains a significant problem in ovarian carcinoma. Here, we examined the biological mechanisms and therapeutic potential of targeting a critical platinum resistance gene, ATP7B, using both in vitro and in ...

Biomarkers for the estimation of isoproterenol‐induced myocardial infarction: A review of key parameters

Journal of Intelligent Medicine, EarlyView.
Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

Membrane transporter genes predict chemoradiotherapy response in patients with cervical cancer [PDF]

Einstein (São Paulo)
Introduction: Cervical cancer is the fourth most common cancer in women worldwide. Resistance to chemoradiotherapy in cervical cancer has been widely associated with membrane transport-related genes, particularly those encoding efflux transport proteins,

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 ...

Cardenolide‐Engineered Extracellular Vesicles Augment Drug Uptake and Cytotoxicity in Non‐small Cell Lung Cancer Cells

Small Methods, EarlyView.
Cardenolide‐functionalized extracellular vesicles enable targeted delivery of the chemotherapeutic doxorubicin to A549 lung cancer cells by binding Na+/K+‐ATPase, which is overexpressed in these cells. Surface‐modified, drug‐loaded EVs exhibit enhanced cytotoxicity compared to unmodified EVs and free drug, suggesting this system may lower the effective

Analysis of the Movement of Chlamydomonas Flagella: The Function of the Radial-spoke System Is Revealed by Comparison of Wild-type and Mutant Flagella [PDF]

, 1982
The mutation uni-1 gives rise to uniflagellate Chlamydomonas cells which rotate around a fixed point in the microscope field, so that the flagellar bending pattern can be photographed easily .

Spreading depolarization and its influence on epileptiform activity

Epilepsia, EarlyView.
Abstract Spreading depolarization (SD) is a transient disruption of electrographic activity that slowly propagates through the gray matter by chemical contiguity, and it is characterized by a large depolarization of neurons and glial cells. SD, which is associated with massive changes in ion homeostasis, including extreme increases in [K+]o, was shown ...
