Bicarbonate, sulfate and thiocyanate affected distinctly the ADP/O ratio and the rate of oxygen consumption in liver mitochondria. Alterations in the ADP/O coefficient and the ATPase activity were studied in liver and heart mitochondria of control and fasted rats as well as of animals maintained under hypoxy-hypercapnic conditions. Satisfactory correlation was shown between a decrease both in the ADP/O ratio and in sensitivity of ATPase to bicarbonate in liver mitochondria of the animals subjected to these treatments.

Physical exercise is known to slow synaptic neurodegeneration and cognitive aging in Alzheimer's disease (AD). The benefits of physical exercise are related to reduced amyloid beta (Aβ) deposition and increased synaptic plasticity. Yet little is known about the mechanisms that mediate these effects.

Homologous recombination is a largely error-free DNA repair mechanism conserved across all domains of life and is essential for the maintenance of genome integrity. Not only are the mutations in homologous recombination repair genes probable cancer drivers, some also cause genetic disorders. In particular, mutations in the Bloom (BLM) helicase cause Bloom Syndrome, a rare autosomal recessive disorder characterized by increased sister chromatid exchanges and predisposition to a variety of cancers.

The WRN protein is vital for managing perturbed replication forks. Replication Protein A strongly enhances WRN helicase activity in specific in vitro assays. However, the in vivo significance of RPA binding to WRN has largely remained unexplored.

Traditional dry-curing methods have a long cycle time and low efficiency, resulting in the inconsistent quality of dry-cured ham. By applying electrical stimulation (ES) technology in the dry-curing process, it was found that ES affected mitochondrial apoptosis by modulating the intracellular environment of muscle cells, which, in turn, enhanced the quality of dry-cured pork loin. Specifically, ES accelerated glycogen and ATP depletion, which led to a rapid decline in pH.

Background: Ras-GTPase-activating protein (GAP)-binding protein 1 (G3BP1) emerges as a pivotal oncogenic gene across various malignancies, notably including nasopharyngeal carcinoma (NPC). The use of automated image analysis tools for immunohistochemical (IHC) staining of particular proteins is highly beneficial, as it could reduce the burden on pathologists. Interestingly, there have been no prior studies that have examined G3BP1 IHC staining using digital pathology.
