ABSTRACT Mitochondria provide cellular energy through oxidative phosphorylation, and thus temperature-induced constraints on mitochondrial function may be crucial to animal aerobic scope thermal tolerance. Here, we report the effect of temperature in range 5–30°C respiration rates isolated cardiac mitochondria from rainbow trout (Oncorhynchus mykiss) studied by high-resolution respirometry spec...

Background: Frozen-thawed rooster semen is not reliable for use in artificial insemination in commercial stocks. Low density lipoprotein (LDL) has been assessed for effectiveness as a cryoprotectant in the extender to improve the quality of frozen-thawed rooster semen. Although LDL has been evaluated in a few studies in other species for semen cryopreservation, to date, no study has been conduc...

Mitochondrial enzymes involved in energy transformation are organized into multiprotein complexes that channel the reaction intermediates for efficient ATP production. Three of mammalian urea cycle enzymes: N-acetylglutamate synthase (NAGS), carbamylphosphate synthetase 1 (CPS1), and ornithine transcarbamylase (OTC) reside mitochondria. Urea is required to convert ammonia protect brain from tox...

The study was conducted to determine the influence of D-aspartic acid (D-Asp) as antioxidant supplement and thawing rates on ram sperm motility, membrane integrity, abnormality, viability, mitochondria activity, malondialdehyde and antioxidant activities, and total antioxidant capacity after freezing-thawing process. Semen samples from five mature rams (3-4 years old) were diluted with extender...

conclusions in conclusion, at measurement can be beneficial for the safety or recovery of malathion-induced toxic injury in liver tissue and liver mitochondria. results in liver tissue, the activity of lpo and cat was higher in the malathion group in comparison to controls. at reduced malathion-induced lpo, sod, cat, and gpx in rat liver. coadministration of at with malathion improved lpo, sod,...

The state of lipid peroxidation (LPO), respiration and oxidative phosphorylation, mitochondrial permeability transition pore (mPTP) antiradical activity rat liver mitochondria in streptozotocin (STZ)-induced diabetes condition were studied, considered the ways correction detected membrane damages with use gossitan, isolated from cotton plant Gossypium hirsutum L. It was shown that rate states V...

In this experiment, wheat plants were exposed to drought stress during seed development then we worked on the obtained seeds. The seed mitochondrial ultra-structure, and antioxidant enzymes in seedling were investigated after exposure to seed accelerated ageing. Drought stress during seed development induced some changes in mitochondrial ultra-structure. Encountering seed development to drought...

The energy demand of cardiomyocytes changes continuously in response to variations cardiac workload. Cardiac excitation-contraction coupling is fueled primarily by adenosine triphosphate (ATP) production oxidative phosphorylation mitochondria. rate mitochondrial metabolism matched the ATP consumption cytosol parallel activation calcium (Ca 2+ ) and diphosphate (ADP). During workload transitions...
