Reduced metabolic rate and oxygen radicals production in stored insect sperm.
Females of internally fertilizing species can significantly extend sperm lifespan and functionality during sperm storage. The mechanisms for such delayed cellular senescence remain unknown. Here, we apply current hypotheses of cellular senescence developed for diploid cells to sperm cells, and empirically test opposing predictions on the relationship between sperm metabolic rate and oxygen radi...
متن کاملComputational Model of Reaction Mechanism of Alkyl Peroxy Radicals with Organic Compounds in the Presence and Absence of Oxygen
On the basis of experimental data a kinetic model for the heterogeneous interaction between alkylperoxyradicals and organic compounds in Langmuir- Hinshelwood approach at room temperature has been offered.The effect of oxygen on the kinetics of process in the presence, [O2]o = 1 x 1011 – 1.6 x 1012 molecules.cm-2, and absence of oxygen has been analyzed. Over time the chain degenerate branching...

The reactive oxygen species, the highly reactive metabolites of oxygen, play a crucial role in both the normal function and the metabolism of sperm cells. Oxygen radicals achieve their physiological effects in the cells only if there is a proper balance between their production and degradation. In case of radicals’ production exceeding the antioxidant capacity of the semen, there is an oxidativ...
متن کاملDevelopment of a Method for measuring Reactive Oxygen Radicals Levels In Vitro and Study the Effects of Vitamin C and E on Radical Production Reaction
Background: Free radicals and reactive oxygen species(ROS) are the most important factors in formation of oxidative stress reaction. Now, radical damage has been suggested to contribute to a wide variety of diseases such as Alzheimer, atherosclerosis and cancer. Transition metal ions in the presence of the various biomolecules produce these active compounds. The aim of this study is introducing...
متن کاملChemosensory and hyperoxia circuits in C. elegans males influence sperm navigational capacity
The sperm's crucial function is to locate and fuse with a mature oocyte. Under laboratory conditions, Caenorhabditis elegans sperm are very efficient at navigating the hermaphrodite reproductive tract and locating oocytes. Here, we identify chemosensory and oxygen-sensing circuits that affect the sperm's navigational capacity. Multiple Serpentine Receptor B (SRB) chemosensory receptors regulate...
