PURPOSE To further test the hypothesis that light-adaptation-mediated photoreceptor protection works through inhibition of apoptosis by activation and/or upregulation of neuroprotective molecules. METHODS Albino rats were born and raised in 5-lux cyclic light (12 hours OFF and ON). At 8 weeks of age, animals were adapted to 400-lux cyclic light for different periods. Light damage was induced ...

The kinetic of photo oxidative decolorization of C.I. Acid yellow 23 (AY23) was investigated in UV/ process. The semi-logarithmic of the concentrations of AY23 versus irradiation time were linear, suggesting pseudo-first order reaction. A simple kinetic model is proposed which confirms pseudo- first order reaction. The results indicate that the apparent reaction rate constant is a function of l...

Although, the circadian clock is a universal biological system in plants and it orchestrates important role of plant production such as photosynthesis, floral induction and growth, there are few such studies on cultivated species. Lettuce is one major cultivated species for both open culture and plant factories and there is little information concerning its circadian clock system. In addition, ...

n-phthaloyl gaba was administrated daily (50 mg/kg body weight-i.p) to wistar rats for 21 days and circadian rhythms of thiobarbituric acid reactive substances (tbars) and antioxidants such as reduced glutathione (gsh), catalase (cat) and superoxide dismutase (sod) were studied under constant light (ll) conditions. delayed acrophase of tbars and advanced acrophase of antioxidants (gsh, cat and ...

Recombinant DNA clones have been generated from mouse myeloma MOPC 21 immunoglobulin kappa light chain mRNA. Complementary DNA (cDNA) synthesized on kappa light chain mRNA by reverse transcriptase was made double stranded and inserted into the bacterial plasmid vector, pMB9. Approximately 70 tetracycline-resistant transformed colonies containing kappa light chain mRNA sequences were identified ...
