the aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in dunaliella salina teod. the algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 m nacl under three illumination regimens [4500 (control), 9000 and 11000 lux]. the results showed that most electrophoresis protein bands were separa...

This study evaluated the effect of the intermittent light program on serum and brain melatonin concentrations, antioxidant enzyme activities, and homocysteine concentration in broiler chickens. A total of 60 one-day-old broiler chickens (Cobb 500) were distributed in three light-proof controlled rooms (20 chicks per room). All birds were reared in continuous light until 3 days of age. Then, chi...
