this experiment was conducted to determine the effect of vitamin c (vc) and coenzyme q10 (coq10) onimmunity response of broilers in cold stress condition using 500 male chicks in a completely randomizeddesign with 5 treatments and five replicates. treatments were: positive control (pc, normal conditionsgrowth without antioxidants), negative control (nc, cold stress without antioxidants), cold s...

this experiment was performed to determine the role of vitamin e and coenzyme q10 antioxidants on performance and ascites parameters of broiler chicks in cold stress conditions using a completely randomized design with 5 treatments and 5 replicates in each treatment. treatments were: positive control (pc, normal thermal conditions without antioxidants), negative control (nc, cold stress without...

Due to their unique physical, chemical, and optical properties, gold nanoparticles (AuNPs) have recently attracted much interest in the field of nanomedicine, especially in the areas of cancer diagnosis and photothermal therapy. Because of the enormous potential of these nanoparticles, various physical, chemical, and biological methods have been adopted for their synthesis. Synthetic antioxidan...

Santalum album L. (Indian sandalwood) is an economically important plant species because of its ability to produce highly valued perfume oils. Little is known about the mechanisms by which S. album adapts to low temperatures. In this study, we obtained 100,445,724 raw reads by paired-end sequencing from S. album leaves. Physiological and transcriptomic changes in sandalwood seedlings exposed to...

Thyroid hormone-induced increase in metabolic rates is often associated with increased oxidative stress. The aim of the present study was to investigate the contribution of iodothyronines to liver oxidative stress in the functional hyperthyroidism elicited by cold, using as models cold-exposed and 3,5,3'-triiodothyronine (T3)- or thyroxine (T4)-treated rats. The hyperthyroid state was always as...

The relationship between Mg-protoporphyrin IX (Mg-Proto IX) signals and plant's tolerance to cold stress is investigated. Arabidopsis seedlings grown for 3 weeks were pretreated with 2 mM glutamate (Glu) and 2 mM MgCl2 for 48 h at room temperature to induce Mg-Proto IX accumulation. Then cold stress was performed at 4°C for additional 72 h. Glu + MgCl2 pre-treatments alleviated the subsequent c...

Antioxidants protect against free-radical damage, and free radicals, in turn, are thought to underlie aging. Thus, measuring antioxidants may aid field ecologists in understanding the physiological mechanisms that underlie life-history trade-offs. Antioxidant levels are known to vary markedly in response to the stress of capture in many birds. These changes in antioxidants could result from reg...

The present investigation was carried out for appraisal of antioxidative strategies in the erythrocytes of Marwari sheep during moderate, hot and cold ambiences. Haemolysates were prepared to determine antioxidants. Antioxidants included vitamin A and vitamin C. Results revealed mean values of vitamin A and vitamin C in erythrocytes were significantly (p≤0.05) lower during hot and cold ambience...
