2.4. Animals One hundred twelve adult male Wistar rats (Pasteur Institute‚ Tehran‚ Iran) weighing 220-250 g were housed in groups of four per cage in a controlled environment (temperature 23±1°C‚ 12h light/dark cycle) with free access to food. Rats were habituated to the new environment for seven days before the test. All experiments were performed in accordance with the guide for the care and use of laboratory animals (IR.SBMU.nrc.REC.1390.20) approved by the Research and Ethics Committee of the

THE EFFECTS OF CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis

N-acetyl cysteine (NAC) is a small molecule containing a thiol group. It was first introduced as a mucolytic drug in the 1960s. NAC has been found to have an antioxidant effect‚ acting as a free-radical scavenging agent and a precursor of reduced glutathione (GSH). These effects provide the organism with crucial defense mechanism towards

Magnesium‚ an abundant mineral in the body‚ is naturally present in many foods‚ added to other food products‚ available as a dietary supplement‚ and present in some medicines (such as antacids and laxatives). Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body‚ including protein synthesis‚ muscle and nerve function‚ blood glucose control‚ and blood pressure regulation [1-3]. Magnesium is required for energy production‚ oxidative phosphorylation

Curcumin has been found to be a potent inhibitor of tumour growth and cell proliferation. This activity is linked to curcumin’s antioxidant effect and free radical scavenging effect (Akram et al‚ 2010). It inhibits cancer development and progression‚ thereby targeting multiple steps to malignancy. It has the ability to act like a blocking agent thereby inhibiting the initiation step of cancer by preventing the activation of carcinogen‚ and also as a suppressing agent thereby inhibiting malignant

Additionally consumption results in a reduction of glutathione content (Sian et al.‚ 1999). What have been good and bad consequences of the synthesis of MPTP? MPTP negatively affects the body by penetrating the blood-brain barrier and entering the brain cells. MPTP is not toxic‚ however when it oxidizes it

GROWTH PERFORMANCE OF BROILERS FED MICRO-PELLET BOOSTER DIET ON THE FIRST SEVEN DAYS OF BROODING Thea Pamela S. Ponce‚ Veneranda A. Magpantay‚ Edwin S. Luis Abstract One hundred day-old broiler chicks were raised for 35 days to determine their growth performance when fed micro-pellet booster diet on the first week of brooding. Booster mash (BM) and micro pellet booster (MPB) were fed to two separate groups at brooding stage. Birds were fed similar diet thereafter. Production parameters were compared
