Background: Critical macromolecules of cells such as DNA are in exposure to damage of free radicals that induced from the interaction of ionizing radiation with biological systems. Selenium and vitamin-E are natural compounds that have been shown to be a direct free radical scavenger. The aim of this study was to investigate the radioprotective effect of selenium and vitamin-E separately and sy...

Süt, yaşamın her evresinde önemli bir besin kaynağıdır. Sütün bileşimi, kalıtımsal, fizyolojik ve çevresel faktörler ile yetiştirme koşullarına bağlı olarak büyük ölçüde değişir. Kaliteli süt üretimi, ekonomik anlamda sağlık açısından çok önemlidir. Günümüzde endüstrideki hızlı gelişmeye ortaya çıkan çevre kirliliğinin olumsuz etkilerinden birisi de insan hayvanların ağır metallere maruz kalmas...

Complement, Electron Spin Resonance, Free Radicals We describe the appearance of a free-radical signal in the ESR spectrum of normal human serum incubated with several complement activating agents. The intensity of this signal is dependent of dose of activating agents, time and temperature. Signals elicited by different complement activators differ in morphology and kinetics. Inhibition by trea...

background toxoplasma gondii is an opportunistic parasitic organism causing infection in many mammals, including immunosuppressed patients. toxoplasmosis as an opportunistic infection is highly prevalent among patients receiving a kidney transplant. objectives the purpose of this study was to identify and determine the prevalence of toxoplasma gondii in clinical samples collected from patients ...

OBJECTIVE The present study was designed to analyze the serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transferase, and the hematocrit in patients with chronic kidney disease who were undergoing peritoneal dialysis or hemodialysis. PATIENTS AND METHODS Twenty patients on peritoneal dialysis and 40 on hemodialysis were assessed, and the patients were matched according ...

Glucose obtained from unprocessed blood samples can decrease by 5%-7% per hour due to glycolysis. This study compared the impact of glucose degradation on measured glucose values by examining two different collection methods. For the first method, blood samples were collected in tubes containing sodium fluoride (NaF), a glycolysis inhibitor. For the second method, blood samples were collected i...

Materials and methods: A small, medium, and large piglet (N = 1095) were selected per litter 1 to 2 days before weaning from 20 Ontario (Canada) swine farms. Serum and whole blood samples and body weights were collected. Three weeks later, a second body weight and blood sample were collected from the same pigs. Hemoglobin (Hb) and other blood parameters were analyzed to assess iron status and a...
