High density serum lipoprotein underwent serologic and physicochemical alterations on aging during storage at 0 degrees C. for 1 month, as judged by decrease of diffusion coefficient and increase of C' fixation. Ultracentrifugation, dialysis, and high concentrations of sodium chloride did not cause these changes. A protein sedimenting at density 1.24 in the ultracentrifuge reacted with antiseru...

Although hyperinsulinemia and decreased high density lipoprotein cholesterol concentration can occur in patients with hypertension, there is no information available concerning the dynamic state of high density lipoprotein metabolism. To address this issue, we quantified high density lipoprotein turnover in 12 patients with mild hypertension and 11 matched subjects with normal blood pressure. P...

The aim of this study was investigating some blood parameters of blue-neck male ostriches (Struthio camelus) with 4 months old after feeding a diet containing 3% sunflower oil for two months. In the morning, after about 12 h of fasting, some blood samples were collected from the wing vein of ostriches at the beginning and 60 days of study in department of animal sceince Arak university . The pl...

In the present study, we found that oxidized low density lipoprotein, but not low density lipoprotein, down-regulated base excision repair activity in extracts of mouse monocyte cell line PU5-1.8. An enzyme required in this pathway, DNA polymerase beta, was also down-regulated. In contrast, treatment of monocytes with a combination of ascorbate and alpha-tocopherol up-regulated base excision re...

Background: Risk factors of non-communicable disease (NCD) origin from early life, and exposure to environmental pollutant may be a predisposing factor. This study aimed to investigate the association of air quality index (AQI) and fine particulate matter (PM2.5) with some NCD risk factors in a sample of Iranian children and adolescents. Materials and Methods: This cross-sectional study was con...

This study was conducted to compare the bio-efficacy of herbal methionine (H-Met) relative to DL-methionine (DL-Met) on 160 “Ross 308” broiler chickens. DL-Met and H-Met were added to the basal diet in eight experimental treatments with three and four concentrations respectively in starter, grower and finisher period. Blood parameters which were measured at 24 and 42 days of age consisted of: s...
