The aim of this study was to investigate the physiological responses during the time limit at the intensity of the peak velocity of the Carminatti's test (T-CAR). Ten professional futsal players (age, 27.4 ± 5.8 years, body mass, 78.8 ± 8.5 kg, body height, 175.8 ± 6.8 cm, body fat mass, 14.1 ± 2.6%) took part in the study. The players performed three tests, with an interval of at least 48 hour...

A brush border preparation from rat intestine was incubated with rat intrinsic factor-vitamin B12 complex in 0.01 M Tris-HCl buffer, pH 7.4. The 57Co-B12 uptake to brush borders was proportional to the amount of protein or to alkaline phosphatase activity in the preparations. The uptake increased with time of incubation. At 37degreesC, the uptake after incubation for 15 min was 80-85% of that f...

The most important pollutants in wastewater are heavy metal ions. In this paper, the effects of various parameters such as pH, contact time, initial concentration, and temperature on the adsorption of Cu (II) by nanochitosan (NCS) was investigated in batch experiment. Nanochitosan was prepared based on ionic gelation and charac­terized by means of Fourier Transform Infrared Spectroscopy (FTIR),...

Xenografts (s.c. and i.p.) of human ovarian cancer, shown to express the tumor associated antigen defined by the monoclonal antibody HMFG2, were used to investigate in vivo localization of the radioiodinated antibody after i.p. and i.v. injection. Following i.v. injection, maximum uptake (31.4 +/- 3.5%/g s.c. tumor) was seen in s.c. tumors at 48 h after injection. Tumor:normal tissue ratios inc...

abstract uranium is a natural heavy metal widely dispersed across the earth crust. in many cases due to anthropogenic disturbance, it has been found beyond its natural abundance which resulted in soil-water pollution. the objective of this study was to investigate the capability of iranian natural zeolite clinoptilolite for removal of uranium (vi) from aqueous solutions. in order to optimize re...

zinc (zn) and copper (cu) are essential elements and increased plant growth in low concentrations. while high concentrations of these elements as a limiting factor, can cause adverse symptoms on the plants. in the present study, the uptake of micronutrient and macronutrient by pennyroyal were studied in a zn and cu deficiency and toxicity in soil. three levels of copper (0, 5 and 25 mg/kg) and ...

effects of yeast extract (ye) (0, 0.05, 0.1, 0.2, 0.5 and 1%) were investigated on rosmarinic acid (ra) accumulation and tyrosine aminotransferase (tat) gene expression in melissa officinalis seedlings at different time intervals (4 and 17 hours). based on the results, only ye concentrations of 0.05%, 0.1%, and 0.2%, for the 17-hour treatment, significantly stimulated ra biosynthesis pathway. a...
