introduction: the aim of this experimental laboratory study was to evaluate the effect of different mixing and placement techniques on compressive strength (cs) of calcium-enriched mixture (cem) cement. methods and materials: cem powder was mixed with its liquid either by hand mixing or amalgamator mixing. the mixture was loaded to cylindrical acrylic molds with 6.0±0.1 mm height and 4.0±1 mm d...

Introduction: The aim of the study was to investigate the structural and hemodynamic changes as well as cardiac transcriptional profile of the key regulatory proteins, sirtuins family (SIRT1-7), in adaptive and mal-adaptive phases of left ventricular hypertrophy (LVH). Methods: LVH was induced in male Wistar rats (190±20g) by abdominal aortic banding. The third and sixteenth weeks post-surgery ...

Background: A high-fat diet (HFD) and fat accumulation promote the oxidative stress formation, which in turn has hazardous effects on reproductive system and fertility. Therefore, the present study examines the potential positive effects of a restricted high-fat diet (RHFD) and antioxidants consumption on sperm parameters in rats. Methods: 48 male albino wistar rats divided to four groups (n=12...

objective(s) the aim of this study was to investigate the effects of aerobics, pilates exercises and low calorie diet on leptin levels and some lipid profiles and anthropometric factors in sedentary women. materials and methods forty six women (age 36.41±3.47) were recruited and divided into four groups: aerobic exercise group (ex), pilates exercise group (pilates), low calorie diet (lcd) and c...

isotherms of the binding of the anthracyciine antibiotic, adriamycin (adriblastin), to dna histone complexes was studied by means of spectroscopic analysis. the results indicated that: (a) binding of adriamycin to histones reduced the interaction of histones with dna, (b) binding of the drug to dna did not change the binding affinity of histone to dna and, (c) in the explored binding range of r

The effects of selenium (Se) on the growth and antioxidant activity in Spirulina platensis were investigated. S. platensis was grown in zarrouk medium containing three different concentrations of selenate (Na2SeO4) (0 as a control, 5 and 10 mg l-1) for 7 days. Selenate at the concentration of 5 mg l-1was found to improve S. platensis growth. However, selenate was toxic to S. platensis at the co...
