ABSTRACT
Background and Objectives: There is limited available data about the effects of antioxidant supplements on changes of hematological parameters after exercise. This study was carried out to investigate the effect of short-term CoenzymeQ10 supplementation on white blood cells, hemoglobin and red blood cell indices in non-athlete men after relatively intense running
Materials and Methods: Twenty healthy inactive men [25+/-3 years, fat 13+/-2. % and VO2max 41+/-2 ml/kg/min] in a randomized and double-blind design were allocated in two equal groups: supplement [2.5 mg/kg/day Coenzyme Q10] and placebo [2.5 mg/kg/day dextrose] groups. After the 14-day supplementation therapy, all subjects were participated in an aerobic exercise with 75% VO2max on the treadmill for 30 minutes. Blood samples obtained before the Q10 supplementation along with before and after the exercise protocol
Results: Ingestion 14-day coenzymQ10 supplementation on indexs [RBC, Hg, MCV, MCH, MCHC, Hct, WBC,PLT, lanphosit percentages, notrophils and other blood cells] had no significant effect [P>0.05] on basal parameters. Moreover, aerobic exercise causes lower red blood cells counts, hemoglobin and hematocrit and increase White blood cells and platelete [P<0.05], However, the rang of lower red blood cells, hemoglobin, hematocrit and increase white blood cells in supplementation group after aerobic exercise low was that placebo group [P<0.05]
Conclusion: Tngestion 14-day coenzymQ10 supplementation [with 2/5 g/kg/day] in effective on withe blood cells, hemoglobin and red blood cell indices after that aerobic exercise
ABSTRACT
The present study designed to test effects of defatted soy-fortified wheat bread on the organoleptic properties as well as influences on rat growth rate. Defatted soy flour [DSF] was blended with wheat flour with extraction rate of 82-84% at 3, 7, and 7% levels plus 3% sugar. Bread produced with these blends compared with regular Taftoon bread and was tested for chemical and organoleptic characteristics. The organoleptic characteristics of blends consist of taste and flavor, crust texture, fragrance and aroma, appearance, bendability, and overall acceptability were determined through taste panel by 213 judges. Forty Sprague Dawley rats were randomly given codes and allocated to different groups via tables with random numbers to feed on three DSF-fortified bread blends and control bread for 30 days. The blending of wheat flour with DSF altered the organoleptic properties of breads. Addition of DSF increased significantly the protein and ash content of the bread [P < 0.05]. Organoleptic test indicates that the best formulation is between 3 and 7% fortifications of DSF blends. In biological evaluation, rats fed the control diet had the lowest body weight gain and their food efficiency ratio was significantly different [P < 0.05] in compare with 7% DSF-fortified blend. It was concluded that overall acceptability score significantly decreased with increasing DSF substitution level. Rats fed 7% DSF-fortified blend showed privileged food efficiency ratio. Then, the best formulation is between 3 and 7% DSF bread. This formulation can nourish all human at risk of malnutrition
ABSTRACT
Sleep apnea is defined as more than 10 seconds to stop the air flow in the adult airway, which may occur due to upper airway obstruction during sleep. Sleep apnea is highly prevalent among patients with cardiovascular disease, so that 50% of patients with atrial fibrillation suffer from sleep apnea. Therefore, this current study discussed the risk of sleep apnea in patients with atrial fibrillation. This comparative-descriptive study with convenience sampling was performed on 150 patients with atrial fibrillation and 150 patients without atrial fibrillation admitted to CCU of Imam Khomeini's hospital, Saghez, Iran. Patients were matched for age and sex. Data was collected using demographic and Berlin questionnaire. Data analysis was performed by SPSS16 statistical software and descriptive and inferential statistical tests. Blood pressure in patients with atrial fibrillation was significantly higher than patients without atrial fibrillation [p=0.001]. In the groups with and without atrial fibrillation, 60% and 36% had a high risk of sleep apnea, respectively. Patients with sleep apnea were prone 2.98 times to atrial fibrillation more than those without this disorder. According to high incidence of sleep apnea and atrial fibrillation in the CCU, using the screening methods for patient's identification to reduce the risk factors among these patients seems to be necessary
