Introduction: Nutritional literacy is skills and the degree capacity of privates to obtain, process and understand nutrition information to make good decisions about nutrition. The use of this ...information and nutritional services leads to health promotion. This study examined the status of nutritional literacy in elementary school teachers in Yasuj and its related factors. Methods: In this Cross-Sectional study, a questionnaire of 35 items belonging to Turkey was used. After translation-retranslation and determine its validity for assessing nutritional literacy, it is used in 110 persons of elementary school teachers in Yasuj. The samples were selected by multistage stratified sampling and questionnaire was completed for them. The data were analyzed by using descriptive and analytical statistics. Findings: The average age of participants was 39.48±3.2. The results showed that the mean score of nutrition literacy for participants was 27.14± 3.2. 22.7 percent of teachers had limited or poor nutrition literacy. Teachers with less work experience and bachelor's and higher degree had more nutritional literacy scores. The least number of correct answers was related skills of food centers determination, computing skills and reading of food labels. Conclusions: Overall, according to the level of nutritional literacy in different parts of the group of teachers, it should be considered the designing of interventions to improve nutrition literacy. Because of its uniqueness in Iran, this questionnaire can be used as needs assessment tool in nutritional interventions in Iranian society.
Date Palm Pollen (DPP) and Astragalus genus are used in some countries for the treatment of infertility.
This study was designed to investigate effects of DPP and Astragalus ovinus (A.Ovinus) on ...fertility in healthy adult male rats.
Thirty-six rats were divided into six groups (n=6) including control and five treatment groups. DPP (120, 240 and 360 mg/kg) and A.ovinus (100, 500 mg/ kg) were orally given to the treatment groups. After thirty-five days, blood samples were taken to determine serum levels of FSH, LH, testosterone and estradiol. Weight of testis and epididymis, sperm count, sperm motility, seminiferous tubules diameter (STD), germinal cell layer thickness (GCLT), sertoli, leydig and spermatogonia cells were also evaluated.
DPP at the of 120 and 240 mg/kg doses significantly raised the ratio of testis or epididymis to body weight, sperm count, sperm motility , and estradiol level compared to the control group (p<0.05). LH and testosterone levels only noticeably increased at 120 mg/kg of DPP (p<0.01 and p<0.001 respectively). STD increased in the three applied doses (p=0.001). A. ovinus extract at the indicated doses produced a significant reduction in the ratio of testis or epididymis to body weight and sperm motility (p<0.05). Sperm count, spermatogonia, leydig cells and FSH level decreased at dose of 500 mg/kg. Furthermore, GCLT, spermatogonia cells, and serum estradiol level increased at 100 mg/kg dose of A. ovinus.
Our findings indicate that DPP could improve fertility factors, while A.ovinus can exhibit deleterious effects on gonad and sperm parameters in rats.
Background. Increased oxidative stress play an important role in the risk of cardiovascular disease, mortality, and mortality patients undergoing dialysis. Nasturtium officinale (watercress) contains ...numerous phytochemical compounds that act as an antioxidant by preventing oxidative damage to biomolecules. Therefore, this research aimed to explore the effect of the ethanolic extract of Nasturtium officinale (EENO) on antioxidant and biochemical markers of hemodialysis patients. Methods. In this double-blind, placebo-controlled trial, 46 hemodialysis patients were randomly recruited to consume either 500 mg/day EENO (n = 23) or placebo capsule (n = 23) for 4 weeks, at Shahid Beheshti Hospital, Yasuj, Iran, in 2019. Biomarkers of oxidative stress including glutathione peroxidase (GPX), superoxide dismutase (SOD), malondialdehyde (MDA), total oxidant status (TOS), total antioxidant capacity (TAC), and total sulfhydryl protein (T-SH) and biochemical parameters such as BUN, Hb, WBC, PLT, Ca, Ph, K, ALB, TChol, TG, LDL, and HDL were evaluated on days 0 and 28. Results. The serum levels of MDA and BUN significantly decreased after taking EENO supplementation P<0.001; however, SOD activity increased during the same period P<0.001. The serum levels of TAC remained constant in the intervention group, while it significantly declined in the placebo group P<0.09. The extract also prevented elevation in the serum levels of LDL and TG compared to the placebo group, although it was not statistically significant. Conclusions. The data indicated that the consumption of EENO improved some of the antioxidant parameters and minimizes the change in TG and LDL in hemodialysis patients. Therefore, due to the role of these factors in mortality and morbidity of dialysis patients, EENO can improve the condition of dialysis patients. However, more studies with longer intervention times and different doses of EENO are recommended.

) ionic liquid (IL) using a sol gel ...technique which was used for stir bar sorptive extraction (SBSE) of carbofuran and propoxur. The extracted analytes were then quantified by high performance liquid chromatography (HPLC) equipped with an ultra violet detector. The best extraction performance for carbofuran and propoxur was obtained through the optimization of the factors affecting SBSE including the pH of the sample solution, ionic strength, extraction time, volume of desorption solvent, desorption time, and stirring speed. The fractional factorial design (FFD) was used to find the most important factors, which were then optimized by the central composite design (CCD) and the desirability function (DF).

Background & aim: The effectiveness of the Transtheoretical model for changing nutritional behavior has been questioned by some studies. The purpose of this study was to investigate the relationship ...between self-efficacy and decisional equilibrium and transfer among the stages of behavior change of a calorie balance intake among obese women inYasuj, Iran. Methods : The data of the present descriptive analytical study were baseline data of 447 obese or overweight who were selected using the random cluster method. Based on the Transtheoretical model, individuals pass stages of change, which are precontemplation, contemplation, preparedness, action and maintenance. Two other main constructs which affect the stages of behavior change are self-efficacy and decisional balance. Demographic and anthropometric variables and stages of change, self-efficacy, decisional equilibrium pros and cons related to calorie balance intake were measured using valid and reliable questionnaires. Results: The participants average age was 33.49 years. Neither demographic nor anthropometric variables changes were significant among the stages of behavior change except literacy level before high school ( P=.047,OR=.502, %95 CI=.255 ~ .990). A significant change was observed in self-efficacy ( F(4.425)= 27.09, P= .000),decisional equilibrium (F(4.394), P= .004), and pros (F(4.430)=5.33, P=000), while no significant change was observed among cons (F(4.400)=1.83, P=.123). Conclusion: The findings confirmed the specific model of self-efficacy, decisional equilibrium and pros which predict that the obese women transfer between the five stages of calorie balance intake.

The global demographic, socio-economic and technological changes linked with lifestyle modifications are widely considered to be the underlying cause of the increased prevalence of CVD and other ...non-communicable disease worldwide. Understanding the role of the lifestyle factors in associations with these problems is important for treatment and prevention. The aims of the present thesis were: 1) To evaluate the associations between some lifestyle factors, body weight and shape, and CVD risk factors. 2) To determine the combination association between lifestyle factors and body weight and CVD risk factors. 3) To evaluate the effects of a smoking cessation program on energy balance. To achieve these aims a secondary analysis of Scottish Health Survey (SHS) 1998 and an observational study have been carried out. The relationships between smoking status and body size and shape have been examined using the SHS data from those aged 16-74 years. After adjustment for some confounding factors, BMI was lower in current smokers and higher in ex-smokers (p<0.001) when compared to non-smokers in the survey population as a whole. Smoking was associated with a lower BMI in the sample as a whole, but not for the youngest age group. Smoking cessation was associated with weight gain. Smoking and obesity were the two major risk factors, which showed the strongest associations with the CVD risk factors, and their combination exaggerated CVD risk factors. Achievement of currently recommended physical activity levels were associated with lower BMI and prevalence of obesity, and a smaller WC and WHR. However, approximately 50% of active subjects were overweight and obese. These levels of activity were associated with lower CVD risk factors, however the joint associations of physical activity and BMI showed that obese active people still had higher CVD risk factors than inactive people with BMI < 25 kg/m2. Smoking and inactivity were two major modifiable behaviours that showed the strongest associations with unhealthy dietary habits. Smoking cessation was associated with increased body weight and WC within weeks of cessation, particularly in females with NRT. Attrition rates were high and effective weight maintenance strategies may improve this.
