In this paper, a device based on wearable sensors is introduced to describe quantitative body movements in different sports. This device can be an alternative to Image processing techniques. Image processing devices have always been used to describe quantitative body movements, which in addition to being costly, have to be used in specific conditions. The device is built from a number of wireless modules that are easy to use in real-world environments with no limitations. In this method, a quantitative description of movement is made by wireless modules and is performed by the data collected from these modules. In order to analyze the data that was extracted from an athlete's body movements with these wearable sensors, the outputs are simulated in Matlab, and some of its kinematic and kinetic parameters have been studied. Then, at the end of this paper, the quality of movement of a professional athlete and a beginner athlete are compared, and the result is shown. Kinematic and dynamic analyzes on the above activities showed the following The movements are generally correctly recorded. The kinematic analyzes performed for the various movements are consistent with the facts. For example, the kinematic analysis of the recorded motions showed that the coaching movement was more beautifully performed, and this was evident qualitatively during the movement.

Acne is one of the most common diseases among young individuals. Controversial findings are reported about the effect of glycemic index (GI) and glycemic load (GL) of the diet on acne vulgaris. The aim of this study was to investigate the effect of GI and GL of diet on severity of acne.
All relevant studies on effects of GI or GL on acne published up to December 2016 were collected using PubMed, Google Scholar, Science direct, Ovid and Cochrane library.
Of 714 articles in our initial research, 6 interventional and 3 case-control studies were included.
Case-control studies revealed that patients with acne vulgaris consumed diets with a higher GI rather than control group. Intervention with a low GI diet reduced lesion counts and improved the severity of acne as well as insulin sensitivity compared with those under high GI diet.
Overall, a diet with low GI and GL could improve acne severity and inflammatory lesions.

This study was designed to assess the effects of calcium and vitamin D supplementation on the metabolic status of pregnant women with gestational diabetes mellitus (GDM). This randomized placebo-controlled trial was performed at maternity clinics affiliated to Kashan University of Medical Sciences, Kashan, Iran. Participants were 56 women with GDM at 24–28 weeks gestation (18 to 40 years of age). Subjects were randomly assigned to receive calcium plus vitamin D supplements or placebo. All study participants were blinded to group assignment. Individuals in the calcium–vita- min D group (n = 28) received 1,000 mg calcium per day and a 50,000 U vitamin D3 pearl twice during the study (at study baseline and on day 21 of the intervention), and those in the placebo group (n = 28) received two placebos at the mentioned times. Fasting blood samples were taken at study baseline and after 6 weeks of intervention. The study was completed by 51 participants (calcium–vitamin D n = 25, placebo n =26). However, as the analysis was based on an intention-to-treat approach, all 56 women with GDM (28 in each group) were included in the final analysis. After the administration of calcium plus vitamin D supplements, we observed a significant reduction in fasting plasma glucose (p < 0.001), serum insulin levels (p = 0.02) and HOMA-IR (p = 0.001) and a significant increase in QUICKI (p = 0.003) compared with placebo. In addition, a significant reduction in serum LDL-cholesterol (P=0.02) and total cholesterol: HDL-cholesterol ratio (p = 0.003) and a significant elevation in HDL-cholesterol levels (p = 0.01) was seen after intervention in the calcium–vitamin D group compared with placebo. In addition, calcium plus vitamin D supplementation resulted in a significant increase in GSH (p =0.03) and prevented a rise in MDA levels (p = 0.03) compared with placebo. Calcium plus vitamin D supplementation in women with GDM had beneficial effects on their metabolic profile.

Modification of life style, nutrional regiment and insulin therapy is used for improvement of pregnancy outcomes in pregnant women with gestational diabetes mellitus (GDM). This study was done to evaluate the effect of the dietary approaches to stop hypertension (DASH) eating plan on pregnancy outcomes in pregnant women with gestational diabetes mellitus. In this clinical trial study, 52 women with GDM were randomly divided into DASH and control groups for 4 weeks. The control diet contained 45-55% carbohydrates, 15-20% protein and 25-30% total fat. The DASH was rich in fruits, vegetables, whole grains and low-fat dairy products, and contained lower amounts of saturated fats, cholesterol and refined grains with a total of 2400 mg/day sodium. The numbers of women whom commenced insulin therapy after dietary intervention, the mode of delivery and prevalence of polyhydramnios were assessed. The length, weight and head circumference of infants were measured during the first 24 h after birth. 46.2% of women in the DASH group needed to have a cesarean section, this rate for the control group was 80.8% (P<0.05). The percentage of those who needed to commence insulin therapy after intervention was 23% for DASH group vs 73% for controls (P<0.05). Infants born to mothers on the DASH group had significantly lower body weight (3222.7 vs 3818.8 g, P<0.05), head circumference (34.2 vs 35.1 cm, P<0.05) and ponderal index (2.50 vs 2.87 kg/m3, P<0.05) compared to those born to mothers on the control diet. Consumption of dietary approaches to stop hypertension for 4 weeks among pregnant women with GDM resulted in improved pregnancy outcomes.

The purpose of this research is evaluating the of microsatellite markers of Masoumin life in primary school textbooks that is done by using content analysis method. For gathering the data in this study categorization system is used. The system developed by researchers and its formal validity was confirmed by the relevant experts and content validity has been calculated using coefficient alpha Cronbach 91%. The results indicate that little attention were paid to the characteristics and Masoumin life in primary school books and many small factors of Masoumin life in primary school books has been ignored and in its place, it is provoking. It is hoped that this research paved the way for programmers to pay more attention to the concepts associated with Masoumin life when developing textbooks.
