Hypertension is a major risk factor for the cardiovascular diseases. One of the factors contributing to blood pressure is peripheral vascular resistance. Vascular stiffness plays a key role in developing the hypertension, leading to increased systolic blood pressure and pulse pressure. from Avicenna s perspective, the blood pressure caused by 1- Increased blood volume 2- Warm heart dystemperament which leads to the hyperactivity of heart pump and increased cardiac output 3- A vascular disorder called "Tasallob Sharaeen”  "atherosclerosis".  So, one of Avicennachr s recommendations for the prevention and treatment of hypertension is the consumption of Moisturizing foods and beverages and fruits. One of these moisturizing products which are very useful is “whey Protein”. It seems that by studying ancient Iranian medicine s general books, new and effective solutions can be provided in the prevention and treatment of diseases.

Foodborne illness is a common public health problem. Surfaces and equipment used in food production are involved in the spread of foodborne pathogens. The aim of this study was to evaluate and compare the antimicrobial effect of Vinoxide and Sanisept against Staphylococcus aureus strains isolated from food production lines.

In this descriptive study, 110 samples were taken from various equipment and surfaces used in food workshops and local kitchens. After identification of S. aureus by microbiological tests, the antimicrobial effect of two disinfectants (Vinoxide and Sanisept) on the isolates was assessed using the dilution-neutralization test according to the protocols of Iranian National Standards No 2842 and 9899.

Of 110 collected samples, 21 (19.1%) were contaminated with S. aureus. The results showed that 19% and 38% of S. aureus isolates were able to grow after treatment with Vinoxide and Sanisept, respectively. Although Vinoxide had better bactericidal effect than Sanisept, both disinfectants could significantly reduce the number of live S. aureus isolates (P<0.05).

Sanisept and Vinoxide have significant inhibitory effects on S. aureus isolates, but due to the unpleasant odor of Vinoxide, the use of Sanisept is recommended in food industry.

Diabetes is one of the health problems in all societies. The aim of the present study was to investigate the effect of a period of training at different temperatures on the gene expression of GLUT_4 and insulin receptor in the brown adipose tissue of diabetic rats.

In this experimental study, 21 diabetic rats were randomly divided into 3 groups of 7 animals, including: (1) control (C), (2) swimming training at 5° C (S5ºC), and (3) swimming training at 36° C (S36ºC). Water swimming training was performed at 5±2° C and 36±2° C for six weeks, 5 sessions per week and 2-4 minutes per session. Data were analyzed using one-way analysis of variance and Tukey’s post hoc test at the significance level of p≤0.05.

The gene expression of GLUT4 and insulin receptor in the S5º C and S36º C groups was significantly (P = 0.0001) higher than the control group. Also, the gene expression of GLUT4 in the S36º C group was higher than the S5º C group (p = 0.001), and the expression of insulin receptor in the S5º C group was significantly (p = 0.001) higher than the S36º C group.

Swimming training at 5º C and 36º C significantly increased the gene expression of GLUT4 and insulin receptor in the brown adipose tissue of diabetic rats.

Clinical studies have indicated, that exercise activity and supplementation may have different effects on heart function and health. The aim of this study was to assess the effects of weight training with whey protein supplementation on ANP, BNP, and Galactin-3 in 60-65 years old sedentary men.

This study was based on a quasi-experimental design. The sample population was selected from volunteers out of the Kahrizak charity sanitarium of the Tehran province. Forthy men were randomly assigned to 4 groups (control, exercise, whey protein, and exercise + whey protein). Whey protein and exercise + whey protein groups were asked to consume whey protein. Training protocol lasted for 6 weeks. Blood levels of ANP, BNP, and Galactin-3, before and after the study were measured. Normality and variance heterogeneity was assessed using Shapiro-Wilk and Levenechr('39')s tests respectively. The significance of differences between training and supplementation groups was assessed by ANOVA and LSD hock post-test.

The results showed that weight training program and in combination with whey protein supplementation significantly reduced Atrial natriuretic peptide (P=0.001), Brain natriuretic peptide (P=0.001), and Galactin-3 (P=0.001), compared to the control group (P<0.01).

The reduction of cardiac injury indices and structural and physiological recovery and the increase of cardiac function have been affected by the synergy of his training and protein.

Research on how to participate in recreational sports and the factors influencing the choice of these sports are too meager in health areas. Therefore, the aim of this study was to analyze the effect of recreational sports development on health and Participation of students in sports activities.

The present study is descriptive-correlative in terms nature, and is applied in terms of purpose. The statistical population of the study consisted of all university students in Bushehr city, from whom the study sample was picked based on stratified random selection (N=384). To collect data, a researcher-made questionnaire was used and the validity of the questionnaire was confirmed by twelve experts. Also, its reliability was calculated using Cronbachchr('39')s alpha (r=0.91) and composite reliability. In order to analyze the data and examine the fit of the model, structural equation modeling was implemented using PLS3 and SPSS24 software (p≤0.05). The results of path analysis revealed that the development of recreational sports has a direct and positive correlation with physical health. Also, the effect of recreational sports development on students’ participation in sport was significant.

The results of factor analysis showed that physical health, mental health, and physical fitness had a significant role in explaining the physical health variable. Also, social aspects, athletic interest and pleasure, athletic performance and athletic skill acquisition had a determining role in the sport participation variable.

According to the findings, it can be deduced that in the attention to and research on sport participation in health area, simply reliance on individual characteristics results in Halo error (based on behavioral theories), and to avoid it, it’s better to notice the effects of other variables, such as the athletic interest and pleasure, athletic performance, and athletic skill-acquisition.

Downscale outcome in assisted reproductive techniques (ART) is associated with lipid peroxidation. Melatonin may have beneficial effects against lipid peroxidation and oxidative stress. This work was aimed to evaluate the ameliorative capacity of melatonin versus the passage of time and lipid peroxidation on sperm parameters from the men with ATS in the ART process.

Semen samples were collected from 50 asthenoteratozoospermic (ATS) men. Samples were divided into control and melatonin group. The test group were incubated with 6 mM melatonin at 2, 4, 6, and 24 hours. Then total and progressive motility, membrane integrity, and Malondialdehyde levels (MDA) were evaluated. Statistical analysis was carried out by SPSS software (repeated-measures ANOVA).

In the control group, total (p<0.01) and progressive (P<0.05) motility and also, membrane integrity (P<0.03) significantly decreased although, MDA levels of sperm significantly increased (*P<0.04). Moreover, in the melatonin group, the mentioned parameters significantly compensated compared to the control group (P<0.05).

In the outcome, melatonin in vitro treatment paves the way for motility and membrane integrity up-regulating in the ATS men.

Trimethyltin (TMT) is an organotin neurotoxin which causes cognitive disorders by the induction of selective damage in hippocampus. The present study evaluates the effect of 8-week swimming exercise (EX) and Gallic acid (GA) for working and avoidance memory, hippocampal oxidative stress indices and brain neurotrophic factor expression (BDNF) in rats after TMT intoxication.

In this experimental study, 40 Wistar mature male rats were randomly put in 5 groups of control, TMT+NS, TMT+GA200, TMT+EX, TMT+GA200+EX. 24 hours after TMT intoxication (8mg/kg), 8 weeks of swimming exercise (3 sessions per week), and treatment with GA (200mg/kg) were done. Then, the evaluation of working and passive avoidance memory was performed respectively by the use of Y maze and shuttle box. Hippocampal level of catalase (CAT), total antioxidant capacity (TAC) and BDNF were done by ELISA method, and content of malondialdehyde (MDA) was performed by thiobarbituric acid (MDA). Statistical differences between groups were analyzed by two-way ANOVA and Bonferroni post hoc test.

The significant decrease in the percentage of alteration behaviors, latency time to the dark room, along with BDNF, CAT, TAC and increase of MDA were seen in TMT+NS group compared to control group (p<0.01). Swimming exercise in the interaction with GA ameliorates working and avoidance memory by increasing BDNF, CAT, TAC, and decrease of MDA compared to TMT+NS group (p<0.05).

It seems that swimming exercise and GA administration improves cognitive symptoms following TMT intoxication simultaneously by decreasing oxidative stress and increasing BDNF expression.

The COVID-19 outbreak has led to increasing global concerns about infection control. Amid this pandemic, dentistry could be considered as one of the most high-risk medical sectors for health workers due to the high exposure to patients infected with this deadly virus.After the decline of the steep prevalence of COVID -19 cases, the dental associations have allowed dental offices to reopen under special circumstances by taking the necessary precautions and following the prescribed guidelines to keep both the dentists and their patients safe and healthy during the treatment.The aim of this review is to present a policy to manage and facilitate the dental procedures in the dental practice routine amid coronavirus by focusing on the patients’ risk level in order to keep the possibility of COVID -19 transmission to a minimum.
