Abstract

Background and Objective: 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.
Material and Methods: 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 Levene's tests respectively. The significance of differences between training and supplementation groups was assessed by ANOVA and LSD hock post-test.
Results: 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).
Conclusion: 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.

Abstract

Background and Objective: 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.
Material and Methods: 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 Cronbach'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.
Results: 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.
Conclusion: 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.

Abstract

Background and Objectives: Nowadays, to avoid the use of synthetic preservatives, which do more harm than good, numerous studies are currently focused on using natural ingredients to enhance food product quality and shelf life. Since no study has been conducted on combining coatings with electrolyzed water containing natural antimicrobial compounds, the present study has innovation and priority. In the present study, the effect of chitosan coating prepared through Neutral Electrolyzed Water (NEW) on inhibiting the growth of Escherichia coli O157:H7 inoculated in rainbow trout fillet over 12 days at 4 ˚C was examined.
Material and Methods: Fish samples were allocated into six groups following inoculation with E. coli O157:H7 (final concentration: ~ 105 CFU/g). Treatments included control (CON), distilled water (DW), neutral electrolyzed water (NEW), chitosan 2% (CH), chitosan coating prepared by neutral electrolyzed water (CH/NEW), and neutral electrolyzed water followed by chitosan (NEW+CH). Treatments were kept at low temperature (refrigerator) and counting bacteria was done on 0, 1st, 3rd, 6th, 9th, and 12th days. Data analyses were done through repeated measure ANVOA and Bonferroni post hoc tests.
Results: As indicated by the findings, the reduction rate of EW, CH, CH+WE, and CH/EW samples were 1.04, 1.45, 2.01, and 2.02 log CFU/g compared with the CON, respectively. The highest reduction rate was observed in the CH/NEW sample, due to the antimicrobial activity of chitosan and neutral electrolyzed water.
Conclusion: Chitosan coating can be combined with NEW in fish to increase the safety against pathogenic bacteria and E. coli O157:H7. Therefore, it can suggest the use of these natural antimicrobial compounds in the food industry.

Abstract

Background and Objectives: One of the complicated processes in the Ministry of Health is the process of registering pharmaceuticals .Since there are different soft wares for registration of products, and since parallel services concuss waste of time and money, it is necessary to provide integrated software in the form of services. This goal can be achieved when services are identified and combined in integrated soft wares.
Material and Methods: present study is an applied research, In order to identify the services of an integrated system for recording pharmaceutical supplies, first the Gray-Wolf multi-objective optimization (GWO) algorithm was proposed. Then the values of the algorithm parameters were extracted by the goal-based requirements analysis method and the algorithm was implemented. Finally the best services were extracted by the hierarchical analysis process.
Results: Considering that the results of present study are an operational project in the Ministry of Health, by implementing the algorithm proposed by Gray Wolf, services were identified, which can be used to create integrated software for registering pharmaceutical supplies.
Conclusion: Creating an integrated system for registering pharmaceutical supplies is one of the important challenges of the Ministry of Health. This can be achieved by identifying services and combining these services to create an integrated system.

Abstract

Background: Obesity has been recognized as a global problem that is increasing day by day. Although t Background: Obesity has been recognized as a global problem that is increasing day by day. Although the favorable effects of training and herbal supplements have been reported in this regard, the synergistic effects of the two are still a challenge for researchers. The purpose of this study was to investigate the effect of six weeks of Aerobic Training (AT) and Curcumin (Cu) consumption on adiponectin gene expression in the visceral adipose tissue and some anthropometric indicators of rats fed with High-Fat Diet (HFD).
Material and Methods: In this experimental study, 40 rats with HFD (1.5 mg/kg/day high-fat emulsion) were randomly divided into five groups, including: (1) Healthy Control (HC), (2) High-Fat Diet Control (HFD), (3) HFD+Cu, (4) HFD+AT, and (5) HFD+Cu+AT. Aerobic training was carried out for six weeks, five sessions per week and each session of training was performed 10-50 minutes at a speed of 25-30 meters per minute and a slope of 15 degrees. Also, curcumin was fed to rats by gavage in the amount of 1.5 mg/kg/day. One-way analysis of variance with Tukey's post hoc test was used to analyze adiponectin and ANCOVA test with Bonferroni's test was used to analyze BMI. Data were analyzed in Prism GraphPad PRISM 3.8.3 software (P≤0.05).
Results: Adiponectin gene expression levels in the HFD+AT, HFD+Cu and HFD+AT+Cu groups were significantly higher than the HFD group (P≥0.05). Weight and BMI levels in the HFD+AT and HFD+AT+Cu groups were significantly lower than the HFD (P≥0.05). Also, in the HFD+AT+Cu group, the weight and BMI levels were significantly lower and the adiponectin levels were significantly higher than the HFD+Cu group (P≥0.05).
Conclusion: It seems that exercise training and curcumin consumption both individually and synergistically can be effective in improving anthropometric characteristics by affecting adiponectin levels.he favorable effects of training and herbal supplements have been reported in this regard, the synergistic effects of the two are still a challenge for researchers.

Abstract

Background: In medical research and survival analysis, it is common for an individual or item's failure to be attributable to multiple causes, also known as competing risks. This article focuses on examining the competing risks model as the data increasingly becomes type II censored and randomly removed. The model assumes that the causes of failure are independent and that the lifetimes of individuals are described by the Cox model. At each failure time, the number of items or people removed follows a binomial distribution. The article derives estimators for the indefinite parameters in the model. The study presents a set of detailed data and includes a simulation study that also illustrates the results.
Methods: Different reasons, frequently known as competing risks, are frequently embroiled in an individual's or an item's failure in medical research survival analysis. The competing risks shown under sort II dynamic censoring with random removals are the subject of this research.
We get the maximum likelihood and inexact most extreme probability estimators of the obscure parameters. The asymptotic distribution of the maximum probability estimators is utilized to decide the CIs. Then, Monte Carlo simulations were applied to demonstrate the approach. The analyses were performed utilizing R 4.0.4 software.
Results: For stroke, systolic blood pressure (SBP) and hypertension status are the only significant variables. In contrast, gender, body mass index (BMI), smoking status, the logarithm of urinary albumin and creatinine ratio, and diabetes status are significant variables for coronary heart disease (CHD) and other cardiovascular diseases (CVDs). The results suggest that significant risk factors differ for different types of CVD events.
Conclusion: The outcomes of the simulation study indicate that progressively right-censored type II sampling designs outperformed the usual censored type II sampling designs. Therefore, the estimated parameters on the defined pattern setting are recommended. They can be used in many practical situations when competing risks occur, and progressive censoring could be considered.
