Scientific evidences indicate on beneficial effects of ginger on cardiovascular disease. This study was to investigate the effect of a short period of intense intermittent exercise and ginger on selected cardiovascular risk factors in male athletes.

The present quasi-experimental study performed on 46 male soccer players (40-50 years old) with pre-test and post-test design, divided into four groups as exercise (n=12), exercise and ginger (n=10), ginger (n=12) and control (n=12). Severe intermittent training was performed for four weeks, accompany with ginger (3,000 mg daily). Serum C-reactive protein (CRP) levels and systolic and diastolic blood pressure (BP) were measured in both pre-test and post-tests. To analyzing data, covariance analysis test with Bonferroni post hoc test and paired t-test were used in SPSS software.

Concurrent exercise and ginger intervention significantly decreased serum CRP (P=0.001), diastolic blood pressure (P=0.001) and resting systolic (P=0.001) compared to the control group. In addition, significant improvement in baseline serum CRP (P=0.04), systolic BP (P<0.001) and resting diastolic BP (P=0.001) was observed in the Ginger + exercise group after four weeks.

Concurrent ginger consumption and intensive aerobic exercise have a positive effect on cardiovascular risk factors and can be used as non-pharmacological solutions to prevent cardiovascular diseases.

Given the increasing consumption of fast foods, this study was aimed to determine the amount of consumption of fast foods in students and its possible relationship with depression and body mass index in students.

This cross-sectional study was conducted in 2016. The study population consisted of 600 medical students who were selected using stratified random sampling. In this study, demographic and standard questionnaires were used to measure depression (Beck's tool) and food intake. The data were analyzed using chi-square and independent t-test in SPSS software.

73% of students have been consumed fast foods at least one per week. The majority of students with moderate to high intake of fast foods were single (91%) and male (54%). There was a relationship between fast foods and demographic variables and body mass index. Also, higher consumption had a significant relationship with depression in evaluated medical students (P<0.05).

Higher intake of fast foods has a significant relationship with obesity and depression in students. Thus, it should be carefully monitored to prevent of negative impacts on students' education.

Understanding risky behaviors of teenagers as a prerequisite, not as deviant behavior, is essential. The present study was aimed to finding the possible relationship between school environment with risky behaviors and addiction among high school students.

This study was a correlational research project contributing all high school students in the academic year of 2018-2019 in Zahedan city. Participant were selected from a sample size by multi-stage cluster method using Cochran's formula. Data collected via Alfred et al.'s (2004) classroom and school environment, the risk of Iranian adolescents (2011), and addiction predisposition (1991) questionnaires over a three-week period and then analyzed using correlation coefficient and linear regression tests in Spss software.

There was a positive and significant relationship between classroom and school environment with high-risk behaviors (r=0.20) at 95% confidence level. There was also a significant relationship between addiction talent and classroom environment (p=0.23) at 95% confidence level.

Preventing high-risk behaviors is always easier, less expensive, and more effective than treating them. Therefore, securing school's environment can reduce the risk of risky behaviors in students.

Cancer is one of the leading causes of human death in worldwide and imposes a huge economic burden on the health providing systems in countries. So today, researchers are looking for new anti-cancer drugs with more potency and fewer side effects. Worldwide, the development of anti-cancer drugs from natural resources is on the rise. Animal venom is one of the most important and valuable biological resources, and some scientists believe that it is one of the future hopes of humans to cure some incurable diseases, including cancer. These biological compounds include a variety of neurotoxins, enzymes, peptides, carbohydrates, minerals, and proteins with specific biological and chemical activities that have effective peptides such as hyaluronidases, phospholipases, sphingomyelinazes, cholinesterase, and alkaline phosphatase and so on. In fact, these biologic features make them an attractive issue in developing anti-cancer agents. In this study, animals who their venom have these biological characteristics have been studied.

Academic studies provide solutions for educational, research, and health problems. This study was investigated the inhibitors of these research activities from the perspective of paramedical students.

This was a cross-sectional descriptive-analytical study contributing 152 students who had completed at least one year of study. The data was collected through a questionnaire consisting of three sections as demographic information, personal barriers and organizational barriers. Then, they were analyzed in SPSS 22 software using descriptive and analytical statistics methods.

61.2% of the participants were women. 83.9% of the student who did the research, had a history of research workshops. According to the T-pair test, a significant difference was observed between mean score of organizational disincentive (51.95±9.89) and personal disincentive factors (46.8±10.41) (P=0.00). In other words, organizational disincentive factors have been greater than individual one. Also, from the students' point of view, the lack of familiarity with statistical principles and the greater importance of clinical services than research services were the most important personal and organizational disincentive factors, respectively.

Considering the most important organizational and personal disincentive factors barriers obtained in this study, it can be stated that the importance of research in providing better clinical services, providing research facilities and also holding higher quality research workshops can reduce students' research problems.

Chronic hyperglycemia during diabetes is the leading cause of nerve tissue damage and neuronal dysfunction, which is defined as diabetic neuropathy. This activation, through the activation of a wide range of destructive cellular markers in the brain and then a defect in the learning and memory process, leads to a kind of forgetfulness called diabetic dementia. Increased production and accumulation of free radicals that lead to oxidative damage in brain tissue is one of the key pathways to damage neurons and nerve tissue. In addition to damaging cellular structures, these radicals induce various brain pathways, including PI3-kinase, AKT, and ERK1/2, by inducing the production of various inflammatory cytokines and mTOR (mammalian target of rapamycin) proteins in the brain. It then plays a key role in the destruction of neurons and dementia caused by diabetes by hyper-phosphorylation of tau protein and accumulation of beta-amyloid proteins. Fluorine nanoparticles (C60), as a powerful antioxidant and free radical scavenger, can prevent the accumulation of a variety of free radicals in brain tissue during diabetes. The use of these nanoparticles can prevent neuronal damage and diabetic neuropathy by inhibiting destructive signaling pathways that are activated by increased production of free radicals. Therefore, due to the lack of significant toxicity of these nanoparticles in biological environments, the use of these agents can be considered as a new treatment to maintain brain health and prevent neuropathy and dementia during diabetes.

Upon spread of Covid-19 from China to other countries, medical staff at health care providing centers for special diseases have been challenged to identify suspected cases of Cuvid-19 among febrile patients with acute respiratory infections. Our aim in this study was to investigate hospital emergency management strategies during the epidemic of covid-19. In this study, all researches related to covid-19 management and all the strategies have been recommended and used in China and the World Health Organization were reviewed, and finally the appropriate hospital strategies to deal with this disease were examined. The results of this study introduce solutions for triage management, acute respiratory disease clinics, patients' quarantine in health care providing centers, procedures and experiments, staff, call tracking, health care system and general education (non-pharmacological interventions).

Providing high quality services in hospitals increases patient loyalty and improves hospital performance. This study analyzed the relationship between the quality of hospital services and patient loyalty in Iranian hospitals.

This study was conducted using a meta-analysis method. For this purpose, all published articles on the relationship between the quality of hospital services and patient loyalty in Iranian hospitals in the period from 2012 to the end of March 2017 were reviewed in five databases and a search engine. Finally, 11 papers were included in the study, which were analyzed using Comprehensive Meta-Analysis software.

The results showed that the mean effect of hospital services quality on patient loyalty was 0.66, which was highly evaluated based on Cohen's interpretive system. Based on the randomized model, the effect size in inpatients, outpatients and all patients was 0.74, 0.45 and 0.66, respectively. On the other hand, the size of the effect was 0.76in the army forces hospitals, 0.71 in the private hospitals, 0.62 in the public hospitals and 0.55 in the public and private hospitals. The size of the effect based on the random model in Tehran province and other provinces was 0.84 and 0.64, respectively, which was significant in all variables (P = 0.0001).

Providing quality services affects patients' loyalty. Therefore, hospital managers, while planning to improve the quality of services, should provide the ground for paying attention to the dimensions and components of increasing patient loyalty to the hospital.
