Aims: Newborns are more sensitive to pain than adults and are more susceptible to the long-term complications of pain. So, it is necessary to use procedures for reducing pain in newborns. The aim of this study was to determine the effect of local heat on the pain intensity of heel-blood sampling in the term newborns.
Material & In this randomized controlled clinical trial study, in 2012, 63 healthy 3 to 5-day newborns who were referred to Shahid Delkhah Health Center in Ferdows were selected by random sampling method and randomly divided into 3 groups (21 people in each group): test (heat), placebo (sound) and control. The pain intensity of newborns before, during and after heel-blood sampling was evaluated. The data collection tools were demographic questionnaire and Neonatal Infant Pain Scale (NIPS). Data were analyzed by SPSS 14.5 software and chi-square test, one-way ANOVA, Tukey's post hoc test, and ANOVA with repeated observations.
Finding: The mean pain intensity in the three groups was not significantly different before intervention (p=0.86), but the mean pain intensity was lower in the test group than in the other two groups (p=0.006). After heel-blood sampling, the mean pain intensity was the least in the test group and was the most in the control group (p Local heat during and after heel blood sampling decreases pain intensity in the term newborns.

Aims: The high concentration of Interleukin-1 beta (IL-1β) and Tumor Necrosis Factor- α (TNF-α) is an important risk factor for developing cardiovascular disease. The purpose of this study was to investigate the simultaneous effect of High-Intensity Interval Training (HIIT) and the use of flaxseed oil with different doses on the serum levels of TNF-α and IL1β in rats.
In this experimental study, 30 Wistar rats were randomly divided into six groups: control, training, 10mg/kg supplement, 30mg/kg supplement, training with 10mg/kg supplement and training with 30mg/kg supplement. The groups performed High-Intensity Interval Training (HIIT) for 10 weeks and received flaxseed oil extracts. Data were analyzed by one way ANOVA and LSD post hoc test.
Findings: Serum levels of IL1β in the training group and training groups with doses of 10 and 30mg/kg of extract were significantly lower than the control group. Serum levels of IL1β in the training group with 30mg/kg of extract, was significantly lower than group with 10mg/kg of extract. Also, serum levels of TNF-α in the training group, training groups with doses of 10 and 30mg/kg of extract and group with 30mg/kg of extract were significantly lower than the control group. Serum levels of TNF-α in the training group with 30mg/kg of extract were significantly lower than other groups (p High-Intensity Interval Training (HIIT) and consumption of flaxseed oil for 10 weeks have interactive effects on reduction of serum levels of TNF-α and IL-1β in rats.

Aims: Wet-cupping as a therapeutic method has been recommended to be done on certain days based on authentic sources of traditional medicine in Iran. The purpose of this study was to determine the relationship between amount of exited blood during wet-cupping with patient's individual conditions and the time it was performed.
Instruments & In this descriptive cross-sectional study, 391 men who were referred to a cupping center in Saveh city in the spring of 2016, were selected by simple sampling and wet-cupping in the position between the two scapula was performed. The research instrument was a questionnaire including demographic characteristics, date of reference (day, month and year), age, height, weight and amount of exited blood during the wet-cupping in gram. Data were analyzed by SPSS 16 software and using chi-square test, paired t test and one-way analysis of variance.
Findings: The means of age, weight and body mass index were significantly related to the mean of amount of exited blood during wet-cupping (p0.05), but the amount of exited blood was higher in people with previous history of wet-cupping than those without previous history (p Individual characteristics such as age, weight, body mass index, cause of referral and previous history of wet-cupping affect the amount of exited blood during wet-cupping, but the time of wet-cupping (day and month) does not affect the amount of exited blood.

Aims: Blood neurotrophins, such as Brain-Derived Neurotrophic Factor (BDNF) and Insulin-like Growth Factor 1 (IGF-1), mediate exercise- induced health benefits in humans. The purpose of this study was to compare the response of BDNF and IGF-1 to different endurance training intensities in runner men.
In this semi-experimental study with pre-test-posttest design in 2015, 10 people of male runners from Gorgan were selected through purposeful and accessible sampling. The endurance training protocol was 6 km running with moderate (70-75% of heart rate reserve) or severe (80-85% of heart rate reserve) intensity, which was performed within a week's interval. Fasting blood samples were collected before and immediately after both acute training sessions and serum levels of BDNF and IGF-1 were measured by ELISA and radioimmunoassay enzyme. Data were analyzed by SPSS 20 software using independent t-test and paired t-test.
Findings: Both acute endurance training significantly increased serum levels of BDNF and IGF-1 in runners, but high intensity endurance exercises increased BDNF levels in comparison with moderate intensity (p0.05).
Serum BDNF response in endurance athletes is affected by the intensity of exercise, so that the effect of high intensity endurance training on BDNF levels is greater than moderate intensity exercise, but the response of IGF-1 to acute endurance training is independent of the intensity of exercise.

Aims: Breast cancer is the most common cancer among women that usually begins with abnormal growth and division of different breast cells. There is some evidence that there is an inverse relationship between levels of antioxidants and the risk of breast cancer. The purpose of this study was to investigate the effect of 8 weeks resistance training on some antioxidant/oxidative indexes in postmenopausal women with breast cancer.
In this semi-experimental study, in 2014, 30 postmenopausal women with breast cancer in Khorramabad city were selected by available sampling method and randomly divided into 2 groups: experimental group (n=16) and control group (n=14). The experimental group performed resistance training for 8 weeks, which started from 30% 1RM (one repetition maximum) and reached 45-50% 1RM at the end of the eighth week. Blood samples were taken from subjects for the measurement of superoxide dismutase (SOD), glutathione peroxidase (GPX) and malondialdehyde (MDA) serum levels, 48 hours before and after the training protocol. Data were analyzed by SPSS 19 software using independent t-test and dependent t-test.
Findings: After performing 8 weeks of resistance training, serum levels of SOD and GPX significantly increased and MDA levels decreased significantly (p0.05).
Resistance training for 8 weeks increases antioxidant indexes and decreases oxidative indexes in postmenopausal women with breast cancer.

Aims: Chronic inflammation in the body can be a stimulant for insulin resistance and type 2 diabetes. C-reactive protein (CRP) is an indicator of systemic inflammation and Interleukin-10 is one of the most important anti-inflammatory cytokines. The purpose of this study was to compare the effect of two exercise training protocols (aerobic and resistance exercises) on levels of Interleukin-10, CRP and insulin resistance index (HOMA-IR) in women with type 2 diabetes.
In this semi-experimental study with pre-test and post-test design in 2015, 24 women with type 2 diabetes who referred to diabetes control centers in Tehran city were selected by random sampling method and randomly divided into three groups (n=8): aerobic training group, resistance training group and control group. Exercise training was conducted in aerobic training group with 50-65% of maximum oxygen consumption (Vo2max) and in resistance training group with intensity of 60-70% one repetition maximum (1RM) for 10 weeks. Before and after exercise, anthropometric indices and blood samples of subjects were evaluated. Data were analyzed by SPSS 20 software and using repeated measures analysis of variance.
Findings: After 10 weeks, levels of Interleukin-10 in the aerobic training and resistance training groups were significantly increased and insulin, fasting glucose and insulin resistance index decreased significantly, but CRP concentration and body fat percentage decreased only in the resistance training group (p Both exercise training protocols improve fasting blood glucose, insulin, insulin resistance index and increase levels of Interleukin-10 in type 2 diabetic women. Resistance training also decrease levels of CRP.

Aims: Silver nanoparticles, through free radical production, can cause oxidative stress. The purpose of this study was to determine the effect of crocin on Bax/Bcl-2 ratio, lipid peroxidation and antioxidant enzymes activity in liver tissue of chick embryo treated with silver nanoparticles.
In this experimental study, 45 Ross 308 Fertilized chicken eggs were randomly divided into five groups (control and experimental groups). On day 10 of incubation, the control group received 0.5 ml of saline solution in an amniotic sac of embryos and experimental groups 1, 2, 3 and 4 were treated with one injection of 0.5 ml of silver nanoparticle 200 ppm and a size of 60 nm. On day 12 of incubation, the experimental groups 2, 3 and 4 were treated with crocin 0.5 mg/ml in concentrations of 100, 200 and 300 μg/ml. On day 20 of incubation, levels of Bax, Bcl-2, malondialdehyde (MDA) and antioxidant enzymes of the liver tissue were measured. Data were analyzed by SPSS 20 software, using one-way ANOVA and Tukey's post hoc test.
Findings: In the group of silver nanoparticles compared to the control group, the levels of Bcl-2 and antioxidant enzymes decreased and Bax and malondialdehyde levels increased. In groups of silver nanoparticles with concentrations of 100, 200 and 300 μg/ml of crocin compared to the group of silver nanoparticles alone, the levels of Bcl-2 and antioxidant enzymes increased in dose-dependent manner, and Bax and malondialdehyde levels decreased in dose-dependent manner (p Dose-dependent injection of crocin decreases oxidative stress, lipid peroxidation and apoptosis in liver tissue of chick embryo by decrease of toxicity of silver nanoparticles.

Aims: Family members are the main components of the care system for injured spinal cord patients. Taking care of such patients is a tense responsibility. The purpose of this study was to investigate the relationship between humor and subjective well-being with regard to the mediating role of resilience in caregivers of patients with spinal cord injury.
Instruments & In this descriptive-correlational study, 219 caregivers of spinal cord injured patients referred to Borna Scientific-Sport Institute in Isfahan in 2016 were selected using available sampling. Data were collected using Subjective Well-Being Scale (SWBS), Resilience Scale and Sense of Humor Questionnaire (SHQ). Data analysis was performed by Amos 18 software, using Structural Equation Modeling (SEM) and Bootstrap test.
Finding: Correlation between humor and resilience with subjective well-being was significant (p Psychological resilience in relationship between humor and subjective well-being as mediator plays an important role in improving the psychological state of caregivers of patients with spinal cord injury.

Aims: Leptin is one of the most important fat-derived hormones. Several studies have shown that serum leptin levels in systemic inflammatory diseases are reduced. The aim of this study was to evaluate the serum leptin levels in three groups: patients with active pulmonary tuberculosis (TB), patients with non-pulmonary infections (acute pneumonia) and normal people.
In this cross-sectional study, in 2010, 40 patients with active pulmonary TB (case group) and 40 patients with non-pulmonary infections (positive control group) admitted to Boo-Ali hospital in Zahedan and 40 healthy subjects (negative control group) were selected using easy access and serum leptin levels were evaluated by ELISA. Data were analyzed by SPSS 18 software and one-way ANOVA.
Findings: The mean of serum leptin levels in patients with non-pulmonary infections (p=0.030) and in patients with active pulmonary TB (p=0.004) were significantly lower than normal group, but the mean of serum leptin levels in patients with active pulmonary TB and patients with non-pulmonary infections were not significantly different (p=0.555).
Serum leptin levels are lower in patients with active pulmonary tuberculosis and in patients with non-pulmonary infections than in normal people, but there is no difference between patients with active pulmonary tuberculosis and patients with non-pulmonary infections. Therefore, serum leptin levels are not an appropriate marker for the differentiation of active pulmonary tuberculosis from pulmonary infections (acute pneumonia).

Aims: Diabetes, as a common metabolic disease, can have significant psychological consequences and cause problems in daily life. The purpose of this study was to investigate the mediator role of sense of coherence in the relationship between duration and number of physical complications of diabetes with mental health in patients with type 2 diabetes mellitus.
Instruments & In this descriptive-correlational study, 150 patients with type 2 diabetes mellitus referred to Parsian Diabetes Clinic of Mashhad in 2015 were selected using available sampling. Data were collected using a checklist of demographic information and physical complications of diabetes, Sense of Coherence Scale (SOD) and General Health Questionnaire (GHQ). Data were analyzed by Lisrel and SPSS 18 softwares, using Pearson correlation coefficient and path analysis method.
Findings: The duration of disease, the number of physical complications of diabetes and the lack of mental health had a negative and significant correlation with the sense of coherence. There was a positive and significant correlation between duration and number of physical complications of diabetes mellitus with mental health problems (p Sense of coherence as a mediator in the relationship between duration of disease and number of physical complications with mental health in type 2 diabetic patients plays an important role in controlling the physical and psychological complications of diabetes.

Aims: Premature infants need breastfeeding milk in infancy in order to achieve optimal growth more than ever and not having enough milk in breast feeding, is a common problem for women who have premature infants. Reflexology massage is one of the proposed treatments to help with this issue. The current study is aimed to determine the effect of reflexology on milk production in mothers with premature infants.
In this randomized clinical trial, 30 mothers with premature infants admitted to Shohada Hospital in Quchan city, in 2016, were selected through convenient sampling and randomly divided into intervention and control groups. The intervention group received foot reflexology massage for 3 consecutive days for 20 minutes and the control group received routine care only. The volume of milk was measured before and 30 minutes after massage on the first and third day of the study. Data were analyzed by SPSS 22 using Chi-square, independent t-test and repeated measures analysis of variance.
Findings: There was no significant difference in the mean volume of milk on the first day after reflex massage between the intervention group and the control group (p=0.79), but on the third day, there was a significant difference in the mean volume of milk after reflex massage between the intervention group and the control group (p=0.02). The difference in mean volume of milk on the third day, after intervention compared to before intervention was not significant (p=0.187).
Reflexology massage is not effective on milk production in mothers with premature infants.

Aims: Diabetes is a metabolic disorder that results in hyperglycemia due to non-regulation of blood glucose. The aim of this study was to evaluate the hypoglycemic interactive effects of Ginger extract and endurance training in diabetic rats.
In this experimental study, 40 streptozotocin-induced diabetic rats were randomly divided into four groups (control, endurance training, Ginger extract and endurance training with Ginger extract). The training groups ran 8 to 16 meters per minute for four weeks, five sessions per week, and each session for 30 minutes on treadmill. Ginger extract groups received daily 100 mg/kg Ginger extract intraperitoneal for four weeks. At the end, levels of fasting glucose, insulin and insulin resistance were measured. Data were analyzed by SPSS 21 software using dependent T-test, one way ANOVA and Tukey's post hoc test.
Findings: Levels of fasting glucose, insulin and insulin resistance in endurance training group, Ginger extract group and endurance training with Ginger extract group were significantly lower than control group. Also, levels of fasting glucose, insulin and insulin resistance in endurance training with Ginger extract group were significantly lower than endurance training group and Ginger extract group (p Endurance training with use of Ginger extract has hypoglycemic interactive effects on improving glucose indices in diabetic rats, leading to a decrease in levels of fasting glucose, insulin and insulin resistance in streptozotocin-induced diabetic rats.

Aims: Angiogenesis and angiostasis processes mean the forming and preventing the formation of a new capillary from pre-capillary, respectively. Angiogenesis due to exercise is controlled by the balance between angiogenic and angiostatic factors. Angiogenesis due to exercise training by increasing capillary density in muscle fibers improves the transfer of oxygen and nutrients to the muscle. The aim of this review was to evaluate the response of each of these angiogenic and angiostatic factors to exercise.
Vascular endothelial growth factor, transforming growth factor-β, angiopoiten and matrix metalloproteinase are most important angiogenic factors that show an up-regulated response following exercise. In contrast, angiostatin, endostatin, thrombospondine 1, and tissue inhibitor of metalloproteinase act as most important angiostatic factors. Although their functions in cell culture are cleared, further research is still necessary to obtain more consistent conclusions about response of inhibiting factors in both of physiologic and pathologic conditions following exercise.
