Environmental factors such as electromagnetic waves induce various biological and genetic effects. One of the most important physiological systems involved with electromagnetic fields is the reproductive system. The aim of this research is to investigate blood levels of tumor markers of the uterus and ovaries after receiving short- and mid-term electromagnetic waves emitted from home Wi-Fi equipment.

In this descriptive study, 60 rats were randomly divided into 3 groups. The first group was considered as control, the second group was placed in the vicinity of Iran cell Wi-Fi waves for 1 hour per day for 10 days, and the third group was in the vicinity of these waves for 3 hours per day for 1 month. After certain periods of time, blood samples were taken and the serum levels of cancer antigen 19-9 and cancer antigen 125 were measured using the ELISA method. Data were analyzed by SPSS program using t-test method with significance level of P≤0.05.

The results showed that there was a significant difference in the serum levels of uterine and ovarian tumor markers in the third group that were exposed to WiFi waves for a medium period of time in comparison with the control group and the second group which were affected short-term by Wi-Fi waves (P≤0.05), but the concentration of these tumor markers hadn't significant difference between the second groups and control group (P>0.05).

Exposure to electromagnetic fields, depending on the duration and intensity of the wave, can lead to changes in the level of tumor markers of reproductive system components such as the uterus and ovaries. More extensive studies with more samples and also on human samples are recommended to show the potential risks of exposure to electromagnetic waves on carcinogenesis in females.

Breast cancer is the first fatal disease in women and the second leading cause of death in humans, after heart disease. In approximately 20% of these patients, breast cancer cells have a higher-than-normal level of a protein called human epidermal growth factor receptor 2 (HER2) on their surface. These cancers, called HER2-positive, tend to grow and spread faster than other breast cancers.

This study aimed to evaluate the binding of the peptide LTVSPWY labeled with the HER2 receptor compared to the non-labeled peptide and simulate its docking.

The LTVSPWY peptide was first labeled with the 99-radioactive technetium (Tc-99m) and optimized for molecular docking with the HER2 receptor in HyperChem software. Then, the HEX 6 software was used to check how the compounds were connected to the active site of the HER2. Finally, data was analyzed by HEX, LIGPLOT, and other programs.

During docking in HEX, the labeled peptide showed a good link with the HER2 protein receptor. The energy of this kind of transplantation was higher than the nonlabeled peptide bond with the HER2 protein receptor. In fact, this combination had the lowest level of connection energy with the receptor, which reflects the success of docking.

In the analysis of the post-docking data, we observed the ligand was connected to the HER2 receptor from 5 major sites at different intervals, indicating a suitable bond to the receptor ligand.

Measuring learning skills in the perceptual-motor field is a practical approach to a better understanding of brain functions. The bilateral learning transfer task of the brain is a task with the coordination of two hands and the interaction of the cognitive function of the brain hemispheres. The purpose of the current research is to measure the performance of the mental maze and the learning of bilateral neural transmission in right-handed and left-handed people.

This study was of a causal-comparative type using a random sampling of 40 female and male students of Shiraz School of Medical Sciences. The research tools included Peterson's mental maze, the motor learning test of drawing in the mirror, and Chapman's questionnaire.

The results of the multivariate analysis of covariance showed that the average error and drawing time in the mirror was much lower in the right-handed group than in the left-handed individuals. The right-handed group had a lower mean mental maze error than the left-handed group.

our findings suggest that right-handed people with superior hand skills perform better in bilateral brain transfer learning tasks and draw the figure in the mirror with less time and error. Moreover, they leave behind better skills in spatial memory, which is responsible for storing information in the environment and spatial orientation.

Since new evidence shows the anti-inflammatory effects of selenium, the aim of the present study was to conduct a systematic review and meta-analysis of clinical trial articles on the effect of selenium on serum C-reactive protein (CRP) levels in pregnant women.

In this study, Clinicaltrials.gov, ISI web of science, Cochrane Library, PubMed, and Scopus databases were searched until April 2024, and all randomized clinical trials that investigated the effect of selenium on serum CRP levels in pregnant women were selected. The DerSimonian and Laird random-effects model was used to calculate the overall effect size and heterogeneity. Cochran’s Q-test and I-squared tests were also used to assess statistical heterogeneity between studies.

The results of the meta-analysis conducted on the clinical trial studies showed that selenium supplementation reduced the serum CRP level by 3.99 mg/L, which was statistically significant (confidence interval (CI): -2.30, -5.6; 0.001˂P), and the heterogeneity between studies was also significant (0.001

The results showed that selenium supplementation can significantly reduce serum CRP levels in pregnant women. However, it seems that more studies in different parts of the world are still needed to confirm the beneficial effects or side effects of selenium supplementation on CRP levels among pregnant women due to the significant heterogeneity among studies.

 Thyme have been used as a medicinal plant traditionally for the treatment of digestive system disorders. In present study, the effect of hydroalcoholic extract of thyme on motility of isolated colon of male rat and its interaction with cholinergic, adrenergic and nitic oxide systems was performed.

Ten adult male rats (180- 250 g) were kept in standard condition for one week. Then rats were anaesthetized by ethyl ether and their colon was isolated and divided in to 1 cm strips. The strips were held to a force transducer and inserted to organ bath contained Tyrode solution. The mechanical activity of strips was recorded by Power Lab system with administration of thyme extract (0.0175 mg/ml) and its solvent in experimental and sham groups, and after administration of acetylcholine, epinephrine and L-NAME drugs. Data were analyzed by SPSS software and independent-samples T-test.

 The result showed a significant decrease in the mechanical activity of isolated colon after administration of the effective dose of thyme extract in base line and after of administration of acetylcholine.
There was no significant difference of mechanical activity of the strips at the presence of extract and its solvent after epinephrine and L-NAME administration.

 It can be concluded that thyme extract caused colon relaxation via inhibition of cholinergic pathway and independent from adrenergic and nitric oxide systems.

X-ray is the one of the types of ionizing electromagnetic rays that is widely used in medical and industrial professions, but also has destructive effects. The present study was conducted to determine the effect of X-ray on count and motility of sperm cells of in adult male rat. 40 male rats were divided into two groups, the treatment group with X-ray with variant radiography and control group, respectively. Then, the total number of sperms and their mobility were analyzed by T-test in both groups. The results showed that X-ray was reduced the total number of sperms significantly. The number of dead and immotile sperms increased in X-treated conditions compared to control group significantly. However, the number of active- progressive and slow motion and non- progressive sperms in the X-ray treated group was not significantly different with the control group. It is concluded that X-ray can have destructive effects on male reproductive systems, including reduction sperm count and motility.

Humans live in the world of the waves and energies; the waves that are emitted from various sources and are harmful. One of the possible side effects of radioactive substances on the body is its effect on the amount of sperm production and fertility. In the present study, the effect of iodine 131, was investigated on the motility and number of sperm in male rat.

In this experimental study, 40 adult male rats were divided into two groups: Treatment group treated with oral gavage of iodine 131 and control group. After 24 hours, the number and motility of sperms in both groups, were analyzed by T statistical test. In this study, there was a significant difference in motility and number of sperm between the iodine 131 treatment group and the control group. Moreover, the number of active progressive and dead immotile sperm in the group treated with iodine 131, respectively, showed significant decrease and increase compared to the control group, but, there was no significant difference between the two groups in the less motile and non-progressive sperms. According to the results of this study, considering iodine 131 is used in the treatment of various diseases, thus, treatment with this method can have harmful effects on male reproductive system, such as motility and sperm count

Today, we are dealing with the waves including, the waves emitted from wireless devices connecting to the Internet, which can have a different negative impact on human health. The aim of the present study was investigated the effect of electromagnetic waves emitted from the tablet connected to internet on the movement and number of sperm in adult male rat. 40 male rats were divided into two control and treatment groups with electromagnetic radiation emitted from a tablet connected to the Internet, respectively. Sperm count and sperm motility in both groups were analyzed by T-test. The results showed that the electromagnetic waves emitted from the tablet connected to the Internet caused a significant decrease in the total number of sperms and had a significant effect on sperm motility. In the treatment group with electromagnetic waves from tablet, the number of healthy and damaged sperm had significantly decrease and increase respectively compared to the control group, but there was no significant difference between semi motile sperms in the two experimental groups. It can be concluded that the electromagnetic waves emitted from the internet-connected tablet lead to reduced count and motility of sperm.

Nowadays, the beneficial effects of nanomaterials are accepted in medicine and industry. Considering the increasing use of nanoparticles and their possible toxicity, the effect of nanoparticles on oxidative stress markers was investigated in this study.

The control group received saline, and other three groups received gold, silver, and zinc oxide nanoparticles at a concentration of 100 PPM with IP injection during 28 days. After anesthesia, the tissues of liver, heart and lung were removed, and the activity level of oxidative stress markers was evaluated.
MDA level was significantly increased in zinc oxide treatment group in all three tissues and in gold treatment group in liver tissue. This factor showed a significant decrease in silver nanoparticle treatment in these tissues. The activity of catalase and glutathione peroxidase enzymes in the treatment of silver nanoparticle showed a significant increase. While in the treatment group with zinc oxide and gold nanoparticles, the activity of these enzymes decreased, this decrease was significant only in zinc oxide nanoparticle.
It is concluded that the silver nanoparticle acts as a useful nanoparticle by decreasing MDA and oxidative stress and inducing antioxidant enzymes, while the effect of zinc oxide nanoparticle shows its toxicity.

Infertility is a personal crisis. There are different assisted reproductive techniques in the treatment of infertility. Anxiety and stress have been shown to be markedly higher in infertile couples. This study was aimed to compare the frequency and intensity of stressors in infertile couples undergoing intrauterine insemination (IUI) treatment, Intra-cytoplasmic sperm injection (ICSI) treatment and without treatment (control group).
Thirty seven infertile couples undergoing IUI, ICSI and without treatment were selected by non-random convenient sampling from the cases admitted to Rooyan Infertility Clinic. They completed demographic information sheet, and the Stressors Scale. The results showed that there was no significant correlation between duration of infertility with frequency and intensity of stressors. There was no significant correlation between frequency and intensity of stressors with infertility factors. There was also no significant difference in the frequency and intensity of stressors between men and women. There were no differences in the frequency and intensity of stressors between ICSI and IUI with control group. Data showed that there was a significant difference in the frequency of stressors with the group of IUI treatment as well as in the frequency of stressors between ICSI and IUI with control group. Findings demonstrated that there was significant difference between IUI with and without ICSI groups in the frequency and intensity of stress.
IUI, ICSI and control groups as the assisted reproductive techniques can be stressful. Long-term planning of mental health services for infertile couples, identifying couples at risk, convincing couples to refer for psychological assessment, psychotherapy by clinical psychologists, and drug therapy by psychiatrists are suggested.

Herbal medicines have been used as a therapeutic method for a long time. Ginger with a scientific name of Zingiber officinale from family of Zingibracea، is a one of the medicine herbal. It has a widely use in the traditional medicine and addition to its utilization as a dietary supplement، it is used in medicine frequently since ancient times. It has been used previous the decades، due to the diversity of its active components in the treatment of various diseases. The therapeutic spectrum of Ginger is in the treatment of rheumatism، cramps، asthma، nausea، vomiting، hypertension، dementia، fever and infection. The pharmacological actions of Ginger include antioxidant، anti-tumor، anti-apoptosis، anti-inflammation، anti hyperglycemia، anti cough and anti colds effects. The purpose of this study was to review of recent research، also investigation on the photochemical، pharmacological، and physiological properties of Ginger and its biological active components.

Ginger is a plant that was used for bronchodilation from the ancient times. The aim of this study was to evaluate the effect of hydroalcoholic extract of Zingiberofficinale on mechanical activity of isolated trachea and its interaction with nitric oxide system. 15 adult male rats after adapting with their environment for one week were anesthetized with intraperitoneal injection of sodium pentobarbital and theirs trachea were isolated and divided into 3-mm strips. Then the isolated tracheal strips were divided into control and experimental groups that were inserted to organ bath contained krebs solution. The mechanical activity of trachea was recorded by power lab system. After establishing the basic conditions, in experimental group, hydroalcoholic extract of ginger (0.3mg/ml) and to control group in the same conditions, ethanol 70% as solvent was added. Then, mechanical activity of each group in the presence of L-NAME was recorded. The data were analyzed through paired sample t- test at P ≤ 0.05 as the significant level. The results showed significant decrease of mechanical activity of tracheal strips in the group which was exposed to ginger. These effects were not reversed after administration of L- NAME in comparison with the control group. It can be concluded that ginger has an inhibitory effect on mechanical activity of trachea which is probably independent from nitric oxide system.
