Background and Objective: Gestational diabetes mellitus (GDM) is usually a disease caused by inadequate insulin production in pregnant women. GDM induces abnormal fetal growth.This study was done to evaluate the BMP2 and BMP4 genes expression in the development of the embryos heart in induced gestational diabetes of C57BL/6 mice.
Methods: In this experimental study, 8-week old adult C57BL/6 mice were randomly divided into diabetic and control groups. After mating of animals, the dams in diabetic group were received a single dose of 150 mg/kg/bw of streptozotocin on gestational day 1 of pregnancy, intrapereatonally. After 11.5 days of pregnancy, the embryos of both groups were extracted and heart tissue was extracted. RNA total tissue of the heart was extracted by trazole. After extracting RNA, expression of BMP2 and BMP4 genes in the heart of both groups was estimated by Real-time PCR.
Results: There was no singnificant diference in expression of BMP2 and BMP4 genes in the heart of 11.5 days of embryos in gestational diabetes mellitus group and control group.
Conclusion: Gestational diabetes mellitus had no effect on the expression of BMP2 and BMP4 genes in the development of the embryos heart.

Background and Objective: Gestational diabetes (GDM) is a metabolic disorder which is caused by insufficient secretion of insulin. GDM is a risk factor for embryo during pregnancy and it is possible leads to congenital heart defects (CHD). Some of these defects may be due to a change in the expression of some of the important structural genes in the heart. Desmocollin 2 and collagen structural genes have important role in the cell adhesion of the cardiomyocytes.This study was done to determine the effect of gestational diabetes on expersion of desmocollin 2 and col5a2 structural genes in C57BL mouse embryo heart.
Methods: In this experimental study, 12 adult female and six adult male C57BL mice were used.After mating of the animals and observation of the vaginal plug, the female mice with vaginal plug were randomly divided into diabetic and control groups. At the first day of pregnancy, Induction of gestational diabetes mellitus in dams in the diabetic group was performed by the intraperitoneal (IP) injection of Streptozotocin with a dose of 150 mg / kg body weight per day in GD1. While in the control group, only citrate buffer was injected.Cesarean Surgery was done at E11.5 and embryo's heart was extracted from the body.Extraction of RNA, cDNA, and quantitative measurements of the amount of RNA were performed using Real -Time PCR.
Results: Induction of gestational diabetes increased the expersion of desmocollin 2 and col5a2 structural genes in compared to controls, althought only the expersion of desmocollin 2 gene was significant (P<0.05).
Conclusion: We suggest that the induction of DM lead to upregulation of structural genes primarily including desmocollin 2 and col5a2 in embryos heart development.

Background and Objective: Aging reduces cardiac autonomic function parameters such as heart rate response to exercise and heart rate recovery after physical activity. This study aimed to determine the parasympathetic nerves reactivation after upper body exercise among young and middle-aged men.
Methods: In this quasi-experimental study 24 active men based on their age were divided into two groups including 30-35 (young) and 55-60 years old men (middle-aged). Participants performed upper body exercise on a Monark arm ergometer. During the test, heart rate was recorded continuously by electrocardiogram. Also, participants' heart rate was recorded for 10 minutes after completion of the test. In order to measure the time domain parameters of heart rate variability (PNN50 and RMSSD), one-minute successive RR waves intervals collected in 5 minutes and 10 minutes after the completion of the test and then were transmitted to the heart rate variability software for analysis. Also, heart rate recovery was measured in one minute and two minutes after the test by the difference between the maximum heart rate during the test with heart rate in one and two minutes after the completion of the test.
Results: There was a significant difference between PNN50 in minutes 5 and 10 after the test in young men (P<0.05). Young men also had higher values of RMSSD in minutes 5 and 10 compared to middle-aged men. The heart rate recovery in the 2 minutes after test was significantly higher than 1 minute after test in both groups (P<0.05). Heart rate recovery was higher in young people than in middle-aged people at 5 and 10 minutes after high-intensity exercise due to faster withdrawal of sympathetic nerves.
Conclusion: Changes in the autonomic nervous system is dependent on the type, duration of activity, and the age of the participants.

Background and Objective: Considering the role of diet and the use of natural antioxidants in addition to exercise, the attention of researchers has been drawn to take further advantage of the effects of exercise to improve cellular metabolism. Despite the favorable role of exercise and antioxidants on heart health, the simultaneous effect of exercise and consumption of propolis (prepared by bees) is not yet known. This study aimed to investigate the effects of endurance training and propolis against oxidative and myocardial stress in diabetic ovariectomized rats.
Methods: This experimental study was conducted on 36 female Sprague Dawley rats aged 12-16 weeks and weighing 220-250 grams. Six rats were included in the healthy control group. Diabetes was induced in 30 overiectomized rats by intraperitoneal injection of streptozotocin (40 mg/kg). Then, the diabetic animals were divided into five groups of six including diabetic ovariectomized control, sham, propolis, endurance training, and endurance training + propolis. Rats in the training groups trained for eight weeks, five sessions per week, with 55-75% VO2 max. Moreover, propolis was administered 100 mg/kg/day by peritoneal injection. The level of Pro-oxidant-antioxidant balance (PAB) and expression of HSP72 and NF-κB genes were measured.
Results: HSP72 expression was significantly higher in the propolis, endurance training, and endurance training + propolis groups. The levels of NF-kB and malonaldehyde were significantly decreased in the ovariectomized diabetic rats (P<0.05). Expression of HSP72 in the endurance training and endurance training + propolis groups were significantly higher than in the propolis group. Moreover, NF-kB in the endurance training and endurance training + propolis groups were significantly lower than in the propolis group (P<0.05). The value of PAB in the propolis and endurance training + propolis groups were significantly lower than in the ovariectomized diabetic rats (P<0.05).
Conclusion: Exercise and consumption of propolis seem to synergistically improve the protective HSP72 pathway and reduce oxidative stress in heart tissue following estrogen dysfunction and diabetes. However, the interaction of the two depends on endurance training.

Background and Objective: In recent years, studies have been conducted to determine the prevalence rate of congenital abnormalities in different regions of Iran, most of which were conducted on live births. This study was conducted to determine fetal abnormalities in pregnancies leading to legal abortion in Golestan province.
Methods: This descriptive-analytical study was conducted on 199 pregnant women with a gestational age of less than 20 weeks with abortion licenses from the Forensic Medicine Center of Golestan province over 9 months during 2018-19. Demographic characteristics, including parents’ age, ethnicity, and family relationship, and the type of fetal abnormalities were recorded.
Results: Given 29,460 births in Golestan province over a 9-month period, the prevalence of fetal abnormalities was determined to be 6.75 per thousand births. The incidence rates of fetal abnormalities were determined to be 6.78, 6.68, 7.69, and 5.65 per thousand births in native Fars (80 cases), Turkmen (65 cases), Sistani (34 cases), and other (20 cases) ethnic groups, respectively. Since the gender of 80 fetuses was unknown, the incidence rates of abnormality were determined to be 4.36 and 3.72 per thousand births in female (63 cases) and male (56 cases) fetuses, respectively. The most common fetal abnormalities included central nervous system (n=49, 24.62%), chromosomal abnormalities (n=47, 23.61%), and cardiovascular impairments (n=26, 13.06%). The incidence of fetal abnormalities was not found to have a statistically significant relationship with parents' age, ethnicity, and family relationship.
Conclusion: The most prevalent fetal abnormality was related to central nervous system disorders. The incidence of fetal abnormalities had no relationship with the parents’ age, ethnicity, and family relationship.

According to the US Centers for Disease Control and Prevention (CDC) definition, genetic counseling is a process in which information is presented about how genetic conditions affect a patient or his/her family. A genetic counselor collects a patient’s personal and family health history to promote the family’s awareness and perception of specific genetic diseases, testing risks and advantages, disease management, and assessment of available therapeutic options. Intellectual disability (ID) and deafness are two common disabilities with considerable impacts on the quality of life of patients and their families. The present research has investigated the role of genetic counseling in the screening and prevention of deafness and ID based on the studies published in the Web of Science, PubMed, and Google Scholar databases between 2015 and 2023. Genetic counseling can be employed as an influential tool in screening, early diagnosis, and prevention of ID and deafness. Considering that many cases of ID and deafness are rooted in individual genetics, genetic counseling can help lessen the risk factors of developing these disabilities and improve the quality of individual and family life. The effect of genetic counseling, as an influential tool, on screening, early diagnosis, and prevention of ID and hearing loss is also assessed.

Background and Objective: The psychological experience of mental pain can lead to distress similar to that caused by actual injury or trauma. As such, it poses a life-threatening consequence for chronic patients, although it is rarely assessed and treated in clinical settings. One of the diseases associated with high levels of physical and mental pain is the rare disorder neurofibromatosis. This study aimed to evaluate mental pain in patients with neurofibromatosis and its association with disease severity.
Methods: This descriptive-analytical study was conducted on 207 patients with neurofibromatosis who were members of the Iranian Neurofibromatosis Support Association during 2023. Data collection tools included a demographic and clinical information registration form and the Orbach and Mikulincer Mental Pain Scale (OMMP), which comprises 44 items and 6 subscales, with a scoring range from 44 to 220.
Results: The total mental pain score was 121.15±42.41, with a range of 44 to 206. The total mental pain scores for men and women were 123.67±38.98 and 120.31±43.58, respectively. The "confusion" subscale had the highest average score, while the "fear of loneliness" subscale had the lowest average score. There was a statistically significant association between the total mental pain score and its subscales with the severity of the disease and the patient's educational level (P<0.05).
Conclusion: The mental pain scores of patients with neurofibromatosis were evaluated to be relatively unfavorable.

Autism is a neurodevelopmental disorder characterized by deficits in communication skills as one of its most prominent diagnostic criteria, and the initiation of intensive early interventions is a critical determinant in the prognosis of this disorder and the reduction of its severity. This study was conducted to determine the effect of the Parent-Implemented Early Start Denver Model (P-ESDM) interventions in improving communication skills and reducing the severity of symptoms in children with autism. This experimental case report with an A-B design was conducted on 4 children (3 boys and 1 girl) under the age of 60 months diagnosed with autism, who were referred to the Shekoufeha Autism Center in the city of Mahshahr, Iran during 2021. Initially, their parents received training in the P-ESDM interventions through 12 individual, one-hour, weekly sessions. The Autism Treatment Evaluation Checklist (ATEC) was used to assess communication skills, and the Gilliam Autism Rating Scale-Second Edition (GARS-2) was employed to assess autism severity. Assessments were conducted in 7 phases (2 baseline assessments, 3 assessments during the intervention, and 2 follow-up assessments). Data analysis involved descriptive statistics, within-condition and between-condition analyses, and an examination of the percentage of overlapping data (POD) and the percentage of non-overlapping data (PND). The implementation of the P-ESDM training culminated in the decreased mean scores, improved communication challenges, and decreased autism severity scores across all 4 subjects. In the within-condition analysis, the subjects’ communication challenges and autism severity scores exhibited a descending and stable trend. Moreover, in the between-condition analysis, the PND at the baseline and intervention phases was at its maximum (100%), and the POD was at its minimum (0%). The observed changes persisted until the follow-up stage. The findings of this study demonstrated that the implementation of the P-ESDM interventions could significantly reduce communication challenges and the severity of symptoms in children with autism, leading to improvements in their communicative skills.

Background and Objective: Fear of childbirth is a common problem during pregnancy. Previous studies have shown that pregnancy outcomes and experiences can significantly vary across various ethnic groups. This study aimed to determine the prevalence of fear of childbirth among pregnant mothers of various ethnicities referring to comprehensive health service centers in Gorgan, Iran.
Methods: This descriptive-analytical study was conducted on 341 pregnant women of Fars, Turkmen, and Sistani/Baluch ethnicities using a random sampling method at comprehensive health service centers in Gorgan during 2023. Data collection instruments consisted of a demographic and pregnancy characteristics form and the Childbirth Fear Questionnaire (CFQ; Zar and Wijma).
Results: The mean fear of childbirth score in pregnant women was determined to be 69.88±20.19 (severe fear). Among all studied groups, mild fear (21 individuals), moderate fear (100 individuals), severe fear (147 individuals), and clinical fear (73 individuals) were identified in 6.2%, 29.3%, 43.1%, and 21.4% of the pregnant women, respectively. The combined prevalence of severe and clinical fear of childbirth among pregnant women of Sistani/Baluch, Turkmen, and Fars ethnicities was determined to be 73%, 73.3%, and 52.2%, respectively, and this difference was statistically significant (P<0.05). A statistically significant relationship was observed among the variables of age, gestational period, and the level of satisfaction with prenatal care received at comprehensive health service centers (P<0.05).
Conclusion: Severe and clinical fear of childbirth is more prevalent among pregnant women of Sistani/Baluch and Turkmen ethnicities compared to the Fars ethnicity.

Background and Objective: Stroke is considered one of the leading causes of mortality and disability worldwide. Excitotoxicity, neuroinflammation, and oxidative/nitrosative stress resulting from cerebral ischemia/reperfusion lead to cell death, cerebral edema, and cognitive-behavioral impairments, such as deficits in short-term and long-term memory. This study was conducted to determine the effect of minocycline on behavioral-cognitive impairments induced by global cerebral ischemia.
Methods: This experimental study was conducted on 56 male Wistar rats (weighing 220–280 g) at Ferdowsi University of Mashhad, Iran. The animals were randomly assigned to the following groups: Control, solvent, surgery, surgery + solvent + ischemia/reperfusion, surgery + ischemia/reperfusion, and minocycline-treated groups (administered intraperitoneally at doses of 11.25, 22.50, and 45 mg/kg/bw). At specified intervals following the surgical induction of global cerebral ischemia/reperfusion, a surgery procedure and a carotid artery occlusion method were employed for 20 minutes. Following a 30-minute interval post-procedure, the drug or solvent was injected intraperitoneally on day 0. These injections continued for seven consecutive days at a fixed time each day. On day 7, anxiety-like behavior was assessed using the open-field test. Subsequently, the Y-maze test was utilized to evaluate short-term memory, while the Morris water maze (MWM) test was employed to assess spatial long-term memory and reversal memory in the following days.
Results: In the Y-maze test, ischemia culminated in a 33% decrease in short-term memory performance (P<0.05). Minocycline at doses of 22.50 and 45 mg/kg/bw improved short-term memory by 20% and 25% compared to the ischemia group, respectively (P<0.05). In the open-field test, ischemia caused a 66% decrease in time spent in the center of the field, indicating increased anxiety (P<0.05). Minocycline at a dose of 45 mg/kg/bw reduced anxiety by 32% compared to the ischemia group (P<0.05). In the MWM test, ischemia significantly increased the time to find the platform on days 2 and 4 (P<0.05). Minocycline at doses of 22.50 and 45 mg/kg/bw significantly decreased the time to find the platform (P<0.05). In the reversal phase of the MWM test, ischemia led to a decline in long-term memory performance (P<0.05), while minocycline at doses of 11.25, 22.50, and 45 mg/kg/bw significantly improved performance (P<0.05). In the probe trials, ischemia reduced the time spent in the target quadrant by 54% in probe 1 and 47% in probe 2 (P<0.05). Minocycline at 45 mg/kg/bw increased the time spent in the target quadrant by 45% in probe 1 and 34% in probe 2 (P<0.05). No statistically significant changes in motor activity were observed between the groups.
Conclusion: Minocycline, particularly at doses of 22.50 and 45 mg/kg, significantly improves cognitive function, memory, and anxiety without inducing motor activity impairments following cerebral ischemia.
