Abstract
Background: Birthweight less than 2500 grams is the major indicators of neonatal and infant health. The studies on animals show that copper and zinc deficiency in pregnancy is associated with fetal growth and congenital abnormalities. Therefore, our study was conducted to evaluate the role of these two elements on human embryos.
Materials and Methods: In this descriptive study, cord blood of all infants born in Nik-Nafs Maternity of Rafsanjan was Collected for 1 year. Then, serum was separated and saved. In total, 64 samples including 9 infants with congenital anomalies, 21 infants with a weight equal to or less than 2500 grams and 34 healthy infants were selected randomly as control group. The level of copper and zinc in cord boold was measured by the spectrophotometric method and data analysis was carried out by SPSS 17 software and statistical methods involving Chi-square, T-test and analysis of variance.
Results: No significant relation was shown between the levels of copper and zinc withbirth weight and congenital abnormalities. Also, there was not any significant correlation between these two teo elements and some pregnancy risk factors such as type of delivery, premature rupture of membrane, placental decolman, placental previa, preeclampsia, gravidity, height, head circumference and Apgar scores.
Conclusion: The findings indicate that the levels of copper and zinc in cord blood are not associated with incidence of low birth weight, congenital malformations and pregnancy risk factors.

Abstract
Background and Aim Among the plants with multiple healing properties and a long and common history of use in Iranian traditional medicine, is dog-rose plant with the scientific name of “Rosa canina” that belongs to the Rosaceae family. This study aimed to review the effectiveness of Rosa canina in treatment of different body organs and tissues and emphasizes its therapeutic mechanism.
Methods & Materials This is a review study. About 176 papers published from 2010 to 2018 were extracted from PubMed, Science Direct, Scopus, Google Scholar, Ovid, MagIran, and SID databases using related keywords and entered into study.
Ethical Considerations Ethical issues (including plagiarism, misconduct, data fabrication, falsification, double publication or submission, redundancy) have been completely observed by the authors.
Results Different studies had indicated the importance of Rosa canina as a medicinal plant protecting liver, lowering glucose and lipid levels, and having antioxidant and anti-inflammatory properties. The highest flavonoid activity in the Rosaceae family is related to Rosa canina. The use of herbal extracts in the treatment of common diseases, such as diabetes, fatty liver, urinary tract and Alzheimer's, has been recommended.
Conclusion High qualitative and quantitative diversity of effective ingredients, ease of access, absence of adverse effects of consumption and endemic nature of Rosa canina plant make it necessary to use it for the control and treatment of common human diseases.

Abstract
Background and Aim: This study aimed to compare the microleakage of an adhesive fissure sealant (AFS), a flowable composite resin (FC), and a resin-modified glass ionomer (RMGI) in permanent teeth.
Materials and Methods: This in vitro, experimental study was conducted on 45 extracted posterior teeth with sound fissures. The teeth were randomly divided into 3 groups (n=15). The occlusal fissures were sealed with Beautisealant AFS without etching and bonding in group 1, with Beautifil FC after 37% phosphoric acid etching in group 2, and with Fuji II LC RMGI in group 3. The teeth underwent 500 thermal cycles (5-55°C), and their apices were sealed with wax. They were then immersed in 2% methylene blue for 24 hours. Next, the teeth were sectioned buccolingually and inspected under a stereomicroscope to measure the dye penetration depth as an indicator of microleakage. Data were analyzed by ANOVA, Chi-square test, and Scheffe test (alpha=0.05).
Ethical consideration: The study was approved by the ethics committee of Hamadan University of Medical Sciences (IR.UMSHA.REC.1399.728).
Findings: The microleakage score of RMGI was significantly higher than that of AFS and FC (P<0.05), while the microleakage scores of FC and AFS were not significantly different (P=0.330).
Conclusion: The AFS showed a sealing ability comparable to that of FC, and can be used as an alternative to FC due to its fewer application steps.

Abstract
Introduction: The thickness of the molecular and pyramidal layers in the hippocampus represents a pivotal aspect of Alzheimer's research. This study was conducted to investigate the effect of swimming endurance, resistance, and combined exercises on the molecular and pyramidal layers of the hippocampus tissue thickness of Alzheimer's rats.
Methods: In this experimental study, 40 large white Wistar laboratory rats (6 weeks old; Weight 180-200 g) were randomly and equally divided into five groups: healthy control, Alzheimer's control, endurance, resistance, and combined. Alzheimer's disease was induced by intraperitoneal injection of trimethyltin chloride (8 mg/kg). Two weeks after the injection and confirmation of Alzheimer's induction, the training protocols of endurance (5-sessions/week, the first to the fourth week incrementally from 5-15-min to 45-min of swimming, the fifth to the twelfth week 60-min of swimming), resistance (5-sessions/week, The first week of familiarization with the exercise, week 2; 30%, week3-5; 70-90%, week6-8; 100-110%, week9-10; 120-130%, and week11-12; 140-150% of body weight), combined (2 resistance sessions/week and three endurance sessions/week) was performed for 12 weeks. Forty-eight hours post-intervention, animals were dissected, and hippocampus tissue was harvested. Finally, the data were analyzed at the significance level of P < 0.05.
Results: The thickness of the molecular and pyramidal layers of the hippocampal tissue of Alzheimer's animals decreased compared to healthy animals, and all three endurance, resistance, and combined exercise protocols increased layers (P < 0.001). However, the increase in the molecular and pyramidal layers thickness of the hippocampal tissue of combined group rats compared to the endurance and resistance group had a greater increase (P < 0.01).
Conclusions: These findings highlight the changes in the thickness of the hippocampal tissue layers concerning Alzheimer's pathology and the effect of combined exercises on this parameter. While exercise may have positively affected hippocampal volume and synaptic plasticity, more research is needed to fully understand the impact of exercise on hippocampal layer thickness in Alzheimer's.
