Abstract
Introduction: Abortion has always been a controversial issue and all religions, humanistic and medical communities have opposed it . The complications of illegal abortion are one of the most common reasons of hospital admission in developing countries. W.H.O estimates that the one eight of all pregnancy deaths is due to illegal abortion. Lack of knowledge of the medical team about the abortion regulations and rules can endanger the pregnant mothers life and also create certain problems for medical communities .
Methods: This cross- sectional study was conducted in 2007 and included 110 gynecologists and midwives in Yazd who were studied by census method. Data was collected via self-made questionnaire and data analysis was done by software SPSS program and statistical tests included square K and T test.
Results : Of the total of 110 patients, 16.4% were gynecologists and 83.3% were midwives, 31.8% worked in academic centers and 68.2% were employed at other centers. The awareness level of 25.5% was good. There was a meaningful difference between the awareness level of academic employed and nonacademic employed and also between those who had studied abortion rules regulations.
Conclusion: As 74.5% of the study population had low levels of awareness about the abortion rules, education of midwives & gynecologists about rules & regulations is strongly recommended as it not only helps women's health, but also decreases their legal problems.

Abstract
Introduction: Adipocytokine including chemerin and visfatin have a key role in metabolic regulations, as well as obesity-related disorders such as type 2 diabetes. The aim of this study was to investigate the effect of the 12-week exercise training on changes in levels of visfatin and chemerin in obese women with type 2 diabetes.
Methods: In this study, 30 overweight women with the age range of 45-60 years old were selected and ther were divided into the control group (n = 15), and the experimental group (n = 15) which had no significant differences based on the body fat percentage and the body mass index. Exercise program consisted of increasing aerobic exercise three times were for 12 weeks. To measure Chemerin and Visfatin, blood samples before and 24 hours after the last training session were collected. Data evaluation was performed using ANCOVA to compare the pre-test and post-test in each group.
Results: According to the obtained results, there was no significant difference between weight, body mass index, lean body weight, fat mass and fat percentage, but the chemerin levels have been increased significantly (p=0.0001) and also visfatin and glucose levels have been decreased (respectively p=0.0001 and p=0.001).
Conclusion: Aerobic activities are a stimulating factor for increasing in the chemerin hormone and also a stimulating factor for decreasing in the Visfatin hormone. It could be said that regular aerobic activities in 12 weeks are a good stimulating factor for creating changes in these hormones in women with diabetes and it is probably one of the contributing factors of physiologic changes resulted from these exercise activities is changes in these hormones.

Abstract
Introdution: Muscle weakness that is caused by cancer called Cachexia. One of the causes of the formation of the cachexia is the change in protein degradation, and the ubiquitous protease and Autophagy Lysosomes system is the most important protein breakdown system. Resistance training has been one the best stimulator of increasing muscular mass. Therefore, the purpose of this study was to investigate the effect of a period of resistance training on the muscle protease activity and autophagy flux in mice with cancer induce cachexia.
Methods: This study was conducted on 12 male BALB / c mice (age 6 weeks) and CT-26 tumor implanted into them. Then they were divided into two groups of resistance training (n=6) and control (n=6). Training group performed 6 weeks progressive resistance training. The protease activity was evaluated by fluorogenic substrate method and LC3B and p62 evaluated by western blot method. Independent t-test was carried out at P<0.05 for statistical analysis using Prism (7) software.
Results: There was no significant difference in Proteasome activity (p=0.13), muscle weight (p=0.24), and CT26 tumor volume (p≥0.05) between two groups of resistance training and control, but p62 decreased in the resistance training group (p=0.032).
Conclusion: However, the autophagy flux has improved in the part of cargo breakdown with resistance training, but perhaps the presence of a tumor inhibits muscle response to resistance training or this type of resistance training is not an appropriate intervention for treating cachectic muscle. To treat cachexia through the resistance training, either this method would be combined with other interventions or other methods of the resistance training can be applied.

Abstract
Introduction: With the development of hydrogels from half a century ago, their application in various medical fields, including drug delivery has been widely expanded. Hydrogels used in this field are produced with synthetic polymers such as polyvinylpyrrolidone, polyvinyl alcohol, or natural polymers like chitosan, agarose, and hyaluronic acid to develop biocompatible, biodegradable, and non-immunogenic drug carriers. However, limitations such as inadequate response to stimulation, low homogeneity, and poor loading capacity for hydrophobic drugs have limited the use of hydrogels for drug delivery due to the hydrophilic nature of the hydrogel. The use of nanoparticles in the structure of hydrogels to produce hydrogel nanocomposites leads to more diverse interactions such as hydrogen and electrostatic bonds in addition to covalent interactions between hydrogel polymers. In addition to enhancing the mechanical properties of the hydrogel and further homogeneity, these interactions lead to the formation of platforms responsive to various stimuli, attaining sustained release, and ameliorating the poor loading of hydrophobic drugs used in cancer treatment and wound dressing.
Conclusion: A review of a research conducted in the last 20 years represents that the application of nanocomposite hydrogels in drug delivery includes a wide range of production methods, nanoparticles to create various stimulation mechanisms, and therapeutic applications. Indeed, research has been focused on developing smart systems for controlled release with stimuli to reduce side effects of conventional cancer treatment methods, such as chemotherapy, by targeting drug delivery and reducing drug administration frequency and mitigating chronic wound complications by the release of growth factors.

Abstract
Introduction: Multiple Sclerosis is a chronic, inflammatory disorder of the central nervous system, which leads to demyelination of nerves. Treatment with interferon beta is one of the best approaches to reduce recurrence and progression of the disease. The aim of this study is to search for the relationship between 4 polymorphisms FokIrs10735810, TaqIrs731236, ApaIrs797532 and BsmIrs1544410 located in the vitamin D receptor in MS patients responsive and non-responsive to interferon beta treatment and pave the way for the correct and fast administration of the appropriate drug, as well as reducing time, cost and lack of success in treatment.
Methods: The type of study is observational and the study method is case-control. Blood samples were taken from 200 MS patients who were treated with interferon (100 responders and 100 non-responders). Using PCR-RFLP technique, the samples were subjected to enzymatic digestion with restriction enzymes ApaI, FokI, TaqI and BsmI. The data were evaluated using SPSS version 16, SNP Analyzer and Prism software, and K-tests and logistic regression.
Results: A significant difference in the genotypic and allelic frequencies of ApaI (p=0.68), BsmI (p=0.65), FokI (p=0.57) and TaqI (p=0.50) polymorphisms in the patients between the two responsive and non-responsive groups to treatment was not observed.
Conclusion According to our findings, there was no significant correlation between ApaI, FokI, TaqI and BsmI polymorphisms located in vitamin D receptor gene and response to treatment.
