The aim of this study is group education based on acceptance and commitment (ACT) on positive emotions towards the spouse in women who have undergone emotional divorce. The research method was quasi-experimental: pretest-posttest and two-month follow-up. The statistical population included married women in the situation of emotional divorce who consulted with Yazd Family Counseling Center in 2020. All women who used the services of this center completed an emotional divorce questionnaire. Individuals undergoing emotional divorce were randomly assigned to experimental and control groups (20 people in each group). Both groups completed a questionnaire of positive emotions towards their spouse and the experimental group was exposed to eight 90-minute weekly sessions based on acceptance and commitment training. In the end, the questionnaire was administered again in both groups and in the follow-up period after 8 weeks, and both groups completed the questionnaires. The results of analysis of covariance showed that teaching an approach based on acceptance and commitment improves positive emotions towards the spouse in married women suffering from emotional divorce. Thus, ACT skills lead to cognitive evaluation of emotions, decrease in negative emotions, increase in positive emotions and adaptive behavior, and ultimately lead to increased cognitive regulation of emotions.

During evolution, various compounds against herbivors were developed in plant species. Disturbance in digestive system by plant enzyme inhibitors is one of the effective methods in integrated pest managment programs. In this study, the effects of total Goebelia alopecuroides and Vicia ervilia seed extracts and their fractions were assessed against proteolytic activity of cotton bollworm. Total extracts of G. alopecuroides was effectively inhibited digestive proteinase of cotton bollworm compared with that of V. ervilia. The inhibitory effect of G. alopecuroides on Bovine trypsin and chymotrypsin as well as insects’ trypsin and chymotrypsin was higher than that of V. ervilia. Total seed extracts of V. ervilia significantly decreased digestive chymotrypsin activity. Ammonium sulfate precipitation of seed extract also showed significant inhibitory effect among the fractions. The fifth fraction of G. alopecuroides showed the highest inhibititory efect agianst digestive proteolytic activity of cotton bollworm and bovine trypsin. The first fraction of V. ervilia significantly inhibited total proteolytic activity.The first fraction of both plants seed extracts inhibited digestive trypsin of cotton bollworm compared to the other fractions. The third fraction of V. ervilia and the forth fraction of G. alopecuroides showed higher inhibitory effect on digestive chymotrypsin of cotton bollworm comperd with the other fractions. Comparing crude extracts effects of both plant species on laboratory and wild populations of cotton bollworm showed that wild ones was susseptible compared with the laboratory population.

The present study tended to review the current situation of the international relations management filed in terms of using foreign scholars and experts and holding continues training courses for foreign students at the Tabriz University of Medical sciences during the Years 2005-2010. In this descriptive study، two checklists were designed and used for obtaining the data. Of the two check lists، one was used for situation analysis of the inviting foreign scholars and experts and the other was taken into account for analysis of holding short-term training courses for foreign students through literature review and the panel meetings of the experts and there were also a total of 65 questions. Census sampling method was used to evaluate the foreign scholars and holding training courses for foreign students. Then، the results showed that Tabriz University of Medical Sciences has performed poorly in inviting foreign scholars and experts. Therefore، none of these regulations، prioritization، planning، evaluation، survey، and feedback was considered even at the minimum level. Further، in terms of holding short-term training courses for foreign students were reviewed; none of the desired statements was met in short-term training courses neither.

Bacillus subtilis is considered as a suitable host for gene cloning and protein expression due to non-pathogenicity and ability to secrete high amounts of proteins. However, transformation efficiency of ligated plasmid DNA into competent cells of B. subtilis is low, as compared to that into CaCl2 shocked cells of Escherichia coli. Therefore, cloning the target in E. coli using a shuttle vector before transfer into B. subtilis by a high amount of hybrid vector is more efficient. The aim of this study is construction a shuttle vector using pW980 and pET-16b plasmids for gene cloning and expression in B. subtilis. pWB980 plasmid was isolated from its host using alkaline lysis method. It was undergone a double digestion to obtain the segment of interest using EcoRI  and SnaBI enzymes. Then a special fragment of pET-16b plasmid was also amplified by PCR and was double digested. Ligation reaction was performed between these two segments and then it was transferred to E. coli TOP10. Following screening the cells containing shuttle vector, plasmid was extracted and was transferred to B. subtilis WB600 by an effective method. The resulting shuttle vector replicated easily in both hosts. It showed good stability in B. subtilis, which is helpful for its maintenance in its host. In this study, the resulting shuttle vector - pMR12 - had 8 unique cloning site in its polylinker and a suitable size (5.4 kb), which make it possible to simply gene cloning into it. This is the first report of construction of an expression shuttle vector for Escherichia coli and Bacillus subtilis in Iran.

Backgrounds and Recently، the activity of paraoxonase-3 enzyme has been reported in follicular fluid، where the concentration of this enzyme in follicular fluid is three times higher than serum. However، the rule of this enzyme in the ovarian function is yet unknown. In the present study، the activity of this enzyme and the ratio of antioxidant/peroxidation activity within the follicular fluid of infertile and fertile who underwent reproductive cycles stimulatory will be evaluated and compared and their variation are correspond with to the oocyte number. The follicular fluid obtained from 50 infertile couples who underwent assisted reproductive techniques، follicular fluid paraoxonase-3 enzyme activity was determined by High Performance Liquid Chromatography، high-density lipoprotein was measured by sedimentary، total antioxidant capacity was by ELISA method and levels of malondialdehyde by tiobarbituric acid assay. From 50 women that present in this study، 20 women were infertile and 30 subjects were fertile. The paraoxnase-3 activity rate in follicular fluid of infertile women were significantly lower in compared with fertile women (p<0. 05). The average ratio of paraoxonase-3/ malondialdehyde in follicular fluid of infertile women were obtained lower than fertiles. Malondialdehyde concentration in follicular fluid of infertile women were significantly high (p<0. 05). The level of high-density lipoprotein and total antioxidant capacity in follicular fluid were not significantly. The result of present study showed that paraoxonase-3 activity and paraoxonase-3/ malondialdehyde rato in follicular fluid of infertile women are lower and while malondialdehyde levels conversly was higher.

Obesity، a serious risk factor for chronic diseases، especially among women، is an important worldwide public health problem. The aim of this study was to evaluate the effects of L-carnitine supplementation with or without moderate aerobic training on serum lipid profiles and body fat percentage in obese women. In this clinical trial، 44 obese women were randomly assigned to 4 groups (n=11 each) as follows: 1: L-carnitine supplementation (2 g/day)، 2: aerobic training+placebo group، 3: L-carnitine supplementation + aerobic training and 4: placebo. All interventions had an 8 week period and subjects of aerobic training groups underwent 8-week aerobic training protocol (3 sessions a week [24 sessions]). Body mass index، body fat percentage، daily dietary intake and serum fasting free L-carnitine، total cholesterol، triglycerides، LDL and HDL cholesterol levels of each subjects were measured before and after interventions. Analysis of covariance was used for comparing of variables means between groups. Body fat percentage decreased significantly in the aerobic training+placebo and in L-carnitine supplementation+aerobic training groups. In the L-carnitine supplementation group، aerobic training+pl­acebo and the L-carnitine supplementation+aerobic training groups، significant reductions were observed in serum total cholesterol and triglyceride levels. LDL-C levels decreased significantly in the L-carnitine+aerobic training group. Results indicated beneficial effects of L-carnitine supplementation alone or combined with aerobic training on serum lipid profiles and effects of aerobic training in lowering of body fat percentage in obese women. L-carnitine supplementation and aerobic training may be effective in delaying onset of chronic diseases in obese subjects.
