Tasks have been given an ever-increasing attention on the part of researchers in the recent decades, particularly in relation to second language acquisition research. A highly influential factor in task performance, motivation, seems to have been neglected by educational researchers, and this negligence toward the role of motivation gets more prominence while considering the part played by motivational changes during task-supported instruction. Informed by this alleged gap in studies on the role of motivation on task performance, the researchers in the current study strived to probe the dynamic character of foreign language motivation during task-supported language instruction both within single lessons and sequences of lessons over a period of six weeks. Having chosen a sample of 7 young adults, the researchers gathered the data by means of: (1) detailed lesson plans, (2) interviews with selected participants conducted after each session during the study, and (3) Motometers filled out at five-minute intervals during a single class to gain information on motivational changes. The quantitative and qualitative analysis of data revealed that language learning motivation changed not only during a single lesson but also from one lesson to the next. Factors responsible for such changes were found to be related to task features, task implementation, and individual differences. The implications of findings are discussed throughout the paper.

The present study was conducted to examine the existence of any possible relationship between willingness to communicate (WTC) and multiple intelligences (MI) among over 500 EFL learners. The study also investigated the effect of gender on the relationship between these two constructs. The data for the research were gathered using a three-part questionnaire which was presented in the students' native language. A revised version of Gardner's MI measure was used to assess the participants' intelligences. Students' WTC was measured through a twenty-item WTC scale. In addition, a biodata questionnaire was used to get some demographic information about the learners. The findings revealed that the MI profile of learners of English has a significant correlation with their willingness to participate in L2 communication and that the link between MI and WTC is affected by gender.

This study was carried out to find out if there was any significant difference in learning English collocations by learning with different dominant experiential learning styles. Seventy-five participants took part in the study in which they were taught a series of English collocations. The entry knowledge of the participants with regard to collocations items of the treatment as well as the difficulty level of the items were controlled. Upon the completion of the treatment, participants' retention of the items was measured in an immediate and a delayed recognition type tests. The results showed a statistically significant difference among the four experiential learning style groups. The findings offer a number of implications with regard to the teaching and learning of English collocations.

Background: Evidences suggest an association between the prevalence of thyroid peroxidase (anti-TPO) and anti thyroglobulin (anti-Tg) with recurrent abortions and infertility. Iodine deficiency was once endemic in Iran and little data is available about the prevalence of these antibodies in different groups of fertile or infertile individuals. Objective: This case control study was designed to compare the presence of anti-TPO and anti-Tg in four groups of women to reveal their role in the etiology of recurrent abortion and infertility. Materials and Methods: Four groups of euthyroid women referring to Avicenna Infertility Clinic in Tehran were selected; 95 cases as fertile controls and 70, 78 and 137 cases with male and female factor infertility and recurrent abortion respectively. TSH, anti-TPO and anti-Tg were evaluated by chemiluminescent immunoassay. Results: The prevalence of the above mentioned autoantibodies in euthyroid controls was about 25% and the percentage of people with an anti-Tg >500 was two times bigger in the abortion group compared to the control group (p<0.05) and the proportion of people with an anti-Tg >500 in younger cases in the abortion group was significantly higher than the rest of the cases (p<0.05). Anti-TPO distribution had no significant differences. Conclusion: There were no statistically significant differences among four groups. It seems that more comprehensive studies are needed to reach a common conclusion about thyroid autoantibodies in women with recurrent abortions in different groups and different parts of Iran. In addition, dividing the recurrent abortion and infertility groups on the basis of their etiologies could be effective. [ABSTRACT FROM AUTHOR]

Background: Endometrium undergoes several changes in structure and cellular composition during pregnancy. Granulocyte Colony-stimulating Factor (GCS-F) is an important cytokine with critical role in embryo implantation and pregnancy. The aim of the present study was to evaluate the impact of intrauterine injection of G-CSF in patients who suffer from unexplained recurrent miscarriage (RM). Methods: In the present randomized clinical trial, a total of 68 patients were randomly allocated into two study groups including intrauterine G-CSF (n=23, 300 μg) injection and control group (n=27, no G-CSF injection). Eighteen out of 68 patients were excluded from the final analysis due to different reasons. All patients were in Ovulation Induction (I/O) cycle. In G-CSF group, intrauterine injection of G-CSF was done twice in the cycle. All enrolled patients were under 40 years old and had at least two unexplained pregnancy losses. Pregnancy was evaluated by titer of βhCG, presence of gestational sac (implantation) and fetal heart rate (clinical pregnancy) was assessed by vaginal ultrasonography. Student's T test and Mann-Whitney U were used for analysis. The p≤0.05 was determined as statistically significant. Results: No significant differences were observed between the two study groups when the rates of chemical pregnancy (26.1% vs. 29.6%, p=0.781), implantation (26.1% vs. 22.2%, p=0.750), clinical pregnancy (17.4% vs. 11.1%, p=0.689) and abortion (33% vs. 37.5%, p=0.296) were compared. Conclusion: In our study, no significant difference was observed between the two study groups when the rates of chemical pregnancy, implantation, clinical pregnancy and abortion were compared.

Background: GnRH agonist administration in the luteal phase has been suggested to beneficially affect the outcome of intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) cycles. This blind randomized controlled study evaluates the effect of GnRH (Gonadotropine Releasing Hormone) agonist administration on ICSI outcome in GnRH antagonist ovarian stimulation protocol in women with 2 or more previous IVF/ICSI-ET failures. Methods: One hundred IVF failure women who underwent ICSI cycles and stimulated with GnRH antagonist ovarian stimulation protocol, were included in the study. Women were randomly assigned to intervention (received a single dose injection of GnRH agonist (0.1 mg of Decapeptil) subcutaneously 6 days after oocyte retrieval) and control (did not receive GnRH agonist) groups. Implantation and clinical pregnancy rates were the primary outcome measures. Results: Although the age of women, the number of embryos transferred in the current cycle and the quality of the transferred embryos were similar in the two groups, there was a significantly higher rate of implantation (Mann Whitney test, p=0.041) and pregnancy (32.6% vs. 12.5%, p=0.030, OR=3.3, 95%CI, 1.08 to 10.4) in the intervention group. Conclusion: Our results suggested that, in addition to routine luteal phase support using progesterone, administration of 0.1 mg of Decapeptil 6 days after oocyte retrieval in women with previous history of 2 or more IVF/ICSI failures led to a significant improvement in implantation and pregnancy rates after ICSI following ovarian stimulation with GnRH antagonist protocol [ABSTRACT FROM AUTHOR]

Objective: Repeated implantation failure (RIF) is a major challenge in reproductive medicine. On the other hand, there has not yet been established a confirmed outcome regarding the usage of platelet-rich plasma (PRP) in women undergoing intracytoplasmic injection (ICSI) or in-vitro fertilization (IVF); hence, the objective of this study was to evaluate the effect of the intrauterine infusion of PRP on pregnancy outcomes in women undergoing ICSI., Methods: In this prospective double-blind clinical trial, 100 women with at least two previous unexplained RIF, who were candidates for frozen-thawed embryo transfer, were allocated into two groups. One subgroup of patients was treated by intrauterine infusion of PRP (0.5CC, contained platelet 4-5 times more than a peripheral blood sample, which was performed 48 hours before blastocyst transfer) and the other subgroup was treated by intrauterine catheterization only. We compared the implantation rates between the two groups., Results: The pregnancy rate was 20% in the intervention subgroup, while in the control subgroup it was 13.33%; therefore, there was a significant statistical difference between the two groups., Conclusions: According to this paper, PRP could be successful in improving the pregnancy outcome in RIF patients, and we highly recommend other studies with larger samples to confirm the PRP therapy efficacy in RIF patients.
