Abstract

Background: Fetal DNA in maternal plasma and serum has been shown to be a useful material for prenatal fetal sex determination during early gestational ages. Non-invasive prenatal diagnosis is now possible at 8th week of pregnancy, by maternal blood sample testing.
Objective: The purpose of this study was to evaluate two DNA extraction methods from mother plasma and its routine clinical application in bovine fetus gender determination with non-invasive method.
Materials and Methods: Maternal blood samples were taken from 40 pregnant cows during the 8th-38th weeks of gestation. DNA was extracted from 350 μl of maternal plasma with two salting-out and phenol-chloroform methods. The absorption in A260 and purity (A260/A280) of extracted DNA were detected by ultraviolet spectrophotometer. Three μl of the extracted DNA with phenol-chloroform method was used as a template. The PCR reaction was carried out to amplify the fragments of X and Y chromosomes of amelogenin, TSPY and BC1.2 genes.
Results: The difference between the mean absorption of DNA extracted by phenol-chloroform method and salting-out method was not significant in A260 (p>0.05, p=0.3549), but the difference between mean purity (A260/A280) of DNA extracted by phenol-chloroform method and salting-out method was significant (p<0.001). X chromosome fragment was detected in all 40 samples and Y chromosome fragments were detected in 25 plasma samples which were delivered a male calf. The sensitivity and specificity of test was 100% with no false negative and false positive results.
Conclusion: The results showed that phenol-chloroform method is a simple and sensitive method for isolation of fetal DNA in maternal plasma.

Abstract

Background: The human female reproductive tract (FRT) is constantly deal with the invading pathogens. Recognition of these pathogens is attributed to the family of Toll like receptors (TLR) as a major part of the innate immune system. We and others have previously revealed that TLRs1-6 express in the female reproductive tract. However, more studies should be done to detect TLRs 7-10 in the female reproductive tract, especially in the fallopian tubes.
Objective: To examine the expression of TLRs7-10 in human fallopian tube tissue.
Materials and Methods: Using immunostaining techniques, distribution of TLR7-10 was studied in surgical sections from the uterine tubes, obtained from patients undergoing tubal ligation and hysterectomy for benign gynecological conditions. RT-PCR was used to show the existence of TLR7-10 genes in fallopian tube tissue.
Results: TLR7-10 proteins were detected in the fallopian tube epithelium, although the intensity of staining was not equal in cases. TLR7-10 genes were expressed in human fallopian tube tissue.
Conclusion: This study indicates that TLR7-10 is expressed in fallopian tubes tissues, and may play an important role in microbial recognition, and in host defense against ascending infection.

Abstract

Background: In recent years, a growing number of interventions for treatment of female orgasmic problems (FODs) have emerged. Whereas orgasm is a extra biologically and learnable experience, there is a need for practitioners that to be able to select which therapy is the most appropriate to their context.
Objective: In this critical literature review, we aimed to assess areas of controversy in the existing therapeutic interventions in FOD with taking into accounted the Iranian cultural models.
Materials and Methods: For the present study, we conducted an extensive search of electronic databases using a comprehensive search strategy from 1970 till 2014. This strategy was using Google Scholar search, “pearl-growing” techniques and by hand-searching key guidelines, to identify distinct interventions to women's orgasmic problem therapy. We utilized various key combinations of words such as:" orgasm" OR "orgasmic "," female orgasmic dysfunction" OR Female anorgasmia OR Female Orgasmic Disorder ", orgasmic dysfunction AND treatment, “orgasm AND intervention”. Selection criteria in order to be included in this review, studies were required to: 1 employ clinical-based interventions, 2 focus on FOD.
Results: The majority of interventions (90%) related to non-pharmacological and other were about pharmacological interventions. Self-direct masturbation is suggested as the most privilege treatment in FOD. Reviewing all therapies indicates couple therapy, sexual skill training and sex therapy seem to be more appropriate to be applied in Iranian clinical settings.
Conclusion: Since many therapeutic interventions are introduced to inform sexually-related practices, it is important to select an intervention that will be culturally appropriate and sensitive to norms and values. Professionals working in the fields of health and sexuality need to be sensitive and apply culturally appropriate therapies for Iranian population. We further suggest community well defined protocols to screen, assessment and management of women’ sexual problems such as FOD in the Iranian settings.

Abstract

Background: KLC3 protein as a member of the kinesin light-chain protein family plays an important role in spermatogenesis, during formation of mitochondrial sheath in the mid piece of the sperm tail.
Objective: This study for the first time aims to compare the expression of the KLC3 gene between fertile and infertile individuals.
Materials and Methods: Semen samples were collected from 19 fertile individuals who were selected from embryo-donor volunteers and 57 infertile individuals who had abnormal sperm parameters according to world health organization criteria. Sperm parameters using computer assisted sperm analysis and the quantitative KLC3-gene expression using the real-time PCR method were measured.
Results: Our results revealed a significant correlations between sperm concentration with relative expression of KLC3 only in infertile groups (r=0.45, p=0.00). A significant correlation was not found between KLC3 expression and sperm motility; however, the relative expression of KLC3 was significantly higher in asthenozoospermic compared to non-asthenozoospermic individuals.
Conclusion: Low expression of KLC3 may result in improper function of midpiece, which has important function in sperm motility. The results of this study show that aberrant expression of KLC3 might be associated with phenomena like oligozoospermia and asthenozoospermia. This article is extracted from student’s thesis.

Abstract

Background: Diabetes has an adverse effect on spermatogenesis by rising oxidative stress.
Objective: The aim of this study was to investigate the effect of Teucrium Polium extract administration on spermatogenesis and testicular structure in diabetic rats induced with Streptozotocin.
Materials and Methods: 32 male Wistar rats were randomly divided into four groups (n=8/each): control group, diabetic group received distilled water, and two experimental groups included diabetic rats treated with 50 and 100 mg/body weigh of Teucrium Polium extract for 6 six weeks. After six weeks, the left testis had been removed and the morphometrical study was performed. Blood samples were collected from the ophthalmic veins of the rats and plasma levels of glucose and testosterone hormone were measured afterward.
Results: The reduction in diameters of the seminiferous tubules and thickening ofthe wall of the seminiferous tubules (p=0.05) were seen in diabetic rats. Also, thedegenerative changes in cells arrangement have been observed. Statistical analysisshowed the use of Teucrium Polium significantly improved the above disorders intreatment group (100 mg/BW) in contrast to the non treated diabetic group (p=0.05),but no significant difference was seen between the experimental group treated with50 mg/BW of Teucrium polium and diabetic group (p=0.08). These data alsorevealed that treatment of diabetic rats with 100 mg/BW of Teucrium Polium extractsignificantly improves the change in serum glucose (p=0.001) and testosterone(p=0.03).
Conclusion: The results of the present study indicate that diabetes produces degenerative changes in the testis of rats and administration of Teucrium polium reduces complications resulted from diabetes.

Abstract

Background: Oocyte developmental competence is one of the key factors for determining the success rate of assisted reproductive technique.
Objective: The aim of the current study was to investigate the effect of L-carnitine (LC) supplementation during in vitro maturation (IVM), on preimplantation embryo development and expression of genes involved in embryo competence derived from oocytes selected with brilliant cresyl blue (BCB) test.
Materials and Methods: Cumulus-oocyte complexes (COCs) were obtained from NMRI mice ovaries. COCs were stained with BCB and then BCB+ (colored cytoplasm) oocytes cultured in IVM medium supplemented with 0.3 or 0.6 mg/ml LC. COCs untreated with LC were used as control. Fertilization rate and blastocyst development rate were determined after in vitro fertilization. In addition, quantitative reverse transcriptase polymerase chain reaction was used to measure relative genes expression related with development (Ccnb1, Mos, Ces5, and Dppa2) and apoptosis (Bax and Bcl-xL) in oocytes and embryos.
Results: Oocytes treated with both LC concentrations showed higher blastocyst development rate compared with untreated oocytes (p<0.01). Moreover, fertilization rate was increased in oocytes treated with 0.6 mg/ml LC (p<0.01). Treatment of oocytes with both LC concentrations increased (p<0.01) the level of Ccnb1 mRNA in MII oocytes. The two-cell stage embryos and blastocysts derived from LC-treated oocytes (0.6 mg/ml) showed increased the expression levels of Dppa2 and Bcl-xl mRNA, respectively (p<0.01).
Conclusion: The results of the present study show that adding of LC to the IVM medium of BCB+ oocytes can ameliorate reproductive success following in vitro fertilization.

Abstract

Background: The effect of antioxidant therapy on sperm DNA fragmentation index (DFI) and achieving natural pregnancy were under debate. Very few studies have showed the rate of pregnancy rate after the antioxidant therapy due to ethical and technical limitations.
Objective: The aim of this cohort study was to determine the improvement rate of sperm DFI and natural pregnancy rate after the antioxidant therapy in infertile men.
Materials and Methods: 1645 infertile men were subjected for this study from May 2015 to December 2017. The Spermogram and sperm DFI were assessed using World Health Organization (WHO) 2010-based protocols and sperm chromatin structure assay (SCSA), respectively, in sperm samples before and after antioxidant therapy.
Results: The total sperm DFI improvement rate was 38.9% in the total population. Sperm DFI improvement had close correlation with total motility (r= 0.731, p= 0.001) and progressive motility improvement (r= 0.885, p= 0.001); 16.8% of individuals who completed antioxidant therapy for nine months achieved natural pregnancy.
Conclusion: The results of the current study suggested that SCSA along with spermogram might be a suitable option for the evaluation of fertility potential. In addition, antioxidant therapy may be useful for men with high levels of sperm DFI. However, the rate of pregnancy was still low and other treatment protocols such as assisted reproductive technology may be necessary.

Abstract

Background: The expression of miR-302 over the period of early embryogenesis could possibly regulate the maternal transcript clearance. Zygotic transcription activation is mostly related to maternal messages degradation.
Objective: In this study, the effects of in-vitro maturation technique (IVM) on the expression of miR-302 in human embryo produced from immature and mature human oocytes (matured in vitro and in vivo, before sperm exposure) obtained from females under gonadotrophin therapy were evaluated for assisted reproduction.
Materials and Methods: Immature oocytes were cultured in vitro. The injection of oocytes-producing polar bodies was given using fresh sperm. Then, the embryo quality score was assessed in the IVM group compared with the control group. In both the groups, embryos with normal morphology were included in the molecular study. Only one blastomere was removed from three-day embryos and then the embryos were frozen. The expression of miR-302 in embryos was measured through quantitative realtime polymerase chain reaction.
Results: Our data showed a significant reduction of miR-302 expression in the IVM group vs. the control group (p = 0.02). The embryo quality score showed a significant difference between the two groups (p = 0.01).
Conclusion: The present study demonstrated that the IVM process had a negative effect on the expression level of miR-302 in human pre-implantation embryos. Considering the major role of expression miR-302, a decrease in miR-302 expression
could be related to a reduced potential  in the early embryonic development.
