Abstract

Background: Human dental stem cells have high proliferative potential for self-renewal that is important to the regenerative capacity of the tissue.
Objective: The aim was to isolate human dental pulp stem cells (DPSC), periodontal ligament stem cells (PDLSC) and periapical follicle stem cells (PAFSC) for their potential role in tissue regeneration.
Materials and Methods: In this experimental study, the postnatal stem cells were isolated from dental pulp, preapical follicle and periodontal ligament .The cells were stained for different stem cell markers by immunocytochemistry. To investigate the mesenchymal nature of cells, differentiation potential along osteoblastic and adipogenic lineages and gene expression profile were performed. For proliferation potential assay, Brdu staining and growth curve tests were performed. Finally, all three cell types were compared together regarding their proliferation, differentiation and displaying phenotype.
Results: The isolated cell populations have similar fibroblastic like morphology and expressed all examined cell surface molecule markers. These cells were capable of differentiating into osteocyte with different capability and adipocyte with the same rate. PAFSCs showed more significant proliferation rate than others. Reverse transcriptase PCR (RT-PCR) for nanog, oct4, Alkaline phosphatase (ALP) and glyceraldehydes-3-phosphate dehydrogenease (GADPH) as control gene showed strong positive expression of these genes in all three isolated cell types.
Conclusion: PDLSCs, DPSCs and PAFSCs exist in various tissues of the teeth and can use as a source of mesenchymal stem cells for developing bioengineered organs and also in craniomaxillofacial reconstruction with varying efficiency in differentiation and proliferation.

Abstract

Background: Nanoparticles have wide range of application while there are some reports regarding their probable effects on male reproductive system and spermatozoa.
Objective:  The aim of this study was to evaluate the effect of different doses of silver nanoparticles (AgNPs) (70nm) on acrosome of rat spermatozoa and number of spermatogenic cells.
Materials and Methods:  In this experimental study, in experimental group, 32 male wistar rats (8 rats/group) received oral feeding AgNPs every 12 hr in one spermatogenesis period (48 days) by means of gavages in 25, 50 , 100 and 200 mg/kg concentration (experimental groups 1-4, respectively). The control group (8 rats) was treated on schedule with distilled water. Spermatozoa were stained by triple staining protocol for acrosome reaction. Histological evaluation on testis sections was performed using tissue processing and hematoxylin-eosin (H&E) staining.
Results:  There was significant difference between the control group and the experimental group 1 for acrosome reaction (11.00±0.00 and 24.25±3.68, respectively, p=0.01). There was only significant reduction in spermatogonia cells in experimental group 4. Experimental groups 2, 3 and 4 showed a significant reduction in the number of primary spermatocytes and spermatids as well as spermatozoa. But there were no significant differences between different groups for Sertoli cell number and seminiferous tubule diameter.
Conclusion:  It seems that Ag NPs have acute and significant effects on spermatogenesis and number of spermatogenic cells and also on acrosome reaction in sperm cells. More experimental investigations are necessary to elucidate better conclusion regarding the safety of nanoparticles on male reproduction system.

Abstract

Background: Regarding the close and continuous interaction of infertility staff with hopeless infertile couples and in the contrary the atmosphere of happiness especially in obstetric wards make a sense that considering anxiety and depression it would be a difference between these two wards.
Objective: The objective of this study is the comparison of the rate of depression and anxiety between the two wards of infertility and obstetrics and gynecology.
Materials and Methods: This study is a descriptive-correlation study based on cross-sectional method. 199 individuals who were the staff of infertility and obstetrics and gynecology wards in four provinces enrolled in this study through stratified sampling. Data collection was done by demographic questionnaire, Spiel Berger and Beck depression inventory tests. Data were analyzed by SPSS software using ANOVA test.
Results: The result showed the rate of anxiety in obstetrics and gynecology staff of Isfahan center (54.69±13.58) and depression rate had increased level in infertility staff of Shiraz center (14.94±10.87). Overall, there was significant correlation between anxiety, depression and work place (p=0.047, 0.008 respectively). According to ANOVA test, the mean value of anxiety level was higher in the staff of four obstetrics and gynecology centers and one infertility center
Conclusion: As long as we know that infertile couples have little chance for success rate and obstetrics and gynecology wards patients have little risk of failure in treatment, it could be mentioned that the anxiety and depression in the staff are not correlated with the client illness.

Abstract

Background: Globozoospermia is a severe form of teratozoospermia (incidence < 0.1%) in infertile men that is characterized by round headed sperm and acrosomeless in semen.
Objective: To compare the semen parameters, protamine deficiency, and apoptosis in ejaculated spermatozoa between globozoospermic and normozoospermic men.
Materials and Methods: Thirty six semen samples were divided into two groups including 15 infertile men with total globozoospermic (> 90% round-headed sperm) and 21 healthy donors with normal spermograms as controls. Semen analysis was performed according to World Health Organization criteria (2010). Sperm protamine deficiency was assessed using Chromomycin A3 (CMA3) staining and the rate of apoptotic spermatozoa was evaluated with TUNEL assay.
Results: Sperm concentration, motility, and normal morphology in globozoospermic men were significantly decreased compared with controls (p<0.05). The rate of CMA3-reacted spermatozoa (CMA3+) in globozoospermic men was higher than controls (65.93 ± 11.77 vs. 21.24 ± 7.37, respectively, p<0.0001). The rate of apoptotic spermatozoa (TUNEL positive) were significantly increased in globozoospermic cases with respect to the controls (17.60 ± 10.72 and 5.95 ± 3.02, respectively, p<0.0001). There was no significant correlation between sperm protamine deficiency and apoptosis in globozoospermic men.
Conclusion: Globozoospermic samples contain a higher proportion of spermatozoa with abnormal chromatin packaging and DNA fragmentation than normozoospermic samples. Therefore, in addition to absence of acrosome in the spermatozoa of globozoospermic patients, the high percentage of spermatozoa with immature chromatin and apoptotic marker may be considered as the other etiologies of infertility in these patients.

Abstract

Background: Etiology of more than half of Recurrent Spontaneous Abortion. The etiology of more than 50 percent of Recurrent Spontaneous Abortions (RSA) cases has been remained unexplained. It is supposed that RSA may have "paternal effect" due to supply 50% of embryonic genomic content by male gamete.
Objective: The aim of present study was to evaluate the role of sperm apoptosis and protamine deficiency at same time in RSA cases.
Materials and Methods: Forty fertile (control) and 40 unfertile men with RSA (case) were enrolled in this case-control study. Semen analysis was performed in accordance with WHO criteria and sperm apoptosis and protamine deficiency were evaluated by cell apoptosis detection kit and chromomycin A3, respectively.
Results: Results showed significant different between normal morphology and total motility in two groups. Case group had higher percentage of spermatozoa with protamine deficiency and apoptosis compared to controls significantly.
Conclusion: Our results showed that in cases of RSA, in addition to abnormal sperm parameters, we have a high percentage of spermatozoa with protamine deficiency and apoptosis and these two anomalies may consider as important causes of idiopathic recurrent abortions. It should be advised that sperm chromatin and DNA examinations are useful tools in the process of RSA treatments.

Abstract

Background: Selection of the best embryo for transfer is very important in assistedreproductive technology (ART). Using morphological assessment for this selectiondemonstrated that the correlation between embryo morphology and implantationpotential is relatively weak. On the other hand, aneuploidy is a key genetic factorthat can influence human reproductive success in ART.
Objective: The aim of this lab trial study was to evaluate the incidence ofaneuploidies in five chromosomes in the morphologically high-quality embryosfrom young patients undergoing ART for sex selection.
Materials and Methods: A total of 97 high quality embryos from 23 women at theage of 37or younger years that had previously undergone preimplantation geneticscreening for sex selection were included in this study. After washing, the slides ofblastomeres from embryos of patients were reanalyzed by fluorescence in-situhybridization for chromosomes 13, 18 and 21.
Results: There was a significant rate of aneuploidy determination in the embryosusing preimplantation genetic screening for both sex and three evaluated autosomalchromosomes compared to preimplantation genetic screening for only sexchromosomes (62.9% vs. 24.7%, p=0.000). The most frequent detectedchromosomal aneuploidy was trisomy or monosomy of chromosome 13.
Conclusion: There is considerable numbers of chromosomal abnormalities inembryos generated in vitro which cause in vitro fertilization failure and it seems thatmorphological characterization of embryos is not a suitable method for choosing theembryos without these abnormalities.

Abstract

Background: The study of microRNA expression can be effective in the diagnosing and treating different diseases. miR-135a is one of the most important micro-ribonucleic acids involved in endometriosis. Among the genes that become the target of the miR-135a and are subjected to changes in the endometrium of patients with endometriosis is HOXA10 gene which is expressed in the endometrium in response to steroid hormones.
Objective: The aim of this study was to evaluate the expression of miR-135a and its relationship with the level of HOXA10 gene expression in both endometrial ectopic and eutopic tissues in patients with endometriosis compared to the control samples.
Materials and Methods: In this prospective case-control study, both case-eutopic and case-ectopic tissue samples were obtained from 17 women with endometriosis and the eutopic endometrial tissue was sampled from 17 women with normal endometrium as the control group. The gene's expression of miR-135a and HOXA10 were investigated using quantitative reverse transcription PCR (q-RT PCR).
Results: A significant decrease in the expression of HOXA10 gene was detected in case-eutopic during the luteal phase compared to the control samples (p=0.001), while in the case-ectopic, the expression of this gene was increased (p=0.681) compared to the control samples. In addition, the expression miR-135a in the luteal phase showed a remarkable increase in the case-eutopic endometrial tissue (p=0.026) as well as a significant decrease in the case-ectopic endometrial tissue compared to the control samples (p=0.008).
Conclusion: Considering the inverse relations between the over-expression of miR-135a and the reduction of HOXA10, it seems that miR-135a may be applied as an endometrial diagnostic and therapeutic biomarker.
