Background and Objective: Non-specific granulomatous prostatitis is an uncommon diffuse inflammatory condition of the prostate. It is important because it may be mistaken for prostatic carcinoma. The aim of the study was to determine the prevalence of non-specific granulomatous prostatitis (NSGP) and comparing the results of transrectal ultrasonography, serum prostate specific antigen (PSA) and free prostate specific antigen levels, digital rectal exam (DRE) in NSGP with the prostate carcinoma and benign prostate hyperplasia.Materials and Methods: During a cross-sectional study, the prostate needle biopsy cases with the granulomatosts prostatitis diagnosis that had been referred to one of the largest pathology centers (1 year: 2006) were found and their clinical files were revised from the point of DRE, transrectal ultrasonography (TRUS), fPSA, and PSA. Some clinical and pathology findings such as age, microscopic findings, sonography information and experimental findings that had been necessary for the study were gathered and analyzed using SPSS software.Results: Out of 783 needle biopsies of prostate, 8 (1.02%) cases were non-specific granulomatous prostatitis. The age range of patients was 55-76 years (with a mean of 66.1 years). Mean of PSA level was 19.45 ng/ml and fPSA level was 0.7 ng/ml. In 2 patients, TRUS showed focal hypoechoic areas and in other 2 of these DRE revealed asymmetry and mild nodularity.Conclusion: There is no pattern of clinical, biochemical or ultrasound findings that allows a specific diagnosis of granulomatous prostatitis to be made or differentiate it from prostatic carcinoma and the biopsy is still necessary for the certain disease diagnosis.

چکیده: 

Background: MicroRNAs are endogenous non-coding RNAs with important regulatory and cell fate functions. Many studies have shown that several microRNAs are obviously up-regulated during stem cell DIFFERENTIATION. The question rises here is weather inhibiting DIFFERENTIATION will affect the stemness and self renewal status of stem cells.Methods: miRCURY ™LNA microRNA inhibitor (anti-miR-145 and anti-let7g) are a sequence-specific and chemically modified oligonucleotide that specifically target and knockdown miR-145 and let7g miRNA molecules. Unrestricted somatic stem cells (USSCs) were isolated from umbilical cord blood and treated with LNAs. The effect of anti-miRNA transfection was assessed by quantitative real-time PCR.Results: Real-time PCR showed that LNA was efficiently introduced into the cells and reduced miR145 and Let7g expression levels to 40% and 10% in relation to corresponding scramble control, respectively. Gene expression analysis as to self renewal and expansion showed more than 3.5 fold up regulation in Oct4 in cells treated with mir145 inhibition. Similarly a significant up to 2.5 fold up-regulation in Oct4 and cMyc expression was observed in samples treated with anti-let7g.Conclusion: Suppression in DIFFERENTIATION inducing microRNAs (miR-145 and let7g) can enhance the self renewal and stemness status of USSCs at transcriptional level.

چکیده: 

Objective: In human, early oocyte DIFFERENTIATION occurs during fetal life. But in mice, it takes place in early postnatal period, providing a valuable model for investigating the effect of different factors on oocyte DIFFERENTIATION. It is thought that estrogen may have a role on early oocyte development and therefore the aim of the present study is to evaluate the effect of tamoxifen on early oocyte DIFFERENTIATION and follicular development in mice.Materials and Methods: In this study 30 adult female and 15 adult male mice are used. Two female mice at their sterous cycle were housed in a cage for mating. Observation of vaginal plaque was considered as the first day of pregnancy and the mice on the 13th day of pregnancy received 100 micro gram tamoxifen as ip injection. After delivery, the 2, 3, 6 and 7 days old pups were sacrificed and their ovaries removed and fixed and prepared for light and electron microscopy. Ultrastructural morphology of differentiating oocytes was studied and the number of oocyte nests and diameter of primordial and primary follicles were determined.Results: Microscopy showed that oocyte nests were formed on 2-3 day old pups and follicles were distinguished on 6 and 7 days. Morphometric studies revealed that the number and diameter of oocyte nests were significantly reduced in experimental group, in comparison to control group (p<0.001). However, the number and diameter of primordial and primary follicles were similar in both groups. Electron microscopic studies revealed that in control group oocytes were separated from each other and were mainly in the form of primordial follicles. However, in the experimental group, they mainly were in the form of oocyte nests.Conclusion: The results indicate that tamoxifen suppresses oocyte DIFFERENTIATION at early stages but does not affect the development of already differentiated follicles.

چکیده: 

Aims Amniotic fluid stem cells have lower ethical limitations than embryonic stem cells for the use in research and treatment. These cells show great self-renewal potential and can differentiate into the specialized cells of all three germ layers. The amniotic fluid stem cells display minimal risks of teratomas and very low immunogenicity. For these reasons, amniotic fluid appears as a promising alternative source for stem cell therapy. The objective of this study was to isolate the stem cells from amniotic fluid and differentiate them into the osteoblastic cells. Materials & Methods An amniotic fluid sample (about 10ml) was collected from a healthy donor in Sarem women’ s hospital (Tehran, Iran). After centrifugation, the cells were cultured in a DMEM medium supplemented with 20% FBS. The cell clones were observed after two weeks and were passaged to an osteoblastic DIFFERENTIATION medium. Alizarin red staining and RTPCR for alkaline phosphatase and osteocalcin markers were used for confirmation of cellular DIFFERENTIATION. Findings Stem cells were isolated from amniotic fluid. Phenotypically, these cells showed spindle-shaped morphology with a large nucleus. Following the induction of DIFFERENTIATION, they showed the expression of osteoblastic cells markers indicating their DIFFERENTIATION. The expression of those markers was confirmed by immunocytochemistry and RT-PCR. Conclusion Amniotic stem cells have the ability to differentiate into the osteoblastic cells using an osteoblastic DIFFERENTIATION medium.

چکیده: 

Because children and adolescents have their own biological characteristics and the causes of crime are different, they also demand their own criminal judicial proceedings. This special judicial proceedings is known from two dimensions with special judicial protocols and special judicial institutions. In this article, differential judicial protocols are discussed. These protocols, both in the pre-trial stage and in the trial and post-trial stage, are aimed at protecting the guilty child and try to minimize the negative consequences of formal criminal judicial proceedings against these people, and therefore, based upon the more gentle view, has made the children the subject of semi-criminal or non-criminal actions in the trial process. Lack of investigation by law enforcement officers, prohibition of detention, non-disclosure of proceedings, creation of personality files and such measures are solutions that the legislator has considered and ruled in this process.
