  • A Study on Testicular Development in Apteronotus albifrons

    • Abstract: Apteronotus albifrons has its cloacal aperture located in the front of the body and on the back of the lower jaw. A. albifrons possess a pair of testes attached on the mesentery below its liver on the back of the abdominal cavity. In the early days of development, the testes are in translucent elongated thin strips in nude colour. As they develop, the testes will grow thicker and become white or creamy white in color. The rear end of the testes will split whereas the front end will merge to form the vas deferens which is connected to the external environment through the cloacal aperture. Testes of A. albifrons are lobular. There are six stages in its development. At 6 months of age, the testis structure shows clear medium with primary spermatocytes and abundant spermatogonia, suggesting that development is into the stageⅡ. At 8 months of age, testes in male A. albifrons are in the shape of a thin rod in white with blood vessels in presence. Germ cells consist of spermatogonia, primary spermatocytes and spermatocytes, indicating stageⅢ development. At 11 months of age, testes in male A. albifrons grow fuller and are in creamy white with apparent blood vessels present. Primary spermatocytes, secondary spermatocytes, spermatids and a small amount of sperms are president, indicating stageⅣ of development. At 15 months of age, testes in male A. albifrons swells and consist of a large amount of sperms, reaching full maturity. This is the stageⅥof development, after which is the stage featured by testes after spermiation.

  • Comparison of Magnesium Sulfate and Nifedipine in Prevention of Preterm
           Labor

    • Abstract: Introduction: Fetal and neonatal complications are more common in premature than full term pregnancy. Treatment of preterm labor and postpone delivery increases neonatal survival and better quality of life and reduces health care costs for premature infants. This study aimed to compare the effects of Nifedipine and Magnesium sulfate in arresting preterm labor and to adverse the effects of these drugs.Materials and Methods: This randomized and clinical trial study was performed on 100 pregnant women who were hospitalized for preterm labor pain. The participants were pregnant women with the gestational age of 28 to 34 weeks and with a single pregnancy and symptoms of preterm were studied. They were randomly divided into two equal groups. After not suppressing the pain by fluid therapy, in the first group Magnesium sulfate infused injection (N=50) was performed, while in the second group, oral Nifedipine were given. The research uses SPSS software (version 20) statistical software issue 20 to analyze the result of tests with descriptive statistical methods including independent T test and chi square test.Results: Mean maternal age, gestational age, parity converted Magnesium sulfate and Nifedipine group had no significant difference in statistical analysis. Delivery was delayed more than 48 hours in 48% (24 person) of cases in the Magnesium sulfate group and in 72% (36 person) in Nifedipine group (p=0.03). A statistically significant difference in response to treatment was more in group of Nifedipine.Conclusion: The results showed that Nifedipine is more effective than Magnesium sulfate in postponing delivery (more than 48 hours), producing minimal side effect, having adequate price and applying an easy use method. Therefore, Nifedipine, as a tocolytic, can be a good substitute for Magnesium sulfate in preterm labor treatment.

  • Study of Anticancer Activity of Pratensein and Pratensein Glycoside
           Isolated from Cuscuta kotchiana

    • Abstract: In the present paper, we demonstrate that extract of Cuscuta kotchiana is able to inhibit in vitro proliferation of two human breast cancer cell lines, MCF-7 and MDA-MB-231. The expression levels of p53, bcl-2, caspase-3 and bax genes at the mRNA and protein levels were evaluated using quantitative Real Time PCR and western blot analysis. The most active fractions of C. kotchiana were detected by NMR as pratensein and pratensein glycoside. The cytotoxic activity of pratensein glycoside was significantly more than pratensein. The expression level of bcl2 gene was decreased in cancer cells treated by both compounds at CC50 concentrations. But the expression levels of caspase-3, p53 and bax genes were increased in treated cancer cells. In conclusion, all the data demonstrated that the glycoside form of pratensein is important agent in inducing apoptosis in human breast cancer cells.

           Rheumatic Mitral Stenosis Patients

    • Abstract: Introduction: Rheumatic mitral stenosis (MS) is a common valvopathy in developing countries that requires invasive or minimally invasive treatment. There is scarcity of data regarding the long term follow up of treated MS patients.Aim: The aim of this study was to compare the long-term outcomes of biologic and mechanical prosthesis and percutaneous transvenous mitral commissurotomy (PTMC) in treated MS patients.Materials and Methods: This historical cohort study was conducted on treated MS patients who underwent treatment in a tertiary hospital in Mashhad, Iran. Treated MS patients were identified and asked to refer to the center for follow up. Demographic characteristics and type of treatment intervention were obtained from patient records. The follow up assessment included history of PTMC, readmission and echocardiography to assess trans mitral gradient (MG), size and function of right ventricle (RV) and the presence and severity of other valvopathies.Results: A total of 135 patients (21.5% males and 78.5% females) with the mean age of 43.68 ± 11.17 years old participated in the study. The most common intervention method was mechanical valve (61.5%) followed by PTMC (24.4%) and biologic valve (14.1%). Median follow up duration was 4 years. Majority of subjects (52.6%) remained asymptomatic and the functional class was reduced significantly compared to baseline. MG was significantly higher in PTMC and biological valve group compared to mechanical valve p

  • Correlation Between mpMRI Staging and Final Surgical Pathology in Prostate
           Cancer

    • Abstract: Purpose: We evaluated the role of multiparametric magnetic resonance imaging (mpMRI) in the diagnosis of prostate cancer and predicting of surgical staging of prostate cancer.Materials and Methods: The study was done in 110 subjects who got mpMRI before radical prostatectomy in our hospital from 2016 to 2019. Preoperative mpMRI findings of 110 were compared to surgical pathology results following radical Prostatectomy. A comparison was made between pathologic staging of prostate cancer and the mpMRI findings.Results: pathologic evaluation confirmed prostate cancer foci (237) were recognized in 110 subjects. Generally, mpMRI sensitivity of 46.4% was found for prostate cancer detection (110/237). Pathological tumor volume was a significant predictor of prostate cancer detection using mpMRI. In 33% of the cases, the pathologic staging is precisely similar to mpMRI and in 43%of the cases, there was a slight difference between the pathologic staging and staging by mpMRI but the cancer was confined to the prostate.in 24% of the cases, there was a significant difference between the pathologic staging and staging by mpMRI. The mpMRI was not able to identify the significant cancer in 24% of the cases.Conclusion: The preoperative mpMRI was useful in detecting prostate cancer and in predicting surgical staging. However, the detection of 24% of clinically significant cancer was missed using mpMRI. As we move toward personalized medicine, use of MRI to biopsy each man's prostate differently rather than based on a pre-defined 12 core seems to be supported in the recent literature.
