Interaction of sperm with endometrium can regulate genes involved in endometrial receptivity pathway in mice: An experimental study

Background: Many researchers consider implantation and endometrial receptivity as pertinent issues in reproductive science. Although, several experiments have been performed and their results evaluated, yet there is no confirmed evidence about the related factors and the role of sperm in endometrial receptivity. Objective: To investigate the effect of the sperm-endometrium interaction in regulating genes involved in the endometrial receptivity pathway. Materials and Methods: In this experimental study, 10 male and 30 female NMRI mice were included, and half of the male cases were vasectomized. The subjects were divided into two groups as follows; group 1 (case) comprised of 15 females mated with 5 non-vasectomized male mice, while group 2 (control) consisted of 15 females mated with 5 vasectomized males. Cases were sacrificed and assessed after 36 hr and the endometrial tissue was extracted and kept at -80°C until the next use. The expression of the endometrial receptivity pathway genes, including VEGF, HBEGF, FGF2, EGF, LIF, LIFR, HOXA10, MUC1, PGR, and CSF, was examined in both groups. For statistical analysis, an independent samples test (Mean ± SD) was used. Results: The mRNA levels of LIF (p = 0.045), LIFR (p = 0.040), MUC1 (p = 0.032), VEGF (p = 0.022), EFG (p = 0.035), and FGF2 (p = 0.040) were significantly upregulated in the case group compared with the control group. Conclusion: Finally, seminal plasma was observed to be effective in expressing the involved genes in the successful implantation pathway, including LIF, LIFR, MUC1, VEGF, EGF, and FGF2. Key words: Endometrial receptivity, Sperm, Gene expression, Mice.

Aim. To detect the features of immune status at prenatal and early postnatal periods under the influence of Toxoplasma gondii antigens. Methods. The experimental study was performed on Wistar white rats, who were the offspring of the female rats who were sensitized by T. gondii corpuscular antigen during the III trimester of pregnancy - group 1 (n=96) and on animals who were administered T. gondii corpuscular antigen at firs day of life - group 2 (n=103). Control group consisted of intact rats. Common blood test, levels of antibody-forming cells and CD3+ cells were assessed at 60 day after birth. Results. Neutrophil blood count was 1.9 times higher in the group 1 rats compared to group 2. Eosinophil blood count was 1.4 times lower in the group 1 compared to control group (р=0.01), and 2 times lower in the group 2 compared to control group (р=0.002). At the same time, lymphocyte count was comparable in the group 1 rats and control group, while it was 1.4 times lower in the group 2 compared to control group (р=0.04). Together with that, there was a reduction of CD3+ cells and antibody-forming cells in blood and spleen, which was more marked in the 2nd group. Lymphoadenopathy, thymus dysgenesia, reduced blood and spleen T-cells levels, low humeral immunity were found in Wistar white rats, who were the offspring of the female rats who were sensitized by T. gondii corpuscular antigen during the III trimester of pregnancy. Conclusion. The influence T. gondii corpuscular antigen on rats during perinatal period results in secondary immunodeficiency, persisting at 60 day of life.

Abstract Background: investigate the prevalence and The related factors between the two types of premature ejaculation (lifelong PE[LPE], acquired PE [APE] in men and atherosclerosis. Methods: One hundred patients complaining of PE and 100 control subjects were enrolled in this prospective study.All cases underwent a full medical history and Clinical examination.Blood pressure,serum lipid profile, testosterone,and Body mass index (BMI) were measured.The Arabic index of premature ejaculation (AIPE) and self-estimated (IELT) Intravaginal latency time was used for PE evaluation. Atherosclerosis was diagnosed by measuring the Carotid artery intima-media thickness (CIMT). Patients were divided into two major groups, (Group 1) [PE group] and (Group 2) [Control group]. Results: The mean age of cases in (group1) and (group 2) were 44.5 ± 11.7 versus 42.3 ± 10.8 yrs. The Systolic BP, diastolic (BP), Serum Triglycerides, serum LDL (BMI), the prevalence of atherosclerosis and smoking rate showed higher results in (group1) compared to group2, with significant difference (p<0.001). The IELT was significantly lower in group1 (2.67± 1.25) compared to group2 (3.77±1.52), (p<0.001). The prevalence of APE (74%) was significantly higher than LPE (26%) in group1(p<0.001). regression analysis revealed that patients with APE showed more comorbidities than LPE patients concerning the prevalence of atherosclerosis, hypertension, and hyperlipidemia (p<0.001 for all items).Both of APE and LPE were significantly related to age>35y, BMI ≥ 25 kg/m2, smoking, Bl pressure and hyperlipidemia (p<0.001 for all factors).Conclusions: Both types of PE,predominately the APE type,are associated with atherosclerosis, hypertension, and hyperlipidemia. The APE type reported more prevalence than the LPE.

The aim of this study was to determine the role of transcutaneous electrical nerve stimulation (TENS) in the viability of random skin flaps. In 30 Wistar-EPM rats, a random 10×4 cm skin flap was raised and a plastic barrier was interposed between the flap and its bed. Immediately after surgery and for two subsequent days, the rats in group 1 (the control group) were anesthetized for 1 h with the electrodes positioned in the base of the flap and without the administration of the electric stimulus. The rats in group 2 (the treatment group) were submitted to TENS for 1 h immediately after the surgery and for two subsequent days. The percentage of necrotic area (averages of 43.11% in the rats in group 1 and 23.52% in the rats in group 2) was calculated on the seventh postoperative day in both groups. Statistical analysis proved that TENS was more efficient in increasing random skin flap viability than was the method used in the control group.

Mycobacterial infection(MI) is sometimes diagnosed using CT-guided transthoracic needle biopsy (TNB). However, the exact role of CT-guided TNB in this diagnostic process is not clearly known. The purpose of this study is to analyze the role of CT-guided TNB in patients with MI who present with a focal lung lesion. Of 1233 patients who underwent CT-guided TNB from January 2010 through February 2016 at our institution, patients with a final diagnosis of MI were included for analysis. Clinical characteristics and biopsy-related factors were compared between patients whose diagnosis could be established using TNB samples alone (group 1) and those whose samples from additional tests were necessary for diagnosis (group 2). We also analyzed the possible benefit of CT-guided TNB as compared with bronchoscopy in a subgroup who underwent both procedures. 47 patients with MI were included in the study, with 37 patients (78.7%) in group 1 and 10 patients (21.2%) in group 2. There was no statistically significant difference in clinical characteristics or biopsy-related factors between the two groups. Of 41 patients with MI who underwent both bronchoscopy and TNB, success in diagnosis was solely attributable to TNB in 16 (39.0%) patients; in 19 (46.0%) patients, diagnosis could be made based on bronchoscopy results alone. MI can be successfully diagnosed by CT-guided TNB in about 80% of patients with MI who underwent TNB, but 46% of the patients could have been diagnosed with bronchoscopy results alone. CT-guided TNB is inferior to bronchoscopy in the differentiation of Mycobacterium species even in peripheral lung lesions.

This study determined the utility and accuracy of susceptibility-weighted MRI (SWI) for the detection of carotid cavernous fistulas. We retrospectively compared SWI images in nine patients (Group 1, case group) of DSA-proved carotid cavernous fistula (CCF) and 19 DSA negative cases for CCF as a control group (Group 2). Group 1 was again sub-grouped into direct and indirect types. Using uniform region-of-interest measurements, signal intensity within the superior ophthalmic vein (SOV) and the superior sagittal sinus (SSS) were measured on magnitude images of SWI. The SOV/SSS signal intensity ratio was calculated in each case and the mean values of the two groups were compared. Eleven SOV/SSS signal intensity ratios in Group 1 (7 unilateral and two bilateral CCF), 38 in Group 2 (both sides in 19 control subjects) were included. Median ± interquartile range of SOV/SSS ratios for Group 1, Group 2, indirect and direct type CCFs were 1.07 ± 0.43, 0.39 ± 0.23, 0.83 ±0.29, 1.4 ±0.38 respectively. Mann-Whitney test between Groups 1 and 2 was statistically significant with P<0.0001. All cases and controls were reliably distinguished with SOV/SSS signal intensity ratio of 0.64 as cut-off. Direct CCF cases had consistently higher ratios than indirect CCF. SWI was highly sensitive for detection and differentiation of both direct and indirect CCF. Only one case of corticovenous reflux was missed by SWI. SWI is useful for detection of CCF and to differentiate between direct and indirect CCF.

Aim. The aim of this study is determination of the role of certain pro-inflammatory and anti-inflammatory cytokines in the pathogenesis of psoriasis. Material and methods. The 110 patients with plaque form of psoriasis of moderate severity were examined, who were divided into 2 groups. Group 1 includes 65 patients (43 men and 22 women) from 18 to 64 years old with a duration of disease from 1 year to 39 years. The traditional treatment (detoxification, antioxidant, antihistamine, multivitamin, membrane stabilizing, local anti-inflammatory) was prescribed to the patients of group 1. Group 2 includes 45 patients from 18 to 65 years old (31 men and 14 women) with a duration of disease from 6 months to 32 years. The alternative treatment (with traditional therapy, the hepatoprotectors was also used) was prescribed to the patients of group 2. The control group makes 18 practically healthy periodic donors (9 men and 9 women) from 19 to 57 years old. The level of IFNγ, TNFα, IL-1α, IL-2, IL-10 and TGFβ was investigated in the serum of psoriatic patients by ELISA (commercial kits of Demeditec Diagnostics GmbH were used). Results. Before the treatment, the significant increase of level of circulating pro-inflammatory cytokines and significant decrease of level of anti-inflammatory cytokines were seen in both groups of patients with psoriasis compared with the control group. After the treatment, the level of proinflammatory cytokines is significantly reduced and the level of anti-inflammatory cytokines is significantly increased in group 1, approaching to the normal values. In group 2, the level of proinflammatory cytokines decreases more than in group 1 after the treatment. The level of anti-inflammatory cytokines also increases more than in group 1 (high treatment efficiency). The intensity of the rate of decrease of PASI after treatment in patients of group 2 is at least 1.2 times higher than in I group, of DLQI after treatment in patients of group 2 is at least 1.44 times higher than in group 1. Conclusions. The registered changes in the serum of patients with moderate severity of papular-plaque form of psoriasis indicate their essential role in the pathogenesis of psoriasis.

PURPOSE: To verify the correlation between the presence of IH and the intensity of LUTS related to BPH quantified through the International Prostate Symptom Score (IPSS). METHODS: We prospectively selected 52 patients over the age of 55years; Patients were divided into 2 groups. Group 1: composed of 32 patients with IH; Group 2 (control group): composed of 20 patients with no clinical evidence of IH. All patients were assessed using the IPSS, uroflowmetry (Qmax), post-void residual urine volume (PVR) and prostate volume (PV). RESULTS: Groups 1 and 2 presented no difference in PV (p>0.05) and uroflowmetry (Qmax) (p>0.05). There was a statistical significant difference between the PVR mean values between groups 1 and 2. The presence of IH correlated with a higher IPSS score (r=0.38 p<0.05) despite the fact the no difference was detected between the incidence of patients with mild, moderate and severe LUTS in groups 1 and 2. CONCLUSION: Patients with IH present higher IPSS. The role of IPSS as a marker to predict the development of clinical IH still to be determined.

Aim To study the role of inflammation markers and endothelial dysfunction in predicting the risk of cardiovascular event following a percutaneous coronary intervention (PCI) in patients with ischemic heart disease (IHD) and metabolic syndrome (MS).Materials and methods 80 patients (72 men; median age, 56 (50;63) years) with IHD and PCI were evaluated. Based on the presence of MS according to NCEP-ATP III criteria, patients were divided into two groups, group 1 without MS (n=32) and group 2 with MS (n=48). The control age- and sex-matched group included 15 people without cardiovascular diseases. Serum concentrations of tumor necrosis factor α (TNFα), interleukin 6 (IL-6), IL-10, lipoprotein-associated phospholipase A2 (LP-PLA2), and endothelin 1 were measured by enzyme-linked immunosorbent assay (ELISA). Patients were followed up for 12 months after PCI with evaluation of the incidence of adverse cardiovascular events. Statistical analysis was performed with Statistica 10.0 and Medcalc 19.2.6 software. Differences between variables were considered statistically significant at р<0.05. Potential predictors were determined by the ROC analysis with construction of ROC curves, calculation of AUC (area under the curve), identification of COP (cut-off point by the Youden’s index), and sensitivity (Se) and specificity corresponding to the COP.Results Patients with MS had statistically significantly higher serum levels of inflammatory markers than patients of the control group. Concentration of the intravascular inflammation marker, PL-PLA2, was 2.7 times higher in group 1 and 5.1 times higher in group 2 than in the control group (р<0.001). Concentrations of endothelin 1 were 1.9 times higher in group 1 and 3.7 times higher in the MS group compared to the control. At one year after PCI, the incidence of adverse outcomes in the form of cardiovascular events was higher for patients with MS: 10 (20.8 %) cases of stent restenosis and 13 (27.1 %) episodes of coronary atherosclerosis progression according to results of repeated coronarography vs. 2 (6.3%) restenosis cases (χ2–10.853; р=0.002) and 2 (6.3%) episodes of atherosclerosis progression (χ2–23.651; р=0.001) for patients without MS. The groups did not differ in rates of myocardial infarction and cardiac death. The most significant predictors of unfavorable prognosis were LP-PLA2 concentration >983.83 ng/ml (area under the ROC curve, 0.867; sensitivity, 80 %; specificity, 100%; р<0.001) and endothelin 1 overexpression >0.852 fmol/ml (area under the ROC curve, 0.885; sensitivity, 85.5 %; specificity, 83.6 %; р<0.001).Conclusion Patients with MS were characterized by more pronounced imbalance of pro- and anti-inflammatory factors. Concentrations of LP-PLA2 >983.83 ng/ml and endothelin 1 >0.852 fmol/ml were shown to be predictors of unfavorable prognosis for patients with IHD and MS after PCI with coronary stenting.
