Background Pesticides are widely utilized worldwide to control undesirable life forms during the planting procedure in agriculture. But they can pollute the nature and jeopardize human wellbeing. Additionally, on account of high resistance and biological activity; pesticides are able to accumulate in living organs and lead to acute and long-term negative effects along with toxicity. Milk and dairy products constitute an important part of a humans' diet since they contain fundamental supplements and nutrients, however they may also be the source of unhealthy components including pesticides. Therefore efficient, accurate and sensitive determination methods must be improved to quantify pesticide residues in these food samples. Results Multivariate optimization strategy was employed to optimize an efficient and robust liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) method for the determination of 156 pesticide residues in milk and dairy products. Three independent variables considered and their levels in the Box-Behnken design were as follows initial percentage of eluent A in mobile phase (30, 40, 50%), flow rate of the mobile phase (0.1, 0.2, 0.3 mL min-1 ), and ammonium formate concentration in mobile phase (0.0, 0.5, 1.0 mmol L-1 ). Favipiravir solubility dmso Under optimized conditions, average recoveries of target analytes were obtained in the range of 70.38% to 119.04%. Detection and quantification limits ranged from 0.06 to 2.70 μg kg-1 and from 0.22 to 8.10 μg kg-1 , respectively. Conclusion The validated method was successfully implemented to the analysis of 20 milk and dairy products including cream, cheese and yogurt. This method could be applied in many laboratories to reduce analysis time and cost. © 2020 Society of Chemical Industry.Purpose To compare the effects of microfluidic sperm sorting, density gradient and swim-up methods on the oxidative reduction potential (ORP) of split semen samples from a single patient population. Materials and methods A prospective controlled study was conducted to compare the effects of three different semen processing methods using split semen samples from the same population of infertile men. The primary outcome was the ORP. Secondary outcomes were the sperm concentration, progressive motility rate and total sperm motility. Results A total of 57 split semen samples were included in this study. The ORP was significantly lower in the microfluidic group compared to the density gradient and swim-up groups (p less then 0.05). The ORP/sperm concentration ratio was significantly lower in the microfluidic and density gradient groups compared to the swim-up group (p less then 0.05).Total sperm concentration was significantly higher in the density gradient group than the microfluidic and swim-up groups (p less then 0.05). Motility was significantly higher in the microfluidic and swim-up groups than the density gradient group (p less then 0.05). The progressive motile sperm rate was significantly higher in the microfluidic and swim-up groups than the density gradient group (p less then 0.05). Conclusions Microfluidic sperm sorting was better for selecting highly motile sperm and yielded a lower ORP than conventional sperm preparation methods.Persistent müllerian duct syndrome (PMDS) in the majority of cases is discovered during surgery for inguinal hernia or cryptorchidism. A transverse testicular ectopia (TTE) with cryptorchidism may be very rarely associated to PMDS. Assuming that müllerian remnants have a very low malignant degeneration potential if compared to the malignancy risk of an undescended and not relocated testis, we describe a simplified surgical technique of orchiopexy that avoids an extensive anatomical dissection, in this way minimizing the risk of losing the deferential blood supply to the testis.Purpose To evaluate the evidence that could help health system policy makers to approach the preference for same-gender urologists. Methods We performed this systematic narrative review according to the PRISMA guidelines. We searched MEDLINE, Web of science, EMBASE, CINAHL and Google Scholar for articles focused on the preference for patient-urologist gender similarity in the male-dominated department from 1999-2019. Finally, a narrative synthesis of studies meeting the inclusion and quality criteria was conducted in accordance with the nature of the evidences. We applied a thematic analysis using inductive approach for synthesizing studies employing heterogeneous research methods and designs. Results Of 208 titles and abstracts screened, 23 were included and three major themes including Reasons, Impacts, and Implications were identified. Overall, patients with urologic problems prefer same gender urologists and females were more likely to prefer the same gender urologist than males. Many women delays care due to a perceived lack of female urologists. The major identified reasons for the same-gender preference are religious believe, cultural background, emotional relationship, past experiences, and sensitive examinations. The results indicate that the urologists-patients gender similarity improves the quality of primary care. Our review reveled that Urologists prefer to perform more same gender-specific procedures. Beside, Female urologist and residents perceived to underestimate from their male counterparts. Conclusion This study could help health system to honor the patient's preference for same gender urologist. The findings may help medical education and health policy makers to move the male-dominated urology departments towards a culture supportive of female urologists.To analyze the predictive factors causing ischemic priapism following penile doppler ultrasonography (PDU) with intracavernosal papaverine injection Materials and methods Medical records of 467 patients who underwent PDU examination following intracavernosal papaverine injection for erectile dysfunction (ED) between 2009 and 2017 were retrospectively reviewed. Patients with hematological disease anamnesis, patients taking phosphodiesterase-5 inhibitor, patients with intracavernosal injection therapy anamnesis and patients who underwent PDU with other intracavernosal vasodilator drugs other than papaverine were excluded from the study. The remaining 268 patients were divided into two groups as priapism (38 patients) and non-priapism (230 patients). The groups were compared in terms of demographic data, American Society of Anesthesiologists (ASA) score, comorbidities, international index of erectile dysfunction (IIEF) score and PDU results. The significant parameters were analyzed with binary logistic regression analysis.
