Removal of copper from aqueous solution using perlite
No full text2nd International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 18-21, 2017 -- Antalya, TURKEYThe wastewaters containing organic and inorganic pollutants after many industrial processes such as metal plating, mining, textile, alloy, battery and industrial chemicals, are often discharged to environment. Heavy metals among these pollutants have highly stable, toxic, non-degradable and carcinogenic characters. They affect not only ecological system, but also human health and many life forms. Therefore, these contaminants should be eliminated or reduced to allowable levels before releasing to environment. Most of heavy metals have toxic character even at low concentrations of about 0.1-0.3 ppm. Treatment technologies such as filtration, ion exchange, precipitation, electrodeposition, reverse osmosis, sedimentation, and adsorption have been applied for removal of heavy metals from aqueous solutions. Adsorption is one of the most common and widely applied methods to eliminate the metal ions from waste solutions because of its simplicity and cost effectiveness. Activated carbon, clay minerals, ion exchange resins and various agricultural residues can be used as adsorbent materials in this process [1-3].Agri Ibrahim Cecen Univ,IC FdnScientific Research Projects Coordination Unit of Munzur University [MFTUB014-03]This work was supported by The Scientific Research Projects Coordination Unit of Munzur University (Project No: MFTUB014-03)
Top 100 Articles on Artificial Intelligence in Urology
No full textArtificial intelligence (AI) is rapidly increasing its importance in many fields today, including medicine and even urology. In this article, we have compiled the top 100 articles on this topic to provide insights into and guide future research for researchers. We selected the best-matched articles from 2019-2024 by typing “AI in urology” into the search bar on PubMed’s website. We accepted the terms deep learning, machine learning, and neural networks. We have excluded the editorial letter and comments from the study. We reviewed 231 articles and selected the top 100 articles. We categorized the articles based on the date of printing, publication types, related sub-specialties, journal names, the quartile indexes of these journals, the number of references, and citations, the country of affiliation of the first author, and the number of centers involved. Every year, researchers are delving deeper into this topic. Currently, the majority of articles are review articles. High-quality journals are publishing studies on this topic. Researchers from America and Europe are the leading figures in this field. In AI, researchers focus the most on uro-oncology, which is the subspecialty of urology. We anticipate a substantial increase in the use of AI in urology in the future. It is imperative to acknowledge that there are numerous disadvantages, in addition to the advantages. Numerous original articles are necessary
HIV-associated non Hodgkin lymphoma: A case series study from Turkey
No full textBackground: Human immunodeficiency virus (HIV) is a global health concern with major risks for opportunistic infections and predisposition to malignancies including Kaposi sarcoma associated with Human Herpes Virus-8 (HHV8) and non-Hodgkin lymphoma (NHL) commonly associated with Epstein Barr Virus (EBV). Although the exact mechanisms of predisposition to certain malignancies are unclear, HIV (+) cancer patients typically have poorer prognosis.Materials and Methods: We included all five HIV positive NHL patients receiving antiretroviral therapy (ART) and chemotherapy in our clinic and aim to determine their follow-up outcomes associated with ART.Results: The use of ART in conjunction with chemotherapy regimens lead to better therapeutic outcome in our cases with no mortality over three years of follow-up despite high rates of poor prognostic factors and studies demonstrating 1-year survival rates of approximately 30% in HIV-associated lymphoma. No significant adverse effect has been recorded.Conclusion: We recommend use of ART along with chemotherapy regimens in HIV positive lymphoma patients for better treatment response.

The Effects of Microsurgical Varicocelectomy Performed for Infertility on Premature Ejaculation
No full textPurpose: To investigate the effects of varicocelectomy on premature ejaculation (PE) in patients with varicocele and infertility. Methods: A total of 82 sexually active patients aged 18 years or over who had undergone microscopic subinguinal varicocelectomy with a clinical diagnosis of varicocele in 14 urology clinics between October 2021 and March 2023 with primary infertility were evaluated prospectively Patients were evaluated using the Turkish validated form of the ‘Premature Ejaculation Diagnostic Tool’ (PEDT) scale. A PEDT score of 11 or above was taken to indicate the presence of PE. Turkish validated forms of PEDT and International Index of Erectile Function-5 (IIEF-5) were completed in all patients pre-operatively and at 3 and 6 months post-operatively. Intravaginal ejaculatory latency time (IELT) and serum testosterone measurements were also recorded. Results: Left varicocelectomy was performed in 70.7% and bilateral varicocelectomy in 29.3% of the participants. A significant difference was found between pre- and post-operative PEDT scores (× 2 (2) = 130.1, p 0.001). A significant difference was observed between pre- and post-operative IELT time (× 2 (2) = 143.2, p 0.001). IIEF-5 scores differed before and after surgery (× 2 (2) = 59.5, p 0.001). A difference was found between the testosterone levels measured before and after surgery (× 2 (2) = 40.9, p 0.001). No statistically significant difference was observed between the third- and sixth-month testosterone values (p = 0.183). Testosterone levels (p = 0.001) and IELT scores (p 0.001) were significantly higher, while PEDT scores (p 0.001) were significantly lower in the bilateral varicocelectomy group at the sixth post-operative month. Conclusion: In light of our findings, it is recommended that infertile patients with varicocele be informed of the positive effects of varicocelectomy on PE. © The Author(s), under exclusive licence to Springer Nature B.V. 2024
Cellular and immune landscape of chronic liver diseases: insights from immunophenotyping
No full textBackgroundChronic liver disease due to alcohol-related liver disease and chronic viral hepatitis pose a substantial burden on healthcare systems. Chronic liver disease may predispose to hepatocellular carcinoma, for which therapeutic options are limited. This study aimed to explore the immune cell characteristics of the clinical conditions.MethodsExplant liver samples were collected from 25 patients for bulk RNA sequencing and flow cytometry analysis. Immune cell populations were characterized by flow cytometry from isolated hepatic and peripheral mononuclear cells.ResultsSignificant differences in immune cell characteristics were observed among patients with three clinical conditions. Viral hepatitis and peri-tumor samples exhibited higher hepatic B cell counts compared to alcohol-related liver disease. Additionally, chronic liver disease patients showed higher levels of CD57+ T cells, suggestive of T cell differentiation. Differential expression analysis identified several genes associated with immune regulation, including downregulation of CD27 and upregulation of granzyme B in ARLD, consistent with a highly differentiated phenotype. LAG3 and PDCD1 were upregulated in peri-tumor samples. The NK cell count was lower in peri-tumor liver specimens compared to ARLD, and an upregulation of TIGIT, an inhibitory marker, was observed in those peri-tumor specimens.ConclusionThis study contributes to the understanding of immune dynamics in chronic liver disease among different etiologies. B lymphocytes are relatively reduced in alcohol-related liver disease compared to other groups, and T cells exhibit a more differentiated subtype. The peritumor microenvironment in HCC suggests a relatively diminished presence of NK cells and a potential tendency toward increased inhibitory characteristics

The Role of Obesity in Predicting the Clinical Outcomes of COVID-19
No full textIntroduction: The aim of this was to describe the predictors of mortality related to COVID-19 infection and to evaluate the association between overweight, obesity, and clinical outcomes of COVID-19. Methods: We included the patients >18 years of age, with at least one positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients were grouped according to body mass index values as normal weight <25 kg/m2 (Group A), overweight from 25 to <30 kg/m2 (Group B), Class I obesity 30 to <35 kg/m2 (Group C), and ≥35 kg/m2 (Group D). Mortality, clinical outcomes, laboratory parameters, and comorbidities were compared among 4 groups. Results: There was no significant difference among study groups in terms of mortality. Noninvasive mechanical ventilation requirement was higher in group B and D than group A, while it was higher in Group D than Group C (Group B vs. Group A [p = 0.017], Group D vs. Group A [p = 0.001], and Group D vs. Group C [p = 0.016]). Lung involvement was less common in Group A, and presence of hypoxia was more common in Group D (Group B vs. Group A [p = 0.025], Group D vs. Group A [p < 0.001], Group D vs. Group B [p = 0.006], and Group D vs. Group C [p = 0.014]). The hospitalization rate was lower in Group A than in the other groups; in addition, patients in Group D have the highest rate of hospitalization (Group B vs. Group A [p < 0.001], Group C vs. Group A [p < 0.001], Group D vs. Group A [p < 0.001], Group D vs. Group B [p < 0.001], and Group D vs. Group C [p = 0.010]). Conclusion: COVID-19 patients with overweight and obesity presented with more severe clinical findings. Health-care providers should take into account that people living with overweight and obesity are at higher risk for COVID-19 and its complications
Non-abstractness as mental simulation in the representation of number
No full textAbstraction is instrumental for our understanding of how numbers are cognitively represented. We propose that the notion of abstraction becomes testable from within the framework of simulated cognition. We describe mental simulation as embodied, grounded, and situated cognition, and report evidence for number representation at each of these levels of abstraction.</p
