This study was aimed to identify the most frequently observed pathogens in uncomplicated urinary tract infections from outpatient urinary isolates obtained across seven different geographical regions in Türkiye and to determine whether the antibiotic resistance rates of these pathogens differ significantly between these regions. The study included patients aged 18 to 65 years who were diagnosed with uncomplicated urinary tract infections and had positive urine cultures from March 2021 to August 2022, across 37 different centers in Türkiye. The participating centers were selected based on their use of the disk diffusion method, in line with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines, to ensure standardization of urine culture data.

In the present study, the effects of coenzyme Q10 (CoQ10), which is widely used in daily life, on the methotrexate (MTX)-induced hepatotoxicity, which is widely used today in malignancies and autoimmune diseases, were examined. Twenty-four female Wistar albino rats were divided into four groups. The group 1 ( = 6) was given 1 mL corn oil by oral gavage (p.

Article Synopsis
  • This study compared the effects of continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) on left ventricular function in patients undergoing maintenance dialysis.
  • A total of 47 patients participated, with echocardiography used to assess various measures of left ventricular health, revealing that those on CAPD had significantly higher muscle mass and rates of diastolic dysfunction and left ventricular hypertrophy.
  • The findings indicate that long-term CAPD treatment is associated with worse left ventricular function compared to HD, highlighting the need for further attention to heart health in patients on CAPD.

ICSI is one of the most commonly used techniques to treat infertility. The sperm selection for the procedure is done 'randomly' by the embryologist according to the motility and morphology parameters which is known not to reflect the potential of a sperm for fertilization, pregnancy and a healthy childbearing. Since the apoptosis rate is higher in sperm cells of infertile patients, it is more likely to choose an apoptotic sperm by the 'random selection method'.

Article Synopsis
  • This study compares two surgical methods, Hartmann's procedure (HP) and resection with primary anastomosis (RPA), for treating acute left-sided colonic emergencies among 1215 patients from 204 centers globally.
  • Results showed that while HP was the more common treatment (57.3%), RPA was favored for younger patients with fewer health issues and those needing surgery sooner.
  • The study concluded that although HP is still widely used, RPA might be the better option, emphasizing the importance of patient characteristics and surgeon experience in determining treatment choice.

Honey bees have a great economic importance both in Turkey and in the world due to the products they produce and their contribution to pollination. For this reason, many microflora and microbiota studies have been conducted on bees. While these research were primarily focused on pathogen isolation, the ecological roles of non-pathogenic flora members and how they may be used are now being studied more extensively.

Titanium (Ti)-based implants are not compatible enough due to their bio-inert character, insufficient antibacterial capabilities and stress-shielding problem for dental and orthopaedic implant applications. Thus, this work focused to fabricate, analyze and improve antibacterial properties titanium dioxide (TiO) nanotube array surfaces on Ti foam by anodic oxidation (AO) process. The well-ordered nanotube arrays with approximately 75 nm were successfully fabricated at 40 V for 1 h on Ti foams.

The aim of the present study was to investigate whether patients with psoriasis are prone to urolithiasis. Prospective analysis of 67 patients diagnosed as psoriasis (PS group) and 65 volunteers who had never been diagnosed as psoriasis (NPS group) was performed. The levels of oxalate, citrate, calcium, uric acid, magnesium, creatinine, and sodium were evaluated by analyzing the 24-h urine samples.

This study aims to investigate the Turkish validity and reliability of the International Fitness Scale (IFIS) and the Self-Perceived Health-Related Physical Fitness Questionnaire for Children (SPHQ-C) aged 10-17. The measurement tools were translated into Turkish by two independent researchers and back-translated. Then, the content validity was established with a group of 13 individuals (Sample 1) who presented to the sports medicine clinic.

The high sulfate content in various alkaline wastes, including those from fossil fuel and biomass combustion, and other industrial processes, necessitates careful management when used in cementitious systems to prevent potential deterioration of construction materials and environmental safety concerns. This study explores the under-researched area of high-sulfur fly ash (HSFA) utilization in the production of cement-free monoliths through accelerated carbonation and further examines the effect of niobium slag (NS)-a calcium aluminate-containing slag-as an additive on the strength development and the mobility of SO. The methodology involves mineralogical and microstructural analyses of monoliths before and after carbonation, accounting for the effects of accelerated carbonation treatment and NS addition.

  • The research focuses on enhancing the properties of commercial pure titanium (cp-Ti) for implants by creating Zn-deposited nanotube surfaces using anodic oxidation and physical vapor deposition methods.
  • The Zn-deposited surfaces were found to be hydrophobic, unlike the hydrophilic bare titanium surfaces, and exhibited increased corrosion current density due to the biodegradable nature of Zn.
  • Additionally, the Zn-deposited nanotube surfaces showed improved cell viability, alkaline phosphatase activity, and antibacterial properties, making them promising candidates for orthopedic and dental implants.
