Objective: Cancer stem cells (CSCs) have important roles in survival and chemoresistance. These cells are commonly recognized with CD44 and CD24 markers. In this study, we aimed to analyze the effects of mtDNA content on cell surface positivity for anti-CD24 and anti-CD44 antibodies and chemoresistance level in AGS, HGC-27 and MKN-45 gastric cancer (GC) cell lines and to determine a setpoint for mtDNA copy for each cell line.

Although they are relatively slow growing and low grade, chordomas are highly recurrent, aggressive, locally invasive, and prone to metastasize to the lungs, bone, and the liver. Chordomas highly and generally show a dual epithelial-mesenchymal differentiation.

Materials And Methods: A total of 79 pregnant women in their third trimester, including 33 passive smokers, 23 active smokers, and 23 nonsmoking controls, were enrolled in the study. Fetal biophysical indices were evaluated with B-mode scanning, whereas blood flow waveforms of uterine, umbilical, and fetal middle cerebral (MCA) arteries were analyzed with Doppler ultrasonography.
In this prospective randomized clinical trial, we aimed to evaluate the safety and efficacy of endourethrotomy with holmium:yttrium-aluminium-garnet (HO:YAG) laser and compare the outcomes with the conventional cold-knife urethrotomy. Fifty-one male patients with single, iatrogenic, annular strictures of the urethra were randomly divided into two groups; 21 patients who underwent direct-vision endoscopic urethrotomy with Ho:YAG laser (15 W; 1,200-1,400 mJ; 8-12 Hz) at 12 o'clock position (laser group) and 30 patients who underwent direct-vision endoscopic urethrotomy with cold-knife incision at 12 o'clock position (cold-knife group). The results obtained were analyzed and compared at 3 months, 6 months, 9 months, and 12 months postoperatively by clinical evaluation, uroflowmetry, and retrograde urethrographies.

Methods: A total of 88 patients who underwent 165 SWL sessions for renal or ureteral stones in our institution were included in the study. The degree of pain perception during the procedure was evaluated with a 10-point visual analog scale.

Background And Purpose: This prospective, randomized, and double-blind clinical study aimed to assess the analgesic efficacy of single-dose intramuscular (IM) injection of dexketoprofen (group DE) compared with single-dose IM injection of diclofenac (group DI) in patients who were undergoing shockwave lithotripsy (SWL).
Patients And Methods: A total of 70 men with single renal or ureteral stones were randomly separated into two groups. The 40 men in group DI received 75 mg IM diclofenac sodium and 30 men in Group DE received 50 mg IM dexketoprofen trometamol 30 minutes before SWL.
Objectives: To compare the efficacy of a folkloric medicinal plant extract (Ankaferd Blood Stopper [ABS]) with that of oxidized cellulose (Surgicel) in a life-threatening renal injury model. ABS is a mixture of 5 plants that has historically been used in Turkish traditional medicine. It has been approved by the Ministry of Health to manage external hemorrhage and dental surgery bleeding in Turkey.
