Background And Objectives: Mean platelet volume (MPV) is a potential marker of platelet reactivity. Increased MPV levels are shown to be the predictor of cardiovascular diseases, hypertension, and stroke. Previous studies demonstrated increased MPV levels in patients with obstructive sleep apnea syndrome (OSAS).

Aim: This study was designed to investigate the function of outer hair cells and medial olivocochlear efferents in type II diabetes mellitus (DM).

Materials And Methods: There were 50 patients with type II DM and 51 age- and sex-matched healthy controls included in the study. Both groups were compared in terms of transient evoked otoacoustic emissions (TEOAEs), distortion product otoacoustic emissions (DPOAEs), and contralateral suppression of TEOAE.

To evaluate the effects of hypercholesterolemia on the relaxation function of the urinary bladder, we examined the physiological mechanisms involved in the isoproterenol-induced relaxation in isolated detrusor strips in vitro and voiding behavior in vivo in rats. Adult male Sprague-Dawley rats were fed standard (control, N = 16) or 4 % cholesterol diet (hypercholesterolemia, N = 17) for 4 weeks. Concentration-response curves for isoproterenol-induced relaxations in carbachol-precontracted detrusor muscle strips were recorded.

Pancreatic islet transplantation is an alternative treatment of insulin replacement therapy in diabetes mellitus, but the islets are exposed to many chemical, mechanical damages, and oxidative stress before transplantation. Carvacrol is a well-known essential oil for its antioxidant, antimicrobial, antifungal and antiinflammatory properties. The aim of this study was to investigate the possible protective effects of carvacrol against H 2O 2 induced cellular injury on isolated pancreas islets.

Objective: To examine the efficacy of trospium chloride and tolterodine on the renal parenchymal inflammatory process and upper urinary dilation in rats with chronic partial upper urinary tract obstruction.

Materials And Methods: A total of 32 rats were divided into 4 groups: group 1, control; group 2, obstruction; group 3, obstruction plus tolterodine; and group 4, obstruction plus trospium chloride. In all groups, except for group 1, partial upper urinary tract obstruction was induced by embedding the upper quarter of the right ureter into the psoas muscle for 14 days.

Article Synopsis
  • The study aimed to explore how a high-cholesterol diet affects the contraction of detrusor smooth muscle in rats, which may indicate changes in bladder function.
  • Adult male rats were divided into a control group and a group fed a 4% cholesterol diet for 4 weeks; their muscle contractions were tested in response to potassium and carbachol.
  • Findings revealed that while cholesterol levels increased and detrusor contractions in response to potassium were heightened in the high-cholesterol group, the underlying mechanisms were affected differently, suggesting a link between hypercholesterolemia and urinary bladder function alterations.

Isotretinoin is widely used in the treatment of extensive and nodulocystic acne. The objective of this prospective study was to investigate whether oral isotretinoin could affect the hearing system. Thirty-eight patients with acne vulgaris (76 ears) who were diagnosed and treated at the Department of Dermatology were included in the current study.

Objective: Celiac disease (CD) is a gluten-triggered immune enteropathy caused by a genetic predisposition. Recent papers suggest that CD is increasingly recognized by extraintestinal findings. The aim of this study was to investigate the effect of CD on hearing pathway including the olivocochlear efferent system in children.

Article Synopsis
  • Toluene, a common industrial organic solvent, negatively impacts cell membranes by accumulating within them, leading to oxidative stress and damage in human erythrocytes (red blood cells).
  • The study assessed the effects of toluene on osmotic fragility, oxidative stress markers, and antioxidant activities in erythrocytes from individuals exposed to toluene and from lab treatments.
  • Results showed that toluene exposure increased oxidative stress and lipid/protein damage; however, it also had membrane-stabilizing effects, which surprisingly reduced osmotic fragility under certain conditions.

We intended to study the effect of swimming exercise on the brain, liver and heart malondialdehyde (MDA) levels which are the last product of oxidation, and to compare them with the brain, liver and heart MDA levels of controls. The experiments were carried out on 20 Wistar rats which were fed with a standard laboratory chow diet ad libitum. Rats were distributed in two groups, control group (n = 10) and exercise group (n = 10).
