Comparison of Capillary Zone Electrophoresis with High-pressure Liquid Chromatography in the Evaluation of Hemoglobinopathies.

Objective: The capillary zone electrophoresis (CZE) and high-performance liquid chromatography (HPLC) methods were compared in terms of HbA2 measurement for the assessment of hemoglobinopathies.

Materials And Methods: CZE was compared with HPLC for the evaluation of patients without hemoglobinopathy (n=321), with β-thalassemia trait (n=113), and with common (HbD-Punjab, E, C, S/A, and S/S) and rare (HbS/D, O-Arap, Lepore, G-Coushata, Setif, Hamadan, Q-Iran, and H) variants (n=21). The reference range for HbA2 was determined by CZE.

The effects of facial mask use on ocular surface parameters and tear film cytokine profile in prolonged use.

Objective: To compare tear fluid levels of matrix metalloproteinase 9 (MMP-9) and IL-1ß cytokines between healthcare workers wearing facial masks and controls with correlations in clinical findings.

Methods: In a prospective, controlled clinical trial tear fluid was analyzed for MMP-9 and IL-1ß levels using a commercially available test (Invitrogen; Thermo Fisher Scientific Inc. Waltham, Massachusetts, USA).

Pediatric reference intervals for Free Testosterone, 17-OH Progesterone, Androstenedione, and IGF-1 with chemiluminescence immunoassay.

Background: The aim of the study was to produce age and sex specific pediatric reference intervals (RIs) on a fully automated chemiluminescent immunoassay (CLIA) system.

Material And Method: A total of 1586 patients' remnant sera were included in the study and free testosterone (FT), 17-OH progesterone (17OHP), androstenodione (A4) and insulin-like growth factor-1 (IGF-1) parameters were measured on MAGLUMI 2000 (Shenzhen New Industries Biomedical Engineering Co., Ltd.

Serum apelin-13 levels and total oxidant/antioxidant status of patients with Alzheimer's disease.

Objective: We aimed to evaluate apelin-13 levels, total oxidant/antioxidant status in Alzheimer's disease (AD) and to investigate the relationship between these parameters.

Methods: Patients newly diagnosed with AD were enrolled in the study. The control group consisted of age- and gender-matched healthy individuals.

Is Prevention of Hemolysis Possible in Blood Samples Collected from IV catheters in the Emergency Department?

Background: The effectiveness of aspiration and vacuum filling method with an adaptor in reducing hemolysis was investigated.

Methods: The study was conducted in the yellow zone of the Emergency department. Two different apparatuses that draw blood with two different techniques from an IV catheter were compared with our routine procedure.
