Blocking the Cleavage of Filamin A by Calpain Inhibitor Decreases Tumor Cell Growth.

Background/aim: Filamin A (FLNA) is the most abundant and widely expressed isoform of filamin in human tissues. It is cleaved by calpain at the hinge 1 and 2 domains, producing a 90-kDa carboxyl-terminal fragment (FLNA). Recently, it has been shown that FLNA mediates cell signaling and transports transcription factors into the cell nucleus.

Use and Evaluation of Newly Synthesized Fluorescence Probes to Detect Generated OH• Radicals in Fibroblast Cells.

Reactive oxygen species (ROS) are pro-oxidant molecules synthesized in body with various functions and are essential for life. Increasing in reactive oxygen species or decreasing in antioxidants level cause oxidative stress which is very harmful. OH• radical is one of ROS's, with tendency to bind to lipids, DNA and proteins which cause irreversible damage in cells.

Effect of hydroxyethyl starch 130/0.4 on ischemia-reperfusion determinants in minor lower extremity surgery with tourniquet application.

Study Objective: To investigate the effect of 6% hydroxyethyl starch (HES) (130/0.4) infusion on ischemia-reperfusion determinants in minor lower extremity operations with tourniquet application.

Design: Prospective, randomized, clinical trial.

Resveratrol reduces matrix metalloproteinase-2 activity induced by oxygen-glucose deprivation and reoxygenation in human cerebral microvascular endothelial cells.

The main pathophysiology in cerebral ischemia is the structural alteration in the neurovascular unit, coinciding with neurovascular matrix degradation. Among the human matrix metalloproteinases (MMPs), MMP-2 and -9, known as gelatinases, are the key enzymes for degrading type IV collagen, which is the major component of the basal membrane that surrounds the cerebral blood vessel. In the present study, we investigated the effects of resveratrol on cytotoxicity, reactive oxygen species (ROS), and gelatinases (MMP-2 and -9) in human cerebral microvascular endothelial cells exposed to 6 hours of oxygen-glucose deprivation and a subsequent 24 hours of reoxygenation with glucose (OGD/R), to mimic ischemia/reperfusion in vivo.

Special-study modules in a problem-based learning medical curriculum: an innovative laboratory research practice supporting introduction to research methodology in the undergraduate curriculum.

We describe the organization of wet-lab special-study modules (SSMs) in the Central Research Laboratory of Dokuz Eylül Medical School, Izmir, Turkey with the aim of discussing the scientific, laboratory, and pedagogical aspects of this educational activity. A general introduction to the planning and functioning of these SSMs is given, along with specific examples. The wet-lab SSMs incorporate several innovative pedagogies: problem-based learning, research-based learning, practical laboratory education, team-based learning, and project-based learning.
