Structural, Functional and Molecular Dynamics Examination of a de novo cloned Otopetrin-like Proton Channel in crayfish.

Proton channels play a crucial role in many biological functions, as they are responsible for the selective transport of protons across cell membranes. Recently, Otopetrins, a family of eukaryotic proton-selective ion channels, have attracted significant attention due to their diverse physiological roles. Despite the importance of Otopetrins, their structural and functional properties remain relatively unexplored.

Radiation dose to breasts from a cardiac computed tomography angiographyscanogram can be reduced by switching tube position.

Background/aim: In a computed tomography (CT) examination, scanogram images are used to determine the range of the area to be imaged before scanning. The importance of scanogram image exposure has increased since total examination radiation has decreased due to technological advancements. The purpose of this study was to determine and compare radiation doses delivered to patients while the tube was in anterior-posterior (AP) and posterior-anterior (PA) positions during a CT angiography scanogram.

Once the Light Touch to the Brain: Cytotoxic Effects of Low-Dose Gamma-Ray, Laser Light, and Visible Light on Rat Neuronal Cell Culture.

Objective: We aimed to evaluate the effects of gamma-ray, laser light, and visible light, which neurons are commonly exposed to during treatment of various cranial diseases, on the viability of neurons.

Materials And Methods: Neuronal cell culture was prepared from the frontal cortex of 9 newborn rats. Cultured cells were irradiated with gamma-ray for 1-10 min by (152)Eu, (241)Am, and (132)Ba isotopes, visible light for 1-160 min, and laser light for 0.

Computed Tomography-Based SYNTAX Score: A Case Report.

The SYNTAX score is an angiographic scoring system that is currently used for evaluating the complexity of coronary lesions. Its efficiency in both long-term prognosis and the selection of treatment modalities has been shown in many studies. However, there is little evidence for the use of this scoring system in CT angiography, which has become a part of coronary artery disease practice.

Interrupted Aortic Arch Associated with AP Window and Complex Cardiac Anomalies: Multi Detector Computed Tomography Findings.

Interrupted aortic arch is a rare congenital malformation of the aortic arch defined as a loss of luminal continuity between the ascending and descending portions of the aorta. In a simple interrupted aortic arch, only a ventricular septal defect and patent ductus arteriosus are observed. We present a rare complex form of type A interrupted aorta with an aortopulmonary window, an atrial septal defect, a ventricular septal defect, and a patent ductus arteriosus on multidetector computed tomography (MDCT) imaging.
