Anatomical and morphometric features of the profunda brachii artery.

When the literature is examined, studies evaluating the profunda brachii artery (PBA) are limited as most studies only investigate the artery's origin. In 44 upper extremities belonging to 24 human anatomical specimens, single and double PBAs were observed in 39 and five cases, respectively. In cases with a single PBA, the origin was the brachial artery (BA) in 35 cases and the posterior circumflex humeral artery in four cases.

Morphometric and anatomic characteristics of pronator quadratus muscle.

Purpose: In surgical procedures commonly employed for the management of scaphoid and distal radial fractures, the incision and dissection of the pronator quadratus muscle play a pivotal role. Nevertheless, comprehensive investigations into the anatomical intricacies of the pronator quadratus muscle have been relatively scarce within the clinical community. In light of this, our study endeavors to make a substantive contribution to the medical literature by conducting a meticulous examination of the morphology and morphometry of this muscle.

Results of combat medic junctional tourniquet training: a prospective, single-blind, randomized, cross-over study.

Background: Bleeding remains the leading cause of potentially preventable deaths both in military and civilian pre-hospital trauma settings. Conventional extremity tourniquets do not control bleeding if an iliac artery or a common femoral artery is injured. Stopping junctional bleeding is particularly challenging and requires the use of specifically designed junctional tourniquets.

Evaluation of possible cytotoxic, genotoxic and epigenotoxic effects of titanium dioxide nanoparticles and possible protective effect of melatonin.

Nanoparticles (NPs) are particles of matter that are between 1 to 100 nm in diameter. They are suggested to cause toxic effects in both humans and environment thorough different mechanisms. However, their toxicity profile may be different from the parent material.

Evaluation of oxidative stress cycle in healthy and inflamed dental pulp tissue: a laboratory investigation.

Objectives: The purpose of this study was to investigate the oxidative stress cycle consisting of reactive oxygen molecules (ROS), glutathione (GSH) and glutathione S-transferase (GST) in caries-related pulp inflammation.

Methodology: Fifty-four pulp tissue samples were collected from healthy donors with the diagnosis of reversible pulpitis, symptomatic irreversible pulpitis, and healthy pulp. Twelve pulp samples from each group were homogenized and total protein, ROS, GSH, and GST were measured by spectrophotometer.
