Purpose: It has been demonstrated that the coronary artery anomalies (CAAs) are generally asymptomatic. However, some cases can cause severe life threatening events. As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative to invasive coronary angiography for the evaluation of coronary anatomy, the prevalence of CAAs in CCTA may more closely reflect the true prevalence in the general population.

Purpose: The main objective of the study was to evaluate the probable diversity in the area of the foramen magnum (FM) calculated by different measuring methods.

Methods: The study was conducted on 24 dry skulls, present in the collection of the Anatomy Department, Faculty of Medicine, Mersin University. The area of FM was calculated by different measurement methods including automatic field setting, Teixeria and Radinsky formulas obtained from anatomic (ASM), photographic (PSM) and radiologic (RSM) skull measurements.

In this study, we evaluated the effects of trapidil on crush injury by monitoring nitric oxide, malondialdehyde and transforming growth factor-Beta2 levels and by transmission electron microscopy in the rat sciatic nerve. The sciatic nerve was compressed for 20 sec by using a jewelers forceps. Trapidil treatment groups were administrated a single dose of trapidil (8 mg/kg) intraperitoneally just after the injury.

We observed a bilateral and symmetrical variation of the anterior belly of the digastric muscle during the dissection of a 35-year-old female cadaver. The accessory muscle bundles were arranged in a cross. These bundles were found superficial to the mylohyoid muscle and deep in the platysma.
