Pilocytic astrocytoma is a rare glioma, seen predominantly in pediatric population and young adults, within first two decades of life. This often located deep midline structures such as brainstem cerebellum. In this tumor occurs supratentorial location. It frequently misdiagnosed mistreated. However, being low-grade with excellent prognosis, if diagnosed correctly, it can be successfully treate...

Molecular dynamics simulations using tight-binding many body potential are carried out to study the roller imprint process of a gold single crystal. The effect of the roller tooth's taper angle, imprint depth, imprint temperature, and imprint direction on the imprint force, adhesion, stress distribution, and strain are investigated. A two-stage roller imprint process was obtained from an imprin...

OBJECTIVE Recently, therapies targeting the biological characteristics of individual cancers according to markers indicating underlying molecular biological mechanisms have become available. Core needle biopsy (CNB) is widely used, not only to diagnose, but also to determine therapeutic strategies, in patients with breast cancer. Although the diagnostic accuracy of CNB is acceptably high, false...

AIM We aimed to investigate the contribution of the touch imprint cytology (TIC) of core needle biopsies (CNBs) to the diagnosis in spinal lesions. MATERIAL AND METHODS Sixty cases with spinal CNB and TIC were included in the study. Hematoxylin and Eosin (H&E) and May-Grunwald- Giemsa (MGG) stained TIC slides and CNB of each case were blindly reevaluated by two pathologists. TIC and CNB findi...
