BACKGROUND There is limited data in the literature related to the microanatomic features of the perforating branches of the vertebral artery. METHODS The 44 vertebral arteries and their branches were injected with india ink or a radiopaque substance and examined under the stereoscopic microscope. RESULTS The perforating arteries were noted to range in(More)
The perforating vessels supply very important regions of the brain stem and diencephalon, as well as the basal ganglia and internal capsule. Some of their micro-anatomical characteristics are still not well known. The aim of this study was to examine and evaluate the features of all the perforating vessels. The arteries of 24–32 cerebral hemispheres,(More)
The lenticulostriate arteries (LSA) and their microanatomy, region of supply and atherosclerosis were examined in 24 microdissected brains, arterial casts, and histological specimens. The LSA ranged from 2 to 12 in number and from 0.10 mm to 1.28 mm in diameter. They always arose from the initial segment of the middle cerebral artery (MCA), often from the(More)
Although the general vascular supply of the basal ganglia and internal capsule is well known, precise data are lacking regarding the variations of the vascular territories in the two regions. Twelve hemispheres were studied following an injection of coloured ink into the main cerebral arteries, namely the anterior cerebral (ACA), middle cerebral (MCA),(More)
Short title: Ryanodine receptors, voltage-gated calcium channels and PKA Abstract We present the review of the data from the literature about relationship between ryanodine receptors and voltage-gated calcium channels in myocardium, and also how both of them are related to protein kinase A. Ryanodine receptors, which have three subtypes (RyR1-3), are(More)
INTRODUCTION Determining the center of tibial insertion of the anterior cruciate ligament is important during reconstruction ligament. AIM Determining the center of insertion of the anterior cruciate ligament on the anterior intercondylar area relate to anterior and medial edge of the upper end of tibia. MATERIAL AND METHODS The messurement has been(More)
OBJECTIVE Intraventricular surgery requires a detailed knowledge of the microanatomy of the choroid plexus vasculature. METHODS Twenty choroid plexuses were microdissected, and two additional plexuses were prepared for microscopic examination. RESULTS The choroid plexus was perfused primarily by the anterior choroidal artery (AChA) and the lateral(More)
We present a review about the relationship between ryanodine receptors and voltage-gated calcium channels in myocardium, and also how both of them are related to protein kinase A. Ryanodine receptors, which have three subtypes (RyR1-3), are located on the membrane of sarcoplasmic reticulum. Different subtypes of voltage-gated calcium channels interact with(More)
The purpose of this study was to determine the difference in the concentrations of testosterone, 17-β estradiol and progesterone between female patients with and without ACL rupture and the possible effect of these hormones on generalised joint laxity. Female subjects with non-contact knee joint injury were included in this study. They were divided into two(More)
The purpose of this study is to determine the difference in the concentrations of testosterone, 17-β estradiol and progesterone between male patients with and without ACL rupture, as well as the possible effect of these hormones on generalized joint laxity. Male subjects with non-contact knee joint injury were included in this study. Two groups were formed:(More)
