AIM To investigate the potential advantage of an enhanced corneal compensation algorithm (ECC) compared with variable corneal compensation (VCC) in the analysis of scanning laser polarimetric (SLP) images with atypical retardation pattern (ARP). METHODS SLP-VCC images with ARP (typical scan score (TSS) <80) of one eye of each of 27 glaucoma patients and 19 healthy subjects were compared with ...

Chain code is fundamental for many applications in image analysis and pattern recognition, because it reduces the amount of stored data and preserves the maintenance of data. The most famous chain code which applied in many applications is Freeman chain code. One of the other kinds of chain code is the Vertex Chain Code (VCC).The VCC proposed by Bribiesca and it has some preferences such as sta...

HIV-1 particles assemble and bud from the plasma membrane of infected T lymphocytes. Infected macrophages, in contrast, accumulate particles within an apparent intracellular compartment known as the virus-containing compartment or VCC. Many aspects of the formation and function of the VCC remain unclear. Here we demonstrate that VCC formation does not actually require infection of the macrophag...

OBJECTIVE To evaluate the changes over two years in the retinal nerve fibre layer (RNFL) of patients with multiple sclerosis (MS). To compare the ability of optical coherence tomography (OCT), scanning laser polarimetry (GDx), visual evoked potentials (VEP) and visual field examination to detect axonal loss in these patients. MATERIAL AND METHODS Fifty eyes of MS patients without episodes or ...

PURPOSE To apply Fourier analysis to the retinal nerve fiber layer (RNFL) thickness measurements obtained with scanning laser polarimetry (SLP), by using variable corneal compensation, and to evaluate the ability of this method to discriminate glaucomatous from normal eyes. METHODS The study included one eye each of 55 patients with glaucoma and 52 healthy subjects. RNFL thickness measurement...

PURPOSE To establish a database of scanning laser polarimetry (GDx) parameters for children between 6 and 9 years of age and compare the results at each age. METHODS The retinal nerve layer thickness of 116 children from one school was evaluated with GDx and the results were analyzed for each age and for the entire group to determinate the normal range for that population. RESULTS In the gl...

The change of steroid levels may also exert different modulatory effects on the number and class of serotonin receptors present in the plasma membrane. The effects of chronic treatment of testosterone for anxiety were examined and expression of 5-HT2A serotonergic receptor, neuron, astrocyte, and dark neuron density in the hippocampus of gonadectomized male mice was determined. Thirty-six adult...

We conducted two studies to determine the effect of gender, gonadectomy (GDX) on growth and plasma cholesterol levels in pigs. In experiment 1, five sham-operated and five GDX female Landrace pigs (26 kg) were allowed to have free access to water and feed up to market weight (approximately 100 kg). Body weight and feed consumption were recorded biweekly, and daily body weight gain, daily feed i...

The theory and first implementation of a vibrational coupled cluster (VCC) method for calculations of the vibrational structure of molecules is presented. Different methods for introducing approximate VCC methods are discussed including truncation according to a maximum number of simultaneous mode excitations as well as an interaction space order concept is introduced. The theory is tested on c...

The maternal dorsal determinants required for the specification of the dorsal territories of Xenopus early gastrulae are located at the vegetal pole of unfertilised eggs and are moved towards the prospective dorsal region of the fertilised egg during cortical rotation. While the molecular identity of the determinants is unknown, there are dorsal factors in the vegetal cortical cytoplasm (VCC). ...
