The study was conducted on 10 pairs of eye balls to study the histomorphological structures of the vascular tunics of eye ball. The vascular layer includes the choroid, ciliary body and iris. The choroid was composed of four layers such as (i) Suprachoroid (ii) Large vessel layer (iii) Tapetum and (iv) Choriocapillary layer. The mean thickness of choroid at the center of the tunic was 76.55±3.7...

Objective To evaluate the inter-rater reliability of semiautomated segmentation of spectral domain optical coherence tomography (OCT) macular volume scans. Methods Macular OCT volume scans of left eyes from 17 subjects (8 patients with MS and 9 healthy controls) were automatically segmented by Heidelberg Eye Explorer (v1.9.3.0) beta-software (Spectralis Viewing Module v6.0.0.7), followed by m...

abstract background: for treatment verification in radiation therapy. several physical characteristics of scanningliquid filled ionization chamber epid (slic-epid) including: extra build-up layer,reproducibility and uniformity, and noise level were investigated.electronic portal imaging devices (epids) have found an outstanding positionmaterials and methods: equilibrium, 1-30 mm white water mat...

The turnover of free cholesterol in atheromatous plaque lipid phases was studied in a patient undergoing peripheral vascular surgery. [14C]Cholesterol was injected intravenously 139 days prior to surgery, and [3H]cholesterol was injected 12 days pre-op. The plasma cholesterol specific radioactivity decay curves were determined from the times of isotope injection until surgery. At surgery, ather...

Virtual distillation is an error-mitigation technique that reduces quantum-computation errors without assuming the noise type. In scenarios where user of a quantum circuit required to additionally employ peripherals, such as delay lines, introduce excess noise, we find performance can be improved if peripheral, whenever possible, split across entire circuit, is, when channel uniformly distribut...

the objective of this study was to describe the role of electrical stimulation in controlling peripheral vertigo. in a prospective study on 13 healthy volunteers, nystagmus was induced with caloric stimulation and the interval of nystagmus disappearance was recorded. this time indicates the basal response of vestibular end-organ. after caloric irrigation, pulsed signal was applied for each pers...

introduction: multiple sclerosis (ms) is generally known as a manageable but not yet curable autoimmune disease affecting central nervous system. a potential therapeutic approach should possess several properties: prevent immune system from damaging the brain and spinal cord, promote differentiation of oligodendrocyte progenitor cells (opcs) into mature oligodendrocytes to produce myelin, preve...

background: human peripheral blood nk cells constitutively express cd56 and cd16 antigens. peripheral blood nk cells seem to be strongly related with decidual nk cells, and may reflect the decidual nk cell functional status. there are varied reports concerning the relationship between nk cell cytotoxicity in women with recurrent spontaneous abortion. objective: to study nk activity in women wit...

objective: stevioside is a natural non-caloric sweetener which has been reported to have anti-inflammatory activity.  the aim of  the present study was to examine in vitro and in vivo effects of  stevioside on rats  plasma levels of tumor necrosis factor- α (tnf-α),  interleukin-1β (il-1β), tnf-α and il-1β release from lipopolysaccharide(lps)-stimulated rat peripheral blood mononuclear cells (p...

conclusion in cases with critical atherosclerotic disease of anterior tibial artery, pta-based biphasic or triphasic retrograde collateral flow prevents ischemia, whereas monophasic support or no retrograde flow remains incapable. results in the patient group, 31 lower limb arteries, of total of 17 cases, were included. after compression maneuver, dpa in 11 cases (six right, five left) showed r...
