Endoluminal reconstruction with flow-diverting stents represents a widely accepted technique for the treatment of complex intracranial aneurysms. This European registry study analyzed initial experience 15 neurovascular centers Flow-Redirection Intraluminal Device (FRED) system.Consecutive patients aneurysms treated FRED between February 2012 and March 2015 were retrospectively reviewed. Complications adverse events, transient permanent morbidity, mortality, occlusion rates evaluated.During...
Measuring cerebral oxygenation using near-infrared spectroscopy (NIRS) has taken on an increasingly important role in the field of neonatology. Several companies have already developed commercial devices, and more publications are reporting absolute boundary values or percentiles for neonates. We compared four commercially used devices to discover whether they provided consistent results same patients.We recruited nine preterm infants tested them 2 h, sensors from two different devices. The...
Body growth is typically thought to be indeterminate in ectothermic vertebrates. Indeed, until recently, this pattern was considered ubiquitous ectotherms. Our recent observations of a complete plate cartilage (GPC) resorption, reliable indicator arrested skeletal growth, many species lizards clearly reject the ubiquity reptiles and raise question about ancestral state pattern. Using X-ray micro-computed tomography (µCT), here we examined GPCs long bones three basally branching clades...
A method for accurate dimensional and angular measurements of microstructures analysed in the scanning electron microscope is described. The considers central parallel projections involves (a) digital image acquisition stereopaired images from microscope's photodisplay, (b) generation 3D-image representations, (c) setting measuring points digitized images, (d) computation exact space coordinates (x/y/z) corresponding point (xL/yL; xR/yR), (e) determination distances angles between...
Abstract The vasa vasorum of skeletonized and nonskeletonized segments five human great saphenous veins (GSVs), harvested during coronary bypass grafting, were cannulated, rinsed, injected (casted) with the polymerizing resin Mercox‐Cl‐2B. After removal dry vascular tissue, casts examined using scanning electron microscopy. Stereopaired images (tilt angle, 6°) taken, imported into a 3D morphometry system, architecture (arterial venous as well capillaries) was studied qualitatively...
<i>Objective:</i> The detailed spatial arrangement of the vasa vasorum (VV) human great saphenous vein (HGSV) was demonstrated in qualitative and quantitative terms. <i>Materials Methods:</i> Segments HGSV taken from cadavers 12–24 h post mortem patients undergoing aortocoronary bypassing were studied by light microscopy India-ink-injected specimens scanning electron vascular corrosion casts. <i>Results:</i> Arterial feeders found to approach nearby...
The microvascular bed of the stomach Xenopus laevis and changes it undergoes when herbivorous tadpole becomes a carnivorous adult were studied by scanning electron microscopy vascular corrosion casts light stained tissue sections. In tadpoles an upper lower gastric artery supplied, upper, middle medial lateral veins drained vertically extending stomach. During metamorphosis, gained horizontal cranio-caudal extension vessels accordingly become dorsal ventral arteries, anterior, posterior...
Abstract In the present study we compared measurements of vessel lengths from (a) single‐digital scanning electron microscope (SEM) images microvascular corrosion casts (VCCs) gill filters tadpoles Xenopus laevis Daudin by two‐dimensional (2‐D) morphometry (Optimas 6.5, Optimas Corp., Bothell, Wash., USA; planar measurements) and (b) digital stereopairs three‐dimensional (3‐D) (3D‐Morphometry, Minnich Muska OEG, Salzburg). Depending on spatial orientation vessels measured, found a maximum...
Background: The question whether the primary increase of vasa vasorum (VV) venous wall (i) plays an initial role in varicogenesis or (ii) is expression impairment nutritional conditions superficial veins lower extremities not unambiguously solved yet. aim study was to describe arrangement VV within human great saphenous vein (GSV) qualitatively, and its tributaries at different stages varicosis other pathological states like thrombophlebitis phlebosclerosis. Material methods: 22 patients...
Cartilage injuries remain challenging since the regenerative capacity of cartilage is extremely low. The aim was to design a novel type bioactive glass (BG) scaffold with suitable topology that allows formation cartilage-specific extracellular matrix (ECM) after colonization chondrogenic cells for repair. Highly porous scaffolds interconnecting pores consisting 100 % BG were manufactured using melting, milling, sintering and leaching technique. Scaffolds colonized porcine articular...
The vasa vasorum (VV) of explanted segments the human great saphenous vein (Vena saphena magna; HGSV), harvested during dissection for coronary bypass grafts or diseased from "Salzburger Landesklinikum," were studied by scanning electron microscopy and three-dimensional morphometry microvascular corrosion casts. main objective this study was to examine VV's structural arrangement in order find most vital HGSV turn improve results surgeries. presents a meticulous analysis whole system VV its...
The microvascular anatomy of the non-lobulated liver adult Xenopus laevis was studied by scanning electron microscopy vascular corrosion casts. Hepatic portal veins and hepatic arteries entered lobes at hiluses, left these sites. Intraparenchymal, branched up to 10 times before terminal venules supplied sinusoids. closely followed vessels. Arteriolar side branches formed anastomoses with close (arteriolar-portal anastomoses; APAs), sinusoids (arteriolar-sinusoidal ASAs), peribiliary plexus...
Regeneration of articular cartilage remains challenging. The aim this study was to increase the stability pure bioactive glass (BG) scaffolds by means solvent phase polymer infiltration and maintain cell adherence on struts. Therefore, BG either or enhanced with three different amounts poly(D-L-lactide-co-glycolide) (PLGA) were characterized in detail. Scaffolds seeded primary porcine chondrocytes (pACs) human mesenchymal stem cells (hMSCs) a dynamic long-term culture (35 days). Light...
Abstract To demonstrate the 3D microvascular anatomy of brain model organism Xenopus laevis Daudin scanning electron microscopy vascular corrosion casts was correlated with light stained 7 µm thick serial tissues sections. Results showed that supplying arteries descended from leptomeningeal surface without remarkable branchings straight to subventricular zone where they branched and capillarized. Capillaries few H‐ and/or Y‐shaped anastomoses during their centrifugal course toward drained...
Abstract We studied the opisthonephric (mesonephric) kidneys of adult male and female Xenopus laevis using scanning electron microscopy (SEM) vascular corrosion casts light paraplast embedded tissue sections. Both techniques displayed glomeruli from ventral to mid‐dorsal regions with single located dorsally close beneath renal capsule. Glomeruli in general were fed by a afferent arteriole drained via thinner efferent into peritubular vessels. Light SEM revealed sphincters at origins...
