A novel method for comparison of arterial remodeling in hypertension: Quantification of arterial trees and recognition of remodeling patterns on histological sections

Remodeling of spatially heterogeneous arterial trees is routinely quantified on tissue sections by averaging linear dimensions, with lack of comparison between different organs and models. The impact of experimental models or hypertension treatment modalities on organ-specific vascular remodeling remains undefined. A wide variety of arterial remodeling types has been demonstrated for hypertensive models, which include differences across organs. The purpose of this study was to reassess methods for measurement of arterial remodeling and to establish a morphometric algorithm for standard and comparable quantification of vascular remodeling in hypertension in different vascular beds. We performed a novel and comprehensive morphometric analysis of terminal arteries in the brain, heart, lung, liver, kidney, spleen, stomach, intestine, skin, skeletal muscle, and adrenal glands of control and Goldblatt hypertensive rats on routinely processed tissue sections. Mean dimensions were highly variable but grouping them into sequential 5 μm intervals permitted creation of reliable linear regression equations and complex profiles. Averaged arterial dimensions demonstrated seven remodeling patterns that were distinct from conventional inward-outward and hypertrophic-eutrophic definitions. Numerical modeling predicted at least nineteen variants of arterial spatial conformations. Recognition of remodeling variants was not possible using averaged dimensions, their ratios, or the remodeling and growth indices. To distinguish remodeling patterns, a three dimensional modeling was established and tested. The proposed algorithm permits quantitative analysis of arterial remodeling in different organs and may be applicable for comparative studies between animal hypertensive models and human hypertension. Arterial wall tapering is the most important factor to consider in arterial morphometry, while perfusion fixation with vessel relaxation is not necessary. Terminal arteries in organs undergo the same remodeling pattern in Goldblatt rats, except for organs with hemodynamics affected by the arterial clip. The existing remodeling nomenclature should be replaced by a numerical classification applicable to any type of arterial remodeling

Analysis of Microcrafters in Materials Specimens after Long-Term Exposure on ISS Surface

The "Komplast" experiment has been carried out on the ISS by the Khrunichev Space Center jointly with other Russian scientific centers since 1998. The experiment incorporates the "Komplast" cartridges on the FGB exterior, which are fitted with materials specimens and sensors. The cartridges were sent into orbit together with FGB on 20 November 1998. In March 2011, two of the cartridges were taken back from the ISS by the "Discovery" American space shuttle after being exposed in the open space for 12 years. In the framework of this experiment the subject of analysis is the effect of the space environment on the exposed specimens of various materials. This report covers the analysis results of the surface morphology of various materials taken from the "Komplast" cartridges exposed to hits of micrometeors and micronic particles of space debris. Analysis is made of microcraters of 5 to 250 mcm in specimens of polished metals and silicone comprised in the sensor for micrometeoric particles. The report represents optic and scanning electron microscope images of craters formed in the specimens by high-velocity and low-velocity particles impacting the surface. By virtue of the electronic microscope, data on composition of the substance in the craters and of the substance of the low-velocity particles are obtained. The data make it possible to differentiate the particles as the natural-origin particles or anthropogenic-origin space debris particles. Distribution of craters and low-velocity particles in the size range of 5 to 50 mcm is obtained. The data are compared with the existing models of fluxes of natural-origin and artificial-origin microparticles on the ISS orbit. Inhomogeneous particles of complicated configuration are discovered on the surface of the analyzed specimens, whose origin are not uniquely determined and are to be the subject of further study

A Study of Micro Craters in Material Samples after Long Duration Exposure on ISS Komplast Panels

The Komplast materials experiment was designed by the Khrunichev State Research and Production Space Center, together with other Russian scientific institutes, and has been carried out by Mission Control Moscow since 1998. Komplast panels fitted with material samples and sensors were located on the International Space Station (ISS) Functional Cargo Block (FGB) module exterior surface. Within the framework of this experiment, the purpose was to study the effect of the low earth orbit (LEO) environment on exposed samples of various materials. The panels were sent into orbit with the FGB when it launched on November 20, 1998.
