AI Article Synopsis
- The study identifies three types of hyperlipoproteinaemia in ponies based on serum lipid and lipoprotein concentrations: Type 1 (high VLDL), Type 2 (high chylomicrons and VLDL), and Type 3 (moderate chylomicrons with high VLDL).
- The classification method relies on electrophoretic patterns of the lipoproteins in serum samples.
- Experiments involving blood transfusions showed different responses in normal ponies; heparin increased chylomicrons and VLDL, while sodium citrate mainly increased VLDL.
Article Abstract
(I) The lipid and lipoprotein concentrations in sera of 4 healthy and 9 hyperlipaemic patients were determined. From the results of the analyses, it is suggested that three types of hyperlipoproteinaemia can be distinguished in ponies: (a) Type 1, characterised by a very pronounced increase in only the very low density lipoproteins (VLDL); (b) Type 2, in which there is a pronounced increase in the chylomicrons (Chylo) and the very low density lipoproteins (VLDL); (c) Type 3, which can be the result of fasting and is characterised by a moderate increase in the concentration of chylomicrons and a greater increase in very low density lipoproteins. It is suggested that hyperlipoproteinaemia in ponies can be classified on the basis of electrophoretic patterns. (II) To gather more information on the metabolism of extra offered lipids, blood from ponies suffering from two different types of hyperlipoproteinaemia was transfused into normal ponies and the changes in lipid and lipoprotein concentrations in the blood serum were followed. The reactions were different. When heparin was used as anticoagulant a great increase in chylomicrons and a significant increase in very low density lipoproteins in a healthy pony was observed. When sodium citrate was used as anticoagulant a clear increase in the VLDL fraction only was noticed.

Background And Objectives: Lipid metabolism in older adults is affected by various factors including biological aging, functional decline, reduced physiologic reserve, and nutrient intake. The dysregulation of lipid metabolism could adversely affect brain health. This study investigated the association between year-to-year intraindividual lipid variability and subsequent risk of cognitive decline and dementia in community-dwelling older adults.

Maintaining human body temperature in both high and low-temperature environments is fundamental to human survival, necessitating high-performance thermal insulation materials to prevent heat exchange with the external environment. Currently, most fibrous thermal insulation materials are characterized by large weight, suboptimal thermal insulation, and inferior mechanical and waterproof performance, thereby limiting their effectiveness in providing thermal protection for the human body. In this study, lightweight, waterproof, mechanically robust, and thermal insulating polyamide-imide (PAI) grooved micro/nanofibrous aerogels were efficiently and directly assembled by electrospinning.

ConspectusZinc metal batteries (ZMBs) appear to be promising candidates to replace lithium-ion batteries owing to their higher safety and lower cost. Moreover, natural reserves of Zn are abundant, being approximately 300 times greater than those of Li. However, there are some typical issues impeding the wide application of ZMBs.

Microcavity exciton polaritons (polaritons) as part-light part-matter quasiparticles garner considerable attention for Bose-Einstein condensation at elevated temperatures. Recently, halide perovskites have emerged as promising room-temperature polaritonic platforms because of their large exciton binding energies and superior optical properties. However, currently, inducing room-temperature nonequilibrium polariton condensation in perovskite microcavities requires optical pulsed excitations with high excitation densities.
