The cholesterol with different concentration in hypercholesterolemia serum was studied by the method of spectroscopy technology. The absorption and fluorescence spectra of normal human serum and hypercholesterolemia serum were obtained respectively; the spectral characteristic of each sample and the difference between two kinds of samples were discussed too. The results indicate that the absorption and fluorescence spectra of hypercholesterolemia serum are different from those of normal human serum. The absorptivity and the fluorescence intensity of hypercholesterolemia serum are both higher than those of normal human serum. Besides, there are new absorptive peaks and new fluorescence peaks in the spectrogram. Thus, the abnormalism of cholesterol in serum can be judged by comparing the absorption and fluorescence spectra. The researches in the present paper provide an experimental foundation for the diagnosis of cholesterol in blood.

Background/purpose: Studies have demonstrated a relation between hypercholesterolemia and development of apical periodontitis (AP), but the underlying mechanism is uncertain. 27-hydroxycholesterol (27HC), produced by cytochrome P450 27A1 (CYP27A1)-catalyzed hydroxylation of cholesterol, is known to possess pro-inflammatory activity. Felodipine is an anti-hypertensive agent able to inhibit CYP27A1.

Low-density lipoprotein cholesterol (LDL-C) is a well-established risk factor for cardiovascular disease, and it plays a causal role in the development of atherosclerosis. Genome-wide association studies (GWASs) have successfully identified hundreds of genetic variants associated with LDL-C. Most of these risk loci fall in non-coding regions of the genome, and it is unclear how these non-coding variants affect circulating lipid levels.

Background: Disorders of glucose and lipid metabolism, such as obesity, diabetes mellitus, or hypercholesterolemia, can cause serious complications, reduce quality of life, and lead to increased premature mortality. Olivetol, a natural compound, could be proposed as a promising therapeutic agent for preventing, treating, or alleviating metabolic complications of such pathological conditions.
Methods: In this study, the researchers conducted a broad parallel investigation of olivetol's effects on metabolic state and gut microbiota functionality in mouse models of alimentary obesity, diabetes mellitus type 1 and 2, and hypercholesterolemia.

Air pollutants directly and indirectly cause vitamin D deficiency (VDD). In addition, smoking increases oxidative stress and accelerates skin aging, thereby reducing the body's vitamin D concentration. Previous study reported that VDD increases total cholesterol concentration by reducing vitamin D receptor activity.

Background And Aims: Familial Hypercholesterolemia (FH) is a monogenic disease that leads to early-onset atherosclerosis. Causative mutations in FH-related genes are found in 60-80 % of patients, while epigenetic factors may contribute to mutation-negative cases. This study analyzed miRNAs and proteins from plasma-derived extracellular vesicles (EVs) of FH patients to explore their contribution in FH diagnosis.
