LDL Promotes Disorders in β-Cell Cholesterol Metabolism, Implications on Insulin Cellular Communication Mediated by EVs.

Dyslipidemia is described as a hallmark of metabolic syndrome, promoting a stage of metabolic inflammation (metainflammation) that could lead to misbalances in energetic metabolism, contributing to insulin resistance, and modifying intracellular cholesterol pathways and the renin-angiotensin system (RAS) in pancreatic islets. Low-density lipoprotein (LDL) hypercholesterolemia could disrupt the tissue communication between Langerhans β-cells and hepatocytes, wherein extracellular vesicles (EVs) are secreted by β-cells, and exposition to LDL can impair these phenomena. β-cells activate compensatory mechanisms to maintain insulin and metabolic homeostasis; therefore, the work aimed to characterize the impact of LDL on β-cell cholesterol metabolism and the implication on insulin secretion, connected with the regulation of cellular communication mediated by EVs on hepatocytes.

Effect of dietary intervention with a legume-based food product on malondialdehyde levels, HOMA index, and lipid profile.

Introduction: Prevalence of overweight and obesity, a condition that promotes development of chronic degenerative diseases, has increased in Mexico in recent years. Implementation of strategies to increase daily consumption of vegetables, legumes, whole grain cereals, and fruits by the population will result in an adequate intake of soluble fiber, antioxidants, protein of vegetable origin, and vitamins.

Objective: To assess the effect of a commercial food product prepared using 6 legumes on some anthropometric and biochemical parameters in apparently healthy subjects.

[Association of high sensitivity C-reactive protein with diet composition in Mexican school children].

The high-Sensitivity C-Reactive Protein (hs-CRP) is a cardiovascular risk marker. In healthy Mexican children, there islittle evidence that shows any relationship between serum levels of this marker with diet. The objective of this studywas to associate serum levels of hs-CRP with the diet composition in Mexican school children.

[Ultra-sensitive C-reactive protein associated to nutritional status and biochemical profile in Mexican shoolchildren].

Background: C-reactive protein (CRP) is a nonspecific marker of inflammation with low serum levels, which are not usually detectable. In order to assess cardiovascular risk in adults apparently healthy, ultrasensitive methods are used, and the CRP measured through these techniques is known as ultrasensitive C-reactive protein (US-CRP). Some researchers report an association of US-CRP with some anthropometric parameters in children with no apparent disease.
