The isolation of subfractions of cell membranes on the basis of their solubility in non-ionic detergents has led to the discovery of lipid domain structure in membranes. Detergents used for this purpose include Triton, Brij, Lubrol and CHAPS. Different lipid constituents are known to resist solubilization by different detergents and the resulting fractions may associate with different membrane proteins. In general, the detergent-resistant membrane fractions tend to be dominated by saturated molecular species of sphingomyelin and phosphatidylcholine and invariably include significant proportions of cholesterol. The lipid composition is consistent with formation of liquid-ordered phases. The present evidence favours a model in which the lateral segregation of membrane proteins takes place on the basis of their affinity for liquid-ordered lipid domains within the membrane.

Metabolic syndrome (MS) has a high prevalence, with an estimated one-quarter of the world population affected by this pathological condition. Among the diseases of this syndrome are dysregulation of lipids, hypertension, and insulin resistance. Unfortunately, available drugs in the market used for treating MS, as almost 75% of all drugs, are highly insoluble, presenting a significant demand for strategies to increase their solubility.

The extraction of plant essential oils (EOs) and analysis by gas chromatography coupled to mass spectrometry (GC-MS) are standard methods when studying aromatic plants and the chemical composition of EOs. Here, two simple methods for the extraction of EO compounds from leaves of Thymus vulgaris are described. Organic solvent extraction and solid-phase microextraction (SPME), respectively, are used and the results of the GC-MS analyses are compared.

Small-molecule pectin (SMP) extracted from the leaves of Premna ligustroides Hemsl, with a molecular weight range of 5000-35,000 Da, has demonstrated anti-inflammatory and lipid-lowering properties in vitro. This study explored the effects of SMP on hypercholesterolemia in mice, with a focus on inflammation, lipid profiles, and cholesterol metabolism. Mice received SMP at doses of 607, 303, and 152 mg/kg body weight.

The study emphasises how ubiquitous persistent organic pollutants (POPs) are and how terrible they are for the environment, specifically because of their tendency to build up in living things and cause a variety of health problems, including diabetes, obesity, and cardiovascular disorders. Due to POPs affinity for lipid-rich tissues, they accumulate in a variety of organs, where they cause metabolic disruption and initiate various anabolic pathways. Studies that use fish as a model organism clarify the metabolic effects of POPs, demonstrating non-adipose lipid accumulation and abnormal glucose homeostasis.
