The essential decrease of the rate of turnover of phosphatidic acids (PA), polyglycerophosphates (PGP) and their lysoderivatives (LPGP), sphinigomyelin (SM) and lysophosphatidylcholine (LPC), phosphatidyletnanolamine (PEA) was found in male mice of BALB/c strain with subacute alloxan diabetes (glucose concentration in the blood was not less than 14 mmol/l) during examination of phospholipid metabolism in the liver by the rate of 3H-acetate and 14C-palmitate incorporation into corresponding chromatographic phospholipid fractions. On the contrary, turnover of phosphatidilcholine (PC) significantly increased. The of main structural phospholipid components of hepatocyte cellular membranes--PEA and PC--were found to be decreased by 41 and 32%, respectively. LPGP and PA levels decreased to a lesser extent. The level of PGP, SM, phosphatidylinositol and LPG did not differ from the control level.

An aerobic, Gram-stain-positive, motile, coccus-shaped actinomycete, designated strain LSe6-4, was isolated from leaves of sea purslane (Sesuvium portulacastrum L.) in Thailand and subjected to a polyphasic taxonomic studies. Growth of the strain occurred at temperatures between 15 and 38 °C, and with NaCl concentrations 0-13%.

The skin is a barrier that protects the human body against environmental factors (physical, including solar radiation, chemicals, and pathogens). The integrity and, consequently, the effective metabolic activity of skin cells is ensured by the cell membrane, the important structural and metabolic elements of which are phospholipids. Phospholipids are subject to continuous transformation, including enzymatic hydrolysis (with the participation of phospholipases A, C, and D) to free polyunsaturated fatty acids (PUFAs), which under the influence of cyclooxygenases (COX1/2), lipoxygenases (LOXs), and cytochrome P450 (CYPs P450) are metabolized to various classes of oxylipins, depending on the type of PUFA being metabolized and the enzyme acting.

Modification of silica interfaces by covalent attachment of functional ligands is a primary means of controlling the interfacial chemistry of porous silicas used in separations, environmental cleanup, and biosensing. Recently, modification of hydrophobic, -alkyl-silane-functionalized interfaces has been achieved through self-assembly of zwitterionic phospholipids or mixed-charged surfactants to form "hybrid bilayers", producing interfaces that mimic lipid-bilayer partitioning and provide shape-selective partitioning of aromatic hydrocarbons. Charged headgroups, however, introduce electrostatic interactions that strongly influence the retention of ionizable solutes and require careful control over pH and ionic strength in the solution phase.

The transdermal route is one of the effective routes for delivering drugs. It also overcomes many limitations associated with oral delivery. One of the limitations of this route is the drug's poor skin permeability-stratum corneum, the skin's outermost layer that also acts as a barrier for the drug to penetrate.

The present study was aimed at revealing the metabolic changes that occurred in the cellular lipid pattern of acute and chronic myeloid leukaemia cells following treatment with cannabidiol (CBD). CBD is a non-psychoactive compound present in Cannabis sativa L., which has shown an antiproliferative action in these type of cancer cells.
