The formation of lateral microdomains is emerging as a central organizing principle in bacterial membranes. These microdomains are targets of antibiotic development and have the potential to enhance natural product synthesis, but the rules governing their assembly are unclear. Previous studies have suggested that microdomain formation is promoted by lipid phase separation, particularly by cardiolipin (CL) and isoprenoid lipids, and there is strong evidence that CL biosynthesis is required for recruitment of membrane proteins to cell poles and division sites. New work demonstrates that additional bacterial lipids may mediate membrane protein localization and function, opening the field for mechanistic evaluation of lipid-driven membrane organization in vivo.

Microwave-assisted extraction conditions were optimized using response surface methodology to evaluate the effects of extraction parameters on the yield and carbohydrate content of Luffa aegyptiaca mucilage. Extraction at 540 W for 2 min with a 1:20 (g/mL) was determined as the optimal parameter, resulting in a maximum yield of 5.90 % (w/w) with 63 % carbohydrate content consisting of glucose, galactose, maltose, mannose, and galacturonic acid, with structural linkages of β (1 → 4) and β (1 → 6) glycosidic bonds.

Collared Peccary (Pecari tajacu, Linnaeus, 1758) is a mammalian Tayassuidae species from tropical to semi-arid areas. The morphological features of the oral cavity in this species were identified and described. Tonsils are secondary lymphoid organs essential for contact with antigens due to food and air intake.

Pancreatic ductal adenocarcinoma (PDAC) is one of the worst solid malignancies in regard to outcomes and metabolic dysfunction leading to cachexia. It is alarming that PDAC incidence rates continue to increase and warrant the need for innovative approaches to combat this disease. Due to its relatively slow progression (10-20 years), prevention strategies represent an effective means to improve outcomes.

Group V Chitin Deacetylases Are Responsible for the Structure and Barrier Function of the Gut Peritrophic Matrix in the Chinese Oak Silkworm .

Chitin deacetylases (CDAs) are carbohydrate esterases associated with chitin metabolism and the conversion of chitin into chitosan. Studies have demonstrated that chitin deacetylation is essential for chitin organization and compactness and therefore influences the mechanical and permeability properties of chitinous structures, such as the peritrophic membrane (PM) and cuticle. In the present study, two genes ( and ) encoding CDA protein isoforms were identified and characterized in Chinese oak silkworm () larvae.

An Overview of the Current State of Cell Viability Assessment Methods Using OECD Classification.

Int J Mol Sci

December 2024

Faculty of Medicine, Institute of Translational and Clinical Research, University of Maribor, Taborska ulica 8, 2000 Maribor, Slovenia.

Over the past century, numerous methods for assessing cell viability have been developed, and there are many different ways to categorize these methods accordingly. We have chosen to use the Organisation for Economic Co-operation and Development (OECD) classification due to its regulatory importance. The OECD categorizes these methods into four groups: non-invasive cell structure damage, invasive cell structure damage, cell growth, and cellular metabolism.
