Influence of Lipid Heterogeneity and Phase Behavior on Phospholipase A2 Action at the Single Molecule Level [PDF]
Biophys. J. 2010, 98: 1873-1882, 2009 We monitored the action of phospholipase A2 (PLA2) on L- and D-dipalmitoylphosphatidylcholine (DPPC) Langmuir monolayers by mounting a Langmuir-trough on a wide-field fluorescence microscope with single molecule sensitivity. This made it possible to directly visualize the activity and diffusion behavior of single PLA2 molecules in a heterogeneous ...

The Phospholipases A of Epidermis
Journal of Investigative Dermatology, 1980 Phospholipases A have been characterized in fetal rat epidermis. Both a calcium dependent phospholipase A with pH optimum of 8.5 and a calcium independent enzyme with a pH optimum of 4.5 were found. Activity against both acyl groups of phosphatidyl choline were found for both enzymes and the findings suggested that the acid enzyme (pH 4.5) is primarily

Detection of virulence factors and beta-lactamase encoding genes among the clinical isolates of Pseudomonas aeruginosa [PDF]
International Journal of Pharmaceutical Research, 2019, 2019 Background: Pseudomonas aeruginosa has emerged as a significant opportunistic bacterial pathogen that causes nosocomial infections in healthcare settings resulting in treatment failure throughout the world. This study was carried out to compare the relatedness between virulence characteristics and \b{eta}-lactamase encoding genes producing Pseudomonas ...

Journal of Fungi, 2019 Neutrophils activated with pathogens or their products induce formation of extracellular traps (NETs), but if this constitutes a general response against all pathogenic species in a single genus or intrageneric differences exist remains unknown, yet this

Nuclear Inositides and Inositide-Dependent Signaling Pathways in Myelodysplastic Syndromes
Cells, 2020 Myelodysplastic syndromes (MDS) are a heterogeneous group of hematological malignancies characterized by peripheral blood cytopenia and abnormal myeloproliferation, as well as a variable risk of evolution into acute myeloid leukemia (AML). The nucleus is

Food Science &Nutrition, Volume 11, Issue 1, Page 569-577, January 2023., 2023 The present study suggests that the intake of total phytosterols (PSs), stigmasterol, ß‐sitosterol, ß‐sitostanol and campestanol were inversely associated with the prevalence of obesity. In addition, lower obesity risk for total PSs and PSs subgroups differed for the gender. These results deserve to be further verified in cohort studies.

Phospholipases in Gliomas: Current Knowledge and Future Perspectives from Bench to Bedside
Biomolecules, 2023 Phospholipases are essential intermediaries that work as hydrolyzing enzymes of phospholipids (PLs), which represent the most abundant species contributing to the biological membranes of nervous cells of the healthy human brain.
