Studies on the Maturation of Secreted Quorum Sensing Peptides That Regulates S. Aureus Virulence
… Secretion of unique autoinducing peptides (AIPs) and detection of their concentration via AgrC, a transmembrane receptor histidine kinase, coordinates local bacterial population density with global changes in gene expression. In order for S. aureus to produce AIP, three proteolytic …

DIETARY INTERVENTIONS TARGETING GLUCOSE METABOLISM AND HYPERINSULINEMIA: A NEW TRANSLATIONAL PERSPECTIVE FOR THE MANAGEMENT OF ACUTE INTERMITTENT PORPHYRIA
Acute Intermittent Porphyria (AIP) represents the most severe form of hepatic porphyrias, an inherited disorder caused by genetic mutations in the hydroxymethylbilane synthase (HMBS) gene, encoding the porphobilinogen deaminase (PBGD) enzyme and reducing hepatic heme availability. In stressful …

Action identification in chronic pain: how do people construct meaning in action?
… A measure of action identification for pain (AIP) was developed. The AIP was psychometrically evaluated in samples of students. It was administered to 47 chronic pain patients using a forced choice card-sort method. The chronic pain sample also completed the Meaningful Life Measure and …

The Atom Surface Site Interaction Point Approach to Non-Covalent Interactions
… develop the Atom Surface Site Interaction Point (AIP) approach to quantify all non-covalent interactions (NCIs) a molecule is capable of making with the environment, including solvent or any other binding partner in the liquid phase. The approach consists of an AIP description of molecules and a …

Reconstitution and Mechanistic Studies on the Staphylococcal agr Quorum Sensing Circuit
… This bacterium secretes an auto-inducer peptide (AIP), a small, cyclic peptide containing a thiolactone linkage as an indicator of its population density, and up-regulates virulence gene expression in response to high extracellular AIP levels. We have investigated two key biochemical events in S. …

Remodelling Surface Site Interaction Points
… The Atomic Surface Site Interaction Point (AIP) model has been developed to obtain interaction points on these three surfaces using empirical rules for different atom types. This new approach to obtain interaction sites ensures a correct description of secondary electrostatic interactions, …

IPRAMA: INDUCED POLARIZATION FOR RAW MATERIALS
… focuses on the Airborne Induced Polarization (AIP) method. Electromagnetic (EM) methods—both airborne (AEM) and ground-based—are known to be sensitive to induced polarization (IP) effects when surveying chargeable grounds. Although the relevance of IP phenomena in EM data has been demonstrated …
