OBJECTIVES This study sought to examine the role of lipoprotein-associated phospholipase A₂ (Lp-PLA₂/PLA2G7) in human inflammation and coronary atherosclerosis. BACKGROUND Lp-PLA₂ has emerged as a potential therapeutic target in coronary heart disease. Data supporting Lp-PLA₂ are indirect and confounded by species differences; whether Lp-PLA₂ is causal in coronary heart disease remains in que...

BACKGROUND This study aimed to evaluate the applicability of Cobra perilaryngeal airway (Cobra PLA™) for obese patients under general anesthesia and also to compare the results with those of classic laryngeal mask airway (LMA™). MATERIALS AND METHODS Seventy-three overweight and obese patients were included in this study. The patients were randomly assigned to LMA™ or Cobra PLA™ groups. Time ...

A patient monosensitized to plane pollen is described On ISAC 103 the patients showed IgE reactivity to both Pla a 1 and Pla a 2, but on immunoblot analysis the serum showed a single IgE reactivity at about 50 kDa allergen.

Polylactic acid (PLA)/styrene-ethylene-butylene-styrene (SEBS) composites were prepared by melt blending. Differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WXRD) were used to characterize PLA and PLA/SEBS composites in terms of their melting behavior and crystallization. Curves from thermal gravimetric analysis (TGA) illustrated that thermostability increased with SEBS c...

Background. Oxidative stress (OS) contributes to brain reperfusion injury after ischemic stroke. Policosanol, a mixture of 8 higher aliphatic sugarcane wax alcohols, has shown to protect against experimental brain ischemia. Objectives. To investigate the effect of policosanol plus aspirin (AS) therapy on the neurological outcome and plasma oxidative variables in patients post-ischemic stroke Me...

Biodegradable, biocompatible polymers are of interest for use in several biomedical and pharmaceutical applications. Based on its biodegradability, biocompatibility, high mechanical strength, and good shaping and molding properties, polylactide (PLA) is frequently utilized as an implantable carrier for drug delivery systems, as well as a surgical repair material. However, its high crystallinity...

Accurate prediction of cardiac output (CO), left atrial pressure (PLA), and right atrial pressure (PRA) is a prerequisite for management of patients with compromised hemodynamics. In our previous study (Uemura et al. Am J Physiol Heart Circ Physiol 286: H2376-H2385, 2004), we demonstrated a circulatory equilibrium framework, which permits the prediction of CO, PLA, and PRA once the venous retur...

Phospholipase A(2) (PLA(2)) catalyses the hydrolysis of phospholipids into lysophospholipids and free fatty acids. Physiological studies have indicated that PLA(2) is involved in stomatal movement. However, genetic evidence of a role of PLA(2) in guard cell signalling has not yet been reported. To identify PLA(2) gene(s) that is (are) involved in light-induced stomatal opening, stomatal movemen...

Present study shows that non-covalent interaction of kaouthiotoxin (KTX) with their respective pohospholipase A(2) (PLA(2)) from the venom of N. kaouthia displayed marked synergism to exert cytotoxicity without altering the biochemical properties of PLA(2). For example, although NK-PLA(2) or KTX alone did not induce appreciable hemolysis of washed human erythrocytes; however, the hemolytic pote...

Time-resolved fluoroimmunoassays (TR-FIA) were developed for all human secreted phospholipases A(2) (PLA(2)), viz. group (G) IB, GIIA, GIID, GIIE, GIIF, GIII, GV, GX and GXIIA PLA(2) and the GXIIB PLA(2)-like protein. Antibodies were raised in rabbits against recombinant human PLA(2) proteins and used in sandwich-type TR-FIAs as both catching and detecting antibodies, the latter after labeling ...
