AIM Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) has been suggested as an independent predictor of cardiovascular events in epidemiological studies. We sought to evaluate Lp-PLA(2) as a risk factor for future cardiovascular events in patients with acute coronary syndromes (ACS) and to elucidate the relationship between Lp-PLA(2) and other known risk markers in ACS patients and healthy ...

Microwave irradiation was used to synthesize PEG-PCL and PEG-PLA copolymers that are composed of biodegradable polymers including PEG, PLA, and PCL. These copolymers were used for loading docetaxel in nanoparticles. Single emulsion-solvent evaporation technique was applied for preparing the PEG-PLA and PEG-PCL mixed nanoparticles (micelles and polymersomes) with different proportions, including...

The phospholipase A(2) (PLA(2)) superfamily consists of a broad range of enzymes defined by their ability to catalyze the hydrolysis of the middle (sn-2) ester bond of substrate phospholipids. The hydrolysis products of this reaction, free fatty acid and lysophospholipid, have many important downstream roles, and are derived from the activity of a diverse and growing superfamily of PLA(2) enzym...

BACKGROUND With additive manufacturing (AM) individual and biocompatible implants can be generated by using suitable materials. The aim of this study was to investigate the biological effects of polylactic acid (PLA) manufactured by Fused Deposition Modeling (FDM) on osteoblasts in vitro according to European Norm / International Organization for Standardization 10,993-5. METHOD Human osteobl...

The superlative mechanical properties of graphene-based materials make them the ideal filler materials for polymer composites reinforcement. Two types of graphene-based materials, graphene nanoplatelets (xGnP) and reduced graphene oxide (rGO), were used as nanofiller in poly(lactic acid) (PLA) polymer matrix, as well as plasticized PLA. The addition of rGO into PLA or plasticized PLA substantia...

A thorough investigation of the mode of action of Aspergillus niger (4M-147) pectin lyase A (PLA) on differently C(6)-substituted oligogalacturonides is described. PLA appeared to be very specific for fully methyl-esterified oligogalacturonides: removal of the methyl-ester or changing the type of ester (ethyl esterification) or transamidation resulted in (almost) complete loss of conversion. Th...

Pyogenic liver abscess (PLA) is a potentially life-threatening disease affecting many parts of the world, especially Asia. In this study, we explored the clinical and microbiological characteristics of PLA in Chinese patients.A 5-year (2010-2014) retrospective review of medical records on all PLA patients who were admitted to a tertiary teaching hospital was performed.Among 217 PLA cases who we...

Phospholipase A(2) (PLA(2)) hydrolyzes phospholipids at the sn-2 position to yield lysophospholipids and free fatty acids. Of the four paralogs expressed in Arabidopsis, the cellular functions of PLA(2)α in planta are poorly understood. The present study shows that PLA(2)α possesses unique characteristics in terms of spatiotemporal subcellular localization, as compared with the other paralogs t...
