Lipoprotein-associated phospholipase A₂ (Lp-PLA₂) is a risk factor of cardiovascular disease. Plasma Lp-PLA₂ is mainly associated with apolipoprotein (apo)B-containing lipoproteins, primarily with low density lipoproteins (LDLs). Importantly, only a proportion of circulating lipoproteins contain Lp-PLA₂. We determined the plasma levels of Lp-PLA₂-bound apoB (apoB/Lp-PLA₂) in patients with prima...

The micromechanical deformation mechanisms of a polylactic acid (PLA)/natural rubber (NR) blend (PLA/NR 90/10 wt%) and its organoclay filled bionanocomposites have been investigated by small and wide angle X-ray scattering (SAXS–WAXS) under tensile conditions. The addition of NR to a PLA matrix changed the brittle fracture of PLA to a ductile deformation through the debonding of the rubber drop...

During the last four decades the biodegradable polymers have found their place in special applications in biomedical and technical fields. [1-4] However, their worldwide production volumes are still marginal compared with non-biodegradable polymers. One of the major restricting factors for the wider use of biodegradable polymers in the field of load bearing medical devices, packaging, and consu...

To investigate the effect of repair of bioabsorbable poly(lactide) (PLA) biliary stent in common bile duct (CBD) transection injury in canine prior to the clinical application. Circular tubing CBD stent was prepared by melt extraction technique using PLA. A transection incision was made on CBD of the normal canine, and then closed the incision with laser welding followed the implantation of PLA...

Cinnamon essential oil (CEO) was successfully encapsulated into chitosan (CS) nanoparticles at different loading amounts (1%, 1.5%, 2%, and 2.5% v/v) using oil-in-water (o/w) emulsion and ionic-gelation methods. In order to form active packaging, poly(lactic acid) (PLA) was used to fabricate PLA/CS-CEO composite fibers using a simple electrospinning method. The shape, size, zeta potential, and ...

Phosphoric acid added L-alanine (PLA) single crystals were grown successfully by slow evaporation technique at room temperature by taking 2:1 molar ratio of L-alanine and phosphoric acid. Solubility and nucleation kinetic measurements were carried out for the PLA sample. Critical nucleation parameters have been calculated. Structural analysis reveals that PLA crystal crystallizes in orthorhombi...

BACKGROUND Phospholipase A (PLA) is an important group of enzymes responsible for phospholipid hydrolysis in lipid signaling. PLAs have been implicated in abiotic stress signaling and developmental events in various plants species. Genome-wide analysis of PLA superfamily has been carried out in dicot plant Arabidopsis. A comprehensive genome-wide analysis of PLAs has not been presented yet in c...

OBJECTIVES The aim of this study was to evaluate the effect of caffeine ingestion on performance and estimated energy system contribution during simulated taekwondo combat and on post-exercise parasympathetic reactivation. METHODS Ten taekwondo athletes completed two experimental sessions separated by at least 48 hours. Athletes consumed a capsule containing either caffeine (5 mg∙kg-1) or pla...
