The present study was conducted to determine the recyclability and biodegradability of bamboo fabric-reinforced poly(lactic) acid (BF-PLA) composites for sustainable packaging. BF-PLA composite was recycled through the granulation, extrusion, pelletization and injection processes. Subsequently, mechanical properties (tensile, flexural and impact strength), thermal stability and the morphologica...

The outer membrane plasminogen activator Pla of Yersinia pestis is a central virulence factor in plague. The primary structure of the Pla beta-barrel is conserved in Y. pestis biovars Antiqua, Medievalis, and Orientalis, which are associated with pandemics of plague. The Pla molecule of the ancestral Y. pestis lineages Microtus and Angola carries the single amino acid change T259I located in su...

physical, mechanical and structural properties of poly(lactic acid) (pla)-basedfilms containing different amounts of nanoclay and cellulose prepared bysolvent casting method were examined. physical properties including thickness,transparency and color did not change significantly with addition of nanoparticles to the polymer matrix. x-ray diffraction (xrd) patterns showed that pure pla has a se...

The aim of this large population-based cohort study was to determine whether pyogenic liver abscess (PLA) is associated with the risk of acute kidney injury (AKI).A total of 31,815 patients aged 20 years or older diagnosed with PLA for the first time during hospitalization between 2000 and 2011 were included in a PLA cohort, and 127,620 age- and sex-matched patients without PLA were included in...

BACKGROUND Phospholipase A(2) (PLA(2)) is involved in regulating biosynthesis of arachidonic acid and its metabolites. There are three major structurally different forms of PLA(2): group I, also called pancreatic PLA(2) (PLA(2)-I); group II, referred to as secretory non-pancreatic or synovial or platelet PLA(2) (PLA(2)-II); group IV, referred to as cytosolic PLA(2) (PLA(2)-IV). AIMS To examin...

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...

Compared with pristine polymers, bionanocomposites derived from biopolymers and inorganic nanoparticles have significantly improved electrical/magnetic properties, mechanical properties, thermal stability, gas barrier properties, and fire retardance. In this study, poly(lactic acid) (PLA) nanocomposites were prepared by in situ melt polycondensation of L-lactic acid with different loading ratio...

BACKGROUND The aim of this study was to explore whether there is a relationship between pyogenic liver abscess (PLA) and subsequent risk of acute pancreatitis in Taiwan. METHODS Using inpatients claims data from the Taiwan National Health Insurance Program, we identified 30 866 subjects aged 20-84 years with the first-attack of PLA from 2000 to 2010 as the PLA group and randomly selected 123 ...

We present a dialysis technique to direct the self-assembly of paclitaxel (PTX)-loaded nanoparticles (NPs) using methoxypolyethylene glycol-poly(d,l-lactide) (MPEG-PLA) and PLA, respectively. The composition, morphology, particle size and zeta potential, drug loading content, and drug encapsulation efficiency of both PTX-PLA NPs and PTX-MPEG-PLA NPs were characterized by X-ray diffraction, Four...
