The Rickettsia prowazekii ExoU homologue possesses phospholipase A1 (PLA1), PLA2, and lyso-PLA2 activities and can function in the absence of any eukaryotic cofactors in vitro.
Here we have characterized the Rickettsia prowazekii RP534 protein, a homologue of the Pseudomonas aeruginosa ExoU phospholipase A (PLA) secreted cytotoxin. Our studies showed that purified recombinant RP534 PLA possessed the predicted PLA(2) and lyso-PLA(2) activities based on what has been published for P. aeruginosa ExoU. RP534 also displayed PLA(1) activity under the conditions tested, wher...
متن کاملA comparative in vitro evaluation of self-assembled PTX-PLA and PTX-MPEG-PLA nanoparticles
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...
متن کاملEffect of different mass ratio of PLA: PEG segments in PLA-PEG-PLA copolymers on the physicochemical characterization and DNA release profile
Background: Adapting controlled release technologies to the delivery of DNA has the great potential to overcome extracellular barriers that limit gene delivery. This study investigates the effect of different mass ratio of PLA: PEG in the various tri block poly (lactic acid)-poly (ethylene glycol) - Poly (lactic acid) copolymer (PLA-PEG-PLA) on the properties of the resulting nanoparticles. Me...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولPLA 2 G 4 A ( phospholipase A 2 , group IVA ( cytosolic , calcium - dependent ) )
Description cPLA2alpha is an 85 kDa protein consisting of 749 amino acids. cPLA2alpha belongs to the alpha-beta hydrolase family which is identified by a characteristic nucleophile elbow with a consensus sequence of Sm-X-Nu-Sm (Sm = small residue, X = any residue and Nu = nucleophile). The protein contains an N-terminal C2 domain (Cadependent, phospholipid binding) and two catalytic domains (al...
