This paper appraises an HPLC method for assaying phospholipase A2 (PLA2).The procedure is based on heptane-isopropanol-H2SO4 extraction of fatty acids released by the enzyme in the presence of margaric acid as an internal standard, and precolumn derivatization with 9-anthryldiazomethane.The derivatives of naturally occurring long-chain fatty acids
RLXSS: Optimizing XSS Detection Model to Defend Against Adversarial Attacks Based on Reinforcement Learning
With the development of artificial intelligence, machine learning algorithms and deep learning algorithms are widely applied to attack detection models.Adversarial attacks against artificial intelligence models become inevitable problems when there is a lack of research on the cross-site scripting (XSS) attack detection model for defense against at
Synthesis and Thermal Properties of Novel Biodegradable ABCBA Pentablock Copolymers from Poly (Ethylene glycol), L-Lactide and p-Dioxanone
In this work, new biodegradable ABCBA type pentablock copolymers with different mole wig ratio of L-lactide and PPDO-b-PEG-b-PPDO triblock copolymer were synthesized and characterized.In the first step, PPDO-b-PEG-b-PPDO triblock copolymer was synthesized via a ring-opening polymerization of P-DiOxanone (PDO) monomer with Poly (Ethylene Glycol) (PE
Deubiquitination of epidermal growth factor receptor by ubiquitin-specific peptidase 54 enhances drug sensitivity to gefitinib in gefitinib-resistant non-small cell lung cancer cells.
Youth Roping Style Saddle A precise balance between ubiquitination and deubiquitination is crucial for cellular regulation.Ubiquitin-specific peptidase 54 (USP54), an active deubiquitinase (DUB), modulates the ubiquitination of the epidermal growth factor receptor (EGFR).While the significance of USP54 in tumorigenesis is known, its specific functi
