Objectives: To outline the development and validation of a universal method for quantifying deltamethrin, permethrin and alpha-cypermethrin levels in a variety of long-lasting insecticidal mosquito nets.
Methods: Using the HPLC conditions found in the CIPAC method for deltamethrin quantification, the method is based on a simple extraction technique for sample preparation (heating in isooctane at approximately 100 °C for 15 min). The method was validated for linearity, specificity, accuracy, precision, insecticide stability to extraction conditions and required extraction time for insecticide removal.
Results: The method was found valid for insecticide quantifications for various types of nets, namely for deltamethrin coated on polyester nets, deltamethrin incorporated into polyethylene nets, permethrin incorporated into polyethylene nets, alpha-cypermethrin coated on polyester nets and alpha-cypermethrin incorporated into polyethylene nets.
Conclusions: This method will provide a more simplified approach to testing a variety of nets (different types of fibre) containing deltamethrin, permethrin or alpha-cypermethrin.

Self-healable, multilayered organosiloxane films were prepared thermal conversion of lamellar organosiloxane films containing poly(ethylene oxide)-polydimethylsiloxane-poly(ethylene oxide) block copolymers. The incorporation of silanolate groups enabled crack healing through dynamic siloxane equilibration. The enhanced hardness and suppressed cyclic siloxane formation resulting from the multilayered structure exhibit potential for practical applications.

Biodegradable plastics are increasingly utilized in packaging, driven by green chemistry and environmental responsibility. Among them, poly(L-lactic acid) (PLLA) stands out due to its biodegradability and biocompatibility. However, its limited gas permeability and selectivity hinder its application in produce preservation.

Background: Periprosthetic joint infections (PJIs) are a major complication of total joint replacement surgeries. This study investigated the enhancement of mechanical properties and antibiotic release in ultra-high molecular weight polyethylene (UHMWPE) through the encapsulation of submicron gentamicin sulfate (GS) particles, addressing the critical need for improved implant materials in orthopaedic surgery, particularly in managing PJIs.
Methods: The present study involved embedding submicron GS particles into UHMWPE flakes at concentrations of 2% to 10% by weight.

Introduction: The minority of the chronic hepatitis B (CHB) patients received polyethylene glycol interferon (PEG-IFN) combined with nucleotide analogs (NAs) can obtain hepatitis B surface antigen (HBsAg) clearance.
Methods: In order to find out the advantaged population, we retrospectively collected 122 CHB patients treated with NAs alone or NAs plus PEG-IFN for 48 weeks, who were admitted to Sun Yat-sen Memorial Hospital from 2019 to 2024.
Results: We found HBsAg clearance rate in NAs plus PEG-IFN group was 40.
