Most protective clothing research for workers exposed to pesticides has focused on the primary dermal exposure that results from direct contact with the pesticide and on the penetration, versus repellency, of protective materials. The role of absorption and retention in the function of traditional clothing materials to limit pesticide exposure has received less attention. This project investigates the transfer of pesticides from contaminated work clothing in the dry state to human skin with the goal of furthering our understanding of the role of absorption and retention in the function of traditional clothing materials. Our objective was to study the use of synthetic membrane to evaluate the kinetic transport of pesticide from contaminated clothing through human skin. Transport of pesticide through the test system with and without the presence of fabric was characterized by a three-parameter single exponential rise to maximum equation. The synthetic membrane system was an appropriate model for human skin in this situation. Starching applied to the fabric gave additional absorption and retention, reducing pesticide transport from the fabric to the skin, and heavier weight fabric, such as denim, provided protection through absorption and retention of the pesticide.

Atopic dermatitis (AD) is a chronic disorder affecting millions worldwide. Recent advancements suggest that combining therapies can significantly improve AD treatment outcomes and mitigate the challenges of long-term drug use, particularly with corticosteroids. In this study, we developed a 3D-printed hydrogel composed of gelatin (Gel) and dialdehyde starch (DAS), capable of encapsulating and delivering hydrocortisone (HC).

Elevating the upper cutoff voltage to 4.6 V could effectively increase the reversible capacity of LiCoO (LCO) cathode, whereas the irreversible structural transition, unstable electrode/electrolyte interface and potentially induced safety hazards severely hinder its industrial application. Building a robust cathode/electrolyte interface film by electrolyte engineering is one of the efficient approaches to boost the performance of high-voltage LCO (HV-LCO); however, the elusive interfacial chemistry poses substantial challenges to the rational design of highly compatible electrolytes.

For millennia, aloe vera (AV) and eucalyptus oil (EO) have been recognized as natural sources of healing and have been utilized for medicinal purposes in the realm of health. As an attempt to treat pressure sores, AV and eucalyptus oil were added as supplements to biocompatible and biodegradable poly (ethylene oxide) (PEO) polymer to synthesize nano and micro fibrous wound dressings by the electrospinning process. Additive solubility in polymeric matrix is the key parameter to achieve the synthesis of homogeneous fibers with controlled release of therapeutic oils, cure and humidity; therefore, lecithin as herbal (soybean) based emulsifier was used to control additive/polymer solubility.

Efficient oral coassembly strategies have attracted increasing attention for the preferable co-delivery of multiple nutraceuticals. Inspired by superior transport tendencies of the intestinal glucose transporter 2 (GLUT2) to fructose-modified biopolymers, this study fabricated the coassemblies consisting of fructose-modified chitosan (Fru-CS) shell and disulfonic acid-modified γ-cyclodextrin (BA-γ-CD) core to effectively co-deliver hydrophilic egg white oligopeptides (EWOP) and hydrophobic curcumin (Cur). The non-covalent interactions-driven coassemblies exhibited the admirable nanoscale colloidal features and nutraceuticals (EWOP/Cur) co-loading capacity (20.

In this paper, corn starch was used as the base material, and 3-chloro-2-hydroxypropyl trimethyl ammonium chloride was used as a cationic surfactant to modify it. Subsequently, acrylic acid was then used as the primary raw material, and through the combined action of potassium persulfate and N,N'-methylene bisacrylamide, a cationic modified starch grafted acrylic-based water-absorbent resin dust suppressant (CACS) is synthesized via graft polymerization. During the preparation process, the water absorption performance is employed as the key indicator to optimize the process parameters: the degree of neutralization of acrylic acid is set at 50%, the mass ratio of corn starch to acrylic acid is 10 wt%, the volume ratio of CHPTA to acrylic acid is 1:20, the initiator concentration is 0.
