Advanced Functional Materials, EarlyView.A self‐gelling PG@PAC (POD/Gel‐CDH@PA/CHX) powder is developed for infected burn care in austere settings. Upon contact with wound exudate, it instantly forms an adhesive hydrogel, providing simultaneous hemostasis, broad‐spectrum antibacterial activity, reactive oxygen species scavenging, and immunomodulation. In a murine model of S.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents
Advanced Functional Materials, EarlyView.Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence
Advanced Functional Materials, EarlyView.Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...

Toxicology and Applied Pharmacology, 1965
Abstract The effects of feeding cube powder to rats for two years at dietary levels of 50, 100, 250, 500, and 1000 ppm, and to dogs for 28 months at levels of 50, 150, and 400 ppm have been presented. Cube at all levels, except 50 ppm, inhibited growth of rats. No histopathologic change attributable to cube ingestion was noted at any level.

Automatisation of chronic toxicities
Computer Programs in Biomedicine, 1978Automatisation of collection and processing of chronic toxicity tests are presented in a 'pharmaceutical research center environment'. The data are either analog signals or numerical values transmitted to the computer, from terminals posted in various laboratories.

Nature, 1965
CERTAIN types of hazard consequent on the administration of chemical substances are estimated by the performance of chronic toxicity tests. Such tests are usually designed according to certain empirical rules. Groups of animals (commonly three) are given a test substance in regularly repeated doses of constant size, each group receiving a different ...

Chronic Toxicity of Metrifonate
Acta Pharmacologica et Toxicologica, 1981Abstract From chronic toxicity studies with metrifonate (identical with trichlorfon) on different animal species, the following conclusion can be reached: 1. There is no conclusive evidence that trichlorfon has a carcinogenic effect. 2. There is no indication that trichlorfon has a significant cumulative toxic effect. 3.

Chronic Toxicity of Polyphenyl Mixtures
American Industrial Hygiene Association Journal, 1965Abstract In rats the ingestion of Santowax OM, a mixture of terphenyls used as a coolant, and Omre High Boilers over prolonged periods inhibits weight gain and leads to anemia and kidney and liver damage. At a daily dietary intake of 350 mg/kg or more, Santowax OM produces degenerative changes in the nephron; the Omre High Boilers at a daily dietary ...
