Convulsant Effects of Semicarbazide in Epileptic Monkeys.
Experimental Biology and Medicine, 1956 Summary(1) Threshold convulsant dosages to rapid intravenous injection of semicarbazide were significantly lower in chronically epileptic monkeys than in normal unoperated controls. (2) Clinical seizures following intravenous injection of threshold convulsant doses of semicarbazide occurred after a latent period of 2 to 3 1/2 hours. With suprathreshold

Hazelnut: Explorations toward the Biocatalytic Synthesis of its Aroma Precursor
ChemBioChem, Volume 26, Issue 16, September 12, 2025.This article proposes a biosynthetic route for synthesizing filbertone, the principal flavor compound of hazelnut, through a multienzyme cascade. The pathway uses D‐amino acid oxidase, threonine deaminase, and a regioselective transketolase from Geobacillus stearothermophilus to produce a sustainable, natural hazelnut aroma precursor, addressing ...

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.ABSTRACT Nitrofuran metabolites, including semicarbazide, pose significant risks to food safety, particularly in the aquatic industry. Bangladesh's shrimp industry faced major challenges due to nitrofuran contamination, leading to a voluntary export suspension to the European Union (EU).

Partially Biobased Self‐Repairing Poly(Aspartic Ester Polyurea) Coatings
Polymer Engineering &Science, Volume 65, Issue 8, Page 4155-4169, August 2025.Sustainable self‐healing PAEU coatings, containing various amounts of disulfide derived from poly(aspartic esters) and biobased polyisocyanates, were created. ABSTRACT Poly(aspartic ester polyurea) (PAEU) coating systems, which feature an uncatalyzed and solventless reaction, have attracted attention as a more environmentally friendly, nonreactive ...

Chemie Ingenieur Technik, Volume 97, Issue 7, Page 677-688, July 2025.Kommunale Kläranlagen gelten als Haupteintragspfad organischer Mikroschadstoffe in die aquatische Umwelt. Ein Großteil der Arzneimittelrückstände und Industriechemikalien wird in Kläranlagen nicht oder nur teilweise entfernt. Um einen qualitativ höheren Kläranlagen‐Ablauf zu erzeugen, wird eine Kombination aus hybridem Teilstrom‐Membran‐Bioreaktor mit ...

Identification of inhibitors of the Salmonella FraB deglycase, a drug target
FEBS Open Bio, Volume 15, Issue 5, Page 773-792, May 2025.A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.
