Aquatic organisms are exposed to mixtures of chemicals that may interact. Mixtures atrazine (ATR) and chlorpyrifos (CPF) elicit synergic effects on the permanent inhibition acetylcholinesterase (AChE) in certain aquatic organisms, causing severe damage. Mechanistic mathematical models toxicokinetics toxicodynamics (TD) be used better characterize understand interactions these two chemicals. In ...

Feruloyl esterase forms a part of the enzyme complex that acts collectively and synergistically to completely hydrolyze xylan to its monomers. The enzyme has found potential uses in a wide variety of applications of interest to the agrifood and pharmaceutical industries. This review describes the enzymology of feruloyl esterases involved in xylan degradation. The occurrence of feruloyl esterase...

The activity and expression levels of alcohol dehydrogenase, glucose-6-phosphate dehydrogenase and non-specific soluble esterase were compared in the seven species (C. lyoni, Hersilia sp. Oxyopes sp., Menemerus bivittatus, Leucauge decorata, Selenops sp. and Cyrtophora citricola) from the semi-arid habitat of Agra region. Three predominant non-specific esterases loci (Est1, Est2 and Est3) were ...

Abstract. Witasari LD, Huang FC, Schwab W. 2022. Identification and characterization of strawberry FvGELP1 (Fragaria vesca GDSL esterase/lipase).Biodiversitas 23: 907-915. Fruit softening is primarily the result hydrolytic enzymes activity. Esterases are reasonable candidates due to their putative role in cell wall components degradation. This study aimed identify characterize a new enzyme rela...

fumigant toxicity of camphor was studied against the aphid aphis craccivora koch and three associated natural enemies, i.e. coccinella undecimpunctata l., aphelinus albipodus hayat & fatima and aphidius colemani viereck. aphis craccivora was the most tolerant one compared with all tested natural enemies as the recorded lc50 values were 12.71, 6.33, 1.16 and 0.48 mg camphor/liter space for t...

recent years considerable interest has developed in the genetic control of ';rotein determination in metazoan species. In the house mouse the genetic specification of histocompatibility antigens (SNELL 1963; KLEIN 1963), gammaglobulin (HERZENBERG, MISHELL, and HERZENBERG 1963), and hemoglobins (RUSSELL and GERALD 1958; POPP 1963) have been carefully studied, and a number of distinct mutant form...

ABSTRACT. In this study, five different thiourea derivatives were synthesized from aryl amines according to the reported method. 1-Benzoyl-3-(4-methoxyphenyl)thiourea (2) was confirmed with single crystal XRD analysis while 1-benzoyl-3-phenylthiourea (1), 1-benzoyl-3-(4-hydroxyphenyl)thiourea (3), 1-benzoyl-3-(2-nitrophenyl) (4) and 1-benzoyl-3-p-tolylthiourea (5) elucidated FTIR NMR techniques...

Earthworms are common organisms in soil toxicity-testing framework, and endogeic species currently recommended due to their ecological role agroecosystem. However, little is known on pesticide metabolic capacities. We firstly compared the baseline activity of B-esterases glutathione-S-transferase Allolobophora chlorotica Aporrectodea caliginosa. Secondly, vulnerability these exposure was assess...
