The pulmonary effects of two environmentally relevant aldehydes were investigated in nonsensitized or ovalbumin (OA)-sensitized guineapigs (GPs). Four-week-old male Hartley GPs, weighing about 400 g, were intraperitoneally injected with 1 ml of an NaCl solution containing 100 microg OA and 100 mg Al(OH)(3). They were then exposed to either acetaldehyde (200 ppb) or benzaldehyde (500 ppb) for 4 ...

The carbonyl-carbon kinetic isotope effect (KIE) and the substituent effect were measured for the reaction of phenylthiomethyllithium (PhSCH(2)Li, 1) with benzaldehyde and benzophenone, and cyanomethyllithium (NCCH(2)Li, 2) with benzaldehyde, and the results were compared with those for other lithium reagents such as MeLi, PhLi, CH(2)=CHCH(2)Li, and CH(2)=C(OLi)C(CH(3))(3). It was previously sh...

Green leaf bug Apolygus lucorum (Meyer-Dür) is one of the major pests in agriculture. Management of A. lucorum was largely achieved by using pesticides. However, the increasing population of A. lucorum since growing Bt cotton widely and the increased awareness of ecoenvironment and agricultural product safety makes their population-control very challenging. Therefore this study was conducted to...

The aim of this study was to synthesize and evaluate anticancer activity 2-hydroxy benzaldehyde 4-hydroxy thiosemicarbazone (2-HBTSc 4-HBTSc) against MCF-7 breast cancer cell line. ligands were prepared characterized by UV vis, IR NMR. MTT assay used assess viability cells. RNA isolation, extraction cDNA synthesis done. Then all groups subjected RT-qPCR using Gene expression specific primers. A...

The amino acid-catalysed retroaldol condensation previously described for citral has been extended to other α,β-unsaturated aldehydes. In the presence of glycine and an elevated pH, six other α,β-unsaturated aldehydes also underwent retroaldol condensation. Crotonaldehyde, as well as its proposed intermediate, aldol, were converted into acetaldehyde. Hexenal, decenal, methyl crotonaldehyde, far...

Catalytic oxidation of styrene has attracted extensive attention in industries and academia. Benzaldehyde, one the derived valuable aromatic aldehyde products, been extensively applied perfume, pharmacy, dye industries. However, it is difficult to achieve a high yield by transforming into benzaldehyde with sustainable supply active catalysts. Furthermore, conventional catalyst species inevitabl...

Abstract Selective photooxidation of aromatic alcohols to corresponding aldehydes is a widely used model reaction for evaluation performance heterogeneous photocatalysts. A top example the photocatalytic production hydrogen peroxide via reduction dioxygen with concomitant benzyl alcohol benzaldehyde. Herein we demonstrate ability benzaldehyde promote auto‐photocatalytic oxidation and produce la...

ammonia is the chief excretory product in fishes. however, non-availability of enough of water in the habitat, may lead to the formation of urea, in fishes. in the present study, the possible role of urea formation to avoid the toxicity of ammonia under water-restricted condition was tested in channa gachua. circulatory urea and ammonia were estimated in the blood of the fishes and glutamate de...
