In order to improve the performance of allyl starch-g-poly(acrylic acid-co-acrylate) sizes, effect of molecular structure of the acrylate monomers grafted onto allyl starch has been studied. A series of acrylates including methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BA) and 2-ethylhexyl acrylate (EHA) have been grafted onto allyl starch with the same degree of substitution throug...

The objective of this study was to compare the modulatory effect of garlic oil and its three organosulfur compounds, diallyl sulfide (DAS), diallyl disulfide (DADS), and diallyl trisulfide (DATS), on rat hepatic detoxification enzyme activity, and protein and mRNA expression. Rats were orally administered garlic oil (80 or 200 mg/kg bw), DAS (20 or 80 mg/kg bw), DADS (80 mg/kg bw), or DATS (70 ...

Glucosinolates, such as sinigrin, and S-methyl cysteine sulphoxide (SMCO), which are found in forage brassica species have been implicated in the low intakes observed among lambs consuming such diets. To test both the individual and interactive effects of these compounds in sheep, all combinations of the sinigrin breakdown products, allyl cyanide (ACN) and allyl isothiocyanate (AITC; 10 mmol/d)...

The aim of this research was to evaluate acute toxicity of the essential oil of leaves of Chinese chives, Allium tuberosum Rottler ex Spreng (Asparagales: Alliaceae) and its major constituents against Apolygus lucorum Meyer-Dür (Hemiptera: Miridae). The essential oil of A. tuberosum leaves was obtained by hydrodistillation and analyzed by gas chromatography and gas chromatography-mass spectrome...

Addition of PMe3 to Mo2(allyl)4 afforded Mo2(allyl)4(PMe3)2, in which two of the allyl groups adopt an unprecedented micro2-eta1,eta3 bonding mode; theoretical studies elucidate the roles of the sigma- and pi-donor ligands in the interplay of metal-allyl and metal-metal bonding.

Ethyl carbamate and a series of related compounds were given in single intraperitoneal doses to pregnant Syrian hamsters on Day 8 of gestation, and fetuses were examined for malformations on Day 13 of gestation. Urethan produced a variety of malforma tions and growth retardation. Of the compounds modified in the carboethoxy end, n-propyl carbamate was as teratogenic as the ethyl carbamate, and ...

The thiosemicarbazides 3a-c were appeared by reaction of the corresponding substituted hydrazides 1a-c with allylisothiocyanate 2. Synthesis of some novel 1,2,4-triazole-thiols 4a-c bearing a pyridyl unit using 1-(x-picolinoyl)-4-allyl-thiosemicarbazides (x = 2,3,4) in an alkaline solution, is reported. Also, the S-alkylation of triazole derivatives 5-7a-c is described. The structure of the syn...

Lipoxygenases have been proposed to be a possible factor that is responsible for the pathology of certain diseases, including ischaemic injury. In the peroxidation process of linoleic acid by lipoxygenase, the E,Z-linoleate allyl radical-lipoxygenase complex seems to be generated as an intermediate. In the present study, we evaluated whether E,Z-linoleate allyl radicals on the enzyme are scaven...

Pistachio nut is a strategic product throughout the world, especially in Iran. There are some problems that reduce production and export of pistachios, for example, postharvest fungi, especially Aspergillus spp., that lead to production of mycotoxins. Nowadays the use of chemical and synthetic antifungals is discouraged and reduced because of health risks to mankind and nature. In present study...
