BACKGROUND Rapid urbanization, westernization of lifestyles, poor quality of objects available and extremely relaxed vigilance on adherence to 'product safety guidelines' make any developing country like India highly susceptible to allergic contact dermatitis (ACD) even in children. There has been no previous attempts to assess the magnitude of childhood ACD in India. AIMS To assess the clini...

Organophilic groups of coupling agents can be the key factor for electrical performance Boron Nitride (BN)/meta-aramid composite paper. In this article, four types triethoxy-silane with different organophilic groups, including mercapto-propyl (MP), glycidylether-propyl (GP), amino-propyl (AP) and trideca-fluoro-octyl (TFO) were studied. The structural properties modified papers compared, molecu...

The title compound, C12H18N4O6S (systematic name: 4-di-propyl-amino-3,5-di-nitro-benzene-sulfonamide), is a sulfonamide with herbicidal properties marketed as oryzalin. The dihedral angles between the benzene ring and the mean planes of the nitro groups are 26.15 (11) and 54.80 (9)°. The propyl arms of the di-propyl-amino substituent lie on opposite sides of this ring plane. In the crystal, N-H...

As one of the oldest distillates in the world, flavor compounds of Chinese Baijiu (Chinese liquor) were extremely complex. Propyl lactate was firstly detected by direct injection and gas chromatography-mass spectrometry (GC-MS) in 72 Chinese Baijius. The objectives were to detect the contents of propyl lactate and evaluate its contribution to the aroma of Chinese Baijiu based on odor activity va...

Gametangia of the aquatic phycomycete Allomyces macrogynus have a cyanide- and antimycin A-insensitive respiration, which is sensitive to salicylhydroxamic acid (alternative respiration). Propyl gallate is also an inhibitor of this alternative pathway, and propyl gallate is more efficient than hydroxamic acid. Gametangial respiration is insensitive to propyl gallate, but propyl gallate sensitiv...

Two independent mol-ecules comprise the asymmetric unit in the title thio-carbamide derivative, C(10)H(13)NOS. These differ in the relative orientations of terminal ethyl groups [C-C-C-O torsion angles = -66.95 (13) and 55.92 (13)°, respectively]. The phenyl ring is twisted out of the plane of the central residue [C(q)-N-C(ph)-C(ph) = -146.20 (12) and -144.15 (12)°, respectively; q = quaternary...

Background: Antioxidants are food additives in oil and fat products usually to decrease the process of rancidity by preventing the oxidation such as in margarine. BHA, BHT, propyl gallate, and TBHQ are commonly used antioxidants. Combinations of antioxidants are generally used in the food product. Therefore, analytical method which is capable to measure the antioxidants simultaneously, is requi...

Photoswitching and fluorescent properties of sulfone derivatives of 1,2-bis(2-alkyl-4-methyl-5-phenyl-3-thienyl)perfluorocyclopentene, 1-5, having methyl, ethyl, n-propyl, i-propyl, and i-butyl substituents at the reactive carbons (2- and 2'-positions) of the thiophene 1,1-dioxide rings were studied. Diarylethenes 1-5 underwent isomerization reactions between open-ring and closed-ring forms upo...
