All the chemicals used in the present study were of analytical grade and were obtained from standard companies. ELISA plates, tissue culture plates (96 /8 well), culture dishes, Serological plates, Roux culture bottles, 0.2μm sterile syringe filters (non-pyrogenic). DMBA (7,12-Dimethylbenzylanhracene), TPA (12-O-tetradecanoylphorbol13-acetate), RPMI 1640 (Rose Well Park Memorial Institute Lab n...

Acid fuels the motion of a threaded ring A central goal in the construction of molecular-scale machines is the efficient achievement of oneway motion. Erbas-Cakmak et al. developed a class of machines that transmit pH changes into the two-stage guided motion of molecular rings threaded on a linear or cyclic axle. The design relies on temporary blocking groups and landing sites along the axle th...

In a defined medium with added ethionine plus low methionine, phenylalanine, tryptophan, tyrosine, adenine, and additional methionine reversed inhibition of the enteric yeast Candida slooffii by ethionine. Isoleucine and 7-methylguanine restored half-maximal growth. Choline but not triethylcholine inhibited C. slooffii. 6-Mercaptopurine reversed ethionine inhibition and also synergistic inhibit...

In the title compound, C(12)H(16)N(3)O(2)·C(2)HCl(3)O(2), the imidazolidine ring adopts a twist conformation. The crystal structure is stabilized by inter-molecular O-H⋯N hydrogen bonds.

HIS STUDY WAS UNDERTAKEN IN AN ATTEMPT to evaluate some of the more promising methods for the determination of cerebrospinal fluid protein with the objective of deciding on the most suitable one for use in this laboratory. There are a number of methods available, with great variations in the ease of performance and the accuracy of results; therefore it seems that some sort of compromise must be...

In the title salt adduct, C(17)H(21)ClN(2) (2+)·2C(2)Cl(3)O(2) (-)·C(2)HCl(3)O(2), the Cl atom of the dication is disordered over two positions in a 0.915 (3):0.085 (3) ratio. The Cl atoms in the trichloroacetate anions and trichloroacetic acid molecule are also disordered, with refined site-occupation factors of 0.59 (3):0.41 (3), 0.503 (12):0.417 (12) and 0.653 (12):0.347 (12). The piperazine...
