This report examines cAMP-induced regulation of directed organelle transport in bag cell neuron growth cones using video-enhanced differential interference contrast (DIC) microscopy (Allen et al., 1981; Inoue, 1981) and digital image analysis techniques. Under control conditions, organelle transport is evident in the central cytoplasmic regions of bag cell neuron growth cones, but not in lamell...

thio-Glycosides with a pseudo-disaccharide structure are synthesizedviaaziridine opening reactions starting from glycosyl thioacetates one-pot protocol, which affords glycomimetics equipped for easy and stable conjugation to aglycones.

background & aim: clematis is an ornamental and medicinal plant that is primarily planted as an ornamental plant. clematis orientalis is native to asia and central europe, used as an antiseptic and refrigerant. the propagation of clematis is very important. in this study, the effects of plant growth regulators on rooting and growth of the plants in vitro culture were examined. experimental:...

several plant growth regulators are used to improve the quality of cut flower in bulb plants, but their effectiveness depends on genotype and plant growth conditions such as nutrition status. a pot experiment was conducted under farm condition to study benzyl adenine (ba) and potassium nitrate interaction on floret diameter, stem diameter, flower height, flower number per bulb, fresh and dry we...

1. Endothelial cells were cultured in tissue culture flasks or on microcarrier beads and labeled with a lipid specific spin-label. 2. Exposure of endothelial cells to benzyl alcohol caused a dose- and time-dependent increase in membrane fluidity using electron spin resonance (ESR). Maximum fluidity was reached after a 5-min exposure to 100 mM benzyl alcohol. 3. Albumin permeability across endot...

In the title compound, [Cd(NCS)(2)(C(11)H(17)N(3))](n), the Cd(II) atom is octa-hedrally coordinated by the N,N',N''-tridentate Schiff base ligand and one terminal thio-cyanate N atom. Two trans-N:S-bridging thio-cyanates complete the N(5)S donor set around the Cd atom. In the crystal, adjacent Cd(II) ions are linked by the thio-cyanate N:S-bridges into polymeric chains along the c axis.

In the title compound, C(8)H(10)N(2)S, the o-tolyl group and the thio-urea core are planar. The mean planes of the two groups are almost perpendicular [82.19 (8)°]. The thio-urea group is in the thio-amide form, in which resonance is present. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯S hydrogen bonds, forming two infinite chains parallel to the (110) and (10) planes.

In the title compound, C(11)H(12)O(2)S, the C and S atoms of the central thio-phene and the methyl groups, and the two carbonyl groups of the cyclo-hepta-nedione are almost coplanar [maximum deviation from the mean plane = 0.221 (2) Å]. The packing is stabilized by π-π inter-actions between the conjugated thio-phenes, the shortest centroid-centroid distance between thio-phene rings being 3.9759...

An earlier computational study (CASPT2/pVDZ) by Winter et al. predicts the 3,5-bis(dimethylamino)benzyl cation to have nearly degenerate singlet and triplet states. Through product studies it is demonstrated that photolysis of 3,5-bis(dimethylamino)benzyl alcohol and its corresponding acetate and phenylacetate esters in alcoholic solvents produces a solvent incorporated adduct, 3,5-bis(dimethyl...

In eukaryotic cells the CDC7/DBF4 kinase, also known as DBF4-dependent kinase (DDK), is required for the firing of DNA replication origins. CDC7 is also involved in replication stress responses and its depletion sensitises cells to drugs that affect fork progression, including Topoisomerase 2 poisons. Although CDC7 is an important regulator of cell division, relatively few substrates and bona-f...
