Synaptic vesicles (SVs) fuse at a specialized membrane domain called the active zone (AZ), covered by a conserved cytomatrix. How exactly cytomatrix components intersect with SV release remains insufficiently understood. We showed previously that loss of the Drosophila melanogaster ELKS family protein Bruchpilot (BRP) eliminates the cytomatrix (T bar) and declusters Ca(2+) channels. In this pap...
Abstract The amino acid l -methionine is an essential and commonly used as a feed supplement in terrestrial animals. It less suitable for marine organisms because it readily excreted. also highly water soluble this results loss of the eutrophication water. To address these problems, dipeptide dl -methionyl- (trade name: AQUAVI Met-Met) has been developed dedicated methionine source aquaculture....
A water-soluble coordination cage was obtained by reaction of Pd(NO3)2 with a 1,3-di(pyridin-3-yl)benzene ligand featuring short PEG chain. The cavity the metal-organic contains one nitrate anion, which is readily replaced chloride. apparent association constant for chloride binding in buffered aqueous solution Ka=1.8(±0.1)×105 M−1. This value significantly higher than what has been reported ot...
A new modular photochemical continuous stirred-tank reactor (CSTR) design is described, based upon the development of light-source units that can be fitted to previously described fReactor CSTR platform. In addition use in homogeneous reactions (e.g., photoredox-catalyzed hydroamination), these are especially well suited handling multiphasic mixtures, exemplified here solid–liquid (Wohl–Ziegler...
Correlation between components of Q/I and wheat (Triticum aestivum L.) growth indices was studied in a greenhouse experiment during 2003-04 growing season. Eighty soil samples (0 – 30 cm depth) were collected randomly in farms around the Abyak region, Ghazvin province. Twenty-one samples were then selected based on soil texture and NH4OAC-K. The research included treatments of 21 soils and two ...
Many rare and valuable ancient specimens now carry the scars of ancient DNA research, as questions of population genetics and phylogeography require larger sample sets. This fuels the demand for reliable techniques to screen for DNA preservation prior to destructive sampling. Only one such technique has been widely adopted: the extent of aspartic acid racemization (AAR). The kinetics of AAR are...
A low lipid, high starch containing tissue, namely cotyledons of germinating pea seedlings was examined for its capacity to synthesize fatty acid. Intact tissue slices readily incorporate acetate-(14)C into fatty acids from C(16) to C(24). Although crude homogenates synthesize primarily 16:0 and 18:0 from malonyl CoA, subsequent fractionation into a 10,000g pellet, a 10(5)g pellet and supernata...
The intraleucocytic fate of a variety of P(32)- and C(14)-labeled bacteria has been studied in both polymorphonuclear leucocytes and macrophages. Both cell types brought about extensive degradation of bacterial lipids, nucleic acids, and proteins. Intracellular breakdown was primarily dependant upon the composition of the ingested particle rather than on the type or source of the phagocyte. Evi...
