gold nanoflower for selective detection of single arginine effect in α helix conformational change over lysine in 310 helix peptide
Bioconjugate Chemistry, 2019Co-Authors: Shahbaz Ahmad Lone, Kalyan K SadhuAbstract:Hydroxylamine-based Growth Reaction in the presence of natural l-amino acids (9 mM) and gold nanoparticle seed mostly produce aggregated or nonaggregated gold nanostructures except the cases of immediate precipitation with aspartic acid, glutamic acid, cysteine, and tyrosine. Among the other amino acids, arginine shows the control Growth Reaction to form gold nanoflower from gold nanoparticle seeds, which were preincubated with amine-modified DNA (NH2-oln). The absorbance trend with NH2-oln in the presence of arginine is similar to the aggregation behavior in the presence of histidine and methionine. The formations of gold nanoflower with arginine and aggregation due to histidine and methionine in the presence of NH2-oln were sorted out with lower concentration (50 μM) of these amino acids. This observation was successfully transferred to differentiate 310-helical Ac-(AAAAK)3A-NH2 from α-helical Ac-(AAAAR)3A-NH2. The concept was further applied for the detection of single arginine modification closest to ...

Gold Nanoflower for Selective Detection of Single Arginine Effect in α‑Helix Conformational Change over Lysine in 310-Helix Peptide

The concept was further applied for the detection of single arginine modification closest to the carboxy terminus of 310-helical Ac-(AAAAK)3A-NH2 peptide for maximum conformational change toward α-helix

Growth Reaction of young wild cherry (Prunus avium L.) trees to pruning
Journal of forest science, 2018Co-Authors: I. KupkaAbstract:A large crown is one of the most important prerequisites for the good Growth of a tree and therefore the crown could be called an engine of increment. The care for a large crown brings a decrease in the bole value at the same time as it makes large branches and later knots on it. Pruning is a possible solution of these two contradictions. Young wild cherry trees were pruned in three different ways: ( i) half of the crown left, ( ii) one quarter of the crown left and (iii) control, i.e. no pruning. The results show that height Growth was not influenced by pruning while diameter Growth was significantly affected. The crown reduction to a half means 10% less in diameter Growth within a 5-year period after pruning. The crown reduction to one quarter of the crown means only two thirds of 'full' diameter Growth on the control plot. The data suggest that the pruning of young wild cherry trees should be done moderately (more than a half of the crown should be left) and pruning should be done when the bottom part of the crown is in the shadow zone of the crown layer, not earlier.

Chemistry of Dimetallaoctaborane(12) with Chalcogen-Based Borate Ligands: Obedient versus Disobedient Clusters
Inorganic Chemistry, 2020Co-Authors: Chandan Nandi, Sourav Kar, Mohammad Zafar, Ketaki Kar, Thierry Roisnel, Vincent Dorcet, Sundargopal GhoshAbstract:The Reactions of dimetallaoctaboranes(12) [(Cp*M)BH] [M = Co () or Rh (); Cp* = η-CMe] with different chalcogen sources, such as Li[BHE] and Li[BHEPh] (E = S, Se, or Te), led to two unique Reaction outcomes. For example, the formation of 10-vertex -[(Cp*M)BEH] (, M = Co, E = S; , M = Co, E = Se; , M = Co, E = Te; , M = Rh, E = Se) from compounds and is a typical representation of a cluster Growth Reaction, while the formation of -[(Cp*Co)BH(EPh)] [E = S (), Se (), or Te ()] is a rare method that yielded clusters, keeping the core geometry identical. The formation of -- is a unique method that converts disobedient cluster to obedient clusters -. Further, the reactivity of - with various metal carbonyls presented sequential cluster Growth Reactions, which afforded 11-vertex -[(Cp*Co)BSeH{Fe(CO)}] () and 13-vertex fused -[(Cp*Co)BSeH{Ru(CO)}] (). The core geometry of - is uncommon and very similar to that of [CBH] with a unique open pentahapto-coordinating five-membered face.

Molecular layer epitaxy
Applied Surface Science, 1994Co-Authors: Jun-ichi NishizawaAbstract:Abstract For the purpose to clarify the process steps and to actualize the low temperature perfect crystal Growth technique, photo-excited Reactions in halide vapor phase epitaxy (VPE) and in metalorganic CVD (MO-CVD), adsorption and surface Reaction processes in molecular layer epitaxy are investigated. Based on these results synchronized photo-excitation and synchronized temperature excitation in molecular layer epitaxy is introduced as the individual excitation of each process step of the Growth Reaction.
