We aimed to evaluate the role of a synthetic somatostatin analogue in delay procedure of experimental skin flaps. Thirty-six rats were randomly divided into 2 groups of 18 each to compare the possible local ischemic effect of octreotide with that of surgical delay in the dorsal random pattern skin flap model. The indu…
The inhibition effect of 2-carboxymethylthio-4-(p-methoxyphenyl)-6-oxo-1,6-dihy-dropyrimidine-5-carbonitrile (CPD) towards the corrosion of copper was studied in aerated stagnant 3.5% NaCl at 25 °C using ac techniques include electrochemical frequency modulation and electrochemical impedance spectroscopy as well as po…
Naturally occurring foam constituent and surfactant proteins with intriguing structures and functions are now being identified from a variety of biological sources. The ranaspumins from tropical frog foam nests comprise a range of proteins with a mixture of surfactant, carbohydrate binding and antimicrobial activities…
The high reset current IR in unipolar resistance switching now poses major obstacles to practical applications in memory devices. In particular, the first IR-value after the forming process is so high that the capacitors sometimes do not exhibit reliable unipolar resistance switching. We found that the compliance curr…
We report on early stages of submonolayer Ag island coarsening on Ag(111) surface at room temperature ($300$ K) carried out using realistic kinetic Monte Carlo (KMC) simulations. We find that during early stages, coarsening proceeds as a sequence of selected island sizes creating peaks and valleys in the island size d…
There is an increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, chemistry, energy and medicine. Metallic nanoparticles are traditionally synthesized by wet chemical techniques, where the chemicals used are quite often toxic and flammable. In t…
The hydrodenitrogenation (HDN) experiments of quinoline,indole and carbazole,respectively,in the 4,6-DMDBT toluene solution with w(S) of 849 μg/g were carried out under the conditions of 280℃,total pressure 2 MPa,V(H2)/V(Oil)=300 and the liquid hourly space velocity 5 h-1,to investigate self-inhibition for HDN of the…

MORC3 の PML-nuclear body への局在化機構 要旨 哺乳動物の細胞核には、多くの機能的サブコンパートメントが存在している。そのサブコンパ ートメントの一つである PML-NBs(promyelocytic leukemia-nuclear bodies)は、主として PML タン パクにより構成された構造体である。この PML-NBs は様々なタンパクが一時的に、または恒常的 に局在化することで細胞周期や転写、アポトーシス、細胞老化などの様々な細胞プロセスを制御す ることが知られている。PML-NBs に局在化しているタンパクの一つである MORC3 (microchidia family CW-type zi…
Abstract Recent advances in dendrimer‐based nanomedicine show that dendrimers have been used in many different ways in medical applications. Dendrimer can be used as a platform to covalently conjugate targeting moieties and to physically encapsulate drug molecules inside their interior to improve the water solubility…
Because of the increase in dose at the end of the range of ions, dose delivery during patient treatment with hadrontherapy should be controlled with high precision. Monte Carlo codes are now considered mandatory for validation of clinical treatment planing and as a new tool for dosimetry of ion beams. In this work, we…
The convergence of significantly different and disparate technologies such as spintronics, carbon nano tube field effect transistors, photon and bio-responsive molecular switches, memristor and memristive systems and metamaterials, coupled with energy scavenging sources are gaining a renewed focus in the quest for new…
Copolymers of p-bromophenyl acrylamide with methyl methacrylate were prepared and characterized using microanalysis and IR spectroscopy. The reactivity ratio values of the copolymerization were calculated using 1HNMR technique. Thermal analyses of the copolymers showed that the stability are intermediate between poly(…
Abstract A set of dendritic‐linear copolymers, poly(maleic anhydride‐grafted‐3,3′‐dimethyl‐(4‐aminophenylazanediyl)bis(2‐methylpropanoate))‐random‐polystyrene (PMA‐APM‐r‐PS), was successfully prepared by copolymerization of the novel dendritic macromonomer, 4‐(4‐(bis(3‐(4‐(bis(3‐methoxy‐2‐methyl‐3‐oxopropyl)amino)phen…
The inside cover shows a structural model of DNA-wrapped single-walled carbon nanotubes with an AFM image of the DNA-SWNT network in the background. DNA-SWNTs provide an effective, scalable method of fabricating super-uniform networks of highly isolated, structure-sorted SWNTs for high-performance thin-film transistor…
폴리스테린을 주형으로 사용하여 순수한 매크로포러스 실리카 지지체를 졸겔법에 의하여 제조하였으며, 은 입자가 매크로 기공 안에 균일하게 분산되어 있는 매크로포러스 은/실리카 복합소재를 성공적으로 제조하였다. 순수한 실리카 다공체는 폴리스테린 크기에 따라 100 nm와 200 nm의 균일한 기공을 가지고 있었으며 이는 폴리스테린의 크기에 따라 기공크기를 제어할 수 있었다. 매크로포러스 은/실리카 기공의 크기 제어와 $AgNO_3$ 의 농도에 따른 미세구조를 관찰한 결과 TEOS의 3 wt% $AgNO_3$ 를 사용한 것이 가장 이상적인 균일한 기공의 분포를 나타내었다.…
Cover: The morphology of hybrid polymer/clay particles synthesized by miniemulsion polymerization has a significant impact on film properties. The morphology of the hybrid droplets controls the morphology achieved upon polymerization, which depends on the interfacial tensions of the modified (hydrophobized) clay with…
In the title compound, [Co(C(5)H(3)N(4)O)(N(3))(H(2)O)](n), the cobalt ion is coordinated by three N atoms of two organic ligands, two N atoms of two azide anions and one water mol-ecule in a distorted octa-hedral geometry. The metal atoms are connected via the ligands into layers, which are further connected by O-H⋯N…
Active materials, and their subsequent use in adaptive structures, have been the subject of increasing attention recently. For example, the ability of shape memory polymers to switch between relatively low and high elastic moduli makes them attractive candidates for implementation in ambitious engineering designs requ…
In the above titled paper (ibid., vol. 46, no. 2, pp. 258-261, Feb. 10), there is a wrong sign in equation (6) on page 261. The right expression of the Melnikov function is presented here. The expressions corresponding to Hopf bifurcation - equation (7) - and semi-stable bifurcation - equation 8 - are correct.
