BACKGROUND: Apoptotic neuronal death is known as programmed cell death. Inhibition of this progression might contribute to a new treatment strategy. However, methods for in vivo detection of live apoptotic cells are in need to be developed and established. CONTEXT AND PURPOSE: The purpose of this study is to develop a…
This work demonstrated two different kinds of magneto-transport behaviors in epitaxial L10 MnAl film as a function of temperature. The magneto-resistance ratio (MR) was negative and exhibited evident enhancement in the resistivity at coercive fields above 175 K. The MR enhancement was attributed to the increase in the…
Abstract Divalent transition metal (T) nitroprussides form a series of insoluble coordination compounds, which generally crystallize in 3D frameworks, except for a layered (2D) phase of copper. In this contribution, the preparation of layered phases for T = Mn, Fe, Co, Ni, Zn, and Cd is reported. The incorporation of…
On the surface of 2D topological insulators, 1D quantum spin Hall (QSH) edge modes occur with Dirac-like dispersion. Unlike quantum Hall (QH) edge modes, which occur at high magnetic fields in 2D electron gases, the occurrence of QSH edge modes is due to spin-orbit scattering in the bulk of the material. These QSH edg…
In this paper, we present the synthesis of TiO 2 nanotube (NT) arrays formed by anodization of Ti film deposited on a fluorine-doped tin oxide-coated glass substrate by direct current magnetron sputtering. NH 4 F/ethylene glycol electrolyte was used to demonstrate the growth of stable nanotubes at room temperature. Ti…
Among multiple interconnected pathways for l-Lysine catabolism in pseudomonads, it has been reported that Pseudomonas aeruginosa PAO1 employs the decarboxylase and the transaminase pathways. However, up until now, knowledge of several genes involved in operation and regulation of these pathways was still missing. Tran…
Focusing on the interface effect of the Ni80Fe20 (Py)/terbium (Tb) bilayer, the influence of interface on the magnetization dynamic damping is investigated systematically. Two series of Py (12 nm)/Tb (d nm) films with and without copper (Cu) (1 nm) interlayer are deposited on silicon (Si) substrates by DC magnetron sp…
The problem of plane wave diffraction from the periodic structure of an infinite PEC wall lined with pyramidal absorbers is considered. A hybrid method based on the R-matrix Fourier modal method (RFMM) and the mode matching (MM) of fields is used for the efficient and robust analysis of this class of absorbers. The hy…
Abstract N‐terminal verkürzte, Pyroglutamat‐modifizierte Varianten des Aβ‐Peptids sind natürlich vorkommende chemische Modifikationen bei der Alzheimerschen Krankheit. Wir zeigen hier, dass die beiden Modifikationen die Länge der Fibrillen und den Übergangsmittelpunkt der thermischen Entfaltung der Fibrillen signifika…
The existence of a critical thickness at which the optical reflectance of a polymer-filler composite reaches its maximum value is demonstrated and its dependence on back reflection of the substrate, filler volume fraction, filler size, as well as the matrix-filler refractive indices difference is elucidated. The analy…
The oral administration of hyaluronans (HAs) (molecular weight, 300k and less than 10k) to photoaged hairless mice increased the moisture content of the stratum corneum and decreased the epidermal thickness, respectively. Furthermore, orally administered HAs suppressed the low-molecular weight of HA content of the ski…
We investigate ultrathin highly ordered layers of tin(II)-phthalocyanine (SnPc) on top of a monolayer (ML) of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) on Ag(111). The films are analyzed structurally by means of scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED) as well as optica…
The clotting protein von Willebrand factor (VWF) binds to platelet receptor glycoprotein Ibα (GPIbα) when VWF is activated by chemicals, high shear stress, or immobilization onto surfaces. Activation of VWF by surface immobilization is an important problem in the failure of cardiovascular implants, but is poorly under…
The shock-induced serine protease HtrA1 is a potential regulator of human placenta development during pregnancy. The protein contains a functional PDZ domain that has been solved in complex with a phage display-derived heptapeptide: Asp-6 Ser-5 Arg-4 Ile-3 Trp-2 Trp-1 Val0 . In this study, a rationally designed haloge…
This work presents a heat transport benchmark problem when modeling the steady-state radial conduction in a fuel rod coupled to the axial heat convection in a coolant surrounding the rod and flowing along it. This benchmark problem admits exact analytical solutions for the spatially dependent temperature distributions…
Abstract The grain orientation, the texture and the grain boundary misorientations are important parameters for the understanding of the magnetic properties of the bulk MgB 2 samples intended for super-magnet applications. Such data can be provided by electron backscatter diffraction (EBSD) analysis. However, as the g…
Abstract In this article, a systematic method based on two sensory experiments has been proposed to explore the relations between the visual and haptic perceptions of the tactile properties of a number of textile samples. The first experiment is designed to investigate to what extent fabric tactile properties could be…
One-dimensional titanate nanotubes (TiONTs) were subjected to systematic ion exchange to determine the impact of these modifications on biological activities. Ion exchanged TiONTs (with Ag, Mg, Bi, Sb, Ca, K, Sr, Fe, and Cu ions) were successfully synthesized and the presence of the substituted ions was verified by en…
Chalcogen and pnicogen bond interactions are studied in the binary XHS:PH2X complexes (X = F, Cl, CCH, COH, CH3, OH, OCH3 and NH2) using quantum chemical calculations. These interactions can be explained in terms of electrostatic effects, considering the chalcogen or pnicogen as a Lewis acid due to the presence of an…
The dependence of perpendicular magnetization and Curie temperature (Tc) of Pt/Co/Pt thin films on the thicknesses of Pt seed (Pts) and presence of Ta buffer layer has been investigated in this work. Pt and Co thicknesses were varied between 2 to 8 nm and 0.35 to 1.31 nm (across the spin reorientation transition thick…
