Background and Purpose We examined whether hemodynamic metabolic abnormalities in the cerebral white matter, basal ganglia, thalamus are associated with asymptomatic matter lesions (WML) depicted on MR images. Methods A positron emission tomographic study H 2 15 O, C O was performed eight normal control subjects without any WML (mean±1 SD age, 68.5±10.2 years) (71.3±8.5 to measure regional blood flow (CBF), volume, oxygen extraction fraction (OEF), rate. Results In WML, significantly lower...
The purpose of this work is to study a DC reactor type fault current limiter (FCL) using high temperature superconducting (HTS) coil which connected with the secondary winding transformer through diode bridge. superconductors provide advantages higher operation and they are preferably applied limiters, where can be operated at both low voltage current. authors propose three-phase FCL incorporating only one HTS present its test result. A for 6.6 kV-2000 requires 2.9 MJ.
[123I]Iomazenil is a single-photon emission computed tomography (SPECT) tracer that selectively binds to central benzodiazepine receptor in the neuron membrane. With this ligand, we studied distribution cortex remote from subcortical hematoma intracerebral hemorrhage patients.Four patients with unilateral putaminal and one patient right thalamic were (mean +/- 1 SD age, 50.0 8.8 years). The initial volume of ranged 4.3 31.0 mL SD, 17.5 12.3 mL). SPECT images obtained 3 hours after...
Abstract Chemically modified cellulose microbeads are useful as cosmetic materials. Cellulose supports, prepared by a viscose‐phase‐separation method, monodisperse and spherical. However, shows only slight hydrophilicity, even though it has three hydroxyl groups per pyranose ring, because possesses high crystallinity on account of the II structure derived from hydrogen bonds among groups. To increase hygroscopicity microbeads, we have carboxylated them with succinic glutaric anhydrides....
A new family of self-assembling systems based on nucleoamphiphiles is described. Nano to micrometric left-handed helix formation in aqueous solution was induced simply by complexing a GMP or an AMP with nonchiral monocationic amphiphile. The assembling behavior such as micellar formation, monolayer at air-water interface, well the aggregates these are strongly influenced presence nucleosides solution. observed effects depend properties complexed nucleotides and complex mixture pi stacking,...
Let Σg,1 be a compact oriented surface of genus g with one boundary component, and ℳg,1 its mapping class group. Morita showed that the image kth Johnson homomorphism τkℳ is contained in kernel hg,1(k) an Sp–equivariant surjective H⊗ℤℒ2g(k+1)→ℒ2g(k+2), where H:=H1(Σg,1,ℤ) ℒ2g(k) degree k part free Lie algebra ℒ2g generated by H.

In this paper we construct new obstructions for the surjectivity of Johnson homomorphism automorphism group a free group. We also determine structure cokernel degrees 2 and 3.
Abstract Ampholyte monomers with zwitterionic moiety derived from α‐amino acid, that is, L‐lysine and L‐serine, were obtained using a method in which their copper complexes could be produced simple steps. The N‐acryloylation of L‐serine was carried out by reaction between acryloyl chloride. Specifically, the removal complex amino acid through use 8‐hydroxyquinoline as an organic chelate precipitant increased yield ampholyte moiety. These syntheses easily three‐step procedure. Keywords: Amino...
We propose a single DC reactor type fault current limiter. This limiter is for three-phase power system, employing only one superconducting coil that connected with the secondary windings of transformers through diode-bridge. In this composition, using high temperature takes advantage inductance and does not require normal transition. paper presents most suitable case 6.6 kV system compares it three reactors
In this paper, we determine the cokernel of $k$-th Johnson homomorphisms automorphism group a free metabelian for $k \geq 2$ and $n 4$. As corollary, obtain lower bound on rank graded quotient filtration group. Furthermore, by using second homomorphism, image cup product map in rational cohomology IA-automorphism group, show that it is isomorphic to which already determined Pettet. Finally, considering kernel Magnus representations there are non-trivial classes not map.
Anionic nucleotides adenosine monophosphate or guanosine interact with cationic vesicles, exchange the counteranions of amphiphiles in situ, and organize themselves at membrane surfaces. Such organized reciprocally transfer their chirality to membranes nonchiral induce formation right-handed micrometric helices on time scale hours. The kinetics nucleotide molecular organization supramolecular was followed. We have shown that helix is a kinetic-dependent process does not primarily result from...

The pathogenesis of non-alcoholic steatohepatitis (NASH) involves the simultaneous interaction multiple factors such as lipid accumulation, oxidative stress, and inflammatory response. Here, effect human serum albumin (HSA) fused to thioredoxin (Trx) on NASH was investigated. Trx is known have anti-oxidative, anti-inflammatory, anti-apoptotic effects. However, a low molecular weight protein rapidly eliminated from blood. To overcome availability Trx, HSA-Trx fusion produced evaluated...
