Epitaxial chemical vapor deposition (CVD) growth of uniform single-layer graphene is demonstrated over Co film crystallized on c-plane sapphire. The single crystalline realized the sapphire substrate by optimized high-temperature sputtering and successive H2 annealing. This enables formation graphene, while a polycrystalline deposited SiO2/Si gives number flakes with various thicknesses. Moreover, an epitaxial relationship between as-grown lattice observed when synthesis occurs at 1000 °C;...
Adenosine A2A receptors are abundant in the caudate-putamen and involved motor control several species. In MPTP-treated monkeys, receptor-blockade with an antagonist alleviates parkinsonian symptoms without provoking dyskinesia, suggesting this receptor may offer a new target for antisymptomatic therapy of Parkinson's disease. present study, significant neuroprotective effect antagonists is shown experimental models Oral administration protected against loss nigral dopaminergic neuronal...
Size, orientation, and boundary of graphene domains are the current focus chemical vapor deposition (CVD) growth because they closely related to graphene's physical properties. Here, we study domain structure single-layer grown by ambient pressure CVD over heteroepitaxial Cu(111) Cu(100) films. Low energy electron microscope measurements reveal that film gives uniform whose orientation is consistent with underlying Cu lattice for areas 1 mm2. On other hand, on exhibits clear multidomain two...
A nationwide survey on Hirschsprung's disease was conducted to clarify the recent trends of diagnosis and treatment seen in Japan from 1978 1982. total number 1628 cases were collected 135 medical institutions. Estimated incidence 1/4697. In diagnosis, anorectal manometry carried out 64.7% patients histochemistry 28.7%. Barium enema with most frequently used combination methods. 48.7% diagnosed first month life. The overall rate creation colostomy 61.3% aganglionosis extended sigmoid colon....
In the course of continuing efforts to develop potent and bladder-selective muscarinic M3 receptor antagonists, quinuclidin-3-yl 1-aryl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate derivatives related compounds were designed as conformationally restricted analogues benzhydrylcarbamate (8). Binding assays with rat subtypes revealed that showed high affinities for receptor, selectivity over M2 receptor. Of these derivatives, (+)-(1S,3'R)-quinuclidin-3'-yl...
Decreased E-cadherin expression in tumor cells has been suggested to promote invasiveness. We examined 30 cases of endometrial carcinoma by immunohistochemistry using a monoclonal antibody and investigated its correlation with other histopathologic features the tumor. observed that: (1) decreased loss differentiation (P < 0.05); (2) was inversely correlated depth myometrial invasion (3) paraaortic node metastasis 0.01); (4) multivariate analysis comparing pattern expression, histologic...
Dopamine (DA), which is ineffective by oral administration due to first pass metabolism and usually injected, was administered dogs via rectal, dermal, buccal nasal routes. The route had the highest bioavailability best avoided metabolism. effects of addition hydroxypropyl cellulose (HPC), sodium deoxycholate, POE (6) hydrogenated caster oil (HCO-60) Azone on absorption increased from 11.7% (control) about 20%, 35%, 25% 68%, respectively.Further, with a combination 2%HPC 5%Azone, almost same...

The solubility, diffusivity, and permselectivity of propylene propane in 40 different polyimides synthesized from 2,2-bis(3,4-decarboxyphenyl)hexafluoropropane dianhydride (6FDA) were determined at 298 K. influence the chemical structures on physical gas permeation properties 6FDA-based was studied. solubility an unrelaxed volume a polymer matrix mainly contributes to total for various polyimides. permeability propylene, propylene/propane mixed-gas system depend propylene. This is thought be...
As a further approach to an understanding of relationship between the magnitudes micellar solubilization and hydrophobicities solubilizates, steroid hormones (19 species) were selected explore meaning intercept b value. Two linear free energy relationships established aqueous-polyoxyethylene lauryl ether partition coefficient (K) (Poctanol) aqueous solution n-octanol. One consisted steroids carrying fluorine atom at carbon 9 other those no atom. The value predicted that are solubilized in...
A 14-year-old girl with numerous café-au-lait spots in her skin was hospitalized because of fever, weight loss, and a mass the right upper quadrant abdomen. Despite intensive chemotherapy, she died 6 months after admission. The autopsy revealed adrenal tumor metastases to liver, lungs, vertebrae, lymph nodes. Histologically pheochromocytoma small foci ganglioneuroblastoma. catecholamine contents were markedly elevated, as confirmed by fluorescence technique. Electron microscopically, cells...
The interaction of tranquilizing drugs phenothiazines with β-cyclodextrin in aqueous solution was studied by circular dichroism, ultraviolet (UV) absorption, and proton magnetic resonance spectroscopies. induced dichroism bands UV absorption changes were quantitatively investigated stoichiometric ratio, which found to be 1 : 1, formation constants inclusion complexes obtained. In β-cyclodextrin-drug system, protons located a cavity subjected anisotropic shielding, while phenyl N-substituted...
Abstract Recently, experiments on basic plasma physics issues for solving future problems in fusion energy have been performed a Large Helical Device. There are several to be solved devices energy. Emerging burning are: alpha-channeling (ion heating by alpha particles), turbulence and transport electron dominant helium ash exhaust, reduction of the divertor heat load. To solve these problems, understanding (1) wave–particle interaction through (inverse) Landau damping, (2) characteristics...
