bstract —Large aspiny (LA) neurons in the neostriatum are esistant to cerebral ischemia whereas spiny neurons are ighly vulnerable to the same insult. Excitotoxicity has been mplicated as the major cause of neuronal damage after ischmia. Voltage-dependent potassium currents play important oles in controlling neuronal excitability and therefore influnce the ischemic outcome. To reveal the ionic ...

In this study, the p-type Ga-doped Cu3Sb1−xGaxSe4 compounds were fabricated by melting, annealing, grinding, and spark plasma sintering (SPS). The transport properties of Ga-doped Cu3Sb1−xGaxSe4 compounds were investigated. As Ga content increased, the hole concentration of Cu3Sb1−xGaxSe4 compounds increased, which led to an increase in electrical conductivity. Meanwhile, the Seebeck coefficien...

Type 2 diabetes mellitus (T2DM) is strongly associated with obesity. The adipose tissue secretes bioactive adipokines leading to low grade inflammation, amplified by oxidative stress, which promotes the formation of advanced glycation end products and eventually leads to dyslipidemia and vascular complications. The aim of this study was to correlate anthropometric, biochemical and oxidative str...

This paper presents the results of a study of resonantly enhanced, three-, photon absorption in Nd-doped yttrium aluminum garnet (Y3Alg0~2) or Nd: YAG. The trivalent ions of the rare-earth elements, such as Nd'+, are characterized by energy levels which remain relatively sharp even in a crystalline environment, and thus crystalline solids doped with rare-earth ions present interesting systems i...

The photoablative products from human cadaver corneas treated with lasers were investigated using gas chromatography and mass spectroscopy. The photoablations were done separately with an excimer laser (193 nm) and with an erbium: yttrium aluminum garnet (Er:YAG) laser (2.94 microns). More than 20 different types of molecules with a molecular weight of 40-400 mass units could be identified, mos...

The electron-phonon coupling in iron-doped yttrium aluminum garnet crystals is studied in the theoretical framework of linear and quadratic coupling. The line shift and line broadening of the zero phonon line of iron centers as a function of temperature between 10 and 150 K is qualitatively and quantitatively explained. The spectroscopic features of the line, deduced from the theory of lattice ...

We report the fabrication and characterization of segmented element power generator modules of 16 x 16 thermoelectric elements consisting of 0.8 mm thick Bi2Te3 and 50 μm thick ErAs:(InGaAs)1-x(InAlAs)x with 0.6% ErAs by volume. Erbium Arsenide metallic nanoparticles are incorporated to create scattering centers for middle and long wavelength phonons, and to form local potential barriers for el...

Using immunoradiometric assays (IRMAs) from Hybritech Inc. (H) and Nichols Institute Diagnostics (ND), we measured somatotropin (human growth hormone, hGH) in serum samples obtained every 20 min for 24 h from 10 prepubertal subjects with short stature. Results obtained with the ND reagents were 2.74 times greater than those obtained with the H reagents (P = 0.00001, r = 0.94, SEE = 3.9, n = 720...
