Fractions rich in Golgi apparatus were isolated from female rat liver and incubated with different concentrations of MgATP and calcium. Calcium was sequestered by the fraction in the presence but not in the absence of ATP. The kinetics of the uptake process showed an exponential type accumulation to a maximum value which could be explained by a 'pumpleak' mechanism where Vmax was estimated at 6...

Using a low power beam of ultrashort THz pulses that propagate in the ambient laboratory environment we have measured the rotational signatures of small molecule vapors at frequencies within the atmospheric transmission windows. We investigate two types of apparatus. In the first type the THz beam propagates along a 6.7 meter round trip path that is external to the spectrometer, and which conta...

This report summarizes some trends observed in drug dissolution testing, based upon the United States Pharmacopeia (USP) dissolution Apparatus Suitability Test results and the preliminary data obtained from an international collaborative study to assess the pharmaceutical quality of furosemide products in different countries. Based on the USP calibrator data submitted by the participants, repre...

We investigate cancellation of spatial aberrations induced by an object placed in a quantum coincidence interferometer with type-II parametric down conversion as a light source. We analyze in detail the physical mechanism by which the cancellation occurs and show that the aberration cancels only when the object resides in one particular plane within the apparatus. In addition, we show that for ...

Leukotriene B4 receptor type 2 (BLT2) is a G protein-coupled (GPCR) mainly expressed in epithelial cells, where it enhances barrier function. A unique characteristic of BLT2 its restricted localization to the lateral membrane. However, molecular mechanism underlying membrane and physiological roles laterally localized are unknown. BLT1 most homologous GPCR localizes both apical membranes. In th...

Congenital mitral ring is a rare type of congenital mitral stenosis. There are two types of mitral ring: the intramitral ring and the supramitral ring. Intramitral rings are often associated with complex valve pathology, and therefore have a worse prognosis than supramitral rings, in which the mitral apparatus is usually normal. The role of echocardiography in the evaluation of the mitral valve...

We report here a multiple-reflection type ultra-small-angle x-ray-scattering apparatus constructed according to the principle proposed by Bonse and Hart. The ultra-small-angle x-ray scattering technique enables us to investigate the distribution of solutes or particles in turbid systems, which could not be studied by the conventional light-scattering and microscopic methods. By this method, the...

Fibers’ splicing is one of the essential and critical procedures for fiber optics and photonics devices, modules and networks. The purpose of this paper is to present a recommended apparatus which allows reducing the frequency to clean the electrodes of the fusion – splicer equipment when Corning’s erbium doped fibers are spliced together or to other type of all-silica fibers. Also, this recomm...
