Measurements of water vapor absorption coefficients for 27 CO/sup 2/ laser lines are given. Some measurements were obtained using a spectrophone and others using a long path absorption cell. Measurements were made with pure water vapor, and with samples broadened with N/sup 2/ and with O/sup 2/-N/sup 2/ mixtures. This is discussed in ...

We investigated the role of cellular calcium pools in angiotensin II-stimulated aldosterone synthesis in bovine adrenal glomerulosa cells. Angiotensin II decreased the size of the exchangeable cell calcium pool by 34%, consistent with previous observations that angiotensin II causes decreased ...
Isolated mesophyll cells and bundle sheath cells of Digitaria sanguinalis were used to study the light-absorbing pigments and electron transport reactions of a plant which possesses the C(4)-dicarboxylic acid cycle of photosynthesis. Absorption spectra and chlorophyll determinations are presented showing that mesophyll ...

In this work, a neutral iridium(III) complex [Ir(bt)(2)(acac)] (Hbt = 2-phenylbenzothiazole; Hacac = acetylacetone) has been realized as a Hg(II)-selective sensor through UV-vis absorption, phosphorescence emission, and electrochemical measurements and was further developed as a phosphorescent agent for monitoring intracellular Hg(II). ...
In this study, we report on an in�situ monitoring system of living cultured cells using infrared absorption spectroscopy in the geometry of multiple internal reflections (MIR-IRAS). In order to observe living cultured cells, the temperature in the sample chamber of a FT-IR spectrometer was maintained at 37��C and a humidified gas ...
The SUNSPOT code for the analysis of direct gain solar heated buildings has been expanded to allow for either a coarse (Level I) or detailed (Level II) description of interior geometry. The more detailed Level II model was recently completed and validated against test cell data obtained at the LASL solar laboratory. The effect on ...
A system and method for detecting a detectably labeled cell or component thereof in a sample comprising one or more cells or components thereof, at least one cell or component thereof of which is detectably labeled with at least two detectable labels. In one embodiment, the method comprises: (i) introducing the sample into one or more ...
Scrubbing of NO(x) from the gas phase with Fe(II)EDTA has been shown to be highly effective. A new biological method can be used to convert NO to N(2) and regenerate the chelating agent Fe(II)EDTA for continuous NO absorption. The core of this biological regeneration is how to effectively simultaneous reduce Fe(III)EDTA and ...

The intestinal absorptive characteristics and the efflux mechanisms of candesartan (CDS), a novel angiotensin II type 1 receptor blocker, were investigated. The Caco-2 cells were used as models of the intestinal mucosa to assess uptake and transport of CDS. The determination of CDS was performed by HPLC-Flu. In the Caco-2 ...

Previously performed studies have shown that Pseudomonas putida CZ1 biomass can bind an appreciable amount of Cu(II) and Zn(II) ions from aqueous solutions. The mechanisms of Cu- and Zn-binding by P. putida CZ1 were ascertained by chemical modifications of the biomass followed by Fourier transform infrared and X-ray absorption ...
