Raman scattering of molecular oxygen in the region of the Schumann–Runge absorption band system is calculated from first principles in the second order of perturbation theory in the interaction of photon–electron operator. Quantitative predictions are given for the cross sections for scattering of photons and a detailed comparison is made with available measurements. The behavior of Raman spect...

Physiol. 273 (Cell Physiol. 42): C2010–C2021, 1997.—The patch-clamp technique was used to determine the ionic conductances activated by ATP in murine colonic smooth muscle cells. Extracellular ATP, UTP, and 2-methylthioadenosine 58-triphosphate (2-MeSAT...

Rapid and differential diagnosis of highly pathogenic avian influenza virus (HPAIV) subtype H5 is essential for the effective prevention and control of outbreaks caused by this pathogen. In this study, we describe a one-step multiplex real-time reverse transcription polymerase chain reaction (mRRT-PCR), using H5-, N1-, and N8-specific primers and probes, for differential detection of two HPAIVs...

PURPOSE To evaluate the effect of the iPad as a low vision aid in improving the reading ability of low vision patients (LVPs). METHODS In this study, 228 consecutive patients that came for their routine eye care examination at the University of Florida, Jacksonville eye clinic, were enrolled. Patients met inclusion criteria if they had best-corrected visual acuity (BCVA) of 20/100 or worse in...

Overexpression of the BltD gene in Bacillus subtilis causes acetylation of the polyamines spermidine and spermine. BltD is co-regulated with another gene, Blt, which encodes a multidrug export protein whose overexpression facilitates spermidine export [Woolridge, Vazquez-Laslop, Markham, Chevalier, Gerner and Neyfakh (1997) J. Biol. Chem. 272, 8864-8866]. Here we show that BltD acetylates both ...

The transplantation of human cancer cells into immunodeficient NOD/SCID/IL-2Rγc(null) (NOG) mice often causes highly malignant cell populations like cancer stem cells to emerge. Here, by serial transplantation in NOG mice, we established two highly tumorigenic adult T-cell leukemia-derived cell lines, ST1-N6 and TL-Om1-N8. When transplanted s.c., these cells formed tumors significantly earlier ...

Unno, Naoki, Shozo Baba, and Mitchell P. Fink. Cytosolic ionized Ca21 modulates chemical hypoxia-induced hyperpermeability in intestinal epithelial monolayers. Am. J. Physiol. 274 (Gastrointest. Liver Physiol. 37): G700–G708, 1998.—We reported previously that ATP depletion induced by glycolytic inhibition or cellular hypoxia increases the permeability of intestinal epithelial monolayers [N. Unn...

A series of new N4 and N8 macrocycles has been prepared, that includes cis-exogenous O2, S2 and S/O atoms to allow chelation to a metal external to the macrocyclic ring. We found that thioamide units within the macrocycles were unstable to attack by secondary amines and thus alkylated precursors containing only tertiary amines could lead to exogenous-S2 macrocycles. Cyclisation of alkylated tet...
