We evaluated the effects of increasing the viscosity (eta) in peritubular capillary perfusates (PCP; 20 mM HNaPO4--Ringer, pH 7.4) on proximal convoluted tubule (PCT) acidification. Micropuncture experiments were performed with simultaneous luminal and peritubular perfusion. Changes in pH of a 20 mM HNaPO4--Ringer (pH 7.4 at t = 0) droplet placed in PCT lumen were measured with H+-sensitive mic...
The magnetic field effects (MFEs), caused by the Delta g mechanism, on the photoinduced hydrogen abstraction reaction of benzopheneone with thiophenol were investigated in alcoholic solutions of varying viscosities (eta = 0.55 to 59.2 cP) by a nanosecond laser flash photolysis technique. The escape yield of benzophenone ketyl radicals ( Y) gradually decreased with increasing magnetic field stre...
The use of cell-penetrating peptides (CPPs), such as polyarginine, has been shown to facilitate the import of drugs and other cargos into cells. However, a major obstacle limiting their use as delivery agents is their entrapment following internalization into endocytic vesicles, leading to either their recycling out of cells or their degradation in lysosomes. To address this challenge, we fused...
Mutations at A/T bases within immunoglobulin genes have been shown to be generated by a repair pathway involving the DNA-binding moiety of the mismatch repair complex constituted by the MSH2-MSH6 proteins, together with DNA polymerase eta (pol eta). However, residual A/T mutagenesis is still observed upon inactivation in the mouse of each of these factors, suggesting that the panel of activitie...
Glutamic acid-553 of Pseudomonas aeruginosa exotoxin A (ETA), identified previously as an active-site residue, was deleted by oligonucleotide-directed mutagenesis of the cloned toxin gene in Escherichia coli. The purified mutant toxin was stable, fully immunoreactive, and capable of blocking toxin receptors. ADP-ribosyltransferase and cytotoxic activities were at least 10(6)-fold lower than tho...
A measurement of two-particle correlations with a high transverse momentum trigger particle (p(T)(trig) > 2.5 GeV/c) is presented for Au+Au collisions at square root(s(NN)) = 200 GeV over the uniquely broad longitudinal acceptance of the PHOBOS detector (-4 < Delta eta < 2). A broadening of the away-side azimuthal correlation compared to elementary collisions is observed at all Delta eta. As in...
We investigated the alterations of major fatty acid components in epidermis by natural aging and photoaging processes, and by acute ultraviolet (UV) irradiation in human skin. Interestingly, we found that 11,14,17-eicosatrienoic acid (ETA), which is one of the omega-3 polyunsaturated acids, was significantly increased in photoaged human epidermis in vivo and also in the acutely UV-irradiated hu...
Reactions of copper(I) halides with imidazolidine-2-thione and 1-methyl-1,3-imidazoline-2-thione in dmso involved C-S rupture in aerobic conditions and yielded a sulfate bridged polymer, [Cu(II){eta(2)-N,N-(N(2)C(3)H(5))(2)S}(mu-O,OSO(2))(eta(1)-OH(2))](n) 1 and a sulfate chelated monomer, [Cu(II){eta(2)-N,N-(N(2)C(4)H(5))(2)S}(eta(2)-O,OSO(2))(eta(1)-OH(2))] 2 {N,N-(N(2)C(3)H(5))(2)S = 2,2'-th...
We study copper corrosion inhibition by ethanolamine (ETA)with (0, 0.2 ,0.3,0.4,0.5) vol.% concentrations in 100 ppm NaCl solution. This work is carried out by potentiodynamic measurements and Electrochemical Impedance Spectroscopy (EIS). The substrates' surface morphologies are examined by Scanning Electron Microscopy (...
Background: Recent research has provided evidences indicating the importance of endothelin axis in carcinogenesis. According to our knowledge, there are little information about endothelin A receptor (ETA) expression in oral squamous cell carcinoma (OSCC). So, the aim of the present study was to evaluate the immunohistochemical expression of ETA in OSCC and normal oral mucosa (...
