In this paper we present proton spin-lattice ( T} ) and spin-spin ( T2) relaxation times meas­ ured vs. concentration, temperature, pulse interval (xCpmg) as well as 'H NMR spectral measurements in a wide range of concentrations of bovine serum albumin (BSA ) solutions. The anomalous relaxation behaviour of the water protons, similar to that observed in mam­ malian lenses, was found in the two ...

The total cross section for the near threshold η production in proton-proton collisions has been investigated with the assumption that the production mechanism is due to the emission of a meson x(π, η, σ) from one of the nucleons followed by a xN → ηN transition on the second one. The xN → ηN amplitudes are generated from the unitary multi-channel multi-resonance model which has recently been c...

The objective was to study the effect of phosphate salts and fixation solutions on the proton dynamics in articular cartilage in vitro. Microscopic magnetic resonance imaging (μMRI) T(2) anisotropy and nuclear magnetic resonance (NMR) double quantum-filtered (DQF) spectroscopy were used to study the full-thickness articular cartilage from several canine humeral heads. The in-plane pixel size ac...

Proton transfer reactions are one of the most fundamental processes in biochemistry. We present a simplistic approach for estimating proton probabilities membrane protein, cytochrome c oxidase. combine short molecular dynamics simulations at discrete protonation states with Monte Carlo to exchange between those states. Requesting existence hydrogen-bonded connection two source and target residu...

Dual M-Z interferometer is the sensitive element of three-component acceleration seismic geophone, while Y branch waveguide is the basic optical components composed of dual M-Z interferometer, so the design of Y branch waveguide directly affects the performance of threecomponent acceleration seismic geophone. Firstly, branch waveguide and S-shaped bent waveguide are introduced, and symmetrical ...

The tyrosine decarboxylase operon of Lactobacillus brevis IOEB9809 contains, adjacent to the tyrosine decarboxylase gene, a gene for TyrP, a putative tyrosine transporter. The two genes potentially form a proton motive tyrosine decarboxylation pathway. The putative tyrosine transporter gene of L. brevis was expressed in Lactococcus lactis and functionally characterized using right-side-out memb...
