Helix 8 of the M1 muscarinic acetylcholine receptor: scanning mutagenesis delineates a G protein recognition site.
We have used alanine-scanning mutagenesis followed by functional expression and molecular modeling to analyze the roles of the 14 residues, Asn422 to Cys435, C-terminal to transmembrane (TM) helix 7 of the M(1) muscarinic acetylcholine receptor. The results suggest that they form an eighth (H8) helix, associated with the cytoplasmic surface of the cell membrane in the active state of the recept...
متن کاملDetermination of 8-methoxypsoralen in plasma by scanning fluorometry after thin-layer chromatography.
A rapid and sensitive method is described for determining 8-methoxypsoralen in plasma. Plasma samples are acidified with 6 mol/liter and heated in a boiling water bath to release the plasma-bound drug nondestructively. It then is extracted into a solvent mixture consisting of benzene/ethyl acetate (9/1 by vol). The solvent phase is separated, evaporated, and an aliquot of the dissolved residue ...
متن کاملThree-dimensional anatomy of the 8-day mouse concepts: a study by scanning electron microscopy.
The three-dimensional anatomy of the 8-day mouse concepts was studied by scanning electron microscopy aided by microdissection within the microscope specimen chamber. Attention was given to the relationship of the extra-embryonic membranes and their subtended compartments and particular emphasis was placed on the 'inverted' condition of the embryo at this stage of development. The main points b...
متن کاملReverse Product-Scanning Multiplication and Squaring on 8-Bit AVR Processors
High performance, small code size, and good scalability are important requirements for software implementations of multi-precision arithmetic algorithms to fit resource-limited embedded systems. In this paper, we describe optimization techniques to speed up multi-precision multiplication and squaring on the AVR ATmega series of 8-bit microcontrollers. First, we present a new approach to perform...
متن کاملINTRATHORACIC KIDNEY: A CT-SCANNING VIEW
We report a patient who was admitted to the department of medicine with palpitation, dyspnea and left flank pain, Chest X-ray revealed a mass in the left lung. The lesion was evaluated as a pulmonary tumor, with a high suspicion of malignancy. Intravenous urography, sonography, and CTscanning revealed a thoracic kidney at the location previously thought to be a lung mass. This is the firs...
