Molecular dynamics analyses were performed to examine conformational changes in the C-domain of calmodulin and the N-domain of troponin C induced by binding of Ca(2+) ions. Analyses of conformational changes in calmodulin and troponin C indicated that the shortening of the distance between Ca(2+) ions and Ca(2+) binding sites of helices caused widening of(More)
The ClC chloride channels control the ionic composition of the cytoplasm and the volume of cells, and regulate electrical excitability. Recently, it has been proposed that prokaryotic ClC channels are H+-Cl- exchange transporter. Although X-ray and molecular dynamics (MD) studies of bacterial ClC channels have investigated the filter open-close and ion(More)
Enclosed please find the original Word files of a new paper entitled " The atomic-level mechanism underlying the functionality of aquaporin-0 ". So far, more than 82,000 protein structures have been reported in the Protein Data Bank, but the driving force and structures that allow for protein functions have not been elucidated at the atomic level for even(More)
A 23-year-old man was admitted to our hospital because of cough and sputum in April 2001. A chest roentgenogram revealed infiltrative shadow with cavity formation in the bilateral lung fields. He was treated with sensitive antituberculous drugs. After starting the antituberculous therapy with INH, RFP, EB and PZA, bilateral cervical lymphadenopathy(More)
A 20-year-old woman was admitted to our hospital because of cough and dyspnea in April 2001. On admission, laboratory data showed positive inflammatory signs. A chest roentogenogram revealed infiltrated shadow in the bilateral lung fields. Sputum smear examination showed acid-fast bacilli identified as Mycobacterium tuberculosis by DNA-DNA PCR method. Four(More)
By using a piezoelectric sensor, it was demonstrated that the visual evoked potential of a rat brain was accompanied by mechanical movements of the brain when it was excited. A phase of upward movement was found to be followed by a phase of downward movement. The largest upward movement was a rise in swelling pressure on the order of 100 µg, which was about(More)
