This review deals with the role of carboxylic amino acids in the proton transport activity of bacteriorhodopsin. The main focus is on the infrared data, which allow direct monitoring of the protonation/deprotonation of specific residues dur ing the proton movement in the course of the photocycle. Additional attention is paid to the potential use of carboxylic acids in proteins as internal senso...

The volatile constituents of the aerial parts of Carum montanum (Coss. et Dur.) Benth. et Hook. were analysed by GC-FID and GC-MS, and the main component was isolated and identified as nothoapiole. The antibacterial and antifungal activities of this compound and of the total oil were investigated against Gram-negative (P. aeruginosa, E. coli), Gram-positive (E. faecalis, S. aureus, S. epidermit...

Dur ing the last few years, development in upper l imb prosthetics has been focused on the use of external power. N o w the introduction of the endoskeletal structure of body-powered a rm prostheses requires completely new develop­ ments of such traditionally established designs as the mechanical elbow joint . The s tandard exoskeletal elbow requires for operat ion two control movements, one fo...

Owing to lack of multiple components prompt $\gamma$-ray emissions in short gamma-ray bursts (sGRBs), how these distinct are correlated still keeps unclear. In this paper, we investigate the spectral and temporal properties precursors, main peaks extended 26 sGRBs including GRB 170817A. It is found that peak energies ($E_p$) each pulse uncorrelated with duration ($t_{dur}$). Meanwhile, find the...

BACKGROUND/AIMS Intranasal mupirocin and chlorhexidine bathing are candidate strategies to prevent healthcare-associated infections caused by methicillin-resistant Staphylococcus aureus (MRSA). In Korea, intranasal mupirocin is not available, and mupirocin ointment, an over-the-counter drug, has been used indiscriminately. Furthermore, because it is covered by health insurance, mupirocin is eas...

BACKGROUND There is considerable disagreement over the effects of percutaneous coronary intervention (PCI) on left ventricular diastolic function that has necessitated the investigation of diastolic indices. The present study was conducted to evaluate left ventricular diastolic function and its indices, three months after performing the PCI procedure in patients with coronary artery disease (CA...

Late potentials have been reported to be affected by body size or left ventricular mass. To our knowledge, however, the effect of subadipose tissue, which is known to influence QRS amplitudes of the surface ECG on the variables of late potentials, has not been evaluated. The relationships between the variables of late potentials and various obesity indices were assessed in 45 men, aged 24 to 38...
