amphibians have a large variety of antimicrobial peptides that serve as natural innate barriers limiting microbial infection or, in some instances, act as an integral component in response to inflammation or microbial infection. a novel peptide with antibacterial effects and without hemolytic activity was purified from skin secretions of rana ridibunda by multisteps cation-exchange fplc, revers...

INTRODUCTION We directly measured diagnostic X-ray photon spectra produced by a single-phase 2-pulse diagnostic X-ray unit driven at 50 to 100 kV and a few mA(1), a mammographic X-ray unit at 25 to 32 kV and 3 times of 80 mAs(2) and an X-ray computed tomography (CT) scanner at 120 kV and 3 mA(3) have been analyzed. Since detected spectra were distorted by the response of CdZnTe(CZT) detector an...

The benzene and benzene dimer cations are studied using the equation-of-motion coupled-cluster model with single and double substitutions for ionized systems. The ten lowest electronic states of the dimer at t-shaped, sandwich, and displaced sandwich configurations are described and cataloged based on the character of the constituent fragment molecular orbitals. The character of the states, bon...

Time-resolved two-dimensional (2D) electronic spectra (ES) tracking the evolution of the excited state manifolds of the retinal chromophore have been simulated along the photoisomerization pathway in bovine rhodopsin, using a state-of-the-art hybrid QM/MM approach based on multiconfigurational methods. Simulations of broadband 2D spectra provide a useful picture of the overall detectable 2D sig...
