DE protection, demineralization, de colorization, and acetylation. Protein accesses were used to obtain chitosan from shrimp shell waste. Using FTIR, SEM XRD. It was characterized. Also analyzed the physiochemical parameter such as moisture content, hydrogen meter, viscosity, degree of acetylation solubility The age bacterial culture influenced its susceptibility with cells being most prone in ...

We addressed the evolutionary trace of hetero-oligomer interfaces by comparing the structures of paralogous proteins; one of them is a monomer or homo-oligomer and the other is a hetero-oligomer. We found different trends in amino acid conservation pattern and hydrophobicity between homo-oligomer and hetero-oligomer. The degree of amino acid conservation in the interface of homo-oligomer has no...

In this article, we describe further studies toward the originally proposed structure of diazonamide A (1). After confronting a number of failures in synthesizing the heterocyclic core of that structure, success was finally realized through the development of a novel hetero-pinacol-based macrocyclization cascade sequence. Subsequent elaboration led to an advanced compound bearing both of the 12...

We have investigated dynamical heterogeneity in a highly supercooled liquid using molecular-dynamics simulations in three dimensions. Dynamical heterogeneity can be characterized by three quantities: correlation length ξ(4), intensity χ(4), and lifetime τ(hetero). We evaluated all three quantities consistently from a single order parameter. In a previous study [H. Mizuno and R. Yamamoto, Phys. ...

In the title compound, C(16)H(24)NO(+)·Br(-)·C(20)H(14)O(2), the N-hetero-cyclic six-membered ring assumes a half-chair conformation. The two naphthalene ring systems are nearly perpendicular to one another, making a dihedral angle of 89.5 (2)°. Inter-molecular O-H⋯Br hydrogen bonding helps to stabilize the crystal structure.

Three-dimensional hierarchical Prussian blue composed of ultrathin nanosheets was successfully synthesized by employing a self-aggregation and oriented attachment strategy. The unique structure highly increases the exposure of micropores and metal sites of Prussian blue to guests, thus significantly enhancing its hetero-catalysis and adsorption properties compared to cubic and commercial counte...

The hetero-interfaces between the perovskite (La1 xSrx)CoO3 (LSC113) and the Ruddlesden-Popper (La1 xSrx)2CoO4 (LSC214) phases have recently been reported to exhibit fast oxygen exchange kinetics. Vertically aligned nanocomposite (VAN) structures offer the potential for embedding a high density of such special interfaces in the cathode of a solid oxide fuel cell in a controllable and optimized ...

Since vancomycin-intermediate Staphylococcus aureus (VISA) was first reported in Japan in 1997, there has been great concern that heterogeneous vancomycin-intermediate S. aureus (hetero-VISA) is the putative precursor of VISA. To investigate the prevalence, clinical significance, and molecular epidemiology of S. aureus with reduced susceptibility to vancomycin, all consecutive isolates of S. au...
