The cytoplasmic membrane protein TonB spans the periplasm of the Gram-negative bacterial cell envelope, contacts cognate outer membrane receptors, and facilitates siderophore transport. The outer membrane receptor FhuA from Escherichia coli mediates TonB-dependent import of ferrichrome. We report the 3.3 angstrom resolution crystal structure of the TonB(More)
Disintegrins are a family of small (4-14 kDa) proteins that bind to another class of proteins, integrins. Therefore, as integrin inhibitors, they can be exploited as anticancer and antiplatelet agents. Acostatin, an alphabeta heterodimeric disintegrin, has been isolated from the venom of Southern copperhead (Agkistrodon contortrix contortrix). The(More)
Several techniques are used for detection of dental car-ies including a fiber-optic light (FOL), the method of optical coherence tomography (OCT), the method of fiber optic transillumination and the infrared tomogra-phy. For an assessment of light-induced fluorescence of hard dental tissues and primary dental caries diagnosis, we propose to use the domestic(More)
Currently, dental caries is the main reason of patient visits to dentists. A great deal of scientific work is dedicated to the study of enamel caries. The reason for this is the necessity for more detailed study of the pathogenesis of dental caries and other pathological processes occurring in tooth enamel. The application of modern high-technological(More)
Currently, various research methods of enamel and dentine for precautionary diagnostics of initial caries forms are developed; however, the vast majority of these do not provide objective criteria of caries diagnostics or are very difficult to perform. Therefore, the search of diagnostics and enamel research methods, which will allow predicting caries(More)

The article contains an overview of the literature on Mallory-Weiss syndrome. It analyzes numerous etiological factors, provides new insights into the pathogenesis of the disease, gives a description of a previously unknown dependence of discontinuous-hemorrhagic syndrome on the topographic and structural features of the cardioesophageal area of the(More)
The discovery of ligands that bind specifically to a targeted protein benefits from the development of generic assays for high-throughput screening of a library of chemicals. Protein powder diffraction (PPD) has been proposed as a potential method for use as a structure-based assay for high-throughput screening applications. Building on this effort, powder(More)
Xylanases catalyse the cleavage of various forms of xylan. A new crystal form of xylanase II from the fungus Trichoderma longibrachiatum that diffracts to better than 1 A resolution was grown from 12% PEG 8K, 0.1 M Tris pH 8.5, 0.2 M CaCl(2) with the addition of 2% glycerol to overcome crystal twinning. The crystals grow in a body-centered orthorhombic(More)
