Pore-forming bacteriocins: structural–functional relationships
Archives of Microbiology, 2018Peptides and proteins are important bioorganic compounds in nature, among which a special place is occupied by antimicrobial substances. There are more than 2000 different antimicrobial peptides (AMPs) produced by a variety of living organisms. Bacteriocins produced by bacteria are the minor group, whose chemical structures are most complicated among ...

Imaging the Pore Structure of Geomaterials
Science, 1995Laser scanning confocal microscopy can be used to image the pore structure of geologic materials in three dimensions at a resolution of 200 nanometers. The technique involves impregnation of the void space with an epoxy doped with a fluorochrome whose fluorescent wavelength matches the excitation wavelength.

Pore structure evolution of low-rank coal in China
International Journal of Coal Geology, 2019In China, low-rank coalbed methane (CBM) resources are in the early stage of exploration. The evolution of pore structure for these coals around the first coalification jump is incomplete.

Dependence of texture on the pore structure is one of the most important fields of research. This is due to high sample-to-sample variations in application of mechanical tests. Tension, compression and flexure tests are the most common mechanical tests used in texture evaluation.

Nuclear Pore Complex Structure in Birds
Journal of Structural Biology, 1997The nuclear envelope consists of two parallel membranes enclosing an aqueous lumen. In places there are pores in both membranes at which the two membranes are joined. Within these pores reside the nuclear pore complexes. The current structural models of the nuclear pore complex have been derived from a number of studies using different electron ...

Pore-like structures in biological membranes
Journal of Cell Science, 1977ABSTRACT In freeze-fracture replicas, biological membranes appear as smooth surfaces interrupted by random globular protrusions, the intramembrane particles. Smooth areas correspond to the membrane phospholipidic domain, while intramembrane particles are the morphological counterpart of membrane proteins. In the present work, examination
