The Antibacterial Activity of Yeasts from Unique Biocenoses.

The replenishment of our stock of substances that possess a therapeutic potential is an important objective in modern biomedicine. Despite the important advances achieved in chemical synthesis, the natural diversity of organisms and microorganisms remains an important source of biologically active compounds. Here, we report the results of our study of a unique collection containing more than 3,000 samples of yeasts found on the Kamchatka Peninsula, the Kuril Islands, and Sakhalin Island, Russia.

[Pathogenetic aspects of diffuse lamellar keratitis after laser corneal refractive surgery].

This review analyzes the primary etiological factors of diffuse lamellar keratitis following various laser corneal refractive surgery techniques. The use of advanced diagnostic methods such as optical coherence tomography, confocal microscopy, and immunohistochemical methods has allowed for the identification of the main pathogenetic mechanisms underlying this condition, which will help improve the prevention, as well as assist with the development of optimal treatment strategies for this complication.

Exploring h-BN as a hydrogen conductor and depository.

The use of hexagonal boron nitride (h-BN) as a material for hydrogen storage is attributed to its ability to accommodate atomic and molecular hydrogen. However, the low diffusion barrier of molecular hydrogen within the h-BN structure does not fully explain the long-term stability of hydrogen bubbles observed in experimental work [L. He, H.

Electronic transitions and vibrational properties of bulk and monolayer g-CN, and a g-CN/MoS heterostructure from a DFT study.

Successful recognition of a dynamically stable carbonitride structure revealed that unlike other planar layered structures in the case of g-CN the stable configurations are distorted [J. Wang , , 2017, (7), 2694-2707, DOI: https://doi.org/10.
