In this review, we highlight the structure and molecular organization of synapses and discuss functional effects of synapse pathology in brain disease.”
“TB is still a global health problem. The selection and spread of multidrug-resistant and extensively drug-resistant Mycobocterium tuberculosis strains represents a threat for global TB control. The reappearance of TB has driven an increased interest in understanding the mechanisms of drug action and drug resistance, which could provide a significant contribution in the development of new antimicrobials. In this article, the Danusertib manufacturer authors describe the mode of action and the resistance mechanisms of

the principal first- and second-line antitubercular agents, namely isoniazid, ethionamide, ethambutol, D-Cycloserine, rifamycins, fluoroquinolones, streptomycin, linezolid LY2090314 and pyrazinamide. A brief outline of the seven drugs in clinical development is reported, showing how the development of new TB drugs is still required.”
“The micelles of a recently synthesized copolymer of poly(vinyl alcohol)-b-polyacrylonitrile added to the growth solution of the filamentous yeast Trichosporon cutaneum strain R57 led to the formation of a binary system consisting of micelles and cells. The resulting micelle/cell system was studied as a

model for the removal of toxic concentrations of heavy-metal ions (cadmium and copper) from aqueous solutions. The ionremoval efficiency mediated by this system was higher than for free-floating cells. The copper-removal efficiency from the solution reached a level of 65% after 24 h of cultivation, whereas the cadmium-removal efficiency reached 62% after 6 h of growth. For comparison, the free-floating cells removed 42% of copper and only 38% of cadmium from the solutions. The effects of surface interactions between the cells and polymer micelles on the biosorption capacity of the cells are discussed in the article. (C) 2010 Wiley Periodicals, Inc.

“Recent advances in the fields of microfabrication, biomaterials, and tissue engineering have provided new opportunities for developing biomimetic and functional tissues with potential applications in disease modeling, drug discovery, and replacing damaged tissues. An intact epithelium plays an indispensable role in the functionality of several organs such as the trachea, esophagus, and cornea. Furthermore, the integrity of the epithelial barrier and its degree of differentiation would define the level of success in tissue engineering of other organs such as the bladder and the skin. In this review, we focus on the challenges and requirements associated with engineering of epithelial layers in different tissues. Functional epithelial layers can be achieved by methods such as cell sheets, cell homing, and in situ epithelialization.
