Boron nitride nanotubes (BNNTs) are of intense scientific interest due to their unique physiochemical properties and prospective applications in various nanotechnologies, particularly nanobiomedicine. A critical problem hamper‐ ing the application processing of BNNTs is the outer sidewall functionalization, which is primarily acquired to lead BNNTs dispersible in various solvents. Furthermore, ...

The relationships among the chemical, physical and biological aspects of compost and their role in suppression of turfgrass pathogens are reviewed. The composting process, mediated by microbial activity, is a€ected by physical and chemical characteristics which include temperature, aeration, moisture content, C:N ratio and pH. In the absence of parameter restrictions, the microbial community fo...

Drug-eluting stents have emerged as the most effective method for treating restenosis following percutaneous coronary interventions. This thesis investigates how drugs with similar physiochemical properties but different specific binding targets yield drastically different tissue transport, retention and ultimately efficacy independent of their putative biological effects. Our central hypothesi...

Exopolysacharides (EPS) are polymeric substances of microorganisms of high molecular weight and long chain composed of sugar residues secreted by them into the surrounding environment. Bacterial EPS are also complex mixture of macro molecular poly electrolytes including polysaccharides, proteins and nucleic acids, each comprising of variable molecular mass and structural properties. Three bacte...

In shallow lakes, different primary producers might impact the physiochemical characteristics of the sediment and the associated microbial communities. Until now, little was known about the features of sediment Archaea and their variation across different primary producer-dominated ecosystems. Lake Taihu provides a suitable study area with cyanobacteria- and macrophyte-dominated zones co-occurr...

The legume group is an important source of lipids and fatty acids in animal and human nutrition. As a food source, the neuropharmacological and other potential therapeutic benefits of broad beans (Vicia faba, VF), an ancient plant in cultivation, have been documented. The objective of this study was to evaluate the chemical composition, physiochemical properties and the thermal stability of the...

In the manufacture and use of the several thousand chemicals employed by technological societies, portions of these chemicals escape or are intentionally introduced into the environment. The behavior, fate, and to some extent the effects produced by these chemicals are a result of a complex interaction of the properties of the chemical with the various processes governing transport, degradation...

Carbon nanotubes (CNTs) are considered one of the most interesting materials in the 21st century due to their unique physiochemical characteristics and applicability to various industrial products and medical applications. However, in the last few years, questions have been raised regarding the potential toxicity of CNTs to humans and the environment; it is believed that the physiochemical char...

Frozen dairy products have characteristics of both yogurt and ice cream and could be the persuasive carriers of probiotics. Functions of the frozen yogurt containing viable bifidobacterial cells are recognized and favored by the people of all ages. We developed a kind of yogurt supplemented by Bifidobacterium species. Firstly, five strains of Bifidobacterium spp. (Bifidobacterium bifidum ATCC 1...

BACKGROUND Knowledge of the human leukocyte antigen (HLA) amino acid (AA) sequence combined with crystallographic structural data may enable prediction of the relative immunogenicity of individual donor/recipient HLA mismatches. METHODS Multiple sera from 32 highly sensitized patients awaiting kidney transplantation were screened using Luminex/single-antigen beads to determine the HLA-specifi...
