When producing aquaculture products in conditions of increased planting densities aquatic organisms, it is not always possible to avoid various diseases and injuries. The use therapeutic baths feeds often does al-low achieve a positive effect. Therefore, the cyclodextrin nanosponge with prophylactic agents included their cavity will allow targeted effect on bioavailability substances formation ...
ß -carotene is a human nutrient found in plants or animals. It is also can be synthesized chemically. It is lipid-soluble, and is yellow, orange or red in color. ß-Carotene can be cleaved into vitamin A in vivo. The most abundant form of ß-carotene in human serum is trans isomer; cis isomers such as 9-cis ß-carotene, 13-cis ß-carotene, and 15-cis ß-carotene are only present in trace amounts. ß-...

Cyclodextrins are naturally oligosaccharides which had cyclic glucopyranoside units even if six to form α-cyclodextrin (α-CD), seven β-cyclodextrin (β-CD) or eight γ-cyclodextrin (γ-CD) and some other derivatives. It has a truncated cone shape with hydrophobic cavity hydrophilic from the external surface of cyclodextrins. Gold nanoparticles incorporated cyclodextrins enhanced optical electrical...
Although many endo-ß-1,4-glucanases have been isolated in invertebrates, their cellulolytic systems are not fully understood. In particular, gastropod feeding on seaweed is considered an excellent model system for production of bioethanol and renewable bioenergy from third-generation feedstocks (microalgae and seaweeds). In this study, enzymes involved in the conversion of cellulose and other p...
This paper examines an infinite family of proximity drawings of graphs called open and closed ß-drawings, first defined by Kirkpatrick and Radke [15, 21] in the context of computational morphology. Such proximity drawings include as special cases the well-known Gabriel, relative neighborhood and strip drawings. Complete characterizations of those trees that admit open /^-drawings for 0 < ß < iz...
Herein we report the efficient extraction of aromatic analytes from crude oil and tar balls using multiple cyclodextrin derivatives. The known propensity of the cyclodextrins to bind hydrophobic guests in their hydrophobic interiors enhanced the extraction of aromatic analytes from the oil layer to the aqueous layer, with methyl-β-cyclodextrin and β-cyclodextrin providing the most significant e...
Wound healing is a complex process that relies on proper levels of cytokines and growth factors to successfully repair the tissue. Of particular interest are the members of the transforming growth factor family. There are three TGF-ß isoforms-TGF- ß 1, 2, and 3, each isoform showing a unique expression pattern, suggesting that they each play a distinct function during development and repair. Pr...
in this paper, synthesized (raw) multi-walled carbon nanotube (rmwcnts) surfaces were modified with chitosan and β-cyclodextrin using chen’s soft cutting technique. raw and surface modified multi-walled carbon nanotubes were observed by transmission electron microscope (tem). the results showed that chitosan and β-cyclodextrin could attach to the outer surface of nanotubes, wrapping the nanotub...
