Crystal dextrose is produced from solutions by enzymatic hydrolysis of starch. The process of crystallization of dextrose is the most complicated and responsible. The nucleation stage is particularly difficult. The common theory of crystallization connects the rate of nucleus formation with the surface tension of the solution. The purpose of the research is to activate the crystallization process by using surface-active substances (surfactants). Aliphatic alcohols: butanol, propanol, isobutanol, isopropanol were u...

Methods of parasite structures visualization using fluorescent probes are widely used in nowadays. The technological utilization of benzanthrone dyes is growing, but in biology studies they are still rarely used. Our studies show the advisability/expediency of using these dyes in investigation of helminthes structures. The aim of present study was to evaluate the novel synthesized luminophore AZP5 for efficient staining of trematodes for confocal laser scanning microscopy. All helminthes were previously preserved ...

Plants do not grow axenically in nature, but host a diverse community of microorganisms, termed as plant microbiota, colonizing different niches, both inside and outside their tissues, in the endosphere and ectosphere, respectively. These microorganisms are involved in major physiological processes, such as plant nutrition and plant resistance to biotic and abiotic stress factors. The aim of the research was to investigate the normal microbiota of rare plant species (listed with different degrees of danger in the ...

Alzheimer?s disease (AD) is associated with conformational changes of amyloid-? peptides, which result in peptide oligomerization and fibril formation and, finally, in the appearance of senile plaques and extensive neuronal loss. However, the factors regulating the process of plaque-associated beta-amyloid peptide (A?) aggregation are only partly understood. Therefore, several ?-amyloid peptide fragments have been synthesized by SPPS according to Boc/Bzl strategy. Binding of metal ions to ?-amyloid peptides was st...
