-Aqueous acetone extracts of shoots of Eurasian watermilfoil (Myriophyllum spicatum) exhibit a strong inhibitory action against various coccoid and filamentous cyanobacteria and to a slightly less extent against chlorophytes and diatoms. Bioassay-directed fractionation led to the isolation of a hydrolysable polyphenol, tellimagrandin II, which turned out to be the main inhibitory substance. Myr...

Production of an interferon-like substance was demonstrated in primary chick embryo cells inoculated with human adenoviruses. In this rescept various examined types behaved similarly. Treatment of the virus with homologous immune serum, heat or trypsin resulted in the loss of its inducing capacity. The presence of mycoplasma had no influence on the induction of the interferonlike substance due ...

Disinhibition is present in various maladaptive behaviors, including substance use disorders. Most previous research has assumed that disinhibition is a psychological construct that is relatively stable within individuals. However, recent evidence suggests that the ability to inhibit behavior fluctuates in response to environmental and psychological triggers. In this review we discuss some of t...

Nontuberculous mycobacteria, like other opportunistic premise plumbing pathogens, produce resistant biofilms on various surfaces in the system including pipes, tanks, and fittings. Since standard methods of water disinfection are ineffective eradicating biofilms, research into new agents is necessary. Essential oils (EOs) have great potential as anti-biofilm agents. Therefore, purpose this was ...

in the last few years, a lot of preclinical studies showed the therapeutic potential of stem cells in spinal cord injury (sci). neural stem cells (nscs) can be differentiated into all cell types of spinal cord. nscs are cells that maintain the capacity to differentiate into brain-specific cell types, and may also replace or repair of injury in central nervous system. here in, we describe the ef...

Pathogens use diverse molecular machines to penetrate host cells and manipulate intracellular vesicular trafficking. Viruses employ glycoproteins, functionally and structurally similar to the SNARE proteins, to induce eukaryotic membrane fusion. Intracellular pathogens, on the other hand, need to block fusion of their infectious phagosomes with various endocytic compartments to escape from the ...

A bacteriocin-like inhibitory substance, salivaricin A, was purified from cultures of Streptococcus salivarius 20P3 and was shown by ion spray mass spectrometry to have a molecular mass of 2,315 +/- 1.1 Da. Amino acid composition analysis demonstrated the presence of lanthionine, indicating that salivaricin A may be a member of the lantibiotic class of antibiotic substances. The sequence of eig...

Picea koraiensis Nakai (PK) is an evergreen tree. It plays important role in landscaping and road greening. Insect galls of PK are formed by parasitism the adelgid Adelges laricis. Except for phenolics, other chemical constituents biological activity insect gall from still unknown. Thus, here, we performed phytochemical analyses extracts, aiming to turn waste into treasure serve human health. e...
