With the emergence of health related side effects synthetic substances, trend towards natural products has increased and directed researchers to determine their pharmacological properties. At same time, resistance microorganisms antibiotics used in treatment revealed that they should be controlled without allowing them gain resistance. In this study, total phenolic content, volatile composition...

Bez czarny (Sambucus nigra L.) jest szeroko rozpowszechniony; jego kwiaty i owoce to surowiec wykorzystywany w tradycyjnej medycynie oraz do suplementacji diety. Celem pracy było zbadanie 5 preparatów (o statusie suplementów diety specjalnego przeznaczenia żywieniowego) wspierających układ odpornościowy dzieci wieku od 1. roku życia starszych, zawierających sok lub ekstrakt z owoców bzu czarneg...

Herpetomonas megaseliae is a monoxenic trypanosomatid isolated from the phorid fly Megaselia scalaris. In the present report, the expression of cell surface sialoglycoconjugates in this parasite was analyzed by Western blotting, flow cytometry and fluorescence microscopy analyses using lectins that specifically recognize sialic acid residues. A strong reaction was detected when parasites were t...

Dr. Stephen Leeder didn’t take the job for the income or to improve his resumé. With a career spanning more than five decades, including a stint as dean of medicine at the University of Sydney, he was already one of the most well-known and respected academic physicians in Australia. It was, instead, an objective that guided his decision — two objectives, actually. Those objectives were expresse...

Tenotomy or tenectomy is at present the most usual procedure for diminishing the action of the superior oblique muscle (SO). Hughes and Bogart (1942) described the recession of the trochlea but this procedure has not been generally accepted. Foster (1946) performed a recession of the SO after temporary division of the superior rectus with a reasonably good result, but his technique was apparent...

We report here that (4R,9Z)-hexadec-9-en-4-olide [(R)-desmolactone] is a sex attractant or sex pheromone for multiple species and subspecies in the cerambycid genus Desmocerus. This compound was previously identified as a female-produced sex attractant pheromone of Desmocerus californicus californicus. Headspace volatiles from female Desmocerus aureipennis aureipennis contained (R)-desmolactone...

Ovarian carcinoma (OC) patients encounter the severe challenge of clinical management owing to lack of screening measures, chemoresistance and finally dearth of non-toxic therapeutics. Cancer cells deploy various defense strategies to sustain the tumor microenvironment, among which deregulated apoptosis remains a versatile promoter of cancer progression. Although recent research has focused on ...

A second lectin (SNA-II) has been isolated from elderberry (Sambucus nigra L.) bark by affinity chromatography on immobilized asialo-glycophorin. This lectin is a blood group nonspecific glycoprotein containing 7.8% carbohydrate and which is rich in asparagine/aspartic acid, glutamine/glutamic acid, glycine, valine, and leucine. Gel filtration on Superose 12 gave a single symmetrical peak corre...

Sambucus nigra (elder) are broadly used species to treat microbial infections. The potential antiviral activity and mechanism action of elder fruit (EF) in human epithelium cell (A549) cultures infected with H9N2 influenza virus were determined. The effect of various concentrations of EF on influenza virus replication was examined by using virus titration, quantitative real time RT-PCR, fusion ...

The invasive pest Drosophila suzukii is a fruit fly native to Asia that infests wide variety of fruits. Wild plant species are major reservoirs for D. populations but their infestation rates vary greatly among geographical areas. We aimed at disentangling the relative roles macroclimatic, landscape and local factors in rate elderberry fruits (Sambucus nigra), wild host Europe. collected across ...
