During a hot Mediterranean summer, an expedition brought parasitologists from Brazil, France, Greece, Italy, and Serbia to a wooded area near Xanthi, Thrace, northeastern Greece, near the Turkish border, on the track of the vector of the little-known nematode Onchocerca lupi. The scientific purposes of the expedition blended then with stories of humans, animals, and parasites in this rural area.
aspartic proteases are a relatively small group of enzymes which express in various nematodes including onchocerca volvulus. an estimation of the gene copy number corresponding to the ov7a clone, which contains a cdna insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of o. volvulus, was made by slot blot analysis in a closely related species o. gibsonig...
Abstract A new flavone derivative named pachypodostyflavone (1), along with 8 known compounds (2–9) and a mixture of β-sitosterol stigmasterol were isolated from the stem bark Duguetia staudtii (Annonaceae), based on bioassay-guided fractionation. Their structures determined using high-resolution mass spectrometry NMR spectroscopic data, as well by comparison literature values their analogs. Se...
New examples of ansa-titanocenes derived from 1,2-bis(2-indenyl)ethane have been prepared. The titanium-mediated reductive coupling of 2-(hydroxymethyl)indenes provided a convenient method for substrate dimerization. Alkyl substitution of the indene ring at C(3) improved the regioselectivity of the reductive coupling to provide the ethylene bis(2-indenyl)ansa-ligands in 29–62% yield.
Two major human diseases caused by filariid nematodes are onchocerciasis, or river blindness, and lymphatic filariasis, which can lead to elephantiasis. The drugs ivermectin, diethylcarbamazine (DEC), and albendazole are used in control programs for these diseases, but are mainly effective against the microfilarial stage and have minimal or no effect on adult worms. Adult Onchocerca volvulus an...
