With the transport of plants around the globe, exotic species can readily spread disease to their native relatives; however, they can also provide genetic resistance to those relatives through hybrid breeding programmes. American chestnut (Castanea dentata) was an abundant tree species in North America until its decimation by introduced chestnut blight. To restore chestnut in North America, eff...

Forty eight samples (30 wastewater and 18 river water) were collected between July and November, 2010, from different sources in Cape Town, South Africa in order to characterize verotoxic non O157: H7 Escherichia coli strains. Samples (1 ml) were inoculated into MacConkey broth (MB, 9 ml) and incubated at 37°C for 24 h, after which a loopful of the MB was then spread onto Eosin Methylene Blue (...

Two new species of the leuctrid genus Rhopalopsole from China are described, R. curvispina Qian & Du, sp. nov. and R. triseriata Qian & Du, sp. nov. The new species are compared to similar species in R. dentata group and R. magnicercia group.

Early hyperthyroidism induces an aberrant growth of hippocampal mossy fibers both in the fascia dentata (supragranular layer) and in Ammon's horn (infrapyramidal layer of CA3). Using a quantitative autoradiographic method, we found a corresponding increase in kainic acid binding sites supporting previous observations of a very close association between mossy fiber terminals and kainic acid bind...

Curtisia dentata is used in African traditional medicine to treat variety of infections. C. dentata leaves were collected from Buffelskloof Nature Reserve, South Africa. The ethanol, chloroform, ethyl acetate and acetone extracts were evaluated for antimicrobial activity using micro dilution assay against Escherichia coli, Pseudomonas aeruginosa, Mycobacterium smegmatis, Mycoplasma hominis, Can...

Three new pterosins, named as semipterosin A (1), B (2) and C (3), together with 11 known pterosins (4–14), were isolated from the aerial parts of Pteris semipinnata. Their structures elucidated by HRESI-MS, NMR spectral data, CD literature comparisons. assessed for their anti-inflammatory activity. Compounds 1–3 inhibited NF-kB induction 40.7%, 61.9% 34.0%, respectively. This is first report i...
