On October 26, 2001, the Report of the Committee of Inquiry on the Case Involving Dr. Nancy Olivieri, the Hospital for Sick Children, the University of Toronto and...

The aim of the study was to evaluate the antimicrobial activity of essential oils in vitro for possible application to reduce the content of microorganisms in the air of animal houses. The essential oils of Cymbopogon citrarus L. and Malaleuca alternifolia L. were screened against bacteria Staphylococcus aureus, Enterococcus faecium, Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis a...

A 67-year old man, receiving subcutaneous unfractionated heparin for 18 days was admitted because of femoral artery thrombosis. Biochemical analysis showed thrombocytopenia (29×109/L) and a positive test for heparin-dependent antiplatelet antibodies. Heparin-induced thrombocytopenia (HIT) was diagnosed. Computed tomography (CT) showed extensive thrombosis (Figure 1). Doppler ultrasonography dem...

Leaf extracts of Cymbopogon citratus (lemon grass) and bulb extracts of Allium sativum (garlic) extracted with various solvents (ethanol, ethyl acetate and aqueous for Cymbopogon citratus, and ethyl acetate chloroform and aqueous for Allium sativum) were evaluated for antidermatophytic activity against Microsporum spp. isolated from different water samples. Out of a total of 60 water samples an...

Carbon dioxide compensation values of mature leaves from 10 selections of citronella (Cymbopogon nardus [L.] Rendle) grown at 32/27 or 27/21 C day/night temperatures and three strains of lemongrass (Cymbopogon citratus [D.C.] Stapf. and Cymbopogon flexuosus [D.C.] Stapf.) grown at 8- or 15-hour photoperiods were measured in a controlled environment at 25 C. All leaves had low compensation value...

The aim of this study is to provide a better understanding of the genetic relationships within the widespread and highly polymorphic group of African giant shrews (Crocidura olivieri group). We sequenced 769 base pairs (bp) of the mitochondrial cytochrome b gene and 472 bp of the mitochondrial control region over the entire geographic range from South Africa to Morocco. The analyses reveal four...

Phytochemical analysis of Cymbopogon citratus revealed presence of bioactive compounds such as alkaloids, flavonoids, saponins, tannins, phenols, terpenoids etc. Each of the bioactive compounds were estimated and isolated separately by solventsolvent extraction for methanolic and aqueous extracts of Cymbopogon citratus. Saponins content was higher in methanolic extracts of Cymbopogon citratus (...
