| first isolation of cryptococcus gattii molecular type vgii and cryptococcus neoformans molecular type vni from environmental sources in the city of belém, pará, brazil. | cryptococcus neoformans and cryptococcus gattii are important agents of meningoencephalitis in humans in the city of belém. this clinical data suggests that the region may be a highly endemic area for the pathogenic cryptococcus species within the state of pará (pa), northern brazil. preliminary analysis of 11 environmental samples from the city of belém showed two positive locations, including a hollow of a kassod tree (senna siamea) colonized simultaneously by c. gattii molecular type vgii and ... | 2009 | 19722095 |
| the effects of arbuscular mycorrhizal fungal inoculation and mulch of contrasting chemical composition on the yield of cassava under humid tropical conditions. | the influence of arbuscular mycorrhizal fungus (amf), glomus deserticola, and leaf mulch from gliricidia sepium and senna siamea on the yield of cassava (manihot esculenta) in a degraded alfisol of southwestern nigeria was investigated. inoculation in conjunction with mulching increased cassava tuber yield by 40-278% over the control. the highest yield was obtained with g. sepium and s. siamea mulch applied together in equal proportions. the results are explained in the light of the growth-enhan ... | 2010 | 20364236 |
| anti-ulcer activity of leguminosae plants. | ulcer is the most common gastrointestinal disturbance resulting from an inadequate gastric mucosal defense. several drugs are available in the market to address the disease; however, these drugs are associated with unnecessary side effects. | 2014 | 24760067 |
| ethnobotanical study of medicinal plants used for the treatment of malaria in the plateau region, togo. | in togo, malaria constitutes a major public health problem but, until now, the population still mostly relies on herbal medicine for healing. this study aimed to document medicinal plants used for malaria therapy in the plateau region of the country. | 2016 | 27114686 |
| antiplasmodial activity of selected medicinal plants used to treat malaria in ghana. | the use of medicinal plants for the treatment of diseases including malaria is commonplace in ghanaian traditional medicine, though the therapeutic claims for most plants remain unvalidated. antiplasmodial activity of the aqueous extracts and successively obtained petroleum ether, ethyl acetate and methanol fractions of the whole phyllanthus fraternus plant, the leaves of tectona grandis, terminalia ivorensis and bambusa vulgaris, and roots of senna siamea were studied against plasmodium falcipa ... | 2016 | 27174028 |
| barakol-induced apoptosis in p19 cells through generation of reactive oxygen species and activation of caspase-9. | ethnopharmacological relevance: barakol, an anxiolytic agent isolated from senna siamea leaves which has been traditionally used for producing natural sleep, has been described as toxic to patients. aim of the study: the aim of current study was to investigate the molecular mechanism of barakol-induced toxicity in mouse embryonal carcinoma p19 cell model. materials and methods: xtt assay was used to determine cell viability in p19 cells treated with barakol. apoptotic cells were detected by hoec ... | 2011 | 21777666 |
| quantitative analysis of barakol content in senna siamea leaves and flowers by tlc-densitometry. | to develop a tlc-densitometric method for the determination of barakol content in senna siamea leaf and flower extracts, and to compare the barakol content in mature leaves, young leaves and young flowers of the plant which are consumed as a vegetable in curry. | 2007 | 17159364 |
| interspecific variation in vessel size, growth and drought tolerance of broad-leaved trees in semi-arid regions of kenya. | in semi-arid regions, trees often wither during the dry season. withering is sometimes manifest as die-back, whereby whithering results in shoot death, which progresses downward from the uppermost part of the crown. in this study, we measured the relationships between height growth and diameter at breast height, die-back frequency and severity, vessel size and specific hydraulic conductivity of four evergreen (senna siamea (lamk) h.s. irwin & barneby, jacaranda mimosifolia d. don, azadirachta in ... | 2006 | 16585035 |
| patterns of sugar feeding and host plant preferences in adult males of an. gambiae (diptera: culicidae). | sugar feeding by male mosquitoes is critical for their success in mating competition. however, the facets of sugar source finding under natural conditions remain unknown. here, evidence obtained in western burkina faso indicated that the distribution of an. gambiae s.s. (m and s molecular forms) males across different peri-domestic habitats is dependent on the availability of potential sugar sources from which they obtain more favorable sites for feeding or resting. among field-collected anophel ... | 2010 | 21175931 |
