Water pollution from human activities is largely a result of the discharge wastewater and industrial waste into rivers. Phytoremediation, technique that uses plants to remove pollutants polluted waters, growing field research because its various environmental advantages. This study aims evaluate efficiency constructed wetland in removing treating waters Litani River Lebanon, by means two aquati...

In vitro assays of washed, excised roots revealed maximum potential ferric iron reduction rates of >100 micromol g (dry weight)(-1) day(-1) for three freshwater macrophytes and rates between 15 and 83 micromol (dry weight)(-1) day(-1) for two marine species. The rates varied with root morphology but not consistently (fine root activity exceeded smooth root activity in some but not all cases). S...

Increased focus is being placed on the ability of native vegetation to mitigate potential harmful effects of agricultural runoff, especially pyrethroid insecticides. Replicate 379 L Rubbermaid tubs (1.25 m [l] x 0.6 m [w] x 0.8 m [h]) were planted with individual species of cutgrass (Leersia oryzoides), cattails (Typha latifolia), bur-reed (Sparganium americanum), and powdery alligator-flag (Th...

Sparstolonin B (SsnB) is a novel bioactive compound isolated from Sparganium stoloniferum, an herb historically used in Traditional Chinese Medicine as an anti-tumor agent. Angiogenesis, the process of new capillary formation from existing blood vessels, is dysregulated in many pathological disorders, including diabetic retinopathy, tumor growth, and atherosclerosis. In functional assays, SsnB ...

Neuroblastoma is one of the most common solid tumors and accounts for ∼ 15% of all the cancer related deaths in the children. Despite the standard therapy for advanced disease including chemotherapy, surgery, and radiation, the mortality rate remains high for these patients. Hence, novel therapeutic agents are desperately needed. Here we examined the anticancer activity of a novel plant-derived...

Constructed wetland treatment of swine wastewater probably involves substantial denitrification. Our objective was to assess denitrification and denitrification enzyme activity (DEA) in such wetlands in relation to plant communities, N loading, carbon or nitrogen limitations, and water depth. Two wetland cells each 3.6 m wide and 33.5 m long were connected in series. One set of cells was plante...

Intra-cerebral hemorrhage (ICH) is a particularly severe type of stroke accounting for 10–15 % of all strokes and is associated with a mortality rate of 30–50%. Neuroinflammation contributes to ICH-induced secondary brain injury and understanding the mechanisms causing neuroinflammation can be helpful to find new treatments of ICH. Recent studies demonstrated that toll like receptor...
