Sedimentological and geochemical data in bed sediments from a tropical river-estuary system impacted by a developing megacity, Ho Chi Minh City - Vietnam.

Sedimentological and geochemical data were obtained for bed sediments from a tropical estuary environment in Vietnam in October 2014, January 2016, and November 2016. The data include grain-size distribution, percentage of clay, silt and sand, percentage of organic matter, concentration of total particulate phosphorus (TPP), concentration of particulate inorganic phosphorus (PIP), concentration of particulate organic phosphorus (POP), percentage of total nitrogen (TN), percentage of total carbon (TC), trace metals concentrations (V, Cr, Co, Ni, Cu, Zn, As, Mo, Cd, Pb) and major elements (Al, Fe, Mn). Geochemical indexes (Enrichment factor EF and Geo-accumulation Index I-geo) and sediment quality guideline (mean Effect Range Median quotients) were calculated.

Ability of Bacillus subtilis for treatment of rhinosinusitis in a murine model

Probiotic preparations of Bacillus subtilis (B. subtilis) have been used by humans to treat and prevent the common forms of diarrhea caused by bacteria and virus, as well as other infections. To develop preparations of B. subtilis as an intranasal form, the authors studied the persistence and the antirhinopharyngitis of B. subtilis given nasally to mice. Substantial numbers of B. subtilis were still present in the nasopharynx 6 days after inoculation. The reduction in bacterial growth was similar to the positive controls. Also a reduced histopathological score was evident in corresponding with treating by ampicillin and prednisolone. Specifically, the authors obtained superior results in mice having administration of a dose of B. subtilis a day before inoculation of S. pneumoniae
