Antioxidant and Antiulcerogenic Activity of the Dry Extract of Pods of Mart. ex Tul. (Fabaceae).

Ethnomedicinal studies in the Amazon community and in the Northeast region of Brazil highlight the use of fruits for the treatment of gastric problems. However, there are no data in the literature of this pharmacological activity. Thus, the aim of this paper is to provide a scientific basis for the use of the dry extract of pods (DELfp) for the treatment of peptic ulcers.

Implications of water hardness in ecotoxicological assessments for water quality regulatory purposes: a case study with the aquatic snail Biomphalaria glabrata (Say, 1818).

Water hardness is a property depending on the presence of alkaline earth metals, mainly calcium and magnesium. Among the strategies for water quality monitoring, ecotoxicological assays are performed to minimize impacts and classify water bodies. For these laboratory evaluations parameters are previously defined in the guidelines, including water hardness for both cultivation and testing medium.

Co-infection of disseminated histoplasmosis and tuberculosis in an AIDS patient.

Histoplasmosis is a fungal disease caused by the dimorphic fungus , recognized as an AIDS-defining illness since the Center for Disease Control's revision criteria in 1985. This infection is reported to be present in 5-20% of AIDS patients, and in 95% of the cases it is manifested in its disseminated form. Serum antibodies and/or antigen research can make diagnosis, but the demonstration of the agent by culture or histopathological examination remains the gold standard methods.
