Prosopis juliflora is used for feeding cattle and humans. Intoxication with the plant has been reported, and is characterized by neuromuscular alterations and gliosis. Total alkaloidal extract (TAE) was obtained using acid/basic-modified extraction and was fractionated. TAE and seven alkaloidal fractions, at concentrations ranging 0.03-30 microg/ml, were(More)
BACKGROUND Respiratory Bronchiolitis (RB), described by Niewoehner et al in 1974, is a common finding in heavy smokers and is characterised by the presence of pigmented macrophages within respiratory bronchioles and adjacent alveoli. In the 1980s, Myers et al described RB associated with interstitial lung disease (RBILD), which is a rare entity expressed as(More)
RATIONALE Clinical trial design in interstitial lung diseases (ILDs) has been hampered by lack of consensus on appropriate outcome measures for reliably assessing treatment response. In the setting of connective tissue diseases (CTDs), some measures of ILD disease activity and severity may be confounded by non-pulmonary comorbidities. METHODS The(More)
PURPOSE In this work, we analysed the potential of picoplanktonic marine cyanobacteria strains as a source of anticancer compounds by elucidating the cytotoxic mechanisms of an ethyl acetate fraction of Cyanobium sp. (LEGE06113) and the Synechocystis salina (LEGE06155) on the RKO colon adenocarcinoma cell line. METHODS Cytotoxicity was analysed by MTT.(More)
A new ergosterol analog, talarosterone (1) and a new bis-anthraquinone derivative (3) were isolated, together with ten known compounds including palmitic acid, ergosta-4,6,8(14),22-tetraen-3-one, ergosterol-5,8-endoperoxide, cyathisterone (2), emodin (4a), questinol (4b), citreorosein (4c), fallacinol (4d), rheoemodin (4e) and secalonic acid A (5), from the(More)
This paper examines the practice of abortion, especially induced abortion among low income women. The discussion is based on survey data collected between 1984 and 1985 in seven slum communities (favelas) situated in the metropolitan area of Rio de Janeiro, Brazil. Despite restrictive law, induced abortion is extremely frequent. Among married women 21.4 per(More)
Visceral involvement in systemic lupus erythematosus (SLE) extends beyond renal and cutaneous management. Pleuro-pulmonary lesions have been recognised and diffuse alveolar damage and hemorrhage are the most difficult patterns to control. Pulmonary compromise in clinical evolution of SLE differs from children to adults, both in morphological patterns and in(More)
Small-cell lung cancer (SCLC) is closely correlated with smoking and only sporadic cases have been reported in non-smoking patients. Environmental tobacco smoke and/or occupational risk factors have been suggested as possible causes of lung cancer in this subset of patients. However, particularly in relation to SCLC there is not enough reliable information.(More)
