Profile of antimicrobial potential of fifteen Hypericum species from Portugal
Nogueira, T.; Medeiros, M. A.; Marcelo-Curto, M. J.; García-Pérez, B. E.; Luna-Herrera, J.; Costa, M. C.The aim of the present study was the search for the industrial exploitation potential of 15 Hypericum species crops from Portugal. Although Hypericum perforatum is well known worldwide, scarce studies have been published of Hypericum spp. identified in Portugal. Extracts from 15 Hypericum species were screened for its antimicrobial activities against 2 Gram− and 2 Gram+ bacteria, 4 non-tuberculous Mycobacteriu...

Chronic excitotoxic lesion of the dorsal raphe nucleus induces sodium appetite
Cavalcante-Lima,H.R.; Badauê-Passos Jr.,D.; de-Lucca Jr.,W.; Lima,H.R.C.; Costa-e-Sousa,R.H.; Olivares,E.L.; Cedraz-Mercez,P.L.; Reis,R.O.We determined if the dorsal raphe nucleus (DRN) exerts tonic control of basal and stimulated sodium and water intake. Male Wistar rats weighing 300-350 g were microinjected with phosphate buffer (PB-DRN, N = 11) or 1 µg/0.2 µl, in a single dose, ibotenic acid (IBO-DRN, N = 9 to 10) through a guide cannula into the DRN and were observed for 21 days in order to measure basal sodium appetite and water intake and i...
c-Fos expression induced by electroacupuncture at the Zusanli point in rats sub...
Medeiros,M.A.; Canteras,N.S.; Suchecki,D.; Mello,L.E.A.M.In laboratory animals, acupuncture needs to be performed on either anesthetized or, if unanesthetized, restrained subjects. Both procedures up-regulate c-Fos expression in several areas of the central nervous system, representing therefore a major pitfall for the assessment of c-Fos expression induced by electroacupuncture. Thus, in order to reduce the effect of acute restraint we used a protocol of repeated re...
A liver metalloendopeptidase which degrades the circulating hypotensive peptide...
Carvalho,K.M.; Nava,R.A.; França,M.S.F.; Medeiros,M.A.S.; Camarão,G.C.; Juliano,L.A new metalloendopeptidase was purified to apparent homogeneity from a homogenate of normal human liver using successive steps of chromatography on DEAE-cellulose, hydroxyapatite and Sephacryl S-200. The purified enzyme hydrolyzed the Pro7-Phe8 bond of bradykinin and the Ser25-Tyr26 bond of atrial natriuretic peptide. No cleavage was produced in other peptide hormones such as vasopressin, oxytocin or Met- and L...
