Hydrogen production by immobilized Synechocystis sp. PCC 6803
(2016)
The ability of the immobilized Synechocystis sp. PCC 6803 cells to produce hydrogen via an indirect light driven process was investigated. Cells were successfully immobilized in a calcium alginate gel matrix. Beads were ...
Identification of linear B-cell epitopes on myotoxin-II, a Lys49 phospholipase A2 homologue from Bothrops asper snake venom
(2012)
Knowledge on toxin immunogenicity at the molecular level can provide valuable information
for the improvement of antivenoms, as well as for understanding toxin structure–
function relationships. The aims of this study ...
Modulation of the Susceptibility of Human Erythrocytes to Snake Venom Myotoxic Phospholipases A2: Role of Negatively Charged Phospholipids as Potential Membrane Binding Sites
(2001-07-01)
Cerrophidion (Bothrops) godmani myotoxins I (CGMT-I) and II (CGMT-II), Asp-49 and Lys-49 phospholipases A(2) (PLA2s), which drastically differ in enzymatic activity, were devoid of direct hemolytic effects on erythrocytes ...
Isolation of Flavonoids from Deguelia duckeana and Their Effect on Cellular Viability, AMPK, eEF2, eIF2 and eIF4E
(2016)
Preparations of Deguelia duckeana, known in Brazil as timbó, are used by indigenous people to kill fish. Reinvestigation of its extracts resulted in the isolation and identification of 11 known flavonoids identified as ...

(2016)
El objetivo del presente trabajo fue evaluar la productividad de la microalga verde Chlorella sorokiniana UTEX 1230 con fertilizantes foliares usados en la agricultura y la comparación con el medio nutritivo Kolwitz (K3). ...
Criptosporidiosis: una zoonosis de reciente interés
(Adel. Microbiol. Enf. Infecc 3 p. 159-181, 1984)
Cryptosporidium, a coccidium described in 1907. causes subclinical infections and
diarrhea in many vertebrates including man. It departs from other Cryptosporidiiae in
its localization on the brush border of epithelial ...
An MTT-based method for the in vivo quantification of myotoxic activity of snake venoms and its neutralization by antibodies
(1993-05)
The reduction of the tetrazolium compound MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) was used as the basis for the development of a simple method for the quantitative estimation of metabolically ...
Biological and structural characterization of crotoxin and new isoform of crotoxin B PLA2 (F6a) from Crotalus durissus collilineatus snake venom
(2006)
A new crotoxin B isoform PLA2 (F6a), from Crotalus durissus collilineatus was purified from
by one step reverse phase HPLC chromatography using l-Bondapack C-18 column analytic.
The new crotoxin B isoform PLA2 (F6a), ...
Chromosomal defects in 34 male homosexuals, half of them with HIV antibodies
(Revista de Biologíaa Tropical 50(1):347-353, 2002, 2002-09)
Most of the research about viral interactions with human chromosomes was done during the sixties
and early seventies and very few was performed after the human immunodeficiency virus (HIV) appearance as
an epidemic in ...
