Esse texto segue o serpentear da Cobra Grande, Mãe D’água, ser que habita e encanta as águas profundas das terras brasilis antes do colonizador aqui pisar. Nesse movimento, relata experiências vividas na Teko Haw Maraka’nà, aldeia em contexto urbano cidade Rio de Janeiro, com experimentações Corpo-Terra. Lançamos flechas re-encanto, plantando sementes no território dança práticas somáticas para...

The unfolding kinetics of cardiotoxin analogue VI from Taiwan cobra (Naja naja atra) have been studied at 473 K, pH 7.0 in the presence of 0.1 M NaCl using molecular dynamics simulations for 50 ns. Trajectory structures stored at every 25 ps (2000 structures) were probed at molecular (RMSD and radius of gyration) and residue (RMSF, surface area accessibility and secondary structures) level reso...

Earlier work by the author and coworkers (Adams & Whittaker, 1948; Adams, 1949; Whittaker, 1949; Mounter & Whittaker, 1950; Mounter, 1951) has shown that the so-called 'true' or 'specific' cholinesterases of erythrocytes, brain and cobra venom, previously believed to act only on acetylcholine and a few other esters, are in reality capable of hydrolysing a wide range of non-choline esters, 3:3-d...

We wish to thank Mr G. T. Iles of Belle Vue, Manchester, for supplying us with the sample of python fat used in this investigation, and for the information concerning the animal; also Prof. J. W. Cook, F.R.S., for drawing our attention to the work on bile salts; the University of Glasgow for a scholarship held by one of us (R.P.P.) and Imperial Chemical Industries Ltd., for a grant towards the ...

Fc-receptor-mediated clearance and nonspecific phagocytic clearance were assessed after the infusion of monomeric human IgG, heat-aggregated human IgG, and a monoclonal anti-mouse macrophage FcII receptor antibody (2.4G2) into normal mice. Each agent blocked Fc-receptor function in vivo, but 2.4G2 was much more potent per microgram than the other agents. Monomeric IgG in blocking doses did not ...

Interest in the alternate or C3 shunt complement pathway has recently been generated by a number of reports (1-5). Its presence in invertebrates points to a primitive phylogenetic appearance (6). The C3 shunt can be triggered by high molecular weight polysaccharides in a manner reminiscent of the properdin system (7). Once activated by cobra venom, erythrocytes and other cells can be lysed in t...
