Effects of 60Co gamma radiation on crotamine
(Associação Brasileira de Divulgação Científica (ABRADIC), 2001-12-01)
Ionizing radiation can change the molecular structure and affect the biological properties of biomolecules. This has been employed to attenuate animal toxins. Crotamine is a strongly basic polypeptide (pI 10.3) from Crotalus ...
Co-60 gamma irradiation prevents Bothrops jararacussu venom neurotoxicity and myotoxicity in isolated mouse neuromuscular junction
(Elsevier B.V., 2002-08-01)
The ability of gamma radiation from Co-60 (2000 Gy) to attenuate the toxic effects of Bothrops jararacussu venom was investigated on mouse neuromuscular preparations in vitro. A comparative study between the effects of ...
Poly [1,1'-bis(ethynyl)-4,4'-biphenyl(bis-tributylphosphine)Pt(II)] solutions used as low dose ionizing radiation dosimeter
(2013-06-17)
In this work, the effect of gamma radiation on the optical properties of polymetallayne poly[1,1'-bis(ethynyl)-4,4'-biphenyl(bis-tributylphosphine)Pt(II) ] (Pt-DEBP) in chloroform solution is studied. The samples were ...
Some effects of gamma-irradiated autologous sera on their donors
(1977-12-01)
The present paper is a further step to elucidate the effect of γ-irradiated molecules and their action as immunogens. Rabbits were bled, the total serum was γ-irradiated and reinjected to the autologous donor. Bleeding and ...
Influence of temperature upon effects of crotoxin and gamma-irradiated crotoxin at rat neuromuscular transmission
(Elsevier B.V., 2000-04-03)
The influence of temperature upon the effects of crotoxin (CTX)? from Crotalus durissus terrificus venom, and gamma-irradiated (Co-60, 2000 Gy) crotoxin (iCTX) was studied in rat neuromuscular transmission 'in vitro'. ...
QCD sum rule approach to the s->d gamma contribution to the Omega(-)->Xi(-)gamma radiative decay
(American Physical Soc, 2014)
EFFECT OF APIS-MELLIFERA BEE VENOM AND GAMMA-RADIATION ON BONE-MARROW CELLS OF WISTAR RATS TREATED INVIVO
(Soc Brasil Genetica, 1992-12-01)
To determine whether the venom of Apis mellifera can exert a radioprotective effect, by reducing the frequency of chromosome aberrations induced by radiation, five different experiments were performed on bone marrow cells ...
The study of natural radiation distribution in soil of São Bernardo do Campo.
(2008-10-05)
We have studied the distribution of natural radioactivity in the soil of five sites of the city São Bernardo do Campo, São Paulo, Brazil. The main contribution of the radiation dose is due to the isotope 40K, with smaller ...

Gamma Ray Irradiation of the Vasoactive Peptide Bradykinin Reveals a Residue- and Position-Dependent Structural Modification
(Springer, 2010-06-01)
In this work the effect of radical species generated by gamma ray irradiation of aqueous solution upon structure of vasoactive peptide bradykinin (BK, RPPGFSPFR) was investigated. Increasing doses of 1-15 kGy Co-60 gamma ...
