Correlation between fertility and levels of protein, sugar and free amino acids in seminal plasma of Nelore bulls
Provedor de dados: 45
Autores: Assumpção,T.I.; Torres Júnior,R.A.A.; Sousa,M.V.; Ricart,C.A.O.
Correlations between fertility and the concentrations of proteins, reducing sugars and 17 types of free amino acids in the seminal plasma of Nelore bulls were estimated. The samples were collected from 19 bulls that had high quality semen, according to physical and morphological analyses. The bulls had their fertility scores estimated based on the pregnancy of the females mated to them during three consecutive breeding seasons, either by artificial insemination or by natural breeding. A large variability in the concentrations of the molecules was observed among the samples and a significant correlation coefficient (r= 0.90) between levels of proteins and reducing sugars was estimated. None of the components showed a significant correlation with fertility.

In this study, the behavioral and electroencephalographic (EEG) analysis of seizures induced by the intrahippocampal injection in rats of granulitoxin, a neurotoxic peptide from the sea anemone Bunodosoma granulifera, was determined. The first alterations occurred during microinjection of granulitoxin (8 µg) into the dorsal hippocampus and consisted of seizure activity that began in the hippocampus and spread rapidly to the occipital cortex. This activity lasted 20-30 s, and during this period the rats presented immobility. During the first 40-50 min after its administration, three to four other similar short EEG seizure periods occurred and the rats presented the following behavioral alterations: akinesia, facial automatisms, head tremor, salivation,...

Partial sequence and toxic effects of granulitoxin, a neurotoxic peptide from the sea anemone Bunodosoma granulifera
Provedor de dados: 56
Autores: Santana,A.N.C.; Leite,A.B.; França,M.S.F.; França,L.; Vale,O.C.; Cunha,R.B.; Ricart,C.A.O.; Sousa,M.V.; Carvalho,K.M.
A neurotoxic peptide, granulitoxin (GRX), was isolated from the sea anemone Bunodosoma granulifera. The N-terminal amino acid sequence of GRX is AKTGILDSDGPTVAGNSLSGT and its molecular mass is 4958 Da by electrospray mass spectrometry. This sequence presents a partial degree of homology with other toxins from sea anemones such as Bunodosoma caissarum, Anthopleura fuscoviridis and Anemonia sulcata. However, important differences were found: the first six amino acids of the sequence are different, Arg-14 was replaced by Ala and no cysteine residues were present in the partial sequence, while two cysteine residues were present in the first 21 amino acids of other toxins described above. Purified GRX injected ip (800 µg/kg) into mice produced severe neurotoxic...
