SAFE-PORT project: an Approach to Port Surveillance and Protection
Martins, M.; Casimiro, R. P.; Gonçalves, S.; Rodrigues, A.; Captivo, M. E.; Gonçalves, G.; Sousa, J.; Calado, J.; Manso, M.; Lopes, J.; Freitas, J. C.SAFE-PORT is a recently started project addressing the complex issue of determining the best configurations of resources for harbour and port surveillance and protection. More specifically, the main goal is to find, for any given scenario, an adequate set of configuration solutions - i.e., number and type of sensors and equipments, their locations and operating modes, the corresponding personnel and other suppo...

Situação epidemiológica da brucelose bovina no Estado do Paraná
Dias,J.A.; Müller,E.E.; Dias,R.A.; Freitas,J.C.; Amaku,M.; Ferreira,F.; Silva,M.C.P.; Lôbo,J.R.; Figueiredo,V.C.F.; Gonçalves,V.S.P.; Ferreira Neto,J.S.Realizou-se um estudo para caracterizar a situação epidemiológica da brucelose bovina no Estado do Paraná. O Estado foi estratificado em sete circuitos produtores ou regiões. Em cada circuito foram amostradas aleatoriamente cerca de 300 propriedades e, dentro dessas, foi escolhido de forma aleatória um número pré-estabelecido de animais, dos quais foi obtida uma amostra de sangue. No total, foram amostrados 14....

Quantum information processing through nuclear magnetic resonance
Bulnes,J. D.; Bonk,F. A.; Sarthour,R. S.; Azevedo,E. R. de; Freitas,J. C. C.; Bonagamba,T. J.; Oliveira,I. S.We discuss the applications of Nuclear Magnetic Resonance (NMR) to quantum information processing, focusing on the use of quadrupole nuclei for quantum computing. Various examples of experimental implementation of logic gates are given and compared to calculated NMR spectra and their respective density matrices. The technique of Quantum State Tomography for quadrupole nuclei is briefly described, and examples o...
Dairy cow abortion associated with Neospora caninum and other infectious agents
Santos,A.P.M.E.; Navarro,I.T.; Bracarense,A.P.F.R.L.; Freire,R.L.; Marana,E.R.M.; Ogawa,L.; Alfieri,A.A.; Freitas,J.C.; Vidotto,O.Trinta e cinco vacas de rebanhos leiteiros da região Norte do estado do Paraná, com histórico de abortamento, foram pesquisadas sorologicamente para verificar a presença de anticorpos contra Neospora caninum, Toxoplasma gondii, Leptospira spp., Brucella abortus, BHV-1 e BVDV. Vinte e uma vacas apresentaram títulos sorológicos compatíveis com infecção. Todas elas, soropositivas para N. caninum, foram também soro...
Anti-inflammatory and antispasmodic activity of Ipomoea imperati (Vahl) Griseb ...
Paula,A.C.B.; Hayashi,L.S.S.; Freitas,J.C.Ipomoea imperati (Convolvulaceae) lives on the sandy shores of the Brazilian coast and in other areas of the world. The anti-inflammatory activity of a methanol-water extract of the leaves of I. imperati was investigated in experimental models of acute and subchronic inflammation. Topical application of the extract (10 mg/ear) inhibited mouse ear edema induced by croton oil (89.0 ± 1.3% by the lipid fraction wi...
Evaluation of the cholinomimetic actions of trimethylsulfonium, a compound pres...
Kerchove,C.M.; Markus,R.P.; Freitas,J.C.; Costa-Lotufo,L.V.Trimethylsulfonium, a compound present in the midgut gland of the sea hare Aplysia brasiliana, negatively modulates vagal response, indicating a probable ability to inhibit cholinergic responses. In the present study, the pharmacological profile of trimethylsulfonium was characterized on muscarinic and nicotinic acetylcholine receptors. In rat jejunum the contractile response induced by trimethylsulfonium (pD2 ...
Identification of hemolytic and neuroactive fractions in the venom of the sea a...
Lagos,P.; Duran,R.; Cerveñansky,C.; Freitas,J.C.; Silveira,R.Sea anemones are a rich source of biologically active substances. In crayfish muscle fibers, Bunodosoma cangicum whole venom selectively blocks the I K(Ca) currents. In the present study, we report for the first time powerful hemolytic and neuroactive effects present in two different fractions obtained by gel-filtration chromatography from whole venom of B. cangicum. A cytolytic fraction (Bcg-2) with components...
OCCURRENCE OF TETRODOTOXIN AND PARALYTIC SHELLFISH TOXINS IN Phallusia nigra (T...
FREITAS,J. C.; OGATA,T.; VEIT,C.H.; KODAMA,M.We have already shown the presence of guanidine neurotoxins in calcareous red algae and mussels collected in the São Sebastião channel (State of São Paulo, Brazil). It is known that these neurotoxins comprise more than 25 analogues such as tetrodotoxin (TTX) and derivatives plus the paralytic shellfish toxins (PST) found in a variety of marine, freshwater and amphibious species. Filter feeding animals generally...
