Apoe isoforms in patients with psoriasis
Ferreira, J.C.P.; Torres, T.; Carvalho, C.A.; Bettencourt, A.; Leal, B.; Vasconcelos, C.; Costa, P.P.; Selores, M.; Silva, B.M.Introduction: Psoriasis is a chronic inflammatory skin disease affecting 2–3% of the world population. Patients with psoriasis (Ps) have higher prevalence of lipid disorders when compared to unaffected individuals. These patients, especially those with severe and prolonged disease, have an increased morbidity and mortality from cardiovascular events. Apolipoprotein E (ApoE), a protein involved in lipid metaboli...

Semiclassical approximation for the partition function in QFT
Bessa,A.; Carvalho,C.A.A. de; Fraga,E.S.; Gelis,F.In this paper we discuss the semiclassical approximation for the thermodynamics of scalar fields. We construct a semiclassical propagator in terms of two solutions of an ordinary differential equation. The main result is an analytic (non-perturbative) expression for the partition function written in terms of known quantities.
Supressão da resposta imunitária humoral causada pela citrinina
Carvalho,C.A.; Fernandes,B.C.T.M.; Freire,R.B.Avaliou-se o efeito imunotóxico causado por exposição a baixas doses de citrinina (2,5mg kg-1) em camundongos albinos expostos à micotoxina antes (n=15), durante (n=15) e após (n=15) a imunização com antígeno inerte, representado por eritrócitos de carneiro - sheep red blood cells (SRBC). Quinze camundongos foram usados como controle (não intoxicados). Sete dias após o tratamento, os animais foram sangrados e o...
Summary talk: quantum field theory
Carvalho,C. A. A. deWe present a summary of the contributions to Quantum Field Theory of the XXIII Brazilian National Meeting on Particles and Fields.
Pollen spectrum of honey of "uruçu" bee (Melipona scutellaris Latreille, 1811)
CARVALHO,C. A. L. de; MORETI,A. C. de C. C.; MARCHINI,L. C.; ALVES,R. M. de O.; OLIVEIRA,P. C. F. deIn spite of the importance of the "uruçu" bee as honey producer of excellent quality, as well, potential pollinator both in agricultural and natural ecosystems, mainly in North-eastern Brazil, just some information is found in literature about sources that such bees utilize to collect nectar and pollen. The identification of the plants visited by Melipona scutellaris was accomplished with base on the analysis o...
Tunneling Catastrophes of the Partition Function
Carvalho,C. A. A. de; Cavalcanti,R. M.We use path-integrals to derive a general expression for the semiclassical approximation to the partition function of a one-dimensional quantum-mechanical system. Our expression depends solely on ordinary integrals which involve the potential. For high temperatures, the semiclassical expression is dominated by single closed paths. As we lower the temperature, new closed paths may appear, including tunneling pat...
Effects of Ca2+ Channel Blockers on Ca2+ Translocation Across Synaptosomal Memb...
Carvalho, C. A. M.; Coutinho, O. P.; Carvalho, A. P.The binding of [3H]nimodipine to purified synaptic plasma membranes (SPM) isolated from sheep brain cortex was characterized, and the effects of nimodipine, nifedipine, and (+)-verapamil on the [3H]nimodipine binding were compared to the effects on 45Ca2+ translocation under conditions that separate 45Ca2+ fluxes through Ca2+ channels from 45Ca2+ uptake via Na+/Ca2+ exchange. [3H]Nimodipine labels a single clas...
Effect of Monovalent Cations on Na+/Ca2 Exchange and ATP-Dependent Ca2+Transpor...
Coutinho, O. P.; Carvalho, A. P.; Carvalho, C. A. M.Two Ca2+ transport systems were investigated in plasma membrane vesicles isolated from sheep brain cortex synaptosomes by hypotonic lysis and partial purification. Synaptic plasma membrane vesicles loaded with Na+ (Na+i) accumulate Ca2+ in exchange for Na+, provided that a Na+ gradient (in2192out) is present. Agents that dissipate the Na+ gradient (monensin) prevent the Na+/Ca2+ exchange completely. Ca2+ accumu...
