Purification, sequencing and structural characterization of the phospholipase A(1) from the venom of the social wasp Polybia paulista (Hymenoptera, Vespidae)
(Elsevier B.V., 2007-12-01)
The biochemical and functional characterization of wasp venom toxins is an important prerequisite for the development of new tools both for the therapy of the toxic reactions due to envenomation caused by multiple stinging ...
Effects of electroacupuncture on stress and anxiety-related responses in rats
(Acad Brasileira de Ciências, 2017)
The aim of this work was to investigate if eletroacupuncture at PC6 would modulate the stress-induced anxiety-like behavior and the level of activation of several brain areas. Rats were distributed in groups: control; ...
Circulating levels of sTNFR and discrepancy between cytotoxicity and immunoreactivity of TNF-alpha in patients with visceral leishmaniasis
(Blackwell Science Ltd, 2000-01-01)
Objective To study the influence of soluble tumour necrosis factor (TNF) receptors (sTNFR) on bioactivity; and immunoreactivity of TNF-alpha in patients with visceral leishmaniasis (Kala-azar) and to examine the association ...

(Amer Physiological Soc, 2010-05-01)
Pereira-Derderian DT, Vendramini RC, Menani JV, de Luca Jr. LA. Water deprivation-induced sodium appetite and differential expression of encephalic c-Fos immunoreactivity in the spontaneously hypertensive rat. Am J Physiol ...
EPILEPSY and HORMONAL-REGULATION - the PATTERNS of GNRH and GALANIN IMMUNOREACTIVITY in the HYPOTHALAMUS of EPILEPTIC FEMALE RATS
(Elsevier B.V., 1993-02-01)
Endocrine and reproductive alterations are frequently reported to occur in women with temporal lobe epilepsy as well as in female rats in different experimental models of limbic seizures. We have recently observed that ...
Profiling the Proteome of the Venom from the Social Wasp Polybia paulista: A Clue to Understand the Envenoming Mechanism
(Amer Chemical Soc, 2010-08-01)
The study reported here is a classical bottom-up proteomic approach where proteins from wasp venom were extracted and separated by 2-DE; the individual protein spots were proteolytically digested and subsequently identified ...
Liberação de óxido nítrico e tnf-α em macrófagos peritoneais na presença de Melampodium divaricatum (Asteraceae)
(2001-12-01)
The immune responses are mediated by a variety cells and molecules that cells secreted. Macrophages are the first cells that participate in the immune response, and, when are activated, release more than hundred compounds ...
Ativação de macrófagos por produtos naturais obtidos da Achillea millefolium L. (Asteraceae)
(2003-12-01)
Plants are a valuable source of natural products for the maintenance of human health. The purpose of this paper was the study of immunologic activity of yarrow (Achillea millefolium L.), a largely used plant in popular ...
A new Paracoccidioides brasiliensis 70-kDa heat shock protein reacts with sera from paracoccidioidomycosis patients
(Taylor & Francis Ltd, 2005-09-01)
A cDNA coding for a new member of the 70-kDa heat shock proteins (HSP70) family from the dimorphic and pathogenic fungus, Paracoccidioides brasiliensis, was cloned and characterized. the cDNA-deduced sequence coded for 655 ...
