The LISP-I human colorectal adenocarcinoma cell line was isolated from a hepatic metastasis at the Ludwig Institute, São Paulo, SP, Brazil. The objective of the present study was to isolate morphologically different subpopulations within the LISP-I cell line, and characterize some of their behavioral aspects such as adhesion to and migration towards(More)
Motor evoked potentials (MEPs) to transcranial magnetic stimulation (TMS) increase in amplitude when obtained immediately after a period of exercise of the target muscle (postexercise facilitation). We studied postexercise facilitation of MEPs to TMS after periods of voluntary activation of either the ipsilateral or contralateral primary motor cortex(More)
This study addresses the relevance of colorectal-carcinoma-cell (CRC) CEA expression and degree of differentiation in natural-killer(NK)-mediated lysis susceptibility. A 51Cr-release cytotoxicity assay performed with 5 human CRC lines demonstrated that CRC CEA expression was related to resistance to NK lysis. Moreover, the addition of anti-CEA Fab fragments(More)
Monoclonal antibodies (MoAb) were produced against both salivary gland sporozoites (SGS) and oocyst sporozoites (OS) of Plasmodium gallinaceum, an avian malaria parasite. By indirect immunofluorescence, all of the MoAbs reacted with both SGS and OS of P. gallinaceum and two of the MoAbs cross-reacted weakly with P. berghei sporozoites. None of the MoAbs(More)
1. Monoclonal antibodies (MAbs) against surface antigens of Plasmodium gallinaceum sporozoites, an avian malaria parasite, were produced using spleen cells from mice immunized with sporozoites from mosquito salivary glands (SGS) or from midguts containing oocysts (OoS). 2. All of the 15 MAbs tested (11 anti-SGS and 4 anti-OoS) reacted with SGS and OoS by(More)
This paper reports the use of slow frequency transcranial magnetic stimulation of the right pre-frontal cortex in three patients with a diagnosis of major depressive episode according to the DSM-IV classification. There was a significant improvement in two patients, with a decrease of over 50% in the Hamilton Scale scores17 items. Possible indications and(More)

UNLABELLED 40 patients with the hepatosplenic form of schistosomiasis mansoni were selected for this study. Among 29 patients submitted to oral endoscopy there were 28 in whom oesophageal varices were demonstrated and 20 out of 21 patients who presented gastrointestinal haemorrhage had been operated on. All patients received a single oral dose of 40 mg/kg(More)
We and others have previously shown that some microorganisms, including bacteria, express on their surfaces receptors that specifically recognize extracellular matrix proteins, such as laminin, fibronectin, or both. The ability of microorganisms to adhere and to invade might depend on the existence of receptors which could, thus, be correlated with(More)
Sympathetic skin responses (SSRs) have been increasingly used as tests for autonomic function in the clinical setting. In spite of the known circadian rhythmicity of sympathetic function, however, normative studies have not addressed the possibility of circadian variability of SSR parameters. Ten normal volunteers (7 men, 3 women, aged 19 to 43) had SSR(More)
