The protein content of dry biomass of the microalgae Porphyridium cruentum, Scenedesmus almeriensis, and Muriellopsis sp. and of the cyanobacteria Synechocystis aquatilis and Arthrospira platensis was measured by the Lowry method following disruption of the cells by milling with inert ceramic particles. The measurements were compared with the Kjeldahl(More)
We examined the effects of orexin A on the mRNA levels of neuropeptide Y, agouti-related peptide, melanin-concentrating hormone, prepro-orexin and orexin receptors in the rat hypothalamus. Adult male rats were treated centrally (i.c.v.) with a single dose of orexin A (3 nmol). After 2, 6 and 12 h, neuropeptide Y, agouti-related peptide,(More)
In urethane-anesthetized rats the intrathecal (i.t.) injection of 100 nmol anandamide produced a hypotensive effect (-19.3+/-1.6 mm Hg; n=6) that was mimicked by i.t. administration of 0.25 nmol calcitonin gene-related peptide (CGRP; -26.2+/-1.8 mm Hg, n=4). Both effects were antagonized either by the CGRP receptor antagonist CGRP(8-37) (5 nmol; i.t.) or by(More)
This study examined the effect of intrathecal (i.t.) injection of the endocannabinoid anandamide in urethane-anesthetized rats. The tip of the i.t. cannula was positioned at the T(12)-L(1) level of the spinal cord. Either anandamide or its metabolically stable analogue methanandamide (25 to 100 nmol) produced dose-dependent decreases in the blood pressure(More)
The intrathecal (i.t.) injection of 50 and 100 nmol anandamide to urethane anesthetized rats induced a dose-dependent decrease in the mean blood pressure (-10.6+/-1.6 mmHg and -15.0+/-1.7 mmHg, respectively; n=6) whereas a lower dose of this endocannabinoid (25 nmol) was devoid of effect. Similar responses were obtained both with the non-metabolizable(More)
In pentobarbital-anesthetized rats, intrathecal injection of noradrenaline (NA; 6, 18 and 60 nmol) induced a dose-dependent increase in the mean blood pressure. The pressor response to NA (18 nmol) was blocked by pretreatment with the selective antagonist for N-methyl-D-aspartic acid (NMDA) receptors, 2-amino-5-phosphonovaleric acid (30 nmol), but not by(More)
The aim of this study was to examine whether intrathecal (i.t.) injection of metabotropic glutamate (mGlu) receptor agonists at the thoracolumbar level of the spinal cord causes changes either in the blood pressure or in the heart rate of pentobarbital anesthetized rats. The broad spectrum mGlu receptor agonist (+/-)-1-aminocyclopentane-(More)
PURPOSE Neurosurgery appears to be a reasonable alternative in carefully selected patients with refractory status epilepticus (RSE) and super-refractory status epilepticus (SRSE). We discuss the optimal timing of the surgery and the use of previous stereoelectroencephalography (SEEG) invasive evaluation. METHODS We identified 3 patients (two pediatric and(More)
IBAMar is a regional database that puts together all the physical and biochemical data provided by multiparametric probes and water sample analysis taken during the cruises managed by the Balearic Oceanographic Center of the Instituto Español de Oceanografía (COB-IEO) during the last four decades. Initially, it integrated data from hydrographic profiles(More)
BACKGROUND Gangliogliomas (GGs) are rare brain tumors, and their malignant changes are still less frequent. In these cases, almost always the malignant component is the glial one. However, there are few cases in which the neuronal component exhibits malignant transformation. CASE DESCRIPTION We described a case of a 14-year-old male patient who started(More)
