Diabetes mellitus (DM) is a complex disease, being one of the most prevalent diseases worldwide. As a consequence, pregnancy-associated diabetes is increasingly common. Given the numerous studies about the influence of diabetes on offspring of diabetic rat dams, the neurological outcome is of outmost importance. This paper aimed at evaluating the(More)
This study addresses the effects of induced hyperthermia on post-ischemic rat brain evaluated histologically and/or immunohistochemically after 7-day, 2-month or 6-month survival. Hyperthermia (38.5 degrees - 40 degrees C) maintained (by heating the cage environment to 34-35 degrees C) for two consecutive periods of 5 and 9 h timed, respectively, from 4-(More)
A large body of evidence has shown that prolonged paradoxical sleep deprivation (PSD) results in hypothalamic-pituitary-adrenal (HPA) axis activation, and in loss of body weight despite an apparent increase of food intake, reflecting increased energy expenditure. The flowerpot technique for PSD is an efficient paradigm for investigating the relationships(More)
This study evaluated the effects of bone marrow-derived mesenchymal stem cells (BMSCs) or their conditioned medium (CM) on the repair and prevention of Acute Kidney Injury (AKI) induced by gentamicin (G). Animals received daily injections of G up to 20 days. On the 10(th) day, injections of BMSCs, CM, CM+trypsin, CM+RNase or exosome-like microvesicles(More)
Systemic administration of cyclosporine A (CsA) in single daily doses provides a powerful protection to the ischemic rat brain only to sites where the blood-brain barrier (BBB) is disrupted. This study was aimed at evaluating the effectiveness of prolonged treatment and multiple daily doses of systemic CsA following transient global ischemia in rats without(More)
PURPOSE Animal models are useful for the study of status epilepticus (SE)-induced epileptogenesis and neurological sequelae, especially during early brain development. Here, we show several permanent abnormalities in animals subjected to multiple SE during early development. METHODS Wistar pup rats (7 to 9 days old) were subjected to three consecutive(More)
Autoimmunity has been associated with vitamin D deficiency and resistance, with gene polymorphisms related to vitamin D metabolism frequently described in affected patients. High doses of vitamin D3 may conceivably compensate for inherited resistance to its biological effects. This study aimed to assess the efficacy and safety of prolonged high-dose vitamin(More)
It is well known that the uncoupling between local cerebral glucose utilization (LCGU) and local cerebral blood flow (LCBF), i.e. decrease in LCBF rates with high LCGU, is frequently associated with seizure-induced neuronal damage. This study was performed to assess if the neuroprotective effect of the adenosinergic A(1) receptor agonist(More)
Choline - now recognized as an essential nutrient - is the most common polar group found in the outer leaflet of the plasma membrane bilayer. Brain ischemia-reperfusion causes lipid peroxidation triggering multiple cell death pathways involving necrosis and apoptosis. Membrane breakdown is, therefore, a major pathophysiologic event in brain ischemia. The(More)
We investigated the relationship between deficits in fear memory induced by sleep deprivation and pCREB expression in the basal and central nuclei of the amygdala. Sleep deprivation reduced pCREB expression in the central nucleus compared to control or sleep recovered groups, and in the basal nucleus only compared to sleep recovered group. Moreover, 24h of(More)
