Teleconsultations at a Pediatrics Outpatient Service in COVID-19 Pandemic: First Results.

Describe our experiences using teleconsultation approach to care for pediatric subspecialty follow-up patients during pandemic period. Synchronous teleconsultation solution was developed and implemented as a multiplatform/multimodality service, capable or running on desktop browsers and smartphones, and capable to handle chat, audio, and video. Term of consent was applied.

Differential Activation of Mitogen-Activated Protein Kinases, ERK 1/2, p38(MAPK) and JNK p54/p46 During Postnatal Development of Rat Hippocampus.

Mitogen-activated protein kinases (MAPKs) are a group of serine-threonine kinases, including p38(MAPK), ERK 1/2 and JNK p54/p46, activated by phosphorylation in response to extracellular stimuli. The early postnatal period is characterized by significant changes in brain structure as well as intracellular signaling. In the hippocampus MAPKs have been involved in the modulation of development and neural plasticity.

Dose-dependent sickness behavior, abortion and inflammation induced by systemic LPS injection in pregnant mice.

Objective: Clinical and experimental evidences indicate that intrauterine inflammation during pregnancy is associated to brain damage. The objective of this study is to determine the effects of lipopolysaccharide in temperature, cytokine production and sickness behavior of pregnant dams.

Methods: A single i.

Effects of lifestyle modifications on cognitive impairments in a mouse model of hypercholesterolemia.

Epidemiological studies indicate that high midlife plasma cholesterol levels increases the risk of Alzheimer's disease. Moreover, middle-aged familial hypercholesterolemia (FH) subjects show a particularly high incidence of mild cognitive impairments (MCI). These evidence points to hypercholesterolemia as one of the modifiable risk factors focused on prevention/treatment of cognitive deterioration.

Evaluation of the quality of life of children with celiac disease and their parents: a case-control study.

Purpose: The purpose of the present study was to evaluate the quality of life (QoL) of children with CD and of their parents and to compare it with that of children without CD and of their parents.

Methods: A case-control study was conducted to evaluate the quality of life of children (5-12 years) with CD and one of their parents, compared to the QoL of children without CD (and their parents as their caregivers ). The QoL was assessed by applying the following questionnaires: AUQUEI (children) and WHOQOL-BREF (parents).

Cellular prion protein modulates age-related behavioral and neurochemical alterations in mice.

The cellular prion protein (PrP(C)) is a neuronal-anchored glycoprotein that has been associated with various functions in the CNS such as synaptic plasticity, cognitive processes and neuroprotection. Here we investigated age-related behavioral and neurochemical alterations in wild-type (Prnp(+/+)), PrP(C) knockout (Prnp(0/0)) and the PrP(C) overexpressing Tg-20 mice. Three- or 11 month-old animals were submitted to a battery of behavioral tasks including open field, activity cages, elevated plus-maze, social recognition and inhibitory avoidance tasks.

Differential gender-related susceptibility to learning and memory deficits in mice submitted to neonatal freezing microgyria model.

Sexual dimorphism during mammalian neural development seems to contribute to differential gender-related incidence in malformations of cortical development in both humans and rodents. Here we investigated the existence of differential gender-related susceptibility to learning and memory deficits and brain injury severity in mice submitted to a microgyria model. Newborn male and female C57BL/6 mice (P0) were submitted to a unilateral freezing lesion (FL) using a cooled steel probe, placed over the right midline anteroposterior plane.

Mild cognitive deficits associated to neocortical microgyria in mice with genetic deletion of cellular prion protein.

The cellular prion protein (PrP(C)) has been implicated with the modulation of neuronal apoptosis, adhesion, neurite outgrowth and maintenance which are processes involved in the neocortical development. Malformations of cortical development (MCD) are frequently associated with neurological conditions including mental retardation, autism, and epilepsy. Here we investigated the behavioral performance of female adult PrP(C)-null mice (Prnp(0/0)) and their wild-type controls (Prnp(+/+)) presenting unilateral polymicrogyria, a MCD experimentally induced by neonatal freeze-lesion in the right hemisphere.
