1. The Induction of Hypothyroidism during Gestation Decreases Outer Hair Cell Motility in Rat Offspring
Abstract Introduction Perinatal hypothyroidism has a negative repercussion on the development and maturation of auditory system function. However, its long-term effect on auditory function remains unsettled. Objective To evaluate the effect of prenatal hypothyroidism on the auditory function of adult offspring in rats. Methods Pregnant Wistar rats were gi

2. Alice in Wonderland syndrome: “Who in the world am I?”
RESUMO Síndrome de Alice no País das Maravilhas (SAPM) é uma condição paroxística visual perceptiva e somestésica que pode ser encontrada em pacientes com enxaqueca, epilepsia, doença cerebrovascular ou infecções. A condição é relativamente rara e tem características alucinatórias peculiares. Objetivo: Discutir as potenciais vias envolvidas n

3. Calcium intake: good for the bones but bad for the heart? An analysis of clinical studies
ABSTRACT The proper dietary calcium intake and calcium supplementation, when indicated, are important factors in the acquisition of peak bone mass during youth and in the prevention of fractures in old age. In addition to its deposition in bone, calcium confers an increase in its resistance and exhibits important activities in different enzymatic pathways in

4. Involvement of the TRPV1 channel in the modulation of spontaneous locomotor activity, physical performance and physical exercise-induced physiological responses
Physical exercise triggers coordinated physiological responses to meet the augmented metabolic demand of contracting muscles. To provide adequate responses, the brain must receive sensory information about the physiological status of peripheral tissues and organs, such as changes in osmolality, temperature and pH. Most of the receptors involved in these affe

5. Mapping and signaling of neural pathways involved in the regulation of hydromineral homeostasis
Several forebrain and brainstem neurochemical circuitries interact with peripheral neural and humoral signals to collaboratively maintain both the volume and osmolality of extracellular fluids. Although much progress has been made over the past decades in the understanding of complex mechanisms underlying neuroendocrine control of hydromineral homeostasis, s

6. Estudo da atividade tipo-ansiolítica das folhas de Pimenta pseudocaryophyllus (Gomes) L.R. Landrum - Myrtaceae / Anxiolity - like activity of the leaves of Pimenta pseudocaryophyllus (Gomes) L.R. Landrum - Myrtaceae
Pimenta pseudocaryophyllus, popularly known as Craveiro, is the only species in this genus native to the cerrado of Brazil. Ethnopharmacological studies revealed medicinal use of P. pseudocaryophyllus extracts in treating menstrual and digestive problems as well as emotional tension in the form of soothing tea among other therapeutic applications in Brazilia

7. Effect of activation of canonical Wnt signaling by the Wnt-3a protein on the susceptibility of PC12 cells to oxidative and apoptotic insults
Wnt proteins are involved in tissue development and their signaling pathways play an important role during embryogenesis. Wnt signaling can promote cell survival, which is beneficial for neurons, but could also lead to tumor development in different tissues. The present study investigated the effects of a Wnt protein on the susceptibility of a neural tumor c

8. Processamento de sinais acústicos de diferentes complexidades em crianças com alteração de percepção da audição ou da linguagem / Acoustic signals processing of different complexities in children with auditory or language perception impairment
Introdução: Entender como estímulos acústicos complexos são codificados ao longo da via auditiva e como este processamento está relacionado em níveis mais inferiores e superiores da via, pode nos levar ao melhor entendimento de processos que subjazem a comunicação humana normal e alterada. Baseado na literatura que descreve anormalidades no processa

9. Relação entre as alterações estruturais do cerebelo e os transtornos psiquiátricos / Relationship between structural cerebellar changes and psychiatric disorders
Classically it was attributed to the cerebellum only functions regarding the control of movements, posture and balance. However, several studies have shown that the cerebellum also participates in the control of cognition, emotional processing and behavior through direct and indirect pathways. New evidence suggests that the cerebellum has structural and func

10. Involvement of catecholaminergic medullary pathways in cardiovascular responses to acute changes in circulating volume
Water deprivation and hypernatremia are major challenges for water and sodium homeostasis. Cellular integrity requires maintenance of water and sodium concentration within narrow limits. This regulation is obtained through engagement of multiple mechanisms and neural pathways that regulate the volume and composition of the extracellular fluid. The purpose of

11. Central chemoreceptors and neural mechanisms of cardiorespiratory control
The arterial partial pressure (P CO2) of carbon dioxide is virtually constant because of the close match between the metabolic production of this gas and its excretion via breathing. Blood gas homeostasis does not rely solely on changes in lung ventilation, but also to a considerable extent on circulatory adjustments that regulate the transport of CO2 from i

12. Visual contrast sensitivity in tonic-clonic epileptic patients
We measured the effects of epilepsy on visual contrast sensitivity to linear and vertical sine-wave gratings. Sixteen female adults, aged 21 to 50 years, comprised the sample in this study, including eight adults with generalized tonic-clonic seizure-type epilepsy and eight age-matched controls without epilepsy. Contrast threshold was measured using a tempor
