ASSOCIATION BETWEEN POSTURAL BALANCE AND ANTHROPOMETRIC INDEXES IN ELEMENTARY SCHOOLCHILDREN.

Objective: To analyze the association between postural balance and anthropometric indicators in elementary school students.

Methods: This cross-sectional, descriptive and quantitative study included children enrolled in the first year of elementary school, of both sexes, in the age group of 6 to 7 years. Children with any physical or cognitive impairment, children who did not participate in all stages of the study evaluation, or those who failed to perform postural balance assessments were excluded.

Diphenyl diselenide diet intake improves spatial learning and memory deficits in hypothyroid female rats.

Cognitive deficits have been observed in different animal models of adult-onset hypothyroidism. Thus, this study was delineated to evaluate whether diphenyl diselenide, an organoselenium compound with neuroprotective and antioxidant properties, could afford protection against the detrimental effects of hypothyroidism on behavioral parameters. Hypothyroidism condition was induced in female rats by continuous exposure to methimazole (MTZ) at 20 mg/100 ml in the drinking water, during 3 months.

Effect of repeated restraint stress and clomipramine on Na+/K+-ATPase activity and behavior in rats.

Activation of the limbic-hypothalamic-pituitary-adrenal axis (LHPA) and the release of glucocorticoids are fundamental for the adaptive response and immediate survival of an organism in reaction to acute stimuli. However, high levels of glucocorticoids in the brain may produce neuronal injury and a decrease of Na(+)/K(+)-ATPase activity, with effects on neurotransmitter signaling, neural activity, as well as the whole animal behavior. Clomipramine is a tricyclic antidepressant that inhibits the reuptake of serotonin and norepinephrine by indirect actions on the dopaminergic system and LHPA axis.

Clomipramine treatment and repeated restraint stress alter parameters of oxidative stress in brain regions of male rats.

This study aimed to compare the effects of repeated restraint stress alone and the combination with clomipramine treatment on parameters of oxidative stress in cerebral cortex, striatum and hippocampus of male rats. Animals were divided into control and repeated restraint stress, and subdivided into treated or not with clomipramine. After 40 days of stress and 27 days of clomipramine treatment with 30 mg/kg, the repeated restraint stress alone reduced levels of Na(+), K(+)-ATPase in all tissues studied.
