Do Functional Tests Estimate Physical Activity in COPD?

The association between physical activity in daily life (PADL) and simple functional tests is not yet clearly understood in subjects with chronic obstructive pulmonary disease (COPD). Therefore, the aim of this study was to investigate the association of two functional tests (Sit-to-Stand test [STS] and the 4-Metre Gait Speed test [4MGS]) with PADL, as well as to identify whether these tests can discriminate those subjects who are physically inactive. In this cross-sectional study, 28 subjects with COPD performed the five repetitions Sit-to-Stand (STS5r), the 4MGS and used the DynaPort activity monitor for 7 days in order to assess PADL.

Lactation overnutrition-induced obesity impairs effects of exogenous corticosterone on energy homeostasis and hypothalamic-pituitary-adrenal axis in male rats.

Aims: Litter size reduction on the first days of life results in increased body weight and adiposity, with higher levels of circulating glucocorticoids. Obese rodents are more sensitive to the anabolic effects of glucocorticoids and less responsive to glucocorticoids feedback on hypothalamic-pituitary-adrenal (HPA) axis. This study aimed to evaluate effects of the treatment with corticosterone on metabolic responses and HPA axis in adult male rats reared in small litters.

Vasopressinergic Activity of the Suprachiasmatic Nucleus and mRNA Expression of Clock Genes in the Hypothalamus-Pituitary-Gonadal Axis in Female Aging.

The important involvement of the suprachiasmatic nucleus (SCN) and the activity of vasopressinergic neurons in maintaining the rhythmicity of the female reproductive system depends on the mRNA transcription-translation feedback loops. Therefore, circadian clock function, like most physiological processes, is involved in the events that determine reproductive aging. This study describes the change of mRNA expression of clock genes, , , and , in the hypothalamus-pituitary-gonadal axis (HPG) of female rats with regular cycle (RC) and irregular cycle (IC), and the vasopressinergic neurons activity in the SCN and kisspeptin neurons in the arcuate nucleus (ARC) of these animals.

Development of a Chemical Reproductive Aging Model in Female Rats.

Women are born with an abundant but finite pool of ovarian follicles, which naturally and progressively decreased during their reproductive years until menstrual periods stop permanently (menopause). Perimenopause represents the transition from reproductive to non-reproductive life. It is usually characterized by neuroendocrine, metabolic and behavioral changes, which result from a follicular depletion and reduced number of ovarian follicles.

Experimental Infection Induces Pain in Mice Dependent on Early Spinal Cord Glial Cells and NFκB Activation and Cytokine Production.

The neglected tropical infirmity Chagas disease (CD) presents high mortality. Its etiological agent is transmitted by infected hematophagous insects. Symptoms of the acute phase of the infection include fever, fatigue, body aches, and headache, making diagnosis difficult as they are present in other illnesses as well.

Sex differences in glucocorticoids-induced anabolic effects in rats.

Glucocorticoids (GC) increase food intake and body weight in humans and rodents and chronic stress and GC treatment-induced enhancement of the plasma concentration of GC lead to obesity and metabolic changes. In response to hypercaloric treatment, males were shown to be more susceptible to obesity than females, demonstrating that sex differences may affect energy homeostasis. The objective of the current study was to evaluate the effects of prolonged (28 days) treatment with dexamethasone or corticosterone on food intake and body weight gain in intact rats, both male and female.

Stability of early treatment of anterior open bite: clinical performance of bonded lingual spurs.

Anterior open bite (AOB) is a malocclusion that generates aesthetic, speech, feeding and psychological issues, a fact that emphasises the importance of conducting early treatments to fix the disorder. Finger-sucking, pacifiers and oral habits are the main aetiological factors of AOB; thus, it is necessary to apply interceptive treatments focused on correcting and improving bite stability during childhood in order prevent the need of undergoing advanced therapy. The aim of this article is to present the early diagnosis of aetiological factors causing severe AOB and the interceptive treatment based on the use of bonded lingual spurs for one year.
