Static and Functional Balance in Individuals With COPD: Comparison With Healthy Controls and Differences According to Sex and Disease Severity.

Background: Studies have shown that individuals with COPD have impaired body balance, probably caused by the disease's multisystemic manifestations plus age-related decline in balance, potentially increasing the risk of falling and its consequences. However, little is known about the profile of individuals with COPD who present balance impairments, especially related to sex and disease severity stages. The aim of this work was to compare static and functional balance between subjects with COPD and healthy controls and to check possible differences according to sex and degrees of disease severity.

[Subjects and Methods] Ten patients underwent removal of lower third molars using the same surgical protocol and pharmacological approach. In the postoperative period, all patients received four consecutive daily sessions of low-level laser therapy, beginning 24 hours after the surgery.

Acute stress affects the global DNA methylation profile in rat brain: modulation by physical exercise.

The vulnerability of epigenetic marks of brain cells to environmental stimuli and its implication for health have been recently debated. Thus, we used the rat model of acute restraint stress (ARS) to evaluate the impact of stress on the global DNA methylation and on the expression of the Dnmt1 and Bdnf genes of hippocampus, cortex, hypothalamus and periaqueductal gray (PAG). Furthermore, we verified the potential of physical exercise to modulate epigenetic responses evoked by ARS.

Materials and Methods: The sample consisted of 52 patients divided into two groups: the control group (n  =  26; mean age  =  14.85 years), which consisted of patients not suffering from bronchial asthma; and the asthmatic group (n  =  26; mean age  =  16.

Factors related to oral health-related quality of life of independent brazilian elderly.

The aim of this cross-sectional study was to assess the factors associated with the impact of oral health on the quality of life in a sample of 504 Brazilian independent elderly.

The purpose of this study was to assess the current knowledge and recommendations of obstetricians and dentists as to the dental care to pregnant patients in the cities of Londrina/PR and Bauru/SP, Brazil. Questionnaires were distributed to professionals of both cities, arguing on the following issues: oral health during pregnancy; contact between prenatal care and dental care providers; prenatal fluoride supplementation; selection of therapeutic agents for local anesthesia, pain control and treatment of infection; and dental procedures that can be performed during each trimester. Data were analyzed by frequency of responses and statistical analyses were carried out using X(2) (type of workplace/service) and t test (time since graduation), significant if p<0.

The paraventricular nucleus of hypothalamus mediates the pressor response to noradrenergic stimulation of the medial prefrontal cortex in unanesthetized rats.

The medial prefrontal cortex (MPFC) is a structure that is also involved in cardiovascular modulation. The injection of norepinephrine (NE) into the prelimbic (PL) area of the MPFC of unanesthetized rats evokes a pressor response which is mediated by acute vasopressin release. Vasopressin is synthesized by magnocellular cells of the paraventricular (PVN) and supraoptic nucleus (SON) of the hypothalamus.
