Prevalence of participation of Brazilian aged people in Advanced Activities of Daily Living and associated factors.

Objective: To estimate the prevalence of participation of aged Brazilians in Advanced Activities of Daily Living and associated factors.

Methods: Cross-sectional study developed with secondary data from the National Health Survey. Aged people (60 years old or older) were included.

Oropharyngeal geometry and acoustic parameters of voice in healthy and Parkinson's disease subjects.

Purpose: to verify whether there are differences in acoustic measures and oropharyngeal geometry between healthy individuals and people with Parkinson's disease, according to age and sex, and to investigate whether there are correlations between oropharyngeal geometry measures in this population.

Methods: 40 individuals participated, 20 with a diagnosis of Parkinson's disease and 20 healthy individuals, matched by age, sex, and body mass index. Acoustic variables included fundamental frequency, jitter, shimmer, glottal-to-noise excitation ratio, noise, and mean intensity.

Relationship Between Oropharyngeal Geometry and Vocal Parameters in Subjects With Parkinson's Disease.

Objective: To verify whether the dimensions of different segments of the oropharyngeal cavity have different proportions between Parkinson's disease patients and vocally healthy subjects and investigate whether the measurements of these subjects' oropharyngeal geometry associate with their acoustic measurements of voice.

Method: Quantitative, descriptive, cross-sectional, and retrospective study with secondary data, approved by the Human Research Ethics Committee under no. 4.

Olfative and taste perception in Parkinson's disease.

Purpose: To analyze the olfactory and gustatory perception and discrimination and self-perception of smell and taste in people with Parkinson's disease, comparing them with healthy nodes.

Methods: Observational, analytical, cross-sectional, and quantitative study. Olfactory and gustatory perception and discrimination were verified following Parkinson's disease, compared to a control group, matched by sex and age, using the Olfactory Perception and Taste Strips Tests, respectively, after nasal cleaning and oral brushing.

A new lectin from the floral capitula of Egletes viscosa (EgviL): Biochemical and biophysical characterization and cytotoxicity to human cancer cells.

Egletes viscosa is a plant with therapeutic value due to its antibacterial, antinociceptive and gastroprotective properties. This study aimed to purify, characterize, and evaluate the cytotoxicity of a lectin (EgviL) from the floral capitula of E. viscosa.
