Analysis of Plantar Tactile Sensitivity in Older Women after Conventional Proprioceptive Training and Exergame.

Objective: To evaluate and compare the effects of conventional proprioceptive training and games with motion monitoring on plantar tactile sensitivity in older women.

Methods: A randomized controlled clinical trial, with 50 older women randomized into three groups: conventional proprioception (n = 17), games with motion monitoring (n = 16), and the control (n = 17). They underwent 24 intervention sessions, three times a week, for eight weeks.

Determination of nine prohibited -nitrosamines in cosmetic products by vortex-assisted dispersive liquid-liquid microextraction prior to gas chromatography-mass spectrometry.

An analytical method for the simultaneous determination of nine prohibited -nitrosamines in cosmetic products is presented. -nitrosamines are banned compounds in cosmetic products due to their harmful effects. Therefore, these compounds are not intentionally added to these products but, however, small amounts of them may be present due to unintentional causes, and thus sensitive methods for their analytical control are required.

Gestures and pauses to help thought: hands, voice, and silence in the tourist guide's speech.

In the body of research on the relationship between gesture and speech, some models propose they form an integrated system while others attribute gestures a compensatory role in communication. This study addresses the gesture-speech relationship by taking disfluency phenomena as a case study. Since it is part of a project aimed at designing virtual agents to be employed in museums, an analysis was performed on the communicative behavior of tourist guides.

Trace determination of prohibited acrylamide in cosmetic products by vortex-assisted reversed-phase dispersive liquid-liquid microextraction and liquid chromatography-tandem mass spectrometry.

An analytical method for the determination of residual acrylamide in cosmetic products containing potential acrylamide-releasing ingredients is presented. The method is based on vortex-assisted reversed-phase dispersive liquid-liquid microextraction (VA-RP-DLLME) to extract and preconcentrate acrylamide by using water as extraction solvent taking advantage the highly polar behavior of this analyte, followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) for its determination. Under optimized conditions (5 mL toluene as supporting solvent, 50 µL of water as extraction solvent, 1 min for vortex extraction time) the method was properly validated obtaining good analytical features (linearity up to 20 ng mL, method limits of detection and quantification of 0.

Factors influencing gait speed in community-dwelling older women: A Bayesian approach.

Background: Human gait is a complex task resulting from the interaction of sensory perception, muscle force output, and sensory-motor integration, which declines with the aging process and impacts gait speed in older women.

Research Question: What are the separate and combined impacts of sensory-motor factors on gait speed of older women?

Methods: Sixty healthy older women (69.3 ± 5.
