The goals of the study were to compare data of vertical ground reaction force (GRF) parameters during level walking, stair ascent and descent on three different stair inclinations and three different age groups. Twenty healthy subjects of three age groups (young 33.7 years; middle 63.6 years; old 76.5 years) were tested during the seven test conditions with 8-10 repetitions. Vertical forces wer...

OBJECTIVE Patients with diabetes with peripheral neuropathy have a well-recognized increased risk of falls that may result in hospitalization. Therefore this study aimed to assess balance during the dynamic daily activities of walking on level ground and stair negotiation, where falls are most likely to occur. RESEARCH DESIGN AND METHODS Gait analysis during level walking and stair negotiatio...

Bitter compounds elicit an aversive response. In Drosophila, bitter-sensitive taste neurons coexpress many members of the Gr family of taste receptors. However, the molecular logic of bitter signaling is unknown. We used an in vivo expression approach to analyze the logic of bitter taste signaling. Ectopic or overexpression of bitter Grs increased endogenous responses or conferred novel respons...

BACKGROUND Stair-stepping motion is important in daily living, similar to gait. Knee prostheses need to have even more superior performance and stability in stair-stepping motion than in gait. The purpose of this analysis was to estimate in vivo knee motion in stair stepping and determine if this unique knee prosthesis function as designed. METHODS A total of 20 patients with Bi-Surface poste...

Although the visual system is known to provide relevant information to guide stair locomotion, there is less understanding of the specific contributions of foveal and peripheral visual field information. The present study investigated the specific role of foveal vision during stair locomotion and ground-stairs transitions by using a dual-task paradigm to influence the ability to rely on foveal ...

BACKGROUND Total hip replacement (THR) and total knee replacement (TKR) are common orthopaedic procedures. However, an optimal programme for post-operative rehabilitation has yet to be established. Stair negotiation is a challenging, habitual task, regularly used as a post-operative functional outcome measure; yet as a physical rehabilitation intervention it appears to be rarely used. AIM The...

OBJECTIVE The objective of the present study was to assess whether patients unable to perform a preoperative maximal stair climbing test had an increased incidence of morbidity and mortality after major lung resection compared to patients who were able to exercise. METHODS Three hundred and ninety one patients submitted to pulmonary lobectomy or pneumonectomy for lung cancer were analyzed. Fo...

Introduction There is no doubt that higher physical activity and fitness levels are inversely associated with the risk of cardiovascular disease (CVD) [1]. Yet, most Europeans and Americans do not meet current minimum physical activity recommendations [2] and the prevalence of CVD risk factors related to a sedentary lifestyle, such as obesity and diabetes, is increasing at an alarming rate [3,4...

A growing literature suggests taste stimuli commonly classified as "bitter" induce heterogeneous neural and perceptual responses. Here, the central processing of bitter stimuli was studied in mice with genetically controlled bitter taste profiles. Using these mice removed genetic heterogeneity as a factor influencing gustatory neural codes for bitter stimuli. Electrophysiological activity (spik...

BACKGROUND Bitter cumin (Centratherum anthelminticum (L.) Kuntze), is a medicinally important plant. Earlier, we have reported phenolic compounds, antioxidant, and anti-hyperglycemic, antimicrobial activity of bitter cumin. In this study we have further characterized the antioxidative activity of bitter cumin extracts in various in vitro models. METHODS Bitter cumin seeds were extracted with ...
