Comparison of muscle activity distribution in the biceps brachii using monopolar and bipolar multichannel surface electromyography. [PDF]

PLoS ONE
The detailed distribution of muscle activity within the biceps brachii (BB) muscle during isometric contraction as contraction intensity increases is not yet fully understood using multichannel surface electromyography (EMG).

The differences in the adrenergic receptors of proximal urethra between sexes

Tzu Chi Medical Journal, 2023
Objectives: The bladder and urethra work as a physiologically functional unit to facilitate continence in the storage and voiding phase. Sex differences have been found in the urethral contraction in response to α-adrenergic receptor activation.

Regional Differences in Biceps Femoris Long Head Stiffness during Isometric Knee Flexion

Journal of Functional Morphology and Kinesiology, 2021
This study sought to investigate whether the stiffness of the biceps femoris long head differs between proximal and distal regions during isometric knee flexion at different contraction intensities and muscle lengths. Twelve healthy individuals performed

Equivalence between the Existence of Best Proximity Points and Fixed Points for Some Classes of Proximal Contractions

Axioms, 2022
In the year 2014, Almeida et al. introduced a new class of mappings, namely, contractions of Geraghty type. Additionally, in the year 2021, Beg et al.

Correlation of intraluminal esophageal pressure with the dynamic extension of tracheoesophageal voice in total laryngectomees [PDF]

Acta Cirúrgica Brasileira, 2013
PURPOSE: To evaluate and correlate the amplitude of esophageal contractions triggered by swallowing water with dynamic extension and habitual, strong and weak sound intensity in total laryngectomees wearing a tracheoesophageal prosthesis. METHODS: Thirty

A 1D pulse wave propagation model of the hemodynamics of calf muscle pump function [PDF]

, 2015
The calf muscle pump is a mechanism which increases venous return and thereby compensates for the fluid shift towards the lower body during standing. During a muscle contraction, the embedded deep veins collapse and venous return increases.

Best Proximity Points for Generalized Geraghty Quasi-Contraction Type Mappings in Metric Spaces

European Journal of Mathematical Analysis, 2023
In this paper, we introduce a new concept of α-φ-Geraghty proximal quasi-contraction type mappings and establish best proximity point theorems for those mappings in proximal T-orbitally complete metric spaces.

ALTERED ESOPHAGEAL MOTILITY DURING PERCEPTION OF BOLUS TRANSIT IN HEALTHY VOLUNTEERS [PDF]

Arquivos de Gastroenterologia, 2019
BACKGROUND: The perception of bolus transit through the thoracic esophagus may be caused by altered esophageal anatomy and function. OBJECTIVE: To evaluate the hypothesis that, in healthy volunteers, swallows followed by perception of esophageal bolus

Best Proximity Point for ${\Gamma }_{\tau }\mathcal{F}$-Fuzzy Proximal Contraction

Axioms, 2023
In this writing, first, we disclose the first and second category of a ΓτF-fuzzy proximal contraction for a mapping O:U→V which is nonself and also declare a fuzzy q-property to confirm the existence of the best proximity point for nonself function O ...
