The Bimanual Observation of The Hands (BOTH): Development, reliability, and validity for stroke rehabilitation

Plos.org 
En

by Debbie Rand, Nitsan Omer, Amihai Levkoviz, Samar Assadi Khalil

Importance

To efficiently perform bimanual daily tasks, bimanual coordination is needed. Bimanual coordination is the interaction between an individual’s hands, which may be impaired post-stroke, however clinical and functional assessments are lacking and research is limited.

Objectives

To develop a valid and reliable observation tool to assess bimanual coordination of individuals post-stroke.

Design

A cross-sectional study. Читать дальше...

Effects of pre-oxidation temperature and air volume on oxidation thermogravimetric and functional group change of lignite

To investigate the impact of the oxidation temperature and variations in airflow conditions on coal spontaneous combustion characteristics, pre-oxidized coal samples were prepared using a programmed temperature rise method. Synchronous thermal analysis experiments and Fourier transform infrared spectroscopy were conducted to explore changes in the thermal effects and functional group content of the coal samples, respectively. The results indicate... Читать дальше...

Effects of the pan-caspase inhibitor Q-VD-OPh on human neutrophil lifespan and function

Human neutrophils are abundant, short-lived leukocytes that turn over at a rate of approximately 1011 cells/day via a constitutive apoptosis program. Certain growth factors, inflammatory mediators and infectious agents can delay apoptosis or induce neutrophils to die by other mechanisms. Nonetheless, a large body of data demonstrates that apoptosis of untreated neutrophils typically ensues within 24 hours of cell isolation and in vitro culture. Читать дальше...

Association of varicose veins with the risk of heart failure: A nationwide cohort study

Plos.org 
En

by Dongyeop Kim, Moo-Seok Park, Ju-young Park, Tae-Jin Song

Background

Research investigating the association between varicose veins (VV) and heart failure has been limited. Here, we examine this association within a nationwide longitudinal cohort, hypothesizing an increased risk of heart failure associated with the presence of VV.

Methods

Our study included 390,436 participants based on health screening results conducted from 2005 to 2010 in the South Korean health screening cohort database. Читать дальше...

Research on boundary control of vehicle-mounted flexible manipulator based on partial differential equations

Plos.org 
En

by Yuzhi Tang

Vehicle-mounted flexible robotic arms (VFRAs) are crucial in enhancing operational capabilities in sectors where human intervention is limited due to accessibility or safety concerns, such as hazardous environments or precision surgery. This paper introduces the latest generation of VFRAs that utilize advanced soft materials and are designed with elongated structures to provide greater flexibility and control. We present a novel mathematical model, derived using Hamilton’s principle... Читать дальше...

Gender difference in domain-specific quality of life measured by modified WHOQoL-BREF questionnaire and their associated factors among older adults in a rural district in Bangladesh

Plos.org 
En

by Fakir M. Amirul Islam

Background

The global population of older adults has steadily increased in recent decades. Little is known about the gender difference in the quality of life (QoL) of older adults in the general population. This study aimed to identify factors associated with QoL among older adults by gender.

Method

Data on QoL using the World Health Organization Quality of Life (WHOQoL-BREF) questionnaire and socio-demographic characteristics, including living status and sources of income... Читать дальше...
