Nanocomposite Membrane Scaffolds for Cell Function Maintaining for Biomedical Purposes

open access: yesNanomaterials, 2021
Nanocomposite multilayered membrane coatings have been widely used experimentally to enhance biomedical materials surfaces. By the selection of reliable components, such systems are functionalized to be adjusted to specific purposes.

Intraocular pressure during handgrip exercise: The effect of posture and hypercapnia in young males

open access: yesPhysiological Reports, 2021
Purpose As part of our investigations of intraocular pressure (IOP) as a potential contributing factor to the spaceflight‐associated neuro‐ocular syndrome using the 6° head‐down tilt (6°HDT) bed rest experimental model, we compared the effect of rest and

Dynamic Bayesian networks for prediction of health status and treatment effect in patients with chronic lymphocytic leukemia

open access: yesScientific Reports, 2022
Chronic lymphocytic leukemia (CLL) is the most common blood cancer in adults. The course of CLL and patients' response to treatment are varied. This variability makes it difficult to select the most appropriate treatment regimen and predict the ...

Perception of Thermal Comfort during Skin Cooling and Heating

open access: yesLife, 2021
Due to the static and dynamic activity of the skin temperature sensors, the cutaneous thermal afferent information is dependent on the rate and direction of the temperature change, which would suggest different perceptions of temperature and of thermal ...

Investigation of reciprocating friction characteristics between different bionic surfaces of prosthesis materials and skin

open access: yesBiosurface and Biotribology, 2019
In this study, three types of bionic texture surfaces were designed, based on the microstructure of tree frog and gecko feet, for two typical prosthetic substrates: silicone rubber and thermoplastic polyurethane elastomer (TPU). The surface energy of all

Aerobic but not thermoregulatory gains following a 10‐day moderate‐intensity training protocol are fitness level dependent: A cross‐adaptation perspective

open access: yesPhysiological Reports, 2020
Moderate‐intensity exercise sessions are incorporated into heat‐acclimation and hypoxic‐training protocols to improve performance in hot and hypoxic environments, respectively. Consequently, a training effect might contribute to aerobic performance gains,

Calculation of the Gibbs–Donnan factors for multi-ion solutions with non-permeating charge on both sides of a permselective membrane

open access: yesScientific Reports, 2021
Separation of two ionic solutions with a permselective membrane that is impermeable to some of the ions leads to an uneven distribution of permeating ions on the two sides of the membrane described by the Gibbs–Donnan (G–D) equilibrium with the G–D ...

Measuring miniature eye movements by means of a SQUID magnetometer [PDF]

open access: yes, 1982
A new technique to measure small eye movements is reported. The precise recording of human eye movements is necessary for research on visual fatigue induced by visual display units.1 So far all methods used have disadvantages: especially those which are ...

EtCO2-Based Biofeedback Method of Breath Regulation Increases Speech Fluency of Stuttering People

open access: yesArchives of Acoustics, 2015
Respiratory disturbances frequently accompany stuttering. Their influence on lung ventilation can be assessed by measurement of the end-tidal CO2 concentration (EtCO2).

The amblyopic eye in subjects with anisometropia show increased saccadic latency in the delayed saccade task

open access: yesFrontiers in Integrative Neuroscience, 2014
The term amblyopia is used to describe reduced visual function in one eye (or both eyes, though not so often) which cannot be fully improved by refractive correction and explained by the organic cause observed during regular eye examination.
