Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

open access: yesFEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

A picogram and nanometer scale photonic crystal opto-mechanical cavity [PDF]

open access: yes, 2008
We describe the design, fabrication, and measurement of a cavity opto-mechanical system consisting of two nanobeams of silicon nitride in the near-field of each other, forming a so-called "zipper" cavity.

Differential Efficacy of 2 Vibrating Orthodontic Devices to Alter the Cellular Response in Osteoblasts, Fibroblasts, and Osteoclasts

open access: yesDose-Response, 2018
Modalities that increase the rate of tooth movement have received considerable attention, but direct comparisons between devices are rare. Here, we contrasted 2 mechanical vibratory devices designed to directly transfer vibrations into alveolar bone as a

Teaching Python with team‐based learning: using cloud‐based notebooks for interactive coding education

open access: yesFEBS Open Bio, EarlyView.
This study presents a novel approach to teaching Python and bioinformatics using team‐based learning and cloud‐hosted notebooks. By integrating interactive coding into biomedical education, the method improves accessibility, student engagement, and confidence—especially for those without a computing background.

Menthol‐like cooling compounds, including (R)‐(‐)‐carvone, inhibit the human bitter taste receptors for saccharin and acesulfame K

open access: yesFEBS Open Bio, EarlyView.
We report that some menthol‐like cooling compounds, including (R)‐(‐)‐carvone, act as inhibitors of TAS2R31 and TAS2R43, which are taste receptors responsible for the intrinsic bitter aftertastes of saccharin and acesulfame K. However, there was little correlation between the intensity of the cooling sensation and the potency of bitterness inhibition ...

Steering Differential Control of Two-wheeled Direct-drive Electric Vehicle Based on Master-slave Strategy

open access: yesKongzhi Yu Xinxi Jishu, 2010
Two-wheeled direct-drive electric vehicle is driven by induction in-wheel motor, which can precisely control the in-wheel motor with the same and differential speed and take place of the mechanical differential and transmission device of traditional ...

The Diagnostic Value of Visual Evoked Potentials in Chronic Disorders of Consciousness

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In chronic disorders of consciousness (DOCs), the distinction between vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious state (MCS) is as crucial as it is challenging. Evoked potentials (EPs) and event‐related potentials (ERPs) are helpful, but some limitations prevent their consistent use in the ...

On Dynamic Stability of a Nonlinear Aeroelastic System

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2018
A nonlinear mathematical model of a device related to vibratory technology is considered. The device is intended for the intensification of technological processes, for example, the mixing process. The action of such devices is based on the vibrations of

Coulomb Blockade in a Coupled Nanomechanical Electron Shuttle

open access: yes, 2012
We demonstrate single electron shuttling through two coupled nanomechanical pendula. The pendula are realized as nanopillars etched out of the semiconductor substrate. Coulomb blockade is found at room temperature, allowing metrological applications.

Total Mechanical Unloading Minimizes Metabolic Demand of Left Ventricle and Dramatically Reduces Infarct Size in Myocardial Infarction

open access: yesPLoS ONE, 2016
Background Left ventricular assist device (LVAD) mechanically unloads the left ventricle (LV). Theoretical analysis indicates that partial LVAD support (p-LVAD), where LV remains ejecting, reduces LV preload while increases afterload resulting from the ...
