Mechanical Stress Induced NOX2 Promotes Endothelial Dysfunction in Ventilator‐Induced Lung Injury: Potential Treatment with Quercetin [PDF]

open access: yesAdvanced Science
Mechanical ventilation (MV) is a treatment that helps people who are unable to breathe on their own. However, the use of MV leads to the development of ventilator‐induced lung injury (VILI). Here, it is found that VILI with endothelial barrier disruption

Influence of Feed Motion on Surface Friction of AISI 1045 Steel Machined by a Fine-Grinding Process

open access: yesTribology in Industry, 2021
Fine-grinding is a final machining method used to reach the low friction and high-quality surface. The workspeed (vw) and crossfeed (vc) motions are perpendicular to each other and differ in value during the grinding process. Thus, the surface quality in

Influence of Humid Air Temperature on Friction Behavior in Pneumatic Cylinder

open access: yesTribology in Industry, 2021
In the air, water vapor always exists and impacts directly on the friction surface between the piston rod and the rod seal. Water vapor in the air forms moisture film on the surface of the piston rod. In some cases, it plays a role as a lubricant.

Microtubule stabilization promotes the synthesis of type 2 collagen in nucleus pulposus cell by activating hippo-yap pathway

open access: yesFrontiers in Pharmacology, 2023
Intervertebral disc degeneration (IDD) is the cardinal pathological mechanism that underlies low back pain. Mechanical stress of the intervertebral disc may result in a change in nucleus pulposus cells state, matrix degradation, and degeneration of the ...
