Features of the Design and Manufacturing Techniques of Frictional Disks of Caterpillar and Wheel Cars

Механика машин, механизмов и материалов, 2016
Most often meeting reason of failure while in service frictional brakes and frictional knots in caterpillar and wheel cars is deformability of frictional disks. Deformability of disks leads to indistinct inclusion and deenergizing of the frictional knot,

Histone Modification Complex JMJ704‐HDA709 Negatively Regulates Salinity Tolerance in Rice

Advanced Science, EarlyView.
This study reveals that the rice histone demethylase JMJ704 interacts with HDA709―a H3K9ac deacetylase characterized herein―to form a chromatin‐modifying complex. Under salt stress, OsWRKY72 recruits this complex through interaction with JMJ704 to target loci, repressing the expression of oxidative stress and salt‐responsive genes via removal of ...

Braking Pattern Impact on Brake Fade in an Automobile Brake System

Journal of Engineering Sciences, 2019
The importance of brake systems in automobiles cannot be overemphasized. Brakes are used in speed control of vehicles and do so by the conversion of kinetic energy into thermal energy. Better stopping performance has favored the disc brake system over the drum brake system and has found wide application in high-performance vehicles.

Engineered Exosomal miR‐146a‐5p Reprograms BMSC Fate and Restores Mitochondrial Homeostasis in Glucocorticoid‐Induced Osteonecrosis of Femoral Head

Advanced Science, EarlyView.
Exosomal miR‐146a‐5p is identified as a pivotal regulator in steroid‐induced osteonecrosis. Its reduction activates NF‐κB signaling, compromises mitophagy, and disrupts mitochondrial bioenergetics, resulting in autophagic disequilibrium. Engineered exosomes delivering miR‐146a‐5p reinstate mitochondrial function, augment oxidative phosphorylation and ...

A Dual‐Phase Exosomal Nanotherapy Enhances Continual Efferocytosis by Coordinating Checkpoint Inhibition and Metabolic Reprogramming in Atherosclerosis

Advanced Science, EarlyView.
Here we developed Am@SExo, a dual‐functional engineered exosome that coordinates CD47–SIRPα checkpoint blockade with Arg1 mRNA–mediated metabolic reprogramming. Surface SIRPα promotes recognition of apoptotic cells and plaque targeting, while Arg1 expression enhances arginine–ornithine metabolism, Rac1 activation, and actin remodeling in macrophages ...

Single‐Cell Reveal GALNT7‐Dependent Ferroptosis Suppression as a Mechanism of Immunotherapy Resistance in Non‐Small Cell Lung Cancer

Advanced Science, EarlyView.
Integrated clinical and mechanistic analyses identify GALNT7 as a ferroptosis‐suppressive regulator associated with immunotherapy resistance in non‐small cell lung cancer. GALNT7 depletion promotes lipid peroxidation, mitochondrial dysfunction, and ferroptosis, enhances CD8+ T‐cell activation and IFN‐γ production, and sensitizes tumors to PD‐1 blockade,

A Biomimetic Dual‐Targeting Nano‐APA‐Editor Reprograms the 3'UTR Landscape for Tongue Squamous Cell Carcinoma Therapy

Advanced Science, EarlyView.
This study unveils a pathogenic axis in oral cancer where NUDT21 suppresses a tumor suppressor network, prominently PTEN, via 3'UTR lengthening. To exploit this transcriptomic vulnerability, we developed a biomimetic Nano‐APA‐editor. By delivering CRISPR/Cas9, we reprogrammed the global 3'UTR landscape, restoring multi‐target tumor suppression and ...

Research on Braking Vibration Characteristics of Grooved Brake Interface of Disc Brake

IOP Conference Series: Materials Science and Engineering, 2019
Abstract With the good performance and wide application of surface texture in various aspects, more and more scholars are devoted to investigating the effect of texture interface on tribological properties. Disc brake friction pair is a typical friction brake interface.

Inhibition of KDEL Receptors Remodels the Tumor Microenvironment for T Cell Independent Tumor Regression

Advanced Science, EarlyView.
Inhibition of KDELR2 in a small fraction of tumor cells generates sustainable immunogenic cell death conditions within the tumor microenvironment. These conditions promote the regression of tumors in a T cell independent manner. During regression, macrophages prime T cells that subsequently provide systemic protection against recurrence. The potency of
