Super Tough Multifunctional MXene/PAA-CS Double Network Hydrogels with High Mechanical Sensing Properties and Excellent EMI Shielding Performance.

Hydrogels present significant potential in flexible materials designed for electromagnetic interference (EMI) shielding, attributed to their soft, stretchable mechanical properties and water-rich porous structures. Unfortunately, EMI shielding hydrogels commonly suffer from low mechanical properties, deficient fracture energy, and low strength, which limit the serviceability of these materials in complex mechanical environments. In this study, the double network strategy is successfully utilized along with the Hofmeister effect to create MXene/PAA (polyacrylic acid)-CS (chitosan) hydrogels and further strengthen and toughen the gel with (NH)SO solution.

This study aimed to observe and detect the relationship between CD146 expression and endothelial cells and to explore the role and possible mechanism of CD146 promoting endothelial-mesenchymal transition in RIF.

Black phosphorus nanoplatform coated with platelet membrane improves inhibition of atherosclerosis progression through macrophage targeting and efferocytosis.

Plaque rupture in atherosclerosis (AS) is a major cause of acute cardiovascular events. Macrophage-induced inflammatory responses and accumulation of excess reactive oxygen species (ROS) primarily induce unstable plaques. Therefore, targeting ROS clearance and functional modulation of macrophages are clinically crucial for improving plaque stability and inhibiting AS progression.

Integrated colon microbiome and metabolomics to elucidate the antidepressant mechanisms of the Radix Bupleuri-Radix Paeoniae Alba herb pair.

Radix Bupleuri-Radix Paeoniae Alba herb pair (RB-RPA) is the fundamental medication combination of many classic antidepressant prescriptions, and RB-RPA's antidepressant effect is well established. For an extended period, the involvement of intestinal flora in the progression of depression has been widely acknowledged. However, it remains unclear whether RB-RPA could modulate intestinal microbiota disturbances and metabolic abnormalities induced by depression.

Integrating Multiple Hierarchical Parameters to Achieve the Self-Compensation of Scale Factor in a Micro-Electromechanical System Gyroscope.

The scale factor of thermal sensitivity serves as a crucial performance metric for micro-electromechanical system (MEMS) gyroscopes, and is commonly employed to assess the temperature stability of inertial sensors. To improve the temperature stability of the scale factor of MEMS gyroscopes, a self-compensation method is proposed. This is achieved by integrating the primary and secondary relevant parameters of the scale factor using the partial least squares regression (PLSR) algorithm.

Renalase protects against podocyte injury by inhibiting oxidative stress and apoptosis in diabetic nephropathy.

Diabetic nephropathy (DN) presents a significant public health challenge due to its high rate of incidence and severe health consequences. Renalase has been identified as having renal-protective properties. A key contributor to albuminuria in DN patients is podocyte loss.

Polar coded SCMA-OCDM based on chaotic scrambled SLM.

In this work, the polar coded sparse code multiple access (SCMA) scheme based on chaotic scrambled selective mapping (CS_SLM) is proposed for future passive optical networks (PONs). The original bits are coded by polar and mapped into constellation symbols by sparse code. Then orthogonal chirp division multiplexing (OCDM) modulation is adopted which has better anti-interference ability than orthogonal frequency division multiplexing (OFDM).

Primary osteosarcoma of the kidney: A case report.

Primary renal osteosarcoma is an exceedingly rare subtype of renal malignancy, noted for its aggressive nature and often fatal outcome. The scarcity and severity of this condition have resulted in a dearth of reliable methods for early diagnosis and effective treatment. The present article contributes to the existing body of knowledge by presenting a comprehensive clinical case of a 46-year-old male patient with primary renal osteosarcoma.

Simultaneously blocking ANGPTL3 and CD47 prevents the progression of atherosclerosis through regulating lipid metabolism, macrophagic efferocytosis and lipid peroxidation.

Atherosclerosis (AS) ultimately cause major adverse cardiovascular events (MACEs). While traditional strategies by lipid-reducing have reduced MACEs, many patients continue to face significant risks. It might attribute to the upregulation of CD47 expression in AS lesions, that mediated anti-efferocytosis of macrophages.

Identifying the gene responsible for non-photochemical quenching reversal in Phaeodactylum tricornutum.

Algae such as diatoms and haptophytes have distinct photosynthetic pigments from plants, including a novel set of carotenoids. This includes a primary xanthophyll cycle comprised of diadinoxanthin and its de-epoxidation product diatoxanthin that enables the switch between light harvesting and non-photochemical quenching (NPQ)-mediated dissipation of light energy. The enzyme responsible for the reversal of this cycle was previously unknown.
