With the onset of the 5G era, wearable flexible electronic devices have developed rapidly and gradually entered the daily life of people. However, the vast majority of research focuses on the integration of functions and performance improvement, while ignoring electromagnetic hazards caused by devices. Herein, the 3D double conductive networks are constructed through a repetitive vacuum‐assisted dip‐coating technique to decorate the 2D MXene and 1D silver nanowires on the melamine foam. Benefiting from the unique porous structure and multi‐scale interconnected frame, the resultant composite foam exhibited high electrical conductivity, low density, superb electromagnetic interference shielding (48.32 dB), and Joule heating performance (up to 90.8 °C under 0.8 V). Furthermore, a single‐electrode triboelectric nanogenerator (TENG) with powerful energy harvesting capability is assembled by combining the composite foam with an ultra‐thin Ecoflex film and a polyvinylidene fluoride film. Simultaneously, the foam‐based TENG can also be considered a reliable wearable sensor for monitoring activity patterns in different parts of the human body. The versatility and scalable manufacturing of high‐performance composite foams will provide new design ideas for the development of next‐generation flexible wearable devices. [ABSTRACT FROM AUTHOR]

Developing flexible electromagnetic wave (EMW) absorption materials with excellent mechanical properties has attracted widespread attention to eliminate the ever-growing electromagnetic radiation affecting human health and environmental safety. In this regard, we reported a mechanically robust composite aerogel film with a porous multilayered structure assisted by one-dimensional aramid nanofibers and Ni nanochains, and two-dimensional MXene (Ti3C2Tx) nanosheets, which was fabricated via one-step vacuum-assisted filtration and subsequent freeze-drying. Profiting from the effective electric/magnetic cooperative network with multiple conductive pathways as well as porous laminar microstructures, the composite aerogel film simultaneously achieved an excellent tensile strength of 30 MPa and a minimum reflection loss value of −48.6 dB at a thin thickness of 1.5 mm. Impressively, the corresponding effective absorption bandwidth reached 5.8 GHz, almost covering the entire Ku band. Besides, increasing the mass loading of Ni nanochains could endow the as-prepared composite aerogel film with enhanced EMW absorption performances to satisfy the practical requirements for electromagnetic protection applications. In this work, a porous multilayered aerogel film with an electromagnetic synergistic effect is proposed as a promising strategy for designing high-performance EMW absorbers. [ABSTRACT FROM AUTHOR]

Ethnopharmacological Relevance: Cognitive impairment caused by central neuropathy in type 2 diabetes mellitus (T2DM), namely diabetes-associated cognitive decline (DACD), is one of the common complications in patients with T2DM. Studies have shown that brain β-amyloid (Aβ) deposition is a typical pathological change in patients with DACD, and that there is a close relationship between intestinal microorganisms and cognitive impairment. However, the specific mechanism(s) of alteration in Aβ metabolism in DACD, and of the correlation between Aβ metabolism and intestinal microorganisms remain unknown., Aim of the Study: Revealing the mechanism of ZBPYR regulating Aβ metabolism and providing theoretical basis for clinical evaluation and diagnosis of DACD., Materials and Methods: We characterized Aβ metabolism in the central and peripheral tissues of Zucker diabetic fatty (ZDF) rats with DACD, and then explored the preventive and therapeutic effects of ZiBu PiYin Recipe (ZBPYR). Specifically, we assessed these animals for the formation, transport, and clearance of Aβ; the morphological structure of the blood-brain barrier (BBB); and the potential correlation between Aβ metabolism and intestinal microorganisms., Results: ZBPYR provided improvements in the structure of the BBB, attenuation of Aβ deposition in the central and peripheral tissues, and a delay in the development of DACD by improving the expression of Aβ production, transport, and clearance related protein in ZDF rats. In addition, ZBPYR improved the diversity and composition of intestinal microorganisms, decreased the abundance of Coprococcus, a bacterium closely related to Aβ production, and up regulate the abundance of Streptococcus, a bacterium closely related to Aβ clearance., Conclusion: The mechanism of ZBPYR ability to ameliorate DACD may be closely related to changes in the intestinal microbiome., Competing Interests: Declaration of Competing Interest The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024.

Background: Colon cancer, or colorectal cancer (CRC), is a type of cancer that develops from large bowel. Previous data has demonstrated that microRNAs (miRNAs) may be involved in the formation and progression of CRC. The deregulation of miR-708 has been identified in multiple types of cancer. However, to the best of our knowledge, there are no data concerning the expression and role of miR-708 in CRC., Methods: In this study, RT-PCR and Flow Cytometry were used to examine the expression and role of miR-708 and ZEB1 in proliferation and apoptosis. Transwell was used to examine the role of miR-708 and ZEB1 in invasion and migration. Western blot and qRT-PCR were conducted to determine the alteration of protein and miR-708 levels, respectively., Results: MiR-708 was significantly downregulated in CRC tissues and cell lines. The restoration of the expression of miR-708 suppressed cell proliferation, induced apoptosis, and reduced metastasis in CRC in vitro . Additionally, bioinformatics analysis predicted ZEB1 as a novel target gene of miR-708. Furthermore, ZEB1 was upregulated in CRC, which was negatively correlated with miR-708 expression. Further studies showed that the overexpression of miR-708 and silence of ZEB1 inhibited stage of CRC via inhibiting AKT/mTOR signaling pathway in CRC cells., Conclusion: Taken together, these results indicate that miR-708 plays an important role in suppressing the development of CRC by directly targeting ZEB1 through AKT/mTOR signaling pathway, suggesting that miR-708 is a novel, effective therapeutic target for treating patients with CRC., Competing Interests: None., (AJTR Copyright © 2019.)
