Impaired autophagy in macrophages accompanies the progression of atherosclerosis and contributes to lipid loading in plaques and ineffective lipid degradation. Therefore, evoking autophagy and its associated cholesterol efflux may provide a therapeutic treatment for atherosclerosis. In the present study, berberine-mediated sonodynamic therapy (BBR-SDT) was used to induce autophagy and cholesterol efflux in THP-1 macrophages and derived foam cells. Following BBR-SDT, autophagy was increased in the macrophages, autophagy resistance in the foam cells was prevented, and cholesterol efflux was induced...

Dong He, Guolong Liu, Anqi Pang, Yang Jiang, Hui Suo, Chun Zhao
Tremella-like nickel oxalate@nickel oxide (NiC2O4@NiO) core/shell hierarchical nanostructures have been successfully synthesized on nickel foam, using Ni foam as a current collector, a Ni source and a three-dimensional (3D) substrate, through a facile hydrothermal method followed by an electrochemical activation process. The prepared samples can be directly used as binder-free electrodes for supercapacitors. The tremella-like morphology, together with the NiC2O4 nanoblocks on 3D Ni foam, significantly increases the amount of active sites for redox reactions and the conductivity of the electrode material, shortens the diffusion pathway for ions, facilitates the effective penetration of the electrolyte, and lowers the intrinsic equivalent series resistance, demonstrating good potential for energy storage application...

In this work, we report the development of well-ordered hydrogenated CoMoO4 (H-CoMoO4) and hydrogenated Fe2O3 (H-Fe2O3) nanoplate arrays on 3D graphene foam (GF), and explore their practice application as binder-free electrodes in assembling flexible all-solid-state asymmetric supercapacitor (ASC) device. Our results show that the monolithic 3D porous GF prepared by solution casting method using Ni foam template possesses large surface area, superior electrical conductivity, and sufficient surface functional groups, which not only facilitate in situ growth of CoMoO4 and Fe2O3 nanoplates on it, but also contribute the double-layer capacitance of resultant supercapacitor...

Water splitting is of paramount importance for exploiting renewable energy conversion and storage systems, but is greatly hindered by the kinetically sluggish oxygen evolution reaction. Here, we develop a three-dimensional, greatly efficient and durable NiFe/Cu2O nanowires/Cu foam anode (NiFe/Cu2O NWs/CF) for water oxidation in 1.0 M KOH. The obtained electrode exhibited a current density of 10 mA/cm2 at a uniquely low overpotential of 215 mV and can keep a steady current density of 100 mA/cm2 for 50 h at an overpotential of 260 mV...

BACKGROUND AND AIMS: Laparoscopic resection is a well-established approach for colorectal cancer surgery. In patients with rectal cancer treated by neoadjuvant chemoradiotherapy, it may be difficult to identify a clear safety margin for endostapling and subsequent anastomosis. We designed an innovative technical approach to assist colorectal anastomosis in these patients. TECHNIQUE: A four-trocar laparoscopic approach is used. After exploration of the abdominal cavity, the left colic flexure is completely mobilized...

Aqueous film-forming foams (AFFFs), containing per- and polyfluoroalkyl substances (PFASs), are released into the environment during response to fire-related emergencies. Repeated historical applications of AFFF at military sites were a result of fire-fighter training exercises and equipment testing. Recent data on AFFF-impacted groundwater indicates that ~25% of the PFASs remain unidentified. In an attempt to close the mass balance, a systematic evaluation of 3M and fluorotelomer-based AFFFs, commercial products, and AFFF-impacted groundwaters from 15 U...

We present an overview of the common types of tubal patency tests, with a focus on hysterosalpingo-foam sonography (HyFoSy). Current evidence suggests that HyFoSy is an accurate alternative to X-ray hysterosalpingography (HSG) for outpatient tubal evaluation in women who are at low risk for tubal disease. It may be superior to saline hysterosalpingo-contrast sonography (HyCoSy) in excluding tubal occlusion. A hyperechogenic medium may enhance contrast visualization and enable clearer delineation of tubal anatomy...

Polyhedral tilings are often used to represent structures such as atoms in materials, grains in crystals, foams, galaxies in the universe, etc. In the previous paper, we have developed a theory to convert a way of how polyhedra are arranged to form a polyhedral tiling into a codeword (series of numbers) from which the original structure can be recovered. The previous theory is based on the idea of forming a polyhedral tiling by gluing together polyhedra face to face. In this paper, we show that the codeword contains redundant digits not needed for recovering the original structure, and develop a theory to reduce the redundancy...

Stockpiles of perfluoro-octane sulfonic acid (PFOS) containing aqueous film-forming foam (AFFF) have the potential to be emitted by leaching, spills, and during use in fire response and other processes. Several studies have discussed the high levels of stockpiled PFOS-containing AFFF and the risk they pose to the environment; however, there are large gaps in the amounts in Japan compared with other countries. For example, 300 tons are stockpiled in Canada, 2200-2600 tons in Switzerland, 1400 tons in Norway, and 19,000 tons in Japan from their reports for publication...

The commercial polyurethane foam was acid modified to get an inexpensive adsorbent (AM-PUF) has highly surface polarity and sorption capacity. The elemental analysis, scanning electron microscopy, thermal analysis, ultraviolet/visible/infrared spectroscopies and X-ray diffraction were used for characterization of AM-PUF. The surface of AM-PUF has amorphous character (broadband at 2θ, 21.75°) and contains several active sites e.g. NH, OH, CO, CC and COC groups. The electrical conductivity (σ), iodine value and methylene blue index of AM-PUF are 1...

Bin Huang, Suk-Hwan Baek
Ubiquitination is a versatile post-translational modification involved in NF-κB activation of TLR signaling. Here, we demonstrated that Trim13, an E3 ubiquitin ligase, is up-regulated in macrophages upon stimulation with TLR2 ligand. Knock-down of Trim13 attenuated TLR2-mediated production of cytokines/chemokines and formation of foam cells, as well as activation of NF-κB. Trim13 interacts with TRAF6 and potentiates NF-κB activity via ubiquitination of TRAF6. Overexpression of inactive mutant (C10/13A) or RING deletion mutant of Trim13 did not potentiate ubiquitination of TRAF6 or activation of NF-κB...
