All-Metal Flexible Fiber by Continuously Assembling Nanowires for High Electrical Conductivity.

Fiber electronics booms as a new important field but is currently limited by the challenge of finding both highly flexible and conductive fiber electrodes. Here, all-metal fibers based on nanowires are discovered. Silver nanowires are continuously assembled into robust fibers by salt-induced aggregation and then firmly stabilized by plasmonic welding.

High-performing fiber electrodes based on a gold-shelled silver nanowire framework for bioelectronics.

Flexible fiber electrodes offer new opportunities for bioelectronics and are reliable applications, high flexibility, high electrical conductivity, and satisfactory biocompatibility are typically required. Herein, we present an all-metal flexible and biocompatible fiber electrode based on a metal nanowire hybrid strategy, , silver nanowires were assembled on a freestanding framework, and further to render them inert, they were plated with a gold nanoshell. Our fiber electrodes exhibited a low modulus of ∼75 MPa and electrical conductivity up to ∼4.

Root-exuded specialized metabolites reduce arsenic toxicity in maize.

By releasing specialized metabolites, plants modify their environment. Whether and how specialized metabolites protect plants against toxic levels of trace elements is not well understood. We evaluated whether benzoxazinoids, which are released into the soil by major cereals, can confer protection against arsenic toxicity.

Soil (microbial) disturbance affect the zinc isotope biogeochemistry but has little effect on plant zinc uptake.

Zinc (Zn) is an important micronutrient but can be toxic at elevated concentrations. We conducted an experiment to test the effect of plant growth and soil microbial disturbance on Zn in soil and plants. Pots were prepared with and without maize and in an undisturbed soil, a soil that was disturbed by X-ray sterilization and a soil that was sterilized but reconditioned with the original microbiome.

Transfusion of stored autologous blood in patients with low-grade pseudomyxoma peritonei: A retrospective analysis of its safety and outcome.

Background: Pseudomyxoma peritonei is a rare disease that presents as a malignant tumor on the peritoneal surface. Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy is the standard treatment for this disease and frequently requires a red blood cell transfusion. However, due to the limited collection and supply of allogeneic blood, surgical treatment may be delayed due to inadequate preparation of allogeneic blood in the course of clinical treatment.

Effects of endoscopic submucosal dissection on post-operative early treatment effectiveness and serum TAT-2 and GP73 expression levels in patients with early gastric cancer.

The present study aimed to explore the effectiveness of endoscopic submucosal dissection (ESD) in the treatment of early gastric cancer (EGC) and its effect on serum tumor-associated trypsin-2 (TAT-2) and Golgi protein 73 (GP73) expression levels to provide a reference for the treatment of EGC. TAT-2 is a proteolytic target enzyme for tumor-associated trypsin inhibitor that has been previously reported to enhance invasion by promoting extracellular matrix degradation. GP73 is a novel type II Golgi membrane protein of unknown function that is expressed in the hepatocytes of patients with adult giant-cell hepatitis.

Specific and conserved patterns of microbiota-structuring by maize benzoxazinoids in the field.

Background: Plants influence their root and rhizosphere microbial communities through the secretion of root exudates. However, how specific classes of root exudate compounds impact the assembly of root-associated microbiotas is not well understood, especially not under realistic field conditions. Maize roots secrete benzoxazinoids (BXs), a class of indole-derived defense compounds, and thereby impact the assembly of their microbiota.

CREB1 Suppresses Transcription of microRNA-186 to Promote Growth, Invasion and Epithelial-Mesenchymal Transition of Gastric Cancer Cells Through the KRT8/HIF-1α Axis.

Background: The cAMP response element-binding protein 1 (CREB1) was initiated as a potential target for cancer treatment. This research was conducted to probe the effect of CREB1 in the progression of gastric cancer (GC) and the molecules involved.

Materials And Methods: CREB1 expression in GC tissues and cell lines (AGS and MKN-45) as well as that in normal tissues and in gastric mucosa cell line (GES-1) was detected.

Antioxidant and Fluorescence Properties of Hydrogenolyzised Polymeric Proanthocyanidins Prepared Using SO₄/ZrO₂ Solid Superacids Catalyst.

Larix bark oligomeric proanthocyanidins (LOPC) were prepared from larix bark polymeric proanthocyanidins (LPPC) by catalytic hydrogenolysis using SO₄/ZrO₂ solid superacid as the catalyst. The catalyst to polymeric proanthocyanidins ratio was 0.2:1 (/).

Massive hemorrhagic ascites: A rare presentation of eosinophilic gastroenteritis.

According to Klein's classification system, the symptomatology of eosinophilic gastroenteritis (EG), a rare disease, differs based on the affected tissue layer. Patients with subserosal EG often have peritoneal effusion. Hemorrhagic ascites due to EG is extremely rare and has not been reported in the literature.

Widely-tunable, narrow-linewidth III-V/silicon hybrid external-cavity laser for coherent communication.

We demonstrate a III-V/silicon hybrid external cavity laser with a tuning range larger than 60 nm at the C-band on a silicon-on-insulator platform. A III-V semiconductor gain chip is hybridized into the silicon chip by edge-coupling the silicon chip through a SiN spot size converter. The demonstrated packaging method requires only passive alignment and is thus suitable for high-volume production.

Symmetrical polarization splitter/rotator design and application in a polarization insensitive WDM receiver.

In integrated photonics, the design goal of a polarization splitter/rotator (PSR) has been separating the TE0 and TM0 modes in a waveguide. This is a natural choice. But in theory, a PSR only needs to project the incoming State Of Polarization (SOP) orthogonally to its output ports, using any orthogonal mode basis set in the fiber.

We report for the first time two typical phase coherence lengths in highly confined silicon waveguides fabricated in a standard CMOS foundry's multi-project-wafer shuttle run in the 220nm silicon-on-insulator wafer with 248nm lithography. By measuring the random phase fluctuations of 800 on-chip silicon Mach-Zehnder interferometers across the wafer, we extracted, with statistical significance, the coherence lengths to be 4.17 ± 0.

An integrated laser is a key component in silicon based photonic integrated circuits. Beyond incorporating the gain medium, on-chip cavity design is critical to device performance and yield. Typical recent results involve cavities utilizing distributed Bragg gratings that require ultra-fine feature sizes.
