Developing an accurate, sensitive and visual strategy for quickly identifying biomarkers α-ketoglutaric acid (α-KA) is crucial for early disease diagnosis. Herein, we introduce a new fluorescence material, Eu@COMOC-4, synthesized by post-synthesis modification of a lanthanide-functionalized metal-organic frameworks (MOFs). This material serves as a visual fluorescence sensor to detect α-KA, with a distinct fluorescence response.

It has been found that stretching rate, temperature, and electric field have significant effects on the stress-strain relations of DEs, which may result in the failure of DEs in their applications. Thus, this paper aims to develop a thermo-electro-viscoelastic model for DEs at finite deformation and simulate the highly nonlinear stress-strain relations of DEs under various thermo-electro-mechanical loading conditions.

All of the complexes were characterized by spectroscopic methods, elemental analyses and single-crystal X-ray diffraction, and complexes 1a and 1c were additionally characterized by NMR spectroscopy. As proof of principle of their activity, these complexes were used as precatalysts for the hydroboration of esters using HBpin as the hydride source displaying high activity under neat and room temperature conditions.

Motivated by this, we evaluate the economic impacts of COVID-19 outbreak on both national and industrial levels by employing quarterly computable general equilibrium (CGE) model.

In this study, the effect of atmospheric pressure cold plasma on respiratory inflammation and oxidant stress is explored. Tunicamycin was used to stimulate human bronchial epithelial cells (HBECs) and A549 cells for inflammatory response and oxidative stress, followed by atmospheric pressure cold plasma treatment.

Objective: To assess the role of CCR10 in innate lymphoid cells (ILCs) response in radiation-induced skin damage.
Material And Methods: CCR10 and CCR10 mice were treated with either a single dose of 5 Gy or 5 Gy everyday for 6 days with a total dose of 30 Gy with X-ray. ILCs from the skin were isolated and analyzed by flow cytometry 3 and 10 days after irradiation.
Surficial sediments were collected from five sampling sites in the mainstream of the Shiwuli River along an urban-rural gradient in the Chaohu Lake basin during July 2017 (summer) and January 2018 (winter). The total uptake (SPU), abiotic uptake (SPU), and biotic uptake (SPU) of phosphorus by sediments were measured, and uptake responses to different carbon sources (i. e.

Mesencephalic astrocyte-derived neurotrophic factor exerts an antiapoptotic effect for multiple cell types. However, the correlation between MANF and atrial apoptosis in AF is still undefined.

Sediment phosphorus fractions were investigated, and equilibrium phosphate concentration (EPC) and its response to exogenous carbon (sodium acetate) addition were explored. Moreover, the risk of phosphorus release from sediment into water column was also evaluated.

The MIMO system adopts a low pulse repetition frequency (PRF) to avoid a range ambiguity for the wide-range swath and in azimuth adopts the multi-channel method to achieve azimuth high resolution from the unambiguous azimuth wide-spectrum signal, processed through adaptive digital beam-forming technology. Simulations and analytical results are presented.

Methods: We determined the content of curcumin by HPLC from different processed products of Curuma kwangsiensis and studied the anti-tumor effects in vivo by establishing S180 transplanted tumors model in mice.
Results: The content of curcumin in different processed products of Curuma kwangsiensis as follows: primitive > vinegar-fried > vinegar-cooked.
Objective: To approach the naphtha analysis of different processed products of Rhizoma Curcumae from Guangxi.
Methods: The naphtha was extracted by steam distillation. The relative content of every compound was determined with area normalization method and the structures were elucidated by GC-MS technique.
Lung cancer is one of the leading causes of death with one of the lowest survival rates. However, a subset of lung cancer patients who are of Asian origin and carry somatic mutations in epidermal growth factor receptor or EGFR have responded remarkable well to two tyrosine kinase inhibitors, gefitinib and erlotinib. While EGFR mutation profiles have been reported from Japan, South Korea, and Taiwan, there is no such report from mainland of China where the largest pool of patients reside.
