[Spectral Characteristics of Dissolved Organic Matter in the Yangtze River Basin and Its Response to Natural and Anthropogenic Activities].

Dissolved organic matter （DOM） is involved in many biogeochemical processes and plays an important role in aquatic ecosystems. Notable differences appear in land use types in the upper, middle, and lower reaches of the Yangtze River, and the distribution characteristics and optical properties of DOM and its response to natural and anthropogenic activities vary greatly in long-distance transport. This study systematically collected 84 water samples from the upper, middle, and lower reaches of the Yangtze River Basin and used ultraviolet-visible spectroscopy （UV-vis）, three-dimensional fluorescence spectroscopy combined with fluorescence region integration （FRI）, and parallel factor analysis （PARAFAC） to analyze the distributional and compositional characteristics of DOM in the Yangtze River Basin and to explore the response of DOM to natural and anthropogenic activities.

FL% is associated with the severity of acute DeBakey type I aortic dissection in patients undergoing frozen elephant trunk and total arch replacement.

Objectives: The diameter, area, and volume of the true lumen and false lumen (FL) have been measured in previous studies to evaluate the extent of DeBakey type I aortic dissection. However, these indicators have limitations because of the irregular shapes of the true and false lumens and the constant oscillation of intimal flap during systole and diastole. The ratio of arch lengths seems to be a more reliable indicator.

The 18 recipients were followed up until June 31, 2022.

Effects of electrostatic interactions on global folding and local conformational dynamics of a multidomain Y-family DNA polymerase.

The Y-family DNA polymerases specialize in translesion DNA synthesis, which is essential for replicating damaged DNA. The Y-family polymerases, which are made up of four stable domains, exhibit extensive distributions of charged residues, and are responsible for the tight formation of the protein-DNA complex. However, it is still unclear how the electrostatic interactions influence the conformational dynamics of the polymerases.

Knockdown of miR-543 Inhibits the Proliferation and Migration of Small-Cell Lung Carcinoma Cells and Induces Apoptosis.

This article aims to explore the effects and possible mechanism of miR-543 on small-cell lung carcinoma (SCLC) cells. The respective levels of miR-543 in lung carcinoma tissues, para-cancerous tissues, human normal lung cells MRC-9, and SCLC cells were detected by RT-qPCR. The proliferation, apoptosis, and migration of SCLC cells were detected after the miR-543 level in SCLC cells was altered by miRNA mimics and inhibitors.

Impact of ball-milling and ionic liquid pretreatments on pyrolysis kinetics and behaviors of crystalline cellulose.

In this work, the kinetic mechanisms of pyrolysis of cellulose with different physical structures were illustrated. The crystalline cellulose showed better thermal stability and required higher energy for decomposition with more concentrated reactions due to the highly ordered structure. The crystallinity of the ball milling and ionic liquid pretreated cellulose decreased and the structure was relatively loose and disordered, thereby reducing the thermal stability, so the global activation energy of both samples decreased and the intensive reaction caused by the collapse of structure was alleviated.

Clinical significance of reduced expression of lncRNA TUG1 in the peripheral blood of systemic lupus erythematosus patients.

Objective: To investigate the expression and clinical significance of long non-coding RNA taurine up-regulated gene 1 (lncRNA TUG1) in the peripheral blood of systemic lupus erythematosus (SLE) patients.

Methods: With the peripheral blood mononuclear cells (PBMCs: T-cells, B-cells and monocytes) collected from SLE patients and healthy controls, TUG1 expression was determined to identify the correlation with the clinicopathological features of SLE patients. Thereby, the diagnostic value of TUG1 expression in diagnosis of SLE was evaluated by receiver operating characteristic (ROC) curve analysis.

The protection of NF-κB inhibition on kidney injury of systemic lupus erythematosus mice may be correlated with lncRNA TUG1.

We aimed to know the effect of nuclear factor-kappa B (NF-κB) inhibition on the kidney injury of systemic lupus erythematosus (SLE) mice. Pristane-induced SLE mice were treated with pyrrolidine dithiocarbamate (PDTC, 50 or 100 mg/kg), a NF-κB inhibitor. Histopathological changes were observed by hematoxylin & eosin, Masson and periodic schiff-methenamine stainings.

A Printed and Flexible NO Sensor Based on a Solid Polymer Electrolyte.

Solid polymer electrolyte (SPE) is an important part of printed electrochemical gas sensors and are of value to electrochemical sensors. Here, a new type of SPE was prepared by dissolving a poly-vinylidene fluoride (PVDF) matrix in a 1-methyl-2-pyrrolidone (NMP) to immobilize 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM] [BF]), which was then used in a new electrochemical amperometric nitrogen dioxide sensor. The SPE was coated on a single electrode and attached to the electrode to construct a simple two-layer structure.

Single-center study on transplantation of livers donated after cardiac death: A report of 6 cases.

Effective use of all available donated organs is critical, in order to meet the increasing demand for transplants. The present study explored liver transplantation with livers that were donated following cardiac death (DCD). According to the guidelines established by The Red Cross Society of China, 42 DCD organs were procured.

Tailoring electromagnetically induced transparency with different coupling mechanisms.

Tailoring electromagnetically induced transparency with two different coupling mechanisms has been numerically demonstrated. The results show that EIT based on simultaneous electric resonance and magnetic resonance has relatively larger coupling distance compared with that based on electric resonance near field coupling to magnetic resonance. The relatively large coupling distance is due to the relatively small susceptibility change.

Seroprevalence of Encephalitozoon cuniculi and Toxoplasma gondii in domestic rabbits (Oryctolagus cuniculus) in China.

The breeding of domestic rabbits (Oryctolagus cuniculus) for human consumption has a long tradition in China. Infections that can affect the production of meat or even be transmitted from animals to humans are important to monitor, especially for public health reasons as well as for their impact on animal health. Thus, a total of 1,132 domestic rabbit sera from 4 regions in China were collected for serological screening for Encephalitozoon cuniculi and for Toxoplasma gondii by ELISA and modified agglutination test (MAT), respectively.
