Spatio-temporal dynamics and sensitive distance of nighttime light environment in Pearl River Delta Protected Areas, China.

Protected areas (PAs) are important barriers to ensure the ecological security of territory. Light pollution is a threat to PAs, which is particularly obvious in the urban agglomeration environment. We used multi-source big data (satellite remote sensing light data, land cover types and points of interest) to quantitatively analyze the temporal and spatial dynamics of nighttime light in the PAs of the Pearl River Delta (PRD) urban agglomeration from 2000 to 2018, the correlation between the night light environment within the PAs and human activity intensity outside, as well as the sensitive distance of the PAs to artificial light interference.

Sputum Metabolomic Profiling Reveals Metabolic Pathways and Signatures Associated With Inflammatory Phenotypes in Patients With Asthma.

Purpose: The molecular links between metabolism and inflammation that drive different inflammatory phenotypes in asthma are poorly understood. We aimed to identify the metabolic signatures and underlying molecular pathways of different inflammatory asthma phenotypes.

Methods: In the discovery set (n = 119), untargeted ultra-high-performance liquid chromatography-mass spectrometry (UHPLC-MS) was applied to characterize the induced sputum metabolic profiles of asthmatic patients with different inflammatory phenotypes using orthogonal partial least-squares discriminant analysis (OPLS-DA), and pathway topology enrichment analysis.

Optimizing nitrogen fertilizer amount for best performance and highest economic return of winter wheat under limited irrigation conditions.

Inappropriate water and fertilizer management can lead to unstable crop yields. Excessive fertilization can potentially cause soil degradation and nitrogen (N) leaching. The aim of this study was to explore the optimal N application rate on two wheat varieties with different nitrogen responding under limited water irrigation at three experimental sites in the Piedmont plain of the Taihang Mountains, China.

Different Surface Appearances Caused by Unbalanced Mn Accumulation in Gallstones Consisting of Cholesterol and CaCO Obtained from a Patient After Cholecystectomy.

Gallstones were examined for 58 patients in Jilin, Jilin. It was found that gallstones from only one who suffered from cholecystectomy were composed of 20 spheroidal stones and they rarely exhibited three different types of surface appearances. Six representative powder samples were analyzed for gallstones compositions and Mn using X-ray diffraction (XRD)/Infrared (IR) and electron spin resonance (ESR), respectively.

Lycopene Prevents DEHP-Induced Liver Lipid Metabolism Disorder by Inhibiting the HIF-1α-Induced PPARα/PPARγ/FXR/LXR System.

Di(2-ethylhexyl) phthalate (DEHP) is a widespread pollutant that badly affects animals and human health. Lycopene (LYC) has been used as a dietary supplement that has effective antioxidant and antiobesity functions. The present goal was to understand the molecular mechanisms of LYC preventing DEHP-induced lipid metabolism of the liver.

circAFF1 Aggravates Vascular Endothelial Cell Dysfunction Mediated by miR-516b/SAV1/YAP1 Axis.

Pathological vascular endothelial damage caused by hypoxia is the basis of many vascular-related diseases. However, the role of circular RNA in hypoxic vascular injury is still poorly understood. Here, we found that hypoxia induced AFF1 circular RNA (circAFF1) can activate the SAV1/YAP1 and lead to the dysfunction of vascular endothelial cells.

Preliminary study on the correlation between the trace Mn and the calcite polymorph in gallstones containing calcium carbonate from the northeast China via electron spin resonance.

Gallstones containing calcium carbonate (GCCC) from the northeast China were analyzed using X-ray diffraction (XRD), infrared spectroscopy (IR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and electron spin resonance (ESR). The sextet signal arising from the allowed transitions of the trace Mn ions in GCCC was found to be ESR-detectable and strong. The XRD technique revealed the crystal habit of calcite in GCCC.

[Clinicopathological characteristics and prognosis of solid pseudopapillary neoplasm of the pancreas: comparison between tumors ≤5 cm and larger tumors].

Objective: To compare the clinicopathological characteristics and prognosis of patients with small (≤5 cm) solid pseudopapillary neoplasm of the pancreas (SPN) and those with large (>5 cm) SPNs.

Methods: We retrospectively analyzed the clinical characteristics, laboratory findings, radiological features, treatment and prognosis of 148 patients with histologically confirmed SPN between August, 2006 and December, 2014 and compared the data between patients with small SPNs (≤5 cm) and those with large SPNs (>5 cm).

Results: In the large SPN group, the female-to-male ratio was significantly higher than that in small SPN group (61/8 vs 56/23, P=0.

The role of extracellular-5'-nucleotidase/CD73 in glioma peritumoural brain edema.

During pathological conditions, extracellular-5'-nucleotidase/CD73 can protect neurons by reducing the permeability of the blood brain barrier. In recent years, it has been demonstrated that CD73 can negatively contribute to the growth of gliomas; however, the function of CD73 in glioma blood vessels is not clear. We analysed the expression of CD73 in 72 glioma patients using immunohistochemistry and correspondingly compared the results with the Edema index (EI).

Auxiliary partial liver transplantation for acute liver failure using "high risk" grafts: Case report.

Acute liver failure (ALF) is a reversible disorder that is associated with an abrupt loss of hepatic mass, rapidly progressive encephalopathy and devastating complications. Despite its high mortality, an emergency liver transplantation nowadays forms an integral part in ALF management and has substantially improved the outcomes of ALF. Here, we report the case of a 32-year-old female patient who was admitted with grade IV hepatic encephalopathy (coma) following drug-induced ALF.

Pure Laparoscopic Versus Open Liver Resection for Primary Liver Carcinoma in Elderly Patients: A Single-Center, Case-Matched Study.

Pure laparoscopic liver resection (PLLR) has been reported to be as safe and effective as open liver resection (OLR) for liver lesions, and it is associated with less intraoperative blood loss, shorter hospital stay, and lower complication rate. However, studies comparing PLLR with OLR in elderly patients were limited. The aim of this study was to analyze the short-term outcome of PLLR versus OLR for primary liver carcinoma (PLC) in elderly patients.
