Mapping Chinese annual gross primary productivity with eddy covariance measurements and machine learning.

Annual gross primary productivity (AGPP) is the basis for grain production and terrestrial carbon sequestration. Mapping regional AGPP from site measurements provides methodological support for analysing AGPP spatiotemporal variations thereby ensures regional food security and mitigates climate change. Based on 641 site-year eddy covariance measuring AGPP from China, we built an AGPP mapping scheme based on its formation and selected the optimal mapping way, which was conducted through analysing the predicting performances of divergent mapping tools, variable combinations, and mapping approaches in predicting observed AGPP variations.

Effects of percutaneous vertebroplasty on respiratory parameters in patients with osteoporotic vertebral compression fractures.

Vertebral compression fractures (VCFs) often occur in patients with osteoporosis. These fractures can also lead to postural changes. Several studies have shown that patients with vertebral compression fractures have a restrictive pattern in their pulmonary function.

Exportin-T: A Novel Prognostic Predictor and Potential Therapeutic Target for Neuroblastoma.

Exportins as the key mediators of nucleocytoplasmic transport have been identified as the controllers of the passage of numerous types of crucial cancer-related proteins. Targeting exportins in cancer cells might represent an emerging strategy in cancer intervention with the potential to affect clinical outcomes. Here, we focused on the prognostic and therapeutic values of Exportin-T (XPOT) in neuroblastoma.

D-dimer/fibrinogen ratio for the prediction of progressive hemorrhagic injury after traumatic brain injury.

Background: Progressive hemorrhagic injury (PHI) greatly affects prognosis of traumatic brain injury (TBI). D-dimer/fibrinogen ratio (D/F ratio) may be a potential predictor for venous thromboembolism. This study sought to describe and evaluate any relationship between D/F ratio and PHI after TBI.

Applications of Molecular Simulation in the Discovery of Antituberculosis Drugs: A Review.

After decades of efforts, tuberculosis has been well controlled in most places. The existing drugs are no longer sufficient for the treatment of drug-resistant Mycobacterium tuberculosis due to significant toxicity and selective pressure, especially for XDR-TB. In order to accelerate the development of high-efficiency, low-toxic antituberculosis drugs, it is particularly important to use Computer Aided Drug Design (CADD) for rational drug design.

FBXW8-dependent degradation of MRFAP1 in anaphase controls mitotic cell death.

Mof4 family associated protein 1 (MRFAP1) is a 14 kDa nuclear protein, which involves in maintaining normal histone modification levels by negatively regulating recruitment of the NuA4 (nucleosome acetyltransferase of H4) histone acetyltransferase complex to chromatin. MRFAP1 has been identified as one of the most up-regulated proteins after NEDD8 (neural precursor cell expressed developmentally down-regulated 8) inhibition in multiple human cell lines. However, the biological function of MRFAP1 and the E3 ligase that targets MRFAP1 for destruction remain mysterious.

Generation of a sub-diffraction hollow ring by shaping an azimuthally polarized wave.

The generation of a sub-diffraction optical hollow ring is of great interest in various applications, such as optical microscopy, optical tweezers, and nanolithography. Azimuthally polarized light is a good candidate for creating an optical hollow ring structure. Various of methods have been proposed theoretically for generation of sub-wavelength hollow ring by focusing azimuthally polarized light, but without experimental demonstrations, especially for sub-diffraction focusing.

Wnt/β-catenin signaling inhibits FBXW7 expression by upregulation of microRNA-770 in hepatocellular carcinoma.

FBXW7 (F-box and WD repeat domain-containing 7) is the F-box protein component of a Skp1-Cul1-F-box protein-type (SCF-type) ubiquitin ligase. Previous studies have shown that FBXW7 serves as a tumor suppressor and is frequently downregulated in many types of human neoplasms. However, the molecular mechanisms for its downregulation remain poorly understood.

Regulation of β-catenin transcription activity by leupaxin in hepatocellular carcinoma.

In human cancers, β-catenin is accumulated in the nucleus and activates mRNA transcription of many oncogenic genes, such as cyclin D1 and c-myc. However, the mechanism of β-catenin-mediated transcriptional activation remains largely unknown. In the present study, we identified leupaxin, an adaptor protein sharing homology with the focal adhesion protein, as a novel coactivator for β-catenin in human hepatocellular carcinoma (HCC).

[Experimental Conditions of Laser Induced Breakdown Spectroscopy of Metal Elements in Cement].

Laser induced breakdown spectroscopy (LIBS) is a widely used material element detection technology. Because of its detection result is affected by many factors, and therefore, analysing and comparising the different experimental conditions have important significance for LIBS. Experimental sample produced by Beichuan County, Sichuan Province, China, which is ordinary Portland cement P.

Catheter-related infection and pathogens of umbilical venous catheterization in a neonatal intensive care unit in China.

We studied the incidence of umbilical venous catheterization (UVC)-related infection and pathogens in a neonatal intensive care unit (NICU) in China. Patients were grouped into <2000-g UVC or <2000-g non-UVC groups or ≥2001-g UVC or ≥2001-g non-UVC groups. Blood culture and umbilical root skin swab culture were taken following UVC insertion and extraction.

[Study on fluorescence measurement system of wastewater treatment process].

The present paper, focusing on the relationship between the fluorescence characteristics of fluorescent substances produced by the anaerobic reactors in process of the wastewater treatment status, aims to build an online detection platform of anaerobic wastewater treatment process for the wastewater treatment process parameter control, to provide effective, credible and stable technical basis, and to a certain extent can improve the efficiency of wastewater treatment. The results showed that it is feasible for this system to use fluorescence spectroscopy of wastewater treatment anaerobic reactor during the test; compared with the conventional detection method, it has simple structure, high sensitivity, and less time-consuming advantages; for other fluorescent substances in waste water treatment, it has broad application prospects.
