Cost-Effective, Hydrogen-Rich, and Ultramicroporous Metal-Organic Framework for Efficient Separation of SF from N.

It is essential for the industry to create an adsorbent that combines a high capacity with selectivity to achieve the effective separation of SF from gas mixtures. In this study, we prepared a cost-effective nickel-based metal-organic framework (MOF), Ni(BTC)(BPY), which features hydrogen-rich ultramicroporous channels specifically designed for separating SF/N gas mixtures. The findings from the adsorption experiments demonstrated that Ni(BTC)(BPY) achieved a remarkable SF adsorption capacity of 5.

One Scalable and Stable Metal-Organic Framework for Efficient Separation of CH/N Mixture.

Separating CH from coal bed methane is of great importance but challenging. Adsorption-based separation often suffers from low selectivity, poor stability, and difficulty to scale up. Herein, a stable and scalable metal-organic framework [MOF, CoNi(pyz-NH)] with multiple CH binding sites was reported to efficiently separate the CH/N mixture.

A local model based on environmental variables clustering for estimating foliar phosphorus of rubber trees with vis-NIR spectroscopic data.

Existing local models based on multiple environmental variables clustering (LM-MEVC) treat the influences of environmental factors on leaf phosphorus concentration (LPC) of rubber trees () equally when grouping samples. In fact, the effects that environmental factors assert on LPC are different. So, environmental factors need to be treated differently so that the different effects can be taken into consideration when dividing samples into clusters or groups.

RBPMS2, as a novel biomarker for predicting lymph node metastasis, guides therapeutic regimens in gastric cancer.

RNA-binding protein with multiple splicing 2 (RBPMS2) is a critical gene that encodes a member of the RNA-recognition-motif-containing protein family and is involved in the development and dedifferentiation of digestive smooth muscle cells. However, whether RBPMS2 has an effect on the prognosis of gastric cancer (GC) and its possible mechanism during GC progression remain unknown. Here, we collected 596 GC patients who underwent curative surgical resection to evaluate expression of RBPMS2.

Impacts of terrain attributes and human activities on soil texture class variations in hilly areas, south-west China.

Knowledge of soil texture variations is critical for agricultural and engineering applications because texture influences many other soil properties. This study used random forest method to evaluate the effects of human activities and topographic parameters on the spatial variability of soil texture in hilly areas where soil parent material was uniform. The study site covers 252 km and is located in the Upper Yangtze River Basin of south-west China.

Pleomorphic adenoma gene like-2 induces epithelial-mesenchymal transition via Wnt/β-catenin signaling pathway in human colorectal adenocarcinoma.

Epithelial-mesenchymal transition (EMT) is a critical step in the acquisition of metastatic and invasive power for tumor cells. Colorectal adenocarcinoma (CRC) is a common cancer where metastasis is directly linked to patient survival. Recent studies show that pleomorphic adenoma gene like-2 (PLAGL2) could induce tumor EMT and is an independent predictive factor associated with poor prognosis in cancer.

[Serum non-esterified fatty acids to albumin ratio increased significantly in children with nephrotic syndrome].

Objective: To analyze serum levels of non-esterified fatty acids (NEFA) and albumin (ALB) in children with nephrotic syndrome (NS) and investigate the clinical significance of altered serum NEFA to ALB ratio in children with NS in acute and remission phases.

Methods: Serum levels of NEFA and ALB were measured in 55 NS children in acute phase, in 33 NS children in remission and in 122 healthy control children, and the ratio of NEFA to ALB was calculated. The other lipid/lipoprotein and renal function parameters were also analyzed in these children.

Elevation of Circulating miR-210-3p in High-Altitude Hypoxic Environment.

Background: The induction of miR-210-3p, a master hypoxamir, is a consistent feature of the hypoxic response in both normal and malignant cells. However, whether miR-210-3p acts as a circulating factor in response to a hypoxic environment remains unknown. The current study aimed to examine the effect of a high-altitude hypoxic environment on circulating miR-210-3p.

Macroscopic serosal classification of colorectal cancer and its clinical significance.

Background: Macroscopic serosal classification of gastric cancer has been reported in previous studies, but rarely reported about it of colorectal cancer. The purpose of this study was to propose a macroscopic serosal classification of colorectal cancer and to investigate clinical significance of this classification.

Materials And Methods: Morphologic features of colorectal cancer were analyzed according to the macroscopic serosal appearance and clinicopathologic characteristics of these patients were retrospectively reviewed.

Influence of a high-altitude hypoxic environment on human plasma microRNA profiles.

Circulating microRNAs (miRNAs) are promising disease biomarkers. However, the influence of high-altitude hypoxic environments on plasma miRNA profiles remains unknown. This study included a total of 509 plasma samples from 278 native Tibetans and 80 newly arrived migrant Han Chinese (Tibet Han) residing at 3560 m and 151 Han Chinese residing at 8.

Expression of legumain correlates with prognosis and metastasis in gastric carcinoma.

Objective: Legumain, a novel asparaginyl endopeptidase, has been observed to be highly expressed in several types of tumors, which may play a vital role in carcinogenesis. However, there is no study investigating the relationship among Legumain expression, clinicopathologic, biological variables and patient prognosis in gastric carcinoma.

Methods: In this study, a tissue microarray (TMA) containing 282 samples of primary gastric cancer was assessed for Legumain expression by immunohistochemistry.

Prognostic impact of atypical chemokine receptor expression in patients with gastric cancer.

Background: Atypical chemokine receptors (ACRs), which serve as a decoy receptor to attract chemokines, including DARC, D6, and CCX-CKR, have an important role in inhibiting invasion and metastasis of cancer cells; however, their expression in gastric cancer has not been characterized. The purpose of this study was to determine the predictive value of ACRs for overall survival in gastric cancer.

Methods: We performed immunohistochemical analysis on formalin-fixed, paraffin-embedded cancer tissue and used Western blot analysis on cell lines with an antibody against ACR protein.

Prognostic value of tumor size in gastric cancer: an analysis of 2,379 patients.

Tumor size has been included into the staging systems of many solid tumors, such as lung and breast. However, tumor size is not integrated in the staging of gastric cancer, and its prognostic value for gastric cancer needs to be reappraised. A total of 2,379 patients who received radical resection for histopathologically confirmed gastric adenocarcinoma were enrolled in the present study.

PDCD4 functions as a suppressor for pT2a and pT2b stage gastric cancer.

Gastric cancer is one of the leading causes of cancer‑related mortality worldwide. Loss of programmed cell death 4 (PDCD4) expression has been detected in gastric cancer. However, the effects of PDCD4 on pT2 stage gastric cancer remain unclear.

Comparison different methods of intraoperative and intraperitoneal chemotherapy for patients with gastric cancer: a meta-analysis.

Purpose: To investigate the efficacy and safety of intraperitoneal chemotherapy (IPC) for patients with gastric cancer and to compare effects between different regimens of IPC.

Method: Randomized controlled trials comparing the effects of surgery plus intraperitoneal chemotherapy with surgery alone or comparing the efficacy between different regimens of intraperitoneal chemotherapy were searched for in Medline, Embase, Pubmed, the Cochrane Library and the Chinese BioMedical Disc and so on by two independent reviewers. After quality assessment and data extraction, data were pooled for meta-analysis using RevMan5.
