[Analysis of Ozone Pollution Characteristics and Transmission Pathways in the Main Urban Area of Urumqi].

Global climate change is becoming increasingly crucial. With the continuous strengthening of environmental supervision and governance in China, the haze （O） weather mainly caused by PM pollution has gradually improved, while the emissions of invisible ozone pollutants have been increasing annually. In particular, the problem of near-ground ozone pollution is more crucial, which poses a severe threat to urban production, life, and health of people.

Adult versus paediatric undifferentiated embryonal sarcoma of the liver: a SEER database analysis.

Background: Undifferentiated embryonal sarcoma of the liver (UESL) is a rare liver tumour that occurs mainly in children. Herein, we aimed to identify any differences in clinical characteristics and survival between adult and paediatric patients with UESL.

Methods: From 1975 to 2015 in the Surveillance, Epidemiology and End Results (SEER) database, patients diagnosed with UESL were identified and divided into paediatric (<18 years) and adult (≥18 years) groups.

Exosomal NNMT from peritoneum lavage fluid promotes peritoneal metastasis in gastric cancer.

Peritoneal metastasis (PM) is the major cause of recurrence in patients with gastric cancer (GC) and is associated with poor prognosis. The oncogenic role of Nicotinamide N-methyltransferase (NNMT) in GC has been reported, but the role of secreted NNMT that is transported by exosomes remains unknown. In this study, exosomes were isolated from GC patients with or without PM and from GC cell line, including GC-114, GC-026, MKN45, and SNU-16 cells.

Genetic map construction and QTL analysis of leaf-related traits in soybean under monoculture and relay intercropping.

Soybean (Glycine max L.) is an important food and oil crop widely planted by intercropping in southwest China. The shade caused by intercropping changes plant growth traits, such as soybean leaf and dry mass, thereby reducing yields.

PIK3R3 Promotes Metastasis of Pancreatic Cancer via ZEB1 Induced Epithelial-Mesenchymal Transition.

Background/aims: PIK3R3 is a regulatory subunit of phosphatidylinositol 3-kinase (PI3K) which plays an essential role in the metastasis of several types of cancer. However, whether PIK3R3 can promote the metastasis of pancreatic cancer (PC) is still unclear. In this study, we characterized the role of PIK3R3 in metastasis of PC and underlying potential mechanisms.

PEG10 overexpression induced by E2F-1 promotes cell proliferation, migration, and invasion in pancreatic cancer.

Background: Overexpression of paternally expressed gene-10 (PEG10) is known to promote the progression of several carcinomas, however, its role in pancreatic cancer (PC) is unknown. We investigated the expression and function of PEG10 in PC.

Methods: PEG10 expression and correlation with PC progression was assessed in cancerous tissues and paired non-cancerous tissues.

Altered expression of CD226 and CD96 on natural killer cells in patients with pancreatic cancer.

The progression of pancreatic cancer (PC) is significantly associated with tumor immune escape, which may be associated with nature killer (NK) cell dysfunction. CD226, CD96, and TIGIT, which share the ligand CD155, play important roles in the regulation of NK cell function. The present study was conducted to investigate the roles of these molecules in NK cells from PC patients.

Distribution of polychlorinated biphenyls in soil around three typical industrial sites in Beijing, China.

We investigated three locations in Beijing, China, containing different industrial plants that may cause pollution of polychlorinated biphenyls (PCBs). The highest soil concentration of 1,000 pg g(-1) (dry wt) was found in the chemical plant. The concentrations of ΣPCBs tended to decrease with distance from each of the investigated sites.

[Metabolic characteristics of air microbial communities from sandstorm source areas of the Taklamakan desert].

The aim was to compare the characteristics and the differences in carbon catabolic diversity of air samples collected from five locations that around the edge of Taklamakan desert. The characteristics and the differences of carbon metabolic profiles were detected by using the BIOLOG micro plate (BIOLOG EcoPlate). The results showed that the average well color development (AWCD) curve of all five samples did not reach clear saturation during the incubation time (10 days), but differences among them were significant.

[Recombinant human testis sperm binding protein increases sperm motility parameters].

Objective: To investigate the effects of recombinant human testis sperm binding protein (TSBP) on human sperm motility parameters in vitro.

Methods: Sperm specimens obtained from 22 healthy fertile men were prepared by the Percoll gradient-centrifugation technique. The sperm suspension was incubated with recombinant His6-TSBP at the concentration of 0.

[Genetic diversity analysis of the developed Qingke (hulless barley) varieties from the plateau regions of Sichuan Province in China revealed by SRAP markers].

Genetic diversity of 25 accessions of Qingke (hulless barley) varieties from the plateau regions of Sichuan Province, China, was analyzed by using SRAP (Sequence-related Amplified Polymorphism) markers. The results showed that 64 pairs of primer combinations produced 999 clear bands, of which 62 primer pairs (96.9%) amplified 225 polymorphic bands (22.

Analysis of bacterial community structures in two sewage treatment plants with different sludge properties and treatment performance by nested PCR-DGGE method.

The bacterial community structures in two sewage treatment plants with different processes and performance were investigated by denaturing gradient gel electrophoresis (DGGE) of nested polymerase chain reaction (nested PCR) amplified 16S rRNA gene fragments with group-specific primers. Samples of raw sewage and treated effluents were amplified using the whole-cell PCR method, and the activated sludge samples were amplified using the extracted genomic DNA before the PCR products were loaded on the same DGGE gel for bacterial community analysis. Ammonia-oxidizing bacterial and actinomycetic community analysis were also carried out to investigate the relationship between specific population structures and system or sludge performance.

Application of PCR-DGGE to analyse the yeast population dynamics in slurry reactors during degradation of polycyclic aromatic hydrocarbons in weathered oil.

Slurry-phase reactors have been used to investigate the biodegradation feasibility of polycyclic aromatic hydrocarbons (PAHs) in weathered crude oil, by mixed culture containing five PAHs-degrading yeast strains. Yeasts were isolated from the oily soil by enrichment culture, using phenanthrene as a sole carbon source, and identified based on the 26S ribosomal DNA (rDNA) sequence. Yeast strains belonged to the genera Candida, Pichia, Rhodotorula and Sporidiobolus.

[Isolation of neural stem cells from the spinal cords of human fetus.].

Neural stem cells are a potential therapeutic source for cellular transplantation therapy in neurological diseases. The present paper was aimed to investigate whether neural stem cells could be obtained from the spinal cords of low temperature preserved abortuses. Fourteen weeks old abortuses were stored in a refrigerator at 4 degrees C without any additional treatments for 2, 6 and 12 h before use.
