Thermogravimetric and spectroscopic analyses along with the kinetic modeling of the pyrolysis of phosphate tailings.

The present study aimed to understand the pyrolysis characteristics of phosphorus tailings and promote the resource utilization of phosphorus tailings. Thermogravimetry was combined with Fourier transform infrared spectroscopy-Raman spectroscopy-mass spectrometry (TG-FTIR-RS-MS) and kinetic models to investigate the possible reaction mechanisms during the pyrolysis of phosphorus tailings and the changes in the release characteristics of pyrolysis volatiles. The results showed that the pyrolysis process occurred in three different stages.

Novel Utilization of Terminators in the Design of Biologically Adjustable Synthetic Filters.

Terminators, which signal the end of transcription processes, are typically placed behind the last coding sequence of an operon to prevent interference between transcript units in most biologically synthetic systems. Here, we seek to extend the usability of terminators in genetic system design by using terminators as regulatory genetic parts. Terminators with different impacts on their upstream and downstream genes are characterized in detail via dynamic modeling to predict the behavior of the overall genetic system.

Association of plasma total and high-molecular-weight adiponectin with risk of colorectal cancer: an observational study in Chinese male.

The research is to investigate the association between plasma concentrations of total and high-molecular-weight (HMW) adiponectin and risk of early and advanced colorectal cancer. One hundred and sixty-five male colorectal cancer patients and one hundred and two controls were enrolled; based on the T factor of the TNM system, intraepithelial carcinoma and submucosally invasive carcinoma were defined as early cancer, and invasion into the muscularis propria or deeper was defined as advanced cancer. The plasma levels of glucose, fasting insulin, total cholesterol, triglyceride, and total and HMW adiponectin levels were measured.
