Screening for colorectal cancer: Study on the shedding cells of feces.

Objective: The objective of this study was to explore the enrichment efficiency of an improved fecal exfoliated cell enrichment method and its application in colorectal cancer screening.

Material And Methods: Samples were collected from a cohort of 100 colorectal cancer patients being treated at the First Hospital of Hebei Medical University from January 2021 to June 2022. Patient samples were equally divided between control and experimental groups corresponding to the enrichment method being applied to the fecal exfoliated cells.

Photosynthetic oxygen-supported algal-bacterial aerobic granular sludge can facilitate carbon, nitrogen and phosphorus removal from wastewater: Focus on light intensity selection.

Photosynthetic O is a promising alternative for mechanical aeration, the major energy-intensive unit in wastewater treatment plants. This study aimed to investigate the effects of light intensity varied from 190 to 1400 µmol·s·m on photosynthetic O-supported algal-bacterial aerobic granular sludge (AGS) system. Results indicate photosynthetic O can implement aerobic phosphorus (P) uptake and ammonia oxidation under the test illumination range even at dissolved oxygen concentration < 0.

Effects of vitamin C combined with rbFGF on inflammatory factors and oxygen environment in patients with high-voltage electrical burns.

To investigate the effect of vitamin C combined with recombinant basic fibroblast growth factor (rbFGF) on inflammatory factors and oxygen environment in patients with high-voltage electrical burns. A retrospective analysis of 98 patients with high-voltage electrical burns admitted to our hospital from January 2021 to April 2022. A total of 98 patients were divided into research group and control group, including 49 cases treated with vitamin C combined with rbFGF and 49 cases treated with only rbFGF.

Leaching potential of stabilized fly ash from the incineration of municipal solid waste with a new polymer.

The presence of toxic metals in municipal solid waste incineration fly ash is of great concern due to their leaching potential in landfills. To prevent groundwater or soil contamination caused by metal leaching from fly ash, recently the Chinese government began to require that the leachate concentrations of toxic metals not only satisfied the GB 16889-2008 criteria prior to landfilling but also introduced a series of measures to monitor the groundwater quality in the landfill site and its adjacent areas (GB/T 18772-2017). The stringent hazardous waste measures for pollution control on landfill sites of municipal solid waste demand the development of more efficient chemical stabilizers.

Free-radical-initiated coupling reaction of alcohols and alkynes: not C-O but C-C bond formation.

This work demonstrates an efficient method to prepare allylic alcohols via direct C-C bond formation using electron-rich alkynes and aliphatic alcohols initiated by tert-butyl hydroperoxide.
