Usefulness of analyzing endoscopic features in identifying the colorectal serrated sessile lesions with and without dysplasia.

Background: Sessile serrated lesions (SSLs) are often missed on colonoscopy, and studies have shown this to be an essential cause of interstitial colorectal cancer. The SSLs with dysplasia (SSL-D), in particular, have a faster rate of carcinogenesis than conventional tubular adenomas. Therefore, there is a clinical need for some endoscopic features with independent diagnostic value for SSL-Ds to assist endoscopists in making immediate diagnoses, thus improving the quality of endoscopic examination and treatment.

Current progress on the endoscopic features of colorectal sessile serrated lesions.

Along with the discovery and refinement of serrated pathways, the World Health Organization amended the classification of digestive system tumors in 2019, recommending the renaming of sessile serrated adenomas/polyps to sessile serrated lesions (SSLs). Given the particularity of the endoscopic appearance of SSLs, it could easily be overlooked and missed in colonoscopy screening, which is crucial for the occurrence of interval colorectal cancer. Existing literature has found that adequate bowel preparation, reasonable withdrawal time, and awareness of colorectal SSLs have improved the quality and accuracy of detection.

Simultaneous removal of nitrogen and dimethyl phthalate from low-carbon wastewaters by using intermittently-aerated constructed wetlands.

Phthalic acid esters (PAEs) such as dimethyl phthalate (DMP) have been widely used as a plasticizer in society, which pose severe harm to human health. In this study, the potential of DMP elimination and nitrogen removal from low-carbon wastewaters by intermittently-aerated subsurface flow constructed wetlands (SSFCWs) was evaluated, and the effect of the influent DMP concentrations on nitrogen removal was also investigated. The results showed a better removal of DMP (88.

Differences in cadmium absorption by 71 leaf vegetable varieties from different families and genera and their health risk assessment.

Leaf vegetables have strong capabilities to take up cadmium (Cd) compared to other vegetable varieties. Until now, the differences in Cd uptake and accumulation by leaf vegetables from different families and genera and the related health risks were unknown. To remedy this, we studied 71 leaf vegetables (multiple genotypes within 17 categories of vegetables) in soil cultivation experiments (3 Cd treatment levels).

Elevated atmospheric CO might increase the health risk of long-term ingestion of leafy vegetables cultivated in residual DDT polluted soil.

Residual dichlorodiphenyltrichloroethane (DDT) in the environment and a continuously increasing atmospheric carbon dioxide (CO) concentration are two issues that have received a lot of attention. This study was conducted using a pot experiment to investigate the interactive effects of elevated CO and DDT on the uptake of DDT, the physiological responses and the resulting health risks in three vegetables. These vegetables included Brassica juncea var.

Ion flux profiles and plant ion homeostasis control under salt stress.

The ability of a plant to maintain an ionic homeostasis is crucial in plant salt tolerance. Direct evidence based on data from the non-invasive measurement of ion fluxes would not only offer new insight about the function of the transporter but also provide a whole plant approach for dissecting salt adaptation mechanisms. Here, we review some reports using the ion-selective microelectrodes to characterize the net ion fluxes of tissues or cells.

Identification of drought tolerance determinants by genetic analysis of root response to drought stress and abscisic Acid.

Drought stress is a common adverse environmental condition that seriously affects crop productivity worldwide. Due to the complexity of drought as a stress signal, deciphering drought tolerance mechanisms has remained a major challenge to plant biologists. To develop new approaches to study plant drought tolerance, we searched for phenotypes conferred by drought stress and identified the inhibition of lateral root development by drought stress as an adaptive response to the stress.
