Water Sci Technol 2021 Jun;83(11):2597-2614

Nanjing Research Institute of Environmental Protection, Nanjing Environmental Protection Bureau, Nanjing, Jiangsu 210013, China.

Membrane bioreactor (MBR) technology has been paid extensive attention for wastewater treatment because of its advantages of high effluent quality and minimized occupation space and sludge production. However, the membrane fouling is always an inevitable problem, which causes high operation and maintenance costs and prevents the wide use of MBR technology. The membrane biofouling is the most complicated and has relatively slow progress among all types of fouling. Read More

J Gastrointest Surg 2021 Jun 9. Epub 2021 Jun 9.

Department of Gastrointestinal Surgery, Renmin Hospital of Wuhan University, Wuhan, Hubei, 430060, People's Republic of China.

Background: Intraoperative damage of pelvic autonomic nerves is the primary reason for postoperative sexual and urinary dysfunction after rectal cancer surgery,1,2 especially in patients with low rectal cancer. In the present study, we developed the nerve plane as a novel concept in rectal cancer surgery, which served as a landmark for better preservation of pelvic autonomic nerves in standardized total mesorectal excision (TME) surgery. The nerves never exist alone, and are always surrounded by tiny capillaries and adipose tissue, which are covered by a thin layer of membranous tissue, leading to a continuous plane, which we defined as the nerve plane.
