[Combined Remediation of Eutrophic Water by Phoslock and Aerobic Denitrifying Bacteria].

Nitrogen and phosphorus are the leading causes of water eutrophication, and it is challenging to remove nitrogen and phosphorus effectively through a single water remediation method. In this study, an aerobic denitrifying bacterium (AD-19) isolated from eutrophic water was used to construct an immobilized biofilm and combined with Phoslock to remove nitrogen and phosphorus from the water. The phosphorus control efficiency of Phoslock, nitrogen removal performance of the denitrifying bacteria, and combined remediation performance for the eutrophic water were studied.

Methods: This study is a prospective randomized trial involving 187 women with primary SUI; 77 received TVT, 65 received TVT-O, and 45 patients were treated with TVT-O between June 2002 and December 2009. Before the operation, a complete medical history was taken and a gynecologic examination was performed, including subjective symptoms, history and urodynamic studies.

Rapamycin regulates Akt and ERK phosphorylation through mTORC1 and mTORC2 signaling pathways.

Numerous studies have shown that mammalian target of rapamycin (mTOR) inhibitor activates Akt signaling pathway via a negative feedback loop while inhibiting mTORC1 signaling. In this report, we focused on studying the role of mTORC1 and mTORC2 in rapamycin-mediated Akt and ERK phosphorylation, and the antitumor effect of rapamycin in cancer cells in combination with Akt and ERK inhibitors. Moreover, we analyzed the effect of mTORC1 and mTORC2 on regulating cell cycle progression.
