Two-stage continuous cultivation of microalgae overexpressing cytochrome P450 improves nitrogen and antibiotics removal from livestock and poultry wastewater.

Improper treatment of livestock and poultry wastewater (LPWW) rich in ammonium nitrogen (NH-N) and antibiotics leads to eutrophication, and contributes to the risk of creating drug-resistant pathogens. The design-build-test-learn strategy was used to engineer a continuous process using Chlorella vulgaris to remove NH-N and antibiotics. The optimized system removed NH-N at a rate of 306 mg/L/d, degraded 99 % of lincomycin, and reduced the hydraulic retention time to 4 days.

NEDD4's effect on osteoblastogenesis potential of bone mesenchymal stem cells in rats concerned with PI3K/Akt pathway.

Neural precursor cell expressed developmentally down-regulated 4 (NEDD4) is an E3 ubiquitin ligase implicated in craniofacial development. Emerging evidence suggests that NEDD4 may down-regulates Akt signaling, a key element of the PI3K/Akt pathway involved in cell differentiation. This study aimed to investigate NEDD4's role in bone mesenchymal stem cells (BMSCs) differentiation and its interaction with the PI3K/Akt pathway.
