Recombinant Human Thyrotropin Plus Radioactive Iodine Among Patients With Thyroid Cancer: A Noninferiority Randomized Clinical Trial.

Importance: Radioactive iodine (131I or RAI) therapy has long been the standard of care for most patients with differentiated thyroid cancer (DTC) after primary surgery. However, no multicenter prospective studies have identified the optimal administered activity and stimulation method for RAI therapy in patients with intermediate-risk DTC.

Objective: To compare the efficacy and safety of recombinant human thyrotropin (SNA001) with thyroid hormone withdrawal (THW) plus 3.

Effects of LB broth, naphthalene concentration, and acetone on the naphthalene degradation activities by Pseudomonas putida G7.

Luria-Bertani broth and acetone were usually used in naphthalene degradation experiments as nutrient and solvent. However, their effect on the degradation was seldom mentioned. In this work, we investigated the effect of LB, naphthalene concentration, and acetone on the degradation of naphthalene by Pseudomonas putida G7, which is useful for the degradation of naphthalene on future field remediation.

Research and application of in-situ control technology for sediment rehabilitation in eutrophic water bodies.

Phosphorus (P) is often the limiting nutrient for algal growth, and P in sediments can be released under suitable conditions. To control P release, in-situ control technology with lanthanum (La) modified bentonite clay (Phoslock(®)) was proposed and its effectiveness was tested and evaluated both in laboratory and field trials. The results of static and dynamic simulation experiments under different environmental conditions showed that with the application rate of Phoslock(®) at 0.

[Study on the effect of total phosphor removing by constructed submerged hydrophyte bed for urban landscape river].

A kind of modularized and air adjustable constructed submerged plant bed (CSPB) was used to restore the eutrophic water. This CSPB helps hydrophytes to grow up under poor conditions, like frequently changed water depth, blurred water transparency, algae bloom and duckweed rampant in summer, which are not suitable for growing water plants naturally. The experiments in Waihuan River of Tianjin show that total phosphor (TP) reduces 30%-40% in growing season and 7%-20% in winter when the detention time is 5.

[Effect of intermittent artificial aeration on nitrogen and phosphorus removal in subsurface vertical-flow constructed wetlands].

Shale and T. latifolia were used as subsurface vertical-flow constructed wetland substrate and vegetation for eutrophic Jin River water treatment, and investigate the effect of intermittent aeration on nitrogen and phosphorus removal. In this study, hydraulic loading rate was equal to 800 mm/d, and ratio of air and water was 5:1.

[Optimization of nitrogen and phosphorus removal in vertical subsurface flow constructed wetlands by using polypropylene pellet as part of substrate].

Constructed wetlands experiments were conducted by using shale and Typha latifolia L. as vertical subsurface flow constructed wetland substrate and plant for eutrophic Jin River water treatment, and part of shale with polypropylene pellet was replaced to investigate its effect on nitrogen and phosphorus removal. In this study, hydraulic loading rate was equal to 800 mm/d, theoretic residence time was equal to 12 h.
