BACKGROUND Microbubbles and contrast-enhanced ultrasound (CEUS) is a new technique for locating sentinel lymph node (SLN). The aim of this study is to explore the feasibility of SLNs tracing by CEUS using microbubbles in breast cancer patients and the value of enhancing patterns in diagnosing lymph nodes metastases. METHODS A clinical trial was registered(More)
Tissue engineering approaches have been successfully used in repairing bone defects and have become a viable alternative to autologous bone. The aim of the present study was to investigate if a construct of porous beta-tricalcium phosphate (β-TCP) combined with osteogenically induced bone marrow stromal cells (bMSCs) could repair alveolar cleft, and allow(More)
The effect of ozone on deoxynivalenol (DON) detoxification was investigated. Ozone treatment could significantly reduce the levels of DON in wheat; 53% of DON in wheat was decomposed with 90 mg l-1 of ozone at a flow rate of 15 l min-1 for 4 h. The safety of DON-contaminated wheats (DCWs) untreated/treated by ozone was also evaluated. Institute of Cancer(More)
A great challenge China's power sector faces is to mitigate its carbon dioxide emissions while satisfying the ever-increasing power demand. Optimal planning of the power sector with consideration of carbon mitigation for a long-term future remains a complex task, involving many technical alternatives and an infinite number of possible plants installations,(More)
o avoid the worst consequences of global warming, the world must limit average temperature increases to 2°C or less by reducing carbon emissions at least 50 percent below 1990 levels by the year 2050. 1 Since the publication of the IPCC's last synthesis report, several recent studies have further found that the committed warming as of today will exceed 2°C,(More)
In order to supply optimum water to restore reed wetlands used for bird habitats, a field investigation and greenhouse experiment were conducted. Three water supplementation stages (early stage at 20 May, middle stage at 20 July and later stage at 20 September, respectively) and five depths (0, 10, 15, 20 and 35 cm over the surface, respectively) were(More)
Inspired by the special asymmetric wettability and controllable permeating function of cell membrane, we reported a Janus nanostructured copper mesh film with unidirectional water transportation ability, on which, water can permeate from the hydrophobic side to the hydrophilic side, while it be retained from the opposite direction. Noticeably, based on the(More)
OBJECTIVE To evaluate the effects of casein osphopeptide-amorphous calcium phosphate (CPP-ACP) in preventing enamel demineralization. METHODS Enamel blocks were prepared from premolars extracted from orthodontic patients. The specimens were treated for 30 min daily for 7 days with one of the following agents: deionized water (negative control), CPP-ACP(More)
Carbon capture and sequestration (CCS) is an important option for CO 2 mitigation and an optimized CO 2 pipeline transport system is necessary for large scale CCS implementation. In the present work, a hydro-dynamic model for CO 2 pipeline transport was built up and the hydrodynamic performances of CO 2 pipeline as well as the impacts of multiple factors on(More)
