Effect of co-application of straw and various nitrogen fertilizers on NO emission in acid soil.

In order to explore the alteration of N transformation and NO emissions in acid soil with the co-application of straw and different types of nitrogen (N) fertilizers, an incubation experiment was carried out for 40 days. There are totally five treatments in the study: (a) without straw and N fertilizer (N0), (b) straw alone application (SN0), (c) straw with NHCl (SN1), (d) straw with NaNO (SN2), and (e) straw with NHNO (SN3). NO emissions, soil physicochemical properties, and abundance/activity of ammonia-oxidizing archaea (AOA) were measured.

Can the co-application of biochar and different inorganic nitrogen fertilizers repress NO emissions in acidic soil?

The sole application of nitrogen (N) fertilizer with lower NO emission potential or combined with biochar may help for mitigating NO production. However, how biochar applied with various inorganic N fertilizers affected NO emission in acidic soil remains unclear. Thus, we examined NO emission, soil N dynamics and relating nitrifiers (i.

[Analysis of Proliferation Characters of Bone Marrow Mesenchymal Stem Cells Derived from Patients with Myelodysplastic Syndrome].

Objective: To analyze the proliferation potential of bone marrow-derived mesenchymal stem cells (MSC) in patients with myelodysplastic syndrome (MDS).

Methods: The MSC derived from the 24 patients with newly diagnosed MDS (MDS-MSC group) and MSC derived from 15 patients with nutritional anemia (control group) in the Affiliated Hospital of Hebei University were used as the research objects. The proliferation potential of MSC was analyzed by colony-forming unit assay, doubling time, cumulative passaging, cell number after 10 days of culture with equal amount of MSC and MTT experiment.

[Spinal cord magnetic resonance imaging: methods and applications].

Spinal cord magnetic resonance imaging (MRI) is an advanced imaging technique (mainly in the cervical cord) and has been gradually used in basic scientific research such as human sensation and motor function, and clinical applications such as spinal cord injury, myelitis, and chronic pain, etc. The development of spinal cord MRI is still at the early stage compared with brain MRI and limited by the current MRI technology and data analysis methods. This review focuses on the methods and applications of spinal cord MRI technology in the basic research fields of cognitive neuroscience and clinical application.

Effect of floral cluster pruning on anthocyanin levels and anthocyanain-related gene expression in 'Houman' grape.

Lateral floral clusters were removed from the main axis of the floral clusters of 'Houman' grape plants, leaving only 3-5-cm-long region of flowers at the end of the central axis. The floral clusters were pruned at 7 days prior to flowering. The effect of the pruning on fruit quality was assessed by determining the composition and levels of anthocyanins in the fruit and anthocyanin-related gene expression.

A subject-specific pelvic bone model and its application to cemented acetabular replacements.

A subject-specific three-dimensional finite element (FE) pelvic bone model has been developed and applied to the study of bone-cement interfacial response in cemented acetabular replacements. The pelvic bone model was developed from CT scan images of a cadaveric pelvis and validated against the experiment data obtained from the same specimen at a simulated single-legged stance. The model was then implanted with a cemented acetabular cup at selected positions to simulate some typical implant conditions due to the misplacement of the cup as well as a standard cup condition.
