[Impact of Phosphogypsum Wastes on the Wheat Growth and CO2 Emissions and Evaluation of Economic-environmental Benefit].

Phosphogypsum is a phosphorus chemical waste which has not been managed and reused well, resultantly, causing environmental pollution and land-occupation. Phosphogypsum wastes were used as a soil amendment to assess the effect on wheat growth, yield and CO2 emissions from winter wheat fields. Its economic and environmental benefits were analyzed at the same time.

Evidence for anaerobic ammonium oxidation process in freshwater sediments of aquaculture ponds.

The anaerobic ammonium oxidation (anammox) process, which can simultaneously remove ammonium and nitrite, both toxic to aquatic animals, can be very important to the aquaculture industry. Here, the presence and activity of anammox bacteria in the sediments of four different freshwater aquaculture ponds were investigated by using Illumina-based 16S rRNA gene sequencing, quantitative PCR assays and (15)N stable isotope measurements. Different genera of anammox bacteria were detected in the examined pond sediments, including Candidatus Brocadia, Candidatus Kuenenia and Candidatus Anammoxoglobus, with Candidatus Brocadia being the dominant anammox genus.

Survival and differentiation of neuroepithelial stem cells following transplantation into the lateral ventricle of rats.

Neuroepithelial stem cells (NEPs) demonstrate a high potential for self-renewal and differentiation during embryonic development. To explore the survival and differentiation of NEPs in vivo, we isolated NEPs from green fluorescence protein (GFP) transgenic embryos and transplanted into the lateral ventricle of rats. In vitro culture, NEPs proliferated into neurospheres and differentiated into both neurons and glia.

[Experimental studies of human adipose tissue-derived stromal cells transfected with ad-hBMP-2 gene].

Objective: To investigate the possibility of adipose-derived stromal cells (ADSCs) transfeced by adenovirus containing human bone morphogenetic protein-2 (Ad-hBMP-2) gene and their osteogenic potential.

Methods: ADSCs were obtained from inguinal fat tissue of 4 weeks old SD rats. After exposure to adenovirus containing green fluorescent protein(Ad-GFP), fluorescent microscope was used to observe gene transfection effect once 12 hours.

[Correlation between periodontal disease and coronary atherosclerotic heart disease].

Objective: To investigate the correlation between coronary atherosclerotic heart disease (CAD) and periodontal disease (PD).

Method: Forty-five patients with CAD (CAD group) and 40 patients without CAD (control group) were compared with their pathological changes of periodontal tissues and inflammatory markers [high sensitive C reactive protein (hsCRP), interleukin-1beta (IL-1beta), and tumor necrosis factor-alpha (TNF-alpha)].

Results: Univariate analysis showed that the prevalence of PD was 84.

[Electromyography study on complete bilateral cleft lip after reparation.].

Purpose: This study was undertaken to evaluate the motion effect of complete bilateral cleft lips objectively using electromyography.

Methods: 45 patients of complete bilateral cleft lips after operations several years which included 20 patients repaired using orbicularis oris muscle restoring functional method and 25 patients using straight line suture method were examined with electromyography (EMG) in prolabium, right and left lateral lips respectively. The most potential in every area of each patient at the maximal lip contraction position was measured and the values of two different method groups were subject to statistical analysis.
