Apomorphine-induced rotation was monitored for 30 min at various time points after grafting. The striata were cut and examined for dopamine content by HPLC and for immunohistochemical staining of tyrosine hydroxylase positive neurons (TH +) at the end of the experiments. The results showed that apomorphine-induced rotational behavior was significantly reduced for 12 weeks and the dopamine contents were significantly elevated after grafting (P<0.01), and TH + cells survived better. The present study demonstrates that intrastriatal heterograft of glomus cells within carotid body in rats with 6-OHDA-elicited lesions could reduce apomorphine-induced rotational behavior and elevate the dopamine contents and numbers of TH + cell surviving within striatum, and can serve as a new and effective alternative for Parkinson disease.展开更多
The Pd-B/g-Al2O3 amorphous alloy catalyst and Pd/g-Al2O3 crystalline metal catalyst were prepared by KBH4 reduction and routine impregnation, respectively.

Pd-B/g-Al2O3 and Pd/g-Al2O3 catalysts were characterized by XRD and SEM. It was found that the catalytic activity of the Pd-B/g-Al2O3 amorphous alloy catalyst was higher than that of the Pd/g-Al2O3 crystalline metal catalyst in the anthraquinone hydrogenation.展开更多

Taking the wellbore storage and steady-state skin effect into consideration, the exact solutions of the pressure distribution of fluids flow in fractal reservoirs with double porosity are given for the cases of an infinite outer boundary, a finite closed outer boundary and a bounded domain with the constant pressure outer boundary conditions. The pressure behavior of fractal reservoir with double porosity is analyzed by using a numerical inversion of the Laplace transform solution. The pressure responses of changing various parameters are discussed.展开更多

The callers included various age groups (aged 12-7 8), different marital status, from Shanghai and outside. In total, the numbers o f men and women on hotline calls were almost same. The contents of the hotline c ounseling covered all aspects of reproductive health care; among them, the issue concerning male and female sex problems and prenatal and infant health care con stituted 26.5% and 34% respectively. Men asked questions about sex more frequent ly than women, whereas women asked questions more about baby care. Questions a bout sex problems were asked more often in the late evening until next early mor ning. Conclusions: Shanghai people showed higher needs in sexual heal th care, prenatal care and baby care. When they came across some related problem s or confusions, they would like to receive the professional instant counseling. Relevant health care programmes should be established in order to meet the fer tile-aged public's reproductive health needs.展开更多

This paper presents the basic method that VTP uses to transmit real-time I/O message, explicit message and maintenance message in scheduled part, unscheduled part and guardband part respectively. On the basis of analyzing the factors of message transmission delay, the maximum message transmission delay in scheduled part is studied, and the result shows it can be determined, so the deterministic and repeatability of message transmission in ControlNet is validated.展开更多
