Vascularization of tissue-engineered bones is critical to achieving satisfactory repair of bone defects. The authors investigated the use of prevascularized tissue-engineered bone for repairing bone defects. The new bone was greater in the prevascularized group than in the non-vascularized group, indicating that prevascularized tissue-engineered bone improves the repair of bone defects. [Orthop...

The notion of strict closedness rings was given by J. Lipman [Amer. Math. 93 (1971), pp. 649–685] in connection with a conjecture O. Zariski. present purpose is to give practical method construction strictly closed rings. It also shown that the Stanley-Reisner simplicial complexes (resp. $F$-pure satisfying condition $(\operatorname {S}_2)$ Serre) are weakly Arf)

685 abscess. The kidney was not involved by the malignant process. Histology later revealed that the uterine mass was a mixed mesodermal sarcoma with a pattern of fibrosarcoma, chondrosarcoma, and in places osteogenic sarcoma. Review of the segment of colon removed at operation showed that this was in fact invaded from without by secondaries from the primary uterine tumour.

Bridge Over the Theory Practice Gap Introduction The gap between theory and practice has long been identified as a problem in nursing and midwifery. In the past this has been described as an " embarrassing failure " (Rafferty et al., 1996 p.685) and presently there is a strong consensus that the existence of this gap is not only pressing but increasing (Spouse 2001; Landers 2000).
