Current treatment options include surgical interventions that enlarge the bladder with autologous bowel tissue to alleviate pressure on the upper urinary tract. This highly invasive procedure, termed bladder augmentation enterocystoplasty (BAE), significantly increases the risk of patient morbidity and mortality due to the incompatibility between bowel and bladder tissue. Therefore, patients would significantly benefit from an alternative treatment strategy that can regenerate healthy tissue and restore overall bladder function. Previous research has demonstrated the potential of citrate-based scaffolds co-seeded with bone marrow-derived stem/progenitor cells as an alternative graft for bladder augmentation. Recognizing that contact guidance can potentially influence tissue regeneration, we hypothesized that microtopographically patterned scaffolds would modulate cell responses and improve overall quality of the regenerated bladder tissue. We fabricated microgrooved (MG) scaffolds using the citrate-based biomaterial poly (1,8-octamethylene-citrate-co-octanol) (POCO) and co-seeded them with human bone marrow-derived mesenchymal stromal cells (MSCs) and CD34+ hematopoietic stem/progenitor cells (HSPCs). MG POCO scaffolds supported MSC and HSPC attachment, and MSC alignment within the microgrooves. All scaffolds were characterized and assessed for bladder tissue regeneration in an established nude rat bladder augmentation model. In all cases, normal physiological function was maintained post-augmentation, even without the presence of stem/progenitor cells. Urodynamic testing at 4-weeks post-augmentation for all experimental groups demonstrated that bladder capacity increased and bladder compliance was normal. Histological evaluation of the regenerated tissue revealed that cell-seeded scaffolds restored normal bladder smooth muscle content and resulted in increased revascularization and peripheral nerve regeneration. The presence of microgrooves on the cell-seeded scaffolds increased microvasculature formation by 20 % and urothelial layer thickness by 25 % in the regenerating tissue. Thus, this work demonstrates that microtopography engineering can influence bladder tissue regeneration to improve overall anatomical structure and re-establish bladder physiology.展开更多

However, as a company owner myself, I have to say that there is one noticeable upside to this global recession: it is a great time, as an employer, to be picking up and bringing on board top talent, and to do so at a reasonable cost. It's like discount shopping for branded goods.展开更多

While many multinationals are undergoing a corporate-wide headcount and hiring freeze, many Chinese companies are actively hiring. Most local companies have a domestic market focus that has been relatively little impacted by the global recession and do not carry the same highly leveraged debt as global corporations. This makes them a serious employment option for many foreigners and Chinese professionals with overseasexperience.展开更多

Actually, what he was trying to do was determine whether it is worth putting so much effort into his company in the current situation, or if it would end up being a waste of time. From my perspective, he was putting too much time and energy into this assessment as it had no bearing on his ability to pursue career success during this tough economic period.展开更多

The reason was simple. Overseas experience provided huge benefits to their career development.

The tougher times are forcing many to look more deeply at how they are assessing their employment choices and decisions. The main result is a maturing, longer-term approach to career development and success. Whether they realize it now or not, this approach will serve them well over the course of their career.展开更多
