To test the hypothesis that gut-derived factors carried in trauma-hemorrhagic shock (T/HS) lymph is sufficient to induce lung injury. Additionally, because our previous studies showed that T/HS-induced nitric oxide production was associated with lung injury, we examined whether T/HS lymph-induced lung injury occurs via an inducible nitric oxide synthase (iNOS)-dependent pathway. ⋯ These results indicate that T/HS lymph is sufficient to induce acute lung injury and that lymph-induced lung injury occurs via an iNOS-dependent pathway.

Randomized Controlled Trial Multicenter Study
The TME trial after a median follow-up of 6 years: increased local control but no survival benefit in irradiated patients with resectable rectal carcinoma.
To investigate the efficacy of preoperative short-term radiotherapy in patients with mobile rectal cancer undergoing total mesorectal excision (TME) surgery. ⋯ With increasing follow-up, there is a persisting overall effect of preoperative short-term radiotherapy on local control in patients with clinically resectable rectal cancer. However, there is no effect on overall survival. Since survival is mainly determined by distant metastases, efforts should be directed towards preventing systemic disease.

Randomized Controlled Trial
Hand-assisted laparoscopic versus open right colectomy: a randomized controlled trial.
Laparoscopic colectomy has been proved to be both technically and oncologically feasible. However, the approach has been criticized for its procedural complexity and long operative time as a result of the loss of tactile feedback and absence of depth perception. The advent of hand-access devices offered a potential solution to these problems. This randomized controlled trial aims to compare hand-assisted laparoscopic colectomy (HALC) with open colectomy (OC) in the management of right-sided colonic cancer. ⋯ HALC retained the same short-term benefits of the pure laparoscopic approach. The technique is associated with a slightly increased but acceptable operative time. Aside as a useful adjunct in complex laparoscopic procedures, the hand-assisted laparoscopic technique is also a useful, if not more effective, alternative for patients with right-sided colonic cancer.

We examined the transcriptional response to serum stimulation as an in vitro model of wound healing in keloid fibroblasts to identify molecular mechanisms leading to their aberrant growth. ⋯ We suggest that altered responsiveness to cellular stress, based upon current data using serum stimulation and past data on response to mechanical strain, is a key defect leading to keloid formation.
