BACKGROUND Plantar hindpaw incision produces hyperalgesia, transient upregulation of cyclooxygenase-2 (COX-2) and prolonged upregulation of cyclooxygenase-1 (COX-1) in rat lumbar spinal cord. Our hypothesis in this study was that a deep thoracic incision causes COX-1 and COX-2 upregulation in the dorsal horn coincident with pain-related behavior, and that specific cell types contribute to this ...

OBJECTIVE To evaluate the influence of either incision on the lungs and chest wall. METHODS Ninety-two double lung (DLT) or heart-lung (HLT) transplantations were done since January 1990. There were 22 (24%) hospital deaths, leaving 70 patients with complete data for evaluation. We did 38 DLT and 32 HLT for end-stage chronic respiratory failure (n = 22) and primary (n = 34) or secondary (n = ...

We investigated the effect of incision and sternotomy on the auditory evoked potential (AEP) and EEG, to try to predict a haemodynamic response to incision or sternotomy using the AEP and EEG in 41 patients undergoing cardiac surgery during propofol and alfentanil anaesthesia. The AEP and EEG were recorded before incision, between incision and sternotomy, and after sternotomy. Peak latencies an...

BACKGROUND To evaluate the effectiveness of minimally invasive surgery total hip arthroplasty (THA) using the two-incision technique as described by Mears. METHODS From January 2003 to December 2006, sixty-four patients underwent total hip arthroplasty using the one-incision (group I) and two-incision (group II) technique by one surgeon. There were 34 hips in group I and 30 hips in group II. ...

BACKGROUND Mechanisms underlying postoperative pain remain poorly understood. In rodents, skin-only incisions induce mechanical and heat hypersensitivity similar to levels observed with skin plus deep incisions. Therefore, cutaneous injury might drive the majority of postoperative pain. TRPA1 and TRPV1 channels are known to mediate inflammatory and nerve injury pain, making them key targets for...

The term ‘‘incision wave’’ was coined in the 1990s to describe wave-like patterns of stream incision propagating through numerically modeled bedrock-channel river systems. An incision wave consists of a crest where available stream power is greatest, and where vertical incision is most rapid. The crest is flanked by limbs where there is less available stream power and where vertical incision ra...
