BACKGROUND Current teaching suggests increased perfusion in free transverse rectus abdominis myocutaneous (TRAM) flaps over pedicled TRAM flaps, broadening indications for its use in high risk patients. This study compared perfusion analysis of free muscle-sparing versus pedicle TRAM flaps in vivo in the peri-operative and late post-operative periods. METHODS The SPY-Elite system using...

abstract background: the transverse rectus abdominis musculocutaneous (tram) flap remains the gold standard for postmastectomy reconstruction either immediate or delayed. however, transfer of tram flap can be associated with donor site morbidities and complications in flap. a successful reconstruction consists of careful patient selection, surgical technique and meticulous preoperative planning...

TRIF-related adaptor molecule (TRAM) is the fourth Toll/IL-1 resistance domain-containing adaptor to be described that participates in Toll-like receptor (TLR) signaling. TRAM functions exclusively in the TLR4 pathway. Here we show by confocal microscopy that TRAM is localized in the plasma membrane and the Golgi apparatus, where it colocalizes with TLR4. Membrane localization of TRAM is the re...

TLRs act as sentinels in professional immune cells to detect and initiate the innate immune response to pathogen challenge. TLR4 is a widely expressed TLR, responsible for initiating potent immune responses to LPS. TRAM acts to bridge TLR4 with TRIF, orchestrating the inflammatory response to pathogen challenge. We have identified a putative TRAF6-binding motif in TRAM that could mediate a nove...

The effect of TraY protein on TraI-catalyzed strand scission at the R1 transfer origin (oriT) in vivo was investigated. As expected, the cleavage reaction was not detected in Escherichia coli cells expressing tral and the integration host factor (IHF) in the absence of other transfer proteins. The TraM dependence of strand scission was found to be inversely correlated with the presence of TraY....

Lipopolysaccharide (LPS)-induced production of tumor necrosis factor (TNF)-α requires the recruitment of two pairs of adaptors to the Toll-like receptor 4 cytoplasmic domain. The contribution of one pair - Toll-interleukin-1 receptor domain-containing adaptor inducing interferon-β (TRIF) and TRIF-related adaptor molecule (TRAM) - to TNF-α expression is not well understood. To clarify this issue...

BACKGROUND Our objective was to compare the complication rates of two common breast reconstruction techniques performed at our hospital and the cost-effectiveness for each test group. METHODS All patients who underwent deep inferior epigastric perforator (DIEP) flap and transverse rectus abdominis myocutaneous (TRAM) flap by the same surgeon were selected and matched according to age and mast...

Perforator flap breast reconstruction potentially offers patients greater postoperative abdominal strength compared with traditional TRAM techniques. Our purpose was to perform a systemic review of the published literature regarding abdominal wall function following breast reconstruction and compare outcomes between pedicle TRAM, free TRAM, and perforator flap procedures. We used the MEDLINE, E...
