\n\nMethods: All
perforator-supercharged occipitocervicopectoral flaps that were used for face and neck reconstructions were analyzed retrospectively.\n\nResults: In all nine cases, the second internal mammary artery perforator was attached at the end of the occipitocervicopectoral flap and supercharged with the contralateral recipient facial artery vessels. The average flap size was 22.6 x 6.2 cm, without selleck inhibitor any flap loss. It was possible to cover a large defect extending to bilateral sides with thin and pliable local skin tissue. All patients were satisfied with functional and aesthetic results achieved postoperatively after 6 months.\n\nConclusions: The internal click here mammary artery perforator-supercharged occipitocervicopectoral flap can be considered a type of 4 bipedicle perforator flap and can provide reliable flap vascularity. By using a perforator supercharging technique, we can adjust and enlarge the flap length tailored to the defect. (Plast. Reconstr.

“Plants are unique in their ability to continuously produce new meristems and organ primordia.
In Arabidopsis, the transcription factor LEAFY (LFY) functions as a master regulator of a gene network that is important for floral meristem and organ specification. UNUSUAL FLORAL ORGANS (UFO) is a co-activator of LEAFY and is required for proper activation of APETALA3 in the floral meristem during the specification of stamens and petals. The ufo mutants display defects in other parts of the flower and the inflorescence, suggestive of additional roles. Here we show that the normal determinacy of the developing Arabidopsis leaves is affected by the expression of a gain-of-function UFO Selleck Vactosertib fusion protein with the VP16 transcriptional activator domain. In these lines, the rosette and cauline leaf
primordia exhibit reiterated serration, and upon flowering produce ectopic meristems that develop into flowers, bract leaves and inflorescences. These striking phenotypes reveal that developing leaves maintain the competency to initiate flower and inflorescence programs. Furthermore, the gain-of-function phenotypes are dependent on LFY and the SEPALLATA (SEP) MADS-box transcription factors, indicative of their functional interactions with UFO. The findings of this study also suggest that UFO promotes the establishment of the lateral meristems and primordia in the peripheral zone of the apical and floral meristems by enhancing the activity of LFY. These novel phenotypes along with the mutant phenotypes of UFO orthologs in other plant species suggest a broader function for UFO in plants.”
