At the most recent follow-up after anatomic repair, moderate AR developed in 1 patient, and moderate or more LV dysfunction developed in 4. LV dysfunction developed in 4 of 6 patients banded after 2 years of age, compared with 0 of 12 patients banded GW4869 Apoptosis inhibitor before 2 years (p = 0.005). After anatomic repair, LV dysfunction developed in 4 of 7 patients repaired after age 3 years compared with 0 of 11 repaired before 3 years (p = 0.01).\n\nConclusions. Early PAB strategy is associated with favorable LV and neoaortic valve

function after anatomic repair for ccTGA with an unprepared LV. Candidates for anatomic repair who require LV training should be referred early in infancy for consideration of appropriate timing of PAB. (C) 2013 by The Society of Thoracic Surgeons”
“Strigolactones were originally identified as stimulators of the germination of root-parasitic weeds(1) that pose a serious threat to resource-limited agriculture(2). They are mostly exuded from roots and function as signalling compounds in the initiation of arbuscular mycorrhizae(3), which are plant-fungus symbionts with a global effect on carbon and phosphate cycling(4). Recently, strigolactones

were established to be phytohormones that regulate plant shoot architecture by inhibiting the outgrowth of axillary buds(5,6). Despite their importance, it is not known how strigolactones are transported. ATP-binding cassette (ABC) transporters, however, are known to have functions in phytohormone translocation(7-9). Here we show that the Petunia hybrida ABC transporter PDR1 has a key role in regulating the development of arbuscular mycorrhizae and axillary branches, by LDK378 price functioning as a cellular strigolactone exporter. P. hybrida pdr1 mutants are defective in strigolactone exudation from their roots, resulting in reduced symbiotic interactions. Above ground, pdr1

mutants have an enhanced branching phenotype, which is indicative of impaired strigolactone allocation. Overexpression of Petunia axillaris PDR1 in Arabidopsis thaliana results in increased tolerance to high concentrations of a synthetic strigolactone, consistent with increased export of strigolactones from the roots. PDR1 is the first known component in strigolactone transport, providing new opportunities for investigating and manipulating strigolactone-dependent processes.”
“Sleep enhances integration across multiple stimuli, abstraction of general rules, insight into hidden solutions and false memory formation. Newly learned information is better assimilated if compatible with an existing cognitive framework or schema. This article proposes a mechanism by which the reactivation of newly learned memories during sleep could actively underpin both schema formation and the addition of new knowledge to existing schemata. Under this model, the overlapping replay of related memories selectively strengthens shared elements.
