We have used homologous Red/ET recombination in Escherichia

coli to introduce wild-type and specifically mutated Uc-DR1-Ub fragments into an ectopic site of a cloned HSV-1 genome from which the resident packaging signals had been previously deleted. The resulting constructs were transfected into mammalian cells, and their abilities to replicate and become encapsidated, generate Uc- and Ub-containing terminal fragments, and give rise to progeny virus were assessed. In general, the results obtained agree well with previous observations made using amplicons and confirm roles for the pac2 T element in the initiation of DNA packaging and for the GC-rich motifs flanking the pac1 T element KU-60019 manufacturer in termination. In contrast to a previous report, the sequence of the DR1 element was also crucial for DNA packaging. Following repair of the resident packaging signals in mammalian cells, recombination occurred at high frequency in progeny virus between the repaired sequences and mutated Uc-DR1-Ub inserts. This restored the ability

of mutated Uc-DR1-Ub inserts to generate terminal fragments, although these were frequently larger than expected from simple repair of the original lesion.”
“Objective: To identify neurocognitive measures that could be used as objective markers of bipolar disorder.

Methods: We examined executive function, sustained attention Selleck Alvespimycin and short-term memory as neurocognitive domains in 18 participants with bipolar disorder in euthymic state (Beuth), 14 in depressed state (Bdep), 20 with unipolar depression (Udep) and 28 healthy control participants (HC). We conducted four-group comparisons followed by relevant post hoc analyses.

Results: Udep and Bdep, but not Beuth

showed impaired executive function (p=0.045 and p=0.046, respectively). Both Bdep and Beuth, but not Udep, showed impaired sustained attention (p=0.001 and p=0.045, respectively). The four groups did not differ significantly on short-term memory. Impaired sustained attention and methylhexanamine executive dysfunction were not associated with depression severity, duration of illness and age of illness onset. Only a small number of abnormal neurocognitive measures were associated with medication in Bdep and Beuth.

Conclusion: Impaired sustained attention appears specific to bipolar disorder and present in both Beuth and Bdep; it may represent an objective marker of bipolar disorder. Executive dysfunction by contrast, appears to be present in Udep and Bdep and likely represents a marker of depression. (C) 2010 Elsevier Ltd. All rights reserved.”
