The Sundt encircling clip was developed to repair defects of the vessel wall. With the advent of microvascular techniques, most parts of the damaged vessel wall during aneurysm surgery can be repaired by primary closure or by the bypass technique. However, these methods are not always successful. Here, we illustrate two cases of surgical clipping with the Sundt encircling clip in the ruptured i...

The first crystal structure of a ring helicase encircling single-stranded DNA reveals a mechanism for ATP-dependent DNA translocation.

We give a direct construction of the conformally invariant measure on self-avoiding loops in Riemann surfaces (Werner measure) from chordal SLE8/3. We give a new proof of uniqueness of the measure and use Schramm’s formula to construct a measure on boundary bubbles encircling an interior point. After establishing covariance properties for this bubble measure, we apply these properties to obtain...

BACKGROUND In an attempt to potentiate the effect of laparoscopic gastric banding (LGB) on weight reduction and to reduce the risk of weight regain, we added laparoscopic truncal vagotomy (TV) to adjustable LGB. We report on our early interim results of a prospective 5-year randomized clinical trial comparing patients who underwent LGB plus TV (LGBTV) with a control group who underwent LGB alon...

The efficacies of a 20% 1-methyl-propyl-2- (hydroxyethyl)-1-piperidinecarboxylate (picaridin) spray, 20% 3-(N-acetyl-N-butyl)aminopropionic acid ethyl ester (IR3535) spray, 20% picaridin lotion, 10% IR3535 lotion, and 33% N,N-diethyl-3-methylbenzamide (deet) cream in repelling nymphal lone star ticks, Amblyomma americanum (L.), were determined at 2-h intervals over 12 h using human subjects. A ...

We assess some recently advanced arguments for the claim that the RMB is undervalued. These arguments are those based on the direct valuation of the RMB, trade imbalances, the accumulation of foreign exchange reserves, and the degree of policy dependence. The extant evidence does not support a strong verdict regarding RMB undervaluation that meets the statistical standards of academic empirical...
