BACKGROUND The challenge with the surgical repair of upper eyelid retraction is to obtain a more predictable and satisfactory postoperative eyelid contour and height, and to minimise the need for further surgery. METHODS A retrospective analysis was performed on all patients treated surgically for eyelid retraction at Moorfields Eye Hospital over a 13 year period. RESULTS In this study good...

In this paper, we propose a vector transport-free stochastic variance reduced gradient (SVRG) method with general retraction for empirical risk minimization over Riemannian manifold. Existing SVRG methods on manifold usually consider a specific retraction operation, and involve additional computational costs such as parallel transport or vector transport. The vector transport-free SVRG with gen...

The effects of rifampin and streptolydigin, inhibitors of ribonucleic acid (RNA) synthesis, on the production of F pili by Escherichia coli were studied by electron microscopy. The inhibition of RNA synthesis reduces the number of new pili produced by depiliated cells, but does not affect their length or the number of pili present at the time of inhibition or the retraction of pili. We suggest ...

BACKGROUND Differing levels of tendon retraction are found in full-thickness rotator cuff tears. The pathophysiology of tendon degeneration and retraction is unclear. Neoangiogenesis in tendon parenchyma indicates degeneration. Hypoxia inducible factor 1α (HIF) and vascular endothelial growth factor (VEGF) are important inducers of neoangiogenesis. Rotator cuff tendons rupture leads to fatty mu...

BACkgROUnD: no randomized controlled trial has tried to compare treatment outcomes between the sliding en-masse retraction of upper anterior teeth supported by mini-implants and the two-step sliding retraction technique employing conventional anchorage devices. OBjECTIvE: To evaluate skeletal, dental, and soft tissue changes following anterior teeth retraction. DESIgn AnD SETTIng: Parallel-grou...
