Sulfotransferase 1A1 (SULT1A1) is reported to be involved in the conjugation with sulfate, resulting in the inactivation of estrogens. Aberrant methylation of promoter CpG islands is known to be responsible for the alteration and silencing of the gene in cancers. This study was intended to evaluate the methylation status and transcriptional activity of SULT1A1 in breast cancer tissue (n=56), be...

We give an example of an operator that satisfies the curvature condition as defined in [2], but is not similar to the backward shift S ∗ on the Hardy class H. We conclude therefore that the contraction assumption in the similarity characterization given in [2] is a necessary requirement.

I am interested in solving system security problems via program analysis techniques. More speci€cally, I have developed fundamental primitives for the investigation of advanced cyber-aŠacks and the analysis and prevention of everevolving malicious programs and payloads across multiple platforms. In particular, my research focuses on building systems to solve three prominent problems in system s...

BACKGROUND Age-related declines in balance and walking ability are major risk factors for falls. Older adults reduce the dynamic components of walking in an effort to achieve a more stable walking pattern. Tae Kwon Do is an exercise that trains dynamic components of balance and walking that diminish with age. METHODS Twenty participants from a Tae Kwon Do exercise class (average age 72.7 year...

BACKGROUND Previous reviews of tae kwon do (TKD) tournaments have documented injury rates of 25/1000 to 12.7/100 athlete exposures. Most injuries have been reported to be to the head and the neck and are occasionally very serious. Many of these studies involved high level TKD competitions with minimal safety precautions. Recently, safety measures have been implemented in many TKD competitions. ...
