BACKGROUND MYST1 (also known as hMOF), a member of the MYST family of histone acetyltransferases (HATs) as an epigenetic mark of active genes, is mainly responsible for histone H4K16 acetylation in the cells. Recent studies have shown that the abnormal gene expression of hMOF is involved in certain primary cancers. Here we examined the involvement of hMOF(More)
We consider the problem of source number estimation in array processing when impulsive noise is present. To combat impulsive noise more effectively, two robust estimators with high breakdown points, i.e., the minimum covariance determinant (MCD) estimator and the MM-estimator are applied in combination with the bootstrap. The MCD estimator is applied to(More)
OBJECTIVE To perform a prospective randomized trial comparing the efficacy and safety of percutaneous nephrolithotomy (PCNL) in the prone and modified supine positions. METHODS Between August 2010 and August 2011, 102 patients with renal calculi and 20 patients with ureteral calculi were randomized to undergo fluoroscopy and ultrasound-guided PCNL(More)
Despite accumulating evidence suggesting a critical role of signal transducer and activator of transcription 3 (STAT3) and Survivin in human bladder cancer, the effects of silencing these genes on the proliferation of T24 bladder carcinoma cells remain unknown. Here, we investigated the inhibitory effects of STAT3 or Survivin silencing on the in vitro and(More)
The problem of source enumeration in array processing is investigated. In an information theoretic criterion framework, we use in addition to the probability density function of observations, the probability density function of the sample eigenvalues obtained from the sample covariance matrix of the observations. Although the latter adds information to the(More)
The sensitivity of biosensors is often not sufficient to detect diagnostically relevant biomarker concentrations. In this paper we have utilized a Quartz Crystal Microbalance with Dissipation monitoring (QCM-D) to detect dissipative losses induced by the attachment of intact vesicles. We modified a sandwich assay by coupling the secondary antibodies to(More)
We consider the problem of source enumeration in array processing when only few samples are available. In this case, the noise eigenvalues 1 spread, so that most existing methods , which assume equality of the noise eigenvalues implicitly , suffer large performance loss or even break down. We present a method based on hypothesis testing with the boot-strap.(More)
