Recently, more and more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content's confidentiality. All previous methods embed data by reversibly vacating room from the encrypted(More)
Due to the existence of security threats in the cloud, many mechanisms have been proposed to allow a user to audit data integrity with the public key of the data owner before utilizing cloud data. The correctness of choosing the right public key in previous mechanisms depends on the security of Public Key Infrastructure (PKI) and certificates. Although(More)
Saxitoxin (STX) and tetrodotoxin (TTX) are frequently used to selectively block sodium channels. In this study, we provide evidence that commercial STX also inhibits L-type Ca2+ currents (I(Ca,L)) in adult mouse ventricular myocytes (VMs) and tsA-201 cells that were transiently cotransfected with three calcium channel subunits. We measured inhibition of(More)
FK506 binding proteins (FKBPs 12 and 12.6) interact with ryanodine receptor (RyR) and modulate its functions. FK506 binds to and reverses effects of FKBP on RyR, thus increasing RyR sensitivity to Ca , decreasing RyR cooperativity, and increasing RyR open probability. FK506 would thus be expected to have an effect on excitation-contraction coupling, but(More)
A facile method to obtain polydisperse chemically-converted graphene sheets that are covalently functionalized with ionic liquid was reported -- the resulting graphene sheets, without any assistance from polymeric or surfactant stabilizers, can be stably dispersed in water, DMF, and DMSO.
Cloud computing enables customers with limited computational resources an economically promising paradigm of computation outsourcing. However, how to protect customers’ confidential data that is processed and generated during the computation is becoming a major security concern. To mitigate this problem, in this paper, we present a secure outsourcing(More)
Background—The Na-Ca exchanger (NCX) may contribute to Ca overload and injury in ischemic cardiomyocytes. Recently, NCX overexpression was reported to increase ischemia/reperfusion injury in male and oophorectomized female but not in female mice. We therefore measured the effects of gender and estrogen on [Ca]i and [Na ]i during metabolic inhibition (MI) in(More)
OBJECTIVES This study aimed at detecting whether Virtual Touch Tissue Quantification (VTQ) could be applied to differentiate between benign and malignant thyroid nodules with chronic autoimmune Hashimoto's thyroiditis (HT). METHODS Convenient ultrasound and Virtual Touch Tissue Quantification were performed in 118 patients with 140 thyroid nodules with(More)
The aim of this study is to determine the diagnostic accuracy of contrast-enhanced ultrasonography (CEUS) for diagnosis of small (≤2 cm in diameter) hepatocellular carcinoma (HCC) through a meta-analysis of published studies. A comprehensive literature search of PubMed, Embase, Web of Science, and China BioMedicine databases was conducted on articles(More)
