Staphylococcus aureus belongs to one of the most common bacteria causing healthcare and community associated infections in China, but their molecular characterization has not been well studied. From May 2011 to June 2012, a total of 322 non-duplicate S. aureus isolates were consecutively collected from seven tertiary care hospitals in seven cities with(More)
BACKGROUND Dynamic contrast-enhanced MRI (DCE-MRI) estimates vascular permeability of brain tumors, and susceptibility-weighted imaging (SWI) may demonstrate tumor vascularity by intratumoral susceptibility signals (ITSS). This study assessed volume transfer constant (Ktrans) accuracy, the volume of extravascular extracellular space (EES) per unit volume of(More)
Autologous bone grafts (ABGs) are considered as the gold standard for spinal fusion. However, osteoporotic patients are poor candidates for ABGs due to limited osteogenic stem cell numbers and function of the bone microenvironment. There is a need for stem cell-based spinal fusion of proven efficacy under either osteoporotic or nonosteoporotic conditions.(More)
Cloud computing has changed how services are provided and supported through the computing infrastructure. However, recent work [11] reveals that virtual machine (VM) colocation based side-channel attack can leak users' privacy. Techniques have been developed against side-channel attacks. Some of them like NoHype remove the hypervisor layer, which suggests(More)
BACKGROUND Systematic reviews (SRs) of TCM have become increasingly popular in China and have been published in large numbers. This review provides the first examination of epidemiological characteristics of these SRs as well as compliance with the PRISMA and AMSTAR guidelines. OBJECTIVES To examine epidemiological and reporting characteristics as well as(More)
Android multitasking provides rich features to enhance user experience and offers great flexibility for app developers to promote app personalization. However, the security implication of Android multitasking remains under-investigated. With a systematic study of the complex tasks dynamics, we find design flaws of Android multitasking which make all recent(More)
BACKGROUND Many studies have shown that ghrelin can down-regulate inflammatory cytokine expression via the inhibition of NF-κB activity and therefore, its administration to septic patients is considered beneficial. However, our knowledge of ghrelin's effects on the upstream activators of the NF-κB pathway, such as NOD2, is still limited. This study aimed to(More)
To determine whether myo-inositol supplement will increase the action of endogenous insulin, which is mainly measured by markers of insulin resistance such as homeostasis model assessment of insulin resistance.PubMed, Cochrane Library, Embase, and web of science were comprehensively searched using "gestational diabetes mellitus" and "myo-inositol" to(More)
A membrane bioreactor (MBR) was adopted for completely autotrophic nitrogen removal over nitrite (CANON) process at ambient temperature. CANON was rapidly started-up within around 50d under oxygen-limited condition. The average nitrogen removal rate reached to 0.70kgNm(-3)d(-1) with a removal efficiency of 88%. The ratio of air flow rate to volumetric(More)
Osteoporosis is a progressive bone disease due to low osteoblast activity and/or high osteoclast activity. NELL-1 is a potential therapy for osteoporosis because it specifically increases osteoblast differentiation. However, similar to other protein drugs, the bioavailability of NELL-1 may be limited by its in vivo half-life and rapid clearance from body.(More)
