Longitudinal validity of the hemophilia caregiver impact measure

IntroductionThe hemophilia caregiver impact (HCI) measure is a 36-item self-report tool that has documented reliability and validity in a large cross-sectional study, but its longitudinal construct validity is unknown. This study’s objective was to evaluate the responsiveness of the HCI to clinically important change, and to provide interpretation guidelines.MethodsThis web-based...

Application of tabu search-based Bayesian networks in exploring related factors of liver cirrhosis complicated with hepatic encephalopathy and disease identification

This study aimed to explore the related factors and strengths of hepatic cirrhosis complicated with hepatic encephalopathy (HE) by multivariate logistic regression analysis and tabu search-based Bayesian networks (BNs), and to deduce the probability of HE in patients with cirrhosis under different conditions through BN reasoning. Multivariate logistic regression analysis...

A security scheme for intelligent substation communications considering real-time performance

Tampering, forgery and theft of the measurement and control messages in a smart grid could cause one breakdown in the power system. However, no security measures are employed for communications in intelligent substations. Communication services in an intelligent substation have high demands for real-time performance, which must be considered when deploying security measures. This...

Qualitative transcriptional signatures for evaluating the maturity degree of pluripotent stem cell-derived cardiomyocytes

BackgroundPluripotent stem cell-derived cardiomyocytes (PSC-CMs) are widely used models for regenerative medicine and disease research. However, PSC-CMs are usually immature in morphology and functionality and the maturity of PSC-CMs could not be determined accurately. In order to reasonably interpret the experimental results obtained by PSC-CMs, it is necessary to evaluate the...

Comparative effectiveness and safety of tranexamic acid plus diluted epinephrine to control blood loss during total hip arthroplasty: a meta-analysis

The standard protocol to achieve haemostasis during total hip arthroplasty (THA) is uncertain. Tranexamic acid plus diluted epinephrine (DEP) and tranexamic acid (TXA) alone are the two most common alternatives. The purpose of this study was to compare the efficacy and safety of TXA plus DEP to treat blood loss in THA patients. Published randomized controlled trials (RCTs) were...

Is preterm birth associated with asthma among children from birth to 17 years old? -A study based on 2011-2012 US National Survey of Children’s Health

Preterm birth can interrupt lung development in utero and is associated with early life factors, which adversely affects the developing respiratory system. Studies on preterm birth and asthma risk are comparatively sparse and the results are not consistent. Multivariate analyses were performed on a cross-sectional data from the National Survey of Children’s Health (NSCH...

Nanoencapsulation of Curcumin and Its Protective Effects against CCl4-Induced Hepatotoxicity in Mice

Curcumin is a natural phenolic compound extracted from the herb Curcuma longa L. rhizome and has received much attention on account of its biological properties. However, its poor solubility and low bioavailability limit its use. The purpose of this study was to synthesize curcumin-loaded nanoliposomes (Cur-NLs) to improve their bioavailability and evaluate the hepatoprotective...

Pancreatic kallikrein protects against diabetic retinopathy in KK Cg-Ay/J and high-fat diet/streptozotocin-induced mouse models of type 2 diabetes

Aims/hypothesisMany studies have shown that tissue kallikrein has effects on diabetic vascular complications such as nephropathy, cardiomyopathy and neuropathy, but its effects on diabetic retinopathy are not fully understood. Here, we investigated the retinoprotective role of exogenous pancreatic kallikrein and studied potential mechanisms of action.MethodsWe used KK Cg-Ay/J...

On the Benefits of Semi-Active Suspensions with Inerters

Inerters have become a hot topic in recent years especially in vehicle, train, building suspension systems, etc. Eight different layouts of suspensions were analyzed with a quarter-car model in this paper. Dimensionless root mean square (RMS) responses of the sprung mass vertical acceleration, the suspension travel, and the tire deflection are derived which were used to evaluate...

Adaptive Finite-Time Mixed Interlayer Synchronization of Two-Layer Complex Networks with Time-Varying Coupling Delay

This paper is concerned with two-layer complex networks with unidirectional interlayer couplings, where the drive and response layer have time-varying coupling delay and different topological structures. An adaptive control scheme is proposed to investigate finite-time mixed interlayer synchronization (FMIS) of two-layer networks. Based on the Lyapunov stability theory, a...

Extreme drought in the recent two decades in northern China resulting from Eurasian warming

The analysis of 55-year daily precipitation data reveals prolonging in consecutive dry-day (CDD) and extreme summertime droughts in northern China since the 1990s. Anomalous CDD corresponds to a persistent anticyclone anomaly, that has a significant correlation with enhancing in Eurasian forced waves including Eurasian teleconnection (EU) pattern and Silk Road pattern (SRP...
