#1
Shuhua Bian, Zjian Hu, Jianqiang Liu, Zichen Zhu
The suspension and hydrodynamic characteristics of the Yellow River Delta during storms were analyzed based on suspended samples obtained using automatic samplers during a storm event in the Yellow River Delta. Synchronous data for winds, waves, and tides were also collected from a nearby station. The results show that under wind speeds of 5-15 m/s and wave heights of 50-150 cm, the suspended content reached 5.7-49.6 kg/m(3), which is 10-100 times higher than that under normal weather conditions. The medium diameter of suspended particles was 1...

Pelargonium line pattern virus (PLPV, Tombusviridae) normally establishes systemic, low-titered and asymptomatic infections in its hosts. This type of interaction may be largely determined by events related to RNA silencing, a major antiviral mechanism in plants. This mechanism is triggered by double or quasi double-stranded (ds) viral RNAs which are cut by DCL ribonucleases into virus small RNAs (vsRNAs). Such vsRNAs are at the core of the silencing process as they guide sequence-specific RNA degradation Host RNA dependent-RNA polymerases (RDRs), and particularly RDR6, strengthen antiviral silencing by promoting biosynthesis of secondary vsRNAs...

In 2001, the World Health Assembly (WHA) passed the landmark WHA 54.19 resolution for global scale-up of mass administration of anthelmintic drugs for morbidity control of schistosomiasis and soil-transmitted helminthiasis, which affect more than 1·5 billion of the world's poorest people. Since then, more than a decade of research and experience has yielded crucial knowledge on the control and elimination of these helminthiases. However, the global strategy has remained largely unchanged since the original 2001 WHA resolution and associated WHO guidelines on preventive chemotherapy...

In the process of biomaterials mediated bone regeneration, rhBMP-2 delivery at efficient dose in sustained kinetics is crucial for promoting cell osteogenic differentiation. Meanwhile, surface morphology of the biomaterials could regulate cellular responses as well as strengthen the rhBMP-2 interaction with cells for better bone induction. Herein, TiO2 nanorod films with varied mesoporous bioactive glass (MBG) incorporation amount were designed to strengthen the efficacy of rhBMP-2, basing on optimized loading/release behaviors and surface nanostructure cooperatively...

Leisure is an important quality of life factor for older Korean immigrants. The purpose of this study was to explore leisure benefits associated with health among older Korean immigrants. A total of 18 individuals participated in the study. Using interpretative phenomenological analysis (IPA), three themes emerged from participants' personal statements and experiences: (a) experiencing psychological benefits, (b) strengthening social connections, and (c) coping with acculturative stress. The findings indicate that leisure provided a context in which older Korean immigrants created an emotional and social support system that helped them to experience psychological and social benefits...

REVIEW
Peter M Stevens
For decades, the classic indication for limb lengthening has been reserved for anisomelia that was expected to reach or exceed 5 cm at maturity. Epiphysiodesis was reserved for discrepancies in the 2-5 cm range. With the increasing sophistication of fixators, including rail, hexapod, and hybrid, complex deformities may be corrected simultaneously while moderate to extreme lengthening is achieved. More recently, iterations of telescoping intramedullary rods have further strengthened our armamentarium. Meanwhile, permanent epiphysiodesis techniques, both open and percutaneous, have yielded to more versatile and reversible tethering of one (angle) or both (length) sides of a physis...

Five-prime repressor element under dual repression binding protein-1 (Freud-1)/CC2D1A is genetically linked to intellectual disability and implicated in neuronal development. Freud-1 represses the serotonin-1A (5-HT1A) receptor gene HTR1A by histone deacetylase (HDAC)-dependent or HDAC-independent mechanisms in 5-HT1A-negative (e.g., HEK-293) or 5-HT1A-expressing cells (SK-N-SH), respectively. To identify the underlying mechanisms, Freud-1-associated proteins were affinity-purified from HEK-293 nuclear extracts and members of the Brg1/SMARCCA chromatin remodeling and Sin3A-HDAC corepressor complexes were identified...

Leucine-rich repeat kinase 2 (LRRK2) is a central protein in the pathogenesis of Parkinson's disease (PD), yet its normal function has proved stubbornly hard to elucidate. Even though it remains unclear how pathogenic mutations affect LRRK2 to cause PD, recent findings provide increasing cause for optimism. We summarise here the developing consensus over the effect of pathogenic mutations in the Ras of complex proteins and C-terminal of Roc domains on LRRK2 GTPase activity. This body of work has been greatly reinforced by our own study of the protective R1398H variant contained within the LRRK2 GTPase domain...

Remote points-of-care has recently had a lot of attention for their advantages such as saving lives and cost reduction. The transmitted streams usually contain (1) normal biomedical signals (e.g. ECG) and (2) highly private information (e.g. patient identity). Despite the obvious advantages, the primary concerns are privacy and authenticity of the transferred data. Therefore, this paper introduces a novel steganographic mechanism that ensures (1) strong privacy preservation of private information by random concealing inside the transferred signals employing a key, and (2) evidence of originality for the biomedical signals...

This study aimed to assess the effects of Basagran(®) on zebrafish (Danio rerio) embryos. The embryos were exposed to Basagran(®) at concentrations ranging from 120.0 to 480.6 mg/L, and the effects on embryo development (up to 96 h) and bacterial communities of 96 h-larvae were assessed. The embryo development response was time-dependent and concentration-dependent (106.35 < EC50 < 421.58 mg/L). The sensitivity of embryo-related endpoints decreased as follows: blood clotting in the head and/or around the yolk sac > delay or anomaly in yolk sac absorption > change in swimming equilibrium > development of pericardial and/or yolk sac oedema > scoliosis...

Annie Ross, Alison J Yarnall, Lynn Rochester, Sue Lord
BACKGROUND: Falls are a major problem for people with Parkinson's disease (PD). Despite years of focused research knowledge of falls aetiology is poor. This may be partly due to classification approaches which conventionally report fall frequency. This nosology is blunt, and does not take into account causality or the circumstances in which the fall occurred. For example, it is likely that people who fall from a postural transition are phenotypically different to those who fall during high level activities...

In the aftermath of the Ebola crisis and with renewed attention to resilient health systems, the process of improving approaches of global health actors to health systems strengthening is of great relevance. Despite the increased amount of attention paid to health systems strengthening, there is no standard definition of this concept among global health actors. Germany is no exception. Though there have been recent commitments to increase resources allocated to health systems strengthening, German Development Cooperation has no comprehensive strategy for its pursuit...
