Yanan Zhao, Pak-Kwong Chung
This study examined the associations between walkability related environmental attributes (WREA) and health-related quality of life (HRQoL) among older adults in Hong Kong. A cross-sectional study was conducted among 340 participants (women = 233; mean age = 74.4 years) living in urban communities. Independent variables included residential density, land use mix-diversity, land use mix-access, street connectivity, infrastructure for walking, aesthetics, traffic hazards, crime, access to parking, lack of cul-de-sacs, hilliness, and physical barriers...

Yoav Gimmon, Jennifer Millar, Rebecca Pak, Elizabeth Liu, Michael C Schubert
Gait coordination is generated by neuronal inter-connections between central pattern generators in the spinal cord governed by cortical areas. Malfunction of central vestibular processing areas generates vestibular symptoms in the absence of an identifiable peripheral vestibular system lesion. Walking in the dark enforces a coordinated afference primarily from the vestibular and somatosensory systems. We hypothesized that patients with aberrant central vestibular processing would demonstrate unique gait characteristics, and have impaired gait coordination compared with those patients with abnormal peripheral vestibular function and healthy controls...

Proteomics analysis of chronic cigarette smoke exposure is a rapidly emerging postgenomics research field. While smoking is a major cause of lung cancer, functional studies using proteomics approaches could enrich our mechanistic understanding of the elusive lung cancer global molecular signaling and cigarette smoke relationship. We report in this study on a stable isotope labeling by amino acids in cell culture-based quantitative phosphoproteomic analysis of a human lung mucoepidermoid carcinoma cell line, H292 cells, chronically exposed to cigarette smoke...

REVIEW
Hiroshi Maruta, Mok-Ryeon Ahn
PAK family kinases are RAC/CDC42-activated kinases that were first found in a soil amoeba 4 decades ago, and 2 decades later, were discovered in mammals as well. Since then at least 6 members of this family have been identified in mammals. One of them called PAK1 has been best studied so far, mainly because it is essential not only for malignant cell growth and metastasis, but also for many other diseases/disorders such as diabetes (type 2), AD (Alzheimer's disease), hypertension, and a variety of inflammatory or infectious diseases, which definitely shorten our lifespan...

This is an Editorial for a review that Sosa and coworkers present in the current issue of the Journal of Neurochemistry of physiological functions for amyloid precursor protein (APP) at dynamic cellular contact sites such as growth cones, neuronal migration tracts, and synapses. Here, APP physically links the extracellular and intracellular milieus through a multitude of binding partners. From these observations, the authors offer a model of APP as a cell adhesion molecule in the brain, providing a context for understanding its role in Alzheimer's disease and Down syndrome...

Knowledge of psychiatric disease genetics has advanced rapidly during the past decade with the advent of genome-wide association studies (GWAS). However, less progress has been made in harnessing these data to reveal new therapies. Here we propose a framework for drug repositioning by comparing transcriptomes imputed from GWAS data with drug-induced gene expression profiles from the Connectivity Map database and apply this approach to seven psychiatric disorders. We found a number of repositioning candidates, many supported by preclinical or clinical evidence...

The Drosophila dNab2 protein is an ortholog of human ZC3H14, a poly(A) RNA binding protein required for intellectual function. dNab2 supports memory and axon projection, but its molecular role in neurons is undefined. Here, we present a network of interactions that links dNab2 to cytoplasmic control of neuronal mRNAs in conjunction with the fragile X protein ortholog dFMRP. dNab2 and dfmr1 interact genetically in control of neurodevelopment and olfactory memory, and their encoded proteins co-localize in puncta within neuronal processes...

BACKGROUND: Cadmium translocation from roots to shoots is a complex biological process that is controlled by gene regulatory networks. Pak choi exhibits wide cultivar variations in Cd accumulation. However, the molecular mechanism involved in cadmium translocation and accumulation is still unclear. To isolate differentially expressed genes (DEGs) involved in transporter-mediated regulatory mechanisms of Cd translocation in two contrasting pak choi cultivars, Baiyewuyueman (B, high Cd accumulator) and Kuishan'aijiaoheiye (K, low Cd accumulator), eight cDNA libraries from the roots of two cultivars were constructed and sequenced by RNA-sequencing...

Ictal asystole due to sinus node suppression is a cause of sudden unexplained death in epilepsy. Here, for the first time, we describe a complete atrioventricular nodal block in a patient with non-compressive traumatic subdural hematoma, who developed ictal asystole as a delayed presentation. A leadless VVI pacemaker (ventricular paced, ventricular sensed, and pacing inhibited in response to a sensed beat) was implanted as a preventive measure against seizure-related heart block.

When there is no pulmonary vein reconnection after catheter ablation for atrial fibrillation, patients can experience recurrence of atrial fibrillation without clear evidence of non-pulmonary vein foci. We describe a patient with significant pulmonary vein stenosis and recurrent atrial fibrillation after four ablation procedures. After successful pulmonary vein stenting, the symptoms were resolved, and sinus rhythm was maintained for 2 years without treatment with antiarrhythmic medication. We believe pulmonary vein stenting potentially controlled atrial fibrillation by providing pulmonary vein pressure relief or by compressing the epicardial triggers occurring at the pulmonary vein ostium...

Most Brassicaceae vegetables are ideal dietary sources of antioxidants beneficial for human health. Cardamine fauriei (Ezo-wasabi in Japanese) is a wild, edible Brassicaceae herb native to Hokkaido, Japan. To clarify the main antioxidative phytochemical, an 80% methanol extraction from the leaves was fractionated with Diaion® HP-20, Sephadex® LH-20, and Sep-Pak® C18 cartridges, and the fraction with strong antioxidant activity depending on DPPH method was purified by HPLC. Based on the analyses using HRESIMS and MS/MS, the compound might be N(1), N(14)-diferuloylspermine...

MDA5 is a RIG-I-like cytoplasmic sensor of dsRNA and certain RNA viruses, such as encephalomyocarditis virus, for the initiation of the IFN signaling cascade in the innate antiviral response. The affinity of MDA5 toward dsRNA is low, and its activity becomes optimal in the presence of unknown cellular coactivators. In this article, we report an essential coactivator function of dsRNA-binding protein PACT in mediating the MDA5-dependent type I IFN response. Virus-induced and polyinosinic-polycytidylic acid-induced activation of MDA5 were severely impaired in PACT-knockout cells and attenuated in PACT-knockdown cells, but they were potentiated when PACT was overexpressed...

Subcortical white matter hyperintensities (WMH), presumed to indicate small vessel ischemic vascular disease, are found commonly in elderly individuals with and without Alzheimer's disease (AD). Oxidative stress may instigate or accelerate the development of vascular disease, and oxidative stress markers are elevated in AD. Here, we assess independent relationships between three serum lipid peroxidation markers (lipid hydroperoxides [LPH], 8-isoprostane, and 4-hydroxynonenal) and the presence of extensive subcortical WMH and/or AD...

OBJECTIVE: Late-onset Pompe disease (LOPD) is a lysosomal storage disease resulted from deficiency of the enzyme acid α-glucosidase. Patients usually develop a limb-girdle pattern of myopathy and respiratory impairment, and enzyme replacement therapy (ERT) is the only specific treatment available. Recently, LOPD has been associated with low bone mineral density (BMD), but the effect of ERT on BMD is inconclusive. In this report we described our early observations on the change of BMD after ERT in Chinese LOPD patients...
