#1
Ryoichi Kose, Katsumi Kose
A magnetic resonance imaging (MRI) simulator, which reproduces MRI experiments using computers, has been developed using two graphic-processor-unit (GPU) boards (GTX 1080). The MRI simulator was developed to run according to pulse sequences used in experiments. Experiments and simulations were performed to demonstrate the usefulness of the MRI simulator for three types of pulse sequences, namely, three-dimensional (3D) gradient-echo, 3D radio-frequency spoiled gradient-echo, and gradient-echo multislice with practical matrix sizes...

Negative environmental impact of coal combustion has been known to humankind for a fairly long time. Sulfur and nitrogen oxides are considered the most dangerous anthropogenic emissions. A possible solution to this problem is replacing coal dust combustion with that of coal water slurry containing petrochemicals (CWSP). Coal processing wastes and used combustible liquids (oils, sludge, resins) are promising in terms of their economic and energy yield characteristics. However, no research has yet been conducted on the environmental indicators of fuels based on CWSP...

BACKGROUND: Within academic psychiatry, women are underrepresented in the higher academic ranks. However, basic determinants of women's lack of academic advancement such as publication activity are poorly understood. The present study examines women's publication activity in high-impact psychiatry journals over two decades and reports developments in the numbers of male and female authorship over time and across cultural areas. METHODS: We conducted a retrospective bibliometric review of all articles published in 2004 and 2014 in three high-ranking general psychiatry journals...

Forensic age estimation research based on skeletal structures focuses on patterns of growth and development using different bones. In this work, our aim was to study growth-related evolution of the manubrium in living adolescents and young adults using magnetic resonance imaging (MRI), which is an image acquisition modality that does not involve ionizing radiation. In a first step, individual manubrium and subject features were correlated with age, which confirmed a statistically significant change of manubrium volume (Mvol:p<0...

REVIEW
T Tritschler, D Aujesky
Persons aged ≥65years not only account for over 60% of venous thromboembolism (VTE) events, they have also a higher mortality and VTE-related morbidity than younger patients, including anticoagulation-related bleeding and the postthrombotic syndrome. However, only few studies have focused specifically on VTE in older persons and practice guidelines commonly extrapolate study results from younger healthier patients to the multimorbid elderly. Evidence suggests that the clinical presentation is more subtle in the elderly with VTE and that commonly used diagnostic modalities, including clinical prediction rules, D-dimer tests, and planar ventilation-perfusion scans are less specific and efficient in older persons...

The present study investigated the validity of the 25-item Driving Anger Expression Inventory (DAX) as well as the role of sex and gender-roles in relation to the expression of driving anger in a sample of 378 French drivers (males=38%, M=32.9years old). Confirmatory Factor Analysis supported the four-factor structure of the 25-item DAX (Adaptive/Constructive Expression; Use of the Vehicle to Express Anger; Verbal Aggressive Expression and Personal Physical Aggressive Expression) and two of the three aggressive factors were found to have significant positive relationships with driving anger, while adaptive/constructive expression was negatively related to driving anger...

Sibling relationships in foster care settings have received increased attention in recent years. Despite growing evidence regarding the protective potential of sibling relationships for youth in care, some sibling groups continue to experience foster care related separation, and few programs exist to address the needs of these youth. This study describes and evaluates Camp To Belong, a multi-site program designed to provide short-term reunification to separated sibling groups through a week-long summer camp experience...

Chronic ultraviolet radiation (UV-R) exposure causes skin disorders like erythema, edema, hyperpigmentation, photoaging and photocarcinogenesis. Recent research trends of researchers have focused more attention on the identification and use of photo stable natural agents with photoprotective properties. Piperine (PIP), as a plant alkaloid, is an important constituent present in black pepper (Piper nigrum), used widely in ayurvedic and other traditional medicines and has broad pharmacological properties. The study was planned to photoprotective efficacy of PIP in human keratinocyte (HaCaT) cell line...

Ethanamizuril (EZL) is a novel anti-coccidial triazine synthesized by the Shanghai Veterinary Research Institute of the Chinese Academy of Agricultural Sciences. As a novel coccidiostat, it is essential to study its residue in food animal tissues. In this study, a reliable UPLC method for the determination of ethanamizuril (EZL) and one of its metabolites (M3) in chicken muscle, skin and fat, liver, and kidney samples was developed. Analytes were extracted using acetonitrile and 10% sodium carbonate solution, defatted by n-hexane, and further purified by using an Oasis MCX cartridge...

An extensive body of research theorises that attachment to place is positively associated with health, particularly for older people. Building on this, we measure how indicators of attachment to place are associated with health for in people of advanced age in New Zealand. We use data from a cohort study (LiLACS NZ), which includes an indigenous Māori cohort aged 80-90 years and a non-Māori cohort aged 85 years from a mixed urban/rural region in New Zealand. Each cohort undertook a comprehensive interview and health assessment (n = 267 Māori and n = 404 non-Māori)...

As one of the most ethnically diverse countries in the world, Canada is faced with numerous challenges in addressing disparities affecting its healthcare system. One barrier to care is limited English proficiency (LEP). Using electronic medical records, this retrospective study examined the impact of LEP on inpatient length of stay (LOS) in an acute care community hospital. We found that patients in our sample population with LEP had a shorter inpatient LOS by 0.36 days compared with English-proficient (EP) patients...

Canadians' health and its care continue to evolve. Chronic diseases affect more than 50% of our aging population, but the majority of public and professional stakeholders retain a sense of care quality. An emergent issue, however, is generating an increasingly wide debate. It is the concept of patient-centred care, including its definition of key components, and efficacy. To advance the evidence base, the 2013-2014 and 2016 Health Care in Canada (HCIC) surveys measured pan-stakeholder levels of support and implementation priorities for frequently proposed components of patient centricity in healthcare...

This paper presents highlights from a program of research addressing sex and gender among persons with traumatic brain injury (TBI) relevant to the Canadian context. Epidemiological trends based on health administrative data are examined, and their implications for policy and practice are considered. Further, the authors discuss the need to proactively address TBI in marginalized populations and in the workplace, two areas that have not received widespread attention.

Long noncoding RNAs (lncRNAs), as new class of functional regulators involved in human tumorigenesis, have been attracting increasing attention of researchers. The lncRNA Colorectal Neoplasia Differentially Expressed (CRNDE), transcribed from chromosome 16 on the strand opposite to the adjacent IRX5 gene, were originally found to be increased in CRC and was reported abnormal expressed in many cancers. However, its potential role and molecular mechanism underlying radioresistant phenotype formation of lung adenocarcinoma (LAD) remains unclear...

Segmented filamentous bacterium (SFB) a gram-positive, anaerobic, and intestinal commensal organism directly influencesthe development of Th17 helper cells in the small intestine of mice. In NOD mice, SFB colonization interferes with the developmentof type 1 diabetes (T1D), a T-cell-mediated autoimmune disease, suggesting that SFB may influence Th17 cells to inhibit Th1populations associated with the anti-β-cell immune response. This effect is a serious concern for investigators who use NOD micefor diabetes research because the expected incidence of disease decreases markedly when they are colonized by SFB...

Adenosquamous lung carcinoma (ASC) is an uncommon entity of the primary lung cancer, which is mixed by adenocarcinoma and squamous carcinoma cells. ASC not only possesses the malignant biological characteristics of adenocarcinoma and squamous cell carcinoma, but also exhibits special clinical features, such as the higher malignant degree and poorer prognosis. This paper is aimed to elaborate the research process of the pathological origin of ASC, the application of different diagnostic methods in ASC, various therapeutic strategies and its associated prognosis so as to help to develop the clinical strategies of ASC...

Geoff Hollis
Best-worst scaling is a judgment format in which participants are presented with a set of items and have to choose the superior and inferior items in the set. Best-worst scaling generates a large quantity of information per judgment because each judgment allows for inferences about the rank value of all unjudged items. This property of best-worst scaling makes it a promising judgment format for research in psychology and natural language processing concerned with estimating the semantic properties of tens of thousands of words...

Residential mobility and type of housing contributes to an individual's likelihood and frequency of drug/alcohol use and committing criminal offenses. Little research has focused simultaneously on the influence of housing status on the use of drugs and criminal behavior. The present study examines how residential mobility (transitions in housing) and recent housing stability (prior 30 days) correlates with self-reported criminal activity and drug/alcohol use among a sample of 504 addicted, treatment-seeking opioid users with a history of criminal justice involvement...
