Jongsu Lim, Youngmin Yoon, Taesung Hwang, Hee Chun Lee
This study was carried out to derive reference value of normal spine indices, and to evaluate the feasibility of the indices for computed tomography (CT). CT images and magnetic resonance imaging were acquired from clinically normal 12 beagle dogs for normal group and 50 dogs with 56 spinal disorders for patient group. Image acquisition regions were cervical spine (C2 to T1), thoracic spine (T1-T13) and lumbar spine (L1-L7). The measured indices are as follows; the ratio of width to height of spinal cord include dura matter (CR) and vertebral foramen (FR), and the ratio of cross sectional area of spinal cord to vertebral foramen (CFAR)...

Background High-risk sports, particularly climbing, kayaking and extreme skiing, have become increasingly popular. The most widely used psychological survey instrument with regard to risk behaviour in sports is the Sensation Seeking Model, mostly assessed by the Sensation Seeking Scale (SSS-V). Until recently, the literature discussed risk behaviour solely through this model. However, this scale does not measure risk-taking behaviours. In contrast, the Risk-Taking Behaviour Scale (RBS-K) is a three-item scale that measures risk behaviour in high-risk sports...

The aims of this study were to investigate in adolescents: 1) the relationships of physical activity (PA) and cardiorespiratory fitness (CRF) to traditional CVD risk factors, rest and recovery autonomic function; and 2) whether autonomic function strengthens the associations between PA, CRF and CVD risk. Fifty-four (22 girls) adolescents had traditional CVD risk factors, rest and recovery autonomic function evaluated. CRF was measured using a steep ramp cycle test and PA was assessed with accelerometers. Resting HRV (and RMSSD30) and heart rate recovery (T30, HHRτ) were used...

BACKGROUND: A Dissociative Subtype of Posttraumatic Stress Disorder (PTSD) was added to the DSM-5, but little is known about this symptom pattern in young children exposed to trauma. Tailoring treatment to traumatized young children requires understanding the different patterns of trauma-related symptomatology and important correlates. The current study tested the hypothesis that type and number of child traumatic events, caregiver trauma exposure, and caregiver symptomatology would predict whether traumatized young children presented with PTSD, PTSD with clinical dissociation, or non-clinical trauma symptoms...

Peroxidase immobilization onto magnetic supports is considered an innovative strategy for the development of technologies that involves enzymes in wastewater treatment. In this work, magnetic biocatalysts were prepared by immobilization of soybean peroxidase (SBP) onto different silica-coated superparamagnetic iron oxide nanoparticles. The obtained magnetic biocatalysts were tested for the degradation of malachite green (MG), a pollutant often found in industrial wastewaters and with significant drawbacks for the human and environmental health...

Soluble epoxide hydrolase (sEH) inhibition is reported to elevate endogenous epoxyeicosatrienoic acids (EET's), which are known to play an important role in neuroprotection by inhibiting oxidative stress and neuroinflammation. In the present study, PTUPB, a dual inhibitor of sEH and COX-2, has been tested for its antiparkinson activity against rotenone (ROT) induced neurodegeneration in Drosophila model of Parkinson's disease (PD). To determine the efficacy and brain bioavailability of PTUPB a simple, rapid and sensitive LC-MS/MS method was developed and validated for the estimation of PTUPB (Method-I), dopamine (DA) and its metabolites (Method-II) in fly head...

When evaluating new morally complex health technologies, policy decision-makers consider a broad range of different evaluations, which may include the technology's clinical effectiveness, cost effectiveness, and social or ethical implications. This type of holistic assessment is challenging, because each of these evaluations may be grounded in different and potentially contradictory assumptions about the technology's value. One such technology where evaluations conflict is Non-Invasive Prenatal Testing (NIPT)...

Despite mounting evidence on the importance of fathers in children's development, evidence-based perinatal home visitation programs have largely overlooked fathers in the design and delivery of services. This paper describes the design, development, and pilot testing of the "Dads Matter" enhancement to standard home visiting services. Dads Matter is a manualized intervention package designed to fully incorporate fathers into perinatal home visiting services. Twenty-four families were enrolled in a pilot study to assess the feasibility, acceptability, and preliminary outcomes of the intervention...

In this study, we aimed to investigate the protective effects of androgens, using letrozole (LET; an aromatase inhibitor), grape seed extract (GSE; a naturally occurring aromatase inhibitor and antioxidant), and testosterone propionate (Tp), against methotrexate (MTX)-induced testicular toxicity in adult male rats. MTX has been shown to induce oxidative stress and exhibit antiproliferative effects in the testes. Adult male rats received oral saline gavage (control group with no treatment), the potential protective agents (LET, GSE, or Tp) alone, MTX alone, or a combination of one of the potential protective agents and MTX...

BACKGROUND: Cognitive impairment is a common nonmotor manifestation of Parkinson's disease, with deficits ranging from mild cognitive difficulties in 1 or more of the cognitive domains to severe dementia. The International Parkinson and Movement Disorder Society commissioned the assessment of the clinimetric properties of cognitive rating scales measuring global cognitive performance in PD to make recommendations regarding their use. METHODS: A systematic literature search was conducted to identify the scales used to assess global cognitive performance in PD, and the identified scales were reviewed and rated as "recommended," "recommended with caveats," "suggested," or "listed" by the panel using previously established criteria...

REVIEW
Niloofar Shoari, Jean-Sébastien Dubé
Various statistical tests on concentration data serve to support decision-making regarding characterization and monitoring of contaminated media, assessing exposure to a chemical, and quantifying the associated risks. However, the routine statistical protocols cannot be directly applied because of challenges arising from nondetects or left-censored observations that are concentration measurements below detection limit of measuring instruments. Despite the existence of techniques based on survival analysis that can adjust for nondetects, these are seldom taken into account properly...

Herein, a templated borate, [Emmim][B5O6(OH)4] (denoted 1, Emmim = 1-ethyl-2,3-dimethylimidazolium), has been synthesized. It is unexpectedly observed that 1 exhibits a series of broadened luminescence curves from -183 to 75 °C, the emission intensities are measured as a decreasing function of temperature, and the line width of the PL emission is strongly enhanced when temperatures decrease below -100 °C. In addition to this, hydrogen bonding (H-B) in 1 with distinctly enlarging trends was observed as the temperature increased...

Three-dimensional 45S5 bioactive glass (BG)-based scaffolds are being investigated for bone regeneration. Besides structural properties, controlled time-dependent alteration of scaffold morphology is crucial to achieve optimal scaffold characteristics for successful bone repair. There is no in vitro evidence concerning the dependence between structural characteristics and dissolution behavior of 45S5 BG-based scaffolds of different morphology. In this study, the dissolution behavior of scaffolds fabricated by the foam replica method using polyurethane foam (Group A) and maritime sponge Spongia Agaricina (Group B) as sacrificial templates was analyzed by micro-computed-tomography (µCT)...
