Anisotropy and Spatial Heterogeneity in Quantitative Ultrasound Parameters: Relevance to the Study of the Human Cervix.

Imaging biomarkers based on quantitative ultrasound can offer valuable information about properties that inform tissue function and behavior such as microstructural organization (e.g., collagen alignment) and viscoelasticity (i.

Cancer and Complementary Therapies: Current Trends in Survivors' Interest and Use.

Background: Cancer survivors use complementary therapies (CTs) for a variety of reasons; however, with interest and use reportedly on the rise and a widening range of products and practices available, there is a need to establish trends in and drivers of interest. We aimed to determine (1) frequencies of use, level of interest, and barriers for 30 specific CTs and (2) whether physical symptoms, perceived stress (PS), or spiritual well-being were related to interest levels.

Method: A total of 212 cancer outpatients were surveyed at the Tom Baker Cancer Centre in Calgary, Canada.

Ultrasonication-assisted synthesis of high aspect ratio gold nanowires on a graphene template and investigation of their growth mechanism.

We report a facile synthesis of Au nanowires (AuNWs) with a high aspect ratio (l/D) of up to 5000 on a plasma activated graphene template with ultrasound assistance. We demonstrate that the ultrasonication induced symmetry breaking of Au clusters facilitates the growth of AuNWs from the embryonic stages. Furthermore, the growth mechanism of AuNWs is systematically investigated using high resolution electron transmission microscopy (HRTEM), which reveals the unique role of the defective graphene template in directing the growth of AuNWs.

Inter-process relations in spatial language: Feedback and graded compatibility.

Mapping spatial expressions such as "behind the cup" to a spatial region requires two processes that have been largely explored independently: reference frame selection and spatial term assignment (Logan & Sadler, 1996). Reference frame selection carves a space into regions. Spatial term assignment evaluates these regions by determining the acceptability of the term for the given configuration.

Direct effects of warming increase woody plant abundance in a subarctic wetland.

Both the direct effects of warming on a species' vital rates and indirect effects of warming caused by interactions with neighboring species can influence plant populations. Furthermore, herbivory mediates the effects of warming on plant community composition in many systems. Thus, determining the importance of direct and indirect effects of warming, while considering the role of herbivory, can help predict long-term plant community dynamics.

Quantitative assessment of cervical softening during pregnancy in the Rhesus macaque with shear wave elasticity imaging.

Abnormal parturition, e.g. pre- or post-term birth, is associated with maternal and neonatal morbidity and increased economic burden.

Alberta CancerBridges development of a care plan evaluation measure.

Background: No standardized measures specifically assess cancer survivors' and healthcare providers' experience of Survivor Care Plans (scps). We sought to develop two care plan evaluation (cpe) measures, one for survivors (cpe-s) and one for healthcare providers (cpe-p), examine initial psychometric qualities in Alberta, and assess generalizability in Manitoba, Canada.

Methods: We developed the initial measures using convenience samples of breast ( = 35) and head and neck ( 18) survivors who received scps at the end of active cancer-centre treatment.

Residential green space and birth outcomes in a coastal setting.

Background: Residential green space may improve birth outcomes, with prior studies reporting higher birthweight among infants of women living in greener areas. However, results from studies evaluating associations between green space and preterm birth have been mixed. Further, the potential influence of residential proximity to water, or 'blue space', on health has not previously been evaluated.

Maternal Malignancy Evaluation After Discordant Cell-Free DNA Results.

Cell-free DNA screening for fetal aneuploidy is a commonly used testing strategy in pregnancies at high risk for fetal aneuploidy. The use of cell-free DNA screening is expanding to the low-risk population, because the detection rate for trisomy 21 surpasses that of traditional screening modalities. Although the sensitivity and specificity of cell-free DNA are superior to traditional screening, false-positive results do occur and may indicate an adverse maternal health condition, including maternal mosaicism or, rarely, malignancy.

One-Step Synthesis of Tunable-Size Gold Nanoplates on Graphene Multilayers.

Au nanoplates (quasi-two-dimensional single crystals) are most commonly synthesized using a mixture of Au precursors via approaches involving multiple processing steps and the use of seed crystals. Here, we report the synthesis of truncated-hexagonal {111}-oriented micrometer-scale Au nanoplates on graphene multilayers using only potassium tetrabromoaurate (KAuBr) as the precursor. We demonstrate that the nanoplate sizes can be controllably varied from tens of nanometers up to a few micrometers by introducing desired concentrations of chloroauric acid (HAuCl) to KAuBr and their thicknesses from ∼13 to ∼46 nm with the synthesis time.

Open to Exploration? Association of Personality Factors With Complementary Therapy Use After Breast Cancer Treatment.

Purpose: Many cancer survivors seek complementary therapies (CTs) to improve their quality of life. While it is well-known that women who are younger, more highly educated, and have higher incomes are more likely to use CTs, individual differences such as personality factors have been largely unexplored as predictors of CT use.

Methods: In a secondary analysis of a larger study, 270 women with stage I to III breast cancer completed self-report measures of demographic and illness-related information, personality variables, and use of several different types of CTs.

Graphene template-induced growth of single-crystalline gold nanobelts with high structural tunability.

Assembling Au nanocrystals with tunable dimensions and shapes on graphene templates has attracted increasing attention recently. However, directly growing anisotropic Au nanobelts on a graphene support has been rarely reported. Here, a facile, one-pot, and surfactant-free route is demonstrated to synthesize well-defined Au nanobelts with the induction of a multilayer graphene (mlG) template.

Climate patterns and mosquito-borne disease outbreaks in South and Southeast Asia.

Background: Vector-borne infectious diseases, particularly mosquito-borne, pose a substantial threat to populations throughout South and Southeast Asia. Outbreaks have affected this region several times during the early years of the 21st century, notably through outbreaks of Chikungunya and Dengue. These diseases are believed to be highly prevalent at endemic levels in the region as well.

Intra-articular Triamcinolone Versus Hyaluronate Injections for Low Back Pain With Symptoms Suggestive of Lumbar Zygapophyseal Joint Arthropathy: A Pragmatic, Double-Blind Randomized Controlled Trial.

Objective: The aim of the study was to compare hyaluronate with triamcinolone injections in treating chronic low back pain suggestive of lumbar zygopophyseal joint arthropathy.

Design: This was a prospective, double-blind, randomized controlled trial. Thirty subjects were randomly assigned to receive bilateral L3-S1 lumbar zygopophyseal joint injections with triamcinolone (KA) or Synvisc-One (HA).

Detection of Changes in Cervical Softness Using Shear Wave Speed in Early versus Late Pregnancy: An in Vivo Cross-Sectional Study.

The aim of this study was to assess the ability of shear wave elasticity imaging (SWEI) to detect changes in cervical softness between early and late pregnancy. Using a cross-sectional study design, shear wave speed (SWS) measurements were obtained from women in the first trimester (5-14 wk of gestation) and compared with estimates from a previous study of women at term (37-41 wk). Two sets of five SWS measurements were made using commercial SWEI applications on an ultrasound system equipped with a prototype catheter transducer (128 elements, 3-mm diameter, 14-mm aperture).

Best-Matched Internal Standard Normalization in Liquid Chromatography-Mass Spectrometry Metabolomics Applied to Environmental Samples.

The goal of metabolomics is to measure the entire range of small organic molecules in biological samples. In liquid chromatography-mass spectrometry-based metabolomics, formidable analytical challenges remain in removing the nonbiological factors that affect chromatographic peak areas. These factors include sample matrix-induced ion suppression, chromatographic quality, and analytical drift.

How the physicality of space affects how we think about time.

Time is an abstract concept that may be better understood when mapped onto space. For English speakers, typically a timeline is used that runs horizontally from left (past) to right (future) (Boroditsky, Fuhrman, & McCormick, 2011) and can be separated into regions, past and future. However, it is unclear from prior research how these regions along the timeline are differentiated.

Albeit nocturnal, rats subjected to traumatic brain injury do not differ in neurobehavioral performance whether tested during the day or night.

Behavioral assessments in rats are overwhelmingly conducted during the day, albeit that is when they are least active. This incongruity may preclude optimal performance. Hence, the goal of this study was to determine if differences in neurobehavior exist in traumatic brain injured (TBI) rats when assessed during the day vs.

Tai Chi and Qigong for cancer-related symptoms and quality of life: a systematic review and meta-analysis.

Purpose: This study aims to summarize and critically evaluate the effects of Tai Chi and Qigong (TCQ) mind-body exercises on symptoms and quality of life (QOL) in cancer survivors.

Methods: A systematic search in four electronic databases targeted randomized and non-randomized clinical studies evaluating TCQ for fatigue, sleep difficulty, depression, pain, and QOL in cancer patients, published through August 2016. Meta-analysis was used to estimate effect sizes (ES, Hedges' g) and publication bias for randomized controlled trials (RCTs).

New techniques in evaluation of the cervix.

The process of parturition is poorly understood, but the cervix clearly plays a key role. Because of this, recent research efforts have been directed at objective quantification of cervical remodeling. Investigation has focused on two basic areas: (1) quantification of tissue deformability and (2) presence, orientation, and/or concentration of microstructural components (e.

Distress Management Through Mind-Body Therapies in Oncology.

Distress is highly prevalent in cancer survivors, from the point of diagnosis through treatment and recovery, with rates higher than 45% reported worldwide. One approach for helping people cope with the inherent stress of cancer is through the use of mind-body therapies (MBTs) such as mediation, yoga, hypnosis, relaxation, and imagery, which harness the power of the mind to affect physical and psychological symptoms. One group of MBTs with a growing body of research evidence to support their efficacy focus on training in mindfulness meditation; these are collectively known as mindfulness-based interventions (MBIs).

Bright light therapy improves cancer-related fatigue in cancer survivors: a randomized controlled trial.

Purpose: Cancer-related fatigue (CRF) is a common and distressing symptom that can persist after cancer treatment has concluded. Bright light therapy has shown preliminary efficacy in reducing CRF, but its impact on other psychosocial factors is unclear. The purpose was to examine the impact of a 1-month light therapy intervention on fatigue, mood, and quality of life in cancer survivors with fatigue.

Ten-Year Minimum Follow-Up of 4-Corner Fusion for SLAC and SNAC Wrist.

Background: Scapholunate advanced collapse (SLAC) of the wrist is the most common degenerative condition of the wrist. Four-corner fusion (4CF) is performed as salvage surgery, though there is limited information on its long-term results. We hypothesized that 4CF is a durable surgery with good clinical long-term function.
