Habitat fragmentation is typically seen as inhibiting movement via erosion in connectivity, although some patterns of early-phase disturbance, such as narrow linear disturbances in otherwise undisturbed forests, may actually facilitate the dispersal of certain species. Such features are common in Alberta's oil sands region as legacies from seismic hydrocarbon exploration used to map oil reserves. Many of the ecological implications of these disturbances are unknown. Here, we investigate the effect of these forest dissections by experimentally testing dispersal patterns along seismic lines compared with adjacent forests using two proxy materials for wind-dispersed seeds, Typha latifolia seed and goose down feathers...

The effect of ambient air pollution exposure on childhood hypertension has emerged as a concern in China, and previous studies suggested pet ownership is associated with lower blood pressure (BP). However, limited information exists on the interactive effects pet ownership and air pollution exposure has on hypertension. We investigated the interactions between exposure to pet ownership and air pollutants on hypertension in Chinese children. 9354 students in twenty-four elementary and middle schools (aged 5-17 years) in Northeastern China were evaluated during 2012-2013...

Mandibular distraction osteogenesis (MDO) is an effective treatment modality for children suffering from upper airway obstruction from Robin Sequence (RS). Mandibular distraction osteogenesis has been shown to have positive effects on oral feeding and for relieving respiratory obstruction, but its effects on postoperative weight gain are poorly understood. This study quantitatively analyzes weight gain following MDO. A retrospective chart review identified 22 RS children who underwent MDO. Patient weight data, feeding methods pre- and postoperatively, and polysomnography data pre- and postoperatively were collected...

Picture naming impairments are a typical feature of stroke-induced aphasia. Overall accuracy and rates of different error types are used to make inferences about the severity and nature of damage to the brain's language network. Currently available assessment tools for picture naming accuracy treat it as a unidimensional measure, while assessment tools for error types treat items homogenously, contrary to findings from psycholinguistic investigations of word production. We created and tested a new cognitive psychometric model for assessment of picture naming responses, using cognitive theory to specify latent processing decisions during the production of a naming attempt, and using item response theory to separate the effects of item difficulty and participant ability on these internal processing decisions...

BACKGROUND: Elevated lipoprotein(a) (Lp(a)) levels are associated with increased risk for atherosclerotic cardiovascular disease (ASCVD). Individuals with a family history of premature ASCVD are at increased cardiovascular risk with concomitantly a higher burden of (subclinical) atherosclerosis. However, whether Lp(a) contributes to the increased atherosclerotic burden in these individuals remains to be established. OBJECTIVE: In this study, we evaluated the association between Lp(a) levels and coronary atherosclerotic burden, assessed by coronary arterty calcium (CAC) scores, in asymptomatic individuals with a family history of premature ASCVD...

Visceral pleural invasion (VPI) in stageI lung adenocarcinoma is an independent negative prognostic factor. However, no studies proved any morphologic pattern could be referred to as a prognostic factor. Thus, we aim to investigate the potential prognostic impact of VPI by extracting high-dimensional radiomics features on thin-section computed tomography (CT). A total of 327 surgically resected pathological-N0M0 lung adenocarcinoma 3 cm or less in size were evaluated. Radiomics signature was generated by calculating the contribution weight of each feature and validated using repeated leaving-one-out ten-fold cross-validation approach...
