    Tracking forest phenology and seasonal physiology using digital repeat photography: a critical assessment.
    Ecol Appl 2014;24(6):1478-89
    Digital repeat photography is becoming widely used for near-surface remote sensing of vegetation. Canopy greenness, which has been used extensively for phenological applications, can be readily quantified from camera images. Important questions remain, however, as to whether the observed changes in canopy greenness are directly related to changes in leaf-level traits, changes in canopy structure, or some combination thereof.

    The hierarchical response of human corneal collagen to load.
    Acta Biomater 2017 Nov 8. Epub 2017 Nov 8.
    School of Optometry and Vision Sciences, Cardiff University, Maindy Road, Cathays, Cardiff CF24 4HQ, UK; Cardiff Institute of Tissue Engineering and Repair, Cardiff University, 10 Museum Place, Cardiff CF10 3BG, UK.
    Fibrillar collagen in the human cornea is integral to its function as a transparent lens of precise curvature, and its arrangement is now well-characterised in the literature. While there has been considerable effort to incorporate fibrillar architecture into mechanical models of the cornea, the mechanical response of corneal collagen to small applied loads is not well understood. In this study the fibrillar and molecular response to tensile load was quantified using small and wide angle X-ray scattering (SAXS/WAXS), and digital image correlation (DIC) photography was used to calculate the local strain field that gave rise to the hierarchical changes.

    Purpose Of Review: The purpose of this study is to review the evidence that lower risk groups who could safely be screened less frequently for sight-threatening diabetic retinopathy (DR) than annually.

    Recent Findings: Data have demonstrated that people with no DR in either eye are at a low risk of progression to sight-threatening DR over a 2-year period (event rate 4.8 per 1000 person years), irrespective of whether the screening method is one-field non-mydriatic or two-field mydriatic digital photography.

    Intraclutch eggshell colour variation in birds: are females able to identify their eggs individually?
    PeerJ 2017 31;5:e3707. Epub 2017 Aug 31.
    Konrad Lorenz Institute of Ethology, Department of Integrative Biology and Evolution, University of Veterinary Medicine, Vienna, Austria.
    Background: One possibility suggested regarding female post-mating strategies is differential allocation into offspring investment. Female birds produce not only the largest, but also most colourful eggs of all oviparous taxa. Larger eggs provide space for bigger embryos, or more nutrition for their development, but the question why eggs are more colourful and why there is variation in eggshell colouration remains.

    From the Department of Neurology, National Medical Center, Seoul, Korea (J.-H.B.); Departments of Radiology (B.M.K., D.J.K.) and Neurology (J.-H.B., J.Y., H.S.N., Y.D.K., J.H.H.), Yonsei University College of Medicine, Seoul, Korea; Department of Neurology, Sungkyunkwan University School of Medicine, Seoul, Korea (O.Y.B.); and Department of Neurology, Keimyung University College of Medicine, Daegu, Korea (J.Y.).
    Background And Purpose: We investigated whether occlusion type identified with computed tomography angiography (CTA-determined occlusion type) could predict endovascular treatment success using stent retriever (SR) thrombectomy.

    Methods: Consecutive patients with stroke who underwent CTA and then endovascular treatment for intracranial large artery occlusion were retrospectively reviewed. CTA-determined occlusion type was classified into truncal-type occlusion or branching-site occlusion and compared with digital subtraction angiography-determined occlusion type during endovascular treatment.

    From the perspective of child-focused nutrition research, the analysis of the school cafeteria culture and environment is critical. Most children eat at least one meal at school per school day, thus elementary schools are a good setting for influencing the early development of healthy eating habits. The salad bar in particular has gained attention as a means of increasing fruit and vegetable consumption. Read More

    Three-dimensional evaluation of the airway spaces in patients with and without cleft lip and palate: A digital volume tomographic study.

    Department of Orthodontics and Dentofacial Orthopedics, Vidya Shikshan Prasarak Mandal's Dental College, Nagpur, India.
    Introduction: Patients with cleft lip and palate (CLP) suffer from several esthetic and functional challenges. Comprehensive treatment of these patients involves orthognathic surgery that may lead to velopharyngeal insufficiency or reduction in lower airway. Several cases of airway insufficiency, velopharyngeal incompetence, snoring, hypopnea, and obstructive sleep apnea have been reported in subjects with CLP. Read More

    Digital Photographic Procedure for Comprehensive Two-Dimensional Tooth Shade Analysis.

    Current commercially available restorative materials vary in their esthetic properties, depending on brand and shade. Variations are related not only to basic color parameters such as hue, chroma, and value, but also to other important properties that affect the overall esthetic restorative outcome, such as opalescence, fluorescence, translucency, and metamerism. Fluorescence and bluish opalescence, though associated with the ingredients and chemical composition of the material, may be controlled and refined by a proper layering technique if that pretreatment analysis has been performed with the aid of appropriate photographic techniques.
