    Developing a digital photography-based method for dietary analysis in self-serve dining settings.
    Appetite 2017 Apr 2;114:217-225. Epub 2017 Apr 2.
    Department of Agricultural and Consumer Economics, University of Illinois, 1301 W. Gregory, Urbana, IL 61801, United States. Electronic address:
    Current population-based methods for assessing dietary intake, including food frequency questionnaires, food diaries, and 24-h dietary recall, are limited in their ability to objectively measure food intake. Digital photography has been identified as a promising addition to these techniques but has rarely been assessed in self-serve settings. We utilized digital photography to examine university students' food choices and consumption in a self-serve dining hall setting. Read More

So, the diagnosis of cervical artery has become a great challenge. Read More

    Expert Consensus on Cosmetic Outcomes After Treatment of Actinic Keratosis.
    J Drugs Dermatol 2017 Mar;16(3):260-264

    Dermatologists treat actinic keratosis (AK) primarily because these lesions have the potential to progress to invasive squamous cell carcinoma. Patients, on the other hand, generally seek treatment to remove the lesions and achieve an improved appearance of their skin following treatment. In selecting a treatment option for AK, dermatologists should consider post-treatment cosmesis, because cosmetic outcomes differ across AK treatments. Read More

    Site-based data curation based on hot spring geobiology.
    PLoS One 2017 2;12(3):e0172090. Epub 2017 Mar 2.
    Department of Geology, University of Illinois Urbana-Champaign, Urbana, Illinois United States of America.
    Site-Based Data Curation (SBDC) is an approach to managing research data that prioritizes sharing and reuse of data collected at scientifically significant sites. The SBDC framework is based on geobiology research at natural hot spring sites in Yellowstone National Park as an exemplar case of high value field data in contemporary, cross-disciplinary earth systems science. Through stakeholder analysis and investigation of data artifacts, we determined that meaningful and valid reuse of digital hot spring data requires systematic documentation of sampling processes and particular contextual information about the site of data collection.

    This article reviews the critical aspects of controlling the shade-taking environment and discusses various modalities introduced throughout the years to acquire and communicate shade information. Demonstrating a highly calibrated digital photographic technique for capturing shade information, this article shows how to use Photoshop® to standardize images and extract color information from the tooth and shade tab for use by a ceramist for an accurate shade-matching restoration.

    Noninvasive computed tomography angiography (CTA) is widely used in acute ischemic stroke, even for diagnosing various internal carotid artery (ICA) occlusion sites, which often need cerebral digital subtraction angiography (DSA) confirmation. We evaluated whether clinical outcomes vary depending on the DSA-based occlusion sites and explored correlating features on baseline CTA that predict DSA-based occlusion site.We analyzed consecutive patients with acute ICA occlusion who underwent DSA and CTA.

    X-ray dose reduction using additional copper filtration for abdominal digital radiography: Evaluation using signal difference-to-noise ratio.
    Phys Med 2017 Feb 29;34:65-71. Epub 2017 Jan 29.
    Division of Health Sciences, Graduate School of Medical Sciences, Kanazawa University,Japan.
    Purpose: X-ray dose reduction using additional copper filters (Cu-filters) for abdominal general radiography was indicated in a report using a simulation study. We validated the dose reduction effects using a clinical digital radiography system equipped with an indirect-type CsI detector and an automatic Cu-filter insertion function.

    Methods: The image qualities were evaluated using signal difference-to-noise ratio (SDNR) for different radiation qualities with and without Cu-filters for a 20-cm acrylic phantom. Read More

    VirtoScan - a mobile, low-cost photogrammetry setup for fast post-mortem 3D full-body documentations in x-ray computed tomography and autopsy suites.

    Injuries such as bite marks or boot prints can leave distinct patterns on the body's surface and can be used for 3D reconstructions. Although various systems for 3D surface imaging have been introduced in the forensic field, most techniques are both cost-intensive and time-consuming. In this article, we present the VirtoScan, a mobile, multi-camera rig based on close-range photogrammetry. Read More

    Testing of bioactive-nanovesicles on hepatotoxicity of atypical antipsychotics via digital holography.

    Atypical antipsychotic drugs induce hepatic toxicity. Thus, it is of importance to eliminate the side effects of these drugs. Herein we describe the preparation of nanoemulsions with a dietary supplement; wheat germ oil (WGO), to ameliorate the liver damage induced by clozapine and olanzapine. Read More

    A novel cosmetic antifungal/anti-inflammatory topical gel for the treatment of mild to moderate seborrheic dermatitis of the face: a open-label trial utilizing clinical evaluation and erythemadirected digital photography.
    G Ital Dermatol Venereol 2017 Jan 24. Epub 2017 Jan 24.
    Dermatology Clinic, University of Catania, Catania, Italy -
    Bakground: Topical cosmetic agents may play a role in the management of facial seborrheic dermatitis by reducing inflammation and scale production. Advanced digital photography, equipped with technology able to provide a detailed evaluation of red skin components corresponding to vascular flare (erythema-directed digital photography), is a useful tool for evaluation of erythema in patients affected by inflammatory dermatoses. The aim of this study was to assess the efficacy and safety of a new cosmetic topical gel containing ciclopiroxolamine, lactoferrin, glycero-phosphoinositol (GPI) and Aloe vera, for the treatment of facial seborrheic dermatitis by clinical and advanced digital photography evaluation.

    A Novel Technique to Reduce Contrast Exposure During Subclavian Interventions.
    Vasc Endovascular Surg 2017 Feb 23;51(2):84-86. Epub 2017 Jan 23.
    1 Department of Cardiovascular Diseases, Mayo Clinic, Rochester, MN, USA.
    We describe a novel technique to minimize total body contrast exposure during endovascular angiography. A patient with severe renal impairment and history of contrast-induced nephropathy was referred for subclavian artery intervention. Angiography and intervention was performed via transfemoral access, while a transradial sheathless-guiding catheter was used to aspirate injected contrast/blood mix from the downstream axillary artery.

    Investigating the functional morphology of genitalia during copulation in the grasshopper Melanoplus rotundipennis (Scudder, 1878) via correlative microscopy.

    Department of Entomology, Texas A&M University, College Station, Texas.
    We investigated probable functions of the interacting genitalic components of a male and a female of the flightless grasshopper species Melanoplus rotundipennis (Scudder, 1878) (frozen rapidly during copulation) via correlative microscopy; in this case, by synergizing micro-computed tomography (micro-CT) with digital single lens reflex camera photography with focal stacking, and scanning electron microscopy. To assign probable functions, we combined imaging results with observations of live and museum specimens, and function hypotheses from previous studies, the majority of which focused on museum specimens with few investigating hypotheses in a physical framework of copulation. For both sexes, detailed descriptions are given for each of the observed genitalic and other reproductive system components, the majority of which are involved in copulation, and we assigned probable functions to these latter components.
