Pirfenidone is an anti-inflammatory and anti-fibrotic drug that has shown efficacy in lung and kidney fibrosis. Because inflammation and fibrosis have been linked to the progression of osteoarthritis, we investigated the effects of oral Pirfenidone in a mouse model of cartilage injury, which results in chronic inflammation and joint-wide fibrosis in mice that lack hyaluronan synthase 1 (Has1(-/-) ) in comparison to wild-type. Femoral cartilage was surgically injured in wild-type and Has1(-/-) mice, and Pirfenidone was administered in food starting after 3 days...

The inception and evolution of acoustic cavitation structures in thin liquid layers under different conditions and perturbations are investigated experimentally with high speed photography. The stability and characterization of cavitation structures are quantified by image analysis methods. It is found that cavitation structures (shape of bubble cloud and number of bubbles) are stable under unaltered experimental conditions, and the cavitation bubble cloud will return to the original structure and remain stable even in the face of large perturbations...

Early detection of skin cancer is essential to reducing morbidity and mortality from both melanoma and nonmelanoma skin cancers. Total-body skin examinations (TBSEs) may improve early detection of malignant melanomas (MMs) but are controversial due to the poor quality of data available to establish a mortality benefit from skin cancer screening. Total-body photography (TBP) promises to provide a way forward by lowering the costs of dermatologic screening while simultaneously leveraging technology to increase patient access to dermatologic care...

Since Oxford dictionary has described 'Selfie', selfie deaths have received a fair amount of coverage but the extent of the problem and the data behind it have not been appropriately explored. The aim of our study is to obtain epidemiological characteristics of selfie-related mortality worldwide with the objective of providing an insight to 'Why selfie', 'Why risky', 'Psychological basis' and 'measures of control.' Despite thousands of web pages, very few scientific articles are available in medical journals...

Medical photography, and in particular dermatological imagery, is often assumed to provide an objective, and functional, representation of disease and that it can act as a diagnostic aid. By contrast, artistic conceptions of the images of the body tend to focus on interpretative heterogeneity and ambiguity, aiming to create or explore meaning rather than enact a particular function. In her 2015 retrospective exhibition at the Tate Modern, South African artist Marlene Dumas questions these disciplinary divides by using medical imagery (among other photographic sources) as the basis for her portraits...

To ensure that elite adolescent athletes meet their unique training, growth and maturation demands, it is imperative to have access to valid measures of energy intake. Contemporary methods demand close attention-to-detail, meaning that athletes often do not fully adhere to real-time protocols. This study represents the first investigation of a real-time dietary assessment designed using a comprehensive behaviour change framework (COM-B). In a crossover design, 12 elite adolescent male rugby players recorded their energy intake via an estimated food diary (est-FD) and photography-based mobile assessment ('Snap-n-Send'), combined with a 24-h dietary recall interview...

Use of smartphone has become ubiquitous. With smartphone cameras becoming powerful, they are replacing digital cameras and digital SLRs as primary instruments to take photos and record videos. It is natural even for plastic surgeons that smartphones are handy to take still photographs and even record high-definition or 4K videos. Another invention which has become popular with smartphone photography is a selfie stick. We explain the possibility and methodology of using an iPhone and selfie stick to take operative photographs and high-quality videos...

BACKGROUND: Poor glycemic control in Type 1 Diabetes (T1D) patients is strongly associated with an increased risk of diabetes-related microvascular complications later in life, but it is unclear whether short period of poor glycemic control in children with T1D can cause evident microvascular morphological changes long before any pathological manifestation. Our study aimed to investigate the longitudinal association between poor glycemic control and subsequent changes in retinal microvasculature, in a pilot study of 55 pediatric T1D patients from Singapore after a one-year follow-up...

PURPOSE: Intralesional single low-dose vascular endothelial growth factor antagonists have traditionally failed in causing regression of pterygia. The current pilot study investigates the role of high-dose repeated intralesional ziv-aflibercept in causing regression of inflamed or recurring pterygia. METHODS: This prospective study from January 2015 to April 2017 consisted of using high dose of ziv-aflibercept between 0.1 mL (2.5 mg) and 0.3 mL (7.5 mg), depending on the pterygium size and the degree of inflammation...

Many creative ideas are being proposed for image sensor designs, and these may be useful in applications ranging from consumer photography to computer vision. To understand and evaluate each new design, we must create a corresponding image processing pipeline that transforms the sensor data into a form that is appropriate for the application. The need to design and optimize these pipelines is time-consuming and costly. We explain a method that combines machine learning and image systems simulation that automates the pipeline design...

Recently a correspondence in Zootaxa (Ceríaco et al., 2016) with more than 450 signatories including taxonomists, curators and other taxonomy users from all continents has received wide attention and has stimulated extensive discussion (a true buzz) around the possible interpretations of the Code (ICZN) about photography in taxonomy (Researchgate website link). This short note was necessary to recall the necessity of preserved specimens as vouchers for taxonomy, in response to photography-based taxonomy (PBT) as defended by Pape et al...

A recent series of papers, and rebuttals, regarding Photography-based taxonomy (PBT) (Pape et al. 2016, Krell et al. 2016, Ceríaco et al. 2016, Thorpe 2017) has raised much controversy and discussion about the practice of describing new species without preserved type specimens. Although there has been thoughtful discussion upon this issue, there is still much misunderstanding, especially regarding the idea of changing parts of the International Code of Zoological Nomenclature (ICZN 1999) to regulate this practice...

Recently, a new species of Diptera was described without preserving a type specimen (Evenhuis & Masrshall 2015). This publication caused controversy among taxonomists, of which many urged to restrict image-based descriptions to exceptional cases and insisted on the need to preserve specimens for future reproducibility of observations (Ceríaco et al. 2016; Krell 2016). I agree that type material is important in taxonomy for studying features that could not be captured on images. However, in the modern digital era, the need for actual specimen to study morphology can be circumvented...

PURPOSE: Direct ophthalmoscopy may be difficult without pupillary dilation and patient cooperation. Nonmydriatic ocular fundus photography (NMOFP) has been shown to be easily and efficiently accomplished by medical providers and improve the detection of abnormalities in adult emergency department (ED) patients. Nonmydriatic ocular fundus photography for pediatric ED patients has not been studied. The purpose of this study was to assess the ease of use of the Digital Retinography System (DRS) camera for NMOFP in ED patients aged 5 to 12 years and the quality of retinal images obtained with the DRS...

One of the most important and commonly encountered evidence types that can be recovered at crime scenes are biological fluids. Due to the ephemeral nature of biological fluids and the valuable DNA that they can contain, it is fundamental that these are documented extensively and recovered rapidly. Locating and identifying biological fluids can prove a challenging task but can aid in reconstructing a sequence of events. Alternate light sources (ALS) offer powerful non-invasive methods for locating and enhancing biological fluids utilising different wavelengths of light...

Aged skin is reported to be associated with unattractive skin color changes and solar elastosis. However, comparative studies have not documented the possible correlation between the two factors. This study investigated the plausible relationship between the facial skin color of elderly Asians and solar elastosis. A total of 22 skin specimens were collected from 22 Korean patients who underwent cheek skin biopsies. Skin color was quantitatively measured using colorimetric photography techniques to produce CIE L*a*b* values; the degree of solar elastosis was quantifiably assessed using a histologic grading scale...
