REVIEW
Chloe Bedard, Siying Sherry Liu, Christopher Patterson, Hertzel Gerstein, Lauren Griffith
AIMS: Diabetes puts many individuals at risk for developing diabetic retinopathy (DR). Non-mydriatic (NM) retinal photography without pharmacological pupil dilation can be used to detect DR, however, its value in a general clinical setting has not been established. The objective of this review is to evaluate the validity of NM retinal photos, as compared to the reference standard of seven standard stereoscopic 30 degree field photographs (7SF), for their use of detecting DR in community-dwelling adults...

BACKGROUND: Obstructive sleep apnea (OSA) is associated with changes in pharyngeal anatomy. The goal of this study was to objectively and reproducibly quantify pharyngeal anatomy using digital morphometrics based on a laser ruler, and to assess differences between apneics and controls and associations with AHI (apnea-hypopnea index). This is the first study to use digital morphometrics to quantify intraoral risk factors for OSA. METHODS: Digital photographs were obtained using an intraoral laser ruler and digital camera in 311 controls (mean AHI=4...

PURPOSE: Idiopathic macular telangiectasia type 2 (IMT2) is a bilateral acquired maculopathy, with a spectrum of clinical presentations associated with inner retinal telangiectatic vascular anomalies. Cases often are underdiagnosed or misdiagnosed. Current diagnostic modalities such as spectral-domain optical coherence tomography (SD-OCT) and fluorescein angiography (FA) are valuable to the understanding of the clinicopathology. More recently, optical coherence tomography angiography (OCTA), as an emerging noninvasive technology, has been shown to be particularly useful in the assessment and management of IMT2...

Since their first synthesis back in the early 20th century, 1,2,4-triazolo[1,5-a]pyrimidines have aroused increasing interest in very diverse areas ranging from chemotherapy to agriculture or even photography. Their similarity to purines confers a potential bioactivity and this feature has been wisely exploited for therapeutic use, including antifungal, antipyretic, analgesic, antiinflammatory, antitumoral and antiparasitic properties. In this review, we focus on the compounds that these nitrogen heterocycles form with metal ions and their antiparasitic activity and therapeutic potential against two neglected diseases of tropical prevalence, leishmaniasis and Chagas disease...

Prevention of fouling on surfaces is a major challenge that broadly impacts society. Water treatment technologies, hospital infrastructure, and seawater pipes exemplify surfaces that are susceptible to biofouling. Here we show that laser-induced graphene (LIG) printed on a polyimide film by irradiation with a CO2 infrared laser under ambient conditions is extremely biofilm resistant while as an electrode is strongly antibacterial. We investigated the antibacterial activity of the LIG surface using LIG powder in suspension or deposited on surfaces, and its activity depended on the particle size and oxygen content...

Presented here are observations of the outcomes of the collapses of large single bubbles in H_{2}O and D_{2}O at high ambient pressures. Experiments were carried out in a high-pressure spherical resonator at ambient pressures of up to 30 MPa and acoustic pressures up to 35 MPa. Monitoring of the collapse events and their outcomes was accomplished using multiframe high-speed photography. Among the observations to be presented are the temporal and spatial evolution of light emissions produced by the collapse events, which were observed to last on the order of 30 ns and have time independent radii on the order of 30μm; the production of Rayleigh-Taylor jets which were observed to travel distances of up to 70μm at speeds in excess of 4500 m/s; the entrainment of the light emitting regions in the jets' remnants; the production of spheroidal objects around the collapse points of the bubbles, far from any surface of the resonator; and the traversal and emergence of the Rayleigh-Taylor jets through the spherical objects...

Supramolecular hydrogel formed by the self-assembly of therapeutic agents have received considerable attention due to its high drug payload, carrier-free features. Herein, we constructed a dexamethasone sodium phosphate (Dex) supramolecular hydrogel in combination of Dex and calcium ion (Ca(2+)) and further demonstrated its therapeutic efficacy in the control of ocular inflammation. The developed supramolecular hydrogel was thoroughly characterized by rheology, TEM, FTIR and XRD. Calcium ions and Dex concentration had markedly influence on the sol-gel transition behavior of hydrogel and the proposed Dex supramolecular hydrogel displayed thixotropic property...

Alexander Gall
It is the central thesis of this paper that the "biological perspective" (Lynn Nyhart) typical for Germany, with its interest in living animals, not only influenced natural history practices in many ways during the second half of the 19th century, rather also shaped the illustrations of popular zoology publications, as for example those in Brehms Thierleben. The illustrators of this period preferred to use live animals as models, which they studied in zoos. These animals were often depicted in their "natural" habitats...
