BACKGROUND: Retinal detachment is an important cause of visual loss, but the association with outdoor heat exposure has not been studied. Our objective was to determine the relationship between acute exposure to high outdoor temperature and risk of retinal detachment. MATERIALS AND METHODS: We analysed 14,302 individuals with inpatient procedures for retinal detachment from April through September between 2006 and 2013 in the province of Quebec, Canada. Using a time-stratified case-crossover study design, we examined the association of retinal detachment with outdoor summer temperature the preceding week...

Wetlands in the region of Southern Ontario, Canada have declined substantially from their historic area. Existing regulations and programs have not abated this decline. However, reversing this trend by protecting or restoring wetlands will increase the supply of important ecosystem services. In particular, these actions will contribute to moderating the impacts of extreme weather predicted to result from climate change as well as reducing phosphorous loads in Lake Erie and ensuing eutrophication. Since the majority of land in the region is privately owned, landowners can play an important role...

Introduction: Despite smoker interest in e-cigarettes as a harm reduction or cessation aid, many smokers prematurely discontinue vaping after trying a product. This study explored the role of early subjective sensory experience in vaping persistence and desistence. Methods: African American menthol cigarette smokers aged ≥18 years (n=15; M=54.1 years; SD=8.2), motivated to quit smoking, and interested in trying e-cigarettes were recruited in Washington, D.C. Participants were followed for three weeks and provided menthol cigalike e-cigarettes after week one...

Purpose: It has been proposed that the peripheral retina, responding to local optical defocus, contributes to myopia and associated altered eye growth in humans. To test this hypothesis, we measured the changes in central (on-axis) and peripheral ocular dimensions in guinea pigs wearing a concentric bifocal spectacle lens design with power restricted to the periphery. Methods: Five groups of guinea pigs (n = 83) wore either a unifocal (UF) spectacle lens (-4, 0, or +4 Diopters [D]), or a peripheral defocus (PF) spectacle lens that had a plano center (diameter of 5 mm) with either -4 or +4 D in the surround (-4/0 or +4/0 D)...

Propofol (PFL, 1-hydroxyl-2,6-diisopropylbenzene) is currently used widely as one of the most well-known intravenous anesthetics to relieve surgical suffering, but its mechanism of action is not yet clear. Previous experimental studies have demonstrated that the hydroxyl group of PFL plays a dominant role in the molecular recognition of PFL with receptors that lead to hypnosis. To further explore the mechanism of anesthesia induced by PFL in the present work, the exact binding features and interaction details of PFL with three important proteins, human serum albumin (HSA), the pH-gated ion channel from Gloeobacter violaceus (GLIC) and horse spleen apoferritin (HSAF), were investigated systematically by using a rigorous three-layer ONIOM(M06-2X/6-31+G*:PM6:AMBER) method...

The regulation of RNA interference (RNAi) could be a powerful method for the study of temporal and dose dependent effects of gene expression. In this study, we designed the hepatitis delta virus (HDV) ribozyme with an embedded theophylline aptamer as the sensor domain and the pri-miRNA of endogenous gene Bcl-2 as the effector domain to engineer an RNAi-regulatory device in MCF-7 cells. The system allowed us to control gene expression by adding theophylline into the culture media in a dose dependent fashion...

Public health messages can be used to increase awareness about colorectal cancer screenings. Free or inexpensive images for creating health messages are readily available, yet little is known about how a pictured individual's engagement in the behavior of interest affects message outcomes. Participants ( N = 360), aged 50 to 75 years, completed an online survey in which they viewed a colorectal cancer screening message and were then randomly assigned to view one of four different messages about the pictured individual's screening status...

Feline leukemia virus (FeLV) is an oncogenic retrovirus of cats. Immunoassays for the p27 core protein of FeLV aid in the detection of FeLV infections. Commercial microtiter-plate ELISAs have rapid protocols and visual result interpretation, limiting their usefulness in high-throughput situations. The purpose of our study was to validate the PetChek FeLV 15 ELISA, which is designed for the reference laboratory, and incorporates sequential, orthogonal screening and confirmatory protocols. A cutoff for the screening assay was established with 100% accuracy using 309 feline samples (244 negative, 65 positive) defined by the combined results of FeLV PCR and an independent reference p27 antigen ELISA...

Despite extensive research in the international arena into pain and its management, there is, as yet, little research on the topic of pain in children in Saudi Arabia and in the Gulf countries generally. A systematic review was conducted to explore the impact of education programs on factors affecting paediatric nurses' postoperative pain management practice. This was done in order to advise the creation of an educational program for nurses in Saudi Arabia. Knowledge about pain, attitudes towards pain, beliefs about children's pain, perceptions of children's reports of pain, self-efficacy with regard to pain management, and perceptions of barriers to optimal practice were all considered to be relevant factors...

RNA-RNA assembly governs key biological processes and is a powerful tool for engineering synthetic genetic circuits. Characterizing RNA assembly in living cells often involves monitoring fluorescent reporter proteins, which are at best indirect measures of underlying RNA-RNA hybridization events and are subject to additional temporal and load constraints associated with translation and activation of reporter proteins. In contrast, RNA aptamers that sequester small molecule dyes and activate their fluorescence are increasingly utilized in genetically encoded strategies to report on RNA-level events...

Two important goals in orthopedic implants research are to promote osseointegration and prevent infection. However, much of previous efforts have been paid on the design of coatings either to enhance osseointegration while ignoring antibacterial activity or vice versa, to prevent infection while ignoring bone integration. Here, we designed a multifunctional mineralized collagen coating on titanium with the aid of metal-organic frameworks (MOFs) nanocrystals to control the release of naringin, a Chinese herbal medicine which could promote osseointegration and prevent bacterial infection...

REVIEW
Lauren Krumholz Marchette, John R Weisz
BACKGROUND: Psychotherapy for children and adolescents (herein, 'youths') has grown more precise and focused over the decades, shifting toward empirically supported treatments standardized via therapist manuals. The manuals have increasingly emphasized precise targeting of single disorders or problems, or homogenous clusters. These focal treatments represent a valuable advance, with intervention benefit documented in hundreds of studies. However, relatively few of these treatments are widely used in everyday clinical practice, and their level of benefit may not be ideal, particularly in practice contexts and when compared to usual clinical care...
