Active travel (walking and cycling) is beneficial for people’s health and has many co-benefits, such as reducing motor vehicle congestion and pollution in urban areas. There have been few robust evaluations of active travel, and very few studies have valued health and emissions outcomes. The ACTIVE before-and-after quasi-experimental study estimated the net benefits of health and other outcomes from New Zealand’s Model Communities Programme using an empirical analysis comparing two intervention cities with two control cities...

Noble metal nanoparticles (NPs) such as Au, Ag have shown many applications in the field of catalysis and sensing etc due to their excellent photoelectric properties. But agglomeration and low recovery rate are big problems for their applications. In this research, a novel Ag NPs/graphene (reduced graphene oxide)-loading loofah sponge (Ag NPs/RGO-LS) was synthesized through a one-step reduction method. Where the RGO is used as a nano-support with the high specific surface area and the high conductivity to prevent the agglomeration of Ag NPs and provide a conductive layer...

BACKGROUND: There has been much interest in the transitions along the medical education continuum. However, little is known about how students from non-traditional backgrounds experience both the move to, and through Medical School, and their ambitions post-graduation. This research sought to understand the transitional journey into, and through undergraduate medical education, and future career aspirations for first-in-family (FiF) medical students. METHODS: Based on a interpretivist epistemological perspective, 20 FiF students from one English Medical School participated in semi-structured interviews...

Some amphibians occur in agricultural landscapes during certain periods of their life cycle and consequently might be exposed to plant protection products (PPPs). While the sensitivity of aquatic life-stages is considered to be covered by the standard assessment for aquatic organisms (especially fish), the situation is less clear for terrestrial amphibian life-stages. In this paper, considerations are presented on how a risk assessment for PPPs and terrestrial life-stages of amphibians could be conducted. It discusses available information concerning the toxicity of PPPs to terrestrial amphibians, and their potential exposure to PPPs in consideration of aspects of amphibian biology...

This paper presents a study on ground-level ozone (O3 ), nitrogen oxides (NOx  = NO + NO2 ) concentration and their variabilities in the ambient air of three sites of a tropical archipelago moderately urbanized. Statistical analysis were performed on quite complete (> 80%) five years of measurements (2008-2012). There are few studies on those pollutants and their seasonal behavior in the Caribbean area where pollution level and cities configuration are different from megacities. Analyses are focus on pollutant variations at the scale of the day, the week and the seasons using hourly data...

A 22-year-old man with spontaneous coronary artery dissection wanted to assess the feasibility of returning to competitive cycling. He was referred to the cardiac rehabilitation (CR) program at Baylor Hamilton Heart and Vascular Hospital where staff designed a high-intensity, sport-specific training program that simulated the movements and forces associated with his goal activity. The program was symptom limited and enabled the patient to train earlier and at a higher intensity than is typically allowed in conventional CR programs...

The golden jackal (Canis aureus) is a medium-sized canid species native to Europe. This species is characterized by rapid large-scale expansion. A similar trend is also observed in Serbia, where the species is now distributed in more than a half of the territory. Although jackals prefer habitats in human-dominated landscapes, these animals have not been studied well enough from an eco-epidemiological point of view, and little is known about their potential for carrying zoonotic pathogens. In a study conducted during a three-year period (01/2010-02/2013), a total of 216 hunted or road-killed golden jackals were collected from 10 localities in Serbia...

A meta-analysis has been conducted of the effects of bicycle helmets on serious head injury and other injuries among crash involved cyclists. 179 effect estimates from 55 studies from 1989-2017 are included in the meta-analysis. The use of bicycle helmets was found to reduce head injury by 48%, serious head injury by 60%, traumatic brain injury by 53%, face injury by 23%, and the total number of killed or seriously injured cyclists by 34%. Bicycle helmets were not found to have any statistically significant effect on cervical spine injury...

Cycling injury risk is an important topic, but few studies explore cycling risk in relation to exposure. This is largely because of a lack of exposure data, in other words how much cycling is done at different locations. This paper helps to fill this gap. It reports a case-control study of cycling injuries in London in 2013-2014, using modelled cyclist flow data alongside datasets covering some characteristics of the London route network. A multilevel binary logistic regression model is used to investigate factors associated with injury risk, comparing injury sites with control sites selected using the modelled flow data...

Consistent with a continuum approach to mental health, a growing body of research has established that paranoia occurs in the general population. The stress-vulnerability model would predict an association between environments high in threat and the presence of state paranoia, even in those with low dispositional trait paranoia. The present research examines whether urban cycling, a naturalistic environment high in interpersonal threat, is associated with state paranoia - operationalised as an explicit perception that other road users intend the agent harm...

Evolutionary success, as demonstrated by high abundance and a wide geographical range, is related to genetic variation and historical demography. Here we assess how climatic change during the Quaternary influenced the demography and distribution of the Neotropical swamp palm Mauritia flexuosa. Using microsatellite loci and coalescent analyses we examined how demographical dynamics affected genetic diversity, effective population size and connectivity through time and space. Mauritia flexuosa presents significant genetic differentiation between the Amazonian and Cerrado biomes and among different river basins...

OBJECTIVE: The objective of this study is to describe key risks related to dooring collisions on roads in mixed function activity centers by examining video footage recorded onboard the bicycles of cyclists riding through this road environment. The study aims to enhance our understanding of the risk associated with cyclist door collisions on these roads and to provide a focus for future studies that aim to identify measures that enhance cyclist safety. METHOD: The study measured 4 key risk exposures (per hour and kilometer), namely, on-street parked cars and 3 conditions associated with parked cars being accessed or egressed: door opened (a) after the cyclist passes (give-way event); (b) in the path of the cyclist without collision (obstruction event); and (c) in the path of the cyclist with collision (collision event)...

With increased regulations regarding the use of feed-grade antimicrobials in livestock systems, alternative strategies to enhance growth and immunity of feedlot cattle are warranted. Hence, this experiment compared performance, health and physiological responses of cattle supplemented with feed-grade antibiotics or alternative feed ingredients during the initial 60 days in the feedlot. Angus×Hereford calves (63 steers+42 heifers) originating from two cow-calf ranches were weaned on day -3, obtained from an auction yard on day -2 and road-transported (800 km; 12 h) to the feedlot...
