Human-induced climate change in Australia is affecting the frequency and intensity of extreme events, including bushfires, cyclones and drought. Human health is affected by these climate impacts through direct impacts which include injuries and death from extreme events; indirect impacts through natural system changes such as impacts on water, food and air; and indirect impacts on human systems including mental health, productivity, and damage to housing and health-care facilities. Remote settlements are vulnerable to these climate impacts and associated health impacts due to isolated location, quality of the infrastructure, economic resources, limited transport, and existing health vulnerabilities that enable resilience or vulnerability. Remote Indigenous communities are particularly vulnerable. This research sought to identify vulnerabilities of human health of residents in remote Indigenous communities to human-induced climate change to contribute to adequate responses of prevention and preparation.In recent years, people pay more and more attention to food quality and safety, which are significantly relating to human health. Food adulteration is a world-wide concerned issue relating to food quality and safety, and it is difficult to be detected. Modern detection techniques (high performance liquid chromatography, gas chromatography-mass spectrometer, etc.) can accurately identify the types and concentrations of adulterants in different food types. However, the characteristics as expensive, low efficient and complex sample preparation and operation limit the use of these techniques. The rapid, nondestructive and accurate detection techniques of food adulteration is of great and urgent demand. This paper introduced the principles, advantages and disadvantages of the nondestructive analysis techniques and reviewed the applications of these techniques in food adulteration screen in recent years. Differences among these techniques, differences on data interpretation and future prospects were also discussed.Recently, interest in smart packaging, which can show the color change of the packaging film according to the state of the food and evaluate the quality or freshness of the packaged food in real-time, is increasing. As a color indicator, a natural colorant, anthocyanin, drew a lot of attention due to their various colors as well as useful functions properties such as antioxidant activity and anti-carcinogenic and anti-inflammatory effects, prevention of cardiovascular disease, obesity, and diabetes. In particular, the pH-responsive color-changing function of anthocyanins is useful for making color indicator smart packaging films. This review addressed the latest information on the use of natural pigment anthocyanins for intelligent and active food packaging applications. Recent studies on eco-friendly biodegradable polymer-based color indicator films incorporated with anthocyanins have been addressed. Also, studies on the use of smart packaging films to monitor the freshness of foods such as milk, meat, and fish were reviewed. This review highlights the potential and challenges for the use of anthocyanins as pH-responsive color-changing films for intelligent food packaging applications, which may be beneficial for further development of smart color indicator films for practical use.Salmonella enterica serovar Pullorum (S. Pullorum) is an important pathogen specific to avian species, which poses a serious threat to the poultry industry. The transmission of S. Pullorum occurs both horizontally and vertically, but the airborne transmission of S. Pullorum has been neglected historically. In this study, the effects of aerosolized S. Pullorum were investigated on young chickens. The results showed that the colonization and morbidity induced by bioaerosol infection are dose dependent. The bacteria colonized in chicken lung for more than 14 days on exposure of ≥ 1.25 × 106 cfu/m3 of aerosolized S. Pullorum. Tachypnea and depression were present in all the chickens between 5-7 days after infection, and some died, on exposure of ≥ 1.25 × 108 cfu/m3 of aerosolized S. Pullorum. [https://www.selleckchem.com/products/srt2104-gsk2245840.html click here] RT-PCR results showed that significant expressions of inflammatory cytokines, including tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), IL-6 and IL-8 were noted in the lung and spleen. Histopathological examination showed lung swelling, with obvious lesions, including inflammatory cell infiltration, tissue injury, and acute hemorrhage. These results suggest that uncontrolled and detrimental inflammation is caused by high dose of aerosolized S. Pullorum. These results further extend our understanding of the pathogenicity of air-transmitted S. Pullorum on chickens. Research Highlights Aerosolized S. Pullorum caused tachypnea, depression and lung swelling of chicken; The colonization and morbidity caused by aerosolized S. Pullorum are dose dependent; Detrimental inflammation is caused by high doses of aerosolized S. Pullorum in lung.Vaccinations are critical to public health but uptake levels remain suboptimal. Intellectual humility, a virtue characterized by nonjudgmental recognition of one's own intellectual fallibility, may support the promotion of favorable vaccine attitudes. The current study investigated whether intellectual humility is related to anti-vaccination attitudes and intentions to vaccinate against the flu. Through an online survey management system, participants (N = 246, Mage = 39.06 years, SDage = 10.57, 50.80% female, 79.20% White, 6.50% Black/African American, 7.80% Asian, 1.20% Hispanic/Latino, and 5.30% Other) completed a measure for intellectual humility, the anti-vaccination attitudes (VAX) scale, and a three-item flu vaccine intention scale. We found that intellectual humility negatively correlated with anti-vaccination attitudes. This correlation was largely driven by openness to revising one's viewpoint and lack of intellectual overconfidence. Additionally, we found that intellectual humility did not relate to flu vaccination intentions. Finally, we discuss the implications of these findings and their potential to support the eventual development of strategies to leverage intellectual humility into a health promotion strategy.
