Abstract:
... This essay contributes to work in media geography by bringing the geography of nostalgia into conversation with media nostalgia. Through an analysis of Amazon’s The Marvelous Mrs. Maisel’s text, intertextual discourses, location production, and tourism, I demonstrate how TV works to produce nostalgic attachments to places past, intervening materially into the present/future. Specifically, I argue ...

Abstract:
... Local governments are at the forefront of climate change adaptation planning. Although there is significant research on adaptation planning processes, there is scant empirical evidence of how local governments are completing the adaptation planning cycle by monitoring or evaluating their efforts. This leads to a fundamental lack of understanding about what actions work, in which contexts, and why? ...

Abstract:
... Vitamin A is a fat-soluble micronutrient necessary for the growth of healthy skin and hair. However, both too little and too much vitamin A has deleterious effects. Retinoic acid and retinal are the main active metabolites of vitamin A. Retinoic acid dose-dependently regulates hair follicle stem cells, influencing the functioning of the hair cycle, wound healing, and melanocyte stem cells. Retinoi ...

UL33 and US28 are also conserved with chemokine receptors: US28 binds numerous chemokine classes, including the membrane bound chemokine, fractalkine; whereas UL33 remains an orphan receptor. There is emerging data that UL33 and US28 each contri ...

Abstract:
... Plastic pollution is a pervasive and escalating global environmental problem, named among the most serious environmental issues globally, after climate change. A large percentage of the global plastic waste leakage is estimated to come from Asia, and most of this is from food and drink packaging. As a major user of single-use packaging, the food and beverage sector plays an important role in addre ...

... Vaccination is a cost-effective disease prevention measure. Sustainable financing is critical to successful implementation of vaccination programs. Countries in the Middle East and Africa (MEA) have vaccination programs that remain highly vulnerable to budget limitations. The objective of this study was to understand the current vaccine financing landscape in MEA; to assess the availability and va ...

Abstract:
... Probiotics are widely used in commercial shrimp aquaculture, but responses are variable. The objectives of this study were to quantitatively review using meta-analysis the production, survival, and immune responses of Macrobrachium rosenbergii to probiotics and to identify sources of residual variation. A total of 58 comparisons from 16 experiments (full text articles) were included in the final m ...

Abstract:
... The evolution of the bottom water in Amvrakikos Gulf in Ionian Sea at western Greece for a 50-year timespan was assessed by benthic foraminifera assemblages. The degradation of the bottom water of Amvrakikos has been a catalyst for the surface water degradation. The east basin has shown permanent low environmental quality in bottom waters since 1980, while the west basin has been under seasonal hy ...
