Introduction: This study aimed to investigate Flavivirus infection in birds captured in green areas of São Paulo.
Methods: Oropharyngeal swabs, cloacal swabs, and blood samples from 170 birds captured in two green areas in São Paulo, Brazil were subjected to real time-polymerase chain reaction (RT-qPCR) analysis of Flavivirus specific NS5 gene fragment.
Results: All samples were negative for the presence of viral ribonucleic acid (RNA).
Conclusions: Despite the negative results, Flavivirus surveillance must be performed regularly due to favorable ecological conditions for virus circulation and transmission among birds in these areas and their close proximity to humans.

Microbial traits are critical for carbon sequestration and degradation in terrestrial ecosystems. Yet, our understanding of the relationship between carbon metabolic strategies and genomic traits like genome size remains limited. To address this knowledge gap, we conducted a global-scale meta-analysis of 2650 genomes, integrated whole-genome sequencing data, and performed a continental-scale metagenomic field study.

Polysaccharides, found universally in all living-species, exhibit diverse biochemical structures and play crucial roles in microorganisms, animals, and plants to defend against pathogens, environmental stress and climate-changing. Microbial exopolysaccharides are essential for cell adhesion and stress resilience and using them has notable advantages over synthetic polysaccharides. Exopolysaccharides have versatile structures and physicochemical properties, used in food systems, therapeutics, cosmetics, agriculture, and polymer industries.

A panel of 21 international experts are formed by the Asia-Pacific Vitreo-retina Society to work out the consensus and guidelines on polypoidal choroidal vasculopathy (PCV). PCV is a common subtype of neovascular age-related macular degeneration and is more prevalent in Asian populations. Recent advancement in imaging technology allows greater understanding of the disease process of PCV.

The coal molecular structure in micro-areas plays a critical role in matrix thermal conduction and volatile generation during the pyrolysis of tar-rich coal. However, as a major maceral contributing to hydrocarbon generation, the molecular structures of different micro-areas in vitrinite show heterogeneity, which still lacks research. Micro-FTIR technology was used in this study to characterize the molecular structure in different micro-areas of tar-rich coal with varying tar yields.

As climate change and urbanization progress, the urban heat island issue will affect more people. Urban blue-green spaces can effectively mitigate the urban heat island effect, and their structure and morphology significantly impact the degree of mitigation. To identify the most effective blue-green space distribution for mitigating the heat island effect across different urban function zones (UFZ), we selected 14 landscape metrics of blue-green spaces in the main urban area of Nanjing.
