Ranunculales, comprising of 7 families that are rich in medicinal species frequently utilized by traditional medicine and ethnomedicine, represents a treasure chest of biodiversity and chemodiversity. The phylogenetically related species often have similar chemical profile, which makes them often possess similar therapeutic spectrum. This has been validated by both ethnomedicinal experiences and pharmacological investigations. This paper summarizes molecular phylogeny, chemical constituents, and therapeutic applications of Ranunculales, i.e., a pharmacophylogeny study of this representative medicinal order. The phytochemistry/metabolome, ethnomedicine and bioactivity/pharmacology data are incorporated within the phylogenetic framework of Ranunculales. The most studied compounds of this order include benzylisoquinoline alkaloid, flavonoid, terpenoid, saponin and lignan, etc. Bisbenzylisoquinoline alkaloids are especially abundant in Berberidaceae and Menispermaceae. The most frequent ethnomedicinal uses are arthritis, heat-clearing and detoxification, carbuncle-abscess and sore-toxin. The most studied bioactivities are anticancer/cytotoxic, antimicrobial, and anti-inflammatory activities, etc. The pharmacophylogeny analysis, integrated with both traditional and modern medicinal uses, agrees with the molecular phylogeny based on chloroplast and nuclear DNA sequences, in which Ranunculales is divided into Ranunculaceae, Berberidaceae, Menispermaceae, Lardizabalaceae, Circaeasteraceae, Papaveraceae, and Eupteleaceae families. Chemical constituents and therapeutic efficacy of each taxonomic group are reviewed and the underlying connection between phylogeny, chemodiversity and clinical uses is revealed, which facilitate the conservation and sustainable utilization of Ranunculales pharmaceutical resources, as well as developing novel plant-based pharmacotherapy.

The Tokyo 2020 Olympic and Paralympic Games provided a significant opportunity to consider global warming as an issue to be seriously addressed to run the safe and fair games in the era of climate change. As the global temperature continuously rises and extreme hot-weather events increase in frequency and intensity, the future summer Olympic and Paralympic games will need to deal with the heat by applying thorough and appropriate countermeasures. In the recent decades, many mitigation measures to protect athletes from heat have been rapidly discussed by the sports community, including countermeasures to hold games at times and places with moderate temperature and climatic risk assessments with Wet Bulb Globe Temperature (WBGT) during the games. However, the excessive heat conditions in the Tokyo 2020 Games affected not only athletes, but also all people concerned the events. While deliberate considerations by organizers had been given to mitigate extraordinary heat, the evaluations of these measures and epidemiological analyses of risk factors of patients must be further enhanced to develop efficient measures for the future. Therefore, we discussed the underlying climate-related problems of the summer Olympic and Paralympic Games in view of what we had experienced in the Tokyo 2020 Games. Facing with emerging global warming, future intervention against heat in the summer Olympic and Paralympic games will need to integrate systematic disease surveillance and evaluation of intervention with an effective combination with the approaches previously conducted. The Tokyo 2020 Games is a wake-up call to accelerate the public health measures towards the creeping global warming.

Aims: This study aims to assess the impact of anthropogenic activities on shrimp microbiome in a biodiverse mangrove forest ecosystem, along the Merbok River, Kedah, Malaysia. Methodology and results: To assess the impacts, a microbiome study of wild post larvae shrimps along the river was conducted as a health indicator of the shrimp hosts which in turn would reflect the river conditions. A 16S rRNA gene amplicon sequencing of the wild post larvae shrimp microbiomes sampled across areas of varying human activities was conducted. Samples were obtained from four sites ranging from upstream river habitat to downstream brackish water towards the marine coast. Individuals detected from the sequence were then counted and their relative abundance of bacterial diversity were compared. All abundances are up to 100% and the diversity indices were calculated using proportions of each species. The Operational Taxonomy Unit (OTUs) were obtained by using USEARCH and UPARSE software. Twenty-eight bacterium phyla were detected, dominated by phyla Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes at each site. Eighteen families were dominant at each site with Streptomycetaceae being the major abundant. At the genus level, the most abundant genera were Streptomyces sp., Mesorhizobium sp., Rhizobium sp., Bacillus sp. and Pseudomonas sp. Conclusion, significance and impact of study In general, the diversity of opportunistic and coliform bacteria was low. Thus, despite being exposed to various levels of human activities, the Merbok River and its mangrove surroundings still serve as a good spawning and nursery sites of shrimps and presumably other inhabitants.

Yeast are comprised of diverse single-cell fungal species including budding yeast Saccharomyces cerevisiae and various nonconventional yeasts. Budding yeast is well known as an important industrial microorganism, which has been widely applied in various fields, such as biopharmaceutical and health industry, food, light industry and biofuels production. In the recent years, various yeast strains from different ecological environments have been isolated and characterized. Novel species have been continuously identified, and strains with diverse physiological characteristics such as stress resistance and production of bioactive compounds were selected, which proved abundant biodiversity of natural yeast resources. Genome mining of yeast strains, as well as multi-omics analyses (transcriptome, proteome and metabolome, etc.) can reveal diverse genetic diversity for strain engineering. The genetic resources including genes encoding various enzymes and regulatory proteins, promoters, and other elements, can be employed for development of robust strains. In addition to exploration of yeast natural diversity, phenotypes that are more suitable for industrial applications can be obtained by generation of a variety of genetic diversity through mutagenesis, laboratory adaptation, metabolic engineering, and synthetic biology design. The optimized genetic elements can be used to efficiently improve strain performance. Exploration of yeast biodiversity and genetic diversity can be employed to build efficient cell factories and produce biological enzymes, vaccines, various natural products as well as other valuable products. In this review, progress on yeast diversity is summarized, and the future prospects on efficient development and utilization of yeast biodiversity are proposed. The methods and schemes described in this review also provide a reference for exploration of diversity of other industrial microorganisms and development of efficient strains.

Air pollution, climate change, and reduced biodiversity are major threats to human health with detrimental effects on a variety of chronic noncommunicable diseases in particular respiratory and cardiovascular diseases. The extent of air pollution both outdoor and indoor air pollution and climate change including global warming is increasing-to alarming proportions particularly in the developing world especially rapidly industrializing countries worldwide. In recent years, Asia has experienced rapid economic growth and a deteriorating environment and increase in allergic diseases to epidemic proportions. Air pollutant levels in many Asian countries especially in China and India are substantially higher than are those in developed countries. Moreover, industrial, traffic-related, and household biomass combustion, indoor pollutants from chemicals and tobacco are major sources of air pollutants, with increasing burden on respiratory allergies. Here we highlight the major components of outdoor and indoor air pollutants and their impacts on respiratory allergies associated with asthma and allergic rhinitis in the Asia-Pacific region. With Asia-Pacific comprising more than half of the world's population there is an urgent need to increase public awareness, highlight targets for interventions, public advocacy and a call to action to policy makers to implement policy changes towards reducing air pollution with interventions at a population-based level.

OBJECTIVE: To investigate changes in intestinal flora in patients with primary Sj?gren syndrome (pSS) and explore the relationship between pSS disease activity and intestinal flora structure. METHODS: Fecal samples were collected from 18 female pSS patients, including 9 patients with active disease (group A) and 9 with disease inactivity or low activity (group B), with 10 healthy subjects as the control group. The total bacterial DNA was extracted from the fecal samples for PCR amplification, and Illumina Hiseq 2500 high-throughput sequencing was performed for the v3-v4 region of 16Sr DNA gene to obtain the biological information of the intestinal flora. The intergroup OTU analysis, structural diversity analysis, significant difference analysis and LEFSE analysis were performed with information mining of the literature think tanks. RESULTS: The dilution curves generated based on the OTUshannon index for analysis of sample complexity showed that the measured data were relatively complete and could reflect the diversity of the microorganisms in the subjects. Analysis of the Alpha diversity index showed that the Shannon index differed significantly between group A and group B, and the Simpson index differed significantly between group A and group B and between group A and the control group ( < 0.05). Sequence analysis the 3 groups all consisted mainly of 4 phylum (, , , showed that the intestinal flora in and ) and 4 genera (, , , and ), all showing no significant differences among the 3 groups ( > 0.05) with the exception of genus, which differed significantly among the 3 groups ( < 0.05). The 16S v3-v4 region in the genus , , , , , , , , , , -, and differed significantly among the 3 groups ( < 0.05). The high-dimensional biometrics and genomic characteristics of the intestinal microorganisms differed significantly among the 3 groups ( < 0.05). According to the size of LDA SCORE (effect size), the core flora in group A included the genera , , -, , -, , , , and , as compared with the genera , , , , , -, , - and in the control group. CONCLUSIONS Patients with pSS have significant changes in the diversity of intestinal flora, especially in some specific bacteria in genus and in 16S v3-v4 region of the bacteria. The differences in the core bacteria in the intestinal flora of pSS patients suggest the role of flora structure changes in the pathogenesis of pSS.

It is of great significance to carry out scientific investigation of threatened species and assess their in-situ conservation status in order to guide the conservation and management of these species within a region. In this study, we explored and assessed the biodiversity and in-situ conservation status of the threatened medicinal vascular plants(TMVPs) in central China. The results showed that there were 276 TMVPs in central China, including 18 critically endangered(CR), 77 endangered(EN), and 181 vulnerable(VU) species. Of which, 222 TMVPs were distributed in 49 national nature reserves, with an in-situ conservation rate of 80.43%. And the in-situ conservation rate of CR, EN and NR species were 83.33%, 77.92% and 81.22%, respectively. The complementary algorithm was used to select the nine national nature reserves with the highest protection and complementary contribution to the TMVPs. The cumulative protection contribution rate of these nine nature reserves was 81.98%. Fifty-four TMVPs were distributed outside of national nature reserves, while mainly distributed within 10 hotspot counties including Badong county, Hubei province, Sangzhi county, Hunan province, Jianghua Yao Autonomous county, Hunan province and so on. In general, TMVPs are well protected by the national nature reserves in central China. However, there are still some conservation gaps. It is necessary to carry out further field investigation on the species with conservation gaps and identify the gap areas, so as to provide scientific guidance for the optimization of the conservation of TMVPs in this region.
