There is growing evidence that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) contaminates the marine environment and is bioaccumulated in filter-feeding shellfish. Previous study shows the Pacific oyster tissues can bioaccumulate the SARS-CoV-2, and the oyster heat shock protein 70 (oHSP70) may play as the primary attachment receptor to bind SARS-CoV-2's recombinant spike protein S1 subunit (rS1). However, detailed information about the interaction between rS1 and oHSP70 is still unknown. In this study, we confirmed that the affinity of recombinant oHSP70 (roHSP70) for rS1 (KD  = 20...

In the Solomon Islands and around the Pacific there is commonly a disconnect between government priorities for economic development through resource extraction and community aspirations for local resource management, conservation, and alternative pathways to livelihoods development, which includes tourism. Nowhere is this disconnect more stark than in communities on Rennell Island, within the region's oldest inscribed World Heritage area. These communities have so far resisted extractive industry development but have not yet benefited from inscription...

Uroteuthis edulis ( U. edulis ) is an important economic loliginid resource in the East China Sea (ECS). Its flexible life history traits enable the population to quickly adapt to changes in habitat. Understanding the early transport process helps us to grasp the habitat requirements of populations at key life history stages. In this study, particle tracing was used to simulate the early transport trajectories (within 120 days). The gradient forest method (GFM) and generalized additive mixed models (GAMMs) were used to analyze the key environmental variables that affect the early transport trajectories and the impact of environmental factors on the transport process, respectively...

Biological invasion is a primary direct driver of biodiversity loss. Recently, owing to exploitation competition with an invasive mussel, Mytella strigata (Hanley, 1843), there has been a drastic decrease in the population of native Perna viridis (Linnaeus, 1758) in several western Pacific regions. In the present study, intestinal microbiota, metabolome, and key digestive enzyme activities were compared between the two competing mussels, M. strigata and P. viridis , to elucidate the differences in intestinal microbiota and metabolic points...

BACKGROUND AND OBJECTIVES: Fermented foods play an important role in establishing intestinal bacterial flora, and the composition of the intestinal bacterial flora might be associated with neurodevelopment. This study investigated the association between maternal intake of fermented foods during pregnancy and early neuro-development in offspring. METHODS AND STUDY DESIGN: Data were analyzed for 73,522 pregnant women participating in the Japan Environment and Children's Study...

Food environment (FE), an interface where people interact with a broader food system, is critical to health. Understanding the Asian FE may help to tackle the "triple burden of malnutrition" through informed research and policy. This review identifies FE domains assessed in the Asian context and collates the tools/measures used in these evaluations. We further synthesized the reported associations of FE with diet and health outcomes and identified knowledge gaps. Forty-two articles were reviewed (East Asia, n = 25, 60%; South Asia, n = 8, 19%; and Southeast Asia, n = 9, 21%)...

Photosynthesis fuels primary production at the base of marine food webs. Yet, in many surface ocean ecosystems, diel-driven primary production is tightly coupled to daily loss. This tight coupling raises the question: which top-down drivers predominate in maintaining persistently stable picocyanobacterial populations over longer time scales? Motivated by high-frequency surface water measurements taken in the North Pacific Subtropical Gyre (NPSG), we developed multitrophic models to investigate bottom-up and top-down mechanisms underlying the balanced control of Prochlorococcus populations...

Worldwide climate-driven shifts in the distribution of species is of special concern when it involves habitat-forming species. In the coastal environment, large Laminarian algae-kelps-form key coastal ecosystems that support complex and diverse food webs. Among kelps, Macrocystis pyrifera is the most widely distributed habitat-forming species and provides essential ecosystem services. This study aimed to establish the main drivers of future distributional changes on a global scale and use them to predict future habitat suitability...

OBJECTIVE: The present systematic review explored compliance status with school food policies in Europe and the Western Pacific regions, challenges and facilitators of policy compliance, and its impact on children's diets and nutrient intakes. RESEARCH METHODS: An electronic search for full-text research articles published between January 2009 and July 2023 was conducted in Science Direct and PubMed scientific databases. RESULTS: A total of 659 titles and abstracts were screened, and final data was extracted from 34 included studies...

Ocean microorganisms constitute ~70% of the marine biomass, contribute to ~50% of the Earth's primary production, and play a vital role in global biogeochemical cycles. The marine heterotrophic and mixotrophic protistan and fungal communities have often been overlooked mainly due to limitations in morphological species identification. Despite the accumulation of studies on biogeographic patterns observed in microbial communities, our understanding of the abundance and distribution patterns within the microbial community of the largest subtropical gyre, the South Pacific Gyre (SPG), remains incomplete...

Within the broader Anthropocene Epoch resides the Plasticene Era, where humans are subjected pervasively to nano- and microplastics (NMPs). Human's widespread exposure with NMPs occurs through the air we breathe, water we drink, and food we eat. NMP sources are wide and varied; atmospheric NMPs are largely attributed to fibres from car tyres and synthetic clothing, while particles from food packaging, personal care products, and plastic manufacturing contribute significantly to food and water contamination...

OBJECTIVE: This study aimed to explore the perspectives of pediatric oncology clinicians in Thailand on children's gastrointestinal ​symptoms, eating habits, and nutrition during cancer chemotherapy. Additionally, it sought to identify factors influencing children's nutritional status, including the characteristics of the children, clinician-related factors, and hospital-level factors. METHODS: The study involved pediatric oncology clinicians working at a tertiary hospital in Bangkok...

BACKGROUND: Asthma is a heterogeneous disease with different outcomes. For children with asthma at the age of 7 years, 67-75% are symptom-free as adults. Data on the important link between childhood and adult asthma are sparse. OBJECTIVE: We aimed to investigate factors associated with persistence of childhood asthma over three years of follow-up by linking data between Korea childhood Asthma Study (KAS) and their matched claims data from Health Insurance Review and Assessment Service (HIRA)...

The Olympia oyster, Ostrea lurida, is the target of many restoration projects along estuaries on the North American Pacific coast, while the non-native Pacific oyster, Magallana gigas, dominates oyster aquaculture globally. Both species provide filtration functions that were investigated in three California bays using a whole-habitat, in situ approach, a laboratory particle selection experiment, and a regional physiological comparison. Measurements of chlorophyll α, temperature, salinity, and turbidity upstream and downstream, as well as point samples of seston total particulate matter and organic content to estimate habitat clearance rates (HCR, L hr-1  m-2 ) were collected...

Marine protists and their metabolic activities are intricately tied to the cycling of nutrients and the flow of energy through microbial food webs. Physiochemical changes in the environment, such as those that result from mesoscale eddies, may impact protistan communities, but the effects that such changes have on protists are poorly known. A metatranscriptomic study was conducted to investigate how eddies affected protists at adjacent cyclonic and anticyclonic eddy sites in the oligotrophic ocean at four depths from 25 to 250 m...

BACKGROUND: As a part of the decontamination process after the Fukushima Daiichi Nuclear Power Plant accident of 2011, 1.32 million tonnes of tritium-containing water will be discharged from the power plant into the Pacific Ocean. Although radiobiological impacts of the treated water discharge on the public and the environment were reported to be minimal, Tomioka and Okuma locals expressed unease regarding the long-term recovery of their towns, which are economically dependent on the agricultural, fishery, and tourism sectors...

BACKGROUND: Non-communicable diseases (NCDs) are a major threat to health and development and account for 75% of deaths in the Pacific Islands Countries and Territories (PICTs). Childhood obesity has been identified as a main risk factor for NCDs later in life. This review compiled overweight and obesity (OWOB) prevalence (anthropometric data) for children aged six to 12 years old living in the Pacific region and identified possible related causes. METHODS: We conducted a systematic search using PubMed, Google Scholar and ScienceDirect for articles published between January 1980 and August 2022...

The Chilean Patagonian fjords are globally renowned as one of the few remaining pristine environments on Earth; however, their ecosystems are under significant threat from climatic and anthropogenic pressures. Of particular concern is the lack of research into the impact of plastic pollution on the waters and biodiversity of these fjords. In this study, the marine environment of a secluded and sparsely populated fjord system in southern Patagonia was sampled to assess microplastics in seawater, beaches, bottom sediment, and zooplankton...

Microbial food webs (MFW) play an indispensable role in marine pelagic ecosystem, yet their composition and response to abiotic variables were poorly documented in the oligotrophic tropical Western Pacific. During winter of 2015, we conducted a survey to examine key components of MFW, including Synechococcus, Prochlorococcus, picoeukaryotes, heterotrophic prokaryotes (HP), heterotrophic/pigmented nanoflagellates and ciliates, across water column from surface to 2000 m. Each MFW component exhibited unique vertical distribution pattern, with abundance ratio varying over six and three orders of magnitude across Pico/Microplankton (1...
