It has been predicted that the Arctic Ocean will sequester much greater amounts of carbon dioxide (CO2) from atmosphere as a result sea ice melt and increasing primary productivity. However, this prediction was made on basis observations either highly productive ocean margins or ice-covered basins before recent major retreat. We report here high-resolution survey sea-surface CO2 concentration across Canada Basin, showing great increase relative to earlier observations. Rapid invasion low...

The Arctic Ocean has experienced rapid warming and sea ice loss in recent decades, becoming the first open-ocean basin to experience widespread aragonite undersaturation [saturation state of (Ωarag) < 1]. However, its trend toward long-term ocean acidification underlying mechanisms remain undocumented. Here, we report there, with rates three four times higher than other basins, attribute it changing coverage on a decadal time scale. Sea melt exposes seawater atmosphere promotes uptake...

Multidrug resistance (MDR) is one of the major reasons chemotherapy-based treatments fail. Hypoxia generally associated with tumor chemoresistance. However, correlation between heterodimeric hypoxia-inducible factor-1 (HIF-1) and multidrug (MDR1) gene/transporter P-glycoprotein (P-gp) remains unclear. This study aims to explore molecular mechanisms reversing colon cancer MDR by focusing on target gene HIF-1α.A chemotherapeutic sensitivity assay was used observe efficiency reversal in LoVo...

Abstract During the summers of 2009 and 2013, seawater pH concentrations dissolved oxygen, inorganic carbon, nutrients were measured off Changjiang estuary in East China Sea. The cruise captured effects Typhoon Morakot; 2013 sampled more typical conditions (no typhoon). Data from both years indicate a close correlation between high primary productivity surface waters hypoxia bottom waters. Based on these observations, we developed conceptual model to guide an exploration processes...

Hypoxia off the Changjiang Estuary has been frequently reported using short time duration field data. However, its evolution was unknown because of a lack long-term data and associated dominant factor. A 104-day long dataset collected with bottom mounted system in summer 2009. The monitored parameters were dissolved oxygen (DO), temperature, pressure current. Two hypoxia events identified, showing that severe lasted for more than half month. first event appeared on July 18 17 days. During...

Achieving high energy density and long cycle life in alloy-type anodes remains a significant challenge due to the large volume changes during cycling. Here, we introduce high-entropy engineering approach using SnSb-based oxides codoped with Ti Al (SSBTA-600), designed promote formation of efficient oxygen vacancies at calcination temperature 600 °C. This results remarkable performance capacity 1012 mAh g-1 0.5 A 297 5 after 500 cycles, superior retention 99% 83.5%, respectively....

Cellular senescence is an important tumor-suppressive mechanism. However, acquisition of a senescence-associated secretory phenotype (SASP) in senescent cells has deleterious effects on the tissue microenvironment and, paradoxically, promotes tumor progression. In drug screen, we identified melatonin as novel SASP suppressor human cells. Strikingly, blunts global gene expression upon oncogene-induced (OIS). Moreover, poly(ADP-ribose) polymerase-1 (PARP-1), sensor DNA damage, was new...

Seamounts are ecological oases nurturing abundant fisheries resources and epibenthic megafauna in the vast oligotrophic ocean. Despite their significance, formation mechanisms underlying these seamount remain uncertain. To shed light on this phenomenon, study conducted interdisciplinary situ observations focusing a shallow The findings show that seamount's topography interferes with oceanic current to generate lee waves, effectively enhancing nutrient supply euphotic layer downstream of...
