Insulin resistance, a major factor in the pathogenesis of type 2 diabetes mellitus, is due mostly to decreased stimulation glycogen synthesis muscle by insulin. The primary rate-controlling step responsible for decrease not known, although hexokinase activity and glucose transport have been implicated.
Abstract The latest Permian mass extinction, the most devastating biocrisis of Phanerozoic, has been widely attributed to eruptions Siberian Traps Large Igneous Province, although evidence a direct link scant date. Here, we measure mercury (Hg), assumed reflect shifts in volcanic activity, across Permian-Triassic boundary ten marine sections Northern Hemisphere. Hg concentration peaks close suggest coupling biotic extinction and increased activity. Additionally, isotopic data for subset...
Abstract Direct evidence of intense chemical weathering induced by volcanism is rare in sedimentary successions. Here, we undertake a multiproxy analysis (including organic carbon isotopes, mercury (Hg) concentrations and index alteration (CIA), clay minerals) two well-dated Triassic–Jurassic (T–J) boundary sections representing high- low/middle-paleolatitude sites. Both show increasing CIA association with Hg peaks near the T–J boundary. We interpret these results as reflecting...
Abstract The Siberian Traps large igneous province (STLIP) was the likely trigger for ca. 252 Ma latest Permian mass extinction (LPME), but direct evidence global volcanic effects on land remains rare. Here, we used mercury (Hg) enrichments, a proxy ancient activity, to assess inputs two terrestrial Permian-Triassic boundary (PTB) sections that were separated by thousands of kilometers and represent different latitudinal zones—the peri-equatorial Lubei section (South China craton)...
Abstract Enhanced regional subduction-related volcanism in the South China craton concurrent with Siberian Traps large igneous province magmatism was a likely contributor to major biotic and environmental stresses associated Permian-Triassic boundary (ca. 252 Ma) mass extinction. However, timing, intensity, duration of this volcanic activity remain uncertain. We analyzed mercury (Hg) concentrations three widely separated marine sections (Shangsi, Ganxi, Chaohu) as well Hg isotopic...
The sources of isotopically light carbon released during the end-Triassic mass extinction remain in debate. Here, we use mercury (Hg) concentrations and isotopes from a pelagic Triassic-Jurassic boundary section (Katsuyama, Japan) to track changes Hg cycling. Because its location central Panthalassa, far terrigenous runoff, enrichments at Katsuyama record atmospheric deposition. These are characterized by negative independent fractionation (MIF) odd isotopes, providing evidence their...
Abstract Reconstructing historical atmospheric oxygen (O 2 ) levels at finer temporal resolution is a top priority for exploring the evolution of life on Earth. This goal, however, challenged by gaps in traditionally employed sediment-hosted geochemical proxy data. Here, we propose an independent strategy—machine learning with global mafic igneous geochemistry big data to explore oxygenation over last 4.0 billion years. We observe overall two-step rise O similar published curves derived from...
Abstract The latest Permian mass extinction (LPME) was triggered by magmatism of the Siberian Traps Large Igneous Province (STLIP), which left an extensive record sedimentary Hg anomalies at Northern Hemisphere and tropical sites. Here, we present records from terrestrial sites in southern Pangea, nearly antipodal to contemporaneous STLIP activity, providing insights into global distribution volcanogenic during this event its environmental processing. These profiles (two Karoo Basin, South...
Theory regarding the causation of mass extinctions is in need systematization, which focus this contribution. Every extinction has both an ultimate cause, i.e. trigger that leads to various climato-environmental changes, and one or more proximate cause(s), specific changes result elevated biotic mortality. With regard causes, strong cases can be made bolide (i.e. meteor) impacts, large igneous province (LIP) eruptions bioevolutionary events have each triggered Phanerozoic Big Five...
The evolution of oxygen cycles on Earth’s surface has been regulated by the balance between molecular production and consumption. Neoproterozoic–Paleozoic transition likely marks second rise in atmospheric oceanic levels, widely attributed to enhanced burial organic carbon. However, it remains disputed how marine carbon respond global environmental changes whether these feedbacks trigger oxygenation during this interval. Here, we report a large lithium isotopic elemental dataset from...
The South China Craton experienced large changes in climate, eustasy and environmental conditions during the Late Ordovician Hirnantian Ice Age, but their impact on watermass architecture of Yangtze Sea has not yet been thoroughly evaluated. Here, we reconstruct salinity–redox structure based five Upper Ordovician–Lower Silurian shale successions representing a lateral transect from deep-water area Inner (IYS; Shuanghe section) across shallow Hunan–Hubei Arch (Pengye, Jiaoye Qiliao sections)...
Two Permian-Triassic boundary (PTB) sections from south China provide insights regarding the origin of negative excursions in carbonate and organic carbon isotope records associated with largest mass extinction Earth history. Xiakou, a ramp section, exhibits delta C-13(carb) up to -2 parts per thousand, Xinmin, deep-shelf C-13(org) -6 thousand. In both sections, these are volcanic ash layers, excursion size scales layer thickness. These relationships document direct influence volcanism on...
The Dongpan section in southern Guangxi Province records the influence of local volcanic activity on marine sedimentation at intermediate water depths (~200-500 m) Nanpanjiang Basin (South China) during late Permian crisis. We analyzed ~100 samples over a 12-m-thick interval, generating palynological, paleobiological, and geochemical datasets to investigate nature causes environmental changes. least two major episodes that culminated deposition approximately 25- 35-cm-thick ash layers...
