The oceanic anoxic events (OAEs) are characterized by enhanced accumulation of organic matter in marine sediments. However, there is still an ongoing debate regarding the interplay between production and preservation during these events. Moreover, few studies provide quantitative estimations primary productivity and/or amount carbon preserved OAEs. Here, we used geochemical data from multiple w...

Abstract Oceanic Anoxic Event 2 (ca. 94 Ma; OAE2) was one of the largest Mesozoic carbon cycle perturbations, but associated emissions, primarily from Caribbean large igneous province (LIP) and marine burial fluxes, are poorly constrained. Here, we use box model LOSCAR-P to quantify role LIP volcanism enhanced organic (Corg) as constrained by magnitude shape positive stable isotope (δ13C) excur...

The aim was to investigate the effects of different frequencies treadmill exercise with total exercise time being constancy on articular cartilage, lipoxin A4 (LXA4) and the NF-κB pathway in rat model of monosodium iodoacetate-induced osteoarthritis (OA). Fifty male Sprague-Dawley rats were randomly divided into five groups (n = 10): controls (CG), knee OA model (OAG), OA + treadmill exercise o...
