Abstract:
... Oxygen deficiency (hypoxia and anoxia) is an emerging concern in estuarine and coastal ecosystems worldwide. Previous studies on Mollusca Cephalopoda have focused on the effects of hypoxia stress on physiological performance and survival, but there are few reports on the molecular mechanism, and the application of metabolomics in cephalopods remains unknown. In this study, a ¹H nuclear magnetic re ...

Abstract:
... The colon ascendens stent peritonitis (CASP) surgery induces a leakage of gut contents, causing polymicrobial sepsis related to post-operative multiple organ failure and death in surgical patient. To evaluate the effects of CASP on multiple organs, we analyzed the systemic metabolic consequences in liver, kidney, lung, and heart of rats after CASP by employing a combination of metabolomics, clinic ...

Abstract:
... To identify potential biomarkers of salt stress in a freshwater sentinel species, we examined transcriptional responses of the common mussel Elliptio complanata to controlled sodium chloride (NaCl) exposures. Ribonucleic acid sequencing (RNA‐Seq) of mantle tissue identified 481 transcripts differentially expressed in adult mussels exposed to 2 ppt NaCl (1.2 ppt chloride) for 7 d, of which 290 had ...

Abstract:
... Ruditapes philippinarum, a clam that thrives in intertidal zones of various salinities, is a useful biomonitor to marine contaminants. We investigated the influence of dilution to 75% and 50% of normal seawater salinity (31.1) on the responses of the digestive gland of R. philippinarum to arsenic exposure (20 μg/L), using nuclear magnetic resonance (NMR)-based metabolomics. After acute arsenic exp ...

Abstract:
... CCl₄-induced metabonomic changes have been extensively studied for mammalian liver, and such changes have not been reported for other organs. To investigate the CCl₄ effects on other organs, we analyzed the CCl₄-induced metabonomic changes in rat kidney, lung, and spleen using ¹H NMR-based metabonomics approaches with complementary information on serum clinical chemistry and histopathology. We fou ...

Abstract:
... The release of the inhibitory amino acid taurine is markedly enhanced under ischemic conditions in both adult and developing brain stem, together with a pronounced increase in the release of the neuromodulator adenosine. We now studied the effects of adenosine receptor agonists and antagonists on [³H]taurine release in the brain stem in normoxia and ischemia, using a superfusion system. Under stan ...
