Granulites from Huangtuling in the North Dabie metamorphic core complex in eastern China preserve rare mineralogical and mineral chemical evidence for multistage metamorphism related to Paleoproterozoic metamorphic processes,Triassic continental subduction-collision and Cretaceous collapse of the Dabie *** stages of metamorphism are resolved,based on detailed mineralogical and petrological studies:(Ⅰ) amphibolite facies(6.3-7.0 kbar,520-550℃);(Ⅱ) high-pressure/high-temperature granulite facies(12-15.5 kbar,920-980℃);(Ⅲ) cooling and decompression(4.8-6.0 kbar,630-700℃);(Ⅳ) medium-pressure granulite facies(7.7-9.0 kbar, 690-790℃);(Ⅴ) low-pressure/high-temperature granulite facies(4.0-4.7 kbar,860-920℃);(Ⅵ) retrograde greenschist facies overprint(1-2 kbar,340-370℃). The P-T history derived in this study and existing geochronological data indicate that the Huangtuling granulite records two cycles of orogenic crustal thickening *** earlier three stages of metamorphism define a clockwise P-T path,implying crustal thickening and thinning events,possibly related to the assembly and breakup of the Columbia Supercontinent ca.2000 Ma. StageⅣmetamorphism indicates another crustal thickening event,which is attributed to Triassic subduction/collision between the Yangtze and Sino-Korean *** dry lower crustal granulite persisted metastably during the Triassic subduction/collision due to lack of hydrous fluid and *** V metamorphism records the Cretaceous collapse of the Dabie Orogen, possibly due to asthenosphere upwelling or removal of the lithospheric mantle resulting in heating of the granulite and partial melting of the North Dabie metamorphic core *** of the Huangtuling granulite in North Dabie and the high-pressure(HP)-ultrahigh-pressure(UHP) metamorphic rocks in South Dabie indicates that the subducted upper(South Dabie) and lower (North Dabie) continental crusts underwent contrasting tectonometamorphic evolution during conti

Background-Occupational medicamentosa-like dermatitis induced by trichloroethylene(OMLDT) is an autoimmune disease and it has become a serious occupational health *** aim of this study was to develop potential serum biomarkers for OMLDT using a fast and efficient method of high-performance liquid chromatography(HPLC) coupled to MALDI-TOF/TOF-MS. Methods-We collected fasting blood samples from patients with OMLDT(n = 18) and healthy volunteers(n = 33) to explore serum peptidome *** proteins were purified with magnetic bead-based weak cation exchange chromatography and analyzed with *** and supervised neural network(SNN) algorithms were used on the training and testing data sets to establish classification *** protein/peptide peaks were identified by high mass accuracy measurements combined with top-down tandem mass spectrometry. Results-Thirty protein/peptide peaks were significantly different between the two groups and were selected as potential biomarkers of OMLDT *** SNN algorithm utilized three peaks(m/z 2106.3,2134.5,and 3263.67 Da) to separate the OMLDT patients from the healthy controls,with a cross validation of 94.44%and a recognition capability of 100%.The test sensitivity was 95.5%,and the test specificity was 73.8%.HPLC-TOF/TOF-MS identified two proteins that may play a role in the pathology of OMLDT:ATP-binding cassette transporter,and a fragment of albumin. Conclusion-Specific proteomic fingerprints in the sera of OMLDT patients could be used to identify OMLDT cases with high specificity and *** HPLC-TOF/TOF-MS approach will be of great value for exploring potential biomarkers and clinical studies of OMLDT.
