The flower buds of three Panax species (PGF: bud P. ginseng; PQF: quinquefolius; PNF: notoginseng), widely consumed as healthcare products, are easily confused particularly in the extracts or traditional Chinese medicine (TCM) formulae. We aimed to develop an untargeted metabolomics approach, by ultra-high performance liquid chromatography/ion mobility-quadrupole time-of-flight mass spectrometry (UHPLC/IM-QTOF-MS) unveil chemical markers diagnostic for differentiation PGF, PQF, and PNF. Key...

Abstract Global warming during the Paleocene‐Eocene Thermal Maximum (PETM) ∼55.5 million years ago (Ma) was associated with a massive release of carbon to ocean‐atmosphere system, as evidenced by prominent negative isotope excursion (CIE) and widespread dissolution marine carbonates. The paleohydrologic response PETM has been studied worldwide; however, relevant records environmental perturbation in Asia are lacking so far. Here we extend record this event central China, subtropical...

The complexity of herbal matrix necessitates the development powerful analytical strategies to enable comprehensive multicomponent characterization. In this work, targeting multicomponents from Panax japonicus C.A. Meyer, both data dependent acquisition (DDA) and data-independent high-definition MSE (HDMSE) in negative electrospray ionization mode were used extend coverage untargeted metabolites characterization by ultra-high-performance liquid chromatography (UHPLC) coupled a VionTM IM-QTOF...

Magnetostratigraphic study of 251 horizons through the younger Yaha succession in Kuche Depression Tarim Basin, NW China, lying beneath a massive regionally extensive (Xiyu) conglomerate formation identifies nine reversed and eight normal polarity chrons correlating with Geomagnetic Polarity Time Scale to show that deposition spanned interval ∼5.3 ∼1.7 Ma. Sedimentation rates fell episodically from ∼49 ∼24 cm/kyr as neotectonic deformation southern Tian Shan thrust belt became focused on two...

Abstract Oceanic red beds, preserving primary depositional remanent magnetization, play a key role in reconstructing the Tethyan paleogeography. However, partial remagnetization caused by chemical processes could be pervasive these rocks, leading to flawed reconstructions, and thus, differentiating secondary remanences is important. In this paper, we conduct multiple X‐ray diffraction, petrographic, diffuse reflectance spectroscopy, rock magnetic analyses on Upper Cretaceous oceanic beds...

Polyphenols exhibit strong antioxidant, and anti-inflammatory but are limited by chemical instability low bioavailability. To address these challenges, we developed polyphenol-amino acid conjugates that self-assemble into stable nanospheres, enhancing their stability These nanoparticles demonstrate significantly improved ROS scavenging efficiency promote cell proliferation in vitro. The incorporation of amino acids enhances biocompatibility facilitates effective elimination. offer a...

To investigate the significance and relationship of glucose lipid metabolism, placental resistin, human carrier protein (LCN-2) expression in pregnant women with gestational diabetes mellitus (GDM) complicated by severe preeclampsia (SPE). A total 89 patients GDM SPE (G+S group) alone (GDM were included. Blood samples collected to measure metabolism indicators [fasting blood (FBG), fasting insulin (FINS), glycosylated hemoglobin (HbA1c), cholesterol (TC), triglycerides (TG), HDL-C, LDL-C],...

It is debated as to whether the modern-like East Asian monsoon formed during late Oligocene–early Miocene or Eocene. To resolve this dispute requires a comprehensive and updated synthesis of available geological records reliable modelling study. Here, we investigate Cenozoic climate patterns over Asia by compiling conducting for key periods based on our improved paleogeographies. Geological suggest that zonal (semi-)arid pattern was dominant tectonic timescales most Paleogene in...

As a crucial geological, climatic, and ecological boundary in the southeastern margin of Tibetan Plateau (SEMTP), topographic evolution Diancang Shan (DCS) remains unclear due to lack direct constraints on its paleoelevation. Here, we quantitatively reconstructed changes annual mean temperature (ANNT) based palynological data from terrestrial Dasongping section (∼ 7.6–1.8 Ma) Dali Basin, located at northeastern DCS Yunnan, China. Integrating thermochronological eastern...

The mid-Piacenzian (3.264–3.025 Ma) is regarded as being the most recent warm period with atmospheric CO2 levels comparable to those of present-day, thus reconstruction corresponding climate change provides a good reference for our understanding current and future global warming. In this study, we undertook reconstructions East Asia using modern analogue technique, based on fossil pollen records. results show significant spatial variations in paleoclimate, warmer zone northwest...
