Asthenospheric flow and lithospheric erosion driving the outward growth of the northeastern Tibetan Plateau.

The northeastern (NE) Tibetan Plateau is extruding eastward at a rapid rate (∼15 mm a), but the role of the upper mantle in this process remains unclear. Early-Miocene primary melilitites from the leading edge of the extruding plateau provide critical insights into the upper mantle dynamics. Geochemical and Sr-Nd-Pb-Os isotopic data, supported by experimental melt comparisons, reveal that these melilitites originate from a hybrid source of CO-bearing mantle source, probably dominated by peridotite and pyroxenite/wehrlite lithologies.

Leveraging multinational enterprises to reduce the escalating regional carbon inequality in China.

Multinational enterprises (MNEs) affect regional inequality as they exert substantial yet uneven economic and environmental effects. This study evaluates the impacts of MNEs on China's regional carbon emission inequality against value-added gains using an environmentally extended interprovincial input-output model that differentiates MNEs activities across China's provincial-level administrative divisions. We find that MNEs predominantly concentrated in developed coastal regions from 1997-2012, while less developed inland regions accounted for less than 30% of MNEs-generated value-added but over 50% of MNEs-related carbon emissions.

A comprehensive model combining radiomics and risk factors for predicting massive hemorrhage in cesarean scar pregnancy during dilatation and curettage.

Background: To develop a comprehensive model integrating MRI radiomics signatures and independent risk factors for predicting the risk of massive bleeding during dilatation and curettage(D&C) in patients with cesarean scar pregnancy (CSP).

Methods: CSP patients who underwent D&C were retrospectively reviewed. Intraoperative massive bleeding was defined as bleeding exceeding 200 ml based on surgical records.

Clinical investigation of fertility after uterine artery embolization combined with dilation and curettage(D&C) or D&C alone for cesarean scar pregnancies.

Objective: The aim of this study was to compare the reproductive outcomes of patients with cesarean scar pregnancies (CSP) following uterine artery embolization (UAE) and dilation and curettage (D&C) treatments, and to evaluate the impact of UAE on fertility.

Materials: and methods: A retrospective case-control study was conducted. Patients diagnosed with CSP between 2019 and 2021 were included in the study.

Effects of traditional Chinese medicine pyritum on orthodontic tooth movement in rats.

Introduction: The objective of this study was to investigate the effects of pyritum on tooth movement.

Methods: Thirty 9-week-old male Sprague Dawley rats were divided into 3 groups: control group, tooth movement + saline (TM+S) group, and tooth movement + pyritum (TM+P) group. The OTM model was established in both the TM+S group and the TM+P group.

The economy-employment-environmental health transfer and embedded inequities of China's capital metropolitan area: a mixed-methods study.

Background: Metropolitan areas have complex trade linkages internally and externally. This complexity stimulates the unequal spatial transfer of environmental health consequences, economy, and employment embodied in internal trade or trade with the outside regions, resulting in unequal exchange. Existing research has rarely discussed this issue at a refined scale, hindering targeted inequity alleviation policies.

China's domestic industry redistribution facilitates carbon emissions mitigation.

Industry redistribution is a common economic phenomenon that involves a dynamic configuration of the production location across a region, country, or the world. However, measurements of the associated pollutant emission effects have not been well conducted at the domestically regional level. Here, we calculate the CO emission changes induced by China's domestic inter-provincial industry redistribution during 2002-2017 using a counterfactual approach in the multi-regional input-output framework.

Micro-computed tomography evaluation of the effects of orthodontic force on immature maxillary first molars and alveolar bone mineral density of Sprague-Dawley rats.

Objective: To investigate changes in the immature teeth of Sprague-Dawley rats during orthodontic treatment and to explore the changes in the peri-radicular alveolar bone through micro-computed tomography (CT).

Methods: Twenty-five 26-day-old male Sprague-Dawley rats were included. The maxillary left first molar was moved mesially under a continuous force of 30 cN, and the right first molar served as the control.

Managing stakeholders' conflicts for water reallocation from agriculture to industry in the Heihe River Basin in Northwest China.

Along with the accelerating process of industrialization and urbanization, water reallocation from agriculture to industry will be an inevitable trend in most developing countries. In the inland river basin, inter-sectoral water transfer is likely to result in reallocation of water resources between upstream and downstream regions, and further triggers frictions and conflicts between regions. Designing effective policy measures to coordinate these conflicts among stakeholders is crucial for the successful implementation of water reallocation.

Understanding Beijing's water challenge: a decomposition analysis of changes in Beijing's water footprint between 1997 and 2007.

Beijing has been experiencing increasing water shortage alongside its astonishing economic growth over the past decades. This study conducts a quasi-dynamic input-output (IO) analysis to investigate changes in Beijing's water footprint (WF) and decompose the effects of contributing factors to the changes during 1997-2007. The analysis distinguishes "internal" and "external" WF to depict connections of Beijing's water use with outside.

Effect of Achyranthes bidentata polysaccharides on the expression of BCL-2 and bax in hepatic tissues after exhaustive exercise in rats.

This study aims to assess the effects of Achyranthes bidentata polysaccharides (ABPS) on the expression of bcl-2 and bax in hepatic tissues after exhaustive exercise in order to provide theoretical support for the application of ABPS in the field of sports nutrition. Thirty male Sprague-Dawley rats were randomized into three groups, each consisting of 10 rats: Normal control group (NCG), Exhausting exercises control group (EECG), ABPS treated group (ATG). ABPS were fed orally by gastric intubation to rats of ABPS treated group (ATG) once daily for 7 days.
