To answer these questions in light of the MRIO model, this paper presents a study of environmental injustice affecting the global economy. Practical ideas and lifespan measurements are often used in studies of the embodied carbon industry. The input-output table method is an important method for industrial embodied carbon research, which can be divided into the regional input-output table method, bilateral input-output table method, and multiregional input-output table method.

During spermiogenesis, the formation of the mitochondrial sheath is critical for male fertility. The molecular processes that govern the development of the mitochondrial sheath remain unknown. Whether TBC1D21 serves as a GTPase-activating protein (GAP) for GTP hydrolysis in the testis is unclear, despite recent findings indicating that it collaborates with numerous proteins to regulate the formation of the mitochondrial sheath.

Meiosis is essential for fertility in sexually reproducing species and this sophisticated process has been extensively studied. Notwithstanding these efforts, key factors involved in meiosis have not been fully characterized. In this study, we investigate the regulatory roles of zinc finger protein 541 (ZFP541) and its interacting protein potassium channel tetramerization domain containing 19 (KCTD19) in spermatogenesis.

BACKGROUND Endothelial cells are involved in vascular homeostasis, and endothelial cell dysfunction is involved in the pathogenesis of cardiovascular disease. This study aimed to investigate the effects of microRNA-154 in human umbilical vein endothelial cells (HUVECs) following injury induced by hydrogen peroxide (H₂O₂). MATERIAL AND METHODS Cell viability and apoptosis of HUVECs treated with H₂O₂ were measured.

BACKGROUND Carotid artery stenting (CAS) has been regarded as a reliable treatment approach for carotid artery stenosis. However, recurrent carotid artery stenosis after CAS affects long-term outcomes. In this study, we aimed to investigate the potential risk factors for carotid restenosis.

The modification of the mouse genome by site-specific gene insertion of transgenes and other genetic elements allows the study of gene function in different developmental stages and in the pathogenesis of diseases. Here, we generated a "genomic safe harbor" () locus-specific knock-in transgenic mouse line in which the promoter is used to drive the expression of the reverse tetracycline transactivator (rtTA) in the liver. The newly generated transgenic mice were bred with ) mice to assess inducibility and tissue-specificity.

Percutaneous coronary intervention (PCI) is main treatment for acute coronary syndrome (ACS). However, restenosis caused by PCI-induced injury influences the outcome of patients. Linagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, has been reported to ameliorate intimal hyperplasia post vascular injury.

Budd‑Chiari syndrome (BCS) is an uncommon disease characterized by the occlusion or obstruction of hepatic venous outflow. The mechanism of BCS is still unclear and there are no accurate and effective diagnostic or therapeutic tools. In the present study, blood samples from BCS patients and healthy controls were used for RNA‑sequencing.

Epigallocatechin-3-gallate (EGCG) is a kind of polyphenol compound, called catechin, and is extracted from green tea. EGCG has a wide range of biological activities. The present study aimed to evaluate the effect of EGCG on neointimal hyperplasia in a rat model of carotid artery balloon injury and to explore the molecular mechanisms involved.

Because of the bioactivity against the human topoisomerase II, the stereoisomeric impurities of sitafloxacin should be controlled in the process of manufactory. In the present work, a capillary electrophoresis (CE) method was developed and validated for simultaneous determination of three stereoisomeric impurities of sitafloxacin. The separation with high resolution not only for the separation of enantiomers, but also for the separation of diastereoisomers was achieved by using a background electrolyte composed of dual chiral selectors, namely γ-cyclodextrin (γ-CD) and Cu-d-phenylalanine (D-Phe) complex.

BACKGROUND There is little data comparing catheter-directed thrombolysis (CDT) via small saphenous veins vs. systematic thrombolysis on complications and efficacy in acute deep venous thrombosis patients. The aim of our study was to compare the efficacy and safety of CDT via the small saphenous veins with systematic thrombolysis for patients with acute deep venous thrombosis (DVT).

Article Synopsis
  • The study aimed to investigate the role of the Rho signaling pathway in the remodelling of periodontal tissue during tooth movement in rats.
  • Twenty-four male rats were split into groups, using a force to move teeth while monitoring changes in specific proteins (ROCK, LIMK, cofilin) over time through histological methods.
  • Results showed increased expression of these proteins on the tension side of teeth after applying force, indicating that Rho signaling plays a significant role in periodontal tissue changes during orthodontic treatment.
