Panax ginseng is an important medicinal plant in China and is classified into two types: cultivated ginseng (CFCG) and mountain-cultivated ginseng (MCG). The two types of genetic varieties are the same, but the growth environments and management practices are different, resulting in substantial differences in their taproot morphology. Currently, there is a paucity of research on the internal mechanisms that regulate the phenotypic differences between cultivated ginseng and mountain-cultivated ginseng.

Objective: The emergence of multidrug-resistant (MDR) Escherichia coli strains has significantly constrained antibiotic treatment options, while the spread of antimicrobial resistance genes (ARGs) and mobile genetic elements exacerbates the situation. This study delves into an MDR E. coli strain, QMM-01, which uniquely co-expresses β-lactamases from all four recognized classes, aiming to uncover the underlying mechanisms of its resistance and assess its potential for global spread.

Background: Unwanted angiogenesis is involved in the progression of various malignant tumors and cardiovascular diseases, and the factors that regulate angiogenesis are potential therapeutic targets. We tested the hypothesis that DCBLD1 (discoidin, CUB, and LCCL domain-containing protein 1) is a coreceptor of VEGFR-2 (vascular endothelial growth factor receptor-2) and modulates angiogenesis in endothelial cells.

Methods: A carotid artery ligation model and retinal angiogenesis assay were used to study angiogenesis using globe knockout or endothelial cell-specific conditional knockout mice in vivo.

Cadmium (Cd) is a toxic heavy metal that poses a serious threat to crop safety and human health. Aspartate aminotransferase (AspAT) is a prime enzyme engaged in amino acid metabolism, contributing essential metabolic substances for plant growth and acclimatization to various stresses. In this study, we identified a novel AspAT9 gene with high responsiveness to Cd stress from poplar 'Nanlin895' and subsequently transformed it into Arabidopsis.

Ciprofloxacin (CIP) and gallium (Ga) are widely used in many fields and their excessive presences will pose serious threats to the environment and life health. Therefore, developing an intelligent detection method for rapidly tracking and determination of CIP and Ga⁺ concentration in environments and organisms is of great significance. In this work, a europium-doped carbon dots (Eu-CDs) with unique structure and performances was prepared by a one-pot hydrothermal method.

Article Synopsis
  • Ginseng, a medicinal plant, has two cultivation methods in China (under-forest and farmland), which affect its rhizome characteristics and economic value.
  • * A study transplanted two-year-old ginsengs into different habitats (farmland and forests) to examine how these environments influence rhizome morphology, revealing significant differences in growth due to light and soil nutrients.
  • * Findings showed rhizomes in forest settings were significantly longer and had changes in hormone levels and gene expression related to elongation, highlighting ginseng's ability to adapt morphologically to different habitats.

  • Hemoperfusion using the HA330/HA380 cartridge has become popular in ICUs over the last decade for treating critical illnesses by removing inflammatory substances from the blood.
  • While numerous studies indicate its potential benefits in reducing inflammation and organ failure, there is still no comprehensive assessment of its safety and effectiveness in critical care.
  • This paper aims to review the HA330/HA380 hemoperfusion technique, summarize recent clinical findings across various conditions, and highlight drug clearance capabilities to address safety issues.

Mesenchymal stem cells (MSCs) have been highly confirmed for their critical role in the treatment of different diseases. This study focuses on the mechanism of umbilical cord-derived MSCs (UC-MSCs) in the treatment of ornidazole (ORN)-induced asthenozoospermia (AS) in rats via the AKT/mTOR pathway. An animal model of AS was established in ORN-induced rats, followed by treatment of UC-MSCs and rapamycin (autophagy activator) or MK-2206 (AKT inhibitor).

Background: The interaction and combined effect of the triglyceride-glucose (TyG) index, an alternative parameter of insulin resistance, along with hypertension (HT), on the risk of peripheral arterial disease (PAD), a specific type of atherosclerotic cardiovascular disease, in individuals with type 2 diabetes (T2D) seems straightforward. However, specific research on this topic remains scarce.

Methods: In this cross-sectional study, 2027 adult participants with T2D were devided into four groups based on the mean values of TyG index and various blood pressure parameters along with its category.

Under the background of "dual carbon", the impact of the implementation of the Grain for Green project on the carbon storage of the ecosystem in the Yellow River Basin must be explored, which can serve as an important reference for improving the policy implementation of the new round of the Grain for Green project and improving the carbon sink capacity of the ecosystem in the Yellow River Basin. In this study, 1990, before the implementation of the project, was selected as the starting year of the research period, and 2020, after the implementation of the two rounds of the project, was selected as the end year of the research period. Based on the ecosystem type data from 1990 to 2020, the InVEST model was used to calculate the soil carbon pool, underground carbon pool, below carbon pool, dead organic matter carbon pool, and total carbon storage of ecosystems in the Yellow River Basin and the area where the project was implemented from 1990 to 2020.

Chemotherapy has been well shown to enhance life expectancy in patients with malignancy. However, conventional chemotherapy drugs, particularly cisplatin, are highly associated with nephrotoxicity, which limits therapeutic efficacy and impairs quality of life. Histone deacetylases (HDACs) are proteases that play significant roles in diseases by influencing protein post-translational modification and gene expression.

Aim: This study aimed to investigate the effects of low-dose dextran sulfate sodium (DSS) on the induction of chronic mild inflammation in mice and to evaluate the therapeutic potential of LRa05 (LRa05) to ameliorate the associated effects. The focus was on investigating changes in inflammatory, gut microbiota, serum lipopolysaccharide (LPS) and inflammatory cytokines.

Methods: Mice were exposed to a low-dose of DSS to induce chronic mild inflammation and LRa05 was administered as a probiotic intervention.

, a species within the genus , thrives optimally at 22-25°C but can also grow at the mammalian core body temperature of 37°C. This dual temperature adaptability necessitates establishing both temperature conditions in research to examine the effects on various biological processes. In quantitative real-time PCR (qRT-PCR) assays, the selection of appropriate housekeeping genes is vital for data accuracy.

Background: Mesenchymal stem cells (MSCs) have shown a positive effect on Osteoarthritis (OA), but the efficacy is still not significant in clinical. Conventional two-dimensional (2D) monolayer culture method is prone to cause MSCs undergoing replication senescence, which may affect the functions of MSCs. Three-dimensional (3D) culture strategy can sustain cell proliferative capacity and multi-differentiation potential.
