Abstract The use of polypropylene composites in various industrial fields has expanded considerably in recent years. A number of researches have been carried out to characterize the performance of polypropylene and its composites. However, the effects of ageing on the long-term behaviour of this thermoplastic are not well understood. The purpose of this study is to analyse the consequences of thermal degradation on the thermal and mechanical properties of three distinct materials: virgin Polypropylene (PP), virgin Polypropylene + talc (PP/talc), and virgin Polypropylene + Carbon Black (PP/CB) micro-composites. Specimens of these materials underwent exposure in an… More >

Abstract Climate change, driven by anthropogenic activities, profoundly impacts ecosystems worldwide, particularly aquatic environments. This review explores the multifaceted effects of climate change on the phytoremediation capabilities of aquatic plants, focusing on the physiological responses to key environmental factors such as temperature, carbone dioxide (CO₂) and ozone (O₃) levels, pH, salinity, and light intensity. As global temperatures rise, moderate increases can enhance photosynthesis and biomass production, boosting the plants’ ability to absorb and detoxify contaminants, such as metals, pharmaceuticals, and nutrients. However, extreme temperatures and salinity levels impose stress, disrupting metabolic processes and reducing phytoremediation efficiency. Elevated CO₂… More >

Abstract The multifaceted roles of MYB transcriptional regulators are pivotal in orchestrating the complex processes of secondary metabolism, stress tolerance mechanisms, and life cycle progression and development. This study extensively examined the JrMYB genes using whole genome and transcriptomic data, focusing on identifying putative MYB genes associated with fatty acid metabolism. 126 MYB genes were identified within the walnut genome, characterized by hydrophilic proteins spanning lengths ranging from 78 to 1890 base pairs. Analysis of cis-acting elements within the promoter regions of MYB genes revealed many elements linked to cell development, environmental stress, and phytohormones. Transcriptomic data was utilized… More > Graphic Abstract

Abstract Cadmium (Cd) has seriously affected the quality of traditional Chinese medicinal material Salvia miltiorrhiza in recent years, threatening human health. The physiological and metabolic profiles of S. miltiorrhiza in response to Cd stress have been revealed in previous studies. However, transcriptional and post-transcriptional regulation in response to different degrees of Cd (0, 25, 50, and 100 mg/kg) stress in S. miltiorrhiza remains unclear. Here, transcriptome atlas in S. miltiorrhiza under different degrees of Cd Stress was unveiled using RNA sequencing (RNA-seq). These results showed that the profiles of gene expression were different in the response to Cd treatment. Defense More >

Abstract This study assesses the effectiveness of using arbuscular mycorrhizal fungi (M) and compost applied alone or in combination (vs. conventional chemical fertilizer application (NPK)) on tomato resistance to vascular wilt caused by Verticillium dahliae. In this study, ten treatments were applied: (1) Control (2) M: Rhizophagus irregularis (3) C: Compost (4) MC: The combination of M and compost (5) NPK: conventional chemical fertilizer (6) V: plants infected with V. dahliae (7) MV: plants infected with a conidial suspension of V. dahliae and M, (8) CV: The combination of compost and V. dahliae, (9) MCV: The combination of M, compost and V. dahliae,… More >

Abstract Anoplophora glabripennis is one of the most devastating wood-boring beetles that attacks poplars. However, one poplar species, Populus deltoides, has strong resistance to Anoplophora glabripennis infestation, the underlying defense mechanisms against Anoplophora glabripennis are poorly understood. Secondary metabolites play a crucial role in plants to combat biological stress. Here, based on transcriptome and metabolome, we demonstrated that the mechanisms for responses to mechanical damage and insect infestation were different. The degree of reactions to adult groove production, larval incubation, and larval frass production was not identical. In addition, the potential genes with insect resistance activity were identified.

Abstract The interplay between mitochondria, epigenetics, and the microbiota is intricately linked to both health and disease. Within our cells, a complex molecular dance occurs, where these components intertwine in a mesmerizing ballet that plays a decisive role in our health. Mitochondria, beyond being energy powerhouses, modulate nuclear gene expression through messengers like reactive oxidative stress (ROS) and calcium. Epigenetics, acting as the molecular conductor, regulates the expression of both nuclear and mitochondrial genes through modifications like DNA methylation. The intestinal microbiota itself produces short-chain fatty acids (SCFAs) that influence mitochondrial activity. SCFA-induced epigenetic modifications, like… More >

Abstract Background: Alveolar macrophage pyroptosis exacerbates inflammatory lung diseases, and tanshinone IIA is known for its anti-inflammatory properties. Thus, understanding how tanshinone IIA affects alveolar macrophage pyroptosis is essential. Methods: NR8383 cells were exposed to lipopolysaccharide (LPS) and adenosine triphosphate (ATP). We assessed cell viability, pyroptosis, and the expression of triggering receptors expressed on myeloid cells 2 (TREM2), p-β-catenin, β-catenin, and pyroptosis-related factors. We also examined the interaction between tanshinone IIA and TREM2. Results: Co-stimulation with LPS and ATP significantly reduced NR8383 cell viability, increased pyroptosis, and upregulated pyroptosis-associated factors. Treatment with tanshinone IIA mitigated these effects.… More >

Abstract Background: Osteosarcoma is the most common primary bone malignancy, with a strong tendency towards local invasion and metastasis. The SRY-Box Transcription Factor 1 (SOX1) gene, a member of the HMG-box family of DNA-binding transcription factors, plays a crucial role in embryogenesis and tumorigenesis. However, its role in osteosarcoma, particularly in relation to metastatic potential, is not well understood. Methods: The GSE14359 dataset containing five samples of conventional osteosarcoma and four samples of lung metastatic osteosarcoma was obtained from the Gene Expression Omnibus (GEO) database and analyzed for differential gene expression using the R language.
