Transcriptomic analysis of the mechanism of male reproductive injuries caused by the mixture of three phthalates in rats.

Phthalates (PEs) are widespread in environment, and human beings are unavoidably exposing to the mixture of PEs, which may induce male reproductive health risks. In order to investigate the mechanism of male reproductive injuries caused by the mixture of di-2-ethylhexyl phthalate, dibutyl phthalate and butyl benzyl phthalate (MPEs), male rats were orally exposed to 16 mg/kg/d MPEs (L-MPEs) and 450 mg/kg/d MPEs (H-MPEs) for 90 days, and the results showed that MPEs decreased the weights of testes, epididymis and periepididymis fat, decreased serum levels of male hormones, increased abnormal sperm rate, and caused testicular histopathological damages, such as atrophy and cavitation of seminiferous tubules, spermatids exfoliation, Leydig cells hyperplasia and accumulation of lipid droplets in the testicular interstitium. Testicular transcriptomic analysis identified 100 differently expressed genes (DEGs) in L-MPEs group and 10,880 DEGs in H-MPEs group, and these DEGs mainly involved in signaling pathways of focal adhesion, PI3K-Akt, AGE-RAGE, axon guidance, PPAR, MAPK and etc.

Exploring Molecular Characteristics and Therapeutic Strategies for Primary Sinonasal Mucosal Melanoma with Distant Metastasis.

Sinonasal mucosal melanoma (SNMM) is a rare aggressive malignancy of the sinonasal tract. Due to its advanced clinical presentation and frequent late-stage diagnosis, the 5-year survival rate is less than 30%, with an even worse prognosis in patients with distant metastasis (SNMM-M). Therefore, characterizing the molecular landscape of SNMM may provide novel therapeutic targets for SNMM-M.

Optimizing multi-system coupling to mitigate carbon emissions in agrifood systems at county level in China.

The growing demand for food has led to overuse of land, exacerbating the environmental sustainability of agrifood systems. Insufficient coordination and coupling within agrifood systems (soil-crop-animal-food consumption) reduce material cycle efficiency and limit the system's carbon reduction potential. Given the lack of global research on the impact of system coupling on carbon reduction, the value of regional practice cases is particularly evident.

Here, we demonstrate how these pathways are modulated by specific hematite crystal facets. To investigate the influence of particle surface structure, methylene blue (MB) adsorption and photodegradation kinetics are examined using facet-engineered hematite nanoparticles with distinct exposed facets.

Calix[]azanediyldibenzoate: Intramolecular Hydrogen Bond-Assisted Synthesis, Acidichromism, and Oriented Self-Assembly.

Here, intramolecular hydrogen bond (IMHBs)-induced rigidity is used for the first time to synthesize macrocyclic arenes. Calix[]azanediyldibenzoates (C[]A, where = 3, 4, or 5) are synthesized through a one-step condensation reaction between dimethyl 2,2'-azanediyldibenzoate and paraformaldehyde. Compared to the monomer, the macrocycles exhibit a fast and significant acidochromic response due to the intramolecular charge transfer that is boosted by the synergistic effect of their adsorption and protonation.

MYC-Driven Activation of USP39 Enhances SRSF1 Stability and Promotes PDAC Progression.

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy primarily driven by oncogenic KRAS signaling. The splicing factor SRSF1 plays a key oncogenic role in PDAC, where its tightly regulated expression constrains KRAS-driven signaling under normal conditions, while its upregulation promotes tumorigenesis. SRSF1 expression is regulated in part by proteostasis.

Synthesis of three-dimensional nitrogen-doped reduced graphene oxide catalyst with high activity in acidic.

In this study, we synthesized a novel three-dimensional nitrogen-doped reduced graphene oxide (3D-NRGO) by integrating a sulfonated polystyrene (PSS) template method with nitrogen doping. The resulting 3D-NRGO was applied as an electrocatalyst for the oxygen reduction reaction (ORR) in acidic electrolyte. Owing to the synergistic effect arising from its three-dimensional structure and nitrogen doping, the catalyst demonstrates substantially augmented catalytic current density, a more positive ORR potential, excellent methanol tolerance, and prolonged operational stability.

Exercise Ameliorates Dopaminergic Neurodegeneration in Parkinson's Disease Mice by Suppressing Microglia-Regulated Neuroinflammation Through Irisin/AMPK/Sirt1 Pathway.

Although exercise is known to exert anti-inflammatory effects in neurodegenerative diseases, its specific impact and underlying mechanisms in Parkinson's disease (PD) remain poorly understood. This study explores the effects of exercise on microglia-mediated neuroinflammation and apoptosis in a PD model, focusing on the role of irisin signaling in mediating these effects. Using a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model, we found that a 10-week treadmill exercise regimen significantly enhanced motor function, reduced dopaminergic neuron loss, attenuated neuronal apoptosis, and alleviated neuroinflammation.

Unveiling the polarization switching pathway through tetragonal phase as a metastable intermediate state in ferroelectric HfZrO thin film.

The polarization switching pathway in HfZrO-based ferroelectric thin film is still not well clarified and agreed, limiting the fundamental physical understanding and performance engineering. The key question lies in clarifying the transient intermediate state during the polarization switching of orthorhombic phase. In this work, by designing the ferroelectric and dielectric stacks, we theoretically and experimentally demonstrate a polarization switching pathway through an orthorhombic-tetragonal-orthorhombic phase transition in ferroelectric HfZrO where the non-polar tetragonal phase is metastable.

A fusion ORF3a-E subgenomic RNA involved in SARS-CoV-2 infection efficacy by influencing cellular protein synthesis.

Subgenomic RNAs (sgRNAs) are discontinuous transcription products of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are involved in viral gene expression and replication, but their exact functions are still being studied. Here, we report the identification of a nested ORF3a-sgRNA, the fusion ORF3a-E-sgRNA, which is involved in the infection process of SARS-CoV-2. This sgRNA encodes both ORF3a and E and can be detected throughout the viral life cycle in SARS-CoV-2-infected cells with high copy numbers.
