Primary solitary fibrous tumor of the stomach: A case report and a review of literature.

Rationale: Solitary fibrous tumors (SFTs) are spindle cell tumors that typically occur in the pleura and peritoneum, but very rarely in the stomach. To our best knowledge, there are only 10 cases reported in English literature. We reported a case of primary stomach SFT and summarized the characteristics of all previous cases, suggesting that pathologists and surgeons should include this disease in the differential diagnosis list of primary mesenchymal tumor of the stomach.

Electromagnetic Wavefront Engineering by Switchable and Multifunctional Kirigami Metasurfaces.

Developing switchable and multifunctional metasurfaces is essential for high-integration photonics. However, most previous studies encountered challenges such as limited degrees of freedom, simple tuning of predefined functionality, and complicated control systems. Here, we develop a general strategy to construct switchable and multifunctional metasurfaces.

Maternal Exposure to Polystyrene Nanoplastics Disrupts Spermatogenesis in Mouse Offspring by Inducing Overexpression in Undifferentiated Spermatogonia.

Undifferentiated spermatogonia (Undiff-SPG) plays a critical role in maintaining continual spermatogenesis. However, the toxic effects and molecular mechanisms of maternal exposure to nanoplastics on offspring Undiff-SPG remain elusive. Here, we utilized a multiomics combined cytomorphological approach to explore the reproductive toxicity and mechanisms of polystyrene nanoplastics (PS-NPs) on offspring Undiff-SPG in mice after maternal exposure.

Development of a novel multi-epitope subunit mRNA vaccine candidate to combat Acinetobacter baumannii.

Acinetobacter baumannii, an opportunistic bacterium prevalent in various environment, is a significant cause of nosocomial infections in ICUs. As the causative agent of pneumonia, septicemia, and meningitis, A. baumannii typically exhibits multidrug resistance and is associated with poor prognosis, thus led to a challenge for researchers in developing new treatment and prevention methods.

Elevated methylmercury production in seasonally inundated sediments: Insights from DOM molecular composition.

Seasonally inundated areas (SIA) within aquatic systems are characterized by elevated methylmercury (MeHg) production. Nevertheless, the response characteristics of dissolved organic matter (DOM) quality in SIA sediments, including its molecular compositions and structure, and their impacts on the MeHg production are not yet fully understood. This research gap has been addressed through field investigations and microcosm experiments conducted in a metal-polluted plateau wetland.
