Lightweight YOLOv8 for tongue teeth marks and fissures detection based on C2f_DCNv3.

This paper propose a significantly enhanced YOLOv8 model specifically designed for detecting tongue fissures and teeth marks in Traditional Chinese Medicine (TCM) diagnostic images. By integrating the C2f_DCNv3 module, which incorporates Deformable Convolutions (DCN), replace the original C2f module, enabling the model to exhibit exceptional adaptability to intricate and irregular features, such as fine fissures and teeth marks. Furthermore, the introduction of the Squeeze-and-Excitation (SE) attention mechanism optimizes feature weighting, allowing the model to focus more accurately on key regions of the image, even in the presence of complex backgrounds.

Influence of Floral Strip Width on Spider and Carabid Beetle Communities in Maize Fields.

The study explored the impact of floral strip width on the spider and carabid beetle communities in maize fields over two years. Three widths of floral strips (2 m, 4 m, and 6 m) were compared with maize-only control strips to evaluate species diversity and distribution. The results showed significant differences in both spider and carabid populations between floral and control strips, with 4 m and 6 m widths consistently harboring higher biodiversity.

DENV-1 Infection of Macrophages Induces Pyroptosis and Causes Changes in MicroRNA Expression Profiles.

Background: Dengue virus (DENV) is the most widespread mosquito-borne virus, which can cause dengue fever with mild symptoms, or progress to fatal dengue hemorrhagic fever and dengue shock syndrome.

Dynamic control of RNA-DNA hybrid formation orchestrates DNA2 activation at stalled forks by RNAPII and DDX39A.

Stalled replication forks, susceptible to nucleolytic threats, necessitate protective mechanisms involving pivotal factors such as the tumor suppressors BRCA1 and BRCA2. Here, we demonstrate that, upon replication stress, RNA polymerase II (RNAPII) is recruited to stalled forks, actively promoting the transient formation of RNA-DNA hybrids. These hybrids act as safeguards, preventing premature engagement by the DNA2 nuclease and uncontrolled DNA2-mediated degradation of nascent DNA.

Diffusion limitations and monofunctional acidity of ZSM-5 molecular sieves affect the catalyst stability and aromatic yield in the reaction of methanol to aromatics (MTA). In this study, based on ZSM-5 nanosheets as parent molecular sieves, Zn-modified hollow ZSM-5 nanosheets were obtained after hydrothermal treatment by adding ZIF-8 or zinc nitrate as a source of Zn while treating with different types and concentrations of alkali solutions. The physical and chemical properties of the fabricated samples and their catalytic performance of methanol aromatization were systematically investigated by a combination of XRD, TEM, N adsorption-desorption, NH-TPD, Py-IR, Al MAS NMR, Si MAS NMR, XPS, and TG characterization analyses and MTA experimental evaluation.

LAZARUS 1 functions as a positive regulator of plant immunity and systemic acquired resistance.

Systemic acquired resistance (SAR) is activated by local infection and confers enhanced resistance against subsequent pathogen invasion. Salicylic acid (SA) and N-hydroxypipecolic acid (NHP) are two key signaling molecules in SAR and their levels accumulate during SAR activation. Two members of plant-specific Calmodulin-Binding Protein 60 (CBP60) transcription factor family, CBP60g and SARD1, regulate the expression of biosynthetic genes of SA and NHP.

Impaired processing of spatiotemporal visual attention engagement deficits in Chinese children with developmental dyslexia.

Emerging evidence suggests that visuospatial attention plays an important role in reading among Chinese children with dyslexia. Additionally, numerous studies have shown that Chinese children with dyslexia have deficits in their visuospatial attention orienting; however, the visual attention engagement deficits in Chinese children with dyslexia remain unclear. Therefore, we used a visual attention masking (AM) paradigm to characterize the spatiotemporal distribution of visual attention engagement in Chinese children with dyslexia.

A novel targeted anticancer drug delivery strategy: Cnidium officinale polysaccharide conjugated with carboxymethyl-5-fluorouracil and folic acid for ovarian cancer therapy.

To mitigate adverse reactions induced by 5-fluorouracil (5-FU), Cnidium officinale fraction 2 (F2) polysaccharides served as the macromolecular carrier, facilitating its reaction with carboxymethyl-5-fluorouracil (C-5-FU) for producing F2-C-5-FU. Subsequently, this compound could react with folic acid (FA) through the ester bond, forming F2-C-5-FU-FA, as verified through NMR analysis. The in vitro anticancer efficacy of F2-C-5-FU-FA was evaluated using SKOV-3 cells that expressed folate receptor (FR) and FR-deficient A549 cells, showing greater cytotoxicity in the SKOV-3 cell line due to the FRs on the cell membrane.
