Objective: To study the correlation between expression levels of focal adhesion kinase (FAK) in oral squamous cell carcinoma (OSCC) and clinical prognosis with pathologic parameters.
Methods: Eighty paraffin embedded tissue specimens of OSCC were studied by immunohistochemistry. The data was analyzed by SPSS statistical software.
Results: FAK was highly expressed in OSCC tissues, in contrast to none or a low expression in normal oral epithelial tissue, and the heterogeneous staining was mainly located in the cell membrane and cytoplasm. FAK overexpression significantly correlated with histological differentiation and TNM stage, lymphatic metastasis. Multivariate analysis revealed that overexpression of FAK was the independent prognostic factor.
Conclusion: The overexpression of FAK in the peripheral area of OSCC may serve as a useful biological factor affecting prognosis.

The quantity of cable conductors is a crucial parameter in cable manufacturing, and accurately detecting the number of conductors can effectively promote the digital transformation of the cable manufacturing industry. Challenges such as high density, adhesion, and knife mark interference in cable conductor images make intelligent detection of conductor quantity particularly difficult. To address these challenges, this study proposes the YOLO-cable model, which is an improvement made upon the YOLOv10 model.

Objective: Intrahepatic cholangiocarcinoma (iCCA) is a highly lethal hepatobiliary malignancy with an increasing incidence annually. Extensive research has elucidated the existence of a reciprocal interaction between platelets and cancer cells, which promotes tumor proliferation and metastasis. This study aims to investigate the function and mechanism underlying iCCA progression driven by the interplay between platelets and tumor cells, aiming to provide novel therapeutic strategies for iCCA.

Long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript1 (MALAT1) has emerged as a crucial biomarker and therapeutic target for kidney diseases, including acute kidney injury (AKI), chronic kidney disease (CKD), diabetic kidney disease (DKD), lupus nephritis (LN), and renal cell carcinoma (RCC). LncRNAs are non-coding RNAs that have more than 200 nucleotides that play a crucial role in gene regulation at the post-translational stage, transcriptional, and epigenetic levels. LncRNA MALAT1 regulates gene expression and modulates cellular functions such as proliferation, inflammation, apoptosis, and fibrosis, which are key pathophysiology of kidney diseases.

The native extracellular matrix is continuously remodeled to form complex interconnected network structures that reversibly regulate stem cell behaviors. Both regulation and understanding of its intricate dynamicity can help to modulate numerous cell behaviors. However, neither of these has yet been achieved due to the lack of designing and modeling such complex structures with dynamic controllability.
