EMGANet: Edge-Aware Multi-Scale Group-Mix Attention Network for Breast Cancer Ultrasound Image Segmentation.

Breast cancer is one of the most prevalent diseases for women worldwide. Early and accurate ultrasound image segmentation plays a crucial role in reducing mortality. Although deep learning methods have demonstrated remarkable segmentation potential, they still struggle with challenges in ultrasound images, including blurred boundaries and speckle noise.

MRRM: Advanced biomarker alignment in multi-staining pathology images via multi-scale ring rotation-invariant matching.

Pathology image matching is crucial for assisting pathologists in the comprehensive diagnosis of cancerous areas. However, variations in image rotation and staining caused by inherent slide imaging techniques increase the burden on pathologists, complicating the examination of cancer across different pathology slides. To address this challenge, we introduce multi-scale ring rotation-in variant matching (MRRM), which improves image matching efficiency using ring topology, assisting pathologists in robustly aligning biomarker information across various pathology images.

Chondroitin sulfate-based dissolvable microneedles loaded with NIR-II photothermal and natural anticancer agents for synergistic melanoma therapy.

Melanoma is characterized by its aggressiveness, high metastatic potential, and numerous mutations, which limit the effectiveness of current treatments. To address this issue, we developed a dissolvable microneedle (MN) system composed of poly(2-ethyl-2-oxazoline) (PEtOz) and chondroitin sulfate (CS). This MN system was loaded with liposomes containing both a NIR-II photothermal small molecule (IRLy) and the natural anticancer agent Gambogic acid (GA), forming Lip(IRLy + GA) MNs.

Highly-Efficient Differentiation of Reactive Lymphocytes in Peripheral Blood Using Multi-Object Detection Network With Large Kernels.

Reactive lymphocytes are an important type of leukocytes, which are morphologically transformed from lymphocytes. The increase in these cells is usually a sign of certain virus infections, so their detection plays an important role in the fight against diseases. Manual detection of reactive lymphocytes is undoubtedly time-consuming and labor-intensive, requiring a high level of professional knowledge.

Tellurium nanoparticles and Fucoidan-loaded dissolvable microneedles for combined photothermal therapy and anti-angiogenesis in melanoma treatment.

Melanoma, an aggressive skin tumor, is prone to metastasis, significantly reducing patient survival rates once it occurs. Tumor microvascularity is a key factor in metastasis, making the inhibition of microvascular formation crucial. Emerging photothermal therapy (PTT) and microneedles (MNs) have garnered attention due to their non-invasive and controllable nature.

Synergistic NIR and ultrasound-responsive tellurium nanorods for enhanced antibacterial and osteogenic activity.

Bacterial infections and deficient osteogenic activity are the primary factors contributing to the failure of orthopedic implants. In recent years, light- and sound-based external stimulus-responsive therapies have emerged as highly effective in killing drug-resistant bacteria. In this study, we successfully synthesized tellurium nanorods coated with bovine serum albumin (Te@BSA).

Rotor-based image-guided therapy of glioblastoma.

Glioblastoma (GBM), deep in the brain, is more challenging to diagnose and treat than other tumors. Such challenges have blocked the development of high-impact therapeutic approaches that combine reliable diagnosis with targeted therapy. Herein, effective cyanine dyes (IRLy) with the near-infrared two region (NIR-II) adsorption and aggregation-induced emission (AIE) have been developed via an "extended conjugation & molecular rotor" strategy for multimodal imaging and phototherapy of deep orthotopic GBM.

Amino-Functionalized Zirconium-Based Metal-Organic Frameworks as Bifunctional Nanomaterials to Treat Bone Tumors and Promote Osteogenesis.

Bone tumor patients often encounter challenges associated with cancer cell residues and bone defects postoperation. To address this, there is an urgent need to develop a material that can enable tumor treatment and promote bone repair. Metal-organic frameworks (MOFs) have attracted the interest of many researchers due to their special porous structure, which has great potential in regenerative medicine and drug delivery.

Zhi-Zi-Hou-Po decoction alleviates depressive-like behavior and promotes hippocampal neurogenesis in chronic unpredictable mild stress induced mice via activating the BDNF/TrkB/CREB pathway.

Ethnopharmacological Relevance: Zhi-Zi-Hou-Po decoction (ZZHP), a traditional Chinese medicine (TCM) classic recipe, has been extensively applied for the remedy of depression. However, the underlying mechanism of ZZHP hasn't been fully elucidated and it needs to be further clarified.

Aim Of Study: The aim of the study is to uncover the mechanisms of ZZHP's effect on depression.

Inhibiting Osteolytic Breast Cancer Bone Metastasis by Bone-Targeted Nanoagent via Remodeling the Bone Tumor Microenvironment Combined with NIR-II Photothermal Therapy.

Bone is one of the prone metastatic sites of patients with advanced breast cancer. The "vicious cycle" between osteoclasts and breast cancer cells plays an essential role in osteolytic bone metastasis from breast cancer. In order to inhibit bone metastasis from breast cancer, NIR-II photoresponsive bone-targeting nanosystems (CuP@PPy-ZOL NPs) are designed and synthesized.

Aggregation-Induced emission photosensitizer with lysosomal response for photodynamic therapy against cancer.

Photosensitizers play a key role in bioimaging and photodynamic therapy (PDT) of cancer. However, conventional photosensitizers usually do not achieve the desired efficacy in PDT due to their poor photostability, targeting ability, and responsiveness. Herein, we designed a series of photosensitizers with aggregation-induced emission (AIE) effect using benzothiazole- triphenylamine (BZT-triphenylamine) as the parent nucleus.

Bifunctional scaffolds for tumor therapy and bone regeneration: Synergistic effect and interplay between therapeutic agents and scaffold materials.

Bone tumor patients often face the problems with cancer cell residues and bone defects after the operation. Therefore, researchers have developed many bifunctional scaffolds with both tumor treatment and bone repair functions. Therapeutic agents are usually combined with bioactive scaffolds to achieve the "bifunctional".

A Facile and Universal Method for Preparing Polyethylene Glycol-Metal Hybrid Nanoparticles and Their Application in Tumor Theranostics.

Metal ions are of widespread interest owing to their brilliant biomedical functions. However, a simple and universal nanoplatform designed for assembling a range of functional metal ions has not been explored. In this study, a concept of polyethylene glycol (PEG)-mediated transport of metal ions is proposed.
