AMPK down-regulating Beclin-1 in prostate cancer patients with bone metastasis: An observational study.

Bone metastasis is frequently seen in patients, particularly those with prostate cancer, showing a higher hazard that deteriorates the quality of life of patients, leading to poor prognosis, which eventually causes significant mortality in prostate cancer patients. The present study investigated the mechanism of prostate cancer with bone metastasis by utilizing prostate specimens from patients. A total of 418 patients were initially enrolled for clinical analysis, including age, prostate-specific antigen (PSA) levels, body mass index (BMI), prostate magnetic resonance imaging (MRI), and bone MRI, while pathological analysis included grade group and carcinoma of the prostate.

Raman Spectral Feature Enhancement Framework for Complex Multiclassification Tasks.

Cocktail strategy-based nanomedicine: A synergistic cascade of starvation, NIR-II photothermal, and gas therapy for enhanced tumor immunotherapy.

Immunotherapy has emerged as a highly promising strategy in the realm of cancer treatment, wherein immunogenic cell death (ICD) is considered a potential trigger for anti-tumor immunity by inducing adaptive immunity to dying cell antigens. This process is often accompanied by the exposure, active secretion, or passive release of a large number of damage-associated molecular patterns (DAMPs), which activate dendritic cells (DCs) and enhance their antigen-presenting capacity. Subsequently, it promotes the recruitment and activation of cytotoxic T lymphocytes, ultimately leading to tumor growth inhibition.

Development of a Nanobody-Alkaline Phosphatase Fusion Protein for Detection of SARS-CoV-2 Spike Protein in a Fluorescence Enzyme Immunoassay.

The continuous spread and evolution of severe acute respiratory symptom coronavirus 2 (SARS-CoV-2) necessitate the development of convenient and rapid detection methods. In this study, we developed a fluorescence enzyme immunoassay (FEIA) based on a nanobody (Nb)-alkaline phosphatase (ALP) fusion protein for detection of SARS-CoV-2 spike protein. The genetically modified anti-SARS-CoV-2 S-RBD Nb, Nb61, gene was fused with the ALP gene sequences via a flexible linker.

Comparison of multi-phase contrast-enhanced T1-weighted volumetric interpolated breath-hold examination and fat-suppressed T2-weighted combined with diffusion-weighted magnetic resonance imaging in anal fistula evaluation.

Accurate preoperative evaluation of the fistula's traits is essential for customizing surgical strategies, improving patient outcomes, and reducing the likelihood of the disease returning. This study aimed to evaluate the diagnostic accuracy of multi-phase contrast-enhanced fat-suppressed T1-weighted imaging using three-dimensional gradient echo sequence volumetric interpolated breath-hold examination (CE-FS-T1-3D-VIBE) and fat-suppressed T2-weighted imaging combined with diffusion-weighted imaging (FS-T2WI-DWI) sequence in delineating the characteristics of anal fistulas.

Single-point ultrasound-guided iliohypogastric-ilioinguinal-genitofemoral nerve block for inguinal hernia surgery in older adult patients: a randomized controlled trial.

Background: Ultrasound-guided nerve block can be used for perioperative analgesia and can potentially improve the course of recovery. Although iliohypogastric-ilioinguinal nerve block has been successfully used for inguinal hernia surgery, the poor blocking effect of intraoperative traction reflex remains a major drawback of this technique. The main objective of this study was to investigate the feasibility of single-point ultrasound-guided iliohypogastric-ilioinguinal-genitofemoral nerve (GFN) blockage for open anterior inguinal hernia repair in older adults.

Construction and validation of a novel prognostic model with palmitoylation-related genes for glioblastoma.

Background: Glioblastoma multiforme (GBM), the most prevalent and aggressive primary brain tumor, poses substantial challenges in both treatment and prognosis. Post-translational modifications, like palmitoylation, are known to have critical roles in the development and progression of glioma. Yet, the molecular mechanisms involved in palmitoylation and its prognostic significance in GBM are still not fully understood.

Recent advances in cell membrane-coated porphyrin-based nanoscale MOFs for enhanced photodynamic therapy.

Porphyrins-based nanoscale metal-organic frameworks (nMOFs) has been widely utilized to kills tumor cells by generating cytotoxic reactive oxygen species (ROS). However, porphyrin based nMOFs (por-nMOFs) still face challenges such as rapid immune clearance and weak tumor targeting. Researchers have discovered that using a top-down biomimetic strategy, where nMOFs are coated with cell membranes, can promote long blood circulation, evade the reticuloendothelial system, and improve cancer cell targeting, thereby significantly enhancing the photodynamic therapy (PDT) effect of nMOFs.

Enhanced Cross-stage-attention U-Net for esophageal target volume segmentation.

Purpose: The segmentation of target volume and organs at risk (OAR) was a significant part of radiotherapy. Specifically, determining the location and scale of the esophagus in simulated computed tomography images was difficult and time-consuming primarily due to its complex structure and low contrast with the surrounding tissues. In this study, an Enhanced Cross-stage-attention U-Net was proposed to solve the segmentation problem for the esophageal gross tumor volume (GTV) and clinical tumor volume (CTV) in CT images.
