Purpose: Individual prognosis assessment is of paramount importance for treatment decision-making and active surveillance in cancer patients. We aimed to propose a radiomic model based on pre- and post-therapy MRI features for predicting disease-free survival (DFS) in locally advanced rectal cancer (LARC) following neoadjuvant chemoradiotherapy (nCRT) and subsequent surgical resection.

Methods: This retrospective study included a total of 126 LARC patients, which were randomly assigned to a training set (n = 84) and a validation set (n = 42).

GFH009 is a potent and highly selective cyclin-dependent kinase 9 (CDK9) inhibitor currently under phase II clinical trials. In this study, we investigated the metabolism and disposition of GFH009 in Sprague-Dawley (SD) rats, as well as metabolism of CD-1 mouse, SD rat, beagle dog, cynomolgus monkey, and human.A radiolabelled study indicated that [C]GFH009 was quickly and widely distributed throughout the body, but presented low levels in brain, testis, and epididymis after a single intravenous dose of 6 mg (100 µCi)/kg to SD rats.

Cyclin-dependent kinase 7 (CDK7) is a key regulator of the cell cycle and transcription, making it a promising target for cancer therapy. Although current CDK7 inhibitors have improved in their selectivity and druglike properties, CDK7 inhibitors have failed to progress through clinical development due to severe gastrointestinal and hematotoxic side effects. To mitigate these limitations, we have developed novel, macrocyclic, noncovalent CDK7 hit compounds and using a macrocyclization platform that has optimized these compounds from SY-5609, a leading clinical asset.

Article Synopsis
  • Accurate differentiation between non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC) is essential for surgical decisions, with the study focusing on optimizing T2-weighted MRI sequences for better assessments.
  • The researchers developed a multi-view fusion self-distillation (MVSD) model that uses both transverse and sagittal MRI views to improve classification of MIBC and NMIBC through enhanced feature extraction and integration of 3D information.
  • The MVSD model outperformed traditional deep learning methods and even surpassed the accuracy of two urologists, achieving a notable area under the curve (AUC) of 0.927 and an accuracy rate of 0.880, indicating strong potential for preoperative diagnosis of

  • Echinococcosis is a disease caused by parasites that mainly impact the liver, with high-risk areas in western China experiencing significant cases of hepatic echinococcosis and hepatic alveolar echinococcosis (HAE).
  • The World Health Organization recommends ultrasonography for initial screening, but there's a challenge in distinguishing between different types of liver lesions, including various types of echinococcosis.
  • This review advocates for using contrast-enhanced ultrasound to improve diagnostic accuracy and discusses imaging features to aid in early diagnosis and clinical decisions in regions where the disease is prevalent.

Grounded Situation Recognition (GSR) aims to generate structured image descriptions. For a given image, GSR needs to identify the key verb, the nouns corresponding to roles, and their bounding-box groundings. However, current GSR research demands numerous meticulously labeled images, which are labor-intensive and time-consuming, making it costly to expand detection categories.

It remains a challenge to effectively regulate the complicated microenvironment during the wound healing process. The optimization of synergistic action of angiogenesis and inflammation is considered critical for quicker scarless wound regeneration. Here, the silk nanofiber (SNF) acts as a multifunctional carrier to load hydrophobic asiaticoside (AC) and hydrophilic Mg, and also serves as an element to assemble injectable hydrogels, forming a bioactive matrix with improved angiogenic and anti-inflammatory capacities (SNF-AC-Mg).

  • Esophageal cancer (EC) is a serious health issue, and cancer-associated fibroblasts (CAFs) are potential targets for new therapies, particularly regarding how they interact with the tumor microenvironment.
  • The study identified and characterized MMP14 CAFs and their role in promoting cancer cell migration and reducing the effectiveness of CD8 T cells, which are crucial for tumor killing, especially in the context of PD-1 immunotherapy.
  • Exosomal tsRNA from MMP14 CAFs was found to inhibit CD8 T cell activity, specifically with tsRNA-10522, suggesting that these CAFs could serve as markers for predicting responses to PD-1 immunotherapy in esophageal cancer.

Design and synthesis of highly active and robust bifunctional cathode catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are of vital significance for practical applications of lithium-oxygen (Li-O) batteries. Herein, a built-in electric field (BIEF) strategy is reported to fabricate MnTe/MnO heterostructures with a large work function difference (ΔΦ) as a bifunctional cathode catalyst in Li-O batteries. The MnTe/MnO heterostructures with nanosheets and microporous structures result in an abundance of exposed active sites and facilitate mass transfer.

Owing to the dense extracellular matrix and high interstitial fluid pressure in the tumor microenvironment, methods which enhance the permeation and retention of nano drugs into liver tumors remain unsatisfactory for successful tumor treatment. We designed a near-infrared (NIR)- and ultrasound (US)-triggered Pt/Pd-engineered "cluster bomb" (Pt/Pd-CB) which actively penetrates liver cancer cell membranes and achieves photothermal and sonodynamic therapy (SDT). The physical forces generated by the fast expansion and collapse of perfluoropentane nanodroplets eject "sub bombs" (Pt/Pd nanoalloys) into liver cancer cells upon activation by NIR and US.
