Hypoxia upregulate TPM4 expression to strengthen epithelial-mesenchymal transition that promotes lymph node metastasis of papillary thyroid cancer.

Papillary thyroid cancer (PTC) exhibits a high propensity for lymph node metastasis (LNM), significantly impacting postoperative recurrence and patient prognosis. The hypoxic microenvironment critically drives tumor progression by promoting PTC dedifferentiation. Through integrated bioinformatics analysis combining weighted gene co-expression network analysis and machine learning approaches on TCGA data, we identified TPM4 as a key hypoxia-responsive gene in PTC and validated its association with LNM using GEO datasets.

Survival Benefit of Hepatectomy after Complete or Partial Response to Conversion Therapy in Unresectable Hepatocellular Carcinoma (GUIDANCE003): A Multicenter Study.

Introduction: Uncertainty exists regarding whether hepatectomy enhances the prognosis for initially unresectable hepatocellular carcinoma (HCC) that becomes resectable subsequent to conversion therapy. This study conducted a comparative analysis of survival rates between patients who underwent hepatectomy and those who did not, following complete or partial response to conversion therapy.

Methods: This retrospective study examined 300 patients with HCC who underwent hepatectomy following conversion therapy, along with 265 nonsurgical control subjects (215 receiving locoregional/systemic therapy and 50 under active surveillance) across 20 Chinese medical centers from 2019 to 2023.

Efficacy assessment of repeat iodine-131 treatment in patients with papillary thyroid carcinoma assessed as biochemical incomplete response.

Purpose: Although most patients with Papillary Thyroid Carcinoma (PTC) have a favorable prognosis, some continue to have elevated serum Thyroglobulin (Tg) levels after surgery and ¹³¹I treatment, classified as a Biochemical Incomplete Response (BIR). According to the 2015 American Thyroid Association (ATA) guidelines, 20% of these patients will develop a Structural Incomplete Response (SIR). Doctors often recommend ¹³¹I retreatment without imaging evidence, hoping for benefits.

Multicenter, retrospective GUIDANCE001 study comparing transarterial chemoembolization with or without tyrosine kinase and immune checkpoint inhibitors as conversion therapy to treat unresectable hepatocellular carcinoma: Survival benefit in intermediate or advanced, but not early, stages.

Background And Aims: Various conversion therapy options have become available to patients with unresectable HCC, but which conversion therapy is optimal for which type of patient is controversial. This study compared the efficacy and safety of TACE alone or combined with immune checkpoint and tyrosine kinase inhibitors.

Approach And Results: Data were retrospectively compared for patients with initially unresectable HCC who underwent conversion therapy consisting of TACE alone (n=459) or combined with immune checkpoint and tyrosine kinase inhibitors (n=343).

Human serum albumin microspheres synchronously loaded with ZIF-8 and triptolide (TP) for the treatment of intrahepatic cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver tumor and remains a fatal malignancy in most patients. Only 20% to 30% of patients can be treated with potentially curative surgical resection. Local therapies such as radioembolization and hepatic arterial perfusion may be a more effective treatment strategy.

Larval Feeding Habits of Five Firefly Species Across Aquatic, Semi-Aquatic, and Terrestrial Lineages.

While adult fireflies are terrestrial, their larvae inhabit various habitat types, and a lack of comprehensive research on the feeding habits of these larvae across different habitats has greatly impeded the development of artificial diets. Here, we tested 14 types of foods, primarily covering gastropods, vertebrates, and fruit, to survey feed for aquatic ( and ), semi-aquatic ( and sp.), and terrestrial () fireflies.

'Mito-Bomb': a novel mitochondria-targeting nanosystem for ferroptosis-boosted sonodynamic antitumor therapy.

Mitochondria play an important role in regulating tumor cell death and metabolism so that they can be potential therapeutic targets. Sonodynamic therapy (SDT) represents an attractive antitumor method that induces apoptosis by producing highly toxic reactive oxygen species (ROS). Mitochondria-targeting SDT can cause oxidative damage and improve the efficiency of tumor therapy.

Robust High-Throughput Phenotyping with Deep Segmentation Enabled by a Web-Based Annotator.

The abilities of plant biologists and breeders to characterize the genetic basis of physiological traits are limited by their abilities to obtain quantitative data representing precise details of trait variation, and particularly to collect this data at a high-throughput scale with low cost. Although deep learning methods have demonstrated unprecedented potential to automate plant phenotyping, these methods commonly rely on large training sets that can be time-consuming to generate. Intelligent algorithms have therefore been proposed to enhance the productivity of these annotations and reduce human efforts.
