Background: Hyperuricemia (HUA) is a condition characterized by excessive uric acid production and/or inadequate uric acid excretion due to abnormal purine metabolism in the human body. Uric acid deposits resulting from HUA can lead to complications such as renal damage. Currently, drugs used to treat HUA lack specificity and often come with specific toxic side effects.

Cardiomyocyte proliferation in adult Xenopus tropicalis during heart regeneration has remained largely contentious due to the absence of genetic evidence. Here, we generated a transgenic reporter line Tg(mlc2:H2C) expressing mCherry specifically in cardiomyocyte nuclei driven by the promoter of myosin light chain 2 (mlc2). Using the reporter line, we found that traditional whole-cell staining is not a rigorous way to identify cardiomyocytes in adult Xenopus tropicalis when using a cryosection with common thickness (5 μm) which leading to a high error, but this deviation could be reduced by increasing section thickness.

Article Synopsis
  • An increasing number of nasopharyngeal carcinoma (NPC) patients are benefiting from a combination of immunotherapy and chemotherapy, but there's a lack of reliable methods to assess the treatment's effectiveness.
  • Researchers aimed to create a predictive model for the success of a PD-1 inhibitor and gemcitabine/cisplatin (GP) chemotherapy regimen using advanced imaging techniques and deep learning features.
  • The best-performing model, Tf_Radiomics+Resnet101, showed high accuracy in predicting treatment responses, potentially improving patient management in advanced NPC cases.

Thermometric techniques with high accuracy, fast response and ease of implementation are desirable for the study of dynamic combustion environments, transient reacting flows, and non-equilibrium plasmas. Herein, single-shot single-beam coherent Raman scattering (SS-CRS) thermometry is developed, for the first time to our knowledge, by using air lasing as a probe. We show that the air-lasing-assisted CRS signal has a high signal-to-noise ratio enabling single-shot measurements at a 1 kHz repetition rate.

Article Synopsis
  • Hepatitis B virus (HBV) infection is a significant global health issue, and current antiviral treatments face challenges, making targeting the HBx protein a potential solution for developing new therapies.
  • A study utilized the Nano-Glo HiBiT Lysis Detection System to screen for herbal compounds that inhibit HBx, with asiatic acid from Centella asiatica showing promising results in reducing HBx levels and HBV activity in infected cells and mice.
  • Findings suggest that asiatic acid works by promoting HBx degradation through autophagy, leading to decreased HBV transcription and establishing it as a potential anti-HBV treatment.

Objective: Long-chain fatty acid oxidation disorders (LC-FAOD) are a group of rare genetic inborn errors of metabolism. Clinical manifestations may result in frequent healthcare visits, hospitalizations, and early death. This retrospective cohort study assessed manifestations, healthcare resource use (HRU), direct medical costs, and the impact of COVID-19 on HRU among patients with LC-FAOD.

Surveillance recommendations for gastric cancer (GC) in current guidelines focused on advanced precancerous lesions and were based on precise diagnosis of severity/extent of baseline lesions. We aimed to develop a less endoscopy-related equipment-dependent risk-stratification tool, and assessed whether mild-precursor-lesion patients can be safely exempt from surveillance. In the multicenter community-based cohort, 75,051 participants receiving baseline endoscopy were enrolled during 2015-2017 and followed-up until 2021.

Background: Liver cancer remains the sixth most commonly diagnosed cancer and the third leading cause of cancer-related deaths worldwide, causing a heavy burden globally. An updated assessment of the global epidemiology of the liver cancer burden that addresses geographical disparities is necessary to better understand and promote healthcare delivery.

Methods: Data were extracted from the GLOBOCAN 2022 database, including the number, crude, and age-standardized rates of incidence and mortality at the global, country, continent, and human development index (HDI) regional levels.

Article Synopsis
  • Rosmarinic acid (RA) shows promise as a treatment for radiation-induced pulmonary fibrosis (RIPF) in mice, potentially reducing lung tissue damage after radiation therapy.
  • The study utilized various techniques, including mRNA sequencing and Western blotting, to reveal that RA inhibits fibroblast-to-myofibroblast transformation (FMT) by affecting exosomal signals from lung epithelial cells and altering tRNA modifications.
  • The mechanism involves RA decreasing the efficiency of sphingosine kinase 1 in lung fibroblasts, reducing PFKFB3 acetylation, and ultimately slowing down the glycolytic processes that contribute to RIPF.

Cancer is a major public health problem and represents substantial disparities worldwide. This study reported estimates for 36 cancers across 185 countries by incidence, mortality, 5-year prevalence, mortality-to-prevalence ratio (MPR), and mortality-to-incidence ratio (MIR) to examine its association with human development index (HDI) and gross national income (GNI). Data were collected from the GLOBOCAN 2020.

Background: Radiotherapy is the primary treatment for patients with nasopharyngeal carcinoma (NPC); however, almost 20% of patients experience treatment failure due to radioresistance. Therefore, understanding the mechanisms of radioresistance is imperative. HOTAIRM1 is deregulated in various human cancers, yet its role in NPC radioresistance are largely unclear.

Article Synopsis
  • Immunotherapy for gastrointestinal (GI) tract cancers has gained significant importance, especially through the use of immune checkpoint inhibitors (ICIs) like PD-1 and PD-L1 antibodies.
  • Currently, a combination of anti-PD-1 with chemotherapy is the preferred first-line treatment for various advanced GI cancers, including gastric/gastroesophageal junction adenocarcinoma, dMMR/MSI-H colorectal cancer, and advanced esophageal cancer.
  • Despite these advancements, researchers are still working to enhance the precision and effectiveness of immunotherapy for GI tumors, while also exploring innovative approaches like CAR-T therapy targeting claudin18.2 for later-line treatments.
