Case report: Endolymphatic sac tumor with blurred vision.

Front Oncol

January 2025

The Second Clinical Medicine College, Jinan University, Shenzhen, China.

Introduction: Endolymphatic sac tumor (ELST) is a rare neoplasm that exhibits aggressive growth primarily in the endolymphatic capsule and can potentially affect nearby neurovascular structures. The diagnosis of ELST poses challenges due to its low prevalence, gradual progression, and nonspecific symptomatology. It is currently believed that prompt surgical intervention is recommended for endolymphatic sac tumors upon diagnosis.

Inflammatory myofibroblastic tumors (IMTs) are rare mesenchymal neoplasms with intermediate biological potential and are characterized by spindle-shaped myofibroblastic cells and significant inflammatory infiltrates. This case report describes a 24-year-old male with diabetes who was admitted to the hospital for over three days of vomiting and abdominal pain and was initially diagnosed with diabetic ketoacidosis. Upon admission, an abdominal CT scan revealed a large cystic-solid mass in the abdominal cavity and multiple nodules in the mesentery, omentum, and peritoneum, suggesting a preliminary diagnosis of an intra-abdominal mesenchymal tumor with peritoneal metastasis.

People with advanced chronic liver disease (ACLD) have an enhanced risk of malnutrition, which has multifactorial etiology and is mainly linked to a reduced energy and protein intake; malnutrition is critical for patients with cirrhosis since it is often associated with sarcopenia, a skeletal muscle depletion with a loss of muscle mass and function. Late-evening snacks have been extensively studied, and guidelines are recommended to counteract the effects of prolonged fasting at night in patients with ACLD. However, it has not been fully explored whether late evening snacking is clarified as a milestone to address the nutritional needs of people with ACLD or whether it has a potential role in improving body composition.

Superstrong Lightweight Aerogel with Supercontinuous Layer by Surface Reaction.

Adv Mater

January 2025

Key Laboratory of Precision and Intelligent Chemistry, CAS Key Laboratory of Mechanical Behavior and Design of Materials, Department of Precision Machinery and Precision Instrumentation, National Synchrotron Radiation Laboratory, Center for Micro and Nanoscale Research and Fabrication, Institute of Advanced Technology, University of Science and Technology of China, Hefei, 230026, P. R. China.

Breaking the thermal, mechanical and lightweight performance limit of aerogels has pivotal significance on thermal protection, new energy utilization, high-temperature catalysis, structural engineering, and physics, but is severely limited by the serious discrete characteristics between grain boundary and nano-units interfaces. Herein, a thermodynamically driven surface reaction and confined crystallization process is reported to synthesize a centimeter-scale supercontinuous ZrO nanolayer on ZrO-SiO fiber aerogel surface, which significantly improved its thermal and mechanical properties with density almost unchanged (≈26 mg cm). Systematic structure analysis confirms that the supercontinuous layer achieves a close connection between grains and fibers through Zr─O─Si bonds.

Innovating nanocatalysts with both high intrinsic catalytic activity and high selectivity is crucial for multi-electron reactions, however, their low mass/electron transport at industrial-level currents is often overlooked, which usually leads to low comprehensive performance at the device level. Herein, a Cl/O etching-assisted self-assembly strategy is reported for synthesizing a self-assembled gap-rich PdMn nanofibers with high mass/electron transport highway for greatly enhancing the electrocatalytic reforming of waste plastics at industrial-level currents. The self-assembled PdMn nanofiber shows excellent catalytic activity in upcycling waste plastics into glycolic acid, with a high current density of 223 mA cm@0.

Background: Muscle atrophy is associated with Type 2 diabetes mellitus, which reduces the quality of life and lacks effective treatment strategies. Previously, it was determined that human umbilical cord mesenchymal stromal cell (hucMSC)-derived exosomes (EXOs) ameliorate diabetes-induced muscle atrophy. However, the systemic application of EXOs is less selective for diseased tissues, which reduces their efficacy and safety associated with their nonspecific biological distribution in vivo.
