Undifferentiated carcinomas with osteoclast-like giant cells of the pancreaticobiliary tract (UCOGCs) are rare but distinctive tumors with limited literature. To study the clinicopathologic characteristics of UCOGCs including morphology, immunohistochemistry (IHC), management, and survival outcomes. Assessment of 12 patients of UCOGC found over 10 years from a tertiary care oncology center database.

Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane-fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin "strands" extend between separating chromosomes, connecting their telomeres, just as tethers do. Since titin is responsible for elastic forces in myofibrils, we suggest that titin is responsible for the backwards forces exerted on chromosome arms during anaphase.

Transmembrane signaling is essential for cellular communication, yet reconstituting such mechanisms in synthetic systems remains challenging. Here, we report a simple and robust DNA-based mechanism for transmembrane signaling in synthetic cells using cholesterol-modified single-stranded DNA (Chol-ssDNA). We discovered that anchored Chol-ssDNA spontaneously flips across the membrane of giant unilamellar lipid vesicles (GUVs) in a nucleation-driven, defect-mediated process.

Splenic pseudocysts represent an uncommon condition in abdominal surgery, generally resulting from trauma, infection, or ischemic processes. Histologically, they are characterized by the absence of an epithelial lining; that is, they lack the inner layer of cells typically found in true cysts. Its clinical presentation is non-specific, commonly manifesting with abdominal pain, early satiety, or alterations in bowel habits, which lead to late or incidental diagnoses through imaging studies.

Ferroelectric tunnel junctions (FTJs) based on ferroelectric switching and quantum tunneling effects with thickness down to a few unit cells have been explored for applications of two-dimensional (2D) electronic devices in data storage and neural networks. As a key performance indicator, the enhanced tunneling electrosistance (TER) ratio provides a broader dynamic range for precise modulation of synaptic weights, improving the stability and accuracy of neural networks. Herein, we report an observation of pronounced enhancement in the TER ratio by over 4 orders of magnitude through the fabrication of large-scale heterostructures combining bismuth ferrite with two-dimensional Ruddlesden-Popper oxide BiFeO.
