We report a case of neoplasm of the urinary bladder with pseudosarcomatous stromal differentiation. Heterologous carcinosarcomas are extremely rare malignant neoplasms (seventy-eight cases have been previously described). This is a case of carcinoma containing numerous osteoclast type giant cells that stained for vinmentin and acid phosphatase and were negative for cytokeratin and lysozyme.

The emerging prevalence of antimicrobial resistance demands cutting-edge therapeutic agents to treat bacterial infections. We present a synthetic strategy to construct sequence-defined oligomers (SDOs) by using dithiocarbamate (DTC). The antibacterial activity of the synthesized library of SDOs was studied using a Gram-positive and a Gram-negative .

In 2024, CD19-CAR T cells are ubiquitous in rheumatology, with incredible therapeutic results in cases of severe and refractory disease. This major advance confirms the interest of the B lymphocyte as a therapeutic target, and also suggests the real possibility of a drug-free remission, at the price of minor and minimal side effects for the time being. However, the necessary perspective is still lacking for a therapy that remains out of reach because of its price.

Cells use 'active' energy-consuming motor and filament protein networks to control micrometre-scale transport and fluid flows. Biological active materials could be used in dynamically programmable devices that achieve spatial and temporal resolution that exceeds current microfluidic technologies. However, reconstituted motor-microtubule systems generate chaotic flows and cannot be directly harnessed for engineering applications.

SARS-CoV-2 is a viral infection, best studied in the context of epithelial cell infection. Epithelial cells, when infected with SARS-CoV-2 express the viral S-protein, which causes host cells to fuse together into large multi-nucleated cells known as syncytia. Because SARS-CoV-2 infections also frequently present with cardiovascular phenotypes, we sought to understand if S-protein expression would also result in syncytia formation in endothelial cells.

Epithelia are multicellular sheets that form barriers defining the internal and external environments. The constant stresses acting at this interface require that epithelial sheets are mechanically robust and provide a selective barrier to the hostile exterior. These properties are mediated by cellular junctions which are physically linked with heavily crosslinked cytoskeletal networks.
