Multiple Gas-Containing Renal Stones: A Case Report.

BACKGROUND Emphysematous urinary tract infections are rare and serious conditions that are often multifactorial in etiology and may be associated with the presence of renal stones. Diagnosis can be made by finding gas within the renal collecting system or parenchyma. However, the radiographic finding of gas within a renal stone is rare and little has been published to describe the significance of this finding, its promoting factors, and management.

HiCrayon reveals distinct layers of multi-state 3D chromatin organization.

Chromatin contact maps are often shown as 2D heatmaps and visually compared to 1D genomic data by simple juxtaposition. While common, this strategy is imprecise, placing the onus on the reader to align features with each other. To remedy this, we developed HiCrayon, an interactive tool that facilitates the integration of 3D chromatin organization maps and 1D datasets.

The chromatin tapestry as a framework for neurodevelopment.

The neuronal nucleus houses a meticulously organized genome. Within this structure, genetic material is not simply compacted but arranged into a precise and functional 3D chromatin landscape essential for cellular regulation. This mini-review highlights the importance of this chromatin landscape in healthy neurodevelopment, as well as the diseases that occur with aberrant chromatin architecture.

Structure, Function, and Activity of Small Molecule and Peptide Inhibitors of Protein Arginine Methyltransferase 1.

Protein arginine -methyltransferases (PRMT) are a family of -adenosyl-l-methionine (SAM)-dependent enzymes that transfer methyl-groups to the ω-N of arginyl residues in proteins. PRMTs are involved in regulating gene expression, RNA splicing, and other activities. PRMT1 is responsible for most cellular arginine methylation, and its dysregulation is involved in many cancers.
