Precursor transfer RNAs (pre-tRNAs) are early forms of tRNAs that need precise trimming at both ends to become active for protein production. Bacteria and archaea use small enzymes called “HARPs” to achieve this cleavage, but how exactly this happens remains unclear. Now, researchers from Kyushu University have uncovered that HARPs form a star-shaped complex of 12 units, enabling it to perform both 5’ and 3’ end cleavages—conferring it “dual-functionality.”
To simulate blood flow inside brain aneurysms, researchers from Japan developed a computational method that combines 4D flow MRI, computational fluid dynamics, and data assimilation, which provides greater accuracy and efficiency. By focusing only on the aneurysm region, this approach significantly reduces computational cost while improving flow estimation. When validated on patient data, it outperforms conventional models—offering a practical tool for patient-specific risk assessment and treatment strategies.
Inflammation is a natural immune response, but when uncontrolled, it can worsen many diseases. Recent studies show that metabolism plays a surprising role in regulating this response. A new editorial in the Journal of Intensive Medicine highlights findings on the glyoxalase system, a metabolic pathway that helps immune cells tone down inflammation. This insight opens new possibilities for treating inflammatory diseases through metabolic targets, offering a promising direction beyond traditional immunosuppressants.
