Background: Accurate prediction of lung tumor motion and deformation (LTMD) is essential for precise radiotherapy. However, existing models often rely on static, population-based material parameters, overlooking patient-specific and time-varying lung biomechanics. Personalized dynamic models that capture temporal changes in lung elasticity are needed to improve LTMD prediction and guide treatment planning more effectively.

Auxiliary buttons are often required in clear aligner therapy for elastic traction. We introduce an adhesiveless flame-fusion technique for affixing auxiliary metal buttons to clear aligners, aiming to eliminate the extra chair time, occasional debonding, and translucent haze associated with resin adhesives. Round‑base stainless‑steel buttons are grasped with locking forceps, heated in an alcohol flame (~600-650 °C for 10-15 s), and immediately pressed with moderate manual pressure (~5 N) for 5-10 s onto 0.

We present a high-throughput method using standard laboratory equipment and microfluidics to produce cellular force microscopy probes with controlled size and elastic modulus. Mechanical forces play crucial roles in cell biology but quantifying these forces in physiologically relevant systems remains challenging due to the complexity of the native cell environment. Polymerized hydrogel microspheres offer great promise for interrogating the mechanics of processes inaccessible to classic force microscopy methods.

The tensile strength of the umbilical cord (UC) is influenced by its composition-including collagen, elastin, and hyaluronan-contributing to its unique biomechanical properties. This experimental in vitro study aimed to evaluate the UC's mechanical behavior under varying strain rates and to characterize its viscoelastic response. Twenty-nine UC specimens, each 40 mm in length, were subjected to uniaxial tensile testing and randomly assigned to three traction speed groups: Group A ( = 10) at 8 mm/min, Group B ( = 7) at 12 mm/min, and Group C ( = 12) at 16 mm/min.

Sinking skin flap syndrome (SSFS) is a rare but significant complication after decompressive craniectomy, caused by atmospheric pressure compressing the brain through a cranial defect. Although cranioplasty is the primary treatment, infection may delay reconstruction, leaving patients vulnerable to progressive neurological decline. The authors report a case of SSFS after removal of infected cranial implants.
