Article Synopsis
  • Gelatin methacryloyl (GelMA) is a semi-synthetic polymer that can be fine-tuned to create hydrogels with various microstructures, which are important for many bioapplications.
  • Researchers explored how applying shear to a solution of GelMA and dextran can create different hydrogel structures and used rheology and UV-curing to study this process.
  • The findings reveal that changing factors like dextran concentration and pH can lead to diverse structures, such as aligned bands and porous microgels, showcasing the potential for developing advanced materials through this method.

Background: Androgen deprivation therapy (ADT) is prescribed to almost half of all men diagnosed with prostate cancer. Although ADT is effective treatment, with virtually all men with advanced disease showing initial clinical response, it is associated with troublesome side effects including hot flushes and night sweats (HFNS). HFNS can be both frequent and severe and can have a significant impact on quality of life (QoL).

There has been a significant development of digital interventions for the treatment of Post-Traumatic Symptom Disorder (PTSD) over the past two decades. However, the majority of research has examined their clinical efficacy for military service members and veteran populations whereas community-based trauma survivors have received significantly less attention. Their effectiveness for this population, therefore, remains unclear.

We use video particle tracking microrheology (VPTMR) in order to investigate the viscoelasticity of salmon DNA and correlate it to its steady-flow shear-thinning viscosity. Aqueous solutions of DNA are tested in a wide concentration range from the dilute to the semidilute unentangled concentration regime. The observed mean squared displacement shows power-law scaling with lag-time which is equivalent to power-law behavior of the complex modulus as a function of frequency that is, |G (ω)| = S ∙ ω .
