Rolling of stimuli-bent cylindrical robots using contact finite element simulations.

Curved cylinders, if rigid, cannot roll on a surface like straight cylinders, but soft cylinders bent by specific stimuli can! Studying the autonomous locomotion of these soft robots and their interactions with the environment using finite element analysis is challenging due to the complex multiphysics of stimuli-responsive soft materials and nonlinear contact mechanics. In this pioneering work, we simulate the rolling of stimuli-bent cylinders on a surface using contact finite elements and introduce a simple yet effective pseudo-thermal field method. Our approach successfully reproduces several modes of autonomous locomotion observed experimentally, including phototropic locomotion, phototropic climbing on a slanted surface, steering under partial illumination, and backward rolling under alternating heat-light stimuli.

Physiologically Based Pharmacokinetic Model of Tyrosine Kinase Inhibitors to Predict Target Site Penetration, with PET-Guided Verification.

Osimertinib, a tyrosine kinase inhibitor (TKI), treats non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations. However, its efficacy may vary due to heterogeneous drug distribution, assessable through microdosed radiolabeled drugs and positron emission tomography (PET). Precision dosing using microdosed TKI-PET encounters challenges due to pharmacokinetic (PK) variations between micro- and therapeutic doses.

Long-term health-related quality of life among adolescent and young adult breast cancer survivors.

Purpose: As the prognosis for adolescents and young adults (AYAs) with breast cancer has improved, long-term health-related quality of life (HRQoL) has become increasingly important. This study aimed to analyze the long-term HRQoL of AYA breast cancer survivors compared to an age-matched normative population and to identify factors associated with HRQoL.

Methods: Secondary analyses were conducted using data from the SURVAYA study.

"Aiming at a moving target"-The daily life experiences of adolescents and young adults with a low-grade glioma.

Background: Low-grade gliomas (LGG) are among the most frequently occurring tumors in adolescent and young adult (AYA) patients (aged 18-39 years old at primary diagnosis). These tumors have a variable prognosis, presenting challenges for patients in shaping their future. This study aimed to identify the age-specific experiences and needs of AYA patients with LGG in their daily lives.

Adverse health outcomes and health-related quality of life (HRQoL) among long-term adolescent and young adult (AYA) brain tumour survivors: results from the population-based SURVAYA study.

Purpose: Adolescent and young adult (AYA) malignant brain tumour (BT) survivors are at risk of adverse health outcomes, which may impact their health-related quality of life (HRQoL). This study aimed to investigate the (1) prevalence of physical and psychological adverse health outcomes, (2) the HRQoL, and (3) the association of adverse health outcomes and HRQoL among long-term AYA-BT survivors. Adverse health outcomes and HRQoL were compared to other AYA cancer (AYAC) survivors.
