Purpose: This study aimed to identify trajectories of physical activity behavior from discharge up to 6-8 years after rehabilitation among adults with physical disabilities and/or chronic diseases, and to determine modifiable determinants associated with trajectory membership.

Material And Methods: 390 Adults with physical disabilities and/or chronic diseases participated in the Rehabilitation, Sports and Active lifestyle (ReSpAct) 2.0 study with measurements at 3-6 weeks before discharge (T0), and 14 (T1), 33 (T2), and 52 weeks (T3), and 6-8 years (T4) after discharge from rehabilitation.

Mode-locked lasers are of interest for applications such as biological imaging, nonlinear frequency conversion, and single-photon generation. In the infrared, chip-integrated mode-locked lasers have been demonstrated through integration of laser diodes with low-loss photonic circuits. However, additional challenges, such as a higher propagation loss and smaller alignment tolerances, have prevented the realization of such lasers in the visible range.

Article Synopsis
  • This study explores the views and experiences of individuals who have had major lower limb amputations due to blood circulation issues, focusing on their nutritional habits and challenges.
  • Thirteen participants shared insights through interviews, leading to four key themes: food choices are influenced by non-health factors, there is a lack of understanding about nutrition's impact on health, support for nutrition mainly comes from personal networks rather than professionals, and there is minimal motivation to change eating habits.
  • The study emphasizes the need for better awareness of healthy eating and suggests that personalized nutritional care, using motivational interviewing techniques, could enhance health outcomes for these individuals.

This work describes the development of a novel biosensor obtained by immobilizing laccase from Pleurotus ostreatus Florida onto a glassy carbon electrode platform modified with zinc oxide quantum dots. For enzyme immobilization, the exopolysaccharide botryosphaeran from Botryosphaeria rhodina MAMB-05 was used. Although both biomaterials are from different fungal sources, laccase immobilization was guaranteed, which was demonstrated by the excellent stability of the fabricated biosensor device for the voltammetric determination of 2,6-dimethoxyphenol (2,6-DMP).

We present hybrid-integrated extended cavity diode lasers tunable around 637 nm, with a gain-wide spectral coverage of 8 nm. This tuning range addresses the zero-phonon line of nitrogen-vacancy centers and includes the wavelength of HeNe lasers (633 nm). Best performance shows wide mode-hop free tuning up to 97 GHz and a narrow intrinsic linewidth down to 10 kHz.
