Article Synopsis
- Mirror Therapy is a rehabilitation approach for stroke patients that uses a mirror to create the illusion of movement in their impaired arm by showing the movement of the unaffected arm.
- Recent research explores combining Mirror Therapy with immersive virtual reality (VR) technology to enhance therapy using muscle sensors for grasping tasks.
- A study involving 18 healthy participants found that while both unimanual and bimanual visual feedback setups are effective, the VR application showed positive usability and minimal side effects, indicating its potential for stroke rehabilitation despite no major performance differences between the two setups.
Article Synopsis
- The study focused on understanding how adventitious roots (AR) form in stems compared to hypocotyls, aiming to improve vegetative propagation in crops.
- Various methods, including anatomy observations and gene expression analysis, were used to develop a rooting protocol and trace AR origins in Arabidopsis thaliana stems.
- Key findings revealed that while AR formation occurs in both hypocotyls and stems, it is slower in stems and primarily originates from specific cells, with some genes showing delayed expression in stems compared to hypocotyls.
KNOX (knotted1-like homeobox) genes have a widely conserved role in the generation of dissected leaves. Ectopic KNOX activity in leaves in various angiosperm lineages causes leaf form changes that can elucidate how the configuration of leaf development evolved. We present an analysis of leaf morphology and morphogenesis in transgenic Kohleria lines overexpressing a heterologous KNOX gene.

Higher number of roots per disc (8.4) after 21 days of cultivation were formed after a 24-h pulse of 15 microM AD, compared to control without AD application (6.
