Lesions to primary sensory and posterior parietal cortices impair recovery from hand paresis after stroke

Neuroanatomical determinants of motor skill recovery after stroke are still poorly understood. Although lesion load onto the corticospinal tract is known to affect recovery, less is known about the effect of lesions to cortical sensorimotor areas. Here, we test the hypothesis that lesions of somatosensory cortices interfere with the capacity to recover motor skills after stroke.

Revisioning a Japanese Spiritual Recovery Through Manga: Kobayashi Yoshinori’s ‘Gōmanism’ as Aesthetics and Ideology

This essay provides a critical analysis of the aesthetic ideology of “Gomanism” in the manga of Kobayashi Yoshinori (b. 1953), particularly Yasukuniron (On Yasukuni, 2005) and Tennōron (On the Emperor, 2009), in order to flesh out the implications of the author’s “revisionist” approach to Japanese religion, politics and history.

Cell therapies for heart function recovery: focus on myocardial tissue engineering and nanotechnologies

Cell therapies have gained increasing interest and developed in several approaches related to the treatment of damaged myocardium. The results of multiple clinical trials have already been reported, almost exclusively involving the direct injection of stem cells. It has, however, been postulated that the efficiency of injected cells could possibly be hindered by the mechanical trauma due to the injection and their low survival in the hostile environment. It has indeed been demonstrated that cell mortality due to the injection approaches 90%. Major issues still need to be resolved and bed-to-bench followup is paramount to foster clinical implementations. The tissue engineering approach thus constitutes an attractive alternative since it provides the opportunity to deliver a large number of cells that are already organized in an extracellular matrix. Recent laboratory reports confirmed the interest of this approach and already encouraged a few groups to investigate it in clinical studies. We discuss current knowledge regarding engineered tissue for myocardial repair or replacement and in particular the recent implementation of nanotechnological approaches.
