Gravity has long been purported to serve a unique role in sensorimotor coordination, but the specific mechanisms underlying gravity-based visuomotor realignment remain elusive. In this study, astronauts (9 males, 2 females) performed targeted hand movements with eyes open or closed, both on the ground and in weightlessness. Measurements revealed systematic drift in hand-path orientation seen only when eyes were closed and only in very specific conditions with respect to gravity.

However, consensus is lacking in non-radical surgery for infiltrating cancer, and even doubts are cast for patients with laryngeal dysplasia at the resection margins. In this study we aim to assess the prognostic significance of laryngeal dysplasia at the surgical margins in patients radically treated for infiltrating cancer.

Except for the rare malignant cases, MPC mostly shows a benign course. Symptoms are often non-specific, and the diagnosis could be accidental.

The role of a routine prophylactic central neck dissection (PCND) is still debated as its impact on oncologic outcomes has never been cleared by a randomized clinical trial. In this study, we aimed to report our long-standing experience in PCND and its potential contemporary role in the treatment of PTC.
