Whisking mechanics and active sensing [PDF]

Current Opinion in Neurobiology, 2016
We describe recent advances in quantifying the three-dimensional (3D) geometry and mechanics of whisking. Careful delineation of relevant 3D reference frames reveals important geometric and mechanical distinctions between the localization problem ('where' is an object) and the feature extraction problem ('what' is an object).

A cholesterol-sensing mechanism unfolds [PDF]

Journal of Biological Chemistry, 2017
Squalene monooxygenase (SM), which synthesizes a cholesterol precursor, is degraded when cholesterol levels in the endoplasmic reticulum (ER) membrane are high, but the signal for degradation was not known. In this issue of JBC, Brown and co-workers identify an N-terminal domain in SM that interconverts in a cholesterol-sensitive manner between a ...

Prolonged Corrected QT Interval as an Early Electrocardiographic Marker of Cyclophosphamide‐Induced Cardiotoxicity in Pediatric Hematology and Oncology Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cyclophosphamide (CY) is associated with potentially fatal cardiotoxicity, yet no electrocardiographic indices have been established for early detection of CY‐induced cardiomyopathy. This study aimed to determine whether corrected QT interval (QTc) prolongation can predict early onset of CY‐related cardiac dysfunction in pediatric ...
