We review the current technology underlying surface haptics that converts passive touch surfaces to active ones (machine haptics), our perception of tactile stimuli displayed through touch surfaces (human haptics), their potential applications (human-machine interaction), and finally the challenges ahead of us in making them available through…[Read more]

METHODS Patients hospitalised for acute HF were enrolled in the Korean Acute Heart Failure registry, a prospective, observational, multicentre cohort study, between March 2011 and…[Read more]

The goal of this study was to compare the clinical and radiological outcomes between fenestrated pedicle screws augmented with cement and expandable pedicle screws in percutaneous vertebral fixation surgical procedures for the treatment of degenerative and traumatic spinal diseases in aging patients with osteoporosis.

A transdermal drug delivery system (TDDS) is generally designed to deliver an active pharmaceutical ingredient (API) through the skin for systemic action. Permeation of an API through the skin is controlled by adjusting drug concentration, formulation composition, and patch design. A bilayer, drug-in-adhesive TDDS design may allow improved…[Read more]

017) than patients without LUTS. They also scored more poorly on muscle function tests. Urodynamic results point to neurogenic causes for LUTS in LOPD, that is, neurogenic reflex bladder or impaired filling sensation. This could be due to glycogen accumulation in the urothelium and central nervous system. Patients with LUTS also seem to be more…[Read more]
