The aim of the current study was to evaluate the clinical effectiveness of voice training on patients with vocal cord polyps after phonomicrosurgery. The experimental group included 55 patients with vocal cord polyps after phonomicrosurgery that underwent voice training. Laryngostroboscopy, Voice Handicap Index (VHI), and Dysphonia Severity Index (DSI) were applied to evaluate patient voice qua...

Multi-shell and diffusion spectrum imaging (DSI) are becoming increasingly popular methods of acquiring diffusion MRI data in a research context. However, single-shell acquisitions, such as diffusion tensor imaging (DTI) and high angular resolution diffusion imaging (HARDI), still remain the most common acquisition schemes in practice. Here we tested whether multi-shell and DSI data have conver...

Impaired social interaction is a hallmark symptom of many psychiatric diseases, including dependence syndromes (substance use disorders). Helping the addict reorient her/his behavior away from the drug of abuse toward social interaction would be of considerable therapeutic benefit. To study the neural basis of such a reorientation, we have developed several animal models in which the attractive...

Several types of neurons are able to regulate their synaptic inputs via releasing retrograde signal molecules, such as endocannabinoids or nitric oxide (NO). Here we show that, during activation of cholinergic receptors, retrograde signaling by NO controls CB1 cannabinoid receptor (CB1R)-dependent depolarization-induced suppression of inhibition (DSI). Spontaneously occurring IPSCs were recorde...

We define and study stochastic discrete scale invariance (DSI), a property which requires invariance by dilation for certain preferred scaling factors only. We prove that the Lamperti transformation, known to map self-similar processes to stationary processes, is an important tool to study these processes and gives a more general connection: in particular between DSI and cyclostationarity. Some...

OBJECTIVES To examine whether nursing home residents with concurrent vision and hearing impairment, dual sensory impairment (DSI), have a greater cognitive decline over time than do those without sensory impairment and whether social engagement modifies this association. METHODS Based on the Services and Health for Elderly in Long TERm Care study, 1,989 nursing home residents who were assesse...
