Tremor Reduction at the Palm of a Parkinson’s Patient Using Dynamic Vibration Absorber
Parkinson’s patients suffer from severe tremor due to an abnormality in their central oscillator. Medications used to decrease involuntary antagonistic muscles contraction can threaten their life. However, mechanical vibration absorbers can be used as an

Acoustic characteristics of voice in examinees with moderately-severe hearing loss [PDF]
Introduction.Voice is the result of vocal cord vibrations and resonance effects of the vocal tract, therefore, the instrumental monitoring of the vibrations themselves is one of the essential aspects of objective instrumental assessment of voice ...

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...
