Effect of Use of N-95 Mask on Aided Speech Identification Scores in Older Adults with Hearing Loss.

The present study aimed to investigate the effect of use of N-95 masks on aided speech identification scores (SIS) in older adults with hearing loss. A total of 35 older adults in the age range of 60 years to 79 years (mean age of 64.97 years) participated in the present study.

Effects of the iron oxide nanoparticle Molday ION Rhodamine B on the viability and regenerative function of neural stem cells: relevance to clinical translation.

An essential component of developing successful neural stem cell (NSC)-based therapies involves the establishment of methodologies to noninvasively monitor grafted NSCs within brain tissues in real time. In this context, ex vivo labeling with ultrasmall superparamagnetic iron oxide (USPIO) particles has been shown to enable efficient tracking of transplanted NSCs via magnetic resonance imaging (MRI). However, whether and how USPIO labeling affects the intrinsic biology of NSCs is not thoroughly understood, and remains an active area of investigation.
