Artificially reproducing smell sensations, without using chemical odorants, would change the future multisensory internet experiences. This article presents a computer-controlled reproduction technology proposed for stimulating human olfactory receptors, weak electric pulses. We developed concept prototype that can generate rectangular-shaped electrical pulses in different frequencies (0–30 kHz...

To explore the nature of the olfactory dysfunction associated with Parkinson's disease (PD), 81 PD patients who scored well on a cognitive screening test were administered the 40-odorant University of Pennsylvania Smell Identification Test; 38 were additionally given a forced-choice phenylethyl alcohol odor detection threshold test. Clinical ratings of 11 neurologic symptoms (three bilateral) w...

AIM To evaluate Lancefield grouping and caramel smell for presumptive identification of the Streptococcus milleri group, and to find whether Lancefield group, species, or protein profile correlated with virulence or infection site. METHODS Prospective studies were made of 100 consecutive streptococcal isolates in blood cultures or pus from 100 patients in whom the severity of infection was ca...

This study described the San Diego Odor Identification Test (SDOIT) reliability and compared the SDOIT and the Brief Smell Identification Test (B-SIT). Ninety participants aged 50-70 years completed this 2-visit olfaction study. During visit 1, the SDOIT and B-SIT were administered according to standard protocols. Three weeks later, participants returned to retake the SDOIT. The SDOIT score was...

The urinary excretion of (an) odorous substance(s) after eating asparagus is not an inborn error of metabolism as has been supposed. The detection of the odour constitutes a specific smell hypersensitivity. Those who could smell the odour in their own urine could all smell it in the urine of anyone who had eaten asparagus, whether or not that person was able to smell it himself. Thresholds for ...

This study aims to formulate and evaluate the preparation of an anti-aging cream made from astaxanthin. Astaxanthin has antioxidant activity, as well other carotenoid compounds. shows more significant activity than ?-carotene; thus,developing astaxanthin compounds in preparations is necessary. type experimental laboratory research compares three different concentrations compounds, including for...

J Otolaryngol ENT Res 2017, 6(4): 00173 sinus surgery. Patients undergoing bilateral frontal sinusotomy, ethmoidectomy, maxillary antrostomy, and sphenoidotomy were considered to have undergone “complete” surgery, whereas all other participants were categorized as receiving “targeted” surgery. Improvement was evaluated between surgical subgroups with at least 6-month follow up using the 22-item...
