Single-molecule spectroscopy (SMS) of a dual fluorescent flapping molecular probe (N-FLAP) enabled real-time nanoscale monitoring of local free volume dynamics in polystyrenes. The SMS study was realized by structural improvement of a previously reported flapping molecule by nitrogen substitution,...

Generation mechanisms of bowel sounds by simultaneous measurements of X-ray fluoroscopy and bowel sounds.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference

Saito SN, Otsuka S, Zenbutsu S, Hori S, Honda M, Nakagawa S.
PMID: 34891589
Annu Int Conf IEEE Eng Med Biol Soc. 2021 Nov;2021:1593-1596. doi: 10.1109/EMBC46164.2021.9629486.

In clinical practice, bowel sounds are often used to assess bowel motility. However, the diagnosis differs depending on the literature because diagnoses have been based on empirically established criteria. To establish diagnostic criteria, researching the mechanism of bowel-sound occurrence...

Characteristics of anatomical difficulty for cryoballoon ablation: insights from CT.

Open heart

Hayashi T, Murakami M, Saito S, Iwasaki K.
PMID: 34992156
Open Heart. 2022 Jan;9(1). doi: 10.1136/openhrt-2021-001724.

BACKGROUND: The limited availability of balloon sizes for cryoballoon leads to anatomical limitations for pulmonary vein (PV) isolation. We conducted a comprehensive systematic analysis on procedural success rate, atrial fibrillation (AF) recurrence rate and complications of cryoballoon ablation in...

Amyloid PET quantification using low-dose CT-guided anatomic standardization.

EJNMMI research

EJNMMI Res. 2021 Dec 14;11(1):125. doi: 10.1186/s13550-021-00867-7.

BACKGROUND: Centiloid (CL) scaling has become a standardized quantitative measure in amyloid PET because it facilitates the direct comparison of results across institutions, even when different analytical methods or tracers are used. Standard volumes of interest must be used...

Discussion on effect of material on UV reflection and its disinfection with focus on Japanese Stucco for interior wall.

Scientific reports

Endo T, Gemma A, Mitsuyoshi R, Kodama H, Asaka D, Kono M, Mochizuki T, Kojima H, Iwamoto T, Saito S.
PMID: 34750445
Sci Rep. 2021 Nov 08;11(1):21840. doi: 10.1038/s41598-021-01315-1.

Research has previously shown that ultraviolet light C (UV-C) can inactivate unexpected infection. However, this type of potential disinfection is dramatically reduced for the shadow area such as under desk or medical equipment. Because the UV-C reflectance ratio is...
