Article Synopsis
- - This study explores the creation of new functional complexes using aluminum ions, focusing on dinuclear triple-stranded helicates with brominated Schiff base ligands.
- - Researchers synthesized both homoleptic and heteroleptic complexes and found that more bromination led to a shift in emission color from yellow to orange, revealing unique optical properties.
- - Advanced techniques like X-ray structural analysis and ultrafast spectroscopy showed that the optical properties are influenced by interligand charge transfer, particularly in heteroleptic complexes, providing insights into photofunctional materials.
Article Synopsis
- This study focused on developing functional dyes using aluminum-based dinuclear triple-stranded helicates, emphasizing how variations in substituents affect their structural and optical properties.
- Key findings showed that changing methyl groups on pyrrole positions lengthened the conjugation system, causing a red shift in spectra, while modifications at methine positions increased torsion angles, resulting in a blue shift.
- The research also explored the chiroptical properties of the new complexes, highlighting their potential applications in fields like materials science and optoelectronics due to their unique optical behaviors.
Benzophenone and its derivatives emit crystallization-induced phosphorescence despite their simple structures. To easily modify their phosphorescence properties, we prepared phosphorescence-emitting aqueous solutions of polysaccharide-benzophenone and polysaccharide-4,4'-difluorobenzophenone complexes, which exhibit excellent biocompatibility and biodegradability.

This study is a prospective evaluation of the effectiveness of cardiac rehabilitation (CR) in terms of clinical outcomes for small abdominal aortic aneurysms (AAA) that were previously reported in a retrospective cohort study. We conducted a prospective non-randomized trial on patients with small AAA (N = 40; mean age 75.0 ± 6.

Open Med (Wars)
September 2018
Performing accurate diagnosis using computed tomography (CT) in emergency medicine may reduce mortality rates in various diseases. In this observational, correlational and cross-sectional study, we conducted multiple regression analyses to investigate the relationship between CT utilization rates and mortality. In addition, we estimated the annual net profits from CT to show the profitability of introducing a CT system in each Japanese prefecture.

Twenty-four consecutive patients with advanced symptomatic heart failure who were referred for cardiac transplant evaluation were recruited. After performing aerobic exercise for approximate intensity, high-intensity interval training (HIIT) was performed.

This study was performed with use of phantoms made from water and sucrose at different concentrations, which were 10, 30, and 50 weight percent (wt%). In noise reduction for Dw imaging of the phantoms, we compared two correction schemes that are based on the Rician distribution and the Gaussian distribution.

Annu Int Conf IEEE Eng Med Biol Soc
March 2008
Article Synopsis
- The myoelectric hand is an artificial prosthetic that is controlled by electromyographic (EMG) signals from muscle contractions in the user's upper limb stump.
- Controlling the device requires two different signals, and identifying the optimal placement of electrodes to capture these signals can be time-consuming.
- The study focuses on creating a system that can efficiently determine the best electrode positions using a band-type multi-electrode setup, which has been validated for effectively controlling a myoelectric hand for upper limb amputees.
