In this study, we used Raman spectroscopy to observe the process of osteoblast calcification under microvibration stimulation. Osteoblast cultures were prepared under three conditi...

Evaluation of biomaterial properties using THP-1 cells require the establishment of standardized protocols. Two potential methods are available, which differ in the timing of cell ...

The prevention of dementia is a pressing issue on a global scale. One of the most important recommendations in the World Health Organization's guidelines entitled “Risk reduction o...

Implantable ventricular assist devices (iVADs) are commonly used to treat patients with severe heart failure. To ensure safe and reliable operation of iVADs, it is crucial to devel...

Alpha-rhythm enhancement during memory maintenance has been explained as active inhibition of task-irrelevant visual inputs because the enhancement is generally observed in occipit...

Transcranial magnetic stimulation (TMS) is a widely used non-invasive neurostimulation technique in neuroscience and in the treatment of psychiatric disorders. By placing a TMS coi...

As the impact of population aging becomes increasingly serious, more problems emerge with regard to medical and long-term care for the older individuals, which require solution. In...

Compound plane-wave imaging (CPWI) is a widely used and investigated imaging technique in medical ultrasound because it provides high quality ultrafast imaging for recent applicati...

Most sports-assisting technologies have been developed to improve performances only in individual sports such as skiing, batting, and swimming. In team sports, it is important to p...

Falls in older adults is a major public health issue with approximately one-third of individuals aged 65 or older experiencing at least one fall event annually. Accordingly, there ...

Human error during surgery can cause unexpected accidents. Elucidating the causes of human error by monitoring the behavior of the surgical team can improve safety. Conventional me...

Tear film stability is essential for maintaining the health of the ocular surface. A tear film interferometer allows noninvasive observation of the dynamics of the tear film lipid ...

The mechanism of hallux valgus (HV) development has not been fully clarified, and a new evaluation method is required. We aimed to establish a method for calculating the rotational...

Motion analysis can be performed during walking by measuring the contact pressure and shear stress acting on the body surface. Although floor reaction force gauges and stress senso...

In this study, we successfully produced a scaffold-free cell construct for regenerative medicine using the Kenzan method, which involves the fusion of spheroids on a needle array. ...

Brain-computer interface (BCI) has attracted attention as a means of assisting patients with intractable neurological diseases to communicate their intentions. However, there are n...

The COVID-19 pandemic has an impact on people's ability to exercise and walk. Decreased exercise habit leads to decreased muscle mass, which may hamper social activities. The decli...

Recently, the number of health-related car accidents in Japan has been increasing. Most health conditions leading to traffic accidents are detectable by analyzing the fluctuation i...

Since all of noninvasive optical monitors such as near-infrared spectroscopy are transcutaneous, it is important to consider the optical properties of the skin. The purpose of the ...

For older people who live alone, we previously designed a system that enabled family members at distant locations to monitor television (TV) usage and other activities of the older...
