A flexible sensor that can be attached to the body to collect vital data wirelessly enables real-time human healthcare management. One potential application for home-use healthcare devices is monitoring of sleep conditions to diagnose sleep apnea syndrome. Such data are not readily gathered using conventional tools, owing to the bulk and cost of instrumentation.

Coronary artery (CA) stenosis is a detrimental and often life-threatening sequela in Kawasaki disease (KD) patients with coronary artery aneurysm (CAA). Therapeutic strategies for these patients have not yet been established. All-trans-retinoic acid (atRA) is a modulator of smooth muscle cell functions.

Recurrent medulloblastoma can be difficult to diagnose with conventional diagnostic methods because other lesions mimic tumor relapse, particularly at later stages. We report 2 cases of medulloblastoma, both of which seemed to develop late recurrences. Case 1 was a 6-year-old girl who had a medulloblastoma with focal desmoplasia.

A disorder in the thermoregulator center in a human body leads to some potential diseases such as fever and hyperthyroidism. To predict these diseases early, monitoring the health condition of the human body due to the influence of thermoregulation disorders is important. Although extensive works are performed on sweat-rate detection by constructing microfluidic channels, skin-moisture evaporation before sweating remains unknown.

Continuous multiple data health monitoring has high potential to detect abnormal conditions or early stages of diseases in the future. To monitor a continuous small vital signal, one of the promising architectures is an attachable flexible multimodal sensor system, which can detect multiple health conditions from the skin surface. Recent breakthroughs have realized continuous sweat chemicals or physical conditions using flexible sensors.

Emerging feedback systems based on tracking body conditions can save human lives. In particular, vulnerable populations such as disabled people, elderly, and infants often require special care. For example, the high global mortality of infants primarily owing to sudden infant death syndrome while sleeping makes request for extraordinary attentions in neonatal intensive care units or daily lives.

Real-time, daily health monitoring can provide large amounts of patient data, which may greatly improve the likelihood of diagnosing health conditions at an early stage. One potential sensor is a flexible humidity sensor to monitor moisture and humidity information such as dehydration. However, achieving a durable functional nanomaterial-based flexible humidity sensor remains a challenge due to partial desorption of water molecules during the recovery process, especially at high humidities.

Kawasaki disease (KD), a febrile systemic vasculitis in infants associated with coronary aneurysm, is a major cause of cardiac sequelae such as myocardial infarction (MI) and sudden death. These events are caused by coronary stenosis due to intimal proliferation or thrombotic formation; however, histological evaluation is limited to autopsy cases of human KD. We therefore investigated the histological features of coronary artery (CA) stenosis in mice induced by Lactobacillus casei cell wall extract (LCWE).

As antineutrophil cytoplasmic antibody positive rapidly progressive glomerulonephritis (ANCA-RPGN) has a high risk of end stage renal failure and is a potentially life threatening disease, early aggressive therapy is recommended. However, aggressive immunosuppressive therapy may lead to immunodeficiency and subsequent mortality in the patients with this disease. Therefore, we need the index of immunodeficiency to cure the disease.
