Background The incidence of pulmonary hypertension (PH) associated with bronchopulmonary dysplasia (BPD) has not been investigated in regional cohorts. The aim of this study was to clarify the incidence of PH associated with BPD in all very low birthweight infants (VLBWIs) born during the study period in Aichi Prefecture, Japan. Methods We conducted a retrospective observational cohort study of...

It has been almost four decades since the first launch of geostationary meteorological satellite by Japan Meteorological Agency (JMA). The specifications of the geostationary meteorological satellites have shown tremendous progresses along with the generations, which are now entering their third generation. The third-generation geostationary meteorological satellites not only yield basic data for...

With the tremendous development of remote sensing technologies, a large amount of observation data are generated from sensors. Since each sensor generates data periodically, e.g., every minute, a concurrent data processing using a cloud system plays an important role in the modern design process. This paper focuses on concurrent data processing techniques for an X-band phased array weather radar (PAWR)...

2016 IEEE 7th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)

For network communications using modern high throughput satellite (HTS) on geostationary orbits, network throughput of transmission control protocol (TCP), one of the most popular protocols, is limited due to the packet loss on the satellite link. The packet loss is mainly caused by the attenuation of signals in severe weather conditions like heavy rain. It is high time to develop novel network communication...

Achieving the quality of service (QoS) is an important requirement in a communication network. Satellite communication is posing many challenges due to the limitation of transmission control protocol (TCP) over networks with high latency. To overcome these issues, the wide area network (WAN) optimization provides the data transfer on such long-distance networks. However, this optimization is not able...

2016 IEEE 7th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)

Large-scale distributed file system is an important technology for big data sciences. Several works so far have succeeded in high-bandwidth data I/O on multi-point to multi-point remote storage systems. However, for easy use by many scientific researchers, high-bandwidth remote storage tools working on a single client computer are preferable. As for high-bandwidth multi-point to single-point remote...

2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)

With the tremendous development of remote sensing technologies, large-scale data sets are collected from environmental and meteorological sensors. Edge computing for large-scale data sets is hard to be conducted in real time on the sensors, thus data transfer to cloud system and data processing play an important role. One of the barriers in such system is high-speed data transfer on long-distance...

Single nucleotide polymorphisms in AGTR1, TFAP2B, and TRAF1 are not associated with the incidence of patent ductus arteriosus in Japanese preterm infants

Koya Kawase, Tokio Sugiura, Yoshiaki Nagaya, Takaharu Yamada, more

Pediatrics International > 58 > 6 > 461 - 466

Background Persistent patent ductus arteriosus (PDA) is a frequent complication in preterm infants. Single nucleotide polymorphisms (SNP) in several genes, including angiotensin II receptor, type 1 (AGTR1), transcription factor AP‐2 beta (TFAP2B) and tumor necrosis factor receptor‐associated factor 1 (TRAF1), have been reported to be associated with PDA in preterm infants. The aim of this study was...

Due to rapid increase of network bandwidth, applications and systems working in long fat network (LFN) play more important roles. For effective development of them, precise measurements of network conditions are significant. Transmission Control Protocol (TCP) is the most commonly used protocol, but is essentially unable to achieve high throughput in LFNs with packet losses. For this reason, it is...

Inflammatory cytokine tumor necrosis factor α suppresses neuroprotective endogenous erythropoietin from astrocytes mediated by hypoxia‐inducible factor‐2α

Yoshiaki Nagaya, Mineyoshi Aoyama, Tetsuya Tamura, Hiroki Kakita, more

European Journal of Neuroscience > 40 > 11 > 3620 - 3626

Interest in erythropoietin (EPO) as a neuroprotective mediator has grown since it was found that systemically administered EPO is protective in several animal models of disease. However, given that the blood–brain barrier limits EPO entry into the brain, alternative approaches that induce endogenous EPO production in the brain may be more effective clinically and associated with fewer untoward side‐effects...

Cellular and Molecular Neurobiology > 2013 > 33 > 3 > 393-400

Acute encephalopathy is a generic term for acute brain dysfunction occurring after infection. Acute encephalopathy induced by influenza virus results in high mortality, and most cases of influenza-associated encephalopathy (IAE) result in brain edema. Administration of diclofenac sodium (DCF), a non-steroidal anti-inflammatory drug (NSAID), is associated with a significant increased mortality rate...

Hiroki Kakita, Mohamed Hamed Hussein, Shin Kato, Yasumasa Yamada, more

Journal of Critical Care > 2012 > 27 > 5 > 469-473

This retrospective case-control study aimed to examine the development of oxidative stress in asphyxiated infants delivered at more than 37 weeks of gestation.Thirty-seven neonates were stratified into 3 groups: the first group experienced hypothermia (n = 6); the second received hypothermia cooling cup treatment for 3 days, normothermia (n = 16); and the third was the control group (n = 15).Serum...
