BACKGROUND: Poor control of body temperature is associated with mortality and major morbidity in preterm infants. We aimed to quantify its dynamics and complexity to evaluate whether indices from fluctuation analyses of temperature time series obtained within the first five days of life are associated with gestational age (GA) and body size at birth, and presence and severity of typical comorbidities of preterm birth. METHODS: We recorded 3h-time series of body temperature using a skin electrode in incubator-nursed preterm infants...

Photo-related nanomedicine is of particular interest as an emerging paradigm toward precise cancer therapy, as demonstrated by the recent developments of photothermal therapy (PTT), an emerging technique employing light converting agents to burn cancerous cells by over-dosed optical energy-converted heat. However, most of the laser irradiations needed for effective PTT significantly exceed the maximal permissible power density in human skin, which is likely to damage surrounding normal tissues. Herein, we report a strategy of intranuclear PTT of cancer enabled by nuclear-targeted delivery of gold nanorods of ~ 10...

MdMYB1 acts as a crucial component of the MYB-bHLH-WD40 (MBW) complex to regulate anthocyanin biosynthesis in red-skinned apples (Malus domestica), but little is known about its posttranslational regulation. Here, a SUMO E3 ligase MdSIZ1 was screened out as an MdMYB1-interacting protein with a yeast two-hybridization approach. The interaction between MdSIZ1 and MdMYB1 was further verified with pull-down and CoIP assays. Furthermore, it was found that MdSIZ1 directly sumoylated MdMYB1 proteins in vivo and in vitro, especially under moderately low temperature (17 °C) conditions, and that this sumoylation was required for MdMYB1 protein stability...

Infrared cameras are becoming increasingly popular in clinical applications as they allow fast, non-contact temperature measurements. As abnormal heat distribution can indicate illness, infrared cameras have been applied in the prediction, diagnosis and monitoring of conditions (Lahiri, Bagavathiappan, Jayakumar, & Philip, 2012). Current practices, however, often overlook the importance of emissivity when taking thermal measurements. The consensus is that human skin has an emissivity of 0.98 (Soerensen et al...

One of the main challenges in the noninvasive sensing of blood glucose by near-infrared (NIR) spectroscopy is the background variations from light source drift, sweating, and temperature change at the human-machine interface. In this paper, a differential correction method based on the spectra from the floating-reference position and measuring position is proposed to eliminate these spectral variations from background interferences. Its effectiveness was validated by in vitro and in vivo experiments in which the diffuse reflectance of intralipid solutions and human skin was collected at the source distances of 0...

The ability to predict the effects of climatic factors on animals and their adaptability is important for livestock production. The aim of the present study was to analyze whether existing indices are suitable for evaluating heat stress in Santa Ines and Morada Nova sheep, which are locally adapted hair sheep breeds from northeastern Brazil, and if the limits used to classify thermal stress are suitable for these breeds. Therefore, climatic, physiological, and physical parameters, as well as thermographic images, were collected in 26 sheep, 1 1/2 years old, from two genetic groups (Santa Ines 12 males and 4 females; Morada Nov...

The aim of this study is to investigate the effect of particles as filler in soft rubber sensors installed in artificial skin. We examine sensors made of natural rubber (NR-latex) that include magnetic particles of Ni and Fe₃O₄ using magnetic compound fluid (MCF). The 1-mm thickness of the electrolytically polymerized MCF rubber makes production of comparatively thin rubber sensors feasible. We first investigate the effect of magnetic particles Ni and Fe₃O₄ on the curing of MCF rubber. Next, in order to adjust the electric properties of the MCF rubber, we adopt Al₂O₃ dielectric particles...

Burns are a common cause of preventable morbidity and mortality in children. Thermal and chemical burns are the most common types of burns. Their clinical appearance can be similar and the treatment is largely similar. Thermal burns in children occur primarily after exposure to a hot surface or liquid, or contact with fire. Burns are typically classified based on the depth and total body surface area, and the severity and onset of the burn can also depend on the temperature and duration of contact. Chemical burns are caused by chemicals-most commonly acids and alkalis-that can damage the skin on contact...

Sweat is an exacerbation factor in atopic dermatitis (AD) in all age groups. A body core temperature elevation with sweating triggers cholinergic urticaria (CholU). We recently reported that AD symptoms are improved by tannic acid-containing spray, which suppresses the basophil histamine release induced by semi-purified sweat antigen in vitro, and by showering, which removes antigens in sweat from the skin surface. Sweat contains small amount of proteins including proteases, protease inhibitors, and anti-microbial peptides...
