BACKGROUND Malnutrition is a common problem in dialysis patients and may affect up to one-third of patients. Near-infrared interactance (NIR) is a novel approach to estimate body composition and per cent total body fat. METHODS We used near-infrared interactance (Futrex 5000) to estimate the body composition including body fat percentage, as well as subjective global assessment (SGA), anthrop...

BACKGROUND Under-nutrition in neonates is closely linked to low body fat percentage. Undernourished neonates are exposed to immediate mortality as well as unwanted health impacts in their later life including obesity and hypertension. One potential low cost approach for obtaining direct measurements of body fat is near-infrared (NIR) interactance. The aims of this study were to model the effect...

introduction application of near-infrared absorbing nanostructures can induce hyperthermia, in addition to providing more efficient  photothermal effects. gold-gold sulfide (ggs) is considered as one of these nanostructures. this study was performed on a tissue-equivalent optical-thermal phantom to determine the temperature profile in the presence and absence of ggs and millisecond pulses of a ...

Deep near-infrared (NIR) surveys are critical to our current, and even more to our future, understanding of galaxy evolution in the early universe. In this review I will be discussing the relevance of deep NIR surveys and looking at the information provided by different types of survey: broad-band imaging, spectroscopic observations and narrow-band imaging. In particular I will be looking at th...

OBJECTIVE In ovarian cancer, two of the most important prognostic factors for survival are completeness of staging and completeness of cytoreductive surgery. Therefore, intra-operative visualization of tumor lesions is of great importance. Preclinical data already demonstrated tumor visualization in a mouse-model using near-infrared (NIR) fluorescence imaging and indocyanine green (ICG) as a re...

Response 4: The introduction will be changed to contain: Sussmann et al. 2013 did a similar study on the inter-comparison of methane from MIR and NIR retrievals. They used a Tikhonov-L1 regularized profile retrieval scheme with the standard NDACC retrieval package SFIT2 for the MIR and the standard TCCON retrieval (GFIT) for the NIR spectra. They conclude that the obtainable information from th...

In this paper, we report a highly selective and sensitive ratiometric NIR fluorescent probe that can be used for real-time detection of the biologically important hypochlorite with colorimetric and significant NIR fluorescent turn-on signal changes at NIR excitation wavelength. In addition, experiments showed that this probe can be applied to detect hypochlorite in tap water, serum samples, and...
