\n\nObjective: This study was aimed
at using the infrared tympanic thermometer (IRTT) in oral mode to measure 123 temperature in febrile and afebrile children less than 5 years.\n\nMethods: Rectal and tympanic temperatures were measured consecutively in 400 febrile and 400 afebrile under-5 children matched for age, GW2580 using the mercury-in-glass thermometer and the IRTT in oral mode respectively.\n\nResults: In the febrile children, the mean tympanic temperature was 38.6 +/- 0.9 degrees C, while the mean rectal temperature was 39.0 +/- 0.8 degrees C. In the afebrile group, the mean tympanic temperature was 37.0 +/- 0.4 degrees C, while the mean rectal temperature was 37.4 +/- 0.3 degrees C. The mean difference between rectal and tympanic temperatures in both groups was statistically significant. There was good correlation between the two temperatures. The tympanic thermometer used in the oral mode had a sensitivity
of 87.3% and a specificity of 96.5%.\n\nConclusion: The IRTT (oral mode) may not be reliable in estimating ‘core’ body temperature in children under the HM781-36B in vitro age of five years, but with a fairly good sensitivity and specificity, as well as its other advantages such as short duration of measurement, convenience and safety, it is a useful instrument for screening children with fever in a busy setup.”
“High-throughput analyses have frequently been used to characterize herbivory-induced reconfigurations in plant primary and secondary metabolism in above- and below-ground tissues, but the conclusions drawn from these analyses are often limited by the univariate methods used to analyze the data. Here we use our previously described multivariate time-series data analysis to evaluate leaf herbivory-elicited transcriptional and metabolic dynamics in the roots of Nicotiana MX69 attenuata. We observed large, but transient, systemic responses in the roots that contrasted with the pattern of co-linearity observed in the up- and downregulation of genes and metabolites across the entire time series
in treated and systemic leaves. Using this newly developed approach for the analysis of whole-plant molecular responses in a time-course multivariate data set, we simultaneously analyzed stress responses in leaves and roots in response to the elicitation of a leaf. We found that transient systemic responses in roots resolved into two principal trends characterized by: (i) an inversion of root-specific semi-diurnal (12h) transcript oscillations and (ii) transcriptional changes with major amplitude effects that translated into a distinct suite of root-specific secondary metabolites (e.g. alkaloids synthesized in the roots of N.attenuata). These findings underscore the importance of understanding tissue-specific stress responses in the correct day-night phase context and provide a holistic framework for the important role played by roots in above-ground stress responses.
