Insects interact with the surrounding environment via chemoreception, and in social insects such as ants, chemoreception functions to mediate diverse behaviors including food acquisition, self/non-self recognition, and intraspecific communication. The invasive red imported fire ant, Solenopsis invicta, has spread worldwide, displaying a remarkable environmental adaptability. Odorant binding proteins (OBPs) are chemical compound carriers, involved in diverse physiological processes including odor detection and chemical transport...

Background Though iodine deficiency in pregnancy is a matter of public-health concern, a functional measure of iodine status is lacking. The thyroid-specific protein, thyroglobulin (Tg), which reflects thyroid size, has shown promise as a functional measure in studies of children and adults, but data in pregnancy are sparse. In a cohort of mildly-to-moderately iodine-deficient pregnant women, we aimed to explore whether serum Tg is a sensitive functional biomarker of iodine status and to examine longitudinal change in Tg with gestational age...

Introducción: ante las nuevas implicaciones atribuidas a la vitamina D y la asociación con enfermedades tales como el cáncer, diabetes, enfermedades cardiovasculares, autoinmunes y mortalidad, no es de extrañar que se haya defendido la medición de los niveles de vitamina D en la población general. Sin embargo, no existen datos experimentales que demuestren la viabilidad y rentabilidad de la estrategia de cribado en la población y tampoco se ha comprobado la existencia de beneficios para la salud, por lo que en la actualidad solo es aconsejable la medida de 25 (OH) vitamina D en los grupos de personas de alto riesgo como indican las guías clínicas internacionales...

Anthracyclines (ANTs) are powerful drugs that have reduced the mortality of cancer patients. However, their use is limited by the development of cardiotoxicity (CTX), which is dose dependent and may lead to left ventricular dysfunction and heart failure. Although various strategies have been suggested to reduce the negative effects of ANTs, CTX is still an important unresolved clinical issue. This may be due at least partly to the incomplete characterization of the molecular and cellular mechanisms of ANT-induced CTX...

Recent theoretical work suggests that two ineffective control agents can provide effective biological control when coupled together. We explore the implications of this work with the system of coffee leaf rust (CLR), caused by the fungal agent Hemileiae vastatrix, and two of its natural enemies, a fungal pathogen (Lecanicillium lecanii) and a spore predator (Mycodiplosis hemileiae). Here we report on comparative surveys of the CLR and its two natural enemies in Mexico, where the CLR has been at epidemic status since 2012, and Puerto Rico, where the CLR is present but has not reached epidemic densities...

The influence of failure propagation is ignored in failure sample selection based on traditional testability demonstration experiment method. Traditional failure sample selection generally causes the omission of some failures during the selection and this phenomenon could lead to some fearful risks of usage because these failures will lead to serious propagation failures. This paper proposes a new failure sample selection method to solve the problem. First, the method uses a directed graph and ant colony optimization (ACO) to obtain a subsequent failure propagation set (SFPS) based on failure propagation model and then we propose a new failure sample selection method on the basis of the number of SFPS...
