OBJECTIVES We investigated the association between outdoor air pollutants exposure in the first trimester of pregnancy, and growth and cardio-metabolic risk at four years of age, and evaluated the mediating role of birth weight. METHODS We included mother-child pairs (N&nbsp;=&nbsp;1,724) from the Spanish INMA birth cohort established in 2003-2008. First trimester of pregnancy nitrogen dioxide (NO2) and fine particles (PM2.5) exposure levels were estimated. Height, weight, waist circumference, blood pressure, and lipids were measured at four years of age. Body mass index (BMI) trajectories from birth to four years were identified. RESULTS Increased PM2.5 exposure in the first trimester of pregnancy was associated with decreased z-scores of weight (zWeight) and BMI (zBMI) (zWeight change per interquartile range increase in PM2.5 exposure&nbsp;=&nbsp;-0.12; 95% CI -0.23, -0.01; zBMI change&nbsp;=&nbsp;-0.12; 95% CI -0.23, -0.01). Higher NO2 and PM2.5 exposure was associated to a reduced risk of being in a trajectory with accelerated BMI gain, compared to children with the average trajectory. Birth weight partially mediated the association between PM2.5 and zWeight and zBMI. PM2.5 and NO2 were not associated with the other cardio-metabolic risk factors. CONCLUSIONS This comprehensive study of many growth and cardio-metabolic risk related outcomes suggests that air pollution exposure during pregnancy may be associated with delays in physical growth in the early years after birth. These findings imply that pregnancy exposure to air pollutants has a lasting effect on growth after birth and require follow-up at later child ages. There have been many attempts to explain consciousness, ranging from Plato's archetypes, to Descartes' 'Mind-Body Dualism', and more recently to Chalmers' Qualia, and Andy Clarke's extended mind. Yet none of these conceptualizations of consciousness provide empiric evidence for what consciousness actually constitutes. The present hypothesis is that Consciousness is a product of the Singularity/Big Bang resulting from the endogenization of factors in the environment that have formed our physiology. Understanding the origin of consciousness as the Consciousness of the Singularity/Big Bang requires that it diachronically cuts across space-time. Consciousness functions based on the same data operating system as Cosmology. We can transcend consciousness and approach Consciousness by authoring our own software once we recognize this fundamental, mechanistic interrelationship. Considering the side effects of etomidate, it requires additional anesthetics to reduce the side effects and improve efficacy. Ketamine is often used as an adjunct anesthetic. We hypothesized that etomidate combined with fentanyl was more effective than etomidate combined with ketamine in the anesthesia of pediatric strabotomy. To prove our hypothesis, a prospective randomized controlled clinical study was performed, in which 35 children with strabotomy received etomidate plus ketamine (group A) for anesthesia induction and maintenance and 35 children with strabotomy received etomidate combined with fentanyl (group B). Mean arterial pressure (MAP), heart rate (HR), bispectral index (BIS), anesthesia effect, and emergence agitation and pain were observed before anesthesia induction (T1), after anesthesia induction (T2), at the beginning of the operation (T3), after 10-min operation (T4), and at the end of the operation (T5). Children in group B had significantly lower MAP and HR from T3 to T5, decreased BIS from T2 to T4, better anesthesia effect, and smaller emergence agitation and pain scores at 10&nbsp;min after entering into postanesthesia care unit (PACU) compared with group A (p&nbsp; less then &nbsp;0.05). The mean emergence agitation score in group B was significantly lower than that in group A when the maximum emergence in group B was at 20&nbsp;min after entering into PACU (p&nbsp; less then &nbsp;0.05). In conclusion, etomidate combined with fentanyl plays a good efficacy in anesthesia of pediatric strabotomy compared with etomidate plus ketamine. The human papillomavirus (HPV) is one of the main sexually transmitted pathogens that infect the anogenital epithelium and mucous membranes. HPV genotypes can be classified as high and low oncogenic risk, with infection by the former resulting in cervical cancer in approximately 100 % of the cases. In this work, we developed an ultrasensitive electrochemical biosensor for the detection and identification of different HPV genotypes. A nanostructured platform based on a matrix of polyaniline (PANI) containing gold nanoparticles (AuNps) was designed for the chemical immobilization of a DNA probe capable of recognizing different HPV types. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and atomic force microscopy (AFM) were used to characterize the genosensor. The impedimetric responses indicate that the proposed sensor was able to detect HPV (types 6, 11, 16, 31, 33, 45, and 58) in cervical specimens (cDNA samples). We obtained different profiles of electrochemical responses for the high and low-risk HPV genotypes. By adopting a three-dimensional quantitative analysis of impedance response variables, it was possible to identify the existence of a pattern of association for samples of high oncogenic risk, which may lead to the differential diagnosis of HPV. The biosensor demonstrated an excellent analytical performance for the detection of HPV genotypes with high sensibility and selectivity. The genosensor exhibited a linear range of response in the 1 pg μL-1 to 100 pg μL-1 range. Besides, a limit of detection (LOD) of 2.74 pg μL-1 and 7.43 pg μL-1 was obtained for HPV11 and HPV16, respectively, with regression coefficients of 99.88 % and 99.47 %. Thus, the proposed sensor may serve as a good prognostic indicator for patients infected with papillomavirus. Powdered Poppy Capsule Extractive (PPCE) is largely used as a raw material of Compound Liquorice Tablets, but there are few studies of its quality evaluation or control. In this paper, a novel strategy for quality assessment of PPCE, systematic quantified fingerprint method (SQFM) combined with quantitative analysis of multi-components by a single marker (QAMS) method, was developed and validated. [https://www.selleckchem.com/products/LBH-589.html Panobinostat] According to the outcome of Pm and the content of codeine and morphine, 41 batches of PPCEs were classified into two classifications by hierarchical cluster analysis, and the samples in one of the categories were obviously inferior to normal in quality. The results demonstrated that the strategy developed in this paper could provide a new method for quality evaluation of PPCE or even other traditional Chinese medicine (TCM).
