Exposure to endocrine disrupting chemicals perturbs lipid metabolism and circadian rhythms

引用

Journal of Environmental Sciences 2017年第12期29卷 133-137页

A growing body of evidence indicates that exposure to environmental chemicals can contribute to the etiology of obesity by inappropriately stimulating adipogenesis as well as perturbing lipid metabolism and energy balance. One potential mechanism by which chemical exposure can influence lipid metabolism is through disturbance of circadian rhythms, endogenously-driven cycles of roughly 24 hr in length that coordinate biochemical, physiological, and behavioral processes in all organisms. Here we show for the first time that exposure to endocrine disrupting compounds（EDCs）, including the pesticide tributyltin, two commercial flame retardants, and a UV-filter chemical found in sunscreens,can perturb both circadian clocks and lipid metabolism in vertebrates. Exposure of developing zebrafish to EDCs affects core clock activity and leads to a remarkable increase in lipid accumulation that is reminiscent of the effects observed for longdaysin, a known disruptor of circadian rhythms. Our data reveal a novel obesogenic mechanism of action for environmental chemicals, an observation which warrants further research. Because circadian clocks regulate a wide variety of physiological processes, identification of environmental chemicals capable of perturbing these systems may provide important insights into the development of environmentally-induced metabolic disease.

AIM： To determine the incidence of cystoid macular edema（CME） after Descemet＇s stripping automated endothelial keratoplasty（DSAEK）.METHODS： This study included all consecutive patients operated in a Spanish tertiary reference hospital over a period of four years. A total of 55 eyes from 47 patients matched the selection criteria. CME was diagnosed clinically at the slit-lamp and confirmed by optical coherence tomography. RESULTS： Six cases of CME were diagnosed postoperatively, which represented an incidence of 11%. Three patients had previously undergone DSAEK alone（7%; 3/41） and the other three, DSAEK combined with phacoemulsification（21%; 3/14）. Five out of six patients with CME responded to standard ***： CME is a possible complication after DSAEK and can be treated with standard therapy. CME appears more frequently when DSAEK is combined with phacoemulsification and posterior chamber（PC） intraocular lens（IOL） implantation. Intraoperative damage to the corneal endothelial cells might play a role in the pathogenesis of CME. As long as the causes remain unclear, we recommend administering prophylaxis when risk factors are present or when combined surgery is planned.

The role of clinical diagnosis criteria on the frequency of accommodative insufficiency

引用

International Journal of Ophthalmology(English edition) 2019年第4期12卷 647-653页

作者： María garcía-Montero Beatriz Antona Ana Rosa Barrio Carmen Nieto-Zayas irene martínez-Alberquilla José Luis Hernández-Verdejo Department of Optometry and Vision Faculty of Optics and Optometry Complutense University of Madrid Department of Statistics and Operations Research Ⅲ Faculty of Statistical Studies Complutense University of Madrid

AIM: To estimate and compare the frequency of accommodative insufficiency(AI) within the same clinical population sample depending on the type of clinical criteria used for diagnosis. Comparing the frequency within the same population would help to minimize bias due to sampling or methodological variability. METHODS: Retrospective study of 205 medical records of symptomatic subjects free of any organic cause and symptoms persisting despite optical compensation evaluated. Based on the most commonly clinical diagnostics criteria found in the literature, four diagnostics criteria were established for AI(Ⅰ, Ⅱ, Ⅲ and Ⅳ) based on subjective accommodative tests: monocular accommodative amplitude two or more diopters below Hofstetter's minimum value [15-(0.25×age)](Ⅰ, Ⅱ, Ⅲ, Ⅳ); failing monocular accommodative facility with minus lens, establishing the cut-off in 0 cycles per minute(cpm)(Ⅰ) and in 6 cpm(Ⅱ, Ⅲ); failing binocular accommodative facility with minus lens, establishing the cut-off in 0 cpm(Ⅰ) and in 3 cpm(Ⅱ).RESULTS: The proportion of AI(95%CⅠ) for criteria Ⅰ, Ⅱ, Ⅲ and Ⅳ were 1.95%(0.04%-3.86%), 2.93%(0.31%-4.57%), 6.34%(1.90%-7.85%) and 41.95%(35.14%-48.76%) respectively, with a statistically significant difference shown between these values(χ2=226.7, P<0.001). A pairwise multiple comparison revealed that the proportion of AI detected for criterion Ⅳ was significantly greater than the proportion for the rest of the criteria(P-adjusted<0.05 in all cases).CONCLUSION: The prevalence of cases of AI within the same clinical population varies with the clinical diagnostic criteria selected. The variation is statistically significant when considering the monocular accommodative amplitude as the only clinical diagnostic sign.

The Construction of Locally D-Optimal Designs by Canonical Forms to an Extension for the Logistic Model

引用

Applied Mathematics 2014年第5期5卷 824-831页

作者： irene garcía Camacha Gutiérrez Raúl martín martín Mathematics Department Castilla-La Mancha University Toledo Spain

Logistic regression models for binary response problems are present in a wide variety of industrial, biological, social and medical experiments;therefore, optimum designs are a valuable tool for experimenters, leading to estimators of parameters with minimum variance. Our interest in this contribution is to provide explicit formulae for the D-optimal designs as a function of the unknown parameters for the logistic model where q is an indicator variable. We have considered an experiment based on the dose-response to a fly insecticide in which males and females respond in different ways, proposed in Atkinson et al. (1995) [1]. To find the D-optimal designs, this problem has been reduced to a canonical form.

The endemic silverside fish C. humboldtianum is of great ichtyologycal, economical and cultural relevance in central Mexico and it has been suggested that it is among a group of other “peces blancos”, the most ancestral species. Here we characterized a set of 26 microsatellite loci from the species in order to further assess population and phylogeographic issues that aid in evaluating their highly impacted populations. From 58 primer pairs tested on specimens from Villa Victoria dam (Rio Balsas Basin), 26 loci positively amplified on the species and cross-primed on specimens of the closely related and threatened Poblana alchichica, C. promelas and C. riojai. Loci resolved medium and high genetic variation (mean NA = 14.3, SD = 9.38;mean HO & HE = 0.47, SD = 0.32 and 0.58, SD = 0.32, respectively) and it is expected that these polymorphic loci are also useful in studing threatened atherinopsid species.
