Data on Rapid Desensitization (RD) to ASA is scarce. We aimed to report the outcomes of our 10-year experience with RD to ASA. Methods. Retrospective, observational, single-center study of patients with ASA HS and suspected IHD who underwent RD to ASA between March 2009 and February 2019. Results. Fifty patients were included. ASA HS presentation ranged from urticaria (56%) to anaphylaxis (32%). Regarding cardiologic diagnoses, 40 patients (80%) had acute coronary syndrome and 10 (20%) stable angina. The majority of patients (N = 36.72%) underwent percutaneous coronary intervention. RD to ASA was successful in all patients. Two patients presented a mild HS reaction during the RD, which was promptly treated, and subsequent daily doses of ASA 100 mg were tolerated. Conclusions. In our cohort, RD to ASA in patients with ASA HS and IHD was very effective and safe.<br /><br /> The aim of this study was to evaluate the resilience of girls with central precocious puberty (CPP) during treatment with a gonadotropin-releasing hormone agonist (GnRHa) and compare these results with their healthy peers.<br /><br /> The Connor-Davidson Resilience Scale (CD-RISC) is a self-report scale used to quantify resilience, which is divided into seven subgroups (hardiness, coping, flexibility, purpose, optimism, regulation of emotion and cognition (REC), and self-efficacy). Fifty-one girls with CPP receiving GnRHa treatment and 51 healthy controls were involved in the study. Anthropometric measurements were evaluated and CD-RISC was performed at least six months after the initiation of GnRHa treatment.<br /><br /> There was no statistically significant difference between the anthropometric evaluations of girls with CPP and the control group. Similarly, the total score and subgroup scores of patients with CPP and the control group showed no statistically significant difference. In the correlation analysis, there was a weak negative correlation between height and flexibility (r<br /><br /> p<br /><br /> ), height SDS and flexibility (r<br /><br /> p<br /><br /> ), height SDS, and purpose (r<br /><br /> p<br /><br /> ). Also, there was a weak negative correlation between REC and weight (r<br /><br /> p<br /><br /> ), REC and weight SDS (r<br /><br /> p<br /><br /> )<br /><br /> REC and height (r<br /><br /> p<br /><br /> ), REC and height SDS (r<br /><br /> p<br /><br /> ), REC and BMI (r<br /><br /> p<br /><br /> ), and REC and BMI SDS (r<br /><br /> p<br /><br /> ).<br /><br /> The resilience of girls with CPP treated with GnRHa was found to be similar to their healthy peers. The early diagnosis of the disease and adequate treatment may decrease the discrepancy of somatic changes between girls with CPP and their peers, which may help them to overcome the stress of CPP and long-term treatment.<br /><br />The resilience of girls with CPP treated with GnRHa was found to be similar to their healthy peers.

Preclinical testing allows a wide range of imaging modalities that may be applied both simultaneously and longitudinally, which will in turn lower the number of animals needed to allow a comprehensive assessment of the healing process. This work provides an up-to-date review on morphological, functional, optical, biochemical, and biophysical imaging techniques including their advantages, disadvantages and potential for combining them in a multimodal and multiscale manner. The focus lies on preclinical testing of biomaterials modified with artificial extracellular matrices in various animal models to enhance bone remodeling and regeneration.With rapid urbanization, the increasing building stock, building operation energy consumption and the corresponding carbon emissions have become the important factors restricting the sustainable development of cities. To reduce energy consuming, it is necessary to explore the mechanisms underlying building's operational energy consumption and carbon emission. Although previous studies have analyzed the influencing factors and driving mechanism of urban building carbon emission from different perspectives, a systematical review of the relevant studies which could provide comprehensive guidance for building energy conservation and consumption reduction is fairly scarce. Following the Social-Economic-Natural Complex Ecosystem theory, we comprehensively discussed the driving mechanisms of the building's operational energy consumption and carbon emission. We further analyzed the various single-source driving mechanisms from the perspective of socio-economic, building feature, regional climate and microclimate conditions. Finally, we tackled the weaknesses of current researches and addressed the prospect for future development. The driving mechanism summarized in this work would contribute to the development of related research and support low carbon city construction.Microplastics, a new class of environmental pollutants, accumulates in the environment at an uncontrollable rate, which threatens aquatic organisms. Plankton are the basis of food webs and play a significant role in the material circulation and energy flow of aquatic ecosystems. Plankton are sensitive to various environmental pollutants. It is necessary to investigate the impacts of microplastics on plankton. Here, we analzyed the sources and characteristics of microplastics, and the current state of microplastic pollution in aquatic ecosystem. The direct and indirect harmful effects of microplastics on aquatic organisms were elaborated. Then, we focused on the potential consequences of microplastics on phytoplankton and zooplankton species from different scales, ranging from individual, population, to community level. With respect to plankton organisms, few studies were carried out on genomics and proteomics from the microcosmic perspective, and on popu-lation and community responses from the macroscopic aspect. This review would provide references for further studies.Ecological and environmental problems including heavy metal pollution have received increasing concerns. Given the shortage of physical and chemical remediation methods in high cost and secondary pollution, using plants and microorganisms for joint remediation of environment has become one of the most important strategies. Root exudates are an important medium for information and nutrient exchange between plants and soil. [https://www.selleckchem.com/products/Sunitinib-Malate-(Sutent).html click here] The roles of plant root exudates in remediation of polluted and degradated soil have been widely studied. In this review, we described the composition, secretion mechanism and functions of root exudates and summarized the functions of root exudate in heavy metal absorption, allelopathy, interaction between roots and rhizosphere microorga-nisms, and changes in soil physical and chemical properties. The progress, challenges and prospect of applying root exdudates and rhizosphere microorganisms in the remediation of ecology and environment have also been discussed. This review could provide theoretical support for the application of plant-microorganism based environmental remediation.Quantitative stable isotope probing (qSIP) is a powerful tool, which links microbial taxon with functional metabolism in ecosystems and quantitatively determines the metabolic activity or growth rate of individual microbial taxa exposed to isotope tracers in the environment. qSIP technique employs quantitative PCR, high-throughput sequencing and stable isotope probing (SIP) techniques. The procedure involves adding labeled substrates to environmental samples for cultivation, separating labeled heavy fraction from unlabeled light fraction via isopycnic ultracentrifugation, making absolute quantification and sequencing analysis for microbial populations in all fractions, and then quantifying the isotope abundance of DNA involved in uptake and transformation based on the DNA density curve of unlabeled treatment and GC content. Here, we reviewed the rationale, data analysis and application of qSIP in microbial ecology, and discussed the existing problems and prospects of qSIP.Based on the fishery resource investigation data in Pishan waters of Zhejiang coastal area in November of 2015 (autumn), February (winter), May (spring) and August (summer) of 2016, we analyzed the spatio-temporal niche characteristics and interspecific association of the domi-nant shrimp and crab species using the methods of niche test, variance ratio, chi-square test, Spearman test and redundancy analysis. A total of 34 shrimp and crab species belonging to 14 families and 20 genera were identified. Among them, 10 species were collected in all the four seasons. Dominant species were Parapenaeopsis hardwickii, Exopalaemon carinicauda and Portunus trituberculatus. The temporal, spatial and spatio-temporal niche breadths of the major shrimp and crab species ranged from 0.03-1.34, 2.07-3.63 and 0.08-4.64, respectively. The cluster analysis of niche breadths suggested that all the species could be divided into narrow, medium and wide niche breadth groups under the 90% similarity level. In addition, the spatio-temporal niche overlap values of the major species in Pishan Sea were mainly at low level (68.9% of the species's Qik less then 0.3), implying little interspecific competition for resource utilization. The analysis of variance ratio showed that the major shrimp and crab species were mainly positively correlated, with 11.1% of the species showing significantly positive association. The JI index, OI index and Spearman test all showed the relationship between major shrimp and crab species tended to be positive correlation as a whole. Redundancy analysis showed that surface temperature, bottom temperature, and surface salinity were the main environmental factors affecting the distribution of shrimp and crab species in Pishan waters.Amphibians with a unique life history are extremely sensitive to environmental changes. They are important indicator species for environmental change. The construction of Kaifeng water system affects the habitat and biodiversity of amphibians. In this study, we investigated the amphi-bians in water system of Kaifeng by setting sample points and using visual encounter method, and measured the habitat variables. We quantified amphibian biodiversity under different habitat types using the Shannon diversity index, Pielou evenness index and Simpson dominance index, and explored the responses of amphibians to microhabitat variations by cluster analysis and redundancy analysis. The results showed that the diversity, evenness, and dominance of amphibians in the natural revetment were higher than those in the artificial hardened revetment, indicating a more stable amphibian population in the natural habitat. The dominance index of amphibians on natural revetment was higher than that of the two artificially hardened revetments, indicating that amphibians preferred natural habitat. The abundance of both Palophylax nigromaculata and Bufo gargarizans had significant positive correlation with night light intensity, while the abundance of P. plancyi was positively correlated with total phosphorus, and that of Fejervarya limnocharis was positively correlated with water pH. The protection of amphibians should be considered in the construction of urban water system in Kaifeng. The presence of more natural revetment would be of great significance to enhance amphibian biodiversity.
