Taxonomical notes on Brontostoma doughertyae Gil-Santana, Lopes, Marques & Jurberg, 2005 are provided. Photographs of the holotypes of Brontostoma bahiensis, Brontostoma diringshofeni Gil-Santana & Baena, 2009 and Brontostoma doughertyae are presented.
Populations are often divided categorically into distinct racial/ethnic groups based on social rather than biological constructs. Genetic ancestry has been suggested as an alternative to this ...categorization. Herein, we typed over 450,000 CpG sites in whole blood of 573 individuals of diverse Hispanic origin who also had high-density genotype data. We found that both self-identified ethnicity and genetically determined ancestry were each significantly associated with methylation levels at 916 and 194 CpGs, respectively, and that shared genomic ancestry accounted for a median of 75.7% (IQR 45.8% to 92%) of the variance in methylation associated with ethnicity. There was a significant enrichment (p=4.2×10
) of ethnicity-associated sites amongst loci previously associated environmental exposures, particularly maternal smoking during pregnancy. We conclude that differential methylation between ethnic groups is partially explained by the shared genetic ancestry but that environmental factors not captured by ancestry significantly contribute to variation in methylation.
Various genera and species of Harpactorinae (Hemiptera: Heteroptera: Reduviidae: Harpactorinae: Apiomerini and Harpactorini) occurring in French Guiana are treated. Diarthrotarsus guianensis sp. nov. ...(Harpactorini) is described. An updated key to the species of Diarthrotarsus Bergroth, 1905 is presented. Apiomerus nitidicollis Stl, 1872 and Sphodrolestes vittaticollis Stl, 1867 (both Apiomerini), Graptocleptes formosus Miller, 1951, Heza aurantia Maldonado, 1976, Heza phthinica Swanson, 2021, Isocondylus elongatus (Lepeletier Serville, 1825), Notocyrtus costai Gil-Santana Forero, 2009, Notocyrtus depressus Stl, 1872, Notocyrtus tibanae Costa Gil-Santana, 2001 and Ploeogaster gesana Kirkaldy, 1909 (all Harpactorini) are recorded from French Guiana for the first time. The presence of Calliclopius nigripes (Linnaeus, 1767) (Apiomerini) and Heza sericans Stl, 1859 (Harpactorini) in French Guiana is confirmed. Photographs of the specimens studied are presented, with short taxonomical notes on all the recorded species. An illustrated redescription of the male genitalia of Notocyrtus tibanae is given.
Food waste produced in homes represents the largest fraction of food waste generated along the food chain. Therefore, adequate prevention measures based on the quantitative and qualitative dimensions ...of the problem need to be put in place to reduce waste. The objective of the review was to identify areas of interest in relation to the food waste in households, considering the family unit as a whole as well as individual family members. Quantifying the problem is an important aspect in order to know its scope and dimension, but prevention also involves knowing the causes in a home. This is a complex issue, which, on a family level, is related to socioeconomic status, educational level, composition and number of members of the household as well as culinary and buying food habits. Individual variables such as age, sex, values, awareness, lifestyle and time spent on food preparation were included to characterize consumers. The focus of the problem is also important because most consumers consider food waste from a social perspective, without being aware of the serious environmental and economic problems. Habits and customs of consumers are considered the leading cause of food waste in homes and knowledge of this issue raises consumer awareness as a preventive tool.
This paper describes the deployment and experimentation architecture of the Internet of Things experimentation facility being deployed at Santander city. The facility is implemented within the ...SmartSantander project, one of the projects of the Future Internet Research and Experimentation initiative of the European Commission and represents a unique in the world city-scale experimental research facility. Additionally, this facility supports typical applications and services of a smart city. Tangible results are expected to influence the definition and specification of Future Internet architecture design from viewpoints of Internet of Things and Internet of Services. The facility comprises a large number of Internet of Things devices deployed in several urban scenarios which will be federated into a single testbed. In this paper the deployment being carried out at the main location, namely Santander city, is described. Besides presenting the current deployment, in this article the main insights in terms of the architectural design of a large-scale IoT testbed are presented as well. Furthermore, solutions adopted for implementation of the different components addressing the required testbed functionalities are also sketched out. The IoT experimentation facility described in this paper is conceived to provide a suitable platform for large scale experimentation and evaluation of IoT concepts under real-life conditions.
The high PET consume, mainly as bottles, associated with rapid disposal and high resistance to ambient conditions and biological degradation lead to accumulation in the enviromental, constituting a ...worrying scenario in world level. Chemical recycle PET by glycolysis is an important alternative, once bis(hydroxiethyl)terephthalate (BHET), high added value monomer, can be obtained. In this context, this study approaches the use of titanate nanotubes (
i.e
. sodium/protonated titanate nanotubes) as catalyst for PET glycolysis. Reactional conditions, the origin and granulometry of PET flakes were evaluated (at 196 °C). Best results (BHET yield > 80%) were obtained for both catalyst in 3 h of reaction. The protonated titanate nanotubes catalyst were more efficient than sodium titanate nanotubes due to greater concentration of Brönsted and Lewis acid sites, indicated by TPD analyzes.
Graphical Abstract
Independent replication of genetic associations in complex diseases, particularly in whole-genome association studies, is critical to confirm the association.
A whole-genome association study ...identified ORMDL3 as a promising candidate gene for asthma in white populations. Here, we attempted to confirm the role of ORMDL3 genetic variants in asthma in three ethnically diverse populations: Mexican, Puerto Rican, and African American.
We used family-based analyses to test for association between seven candidate single-nucleotide polymorphisms (SNPs) in and around the ORMDL3 gene and asthma and related phenotypes in 701 Puerto Rican and Mexican parent-child trios. We also evaluated these seven SNPs and an additional ORMDL3 SNP in 264 African American subjects with asthma and 176 healthy control subjects.
We found significant associations between two SNPs within ORMDL3 (rs4378650 and rs12603332) and asthma in Mexicans and African Americans (P = 0.028 and 0.001 for rs4378650 and P = 0.021 and 0.001 for rs12603332, respectively), and a trend toward association in Puerto Ricans (P = 0.076 and 0.080 for SNPs rs4378650 and rs12603332, respectively). These associations became stronger among Mexican and Puerto Rican subjects with asthma with IgE levels greater than 100 IU/ml. We did not find any association between ORMDL3 SNPs and baseline lung function or response to the bronchodilator albuterol.
Our results confirm that the ORMDL3 locus is a risk factor for asthma in ethnically diverse populations. However, inconsistent SNP-level results suggest that further studies will be needed to determine the mechanism by which ORMDL3 predisposes to asthma.

The food industry is considered to be one of the greatest sources of environmental contamination produced by dyes. Moreover, a large number of commercial food dyes and their by-products have been ...shown to be toxic, having chronic effects on human health. The search for efficient processes with which to treat these compounds is, therefore, necessary. In this work, the photo-peroxidation and photo-Fenton processes using UV-C and sunlight radiations were evaluated in order to degrade two synthetic dyes commonly found in food industry wastewater, sunset yellow and tartrazine, in an aqueous mixture. The preliminary results showed that the photo-Fenton/UV-C system was the most efficient. The ANOVA analysis results indicated a good fit of the model. The higher degradations were obtained using 50 mg L

of Fe, a pH of 3.5, and a lower surface area/volume ratio (0.02 cm

). In the kinetic study, a good fit was found for the kinetic model proposed by Chan and Chu. Degradations higher than 99% and 78% were obtained for the chromophore and aromatic groups, respectively, in 180 min. Toxicity tests showed that post-treatment samples did not interfere in the development of
Lactuca sativa
seeds and
Escherichia coli
and
Salmonella enteritidis
bacteria strains. The photo-Fenton/UV-C system can, therefore, be considered an efficient treatment for the degradation of the mixture of sunset yellow and tartrazine dyes under the conditions evaluated.
