Qualitative information on the spatial distribution from the chemical images was combined with quantitative information on the peak shift to evaluate the different manufacture (lead carbonate, basic lead carbonate) or the extent of decay undergone by the lead-based pigments as a function of their grain size, contiguous layers, and moisture source. Similar results, having a high impact on heritage science and analytical chemistry, allow developing up-to-date conservation strategies by connecting an advanced knowledge of the materials to the social and conservation history of artefacts.Circular RNAs (circRNAs) have gained attention due to their performance in disease diagnosis. However, the characteristics of circRNAs in peripheral blood from patients with systemic lupus erythematosus (SLE) remain unknown. Therefore, the aim of the present study was to determine the expression profile and diagnostic potential of circRNAs in peripheral blood from patients with SLE. The global circRNA expression in the peripheral blood of patients with SLE and healthy controls (HCs) was detected using a circRNA microarray. Then, the expression levels of three upregulated circRNAs were selected for further validation by reverse transcription‑quantitative PCR (RT‑qPCR) in a training set. Moreover, the diagnostic value of these circRNAs was assessed by constructing a receiver operating characteristic curve, and then verified in a blind testing set. In total, 1,566 circRNAs were identified to be dysregulated between patients with SLE and HCs (≥2 fold change, P less then 0.05). Furthermore, the RT‑qPCR results wersease activity index. In conclusion, the expression levels of hsa_circ_0082688‑hsa_circ_0082689 may serve as potential biomarkers for SLE diagnosis.Deleting the gene for small RNA GcvB in Esherichia coli was found to increase the sensitivity to several aminoglycoside antibiotics, such as neomycin, streptomycin, kanamycin, kasugamycin and spectinomycin, at low concentrations. GcvB, conserved in gram-negative enteric bacteria, is known to negatively control the expression of many genes for amino acid incorporation systems, especially the periplasmic ABC-transporter proteins. Deletions of several amino acid transporter genes in ΔgcvB cells decreased the antibiotic sensitivity to the wild type level, suggesting that those genes are involved in uptake of aminoglycosides into the cell. Since GcvB is constitutively synthesized in growing cells, repressing synthesis of amino acid transporters, it contributes to the intrinsic resistance to several aminogycoside antibiotics.
  To stop the spread of the new coronavirus disease in 2019 (COVID-19), many countries had completely locked down. This lockdown restricted the everyday life of the affected residents and changed their mobility pattern, but its effects on sleep pattern were largely unknown.
 
  Here, utilizing one of the largest crowdsourced database (Sleep as Android), we analyzed the sleep pattern of 25217 users with 1352513 sleep records between 1 January and 29 April 2020 in the US and 16 European countries (Germany, UK, Spain, France, Italy, The Netherlands, Belgium, Hungary, Denmark, Finland, Norway, Czech, Sweden, Austria, Poland and Switzerland) with more than 100 records in all days of 2020.
 
  During the COVID-19 pandemic, the sleeping pattern before and after the country-level lockdown largely differed. The subjects increased their sleep duration by an average of 11.3 to 18.6 min on weekday nights, except Denmark (4.9 min) and Finland (7.1 min). In addition, subjects form all 16 European countries delayed their sleep onset from 10.7 min (Sweden) to 29.6 min (Austria).
 
  During the COVID-19 pandemic, residents in the US and 16 European countries delayed their bedtime and slept longer than usual.

  Many health conditions are associated with stigma due to beliefs about their causes and the physical changes experienced by patients. Among such conditions are several neglected tropical diseases (NTDs). Podoconiosis, classified as an NTD, is a form of lymphoedema caused by the co-influence of genetic and environmental factors. It is a major public health problem in Ethiopia and is associated with intense stigma. Despite this, little is known about the factors contributing to stigmatizing attitudes against patients with the disease.
 
  A cross-sectional survey was conducted in southern Ethiopia to analyse the attitudes of rural youth and associated risk factors for stigmatizing attitudes towards patients with podoconiosis, with the aim of informing stigma reduction strategies.
 
  The survey included 336 randomly selected youth. Of the 177 (52.7%) youth who held more stigmatizing attitudes toward patients with podoconiosis, 105 (59.3%) were females and 171 (96.6%) did not have affected friends. Accurate knowledge about gene-environment influences and rejection of infectious causes of podoconiosis were associated with less stigmatizing attitudes.
 
  Improving understanding of the gene-environment interaction and dispelling beliefs about infectious causes may reduce negative attitudes about podoconiosis. Affected youth may play an important role as agents of change to spread non-stigmatizing messages.

It is caused by barefoot exposure to soils and affects disadvantaged populations. Evidence from the past 5 y suggests that podoconiosis is amenable to public health interventions, e.g. footwear and hygiene-based morbidity management, which reduce acute clinical episodes. Although much has been learned in recent years, advances in care for these patients and worldwide control requires further reliable and relevant research. To develop a comprehensive global control strategy, the following key research priorities are important better understanding of the global burden of podoconiosis through extended worldwide mapping, development of new point-of-care diagnostic methods and approaches to define the presence of the environmental characteristics that contribute to the development of the condition, improving treatment through an increased understanding of the pathogenesis of dermal changes over time, improved understanding of optimal ways of providing patient care at the national level, including research to optimize behavioural change strategies, determine the optimum package of care and integrate approaches to deliver robust surveillance, monitoring and evaluation of control programmes.
