Indian Scenario

Background: Many people believe that all cosmetics are safe but there are number of studies proving that majority of the cosmetics contains heavy metals or other chemicals. In this study we selected two heavy metals arsenic and lead because as per the Indian scenario is concerned most of the Hindu and Muslim females uses lead/arsenic based cosmetics.Methods: For the qualitative/quantitative estimation to detect heavy metals such as arsenic and lead in cosmetics, 20 different types of cosmetics were purchased from local market, labelled and analysed by qualitative test for heavy metals method and ICP-AES Analysis of cosmetics method.Results: A questionnaire was framed out in English and analysis showed that students had an adverse effect while using cosmetic products. Preliminary analysis of some samples gave positive results and for confirmation these samples were sent to IIT Bombay for ICP-AES analysis. Some of the samples showed variable level of heavy metals such as lead and arsenic. Highest concentration of lead and arsenic was found in Surma followed by Sindoor, lip balm and Kajal.Conclusions: Heavy metals are one of the major contaminant in our eco system. Apart from this a number of cosmetic products also contain the same. Chronic use of this kind of cosmetic products will leads heavy metal toxicity.

Diversos poluentes – tais como: os compostos orgânicos e inorgânicos e metais pesados, resultantes de atividades antrópica – contribuem com a degradação de ambientes terrestres e aquáticos. Nesse cenário, surge a fitorremediação: uma técnica de biorremediação, em que determinadas espécies de plantas são utilizadas como agentes de descontaminação, removendo, imobilizando ou tornando os contaminantes menos ofensivos ao ecossistema. Embora recente, essa técnica tem apresentado respostas positivas concernentes à descontaminação de água e solos. Assim, o presente artigo teve como objetivo relacionar diferentes espécies de plantas com potencial remediador frente a diversos tipos de contaminantes. Para tanto, foi realizada uma revisão da literatura científica nacional e internacional, a partir da busca de estudos disponíveis no Google Acadêmico, PubMed, Portal de Periódicos da CAPES, SciELO, além de livros de referência, dissertações e teses. As publicações analisadas atestaram que, embora seja uma tecnologia ainda em desenvolvimento, são notáveis diversas vantagens da fitorremediação, como o baixo custo de implantação e sua natureza não invasiva. Além disso, pode ser destacado o potencial fitorremediador recentemente descrito para diferentes espécies vegetais.Palavras-chave: Fitorremediação. Descontaminação Ambiental. Metais Pesados.

In this scenario, phytoremediation emerges: a bioremediation technique in which certain plant species are used as decontamination agents, removing, immobilizing or making the contaminants less offensive to the ecosystem. Although recent, this technique has presented positive results concerning the water and soil decontamination. Thus, the present article aimed at relating different plant species with potential to remediate different types of contaminants. For this, a review of the national and international scientific literature was carried out, based on the search of studies available in Google Scholar, PubMed, CAPES Periodicals Portal, SciELO, as well as reference books, dissertations and theses. The analyzed publications show that, although it is a technology still in development, several advantages of phytoremediation are remarkable, such as the low cost of implantation and its noninvasive nature. Moreover, the phytoremediation potential recently described for different plant species can be higlighted.Keywords: Phytoremediation. Environmental Decontamination. Heavy Metals. Herbicides.

Single Center Observational Study

Abstract Background/Aims  During the COVID-19 pandemic, analysis of the incidence of COVID-19 among patients suffering from rheumatic diseases and receiving therapy with biological agents remains relevant. Methods  This single-center observational study included 118 children suffering from various rheumatic diseases and receiving therapy with anti-rheumatic drugs and biological agents. In this research, we analyzed the incidence of CIVID-19 and the frequency of documented contact with SARS-CoV-2 in the period from 01.03.2020 to 11.10.2020 (32 weeks). The results were analyzed using descriptive statistics. Results  Among 118 children, there were 28 (24%) boys and 90 (76%) girls, average age 10.3±4.2. 104 (88.2%) patients had different types of juvenile idiopathic arthritis (JIA), 2 (1.6%) children had systemic lupus erythematosus (SLE), 2 (1.6%) patients had juvenile dermatomyositis (JDM), 1 (1%) child had ANCA-associated vasculitis, 6 (5%) patients had familial Mediterranean fever (FMF), 2 (1.6%) children had deficiency of adenosine deaminase 2 (DADA2), 1 (1%) child had TNF receptor-associated periodic syndrome (TRAPS). In this group of patients 94 (79%) patients were treated with methotrexate, 1 (1%) - azathioprine, 3 (2%) patients received hydroxychloroquine, 6(5%) - mycophenolate mofetil, 4 (3%) - sulfasalazine, 14(11%) children received prednisone, 6(5%) - cyclosporine A. All children included in this study received biological agents for more than 1 year, the distribution of biological agents among patients was as follows: 41(34%) - etanercept, 33(28%) - adalimumab, 24 (20%) - tocilizumab, 7 (6%) - canakinumab, 3 (2%) - abatacept, 4 (3%) - golimumab, 6 (5%) - rituximab. Out of 118 children, 4 (3%) patients had flu-like symptoms and positive results of PCR tests for COVID-19 (1 patient was treated with etanercept, 1 - adalimumab, 1 - tocilizumab, 1 - rituximab), none of the patients had signs of SARS-CoV-2 pneumonia. 10 (8%) patients had documented contact with COVID-19: among this patients 2 children had flu-like symptoms, positive results of PCR tests and absence of COVID-19 pneumonia (one of this patient was treated with adalimumab, another one - with rituximab), one more patient was treated with tocilizumab and had positive PCR test without any symptoms of COVID-19; other 7 children had negative PCR tests and didn’t have any signs of COVID-19. Conclusion  Among our patients with various rheumatic diseases treated with biological agents there were no registered severe cases of COVID-19. Over the past period (32 weeks of follow-up) 3% of children with COVID-19 were identified and 8% patients had documented contact with COVID-19, but we suppose it is too early to make conclusions about the degree and severity of COVID-19 among children suffering from rheumatic diseases and receiving various biological agents. Further follow-up is needed to better understand the risk and impact of COVID-19 among children with rheumatic diseases and receiving therapy with biological agents. Disclosure  N. Tsurikova: None.

Ecotoxicological Bioassay

Lignocellulosic bioethanol production results in huge amounts of stillage, a potentially polluting by-product. Stillage, rich in heavy metals and, mainly, inhibitors, requires specific toxicity studies to be adequately managed. To this purpose, we applied an FTIR ecotoxicological bioassay to evaluate the toxicity of lignocellulosic stillage. Two weak acids and furans, most frequently found in lignocellulosic stillage, have been tested in different mixtures against three Saccharomyces cerevisiae strains. The metabolomic reaction of the test microbes and the mortality induced at various levels of inhibitor concentration showed that the strains are representative of three different types of response. Furthermore, the relationship between concentrations and FTIR synthetic stress indexes has been studied, with the aim of defining a model able to predict the concentrations of inhibitors in stillage, resulting in an optimized predictive model for all the strains. This approach represents a promising tool to support the ecotoxicological management of lignocellulosic stillage.

ABSTRACT A portable, handheld gluten detection device, the Nima sensor, is now available for consumers wishing to determine if gluten is present in food. By U.S. regulation, gluten-free foods should contain <20 ppm of gluten. Thirteen gluten-free foods (muffins, three different types of bread, three different types of pasta, puffed corn snack, ice cream, meatballs, vinegar and oil salad dressing, oatmeal, and dark chocolate) were prepared; each food was spiked on a weight to weight basis with gluten levels of 0, 5, 10, 20, 30, 40, and 100 ppm before processing or preparation. Unprocessed and processed foods were tested with the handheld gluten sensor and by two gluten-specific enzyme-linked immunosorbent assays (ELISAs) on the basis of the R5 and G12 monoclonal antibodies, respectively. The portable gluten detection device detected gluten in all food types at the 30-ppm addition level, failing to detect gluten in only 5 (6.4%) of 78 subsamples. At the 20-ppm addition level, the portable gluten detection device failed to detect gluten in one type of pasta but detected gluten residues in 63 (87.5%) of 72 other subsamples. The device was able to detect gluten at the 10-ppm addition level in 9 of the 13 food matrices (41 of 54 subsamples, 75.9%) but not in the three types of pasta and the puffed corn snack. The gluten-sensing device did not perform reliably at the 5-ppm addition level in 11 of 13 food matrices (exceptions: ice cream and muffins). In contrast, the ELISA methods were highly reliable at gluten addition levels of ≥10 ppm in all food matrices. The portable gluten detection device yielded a low percentage of false-positive results (4 of 111, 3.6%) in these food matrices. Thus, this handheld portable gluten sensor performed reliably in the detection of gluten in foods having ≥20 ppm of added gluten with only 18 (5.9%) of 306 failures, if results of the one type of pasta are excluded. The device worked with greater reliability as the gluten levels in the foods increased.

Everyday Problem

Many plants cause dermatosis in the human population, thus presenting an everyday problem for dermatologists and allergologists around the world. To this day it is still not known how common are plant-induced dermatosis. It is estimated that around 334 million people worldwide, or 3.5% of the world population, is affected by dermatosis each year. The onset of dermatitis is most common in the early childhood. Around 20% of children in Great Britain and 10% in the USA are affected by different types of dermatosis. It is believed that around 10,000 plant species can cause dermatosis in humans. Phytodermatosis are dermatosis caused by plants. They are usually induced by direct contact with a plant, but can also occur without a direct contact or be activated by the sun. Dermatosis which occur without a direct contact with the plant are observed in those cases where certain perfumes, cremes or other cosmetic products are used. Some cosmetic products contain substances such as eugenol, isoeugenol, cinnamaldehyde, colophonium, turpentines and other substances which originate from plants. Similarly, lichens, which are not plants, but organisms resulting from a fungi and algae symbiosis, produce usnic acids, which are most commonly used in sun protection products.
