- Abstract
Splicing generates mature transcripts from genes in pieces in eukaryotic cells. Overwhelming evidence has accumulated that alternative routes in splicing are possible for most human and mammalian genes, thereby allowing formation of different transcripts from one gene. No function has been assigned to the majority of identified alternative splice forms, and it has been assumed that they compose inert or tolerated waste from aberrant or noisy splicing. Here we demonstrate that five human transcription units (WT1, NOD2, GNAS, RABL2A, RABL2B) have constant splice-isoform ratios in genetically diverse lymphoblastoid cell lines independent of the type of alternative splicing (exon skipping, alternative donor/acceptor, tandem splice sites) and gene expression level. Even splice events that create premature stop codons and potentially trigger nonsense-mediated mRNA decay are found at constant fractions. The analyzed alternative splicing events were qualitatively but not quantitatively conserved in corresponding chimpanzee cell lines. Additionally, subtle splicing at tandem acceptor splice sites (GNAS, RABL2A/B) was highly constrained and strongly depends on the upstream donor sequence content. These results also demonstrate that unusual and unproductive splice variants are produced in a regulated manner.

- Abstract
Pheochromocytomas and abdominal paragangliomas are adrenal and extra-adrenal catecholamine-producing tumours. They arise due to heritable cancer syndromes, or more frequently occur sporadically due to an unknown genetic cause. The majority of cases are benign, but malignant tumours are observed. Previous comparative genomic hybridization (CGH) and loss of heterozygosity studies have shown frequent deletions of chromosome arms 1p, 3q and 22q in pheochromocytomas. We applied high-resolution whole-genome array CGH on 53 benign and malignant pheochromocytomas and paragangliomas to narrow down candidate regions as well as to identify chromosomal alterations more specific to malignant tumours. Minimal overlapping regions (MORs) were identified on 16 chromosomes, with the most frequent MORs of deletion (> or = 32%) occurring on chromosome arms 1p, 3q, 11p/q, 17p and 22q, while the chromosome arms 1q, 7p, 12q and 19p harboured the most common MORs of gain (> or = 14%). The most frequent MORs (61-75%) in the pheochromocytomas were identified at 1p, and the four regions of common losses encompassed 1p36, 1p32-31, 1p22-21 and 1p13. Tumours that did not show 1p loss generally demonstrated aberrations on chromosome 11. Gain of chromosomal material was significantly more frequent among the malignant cases. Moreover, gain at 19q, trisomy 12 and loss at 11q were positively associated with malignant pheochromocytomas, while 1q gain was commonly observed in the malignant paragangliomas. Our study revealed novel and narrow recurrent chromosomal regions of loss and gain at several autosomes, a prerequisite for identifying candidate tumour suppressor genes and oncogenes involved in the development of adrenal and extra-adrenal catecholamine-producing tumours.

- Abstract
Breast cancer is a major cause of morbidity and mortality in women and its metastatic spread is the principal reason behind the fatal outcome. Metastasis-related research of breast cancer is however underdeveloped when compared with the abundant literature on primary tumors. We applied an unexplored approach comparing at high resolution the genomic profiles of primary tumors and synchronous axillary lymph node metastases from 13 patients with breast cancer. Overall, primary tumors displayed 20% higher number of aberrations than metastases. In all but two patients, we detected in total 157 statistically significant differences between primary lesions and matched metastases. We further observed differences that can be linked to metastatic disease and there was also an overlapping pattern of changes between different patients. Many of the differences described here have been previously linked to poor patient survival, suggesting that this is a viable approach toward finding biomarkers for disease progression and definition of new targets useful for development of anticancer drugs. Frequent genetic differences between primary tumors and metastases in breast cancer also question, at least to some extent, the role of primary tumors as a surrogate subject of study for the systemic disease.

- Abstract
Glioblastomas (GBs) are malignant CNS tumors often associated with devastating symptoms. Patients with GB have a very poor prognosis, and despite treatment, most of them die within 12 months from diagnosis. Several pathways, such as the RAS, tumor protein 53 (TP53), and phosphoinositide kinase 3 (PIK3) pathways, as well as the cell cycle control pathway, have been identified to be disrupted in this tumor. However, emerging data suggest that these aberrations represent only a fraction of the genetic changes involved in gliomagenesis. In this study, we have applied a 32K clone-based genomic array, covering 99% of the current assembly of the human genome, to the detailed genetic profiling of a set of 78 GBs. Complex patterns of aberrations, including high and narrow copy number amplicons, as well as a number of homozygously deleted loci, were identified. Amplicons that varied both in number (three on average) and in size (1.4 Mb on average) were frequently detected (81% of the samples). The loci encompassed not only previously reported oncogenes (EGFR, PDGFRA, MDM2, and CDK4) but also numerous novel oncogenes as GRB10, MKLN1, PPARGC1A, HGF, NAV3, CNTN1, SYT1, and ADAMTSL3. BNC2, PTPLAD2, and PTPRE, on the other hand, represent novel candidate tumor suppressor genes encompassed within homozygously deleted loci. Many of these genes are already linked to several forms of cancer; others represent new candidate genes that may serve as prognostic markers or even as therapeutic targets in the future. The large individual variation observed between the samples demonstrates the underlying complexity of the disease and strengthens the demand for an individualized therapy based on the genetic profile of the patient.

- Abstract
Neurofibromatosis Type I (NF1) is an autosomal dominant disorder characterized by the development of both benign and malignant tumors. The lifetime risk for developing a malignant peripheral nerve sheath tumor (MPNST) in NF1 patients is approximately 10% with poor survival rates. To date, the molecular basis of MPNST development remains unclear. Here, we report the first genome-wide and high-resolution analysis of DNA copy number alterations in MPNST using the 32K bacterial artificial chromosome microarray on a series of 24 MPNSTs and three neurofibroma samples. In the benign neurofibromas, apart from loss of one copy of the NF1 gene and copy number polymorphisms, no other changes were found. The profiles of malignant samples, however, revealed specific loss of chromosomal regions including 1p35-33, 1p21, 9p21.3, 10q25, 11q22-23, 17q11, and 20p12.2 as well as gain of 1q25, 3p26, 3q13, 5p12, 5q11.2-q14, 5q21-23, 5q31-33, 6p23-p21, 6p12, 6q15, 6q23-q24, 7p22, 7p14-p13, 7q21, 7q36, 8q22-q24, 14q22, and 17q21-q25. Copy number gains were more frequent than deletions in the MPNST samples (62% vs. 38%). The genes resident within common regions of gain were NEDL1 (7p14), AP3B1 (5q14.1), and CUL1 (7q36.1) and these were identified in >63% MPNSTs. The most frequently deleted locus encompassed CDKN2A, CDKN2B, and MTAP genes on 9p21.3 (33% cases). These genes have previously been implicated in other cancer conditions and therefore, should be considered for their therapeutic, prognostic, and diagnostic relevance in NF1 tumorigenesis.

- Abstract
BACKGROUND: DNA methylation is a major epigenetic modification important for regulating gene expression and suppressing spurious transcription. Most methods to scan the genome in different tissues for differentially methylated sites have focused on the methylation of CpGs in CpG islands, which are concentrations of CpGs often associated with gene promoters. RESULTS: Here, we use a methylation profiling strategy that is predominantly responsive to methylation differences outside of CpG islands. The method compares the yield from two samples of size-selected fragments generated by a methylation-sensitive restriction enzyme. We then profile nine different normal tissues from two human donors relative to spleen using a custom array of genomic clones covering the euchromatic portion of human chromosome 1 and representing 8% of the human genome. We observe gross regional differences in methylation states across chromosome 1 between tissues from the same individual, with the most striking differences detected in the comparison of cerebellum and spleen. Profiles of the same tissue from different donors are strikingly similar, as are the profiles of different lobes of the brain. Comparing our results with published gene expression levels, we find that clones exhibiting extreme ratios reflecting low relative methylation are statistically enriched for genes with high expression ratios, and vice versa, in most pairs of tissues examined. CONCLUSION: The varied patterns of methylation differences detected between tissues by our methylation profiling method reinforce the potential functional significance of regional differences in methylation levels outside of CpG islands.

- Abstract
The exploration of copy-number variation (CNV), notably of somatic cells, is an understudied aspect of genome biology. Any differences in the genetic makeup between twins derived from the same zygote represent an irrefutable example of somatic mosaicism. We studied 19 pairs of monozygotic twins with either concordant or discordant phenotype by using two platforms for genome-wide CNV analyses and showed that CNVs exist within pairs in both groups. These findings have an impact on our views of genotypic and phenotypic diversity in monozygotic twins and suggest that CNV analysis in phenotypically discordant monozygotic twins may provide a powerful tool for identifying disease-predisposition loci. Our results also imply that caution should be exercised when interpreting disease causality of de novo CNVs found in patients based on analysis of a single tissue in routine disease-related DNA diagnostics.

- Abstract
To further explore the extent of structural large-scale variation in the human genome, we assessed copy number variations (CNVs) in a series of 71 healthy subjects from three ethnic groups. CNVs were analyzed using comparative genomic hybridization (CGH) to a BAC array covering the human genome, using DNA extracted from peripheral blood, thus avoiding any culture-induced rearrangements. By applying a newly developed computational algorithm based on Hidden Markov modeling, we identified 1,078 autosomal CNVs, including at least two neighboring/overlapping BACs, which represent 315 distinct regions. The average size of the sequence polymorphisms was approximately 350 kb and involved in total approximately 117 Mb or approximately 3.5% of the genome. Gains were about four times more common than deletions, and segmental duplications (SDs) were overrepresented, especially in larger deletion variants. This strengthens the notion that SDs often define hotspots of chromosomal rearrangements. Over 60% of the identified autosomal rearrangements match previously reported CNVs, recognized with various platforms. However, results from chromosome X do not agree well with the previously annotated CNVs. Furthermore, data from single BACs deviating in copy number suggest that our above estimate of total variation is conservative. This report contributes to the establishment of the common baseline for CNV, which is an important resource in human genetics., De två (2) sista författarna delar sistaförfattarskapet.

- Abstract
Background: Segmental duplications flanking the neurofibromatosis type 1 ( NF1) genelocus on 17q11 mediate most gene deletions in NF1 patients. However, the large size of the gene and the complexity of the locus architecture pose difficulties in deletion analysis. We report theconstruction and application of the first NF1 locus specific microarray, covering 2.24 Mb of 17q11,using a non- redundant approach for array design. The average resolution of analysis for the array is similar to 12 kb per measurement point with an increased average resolution of 6.4 kb for the NF1gene. Methods: We performed a comprehensive array- CGH analysis of 161 NF1 derived samples and identified heterozygous deletions of various sizes in 39 cases. The typical deletion was identified in26 cases, whereas 13 samples showed atypical deletion profiles. Results: The size of the atypical deletions, contained within the segment covered by the array, ranged from 6 kb to 1.6 Mb and their breakpoints could be accurately determined. Moreover, 10 atypical deletions were observed to share a common breakpoint either on the proximal or distal end of thedeletion. The deletions identified by array- CGH were independently confirmed using multiplex ligation- dependent probe amplification. Bioinformatic analysis of the entire locus identified 33segmental duplications. Conclusions: We show that at least one of these segmental duplications, which borders the proximal breakpoint located within the NF1 intron 1 in five atypical deletions, might represent a novel hot spot for deletions. Our array constitutes a novel and reliable tool offering significantly improved diagnostics for this common disorder.

- Abstract
A previously detected copy number polymorphism (Ep CNP) in patients affected with neuroectodermal tumors led us to investigate its frequency and length in the normal population. For this purpose, a program called Sequence Allocator was developed and applied for the construction of an array that consisted of unique and duplicated fragments, allowing the assessment of copy number variation within regions of segmental duplications. The average resolution of this array was 11 kb and we determined the size of the Ep CNP to be 290 kb. Analysis of normal controls identified 7.7 and 7.1% gains in peripheral blood and lymphoblastoid cell line (LCL) DNA, respectively, while deletions were found only in the LCL group (7.1%). This array platform allows the detection of DNA copy number variation within regions of pronounced genomic complexity, which constitutes an improvement over available technologies.

- Abstract
Meningiomas are common neoplasms of the meninges lining of the central nervous system. Deletions of 1p have been established as important for the initiation and/or progression of meningioma. The rationale of this array-CGH study was to characterize copy number imbalances of chromosome 1 in meningioma, using a full-coverage genomic microarray containing 2,118 distinct measurement points. In total, 82 meningiomas were analyzed, making this the most detailed analysis of chromosome 1 in a comprehensive series of tumors. We detected a broad range of aberrations, such as deletions and/or gains of various sizes. Deletions were the predominant finding and ranged from monosomy to a 3.5-Mb terminal 1p homozygous deletion. Although multiple aberrations were observed across chromosome 1, every meningioma in which imbalances were detected harbored 1p deletions. Tumor heterogeneity was also observed in three recurrent meningiomas, which most likely reflects a progressive loss of chromosomal segments at different stages of tumor development. The distribution of aberrations supports the existence of at least four candidate loci on chromosome 1, which are important for meningioma tumorigenesis. In one of these regions, our results already allow the analysis of a number of candidate genes. In a large series of cases, we observed an association between the presence of segmental duplications and deletion breakpoints, which suggests their role in the generation of these tumor-specific aberrations. As 1p is the site of the genome most frequently affected by tumor-specific aberrations, our results indicate loci of general importance for cancer development and progression.

- Abstract
We have constructed the first comprehensive microarray representing a human chromosome for analysis of DNA copy number variation. This chromosome 22 array covers 34.7 Mb, representing 1.1% of the genome, with an average resolution of 75 kb. To demonstrate the utility of the array, we have applied it to profile acral melanoma, dermatofibrosarcoma, DiGeorge syndrome and neurofibromatosis 2. We accurately diagnosed homozygous/heterozygous deletions, amplifications/gains, IGLV/IGLC locus instability, and breakpoints of an imbalanced translocation. We further identified the 14-3-3 eta isoform as a candidate tumor suppressor in glioblastoma. Two significant methodological advances in array construction were also developed and validated. These include a strictly sequence defined, repeat-free, and non-redundant strategy for array preparation. This approach allows an increase in array resolution and analysis of any locus; disregarding common repeats, genomic clone availability and sequence redundancy. In addition, we report that the application of phi29 DNA polymerase is advantageous in microarray preparation. A broad spectrum of issues in medical research and diagnostics can be approached using the array. This well annotated and gene-rich autosome contains numerous uncharacterized disease genes. It is therefore crucial to associate these genes to specific 22q-related conditions and this array will be instrumental towards this goal. Furthermore, comprehensive epigenetic profiling of 22q-located genes and high-resolution analysis of replication timing across the entire chromosome can be studied using our array., De två första författarna delar förstaförfattarskapet.

- Abstract
Sepsis is the systemic inflammatory host response to infection. Cystathionine beta-synthase (CBS)-dependent homocysteine (Hcy) pathway was demonstrated to affect disease severity and mortality in patients with severe sepsis/septic shock. Independent studies identified a single-nucleotide polymorphism (SNP, rs6586282, hg19 chr21:g.44478497C>T) in intron 14 of the CBS-coding gene (CBS) associated with Hcy plasma levels. We aimed to describe the association of this SNP and variants of a splice donor-affecting variable-number tandem repeat (VNTR, NG_008938.1:g.22763_22793[16_22]) 243 bp downstream of rs6586282 with severe human sepsis. We analyzed the VNTR structure and genotyped variants of rs6586282 and a neighboring SNP (rs34758144, hg19 chr21:g.44478582G>A) in two case–control studies including patients with severe sepsis/septic shock from Germany (n=168) and Greece (n=237). In both studies, we consistently observed an association of CBS VNTR alleles with sepsis susceptibility. Risk linearly increased with number of tandem repeats (per allele odds ratio in the adjusted analysis 1.34; 95% confidence interval (CI)=1.17–1.55; P<0.001). Association had also been shown for rs34758144 whose risk allele is in linkage disequilibrium with one long VNTR allele (19 repeat). In contrast, we observed no evidence for an effect on 28-day survival in patients with severe sepsis/septic shock (per allele hazard ratio in the adjusted analysis for VNTR 1.10; 95% CI=0.95–1.28; P=0.20). In a minigene approach, we demonstrated alternative splicing in distinct VNTR alleles, which, however, was independent of the number of tandem units. In conclusion, there is no ordinary conjunction between human CBS and severe sepsis/septic shock, but CBS genotypes are involved in disease susceptibility.

Glucose restriction mimicked by feeding the roundworm Caenorhabditis elegans with 2-deoxy-D-glucose (DOG) - a glucose molecule that lacks the ability to undergo glycolysis - has been found to increase the life span of the nematodes considerably. To facilitate understanding of the molecular mechanisms behind this life extension, we analyzed transcriptomes of DOG-treated and untreated roundworms obtained by RNA-seq at different ages. We found that, depending on age, DOG changes the magnitude of the expression values of about 2 to 24 percent of the genes significantly, although our results reveal that the gross changes introduced by DOG are small compared to the age-induced changes. We found that 27 genes are constantly either up- or down-regulated by DOG over the whole life span, among them several members of the cytochrome P450 family. The monotonic change with age of the temporal expression patterns of the genes was investigated, leading to the result that 21 genes reverse their monotonic behaviour under impaired glycolysis. Put simply, the DOG-treatment reduces the gross transcriptional activity but increases the interconnectedness of gene expression. However, a detailed analysis of network parameters discloses that the introduced changes differ remarkably between individual signalling pathways. We found a reorganization of the hubs of the mTOR pathway when standard diet is replaced by DOG feeding. By constructing correlation based difference networks, we identified those signalling pathways that are most vigorously changed by impaired glycolysis. Taken together, we have found a number of genes and pathways that are potentially involved in the DOG-driven extension of life span of C. elegans. Furthermore, our results demonstrate how the network structure of ageing-relevant signalling pathways is reorganised under impaired glycolysis. [ABSTRACT FROM AUTHOR]

- Abstract
Background The heritability of body composition has been studied extensively by researchers. However, few studies have explored the genetic variation of advanced body composition phenotypes derived from magnetic resonance imaging (MRI). In this study, polygenic risk scores (PRS) and single nucleotide polymorphisms (SNPs) that are associated with image-derived features from water- and fat separated MRI are reported. Method and materials The analysis was performed with the image processing framework Imiomics to attain spatial normalisation of large imaging cohorts from the UK Biobank. The study included 13,300 men and 13,849 women following GWAS and image data quality controls. Imiomics was further applied to generate voxel-wise Pearson correlation coefficient volumes. Relative effect sizes from six SNPs (rs1358980-T, rs1936805-T, rs2820443-C, rs6567160-C, rs10195252-C and rs13021737-G) were examined for associations with segmented tissue volumes and tissue fat fractions. In addition, the LDpred-derived PRS were compared with genome-wide significant only derived PRS for body mass index (BMI), waist-to-hip ratio (WHR) and height. Results Imiomics and GWAS integration delivered a detailed mapping of individual SNPs to the tissue volume and fat fraction of regional adipose tissue depots, heart, liver, lungs and thigh muscle. A putatively less harmful relationship between gluteofemoral SAT and the two obesity-related SNPs, rs6567160-C and rs1936805-T, compared with other tissues was found. The genetic variant, rs1358980-T, located upstream of VEGFA, was the highest ranked SNP inversely associated with gluteofemoral SAT volume in both sexes (r= -0.0245, p<0.05 and r= -0.0257, p<0.05 in men and women, respectively). Observed effect sizes were overall higher with LDpred-derived PRS compared with genome-wide significant only scores. Conclusion An image-based exploratory integration approach guided by Imiomics enabled efficient and large-scale analysis of advanced body c

BACKGROUND Little is known about current clinical practice concerning peri-operative red blood cell transfusion in neonates and small infants. Guidelines suggest transfusions based on haemoglobin thresholds ranging from 8.5 to 12���g���dl-1, distinguishing between children from birth to day 7 (week 1), from day 8 to day 14 (week 2) or from day 15 (���week 3) onwards. OBJECTIVE To observe peri-operative red blood cell transfusion practice according to guidelines in relation to patient outcome. DESIGN A multicentre observational study. SETTING The NEonate-Children sTudy of Anaesthesia pRactice IN Europe (NECTARINE) trial recruited patients up to 60 weeks' postmenstrual age undergoing anaesthesia for surgical or diagnostic procedures from 165 centres in 31 European countries between March 2016 and January 2017. PATIENTS The data included 5609 patients undergoing 6542 procedures. Inclusion criteria was a peri-operative red blood cell transfusion. MAIN OUTCOME MEASURES The primary endpoint was the haemoglobin level triggering a transfusion for neonates in week 1, week 2 and week 3. Secondary endpoints were transfusion volumes, 'delta haemoglobin' (preprocedure - transfusion-triggering) and 30-day and 90-day morbidity and mortality. RESULTS Peri-operative red blood cell transfusions were recorded during 447 procedures (6.9%). The median haemoglobin levels triggering a transfusion were 9.6 [IQR 8.7 to 10.9] g���dl-1 for neonates in week 1, 9.6 [7.7 to 10.4] g���dl-1 in week 2 and 8.0 [7.3 to 9.0] g���dl-1 in week 3. The median transfusion volume was 17.1 [11.1 to 26.4] ml���kg-1 with a median delta haemoglobin of 1.8 [0.0 to 3.6] g���dl-1. Thirty-day morbidity was 47.8% with an overall mortality of 11.3%. CONCLUSIONS Results indicate lower transfusion-triggering haemoglobin thresholds in clinical practice than suggested by current guidelines. The high morbidity and mortality of this NECTARINE sub-cohort calls for investigative action and evidence-based guidelines addressing peri-operative red blood cell transfusions strategies.

RBS de dois estágios ,Aeração intermitente ,Energia solar ,Lodo ativado ,Clima quente - Abstract
Um sistema de lodo ativado do tipo reator de bateladas sequenciais (RBS) de dois estágios com aeração intermitente e alimentado por energia solar foi estudado, para avaliar seu desempenho na remoção de material orgânico (MO), nitrogênio e fósforo de esgotos domésticos em clima tropical. Na pesquisa, foi avaliada também a influência do tempo de aeração noturna na vida útil das baterias e na eficiência do sistema. O sistema foi submetido às vazões diárias afluentes de 3, 4,5 e 6 m³/dia, e posteriormente a uma redução do tempo de aeração diária de 360 para 300 minutos. Os resultados indicaram uma alta eficiência e estabilidade da ETE no tratamento de esgotos domésticos durante todo o experimento, atingindo eficiências médias de 93 ± 2%, 86 ± 4% e 93 ± 6%, na remoção de MO, nitrogênio e fósforo, respectivamente. A biomassa do sistema é robusta em relação à operação com longos períodos com baixa concentração de OD (sem aeração em 80% do tempo da batelada). No entanto, ficou evidenciada a existência de um limite na concentração de sólidos do sistema (4,3 gSST/L), acima do qual a sedimentação é prejudicada. A solar self-sufficient two-stage RBS-AS system submitted to long non-aerated periods (intermittent aeration) was studied to evaluate its performance in removing MO, nitrogen and phosphorus from domestic wastewater. The influence of aeration time on battery life was also evaluated. The system was subjected to daily inflows of 3, 4.5 and 6m³/day, and sludge ages of 32 ± 2 and 21 ± 2 days. The results indicated a high efficiency and stability of the system in the domestic wastewater treatment, reaching efficiencies of 93 ± 2%, 86 ± 4% and 93 ± 6%, in the removal of BOD, N and P, respectively. The biomass of the system is robust in relation to long-term operation with low DO concentration (without aeration for 80% of the batch time). However, the presence of a solids concentration limit (4.3 gSST / l), above which sedimentation is impaired, was evidenced. The durations of the aeration fases can be adjusted as a strategy to extend the life of the photovoltaic system's batteries.

Nikolai Otto, Prof. Dr. Alvaro Luiz Mathias Dissertação (mestrado) - Universidade Federal do Paraná, Setor de Tecnologia, Programa de Pós-Graduação em Meio Ambiente Urbano e Industrial. Defesa : Curitiba, 10/09/2019 Inclui referências: p. 93-100 Resumo: O formaldeído é um importante composto químico, muito utilizado em produtos do nosso dia-a-dia, desde cosméticos aos combustíveis que utilizamos em veículos. A utilização do formaldeído e a exposição ao mesmo podem acarretar sérios problemas de saúde e doenças, como o câncer. Neste contexto, o estudo e aplicação de métodos de degradação do formaldeído em água são essenciais. O objetivo do presente trabalho foi avaliar o potencial de aplicar a fotoxidação de formaldeído em soluções artificiais contendo formaldeído em concentração conhecida. O método analítico escolhido para quantificação de formaldeído foi o espectrofotométrico com a utilização de ácido cromotrópico em meio ácido. Esse método apresentou melhor resultado que o método analítico 3-metil 2 benzotiazolinona hidro cloreto de hidrazona (MBTH) e o método 4-Amino 3-penten 2-ona (Fluoral P). Para a fotodegradação do formaldeído nas amostras foi realizada a associação da irradiação ultravioleta com lâmpadas de LED, com a utilização de placas de silicato e boro silicato e adição de peróxido de hidrogênio com pH ácido.Quando utilizado somente as placas de silicato e boro-silicato foram obtidos uma degradação preliminar de 14% de formaldeído, quando foi combinado com a adição de peróxido de hidrogênio foram atingidos apenas 7% de degradação. Pórem, quando houve a acidificação do meio, a remoção atingiu valores aproximados de 30 % com dosagem de peróxido de hidrogênio abaixa da relação estequiométrica. Palavras-chave: Formaldeído. Degradação. Água. Fotoxidação. Abstract: Formaldehyde is an important chemical compound, widely used in products of our daily lives, from cosmetics to fuels we use in vehicles. The use of formaldehyde and exposure to it can cause serious health problems and diseases, such as cancer. In this context, the study and application of formaldehyde degradation methods in water are essential. The objective of this work was to evaluate the potential of applying photoxidation of formaldehyde in artificial solutions containing formaldehyde in a known concentration. The analytical method chosen to quantify formaldehyde was spectrophotometric with the use of chromotropic acid in acid medium. This method presented better results than the 3-methyl 2- benzothiazolinone hydrochloride hydrazone (MBTH) analytical method and the 4- Amino 3-penten 2-one method (Fluoral P). For photodegradation of formaldehyde in the samples, ultraviolet irradiation was associated with LED lamps, with the use of silicate and boron silicate plates and addition of hydrogen peroxide with acid pH; when only silicate and boron silicate plates were used, a preliminary degradation of 14% of formaldehyde was obtained, when combined with the addition of hydrogen peroxide, only 7% of degradation was achieved. However, when there was acidification of the medium, the removal reached values of approximately 30% with dosage of hydrogen peroxide lowering the stoichiometric ratio. Keywords: Formaldehyde.

Disease epidemiology during ageing shows a transition from cancer to degenerative chronic disorders as dominant contributors to mortality in the old. Nevertheless, it has remained unclear to what extent molecular signatures of ageing reflect this phenomenon. Here we report on the identification of a conserved transcriptomic signature of ageing based on gene expression data from four vertebrate species across four tissues. We find that ageing-associated transcriptomic changes follow trajectories similar to the transcriptional alterations observed in degenerative ageing diseases but are in opposite direction to the transcriptomic alterations observed in cancer. We confirm the existence of a similar antagonism on the genomic level, where a majority of shared risk alleles which increase the risk of cancer decrease the risk of chronic degenerative disorders and vice versa. These results reveal a fundamental trade-off between cancer and degenerative ageing diseases that sheds light on the pronounced shift in their epidemiology during ageing., Nature Communications, 9, ISSN:2041-1723

O Brasil e a Alemanha apresentam realidades contrastantes na legislação, geração, separação e destinação dos resíduos sólidos domiciliares. A Alemanha possui regras rígidas em relação a resíduos sólidos e é considerada modelo europeu em tecnologia, eficiência de tratamento e reciclagem. Neste sentido, o presente estudo busca definir propostas de melhoramento da gestão de resíduos sólidos domiciliares do município de Araucária, Brasil, com base no estudo de caso da cidade de Stuttgart, Alemanha. Para tanto a dissertação utiliza uma análise comparativa, a nível federal e a nível municipal, das principais etapas de gerenciamento dos resíduos sólidos. Os resultados foram obtidos por meio da análise dos dados institucionais e visitas técnicas nos órgãos de gestão pública, assim como em instalações de reciclagem, compostagem, aterro e incineração. A discussão reflete sobre as diferenças existentes entre o gerenciamento de resíduos nas duas cidades e aponta sugestões de melhoramento para a cidade brasileira, como por exemplo, a necessidade de revisão de leis municipais, fomento á compostagem, inserção de dados sobre a gestão dos resíduos no site institucional, criação de plataforma online de doação de produtos e criação de Comissão Técnica Municipal de Resíduos Sólidos. Palavras-chave: gestão municipal. gerenciamento de resíduos. comparação de gestão. Abstract: Each country conducts business management with its policies, economy, environment, culture and social.

Daniela Neufer Dissertação (mestrado) - Universidade Federal do Paraná, Setor de Tecnologia, Programa de Pós-Graduação em Meio Ambiente Urbano e Industrial,em parceria com o curso de Mestrado Waste, da Universidade de Stuttgart . Defesa : Stuttgart, 12/02/2018 Inclui referências: p.79-87 Resumo: No capítulo 1, é apresentada a introdução das estações de tratamento de efluente compactas, que vem sendo usadas na Alemanha nos últimos 15 anos, pelo menos, e também em países como China e Dinamarca. Como água e esgoto ainda são um problema preocupante em países em desenvolvimento, como o Brasil, o objetivo desse projeto apresentada no item 2 é avaliar a eficiência de uma estação de tratamento de efluentes compacta com baixa geração de lodo e operando com energia solar, para no futuro aplicar o projeto no Nordeste brasileiro. Projetos como esse apresentam grande importância para o desenvolvimento de países como o Brasil onde falta investimento em saneamento e em pesquisas. No capítulo 3, são apresentados parâmetros de tratamento de esgoto por lodos ativados, bem como a eficiência de remoção de carbono e nitrogênio esperada para uma estação compacta como a utilizada na pesquisa, que são respectivamente >90% e entre 10-70%. As legislações alemãs e brasileiras são também apresentadas, sendo que na Alemanha existe a norma DIN EN 12566-3, específica para estações compactas, diferentemente do Brasil, onde não existe legislação específica, porém cada existe a obrigatoriedade de tratar o esgoto produzido em uma residência quando rede de tratamento de esgoto não é disponível de acordo com o DECRETO N° 7.212/10. No item 4, a estação de tratamento de efluente compacta é apresentada, chamada BioTopp, foi inicializada para o equivalente populacional de 6 pessoas e parâmetros como temperatura, pH, oxigênio, volume de lodo, demanda bioquímica de oxigênio (DQO) e nitrogênio foram analisados em três diferentes fases, sendo fase de avaliação com os controles operacionais fornecidos pelo fabricante e teste 1 e 2, onde foram alterados tempo de aeração e pause no processo, respectivamente. Os resultados, no capítulo 5, mostraram que a planta atinge as condições pré-estabelecidas para remoção de nutrientes, através da nitrificação e desnitrificação, além de redução de carga orgânica. A planta apresentou eficiência na remoção de DQO entre 74 e 93% e 59 a 94% de eficiência na remoção de amônio. Foram observadas variações nas condições de entrada do efluente, o que pode ter comprometido o tratamento, levando em consideração que a estação é sensível a variações tanto no afluente quanto nos parâmetros de controle operacionais. Durante o teste 1, a planta apresentou os melhores resultados em remoção de matéria orgânica e, no teste 2, a planta apresentou melhores resultados na remoção de nitrogênio. De acordo com o órgão ambiental responsável na Alemanha, a estação pode ser classificada como classe C. Conclui-se por fim, no capítulo 6, que a planta é uma boa alternativa para casas sem acesso a saneamento. Além disso, a planta é operada foi operada automaticamente durante os meses analisados, sem requerimentos de manutenção e a operação com painéis solares mostrou-se possível e eficiente durante o verão europeu onde os valores apresentados de irradiação solar horizontal global são menores que no Brasil. PALAVRAS CHAVE: Estação de tratamento de efluente compacta, efluente doméstico, energia solar. Abstract: Water and wastewater management is still a worrisome problem in underdeveloped and developing countries, like Brazil. Small scale wastewater treatment plants (WTTP's) have been used in Germany for at least in the last 15 years and also in other countries, such as China and Denmark. For this reason, the aim of the current study is to evaluate the efficiency of a compact WWTP with low waste production operated by solar energy in order to consider the application of this project in the future in the Northeast region in Brazil. Projects such as this one contribute to their development by providing new technologies to supply the lack of investment in sanitation and in research. A small-scale WWTP, BioTopp, was started up for 6 populations equivalent (PE) and parameters like temperature, pH-value, oxygen and settled sludge volume were analysed during one month. The results of the first evaluation showed that the plant achieves the conditions for nitrification and denitrification process. After that, another parameters started being analysed, such as COD, ammonium, nitrite, nitrate, solids content and sludge volume index. Biotopp showed efficiency in COD removal between 74 to 93%, ammonium 59 to 94%. However, it was observed that the small-scale plant is very sensitive to variations in the inflow characteristics and in the controlling parameters. According to DIBt, the plant can be classified as class C and it showed to be a good alternative for households located in places without wastewater collection and treatment. The plant operates automatically and during the European summer the solar panels and batteries supplied all of the power demand. KEY WORDS: Small-scale wastewater treatment plant, domestic wastewater, solar energy.

Karen Juliana Amaral Dissertação (mestrado) - Universidade Federal do Paraná, Setor de Tecnologia, Programa de Pós-Graduação em Meio Ambiente Urbano e Industrial. Defesa : Curitiba, 15/12/2017 Inclui referências Resumo: Água é um insumo essencial à vida. Entretanto, por falta de saneamento básico, este recurso está ameaçado graças à contaminação que o ser humano vem provocando. Uma das formas de poluição ocorre com o lançamento de despejos irregulares de esgoto, que são dispensados irregularmente no solo, percolando até aquífero. A amônia presente nesses despejos, por meio do ciclo do nitrogênio, se converte em nitrito e depois em nitrato, chegando até o aquífero, contaminando a água. Este é o caso das águas subterrâneas da cidade de Natal, localizada no estado do Rio Grande do Norte, onde foram verificados níveis de nitrato acima do permitido pela Portaria do Ministério da Saúde, nº 2914, de 12 de dezembro de 2011 (10 mg/L NO3). A remoção deste componente pode ser realizada com a tecnologia de troca iônica, que se baseia no intercâmbio iônico utilizando princípio de afinidade química com a utilização de esferas de copolímeros de estireno e divenilbenzeno. Em um período de junho de 2016 a março de 2017, para a potabilização de um poço contaminado no bairro da Candelária, em Natal, um filtro automático utilizando essa tecnologia foi instalado, operando com uma vazão de 12 m3 /h, em leito fixo, utilizando filtro de areia como pré-tratamento. Nos meses de junho a novembro obteve-se eficiência média de 86 % e durante campanha extra realizada em novembro, obteve-se eficiência média de 91 %. Já durante a campanha extra realizada em março, observou-se a preferência do íon sulfato pela resina, bem como um aumento no teor de cloreto na água bruta, que influenciaram diretamente na remoção do íon nitrato, alterando a performance da planta piloto. Realizando um Payback da planta piloto, verificou-se um valor médio de 6,4 meses. Fazendo um estudo do custo da água desnitrificada pela planta piloto, observou-se um valor de R$ 0,70 por m3, valor 13 vezes mais barato do que o cobrado pela companhia de saneamento local. Palavras-chave: Resinas de Troca Iônica. Nitrato. Remoção de Nitrato. Natal-RN. Abstract: Water is an essential input to life. However, due to lack of basic sanitation, this resource is threatened thanks to the contamination that the humans been doing. One of the forms of pollution occurs with the launch of irregular sewage dumps, which are dispensed irregularly in the soil, percolating up to groundwater. The ammonia present in these dumps, through the nitrogen cycle, becomes nitrite and then into nitrate, reaching the groundwater, contaminating the water. This is the case observed in the groundwater of the city of Natal, located in the state of Rio Grande do Norte, where nitrate levels were higher than allowed by Ministry of Health Ordinance No. 2914 of December 12, 2011 (10 mg/L NO3). Removal of this component can be accomplished with ion exchange technology, which is based on the ion exchange of ions using chemical affinity principle with the use of styrene and divenylbenzene copolymer beads. From June 2016 to March 2017, an automatic filter using this technology was installed at a flow rate of 12 m3 /h in a fixed bed, using a fixed bed, for the purification of a contaminated well in the Candelária district of Natal. sand filter as pre-treatment. In the months of June to November, an average efficiency of 86 % was obtained and during an extra campaign in November, an average efficiency of 91 % was obtained. Already during the extra campaign in March, the preference of the sulfate ion was observed for the resin, as well as an increase in the chloride content in the raw water, which directly influenced the nitrate ion removal, altering the performance of the pilot plant. Performing a Payback of the pilot plant, an average value of 6.4 months was verified. A study of the cost of denitrified water by the pilot plant showed a value of R $ 0.70 per m3, which is 13 times cheaper than that charged by the local sanitation company. Key-words: Ion Exchange.

Dentre as práticas para racionalização do uso e conservação dos recursos hídricos se encontra o reúso e a recuperação de águas residuárias, que vêm ganhando maior visibilidade com o incremento dos custos de abastecimento de água bruta, do tratamento e da disposição final dos efluentes tratados. O objetivo deste trabalho foi avaliar alternativas para o reúso de água industrial não potável, a partir de efluentes industriais gerados em uma linha de pré-tratamento de superfícies de uma fábrica de produção de cabines de caminhões. A redução dos impactos ambientais, por meio da conservação de água bruta, ou seja, disponibilizando volumes de água para usos mais nobres e cooperando com a redução dos efluentes gerados a serem tratados, apresentou-se como uma das principais justificativas deste estudo. As ferramentas utilizadas foram o levantamento de dados quantitativos sobre demanda de água e geração de efluentes obtidos em campo, a caracterização da água industrial e desmineralizada por meio de análises de pH, condutividade, TDS, DQO e turbidez, a caracterização dos efluentes gerados em cada estágio dos banhos responsáveis pelo processo de pré-tratamento de superfícies por meio de análises de pH, condutividade, TDS e DQO e a caracterização na entrada e saída da estação de tratamento de efluentes industriais (ETEI) onde foram realizadas análises de pH, condutividade, TDS, DQO e turbidez. Com estas informações foi possível avaliar diferentes opções de reúso do efluente sem tratamento e de reúso após o tratamento na ETEI. Os resultados obtidos indicaram que os banhos de enxágues representaram aproximadamente 80% de toda fonte de geração de efluentes em um processo de pré-tratamento de superfícies preliminar à pintura, assim como efluentes que apresentaram características físico-químicas com boas possibilidades para o reúso em cascata. Uma comparação entre o perfil físico químico do efluente na saída da ETEI e a qualidade de água industrial utilizada no processo indicou que é necessário o uso de tecnologias avançadas para permitir o reúso do efluente na saída da ETEI.

Among the practices for rational use and conservation of water resources is the reuse and recovery of wastewater, which are gaining greater visibility due to the increase of costs of raw water supply, treatment and final disposal of the treated effluent. This study aims at the evaluation of alternatives to the reuse of non-potable industrial water derived from wastewater generated in a line of pre-treatment of surfaces of a truck cabins production plant. The reduction of environmental impacts through the raw water conservation, that is, the provision of water volumes for more noble uses and cooperating with the reduction of effluents to be treated, is presented as one of the main reasons of this work. The tools used to achieve the purposes of this study were quantitative data survey on demand for water and wastewater generation from the field, characterization of industrial and demineralized water by means of pH, conductivity, TDS, COD and turbidity analysis, the characterization of the effluents at each stage of the baths responsible for the pre-surface treatment process by means of pH, conductivity, TDS and COD analysis and characterization in input and output of industrial wastewater treatment station (ETEI) where pH, conductivity, TDS, COD and turbidity analyzes were performed. Based on this information it was possible to evaluate different options for reuse of wastewater without treatment and reuse after treatment in ETEI. The results indicated that the rinses baths represented approximately 80% of all source of effluent generation in a process of pretreating of surfaces prior to painting, as well as effluents that showed physico-chemical properties with good possibilities for cascading reuse. A comparison of the physical-chemical profile of the effluent in ETEI output and quality of industrial water used in the process indicated that it is necessary to use advanced technology to enable the reuse of the effluent in ETEI output. Keywords: Reuse of Cascading Effluent. Paint Pretreatment. Water balance.
