Deconvolution of autoencoders to learn biological regulatory modules from single cell mRNA sequencing data.

methods of unsupervised machine learning (learning to) has demonstrated its usefulness in a single cell mRNA noisy data-sequencing (scRNA-seq), where models generalize well, although a zero-inflation of the data. A class of neural networks, namely autoencoders, has been useful for denoising a single cell data, imputed values ​​and dimensions reduction.Here missing, we present a striking … Read more

At the end of the period at 20.0 mg HS - S / L, specific levels of consumption and the formation of ammonium nitrate is 15 and 55% lower than the values ​​in each control period without the addition of sulphide, which indicates that the mud had better adaptation metabolic activities of the oxidizer ammonium nitrite oxidation activity. sludge obtained sulfide oxidation capacity higher throughout the cycle. Bacterial population dynamics assessment showed that ammonium oxidizing bacteria (AOB) community more diverse and stable than nitrite-oxidizing bacteria (NOB) community. Use of a consortium with previous nitrification activity stabilized in the SBR may be an alternative to eliminate simultaneous nitrification and ammonium sulfide by oxidation of sulphides and applied for wastewater treatment with ammonium and sulfide.

Metagenomics Shotgun sequencing is a powerful tool for the characterization of complex biological matrices, analysis of prokaryotic and eukaryotic organisms allowed in a single experiment, with the possibility of de novo reconstruction of the entire metagenome or a set of genes of interest. One of the main factors that limit the use of metagenomics rifle … Read more

Hypersaline wastewater may pose a threat to the biological wastewater treatment process. Reactor-based aerobic granular sludge sequencing batch (SBR) perform simultaneous nitrification, denitrification and removal of phosphorus (SNDPR) was evaluated with an increase in salinity of 1 to 2% (w / v). nitrogen deletion performance is not affected by the salinity of up to 20 g / L in terms of nitrification and denitrification are reliable and efficient. Enhanced biological elimination of phosphorus (EBPR) process actually worsened in the salinity of up to 2%, in contrast with the removal of phosphorus excellent at 1%. Profile phosphorus over one cycle shows that the higher salinity not only inhibits anaerobic phosphorus release, but also hampered the aerobic / anoxic phosphorus uptake.

Sequencing artifacts, clonal hematopoietic potential mutation indeterminate (CHIP) and the heterogeneity of the tumor has been hypothesized to contribute to the low suitability of tissue and cell-free DNA (cfDNA) with a targeted molecular profiling sequencing.We cfDNA analyzed by targeted sequencing of Hypersaline wastewater may pose a threat to the biological wastewater treatment process. samples from … Read more
