Enhancing robustness of activated sludge with Aspergillus tubingensis as a protective backbone structure under high-salinity stress.

J Environ Manage 2021 Jul 19;297:113302. Epub 2021 Jul 19.

State Key Laboratory of Chemical Resource Engineering, Beijing Key Laboratory of Bioprocess, Beijing, 100029, People's Republic of China; Beijing Advanced Innovation Center for Soft Matter Science and Engineering, Beijing, 100029, People's Republic of China; Beijing University of Chemical Technology, Beijing, 100029, People's Republic of China. Electronic address:

High salt seriously destroys the stable interactions among key functional species of activated sludge, which in turn limits the performance of high-salinity wastewater biological treatment. In this study, pelletized Aspergillus tubingensis (AT) was used as a protective backbone structure for activated sludge under high-salinity stress, and a superior salt-tolerant AT-based aerobic granular sludge (AT-AGS) was developed. Results showed that the COD and NH-N removal efficiencies of salt-domesticated AT-AGS were 11. Read More

National Key Laboratory for Swine Genetic Improvement and Production Technology, Ministry of Science and Technology of China, Jiangxi Agricultural University, Nanchang, Jiangxi Province, 330045, China.

Intramuscular fat (IMF) content is a critical indicator of pork quality that affects directly the purchasing desire of consumers. However, to measure IMF content is both laborious and costly, preventing our understanding of its genetic determinants and improvement. In the present study, we constructed an accurate and fast image acquisition and analysis system, to extract and calculate the digital IMF content, the proportion of fat areas in the image (PFAI) of the longissimus muscle of 1709 animals from multiple pig populations.

Fingerprinting diverse nanoporous materials for optimal hydrogen storage conditions using meta-learning.

Sci Adv 2021 Jul 21;7(30). Epub 2021 Jul 21.

Department of Chemistry and Chemical Theory Center, University of Minnesota, 207 Pleasant Street SE, Minneapolis, MN 55455-0431, USA.

Adsorptive hydrogen storage is a desirable technology for fuel cell vehicles, and efficiently identifying the optimal storage temperature requires modeling hydrogen loading as a continuous function of pressure and temperature. Using data obtained from high-throughput Monte Carlo simulations for zeolites, metal-organic frameworks, and hyper-cross-linked polymers, we develop a meta-learning model that jointly predicts the adsorption loading for multiple materials over wide ranges of pressure and temperature. Meta-learning gives higher accuracy and improved generalization compared to fitting a model separately to each material and allows us to identify the optimal hydrogen storage temperature with the highest working capacity for a given pressure difference.

Hi-C 3.0: Improved Protocol for Genome-Wide Chromosome Conformation Capture.

Curr Protoc 2021 Jul;1(7):e198

Program in Systems Biology, Department of Biochemistry and Molecular Pharmacology, University of Massachusetts Medical School, Worcester, Massachusetts.

The intricate folding of chromatin enables living organisms to store genomic material in an extremely small volume while facilitating proper cell function. Hi-C is a chromosome conformation capture (3C)-based technology to detect pair-wise chromatin interactions genome-wide, and has become a benchmark tool to study genome organization. In Hi-C, chromatin conformation is first captured by chemical cross-linking of cells. Read More

Latest impact of engineered human liver platforms on drug development.

APL Bioeng 2021 Sep 16;5(3):031506. Epub 2021 Jul 16.

Department of Bioengineering, University of Illinois at Chicago, Chicago, Illinois 60607, USA.

Drug-induced liver injury (DILI) is a leading cause of drug attrition, which is partly due to differences between preclinical animals and humans in metabolic pathways. Therefore, human liver models are utilized in biopharmaceutical practice to mitigate DILI risk and assess related mechanisms of drug transport and metabolism. However, liver cells lose phenotypic functions within 1-3 days in two-dimensional monocultures on collagen-coated polystyrene/glass, which precludes their use to model the chronic effects of drugs and disease stimuli.

Age-Related Neurometabolomic Signature of Mouse Brain.

ACS Chem Neurosci 2021 Jul 20. Epub 2021 Jul 20.

Institute for Genomics and Bioinformatics, School of Information and Computer Sciences, University of California-Irvine, Irvine, California 92697, United States.

Neurometabolites are the ultimate gene products in the brain and the most precise biomolecular indicators of brain endophenotypes. Metabolomics is the only "omics" that provides a moment-to-moment "snapshot" of brain circuits' biochemical activities in response to external stimuli within the context of specific genetic variations. Although the expression levels of neurometabolites are highly dynamic, the underlying metabolic processes are tightly regulated during brain development, maturation, and aging. Read More

A Flexible System for Stepwise Automation of Microbial Testing of Drinking and Process Water.

SLAS Technol 2021 Jul 20:24726303211017534. Epub 2021 Jul 20.

Institute of Natural Materials Technology, Chair of Bioprocess Engineering, Technische Universität Dresden, Dresden, Germany.

Ambitions to improve the connectivity of devices to enable automation and digital representation of processes have been around for some time. Nevertheless, some companies, especially in life science and analytical science, tend to adopt these developments rather slowly. In the field of microbial analysis of drinking and process water, for example, a large part of the work is still carried out manually, although the high number of samples per day and the low fluctuation in work processes would predestine water analysis for a higher degree of automation.

Assessing the replicability of spatial gene expression using atlas data from the adult mouse brain.

PLoS Biol 2021 Jul 19;19(7):e3001341. Epub 2021 Jul 19.

Cold Spring Harbor Laboratory, Cold Spring Harbor, New York, United States of America.

High-throughput, spatially resolved gene expression techniques are poised to be transformative across biology by overcoming a central limitation in single-cell biology: the lack of information on relationships that organize the cells into the functional groupings characteristic of tissues in complex multicellular organisms. Spatial expression is particularly interesting in the mammalian brain, which has a highly defined structure, strong spatial constraint in its organization, and detailed multimodal phenotypes for cells and ensembles of cells that can be linked to mesoscale properties such as projection patterns, and from there, to circuits generating behavior. However, as with any type of expression data, cross-dataset benchmarking of spatial data is a crucial first step. Read More

Heliyon 2021 Jul 29;7(7):e07430. Epub 2021 Jun 29.

Department of Electrical and Computer Engineering, Universitas Syiah Kuala, Banda Aceh, 23111, Indonesia.

Device-to-device (D2D) communication is one of the key enabling technologies for 5G to support many connections efficiently. In a cooperative out-band D2D communication network, relay nodes have an essential role in receiving and forwarding information signals from source (S) to destination (D), making the system more reliable and with higher energy efficiency. Therefore, the relay selection method is very important in determining the best relay among existing relays to achieve maximum performance. Read More

Front Plant Sci 2021 2;12:685156. Epub 2021 Jul 2.

School of Applied Biosciences, Kyungpook National University, Daegu, South Korea.

Nitric oxide (NO) is a signaling molecule that regulates various processes, including plant growth and development, immunity, and environmental interactions. Using high throughput RNA-seq data, we explored the role of the NO-induced gene in plant growth and defense using functional genomics. The mutant and wild-types were challenged with either oxidative (HO, MV) or nitro-oxidative (CySNO, GSNO) stress conditions, and the phenotypic results showed that gene differentially regulates cotyledon development frequency (CDF) as well as the root and shoot lengths of the plants.

Faculty of Food and Biochemical Technology, Department of Biochemistry and Microbiology, University of Chemistry and Technology, Prague, Czechia.

A bacterial species is best characterized after its isolation in a pure culture. This is an arduous endeavor for many soil microorganisms, but it can be simplified by several techniques for improving culturability: for example, by using growth-promoting factors.
