Wastewater treatment by microalgae.

Physiol Plant 2021 Apr 16. Epub 2021 Apr 16.

Department of Chemistry, Umeå University, Umeå, Sweden.

The growth of the world's population expands the demand for fresh water, food, energy and technology, which on their turn lead to increasing amount of wastewater, produced both by domestic and industrial sources. These different wastewaters contain a huge variety of organic and inorganic compounds, which can cause tremendous environmental problems if released untreated. Traditional treatment systems are usually expensive and energy demanding and often still not capable of facing all challenges presented by the produced wastewaters. Read More

Interaction of agonists of a different subtype of the nAChR and carvacrol with GABA in somatic muscle contractions.

J Nematol 2021 26;53. Epub 2021 Mar 26.

Faculty of Veterinary Medicine, University of Belgrade, Bul. oslobodjenja 18, 11000, Belgrade, Serbia.

Resistance of parasitic nematodes to anthelmintic drugs is a growing problem in human and veterinary medicine. The molecular mechanisms by which nematodes become resistant are different, but certainly one of the possible processes involves changing the drug binding site on the specific receptor. The significance of changes in individual subtypes of nicotinic acetylcholine receptors (nAChRs) for the development of resistance has not been clarified in detail. Read More

Real-time Base Excision Repair Assay to Measure the Activity of the 8-oxoguanine DNA Glycosylase 1 in Isolated Mitochondria of Human Skin Fibroblasts.

Bio Protoc 2021 Mar 20;11(6):e3954. Epub 2021 Mar 20.

Department of Life Sciences, Albstadt-Sigmaringen University of Applied Sciences, Sigmaringen, Germany.

7,8-dihydro-8-oxoguanine (8-oxoG) is one of the most common and mutagenic oxidative DNA damages induced by reactive oxygen species (ROS). Since ROS is mainly produced in the inner membranes of the mitochondria, these organelles and especially the mitochondrial DNA (mtDNA) contained therein are particularly affected by this damage. Insufficient elimination of 8-oxoG can lead to mutations and thus to severe mitochondrial dysfunctions. Read More

Mindfulness and acceptance-based behavioral treatment for bulimia-spectrum disorders: A pilot feasibility randomized trial.

Int J Eat Disord 2021 Apr 14. Epub 2021 Apr 14.

Center for Weight, Eating, and Lifestyle Science, Drexel University, Philadelphia, Pennsylvania, USA.

Objective: Although existing research supports the efficacy of mindfulness- and acceptance-based treatments (MABTs) for eating disorders (EDs), few studies have directly compared outcomes from MABTs to standard CBT.

Method: Participants (N = 44), treatment-seeking adults with bulimia-spectrum EDs, were screened for eligibility, consented, and randomized to receive 20 sessions of outpatient, individual CBT or MABT treatment. Treatment outcomes (binge eating and compensatory behavior episodes, global ED severity, depressive symptoms, quality of life, emotional awareness/clarity, distress tolerance, values-based decision-making, and emotion modulation) were measured at pre-treatment, post-treatment, and 6-month follow up.

Nature-Inspired Hierarchical Protrusion Structure Construction for Washable and Wear-Resistant Superhydrophobic Textiles with Self-Cleaning Ability.

ACS Appl Mater Interfaces 2021 Apr 12. Epub 2021 Apr 12.

Fraunhofer USA, Inc., Center Midwest, Division for Coatings and Diamond Technologies, Michigan State University, East Lansing, Michigan 48824, United States.

The use of toxic components and short longevity greatly restricted the commercial application of superhydrophobic surfaces in oil-water separation, antifouling, and self-cleaning. To address these concerns, a durable, robust, and fluorine-free superhydrophobic fabric is prepared on account of inspiration of nature. In this work, submicrometer-sized silica particles with different particle sizes are deposited onto cotton fabrics, followed by hydrophobic modification of poly(dimethylsiloxane) (PDMS), and consequently bonded the substrate and coating via powerful covalent bonds through a simple dip-coating technique.

Biodegradable Materials for Sustainable Health Monitoring Devices.

ACS Appl Bio Mater 2021 Jan 23;4(1):163-194. Epub 2020 Dec 23.

Bendable Electronics and Sensing Technologies (BEST) Group, James Watt School of Engineering, University of Glasgow, G12 8QQ Glasgow, U.K.

The recent advent of biodegradable materials has offered huge opportunity to transform healthcare technologies by enabling sensors that degrade naturally after use. The implantable electronic systems made from such materials eliminate the need for extraction or reoperation, minimize chronic inflammatory responses, and hence offer attractive propositions for future biomedical technology. The eco-friendly sensor systems developed from degradable materials could also help mitigate some of the major environmental issues by reducing the volume of electronic or medical waste produced and, in turn, the carbon footprint.

Well-to-wake analysis of switchgrass to jet fuel via a novel co-fermentation of sugars and CO.

Sci Total Environ 2021 Mar 27;782:146770. Epub 2021 Mar 27.

Biosystems and Agricultural Engineering, Oklahoma State University, Stillwater, OK, USA.

Lignocellulosic biomass such as switchgrass can be converted to n-butanol using fermentation, which can be further processed into jet fuel. Traditional acetone-butanol-ethanol (ABE) fermentation only converts sugars derived from switchgrass to ABE. Novel co-fermentation processes convert sugars and gas (CO/H) produced during fermentation into butanol, thus increasing ABE yields by 15. Read More

Motif Discovery from CLIP Experiments.

Methods Mol Biol 2021 ;2284:43-50

Centre for Molecular Bioinformatics, Department of Biology, University of Rome Tor Vergata, Rome, Italy.

RNA primary and secondary motif discovery is an important step in the annotation and characterization of unknown interaction dynamics between RNAs and RNA-Binding Proteins, and several methods have been developed to meet the need of fast and efficient discovery of interaction motifs. Recent advances have increased the amount of data produced by experimental assays and there is no available method suitable for the analysis of all type of results. Here we present a simple workflow to help choosing the more appropriate method, depending on the starting situation, among the three algorithms that best cover the landscape of approaches. Read More
