Fibres fractionated from solid recovered fuel (SRF), a standardised market combustion fuel produced from sorted waste, were considered as a source of lignocellulosic fermentable sugars. The fibre yield from four samples of SRF was 25-45%, and the separated material consisted of 52-54% carbohydrates, mainly glucan, with a high content of ash (12-17%). The enzymatic digestibility of recovered fibres was studied at low and high solids loading and compared with model substrates containing only chemical and mechanical pulps. Above 80% hydrolysis yield was reached at 20% solids loading in 48 h, but variation was observed between different samples of recovered fibres. Surfactants were found to improve the hydrolysis yield of recovered fibres especially in tumbling-type of mixing at low solids loading, where hydrolysis was found to stagnate without surfactants. The results suggest that SRF is a potential source of easily digestible lignocellulosic carbohydrates for use in biorefineries.

Iodine, being an important resource, must be recovered and reused. Iodine is not only attracted to the hydrophobic silicone membrane but also easily vaporized. In this study, we explored the use of five types of silicone hollow fiber membrane modules (SFMMs) for separating iodine in the gaseous phase.

COVID-19 infection has been linked to ocular involvement, particularly retinal microvascular changes. Additionally, prolonged hypoxemia may affect retinal sublayers located within the retinal watershed zone. The aim of this study was to evaluate retinal and optic nerve OCT parameters in patients with COVID-19 illness of varying severity and compare them with controls.

Dynamic high-pressure microfluidization (DHPM) is an emerging treatment technology and has been widely used for the recovery of natural polysaccharides. The aim of the present contribution is to discuss the DHPM-assisted extraction and processing of polysaccharides from some foods and by-products by reviewing the instrument and working principle, procedures, key parameters, and effects of DHPM on the structures, food properties, and bioactivities of resulting polysaccharides. It was found that a DHPM instrument with Z-type chamber is preferable for extracting polysaccharides, and a DHPM with Y-type chamber is applicable for processing polysaccharides.

Major depressive disorder (MDD) is among the most common mental disorders worldwide and is characterized by dysregulated reward processing associated with anhedonia. Selective serotonin reuptake inhibitors (SSRIs) are the first-line treatment for MDD; however, their onset of action is delayed. Recent reports have shown that serotonin neurons in the dorsal raphe nucleus (DRN) are activated by rewards and play a vital role in reward processing.
