Reprocessable and Recyclable Materials for 3D Printing via Reversible Thia-Michael Reactions.

The development of chemically recyclable polymers for sustainable 3D printing is crucial to reducing plastic waste and advancing towards a circular polymer economy. Here, we introduce a new class of polythioenones (PCTE) synthesized via Michael addition-elimination ring-opening polymerization (MAEROP) of cyclic thioenone (CTE) monomers. The designed monomers are straightforward to synthesize, scalable and highly modular, and the resulting polymers display mechanical performance superior to commodity polyolefins such as polyethylene and polypropylene.

Munsell Soil Colour Prediction from the Soil and Soil Colour Book Using Patching Method and Deep Learning Techniques.

Soil colour is a key indicator of soil health and the associated properties. In agriculture, soil colour provides farmers and advises with a visual guide to interpret soil functions and performance. Munsell colour charts have been used to determine soil colour for many years, but the process is fallible, as it depends on the user's perception.

Mutations in histones dysregulate copper homeostasis leading to defect in Sec61 dependent protein translocation mechanism in Saccharomyces cerevisiae.

The translocation of proteins from the cytoplasm to the endoplasmic reticulum occurs via a conserved Sec61 protein channel. Previously, we reported that mutations in histones cause downregulation of a CUP1 copper metallothionein and copper exposure inhibits the activity of Sec61. However, the role of epigenetic dysregulation on the activity of channel is not clear.

The NE/AAT/CBG axis regulates adipose tissue glucocorticoid exposure.

Corticosteroid binding globulin (CBG; SERPINA6) binds >85% of circulating glucocorticoids but its influence on their metabolic actions is unproven. Targeted proteolytic cleavage of CBG by neutrophil elastase (NE; ELANE) significantly reduces CBG binding affinity, potentially increasing 'free' glucocorticoid levels at sites of inflammation. NE is inhibited by alpha-1-antitrypsin (AAT; SERPINA1).
