Relapse prevention remains a major challenge to smoking cessation efforts. T. H. Brandon, B. N. Collins, L. M. Juliano, and A. B. Lazev (2000) found that a series of 8 empirically based relapse-prevention booklets mailed to ex-smokers over 1 year significantly reduced relapse. This study dismantled 2 components of that intervention: the amount of content (number of booklets) and the frequency of contact. Content and contact were crossed in a 2 X 2 factorial design. The criteria of at least 1 week of abstinence at baseline was met by 431 participants, 75%-85% of whom returned 12-, 18-, and 24-month follow-up questionnaires. Eight booklets produced consistently higher point-prevalence abstinence rates than did a single booklet, but frequency of contact did not affect outcome. Moreover, the high-content interventions were highly cost-effective.

The synthesis of degradable polymer prodrug nanoparticles is still a challenge to be met, which would make it possible to remedy both the shortcomings of traditional formulation of preformed polymers (, low nanoparticle concentrations) and those of the physical encapsulation of drugs (, burst release and poor drug loadings). Herein, through the combination of radical ring-opening polymerization (rROP) and polymerization-induced self-assembly (PISA) under appropriate experimental conditions, we report the successful preparation of high-solid content, degradable polymer prodrug nanoparticles, exhibiting multiple drug moieties covalently linked to a degradable vinyl copolymer backbone. Such a rROPISA process relied on the chain extension of a biocompatible poly(ethylene glycol)-based solvophilic block with a mixture of lauryl methacrylate (LMA), cyclic ketene acetal (CKA) and drug-bearing methacrylic esters by reversible addition fragmentation chain transfer (RAFT) copolymerization at 20 wt% solid content.

Cellulose-derived biomaterials offer a sustainable and versatile platform for various applications. Enzymatic engineering of these fibers, particularly using lytic polysaccharide monooxygenases (LPMOs), shows promise due to the ability to introduce functional groups onto cellulose surfaces, potentially enabling further functionalization. However, harnessing LPMOs for fiber engineering remains challenging, partly because controlling the enzymatic reaction is difficult and partly because limited information is available about how LPMOs modify the fibers.

Biocrude derived from biomass via hydrothermal liquefaction (HTL) is a sustainable substitute for petroleum to obtain energy and biochemicals. Upgrading biocrude inevitably faces the trade-off between consuming large amounts of hydrogen via hydrotreating and high yield of solid residue without additional hydrogen. In this work, we report a non-hydrogenated refinery paradigm for nearly complete valorization (~90%), via co-generating green coal and bio-lubricant.

The secretion of glucagon-like peptide-1 (GLP-1) is promoted by various nutrients, and glucose and fructose stimulate GLP-1 secretion via intracellular metabolism. D-Allulose (allulose), a non-metabolizable epimer of D-fructose, is also effective in stimulating GLP-1 secretion, although its underlying mechanism remains unclear. We previously observed intestinal distension after the oral administration of allulose, accompanied by increased GLP-1 secretion in rats, possibly because of the low or slow absorbability of allulose.
