Abstract BACKGROUND Bioactive peptides derived from protein hydrolysates provide various health benefits; however, their practical application is limited by low gastrointestinal stability, enzymatic degradation, and poor intestinal absorption. Overcoming these challenges remains a key bottleneck for oral peptide delivery.

ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...

A Non‐Antigenic Randomized Polyethylene Glycol/Poly(2‐Phenyl‐2‐Oxazine)‐Based Drug Delivery Platform
Randomized PEG (rPEG), a conceptually new PEG alternative, is combined with poly(2‐phenyl‐2‐oxazine) (PPheOzi) to establish an rPEG‐b‐PPheOzi‐b‐rPEG micellar drug delivery platform. The PPheOzi block enables high drug loadings, while competitive ELISA reveals a drastic reduction in anti‐PEG antibody affinity of rPEG in comparison to PEG.

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.
