Dynamic Polydisulfide Latex via Emulsion Ring‐Opening Polymerization of Cyclodisulfides

open access: yesJournal of Polymer Science, EarlyView.
A polydisulfide latex with a high molar mass was achieved by emulsion polymerization process starting from a dithiol. The mechanism reveals an entropy‐driven ring‐opening polymerization involving disulfide macrocycle intermediates. The polydisulfide particles can be degraded by thiol‐disulfide exchange, and the disulfide fragments can be reengaged in a

Safety, efficacy, pharmacokinetics, and mechanisms of novel 10B‐boronophenylalanine combined with a radio‐frequency quadrupole accelerator in boron neutron capture therapy: A preclinical study in head and neck squamous cell carcinoma

open access: yesPrecision Radiation Oncology, EarlyView.
This study demonstrates that the novel 10B‐BPA‐based BNCT system, combined with an RFQ accelerator, effectively targets head and neck squamous cell carcinoma. It induces tumor regression safely and efficiently by triggering DNA damage and activating the ROS/HIF‐1α/NF‐κB pathway, leading to caspase‐3‐mediated apoptosis.

Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

open access: yesIntegrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

Papain-like cysteine proteases in Nicotiana benthamiana: gene family members and their potential implications in recombinant protein expression

open access: yesFrontiers in Plant Science
IntroductionPapain-like cysteine proteases (PLCPs), characterized by a conserved cysteine residue at their active sites, play crucial roles in plant growth, development, and responses to biotic and abiotic stresses.

Molecular Pharming–Produktion von Biopharmazeutika in Pflanzen

open access: yesBIOspektrum
AbstractThe moss Physcomitrella is a promising production platform for green biopharmaceuticals. To further increase production yields of this platform, we identified terminator sequences to be used in future applications. In addition, we investigated which attributes make a terminator a good choice for biomanufacturing.

Amphibian‐Derived Peptide OA‐AL14 Alleviates UVB‐Induced Skin Photoaging via Autophagy Activation Mediated by the AMPK/mTOR Pathway

open access: yesIntegrative Zoology, EarlyView.
The schematic diagram illustrates that the amphibian‐derived peptide OA‐AL14 protects against UVB‐induced skin photoaging through a dual mechanism: activating the Nrf2 pathway to counteract oxidative stress and modulating the AMPK/mTOR axis to induce protective autophagy. ABSTRACT Skin photoaging, primarily driven by ultraviolet B (UVB) radiation, is a

Analysis of the aspartic protease gene family in Nicotiana benthamiana and its application in recombinant protein expression

open access: yesFrontiers in Plant Science
IntroductionAspartic proteases (APs) play crucial roles in plant growth, stress responses, and protein metabolism. However, endogenous APs in Nicotiana benthamiana, a key plant molecular farming platform, pose a significant challenge by degrading ...

International Guideline on the Diagnosis and Management of Pediatric Patients With Hereditary Angioedema

open access: yesAllergy, EarlyView.
ABSTRACT Hereditary angioedema (HAE) with C1 inhibitor deficiency is a rare disease characterized by unpredictable episodes of tissue swelling (angioedema), which, in most cases, occur first under the age of 18 years, and entail a significant burden of disease not only for the patients but also for their families.

Targeting Immunologic Pathways in Eosinophilic Granulomatosis With Polyangiitis: Translating Emerging Evidence Into Clinical Practice

open access: yesAllergy, EarlyView.
ABSTRACT Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare and potentially life‐threatening systemic, inflammatory disease with multi‐organ manifestations, variable presentation and complex pathology. Multiple interconnected immunological pathways are implicated in EGPA pathology, including a type‐2 immune response driving predominantly ...
