Development of an in situ small intestinal injection technique for targeted macromolecule delivery and in vivo functional studies in mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study developed a minimally invasive, in situ small intestinal injection technique for mice, enabling targeted delivery of bioactive molecules while bypassing gastric degradation. Validation using functional assays and single‐cell RNA sequencing reveals high‐mobility group box 1–mediated epithelial responses, offering a translational tool for gut ...

When Does Alzheimer's Disease Start? Plasma Aβ42/40 Assays Show Steep Changes at Aβ‐PET Centiloid 15, Mean Age of 66 Years

open access: yesAnnals of Neurology, EarlyView.
Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...

Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

open access: yesAnimal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

Enhanced deoxyviolacein bioproduction via enzyme condensation with a yeast glycolytic enzyme‐derived peptide tag

open access: yesBiotechnology Progress, EarlyView.
Fusion of a 27‐amino‐acid peptide tag derived from a glycolytic enzyme enabled artificial assembly formation of the two violacein biosynthetic enzymes, VioE and VioC. This assembly resulted in enhanced biosynthesis of deoxyviolacein. Abstract In microbial production, regulating endogenous and exogenous synthetic pathways is essential.

Extreme free energy of stabilization of Taq DNA polymerase

open access: yesProteins: Structure, Function, and Bioinformatics, 2004
AbstractWe have examined the chemical denaturations of the Klentaq and Klenow large‐fragment domains of the Type 1 DNA polymerases from Thermus aquaticus (Klentaq) and Escherichia coli (Klenow) under identical solution conditions in order to directly compare the stabilization energetics of the two proteins.

Association Between D‐amino Acids in Natto (fermented soybeans) and Kidney Dysfunction

open access: yesChemFoodChem, EarlyView.
XX XX ABSTRACT In this study, we examined clinical and cohort data to explore the potential renoprotective effects of natto (fermented soybeans) consumption and its relationship with D‐amino acids. In a clinical study, ten healthy adults consumed one 40‐g pack of natto three times in a single day, and plasma and urine samples were collected 1 h and 24 ...

Evolved DNAzymes and Stable Activation Chemistry Enable High‐Efficiency DNA Ligation

open access: yesChemistry – A European Journal, EarlyView.
In vitro selection of pre‐structured DNA libraries and chemical screening of alternative activation groups yielded trans‐acting DNAzymes with faster ligation rates and enhanced DNA substrate stability. The combination of C3S1 DNAzymes and phosphobenzimidazole‐activated DNA substrates provides improved DNA ligation performance, offering promise for ...
