DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

open access: yesSmall, EarlyView.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

Regulatory Mechanism of Amylase Secretion in Rat Parotid Glands

open access: yes, 1985
P(論文)It is known that a diurnal cycle in amylase activity of rat parotid glands is present. This cycle is correlated with the nocturnal eating habits of rats.

Anti-diabetic effect of rice extract constituents through the molecular inhibition of α-amylase and α-glucosidase activity

open access: yes
Carbohydrate digestive enzymes like α-amylase and α-glucosidase can be used to treat and manage diabetes. By inhibiting these enzymes, carbohydrate digestion slowed down, lowering the level of glucose entry into the bloodstream and preventing ...

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

Determination of α-Amylase Enzyme Activity and Blood Glucose Level in Local Duck

open access: yesAnimal Production: Indonesian Journal of Animal Production, 2003
A α-amylase is included in hydrolase’s enzyme (E.C. 3.2.1.3), which catalyzed the breaking down of α-1,3-glycosidic bound on amylase chain and produced glucose as end product.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Entrapment of glucoamylase by sol-gel technique in PhTES/TEOS hybrid matrixes

open access: yes, 2007
Mesoporous silica particles were prepared by the sol-gel method from different alkoxysilane precursors and used as a host matrix for encapsulation of glucoamylase, an enzyme widely used in fermentative industry.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Update on Non‐Biological and RNA‐Based Therapeutics in Chronic Inflammatory Diseases: Precision Medicine Through Small Molecules: An EAACI Position Paper

open access: yesAllergy, EarlyView.
ABSTRACT In the last decades, critical advancements in research technology and knowledge on disease mechanisms steered therapeutic approaches for chronic inflammatory diseases towards unprecedented target specificity. For allergic and chronic lung diseases, biologic drugs pioneered this goal, acquiring on the way—through the clinical use of monoclonal ...
