Dexime: A Selectively Enzyme‐Degradable Hydrogel for Protein Therapeutic Release

Advanced Materials, EarlyView.
A dextrin‐oxime hydrogel (dexime) is produced using ketone or aldehyde modified dextrin and tetra‐oxyamine modified poly(ethylene glycol). The rheological and mechanical properties of dexime are tunable. Dexime is injectable, cytocompatible, hydrolytically stable, and selectively degradable by α‐amylase.

Gut Microbiota Regulates Systemic Inflammatory Response and Compensatory Anti‐Inflammatory Response Syndromes by Targeting PF4+ Macrophages in Acute Pancreatitis

Advanced Science, EarlyView.
ABSTRACT Acute pancreatitis (AP) begins with pancreatic local inflammation, leading to the onset of systemic inflammatory response syndrome (SIRS), followed by compensatory anti‐inflammatory response syndrome (CARS), which causes immune paralysis and higher mortality rate.

Potential anti-hyperglycemic activity of black tea theaflavins through inhibiting α-amylase

Food Chemistry: X
Hyperglycemia can cause early damage to human bady and develop into diabates that will severely threaten human healthy. The effectively clinical treatment of hyperglycemiais is by inhibiting the activity of α-amylase.

Biochemical characterization of α-amylase from the yeastCryptococcus flavus [PDF]

FEMS Microbiology Letters, 2004
During our screening of amylolytic microorganisms from Brazilian fruits, we isolated a yeast strain classified as Cryptococcus flavus. When grown on starch-containing medium this strain exhibited the highest amylase production after 24 h of cultivation. The extracellular amylase from C.

Integration of Spatiotemporal Multi‐Omics in Peach Fruit Unravels a Metabolic Niche and the Genetic Basis of Trichome‐Mediated Stress Adaptation

Advanced Science, EarlyView.
This study constructed the first spatiotemporal multi‐omics map of peach fruit and discovered a key candidate gene that synergistically regulates trichome development and drought tolerance through the jasmonic acid signaling pathway, providing insights into the coupling mechanism between development and stress resistance.

Cloning of a thermostable α-amylase gene fromBacillus licheniformisand its expression inEscherichia coliandBacillus subtilis [PDF]

FEMS Microbiology Letters, 1984
The gene coding for the thermostable α-amylase Bacillus licheniformis has been isolated from a direct shotgun in Escherichia coli using the bacteriophage lambda as a vector. The fragment containing the α-amylase gene has been sub-cloned in pBR322 and its restriction map determined. The α-amylase produced by the E.

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

Advanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Production and biochemical characterization of an α-amylase from the moderate halophileHalomonas meridiana [PDF]

FEMS Microbiology Letters, 2000
Extracellular amylase production by the moderate halophile Halomonas meridiana was optimized and the enzyme was characterized biochemically. The highest amylase production was achieved by growing H. meridiana cultures in media with 5% salts and starch, in the absence of glucose until the end of the exponential phase.
