Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

Fermented Lacticaseibacillus Paracasei Cultures Ameliorate Colitis by Modulating Microbiota‐Derived Tryptophan Metabolism and Macrophage Polarization

Advanced Science, EarlyView.
A solid‐state fermented probiotic (PYW) is developed using wheat bran as substrate, containing high viable Lacticaseibacillus paracasei and bioactive metabolites. PYW alleviates intestinal inflammation by gut microbiota composition, enriching indole derivatives, activating aryl hydrocarbon receptor signaling, and regulating macrophage polarization. PYW

Preparation and properties of α-amylase immobilized on silk fibroin

浙江大学学报. 农业与生命科学版, 2002
Cavernous basified fibroin was prepared from degumed silk which pretreated with dilute alkali solution and served as supporter for immobilization of α-amylase to form the basified fibroin immobilized α-amylase, BFIA.

IL‐4/STAT6‐signaling Influences Local Inflammation and Regeneration Processes During Acute Pancreatitis and Promotes Fibrosis by a Direct Activation of Pancreatic Fibroblasts During Chronic Pancreatitis

Advanced Science, EarlyView.
IL‐4/IL‐13/STAT6 signaling plays a crucial for the suppression of pro‐inflammation during acute pancreatitis and supports acinar cell regeneration but has only minor impact on fibrogenesis during chronic form of the disease. IL‐4/IL‐13 induce the expression of certain collagens directly in pancreatic fibroblasts via STAT6 activation, whereas ...

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

Advanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.
