Critical Melting–Freezing Pretreatment Enhances Enzymatic Hydrolysis for Porous Starch Preparation: Role of Partial Structural Weakening and Surface Modification

Foods
In this study, critical melting followed by freeze–thaw (CMFT) pretreatment was employed as an effective strategy to partially weaken and modify the surface structure of starch, enhancing enzymatic hydrolysis (EH) for porous starch preparation.

A Bifunctional T3SS‐Effector Simultaneously Cleaves Host MAP Kinase and Inhibits PPM1A Phosphatase

Advanced Science, EarlyView.
Pathogenic bacteria exploit the metalloprotease effector NleD to subvert host defenses. Structural, biochemical, and infection analyses reveal a bifunctional mechanism by which NleD binds and inhibits the host phosphatase PPM1A while preserving its proteolytic activity against MAPKs.

Enzymatic hydrolysis of "Polydextrose".

Journal of the Japanese Society of Starch Science, 1989
「ポリデキストロース」(PD)の各種グルカナーゼによる分解性を,とくに多量の酵素で長時間作用させた場合について検討した.その結果,PDは各種α 一アミラーゼ,セルラーゼによって2～3%程度の分解を受けた.イソマルトデキストラナーゼ,グルコデキストラナーゼによっては8～10%程度分解され,また高濃度のグルコァミラーゼでは20%分解された.この結果に基づいてPDの構造について推論した. 本研究にあたり,貴重な精製酵素標品を恵与された静岡大学教育学部岡田嚴太郎教授に深謝する.またPD試料,または酵素を提供されたファイザー,ノボ・インダストリージャパン,キリンピールの各社に感謝する.

Understanding and Overcoming Antibody‐Drug Conjugate Resistance: Biological Mechanisms and Emerging Analytical Frameworks in Breast Cancer

Advanced Science, EarlyView.
Antibody–drug conjugates (ADCs) transform breast cancer therapy, yet resistance limits their durability. Emerging evidence reveals that ADC failure is not solely tumor‐intrinsic but shaped by dynamic tumor–microenvironment interactions that alter drug delivery, processing, and response.

Multi‐Enzyme Mimetic Molybdenum Nitride Nanozymes Reshape Subgingival Microenvironment for Synergistic Periodontitis Therapy via ROS Regulation and Microbiome Remodeling

Advanced Science, EarlyView.
ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...
