Application of bacteriophages in the prevention of Bacillus cereus infection in potatoes

Background The main component of potatoes is starch, which can serve as an easy breeding ground for Bacillus cereus during storage. This can decrease the shelf life of potatoes and pose food safety issues. Methods This study isolated several strains of B. cereus from rotten potat...

Rapid Identification of Fritillaria Bulbus Botanical Origins and Adulteration by Thermal‐Assisted Plasma Ionization Time‐of‐Flight Mass Spectrometry Coupled With Chemometrics

ABSTRACT Fritillaria Bulbus (FB) is a valuable traditional Chinese medicine with diverse pharmacological activities. Due to economic incentives, high‐quality FBs are frequently adulterated with morphologically similar counterfeit species in commercial markets. A rapid analytical...

Production activity and resulting pollution, not depth, driven microbial community structure, function, and assembly mechanisms in an aged petroleum hydrocarbon contaminated soil

The degradation activity of soil microorganisms remains a crucial pathway for the reduction of petroleum hydrocarbons (PHs) pollutants in industrial site soils. Stimulating the metabolic activity of indigenous soil microorganisms to achieve pollutant removal is a promising remedi...

Fluorine‐Driven Interfacial Reconfiguration for pH‐Universal CO 2 Electrolysis at High Current Densities via Enhanced CO 2 Enrichment and Proton Feeding

ABSTRACT High‐rate CO 2 electroreduction is challenged by the conflict between sluggish CO 2 activation and hydrogen evolution at high currents, particularly under pH‐universal and dilute CO 2 conditions. In this study, a defective fluorine‐modified bismuth (F‐Bi) with electron‐r...

Growth and electrical transport property studies of Bi2Se3 thin films with Cr or MnPc surface magnetic modification

The Bi2Se3 family is widely regarded as the prototypical three-dimensional topological insulator, which is an ideal platform for investigating topological quantum phenomena such as the quantum anomalous Hall effect and Majorana fermions. Further application requires high-quality...

Effect of roasting conditions on the aroma characteristics of Fenghuang Dancong oolong tea (Yashixiang)

Background Roasting is a crucial refining process for Fenghuang Dancong (FHDC) tea, imparts diverse aroma profiles to the final products. Yashixiang (YS) tea is the most popular FHDC variety among consumers. Methods This study identified the aroma-active compounds (AACs) of YS te...

Decoding fat-driven appetite: implications for flavor science and health-oriented food design

Fat perception engages overlapping neurobiological pathways—spanning taste, texture, and gut–brain signaling—that encode reward, incentive salience, and energy-balance feedback. In obesity, these circuits become dysregulated, amplifying maladaptive eating. Deciphering these mecha...

Carboxyl Amidation of Chlorogenic Acid Improves Anti-Inflammatory Activity and Biosafety via Potent AKR1B1 Inhibition in LPS-Induced Macrophages

Persistent inflammation driven by excessive AKR1B1 activation contributes to the progression of multiple chronic inflammatory diseases. Natural chlorogenic acid (CGA) exhibits anti-inflammatory activity but suffers from poor membrane permeability, while its laurate ester derivati...

Active Electrochemical Regulation Strategies Based on Dynamic Response Mechanisms for Secondary Batteries

Developing advanced secondary batteries to adapt to the increasingly stringent performance requirements demands a fundamental rethinking of battery regulation strategies. Active electrochemical regulation strategies for secondary batteries are an innovative shift from static mate...

Increased receptor binding and spike glycosylation, remodeled immune escape of surging SARS-CoV-2 subvariant BA.3.2.2/RE.2.2/Cicada

SARS-CoV-2 continues to evolve. The subvariant BA.3.2 (Cicada), a derivative of the Omicron BA.3 subtype first detected in late 2024, harbors multiple spike protein mutations, ORF7 and ORF8 deletions, and has recently evolved sublineages (BA.3.2.1 and BA.3.2.2), rendering it a cr...

Yeast Protein-Derived Peptides Protect against Ethanol-Induced Acute Gastric Mucosal Injury: Isolation, Identification, and Potential Mechanisms

Abstract Ethanol-induced gastric mucosal injury (AGMI) is intrinsically linked to oxidative stress, inflammatory responses, and compromised mucosal defense. This study aimed to isolate bioactive peptides from yeast protein (YP) and elucidate these in vitro protective mechanisms a...

Radical‐Integrated Phosphorus‐Containing Ionic Organic Cage for Efficient Gold Recovery From Complex Liquids

ABSTRACT The development of advanced adsorbents for the selective and efficient recovery of gold from complex aqueous matrices is of paramount importance for sustainable resource recycling. Here, we report a phosphorus‐functionalized, quaternized ammonium cages (Phos‐QA‐Cage‐Cl)...

Extracellular matrix remodeling upregulates hippocampal neurogenic niche stiffness and impairs neurogenesis in Alzheimer's disease

Abstract INTRODUCTION Preserving adult hippocampal neurogenesis alleviates cognitive deficits in Alzheimer's disease (AD), yet how biophysical alterations in such as stiffness in the neurogenic niche regulate neurogenesis remains unclear. METHODS Stiffness in the hippocampal dent...

Tribochemical and tribomechanical effect of TiO 2 nanoparticle: Different influence on MoDTC and ZDDP additives

Abstract This study investigates the formulation-dependent tribochemical regulation of TiO2 nanoparticles in molybdenum dithiocarbamate (MoDTC), zinc dialkyldithiophosphate (ZDDP), and their blended lubricant systems. Reciprocating ball-on-disk tribological tests were conducted u...
