In Situ Synthesis of a Tumor Microenvironment‐Activated Radiosensitizing Cu2‐xS/LDH Probe for Photoacoustic Imaging‐Guided Radiotherapy

Advanced Science, EarlyView.
We reported a new kind of organic‐inorganic composite nanomaterial with excellent PA imaging performance after the in situ activation by hydrogen sulfide in colorectal cancer tissues, which was used for precise radiotherapy of colorectal cancer. It shows a great application potential for early diagnosis and treatment of tumor.

Thiocysteine lyases as polyketide synthase domains installing hydropersulfide into natural products and a hydropersulfide methyltransferase

Nature Communications, 2021
Enzymes installing an intact hydropersulfide (-SSH) group into natural products have so far not been identified. Here, the authors report the characterization of an S-adenosyl methionine-dependent hydropersulfide methyltransferase (GnmP) for ...

Quantification of Single‐Cell Cysteine Using an Electrochemical Nanosensor for Predicting Tumor Disulfidptosis Susceptibility

Advanced Science, EarlyView.
Cysteine attracts interest due to its unique electrochemical activity and emerging relationship with disulfidptosis. This study develops a new electrochemical nanosensor, which represents the first of its kind capable of detecting intracellular cysteine for various types of tumor cells and primary tumor cells in mice to evaluate disulfidptosis ...

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, EarlyView.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

APE1 Activity is Controlled by Non‐G‐Quadruplex Conformations in Single‐ and Double‐Stranded G‐Quadruplex Constructs

Chemistry – A European Journal, EarlyView.
G‐quadruplex (G4) folding in DNA is inhibitory to AP endonuclease, although the protein still binds well to G4s. Curiously, partially folded G‐rich sequences, possibly transient hairpins, containing AP are very good substrates for cleavage by APE1. Herein, the enzyme activity and G4 folding are studied in single‐stranded vs. duplex contexts.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

ESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Screening and identification of marine alginate lyase-producing bacteria and optimization of enzyme production conditions [PDF]

Zhongguo niangzao
Alginate lyases are mostly derived from marine bacteria with unique living environments. Using sodium alginate as the sole carbon source, a strain with high-yield alginate lyase from 56 strains of marine bacteria was screened using primary screening by ...
