Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Integrated spherical nucleic acid nanoreactor mobilizes targeted PD‐L1 proteolysis and cuproptosis for robust breast cancer immunotherapy

BMEMat, EarlyView.
This study provides an integrated spherical nucleic acid nanoreactor (denoted as AMCuD) for targeted PD‐L1 degradation and chemo‐dynamically enhanced cuproptosis to synergically elicit robust immunotherapy against the triple‐negative breast cancer (TNBC) growth, recurrence and metastasis.

A widespread peroxiredoxin-like domain present in tumor suppression- and progression-implicated proteins. [PDF]

, 2010
Background Peroxide turnover and signalling are involved in many biological phenomena relevant to human diseases. Yet, all the players and mechanisms involved in peroxide perception are not known.

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

Biological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Selection, establishment and characterization of cell lines derived from a chemically-induced rat mammary heterogeneous tumor, by flow cytometry, transmission electron microscopy, and immunohistochemistry

, 2000
In order to isolate, characterize, and establish culture cell lines with different diagnostic and prognostic significance, derived from multiclonal neoplasms, a ductal infiltrating mammary tumor was induced in rats by 7,12-dimethylbenz[a]anthracene ...

Chemotherapeutic Potential of Fluorouracil‐Platinum (IV) Prodrugs Against Cisplatin‐Resistant Colorectal Cancer Cells

Chemistry – A European Journal, EarlyView.
ABSTRACT Fluorouracil‐platinum(IV) prodrugs represent a novel class of multimechanistic chemotherapeutics with enhanced anticancer potential. The prodrugs PtIVP‐5FUMeOBut and PtIV56‐5FUMeOBut were actualized by derivatising the clinical drug 5‐fluorouracil (5FU) and coordinating it to platinum(IV) complexes, leveraging the established cytotoxicity of ...

The altered tumoricidal capacity of macrophages isolated from tumor-bearing mice is related to reduce expression of the inducible nitric oxide synthase gene.

, 1996
Nitric oxide (NO) is a major effector molecule in the destruction of tumor cells by activated macrophages. However, in many cases, developing neoplasms appear to be capable of impairing steps in the complex process leading to NO production as a means of ...

Synthesis and Characterization of Novel Silylated Sm3+ and Eu3+ Complexes Incorporated Into Mesoporous Silica Nanoparticles

European Journal of Inorganic Chemistry, EarlyView.
The strategy of incorporating the Eu(tta‐Si)3(phen) and Sm(tta‐Si)3(phen)2 complexes prevented leaching of the complexes and preserved their intrinsic optical properties. Preliminary studies of silylated Ln3+ complexes and nanoparticles loaded with these complexes demonstrated cytotoxicity against cancer cells, with minimal cytotoxic effect on nontumor

Strategic construction of fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents for amplifying cancer phototheranostics

FlexMat, EarlyView.
The development of conventional phototheranostic nanomedicines suffers from an intrinsic trade‐off between NIR‐II fluorescence emission and phototherapeutic effects, leading to poor overall efficacy. Herein, we propose an innovative fluorination strategy by constructing fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents to ...
