Cartilage‐Penetrating Framework Nucleic Acid Nanoparticles Ameliorate Osteoarthritis by Promoting Drug Delivery and Chondrocyte Uptake

Advanced Science, EarlyView.
Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.

Battling Antibiotic Resistance: Can Machine Learning Improve Prescribing? [PDF]

arXiv, 2019
Antibiotic resistance constitutes a major health threat. Predicting bacterial causes of infections is key to reducing antibiotic misuse, a leading driver of antibiotic resistance. We train a machine learning algorithm on administrative and microbiological laboratory data from Denmark to predict diagnostic test outcomes for urinary tract infections ...

Protamine-like proteins have bactericidal activity. The first evidence in Mytilus galloprovincialis. [PDF]

, 2018
The major acid-soluble protein components of the mussel Mytilus galloprovincialis sperm chromatin consist of the protamine-like proteins PL-II, PL-III and PL-IV, an intermediate group of sperm nuclear basic proteins between histones and protamines.

LIMK1 as a Novel Kinase of β‐Catenin Promotes Esophageal Cancer Metastasis by Cooperating With CDK5

Advanced Science, EarlyView.
Li et al. innovatively map the kinase‐substrate network in esophageal cancer metastasis. Their study demonstrates that LIM domain kinase 1 (LIMK1) and Cyclin‐dependent kinase 5 (CDK5) synergistically increase the phosphorylation of β‐catenin, thereby activating the Wnt/β‐catenin signaling pathway to promote esophageal cancer metastasis.

Immobilization of doxorubicin on the olygoelectrolytic polymeric carrier VEP-GMA-PEG increases its and anticancer activity cellular uptake

Біологічні студії, 2012
Application of special systems for drug delivery into target cells might be useful for overcoming several problems in treatment of dangerous diseases. These are: consequences of nonspecific negative effects of drugs towards healthy cells, low sensitivity

Antimicrobial resistance and use, and rates of hospitalization associated with bacterial infections, including sepsis [PDF]

arXiv, 2018
While the mechanisms and quantitative details are complex, few analysts would doubt that antibiotic use increases the prevalence of drug-resistant bacterial pathogens among all bacteria causing disease in a population. The causal connection between antibiotic use and the total incidence of severe bacterial infections, possibly mediated by antibiotic ...

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

Advanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,

On‐Demand Ligate and Release Strategy Based on Photoclick Reaction in Tandem with Pd‐Mediated Deallylation

Angewandte Chemie, EarlyView.
A consecutive, controllable, and revertible new‐to‐nature ligation and cleavage strategy has been rationally devised to selectively visualize and manipulate biomolecules of interest. The photoclick cycloaddition between allenyl phenyl ether motifs and 9,10‐phenanthrenequinone analogues installed a terminal allyl handle at the exocyclic site, thereby ...

Non-autonomous Cellular Responses to Ototoxic Drug-Induced Stress and Death

Frontiers in Cellular Neuroscience, 2017
The first major recognition of drug-induced hearing loss can be traced back more than seven decades to the development of streptomycin as an antimicrobial agent.

Neutrophil‐Mimicking Nanomedicine Eliminates Tumor Intracellular Bacteria and Enhances Chemotherapy on Liver Metastasis of Colorectal Cancer

Advanced Science, EarlyView.
Fusobacterium nucleatum (Fn) enrichment has been identified in colorectal cancer and its liver metastases. This study develops neutrophil‐mimicking nanoparticles with multiple targeting capabilities encapsulating metronidazole and oxaliplatin for antibacterial and anticancer purposes. This approach reverses the epithelial mesenchymal transition process
