NIR Light‐Driven Photocatalytic Antibacterial Hydrogels for Synergistic MRSA Biofilm Eradication and Wound Regeneration

Advanced Science, EarlyView.
The nanohybrid hydrogel (Fe‐BOS@C/H Gel) is composed of Fe‐Bi2O2‐XS (Fe‐BOS) photocatalysts and CS‐ADH/OHA (C/H) hydrogel. Fe‐BOS photocatalysts achieve near‐infrared (NIR) light‐driven antibacterial photocatalytic/mild photothermal therapy (APCT/MPTT), effectively eliminating methicillin‐resistant Staphylococcus aureus (MRSA) biofilms. The degradation

Effect of Increased Temperature on Native and Alien Nuisance Cyanobacteria from Temperate Lakes: An Experimental Approach

Toxins, 2018
In response to global warming, an increase in cyanobacterial blooms is expected. In this work, the response of two native species of Planktothrix agardhii and Aphanizomenon gracile, as well as the response of two species alien to Europe— ...

Peptide and Protein Hydrogels [PDF]

, 2012
Proteins are a fascinating class of macromolecules from both functional and structural perspectives. They catalyze the reactions that sustain life, bind ligands with high affinity and specificity, and mediate interactions among biomolecules in complex ...

Higher‐Level Structural Classification of Pseudomonas Cyclic Lipopeptides through Their Bioactive Conformation

Advanced Science, EarlyView.
Solution structures of a series of cyclic lipodepsipeptides from Pseudomonas reveal that these specialized metabolites adopt left‐handed alpha helical conformations of only two types, being either ‘stapled’ or ‘catch‐pole’ helix. The particular modular distribution of the biosynthetic gene clusters is found to determine the extent of their conserved ...

Transport Deficiency Is the Molecular Basis of Candida albicans Resistance to Antifungal Oligopeptides

Frontiers in Microbiology, 2017
Oligopeptides incorporating N3-(4-methoxyfumaroyl)-L-2,3-diaminopropanoic acid (FMDP), an inhibitor of glucosamine-6-phosphate synthase, exhibited growth inhibitory activity against Candida albicans, with minimal inhibitory concentration values in the 0 ...

Bioactive oligopeptides in dermatology: Part I [PDF]

Experimental Dermatology, 2012
AbstractShort sequence amino acids or oligopeptides represent a relatively new and promising area of dermatology. Oligopeptides are defined as peptide sequences ranging from 2 to 20 amino acids. This class of proteins includes potent biologically active compounds, which can modulate various cellular and molecular processes.

Intravenous lanadelumab for the treatment of moderately ill COVID‐19 patients

British Journal of Clinical Pharmacology, EarlyView.
Aims Kallikrein‐kinin system (KKS) dysregulation is hypothesized to play a pathogenetic role in COVID‐19‐associated pulmonary oedema. To investigate the efficacy and safety of intravenous lanadelumab, a monoclonal antibody that inhibits plasma kallikrein, in COVID‐19, we conducted a phase 2, open‐label, randomized‐controlled, proof‐of‐concept ...

Homochiral oligopeptides by chiral amplification: Interpretation of experimental data with a copolymerization model

, 2012
We present a differential rate equation model of chiral polymerization based on a simple copolymerization scheme in which the enantiomers are added to, or removed from, the homochiral or heterochiral chains (reversible stepwise isodesmic growth or ...

Three Oligopeptide-binding Proteins Are Involved in the Oligopeptide Transport of Streptococcus thermophilus [PDF]

Journal of Biological Chemistry, 2002
The functions necessary for bacterial growth strongly depend on the features of the bacteria and the components of the growth media. Our objective was to identify the functions essential to the optimum growth of Streptococcus thermophilus in milk. Using random insertional mutagenesis on a S. thermophilus strain chosen for its ability to grow rapidly in
