Changes in the hemolytic activity of Candida species by common electrolytes

BMC Microbiology, 2015
BackgroundHemolysins are crucial virulence factors which help pathogens to survive and persist in the host. This study investigated whether common electrolytes will affect the hemolysins of Candida species.

An In Situ Embedded B‐MOF Sponge With Shape‐Memory for All‐in‐One Diabetic Wound Therapy

Advanced Healthcare Materials, EarlyView.
A smart shape‐memory sponge dressing (P1A3@B‐MOF) is developed for accelerated diabetic wound healing. It achieves pH‐responsive corelease of Zn2+ and salvianolic acid B, synergistically providing antibacterial action, repolarizing macrophages to the M2 phenotype, and promoting angiogenesis.

Comparative study of hemolytic activity of Bordetella species

Iranian Journal of Microbiology, 2009
Background and objectives: Bordetella species colonize the respiratory tract of mammals and thereby cause the whooping cough. Most of the species produce adenylate cyclase - a toxin ( hemolysin ) responsible for increasing intracellular cyclic AMP (cAMP)

Membrane-Pore Forming Characteristics of the Bordetella pertussis CyaA-Hemolysin Domain

Toxins, 2015
Previously, the 126-kDa Bordetella pertussis CyaA pore-forming/hemolysin (CyaA-Hly) domain was shown to retain its hemolytic activity causing lysis of susceptible erythrocytes. Here, we have succeeded in producing, at large quantity and high purity, the

Studies of hemolytic staphylococci: Hemolytic activity--biochemical reactions--serologic reactions [PDF]

Journal of Infectious Diseases, 1922
That staphylococci lake blood was brought out in 1900, when Kraus 1 noticed the hemolytic effect of staphylococci on bloodplates. The following year Neisser and Wechsberg2 demonstrated a hemolytic substance in filtrates of broth cultures. They found that in alkaline beef broth, this hemolytic substance began to appear on the fourth day and reached a ...

Why does the hemolytic activity of silica predict its pro-inflammatory activity?

Particle and Fibre Toxicology, 2014
The hemolytic activity of inhaled particles such as silica has been widely investigated in the past and represents a usual toxicological endpoint to characterize particle reactivity despite the fact that red blood cells (RBCs) are not involved in the ...

Zinc‐Containing Bioactive Glass Programs Macrophage Polarization through Extracellular Traps Regulation for Enhanced Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
Zinc‐containing bioactive glass (ZnBG) promotes diabetic wound healing by regulating macrophage extracellular traps (METs). Specifically, ZnBG reduces oxidative stress and inhibits the PAD4 and NLRP3/caspase‐1/GSDMD signaling pathways, thereby suppressing MET formation.

[Vibrio cholerae hemolytic activity].

Zhurnal mikrobiologii, epidemiologii i immunobiologii, 2007
Mechanisms of realization of Vibrio cholerae hemolytic activitywere analyzed using summarized own results and data from the literature. It has been shown that lectin receptor, which coded by hlyA gene, participates in lysis of sheep erythrocytes, but not of rabbit erythrocytes, as well as interact with D-galactose with selectivity to 3 anomers.

Nb2C‐Reinforced Hydrogel Microneedle as Dual ROS‐Scavenging Platform to Promote Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
An advanced microneedle patch integrating niobium carbide nanosheets and curcumin is engineered for diabetic wound healing. The system enables dual ROS scavenging and NIR‐enhanced antimicrobial activity, effectively rebalancing the oxidative microenvironment, promoting macrophage repolarization and angiogenesis, and accelerating full‐thickness wound ...
