Abstract Pseudomonas aeruginosa is a bacterium producing industrially utile metabolites, such as rhamnolipids, biopolymers, and pigments. Pyocyanin, the most studied example of pigments, virulence factor that also shows potential for application in, e.g., agriculture, anticancer therapy, energy production. Therefore, inhibitors stimulants pyocyanin production by P. should be studied, nanomateri...

THE nature of the cell wall constituents of the red and brown algae has been the subject of study in this laboratory for some time past [Haas and Hill, 1921; Haas, 1921; Russell-Wells, 1922; Haas and Russell-Wells, 1923, 1929]. The present investigation, which is concerned primarily with Laminaria spp., was undertaken with the object of throwing some light on the mode of occurrence within the p...

A classic method for the encapsulation and culture of chondrocytes in alginate beads is described. Chondrocytes are released from cartilage matrix by collagenase/dispase digestion and mixed with a solution of 1.25% alginic acid until a homogenous suspension is obtained. The suspension is drawn into a syringe and pushed gently through a needle, so that drops fall into a solution of calcium chlor...

Algae are eaten as health food in many Asian countries. We summarize our recent results regarding the immunoregulatory role of polysaccharides from edible algae on delayed-type hypersensitivity (DTH) and antitumor immune responses using mice. These algae are divided into two types; those which manipulate immune responses through toll-like receptor 4 (TLR 4), and those which use different recept...

All-inorganic perovskite nanocrystals (NCs) have attractive potential for applications in display and lighting fields due to their special optoelectronic properties. However, they still suffer from poor water thermal stability. In this work, green CsPbBr3-alginic acid (CsPbBr3-AA) composites were synthesized by an situ hot-injection process which showed a high photoluminescence quantum yield (P...
