  • As we all know, ceramic materials are inorganic, non-metallic, solid, and inert materials. Things are made from them by the action of heat and subsequent cooling, which may be crystalline or partly crystalline. The definition of ceramic is often restricted to inorganic crystalline materials, as opposed to the noncrystalline glasses, which involve several steps of the ceramic process, and their mechanical properties behave similarly to ceramic materials.

  • A 6A,6A¢-dicyclohexylamine-6B,6B¢-diselenide-bis-b-cyclodextrin (6-CySeCD) was designed and synthesized to imitate the antioxidant enzyme glutathione peroxidase (GPX). In this novel GPX model,b-cyclodextrin provided a hydrophobic environment for substrate binding within its cavity, and a cyclohexylamine group was incorporated into cyclodextrin in proximity to the catalytic selenium in order to increase the stability of the nucleophilic intermediate selenolate.

  • Retinoid-binding proteins are indispensable for visual cycles in both vertebrate and invertebrate retinas. These proteins stabilize and transport hydrophobic retinoids in the hydro-philic environment of plasma and cytoplasm, and allow regeneration of visual pigments. Here, we identified a novel retinol-binding protein in the eye of a butterfly, Papilio xuthus. The protein that we term Papilioretinol-binding protein (PapilioRBP) is a major component of retinal soluble proteins and exclusively binds 3-hydroxyretinol, and emits fluorescencepeakingat 480 nmunder ultraviolet (UV) illumination. ...

  • Smart polymers are macromolecules capable of undergoing rapid, reversible phase transitions from a hydrophilic to a hydrophobic microstructure. These transitions are triggered by small shifts in the local environment, such as slight variations in temperature, pH, ionic strength, or the concentration of specific substances like sugars. Smart polymers have an extensive range of applications, but this book focuses solely on their roles within the fields of bioseparation and biomedicine. Until recently, polymers were considered to be passive participants within these fields.

  • Serum- and glucocorticoid-induced protein kinase-1 (SGK-1) plays a crit-ical role in regulation of the epithelial sodium channel, ENaC. SGK-1 also shares significant catalytic domain homology with protein kinase B (PKB⁄AKT-1) and is a downstream effector of antiapoptotic phosphoinos-itide 3-kinase signaling.
