Recently, tissue engineering, including 3D bioprinting of the pancreas, has acquired clinical significance and has become an outstanding potential method of customized treatment for type 1 diabetes mellitus. The study aimed to evaluate the function of 3D-bioprinted pancreatic petals with pancreatic islets in the murine model. Glucose, C-peptide concentrations, and histological analyses were performed.

The differentiated epidermis of human skin serves as an essential barrier against environmental insults from physical, chemical, and biological sources. Zinc pyrithione ZnPT is an FDA-approved microbicidal agent used worldwide in clinical antiseptic products, over-the-counter topical antimicrobials, and cosmetic consumer products including antidandruff shampoos. Here we demonstrate for the first time that cultured primary human skin keratinocytes and melanocytes display an exquisite vulnerability to nanomolar concentrations of ZnPT resulting in pronounced induction of heat shock response gene expression and impaired genomic integrity. In keratinocytes and melanocytes, single-cell gel electrophoresis and flow cytometric detection of γ-H2A. X revealed rapid induction of DNA damage in response to ZnPT detectable before general loss of cell viability occurred through caspase-independent pathways. Combined with earlier experimental evidence that documents penetration of ZnPT through mammalian skin, our findings raise the possibility that this topical antimicrobial may target and compromise keratinocytes and melanocytes in intact human skin. The differentiated epidermis of human skin serves as an essential barrier against environmental insults from physical e. Epidermal cells, including keratinocytes, melanocytes, and antigen-presenting Langerhans cells, are key targets of environmental stressors leading to accumulative damage and functional alterations thought to play major roles in skin dysfunction and carcinogenesis Baudouin et al. Much research has focused on the identification and development of drug-like molecules for the prevention of skin damage from environmental insult, particularly photodamage from solar UV radiation Halliday ; Kullavanijaya and Lim ; Wondrak et al. Research from various groups, including our own, has shown that small molecule inducers of the heat shock and Nrf2 nuclear factor-E2-related factor 2 oxidative stress response pathways exert chemopreventive activity with suppression of skin cell photodamage, photooxidative stress, and photocarcinogenesis Dinkova-Kostova et al. Zinc is an important micronutrient and prototype inducer of cytoprotective mechanisms including signaling through Nrf2 and upregulation of metallothionein and heat shock protein expression, all of which have been observed upon exposure to inorganic zinc salts e. In an attempt to explore the potential cytoprotective activity of topical Zn compounds for skin protection against environmental insults, we focused our research efforts on zinc pyrithione ZnPT; CAS number: , a complex between a central zinc atom and the membrane permeable ionophore pyrithione N -hydroxypyridinethione; Barnett et al.

That much we know for sure. But what exactly is Minecraft? Minecraft just may be the most popular video game of all time. With over million copies sold to date, its certainly one for the record books, and its cultural impact is undeniable. The game has spawned countless imitators and dozens of spinoffs. Minecraft skin editors allow you to create your own fantastic characters! In Minecraft, a player skin is just an image file specifically a. What makes Minecraft interesting is that it has no single goal or set of instructions for how to play. Players explore the game, all on their own; whether bashing baddies in Survival Mode, building works of architecture while in Creative Mode, or customizing avatars with a skin editor. Modding with Minecraft means the user has made their own personal change or alteration to the game.
