Aluminum-induced "mixed" cell death in mice cerebral tissue and potential intervention.

The brain is one of organs vulnerable to aluminum insult. Aluminum toxicity is involved in neurobehavioral deficit, neuronal cell dysfunction, and death. The aim of this study are as follows: (1) to evaluate the repairing efficiency of Necrostatin-1 (Nec-1), a cell death inhibitor, and Z-VAD-FMK, a pan-caspase inhibitor, on Al-induced neurobehavioral deficit and neuronal cell death, in order to evidence the cell death inducing ability of aluminum, and (2) to primarily explore the possibility of treating neuronal cell loss-related disease, such as Alzheimer's disease, with Nec-1 and Z-VAD in Al-induced dementia animal model.

Expression of tissue inhibitor of metalloproteinase-4 in normal human corneal cells and experimental corneal neovascularization.

Purpose: To study the expression of TIMP-4 in cultured corneal cells and in corneal neovascularization.

Methods: Human limbo-corneal epithelial cells, fibroblasts, and endothelial cells were cultured in serum-free, PMA- or basic fibroblast growth factor (bFGF)-treated condition. Neovascularization in rat cornea was induced by suturing.
