Microglia
Research has discovered dystrophic (defective development) human microglia. "These cells are characterized by abnormalities in their cytoplasmic structure, such as deramified, atrophic, fragmented or unusually tortuous processes, frequently bearing spheroidal or bulbous swellings." The incidence of dystrophic microglia increases with aging. Microglial degeneration and death have been reported in research on Prion disease, Schizophrenia and Alzheimer's disease, indicating that microglial deterioration might be involved in neurodegenerative diseases. A complication of this theory is the fact that it is difficult to distinguish between "activated" and "dystrophic" microglia in the human brain.
Christopher Hills
Hills and Nakamura had a vision of feeding the world from lakes, seas and backyard aquaculture and in 1975 they authored a book, "Food from Sunlight" which published all their proprietary research as open source for the world to use in the cause against global famine and malnutrition. Their company, Microalgae International, invested in research and technology to find a super food for solving World Hunger. Early research focused on chlorella but its cellular structure was too small to be collected without expensive centrifuges. However, in 1967, while Dr Nakamura was living at Centre House, they discovered that women at Lake Chad were harvesting an algae in baskets to make dihé, a highly nutritious sun-baked biscuit. After studying the lakes of Africa, Hills and Dr Nakamura developed seed culture for a strain of 70% protein algae called spirulina that they had collected from Lake Aranguachi in Ethiopia. Later, in 1981, Dr Hills made an expedition to Lake Chiltu at the invitation of Mr. Wollie Chekal, Minister of Trade for the Ethiopian Revolutionary Government and brought back a new set of spirulina samples to his California laboratory for hybridizing an optimal strain for commercial cultivation.
