Diabetes has been recorded in the annals of medical history since ancient Egyptian times when the papyrus of Ebers dated at 1550 BC recommended dietary remedies for those passing abundant urine. Early Sanskrit and Roman literature also included references to 'honeyed urine' and a 'mysterious affection' where thirst was unquenchable and death inevitable (Bloom and Ireland, 1980). Although many researchers have theorized about the cause of the illness, diabetes remains a mysterious and debilitating disease with an unknown etiology (Trucco and Donnan, 1989).
Diabetes mellitus is defined as a chronic disorder which is characterized by an elevated level of glucose in the blood due primarily to inadequate secretion or utilization of insulin (Bloom and Ireland, 1980). In nearly every early text book or treatise on diabetes, diet was stated to be the cornerstone of treatment (Nuttall, 1983). The discovery of insulin by Dr. Frederick Banting and Charles Best in 192 1, however, completely revolutionized the treatment of diabetes and was hailed as one of the greatest medical triumphs of the twentieth century.
Throughout history, many types of labor arrangement have involved the use of coercion the threat or use of force to compel workers to enter into an employment relationship. Slavery was the most common way of organizing labor in a host of ancient civilizations, and was also very prominent in plantation economies throughout the Americas. Other forms of forced labor, such as debt peonage and the state-sanctioned forced recruitment of laborers, also played an important role in the hacienda system that emerged in Latin America during the colonial and post-colonial periods. Episodes of coercion are not only confined to the historical record: they have persisted across both industrialized and developing countries throughout the twentieth century (Andrees and Belser 2009).
• Vermiculite is a sheet silicate mineral that is found as flaky crystals; it is not a fibrous mineral like asbestos. Fibres of vermiculite can be formed by breakage of the flakes or by curling of the edges of the flakes. Such mineral fibres do not constitute asbestos, and fibrous shape does not, by itself, mean that they will behave like asbestos.
• Vermiculite dusts, including these fibrous fragment forms, have demonstrated very few if any health effects, other than those that could be expected from any low toxicity silicate. Unlike asbestos, vermiculite has shown very few ill-effects in experimental testing with animals. Chemical testing suggests that it may not stay long enough in the lung to do serious damage.
