Dioxins

Dioxins are organic chemicals that comprise a family of ubiquitous environmental contaminants. Technically speaking, the dioxins of potential toxicological concern are polychlorinated dibenzo-p-dioxins (PCDDs). They are related, both structurally and toxicologically, to polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs). Structures of generic PCDDs, PCDFs, and PCBs are shown in Figure 1. Due to their structural and toxicological similarity and to avoid confusion, all three related groups of chemicals are considered to represent "dioxins" for the purposes of this article. Specific chemicals belonging to this family are referred to as congeners. Collectively, there are more than 200 dioxin-related congeners, and each possesses unique toxicological and chemical properties.

Diabetes 2

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
