Reversing new-onset type 1 diabetes with pyramid-like DNA

Usually diagnosed in children, teens and young adults, type 1 diabetes is an autoimmune disease in which the immune system attacks and destroys insulin-secreting β-cells in the pancreas. As a result, people with type 1 diabetes ...

Monitoring glucose levels, no needles required

Noninvasive glucose monitoring devices are not currently commercially available in the United States, so people with diabetes must collect blood samples or use sensors embedded under the skin to measure their blood sugar ...

Blood sugar

Blood sugar concentration, or glucose level, refers to the amount of glucose present in the blood of a human or animal. Normally, in mammals the blood glucose level is maintained at a reference range between about 3.6 and 5.8 mM (mmol/l). It is tightly regulated as a part of metabolic homeostasis.

Mean normal blood glucose levels in humans are about 90 mg/100ml, equivalent to 5mM (mmol/l) (since the molecular weight of glucose, C6H12O6, is about 180 g/mol). The total amount of glucose normally in circulating human blood is therefore about 3.3 to 7g (assuming an ordinary adult blood volume of 5 litres, plausible for an average adult male). Glucose levels rise after meals for an hour or two by a few grams and are usually lowest in the morning, before the first meal of the day. Transported via the bloodstream from the intestines or liver to body cells, Glucose is the primary source of energy for body's cells, fats and oils (ie, lipids) being primarily a compact energy store.

Failure to maintain blood glucose in the normal range leads to conditions of persistently high (hyperglycemia) or low (hypoglycemia) blood sugar. Diabetes mellitus, characterized by persistent hyperglycemia from any of several causes, is the most prominent disease related to failure of blood sugar regulation.
