Short-acting regular insulin
Native or regular insulin molecules associate as hexamers in aqueous solution at a neutral pH and ¬¬¬___ aggregation slows absorption following subcutaneous injection. Regular insulin should be injected 30-45 minutes before a meal. Regular insulin also may be given intravenously or intramuscularly.
Short-acting insulin analogs
The development of short-acting insulin analogs that retain a monomeric or dimeric configuration is a major advance in insulin therapy. These analogs are absorbed more rapidly from subcutaneous sites than regular insulin. Consequently, there is a more rapid inscrease in plasma insulin concentration and an earlier response. Insulin analogs should be injected ≤15 minutes before a meal.
Insulin lispro (HUMALOG) is identical to human insulin except at positions B28 and B29, where the sequence of

Neutral protamine hagedorn (NPH; insulin isophane) is a suspension of native insulin complexed with zinc and protamine in a phosphate buffer. This produces a cloudy or whitish solution in contrast to the clear appearance of other insulin solutions. Because of this formulation, the insulin dissolves more gradually when injected subcutaneously and thus its duration of action is prolonged. NPH insulin is usually given either once a day (at bedtime) or twice a day in combination with short-acting insulin. In patients with type 2 diabetes, long-acting insulin is often given at bedtime to help normalise fasting blood glucose. It should be noted that the use of long-acting basal insulin alone will not control postprandial glucose elevation in insulin-deficient type 1 or 2 diabetes.
Insulin glargine (LANTUS) is a long-acting analog of human insulin that is produced following two alterations of human insulin. Two arginine residues are added to the C terminus of the B chain, and an asparagine molecule in position 21 on the A chain is replaced with glycine. Insulin glargine is a clear solution with a pH of
... is a technique that monitors the glucose level without the use of needles. Another type of therapy is the artificial pancreas. It combines glucose sensing and insulin delivery through a closed loop system. Mimicking the human pancreas, this therapy would register the blood glucose levels and in response deliver the right amount of insulin.

Frederick Banting, with the help of Charles Herbert Best, J.R.R. Macleod and James Bertram Collip, was able to isolate insulin from animals and treat patients suffering from diabetes, using injections of the insulin. The insulin injections succeeded in treating diabetes.
In 1994, Zhang et al discovered the Ob gene and the hormone leptin1. This brought about the idea that obesity might have genetic-related factors and may not simply involve lack of self-control and overeating in the individual. The Ob gene regulates the amount of body fat storage in the body2. When the Ob gene signals, the hormone leptin is secreted from adipocytes1 and it travels to the hypothalamus in the brain2. This signals the hypothalamus to induce a feeling of satiety2. In other words, leptin secretion causes the stomach to feel full and ceases the necessity for eating. Once this discovery was made, the idea of obesity treatment came into play. If a hormone with satiety-inducing effects can be utilized for treatment then obesity may possibly become a null issue. Unfortunately this is an issue that still stands today – 20 years after the discovery of leptin.
Insulin: a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). Before insulin Diabetes mellitus was a chronic disease that affected thousands of people in Canada and beyond. In the first half of the 20th century, medical professionals understood that diabetes mellitus involved the body’s inability to metabolize food, especially carbohydrates. “Insuline” was already in development as many medical professionals like Joseph Freiherr and Oscar Minkowski, isolated its properties before Banting had his ideas. As well Ancient Greek
Either the A or B chain of insulin is then extracted from the b-galactose and purified. The two chains are then mixed. A chemical reaction forms the disulfide cross bridges connecting the two chains and resulting in Humilin.
...adjusted at any time if needed. Needles are never fun and the thought of having to be stuck by one every day may be horrifying to some, but have no fear there is but one more option. A patient may opt out of injections, if ok by doctor, and take the oral medications. The oral medication, that is prescribed, helps stimulate the pancreas so that it will produce and release insulin on its own. Although, there are many different options to manage diabetes the use of any of these techniques must first be okayed by the patient’s primary doctor.
II. The American Diabetes association, containing health care professionals and staff members from all over the world, wrote an article published in September 14, 2014 describing two conditions when the body’s respond to insulin is crucial.
Type 1 diabetes, is an incurable but treatable disease which can occur at any age but is mostly found in children due to the high levels of glucose in the blood (Eckman 2011). Juvenile diabetes affects about 1 in every 400-600 children and more than 13,000 are diagnosed yearly (Couch 2008). Type 1 Diabetes means your blood glucose, or blood sugar, is too high. With Type 1 diabetes, your pancreas does not make insulin. Insulin is a hormone, which helps glucose gets into your cells to provide energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, gums and teeth (American Diabetes Association). Previous research has suggested proper insulin management, a balanced diet and exercise will help maintain glycemic control and lessen the chance of complications (Couch 2008).
Common treatment for Type I is insulin dosing. The goal of this treatment therapy is to maintain near-normal blood glucose values. Insulin is usually given two or more times a day by injection or is delivered via insulin pump** as needed. . (Wong, Hockenberry, Wilson, 2015) Child receives Novolog** via her insulin pump as
Learning how to inject yourself with insulin, is also a difficult task. It is a struggle dealing with this terrible disease, however, through maintaining of a healthy, and nutritious diet, taking all medication as prescribed, and exercising as needed, may someday reverse the conditions of this disease. Being disciplined is the key.
Within 30 minutes of teaching lesson, the patient will be able to injection insulin properly. The patient will be able to perform self-monitoring of blood glucose using a blood gl...
According to DNA Learning Center, synthetic human insulin was the first precious molecule of the biotech industries and the direct result of recombinant DNA technology. In this process, recombinant DNA technology is used to modify Escherichia coli bacteria to produce artificial human insulin. Basically, insulin is the hormone that used in metabolism of carbohydrate and produced in the pancreas. People with lacks of insulin can result in diabetes because the carbohydrates cannot metabolize into smaller molecules. But, with the achievement of the production artificial insulin, patient with diabetes now can be
