Insulin choice

Insulin is the drug treatment of choice for patients with either type 1 or type 2 diabetes during pregnancy glyburide can be used for type 2 diabetes after the eleventh week of gestation. Metformin is also an option. 

With methods for the quantitative analysis of amino acids to hand, the way was now open for the determination of amino acid sequences. Purified bovine insulin was relatively freely available. On the basis of ultracentrifugal analysis (Gutfreund and Ogston), a molecular weight of 12,000 was assumed—as it later emerged, a factor of 2 too high. One of the advantages from the choice of insulin as the protein to sequence was that tryptophan is absent. A 100% recovery of the amino acids could therefore be obtained easily by simple hydrolysis with HC1. In 1948 Tristram reported the complete amino acid composition of the protein. 

Physical properties of the protein structure should be considered in designing strategies to achieve stable formulations because they can often yield clues about which solution environment would be appropriate for stabilization. For example, the insulin molecule is known to self-associate via a nonspecific hydrophobic mechanism66 Stabilizers tested include phenol derivatives, nonionic and ionic surfactants, polypropylene glycol, glycerol, and carbohydrates. The choice of using stabilizers that are amphiphilic in nature to minimize interactions where protein hydrophobic surfaces instigate the instability is founded upon the hydro-phobic effect.19 It has already been mentioned that hydrophobic surfaces prefer... 

Answen Q Proteins with SH2 domains might bind to the insulin receptor substrate-1 (IRS-1) to transmit signals from the insulin receptor, a tyrosine kinase type of receptor. PI-3 kinase is an example of an SH2 domain protein. SH2 domains are not involved in DNA binding (choices A and D). Examples of protein domains that bind DNA include zinc fingers (steroid receptors), leudne zippers (CREB protein), and helix-turn-helbc proteins (homeodomain proteins),... 

Answer C. Insulin increases glucose transport in only two tissues, adipose and muscle. The major site of glucose uptake is muscle, which decreases hyperglycemia. Glucose and ketone transport and metabolism are insulin independent in the brain (choice D). Insulin would slow gluconeogenesis (choice A) and fatty acid release from adipose (choice B). Insulin would inhibit glycogenolysis in the liver (choice E). 

Put the following diagnostic tests in order of relevance for the management of a diabetic patient on insulin therapy, assigning 1 to the lest that should be recommended as first choice and 5 to the lest that should be recommended as a last choice. 

Use of Proteases in Peptide Synthesis. Typically peptides are synthesized the standard solid or liquid phase methodologies (56, 57). However, both of these techniques require harsh chemical reactions which are detrimental to certain amino acids. Furthermore, in practical terms most peptide syntheses are limited to the range of 30 to 50 amino acid residues. Hence, peptide synthesis is still somewhat problematic in many cases. In certain situations, the alternative method of peptide synthesis using proteases is an attractive choice. With this form of synthesis, one can avoid the use of the noxious and hazardous chemicals used in solid or liquid phase peptide synthesis. Since the reactions are enzyme catalyzed, racemization of the peptide bond does not occur. This technique has been used with success in the synthesis and semisynthesis of several important peptides including human insulin (55,59). 

The bioavailability of the insulins is identical when given subcutaneously. The human insulins are slightly less antigenic than pork or beef insulins. Human insulin is the insulin of choice for patients with insulin allergy, insulin resistance, all pregnant patients with diabetes, and any patient who uses insulin intermittently. ... 

Biguanides can be agents of first choice only in Type II diabetic patients with serious overweight as in these patients insulin resistance has a high prevalence. 

Human insulin considered insulin of choice secondary to antigenicity of animal insulins... 

Although b-blockers are considered the treatment of choice for akathisia, low doses of clonazepam, diazepam, or lorazepam may also reduce its severity ( 172, 389, 445, 447, 448, 449 and 450). These BZDs may be a useful alternative when a-blockers are contraindicated (e.g., in patients with asthma, insulin-dependent diabetes meilitus, cardiac conduction abnormalities) or as an adjunct when akathisia persists despite stepwise escalation of these agents ( 177). 

Cardiac dysfunction increases insulin resistance, suggesting that thiazolidinediones, which reduce insulin resistance might be a good choice in patients with diabetes and cardiac dysfunction. However, this case suggests that they can worsen fluid retention, perhaps by vasodilatation (57). 

In the HIV infected population, further evidence suggested that visceral fat accumulation, dyslipidemia, and insulin resistance are closely linked and associated with antiretroviral treatment, most pronounced with the use of protease inhibitors. In contrast, subcutaneous fat wasting is primarily determined by the choice of nucleoside reverse transcriptase inhibitor (NRTI). Switching studies have supported this notion, since substitution of stavudine has been associated with improvement in fat wasting, while switching a protease inhibitor had no beneficial effect in more than 30 clinical trials (142). 

My first concern during Phase 2 was the circulatory cortisol my body was about to produce (which would have normally robbed me of much of my gains from Phase 1). So I wanted to either use chemistry that induced anabolism in spite of catabolism (such as Primobolan Depot or Parabolanjor use chemistry that acted as an anti-catabolic and anabolic (such as Insulin and GH) or both. Another choice that was sometimes taken will be exampled later.. My choice this time was GH/Insulin/T-3 so as to allow my receptors to clear again. 

Many pro s used the Insulin/GH/Thyroid Stack listed in "Cycles " during off phases and gained muscle mass. Some hard-core ideas are not necessarily intelligent choices. However, when utilized properly and intelligently, these cycles increased mass, receptor-site activity, and prepared the body for following AAS protocols... or simply aided in long term mass retention. Also see "Reported Advanced Cycles And Effects" for other techniques and protocols that have been employed. 

Alfa Lipoic Acid Without writing an ad for anybody, let me simply say that Lipoic Acid increases receptor site sensitivity while also mimicking Insulin s actions. Though my choice for micro-nutrient of the year award for maximum creatine transport without an increase in bodyfat synthesis would be 4-hydroxy- Isoleucine. Major potential here ...
