One way to avoid this disease is the treatment of other diseases, such as diabetes, thyroid gland diseases, and high blood pressure, in addition to maintaining a healthy lifestyle. This study aimed to find the relationship of thyroid hormone, blood biochemical parameters, and anthropometric measurement with the newly diagnosed diabetic neuropathy in women with hypothyroidism. In total, 90 women (with an age range of 35-55 years) were selected, 45 of whom were diagnosed with diabetic neuropathy and had hypothyroidism, and the other 45 were healthy women recruited as the control group. The following parameters were determined: serum triiodothyronine, thyroxine, thyroid stimulating hormone (TSH), 1,25-Dihydroxyvitamin D3 (DHVD3) activities, anthropometric measurement, fasting blood sugar (FBS), hemoglobin A1C (HbA1C), urea, creatinine, and lipid profile. The results showed a significant increase in the body mass index, blood pressure, TSH, FSB, HbA1C, urea, creatinine, and triglycerides of women with newly diagnosed diabetic neuropathy and hypothyroidism, compared to that in the control group (P≤0.05). A significant decrease was also observed in the high-density lipoprotein cholesterol, DHVD3, total triiodothyronine, and total thyroxine of women with newly diagnosed diabetic neuropathy and hypothyroidism, compared to that in the control group (P≤0.05). There was a correlation between vitamin D3 deficiency (VDD) and thyroid dysfunction in women with the newly diagnosed diabetic neuropathy, which indicated VDD is related to thyroid dysfunction and influences newly diagnosed diabetic neuropathy in women.

The subjects aged ranged (30-50) years and with BMI (25-29) kg/m 2. Serum was used in determination of lipid profile total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), thyroid threonine (T3) and thyroxin (T4), thyroid stimulating hormone (TSH), visfatin and paraoxonase-1 (PON-1). The results showed significant increase in T3, T4, TC, TG, LDL and VLDL in patient group when comparing to control group. While significant decrease was found in TSH and HDL in patient group when comparing to control group. The results also represented significant increase in visfatin levels in patient group comparing to control group. While there are significant reducation in PON-1 levels in patient group comparing to control group. The conclusion could be drown from this study that visfatin and PON-1 effected hyperthyroidism patient's with dyslipidemia All the patients in hyperthyroid group were heterozygotes for Familial Hypercholesterolemia is a disorder that is passed down through families. It causes LDL (bad) cholesterol level to be very high. The condition begins at birth and can cause heart attacks at an early age.

It increases the risk of developing cardiovascular disease and diabetes. (MetS) closely related to the existence weight gain or Obesity and laziness. It increases the serum levels of TNF-α and change the levels of a number of other parameters (e.g., adiponectin, resistin, and PAI-1). TNF-α dose not only appear to cause the production of inflammatory cytokines. It can trigger cell signaling by interacting with TNF-α receptors that can lead to insulin resistance. Usually, the digestive system molders the foods you eat and converts them to glucose. Insulin is an anabolic hormone produced by the pancreas that aids glucose get in your cells. To be utilize, as an energy source .Cells do not respond to insulin normally, and sugar cannot easily enter cells in people with insulin resistance. As outcome, blood glucose rises, until the body produces more insulin in an attempt to lo...

This technology allows an exponential intensification of a minor quantity of DNA molecule several times. Analysis can be straightforward with more DNA available. A thermal heat cycler performs a polymerization chain reaction that involves repeated cycles of heating and cooling the reactant tubes at the desired temperature for each reaction step. A heated deck is positioned on the upper reaction tube to avoid evaporating the reaction mixture (normally volumes range from 15 to 100 l per tube), or an oil layer can be placed on a reaction mixture surface. The amplified DNA fragment is determined based on selecting primers in addition to the starting and end of the DNA fragment. The primers stand for short, artificial DNA stripes, no higher than fifty (typically 18-25bp) nucleotides have been based on a st...
