Abstract

We decided to investigate the role of this polymorphism on cardiovascular risk factors and weight loss secondary to a high-protein/low-carbohydrate vs. a standard hypocaloric diet (1,000 kcal/day) over a period of 9 months. A nutritional evaluation was performed at the beginning and at the end of a 9-month period in which subjects received 1 of 2 diets (diet HP: high protein/low carbohydrate vs. S: standard diet). One hundred and four patients (54.7%) had the genotype G1359G and 86 (45.3%) patients had G1359A (77 patients, 25.8%) or A1359A (9 patients, 3.7%) (A-allele-carriers). In subjects with both genotypes, the body mass index, weight, fat mass, waist circumference and systolic blood pressures decreased with both diets. After the diet type HP and in subjects with both genotypes, the glucose, leptin, total cholesterol, LDL-cholesterol, insulin and HOMA-R levels decreased. After diet S and in all subjects, the total cholesterol, LDL cholesterol and leptin levels decreased, too. Our interventional study didn't show a relationship between the rs1049353 CNR-1 polymorphism and body weight response after two different hypocaloric (low carbohydrate/high protein vs. standard) diets over a period of 9 months. However, a low-carbohydr...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases.

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
