DNA Explained DNA Is Material That Governs Inheritance of Eye Color DNA explained DNA is material that governs inheritance of eye color, hair color, stature, bone density and many other human and animal traits. DNA is a long, but narrow string-like object. A one foot long string or strand of DNA is normally packed into a space roughly equal to a cube 1/millionth of an inch on a side. This is possible only because DNA is a very thin string. Our body's cells each contain a complete sample of our DNA. One cell is roughly equal in size to the cube described in the previous paragraph. There are muscle cells, brain cells, liver cells, blood cells, sperm cells and others. Basically, every part of the body is made up of these tiny cells and each contains a sample or complement of DNA identical to that of every other cell within a given person. There are a few exceptions. For example, our red blood cells lack DNA. Blood itself can be typed because of the DNA contained in our white blood cells. Not only does the human body rely on DNA but so do most living things including plants, animals and bacteria.A strand of DNA is made up of tiny building-blocks. There are only four, different basic building-blocks. Scientists usually refer to these using four letters, A, T, G, and C. These four letters are short nicknames for more complicated building-block chemical names, but actually the letters (A,T, G and C) are used much more commonly than the chemical names so the latter will not be mentioned here. Another term for DNA's building blocks is the term, "bases." A, T, G and C are bases. For example, to refer to a particular piece of DNA, we might write: AATTGCCTTTTAAAAA. This is a perfectly acceptable way of describing a piece of DNA. Someone with a machine called a DNA synthesizer could actually synthesize the same piece of DNA from the information AATTGCCTTTTAAAAA alone. The sequence of bases (letters) can code for many properties of the body's cells. The cells can read this code. Some DNA sequences encode important information for the cell. Such DNA is called, not surprisingly, "coding DNA." Our cells also contain much DNA that doesn't encode anything that we know about. If the DNA doesn't encode anything, it is called non-coding DNA or sometimes, "junk DNA."1[1] The DNA code, or genetic code as it is called, is passed through the sperm and egg to the offspring. A single sperm cell contains about three billion bases consisting of A, T, G and C that follow each other in a well defined sequence along the strand of DNA. Each egg cell also contains three billion bases arranged in a well-defined sequence very similar, but not identical to the sperm. Both coding and non-coding DNAs may vary from one individual to another. These DNA variations can be used to identify people or at least distinguish one person from another.

  • Core Laboratory
    Performance of the vast majority of Hematology, Coagulation, Urinalysis, Clinical Chemistry and Toxicology testing procedures is conducted in the CORE LABORATORY - an advanced, highly automated area where whole blood, serum, plasma, urine and other biological fluid specimens are tested for a comprehensive menu of state-of-the-art laboratory procedures. Significant testing procedures for Clinical Chemistry and Toxicology includes panels currently approved by the Centers for Medicare and Medicaid Services: Basic Metabolic Panel; Comprehensive Metabolic Panel; Liver Function Panel; Renal Function Panel; and Electrolyte Panel. Other key tests include the Lipid Profile (Cholesterol, Triglyceride, HDL- Cholesterol and LDL-Cholesterol), major markers of cardiovascular disease and risk [such as Troponin I, Myoglobin and Beta-type natriuretic peptide (commonly referred to as BNAT or BNP)], critical care analytes, beta-HCG, and significant therapeutic drug levels. Urinary toxicology screens for major drugs of abuse (and/or key metabolites) are also performed. The cornerstones of Hematology testing are analyses of the complete blood count (CBC) and the differential (DIFF). These include evaluation of: (1) white blood cell count and differential with percentage and absolute value given for the leukocyte components; (2) circulating erythrocytes by means of hemoglobin, hematocrit, red blood cell count, and red blood cell indices; and (3) measurement of platelet concentration by count and/or estimation. Morphological variations and changes of cellular constituents are reported. Alteration of any aspect of the hemostatic mechanism may cause abnormal bleeding in a wide variety of familial and acquired disorders. These defects may be differentiated by a profile of significant Coagulation laboratory tests that includes PT, PTT, Fibrinogen, FDP, and D-Dimer for monitoring anticoagulant therapy.

    Corporate Medical Policy Genetic Testing for Familial Hypercholesterolemia AHS – M2137 File Name: genetic_testing_for_familial_hypercholesterolemia Origination: 01/01/2019 Last CAP Review: 07/2021 Next CAP Review: 07/2022 Last Review: 07/2021 Description of Procedure or Service Definitions Familial hypercholesterolemia (FH) is a genetic condition that results in premature atherosclerotic cardiovascular disease due to lifelong exposure to elevated low-density lipoprotein cholesterol (LDL-C) levels (Sturm et al., 2018). FH encompasses multiple clinical phenotypes associated with distinct molecular etiologies. The most common is an autosomal dominant disorder caused by mutations in one of three genes, low-density lipoprotein receptor (LDLR), apolipoprotein B-100 (APOB), and proprotein convertase subtilisin-like kexin type 9 (PCSK9) (Ahmad et al., 2016; Goldberg et al., 2011). Rare autosomal recessive disease results from mutation in low-density lipoprotein receptor adaptor protein (LDLRAP) (Garcia et al., 2001).

  • Inflammatory Mechanisms Affecting the Lipid Profile in Patients with Systemic Lupus Erythematosus CECILIA P
    Inflammatory Mechanisms Affecting the Lipid Profile in Patients with Systemic Lupus Erythematosus CECILIA P. CHUNG, ANNETTE OESER, JOSEPH SOLUS, INGRID AVALOS, TEBEB GEBRETSADIK, AYUMI SHINTANI, MacRAE F. LINTON, SERGIO FAZIO, and C. MICHAEL STEIN ABSTRACT. Objective. Increased low density lipoprotein (LDL) cholesterol and triglycerides, and decreased high density lipoprotein (HDL) cholesterol concentrations are associated with adverse cardiovascular risk in the general population. Patients with systemic lupus erythematosus (SLE) have an altered lipid profile characterized by increased triglycerides and decreased HDL cholesterol concentrations. We examined the relationships between lipid concentrations, cytokines, and inflammatory markers in patients with SLE. Methods. Fasting lipid concentrations, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were measured in 110 patients with SLE. Disease activity was quantified by the SLE Disease Activity Index (SLEDAI), and disease damage by the Systemic Lupus International Collaborating Clinics (SLICC) score. Concentrations of circulating tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), and insulin were measured and insulin sensitivity calculated. Results. Lower concentrations of HDL cholesterol were independently associated with higher ESR (p < 0.001), IL-6 (p = 0.02), SLEDAI (p = 0.04), and TNF-α (p = 0.04) after adjustment for age, sex, race, body mass index, insulin sensitivity, and current use of corticosteroids or hydroxychloroquine.

Aims and Objective: To assess lipid profile and its relation with blood glucose levels in patients with MetS. Materials and Methods: This cross-sectional study included 72 male patients with MetS. Anthropometry, lipid profile, blood glucose, and presence of MetS (JIS criteria) were determined. Results: High triglyceride (TG) level (>200 mg/dL, 44.4%) was the most common dyslipidemia followed by low levels of high-density lipoprotein cholesterol (<40 mg/dL, 19.4%). High total cholesterol levels (>240 mg/dL, 13.8%) and high low- density lipoprotein cholesterol levels (>160 mg/dL, 9.7%) were observed. On comparison, no significant differences in lipid levels of MetS patients with normal fasting glucose, impaired fasting glucose, and type 2 diabetes mellitus were observed. Conclusions: Dyslipidemia was frequent in patients with MetS. High TG was the most common lipid abnormality, and a large number of patients had more than one abnormal lipid parameter.

  • Lipid Profile Abnormalities Seen in T2DM Patients in Primary Healthcare in Turkey: a Cross-Sectional Study Aclan Ozder
    Ozder Lipids in Health and Disease 2014, 13:183 http://www.lipidworld.com/content/13/1/183 RESEARCH Open Access Lipid profile abnormalities seen in T2DM patients in primary healthcare in Turkey: a cross-sectional study Aclan Ozder Abstract Background: Diabetes is characterized by chronic hyperglycemia and disturbances of carbohydrate, lipid and protein metabolism. We aimed to research association between serum lipid profile and blood glucose, hypothesizing that early detection and treatment of lipid abnormalities can minimize the risk for atherogenic cardiovascular disorder and cerebrovascular accident in patients with type 2 diabetes mellitus. Methods: Fasting blood glucose (FBG), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride (TG) and glycated haemoglobin (HbA1c) levels were evaluated. A hepatic ultrasound was performed for every diabetic to evaluate hepatosteatosis. The study was done from January 2014 to June 2014 among 132 patients with T2DM who were admitted to outpatient clinic of Family Medicine department in a university hospital. The patients whose taking multi-vitamin supplementation or having hepatic, renal or metabolic bone disorders (including parathyroid related problems) were excluded from the study for the reason that those conditions might affect the carbohydrate and lipid metabolism in diabetes. Test of significance was calculated by unpaired student’s t test between cases and controls. Correlation studies (Pearson’s correlation) were performed between the variables of blood glucose and serum lipid profile. Significance was set at p<0.05. Results: Results of serum lipid profile showed that the mean values for TC, TG, HDL and LDL in female patients were 227.6 ± 57.7 mg/dl, 221.6 ± 101.1 mg/dl, 31.5 ± 6.7 mg/dl and 136.5 ± 43.7 mg/dl, respectively.

  • Association Between Level of Hba1c and Lipid Profile in T2DM Patients Attending Diabetic OPD at BPKIHS
    Baranwal et.al. Association between level of HbA1c and lipid profile Original Article Health Renaissance 2015;13(3): 16-23 Association between level of HbA1c and lipid profile in T2DM patients attending diabetic OPD at BPKIHS JK Baranwal 1, R Maskey 2, S Majhi 3, M Lamsal 1, N Baral 1 Department of Biochemistry 1, Department of Internal Medicine 2, Department of Biochemistry B.P. Koirala Institute of Health Sciences, Xavier University 3 Abstract Hyperglycemia, dyslipidemia and coronary artery disease relate well with each other in type 2 diabetes and it has been proposed that higher prevalence of cardiovascular disease in type 2 diabetes is due to chronic uncontrolled hyperglycemia. Our study aimed to find utility of Hba1c as indicator of dyslipidemia in patients with type 2 diabetes mellitus. We enrolled 168 T2DM patients in our study and collected venous blood samples in both plain and EDTA vials after a fast of minimum 8 hours. Biochemical analysis was done in fully automated analyzer cobas c311. HbA1c was found to have significant positive correlation with total cholesterol, LDL-C, and triglyceride and significant negative correlation with HDL-C and HDL/LDL ratio. The mean value of TC, LDL-C and TG was found to be lower in patients with good glycemic control than those with poor glycemic control. But, mean value of HDL and HDL/LDL ratios were found to be higher in patients with good glycemic control than those with poor glycemic control. These differences were significant at the level of p <0.05. Our study suggests additional use of HbA1c as indicator of dyslipidemia.

  • Cholesterol and Kidney Disease What You Need to Know
    CHOLESTEROL AND KIDNEY DISEASE WHAT YOU NEED TO KNOW WHAT IS CHOLESTEROL? Ã Cholesterol is a type of fat (lipid) found in your blood and other parts of the body. Your body needs small amounts of cholesterol to work normally. Your body can make cholesterol, or get it from certain foods. Ã There are different kinds of cholesterol: Ã LDL cholesterol: Known as the “bad” cholesterol. Too much of it can cause harmful buildup and blockage in your arteries (a type a blood vessel) and causes heart and blood vessel disease. Ã HDL cholesterol: Known as “good” cholesterol. It helps prevent cholesterol from building up in your arteries. Ã Triglyceride: Another type of fat or lipid. Too much of it can also increase your risk for heart and blood vessel disease. Ã A blood test called a complete lipid profile is used to test cholesterol levels. A lipid profile measures for total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. WHAT IS CKD? Ã Chronic kidney disease (CKD) is a loss of kidney function that happens gradually, and which has been present for 3 or more months. In CKD, the kidneys become less able to perform many vital functions, including removing wastes from the body, balancing the body’s fluids, regulating blood pressure, producing red blood cells, and maintaining healthy bones. Ã Urine and blood tests can check for signs of CKD. Albumin-to-creatinine ratio (ACR) is a urine test that checks for high protein in the urine, which is a sign of kidney damage. Glomerular filtration rate (GFR) is a blood test that checks how well the kidneys are filtering.
