Hemoglobins, Abnormal: Hemoglobins characterized by structural alterations within the molecule. The alteration can be either absence, addition or substitution of one or more amino acids in the globin part of the molecule at selected positions in the polypeptide chains.Hemoglobins: The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements.Hemoglobin, Sickle: An abnormal hemoglobin resulting from the substitution of valine for glutamic acid at position 6 of the beta chain of the globin moiety. The heterozygous state results in sickle cell trait, the homozygous in sickle cell anemia.Truncated Hemoglobins: A family of hemoglobin-like proteins found in BACTERIA; PLANTS; and unicellular eukaryotes. Truncated hemoglobins are distantly related to vertebrate hemoglobins and are typically shorter than vertebrate hemoglobins by 20-40 residues.Hemoglobin A: Normal adult human hemoglobin. The globin moiety consists of two alpha and two beta chains.Vitreoscilla: A genus of gram-negative, aerobic or microaerophilic, colorless filaments. It is nonfruiting, motile by gliding, and found in freshwater sediments and cow dung. One species (V. stercoraria) is considered morphologically to be a streptobacillus. That species is strictly aerobic and produces a homodimeric bacterial hemoglobin, especially under oxygen-limited growth conditions. (From Bergey's Manual of Determinative Bacteriology, 9th ed)Hemoglobinopathies: A group of inherited disorders characterized by structural alterations within the hemoglobin molecule.Hemoglobin C: A commonly occurring abnormal hemoglobin in which lysine replaces a glutamic acid residue at the sixth position of the beta chains. It results in reduced plasticity of erythrocytes.Hemoglobin C Disease: A disease characterized by compensated hemolysis with a normal hemoglobin level or a mild to moderate anemia. There may be intermittent abdominal discomfort, splenomegaly, and slight jaundice.Anemia, Sickle Cell: A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.Arcidae: A family of ark shell mollusks, in the class BIVALVIA. They have soft bodies with platelike GILLS enclosed within two shells hinged together.Blood Protein Electrophoresis: Electrophoresis applied to BLOOD PROTEINS.Hemoglobin SC Disease: One of the sickle cell disorders characterized by the presence of both hemoglobin S and hemoglobin C. It is similar to, but less severe than sickle cell anemia.Globins: A superfamily of proteins containing the globin fold which is composed of 6-8 alpha helices arranged in a characterstic HEME enclosing structure.Plesiomonas: A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that occurs in fish and other aquatic animals and in a variety of mammals, including man. Its organisms probably do not belong to the normal intestinal flora of man and can cause diarrhea.Erythrocytes: Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.Oxyhemoglobins: A compound formed by the combination of hemoglobin and oxygen. It is a complex in which the oxygen is bound directly to the iron without causing a change from the ferrous to the ferric state.Thalassemia: A group of hereditary hemolytic anemias in which there is decreased synthesis of one or more hemoglobin polypeptide chains. There are several genetic types with clinical pictures ranging from barely detectable hematologic abnormality to severe and fatal anemia.Diphosphoglyceric AcidsMethemoglobinAntisickling Agents: Agents used to prevent or reverse the pathological events leading to sickling of erythrocytes in sickle cell conditions.Erythrocyte Indices: ERYTHROCYTE size and HEMOGLOBIN content or concentration, usually derived from ERYTHROCYTE COUNT; BLOOD hemoglobin concentration; and HEMATOCRIT. The indices include the mean corpuscular volume (MCV), the mean corpuscular hemoglobin (MCH), and the mean corpuscular hemoglobin concentration (MCHC).Fetal Hemoglobin: The major component of hemoglobin in the fetus. This HEMOGLOBIN has two alpha and two gamma polypeptide subunits in comparison to normal adult hemoglobin, which has two alpha and two beta polypeptide subunits. Fetal hemoglobin concentrations can be elevated (usually above 0.5%) in children and adults affected by LEUKEMIA and several types of ANEMIA.Litsea: A plant genus of the family LAURACEAE. Members contain laurotetanine and other APORPHINES.Electrophoresis, Cellulose Acetate: Electrophoresis in which cellulose acetate is the diffusion medium.Polycythemia: An increase in the total red cell mass of the blood. (Dorland, 27th ed)Electrophoresis, Starch Gel: Electrophoresis in which a starch gel (a mixture of amylose and amylopectin) is used as the diffusion medium.Erythrocytes, Abnormal: Oxygen-carrying RED BLOOD CELLS in mammalian blood that are abnormal in structure or function.Oxygen: An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.Hematocrit: The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.Isoelectric Focusing: Electrophoresis in which a pH gradient is established in a gel medium and proteins migrate until they reach the site (or focus) at which the pH is equal to their isoelectric point.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Erythrocyte Count: The number of RED BLOOD CELLS per unit volume in a sample of venous BLOOD.Electrophoresis: An electrochemical process in which macromolecules or colloidal particles with a net electric charge migrate in a solution under the influence of an electric current.Hemoglobin A, Glycosylated: Minor hemoglobin components of human erythrocytes designated A1a, A1b, and A1c. Hemoglobin A1c is most important since its sugar moiety is glucose covalently bound to the terminal amino acid of the beta chain. Since normal glycohemoglobin concentrations exclude marked blood glucose fluctuations over the preceding three to four weeks, the concentration of glycosylated hemoglobin A is a more reliable index of the blood sugar average over a long period of time.Hemoglobin E: An abnormal hemoglobin that results from the substitution of lysine for glutamic acid at position 26 of the beta chain. It is most frequently observed in southeast Asian populations.Hemoglobin A2: An adult hemoglobin component normally present in hemolysates from human erythrocytes in concentrations of about 3%. The hemoglobin is composed of two alpha chains and two delta chains. The percentage of HbA2 varies in some hematologic disorders, but is about double in beta-thalassemia.Iron: A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.Base Sequence: The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.Plant Proteins: Proteins found in plants (flowers, herbs, shrubs, trees, etc.). The concept does not include proteins found in vegetables for which VEGETABLE PROTEINS is available.Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.Heterozygote: An individual having different alleles at one or more loci regarding a specific character.Chromatography, High Pressure Liquid: Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed.Anemia: A reduction in the number of circulating ERYTHROCYTES or in the quantity of HEMOGLOBIN.CarboxyhemoglobinHemoglobinometry: Measurement of hemoglobin concentration in blood.Blood Substitutes: Substances that are used in place of blood, for example, as an alternative to BLOOD TRANSFUSIONS after blood loss to restore BLOOD VOLUME and oxygen-carrying capacity to the blood circulation, or to perfuse isolated organs.Hemoglobin J: A group of abnormal hemoglobins with similar electrophoretic characteristics. They have faster electrophoretic mobility and different amino acid substitutions in either the alpha or beta chains than normal adult hemoglobin. Some of the variants produce hematologic abnormalities, others result in no clinical disorders.Protein Conformation: The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain).Hemoglobin H: An abnormal hemoglobin composed of four beta chains. It is caused by the reduced synthesis of the alpha chain. This abnormality results in ALPHA-THALASSEMIA.2,3-Diphosphoglycerate: A highly anionic organic phosphate which is present in human red blood cells at about the same molar ratio as hemoglobin. It binds to deoxyhemoglobin but not the oxygenated form, therefore diminishing the oxygen affinity of hemoglobin. This is essential in enabling hemoglobin to unload oxygen in tissue capillaries. It is also an intermediate in the conversion of 3-phosphoglycerate to 2-phosphoglycerate by phosphoglycerate mutase (EC 5.4.2.1). (From Stryer Biochemistry, 4th ed, p160; Enzyme Nomenclature, 1992, p508)Heme: The color-furnishing portion of hemoglobin. It is found free in tissues and as the prosthetic group in many hemeproteins.Erythropoietin: Glycoprotein hormone, secreted chiefly by the KIDNEY in the adult and the LIVER in the FETUS, that acts on erythroid stem cells of the BONE MARROW to stimulate proliferation and differentiation.

... is a variant of Hemoglobin in which a mutation in the alpha globin gene produces an alpha globin chain that is abnormally long. It is the most common nondeletional alpha-thalassemia mutation associated with hemoglobin H disease. The quantity of hemoglobin in the cells is low because the messenger RNA is unstable and some is degraded prior to protein synthesis. Another reason is that the Constant Spring alpha chain protein is itself unstable. The result is a thalassemic phenotype.

... deficiency can be caused either by a decreased amount of hemoglobin molecules, as in anemia, or by decreased ability of each molecule to bind oxygen at the same partial pressure of oxygen. Hemoglobinopathies (genetic defects resulting in abnormal structure of the hemoglobin molecule)[77] may cause both. In any case, hemoglobin deficiency decreases blood oxygen-carrying capacity. Hemoglobin deficiency is, in general, strictly distinguished from hypoxemia, defined as decreased partial pressure of oxygen in blood,[78][79][80][81] although both are causes of hypoxia (insufficient oxygen supply to tissues). Other common causes of low hemoglobin include loss of blood, nutritional deficiency, bone marrow problems, chemotherapy, kidney failure, or abnormal hemoglobin (such as that of sickle-cell disease). The ability of each hemoglobin molecule to carry oxygen is normally modified by altered blood pH or CO2, ...

... is a kind of genetic defect that results in abnormal structure of one of the globin chains of the hemoglobin molecule. Hemoglobinopathies are inherited single-gene disorders; in most cases, they are inherited as autosomal co-dominant traits. Common hemoglobinopathies include sickle-cell disease. It is estimated that 7% of world's population (420 million) are carriers, with 60% of total and 70% pathological being in Africa. Hemoglobinopathies are most common in populations from Africa, the Mediterranean basin and Southeast Asia. Hemoglobinopathies imply structural abnormalities in the globin proteins themselves. Thalassemias, in contrast, usually result in underproduction of normal globin proteins, often through mutations in regulatory genes. The two conditions may overlap, however, since some conditions which cause abnormalities in globin proteins ...
The Hilltop Neighborhood is a historically diverse neighborhood in the Tacoma, Washington Central District. The National Register of Historic Places specifies the geographic area of Hilltop as located within the City of Tacoma and bounded on the east by Tacoma Avenue South, on the north by Division Street, on the west by Sprague Avenue, and on the south by the edge of the bluff, which roughly equates to South 27th Street. Hilltop derives its name from its location on a high bluff overlooking Commencement Bay and the Port of Tacoma. Hilltop is near the historic Tacoma Public Library main branch, Bates Technical College, the Pierce County Courthouse, and the new Pierce County Correctional Facility, all of which are located on Hilltop's east side. It is adjoined by Tacoma's more affluent Stadium District. Sound Transit plans to build a light rail line on Martin Luther King Jr. Way, between Division Avenue and South 19th Street, by 2022, connecting to the existing Tacoma Link in Downtown Tacoma.

Hemoglobin subunit epsilon is a protein that in humans is encoded by the HBE1 gene. The epsilon globin gene (HBE) is normally expressed in the embryonic yolk sac: two epsilon chains together with two zeta chains (an alpha-like globin) constitute the embryonic hemoglobin Hb Gower I; two epsilon chains together with two alpha chains form the embryonic Hb Gower II. Both of these embryonic hemoglobins are normally supplanted by fetal, and later, adult hemoglobin. The five beta-like globin genes are found within a 45 kb cluster on chromosome 11 in the following order: 5' - epsilon - gamma-G - gamma-A - delta - beta - 3'.

In heterozygote advantage, or heterotic balancing selection, an individual who is heterozygous at a particular gene locus has a greater fitness than a homozygous individual. Polymorphisms maintained by this mechanism are balanced polymorphisms.[5]. A well-studied case is that of sickle cell anemia in humans, a hereditary disease that damages red blood cells. Sickle cell anemia is caused by the inheritance of a variant hemoglobin gene (HgbS) from both parents. In these individuals, hemoglobin in red blood cells is extremely sensitive to oxygen deprivation, and this causes shorter life expectancy.. A person who inherits the sickle cell gene from one parent, and a normal hemoglobin gene (HgbA) from the other, has a normal life expectancy. The heterozygote is resistant to the malarial parasite which kills a large number of people each year. The heterozygote frequency is kept high because of the fierce selection ...

Gabriel John Utterson and his cousin Richard Enfield reach the door of a large house on their weekly walk. Enfield tells Utterson that months ago he saw a sinister-looking man named Edward Hyde trample a young girl after accidentally bumping into her. Enfield forced Hyde to pay £100 to avoid a scandal. Hyde brought them to this door and provided a cheque signed by a reputable gentleman (later revealed to be Doctor Henry Jekyll, a friend and client of Utterson). Utterson is disturbed because Jekyll recently changed his will to make Hyde the sole beneficiary. Utterson fears that Hyde is blackmailing Jekyll. When Utterson tries to discuss Hyde with Jekyll, Jekyll turns pale and asks that Hyde be left alone. One night in October, a servant sees Hyde beat Sir Danvers Carew to death, another of Utterson's clients. The police contact Utterson, who leads officers to Hyde's apartment. Hyde has vanished, but they find half of a broken cane (the other half having been left at the crime scene). Utterson ...

  • Hemoglobinopathies occur when changes (mutations) in the genes that code for the globin chains cause alterations in the proteins. (labcorp.com)
  • When an A1C result is inconsistent with a patient's clinical situation, conditions that affect red blood cell lifespan and hemoglobinopathies must be considered as possible causes 1 , 4 because normative values for A1C are based on individuals with a normal hematological profile. (diabetesjournals.org)
  • 9 Because of its prevalence and wide ethnic variation, testing for sickle cell and other selected hemoglobinopathies is routinely performed as part of newborn screening programs in the United States. (diabetesjournals.org)
  • 1 ) altering the normal process of glycation of HbA to A1C, 2 ) causing an abnormal peak on chromatography, making estimation of A1C unreliable, and 3 ) making the red blood cell more prone to hemolysis, thereby decreasing the time for glycosylation to occur and producing a falsely low A1C result.
