(From Webster, 3d ed; American Heritage Dictionary, 2d college ed)Malaria: A protozoan disease caused in humans by four species of the PLASMODIUM genus: PLASMODIUM FALCIPARUM; PLASMODIUM VIVAX; PLASMODIUM OVALE; and PLASMODIUM MALARIAE; and transmitted by the bite of an infected female mosquito of the genus ANOPHELES. Malaria is endemic in parts of Asia, Africa, Central and South America, Oceania, and certain Caribbean islands. It is characterized by extreme exhaustion associated with paroxysms of high FEVER; SWEATING; shaking CHILLS; and ANEMIA. Malaria in ANIMALS is caused by other species of plasmodia.Osteosclerosis: An abnormal hardening or increased density of bone tissue.Primary Myelofibrosis: A de novo myeloproliferation arising from an abnormal stem cell. It is characterized by the replacement of bone marrow by fibrous tissue, a process that is mediated by CYTOKINES arising from the abnormal clone.Bone Marrow: The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells.

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.

... , Ph.D., M.D., LL.D., Sc.D. (20 February 1860 - 6 February 1945) was an American physiologist. He pioneered the use of heparin as a blood anti-coagulant. William Henry Howell was born in Baltimore, Maryland and graduated from the Baltimore City College high school in 1878. He was educated at Johns Hopkins University, from which he graduated in 1881. He taught at the University of Michigan and at Harvard before becoming professor at Johns Hopkins in 1893. He was dean of the medical school from 1899 to 1911. He was Dean of the School of Hygiene (now Bloomberg School of Public Health) from 1926 to 1931. Dr Howell contributed to the London Journal of Physiology, the Transactions of the Royal Society, the Johns Hopkins Biological Studies, the Journal of Morphology, and the Journal of Experimental Medicine. He was associate editor of the American Journal of Physiology after 1898. He wrote Text-Book of Physiology (1905; fifth edition, 1913). Howell-Jolly body Heparin, and the Howell ...
Almost all vertebrates, including all mammals and humans, have red blood cells. Red blood cells are cells present in blood in order to transport oxygen. The only known vertebrates without red blood cells are the crocodile icefish (family Channichthyidae); they live in very oxygen-rich cold water and transport oxygen freely dissolved in their blood.[9] While they no longer use hemoglobin, remnants of hemoglobin genes can be found in their genome.[10]. Vertebrate red blood cells consist mainly of hemoglobin, a complex metalloprotein containing heme groups whose iron atoms temporarily bind to oxygen molecules (O2) in the lungs or gills and release them throughout the body. Oxygen can easily diffuse through the red blood cell's cell membrane. Hemoglobin in the red blood cells also carries some of the waste product carbon dioxide back from the tissues; most waste carbon dioxide, however, is transported back to the pulmonary capillaries of the lungs as bicarbonate (HCO3−) dissolved in the blood ...

... is a generic term for any type of anemia in which the red blood cells (erythrocytes) are paler than normal. (Hypo- refers to less, and chromic means color.) A normal red blood cell will have an area of pallor in the center of it; it is biconcave disk shaped. In hypochromic cells, this area of central pallor is increased. This decrease in redness is due to a disproportionate reduction of red cell hemoglobin (the pigment that imparts the red color) in proportion to the volume of the cell. Clinically the color can be evaluated by the Mean Corpuscular Hemoglobin (MCH) or Mean Corpuscular Hemoglobin Concentration (MCHC). The MCHC is considered the better parameter of the two as it adjusts for effect the size of the cell has on its color. Hypochromia is clinically defined as below the normal MHC reference range of 27-33 picograms/cell in adults or below the normal MCHC reference range of 33-36 g/dL in adults. Red blood cells will also be small (microcytic), leading to ...
... refers to the propensity of erythrocytes (red blood cells, RBC) to hemolyse (rupture) under stress. It can be thought of as the degree or proportion of hemolysis that occurs when a sample of red blood cells are subjected to stress (typically physical stress, and most commonly osmotic and/or mechanical stress). Depending on the application as well as the kind of fragility involved, the amount of stress applied and/or the significance of the resultant hemolysis may vary. When multiple levels of stress are applied to a given population/sample of cells, a fragility profile can be obtained by measuring the relative or absolute extent of hemolysis existing at each such level, in addition to finding one or more single-number indexes (either measured directly or interpolated) associated with particular respective levels of hemolysis and/or corresponding stress. Fragility testing can be useful to assess cells' ability (or lack thereof) to withstand sustained or repeated stress. ...
... s (RBCs), also called erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O2) to the body tissues-via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues while squeezing through the body's capillaries. The cytoplasm of erythrocytes is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells. The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiological cell function such as deformability and stability while traversing the circulatory system and specifically the capillary network. In humans, mature red blood cells are flexible and oval biconcave disks. They lack a cell nucleus and most organelles, in order to accommodate maximum space for hemoglobin; they can be viewed as sacks of ...
With the exception of mammals, all vertebrate organisms have hemoglobin-containing cells in their blood and all of these red blood cells contain a nucleus. Mammals represent ~5,500 named species out of ~66,000 vertebrate species, and within this ~8% subgroup, red blood cells are known as erythrocytes or RBCs and lack a cell nucleus in mature organisms. In contrast, a nucleated red blood cell (NRBC), also known by several other names, is a mammalian RBC that contains a cell nucleus. NRBCs occur in normal development as progenitor cells in the erythropoietic lineage and in pathological states. Normally, nucleated RBCs are found only in the circulation of fetuses and newborn infants. After infancy, RBCs normally only contain a nucleus during the very early stages of the cell's life, and the nucleus is ejected as a normal part of cellular differentiation before the cell is released into the bloodstream. Thus, if NRBCs are seen on an adult's peripheral blood smear, it suggests ...
The most important function of red blood cells is the transport of oxygen (O2) to the tissues. The hemoglobin absorbs oxygen in the lungs. Then it travels through blood vessels and brings oxygen to all other cells via the heart. The blood cells go through the lungs (to collect oxygen), through the heart (to give all cells oxygen). They go back to the heart to be re-pumped to the lungs (to again collect oxygen), so the blood in your body travels in a double circuit, going through your heart twice before it completes one full circulation of the body. Red blood cells are doughnut-shaped, but without the hole. This shape is called a bi-concave disc. However, hereditary diseases such as sickle-cell disease can cause them to change shapes and stop blood flow in capillaries and veins. Plasma is got from whole blood. To prevent clotting, an anticoagulant (such as citrate) is added to the blood immediately after it is taken. ...

... , also called familial hypotransferrinemia, is an autosomal recessive metabolic disorder in which there is an absence of transferrin, a plasma protein that transports iron through the blood. Atransferrinemia is characterized by anemia and hemosiderosis in the heart and liver. The iron damage to the heart can lead to heart failure. The anemia is typically microcytic and hypochromic (the red blood cells are abnormally small and pale). Atransferrinemia was first described in 1961 and is extremely rare, with only ten documented cases worldwide. The presentation of this disorder entails anemia, arthritis, hepatic anomalies, and recurrent infections are clinical signs of the disease. Iron overload occurs mainly in the liver, heart, pancreas, thyroid, and kidney In terms of genetics of atransferrinemia researchers have identified mutations in the TF gene as a probable cause of this genetic disorder in affected people. Transferrin is a serum transport protein that transports iron to the ...
