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.
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.
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.
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.

Coupling of the oxygen-linked interaction energy for inositol hexakisphosphate and bezafibrate binding to human HbA0. (1/606)

The energetics of signal propagation between different functional domains (i.e. the binding sites for O2, inositol hexakisphospate (IHP), and bezafibrate (BZF)) of human HbA0 was analyzed at different heme ligation states and through the use of a stable, partially heme ligated intermediate. Present data allow three main conclusions to be drawn, and namely: (i) IHP and BZF enhance each others binding as the oxygenation proceeds, the coupling free energy going from close to zero in the deoxy state to -3.4 kJ/mol in the oxygenated form; (ii) the simultaneous presence of IHP and BZF stabilizes the hemoglobin T quaternary structure at very low O2 pressures, but as oxygenation proceeds it does not impair the transition toward the R structure, which indeed occurs also under these conditions; (iii) under room air pressure (i.e. pO2 = 150 torr), IHP and BZF together induce the formation of an asymmetric dioxygenated hemoglobin tetramer, whose features appear reminiscent of those suggested for transition state species (i.e. T- and R-like tertiary conformation(s) within a quaternary R-like structure).  (+info)

Altered ligand rebinding kinetics due to distal-side effects in hemoglobin chico (Lysbeta66(E10) --> thr). (2/606)

Hb Chico is an unusual human hemoglobin variant that has lowered oxygen affinity, but unaltered cooperativity and anion sensitivity. Previous studies showed these features to be associated with distal-side heme pocket alterations that confer increased structural rigidity on the molecule and that increase water content in the beta-chain heme pocket. We report here that the extent of nanosecond geminate rebinding of oxygen to the variant and its isolated beta-chains is appreciably decreased. Structural alterations in this variant decrease its oxygen recombination rates without significantly altering rates of migration out of the heme pocket. Data analysis indicates that one or more barriers that impede rebinding of oxygen from docking sites in the heme pocket are increased, with less consequence for CO rebinding. Resonance Raman spectra show no significant alterations in spectral regions sensitive to interactions between the heme iron and the proximal histidine residue, confirming that the functional differences in the variant are due to distal-side heme pocket alterations. These effects are discussed in the context of a schematic representation of heme pocket wells and barriers that could aid the design of novel hemoglobins with altered ligand affinity without loss of the normal allosteric responses that facilitate unloading of oxygen to respiring tissues.  (+info)

Sickle hemoglobin polymer melting in high concentration phosphate buffer. (3/606)

Sickle cell hemoglobin (HbS) prepared in argon-saturated 1.8 M phosphate buffer was rapidly mixed with carbon monoxide (CO)-saturated buffer. The binding of CO to the sickle hemoglobin and the simultaneous melting of the hemoglobin polymers were monitored by transmission spectroscopy (optical absorption and turbidity). Changes in the absorption profile were interpreted as resulting from CO binding to deoxy-HbS while reduced scattering (turbidity) was attributed to melting (depolymerization) of the HbS polymer phase. Analysis of the data provides insight into the mechanism and kinetics of sickle hemoglobin polymer melting. Conversion of normal deoxygenated, adult hemoglobin (HbA) in high concentration phosphate buffer to the HbA-CO adduct was characterized by an average rate of 83 s-1. Under the same conditions, conversion of deoxy-HbS in the polymer phase to the HbS-CO adduct in the solution phase is characterized by an average rate of 5.8 s-1 via an intermediate species that grows in with a 36 s-1 rate. Spectral analysis of the intermediate species suggests that a significant amount of CO may bind to the polymer phase before the polymer melts.  (+info)

Physiological effects of modified hemoglobin as an oxygen-carrying macromolecule. (4/606)

A stabilized hemoglobin as oxygen-carrying macromolecules was developed. It had approximately 90,000 dalton molecular weights and its intravascular half life was 36 hours. Its molecular size was less than 0.1 micron. Its hemoglobin concentration was 6% and P50 value was 24 mmHg. The oxygen carried inside the plasma performs differently than the oxygen carried inside the red cells. Only less than 0.3 ml of oxygen in 100 ml of blood is available inside the plasma while 14-19 ml of oxygen is carried inside the red cells. Thus, less than 5 ml of oxygen is available inside the plasma of the entire body. When a patient develops hypovolemic shock, the red cells are bypassed and are not perfused directly inside the tissues. However, the plasma should reach such hypoxic tissues. Thus, infusion of oxygen-carrying macromolecules in the plasma should be therapeutically effective even if less than 100 ml of stabilized hemoglobin solution were infused under shock conditions. The basic physiology of oxygen-carrying macromolecules is described in detail, which is different from the oxygen carried inside the red cells.  (+info)

Metal complexes as allosteric effectors of human hemoglobin: an NMR study of the interaction of the gadolinium(III) bis(m-boroxyphenylamide)diethylenetriaminepentaacetic acid complex with human oxygenated and deoxygenated hemoglobin. (5/606)

The boronic functionalities on the outer surface of the Gd(III) bis(m-boroxyphenylamide)DTPA complex (Gd(III)L) enable it to bind to fructosamine residues of oxygenated glycated human adult hemoglobin. The formation of the macromolecular adduct can be assessed by NMR spectroscopy via observation of the enhancement of the solvent water proton relaxation rate. Unexpectedly, a strong binding interaction was also observed for the oxygenated unglycated human adult hemoglobin, eventually displaying a much higher relaxation enhancement. From relaxation rate measurements it was found that two Gd(III)L complexes interact with one hemoglobin tetramer (KD = 1.0 x 10(-5) M and 4.6 x 10(-4) M, respectively), whereas no interaction has been observed with monomeric hemoproteins. A markedly higher affinity of the Gd(III)L complex has been observed for oxygenated and aquo-met human adult hemoglobin derivatives with respect to the corresponding deoxy derivative. Upon binding, a net change in the quaternary structure of hemoglobin has been assessed by monitoring the changes in the high-resolution 1H-NMR spectrum of the protein as well as in the Soret absorption band. On the basis of these observations and the 11B NMR results obtained with the diamagnetic La(III)L complex, we suggest that the interaction between the lanthanide complex and deoxygenated, oxygenated, and aquo-met derivatives of human adult hemoglobin takes place at the 2, 3-diphosphoglycerate (DPG) binding site, through the formation of N-->B coordinative bonds at His143beta and His2beta residues of different beta-chains. The stronger binding to the oxygenated form is then responsible for a shift of the allosteric equilibrium toward the high-affinity R-state. Accordingly, Gd(III)L affinity for oxygenated human fetal hemoglobin (lacking His143beta) is significantly lower than that observed for the unglycated human adult tetramer.  (+info)

Fetal hemoglobin (HbF) synthesis in baboons, Papio cynocephalus. Analysis of fetal and adult hemoglobin synthesis during fetal development. (6/606)

Fetal hemoglobin (HbF) and adult hemoglobin (HbA) synthesis was studied in fetal baboons, Papio cynocephalus, to determine the normal pattern of hemoglobin production during fetal development. Fetuses ranging from 53 to 180 days gestation (term gestation 184 days) were used. Erythroid cells were incubated with 3H-L-leucine, and the rates of globin chain synthesis and the distribution of radioactivity into hemoglobin intermediates and completed hemoglobin molecules were determined. Gamma chain synthesis accounted for approximately 97% of the total nonalpha chain synthesis up to 140 days gestation; beta chain synthesis accounted for the remainder. After 140 days gestation, approximately equal quantities of gamma and beta chain were synthesized in the bone marrow. Prior to 140 days gestation, total alpha chain synthesis was 30% greater than total non-alpha chain synthesis, while there was balanced chain synthesis after 140 days gestation. During the period of excess alpha chain synthesis, fetal erythrocytes contained a large pool of alpha-hemoglobin (alpha chain with heme attached) molecules uncombined with beta or gamma chains. In view of the possibility that alpha chains may have a lower affinity for gamma chains than beta chains, excess alpha chain synthesis may be required to maintain low levels of free gamma chains.  (+info)

Kinetic studies on the binding affinity of human hemoglobin for the 4th carbon monoxide molecule, L4. (7/606)

L4, the affinity of hemoglobin for the 4th CO molecule, has been determined for human adult hemoglobin (HbA) as a function of pH and the presence of organic phosphates by measuring the kinetic parameters for the reaction. l'4, the rate of combination of CO with the triliganded molecule, was measured by flash photolysis while l4, the rate of CO dissociation for the ligand-saturated molecule, was measured by ligand replacement. L4 is pH-dependent and affected by 2,3-diphosphoglycerate. Additionally, this pH dependence of the high affinity state is largely eliminated by carboxypeptidase A digestion. L4 for human fetal hemoglobin (HbF) in phosphate buffers was also determined and found to be pH-dependent. These results cannot be reconciled within the framework of the two-state allosteric model. Additional structures in the conformational equilibrium due to either intermediates in the T to R transition or two or more R states must exist.  (+info)

Iron nutritional status in preterm infants fed formulas fortified with iron. (8/606)

AIMS: To prospectively evaluate the iron nutritional status of preterm infants fed either a term (0.5 mg/dl iron) or preterm (0.9 mg/dl) formulas fortified with iron after hospital discharge. METHODS: Healthy low birthweight preterm infants were randomly assigned into three groups at the time of hospital discharge. Group A were fed an iron fortified preterm formula (0.9 mg/dl iron) until 6 months corrected age; group B, a fortified term formula (0.5 mg/l iron) until 6 months corrected age group C, the preterm formula between hospital discharge and term, then the term formula until 6 months corrected age. RESULTS: Seventy eight infants were followed up to 6 months corrected age. Iron intake from formula differed significantly between the groups (A, 1.17 mg/kg/day (SD 0.32) > C, 0. 86 mg/kg/day (SD 0.40) = B, 0.81 mg/kg/day (SD 0.23); p < 0.0001). Haemoglobin concentrations were similar to those of iron sufficient preterm infants of the same postnatal age, and term infants of the same postmenstrual age (after 3 months of age). There were no significant differences in haemoglobin concentration (p = 0.391), plasma ferritin (A vs B, p = 0.322), or in the incidence of iron deficiency (A vs B, p = 0.534). CONCLUSIONS: Iron fortified formulas containing between 0.5 and 0.9 mg/dl iron seem to meet the iron nutritional needs of preterm infants after hospital discharge.  (+info)

Abstract: A simple ketoamine 14C-fructosoglycine with all the fructose carbon atoms labelled was synthesized for studies of possible pathways of the ketoamines metabolism in animal body. The ketoamine bond in the fructosoglycine was not hydrolyzed during incubation with homogenates of rabbit liver, kidney, spleen and testicular tissues within 3 hrs at pH 4.8 and 7.3 as well as after hydrolysis with pancreatine (the enzymatic extract from bovine pancreas) at pH 8.4. 14C-fructosoglycine administered into rabbit circulation was mainly excreted with urine (about 70% of the label) within 8-14 days. The main part of the ketoamine was excreted as fructosoglycine and the lower amount--as glycated dipeptide; some amount of fructosoglycine was hydrolyzed liberating fructose or converted into aldimine which was hydrolyzed with formation of glucose. The ketoamine was metabolized also into non-reducing isosucrose-like glucofructoside, insensitive to acid and enzymatic hydrolysis ...
Hemoglobin: The new conversion factor we use is 0.1551, instead of 0.6205. The new factor gives the conversion of hemoglobin tetramer mass concentration into SI unit (mmol/l). The molecular weight of the hemoglobin tetramer, including the heme groups, is 64,458 g/mol (approximately 4 x 16,000). With a normal hemoglobin concentration of 15 g/dl, the concentration in mmol/l is 2.327. Thus, the conversion factor yields 0.1551 given by 2.327 divided by 15. Note that 4 x 0.1551 is 0.6205, the conversion factor to convert g/dl into the concentration of hemoglobin monomers, not tetramers ...

AU - Sussman, L. G.. PY - 1983/12/1. Y1 - 1983/12/1. N2 - The reactivity of the amino groups of hemoglobin A toward reductive hydroxyethylation with glycolaldehyde in the presence of NaCNBH3 has been investigated. The α-amino groups of the α- and β-chains of hemoglobin A are the most reactive amino groups of the protein for reductive hydroxyethylation; both sites are about equally reactive. Similarly, on reaction of hemoglobin A with glyceraldehyde in the presence of NaCNBH3, the α-amino groups of both the α- and β-chains of the protein undergo selective reductive dihydroxypropylation. Modification of the α-amino groups of hemoglobin A either by reductive hydroxyethylation or reductive dihydroxypropylation apparently lowers the pK(α) of the α-amino groups and results in an early elution of the ...

Obviously, during pregnancy, the entire volume of blood increases significantly, which is one of the primary reasons for the reduction in hemoglobin and the concentration of red blood cells in the body. This process also includes a triggering mechanism for the development of anemia.. A high level of hemoglobin usually suggests that there are too many erythrocytes in the blood. The medical concept is erythrocytosis. This process causes a number of concomitant complications, because it can disrupt blood circulation and lead to its unregulated clotting.. It is very important to have a normal level of hemoglobin just before the pregnancy itself, during the whole period, and naturally after the birth. Regular check of the level of hemoglobin is very important to ensure that the proper level of hemoglobin remains stable.. In the case of anemia, as one of the ways to treat a low level of hemoglobin, the doctor can prescribe iron-containing drugs and special supplements to bring the level to ...

Many animals have as many or more CYP genes than humans do. Reported numbers range from 35 genes in the sponge Amphimedon queenslandica to 235 genes in the cephalochordate Branchiostoma floridae.[30] Mice have genes for 101 CYPs, and sea urchins have even more (perhaps as many as 120 genes).[31] Most CYP enzymes are presumed to have monooxygenase activity, as is the case for most mammalian CYPs that have been investigated (except for, e.g., CYP19 and CYP5). Gene and genome sequencing is far outpacing biochemical characterization of enzymatic function, though many genes with close homology to CYPs with known function have been found, giving clues to their functionality. The classes of CYPs most often investigated in non-human animals are those either involved in development (e.g., retinoic acid or hormone metabolism) or involved in the metabolism of toxic compounds (such as heterocyclic amines or polyaromatic hydrocarbons). Often there are differences in gene regulation or enzyme function of CYPs ...

A peripheral cannula is the most common intravenous access method utilized in both hospitals and pre-hospital services. A peripheral IV line (PVC or PIV) consists of a short catheter (a few centimeters long) inserted through the skin into a peripheral vein (any vein not situated in the chest or abdomen). This is usually in the form of a cannula-over-needle device, in which a flexible plastic cannula comes mounted over a metal trocar. Once the tip of the needle and cannula are introduced into the vein via venipuncture, the cannula is advanced inside the vein over the trocar to the appropriate position and secured, the trocar is then withdrawn and discarded. Blood samples may be drawn directly after the initial IV cannula insertion. Any accessible vein can be used although arm and hand veins are used most commonly, with leg and foot veins used to a much lesser extent. In infants, the scalp veins are sometimes used. The caliber of needles and catheters can be given in Birmingham gauge or French ...

Normal saline (NSS, NS or N/S) is the commonly used phrase for a solution of 0.90% w/v of NaCl, 308 mOsm/L or 9.0 g per litre. Less commonly, this solution is referred to as physiological saline or isotonic saline (because it closely approximates isotonic, that is, physiologically normal, solution); although neither of those names is technically accurate (because normal saline is not exactly like blood serum), they convey the practical effect usually seen: good fluid balance with minimal hypotonicity or hypertonicity. NS is used frequently in intravenous drips (IVs) for people who cannot take fluids orally and have developed or are in danger of developing dehydration or hypovolemia. NS is also used for aseptic purpose. NS is typically the first fluid used when hypovolemia is severe enough to threaten the adequacy of blood circulation, and has long been believed to be the safest fluid to give quickly in large volumes. However, it is now known that rapid infusion of NS can cause metabolic ...

Causes of hyperuricemia that are of mixed type have a dual action, both increasing production and decreasing excretion of uric acid. High intake of alcohol (ethanol), a significant cause of hyperuricemia, has a dual action that is compounded by multiple mechanisms. Ethanol increases production of uric acid by increasing production of lactic acid, hence lactic acidosis. Ethanol also increases the plasma concentrations of hypoxanthine and xanthine via the acceleration of adenine nucleotide degradation, and is a possible weak inhibitor of xanthine dehydrogenase. As a byproduct of its fermentation process, beer additionally contributes purines. Ethanol decreases excretion of uric acid by promoting dehydration and (rarely) clinical ketoacidosis.[5] High dietary intake of fructose contributes significantly to hyperuricemia.[15][16][17] In a large study in the United States, consumption of four or more sugar-sweetened soft drinks per day gave an odds ratio of 1.82 for hyperuricemia.[18] Increased ...
The most commonly known pathogen is Candida albicans, causing roughly 70% of fungemias, followed by Candida glabrata with 10%, Aspergillus with 1% and Saccharomyces as the fourth most common.[citation needed] However, the frequency of infection by C. glabrata, Saccharomyces boulardii, Candida tropicalis, C. krusei and C. parapsilosis is increasing, perhaps because significant use of fluconazole is common or due to increase in antibiotic use.[citation needed]. New emerging pathogen: Candida auris is an emerging multidrug-resistant (MDR) yeast that can cause invasive infections and is associated with high mortality. It was first described in 2009 after being isolated from external ear discharge of a patient in Japan. Since the 2009 report, C. auris infections, specifically fungemia, have been reported from South Korea, India, South Africa, and Kuwait. Although published reports are not available, C. auris has also been identified in Colombia, Venezuela, Pakistan, and the United Kingdom.[3]. ...

PICCs can remain in situ for extended periods of time, from seven days to 4 months [4] up to 12 months although little information is available with respect to viability timeframes. They are used in both the hospital and community settings. PICCs can be used for intravenous delivery of total parenteral nutrition (TPN), chemotherapy, antibiotics or other medications, and can also be used for blood sampling if the lumen is 4 French or larger in size (Arrow and Bard manufacturers guidelines). To maintain patency, PICC management should include regular flushing with normal saline and "locking" with Heparin or normal saline when not in use. The type of locking procedure depends on the type of PICC and bung; Groshong PICCs have a three-way valve at the tip so the use of a heparin lock is not necessary, and there are no clamps on the external length. In comparison, Arrow PICCs have clamps on the exterior line and require a heparin lock. The use of heparin to maintain line patency, though, is ...
Ringer's lactate has an osmolarity of 273 mOsm L−1.[12] The lactate is metabolized into bicarbonate by the liver, which can help correct metabolic acidosis. Ringer's lactate solution alkalinizes via its consumption in the citric acid cycle, the generation of a molecule of carbon dioxide which is then excreted by the lungs. They increase the strong ion difference in solution, leading to proton consumption and an overall alkalinizing effect.[13] The solution is formulated to have concentrations of potassium and calcium that are similar to the ionized concentrations found in normal blood plasma. To maintain electrical neutrality, the solution has a lower level of sodium than that found in blood plasma or normal saline.[4] Generally, the source of the constituent ions is a mixture of sodium chloride (NaCl), sodium lactate (CH3CH(OH)CO2Na), calcium chloride (CaCl2), and potassium chloride (KCl), dissolved into distilled water. Ringer's solution has the same constituents without the sodium lactate, ...
... (RL), also known as sodium lactate solution and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water.[1] It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure.[2] It may also be used to treat metabolic acidosis in cases other than those caused by lactic acidosis and to wash the eye following a chemical burn.[2][3] It is given by injection into a vein or applied to the affected area.[2][3]. Side effects may include allergic reactions, high blood potassium, volume overload, and high blood calcium.[2] It may not be suitable for mixing with certain medications and some recommend against use in the same infusion as a blood transfusion.[4] Ringer's lactate solution has a lower rate of acidosis as compared with normal saline.[1][4] Use is generally safe in pregnancy and breastfeeding.[2] Ringer's lactate solution is in the crystalloid family of medication.[5] ...

The liver has transaminases to synthesize and break down amino acids and to convert energy storage molecules. The concentrations of these transaminases in the serum (the non-cellular portion of blood) are normally low. However, if the liver is damaged, the liver cell (hepatocyte) membrane becomes more permeable and some of the enzymes leak out into the blood circulation. The two transaminases commonly measured are alanine transaminase (ALT) and aspartate transaminase (AST).[1] These levels previously were called serum glutamate-pyruvate transaminase (SGPT) and serum glutamate-oxaloacetate transaminase (SGOT). Elevated levels are sensitive for liver injury, meaning that they are likely to be present if there is injury. However, they may also be elevated in other conditions such as thyroid disorders, celiac disease, and muscle disorders.[4] ALT is usually found only in the liver. AST is most commonly found in the liver, but also in significant amounts in heart (cardiac) and skeletal muscle. ...
Only a limited number of emulsifiers are commonly regarded as safe to use for parenteral administration, of which the most important is lecithin.[medical citation needed] Lecithin can be biodegraded and metabolized, since it is an integral part of biological membranes, making it virtually non-toxic. Other emulsifiers can only be excreted via the kidneys,[citation needed] creating a toxic load. The emulsifier of choice for most fat emulsions used for parenteral nutrition is a highly purified egg lecithin,[36] due to its low toxicity and complete integration with cell membranes. Use of egg-derived emulsifiers is not recommended for people with an egg allergy due to the risk of reaction. In situations where there is no suitable emulsifying agent for a person at risk of developing essential fatty acid deficiency, cooking oils may be spread upon large portions of available skin for supplementation by transdermal absorption. Another type of fat emulsion Omegaven is being used experimentally within the ...
... is the quantitative content of parasites in the blood.[1] It is used as a measurement of parasite load in the organism and an indication of the degree of an active parasitic infection. Systematic measurement of parasitemia is important in many phases of the assessment of disease, such as in diagnosis and in the follow-up of therapy, particularly in the chronic phase, when cure depends on ascertaining a parasitemia of zero. The methods to be used for quantifying parasitemia depends on the parasitic species and its life cycle. For instance, in malaria, the number of blood-stage parasites can be counted using an optical microscope, on a special thick film (for low parasitemias) or thin film blood smear (for high parasitemias). The use of molecular biology techniques, such as PCR has been used increasingly as a tool to measure parasitemia, especially in patients in the chronic phase of disease. In this technique, blood samples are obtained from the patient, and specific DNA of the ...
The precise mechanism by which immunoglobulin therapy suppresses harmful inflammation is likely multifactorial. For example, it has been reported that immunoglobulin therapy can block Fas-mediated cell death.[23] Perhaps a more popular theory is that the immunosuppressive effects of immunoglobulin therapy are mediated through IgG's Fc glycosylation. By binding to receptors on antigen presenting cells, IVIG can increase the expression of the inhibitory Fc receptor, FcgRIIB, and shorten the half-life of auto-reactive antibodies.[24][25][26] The ability of immunoglobulin therapy to suppress pathogenic immune responses by this mechanism is dependent on the presence of a sialylated glycan at position CH2-84.4 of IgG.[24] Specifically, de-sialylated preparations of immunoglobulin lose their therapeutic activity and the anti-inflammatory effects of IVIG can be recapitulated by administration of recombinant sialylated IgG1 Fc.[24] There are several other proposed mechanisms of action and the actual ...
