Blood proteins, also termed plasma proteins or serum proteins, are proteins present in blood plasma. They serve many different functions, including transport of lipids, hormones, vitamins and minerals in activity and functioning of the immune system. Other blood proteins act as enzymes, complement components, protease inhibitors or kinin precursors. Contrary to popular belief, haemoglobin is not a blood protein, as it is carried within red blood cells, rather than in the blood serum. Serum albumin accounts for 55% of blood proteins, and is a major contributor to maintaining the osmotic pressure of plasma to assist in the transport of lipids and steroid hormones. Globulins make up 38% of blood proteins and transport ions, hormones, and lipids assisting in immune function. Fibrinogen comprises 7% of blood proteins; conversion of fibrinogen to insoluble fibrin is essential for blood clotting. The remainder of the plasma proteins (1%) are regulatory proteins, such as enzymes, proenzymes, and ...
High blood protein (hyperproteinemia) is an increase in the concentration of protein in the bloodstream. High blood protein is not a specific disease or condition in itself, but it might indicate you have a disease.. High blood protein rarely causes signs or symptoms on its own. But sometimes it is uncovered while youre having blood tests done as part of an evaluation for some other problem or symptom.. If your doctor discovers high blood protein during an evaluation, he or she may recommend additional tests to determine if there is an underlying problem.. A total protein test can determine whether you have high blood protein. Other more-specific tests, including serum protein electrophoresis (SPEP), can help determine the exact source, such as liver or bone marrow, as well as the specific protein type involved in your high blood protein levels. Your doctor may order an SPEP if he or she suspects you have a bone marrow disease.. ...

In this article the importance of blood proteins for drug dosing regimes is discussed. A simple mathematical model is presented for estimating recommended drug doses when the concentration of blood proteins is decreased. Practical guidance for drug dosing regimes is discussed and given in the form of a figure. It is demonstrated that correction of drug dosing regimes is needed only for when there is a high level of drug conjugation with blood proteins and a high degree of hypoalbuminaemia. An example of the use of this model is given.

Components of blood have been found to improve health and enhance multiple biological functions in pre-clinical studies of age-related decline. Blood plasma has been particularly important in regulating the complex mechanisms that can cause these effects. The efficacy of plasma is being studied in the clinic for multiple indications. Alkahest has identified a proprietary plasma protein fraction, GRF6019, which shows positive effects on cognitive and motor function in old models. Plasma and plasma protein fractions have been used as human therapies for decades. Some advantages of GRF6019 over plasma may include increased safety, convenience and treatment benefits. Based on the effects observed in laboratory studies, Alkahest is conducting a Phase II study to explore the safety and efficacy of GRF6019 in people with Parkinsons disease (PD)..

We have tabulated the 77 currently known mutations of the familiar human blood protein, serum albumin (ALB). A total of 65 mutations result in bisalbuminemia. Physiological and structural effects of these mutations are included where observed. Most of the changes are benign. The majority of them were detected upon clinical electrophoretic studies, as a result of a point mutation of a charged amino acid residue. Three were discovered by their strong binding of thyroxine or triiodothyronine. A total of 12 of the tabulated mutations result in analbuminemia, defined as a serum albumin concentration of ,1 g/L. These were generally detected upon finding a low albumin concentration in patients with mild edema, and involve either splicing errors negating translation or premature stop codons producing truncated albumin molecules. A total of nine mutations, five of those with analbuminemia and four resulting in variants modified near the C-terminal end, cause frameshifts. Allotypes from three of the point ...
Background: The immense diagnostic potential of human plasma has prompted great interest and effort in cataloging its contents, exemplified by the Human Proteome Organization (HUPO) Plasma Proteome Project (PPP) pilot project. Due to challenges in obtaining a reliable blood plasma protein list, HUPO later re-analysed their own original dataset with a more stringent statistical treatment that resulted in a much reduced list of high confidence (at least 95%) proteins compared with their original findings. In order to facilitate the discovery of novel biomarkers in the future and to realize the full diagnostic potential of blood plasma, we feel that there is still a need for an ultra-high confidence reference list (at least 99% confidence) of blood plasma proteins. Methods: To address the complexity and dynamic protein concentration range of the plasma proteome, we employed a linear ion-trap-Fourier transform (LTQ-FT) and a linear ion trap-Orbitrap (LTQ-Orbitrap) for mass spectrometry (MS) ...

1. Hemoglobins and serum proteins of herring have been analyzed by agar gel electrophoresis (hemoglobins) and combined starch and agar gel electrophoresis (serum proteins). The material comprises twelve samples from the Norwegian coast and the North Sea and one sample from the east coast of Canada, a total of 1,546 specimens. 2. The results of the hemoglobin analyses were in general agreement with the ontogenetic variation described by WILKINS and ILES (1966). 3. Intraspecific variation was noted in the transferrin components. Three common transferrin types were found and assumed to be controlled by two allelomorphic genes. No relation to age or length was found. Presence of additional weak components complicated the type determination. Hemoglobins in the sera as well as prolonged storage made the type determination unreliable. 4. Observed albumin variations could be explained assuming control by two alleles, while observed variations in other serum protein groups were too weak or too diffuse ...

Proteinuria in normal dogs can be produced at will by parenteral injections of dog plasma.. As the plasma injections are continued the plasma protein concentration rises and at some point protein begins to appear in the urine. The level of plasma protein concentration at which proteinuria appears in normal dogs ranges from 9.6 to 10.4 gm. per cent. This may be termed the renal threshold for proteinuria. Repeat experiments in the same dog show threshold levels to be practically identical.. An interval of days (4 to 26 days) has been noted between the start of plasma protein injections and the appearance of the proteinuria. Larger doses of plasma shorten this interval and the critical plasma protein level is attained sooner.. Considerable amounts of protein may appear in the urine-298 gm. protein during a 52 day period in one instance studied-yet the urine clears in 1 to 4 days after cessation of protein injections. Autopsy shows undamaged kidneys.. Maximal levels of plasma protein concentration ...

The amyloid plaques that form between the brains neurons as it ages are toxic and hence cause the cognitive losses associated with Alzheimers.. We have, for the first time, demonstrated that the cytotoxic effects of amyloid beta can be prevented by fibrinogen in a dose-dependent manner. Fibrinogen acts as a shield or antidote against its toxicity, lead scientist of the study Debabrata Dash from Banaras Hindu University (BHU), told IANS on Thursday.. Dash said the toxic effects of amyloid beta on blood platelets as well as on neuronal cells can be significantly reduced by pre-treatment with fibrinogen.. As fibrinogen is already known to bind amyloid beta, it can capture or sequester amyloid beta and prevent the latter from interacting with neuronal cells or platelets, he said.. There is a catch. Fibrinogen does not cross blood-brain barrier (BBB) so this rules out the possibility of the protein gaining entry into brain and capturing the rogue amyloid beta peptides.. But peptides or small ...

Left: Platelets (shown in the left drawing as grey circles) circulate in blood in a resting state and do not interact with blood proteins. Middle: Adsorption of blood proteins to the biomaterial surface is thought to alter their conformation.. Right: Adsorbed proteins are then thought to activate platelets.. Platelet activation leads to changes in their shape and size, secretion of granules and consequent expression of granule markers (CD62P and CD63), activation of the GPIIb/IIIa integrin complex, exposure of phosphatidyl serine (PS) , which catalyzes thrombin production. Thrombin activates fibrin which polymerizes to form the clot. When activated, platelets also secrete over 200 active substances - growth factors and cytokines - with various, sometimes contradictory functions.[4] Understanding how the secretion of these factors is regulated would allow the regenerative potential of the platelets to be harnessed.. ...

Autoimmunity and macrophage recruitment into the central nervous system (CNS) are critical determinants of neuroinflammatory diseases. However, the mechanisms that drive immunological responses targeted to the CNS remain largely unknown. Here we show that fibrinogen, a central blood coagulation protein deposited in the CNS after blood-brain barrier disruption, induces encephalitogenic adaptive immune responses and peripheral macrophage recruitment into the CNS leading to demyelination. Fibrinogen stimulates a unique transcriptional signature in CD11b(+) antigen-presenting cells inducing the recruitment and local CNS activation of myelin antigen-specific Th1 cells. Fibrinogen depletion reduces Th1 cells in themultiple sclerosis model, experimental autoimmune encephalomyelitis. Major histocompatibility complex (MHC) II-dependent antigen presentation, CXCL10- and CCL2-mediated recruitment of T cells and macrophages, respectively, are required for fibrinogen-induced encephalomyelitis. Inhibition of ...
Human Serum Albumin (HSA) is a protein commonly used in vaccines and often administered for serious burn injuries and liver disease and commonly in short supply due to a lack of donors. That's why researchers from Wuhan University have figured out how to grow it-not in people, but in rice.
By using a chemical procedure in which surfactant molecules, a form of wetting agent, are attached to the protein surface, the researchers remove the water by freeze-drying at low temperature to produce a solid powder. When warmed to room temperature, the powder melts to produce a viscous liquid that contains a very high concentration of myoglobin molecules, while the protein structure remains unchanged even though no water is present.. The experiments, carried out by Professor Stephen Mann, Dr Adam Perriman and Alex Brogan and colleagues in the School of Chemistry at the University of Bristol, and reported in the prestigious journal Nature Chemistry, found that the ability of the liquid protein to reversibly bind oxygen remains unchanged, which means that the potency of the oxygen molecules can be varied in response to the pressure applied.. The resulting liquid is a simplified form of artificial blood that might be used as a smart solvent-less fluid of highly concentrated protein for oxygen ...
In NIH-supported study, blood test in symptom-free volunteers links levels of specific protein with beta amyloid deposits. Scientists are seeking ways to detect the earliest stages of Alzheimers disease, since harmful changes may be taking place in the brain years before symptoms appear. Now, researchers report that a blood test detecting a specific protein in blood samples from cognitively normal older people may reflect the levels of beta-amyloid protein in the brain - a hallmark of the disease. Supported in part by the National Institutes of Health, the findings may eventually lead to a blood test that helps predict risk for Alzheimers disease and who may be a good candidate for participating in clinical trials ...

Years before symptoms of Alzheimers disease manifest, the brain starts changing and neurons are slowly degraded. Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research (HIH) and the University Hospital Tuebingen now show that a protein found in the blood can be used to precisely monitor disease progression long before first clinical signs appear. This blood marker offers new possibilities for testing therapies. The study was carried out in cooperation with an international research team and published in the journal Nature Medicine.. The fact that there is still no effective treatment for Alzheimers is partly because current therapies start much too late, says Mathias Jucker, a senior researcher at the DZNEs Tuebingen site and at the HIH. He headed the current study. In order to develop better treatments, scientists therefore need reliable methods to monitor and predict the course of the disease before symptoms such as memory ...

Over ten years, nearly 24,000 children of LSS survivors or controls were screened for electrophoretic variants of 30 blood proteins (Table 1); 10,000 of these children were also tested for enzyme-deficient variants (Table 2). The children were classified into two groups according to the combined parental gonadal dose of each child, either 0.01 Gy or greater (exposed group) or below 0.01 Gy (control group). A total of 1,233 electrophoretic variants and 47 enzyme-deficient variants were detected. Studies of parents showed that most variants were pre-existing and that only six electrophoretic variants and one enzyme-deficient variant originated from new mutations in parental germ cells. In the study of electrophoretic variants, two new mutations were detected in the exposed group and four in controls. The only enzyme-deficient mutant found was in the exposed group ...

Blood accessible biomarkers to assess disease activity and their response to therapies in Juvenile Dermatomyositis (JDM) are urgently needed. This pilot study aims to identify serum protein biomarkers associated with clinical disease activity in untreated JDM and their response to medical therapy. SomaScan® technology screened JDM patients for 1305 proteins at three points: 1) before start of treatment, 2) while on therapy, and 3) after treatment tapering when patients were clinically inactive. To define disease associated biomarkers, SomaScan® data from untreated JDM patients (n = 8) were compared to SomaScan® data from an independent age-matched healthy control group (n = 12). Longitudinal analysis defined treatment responsive proteins at three time points: untreated (7 samples), treated (7 samples), and clinically inactive (6 samples). To confirm the SomaScan® data, a subset of nine candidate proteins (CXCL11, IL-17B, IL-17D, IL-22, CXCL10, MCP-1, ANGPT2, MIF, IL-23) were tested by ELISA after
Analysis of human serum proteins by liquid phase isoelectric focusing and matrix-assisted laser desorption/ionization-mass spectrometry.
Bacterial lipopolysaccharides (endotoxins) show strong biological effects at very low concentrations in human beings and many animals when entering the blood stream. These include affecting structure and function of organs and cells, changing metabolic functions, raising body temperature, triggering the coagulation cascade, modifying hemodynamics and causing septic shock. Because of this toxicity, the removal of even minute amounts is essential for safe parenteral administration of drugs and also for septic shock patients care. The absence of a general method for endotoxin removal from liquid interfaces urgently requires finding new methods and materials to overcome this gap. Nanostructured carbonized plant parts is a promising material that showed good adsorption properties due to its vast pore network and high surface area. The aim of this study was comparative measurement of endotoxin- and blood proteins-related adsorption rate and adsorption capacity for different carboneous materials produced at

alpha-2-HS-glycoprotein (AHSG) also known as fetuin-A is a protein that in humans is encoded by the AHSG gene. Fetuin-A belongs to the fetuin class of plasma binding proteins and is more abundant in fetal than adult blood. Alpha2-HS glycoprotein, a glycoprotein present in the serum, is synthesized by hepatocytes. The AHSG molecule consists of two polypeptide chains, which are both cleaved from a proprotein encoded from a single mRNA. It is involved in several functions, such as endocytosis, brain development and the formation of bone tissue. The protein is commonly present in the cortical plate of the immature cerebral cortex and bone marrow hemopoietic matrix, and it has therefore been postulated that it participates in the development of the tissues. However, its exact significance is still obscure. The choroid plexus is an established extrahepatic expression site. The mature circulating AHSG molecule consists of two polypeptide chains, which are both cleaved from a proprotein encoded from a ...
Bactericidal/permeability-increasing protein (BPI), a cationic protein isolated from human neutrophils, binds lipopolysaccharide (LPS), kills gram-negative bacteria, and neutralizes many of the effects of LPS in vitro and in vivo. We hypothesized that a recombinant 23-kDa NH2-terminal fragment of BPI (BPI23) would reduce acute lung injury in endotoxemic pigs. At -18 h, pigs received an intravenous priming dose of LPS (20 micrograms/kg). Anesthetized ventilated swine were randomized to receive 1) no further treatment (n = 4); 2) LPS (250 micrograms/kg over 50 min) and BPI23 (3-mg/kg bolus and 3 mg/kg over 60 min) (n = 6); or 3) LPS and thaumatin, a cationic protein devoid of LPS neutralizing activity that has a molecular mass and isoelectric point that are similar to that of BPI23 (n = 7). BPI23 treatment significantly ameliorated LPS-induced hypoxemia, functional upregulation of opsonin receptors on circulating phagocytes, and alveolitis but had no effect on the elaboration of tumor necrosis ...
Objectives: The contribution of vascular disease to neurocognitive decline is now widely recognized. Fetuin-A is an abundant plasma protein known to predict vascular disease. Prior studies have shown that fetuin-A levels are lower in patients with Alzheimers disease in direct proportion to the severity of cognitive impairment; however, their association with normal cognitive aging is unknown. We evaluated the association of serum fetuin-A levels with cognitive function in relatively high-functioning, community-dwelling older adults from the Rancho Bernardo Study.. Methods: This is a population-based study of 1382 older adults (median age 75) who had plasma fetuin-A levels and cognitive function evaluated in 1992-96; 855 had repeat cognitive function assessment a median of 4 years later.. Results: Adjusting for age, sex, education, and depression, higher levels of fetuin-A were associated with better baseline performance on the Mini-Mental Status Exam (MMSE) (P=0.012) and a tendency for better ...
The bactericidal/permeability-increasing protein (BPI) gene has been identified as a candidate gene for disease-resistance breeding. We evaluated whether polymorphisms in exons 4 and 10 of the BPI gene are associated with immune indices [interleukin-2 (IL-2), IL-4, IL-6, interferon-b (IFN-b), IL-10, and IL-12]. In this study, we identified one mutation (C522T) in the BPI exon 4 site and two mutations (A1060G and T1151G) in the BPI exon 10 site.
We have examined the interactions of hemoglobin containing liposomes and of liposomes composed of polymerizable phospholipids with blood cells and proteins. All types of liposomes studied bound a variety of serum proteins with IgG being the most abundant component in each case. Polymerized methacrylate liposomes specifically bound a 53 kilodalton protein not bound by other liposome types. None of the liposomes tested provoked platelet aggregation; however, unpolymerized methacrylate liposomes markedly inhibited ADP induced platelet aggregation. Most liposomes tested did not affect clotting of plasma; however, polymerized methacrylate liposomes bound clotting factor V and thus inhibited clotting.*BLOOD PLATELETS

DescriptionCardiopulmonary bypass is a procedure that temporarily substitutes a patients heart and lung functions with an extracorporeal heart-lung machine. This allows surgeons to operate on motionless heart and lungs, while still providing the body with proper blood circulation. However, the heart-lung machine has been shown to activate the bodys systemic inflammatory response, resulting in short- and long- term organ dysfunction, and even death. The severity of this inflammatory response is strongly correlated to the production levels of specific cytokines and complements found in the bloodstream. Current detection methods require taking discrete blood samples during surgery and waiting at least several hours, but typically one to two weeks when including laboratory queue times in hospitals, for results. I propose a microdialysis device that continuously samples the patients blood for biomarkers during surgery. The primary function of this device is to prepare a purified solution, with ...

The findings provide new opportunities to understand the mechanisms controlled by the protein, as well as investigate whether it could be a clinically useful diagnostic marker for early Alzheimers disease. The study was funded in part by the Medical Research Council (MRC), Alzheimers Research UK, Wellcome Trust and the National Institute for Health Research.. The study, led by researchers at the MRC Social, Genetic and Development Psychiatry Centre, analysed blood samples in 55 pairs of identical twins. The twins were taking part in a wider study called TwinsUK and also had taken a memory and thinking test in 1999 and in 2009. The researchers looked for changes in the levels of proteins that might correlate with changes in cognitive function over the ten-year period.. The researchers discovered that the level of a protein called MAPKAPK5 was associated with ten-year change in scores on the memory and thinking test. Those volunteers with lower levels of the protein in their blood tended to have ...

When blood plasma proteins are depleted by bleeding with return of the washed red cells (plasmapheresis) it is possible to bring dogs to a steady state of hypoproteinemia and a constant level of plasma protein production if the diet protein intake is controlled and limited. Such dogs are outwardly normal but have a lowered resistance to infection and to certain intoxications.. When the protein intake of such dogs is completely replaced by the growth mixture (Rose) of crystalline amino acids, plasma protein production is excellent, weight and nitrogen balance are maintained. This growth mixture consists of ten amino acids, threonine, valine, leucine, isoleucine, tryptophane, lysine, phenylalanine, methionine, histidine, arginine, and is as effective as most diet proteins in plasma protein production.. The above amino acid mixture in aqueous solution may be given by vein with equally good plasma protein production and no apparent clinical disturbance even when given rapidly.. Cystine may replace ...
Liver dysfunction of psoriatic patients: low serum total protein and albumin increase hospital stays, Li Yin, Ying Ying Hu, Jing Guo, Jie Tu, Zhi Qiang Yin
Protein electrophoresis is the most frequent measurement of the primary blood proteins: albumin and globulins (alpha1, alpha2, beta, and gamma). Under the influence of an electrical field, at a pH of 8.6, the proteins separated by an electrical charge, molecular size, and shape. Plotted on treated paper, the serum proteins form five homogeneous bands of the relative protein values in percentages. These percentages, when multiplied by the total protein concentration, reflect the absolute value of each protein. High-resolution electrophoresis allows the detection of additional bands or zones. Immunoelectrophoresis may be performed to identify the nature of suspicious bands or to monitor the progress of gammopathies, disturbances in immunoglobulin synthesis. The most rapid form of unknown band identification combines high-resolution electrophoresis with immunoprecipitation. Certain protein electrophoresis band patterns are characteristic of specific disease states. ...
One of the major drawbacks of many current cancer therapies is the lack of selectivity for tumor cells. Given this, a promising approach is the generation of molecularly targeted therapies that are selectively toxic to the tumor, sparing normal cells that have a different molecular phenotype. A potential therapeutic target that we and others have investigated is the DNA damage-induced cell cycle checkpoint, which can be inhibited (at least in cell culture) by pharmacological means, selectively sensitizing cells that have a disrupted p53 pathway.. UCN-01 has been shown to be a potent checkpoint inhibitor in cell culture, but it also has the undesirable properties of avid binding to human serum proteins and inhibition of other, non-checkpoint kinases (14, 15, 16) . Therefore, we have been examining analogues of UCN-01 and related compounds to identify those that sensitize cells to DNA damage by checkpoint inhibition but are more selective and do not bind human serum proteins (17 , 21) . Recent ...
TY - JOUR. T1 - Direct effect of insulin on the synthesis of specific plasma proteins. T2 - Biphasic response of hepatocytes cultured in serum- and hormone-free medium. AU - Liang, T. J.. AU - Grieninger, G.. PY - 1981. Y1 - 1981. N2 - Monolayers of chicken embryo hepatocytes, cultured in chemically defined medium, retain the ability to synthesize a wide spectrum of plasma proteins for several days in the absence of added hormones. Addition of insulin to the medium elicited a biphasic stimulation of plasma protein synthesis: a rapid response of the synthesis of a limited number of plasma proteins (e.g., albumin and α1-globulin M), then, after prolonged exposure to the hormone, the involvement of additional plasma proteins (e.g., fibrinogen and lipoproteins). Synthesis of transferrin and a few other plasma proteins was not affected by the presence of insulin. The degree of stimulation for the most responsive plasma proteins ranged between 2- to 4-fold during the early phase and 10- and even ...
Introduction: The prediction of plasma protein binding (ppb) is of paramount importance in the pharmacokinetics characterization of drugs, as it causes significant changes in volume of distribution, clearance and drug half life. This study utilized Quantitative Structure - Activity Relationships (QSAR) for the prediction of plasma protein binding. Methods: Protein binding values for 794 compounds were collated from literature. The data was partitioned into a training set of 662 compounds and an external validation set of 132 compounds. Physicochemical and molecular descriptors were calculated for each compound using ACD labs/logD, MOE (Chemical Computing Group) and Symyx QSAR software packages. Several data mining tools were employed for the construction of models. These included stepwise regression analysis, Classification and Regression Trees (CART), Boosted trees and Random Forest. Results: Several predictive models were identified; however, one model in particular produced significantly superior
Lowered plasma protein concentration following single injections of gum acacia in the dog is due in some part to dilution, and in greater part to actual decreas
Soon after the introduction of high resolution two-dimensional electrophoresis (2-DE) in 1975 by Klose (16), OFarrell (17), and others, the technique was applied to the plasma proteins by the present authors (18) with the result that the number of resolved species increased to 300 or more. The 2-DE map of human plasma that resulted is recognizably the same as those produced later by many investigators: in contrast to cellular protein patterns, the plasma 2-DE pattern appears basically the same in everyones hands perhaps due to the very high solubility of the proteins involved and the ease with which the distinctive glycosylation trains of specific proteins can be recognized. A more comprehensive database was reported in 1991 in which 727 spots were resolved, of which 376 were identified as 49 different proteins (19). A plasma map using an immobilized pH gradient first dimension separation was presented the following year with 40 protein identifications carried out by microsequencing (20), and ...

In present livestock husbandry with increasing requirements for higher health and welfare issues but also tight economical margins, there is a need for tools allowing the early warning for disease. Ideally, easy to perform tools should be available that warn farmers and veterinarians that animals are infected, preferably before the onset of clinical signs. Regular use of such tools may diminish growth retardations and production losses. However, tests for early diagnosis can only be developed when animal-associated biomarkers exist that differ between uninfected healthy animals and infected, but not yet diseased, animals. The search for such biomarkers can be performed by two different approaches, either focusing on differences in predefined candidate markers, or by comparative fingerprint analysis of all components present in a biological sample.. In human medicine extensive research has been performed aiming at the discovery of early biomarkers for different kinds of disease, including ...

Human serum albumin (HSA) is the most abundant plasma protein in the human body with a plasma concentration of 0.6mM. HSA plays an important role in drug transport and metabolism. Enzymatic activity of HSA on different substrates or drugs has been studied and documented. The structural mechanism of this activity, however, is unknown. In this study, we have determined the crystal structures of HSA-myristate in a complex of aspirin and of salicylic acid, respectively. The crystal structure of HSA-myristate-aspirin illustrates that aspirin transfers acetyl group to Lys199 and is hydrolyzed into salicylic acid by HSA. The hydrolysis product, salicylic acid, remains bound to HSA at a similar location, but it shows a very different orientation when compared with the salicylic acid in the HSA-myristate-salicylic acid ternary complex. These results not only provide the structural evidence of esterase activity of HSA, and demonstrate the conformational plasticity of HSA on drug binding, but also may ...
A total of 32 studies including 27 case-control and 5 cohort studies were included in the current study. Fetuin-A levels in T2D patients were significantly higher than control groups [Hedges g = 1.73, 95% CI (1.25-2.22), P , 0.001], with significant heterogeneity across studies (P , 0.001, I 2 = 98.46%). Findings from meta-analyses of cohort studies showed a statistically significant association between fetuin-A levels and T2D risk [rate ratio = 1.62, 95% CI (1.26-2.08), P , 0.001], with no significant heterogeneity (P = 0.10, I 2 = 46.06%).. ...

A method and system for the extracorporeal treatment of blood to remove fluid from the fluid overloaded patient is disclosed that non-invasively measures osmotic pressure across a filter membrane of a blood filter. The filter is permeable to water and electrolytes, but not to blood protein. The osmotic pressure indicates the protein concentration in the blood. Osmotic pressure is used to detect when hypotension is about to occur in a patient, as a result of excessive blood volume reduction during treatment of the blood. Using the osmotic pressure measurement as a feedback signal, the rate of fluid extraction is automatically controlled to achieve the desired clinical outcome and avoid precipitating a hypotensive crisis in the patient.
The bodys first line of defense, known as the innate immune system, protects against foreign invaders, including tiny microbes, bacteria or viruses. Yet it also poses a major challenge for therapeutic applications that rely on microscopic drug-delivering vehicles, or nanoparticles. These nanoparticles are in the same size range as many pathogens and are quickly detected and destroyed by macrophages, the innate immune systems sentinel cells.. Macrophages rely on proteins in blood serum that stick to foreign objects in the bloodstream; these biological red flags attract macrophages to engulf the intruders. In the past, scientists working on nanoparticles have attempted to circumvent this process by, for example, masking the engineered particles with a compound called polyethylene glycol, or PEG, to create a stealth coat that blocks these blood proteins from sticking to the nanoparticle surface.. A new approach exploits an Achilles heel of the innate immune system. Despite their veracious ...
TY - JOUR. T1 - Novel inhibitors of AKT. T2 - Assessment of a different approach targeting the pleckstrin homology domain. AU - Meuillet, E. J.. PY - 2011/6/1. Y1 - 2011/6/1. N2 - Protein kinase B/AKT plays a central role in cancer. The serine/threonine kinase is over-expressed or constitutively active in many cancers and has been validated as a therapeutic target for cancer treatment. However, targeting the kinase activity has revealed itself to be a challenge due to non-selectivity of the compounds towards other kinases. This review summarizes other approaches scientists have developed to inhibit the activity and function of AKT. They consist of targeting the pleckstrin homology (PH) domain of AKT. Indeed, upon the generation of 3-phosphorylated phosphatidylinositol phosphates (PI3Ps) by PI3-kinase (PI3K), AKT translocates from the cytosol to the plasma membrane and binds to the PI3Ps via its PH domain. Thus, several analogs of PI3Ps (PI Analogs or PIAs), alkylphospholipids (APLs), such as ...
There are no blood values or levels that measure nutritional status. However, there are some blood proteins and enzymes that may alert the physician to changes in the body in response to artificial nutrition. These markers are only one tool that the physician uses in the assessment of the consumers overall health. Although there are a number of markers, I will cover only a few here. Albumin is a protein found in the blood; it is responsible for maintaining proper fluid balance inside the system that circulates the blood in the body (similar action to sodium). It is also involved in carrying various materials and drugs to different body locations. It is made in the liver, and proper nutrition is one mechanism necessary for its production. Historically, low albumin was considered an indication of malnutrition, but we know now that this is not entirely true.. Interpreting blood albumin levels is a complicated and complex process. Low blood albumin levels can be the result of wasting in certain ...

In the first mouse study, when young and old mice were conjoined, allowing blood to flow between the two, the young mice showed a decrease in neurogenesis while the old mice showed an increase. When blood plasma was then taken from old mice and injected into young mice, there was a similar decrease in neurogenesis, and impairments in memory and learning.. Analysis of the concentrations of blood proteins in the conjoined animals revealed the chemokine (a type of cytokine) whose level in the blood showed the biggest change - CCL11, or eotaxin. When this was injected into young mice, they indeed showed a decrease in neurogenesis, and this was reversed once an antibody for the chemokine was injected. Blood levels of CCL11 were found to increase with age in both mice and humans.. The chemokine was a surprise, because to date the only known role of CCL11 is that of attracting immune cells involved in allergy and asthma. It is thought that most likely it doesnt have a direct effect on neurogenesis, ...
Cordell E Logan. Aquagen™ may be one of the greatest discoveries since air. Since 1776, it is estimated that the oxygen in our atmosphere has declined about 11%. Oxygen is needed now more than ever before. Oxygen is a healer and a preventer of disease. Aquagen™ is a stabilized water-oxygen-salt mixture typically used by putting 10-15 drops in pure drinking water as a nutritional supplement.. A lack of oxygen has been assisted with almost all degenerative disease conditions. Lack of oxygen impairs nutrient transport by the red blood cells. Oxygen prevents build up of excess fluid around the cells. Excessive fluid causes oxygen to be pulled in from the blood stream as well as pulling blood proteins into this excess fluid (osmotic pressure gradient changes). This results in less oxygen in the blood and lymphatic congestion. Lack of oxygen contributes to pain. One final stage is when the cells, in a last ditch effort to survive, turns more or less into a plant cell. Plant cells don t use ...
Calcium plays a vital role in the biochemistry of the cell, particularly in signal transduction pathways. The skeleton acts as a major storage site for the element and releases Ca2+ into the bloodstream under controlled conditions. Circulating calcium is either in the free, ionized form or bound to blood proteins such as albumin. The hormone secreted by the parathyroid gland, parathyroid hormone, regulates the resorption of Ca2+ from bone.
That new UCSF paper is yet another example of the intricacies of DNA and gives us a teaching moment on how science can be done in a completely different way. Consider the blood protein hemoglobin found throughout the vertebrate species, illustrated here to show its four protein chains and their many helices. Each of the four chains has about 140 amino acids which are glued together in a long line, and then fold up into a glob. Those 140 amino acids are encoded by the corresponding DNA gene. In the gene, there are three DNA nucleotides for each amino acid. For instance, the figure below shows a short segment of a human and a horse gene, both of which code for a hemoglobin chain. The letters, ACGCT … represent the nucleotides-small molecules that make up the DNA strand. The letters A, C, G and T stand for adenine, cysteine, guanine and thymine, respectfully ...
This test is most often done when your provider suspects you have kidney disease. It may be used as a screening test.. Although small amounts of protein are normally in urine, a routine dipstick test may not detect them. A urine microalbumin test can be performed to detect small amounts of albumin in the urine that may not be detected on dipstick testing. If the kidney is diseased, proteins may be detected on a dipstick test, even if blood protein levels are normal. ...
