    Full Text Available Especially viral hepatitis viruses and human immunodeficiency virus(HIV which were transmitted by the transfusion of blood and blood products have been an important public health problem for a long time on the world. Transfusion of blood and blood products is an ideal and an easiest and a simplest route for transmission of infectious diseases. It is known that many infectious agents, either bacterial, viral, parasitic and fungal agents may be transmitted by the transfusion of blood and blood products. In present study, we reviewed infection diseases that transmitted by the transfusion of blood and blood products.Additionally, we were aimed to emphasize a rare but a very important complication of transfusion of blood and blood products.

    It is sometimes necessary for the practitioner to transfuse the ruminant with whole blood or plasma. These techniques are often difficult to perform in practice, are time-consuming, expensive, and stressful to the animal. Acute loss of 20% to 25% of the blood volume will result in marked clinical signs of anemia, including tachycardia and maniacal behavior. The PCV is only a useful tool with which to monitor acute blood loss after intravascular equilibration with other fluid compartments has occurred. An acutely developing PCV of 15% or less may require transfusion. Chronic anemia with PCV of 7% to 12% can be tolerated without transfusion if the animal is not stressed and no further decline in erythrocyte mass occurs. Seventy-five percent of transfused bovine erythrocytes are destroyed within 48 hours of transfusion. A transfusion rate of 10 to 20 mL/kg recipient weight is necessary to result in any appreciable increase in PCV. A nonpregnant donor can contribute 10 to 15 mL of blood/kg body weight at 2- to 4-week intervals. Sodium citrate is an effective anticoagulant, but acid citrate dextrose should be used if blood is to be stored for more than a few hours. Blood should not be stored more than 2 weeks prior to administration. Heparin is an unsuitable anticoagulant because the quantity of heparin required for clot-free blood collection will lead to coagulation defects in the recipient. Blood cross-matching is only rarely performed in the ruminant. In field situations, it is advisable to inject 200 mL of donor blood into the adult recipient and wait 10 minutes. If no reaction occurs, the rest of the blood can probably be safely administered as long as volume overload problems do not develop. Adverse reactions are most commonly seen in very young animals or pregnant cattle. Signs of blood or plasma transfusion reaction include hiccoughing, tachycardia, tachypnea, sweating, muscle tremors, pruritus, salivation, cough, dyspnea, fever, lacrimation, hematuria

  2. Transfusions of blood and blood products and viral infections

    Directory of Open Access Journals (Sweden)

    2002-06-01

    Full Text Available Transfusions of blood and blood products are commonly used in medicine, but being biological materials they carry a risk of transmitting infections--viral, bacterial, parasitic, as well as prions. Laboratory tests used for screening of donated blood for viral infections at present cannot detect all infectious units. Criteria for selection of blood donors therefore must be very strict, while methods of inactivation of viruses and laboratory assays for detection of their presence must be improved. Indications for blood transfusion should be restricted.

    2015-08-01

    In order to answer to its aim of standardised self-sufficiency, the Établissement français du sang (main French national platform for blood donation) needs to know well the donors, what moves them, what motivates them, and the meaning that they give to their action. This knowledge allows the EFS to better understand the different sensitivities among donors, and therefore to improve the strategy regarding loyalty or/and newcomers. In this paper we follow, without attempting to be fully exhaustive, the evolution of the research regarding blood donation. The aim is to highlight the role played by social and historical representations regarding donation in general. In a given community, its norms, and its values influence both the image of donors as well as the meaning attached to the act itself of donation. Moreover, these norms have also influenced the way that research has tried to analyse this topic. The initial studies conducted in this field tried generally to understand the meaning and the symbolism attached to the act of blood donation. Later on, researchers started to focus on the assessment of notions such as generosity, and then solidarity. Nowadays, research is more focused on describing the population that gives blood. They are more scrutinised through their socio-demographic traits (who they are) than through the specific study of how they donate, the reasons behind the decision to act and the notion of satisfaction.

    Full Text Available OBJECTIVE: The purpose of this study was to determine the rate and causes of wastage of blood and blood products (packed red cells, plasma, platelets, and cryoprecipitate in Qazvin hospitals. METHODS: The study was conducted in all hospitals in Qazvin, including 5 teaching hospitals, 2 social welfare hospitals, 3 private hospitals, 1 charity hospital, and 1 military hospital. This descriptive study was based on available data from hospital blood banks in the province of Qazvin. The research instrument was a 2-part questionnaire. The first part was related to demographic characteristics of hospitals and the second part elicited information about blood and blood component wastage. The collected data were then analyzed using descriptive statistic methods and SPSS 11.5. RESULTS: Blood wastage may occur for a number of reasons, including time expiry, wasted imports, blood medically or surgically ordered but not used, stock time expired, hemolysis, or miscellaneous reasons. Data indicated that approximately 77.9% of wasted pack cell units were wasted for the reason of time expiry. Pack cell wastage in hospitals is reported to range from 1.93% to 30.7%. Wastage at all hospitals averaged 9.8% among 30.913 issued blood products. Overall blood and blood product (packed red cells, plasma, platelets, and cryoprecipitate wastage was 3048 units and average total wastage per participant hospital for all blood groups was 254 units per year. CONCLUSION: Blood transfusion is an essential part of patient care. The blood transfusion system has made significant advancements in areas such as donor management, storage of blood, cross-matching, rational use of blood, and distribution. In order to improve the standards of blood banks and the blood transfusion services in Iran, comprehensive standards have been formulated to ensure better quality control in collection, storage, testing, and distribution of blood and its components for the identified major factors

    2012-01-01

    SAD_BaSe is a blood bank data analysis software, created to assist in the management of blood donations and the blood production chain in blood establishments. In particular, the system keeps track of several collection and production indicators, enables the definition of collection and production strategies, and the measurement of quality indicators required by the Quality Management System regulating the general operation of blood establishments. This paper describes the general scenario of blood establishments and its main requirements in terms of data management and analysis. It presents the architecture of SAD_BaSe and identifies its main contributions. Specifically, it brings forward the generation of customized reports driven by decision making needs and the use of data mining techniques in the analysis of donor suspensions and donation discards.

  6. Federalism and technological change in blood products.

    Science.gov (United States)

    Taylor, Mark Zachary

    2009-12-01

    Recent research has shown how federalism affects health care finance, health care reform, and health policy innovation. The purpose of this article is to extend this research program to study the linkages between federalism and technological change. It does so using comparative case studies spanning five countries to examine innovation and diffusion of two blood technologies-enzyme-linked immunosorbent assays (ELISA blood tests) and heat treatment-in response to the threat to the blood supply posed by HIV during the 1980s. Prior research has produced three contradictory models of the federalism-innovation relationship. This article attempts to resolve these contradictions, posits new hypotheses, and highlights sources of omitted variable bias that have important implications for understanding technological change. The case studies show that overall decentralization, rather than federalism alone, aids technological progress by allowing its supporters to "venue shop" around political resistance. Decentralization also makes the state less vulnerable to capture by status-quo interest groups. Moreover, political decentralization may have a positive effect on technological diffusion, but a far weaker effect on innovation. Thus, prior research that conflates these two effects should be revisited. PMID:20018985

    This study examined the prevalence of three human herpesviruses (HHV), namely HHV-4 (Epstein-Barr virus/EBV), HHV-6b and HHV-7 in leucoreduced blood products obtained from the Sainte-Justine Hospital blood bank. A total of 100 specimens, including 34 red blood cell concentrates, 33 platelet bags and 33 plasma units, were collected and screened by a sensitive PCR assay using virus-specific primers. Positive units were then retested by quantitative PCR. Of the 100 specimens, one platelet unit tested positive for EBV. PMID:26383177

  13. Prions: Clinical significance, epidemiology and possibilities of transmission by blood and blood products

    Full Text Available Introduction Prions play a leading role in development of transmissible spongiform encephalopathies (TSE. These infectious particles, smaller than viruses and viroids, consist of special kind of proteins and don't contain nucleic acids. Due to that, they are named defective viruses. Biochemical characteristics Prion protein determined as PrPcs was isolated in infective material of all known prion diseases. This represents an abnormal conformer of PrPc prion protein, normally synthetized in all cells, predominantly in neurons of vertebrates. Pathogenesis of TSE Transmissible spongiform encephalopathies are neurodegenarative diseases whose pathogenesis includes modification of secondary structure of normal glycoprotein - prion protein. In human peripheral blood, PrP are expressed in T and B lymphocytes, NK cells, monocytes, dendritic cells, platelets and plasma. Epidemiological studies Investigations of transmission of prions to experimental animals showed that lymphoid tissues are infectious in the earliest phase of the disease. Experimental transmission of sporadic Creutzfeldt-Jakob disease (CJD by intracerebral inoculation of experimental animals with whole blood buffy coat, platelet concentrates, plasma, early Cohn fractions and albumin preparations, has been reported. A small number of clinical studies reported transmission of CJD by human blood, urine and lymphoid tissues and the role of B lymphocytes in neuroinvasion and transmission of prions. Conclusion Thus, importance of prion diseases in blood transfusion is obvious. Iatrogenic transmission of prion diseases by blood and blood products, can't be neglected. Moreover, it is necessary to find markers in prion diseases as well as new technologies and methodologies in blood transfusion practice to minimize the theoretical risk of transmission of prion diseases by blood and blood products.

    Full Text Available Background: Massive transfusion protocols (MTPs are increasingly used in the transfusion practice and are developed to provide the standardized and early delivery of blood products and procoagulant agents and to supply the transfusion of blood products in a well-balanced ratio. Aim: The aim of this study was to investigate the effect of a hospital-wide introduction of an MTP on blood product ratio and a waste of blood products. Materials and Methods: Retrospective analysis was performed to compare the transfusion practice in massive bleeding patients before and after the introduction of an MTP and between the use of an MTP and transfusion off-protocol. Massive bleeding was defined as an administration of ≥5 units of red blood cells (RBCs within 12 h. Results: Of 547 massively transfused patients, 192 patients were included in the pre-MTP period and 355 patients in the MTP period. The ratio of RBC to fresh frozen plasma (FFP and the platelets transfused shifted significantly toward 1:1:1 in the MTP period (P = 0.012. This was mainly caused by a shift in RBC: FFP ratio (P = 0.014. An increase in the waste of blood products was observed, most notably FFPs (P = 0.026. Extending the storage time after thawing reduced the waste of FFPs from 11% to 4%. Conclusion: Hospital-wide introduction of an MTP is an adequate way to achieve a well-balanced transfusion ratio of 1:1:1. This comes at the cost of an increase in the waste of FFPs, which is lowered after extending the duration of storage time after thawing.

    A 53-year-old white man had fever, malaise, and dyspnea on exertion. His chest roentgenogram was normal, but pulmonary function tests showed impaired diffusion capacity and a gallium scan showed marked uptake in the lungs. Results of an open-lung biopsy documented Pneumocystis carinii pneumonia. Immunologic test results were consistent with the acquired immunodeficiency syndrome. The patient denied having homosexual contact or using intravenous drugs. Twenty-nine months before the diagnosis of pneumocystis pneumonia was made, the patient had had 16 transfusions of whole blood, platelets, and fresh-frozen plasma during coronary artery bypass surgery at another medical center. This patient is not a member of any currently recognized high-risk group and is believed to have contracted the acquired immunodeficiency syndrome from blood and blood-product transfusions.

  18. Irradiation of blood products - current status, problems and requirements

    International Nuclear Information System (INIS)

    The irradiation of blood products prior to transfusion is a routine practice in modern medicine. The annihilation of immunocompetent cells in bio products prevents the development of a number of acute and late reactions and consequences. Bone-marrow transplantation is a therapy of especially high risk. The main problems ensue from the toxicity of the preceding treatment, the durable hemopoietic and immune deficiency, the rejection immune reactions and the ability of survival of the malignant cell populations. The irradiation of blood products is of primary importance for the protection from the related with transfusions reaction of the transplant against the host, the so-called Graft-versus-Host-Disease. The optimal irradiation procedure at the present stage of knowledge is considered to be to apply a dose of 30 Gy and a minimal dose of 25 Gy. A number of dosimetric investigations prove the considerable deviations from the nominal dose, as well as other technical problems occur, obviously due to imperfection of the used instrumentation. The construction, principles of operation and a number of technical problems leading to inhomogeneous dose distribution, most often verified by the use of phantoms, are considered in detail for the applied irradiators. The necessity of using standard procedures in dosimetry and of the high quality assurance of blood irradiators has been pointed out. The most recent requirements in this respect have been presented.

    McHenry, Leemon; Khoshnood, Mellad

    2014-01-01

    This article presents an overlooked case of research misconduct and violations of basic principles of medical and business ethics. When Bayer's Cutter Laboratories realized that their blood products, Factor VIII and IX or antihemophiliac factor (AHF), were contaminated with human immunodeficiency virus (HIV), the financial investment in the product was considered too high to destroy the inventory. Cutter misrepresented the results of its own research and sold the contaminated AHF to overseas markets in Asia and Latin America without the precaution of heat treating the product recommended for eliminating the risk. As a consequence, hemophiliacs who infused the HIV-contaminated Factor VIII and IX tested positive for HIV and developed AIDS. PMID:24785997

    2010-11-01

    Full Text Available Millions of blood products are transfused every year; many lives are thus directly concerned by transfusion. The three main labile blood products used in transfusion are erythrocyte concentrates, platelet concentrates and fresh frozen plasma. Each of these products has to be stored according to its particular components. However, during storage, modifications or degradation of those components may occur, and are known as storage lesions. Thus, biomarker discovery of in vivo blood aging as well as in vitro labile blood products storage lesions is of high interest for the transfusion medicine community. Pre-analytical issues are of major importance in analyzing the various blood products during storage conditions as well as according to various protocols that are currently used in blood banks for their preparations. This paper will review key elements that have to be taken into account in the context of proteomic-based biomarker discovery applied to blood banking.

    In 2013, the National Heart, Lung, and Blood Institute assembled a working group on epidemiology and population sciences from its Advisory Council and Board of External Experts. The working group was charged with making recommendations to the National Heart, Lung, and Blood Advisory Council about how the National Heart, Lung, and Blood Institute could take advantage of new scientific opportunities and delineate future directions for the epidemiology of heart, lung, blood, and sleep diseases. Seven actionable recommendations were proposed for consideration. The themes included 1) defining the compelling scientific questions and challenges in population sciences and epidemiology of heart, lung, blood, and sleep diseases; 2) developing methods and training mechanisms to integrate "big data" science into the practice of epidemiology; 3) creating a cohort consortium and inventory of major studies to optimize the efficient use of data and specimens; and 4) fostering a more open, competitive approach to evaluating large-scale longitudinal epidemiology and population studies. By building on the track record of success of the heart, lung, blood, and sleep cohorts to leverage new data science opportunities and encourage broad research and training partnerships, these recommendations lay a strong foundation for the transformation of heart, lung, blood, and sleep epidemiology.

    We consider a class of policies for stocking hospital blood banks with units of random donor platelet concentrate ('Platelets') based upon scheduled daily deliveries from a regional blood center to replenish the platelet inventory to a fixed 'base stock' level. The measures of interest are the 'shortage rate' (the proportion of days for which the on-hand inventory at the hospital blood bank is insufficient to meet the demand) and the 'outdate rate' (the proportion of total units shipped which are not transfused within the usable life span of 5 days). Our principal results give a predictive model which relates the base stock level to the shortage rate and outdate rate. Our model uses only the mean daily demand as a parameter. It provides a basis to unify the results from other studies which have demonstrated improvements in platelet inventory management in particular hospitals and blood centers. PMID:1752123

  15. Blood Donors on Medication - an Approach to Minimize Drug Burden for Recipients of Blood Products and to Limit Deferral of Donors.

    Becker, Christian D K; Stichtenoth, Dirk O; Wichmann, Michael G; Schaefer, Christof; Szinicz, Ladislaus

    2009-01-01

    BACKGROUND: Blood products derived from donors on medication can contain drugs which might pose a risk for the recipients or influence the quality of the product itself. MATERIAL AND METHODS: To judge the eligibility of blood donors on medication, 4 drug classes have been formed with respect to their pharmacological properties, and blood products have been divided in accordance with their single-donor plasma contents. RESULTS: For drugs with dose-dependent pharmacodynamics, no deferral periods are necessary for donation of blood products containing less than 50 ml single-donor plasma for application to adults. Waiting periods of t(max) + 5 t(1/2) were calculated for the other blood products. Teratogenic drugs do not require special considerations (exception: retinoids, thalidomide and lenalidomide, dutasteride or finasteride with waiting periods for all blood products). A deferral period of t(max) + 24 t(1/2) is proposed for every blood product from blood donors on genotoxic drugs. Drugs without systemic effects can be neglected. Irreversible inhibitors of platelet function cause a 10-day waiting period if production of platelet concentrates is intended. CONCLUSION: Donors on medication are allowed to donate blood for blood products containing less than 50 ml plasma of a single donor, like red blood cell concentrates, for the use in adults without deferral periods, except those taking retinoids, thalidomide, lenalidomide, dutasteride, finasteride, or genotoxic drugs.

    AIM: Hyperglycemia commonly seen in liver transplantation (LT) has often been attributed to the dextrose in the storage solution of blood transfusion products. The purpose of the study is to compare the changes of the blood glucose levels in transfused and non-transfused patients during LT. METHODS: A retrospective study on 60 biliary pediatric patients and 16 adult patients undergoing LT was carried out. Transfused pediatric patients were included in Group Ⅰ (GI), those not transfused in Group Ⅱ (GⅡ). Twelve adult patients were not given transfusion and assigned to Group Ⅲ (GⅢ); whereas, four adult patients who received massive transfusion were assigned to Group Ⅳ (GⅣ). The blood glucose levels, volume of blood transfused, and the volume of crystalloid infused were recorded, compared and analyzed. RESULTS: Results showed that the changes in bloodglucose levels during LT for both non-transfused and minimally transfused pediatric groups and non-transfused and massively-transfused adult groups were almost the same. CONCLUSION: We conclude that blood transfusion does not cause significant changes in the blood glucose levels inthis study.

    Enzymatic removal of blood group ABO antigens to develop universal red blood cells (RBCs) was a pioneering vision originally proposed more than 25 years ago. Although the feasibility of this approach was demonstrated in clinical trials for group B RBCs, a major obstacle in translating this technology to clinical practice has been the lack of efficient glycosidase enzymes. Here we report two bacterial glycosidase gene families that provide enzymes capable of efficient removal of A and B antigens at neutral pH with low consumption of recombinant enzymes. The crystal structure of a member of the alpha-N-acetylgalactosaminidase family reveals an unusual catalytic mechanism involving NAD+. The enzymatic conversion processes we describe hold promise for achieving the goal of producing universal RBCs, which would improve the blood supply while enhancing the safety of clinical transfusions.

    This paper presents both quality requirements and indications for use of leucocyte-filtered, cytomegalovirus antibody negative and irradiated cellular blood products at Rikshospitalet. Emphasis is placed on the use of standardized buffycoat depleted red cells or platelet concentrates for filtration, and the selection of leucocyte filters with high capacity and ease of bedside application. Leucocyte counts as low as 1-2 10(5) per unit are recommended after filtration in order to avoid HLA-antibody production. For bedside filtration, our choice was RC100 and PL100 (Pall) for red cells and platelets respectively. For laboratory use we prefer, for economic reasons, to use Sepacell R500 (Asahi) and Imugard IG500 (Terumo) for red cells and platelets respectively. Leucocyte-filtered blood products are considered indicated in all pre-transplant transfusions, in post-transplant HLA-sensitized patients, in other patients with febrile transfusion reactions, and in patients with an expected protracted platelet requirement. CMV antibody negative products are recommended for all immuno-deficient patients and pregnant women negative for CMV antibody. Irradiated blood products are used in the treatment of immuno-deficient patients receiving large amounts of blood, and in all severely immuno-compromised patients. In emergency situations where CMV antibody negative and/or irradiated blood products cannot be supplied, leucocyte filtration is suggested. PMID:2154061

  8. Blood Levels of Zinc in Creole Horses Used in Sera Production

    International Nuclear Information System (INIS)

    Using Neutron Activation Analysis Zn concentrations were determined in blood of horses (Creole breed). No significant difference was observed between male (0.0029±.0007 gL-1) and female (0.0031±.0011 gL-1) animals. These data are an important support to understand the physiological functions of Zn in blood during the process of sera production at Butantan Institute (Sao Paulo, Brazil) using horses.

    Full Text Available Aedes aegypti is the major vector of dengue, yellow fever and chikungunya viruses that put millions of people in endemic countries at risk. Mass rearing of this mosquito is crucial for strategies that use modified insects to reduce vector populations and transmission of pathogens, such as sterile insect technique or population replacement. A major problem for vector mosquito mass rearing is the requirement of vertebrate blood for egg production since it poses significant costs as well as potential health hazards. Also, regulations for human and animal use as blood source can pose a significant obstacle. A completely artificial diet that supports egg production in vector mosquitoes can solve this problem. In this study, we compared different blood fractions, serum and red blood cells, as dietary protein sources for mosquito egg production. We also tested artificial diets made from commercially available blood proteins (bovine serum albumin (BSA and hemoglobin. We found that Ae. aegypti performed vitellogenesis and produced eggs when given whole bovine blood, serum, or an artificial diet containing BSA. Conversely, egg production was impaired after feeding of the red blood cell fraction or an artificial diet containing only hemoglobin. We also found that egg viability of serum-fed mosquitoes were comparable to that of whole blood and an iron supplemented BSA meal produced more viable eggs than a meal containing BSA alone. Our results indicate that serum proteins, not hemoglobin, may replace vertebrate blood in artificial diets for mass mosquito rearing.

  11. Optimization of sugar and blood feeding regimen in Anopheles gambiae mass production system

    International Nuclear Information System (INIS)

    The sterile insect technique (SIT) is being developed for the control of malaria transmitting mosquitoes. Critical to the success of applying the SIT is the establishment of standardized mass production systems for the target species. As part of efforts to develop standardised mass production systems for malaria vectors, this project sought to optimize adult blood and sugar feeding in a mass production system. Different sugar types (glucose, sucrose and honey) were evaluated at 6% and 10% concentrations in water to determine the best sugar diet and concentration for feeding adult An. gambiae. Different blood feeding methods, restrained Guinea pig, anaesthetised Guinea pig and human arm feeding were evaluated. Adult survival, female insemination and egg production were used as criteria to determine optimum sugar and blood feeding. The effect of anaesthetics on blood feeding response and egg production of female An. gambiae was determined by comparing feeding response and egg production of females fed with anaesthetised Guinea pigs as against physically restrained Guinea pigs (Control). The specific effect of different anaesthetic agents on blood feeding response and egg production of female mosquitoes were was also determined by comparing the feeding response and egg production of females fed with either Ketamine/Xylazine anaesthetised Guinea pigs or Ketamine/Diazepam anaesthetised Guinea pigs. Effects due to sugar types and concentrations on percentage survival of male and female mosquitoes were observed to be significant at (p 0.05). However, human ann feeding (HAP) method and Ketamine/Xylazine (KX) anaesthetics fed for 25 minutes recorded higher percentage feeding (76.0% and 68.0% respectively) and egg production of 19.0% and 20.8% respectively. Anaesthetised Guinea pig feeding (AGF) of adults for 15 minutes followed closely with 60.0% and 15.1% blood feeding and egg production respectively whilst restrained Guinea pig feeding (RGF) method and Ketamine

    AIM: To investigate whether increased plasma L-homocysteine (Hcy) level could promote monocyte chemoattract antprotein-1 (MCP-1) and interleukin-8 (IL-8) in cultured whole blood. METHODS: Human whole blood or differenttype of peripheral blood cells from health volunteers were incubated with Hcy and/or the inhibitors. MCP-1 and IL-8 level were measured by ELISA assay. RESULTS: Hcy 10-1000 μmol/L induced production of MCP-1and IL-8 in cultured human whole blood (P<0.05). The major cellular source of these chemokines comed from monocytes. Meanwhile,Hcy also promoted the upregulation of MPO level even at the 10 μmol/L in the cultured whole blood.The intracellular ROS, particular the OH radicals, play extremely important role in the Hcy-induced MCP-1 and IL-8 production. CONCLUSION: Increased Hcy level in plasma (hyperhomocysteinemia) induced MCP-1 and IL-8secretion in cultured human whole blood, especially in monocytes via oxidative stress mechanism,

  13. X-ray irradiation on blood products for the purpose of prevention of PT-GVHD

    International Nuclear Information System (INIS)

    X-ray irradiation on blood products is a common method to prevent the risk of inducing PT-GVHD, and has recently become to be used in Japan. We have tried X-ray irradiation on WB, CRC and PC using HITACHI X-ray Irradiation Apparatus MBR1520R, and studied its practical usefulness. In case of irradiation on blood bags as the minimum dose of 1,500 rads, these conditions are thought to be practical: 1) the use of 1.0 mm Al filter, 2) the distance of 550 nm from X-ray source, and 3) irradiation on 4 bags at the same time. But, it has also been noticed that total doses and qualities of X-ray absorbed into blood were different between upper and lower side of the bag. Bloods on upper side absorbed much doses and a wide range of X-ray, on the other hand, bloods on lower side absorbed less doses and hard X-ray. In these conditions, irradiated lymphocytes showed a complete inhibition of thymidine uptake in MLC test, still had 15% of activity in PHA stimulation. The qualities of other blood components have not changed before and after irradiation. X-ray irradiation is useful in a routine work of blood center, but problems of proper doses and a uniformity of irradiation are remained to be solved. (author)

    Full Text Available Background & objectives: Different methods have been developed for tsetse and trypanosomiasis control oreradication but all these have their specific advantages and limitations. However, a combination of methodscould be used as part of an Area-wide Integrated Pest Management (AWPM. The sterile insect technique(SIT as a technique of choice for eradication of tsetse flies requires mass production of flies in the laboratories.Since tsetses are exclusively haemotophogous insects, a quality blood diet is needed for maintenance of flieswith optimum production. The aim of this study was to establish the optimum storage time of blood diet fortsetse colonies.Methods: A total of 450 flies Glossina austeni were fed on different batches of blood (collected in 2004, 2005,2006, 2007 and 2008 three times a week. Pupae were collected daily and mortality checks were done onweekly basis. The quality of the blood diet was measured by observation of tsetse production parametersincluding survival, pupae production and size.Results: The survival of flies fed on 2004 and 2006 batches had lower survival compared to the rest of thebatches. Also the 2005 batch had a significant higher number of pupae compared to the production in othertreatments. The 2004 and 2005 batches had more of small pupae (class A & B compared to the other batches.Interpretation & conclusion: There was a significant difference between the blood batches and the productionparameters were better in the last three years, i.e. 2008, 2007 and 2006. Therefore, this study recommendsthree years to be an optimum storage time for blood diet under regional conditions. Also the storage temperatureconditions should remain stable at –20ºC.

  15. Plasma fractionation for blood products: isolation and purification of coagulating factors, albumin and immunoglobulin

    International Nuclear Information System (INIS)

    Approximately 12 million liters of human plasma are fractionated world-wide annually. However, with the market for clotting factors and other haemoderivatives steadily increasing from year to year, the amount processed will also increase correspondingly to keep up with the demand. In Malaysia, part of the need for the blood products are obtained commercially but a major portion of the requirement involves sending the plasma collected by the National Blood Centre to Australia for processing. Following purification and isolation of the blood products, they are sent back to Malaysia for local consumption. As yet there are no plasma fractionation plants in the South East Asia region, it would be advantageous to establish a local fractionation plant as it would be able to cater for local demands of the haemoderivatives and thus reduces the cost of importing these products. Besides, this facility will be able to provide contract fractionation services to the surrounding region. Early work in MINT has started in trying to purify plasma obtained from rats. Purification of the plasma was performed by using Sephadex G-25 column. Short term objective of this project is to develop the technique of extraction, fractionation and purification of blood products such as albumin, globulin and clotting factors (Factor VIII and Factor IX). The long term emphasis will be to scale up the production facility to a pilot plant stage and eventually to a national fractionation and purification plant. (Author)

    The blood sugar level was evaluated in patients with insulin-independent diabetes mellitus and obesity, and in normal volunteers, during 3 h with a 30-min interval before and after food loading containing 50 g of carbohydrates. It has been found that 17 food products studied produce varying effects on the blood glucose level regardless of the content of starch and sugars in them. Pure glucose, boiled rice, potatoe, white bread, boiled bean, pastry, honey and sugar produce the highest glycemic effect. Milk, ice cream, boiled lens and noodles produce a moderate effect on the blood sugar level both in normal subjects and in patients with diabetes mellitus and obesity. The increase of the glucose blood level after intake of food products was significantly higher in patients with diabetes mellitus as compared to those with obesity and normal volunteers. Milk products, lens, macaroni and millet are most promising for patients with diabetes mellitus due to their moderate influence on the blood glucose content. PMID:2042318

    Recombinant clotting factors are important biotherapeutics that Pfizer has produced and marketed for over fifteen years. Owing to the complexity of the structure and function of these blood factors, it can be challenging to achieve the required product quality and manufacturing productivity. The article highlights the semi-continuous and continuous cell culture processes employed by Pfizer for the production of BeneFIX and ReFacto AF. The benefits of such processes, the challenges of maintaining an aseptic production culture for extended periods, and batch definition are discussed in this article. PMID:25738489

    An excellent monitor of the immune balance of peripheral circulating cells is to determine their cytokine production patterns in response to stimuli. Using flow cytometry, a positive identification of cytokine producing cells in a mixed culture may be achieved. Recently, the ability to assess cytokine production following a whole-blood activation culture has been described. In this study, whole blood activation was compared to traditional PBMC activation and the individual cytokine secretion patterns for both T cells, T cell subsets and monocytes was determined by flow cytometry. RESULTS: For T cell cytokine assessment (IFNg/IL-10 and IL-21/L-4) following PMA +ionomycin activation: (1) a Significantly greater percentages of T cells producing IFNgamma and IL-2 were observed following whole-blood culture and (2) altered T cell cytokine production kinetics were observed by varying whole blood culture times. Four-color analysiS was used to allow assessment of cytokine production by specific T cell subsets. It was found that IFNgamma production was significantly elevated in the CD3+/CD8+ T cell population as compared to the CD3+/CD8- population following five hours of whole blood activation. Conversely, IL-2 and IL-10 production were Significantly elevated in the CD3+/CD8- T cell population as compared to the CD3+/CD8+ population. Monocyte cytokine production was assessed in both culture systems following LPS activation for 24 hours. A three-color flow cytometric was used to assess two cytokines (IL-1a/IL-12 and TNFa/IL-10) in conjunction with CD14. Nearly all monocytes were stimulated to produce IL-1a, IL-12 and TNFa. equally well in both culture systems, however monocyte production of IL-10 was significantly elevated in whole blood culture as compared to PBMC culture. IL-12 producing monocytes appeared to be a distinct subpopulation of the IL-1a producing set, whereas IL-10 and TNFa producing monocytes were largely mutually exclusive. IL-10 and TNFa producing

    Bovine papillomavirus (BPV) is an oncogenic virus with mucous and epithelial tropism. Possible productive virus infection in other tissues, such as blood, has been hypothesized. In order to investigate this possibility, three samples of skin papillomas and blood were collected from bovines with BPV infection and five samples of peripheral blood and one sample of normal tissue were collected from a calf without BPV infection. Peripheral blood mononuclear cells (PBMCs) were isolated from whole blood and examined by reverse transcription-polymerase chain reaction, immunofluorescence, in situ hybridization, and electron microscopy. The tissue samples were examined for histopathological and immunohistochemical features. The skin papillomas showed the presence of DNA sequences of BPV-2, BPV-11, and a putative virus type. The blood samples showed DNA sequences of BPV-1, 2, and 4 simultaneously. Immunohistochemistry showed BPV L1 protein in both epithelium and stroma and BPV E2 protein in koilocytes. In situ hybridization confirmed the presence of BPV DNA in PBMCs and immunofluorescence showed nuclear labeling of E2 and L1 BPV proteins in PBMCs. The transcription analysis revealed transcripts of BPV-1 L1, BPV-2 L2, and BPV-4 E7 in blood and papilloma samples of BPV-infected cattle. The comet assay revealed high levels of host cell DNA damage upon BPV infection. Electron microscopy analysis of PBMCs identified the presence of particles in the cytoplasm that are consistent with papillomavirus in size and shape. The productive infection of PBMCs with BPV has been previously discussed and this study provides evidence indicating that PBMCs are a target of BPV. PMID:26681018

  2. Trigeminal origin or B-preprotachykinin products in feline pial blood vessels

    International Nuclear Information System (INIS)

    A specific and sensitive radioimmunoassay measured the presence of immunoreactive neurokinin A within feline and human pial arteries. Immunoreactivity exhibited a retention time identical to that of synthetic peptide when acid extracts from feline and human blood vessels were subjected to reverse-phase high-performance liquid chromatography. As shown previously for substance P, levels of immunoreactive neurokinin A decreased significantly in the vessels from the ipsilateral rostral circle of Willis l9-24 days following unilateral trigeminal ganglionectomy. Hence, trigeminal projections to cerebral blood vessels contain both products of B-preprotachykinin mRNA. (author)

    The transfusion of red blood cells (RBCs) is now considered a well-settled and essential therapy. However, some difficulties and constraints still occur, such as long-term blood product shortage, blood donor population aging, known and yet unknown transfusion-transmitted infectious agents, growing cost of the transfusion supply chain management, and the inescapable blood group polymorphism barrier. Red blood cells can be now cultured in vitro from human hematopoietic, human embryonic, or human-induced pluripotent stem cells (hiPSCs). The highly promising hiPSC technology represents a potentially unlimited source of RBCs and opens the door to the revolutionary development of a new generation of allogeneic transfusion products. Assuming that in vitro large-scale cultured RBC production efficiently operates in the near future, we draw here some futuristic but realistic scenarios regarding potential applications for alloimmunized patients and those with a rare blood group. We retrospectively studied a cohort of 16,486 consecutive alloimmunized patients (10-year period), showing 1 to 7 alloantibodies with 361 different antibody combinations. We showed that only 3 hiPSC clones would be sufficient to match more than 99% of the 16,486 patients in need of RBC transfusions. The study of the French National Registry of People with a Rare Blood Phenotype/Genotype (10-year period) shows that 15 hiPSC clones would cover 100% of the needs in patients of white ancestry. In addition, one single hiPSC clone would meet 73% of the needs in alloimmunized patients with sickle cell disease for whom rare cryopreserved RBC units were required. As a result, we consider that a very limited number of RBC clones would be able to not only provide for the need for most alloimmunized patients and those with a rare blood group but also efficiently allow for a policy for alloimmunization prevention in multiply transfused patients.

  7. Blood Collection from Local Abattoirs for Mass Production of Tsetse Flies to be used in the Sterile Insect Technique

    International Nuclear Information System (INIS)

    The mass production of tsetse flies (Glossina spp.) for the sterile insect technique (SIT) requires a supply of quality blood. For some years already cattle blood has been used as food for laboratory reared flies. The blood is collected from an abattoir using standard procedures. The collection procedures, handling and storage require aseptic conditions to avoid contamination of the blood, which could be fatal to the flies. Fly mortality caused by low quality blood endangers the success of mass rearing. To rear healthy flies with good survival and production the blood should be of good quality - free of contamination and with a packed cell volume (PCV) above 25%. The present work involved the seasonal collection of blood from abattoirs in the United Republic of Tanzania (Tanga, Arusha, Dodoma, Dar-es-salaam). Dodoma was identified as having the best conditions for blood collection. To assess the quality of the blood as a diet for tsetse, blood was screened for the presence of bacteria, and the pathogens were identified. Protocols were developed for blood quality assurance.

    Full Text Available Corticoids are well known for their immunosuppressive properties. Interleukin-10 (IL-10 is an intrinsic antiinflammatory peptide in immune diseases, originally identified as cytokine synthesis inhibitory factor. We examined the effect of hydrocortisone sodium succinate (HSS on the production of IL-10 by human peripheral blood mononuclear cells (PBMCs. PBMCs from healthy volunteers and cancer-burden patients were preincubated separately with or without HSS for 1 h, then stimulated with 5 microg/ml lipopolysaccharide (LPS. Production of IL-10 by human PBMCs was detected with LPS stimulation and its production was higher in cancer-burden patients than in normal volunteers, although this was not statistically significant. HSS suppressed production of IL-10 by LPS-stimulated PBMCs in a dose-dependent manner both in normal volunteers and in cancer-burden patients. These results indicate that, in addition to their antiinflammatory properties, corticoids act to restore the immunosuppressive states even in cancer-burden states.

    Full Text Available Blood-derived products are commonly administered to horses and humans to treat many musculoskeletal diseases, due to their potential antioxidant and anti-inflammatory effects. Nevertheless, antioxidant effects have never been shown upon horse synovial fluid cells in vitro. If proved, this could give a new perspective to justify the clinical application of blood-derived products. The aim of the present study was to investigate the antioxidant effects of two blood-derived products - plasma (unconditioned blood product - UBP and a commercial blood preparation (conditioned blood product - CBP¹ - upon stimulated equine synovial fluid cells. Healthy tarsocrural joints (60 were tapped to obtain synovial fluid cells; these cells were pooled, processed, stimulated with lipopolysaccharide (LPS or phorbol 12-myristate 13-acetate (PMA, and evaluated by flow cytometry for the production of reactive oxygen species (ROS. Upon addition of any blood-derived product here used - UBP and CBP - there was a significant decrease in the oxidative burst of synovial fluid cells (P<0.05. There was no difference between UBP and CBP effects. In conclusion, treatment of stimulated equine synovial cells with either UBP or CBP efficiently restored their redox equilibrium.

    Full Text Available Milk production, total blood cholesterol concentration and activity ofgamma-glutamyl-transferase (GGT and glutation peroxidase (GPx in blood of Simmental cows was monitored during two control periods (first control period - May 2004; second control period - June 2004. The objective was to determine a relationship between milk production and particular blood parameters, and their possible implementation as an indicator of milk production. Twelve Simmental cows from small-scale dairy farm in Zagreb County were included in the study. Cows originated from the same herd andwere roughly of the same parity and stage of lactation. The average milk production and total blood cholesterol concentration were significantly higher in May then in June (20,55 L/d vs. 15,44 L/d; 4,55 mmol/L vs. 3,96 mmol/L, respectively, whereas the GPx and GGT activity was significantly lower in May in comparison with June (GPx=1720,66 U/L vs. GPx=1808 U/L, and GGT = 20,11 U/L vs. 23,22 U/L, respectively. A positive correlation between the milk production and the total blood cholesterol level was detected (r=0,58. The total blood cholesterol concentration in the blood plasma mighthave been one of the indicators of production performance in the Simmental cows herd, whereas the activity of stated enzymes may specify the nutritional status thereof the milk production depends on.

    Full Text Available Artificial blood is a product made to act as a substitute for red blood cells. While true blood serves many different functions, artificial blood is designed for the sole purpose of transporting oxygen and carbon dioxide throughout the body. Depending on the type of artificial blood, it can be produced in different ways using synthetic production, chemical isolation, or recombinant biochemical technology. Development of the first blood substitutes dates back to the early 1600s, and the search for the ideal blood substitute continues. Various manufacturers have products in clinical trials; however, no truly safe and effective artificial blood product is currently marketed.

    There are more vaccines in development, against a greater number of pathogens, than ever before. A challenge with this exceptional level of activity and investment is how to select and resource the most promising approaches to have the most significant impact on public health. The WHO Product Development for Vaccines Advisory Committee (PDVAC) was established in 2014 to provide strategic advice and recommendations to WHO for vaccines in clinical development that could have a significant impact on public health in low and middle income countries. On 7-9th September 2015, PDVAC was convened for the second time, when the committee reviewed vaccine developments in 24 disease areas. This report summarises the key recommendations from that consultation. PMID:26993336

    Full Text Available Abstract. Alpha-1-acid glycoprotein (orosomucoid is a multifunctional acute phase reactant belonging to the family of lipocalines from plasma alpha-2 globulin fraction. In present study, we investigated dosedependent effects of orosomucoid upon secretion of IL-1â, IL-2, IL-3, IL-4 by mononuclear cells from venous blood of healthy volunteers. Mononuclear cells were separated by means of gradient centrifugation, followed by incubation for 24 hours with 250, 500, or 1000 mcg of orosomucoid per ml RPMI-1640 medium (resp., low, medium and high dose. The levels of cytokine production were assayed by ELISA technique. Orosomucoid-induced secretion of IL-1â and IL-4 was increased, whereas IL-3 secretion was inhibited. IL-2 production was suppressed at low doses of orosomucoid, and stimulated at medium and high doses. The effect of alpha-1-acid glycoprotein upon production of IL-2, IL-3 and IL-4 was dose-dependent. Hence, these data indicate that orosomucoid is capable of modifying IL-1â, IL-2, IL-3, and IL-4 secretion by blood mononuclear cells.

  16. Influence of some probiotics on blood components, productive and reproductive performance of japanese quails

    International Nuclear Information System (INIS)

    The current study was conducted to evaluate the effect of adding some probiotics into diets of Japanese quails on productive and reproductive performance, blood constituents, immune response and intestinal wall thickness. A total number of 500 one day old, unsexed Japanese quail chicks were used. Five experimental groups were assigned in the present study, where the 1st group (G1) was provided with protexin at 5 g/litre (5 days weekly). The 2nd group (G2) contained medi stress of 0.75 g/litre (5 days weekly), the 3rd group (G3) was fed a basal diet contained bioaction at 5g/kg, the 4th group (G4) involved a basal diet with active dried yeast (Saccharomyces cerevisiae) at 0.1 g/kg daily and group 5 were fed the basal diet without probiotics supplementation (control). The results showed that the average body weight, egg production and egg weight were significantly increased due to adding probiotics and 0.1g/kg yeast into diets. Feed conversion ratio and mortality were improved significantly and the most improvement was recorded at 1.0% yeast and protexin. Similar improvement was recorded for hatch ability and hatching weight. There were reductions in intestinal wall thickness due to adding 0.1 g/kg yeast or protexin. The values of HI titer against sheep RBCs were increased significantly as compared to the control, which may lead to an enhancement of immune response of Japanese quails. Blood protein, globulin and FSH hormone were increased significantly. In conclusion, adding some probiotics into diets of Japanese quails improved productive, reproductive performance, blood constituents, immune response and intestinal wall thickness

    Blood Transfusion Services are striving to continually improve the efficacy and quality of their blood products whilst also simultaneously diversifying into novel cellular products. For this to be successful the relationships between the various arms of the organisation must be strong and interlinked. As new technologies impact on the products that blood transfusion services supply it should be noted that the interaction between the service and its donor base is also affected by advancing technologies. Social media has fundamentally altered the way in which the public can access information and news, as such blood services must engage and interact appropriately with these new forms of media. As a reflection of these challenges the Scotblood 2015 programme was focussed on service and product improvement, donor engagement and people centred transfusion. This commentary comprises summaries of the presentations, based in part on the abstracts provided by the speakers. PMID:27524267

    This paper presents cost-effectiveness analyses (CEAs) of plasma collection via two alternative methods: whole blood collection (WBC) and erythroplasmapheresis collection (EPC). The objective of the study is to provide an answer to the question 'What is the least-cost method of plasma production'. This question is answered, both from the viewpoint of the blood collection agency (using financial CEA) and from that of 'society' as a whole (using economic CEA). We employ detailed financial data and economic survey data for collections made by a blood collection agency and to WBC and EPC donors in Brisbane, Australia. The results indicate that, despite the superior yield provided by EPC, WBC is actually more cost-effective. This result is robust to thorough sensitivity analysis and arises regardless of whether an economic or financial perspective is taken. We conclude that, ceteris paribus, the cost of recruiting new plasma donors would need to be quite substantial for marginal investments in EPC to be considered cost-effective. PMID:12350045

  19. Peripheral Blood Leukocyte Production of BDNF following Mitogen Stimulation in Early Onset and Regressive Autism

    Directory of Open Access Journals (Sweden)

    Full Text Available Brain-derived neurotrophic factor (BDNF is critical for neuronal differentiation and synaptic development. BDNF is also implicated in the development of psychological disorders including depression, bipolar disorder and schizophrenia. Previously, elevated BDNF levels were observed in neonatal blood samples from infants who were later diagnosed with autism when compared with children who developed normally, suggesting that BDNF may be involved in the development of autism. BDNF is produced by activated brain microglial cells, a cellular phenotype that shares several features with peripheral macrophages, suggesting an important role for the immune system in BDNF production. We hypothesized that under mitogenic stimulation, peripheral blood mononuclear cells obtained from children with autism may have altered BDNF production compared with age-matched typically developing control subjects. In addition, we examined the differences between the production of BDNF in classic/early-onset autism and children who had a regressive form of autism. We show here that plasma levels of BDNF levels are increased in children with autism, especially in early onset autism subjects. Furthermore, under mitogenic stimulation with PHA and LPS, BDNF production is significantly increased in children with autism compared with typically developing subjects. However, stimulation with tetanus toxoid results in a decreased response in children with autism. This data suggest that immune cell-derived production of BDNF could be an important source for the increased BDNF that is detected in some subjects with autism. As a neurotrophic factor produced by immune cells, BDNF could help elucidate the role of the immune system in neurodevelopment and neuronal maintenance, which may be dysregulated in autism.

    2014-01-01

    Background Salmonella enterica serovar Enteritidis (SE), as a major cause of foodborn illness, infects humans mainly through the egg. However, the symptom of laying hens usually is not typical and hard to diagnosis. In the present study, it is studied that the influences of SE infection on layers’ performance, egg quality and blood biochemical indicators. It will help us to improve the strategy to control SE infection in commercial layers. One hundred layers at 20 wk of age were divided into 2 groups, 60 hens for experiment and others for control. The experiment group was fed with the dosage of 108 CFU SE per hen. The specific PCR was used to detect the deposition of SE. On the 8 d after SE infection, 10 hens from the control group and 30 hens from the experimental group were slaughtered to detect the SE colonization. The production performance, egg quality and blood biochemical indices were also analyzed. Results The results showed that the colonization rate of SE was highest in caecum contents (55.17%) and lowest in vagina (17.24%). For the eggs the detection rate of SE was highest on the eggshell (80.00%) and lowest in yolk (18.81%). SE infection had no significant influence on production performance and egg qualities (P > 0.05). The difference of laying rate between the experimental and control groups was less than 0.30%, and both were approximately equal to 82.00%. The blood analysis showed that the aspartic aminotransferase (AST) and alanine aminotransferase (ALT) of experimental group was significantly higher than those of control group (P < 0.05). For experimental and control groups AST values were 236.22 U/l and 211.84 U/l respectively, and ALT values were 32.19 U/l and 24.55 U/l. All of coefficients were less than 20%. The colonization of SE in organs increases the enzyme activities of AST and ALT in blood. Conclusions SE in feed could invade the oviduct and infect the forming eggs. It significantly increased the concentration of ALT and AST in blood

    AIM: To search tools of high blood pressure in the model of nitric oxide (NO)-defective hypertension, and the study focused on the effect of rilmenidine, agonist of imidazoline receptors, which was suggested to modulate central sympathetic outflow. METHODS: Three experimental groups, each consisting of 7 rats, were used: (Ⅰ) rats with inhibition of NO synthase (NOS) by NG-nitro-L-arginine methyl ester (L-NAME) 40 mg.kg-1.d-1 for 4 weeks in drinking water, (Ⅱ) rats with inhibited NOS as in group Ⅰ, plus agonist of imidazoline receptors rilmenidine 3mg.kg-1·d-1 for 4 weeks by gavage, and (Ⅲ) control rats. Systolic blood pressure was measured weekly noninvasively.At the end of experiment aortic ring isometric tension was followed, NOS expression (aorta, left ventricle), and NOS activity (left ventricle and brain) were determined. RESULTS: In the group Ⅰ systolic blood pressure increased significantly, aortic ring relaxation to acetylcholine was significantly attenuated. Rilmenidine administered simultaneously with L-NAME (group Ⅱ) prevented the increase of blood pressure which did not differ significantly from control values; aortic ring relaxation to acetylcholine did not differ from control. No change in NOS expression (aorta and left ventricle) was found in groups Ⅰ and Ⅱ. Significant decline in NOS activity (left ventricle and brain) was found in groups Ⅰ and ⅡⅡ. CONCLUSION: Rilmenidine has a remarkable role in NO-defective hypertension,possibly by inhibiting central sympathetic outflow and by affecting receptors in vascular smooth muscle also. The prime cause of hypertension in this experimental model - the compromised production of NO due to inhibition of NOS - was not affected by rilmenidine.

    high population density and thereby reduce the theoretical advantage of ATK (but definitely would not nullify it!). It is equally plausible, however, that this agent would behave like a prion, non-sexual transmission, or like a West-Nil virus, a non-contagious vector-transmitted agent. For PTK this would mean a relative risk up to 4 times (PTK from 4 BCs) or 5 times (PTK from 5 BCs) higher than the risk estimated by the Robert-Koch-Institute. If, taking the passive surveillance data and the changing variables (donor frequency, donor population, and donor location) into account, the risk of transmission of an infection via ATK (exposure to 1 donor) with HIV, HCV, and HBV moves closer to the higher risk of PTK (exposure to 4 or 8 donors, in case of double ATK per patient), this result of the risk model calculation by no means indicates any equivalency between PTK and ATK with respect to the risk of transmission of infection. The modifiable variables of donor frequency, donor population, and donor location need to be modified, as scientific deductions, in such a way that the avoidable risk of ATK which is influenced by these variables can be corrected to the minimum risk of a transmission of infection of HIV, HBV, and HCV via ATK in comparison to PTK. The minimum risk of a possible transmission of infection via ATK (exposure to 1 donor) is the basic intrinsic risk of each individual blood donation. The basic intrinsic risk increases relative to the number of blood donations or exposure to donors (PtK has an unalterable, production-dependent exposure to 4 or 8 donors). Let us consider a 1:1.000 prevalence for a new pathogen, which is spread equally in each donor population (apheresis and whole blood) and the present case of approximately 500,000 transfused platelet concentrates in Germany. This means that for the production of 4 PTK about 2 million donations are processed, 2,000 infectious Buffy-Coats are obtained and, thereby, 2,000 infectious PTK. In the case of ATK

    In spite of reports on cytokines induction by the Brucella DNA in murine model, there is no comparison between pathogenic and appropriate vaccine strains in human. We investigated the cytokines profile of human peripheral blood mononuclear cells (PBMCs) induced by DNA extracted from pathogenic isolates of Brucella melitensis and B. abortus as well as Rev1 and S19; the appropriate vaccine strains. It was observed that despite differential induction of Interleukin(IL)-12 and IL-10 production, identical IL-12/IL-10 concentration ratio was obtained by all Brucella strains DNAs that was 2 after 24 h and 4 after 5 days of incubation. In addition, IL-2 and Interferon(IFN)-gamma production were profoundly increased compared to the medium at day 3 and 5 respectively but IFN-alpha was not induced. Therefore, Brucella strains DNAs are Th1 inducing component with similar pattern in human PBMCs. PMID:17008080

    Florida manatees (Trichechus manatus latirostris) are exposed to many conditions in their habitat that may adversely impact health and impair immune function in this endangered species. In an effort to increase the current knowledge base regarding the manatee immune system, the production of an important reactive nitrogen intermediate, nitric oxide (NO), by manatee peripheral blood mononuclear cells (PBMC) was investigated. PBMC from healthy captive manatees were stimulated with LPS, IFN-gamma, or TNF-alpha, either alone or in various combinations, with NO production assessed after 24, 48, 72, and 96 h of culture. NO production in response to LPS stimulation was significantly greater after 48, 72, or 96 h of culture compared to NO production after 24h of culture. A specific inhibitor of inducible nitric oxide synthase (iNOS), L-NIL (L-N(6)-(1-iminoethyl)lysine), significantly decreased NO production by LPS-stimulated manatee PBMC. Manatee specific oligonucleotide primers for iNOS were designed to measure expression of relative amounts of mRNA in LPS-stimulated manatee PBMC from captive manatees. NO production by PBMC from manatees exposed to red tide toxins was analyzed, with significantly greater NO production by both unstimulated and LPS stimulated PBMC from red tide exposed compared with healthy captive or cold-stress manatees. Free-ranging manatees produced significantly lower amounts of nitric oxide compared to either captive or red tide rescued manatees. Results presented in this paper contribute to the current understanding of manatee immune function and represent the first report of nitric oxide production in the immune system of a marine mammal.

  7. Effects Of Copper Sulphate On Productive, Reproductive Performance And Some Blood Constituents Of Laying Japanese Quail

    International Nuclear Information System (INIS)

    The present study was carried out at the Poultry Research Farm of Nuclear Research Centre, Atomic Energy Authority, Egypt, from February to September 2008 to study the effect of four levels of copper sulphate supplementation (CuSO4,0,200,300 and 400 mg/kg diet) on some of productive and reproductive performance, egg weight, some blood constituents and economical efficiency of laying Japanese quails. Four diets were used from one week of age until mature and egg production stage (30 days age). Body weight was recorded weekly while egg production and egg weight were recorded daily. Resulted eggs were incubated to study the effect of Cu supplementation on fertility, embryonic mortality percentage and hatchability rate. At the end of experiment (6 months of age),10 birds of each group (5 males and 5 females) were slaughtered to study the effect of Cu supplementation on some organs weights such as carcass, liver, heart, gizzard, small intestine, proventricular, ovary, oviduct and tests. Blood components and triiodothyronine (T3) levels were determined. The results showed that body weight was significantly lowered in groups 3 (300 mg) and 4 (400 mg) than group 2 (200 mg). Liver, heart, ovary and oviduct weights were also depressed at the two highest levels of Cu supplementation (groups 3 (300 mg) and 4 (400 mg)). In addition, high level of Cu supplements ≥ 300 mg Cu/kg decreased egg production, hatchability and fertility percentage while they were good or better in group had 200 mg Cu/kg. On the other hand, G2 (200 mg Cu/kg) had the smallest egg weight than other groups. Non-significant effects were observed in serum total protein, albumin and globulin of laying quails had the different levels of CuSO4 except G3 that had the lowest values. Reverse trend was observed in serum triglycerides, cholesterol and triiodothyronine (T3) in groups supplemented high dietary CuSO4. In conclusion, copper is often added to poultry diets at prophylactic concentration of 200 mg

    To compare the effect on blood glucose concentrations of guar incorporated into crispbreads with that of unprocessed high-fibre foods groups of four to six diabetics took a total of seven test breakfasts on separate days. By comparison with a breakfast of wholemeal bread and cheese, guar crispbread combined with bread reduced the area under the glucose response curve to 51% (p soya beans reduced the area to 65% (p soya beans to 25% (p soya beans with lentils to 29% (p < 0.002). Porridge and cornflake breakfasts showed no difference. The favourable results with leguminous seeds may not make such meals more acceptable than meals of guar products, but a combination of leguminous seeds and guar may allow smaller and more acceptable amounts of both to be used.

    As part of an overall design of a new, standardized RFID-enabled blood transfusion medicine supply chain, an assessment was conducted for two hospitals: the University of Iowa Hospital and Clinics (UIHC) and Mississippi Baptist Health System (MBHS). The main objectives of the study were to assess RFID technological and economic feasibility, along with possible impacts to productivity, quality and patient safety. A step-by-step process analysis focused on the factors contributing to process "pain points" (errors, inefficiency, product losses). A process re-engineering exercise produced blueprints of RFID-enabled processes to alleviate or eliminate those pain-points. In addition, an innovative model quantifying the potential reduction in adverse patient effects as a result of RFID implementation was created, allowing improvement initiatives to focus on process areas with the greatest potential impact to patient safety. The study concluded that it is feasible to implement RFID-enabled processes, with tangible improvements to productivity and safety expected. Based on a comprehensive cost/benefit model, it is estimated for a large hospital (UIHC) to recover investment from implementation within two to three years, while smaller hospitals may need longer to realize ROI. More importantly, the study estimated that RFID technology could reduce morbidity and mortality effects substantially among patients receiving transfusions. PMID:19894488

    2001-01-01

    An excellent monitor of the immune balance of peripheral circulating cells is to determine their cytokine production patterns in response to stimuli. Using flow cytometry a positive identification of cytokine producing cells in a mixed culture may be achieved. Recently, the ability to assess cytokine production following a wholeblood activation culture has been described. We compared whole blood culture to standard PBMC culture and determined the individual cytokine secretion patterns for both T cells and monocytes via flow cytometry. For T cells cytokine assessment following PMA +ionomycin activation: (1) a significantly greater percentages of T cells producing IFNgamma and IL-2 were observed following whole-blood culture; (2) altered T cell cytokine production kinetics were observed by varying whole blood culture times. In addition, a four-color cytometric analysis was used to allow accurate phenotyping and quantitation of cytokine producing lymphocyte populations. Using this technique we found IFNgamma production to be significantly elevated in the CD3+/CD8+ T cell population as compared to the CD3+/CD8- population following five hours of whole blood activation. Conversely, IL-2 and IL-10 production were significantly elevated in the CD3+/CD8- T cell population as compared to the CD3+/CD8+ population. Monocyte cytokine production was assessed in both culture systems following LPS activation for 24 hours. A three-color flow cytometric was used to assess two cytokines in conjunction with CD 14. The cytokine pairs used for analysis were IL-1a/IL-12, and IL-10ITNFa. Nearly all monocytes were stimulated to produce IL-1a, IL-12 and TNFalpha equally well in both culture systems. Monocyte production of IL-10 was significantly elevated following whole blood culture as compared to PBMC culture. IL-12 producing monocytes appeared to be a distinct subpopulation of the IL-1a producing set, whereas IL-10 and TNFa producing monocytes were largely mutually exclusive. IL-10 and

    Full Text Available The aim of this study was to investigate the effect of live yeast culture (Saccharomyces cerevisiae Sc 47 on milk yield, milk composition and some blood parameters of dairy cows during their early lactation on farm conditions. The live yeast culture was given in the diet of heifers and cows (5 g day-1 solid Actisaf for 14 days before calving and exclusively for the treated cows 12 g day-1 dissolved in 500 ml of water, during 14 days after calving. The experiment took until 100th day of lactation on farm conditions. Yeast culture supplementation was the most effective for the performance of primiparous cows: It was advantageous for blod plasma parameters: decreased the beta-hydroxy butyrate (BHB content and free fatty acids (FFA which indicated the protection of the animals against ketosis or other metabolic disorders. Increased the daily milk production and the lactose /glucose content of the milk. The live yeast culture increased the lactose content of the milk and decreased the somatic cell count of multiparous cows. The listed parameters were not significant (P<0.05 compare to the results of positive control groups. The applied live yeast culture supplementation did not significant affect for other performance of the cows.

    Full Text Available Abstract Background Intermittent fasting (IF improves healthy lifespan in animals by a mechanism involving reduced oxidative damage and increased resistance to stress. However, no studies have evaluated the impact of controlled meal frequency on immune responses in human subjects. Objective A study was conducted to establish the effects of controlled diets with different meal frequencies, but similar daily energy intakes, on cytokine production in healthy male and female subjects. Design In a crossover study design with an intervening washout period, healthy normal weight middle-age male and female subjects (n = 15 were maintained for 2 months on controlled on-site one meal per day (OMD or three meals per day (TMD isocaloric diets. Serum samples and peripheral blood mononuclear cells (PBMCs culture supernatants from subjects were analyzed for the presence of inflammatory markers using a multiplex assay. Results There were no significant differences in the inflammatory markers in the serum of subjects on the OMD or TMD diets. There was an increase in the capacity of PBMCs to produce cytokines in subjects during the first month on the OMD or TMD diets. Lower levels of TNF-α, IL-17, MCP-1 and MIP-1β were produced by PBMCs from subjects on the OMD versus TMD diet. Conclusions PBMCs of subjects on controlled diets exhibit hypersensitivities to cellular stimulation suggesting that stress associated with altered eating behavior might affect cytokine production by immune cells upon stimulation. Moreover, stimulated PBMCs derived from healthy individuals on a reduced meal frequency diet respond with a reduced capability to produce cytokines.

    Full Text Available Objectives : The aims of this study were to develop reportable event codes that are applicable to the national hemovigilance systems for hospital blood banks, and to present expansion strategies for the blood banks. Materials and Methods : The data were obtained from a literature review and expert consultation, followed by adding to and revising the established hemovigilance code system and guidelines to develop reportable event codes for hospital blood banks. The Medical Error Reporting System-Transfusion Medicine developed in the US and other codes of reportable events were added to the Korean version of the Biologic Products Deviation Report (BPDR developed by the Korean Red Cross Blood Safety Administration, then using these codes, mapping work was conducted. We deduced outcomes suitable for practice, referred to the results of the advisory councils, and conducted a survey with experts and blood banks practitioners. Results : We developed reportable event codes that were applicable to hospital blood banks and could cover blood safety - from blood product safety to blood transfusion safety - and also presented expansion strategies for hospital blood banks. Conclusion : It was necessary to add 10 major categories to the blood transfusion safety stage and 97 reportable event codes to the blood safety stage. Contextualized solutions were presented on 9 categories of expansion strategies of hemovigilance system for the hospital blood banks.

    We investigated the association of plasma AGE (advanced glycation end product) concentration with central and peripheral blood pressures and central-to-brachial blood pressure amplification in a Chinese population. The study subjects were from a newly established residential area in the suburb of Shanghai. Using the SphygmoCor system, we recorded radial arterial waveforms and derived aortic waveforms by a generalized transfer function and central systolic and pulse pressure by calibration for brachial blood pressure measured with an oscillometric device. The central-to-brachial pressure amplification was expressed as the central-to-brachial systolic blood pressure difference and pulse pressure difference and ratio. Plasma AGE concentration was measured by the enzyme-linked immunosorbent assay method and logarithmically transformed for statistical analysis. The 1051 participants (age, 55.1±13.1 years) included 663 women. After adjustment for sex, age and other confounding factors, plasma AGE concentration was associated with central but not peripheral blood pressures and with some of the pressure amplification indexes. Indeed, each 10-fold increase in plasma AGE concentration was associated with 2.94 mm Hg (P=0.04) higher central systolic blood pressure and 2.39% lower central-to-brachial pulse pressure ratio (P=0.03). In further subgroup analyses, the association was more prominent in the presence of hypercholesterolemia (+8.11 mm Hg, P=0.008) for central systolic blood pressure and in the presence of overweight and obesity (-4.89%, P=0.009), diabetes and prediabetes (-6.26%, P=0.10) or current smoking (-6.68%, P=0.045) for central-to-brachial pulse pressure ratio. In conclusion, plasma AGE concentration is independently associated with central systolic blood pressure and pulse pressure amplification, especially in the presence of several modifiable cardiovascular risk factors.

    Clinicians sometimes are confronted with the challenge of transfusing haemorrhaging Rhesus (Rh) D negative patients with Rh D positive blood to save their lives. There are concerns about alloimmunization and future haemolytic disease of the newborn in women of the reproductive age. Another fear is transfusion reaction if they receive another Rh D positive blood in future. We present a 32-year-old Rh D negative woman, who had postpartum haemorrhage in her first pregnancy and was transfused with Rh D positive blood because of unavailability of Rh D negative blood. She did not receive anti D immunoglobin but subsequently had a normal term pregnancy of an Rh positive fetus without any detectable anti D antibodies throughout the pregnancy. In life threatening situations from obstetric haemorrhage, transfusion of Rh D negative women with Rh D positive blood should be considered as the last resort. PMID:26339087

    Montelukast is a highly selective leukotriene-receptor antagonist (LTRA). It is widely used in the treatment of bronchial asthma, primarily as an adjunct to corticosteroids. Reactive oxygen species (ROSs) play an important role in the pathogenesis of asthma and oxidative stress contributing to the initiation and worsening of inflammatory respiratory disorders, such as asthma. Antioxidant drugs may have a role in minimizing or preventing damage in asthmatic children. The aim of this study was to assess the antioxidant effect of montelukast on the production of free radicals in the whole blood and polymorphonuclear neutrophils (PMNs) in asthmatic children. A group of 48 (38 males and 10 females), apparently healthy asthmatic children were recruited with ages ranging between 6 and 14 years. In asthmatic children, base line (premedication) and post medication free radicals activity in the whole blood and polymorphonuclear neutrophils (PMNs) was determined by measuring chemiluminescence (CL) response through chemiluminescence luminometer. Free radical productions were significantly decreased in the whole blood, when stimulated with Phorbol Myristate Acetate (p < 0.04) and Opsonised Zymosan (p < 0.05). The free radicals were also significantly decreased in isolated polymorphonuclear neutrophils (PMNs) when stimulated with Opsonised Zymosan (p < 0.05) after the post medication treatment of montelukast in asthmatic children. Montelukast decreased the reactive oxygen species production, both in the whole blood as well as isolated PMNs in asthmatic children. PMID:23960762

    Full Text Available The aim of this study was to assess effects of the eight-week course of atorvastatin therapy upon the levels of spontaneous cytokine production by mononuclear blood leukocytes (MNBC in metabolic syndrome. An open-label prospective study included 36 patients with stage II hypertension (blood pressure < 180/110 mm Hg. accomplished by metabolic syndrome. Along with clinical surveys performed at a specialized cardiological clinics, we assessed spontaneous cytokine production by MNBC during treatment with atorvastatin. It was shown that the 8-week treatment of these patients with atorvaststin, at individually matched daily doses (20to 40 mg was associated with reduced serum concentration of acute phase proteins (C-reactive protein and neopterin, as well as decreased spontaneous production of proinflammatory cytokines (IL-1β, IL-6 and TNFα by MNBCs. The latter finding is of great importance for pathogenesis of metabolic syndrome.

    International Nuclear Information System (INIS)

    In the work authors inform results on studying influence of a productive solution of uranium on some biochemical parameters of blood of an organism at experimental animals. It is established that all samples of a productive solution of uranium possesses high toxicity and causes destruction of experimental animals with infringement of a picture of blood. Experiments on influence on biochemical and hematology defined parameters of blood on chickens - broilers and on which female quails from daily age raised on cellular batteries in communities on 50 heads in conditions adequate to the requirement. Fed in plenty with the dry forages prepared according to 'Recommendations on the normalized feeding an agricultural bird' (1996), recipes 5-2; 6-1. To chickens in plenty allowed water from auto drinking bowls. Conditions of a micro climate corresponded to hygienic requirements. At carrying out of experiences studied the following parameters: preservation of a livestock, the reason of a withdrawal, weight of a body - weekly up to the end of experience, consumption of a forage, an expense of a forage for 1 kg of a gain have established weight of a body the methods standard in poultry farming. After application of a productive solution took blood from under wings of a vein and in blood have established maintenance of hemoglobin, quantity of red cells, leukocytes and a leukocyte of the formula, the maintenance of calcium and phosphorus. An application of a productive solution for experimental birds for the fifth day has caused clinical symptoms of a poisoning and destruction in groups. At the survived birds in blood it has been established changes biochemical and hematology. Week age chickens of skilled group lagged behind in growth development in comparison with control group on 30 % and at the end of the skilled period skilled have lagged behind in growth and development on 62 %. Among a livestock of chickens of skilled group of a case was more on 53 % on comparisons with the

    The availability of an adequate blood supply is a critical public health need. An influenza epidemic or another crisis affecting population mobility could create a critical donor shortage, which could profoundly impact blood availability. We developed a simulation model for the blood supply environment in the United States to assess the likely impact on blood availability of factors such as an epidemic. We developed a simulator of a multi-state model with transitions among states. Weekly numbers of blood units donated and needed were generated by negative binomial stochastic processes. The simulator allows exploration of the blood system under certain conditions of supply and demand rates, and can be used for planning purposes to prepare for sudden changes in the public's health. The simulator incorporates three donor groups (first-time, sporadic, and regular), immigration and emigration, deferral period, and adjustment factors for recruitment. We illustrate possible uses of the simulator by specifying input values for an -week flu epidemic, resulting in a moderate supply shock and demand spike (for example, from postponed elective surgeries), and different recruitment strategies. The input values are based in part on data from a regional blood center of the American Red Cross during –. Our results from these scenarios suggest that the key to alleviating deficit effects of a system shock may be appropriate timing and duration of recruitment efforts, in turn depending critically on anticipating shocks and rapidly implementing recruitment efforts.

    Full Text Available Umbilical cord blood (UCB is considered to be a source of hematopoietic stem cells (HSCs. All UCB banks have recently become interested in the isolation and storage of HSCs for the treatment of hematological diseases. However, UCB was also recently confirmed as a source of immune cells for immunotherapy such as dendritic cells (DCs and cytokine-induced killer cells (CIKs. This study aimed to exploit this source of immune cells in banked UCB samples. After collection of UCB samples, mononuclear cells (MNCs containing stem cells, progenitor cells, and mature cells were isolated by Ficoll-Hypaque-based centrifugation. The MNCs were subjected to freezing and thawing according to a previously published protocol. The banked MNCs were used to produce DCs and CIKs. To produce DCs, MNCs were induced in RPMI 1640 medium supplemented with GM-CSF (50 ng/ml and IL-4 (40 ng/ml for 14 days. To produce CIKs, MNCs were induced in RPMI 1640 medium supplemented an anti-CD3 monoclonal antibody, IL-3, and GMC-SF for 21 and ndash;28 days. Both DCs and CIKs were evaluated for their phenotypes and functions according to previously published protocols. The results showed that banked UCB samples can be successfully used to produce functional DCs and CIKs. These samples are valuable sources of immune cells for immunotherapy. The present results suggest that banked UCB samples are useful not only for stem cell isolation, but also for immune cell production. [Biomed Res Ther 2015; 2(11.000: 402-408

    Anxin Wang

    Full Text Available OBJECTIVE: To investigate potential associations between resting heart rate, blood pressure and the product of both, and the brachial-ankle pulse wave velocity (baPWV as a maker of arterial stiffness. METHODS: The community-based "Asymptomatic Polyvascular Abnormalities in Community (APAC Study" examined asymptomatic polyvascular abnormalities in a general Chinese population and included participants with an age of 40+ years without history of stroke and coronary heart disease. Arterial stiffness was defined as baPWV≥1400 cm/s. We measured and calculated the product of resting heart rate and systolic blood pressure (RHR-SBP and the product of resting heart rate and mean arterial pressure (RHR-MAP. RESULTS: The study included 5153 participants with a mean age of 55.1 ± 11.8 years. Mean baPWV was 1586 ± 400 cm/s. Significant (P<0.0001 linear relationships were found between higher baPWV and higher resting heart rate or higher arterial blood pressure, with the highest baPWV observed in individuals from the highest quartiles of resting heart rate and blood pressure. After adjusting for confounding parameters such as age, sex, educational level, body mass index, fasting blood concentrations of glucose, blood lipids and high-sensitive C-reactive protein, smoking status and alcohol consumption, prevalence of arterial stiffness increased significantly (P<0.0001 with increasing RHR-SBP quartile (Odds Ratio (OR: 2.72;95%Confidence interval (CI:1.46,5.08 and increasing RHR-MAP (OR:2.10;95%CI:1.18,3.72. Similar results were obtained in multivariate linear regression analyses with baPWV as continuous variable. CONCLUSIONS: Higher baPWV as a marker of arterial stiffness was associated with a higher product of RHR-SBP and RHR-MAP in multivariate analysis. In addition to other vascular risk factors, higher resting heart rate in combination with higher blood pressure are risk factors for arterial stiffness.

    Interaction peculiarities of three components of the immune human homeostasis-antigens of blood groups AB0, staphylococcus antigens and antistaphylococcus antibodies have been investigated. Donors (85) of antistaphylococcus plasma immunized by staphylococcus anatoxin have been investigated. It is found that the nasal staphylococcus carriage in donors depends on the level of specific and natural antibodies and on the coincidence between the staphylococcus antigen structure and the protein substance of the specific blood group factors.

    OBJECTIVE: To compare the effects of aprotinin on blood product use and postoperative complications in patients undergoing thoracic aortic surgery requiring deep hypothermic circulatory arrest. DESIGN: A retrospective study. SETTING: A university hospital. PARTICIPANTS: Nineteen patients who underwent elective or urgent thoracic aortic surgery. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The total number of units of packed red blood cells, fresh frozen plasma, and platelets was significantly less in the group that received aprotinin (p = 0.01, 0.04, and 0.01). The intraoperative transfusion of packed red blood cells and platelets, collection and retransfusion of cell saver, and postoperative transfusion of fresh frozen plasma were also significantly less in the aprotinin group (p = 0.01, 0.02, 0.01, and 0.05). No patient in either group sustained renal dysfunction or a myocardial infarction. Two patients who had not received aprotinin suffered from chronic postoperative seizures, and one patient who had received aprotinin sustained a perioperative stroke. CONCLUSIONS: Low-dose aprotinin administration significantly decreases blood product transfusion requirements in the setting of thoracic aortic surgery requiring deep hypothermic circulatory arrest, and it does not appear to be associated with renal or myocardial dysfunction.

  15. Blood Products and the Commodification Debate: The Blurry Concept of Altruism and the 'Implicit Price' of Readily Available Body Parts.

    Science.gov (United States)

    Dufner, Annette

    2015-12-01

    There is a widespread consensus that a commodification of body parts is to be prevented. Numerous policy papers by international organizations extend this view to the blood supply and recommend a system of uncompensated volunteers in this area--often, however, without making the arguments for this view explicit. This situation seems to indicate that a relevant source of justified worry or unease about the blood supply system has to do with the issue of commodification. As a result, the current health minister of Ontario is proposing a ban on compensation even for blood plasma--despite the fact that Canada can only generate 30 % of the plasma needed for fractionation into important plasma protein products and has to purchase the rest abroad. In the following, I am going to suggest a number of alternative perspectives on the debate in order to facilitate a less dogmatic and more differentiated debate about the matter. Especially in light of the often over-simplified notions of altruism and commodification, I conclude that the debate has not conclusively established that it would be morally objectionable to provide blood plasma donors with monetary compensation or with other forms of explicit social recognition as an incentive. This is especially true of donations for fractionation into medicinal products by profit-oriented pharmaceutical companies. PMID:25471706

    Aim: To elucidate the mechanisms underlying homocysteine (Hcy)-induced chemokine production. Methods: Human whole blood was pretreated with inhibitors of calmodulin (CaM), protein kinase C (PKC), protein tyrosine kinase(PTK), mitogen-activated protein kinase (MAPK), and NF-κB and activators of PPARγ for 60 min followed by incubation with Hcy 100 μmol/L for 32 h. The levels of mitogen chemokine protein (MCP)-1 and interleukin-8 (IL-8) were determined by enzyme-linked immunosorbant assay (ELISA). Results: Inhibitors of PKC (calphostin C, 50-500 nmol/L and RO-31-8220, 10-100 nmol/L), CaM(W7, 28-280 μmol/L), ERK1/2 MAPK (PD 98059, 2-20 μmol/L), p38 MAPK(SB 203580, 0.6-6 μmol/L), JNK MAPK (curcumin, 2-10 μmol/L), and NF-κB(PDTC, 10-100 nmol/L) markedly reduced Hcy 100 μmol/L-induced production of MCP-1 and IL-8 in human cultured whole blood, but the inhibitors of PTK(genistein, 2.6-26 μmol/L and tyrphostin, 0.5-5 μmol/L) had no obvious effect on MCP-1 and IL-8 production. PPARγ activators (ciglitazone 30 μmol/L and troglitazone 10 μmol/L) depressed the Hcy-induced MCP-1 production but not IL-8 production in the cultured whole blood. Conclusion: Hcy-induced MCP-1 and IL-8 production is mediated by activated signaling pathways such as PKC,CaM, MAPK, and NF-κB. Our results not only provide clues for the signal transduction pathways mediating Hcy-induced chemokine production, but also offer a plausible explanation for a pathogenic role of hyperhomocysteinemia in these diseases.

    We have determined estimates for 24 physiological parameters of production, interpool transport, distribution, and metabolism of T3 in the major T3 pools of the unanesthetized male Sprague-Dawley rat, from blood-borne data and a comprehensive model and analysis of this system. Most of these indices have previously been unavailable. Whereas only 3% (2 ng/100 g BW) of the total body T3 pool (74 ng/100 g BW) is in plasma, the composite of slowly equilibrating (slow) tissue pools (e.g. muscle, skin, and brain) appears to contain most of the T3, 76% (57 ng/100 g BW) of the total. The composite of rapidly equilibrating (fast) tissue pools (e.g. liver and kidney) contains the remaining 19% (16 ng/100 g BW). The total body T3 production rate is 0.12 ng/100 g BW . min, and we estimate that about half of this emanates directly from T4 in the slow pools, whereas the remainder is derived from both thyroidal secretion and T4 to T3 conversion in the fast pools. Our results also indicate that T3 molecules spend an average of only 0.5 min in transit each time through plasma, whereas the single pass mean transit times in fast and slow tissue pools (the times available for hormone action) are 10 times and 200 times greater. In contrast, the mean residence time for T3 in the entire system is greater than 12 h despite the extremely rapid early disappearance of injected T3 from plasma. To obtain the required accuracy, we used a novel optimization approach for choosing blood-sampling schedules (1, 4, 44, 202, and 600 min), a remarkably small number of sample times, and each was adjustable by about +/- 20% without effect on optimized parameter accuracies.

    The chemical composition of spray dried porcine blood by-products is characterised by wide variation in crude protein contents. In spray dried porcine blood plasma (SDBP) it varied between 670-780 g/kg, in spray dried blood cells (SDBC) between 830-930 g/kg, and in bone protein hydrolysate (BPH) in a range of 740-780 g/kg. Compared with fish meal, these feeds are poor in Met and Lys. Moreover, in BPH deep deficits of Met, Cys, Thr and other amino acids were found. The experiment comprised 7 dietary treatments: SDBP, SDBC, and BPH, each at an inclusion rate of 20 or 40 g/kg diet, plus a control. The addition of 20 or 40 g/kg of the analysed meals into feeds for very young chickens (1-28 d post hatch) significantly decreased the body weight (BW) of birds. Only the treatments with 40 g/kg of SDBP and SDBC showed no significant difference in BW as compared with the control. There were no significant differences between treatments and type of meal for feed intake, haematocrit and haemoglobin concentrations in blood. Addition of bone protein and blood cell meals to feed decreased the IgG concentration in blood and caused shortening of the femur and tibia bones. However, changes in the mineral composition of bones were not significantly affected by the type of meal used. The blood by-products, which are rich in microelements, improved retention of Ca and Cu only. In comparison to control chickens, significantly better accretion of these minerals was found in treatments containing 20 g/kg of SDBP or 40 g/kg of SDBC. Great variability in apparent ileal amino acid digestibility in chickens was determined. In this respect, some significant differences related to the type of meal fed were confirmed for Asp, Pro, Val, Tyr and His. In general, the apparent ileal digestibility of amino acids was about 2-3 percentage units better in chickens fed on diets containing the animal by products than in control birds. PMID:22029787

    Full Text Available Angiocardiography is an X-ray examination of the blood vessels or chambers of the heart. Cardiologists and staff members applying this procedure are exposed to high levels of scattered radiation. In our previous study the incidence of unstable chromosomal aberrations and cytokinesis-blocked micronuclei were found to be significantly higher in exposed individuals than the age and sex matched controls. In the present study we assessed cytokine production by peripheral blood mononuclear cells of the above cases and the percentage of Treg cells. According to film dosimeter analysis, personnels received 0.25-15 mSv during the previous year (average of 3 mSv/y. Isolated PBMCs from the test and control groups were stimulated with Phorbol Myristate Acetate/ Ionomycin (PMA/I. Cytokine production was measured in the supernatants of cultured lymphocytes. The percentage of Treg cells was studied by flow cytometry. The production of IL-10 and IL-5 was significantly down-regulated in the test group compared to the control group. In contrast, IL-12 was up-regulated. Yet, no statistically significant difference was found for IFN- γ between two groups. In addition, we found higher percentage of CD4+CD25+bright Treg cells in the study group compared to the controls. Taken together, it was shown that low doses of scattered X-rays could skew cytokine profile of peripheral blood mononuclear cells in favour of inflammatory response causing the increase of Treg cells.

    The present study was aimed to evaluate the cadmium (Cd) and lead (Pb) levels in the blood samples of adolescent boys, chewing different smokeless tobacco (SLT) products in Pakistan. For comparative purpose, boys of the same age group (12-15 years), not consumed any SLT products were selected as referents. To determine trace levels of Cd and Pb in blood samples, a preconcentration method, vortex-assisted liquid-liquid microextraction (VLLME) has been developed, prior to analysis by flame atomic absorption spectrometry. The hydrophobic chelates of Cd and Pb with ammonium pyrrolidinedithiocarbamate were extracted into the fine droplets of ionic liquid (IL) 1-butyl-3-methylimidazolium hexafluorophosphate, while nonionic surfactant, Triton X-114 was used as a dispersing medium. The main factors affecting the recoveries of Cd and Pb, such as concentration of APDC, centrifugation time, volume of IL and TX-114, were investigated in detail. It was also observed that adolescent boys who consumed different SLT products have 2- to 3-fold higher levels of Cd and Pb in their blood samples as compared to referent boys (p < 0.001).

    Full Text Available Abstract Background It has been proposed that outer surface protein A (OspA of Borrelia burgdorferi sensu stricto contains a T helper 1 (Th1 cell epitope that could play a role in an autoimmune response to hLFA1. Methods We used two peptides, hLFAαL (aa326-345 and Borrelia burgdorferi OspAB31 (aa164-183, as stimulating antigens to measure Th1 proinflammatory IFNγ cytokine production in peripheral blood of Lyme disease patients presenting with EM without history of arthritis, as well as in peripheral blood of healthy individuals. Results IFNγ responses to hLFA1 peptide were observed in 11 of 19 Lyme disease patients and in 3 of 15 healthy controls. In contrast, only 2 of 19 of the Lyme disease patients and none of the controls responded to the homologous OspAB31 peptide. Conclusions IFNγ was produced in response to stimulation with peptide hLFAαL (aa326-345 in peripheral blood of 58% of patients with early Lyme disease without signs of arthritis, as well as in peripheral blood of 20% of healthy individuals, but not in response to stimulation with the homologous OspAB31 (aa164-183 peptide (p

    The experiment was designed to study the changes in some blood parameters and production performance of old laying hens after injection of different doses of growth hormone (GH) and testosterone (Ts). A total of 160 old laying hens (HyLine W-36) at 73 weeks of age were weighed individually and randomly allocated to four treatments with four replicates and 10 birds in each replicate in a completely randomized design. Growth hormone and Ts hormones were injected subcutaneously. Treatment groups were as follows: treatment 1: injection of 100 μl distiled water (control group), treatment 2: injection of 500 μg Ts/kg live-weight + 50 μgGH/kg live-weight, treatment 3: injection of 500 μgTs/kg live-weight + 100 μgGH/kg live-weight and treatment 4: injection of 500 μgTs/kg live-weight + 150 μgGH/kg live-weight. Plasma levels of oestradiol, T4 , LDL, HDL and cholesterol significantly increased in treatment 3 in relation to the control group. All injected hens showed significantly higher levels of glucose in relation to control group. The results showed the positive effects of GH and Ts administration on production performance and blood parameters which are associated with egg production potentiality and in turn may improve reproductivity (egg production) in old laying hens. The positive results of the study may be useful in animal selection and breeding programmes. PMID:23808354

  12. Thymus cells in myasthenia gravis selectively enhance production of anti-acetylcholine-receptor antibody by autologous blood lymphocytes

    International Nuclear Information System (INIS)

    We investigated the role of the thymus in 16 patients with myasthenia gravis without thymoma by studying the production of anti-acetylcholine-receptor antibody by thymic and blood lymphocytes cultured alone or together. In 10 responders (with the highest receptor-antibody titers in their plasma), cultured thymic cells spontaneously produced measurable receptor antibody. Receptor-antibody production by autologous blood lymphocytes was enhanced by the addition of responder's thymic cells, irradiated to abrogate antibody production and suppression (P<0.01). This enhancement was greater and more consistent than that by pokeweed mitogen; it depended on viable thymic cells, appeared to be selective for receptor antibody, and correlated with the ratio of thymic helper (OKT4-positive or OKT4+) to suppressor (OKT8+) T cells (P<0.01). These results suggest that myasthenic thymus contains cell-bound acetylcholine-receptor-like material or specific T cells (or both) that can aid receptor-antibody production. This may be relevant to the benefits of thymectomy in myasthenia and to the breakdown in self-tolerance in this and other autoimmune diseases

    Blood serum content was studied of specific antistaphylococcal antibodies (staphylolysins) in 576 donors immunized with staphylococcal anatoxin with the purpose of obtaining an antistaphylococcal plasma and antistaphylococcal immunoglobulin to be used in clinical settings. 292 donors had been immunized and examined prior to 1986, 284--after 1986 (before 1994). Comparison of the immune responses in the above periods of time permitted finding out that 13.03% of immunized donors responded to the antigenic stimulus by such paradoxical reaction as disappearance of specific antibodies; the number of persons-active respondents has gotten reduced from 17.12% to 5.98% as has the number of individuals having the baseline level of staphylolysins (1-2 ME/ml). The changes were at their greatest in donors with group A (II) blood. PMID:9621632

    This study aimed to evaluate the intake, digestion, blood parameters, and feeding behavior of crossbred dairy cows (Holstein × Gir) managed on Panicum maximum Jacq. cv. Tanzania-1 and provided supplementation with groundnut cake, sunflower cake, or palm kernel cake (to replace soybean meal). Sixteen cows were randomly assigned in a Latin square design with four treatments and four experimental periods. The consumption of nutrients from the pasture did not vary between experimental treatments. Cows receiving the palm kernel cake supplement had a reduced crude protein, non-fibrous carbohydrate, and total digestible nutrient intake and an increase in the average consumption of ether extract. There was also a reduction in the digestibility of dry matter. The inclusion of supplements in the diet did not influence the average time spent eating, ruminating, or resting. The mean values of respiratory and heart rates showed thermal comfort during the trial period. There was a reduction in blood urea nitrogen with palm kernel cake supplementation, and the values of total protein, albumin, and glucose were also significantly different with this supplement. It is recommended that cakes of groundnut cake and sunflower cake seed be used for a total replacement of soybean meal supplements for lactating cows, but the use of palm kernel cake is not recommended.

  7. Ex vivo measurement of calpain activation in human peripheral blood lymphocytes by detection of immunoreactive products of calpastatin degradation.

    Directory of Open Access Journals (Sweden)

    Jacek M Witkowski

    2008-01-01

    Full Text Available Limited proteolysis of multiple intracellular proteins by endogenous Ca-dependent cysteine proteases--calpains--is an important regulatory mechanism for cell proliferation, apoptosis etc. Its importance for cellular functions is stressed by existence of endogenous calpain inhibitors--calpastatins. The calpain-calpastatin system within living cells is in a fragile balance, which depends on both partners. The interdependence of calpain--a protease--and calpastatin--an endogenous inhibitor and at the same time a substrate for this enzyme makes any assessment of actual activity of this enzyme in the cells very difficult. In this work we made an attempt to estimate and compare the activity of calpain in human peripheral blood lymphocytes by assessing the levels of limited proteolysis of calpastatin in these cells by western blot, while at the same time the levels of calpain protein inside these cells was measured by flow cytometry. Our results indicate that it is possible to compare (semi-quantitatively the activities of calpain in peripheral blood CD4+ and CD19+ lymphocytes from various donors that way. Preliminary results showed that calpain activity is increased in the CD4+ T cells isolated from peripheral blood of rheumatoid arthritis patients as compared to control lymphocytes. Extremely high intrinsic activity of calpain was detected in chronic lymphocytic leukemia (CD19+ cells. All this confirms the detection of immunoreactive products of calpastatin as a good maker of endogenous calpain activity.

    AIM: To investigate the effects of Korea red ginseng (KRG) on the cerebral perfusion rate in the rats and the generation of superoxide anion in the endothelial cells. METHODS: The cerebral perfusion rate was measured using laser-doppler flowmetry before and after the administration of crude saponin (CS) and saponin-free fraction (SFF) of KRG in the anesthetized rats. The superoxide generation was measured by the method based on lucigeninenhanced chemiluminescence in the cultured endothelial cells. RESULTS: The relative cerebral perfusion rate (rCBF) was significantly increased by the intraperitoneal injection of CS (100 mg/kg) in the rats, but SFF had no effect on the rCBF. Chronic treatment with CS for 7 d significantly inhibited the decrease of forebrain cerebral blood flow induced by clamping both carotid arteries in the rats. Furthermore, CS (0.1 g/L) significantly suppressed NADPH-induced superoxide generation in the human umbilical vein endothelial cells (P<0.01).CONCLUSION: The present study demonstrated that crude saponin fraction of KRG enhanced cerebral blood flow in rats. Furthermore, crude saponin fraction of KRG abrogated the NADPH-driven superoxide generation in endothelial cells.

    Enhanced levels of platelet/granulocyte aggregates (PGAs) are found in patients suffering from many different inflammatory vascular diseases, and their formation in animal models of vascular disease is associated with increased thromboinflammation and worsened outcomes. The complement system, a part of the innate immune system, influences PGA formation, but the mechanisms for its effects are unknown. In this study, we have defined complement-mediated mechanisms that enhance PGA formation in human whole blood stimulated with thrombin receptor-activating peptide (TRAP) using ex vivo flow cytometry assays. We demonstrate that physiological properdin, a positive regulator of complement alternative pathway activity, increases PGA formation when added to TRAP-stimulated blood. All physiological properdin forms increase PGA formation, but properdin tetramers are the most efficient at increasing complement activity and PGA formation. Inhibition of endogenous properdin, either circulating in the blood or produced locally by leukocytes, impairs TRAP-mediated PGA formation to the same level as specific inhibition of either the alternative or classical pathway. Additionally, blocking the interaction of C5a with its cellular receptor prevents properdin-mediated increases in PGA formation. Adding either properdin tetramers or C5a to whole blood increases CD11b expression on granulocytes, and this increase is prevented by blockade of the C5a-C5a receptor axis. Finally, we demonstrate that the effects of properdin on PGA formation are tightly regulated by Factor H. Cumulatively, our data indicate that properdin enhances PGA formation via increased production of C5a, and that inhibition of properdin function has therapeutic potential to limit thromboinflammation in diseases characterized by increased PGA formation.

    Full Text Available INTRODUCTION: The innate immune response is the first mechanism of protection against Trypanosoma cruzi, and the interaction of inflammatory cells with parasite molecules may activate this response and modulate the adaptive immune system. This study aimed to analyze the levels of cytokines and chemokines synthesized by the whole blood cells (WBC and peripheral blood mononuclear cells (PBMC of individuals seronegative for Chagas disease after interaction with live T. cruzi trypomastigotes. METHODS: IL-12, IL-10, TNF-α, TGF-β, CCL-5, CCL-2, CCL-3, and CXCL-9 were measured by ELISA. Nitrite was determined by the Griess method. RESULTS: IL-10 was produced at high levels by WBC compared with PBMC, even after incubation with live trypomastigotes. Production of TNF-α by both PBMC and WBC was significantly higher after stimulation with trypomastigotes. Only PBMC produced significantly higher levels of IL-12 after parasite stimulation. Stimulation of cultures with trypomastigotes induced an increase of CXCL-9 levels produced by WBC. Nitrite levels produced by PBMC increased after the addition of parasites to the culture. CONCLUSIONS: Surface molecules of T. cruzi may induce the production of cytokines and chemokines by cells of the innate immune system through the activation of specific receptors not evaluated in this experiment. The ability to induce IL-12 and TNF-α contributes to shift the adaptive response towards a Th1 profile.

    Rh-related transcripts present in bone marrow samples from several species of nonhuman primates (chimpanzee, gorilla, gibbon, crab-eating macaque) have been amplified by RT-polymerase chain reaction using primers deduced from the sequence of human RH genes. Nucleotide sequence analysis of the nonhuman transcripts revealed a high degree of similarity to human blood group Rh sequences, suggesting a great conservation of the RH genes throughout evolution. Full-length transcripts, potentially encoding 417 amino acid long proteins homologous to Rh polypeptides, were characterized, as well as mRNA isoforms which harbored nucleotide deletions or insertions and potentially encode truncated proteins. Proteins of 30-40,000 M{sub r}, immunologically related to human Rh proteins, were detected by western blot analysis with antipeptide antibodies, indicating that Rh-like transcripts are translated into membrane proteins. Comparison of human and nonhuman protein sequences was pivotal in clarifying the molecular basis of the blood group C/c polymorphism, showing that only the Pro103Ser substitution was correlated with C/c polymorphism. In addition, it was shown that a proline residue at position 102 was critical in the expression of C and c epitopes, most likely by providing an appropriate conformation of Rh polypeptides. From these data a phylogenetic reconstruction of the RH locus evolution has been calculated from which an unrooted phylogenetic tree could be proposed, indicating that African ape Rh-like genes would be closer to the human RhD gene than to the human RhCE gene. 55 refs., 4 figs., 1 tab.

    International Nuclear Information System (INIS)

    Conditions for large scale production of monoclonal antibodies (monoAB) on mice hybrids were determined: irradiation dose, amount of introduced hybridoma cells, possible substitution of imported pristane for Soviet-produced vaseline oil or a mixture thereof. DMSO did not exert toxic action neither on the cell itself, nor on the development of ascytic tumor in mice after thawing of cryopreserved cells. This enabled to abstain from washing of DMSO off the introduced cells. A simple method for enhancing the monoAB yield - acquisition of the washing-out solution for increased efficiency of large scale production - was developed and tested

    The following commentary was developed by the National Marrow Donor Program Cord Blood Advisory Group and is intended to provide an overview of umbilical cord blood (UCB) processing, summarize the current state of potency assays used to characterize UCB, and define limitations of the assays and future needs of the cord blood banking and transplant community. The UCB banking industry is eager to participate in the development of standardized assays to uniformly characterize cellular therapy products that are manufactured in a variety of ways. This paper describes the desired qualities of these assays and how the industry proposes to co-operate with developers to bring relevant assays to market. To that end, the National Marrow Donor Program (NMDP) Cord Blood Bank Network is available to serve as a resource for UCB testing material, research and development consulting, and product/assay testing in an accredited UCB manufacturing environment.

  4. Production and properties of monoclonal antibodies to human blood coagulation factor VII and factor VIIa

    International Nuclear Information System (INIS)

    Human factor VII is a trace vitamin K-dependent protein that circulates in blood as a single-chain precursor to a serine protease. Upon activation, two-chain factor VIIa activates factor x in the presence of tissue factor and calcium. Purified preparations of single-chain (SC) human factor VII and two-chain (TC) factor VIIa were utilized to immunize Balb/c mice. Spleen cells from these immunized mice were fused to a non-secreting NS-1 derivative of X63-Ag8 myeloma cells and grown in selective medium. Analysis of culture supernatants by EIA revealed several hybridomas that were secreting IgG specific for Sc-factor VII and TC-factor VIIa. In addition, several hybridomas secreted IgG that reacted equally well with factor VII and factor VIIa. One of the latter McAb (A-29) reacted with the heavy chain of factor VIIa and the intact factor VII molecule equally as judged by Western blotting. A-29 was produced in ascites fluid, purified and coupled to activated CH-Sepharose. Application of one liter of normal human plasma to 10 ml of this immunoadsorbent column, elution of factor VII and subsequent Western blot using 125I-rabbit anti-human factor VII indicated a single species of factor VII(M/sub r/ = 50 KDa) in normal plasma. These specific factor VII/VIIa McAbs may prove useful in the analysis of these factors, and in the separation of SC-factor VII from TC-factor VIIa

    Full Text Available Abstract Background Inadequate surgical hemostasis may lead to transfusion and/or other bleeding-related complications. This study examines the incidence and costs of bleeding-related complications and/or blood product transfusions occurring as a consequence of surgery in various inpatient surgical cohorts. Methods A retrospective analysis was conducted using Premier's Perspective™ hospital database. Patients who had an inpatient procedure within a specialty of interest (cardiac, vascular, non-cardiac thoracic, solid organ, general, reproductive organ, knee/hip replacement, or spinal surgery during 2006-2007 were identified. For each specialty, the rate of bleeding-related complications (including bleeding event, intervention to control for bleeding, and blood product transfusions was examined, and hospital costs and length of stay (LOS were compared between surgeries with and without bleeding-related complications. Incremental costs and ratios of average total hospital costs for patients with bleeding-related complications vs. those without complications were estimated using ordinary least squares (OLS regression, adjusting for demographics, hospital characteristics, and other baseline characteristics. Models using generalized estimating equations (GEE were also used to measure the impact of bleeding-related complications on costs while accounting for the effects related to the clustering of patients receiving care from the same hospitals. Results A total of 103,829 cardiac, 216,199 vascular, 142,562 non-cardiac thoracic, 45,687 solid organ, 362,512 general, 384,132 reproductive organ, 246,815 knee/hip replacement, and 107,187 spinal surgeries were identified. Overall, the rate of bleeding-related complications was 29.9% and ranged from 7.5% to 47.4% for reproductive organ and cardiac, respectively. Overall, incremental LOS associated with bleeding-related complications or transfusions (unadjusted for covariates was 6.0 days and ranged from 1

    Full Text Available GSH (γ-glutamylcysteinylglycine is a sulfhydril (-SH antioxidant, antitoxin and enzyme cofactor which is an important component of the cellular detoxification of reactive oxygen species (ROS. Being water soluble it is found mainly in the cytosol and other aqueous phases of the living system and thus constitute one of the most important intracellular antioxidants (10,7,9. GSH plays a role in removing various toxic chemicals and drugs from the body. As a result glutathione levels in the body are reduced by exposure to heavy metals and the chemicals used in chemotherapy (6. Sulfanilamide was the first sulfonamide discovered in this class of antimicrobial agents and its structure is considered to contain the minimum pharmacophore. They prevent or limit bacterial multiplication. Salicylic acid (2-hydroxybenzoic acid, is the basic substance of the salicylates which are non-steroidal anti-inflammatory drugs (NSAIDs. Salicylic acid and methyl salicylate (ester (methyl 2-hydroxybenzoate are the main therapeutically used substances of this group. This study was carried out to investigate the effect of a new synthesis product in comparison with the effect of sulfanilamide on GSH values in intraperitonally injected Wistar rats.

    Intravesical administration of bacillus Calmette-Guérin (BCG) is an effective and widely accepted treatment for superficial bladder cancer. Rapid progression of the disease after BCG therapy, however, has been reported in some cases refractory to the treatment. We examined whether BCG treatment and coexistence of peripheral blood mononuclear cells (PBMCs) alter the invasive potential of bladder cancer cells. Production and secretion of two type IV collagenases, matrix metalloproteinase (MMP) 2 and MMP 9, by PBMCs from five healthy donors or bladder cancer cells (T24, JTC 30, and JTC 32) were evaluated by gelatin zymography, western blot analysis, and northern blot analysis. Invasion of bladder cancer cells was also examined using reconstituted basement membrane (Matrigel). BCG (5, 50, and 500 micrograms/ml) had no effect on secretion of MMP 2 and MMP 9 by bladder cancer cells, but increased the production and secretion of MMP 9 by PBMCs in a dose-dependent manner. The coexistence of PBMCs increased invasion of T24 cells and BCG further enhanced the invasion. Thus, BCG promotes invasion of bladder cancer cells under certain conditions. An increase in the secretion of MMP 9 by PBMCs may account in part for the effect. PMID:9140113

  20. Efficient removal of platelets from peripheral blood progenitor cell products using a novel micro-chip based acoustophoretic platform.

    Directory of Open Access Journals (Sweden)

    Josefina Dykes

    Full Text Available BACKGROUND: Excessive collection of platelets is an unwanted side effect in current centrifugation-based peripheral blood progenitor cell (PBPC apheresis. We investigated a novel microchip-based acoustophoresis technique, utilizing ultrasonic standing wave forces for the removal of platelets from PBPC products. By applying an acoustic standing wave field onto a continuously flowing cell suspension in a micro channel, cells can be separated from the surrounding media depending on their physical properties. STUDY DESIGN AND METHODS: PBPC samples were obtained from patients (n = 15 and healthy donors (n = 6 and sorted on an acoustophoresis-chip. The acoustic force was set to separate leukocytes from platelets into a target fraction and a waste fraction, respectively. The PBPC samples, the target and the waste fractions were analysed for cell recovery, purity and functionality. RESULTS: The median separation efficiency of leukocytes to the target fraction was 98% whereas platelets were effectively depleted by 89%. PBPC samples and corresponding target fractions were similar in the percentage of CD34+ hematopoetic progenitor/stem cells as well as leukocyte/lymphocyte subset distributions. Median viability was 98%, 98% and 97% in the PBPC samples, the target and the waste fractions, respectively. Results from hematopoietic progenitor cell assays indicated a preserved colony-forming ability post-sorting. Evaluation of platelet activation by P-selectin (CD62P expression revealed a significant increase of CD62P+ platelets in the target (19% and waste fractions (20%, respectively, compared to the PBPC input samples (9%. However, activation was lower when compared to stored blood bank platelet concentrates (48%. CONCLUSION: Acoustophoresis can be utilized to efficiently deplete PBPC samples of platelets, whilst preserving the target stem/progenitor cell and leukocyte cell populations, cell viability and progenitor cell colony-forming ability

  1. Cerebral extraction of N-13 ammonia: its dependence on cerebral blood flow and capillary permeability, surface area product

    International Nuclear Information System (INIS)

    13N-labeled ammonia was used to investigate: (1) the cerebral extraction and clearance of ammonia; (2) the mechanicsm by which capillaries accommodate changes in cerebral blood flow (CBF); and (3) its use for the measure of CBF. This was investigated by measuring the single pass extraction of 13NH3 in rhesus monkeys during P/sub a/CO2 induced changes in CBF, and with dog studies using in vitro tissue counting techniques to examine 13NH3 extraction in gray and white matter, mixed tissue, and cerebellum during variations in CBF produced by combinations of embolization, local brain compression, and changes in P/sub a/CO2. The single pass extraction fraction of 13NH3 varied from about 70 to 20% over a CBF range of 12 to 140cc/min/100gms. Capillary permeability-surface area product (PS) estimates from this data and the dog experiments show PS increasing with CBF. The magnitude and rate of increase in PS with CBF was highest in gray matter > mixed tissue > white matter. Tissue extraction of 13NH3 vs CBF relationship was best described by a unidirectional transport model in which CBF increases by both recruitment of capillaries and by increases of blood velocity in open capillaries. Glutamine synthetase, which incorporates 13NH3 into glutamine, appears to be anatomically located in astrocytes in general and specifically in the astrocytic pericapillary end-feet that are in direct contact with gray and white matter capillaries. The net 13NH3 extraction subsequent to an i.v. injection increases nonlinearly with CBF. Doubling or halving basal CBF produced from 40 to 50% changes in the 13N tissue concentrations with further increases in CBF associated with progressively smaller changes in 13N concentrations. 13NH3 appears to be a good tracer for the detection of cerebral ischemia with positron tomography but exhibits a poor response at high values of CBF

    T follicular helper cells (Tfh) provide help to B cells to support their activation, expansion and differentiation. However, the role of Tfh cells in chronic HBV infection is poorly defined. The aim of this research was to examine the function of Tfh cells and whether they are involved in HBV related disease. Blood CXCR5+CD4+T cells and B cells in 85 patients with chronic HBV infection (HBV patients) and health controls (HC) were examined by flow cytometry. The molecule expression in blood CXCR5+CD4+ T cells was detected by real-time PCR. Blood CXCR5+CD4+ T cells and B cells were co-cultured and the production of Ig and cytokines was detected by ELISA. Autoantibodies were detected by indirect immunofluorescence and immunospot assay. We found that blood CXCR5+CD4+ T cells in patients with chronic HBV infection (HBV patients) expressed higher level of activation related molecules and cytokines than that from health controls (HC).In HBV patients, the frequency of blood CXCR5+CD4+ T cells was significantly correlated with serum ALT and AST. We also found that blood CXCR5+CD4+ T cells from HBV patients could induce B cells to secret higher level of immunoglobulin than that from HC. Several autoantibodies, including ANA, ss-A, ss-B, Scl-70, Jo-1, ect, were indeed positive in 65% HBV patients. Among HBV patients, expression of function related molecules was significantly higher in blood CXCR5+CD4+ T cells from patients with autoantibodies than that without autoantibodies. Our research indicated that blood CXCR5+CD4+ T cells from HBV patients were over activated and show augmented capacity to help B cells for antibody secreting, which might correlated with liver inflammation and the production of autoantibodies in extrahepatic manifestations.

    Full Text Available Background: In our previous study we found that rhsIL-6R, along with recombinant human interleukin-6, plays a regulatory role in the immune response by modulating the tumour necrosis factor-α (TNF-α expression and its production by peripheral blood mononuclearcells (PBMC. We also suggested that sIL-6R with IL-6 secreted by human PMN (neutrophils influenced the TNF-α expression and its production by autologous PBMC.

  9. Medroxyprogesterone acetate alters Mycobacterium bovis BCG-induced cytokine production in peripheral blood mononuclear cells of contraceptive users.

    Directory of Open Access Journals (Sweden)

    Léanie Kleynhans

    Full Text Available Most individuals latently infected with Mycobacterium tuberculosis (M.tb contain the infection by a balance of effector and regulatory immune responses. This balance can be influenced by steroid hormones such as glucocorticoids. The widely used contraceptive medroxyprogesterone acetate (MPA possesses glucocorticoid activity. We investigated the effect of this hormone on immune responses to BCG in household contacts of active TB patients. Multiplex bead array analysis revealed that MPA demonstrated both glucocorticoid and progestogenic properties at saturating and pharmacological concentrations in peripheral blood mononuclear cells (PBMCs and suppressed antigen specific cytokine production. Furthermore we showed that PBMCs from women using MPA produced significantly lower levels of IL-1α, IL-12p40, IL-10, IL-13 and G-CSF in response to BCG which corresponded with lower numbers of circulating monocytes observed in these women. Our research study is the first to show that MPA impacts on infections outside the genital tract due to a systemic effect on immune function. Therefore MPA use could alter susceptibility to TB, TB disease severity as well as change the efficacy of new BCG-based vaccines, especially prime-boost vaccine strategies which may be administered to adult or adolescent women in the future.

    2010-01-01

    The present experiment examined the effect of offering either a high- (H) or low- (L) energy-density diet in late gestation and early lactation on physiological parameters, body condition score (BCS) and milk production in early lactation. In all, 40 multiparous Holstein cows were randomly...... at calving (2.68 v. 2.34, P < 0.01). Energy corrected milk yield and energy-intake post-calving were not affected by pre-calving diets. Changes in BCS and blood concentrations of non-esterified fatty acids, beta-hydroxybutyrate and glucose in early lactation showed that cows offered diet H pre......-calving generally mobilised more body reserves compared to cows offered diet L pre-calving. An interaction between pre- and post-calving diets showed that cows offered diet H pre-calving had lower body tissue mobilisation when offered diet H post-calving compared to diet L. Cows offered diet L pre-calving, did not...

  11. Restoration of intracellular ATP production in banked red blood cells improves inducible ATP export and suppresses RBC-endothelial adhesion.

    Transfusion of banked red blood cells (RBCs) has been associated with poor cardiovascular outcomes. Storage-induced alterations in RBC glycolytic flux, attenuated ATP export, and microvascular adhesion of transfused RBCs in vivo could contribute, but the underlying mechanisms have not been tested. We tested the novel hypothesis that improving deoxygenation-induced metabolic flux and the associated intracellular ATP generation in stored RBCs (sRBCs) results in an increased extracellular ATP export and suppresses microvascular adhesion of RBCs to endothelium in vivo following transfusion. We show deficient intracellular ATP production and ATP export by human sRBCs during deoxygenation (impairments ~42% and 49%, respectively). sRBC pretreatment with a solution containing glycolytic intermediate/purine/phosphate precursors (i.e., "PIPA") restored deoxygenation-induced intracellular ATP production and promoted extracellular ATP export (improvement ~120% and 50%, respectively). In a nude mouse model of transfusion, adhesion of human RBCs to the microvasculature in vivo was examined. Only 2% of fresh RBCs (fRBCs) transfused adhered to the vascular wall, compared with 16% of sRBCs transfused. PIPA pretreatment of sRBCs significantly reduced adhesion to just 5%. In hypoxia, adhesion of sRBCs transfused was significantly augmented (up to 21%), but not following transfusion of fRBCs or PIPA-treated sRBCs (3.5% or 6%). Enhancing the capacity for deoxygenation-induced glycolytic flux within sRBCs increases their ability to generate intracellular ATP, improves the inducible export of extracellular anti-adhesive ATP, and consequently suppresses adhesion of stored, transfused RBCs to the vascular wall in vivo.

  12. The effect of peripheral blood lymphocyte stimulation on zeta chain expression and IL-2 production in Hodgkin's disease

    Frydecka, I; Boćko, D; Kosmaczewska, A; Ciszak, L; Morilla, R

    2001-01-01

    It has been reported that peripheral blood T cells and NK cells express reduced levels of the T-cell receptor signal-transducing zeta chain in Hodgkin's disease (HD). The zeta chain has emerged as a key subunit of the T-cell antigen receptor, which plays a central role in the signal-transducing events leading to T and NK-cell activation. We were interested in determining whether the low zeta chain expression in HD could be corrected by anti-CD3, anti-CD3-rIL-2 ex vivo stimulation. Zeta chain expression was analysed by dual immunofluorescence on permeabilized cells before and after 72 hours of culture. The IL-2 concentration in the culture supernatants was measured by ELISA. Zeta chain was significantly reduced on unstimulated CD4+, CD8+ and CD56+ cells from patients in active disease compared with normal subjects. In patients in complete remission, the values were normal except for CD8+ cells, on which zeta expression remained significantly reduced. Stimulation with anti-CD3 did not change zeta expression. Co-stimulation with rIL-2 increased but did not normalize the proportions of CD4+/zeta+, CD8+/zeta+and CD56+/zeta+cells and IL-2 production in active disease. Stimulation of cells from patients in clinical remission with anti-CD3+rIL-2 increased the proportion of CD8+zeta+cells and normalized IL-2 production levels. Considering the pivotal role of CD3-zeta in immune response, our data suggest that successful immunotherapy approaches in active HD should consider inclusion of other potent cytokines, as well as genetically engineered tumour vaccines. © 2001 Cancer Research Campaign www.bjcancer.com PMID:11355944

  3. Blood Component Therapy

    OpenAIRE

    Kelton, J. G.

    1984-01-01

    Human blood has been transfused for about 60-70 years. Over this time, the practice of blood transfusion has changed dramatically. One major change is the separation of blood into its various components. As a result, the patient can receive only the blood component in which he is deficient. In this way, the risk of side effects—particularly hepatitis—is lessened. This article briefly reviews the various blood products, the indications for their use, and some associated risks. These products i...

  4. The influence of X-radiation on production of interleukin-6 and alpha-tumor necrosis factor by perepheral blood mononuclears

    International Nuclear Information System (INIS)

    The influence of X-radiation on production of interleurin-6 (IL-6) and α-tumor necrosis factor (TNF) has been investigated. Irradiation with doses of 45, 90 and 900 cGy was shown to increase considerably TNF and IL-6 production both in intact mononuclear cultures of human peripheral blood and in cultures stimulated by phytohemagglutinin. In addition to an absolute increase in the production, the stimulatory effect was manifested by earlier accumulation of IL-6 and TNF activities in supernatant fractions of the cultures under study

  5. Effect of advanced glycosylation end products on activity of protein kinase C in human peripheral blood mononuclear cells

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Objectives TO investigate the effect of advanced glycosylation end products (AGEs) on the activity of protein kinese C (PKC) in human peripheral bloodmononuclear Cells (PBMC) and to observe whether aminoguanidine (AG) can influence the effect of AGEs. Methods After PBMC were isoiated from human peripheral blood and incubated with different concentrations of AGEs-BSA for various periods, total PKC activity in PBMC was determined by measuring the incorporation of 32P from [γ-32P] ATP=into a special substrate using Prornega PKC assay kit. Results AGEs-BSA increased the total PKC activity in PBMC from 83.43±6.57 pmol/min/mg protein to 116.8±13.82 pmol/min/mg protein with a peak at 15 min.AGEs-BSA also increased the total PKC activity in a concentration-dependent manner from 83.1±6.4 pmol/min/mg protein(control) to 119.1±13.3 pmol/min/mg protein (control vs AGEs-BSA 400 mg/L, P<0.01). Furthermore, AGEs-BSA induced an elevation of PKC activity in a glycosylating time-related manner,from 80.9±8.2 (control) to 118.3±11.5 pmol/min/mg protein (glycasytation for 12 wk, P<0.01). The total PKC activity stimulated by AGEs-BSA pretreated with AG (100, 200 mg/L) was markedly lower than that of AGEs-BSA group not pretreated with AG ( P<0.05, P<0.01). Conclusions AGEs-BSA increased the total PKC activity in PBMC in a concentration and incubation time dependent manner. The ability of AGEs-B.SA to stimulate PKC activity was markedly decreased by pretreatment of AGEs-BSA with AG.

  6. Productive performance and blood parameters of bulls fed diets containing babassu mesocarp bran and whole or ground corn

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The objective of the present study was to evaluate the effects of corn milling and the inclusion of babassu mesocarp bran (BMB on productive performance, digestibility of dietary nutrients, and blood parameters of dairy crossbred (Holstein-Gyr bulls finished in confinement. Twenty-four bulls were fed four different experimental diets, containing two levels of inclusion of BMB (0 and 41.24% and corn supplied in two different forms (ground and whole, for 98 days (77 days of data collection and 21 days of adaptation. The intakes and digestibility coefficients of the dry matter (DM and nutrients were determined. There were no significant interaction effects of the BMB inclusion level and the form of corn used on the performance and digestibility variables. The intakes of DM, crude protein (CP, and neutral detergent fibre (NDF increased with the inclusion of BMB in the diets. However, the inclusion of BMB in the diets decreased the ether extract intake, the NDF apparent digestibility, and the feed efficiency of DM and CP. Dry matter and NDF intakes also increased with the use of ground corn in the diet, which promoted an increase in the intake of total digestible nutrients (TDN, digestibility of non-fibrous carbohydrates, and average daily gain. However, the supply of ground corn reduced the feed efficiency of TDN. The remaining measured variables did not vary with the tested diets. The levels of plasma protein and albumin remained normal, but glucose concentrations were always high, irrespective of the tested diet. The form of corn supplied and the level of BMB inclusion had a significant interaction effect on the levels of triglycerides, urea, aspartate aminotransferase, and alkaline phosphatase. Babassu mesocarp bran can be included up to 41.24% in the diet of confined bulls without a negative effect on the animal weight gain. Corn should be supplied ground because this form improves the performance of crossbred bulls

  7. New insights into the effects on blood pressure of diets low in salt and high in fruits and vegetables and low-fat dairy products

    Directory of Open Access Journals (Sweden)

    Sacks Frank M

    2001-04-01

    Full Text Available Abstract Results from the recent Dietary Approaches to Stop Hypertension (DASH-Sodium trial provide the latest evidence concerning the effects of dietary patterns and sodium intake on blood pressure. Participants ate either the DASH diet (high in fruits, vegetables and low-fat dairy products, and reduced in saturated and total fat or a typical US diet. Within each diet arm, participants ate higher, intermediate, and lower sodium levels, each for 30 days. The results indicated lower blood pressure with lower sodium intake for both diet groups. Although some critics would argue otherwise, these findings provide important new evidence for the value of the DASH diet and sodium reduction in controlling blood pressure.

    Full Text Available Background: The goal of hemovigilance is to increase the safety and quality of blood transfusion. Identification of the adverse reactions will help in taking appropriate steps to reduce their incidence and make blood transfusion process as safe as possible. Aims : To determine the frequency and type of transfusion reactions (TRs occurring in patients, reported to the blood bank at our institute. Materials and Methods : A retrospective review of all TRs reported to the blood bank at the All India Institute of Medical Sciences, between December 2007 and April 2012 was done. All the TRs were evaluated in the blood bank and classified using standard definitions. Results: During the study period a total of 380,658 bloods and blood components were issued by our blood bank. Out of the total 196 adverse reactions reported under the hemovigilance system, the most common type of reaction observed was allergic 55.1% (n = 108, followed by febrile non-hemolytic transfusion reaction (FNHTR 35.7% (n = 70. Other less frequently observed reactions were Anaphylactoid reactions 5.1% (n = 10, Acute non-immune HTRs 2.6% (n = 5, Circulatory overload 0.5% (n = 1, Transfusion related acute lung injury 0.5% (n = 1, Delayed HTRs 0.5% (n = 1. Not a single case of bacterial contamination was observed. Conclusion: The frequency of TRs in our patients was found to be 0.05% (196 out of 380,658. This can be an underestimation of the true incidence because of under reporting. It should be the responsibility of the blood transfusion consultant to create awareness amongst their clinical counterpart about safe transfusion practices so that proper hemovigilance system can be achieved to provide better patient care.

    Chaves, A S; Nascimento, M L; Tullio, R R; Rosa, A N; Alencar, M M; Lanna, D P

    2015-10-01

    The objective of this study was to examine the relationship of efficiency indices with performance, heart rate, oxygen consumption, blood parameters, and estimated heat production (EHP) in Nellore steers. Eighteen steers were individually lot-fed diets of 2.7 Mcal ME/kg DM for 84 d. Estimated heat production was determined using oxygen pulse (OP) methodology, in which heart rate (HR) was monitored for 4 consecutive days. Oxygen pulse was obtained by simultaneously measuring HR and oxygen consumption during a 10- to 15-min period. Efficiency traits studied were feed efficiency (G:F) and residual feed intake (RFI) obtained by regression of DMI in relation to ADG and midtest metabolic BW (RFI). Alternatively, RFI was also obtained based on equations reported by the NRC's to estimate individual requirement and DMI (RFI calculated by the NRC [1996] equation [RFI]). The slope of the regression equation and its significance was used to evaluate the effect of efficiency indices (RFI, RFI, or G:F) on the traits studied. A mixed model was used considering RFI, RFI, or G:F and pen type as fixed effects and initial age as a covariate. For HR and EHP variables, day was included as a random effect. There was no relationship between efficiency indices and back fat depth measured by ultrasound or daily HR and EHP ( > 0.05). Because G:F is obtained in relation to BW, the slope of G:F was positive and significant ( RFI and RFI ( RFI. Oxygen consumption per beat was not related to G:F; however, it was lower for RFI- and RFI-efficient steers, and consequently, oxygen volume (mL·min·kg) and OP (μL O·beat·kg) were also lower ( RFI and RFI ( > 0.05); however, G:F-efficient steers showed lower hematocrit and hemoglobin concentrations ( < 0.05). Differences in EHP between efficient and inefficient animals were not directly detected. Nevertheless, differences in oxygen consumption and OP were detected, indicating that the OP methodology may be useful to predict growth efficiency. PMID

  12. Assessment of fracking for shale gas production from the viewpoints of energy policy and environmental policy. Opinion of the German Advisory Council on the Environment

    International Nuclear Information System (INIS)

    The proponents of shale gas production in Europe hope that the effects it has occasioned in the USA, namely falling prices and growing competitiveness, will also come about in Germany. However a decrease in gas prices is not to be expected, given Germany's comparatively modest shale gas reserves; these are even only enough to have a slightly moderating effect on the country's decline in domestic natural gas production. While it is true that the improved climate footprint of the USA is attributable to the increasing substitution of natural gas for coal, this is of little benefit to the global climate, since the coal does not remain in the ground but, as a result of the decline in domestic demand, is successfully exported as a cheap energy resource, leading to higher CO2 emissions elsewhere. For the purposes of the energy turnaround shale gas production is dispensable because it is not available short-term and gas demand will decrease over the medium term. Shale gas production is associated with a real risk of groundwater contamination or an inadvertent release of climatically harmful gases; however these are probably controllable with the aid of continued research as well as stringent environmental regulations and monitoring. Other consequences such as soil sealing and the loss of natural and recreational space cannot be avoided, however. Here the costs and benefit of shale gas production will have to be weighed against each other with great care. There are still major gaps in available knowledge on its environmental effects; these should be closed through representative pilot projects prior to commercial production.

    2014-01-01

    Elevated antigen-stimulated anti-inflammatory cytokine production appears to be a risk factor for upper respiratory tract illness in athletes. The purpose of this study was to determine the effects of prolonged exercise and hydration on antigen-stimulated cytokine production. Twelve healthy males cycled for 120 min at 60% [Formula: see text] on two occasions, either euhydrated or moderately hypohydrated (induced by fluid restriction for 24 h). Blood samples were collected before and after exercise and following 2 h recovery for determination of cell counts, plasma cortisol, and in vitro antigen-stimulated cytokine production by whole blood culture. Fluid restriction resulted in mean body mass loss of 1.3% and 3.9% before and after exercise, respectively. Exercise elicited a significant leukocytosis and elevated plasma cortisol, with no differences between trials. IL-6 production was significantly reduced 2 h postexercise (P hydration status was observed for the measured variables. Prolonged exercise appears to result in augmented anti-inflammatory cytokine release in response to antigen challenge, possibly coupled with acute suppression of proinflammatory cytokine production, corresponding with studies using mitogen or endotoxin as stimulant. Moderate hypohydration does not appear to influence these changes. PMID:24967270

    Dendritic cells are specialized antigen-presenting cells with immuno-modulating functions that are attractive for clinical applications for cancer immunotherapy. This study examined immunostimulatory functions of phytohemagglutinin (PHA)-stimulated adherent cells (PHA-Ad cells) from peripheral blood mononuclear cells (PBMCs) in dogs. PHA-Ad cells enhanced interferon-gamma from autologous PBMC in vitro. PHA-Ad cells also stimulated antigen-independent proliferation of peripheral blood lymphocytes. These results suggest that PHA-Ad cells from PBMC possess a stimulatory function to evoke anti-tumour immunity and that they demonstrate potential for therapeutic applications in dogs. PMID:19379211

  2. Atmospheric Release Advisory Capability

    International Nuclear Information System (INIS)

    The Atmospheric Release Advisory Capability (ARAC) project is a Department of Energy (DOE) sponsored real-time emergency response service available for use by both federal and state agencies in case of a potential or actual atmospheric release of nuclear material. The project, initiated in 1972, is currently evolving from the research and development phase to full operation. Plans are underway to expand the existing capability to continuous operation by 1984 and to establish a National ARAC Center (NARAC) by 1988. This report describes the ARAC system, its utilization during the past two years, and plans for its expansion during the next five to six years. An integral part of this expansion is due to a very important and crucial effort sponsored by the Defense Nuclear Agency to extend the ARAC service to approximately 45 Department of Defense (DOD) sites throughout the continental US over the next three years

  20. Process Improvement by Eliminating Mixing of Whole Blood Units after an Overnight Hold Prior to Component Production Using the Buffy Coat Method

    Full Text Available The elimination of a thorough manual mixing of whole blood (WB which takes place following the overnight hold, but before the first centrifugation step, during buffy coat component production at Canadian Blood Services (CBS was investigated. WB was pooled after donation and split. Pairs of platelet, red blood cell (RBC, and plasma components were produced, with half using the standard method and half using a method in which the mixing step was eliminated. Quality assessments included yield, pH, CD62P expression and morphology for platelets, hemoglobin, hematocrit, hemolysis, and supernatant K+ for RBCs, and volume and factor VIII activity levels for plasma. All components, produced using either method, met CBS quality control criteria. There were no significant differences in platelet yield between components produced with and without mixing. A significant difference was seen for RBC hemolysis at expiry (P=0.03, but for both groups, levels met quality control requirements. Noninferiority of components produced without mixing was confirmed for all parameters. Manual mixing is laborious and has a risk of repetitive strain for production staff and its significance is unclear. Elimination of this step will improve process efficiencies without compromising quality.

    Loss of sample integrity during specimen transport can lead to false-negative diagnostic results. In an effort to improve upon the status quo, we used dengue as a model RNA virus to evaluate the stabilization of RNA and antibodies in three commercially available sample stabilization products: Whatman FTA Micro Cards (GE Healthcare Life Sciences, Pittsburgh, PA), DNAstāble Blood tubes (Biomātrica, San Diego, CA), and ViveST tubes (ViveBio, Alpharetta, GA). Both contrived and clinical dengue-positive specimens were stored on these products at ambient temperature or 37°C for up to 1 month. Antibody and viral RNA levels were measured by enzyme-linked immunosorbent assay (ELISA) and quantitative reverse transcription polymerase chain reaction (qRT-PCR) assays, respectively, and compared with frozen unloaded controls. We observed reduced RNA and antibody levels between stabilized contrived samples and frozen controls at our earliest time point, and this was particularly pronounced for the FTA cards. However, despite some time and temperature dependent loss, a 94.6-97.3% agreement was observed between stabilized clinical specimens and their frozen controls for all products. Additional considerations such as cost, sample volume, matrix, and ease of use should inform any decision to incorporate sample stabilization products into a diagnostic testing workflow. We conclude that DNAstāble Blood and ViveST tubes are useful alternatives to traditional filter paper for ambient temperature shipment of clinical specimens for downstream molecular and serological testing.

    The objective of the study was to compare the carcass characteristics, meat quality, and blood parameters of slow and fast grown female broiler chickens fed in organic or conventional production system. The two genotypes tested were medium slow-growing chickens (SG, Hubbard Red JA) and commercial fast-growing chickens (FG, Ross 308). Both genotypes (each represented by 400 chickens) were divided into two sub-groups fed either organic (O) or conventional (C) systems. Chickens of each genotype and system were raised in a semi environmentally controlled poultry house until 21 d of age and were assigned to 5 pens of 40 chickens each. Then, O system chickens were transferred into an open-side poultry house with an outdoor run. At 81 d of age, 10 female chickens from each genotype and from each production system (n = 40) were randomly chosen to provide material for analysis, and were weighed and brought to the slaughterhouse to assess carcass characteristics and meat quality. The blood parameters were determined by using 5 female chickens from each genotype and from each production system (n = 20). FG had the higher live weight, along with carcass, breast, and thigh-drumstick weights compared to SG (pfacilities to optimize yield and quality while maintaining acceptable animal welfare standards.

    Full Text Available This experiment was conducted to investigate the effects of different levels of L-carnitine on productive performance, egg quality and blood parameters in laying hens. Forty-eight Hy-Line W-36 egg Layers were weighed at 90 weeks of age and randomly allocated into 16 cages (three hens per cage. Four dietary treatments were prepared by supplementing L-carnitine (0, 50, 100 and 150 mg/kg of diet to corn-soybean meal diet and offered ad libitum to hens. After two weeks of acclimatization, the eggs were weighed daily and feed intake as well as egg quality traits were measured biweekly. At the end of the experiment, two hens from each cage were selected to determine blood parameters and two eggs from each replicate were collected for cholesterol analysis. Results showed that L-carnitine supplementation at 100 and 150 mg/kg significantly increased egg production and egg mass, but decreased yolk cholesterol content. Laying hens receiving diet containing 50 mg/kg L-carnitine had significantly higher Hough unit, but lower progesterone than the hens fed control diet (P < 0.05. The results of this study showed that supplementing hens' diet with L-carnitine had beneficial effects on productive performance and decreased yolk cholesterol concentration; so it can be used as an effective supplement in the diet of laying hens.

    Cytokines play a key role in the regulation of cells of the immune system and also have been implicated in the pathogenesis of malignant diseases. The aim of this study was to evaluate cytokine profiles in patients with differentiated thyroid cancer (DTC) before and 7 days after radioactive iodine (131-I) therapy. Cytokine levels were determined in supernatants obtained from phytohemagglutinin-stimulated whole blood cultures of 13 patients with DTC and 13 control subjects. The concentrations of selected cytokines: Th1-interferon gamma (IFN-γ), interleukin 2 (IL-2) and tumor necrosis factor alpha (TNF-α); Th2-interleukin 4 (IL-4), interleukin 5 (IL-5), interleukin 13 (IL-13) and interleukin 10 (IL-10); Th9-interleukin-9 (IL-9); and Th17-interleukin 17 (IL-17A) were measured using multiplex cytokine detection systems for Human Th1/Th2/Th9/Th17/Th22. We have shown that peripheral blood cells of DTC patients produce significantly higher concentrations of Th2/Th9 cytokines (IL-5, IL-13 and IL-9) than control subjects. The 131-I therapy led to reduced secretion of Th2 cytokines (IL-4, IL-5 and IL-13). Despite this, the calculated cytokine ratios (Th1/Th2) in DTC patients before and 7 days after 131-I therapy were not different from those in healthy subjects. DTC patients have significantly higher concentrations of Th2/Th9 cytokines (IL-5, IL-13 and IL-9) than control subjects. There is no influence of hypothyroidism or stage of disease on cytokine production in DTC patients before 131-I therapy. The radioactive 131-I therapy leads to reduced secretion of Th2 cytokines (IL-4, IL-5 and IL-13). Additional studies are needed to determine the significance of these findings. PMID:25297452

  15. Ochratoxin A inhibits the production of tissue factor and plasminogen activator inhibitor-2 by human blood mononuclear cells: Another potential mechanism of immune-suppression

    International Nuclear Information System (INIS)

    The mycotoxin ochratoxin A (OTA), an ubiquitous contaminant of food products endowed with a wide spectrum of toxicity, affects several functions of mononuclear leukocytes. Monocytes/macrophages play a major role in fibrin accumulation associated with immune-inflammatory processes through the production of tissue factor (TF) and plasminogen activator inhibitor 2 (PAI-2). We studied the effect of OTA on TF and PAI-2 production by human blood mononuclear cells (MNC). The cells were incubated for 3 or 18 h at 37 deg. C with non toxic OTA concentrations in the absence and in the presence of lipopolysaccharide (LPS) or other inflammatory agents. TF activity was measured by a one-stage clotting test. Antigen assays were performed by specific ELISAs in cell extracts or conditioned media and specific mRNAs were assessed by RT-PCR. OTA had no direct effect on TF and PAI-2 production by MNC. However, OTA caused a dose-dependent reduction in LPS-induced TF (activity, antigen and mRNA) and PAI-2 (antigen and mRNA) production with > 85% inhibition at 1 μg/ml. Similar results were obtained when monocyte-enriched preparations were used instead of MNC. TF production was also impaired by OTA (1 μg/ml) when MNC were stimulated with phorbol myristate acetate (98% inhibition), IL-1β (83%) or TNF-α (62%). The inhibition of TF and PAI-2 induction might represent a hitherto unrecognized mechanism whereby OTA exerts immunosuppressant activity

    The influence of perioperative transfusion (PT) on outcome following surgery for gastric cancer (GC) remains controversial, with randomized trials lacking and observational series confounded by patient risk factors. This analysis determines the association between reception of leukocyte-depleted blood products and post-operative survival for GC.Data from 610 patients who underwent curative surgery for GC in a German tertiary care clinic from 2001 to 2013 were included. Kaplan-Meier survival curves and Cox proportional hazards regression were applied to determine the association of PT and clinical and patient risk factors for overall and relapse-free survival. Propensity score analysis was performed to adjust for observational biases in reception of PT.Higher Union International Contre le Cancer/American Joint Committee on Cancer (UICC/AJCC)-stages (P female gender (P = 0.03). In the adjusted propensity score weighted analysis, PT remained associated with an increased risk of death (hazard ratio (HR): 1.31, 95% CI: 1.01-1.69, P = 0.04).Because of the association of PT with negative influence on patient survival following resection for GC, risks from application of blood products should be weighed against the potential benefits.

    Oropharyngeal cancer is a significant public health issue in the world. The incidence of oropharyngeal cancer has been increased among people who have habit of chewing smokeless tobacco (SLT) in Pakistan. The aim of present study was to evaluate the concentration of nickel (Ni) in biological samples (whole blood, serum) of oral (n = 95) and pharyngeal (n = 84) male cancer patients. For comparison purposes, the biological samples of healthy age-matched referents (n = 150), who consumed and did not consumed SLT products, were also analyzed for Ni levels. As the Ni level is very low in biological samples, a preconcentration procedure has been developed, prior to analysis of analyte by flame atomic absorption spectrometry (FAAS). The Ni in acid-digested biological samples was complexed with ammonium pyrrolidinedithio carbamate (APDC), and a resulted complex was extracted in a surfactant Triton X-114. Acidic ethanol was added to the surfactant-rich phase prior to its analysis by FAAS. The chemical variables, such as pH, amounts of reagents (APDC, Triton X-114), temperature, incubation time, and sample volume were optimized. The resulted data indicated that concentration of Ni was higher in blood and serum samples of cancer patients as compared to that of referents who have or have not consumed different SLT products (p = 0.012-0.001). It was also observed that healthy referents who consumed SLT products have two to threefold higher levels of Ni in both biological samples as compared to those who were not chewing SLT products (p < 0.01).

    Niemann-Pick type C1 (NPC1) disease is a rare progressive neurodegenerative disorder characterized by endolysosomal cholesterol accumulation. Previous studies implicating oxidative stress in NPC1 disease pathogenesis raised the possibility that non-enzymatic formation of cholesterol oxidation products could serve as disease biomarkers. We measured these metabolites in the plasma and tissues of the Npc1−/− mouse model and found several cholesterol oxidation products that were elevated in Npc1−...

    Mesenchymal stem cells (MCSs) have been shown to have therapeutic potential in multiple disease states associated with vascular instability including traumatic brain injury (TBI). In the present study, Tissue Inhibitor of Matrix Metalloproteinase-3 (TIMP3) is identified as the soluble factor produced by MSCs that can recapitulate the beneficial effects of MSCs on endothelial function and blood brain barrier (BBB) compromise in TBI. Attenuation of TIMP3 expression in MSCs completely abrogates the effect of MSCs on BBB permeability and stability, while intravenous administration of rTIMP3 alone can inhibit BBB permeability in TBI. Our results demonstrate that MSCs increase circulating levels of soluble TIMP3, which inhibits VEGF-A induced breakdown of endothelial AJs in vitro and in vivo. These findings elucidate a clear molecular mechanism for the effects of MSCs on the BBB in TBI, and directly demonstrate a role for TIMP3 in regulation of BBB integrity. PMID:23175708

  3. Polysaccharides from Inonotus obliquus sclerotia and cultured mycelia stimulate cytokine production of human peripheral blood mononuclear cells in vitro and their chemical characterization.

    Science.gov (United States)

    Xu, Xiangqun; Li, Juan; Hu, Yan

    2014-08-01

    Inonotus obliquus is an edible and medicinal mushroom to treat many diseases. In the present study, polysaccharides and fractions were isolated and purified by DEAE-52 and Sephadex G-200 chromatography from I. obliquus wild sclerotia, culture broth and cultured mycelia under submerged fermentation. The extracts and fractions could significantly induce the secretion of TNF-α, IFN-γ, IL-1β, and IL-2 in human peripheral blood mononuclear cells (PBMCs) and showed no toxicity to PBMCs. The stimulation effect of the six extracts and eight fractions on the four-cytokine production was dose-dependent. Sclerotial polysaccharides were more effective in the four-cytokine production at 150 μg/ml while exopolysaccharides and endopolysacchrides showed a much better effect on IL-1β production at 30 μg/ml. Purified fractions from exopolysaccharides and endopolysaccharides were more effective than the fraction from sclerotia in most cytokine production. These heteropolysaccharide-protein conjugates mainly contained glucose, galactose, and mannose. Protein content, molecular weight, monosaccharide molar ratio, and anomeric carbon configuration differed from each other and had effects on the cytokine induction activity of the polysaccharides to some extent.

    Anderson, Koren C; Teuber, Suzanne S

    2010-03-01

    Tree nuts, including walnuts, are important elicitors of food allergy. We examined the ability of walnut kernel polyphenolics and purified ellagic acid (EA) to modulate cytokine production and cellular proliferation from stimulated human peripheral blood mononuclear cells (PBMC). IL-13 and TNF-alpha production decreased while no change was observed in IL-4 production. Paradoxically, EA and the walnut polyphenolics all significantly and dose-dependently inhibited stimulated [phytohemagglutin (PHA), alpha-CD3, and phorbol myristate acetate (PMA)/ionomycin] PBMC proliferation while simultaneously increasing IL-2 production. When added at time 0 min and 2 h, EA dose-dependently inhibited PHA-induced proliferation. However, at 30 min and 1 h, low doses of EA (10 and 1 muM) significantly increased proliferation above that of PHA alone, although higher doses led to inhibition. Our data do not support the hypothesis that walnut polyphenolics skew a cytokine response toward Th2 in an in vitro environment. However, immunomodulatory effects are present, including an inhibition of cellular proliferation despite no decrease in IL-4 or IL-2. PMID:20388139

    2016-07-01

    This study tested the hypothesis that sickle red blood cell (SS-RBC) induce Toll-like receptors (TLR) and Nod-like receptor family, pyrin domain containing 3 (NLRP3)- inflammasome expression in peripheral blood mononuclear cells (PBMC). TLR and NLRP3 inflammasome could contribute to the maintenance of the inflammatory status in sickle cell anemia (SCA) patients, since SS-RBC act as danger signals activating these pathways. In this study, first, we evaluated TLR (2, 4, 5 and 9), NLRP3, Caspase-1, interleukin (IL)-1β and IL-18 expression in PBMC freshly isolated from SCA patients (SS-PBMC) in comparison with PBMC from healthy individuals (AA-PBMC). In the second moment, we investigated whether SS-RBC could interfere with the expression of these molecules in PBMC from healthy donor, in the absence or presence of hydroxyurea (HU) in vitro. TLRs and NLRP3 inflammasome expression were investigated by qPCR. IL-1β, Leukotriene-B4 (LTB4) and nitrite production were measured in PBMC (from healthy donor) culture supernatants. TLR2, TLR4, TLR5, NLRP3 and IL-1β were highly expressed in SS-PBMC when compared to AA-PBMC. Additionally, SS-RBC induced TLR9, NLRP3, Caspase-1, IL-1β and IL-18 expression and induced IL-1β, LTB4 and nitrite production in PBMC cultures. HU did not prevent TLR and NLRP3 inflammasome expression, but increased TLR2 and IL-18 expression and reduced nitrite production. In conclusion, our data suggest that TLR and inflammasome complexes may be key inducers of inflammation in SCA patients, probably through SS-RBC; also, HU does not prevent NLRP3 inflammasome- and TLR-dependent inflammation, indicating the need to develop new therapeutic strategies to SCA patients that act with different mechanisms of those observed for HU.

    Objective:To study the role of Th1fTh2 cytokines in the pathogenesis of recurrent genital herpes (RGH), and to better understand the relationship between them.Methods: A two-color immunofluorescent staining of cell surface antigen and intracellular cytokines for flow cytometric analysis was used for CD3, IL-2, IL-10, IL-12,IFN-γ and TNF-α in CD3+ T-lymphocytes in activated peripheral blood mononuclear cells of patients with RGH.Results: Compared to controls, patients with RGH showed fewer CD3+T cells (P<0.05) and IL-2 producing and IFN-γ producing T cells (P<0.02 and P<0.001, respectively)after in vitro stimulation with PMA and ionomycin in the presence of a protein transport inhibitor. More IL-10 producing and IL-12 producing T cells were found in patients with RGH (P<0.01). There was no significant difference in the number of TNF-α producing cells between RGH patients and controls (P<0.05).Conclusion: RGH patients showed relatively more Th2 cytokines. The imbalance between Th1 and Th2 cytokines results in inhibitory effects on a series of cell-immune responses, which may play an important role in the pathogenesis of RGH.

    This study was conducted to determine the effects of feeding by-product feed (BF)-based silage on the performance, blood metabolite parameters, and carcass characteristics of Hanwoo steers. The BF-based silage was composed of 50% spent mushroom substrate, 21% recycled poultry bedding, 15% cut ryegrass straw, 10.8% rice bran, 2% molasses, 0.6% bentonite, and 0.6% microbial additive (on a wet basis), and ensiled for over 5 d. Fifteen steers were allocated to three diets during the growing and fattening periods (3.1 and 9.8 months, respectively): a control diet (concentrate mix and free access to rice straw), a 50% BF-based silage diet (control diet+50% of maximum BF-based silage intake), and a 100% BF-based silage diet (the same amount of concentrate mix and ad libitum BF-based silage). The BF-based silage was fed during the growing and fattening periods, and was replaced with larger particles of rice straw during the finishing period. After 19.6 months of the whole period all the steers were slaughtered. Compared with feeding rice straw, feeding BF-based silage tended (p = 0.10) to increase the average daily gain (27%) and feed efficiency (18%) of the growing steers, caused by increased voluntary feed intake. Feeding BF-based silage had little effect on serum constituents, electrolytes, enzymes, or the blood cell profiles of fattening steers, except for low serum Ca and high blood urea concentrations (pgrade, or quality traits such as meat color, fat color, texture, maturity, marbling score, or quality grade. However, it improved good quality grade (1(+) and 1(++)) appearance rates (60% for the control group vs 100% for the BF-based silage-fed groups). In conclusion, cheap BF-based silage could be successfully used as a good quality roughage source for beef cattle. PMID:25557813

    2009-11-01

    Cimicifuga racemosa (black cohosh) is commonly used in traditional medicines as treatment for menopausal symptoms and as an antiinflammatory remedy. To clarify the mechanism of action and active principle for the antiinflammatory action, the effects of aqueous C. racemosa root extracts (CRE) and its major constituents on the release of the proinflammatory cytokines IL-6, TNF-alpha, IFN-gamma, and the chemokine IL-8 were investigated in lipopolysaccharide (LPS)-stimulated whole blood of healthy volunteers. CRE (3 microg/microL and 6 microg/microL) reduced LPS-induced release of IL-6 and TNF-alpha in a concentration- and time-dependent manner and almost completely blocked release of IFN-gamma into the plasma supernatant. Except for IFN-gamma, these effects were attenuated at longer incubation periods. IL-8 secretion was stimulated by CRE. As shown by quantitative real-time RT-PCR, effects on cytokines were based on preceding changes in mRNA levels except for IL-8. According to their content in CRE, the phenolcarboxylic compounds caffeic acid, ferulic acid, and isoferulic acid, as well as the triterpene glycosides 23-epi-26-deoxyactein and cimigenol-3-O-xyloside, were tested at representative concentrations. Among these, isoferulic acid was the prominent active principle in CRE, responsible for the observed inhibition of IL-6, TNF-alpha, and IFN-gamma, but not for IL-8 stimulation. The effect of this compound may explain the antiinflammatory activities of CRE and its beneficial actions in rheumatism and other inflammatory diseases. PMID:19935904

  9. Determination of Microbial Nitrogen Production by Using Urinary Allantoin and Blood Metabolite Concentrate in Growing Brahman Cattle Fed the Different Proportion of Roughage and Concentrate in Diets

    International Nuclear Information System (INIS)

    Determination of microbial nitrogen synthesis by using urinary allantoin and blood metabolite for evaluating the efficiency of feed utilization, in this study was conducted by using four Brahman bulls (about 1 year old). Animals were fed ad libitum with 4 fixed diets of four combinations of pineapple fibre (P) and concentrate (C) in the proportions, on dry matter basis of 0.8:0.2 (P80:C20), 0.6:0.04(P60:C40), 0.4:0.6(P40:C60) and 0.2:0.8 (P20:C80). The experiment was designed as a 4x4 Latin square design The Results showed that increasing in the proportion of concentrate linearly increased the rumen microbial nitrogen production (p<0.001), the concentrations of Insulin and urea-N in plasma and the concentration of urea-N in the urine, but not affected on the concentrations of glucose and creatinine in plasma. In conclusion, the using of allantoin urinary associated with blood metabolite can evaluate the accuracy in evaluation of feed utilization in Brahman cattle

    Forty-eight castrated male goats were used to determine the effects of feeding green tea by-products (GTB) on growth performance, meat quality, blood metabolites and immune cell proliferation. Experimental treatments consisted of basal diets supplemented with four levels of GTB (0%, 0.5%, 1.0% or 2.0%). Four replicate pens were assigned to each treatment with three goats per replicate. Increasing dietary GTB tended to linearly increase the overall average weight gain and feed intake (p = 0.09). Water holding capacity, pH and sensory attributes of meat were not affected by GTB supplementation, while cooking loss was reduced both linearly and quadratically (p goat meat were improved by GTB supplementation. Increasing dietary GTB quadratically increased protein and decreased crude fat (p goat meat. The proportions of monounsaturated fatty acid, polyunsaturated fatty acid (PUFA) and n-6 PUFA increased linearly (p meat were lower in the 2.0% GTB-supplemented group in all storage periods (p meat quality, blood metabolites and immune cell proliferation when supplemented as a feed additive in goat diet.

    Full Text Available   Stem cells are naïve or master cells. This means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. Stem cells are found in many parts of the human body, although some sources have richer concentrations than others. Some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and human embryos, which last one are controversial and their use can be illegal in some countries. Cord blood is a sample of blood taken from a newborn baby's umbilical cord. It is a rich source of stem cells, umbilical cord blood and tissue are collected from material that normally has no use following a child’s birth. Umbilical cord blood and tissue cells are rich sources of stem cells, which have been used in the treatment of over 80 diseases including leukemia, lymphoma and anemia as bone marrow stem cell potency.  The most common disease category has been leukemia. The next largest group is inherited diseases. Patients with lymphoma, myelodysplasia and severe aplastic anemia have also been successfully transplanted with cord blood. Cord blood is obtained by syringing out the placenta through the umbilical cord at the time of childbirth, after the cord has been detached from the newborn. Collecting stem cells from umbilical blood and tissue is ethical, pain-free, safe and simple. When they are needed to treat your child later in life, there will be no rejection or incompatibility issues, as the procedure will be using their own cells. In contrast, stem cells from donors do have these potential problems. By consider about cord blood potency, cord blood banks (familial or public were established. In IRAN, four cord blood banks has activity, Shariati BMT center cord blood bank, Royan familial cord blood banks, Royan public cord blood banks and Iranian Blood Transfusion Organ cord blood banks. Despite 50,000 sample which storage in these banks, but the

    Full Text Available In recent times, human cell-based assays are gaining attention in assessments of immunomodulatory effects of chemicals. In the study here, the possible effects of cypermethrin and mancozeb on lymphocyte proliferation and proinflammatory (tumor necrosis factor (TNF- α and immunoregulatory cytokine (interferon- (IFN- γ, interleukins (IL 2, 4, 6, and 10 formation in vitro were investigated. Human peripheral blood mononuclear cells (PBMC were isolated and exposed for 6 hr to noncytotoxic doses (0.45–30 µM of cypermethrin or mancozeb in the presence of activating rat S9 fraction. Cultures were then further incubated for 48 or 72 hr in fresh medium containing phytohemagglutinin (10 µg/mL to assess, respectively, effects on cell proliferation (BrdU-ELISA method and cytokine formation (flow cytometric bead immunoassays. Mancozeb induced dose-dependent increases in lymphocyte proliferation, inhibition of production of TNFα and the TH2 cytokines IL-6 and IL-10, and an increase in IFNγ (TH1 cytokine production (at least 2-fold compared to control; mancozeb also induced inhibition of IL-4 (TH2 and stimulated IL-2 (TH1 production, albeit only in dose-related manners for each. In contrast, cypermethrin exposure did not cause significant effects on proliferation or cytokine profiles. Further studies are needed to better understand the functional significance of our in vitro findings.

    Objectives were to determine associations between percentage pregnancy loss (PPL) in dairy cattle and: (i) pregnancy diagnosis by ultrasonography; (ii) pregnancy diagnosis by serum pregnancy-specific protein B (PSPB) concentrations, with or without serum progesterone concentrations; and (iii) production and environmental factors. This study included 149 822 pregnancy diagnoses conducted over 13 years in Holstein-Friesian cows in Hungarian dairy herds. The following were determined: PPL in cows diagnosed pregnant by transrectal ultrasonography 29-42 days after artificial insemination (AI; n = 11 457); PPL in cows diagnosed pregnant by serum PSPB 29-35 days after AI (n = 138 365); and PPL and its association with serum progesterone concentrations, PSPB and production/environmental variables. The definition of PPL was percentage of cows initially diagnosed pregnant based on ultrasonography or PSPB, but not pregnant when examined by transrectal palpation 60 -70 days after AI. The PPL was lower (p 1.1 ng/ml) was lowest (15.0%), whereas cows with low concentrations of both PSPB and progesterone (0.6-1.1 and <2 ng/ml, respectively) had the highest PPL (76.3%; p < 0.0001). Furthermore, PPL was higher in cows with advanced parity and with high milk production, when ambient temperatures were high, although body condition score (BCS) had no effect on PPL. Finally, there were no significant associations between serum PSPB and environmental temperatures or number of post-partum uterine treatments. PMID:27198072

    The Retrovirus Epidemiology Donor Study (REDS), conducted from 1989 to 2001, and the REDS-II, conducted from 2004 to 2012, were National Heart, Lung, and Blood Institute-funded, multicenter programs focused on improving blood safety and availability in the United States. The REDS-II also included international study sites in Brazil and China. The 3 major research domains of REDS/REDS-II have been infectious disease risk evaluation, blood donation availability, and blood donor characterization. Both programs have made significant contributions to transfusion medicine research methodology by the use of mathematical modeling, large-scale donor surveys, innovative methods of repository sample storage, and establishing an infrastructure that responded to potential emerging blood safety threats such as xenotropic murine leukemia virus-related virus. Blood safety studies have included protocols evaluating epidemiologic and/or laboratory aspects of human immunodeficiency virus, human T-lymphotropic virus 1/2, hepatitis C virus, hepatitis B virus, West Nile virus, cytomegalovirus, human herpesvirus 8, parvovirus B19, malaria, Creutzfeldt-Jakob disease, influenza, and Trypanosoma cruzi infections. Other analyses have characterized blood donor demographics, motivations to donate, factors influencing donor return, behavioral risk factors, donors' perception of the blood donation screening process, and aspects of donor deferral. In REDS-II, 2 large-scale blood donor protocols examined iron deficiency in donors and the prevalence of leukocyte antibodies. This review describes the major study results from over 150 peer-reviewed articles published by these 2 REDS programs. In 2011, a new 7-year program, the Recipient Epidemiology and Donor Evaluation Study-III, was launched. The Recipient Epidemiology and Donor Evaluation Study-III expands beyond donor-based research to include studies of blood transfusion recipients in the hospital setting and adds a third country, South Africa

The fowls were divided in three groups (26 females and 3 males in each group. They were reared in a free-range management system with elements of organic production. The experimental treatments were as followed: first (control group without dietary supplement, second group with 100 mg Zinteral 35 per kg diet containing 35 mg/kg zinc oxide, third group with the same amount of Zinteral 35 together with 250 mg vitamin C per kg diet. During the three periods with different ambient temperature, the hens supplemented either with zinc alone (second group or co-administered zinc + vitamin C (third group had significantly lower levels of plasma corticosterone (P<0.001, serum cholesterol (P<0.05 and glucose (P<0.05 than those from the first (control group. The differences between the third and the first groups were bigger versus those between the second and the first groups. For the entire period (March 1 and June 21, egg production was higher by 2.22 % and 4.60 % in the second and third groups respectively in comparison to the first group. The combination of 100 mg Zinteral 35 and 250 mg vitamin C per 1 kg diet exhibited a synergistic effect in reducing cold and heat stress in laying hens and increased their egg production.

    Reddy, Vishwanatha R A P; Trus, Ivan; Desmarets, Lowiese M B; Li, Yewei; Theuns, Sebastiaan; Nauwynck, Hans J

    2016-01-01

    In the present study, the replication kinetics of nephropathogenic (B1648) and respiratory (Massachusetts-M41) IBV strains were compared in vitro in respiratory mucosa explants and blood monocytes (KUL01(+) cells), and in vivo in chickens to understand why some IBV strains have a kidney tropism. B1648 was replicating somewhat better than M41 in the epithelium of the respiratory mucosa explants and used more KUL01(+) cells to penetrate the deeper layers of the respiratory tract. B1648 was productively replicating in KUL01(+) monocytic cells in contrast with M41. In B1648 inoculated animals, 10(2.7-6.8) viral RNA copies/100 mg were detected in tracheal secretions at 2, 4, 6, 8, 10 and 12 days post inoculation (dpi), 10(2.4-4.5) viral RNA copies/mL in plasma at 2, 4, 6, 8, 10 and 12 dpi and 10(1.8-4.4) viral RNA copies/10(6) mononuclear cells in blood at 2, 4, 6 and 8 dpi. In M41 inoculated animals, 10(2.6-7.0) viral RNA copies/100 mg were detected in tracheal secretions at 2, 4, 6, 8 and 10 dpi, but viral RNA was not demonstrated in plasma and mononuclear cells (except in one chicken at 6 dpi). Infectious virus was detected only in plasma and mononuclear cells of the B1648 group. At euthanasia (12 dpi), viral RNA and antigen positive cells were detected in lungs, liver, spleen and kidneys of only the B1648 group and in tracheas of both the B1648 and M41 group. In conclusion, only B1648 can easily disseminate to internal organs via a cell-free and -associated viremia with KUL01(+) cells as important carrier cells. PMID:27412035

  2. Effect of By-product Feed-based Silage Feeding on the Performance, Blood Metabolites, and Carcass Characteristics of Hanwoo Steers (a Field Study)

    Kim, Y. I.; Park, J. M.; Lee, Y. H.; Lee, M.; Choi, D. Y.; Kwak, W. S.

    2015-01-01

    This study was conducted to determine the effects of feeding by-product feed (BF)-based silage on the performance, blood metabolite parameters, and carcass characteristics of Hanwoo steers. The BF-based silage was composed of 50% spent mushroom substrate, 21% recycled poultry bedding, 15% cut ryegrass straw, 10.8% rice bran, 2% molasses, 0.6% bentonite, and 0.6% microbial additive (on a wet basis), and ensiled for over 5 d. Fifteen steers were allocated to three diets during the growing and fattening periods (3.1 and 9.8 months, respectively): a control diet (concentrate mix and free access to rice straw), a 50% BF-based silage diet (control diet+50% of maximum BF-based silage intake), and a 100% BF-based silage diet (the same amount of concentrate mix and ad libitum BF-based silage). The BF-based silage was fed during the growing and fattening periods, and was replaced with larger particles of rice straw during the finishing period. After 19.6 months of the whole period all the steers were slaughtered. Compared with feeding rice straw, feeding BF-based silage tended (p = 0.10) to increase the average daily gain (27%) and feed efficiency (18%) of the growing steers, caused by increased voluntary feed intake. Feeding BF-based silage had little effect on serum constituents, electrolytes, enzymes, or the blood cell profiles of fattening steers, except for low serum Ca and high blood urea concentrations (psilage did not affect cold carcass weight, yield traits such as back fat thickness, longissimus muscle area, yield index or yield grade, or quality traits such as meat color, fat color, texture, maturity, marbling score, or quality grade. However, it improved good quality grade (1+ and 1++) appearance rates (60% for the control group vs 100% for the BF-based silage-fed groups). In conclusion, cheap BF-based silage could be successfully used as a good quality roughage source for beef cattle. PMID:25557813

    study of the historical rise and current workings of safety practices in the Danish blood system. Here, we identify a strong focus on contamination in order to avoid 'tainted blood', at the expense of working with risks that could be avoided through enhanced blood monitoring practices. Of further...... significance to this focus are the social dynamics found at the heart of safety practices aimed at avoiding contamination. We argue that such dynamics need more attention, in order to achieve good health outcomes in transfusion medicine. Thus, we conclude that, to ensure continuously safe blood systems, we...... need to move beyond the bifurcation of the social and medical aspects of blood supply as two separate issues and approach social dynamics as key medical safety questions....

  6. Production of soluble recombinant proteins with Kell, Duffy and Lutheran blood group antigen activity, and their use in screening human sera for Kell, Duffy and Lutheran antibodies.

    Science.gov (United States)

    Ridgwell, K; Dixey, J; Scott, M L

    2007-10-01

    The aim of this study was to show that soluble recombinant (sr) proteins can mimic blood group antigens and be used to screen human sera for blood-group-specific antibodies. The blood of all pregnant women and pretransfusion patients should be screened for blood-group-specific antibodies to identify and monitor pregnancies at risk of haemolytic disease of the foetus and newborn (HDFN), and to prevent haemolytic transfusion reactions. Current antibody screening and identification methods use human red blood cell panels, which can complicate antibody identification if more than one antibody specificity is present. COS-7 cells were transfected to produce sr forms of the extracellular domains of the red blood cell membrane proteins that express Kell, Duffy or Lutheran blood group antigens. These sr proteins were used to screen for and identify anti-Kell, anti-Duffy or anti-Lutheran blood-group-specific allo-antibodies in human sera by haemagglutination inhibition and in solid-phase enzyme-linked immunosorbent assays (ELISAs). There is a positive correlation (correlation coefficient 0.605, P value 0.002) between antibody titre by standard indirect antiglobulin test (IAT) and signal intensity in the ELISA test. This work shows that sr proteins can mimic blood group antigens and react with human allogeneic antibodies, and that such proteins could be used to develop solid-phase, high-throughput blood group antibody screening and identification platforms.

  9. Blood transfusion economics in Greece.

    Science.gov (United States)

    Kyriopoulos, J E; Michail-Merianou, V; Gitona, M

    1995-01-01

    This paper describes the organizational structure and the economic impact of blood donation and transfusion in Greece and discusses some alternative aspects of its financing and its costing policy. The cost of blood transfusion is rising in Greece and amounts to nearly 15 billion drachmas per year due to the constant increase in demand and consequently, the price of each unit of blood. The production and distribution of blood on national scale involves meeting the demand for 500.000 units. Blood is mostly given by the friends and relatives of patients (55%) and by voluntary blood donation (30%). Approximately 50% of the blood produced is used in surgery, 20% for cases of beta-thalassaemia, 10% for emergencies and 20% for internal medicine cases. The blood transfusion system is totally funded by the state budget and the value to users is free of charge. The way in which blood is collected and processed differs from one geographical area to another and the unit cost depends on the size of the department concerned, ranging from 60-150 $. The need to control costs and restrain expenditure, in conjunction with guarantees of sufficiency and quality, makes it essential that measures should be taken to introduce economies of scale and encourage competition among blood providers, for increased production, components preparation and rational usage of blood. The introduction of a costing policy becomes necessary in this effort to achieve cost-containment techniques. PMID:8581182

  11. Dose-effect relationship in production of dicentrics and rings in blood lymphocytes of individuals living in high background radiation area

    International Nuclear Information System (INIS)

    Objective: To explore the dose-effect relationship in the production of chromosome aberrations by high background radiation by using statistically appropriate individual measurements. Methods: Chromosome analysis was performed in separated blood lymphocytes of 39 family members of different ages from either high background radiation area (HBRA) or control area (CA). Individual cumulative doses ranged from 23.9-261.3 and 5.2-29.8 mGy for HBRA and CA, respectively. A total of about 100,000 cells were scored and dicentric and ring chromosome (dic + Rc) aberrations recorded. Results: In the case of HBRA, individual chromosome aberration frequencies increased with age within each family. The increasing trend was in general not significantly different among families. The increase in individual aberration was closely correlated with age and cumulative dose. Age-and dose-effect relationship fit well the linear equation: Y = 0.0448X + 0.4913 (R2 = 0.7814) for age and Y 0.0156X + 0.5715 (R2 = 0.7061) for cumulative dose, respectively. In the case of CA, there was no significant difference in aberration yields among individuals of different ages, and the group mean aberration frequency was 1.24 +- 0.69 x 10-3. Conclusions: Dic and Rc can continuously accumulate over a lifetime chronic low dose exposures, and can serve as a reliable biological indicator. However, the ultimate sensitivity is about 50 mGy

    2016-04-01

    This study evaluated the effect of Yucca schidigera extract on productive performance, egg quality, blood metabolites, immune function, and antioxidant parameters in laying hens. A total of 96 36-week-old hens were allocated into four groups, the control diet or the diet supplemented with 50, 100, or 150 mg/kg of yucca extract, from 36 to 52 weeks of age. Hens were divided into four equal groups replicated six times with four hens per replicate. As a result of this study, there were no linearly or quadratically differences in body weight change (BWC), feed consumption (FC), feed conversion ratio (FCR), and egg weight (EW) due to yucca treatments at different ages, except FCR and EW that were improved with yucca supplementation during 36-40 weeks of age. Supplemental dietary yucca up to 100 mg/kg diet led to significant improvement in egg number (EN) and egg mass (EM). Egg qualities were not linearly or quadratically affected by yucca treatments except shell thickness was quadratically (P hen diets resulted in a significant linear (P laying hens. PMID:26662788

  17. Natural product of wild Zingiberaceae Elettariopsis slahmong: biopesticide to control the vector of banana blood disease bacterium in West Sumatera, Indonesia.

    Science.gov (United States)

    Nasir, N; Dharma, A; Efdi, M; Yuhendra; Eliesti, F

    2013-01-01

    Banana is one of the most important food crops in Indonesia. Its production is greater than any other agricultural commodity. With the population of 230 million in 2010, banana was consumed up to three million tons in this country. However, Banana Blood Disease Bacterium (BDB), one of the most devastating banana pathogens in the world, which is only found in Indonesia, threatens not only the growth of this plant but also the lives and the livelihoods for most of the Indonesian society. BDB is caused by a lethal bacteria, Ralstonia solanacearum Phylotype-4, which infects a wide range of bananas, from bananas used for consumption to wild bananas. In West Sumatera, the disease killed 1.40% of bananas in 1998, and then increased dramatically to 37.9% in 2003. The total banana production dropped to 62% in this province. The search for controlling the vector has led to the pre-investigation of Wild Zingiberaceae Elettariopsis slahmong C.K. Lim which has a stink bug odour similar to a methidathion insecticide. The plant was collected around the conservation area of Lembah Anal in West Sumatra. The goal of this study was to investigate the effectiveness of natural insecticides compound contained in E. slahmong against D. melanogaster. This study tested the effect of E. slahmong on the mortality, anti-feedant and repellent levels against Drosophila melanogaster, the vector of BDB. The essential oil of E. slahmong was obtained by steam distillation of fresh rhizomes, pseudo stems and leaves. We found that the extract of E. slahmong significantly affected the mortality of D. melanogaster of 30-40% and also acted as an antifeedant (with success rate of 73-93%) and repellent (with success rate of 99-99.6%). The long- term objective of this study is to develop green biopesticide to control BDB in Indonesia, based on an environmentally friendly pest management. PMID:25151825

    In 2009, swine flu (H1N1) had spread significantly to levels that threatened pandemic influenza. There have been many treatments that have arisen for patients since the WHO first reported the disease. Although some progress in controlling influenza has taken place during the last few years, the disease is not yet under control. The development of new and less expensive anti-influenza drugs is still needed. Here, we show that sesamin from the seeds of the Thai medicinal plant Sesamum indicum has anti-inflammatory cytokines in human peripheral blood mononuclear cells (PBMCs) induced by 2009 influenza virus type A H1N1. In this study, the combinatorial screening method combined with the computational approach was applied to investigate the new molecular binding structures of sesamin against the 2009 influenza virus type A H1N1 (p09N1) crystallized structure. Experimental methods were applied to propose the mechanisms of sesamin against cytokine production from H1N1-induced human PBMC model. The molecular dynamics simulation of sesamin binding with the p09N1 crystallized structure showed new molecular binding structures at ARG118, ILE222, ARG224, and TYR406, and it has been proposed that sesamin could potentially be used to produce anti-H1N1 compounds. Furthermore, the mechanisms of sesamin against cytokine production from influenza type A H1N1-induced PBMCs by ELISA and signaling transduction showed that sesamin exhibits the ability to inhibit proinflammatory cytokines, IL-1β and TNF-α, and to enhance the activity of the immune cell cytokine IL-2 via downregulating the phosphorylated JNK, p38, and ERK1/2 MAPK signaling pathways. This information might very well be useful in the prevention and treatment of immune-induced inflammatory disorders. PMID:26424131
