    2015-05-01

    Full Text Available There is an expectation that the blood will always be there when it is really needed. Blood donor volunteers constitute the main supply source in an effective blood supply chain management. They feed blood stocks through their donation. In an emergency situation, if the stocks are insufficient, the only source of blood supply will be the people who come to the health center and donate the blood on a voluntary basis. It is certain that time is a very important component in such situation. For this reason, the health care center should call the nearest available donor in order to ensure to get the service as quickly as possible. A smart phone application is developed to facilitate the identification of the nearest available blood donor volunteer and the communication with him/her in the emergency situations where the blood can’t be supplied through the blood banks’ stocks. In this paper this application will be presented.

    Blood donation (BD) is a noble act and mobile applications (apps) can help increase awareness about it. This paper analyzes and assesses the characteristics of free apps for BD as regards features and functionality. A search in Google Play, Apple Apps store, Blackberry App World and Windows Mobile App store was carried out to select 169 free BD apps from the 188 apps identified. The results presented in this paper show that the majority of the apps selected have been developed for the Android operating system. Moreover, most of the apps selected are available to help users search for donors. Few of the apps could not be installed and/or accessed. Of those that could be installed: half of them do not require any kind of authentication; a few of them are available in more than one language; half of them have a geographical restriction; around 60 % of them do not notify the user of BD events and requests; one, which is available for Android and iOS, can connect with a laboratory; around 45 % of them allow users to share information via social networks, and the majority of them do not provide BD recommendations. These results are used as a basis to provide app developers with certain recommendations. There is a need for better BD apps with more features in order to increase the number of volunteer donors.

  13. Radiolabelled blood elements techniques and clinical applications

    International Nuclear Information System (INIS)

    Over the past few years, in nuclear medicine, the diagnostic applications of radiolabelled blood elements in general, and of radiolabelled white blood cells in particular, have become increasingly popular. This is primarily due to the introduction of lipid soluble 111In-oxine as an agent, which not only is an excellent and a reliable tracer for blood cells but also enables the investigators to study the in vivo cell kinetics and map the localization of labelled cells by external gamma scintigraphy. The tracer has the modest half life of 67 hours and decays with the emission of two gamma photons (173 and 247 keV) in high abundance. This technique has provided a powerful tool to study the in vivo cell kinetics in health and localize abnormal lesions in diseases which invoke intense focal cellular concentration

    2016-04-01

    Non-contact imaging photoplethysmography (iPPG) to detect pulsatile blood microcirculation in tissue has been selected as a successor to low spatial resolution and slow scanning blood perfusion techniques currently employed by clinicians. The proposed iPPG system employs a novel illumination source constructed of multiple high power LEDs with narrow spectral emission, which are temporally modulated and synchronised with a high performance sCMOS sensor. To ensure spectrum stability and prevent thermal wavelength drift due to junction temperature variations, each LED features a custom-designed thermal management system to effectively dissipate generated heat and auto-adjust current flow. The use of a multi-wavelength approach has resulted in simultaneous microvascular perfusion monitoring at various tissue depths, which is an added benefit for specific clinical applications. A synchronous detection algorithm to extract weak photoplethysmographic pulse-waveforms demonstrated robustness and high efficiency when applied to even small regions of 5 mm2. The experimental results showed evidences that the proposed system could achieve noticeable accuracy in blood perfusion monitoring by creating complex amplitude and phase maps for the tissue under examination.

    2016-01-01

    Autologous blood transfusion (ABT) has been gradually attracting more attention due to the increasingly prominent problem of blood transfusion safety and blood shortage in recent years. With the rapid development of blood conservation techniques, blood component separation technology, blood transfusion medicine and a constant increase in clinical needs, ABT technology has been expanded and innovated to a large degree. In this study, the development of preoperative autologous blood donation (PABD), acute normovolemic hemodilution (ANH), intraoperative and postoperative autotransfusion, and other new technologies and theories are reviewed and existing questions are analyzed. Challenges and applications are also discussed in order to provide reference for peers. PMID:27533770

    Application of computation in many fields are growing fast in last two decades. Increasing on computation performance helps researchers to understand natural phenomena in many fields of science and technology including in life sciences. Computational fluid dynamic is one of numerical methods which is very popular used to describe those phenomena. In this paper we propose moving particle semi-implicit (MPS) and molecular dynamics (MD) to describe different phenomena in blood vessel. The effect of increasing the blood pressure on vessel wall will be calculate using MD methods, while the two fluid blending dynamics will be discussed using MPS. Result from the first phenomenon shows that around 80% of constriction on blood vessel make blood vessel increase and will start to leak on vessel wall, while from the second phenomenon the result shows the visualization of two fluids mixture (drugs and blood) influenced by ratio of drugs debit to blood debit.

  11. Exploring the applicability of equine blood to bloodstain pattern analysis.

    Science.gov (United States)

    Larkin, Bethany A J; Banks, Craig E

    2016-07-01

    Bloodstain pattern analysis (BPA) is the forensic application of the interpretation of distinct patterns which blood exhibits during a bloodletting incident, providing key evidence with its ability to map the sequence of events. Here, we explore the use of equine blood and investigate its suitability within the field of BPA. Blood is a complex fluid, and finding a suitable safe substitute to human blood that encompasses all of its characteristics has been the focus of many investigations. Animal blood has been concluded as the closest and therefore the most suitable alternate. However, it seems that currently only porcine blood is most prominently utilised.In this study, equine blood was investigated, using two different anti-clotting methods, where blood impacts were explored over a typical range of varying impact velocities upon a selection of commonly encountered surfaces. Key BPA parameters, such as the diameters of the resulting bloodstains, number of spines and area of origin were measured, which were subsequently applied into previously derived BPA equations.We find that defibrinated equine blood is a suitable alternative and offers the same conclusive outcomes to human blood. This gives bloodstain pattern investigators and researchers an additional choice of blood which can be of benefit when certain bloods are difficult to attain or when the activity involves the usage of a large quantity of blood. Additionally we explore the effect on BPA of aged blood, which revealed a significant decrease in stain diameter of up to 12.78 % when blood has been left for 57 days. A shelf life of no more than 12 days is recommended when blood is refrigerated at 4℃. PMID:25013163

    Blood pool agents remain in the intravascular space for a longer time period. Therefore the optimal imaging window for vascular structures is widened to about 30 minutes. Gadofosveset trisodium (Vasovist, Bayer Schering Pharma AG, Berlin, Germany) is the first blood-pool contrast agent approved in Europe for contrast-enhanced magnetic resonance angiography (MRA) of vessels in the abdomen, pelvis and lower extremity in adults. Other possible applications of blood-pool agents are now being considered, such as assessment of venous thromboembolism, coronary artery disease or sinus venous thrombosis. Perfusion MR imaging holds promise for detecting lung perfusion defects with higher spatial resolution and reduced scan time compared with radionuclide scintigraphy. In coronary artery disease, blood-pool agents enable a substantial increase in the quality of coronary artery imaging. Quantitative myocardial perfusion and myocardial viability seem to be possible, although modifications in protocols and sequence design are necessary for optimal results. Other novel applications of blood-pool agents include monitoring of inflammatory changes in systemic lupus erythematosus and evaluation of tumour invasion into lymph nodes and more reliable assessment of cerebral venous and sinus thrombosis.

    2016-07-01

    Full Text Available Emergency situations, such as accidents, create an immediate, critical need for specific blood type. In addition to emergency requirements, advances in medicine have increased the need for blood in many on-going treatments and elective surgeries. Despite increasing requirements for blood, only about 5% of the Indian population donates blood. In this paper we propose a new and efficient way to overcome such scenarios with our project. We have to create a new idea, just touch the button. Donor will be prompted to enter an individual's details, like name, phone number, and blood type. After that your contact details will appear in alphabetical order on the screen; the urgent time of a blood requirement, you can quickly check for contacts matching a particular or related blood group and reach out to them via Phone Call/SMS through the Blood donor App. Blood Donor App provides list of donors in your city/area. Use this app in case of emergency. A large number of blood donors are attracted using an Android application. Cloud- based services can prove important in emergency blood delivery since they can enable central and immediate access to donors' data and location from anywhere. Since almost everyone carries a mobile phone with him, it ensures instant location tracking and communication. The location-based app, operational on android platform, will help users easily find donors of matching blood groups in their location and access their mobile numbers for instant help. Only a registered person, with willingness to donate blood, will be able to access the service.

  5. Irradiation update: Pork approval could launch major commercial applications

    International Nuclear Information System (INIS)

    In review of recent FDA actions and the probability of FDA issuance of basic food low irradiation dose regulations, a brief discussion considers the possible application of irradiation to fruits and vegetables and how irradiated products might be labelled. Irradiation control insect infestation without the human health risk posed by fumigants and their residues. At low dose levels the sprouting of tubers (potatoes, onions) is inhibited and the ripening of certain fruits is delayed, promoting storage quality and life. At higher doses food pasteurization occurs, destroying microbial pathogens such as Salmonella. Important considerations in selecting the irradiation source include cost, availability, penetrating power, maintenance, and special shielding needs. These and other factors are discussed

    Full Text Available Hypertension is an important manifestation of systemic lupus erythematosus (SLE but reports of prevalence vary between 20-70% in published reports of adult and pediatric patients. For both children and adults with SLE, the clinical diagnosis and management of hypertension has traditionally been based on guidelines developed for the general population. In clinical trials, the criteria used for defining participants with hypertension are mostly undefined. As a first step towards formally assessing the blood pressure (BP patterns of children diagnosed with SLE, 24-hr ambulatory BP monitoring data was analyzed on clinic patients who presented with prehypertension or stage I hypertension. In this pediatric SLE cohort (n=10, 20% met daytime criteria for a diagnosis of hypertension. Patterns of BP elevation varied widely with white coat, masked, isolated systolic, and diastolic nocturnal hypertension all identified. Nocturnal hypertension was detected in 60% and attenuated nocturnal BP dipping in 90% of both hypertensive and normotensive SLE patients. In SLE patients, the median nighttime systolic and diastolic loads were 25% and 15.5% compared with median daily loads of 12.5% and 11.5%. Daytime and nighttime systolic and diastolic BP load and nocturnal dipping was compared to a control population consisting of 85 non-SLE patients under 21 years old with prehypertension or stage 1 hypertension presenting to hypertension clinic. Median systolic BP dipped 5.3 mmHg in SLE patients compared to 11.9 mmHg in non-lupus (p-value = 0.001. Median diastolic BP dipped 12.9 mmHg versus 18.5 mmHg in non-lupus (p-value = 0.003. Patterns of BP dysregulation in pediatric SLE merit further exploration. Children with or without SLE displaying prehypertensive or stage 1 casual BP measurements had similar rates of hypertension by ambulatory BP monitoring. However, regardless of BP diagnosis, and independent of kidney involvement, there was an increased proportion with

  20. 2014 CRL Blood Pressure Study of Life Insurance Applicants.

    Science.gov (United States)

    Fulks, Michael; Dolan, Vera F; Stout, Robert L

    2015-01-01

    Objective .- Define the relative mortality risk by systolic (SBP) and diastolic blood pressure (DBP) in a relatively healthy cohort split by age and sex with adjustment for smoking status, other findings and admitted heart disease history. Method .- Blood pressure (BP in mm Hg), build, laboratory studies and limited medical history are collected when people apply for individual life insurance. Information on 2,472,706 applicants tested by Clinical Reference Laboratory from 1993 to 2007 was utilized with follow-up for vital status using the September 2011 Social Security Death Master File identifying 31,033 deaths. Data was analyzed by SBP and DBP split by age and sex accounting for smoking and for BMI, urine protein/creatinine ratio and history of heart disease in a Cox multivariate survival analysis. Separate analysis by admitted hypertension history was also conducted. Results are presented by SBP and DBP for 4 age-sex groups with and without added covariates beyond age and smoking status. Results .- Relative mortality progressively increased by SBP level from the 90 to 119 band (down to 80 in younger women) upward with little additional impact by DBP. Addition of covariates beyond age and smoking resulted in a 5% to 10% reduction in relative risk. Although high DBP had limited impact, a pulse pressure/SBP ratio >½ identified 1% of applicants at high mortality risk, with little difference in risk for ratios ≤½. Hypertension history with current BP control was associated with a 10% to 25% increase in relative mortality risk as compared to those with similar BP but no such history. Conclusion .- Increasing SBP is closely associated with increasing relative mortality, starting from the lowest SBP. Increasing DBP has little additional impact, but a pulse pressure/SBP ratio >½ is a potent marker of increased risk as well. Accounting for build and other laboratory findings reduces risk modestly. A history of hypertension with current control increases risk.

  1. Department of Health application for approval of construction SP-100 Ground Engineering System Test Site

    Energy Technology Data Exchange (ETDEWEB)

    1990-04-01

    The following Application For Approval of Construction is being submitted by the US Department of Energy-Richland Operations Office, for the SP-100 Ground Engineering System Test Site, which will provide a new source of radioactive emissions to the atmosphere. The US Department of Energy, the National Aeronautics and Space Administration, and the US Department of Defense have entered into an agreement to jointly develop space nuclear reactor power system technology. A ground test of a reactor is necessary to demonstrate technology readiness of this major subsystem before proceeding with the flight system development and demonstration. It is proposed that the SP-100 test reactor be tested in the existing decommissioned Plutonium Recycle Test Reactor containment building (309 Building). The reactor will be operated for at least three months and up to 2 yr. Following the test, the 309 Building will be decontaminated for potential use in other programs. It is projected this new source of emissions will contribute approximately 0.05 mrem/yr dose to the maximally exposed offsite individual. This application is being submitted in response to those projected emissions that would provide the described offsite dose. 28 refs., 9 figs., 7 tabs.

    Nanodiamonds (ND) have emerged to be a widely-discussed nanomaterial for their applications in biological studies and for medical diagnostics and treatment. The potentials have been successfully demonstrated in cellular and tissue models in vitro. For medical applications, further in vivo studies on various applications become important. One of the most challenging possibilities of ND biomedical application is controllable drug delivery and tracing. That usually assumes ND interaction with the blood system. In this work, we study ND interaction with rat blood and analyze how the ND surface modification and coating can optimize the ND interaction with the blood. It was found that adsorption of a low concentration of ND does not affect the oxygenation state of red blood cells (RBC). The obtained in vivo results are compared to the results of in vitro studies of nanodiamond interaction with rat and human blood and blood components, such as red blood cells and blood plasma. An in vivo animal model shows ND injected in blood attach to the RBC membrane and circulate with blood for more than 30 min; and ND do not stimulate an immune response by measurement of proinflammatory cytokine TNF-α with ND injected into mice via the caudal vein. The results further confirm nanodiamonds' safety in organisms, as well as the possibility of their application without complicating the blood's physiological conditions. PMID:27420044

    In this study, a fast and simple blood sampling and sample pre-treatment method based on the use of the dried blood spot (DBS) cards and ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) for the quantification of olive oil phenolic metabolites in human blood was developed and validated. After validation, the method was applied to determine hydroxytyrosol metabolites in human blood samples after the acute intake of an olive oil phenolic extract. Using the FTA DMPK-A DBS card under optimum conditions, with 20µL as the blood solution volume, 100µL of methanol/Milli-Q water (50/50, v/v) as the extraction solvent and 7 disks punched out from the card, the main hydroxytyrosol metabolites (hydroxytyrosol-3-O-sulphate and hydroxytyrosol acetate sulphate) were identified and quantified. The developed methodology allowed detecting and quantifying the generated metabolites at low μM levels. The proposed method is a significant improvement over existing methods to determine phenolic metabolites circulating in blood and plasma samples, thus making blood sampling possible with the volunteer pricking their own finger, and the subsequent storage of the blood in the DBS cards prior to chromatographic analysis.

    Transmission of hepatitis C virus occurs frequently in haemodialysis units. A possible route of transmission is indirectly via the hospital environment although this has never been recorded. We investigated the haemodialysis unit in Deventer Hospital, Deventer, The Netherlands, with the forensic Luminol test. With this test, invisible traces of blood can be visualised based on the principle of biochemiluminescence. We demonstrated extensive contamination of the environment with traces of blood. The aim of this article is to introduce this method to infection control professionals, so it can be used to monitor cleaning and disinfection procedures, and alert healthcare workers to the possibility of contamination of the hospital environment with blood.

  7. Application of ultraviolet irradiation of blood in dermatological practice

    International Nuclear Information System (INIS)

    It is shown that for certain dermatological patients the normalization of vegetative regulation, immunological reactivity and clinical picture is observed only 2-3 months after the course of autotransfusion of UV-irradiated blood. Bearing it in mind, autotransfusion of UV-irradiated blood is recommended for use in dermatological practice. Technical possibilities of the Izolda MD-73M apparatus permit to develop individual approach to the traetment by means of UV-irradiation regime regulation

  11. Application of the Carreau viscosity model to the oscillatory flow in blood vessels

    Science.gov (United States)

    Tabakova, Sonia; Kutev, Nikolay; Radev, Stefan

    2015-11-01

    When studying the oscillatory flow in different types of blood vessels it is very important to know what type of the blood viscosity model has to be used. In general the blood viscosity is defined as a shear-thinning liquid, for which there exist different shear-dependent models, for example the Carreau model, which represents the viscosity as a non-linear function of the shear-rate. In some cases, however, the blood viscosity could be regarded as constant, i.e., the blood is treated as Newtonian fluid. The aim of the present work is to show theoretically and numerically some approximate limits of the Newtonian model application, when the blood vessel is assumed as a 2D straight tube. The obtained results are in agreement with other authors' numerical results based on similar blood viscosity models.

    @@ Almost all clinically important RBC antigens are defined at the molecular level.The expression of protein-and sugar-based antigens on the RBC surface can be predicted by determining the blood group gene variants(alleles).Most of the time,a single nucleotide polymorphism(sNP)distinguishes the allele,which determines an antigen and hence allows predicting the antigen.PCR with sequence specific priming(PCR-SSP)followed by gel electrophoresis was the original technique widely applied for blood group genotyping.Realtime PCR obviated the need for gels.

    Laux, D; Ferrandis, J Y; Brutin, D

    2016-09-01

    During a colloidal droplet evaporation, a sol-gel transition can be observed and is described by the desiccation time τD and the gelation time τG. These characteristic times, which can be linked to viscoelastic properties of the droplet and to its composition, are classically rated by analysis of mass droplet evolution during evaporation. Even if monitoring mass evolution versus time seems straightforward, this approach is very sensitive to environmental conditions (vibrations, air flow…) as mass has to be evaluated very accurately using ultra-sensitive weighing scales. In this study we investigated the potentialities of ultrasonic shear reflectometry to assess τD and τG in a simple and reliable manner. In order to validate this approach, our study has focused on blood droplets evaporation on which a great deal of work has recently been published. Desiccation and gelation times measured with shear ultrasonic reflectometry have been perfectly correlated to values obtained from mass versus time analysis. This ultrasonic method which is not very sensitive to environmental perturbations is therefore very interesting to monitor the drying of blood droplets in a simple manner and is more generally suitable for complex fluid droplets evaporation investigation.

    2014-01-01

    Full Text Available To overcome the issues connected to the use of autologous vascular grafts and artificial materials for reconstruction of small diameter (<6 mm blood vessels, this study aimed to develop acellular matrix- (AM- based vascular grafts. Rat iliac arteries were decellularized by a detergent-enzymatic treatment, whereas endothelial cells (ECs were obtained through enzymatic digestion of rat skin followed by immunomagnetic separation of CD31-positive cells. Sixteen female Lewis rats (8 weeks old received only AM or previously in vitro reendothelialized AM as abdominal aorta interposition grafts (about 1 cm. The detergent-enzymatic treatment completely removed the cellular part of vessels and both MHC class I and class II antigens. One month after surgery, the luminal surface of implanted AMs was partially covered by ECs and several platelets adhered in the areas lacking cell coverage. Intimal hyperplasia, already detected after 1 month, increased at 3 months. On the contrary, all grafts composed by AM and ECs were completely covered at 1 month and their structure was similar to that of native vessels at 3 months. Taken together, our findings show that prostheses composed of AM preseeded with ECs could be a promising approach for the replacement of blood vessels.

    Liu, Yue; Yin, Huijun; Chen, Keji

    2013-11-01

    The development of novel and efficient antiplatelet agents that have few adverse effects and methods that improve antiplatelet resistance has long been the focus of international research on the prevention and treatment of cardiovascular and cerebrovascular diseases. Recent advances in platelet proteomics have provided a technology platform for high-quality research of platelet pathophysiology and the development of new antiplatelet drugs. The study of blood stasis syndrome (BSS) and activated blood circulation of traditional Chinese medicine (TCM) is one of the most active fields where the integration of TCM and western medicine in China has been successful. Activated blood circulation herbs (ABC herbs) of Chinese medicine are often used in the treatment of BSS. Most ABC herbs have antiplatelet and anti-atherosclerosis activity, but knowledge about their targets is lacking. Coronary heart disease (CHD), BSS, and platelet activation are closely related. By screening and identifying activated platelet proteins that are differentially expressed in BSS of CHD, platelet proteomics has helped researchers interpret the antiplatelet mechanism of action of ABC herbs and provided many potential biomarkers for BSS that could be used to evaluate the clinical curative effect of new antiplatelet drugs. In this article the progress of platelet proteomics and its advanced application for research of BSS and ABC herbs of Chinese medicine are reviewed.

    Implantable rotary blood pump (IRBP) has been promoted to the stage of clinical trial. This paper introduces a unique IRBP without a shaft. Instead of using thrombogenic pivots or power-drawing magnetic suspension, impeller is supported hydrodynamically when rotating, by lubrication flows in the thin spaces between itself and the pump body. To this end, the flow is very difficult to be measured using usual laboratory equipments. Therefore, computational fluid dynamics (CFD) has been applied as an important tool in the IRBP design and its validation procedure. Several CFD results such as pump performance improvement, unsteady hydraulic dynamic analysis, biocapability prediction, validation and verification (V&V), and flow visualization have been performed.

    2011-05-01

    We propose and examine a new approach to visualizing a local network of cutaneous blood vessels using laser optical methods for applications in biometry and photomedicine. Various optical schemes of the formation of biometrical information on the architecture of blood vessels of skin tissue are analyzed. We developed an optical model of the interaction of the laser radiation with the biological tissue and a mathematical algorithm of processing of measurement results. We show that, in medicine, the visualization of blood vessels makes it possible to calculate and determine regions of disturbance of blood microcirculation and to control tissue hypoxia, as well as to maintain the local concentration of oxygen at a level necessary for the normal cellular metabolism. We propose noninvasive optical methods for modern photomedicine and biometry for diagnostics and elimination of tissue hypoxia and for personality identification and verification via the pattern of cutaneous blood vessels.

  12. Approval condition in application of bentonite grouting to the radioactive waste disposal

    International Nuclear Information System (INIS)

    The purpose of this study is to understand the flow properties and the permeability of bentonite grout added NaCl by the laboratory tests, and to clarify the approval condition of bentonite as materials. The viscosity of the bentonite suspension was measured under the weight ratio of water and bentonite (W/B) is 6 to 20. The suspension of which W/B is smaller than 10 is difficult to inject into the rock joints, because the viscosity is higher than the thickest cement milk on dam grouting. When the necessary permeability of the clay grout is assumed to be 10-7 (cm/sec), the W/B becomes 10 or less. Then, when we add NaCl to the suspension of which W/B is 6, the viscosity decreases as the amount of NaCl increases. The injectable viscosity is achieved by adding NaCl as the proportion of water to NaCl is 1 to 40. Next, the permeability of the bentonite suspension that added NaCl was examined by the falling head permeability test. It was found that the initial permeability 10-6 (cm/sec) decreased to 10-8∼10-9 (cm/sec) by the test of the sample of 'B:W:NaCl=20:20:1' for 10 days. From these results, the suspension to inject into the rock joints can be made by adding NaCl. And it was clarified that the groundwater permeation to the suspension causes the decrease of the permeability. In addition, the bentonite is swelling according to the infiltration of underground water, the persistence in the suppression effect of diffusion and stability to erosion can be expected. (author)

    2016-08-01

    In this work we present the application of a method for the identification of homologous blood transfusions using forensic genetic techniques based on DNA typing. Ex vivo mixtures of human blood samples - either whole blood or red blood cell concentrates - simulating homologous blood transfusions at different percentages of the donor were typed for a panel of 16 highly variable DNA short tandem repeats (STR). Tested samples included also mixtures, which gave false-negative results if assayed by the reference flow cytofluorimetric method, which is based on the recognition of target antigens located on the membrane of the red blood cell. The recognition of triplets and quadruplets at various loci gave information of the presence of cells belonging to different individuals, as it is the case for homologous blood transfusions. Specificity and sensitivity of the method were assessed in the validation study. The method proved to be unequivocally specific since it was able to recognize all single profiles of each individual, clearly discriminating them from mixtures. Sensitivity resulted as a consequence of the percentage of the donor aliquot in the total volume of the mixture. Although the source of DNA in a blood sample is represented only by nucleated white blood cells, the same procedure resulted effective also in detecting mixtures of red blood cell concentrates (RBCC) from leukodepletion procedure: DNA of the donor from the residual white blood cells resulted still detectable, even if with an expected loss of sensitivity. The proposed approach may contribute to reduce the risk of false-negative results, which may occur using the reference cytofluorimetric method. PMID:27175858

  19. State waste discharge permit application for the 200 Area Effluent Treatment Facility and the State-Approved Land Disposal Site

    Energy Technology Data Exchange (ETDEWEB)

    1993-08-01

    Application is being made for a permit pursuant to Chapter 173--216 of the Washington Administrative Code (WAC), to discharge treated waste water and cooling tower blowdown from the 200 Area Effluent Treatment Facility (ETF) to land at the State-Approved Land Disposal Site (SALDS). The ETF is located in the 200 East Area and the SALDS is located north of the 200 West Area. The ETF is an industrial waste water treatment plant that will initially receive waste water from the following two sources, both located in the 200 Area on the Hanford Site: (1) the Liquid Effluent Retention Facility (LERF) and (2) the 242-A Evaporator. The waste water discharged from these two facilities is process condensate (PC), a by-product of the concentration of waste from DSTs that is performed in the 242-A Evaporator. Because the ETF is designed as a flexible treatment system, other aqueous waste streams generated at the Hanford Site may be considered for treatment at the ETF. The origin of the waste currently contained in the DSTs is explained in Section 2.0. An overview of the concentration of these waste in the 242-A Evaporator is provided in Section 3.0. Section 4.0 describes the LERF, a storage facility for process condensate. Attachment A responds to Section B of the permit application and provides an overview of the processes that generated the wastes, storage of the wastes in double-shell tanks (DST), preliminary treatment in the 242-A Evaporator, and storage at the LERF. Attachment B addresses waste water treatment at the ETF (under construction) and the addition of cooling tower blowdown to the treated waste water prior to disposal at SALDS. Attachment C describes treated waste water disposal at the proposed SALDS.

  2. Associations of methylmercury and inorganic mercury between human cord blood and maternal blood: A meta-analysis and its application

    International Nuclear Information System (INIS)

    Considering the different ability of placental transfer, an assessment of the cord:maternal blood ratio for both methylmercury (MeHg) and inorganic mercury (IHg) is needed especially for interpreting the low-level prenatal exposure. In this study, we conducted a Monte Carlo-based meta-analysis to comprehensively estimate that ratio for MeHg (RMeHg) and IHg (RIHg). The obtained values followed log-normal distributions, with a mean (standard deviation) of 1.89 (0.98) and 1.01 (0.55) for RMeHg and RIHg, respectively. We also estimated the percentage of MeHg in the blood by means of THg in cord and maternal blood using the RMeHg and RIHg, and obtained a value very close to the measured one (relative deviation, −0.4%). In conclusion, the fetus is exposed to approximately twice as much MeHg and to the same level of IHg as in maternal blood; the introduced model provides a rough but reasonable estimate of the percentage of MeHg in the blood. - Highlights: • The cord:maternal blood ratio for methylmerucry was obtained by meta-analyses. • The cord:maternal blood ratio for inorganic mercury was obtained by meta-analyses. • A new model to estimate the percentage of methylmercury in blood was introduced. - The cord:maternal blood ratio distributions and the approach to estimate MeHg percentage in the blood in this paper may provide a new perspective of interpreting prenatal mercury exposure

    Full Text Available Willem J Verberk, Abraham A Kroon, Heidi A Jongen-Vancraybex, Peter W de LeeuwUniversity Hospital Maastricht, Department of Internal Medicine and Cardiovascular Research Institute Maastricht (CARIM, Maastricht University, The NetherlandsPurpose: To review the literature on home blood pressure measurement (HBPM, to examine its validity and applicability for clinical practice and to provide recommendations regarding HBPM assessment.Findings: HBPM can eliminate the white coat effect and offers the possibility to obtain multiple measurements under standardized conditions, which increases knowledge of overall blood pressure value. Although it is not entirely capable of replacing ambulatory blood pressure measurement (ABPM, HBPM correlates better with target organ damage and cardiovascular mortality than office blood pressure measurement (OBPM, it enables prediction of sustained hypertension in patients with borderline hypertension, and proves to be an appropriate tool for assessing drug efficacy. Additional advantages of HBPM are that it may increase drug compliance and patient’s awareness of hypertension. Overall, OBPM yield higher blood pressure values than HBPM. Differences between OBPM and HBPM tend to increase with age and are generally higher in patients without antihypertensive treatment than in patients with antihypertensive treatment.Recommendations: Measurements should be performed according to accepted guidelines and recordings should be performed with a memory equipped automatic validated device. From the data reviewed here, we recommend that HBPM be assessed monthly by taking two measurements in the morning within 1 hour after awakening and two in the evening for three consecutive days, the data from the first day should be dismissed. A subject should be labeled hypertensive if his/her HBPM value is equal to or greater than 137 mmHg systolic and/or 84 mmHg diastolic.Keywords: blood pressure, hypertension, self-measurement, home

  6. Banking of pluripotent adult stem cells as an unlimited source for red blood cell production: potential applications for alloimmunized patients and rare blood challenges.

    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.

    The forensic application of the luminol chemiluminescence reaction is reviewed. Luminol has been effectively employed for more than 40 years for the presumptive detection of bloodstains which are hidden from the naked eye at crime scenes and, for this reason, has been considered one of the most important and well-known assays in the field of forensic sciences. This review provides an historical overview of the forensic use of luminol, and the current understanding of the reaction mechanism with particular reference to the catalysis by blood. Operational use of the luminol reaction, including issues with interferences and the effect of the luminol reaction on subsequent serological and DNA testing is also discussed.

    Shang-zhe XIE; Ning-tao FANG; Shui LIU; Ping ZHOU; Yi ZHANG; Song-mei WANG; Hong-yang GAO; Luan-feng PAN

    2008-01-01

    Background: A major shortcoming in tissue engineered blood vessels (TEBVs) is the lack of healthy and easily attainable smooth muscle cells (SMCs). Smooth muscle progenitor cells (SPCs), especially from peripheral blood, may offer an alternative cell source for tissue engineering involving a less invasive harvesting technique. Methods: SPCs were isolated from 5-ml fresh rat peripheral blood by density-gradient centrifugation and cultured for 3 weeks in endothelial growth medium-2-MV (EGM-2-MV) medium containing platelet-derived growth factor-BB (PDGF BB). Before seeded on the synthesized scaffold, SPC-derived smooth muscle outgrowth cell (SOC) phenotypes were assessed by immuno-fluorescent staining, Western blot analysis, and reverse transcription polymerase chain reaction (RT-PCR). The cells were seeded onto the silk fibroin-modified poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (SF-PHBHHx) scaffolds by 6×104 cells/cm'2 and cultured under the static con-dition for 3 weeks. The growth and proliferation of the seeded cells on the scaffold were analyzed by 3-(4,5-dimethylthiazol-2-yl)-diphenyltetrazolium bromide (MTT) assay, scanning electron microscope (SEM), and 4,6-diamidino-2-phenylindole (DAPI) staining. Results: SOCs displayed specific "hill and valley" morphology, expressed the specific markers of the SMC lineage: protein, and extracellular matrix components elastin and matrix Gla protein (MGP), as well as vascular endothelial growth factor (VEGF). After seeded on the SF-PHBHHx scaffold, the cells showed excellent metabolic activity and proliferation. Conclusion: SPCs isolated from peripheral blood can be differentiated into the SMCs in vitro and have an impressive growth potential in the biodegradable synthesized scaffold. Thus, SPCs may be a promising cell source for constructing TEBVs.

    2015-09-01

    Evolocumab (Repatha™) is a fully human monoclonal antibody developed by Amgen that has been approved as a treatment for hypercholesterolaemia in the EU, and is awaiting approval in the USA and Japan. It specifically binds proprotein convertase subtilisin/kexin type 9 (PCSK9)-a negative regulator of low-density lipoprotein (LDL)-receptors-thereby improving the ability of the liver to bind LDL-cholesterol (LDL-C), leading to reduced LDL-C blood levels. The drug reduces LDL-C levels in patients with hypercholesterolaemia when used as monotherapy or in conjunction with a statin. This article summarizes the milestones in the development of evolocumab leading to this approval for the treatment of adults with primary hypercholesterolaemia (heterozygous familial and non-familial) or mixed dyslipidaemia as an adjunct to diet with or without a statin and/or other lipid lowering therapies, and in adults and adolescents aged ≥12 years with homozygous familial hypercholesterolaemia in combination with other lipid lowering therapies.

    Confidential Unit Exclusion (CUE) refers to a procedure by which a blood donor designates confidentially whether his or her blood might not be safe for transfusion. It applies to situations in which an individual who is not eligible for blood donation in terms of blood safety feel pressured by others to donate his or her blood. A potential problem in the CUE system is misunderstanding of the procedure and its significance by blood donors as well as the lack of their confidence regarding the c...

    Axial flow blood pumps are generally smaller as compared to centrifugal pumps. This is very beneficial because they can provide better anatomical fit in the chest cavity, as well as lower the risk of infection. This article discusses the design, levitated responses, and parameter estimation of the dynamic characteristics of a compact hybrid magnetic bearing (HMB) system for axial flow blood pump applications. The rotor/impeller of the pump is driven by a three-phase permanent magnet brushless and sensorless motor. It is levitated by two HMBs at both ends in five degree of freedom with proportional-integral-derivative controllers, among which four radial directions are actively controlled and one axial direction is passively controlled. The frequency domain parameter estimation technique with statistical analysis is adopted to validate the stiffness and damping coefficients of the HMB system. A specially designed test rig facilitated the estimation of the bearing's coefficients in air-in both the radial and axial directions. Experimental estimation showed that the dynamic characteristics of the HMB system are dominated by the frequency-dependent stiffness coefficients. By injecting a multifrequency excitation force signal onto the rotor through the HMBs, it is noticed in the experimental results the maximum displacement linear operating range is 20% of the static eccentricity with respect to the rotor and stator gap clearance. The actuator gain was also successfully calibrated and may potentially extend the parameter estimation technique developed in the study of identification and monitoring of the pump's dynamic properties under normal operating conditions with fluid.

    Nesfatin is a peptide secreted by peripheral tissues, central and peripheral nervous system. It is involved in the regulation of homeostasis. Although the effects of nesfatin-1 on nutrition have been studied widely in the literature, the mechanisms of nesfatin-1 action and also relations with other physiological parameters are still not clarified well. We aimed to investigate the effect of peripheral chronic nesfatin-1 application on blood pressure regulation in normal and in rats exposed to restraint immobilization stress. In our study, three month-old male Wistar rats were used. Rats were divided into 4 groups as Control, Stress, Control+Nesfatin-1, Nesfatin-1+Stress. Angiotensinogen, angiotensin converting enzyme 2, angiotensin II, endothelin-1, endothelial nitric oxide synthase, aldosterone, cortisol, nesfatin-1 levels were determined in plasma samples by ELISA. Our results have shown that chronic peripheral nesfatin-1 administration increases blood pressure in normal and in rats exposed to chronic restraint stress. Effect of nesfatin-1 on circulating level of angiotensinogen, angiotensin converting enzyme 2, angiotensin II, endothelin-1, endothelial nitric oxide synthase, aldosterone and cortisol has been identified. We can conclude that elevated high blood pressure after chronic peripheral nesfatin-1 administration in rats exposed to chronic restraint stress may be related to decreased plasma level of endothelial nitric oxide synthase concentration.

  7. Applicability of 100 TBq cesium 137 release into environment as a safety criterion for consequence assessment at reactor design approval stage

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency (IAEA) fundamental safety objective is to protect people and the environment from harmful effects of ionizing radiation. Therefore, a severe accident consequence assessment has to be able to include all quantifiable consequences on people and the environment. Our previous studies on estimation of cost per severe accident succeeded in quantifying aforementioned consequences. However, the estimation requires enormous quantity of data, time and human resources, thus it may be inappropriate at the reactor design approval stage. Finnish government uses “100 TBq cesium 137 release into environment”, which was proved to generate limited health effects, as one of the reactor design criteria for accident consequences. In this study, we perform an evaluation of annual dose from the 100 TBq cesium 137 release and confirm limited health effects. We form the environmental impact index based on insights from our previous studies and used it to assess consequences to the environment. The estimated environmental impact index is very small, which confirms the limitedness of the environmental impacts of the release. These findings ensure the applicability of 100 TBq cesium 137 release into environment as a safety criterion for consequence assessment at reactor design approval stage. (author)

    This paper discusses the design and parameter estimation of the dynamics characteristics of a high-speed hybrid magnetic bearings (HMBs) system for axial flow blood pump applications. The rotor/impeller of the pump is driven by a three-phase permanent magnet (PM) brushless and sensorless DC motor. It is levitated by two HMBs at both ends in five-degree-of-freedom with proportional-integral-derivative (PID) controllers; among which four radial directions are actively controlled and one axial direction is passively controlled. Test results show that the rotor can be stably supported to speeds of 14,000 rpm. The frequency domain parameter estimation technique with statistical analysis is adopted to validate the stiffness and damping coefficients of the HMBs system. A specially designed test rig facilitated the estimation of the bearing's coefficients in air—in both the radial and axial directions. The radial stiffness of the HMBs is compared to the Ansoft's Maxwell 2D/3D finite element magnetostatic results. Experimental estimation showed that the dynamics characteristics of the HMBs system are dominated by the frequency-dependent stiffness coefficients. The actuator gain was also successfully calibrated and may potentially extend the parameter estimation technique developed in the study of identification and monitoring of the pump's dynamics properties under normal operating conditions with fluid.

    Objective To determine the chlorpyrifos in human blood by liquid chromatography-tandemmass spectrometry and to validate its application in poisoning cases. Methods The samples were extracted by a simple one-step protein precipitation procedure. Chromatography was performed on a Capcell Pack C18 mG II column (250 mm×2.0 mm, 5μm) using an isocratic elution of solvent A (0.1% formic acid-water with 2 mmol/L ammoniumacetate) and solvent B (methanol with 2 mmol/L ammoniumacetate) at 5∶95 (V∶V).Results The linearranged from5 to 500ng/mL (r=0.9987).Thelimitofdetection (LOD) and the lower limit of quantification (LLOQ ) were 2 ng/mL and 4 ng/mL , respectively. For this method, the precision and accuracy of intra-day and inter-day were <10% and 97.44%-101.10%, respectively. The re-sults in stability test of long-termfrozen were satisfied. The matrix effect, recovery and process efficien-cy were 64.97%-86.81%, 76.70%-85.52%, and 55.57%-66.58%, respectively. Conclusion This method can provide a rapid approach to chlorpyrifos extraction and determination in toxicological analysis of forensic and clinical treatment.

    More than 10 million units of human blood components are processed annually in the United States. Although donor screening and testing have greatly lowered the risk of transmission of viral and protozoan infectious agents, additional sterilization procedures which also preserve blood component function would be of significant value. Use of UV-A and visible-light-range photosensitizers for sterilization of blood platelets and red blood cells, respectively, is currently being aggressively investigated in laboratory-scale optical-mechanical systems. With successful demonstration of the efficacy and safety of these sterilization techniques, implementation in the blood bank setting will require scale-up to optical-mechanical systems capable of handling approximately 25,000 units daily in 500 - 1,000 blood banks in the United States.

    Various commercially available one-step immunoassays for detection of human (primate) blood have been developed. This study evaluated two hemoglobin tests, ABAcard(®) HemaTrace(®) and HemDirect Hemoglobin against glycophorin A test-RSID™-Blood for following parameters: sensitivity, specificity, effectiveness using various substrates, stain remover and aged blood stains. The highest blood detection limit was observed if HemaTrace(®) was used. When compared with HemaTrace(®), ten times lower sensitivity was observed for HemDirect Hemoglobin test. No false positives were obtained for HemDirect Hemoglobin while ABAcard(®) HemaTrace(®), probably due to its extreme sensitivity, showed high percent of false positives with saliva. The lowest sensitivity and 40% of false positives with saliva was exhibited by RSID™-Blood. In addition, this test encountered the lowest efficacy if aged blood-stains or blood treated with stain remover were used. As expected, none of the tested substrates (wood, metal, brick, and soil), influenced on blood testing, although soil substrate affected STR amplification. Conducted studies established HemDirect Hemoglobin test as more reliable for evaluated parameters than ABAcard(®) HemaTrace(®) and RSID™-Blood.

    To research the change characteristics of blood oxygenation content in skeletal muscle, the change regularity between blood oxygenation content and exercise intensity as well as HbO2 and blood lactate acid while taking incremental exercises, we took an in vivo, real-time and continuous measurement on the blood oxygenation content of eight sportsmen when they did incremental exercises of five degrees on a power bicycle using a portable tissue oximeter which is based on the principle of near-infrared spectroscopy(NIRS), simultaneously, we detected the blood lactate acid of subjects after each degree of incremental physical load instantly using a blood lactate analysis equipment. The results showed that the content of HbO2 descended regularly while that of Hb ascended; blood volume decreased; and the density of lactate increased as the intensity of exercises was heightened. The statistics analyses showed that the relationship between HbO2 and blood lactate is rather close (correlation coefficient r=-0.918). With this discovery, a theoretical basis in measuring the relative change of blood oxygenation content non-invasively was evidenced, and a novel technology for assessing the physical situation of sportsman, grasping sports density and evaluating the training effect could be imported.

  15. Estimation of indocyanine green concentration in blood from fluorescence emission: application to hemodynamic assessment during hemodialysis

    There is considerable interest in assessing cardiovascular function noninvasively in patients receiving hemodialysis. A possible approach is to measure the blood concentration of bolus-injected indocyanine green dye and to apply the dye-dilution method for estimating cardiac output and blood volume. Blood ICG concentration can be derived from a measurement of the ICG fluorescence through the dialysis tubing if a simple and unique calibration relationship can be established between transmural fluorescence intensity and blood ICG concentration. We investigated this relationship using Monte Carlo simulations of light transport in blood with varying hematocrit and ICG concentrations and performed empiric measurements of optical absorption and ICG fluorescence emission to confirm our findings. The ICG fluorescence intensity measured at the blood surface, as well as the light intensity remitted by the blood, varied as hematocrit changes modified the absorption and scattering characteristics of the blood. Calibration relationships were developed between fluorescence intensity and ICG concentration that accounted for hematocrit changes. Combining the backreflected fluorescence and the reflected light measured near the point of illumination provided optimal signal intensity, linearity, and robustness to hematocrit changes. These results provide a basis for developing a noninvasive approach to derive optically circulating blood ICG concentration in hemodialysis circuits.

    In this paper, the propagation characteristics of near-infrared (NIR) light in the palm tissue are analyzed,and the principle and feasibility of using transcutaneous diffuse reflectance spectroscopy for non-invasive blood glucose detection are presented. An optical probe suitable for measuring the diffuse reflectance spectrum of human palm and a non-invasive blood glucose detection system using NIR spectroscopy are designed. Based on this system, oral glucose tolerance tests are performed to measure the blood glucose concentrations of two young healthy volunteers. The partial least square calibration model is then constructed by all individual experimental data. The final result shows that correlation coefficients of the two experiments between the predicted blood glucose concentrations and the reference blood glucose concentrations are 0.9870 and 0.9854, respectively. The root mean square errors of prediction of full cross validation are 0.54 and 0.52 mmol/1, respectively.

    Recently, a new tracer for cerebral blood flow (CBF) study; /sup 99m/Tc-labelled-hexamethyl-propyleneamine-oxime (/sup 99m/Tc-HM-PAO) was developed by Amersham international institute. In this paper, we reported the initial experience of tomographic CBF imaging with /sup 99m/Tc-HM-PAO in the comparison of CBF study using positron CT (PET) and 0 approx. 15 labelled CO/sub 2/. Thirty-nine patients with cerebro-vascular disease were examined mainly in the acute phase. All the subjects showed verious disturbances of CBF, which corresponded well to the PET study. However, the image-contrast with /sup 99m/Tc-HM-PAO were inferior to those of the PET study. /sup 99m/Tc-HM-PAO is considered to a good radiopharmaceutical which is readily applicable to eaven an emergency cases.

    A method that relies on subtractive tissue-directed shot-gun proteomics to identify tumor proteins in the blood of a patient newly diagnosed with cancer is described. To avoid analytical and statistical biases caused by physiologic variability of protein expression in the human population, this method was applied on clinical specimens obtained from a single patient diagnosed with nonmetastatic renal cell carcinoma (RCC). The proteomes extracted from tumor, normal adjacent tissue and preoperative plasma were analyzed using 2D-liquid chromatography-mass spectrometry (LC-MS). The lists of identified proteins were filtered to discover proteins that (i) were found in the tumor but not normal tissue, (ii) were identified in matching plasma, and (iii) whose spectral count was higher in tumor tissue than plasma. These filtering criteria resulted in identification of eight tumor proteins in the blood. Subsequent Western-blot analysis confirmed the presence of cadherin-5, cadherin-11, DEAD-box protein-23, and pyruvate kinase in the blood of the patient in the study as well as in the blood of four other patients diagnosed with RCC. These results demonstrate the utility of a combined blood/tissue analysis strategy that permits the detection of tumor proteins in the blood of a patient diagnosed with RCC. PMID:20121140

    Recent technological advancements in the photonics industry have led to a resurgence of interest in optical glucose sensing and to realistic progress toward the development of an optical glucose sensor. Such a sensor has the potential to significantly improve the quality of life for the estimated 16 million diabetics in this country by making routine glucose measurements more convenient. Currently over 100 small companies and universities are working to develop noninvasive or minimally invasive glucose sensing technologies, and optical methods play a large role in these efforts. It has become overwhelmingly clear that frequent monitoring and tight control of blood sugar levels are requisite for effective management of Diabetes mellitus and reduction of the complications associated with this disease. The pain and trouble associated with current "finger-stick" methods for blood glucose monitoring result in decreased patient compliance and a failure to control blood sugar levels. Thus, the development of a convenient noninvasive blood glucose monitor holds the potential to significantly reduce the morbidity and mortality associated with Diabetes. A method and apparatus for noninvasive measurement of blood glucose concentration based on transilluminated laser beam via the Index Finger has been reported in this paper. This method depends on photodiode based laser operating at 632.8 nm wavelength. During measurement, the index finger is inserted into the glucose sensing unit, the transilluminated optical signal is converted into an electrical signal, compared with the reference electrical signal, and the obtained difference signal is processed by signal processing unit which presents the results in the form of blood glucose concentration.

    Since the introduction of visit to visit blood pressure variability (VVBPV) for cardiovascular outcome, it has long been awaited for prospective intervention trial to reduce VVBPV for evidence based medicine. But because of several hurdles, most importantly, pending measure to reduce VVBPV, such trial may not be available in the near future. It means that current understanding on the VVBPV is not casual but related to the cardiovascular outcome.Waiting for more sound evidence, which can be remained in a clinician's mind struggling not to be indifferent for potential benefit? Firstly, the most important potential confounder in spite of the strict statistical analyses to be published may be the mean blood pressure. Secondly, the population candidate for monitoring VVBPV needs to be understood. In general, the higher the risk, the more the value of considering the VVBPV. Thirdly, understanding the biological confounders for VVBPV such as arterial stiffness, low grade systemic inflammation, and sympathetic over-reactivity may inspire the clinician and/or patient the importance of the well-known lifestyle modification such as physical activity. Lastly, therapeutic aspects previously drawing less attention such as the class of drug with less inter-individual blood pressure variability, the relationship between the class of a drug and the volume status, adherence in general, the clinic protocol for the timing of drug intake with or without exercise and office visit, and the general conditions which can affect the volume status and thereby blood pressure level.Even without evidence of direct intervention on VVBPV, by monitoring and understanding VVPBV, a clinician can be developed to a new level of blood pressure management which is not only simply prescribing antihypertensive drugs but also more comprehensive understanding of the patient factors closely related to the blood pressure.

    Noninvasive monitoring of tissue optical properties in real time could significantly improve diagnostics and management of various diseases. Recently we proposed to use high- resolution Optical Coherence Tomography (OCT) technique for measurement of tissue scattering coefficient at the depth of up to 1mm. Our pilot studies performed in vitro and in vivo demonstrated that measurement of tissue scattering with this technique can potentially be applied for noninvasive monitoring of blood glucose concentration. High resolution and coherent photon detection of the OCT technique allowed detection of glucose-induced changes in the scattering coefficient. In this paper we report results of in vivo studies performed in dog, New Zealand rabbits, and first human subjects. OCT system with the wavelength of 1300 nm was used in our experiments. OCT signal slope was measured and compared with actual blood glucose concentration. Bolus glucose injections and glucose clamping administrations were used in animal studies. OCT signals were recorded form human subjects during oral glucose tolerance test. Results obtained form both animal and human studies show good correlation between slope of the OCT signals and actual blood glucose concentration measured using standard glucometesr. Sensitivity and accuracy of blood glucose concentrations monitoring with the OCT is discussed. Obtained result suggest that OCT is a promising technique for noninvasive monitoring of tissue analytes including glucose.

    This paper describes a microsystem for automated blood sampling from laboratory mice used in pharmacokinetic studies. Intended to be mounted as a "backpack" on a mouse, it uses a microneedle, reservoir, and an actuator to instantaneously prick the animal for a time-point sample, eliminating the need for a tethered catheter with large dead volume. The blood is collected by capillary effect through a 31-33 gauge microneedle (250-210 microm OD) into a approximately 1 microL micromachined steel reservoir. The voice coil actuator provides a peak force of approximately 300 mN, which amply exceeds the measured piercing force of mouse skin (i.e., 60-85 mN for a 31-gauge needle with 12 degrees bevel). The sampling system was tested in vitro using a mock vessel with adjustable pressure; the reservoir was filled in electropolishing the inner surface to make it more hydrophilic or using a polymer wire insert to increase the surface area. The steel surface of the reservoir is also coated with silicon oxynitride by plasma-enhanced chemical vapor deposition to improve its hydrophilicity. Blood from fresh bovine tissue was collected into the reservoir to simulate interstitial fluid sampling. In vivo tests on live, anesthetized mice resulted in successful collection of blood into the reservoir. The possible integration of the device in microanalytical systems and the device scalability for multisampling are discussed. PMID:20024028

    Full Text Available To promote the practical application of a Japanese traditional medical treatment, such as hot compresses, we developed a plaster-type warming device consisting of a heat- and steam-generating sheet (HSG sheet. First, we tested its effects when applied to the anterior abdominal wall or lumbar region of women complaining of a tendency towards constipation. Application of the sheet to either region produced a feeling of comfort in the abdomen, as assessed by a survey of the subjects. The significant increases in the total hemoglobin observed in these regions suggested an increase in peripheral blood flow, and significant increases in the HF component on ECG and in the amplitude of gastric motility suggested parasympathetic predominance. We concluded that application of the HSG sheet improves the peripheral hemodynamics and autonomic regulation, induces a feeling of comfort in the abdomen, and provides a beneficial environment for the improvement of gastrointestinal movements.

    Full Text Available Abstract Background Diffuse microvascular bleeding remains a common problem after cardiac procedures. Systemic use of antifibrinolytic reduces the postoperative blood loss. The purpose of this study was to examine the effectiveness of local application of tranexamic acid to reduce blood loss after coronary artery bypass grafting (CABG. Methods Thirty eight patients scheduled for primary isolated coronary artery bypass grafting were included in this double blind, prospective, randomized, placebo controlled study. Tranexamic acid (TA group (19 patients received 1 gram of TA diluted in 100 ml normal saline. Placebo group (19 patients received 100 ml of normal saline only. The solution was purred in the pericardial and mediastinal cavities. Results Both groups were comparable in their baseline demographic and surgical characteristics. During the first 24 hours post-operatively, cumulative blood loss was significantly less in TA group (median of 626 ml compared to Placebo group (median of 1040 ml (P = 0.04. There was no significant difference in the post-op Packed RBCs transfusion between both groups (median of one unit in each (P = 0.82. Significant less platelets transfusion required in TA group (median zero unit than in placebo group (median 2 units (P = 0.03. Apart from re-exploration for excessive surgical bleeding in one patient in TA group, no difference was found in morbidity or mortality between both groups. Conclusion Topical application of tranexamic acid in patients undergoing primary coronary artery bypass grafting led to a significant reduction in postoperative blood loss without adding extra risk to the patient.

    The blood-brain barrier (BBB) is a physiological structure of the blood vessels in the brain. The BBB efficiently traps most therapeutic drugs in the blood vessels and stops them from entering the brain tissue, resulting in a decreased therapeutic efficiency. In this study, we developed BBB-stealth nanocomposites composed of iron oxide (Fe3O4) nanoparticles (NPs) as a safe nanocarrier for glioblastoma therapy. We showed the antitumor activity of Dox/alg-Fe3O4 NPs using in vitro and in vivo tests. We demonstrated that G23-alg-Fe3O4 NPs crossed the BBB and entered the brain. In situ glioblastoma tumor-bearing mice were used to successfully evaluate the antitumor activity of G23-Dox/alg-Fe3O4 NPs. Magnetic resonance imaging (MRI) and bioluminescence imaging (BLI) confirmed the BBB crossing. The BBB-stealth nanocomposites show great potential for a proof-of-concept clinical trial as a theranostics platform for human brain tumor therapy.The blood-brain barrier (BBB) is a physiological structure of the blood vessels in the brain.

    During skeletal muscle contractions, the concentration of ATP increases in muscle interstitial fluid as measured by microdialysis probes. This increase is associated with the magnitude of blood flow, suggesting that interstitial ATP may be important for contraction-induced vasodilation. However......, interstitial ATP has solely been described to induce vasoconstriction in skeletal muscle. To examine whether interstitial ATP induces vasodilation in skeletal muscle and to what extent this vasoactive effect is mediated by formation of nitric oxide (NO) and prostanoids, three different experimental models were...... studied. The rat gluteus maximus skeletal muscle model was used to study changes in local skeletal muscle hemodynamics. Superfused ATP at concentrations found during muscle contractions (1-10 µM) increased blood flow by up to 400%. In this model, the underlying mechanism was also examined by inhibition...

Malignant tumors and viruses have developed, however, strategies to suppress NK cells to escape from their responses.

In some cases these assays require hazardous material such as radioactive isotopes. To overcome these difficulties, we developed a simple assay that uses whole blood instead of PBMC or isolated NK cells. This novel assay is suitable for high-throughput screening and the monitoring of diseases, because it employs serum of ex vivo stimulated whole blood to detect interferon (IFN)-γ secreted from NK cells as an indicator of NKA. After the stimulation of NK cells, the determination of IFNγ concentration in serum samples by enzyme-linked immunosorbent assay (ELISA) provided a swift, uncomplicated, and high-throughput assay of NKA ex vivo.

Therefore, the NKA could be utilized as a supportive diagnostic marker for microsatellite stable (MSS) colorectal cancer.

    Genetic approaches have become an important component of both fundamental and disease-oriented research. Certain diseases of the blood--the hemoglobinopathies--have been elucidated by the spectacular methods of molecular genetics. Some of these advances have already been incorporated in disease management. Often, common conditions such as coronary heart disease and hypertension show familial aggregation. Genetic analysis of these diseases together with biochemical and molecular methods are likely to be useful for further understanding and ultimate prevention and control.

    Understanding the hemodynamics of blood flow in vascular pathologies such as intracranial aneurysms is essential for both their diagnosis and treatment. Computational fluid dynamics (CFD) simulations of blood flow based on patient-individual data are performed to better understand aneurysm initiation and progression and more recently, for predicting treatment success. In virtual stenting, a flow-diverting mesh tube (stent) is modeled inside the reconstructed vasculature and integrated in the simulation. We focus on steady-state simulation and the resulting complex multiparameter data. The blood flow pattern captured therein is assumed to be related to the success of stenting. It is often visualized by a dense and cluttered set of streamlines.We present a fully automatic approach for reducing visual clutter and exposing characteristic flow structures by clustering streamlines and computing cluster representatives. While individual clustering techniques have been applied before to streamlines in 3D flow fields, we contribute a general quantitative and a domain-specific qualitative evaluation of three state-of-the-art techniques. We show that clustering based on streamline geometry as well as on domain-specific streamline attributes contributes to comparing and evaluating different virtual stenting strategies. With our work, we aim at supporting CFD engineers and interventional neuroradiologists.

    2010-04-01

    For similar biological medicinal products, the so-called biosimilars, clinical trials are required rather than just the bioequivalence studies required to support the registration of a generic small molecule drug product. The EU Directive 2001/83/EC, as amended, stated that where a biological medicinal product which is similar to a reference biological product, does not meet the conditions in the definition of generic medicinal products the results of appropriate pre-clinical tests or clinical trials relating to these conditions must be provided. The challenge is to determine the exact nature of the non-clinical and clinical programme required to gain regulatory approval. The applicant is encouraged to provide a detailed description of the strategy used to demonstrate the biosimilar and the reference product have similar profiles in terms of quality, safety and efficacy. The extent to which comparability can be proven will have quite an impact on how many non-clinical and clinical studies the biosimilar applicant will be required to conduct. The dossier submitted by the applicant to the EMEA should cover all aspects of the comparability assessment and must include data on possible unwanted immune reactions to the therapeutic protein. Post-marketing pharmacovigilance plans are also expected to be included in the biosimilar dossier.

    Richard M Martin

    Full Text Available BACKGROUND: In large-scale epidemiology, bloodspot sampling by fingerstick onto filter paper has many advantages, including ease and low costs of collection, processing and transport. We describe the development of an enzyme-linked immunoassay (ELISA for quantifying insulin from dried blood spots and demonstrate its application in a large trial. METHODS: We adapted an existing commercial kit (Mercodia Human Insulin ELISA, 10-1113-01 to quantify insulin from two 3-mm diameter discs (≈6 µL of blood punched from whole blood standards and from trial samples. Paediatricians collected dried blood spots in a follow-up of 13,879 fasted children aged 11.5 years (interquartile range 11.3-11.8 years from 31 trial sites across Belarus. We quantified bloodspot insulin levels and examined their distribution by demography and anthropometry. RESULTS: Mean intra-assay (n = 157 coefficients of variation were 15% and 6% for 'low' (6.7 mU/L and 'high' (23.1 mU/L values, respectively; the respective inter-assay values (n = 33 were 23% and 11%. The intraclass correlation coefficient between 50 paired whole bloodspot versus serum samples, collected simultaneously, was 0.90 (95% confidence interval 0.85 to 0.95. Bloodspot insulin was stable for at least 31 months at -80°C, for one week at +30°C and following four freeze-thaw cycles. Paediatricians collected a median of 8 blood spots from 13,487 (97% children. The geometric mean insulin (log standard deviation concentrations amongst 12,812 children were 3.0 mU/L (1.1 in boys and 4.0 mU/L (1.0 in girls and were positively associated with pubertal stage, measures of central and peripheral adiposity, height and fasting glucose. CONCLUSIONS: Our simple and convenient bloodspot assay is suitable for the measurement of insulin in very small volumes of blood collected on filter paper cards and can be applied to large-scale epidemiology studies of the early-life determinants of circulating insulin.

    Ninety years ago Alexander Fleming (later to discover penicillin) jointly wrote a description of the use of indirect transfusions of citrated blood at a World War 1 (WW1) base hospital. It was the longest series yet to be published, incorporating what was then a novel procedure for treating war casualties. Returning to civilian life Fleming, a qualified surgeon and bacteriologist, chose a different career path, and not until the wars of the late 1930s were the advances in transfusion in WW1 fully incorporated into the management of trauma and haemorrhage. Like penicillin, the benefits of indirect transfusion were only slowly realised.

    The treatment of early-stage tumours decreases the overall mortality of colorectal tumour patients. In this retrospective study we determined the sensitivity and the specificity of the faecal occult blood test (FOBT) and the molecular diagnosis (MD). We analysed 57 stool samples from patients with colorectal carcinomas for the presence of occult blood using a standard FOBT and for alterations in the three different tumour relevant markers APC, BAT26 and L-DNA. Stool samples from 44 control donors were analysed to determine the specificity of the applied methods. Twenty-nine (51%; 95% confidence interval (CI): 38-63%) stool samples of the cancer patients gave positive FOBT results. Thirty-seven (65%; CI: 52-76%) samples showed alterations in at least one DNA marker. Sixteen (28%) samples were positive only in the FOBT, and 24 (42%) samples showed a positive result exclusively in MD. The combined application of both methods resulted in a sensitivity of 93% (CI: 83-97%) and an overall specificity of 89% (CI: 76-95%). The combined application of FOBT and MD resulted in an overall sensitivity, which could not be achieved by any of the methods alone and which is in the range of invasive diagnostic methods.

    2006-02-01

    It is known that glucose interacts with plasma proteins and hemoglobin in erythrocytes. Glycated (glycosylated) hemoglobin is the result of an irreversible non-enzymatic fixation of glucose on the beta chain of hemoglobin A. The amount of glycated hemoglobin depends on blood glucose concentration and reflects the mean glycemia of about the previous 2-3 months. Glycated hemoglobin is a useful marker for long-term glucose control in diabetic patients. Therefore, the search of quick and high sensitive methods for measurement of glycated hemoglobin portion in blood is important. This study is focused on the determination of refractive index of hemoglobin solution at different glucose concentrations. Measurements were performed using Abbe refractometer at 589 nm and optical coherence tomography (OCT) at 820 nm. The different amount of glucose (from 0 to 1000 mg/dl with a step 100 mg/dl) was added to hemoglobin solution. Theoretical values of refractive index of hemoglobin solutions with glucose were calculated supposing non-interacting hemoglobin and glucose molecules. There is a difference between measured and calculated values of refractive index. This difference is due to glucose binding to hemoglobin. It is shown that the refractive index measurements can be applied for the evaluation of glycated hemoglobin amount.

  18. Fluctuations of coupled fluid and solid membranes with application to red blood cells

    Auth, Thorsten; Safran, S. A.; Gov, Nir S.

    2007-11-01

    The fluctuation spectra and the intermembrane interaction of two membranes at a fixed average distance are investigated. Each membrane can either be a fluid or a solid membrane, and in isolation, its fluctuations are described by a bare or a wave-vector-dependent bending modulus, respectively. The membranes interact via their excluded-volume interaction; the average distance is maintained by an external, homogeneous pressure. For strong coupling, the fluctuations can be described by a single, effective membrane that combines the elastic properties. For weak coupling, the fluctuations of the individual, noninteracting membranes are recovered. The case of a composite membrane consisting of one fluid and one solid membrane can serve as a microscopic model for the plasma membrane and cytoskeleton of the red blood cell. We find that, despite the complex microstructure of bilayers and cytoskeletons in a real cell, the fluctuations with wavelengths λ≳400nm are well described by the fluctuations of a single, polymerized membrane (provided that there are no inhomogeneities of the microstructure). The model is applied to the fluctuation data of discocytes (“normal” red blood cells), a stomatocyte, and an echinocyte. The elastic parameters of the membrane and an effective temperature that quantifies active, metabolically driven fluctuations are extracted from the experiments.

    The combined method of hydrogen inhalation and local hydrogen production enable the determination of hepatic blood flow (HBF) and local hepatic blood flow (LHBF). LHBF was registered within a small superficial tissue volume of 0.5 mm in diameter by means of a multi-wire electrode having 200 microns producing and 100 microns measuring wires arranged within less than 300 microns distance between the measuring wires. The feeding current for hydrogen production was 1 microA, the potential less than 10 V. The clearance in response to inhalation was registered by means of the same measuring electrodes within the same tissue volume. Spontaneously breathing rats (Wistar-Frömter strain, 180-230 g bw, N = 19, ketamin-xylazine anesthesia, artificial respiration) showed the following flow values: HBF +/- SD = 0.50 +/- 0.26 ml/g.min, n = 48 registrations; LHBF +/- SD = 4.66 +/- 2.13 ml/g.min, n = 43. The validity of the combined method is demonstrated in the LHBF/HBF graph which summarizes the data of hemorrhagic and control animals, m = 0.1 and yo = 0.001. The correlation coefficient of r = 0.685 shows a reasonable correlation of the combined data despite the wide scattering of the individual values.

    We apply a fully autonomous icequake detection methodology to a single day of high-sample rate (200 Hz) seismic network data recorded from the terminus of Taylor Glacier, ANT that temporally coincided with a brine release episode near Blood Falls (May 13, 2014). We demonstrate a statistically validated procedure to assemble waveforms triggered by icequakes into populations of clusters linked by intra-event waveform similarity. Our processing methodology implements a noise-adaptive power detector coupled with a complete-linkage clustering algorithm and noise-adaptive correlation detector. This detector-chain reveals a population of 20 multiplet sequences that includes ~150 icequakes and produces zero false alarms on the concurrent, diurnally variable noise. Our results are very promising for identifying changes in background seismicity associated with the presence or absence of brine release episodes. We thereby suggest that our methodology could be applied to longer time periods to establish a brine-release monitoring program for Blood Falls that is based on icequake detections.

    Titanium dioxide (TiO2) layers were prepared on a Ti substrate by using oxygen plasma immersion ion implantation (oxygen PIII). The surface chemical states, structure, and morphology of the layers were studied using X-ray photoelectron spectroscopy, X-ray diffraction, Raman microscopy, atomic force microscopy and scanning electron microscope. The mechanical properties, such as the Young's modulus and hardness, of the layers were investigated using nanoindentation testing. The Ti(4+) chemical state was determined to be present on oxygen-PIII-treated surfaces, which consisted of nanocrystalline TiO2 with a rutile structure. Compared with Ti substrates, the oxygen-PIII-treated surfaces exhibited decreased Young's moduli and hardness. Parameters indicating the blood compatibility of the oxygen-PIII-treated surfaces, including the clotting time and platelet adhesion and activation, were studied in vitro. Clotting time assays indicated that the clotting time of oxygen-PIII-treated surfaces was longer than that of the Ti substrate, which was associated with decreased fibrinogen adsorption. In conclusion, the surface characteristics and the blood compatibility of Ti implants can be modified and improved using oxygen PIII. PMID:27524050

    Rapid, point of care (POC) testing has been increasingly deployed as an aid in the diagnosis of infectious disease, due to its ability to deliver rapid, actionable results. In the case of HIV, a number of rapid test devices have been FDA approved and CLIA-waived in order to enable diagnosis of HIV infection outside of traditional laboratory settings. These settings include STD clinics, community outreach centers and mobile testing units, as well as identifying HIV infection among pregnant women and managing occupational exposure to infection. The OraQuick ® rapid test platform has been widely used to identify HIV in POC settings, due to its simplicity, ease of use and the ability to utilize oral fluid as an alternative specimen to blood. More recently, a rapid test for antibodies to hepatitis C virus (HCV) has been developed on the same test platform which uses serum, plasma, finger-stick blood, venous blood and oral fluid. Clinical testing using this POC test device has shown that performance is equivalent to state of the art, laboratory based tests. These devices may be suitable for rapid field testing of blood and other body fluids for the presence of infectious agents.

    We present Defocusing Microscopy (DM), a bright-field optical microscopy technique able to perform total 3D imaging of transparent objects. By total 3D imaging we mean the determination of the actual shapes of the upper and lower surfaces of a phase object. We propose a new methodology using DM and apply it to red blood cells subject to different osmolality conditions: hypotonic, isotonic and hypertonic solutions. For each situation the shape of the upper and lower cell surface-membranes (lipid bilayer/cytoskeleton) are completely recovered, displaying the deformation of RBCs surfaces due to adhesion on the glass-substrate. The axial resolution of our technique allowed us to image surface-membranes separated by distances as small as 300 nm. Finally, we determine volume, superficial area, sphericity index and RBCs refractive index for each osmotic condition.

    Many renal diseases as well as several pharmacons cause a change in renal blood flow and/or renal oxygenation. The blood oxygenation level dependent (BOLD) imaging takes advantage of local field inhomogeneities and is based on a T2{sup *}-weighted sequence. BOLD is a non-invasive method allowing an estimation of the renal, particularly the medullary oxygenation, and an indirect measurement of blood flow without administration of contrast agents. Thus, effects of different drugs on the kidney and various renal diseases can be controlled and observed. This work will provide an overview of the studies carried out so far and identify ways how BOLD can be used in clinical studies. (orig.)

  11. Suppression of fluid membrane fluctuations by a periodic pinning potential: Applications to red blood cells.

    Science.gov (United States)

    Henle, Mark L.; Levine, Alex J.

    2009-03-01

    The membrane of the red blood cell (RBC) is tethered to a two- dimensional triangular network of semi-flexible elastic spectrin filaments. This network allows the cell to maintain its structural integrity during the large shape deformations that occur as it circulates through the microvasculature. The lipid membrane is anchored to the spectrin filaments at the nodes of the network. Consequently, these attachments impose a two-dimensional periodic pinning potential upon the membrane. In this talk, we investigate the effect of this pinning potential on the thermal bending fluctuations of the membrane. We show that there is an exact mapping of this system onto the classic problem of non-interacting electrons subject to a periodic potential; we exploit this mapping to obtain an exact analytic solution for a defect-free triangular array of harmonic pinning sites. The pinning potential affects both the local and global structure of the bending fluctuations. To investigate the local structure we consider the bending correlations between two nearby points in the membrane, while for the global structure we consider the total area stored in the fluctuations. We also investigate the effective area modulus of the membrane/spectrin composite structure.

    During their lifespan, circulating RBC are frequently checked for their deformability. This mechanical quality control operates essentially in the human spleen. RBC unable to squeeze though narrow splenic slits are retained and cleared from the blood circulation. Under physiological conditions this prevents microvessels from being clogged by senescent, rigid RBC. Retention of poorly deformable RBC is an important determinant of pathogenesis in malaria and may also impact the clinical benefit of transfusion. Modulating the splenic retention of RBC has already been proposed to support therapeutic approaches in these research fields. To this aim, the development of microplates for high throughput filtration of RBC through microsphere layers (microplate-based microsphiltration) has been undertaken. This review focuses on potential therapeutic applications provided by this technology in malaria chemotherapy and transfusion. PMID:26138907

    2015-07-01

    The common marmoset (Callithrix jacchus, C. j.) is an established primate model in biomedical research and for human-related diseases. Monitoring of cardiovascular parameters including blood pressure (BP) is important for the health surveillance of these experimental animals and the quantification of diseases or pharmaceutical substances influencing BP. Measurement guidelines for C. j. do not exist yet; therefore, the present study was carried out to establish a practicable protocol based on recommendations of the American College of Veterinary Internal Medicine (ACVIM). Furthermore, BP data of 49 marmosets (13.8-202.4 months of age) were obtained via high-definition oscillometry to further knowledge of physiological parameters and gender-related differences in this primate. The thighs proved to be the most suitable measurement localization, since systolic values were less variable (left 4.03 ± 2.90%, right 5.96 ± 2.77%) compared with the tail (12.7 ± 6.96%). BP values were similar in the morning and in the afternoon (P > 0.05). Data were highly reproducible within and between several sessions on three consecutive days (P > 0.05) as well as over the course of 20 months (P > 0.05). Furthermore, the measurement time for females was significantly shorter than for males (5:14 ± 1:59 min versus 6:50 ± 1:58 min, P = 0.007). Measurement recommendations for the common marmoset were successfully established. Standardized values enabled a reliable comparison of BP parameters, e.g. for cardiovascular, toxicological or metabolic research. PMID:25552521

    2015-06-01

    Full Text Available This paper is focused on Blood Donation Management System which is a web application with supporting mobile application aimed to serve as a communication tool between patients (who need blood and blood donor. To become members of the system, donors need to create their profiles by providing fundamental information like name, blood group, email address, password, and exact location from “Google Map”. In order to find out the exact location of a donor, Google Map is integrated with this application. The mobile application always updates the location of a donor. As a result, the system can automatically find a registered donor wherever he/she goes. Visitors can search blood donors from the home page by blood group and the place where blood is needed. The system will show the available donors along with their phone number, email address and mailing address through arranging them by nearest place and blood donation expire date. Visitors can send message to all donors through email but a member can send message using email and mobile phone. An appointment will be created only whenever a donor confirms that he/she will donate blood. Then the system will alert the donor before 12 hours of donation. Blood donors can also be searched from the mobile application, but this is only accessible for registered members. The goal of this paper is to reduce the complexity of the system to find blood donors in an emergency situation.

    Phenothiazine derivatives are non-antibiotics with antimicrobial, fungistatic and fungicidal effects. We exposed to a high energy UV laser beam phenothiazines solutions in water at 20mg/mL concentration to increase antibacterial activity of resulting mixtures. Compared to previous results obtained on bacteria, more research is needed about UV laser irradiated phenothiazines applications on cancer cell cultures to evidence possible anticancerous properties. Evaluation of the safety of the newly obtained photoproducts in view of use on humans is also needed. Due to expensive animal testing in toxicology and pressure from general public and governments to develop alternatives to in vivo testing, in vitro cell-based models are attractive for preliminary testing of new materials. Cytotoxicity screening reported here shows that laser irradiated (4h exposure time length) chlorpromazine and promazine are more efficient against some cell cultures. Interaction of laser irradiated phenothiazines with fabrics show that promethazine and chlorpromazine have improved wetting properties. Correlation of these two groups of properties shows that chlorpromazine appears to be more recommended for applications on tissues using fabrics as transport vectors. The reported results concern stability study of phenothiazines water solutions to know the time limits within which they are stable and may be used. PMID:26187648

  20. Application of language blood oxygenation level dependent functional MRI in the navigating operation of neurosurgery

    International Nuclear Information System (INIS)

    Objective: To verify the accuracy of blood oxygenation level dependent (BOLD)-based activation using electrocortical stimulation mapping (ESM) and explore the value of language fMRI in the navigating operation of neurosurgery. Methods: In 8 cases with brain tumors, BOLD-fMRI examinations were done before the operations. Under the state of awake anesthesia,the patients were aroused and ESM was conducted. Point-to-point comparison between the BOLD signal activations and the ESM was carried out under the surveillance of the neuro-navigation technology. In order to observe the sensibility and specificity of BOLD activations, the location of BOLD activations and the point of ESM was compared to calculate the stimulating positive points inside the regions of BOLD signals (real positive), outside BOLD regions (pseudo- negative), the stimulating negative points inside the regions of BOLD signals (pseudo-positive), and outside BOLD region (real negative). Two kinds of criteria for assessment were used. One was that the positive stimulating points were located in BOLD regions, and the other was that the positive stimulating points were located within 1 cm around the range of BOLD regions. Removal of the lesions were conducted with the tissue 1 cm around the language region preserved, and the cortex inside 0.5-1.0 cm distance from the positive points were retained. Results: Of the 8 cases, only 6 finished the tasks. Among them, 3 cases were with astrocytoma of grade 2, 2 were with astrocytoma of grade 3, and one with glioblastoma. The total number of stimulating points was 48, among which the positive points were 11. When the first criteria was applied, the sensitivity was 72.7% (8/11), and the specificity was 81.8% (30/37). When the second criteria was applied, the sensitivity was 82.0% (9/11), and the specificity was 75.6% (28/37). Follow-up after operation showed no aphasia occurred. Conclusions: BOLD-fMRI had a high sensitivity and specificity in displaying the language

  2. Biomolecular urease thin films grown by laser techniques for blood diagnostic applications

    International Nuclear Information System (INIS)

    Matrix assisted pulsed laser evaporation (MAPLE) was used for growing urease thin films designed for bio-sensor applications in clinical diagnostics. The targets exposed to laser radiation were made from a frozen composite manufactured by dissolving biomaterials in distilled water. We used a UV KrF* (λ = 248 nm, τFWHM ≅ 30 ns, ν = 10 Hz) excimer source for multipulse laser irradiation of the frozen targets cooled with Peltier elements. The laser source was operated at an incident fluence of 0.4 J/cm2. Urease activity and kinetics were assayed by the Worthington method that monitors urea hydrolysis by coupling ammonia production to a glutamate dehydrogenase reaction. A decrease in absorbance was measured at 340 nm and correlated with the enzymatic activity of urease. We show that the urease films obtained by MAPLE techniques remain active up to three months after deposition.

    Multiple sclerosis (MS) is an autoimmune neurodegenerative disease characterized with immunopathobiological events, including lymphocytic infiltration into the central nervous system (CNS), microglia activation, demyelination and axonal degeneration. Although several neuroprotective drugs have been designed for the treatment of MS, complete remission is yet matter of debate. Therefore, development of novel therapeutic approaches for MS is of a high priority in immunological research. Nanomedicine is a recently developed novel medical field, which is applicable in both diagnosis and treatment of several cancers and autoimmune diseases. Although there is a marked progress in neuroimaging through using nanoparticles, little is known regarding the therapeutic potential of nanomedicine in neurological disorders, particularly MS. Moreover, the majority of data is limited to the MS related animal models. In this review, we will discuss about the brain targeting potential of different nanoparticles as well as the role of nanomedicine in the diagnosis and treatment of MS and its animal model, experimental autoimmune encephalomyelitis.

    Forensic laboratories are often faced with cases in which methamphetamine hydrochloride-mixed blood is unable to be identified as human blood by immunochromatography against human hemoglobin A0. The application of mRNA expression analysis to samples that showed a false-negative with immunochromatography was investigated as an alternative approach that did not depend on the antigen-antibody reaction. Real-time PCR was used to examine the expression levels of blood markers such as glycophorin A, spectrin beta, and hemoglobin beta. Hemoglobin beta was the only marker that was specifically detected in blood, while glycophorin A was useful for determining human specificity. Hemoglobin beta showed good detection sensitivity and was detectable in 37-year-old blood stains. Hemoglobin beta was exclusively detectable in methamphetamine hydrochloride-mixed blood stains. Detergents and disinfectants did not significantly influence mRNA markers. The proposed mRNA expression analysis was suitable for human blood identification as an alternative method to immunochromatography. PMID:27364269

    Equine neutrophil elastase (NE) is a protease released in inflammatory diseases and participating in tissue destruction. To measure NE in horse plasma to assess its role in pathological conditions, we purified elastase from equine neutrophils by a double step chromatography and obtained a pure protein of 27 kDa, 4 kDa smaller than the NE 2A previously purified (Scudamore et al., 1993; Dagleish et al., 1999), which was likely to be NE 2B. We developed an ELISA by using two specific polyclonal antibodies obtained from rabbit and guinea pig. The sandwich complex was detected using a secondary antibody conjugated to alkaline phosphatase. The ELISA showed good precision and accuracy, with intra- and inter-assay coefficients of variation below 10% for equine NE concentrations ranging from 1.875 to 60 ng/ml. A stable plasma NE value, unaffected by the delay of centrifugation (over 4h), was obtained with plasma from EDTA anticoagulated blood. The mean value (+/-SEM) measured in 37 healthy horses was 32.53+/-4.6 ng/ml. NE level in plasma of horses with colic at the time of admission was significantly higher than in healthy horses. Our results indicate that the ELISA technique we developed to measure plasmatic NE is a powerful tool for studying the role of elastase in equine inflammatory disease. In future, the application will be extended to other equine biological fluids. PMID:19932512

    Full Text Available Abstract Background Sub-clinical variant Creutzfeldt-Jakob disease (vCJD infection and reports of vCJD transmission through blood transfusion emphasise the need for blood screening assays to ensure the safety of blood and transplanted tissues. Most assays aim to detect abnormal prion protein (PrPSc, although achieving required sensitivity is a challenge. Methods We have used innovative Atomic Dielectric Resonance Spectroscopy (ADRS, which determines dielectric properties of materials which are established by reflectivity and penetration of radio/micro waves, to analyse blood samples from patients and controls to identify characteristic ADR signatures unique to blood from vCJD and to sCJD patients. Initial sets of blood samples from vCJD, sCJD, non-CJD neurological diseases and normal healthy adults (blood donors were screened as training samples to determine group-specific ADR characteristics, and provided a basis for classification of blinded sets of samples. Results Blood sample groups from vCJD, sCJD, non-CJD neurological diseases and normal healthy adults (blood donors screened by ADRS were classified with 100% specificity and sensitivity, discriminating these by a co-variance expert analysis system. Conclusion ADRS appears capable of recognising and discriminating serum samples from vCJD, sCJD, non-CJD neurological diseases, and normal healthy adults, and might be developed to provide a system for primary screening or confirmatory assay complementary to other screening systems.

    Perfusion-weighted magnetic resonance (MR) imaging using contrast agents plays a key role in characterizing tumors of the brain. We have shown that double-echo perfusion-weighted MR imaging (DEPWI) is potentially useful in assessing brain tumors. Quantitative indices, such as tumor blood volume, are obtained using DEPWI, which allows correction of underestimation of tumor blood volume due to leakage of contrast agents from tumor vessels, in addition to simultaneous acquisition of tumor vessel permeability. This article describes basic concepts of DEPWI and demonstrates clinical applications in brain tumors. (orig.)

    2015-07-01

    We propose the signal processing technique of calculating a cross-correlation function and an average deviation between the continuous blood glucose and the interpolation of limited blood glucose samples to evaluate blood glucose monitoring frequency in a self-aware patient software agent model. The diabetic patient software agent model [1] is a 24-h circadian, self-aware, stochastic model of a diabetic patient's blood glucose levels in a software agent environment. The purpose of this work is to apply a signal processing technique to assist patients and physicians in understanding the extent of a patient's illness using a limited number of blood glucose samples. A second purpose of this work is to determine an appropriate blood glucose monitoring frequency in order to have a minimum number of samples taken that still provide a good understanding of the patient's blood glucose levels. For society in general, the monitoring cost of diabetes is an extremely important issue, and these costs can vary tremendously depending on monitoring approaches and monitoring frequencies. Due to the cost and discomfort associated with blood glucose monitoring, today, patients expect monitoring frequencies specific to their health profile. The proposed method quantitatively assesses various monitoring protocols (from 6 times per day to 1 time per week) in nine predefined categories of patient agents in terms of risk factors of health status and age. Simulation results show that sampling 6 times per day is excessive, and not necessary for understanding the dynamics of the continuous signal in the experiments. In addition, patient agents in certain conditions only need to sample their blood glucose 1 time per week to have a good understanding of the characteristics of their blood glucose. Finally, an evaluation scenario is developed to visualize this concept, in which appropriate monitoring frequencies are shown based on the particular conditions of patient agents. This base line can

    2016-08-01

    Blood alcohol concentration is the most frequent analytical determination carried out in forensic toxicology laboratories worldwide. It is usually required to assess if an offence has been committed by comparing blood alcohol levels with specified legal limits, which can vary widely among countries. Due to possible serious legal consequences associated with non-compliant alcohol levels, measurement uncertainty should be carefully evaluated, along with other metrological aspects which can influence the final result. The whole procedure can be time-consuming and error-generating in routine practice, increasing the risks for unreliable assessments. A software application named Ethanol WorkBook (EtWB) was developed at the author's laboratory by using Visual Basic for Application language and MS Excel(®), with the aim of providing help to forensic analysts involved in blood alcohol determinations. The program can (i) calculate measurement uncertainties and decision limits with different methodologies; (ii) assess compliance to specification limits with a guard-band approach; (iii) manage quality control (QC) data and create control charts for QC samples; (iv) create control maps from real cases data archives; (v) provide laboratory reports with graphical outputs for elaborated data and (vi) create comprehensive searchable case archives. A typical example of drink driving case is presented and discussed to illustrate the importance of a metrological approach for reliable compliance assessment and to demonstrate software application in routine practice. The tool is made freely available to the scientific community at request. PMID:26921868

    The usefulness of a dry-chemistry blood analyzer, Spotchem SP-4410 (SP-4410) in a veterinary clinic for analysis of bovine and equine blood chemistry was studied. We quantitated total protein (TP), albumin (Alb), total bilirubin (T-Bil), blood urea nitrogen (BUN), total cholesterol (T-Cho), glucose (Glu), calcium (Ca), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), creatinine phosphokinase (CPK), and alkaline phosphatase (ALP) in bovine sera. Each sample was assayed with both the SP-4410 and an automated blood analyzer which served as a wet-chemistry reference system, and the data were analyzed with regression analysis. The correlation coefficient for AST was 0.997 being the highest for all the parameters, and all the correlation coefficients were 0.93 or higher. The coefficients of variation were lower than 5.0 except in the case of bovine T-Bil where it was 5,756. The ranges of normal reference values measured by SP-4410 were the same as those reported by other investigators in most cases, but those for GGT and CPK were slightly higher. The strongest interference was observed with hemoglobin. It seems that dry-chemical-analysis of blood serum using the SP-4410 is useful for analysis of bovine and equine blood. PMID:8085395

    Full Text Available Objective To evaluate the stability, safety and efficacy of mobile blood purification system in the treatment of acute renal failure dog model in the field environment. Methods The acute renal failure model was established in 4 dogs by bilateral nephrectomy, which was thereafter treated with the mobile blood purification system. The evaluation of functional index of the mobile blood purification system was performed after a short-time (2 hours and conventional (4 hours dialysis treatment. Results The mobile blood purification system ran stably in the field environment at a blood flow of 150-180ml/min, a dialysate velocity of 2000ml/h, a replacement fluid velocity of 2000ml/h, and ultrafiltration rate of 100-200ml/h. All the functions of alarming system worked well, including static upper limit alarm of ultrafiltration pressure (>100 mmHg, upper limit alarm of ambulatory arterial pressure (>400mmHg, upper limit alarm of ambulatory venous pressure (>400mmHg, bubble alarm of vascular access, bubble alarm during the infusion of solutions, pressure alarm at the substitution pump segment and blood leaking alarm. The vital signs of the 4 dogs with acute renal failure kept stable during the treatment. After the treatment, a remarkable decrease was seen in the levels of serum urea nitrogen, creatinine and serum potassium (P0.05. Conclusions The mobile blood purification system runs normally even in a field environment. It is a flexible and portable device with a great performance in safety and stability in the treatment of acute renal failure. DOI: 10.11855/j.issn.0577-7402.2013.12.15

  1. Application of rapid bedside detection blood NT-proBNP in differential diagnosis of dyspnea in the emergency department

    International Nuclear Information System (INIS)

    Objective: To study rapid bedside detection of NT-proBNP with anti-coagulated venous blood on the significance of differential diagnosis between cardiogenic dyspnea and palmonary dyspnea in emergency room. Methods: 158 patients with dyspnea from our emergency department were divided into cardiogenic group 82 cases, pulmonary group 76 cases and 58 healthy persons as control. All patients within 30 min after hospitalized blood NT-proBNP were measured by rapid bedside technique. Also ultrasonic ECG were examined within 48hr. Results: (1) Blood NT-proBNP level of cardiogenic group (2026.4±122.7 pg/ml): prominently higher than those in controls (P0.05). (2) Cardiogenic group: According to NYHA, grading and staging of CHF, cardias function grade II (n=15), grade III (n=42), grads IV (n=25). Mean level of blood NT-proBNP were 1513, 2598, 4537 pg/ml individually. The concentration of blood NT-proBNP was correlated with severity of CHF. (3) Correlation coefficient of NT-proBNP levels on cardiac function grade II, III, IV and LVEF (left ventricular ejection fraction) were r=0.722 (P<0.05), r=0.615 (P<0.01) and r=0.529 (P<0.01) respectively expressed higher negative correlation. Conclusion: In the case of acute dyspnea, bedside NT-proBNP estimation can be ruled out patients from cardiogenic dyspnea rapidly. The more higher of plasma NT-proBNP combined with ultrasonic ECG indicates between the NT-proBNP level and grading or staging of cardiac function correlated apparently. The more severe of CHF, the more higher of blood NT-proBNP level simultaneously. Detection of blood NT-proBNP concentration may serve as predicator for left ventricles of heart insufficiency.

  3. Scalable parallel methods for monolithic coupling in fluid-structure interaction with application to blood flow modeling

    International Nuclear Information System (INIS)

    We introduce and study numerically a scalable parallel finite element solver for the simulation of blood flow in compliant arteries. The incompressible Navier-Stokes equations are used to model the fluid and coupled to an incompressible linear elastic model for the blood vessel walls. Our method features an unstructured dynamic mesh capable of modeling complicated geometries, an arbitrary Lagrangian-Eulerian framework that allows for large displacements of the moving fluid domain, monolithic coupling between the fluid and structure equations, and fully implicit time discretization. Simulations based on blood vessel geometries derived from patient-specific clinical data are performed on large supercomputers using scalable Newton-Krylov algorithms preconditioned with an overlapping restricted additive Schwarz method that preconditions the entire fluid-structure system together. The algorithm is shown to be robust and scalable for a variety of physical parameters, scaling to hundreds of processors and millions of unknowns.

    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. It is anticipated that when an artificial blood product is available, it will have annual sales of over $7.6 billion in the United States alone.

Hence, partial protein composition of blood serum can be analyzed with microchips even without preliminary removal of proteins of major fractions.

  7. Direct in vivo study of flowing blood-artificial surface interactions - an original application of dynamic isotopic techniques

    International Nuclear Information System (INIS)

    A Ge(Li) detector, associated with a data acquisition and storage unit, and a data analysis facility, was used to record sequentially the activity, related to several radioisotopes, inside an extracorporeal shunt, settled between the femoral artery and the colateral vein of an anaesthetized dog. The shunt was made of a material, the haemocompatibility of which needed to be evaluated. Before the blood was allowed to flow through the shunt, the circulation of the dog was fed with technetium- or indium-labelled biological species thought to be concerned with blood-artificial surface interactions. The method described here offers the possibility of computing kinetic parameters for these interactions. (author)

  8. Application of ICP-OES to determination of barium in blood and urine in clinical and forensic toxicological analysis

    International Nuclear Information System (INIS)

    Complete text of publication follows. Barium compounds are widely employed in many fields; therefore, exposure to this element occurs mostly in the workplace or from drinking water, sometimes from accidental or intentional intoxication (forensic cases). Concentrations of Ba in blood and urine which affect the human health can be rather low. Inductively coupled plasma-optical emission spectrometry (ICP-OES) may turn out to be a reliable sensitive method of determination of Ba for clinical and forensic toxicological purposes. This paper presents a method for Ba determination in blood and urine by ICP-OES after microwave digestion of samples with nitric acid (3 ml) and hydrogen peroxide (1 ml). The overall procedure was checked out by using different spiked blood and urine samples (0.5-5 μg Ba/ml) and standard reference materials (Seronorm Whole Blood L-2, Trace Element Urine). Absolute recovery of the method was 76-104.5% (blood) and 85.1-101.4% (urine), depending strongly on the dilution of the solution after mineralization (matrix effect). The limits of detection and quantification (Ba = 455.4 nm) were: 0.0006 μg Ba/ml and 0.0021 μg Ba/ml, respectively, precision (RSD) - below 6% at the level of 0.015 μg Ba/ml. This method was applied to a clinical case of poisoning of a man in the workplace (contact with powdered BaCO3), probably by inhalation. The concentrations of Ba, in μg/ml, were: 0.165 (blood), 0.460 (serum), 1.458 (urine) on admission to hospital, and 0.0060 (blood), 0.0049 (urine) after 11 months (normal value: <0.001 μg Ba/ml of blood, <0.011 μg Ba/ml of urine). The obtained results show the usefulness of ICP-OES as a method which can be used in clinical and forensic practices.

    In the blood sera of pigs vaccinated with inactivated vaccines manufactured by three different manufacturers the RIA method was used to determine the specific antibodies to the virus of Aujeszky's disease. In certain groups of vaccinated pigs the results of the RIA examination are unfavourably affected by the bond of antibodies to the cellular antigenous determinants. This proves that following vaccination antibodies are formed not only against the viral antigen but also against the antigens of cells on which the vaccination virus is propagated. These shortcomings are eliminated by the use of suitable cellular cultures for the preparation of viral and control antigens. Antigens are applicable for RIA and for ELISA examinations of blood sera of infected and vaccinated pigs. The advantages are described of the RIA and ELISA methods as compared with the virus neutralization test.

    When blood flows through a bifurcation, red blood cells (RBCs) travel into side branches at different hematocrit levels, and it is even possible that all RBCs enter into one branch only, leading to a complete separation of plasma and RBCs. To quantify this phenomenon via particle-based mesoscopic simulations, we developed a general framework for open boundary conditions in multiphase flows that is effective even for high hematocrit levels. The inflow at the inlet is duplicated from a fully developed flow generated in a pilot simulation with periodic boundary conditions. The outflow is controlled by adaptive forces to maintain the flow rate and velocity gradient at fixed values, while the particles leaving the arteriole at the outlet are removed from the system. Upon validation of this approach, we performed systematic 3D simulations to study plasma skimming in arterioles of diameters 20 to 32 microns. For a flow rate ratio 6:1 at the branches, we observed the "all-or-nothing" phenomenon with plasma only entering the low flow rate branch. We then simulated blood-plasma separation in arteriolar bifurcations with different bifurcation angles and same diameter of the daughter branches. Our simulations predict a significant increase in RBC flux through the main daughter branch as the bifurcation angle is increased. Finally, we demonstrated the effectiveness of the new methodology in simulations of blood flow in vessels with multiple inlets and outlets, constructed using an angiogenesis model.

    Full Text Available Abstract Background Since the emergence of next generation sequencing platforms, unprecedented opportunities have arisen in the study of natural vertebrate populations. In particular, insights into the genetic and epigenetic mechanisms of adaptation can be revealed through study of the expression profiles of genes. However, as a pre-requisite to expression profiling, care must be taken in RNA preparation as factors like DNA contamination, RNA integrity or transcript abundance can affect downstream applications. Here, we evaluated five commonly used RNA extraction methods using whole blood sampled under varying conditions from 20 wild carnivores. Results Despite the use of minute starting volumes, all methods produced quantifiable RNA extracts (1.4 – 18.4 μg with varying integrity (RIN 4.6 - 7.7, the latter being significantly affected by the storage and extraction method used. We observed a significant overall effect of the extraction method on DNA contamination. One particular extraction method, the LeukoLOCK™ filter system, yielded high RNA integrity along with low DNA contamination and efficient depletion of hemoglobin transcripts highly abundant in whole blood. In a proof of concept sequencing experiment, we found globin RNA transcripts to occupy up to ¼ of all sequencing reads if libraries were not depleted of hemoglobin prior to sequencing. Conclusion By carefully choosing the appropriate RNA extraction method, whole blood can become a valuable source for high-throughput applications like expression arrays or transcriptome sequencing from natural populations. Additionally, candidate genes showing signs of selection could subsequently be genotyped in large population samples using whole blood as a source for RNA without harming individuals from rare or endangered species.

    Ripasudil hydrochloride hydrate (Glanatec® ophthalmic solution 0.4 %; hereafter referred to as ripasudil) is a small-molecule, Rho-associated kinase inhibitor developed by Kowa Company, Ltd. for the treatment of glaucoma and ocular hypertension. This compound, which was originally discovered by D. Western Therapeutics Institute, Inc., reduces intraocular pressure (IOP) by directly acting on the trabecular meshwork, thereby increasing conventional outflow through the Schlemm's canal. As a result of this mechanism of action, ripasudil may offer additive effects in the treatment of glaucoma and ocular hypertension when used in combination with agents such as prostaglandin analogues (which increase uveoscleral outflow) and β blockers (which reduce aqueous production). The eye drop product has been approved in Japan for the twice-daily treatment of glaucoma and ocular hypertension, when other therapeutic agents are not effective or cannot be administered. Phase II study is underway for the treatment of diabetic retinopathy. This article summarises the milestones in the development of ripasudil leading to the first approval for glaucoma and ocular hypertension. PMID:25414122

    Given that self-efficacy has emerged as a key construct in health psychology, this study set out to explore its utility in the context of blood donation as defined within the Theory of Planned Behaviour (TPB). An Ajzen and Fishbein-type questionnaire was administered to 100 undergraduate students at the University of Ulster, Coleraine. A hierarchical multiple regression analysis provided strong support for the role of self-efficacy as a major determinant of intention. It not only helped to explain some 73% of the variance, but also made a greater contribution to the prediction of intention than the other main independent variables of the model-past behaviour and self-identity. Demonstrating the utility of self-efficacy in the context of blood donor behaviour not only has several important practical implications, but serves to further highlight its importance within the TPB.

    Full Text Available Aim: Isolation, dark field detection and microscopic agglutination test (MAT are considered ―gold standard‖ tests for diagnosis of Leptospirosis. Several PCR assays are reported but very few have been evaluated for detection of Leptospirosis. Therefore, this study was undertaken. This study aims to design and standardize polymerase chain reaction (PCR - based DNA sequencing technique for the detection of pathogenic Leptospira from peripheral blood of patients clinically diagnosed with septicemia. Methodology and Results: Two hundred and seven (207 blood samples from patients were diagnosed with septicemia which includes 100 bacterial (other than Leptospira culture positive and 107 bacterial culture negative samples were studied. Primers for Nested PCR targeting LipL32 gene of Leptospira interrogans were designed and the specificity of primers was tested against serum samples positive/negative by either MAT or dark field microscopy. PCR amplified products were further confirmed by DNA sequencing. The standardized nPCR was sensitive and specific to Leptospira interrogans. Twenty-one (21% out of 100 culture positive blood samples, three (2.8% out of 107 culture negative samples showed nPCR positivity and were confirmed as Leptospira interrogans by DNA sequencing (p<0.001. A sensitive nPCR specific to Leptospira interrogans was developed. Conclusion, significance and impact of study: The p value (<0.001 signifies that Leptospira is commonly associated with other bacteria circulating in blood indicating that a decreased immune status is created primarily by a bacterium with enhanced possibility of development of Leptospiral infection probably be of an endogenous origin.

    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.

    AIM: To investigate the effectiveness and safety of recombinant human growth hormone (rhGH) in postoperative patients.METHODS: A total of 48 consecutive patients undergoing abdominal operations were randomized to receive either subcutaneous rhGH (0.15 IU/kg) or placebo (menstruum) injections daily for 7 d after surgery. The two groups had similar nutritional intake. Blood samples for serum fibronectin, albumin, prealbumin, transferrin and the total lymphocyte count, as well as glucose levels were collected to study the rhGH effect. Basal laboratory evaluation, and nutritional status were estimated on d 1before as baseline and d 3 and 10 after operation using standard laboratory techniques. Nitrogen balance was measured from d 3 to 9 after operation.RESULTS: The cumulative nitrogen balance was significantly improved in rhGH group compared with the placebo group (11.37±16.82 vs -9.11±17.52, P = 0.0003).Serum fibronectin was also significantly higher in the rhGH group than in the placebo group (104.77±19.94vs 93.03±16.03, P<0.05), whereas changes in serum albumin, prealbumin, transferrin and total lymphocyte counts were not statistically significant. Mean blood glucose levels were significantly higher in the rhGH group from d 3 to 6 after operation.CONCLUSION: If blood glucose can be controlled, lowdose growth hormone together with hypocaloric nutrition is effective on improving positive nitrogen balance and protein conservation and safe is in postoperative patients.

  6. Application for approval of derived authorized limits for the release of the 190-C trenches and 105-C process water tunnels at the Hanford Site: Volume 2 - Source term development

    International Nuclear Information System (INIS)

    As part of environmental restoration activities at the Hanford Site, Bechtel Hanford, Inc. (BHI) is conducting a series of evaluations to determine appropriate release conditions for specific facilities following the completion of decontamination and decommissioning (D and D) projects. The release conditions, with respect to the residual volumetric radioactive contamination, are termed authorized limits. This two volume report provides the necessary evaluations for the 290-C trenches and 105-C process water tunnels, and is intended to serve as the technical basis for a request for approval of authorized limits of residual radioactive contamination levels associated with these facilities. Volume 2 contains the Source Term Determination. This volume contains the radiological characterization data, spreadsheet analyses, and results of efforts to determine the radiological source terms. The source terms characterize the radionuclides and activity concentration levels for the facilities, and serves as input to the various radiation exposure pathways and scenarios used to estimate the individual radiation doses that could result from release of these facilities. Based on the results of these evaluations, it is determined that the application of the proposed authorized limits for the 190-C trenches and the 105-C process water tunnels represents a safe and cost-effective approach to their final disposition

    An improved RIA for measurement of oxytocin in blood is described by using an extraction method with SEP-PAK C/sub 18/ cartridges, which allows also concentration of the sample, a new antiserum with a higher sensitivity to standard oxytocin and preparation of the standard curve in buffer. The lower limit of assay sensitivity was 0.25 pg/tube, corresponding to 0.25-1.0 pg/ml plasma depending on the amount of plasma extracted. Hence, it was no problem to measure oxytocin basal concentrations in peripheral blood in the range of 0.6-4 pg/ml plasma depending on the stage of the oestrous cycle. The highest oxytocin concentrations occurred during the early and mid-luteal phase. The method has been applied also for samples from women, sheep, pigs and horses. Mean (+-SD) recovery of oxytocin added to plasma or only buffer after extraction was 71.3+-8,1%, and the coefficient of variation (CV) = 11.4% (n = 27 assays). The intra-assay CV of two control samples was 7.9+-2.8 and 7.8+-2.4% (n = 17 assays). The inter-assay CV of 5 control samples with low and high oxytocin concentrations varied between 10.8+-17.3% (n = 25 assays). The 50% intercept was 2.5+-0.3 pg, CV = 11.3% (n = 29 assays).

    A substantial proportion (44%) of traffic injury cases seeking emergency services in public hospitals had a blood alcohol concentration (BAC) of 0.1 per cent or more. To reduce alcohol related traffic injuries and deaths, a law was enacted setting a criminal per se legal blood alcohol limit at 0.05 per cent in 1994. However, not until 1997, was an active public education program undertaken on a national scale to raise awareness against drink driving and to support law enforcement. This includes dissemination of knowledge through multiple channels e.g., roadside posters; stickers on the back of vehicles; sporadic radio and TV programs or spots; public announcements; press reports. In 1999, highly visible sobriety check points were set up as a measure for law enforcement. In order to systematically assess the campaign, multiple methods were used to collect relevant data. This report focused on the outcomes of the campaign based on hospital surveillance data in the emergency rooms of 4 public hospitals from March to November, 2000 on alternate months. It was found that the campaign succeeded in raising public awareness and support for law enforcement against drink driving. However, the proportion of road victims with illegal BAC seeking emergency care did not decline after 17 months of the campaign. Limitations and weaknesses of law enforcement activities were discussed along with recommendation for future action. PMID:12118498

  12. New radioisotope method for the investigation of uteroplacental blood flow and its application in pregnancies with retarded intrauterine growth

    International Nuclear Information System (INIS)

    A new radioisotope technique was developed applying sup(99m)Tc-pertechnetate in order to measure placental blood flow for early detection of placental insufficiency. Using this method placental perfusion was measured in 20 healthy pregnancies and in 26 ones complicated with intrauterine growth retardation. The T-maximum pictures obtained made it possible to differentiate between the vascular and intervillous phases of placental blood flow. The time period of intervillous phase calculated as the percent of the whole placental T-maximum was given as intervillous perfusion index (IPI). It was demonstrated that IPI is significantly longer in pregnancies complicated with intrauterine growth retardation (66.2+-14.6) than that of the control group (31.6+-10.7). Regarding the individual cases, IPI values were higher than 50% in the former and lower than 50% in the latter group. These data suggest that the first sign of placental insufficiency is the prolongation of IPI, which is likely to precede the quantitative reduction of placental perfusion. (author)

    Guaifenesin is an expectorant used to improve mucociliary clearance (MCC) and relieve chest congestion from upper respiratory tract infections. Immediate-release (IR) guaifenesin requires dosing every 4 hours to maintain efficacy because of the drug's short half-life. Extended-release (ER) guaifenesin has been developed to prolong efficacy and reduce dosing frequency. As part of the 505(b)(2) new drug application (NDA), the pharmacokinetics (PK) of an ER bi-layer tablet formulation of guaifenesin (Mucinex®) and bioequivalence to an over-the-counter (OTC) monograph IR formulation were evaluated in healthy subjects. In one study, subjects received 1,200 mg ER guaifenesin every 12 hours or 400 mg IR guaifenesin every 4 hours for 6 days. Steady-state exposures were equivalent between the two products, as demonstrated by AUC and Cmax . In another study, subjects received a single dose of 600 mg (fasted) or 1,200 mg (fasted or fed) ER bi-layer tablet formulations. AUC and Cmax were equivalent between both states for the 1,200 mg ER dose. However, Tmax of 1,200 mg ER guaifenesin was later in the fed than the fasted state. ER guaifenesin is bioequivalent to corresponding OTC monograph doses of IR guaifenesin. ER guaifenesin offers a convenient 12-hour dosing alternative to 4-hour dosing of IR guaifenesin.

    The lack of clinical laboratory tests is a major obstacle in the reliable diagnosis and quantitative treatment assessment and prevention of psychiatric disorders and in the development of patient-centric psychiatric practices. Optical topography has been approved as an insurance-covered auxiliary laboratory test for differential diagnosis of depressive state by Ministry of Health, Labour and Welfare in Japan since 2014. Near-infrared spectroscopy (NIRS), theoretical basis of optical topography, is one of functional neuroimaging techniques that has been increasingly employed in psychology and psychiatry. Because NIRS can detect only cerebral cortex reactivities with low spatial resolution and may suffer from contaminating signals from skin and skull, its data should be interpreted as a global index of cerebral cortex reactivities. Within these limitations, the advantages of NIRS over fMRI such as complete non-invasiveness, small measurement apparatus, high time resolution, and natural examination setting lead it to one of the preferred methods in studies of brain substrates of psychiatric disorders. Two-thirds of the original articles on NIRS application in psychiatry have been published by Japanese researchers. NIRS examination of major depressive disorder, bipolar disorder, and schizophrenia using a verbal fluency task of only three minutes demonstrated diagnosis-specific characteristics of frontal lobe function. These characteristics have been established as suggesting potential diagnosis of bipolar disorder or schizophrenia in clinically diagnosed major depressive disorder. In order to establish the application of NIRS as clinically useful laboratory tests in psychiatry, auxiliary nature of NIRS examination for differential diagnosis should be properly recognized both by patients and psychiatrists.

  17. Effects of short-term application of low-dose growth hormone on trace element metabolism and blood glucose in surgical patients

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    AIM: To investigate the effects of short-term application of low-dose growth hormone on trace element metabolism and blood glucose in surgical patientsMETHODS: A total of 48 consecutive patients undergoing abdominal operations were randomized to receive either subcutaneous rhGH (0.15 IU/kg) or placebo (menstruum) injections daily for 7 d after surgery. The two groups had similar nutrition intake.Blood, feces, urine and drain samples were collected to measure zincum, cuprum and ferrum as well as glucose levels. Accumulative intake, excretion and balance of zincum, cuprum and ferrum, apparent absorption (AA)and apparent utilization (AU) of zincum, cuprum and ferrum, blood glucose levels and adverse events were estimated.RESULTS: There were no differences in accumulative intake and drain excretion between the two groups.The feces excretion and accumulative excretion of cuprum were lower in the rhGH group (P < 0.05). The urinary excretion of zincum, cuprum and ferrum was all significantly decreased in the rhGH group (P < 0.05)and the accumulative balance of zincum, cuprum and ferrum was improved compared with the placebo group (P < 0.05). AA of cuprum in the rhGH group was almost twice as much as the placebo group (P < 0.05), and AU of zincum, cuprum and ferrum was all improved in the rhGH group (P < 0.05). The mean blood glucose level was significantly higher in the rhGH group than in the placebo group from d 3 to d 6 after operation (P < 0.05).CONCLUSION: Postoperative low-dose rhGH treatment improves the retention of zincum, cuprum and ferrum and decreases the excretion of zincum, cuprum and ferrum, improves the balance of zincum, cuprum and ferrum, and promotes the AA and AU of zincum,cuprum and ferrum. rhGH can be well tolerated without significant adverse effects and the blood glucose level can be well controlled.

    Full Text Available Miniaturization of imaging systems can significantly benefit clinical diagnosis in challenging environments, where access to physicians and good equipment can be limited. Sub-pixel resolving optofluidic microscope (SROFM offers high-resolution imaging in the form of an on-chip device, with the combination of microfluidics and inexpensive CMOS image sensors. In this work, we report on the implementation of color SROFM prototypes with a demonstrated optical resolution of 0.66 µm at their highest acuity. We applied the prototypes to perform color imaging of red blood cells (RBCs infected with Plasmodium falciparum, a particularly harmful type of malaria parasites and one of the major causes of death in the developing world.

  1. Electroosmotic oscillatory flow of micropolar fluid in microchannels:application to dynamics of blood flow in microfluidic devices

    JC MISRA; S CHANDRA; GC SHIT; PK KUNDU

    2014-01-01

    The electroosmotic flow of a micropolar fluid in a microchannel bounded by two parallel porous plates undergoing periodic vibration is studied. The equations for conservation of linear and angular momentums and Gauss’s law of charge distribution are solved within the framework of the Debye-H¨uckel approximation. The fluid velocity and microrotation are assumed to depend linearly on the Reynolds number. The study shows that the amplitude of microrotation is highly sensitive to the changes in the magnitude of the suction velocity and the width of the microchannel. An increase in the micropolar parameter gives rise to a decrease in the amplitude of microrotation. Numerical estimates reveal that the microrotation of the suspended microelements in blood also plays an important role in controlling the electro-osmotically actuated flow dynamics in micro-bio-fluidic devices.

    Due to limited remote triage monitoring capabilities, combat medics cannot currently distinguish bleeding soldiers from those engaged in combat unless they have physical access to them. The purpose of this study was to test the hypothesis that low-level physiological signals can be used to develop a machine-learning algorithm for tracking changes in central blood volume that will subsequently distinguish central hypovolemia from physical activity. Twenty-four subjects underwent central hypovolemia via lower body negative pressure (LBNP), and a supine-cycle exercise protocol. Exercise workloads were determined by matching heart rate responses from each LBNP level. Heart rate and stroke volume (SV) were measured via Finometer. ECG, heat flux, skin temperature, galvanic skin response, and two-axis acceleration were obtained from an armband (SenseWear Pro2) and used to develop a machine-learning algorithm to predict changes in SV as an index of central blood volume under both conditions. The algorithm SV was retrospectively compared against Finometer SV. A model was developed to determine whether unknown data points could be correctly classified into these two conditions using leave-one-out cross-validation. Algorithm vs. Finometer SV values were strongly correlated for LBNP in individual subjects (mean r = 0.92; range 0.75-0.98), but only moderately correlated for exercise (mean r = 0.50; range -0.23-0.87). From the first level of LBNP/exercise, the machine-learning algorithm was able to distinguish between LBNP and exercise with high accuracy, sensitivity, and specificity (all ≥90%). In conclusion, a machine-learning algorithm developed from low-level physiological signals could reliably distinguish central hypovolemia from exercise, indicating that this device could provide battlefield remote triage capabilities.

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....

    How can you, as an acquisition librarians, keep current on the output of hundreds of publishers? The answer, of course, is that you cannot. For over 30 years, approval plans have been used by librarians to acquire current titles, save staff time, and build core collections. Even today, these reasons seem appropriate, as libraries try to maintain up-to-date collections and control personnel and operating budgets. However, as shown in Approval Plans: Issues and Innovations, the use of approval plans is not so simple and straightforward; their use is subject to complex procedures and policies--an

    2015-12-01

    Full Text Available Celiac disease (CD is a common lifelong food intolerance triggered by dietary gluten affecting 1% of the general population. Gliadin-specific T-cell lines and T-cell clones obtained from intestinal biopsies have provided great support in the investigation of immuno-pathogenesis of CD. In the early 2000 a new in vivo, less invasive, approach was established aimed to evaluate the adaptive gliadin-specific T-cell response in peripheral blood of celiac patients on a gluten free diet. In fact, it has been demonstrated that three days of ingestion of wheat-containing food induces the mobilization of memory T lymphocytes reactive against gliadin from gut-associated lymphoid tissue into peripheral blood of CD patients. Such antigen-specific T-cells releasing interferon-γ can be transiently detected by using the enzyme-linked immunospot (ELISPOT assays or by flow cytometry tetramer technology. This paper discusses the suitability of this in vivo tool to investigate the repertoire of gluten pathogenic peptides, to support CD diagnosis, and to assess the efficacy of novel therapeutic strategies. A systematic review of all potential applications of short oral gluten challenge is provided.

    Paper spray mass spectrometry has been demonstrated to be promising for direct analysis of therapeutic drugs in dried blood spots (DBS); however, the strong hydrogen bond and van de Waals interactions between paper substrate and analytes containing polar functional groups (e.g., therapeutic drugs) affect greatly the elution behavior and analysis sensitivity of compounds of interest during paper spray. Herein, we developed a one-sided ZrO2 coated paper substrate through a facile vacuum filtration approach using commercial ZrO2 particles as coating material and soluble starch as adhesive agent. Owing to the unique surface properties, as-prepared ZrO2 paper substrate has been shown to have excellent performance for analysis of therapeutic drugs in DBS during paper spray mass spectrometry. In contrast to original cellulose paper substrates, improvements of 43-189-fold in lower limit of quantitation (LLOQ) were obtained for the tested drugs using ZrO2 coated paper for paper spray. In comparing with the previously reported grade SG81 paper and one-sided silica coated paper, the LLOQs of the tested drugs with as-prepared ZrO2 paper decreased 1.5-16.5-fold relative to those from the above two, revealing that ZrO2 coated paper is a good candidate for paper spray in high sensitivity analysis of therapeutic drugs in DBS.

    The hemocompatibility of silk fibroin (SF) was improved with ferulic acid (FA) by graft polymerization. Ferulic acid is an active ingredient of many Chinese herbal medicines, such as Chuanxiong (Rhizoma ligustici wallichii), Danggui (Angelica sinensis) and Awei (Asafoetida giantfennel), which have been used to treat cardiovascular diseases by Chinese physicians for thousands of years. The inhibitory functions of FA on blood coagulation and erythrocyte agglutination were first characterized by a Lee-White test tube method and a micropipette technique, respectively. Then, FA was immobilized on SF by graft polymerization and the surface composition of modified SF was characterized by attenuated total reflectance Fourier-transform infrared (ATR-FTIR), x-ray photoelectron spectroscopy (XPS) and optical microscopy. The anticoagulant activity of modified SF was assessed, respectively, by in vitro clotting time measurements on a photo-optical clot detection instrument and with the Lee-White test tube method. The test results indicated that in comparison to untreated SF, the anticoagulant activity of modified SF has been improved significantly. Moreover, the SF surface composition is altered by FA but its {beta}-sheet conformation is not disturbed.

    2005-05-01

    Full Text Available Abstract Background Cell simulation, which aims to predict the complex and dynamic behavior of living cells, is becoming a valuable tool. In silico models of human red blood cell (RBC metabolism have been developed by several laboratories. An RBC model using the E-Cell simulation system has been developed. This prototype model consists of three major metabolic pathways, namely, the glycolytic pathway, the pentose phosphate pathway and the nucleotide metabolic pathway. Like the previous model by Joshi and Palsson, it also models physical effects such as osmotic balance. This model was used here to reconstruct the pathology arising from hereditary glucose-6-phosphate dehydrogenase (G6PD deficiency, which is the most common deficiency in human RBC. Results Since the prototype model could not reproduce the state of G6PD deficiency, the model was modified to include a pathway for de novo glutathione synthesis and a glutathione disulfide (GSSG export system. The de novo glutathione (GSH synthesis pathway was found to compensate partially for the lowered GSH concentrations resulting from G6PD deficiency, with the result that GSSG could be maintained at a very low concentration due to the active export system. Conclusion The results of the simulation were consistent with the estimated situation of real G6PD-deficient cells. These results suggest that the de novo glutathione synthesis pathway and the GSSG export system play an important role in alleviating the consequences of G6PD deficiency.

    Full Text Available To date, the Ghanaian development control system has proven unsuccessful in delivering quality planning application approvals in a timely manner and it is doubtful whether it is possible to achieve that basic goal in its current form. Planning application approval assessment is performed conjointly by various planning organizations spearheaded by Accra Town and Country Planning Department (TCPD. The success in delivering quality approvals in a timely manner therefore depends on the inter-organizational task interdependency, collaboration, and teamwork of the various planning agencies that form the Accra Metropolitan Assembly. The paper puts into perspective the TCPD organizational workflow and knowledge flow based on their strategies, size, leadership style, organizational complexities, and their competencies to contribute to the success of the approval process. Further, this paper examines the reasons behind the increasing amorphous planning and unapproved development/construction and identifies the various planning approval problems. Finally, it offers modalities to curtail planning approval delays.

    2014-02-01

    This paper introduces a hedge operator based fuzzy divergence measure and its application in segmentation of leukocytes in case of chronic myelogenous leukemia using light microscopic images of peripheral blood smears. The concept of modified discrimination measure is applied to develop the measure of divergence based on Shannon exponential entropy and Yager's measure of entropy. These two measures of divergence are compared with the existing literatures and validated by ground truth images. Finally, it is found that hedge operator based divergence measure using Yager's entropy achieves better segmentation accuracy i.e., 98.29% for normal and 98.15% for chronic myelogenous leukocytes. Furthermore, Jaccard index has been performed to compare the segmented image with ground truth ones where it is found that that the proposed scheme leads to higher Jaccard index (0.39 for normal, 0.24 for chronic myelogenous leukemia).

    In this paper an endovascular measurement system used for intraoperative cerebral blood flow monitoring is described. The system is based on a Volcano ComboMap Pressure and Flow System extended with analogue-to-digital converter and PC laptop. A series of measurements performed in patients with cerebrovascular pathologies allows us to introduce “velocity-pressure” and “flow rate-energy flow rate” diagrams as important characteristics of the blood flow. The measurement system presented here can be used as an additional instrument in neurosurgery for assessment and monitoring of the operation procedure. Clinical data obtained with the system are used for construction of mathematical models and patient-specific simulations. The monitoring of the blood flow parameters during endovascular interventions was approved by the Ethics Committee at the Meshalkin Novosibirsk Research Institute of Circulation Pathology and included in certain surgical protocols for pre-, intra- and postoperative examinations.

    Full Text Available Aviation as a mode of transportation requires that the aircraft designed, developed, andoperated must be maintained under airworthy condition. The basic tenet of airworthiness is thatthe aircraft designed and developed are certified by the independent airworthiness regulatoryorganisations. This requires strict vigil during the development stages. With quantum jump inthe design and development activities, it has been extremely difficult for the regulatory bodiesto cope up with the demand of certification. Delegating this responsibility to a few approvedfirms prove very effective in maintaining the design control through approved agencies andpersonnel. Airworthiness approval of design firms taken up by the Centre for MilitaryAirworthiness & Certification, Bangalore, which is the airworthiness approval authority for militaryaircraft in India, is one such step. This paper discusses the scope and extent of such approvals.

  7. The dilemma of approving antidotes.

    Science.gov (United States)

    Steffen, Christian

    2007-04-20

    Clinical trials with antidotes are difficult to perform for a variety of practical, ethical, and financial reasons. As acute poisoning is a rare event, the commercial interest in basic and clinical research is low. Poisoned patients are usually not available for normal clinical trial procedures and, if they are, they cannot give informed consent. This situation results in a dilemma: antidotes are essential drugs. A resolution of the Council of Europe requests to guarantee the optimal availability of antidotes and the improvement of their use. As comprehensive data on the efficacy of antidotes are often missing, a marketing authorisation under exceptional circumstances according to Article 14(8) of Regulation (EC) No. 276/2004, will often be the only way to get an approval, as: (1) the indications for which the product in question is intended are encountered so rarely that the applicant cannot reasonably be expected to provide comprehensive evidence ("orphan drug"), (2) in the present state of scientific knowledge, comprehensive information cannot be provided, or (3) it would be contrary to generally accepted principles of medical ethics to collect such data. Typically, data on antidotes are obtained from a patchwork of studies with animals, human tissue and a few observations from human poisoning corroborated with data from clinical observations and biochemistry. Generalisations from chemical and mechanistic similarities between groups of poisons are usual, but often lack scientific evidence. Current standards of good clinical practice can rarely be observed. Therefore, public funding and other financial support are necessary incentives to initiate trials in this important area. PMID:17207900

  8. Oral Application of T4 Phage Induces Weak Antibody Production in the Gut and in the Blood

    Directory of Open Access Journals (Sweden)

    Joanna Majewska

    2015-08-01

    Full Text Available A specific humoral response to bacteriophages may follow phage application for medical purposes, and it may further determine the success or failure of the approach itself. We present a long-term study of antibody induction in mice by T4 phage applied per os: 100 days of phage treatment followed by 112 days without the phage, and subsequent second application of phage up to day 240. Serum and gut antibodies (IgM, IgG, secretory IgA were analyzed in relation to microbiological status of the animals. T4 phage applied orally induced anti-phage antibodies when the exposure was long enough (IgG day 36, IgA day 79; the effect was related to high dosage. Termination of phage treatment resulted in a decrease of IgA again to insignificant levels. Second administration of phage induces secretory IgA sooner than that induced by the first administrations. Increased IgA level antagonized gut transit of active phage. Phage resistant E. coli dominated gut flora very late, on day 92. Thus, the immunological response emerges as a major factor determining phage survival in the gut. Phage proteins Hoc and gp12 were identified as highly immunogenic. A low response to exemplary foreign antigens (from Ebola virus presented on Hoc was observed, which suggests that phage platforms can be used in oral vaccine design.

    1997-01-01

    NASA turbomachinery computer codes assisted in the design of the Cleveland Clinic Foundation's centrifugal bladed blood pump. The codes were originally developed for the aerospace industry, but are applicable to the blood pump because of a high degree of synergy with this application. Traditional turbomachinery design criteria were used in the design of the blood pump centrifugal impeller and volute casing. The fluid dynamic performance of the blood pump is meeting the engineering design goals of flow rate and pressure rise.

    2010-09-01

    Last year, we reported in vitro pump performance, low hemolytic characteristics, and initial in vivo evaluation of a disposable, magnetically levitated centrifugal blood pump, MedTech Dispo. As the first phase of the two-stage in vivo studies, in this study we have carried out a 2-week in vivo evaluation in calves. Male Holstein calves with body weight of 62.4–92.2 kg were used. Under general anesthesia, a left heart bypass with a MedTech Dispo pump was instituted between the left atrium and the descending aorta via left thoracotomy. Blood-contacting surface of the pump was coated with a 2-methacryloyloxyethyl phosphorylcholine polymer. Post-operatively, with activated clotting time controlled at 180–220 s using heparin and bypass flow rate maintained at 50 mL/kg/min, plasma-free hemoglobin (Hb), coagulation, and major organ functions were analyzed for evaluation of biocompatibility. The animals were electively sacrificed at the completion of the 2-week study to evaluate presence of thrombus inside the pump,together with an examination of major organs. To date, we have done 13 MedTech Dispo implantations, of which three went successfully for a 2-week duration. In these three cases, the pump produced a fairly constant flow of 50 mL/Kg/min. Neurological disorders and any symptoms of thromboembolism were not seen. Levels of plasma-free Hb were maintained very low. Major organ functions remained within normal ranges. Autopsy results revealed no thrombus formation inside the pump. In the last six cases, calves suffered from severe pneumonia and they were excluded from the analysis. The MedTech Dispo pump demonstrated sufficient pump performance and biocompatibility to meet requirements for 1-week circulatory support. The second phase (2-month in vivo study) is under way to prove the safety and efficacy of MedTech Dispo for 1-month applications.

  14. Quantitative spatially resolved measurement of tissue chromophore concentrations using photoacoustic spectroscopy: application to the measurement of blood oxygenation and haemoglobin concentration

    Energy Technology Data Exchange (ETDEWEB)

    A new approach based on pulsed photoacoustic spectroscopy for non-invasively quantifying tissue chromophore concentrations with high spatial resolution has been developed. The technique is applicable to the quantification of tissue chromophores such as oxyhaemoglobin (HbO{sub 2}) and deoxyhaemoglobin (HHb) for the measurement of physiological parameters such as blood oxygen saturation (SO{sub 2}) and total haemoglobin concentration. It can also be used to quantify the local accumulation of targeted contrast agents used in photoacoustic molecular imaging. The technique employs a model-based inversion scheme to recover the chromophore concentrations from photoacoustic measurements. This comprises a numerical forward model of the detected time-dependent photoacoustic signal that incorporates a multiwavelength diffusion-based finite element light propagation model to describe the light transport and a time-domain acoustic model to describe the generation, propagation and detection of the photoacoustic wave. The forward model is then inverted by iteratively fitting it to measurements of photoacoustic signals acquired at different wavelengths to recover the chromophore concentrations. To validate this approach, photoacoustic signals were generated in a tissue phantom using nanosecond laser pulses between 740 nm and 1040 nm. The tissue phantom comprised a suspension of intralipid, blood and a near-infrared dye in which three tubes were immersed. Blood at physiological haemoglobin concentrations and oxygen saturation levels ranging from 2% to 100% was circulated through the tubes. The signal amplitude from different temporal sections of the detected photoacoustic waveforms was plotted as a function of wavelength and the forward model fitted to these data to recover the concentrations of HbO{sub 2} and HHb, total haemoglobin concentration and SO{sub 2}. The performance was found to compare favourably to that of a laboratory CO-oximeter with measurement resolutions of {+-}3

  14. Testing (HIV). Quick test receives Singapore approval.

    Science.gov (United States)

    1996-04-22

    Hema-Strip HIV 1/2 is a rapid HIV antibody immunoassay developed by Saliva Diagnostic Systems, Inc. (SDS) which can be used by anyone who can read the product insert. The test kit is comprised of a small lancet for a finger stick, a cylindrical tube with a capillary tip and a SDS diagnostic strip inside, and a vial of buffer. Once blood is drawn by the lancet, the capillary tip is placed upon the blood droplet and the blood is automatically drawn into the tube. The tube is then inserted tip first into the vial of buffer. The buffer and blood migrate over the diagnostic strip inside, yielding stable results within 15 minutes. Studies have found Hema-Strip HIV 1/2 to have a sensitivity and specificity greater than 99.4%, as accurate as most conventional HIV tests which require the use of laboratory equipment and trained staff, and possibly hours to produce results. Moreover, the test kit requires neither refrigeration nor special storage. Hema-Strip HIV 1/2 has received a certificate of free sale from the Ministry of Health in Singapore and is now being submitted for regulatory approval in Brazil, China, Russia, India, Malaysia, Thailand, and the UK. SDS products in production include Sero-Strip HIV 1/2, a rapid serum-based HIV antibody test; Omni-SAL, a saliva collector which is the principal sample collection device used by British insurance companies for HIV testing with other confirmatory tests; Omni-Swab, a serrated swab which collects body fluids or cells; Saliva-Sampler, a saliva collection device used for general testing purposes; and Saliva Check, a test which checks the composition of saliva samples. SDS is in the final stages of developing Saliva-Strip HIV-1/2, a rapid saliva-based HIV antibody test. The company also intends to complete development in 1996 of a rapid blood-based antibody test for the Helicobacter pylori bacteria, a pathogen linked to 80% of peptic ulcers and gastric cancers.

Nuclear Regulatory Commission (NRC) has accepted and approved the use of digital control technology for safety-related applications within the nuclear power industry. This analysis reviews cases of existing digitally-based control systems that have been approved by the NRC. These cases can serve as precedence for using similar types of digitally-based control technologies within the Subsurface Repository. While it is anticipated that the Yucca Mountain Project (YMP) will not contain control systems as complex as those required for a nuclear power plant, the review of these existing NRC approved applications will provide the YMP with valuable insight into the NRCs review process and design expectations for safety-related digital control systems. According to the YMP Compliance Program Guidance, portions of various NUREGS, Regulatory Guidelines, and nuclear IEEE standards the nuclear power plant safety related concept would be applied to some of the designs on a case-by-case basis. This analysis will consider key design methods, capabilities, successes, and important limitations or problems of selected control systems that have been approved for use in the Nuclear Power industry. An additional purpose of this analysis is to provide background information in support of further development of design criteria for the YMP.

    The Texas Railroad Commission (RRC), working in partnership with the United States Department of Energy and the oil and gas industry it regulates, is implementing a strategy for improving efficiency in regulations and significantly reducing administrative operating costs through the Electronic Compliance and Approval Process (ECAP). The project will streamline regulatory compliance and reporting by providing the ability to electronically submit, process, and query oil and gas applications and reports through the Internet-based ECAP system. Implementation of an ECAP drilling permit pilot project began September 1999 after funding resources were secured--a $700,000 grant from the U.S. Department of Energy and an appropriation of $1.4 million from the Texas Legislature. The pilot project involves creating the ability to file, review, and approve a well's drilling permit application through a completely electronic process. The pilot project solution will ultimately provide the infrastructure, technology, and electronic modules to enable the filing of all compliance permits and performance reports through the internet from a desktop computer. The pilot project was conducted in three phases. The first phase, implemented May 2000, provided the infrastructure that allows the electronic filing and approval of simple drilling permit applications, associated fees, and attachments. The official ''roll-out'' of ECAP and the first electronically filed drilling permit application occurred on May 11, 2000 in Dallas in conjunction with an Internet Workshop sponsored by the Petroleum Technology Transfer Council. After the completion of Phase I, the ECAP team conducted an extensive review of progress to date and analyzed requirements and opportunities for future steps. The technical team identified core infrastructure modifications that would facilitate and better support future development and expansion of the ECAP system and work began on database structure

  7. Viral metagenomics and blood safety.

    2016-02-01

    The characterization of the human blood-associated viral community (also called blood virome) is essential for epidemiological surveillance and to anticipate new potential threats for blood transfusion safety. Currently, the risk of blood-borne agent transmission of well-known viruses (HBV, HCV, HIV and HTLV) can be considered as under control in high-resource countries. However, other viruses unknown or unsuspected may be transmitted to recipients by blood-derived products. This is particularly relevant considering that a significant proportion of transfused patients are immunocompromised and more frequently subjected to fatal outcomes. Several measures to prevent transfusion transmission of unknown viruses have been implemented including the exclusion of at-risk donors, leukocyte reduction of donor blood, and physicochemical treatment of the different blood components. However, up to now there is no universal method for pathogen inactivation, which would be applicable for all types of blood components and, equally effective for all viral families. In addition, among available inactivation procedures of viral genomes, some of them are recognized to be less effective on non-enveloped viruses, and inadequate to inactivate higher viral titers in plasma pools or derivatives. Given this, there is the need to implement new methodologies for the discovery of unknown viruses that may affect blood transfusion. Viral metagenomics combined with High Throughput Sequencing appears as a promising approach for the identification and global surveillance of new and/or unexpected viruses that could impair blood transfusion safety.

  15. Unilateral approval - Is it working?

    International Nuclear Information System (INIS)

    MDS Nordion, owned by Canadian based MDS Inc., designs, manufactures and uses transport packages for the distribution of radioactive materials used in the medical, research and sterilisation industries. Each of these packages must be proven to meet the International Atomic Energy Agency (IAEA) transport regulations. This paper will explore the unilateral approval concept as well as provide examples of its implementation. The IAEA transport regulations are recognised and implemented across the world. They include the unilateral approval concept of a single competent authority approval of the package design. Although the performance standards set by the IAEA regulations for Type B(U) packages have been accepted and implemented in national legislation, national authorities tend to require additional reviews of the safety analysis report. Case studies will be presented to demonstrate that the concept of unilateral approval is not applied consistently between all IAEA member states, and that this has impeded the efficient transport of radioactive material. The studies also show that these additional reviews have not resulted in changes to the design of a transport package. The lack of recognition of the IAEA unilateral approval for transport packages is a barrier to the effective transport of packages. These additional reviews require allocation of resources for both the company and the regulatory agency. As a responsible partner in a very unique industry, MDS Nordion encourages all IAEA member states to accept Type B(U) transport certificate from other jurisdictions without requiring additional review or endorsement. In this respect, the collaboration of the competent authorities is important to reduce this regulatory impediment and allowing the effective transport of radioactive material. (author)

  16. Reduction of low-density lipoprotein cholesterol, plasma viscosity, and whole blood viscosity by the application of pulsed corona discharges and filtration

    Science.gov (United States)

    Jung, Jin M.; Fridman, Alexander; Cho, Daniel J.; Cho, Young I.

    2013-03-01

    The present study investigated the feasibility of applying pulsed corona discharges to blood plasma to reduce the viscosity of blood plasma and whole blood. Blood plasma was separated from blood cells, treated with corona discharges, and filtered before it was re-mixed with blood cells. Plasma viscosity (PV), whole blood viscosity (WBV), and low-density lipoprotein (LDL)-c concentration were measured before and after the corona treatment and filtration. Both PV and WBV increased in the case of the corona treatment only, whereas both of them decreased in the case of the corona treatment plus filtration. In particular, the LDL-c decreased in the case of the corona treatment plus filtration by 31.5% from the baseline value. The effect of the corona treatment on the reduction of the WBV was significant at low shear rates, but not at high shear rates, suggesting that the precipitation of the molecules in blood plasma by the corona treatment and subsequent removal may suppress the aggregation of erythrocytes and improve rheological properties of blood.

    Public health response to large scale chemical emergencies presents logistical challenges for sample collection, transport, and analysis. Diagnostic methods used to identify and determine exposure to chemical warfare agents, toxins, and poisons traditionally involve blood collection by phlebotomists, cold transport of biomedical samples, and costly sample preparation techniques. Use of dried blood spots, which consist of dried blood on an FDA-approved substrate, can increase analyte stability, decrease infection hazard for those handling samples, greatly reduce the cost of shipping/storing samples by removing the need for refrigeration and cold chain transportation, and be self-prepared by potentially exposed individuals using a simple finger prick and blood spot compatible paper. Our laboratory has developed clinical assays to detect human exposures to nerve agents through the analysis of specific protein adducts and metabolites, for which a simple extraction from a dried blood spot is sufficient for removing matrix interferents and attaining sensitivities on par with traditional sampling methods. The use of dried blood spots can bridge the gap between the laboratory and the field allowing for large scale sample collection with minimal impact on hospital resources while maintaining sensitivity, specificity, traceability, and quality requirements for both clinical and forensic applications.

    In preparing to support the Army in 2025 and beyond, the Army Blood Program remains actively engaged with the research and advanced development of blood products and medical technology to improve blood safety and efficacy in conjunction with the US Army Medical Research and Materiel Command. National and International Blood Bank authorities have noted that the US Army research and development efforts in providing new blood products and improving blood safety operate on the cutting edge of technology and are transformational for the global blood industry. Over the past 14 years, the Army has transformed how blood support is provided and improved the survival rate of casualties. Almost every product or process developed by or for the military has found an application in treating civilian patients. Conflicts have many unwanted consequences; however, in times of conflict, one positive aspect is the identification of novel solutions to improve the safety and efficacy of the blood supply.

    A novel kind of red-blood-cell-like bovine serum albumin (BSA)/Zn3(PO4)2 hybrid particle is prepared at room temperature by a facile and rapid one-step method based on coordination between BSA and zinc ion. The morphology of the monodisperse hybrid particle shows oblate spheroidal type with a one sided single hole on the surface. The hybrid particle is constructed with BSA/Zn3(PO4)2 nanoplates of 35 nm thick. The average particle size of hybrid particle is 2.3 μm, and its BET specific surface area is 146.64 cm2/g. To clarify the evolution of BSA/Zn3(PO4)2 hybrid particle, SEM and elemental analysis as a function of particle growth time are investigated. The formation mechanism of BSA/Zn3(PO4)2 hybrid particle, which can be described as crystallization, coordination and self-assembly process, is illustrated in detail. The as-prepared BSA/Zn3(PO4)2 hybrid particle is used for adsorption of Cu2+. The hybrid particle displayed excellent adsorption properties on Cu2+. The adsorption efficiency of BSA/Zn3(PO4)2 hybrid particles at 5 min and 30 min are 86.33% and 98.9%, respectively. The maximum adsorption capacity is 6.85 mg/g. Thus, this kind of novel adsorbent shows potential application value in ultra-fast and highly efficient removal of Cu2+.

  1. Regulatory approval of pharmaceuticals without a randomised controlled study: analysis of EMA and FDA approvals 1999–2014

    Science.gov (United States)

    Hatswell, Anthony J; Baio, Gianluca; Berlin, Jesse A; Irs, Alar; Freemantle, Nick

    2016-01-01

    Introduction The efficacy of pharmaceuticals is most often demonstrated by randomised controlled trials (RCTs); however, in some cases, regulatory applications lack RCT evidence. Objective To investigate the number and type of these approvals over the past 15 years by the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA). Methods Drug approval data were downloaded from the EMA website and the ‘Drugs@FDA’ database for all decisions on pharmaceuticals published from 1 January 1999 to 8 May 2014. The details of eligible applications were extracted, including the therapeutic area, type of approval and review period. Results Over the period of the study, 76 unique indications were granted without RCT results (44 by the EMA and 60 by the FDA), demonstrating that a substantial number of treatments reach the market without undergoing an RCT. The majority was for haematological malignancies (34), with the next most common areas being oncology (15) and metabolic conditions (15). Of the applications made to both agencies with a comparable data package, the FDA granted more approvals (43/44 vs 35/44) and took less time to review products (8.7 vs 15.5 months). Products reached the market first in the USA in 30 of 34 cases (mean 13.1 months) due to companies making FDA submission before EMA submissions and faster FDA review time. Discussion Despite the frequency with which approvals are granted without RCT results, there is no systematic monitoring of such treatments to confirm their effectiveness or consistency regarding when this form of evidence is appropriate. We recommend a more open debate on the role of marketing authorisations granted without RCT results, and the development of guidelines on what constitutes an acceptable data package for regulators.

  12. Microfluidic Devices for Blood Fractionation

    Directory of Open Access Journals (Sweden)

    Chwee Teck Lim

    2011-07-01

    Full Text Available Blood, a complex biological fluid, comprises 45% cellular components suspended in protein rich plasma. These different hematologic components perform distinct functions in vivo and thus the ability to efficiently fractionate blood into its individual components has innumerable applications in both clinical diagnosis and biological research. Yet, processing blood is not trivial. In the past decade, a flurry of new microfluidic based technologies has emerged to address this compelling problem. Microfluidics is an attractive solution for this application leveraging its numerous advantages to process clinical blood samples. This paper reviews the various microfluidic approaches realized to successfully fractionate one or more blood components. Techniques to separate plasma from hematologic cellular components as well as isolating blood cells of interest including certain rare cells are discussed. Comparisons based on common separation metrics including efficiency (sensitivity, purity (selectivity, and throughput will be presented. Finally, we will provide insights into the challenges associated with blood-based separation systems towards realizing true point-of-care (POC devices and provide future perspectives.

    To obtain single-source short tandem repeat (STR) profiles in trace female/male blood mixture samples, we combined florescence in situ hybridization (FISH), laser microdissection, and low volume PCR (LV-PCR) to isolate male/female cells and improve sensitivity. The results showed that isolation of as few as 10 leukocytes was sufficient to yield full STR profiles in fresh female or male blood samples for 32 independent tests with a low additional alleles rate (3.91%) and drop-out alleles rate (5.01%). Moreover, this procedure was tested in two fresh blood mixture series at three ratios (1:5, 1:10, and 1:20), two mock female/male blood mixture casework samples, and one practical casework sample. Male and female STR profiles were successfully detected in all of these samples, showing that this procedure could be used in forensic casework in the future.

    Perfusion-weighted magnetic resonance (MR) imaging using contrast agents plays a key role in characterizing tumors of the brain. We have shown that double-echo perfusion-weighted MR imaging (DEPWI) is potentially useful in assessing brain tumors. Quantitative indices, such as tumor blood volume, are obtained using DEPWI, which allows correction of underestimation of tumor blood volume due to leakage of contrast agents from tumor vessels, in addition to simultaneous acquisition of tumor vessel...

  18. Possible FDA-approved drugs to treat Ebola virus infection.

    Science.gov (United States)

    Yuan, Shu

    2015-01-01

    There is currently no effective treatment for the Ebola virus (EBOV) thus far. Most drugs and vaccines developed to date have not yet been approved for human trials. Two FDA-approved c-AbI1 tyrosine kinase inhibitors Gleevec and Tasigna block the release of viral particles; however, their clinical dosages are much lower than the dosages required for effective EBOV suppression. An α-1,2-glucosidase inhibitor Miglustat has been shown to inhibit EBOV particle assembly and secretion. Additionally, the estrogen receptor modulators Clomiphene and Toremifene prevent membrane fusion of EBOV and 50-90% of treated mice survived after Clomiphene/Toremifene treatments. However, the uptake efficiency of Clomiphene by oral administration is very low. Thus, I propose a hypothetical treatment protocol to treat Ebola virus infection with a cumulative use of both Miglustat and Toremifene to inhibit the virus effectively and synergistically. EBOV infection induces massive apoptosis of peripheral lymphocytes. Also, cytolysis of endothelial cells triggers disseminated intravascular coagulation (DIC) and subsequent multiple organ failures. Therefore, blood transfusions and active treatments with FDA-approved drugs to treat DIC are also recommended. PMID:25984303

  20. Approval of radioactive consumer goods

    International Nuclear Information System (INIS)

    The 1980 Euratom Directive obliges the UK to draw up a system of prior authorization for the use of radioactive substances in a range of consumer products, and the Government intends to make regulations to fulfil the requirements of the Directive. These regulations will empower NRPB to approve such products prior to their supply to the public. In this brief article, the NRPB reviews the criteria against which to consider any proposed use of radioactive substances, considers radiological production standards for products and discusses the questions of the labelling of radioactive consumer goods.

    RNAi therapeutics provide an opportunity to correct faulty genes, and several RNAi have entered clinical evaluation. The existing quantification methods typically use radioactivity- or fluorescence-labeled RNAi, require large blood volumes, and/or have a limited dynamic detection range. We established a quantitative reverse transcriptase real-time polymerase chain reaction (RT-qPCR) assay to measure RNAi; the model analyte was survivin siRNA (siSurvivin). A second siRNA was used as the internal standard. The three major steps were (a) extraction of the two siRNAs from blood or water, (b) synthesis of their cDNA by poly-A extension, and (c) qPCR of cDNA. Standard curves were established. Utility of the assay was demonstrated in a pharmacokinetic study where all 12 samples for the blood concentration-time profile were obtained from a single mouse given an intravenous dose of 1 nmole siSurvivin (prepared as lipoplex with pegylated cationic liposomes). The RT-qPCR assay was sensitive (lower detection limit of 100 fM) and had a 5 × 107-fold dynamic range and low sample volume requirement (10 μL). The 16-point standard curves constructed using whole blood samples were linear (R (2) > 0.98). The intraday and interday variations for the slopes were ≤6%, although the variations for accuracy and precision at individual concentrations were substantially higher (58-145%). Standard curves prepared with water in place of blood showed similar results (water may be used when blood is not available. The current RT-qPCR assay enabled the measurement of nonlabeled siRNA in small volume of blood samples. PMID:26286676

    Introduction. Clotiapine is an atypical antipsychotic of the dibenzothiazepine class introduced in a few European countries since 1970, efficient in treatment-resistant schizophrenic patients. There is little published data on the therapeutic and toxic concentrations of this drug. Aims. The aim of the present study is the development and validation of a method that allows the detection and quantification of clotiapine in blood and urine specimens by gas chromatography-mass spectrometry (GC-MS). Methods. Validation was performed working on spiked postmortem blood and urine samples. Samples were extracted with liquid-liquid extraction (LLE) technique at pH 8.5 with n-hexane/dichloromethane (85/15 v/v) and analysis was followed by GC-MS. Methadone-d9 was used as internal standard. Results. The limit of detection (LOD) was 1.2 and 1.3 ng/mL for urine and blood, respectively, while the lower limit of quantification (LLOQ) was 3.9 and 4.3 ng/mL, respectively. Linearity, precision, selectivity, accuracy, and recovery were also determined. The method was applied to a postmortem case. The blood and urine clotiapine concentrations were 1.32 and 0.49 μg/mL, respectively. Conclusions. A reliable GC-MS method for the detection and quantification of clotiapine in blood and urine samples has been developed and fully validated and then applied to a postmortem case. PMID:26236337

    McEwen Mark P

    2007-08-01

    Full Text Available Abstract Background Trauma/retrieval patients are often in shock and hypothermic. Treatment of such patients usually involves restoring their blood volume with transfusion of blood (stored at 2°C – 6°C and/or crystalloids or colloids (stored at ambient temperature. Rapid infusion of these cold fluids can worsen or even induce hypothermia in these patients. Warming of intravenous fluids at accident sites has traditionally been difficult due to a lack of suitable portable fluid warmers that are not dependent on mains electrical or battery power. If latent heat, the heat released when a liquid solidifies (an inherently temperature limiting process can warm intravenous fluids, portable devices without a reliance on electrical energy could be used to reduce the incidence of hypothermia in trauma patients. Methods Rapid infusion of red cells into patients was timed to sample typical clinical flow rates. An approved dry heat blood warmer was compared with a prototype blood warmer using a supercooled liquid latent heat storage material, to warm red cells whilst monitoring inlet and outlet temperatures. To determine the effect of warming on red cell integrity compared to the normal storage lesion of blood, extracellular concentrations of potassium, lactate dehydrogenase and haemoglobin were measured in blood which had been warmed after storage at 2°C – 6°C for 1 to 42 days. Results A prototype latent heat fluid warmer consistently warmed red cells from approximately 4°C to approximately 35°C at typical clinical flow rates. Warming of stored blood with latent heat did not affect red cell integrity more than the approved dry heat blood warmer. Conclusion Using latent heat as an energy source can satisfactorily warm cold blood or other intravenous fluids to near body temperature, without any adverse affects.

    Research and development of new drugs requires both long time and high costs, whereas safety and tolerability profiles make the success rate of approval very low. Drug repurposing, applying known drugs and compounds to new indications, has been noted recently as a cost-effective and time-unconsuming way in developing new drugs, because they have already been proven safe in humans. In this review, we discuss drug repurposing of approved cardiovascular drugs, such as aspirin, beta-blockers, angiotensin converting enzyme inhibitors, angiotensin II receptor blockers, cardiac glycosides and statins. Regarding anti-tumor activities of these agents, a number of experimental studies have demonstrated promising pleiotropic properties, whereas all clinical trials have not shown expected results. In pathological conditions other than cancer, repurposing of cardiovascular drugs is also expanding. Numerous experimental studies have reported possibilities of drug repurposing in this field and some of them have been tried for new indications ('bench to bedside'), while unexpected results of clinical studies have given hints for drug repurposing and some unknown mechanisms of action have been demonstrated by experimental studies ('bedside to bench'). The future perspective of experimental and clinical studies using cardiovascular drugs are also discussed.

  18. Optimization of a high-throughput whole blood expression profiling methodology and its application to assess the pharmacodynamics of interferon (IFN beta-1a or polyethylene glycol-conjugated IFN beta-1a in healthy clinical trial subjects

    Full Text Available Abstract Background Clinical trials offer a unique opportunity to study human disease and response to therapy in a highly controlled setting. The application of high-throughput expression profiling to peripheral blood from clinical trial subjects could facilitate the identification of transcripts that function as prognostic or diagnostic markers of disease or treatment. The paramount issue for these methods is the ability to produce robust, reproducible, and timely mRNA expression profiles from peripheral blood. Single-stranded complementary DNA (sscDNA targets derived from whole blood exhibit improved detection of transcripts and reduced variance as compared to their complementary RNA counterparts and therefore provide a better option for interrogation of peripheral blood on oligonucleotide arrays. High-throughput microarray technologies such as the high-throughput plate array platform offer several advantages compared with slide- or cartridge-based arrays; however, manufacturer’s protocols do not support the use of sscDNA targets. Results We have developed a highly reproducible, high-through put, whole blood expression profiling methodology based on sscDNA and used it to analyze human brain reference RNA and universal human reference RNA samples to identify experimental conditions that most highly correlated with a gold standard quantitative polymerase chain reaction reference dataset. We then utilized the optimized method to analyze whole blood samples from healthy clinical trial subjects treated with different versions of interferon (IFN beta-1a. Analysis of whole blood samples before and after treatment with intramuscular [IM] IFN beta-1a or polyethylene glycol-conjugated IFN (PEG-IFN beta-1a under optimized experimental conditions demonstrated that PEG-IFN beta-1a induced a more sustained and prolonged pharmacodynamic response than unmodified IM IFN beta-1a. These results provide validation of the utility of this new methodology and

  17. Money for Blood and Markets for Blood.

    Science.gov (United States)

    Derpmann, Simon; Quante, Michael

    2015-12-01

    Ontario's Bill 178 proposing a Voluntary Blood Donations Act declares the offer or acceptance of payment for the donation of blood a legal offence and makes it subject to penalty. The bill reinvigorates a fundamental debate about the ethical problems associated with the payment of money for blood. Scarcity of blood donors is a recurring problem in most health systems, and monetary remuneration of the willingness to donate blood is regularly discussed--and sometimes practiced--as a means to overcome scarcity in blood. However, making blood an object of economic exchange has long aroused ethical concerns that often refer to the specific meaning of blood. From the perspective of a modern understanding of money as a metric of economic value, the exchange of money for blood--shed or given--is seen as ethically troubling, because it appears to imply a commensurability of the value of human life and economic wealth. In this paper, we begin with a general taxonomy of the types of arguments that speak in favour or against compensating donors for giving blood. We then describe the context in which the discussion about payment for blood arises, and of the specific aims and concerns that are brought forward in this context. This is used to reconstruct the normative background that supports the rejection of payment for blood as it is envisaged in Bill 178 and the aims of the proposal. We then argue that while a payment indeed changes the nature of a blood donation in an ethically considerable way, we do not believe that decisive arguments against the monetary remuneration of blood donations can be substantiated, at least not independently of assuming specific societal circumstances. Thus it may be possible to establish a stable and safe blood supply through just gratification while at the same time taking strong provisions against social disconnection, injustice, exploitation or heteronomy.

  18. Optical properties of blood in motion

    Lindberg, Lars-Goran; Oberg, P. Ake

    1993-02-01

    An in vitro model is developed for application in studies of the optical and physical characteristics of flowing blood in rigid and flexible tubes (artificial vessels). The results indicate that both transmission and reflection of light are dependent on blood volume changes and orientation as well as the deformability of the red blood cells. Light transmission and reflection in human blood shows a parabolic behavior at hematocrit levels greater than 40%, when plotted against blood flow. At both low and high flow rates, the light transmission increases when compared to an intermediate flow where the transmission shows a minimum. The optical wavelength used also affects the light transmission and reflection in moving blood. The results of studies of blood in flow-through models are important for the understanding of the optical mechanisms behind the signal generation in photometrical measurement techniques.

    An efficient and robust method to measure vitamin D (25-hydroxy vitamin D3 (25(OH)D3) and 25-hydroxy vitamin D2 in dried blood spots (DBS) has been developed and applied in the pan-European multi-centre, internet-based, personalised nutrition intervention study Food4Me. The method includes calibration with blood containing endogenous 25(OH)D3, spotted as DBS and corrected for haematocrit content. The methodology was validated following international standards. The performance characteristics did not reach those of the current gold standard liquid chromatography-MS/MS in plasma for all parameters, but were found to be very suitable for status-level determination under field conditions. DBS sample quality was very high, and 3778 measurements of 25(OH)D3 were obtained from 1465 participants. The study centre and the season within the study centre were very good predictors of 25(OH)D3 levels (Pnutritional study.

    2010-01-01

    The paper deals with the theoretical investigation of a fundamental problem of biomagnetic fluid flow through a porous medium subject to a magnetic field by using the principles of biomagnetic fluid dynamics(BFD).The study pertains to a situation where magnetization of the fluid varies with temperature.The fluid is considered to be non-Newtonian,whose flow is governed by the equation of a second-grade viscoelastic fluid.The walls of the channel are assumed to be stretchable,where the surface velocity is proportional to the longitudinal distance from the origin of coordinates.The problem is first reduced to solving a system of coupled nonlinear differential equations involving seven parameters.Considering blood as a biomagnetic fluid and using the present analysis,an attempt is made to compute some parameters of the blood flow by developing a suitable numerical method and by devising an appropriate finite difference scheme.The computational results are presented in graphical form,and thereby some theoretical predictions are made with respect to the hemodynamical flow of the blood in a hyperthermal state under the action of a magnetic field.The results clearly indicate that the presence of a magnetic dipole bears the potential so as to affect the characteristics of the blood flow in arteries to a significant extent during the therapeutic procedure of electromagnetic hyperthermia.The study will attract the attention of clinicians,to whom the results would be useful in the treatment of cancer patients by the method of electromagnetic hyperthermia.

    In this paper, the novel poly(lactic-co-glycolic acid)-F127 nanospheres (PLGA-F127 NSs) were synthesized and used to establish an amperometric glucose biosensor that can be applied in whole blood directly. This property of glucose biosensor was based on the antibiofouling property of PLGA-F127 NSs. More details of preparing PLGA-F127 NSs and immobilizing glucose oxidase (GOx) on (PLGA-F127)/glass carbon electrode (GCE) were presented. Then, the electrochemical behaviors of the biosensor in whole blood were studied. The cyclic voltammetric results indicated that GOx immobilized on PLGA-F127 NSs exhibited direct electron transfer reaction, which led to stable amperometric biosensing for glucose with a detection limit of 5.57 x 10(-6) M (S/N = 3). The glucose biosensor did not respond to ascorbic acid (AA) and uric.acid (UA) at their concentration normally encountered in blood. The development of materials science will bring significant input to high-performance biosensors relevant to diagnostics and therapy of interest for human health. PMID:26328311

    The peripheral blood film (PBF) is a laboratory work-up that involves cytology of peripheral blood cells smeared on a slide. As basic as it is, PBF is invaluable in the characterization of various clinical diseases. This article highlights the basic science and art behind the PBF. It expounds its laboratory applications, clinical indications and interpretations in the light of various clinical diseases. Despite advances in haematology automation and application of molecular techniques, the PBF has remained a very important diagnostic test to the haematologist. A good quality smear, thorough examination and proper interpretation in line with patient's clinical state should be ensured by the haemato-pathologist. Clinicians should be abreast with its clinical utility and proper application of the reports in the management of patients. PMID:25960697

    The use of blood products as essential medicines and the recognition of the high risk associated with blood transfusions require governments to take regulatory action with a focus on quality and safety. In this scenario, regulatory agencies play an essential role in socially advancing the guarantee that blood components will be produced according to current operating rules. Thus, in the effort to manage sanitary risks involved in the processing and use of blood, the Brazilian regulatory model, based on the construction of a national blood policy overseen by the State, has undergone conceptual improvement and review of the tools employed to achieve its goals. With the inclusion of good manufacturing practices as part of the Brazilian norms, as recommended by the World Health Organization, the country has moved forward in its view of blood facilities as manufacturing centers producing blood-derived biologics for therapeutic applications. It has also strengthened the need to develop safety mechanisms for blood donors and recipients. The development of a State-coordinated national blood policy and the institution of a national surveillance system with legitimate power of inspection are essential elements used in Brazil to guarantee the amount, quality, safety, and timeliness of blood supply to the population. The present article aims to discuss the present context of the blood regulatory model in Brazil so as to identify the challenges for improvement of this model. PMID:26758225

    Three column osteotomies (3CO) of the lumbar spine are powerful corrective procedures used in the treatment of kyphoscoliosis. Their efficacy comes at the cost of high reported complication rates, notably significant estimated blood loss (EBL). Previously reported techniques to reduce EBL have had modest efficacy. Here we describe a potential technique to decrease EBL during pedicle subtraction osteotomy (PSO) of the lumbar spine by means of pre-operative vertebral body embolization - a technique traditionally used to reduce blood loss prior to spinal column tumor resection. We present a 62-year-old man with iatrogenic kyphoscoliosis who underwent staged deformity correction. Stage 1 involved thoracolumbar instrumentation followed by transarterial embolization of the L4 vertebral body through bilateral segmental arteries. A combination of polyvinyl alcohol particles and Gelfoam (Pfizer, New York, NY, USA) were used. Following embolization there was decreased angiographic blood flow to the small vessels of the L4 vertebral body, while the segmental arteries remained patent. Stage 2 consisted of an L4 PSO and fusion. The EBL during the PSO procedure was 1L, which compared favorably to that during previous PSO at this institution as well as to quantities reported in previous literature. There have been no short term (5 month follow-up) complications attributable to the vertebral body embolization or surgical procedure. Although further investigation into this technique is required to better characterize its safety and efficacy in reducing EBL during 3CO, we believe this patient illustrates the potential utility of pre-operative vertebral embolization in the setting of non-oncologic deformity correction surgery.

    We explore monitoring the death process of individual red blood cells (RBC) quantitatively by using thermal lens (TL) response. TL response is a noninvasive excitation/probe technique that reflects photothermal parameters (e.g., absorption, thermal diffusivity, size, etc.). Since these parameters of cells change significantly during certain biological processes, real-time TL response was performed to monitor RBC death process when incubated with ionomycin. Theoretical model developed was applied to curve-fit the TL response for extracting thermal diffusivity and size of cells. Thermal diffusivity of dying RBC is found increased by 1.7 times in comparison with healthy cell.

  17. A viewpoint on the approval context of strategic environmental assessments

    International Nuclear Information System (INIS)

    A reflection on the last report from the Commission to the Council, the European Parliament, the European Economic and Social Committee and the Committee of the Regions on the application and effectiveness of the Directive on Strategic Environmental Assessment (SEA) is provided. It covers the inadequacies of the approval/permitting context of SEA, which appears to be increasingly applied by a significant number of Member States in recent years. A viewpoint is provided on the main deficiencies of such praxis. As a practical defence of the planning context of SEA, the authors propose that the EC should consider a clear recommendation to Member States to cease performing SEA in the approval/permitting context until proper amendments to the SEA Directive are made and implemented. - Highlights: ► Administrative and permitting context of SEA, has ousted the primary environmental impact assessment goal. ► The approval context moves from the environmental protection to the area of political power and economy. ► SEA and EIA are misused. ► Environmental evaluations should be used for improving the projects/plans/programmes and not for permitting them.

    Testing donations for pathogens and deferring selected blood donors have reduced the risk of transmission of known pathogens by transfusion to extremely low levels in most developed countries. Protecting the blood supply from emerging infectious threats remains a serious concern in the transfusion medicine community. Transfusion services can employ indirect measures such as surveillance, hemovigilance, and donor questioning (defense), protein-, or nucleic acid based direct testing (detection), or pathogen inactivation of blood products (destruction) as strategies to mitigate the risk of transmission-transmitted infection. In the North American context, emerging threats currently include dengue, chikungunya, and hepatitis E viruses, and Babesia protozoan parasites. The 2003 SARS and 2014 Ebola outbreaks illustrate the potential of epidemics unlikely to be transmitted by blood transfusion but disruptive to blood systems. Donor-free blood products such as ex vivo generated red blood cells offer a theoretical way to avoid transmission-transmitted infection risk, although biological, engineering, and manufacturing challenges must be overcome before this approach becomes practical. Similarly, next generation sequencing of all nucleic acid in a blood sample is currently possible but impractical for generalized screening. Pathogen inactivation systems are in use in different jurisdictions around the world, and are starting to gain regulatory approval in North America. Cost concerns make it likely that pathogen inactivation will be contemplated by blood operators through the lens of health economics and risk-based decision making, rather than in zero-risk paradigms previously embraced for transfusable products. Defense of the blood supply from infectious disease risk will continue to require innovative combinations of surveillance, detection, and pathogen avoidance or inactivation. PMID:26962008

    Dragon's blood is a commonly used Chinese herbal medicine shown to have protective effects in simulated microgravity in rats and mice. The current study aimed to develop an ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS) method for simultaneous determination of four phenolic components from the herb: loureirin A, loureirin C, 7,4'-dihydroxyflavone and pterostilbene in rats, and use the method for comparative study on the pharmacokinetics (PK) and excretion of these components in rats after oral dosage of dragon's blood under simulated microgravity environments. The results showed the developed UHPLC-MS method was sensitive and rapid. The comparative pharmacokinetic study in rats showed loureirin A, loureirin C and 7,4-dihydroxyflavone had decreased Cmax and AUC and increased Vd and CL in simulated microgravity environment; but pterostilbene had the opposite changes. The four phenolic components also showed increased or decreased excretions in simulated microgravity rats. These results indicate the chemical structure and physicochemical property, as well as physiological conditions may have an impact on the absorption and excretion of phenolic components in simulated microgravity environment. It also implies that different drug may behave differently in the same spaceflight condition leading to an increase or a reduction in pharmacodynamic outcomes. PMID:26799977

    MedTech Dispo, a disposable maglev centrifugal blood pump with two degrees of freedom magnetic suspension and radial magnetic coupling rotation, has been developed for 1-month extracorporeal circulatory support. As the first stage of a two-stage in vivo evaluation, 2-week evaluation of a prototype MedTech Dispo was conducted. In in vitro study, the pump could produce 5 L/min against 800 mm Hg and the normalized index of hemolysis was 0.0054 +/- 0.0008 g/100 L. In in vivo study, the pump, with its blood-contacting surface coated with biocompatible 2-methacryloyloxyethyl phosphorylcholine polymer, was implanted in seven calves in left heart bypass. Pump performance was stable with a mean flow of 4.49 +/- 0.38 L/min at a mean speed of 2072.1 +/- 64.5 rpm. The maglev control revealed its stability in rotor position during normal activity by the calves. During 2 weeks of operation in two calves which survived the intended study period, no thrombus formation was seen inside the pump and levels of plasma free hemoglobin were maintained below 4 mg/dL. Although further experiments are required, the pump demonstrated the potential for sufficient and reliable performance and biocompatibility in meeting the requirements for cardiopulmonary bypass and 1-week circulatory support.

    A cDNA clone has been derived from the plasma of a chimpanzee with chronic non-A, non-B viral hepatits (NANBH). The authors have assayed for antibodies reacting with the encoded antigen in sera from posttransfusion hepatitis patients (643 samples from 23 patients) and their corresponding donors collected during the past 10 years in Japan. The antibody was detected in 15 out of 17 (88.2%) posttransfusion NANBH (PT-NANBH) patients whose sera over time displayed multiple alanine aminotransferase (ALT) peaks. In general, the antibody was detected after several peaks of serum ALT elevations and, once detected, it persisted for years. Of the 15 well-defined cases of PT-NANBH that showed multiple ALT peaks and hepatitis C virus seroconversions, 11 (73.3%) were shown to be transfused with at least one unit of blood positive for the antibody. The retrospective analysis showed that all tested donor blood found to be positive for the antibody had been transfused to recipients who afterwards developed NANBH. These data strongly suggest that the cloned cDNA originated from an etiological agent of NANBH termed the hepatitis C virus. Furthermore, the present study demonstrates that had the screening been done with the anti-hepatitis C virus assay, 11 out of 17 (64.7%) cases of chronic PT-NANBH and 1 out of 6 (16.6%) acute PT-NANBH would have been prevented.

    The postmortem redistribution (PMR) phenomenon complicates interpretation in forensic toxicology. Human data on time-dependent PMR are rare and only exist for blood so far. A new method for investigation of time-dependent PMR in blood as well as in alternative body fluids and tissues was developed and evaluated using automated biopsy sampling. At admission of the bodies, introducer needles were placed in liver, lung, kidney, muscle, spleen, adipose tissue, heart, femoral vein, and lumbar spine using a robotic arm guided by a computed tomography scanner (CT). Needle placement accuracy was analyzed and found to be acceptable for the study purpose. Tissue biopsies and small volume body fluid samples were collected in triplicate through the introducer needles. At autopsy (around 24 h after admission), samples from the same body regions were collected. After mastering of the technical challenges, two authentic cases were analyzed as a proof of concept. Drug concentrations of venlafaxine, O-desmethylvenlafaxine, bromazepam, flupentixol, paroxetine, and lorazepam were determined by LC-MS/MS, and the percentage concentration changes between the two time points were calculated. Concentration changes were observed with both increases and decreases depending on analyte and matrix. While venlafaxine, flupentixol, paroxetine, and lorazepam generally showed changes above 30% and more, O-desmethylvenlafaxine and bromazepam did not undergo extensive PMR. The presented study shows that CT-controlled biopsy collection provides a valuable tool for systematic time-dependent PMR investigation, demanding only minimal sample amount and causing minimal damage to the body.

  18. Laboratory testing of hemolytic properties of materials that come in contact with blood: Comparative application testing method’s two variants according to the standard ASTM F756 in accordance with ISO 10993-4

    Directory of Open Access Journals (Sweden)

    Pavlović Katarina B.

    2010-01-01

    Full Text Available The presence of hemolytic material in contact with blood may produce increased levels of blood cell lysis and increased levels of plasma hemoglobin. This may induce toxic effects or other effects which may stress the kidneys or other organs. In this paper two variants of in vitro method and obtained results’ comparison were presented for testing of hemolytic properties of six raw materials (Polipropylene Moplen EP 540 P, Policarbonate colorless 164 R-112, Policarbonate brown 164 R-51918, Polietylene NG 3026 K, Polietylene NG - Purell GB 7250, Polietylene VG - Hiplex 5502 for medical device manufacturing and one raw material (Polietylen NG granulate used for infusion solutions’s plastic bottles manufacturing. One of method’s variants relies on raw material direct contact with swine blood and the other on extract of the material contact with swine blood. Both method’s variants imply reading of the absorbance of the supernatant after tubes were incubated and centrifuged. According to values obtained and using the standard curve free hemoglobin concentration is determined and based on this percentage hemolysis of raw material. Positive and negative controls were used in both variants where water for injection (WFI was used as positive control in which partial or complete hemolysis of erythrocytes occurs due to osmotic shock and phosphate buffer saline was used as negative control with no hemolytic property. In this paper comparison of results obtained by both method’s variants for testing of seven raw materials was presented, while these conclusions can not be used neither for all materials, nor for all applications without preliminary testing using both variants and then choosing more sensitive and more reliable one. It was shown and stated in the paper as well that incubation time being 3, 15 or 24 h, had no impact on the variant’s with direct contact sensitivity. This comparative approach was used for drawing conclusions in terms of

    Full Text Available A simple, sensitive and selective cloud point extraction procedure is described for the preconcentration and atomic absorption spectrometric determination of Zn2+ and Cd2+ ions in water and biological samples, after complexation with 3,3',3",3'"-tetraindolyl (terephthaloyl dimethane (TTDM in basic medium, using Triton X-114 as nonionic surfactant. Detection limits of 3.0 and 2.0 µg L-1 and quantification limits 10.0 and 7.0 µg L-1were obtained for Zn2+ and Cd2+ ions, respectively. Relative standard deviation was 2.9 and 3.3, and enrichment factors 23.9 and 25.6, for Zn2+ and Cd2+ ions, respectively. The method enabled determination of low levels of Zn2+ and Cd2+ ions in urine, blood serum and water samples.

  20. Renal Arteriovenous Fistula with Rapid Blood Flow Successfully Treated by Transcatheter Arterial Embolization: Application of Interlocking Detachable Coil as Coil Anchor

    International Nuclear Information System (INIS)

    A 70-year-old woman presented to our outpatient clinic with a large idiopathic renal arteriovenous fistula (AVF). Transcatheter arterial embolization (TAE) using interlocking detachable coils (IDC) as an anchor was planned. However, because of markedly rapid blood flow and excessive coil flexibility, detaching an IDC carried a high risk of migration. Therefore, we first coiled multiple loops of a microcatheter and then loaded it with an IDC. In this way, the coil was well fitted to the arterial wall and could be detached by withdrawing the microcatheter during balloon occlusion ('pre-framing technique'). Complete occlusion of the afferent artery was achieved by additional coiling and absolute ethanol. This technique contributed to a safe embolization of a high-flow AVF, avoiding migration of the IDC
