    The accurate measurement of a stress level is one of the most important issues in a stress diagnosis and its measurement could be of great value in clinical medicine. Stress has a potent effect on the spirit and physical condition of an individual. There are various methods available for its measurement. Some of the commonly used techniques for the diagnosis of a stress level include analysis of the body fluids, questionnaire assessments, psychophysiological evaluations and by determining heart rate variability (HRV) of subjects. However, the existing diagnostic methods have several defects like, a low sensitivity, inaccuracy and long of operation time. In this report, we present a diagnostic technology to detect a stress level which is the origin of various diseases. This method can be of great help in providing an early diagnosis through a biosensor and might play a vital role in preventing diseases like hypochondria and hypertension. Majority of the human population is exposed to stress in one way or another and hence developing a convenient stress diagnosis kit will be of great use to all. This stress diagnostic kit and detection technology dose not involve simple a mechanical measurement or questionnaires, but is based on developing a detection kit with a high sensitivity, which will mean an easy use for common man. Individuals can undergo regular check ups and can personally diagnose their present situation of health by determining their stress levels, thus enabling them to diagnose the early onset of several stress disorders. This might help them take precautionary measures and thereby lead to a healthy life.

    Full Text Available The recent outbreak of Ebola Virus Disease (EVD in West Africa has ravaged many lives. Effective containment of this outbreak relies on prompt and effective coordination and communication across various interventions; early detection and response being critical to successful control. The use of information and communications technology (ICT in active surveillance has proved to be effective but its use in Ebola outbreak response has been limited. Due to the need for timeliness in reporting and communication for early discovery of new EVD cases and promptness in response; it became imperative to empower the response team members with technologies and solutions which would enable smooth and rapid data flow. The Open Data Kit and Form Hub technology were used in combination with the Dashboard technology and ArcGIS mapping for follow up of contacts, identification of cases, case investigation and management and also for strategic planning during the response. A remarkable improvement was recorded in the reporting of daily follow-up of contacts after the deployment of the integrated real time technology. The turnaround time between identification of symptomatic contacts and evacuation to the isolation facility and also for receipt of laboratory results was reduced and informed decisions could be taken by all concerned. Accountability in contact tracing was ensured by the use of a GPS enabled device. The use of innovative technologies in the response of the EVD outbreak in Nigeria contributed significantly to the prompt control of the outbreak and containment of the disease by providing a valuable platform for early warning and guiding early actions.

    2014-01-01

    Acid-base bifunctional mesoporous catalysts Al-KIT-6-NH 2 containing different aluminum content have been synthesized through post synthetic grafting method. The materials were characterized by X-ray diffraction (XRD), scanning electron micrographs (SEM), transmission electron micrographs (TEM), Fourier-transform infrared spectroscopy (FTIR), IR spectra of pyridine adsorption, NH 3 -TPD and TG analysis. The characterization results indicated that the pore structure of KIT-6 was well kept after the addition of aluminum and grafting of aminopropyl groups. The acid amount of Al-KIT-6 increased with enhancing aluminum content. Catalytic results showed that weak acid and weak base favor the Knoevenagel reaction, while catalysts with strong acid and weak base exhibited worse catalytic behavior. - Graphical abstract: The postulated steps of mechanism for the acid-base catalyzed process are as follows: (1) the aldehyde gets activated by the surface acidic sites which allow the amine undergoes nucleophilic to attack the carbonyl carbon of benzaldehyde. (2) Water is released in the formation of imine intermediate. (3) The ethyl cyanoacetate reacts with the intermediate. (4) The benzylidene ethyl cyanoacetate is formed and the amine is regenerated. - Highlights: • KIT-6 and Al-KIT-6-NH 2 with different Si/Al ratios has been successfully prepared. • 79.4% Yield was obtained over 46-Al-KIT-6-NH 2 within 20 min in Knoevenagel reaction. • Low Al-content Al-KIT-6-NH 2 shows better catalytic stability than high Al-content catalysts. • There is acid-base synergistic effect in Knoevenagel reaction

    Hospitalized palliative patients need to keep in touch with their loved ones. Regular social contact may be especially difficult for individuals on palliative care in-patient units due to the isolating nature of hospital settings. Technology can help mitigate isolation by facilitating social connection. This study aimed to explore the acceptability of introducing internet-based communication and information technologies for patients on a palliative care in-patient unit. In the first phase of the Keep in Touch (KIT) project, a diverse group of key informants were consulted regarding their perspectives on web-based communication on in-patient palliative care units. Participants included palliative patients, family members, direct care providers, communication and information technology experts, and institutional administrators. Data was collected through focus groups, interviews and drop-in consultations, and was analyzed for themes, consensus, and major differences across participant groups. Hospitalized palliative patients and their family members described the challenges of keeping in touch with family and friends. Participants identified numerous examples of ways that communication and information technologies could benefit patients' quality of life and care. Patients and family members saw few drawbacks associated with the use of such technology. While generally supportive, direct care providers were concerned that patient requests for assistance in using the technology would place increased demands on their time. Administrators and IT experts recognized issues such as privacy and costs related to offering these technologies throughout an organization and in the larger health care system. This study affirmed the acceptability of offering internet-based communication and information technologies on palliative care in-patient units. It provides the foundation for trialing these technologies on a palliative in-patient unit. Further study is needed to confirm the

    2012-01-01

    Full Text Available The Karlsruhe Institute of Technology (KIT is one of the largest research and higher education organisations in the world focusing on engineering and natural sciences. At present KIT, under the chairmanship of its executive board, is installing an extensive current research information system (CRIS covering all institutes and facilities of the organisation. The assumption underlying the project is that a consistent overview of research performance has become fundamental for the international competitiveness of research institutions and is increasingly important for strategic decisions at the executive level. Ultimately, it also leads to better data and control in rankings at higher education assessments. The new research information system systematically maps all of KIT’s processes and instruments to obtain, connect, present and utilise the research metadata of active researchers. This reduces the documentation workload for researchers, for the executive level and central units such as the library, and at the same time allows for and facilitates an overall view and the aggregation and visualisation of research metadata. Our vision is to build a federally structured network of systems that gathers information on KIT’s publications, research competence, research projects, patents and technological offers by retrieving data from external and internal sources as well as directly from the researchers. The network facilitates linking and aggregating of data and provides unique identifiers for individual researchers and organizational units. With its consistent data model the research information system also fosters the organisational development of KIT, which was formed in 2009 by the merger of a university and a national research centre. The researchers and their activities are at the core of the research information system. The system substantially reduces their administrative burden in documenting project information and publications. Automatic

    Confinement to an in-patient hospital ward impairs patients' sense of social support and connectedness. Providing the means, through communication technology, for patients to maintain contact with friends and family can potentially improve well-being at the end of life by minimizing social isolation and facilitating social connection. This study aimed to explore the feasibility of introducing internet-based communication and information technologies for in-patients and their families and to describe their experience in using this technology. A cross-sectional survey design was used to describe patient and family member experiences in using internet-based communication technology and health care provider views of using such technology in palliative care. Participants included 13 palliative in-patients, 38 family members, and 14 health care providers. An iPad or a laptop computer with password-protected internet access was loaned to each patient and family member for about two weeks or they used their own electronic devices for the duration of the patient's stay. Quantitative and qualitative data were collected from patients, families, and health care providers to discern how patients and families used the technology, its ease of use and its impact. Descriptive statistics and paired sample t-tests were used to analyze quantitative data; qualitative data were analyzed using constant comparative techniques. Palliative patients and family members used the technology to keep in touch with family and friends, entertain themselves, look up information, or accomplish tasks. Most participants found the technology easy to use and reported that it helped them feel better overall, connected to others and calm. The availability of competent, respectful, and caring technical support personnel was highly valued by patients and families. Health care providers identified that computer technology helped patients and families keep others informed about the patient's condition, enabled

    One of the major needs of the law enforcement field is a product that quickly, accurately, and inexpensively identifies whether a person has recently fired a gun--even if the suspect has attempted to wash the traces of gunpowder off. The Field Test Kit for Gunshot Residue Identification based on Sandia National Laboratories technology works with a wide variety of handguns and other weaponry using gunpowder. There are several organic chemicals in small arms propellants such as nitrocellulose, nitroglycerine, dinitrotoluene, and nitrites left behind after the firing of a gun that result from the incomplete combustion of the gunpowder. Sandia has developed a colorimetric shooter identification kit for in situ detection of gunshot residue (GSR) from a suspect. The test kit is the first of its kind and is small, inexpensive, and easily transported by individual law enforcement personnel requiring minimal training for effective use. It will provide immediate information identifying gunshot residue.

    A kit for prescreening protein concentration for crystallization includes a multiplicity of vials, a multiplicity of pre-selected reagents, and a multiplicity of sample plates. The reagents and a corresponding multiplicity of samples of the protein in solutions of varying concentrations are placed on sample plates. The sample plates containing the reagents and samples are incubated. After incubation the sample plates are examined to determine which of the sample concentrations are too low and which the sample concentrations are too high. The sample concentrations that are optimal for protein crystallization are selected and used.

    Infant asphyxia is a condition due to insufficient oxygen intake suffered by newborn babies. A 4 to 9 million occurrences of infant asphyxia are reported each year by WHO. Early diagnosis of asphyxia is important to avoid complications such as damage to the brain, organ and tissue that could lead to fatality. This is possible with the automation of screening of infant asphyxia. Here, a non-invasive Asphyxia Screening Kit is developed. It is a Graphical User Interface that automatically detects asphyxia in infants from early birth to 6 months from their cries and displays the outcome of analysis. It is built with Matlab GUI underlied with signal processing algorithms, capable of achieving a classification accuracy of 96.03%. Successful implementation of ASK will assist to screen infant asphyxia for reference to clinicians for early diagnosis. In addition, ASK also provides an interface to enter patient information and images to be integrated with existing Hospital Information Management System.

    1989-01-01

    Clinco-radiological seminars are an effective method of teaching medical students. However, in busy departments it is often difficult to provide enough radiologists for small group instruction. This can be facilitated by the use of prepared teaching kits. Each kit contains a set of duplicated films and a syllabus which gives a short clinical history for each patient and a series of questions to be used to direct the discussion. Each diagnostic problem is chosen to demonstrate core material. We have been using these teaching kits for organ system teaching in the preclerkship year. Teaching kits offer several advantages. They make it easier to recruit seminar leaders through efficient use of their time. The use of duplicated films and a syllabus ensures that all students cover the same material. The syllabus can be used to generate examination questions for reinforcement of important concepts. The kits are also available to students to review alone and can be readily updated as required

    2014-01-01

    The Integrated Medical Model (IMM) is a probabilistic model that estimates medical event occurrences and mission outcomes for different mission profiles. IMM simulation outcomes describing the impact of medical events on the mission may be used to optimize the allocation of resources in medical kits. Efficient allocation of medical resources, subject to certain mass and volume constraints, is crucial to ensuring the best outcomes of in-flight medical events. We implement a new approach to this medical kit optimization problem. METHODS We frame medical kit optimization as a modified knapsack problem and implement an algorithm utilizing a dynamic programming technique. Using this algorithm, optimized medical kits were generated for 3 different mission scenarios with the goal of minimizing the probability of evacuation and maximizing the Crew Health Index (CHI) for each mission subject to mass and volume constraints. Simulation outcomes using these kits were also compared to outcomes using kits optimized..RESULTS The optimized medical kits generated by the algorithm described here resulted in predicted mission outcomes more closely approached the unlimited-resource scenario for Crew Health Index (CHI) than the implementation in under all optimization priorities. Furthermore, the approach described here improves upon in reducing evacuation when the optimization priority is minimizing the probability of evacuation. CONCLUSIONS This algorithm provides an efficient, effective means to objectively allocate medical resources for spaceflight missions using the Integrated Medical Model.

    2017-11-30

    Data collection in Sub-Saharan Africa has traditionally been paper-based. However, the popularization of Android mobile devices and data capture software has brought paperless data management within reach. We used Open Data Kit (ODK) technology on Android mobile devices during a household survey in the Niger Delta region of Nigeria. The aim of this study was to describe the pros and cons of deploying ODK for data management. A descriptive cross-sectional household survey was carried out by 6 data collectors between April and May 2016. Data were obtained from 1706 persons in 601 households across 6 communities in 3 states in the Niger Delta. The use of Android mobile devices and ODK technology involved form building, testing, collection, aggregation, and download for data analysis. The median duration for data collection per household and per individual was 25.7 and 9.3 min, respectively. Data entries per device ranged from 33 (33/1706, 1.93%) to 482 (482/1706, 28.25%) individuals between 9 (9/601, 1.5%) and 122 (122/601, 20.3%) households. The most entries (470) were made by data collector 5. Only 2 respondents had data entry errors (2/1706, 0.12%). However, 73 (73/601, 12.1%) households had inaccurate date and time entries for when data collection started and ended. The cost of deploying ODK was estimated at US $206.7 in comparison with the estimated cost of US $466.7 for paper-based data management. We found the use of mobile data capture technology to be efficient and cost-effective. As Internet services improve in Africa, we advocate their use as effective tools for health information management. ©Omosivie Maduka, Godwin Akpan, Sylvester Maleghemi.

    The Virtual Physiological Human (VPH) is a major European e-Science initiative intended to support the development of patient-specific computer models and their application in personalized and predictive healthcare. The VPH Network of Excellence (VPH-NoE) project is tasked with facilitating interaction between the various VPH projects and addressing issues of common concern. A key deliverable is the 'VPH ToolKit'--a collection of tools, methodologies and services to support and enable VPH research, integrating and extending existing work across Europe towards greater interoperability and sustainability. Owing to the diverse nature of the field, a single monolithic 'toolkit' is incapable of addressing the needs of the VPH. Rather, the VPH ToolKit should be considered more as a 'toolbox' of relevant technologies, interacting around a common set of standards. The latter apply to the information used by tools, including any data and the VPH models themselves, and also to the naming and categorizing of entities and concepts involved. Furthermore, the technologies and methodologies available need to be widely disseminated, and relevant tools and services easily found by researchers. The VPH-NoE has thus created an online resource for the VPH community to meet this need. It consists of a database of tools, methods and services for VPH research, with a Web front-end. This has facilities for searching the database, for adding or updating entries, and for providing user feedback on entries. Anyone is welcome to contribute.

    All reagents for tumor markers assays are imported from various manufacturers mainly CIS bio international. The average cost of these reagents is ranged from 80-150 bath/test (2-4 dollars test). The screening test for cancers could not be done especially in other regions of Thailand whose budgets and resources are so limited. If the reagents are made locally, many laboratories can perform the tests and use as primary diagnosis, screening or monitor the course of the disease following treatment. In addition, these reagents could help clinicians and give complementary information on the tumor status to improve quality of life in Thailand. Research objectives include: 1. Development of IRMA reagent kits suitable for diagnosing staging and monitoring prostrate and breast cancer. 2. Transfer of technology and reagent kits to relevant laboratories in Thailand. 3. Routine distribution of the reagents kits to the end users

    In the context of the renovation of controls and data acquisition electronics for accelerators the BE-CO-HT section at CERN has designed a kit based on carriers and mezzanines following the VITA FPGAMezzanine Card (FMC) standard. Carriers exist in VME64x and PCIe form factors, with a PXIe carrier underway. Mezzanines include an Analog to Digital Converter, a Time to Digital Converter, a fine delay generator and a Digital Input/Output. All of the designs are licensed under the CERN Open Hardware Licence and commercialised by companies. This paper discusses the benefits of this carrier mezzanine strategy and of the Open Hardware based commercial paradigm. It also explains the design of each layer of the FMC kit, from the hardware to the gateware and the Linux device driver. In addition, several tools to help designers developing gateware for mezzanines and new concepts such as the Self-Describing Bus (SDB) and the fmcbus are presented. Lastly, some of the plans for the future of the FMC kit and Open Hardware Re...

    Full Text Available Gliomas are the most common and devastating primary brain tumours. Despite therapeutic advances, the majority of gliomas do not respond either to chemo or radiotherapy. KIT, a class III receptor tyrosine kinase (RTK, is frequently involved in tumourigenic processes. Currently, KIT constitutes an attractive therapeutic target. In the present study we assessed the frequency of KIT overexpression in gliomas and investigated the genetic mechanisms underlying KIT overexpression. KIT (CD117 immunohistochemistry was performed in a series of 179 gliomas of various grades. KIT activating gene mutations (exons 9, 11, 13 and 17 and gene amplification analysis, as defined by chromogenic in situ hybridization (CISH and quantitative real-time PCR (qRT-PCR were performed in CD117 positive cases. Tumour cell immunopositivity was detected in 15.6% (28/179 of cases, namely in 25% (1/4 of pilocytic astrocytomas, 25% (5/20 of diffuse astrocytomas, 20% (1/5 of anaplastic astrocytomas, 19.5% (15/77 of glioblastomas and one third (3/9 of anaplastic oligoastrocytomas. Only 5.7% (2/35 of anaplastic oligodendrogliomas showed CD117 immunoreactivity. No association was found between tumour CD117 overexpression and patient survival. In addition, we also observed CD117 overexpression in endothelial cells, which varied from 0–22.2% of cases, being more frequent in high-grade lesions. No KIT activating mutations were identified. Interestingly, CISH and/or qRT-PCR analysis revealed the presence of KIT gene amplification in 6 glioblastomas and 2 anaplastic oligoastrocytomas, corresponding to 33% (8/24 of CD117 positive cases. In conclusion, our results demonstrate that KIT gene amplification rather than gene mutation is a common genetic mechanism underlying KIT expression in subset of malignant gliomas. Further studies are warranted to determine whether glioma patients exhibiting KIT overexpression and KIT gene amplification may benefit from therapy with anti-KIT RTK

  7. Personal radiotoxicological (first aid) kit

    International Nuclear Information System (INIS)

    Gachalyi, Andras; Gyulai, Gabor

    2014-01-01

    In recent years, with the spread of nuclear industrial activities, and the widespread use of radioactive materials and products the possibility of radionuclide contamination of humans and animals has significantly increased. During nuclear tests or reactor accidents, a large amount of radioactive materials may enter the environment which can contaminate the living environment (air, water, vegetation, soil), for a long period. This contamination may enter living organisms by inhalation, intake and ingestion, causing severe biological damage. As an example the Chernobyl reactor accident can be mentioned, where there was no possibility for the decorporation of isotopes, as there were no products available such as the 'RADISTOP'. To achieve appropriate decorporating (and decontaminating) treatment which is effective, it is highly recommendable to use a personal Radiotoxicological First Aid Kit (PRK) within the shortest possible time after internal contamination. This unit provides effective treatment to decorporate the most common incorporated fission products. (author)

    Nuclear Medicine Unit at Black Lion Hospital is the only Nuclear Medicine service giving center in the country. We have been importing Radiopharmaceutical-kits for 10 subsequent years costly, with frequent irregularities, only limited Numbers of kits mainly for Liver, Brain, Thyroid and Kidney imagings. Most of the Nuclear Medicine (NM) diagnostic procedures were not undertaken at our unit, because of unavailability of vital Radiopharmaceutical-kits (Rp-kits) in the country since they were not manufactured in the country. In order to solve this long stranding problem of the country persistent efforts were made. The success in Rp-kits manufacturing indigenously has the advantage of disseminating the NM Technology with in the country also. With the continuous efforts made 7 Aqueous-Rp-kits were manufactured successfully in our unit viza-viz: 1) 99m Tc-s-colloid-for Liver imaging. 2) 99m Tc-DTPA-for Brain + Renal imaging. 3) 99m Tc-MDP-for Bone imaging, 4) 99m Tc-Tin (11) pyrophosphate for in-vivo R,B,C, labelling: (For the study of Blood-Pool and Myocardial Infarction), 5) 99m Tc-Tin(11) Gluconate for Brain + Kidney Static imaging. 6) 99m Tc-Tin(11) Phytate for Liver imaging. 7) 99m Tc-TBI for Myocardial perfusion study. Their physico-chemical behaving patterns were studied and the chemical and biological quality control procedures were conducted upon the indigenously produced kits at the National Drug Quality Control center and they were found to be sterile, apyrogenic and non-toxic. The efficiency of the kits was tested in many patients in our unit and found to be effective and reliable. Aqueous kits produced were observed to be as effective and reliable as their lyophilized counterparts with respect to their physico-chemical properties and biospecificity (organ specificity) but possessing short shelf lives unlike lyophilized kits.

    1992-05-01

    This publication details preparation under Good Manufacturing Practices (GMP) of thirteen widely used 99 Tc m radiopharmaceuticals and their quality assurance practices. The objective of this document is to present to those who intend to launch a kit preparation programme a set of preparation procedures and other relevant information gathered during kit production over a period of more than a decade, to serve as a good starting point. The manuals and monographs included in the document are based on the experience gained in two major centres. The publication of this material is intended to give a typical example, and not the only possible procedure for preparing the kits. Following the essentials of these kit preparation procedures, it is always possible to make alterations to the composition of the kits. The kits described here concern widely used 99 Tc m radiopharmaceuticals which do not require a Single Photon Emission Computed Tomography (SPECT) camera. These examples of the ''first generation'' of kits are not very intricate to prepare. Although it is advisable to have only one agent for a given intended use, a few agents for each purpose, e.g. EHDP and MDP for bone imagining, have been included in the document so that the reader can have some flexibility in selecting a particular kit. 24 refs, 2 figs

In humans, its expression and mutations have been identified in malignant melanomas and therapies using molecular-targeted agents have been promising in these tumours. As human malignant melanoma, canine malignant melanoma is a fatal disease with metastases and the poor response has been observed with all standard protocols. In our study, KIT expression and exon 11 mutations in dogs with histologically confirmed malignant oral melanomas were evaluated. Although 20 of 39 cases were positive for KIT protein, there was no significant difference between KIT expression and overall survival. Moreover, polymerase chain reaction amplification and sequencing of KIT exon 11 in 17 samples did not detect any mutations and proved disappointing. For several reasons, however, KIT expression and mutations of various exons including exon 11 should be investigated in more cases. © 2011 Blackwell Publishing Ltd.

    This system paper presents the Topology ToolKit (TTK), a software platform designed for the topological analysis of scalar data in scientific visualization. While topological data analysis has gained in popularity over the last two decades, it has not yet been widely adopted as a standard data analysis tool for end users or developers. TTK aims at addressing this problem by providing a unified, generic, efficient, and robust implementation of key algorithms for the topological analysis of scalar data, including: critical points, integral lines, persistence diagrams, persistence curves, merge trees, contour trees, Morse-Smale complexes, fiber surfaces, continuous scatterplots, Jacobi sets, Reeb spaces, and more. TTK is easily accessible to end users due to a tight integration with ParaView. It is also easily accessible to developers through a variety of bindings (Python, VTK/C++) for fast prototyping or through direct, dependency-free, C++, to ease integration into pre-existing complex systems. While developing TTK, we faced several algorithmic and software engineering challenges, which we document in this paper. In particular, we present an algorithm for the construction of a discrete gradient that complies to the critical points extracted in the piecewise-linear setting. This algorithm guarantees a combinatorial consistency across the topological abstractions supported by TTK, and importantly, a unified implementation of topological data simplification for multi-scale exploration and analysis. We also present a cached triangulation data structure, that supports time efficient and generic traversals, which self-adjusts its memory usage on demand for input simplicial meshes and which implicitly emulates a triangulation for regular grids with no memory overhead. Finally, we describe an original software architecture, which guarantees memory efficient and direct accesses to TTK features, while still allowing for researchers powerful and easy bindings and extensions

    DNA left at a crime scene was often limited in amount and far from pristine. To maximize the chance of recovering as much information as possible from such compromised samples, an appropriate extraction method using the available technologies needs to be devised. In this study, we used human blood, buffy coat and a total of 76 simulated touch DNA samples to test the effectiveness of the following five common DNA extraction methods, namely, Chelex® 100, QIAamp® DNA Blood Mini Kit, QIAamp® DNA Investigator Kit, QIAsymphony® DNA Investigator® Kit and DNA IQ™ system, in the recovery of such DNA. We demonstrated that the QIAamp® and QIAsymphony® DNA Investigator® Kits, and the DNA IQ™ system, exhibited a better effectiveness in DNA recovery amongst these methods and yielded extracts with higher success rate in subsequent DNA profiling. These extracts also generated profiles with better intra-colour signal balance. The findings in this work allowed us to propose an extraction approach as follows: 1) casework samples shall be extracted with the QIAamp®/QIAsymphony® DNA Investigator® Kits or the DNA IQ™ system, viz., QIAsymphony® DNA Investigator® Kit and DNA IQ™, due to their higher throughput, are for the touched DNA evidence from the volume crime, while QIAamp® DNA Investigator Kit is preferable for challenging bloodstain samples; and 2) control samples, such as buccal swab, with known identity can be extracted with the Chelex, due to their cheaper cost per sample.

    Society becomes increasingly dependent on photonics technologies; however there is an alarming lack of technological awareness among secondary school students. They associate photonics with experiments and components in the class room that seem to bear little relevance to their daily life. The Rocard Report [5] highlights the need for fostering students' scientific skills and technological awareness and identifies inquiry based learning (IBL) as a means to achieve this. Students need to actively do science rather than be silent spectators. The `Photonics Explorer' kit was developed as an EU funded project to equip teachers, free-of-charge, with educational material designed to excite, engage and educate European secondary school students using guided inquiry based learning techniques. Students put together their own experiments using up-to-date versatile components, critically interpret results and relate the conclusions to relevant applications in their daily life. They work hands-on with the material, thus developing and honing their scientific and analytical skills that are otherwise latent in a typical class room situation. A qualitative and quantitative study of the impact of the kit in the classroom was undertaken with 50 kits tested in 7 EU countries with over 1500 students in the local language. This paper reports on the results of the EU wide field tests that show the positive impact of the kit in raising the self-efficacy, scientific skills and interest in science among students and the effectiveness of the kit in implementing IBL strategies in classrooms across EU.

    The refrigerated food/medical sample storage compartment as a kit to the space shuttle orbiter is examined. To maintain the -10 F in the freezer kit, an active refrigeration unit is required, and an air cooled Stirling Cycle refrigerator was selected. The freezer kit contains two subsystems, the refrigeration unit, and the storage volume. The freezer must provide two basic capabilities in one unit. One requirement is to store 215 lbs of food which is consumed in a 30-day period by 7 people. The other requirement is to store 128.3 lbs of medical samples consisting of both urine and feces. The unit can be mounted on the lower deck of the shuttle cabin, and will occupy four standard payload module compartments on the forward bulkhead. The freezer contains four storage compartments.

    2004-10-01

    The results achieved in the nuclear energy field illustrate the exemplary nature of the cooperation between France and China. Over 20 years, China has developed the nuclear technology for generating electricity, using the expertise and knowledge of the AREVA Group. AREVA has been present in China since 1986 and now employs 3,500 staff there. The group supplied the nuclear islands for 4 reactors at Daya Bay and Ling Ao as well as technology and equipment for 4 more reactors at the Qinshan II and Tianwan plants. AREVA has developed an ambitious program for transferring technology to the Chinese industry and developing local skills. The group's objective is to remain China's partner of choice in terms of its nuclear program. During an official visit to France in June 2004, China's Vice Premier Zeng Peiyan said he was in favor of 'overall and long-lasting cooperation between China and France in the field of nuclear energy'. AREVA took the opportunity to sign two letters of intent for cooperation over technology from its next generation of nuclear reactors. Electricity consumption forecasts report a need for 900 GW through 2020 and the country's objective is to increase nuclear-generated electricity from 1% to 4% of its total output (36 GW: the equivalent of around twenty 1,500 MWe reactors). An official decision to build 4 new reactors was announced in July 2004 and a further decision concerning another 4 reactors is expected in the near future. Various construction sites are being considered, mainly along the country's eastern coast. An official decision to build four duplicate reactors was announced n July 2004. In addition to these four duplicate reactors to be built on existing sites, China has decided to build four 3. generation reactors at Yangjiang and Sanmen. An international call for tender was launched on September 28, 2004. AREVA will reply to the tender by offering its EPR model. AREVA also aims to expand its Chinese operations into exploring and extracting

    1998-01-01

    99m Tc-isonitriles have been shown to be a very promising substitute for Thallium-201 ( 201 TI) for myocardial perfusion imaging. In this study, the lyophilized kit of Methoxyisobutylisonitrile (MIBI) was prepared and labeled with 99m Tc. Several factors affecting the labeling yield such as the kit's stannous content, boiling time during labeling, and the volume of 99m Tc used during reconstitution were also investigated. The radiochemical purity (RCP) determination of the labeled product was analyzed by HPLC, solvent-extraction, TLC and ITLC-SG chromatographic methods in various systems. Animal biodistribution study performed in rats indicated the 99m Tc-MIBI accumulation in the myocardial is up to 3 hours with little or no redistribution. Toxicity studies performed indicate no clinical signs of abnormality in mice at injected dose equivalent in amount of 100 times the human dose in proportion to body weight. Stability studies of the labeled complex performed at room temperature showed no change in radiochemical purity (> 95%) 6 hours post-preparation. Compatibility and comparative studies were done using both MINT and commercially available MIBI kits and 99m Tc generator eluates. From the results obtained the MINT produced MIBI kits were found to be comparable in quality to that of commercials. (author)

  14. Inter-laboratory assessment of a prototype multiplex kit for determination of recent HIV-1 infection.

    Directory of Open Access Journals (Sweden)

    Kelly A Curtis

    Full Text Available BACKGROUND: Accurate and reliable laboratory-based assays are needed for estimating HIV-1 incidence from cross-sectional samples. We recently described the development of a customized, HIV-1-specific Bio-Plex assay that allows for the measurement of HIV-specific antibody levels and avidity to multiple analytes for improved HIV-1 incidence estimates. METHODS: To assess intra- and inter-laboratory assay performance, prototype multiplex kits were developed and evaluated by three distinct laboratories. Longitudinal seroconversion specimens were tested in parallel by each laboratory and kit performance was compared to that of an in-house assay. Additionally, the ability of the kit to distinguish recent from long-term HIV-1 infection, as compared to the in-house assay, was determined by comparing the reactivity of known recent (infected 12 months drug naïve specimens. RESULTS: Although the range of reactivity for each analyte varied between the prototype kit and in-house assay, a measurable distinction in reactivity between recent and long-term specimens was observed with both assays in all three laboratories. Additionally, kit performance was consistent between all three laboratories. The intra-assay coefficient of variation (CV, between sample replicates for all laboratories, ranged from 0.5% to 6.1%. The inter-laboratory CVs ranged from 8.5% to 21.3% for gp160-avidity index (a and gp120-normalized mean fluorescent intensity (MFI value (n, respectively. CONCLUSION: We demonstrate the feasibility of producing a multiplex kit for measuring HIV antibody levels and avidity, with the potential for improved incidence estimates based on multi-analyte algorithms. The availability of a commercial kit will facilitate the transfer of technology among diverse laboratories for widespread assay use.

    Full Text Available Instructional laboratories are common in engineering programs. Instructional laboratories should evolve with technology and support the changes in higher education, like the increased popularity of online courses. In this study, an affordable and portable laboratory kit was designed to replace the expensive on-campus equipment for two control systems courses. The complete kit costs under $135 and weighs under 0.68 kilograms. It is comprised of off-the-shelf components (e.g., Raspberry Pi, DC motor and 3D printed parts. The kit has two different configurations. The first (base configuration is a DC motor system with a position and speed sensor. The second configuration adds a Furuta inverted pendulum attachment with another position sensor. These configurations replicate most of the student learning outcomes for the two control systems courses for which they were designed.

  20. Training Educators to Teach the Sun and Space Weather Using a Kit of Tools

    Keesee, A. M.; Ensign, T.

    2014-12-01

    NASA provides a wealth of data from Heliospheric missions to the public, but educators face several challenges to using such data in the classroom. These include the knowledge of what is available and how to use it, a full understanding of the science concepts the data demonstrate, ability to obtain and maintain products to access data, and access to technology (such as computer labs) for anything other than testing. To surmount these challenges, the Educator Resource Center at the NASA Independent Validation and Verification (IV&V) Center in Fairmont, WV has developed an operational model that focuses on housing, maintaining, and lending out kits of necessary equipment along with training educators in the science concepts and use of kit materials. Following this model, we have developed a Sun and Space Weather kit and an educator professional development course that we have presented several times. The kit includes a classroom set of iPads utilized to access data from NASA missions and other sources as well as create video reports for project based outcomes, a set of telescopes for safe solar viewing, and materials to explore magnetic fields and the electromagnetic spectrum. We will present an overview of the training course, the kit materials, and lessons learned.

    2017-01-01

    Full Text Available The article considers the project of educational and research software and hardware kit designed for use in case-based educational project activities based on the theme of energetically autonomous robots. An important feature of the complex is its interdisciplinarity since robotics combines many fields of science and technology — mechanical design, electronics, programming, elements of artificial intelligence, energy science and others. Students can receive basic knowledge in these areas as well as gain practical skills in solving real problems that require a convergent approach. The kit serves as an experimental basis that allows to study intricacies of robot control and its hardware and software design while making structural changes, including using different power units: solar, fuel, thermoelectric and others. Power units (converters and the various sources of renewable energy may be considered both from the theoretical point of view, i.e. from the principles of their functioning and from the practical aspect — studying their practical application in real systems. Another important aspect of the system is the development of software architecture for a robot and for a team of robots as well as studying the interactions between them. In addition to performing the target task, ancillary tasks such as maintaining the battery level, communication with other team members in a multi-agent system, should be considered in the control algorithm of the robot, which allows to study the distribution of priorities between these objectives, as shown in the example of multicriteria optimization. The prototype of the kit and its usage according to the described approach have been partially validated by conducting computational experiments with algorithms based on different search methods (random search, closest source and multi-criteria optimization methods, multi-agent paradigm and adaptive control which show a variety of possible approaches and

  10. Performance of multiplex commercial kits to quantify cytokine and chemokine responses in culture supernatants from Plasmodium falciparum stimulations.

    Directory of Open Access Journals (Sweden)

    Gemma Moncunill

    Full Text Available Cytokines and chemokines are relevant biomarkers of pathology and immunity to infectious diseases such as malaria. Several commercially available kits based on quantitative suspension array technologies allow the profiling of multiple cytokines and chemokines in small volumes of sample. However, kits are being continuously improved and information on their performance is lacking.Different cytokine/chemokine kits, two flow cytometry-based (eBioscience® FlowCytomix™ and BD™ Cytometric Bead Array Human Enhanced Sensitivity and four Luminex®-based (Invitrogen™ Human Cytokine 25-Plex Panel, Invitrogen™ Human Cytokine Magnetic 30-Plex Panel, Bio-Rad® Bio-Plex Pro™ Human Cytokine Plex Assay and Millipore™ MILLIPLEX® MAP Plex Kit were compared. Samples tested were supernatants of peripheral blood mononuclear cells of malaria-exposed children stimulated with Plasmodium falciparum parasite lysates. Number of responses in range that could be detected was determined and reproducibility of duplicates was evaluated by the Bland-Altman test. Luminex® kits performed better than flow cytometry kits in number of responses in range and reproducibility. Luminex® kits were more reproducible when magnetic beads were used. However, within each methodology overall performance depended on the analyte tested in each kit. Within the Luminex® kits, the Invitrogen™ with polystyrene beads had the poorer performance, whereas Invitrogen™ with magnetic beads had the higher percentage of cytokines/chemokines with both readings in range (40%, followed by Bio-Rad® with magnetic beads (35%. Regarding reproducibility, the Millipore™ kit had the highest percentage (60% of cytokines/chemokines with acceptable limits of agreement (<30%, followed by the Invitrogen™ with magnetic beads (40% that had tighter limits of agreement.Currently available kits for cytokine and chemokine quantification differ in reproducibility and concentration range of accurate

    Rationale: Biological significance of c-Kit as a cardiac stem cell marker and role(s) of c-Kit+ cells in myocardial development or response to pathologic injury remain unresolved due to varied and discrepant findings. Alternative experimental models are required to contextualize and reconcile discordant published observations of cardiac c-Kit myocardial biology and provide meaningful insights regarding clinical relevance of c-Kit signaling for translational cell therapy. Objective: Demonstration of c-Kit myocardial biology through combined studies of both human and murine cardiac cells. Advancing understanding of c-Kit myocardial biology through creation and characterization of a novel, inducible transgenic c-Kit reporter mouse model that overcomes limitations inherent to knock-in reporter models, providing perspective to reconcile disparate viewpoints on c-Kit biology in the myocardium. Methods and Results: In vitro studies confirm a critical role for c-Kit signaling in both cardiomyocytes and cardiac stem cells. Activation of c-Kit receptor promotes cell survival and proliferation in stem cells and cardiomyocytes of either human or murine origin. For creation of the mouse model, the cloned mouse c-Kit promoter drives Histone2B-EGFP (H2BEGFP) expression in a doxycycline inducible transgenic reporter line. The combination of c-Kit transgenesis coupled to H2BEGFP readout provides sensitive, specific, inducible, and persistent tracking of c-Kit promoter activation. Tagging efficiency for EGFP+/c-Kit+ cells is similar between our transgenic versus a c-Kit knock-in mouse line, but frequency of c-Kit+ cells in cardiac tissue from the knock-in model is 55% lower than our transgenic line. The c-Kit transgenic reporter model reveals intimate association of c-Kit expression with adult myocardial biology. Both cardiac stem cells and a subpopulation of cardiomyocytes express c-Kit in uninjured adult heart, upregulating c-Kit expression in response to pathologic stress

    Most inaccuracies in the analysis of gases and electrolytes in arterial blood samples are due to preanalytic factors, among which is the type of equipment used for blood collection. Our objective was to compare arterial blood gas sample kits used under clinical conditions and to evaluate the impact of delay in estimation on variability in results. In 2 types of study we compared 5 kits (Radiometer's Pico 70, Becton Dickinson's Preset, SIMS Portex's Pro-Vent, SIMS-Concord's Pulsator, and Marquest's Quick ABG). In the first study kitsyringe assignment was randomized for collecting arterial blood samples from 160 consecutive patients to evaluate practical aspects of using them and the presence of bubbles in the samples taken. The second study evaluated the effects of delays of 30 and 60 minutes in estimation and of the type of heparin used in 54 blood samples. The kits which produced the fewest bubbles, gave samples with the greatest stability, and had the least impact on ion concentration were Radiometer's Pico 70 and SIMS-Portex's Pro-vent.

    Literature studies shows that lean manufacturing goes way back with the original founder Eli Whitney in year 1799. The main purpose of lean manufacturing is to identify and eliminate waste in production. The application of lean manufacturing can be carried out in any industrial processes with regards to the understanding of lean principles, theories and practices. Kitting is one of the important aspects in a successful production. The continuous supply of materials from store to production has to be systematic and able to achieve lean standard for it to be successful. The objective of this paper is to review the implementation of lean manufacturing in kitting assembly. Previous papers show that, the implementation of lean manufacturing in kitting assembly may be beneficial to the organization such as reduce in space occupancy, part shortages, lead time and manpower. Based on previous research, some industries may tend to change between kitting and line stocking which are due to lack of understanding when implementing kitting and causes longer lead time and materials overflow in store. With a proper understanding on what to kit, where to kit, how to kit, why to kit and who kits the material with a standardised process flow may ensure the success of kitting.

    The Healthy Heart Kit (HHK) is a risk management and patient education kit for the prevention of cardiovascular disease (CVD) and the promotion of CV health. There are currently no published data examining predictors of HHK use by physicians. The main objective of this study was to examine the association between physicians' characteristics (socio-demographic, cognitive, and behavioural) and the use of the HHK. All registered family physicians in Alberta (n=3068) were invited to participate in the "Healthy Heart Kit" Study. Consenting physicians (n=153) received the Kit and were requested to use it for two months. At the end of this period, a questionnaire collected data on the frequency of Kit use by physicians, as well as socio-demographic, cognitive, and behavioural variables pertaining to the physicians. The questionnaire was returned by 115 physicians (follow-up rate = 75%). On a scale ranging from 0 to 100, the mean score of Kit use was 61 [SD=26]. A multiple linear regression showed that "agreement with the Kit" and the degree of "confidence in using the Kit" was strongly associated with Kit use, explaining 46% of the variability for Kit use. Time since graduation was inversely associated with Kit use, and a trend was observed for smaller practices to be associated with lower use. Given these findings, future research and practice should explore innovative strategies to gain initial agreement among physicians to employ such clinical tools. Participation of older physicians and solo-practitioners in this process should be emphasized.

    In search of novel antipigmentation agents, a set of 3,840 compounds with natural-like synthetic or natural origin were screened against Kit (stem cell factor receptor). Emodin from the seed of Cassia tora and baicalin from Scutellariae radix showed potent inhibitory effects (IC(50) = 4.9 and 9.0 microM, respectively) on the phosphorylation of Kit. Emodin also blocked other receptor tyrosine kinase activities, such as epithelial growth factor receptor (EGFR), vascular endothelial growth factor receptor 2 (VEGFR-2), fibroblast growth factor receptor 1 (FGFR-1), platelet-derived growth factor receptor b (PDGFR-b). In contrast to emodin, aloe-emodin did not inhibit Kit activity at all. Emodin also blocked the cellular kinase activities of Kit and its down-stream p44/42 mitogen activated protein kinase (MAPK) in MO7e cells and human primary melanocytes. Emodin strongly suppressed the melanin synthesis triggered by stem cell factor (SCF) treatment. Also, emodin showed almost no toxicity up to 10 microM on cultured melanocytes as reported previously by other researchers. The results indicate that emodin is a good candidate for the development of antipigmentation agents since it can radically block the differentiation and proliferation of pigment cells by reducing Kit signaling.

    The Society of Physics Students is dedicated to performing outreach events to get the general public excited about physics. The SPS National Office established the Science Outreach Catalyst Kit program in 2001 to aid SPS chapters at colleges all around the world in their efforts to bring physics education to students of all ages. Each year SPS produces twenty-five SOCKs in conjunction with the National Institute of Standards and Technology to give to SPS chapters on a first come, first serve basis. I spent my time at the SPS offices this summer helping to develop the 2015 SOCK. We designed activities that help students from elementary to high school explore basic acoustics with everyday materials like cups, straws, string, balloons, and rubber bands. In this presentation I will discuss why we chose to include the activities we did and the process of making this year's SOCK a reality.

    Full Text Available The aim of this work was to prepare a kit of 99mTc-ceftizoxime (99mTc-CFT, with stability and biological activity preserved, able to identify a septic focus (E. coli in the experimental infection model in rats. The preparation of the CFT kit involved the use of lyophilized solutions containing the antibiotic ceftizoxime and the sodium dithionite reducing agent (6.0 mg/mL. After lyophilization, the kit was reconstituted with 1.0 mL of sodium 99mTc-pertechnetate solution (Na99mTcO4- with an activity of 370 MBq. The solution was boiled for 10 min and filtered through a cellulose ester filter. The labeling efficiency was on the order of 92%, remaining stable for six hours and the kit remained stable for two months. The biological activity of the 99mTc-CFT was evaluated by diffusion in agar impregnated with E.coli and S. aureus. Seven Wistar rats, weighing from 200 to 250 g, were used for the development of the septic focus. After 24 hours from the induction of the infectious site (E.coli, the animals were anesthetized and 0.1 mL of 99mTc-CFT (37 MBq was injected into the tail veins of the animals. The images were obtained with a gamma camera one, two and six hours after injection and the regions of interest (ROIs were calculated. The diameters of the inhibition halos for 99mTc-CFT were 27.16 ± 0.23 and 27.17 ± 0.20 for S.aureus and E.coli, respectively, while those for the unlabeled CFT were 30.4 ± 0.33 and 29.43 ± 0.26, respectively. The results for the biodistribution of 99mTc-CFT in infected animals furnished a ratio of 1.97 ± 0.31, 2.10 ± 0.42 and 2.01 ± 0.42 for cpm-target/cpm-no target for the one, two and six-hour periods, respectively. The images showed a clear uptake of labeled antibiotic (99mTc-CFT by the infectious site during the experiment. The results attest to the viability of producing a kit with 99m technetium-labeled ceftizoxime for the investigation of infectious processes.O objetivo deste trabalho foi preparar um kit de Tc

    The development of kits for Total PSA assay has shown promising results. All essential components of the assay were prepared with reproducibility and used to optimize the assay. By choosing two steps method, we could avoid the hook effect and obtain satisfactory Q.C. parameters of the standard curve i.e. blank = 0.8%, maximum binding = 65%. If reference material for calibration of the standard is agree upon, the validation could then be carried out with total confidence. Our final goal is to reduce the step of incubation to just one step with no interference from hook effect

    Stenosis of arteriovenous (A-V) fistulae secondary to neointimal hyperplasia (NIH) compromises dialysis delivery, which worsens patients' quality of life and increases medical costs associated with the maintenance of vascular accesses. In the present study, we evaluated the role of the receptor tyrosine kinase c-Kit in A-V fistula neointima formation. Initially, c-Kit was found in the neointima and adventitia of human brachiobasilic fistulae, whereas it was barely detectable in control veins harvested at the time of access creation. Using the rat A-V fistula model to study venous vascular remodeling, we analyzed the spatial and temporal pattern of c-Kit expression in the fistula wall. Interestingly, c-Kit immunoreactivity increased with time after anastomosis, which concurred with the accumulation of cells in the venous intima. In addition, c-Kit expression in A-V fistulae was positively altered by chronic kidney failure conditions. Both blockade of c-Kit with imatinib mesylate (Gleevec) and inhibition of stem cell factor production with a specific short hairpin RNA prevented NIH in the outflow vein of experimental fistulae. In agreement with these data, impaired c-Kit activity compromised the development of NIH in A-V fistulae created in c-KitW/Wv mutant mice. These results suggest that targeting of the c-Kit signaling pathway may be an effective approach to prevent postoperative NIH in A-V fistulae. PMID:25186298

    Owing to peculiar properties of nanobody, including nanoscale size, robust structure, stable and soluble behaviors in aqueous solution, reversible refolding, high affinity and specificity for only one cognate target, superior cryptic cleft accessibility, and deep tissue penetration, as well as a sustainable source, it has been an ideal research tool for the development of sophisticated nanobiotechnologies. Currently, the nanobody has been evolved into versatile research and application tool kits for diverse biomedical and biotechnology applications. Various nanobody-derived formats, including the nanobody itself, the radionuclide or fluorescent-labeled nanobodies, nanobody homo- or heteromultimers, nanobody-coated nanoparticles, and nanobody-displayed bacteriophages, have been successfully demonstrated as powerful nanobiotechnological tool kits for basic biomedical research, targeting drug delivery and therapy, disease diagnosis, bioimaging, and agricultural and plant protection. These applications indicate a special advantage of these nanobody-derived technologies, already surpassing the "me-too" products of other equivalent binders, such as the full-length antibodies, single-chain variable fragments, antigen-binding fragments, targeting peptides, and DNA-based aptamers. In this review, we summarize the current state of the art in nanobody research, focusing on the nanobody structural features, nanobody production approach, nanobody-derived nanobiotechnology tool kits, and the potentially diverse applications in biomedicine and biotechnology. The future trends, challenges, and limitations of the nanobody-derived nanobiotechnology tool kits are also discussed.

    Modern day sensor network technology has shown great promise to transform environmental data collection. However, despite the promise, these systems have remained the purview of the engineers and computer scientists who design them rather than a useful tool for the environmental scientists who need them. SensorKit is conceived of as a way to make wireless sensor networks accessible to The People: it is an advanced, powerful tool for sensor data collection that does not require advanced technological know-how. We are aiming to make wireless sensor networks for environmental science as simple as setting up a standard home computer network by providing simple, tested configurations of commercially-available hardware, free and easy-to-use software, and step-by-step tutorials. We designed and built SensorKit using a simplicity-through-sophistication approach, supplying users a powerful sensor to database end-to-end system with a simple and intuitive user interface. Our objective in building SensorKit was to make the prospect of using environmental sensor networks as simple as possible. We built SensorKit from off the shelf hardware components, using the Compact RIO platform from National Instruments for data acquisition due to its modular architecture and flexibility to support a large number of sensor types. In SensorKit, we support various types of analog, digital and networked sensors. Our modular software architecture allows us to abstract sensor details and provide users a common way to acquire data and to command different types of sensors. SensorKit is built on top of the Sensor Processing and Acquisition Network (SPAN), a modular framework for acquiring data in the field, moving it reliably to the scientist institution, and storing it in an easily-accessible database. SPAN allows real-time access to the data in the field by providing various options for long haul communication, such as cellular and satellite links. Our system also features reliable data storage

    2017-10-01

    Overexpression of KIT is one of the mechanisms that contributes to imatinib resistance in KIT mutation-driven tumors. Here, the mechanism underlying this overexpression of KIT was investigated using an imatinib-sensitive canine mast cell tumor (MCT) line CoMS, which has an activating mutation in KIT exon 11. A KIT-overexpressing imatinib-resistant subline, rCoMS1, was generated from CoMS cells by their continuous exposure to increasing concentrations of imatinib. Neither a secondary mutation nor upregulated transcription of KIT was detected in rCoMS1 cells. A decrease in KIT ubiquitination, a prolonged KIT life-span, and KIT overexpression were found in rCoMS1 cells. These events were suppressed by withdrawal of imatinib and were re-induced by re‑treatment with imatinib. These findings suggest that imatinib elicited overexpression of KIT via suppression of its ubiquitination. These results also indicated that imatinib-induced overexpression of KIT in rCoMS1 cells was not a permanently acquired feature but was a reversible response of the cells. Moreover, the pan deubiquitinating enzyme inhibitor PR619 prevented imatinib induction of KIT overexpression, suggesting that the imatinib-induced decrease in KIT ubiquitination could be mediated by upregulation and/or activation of deubiquitinating enzyme(s). It may be possible that a similar mechanism of KIT overexpression underlies the acquisition of imatinib resistance in some human tumors that are driven by KIT mutation.

  19. Development of a didactic electrophoresis kit for the practical teaching of Molecular Biology in basic and higher education

    Full Text Available The advances in the biotechnology area imposes a new reality, creating products that are present in our daily lives, affecting directly or indirectly the population. Applications related to DNA technologies in the industry, agriculture and medicine have social, ethical and ecological implications, in addition to the human health consequences. So, it is necessary that the public is informed of progress in this area of knowledge. In order to create an alternative method to stimulate students in scientific careers and improve the learning of biotechnology and molecular biology, we developed a junior research project with high school students of the Federal Institute of Education, Science and Technology of the Espírito Santo (Brazil, which aimed the construction of a teaching kit of electrophoresis. Electrophoresis is a technique widely used in molecular biology laboratories, which is applied to separate molecules such as proteins and nucleic acids. In this technique, electrically charged molecules are exposed to an electric field and then they move towards the oppositely charged pole, being deposited in specific points of the matrix used. The kit built in this work consists of a source of 70 V, and accessories and reagents that are readily available and present low cost and low risk to the health of users. The use of the kit allowed for electrophoretic assays with nucleic acids and food dyes. The kit also contains a printed material that addresses issues about DNA technology and the device user’s guide with suggestions of experiences to simulate paternity test, virus identification and others. The application of the teaching kit in practical classes with students and teachers of basic education showed that the activity was effective in reducing the number of errors in answers contained in a questionnaire related to the electrophoresis. Moreover, biology teachers evaluated the printed material of the didactic kit and 75% of them classified the

    Operating rooms require a storage, dispensing and accounting system for restricted drugs which satisfies narcotics control authorities and is compatible with efficient care of patients. We describe narcotic kits containing fentanyl-morphine-midazolam, alfentanil-midazolam and sufentanil-midazolam, for general operating rooms, and two kits with larger quantities of fentanyl and sufentanil for cardiac operating rooms. The container for each kit is a video cassette holder which has a foam-rubber liner with sculpted depressions for each ampoule. Sealed kits are delivered each morning from pharmacy to the locked narcotics cupboard in the recovery room. On request, the recovery room nurse unlocks the cupboard and the anaesthetist signs out the required kit(s) for the day. A drug utilization form is enclosed with each kit, on which the anaesthetist records the amount of drug administered to each patient, and before returning the kit to the locked narcotics cupboard, the total amount of each drug used, discarded, and returned. Used kits are collected the following morning by a pharmacy technician who reconciles the contents and drug form of each kit. More than 40 staff anaesthetists and a similar number of residents have used the system for seven years, during which time 130,000 patients have passed through the operating rooms. Detection of one case of drug diversion by a staff anaesthetist was made partly by the control system, but mainly by behavioural changes. The system is simple, inexpensive, and effective and has been well received by the departments of pharmacy, anaesthesia, and nursing.

    This article includes supplemental data. Please visit http://www.fasebj.org to obtain this information.Multiple recent publications on RNA sequencing (RNA-seq) have demonstrated the power of next-generation sequencing technologies in whole-transcriptome analysis. Vendor-specific protocols used for RNA library construction often require at least 100 ng total RNA. However, under certain conditions, much less RNA is available for library construction. In these cases, effective transcriptome profiling requires amplification of subnanogram amounts of RNA. Several commercial RNA amplification kits are available for amplification prior to library construction for next-generation sequencing, but these kits have not been comprehensively field evaluated for accuracy and performance of RNA-seq for picogram amounts of RNA. To address this, 4 types of amplification kits were tested with 3 different concentrations, from 5 ng to 50 pg, of a commercially available RNA. Kits were tested at multiple sites to assess reproducibility and ease of use. The human total reference RNA used was spiked with a control pool of RNA molecules in order to further evaluate quantitative recovery of input material. Additional control data sets were generated from libraries constructed following polyA selection or ribosomal depletion using established kits and protocols. cDNA was collected from the different sites, and libraries were synthesized at a single site using established protocols. Sequencing runs were carried out on the Illumina platform. Numerous metrics were compared among the kits and dilutions used. Overall, no single kit appeared to meet all the challenges of small input material. However, it is encouraging that excellent data can be recovered with even the 50 pg input total RNA.

    The quantification of human genomic DNA is a necessary first step in the DNA casework sample analysis workflow. DNA quantification determines optimal sample input amounts for subsequent STR (short tandem repeat) genotyping procedures, as well as being a useful screening tool to identify samples most likely to provide probative genotypic evidence. To better mesh with the capabilities of newest-generation STR analysis assays, the Quantifiler(®) HP and Quantifiler(®) Trio DNA Quantification Kits were designed for greater detection sensitivity and more robust performance with samples that contain PCR inhibitors or degraded DNA. The new DNA quantification kits use multiplex TaqMan(®) assay-based fluorescent probe technology to simultaneously quantify up to three human genomic targets, allowing samples to be assessed for total human DNA, male contributor (i.e., Y-chromosome) DNA, as well as a determination of DNA degradation state. The Quantifiler HP and Trio Kits use multiple-copy loci to allow for significantly improved sensitivity compared to earlier-generation kits that employ single-copy target loci. The kits' improved performance provides better predictive ability for results with downstream, newest-generation STR assays, and their shortened time-to-result allows more efficient integration into the forensic casework analysis workflow.

    2010-01-01

    The Math Description Engine Software Development Kit (MDE SDK) can be used by software developers to make computer-rendered graphs more accessible to blind and visually-impaired users. The MDE SDK generates alternative graph descriptions in two forms: textual descriptions and non-verbal sound renderings, or sonification. It also enables display of an animated trace of a graph sonification on a visual graph component, with color and line-thickness options for users having low vision or color-related impairments. A set of accessible graphical user interface widgets is provided for operation by end users and for control of accessible graph displays. Version 1.0 of the MDE SDK generates text descriptions for 2D graphs commonly seen in math and science curriculum (and practice). The mathematically rich text descriptions can also serve as a virtual math and science assistant for blind and sighted users, making graphs more accessible for everyone. The MDE SDK has a simple application programming interface (API) that makes it easy for programmers and Web-site developers to make graphs accessible with just a few lines of code. The source code is written in Java for cross-platform compatibility and to take advantage of Java s built-in support for building accessible software application interfaces. Compiled-library and NASA Open Source versions are available with API documentation and Programmer s Guide at http:/ / prim e.jsc.n asa. gov.

    2010-07-06

    A decontamination formulation and method of making that neutralizes the adverse health effects of both chemical and biological compounds, especially chemical warfare (CW) and biological warfare (BW) agents, and toxic industrial chemicals. The formulation provides solubilizing compounds that serve to effectively render the chemical and biological compounds, particularly CW and BW compounds, susceptible to attack, and at least one reactive compound that serves to attack (and detoxify or kill) the compound. The formulation includes at least one solubilizing agent, a reactive compound, a sorbent additive, and water. A highly adsorbent sorbent additive (e.g., amorphous silica, sorbitol, mannitol, etc.) is used to "dry out" one or more liquid ingredients into a dry, free-flowing powder that has an extended shelf life, and is more convenient to handle and mix in the field. The formulation can be pre-mixed and pre-packaged as a multi-part kit system, where one or more of the parts are packaged in a powdered, granulated form for ease of handling and mixing in the field.

    Synthetic fuels from biomass may contribute to the future motor fuel supply to a considerable extent. To overcome the logistical hurdles connected with the industrial use of large quantities of biomass, the de-central/central bioliq {sup registered} concept has been developed. It is based on a regional pre-treatment of biomass for energy densification by fast pyrolysis. The intermediate referred to as biosyncrude enables an economic long-range transportation. Collected from a number of those pyrolysis plants, the biosyncrude is converted into synthesis gas, which is cleaned, conditioned and further converted to fuels or chemicals in a central plant of reasonable industrial size. Gasification is performed in an entrained flow gasifier at pressures adjusted to the subsequent chemical synthesis. For increased fuel flexibility and utilization of ash rich feed materials, the gasifier is equipped with a cooling screen operated in slagging mode. At the Karlsruhe Institute of Technology, KIT, a bioliq {sup registered} pilot plant has been erected for demonstration of the whole process chain. The 2 MW{sub th} fast pyrolysis plant is in operation since 2009; the 5 MW{sub th} / 80 bars gasifier, the hot gas cleaning section and the gasoline synthesis via DME were erected in 2011/12. Commissioning of that plant complex was completed in 2013. (orig.)

    The Physiome Project was officially launched in 1997 and has since brought together teams from around the world to work on the development of a computational framework for the modeling of the human body. At the European level, this effort is focused around patient-specific solutions and is known as the Virtual Physiological Human (VPH) Initiative.Such modeling is both multiscale (in space and time) and multiphysics. This, therefore, requires careful interaction and collaboration between the teams involved in the VPH/Physiome effort, if we are to produce computer models that are not only quantitative, but also integrative and predictive.In that context, several technologies and solutions are already available, developed both by groups involved in the VPH/Physiome effort, and by others. They address areas such as data handling/fusion, markup languages, model repositories, ontologies, tools (for simulation, imaging, data fitting, etc.), as well as grid, middleware, and workflow.Here, we provide an overview of resources that should be considered for inclusion in the VPH/Physiome ToolKit (i.e., the set of tools that addresses the needs and requirements of the Physiome Project and VPH Initiative) and discuss some of the challenges that we are still facing.

    Donnelly, Judy; Magnani, Nancy; Robinson, Kathleen

    2016-09-01

    The Next Generation Science Standards (NGSS) and renewed emphasis on STEM education in the U.S. have resulted in the development of many educational kits for teaching science in general and optics in particular. Many teachers do not have funding to purchase kits and practical experience has shown that even costly kits can have poorly written and misleading instructions and may include experiments that would not work in a classroom. Dumpster Optics lessons are designed to use inexpensive, commonly found materials. All lessons have been field-tested with students. We will describe the development of the lessons, provide examples of field testing experiences and outline possible future activities.

    died from day 1-7, and only ~5% in RES-3. The risk of dying was approx. 4 times higher for a kit live-born into the one resource environment. RES-3 females were building better nests and stayed in the nest box longer around parturition than RES-1, which could explain the higher mortality in this group....... We discriminated between stillborn and live-born kits dying early using autopsy. The access to more than one resource (RES-3) of nest building material had a profound effect on kit mortality in the firs week of life compared to access to straw only (χ²(1) = 13.7, P

    Full Text Available BACKGROUND: Whole blood expression profiling is frequently performed using PAXgene (Qiagen or Tempus (Life Technologies tubes. Here, we compare 6 novel generation RNA isolation protocols with respect to RNA quantity, quality and recovery of mRNA and miRNA. METHODS: 3 PAXgene and 3 Tempus Tubes were collected from participants of the LIFE study with (n = 12 and without (n = 35 acute myocardial infarction (AMI. RNA was extracted with 4 manual protocols from Qiagen (PAXgene Blood miRNA Kit, Life Technologies (MagMAX for Stabilized Blood Tubes RNA Isolation Kit, and Norgen Biotek (Norgen Preserved Blood RNA Purification Kit I and Kit II, and 2 (semi-automated protocols on the QIAsymphony (Qiagen and MagMAX Express-96 Magnetic Particle Processor (Life Technologies. RNA quantity and quality was determined. For biological validation, RNA from 12 representative probands, extracted with all 6 kits (n = 72, was reverse transcribed and mRNAs (matrix metalloproteinase 9, arginase 1 and miRNAs (miR133a, miR1, shown to be altered by AMI, were analyzed. RESULTS: RNA yields were highest using the Norgen Kit I with Tempus Tubes and lowest using the Norgen Kit II with PAXgene. The disease status was the second major determinant of RNA yields (LIFE-AMI 11.2 vs. LIFE 6.7 µg, p<0.001 followed by the choice of blood collection tube. (Semi-automation reduced overall RNA extraction time but did not generally reduce hands-on-time. RNA yields and quality were comparable between manual and automated extraction protocols. mRNA expression was not affected by collection tubes and RNA extraction kits but by RT/qPCR reagents with exception of the Norgen Kit II, which led to mRNA depletion. For miRNAs, expression differences related to collection tubes (miR30b, RNA isolation (Norgen Kit II, and RT/qRT reagents (miR133a were observed. CONCLUSION: We demonstrate that novel generation RNA isolation kits significantly differed with respect to RNA recovery and affected

    Hammen, David G.; Moebes, Travis A.; Shelton, Robert O.; Savely, Robert T.

    1993-01-01

    During Space Shuttle operations, Mission Control personnel monitor numerous mission-critical systems such as electrical power; guidance, navigation, and control; and propulsion by means of paper strip chart recorders. For example, electrical power controllers monitor strip chart recorder pen traces to identify onboard electrical equipment activations and deactivations. Recent developments in pattern recognition technologies coupled with new capabilities that distribute real-time Shuttle telemetry data to engineering workstations make it possible to develop computer applications that perform some of the low-level monitoring now performed by controllers. The number of opportunities for such applications suggests a need to build a pattern recognition tool kit to reduce software development effort through software reuse. We are building pattern recognition applications while keeping such a tool kit in mind. We demonstrated the initial prototype application, which identifies electrical equipment activations, during three recent Shuttle flights. This prototype was developed to test the viability of the basic system architecture, to evaluate the performance of several pattern recognition techniques including those based on cross-correlation, neural networks, and statistical methods, to understand the interplay between an advanced automation application and human controllers to enhance utility, and to identify capabilities needed in a more general-purpose tool kit.

    Immunoradiometric assay for CA 130 was fundamentally and clinically evaluated using a commercially available D-7111 kit. Incubation time was 4 hr with the present CA 133 kit as compared with 16 - 24 hr with conventional CA 125 kit. Laboratory performance of CA 130 kit was satisfactory for standard curve, reproducibility, and recovery test. There was well correlation between the present CA 130 kit and CA 125 kit (r = 0.931). The concentration of CA 130 in the serum was significantly higher in healthy women than men (17.3 +- 10.5 U/ml vs 9.6 +- 5.1 U/ml). Serum CA 130 levels tended to decrease with aging, regardless of sex. These levels were changeable with menstrual cycle ; i.e., these were significantly higher during menstrual phase (24.2 +- 9.0 U/ml) and significantly lower during ovulatory phase (10.9 +- 2.4 U/ml) and during menopause (12.1 +- 3.4 U/ml). Cut off serum CA 130 levels were defined as 20 U/ml for men and 38 U/ml for women. Positive rate for CA 130 was the highest in cases of ovarian cancer (80 %), followed by endometrial cancer (50 %), pancreatic cancer (47 %), benign ovarian tumor (44 %), and lung cancer (39 %).

    The c-kit receptor is responsible for transmission of promigration signals to melanocytes; its downregulation may be involved in malignant progression of human melanocytic neoplasms. Expression of this receptor has not been examined in normal or neoplastic melanocytes from dogs. In this study, 14 benign dermal and 61 malignant mucosal melanocytic tumors were examined for c-kit (KIT) expression. Sites of the mucosal melanomas were gingiva (not further specified; n = 30), buccal gingiva (n = 6), soft palate (n = 4), hard palate (n = 5), tongue (n = 7), lip (n = 6), and conjunctiva (n = 3). Melan A was expressed in all 14 dermal melanocytomas and in 59 of 61 (96.7%) tumors from oral or conjunctival mucosa, confirming melanocytic origin. C-kit receptor expression was strong and diffuse throughout the cytoplasm in all 14 dermal melanocytomas and was identified in basilar mucosal melanocytes over submucosal neoplasms (27 of 61, 44.3%), junctional (neoplastic) melanocytes (17 of 61, 27.9%), and, less commonly, neoplastic melanocytes of the subepithelial tumors (6 of 61, 9.8%). KIT expression anywhere within the resected melanomas correlated with significantly longer survival. These results suggest that c-kit receptor expression may be altered in canine melanomas and may have potential as a prognostic indicator for mucosal melanomas.

    2002-01-01

    The Coca-Cola travel health kit has been used for about one decade for international travelers and required evaluation to see if the items contained were appropriate for the employees. Two hundred thirty-four travelers were sampled and filled out a voluntary survey including questions about demographic information, travel history, and usage and value of the contents of the travel health kit. One hundred eighty-one surveys were returned; 65% of the respondents were male, and the majority of travelers were between the ages of 36 and 45 years. The most useful items were analgesics and medications used for gastrointestinal problems. In general, the items identified as being the least useful were those requiring specialized use by a medical practitioner, such as needles and syringes. Suggestions of items to be added to the kit included vitamins, cough drops, sleep aids, and eye drops. A surprising result that Coca-Cola employees expressed the desire for brand name rather than generic items. Evaluation of the Coca-Cola Company travel health kit revealed it to be very useful to most corporate travelers. Suggestions that were made will be taken into consideration in designing a new kit, and consideration is being given to whether a basic travel health kit should be provided to which travelers can add other items depending on their personal needs.

  1. Radotinib induces high cytotoxicity in c-KIT positive acute myeloid leukemia cells.

    2017-06-05

    Previously, we reported that radotinib, a BCR-ABL1 tyrosine kinase inhibitor, induced cytotoxicity in acute myeloid leukemia (AML) cells. However, the effects of radotinib in the subpopulation of c-KIT-positive AML cells were unclear. We observed that low-concentration radotinib had more potent cytotoxicity in c-KIT-positive cells than c-KIT-negative cells from AML patients. To address this issue, cell lines with high c-KIT expression, HEL92.1.7, and moderate c-KIT expression, H209, were selected. HEL92.1.7 cells were grouped into intermediate and high c-KIT expression populations. The cytotoxicity of radotinib against the HEL92.1.7 cell population with intermediate c-KIT expression was not different from that of the population with high c-KIT expression. When H209 cells were grouped into c-KIT expression-negative and c-KIT expression-positive populations, radotinib induced cytotoxicity in the c-KIT-positive population, but not the c-KIT-negative population. Thus, radotinib induces cytotoxicity in c-KIT-positive cells, regardless of the c-KIT expression intensity. Therefore, radotinib induces significant cytotoxicity in c-KIT-positive AML cells, suggesting that radotinib is a potential target agent for the treatment of c-KIT-positive malignancies including AML.

  4. Quantitation of next generation sequencing library preparation protocol efficiencies using droplet digital PCR assays - a systematic comparison of DNA library preparation kits for Illumina sequencing.

    Aigrain, Louise; Gu, Yong; Quail, Michael A

    2016-06-13

    The emergence of next-generation sequencing (NGS) technologies in the past decade has allowed the democratization of DNA sequencing both in terms of price per sequenced bases and ease to produce DNA libraries. When it comes to preparing DNA sequencing libraries for Illumina, the current market leader, a plethora of kits are available and it can be difficult for the users to determine which kit is the most appropriate and efficient for their applications; the main concerns being not only cost but also minimal bias, yield and time efficiency. We compared 9 commercially available library preparation kits in a systematic manner using the same DNA sample by probing the amount of DNA remaining after each protocol steps using a new droplet digital PCR (ddPCR) assay. This method allows the precise quantification of fragments bearing either adaptors or P5/P7 sequences on both ends just after ligation or PCR enrichment. We also investigated the potential influence of DNA input and DNA fragment size on the final library preparation efficiency. The overall library preparations efficiencies of the libraries show important variations between the different kits with the ones combining several steps into a single one exhibiting some final yields 4 to 7 times higher than the other kits. Detailed ddPCR data also reveal that the adaptor ligation yield itself varies by more than a factor of 10 between kits, certain ligation efficiencies being so low that it could impair the original library complexity and impoverish the sequencing results. When a PCR enrichment step is necessary, lower adaptor-ligated DNA inputs leads to greater amplification yields, hiding the latent disparity between kits. We describe a ddPCR assay that allows us to probe the efficiency of the most critical step in the library preparation, ligation, and to draw conclusion on which kits is more likely to preserve the sample heterogeneity and reduce the need of amplification.

    Targeting oncogenic kinase drivers with small-molecule inhibitors can have marked therapeutic benefit, especially when administered to an appropriate genomically defined patient population. Cancer genomics and mechanistic studies have revealed that heterogeneous mutations within a single kinase can result in various mechanisms of kinase activation. Therapeutic benefit to patients can best be optimized through an in-depth understanding of the disease-driving mutations combined with the ability to match these insights to tailored highly selective drugs. This rationale is presented for BLU-285, a clinical stage inhibitor of oncogenic KIT and PDGFRA alterations, including activation loop mutants that are ineffectively treated by current therapies. BLU-285, designed to preferentially interact with the active conformation of KIT and PDGFRA, potently inhibits activation loop mutants KIT D816V and PDGFRA D842V with subnanomolar potency and also inhibits other well-characterized disease-driving KIT mutants both in vitro and in vivo in preclinical models. Early clinical evaluation of BLU-285 in a phase 1 study has demonstrated marked activity in patients with diseases associated with KIT (aggressive systemic mastocytosis and gastrointestinal stromal tumor) and PDGFRA (gastrointestinal stromal tumor) activation loop mutations.

    No study has comprehensively evaluated the performance of 28S nrDNA and ITS sequencing, commercial biochemical test kits, MALDI-TOF MS platforms, and the emerging rep-PCR DNA fingerprinting technology using a cohort of yeast strains collected from a clinical microbiology laboratory. In this study, using 71 clinically important yeast isolates (excluding Candida albicans) collected from a single centre, we determined the concordance of 28S nrDNA and ITS sequencing and evaluated the performance of two commercial test kits, two MALDI-TOF MS platforms, and rep-PCR DNA fingerprinting. 28S nrDNA and ITS sequencing showed complete agreement on the identities of the 71 isolates. Using sequencing results as the standard, 78.9% and 71.8% isolates were correctly identified using the API 20C AUX and Vitek 2 YST ID Card systems, respectively; and 90.1% and 80.3% isolates were correctly identified using the Bruker and Vitek MALDI-TOF MS platforms, respectively. Of the 18 strains belonging to the Candida parapsilosis species complex tested by DiversiLab automated rep-PCR DNA fingerprinting, all were identified only as Candida parapsilosis with similarities ≥93.2%, indicating the misidentification of Candida metapsilosis and Candida orthopsilosis. However, hierarchical cluster analysis of the rep-PCR DNA fingerprints of these three species within this species complex formed three different discrete clusters, indicating that this technology can potentially differentiate the three species. To achieve higher accuracies of identification, the databases of commercial biochemical test kits, MALDI-TOF MS platforms, and DiversiLab automated rep-PCR DNA fingerprinting needs further enrichment, particularly for uncommonly encountered yeast species. © The Author 2017.

    The Science Directorate (SD) at NASA Langley Research Center provides many opportunities to involve students, faculty, researchers, and the citizen science community in real world science. The SD Education Team collaborates with the education community to bring authentic Earth science practices and real-world data into the classroom, provide the public with unique NASA experiences, engaging activities, and advanced technology, and provide products developed and reviewed by science and education experts. Our goals include inspiring the next generation of Science, Technology, Engineering and Mathematics (STEM) professionals and improving STEM literacy by providing innovative participation pathways for educators, students, and the public. The SD Education Team has developed Atmosphere activity kits featuring cloud and aerosol learning activities with a foundation in NASA Earth Science Missions, the Next Generation Science Standards, and The GLOBE Program's Elementary Storybooks. Through cloud kit activities, students will learn how to make estimates from observations and how to categorize and classify specific cloud properties, including cloud height, cloud cover, and basic cloud types. The purpose of the aerosol kit is to introduce students to aerosols and how they can affect the colors we see in the sky. Students will engage in active observation and reporting, explore properties of light, and model the effects of changing amounts/sizes or aerosols on sky color and visibility. Learning activity extensions include participation in ground data collection of environmental conditions and comparison and analysis to related NASA data sets, including but not limited to CERES, CALIPSO, CloudSat, and SAGE III on ISS. This presentation will provide an overview of multiple K-6 NASA Earth Science hands-on activities and free resources will be available.

  12. Kit for performing puncture test on HV insulators

    Energy Technology Data Exchange (ETDEWEB)

    Oliveira, O.B.; Mello, D.R.; Cerqueira, W.R.; Alvarenga, E. [CEPEL, Rio de Janeiro, RJ (Brazil)

    1997-12-31

    A compact and easy way to handle puncture tests in high voltage electrical equipment was introduced. The characteristics of the main components of a new type of kit and some examples of its application were described. It is necessary to perform puncture tests on insulators used to support line conductors and to keep the necessary clearances between conductors and the tower. A puncture test is conducted by stressing the insulator with steep and short duration high voltage impulses. The special kit to handle the puncture tests was developed at CEPEL`s high voltage laboratory for performing tests up to 500 kV peak. The kit is composed of dry and compressed air insulated sphere gap, a very fast resistive divider and a structure which makes it easier to connect to conventional high voltage impulse generators. 3 refs., 1 tab., 7 figs.

  13. Determination of stannous tin in radiopharmaceutical cold kits

    International Nuclear Information System (INIS)

    Farrant, A.J.

    1979-01-01

    Two methods for determining stannous tin in 'cold kits', used for the preparation of Tc-99m labelled radiopharmaceuticals, have been developed. Both are based on the direct titration of the Sn2 in solution. In the first method titration is with N-bromosuccinimide. Of the materials commonly used as cold kits only albumin has been found to interfere with the determination. The second method is a standard iodometric titration in which starch is used as indicator. None of the materials tested interfere with this procedure. The N-bromosuccinimide method is the method of choice as the re-agent, a solid, can be used without prior standardization. Iodine solution must be standardized daily. The paper describes in detail the methods used and gives examples of kits in which the Sn2 levels have been determined using the described procedures

    1986-01-01

    By the use of solid state nuclear track detectors (SSNTDs) one may carry out several useful and impressive educational experiments and demonstrations to illustrate different phenomena when teaching of nuclear physics. Realizing this situation the authors have published, since 1970, reports on several experiments for teaching demonstrations. Based on the authors instructions, a factory in Hungary (TANFRT, National Manufacturers and Suppliers of School Equipment, Budapest) constructed a kit for the use of nuclear track detectors in teaching. The portable kit contains the following items: alpha-emitting weak sources, solid state nuclear track detectors (unirradiated, irradiated, unetched and etched sheets), simple tools for carrying out experiments (facilities for irradiation and etching, etc.), slides showing photos of typical etch-tracks of light and heavy nuclei, user manual. By the help of the kit both pupils and teachers can perform various useful experiments and/or demonstrations. (author)

    1987-01-01

    A commercially available radioimmunoassay kit (Yamasa) for parathyroid hormone (PTH) is the midregion-specific assay system. Fundamental study of the PTH kit gave favorable results for specificity, reproducibility, dilution, and recovery. The serum PTH concentration was detectable among all 41 normal volunteers. The upper and lower limits of normal for PTH in serum were found to be 600 pg/ml and 184 pg/ml, respectively. PTH values were high for chronic renal failure (6/7) and primary hyperparathyroidism (41/41), and low for malignancy associated with hypercalcemia (5/25). It seems possible to discriminate hypercalcemic from normal subjects. The serum PTH concentration from the present assay system was significantly correlated with that from conventional carboxyl-terminal PTH, midregion PTH, amino-terminal PTH, and (1 - 84) PTH assay systems. The results indicate the potential of the Yamasa kit in evaluating calcium metabolism, as well as in detecting the presence of secondary hyperparathyroidism. (Namekawa, K.)

    2016-09-01

    The U.S. National Optical Astronomy Observatory's Education and Public Outreach group has produced a Quality Lighting Teaching (QLT) Kit, as an outcome of the International Year of Light 2015. The kits are designed around problem-based learning scenarios. The kit's six activities allow students to address real lighting problems that relate to wildlife, sky glow, aging eyes, energy consumption, safety, and light trespass. The activities are optimized for 11-14 year olds but can be expanded to younger and older. Most of the activities can be done within in a few minutes with the exception of the Energy Activity. The activities can be done during class or afterschool and as stations (that the students rotate through) or as stand-alones (one at a time). All aspects of the program are as ready-for-use. Everything you need for the six activities is included in the kit. Tutorial videos (on the program's webpage) have been created on how to do the activities. They can be found on the webpage, www.noao.edu/education/qltkit.php. Fourteen Google+ Hangouts on Air have been offered, addressing questions on the activities and logistics. Assessments (in the form of pre- and post-surveys for the students and as post-surveys for the instructors) provide learning outcomes and improvements. Eighty-nine out of 100 kits have been distributed to SPIE, OSA, CIE, IDA and the IAU in 31 countries. The QLT Kit is a stepping-stone to bring awareness to the (younger) public on how quality lighting locally can redress issues like light pollution globally.

    1979-01-01

    The determination of serum ferritin levels may be of diagnostic importance in medicine. To establish whether values obtained using a commercially available kit (Ramco) were adequate for this purpose, a comparison was undertaken using a two-site immunoradiometric assay that had been developed and standardized in our laboratories. Over the range 6μg/l to greater than 2 000 μg/l there was a correlation coefficient between the two methods of 0,8284 (P smaller than 0,001). It is concluded that the Ramco kit is suitable for use in clinical practice

    2017-05-01

    Massively Parallel (Next Generation) Sequencing (MPS) technologies have recently been proven useful and successful in typing various markers relevant in forensic genetics, such as STRs, SNPs and mitochondrial genomes. Early studies investigated self-developed DNA libraries, commercially supplied kits are currently being made available to allow a smoother and gradual implementation of such technologies in forensic laboratories. The ForenSeq™ DNA Signature Prep Kit (Illumina, CA) is the first commercially available STR kit that can be used on the MiSeq FGx™ (Illumina, CA) benchtop high-throughput sequencer. This kit allows the simultaneous typing of 59 STRs and up to 172 SNPs in a single reaction and presents a short library preparation protocol adapted to contemporary forensic requirements. In this study, we evaluated the beta version of the ForenSeq DNA Signature Prep Kit MiSeq FGx system by investigating reproducibility, sensitivity, mixtures, concordance, casework-type and aDNA samples and found it to perform successfully, proving to be a robust method for future forensic applications. MPS brings the possibility of complex multiplexing, high sensitivity and sequencing resolution to forensics; however, the need for consensual directions on databasing, data storage and nomenclature must be taken into consideration.

  2. Reliable and accurate CD4+ T cell count and percent by the portable flow cytometer CyFlow MiniPOC and "CD4 Easy Count Kit-Dry", as revealed by the comparison with the gold standard dual platform technology.

    Directory of Open Access Journals (Sweden)

    Milena Nasi

    Full Text Available An accurate and affordable CD4+ T cells count is an essential tool in the fight against HIV/AIDS. Flow cytometry (FCM is the "gold standard" for counting such cells, but this technique is expensive and requires sophisticated equipment, temperature-sensitive monoclonal antibodies (mAbs and trained personnel. The lack of access to technical support and quality assurance programs thus limits the use of FCM in resource-constrained countries. We have tested the accuracy, the precision and the carry-over contamination of Partec CyFlow MiniPOC, a portable and economically affordable flow cytometer designed for CD4+ count and percentage, used along with the "CD4% Count Kit-Dry".Venous blood from 59 adult HIV+ patients (age: 25-58 years; 43 males and 16 females was collected and stained with the "MiniPOC CD4% Count Kit-Dry". CD4+ count and percentage were then determined in triplicate by the CyFlow MiniPOC. In parallel, CD4 count was performed using mAbs and a CyFlow Counter, or by a dual platform system (from Beckman Coulter based upon Cytomic FC500 ("Cytostat tetrachrome kit" for mAbs and Coulter HmX Hematology Analyzer (for absolute cell count.The accuracy of CyFlow MiniPOC against Cytomic FC500 showed a correlation coefficient (CC of 0.98 and 0.97 for CD4+ count and percentage, respectively. The accuracy of CyFlow MiniPOC against CyFlow Counter showed a CC of 0.99 and 0.99 for CD4 T cell count and percentage, respectively. CyFlow MiniPOC showed an excellent repeatability: CD4+ cell count and percentage were analyzed on two instruments, with an intra-assay precision below ± 5% deviation. Finally, there was no carry-over contamination for samples at all CD4 values, regardless of their position in the sequence of analysis.The cost-effective CyFlow MiniPOC produces rapid, reliable and accurate results that are fully comparable with those from highly expensive dual platform systems.

  3. The problem of untested sexual assault kits: why are some kits never submitted to a crime laboratory?

    Science.gov (United States)

    Patterson, Debra; Campbell, Rebecca

    2012-07-01

    Victims of sexual assault are often advised to seek postassault medical care to have a forensic exam, which includes evidence collection (termed a sexual assault kit [SAK]). After the exam, law enforcement personnel are supposed to submit the SAK to a crime laboratory for analysis. However, recent media reports suggest that in many communities throughout the United States, thousands of SAKs are left untested. Few studies have examined the rate at which law enforcement submits SAKs to crime labs or the factors that may predict them to do so. Thus, the purpose of this exploratory study is twofold: (a) to examine the percentage of SAKs law enforcement submits to crime labs in cases in which a sexual assault nurse examiner (SANE) performed the exam with adult victims and (b) to explore whether assault and law enforcement characteristics predict whether SAKs are submitted to a crime lab. This study found that only 58.6% of the SAKs were submitted to the crime lab within a large Midwestern county. Using binary logistic regression, this study found that kits were significantly as likely to be submitted when there were documented physical (nonanogenital) injuries compared with kits that did not have documented physical injuries. In addition, kits that were handled by a law enforcement agency that had a high level of engagement with the SANE program were significantly as likely to be submitted as law enforcement agencies with a low or medium level of engagement. Kits were significantly less likely to be submitted when victims cleaned themselves after the sexual assault (e.g., bathing). No association was found between kit submission and the victim-offender relationship, suspected drug-facilitated sexual assault, anogenital injury, and when the victim consumed alcohol or drugs before the assault. This article concludes with a discussion of the implications for research and practice.

    2015-09-30

    This report gives documentation for using MeshKit’s Reactor Geometry (and mesh) Generator (RGG) GUI and also briefly documents other algorithms and tools available in MeshKit. RGG is a program designed to aid in modeling and meshing of complex/large hexagonal and rectilinear reactor cores. RGG uses Argonne’s SIGMA interfaces, Qt and VTK to produce an intuitive user interface. By integrating a 3D view of the reactor with the meshing tools and combining them into one user interface, RGG streamlines the task of preparing a simulation mesh and enables real-time feedback that reduces accidental scripting mistakes that could waste hours of meshing. RGG interfaces with MeshKit tools to consolidate the meshing process, meaning that going from model to mesh is as easy as a button click. This report is designed to explain RGG v 2.0 interface and provide users with the knowledge and skills to pilot RGG successfully. Brief documentation of MeshKit source code, tools and other algorithms available are also presented for developers to extend and add new algorithms to MeshKit. RGG tools work in serial and parallel and have been used to model complex reactor core models consisting of conical pins, load pads, several thousands of axially varying material properties of instrumentation pins and other interstices meshes.

The Proportional-Integral-Derivative (PID scheme was then used to compensate the error. This kit is equipped with a user interface to configure controller coefficients, select the set points, plot the actual ball position, and display parameter values. The user interface program runs on PC or notebook connected to microcontroller via serial communications. A questionnaire-based assessment about the use of this kit was conducted by 17 students taking the course, giving a rating value of 94.12%.

    1992-01-01

    The aim of this Resource Kit is to provide information, diagrams, overheads and classroom activities, set in an Australian context, to broaden and enrich the teaching of nuclear science from both technical and social science aspects. It has been written to address the the Australian secondary school syllabuses and reflects this in both its format and contents. Emphasis has been given to the applications of nuclear physics to our lives today, from new medical diagnostic techniques to efficient methods of monitoring our own environment. This Resource Kit is a valuable source of information not readily available to teachers from textbooks. It provides a unique opportunity to present the picture in Australia, making us all more aware of Australia's front line in Australia, making us all more aware of Australia's front line role in nuclear research. The kit is meant to be used in conjunction with current textbooks, to complement and enrich them. The kit begins with a review of the many applications of nuclear science in order to provide a broad concrete base to motivate students to discover more of the specific details of the basic discoveries contained in the later sections. Topics such as the Structure of the Atom, which are well documented in textbooks, have been approached in a more creative and less rigorous manner to give teachers a fresh approach to the topic. The kit is divided into 10 separate sections and presented in loose-leaf form to facilitate its use in the classroom. Diagrams are inserted into the text to clarify and enrich descriptions, as well as being provided at the back of each section as black line masters for photocopying and overhead projections. ills., tabs

    The ready availability and ease of use of kits for the measurement of serum lipids has greatly facilitated these measurements. In many cases it would be convenient to use these kits in the determination of lipid concentrations in tissues. The successful application of serum kits in tissue analysis requires that two important issues be considered. First, the solvent system for the extraction of the lipids and the solvent used for analysis by the kit must be compatible with the reactions in the kit. Second, the concentration range in the analyzed solution must be within the range for which the kit is used. We report here that lipids in liver and adipose tissues may be significantly underestimated by the use of some kits. We recommend that the use of kits for tissue analysis of lipids be validated for the specific analysis.

    Full Text Available Abstract Background KIT is a proto-oncogene involved in diverse neoplastic processes. Aberrant kinase activity of the KIT receptor has been targeted by tyrosine kinase inhibitor (TKI therapy in different neoplasias. In all the earlier studies, KIT expression was reported to be absent in meningiomas. However, we observed KIT mRNA expression in some meningioma cases. This prompted us to undertake its detailed analyses in meningioma tissues resected during 2008–2009. Methods Tumor tissues and matched peripheral blood samples collected from meningioma patients were used for detailed molecular analyses. KIT expression was ascertained immunohistochemically and validated by immunoblotting. KIT and KITLG transcript levels were discerned by reverse transcription quantitative real-time PCR (RT-qPCR. Similarly, KIT amplification and allele loss were assessed by quantitative real-time (qPCR and validated by fluorescence in situ hybridization (FISH on the neoplastic tissues. Possible alterations of the gene at the nucleotide level were analyzed by sequencing. Results Contrary to earlier reports, KIT expression, was detected immunohistochemically in 20.6% meningioma cases (n = 34. Receptor (KIT and ligand (KITLG transcripts monitored by RT-qPCR were found to co-express (p = 0.048 in most of the KIT immunopositive tumors. 1/7 KIT positive meningiomas showed allele loss corroborated by reduced FISH signal in the corresponding neoplastic tissue. Sequence analysis of KIT showed M541L substitution in exon 10, in one of the immunopositive cases. However, its biological consequence remains to be uncovered. Conclusions This study clearly demonstrates KIT over-expression in the human meningiomas. The data suggest that up-regulated KIT transcription (p  0.05, is a likely mechanism responsible for altered KIT expression. Thus, KIT is a potential candidate for detailed investigation in the context of meningioma pathogenesis.

    Although cardiac c-kit + cells are being tested in clinical trials, the circumstances that determine lineage differentiation of c-kit + cells in vivo are unknown. Recent findings suggest that endogenous cardiac c-kit + cells rarely contribute cardiomyocytes to the adult heart. We assessed whether various pathological stimuli differentially affect the eventual cell fates of c-kit + cells. We used single-cell sequencing and genetic lineage tracing of c-kit + cells to determine whether various pathological stimuli would result in different fates of c-kit + cells. Single-cell sequencing of cardiac CD45 - c-kit + cells showed innate heterogeneity, indicative of the existence of vascular and mesenchymal c-kit + cells in normal hearts. Cardiac pressure overload resulted in a modest increase in c-kit-derived cardiomyocytes, with significant increases in the numbers of endothelial cells and fibroblasts. Doxorubicin-induced acute cardiotoxicity did not increase c-kit-derived endothelial cell fates but instead induced cardiomyocyte differentiation. Mechanistically, doxorubicin-induced DNA damage in c-kit + cells resulted in expression of p53. Inhibition of p53 blocked cardiomyocyte differentiation in response to doxorubicin, whereas stabilization of p53 was sufficient to increase c-kit-derived cardiomyocyte differentiation. These results demonstrate that different pathological stimuli induce different cell fates of c-kit + cells in vivo. Although the overall rate of cardiomyocyte formation from c-kit + cells is still below clinically relevant levels, we show that p53 is central to the ability of c-kit + cells to adopt cardiomyocyte fates, which could lead to the development of strategies to preferentially generate cardiomyocytes from c-kit + cells. © 2017 American Heart Association, Inc.

  10. Gene Duplication of the zebrafish kit ligand and partitioning of melanocyte development functions to kit ligand a.

    Directory of Open Access Journals (Sweden)

    Keith A Hultman

    2007-01-01

    Full Text Available The retention of particular genes after the whole genome duplication in zebrafish has given insights into how genes may evolve through partitioning of ancestral functions. We examine the partitioning of expression patterns and functions of two zebrafish kit ligands, kit ligand a (kitla and kit ligand b (kitlb, and discuss their possible coevolution with the duplicated zebrafish kit receptors (kita and kitb. In situ hybridizations show that kitla mRNA is expressed in the trunk adjacent to the notochord in the middle of each somite during stages of melanocyte migration and later expressed in the skin, when the receptor is required for melanocyte survival. kitla is also expressed in other regions complementary to kita receptor expression, including the pineal gland, tail bud, and ear. In contrast, kitlb mRNA is expressed in brain ventricles, ear, and cardinal vein plexus, in regions generally not complementary to either zebrafish kit receptor ortholog. However, like kitla, kitlb is expressed in the skin during stages consistent with melanocyte survival. Thus, it appears that kita and kitla have maintained congruent expression patterns, while kitb and kitlb have evolved divergent expression patterns. We demonstrate the interaction of kita and kitla by morpholino knockdown analysis. kitla morphants, but not kitlb morphants, phenocopy the null allele of kita, with defects for both melanocyte migration and survival. Furthermore, kitla morpholino, but not kitlb morpholino, interacts genetically with a sensitized allele of kita, confirming that kitla is the functional ligand to kita. Last, we examine kitla overexpression in embryos, which results in hyperpigmentation caused by an increase in the number and size of melanocytes. This hyperpigmentation is dependent on kita function. We conclude that following genome duplication, kita and kitla have maintained their receptor-ligand relationship, coevolved complementary expression patterns, and that

    Full Text Available Zhiqiang Jiang, Jian Zhang, Zhi Li, Yingjun Liu, Daohai Wang, Guangsen Han Department of General Surgery, Affiliated Tumor Hospital, Zhengzhou University, Zhengzhou, People’s Republic of China Abstract: Numerous types of KIT mutations have been reported in gastrointestinal stromal tumors (GISTs; however, controversy still exists regarding their clinicopathological significance. In this study, we reviewed the publicly available literature to assess the data by a meta-analysis to characterize KIT mutations and different types of KIT mutations in prognostic prediction in patients with GISTs. Twenty-eight studies that included 4,449 patients were identified and analyzed. We found that KIT mutation status was closely correlated with size of tumors and different mitosis indexes, but not with tumor location. KIT mutation was also observed to be significantly correlated with tumor recurrence, metastasis, as well as the overall survival of patients. Interestingly, there was higher risk of progression in KIT exon 9-mutated patients than in exon 11-mutated patients. Five-year relapse-free survival (RFS rate was significantly higher in KIT exon 11-deleted patients than in those with other types of KIT exon 11 mutations. In addition, RFS for 5 years was significantly worse in patients bearing KIT codon 557–558 deletions than in those bearing other KIT exon 11 deletions. Our results strongly support the hypothesis that KIT mutation status is another evaluable factor for prognosis prediction in GISTs. Keywords: KIT, meta-analysis, prognosis, marker, therapy

    2013-10-01

    This study compared two newborn Cytomegalovirus (CMV) IgG antibody screening ELISA kits and evaluated the detection effectiveness of Abnova kit. CMV IgG antibodies were detected by both SeraQuest and Abnova kits from dried blood spot (DBS) samples of 488 newborn heel sticks. The detection abilities of these two kits were compared in different sample dilution concentrations. Relative detection effectiveness of the Abnova kit was defined by statistical method using the SeraQuest kit as a point of comparison. Compared to the SeraQuest screening test kit, the Abnova kit revealed a sensitivity of 98.9%, specificity of 78.6%, positive predictive value of 99.3%, negative predictive value of 68.8%, and the coincidence rate for these two screening test kits at 98.3%. The consistency check of both kits based on interpretation of the kappa statistic was relatively good. For the Abnova kit, the "area under the ROC curve" was 0.887, which indicates moderate accuracy. Abnova kit can be applied to newborn screening for congenital CMV infections. However, repeating the test for ambiguous results is suggested to increase the specificity and negative predictive value.

    Alleviation of symptoms associated with advanced illness and dying is a fundamental goal and core principle of palliative care. Little research exists regarding hospice programs' practices for prescribing, dispensing, and utilizing medication kits in the home for management of uncontrolled symptoms. We conducted a telephone survey of all 22 agencies in New Hampshire providing home hospice care. The survey inquired about the timing of medication kit ordering and availability, characteristics of prescribers and pharmacies, kit contents, costs, frequency of use, and perceived impact of kits. All programs' kits contained medications to treat pain and dyspnea, 81% for nausea and vomiting, and 76% for seizures. Eighty-six percent of agencies (18/21) reported that a medication within the kits was used in more than 50% of cases. Eighty-six percent reported the kits often averted hospital or emergency department visits. Oral, sublingual, and rectal routes of administration were common as was topical preparations of combination medications. Three programs included parenteral morphine in kits. Kits cost less than $50 for the majority of programs. Hospice programs commonly utilize kits containing prescription medications for the purpose of managing uncontrolled symptoms in the home. There is considerable variation in kit contents and practice. Programs believe that kits diminish emergency department visits and hospitalizations. Research is needed to more fully describe and study the outcomes of these practices.

    Monte Carlo (MC) methods are numerical simulation techniques that can be used to extend the scope of calibrations performed in in vivo monitoring laboratories. These methods allow calibrations to be carried out for a much wider range of body shapes and sizes than would be feasible using physical phantoms. Unfortunately, nowadays, this powerful technique is still used mainly in research institutions only. In 2013, EURADOS and the in vivo monitoring laboratory of Karlsruhe Institute of Technology (KIT) organized a 3-d training course to disseminate knowledge on the application of MC methods for in vivo monitoring. It was intended as a hands-on course centered around an exercise which guided the participants step by step through the calibration process using a simplified version of KIT's equipment. Only introductory lectures on in vivo monitoring and voxel models were given. The course was based on MC codes of the MCNP family, widespread in the community. The strong involvement of the participants and the working atmosphere in the classroom as well as the formal evaluation of the course showed that the approach chosen was appropriate. Participants liked the hands-on approach and the extensive course materials on the exercise. (authors)

    According to the Codex Alimentarius and the European Commission Directive each food has a maximum residual antibiotic (MRLs) however, for honey is still no limit set. Among the main methods that guarantee the detection of antibiotic residues include the Premi Test which is a qualitative method for the detection of antibiotics in honey, but it remains a non-specific method for this matrix and long enough (three hours of incubation). Through this work, we were able to develop and optimize a new kit called Honey test. This kit is able to detect the presence of antibiotic residues in honey by a bacterial strain radio-resistant called D.ra. The duration of treatment is only 30 minutes, requiring incubation at 37 Degree C and treatment with UV at 366 nm. This work will be the subject of a national patent.

    Kanamycin is a broad-spectrum antibiotic and usually used for the treatment of infections when antibiotics like penicillin are less powerful and can not be given. This research was performed to obtain several physicochemical character of 99m Tc-kanamycin which were made in the form of lyophilized kanamycin kit to ensure the later application in humans. Kanamycin diagnostic kit were provided in lyophilized kit comprising kanamycin as ligand compound, pyrophosphate as co-ligand and SnCl 2 as reducing agent. The radiochemical purity was determined by instant thin layer chromatography (ITLC-SG) using 0.5 N NaOH as the mobile phase and ascending paper chromatography using Whatman paper 3 with acetone as the mobile phase. The plasma binding protein of 99m Tc-kanamycin was investigated in vitro by precipitation method using 5% of trichloro acetic acid (TCA) solution, whereas the lipophilicity (log P) was obtained by determination the partition coefficient in organic solvent-water system. Studies on the effect of the amount of radioactivity and the volume of Na 99m TcO 4 solution to the radiochemical purity of 99m Tc-kanamycin were also performed. From this experiment it was obtained that kanamycin lyophilized-kit was hydrophilic, 59.54% of solutions bound to plasma, radiochemical purity was more than 95%, and the final volume of 2 ml dosage was stable up to 2 hours after the addition of 99m Tc with a radioactivity of less then 3 mCi.

    T 3 immunoassay kit was investigated basically and clinically. A good result was obtained at the prescribed incubation temperature and for 16 hours of incubation time. Moreover, it was thought to be possible that incubation time could be shortened to 1 - 4 hours at 37 0 C. Specificity of antibody was good. Recovery of added T 3 was 100+-5 (S.D.) % on an average and parallel of dilution curve of high T 3 serum was also good. Variation coefficient of accuracy of this kit was 1.5 - 2.1 % and that of reproducibility was 1.3 - 6.6 %. Mild hemolysis did not affect measurement value. Serum T 3 level in normals, untreated patients with Basedow's disease and patients with primary hypothyroidism was 142+-21 ng/100 ml, 452+-156 ng/100 ml and 67+-17 ng/100 ml, respectively. Serum T 3 level in patients with Hashimoto's disease was distributed to a wide extent, but that of patients with goiter and simple goiter ranged within normal range. On the other side, serum T 3 level of normal pregnant woman was high and that of patients with anorexia nervosa showed low level. From the above mentioned results, it was concluded that this kit was simple in method and good in sensitivity, specificity and reproducibility and it was also useful for clinical applications. (M.

    KIT (CD117, c-kit) is a receptor tyrosine kinase involved in the tumorigenesis of several neoplasms. KIT is expressed by the secretory cells of normal sweat glands. We studied the KIT expression and KIT mutational status in various benign and malignant tumors of eccrine and apocrine glands. We included a total of 108 cases comprising 10 benign and 6 malignant sweat gland tumors, and KIT expression was immunohistochemically detected (positive rate): 10 syringomas (0%), 8 poromas (25%), 20 mixed tumors (40%), 21 spiradenomas (43%), 1 cylindroma (0%), 5 hidradenomas (40%), 7 syringocystadenoma papilliferum cases (0%), 1 papillary hidradenoma (100%), 2 tubulopapillary hidradenomas (50%), 8 hidrocystomas (29%), 2 adenoid cystic carcinomas (100%), 5 porocarcinomas (20%), 6 apocrine carcinomas (33%), 10 extramammary Paget diseases (30%), 1 spiradenocarcinoma (100%), and 1 syringocystadenocarcinoma papilliferum (0%). Most KIT-positive cells were luminal cells, arising from glandular structures. We performed polymerase chain reaction-single-strand conformation polymorphism for detecting KIT mutational status. All cases showed no mutations at hot spots for KIT (exons 9, 11, 13, and 17). KIT mutation does not seem to be mechanism for KIT expression, but the expression may be from native sweat glands.

    The c-kit protein plays a major role in the regulation of germ cell development. Its expression and distribution in rodent testes have been widely reported. However, research regarding c-kit expression in domestic animals is scarce, and the expression pattern and distribution of c-kit in germ cells have not been clearly defined. In this study, a specific antigenic region for goat c-kit was designed, and a c-kit polyclonal antibody was prepared. This antibody was then applied in a study evaluating c-kit expression in Cashmere goat tissues. A Western blot analysis showed that three forms of c-kit were expressed in goat testes: precursor, mature, and soluble c-kit. Fluorescent immunohistochemical analyses showed that c-kit was primarily expressed in the spermatogonia and spermatocytes of goat testes. These results not only clarify the expression and localization of c-kit in the goat testis, but also accelerate further research regarding the function of c-kit in goat spermatogenesis.

    Pascal B Pfiffner

    Full Text Available A renewed interest by consumer information technology giants in the healthcare domain is focused on transforming smartphones into personal health data storage devices. With the introduction of the open source ResearchKit, Apple provides a framework for researchers to inform and consent research subjects, and to readily collect personal health data and patient reported outcomes (PRO from distributed populations. However, being research backend agnostic, ResearchKit does not provide data transmission facilities, leaving research apps disconnected from the health system. Personal health data and PROs are of the most value when presented in context along with health system data. Our aim was to build a toolchain that allows easy and secure integration of personal health and PRO data into an open source platform widely adopted across 140 academic medical centers. We present C3-PRO: the Consent, Contact, and Community framework for Patient Reported Outcomes. This open source toolchain connects, in a standards-compliant fashion, any ResearchKit app to the widely-used clinical research infrastructure Informatics for Integrating Biology and the Bedside (i2b2. C3-PRO leverages the emerging health data standard Fast Healthcare Interoperability Resources (FHIR.

    similar situations happen also when using other software of the kit. So there are special logical and mathematical tricks to overcome these difficulties.The free accessible software available for the trajectory calculation is either inappropriate for solving the regarded tasks, in principle, or is functionally limited. The real analogues are available either at the rocket and space enterprises, or in research institutes, and a high cost disables their licensing use, especially, in state educational institutions. Besides, such software often falls within the restrictions on double-purpose technology circulation. In spite of the existing non-commercial analogues the developed software kit allows the transformation of the program while dealing with various tasks in new projects. This kit holds an intermediate niche between approximate estimations of vehicle’s ballistic properties at the stage of technical proposal and accurate calculations to be performed, usually, only for final version of the flying vehicle.

When kept at H temperature, HE was low initially, but all kits showed elevated HE at 8 days of age, and the metabolic rate was similar for single kits and kits huddling in groups...... and after the experiments and evaporative water losses (EWL) were calculated. When exposed to L temperature, single kits responded with a very low HE until 29 days of age, and groups of kits until 14 days of age. It was not until they reached an age of approximately 6 weeks that single kits showed a clear....... Evaporative water losses was higher among single than among groups of kits and slightly lower but more variable for animals at L than at H temperature. It was concluded that mink kits develop functional homoeothermy at an age of close to 6 weeks and that the failure of very young kits to thermoregulate...

    In India, the pedagogy of science education is "believe what text book says". Providing schools with appropriate teaching materials to enhance teaching has always been a challenge in a developing country like India. Generally it is not possible for a normal school in India to afford the expensive teaching materials to teach through demonstrations and experiments. Thus students are forced to believe what text book says rather than learning concepts through experiments. The International School of Photonics SPIE (International Society for Optical Engineering) student chapter came up with `Optics kit' to supplement the teaching of optics in school level. `Optics kit', developed with indigenously procured components, could be sold at an affordable prize for an average Indian School. The chapter is currently selling the kit for less than $20. The content of the kit is at par with many kits already available commercially in developed countries, and the price is just 10% compared to those kits. The kit is aimed to higher secondary level students in India, where students are taught Ray optics and basics of Wave Optics. The content of the kit is developed based on this syllabus. The Optics Kit contains simple optical elements like lens, grating, polarizer, mirror, diode laser etc. The kit can be used to demonstrate optics phenomena like interference, diffraction, polarization etc. The kit was developed based on the feedback gathered by the chapter through its outreach activities. The syllabus for the kit was developed through thorough discussion with educational experts in the field of Physics. The student community welcomed the optics kit with overwhelming enthusiasm and hence the project proved to be successful in giving an opportunity for students to "See and Believe" what they are learning.

    The plasticity of c-kit-positive bone marrow cells (c-kit-BMCs) in tissues different from their organ of origin remains unclear. We tested the hypothesis that c-kit-BMCs are functionally heterogeneous and only a subgroup of these cells possesses cardiomyogenic potential. Population-based assays fall short of identifying the properties of individual stem cells, imposing on us the introduction of single cell-based approaches to track the fate of c-kit-BMCs in the injured heart; they included viral gene-tagging, multicolor clonal-marking and transcriptional profiling. Based on these strategies, we report that single mouse c-kit-BMCs expand clonally within the infarcted myocardium and differentiate into specialized cardiac cells. Newly-formed cardiomyocytes, endothelial cells, fibroblasts and c-kit-BMCs showed in their genome common sites of viral integration, providing strong evidence in favor of the plasticity of a subset of BMCs expressing the c-kit receptor. Similarly, individual c-kit-BMCs, which were infected with multicolor reporters and injected in infarcted hearts, formed cardiomyocytes and vascular cells organized in clusters of similarly colored cells. The uniform distribution of fluorescent proteins in groups of specialized cells documented the polyclonal nature of myocardial regeneration. The transcriptional profile of myogenic c-kit-BMCs and whole c-kit-BMCs was defined by RNA sequencing. Genes relevant for engraftment, survival, migration, and differentiation were enriched in myogenic c-kit-BMCs, a cell subtype which could not be assigned to a specific hematopoietic lineage. Collectively, our findings demonstrate that the bone marrow comprises a category of cardiomyogenic, vasculogenic and/or fibrogenic c-kit-positive cells and a category of c-kit-positive cells that retains an undifferentiated state within the damaged heart.

  3. Mutations in Exons 9 and 13 of KIT Gene Are Rare Events in Gastrointestinal Stromal Tumors

    Gastrointestinal stromal tumors (GISTs), the most common mesenchymal tumors of the gastrointestinal tract, typically express the KIT protein. Activating mutations in the juxtamembrane domain (exon 11) of the c-kit gene have been shown in a subset of GISTs. These mutations lead into ligand-independent activation of the tyrosine kinase of c-kit, and have a transforming effect in vitro. Several groups have studied the clinical implication of the c-kit mutation status of exon 11 in GISTs and a possible relationship between c-kit mutations and malignant behavior has been established. Recently, a 1530ins6 mutation in exon 9 and missense mutations, 1945A>G in exon 13 of the c-kit gene were reported. The frequency and clinical importance of these findings are unknown. In this study we evaluated 200 GISTs for the presence of mutations in exons 9 and 13 of c-kit. Six cases revealed 1530ins6 mutation in exon 9 and two cases 1945A>G mutation in exon 13. All tumors with mutations in exon 9 and 13 lacked mutations in exon 11 of c-kit. None of the analyzed tumors had more than one type of c-kit mutation. All but one of the eight tumors with mutations in exon 9 or 13 of the c-kit gene were histologically and clinically malignant. All four of six cases with exon 9 mutation of which location of primary tumor was known, were small intestinal, suggesting that this type of mutation could preferentially occur in small intestinal tumors. Exon 9 and 13 mutations seem to be rare, and they cover only a small portion (8%) of the balance of GISTs that do not have mutations in exon 11 of c-kit. This finding indicates that other genetic alterations may activate c-kit in GISTs, or that KIT is not activated by mutations in all cases. PMID:11021812

    2018-01-01

    In January 2015 the NASA Goddard Space Flight Center (GSFC) released the Core Flight System (cFS) as open source under the NASA Open Source Agreement (NOSA) license. The cFS is based on flight software (FSW) developed for 12 spacecraft spanning nearly two decades of effort and it can provide about a third of the FSW functionality for a low-earth orbiting scientific spacecraft. The cFS is a FSW framework that is portable, configurable, and extendable using a product line deployment model. However, the components are maintained separately so the user must configure, integrate, and deploy them as a cohesive functional system. This can be very challenging especially for organizations such as universities building cubesats that have minimal experience developing FSW. Supporting universities was one of the primary motivators for releasing the cFS under NOSA. This paper describes the OpenSatKit that was developed to address the cFS deployment challenges and to serve as a cFS training platform for new users. It provides a fully functional out-of-the box software system that includes NASA's cFS, Ball Aerospace's command and control system COSMOS, and a NASA dynamic simulator called 42. The kit is freely available since all of the components have been released as open source. The kit runs on a Linux platform, includes 8 cFS applications, several kit-specific applications, and built in demos illustrating how to use key application features. It also includes the software necessary to port the cFS to a Raspberry Pi and instructions for configuring COSMOS to communicate with the target. All of the demos and test scripts can be rerun unchanged with the cFS running on the Raspberry Pi. The cFS uses a 3-tiered layered architecture including a platform abstraction layer, a Core Flight Executive (cFE) middle layer, and an application layer. Similar to smart phones, the cFS application layer is the key architectural feature for users to extend the FSW functionality to meet their

    Most Strategic Environmental Assessment (SEA) research and applications have so far neglected the ex post stages of the process, also called SEA follow-up. Tool kits and methodological frameworks for engaging effectively with SEA follow-up have been conspicuously missing. In particular, little has so far been learned from the much more mature evaluation literature although many aspects are similar. This paper provides an analytical framework and tool kit for SEA follow-up. It is based on insights and tools developed within programme evaluation and environmental systems analysis. It is also grounded in empirical studies into real planning and programming practices at the regional level, but should have relevance for SEA processes at all levels. The purpose of the framework is to promote a learning-oriented and integrated use of SEA follow-up in strategic decision making. It helps to identify appropriate tools and their use in the process, and to systematise the use of available data and knowledge across the planning organization and process. It distinguishes three stages in follow-up: scoping, analysis and learning, identifies the key functions and demonstrates the informational linkages to the strategic decision-making process. The associated tool kit includes specific analytical and deliberative tools. Many of these are applicable also ex ante, but are then used in a predictive mode rather than on the basis of real data. The analytical element of the framework is organized on the basis of programme theory and 'DPSIR' tools. The paper discusses three issues in the application of the framework: understanding the integration of organizations and knowledge; understanding planners' questions and analytical requirements; and understanding interests, incentives and reluctance to evaluate

    Retention of new graduates in nursing continues to be a significant workplace issue, particularly in light of the heightening nursing shortage. Experienced nurses are in a pivotal position to positively impact retention, and, because of this, they can be called "keystoners". Mentoring, an important role of the keystoner, requires specific skills and knowledge and can be learned. A tool kit designed to develop the mentoring skills of keystoners is described. The result of successful mentoring among keystoners can be multifaceted; workplace satisfaction and higher retention of new graduates are targeted outcomes.

    Full Text Available Michael J Cook,1 Basant K Puri2 1Independent researcher, Dorset, UK; 2Department of Medicine, Hammersmith Hospital, Imperial College London, London, UK Abstract: The clinical diagnosis of Lyme borreliosis can be supported by various test methodologies; test kits are available from many manufacturers. Literature searches were carried out to identify studies that reported characteristics of the test kits. Of 50 searched studies, 18 were included where the tests were commercially available and samples were proven to be positive using serology testing, evidence of an erythema migrans rash, and/or culture. Additional requirements were a test specificity of ≥85% and publication in the last 20 years. The weighted mean sensitivity for all tests and for all samples was 59.5%. Individual study means varied from 30.6% to 86.2%. Sensitivity for each test technology varied from 62.4% for Western blot kits, and 62.3% for enzyme-linked immunosorbent assay tests, to 53.9% for synthetic C6 peptide ELISA tests and 53.7% when the two-tier methodology was used. Test sensitivity increased as dissemination of the pathogen affected different organs; however, the absence of data on the time from infection to serological testing and the lack of standard definitions for “early” and “late” disease prevented analysis of test sensitivity versus time of infection. The lack of standardization of the definitions of disease stage and the possibility of retrospective selection bias prevented clear evaluation of test sensitivity by “stage”. The sensitivity for samples classified as acute disease was 35.4%, with a corresponding sensitivity of 64.5% for samples from patients defined as convalescent. Regression analysis demonstrated an improvement of 4% in test sensitivity over the 20-year study period. The studies did not provide data to indicate the sensitivity of tests used in a clinical setting since the effect of recent use of antibiotics or steroids or other

    1999-06-01

    In addition to food, clothing, and shelter, the hundreds of thousands of refugees fleeing Kosovo need primary health care services, including reproductive health care. The United Nations Population Fund (UNFPA) estimates that of a population of 350,000 refugees in Albania, 35,000 are women in need of prenatal or postnatal care. According to UNFPA, 7 babies were born in 1 refugee camp alone in one 24-hour period, and there are widespread reports of the systematic rape of ethnic Albanian women as they flee. In response, UNFPA announced in early April that it is coordinating the delivery of emergency reproductive health kits to Albanian refugee camps. Each kit contains clean delivery supplies, emergency contraceptive pills (ECP) for women who have been raped, counseling information for post-rape trauma, supplies to treat the complications of unsafe abortion, and condoms, IUDs, and other contraceptive methods. UNFPA expects to send enough supplies to care for the refugees for up to 6 months, with most supplies aimed at providing safe deliveries. The Vatican immediately condemned UNFPA's distribution of ECPs. Whether the US will renew its funding of UNFPA is pending before Congress.

    The laboratory performance of a double antibody radioimmunoassay (RIA) kit for measuring osteocalcin (OC) was tested for incubation, the effect of anticoagulants, serum storage, dilution, recovery, and reproducibility. Serum OC concentrations increased rapidly with the addition of 5 mM or more ethylenediamine tetraacetic acid, although they were not affected by the addition of heparin. Serum OC measurements, obtained at 2 or 3 weeks after sampling, tended to be lower. The other items, except for dilution, were reliable. Using the OC RIA kit, serum OC concentrations were measured in 161 patients with various diseases and 408 volunteers. Normal upper limit for OC was defined as 11.48 ng/ml. Serum OC concentrations were extremely high up to the age of puberty, and thereafter decreased rapidly with the constant values after the age of 20. Women had increased OC values after the latter half of their fourties. Primary hyperparathyroidism, bone metastases of malignancy, and malignant hypercalcemia were occasionally associated with increased OC values, in contrast to hypoparathyroidism showing decreased OC values. Extremely high values of OC were seen in many of the dialysis patients. (Namekawa, K.)

    Direct DNA amplification in forensic genotyping reduces analytical time when large sample sets are being analyzed. The amplification success depends mainly upon two factors: on one hand, the PCR chemistry and, on the other, the type of solid substrate where the samples are deposited. We developed a workflow strategy aiming to optimize times and cost when starting from blood samples spotted onto diverse absorbent substrates. A set of 770 blood samples spotted onto Blood cards, Whatman ® 3 MM paper, FTA™ Classic cards, and Whatman ® Grade 1 was analyzed by a unified working strategy including a low-cost pre-treatment, a PCR amplification volume scale-down, and the use of the 3500 Genetic Analyzer as the analytical platform. Samples were analyzed using three different commercial multiplex STR direct amplification kits. The efficiency of the strategy was evidenced by a higher percentage of high-quality profiles obtained (over 94%), a reduced number of re-injections (average 3.2%), and a reduced amplification failure rate (lower than 5%). Average peak height ratio among different commercial kits was 0.91, and the intra-locus balance showed values ranging from 0.92 to 0.94. A comparison with previously reported results was performed demonstrating the efficiency of the proposed modifications. The protocol described herein showed high performance, producing optimal quality profiles, and being both time and cost effective.

    The aim of this project is to develop a Computerized Numerical Controlled (CNC) retrofitting kit for a lathe machine, study its behavior and compare its performance with the retrofitting kit already designed and fabricated at (Pakistan Institute of Engineering and Applied Sciences (PIEAS). Design calculations were performed assuming 100 mm work piece diameter and 800 mm length of stock using tool materials HSS, uncoated carbide, coated carbide, ceramic and cermet tools for different materials. Also cutting, thrust and radial forces on a single point cutting tool were determined. Stepper motors of torque 972 oz-in were selected to drive the carriage and cross-slide in Z and X-directions respectively. Power screws were replaced with ball screws of 0.63 inch dia. (x-direction) and 1.26 in. dia. (Z-direction) which were locally manufactured in the workshop. Deep groove and Angular contact ball bearings were used to support the ball screw shafts against axial and radial loads. Flexible and plain couplings were developed to couple encoders and motors to the ball screw shafts respectively. Panel mount optical rotary encoders are being used for feedback control. Mechanical assembly is complete but due to unavailability of wiring diagram for motors, control electronics could not be accomplished. Therefore, machine could not be evaluated in terms of accuracy, repeatability and resolution using computer software. (author)

    2010-01-01

    The measurement of the experiment software performance is a very important metric in order to choose the most effective resources to be used and to discover the bottlenecks of the code implementation. In this work we present the benchmark techniques used to measure the ATLAS software performance through the ATLAS offline testing engine Kit Validation and the online portal Global Kit Validation. The performance measurements, the data collection, the online analysis and display of the results will be presented. The results of the measurement on different platforms and architectures will be shown, giving a full report on the CPU power and memory consumption of the Monte Carlo generation, simulation, digitization and reconstruction of the most CPU-intensive channels. The impact of the multi-core computing on the ATLAS software performance will also be presented, comparing the behavior of different architectures when increasing the number of concurrent processes. The benchmark techniques described in this paper have been used in the HEPiX group since the beginning of 2008 to help defining the performance metrics for the High Energy Physics applications, based on the real experiment software.

    This paper describes the development of a lyophilized cold kit of DOTA-[Tyr 3 ]-Octreotide (DOTA-TOC) for instant compounding of 68 Ga-DOTA-TOC, suitable for diagnosis of neuroendocrine tumors. The work involved formulation of DOTA-TOC kits, optimization of radiolabeling, quality control of 68 Ga-DOTA-TOC and animal biodistribution studies. The prepared kits enable a reliable method for preparation of 68 Ga-DOTA-TOC of high radiochemical purity and excellent stability. Availability of such kits along with 68 Ge/ 68 Ga generators is expected to stimulate the widespread use of 68 Ga-DOTA-TOC in nuclear medicine practice in developing countries. (author)

    In accordance with alterations of the political and economical settings of Central Europe in the last decades, the characteristics of NBC hazards have changed. Since war appears unlikely, possible new scenarios involve pandemics, chemical transport accidents or distribution of CB warfare agents and radioactive materials by terroristic acts. Meeting this situation requires new protection and self aid equipment for the German civilian disaster relief forces. The German government has reacted to these risks by designing personal protection equipment for the civilian voluntary and professional disaster relief forces. The new NBC self aid kit will be part of this effort. The scientific approach of the project consisted of an updated risk analysis, a questionnaire for the professionals and volunteers involved in disaster management, a thorough evaluation of commercially available kits and single components, final design of the new kit including user instructions, and validation of a prototype kit in a disaster relief exercise. Results of the questionnaire stressed the need for a NBC self aid kit fulfilling the demands of easy handling, use of commercially available components, stability of materials, consumption adapted supply and portable size and weight of the complete kit. The evaluation of international NBC equipment could not identify any current NBC self aid kit which satisfies all needs of the German civilian disaster relief forces. The authors therefore compiled a new kit consisting of commercially available components. The newly developed kit was evaluated in a disaster relief exercise.

    Advances of tissue microarray (TMA) technology have enabled simultaneous in situ analysis of biomarker expression in a large number of archived pathology specimens. However, the relatively high cost of TMA construction may hamper many researchers from using this essential tool of modern pathology research. We discuss methods for making TMA kits and recipient blocks for manual construction of high-density TMAs at low cost. Ordinary cannula piercing needles, hypodermic needles, bone marrow biopsy needles, metallic ink cartridges of ballpoint pens, and disposable skin biopsy punches were used to construct self-made manual TMA kits. The recipient blocks were manufactured by boring holes in the conventional bare paraffin blocks. A mini electric hand drill and a microcompound table assembled on a drill stand were used to maximize the capacity of the recipient blocks. By using TMA kits made from cannula piercing needles (16- and 18-gauge), it was possible to construct TMAs with 1 mm×140 cores, 0.6 mm×320 cores, 2 mm×70 cores, 3 mm×35 cores, and 5 mm×12 cores. The capacity of the recipient blocks could be dramatically increased by drilling holes. Construction of TMAs using self-made TMA kits is an inexpensive alternative to construction of TMAs using commercial devices.

    Over the years, sensor networks technology has evolved tremendously and has great potential in environmental sensing applications. However, because sensor networks are usually designed and built by computer scientists and engineers with little input from the scientific community, the resulting technology is often complex and out of reach for most field scientists. A few sensor, and data logger vendors have released data acquisition systems that can be used with their products. Unfortunately, these are generally vendor-specific, requiring scientists with heterogeneous sensors to use multiple systems to acquire data from all their sensors. A few, more generic systems, are compatible with multiple brands. However, these often offer only limited functionality, little flexibility, and no extensibility. We built SensorKit to overcome these limitations and to accelerate the adoption of sensor networks by field scientists. Using a simplicity-through-sophistication approach, we provide scientists with a powerful tool for field data collection. SensorKit is hardware agnostic, and was built using commercial off-the-shelf components. By employing a Linux-based ultra low-power generic embedded processing platform with a variety of dataloggers (including Berkeley motes, National Instruments' Compact RIOs, as well as legacy and newer PakBus-based Campbell data loggers), we support requirements from a large number of scientists. The user interfaces are designed to be intuitive so that most scientists can deploy, configure, and operate the system without extensive training. Working in close collaboration with field scientists allowed us to better understand scientific requirements and ensure system relevancy. The requirements for data acquisition, data storage, and data communication vary significantly for each deployment. Data acquisition needs to include capabilities for different analog, digital, and other complex sensors (e.g. cameras, and robotic sensors). Moreover, the

    Gastrointestinal stromal tumors (GISTs) are common mesenchymal neoplasms in the gastrointestinal tract of humans and dogs. Little is known about the pathogenesis of these tumors. This study evaluated the role of c-KIT in canine GISTs; specifically, we investigated activating mutations in exons 8, 9, 11, 13, and 17 of c-KIT and exons 12, 14, and 18 of platelet-derived growth factor receptor, alpha polypeptide (PDGFRA), all of which have been implicated in human GISTs. Seventeen canine GISTs all confirmed to be positive for KIT immunostaining were studied. Exons 8, 9, 11, 13 and 17 of c-KIT and exons 12, 14, and 18 of PDGFRA, were amplified from DNA isolated from formalin-fixed paraffin-embedded samples. Of these seventeen cases, six amplicons of exon 11 of c-KIT showed aberrant bands on gel electrophoresis. Sequencing of these amplicons revealed heterozygous in-frame deletions in six cases. The mutations include two different but overlapping six base pair deletions. Exons 8, 9, 13, and 17 of c-KIT and exons 12, 14, and 18 of PDGFRA had no abnormalities detected by electrophoresis and sequencing did not reveal any mutations, other than synonymous single nucleotide polymorphisms (SNPs) found in exon 11 of c-KIT and exons 12 and 14 of PDGFRA. The deletion mutations detected in canine GISTs are similar to those previously found in the juxtamembrane domain of c-KIT in canine cutaneous mast cell tumors in our laboratory as well as to those reported in human GISTs. Interestingly, none of the other c-KIT or PDGFRA exons showed any abnormalities in our cases. This finding underlines the critical importance of c-KIT in the pathophysiology of canine GISTs. The expression of KIT and the identification of these activating mutations in c-KIT implicate KIT in the pathogenesis of these tumors. Our results indicate that mutations in c-KIT may be of prognostic significance and that targeting KIT may be a rational approach to treatment of these malignant tumors. This study further

    Advanced systemic mastocytosis (SM) is characterized by uncontrolled growth of neoplastic mast cells (MC) and drug resistance. The tyrosine kinase receptor KIT is often mutated and activated and thus contributes to malignant growth of MC. Therefore, KIT-targeting drugs are currently tested for their ability to block growth of malignant MC. We determined the effects of the multikinase inhibitor INNO-406 (bafetinib) on primary neoplastic MC, the canine mastocytoma cell line C2, the human MC leukemia cell line HMC-1.1 bearing the KIT mutant V560G, and HMC-1.2 cells harboring KIT V560G and KIT D816V. INNO-406 was found to inhibit proliferation in HMC-1.1 cells (IC(50): 30-40 nM), but not in HMC-1.2 cells or primary neoplastic cells in patients with KIT D816V-positive SM. In canines, growth-inhibitory effects of INNO-406 were seen in C2 cells (IC(50): 50-100 nM) exhibiting a KIT exon 11 internal tandem-duplication and in primary neoplastic MC harboring wild-type exon 11, whereas no effects were seen in MC exhibiting a polymorphism at amino acid 581 in exon 11. INNO-406 was found to block KIT phosphorylation and expression in HMC-1.1 cells and C2 cells, but not in HMC-1.2 cells, whereas Lyn-phosphorylation was blocked by INNO-406 in all types of MC. In neoplastic MC, the major target of INNO-406 appears to be KIT. Drug responses may depend on the presence and type of KIT mutation. In human MC, the KIT D816V mutant introduces resistance, and in canine mastocytomas, an exon 11 polymorphism may be indicative of resistance against INNO-406.

    2017-12-01

    This paper introduces a Software Development Kit (SDK) that enables the creation of custom software applications that automate the control of a cryo-refrigerator (Quantum Design model GA-1) in third party instruments. A remote interface allows real time tracking and logging of critical system diagnostics such as pressures, temperatures, valve states and run modes. The helium compressor scroll capsule speed and Gifford-McMahon (G-M) cold head speed can be manually adjusted over a serial communication line via a CAN interface. This configuration optimizes cooling power, while reducing wear on moving components thus extending service life. Additionally, a proportional speed control mode allows for automated throttling of speeds based on temperature or pressure feedback from a 3rd party device. Warm up and cool down modes allow 1st and 2nd stage temperatures to be adjusted without the use of external heaters.

    The study focuses on the use of an orbital maneuvering system (OMS) payload bay kit (PBK) designed to utilize OMS tanks identical to those currently employed in the Orbiter OMS pods. Emphasis is placed on payload deployment capability and payload servicing/reboost capability augmentation from the point of view of payload mass, maximum deployment altitudes, and initial retrieval and final deployment altitudes. The deployment, servicing, and reboost requirements of the Hubble Space Telescope and Advanced X-ray and Astrophysics Facility are analyzed in order to show the benefits an OMS PBK can provide for these missions. It is shown that OMS PBKs can provide the required capability enhancement necessary to support deployment, reboost, and servicing of payloads requiring altitudes greater than 325 nautical miles.

    Full Text Available This article provides something of a survival kit for prospective phenomenologists. Starting with the main ideas of the founder of phenomenology Edmund HUSSERL, this article begins by articulating phenomenological thinking in abstract painting, existentialism, theology, and psychotherapy. On this background I discuss the theoretical and methodological development of phenomenology in the social sciences. Linking phenomenology and ordinary language philosophy rounds out this hopefully "easy-to-understand" introduction. After having read the text students should be familiar with the philosophical roots, the major application contexts, and some central reservations against phenomenology. Above all, students should be able to (a apply the term "phenomenology" appropriately (at least as far as this is possible and (b meet the requirements of phenomenologically oriented research methods in a reflective and mature way.

    The Directigen Group A Strep test kit (Hynson, Wescott, and Dunning, Baltimore, Md.) was tested for its ability to detect group A streptococci directly from 147 throat swabs. The results were compared with results from conventional culture and Lancefield serological grouping tests. The data showed that 121 of 124 culture-negative throat specimens were also Directigen negative (98%) and that 21 of 23 culture-positive specimens were Directigen positive (91%). If specimens that provided less than 10 colonies per plate of beta-hemolytic streptococci were eliminated, all of the culture-positive specimens were Directigen positive. Positive or negative results were available within 65 to 70 min of testing. The Directigen method is relatively simple to perform and easy to interpret and provides accurate assessment of the presence or absence of group A streptococci in throat swabs, with little or no cross-reactivity with other beta-hemolytic groups.

    The clinical impact of KIT mutations in core binding factor acute myeloid leukemia (CBF-AML) is still unclear. In the present study, we analyzed the prognostic significance of each KIT mutation (D816, N822K, and other mutations) in Japanese patients with CBF-AML. We retrospectively analyzed 136 cases of CBF-AML that had gone into complete remission (CR). KIT mutations were found in 61 (45%) of the patients with CBF-AML. D816, N822K, D816 and N822K, and other mutations of the KIT gene were detected in 29 cases (21%), 20 cases (15%), 7 cases (5%), and 5 cases (4%), respectively. The rate of relapse-free survival (RFS) and overall survival (OS) in patients with D816 and with both D816 and N822K mutations was significantly lower than in patients with other or with no KIT mutations (RFS: p mutation was associated with a significantly worse prognosis. In a further multivariate analysis of RFS and OS, D816 mutation was found to be an independent risk factor for significantly poorer prognosis. In the present study, we were able to establish that, of all KIT mutations, D816 mutation alone is an unfavorable prognostic factor.

    IMPORTANCE The KIT receptor is mutated in approximately 15%of acral, mucosal, and chronic, sun-damaged melanomas. The status of KIT mutations is of interest because they usually are mutually exclusive with N-RAS and B-RAF mutations and because of the availability of KIT kinase inhibitors in the clinic. Some recurrent KIT mutations are well characterized; others are poorly described.OBSERVATIONS We describe a novel KIT mutation in a patient with metastatic melanoma. The mutation, located in exon 13, resulted in S628N substitution in the KIT receptor. Using all-atom molecular dynamics simulations, biochemical assays, and cell-based assays, we showed that the mutation is a bona fide gain-of-function oncogenic mutation. Furthermore,we evaluated the sensitivity of the mutant to imatinib and dasatinib.CONCLUSIONS AND RELEVANCE We report a novel KIT gain-of-function mutation with S628N substitution (exon 13) and show that it is sensitive to imatinib in vitro. Therefore, patients with this mutation may be eligible for KIT kinase inhibitor–based therapy. Further studies are needed to evaluate the clinical benefit of such therapy.

    Melanoma can be stratified into unique subtypes based on distinct pathologies. The acral/mucosal melanoma subtype is characterized by aberrant and constitutive activation of the proto-oncogene receptor tyrosine kinase C-KIT, which drives tumorigenesis. Treatment of these melanoma patients with C-KIT inhibitors has proven challenging, prompting us to investigate the downstream effectors of the C-KIT receptor. We determined that C-KIT stimulates MAP kinase-interacting serine/threonine kinases 1 and 2 (MNK1/2), which phosphorylate eukaryotic translation initiation factor 4E (eIF4E) and render it oncogenic. Depletion of MNK1/2 in melanoma cells with oncogenic C-KIT inhibited cell migration and mRNA translation of the transcriptional repressor SNAI1 and the cell cycle gene CCNE1. This suggested that blocking MNK1/2 activity may inhibit tumor progression, at least in part, by blocking translation initiation of mRNAs encoding cell migration proteins. Moreover, we developed an MNK1/2 inhibitor (SEL201), and found that SEL201-treated KIT-mutant melanoma cells had lower oncogenicity and reduced metastatic ability. Clinically, tumors from melanoma patients harboring KIT mutations displayed a marked increase in MNK1 and phospho-eIF4E. Thus, our studies indicate that blocking MNK1/2 exerts potent antimelanoma effects and support blocking MNK1/2 as a potential strategy to treat patients positive for KIT mutations.

    1983-01-01

    Plasma C-peptide immunoreactivity (CPR) was measured in 18 fasting subjects with three different commercial kits (RIA-mat C-peptide-, Byk-Mallinckrodt; RIA-gnost-hC-peptide, Hoechst-Behring; human C-peptide radioimmunoassay kit, Novo) The subjects were chosen as to cover a wide range of CPR concentrations (five healthy subjects, six obese subjects, three insulin-dependent diabetics, four normal subjects whose plasmas had been kept at - 20 0 C for periods of 16 or 36 months). CPR was measured with the Novo kit in eight other plasmas which were kept over a period of 36 months, with or without aprotinin. Good correlations have been established among the values found with the three kits. However, absolute concentration values for each subject as well as the dispersion of all plasma C-peptide values varied as a function of the kit used because of antibody specificity differences and because of the various separation methods. The normal range proposed changes with each kit and the blood CPR of a subject can be a normal, reduced or increased one, depending on the kit used. After several months of storage, plasma CPR degradation is observed with the three kits. A protease-inhibitor is necessary in order to avoid this C-peptide degradation due to the apparent existence of a plasma proteolytic enzyme

    Peigné, M; Robin, G; Catteau-Jonard, S; Giacobini, P; Dewailly, D; Pigny, P

    2017-10-01

    Serum AMH measurement became a key element in clinical practice, especially before using Assisted reproductive techniques (ART). However, many AMH kits exist giving different AMH results, leading to a confusion in their interpretation. Until recently, only manual ELISA kits existed (mainly Gen II Beckman, EIA/AMH Immunotech and two Anshlab kits) reporting non-interchangeable results. High and low AMH cut-off values, mainly useful to adapt therapeutics in ART, were different between kits. Since the end of 2014, the arrival of two automatic assays (Access Dxi Beckman and AMH Elecsys Roche) seems to improve the sensitivity and the reproducibility of AMH measurement. It could simplify the interpretation of AMH values and improve our clinical choices.

    Hepatitis B antigen and antibody were determined simultaneously by radioimmunoassay using the Biotest combRIA-Au kit. The results in determining antigens and antibodies in sera with a known content of these substances by this kit nearly equal those of isolated determinations of antigen by the Abbott AUSRIA II-125 kit, and of antibody by the Abbott AUSAB kit, resp., except for a negligible number of sera with a very low content of either antigen or antibody.

    Ophiocordyceps sinensis is a valuable traditional Chinese medicine. Due to resource shortage, expensive price and huge market demand, there are many adulterants of O. sinensis in markets. Therefore, it is necessary to establish a rapid and effective method for distinguishing O. sinensis. Based on the species-specific PCR of O. sinensis, this study developed a detection kit by optimizing the components and evaluated the specificity, detection limit, repeatability and shelf life of the kit. The results showed that when the quality of O. sinensis accounted for more than 1/200 of that mixture, it could be detected successfully. Moreover, only O. sinensis could be amplified and glowed bright green fluorescence under ultraviolet light. The kit was still in effect when it was placed at 37 ℃ for three days, which indicated that it was stable and effective for one year stored in 4 ℃. The kit in the same batch under different operation conditions, and in different batch under the same operation conditions gave the same result and accuracy, which showed good repeatability of the kit. It is simple, rapid and accurate to distinguish O. sinensis from its adulterants using the kit, and lays the foundation for commercialization of traditional Chinese medicine fast detection kit.

    We developed an immunochromatographic assay kit that uses fluorescent silica nanoparticles bound to anti-Acanthamoeba antibodies (fluorescent immunochromatographic assay [FICGA]) and evaluated its efficacy for the detection of Acanthamoeba and diagnosis of Acanthamoeba keratitis (AK). The sensitivity of the FICGA kit was evaluated using samples of Acanthamoeba trophozoites and cysts diluted to various concentrations. A conventional immunochromatographic assay kit with latex labels (LICGA) was also evaluated to determine its sensitivity in detecting Acanthamoeba trophozoites. To check for cross-reactivity, the FICGA was performed by using samples of other common causative pathogens of infectious keratitis, such as Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, and Candida albicans. Corneal scrapings from patients with suspected AK were tested with the FICGA kit to detect the presence of Acanthamoeba, and the results were compared with those of real-time PCR. The FICGA kit detected organisms at concentrations as low as 5 trophozoites or 40 cysts per sample. There were no cross-reactivities with other pathogens. The FICGA was approximately 20 times more sensitive than the LICGA for the detection of Acanthamoeba trophozoites. The FICGA kit yielded positive results for all 10 patients, which corresponded well with the real-time PCR results. The FICGA kit demonstrated high sensitivity for the detection of Acanthamoeba and may be useful for the diagnosis of AK. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    To compare the effects of two ELISA kits on IgG antibody detection of human Echinococcus granulosus. A Total of 134 sera of patients with echinococcosis, paragonimiasis westermani, clonorchiasis sinensis, schistosomiasis japonica, and cysticercosis cellulosae, and normal persons were detected by two IgG ELISA kits produced by different companies. Furthermore, the specificity, sensitivity and cross reactivity were counted and analyzed statistically. The sensitivity and specificity were extremely high of the two kits as 100.00%. The cross-reactivity rates were 25.00% (paragonimiasis westermani), 26.09% (clonorchiasis sinensis), 10.00% (schistosomiasis japonica), and 87.5% (cysticercosis), respectively, by using the kit produced by the Combined Company in Shenzhen; the cross-reactivity rates were 5.00% (paragonimiasis westermani), 13.04% (clonorchiasis sinensis), 20.00% (schistosomiasis japonica), and 93.75% (cysticercosis) respectively, by using the kit produced by Haitai Company in Zhuhai. In addition, there was a significant difference of Paragonimus westermani detection (P 0.05) between the two kits. Both ELISA kits on IgG antibody detection of human Echinococcus granulosus have the advantages of a high sensitivity, specificity, convenience and high-speed. However, it is also in urgent need to further solve the cross-reactivity of Echinococcus granulosus with other parasites, in order to improve the accuracy of early diagnosis.

  14. Analyzing Approaches to the Backlog of Untested Sexual Assault Kits in the U.S.A.

    2018-03-05

    Motivated by the debate over how to deal with the huge backlog of untested sexual assault kits in the U.S.A., we construct and analyze a mathematical model that predicts the expected number of hits (i.e., a new DNA profile matches a DNA sample in the criminal database) as a function of both the proportion of the backlog that is tested and whether the victim-offender relationship is used to prioritize the kits that are tested. Refining the results in Ref. (Criminol Public Policy, 2016, 15, 555), we use data from Detroit, where government funding was used to process ≈15% of their backlog, to predict that prioritizing stranger kits over nonstranger kits leads to only a small improvement in performance (a 0.034 increase in the normalized area under the curve of the hits vs. proportion of backlog tested curve). Two rough but conservative cost-benefit analyses-one for testing the entire backlog and a marginal one for testing kits from nonstranger assaults-suggest that testing all sexual assault kits in the backlog is quite cost-effective: for example, spending ≈$1641 to test a kit averts sexual assaults costing ≈$133,484 on average. © 2018 The Authors.

    The effectiveness of a direct quantification assay is essential to the adoption of the combined direct quantification/direct STR workflow. In this paper, the feasibility of using the Quantifiler(®) Trio DNA quantification kit for the direct quantification of forensic casework samples was investigated. Both low-level touch DNA samples and blood samples were collected on PE swabs and quantified directly. The increased sensitivity of the Quantifiler(®) Trio kit enabled the detection of less than 10pg of DNA in unprocessed touch samples and also minimizes the stochastic effect experienced by different targets in the same sample. The DNA quantity information obtained from a direct quantification assay using the Quantifiler(®) Trio kit can also be used to accurately estimate the optimal input DNA quantity for a direct STR amplification reaction. The correlation between the direct quantification results (Quantifiler(®) Trio kit) and the direct STR results (GlobalFiler™ PCR amplification kit(*)) for low-level touch DNA samples indicates that direct quantification using the Quantifiler(®) Trio DNA quantification kit is more reliable than the Quantifiler(®) Duo DNA quantification kit for predicting the STR results of unprocessed touch DNA samples containing less than 10pg of DNA.

    Castro, M.; Cruz, J.; Sanchez, M.

    2009-01-01

    Kits of 99 m Tc radiopharmaceuticals are used in nuclear medicine for diagnosis of different diseases. Sn (II) is one of the essential components in their formulations, which is used for reduction 99 m Tc-pertechnetate in cold kits for on-site preparation 99 m Tc-pertechnetate radiopharmaceuticals. Usually, these cold kits contain different additives (complexing agents, antioxidants, buffers, etc.) and the amount of Sn (II) varies from kit to kit. The determination of Sn in these products is essential in assessing their quality. We report here the development of a new polarographic method for the determination of Sn (II) and total Sn in representative radiopharmaceuticals kits (for the content of Sn and chemical composition) produced at the Center of Isotopes of Cuba (CENTIS). These methods were validated by analysis of variance and recovery techniques. From the results of the validation, the characteristic functions of uncertainties and fits are considered for the established methods, which give the necessary evidences to demonstrate the usefulness of these methods according to the current trends in Analytical Chemistry. This work provides practical results of great importance for CENTIS. After the speciation of Sn in the MAG3 radiopharmaceuticals kit is inferred that the production process is affected by uncontrolled factors that influence in the product stability, which demonstrates the necessity for analytical tools for the characterization of products and processes.

    The monitoring of infliximab drug levels aids in the management of several autoimmune diseases, notably inflammatory bowel disease. Several commercial kits are now available and approved by the Therapeutic Goods Administration (TGA) for the measurement of infliximab levels, but there have been limited verification or comparison studies to date. Finding an assay that most accurately measures infliximab is essential for optimal drug titration and patient management. We performed this study to compare the performance of the Grifols Promonitor, Theradiag Lisatracker and R-Biopharm Ridascreen enzyme linked immunosorbent assay (ELISA) kits. Preparations of serum containing known concentrations of infliximab were assayed using each kit, including in the presence of interference from anti-infliximab antibodies, autoantibodies and other biological agents. The Lisatracker kit provided the most accurate determination of infliximab drug levels, however it yielded false positive results at low concentrations of infliximab. The average coefficients of variation (CVs) for the kits were 8% for Lisatracker, 5% for Ridascreen and 11% for Grifols. Infliximab measurements across all kits were affected by interference from antibodies to infliximab (ATI). This study identified the Lisatracker kit as the most accurate in quantifying infliximab levels, although it was limited by false positive results at low concentrations of infliximab as well as interference from ATI. This has important implications for the monitoring and management of patients receiving infliximab therapy. Crown Copyright © 2016. Published by Elsevier B.V. All rights reserved.

  19. Epigenetic regulation of cardiac progenitor cells marker c-kit by stromal cell derived factor-1α.

    Directory of Open Access Journals (Sweden)

    Zhongpu Chen

    Full Text Available BACKGROUND: Cardiac progenitor cells (CPCs have been proven suitable for stem cell therapy after myocardial infarction, especially c-kit(+CPCs. CPCs marker c-kit and its ligand, the stem cell factor (SCF, are linked as c-kit/SCF axis, which is associated with the functions of proliferation and differentiation. In our previous study, we found that stromal cell-derived factor-1α (SDF-1α could enhance the expression of c-kit. However, the mechanism is unknown. METHODS AND RESULTS: CPCs were isolated from adult mouse hearts, c-kit(+ and c-kit(- CPCs were separated by magnetic beads. The cells were cultured with SDF-1α and CXCR4-selective antagonist AMD3100, and c-kit expression was measured by qPCR and Western blotting. Results showed that SDF-1α could enhance c-kit expression of c-kit(+CPCs, made c-kit(-CPCs expressing c-kit, and AMD3100 could inhibit the function of SDF-1α. After the intervention of SDF-1α and AMD3100, proliferation and migration of CPCs were measured by CCK-8 and transwell assay. Results showed that SDF-1α could enhance the proliferation and migration of both c-kit(+ and c-kit(- CPCs, and AMD3100 could inhibit these functions. DNA methyltransferase (DNMT mRNA were measured by qPCR, DNMT activity was measured using the DNMT activity assay kit, and DNA methylation was analyzed using Sequenom's MassARRAY platform, after the CPCs were cultured with SDF-1α. The results showed that SDF-1α stimulation inhibited the expression of DNMT1 and DNMT3β, which are critical for the maintenance of regional DNA methylation. Global DNMT activity was also inhibited by SDF-1α. Lastly, SDF-1α treatment led to significant demethylation in both c-kit(+ and c-kit(- CPCs. CONCLUSIONS: SDF-1α combined with CXCR4 could up-regulate c-kit expression of c-kit(+CPCs and make c-kit(-CPCs expressing c-kit, which result in the CPCs proliferation and migration ability improvement, through the inhibition of DNMT1 and DNMT3β expression and global DNMT

    The presence of c-kit positive neurons in sensory ganglia has been verified in various species but not in humans. Our aim has been to identify whether human primary trigeminal neurons label with c-kit/CD117 and thus, whether data gathered in animal studies can be extrapolated to humans. We also intended to establish whether, and which non-neuronal cells also label with c-kit in the trigeminal ganglion. Human adult trigeminal ganglia from eight cadavers were processed for immunohistochemistry on paraffin embedded samples using monoclonal antibodies for CD117/c-kit, and three additional trigeminal ganglia were used for transmission electron microscopy (TEM). To evaluate which neuronal type (A or B) was labeled with c-kit, we evaluated the same neurons on adjacent sections labeled with antibodies for neurofilaments (NF). c-kit has labeled trigeminal neurons (TNs), mast cells and interstitial cells (ICs) within the trigeminal ganglion. c-kit+TNs were NF-and thus were strongly presumed to be nociceptive, as such neurons are known to be NF-poor. c-kit+ICs with long and moniliform processes intermingled with the satellite glial cells (SGCs) of the neuronal envelopes. TEM evaluations confirmed this mixed composition of the neuronal envelopes and demonstrated that the perineuronal ICs are in fact interstitial Cajal-like cells (ICLCs) and/or telocytes. c-kit+TNs were objectified in humans and strongly presumed to be nociceptive. TNs envelopes mostly consist of SGCs, but are also combined with ICLCs/telocytes. Copyright © 2011 Elsevier GmbH. All rights reserved.

    Full Text Available Abstract Background High abundance protein depletion is a major challenge in the study of serum/plasma proteomics. Prior to this study, most commercially available kits for depletion of highly abundant proteins had only been tested and evaluated in adult serum/plasma, while the depletion efficiency on umbilical cord serum/plasma had not been clarified. Structural differences between some adult and fetal proteins (such as albumin make it likely that depletion approaches for adult and umbilical cord serum/plasma will be variable. Therefore, the primary purposes of the present study are to investigate the efficiencies of several commonly-used commercial kits during high abundance protein depletion from umbilical cord serum and to determine which kit yields the most effective and reproducible results for further proteomics research on umbilical cord serum. Results The immunoaffinity based kits (PROTIA-Sigma and 5185-Agilent displayed higher depletion efficiency than the immobilized dye based kit (PROTBA-Sigma in umbilical cord serum samples. Both the PROTIA-Sigma and 5185-Agilent kit maintained high depletion efficiency when used three consecutive times. Depletion by the PROTIA-Sigma Kit improved 2DE gel quality by reducing smeared bands produced by the presence of high abundance proteins and increasing the intensity of other protein spots. During image analysis using the identical detection parameters, 411 ± 18 spots were detected in crude serum gels, while 757 ± 43 spots were detected in depleted serum gels. Eight spots unique to depleted serum gels were identified by MALDI- TOF/TOF MS, seven of which were low abundance proteins. Conclusions The immunoaffinity based kits exceeded the immobilized dye based kit in high abundance protein depletion of umbilical cord serum samples and dramatically improved 2DE gel quality for detection of trace biomarkers.

  2. A New Method to Stabilize c-kit Expression in Reparative Cardiac Mesenchymal Cells

    2016-08-01

    Full Text Available Cell therapy improves cardiac function. Few cells have been investigated more extensively or consistently shown to be more effective than c-kit sorted cells; however, c-kit expression is easily lost during passage. Here, our primary goal was to develop an improved method to isolate c-kitpos cells and maintain c-kit expression after passaging. Cardiac mesenchymal cells (CMCs from wild-type mice were selected by polystyrene adherence properties. CMCs adhering within the first hours are referred to as rapidly adherent (RA; CMCs adhering subsequently are dubbed slowly adherent (SA. Both RA and SA CMCs were c-kit sorted. SA CMCs maintained significantly higher c-kit expression than RA cells; SA CMCs also had higher expression endothelial markers. We subsequently tested the relative efficacy of SA versus RA CMCs in the setting of post-infarct adoptive transfer. Two days after coronary occlusion, vehicle, RA CMCs, or SA CMCs were delivered percutaneously with echocardiographic guidance. SA CMCs, but not RA CMCs, significantly improved cardiac function compared to vehicle treatment. Although the mechanism remains to be elucidated, the more pronounced endothelial phenotype of the SA CMCs coupled with the finding of increased vascular density suggest a potential pro-vasculogenic action. This new method of isolating CMCs better preserves c-kit expression during passage. SA CMCs, but not RA CMCs, were effective in reducing cardiac dysfunction. Although c-kit expression was maintained, it is unclear whether maintenance of c-kit expression per se was responsible for improved function, or whether the differential adherence property itself confers a reparative phenotype independently of c-kit.

    Highlights: • SCF receptor c-Kit is functionally expressed in primary and transformed osteoblasts. • SCF protects primary and transformed osteoblasts from H{sub 2}O{sub 2}. • SCF activation of c-Kit in osteoblasts, required for its cyto-protective effects. • c-Kit mediates SCF-induced Akt activation in cultured osteoblasts. • Akt activation is required for SCF-regulated cyto-protective effects in osteoblasts. - Abstract: Osteoblasts regulate bone formation and remodeling, and are main target cells of oxidative stress in the progression of osteonecrosis. The stem cell factor (SCF)-c-Kit pathway plays important roles in the proliferation, differentiation and survival in a range of cell types, but little is known about its functions in osteoblasts. In this study, we found that c-Kit is functionally expressed in both osteoblastic-like MC3T3-E1 cells and primary murine osteoblasts. Its ligand SCF exerted significant cyto-protective effects against hydrogen peroxide (H{sub 2}O{sub 2}). SCF activated its receptor c-Kit in osteoblasts, which was required for its cyto-protective effects against H{sub 2}O{sub 2}. Pharmacological inhibition (by Imatinib and Dasatinib) or shRNA-mediated knockdown of c-Kit thus inhibited SCF-mediated osteoblast protection. Further investigations showed that protection by SCF against H{sub 2}O{sub 2} was mediated via activation of c-Kit-dependent Akt pathway. Inhibition of Akt activation, through pharmacological or genetic means, suppressed SCF-mediated anti-H{sub 2}O{sub 2} activity in osteoblasts. In summary, we have identified a new SCF-c-Kit-Akt physiologic pathway that protects osteoblasts from H{sub 2}O{sub 2}-induced damages, and might minimize the risk of osteonecrosis caused by oxidative stress.

  5. Efficient ring perception for the Chemistry Development Kit.

    May, John W; Steinbeck, Christoph

    2014-01-30

    The Chemistry Development Kit (CDK) is an open source Java library for manipulating and processing chemical information. A key aspect in handling chemical structures is the determination of the chemical rings. The rings of a structure are used areas including descriptors, stereochemistry, similarity, screening and atom typing. The CDK includes multiple algorithms for determining the rings of a structure on demand. Non-unique descriptions of rings were often used due to the slower performance of the unique alternatives. Efficient algorithms for handling chemical ring perception have been implemented and optimised in the CDK. The algorithms provide much faster computation of new and existing types of rings. Several optimisation and implementation considerations are discussed which improve real case usage. The performance is measured on several publicly available data sets and in several cases the new implementations were found to be more than an order of magnitude faster. Algorithmic improvements allow handling of much larger datasets in reasonable time. Faster computation allows more appropriate rings to be utilised in procedures such as aromaticity. Several areas that require ring perception have also seen a noticeable improvement. The time taken to compute the unique rings is now comparable allowing a correct usage throughout the toolkit. All source code is open source and freely available.

    Full Text Available High-impact storm events have demonstrated the vulnerability of coastal zones in Europe and beyond. These impacts are likely to increase due to predicted climate change and ongoing coastal development. In order to reduce impacts, disaster risk reduction (DRR measures need to be taken, which prevent or mitigate the effects of storm events. To drive the DRR agenda, the UNISDR formulated the Sendai Framework for Action, and the EU has issued the Floods Directive. However, neither is specific about the methods to be used to develop actionable DRR measures in the coastal zone. Therefore, there is a need to develop methods, tools and approaches which make it possible to: identify and prioritize the coastal zones which are most at risk through a Coastal Risk Assessment Framework, and to evaluate the effectiveness of DRR options for these coastal areas, using an Early Warning/Decision Support System, which can be used both in the planning and event-phase. This paper gives an overview of the products and results obtained in the FP7-funded project RISC-KIT, which aims to develop and apply a set of tools with which highly-vulnerable coastal areas (so-called “hotspots” can be identified.

    Full Text Available In 1992, Wornell and Oppenheim did research on a modulation which is formed by using wavelet theory. In some other studies, proved that this modulation can survive on a few channels and has reliability in some applications. Because of this modulation using the concept of fractal, then it is called as fractalmodulation. Fractal modulation is formed by inserting information signal into fractal signals that are selffractal similary. This modulation technique has the potential to replace the OFDM (Orthogonal Frequency Division Multiplexing, which is currently used on some of the latest telecommunication technologies. The purpose of this research is to implement the fractal communication system using Digital Signal Processing Starter Kit (DSK TMS320C6713 without using AWGN and Rayleigh channel in order to obtain the ideal performance of the system. From the simulation results using MATLAB7.4. it appears that this communication system has good performance on some channels than any other communication systems. While in terms of implementation by using (DSK via TMS320C6713 Code Composer Studio (CCS, it can be concluded that thefractal communication system has a better execution time on some tests.

    Full Text Available This study introduces a new framework for developing spatial education programs based on a geometric language and manipulation of ensembles of polyhedra, called X-Colony Knowledge Discovery Kit (KDK. The KDK main goals are to develop spatial intelligence, creativity, strategic planning, forecasting skills, abstract reasoning, self-confidence, and social skills. Landmark studies document that spatial education plays a central role in driving performance in science, technology, engineering and mathematics (STEM occupations, yet spatial education is under-studied and the infrastructure for research on spatial learning is at the beginning. KDK introduces a novel geometric language that allows visual communication and develops spatial abilities by engaging students to perform creative paper folding and various mental spatial transformations. KDK is organized in program sessions consisting of cooperative open-end paper construction activities that engage students to build modular constructions of gradual complexity and to explore various strategies for combining the constructs into novel configurations. KDK supports the Core Math Standard and Science curricula and provides students the opportunity to discover connections between mathematics, science and various other disciplines. A pilot case-control study conducted with fifth grade students indicates an average increase of 17% in geometric reasoning after 8 hours of KDK activities.

    Full Text Available Telemedicine is always a popular topic thanks to the constants advancements of technology. The focus on development of new devices has been mainly on decreasing size to increase portability. Our research focused on improving functionality but not giving up on portability and cost. In this paper we are presenting the first prototype device that measures 4-leads electrocardiogram (ECG and phonocardiogram (PCG signals with low cost, high portability and wireless connectivity features in mind. We designed and developed a prototype that measures ECG using a standard ECG cable; we designed and developed a digital stethoscope prototype and also the necessary hardware for both medical signals to be transmitted through Bluetooth to a computer. We present here the hardware design, a new communication protocol for transmission of both signals from the device to the computer, and the software system to enable remote consultations. We designed the prototype with the main purpose of using low cost parts without sacrificing functionality, with the purpose of using it in remote zones of the Caribbean coast of Colombia. We show open issues and prepare a field implementation of the kit in the target zone.

    A further 3 digoxin radioimmunoassay (RIA) kits have been evaluated for performance and cross-reaction with digitoxin, spironolactone, canrenone and furosemide (Lasix-Hoechst). Effects of serum protein concentrations have also been tested. The kits tested were from the following manufacturers: A) Diagnostic Products Corporation Digoxin RIA Kit. B) Byk-Mallinckrodt SPAC Digoxin Kit. C) Boehringer-Mannheim Digoxin RIA Kit. All kits used a 125 I-labelled tracer. Kit A used a conventional liquid phase system using double-antibody separation for bound and free drug. Kits B and C used a solid-phase antibody coated tube method. All kits showed a lower cross-reaction to digitoxin than quoted by the manufacturer. Cross-reaction to spironolactone (Aldactone - Boehringer-Mannheim) was less than 1.50 nmol/l at a serum concentration of 125 mg/l Aldactone in all 3 kits. The cross-reaction to canrenone was somewhat higher, 5.2 nmol/l 'digoxin' being measured in one kit at a serum canrenone concentration of 125 mg/l. There was no cross-reaction with furosemide in any kit, even at a serum concentration of 5 g/l. The coated-tube assays were affected by serum albumin and globulin concentration changes, one kit showing a difference of over 50% binding in the range 1-20% albumin. The double-antibody kit did not show dependence on the concentration of these proteins. All kits measured digoxin with good reproducibility in the range 0.40-10.0 nmol/l. (orig.) [de

    We investigated the effects of nest box climate on early mink kit mortality and growth. We hypothesised that litters in warm nest boxes experience less hypothermia-induced mortality and higher growth rates during the 1st week of life. This study included data from 749, 1-year-old breeding dams with access to nesting materials. Kits were weighed on days 1 and 7, dead kits were collected daily from birth until day 7 after birth, and nest climate was measured continuously from days 1 to 6. We tested the influences of the following daily temperature (T) and humidity (H) parameters on the number of live-born kit deaths and kit growth: T mean, T min, T max, T var (fluctuation) and H mean. The nest microclimate experienced by the kits was buffered against the ambient climate, with higher temperatures and reduced climate fluctuation. Most (77.0%) live-born kit deaths in the 1st week occurred on days 0 and 1. Seven of 15 climate parameters on days 1 to 3 had significant effects on live-born kit mortality. However, conflicting effects among days, marginal effects and late effects indicated that climate was not the primary cause of kit mortality. Five of 30 climate parameters had significant effects on kit growth. Few and conflicting effects indicated that the climate effect on growth was negligible. One exception was that large nest temperature fluctuations on day 1 were associated with reduced deaths of live-born kit (P<0.001) and increased kit growth (P=0.003). Litter size affected kit vitality; larger total litter size at birth was associated with greater risks of kit death (P<0.001) and reduced growth (P<0.001). The number of living kits in litters had the opposite effect, as kits in large liveborn litters had a reduced risk of death (P<0.001) and those with large mean litter size on days 1 to 7 had increased growth (P=0.026). Nest box temperature had little effect on early kit survival and growth, which could be due to dams' additional maternal behaviour. Therefore, we

    Moyo, Richard; Love, David; Mul, Marloes; Mupangwa, Walter; Twomlow, Steve

    Resource-poor smallholder farmers in the semi-arid Gwanda and Beitbridge districts face food insecurity on an annual basis due to a combination of poor and erratic rainfall (average 500 mm/a and 345 mm/a, respectively, for the period 1970-2003) and technologies inappropriate to their resource status. This impacts on both household livelihoods and food security. In an attempt to improve food security in the catchment a number of drip kit distribution programmes have been initiated since 2003 as part of an on-going global initiative aimed at 2 million poor households per year. A number of recent studies have assessed the technical performance of the drip kits in-lab and in-field. In early 2005 a study was undertaken to assess the impacts and sustainability of the drip kit programme. Representatives of the NGOs, local government, traditional leadership and agricultural extension officers were interviewed. Focus group discussions with beneficiaries and other villagers were held at village level. A survey of 114 households was then conducted in two districts, using a questionnaire developed from the output of the interviews and focus group discussions. The results from the study showed that the NGOs did not specifically target the distribution of the drip kits to poor members of the community (defined for the purpose of the study as those not owning cattle). Poor households made up 54% of the beneficiaries. This poor targeting of vulnerable households could have been a result of conditions set by some implementing NGOs that beneficiaries must have an assured water source. On the other hand, only 2% of the beneficiaries had used the kit to produce the expected 5 harvests over the 2 years, owing to problems related to water shortage, access to water and also pests and diseases. About 51% of the respondents had produced at least 3 harvests and 86% produced at least 2 harvests. Due to water shortages during the dry season 61% of production with the drip kit occurred during

    Coral microbiology is an expanding field, yet there is no standard DNA extraction protocol. Although many researchers depend on commercial extraction kits, no specific kit has been optimized for use with coral samples. Both soil and plant DNA extraction kits from MO BIO Laboratories, Inc., have been used by many research groups for this purpose. MO BIO recently replaced their PowerPlant® kit with an improved PowerPlantPro kit, but it was unclear how these changes would affect the kit’s use with coral samples. In order to determine which kit produced the best results, we conducted a comparison between the original PowerPlant kit, the new PowerPlantPro kit, and an alternative kit, PowerSoil, using samples from several different coral genera. The PowerPlantPro kit had the highest DNA yields, but the lack of 16S rRNA gene amplification in many samples suggests that much of the yield may be coral DNA rather than microbial DNA. The most consistent positive amplifications came from the PowerSoil kit.

    Full Text Available Mastocytosis is characterized by excessive proliferation and accumulation of mast cells in skin and/or other organs. Two forms of the disease, cutaneous and systemic mastocytosis, differ significantly in symptomatology and clinical course. KIT mutations play an important role in the pathogenesis of the disease. The presence of p.D816V KIT mutation was detected in the vast majority of adults with systemic mastocytosis. The role of KIT mutations in childhood-onset mastocytosis remains a matter of discussion. More recent studies have shown that cutaneous mastocytosis, which is the most common clinical manifestation of the disease in children, has a genetic background. In contrast to adults, different types of KIT mutations have been described in pediatric and familial mastocytosis. The understanding of the molecular mechanisms in mastocytosis enables targeted therapy using tyrosine kinase inhibitors.

    SwRI was contracted by NREL to evaluate three LPG conversion kits on a Chevrolet Lumina. The objective of the project was to measure the Federal Test Procedure (FTP) emissions and fuel economy of these kits, and compare their performance to gasoline-fueled operation and to each other. Varying LPG fuel blends allowed a preliminary look at the potential for fuel system disturbance. The project required kit installation and adjustment according to manufacturer`s instructions. A limited amount of trouble diagnosis was also performed on the fuel systems. A simultaneous contract from the Texas Railroad Commission, in cooperation with NREL, provided funds for additional testing with market fuels (HD5 propane and industry average gasoline) and hydrocarbon (HC) emissions speciation to determine the ozone-forming potential of LPG HC emissions. This report documents the procurement, installation, and testing of these LPG conversion kits.

  11. A change in structural integrity of c-Kit mutant D816V causes constitutive signaling.

    Science.gov (United States)

    Raghav, Pawan Kumar; Singh, Ajay Kumar; Gangenahalli, Gurudutta

    2018-02-17

    Several signaling pathways, ligands, and genes that regulate proliferative and self-renewal properties of the Hematopoietic Stem Cells (HSCs) have been studied meticulously. One of the signaling pathways that play a crucial role in the process of hematopoiesis is the Stem Cell Factor (SCF) mediated c-Kit pathway. The c-Kit is a Receptor Tyrosine Kinase (RTK), which is expressed in the cells including HSCs. It undergoes dimerization upon binding with its cognate ligand SCF. As a result, phosphorylation of the Juxtamembrane (JM) domain of c-Kit takes place at Tyr568 and Tyr570 residues. These phosphorylated residues become the docking sites for protein tyrosine phosphatases (PTPs) namely SHP-1 and SHP-2, which in turn cause dephosphorylation and negative regulation of the downstream signaling responsible for the cell proliferation. Interestingly, it has been reported that the mutation of c-Kit at D816V makes it independent of SCF stimulation and SHP-1/SHP-2 inhibition, thereby, causing its constitutive activation. The present study was commenced to elucidate the structural behavior of this mutation in the JM and A-loop region of c-Kit using Molecular Dynamics (MD) simulations of the wild-type and mutant c-Kit in unphosphorylated and phosphorylated states. The energy difference computed between the wild type and mutant (D816V) c-Kit, and protein-protein docking and complex analysis revealed the impact of this single residue mutation on the integrity dynamics of c-Kit that makes it independent of SHP-1/SHP-2 negative regulation.

    The Residential Lead-Based Paint Hazard Reduction Act (Title X) requires abatement and management of lead-based paint. The purpose of this study was to evaluate three chemical screening test kits using materials and methods from one study and subjecting the results to the statistical analysis of another. The three kits were used to predict the presence of lead in paint at ten weight concentrations from 0.04 to 3.97%. Paint was applied to four wood boards yielding a sample size of 40. Four boards were painted with lead-free paint and used as blanks. All of the boards were tested with the three test kits by an untrained individual having no knowledge of the actual lead content. Sensitivity, specificity, and false positive and negative rates were calculated for the test kit results. The manufactures` detection limits, the observed sensitivity ranged from 1.00 to 0.80, specificity ranged from 1.00 to 0.42, false positive ranged from 0 to 58%, and false negatives ranged from 0 to 20%. At the 0.5% Federal threshold level, the observed sensitivity ranged from 1.00 to 0.94, specificity ranged from 1.00 to 0.5, false positives ranged from 0 to 11.1%, and false negatives ranged from 0 to 20%. The observed false positive and false negative rates for all three kits were found to be significantly lower than those reported in a previous study. These results indicate that the kits perform very well at the Federal threshold, with two of the kits having false negative rates below 12.5% and false positive rates of 3.13%. These results indicate that these two kits would probably be acceptable screening tests for lead in paint.

    Blood circulating cell-free DNA (cfDNA) is becoming popular in the search of promising predictive and prognostic biomarkers. Among these biomarkers, cfDNA methylation markers have especially gained considerable attention. A significant challenge in the utilization of cfDNA methylation markers is the limited amount of cfDNA available for analyses; reportedly, bisulfite conversion (BSC) reduce cfDNA amounts even further. Nevertheless, few efforts have focused on ensuring high cfDNA conversion efficiency and recovery after BSC. To compare cfDNA recovery of different BSC methods, we compared 12 different commercially available BSC kits. We tested whether DNA recovery was affected by the molecular weight and/or quantity of input DNA. We also tested BSC efficiency for each kit. We found that recovery varied for DNA fragments of different lengths: certain kits recovered short fragments better than others, and only 3 kits recovered DNA fragments of BSC, a linear relation was found between input and recovery amount. Overall, mean recovery ranged between 9 and 32%, with BSC efficiency of 97-99.9%. When plasma cfDNA was used as input for BSC, recovery varied from 22% for the poorest and 66% for the best performing kits, while conversion efficiency ranged from 96 to 100% among different kits. In conclusion, clear performance differences exist between commercially available BSC kits, both in terms of DNA recovery and conversion efficiency. The choice of BSC kit can substantially impact the amount of converted cfDNA available for downstream analysis, which is critical in a cfDNA methylation marker setting.

    Radiation-induced hair graying is caused by irreversible defects in the self-renewal and/or development of follicular melanocyte stem cells in the hair follicles. Kit signaling is an essential growth and differentiation signaling pathway for various cell lineages including melanocytes, and its radioprotective effects have been shown in hematopoietic cells. However, it is uncertain whether Kit signaling exerts a radioprotective effect for melanocytes. In this study, we found that various loss-of-function mutations of Kit facilitate radiation-induced hair graying. In contrast, transgenic mice expressing the ligand for Kit (Kitl) in the epidermis have significantly reduced levels of radiation-induced hair graying. The X-ray doses used did not show a systemic lethal effect, indicating that the in vivo radiosensitivity of Kit mutants is mainly caused by the damaged melanocyte stem cell population. X-ray-damaged melanocyte stem cells seemed to take the fate of ectopically pigmented melanocytes in the bulge regions of hair follicles in vivo. Endothelin 3, another growth and differentiation factor for melanocytes, showed a lesser radioprotective effect compared with Kitl. These results indicate the prevention of radiation-induced hair graying by Kit signaling.

    The problems arising from increasing use of commercial kits in radioimmunoassay (RIA) and related fields are discussed. The problems arising in various RIAs differ according to the substance under test. The quality of individual components is often good, although methodology is often not optimal and contains short-cuts, which although commercially attractive, can lead to erroneous values and poor sensitivity and precision. Minor modification of methodology often leads to major improvements in sensitivity and precision, and this has been demonstrated in the case of three digoxin kits employing antibody-coated tube techniques and in four kits for thyrotropin (TSH) using different techniques. It has also been noted that in many imported quality control sera from the USA no values have been ascribed to European kits for the components listed, thus reducing these sera to the function of precision control. The deductions from this study are that a standardisation of kit components and assay methods is desirable in order to allow comparison of results between laboratories using different kits. (orig.)

    The receptor tyrosine kinase c-Kit is important for mast cell differentiation, proliferation, and cytokine release. Recently, we reported that c-Kit acts as an intermediate signalling molecule regulating IL-33-induced signalling and effector functions in mast cells. Here, we investigated the influence of c-Kit on the IL-1β-induced signalling and effector functions in HMC mast cell lines. HMC-cells were stimulated with IL-1β and the resulting signalling and cytokine responses were analysed. Furthermore, we used pharmacological inhibitors to investigate the relevance of several signalling molecules for the IL-1β-induced signalling and cytokine responses. Treatment of HMC-cells with the c-Kit inhibitor STI571 blocked the IL-1β-induced activation of Erk1/2 and JNK1/2 but not p38 and NFκB. Furthermore, inhibition of these signalling pathways blocked the IL-6 production in HMC-cells. These findings indicate that IL-1β-induced signalling in mast cells branches into c-Kit- dependent and -independent pathways, both relevant for IL-6 release. Therefore, c-Kit is an important regulator of IL-1 receptor 1-induced signalling and effector functions in HMC-cells. © 2011 Elsevier B.V. All rights reserved.

    Disaster Victim Identification (DVI) procedures and protocols have largely been standardised through the creation of, and amendments to, the INTERPOL DVI Guide. Whilst robust in addressing the recovery of mass fatality victims resulting from natural disasters, accidents and acts of terrorism, the guide does not explore the problematic issue of recovery of fatalities during active conflicts or peacekeeping operations where the environment may be hostile and the time taken to perform the task may impact significantly on the risk of injury or additional fatalities. This study tested the viability of the current UK style body recovery kit for use in a hostile environment simulation and compared its performance to two new bespoke kits specifically designed by the first author for this purpose. The aim was to recover the maximum amount of available physical evidence to support possible future judicial review, maintain respectful dignity for the deceased and focus on the safety of those fulfilling this task who may be operating on the front line. The kits were tested by military personnel experienced in hostile environment deployment. The trials showed that the time taken to record and recover the deceased could be reduced from 40 min using the standard DVI kit to just over 2 min using a bespoke kit. It was also shown that evidential recovery was not adversely affected and it is suggested that personal safety could be significantly enhanced if the proposed methodology and kit were adopted.

    We report a novel approach to bone marrow (BM) conditioning using c-kit-targeted chimeric antigen receptor T (c-kit CAR-T) cells in mice. Previous reports using anti-c-kit or anti-CD45 antibody linked to a toxin such as saporin have been promising. We developed a distinctly different approach using c-kit CAR-T cells. Initial studies demonstrated in vitro killing of hematopoietic stem cells by c-kit CAR-T cells but poor expansion in vivo and poor migration of CAR-T cells into BM. Pre-treatment of recipient mice with low-dose cyclophosphamide (125 mg/kg) together with CXCR4 transduction in the CAR-T cells enhanced trafficking to and expansion in BM (CAR-T cells were used in the Thy1.2-recipient mice, anti-Thy1.1 antibody could be used to deplete CAR-T cells in vivo before donor BM transplant. This achieved 20%-40% multilineage engraftment. We applied this conditioning to achieve an average of 28% correction of chronic granulomatous disease mice by wild-type BM transplant. Our findings provide a proof of concept that c-kit CAR-T cells can achieve effective BM conditioning without chemo-/radiotherapy. Our work also demonstrates that co-expression of a trafficking receptor can enhance targeting of CAR-T cells to a designated tissue. Published by Elsevier Inc.

    While capillary electrophoresis-based technologies have been the mainstay for human identity typing applications, there are limitations with this methodology's resolution, scalability, and throughput. Massively parallel sequencing (MPS) offers the capability to multiplex multiple types of forensically-relevant markers and multiple samples together in one run all at an overall lower cost per nucleotide than traditional capillary electrophoresis-based methods; thus, addressing some of these limitations. MPS also is poised to expand forensic typing capabilities by providing new strategies for mixture deconvolution with the identification of intra-STR allele sequence variants and the potential to generate new types of investigative leads with an increase in the overall number and types of genetic markers being analyzed. The beta version of the Illumina ForenSeq DNA Signature Prep Kit is a MPS library preparation method with a streamlined workflow that allows for targeted amplification and sequencing of 63 STRs and 95 identity SNPs, with the option to include an additional 56 ancestry SNPs and 22 phenotypic SNPs depending on the primer mix chosen for amplification, on the MiSeq desktop sequencer (Illumina). This study was divided into a series of experiments that evaluated reliability, sensitivity of detection, mixture analysis, concordance, and the ability to analyze challenged samples. Genotype accuracy, depth of coverage, and allele balance were used as informative metrics for the quality of the data produced. The ForenSeq DNA Signature Prep Kit produced reliable, reproducible results and obtained full profiles with DNA input amounts of 1ng. Data were found to be concordant with current capillary electrophoresis methods, and mixtures at a 1:19 ratio were resolved accurately. Data from the challenged samples showed concordant results with current DNA typing methods with markers in common and minimal allele drop out from the large number of markers typed on these

    Obtaining a genetic profile from pieces of evidence collected at a crime scene is the primary objective of forensic laboratories. New procedures, methods, kits, software or equipment must be carefully evaluated and validated before its implementation. The constant development of new methodologies for DNA testing leads to a steady process of validation, which consists of demonstrating that the technology is robust, reproducible, and reliable throughout a defined range of conditions. The present work aims to internally validate two new retrotransposon-based kits (InnoQuant ® HY and InnoTyper ® 21), under the working conditions of the Laboratório de Polícia Científica da Polícia Judiciária (LPC-PJ). For the internal validation of InnoQuant ® HY and InnoTyper ® 21 sensitivity, repeatability, reproducibility, and mixture tests and a concordance study between these new kits and those currently in use at LPC-PJ (Quantifiler ® Duo and GlobalFiler™) were performed. The results obtained for sensitivity, repeatability, and reproducibility tests demonstrated that both InnoQuant ® HY and InnoTyper ® 21 are robust, reproducible, and reliable. The results of the concordance studies demonstrate that InnoQuant ® HY produced quantification results in nearly 29% more than Quantifiler ® Duo (indicating that this new kit is more effective in challenging samples), while the differences observed between InnoTyper ® 21 and GlobalFiler™ are not significant. Therefore, the utility of InnoTyper ® 21 has been proven, especially by the successful amplification of a greater number of complete genetic profiles (27 vs. 21). The results herein presented allowed the internal validation of both InnoQuant ® HY and InnoTyper ® 21, and their implementation in the LPC-PJ laboratory routine for the treatment of challenging samples.

    This study investigated the correlation between KIT gene expression determined by immunohistochemistry and real-time polymerase chain reaction (RT-PCR) and the rate of tumour recurrence and tumour-related deaths in dogs affected with mast cell tumour (MCT). Kaplan-Meier curves were constructed to compare tumour recurrence and tumour-related death between patients. The log-rank test was used to check for significant differences between curves. KIT-I, KIT-II and KIT-III staining patterns were observed in 9 (11.11%), 50 (61.73%) and 22 (27.16%) tumours, respectively. Tumour recurrence rates and tumour-related deaths were not associated with KIT staining patterns (P = 0278, P > 0.05), KIT (P = 0.289, P > 0.05) or KIT ligand (P = 0.106, P > 0.05) gene expression. Despite the lack of association between KIT staining pattern and patient survival time, the results suggest a correlation between aberrant KIT localization and increased proliferative activity of MCTs. RT-PCR seems to be a sensible method for quantitative detection of KIT gene expression in canine MCT, although expressions levels are not correlated with prognosis. © 2013 Blackwell Publishing Ltd.

    Circulating exosomal microRNAs (miRNAs) are valuable biomarker candidates; however, information on the characterization and mutual agreement of commercial kits for circulating exosomal miRNA profiling is scarce. Here, we analyzed the advantages and weaknesses of four commonly used commercial kits for exosomal miRNA profiling and their application to the sample of serum and/or plasma, respectively. NanoSight and Western blotting were conducted to evaluate the efficiency and purity of the isolated exosomes. In our conditions, the size distribution of the isolated particles was appropriate (40-150 nm), and ExoQuick™ Exosome Precipitation Solution (EXQ) generated a relatively high yield of exosomes. Nevertheless, albumin impurity was ubiquitous for all the four kits, and Total Exosome Isolation for serum or plasma (TEI) yielded a relatively pure isolation. We further performed Illumina sequencing combined with RT-qPCR to determine the ability of these kits for miRNA profiling. There was significant correlation of the exosomal miRNA profile and specific miRNAs between kits, but with differences depending on methods. exoRNeasy Serum/Plasma Midi Kit (EXR) and EXQ performed better in the specific exosomal miRNAs recovery. Intraassay CVs for specific miRNA measurement were 0.88-3.82, 1.19-3.77, 0-2.70, and 1.23-9.11% for EXR, TEI, EXQ, and RIBO™ Exosome Isolation Reagent (REI), respectively. In each kit, serum yielded a higher abundance of exosomes and exosomal miRNAs than plasma, yet with more albumin impurity. In conclusion, our data provide some valuable guidance for the methodology of disease biomarker identification of circulation exosomal miRNAs.

    Full Text Available Background. Adipose tissue-derived mesenchymal stem cells (ASCs improve the regenerative ability and retention of fat grafts for breast reconstruction in cancer patients following mastectomy. However, ASCs have also been shown to promote breast cancer cell growth and metastasis. For the safety of ASC application, we aimed to identify specific markers for the subpopulation of ASCs that enhance the growth of breast cancer. Methods. ASCs and bone marrow-derived vascular endothelial progenitor cells (EPCs were isolated from Balb/c mice. c-Kit-positive (c-Kit+ or c-Kit-negative (c-Kit- ASCs were cocultured with 4T1 breast cancer cells. Orthotropic murine models of 4T1, EPCs + 4T1, and c-Kit+/-ASCs + 4T1/EPCs were established in Balb/c mice. Results. In coculture, c-Kit+ ASCs enhanced the viability and proliferation of 4T1 cells and stimulated c-Kit expression and interleukin-3 (IL-3 release. In mouse models, c-Kit+ASCs + 4T1/EPCs coinjection increased the tumor volume and vessel formation. Moreover, IL-3, stromal cell-derived factor-1, and vascular endothelial growth factor A in the c-Kit+ASCs + 4T1/EPCs coinjection group were higher than those in the 4T1, EPCs + 4T1, and c-Kit-ASCs + 4T1/EPCs groups. Conclusions. c-Kit+ ASCs may promote breast cancer growth and angiogenesis by a synergistic effect of c-Kit and IL-3. Our findings suggest that c-Kit+ subpopulations of ASCs should be eliminated in fat grafts for breast reconstruction of cancer patients following mastectomy.

    The objective of this study was to assess home-based care (HBC) kits and programs in South Africa to evaluate the feasibility of scaling up kit production and distribution. South African HBC organizations received structured questionnaires; key informant interviews and a literature review were completed to assess systems for production, distribution and supply of HBC kits. Meetings with stakeholders were held in two Provinces to share and analyze the study findings. The study team distributed questionnaires to 466 organizations and conducted interviews with representatives from 45 organizations, the Provincial Department of Health (DoH) and manufacturers of kits. All identifiable HBC organizations in South Africa were included in the survey. As a result 215 HBC organizations returned questionnaires; including non-governmental organizations (56%), community-based organizations (32%) and organizations affiliated with government health departments. Two types of kits were available: a home kit and a professional kit. The demand for HBC kits exceeded availability, kit contents and availability varied considerably and the supply chain was irregular. Kit production and distribution systems were fragmented. Replenishment of kit items was problematic. End-users are mostly caregivers who have not received adequate training on their use. The study shows that substantial work has been done by HBC organizations in South Africa to respond to the need for palliative care supplies within resource constraints. The growing demand for kits exceeds the supply. There is a need to improve the supply chain management of HBC kits, strengthen referral systems and links between community-based organizations and government departments, expand training opportunities for care givers, and develop monitoring and evaluation systems.

  11. Mutational profile of KIT and PDGFRA genes in gastrointestinal stromal tumors in Peruvian samples

    2015-02-01

    Full Text Available Introduction: Gastrointestinal stromal tumors (GISTs are mesenchymal neoplasms usually caused by somatic mutations in the genes KIT (c-KIT or PDGFRA. Mutation characterization has become an important exam for GIST patients because it is useful in predicting the response to the inhibitors of receptor tyrosine kinase (RTK. Objectives: The aim of this study was to determine the frequency of KIT and PDGFRA mutations in 25 GIST samples collected over two years at two national reference hospitals in Peru. There were 21 samples collected from the Instituto Nacional de Enfermedades Neoplásicas (INEN, national cancer center and 4 samples collected from Hospital A. Loayza. Methods and materials: In this retrospective study, we performed polymerase chain reaction (PCR amplification and deoxyribonucleic acid (DNA sequencing of KIT (exons 9, 11, 13, and 17 and PDGFRA (exons 12 and 18 genes in 20 FFPE (formalin-fixed, paraffin-embedded and 5 frozen GIST samples. Results: We report 21 mutations, including deletions, duplications, and missense, no mutations in 2 samples, and 2 samples with no useful DNA for further analysis. Eighty-six percent of these mutations were located in exon 11 of KIT, and 14 % were located in exon 18 of PDGFRA. Conclusions: Our study identified mutations in 21 out of 25 GIST samples from 2 referential national hospitals in Peru, and the mutation proportion follows a global tendency observed from previous studies (i.e., the majority of samples presented KIT mutations followed by a minor percentage of PDGFRA mutations. This study presents the first mutation data of the KIT and PDGFRA genes from Peruvian individuals with GIST.

  12. Changes in responsiveness to kit odours across pregnancy: relevance for the onset of maternal behaviour

    Full Text Available Virgin does are indifferent to foster kits but lesions to the main or accessory olfactory systems allow them to behave “maternally” (i.e., they crouch over the litter and allow suckling. This suggests that kit-derived olfactory cues are aversive to virgins but not to lactating does. We hypothesised that the valence of such olfactory cues changes throughout gestation so that, at parturition, does are attracted to the newborn and can then show placentophagia, clean the kits and nurse them. To explore this hypothesis we exposed does to 2 nest boxes containing a variety of pup-derived vs. “neutral” odours, quantifying the number of sniffs and entrances to each box over 60 min. Virgins, confronted with 2 different types of contrasts, showed no significant differences in the number of sniffs or entrances directed at any of the 2 boxes. Pregnant rabbits sniffed the “kit-odour” box significantly more than the “neutral” one as early as gestation day 7, depending on the animals’ experience with the experimental setup and kit odours as virgins. The number of sniffs declined in late pregnancy in all groups. Entrances into the “kit-odour” box were few and significantly higher than those shown towards the “neutral” box only in 1 group. Our findings agree with a correlation between a shift in the valence of kit-derived olfactory cues and the hormonal changes known to occur throughout pregnancy. The relevance of this phenomenon for the onset of maternal responsiveness at parturition is discussed.

    The surface of the KIT-6 zeolite was modified with different amounts of Ni and V to promote the catalytic properties for CO methanation. A series of xNi-yV/KIT-6 with various Ni and V contents were prepared by the incipient-wetness impregnation method. The modified surfaces were characterized using N2 adsorption-desorption, Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), hydrogen temperature-programmed reduction (H2-TPR), Fourier transformed infrared spectroscopy (FT-IR), Raman, X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), and energy-dispersive X-ray spectroscopy (EDX), respectively. The characterization results illustrated that the modification of V species was able to significantly promote low-temperature catalytic performance below 350 °C compared to that of unmodified Ni/KIT-6, which was likely due to an increase in the H2 uptake accompanied by enhanced CO dissociation derived from stronger electron transfer from V species to Ni0. Correspondingly, the xNi-yV/KIT-6 catalysts exhibited a distinct enhancement in CO conversion, CH4 selectivity and CH4 yield over unmodified Ni/KIT-6. Among all catalysts, 20Ni-2V/KIT-6 showed the best catalytic performance, corresponding to nearly 100% CO conversion and 85% CH4 yield at a low temperature of 300 °C. Furthermore, 20Ni-2V/KIT-6 presented enhanced coking-resistant and anti-sintering properties during a 60h-lifetime test at 500 °C and 1 atm with a high weight hourly space velocity (WHSV) of 60000 ml/g/h.

    To implement quality screening in a blood service requires the presence of screening strategy with a clear algorithm and supporting standard operating procedures (SOPs), skilled and motivated human resource to perform testing, infrastructure, regular available test kits, and other supplies. In developing countries, smooth supply chain management of critical transfusion transmissible infections (TTIs) screening reagents is a challenge. Therefore, managing the little available kits by knowing the rate of consumption, good forecasting, and monitoring expiry date may be a key in ensuring regular supply. Test kit monitoring tool (TKMT) for Vironostika HIV Uni-Form kit/192 1&2 Ag/Ab, Genedia kits for HBsAg and HCV, and RPR for syphilis was developed to track these reagents. This excel tool was developed to assess received reagents, quantity used, quantity remaining, and date of expiration. The tool was evaluated by assessing rerun for each test kits, match tests conducted with blood units tested, adherence to the principle of first in-first out (FIFO), and quantity remaining in the center against the need. The mean rerun for HIV ELISA Vironistika uniform II Ag/Ab observed over expected was 6.9% (n = 3.8) than 2.4% (n = 1.3), HBsAg was 9.9% (n = 5.7) than 6.7% (3.5) (expected), Genedia for HCV was 1.3% (n = 0.7) than 0.5% (n = 0.3), and RPR test for syphilis 3.3% (n = 1.5) than 0.5%. During implementation, TKMT managed to detect expiring kits in the zonal blood transfusion centers. A tool-like TKMT may capture other supplies within blood when expanded. Monitoring of supplies may enable blood service actual accounting and in forecasting supplies and reagents. © 2013 Wiley Periodicals, Inc.

    Poor quality lighting impedes astronomy research and our right to see a starry night sky. It creates safety issues, affects human circadian sensitivities, disrupts ecosystems, and wastes billions of dollars/year in energy consumption. It also leads to excess carbon emissions. How do you change the mindset of society that is used to turning night into day? You educate the next generation on quality lighting.As an outcome of the International Year of Light 2015, the National Optical Astronomy Observatory’s Education and Public Outreach group has produced a Quality Lighting Teaching (QLT) Kit. The kits are designed around problem-based learning scenarios. The kit’s six activities allow students to address real lighting problems that relate to wildlife, sky glow, aging eyes, energy consumption, safety, and light trespass. The activities are optimized for 11-14 year olds but can be expanded to younger and older. All materials are in both English and Spanish. Most of the activities can be done within in a few minutes during class or afterschool and as stations or as stand-alones. Everything you need for the six activities is included in the kit. Tutorial videos on how to do the activities can be found at www.noao.edu/education/qltkit.php. Ninety-two out of one hundred kits have been distributed in thirty-two countries through SPIE (the International Society for Optical Engineering), CIE (the International Commission on Illuminations), OSA (the Optical Society), IDA (the International Dark Sky Association), and the IAU OAD–Office of Astronomy Development. Successful feedback is promoting a choice between commercializing the kit or gaining further grants to build more kits. A plan is being considered to distribute kits to observatories around the world, hence helping to reduce the effects of one of the three threats to observational astronomy through awareness and action.

  16. Performance evaluation of kits for bisulfite-conversion of DNA from tissues, cell lines, FFPE tissues, aspirates, lavages, effusions, plasma, serum, and urine.

    Full Text Available DNA methylation analyses usually require a preceding bisulfite conversion of the DNA. The choice of an appropriate kit for a specific application should be based on the specific performance requirements with regard to the respective sample material. In this study, the performance of nine kits was evaluated: EpiTect Fast FFPE Bisulfite Kit, EpiTect Bisulfite Kit, EpiTect Fast DNA Bisulfite Kit (Qiagen, EZ DNA Methylation-Gold Kit, EZ DNA Methylation-Direct Kit, EZ DNA Methylation-Lightning Kit (Zymo Research, innuCONVERT Bisulfite All-In-One Kit, innuCONVERT Bisulfite Basic Kit, innuCONVERT Bisulfite Body Fluids Kit (Analytik Jena. The kit performance was compared with regard to DNA yield, DNA degradation, DNA purity, conversion efficiency, stability and handling using qPCR, UV, clone sequencing, HPLC, and agarose gel electrophoresis. All kits yielded highly pure DNA suitable for PCR analyses without PCR inhibition. Significantly higher yields were obtained when using the EZ DNA Methylation-Gold Kit and the innuCONVERT Bisulfite kits. Conversion efficiency ranged from 98.7% (EpiTect Bisulfite Kit to 99.9% (EZ DNA Methylation-Direct Kit. The inappropriate conversion of methylated cytosines to thymines varied between 0.9% (innuCONVERT Bisulfite kits and 2.7% (EZ DNA Methylation-Direct Kit. Time-to-result ranged from 131 min (innuCONVERT kits to 402 min (EpiTect Bisulfite Kit. Hands-on-time was between 66 min (EZ DNA Methylation-Lightning Kit and 104 min (EpiTect Fast FFPE and Fast DNA Bisulfite kits. Highest yields from formalin-fixed and paraffin-embedded (FFPE tissue sections without prior extraction were obtained using the innuCONVERT Bisulfite All-In-One Kit while the EZ DNA Methylation-Direct Kit yielded DNA with only low PCR-amplifiability. The innuCONVERT Bisulfite All-In-One Kit exhibited the highest versatility regarding different input sample materials (extracted DNA, tissue, FFPE tissue, cell lines, urine sediment, and cellular fractions

    1978-01-01

    Results with three commercial folate radioassay kits [Bio-Rad, New England Nuclear (NEN), and RIA Products] were compared with those by microbiological assay for more than 200 samples of human serum and whole blood. All but one kit (NEN) compared favorably with the microbiological assay for serum samples, although there were notable diagnostic discrepancies. Two kits (NEN and Bio-Rad) were tested on whole-blood samples; both yielded values significantly higher than those by microbiological assay. The frequency distributions of erythrocyte folate data differed strikingly between the two kits; the NEN method yielded a much narrower range of normal values than did either the Bio-Rad or the microbiological assay. Radioassay kits appear to be suitable diagnostic agents for serum folate, if the behavior of a particular kit is investigated thoroughly before its routine use. However, the diagnostic value of radioassays of erythrocyte folate needs to be validated

    DNA identification of human remains is often necessary when decedents are skeletonized; however, poor DNA recovery and polymerase chain reaction (PCR) inhibition are frequently encountered, a situation exacerbated by burial. In this research, the utility of integrating soil DNA isolation kits into buried skeletal DNA analysis was evaluated and compared to a standard human DNA extraction kit and organic extraction. The soil kits successfully extracted skeletal DNA at quantities similar to standard methods, although the two kits tested, which differ mechanistically, were not equivalent. Further, the PCR inhibitors calcium and humic acid were effectively removed using the soil kits, whereas collagen was less so. Finally, concordant control region sequences were obtained from human skeletal remains using all four methods. Based on these comparisons, soil DNA isolation kits, which quickened the extraction process, proved to be a viable extraction technique for skeletal remains that resulted in positive identification of a decedent. © 2015 American Academy of Forensic Sciences.

    Cutaneous mast cell tumors (MCTs) are among the most frequent malignant tumors in dogs and Boxer breed dogs have a higher incidence of this disease. Ki67 staining and KIT staining are widely used to predict natural behavior in canine MCT but no previous study has evaluated double staining of these proteins as a prognostic factor. Based on biological behavior predictors in canine MCT, the purpose of this study was to determine the Ki67 proliferative index in KIT positive cells using double stain immunohistochemistry technique. Sixty-nine MCTs from Boxer dogs were selected and a tissue microarray was constructed for the double stained immunohistochemistry. Double positivity (Ki67(+)/KIT(+)) was observed in 20/69 (29%) MCT, with a mean of 9.06 double positive cells per tissue core (range 0.48%-43.97%) and Ki67(-)/KIT(+) animals had a longer survival time than Ki67(+)/KIT(+) animals (p=0.03).

    Hair graying, an age-associated process of unknown etiology, is characterized by a reduced number and activity of hair follicle (HF) melanocytes. Stem cell factor (SCF) and its receptor c-kit are important for melanocyte survival during development, and mutations in these genes result in unpigmented hairs. Here we show that during cyclic HF regeneration in C57BL/6 mice, proliferating, differentiating, and melanin-producing melanocytes express c-kit, whereas presumptive melanocyte precursors do not. SCF overexpression in HF epithelium significantly increases the number and proliferative activity of melanocytes. During the induced hair cycle in C57BL/6 mice, administration of anti-c-kit antibody dose-dependently decreases hair pigmentation and leads to partially depigmented (gray) or fully depigmented (white) hairs, associated with significant decreases in melanocyte proliferation and differentiation, as determined by immunostaining and confocal microscopy. However, in the next hair cycle, the previously treated animals grow fully pigmented hairs with the normal number and distribution of melanocytes. This suggests that melanocyte stem cells are not dependent on SCF/c-kit and when appropriately stimulated can generate melanogenically active melanocytes. Therefore, the blockade of c-kit signaling offers a fully reversible model for hair depigmentation, which might be used for the studies of hair pigmentation disorders.

    Melanoma cells that express stem cell marker CD271 are shown to form tumors when transplanted into nude or immunodeficient mice. These tumors have a higher metastatic potential and worse prognosis than melanomas resulting from transplantation of CD271-negative cells. We studied stem cell markers (CD271, c-kit, SOX1O) in melanomas, correlating their presence with prognostic factors and outcome. A total of 82 melanomas in tissue microarrays were immunostained for CD271, c-kit, and SOX10. Results were correlated with clinicopathologic prognostic parameters (Breslow depth of invasion, Clark level, sentinel lymph node status, and pathologic stage) and outcome (recurrence, metastases, and death). Of the 82 melanomas, CD271 was expressed in 18 (21%), c-kit in 47 (57%), and SOX10 in all (100%). CD271 does show correlation with metastases (P=0.05). c-kit is associated with favorable prognostic parameters [Breslow depth (Pmelanomas studied. In conclusion, CD271 expression in melanomas is associated with increased frequency of metastases, and c-kit immunoreactivity is associated with favorable prognostic parameters and improved outcome.

    Full Text Available Introduction and objective. Mycobacteria have been isolated from almost all types of natural waters, as well as from man-made water distribution systems. Detection of mycobacteria using PCR has been described in different types of water; however, currently, there is no standardised protocol for the processing of large volumes of water. Material and Methods. In the present study, different filtering methods are tested and optimised for tap or river water filtration up to 10 L, as well as filter processing and DNA isolation using four commercially available kits. Results. The PowerWater DNA isolation kit (MoBio, USA, together with a kit used for soil and other environmental samples (PowerSoil DNA isolation kit, MoBio, had the highest efficiency. Filtration of 10 L of water and elution of the filter in PBS with the addition of 0.05% of Tween 80 is suggested. Conclusions. The described protocol for filter elution is recommended, and the use of the PowerWater DNA isolation kit for the highest mycobacterial DNA yield from water samples. The described protocol is suitable for parallel detection of mycobacteria using cultivation.

    Introduction: Tris(4,6-dimethoxysalicylaldimine)-N,N'-bis(3-aminopropyl) -N,N'-ethylenediamine (BAPEN), a tris(salicylaldimine) derivative, is a heart positron emission tomography (PET) agent when labeled with 68 Ga. However, its labeling requires complicated and time-consuming procedures. In this study, the authors formulated a new BAPEN kit for convenient 68 Ga labeling. Methods: BAPEN (0.25 mg) kits were prepared by dispensing its solution in 1 M sodium acetate buffer (pH 5.5) into sterile vials and lyophilization. The prepared kits were labeled with generator-eluted 68 Ga in 0.1 N HCl. Stability in human serum was tested. Expiration date was determined by accelerated testing according to US Food and Drug Administration guidelines. A Biodistribution study was performed in normal mice after injection via tail vein. Results: The prepared kits achieved radiolabeling efficiencies in excess of 95% and showed a shelf-life of 98 days at 25 deg. C and 64.3 months at 4 deg. C. 68 Ga-BAPEN was found to be stable in human serum at 37 deg. C for at least 1 h. Furthermore, a biodistribution study revealed high heart uptake (10.8% ID/g, 1 h). Conclusions: The authors developed a BAPEN kit for convenient labeling with 68 Ga. The 68 Ga-BAPEN showed high stability and excellent biodistribution results in normal mice, which is required for myocardial PET imaging.

    The San Joaquin kit fox ( Vulpes macrotis mutica) is a federally endangered small carnivore whose distribution is limited to the San Joaquin Valley in central California. Population decline is due to profound habitat loss, and conservation of all remaining populations is critical. A robust urban population occurs in the city of Bakersfield. In spring of 2013, putative cases of mange were reported in this population. Mites from affected animals were confirmed to be Sarcoptes scabiei morphologically and by DNA sequencing. By the end of 2014, 15 cases of kit foxes with mange had been confirmed. As with other species, sarcoptic mange in kit foxes is characterized by intense pruritus and dermatitis, caused by mites burrowing into the epidermal layers, as well as alopecia, hyperkeratosis, and encrustations, secondary bacterial infections, and finally extreme morbidity and death. Of the 15 cases, six foxes were found dead, six were captured but died during attempted rehabilitation, and three were successfully treated. We have no evidence that untreated kit foxes can recover from mange. Sarcoptic mange constitutes a significant threat to the Bakersfield kit fox population and could pose an even greater threat to this imperiled species if it spreads to populations in nearby natural lands.

  6. Land Use as a Driver of Patterns of Rodenticide Exposure in Modeled Kit Fox Populations.

    Directory of Open Access Journals (Sweden)

    Theresa M Nogeire

    Full Text Available Although rodenticides are increasingly regulated, they nonetheless cause poisonings in many non-target wildlife species. Second-generation anticoagulant rodenticide use is common in agricultural and residential landscapes. Here, we use an individual-based population model to assess potential population-wide effects of rodenticide exposures on the endangered San Joaquin kit fox (Vulpes macrotis mutica. We estimate likelihood of rodenticide exposure across the species range for each land cover type based on a database of reported pesticide use and literature. Using a spatially-explicit population model, we find that 36% of modeled kit foxes are likely exposed, resulting in a 7-18% decline in the range-wide modeled kit fox population that can be linked to rodenticide use. Exposures of kit foxes in low-density developed areas accounted for 70% of the population-wide exposures to rodenticides. We conclude that exposures of non-target kit foxes could be greatly mitigated by reducing the use of second-generation anticoagulant rodenticides in low-density developed areas near vulnerable populations.

  7. Exclusion of EDNRB and KIT as the basis for white spotting in Border Collies.

    Metallinos, D; Rine, J

    2000-01-01

    White spotting patterns in mammals can be caused by mutations in the genes for the endothelin B receptor and c-Kit, whose protein products are necessary for proper migration, differentiation or survival of the melanoblast population of cells. Although there are many different dog breeds that segregate white spotting patterns, no genes have been identified that are linked to these phenotypes. An intercross was generated from a female Newfoundland and a male Border Collie and the white spotting phenotypes of the intercross progeny were evaluated by measuring percentage surface area of white in the puppies. The Border Collie markings segregated as a simple autosomal recessive (7/25 intercross progeny had the phenotype). Two candidate genes, for the endothelin B receptor (EDNRB) and c-Kit (KIT), were evaluated for segregation with the white spotting pattern. Polymorphisms between the Border Collie and Newfoundland were identified for EDNRB using Southern analysis after a portion of the canine gene had been cloned. Polymorphisms for KIT were identified using a microsatellite developed from a bacterial artificial chromosome containing the canine gene. Both EDNRB and KIT were excluded as a cause of the white spotting pattern in at least two of the intercross progeny. Although these genes have been implicated in white spotting in other mammals, including horses, pigs, cows, mice and rats, they do not appear to be responsible for the white spotting pattern found in the Border Collie breed of dog.

    NEMO was the "Network of Excellence in Micro-Optics" granted in the "Sixth Framework Program" of the European Union. It aimed at providing Europe with a complete Micro-Optics food-chain, by setting up centers for optical modeling and design; measurement and instrumentation; mastering, prototyping and replication; integration and packaging and reliability and standardization. More than 300 researchers from 30 groups in 12 countries participated in the project. One of the objectives of NEMO was to spread excellence and disseminate knowledge on micro-optics and micro-photonics. To convince pupils, already from secondary school level on, about the crucial role of light and micro-optics and the opportunities this combination holds, several partners of NEMO had collaborate to create this Educational Kit. In Spain the partner involved in this aim was the "Microoptics and GRIN Optics Group" at the University of Santiago of Compostela (USC). The educational kits provided to the Secondary School were composed by two plastic cards with the following microoptical element: different kinds of diffractive optical elements or DOES and refractive optical elements or ROEs namely arrays of micro-lenses. The kit also included a DVD with a handbook for performing the experiments as well as a laser pointer source. This kit was distributed free of charge in the countries with partners in NEMO. In particular in Spain was offered to around 200 Secondary School Centers and only 80 answered accepting evaluate the kit.

    A commercial ''AMERWELL AFP RIA-kit'' was fundamentally and clinically evaluated. The present assay kit was simple to treat for measurement. Laboratory findings were encouraging enough to use it in routine practice. There were extremely small quantities of radioactive waste. A good correlation was observed between the present assay kit and ''AFP EIKEN RIA kit''. The lower detection limit for AFP in serum was 1.5 IU/ml. The upper limit for serum AFP was 3 IU/ml in normal controls (n = 112). Serum AFP concentrations were 1.5 - 34.8 IU/ml for acute hepatitis, 1.5 - 191.4 IU/ml for chronic hepatitis, 1.5 - 398.1 IU/ml for liver cirrhosis, and 1.5 - 268,350 IU/ml for hepatocellular carcinoma. The positive rates of AFP for these diseases were 46 %, 47 %, 79 %, and 93 %, respectively. Falling concentrations of serum AFP were associated with favorable management. The results indicate the usefulness of the present assay kit in the diagnosis of various liver diseases, understanding of pathophysiology, and postoperative management for hepatocellular carcinoma.

    2004-08-20

    In a retrospective analysis of 203 patients with small cell lung cancer (SCLC), we examined the prognostic value of c-kit expression on survival. Expression of c-kit was examined immunohistochemically in formalin-fixed, paraffin-embedded tissue sections. c-kit was observed in 87.7% of SCLC tumors. Using the Kaplan-Meier model, we found that lack of c-kit expression was associated with significantly shorter survival time compared to the presence of c-kit expression (mean survival 151 +/- 27 vs. 358 +/- 49 days, p = 0.0084). Moreover, the proportion of c-kit(+) cells within the tumor was also related to survival time. Patients with tumors in which >75% of cells stained positive for c-kit had a mean overall survival time of 424 (+/-72) compared to 295 (+/-67) days for patients with 25-75% c-kit(+) tumor cells. Patients with tumors containing model showed that the proportion of c-kit(+) cells within the tumor specimen was one of 3 independent prognostic parameters (p = 0.004) for overall survival next to TNM classification (p = 0.001) and performance status (p < 0.001).

    Mutations of the receptor tyrosine kinase KIT are linked to certain cancers such as gastrointestinal stromal tumors (GISTs). Biophysical, biochemical, and structural studies have provided insight into the molecular basis of resistance to the KIT inhibitors, imatinib and sunitinib. Here, solution-phase hydrogen/deuterium exchange (HDX) and direct binding mass spectrometry experiments provide a link between static structure models and the dynamic equilibrium of the multiple states of KIT, supporting that sunitinib targets the autoinhibited conformation of WT-KIT. The D816H mutation shifts the KIT conformational equilibrium toward the activated state. The V560D mutant exhibits two low energy conformations: one is more flexible and resembles the D816H mutant shifted toward the activated conformation, and the other is less flexible and resembles the wild-type KIT in the autoinhibited conformation. This result correlates with the V560D mutant exhibiting a sensitivity to sunitinib that is less than for WT KIT but greater than for KIT D816H. These findings support the elucidation of the resistance mechanism for the KIT mutants.

    Full Text Available Receptor tyrosine kinase KIT controls many signal transduction pathways and represents a typical allosterically regulated protein. The mutation-induced deregulation of KIT activity impairs cellular physiological functions and causes serious human diseases. The impact of hotspots mutations (D816H/Y/N/V and V560G/D localized in crucial regulatory segments, the juxtamembrane region (JMR and the activation (A- loop, on KIT internal dynamics was systematically studied by molecular dynamics simulations. The mutational outcomes predicted in silico were correlated with in vitro and in vivo activation rates and drug sensitivities of KIT mutants. The allosteric regulation of KIT in the native and mutated forms is described in terms of communication between the two remote segments, JMR and A-loop. A strong correlation between the communication profile and the structural and dynamical features of KIT in the native and mutated forms was established. Our results provide new insight on the determinants of receptor KIT constitutive activation by mutations and resistance of KIT mutants to inhibitors. Depiction of an intra-molecular component of the communication network constitutes a first step towards an integrated description of vast communication pathways established by KIT in physiopathological contexts.

    The recent progress in sensitive KIT D816V mutation analysis suggests that mutation analysis of peripheral blood (PB) represents a promising diagnostic test in mastocytosis. However, there is a need for systematic assessment of the analytical sensitivity and specificity of the approach in order...... to establish its value in clinical use. We therefore evaluated sensitive KIT D816V mutation analysis of PB as a diagnostic test in an entire case-series of adults with mastocytosis. We demonstrate for the first time that by using a sufficiently sensitive KIT D816V mutation analysis, it is possible to detect...... the mutation in PB in nearly all adult mastocytosis patients. The mutation was detected in PB in 78 of 83 systemic mastocytosis (94%) and 3 of 4 cutaneous mastocytosis patients (75%). The test was 100% specific as determined by analysis of clinically relevant control patients who all tested negative. Mutation...

    Hyperspectral imaging (HSI) has been used for over two decades in laboratory research, academic, environmental and defense applications. In more recent time, HSI has started to be adopted for commercial applications in machine vision, conservation, resource exploration, and precision agriculture, to name just a few of the economically viable uses for the technology. Corning Incorporated (Corning) has been developing and manufacturing HSI sensors, sensor systems, and sensor optical engines, as well as HSI sensor components such as gratings and slits for over a decade and a half. This depth of experience and technological breadth has allowed Corning to design and develop unique HSI spectrometers with an unprecedented combination of high performance, low cost and low Size, Weight, and Power (SWaP). These sensors and sensor systems are offered with wavelength coverage ranges from the visible to the Long Wave Infrared (LWIR). The extremely low SWaP of Corning's HSI sensors and sensor systems enables their deployment using limited payload platforms such as small unmanned aerial vehicles (UAVs). This paper discusses use of the Corning patented monolithic design Offner spectrometer, the microHSI™, to build a highly compact 400-1000 nm HSI sensor in combination with a small Inertial Navigation System (INS) and micro-computer to make a complete turn-key airborne remote sensing payload. This Selectable Hyperspectral Airborne Remote sensing Kit (SHARK) has industry leading SWaP (1.5 lbs) at a disruptively low price due, in large part, to Corning's ability to manufacture the monolithic spectrometer out of polymers (i.e. plastic) and therefore reduce manufacturing costs considerably. The other factor in lowering costs is Corning's well established in house manufacturing capability in optical components and sensors that further enable cost-effective fabrication. The competitive SWaP and low cost of the microHSI™ sensor is approaching, and in some cases less than the price

    2016-11-01

    Diffusion magnetic resonance imaging (dMRI) techniques are receiving increasing attention due to their ability to characterize the arrangement map of white matter in vivo. However, the existing toolkits for dMRI analysis that have accompanied this surge possess noticeable limitations, such as large installation size, an incomplete pipeline, and a lack of cross-platform support. In this work, we developed a light, one-stop, cross-platform solution for dMRI data analysis, called DiffusionKit. It delivers a complete pipeline, including data format conversion, dMRI preprocessing, local reconstruction, white matter fiber tracking, fiber statistical analyses and various visualization schemes. Furthermore, DiffusionKit is a self-contained executable toolkit, without the need to install any other software. The DiffusionKit package is implemented in C/C++ and Qt/VTK, is freely available at http://diffusion.brainnetome.org and https://www.nitrc.org/projects/diffusionkit. The website of DiffusionKit includes test data, a complete tutorial and a series of tutorial examples. A mailing list has also been established for update notification and questions and answers. DiffusionKit provides a full-function pipeline for dMRI data analysis, including data processing, modeling and visualization. Additionally, it provides both a graphical user interface (GUI) and command-line functions, which are helpful for batch processing. The standalone installation package has a small size and cross-platform support. DiffusionKit provides a complete pipeline with cutting-edge methods for dMRI data analysis, including both a GUI interface and command-line functions. The rich functions for both data analysis and visualization will facilitate and benefit dMRI research. Copyright © 2016 Elsevier B.V. All rights reserved.

    Human papillomavirus (HPV) is the aetiological agent for cervical cancer and genital warts. Concurrent HPV and HIV infection in the South African population is high. HIV positive (+) women are often infected with multiple, rare and undetermined HPV types. Data on HPV incidence and genotype distribution are based on commercial HPV detection kits, but these kits may not detect all HPV types in HIV + women. The objectives of this study were to (i) identify the HPV types not detected by commercial genotyping kits present in a cervical specimen from an HIV positive South African woman using next generation sequencing, and (ii) determine if these types were prevalent in a cohort of HIV-infected South African women. Total DNA was isolated from 109 cervical specimens from South African HIV + women. A specimen within this cohort representing a complex multiple HPV infection, with 12 HPV genotypes detected by the Roche Linear Array HPV genotyping (LA) kit, was selected for next generation sequencing analysis. All HPV types present in this cervical specimen were identified by Illumina sequencing of the extracted DNA following rolling circle amplification. The prevalence of the HPV types identified by sequencing, but not included in the Roche LA, was then determined in the 109 HIV positive South African women by type-specific PCR. Illumina sequencing identified a total of 16 HPV genotypes in the selected specimen, with four genotypes (HPV-30, 74, 86 and 90) not included in the commercial kit. The prevalence's of HPV-30, 74, 86 and 90 in 109 HIV positive South African women were found to be 14.6%, 12.8%, 4.6% and 8.3% respectively. Our results indicate that there are HPV types, with substantial prevalence, in HIV positive women not being detected in molecular epidemiology studies using commercial kits. The significance of these types in relation to cervical disease remains to be investigated.

Methods: 99 Tc m -TRODAT-1 kit was prepared by the following formulation: 50 μg TRODAT-1, 70 μg SnC1 2 ·2H 2 0, 1.0 mg EDTA-2Na, 17.64 mg Na 2 HPO 4 ·12 H 2 0, 2.37 mg KH 2 PO 4 and 10 mg sodium glucoheptonate (GH). Radiolabelling yield (or radiochemical purity) was determined by thin layer chromatograph (TLC). A series of studies were performed to optimize labeling efficiency of 99 Tc m -TRODAT-1 kit. Varying the amount of TRODAT-1, SnCl 2 ·2H 2 0, EDTA-2Na and GH, labeling yield was measured by TLC. (2) Varying the pH value, radiochemical purity was also determined by TLC. Results: Labeling yield of 99 Tc m -TRODAT-1 kit was over 90% (n>10). The optimal amounts of each ingredient were: TRODAT-1 20 - 200 μg, SnCl 2 4-100 μg, EDTA-2Na 0.5-2.0 mg, GH 1-20 mg and pH4.5-8.3. The kit was stable within 3 month when stored at 25 degree C or 1 year at -18 degree C as evaluated by labeling yield. Conclusions: 99 Tc m -TRODAT-l kit of new formulation was successfully prepared. Labeling yield and radiochemical purity were all over 90%, with good stability. (authors)

    A new clean room has been designed and constructed at Radiopharmaceuticals Programme, BRIT keeping in view the functional aspects for the production of 'cold' kits for the preparation of 99m Tc radiopharmaceuticals for supply to nuclear medicine centers and is in operation, since October, 2008. This clean room is the first clean room in the country designed exclusively for cold kit production. The clean room was validated and trial batches were produced and quality controlled prior to put it in regular production operation. The clean environment is maintained by separate AHU (air handling unit) located out side the clean room. A technical crew maintain the AHU unit and maintain record of parameters such as humidity, air flow, blower speed, chiller temperature etc. During a typical batch production not more than two persons are present in the formulation room. The formulated solution (filtered through 0.22μ membrane filter) is passed though a pass box between the formulation and dispensing area. The no. of people allowed in the dispensing area which is a critical area of class 100 is restricted to not more than four that too no person is allowed to be in between direct flow of HEPA filtered air and the dispensing table. The number of vials to be dispensed is arranged in trays and 1 ml of the formulated sterile solution is dispensed into each vial and the vials are transferred in to the lyophilization chamber. Sterile vials are introduced into class 100 area and the vials are removed after lyophilization though a pass box. After lyophilization vials are sealed with aluminum caps and stored at 2-10 deg C. Since the commissioning of the new clean room, about 120 batches of 10 different kit products were prepared and 1,20,000 kit vials were supplied to various hospitals for nuclear medicine investigation

    Full Text Available Gliosarcomas are rare and poorly characterized malignant brain tumors that exhibit a biphasic tissue pattern with areas of gliomatous and sarcomatous differentiation. These tumors are histological variants of glioblastoma, displaying a similar genetic profile and dismal prognosis. Up-regulation of PDGFR subfamily of tyrosine kinase members, PDGFR-α and c-Kit, and their intracellular effectors RAS/RAF/MAPK has a crucial role in the cancer development. In addition, signal transduction mediated by activating mutations of c-Kit and PDGFR can be effectively blocked by specific tyrosine kinase inhibitors, such as Imatinib mesylate. The aim of this study was to characterize the molecular alterations of PDGFR signaling in gliosarcomas. Six cases were analyzed by immunohistochemistry for the expression of PDGFR-α, c-Kit and their ligands PDGF-A and SCF, respectively. The cases were further evaluated for the presence of activating mutations of PDGFR-α (exons 12 and 18 and c-kit (exons 9, 11, 13, and 17, as well as B-RAF (exons 11 and 15. Expression of PDGF-A was found in all cases and co-expression of PDGFR-α was observed in three cases. Four cases showed expression of SCF, and c-Kit was observed only in one case that also expressed SCF. Generally, immunoreaction predominates in the glial component. The mutational analysis of PDGFR-α showed the presence of an IVS17-50insT intronic insertion in two cases, one of them also with a 2472C > T silent mutation; this silent mutation was also found in another case. Glioma cell line analysis of IVS17-50insT insertion showed no influence on PDGFR-α gene splicing. No mutations were detected in c-kit and B-RAF oncogenes. Our Results indicate that activating mutations of PDGFR-α, c-kit and B-RAF are absent in gliosarcomas. Nevertheless, the presence of a PDGFR-a/PDGFA and c-Kit/SCF autocrine/paracrine stimulation loop in a proportion of cases, supports the potential role of specific tyrosine kinase inhibitors in

    A simple and inexpensive method for the estimation of stannous ion, Sn(II), in radiopharmaceutical kits is described. The method used is a potentiometric titration of Sn(II) in 1 N HCl medium, using potassium iodate as the oxidizing agent in an atmosphere of nitrogen. The apparatus includes a pH meter, a platinum electrode, and a simple titration cell. Several commonly used radiopharmaceutical kits were analyzed for their Sn(II) content using this method. These studies indicate that the procedure can be used, as a routine quantitative test for the Sn(II) content of various sup(99m)Tc-labeled radiopharmaceuticals. (orig.)

    The number of RIA kits to be assessed has made feasible the introduction of a computerized technique for quick and reliable evaluation of quality checking of the kits. The proposed method makes use of a hyperbolic regression for the machine evaluation of the RIA measurements. The process can be used in its present form for the activity measurements of bound antigens in the system only. The calculator program does not use the data of the non-specific bounds (NBS value) and it contains procedures which can be solved by the given memory capacity of the calculator type proposed.

    Full Text Available Abstract Background The detection of Brucellae in tissue specimens using PCR assays is difficult because the amount of bacteria is usually low. Therefore, optimised DNA extraction methods are critical. The aim of this study was to assess the performance of commercial kits for the extraction of Brucella DNA. Methods Five kits were evaluated using clinical specimens: QIAamp™ DNA Mini Kit (QIAGEN, peqGold™ Tissue DNA Mini Kit (PeqLab, UltraClean™ Tissue and Cells DNA Isolation Kit (MoBio, DNA Isolation Kit for Cells and Tissues (Roche, and NucleoSpin™ Tissue (Macherey-Nagel. DNA yield was determined using a quantitative real-time PCR assay targeting IS711 that included an internal amplification control. Results Kits of QIAGEN and Roche provided the highest amount of DNA, Macherey-Nagel and Peqlab products were intermediate whereas MoBio yielded the lowest amount of DNA. Differences were significant (p Conclusions We observed differences in DNA yield as high as two orders of magnitude for some samples between the best and the worst DNA extraction kits and inhibition was observed occasionally. This indicates that DNA purification may be more relevant than expected when the amount of DNA in tissue is very low.

    Gastrointestinal stromal tumours (GISTs) represent a heterogeneous group of tumours of mesenchymal origin characterized by gain-of-function mutations in KIT or PDGFRA of the type III receptor tyrosine kinase family. Although mutations in either receptor are thought to drive an early oncogenic event through similar pathways, two previous studies reported the mutation-specific gene expression profiles. However, their further conclusions were rather discordant. To clarify the molecular characteristics of differentially expressed genes according to GIST receptor mutations, we combined microarray-based analysis with detailed functional annotations. Total RNA was isolated from 29 frozen gastric GISTs and processed for hybridization on GENECHIP ® HG-U133 Plus 2.0 microarrays (Affymetrix). KIT and PDGFRA were analyzed by sequencing, while related mRNA levels were analyzed by quantitative RT-PCR. Fifteen and eleven tumours possessed mutations in KIT and PDGFRA, respectively; no mutation was found in three tumours. Gene expression analysis identified no discriminative profiles associated with clinical or pathological parameters, even though expression of hundreds of genes differentiated tumour receptor mutation and expression status. Functional features of genes differentially expressed between the two groups of GISTs suggested alterations in angiogenesis and G-protein-related and calcium signalling. Our study has identified novel molecular elements likely to be involved in receptor-dependent GIST development and allowed confirmation of previously published results. These elements may be potential therapeutic targets and novel markers of KIT mutation status

  14. SeqKit: A Cross-Platform and Ultrafast Toolkit for FASTA/Q File Manipulation.

    Directory of Open Access Journals (Sweden)

    Wei Shen

    Full Text Available FASTA and FASTQ are basic and ubiquitous formats for storing nucleotide and protein sequences. Common manipulations of FASTA/Q file include converting, searching, filtering, deduplication, splitting, shuffling, and sampling. Existing tools only implement some of these manipulations, and not particularly efficiently, and some are only available for certain operating systems. Furthermore, the complicated installation process of required packages and running environments can render these programs less user friendly. This paper describes a cross-platform ultrafast comprehensive toolkit for FASTA/Q processing. SeqKit provides executable binary files for all major operating systems, including Windows, Linux, and Mac OSX, and can be directly used without any dependencies or pre-configurations. SeqKit demonstrates competitive performance in execution time and memory usage compared to similar tools. The efficiency and usability of SeqKit enable researchers to rapidly accomplish common FASTA/Q file manipulations. SeqKit is open source and available on Github at https://github.com/shenwei356/seqkit.

    Radiolabeled somatostatin analogs of peptide receptors targeting tumor cells have become a common practice in the diagnosis and treatment of certain types of cancer. The aim of this research was to develop the cold kit to be label with Ga-68 radionuclide for neuroendocrine tumor imaging. DOTATATE peptide for somatostatin receptor was formulated with NaOAc and ascorbic acid into lyophilized form. Radiochemical purity (RCP) of 68 Ga-DOTATATE labeled complex prepared from the cold kit was determined during storage period of 5 months and evaluated before clinical application to EANM guideline. The %RCP of the labeled peptide was more than 95% throughout period of storage with Ge-68 breakthrough less than 0.001%. The peptide content calculated from peak area of standard DOTATATE calibration curve using HPLC at uv 220 nm was found to be 15.3±4.62 μg. The specific activity of 68 Ga-DOTATATE, which depended on activities eluted from generator, was 34.7 - 52 MBq/nmol-peptide. The pH of the Ga-68 radiopharmaceutical kit after dilution with phosphate-buffered saline was 5.0 - 5.3. These results demonstrated that preparing of 68 Ga-DOTATATE radiopharmaceutical from lyophilized kit presented in this study was suitable and convenient method obtaining high radiochemical purity of short half-life Ga-68 radionuclide.

    Frégeau, Chantal J; Laurin, Nancy

    2015-05-01

    The Investigator® Quantiplex HYres kit was evaluated as a potential replacement for dual DNA quantification of casework samples. This kit was determined to be highly sensitive with a limit of quantification and limit of detection of 0.0049ng/μL and 0.0003ng/μL, respectively, for both human and male DNA, using full or half reaction volumes. It was also accurate in assessing the amount of male DNA present in 96 mock and actual casework male:female mixtures (various ratios) processed in this exercise. The close correlation between the male/human DNA ratios expressed in percentages derived from the Investigator® Quantiplex HYres quantification results and the male DNA proportion calculated in mixed AmpFlSTR® Profiler® Plus or AmpFlSTR® Identifiler® Plus profiles, using the Amelogenin Y peak and STR loci, allowed guidelines to be developed to facilitate decisions regarding when to submit samples to Y-STR rather than autosomal STR profiling. The internal control (IC) target was shown to be more sensitive to inhibitors compared to the human and male DNA targets included in the Investigator® Quantiplex HYres kit serving as a good quality assessor of DNA extracts. The new kit met our criteria of enhanced sensitivity, accuracy, consistency, reliability and robustness for casework DNA quantification. Crown Copyright © 2015. Published by Elsevier Ireland Ltd.

    The quinoline domain of OSI-930, a dual inhibitor of receptor tyrosine kinases (RTKs) c-Kit and KDR, was modified in an effort to further understand the SAR of OSI-930, and the binding site characteristics of c-Kit and KDR. A series of 16 compounds with heteroatom substituted pyridyl and phenyl ring systems was synthesized and evaluated against a panel of kinases including c-Kit and KDR. Aminopyridyl derivative 6 was found to be the most active member of the series with 91% and 57% inhibition of c-Kit at 10μM and 1μM, respectively and 88% and 50% inhibition of KDR at 10μM and 1μM, respectively. The target compounds were also tested for their ability to inhibit efflux of mitoxantrone through inhibition of ATP dependent ABCG2 pump. Nitropyridyl derivative 5 and o-nitrophenyl derivative 7 exhibited complete inhibition of the ABCG2 pump with IC(50) values of 13.67μM and 16.67μM, respectively. Copyright © 2011 Elsevier Ltd.

    High-risk type human papilloma virus (HPV) is the most important cause of cervical cancer. Recently, real-time polymerase chain reaction and reverse blot hybridization assay-based HPV DNA genotyping kits are developed. So, we compared the performances of different three HPV genotyping kits using different analytical principles and methods. Two hundred positive and 100 negative cervical swab specimens were used. DNA was extracted and all samples were tested by the MolecuTech REBA HPV-ID, Anyplex II HPV28 Detection, and HPVDNAChip. Direct sequencing was performed as a reference method for confirming high-risk HPV genotypes 16, 18, 45, 52, and 58. Although high-level agreement results were observed in negative samples, three kits showed decreased interassay agreement as screening setting in positive samples. Comparing the genotyping results, three assays showed acceptable sensitivity and specificity for the detection of HPV 16 and 18. Otherwise, various sensitivities showed in the detection of HPV 45, 52, and 58. The three assays had dissimilar performance of HPV screening capacity and exhibited moderate level of concordance in HPV genotyping. These discrepant results were unavoidable due to difference in type-specific analytical sensitivity and lack of standardization; therefore, we suggested that the efforts to standardization of HPV genotyping kits and adjusting analytical sensitivity would be important for the best clinical performance. © 2016 Wiley Periodicals, Inc.

    Brachytherapy continues to serve as an important and rapidly evolving tool in the management of cancer. Technological developments in the last two decades have dramatic impact on the safe practice of brachytherapy. A wide range of brachytherapy sources and equipment are available for new therapeutic possibilities. However, decision making with regard to new brachytherapy facilities are need based and depend on the patient load, socioeconomic status of the patients, and funds available with the institution. Remote afterloading equipments are fast replacing the Manual After Loading (MAL) systems. However, keeping in view the large number of patients, who can not afford expensive treatment, the utility of manual after loading system which is inexpensive, cannot be ignored

    Immobilized metal affinity chromatography (IMAC) technique is used for fast and reliable purification of histidine(His)-tagged recombinant proteins. The technique provides purification under native and denaturing conditions. The aim of this study is to evaluate three commercially available IMAC kits (Thermo Scientific, GE Healthcare and Qiagen) for the purification of a 6xHis-tagged recombinant CagA (cytotoxin-associated gene A) protein from IPTG-induced Escherichia coli BL21(DE3) culture. The kits were tested according to the manufacturer instructions and the protein was purified with only GE Healthcare and Qiagen kits under denaturing conditions. 1% (w/v) SDS was used as denaturing agent in PBS instead of extraction reagent of Thermo Scientific kit to lyse bacterial cells from 100ml culture. The 6xHis-tagged recombinant protein was purified by the three kits equally. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Piebaldism is a rare autosomal dominant disorder of melanocyte development, which is mostly caused by KIT gene. The key characteristics of piebaldism include localized poliosis, congenital leukoderma, and other variable manifestations. The previous study has illustrated that the homogeneous MC1R (a gene which is associated with the hair color variant (p.I120T coordinating with KIT mutation may lead to auburn hair color and piebaldism. In this study, we have investigated a Chinese family with piebaldism and auburn hair color; the mutation screening of KIT and MC1R genes identified that only a splicing mutation (c. 2484+1G>A of KIT gene cosegregated with the auburn hair color and piebaldism. The data of this study and others suggests that the KIT mutation may causes of the auburn hair color in the piebaldism patients.

    The CA 130 RIA kit was developed with the use of two monoclonal antibodies, 130 - 22 and 145 - 9. Laboratory performance was satisfactory for precision, reproducibility, recovery, and dilution. Measurement values with CA 130 kit were almost consistent with those with CA 125 kit. Favorable standard curves were attained with smaller concentrations and shorter incubation time of CA 130 kit than those with CA 125 kit. There was less prozone phenomenon. When defining a cut-off serum level of CA 130 as 35 U/ml, false-positive rate was 0 % for healthy men and 4 % for healthy women, suggesting the involvement of menstrual cycle. Positive rate for CA 130 was 65 % for malignant ovarian tumor, 48 % for lung cancer, and 47 % for endometriosis. (Namekawa, K.)

  11. OpenSatKit Enables Quick Startup for CubeSat Missions

    2017-01-01

    The software required to develop, integrate, and operate a spacecraft is substantial regardless of whether its a large or small satellite. Even getting started can be a monumental task. To solve this problem, NASAs Core Flight System (cFS), NASA's 42 spacecraft dynamics simulator, and Ball Aerospaces COSMOS ground system have been integrated together into a kit called OpenSatKit that provides a complete and open source software solution for starting a new satellite mission. Users can have a working system with flight software, dynamics simulation, and a ground command and control system up and running within hours.Every satellite mission requires three primary categories of software to function. The first is Flight Software (FSW) which provides the onboard control of the satellites and its payload(s). NASA's cFS provides a great platform for developing this software. Second, while developing a satellite on earth, it is necessary to simulate the satellites orbit, attitude, and actuators, to ensure that the systems that control these aspects will work correctly in the real environment. NASAs 42 simulator provides these functionalities. Finally, the ground has to be able to communicate with the satellite, monitor its performance and health, and display its data. Additionally, test scripts have to be written to verify the system on the ground. Ball Aerospace's COSMOS command and control system provides this functionality. Once the OpenSatKit is up and running, the next step is to customize the platform and get it running on the end target. Starting from a fully working system makes porting the cFS from Linux to a users platform much easier. An example Raspberry Pi target is included in the kit so users can gain experience working with a low cost hardware target. All users can benefit from OpenSatKit but the greatest impact and benefits will be to SmallSat missions with constrained budgets and small software teams. This paper describes OpenSatKits system design, the

    Majority of gastrointestinal stromal tumours (GISTs) are characterised by KIT-immunopositivity and the presence of KIT/platelet-derived growth factor receptor alpha (PDGFRA) activating mutations. Spectrum and frequency of KIT and PDGFRA mutations were investigated in 427 GISTs. Univariate and multivariate analysis of relapse-free survival (RFS) was conducted in relation to tumours' clinicopathologic features and genotype. Mutations were found in 351 (82.2%) cases, including 296 (69.3%) KIT and 55 (12.9%) PDGFRA isoforms. Univariate analysis revealed higher 5-year RFS rate in women (37.9%; P = 0.028) and in patients with gastric tumours (46.3%; P < 0.001). In addition a better 5-year RFS correlated with smaller tumour size ≤ 5 cm (62.7%; P < 0.001), tumours with mitotic index ≤ 5/50 high-power fields (60%; P < 0.001), and characterised by (very) low/moderate risk (70.2%; P = 0.006). Patients with GISTs bearing deletions encompassing KIT codons 557/558 had worse 5-year RFS rate (23.8%) than those with any other KIT exon 11 mutations (41.8%; P < 0.001) or deletions not involving codons 557/558 (33.3%; P = 0.007). Better 5-year RFS characterised patients with KIT exon 11 point mutations (50.7%) or duplications (40%). By multivariate analysis, tumours with PDGFRA mutations and KIT exon 11 point mutations/other than 557/558 deletions had lower risk of progression than with KIT exon 11 557/558 deletions (both Ps = 0.001). KIT/PDGFRA mutational status has prognostic significance for patients' outcome and may help in management of patients with GISTs.

    OSI-930, a potent thiophene inhibitor of the Kit, KDR, and platelet-derived growth factor receptor tyrosine kinases, was used to selectively inhibit tyrosine phosphorylation downstream of juxtamembrane mutant Kit in the mast cell leukemia line HMC-1. Inhibition of Kit kinase activity resulted in a rapid dephosphorylation of Kit and inhibition of the downstream signaling pathways. Attenuation of Ras-Raf-Erk (phospho-Erk, phospho-p38), phosphatidyl inositol-3' kinase (phospho-p85, phospho-Akt, phospho-S6), and signal transducers and activators of transcription signaling pathways (phospho-STAT3/5/6) were measured by affinity liquid chromatography tandem mass spectrometry, by immunoblot, and by tissue microarrays of fixed cell pellets. To more globally define additional components of Kit signaling temporally altered by kinase inhibition, a novel multiplex quantitative isobaric peptide labeling approach was used. This approach allowed clustering of proteins by temporal expression patterns. Kit kinase, which dephosphorylates rapidly upon kinase inhibition, was shown to regulate both Shp-1 and BDP-1 tyrosine phosphatases and the phosphatase-interacting protein PSTPIP2. Interactions with SH2 domain adapters [growth factor receptor binding protein 2 (Grb2), Cbl, Slp-76] and SH3 domain adapters (HS1, cortactin, CD2BP3) were attenuated by inhibition of Kit kinase activity. Functional crosstalk between Kit and the non-receptor tyrosine kinases Fes/Fps, Fer, Btk, and Syk was observed. Inhibition of Kit modulated phosphorylation-dependent interactions with pathways controlling focal adhesion (paxillin, leupaxin, p130CAS, FAK1, the Src family kinase Lyn, Wasp, Fhl-3, G25K, Ack-1, Nap1, SH3P12/ponsin) and septin-actin complexes (NEDD5, cdc11, actin). The combined use of isobaric protein quantitation and expression clustering, immunoblot, and tissue microarray strategies allowed temporal measurement signaling pathways modulated by mutant Kit inhibition in a model of mast cell

    Full Text Available Abstract Background Robust, programmatically accessible biomedical information services that syntactically and semantically interoperate with other resources are challenging to construct. Such systems require the adoption of common information models, data representations and terminology standards as well as documented application programming interfaces (APIs. The National Cancer Institute (NCI developed the cancer common ontologic representation environment (caCORE to provide the infrastructure necessary to achieve interoperability across the systems it develops or sponsors. The caCORE Software Development Kit (SDK was designed to provide developers both within and outside the NCI with the tools needed to construct such interoperable software systems. Results The caCORE SDK requires a Unified Modeling Language (UML tool to begin the development workflow with the construction of a domain information model in the form of a UML Class Diagram. Models are annotated with concepts and definitions from a description logic terminology source using the Semantic Connector component. The annotated model is registered in the Cancer Data Standards Repository (caDSR using the UML Loader component. System software is automatically generated using the Codegen component, which produces middleware that runs on an application server. The caCORE SDK was initially tested and validated using a seven-class UML model, and has been used to generate the caCORE production system, which includes models with dozens of classes. The deployed system supports access through object-oriented APIs with consistent syntax for retrieval of any type of data object across all classes in the original UML model. The caCORE SDK is currently being used by several development teams, including by participants in the cancer biomedical informatics grid (caBIG program, to create compatible data services. caBIG compatibility standards are based upon caCORE resources, and thus the caCORE SDK has

    In March 2015, Apple Inc announced ResearchKit, a novel open-source framework intended to help medical researchers to easily create apps for medical studies. With the announcement of this framework, Apple presented 5 apps built in a beta phase based on this framework. The objective of this study was to better understand decision making in patients with acute anterior cruciate ligament (ACL) ruptures. Here, we describe the development of a ResearchKit app for this study. A multilanguage observatory study was conducted. At first a suitable research topic, target groups, participating territories, and programming method were carefully identified. The ResearchKit framework was used to program the app. A secure server connection was realized via Secure Sockets Layer. A data storage and security concept separating personal information and study data was proposed. Furthermore, an efficient method to allow multilanguage support and distribute the app in many territories was presented. Ethical implications were considered and taken into account regarding privacy policies. An app study based on ResearchKit was developed without comprehensive iPhone Operating System (iOS) development experience. The Apple App Store is a major distribution channel causing significant download rates (>1.200/y) without active recruitment. Preliminary data analysis showed moderate dropout rates and a good quality of data. A total of 180 participants were currently enrolled with 107 actively participating and producing 424 completed surveys in 9 out of 24 months. ResearchKit is an easy-to-use framework and powerful tool to create medical studies. Advantages are the modular built, the extensive reach of iOS devices, and the convenient programming environment.

Total DNA from nasal washes corresponding to 30 asthmatic children was extracted using theQiagenQIAamp DNA and NorgenRNA/DNA Purification kits and analyzed via IlluminaMiSeq16S rRNA V4 ampliconsequencing. The Norgen samples included more sequence reads and OTUs per sample than the Qiagen samples, but OTU counts per sample varied proportionallybetween groups (r = 0.732.Microbial profiles varied slightly between sample pairs, but alpha- and beta-diversity indices (PCoAand clustering showed highsimilarity between Norgen and Qiagenmicrobiomes. Moreover, no significant differences in community structure (PERMANOVA and adonis tests and taxa proportions (Kruskal-Wallis test were observed betweenkits. Finally, aProcrustes analysis also showed low dissimilarity (M2 = 0.173; P< 0.001 between the PCoAs of the two DNA extraction kits. Contrary to what has been observed in previous studies comparing DNA extraction methods, our 16S NGS analysis of nasopharyngeal washes did not reveal significant differences in community composition or structure between kits. Our findingssuggest congruence between column-based chromatography kits and supportthe comparison of microbiomeprofilesacross nasopharyngeal metataxonomic studies.

    Bioinformatics skills have become essential for many research areas; however, the availability of qualified researchers is usually lower than the demand and training to increase the number of able bioinformaticians is an important task for the bioinformatics community. When conducting training or hands-on tutorials, the lack of control over the analysis tools and repositories often results in undesirable situations during training, as unavailable online tools or version conflicts may delay, complicate, or even prevent the successful completion of a training event. The eBioKit is a stand-alone educational platform that hosts numerous tools and databases for bioinformatics research and allows training to take place in a controlled environment. A key advantage of the eBioKit over other existing teaching solutions is that all the required software and databases are locally installed on the system, significantly reducing the dependence on the internet. Furthermore, the architecture of the eBioKit has demonstrated itself to be an excellent balance between portability and performance, not only making the eBioKit an exceptional educational tool but also providing small research groups with a platform to incorporate bioinformatics analysis in their research. As a result, the eBioKit has formed an integral part of training and research performed by a wide variety of universities and organizations such as the Pan African Bioinformatics Network (H3ABioNet) as part of the initiative Human Heredity and Health in Africa (H3Africa), the Southern Africa Network for Biosciences (SAnBio) initiative, the Biosciences eastern and central Africa (BecA) hub, and the International Glossina Genome Initiative.

    Introduction: During radiotherapy salivary glands of head and neck cancer patients are unavoidably co-irradiated, potentially resulting in life-long impairment. Recently we showed that transplantation of salisphere-derived c-Kit expressing cells can functionally regenerate irradiated salivary glands. This study aims to select a more potent subpopulation of c-Kit + cells, co-expressing stem cell markers and to investigate whether long-term tissue homeostasis is restored after stem cell transplantation. Methods and results: Salisphere derived c-Kit + cells that co-expressed CD24 and/or CD49f markers, were intra-glandularly injected into 15 Gy irradiated submandibular glands of mice. Particularly, c-Kit + /CD24 + /CD49f + cell transplanted mice improved saliva production (54.59 ± 11.1%) versus the irradiated control group (21.5 ± 8.7%). Increase in expression of cells with differentiated duct cell markers like, cytokeratins (CK8, 18, 7 and 14) indicated functional recovery of this compartment. Moreover, ductal stem cell marker expression like c-Kit, CD133, CD24 and CD49f reappeared after transplantation indicating long-term functional maintenance potential of the gland. Furthermore, a normalization of vascularization as indicated by CD31 expression and reduction of fibrosis was observed, indicative of normalization of the microenvironment. Conclusions: Our results show that stem cell transplantation not only rescues hypo-salivation, but also restores tissue homeostasis of the irradiated gland, necessary for long-term maintenance of adult tissue

    Mink are an important animal commodity group in Canada and excessive kit mortality represents a significant loss to production. National biosecurity standards have been developed for Canadian mink farms, but it is unclear how well these standards have been implemented as there are no studies correlating management practices of mink producers with causes of death in mink kits. To that end, we surveyed Ontario mink producers on their biosecurity and management practices and conducted almost 5660 post mortem examinations on found-dead, preweaned kits to characterize mink farm biosecurity practices and causes of death in preweaned kits. We found that very few biosecurity and management practices were uniformly used by producers, despite good awareness of appropriate practices. Use of personal protective equipment was implemented by fewer than 50% of respondents, while control of mink shed access, disinfection of feed containers after use, and use of a rodent control program were the only practices implemented by greater than 70% of respondents. Only 18% of producers reported regular use of antimicrobials in feed or water, although 91% stated they used antimicrobials for treatment of bacterial diseases on a regular basis. On post mortem examination, no gross abnormalities were noted in 71% of the kits, 45% were thought to be stillborn or aborted, 27% had some form of abnormal fluid distribution in the body, and 2% had a congenital malformation. A subset of 69 gastrointestinal tract samples was submitted for bacterial culture, of which 45 samples yielded sufficient growth. Most interesting was the identification of Salmonella enterica serovar Heidelberg in 11% of samples. The results of this study will provide a benchmark for Canadian mink producers and their veterinarians, defining the areas to which greater attention should be given to ensure more rigorous biosecurity practices are in place. Ultimately, these improvements in practices may contribute to increased mink

    Medical capabilities aboard the International Space Station (ISS) have been packaged to help astronaut crew medical officers (CMO) mitigate both urgent and non-urgent medical issues during their 6-month expeditions. Two ISS crewmembers are designated as CMOs for each 3-crewmember mission and are typically not physicians. In addition, the ISS may have communication gaps of up to 45 minutes during each orbit, necessitating medical equipment that can be reliably operated autonomously during flight. The retirement of the space shuttle combined with ten years of manned ISS expeditions led the Space Medicine Division at the NASA Johnson Space Center to reassess the current ISS Medical Kit System. This reassessment led to the system being streamlined to meet future logistical considerations with current Russian space vehicles and future NASA/commercial space vehicle systems. Methods The JSC Space Medicine Division coordinated the development of requirements, fabrication of prototypes, and conducted usability testing for the new ISS Medical Kit System in concert with implementing updated versions of the ISS Medical Check List and associated in-flight software applications. The teams constructed a medical kit system with the flexibility for use on the ISS, and resupply on the Russian Progress space vehicle and future NASA/commercial space vehicles. Results Prototype systems were developed, reviewed, and tested for implementation. Completion of Preliminary and Critical Design Reviews resulted in a streamlined ISS Medical Kit System that is being used for training by ISS crews starting with Expedition 27 (June 2011). Conclusions The team will present the process for designing, developing, , implementing, and training with this new ISS Medical Kit System.

    Imatinib mesylate is used in targeted therapy of cancer to inhibit type III tyrosine kinase receptors, such as KIT and platelet-derived growth factor receptors (PDGFRs). Expression of KIT in uveal melanoma (UM) suggests that this receptor may be the target of imatinib mesylate therapy. However, phase II multicenter clinical studies have shown no effect of imatinib mesylate in patients with unresectable liver metastases of UM. We therefore investigated which molecular mechanisms promote imatinib mesylate-resistance in metastatic UM. Expression of KIT, stem cell factor (SCF), PDGFRα and PDGFRβ, was analyzed by RT-PCR, immunostaining, and Western blot in twenty-four samples of UM liver metastases, as well as UM primary tumor and metastatic cell lines. Soluble SCF was quantified in UM cell lines using enzyme-linked immunosorbent assay. Cell viability of UM cell lines treated with imatinib mesylate and grown in SCF-supplemented medium or in microvascular endothelial cells-conditioned medium was studied by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assays. UM liver metastases and cell lines expressed KIT and SCF, but not the PDGFRs. Ninety-five percent of liver metastases expressed KIT at the protein level, but PDGFRs were not detected in these samples. Imatinib mesylate reduced the viability of UM metastatic cell lines in a concentration-dependent manner, but an increased resistance to this drug was observed when cells were incubated in SCF-supplemented or microvascular endothelial cells-conditioned medium. This study provides evidence that tumor microenvironment cytokines such as SCF may promote resistance to imatinib mesylate in metastatic UM.

    Full Text Available Drinking of arsenic (As contaminated ground water is threatening the health of millions of peoples of Bangladesh. The screening of tube wells (TWs water for As in Bangladesh and elsewhere in the world is done by As testing kits. The results of water-As by these kits are semi-quantitative and personal error is high. An attempt has been undertaken for quantitative determination of water-As by MITech arsenic test kit by applying quantitative image analysis method from the digital picture of the colored test paper of the kit. In the quantitative image analysis method, the color of the test paper is numerically determined by color difference between the test water samples with the standard color chart which is calculated from Lab (lightness (L, color opponent green-red (a, and color opponent blue-yellow (b values. TWs water-As concentrations in Bashailbogh village, Munshiganj, Bangladesh were determined by using MITech arsenic field test kit by conventional method, quantitative image analysis method and inductively coupled plasma mass spectrometer (ICP-MS method. The water-As by the quantitative image method gave quite close results (R2 = 0.998 to those obtained with ICP-MS method at concentration up to 50 µg As L-1. The water-As concentration more than 50 µg As L-1 by this method was underestimated. Hence, the developed method may be used for quantitative analysis of water-As in the range of 0–50 µg As L-1 for water-As screening program. [Fundam Appl Agric 2018; 3(1.000: 340-346

    We demonstrate that SCF-KIT signaling induces synthesis and secretion of endothelin-3 (ET3) in human umbilical vein endothelial cells and melanoma cells in vitro, gastrointestinal stromal tumors, human sun-exposed skin, and myenteric plexus of human colon post-fasting in vivo. This is the first report of a physiological mechanism of ET3 induction. Integrating our finding with supporting data from literature leads us to discover a previously unreported pathway of nitric oxide (NO) generation derived from physiological endothelial NO synthase (eNOS) or neuronal NOS (nNOS) activation (referred to as the KIT-ET3-NO pathway). It involves: (1) SCF-expressing cells communicate with neighboring KIT-expressing cells directly or indirectly (cleaved soluble SCF). (2) SCF-KIT signaling induces timely local ET3 synthesis and secretion. (3) ET3 binds to ETBR on both sides of intercellular space. (4) ET3-binding-initiated-ETBR activation increases cytosolic Ca2+, activates cell-specific eNOS or nNOS. (5) Temporally- and spatially-precise NO generation. NO diffuses into neighboring cells, thus acts in both SCF- and KIT-expressing cells. (6) NO modulates diverse cell-specific functions by NO/cGMP pathway, controlling transcriptional factors, or other mechanisms. We demonstrate the critical physiological role of the KIT-ET3-NO pathway in fulfilling high demand (exceeding basal level) of endothelium-dependent NO generation for coping with atherosclerosis, pregnancy, and aging. The KIT-ET3-NO pathway most likely also play critical roles in other cell functions that involve dual requirement of SCF-KIT signaling and NO. New strategies (e.g. enhancing the KIT-ET3-NO pathway) to harness the benefit of endogenous eNOS and nNOS activation and precise NO generation for correcting pathophysiology and restoring functions warrant investigation.

CD3+ T-cells and c-kit overexpression revealed a positive correlation with VEGF (r = 0.503, P < 0.0001; r = 0.284, P = 0.023 for CD3 and c-kit, resp. and CD31 (r = 0.654, P < 0.0001; r = 0.365, P = 0.003 for CD3 and c-kit, resp.. A significant association (P = 0.039 and a positive correlation (r = 0.263, P = 0.039 between CD3 and c-kit were also observed. High CD3/VEGF, c-kit/VEGF, and CD3/c-kit tumors were associated with elevated grade of malignancy (P < 0.0001 for all groups, presence of intravascular emboli (P < 0.0001 for CD3/VEGF and CD3/c-kit; P = 0.002 for c-kit/VEGF, and presence of lymph node metastasis (P < 0.0001 for all groups. Tumors with high CD3/VEGF (P = 0.006, c-kit/VEGF (P < 0.0001, and CD3/c-kit (P = 0.002 were associated with poor prognosis. Interestingly high c-kit/VEGF tumors retained their significance by multivariate analysis arising as independent prognostic factor.

  5. Development of kits for radioimmunometric assays for tumour markers. Final report of a co-ordinated research project 1997-2001

    International Nuclear Information System (INIS)

    2002-08-01

    Many tumour marker assays have been reported over the years and their role is well recognized and acknowledged in the follow-up of known cancer cases. However, their true potential for use in primary diagnosis or screening of high risk groups is still to be fully realized due to the need to achieve better specificity. Among the various tumour markers, the one for prostate cancer - prostate specific antigen (PSA) - appears to have better specificity, coming close to a tumour specific antigen. Prostate cancer is a commonly encountered cancer in men, and can be effectively treated if detected early. PSA levels in serum appear to provide good correlation with tumour burden. Estimation of free PSA in serum is reported to further improve the diagnosis. In several developed countries routine screening of men above 50 years of age for prostate cancer using serum PSA as marker is recommended. Radioimmunometric assay techniques offer themselves as attractive candidates for measurement of tumour markers. They are robust, economical and didactic, thus eminently suitable for technology transfer, training and teaching. Preparation of primary reagents is relatively easy. The methodology is flexible. As a result of co-operation projects of the IAEA, many developing Member States have built up indigenous capabilities to perform radioimmunometric assays, which can be extended to development of kits for tumour marker assays. Considering the need for indigenous development of capabilities to produce reliable kits for radioimmunometric assays for PSA, in 1997 the IAEA initiated a Co-ordinated Research Project (CRP) on Development of Kits for Radioimmunometric Assays for Tumour Markers. Even though the focus of the project was PSA, it was expected that the expertise to be gained by the participants would also help them undertake development of kits for other tumour markers, essentially using the same methodology. Ten laboratories from Europe, Asia, Africa and the Americas participated

    Full Text Available Objective. 25-hydroxyvitamin D2/D3 (25-OHD2/D3 determination is a reliable biomarker for vitamin D status. Liquid chromatography-tandem mass spectrometry was recently proposed as a reference method for vitamin D status evaluation. The aim of this work is to compare two commercial kits (Chromsystems and PerkinElmer for 25-OHD2/D3 determination by our entry level LC-MS/MS. Design and Methods. Chromsystems kit adds an online trap column to an HPLC column and provides atmospheric pressure chemical ionization, isotopically labeled internal standard, and 4 calibrator points. PerkinElmer kit uses a solvent extraction and protein precipitation method. This kit can be used with or without derivatization with, respectively, electrospray and atmospheric pressure chemical ionization. For each analyte, there are isotopically labeled internal standards and 7 deuterated calibrator points. Results. Performance characteristics are acceptable for both methods. Mean bias between methods calculated on 70 samples was 1.9 ng/mL. Linear regression analysis gave an of 0.94. 25-OHD2 is detectable only with PerkinElmer kit in derivatized assay option. Conclusion. Both methods are suitable for routine. Chromsystems kit minimizes manual sample preparation, requiring only protein precipitation, but, with our system, 25-OHD2 is not detectable. PerkinElmer kit without derivatization does not guarantee acceptable performance with our LC-MS/MS system, as sample is not purified online. Derivatization provides sufficient sensitivity for 25-OHD2 detection.

    Autocrine activation of c-kit (KIT receptor tyrosine kinase) has been postulated to be a potent oncogenic driver in small cell lung cancer, neuroblastoma (NB), and poorly differentiated colorectal carcinoma (CRC). Although targeted therapy involving tyrosine kinase inhibitors (TKIs) such as imatinib mesylate is highly effective for gastrointestinal stromal tumor carrying V560G c-kit mutation, it does not show much potential for targeting wild-type KIT (WT-KIT). Our study demonstrates the role of stem cell factor (SCF)-based toxin conjugates for targeting WT-KIT-overexpressing malignancies such as NBs and CRCs. We constructed SCF-based recombinant bacterial toxins by genetically fusing mutated form of natural ligand SCF to receptor binding deficient forms of Diphtheria toxin (DT) or Pseudomonas exotoxin A (ETA') and evaluated their efficacy in vitro. Efficient targeting was achieved in all receptor-positive neuroblastoma (IMR-32 and SHSY5Y) and colon cancer cell lines (COLO 320DM, HCT 116, and DLD-1) but not in receptor-negative breast carcinoma cell line (MCF-7) thereby proving specificity. While dose- and time-dependent cytotoxicity was observed in both neuroblastoma cell lines, COLO 320DM and HCT 116 cells, only an anti-proliferative effect was observed in DLD-1 cells. We prove that these novel targeting agents have promising potential as KIT receptor tyrosine kinase targeting system.

    Bacillus spp. include human pathogens such as Bacillus anthracis, the causative agent of anthrax and a biothreat agent. Bacillus spp. form spores that are physically highly resistant and may remain active over sample handling. We tested four commercial DNA extraction kits (QIAamp DNA Mini Kit, RTP Pathogen Kit, ZR Fungal/Bacterial DNA MiniPrep, and genesig Easy DNA/RNA Extraction kit) for sample inactivation and DNA recovery from two powders (icing sugar and potato flour) spiked with Bacillus thuringiensis spores. The DNA was analysed using a B. thuringiensis-specific real-time PCR assay. The detection limit was 3×10(1)CFU of spiked B. thuringiensis spores with the QIAamp DNA Mini, RTP Pathogen, and genesig Easy DNA/RNA Extraction kits, and 3×10(3)CFU with the ZR Fungal/Bacterial DNA MiniPrep kit. The results showed that manual extraction kits are effective and safe for fast and easy DNA extraction from powder samples even in field conditions. Adding a DNA filtration step to the extraction protocol ensures the removal of Bacillus spp. spores from DNA samples without affecting sensitivity. Copyright © 2016 Elsevier B.V.

    Hepatocellular carcinoma (HCC) is a big problem in China where the Hepatitis B (HBV) infection patients are near to 120 million. Early screening and diagnosis is the key to reduce the incidence and mortality of HCC. Serum AFP detection is the main methods for diagnosis, recurrent monitoring and therapeutic evaluation of primary HCC. Hepatitis patients should detect the AFP at least once every six months to help early diagnosis of HCC. Unfortunately, most hepatitis and other liver disease patients do not test their AFP regularly. Therefore, a rapid, convenient detect kit for AFP is necessary for the hepatitis patients to test AFP at home by themselves. It will be very helpful to the HCC early screening and early diagnosis. We screened 859 individuals who were HBsAg positive and had high risk of HCC in Qidong by using two different kits, AFP one-step rapid detection kit (Shanghai Outdo Biotech) and AFP Diagnostics ELISA kit (Zhengzhou Autobio Diagnostics), and compared the results. As a result, the positive accordance rate and the negative accordance rate of AFP one-step rapid detection kit and the Autobio ELISA kit were 95.65% (22/23) and 99.40% (831/836), respectively. The total diagnose accordance rate reached up to 99.30% (853/859). The screening results showed a high accordance rate of two methods. It is so meaningful to achieve home-test and improve HCC early screening and diagnosis by using AFP one-step rapid detection kit.

    To investigate the relationship between secondary mutations of c-kit/PDGFRα resistance to imatinib mesylate and the efficacy of sunitinib in patients with gastrointestinal stromal tumor (GIST). Five pairs specimens were collected before and after imatinib mesylate resistance. DNA for molecular genetic investigation was extracted from formalin-fixed, paraffin-embedded tissues. Mutational analysis was performed by using PCR and direct sequencing. Five pairs of specimens were collected before and after imatinib mesylate resistance from 5 GIST patients. C-kit exon 11 mutations were detected in 3 patients, which were all acquired mutations, including c-kit exon 13 V654A, c-kit exon 13 V654E and c-kit exon 17 N822K, after imatinib mesylate resistance. Furthermore, after sunitinib treatment, 3 patients had stable disease and progression free survival (PFS) were 3.5 months, 4.4 months and 3.8 months, respectively. C-kit exon 9 mutations were detected in 2 patients with no acquired mutations after imatinib mesylate resistance. And the both had partial response from sunitinib, following with 13.1 months and 12.0 months PFS respectively. The c-kit/PDGFRα genotypes after imatinib mesylate resistance may both relate to primary mutations and efficacy of sunitinib treatment.

    KIT activity is crucial for gastrointestinal stromal tumors (GIST). Imatinib (IMA) and sunitinib (SUN) are very effective KIT-inhibitors in patients with advanced GIST but have no curative potential. We evaluated the efficacy of the novel HSP90 inhibitor IPI-493 alone, or in combination with IMA or SUN in GIST xenografts with KIT mutations. Nude mice (n = 98) were grafted bilaterally with human GIST carrying KIT exon 11 (GIST-PSW), KIT exon 9 (GIST-BOE), or double, KIT imatinib-sensitive exon 11 and imatinib-resistant exon 17 mutations (GIST-48). Mice were divided into six treatment groups and dosed orally for 15 days as follows: (i) control group, sterile water; (ii) IMA alone; (iii) SUN alone; (iv) IPI-493 alone; (v) IPI-493+IMA; and (vi) IPI-493+SUN. Treatment with IPI-493 resulted in tumor growth stabilization, variable proliferation arrest, induction of apoptosis and necrosis, and downregulation of KIT and its signaling cascade, especially in the GIST-BOE model. Significant reduction of vessel density was observed with IPI-493 treatment, and was equal to SUN treatment in GIST-PSW and GIST-BOE xenografts. IPI-493 treatment effects were enhanced in combination with TKIs, especially with IPI-493+SUN. In our hands, IPI-493 showed dose-dependent liver damages. When administered as a single agent in a xenograft model, the HSP90 inhibitor IPI-493 has consistent antitumor activity and induces KIT downregulation in GISTs with heterogeneous KIT mutations. IPI-493 synergizes with TKIs that are commonly used for the treatment of advanced or IMA-resistant GIST. The antitumor response of IPI-493 is particularly enhanced in combination with SUN. ©2011 AACR.

  13. Mutation of the KIT (mast/stem cell growth factor receptor) protooncogene in human piebaldism

    1991-10-01

    Piebaldism is an autosomal dominant genetic disorder characterized by congenital patches of skin and hair from which melanocytes are completely absent. A similar disorder of mouse, dominant white spotting (W), results from mutations of the c-Kit protooncogene, which encodes the receptor for mast/stem cell growth factor. The authors identified a KIT gene mutation in a proband with classic autosomal dominant piebaldism. This mutation results in a Gly {yields} Arg substitution at codon 664, within the tyrosine kinase domain. This substitution was not seen in any normal individuals and was completely linked to the piebald phenotype in the proband's family. Piebaldism in this family thus appears to be the human homologue to dominant white spotting (W) of the mouse.

    Six strains of Neisseria cinerea were tested in BACTEC Neisseria Differentiation kits (Johnston Laboratories, Inc., Towson, Md.), and all yielded positive glucose growth indices and negative maltose and fructose growth indices. These results were similar to those achieved with Neisseria gonorrhoeae. However, most of the N. cinerea isolates tested yielded 3-h glucose growth indices that were lower than those obtained with gonococci. 14 C-labeled gas was produced significantly faster by N. gonorrhoeae than by N. cinerea. Additional studies suggested that the 14 C-labeled gas produced by N. cinerea was carbon dioxide. N. cinerea strains were similar to Branhamella catarrhalis strains because both species failed to produce detectable acid from glucose, maltose, sucrose, fructose, and lactose in cysteine-tryptic agar media. However, in contrast to N. cinerea strains, B. catarrhalis strains did not metabolize glucose in BACTEC Neisseria Differentiation kits

    A procedure based on a fast technique of LAL individual kits has been devised to control bacterial endotoxins in radiodiagnosis agents (RDA): HEMTEC, DEIDA, PPI, AMD, GHCa, RENTEC, DMSA, MAA, TSC, HERTEC, DTPA, BRATEC and EDTMP as well as in radioisotopes I-131 and Tc99m. The procedures begins with the determination of the following values, injection volume (IV), endotoxin limits (EL), maximum valid dilution (MVD), total mass (TM), reconstitution volume (RV), concentration (mg/ml), and final dilution (FD). Subsequently, a procedure is carried out to conduct an 'in vitro' control of the radiodiagnosis agents and radioisotopes with LAL individual kits; the procedures includes: reconstitution of the sample to be controlled, dilution, inoculation of the diluted sample in LAL tubes and incubation at 37 o C for an hour. Finally, results are interpreted through the observation of gel formation or not in LAL tubes

    Full Text Available The reliability and availability of FOODLABfat system for determining acid value (AV and peroxide value (POV were assessed during the hydrolytic rancidification and lipid oxidation of edible oils. This reagent kit based on spectrophotometry was compared to the official methods (ISO 660 and 3960 protocols based on manual titration employing the standard mixture for the simulated oxidation models and edible oils during the thermally induced oxidation at 180°C. The linear regression line of standard mixture and the significant difference of thermally oxidized time course study determined between them showed high correlations (R2=0.998 and p<0.05 in both AVs and POVs. Considering ISO protocols with a probability of human error in manual titration, the rapidness and simplicity of the reagent kit based on spectrophotometry make it a promising alternative to monitor the lipid oxidation of edible oils and lipid-containing foods.

    1994-01-01

    A method of quantitating stannous ion [Sn(II)] suitable for radiopharmaceutical kits, based on indirect iodometric titration, is described. The method is based on the oxidation of Sn(II) using a known excess of iodine and the excess unreacted iodine determined using thiosulphate by potentiometric titration. The titration cell is a beaker and the titrations are done conveniently under air using an autotitrator in approx. 4 min. The method is accurate and is linear in the range of approx. 10 μg to approx. 6 mg of Sn(II). Several radiopharmaceutical kits were analysed for their Sn(II) content using the method including those containing antibodies or other proteins. The studies indicate that the procedure is rapid, simple and accurate for routine quantitative estimation of Sn(II) in radiopharmaceutical preparations during development, manufacture and storage.

    Full Text Available A kit based on an enzyme immunoassay, EIE-Recombinant-Chagas-Biomanguinhos, developed by the Oswaldo Cruz Foundation, was evaluated for the serodiagnosis of chronic Chagas disease. Evaluation was performed with 368 serum samples collected from individuals living in an endemic area for Chagas disease: 131 patients in the chronic phase with confirmed clinical, epidemiological, and serological diagnosis (indirect immunofluorescence, indirect hemagglutination or enzyme-linked immunosorbent assay and 237 nonchagasic seronegative individuals were considered negative control. The EIE-Recombinant-Chagas-Biomanguinhos kit showed high sensitivity, 100% (CI 95%: 96.4-100% and high specificity, 100% (CI 95%: 98-100%. The data obtained were in full agreement with clinical and conventional serology data. In addition, no cross-reaction was observed with sera from patients with cutaneous (n=14 and visceral (n=3 leishmaniasis. However, when these sera were tested by conventional serological assays for Chagas disease, cross-reactions were detected in 14.3% and 33.3% of the patients with cutaneous and visceral leishmaniasis, respectively. No cross-reactions were observed when sera from nonchagasic seronegative patients bearing other infectious disease (syphilis, n=8; HTLV, n=8; HCV, n=7 and HBV, n=12 were tested. In addition, sera of patients with inconclusive results for Chagas disease by conventional serology showed results in agreement with clinical evaluation, when tested by the kit. These results are relevant and indicate that the refered kit provides a safe immunodiagnosis of Chagas disease and could be used in blood bank screening.

    2015-01-01

    Poor quality lighting not only impedes astronomy research, but creates safety issues, affects human circadian sensitivities, disrupts ecosystems, and wastes more than a few billion dollars/year of energy in the USA alone. The United Nations-sanctioned the International Year of Light in 2015 (IYL2015) is providing an opportunity to increase public awareness of dark skies preservation, quality lighting and energy conservation. The Education and Public Outreach (EPO) group at the National Optical Astronomy Observatory (NOAO) has received a small grant through the International Astronomical Union (IAU) to produce official 'Quality Lighting Teaching Kits' for the IYL2015 cornerstone theme, 'Cosmic Light'. These kits will emphasize the use of proper optical design in achieving quality lighting that promotes both energy efficiency and energy conservation of an endangered natural resource, our dark skies. The concepts and practice of 'quality lighting' will be explored through demonstrations, hands-on/minds-on activities, formative assessment probes, and engineering design projects that explore basic principles of optics and the physics of light. The impact of the kits will be amplified by providing professional development using tutorial videos created at NOAO and conducting question and answer sessions via Google+ Hangouts for the outreach volunteers. The quality lighting education program will leverage NOAO EPO's work in the last ten years on lighting and optics education (e.g., the IAU 'Dark Skies Africa', APS 'Dark Skies Yuma' and 'Hands-On Optics' programs). NOAO's partners are CIE (International Commission on Illumination), IDA (International Dark-Sky Association) and SPIE (International Society for Optics and Photonics), as well as the IAU Office of Astronomy for Development, Galileo Teacher Training Program, Universe Awareness, and Global Hands-on Universe. Their networks will disseminate the program and kits to formal and informal audiences worldwide. The impact

    2017-10-05

    Various organophosphorus compounds (OP), primarily the nerve agent VX and other V-agents, are highly toxic to humans after skin exposure. Percutaneous exposure by such OP results in a delayed onset of toxic signs which enables the initiation of specific countermeasures if contamination is detected rapidly. Presently available mobile detection systems can hardly detect skin exposure by low volatile OP. In order to fill this gap an OP skin disclosure kit was developed which should fulfill different requirements, i.e. a high sensitivity, coverage of human toxic OP, easy handling, rapid results, small dimension and weight. The kit includes a cotton swab to sample skin, human AChE as target and chemicals for a color reaction based on the Ellman assay which is recorded by visual inspection. OP is dissolved from the sampler in a test tube filled with phosphate buffer (0.1M, pH 7.4) and incubated with lyophilized human AChE for 1min. The reaction with acetylthiocholine and 5,5'-dithio-bis-2-nitrobenzoic acid (1min) results in a rich yellow color in the absence of OP and in contrast, in transparent or pale yellow buffer in the presence of OP. At the recommended conditions, the limit of detection is 100ng VX and Russian VX and 50ng Chinese VX on plain surface and 200ng VX on rat skin. With activated pesticides, paraoxon and malaoxon, a concentration of ∼10μg can be detected on plain surface. The ready-to-use kit has a weight of 16g and a size of 10×12×1cm. In the end, this kit has the potential to fill a major gap and to enable timely detection of OP skin exposure and initiation of life-saving countermeasures. Copyright © 2017 Elsevier B.V.

    Mauro Romero L. Passos

    Full Text Available Diagnosis of vaginal discharge is frequently performed in an empirical way, leading to inadequate treatment. This study tested the accuracy of a self-collection kit for microbiological study of the vaginal content. One hundred and forty-two women of Family Health Program units in Niterói and Piraí cities were enrolled in order to have their vaginal content studied. A brief explanation and a self-collection kit were provided in order to sample the vaginal content. The self-collection kit was composed of one empty plastic tube, two glass slides, a long handle cytobrush, an identification card and guideline notes. The vaginal sample was applied on the glass slides by the women and stained by Gram technique. A second sampling was done by the medical personnel. The microbiological diagnosis in a blinded analysis was made under optical microscopy. A validation diagnosis test was done taking the medical collection results as a gold standard. A total of 106 women had followed the protocol and were included in the study. Microbiological analysis was unsatisfactory in 12 cases (6 cases of self-collection material and 6 cases of medical collection. The microbiological analyses in the self-collection and in the medical collection material were respectively: bacterial vaginosis in 21.7% and 17.9%, non bacillar flora in 10.3% and 11.3%, vaginal trichomoniasis in 5.66% and 5.6%, candidiasis in 3.78% and 2.8% and a normal microbiota in 52.8% and 56.6%. The Kappa coefficient suggested a "very good correlation" of the microbiological results between the two methods of collection (K=0.7945. The self-collection kit provides samples for microbiological analysis of the vaginal microbiota as good as medical collection.

    Cancer biomarker studies often require nucleic acid extraction from limited amounts of formalin-fixed, paraffin-embedded (FFPE) tissues, such as histologic sections or needle cores. A major challenge is low quantity and quality of extracted nucleic acids, which can limit our ability to perform genetic analyses, and have a significant influence on overall study design. This study was aimed at identifying the most reliable and reproducible method of obtaining sufficient high-quality nucleic acids from FFPE tissues. We compared the yield and quality of nucleic acids from 0.6-mm FFPE prostate tissue cores across 16 DNA and RNA extraction protocols, using 14 commercially available kits. Nucleic acid yield was determined by fluorometry, and quality was determined by spectrophotometry. All protocols yielded nucleic acids in quantities that are compatible with downstream molecular applications. However, the protocols varied widely in the quality of the extracted RNA and DNA. Four RNA and five DNA extraction protocols, including protocols from two kits for dual-extraction of RNA and DNA from the same tissue source, were prioritized for further quality assessment based on the yield and purity of their products. Specifically, their compatibility with downstream reactions was assessed using both NanoString nCounter gene expression assays and reverse-transcriptase real-time PCR for RNA, and methylation-specific PCR assays for DNA. The kit deemed most suitable for FFPE tissue was the AllPrep kit by Qiagen because of its yield, quality, and ability to purify both RNA and DNA from the same sample, which would be advantageous in biomarker studies.

    The Dominant White locus (W) in the domestic cat demonstrates pleiotropic effects exhibiting complete penetrance for absence of coat pigmentation and incomplete penetrance for deafness and iris hypopigmentation. We performed linkage analysis using a pedigree segregating White to identify KIT (Chr. B1) as the feline W locus. Segregation and sequence analysis of the KIT gene in two pedigrees (P1 and P2) revealed the remarkable retrotransposition and evolution of a feline endogenous retrovirus (FERV1) as responsible for two distinct phenotypes of the W locus, Dominant White, and white spotting. A full-length (7125 bp) FERV1 element is associated with white spotting, whereas a FERV1 long terminal repeat (LTR) is associated with all Dominant White individuals. For purposes of statistical analysis, the alternatives of wild-type sequence, FERV1 element, and LTR-only define a triallelic marker. Taking into account pedigree relationships, deafness is genetically linked and associated with this marker; estimated P values for association are in the range of 0.007 to 0.10. The retrotransposition interrupts a DNAase I hypersensitive site in KIT intron 1 that is highly conserved across mammals and was previously demonstrated to regulate temporal and tissue-specific expression of KIT in murine hematopoietic and melanocytic cells. A large-population genetic survey of cats (n = 270), representing 30 cat breeds, supports our findings and demonstrates statistical significance of the FERV1 LTR and full-length element with Dominant White/blue iris (P < 0.0001) and white spotting (P < 0.0001), respectively.

    Development agencies enthusiastically promote micro-drip irrigation as an affordable water and labor-saving device, yet most farmers stop using it as soon as development projects end. This article analyzes why farmers engage in projects promoting drip irrigation kits, even though they appear not to be interested in their water and labor-saving attributes. We combine practice-based theories of innovation with insights from the anthropology of development to explain that in development project ...

    The Phadebact Streptococcus Test and the Streptex Test kits were evaluated for grouping streptococci directly from blood cultures. Pellets of bacteria obtained from centrifuged samples of positive blood cultures were inoculated into Todd-Hewitt broth for 2- and 4-h Phadebact tests and into pronase for Streptex tests. Hemolysis was determined after pipetting a portion of each pellet into cuts made in blood agar plates incubated anaerobically for 2 to 6 h. Serological groups were also determine...

    Summary In crisis situations, such as transportation catastrophes, terrorist attacks or contamination with chemical warfare agents, it is crucial to properly organize and sensibly conduct rescue operations. Among chemical warfare agents, the most toxic ones are the derivatives of organophosphorus compounds. An individual auto-injector kit ?IZAS-05? contains auto-injectors, which are devices designed for intramuscular administration of drugs in self-aid or buddy-aid on the battlefield. This pa...

    Growth performance and metabolism were investigated in mink kits (n = 210) exposed to the same dietary treatment as their dams (n = 30), i.e. high (HP; 61% of metabolisable energy, ME), medium (MP; 48% of ME) or low (LP; 30% of ME) protein supply, from birth until 10 weeks of age. The kits were weighed weekly, and were measured by means of balance experiment and indirect calorimetry, in weeks eight and nine post-partum (p.p.). At weaning (seven weeks p.p.) and 10 weeks p.p. one kit per litter was killed and blood, liver and kidneys were collected. Plasma amino acid profiles, and hepatic abundance of mRNA for phosphoenolpyruvate carboxykinase (PEPCK), fructose 1,6-biphosphatase, pyruvate kinase and glucose-6-phosphatase (G-6-Pase) by q-PCR, were determined. There were no differences in live weights among kits the first four weeks of life when kits solely consumed milk, but male LP kits were the heaviest. After transition to solid feed MP kits weighed most at nine weeks of age (p < 0.05). At eight weeks of age, the kits fed the LP diet retained less (p < 0.05) N than HP and MP kits. Heat production did not differ among kits, although protein oxidation was higher (p < 0.001) in HP kits than in LP kits. Kits fed the LP diet had lower (p < 0.05) plasma concentrations of lysine, methionine and leucine than MP kits. Dietary treatment was not reflected in the relative abundance of any of the studied mRNAs, but kits had significantly lower abundance of all studied mRNA than their dams, ranging from 83% less PEPCK abundance to 40% less for G-6-Pase. The kidney mass was smallest (p < 0.01) in kits fed the LP diet, and liver masses were largest (p < 0.001) in HP kits. The results indicate that the LP diet did not meet the protein requirements for mink kits in the transition period from milk to solid feed. The capacity to regulate the rate of gluconeogenesis was even more limited in young mink kits than in adult dams. However, young mink kits can regulate protein oxidation in
