    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

    2001-05-31

    Western Research Institute (WRI) is commercializing Diesel Dog Portable Soil Test Kits for performing analysis of fuel-contaminated soils in the field. The technology consists of a method developed by WRI (U.S. Patents 5,561,065 and 5,976,883) and hardware developed by WRI that allows the method to be performed in the field (patent pending). The method is very simple and does not require the use of highly toxic reagents. The aromatic components in a soil extract are measured by absorption at 254 nm with a field-portable photometer. WRI added significant value to the technology by taking the method through the American Society for Testing and Materials (ASTM) approval and validation processes. The method is designated ASTM Method D-5831-96, Standard Test Method for Screening Fuels in Soils. This ASTM designation allows the method to be used for federal compliance activities. In FY 99, twenty-five preproduction kits were successfully constructed in cooperation with CF Electronics, Inc., of Laramie, Wyoming. The kit components work well and the kits are fully operational. In the calendar year 2000, kits were provided to the following entities who agreed to participate as FY 99 and FY 00 JSR (Jointly Sponsored Research) cosponsors and use the kits as opportunities arose for field site work: Wyoming Department of Environmental Quality (DEQ) (3 units), F.E. Warren Air Force Base, Gradient Corporation, The Johnson Company (2 units), IT Corporation (2 units), TRC Environmental Corporation, Stone Environmental, ENSR, Action Environmental, Laco Associates, Barenco, Brown and Caldwell, Dames and Moore Lebron LLP, Phillips Petroleum, GeoSyntek, and the State of New Mexico. By early 2001, ten kits had been returned to WRI following the six-month evaluation period. On return, the components of all ten kits were fully functional. The kits were upgraded with circuit modifications, new polyethylene foam inserts, and updated instruction manuals.

    During mitosis, chromosomes are attached to the mitotic spindle via large protein complexes called kinetochores. The motion of kinetochores throughout mitosis is intricate and automated quantitative tracking of their motion has already revealed many surprising facets of their behaviour. Here, we present 'KiT' (Kinetochore Tracking)-an easy-to-use, open-source software package for tracking kinetochores from live-cell fluorescent movies. KiT supports 2D, 3D and multi-colour movies, quantification of fluorescence, integrated deconvolution, parallel execution and multiple algorithms for particle localization. KiT is free, open-source software implemented in MATLAB and runs on all MATLAB supported platforms. KiT can be downloaded as a package from http://www.mechanochemistry.org/mcainsh/software.php The source repository is available at https://bitbucket.org/jarmond/kit and under continuing development.

    One of the research projects undertaken during the implementation of the IAEA Technical Assistance Cooperation Program in our department was inhouse production of sestamibi (MIBI) kit to be labelled with Tc99m pertechnetate for myocardial studies and for malignant tumor imaging. 100 mg raw materials of sestamibi was supplied by IAEA and the kit was prepared based on Janoki recipe. Using 6 mg MIBI, 192 mg glycine, 3.6 mg stannous chloride, 62.4 mg Na sub 4 Po sub 4 and 24 mg cysteine we have prepared 24 vials of MIBI kit under sterile condition and stored in the freezer at -70 degree C. The sterility of the kit was confirmed by microbiological test using cultured method. The stability test was done by labelling the kit with Tc-99m pertechnetate at day 1, 3, 7, 30 and 60 days after kit preparation. Using two system butanone and saline with ITLC the labelling efficiency of Tc-99m (MIBI) was found to be more than 90% in each case. The labelling efficiency was found to maintain at 90% up to 24 hours post reconstitution at room temperature. Biodistribution study was carried out by administering Tc-99m (MIBI) to mice intravenously at the dosage of IOO {mu} Ci per 20 gm body weight. The mice were sacrificed at 3 hours and 24 hours after the dose administration. Blood, heart, lung, intestine, kidney and stomach samples were obtained, weighed and measured for radioactivity using gamma well counter. The data showed that after 3 hours about 60% of the injected dose accumulated in the intestine which was in agreement with IAEA standard. At 24 hours the amount in the heart still remained about 25% of the 3 hour uptake. In house production of MIBI kit is easy, fast and cost effective. The data suggested that the quality of our kit was good enough to be used for further animal research and clinical trials.

    During the insertion appointment, the practitioner is often faced with the need to adjust ceramic surfaces to fit a restoration to the adjacent or opposing dentition and soft tissues. The purpose of this study was to assess the ceramic surface smoothness achieved with various commercially available ceramic polishing kits on different commonly used ceramic systems. The reliability of the cost of a polishing kit as an indicator of improved surface smoothness was assessed. A total of 350 ceramic surfaces representing 5 commonly available ceramic systems (IPS Empress Esthetic, IPS e.max Press, Cergo Kiss, Vita PM 9, Imagine PressX) were treated with 5 types of ceramic polishing systems (Cerapreshine, 94006C, Ceramiste, Optrafine, Zenostar) by following the manufacturers' guidelines. The surface roughness was measured with a profilometer (Taylor Hobson; Precision Taylor Hobson Ltd). The effects of ceramic systems and polishing kits of interest on surface roughness were analyzed by 2-way ANOVA, paired t test, and Bonferroni corrected significance level. The ceramic systems and polishing kits statistically affected surface roughness (Pceramic surface. No correlation could be established between the high cost of the polishing kit and low surface roughness. None of the commonly used ceramic polishing kits could create a surface smoother than that of glazed ceramic (Pceramic polishing kits is not recommended as a reliable indicator of better performance of ceramic polishing kits (P>.30).

    This special dossier treats of the changes that will happen in France with the deregulation of energy markets. It comprises 19 articles dealing with: the big bang of July 1, 2004 in the electricity and gas sector (on July 1, 2004, all professional consumers will have the possibility to chose their electricity and gas supplier. If Electricite de France (EdF) and Gaz de France (GdF) monopolies will split up, several questions remain unanswered for clients); the impossible penetration of the French market (3 weeks before the enhanced opening of power markets, EdF's competitors remain surprisingly limited and are mainly French actors. The big European competitors follow a wait-and-see policy); the independent power producer Compagnie Generale du Rhone wants to diversify its clients and is looking towards local authorities; Direct Energie: the 'low-cost' company for the mutualization of electricity purchases of small professionals; Endesa, the French daughter company of the Spanish electric utility, is looking for a balance between production and sales; HEW, daughter company of Vattenfall Europe and present in France since April 2000, wants to increase its margins more than its capacity; energy profilers are making consumption profiles for EdF's competitors; Poweo, energy retailing company built in 2002, is fetching very small companies; Atel, French daughter company of the Swiss power producer, does not foresee important changes in July 1; interview of F. Roussely, head of EdF about the liberalization of the electricity sector; the main energy groups favorable to deregulation; case study: Accor, the hotel trade group, has chosen Compagnie Generale du Rhone as power supplier; electricity: why prices are increasing; various foreign experiences; UK: the consolidation time (fully liberalized and privatized between several companies, the British energy market is under total re-building); USA: the deregulation process has failed and stays stuck to 24 states; Spain: the industry is the main beneficiary of market opening (opened since January 1, 2003, the Spanish energy market has not changed much: the regulated prices remain attractive); the Netherlands make a liberalization wind blow (de-regulated since the mid 1980's, the Dutch electricity market is living at the rhythm of prices drops and consumers whims); interview of J.

    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.

    kit's guided structure of inquiry and the collaboration both affected the inservice teachers in the following ways: The coteaching model supported behavioral and material management issues caused by the implementation of the kits; collaboration with preservice teachers created a "smaller-class-size" effect, which allowed teachers to attend to a smaller number of students for cooperative learning and assessment, and the elementary inservice teachers learned pedagogical strategies and science content from collaborating with secondary preservice teachers in kit use and from the kits' curriculum. Results were used as a self-study for future training and support for implementation of inquiry-based kits.

    KIT, a transmembrane receptor tyrosine kinase, is one of the specific targets for anti-cancer therapy. 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.

    To evaluate a home-made ELISA kit for detection of Helicobacter pylori (Hp) infection and comparison of its immunologic criteria with those of foreign commercial kits. A home-made IgG ELISA kit was developed using soluble antigenic fractions of Hp proteins. Confirmed sera were tested and serological criteria were evaluated through assessment of 199 serum samples. The accuracy, sensitivity and specificity values of home-made kit were 92, 92 and 90.4%, respectively. These immunologic criteria for Trinity kit were 95.2, 95.2 and 95% in comparison with IBL kit (91.3, 92.2 and 88.5%), BIOHIT kit (72.4, 41.6 and 94.1%) and HelicoBlot2.1 (94.2, 93.4 and 100%). Kappa agreement assessment demonstrated that two of the imported ELISA kits had fair to moderate agreement with the home-made kit while the other one had a poor agreement value. Apart from comparable values between the home-made kit and the most efficient imported kit (Trinity) there was significant cost benefit. Therefore, we recommend the home-made kit as a suitable substitution for detection of Hp infection in the Iranian population.

    The non-specific background reaction produced in avidin-biotin-based immunohistochemistry, particularly after harsh antigen retrieval procedures, has promoted the use of non-avidin-biotin systems, yet there are few reports comparing the performance of non-avidin-biotin, polymer-based methods. In this study we compare two of these methods, ENVISION+trade mark and ImmPRESS, in animal tissues. We examined the immunoreactivity of 18 antigens in formalin-fixed, paraffin-embedded tissues. Antigens were located in the cytoplasmic membrane (CD11d, CD18 and CD79a), cytoplasm (calretinin, COX-1, COX-2, Glut-1, HepPar 1, KIT, Melan A, tryptase and uroplakin III) or nucleus (MUM-1, PGP 9.5 and thyroid transcription factor 1). We also evaluated three infectious agents (Aspergillus, calicivirus and West Nile virus). The staining with ENVISION+ or ImmPRESS was performed simultaneously for each antigen. The intensity of the reaction and background staining were scored. ImmPRESS yielded similar or higher reaction intensity than ENVISION+trade mark in 16/18 antigens. ImmPRESS produced abundant background with the other two antigens (calretinin and COX-2), which hindered interpretation of the specific reaction. The cost of ImmPRESS was 25% lower than for ENVISION+trade mark. Based on these results, ImmPRESS is a good polymer-based detection system for routine immunohistochemistry.

    Full Text Available BackgroundSecond-generation thyroglobulin immunometric assays (Tg-IMAs have been developed with improved sensitivity. Our aim was to compare the diagnostic value of Tg-IMA measurements using a Kryptor (BRAHMS AG kit (Tg-K and an ACCESS (Beckman Coulter kit (Tg-A with that of the first-generation Tg measurement using a Tg-plus (BRAHMS AG kit (Tg+.MethodsWe enrolled 82 differentiated thyroid cancer patients who underwent total thyroidectomy with radioactive iodine remnant ablation and who underwent diagnostic whole body scan using recombinant human thyroid stimulating hormone (rhTSH. The Tg+, Tg-K, and Tg-A were measured before rhTSH administration during levothyroxine treatment (suppressed Tg from the same sample. Serum Tg+ was measured after rhTSH stimulation (stimulated Tg.ResultsSuppressed Tg+ was more significantly correlated with suppressed Tg-K (R2=0.919, P<0.001 than with suppressed Tg-A (R2=0.536, P<0.001. The optimal cut-off values of suppressed Tg+, Tg-K, and Tg-A for predicting stimulated Tg+ of 1 ng/mL were 0.3, 0.2, and 0.2 ng/mL, respectively. The sensitivity, specificity, and accuracy of suppressed Tg+ were 67%, 100%, and 90%, respectively; those of suppressed Tg-K were 83%, 90%, and 88%; those of suppressed Tg-A were 96%, 82%, and 87%, respectively. The positive predictive and negative predictive values of Tg+ were 100% and 87%, respectively; those of Tg-K were 79% and 92%; and those of Tg-A were 73% and 98%.ConclusionWe could not clearly demonstrate which kit had better diagnostic performance after comparison of first-generation Tg measurements with Tg-IMA measurements. Also, there were kit-to-kit variations between Tg-IMA kits. Suppressed Tg measured by Tg-IMA was insufficient to completely substitute for a stimulated Tg measurement.

    Biological significance of c-Kit as a cardiac stem cell marker and role(s) of c-Kit+ cells in myocardial development or response to pathological injury remain unresolved because of 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. The main objectives of this study are as follows: demonstrating 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; and providing perspective to reconcile disparate viewpoints on c-Kit biology in the myocardium. 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 (enhanced green fluorescent protein; 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 that from 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

    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

  17. Radiology seminars using teaching kits

    Munro, T.G.

    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

  18. Prediction of Pressing Quality for Press-Fit Assembly Based on Press-Fit Curve and Maximum Press-Mounting Force

    Directory of Open Access Journals (Sweden)

    Bo You

    2015-01-01

    Full Text Available In order to predict pressing quality of precision press-fit assembly, press-fit curves and maximum press-mounting force of press-fit assemblies were investigated by finite element analysis (FEA. The analysis was based on a 3D Solidworks model using the real dimensions of the microparts and the subsequent FEA model that was built using ANSYS Workbench. The press-fit process could thus be simulated on the basis of static structure analysis. To verify the FEA results, experiments were carried out using a press-mounting apparatus. The results show that the press-fit curves obtained by FEA agree closely with the curves obtained using the experimental method. In addition, the maximum press-mounting force calculated by FEA agrees with that obtained by the experimental method, with the maximum deviation being 4.6%, a value that can be tolerated. The comparison shows that the press-fit curve and max press-mounting force calculated by FEA can be used for predicting the pressing quality during precision press-fit assembly.

    Western Research Institute (WRI) has developed a new commercial product ready for technology transfer, the Diesel Dog{reg_sign} Portable Soil Test Kit, for performing analysis of fuel-contaminated soils in the field. The technology consists of a method developed by WRI (U.S. Patents 5,561,065 and 5,976,883) and hardware developed by WRI that allows the method to be performed in the field (patent pending). The method is very simple and does not require the use of highly toxic reagents. The aromatic components in a soil extract are measured by absorption at 254 nm with a field-portable photometer. WRI added significant value to the technology by taking the method through the American Society for Testing and Materials (ASTM) approval and validation processes. The method is designated as ASTM Method D 5831-96, Standard Test Method for Screening Fuels in Soils. This ASTM designation allows the method to be used for federal compliance activities. In June 2001, the Diesel Dog technology won an American Chemical Society Regional Industrial Innovations Award. To gain field experience with the new technology, Diesel Dog kits have been used for a variety of site evaluation and cleanup activities. Information gained from these activities has led to improvements in hardware configurations and additional insight into correlating Diesel Dog results with results from laboratory methods. The Wyoming Department of Environmental Quality (DEQ) used Diesel Dog Soil Test Kits to guide cleanups at a variety of sites throughout the state. ENSR, of Acton, Massachusetts, used a Diesel Dog Portable Soil Test Kit to evaluate sites in the Virgin Islands and Georgia. ChemTrack and the U.S. Army Corps of Engineers successfully used a test kit to guide excavation at an abandoned FAA fuel-contaminated site near Fairbanks, Alaska. Barenco, Inc. is using a Diesel Dog Portable Soil Test Kit for site evaluations in Canada. A small spill of diesel fuel was cleaned up in Laramie, Wyoming using a Diesel

    The growth factor receptor Kit is involved in hematopoietic and nonhematopoietic development. Mice bearing Kit defects lack mast cells; however, strains bearing different Kit alleles exhibit diverse phenotypes. Herein, we investigated factors underlying differential sensitivity to IgG-mediated arthritis in 2 mast cell-deficient murine lines: KitWsh/Wsh, which develops robust arthritis, and KitW/Wv, which does not. Reciprocal bone marrow transplantation between KitW/Wv and KitWsh/Wsh mice revealed that arthritis resistance reflects a hematopoietic defect in addition to mast cell deficiency. In KitW/Wv mice, restoration of susceptibility to IgG-mediated arthritis was neutrophil independent but required IL-1 and the platelet/megakaryocyte markers NF-E2 and glycoprotein VI. In KitW/Wv mice, platelets were present in numbers similar to those in WT animals and functionally intact, and transfer of WT platelets did not restore arthritis susceptibility. These data implicated a platelet-independent role for the megakaryocyte, a Kit-dependent lineage that is selectively deficient in KitW/Wv mice. Megakaryocytes secreted IL-1 directly and as a component of circulating microparticles, which activated synovial fibroblasts in an IL-1-dependent manner. Transfer of WT but not IL-1-deficient megakaryocytes restored arthritis susceptibility to KitW/Wv mice. These findings identify functional redundancy among Kit-dependent hematopoietic lineages and establish an unanticipated capacity of megakaryocytes to mediate IL-1-driven systemic inflammatory disease.

    2013-01-01

    Urinary bladder squamous cell carcinoma (SCC), one of the most common neoplasms in Egypt, is attributed to chronic urinary infection with Schistosoma haematobium (Schistosomiasis). The proto-oncogene c-KIT, encoding a tyrosine kinase receptor and implicated in the development of a number of human malignancies, has not been studied so far in schistosomal urinary bladder SCCs. We therefore determined immunohistochemical (IHC) expression of c-KIT in paraffin sections from 120 radical cystectomies of SCCs originally obtained from the Pathology Department of Suez Canal University (Ismailia, Egypt). Each slide was evaluated for staining intensity where the staining extent of >10% of cells was considered positive. c-KIT overexpression was detected in 78.3% (94/120) of the patients, the staining extents in the tumor cells were 11-50% and >50% in 40 (42.6%) and 54 (57.4%) respectively. The positive cases had 14.9%, 63.8%, 21.3% as weak, moderate and strong intensity respectively. Patients with positive bilharzial ova had significantly higher c-KIT expression than patients without (95.2% vs. 38.9%, P=0.000). Mutation analysis of exons 9-13 was negative in thirty KIT positive cases. The high rate of positivity in SBSCC was one of the striking findings; However, CD117 may be a potential target for site specific immunotherapy to improve the outcome of this tumor.

    International Nuclear Information System (INIS)

    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

    2017-10-01

    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.

  15. A simple kit for rapid field diagnosis of potato virus Y by latex serological test

    Directory of Open Access Journals (Sweden)

    Aarne Kurppa

    1987-07-01

    Full Text Available A simple kit for rapid detection of potato virus Y by latex serological test was developed. The test is carried out on a white cardboard sheet and the results can be read by naked eye in two minutes. A test card of 10 x 6 cm holds latex sensitized antibodies, buffers and other necessary ingredients as dry blue colored formulate on the ringed areas of the card. A test card includes space for six tests and positive and negative controls. The kit also includes disposable plastic sticks for mixing the samples with test reagents and a hand press with disposable plastic tips. For testing, dried reagents are dissolved in drops of sample and mixed. After gentle rotation, samples containing virus appear clearly granulated while samples from healthy plants remain unagglutinated. The testing of undiluted extracts of evenly developed tuber sprouts resulted in over 91 % identity with the results obtained with ELISA that was used as a control method. Testing of diluted leaf extracts reached the same reliability but undiluted leaf extracts from glasshouse grown potatoes were not well suitable as test samples because of their dark green color. No such problems occurred with field grown material and a complete identity with the ELISA readings was true when the samples included secondarily infected potato plants. No reaction to other potato viruses than PVY was obtained by the test kit.

    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.

    Battaglia, D.J.; Cianci, M.L.

    1976-01-01

    Iodine-125-digoxin radioimmunoassay kits available from Abbott Diagnostics (AD), Dade Division (D), Schwarz/Mann (SM), and Clinical Assays (CA) were evaluated with respect to assay quality. The kit accuracies did not differ significantly at 2.0 ng/ml and the interassay coefficients of variation ranged from 9 percent (AD) to 21.4 percent (CA). The accuracy for all kits above 4 ng/ml is questionable, and since serum-dilution values correlated well with undiluted serum values, the dilution method of dose quantitation is preferable for levels above 4 ng/ml. Although all the kits were adequate for evaluating digoxin at the 2 ng/ml level, the Abbott kit seems to be of slightly better quality

    This paper presents the preparation of Albumin (Alb) radioimmunoassay kit and its preliminary clinical application. The kit is mainly applied to the measurement of Alb concentration in human urine, adopting second antibody-PEG method. The measurement range is (1-50 μg/ml). The curve obtained with a serially diluted urine sample of high Alb concentration was a straight line. Recovery, detectability, intra- and inter-batch variation coefficients were 95.7%-103.6%, 0.1 μg/ml, 5.8% and 6.4% respectively. The kit was tried out clinically for measuring Alb in urine samples in about 1200 normal individuals and 600 various patients of related renal diseases. The preliminary clinical results show that Alb RIA is conducive to the early diagnosis of kidney function abnormalities

    Introduction: Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor arising from the gastrointestinal tract and highly expresses mutated c-kit. We aimed to develop a specific and sensitive method for detecting GISTs using radiolabeled anti-c-kit monoclonal antibody. Methods: A mutated c-kit-expressing cell clone was established by transfecting an expressing vector of mutated c-kit gene into HEK293 human embryonic kidney cells. The tumors were developed by inoculating c-kit-expressing cells into nude mice. 125 I- and 111 In-labeled anti-c-kit antibodies (12A8 and 41A11) were evaluated in vitro by cell binding, competitive inhibition and cellular internalization assays, and in vivo by biodistribution and imaging studies in tumor-bearing mice. Results: Both 125 I- and 111 In-labeled antibodies showed specific binding with c-kit-expressing cells with high affinity (dissociation constants = 2.2-7.1x10 9 M -1 ). Internalization assay showed that 125 I-labeled antibodies were rapidly internalized and dehalogenated, with the release of 125 I from the cells, resulting in reduction of cell-associated radioactivity with time. In contrast, 111 In-labeled antibody was internalized but did not result in the reduced radioactivity associated with tumor cells. Reflecting this phenomenon, the in vivo tumor uptake of 125 I-labeled antibody was low on Day 1, further decreasing with time, while tumor uptake of 111 In-labeled antibody was high on Day 1, further increasing with time. The xenografted tumor was clearly visualized by scintigraphy after injection of 111 In-labeled antibody. Conclusion: The anti-c-kit monoclonal antibody labeled with a metal radionuclide would be promising for c-kit-targeted imaging of GISTs.

    Deregulation of the receptor tyrosine kinase c-Kit is associated with an increasing number of human diseases, including certain cancers and mast cell diseases. Interference of c-Kit signaling with multi-kinase inhibitors has been shown clinically to successfully treat gastrointestinal stromal tumors and mastocytosis. Targeted therapy of c-Kit activity may provide therapeutic advantages against off-target effects for non-oncology applications. A new structural class of c-Kit inhibitors is described, including in vitro c-Kit potency, kinase selectivity, and the observed binding mode.

    Introduction: C-kit is an important diagnostic and therapeutic target molecule for several malignancies, and c-kit-targeted drugs have been used clinically. Because abundant c-kit expression in tumors is a prerequisite for successful c-kit-targeted therapy, imaging of c-kit expression is expected to play a pivotal role in the therapeutic decision for each patient. We evaluated 64 Cu-labeled Fab of anti-c-kit antibody 12A8 as a positron emission tomography (PET) imaging probe. Methods: 111 In- or 125 I-Labeled 12A8 Fab was evaluated in vitro by cell binding, competitive inhibition and cellular internalization assays, and in vivo by biodistribution in mice bearing c-kit-expressing and -non-expressing tumors. Next, Fab fragment was labeled with the positron emitter 64 Cu and evaluated by PET. Results: Radiolabeled 12A8 Fab showed specific binding to c-kit-expressing cells with high affinity and internalized into cells after binding to c-kit on cell surface. Although tumor accumulation of [ 111 In]Fab was lower than that of [ 111 In]IgG, the faster blood clearance of [ 111 In]Fab provided higher tumor-to-blood ratio at 6 h postinjection onwards. Blood clearance of 64 Cu-labeled 12A8 Fab was slower than that of [ 111 In]Fab, but PET using [ 64 Cu]Fab clearly visualized the tumor at 6 h postinjection onwards. Conclusion: The 64 Cu-labeled 12A8 Fab could be used for c-kit-specific PET imaging and might help in selecting appropriate patients for c-kit-targeted treatments.

    This special dossier treats of the changes that will happen in France with the deregulation of energy markets. It comprises 19 articles dealing with: the big bang of July 1, 2004 in the electricity and gas sector (on July 1, 2004, all professional consumers will have the possibility to chose their electricity and gas supplier. If Electricite de France (EdF) and Gaz de France (GdF) monopolies will split up, several questions remain unanswered for clients); the impossible penetration of the French market (3 weeks before the enhanced opening of power markets, EdF's competitors remain surprisingly limited and are mainly French actors. The big European competitors follow a wait-and-see policy); the independent power producer Compagnie Generale du Rhone wants to diversify its clients and is looking towards local authorities; Direct Energie: the 'low-cost' company for the mutualization of electricity purchases of small professionals; Endesa, the French daughter company of the Spanish electric utility, is looking for a balance between production and sales; HEW, daughter company of Vattenfall Europe and present in France since April 2000, wants to increase its margins more than its capacity; energy profilers are making consumption profiles for EdF's competitors; Poweo, energy retailing company built in 2002, is fetching very small companies; Atel, French daughter company of the Swiss power producer, does not foresee important changes in July 1; interview of F. Roussely, head of EdF about the liberalization of the electricity sector; the main energy groups favorable to deregulation; case study: Accor, the hotel trade group, has chosen Compagnie Generale du Rhone as power supplier; electricity: why prices are increasing; various foreign experiences; UK: the consolidation time (fully liberalized and privatized between several companies, the British energy market is under total re-building); USA: the deregulation process has failed and stays stuck to 24 states; Spain: the industry is the main beneficiary of market opening (opened since January 1, 2003, the Spanish energy market has not changed much: the regulated prices remain attractive); the Netherlands make a liberalization wind blow (de-regulated since the mid 1980's, the Dutch electricity market is living at the rhythm of prices drops and consumers whims); interview of J. Syrota, head of the energy regulation commission. (J.S.)

  11. AREVA in Mongolia - Press kit

    International Nuclear Information System (INIS)

    2013-01-01

    Mongolia is going through a crucial period in its history and setting up a strategic policy for uranium. The choices that are being made will affect the country and its future. Mongolia, since the mid-2000's, has benefited from significant mining development that has nourished the strong growth of the country. The giant Oyu Tolgoi (gold and copper) and Tavan Tolgoi (coal) deposits are the symbols of this mining potential. Uranium in particular has a major strategic role. The exploration programmes have revealed the presence of exploitable resources. On 26 February 2013, the Professional Council of Mineral Resources with the Ministry of Mines officially classified the Zoovch Ovoo deposit's with more than 50 000 tons of uranium. Following classification of the deposit of Dulaan Uul in 2011, the Zoovch Ovoo classification makes Mongolia officially one of the top 10 countries with the largest uranium resources. Mongolia has set about making the uranium industry a centrepiece of its strategy and its policy of independence. This new approach is founded in the Nuclear Energy Act adopted in the summer of 2009. The Mongolian State wants to create a uranium industry that makes Mongolia a nuclear fuel supplier for the Asian market. The choice of partners with whom the country associates to mine the uranium deposits is therefore important. Agreements have notably entered into with France, through AREVA which is a public company, as well as with Russia, China, Japan and India. AREVA has been present in Mongolia since 1997. AREVA is today represented in Mongolia by AREVA Mongol, its 100% subsidiary. AREVA Mongol carries out its exploration activities through Cogegobi and will manage its mining licences through AREVA Mines LLC. AREVA holds several exploration licences in Mongolia covering over 9,000 km 2 in the provinces of Dornogobi and Sukbaatar, where COGEGOBI is conducting its drilling programmes. This first phase has led to the first project-development steps (hydrogeological tests, certification of the resources, in situ recovery tests, etc.) in the Dulaan Uul area ('Hot Mountain' in Mongolian) in a vast sedimentary basin of the Gobi desert. The geological data enabling a technical and economic feasibility of the mining project are being collected by AREVA with respect for the environment and in partnership with the Mongolian authorities

    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.

    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

    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...

    2012-11-01

    The goal of this project is to develop a fluid dynamics demonstration/experiment kit that can be used by professors and graduate students at high school outreach events. The demonstrations in the kit will be easy to use and true crowd pleasers in order to inspire understanding and pique curiosity about the physics of flow. The kits will be inexpensive, containing readily available materials so that teachers can duplicate the demonstrations and experiments. The kits will be left with the teachers as a gift from the American Physics Society. The experiments and demonstrations cover the concepts of conservation of mass, momentum, and energy, Bernoulli's equation, frictional losses and the ideal gas law. For each experiment, the teachers will receive presentation material, access to instructional videos, plus a worksheet that can be used in a high school physics classroom. This kit has been developed through the efforts of the APS-DFD Mentoring and Outreach Committee and has received funding from the APS-DFD. Work funded by the APS-DFD.

    Protein kinase signal-transduction pathways play critical roles in regulating nociception. The c-kit receptor contributes to pain regulation in the spinal cord and is present on both peripheral and central terminals. Expression of c-kit was demonstrated in human trigeminal and spinal ganglia. However, the brainstem expression of c-kit was overlooked. We aimed to evaluate it by immunohistochemistry, on eight samples of human lower medulla oblongata. We used two clones of CD117/c-kit antibodies, from different manufacturers, and neurofilament antibodies. Positive expression of CD117/c-kit was found within the spinal trigeminal nucleus, the gracilis, cuneate, and lateral cuneate nuclei, and within the olivary complex. CD117/c-kit positive interstitial networks of these nuclei were positively labeled with neurofilaments. CD117/c-kit labeled the olivary neurons, but not the magnocellular neurons of the trigeminal, gracilis and cuneate nuclei. c-kit interstitial systems of brainstem could play so an important role for the functional status along the somatosensory neural circuits.

    Objective: To provide data for perfect selection of glutamic acid decarboxylase antibodies (GAD-Ab) assay commercial kits. Methods: The sera of 88 titer-graded samples by radioligand assay (RLA) were measured with two types of enzyme-linked immunosorbent assay (ELISA) kits and one type of immunoradiometric assay (IRMA) kit for GAD-Ab in order to test their consistency with RLA. Another 140 diabetic sera were measured with RLA and screened by a type of suitable kit to search the cutoff point for discriminating patients who needed rechecking. Results: Compared with RLA, concordance ratio of 3 kits: Medizym kit(75%) > RSR kit(73.9%) > Biomerica kit(62.5%); Kappa value: Medizym kit (0.408, common) > RSR kit (0.405, common) > Biomerica kit (0.185, failing); correlation to RLA index: RSR kit (r= 0.992) > Medizym kit(r= 0. 791 ) > Biomerica kit (r = -0. 055); area under the receiver operating characteristic (ROC) curve: Medizym kit (0.812) > RSR kit (0. 727 ) > Biomerica kit (0.666). Conclusions: The efficiencies of RSR kit and Medizym kit are good. Serum concentration between 0.25-0.99 U/ml measured by RSR kit is suggested to further recheck by RLA. (authors)

    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.).

    Problems have been reported with the use of kit-produced /sup 99m/Tc radiopharmaceuticals. This study was undertaken to understand the chemistry involved in various stannous kit systems. The relation between Tc, tin, and the ligands used to complex the reduced Tc was investigated. It is concluded that for reliable performance, stannous kits should be prepared so that most of the tin is kept in the usable (reducing) form; a solution would be to use minimum tin and a large excess of complexing agent. Oxidation of the Tc complex to free pertechnetate is not a major problem in most kit systems. 5 figures

    While it is important to monitor dental water quality, it is unclear whether in-office test kits provide bacterial counts comparable to the gold standard method (R2A). Studies were conducted on specimens with known bacterial concentrations, and from dental units, to evaluate test kit accuracy across a range of bacterial types and loads. Colony forming units (CFU) were counted for samples from each source, using R2A and two types of test kits, and conformity to Poisson distribution expectations was evaluated. Poisson regression was used to test for effects of source and device, and to estimate rate ratios for kits relative to R2A. For all devices, distributions were Poisson for low CFU/mL when only beige-pigmented bacteria were considered. For higher counts, R2A remained Poisson, but kits exhibited over-dispersion. Both kits undercounted relative to R2A, but the degree of undercounting was reasonably stable. Kits did not grow pink-pigmented bacteria from dental-unit water identified as Methylobacterium rhodesianum. Only one of the test kits provided results with adequate reliability at higher bacterial concentrations. Undercount bias could be estimated for this device and used to adjust test kit results. Insensitivity to methylobacteria spp. is problematic.

    Full Text Available The purpose of this research is to analyse, through three national daily newspapers which represent the French press, how this press is related Lebanon, during a turbulent period full of events. This period starts the week of September 19, 1988, the last week of mandate of President Amine Gemayel who appoints a transational government boycotted by the “Muslim side”. It ends on May 13, 1991, date of the signature of cooperation treaty between Lebanon and Syria. The thesis leads, on one hand, to highlighting the links between the representation of Lebanon in the press and the socio-political history of France, its diplomacy and the issues of internal policy, and on the other hand, highlighting the complexity of elaborating a coherent daily information marked by the permanent need of landmarks within a political world.

  13. Utilization of milk energy by suckling mink kits

    2004-01-01

    A total of 36 mink dams and their litters of 3, 6 or 9 kits were used for determination of milk intake of the suckling young by means of deuterium dilution technique, and chemical composition of milk and of kit bodies. Measurements were performed during lactation weeks 1-4, each week with 3 dams...... with each litter size. Milk intake was determined over a 48 h measurement period, and by the end of this milk samples were collected and 2 kits (litters of 6 and 9) or 1 kit per litter (litters of 3) were killed for body chemical composition. Based on the results, different models were applied...... for calculation of the energetic efficiency of milk. Dam milk yield increased steadily from week 1 until week 3 but only slightly from week 3 to 4. The increase declined with increasing litter size, and for dams suckling 9 kits the increment from week 3 to week 4 was only 2 g. The dry matter content of milk...

    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 %).

    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.

    During the early part of the 1970s a need arose for suitable aids to assist lecturers in giving talks on radioactivity and radiation to employees and occasionally to science students in local schools and colleges. A kit capable of demonstrating the basic properties of alpha, beta and gamma radiation was assembled for these purposes. During the latter half of the decade a demand arose for talks to non-scientific groups of the general public on nuclear power and radiation and some of the items in the original demonstration kit were found to be appropriate for these talks. The items used, now constitute the Basic Demonstration Kit. Meanwhile, a few changes or additions were made to the original kit which is now known as the Comprehensive Demonstration Kit. (author)

  18. Association of KIT exon 9 mutations with nongastric primary site and aggressive behavior: KIT mutation analysis and clinical correlates of 120 gastrointestinal stromal tumors.

    Activating mutations of the KIT juxtamembrane region are the most common genetic events in gastrointestinal stromal tumors (GISTs) and have been noted as independent prognostic factors. The impact of KIT mutation in other regions, such as the extracellular or kinase domains, is not well-defined and fewer than 30 cases have been published to date. One hundred twenty GISTs, confirmed by KIT immunoreactivity, were evaluated for the presence of KIT exon 9, 11, 13, and 17 mutations. The relation between the presence/type of KIT mutation and clinicopathological factors was analyzed using Fisher's exact test and log-rank test. Forty-four % of the tumors were located in the stomach, 47% in the small bowel, 6% in the rectum, and 3% in the retroperitoneum. Overall, KIT mutations were detected in 78% of patients as follows: 67% in exon 11, 11% in exon 9, and none in exon 13 or 17. The types of KIT exon 11 mutations were heterogeneous and clustered in the classic "hot spot" at the 5' end of exon 11. Seven % of cases showed internal tandem duplications (ITD) at the 3' end of exon 11, in a region that we designate as a second hot spot for KIT mutations. Interestingly, these cases were associated with: female predominance, stomach location, occurrence in older patients, and favorable outcome. There were significant associations between exon 9 mutations and large tumor size (P < 0.001) and extragastric location (P = 0.02). Ten of these 13 patients with more than 1-year follow-up have developed recurrent disease. Most KIT-expressing GISTs show KIT mutations that are preferentially located within the classic hot spot of exon 11. In addition, we found an association between a second hot spot at the 3'end of exon 11, characterized by ITDs, and a subgroup of clinically indolent gastric GISTs in older females. KIT exon 9 mutations seem to define a distinct subset of GISTs, located predominantly in the small bowel and associated with an unfavorable clinical course.

  19. Densification of boron carbide at relatively low temperatures by hot pressing and hot isostatic pressing

    Telle, R.

    1988-01-01

    The poor sinterability of B 4 C limits its widespread application because both high temperatures and high pressures are required for a complete densification. Moreover, B 4 C suffers from a low strength and fracture toughness, possesses, however, a high potential because of its extreme hardness. Reaction hot pressing of B 4 C-WC-TiC-Si-Co mixtures resulting in B 4 C-TiB 2 -W 2 B 5 composites of high density exhibit remarkable mechanical properties. The influence of hot isostatic pressing (HIP) on the microstructure and the mechanical properties is investigated in cooperation with participants of the COST 503 activities and related to the strengthening and toughening mechanisms. Difficulties during densification by HIP arise from the evaporation of adsorbed volatiles as well as from the strong swelling of the powder compact due to the sintering reaction. Several HIP cycle designs were tested in order to prevent the bloating of the capsule and to control internal stresses due to the misfit of the thermal expansion of the entire phases. In comparison to single phase B 4 C ceramics, bending strength was improved to 1030 MPa, K Ic to 5.2 MPa/m, while hardness was comparable with HV1=38 GPa. Wear test were performed and related to the toughening mechanisms. (orig.) With 56 refs., 9 tabs., 64 figs

    As for the influences of Chuetsu-Oki Earthquake on Kashiwazaki-Kariwa Nuclear Power Station, we can conclude that 'the safety function of the nuclear power station, that is, 'Shutdown', 'Cooling down' and 'Isolating' functioned as per designed even against earthquake beyond assumption, and fundamental nuclear safety could be assured'. Nevertheless, it is said that one of the causes that harmful rumor had spread was due to mass communication media. In the press reports on some nuclear power station when affected by an earthquake and on trouble in the nuclear power station in the future, we will propose that the publication should be really useful for habitants and citizens and be promoted in the positive and expected direction, in order not to make the same mistake as this time. JSME should aim at implement the above-mentioned proposal under cooperation with other academic societies and organizations. (author)

    Full Text Available In this paper, we will present the impact of the conditions in pressing chambers during the pressing of wooden briquettes. The conditions in pressing chambers can significantly impact the resulting compacting pressure required for the pressing of briquettes. In the introduction, we show which parameters of the pressing chamber during pressing can impact the resulting compacting pressure. The experiment results which are shown in this paper described the detected impact of some important pressing chamber parameters. This experiment aims to detect the pressing chamber length impact and the impact of the way of pressing. By setting the pressing conditions, we will be able to achieve the suitable resulting compacting pressure with respect to the required final briquettes quality.

    We examined Cortisol Kit TFB for direct assay of urine cortisol. And the multiplication by dilution factor of urine cortisol values in this kit was examined. The coefficient of correlation of cortisol levels (46 urine samples) between Cortisol Kit TFB and Chemilumi ACS-Cortisol II, which is another kit for direct assay of urine cortisol, was r=0.858, y=1.86x+38.2 (p<0.001). There were differences between the both cortisol levels of each urine sample in spite of the good coefficient of correlation. The urine cortisol values obtained from the standard curve in addition of 50 {mu}l of zero standard were 50-80% of the values obtained from the standard curve in the package insert. These results suggest that the specificity of the antibodies of both direct assay kits for urine cortisol may be different each other, and the multiplication by 1.09, the dilution factor due to the addition of zero standard to only urine sample, is unnecessary although it is indispensable for urine samples to add zero standard. Cortisol Kit TFB was very convenient for its easy assay procedure and short incubation. (author)

    2016-12-01

    Full Text Available Polish-German relations in the first half of 2014 were dominated by the Ukraine crisis. This study is an attempt to answer the question of how Polish and German press assessed the cooperation of both countries in resolving the conflict in Ukraine; to what extent the most widely read magazines associated themselves with the decisions of their politicians and the feelings of their own societies and how much understanding they showed for the arguments of their EU partner. The analysis focuses on the unprecedented mission of the Weimar Triangle foreign ministers to Ukraine in February 2014, which led to an agreement between the Ukrainian opposition and President Viktor Yanukovych. A turning point was the visit paid by Radoslaw Sikorski and Frank-Walter Steinmeier to St. Petersburg in June 2014. The next meetings agreed on by EU partners were held without inviting the Polish partner. In view of the speed of events in the selected time interval, the articles subjected to analysis were taken from the most widely read online editions of national daily newspapers in Poland and Germany.

    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

    c-kit (CD117) is a transmembrane tyrosine kinase that acts as a type III receptor for mast cell growth factor. In recent years, the role of c-kit in the development of preinvasive and invasive breast carcinomas has been investigated. The aim of our study was to detect c-kit expression in the entire spectrum of common benign and malignant breast lesions in correlation with a well-studied myoepithelial or stem-cell like marker (p63). We evaluated 270 cases of benign and malignant breast lesions including fibrocystic disease, fibroadenoma, sclerosing adenosis, atypical ductal hyperplasia, ductal/lobular carcinoma in situ, and ductal/lobular/mixed type carcinoma. C-kit staining was evaluated in the cytoplasm/cell membrane in epithelial and myoepithelial cells and p63 in the nuclei of myoepithelial cells. c-kit was highly expressed (85.3%) in benign lesions (fibrocystic disease, sclerosing adenosis, fibroadenoma), and p63 expression was 95.5% in the aforementioned lesions. c-kit distribution in preinvasive and invasive lesions was as follows: ductal/lobular carcinoma in-situ, 43%/35%; ductal/lobular carcinoma, 36%/39%; and mixed type carcinoma, 20%. c-kit was highly expressed in myofibroblast/fibroblast cells only in grade III ductal/lobular carcinomas. c-kit was totally absent in stromal cells in benign lesions and in situ carcinomas whereas expression was weak in grade I and II carcinomas. Combined overexpression of c-kit and p63 is indicative of benign breast lesions. In contrast, there is reduced expression of c-kit in in situ and invasive breast carcinomas, with simultaneous overexpression in the stromal cells. This suggests that c-kit may play a role in breast cancer progression.

    A pressing issue in biology and social sciences is to explain how cooperation emerges in a population of self-interested individuals. Theoretical models suggest that one such explanation may involve the possibility of changing one's neighborhood by removing and creating connections to others, but this hypothesis has problems when random motion is considered and lacks experimental support. To address this, we have carried out experiments on diluted grids with human subjects playing a Prisoner's Dilemma. In contrast to previous results on purposeful rewiring in relational networks, we have found no noticeable effect of mobility in space on the level of cooperation. Clusters of cooperators form momentarily but in a few rounds they dissolve as cooperators at the boundaries stop tolerating being cheated upon. Our results highlight the difficulties that mobile agents have to establish a cooperative environment in a spatial setting.

    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.

    The molecular mechanisms regulating the sensitivity of sensory circuits to environmental stimuli are poorly understood. We demonstrate here a central role for stem cell factor (SCF) and its receptor, c-Kit, in tuning the responsiveness of sensory neurons to natural stimuli. Mice lacking SCF/c-Kit signaling displayed profound thermal hypoalgesia, attributable to a marked elevation in the thermal threshold and reduction in spiking rate of heat-sensitive nociceptors. Acute activation of c-Kit by its ligand, SCF, resulted in a reduced thermal threshold and potentiation of heat-activated currents in isolated small-diameter neurons and thermal hyperalgesia in mice. SCF-induced thermal hyperalgesia required the TRP family cation channel TRPV1. Lack of c-Kit signaling during development resulted in hypersensitivity of discrete mechanoreceptive neuronal subtypes. Thus, c-Kit can now be grouped with a small family of receptor tyrosine kinases, including c-Ret and TrkA, that control the transduction properties of sensory neurons.

    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.

    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.

    It is critical to increase the uptake of interventions proven to be effective to improve maternal and perinatal outcomes. Supply kits have been suggested to be a feasible strategy designed to ensure timely availability and effective follow-up of care. We conducted a systematic review to summarize the evidence on the uptake, effectiveness and safety of supply kits for maternal care. MEDLINE, the Cochrane Pregnancy and Childbirth Group's Trials Register, Campbell Collaboration, Lilacs, Embase and unpublished studies were searched. Studies that reported the efficacy, safety and use of supply kits for maternal healthcare were eligible. Participants were pregnant women or in childbirth. Supply kits were defined as a collection of medicines, supplies or instruments packaged together with the aim of conducting a healthcare task. Two reviewers independently performed the screening, data extraction, and methodological and quality assessment. 24 studies were included: 4 of them were systematic reviews and 20 primary studies. Eighteen studies evaluated a so-called "clean delivery kit". In all but two studies, the kits were used by more than half of the participants. A meta-analysis was deemed inappropriate due to the heterogeneity in study design, in the components of the interventions implemented, in the content of the kits, and in outcomes. Nine studies assessed neonatal outcomes and found statistically significant reductions in cord infection, sepsis and tetanus-related mortality in the intervention group. Three studies showed evidence of reduced neonatal mortality (OR 0.52, 0.60 and 0.71) with statistically significant confidence intervals in all cases. Four studies reported odd ratios for maternal mortality, but only one showed evidence of a statistically significant decrease in this outcome but it was ascribed to hand washing prior to childbirth and not with the use of kits. This review suggests potential benefits in the use of supply kits to improve maternal and

    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.

    The aim of this study was the preparation of a liquid kit for radiolabeling of 188 Re-HEDP (hydroxyethylidene diphosphonate). 188 Re was obtained from alumina based 188 W/ 188 Re generators. This paper reports the efficacy of a cold kit stored for more than two weeks, determined by the dependence of the radiolabeling yields of 188 Re-HEDP on the incubation time, reducing agent concentration, the effects of concentration of ligand, the p H of the reaction and the temperature. The cold kits showed a good stability when carrie-free rhenium-188 was added in the reaction mixture. (author)

  2. Illusions of Friendship? The Soviet Union and Russia in the Finnish Press

    2004-07-01

    Full Text Available The image of the Soviet Union and Russia has changed dramatically in the press in Finland after the World War II. This article is based on a frequency analysis in which mentions of certain countries, groups of states and international organizations were coded (like the Soviet Union/Russia, United States, NATO, UN etc.. To make the analysis more revealing and interesting, a distinction was made whether the mention was made in the context of (1 alliance, friendship and cooperation, or in the context of (2 distance, restriction and enemy image, or (3 both in a positive and in a negative context. The time frame was from 1945 till the end of the century, and the newspapers chosen for the study represented the whole political spectrum of the Finnish media. The selection criteria of the material emphasized national celebration days. The study proves clearly what has been the main object of Finnish foreign policy after the WW II: in all coded press material, the Soviet Union/Russia was mentioned 222 times which makes 37.5% of all mentions. Other important states or groups have been the United States (5.3 %, EC/EU/WEU/West-Europe (12.6 %, United Nations (9.0 % and Nordic council/Nordic co-operation (11.2 %. With very few exceptions, all mentions concerning the UN and Nordic co-operation are positive. The Soviet Union has also been described rather positively (77.5 %. The share of negative mentions is 8.1% and mixture of negative and positive mentions 14.4%. Images of the United States and the European alliances are most contradictory. In the case of USA, 54.8 % of the mentions are positive and 45.2% negative. Concerning EC/EU etc. 54.1 % of mentions are positive, 28.4 % negative and 17.6 % mixtures of positive and negative references. Changes in attitudes towards the Soviet Union in different time spots are remarkable. The share of negative mentions of the Soviet Union was very low, except in 1995 (30 % when Finland already was a member of the EU

    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

    Iodobell in vivo kits provide an easy and fast method for 'on the spot' radioiodination with 123 I (or 131 I). Until now three kits have been developed in the Institute of Isotopes Budapest, the heptadecanoic acid, the hippurate and the MIBG kits. From these, the heptadecanoic acid kit is being tested in humans in Hungary, the other two are under the registration procedure. The Iodobell in vivo kits may contribute to the application of 123 I radioisotope in Hungary. (orig.)

  8. Evaluation of the kinase domain of c-KIT in canine cutaneous mast cell tumors

    2006-01-01

    Mutations in the c-KIT proto-oncogene have been implicated in the progression of several neoplastic diseases, including gastrointestinal stromal tumors and mastocytosis in humans, and cutaneous mast cell tumors (MCTs) in canines. Mutations in human mastocytosis patients primarily occur in c-KIT exon 17, which encodes a portion of its kinase domain. In contrast, deletions and internal tandem duplication (ITD) mutations are found in the juxtamembrane domain of c-KIT in approximately 15% of canine MCTs. In addition, ITD c-KIT mutations are significantly associated with aberrant KIT protein localization in canine MCTs. However, some canine MCTs have aberrant KIT localization but lack ITD c-KIT mutations, suggesting that other mutations or other factors may be responsible for aberrant KIT localization in these tumors. In order to characterize the prevalence of mutations in the phospho-transferase portion of c-KIT's kinase domain in canine MCTs exons 16–20 of 33 canine MCTs from 33 dogs were amplified and sequenced. Additionally, in order to determine if mutations in c-KIT exon 17 are responsible for aberrant KIT localization in MCTs that lack juxtamembrane domain c-KIT mutations, c-KIT exon 17 was amplified and sequenced from 18 canine MCTs that showed an aberrant KIT localization pattern but did not have ITD c-KIT mutations. No mutations or polymorphisms were identified in exons 16–20 of any of the MCTs examined. In conclusion, mutations in the phospho-transferase portion of c-KIT's kinase domain do not play an important role in the progression of canine cutaneous MCTs, or in the aberrant localization of KIT in canine MCTs

    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.

    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.

    Calcium is essential for normal bone growth and development. Inadequate calcium intake increases the risk of osteoporosis and fractures. Kit ligand/c-Kit signaling plays an important role in regulating bone homeostasis. Mice with c-Kit mutations are osteopenic. The present study aimed to investigate whether impairment of or reduction in c-Kit signaling affects bone turnover during calcium deprivation. Three-week-old male WBB6F1/J-Kit W /Kit W-v /J (W/W v ) mice with c-Kit point mutation, Kit W-sh /HNihrJaeBsmJ (W sh /W sh ) mice with an inversion mutation in the regulatory elements upstream of the c-Kit promoter region, and their wild-type controls (WT) were fed either a normal (0.6% calcium) or a low calcium diet (0.02% calcium) for 3 weeks. μCT analysis indicated that both mutants fed normal calcium diet had significantly decreased cortical thickness and cancellous bone volume compared to WT. The low calcium diet resulted in a comparable reduction in cortical bone volume and cortical thickness in the W/W v and W sh /W sh mice, and their corresponding controls. As expected, the low calcium diet induced cancellous bone loss in the W/W v mice. In contrast, W sh /W sh cancellous bone did not respond to this diet. This c-Kit mutation prevented cancellous bone loss by antagonizing the low calcium diet-induced increase in osteoblast and osteoclast numbers in the W sh /W sh mice. Gene expression profiling showed that calcium deficiency increased Osx, Ocn, Alp, type I collagen, c-Fms, M-CSF, and RANKL/OPG mRNA expression in controls; however, the W sh mutation suppressed these effects. Our findings indicate that although calcium restriction increased bone turnover, leading to osteopenia, the decreased c-Kit expression levels in the W sh /W sh mice prevented the low calcium diet-induced increase in cancellous bone turnover and bone loss but not the cortical bone loss.

    Full Text Available The present data are related to the article entitled “Insights into ligand stimulation effects on gastro-intestinal stromal tumors signaling” (C. Bahlawane, M. Schmitz, E. Letellier, K. Arumugam, N. Nicot, P.V. Nazarov, S. Haan, 2016 [1]. Constitutive and ligand-derived signaling pathways mediated by KIT and PDGFRA mutated proteins found in gastrointestinal stromal tumors (GIST were compared. Expression of mutant proteins was induced by doxycycline in an isogenic background (Hek293 cells. Kit was identified by FACS at the cell surface and found to be quickly degraded or internalized upon SCF stimulation for both Kit Wild type and Kit mutant counterparts. Investigation of the main activated pathways in GIST unraveled a new feature specific for oncogenic KIT mutants, namely their ability to be further activated by Kit ligand, the stem cell factor (scf. We were also able to identify the MAPK pathway as the most prominent target for a common inhibition of PDGFRA and KIT oncogenic signaling. Western blotting and micro-array analysis were applied to analyze the capacities of the mutant to induce an effective STATs response. Among all Kit mutants, only Kit Ex11 deletion mutant was able to elicit an effective STATs response whereas all PDGFRA were able to do so.

The function of c-Kit has led to the concept that inhibiting c-Kit kinase activity can be a target for cancer therapy. The promising results of inhibition of c-Kit for treatment of cancers have been observed in some cancers such as gastrointestinal stromal tumor, acute myeloid leukemia, melanoma, and other tumors, and these results have encouraged attempts toward improvement of using c-Kit as a capable target for cancer therapy. This paper presents the findings of previous studies regarding c-Kit as a receptor tyrosine kinase and an oncogene, as well as its gene targets and signaling pathways in normal and cancer cells. The c-Kit gene location, protein structure, and the role of c-Kit in normal cell have been discussed. Comprehending the molecular mechanism underlying c-Kit-mediated tumorogenesis is consequently essential and may lead to the identification of future novel drug targets. The potential mechanisms by which c-Kit induces cellular transformation have been described. This study aims to elucidate the function of c-Kit

    This study was conducted to evaluate the prevalence of EGFR and KIT mutations in thymomas and thymic carcinomas as a means of exploring the potential for molecularly targeted therapy with tyrosine kinase inhibitors. Genomic DNA was isolated from 41 paraffin-embedded tumor samples obtained from 24 thymomas and 17 thymic carcinomas. EGFR exons 18, 19, and 21, and KIT exons 9, 11, 13, and 17, were analyzed for mutations by PCR and direct sequencing. Protein expression of EGFR and KIT was evaluated immunohistochemically. EGFR mutations were detected in 2 of 20 thymomas, but not in any of the thymic carcinomas. All of the EGFR mutations detected were missense mutations (L858R and G863D) in exon 21. EGFR protein was expressed in 71% of the thymomas and 53% of the thymic carcinomas. The mutational analysis of KIT revealed only a missense mutation (L576P) in exon 11 of one thymic carcinoma. KIT protein was expressed in 88% of the thymic carcinomas and 0% of the thymomas. The results of this study indicate that EGFR and KIT mutations in thymomas and thymic carcinomas are rare, but that many of the tumors express EGFR or KIT protein.

The purpose of this study was to evaluate the performance of a recently developed domestic immunoradiometric kit for α-fetoprotein (Riakey AFP IRMA CT R , Sin-Jin Medics, Seoul, Korea). We evaluated intra-and inter-assay precision, recovery rate, parallelism, and sensitivity of serum α-fetoprotein measurement using Riakey AFP IRMA CT R kit. The values of α-fetoprotein measured by Riakey AFP IRMA CT R kit were compared with those measured by two foreign commercial kits (α-fetoproteina of Radim and α-feto.riabead of Abbott). Intra-assay coefficients of variation on three different levels were 5.3% for 18.9 ng/ml, 3.4% for 133 ng/ml and 1.6% for 330 ng/ml. Inter-assay coefficients of variation were 9.7% for 20.9 ng/ml, 3.2% for 137 ng/ml and 4.1% for 330 ng/ml respectively. Recovery rate tests on all three different levels showed within 100±10%. Parallelism was also good and the sensitivity was 0.63 ng/ml. There was strong correlation between the measurement of α-fetoprotein by Riakey AFP IRMA CT R and that by two foreign commercial kits(r=3D0.98).

    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)

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

    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

    2006-01-01

    The determination of progesterone concentration in whole and fat-free milk 19-24 days after conception enables to distinguish fertile and non-fertile insemination, which is important in cattle breeding. The aim of this work was to develop a simple and quick radioimmunoassay test for the determination of progesterone in cow milk. Two types of solid-phase tubes coated with specific polyclonal anti-progesterone antibody from ORION Diagnostica and BIOSOURCE International, two different progesterone derivatives viz. progesterone-3- carboxymethyl oxime (CMO) and progesterone-11α-hemisuccinate (HS) conjugated to 125 I-histamine and the HPLC system with Lichrospher RP-18 column along with 65% acetonitrile/water as eluent to purify the tracers were used to carry out this work. Progesterone-3CMO- 125 I-histamine had a retention time of 13.2 min and progesterone-11α-hemisuccinate- 125 I-histamine had a retention time of 7.8 min. Two kinds of kits (kit I and kit II) were prepared, first with progesterone-3CMO- 125 I-histamine as the tracer and coated tubes from Progesterone Veterinary RIA kit of ORION Diagnostica and the second with progesterone-11αHS- 125 I-histamine as the tracer and coated tubes from Progesterone Veterinary RIA kit from BIOSOURCE International. Progesterone from Sigma and selected fat-free cow's milk without progesterone as zero progesterone milk matrix were used for standard preparation. The optimal assay procedure was as follows: 50μL standards, controls and fat-free milk samples were pipetted into coated tubes followed by addition of 500μL of diluted tracer. The tubes were incubated for 2h in case of kit I and 3h for kit II at RT. After the incubation, the tubes were decanted and counted. The assay range was 0 to 270 nmol/L for kit I and 0 to 300 nmol/L for kit II. The sensitivity of the kit with ORION coated tubes was better (0.8 nmol/L) than that of BIOSOURCE tubes which was 1.5 nmol/L. Validation of these assays in terms of specificity, accuracy

    Researchers envisioned Storage as a Service (StaaS) as an effective solution to the distributed management of digital data. Cooperative storage cloud forensic is relatively new and is an under-explored area of research. Using Symform as a case study, we seek to determine the data remnants from the use of cooperative cloud storage services. In particular, we consider both mobile devices and personal computers running various popular operating systems, namely Windows 8.1, Mac OS X Mavericks 10.9.5, Ubuntu 14.04.1 LTS, iOS 7.1.2, and Android KitKat 4.4.4. Potential artefacts recovered during the research include data relating to the installation and uninstallation of the cloud applications, log-in to and log-out from Symform account using the client application, file synchronization as well as their time stamp information. This research contributes to an in-depth understanding of the types of terrestrial artifacts that are likely to remain after the use of cooperative storage cloud on client devices. © 2016 American Academy of Forensic Sciences.

  10. Signaling by Kit protein-tyrosine kinase--the stem cell factor receptor.

    Roskoski, Robert

    2005-11-11

    Signaling by stem cell factor and Kit, its receptor, plays important roles in gametogenesis, hematopoiesis, mast cell development and function, and melanogenesis. Moreover, human and mouse embryonic stem cells express Kit transcripts. Stem cell factor exists as both a soluble and a membrane-bound glycoprotein while Kit is a receptor protein-tyrosine kinase. The complete absence of stem cell factor or Kit is lethal. Deficiencies of either produce defects in red and white blood cell production, hypopigmentation, and sterility. Gain-of-function mutations of Kit are associated with several human neoplasms including acute myelogenous leukemia, gastrointestinal stromal tumors, and mastocytomas. Kit consists of an extracellular domain, a transmembrane segment, a juxtamembrane segment, and a protein kinase domain that contains an insert of about 80 amino acid residues. Binding of stem cell factor to Kit results in receptor dimerization and activation of protein kinase activity. The activated receptor becomes autophosphorylated at tyrosine residues that serve as docking sites for signal transduction molecules containing SH2 domains. The adaptor protein APS, Src family kinases, and Shp2 tyrosyl phosphatase bind to phosphotyrosine 568. Shp1 tyrosyl phosphatase and the adaptor protein Shc bind to phosphotyrosine 570. C-terminal Src kinase homologous kinase and the adaptor Shc bind to both phosphotyrosines 568 and 570. These residues occur in the juxtamembrane segment of Kit. Three residues in the kinase insert domain are phosphorylated and attract the adaptor protein Grb2 (Tyr703), phosphatidylinositol 3-kinase (Tyr721), and phospholipase Cgamma (Tyr730). Phosphotyrosine 900 in the distal kinase domain binds phosphatidylinositol 3-kinase which in turn binds the adaptor protein Crk. Phosphotyrosine 936, also in the distal kinase domain, binds the adaptor proteins APS, Grb2, and Grb7. Kit has the potential to participate in multiple signal transduction pathways as a result of

    2001-10-01

    A large number of microgrippers has been developed in industry and academia. Although the importance of hybrid integration techniques and hence the demand for assembly tools grows continuously a large part of these developments has not yet been used in industrial production. The first grippers developed for microassembly were basically vacuum grippers and downscaled tweezers. Due to increasingly complex assembly tasks more and more functionality such as sensing or additional functions such as adhesive dispensing has been integrated into gripper systems over the last years. Most of these gripper systems are incompatible since there exists no standard interface to the assembly machine and no standard for the internal modules and interfaces. Thus these tools are not easily interchangeable between assembly machines and not easily adaptable to assembly tasks. In order to alleviate this situation a construction kit for modular microgrippers is being developed. It is composed of modules with well defined interfaces that can be combined to build task specific grippers. An abstract model of a microgripper is proposed as a tool to structure the development of the construction kit. The modular concept is illustrated with prototypes.

    Although {alpha}-fetoprotein is one of the most commonly used tumor markers in Korea, most of the radioimmunoassay kits for {alpha}-fetoprotein have been imported from foreign countries. The purpose of this study was to evaluate the performance of a recently developed domestic immunoradiometric kit for {alpha}-fetoprotein (Riakey AFP IRMA CT{sup R}, Sin-Jin Medics, Seoul, Korea). We evaluated intra-and inter-assay precision, recovery rate, parallelism, and sensitivity of serum {alpha}-fetoprotein measurement using Riakey AFP IRMA CT{sup R} kit. The values of {alpha}-fetoprotein measured by Riakey AFP IRMA CT{sup R} kit were compared with those measured by two foreign commercial kits ({alpha}-fetoproteina of Radim and {alpha}-feto.riabead of Abbott). Intra-assay coefficients of variation on three different levels were 5.3% for 18.9 ng/ml, 3.4% for 133 ng/ml and 1.6% for 330 ng/ml. Inter-assay coefficients of variation were 9.7% for 20.9 ng/ml, 3.2% for 137 ng/ml and 4.1% for 330 ng/ml respectively. Recovery rate tests on all three different levels showed within 100{+-}10%. Parallelism was also good and the sensitivity was 0.63 ng/ml. There was strong correlation between the measurement of {alpha}-fetoprotein by Riakey AFP IRMA CT{sup R} and that by two foreign commercial kits(r=3D0.98). The first Korean domestic immunoradiometric kit for {alpha}-fetoprotein, Riakey AFP IRMA CT{sup R}, performed well for clinical use.

    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 standardization of kit components and assay methods is desirable in order to allow comparison of results between laboratories using different kits.

    Smyth, D.R.; Tsopelas, C.

    2005-01-01

    Aprotinin is a small protein that inhibits serine proteases and has been shown to bind to amyloid fibrils of varying chemical composition in-vitro. 99 mTc-aprotinin has demonstrated potential for imaging cardiac and pleuropulmonary AL amyloidosis and other forms of amyloidosis present as deposits in joints, the tongue or intestines and other sites excluding the kidneys and liver. Radiolabelling of aprotinin was previously achieved by addition of 99 mTc-pertech-netate to an alkaline mixture of Trasylol (aprotinin injection) and stannous chloride, followed by a necessary filtration step after 20-30 minutes. We have developed a modified cold kit formulation, utilising pharmaceutical starting materials, that provides a more convenient and efficient radiolabelling procedure where filtration is not required prior to injection. The shelf life of the cold kits was validated after storage in a freezer. The reducing agent used was stannous-pyrophosphate (PYP) and the alkaline buffer was a phosphate-glycine mixture (pH 10.5). Quality control testing of the cold kits was performed after 0, 1, 2, 3 and 6 months storage by assessing the % RCP of 99 mTc-apro-tinin by ITLC-SG. Radiotracer stability was examined in the same way 25, 85 and 265 minutes post reconstitution (pr) via a three strip system employing acetone, saline and ammonia:ethanol:water mixture (1:2:5). A rapid quality control cartridge method was also investigated. Radiolabelling of the cold kits yielded RCP > 95% at 25 mins pr and all other time points, from a formulation that avoided a filtration step. The impurities were quantified as TcO., ( 99 mTc-PYP (< 0.7%) by paper methods. The improved Tc-aprotinin kit formulation has greater convenience and efficiency in the clinical setting

  19. Oncogenic activation of v-kit involves deletion of a putative tyrosine-substrate interaction site.

    Herbst, R; Munemitsu, S; Ullrich, A

    1995-01-19

    The transforming gene of the Hardy-Zuckerman-4 strain of feline sarcoma virus, v-kit, arose by transduction of the cellular c-kit gene, which encodes the receptor tyrosine kinase (RTK) p145c-kit. To gain insight into the molecular basis of the v-kit transforming potential, we characterized the feline c-kit by cDNA cloning. Comparison of the feline v-kit and c-kit sequences revealed, in addition to deletions of the extracellular and transmembrane domains, three additional mutations in the v-kit oncogene product: deletion of tyrosine-569 and valine-570, the exchange of aspartate at position 761 to glycine, and replacement of the C-terminal 50 amino acids by five unrelated residues. Examinations of individual v-kit mutations in the context of chimeric receptors yielded inhibitory effects for some mutants on both autophosphorylation and substrate phosphorylation functions. In contrast, deletion of tyrosine-569 and valine-570 significantly enhanced transforming and mitogenic activities of p145c-kit, while the other mutations had no significant effects. Conservation in subclass III RTKs and the identification of the corresponding residue in beta PDGF-R, Y579, as a binding site for src family tyrosine kinases suggests an important role for Y568 in kit signal regulation and the definition of its oncogenic potential. Repositioning of Y571 by an inframe two codon deletion may be the crucial alteration resulting in enhancement of v-kit oncogenic activity.

    Raviv, Ayala; Cohen, Sarit; Aflalo, Ester

    2017-07-01

    Despite the inherent potential of cooperative learning, there has been very little research into its effectiveness in middle school laboratory classes. This study focuses on an empirical comparison between cooperative learning and individual learning in the school science laboratory, evaluating the quality of learning and the students' attitudes. The research included 67 seventh-grade students who undertook four laboratory experiments on the subject of "volume measuring skills." Each student engaged both in individual and cooperative learning in the laboratory, and the students wrote individual or group reports, accordingly. A total of 133 experiment reports were evaluated, 108 of which also underwent textual analysis. The findings show that the group reports were superior, both in terms of understanding the concept of "volume" and in terms of acquiring skills for measuring volume. The students' attitudes results were statistically significant and demonstrated that they preferred cooperative learning in the laboratory. These findings demonstrate that science teachers should be encouraged to implement cooperative learning in the laboratory. This will enable them to improve the quality and efficiency of laboratory learning while using a smaller number of experimental kits. Saving these expenditures, together with the possibility to teach a larger number of students simultaneously in the laboratory, will enable greater exposure to learning in the school science laboratory.

    The aim of this work was to prepare a kit of 99 m Tc-ceftizoxime ( 99m Tc-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/m L). After lyophilization, the kit was reconstituted with 1.0 mL of sodium 99m Tc pertechnetate solution (Na 99m Tc O 4- ) 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 99m Tc-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 99m Tc-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 99 m Tc-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 99m Tc-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 ( 99m Tc-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. (author)

    To explain the evolutionary emergence of uniquely human skills and motivations for cooperation, Tomasello et al. (2012, in Current Anthropology 53(6):673-92) proposed the interdependence hypothesis. The key adaptive context in this account was the obligate collaborative foraging of early human adults. Hawkes (2014, in Human Nature 25(1):28-48), following Hrdy (Mothers and Others, Harvard University Press, 2009), provided an alternative account for the emergence of uniquely human cooperative skills in which the key was early human infants' attempts to solicit care and attention from adults in a cooperative breeding context. Here we attempt to reconcile these two accounts. Our composite account accepts Hrdy's and Hawkes's contention that the extremely early emergence of human infants' cooperative skills suggests an important role for cooperative breeding as adaptive context, perhaps in early Homo. But our account also insists that human cooperation goes well beyond these nascent skills to include such things as the communicative and cultural conventions, norms, and institutions created by later Homo and early modern humans to deal with adult problems of social coordination. As part of this account we hypothesize how each of the main stages of human ontogeny (infancy, childhood, adolescence) was transformed during evolution both by infants' cooperative skills "migrating up" in age and by adults' cooperative skills "migrating down" in age.

    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...... thermoregulatory response to the L temperature by increased HE, whereas groups of kits showed increased HE from 29th day onwards. 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....... 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...

  6. The need for standardization of methodology and components in commercial radioimmunoassay kits

    The problems arising from the increasing use of commercial kits in radioimmunoassay (RIA) and related fields are discussed. These problems differ according to the substance under test. The quality of individual reagents is often good, but the methodology is often not optimal and may contain short-cuts which, although commercially attractive, can lead to erroneous values and poor sensitivity and precision. Minor modifications in the methodology often lead to big improvements in sensitivity and precision. This has been demonstrated in three digoxin kits employing antibody-coated tube techniques and in four kits for thyrotropin (TSH) using different techniques. It has also been noted that with many quality-control sera imported from the USA no values are ascribed to European kits for the components listed, thus reducing these sera to the function of precision control. The study underlines the need to standardize kit components and assay methods to enable the results obtained by different laboratories with different kits to be compared. (author)

    This study developed a modified pre tinning method for labeling erythrocytes with technetium-99m in vitro using a kit which contains stannous chloride stabilized with geneticist acid (GA) in lyophilized form. This GA-kit a sterile closed system that does not require centrifugation,washing and separation of the RBCs. The kit is simple to use and labeling takes ∼ 30 min with a typical labeling efficiency of 97.3% ± 1.2% for 60 determinations. Imaging studies were performed in rabbit using GA-kit in vitro labeling procedure and PYP-kit in vivo labeling. It shows that the heart-to-background ratio with GA in vitro labeling were significantly higher than with in vivo labeling. Leukocytes labeling with technetium-99m using the same GA kit also was studied. The labeling efficiency was 20 ∼ 41%. Thus, the GA kit is versatile and cost-effective.

    Germline mutations at the Dominant White Spotting (W) and Steel (Sl) loci have provided conclusive genetic evidence that c-kit mediated signal transduction pathways are essential for normal mouse development. We have analysed the interactions of normal and mutant W/c-kit gene products with cytoplasmic signalling proteins, using transient c-kit expression assays in COS cells. In addition to the previously identified c-kit gene product (Kit+), a second normal Kit isoform (KitA+) containing an in-frame insertion, Gly-Asn-Asn-Lys, within the extracellular domain, was detected in murine mast cell cultures and mid-gestation placenta. Both Kit+ and KitA+ isoforms showed increased autophosphorylation and enhanced association with phosphatidylinositol (PI) 3' kinase and PLC gamma 1, when stimulated with recombinant soluble Steel factor. No association or increase in phosphorylation of GAP and two GAP-associated proteins, p62 and p190, was observed. The two isoforms had distinct activities in the absence of exogenous soluble Steel factor; Kit+, but not KitA+, showed constitutive tyrosine phosphorylation that was accompanied by a low constitutive level of association with PI-3' kinase and PLC gamma 1. Introduction of the point substitutions associated with W37 (Glu582----Lys) or W41 (Val831----Met) mutant alleles into c-kit expression constructs abolished (W37) or reduced (W41) the Steel factor-induced association of the Kit receptor with signalling proteins in a manner proportional to the overall severity of the corresponding W mutant phenotype. These data suggest a diversity of normal Kit signalling pathways and indicate that W mutant phenotypes result from primary defects in the Kit receptor that affect its interaction with cytoplasmic signalling proteins.

    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.

    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.

    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

    2015-11-01

    The authors have designed and prototyped an educational toolkit that will help middle-school-aged students learn fundamental fluid mechanics and heat transfer concepts in a hands-on play environment. The kit allows kids to build arbitrary flow rigs to solve fluid mechanics and heat transfer challenge problems. Similar kits for other engineering fields, such as structural and electrical engineering, have resulted in pedagogical improvements, particularly in early engineering education, where visual demonstrations have a significant impact. Using the FlowGo kit, students will be able to conduct experiments and develop new design ideas to solve challenge problems such as building plant watering systems or modeling water and sewage reticulation. The toolkit consists of components such as tubes, junctions, and reservoirs that easily snap together via a modular, universal connector. Designed with the Massachusetts K-12 science standards in mind, this kit is intended to be affordable and suitable for classroom use. Results and user feedback from students conducting preliminary tests of the kit will be presented.

  19. An evaluation of chemical screening test kits for lead in paint

    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.

  20. 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 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.

    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.

    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. Graphical abstract 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. In this study, we compared four commonly used commercially available kits for exosomal mi

    2009-01-01

    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.

  7. Determination of stannous tin in radiopharmaceutical cold kits

    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

    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.

    Pressure-transducer kits have frequency characteristics such as natural frequency and damping coefficient, which affect the monitoring accuracy. The aim of the present study was to investigate the effect of planecta ports and a damping device (ROSE™, Argon Medical Devices, TX, USA) on the frequency characteristics of pressure-transducer kits. The FloTrac sensor kit (Edwards Lifesciences, CA, USA) and the DTXplus transducer kit (Argon Medical Devices) were prepared with planecta ports, and their frequency characteristics were tested with or without ROSE™. The natural frequency and damping coefficient of each kit were obtained using frequency characteristics analysis software and evaluated by plotting them on the Gardner's chart. By inserting a planecta port, the natural frequency markedly decreased in both the FloTrac sensor kit (from 40 to 22 Hz) and the DTXplus transducer kit (from 35 to 22 Hz). In both kits with one planecta port, the damping coefficient markedly increased by insertion of ROSE™ from 0.2 to 0.5, optimising frequency characteristics. In both kits with two planecta ports, however, the natural frequency decreased from 22 to 12 Hz. The damping coefficient increased from 0.2 to 0.8 by insertion of ROSE™; however, optimisation was not achieved even by ROSE™ insertion. Planecta ports decrease the natural frequency of the kit. ROSE™ is useful to optimise the frequency characteristics in the kits without or with one planecta port. However, optimisation is difficult with two or more planecta ports, even with the ROSE™ device.

    To explore the views of New Zealand pharmacists on bowel cancer screening, particularly with regards to faecal occult blood testing (FOBT) kits, self-perceived knowledge on FOBT kits and barriers, motivators and experiences with selling and counselling consumers with respect to FOBT kits. Semi-structured interviews were conducted face to face or by telephone with 20 community pharmacists in the Auckland region. Interviews were recorded and transcribed verbatim and data were coded and analysed using NVivo software to identify key themes. Participant pharmacists believed that they were well placed to provide advice on FOBT kits to consumers. Barriers to selling the kits included cost and perceived lack of test sensitivity of the kits, poor consumer demand, pharmacists' lack of training and information, and a belief that selling FOBT kits was outside the pharmacists' scope of practice. Motivators to selling the kits included customer convenience, ease of use, confidence in the kits and embracing new roles for pharmacists. Pharmacists were concerned that use of the kits may increase the burden on the public health system through customer anxiety over test results; however, they agreed that there was a need for bowel cancer screening and awareness and that people concerned about bowel cancer should make visiting their general practitioner a priority. Pharmacists' views were mixed. Pharmacists' training and competence with respect to the provision of bowel cancer kits, and how a bowel cancer screening service can be developed to optimise public health outcomes, need to be addressed. © 2013 Royal Pharmaceutical Society.

  11. The need for standardisation of methodology and components in commercial radioimmunoassay kits

    International Nuclear Information System (INIS)

    1977-01-01

    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.)

    1985-01-01

    A computerized quality assurance kit to provide precise measurement and calibration of microwave power and temperature, as well as capabilities to map SAR (Specific absorption rate) distribution in phantoms; and survey of hazardous microwave leakage has been designed. The kit is also capable of performing corelation studies on the relationship between SAR and net microwave power delivered at various anatomical sites. The kit consists of a portable microcomputer, a time-multiplexed A/D converter, a 4-channel dual directional microwave power monitor, a 4-channel thin-wire thermocouple thermometry system, an electronic thermal calibrator, a microwave leakage hazard survey meter, and a dynamic phantom tank for dosimetric analysis. Comparative performance studies were made against NBS-traceable power and temperature standards, non-perturbing optical temperature sensors, and established power and temperature measurement devices. The test results indicate that this instrument is providing its user with measurement accuracy of 0.1 0 C in temperature, 10% accuracy in power. The thin-wire thermocouple, with computer assisted error compensation, performs equally well in a strong microwave field in comparison with non-perturbing optical temperature sensors

    The aim of this work was to prepare a kit of {sup 99}m Tc-ceftizoxime ({sup 99m} Tc-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/m L). After lyophilization, the kit was reconstituted with 1.0 mL of sodium {sup 99m} Tc pertechnetate solution (Na {sup 99m} Tc O{sub 4-}) 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 {sup 99m} Tc-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 {sup 99m} Tc-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 {sup 99}m Tc-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 {sup 99m} Tc-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 ({sup 99m} Tc-CFT) by the infectious site during the experiment. The results attest to the viability of producing a kit with {sup 99m} technetium-labeled ceftizoxime for the

    2015-01-01

    To describe and evaluate disposable saliva collection kit for rapid, reliable, and reproducible collection of saliva samples. The saliva collection kit comprised of a saliva absorbent swab and an extractor unit was used to retrieve whole saliva samples from 10 subjects. The accuracy and precision of the extracted volumes (3, 10, and 30 μl) were compared to similar volumes drawn from control samples obtained by passive drool. Additionally, the impact of kit collection method on subsequent immunoassay results was verified by assessing salivary cortisol levels in the samples and comparing them to controls. The recovered volumes for the whole saliva samples were 3.85 ± 0.28, 10.79 ± 0.95, and 31.18 ± 1.72 μl, respectively (CV = 8.76%) and 2.91 ± 0.19, 9.75 ± 0.43, and 29.64 ± 0.91 μl, respectively, (CV = 6.36%) for the controls. There was a close correspondence between the salivary cortisol levels from the saliva samples obtained by the collection kit and the controls (R(2)  > 0.96). The disposable saliva collection kit allows accurate and repeatable collection of fixed amounts of whole saliva and does not interfere with subsequent measurements of salivary cortisol. The simple collection process, lack of elaborate specimen recovery steps, and the short turnaround time (<3 min) should render the kit attractive to test subjects and researchers alike. © 2015 Wiley Periodicals, Inc.

    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.

    Blight, L.F.; White, G.H.

    1983-01-01

    We have evaluated two commercially available 125 I radioimmunoassay kits (Diagnostic Products Corp., DPC; and Radioassay Systems Laboratories, RSL) for measurement of serum or plasma progesterone, to determine their suitability for use in in vitro fertilization programs. Both kits were suitably rapid for program requirements. Results by both were linear with concentration up to 60 nmol/L, and both had acceptable lower detection limits of 0.3 nmol/L. Kit-determined progesterone concentrations (y) for 100 patients' samples correlated well with results by our existing 3H radioimmunoassay method (y . 1.11x + 0.2, r . 0.965 for the DPC kit; y . 1.01x + 1.4, r . 0.974 for the RSL kit). Mean analytical recovery for the RSL kit was 116%, that for the DPC kit, 202%. Within-batch precision, expressed as the mean CV for three concentrations of progesterone, was 6.5% for the RSL kit, and 16.4% for the DPC kit; between-day CV was 8.1% for the RSL kit, 17.7% for the DPC kit. We conclude that the RSL kit provides a rapid, precise, and accurate assay for serum progesterone, suitable for use in a fertilization program, but do not recommend the DPC kit for either this purpose or the more general purpose of tracking menstrual cycles

  2. Determination of Sn in 99mTc Radiopharmaceutical Kits by Polarographic Methods

    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.

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

    Directory of Open Access Journals (Sweden)

    Marcin Wysoczynski

    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.

    We are examining a variety of telescope kits suitable for assembly by school-age children in order to design a cornerstone educational program for the International Year of Astronomy 2009-400 years after Galileo's observations. In our experience, telescope kits are superior to pre-assembled telescopes for use in an educational setting as the students feels a stronger sense of ownership and have a better understanding of the components and how they work. We examined several low to medium power refracting telescope kits including one kit used in the Hands-On Optics project at NOAO. We describe the advantages and disadvantages of each kit from an educational and optical perspective and what modifications may be made to enhance their educational utility. We also describe the optical and education requirements for a low-powered "Galileoscope", to be distributed widely during the IYA. We also describe how the "Galileoscope” will be embedded in an educational program disseminated through science centers, amateur astronomy clubs and other Hands-On Optics centers and partners.

    1997-01-01

    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

    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)

    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

    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 aim was to determine the performances of four Helicobacter pylori serological detection kits in different target groups, using Amplified IDEIA™ Hp StAR™ as gold standard. Kits studied were Rapid Immunochromatoghraphic Hexagon, Helicoblot 2.1, an EIA IgG kit and EIA IgA kit. Stool and blood samples were collected from 162 apparently healthy participants (control) and 60 Type 2 diabetes mellitus (T2DM) patients. The performances of the four serological detection kits were found to be affected by gender, age, health status and ethnicity of the participants. In the control group, the Helicoblot 2.1 kit had the best performance (AUC = 0.85; ppoor performances. In the T2DM subgroup, the kits H2.1 and EIA IgG had best performances, with accuracies of 96.5% and 93.1% respectively. The performance of EIA IgG improved with adjustment of its cut-off value. The performances of the detection kits were affected by various factors which should be taken into consideration.

    2010-09-01

    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.

    The safe decommissioning of nuclear installations is technically feasible, but is also still a challenge for science, technology and industry. The expertise and know how for decommissioning must be ensured because it will be needed for further decades. Already in 2008 the Karlsruhe Institute of Technology (KIT) had identified this challenge that later emerged through the closure of nuclear power plants in Germany. The KIT opened the professorship Technology and Management of the Decommissioning of Nuclear Installations. In 2014, this section was extended through the dismantling of conventional installations.

    'DPC RIA' kits for measuring free triiodothyronine (T3) and free thyroxine (T4) were fundamentally and clinically studied. Standard curves for incubation temperature and time were favorable. The present kits yielded satisfactory precision and reproducibility. The upper and lower limits of the normal range for T4 were 0.88 ng/dl and 2.08 ng/dl, respectively. The serum concentration of T4 was 3.91 ng/dl or more for hyperthyroidism and 0.57 ng/dl or less for hypothyroidism, allowing discrimination between the two diseases. For T3, the upper and lower limits of the normal range were 1.45 ng/dl and 3.45 ng/dl, respectively. In pregnant women and patients with decreased or increased levels of thyroxine binding globulin (TBG), the serum T3 concentration lay within the normal range. Low free T4 and T3 levels were found in 22 % and 67 %, respectively, of patients with serious non-thyroidal illness (NTI). There was a good correlation between the present kits and the other commercially available kits. Measurements of free T3 and T4 obtained by ''Amerlex RIA'' kits tended to be lower than those by the present kits in pregnant women and NTI patients with hypoalbuminemia. In view of the simplified procedure, satisfactory precision and reproducibility, and the lack of influences of serum albumin and TBG, the present kits have a potential in routine use. (Namekawa, K.)

    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

    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

    Eliyahu, Ayala

    2015-06-01

    Full Text Available The philosophical treatise known as Kitāb al-ḥadā’iq is generally ascribed to the 12th century Andalusian author Ibn al-Sīd al-Batalyawsī, although this attribution is sometimes contested. This paper offers a new interpretation of the title, textual history, authorship, sources, and literary genre of this treatise, on the basis of new textual evidence, a reexamination of known evidence, and a comparison between the treatise and Batalyawsī’s works. The conclusions of this study are first, that Kitāb al-ḥadā’iq was not the treatise’s original title, and therefore it should be renamed Kitāb al-dawā’ir; second, that Kitāb al-dawā’ir was originally part of (one of the versions of Batalyawsī’s Kitāb al-masā’il; and third, that the textual and stylistic similarities between this treatise and Batalyawsī’s other works prove the authenticity of the treatise’s attribution to Batalyawsī. In addition, new findings regarding Batalyawsī’s use of formulas from the Rasā’il Ikhwān al-Safā, in Kitāb al-dawā’ir and Kitāb al-masā’il provide further evidence for the deep impact of the Ikhwān on Batalyawsī’s thought, as well as for the close connection between Kitāb al-dawā’ir and Kitāb al-masā’il. This connection is further highlighted according to the attribution of both treatises to the genre of questions and answers in Arabic literature. The evidence gathered in this paper supports the claim that Batalyawsī’s Kitāb al-dawā’ir should be seen as an integral part of his literary oeuvre, as well as of Andalusian philosophical literature in general.Generalmente el tratado filosófico conocido como Kitāb al-ḥadā’iq se asocia al autor andalusí del siglo XII Ibn al-Sid al-Batalyawsī, aunque esta atribución ha sido discutida en ocasiones.

    2005-01-01

    This study describes the development of the behaviour of mink kits and dams from the fourth to the eighth respectively seventh week after delivery. The study is based on scan observations of 72 mink dams and their kits at a conventional Danish mink farm. The kits started eating when they were about...... 30 d old. Drinking started almost 2 wk later. During these 2 wk there was a peak in the licking of saliva from the dam and of the inter-litter agonistic behaviour. A causal relationship between experienced thirst and agonistic behaviour is suggested. The kits' sucking declined to only 5% of the time...... budget in the seventh week and the stereotypy frequency of the dams increased to about 4% of the time budget. It is suggested that some dams are frustrated by the forced cohabitation with their nutritionally independent kits already in the seventh week and that this should be taken into account when...

    The biochemical laboratory compared the following diagnostic kits for HPL determination: Pharmacia (Sweden), Radiochemical Center Amersham (GB), NEN (USA), Hoechst (FRG), applying the following criteria: 1. price, 2. number of analyses for which one kit may be applied, 3. expiration time, 4. speed, i.e., time elapsed from sample delivery to report (dependent on incubation time), 5. laboriousness, 6. reproducibility, 7. compatibility of values obtained by different kits. Alcohol precipitation (Pharmacia, RCC Amersham) appeared to be the most suitable while Dextran coated charcoal (NEN) and Amberlite (Hoechst) were somewhat more complicated, and the Sorin double antibody technique (ultrafiltration and washing of precipitate on filtres was used for separation) appeared to be the most laborious technique. RCC Amersham was ranked first owing to its lower cost as compared with runner-up Pharmacia. (L.O.)

    Full Text Available In this paper, we will present the impact of the conical shape of a pressing chamber, an important structural parameter. Besides the known impact of the technological parameters of pressing chambers, it is also very important to pay attention to their structural parameters. In the introduction, we present a theoretical analysis of pressing chamber conicalness. An experiment aimed at detecting this impact was performed at our institute, and it showed that increasing the conicalness of a pressing chamber improves the quality of the final briquettes. The conicalness of the pressing chamber has a significanteffect on the final briquette quality and on the construction of briquetting machines. The experimental findings presented here show the importance of this parameter in the briquetting process.

  11. France Electricity Report for 2014 - Press kit

    2015-01-01

    In compliance with the remits assigned to it by the legislator, every year RTE publishes the electricity report, which provides an overview of the power system for the past year (trends in electricity consumption and generation, power mix, level of market prices, extent of French electricity exports and imports, etc). French electricity consumption fell by 6% in 2014 according to raw data, given the extremely mild weather, and by 0.4% after adjustment for weather contingencies. Renewable energies continued to be developed and accounted for nearly 20% of French electricity consumption. The decrease in electricity consumption in 2014, combined with the boost of renewable energies, enabled CO 2 emissions in the power sector to be further reduced by 40%. With a positive trade balance of 65 TWh, France remained the leading electricity exporter in Europe. Due to the mildness of the weather (2014 was the hottest year since the beginning of the 20. century), gross electricity consumption fell by 6% against 2013, to 465.3 TWh. Adjusted for weather contingencies, French electricity consumption decreased by 0.4%. For the first time, SME-SMI, professional and private consumption also fell by 0.5% (392.4 TWh), while large-scale industrial consumption remained stable (67.4 TWh). This slight drop in electricity consumption not only reflected the economic slowdown but also the effect of energy saving measures deployed in France over the past few years. In 2014, renewable energies (including hydropower) accounted for nearly 20% of French electricity consumption, mirroring 2013 with albeit one difference: renewable energy generation, excluding hydropower, outperformed the fossil fuel share, with 28 TWh of electricity generated. Clarification of the regulatory framework and more favourable economic provisions in 2014 fostered an increase of nearly 1,900 MW in wind power and photovoltaic power generation capacities, with installed capacity of wind power of more than 9,100 MW and that of photovoltaic power of nearly 5,300 MW. Generation capacity of the coal-fired power plants, several of which have been shut down, plummeted by 58%. With gas-fired plants being deployed less (-28%), and given the weather conditions not being conducive to the use of these means of generation, fossil fuel power generation fell by 17.7 TWh (-40%). The drop in consumption, combined with the boom in renewable energies and decreased fossil fuel power generation meant that greenhouse gas emissions were reduced by more than 40% in the electricity sector, with 19 million tonnes of CO 2 equivalent. Electricity trades were especially sustained in 2014 (92.4 TWh exported and 27.3 TWh imported). With a positive trade balance of 65.1 TWh in 2014, France remained the leading electricity exporter in Europe. Due to unavailability of virtually half of the Belgian nuclear fleet, 16.5 TWh of electricity was exported to Belgium (+28% against 2013). Sustained use of the interconnections especially confirmed the need to continue to adapt the power grid so that it can achieve the aims of energy transition embarked upon in France and in Europe. In order to contribute to this initiative and enable customers to receive clean, safe and cost-effective electricity, in 2014, RTE upheld its level of investment at Meuros 1,374, roughly the same amount as in 2013. All this information on consumption, generation, cross-border exchanges and CO 2 emissions can be consulted in real time on the new version of the general public application, eco2mix, available on smart phones, tablet computers and the RTE web site

    A new 'same-day' TSH-RIA kit has been tested against an 'in-house' TSH-RIA, using incubation schemes of 4, 22 and 23 h. The kit standards were made up in human TSH-free serum and the method used a preincubation step and separation of bound and free antigen using a double antibody method. The correlation between the 'in-house' method and the kit was very good. The results in sera from TRH-test patients, and also from a recovery test with MRC 68/38 in human serum covering the range 0-50 mU/l were good. A comparison of the new kit was made with its precedessor which had protein based standards highlighted the need for standards in human TSH-free serum seen by the poor correlation (r = 0.619, n = 93).

    2011-05-01

    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.

Kits studied were Rapid Immunochromatoghraphic Hexagon, Helicoblot 2.1, an EIA IgG kit and EIA IgA kit.Stool and blood samples were collected from 162 apparently healthy participants (control and 60 Type 2 diabetes mellitus (T2DM patients.The performances of the four serological detection kits were found to be affected by gender, age, health status and ethnicity of the participants. In the control group, the Helicoblot 2.1 kit had the best performance (AUC = 0.85; p<0.05, accuracy = 86.4%, followed by EIA IgG (AUC = 0.75; p<0.05, accuracy = 75.2%. The Rapid Hexagon and EIA IgA kits had relatively poor performances. In the T2DM subgroup, the kits H2.1 and EIA IgG had best performances, with accuracies of 96.5% and 93.1% respectively. The performance of EIA IgG improved with adjustment of its cut-off value.The performances of the detection kits were affected by various factors which should be taken into consideration.

    2008-09-01

    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.

    Various experiments for the quality control of Tc-99m labelled radiopharmaceuticals such as Tc-99m-phytate, Tc-99m-MDP, Tc-99m-Tin Colloid, Tc-99m-DISIDA, Tc-99m-DTPA,Tc-99m-DMSA, Tc-99m-Gulcoheptonate, TC-99m-Pyrophosphate, Tc-99m-HSA, and Tc-99m-HAM were carried out. Labelling yield and radiochemical purity of each of the instant labelling kit of KAERI made were determined by means of radiochromatography. Biodistribution in mice and whole body or specific organ imagings of rabbits were also carried out and discussed the relationship between the data of biodistributions and radiochemical purities. Labelling yeilds were above 98% for almost all of the labelling kits. The radio-pharmaceuticals were accumulated at each target organ with moderate specifities. In case of radiochemical purity of above 98%, the biodistribution and gamma imagings were also better. The kits of MDP and DISIDA were stable at least for four moths while the other kits at least eight months. (Author)

    Full text: Myoview is a freeze-dried ethylene diphosphine ligand that upon reconstitution with 99 Tc m -pertechnetate yields a preparation containing the lipophilic cationic myocardial imaging agent 99 Tc m -tetrofosmin (Tf). The aim of this study was to determine the feasibility of fractionating Myoview kits to reduce the cost of the kit, currently A$350 per vial. Myoview vials were reconstituted with N 2 -flushed saline and split into 4 or 5 aliquots of 0.5 ml, then stored at -80 deg C in N 2 -filled vials for up to 3 months. 99 Tc m -Tf was prepared by the addition of varying volumes of 99 Tc m -pertechnetate (1.1 GBq.ml- 1 ) to give a final ligand concentration of 14.4 μg.ml- 1 , followed by a 15 min incubation at room temperature. Radiochemical purity (RCP) was examined at 0, 1, 2 and 3 months post-fractionation. At each time point, RCP was determined at 0,1, 2, 4, 6 and 24 h post-reconstitution. RCP was measured using the thin layer chromatography method according to the manufacturer's instructions. Over the 3 month evaluation period, RCP was maintained at 96.4 ± 1.7% (n = 48) over 24 h at room temperature. Animal biodistribution studies were used to validate the final product from the full cold kit to that from the fractionated kits. In conclusion, these results show that Myoview kits can be successfully fractionated and stored for up to 3 months. The subsequent 99 Tc m -Tf can be used to provide significant cost reductions, especially when only 1 patient dose is required

    Gastrointestinal stromal tumors (GISTs) are specific KIT expressing and KIT-signaling driven mesenchymal tumors of the human digestive tract, many of which have KIT-activating mutations. Previous studies have found a relatively homogeneous gene expression profile in GIST, as compared with other histological types of sarcomas. Transcriptional heterogeneity within clinically or molecularly defined subsets of GISTs has not been previously reported. We tested the hypothesis that the gene expression profile in GISTs might be related to KIT genotype and possibly to other clinicopathological factors. An HG-U133A Affymetrix chip (22,000 genes) platform was used to determine the variability of gene expression in 28 KIT-expressing GIST samples from 24 patients. A control group of six intra-abdominal leiomyosarcomas was also included for comparison. Statistical analyses (t tests) were performed to identify discriminatory gene lists among various GIST subgroups. The levels of expression of various GIST subsets were also linked to a modified version of the growth factor/KIT signaling pathway to analyze differences at various steps in signal transduction. Genes involved in KIT signaling were differentially expressed among wild-type and mutant GISTs. High gene expression of potential drug targets, such as VEGF, MCSF, and BCL2 in the wild-type group, and Mesothelin in exon 9 GISTs were found. There was a striking difference in gene expression between stomach and small bowel GISTs. This finding was validated in four separate tumors, two gastric and two intestinal, from a patient with familial GIST with a germ-line KIT W557R substitution. GISTs have heterogeneous gene expression depending on KIT genotype and tumor location, which is seen at both the genomic level and the KIT signaling pathway in particular. These findings may explain their variable clinical behavior and response to therapy.

    2008-01-01

    Although primarily required for the growth, differentiation, and survival of mast cells, Kit ligand (stem cell factor) is also required for optimal antigen-mediated mast cell activation. Therefore, concurrent inhibition of Kit- and FcepsilonRI-mediated signaling would be an attractive approach...... characterized Kit inhibitor imatinib mesylate (imatinib). In contrast to imatinib, however, hypothemycin also effectively inhibited FcepsilonRI-mediated degranulation and cytokine production in addition to the potentiation of these responses via Kit. The effect of hypothemycin on Kit-mediated responses could...... be explained by its inhibition of Kit kinase activity, whereas the inhibitory effects on FcepsilonRI-dependent signaling were at the level of Btk activation. Because hypothemycin also significantly reduced the mouse passive cutaneous anaphylaxis response in vivo, these data provide proof of principle...

    The T/sub 4/ RIA kit is based on single antibody radioimmunoassay and utilizes a resin-sponge to separate free T/sub 4/-/sup 125/I from the incubation mixture. The use of the sodium salt of trichloroacetic acid (TBG inhibitor) permits direct radioimmunoassay of T/sub 4/ without a tedious extraction procedure. The T/sub 4/ RIA kit needs only 0.05 ml of patient serum and one hour of incubation to measure T/sub 4/. The TBG inhibitior was equivalent to 5.1 ..mu..g% of T/sub 4/ in displacing radioactive T/sub 4/ from TBG in a CPBA(Res-O-Mat T/sub 4/) system, and the TBG inhibitor volume of 0.5 ml (ten times of serum) was needed to measure a high T/sub 4/ concentration serum. The change of incubation temperature was more affected on the standard curve than that of incubation time. Correlation of the T/sub 4/ value between radioimmunoassay and CPBA in 69 patients was good (r=0.88612, p<0.01) and showed a slightly higher T/sub 4/ value when measured with radioimmunoassay than CPBA (linear regression function: Y=1.17506 + 0.95766X). Correlation of T/sub 4/ between Compu-curve and conventional standard curve was excellent (r=0.9995), but a slight difference was found in both low and high T/sub 4/ concentrations. In euthyroid patients without thyroid diseases, T/sub 4/ concentration was 9.92 +- 2.66 (SD) ..mu..g% and the normal range was between 4.60 and 15.24 ..mu..g%. Reproducibility within assay was 9.9% (CV) and recovery rate was 70% when added 10 ..mu..g of T/sub 4/ and 86% when added 15 ..mu..g% of T/sub 4/. From these results, the authors concluded that radioimmunoassay of serum T/sub 4/ using the T/sub 4/ RIA kit would be a promising one, especially when measuring a large amount of samples per assays.

    2012-01-01

    Several DNA extraction methods have been officially introduced to detect genetically modified soybeans, but the choice of DNA extraction kits depend on the nature of the samples, such as grains or processed foods. To overcome this disadvantage, we examined whether the GM quicker kit is available for both grains and processed foods. We compared GM quicker with four approved DNA extraction kits in respect of DNA purity, copy numbers of lectin gene, and working time. We found that the DNA quality of GM quicker was superior to that of the other kits for grains, and the procedure was faster. However, in the case of processed foods, GM quicker was not superior to the other kits. We therefore investigated an unapproved GM quicker 3 kit, which is available for DNA extraction from processed foods, such as tofu and boiled soybeans. The GM quicker 3 kit provided good DNA quality from both grains and processed foods, so we made a minor modification of the GM quicker-based protocol that was suitable for processed foods, using GM quicker and its reagents. The modified method enhanced the performance of GM quicker with processed foods. We believe that GM quicker with the modified protocol is an excellent tool to obtain high-quality DNA from grains and processed foods for detection of genetically modified soybeans.

    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 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

    Well-equipped first-aid kits are necessary but not always provided on recreational dive boats. We aimed to review the types of illness and injury likely to be encountered on such boats and inform a content list for such kits. We conducted a 3-round Delphi study by email using a volunteer panel of 18 experts drawn from diving, dive medicine and nursing. In round 1, panellists shared examples of illnesses and injuries they had come across personally. These scenarios were circulated along with findings from a literature review, including existing recommendations. In rounds 2 and 3, the list of kit for dive boats in different settings was iteratively refined through online discussion and feedback. Passengers and crew on recreational dive boats may encounter a range of medical problems from minor injuries to serious accidents and non-dive-related illnesses. Recommended kit varied depending on context and setting (e.g. distance from land, qualifications and experience of crew). Consensus was quickly reached on key first-aid items but experts' views on emergency medicines differed. The study highlights the diversity of medical problems encountered on recreational dive boats. We offer preliminary guidance on the content of suitable first-aid kits and suggest areas for further research. Copyright © 2010 Elsevier Ltd. All rights reserved.

  15. M-COPA suppresses endolysosomal Kit-Akt oncogenic signalling through inhibiting the secretory pathway in neoplastic mast cells.

    Yasushi Hara

    Full Text Available Gain-of-function mutations in Kit receptor tyrosine kinase result in the development of a variety of cancers, such as mast cell tumours, gastrointestinal stromal tumours (GISTs, acute myeloid leukemia, and melanomas. The drug imatinib, a selective inhibitor of Kit, is used for treatment of mutant Kit-positive cancers. However, mutations in the Kit kinase domain, which are frequently found in neoplastic mast cells, confer an imatinib resistance, and cancers expressing the mutants can proliferate in the presence of imatinib. Recently, we showed that in neoplastic mast cells that endogenously express an imatinib-resistant Kit mutant, Kit causes oncogenic activation of the phosphatidylinositol 3-kinase-Akt (PI3K-Akt pathway and the signal transducer and activator of transcription 5 (STAT5 but only on endolysosomes and on the endoplasmic reticulum (ER, respectively. Here, we show a strategy for inhibition of the Kit-PI3K-Akt pathway in neoplastic mast cells by M-COPA (2-methylcoprophilinamide, an inhibitor of this secretory pathway. In M-COPA-treated cells, Kit localization in the ER is significantly increased, whereas endolysosomal Kit disappears, indicating that M-COPA blocks the biosynthetic transport of Kit from the ER. The drug greatly inhibits oncogenic Akt activation without affecting the association of Kit with PI3K, indicating that ER-localized Kit-PI3K complex is unable to activate Akt. Importantly, M-COPA but not imatinib suppresses neoplastic mast cell proliferation through inhibiting anti-apoptotic Akt activation. Results of our M-COPA treatment assay show that Kit can activate Erk not only on the ER but also on other compartments. Furthermore, Tyr568/570, Tyr703, Tyr721, and Tyr936 in Kit are phosphorylated on the ER, indicating that these five tyrosine residues are all phosphorylated before mutant Kit reaches the plasma membrane (PM. Our study provides evidence that Kit is tyrosine-phosphorylated soon after synthesis on the ER but is

    2017-09-01

    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

Coated bead was prepared by immobilization of antigen HCV recombinant on polystyrene bead. To obtain a good quality of reagent some parameters were optimized i.e.: colim used for purification. To determine the validity of the kit, validation which include comparison study and determination of specificity and sensitivity have been performed. A good quality of tracer has been able to prepared with high yield (74%) and high P/N value (15). The quality of coated bead is also reasonably good (P/N 34.3), and gave a good density and dissociation index (0.335 and 0.99% respectively). Both tracer and coated bead were remain stable after 2 months storage at 4 o C. In comparison with Elisa kit, the specificity and sensitivity of the HCV IRMA kit is reasonably high, 88.6% and 92.3% respectively

    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.

  13. Increasing the flexibility of the LANCE cAMP detection kit.

    Science.gov (United States)

    Hunter, Morag Rose; Glass, Michelle

    2015-01-01

    The detection of cAMP signalling is a common endpoint in the study of G-protein coupled receptors. A number of commercially available kits enable easy detection of cAMP. These kits are based on competition for a cAMP binding site on an antibody or cAMP binding protein and as such have a limited dynamic range. Here, we describe the optimisation of the commercially-available LANCE cAMP detection kit (PerkinElmer) to enable detection in cell lysates. This kit has been designed for use with live cells, with detection reagents applied to cells without wash steps. The standard protocol therefore requires that all assay reagents are compatible with the antibody and the final fluorescent detection stage, limiting the range of assay media and test compounds that can be utilised. The entire experiment must be repeated if cAMP levels fall outside the limited dynamic range. Here we describe a modified protocol that enables the assay to be performed on cell lysates, thereby overcoming these limitations. In this modified protocol, cells are stimulated for a cAMP response in standard media/buffers, washed and then lysed. The cell lysate is then assayed using a modified protocol for the LANCE cAMP detection kit. Samples were tested for stability following a freeze-thaw cycle. The modified LANCE cAMP detection protocol gives a reproducible measurement of cAMP in cell lysate. Lysate samples remain stable when stored at -80°C. Separating the stimulation and detection phases of this cAMP assay allows a vast array of cell stimulation conditions to be tested. The lysate-modified protocol for the LANCE cAMP detection kit therefore increases the flexibility, versatility and convenience of the assay. As samples are insensitive to freeze-thaw, it enables retesting of samples under different dilution conditions to ensure that all samples remain within the dynamic range of the standard curve.

    Hands-on learning allows students to understand science concepts by directly observing and experiencing the topics they are studying. The Planetary Science Institute (PSI) has created instructional rock kits that have been introduced to elementary and middle school teachers in Tucson, in our professional development workshops. PSI provides teachers with supporting material and training so that they can use the kits as tools for students’ hands-on learning. Use of these kits provides an important experience with natural materials that is essential to instruction in Earth and Space Science. With a stronger knowledge of science content and of how science is actually conducted, the workshops and kits have instilled greater confidence in teachers’ ability to teach science content. The Next Generation Science Standards (NGSS) Performance Expectations includes: “What makes up our solar system?” NGSS emphasizes the Crosscutting Concepts—Patterns Scale, Portion, and Quantity; and Systems and System Models. NGSS also states that the Nature of Science (NOS) should be an “essential part” of science education. NOS topics include understanding that scientific investigations use a variety of methods, that scientific knowledge is based on empirical evidence, that scientific explanations are open to revision in light of new evidence, and an understanding of the nature of scientific models.Addressing a need expressed by teachers for borrowing kits less expensive than our $2000 option, we created a Meteorite Mini-Kit. Each Mini-Kit contains eight rocks: an iron-bearing chondrite, a sliced chondrite (showing iron and chondrules), a tektite, a common Tucson rock, a river-polished rock, pumice, a small iron, and a rounded obsidian rock (false tektite). Also included in the Mini-Kits are magnets and a magnifier. The kits cost $40 to $50, depending on the sizes of the chondrites. A teacher can check out a classroom set of these which contains either 10 or 20 Mini-Kits. Each

    Individuals differ in their motives and strategies to cooperate in social dilemmas. These differences are reflected by an individual's social value orientation: proselfs are strategic and motivated to maximize self-interest, while prosocials are more trusting and value fairness. We hypothesize that when deciding whether or not to cooperate with a random member of a defined group, proselfs, more than prosocials, adapt their decisions based on past experiences: they 'learn' instrumentally to form a base-line expectation of reciprocity. We conducted an fMRI experiment where participants (19 proselfs and 19 prosocials) played 120 sequential prisoner's dilemmas against randomly selected, anonymous and returning partners who cooperated 60% of the time. Results indicate that cooperation levels increased over time, but that the rate of learning was steeper for proselfs than for prosocials. At the neural level, caudate and precuneus activation were more pronounced for proselfs relative to prosocials, indicating a stronger reliance on instrumental learning and self-referencing to update their trust in the cooperative strategy. © The Author (2017).

    Obesity, insulin resistance, and related pathologies are associated with immune-mediated chronic inflammation. Kit mutant mice are protected from diet-induced obesity and associated co-morbidities, and this phenotype has previously been attributed to their lack of mast cells. We performed a comprehensive metabolic analysis of Kit-dependent Kit(W/Wv) and Kit-independent Cpa3(Cre/+) mast-cell-deficient mouse strains, employing diet-induced or genetic (Lep(Ob/Ob) background) models of obesity. Our results show that mast cell deficiency, in the absence of Kit mutations, plays no role in the regulation of weight gain or insulin resistance. Moreover, we provide evidence that the metabolic phenotype observed in Kit mutant mice, while independent of mast cells, is immune regulated. Our data underscore the value of definitive mast cell deficiency models to conclusively test the involvement of this enigmatic cell in immune-mediated pathologies and identify Kit as a key hematopoietic factor in the pathogenesis of metabolic syndrome.

    A RIA-Mat T 3 kit was used for an in vitro measurement of triiodothyronine in serum. A resin strip was utilized to absorb free triiodothyronine after the serum was incubated with antibody against triiodothyronine. This test was easy to manipulate and the reproducibility test with same sera, dilution test, and recovery test were also satisfactory. The normal range of triiodothyronine determined with this test kit was 119 +- 40 ng/dl using 50 test sera. Ninety sera with various thyroid diseases were also determined. (auth.)

    The 2MASS Catalog Server Kit is open source software for use in easily constructing a high performance search server for important astronomical catalogs. This software utilizes the open source RDBMS PostgreSQL, therefore, any users can setup the database on their local computers by following step-by-step installation guide. The kit provides highly optimized stored functions for positional searchs similar to SDSS SkyServer. Together with these, the powerful SQL environment of PostgreSQL will meet various user's demands. We released 2MASS Catalog Server Kit version 2.1 in 2012 May, which supports the latest WISE All-Sky catalog (563,921,584 rows) and 9 major all-sky catalogs. Local databases are often indispensable for observatories with unstable or narrow-band networks or severe use, such as retrieving large numbers of records within a small period of time. This software is the best for such purposes, and increasing supported catalogs and improvements of version 2.1 can cover a wider range of applications including advanced calibration system, scientific studies using complicated SQL queries, etc. Official page: http://www.ir.isas.jaxa.jp/~cyamauch/2masskit/

  11. Overestimation of the 25(OH)D serum concentration with the automated IDS EIA kit.

    Science.gov (United States)

    Cavalier, Etienne; Huberty, Véronique; Cormier, Catherine; Souberbielle, Jean-Claude

    2011-02-01

    We have recently observed an increasing number of patients presenting very high serum levels of 25-hydroxyvitamin D [25(OH)D] (> 150 ng/mL), which, in all cases, had been measured with the IDS EIA kit adapted on different "open" automated platforms. We performed a comparison between the IDS EIA kit adapted on two different "open"automated platforms and the DiaSorin RIA. We found a systematic bias (higher levels with the IDS EIA kit) for concentrations more than 50-60 ng/mL that was less obvious when the IDS EIA was used in its manual procedure. We thus suggest to use the IDS EIA kit in its manual procedure rather than to adapt it on an automated platform, and to interpret cautiously a 25(OH)D greater than 100 ng/mL with this kit.

    After its launch on 2 December 1995, SOHO travelled to take up a special orbit 1.5 million kilometres away on the sunward side of the Earth, where the Sun never sets. The full scientific programme began in April 1996. The occasion for the briefing is the celebration of that second anniversary and of the mission's extension to 2003. Organized by the European Space Agency, the briefing will be hosted by the Rutherford Appleton Laboratory, which is near Oxford. Leading scientists associated with SOHO will announce to the press some remarkable new discoveries about the Sun's interior, atmosphere and solar wind. They will also briefly review the main achievements of the past two years. The role of SOHO as the chief watchdog for storms on the Sun that may affect the Earth will be demonstrated. Europe's creation of the finest spacecraft ever built to observe the Sun will be recalled by a top engineer from ESA. A speaker from NASA will explain transatlantic contributions to SOHO, which is a project of international cooperation between ESA and NASA. ESA's director of science will also be present, to relate SOHO to ESA's general science programme. A lunch-time talk by the BNSC's director of science completes the line-up of speakers. This is also an exceptional opportunity for the press to meet and interview scientists from all over Europe and the USA, who are attending a meeting at the Rutherford Appleton Laboratory of SOHO's Science Working Team (SWT). Journalists are usually excluded from such meetings. The Rutherford Appleton Laboratory plays a prominent part in SOHO, particularly through its provision of the CDS ultraviolet spectrometer. A visit to the CDS group will provide a chance to see what space research is really like. Please indicate your intention to attend, on the accreditation form that follows the schedule.

    1979-12-22

    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 6..mu..g/l to greater than 2 000 ..mu..g/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.

    2012-05-01

    Gene therapy has been regarded as an innovative potential treatment against serious congenital diseases. However, applications of gene therapy remain limited, partly because its clinical success depends on therapeutic gene-transduced cells acquiring a proliferative advantage. To address this problem, we have developed the antigen-mediated genetically modified cell amplification (AMEGA) system, which uses chimeric receptors to enable the selective proliferation of gene-transduced cells. In this report, we describe mimicry of c-Kit signaling and its application to the AMEGA system. We created an antibody/c-Kit chimera in which the extracellular domain of c-Kit is replaced with an anti-fluorescein single-chain Fv antibody fragment and the extracellular D2 domain of the erythropoietin receptor. A genetically modified mouse pro-B cell line carrying this chimera showed selective expansion in the presence of fluorescein-conjugated BSA (BSA-FL) as a growth inducer. By further engineering the transmembrane domain of the chimera to reduce interchain interaction we attained stricter ligand-dependency. Since c-Kit is an important molecule in the expansion of hematopoietic stem cells (HSCs), this antibody/c-Kit chimera could be a promising tool for gene therapy targeting HSCs.

    McComas, David C.

    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

    Full Text Available Burkholderia pseudomallei, the etiologic agent of melioidosis, is endemic in northern Australia and Southeast Asia and can cause severe septicemia that may lead to death in 20% to 50% of cases. Rapid detection of B. pseudomallei infection is crucial for timely treatment of septic patients. This study evaluated seven commercially available DNA extraction kits to determine the relative recovery of B. pseudomallei DNA from spiked EDTA-containing human whole blood. The evaluation included three manual kits: the QIAamp DNA Mini kit, the QIAamp DNA Blood Mini kit, and the High Pure PCR Template Preparation kit; and four automated systems: the MagNAPure LC using the DNA Isolation Kit I, the MagNAPure Compact using the Nucleic Acid Isolation Kit I, and the QIAcube using the QIAamp DNA Mini kit and the QIAamp DNA Blood Mini kit. Detection of B. pseudomallei DNA extracted by each kit was performed using the B. pseudomallei specific type III secretion real-time PCR (TTS1 assay. Crossing threshold (C T values were used to compare the limit of detection and reproducibility of each kit. This study also compared the DNA concentrations and DNA purity yielded for each kit. The following kits consistently yielded DNA that produced a detectable signal from blood spiked with 5.5×10(4 colony forming units per mL: the High Pure PCR Template Preparation, QIAamp DNA Mini, MagNA Pure Compact, and the QIAcube running the QIAamp DNA Mini and QIAamp DNA Blood Mini kits. The High Pure PCR Template Preparation kit yielded the lowest limit of detection with spiked blood, but when this kit was used with blood from patients with confirmed cases of melioidosis, the bacteria was not reliably detected indicating blood may not be an optimal specimen.

  20. Molecular Characterization of PDGFR-α/PDGF-A and c-KIT/SCF in Gliosarcomas

    2005-01-01

    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

    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 (c-kit + population (9.0%-0.1%). Because congenic Thy1.1 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.

    The aim of this study was to examine the effects of a stable surface (bench) vs. an unstable surface (Swiss ball) on muscle activation when performing the dumbbell chest press and shoulder press. Sixteen healthy men (24.19 +/- 2.17 years) performed 1 repetition maximum (1RM) tests for the chest press and shoulder press on a stable surface. A minimum of 48 hours post 1RM, subjects returned to perform 3 consecutive repetitions each of the chest press and shoulder press at 80% 1RM under 4 different randomized conditions (chest press on bench, chest press on Swiss ball, shoulder press on bench, shoulder press on Swiss ball). Electromyography was used to assess muscle activation of the anterior deltoid, pectoralis major, and rectus abdominus. The results revealed no significant difference in muscle activation between surface types for either exercise. This suggests that using an unstable surface neither improves nor impairs muscle activation under the current conditions. Coaches and other practitioners can expect similar muscle activation when using a Swiss ball vs. a bench.

    The preparation of the lyophilizing reagent, D-glucose-l-phosphate (GP) kit and the method of using this kit to label 99 Tc m to form 99 Tc m -GP for lung ventilation imaging at room temperature in a simple, rapid procedure are described. The stability of the lyophilizing reagent kit under various stock conditions is examined. The results show that all of the 99 Tc m -GP yields by the lyophilizing reagent kit are above 95% at 4 degree C (cold), 20-25 degree C (room temperature) and 40 degree C (oven) for 180, 90 and 3 days, respectively. The clinical practice indicates that in comparison with 99 Tc m -DTPA, 99 Tc m -GP has remarkable difference (P 99 Tc m -GP is an ideal radioaerosol for SPECT studies of lung ventilation. It has high alveolar deposition rate but low adhesion in the major airways compared to those of 99 Tc m -DTPA. 99 Tc m -GP also features prolonged pulmonary clearance time

    Increasingly, commercial immunoassay kits are used to support drug discovery and development. Longitudinally consistent kit performance is crucial, but the degree to which kits and reagents are characterized by manufacturers is not standardized, nor are the approaches by users to adapt them and evaluate their performance through validation prior to use. These factors can negatively impact data quality. This paper offers a systematic approach to assessment, method adaptation and validation of commercial immunoassay kits for quantification of biomarkers in drug development, expanding upon previous publications and guidance. These recommendations aim to standardize and harmonize user practices, contributing to reliable biomarker data from commercial immunoassays, thus, enabling properly informed decisions during drug development.

    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

    Objective: To develop a RIA kit for measurement of C-type natriuretic peptide (CNP) and to investigate its in clinical use. Methods: Conjugated CNP-TG was used to immunize the rabbit and the antibody against CNP was prepared. CNP RIA kits were made from it. Plasma CNP concentrations of 83 controls, 54 patients with coronary heart disease, 25 patients with heart failure and 73 patients with primary hypertension were determined with this RIA kit. Results: The sensitivity of detection was 5 pg/ml. The specificity of CNP anti-serum was high and did not react with ANP, NT, NPY, ET, CGRP and CT. The intra and interassy CVs were <10% and <15% respectively. The plasma levels of patients with coronary heart disease, heart failure and primary hypertension were 62.5 pg/ml, 47.9 pg/ml, 56.4 pg/ml respectively. There were all significantly higher than the level in controls (27.5 pg/ml). Conclusion: RIA of CNP with this kit is a simple, rapid method. It is a reliable means for studying the role of CNP in various physiological and pathophysiological states

    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

    The Washington State Cholinesterase Monitoring Program for pesticide handlers requires blood draws at local clinics, with samples tested at a central laboratory. At present, workers with inhibited cholinesterase activity may be re-exposed before they can be removed from work. In this study we explored the option of on-site testing at local clinics using the EQM Test-mate Kittrade mark, a portable cholinesterase test kit. Test kit cholinesterase activity measurements were performed on 50 blood samples by our research staff, and compared to measurements on the same samples by the Washington State Public Health Laboratory. Another set of samples was also analyzed with the test kit by medical staff at an eastern Washington clinic. Triplicate measurements with the test kit had a 3.3% average coefficient of variation (CV) for plasma cholinesterase (PChE), and a 3.5% average CV for erythrocyte cholinesterase (AChE) measurements. The kit's PChE measurements were similar to PHL measurements (average ratio of 0.98) when performed in the laboratory, but had a tendency to underestimate activity when used in the clinic setting (average ratio of 0.87). The kit systematically overestimated AChE activity by 42-48% relative to the PHL measurements, regardless of where the samples were analyzed. This easy-to-use test kit appeared to be a viable method for clinic-based PChE measurements, but was less consistent for AChE measurements performed in the clinic. Absolute measurements with the kit need to be evaluated carefully relative to standardized methods. (c) 2008 Wiley-Liss, Inc.

    Canine tumors are valuable comparative oncology models. This research was designed to create a sustainable biobank of canine mammary tumors for breast cancer research. The aim was to provide a well-characterized sample cohort for specimen sharing, data mining, and long-term research aims. Canine mammary tumors are most frequently managed at a local veterinary clinic or hospital. We adopted a biobank framework based on a large number of participating veterinary hospitals and clinics acting as collection centers that were serviced by a centralized storage facility. Recruitment was targeted at rural veterinary clinics. A tailored, stable collection kit (DogMATIC) was designed that was used by veterinarians in remote or rural locations to collect both fresh and fixed tissue for submission to the biobank. To validate this methodology the kit design, collection rate, and sample quality were analyzed. The Australian Veterinary Cancer Biobank was established as a network of 47 veterinary clinics and three veterinary pathology laboratories spanning over 200,000 km(2). In the first 12 months, 30 canine mammary tumor cases were submitted via the DogMATIC kit. Pure intact RNA was isolated in over 80% of samples with an average yield of 14.49 μg. A large network biobank, utilizing off-site collection with the DogMATIC kit, was successfully coordinated. The creation of the Australian Veterinary Cancer Biobank has established a long-term, sustainable, comparative oncology research resource in Australia. There are broader implications for biobanking with this very different form of collection and banking.

    2016-07-01

    Numerous commercial enzyme-linked immunosorbent assay (ELISA) kits exist to quantitatively detect bovine milk residues in foods. Milk contains many proteins that can serve as ELISA targets including caseins (α-, β-, or κ-casein) and whey proteins (α-lactalbumin or β-lactoglobulin). Nine commercially-available milk ELISA kits were selected to compare the specificity and sensitivity with 5 purified milk proteins and 3 milk-derived ingredients. All of the milk kits were capable of quantifying nonfat dry milk (NFDM), but did not necessarily detect all individual protein fractions. While milk-derived ingredients were detected by the kits, their quantitation may be inaccurate due to the use of different calibrators, reference materials, and antibodies in kit development. The establishment of a standard reference material for the calibration of milk ELISA kits is increasingly important. The appropriate selection and understanding of milk ELISA kits for food analysis is critical to accurate quantification of milk residues and informed risk management decisions. © 2016 Institute of Food Technologists®

    2015-03-01

    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.

  18. Milk intake in kits: not only the total amount matters

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available The aim of this work was to identify milk intake variation patterns in kits throughout lactation, to evaluate their permanent maternal component and their relationships with the performance of kits before and after weaning. To achieve this goal, we used 73 rabbit does, controlled between the 1st and the 4th lactation, which kindled 229 litters with a total of 2225 kits. The daily milk intake records per young rabbit were analysed using a principal component analysis (PCA. We found that 72.3% of the variability was explained by the first 3 principal components (PCs. PC1 explained 46.4% of the total variability, was associated with the total amount of milk intake during lactation and presented a repeatability of 0.27 (P0.05. This component was little related to performance traits. Therefore, it seems that milk plays 2 different roles at the beginning of feed intake; the most important would affect development of the kits and thus is related with high intake. The second one, for a given total amount of milk intake during lactation, would create a kind of competition between milk and feed intake at the end of lactation. The effects of both components still persist during the growing period and seem to be moderately affected by the mother.

    2014-07-01

    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.

    We report here on the imaging findings of the case of KIT-negative gastrointestinal stromal tumor (GIST) in the stomach of a 12-year-old girl. Radiologic studies revealed the presence of a huge exophytic growing mass that originated from the gastric wall and this mass consisted of solid and cystic components on USG, CT and MR. The cystic regions were mainly located at the periphery of the mass and they were revealed to be myxoid degeneration and hemorrhage on histopathologic examination. The tumor consisted of epithelioid and typical spindle cells and they showed negative immunoreactivity for KIT. Although KIT-negative GISTs are rare, they can be considered in the differential diagnosis when a large heterogeneous extraluminal mass that contains solid portions and various degrees of peripheral cystic regions is observed

    data import from external online sources and repositories has the big advantage that publication data are acquired and validated only once and can be used subsequently for manifold purposes such as websites, CVs, publication lists and reference management software. Due to the complexity of workflows, internal and external sources and the organisational infrastructure that is required for such an implementation, KIT has chosen a commercial software solution (by AVEDAS AG as the basic installation, and in cooperation with AVEDAS will expand it and adjust it to a tailor-made system that covers the entire KIT publication and research life cycle. The CRIS at KIT is part of a larger integrated and service-oriented approach to information management (Karlsruhe Integrated Information Management — KIM.

    We have studied the development of the C-peptide radioimmunoassay kit which is usable in the pancreatic function test with satisfactory results. The C-peptide antiserum was prepared by immunizing rabbits with synthetic human connecting peptide. The antiserum revealed no cross reaction with any C-peptides other than human C-peptide, porcine insulin and gastrointestinal hormone, and showed high specificity to human C-peptide. We adopted the double antibody method in B,F separation, and chose 4 0 C, 48 hrs. for 1st. incubation and 4 0 C, 24 hrs. for 2nd. incubation. On this kit, the assay range was 0.5 ng/ml-30 ng/ml, the recovery rate was 98.4%-107.8% in the recovery test, the coefficient of variance was 6.2% in the intra assay and was 7.6% in the inter assay. We think this kit is sufficiently usable to assay C-peptide in blood. (auth.)

    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.)

    Kaposis sarcoma (KS) is in angio proliferative disorder associated with human herpes virus 8 infection. Classic Ks is the most prevalent type of KS in countries of the Mediterranean basin including Egypt. Several in vitro studies have detected C-kit expression in AIDS related-KS however, only a few studies addressed this Issue In the classic type with no data on the ethnicity of studied cases. The prospect of installing targeted anti-c-kit treatment to KS patients presents a promising avenue in KS therapeutics. Aim: To elucidate the expression of c-kit in classic KS cases and study possible relations with expression of HHV8 latency-associated nuclear antigen-1 (LANA-1) and other clinico pathological parameters. Methods: Twenty four cases of classic KS of the plaque and nodular stages in the lower limb were studied. Immunohistochemical detection of HHV8-LANA-1 and c-kit was carried out on archival paraffin embedded tissue, possession of the pathology and dermatology Departments, Alexandria School Of Medicine, Egypt. Statistical analysis of possible reltions between both antigen and clinico pathological parameters (patient age and gender and histological stage) was performed. Results: HHV8 expression was detected in 100% of cases while c-kit immunoreactivity was found in 54.2% of cases. There was no correlation between c-kit and HHV8 immunoreactivity or any of the studied clinico pathological parameters. Conclusions: This is the first report of c-kit expression in classic KS in an ethnically homogeneous cohort of arabs of the Mediterranean region. We detected c-kit expression in about half the cases with no relationship to HHV8 LANA expression or clinico pathological parameters

    2014-02-01

    This short report evaluates the feasibility of using electronic vending machines for dispensing oral, fluid, rapid HIV self-testing kits in Los Angeles County. Feasibility criteria that needed to be addressed were defined as: (1) ability to find a manufacturer who would allow dispensing of HIV testing kits and could fit them to the dimensions of a vending machine, (2) ability to identify and address potential initial obstacles, trade-offs in choosing a machine location, and (3) ability to gain community approval for implementing this approach in a community setting. To address these issues, we contracted a vending machine company who could supply a customized, Internet-enabled machine that could dispense HIV kits and partnered with a local health center available to host the machine onsite and provide counseling to participants, if needed. Vending machines appear to be feasible technologies that can be used to distribute HIV testing kits.

    2015-08-04

    Why cooperation is well developed in human society is an unsolved question in biological and human sciences. Vast studies in game theory have revealed that in non-cooperative games selfish behavior generally dominates over cooperation and cooperation can be evolved only under very limited conditions. These studies ask the origin of cooperation; whether cooperation can evolve in a group of selfish individuals. In this paper, instead of asking the origin of cooperation, we consider the enhancement of cooperation in a small already cooperative society. We ask whether cooperative behavior is further promoted in a small cooperative society in which social penalty is devised. We analyze hawk-dove game and prisoner's dilemma introducing social penalty. We then expand it for non-cooperative games in general. The results indicate that cooperation is universally favored if penalty is further imposed. We discuss the current result in terms of the moral, laws, rules and regulations in a society, e.g., criminology and traffic violation.

  15. Role of ELA region in auto-activation of mutant KIT receptor: a molecular dynamics simulation insight.

    KIT receptor is the prime target in gastrointestinal stromal tumor (GISTs) therapy. Second generation inhibitor, Sunitinib, binds to an inactivated conformation of KIT receptor and stabilizes it in order to prevent tumor formation. Here, we investigated the dynamic behavior of wild type and mutant D816H KIT receptor, and emphasized the extended A-loop (EAL) region (805-850) by conducting molecular dynamics simulation (∼100 ns). We analyzed different properties such as root mean square cutoff or deviation, root mean square fluctuation, radius of gyration, solvent-accessible surface area, hydrogen bonding network analysis, and essential dynamics. Apart from this, clustering and cross-correlation matrix approach was used to explore the conformational space of the wild type and mutant EAL region of KIT receptor. Molecular dynamics analysis indicated that mutation (D816H) was able to alter intramolecular hydrogen bonding pattern and affected the structural flexibility of EAL region. Moreover, flexible secondary elements, specially, coil and turns were dominated in EAL region of mutant KIT receptor during simulation. This phenomenon increased the movement of EAL region which in turn helped in shifting the equilibrium towards the active kinase conformation. Our atomic investigation of mutant KIT receptor which emphasized on EAL region provided a better insight into the understanding of Sunitinib resistance mechanism of KIT receptor and would help to discover new therapeutics for KIT-based resistant tumor cells in GIST therapy.

    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.

    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.

    9 9 m Tc labelled 2-methoxy-isobutyl-isonitrile(MIBI) has been known as an imaging agent for myocardial perfusion. This radiopharmaceutical preparation gives the same satisfactory result as Thallium- 2 10TI, and presumably could replace 2 01TI because of same advantages. MIBI kit was formulated from MIBI ligand produced by RPC-BATAN which has been characterized and tested for quality. The formula used in this research referred to the formula of imported product(Cardiolite, MIBI kit produced by Dupont), and the quality control testing was performed by comparing some parameters to the imported product. The parameters used for QC testing were radiochemical purity, biodistribution in nice and heart imaging in human volunteer using gamma camera. The result of the experiment showed that the radiochemical purity was 95 % in average, biodistribution in heart to liver gave the ratio of 0.67, 1.5, and 2.53 respectively at 10, 30 and 60 minutes after injection. The result of clinical testing in some volunteers gave contrast images as good as given by Cardiolite. The optimum condition of freeze drying has been found, and the kit can be used for more than 6 months

    Full Text Available Purpose: The main purpose of this study was to compare the phenomenon of interfrm cooperation strategy in both hyper-growth, and stable-growth knowledge and technology–intensive frms, in a country characterized by a high level of generalized trust: Sweden. Methodology: Qualitative methods were incorporated: direct semistructured interviews with top managers in 13 ICT frms (8 hyper-growth and 5 stable-growth, analyzis of reports, corporate websites and press releases. Furthermore, interviews in 3 expert frms in the industry were conducted, facilitating interfrm cooperation. Conclusions: There were signifcant differences in interfrm cooperation strategy in two distinguished groups of the frms: hyper-growth, and stable-growth. Managers’ individual approaches to uncertainty, strategy and cooperation might be more important than institutional settings. The ICT frms operate in a constantly changing global environment and local context seems to have only a minor impact on the rules of the game in the industry. Research limitations: This study was a qualitative explorative approach as an introduction to further empirical research. Originality: The study presents an interfrm cooperation phenomenon incorporating different perspectives and settings. It contributes to alliance portfolio literature (forming and managing of alliance portfolio in a different context/country/industry, and enhances understanding of frm strategies characterized by different growth rates.

    Long-term reconstituting hematopoietic stem cells first arise from the aorta of the aorta-gonad-mesonephros (AGM) region in a mouse embryo. We have previously reported that in cultures of the dispersed AGM region, CD45{sup low}c-Kit{sup +} cells possess the ability to reconstitute multilineage hematopoietic cells, but investigations are needed to show that this is not a cultured artifact and to clarify when and how this population is present. Based on the expression profile of CD45 and c-Kit in freshly dissociated AGM cells from embryonic day 9.5 (E9.5) to E12.5 and aorta cells in the AGM from E13.5 to E15.5, we defined six cell populations (CD45{sup -}c-Kit{sup -}, CD45{sup -}c-Kit{sup low}, CD45{sup -}c-Kit{sup high}, CD45{sup low}c-Kit{sup high}, CD45{sup high}c-Kit{sup high}, and CD45{sup high}c-Kit{sup very} {sup low}). Among these six populations, CD45{sup low}c-Kit{sup high} cells were most able to form hematopoietic cell colonies, but their ability decreased after E11.5 and was undetectable at E13.5 and later. The CD45{sup low}c-Kit{sup high} cells showed multipotency in vitro. We demonstrated further enrichment of hematopoietic activity in the Hoechst dye-effluxing side population among the CD45{sup low}c-Kit{sup high} cells. Here, we determined that CD45{sup low}c-Kit{sup high} cells arise from the lateral plate mesoderm using embryonic stem cell-derived differentiation system. In conclusion, CD45{sup low}c-Kit{sup high} cells are the major hematopoietic cells of mouse AGM.

  6. 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.

    The mi locus of mice encodes a novel member of the basic-helix-loop-helix-leucine zipper protein family of transcription factors (hereafter called mi factor). In addition to microphthalmus, osteopetrosis, and lack of melanocytes, mice of mi/mi genotype are deficient in mast cells. Since the c-kit receptor tyrosine kinase plays an important role in the development of mast cells, and since the c-kit expression by cultured mast cells from mi/mi mice is deficient in both mRNA and protein levels, the mast cell deficiency of mi/mi mice has been attributed at least in part to the deficient expression of c-kit. However, it remained to be examined whether the c-kit expression was also deficient in tissues of mi/mi mice. In the present study, we examined the c-kit expression by mi/mi skin mast cells using in situ hybridization and immunohistochemistry. Moreover, we examined the c-kit expression by various cells other than mast cells in tissues of mi/mi mice. We found that the c-kit expression was deficient in mast cells but not in erythroid precursors, testicular germ cells, and neurons of mi/mi mice. This suggested that the regulation of the c-kit transcription by the mi factor was dependent on cell types. Mice of mi/mi genotype appeared to be a useful model to analyze the function of transcription factors in the whole-animal level.

    Full Text Available Introduction: Unstable surface training is often used to activate core musculature during resistance training. Unfortunately, unstable surface training is risky and leads to detraining. Purpose: The purpose of this study was to determine core muscle activation during stable surface ground-based lifts. Methods: Fourteen recreational trained and former NCAA DI athletes (weight 84.2 ± 13.3 kg; height 176.0 ± 9.5 cm; age 20.9 ± 2.0 years volunteered for participation. Subjects completed two ground-based lifts: overhead press and push-press. Surface EMG was recorded from 4 muscles on the right side of the body (Rectus Abdominus (RA, External Oblique (EO, Transverse Abdominus (TA, and Erector Spinae (ES. Results: Paired sample T-tests identified significant muscle activation differences between the overhead press and the push-press included ES and EO. Average and peak EMG for ES was significantly greater in push-press (P<0.01. Anterior displacement of COP was significantly greater in push-press compared to overhead press during the eccentric phase. Conclusion: The push-press was identified as superior in core muscle activation when compared to the overhead pressing exercise. Keywords: torso, stability, weight lifting, resistance training

    Plasma vasoactive intestinal peptide (VIP) concentrations of normal individuals and patients with pancreatitis were studied using a VIP RIA kit. The inter-assay and intra-assay variation of this kit were between 2.1 and 9.4 %. The VIP levels increased in the acute phase of acute pancreatitis and patients with chronic pancreatitis. The VIP concentration increased during the first 30 min of glucose tolerance test, but this increase was much smaller than that in insulin. These results suggest that this kit is useful for physiologic and pathologic changes in the VIP level. (author)

After labelling each vial is sufficient for three to four patient doses. However, it becomes very expensive when only a single patient dose is required (up to $350 per dose). Our goal in this study was to subdivide the MIBI kit into fractions to establish the stability of these split kits. If successful, this would reduce the expense and make the product more cost-effective. After dissolving the Iyophilised ingredients of a MIBI vial with 5 mL of N2-purged normal saline, 1 mL aliquots of the resultant solution were dispensed into N2-filled vials under aseptic conditions. The vials were then stored frozen at -70 deg C. 99mTc-MIBI was prepared by the addition of 2 GBq of {sup 99m}Tc-pertechnetate in I mL of normal saline to the fractionated kit, followed by heating at 100 deg C for 10 minutes at 0, 2, 4 and 8 weeks post-fractionation. The product was allowed to cool before testing for radiochemical purity (RCP) for up to six hours post-labelling. The RCP of each vial was determined using aluminium oxide coated aluminium TLC strips (Merck) run in 100% ethanol. Over the eight-week evaluation period RCP was maintained at 94.2 + 1.3% over six hours (n = 16), which is greater than the minimum recommended RCP (90%) for patient use. These results show that fractionation of MIBI cold kits and sub-frozen storage under an N{sub 2} atmosphere provides a stable and economical multidose product. Using this method the cost of a single patient dose can be reduced considerably from $350, even allowing for the labour involved in the fractionation

    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.

    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.

    Full Text Available During embryogenesis, the mammalian heart develops from a primitive heart tube originating from two bilateral primary heart fields located in the lateral plate mesoderm. Cells belongings to the pre-cardiac mesoderm will differentiate into early cardiac progenitors, which express early transcription factors which are also common to the Isl-1 positive cardiac progenitor cells isolated from the developing pharyngeal mesoderm and the foetal and post-natal mice hearts. A second population of cardiac progenitor cells positive to c-Kit has been abundantly isolated from adult hearts. Until now, these two populations have been considered two different sets of progenitor cells present in the heart in different stages of an individual life. In the present study we collected embryonic, foetal and infant hearts, and we tested the hypotheses that c-Kit positive cells, usually isolated from the adult heart, are also present in the intra-uterine life and persist in the adult heart after birth, and that foetal Isl-1 positive cells are also positive to c-Kit. Using immunohistochemistry we studied the temporal distribution of Isl-1 positive and c-Kit/CD105 double positive cells, and by immunofluorescence and confocal analysis we studied the co-localization of c-Kit and Isl-1 positive cells. The results indicated that cardiomyocytes and interstitial cells were positive for c-Kit from the 9th to the 19th gestational week, that cells positive for both c-Kit and CD105 appeared in the interstitium at the 17th gestational week and persisted in the postnatal age, and that the Isl-1 positive cells were a subset of the c-Kit positive population.

    The tyrosine kinase receptor c-Kit is critically involved in the modulation of nociceptive sensitivity in mice. Ablation of the c-Kit gene results in hyposensitivity to thermal pain, whereas activation of c-Kit produces hypersensitivity to noxious heat, without altering sensitivity to innocuous mechanical stimuli. In this study, we investigated the role of c-Kit signaling in human pain perception. We hypothesized that subjects treated with Imatinib or Nilotinib, potent inhibitors of tyrosine kinases including c-Kit but also Abl1, PDFGFRα, and PDFGFRβ, that are used to treat chronic myeloid leukemia (CML), would experience changes in thermal pain sensitivity. We examined 31 asymptomatic CML patients (14 male and 17 female) receiving Imatinib/Nilotinib treatment and compared them to 39 age- and sex-matched healthy controls (12 male and 27 female). We used cutaneous heat and cold stimulation to test normal and noxious thermal sensitivity, and a grating orientation task to assess tactile acuity. Thermal pain thresholds were significantly increased in the Imatinib/Nilotinib-treated group, whereas innocuous thermal and tactile thresholds were unchanged compared to those in the control group. In conclusion, our findings suggest that the biological effects of c-Kit inhibition are comparable in mice and humans in that c-Kit activity is required to regulate thermal pain sensitivity but does not affect innocuous thermal and mechanical sensation. The effect on experimental heat pain observed in our study is comparable to those of several common analgesics; thus modulation of the c-Kit pathway can be used to specifically modulate noxious heat and cold sensitivity in humans.

    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.

    Full Text Available This paper proposes a user cooperation stimulating strategy among rational users. The strategy is based on cooperative game theory and enacted in the context of cooperative relay networks. Using the pricing-based mechanism, the system is modeled initially with two nodes and a Base Station (BS. Within this framework, each node is treated as a rational decision maker. To this end, each node can decide whether to cooperate and how to cooperate. Cooperative game theory assists in providing an optimal system utility and provides fairness among users. Under different cooperative forwarding modes, certain questions are carefully investigated, including “what is each node's best reaction to maximize its utility?” and “what is the optimal reimbursement to encourage cooperation?” Simulation results show that the nodes benefit from the proposed cooperation stimulating strategy in terms of utility and thus justify the fairness between each user.

    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.)

    An optimized biomanufacturing process in mammalian cells is contingent on the ability of the producing cells to reach high viable cell densities. In addition, at the peak of growth, cells need to continue producing the biological entity at a consistent quality. Thus, engineering cells with robust growth performance and resilience to variable stress conditions is highly desirable. The tyrosine kinase receptor, KIT, plays a key role in cell differentiation and the survival of several immune cell types. Its oncogenic mutant, D816V, endows cells with high proliferation capacity, and resistance to kinase inhibitors. Importantly, this onco-KIT mutant when introduced into various cell types is arrested in the endoplasmic reticulum in a constitutively active form. Here, we investigated the effect of oncogenic D816V KIT on the performance of CHO-K1 cells under conventional tissue culture growth settings and when adapted, to shaking conditions. The onco-KIT promoted global protein synthesis, elevated the expression of a secretable transgene, enhanced proliferation, and improved the overall titers of a model glycoprotein. Moreover, the expression of the onco-KIT endowed the cells with a remarkable resistance to various stress conditions. Our data suggest that the introduction of onco-KIT can serve as a strategy for improving glycoprotein biomanufacturing. Biotechnol.

    Two different HEDP content kits (Kit A, HEDP: 1 mg, SnCl 2 x 2H 2 O: 0.5 mg; and Kit B, HEDP: 10 mg, SnCl 2 x 2H 2 O: 0.5 mg) were evaluated for their stability against dillution. Sup(99m)Tc-HEDP solutions prepared from these two kits were diluted from 10 to 6000 fold with 0.9% NaCl solution just before evaluation both in vivo and in vitro. In the case of Kit A, significant soft tissue uptake in vivo and released free pertechnetate in vitro were observed by diluting the sup(99m)Tc-HEDP solution. On the other hand, sup(99m)Tc-HEDP prepared from Kit B was found to be sufficiently stable against dilution. The stability after preparation of each diluted sup(99m)-HEDP was also greatly affected by its HEDP concentration. Preliminary analysis of absorption spectra for each 99 Tc-HEDP indicated the possibility of two different sup(99m)Tc-HEDP complex formation by varied HEDP concentration. These results indicated that a cold reagent like Kit A might cause a higher soft tissue uptake due to its dilution in vivo during a clinical study for bone scanning. (orig.) [de

    In this paper, we report on the development of a 3D vision field upgrade kit for TALON robot consisting of a replacement flat panel stereoscopic display, and multiple stereo camera systems. An assessment of the system's use for robotic driving, manipulation, and surveillance operations was conducted. The 3D vision system was integrated onto a TALON IV Robot and Operator Control Unit (OCU) such that stock components could be electrically disconnected and removed, and upgrade components coupled directly to the mounting and electrical connections. A replacement display, replacement mast camera with zoom, auto-focus, and variable convergence, and a replacement gripper camera with fixed focus and zoom comprise the upgrade kit. The stereo mast camera allows for improved driving and situational awareness as well as scene survey. The stereo gripper camera allows for improved manipulation in typical TALON missions.

    To determine the return rate of community-delivered fecal immunochemical test (FIT) kits in a rural population and to identify significant predictors of returning kits. Residents were recruited in 8 rural Kentucky counties to enroll in the study and receive an FIT kit. Of 345 recruited, 82.0% returned an FIT kit from the point of distribution. These participants were compared to the remainder relative to age, sex, marital status, having an annual income below $15,000, not graduating from high school, not having a regular health care provider, not having health care coverage, being a current smoker, indicating current overweight or obese status, and a scale measure of fatalism pertaining to colorectal cancer. Predictors achieving significance at the bivariate level were entered into a stepwise logistic regression model to calculate adjusted OR and 95% CI. The return rate was 82.0%. In adjusted analyses, those indicating an annual income of less than $15,000 were 2.85 times more likely to return their kits (95% CI: 1.56-5.24; P < .001). Also, those not perceiving themselves to be overweight/obese were 1.95 times more likely to return their kits (95% CI: 1.07-3.55; P = .029). An outreach-based colorectal cancer screening program in a rural population may yield high return rates. People with annual incomes below $15,000 and those not having perceptions of being overweight/obese may be particularly likely to return FIT kits. © 2016 National Rural Health Association.

    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.

    Chronic prostatitis (CP) with complex pathogenesis is difficult for treatment. c-kit has been associated with the control of cell proliferation of prostate cells. This study aims to evaluate the role of resveratrol, an activator of Sirt1, in regulating the expression of c-kit in CP and investigate the consequent effects on cell cycle. Rat model of CP was established through subcutaneous injections of diphtheria-pertussis-tetanus vaccine and subsequently treated with resveratrol. Hematoxylin and eosin staining was performed to identify the histopathological changes in prostates. Western blotting and immunohistochemical staining examined the expression level of c-kit, stem cell factor (SCF), Sirt1, and cell cycle-associated proteins. The model group exhibited severe diffuse chronic inflammation, characterized by leukocyte infiltration and papillary frond protrusion into the gland cavities, and a notable increase in prostatic epithelial height. Gland lumen diameter was also significantly smaller; the activity of c-kit/SCF in the CP rats was increased significantly compared to the control group. Meanwhile, the cell cycle proteins are dysregulated significantly in CP rats. Resveratrol treatment significantly improved these factors by Sirt1 activation. Dysregulation of cell cycle was involved in the pathological processes of CP, which was improved after resveratrol treatment by the downregulation of c-kit/SCF by activating Sirt1.

    Full Text Available This article is based on a new archival find from the papers of foreign correspondent Louis P. Lochner. It proves the existence of a secret German-American cooperation between Associated Press (AP and the ›Bureau Laux‹, an agency of the SS and the German Foreign Office, during the war years 1942–1945. With the permission of the Roosevelt administration, AP and the Bureau Laux exchanged photos via diplomatic pouch on a daily basis until spring 1945, first via Lisbon and from 1944 via Stockholm as well. Approximately 40,000 photos were swapped in this way between the war enemies while the battles of the Second World War were fought and the Holocaust was taking place. In Berlin, the AP photos were presented daily to the highest Nazi leadership. They were then also used for anti-American and anti-Semitic propaganda in the German press. Conversely, thousands of Nazi photos received by AP New York via Lisbon and Stockholm were printed in the American and international press. This article sheds new light on both AP as a news and picture agency and on foreign reporting during the Nazi era and the Second World War. * * * Der im vorliegenden Aufsatz präsentierte Quellenfund aus dem Nachlass des Auslandskorrespondenten Louis P.

    The chips exhausted from various machine tools are massy, occupy much space and make working environment worse by staying added cutting oil to lower part. The chips are exhausted as a result of machining and have not constant quality. Even if used material is same the chips have various shapes and properties by kinds and machining methods of used machine tools, and are troublesome materials from a standpoint of their treatment. Pressing and solidification of the chips have frequently been tried. A chip compacting press introduced in this paper, a relatively cheap chip compacting press aimed for relatively small scale chip treatment, and has such characteristics and effects as follows. Chips are pressed and solidified by each raw material, so fractional management can be easily conducted. As casting metal chips and curled chips of iron and aluminum can be pressed to about 1/3 to 1/5 and about 1/40, respectively, space saving can be conducted. Chip compacting pressing upgrades its transporting efficiency to make possible to reduce its transporting cost. As chip solidification controls its oxidation and most cutting oil are removed, chips are easy to recycle. 2 figs., 1 tab.

    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

    Ribosomal RNA (rRNA) comprises at least 90% of total RNA extracted from mammalian tissue or cell line samples. Informative transcriptional profiling using massively parallel sequencing technologies requires either enrichment of mature poly-adenylated transcripts or targeted depletion of the rRNA fraction. The latter method is of particular interest because it is compatible with degraded samples such as those extracted from FFPE and also captures transcripts that are not poly-adenylated such as some non-coding RNAs. Here we provide a cross-site study that evaluates the performance of ribosomal RNA removal kits from Illumina, Takara/Clontech, Kapa Biosystems, Lexogen, New England Biolabs and Qiagen on intact and degraded RNA samples. We find that all of the kits are capable of performing significant ribosomal depletion, though there are differences in their ease of use. All kits were able to remove ribosomal RNA to below 20% with intact RNA and identify ~ 14,000 protein coding genes from the Universal Human Reference RNA sample at >1FPKM. Analysis of differentially detected genes between kits suggests that transcript length may be a key factor in library production efficiency. These results provide a roadmap for labs on the strengths of each of these methods and how best to utilize them.

    The efficiency of utilization of milk amino acids for body gain in suckling mink kits from small (n = 3), medium (n = 6) and large litters (n = 9) was investigated by using 36 mink dams and their litters for measurements during lactation weeks 1 through 4. Measurements on each dam and litter were...... performed once, hence three dams per litter size each week (n = 9). Individual milk intake of kits was determined, milk samples were collected and kits were killed for determination of amino acid composition. The most abundant amino acids in milk were glutamate, leucine and aspartate making up about 40......% of total amino acids. Branched chained amino acids made up slightly more than 20% and sulphur containing amino acids less than 5% of total milk amino acids. In kit bodies the sum of glutamate, aspartate and leucine made up about 32% of amino acids, branched chain amino acids about 16% and sulphur...

    The freeze-dried Mag 3 kits were designed for both ligand trans chelation and direct labelling techniques. The solution of Sn-Mag 3 was sterilized by 0.22 μU mill pore filtration and dispensed in a laminar flow hood (1 m I / vial) then, the vials were introduced to the lyophilized. The process of lyophilization was continued for 24 hours. At end of the cycle, the vials were closed under nitrogen. The moisture content of the freeze-dried Mag 3 kits was determined and it was found equal to 0.1% also, the losses of tin (II) during the freeze-drying cycle did not exceed 5%. It was found that the Mag 3 freeze-dried kits were sterile, pyrogen free and does not have any unexpected toxicity. The prepared Mag 3 freeze-dried kits have high radiochemical purity > 97% and high stability for more than 8 h after labelling. The biodistribution shows rapid renal excretion at 15 min post injection. 3 figs., 4 tabs

    As there is no specific treatment for dengue, early detection and access to proper treatment may lower dengue fatality. Therefore, having new techniques for the early detection of dengue fever, such as the use of dengue test kit, is vitally important. The aims of the study were: 1) identify factors associated with acceptance of a home self-test kit for dengue fever if the dengue test is available to the public and 2) find out the characteristics of the test kits that influence the use of the dengue test kit. A national telephone survey was carried out with 2,512 individuals of the Malaysian public aged 18-60 years old. Individuals were contacted by random digit dialling covering the whole of Malaysia from February 2012 to June 2013. From 2,512 participants, 6.1 % reported to have heard of the availability of the dengue home test kit and of these, 44.8 % expressed their intention to use the test kit if it was available. Multivariate logistic regressions indicated that participants with primary (OR: 0.65; 95 % CI: 0.43-0.89; p = 0.02, vs. tertiary educational level) and secondary educational levels (OR: 0.73; 95 % CI: 0.57-0.90; p = 0.01, vs. tertiary educational level) were less likely than participants with a tertiary educational level to use a home self-testing dengue kit for dengue if the kit was available. Participants with lower perceived barriers to dengue prevention (level of barriers 0-5) were less likely (OR: 0.67, 95 % CI: 0.53-0.85, p dengue kit for dengue if the kit was available compared to those with higher perceived barriers to dengue prevention (level of barriers 6-10). Participants with a lower total dengue fever knowledge score (range 0-22) were also less likely to use a home self-testing dengue kit for dengue if the kit was available (OR: 0.75; 95 % CI: 0.61-0.91, p = 0.001, vs. higher total dengue fever knowledge score) compared to those with a higher total dengue fever knowledge score (range 23-44).

    In this study, advantages and disadvantages of the innovative, low-oxygen spiral-filter press system were studied in comparison with the belt press, commonly applied in small and medium size enterprises for the production of cloudy apple juice. On the basis of equivalent throughput, a higher juice yield could be achieved with spiral-filter press. Also a more turbid juice with a higher content of suspended solids could be produced. The avoidance of enzymatic browning during juice extraction led to an attractive yellowish juice with an elevated phenolic content. Moreover, it was found that juice produced with spiral-filter press demonstrates a higher retention of phenolic compounds during the downstream processing steps and storage. The results demonstrates the advantage of the use of a spiral-filter press in comparison with belt press in the production of a high quality cloudy apple juice rich in phenolic compounds, without the use of oxidation inhibiting additives.

    Salmonella, one of the most common causes of foodborne illness, is a significant public health concern worldwide. There is a need in the food industry for methods that are simple, rapid, and sensitive for the detection of foodborne pathogens. In this study, the Samsung Salmonella Detection Kit, a real-time PCR assay for the detection of Salmonella, was evaluated according to the current AOAC guidelines. The validation consisted of lot-to-lot consistency, stability, robustness, and inclusivity/exclusivity studies, as well as a method comparison of 10 different food matrixes. In the validation, the Samsung Salmonella Detection Kit was used in conjunction with the Applied Biosystems StepOnePlus PCR system and the Samsung Food Testing Software for the detection of Salmonella species. The performance of the assays was compared to the U.S. Department of Agriculture/Food Safety and Inspection Service-Microbiology Laboratory Guidebook (USDA/FSIS-MLG) 4.05: Isolation and Identification of Salmonella from Meat, Poultry, Pasteurized Egg, and Catfish and the and U.S. Food and Drug Administration/Bacteriological Analytical Manual (FDA/BAM) Chapter 5 Salmonella reference methods. The validation was conducted using an unpaired study design for detection of Salmonella spp. in raw ground beef, raw pork, raw ground pork, raw chicken wings, raw salmon, alfalfa sprouts, pasteurized orange juice, peanut butter, pasteurized whole milk, and shell eggs. The Samsung Salmonella Detection Kit demonstrated lot-to-lot consistency among three independent lots as well as ruggedness with minor modifications to changes in enrichment incubation time, enrichment incubation temperature, and DNA sample volume for PCR reaction. Stability was observed for 13 months at -20 degrees C and 3 months at 5 degrees C. For the inclusivity/exclusivity study, the Samsung Salmonella Detection Kit correctly identified 147 Salmonella species isolates out of 147 isolates tested from each of three different enrichment

    2018-01-01

    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.

  20. 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.

    The EQM Research, Inc., portable test kit was evaluated as a surveillance tool for blood cholinesterase levels among migrant workers and their children. Laboratory validation demonstrated a linear relationship between the reference Ellman and kit methods (Ellman = 0.95 x kit result + 0.82, r2 = 0.98). Pre- and post-season cholinesterase levels measured in 70 farm workers were within normal ranges, but significantly different at 28.5 and 29.7 U/g Hb, respectively (paired t-test, p = 0.014). Results from 98 migrant farm worker children and a comparison group of 53 age-matched non-agricultural children showed that cholinesterase levels were not significantly different between the agricultural and non-agricultural children (ANOVA, p = 0.69). These data demonstrate that a portable test kit can provide useful data pesticide exposures when measurements are made in a temperature-controlled setting.

  3. The structural insights of stem cell factor receptor (c-Kit interaction with tyrosine phosphatase-2 (Shp-2: An in silico analysis

    2010-01-01

    Full Text Available Abstract Background Stem cell factor (SCF receptor c-Kit is recognized as a key signaling molecule, which transduces signals for the proliferation, differentiation and survival of stem cells. Binding of SCF to its receptor triggers transactivation, leading to the recruitment of kinases and phosphatases to the docking platforms of c-Kit catalytic domain. Tyrosine phosphatase-1 (Shp-1 deactivates/attenuates 'Kit' kinase activity. Whereas, Asp816Val mutation in the Kit activation loop transforms kinase domain to a constitutively activated state (switch off-to-on state, in a ligand-independent manner. This phenomenon completely abrogates negative regulation of Shp-1. To predict the possible molecular basis of interaction between c-Kit and Shp-1, we have performed an in silico protein-protein docking study between crystal structure of activated c-Kit (phosphorylated c-Kit and full length crystal structure of Shp-2, a close structural counterpart of Shp-1. Findings Study revealed a stretch of conserved amino acids (Lys818 to Ser821 in the Kit activation domain, which makes decisive H-bonds with N-sh2 and phosphotyrosine binding pocket residues of the phosphatase. These H-bonds may impose an inhibitory steric hindrance to the catalytic domain of c-Kit, there by blocking further interaction of the activation loop molecules with incoming kinases. We have also predicted a phosphotyrosine binding pocket in SH2 domains of Shp-1, which is found to be predominantly closer to a catalytic groove like structure in c-Kit kinase domain. Conclusions This study predicts that crucial hydrogen bonding between N-sh2 domain of Shp-1 and Kit activation loop can modulate the negative regulation of c-Kit kinase by Shp-1. Thus, this finding is expected to play a significant role in designing suitable gain-of-function c-Kit mutants for inducing conditional proliferation of hematopoietic stem cells.

    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.

    During cell division/mitosis, a specific subset of proteins is spatially and temporally assembled into protein super complexes in three distinct regions, i.e. centrosome/spindle pole, kinetochore/centromere and midbody/cleavage furrow/phragmoplast/bud neck, and modulates cell division process faithfully. Although many experimental efforts have been carried out to investigate the characteristics of these proteins, no integrated database was available. Here, we present the MiCroKit database (http://microkit.biocuckoo.org) of proteins that localize in midbody, centrosome and/or kinetochore. We collected into the MiCroKit database experimentally verified microkit proteins from the scientific literature that have unambiguous supportive evidence for subcellular localization under fluorescent microscope. The current version of MiCroKit 3.0 provides detailed information for 1489 microkit proteins from seven model organisms, including Saccharomyces cerevisiae, Schizasaccharomyces pombe, Caenorhabditis elegans, Drosophila melanogaster, Xenopus laevis, Mus musculus and Homo sapiens. Moreover, the orthologous information was provided for these microkit proteins, and could be a useful resource for further experimental identification. The online service of MiCroKit database was implemented in PHP + MySQL + JavaScript, while the local packages were developed in JAVA 1.5 (J2SE 5.0).

    Accurate identification of mastitis-causing bacteria supports effective management and can be used to implement selective use of antimicrobials for treatment. The objectives of this study were to compare the results from a culture-based mastitis pathogen detection test kit ('VetoRapid', Vétoquinol) with standard laboratory culture and to evaluate the potential suitability of the test kit to inform a selective treatment programme. Overall 231 quarter milk samples from five UK dairy farms were collected. The sensitivity and specificity of the test kit for the identification of Escherichia coli, Staphylococcus aureus, coagulase-negative staphylococci, Streptococcus uberis and Enterococcus spp. ranged from 17 per cent to 84 per cent and 92 per cent to 98 per cent, respectively. In total, 23 of 68 clinical samples were assigned as meeting the requirement for antimicrobial treatment (Gram-positive organism cultured) according to standard culture results, with the test kit results having sensitivity and specificity of 91 per cent and 78 per cent, respectively. Several occurrences of misidentification are reported, including S. aureus being misidentified as coagulase-negative staphylococci and vice versa. The test kit provides rapid preliminary identification of five common causes of bovine mastitis under UK field conditions and is likely to be suitable for informing selective treatment of clinical mastitis caused by Gram-positive organisms.

  10. 'Co-operation and Communism cannot work side by side': Organized Consumers and the Early Cold War in Britain.

    Science.gov (United States)

    Gurney, Peter

    2018-04-02

    This article contributes to a better understanding of labour anti-communism in Britain through an exploration of the evolution of ideas and attitudes within the co-operative movement during the early Cold War. It demonstrates that the period witnessed an increasingly rigid separation of co-operation from communism and argues that this separation made it harder for activists within the co-operative movement to imagine a total or utopian alternative to capitalism. Drawing particularly on a close reading of the co-operative press as well as other sources, the study is divided into three main parts. The first section discusses sympathy among co-operators for the achievements of the Soviet Union, which increased during the war against fascism. The article then moves on to consider the continuing dialogue between British co-operators and their counterparts in European communist states and how international tensions shaped co-operators' views. The final major section explores the hardening of attitude towards communism after Marshall Aid was declared in June 1947, and underlines the role played by figures such as A. V. Alexander and Jack Bailey who worked with the Information Research Department at the Foreign Office to spread anti-communism within the movement. The conclusion reflects, more speculatively, on what implications this shift may have had for the medium and long-term decline of co-operation and the hegemony of capitalist consumerism post-war.

    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.

    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.

    Structure and diversity of microbial communities are an important research topic in biology, since microbes play essential roles in the ecology of various environments. Different DNA isolation protocols can lead to data bias and can affect results of next-generation sequencing. To evaluate the impact of protocols for DNA isolation from soil samples and also the influence of individual handling of samples, we compared results obtained by two researchers (R and T) using two different DNA extraction kits: (1) MO BIO PowerSoil ® DNA Isolation kit (MO_R and MO_T) and (2) NucleoSpin ® Soil kit (MN_R and MN_T). Samples were collected from six different sites on Okinawa Island, Japan. For all sites, differences in the results of microbial composition analyses (bacteria, archaea, fungi, and other eukaryotes), obtained by the two researchers using the two kits, were analyzed. For both researchers, the MN kit gave significantly higher yields of genomic DNA at all sites compared to the MO kit (ANOVA; P  technicians for thorough microbial analyses and to obtain accurate estimates of microbial diversity.

    To develop heart failure (HF) and chronic obstructive pulmonary disease (COPD) self-management kits in an accountable care organization (ACO) to facilitate patients' self-care and prevent hospital readmissions. Pharmacists practice in an outpatient-based ACO. They participate in interprofessional office visits with providers and independently manage maintenance pharmacotherapies. Pharmacists collaborate with an interprofessional team within the ACO including physicians, nurses, case managers, and paramedics. Two commonly encountered diseases are chronic COPD and HF. Reducing preventable readmissions for these conditions are important quality benchmarks and cost-saving strategies. Pharmacists were responsible for developing HF and COPD self-management kits containing patient education materials and prescriptions to facilitate self-care. Prior to kit development, pharmacists performed a literature review to determine the presence of previously published findings on these topics. The interprofessional team continually evaluates the successes and limitations of this initiative. Pharmacists developed training and instructions for ACO allied health professionals in an effort to incorporate the self-management kits in clinical practice. The initial literature search revealed no studies describing the intervention of interest. Innovative programs designed to help reduce preventable readmissions are lacking in primary care. Implementation of the self-management kits was accepted by interprofessional ACO leadership and is currently being integrated into allied health workflow. Patients at risk for having an exacerbation of COPD or HF should receive self-management strategies. Prompt therapy prior to exacerbations reduces hospital admissions and readmissions, speeds recovery, and slows disease progression. Pharmacist-facilitated implementation of self-management kits may be developed by interprofessional health care teams.

    Sox2 and Pax6 are transcription factors that direct cell fate decision during neurogenesis, yet the mechanism behind how they cooperate on enhancer DNA elements and regulate gene expression is unclear. By systematically interrogating Sox2 and Pax6 interaction on minimal enhancer elements, we found that cooperative DNA recognition relies on combinatorial nucleotide switches and precisely spaced, but cryptic composite DNA motifs. Surprisingly, all tested Sox and Pax paralogs have the capacity to cooperate on such enhancer elements. NMR and molecular modeling reveal very few direct protein-protein interactions between Sox2 and Pax6, suggesting that cooperative binding is mediated by allosteric interactions propagating through DNA structure. Furthermore, we detected and validated several novel sites in the human genome targeted cooperatively by Sox2 and Pax6. Collectively, we demonstrate that Sox-Pax partnerships have the potential to substantially alter DNA target specificities and likely enable the pleiotropic and context-specific action of these cell-lineage specifiers. © The Author(s) 2015.

    The ubiquicidin 29-41 fragment (UBI) is a cationic antimicrobial peptide. An instant kit formulation was developed for the preparation of 99m Tc-UBI 29-41 in high radiochemical yield and its use as an infection imaging agent in humans was evaluated. The components were selected to produce a direct 99m Tc labeling, presumably to the amine groups of Lys and Arg7. 99m Tc-UBI 29-41 obtained from the lyophilized kit showed radiochemical purity of >97% with an average target/non-target ratio of 2.3±0.6 in positive infection sites at 2 hours. Kits were stable at 4 deg C for over 6 months. (author)

    2015-10-01

    c-KIT and DOG-1 are 2 highly expressed proteins in gastrointestinal stromal tumors. Few studies had investigated c-KIT, but not DOG-1, expression in colorectal carcinoma (CRC). This study aims to investigate expressions of c-KIT and DOG-1 in colorectal mucinous carcinoma and nonmucinous carcinoma using manual tissue microarray technique. In this work, we studied tumor tissue specimens from 150 patients with colorectal mucinous (MA) and nonmucinous adenocarcinoma (NMA). High-density manual tissue microarrays were constructed using modified mechanical pencil tip technique, and immunohistochemistry for c-KIT and DOG-1 was done. We found that aberrant c-KIT expression was detected in 12 cases (8%); 6 cases (4%) showed strong expression. Aberrant DOG-1 expression was detected in 15 cases (10%); among them, only 4 cases (2.7%) showed strong expression. Nonmucinous adenocarcinoma showed a significantly high expression of c-KIT, but not DOG-1, than MA. Aberrant c-KIT and DOG-1 expressions were significantly unrelated but were associated with excessive microscopic abscess formation. Neither c-KIT nor DOG-1 expression showed a significant impact on disease-free survival or overall survival. In conclusion, aberrant c-KIT and DOG-1 expressions in CRC are rare events, either in NMA or MA. Nonmucinous adenocarcinoma showed a significantly higher expression of c-KIT, but not DOG-1, than MA. The expressions of both in CRC are significantly unrelated but are associated with microscopic abscess formation. Neither c-KIT nor DOG-1 expression showed a significant impact on disease-free survival or overall survival. So, c-KIT and DOG-1 immunostaining is not a cost-effective method of identifying patients with CRC who may benefit from treatment with tyrosine kinase inhibitors. Copyright © 2015 Elsevier Inc.

  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

    Sodium hydrous titanium oxide is an ion exchange resin which can be used for immobilizing medium level waste (MLW) liquors. When hot pressed, it undergoes conversion to a ceramic. Three low melting point materials (borax, bismuth trioxide, and a mixture of PbO/CuO) were added to the (Na)HTiO and the effect that each of these had on aiding densification was assessed. Hot pressing temperature, applied pressure, and percentage addition of hot pressing aid were varied. Percentage open porosity, flexural strength, and leachability were measured. There was a linear relationship between the percentage open porosity and the logarithm of the leach rate for a constant percentage addition of each additive

    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.

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

    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.

    In cases such as mass disasters or missing persons, human remains are challenging to identify as they may be fragmented, burnt, been buried, decomposed, and/or contain inhibitory substances. This study compares the performance of a relatively new STR kit in the US market (Investigator® 24plex QS kit; Qiagen) with the GlobalFiler® PCR Amplification kit (Thermo Fisher Scientific) when genotyping highly inhibited and low level DNA samples. In this study, DNA samples ranging from 1 ng to 7.8 pg were amplified to define the sensitivity of two systems. In addition, DNA (1 ng and 0.1 ng input amounts) was spiked with various concentrations of five inhibitors common to human remains (humic acid, melanin, hematin, collagen, calcium). Furthermore, bone (N = 5) and tissue samples from decomposed human remains (N = 6) were used as mock casework samples for comparative analysis with both STR kits. The data suggest that the GlobalFiler® kit may be slightly more sensitive than the Investigator® kit. On average STR profiles appeared to be more balanced and average peak heights were higher when using the GlobalFiler® kit. However, the data also show that the Investigator® kit may be more tolerant to common PCR inhibitors. While both STR kits showed a decrease in alleles as the inhibitor concentration increased, more complete profiles were obtained when the Investigator® kit was used. Of the 11 bone and decomposed tissue samples tested, 8 resulted in more complete and balanced STR profiles when amplified with the GlobalFiler® kit. Copyright © 2018 Elsevier B.V.

    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.

    Metrnl is a newly discovered secreted protein with neurotrophic activity and metabolic effect, while in earlier studies its circulating level in human was not explored. We evaluated two commercial enzyme-linked immunosorbent assay kits (DY7867-05, R&D Systems and SK00478-02, Aviscera Bioscience) for the detection of human circulating Metrnl. The DY7867-05 kit showed superiority over the SK00478-02 kit since it generated better curve fitting degree, smaller variation among tests, higher inter-assay reproducibility and better specificity, and could effectively detect human Metrnl in six types of blood samples. Subsequent analysis was performed using the DY7867-05 kit. Sample storage conditions were investigated. No gender difference in circulating Metrnl levels was found, while people with newly diagnosed type 2 diabetes mellitus (T2DM) had significantly lower Metrnl levels compared to the healthy controls.

    Full Text Available Background: KIT and mitogen-activated protein kinase cascade are important for melanomagenesis. In the present study, we analyzed the frequency of BRAF, NRAS, KIT, GNAQ and GNA11 gene mutations and investigated their association with clinicopathological features of melanomas in Turkish population. Materials and Methods: Forty-seven primary cutaneous melanomas were included in our study. Sanger sequencing method was used for mutation analysis in all cases. Results: Mean age was 62.1 (29-101 years. Female:male ratio was 17:30. Among 47 melanomas, 14 (29.8% BRAF, 10 (21.3% NRAS, 4 (8.5% KIT and 1(2.1% GNAQ gene mutations were detected. Two of the KIT mutations were found in acral lentiginous melanoma (ALM. In the head and neck region, mutation frequency was significantly lower than in other locations (P = 0.035. The only GNAQ gene mutation (p.Q209L was detected in a melanoma arising from blue nevus located on the scalp. None of the melanomas harbored NRAS exon 2, KIT exon 13/17/18, GNAQ exon 4 and GNA11 exon 4/5 mutations. Overall mutation frequency did not show significant difference between metastatic (8/14, 57.1% and nonmetastatic (18/33, 54.5% patients. We did not observe any significant association between mutation status and gender or age of various patients. Conclusions: Our results support that BRAF and NRAS gene mutations are common in cutaneous melanomas. The activating mutations of KIT gene are rare and especially seen in ALM. GNAQ and GNA11 mutations are infrequent in cutaneous melanomas and may be associated only with melanomas arising from blue nevus.

    Full Text Available Abstract Background As there is no specific treatment for dengue, early detection and access to proper treatment may lower dengue fatality. Therefore, having new techniques for the early detection of dengue fever, such as the use of dengue test kit, is vitally important. The aims of the study were: 1 identify factors associated with acceptance of a home self-test kit for dengue fever if the dengue test is available to the public and 2 find out the characteristics of the test kits that influence the use of the dengue test kit. Methods A national telephone survey was carried out with 2,512 individuals of the Malaysian public aged 18–60 years old. Individuals were contacted by random digit dialling covering the whole of Malaysia from February 2012 to June 2013. Results From 2,512 participants, 6.1 % reported to have heard of the availability of the dengue home test kit and of these, 44.8 % expressed their intention to use the test kit if it was available. Multivariate logistic regressions indicated that participants with primary (OR: 0.65; 95 % CI: 0.43–0.89; p = 0.02, vs. tertiary educational level and secondary educational levels (OR: 0.73; 95 % CI: 0.57–0.90; p = 0.01, vs. tertiary educational level were less likely than participants with a tertiary educational level to use a home self-testing dengue kit for dengue if the kit was available. Participants with lower perceived barriers to dengue prevention (level of barriers 0–5 were less likely (OR: 0.67, 95 % CI: 0.53–0.85, p < 0.001, vs. higher perceived barriers to use a home self-testing dengue kit for dengue if the kit was available compared to those with higher perceived barriers to dengue prevention (level of barriers 6-10. Participants with a lower total dengue fever knowledge score (range 0–22 were also less likely to use a home self-testing dengue kit for dengue if the kit was available (OR: 0.75; 95 % CI: 0.61–0.91, p = 0.001, vs. higher total dengue

    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.

    2009-01-01

    Traditionally coupled field nuclear reactor analysis has been carried out using several loosely coupled solvers, each having been developed independently from the others. In the field of multi-physics, the current generation of object-oriented tool kits provides robust close coupling of multiple fields on a single framework. This paper describes the initial results obtained as part of continuing research in the use of the OpenFOAM multi-physics tool kit for reactor dynamics application development. An unstructured, three-dimensional, time-dependent multi-group diffusion code Diffusion FOAM has been developed using the OpenFOAM multi-physics tool kit as a basis. The code is based on the finite-volume methodology and uses a newly developed block-coupled sparse matrix solver for the coupled solution of the multi-group diffusion equations. A description of this code is given with particular emphasis on the newly developed block-coupled solver, along with a selection of results obtained thus far. The code has performed well, indicating that the OpenFOAM tool kit is suited to reactor dynamics applications. This work has shown that the neutronics and simplified thermal-hydraulics of a reactor May be represented and solved for using a common calculation platform, and opens up the possibility for research into robust close-coupling of neutron diffusion and thermal-fluid calculations. This work has further opened up the possibility for research in a number of other areas, including research into three-dimensional unstructured meshes for reactor dynamics applications. (authors)

    Most newborn screening laboratories use CE-marked or FDA-approved test-kits, like in routine clinical chemistry. National regulations require only minimal evaluation from the customer, if the test-kits are used as specified by the manufacturer. The microtiter-based kit-concept is often based on the perception, that the laboratory always processes whole microtiter plates. However, in the daily routine, this is rather a rare exception, which leads to much higher costs per newborn, compared to t...

  8. c-Kit-mediated functional positioning of stem cells to their niches is essential for maintenance and regeneration of adult hematopoiesis.

    Directory of Open Access Journals (Sweden)

    Yuki Kimura

    Full Text Available The mechanism by which hematopoietic stem and progenitor cells (HSPCs through interaction with their niches maintain and reconstitute adult hematopoietic cells is unknown. To functionally and genetically track localization of HSPCs with their niches, we employed novel mutant loxPs, lox66 and lox71 and Cre-recombinase technology to conditionally delete c-Kit in adult mice, while simultaneously enabling GFP expression in the c-Kit-deficient cells. Conditional deletion of c-Kit resulted in hematopoietic failure and splenic atrophy both at steady state and after marrow ablation leading to the demise of the treated adult mice. Within the marrow, the c-Kit-expressing GFP(+ cells were positioned to Kit ligand (KL-expressing niche cells. This c-Kit-mediated cellular adhesion was essential for long-term maintenance and expansion of HSPCs. These results lay the foundation for delivering KL within specific niches to maintain and restore hematopoiesis.

    Early growth response 1 (Egr1) is a key transcription factor that mediates the action of estrogen (E 2 ) to establish uterine receptivity for embryo implantation. However, few direct target genes of EGR1 have been identified in the uterus. Here, we demonstrated that E 2 induced EGR1-regulated transcription of c-Kit, which plays a crucial role in cell fate decisions. Spatiotemporal expression of c-Kit followed that of EGR1 in uteri of ovariectomized mice at various time points after E 2 treatment. E 2 activated ERK1/2 and p38 to induce EGR1, which then activated c-Kit expression in the uterus. EGR1 transfection produced rapid and transient induction of c-KIT in a time- and dose-dependent manner. Furthermore, luciferase assays to measure c-Kit promoter activity confirmed that a functional EGR1 binding site(s) (EBS) was located within -1 kb of the c-Kit promoter. Site-directed mutagenesis and chromatin immunoprecipitation-PCR for three putative EBS within -1 kb demonstrated that the EBS at -818/-805 was critical for EGR1-dependent c-Kit transcription. c-Kit expression was significantly increased in the uterus on day 4 and administration of Masitinib, a c-Kit inhibitor, effectively interfered with embryo implantation. Collectively, our results showed that estrogen induces transcription factor EGR1 to regulate c-Kit transcription for uterine receptivity for embryo implantation in the mouse uterus.

    2014-10-01

    Full Text Available Adenoid cystic carcinoma (ACC is an aggressive malignant neoplasm of the salivary glands in which c-Kit is overexpressed and activated, although the mechanism for this is as yet unclear. We analyzed 27 sporadic ACC tumor specimens to examine the biologic and clinical significance of c-Kit activation. Mutational analysis revealed expression of wild-type c-Kit in all, eliminating gene mutation as a cause of activation. Because stem cell factor (SCF is c-Kit's sole ligand, we analyzed its expression in the tumor cells and their environment. Immunohistochemistry revealed its presence in c-Kit–positive tumor cells, suggesting an activation of autocrine signaling. We observed a significant induction of ERK1/2 in the cells. SCF staining was also found in other types of non-cancerous cells adjacent to tumors within salivary glands, including stromal fibroblasts, neutrophils, peripheral nerve, skeletal muscle, vascular endothelial cells, mucous acinar cells, and intercalated ducts. Quantitative PCR showed that the top quartile of c-Kit mRNA expression distinguished ACCs from normal salivary tissues and was cross-correlated with short-term poor prognosis. Expression levels of SCF and c-Kit were highly correlated in the cases with perineural invasion. These observations suggest that c-Kit is potentially activated by receptor dimerization upon stimulation by SCF in ACC, and that the highest quartile of c-Kit mRNA expression could be a predictor of poor prognosis. Our findings may support an avenue for c-Kit-targeted therapy to improve disease control in ACC patients harboring the top quartile of c-Kit mRNA expression.

    Bulk Al/4wt-%Al{sub 2}O{sub 3} nanocomposites were prepared by consolidating nanocomposite powders using pressureless microwave sintering, microwave-assisted hot press sintering and conventional hot pressing techniques. Microstructural observations revealed that the microwave-assisted hot press sintering at different sintering temperatures of 400.deg.C and 500.deg.C resulted in more densification and smaller grain size for Al/Al{sub 2}O{sub 3} nanocomposite as compared with the conventional hot pressing. Moreover, the application of pressure in microwave sintering process led to more densification and grain growth. Mechanical properties resulting from microhardness and nanoindentation tests were also compared between three-method processed samples. It was found that the microwave-assisted hot-pressed sample exhibited higher hardness and elastic modulus in comparison with microwave-sintered and conventional hot-pressed samples. The improvement in the mechanical properties can be ascribed to lower porosity of microwave-assisted hot-pressed sample.

    2010-01-01

    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.

    Blood pressure transducer kits are equipped with two types of Planecta™ ports-the flat-type Planecta™ port (FTP) and the Planecta™ port with a three-way stopcock (PTS). We reported that FTP application decreased the natural frequency of the kits. However, Planecta™ is an invaluable tool as it prevents infection, ensures technical simplicity, and excludes air. Hence, an ideal Planecta™ port that does not decrease the frequency characteristics is required. As a first step in this direction, we aimed to assess the influence of PTSs on the natural frequency of blood transducer kits. A DTXplus transducer kit (DT4812J; Argon Medical Devices, TX, USA) was used along with ≥1 PTSs (JMS, Hiroshima, Japan), and the frequency characteristics were assessed. The natural frequency and damping coefficient of each kit were obtained by using frequency characteristics analysis software, and these parameters were evaluated by plotting them on Gardner's chart. Regardless of whether one or two PTSs were inserted, the natural frequency of the kits only slightly decreased (from 42.5 to 41.1 Hz, when 2 PTSs were used). Thus, the frequency characteristics of the kits with PTSs were adequate for pressure monitoring. The insertion of ≥2 FTPs in pressure transducer kits should be avoided, as they markedly decrease the natural frequency and lead to underdamping. However, the effect of PTS insertion in pressure transducer kits on the frequency characteristics is minimal. Thus, we found that the use of PTS markedly improved the frequency characteristics as compared to the use of FTP.

    AIM: To investigate the c-kit expression in biliary tract cancer cell lines and histological sections from patients with extrahepatic cholangiocarcinoma (CC) and to evaluate the efficacy of in vitro and in vitro treatment with imatinib mesilate. METHODS: The protein expression of c-kit in the human biliary tract cancer cell lines Mz-ChA-2 and EGI-1 and histological sections from 19 patients with extrahepatic CC was assessed by immunoblotting, immunocytochemistry, and immunohistochemistry. The anti-proliferative effect of imatinib mesilate on biliary tract cancer cell lines Mz-ChA-2 and EGI-1 was studied in vitro by automated cell counting. In addition, immunodeficient NMRI mice (TaconicTM) were subcutaneously injected with 5 x 106 cells of cell lines MzChA-2 and EGI-1. After having reached a tumour volume of 200 mm3, daily treatment was started intraperitoneally with imatinib mesilate at a dose of 50 mg/kg or normal saline (NS). Tumor volume was calculated with a Vernier caliper. After 14 d, mice were sacrificed with tumors excised and tumor mass determined. RESULTS: Immunoblotting revealed presence of c-kit in Mz-ChA-2 and absence in EGI-1 cells. Immunocytochemistry with c-kit antibodies displayed a cytoplasmatic and membraneous localization of receptor protein in Mz-ChA-2 cells and absence of c-kit in EGI-1 cells. c-kit was expressed in 7 of 19 (37%) extrahepatic human CC tissue samples, 2 showed a moderate and 5 a rather weak immunostaining. Imatinib mesilate at a low concentration of 5 µmol/L caused a significant growth inhibition in the c-kit positive cell line Mz-ChA-2 (31%), but not in the c-kit negative cell line EGI-1 (0%) (P < 0.05). Imatinib mesilate at an intermediate concentration of 10 µmol/L inhibited cellular growth of both cell lines (51% vs 57%). Imatinib mesilate at a higher concentration of 20 µmol/L seemed to have a general toxic effect on both cell lines. The IC50 values were 9.7 µmol/L and 11 µmol/L, respectively. After 14 d of in vitro

    As for the influences of Chuetsu-Oki Earthquake on Kashiwazaki-Kariwa Nuclear Power Station, we can conclude that 'the safety function of the nuclear power station, that is, 'Shutdown', 'Cooling down' and 'Isolating' functioned as per designed even against an earthquake beyond assumption, and fundamental nuclear safety could assured'. Nevertheless, it is said that one of the causes that harmful rumor had spread was due to mass communication media. In the press reports on some nuclear power station when affected by an earthquake and on trouble in the nuclear power station in the future, we will propose that the publication should be really useful for habitants and citizens and be promoted in the positive and expected direction, in order not to make the same mistake as this time. JSME should aim at implement the above-mentioned proposal under cooperation with other academic societies and organizations. (author)

  1. US-India agreement for peaceful nuclear cooperation

    International Nuclear Information System (INIS)

    2008-01-01

    The United States and India acheived a historic agreement for strategic partnership after the completion of negotiations on the bilateral agreement for peaceful nuclear cooperation, also known as the agreement of 123. This agreement regulates the civilian nuclear trade between the two countries and opens the door wide to U.S. and Indian companies for a partnership in every other country in the civil nuclear industry. This agreement has opened the door to complete the remaining steps for the the widest American Indian cooperation in the field of civil uses of atomic energy. Critics to the agreement within the United States say that the agreement reflected serious consequences on the ability of the United States to force other countries to comply with the prevention of nuclear proliferation. The global criticism focused on that the agreement strikes at the heart of the Treaty on the Non-Proliferation of Nuclear Weapons, and is considered a dangerous precedent to break the laws of the International Tribunal, and especially the laws and rules of the International Group of Suppliers, which includes 45 countries. The International Atomic Energy Agency (IAEA) says that the agreement is an important step towards meeting India's growing energy needs, especially nuclear technology which is the engine of development. Immediately after the completion of the United States and India for their bilateral agreement for nuclear cooperation, Israel announced that it was seeking U.S. help in the establishment of a power reactor while pressing the direction of tightening control over Iran's nuclear program while some Arab countries announced their desire to have nuclear reactors for electricity generation purposes.

    The effects of pressing temperature and initial microstructure on the equal channel angular (ECA) pressing of Ti-6Al-4V alloy were investigated in this study. The ECA pressing was carried out isothermally with route C at 500 C, 600 C and 700 C for two typical microstructures, i.e., the Widmanstaetten microstructure and the equiaxed microstructure. The results showed that ECA pressing at 600 C and 700 C was successful without producing any noticeable segment at the specimen surfaces, while a large amount of surface segments were produced at 500 C. After 1 pass pressing at 600 C, the equiaxed microstructure showed more uniform material flow at the surface than the Widmanstaetten microstructure. However, this microstructural influence was diminished with increase of the number of the ECA pressing. A flow-localization parameter that quantifies the flow non-uniform tendency in case of flow softening materials was used to explain the different results in each microstructure. (orig.)

    The regulation mechanism of inflammation inducing prostate carcinogenesis remains largely unknown. Therefore, we investigated the role of the c-kit/SCF pathway, which has been associated with the control of prostate carcinogenesis, in chronic prostatitis (CP) rats and evaluated the anti-prostatitis effect of resveratrol. We performed hemolysin and eosin staining to evaluate the histopathological changes in prostates. Multiple approaches evaluated the expression levels of c-kit, stem cell factor (SCF), Sirt1, and carcinogenesis-associated proteins. The CP group exhibited severe diffuse chronic inflammation. Meanwhile, the prostate cells appeared atypia; the activity of c-kit/SCF was upregulated, and carcinogenesis-associated proteins are dysregulated significantly in CP rats. Resveratrol treatment significantly improved these factors by Sirt1 activation. In summary, CP could further cause prostate carcinogenesis, which may be associated with activated c-kit/SCF signaling. Resveratrol treatment could improve the progression of CP via the downregulation of c-kit/SCF by activating Sirt1.

    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. ©Martin Zens, Peter Woias, Norbert P Suedkamp, Philipp Niemeyer.

    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 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

    2009-01-01

    The 99m Tc-ciprofloxacin radiopharmaceutical is available in the lyophilized-kit which is separately packed in two vials, ciprofloxacin lactate and Sn-tartrate, respectively. Preparation of 99m Tc-ciprofloxacin was performed by adding 99m Tc radionuclide into ciprofloxacin lactate solution, followed by addition of Sn-tartrate solution. The complement information was needed by user in order to assure the successful preparation and utilization of this radiopharmaceutical. Meanwhile, this investigation was performed to obtained the several physicochemical and biological characters of 99m Tc-ciprofloxacin prepared from the radiopharmaceutical lyophilized-kit of ciprofloxacin lactate. The radiochemical purity was determined with instant thin layer chromatography (ITLC-SG) using acetone and solution of dichloromethane : methanol : ammonium hydroxide : acetonitrile : (4:4:2:1) as a mobile phases. The plasma binding protein of 99m Tc-ciprofloxacin was investigated in-vitro by precipitation method using 5% of trichloro acetic acid solution, whereas the lipophilicity (P) was obtained by determination of octanol-water partition. Beside that, studies on the effect of volume of Na 99m TcO4 solution to radiochemical purity of 99m Tc-ciprofloxacin has been carried out. From the experiment, it was obtained that 99m Tc-ciprofloxacin has 95.85 ± 2.10 % of radiochemical purity, the human plasma binding protein of 58.35 ± 2.05 % and the lipophilicity (P) = 0.024 ± 0.005. The volume more than 2 mL of Na 99m TcO4 solution on the labelling of ciprofloxacin gave less than 90 % of radiochemical purity. The labelling efficiency of 44.79 % was obtained after filtration of 99m Tc-ciprofloxacin. The stability test on 99m Tc-ciprofloxacin and ciprofloxacin lyophilized-kit were performed by determining their radiochemical purities. The 99m Tcciprofloxacin was still able to be used until 4 hours after labelling with radiochemical purity of 91.61 ± 1.60 %. The stability determination showed

    A field kit has been developed which greatly simplifies the performance of the 48-hour in vitro test for drug resistance in Plasmodium falciparum. The kit uses an easily reconstituted lyophilized culture medium, and requires only a fingerprick blood sample. In parallel tests with 13 isolates of P. falciparum in Haiti, the new technique had a success rate equal to that of the previously described method, with comparable results in terms of parasite susceptibility in vitro to chloroquine and pyrimethamine.

  20. AML1/ETO trans-activates c-KIT expression through the long range interaction between promoter and intronic enhancer.

    The AML1/ETO onco-fusion protein is crucial for the genesis of t(8;21) acute myeloid leukemia (AML) and is well documented as a transcriptional repressor through dominant-negative effect. However, little is known about the transactivation mechanism of AML1/ETO. Through large cohort of patient's expression level data analysis and a series of experimental validation, we report here that AML1/ETO transactivates c-KIT expression through directly binding to and mediating the long-range interaction between the promoter and intronic enhancer regions of c-KIT. Gene expression analyses verify that c-KIT expression is significantly high in t(8;21) AML. Further ChIP-seq analysis and motif scanning identify two regulatory regions located in the promoter and intronic enhancer region of c-KIT, respectively. Both regions are enriched by co-factors of AML1/ETO, such as AML1, CEBPe, c-Jun, and c-Fos. Further luciferase reporter assays show that AML1/ETO trans-activates c-KIT promoter activity through directly recognizing the AML1 motif and the co-existence of co-factors. The induction of c-KIT promoter activity is reinforced with the existence of intronic enhancer region. Furthermore, ChIP-3C-qPCR assays verify that AML1/ETO mediates the formation of DNA-looping between the c-KIT promoter and intronic enhancer region through the long-range interaction. Collectively, our data uncover a novel transcriptional activity mechanism of AML1/ETO and enrich our knowledge of the onco-fusion protein mediated transcription regulation. © 2017 Wiley Periodicals, Inc.

    C-kit receptor is a member of a family of growth factor receptors that have tyrosine kinase activity, and are involved in the transduction of growth regulatory signals across plasma membrane by activation of its ligand, kitl/scf. The present study analysed mRNA and protein expression profiles of c-kit in the gonads of catfish, Clarias gariepinus, using real time PCR, in situ hybridization and immunohistochemistry. Tissue distribution analysis revealed higher expression mainly in the catfish gonads. Ontogeny studies showed minimal expression during early developmental stages and highest during 50-75 days post hatch, and the dimorphic expression in gonads decreased gradually till adulthood, which might suggest an important role for this gene around later stages of sex differentiation and gonadal development. Expression of C-kit was analysed at various phases of gonadal cycle in both male and female, which showed minimal expression during the resting phase, and higher expression in male compared to females during the pre-spawning phase. In vitro and in vivo induction using human chorionic gonadotropin elevated the expression of c-kit indicating the regulatory influence of hypothalamo-hypophyseal axis. In vivo transient gene silencing using c-kit-esiRNA in adult catfish during gonadal recrudescence showed a decrease in c-kit expression, which affected the expression level of germ cell meiotic marker sycp3, as well as several factors and steroidogenic enzyme genes involved in germ cell development. Decrease in the levels of serum 11-KT and T were also observed after esiRNA silencing. The findings of this study suggest that c-kit has an important role in the process of germ cell proliferation, development and maturation during gonadal development and recrudescence in catfish.

    The readiness for spontaneous cooperation together with the assumptions that others share this cooperativity has been identified as a fundamental feature that distinguishes humans from other animals, including the great apes. At the same time, cooperativity presents an evolutionary puzzle because non-cooperators do better in a group of cooperators. We develop here an analysis of the process leading to cooperation in terms of rationality concepts, game theory and epistemic logic. We are, however, not attempting to reconstruct the actual evolutionary process. We rather want to provide the logical structure underlying cooperation in order to understand why cooperation is possible and what kind of reasoning and beliefs would lead to cooperative decision-making. Game theory depends on an underlying common belief in non-cooperative rationality of the players, and cooperativity similarly can utilize a common belief in cooperative rationality as its basis. We suggest a weaker concept of rational decision-making in games that encompasses both types of decision-making. We build this up in stages, starting from simple optimization, then using anticipation of the reaction of others, to finally arrive at reflexive and cooperative reasoning. While each stage is more difficult than the preceding, importantly, we also identify a reduction of complexity achieved by the consistent application of higher stage reasoning.

    Autosomal short tandem repeat (STR) analysis has become highly relevant in the identification of victims from mass disasters and terrorist attacks. In such events, gender misidentification can be of grave consequences, yet the list reporting amelogenin amplification failure using STR multiplex kits continues to grow. Presented here are three such examples. In the first case, we present two male suspects who demonstrated amelogenin Y-deficient results using two commercial kit procedures. The presence of their Y chromosomes was proven by obtaining a Y-haplotype. The second case demonstrated a profile from a third male suspect where only the Y homolog of the XY pair was amplified. In events such as mass disasters or terrorist attacks, timely and reliable high throughput DNA typing results are essential. As the number of reported cases of amplification failure at the amelogenin gene continues to grow, we suggest that the incorporation of a better gender identification tool in commercial kits is crucial.

    This article will discuss how to design computer applications that enhance the quality of work and products, and will relate the discussion to current themes in the field of Computer-Supported Cooperative Work (CSCW). Cooperation is a key element of computer use and work practice, yet here...... a specific "CSCW approach is not taken." Instead the focus is cooperation as an important aspect of work that should be integrated into most computer support efforts in order to develop successful computer support, however, other aspects such as power, conflict and control must also be considered....

    Full Text Available In the present study four commercially available DNA extraction kits (Wizard® Genomic DNA Purification Kit, High Pure PCR Template Kit, DNeasy mericon Food and GeneJET PCR Purification Kit, as well as standard phenol/chloroform isolation technique have been evaluated regarding their concentration, purity and suitability for amplification of porcine DNA in dry/fermented sausages. The isolates were assessed for quantity and quality using spectrophotometer (IMPLEN GmbH, Germany. To verify template usability and quality of isolated DNA, the polymerase chain reaction (PCR targeting at porcine cytochrome b by species specific primers was used. The comparison of extraction methods revealed satisfactory efficiency and purity of all extraction kits, while with standard phenol/chloroform isolation method high concentrations of DNA with low A260/280 were obtained. However, all the investigated techniques proved to be suitable for identification of porcine DNA in dry/fermented sausage. Thus, the standard phenol/chloroform DNA extraction method, as the cost-effective one, can be recommended as a good alternative to more expensive isolation kits when investigating the presence of pork DNA in dry/ fermented meat products.

    Accurate titer determination of recombinant proteins is crucial for evaluating protein production cell lines and processes. Even though enzyme-linked immunosorbent assay (ELISA) is the most widely used assay for determining protein titer, little is known about the accuracy of commercially available...... ELISA kits. We observed that estimations of recombinant human ø1-antitrypsin (rø1AT) titer by Coomassie-stained SDS-PAGE gels did not correspond to previously obtained titers obtained by a commercially available ELISA kit. This prompted us to develop two independent quantification assays based...... on biolayer interferometry and reversed-phase high-performance liquid chromatography. We compared the rø1AT titer obtained by these assays with three different off-the-shelf ELISA kits and found that the ELISA kits led to inconsistent results. The data presented here show that recombinant protein titers...

  9. YY1 regulates melanocyte development and function by cooperating with MITF.

    Directory of Open Access Journals (Sweden)

    Juying Li

    Full Text Available Studies of coat color mutants have greatly contributed to the discovery of genes that regulate melanocyte development and function. Here, we generated Yy1 conditional knockout mice in the melanocyte-lineage and observed profound melanocyte deficiency and premature gray hair, similar to the loss of melanocytes in human piebaldism and Waardenburg syndrome. Although YY1 is a ubiquitous transcription factor, YY1 interacts with M-MITF, the Waardenburg Syndrome IIA gene and a master transcriptional regulator of melanocytes. YY1 cooperates with M-MITF in regulating the expression of piebaldism gene KIT and multiple additional pigmentation genes. Moreover, ChIP-seq identified genome-wide YY1 targets in the melanocyte lineage. These studies mechanistically link genes implicated in human conditions of melanocyte deficiency and reveal how a ubiquitous factor (YY1 gains lineage-specific functions by co-regulating gene expression with a lineage-restricted factor (M-MITF-a general mechanism which may confer tissue-specific gene expression in multiple lineages.

    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.

    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.

  16. Effect of Radioactivity of Technetium-99m on the Autosterilization Process of non-sterile Tetrofosmin Kits

    Full Text Available Technetium-99m labeled radiopharmaceutical is commonly used in nuclear medicines as a diagnostic agent, by mixing the sterile kit with Tc-99m. Manufacturing of kits requires an aseptic facility which need to be well designed and maintained according to cGMP, since mostly kits can not be terminally sterilized. Radiopharmaceuticals as pharmaceuticals containing radionuclide is assumed to have an autosterilization property, but correlation between radioactivity and capability of killing microorganisms has to be studied so far. The aim of this study is to investigate the effect of radioactivity on the autosterilization process of radiopharmaceuticals. The study was carried out by adding Tc-99m of various radioactivity into non-sterile tetrofosmin kits, then the samples were tested for sterility. Sterile tetrofosmin kit and non-sterile kit with no Tc-99m added will be used as a negative control and positive control respectively. The sterility was tested using standard direct inoculation method, by inoculating samples in culture media for both bacteria and fungi and observing qualitatively within 14 days. The results showed that the samples with radioactivity of 1, 3 and 5 mCi changed the clarity of the media to turbid, conformed with the performance of positive controls but samples with radioactivity of 10 mCi and 20 mCi did not change the clarity of the media, conformed with the performance of negative control, indicating neither growth of bacteria nor fungi. It is concluded that Tc-99m behaves as an autosterilizing agent at certain radioactivity. Therefore the preparation of Tc-99m radiopharmaceutical can be considered as terminal sterilization rather than aseptic preparation.

    Hot axial and hot isostatic pressing was applied for single-core MgB 2 /Ti tapes. Differences in transport current density, n-exponents and critical current anisotropy are discussed and related to the grain connectivity influenced by pressing. The magnetic Hall probe scanning measurements allowed observing the isolated regions for axially hot pressed sample attributed to the longitudinally oriented cracks introduced by pressing. The highest current densities were measured for the tape subjected to hot isostatic pressing due to improved connectivity.

    In the aftermath of the A/H1N1 pandemic, health authorities were criticized for failures in crisis communication efforts, and the media were accused of amplifying the pandemic. Considering these criticisms, A/H1N1 provides a suitable case for examining risk amplification processes that may occur in the transfer of information from press releases to print news media during a health crisis. We integrated the social amplification of risk framework with theories of news decisions (news values, framing) in an attempt to contribute to existing research both theoretically and empirically. We conducted a quantitative content analysis of press releases disseminated by health and governmental authorities, as well as the quality and tabloid press in 10 European countries between March 2009 and March 2011. Altogether 243 press releases, 1,243 quality press articles, and 834 tabloid press articles were coded. Consistent with research on news values and framing the results suggest that quality and tabloid papers alike amplified A/H1N1 risks by emphasizing conflict and damage, presenting information in a more dramatized way, and using risk-amplifying frames to a greater extent and risk-attenuating frames to a lesser extent than press releases. To some extent, the quality and tabloid press differed in how risk information was presented. While tabloid press articles seemed to follow the leading quality press with regards to content and framing of health crisis coverage, they exhibited a stronger emphasis on drama and emotion in the way they presented information. © 2017 Society for Risk Analysis.
