    Fatty liver dystrophy (fld) is an autosomal recessive mutation in mice characterized by hypertriglyceridemia and development of a fatty liver in the early neonatal period. Also associated with the fld phenotype is a tissue-specific deficiency in the expression of lipoprotein lipase and hepatic lipase, as well as elevations in hepatic apolipoprotein A-IV and apolipoprotein C-II mRNA levels. Although these lipid abnormalities resolve at the age of weaning, adult mutant mice exhibit a peripheral neuropathy associated with abnormal myelin formation. The fatty liver in fld/fld neonates is characterized by the accumulation of large triglyceride droplets within the parenchymal cells, and these droplets persist within isolated hepatocytes maintained in culture for several days. To identify the metabolic defect that leads to lipid accumulation, the authors investigated several aspects of cellular triglyceride metabolism. The mutant mice exhibited normal activity of acid triacylglycerol lipase, an enzyme thought to be responsible for hydrolysis of dietary triglycerides in the liver. Metabolic labeling studies performed with oleic acid revealed that free fatty acids accumulate in the liver of 3 day old fld/fld mice, but not in adults. This accumulation in liver was mirrored by elevated free fatty acid levels in plasma of fld/fld neonates, with levels highest in very young mice and returning to normal by the age of one month. Quantitation of fatty acid oxidation in cells isolated from fld/fld neonates revealed that oxidation rate is reduced 60% in hepatocytes and 40% in fibroblasts; hepatocytes from adult fld/fld mice exhibited an oxidation rate similar to those from wild-type mice.

    Full Text Available Nation, ’ethnic people’ (das Volk, religion and the church as ellipse of reconciling diversity. This article examines the 19th and 20th century European context wherein religion was practiced. In a ‘Rip-Van-Winkle’ manner it is as if this context had no influence on the Afrikaans speaking church in South Africa. The isolation, that was the result of the apartheid ideology, lead to the Afrikaans speaking church in South Africa not internalising ecumenicity. It is argued that for the church to be able to take an active role in reconciling diversity and therefore contributing to social cohesion in South Africa, the church needs to transcend being a ‘nation’ church. This is possible by respecting culture and diversity, while recognising the priority of salvation in Christ. This is the ellipse of being church.

    We reported the experience of hemophilia camps which was accomplished with patients from hospitals of the Instituto Mexicano del Seguro Social. The aim was to prepare the families and patients regarding the disease treatment, in order to promote the self sufficiency and to know the impact of the program on the course of the disease. Surveys were applied about treatment items and personal opinions were collected. The results of the national hemophilia camp were: group of 56 patients, average 14 years, 2 % women, 51 % severe hemophilia and 43 % had hemophilic brothers. Benefits: patients increased their knowledge about earlier bleeding identification and the self-infusion method; they became aware on their responsibility in self care, timely treatment and duties at home. Hemophilia camps with patients are an option for attitude change before disease complications. Social network creation and the increase in self-sufficiency are other benefits.

  7. Characterization of a new mutant allele of the Arabidopsis Flowering Locus D (FLD) gene that controls the flowering time by repressing FLC

    2005-01-01

    Flowering in higher plants is controlled by both the internal and environmental cues. In Arabidopsis, several major genetic loci have been defined as the key switches to control flowering. The Flowering Locus C (FLC) gene has been shown in the autonomous pathway to inhibit the vegetative-to-reproductive transition. FLC appears to be repressed by Flowering Locus D (FLD), which encodes a component of the histone deacetylase complex. Here we report the identification and characterization of a new mutant allele fld-5. Genetic analysis indicates that fld-5 (in the Wassilewskija background) is allelic to the previously characterized fld-3 and fld-4 (in the Colombia-0 background). Genetic and molecular analyses reveal that fld-5 carries a frame-shift mutation, resulting in a premature termination of the FLD open reading frame. The FLC expression is remarkably increased in fld-5, which presumably attributes to the extremely delayed flowering phenotype of the mutant.

  8. Agrobacterium Mediated Transformation of Fld and GUS Genes into Canola for Salinity Stress

    Niapour, Nazila

    2013-04-01

    Full Text Available Salinity is one of the major abiotic stress which limits wide spread canola cultivation. One way to overcome this problem could be transfection, to produce tolerable species. Cotyledonary and hypocotyls explants obtained from 4 and 7 days old seedling of Elite and RJS003 varieties were utilized in this study. Genetic transformation was implemented through Agrobacterium tumefaciens LBA4404 containing PBI121 plasmid and Agrobacterium tumefaciens C58, LBA4404, AGL0 and EHA 101 strains which contain P6u- ubi- fvt1 construct. The T-DNA region of P6u- Ubi- Fvt1 plasmid included HPT (Hygromycin phosphotransferase plant selectable marker and Fld (flavodoxin gene. PBI121 plasmid had NptII (Neomycin phosphotransferase plant Selectable marker and β-glucuronidase (GUS reporter genes. Transfected explants were analyzed by PCR and histochemical assay for Fld and Gus genes, respectively. Our data indicated that the cotyledonary explants of both cultivars were incompetent to be infected with Fld gens. However, the transformation in Elite hypocotyls explants with Agrobacterium tumefaciens C58 and LBA 4404 strains were confirmed through PCR product and histochemical evaluation for Fld and GUS genes, respectively. Therefore, the result of this manuscript may to certain degree fulfill the endeavor appointed to this oilseed.

    A fast method was optimized and validated for simultaneous trace determination of four polycyclic aromatic hydrocarbons: benzo[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene and benzo[a]pyrene in bovine tissues. The determination was performed by matrix solid-phase dispersion (MSPD) coupled on-line to solid phase extraction (SPE) and high performance liquid chromatography (HPLC) with fluorescence detection (FLD). The sample was dispersed on C18 silica sorbent and then the on-line MSPD-SPE-HPLC/FLD method was applied. Several parameters were optimized: cleaning and elution sequences applied to the MSPD cartridge, the flow rate and dilution of extract used for SPE loading. The on-line method was validated over a concentration range of 0.1-0.6ngg(-1) obtaining good linearity (r⩾0.998) and precision (RSD)⩽10%. Recovery ranged from 96 to 99% and the limits of detection were 0.012ngg(-1). This methodology was applied to liver samples from unhealthy animals. The results demonstrate that MSDP-SPE-HPLC/FLD method provides reliable, sensitive, accurate and fast data to the food control.

  10. Lesbian camp: An unearthing.

    Nielsen, Elly-Jean

    2016-01-01

    Camp-a sensibility, a style, and a form of artistic self-expression-is an elusive concept said to be in the eye of the beholder. To refute Susan Sontag's ( 1966 ) claims that camp is apolitical and not especially homosexual, a number of recent scholarly works have been geared toward revealing camp's fundamental gayness. With the odd footnote aside, lesbian camp has been collapsed into the category of gay male camp, if not eclipsed entirely. Despite the negligible efforts made to legitimize lesbian camp, there are numerous salient cultural examples one might draw on to illustrate, typify, and substantiate a lesbian camp sensibility. I lay the ground work for this scholarly exercise by outlining various definitions and critiques of camp, and by discussing its history and application to queer theory. Then, to unveil lesbian camp, three non-mutually exclusive categories are discussed: classic, erotic, and radical. By gathering various strands of inquiry, and various textual examples (e.g., photography, artistic performances, and literary tropes), this article attempts to reach a more inclusive and nuanced understanding of lesbian camp.

    Different from the popular positivism and racism based on the biology claimed by Nazi scholars , Heidegger considered the nature of Volk ( the nation) from the ontological perspective.The nation means one kind of existent state when people return their nature and live with others being destiny -related.The nation came into being not automatically or historically but depending on people's decision.The artistic activities have important significance in awaking people's awareness of the nation and the forming of a nation .%不同于流行的实证主义,尤其不同于纳粹学者建立在生物学基础上的种族主义,海德格尔对民族本质的思考,着眼于其存在论的内涵。民族一方面是人返回其本质时的一种生存状态,同时也是与他人在一个共同体内命运相关的生存状态。这个意义上的民族不是自然而然形成的,而有赖于人的决断。艺术活动在唤醒人的民族意识或使得民族成其自身的过程中具有重要意义。

  5. Quantitative determination of quinolones residues in milk by HPLC-FLD

    Directory of Open Access Journals (Sweden)

    Marilena Gili

    2012-10-01

    Full Text Available Veterinary drugs have become an integral part of the livestock production and play an important role in maintenance of animal welfare. The use of veterinary medicines may be cause of the presence of drug residues in animal food products if appropriate withdrawal periods are not respected or if contaminated feeds are used. This work presents the development of an HPLC-FLD method for the quantitative de-tection of eight quinolones – norfloxacin, ciprofloxacin, danofloxacin, enrofloxacin, difloxacin, oxolinic acid, nalidixic acid, flumequine– in bovine milk. After deproteination and extraction with a metaphos-phoric acid 1% w/v / methanol / acetonitrile (60/20/20 v/v/v solution, the sample is partially evaporated and cleaned up on a reversed phase SPE cartridge.The extract is analyzed using an high performance liquid chromatograph with fluorescence detector. Mean recovery ranged between 65% - 88%. All the an-alytes can be identified and quantified in the concentration range 15 - 60 μg/Kg for danofloxacin and 25 - 150 μg/Kg for the other quinolones.

    2015-01-23

    This paper describes a selective and ultra-sensitive analytical method for simultaneous determination of 11 fluoroquinolone (FQ) antibiotics in environmental and wastewater samples. The method employs offline solid-phase extraction (SPE) and reversed-phase high performance liquid chromatography with fluorescence detection (HPLC-FLD). A weak cation exchange SPE protocol was developed with a novel loading volume optimization algorithm and a methanol cleanup step to remove background organic matter. Various parameters were optimized to recover FQs from water/wastewater and analyte recovery was generally greater than 80%. Chromatographic separation of the 11 FQs was achieved on a 150 mm pentafluorophenyl column using a gradient elution scheme with methanol, acetonitrile, and 20mM phosphate buffer (pH=2.4). Excitation and emission wavelengths were individually optimized for each FQ using fluorescence spectroscopy; the excitation and emission wavelengths were 276-296 nm and 444-506 nm, respectively. Instrumental quantitation limits were 20-100 pg of mass injected. Of the 11 FQs investigated, seven (i.e., ciprofloxacin, difloxacin, enrofloxacin, fleroxacin, norfloxacin, moxifloxacin, and ofloxacin) were detected during a four-month sampling campaign of wastewater and wastewater-impacted surface water. Concentrations of FQs in raw wastewater, wastewater effluent, and wastewater-impacted surface water were 5-1292, 2-504, and 4-187ng/L, respectively. Copyright © 2014 Elsevier B.V.

    Full Text Available According to the latest statistics, grapes are one of the largest fruit crops worldwide. In this regard, it is important to consider all factors influencing quality of grapes and wine. In the last years, scientist focused on the study of mycotoxins that can influence the quality of wine. It is considered that toxins produced by moulds, causing significant economic losses, affect approximately one quarter of the world grape production. If the selective sorting of infected grapes is not done adequately, wine will present a major risk to consumers, mycotoxins being considered by the “International Agency for Cancer Research” a carcinogenic compound. The main mycotoxins monitored in this study come from Aspergillus sp., and are represented by aflatoxins B1, B2, G1, G2 and ochratoxin A. This study purpose is to develop a faster method for the analysis of mycotoxins, in order to increase rapidity and efficiency for the evaluation of the degree of infestation in wine. The purposed method is using an on-line large volume injection coupled to pre-concentration of sample (SPE which is directly transfer to the ultra-high-pressure liquid chromatography (UHPLC column for separation and the detection by means of the fluorescence detector (FLD. As the maximum tolerated level for mycotoxins in wines is 2 ppm, this method is able to detect under this limits of quantification with RSD below 2%.

    1991-01-01

    Full Text Available Church and nation In this essay the relationship between the church and the nation, is once more investigated. It has become necessary in the light of the fact that the concept of ‘nation’ is being treated more and more negatively, especially in the ecumenical theology of mission and the struggle against apartheid in South Africa. The background to this negative attitude is not only the racial situation in South Africa, but also the experiences of church and theology in Nazi Germany. The conclusion at which the author arrives, is that, because of its assosiation with apartheid in South Africa, the word ‘nation’ has became more and more a curse. This attutude is irresponsible, and not in line with biblical thought.

    The Dorothy Ebersbach Academic Center for Flight Nursing in Cleveland, OH, holds an annual flight camp designed for master's degree nursing students in the acute care nurse practitioner program, subspecializing in flight nursing at the Frances Payne Bolton School of Nursing at Case Western Reserve University. The weeklong interprofessional training is also open to any health care provider working in an acute care setting and focuses on critical care updates, trauma, and emergency care within the critical care transport environment. This year, 29 graduate nursing students enrolled in a master's degree program from Puerto Rico attended. Although the emergency department in Puerto Rico sees and cares for trauma patients, there is no formal trauma training program. Furthermore, the country only has 1 rotor wing air medical transport service located at the Puerto Rico Medical Center in San Juan. Flight faculty and graduate teaching assistants spent approximately 9 months planning for their participation in our 13th annual flight camp. Students from Puerto Rico were extremely pleased with the learning experiences at camp and expressed particular interest in having more training time within the helicopter flight simulator.

    Full Text Available A comprehensive evaluation of the recently developed Fraunhofer line depth (FLD and laser-induced saturation pulse (FLD-LISP method was conducted to measure chlorophyll fluorescence (ChlF parameters of the quantum yield of photosystem II (ΦPSII, non-photochemical quenching (NPQ, and the photosystem II-based electron transport rate (ETR in three plant species including paprika (C3 plant, maize (C4 plant, and pachira (C3 plant. First, the relationships between photosynthetic photon flux density (PPFD and ChlF parameters retrieved using FLD-LISP and the pulse amplitude-modulated (PAM methods were analyzed for all three species. Then the relationships between ChlF parameters measured using FLD-LISP and PAM were evaluated for the plants in different growth stages of leaves from mature to aging conditions. The relationships of ChlF parameters/PPFD were similar in both FLD-LISP and PAM methods in all plant species. ΦPSII showed a linear relationship with PPFD in all three species whereas NPQ was found to be linearly related to PPFD in paprika and maize, but not for pachira. The ETR/PPFD relationship was nonlinear with increasing values observed for PPFDs lower than about 800 μmol m−2 s−1 for paprika, lower than about 1200 μmol m−2 s−1 for maize, and lower than about 800 μmol m−2 s−1 for pachira. The ΦPSII, NPQ, and ETR of both the FLD-LISP and PAM methods were very well correlated (R2 = 0.89, RMSE = 0.05, (R2 = 0.86, RMSE = 0.44, and (R2 = 0.88, RMSE = 24.69, respectively, for all plants. Therefore, the FLD-LISP method can be recommended as a robust technique for the estimation of ChlF parameters.

    During the month of July, the Staff Association’s Children’s Day-Care Centre and School EVEE held a summer camp for 4- to 6-year-olds. 24 children altogether joined in on the adventures. On the summer camp, the children got to “travel” to a different continent of the world every week. Day after day, they would pass through make-believe Customs upon arrival and get their passports stamped by a “customs officer”. For the first week, we went on a trip to Africa. In the spirit of the theme, the children got to do plenty of crafts and coloring, make their own little bindles and play various games. They even had the chance to visit the Museum of Ethnography in Geneva (MEG), learn to play the balafon and make musical instruments with Sterrenlab. For the second week, we set off to discover the Americas, exploring both the South and the North. Alongside different workshops (singing, dancing, storytelling, crafts), the children could enjoy several special ac...

    Full Text Available The purpose of this study was twofold. First, the study sought to better understand the work motivators that led camp supervisors and counselors to accept their job. Second, the study sought to better understand the ranking and rating of 20 work motivators from supervisors and camp counselors. Responders to the research questionnaire (n=121 were camp supervisory staff and counselors, age 15-55, working in seven private camps in Greece. Two instruments were used to collect data. The first instrument collected demographic data while the second instrument focused on ranking and rating 20 work motivators. The study suggested that Herzberg's theory (Motivator / Hygiene does not apply on a full scale. The results suggested that supervisory staff indicated good working conditions, meeting other people and carrying out personal growth are important. In addition, they don't like travel and don't consider working in a camp, as a stable job. The camp counselors want to have fun in their job and the opportunity to work with youth. They also don't consider working in a camp, as a stable job and they don't accept the responsibility in proportion to their position.

  4. Base Camp Architecture

    2016-03-01

    Full Text Available Longitudinal or time line studies of change in the architecture of a particular culture are common, but an area still open to further research is change across space or place. In particular, there is need for studies on architectural change of cultures stemming from the same ethnic source split between their homeland and other Diasporas. This change may range from minor deviations to drastic shifts away from an architectural norm and the accumulation of these shifts within a time frame constitutes variations. This article focuses on identifying variations in the architecture of the Ijo fishing group that migrates along the coastline of West Africa. It examines the causes of cross-cultural variation between base camp dwellings of Ijo migrant fishermen in the Bakassi Peninsula in Cameroon and Bayelsa State in Nigeria. The study draws on the idea of the inevitability of cultural and social change over time as proposed in the theories of cultural dynamism and evolution. It tests aspects of cultural transmission theory using the principal coordinates analysis to ascertain the possible causes of variation. From the findings, this research argues that migration has enhanced the forces of cultural dynamism, which have resulted in significant variations in the architecture of this fishing group.

    1995-07-01

    In 1992, Bonneville Power Administration (BPA) and the US Department of Energy (DOE) began a collaborative pilot project with the Portland Parks and Recreation Community Schools Program and others to provide summer science camps to children in Grades 4--6. Camps run two weeks in duration between late June and mid-August. Sessions are five days per week, from 9 a.m. to 3 p.m. In addition to hands-on science and math curriculum, at least three field trips are incorporated into the educational learning experience. The purpose of the BPA/DOE summer camps is to make available opportunities for fun, motivating experiences in science to students who otherwise would have difficulty accessing them. This includes inner city, minority, rural and low income students. Public law 101-510, which Congress passed in 1990, authorizes DOE facilities to establish collaborative inner-city and rural partnership programs in science and math. A primary goal of the BPA summer hands on science camps is to bring affordable science camp experiences to students where they live. It uses everyday materials to engage students` minds and to give them a sense that they have succeeded through a fun hands-on learning environment.

    Twenty-four samples including 14 functional foods and 10 spices obtained from Chinese markets were examined for their mould profile. The mycotoxin contamination levels were also determined by an optimized HPLC-FLD method. 124 fungal isolates belonging to four different genera were recovered with Aspergillus and Penicillium as predominant fungi, with an incidence of 66.1% and 15.3%, respectively. In functional foods Aspergillus niger section (57.1%) was isolated more frequently, followed by Aspergillus flavi section (50.0%) and Aspergillus ochraceus section (21.4%), with the most contaminated samples being Coix seeds. Similar fungal presence and frequency were encountered in spice with A. niger section group (60.0%) and A. flavi section (40.0%) as main fungi. Cumin and Pricklyash peel samples showed the highest fungal contamination. Four functional foods and three spices were found to be positive at low levels for mycotoxins including aflatoxin B1 (up to 0.26μg/kg) and ochratoxin A (OTA) (5.0μg/kg). The more frequently detected mycotoxin was AFB1 (16.7%).

    2016-05-15

    The determination of flavonoid compounds in paprika samples has been performed by liquid chromatography in series diode array and fluorescence detection (LC-DAD-FLD), by means of a pH change to basic medium just before FLD detection. The validation of the method was performed through the establishment of the external standard calibration curves and the analytical figures of merit. Limits of detection ranging from 0.006 to 0.02 mg L(-1) and 0.007 to 0.09 mg L(-1) were achieved using DAD and FLD detection, respectively. The experimental conditions to carry out the hydrolysis procedure to obtain flavonoid aglycones from flavonoid glycosides have been optimized applying an experimental design and the response surface methodology. The final conditions selected were 2.5M HCl during 45 min at 85°C. The repeatability of this procedure was assayed and relative standard deviation (RSD) values for concentration of quercetin and luteolin compounds were lower than 2%. The quantification of quercetin, luteolin and kaempferol compounds was carried out in less than 6 min in paprika samples by means of the external standard calibration. The analytes were extracted with methanol and the extracts were previously subjected to a cleanup procedure to extend the use of the chromatographic column.

  16. Improved Quantitation of Gluten in Wheat Starch for Celiac Disease Patients by Gel-Permeation High-Performance Liquid Chromatography with Fluorescence Detection (GP-HPLC-FLD).

    Scherf, Katharina Anne; Wieser, Herbert; Koehler, Peter

    2016-10-12

    Purified wheat starch (WSt) is commonly used in gluten-free products for celiac disease (CD) patients. It is mostly well-tolerated, but doubts about its safety for CD patients persist. One reason may be that most ELISA kits primarily recognize the alcohol-soluble gliadin fraction of gluten, but insufficiently target the alcohol-insoluble glutenin fraction. To address this problem, a new sensitive method based on the sequential extraction of gliadins, glutenins, and gluten from WSt followed by gel-permeation high-performance liquid chromatography with fluorescence detection (GP-HPLC-FLD) was developed. It revealed that considerable amounts of glutenins were present in most WSt. The gluten contents quantitated by GP-HPLC-FLD as sum of gliadins and glutenins were higher than those by R5 ELISA (gluten as gliadin content multiplied by a factor of 2) in 19 out of 26 WSt. Despite its limited selectivity, GP-HPLC-FLD may be applied as confirmatory method to ELISA to quantitate gluten in WSt.

    Full Text Available Film and television are popular media for the (representation of history and the depiction of momentous past events. Germany’s reunification is no exception. After the fall of the Berlin Wall, Germany has witnessed a proliferation of media production that endeavors to historicize and aestheticize the past. This coincides with the need to forge a post-Wall identity of the new Germany. My discussion of Thomas Berger’s award winning television drama Wir sind das Volk. Liebe kennt keine Grenzen (2008 examines how reunification is presented in a mixture of fictitious elements and authentic historical reconstruction based on shared memories of this past. Following a melodramatic trajectory, the film aims at the reconciliation of German society as a people twenty years after reunification.

    2012-01-01

    Historically, when mounting expeditions into uncharted territories, explorers have established strategically positioned base camps to pre-position required equipment and consumables. These base camps are secure, safe positions from which expeditions can depart when conditions are favorable, at which technology and operations can be tested and validated, and facilitate timely access to more robust facilities in the event of an emergency. For human exploration missions into deep space, cis-lunar space is well suited to serve as such a base camp. The outer regions of cis-lunar space, such as the Earth-Moon Lagrange points, lie near the edge of Earth s gravity well, allowing equipment and consumables to be aggregated with easy access to deep space and to the lunar surface, as well as more distant destinations, such as near-Earth Asteroids (NEAs) and Mars and its moons. Several approaches to utilizing a cis-lunar base camp for sustainable human exploration, as well as some possible future applications are identified. The primary objective of the analysis presented in this paper is to identify options, show the macro trends, and provide information that can be used as a basis for more detailed mission development. Compared within are the high-level performance and cost of 15 preliminary cis-lunar exploration campaigns that establish the capability to conduct crewed missions of up to one year in duration, and then aggregate mass in cis-lunar space to facilitate an expedition from Cis-Lunar Base Camp. Launch vehicles, chemical propulsion stages, and electric propulsion stages are discussed and parametric sizing values are used to create architectures of in-space transportation elements that extend the existing in-space supply chain to cis-lunar space. The transportation options to cis-lunar space assessed vary in efficiency by almost 50%; from 0.16 to 0.68 kg of cargo in cis-lunar space for every kilogram of mass in Low Earth Orbit (LEO).

    This document presented a case study of the use of solar power at camp Tanamakoon in Ontario's Algonquin Park. It discussed camp facilities which include solar powered composting toilets and solar heated showers. Composting, recycling, and use of environmentally friendly products were also discussed. The camp also has a grid interactive solar electric system and a solar water heating system. The solar electric system provides backup power to critical loads such as safety lights and an emergency fridge and is also connected to the existing grid electricity system. Any excess energy from the solar system can be used by other kitchen appliances or, any other load anywhere in the camp. The main user of the solar heated water is a large automatic dishwasher which has as a built-in boost heater for those days when the solar heated water is insufficiently hot to sanitize dishes. It was concluded that while camp utility bills have been reduced by this investment in renewable energy technology, the primary objectives of the project were the protection of Tanamakoon's pristine Algonquin environment and the attraction and retention of clients for the camp by enhancing the camping experience. fig.

    A novel approach of periodate oxidation coupled with high-performance liquid chromatography (HPLC)-fluorescence detection (FLD) for the quantitative determination of 3-chloro-1,2-propanediol (3-MCPD) has been established. The essence of this approach lies in the production of chloroacetaldehyde by the oxidization cleavage of 3-MCPD with sodium periodate and the HPLC analysis of chloroacetaldehyde monitored by an FLD detector after fluorescence derivatization with adenine. The experimental parameters relating to the efficiency of the derivative reaction such as concentration of adenine, chloroacetaldehyde reaction temperature, and time were studied. Under the optimized conditions, the proposed method can provide high sensitivity, good linearity (r(2) = 0.999), and repeatability (percent relative standard deviations between 2.57% and 3.44%), the limits of detection and quantification were 0.36 and 1.20 ng/mL, respectively, and the recoveries obtained for water samples were in the range 93.39-97.39%. This method has been successfully applied to the analysis of real water samples. Also this method has been successfully used for the analysis of vegetable oil samples after pretreatment with liquid-liquid extraction; the recoveries obtained by a spiking experiment with soybean oil ranged from 96.27% to 102.42%. In comparison with gas chromatography or gas chromatography-mass spectrometry, the proposed method can provide the advantages of simple instrumental requirement, easy operation, low cost, and high efficiency, thus making this approach another good choice for the sensitive determination of 3-MCPD.

    In this article, dispersive liquid-liquid microextraction (DLLME), based on the use of so-called switchable polarity dispersive solvent (SPDS) for microextraction, is presented for the first time. The new extraction technique makes use of a mixture of extraction solvent (dichloromethane) and the SPDS (acrylic acid). This mixture is injected into the aqueous sample solution, which was previously fortified with the alkaline agent (NaOH). The SPDS is dissolved in aqueous phase and a cloudy solution consisting of fine droplets of extraction solvent fully dispersed in the aqueous phase is observed. Simultaneously, as a consequence of the fast neutralization reaction, the SPDS investigated is converted into water-soluble salt and phase separation is achieved because the SPDS switches its polarity. Conversion of the SPDS excludes the negative influence of the conventional dispersive solvents used in DLLME on the solubility of target analytes in aqueous phase and, as a result, increases the DLLME efficiency. The proposed extraction technique was automated based on a flow system and coupled with high performance liquid chromatography system with fluorescence detection (HPLC-FLD) and demonstrated by the determination of ofloxacin (OFLX) in chicken meat samples. This analytical task was used as a proof-of-concept example. The automated method includes on-line ultrasound assisted solid-liquid extraction of OFLX from chicken meat samples followed by DLLME using SPDS, solvent exchange and the determination by HPLC-FLD. Under the optimal conditions, the detector response for OFLX was linear in concentration range of 6·10(-9) - 5·10(-7) mol L(-1). The limit of detection, calculated from a blank test based on 3σ, was 2·10(-9) mol L(-1).

    Blas, Howard I

    2007-10-01

    The Tikvah Program is an overnight camping program at Camp Ramah in New England that serves campers with a range of developmental disabilities. The program has evolved over its 37-year history and includes a camping program, vocational training program, and inclusion program. Select graduates are hired by the camp for summer employment. The Tikvah Program offers a model for serving campers with special needs within a larger "typical" summer camp. Although serving the needs of such campers offers unique challenges, the presence of such a program in a regular summer camp offers tremendous opportunities and benefits for campers with special needs and more typically developing campers.

    Approximately one fifth of school-aged children spend a significant portion of their year at residential summer camp, and a growing number have chronic medical conditions. Camp health records are essential for safe, efficient care and for transitions between camp and home providers, yet little research exists regarding these systems. To survey residential summer camps for children to determine how camps create, store, and use camper health records. To raise awareness in the informatics community of the issues experienced by health providers working in a special pediatric care setting. We designed a web-based electronic survey concerning medical recordkeeping and healthcare practices at summer camps. 953 camps accredited by the American Camp Association received the survey. Responses were consolidated and evaluated for trends and conclusions. Of 953 camps contacted, 298 (31%) responded to the survey. Among respondents, 49.3% stated that there was no computer available at the health center, and 14.8% of camps stated that there was not any computer available to health staff at all. 41.1% of camps stated that internet access was not available. The most common complaints concerning recordkeeping practices were time burden, adequate completion, and consistency. Summer camps in the United States make efforts to appropriately document healthcare given to campers, but inconsistency and inefficiency may be barriers to staff productivity, staff satisfaction, and quality of care. Survey responses suggest that the current methods used by camps to document healthcare cause limitations in consistency, efficiency, and communications between providers, camp staff, and parents. As of 2012, survey respondents articulated need for a standard software to document summer camp healthcare practices that accounts for camp-specific needs. Improvement may be achieved if documentation software offers the networking capability, simplicity, pediatrics-specific features, and avoidance of

  16. Sesamin and sesamolin as unexpected contaminants in various cold-pressed plant oils: NP-HPLC/FLD/DAD and RP-UPLC-ESI/MS(n) study.

    Science.gov (United States)

    Górnaś, Paweł; Siger, Aleksander; Pugajeva, Iveta; Segliņa, Dalija

    2014-04-01

    Thirteen cold-pressed oils (Japanese quince seed, black caraway, flaxseed, rapeseed, hemp, peanut, sunflower, pumpkin, hazelnut, poppy, walnut, almond and sesame oil) manufactured by the same company over a 2-year period (2011-12) were assessed for lipophilic compounds. The presence of sesamin and sesamolin, two characteristic lignans of sesame oil, were detected in all tested plant oils. Both lignans were identified by NP-HPLC/FLD/DAD and confirmed by a RP-UPLC-ESI/MS(n) method. The lowest amount of sesamin and sesamolin was found for Japanese quince seed oil (0.10 and 0.27 mg/100 g), and the highest, excluding sesame oil, for almond oil (36.21 and 105.42 mg/100 g, respectively). The highly significant correlation between sesamolin and sesamin concentrations was found in all samples tested (r = 0.9999; p < 0.00001). These results indicate contamination of cold-pressed oils from the same source. This investigation highlights the fact that increasing the range of products manufactured by the same company can contribute to a lesser regard for the quality of the final product. Moreover, less attention paid to the quality of final product can be related to the health risks of consumers especially sensitive to allergens. Therefore, proper cleaning of processing equipment is needed to prevent cross-contact of cold-pressed oils.

    2015-11-01

    A sensitive, stereoselective assay using solid phase extraction and high-performance liquid chromatography (HPLC) with fluorescence detection (FLD) was developed and validated for the analysis of enantiomers of metoprolol and its metabolites (α-hydroxymetoprolol, O-desmethylmetoprolol). Chiral separation was achieved using a CHIRALCEL OD-RH column, packed with cellulose tris-(3,5-dimethylphenyl-carbamate) stationary phase, employing a mobile phase composed by a mixture of 0.2% diethylamine in water and acetonitrile in gradient elution mode. Linear calibration curves were obtained over the range of 0.025-2.0μg/mL (R(2)>0.994) in urine for both enantiomers of metoprolol and its metabolites with quantitation limit of 0.025μg/mL. Intra and inter-day precision and accuracy were below 15% for both metoprolol and metabolites enantiomers. The recovery of enantiomer of metoprolol and its metabolite was greater than 68.0%, utilizing a SPE procedure. The method was tested with urine quality control samples and human urine fractions after administration of 50mg rac-metoprolol.

    Maslow, Gary R; Lobato, Debra

    2010-01-01

    The first summer camps for children with burn injuries started over 25 years ago, and as of 2008, there were 60 camps worldwide. This review examines the literature on summer pediatric burn camps. The authors describe common characteristics of burn camp structure, activities, and staffing and then examine the scientific evidence regarding the effect of burn camp programs on campers and camp staff volunteers. A search of Pubmed and Psychinfo databases from 1970 to 2008 for articles related to pediatric burn summer camps identified 17 articles, of which 13 fit the inclusion criteria. Existing literature consists primarily of qualitative studies, suggesting that burn camp can decrease camper isolation, improve self-esteem, and promote coping and social skills. Studies examining volunteer staff at burn camp have consistently found that there are both personal and professional benefits. Quantitative studies of self-esteem have yielded equivocal results. No studies have examined safety or the effect of burn camp on medical or rehabilitation outcomes. For the past 25 years, pediatric summer camps for children with burn injuries have played an important rehabilitation role and provided a strong community that benefits both campers and staff. Future research using more rigorous research methods and examining a broader range of outcomes (eg, safety and medical/rehabilitation outcomes) is recommended.

    2015-04-01

    Full Text Available Camps are a great introduction to the sport of basketball for children. Universities and colleges usually offer different types of camps, typically during the summer months. Depending on the skill and maturity level of the player, basketball camps can serve a variety of purposes. Some popular types of camps include offensive skills, shooting, team, and youth camps. Regardless of the camp that is chosen, children need to have goals set for themselves before, during, and after to enhance the benefits. Each camper should have the opportunity to grow and develop as a basketball player as well as an individual. Running a successful camp is not only rewarding for the coaches, but for the players and campers too, which ultimately leads to the campers choosing to come back every year.

    Orthopedic surgical interns must gain a broad array of clinical skills in a short time. However, recent changes in health care have limited resident-patient exposures. With the reported success of simulation training in the surgical literature, the American Board of Orthopaedic Surgery (ABOS) and Residency Review Committee for Orthopaedic Surgery have required that surgical simulation training be a component of the intern curricula in orthopedic surgical residencies. This study examined the short-term effectiveness of an orthopedic "intern boot camp" covering 7 of 17 simulation training concept modules published by the ABOS. Eight orthopedic post-graduate year 1 (PGY-1) residents (study group) completed a structured 3-month curriculum and were compared with 7 post-graduate year 2 (PGY-2) residents (comparison group) who had just completed their orthopedic surgical internship. Seven core skills were assessed using both task-specific and global rating scales. The PGY-1 residents demonstrated a statistically significant improvement in all 7 modules with respect to their task-specific pre-test scores: sterile technique (P=.001), wound closure (P<.001), knot tying (P=.017), casting and splinting (P<.001), arthrocentesis (P=.01), basics of internal fixation (P<.001), and compartment syndrome evaluation (P=.004). After the camp, PGY-1 and -2 scores in task-specific measures were not significantly different. A 3-month simulation-based boot camp instituted early in orthopedic internship elevated a variety of clinical skills to levels exhibited by PGY-2 residents.

    CAMP test reliably detects Listeria monocytogenes (Lm) and Streptococcus agalactiae (group B streptococcus, GBS); it is traditionally performed streaking the tested isolate perpendicularly to Staphylococcus aureus (Sa), provided that reference Sa strains (that produce β-hemolysin) are used. In a zone of β-hemolysin activity, in fact, GBS and Lm form typical arrow-shaped hemolytic areas. While Sa production of the toxin is strain-dependent, however, that of Staphylococcus pseudintermedius (Sp), a pet-owner colonizer and an emerging human pathogen, is constitutive, then observed in all clinical isolates. Therefore, Sp may indeed represent a valid alternative to perform the assay.

    2014-04-01

    Full Text Available Ochratoxin A (OTA is a mycotoxin produced by different Aspergillus and Penicillium species. Since its mechanism of action is not fully understood yet, it is important to gain further insight into different interactions of OTA at the molecular level. OTA is found worldwide in many foods and drinks. Moreover, it can also be detected in human and animal tissues and body fluids, as well. Therefore, the development of highly sensitive quantitative methods for the determination of OTA is of utmost importance. OTA most likely forms complexes with divalent cations, both in cells and body fluids. In the present study, the OTA-zinc interaction was investigated and compared to OTA-magnesium complex formation using fluorescence spectroscopy and molecular modeling. Our results show that zinc(II ion forms a two-fold higher stable complex with OTA than magnesium(II ion. In addition, based on the enhanced fluorescence emission of OTA in its magnesium-bound form, a novel RP-HPLC-fluorescence detector (FLD method was also established. Our results highlight that the application of magnesium chloride in alkaline eluents results in an approximately two-fold increase in sensitivity using the HPLC-FLD technique.

    The Escherichia coli cAMP receptor protein (CRP) requires cAMP binding to undergo a conformational change for DNA binding and transcriptional regulation. Two CRP residues, Thr(127) and Ser(128), are known to play important roles in cAMP binding through hydrogen bonding and in the cAMP-induced conformational change, but the connection between the two is not completely clear. Here, we simultaneously randomized the codons for these two residues and selected CRP mutants displaying high CRP activity in a cAMP-producing E. coli. Many different CRP mutants satisfied the screening condition for high CRP activity, including those that cannot form any hydrogen bonds with the incoming cAMP at the two positions. In vitro DNA-binding analysis confirmed that these selected CRP mutants indeed display high CRP activity in response to cAMP. These results indicate that the hydrogen bonding ability of the Thr(127) and Ser(128) residues is not critical for the cAMP-induced CRP activation. However, the hydrogen bonding ability of Thr(127) and Ser(128) was found to be important in attaining high cAMP affinity. Computational analysis revealed that most natural cAMP-sensing CRP homologs have Thr/Ser, Thr/Thr, or Thr/Asn at positions 127 and 128. All of these pairs are excellent hydrogen bonding partners and they do not elevate CRP activity in the absence of cAMP. Taken together, our analyses suggest that CRP evolved to have hydrogen bonding residues at the cAMP pocket residues 127 and 128 for performing dual functions: preserving high cAMP affinity and keeping CRP inactive in the absence of cAMP.

    Full Text Available Camps are a great way to keep kids active throughout the summer and to make money for the program sponsoring them. Planning is needed for a sports camp to be safe for both the camp personnel and the athletes, and to minimize legal negligence.  Having a risk management plan in place is important to insure that everyone is aware of the risks of participating. Background checks on camp personnel help ensure the camp leaders and coaches do not have a criminal background.  It is important to inspect the facilities/equipment to make sure they are safe to use.  Athletic trainers help with injuries that may occur with participation.  Supervisors make sure that everyone is accounted for and camp rules help the campers behave in an appropriate manner.  When planning activities, it is important to look at the skill level of the athletes. If all of these areas are covered, camps should be legally protected if an issue were to arise.

    2008-12-01

    Full Text Available The purpose of this study was the description of sports injuries sustained by campers at summer camps, aged 7-15 years. A sample of 8 camps from the Greek camp population participated in this sport injury surveillance study. Doctors and camp directors completed reports detailing the number of sports injuries events sustained and provided specific information about each event. During the period of the study, 337 sport injury reports were completed. A total of 237 (70.3% boys and 100 (29.7% girls reported having a sport injury. Age of campers sustaining a sport injury was 10-12 years old (60.8%. The frequency of sports injuries was highest during the first camp season. The leading causes of sports injuries in children’s were: falls, crushed by object, collision with other person and slips. Cut/scratch injuries were the most common diagnoses (38.9%. Football, basketball and volleyball were the most frequent sport activities for injuries. Reports based surveillance systems can be successfully used to conducts sport injury surveillance among children attending summer camps. Data collected via such systems can be used to calculate sports injury rates, to describe patterns of sport injury and to identify risk factors for camper – related sport injuries. The results provide necessary information to develop prevention interventions to decrease the number of youth whose camp experiences are negatively affected by sport injury.

    Southam, M A; Kirkley, B G; Murchison, A; Berkowitz, R I

    1984-01-01

    Twenty-five overweight adolescents completed a summer weight loss day camp program on the Stanford University campus. All participants attended camp four days per week for four hours to learn and practice eating and exercise skills conducive to weight loss. Parents met weekly to discuss the program content and to explore their role in their adolescent's weight management. At posttreatment, reductions were achieved in weight, percent overweight, and skinfold, with greater changes observed for the eight-week group than for the four-week group. Improvements were also evident in participants' self-reported habits and knowledge of weight management concepts. Parent and participant assessment of the camp experience was very positive. The results of the summer weight loss day camp suggest that an intensive program of eating and exercise habit instruction, practice, and monitoring, which allows the participants to remain in the home setting, may provide benefits not found in other more traditional approaches to adolescent weight loss.

  18. A dynamic interface between ubiquitylation and cAMP signaling

    Directory of Open Access Journals (Sweden)

    Laura eRinaldi

    2015-09-01

    Full Text Available Phosphorylation waves drive the propagation of signals generated in response to hormones and growth factors in target cells. cAMP is an ancient second messenger implicated in key biological functions. In mammals, most of the effects elicited by cAMP are mediated by protein kinase A (PKA. Activation of the kinase by cAMP results in the phosphorylation of a variety of cellular substrates, leading to differentiation, proliferation, survival, metabolism. The identification of scaffold proteins, namely A-Kinase Anchor proteins (AKAPs, that localize PKA in specific cellular districts, provides critical cues for our understanding of the role played by cAMP in cell biology. Multivalent complexes are assembled by AKAPs and include signaling enzymes, mRNAs, adapter molecules, receptors and ion channels. A novel development derived from the molecular analysis of these complexes nucleated by AKAPs is represented by the presence of components of the ubiquitin proteasome system (UPS. More to it, the AKAP complex can be regulated by the UPS, eliciting relevant effects on downstream cAMP signals.This represents a novel, yet previously unpredicted interface between compartmentalized signaling and the UPS. We anticipate that impairment of these regulatory mechanisms could promote cell dysfunction and disease. Here, we will focus on the reciprocal regulation between cAMP signaling and UPS, and its relevance to human proliferative disorders.

    Full Text Available Introduction: Establishing a boot camp curriculum is pertinent for emergency medicine (EM residents in order to develop proficiency in a large scope of procedures and leadership skills.  In this article, we describe our program’s EM boot camp curriculum as well as measure the confidence levels of resident physicians through a pre- and post-boot camp survey. Methods: We designed a one-month boot camp curriculum with the intention of improving the confidence, procedural performance, leadership, communication and resource management of EM interns. Our curriculum consisted of 12 hours of initial training and culminated in a two-day boot camp. The initial day consisted of clinical skill training and the second day included code drill scenarios followed by interprofessional debriefing.   Results: Twelve EM interns entered residency with an overall confidence score of 3.2 (1-5 scale across all surveyed skills. Interns reported the highest pre-survey confidence scores in suturing (4.3 and genitourinary exams (3.9. The lowest pre-survey confidence score was in thoracostomy (2.4. Following the capstone experience, overall confidence scores increased to 4.0. Confidence increased the most in defibrillation and thoracostomy. Additionally, all interns reported post-survey confidence scores of at least 3.0 in all skills, representing an internal anchor of “moderately confident/need guidance at times to perform procedure.” Conclusion: At the completion of the boot camp curriculum, EM interns had improvement in self-reported confidence across all surveyed skills and procedures. The described EM boot camp curriculum was effective, feasible and provided a foundation to our trainees during their first month of residency. [West J Emerg Med. 2015;16(2:356–361.

  1. Revisiting cAMP signaling in the carotid body

    Ana Rita eNunes

    2014-10-01

    Full Text Available Chronic carotid body (CB activation is now recognized as being essential in the development of hypertension and promoting insulin resistance; thus, it is imperative to characterize the chemotransduction mechanisms of this organ in order to modulate its activity and improve patient outcomes. For several years, and although controversial, cyclic adenosine monophosphate (cAMP was considered an important player in initiating the activation of the CB. However, its relevance was partially displaced in the 90s by the emerging role of the mitochondria and molecules such as AMP-activated protein kinase (AMPK and O2-sensitive K+ channels. Neurotransmitters/neuromodulators binding to metabotropic receptors are essential to chemotransmission in the CB, and cAMP is central to this process. cAMP also contributes to raise intracellular Ca2+ levels, and is intimately related to the cellular energetic status (AMP/ATP ratio. Furthermore, cAMP signaling is a target of multiple current pharmacological agents used in clinical practice. This review provides an outline on 1 the classical view of the cAMP-signaling pathway in the CB that originally supported its role in the O2/CO2 sensing mechanism, 2 present recent evidence on CB cAMP neuromodulation and 3 discuss how CB activity is affected by current clinical therapies that modify cAMP-signaling, namely dopaminergic drugs, caffeine (modulation of A2A/A2B receptors and roflumilast (PDE4 inhibitors. cAMP is key to any process that involves metabotropic receptors and the intracellular pathways involved in CB disease states are likely to involve this classical second messenger. Research examining the potential modification of cAMP levels and/or interactions with molecules associated with CB hyperactivity is currently in its beginning and this review will open doors for future explorations.

    A science summer camp is a popular type of informal science experience for youth. While there is no one model of a science camp, these experiences typically allow for more focused and in-depth exploration of different science domains and are usually hands-on and participatory. The goal of this research was to examine the impact of a short science camp program approximately 1 year after students attended the camp. Overall, the results revealed that attending a 2-day forensic science camp had a positive and continuing influence on the participants. Students' science self-efficacy increased immediately after attending the camp and remained higher than pre-camp levels approximately 1 year later. Students were able to articulate why they believed the camp had a long-term impact on their lives. Furthermore, participants attributed a higher level of engaging in additional informal STEM-related activities during the academic year as a result of attending the camp.

Initially, it was thought that protein kinase A (PKA exclusively mediates cAMP-induced cellular responses such as an increase in cardiac contractility, relaxation, and heart rate. With the identification of the exchange factor directly activated by cAMP (EPAC and hyperpolarizing cyclic nucleotide-gated (HCN channels as cAMP effector proteins it became clear that a protein network is involved in cAMP signaling. The Popeye domain containing (Popdc genes encode yet another family of cAMP-binding proteins, which are prominently expressed in the heart. Loss-of-function mutations in mice are associated with cardiac arrhythmia and impaired skeletal muscle regeneration. Interestingly, the cardiac phenotype, which is present in both, Popdc1 and Popdc2 null mutants, is characterized by a stress-induced sinus bradycardia, suggesting that Popdc proteins participate in cAMP signaling in the sinuatrial node. The identification of the two-pore channel TREK-1 and Caveolin 3 as Popdc-interacting proteins represents a first step into understanding the mechanisms of heart rate modulation triggered by Popdc proteins.

    The aim of our study is to evaluate the effectiveness of newly implemented general surgery intern boot camp. A 2-day didactic and skills-based intern boot camp was implemented before the start of clinical duties. Participants who did not attend all boot camp activities and had prior postgraduate training were excluded. A survey utilizing a 5-point Likert scale scoring system was used to assess the participants' confidence to perform intern-level tasks before and after the boot camp. Subgroup analyses were performed comparing changes in confidence among graduates from home institution versus others and general surgery versus other subspecialties. In the analysis, 21 participants over two years were included. Among them, 7 were graduates from home institution (4 general surgery, 3 subspecialty) and 14 were from other institutions (6 general surgery and 8 subspecialty). There were significant increases in overall confidence levels (pre = 2.79 vs post = 3.43, P surgery (2.78 vs 3.46, P = 0.001) and other specialties (2.74 vs 3.34, P surgery intern boot camp before the start of official rotation is effective in improving confidence level in performing level-appropriate tasks of the incoming new interns.

    2013-10-01

    Full Text Available 8-Azidoadenosine 3′,5′-cyclic monophosphate (8-azido cAMP was directly detected in living cells, by applying Cu-free azide-alkyne cycloaddition to probe cAMP derivatives by fluorescence light-up. Fluorescence emission was generated by two non-fluorescent molecules, 8-azido cAMP as a model target and difluorinated cyclooctyne (DIFO reagent as a probe. The azide-alkyne cycloaddition reaction between 8-azido cAMP and DIFO induces fluorescence in 8-azido cAMP. The fluorescence emission serves as a way to probe 8-azido cAMP in cells.

    2011-06-01

    Soluble adenylyl cyclase (sAC) is a recently identified source of the ubiquitous second messenger cyclic adenosine 3',5' monophosphate (cAMP). sAC is distinct from the more widely studied source of cAMP, the transmembrane adenylyl cyclases (tmACs); its activity is uniquely regulated by bicarbonate anions, and it is distributed throughout the cytoplasm and in cellular organelles. Due to its unique localization and regulation, sAC has various functions in a variety of physiological systems that are distinct from tmACs. In this review, we detail the known functions of sAC, and we reassess commonly held views of cAMP signaling inside cells.

  8. Investigation of Sylvatic Typhus at a Wilderness Camp

    Centers for Disease Control (CDC) Podcasts

    2009-06-30

    In this podcast, Dr. Greg Dasch discusses an outbreak of four cases of sylvatic typhus that occurred at a wilderness camp in Pennsylvania. Sylvatic typhus is very rare in the United States, with only 41 cases since it was discovered in the United States in 1975. Lab work at CDC and the discovery that all four camp counselors who became ill had slept in the same bunk at the camp between 2004 and 2006 ultimately led to confirmation that flying squirrels living in the wall of the cabin were to blame for the illnesses.  Created: 6/30/2009 by Emerging Infectious Diseases.   Date Released: 6/30/2009.

    We previously demonstrated that a pediatric cardiology boot camp can improve knowledge acquisition and decrease anxiety for trainees. We sought to determine if boot camp participants entered fellowship with a knowledge advantage over fellows who did not attend and if there was moderate-term retention of that knowledge. A 2-day training program was provided for incoming pediatric cardiology fellows from eight fellowship programs in April 2016. Hands-on, immersive experiences and simulations were provided in all major areas of pediatric cardiology. Knowledge-based examinations were completed by each participant prior to boot camp (PRE), immediately post-training (POST), and prior to the start of fellowship in June 2016 (F/U). A control group of fellows who did not attend boot camp also completed an examination prior to fellowship (CTRL). Comparisons of scores were made for individual participants and between participants and controls. A total of 16 participants and 16 control subjects were included. Baseline exam scores were similar between participants and controls (PRE 47 ± 11% vs. CTRL 52 ± 10%; p = 0.22). Participants' knowledge improved with boot camp training (PRE 47 ± 11% vs. POST 70 ± 8%; p cardiology knowledge after the training program and had excellent moderate-term retention of that knowledge. Participants began fellowship with a larger fund of knowledge than those fellows who did not attend.

    2001-01-01

    Children with hemophilia have often been viewed at greater risk for altered self-esteem than their healthy counterparts. Our article shares the positive effects of the camp experience on children with hemophilia and subsequent enhancement of self-esteem. Interaction and support in the camp environment provide an opportunity for these children to gain independence and "prove" their self-worth and ability. Previous literature has provided a variety of findings on the relationship between chronic illness, such as hemophilia, and self-esteem alterations. We identify many opportunities for future education and research to provide quality nursing support to this unique population.

    1986-01-01

    In the summer of 1982, Texas Scottish Rite Hospital (Dallas, TX, U.S.A.) sponsored a camp for paraplegic adolescents. Six patients, three boys and three girls 14-17 years of age, participated in a 2-week program that was designed to improve their self-esteem, independence, and eventual employability. In their pre- and postcamp psychological evaluations, the campers demonstrated improvement in social skills and self-concept testing as compared with the scores of a matched control group, although this improvement did not reach statistical significance. We believe the camp was immensely successful, an opinion that was shared by both the campers and their parents.

  18. Seafloor Science and Remotely Operated Vehicle (SSROV) Day Camp: A Week-Long, Hands-On STEM Summer Camp

    2015-12-01

    RETINA (Robotic Exploration Technologies IN Astrobiology) has developed a program geared towards stimulating our youth with innovative and relevant hands-on learning modules under a STEM umbrella. Given the breadth of potential science and engineering topics that excite children, the RETINA Program focuses on interactive participation in the design and development of simple robotic and sensor systems, providing a range of challenges to engage students through project-based learning (PBL). Thus, young students experience scientific discovery through the use and understanding of technology. This groundwork serves as the foundation for SSROV Camp, a week-long, summer day camp for 6th-8th grade students. The camp is centered on the sensors and platforms that guide seafloor exploration and discovery and builds upon the notion that transformative discoveries in the deep sea result from either sampling new environments or making new measurements with sensors adapted to this extreme environment. These technical and scientific needs are folded into the curriculum. Each of the first four days of the camp includes four team-based, hands-on technical challenges, communication among peer groups, and competition. The fifth day includes additional activities, culminating in camper-led presentations to describe a planned mission based on a given geologic setting. Presentations include hypotheses, operational requirements and expected data products. SSROV Camp was initiated last summer for three sessions, two in Monterey, CA and one in Oxford, MS. Campers from both regions grasped key elements of the program, based on written responses to questions before and after the camp. On average, 32% of the pre-test questions were answered correctly compared with 80% of the post-test questions. Additional confirmation of gains in campers' knowledge, skills, and critical thinking on environmental issues and engineering problems were apparent during the "jeopardy" competition, nightly homework

In addition PP4P program introduced students to key principles in physics by a hands-on lab environment and demonstrated the real-world social impact of physics. In summer 2012, high school girls worked on physics experimental project on electronics and in summer 2013 they worked on the mechanics. I would share our experience in this program and the impact on the female high school students. This work was supported by 2012 Public Outreach and Informing the Public Grants from American Physical Society.

  11. Archaeology and Memory. Former WWII Camps in Europe

    Humans regularly cooperate with non-kin, which has been theorized to require reciprocity between repeatedly interacting and trusting individuals. However, the role of repeated interactions has not previously been demonstrated in explaining real-world patterns of hunter-gatherer cooperation. Here we explore cooperation among the Agta, a population of Filipino hunter-gatherers, using data from both actual resource transfers and two experimental games across multiple camps. Patterns of cooperation vary greatly between camps and depend on socio-ecological context. Stable camps (with fewer changes in membership over time) were associated with greater reciprocal sharing, indicating that an increased likelihood of future interactions facilitates reciprocity. This is the first study reporting an association between reciprocal cooperation and hunter-gatherer band stability. Under conditions of low camp stability individuals still acquire resources from others, but do so via demand sharing (taking from others), rather than based on reciprocal considerations. Hunter-gatherer cooperation may either be characterized as reciprocity or demand sharing depending on socio-ecological conditions.

  18. Central Atlantic Magmatic Province (CAMP): The Palisade Sill Connection

    Science.gov (United States)

    Ghatak, A.; Basu, A. R.

    2012-12-01

    The extensively studied 200Ma Central Atlantic Magmatic Province (CAMP) is considered to be the world's largest continental Large Igneous Province (LIP) covering up to 7 X 106 km2. This igneous province has been linked to the ~200Ma Mesozoic opening of the Central Atlantic Ocean. This opening fragmented the CAMP into several segments that occur on four different tectonic plates today. The CAMP related LIP is different from others in that it constitutes almost entirely of dikes and sills with sparse volcanic outflows. The 200 Ma Palisade Sill, exposed along the Hudson River in northeastern North America is an expression of the CAMP magmatism. On the basis of similar ages of eruption, Palisade Sill tholeiites have been correlated to other CAMP exposures in four continents. We provide an isotopic tracer study of the Palisade Sill basalts and relate them to low-Ti (gabbros, 3 chilled margin basalts, and 4 sandstones spanning the entire length and thickness of the Palisade Sill in New York and New Jersey. These geochemical data are essential to understand the relationship between mantle geodynamic processes involved in the generation of the CAMP tholeiites prior to the formation of the of the Atlantic Ocean crust. The Palisade Sill basalts of this study yield the typical composition of low-Ti CAMP tholeiites with small LREE enrichments (LaN/SmN = 1.7 to 2.3), radiogenic Sr and negative ɛNd(I) values (87Sr/87Sr(I) = 0.70668 to 0.71037; ɛNd(I) = -0.64 to -3.8), and Pb-isotopic ratios (e.g. 206Pb/204Pb = 18.11 to 18.69) above the NHRL and subparallel to it. These geochemical data indicate the Palisade Sill basalts were derived from a slightly enriched OIB-like mantle source. Further, these rocks were derived by ~15% melting of a slightly depleted spinel peridotite with up to 20% contamination by the continental lithosphere prior to or during the emplacement of these lavas. Since other low-Ti CAMP lavas have similar geochemistry and eruption ages of the Palisade Sill

    Full Text Available When attempting to discover a manner in which to maintain employment during the summer, many individuals have realized the job of camp counselor. What begins as a seasonal position may transform into a lifelong commitment to both person and place. For years, individuals have come to appreciate and understand the experiences that occur when approaching particular places. Data, for this study, was collected via in-depth interviews from twenty-four camp counselors from three separate, but similar camps. Phenomenological analysis on the qualitative data was performed to explore the staff retention amongst counselors. This study links sense of place as a salient component of employee retention among camp counselors. By developing a strong sense of community amongst staff, camp administrators may be promoting a deeper, more long-term, commitment among the staff and towards the camp.

  1. Novel cAMP signalling paradigms: therapeutic implications for airway disease

    2012-01-01

    Since its discovery over 50 years ago, cAMP has been the archetypal second messenger introducing students to the concept of cell signalling at the simplest level. As explored in this review, however, there are many more facets to cAMP signalling than the path from Gs-coupled receptor to adenylyl cyclase (AC) to cAMP to PKA to biological effect. After a brief description of this canonical cAMP signalling pathway, a snapshot is provided of the novel paradigms of cAMP signalling. As in the airwa...

  2. Inactivation of Multidrug Resistance Proteins Disrupts Both Cellular Extrusion and Intracellular Degradation of cAMP

    In addition to xenobiotics and several other endogenous metabolites, multidrug-resistance proteins (MRPs) extrude the second-messenger cAMP from various cells. Pharmacological and/or genetic inactivation of MRPs has been shown to augment intracellular cAMP signaling, an effect assumed to be a direct consequence of the blockade of cAMP extrusion. Here we provide evidence that the augmented intracellular cAMP levels are not due exclusively to the prevention of cAMP efflux because MRP inactivati...

  3. Multiple Facets of cAMP Signalling and Physiological Impact: cAMP Compartmentalization in the Lung

    2012-11-01

    Full Text Available Therapies involving elevation of the endogenous suppressor cyclic AMP (cAMP are currently used in the treatment of several chronic inflammatory disorders, including chronic obstructive pulmonary disease (COPD. Characteristics of COPD are airway obstruction, airway inflammation and airway remodelling, processes encompassed by increased airway smooth muscle mass, epithelial changes, goblet cell and submucosal gland hyperplasia. In addition to inflammatory cells, airway smooth muscle cells and (myofibroblasts, epithelial cells underpin a variety of key responses in the airways such as inflammatory cytokine release, airway remodelling, mucus hypersecretion and airway barrier function. Cigarette smoke, being next to environmental pollution the main cause of COPD, is believed to cause epithelial hyperpermeability by disrupting the barrier function. Here we will focus on the most recent progress on compartmentalized signalling by cAMP. In addition to G protein-coupled receptors, adenylyl cyclases, cAMP-specific phospho-diesterases (PDEs maintain compartmentalized cAMP signalling. Intriguingly, spatially discrete cAMP-sensing signalling complexes seem also to involve distinct members of the A-kinase anchoring (AKAP superfamily and IQ motif containing GTPase activating protein (IQGAPs. In this review, we will highlight the interaction between cAMP and the epithelial barrier to retain proper lung function and to alleviate COPD symptoms and focus on the possible molecular mechanisms involved in this process. Future studies should include the development of cAMP-sensing multiprotein complex specific disruptors and/or stabilizers to orchestrate cellular functions. Compartmentalized cAMP signalling regulates important cellular processes in the lung and may serve as a therapeutic target.

  4. [Medicine in the concentration camps of the Third Reich].

    Between 1942 and 1944 millions of prisoners were subjected to forced labor in concentration camps throughout the Third Reich, all the while being the victims of a systematic and "scientific" extermination policy. Though the policy was directed mainly against Jews, it was implemented against other "inferior races" as well. The prisoners, stripped of all rights, experienced constant humiliation, uncertain survival and terror. The harsh living condition, characterized by crowding, absent sanitation and poor personal hygiene led to considerable morbidity, mainly due to injuries, infectious diseases and famine, and to high mortality rates. Medical care in the camps was the responsibility of the S.S. Each camp had a chief S.S. physician accompanied by a number of assistants and orderlies. There was also a parallel system of "prisoner-physicians." There was a chief prisoner-physician in every camp, and each block was assigned a "block doctor" who was responsible for sanitation, the removal of corpses, setting up the sick- call and authorizing sick leave. Work teams were accompanied by "mobile doctors" (Streckenpfleger), who dispensed first aid for work injuries. Prisoner-physicians were also charged with disinfecting the blocks and maintaining hygienic conditions in the camp. Every camp had one or more blocks, called "Reviers", that were used for treatment and hospitalization. In the larger camps a number of blocks were designated to function as a sort of hospital (Krankenbau). At times one camp out of a group of camps would be set aside as quarantine, primarily for patients with infectious diseases. Officially, the "Revier" was the responsibility of an S.S. physicians', assisted by a chief prisoner-physician, his assistants and, at times, nurses. But in actuality the Reviers were managed by prisoners (Capos) who did not have medical training but were authorized to make decisions in medical matters such as operations and, on occasion, even performed them. The Reviers

    Streptococcus pyogenes produces molecules that inhibit the function of human immune system, thus allowing the pathogen to grow and spread in tissues. It is known that S. pyogenes CAMP factor increases erythrocytosis induced by Staphylococcus aureus β-hemolysin. However, the effects of CAMP factor for immune cells are unclear. In this study, we investigated the effects of CAMP factor to macrophages. Western blotting analysis demonstrated that all examined strains expressed CAMP factor protein. In the presence of calcium or magnesium ion, CAMP factor was significantly released in the supernatant. In addition, both culture supernatant from S. pyogenes strain SSI-9 and recombinant CAMP factor dose-dependently induced vacuolation in RAW 264.7 cells, but the culture supernatant from Δcfa isogenic mutant strain did not. CAMP factor formed oligomers in RAW 264.7 cells in a time-dependent manner. CAMP factor suppressed cell proliferation via G2 phase cell cycle arrest without inducing cell death. Furthermore, CAMP factor reduced the uptake of S. pyogenes and phagocytic activity indicator by RAW 264.7 cells. These results suggest that CAMP factor works as a macrophage dysfunction factor. Therefore, we conclude that CAMP factor allows S. pyogenes to escape the host immune system, and contribute to the spread of streptococcal infection.

    Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sewagram, India's first rural medical institute, has been implementing its community-based public health teaching with the aim of building a physician workforce for the rural poor. For the past four decades, the MGIMS has organized and run the Re-orientation of Medical Education (ROME) camp for final year medical undergraduates at one of the rural centres of the department of Community Medicine. The objectives of the present study were to learn students' perceptions of the value and effectiveness of various components of the ROME camp and learn the factors they perceive facilitate and inhibit learning. A mixed-method research design of quantitative (survey) and qualitative (force field analysis) methods was used. The study participants were all 61 of the final year medical undergraduates participating in the ROME camp in 2008. The quantitative data was analyzed using SPSS software package and summative content analysis of the qualitative data was undertaken. Students were generally very positive about all aspects of the camp and its component parts. The greatest consensus (88.9%, on a 0 to 100% scale) was for the contribution to student learning of the visit to the Primary health centre and Sub-centre, as offering direct exposure and interaction with the village-level service providers. There was poorer consensus for students' involvement with the field-based clinics, as this was felt by some not to contribute significantly to their understanding of socio-economic and environmental factors related to cases (78.8%) and their ability to diagnose health problems in resource poor settings (76.5%). The major strength of the camp was felt to be its exposure visits and hands-on experiences in surveys and interaction with village-level health care providers. Students reported poor interactions with teachers in some educational sessions, including the field-based clinics and classes on theories of national health

  9. From camp to kitsch: A queer eye on console fandom

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available Offering a queer perspective on video game fandom, this article considers the factors that fostered a subculture of Western devotees of Japanese video games in the 1990s. Focused on readers of the English publication Sega Saturn Magazine, it shows how, for these players, Japanese games became the basis of a collective identity founded on precisely the kinds of perverse over-attachment, projective identification and hermeneutic ingenuity that Eve Kosofsky Sedgwick identifies with camp. Citing this subculture as an example of how fans transform the texts they put to use, the article also addresses its implications for our understanding of fandom today, at a time when the proliferation of quantitative analysis techniques is transforming the production and consumption of games. Such techniques, I argue, threaten to compromise the contingency and ambiguity on which camp thrives, instead fostering the kinds of cynical calculation Sedgwick associates with kitsch.

    A new, accurate and sensitive reversed-phase high-performance liquid chromatography (RP-HPLC) as analytical method for the quantitative determination of 11 antibiotics (drugs) and the main metabolites of five of them present in human urine has been worked out, optimized and validated. The analytes belong to four different groups of antibiotics (sulfonamides, tetracyclines, penicillins and anphenicols). The analyzed compounds were sulfadiazine (SDI) and its N(4)-acetylsulfadiazine (NDI) metabolite, sulfamethazine (SMZ) and its N(4)-acetylsulfamethazine (NMZ), sulfamerazine (SMR) and its N(4)-acetylsulfamerazine (NMR), sulfamethoxazole (SMX), trimetroprim (TMP), amoxicillin (AMX) and its main metabolite amoxicilloic acid (AMA), ampicillin (AMP) and its main metabolite ampicilloic acid (APA), chloramphenicol (CLF), thiamphenicol (TIF), oxytetracycline (OXT) and chlortetracycline (CLT). For HPLC analysis, diode array (DAD) and fluorescence (FLD) detectors were used. The separation of the analyzed compounds was conducted by means of a Phenomenex Gemini C(18) (150mm x 4.6mm I.D., particle size 5microm) analytical column with LiChroCART LiChrospher C(18) (4mm x 4mm, particle size 5microm) guard column. Analyzed drugs were determined within 34min using formic acid 0.1% in water and acetonitrile in gradient elution mode as mobile phase. A linear response was observed for all compounds in the range of concentration studied. Two procedures were optimized for sample preparation: a direct treatment with methanol and acetonitrile and a solid phase extraction procedure using Bond Elut Plexa columns. The method was applied to the determination of the analytes in human urine from volunteers under treatment with different pharmaceutical formulations. This method can be successfully applied to routine determination of all these drugs in human urine samples.

    Introduction New paediatric cardiology trainees are required to rapidly assimilate knowledge and gain clinical skills to which they have limited or no exposure during residency. The Pediatric Cardiology Fellowship Boot Camp (PCBC) at Boston Children's Hospital was designed to provide incoming fellows with an intensive exposure to congenital cardiac pathology and a broad overview of major areas of paediatric cardiology practice. The PCBC curriculum was designed by core faculty in cardiac pathology, echocardiography, electrophysiology, interventional cardiology, exercise physiology, and cardiac intensive care. Individual faculty contributed learning objectives, which were refined by fellowship directors and used to build a programme of didactics, hands-on/simulation-based activities, and self-guided learning opportunities. A total of 16 incoming fellows participated in the 4-week boot camp, with no concurrent clinical responsibilities, over 2 years. On the basis of pre- and post-PCBC surveys, 80% of trainees strongly agreed that they felt more prepared for clinical responsibilities, and a similar percentage felt that PCBC should be offered to future incoming fellows. Fellows showed significant increase in their confidence in all specific knowledge and skills related to the learning objectives. Fellows rated hands-on learning experiences and simulation-based exercises most highly. We describe a novel 4-week-long boot camp designed to expose incoming paediatric cardiology fellows to the broad spectrum of knowledge and skills required for the practice of paediatric cardiology. The experience increased trainee confidence and sense of preparedness to begin fellowship-related responsibilities. Given that highly interactive activities were rated most highly, boot camps in paediatric cardiology should strongly emphasise these elements.

    The neurosurgical boot camp has been fully incorporated into U.S. postgraduate education. This is the first implementation of the neurosurgical boot in a developing country. To advance neurosurgical education, we developed a similar boot camp program, in collaboration with Bolivian neurosurgeons, to determine its feasibility and effectiveness in an international setting. In a collective effort, the Bolivian Society for Neurosurgery, Foundation for International Education in Neurological Surgery, Solidarity Bridge, and University of Massachusetts organized and executed the first South American neurosurgical boot camp in Bolivia in 2015. Both U.S. and Bolivian faculty led didactic lectures followed by a practicum day using mannequins and simulators. South American residents and faculty were surveyed after the course to determine levels of enthusiasm and their perceived improvement in fund of knowledge and course effectiveness. Twenty-four neurosurgery residents from 5 South American countries participated. Average survey scores ranged between 4.2 and 4.9 out of 5. Five Bolivian neurosurgeons completed the survey with average scores of 4.5-5. This event allowed for Bolivian leaders in the field to unify around education, resulting in the formation of an institute to continue similar initiatives. Total cost was estimated at $40 000 USD; however, significant faculty, industry, and donor support helped offset this amount. The first South American neurosurgical boot camp had significant value and was well received in Bolivia. This humanitarian model provides a sustainable solution to education needs and should be expanded to other regions as a means for standardizing the core competencies in neurosurgery.

    Full Text Available Abstract Although chickenpox is a generally mild, self-limited illness of children, it can cause fatal disease in adults. Accumulating reports from tropical countries showed a high prevalence of seronegativity among the adults, implying that varicella diseases could become a heavy burden in tropical countries. However, in the situation of humanitarian emergencies in tropical areas, chickenpox has largely been ignored as a serious communicable disease, due to lack of data regarding varicella mortality and hospital admissions in such a context. This is the first report describing an outbreak of chickenpox in a refugee camp of tropical region. In 2008, we experienced a varicella outbreak in ethnic Lao Hmong refugee camp in Phetchabun Province, northern Thailand. The attack rate was 4.0% (309/7,815 and this caused 3 hospitalizations including one who developed severe varicella pneumonia with respiratory failure. All hospitalizations were exclusively seen in adults, and the proportion of patients ≥15 years old was 13.6% (42/309. Because less exposure to varicella-zoster virus due to low population density has previously been suggested to be one of the reasons behind higher prevalence of susceptible adults in tropics, the influx of displaced people from rural areas to a densely populated asylum might result in many severe adult cases once a varicella outbreak occurs. Control interventions such as vaccination should be considered even in refugee camp, if the confluence of the risk factors present in this situation.

    2015-10-01

    Full Text Available While many studies about the 4-H camping experience focus on youth who are campers, few studies examine the outcomes of the experience for counselors. This study examines the extent to which 4-H camp results in transformative learning for 4-H members who serve as camp counselors, examines the perceived changes that occur within counselors, and describes the factors and characteristics of camp that result in personal transformation. The population for this study was 2012 Minnesota 4-H camp counselors. Using the Transformative Learning and the Camp Experience Staff Member Survey, the results indicated that camp counselors experienced transformative learning. Major personal changes involved developing skills for working with children and exposure to new people, activities, and experiences. Factors leading to personal transformation included the opportunity to be role models and positively impact children, opportunities for leadership and challenge, and camp traditions. This study provides support for strong and intentional camp counseling experiences that can positively impact the individual, 4-H campers, and later, the communities in which these camp counselors reside.

    Subcellular compartmentation of the ubiquitous second messenger cAMP has been widely proposed as a mechanism to explain unique receptor-dependent functional responses. How exactly compartmentation is achieved, however, has remained a mystery for more than 40 years. In this study, we developed computational and mathematical models to represent a subcellular sarcomeric space in a cardiac myocyte with varying detail. We then used these models to predict the contributions of various mechanisms that establish subcellular cAMP microdomains. We used the models to test the hypothesis that phosphodiesterases act as functional barriers to diffusion, creating discrete cAMP signaling domains. We also used the models to predict the effect of a range of experimentally measured diffusion rates on cAMP compartmentation. Finally, we modeled the anatomical structures in a cardiac myocyte diad, to predict the effects of anatomical diffusion barriers on cAMP compartmentation. When we incorporated experimentally informed model parameters to reconstruct an in silico subcellular sarcomeric space with spatially distinct cAMP production sites linked to caveloar domains, the models predict that under realistic conditions phosphodiesterases alone were insufficient to generate significant cAMP gradients. This prediction persisted even when combined with slow cAMP diffusion. When we additionally considered the effects of anatomic barriers to diffusion that are expected in the cardiac myocyte dyadic space, cAMP compartmentation did occur, but only when diffusion was slow. Our model simulations suggest that additional mechanisms likely contribute to cAMP gradients occurring in submicroscopic domains. The difference between the physiological and pathological effects resulting from the production of cAMP may be a function of appropriate compartmentation of cAMP signaling. Therefore, understanding the contribution of factors that are responsible for coordinating the spatial and temporal

    Cyclic AMP (cAMP) plays a key regulatory role in most types of cells; however, the pathways controlled by cAMP may present important differences between organisms and between tissues within a specific organism. Changes in cAMP levels are caused by multiple triggers, most affecting adenylyl cyclases, the enzymes that synthesize cAMP. Adenylyl cyclases form a large and diverse family including soluble forms and others with one or more transmembrane domains. Regulatory mechanisms for the soluble adenylyl cyclases involve either interaction with diverse proteins, as happens in Escherichia coli or yeasts, or with calcium or bicarbonate ions, as occurs in mammalian cells. The transmembrane cyclases can be regulated by a variety of proteins, among which the α subunit and the βγ complex from G proteins coupled to membrane receptors are prominent. cAMP levels also are controlled by the activity of phosphodiesterases, enzymes that hydrolyze cAMP. Phosphodiesterases can be regulated by cAMP, cGMP or calcium-calmodulin or by phosphorylation by different protein kinases. Regulation through cAMP depends on its binding to diverse proteins, its proximal targets, this in turn causing changes in a variety of distal targets. Specifically, binding of cAMP to regulatory subunits of cAMP-dependent protein kinases (PKAs) affects the activity of substrates of PKA, binding to exchange proteins directly activated by cAMP (Epac) regulates small GTPases, binding to transcription factors such as the cAMP receptor protein (CRP) or the virulence factor regulator (Vfr) modifies the rate of transcription of certain genes, while cAMP binding to ion channels modulates their activity directly. Further studies on cAMP signalling will have important implications, not only for advancing fundamental knowledge but also for identifying targets for the development of new therapeutic agents.

    Cyclic AMP (cAMP) is a ubiquitous second messenger known to differentially regulate many cellular functions over a wide range of timescales. Several lines of evidence have suggested that the distribution of cAMP within cells is not uniform, and that cAMP compartmentalization is largely responsible for signaling specificity within the cAMP signaling pathway. However, to date, no studies have experimentally measured three dimensional (3D) cAMP distributions within cells. Here we use both 2D and 3D hyperspectral microscopy to visualize cAMP gradients in endothelial cells from the pulmonary microvasculature (PMVECs). cAMP levels were measured using a FRETbased cAMP sensor comprised of a cAMP binding domain from EPAC sandwiched between FRET donors and acceptors -- Turquoise and Venus fluorescent proteins. Data were acquired using either a Nikon A1R spectral confocal microscope or custom spectral microscopy system. Analysis of hyperspectral image stacks from a single confocal slice or from summed images of all slices (2D analysis) indicated little or no cAMP gradients were formed within PMVECs under basal conditions or following agonist treatment. However, analysis of hyperspectral image stacks from 3D cellular geometries (z stacks) demonstrate marked cAMP gradients from the apical to basolateral membrane of PMVECs. These results strongly suggest that 2D imaging studies of cAMP compartmentalization -- whether epifluorescence or confocal microscopy -- may lead to erroneous conclusions about the existence of cAMP gradients, and that 3D studies are required to assess mechanisms of signaling specificity.

    Full Text Available Abstract Background The green alga Chlorella contains high levels of proteins, vitamins, and minerals. We previously reported that a chlorella-derived multicomponent supplement increased the secretion rate of salivary secretory immunoglobulin A (SIgA in humans. Here, we investigated whether intake of this chlorella-derived supplement attenuated the reduced salivary SIgA secretion rate during a kendo training camp. Methods Ten female kendo athletes participated in inter-university 6-day spring and 4-day summer camps. They were randomized into two groups; one took placebo tablets during the spring camp and chlorella tablets during the summer camp, while the other took chlorella tablets during the spring camp and placebo tablets during the summer camp. Subjects took these tablets starting 4 weeks before the camp until post-camp saliva sampling. Salivary SIgA concentrations were measured by ELISA. Results All subjects participated in nearly all training programs, and body-mass changes and subjective physical well-being scores during the camps were comparable between the groups. However, salivary SIgA secretion rate changes were different between these groups. Salivary SIgA secretion rates decreased during the camp in the placebo group (before vs. second, middle, and final day of camp, and after the camp: 146 ± 89 vs. 87 ± 56, 70 ± 45, 94 ± 58, and 116 ± 71 μg/min, whereas no such decreases were observed in the chlorella group (121 ± 53 vs. 113 ± 68, 98 ± 69,115 ± 80, and 128 ± 59 μg/min. Conclusion Our results suggest that a use of a chlorella-derived dietary supplement attenuates reduced salivary SIgA secretion during a training camp for a competitive sport.

    2011-05-01

    Full Text Available This article analyzes gender exploitation in Mexican and Central American migrant farm worker camps in the U.S through small group interactions. We describe how gender exploitation and oppression is transmitted through the social fabric of the camp. We argue that the camp produces an endogenous system of social interaction, which maintains uneven gender relationships. Our data is based on observations of twenty-five women and girls in three labor camps in North Carolina. Research was conducted over a period of six weeks. We found that women who served as the primary bearers of patrimonial authority best maintained the camp community. We conclude that women who successfully reproduce the authority structure gain social status in the camps and are more likely to stay.

    Many children with disabling conditions do not acquire the skills to successfully ride a 2-wheeled bicycle. The aim was to describe cycling patterns before and after an innovative learn-to-ride bike camp and factors that facilitate or hinder the generalization of skills developed at camp to home. Parents and children participated in semistructured interviews 3-4 mo postcamp. Transcripts were examined deductively for participation and contextual influences using a template of codes approach. None of the children were successfully riding a 2-wheeled bicycle before camp. Two patterns of participation were evident from narrative descriptions of postcamp riding: "riders" and "not there yet." Major facilitating factors were the camp itself, the interaction between the camp and the health service, and continued parent involvement. The program transferred well to home for children who were riding independently on the last day of camp. Ongoing support is needed for children "not there yet."

    Full Text Available In this study, a nature camp which provides authentic learning opportunities for children was conducted. Twenty-four 4th and 5th graders (9 girls, 15 boys participated to the camp. The camp program started with observations in the forest nearby. More focused observations were also made. Children discussed their observations with their friends and scientists. A questionnaire was applied at the beginning and end of the camp. The results showed that the nature camp program was effective in extending the children’s conception of the nature by including both living and non-living things. Most of them started the camp with a conception of the nature which consisted of only living things whereas only four children left with this conception at the end. Biological aspects of the nature also increased. Children generally stated that living or non-living things exist or live together at the nature, but relationships between them were noticed by fewer children.

    Alduraidi, Hamza; Waters, Catherine M

    Jordan hosts more Palestinian refugees than any country in the world. Conditions under which people in a community live influence their health-related quality of life (HRQOL). The purpose of this descriptive comparative cross-sectional study was to compare HRQOL of Palestinian refugees in Jordan who live inside camps with those who live outside camps. Participants, recruited from inside the Baqa'a camp (n = 86) and the surrounding Abu Nsair community (n = 91), completed the World Health Organization Quality of Life Brief questionnaire. There were disparities in education and social relations and environment HRQOL related to income and residency, but not gender, among refugees. Refugees living inside camps, particularly if poorer, fared worse than refugees living outside camps. Enhanced programs and policies may be needed to improve HRQOL, education, and socioeconomics for camp refugees. Nursing's perspective on refugee health could make an important contribution to humanitarian efforts and health diplomacy. Copyright © 2017 Elsevier Inc. All rights reserved.

  4. The effectiveness of an American science camp for Taiwanese high school students

    Kuo, Pi-Chu

    The purposes of this study were: (1) to evaluate the effectiveness of an American science camp for Taiwanese high school students in terms of student attitudes toward science; (2) to understand the factors that affect student attitudes toward science in the American science camp. Qualitative and quantitative data were collected and analyzed to answer my research questions: (1) How did the influence of the abroad science camp differ from the local one in terms of student attitudes toward science? (2) How did gender, grade level, and personality affect student attitudes toward science in the abroad science camp? An Attitudes toward Science Inventory was used in this study to measure student attitudes. The results of factor analysis suggested that the attitudes measured in this study include five common factors: science as school subjects (SC), science in society (SS), value of science (VS), science in laboratory (SL), and nature of science (NS). Significant improvements were found in SS, VS, and NS after the experiences of the abroad science camp. In the local science camp, only NS was non-significant comparing before and after the camp. The results from the comparisons between the two science camps show that different program designs have different impacts on student attitudes toward science. Furthermore, whether the science camps are designed based on learning theory or not, and regardless of how much time the campers spend in science-related activities during science camps, science camps can motivate students' interests in learning science. The results of mixed-design ANOVA for gender, grade level, and personality suggest that most of these personal factors did not significantly affect student attitudes. However, extraversion/introversion and sensing/intuition had impacts on the persuasibility of the abroad science camp.

    A Green’s function method is developed to approach the spatiotemporal equations describing the cAMP production in Dictyostelium discoideum, markedly reducing numerical calculations times: cAMP concentrations and gradients are calculated just at the amoeba locations. A single set of parameters is capable of reproducing the different observed behaviors, from cAMP synchronization, spiral waves and reaction-diffusion patterns to streaming and mound formation. After aggregation, the emergence of a circular motion of amoebas, breaking the radial cAMP field symmetry, is observed.

  10. "cAMP sponge": a buffer for cyclic adenosine 3', 5'-monophosphate.

    Directory of Open Access Journals (Sweden)

    Konstantinos Lefkimmiatis

    Full Text Available BACKGROUND: While intracellular buffers are widely used to study calcium signaling, no such tool exists for the other major second messenger, cyclic AMP (cAMP. METHODS/PRINCIPAL FINDINGS: Here we describe a genetically encoded buffer for cAMP based on the high-affinity cAMP-binding carboxy-terminus of the regulatory subunit RIbeta of protein kinase A (PKA. Addition of targeting sequences permitted localization of this fragment to the extra-nuclear compartment, while tagging with mCherry allowed quantification of its expression at the single cell level. This construct (named "cAMP sponge" was shown to selectively bind cAMP in vitro. Its expression significantly suppressed agonist-induced cAMP signals and the downstream activation of PKA within the cytosol as measured by FRET-based sensors in single living cells. Point mutations in the cAMP-binding domains of the construct rendered the chimera unable to bind cAMP in vitro or in situ. Cyclic AMP sponge was fruitfully applied to examine feedback regulation of gap junction-mediated transfer of cAMP in epithelial cell couplets. CONCLUSIONS: This newest member of the cAMP toolbox has the potential to reveal unique biological functions of cAMP, including insight into the functional significance of compartmentalized signaling events.

    In otolaryngology, surgical emergencies can occur at any time. An annual surgical training camp (or 'boot camp') offers junior residents from across North America the opportunity to learn and practice these skills in a safe environment. The goals of this study were to describe the set-up and execution of a simulation-based otolaryngology boot camp and to determine participants' confidence in performing routine and emergency on-call procedures in stressful situations before and after the boot camp. There were three main components of the boot camp: task trainers, simulations and an interactive panel discussion. Surveys were given to participants before and after the boot camp, and their confidence in performing the different tasks was assessed via multiple t-tests. Participants comprised 22 residents from 12 different universities; 10 of these completed both boot camp surveys. Of the nine tasks, the residents reported a significant improvement in confidence levels for six, including surgical airway and orbital haematoma management. An otolaryngology boot camp gives residents the chance to learn and practice emergency skills before encountering the emergencies in everyday practice. Their confidence in multiple skillsets was significantly improved after the boot camp. Given the shift towards competency-based learning in medical training, this study has implications for all surgical and procedural specialties.

    1919-05-01

    1. 13,460 men, or about 80 per cent of the entire camp strength, were vaccinated against pneumonia with pneumococcus lipovaccine. 2. The dosage employed in all cases was 1 cc. of the lipovaccine containing approximately 10 billion each of Pneumococcus Types I, II, and III. 3. Both the local and general reactions produced by the vaccine were usually mild. Only 0.7 per cent of those who received the vaccine were sufficiently affected to need hospital care. None of these was seriously ill, and a majority of them returned to duty on the 2nd or 3rd day after admission. 4. Most of the troops inoculated were under observation for 2 or 3 months after vaccination. During this period there were 32 cases of Pneumococcus Type I, II, and III pneumonia among the vaccinated four-fifths of camp, and 42 cases of pneumonia of these types among the unvaccinated one-fifth of camp. If, however, all cases of pneumonia that developed within 1 week after vaccination are excluded from the vaccinated group, there remain only 8 cases of pneumonia produced by fixed types, and these were all secondary to severe attacks of influenza. This exclusion is justified by the fact that protective bodies do not begin to appear in the serum until the 8th day after injection of pneumococcus lipovaccine. 5. There is no evidence whatever that pneumococcus vaccine predisposes the individual even temporarily toward either pneumococcus or streptococcus pneumonia. 6. The weekly incidence rate for pneumonia (all types) among the vaccinated troops was conspicuously lower than that for the unvaccinated troops. 7. The pneumonia incidence rate per 1,000 men during the period of the experiment was twice as high for unvaccinated recruits as for vaccinated recruits, and nearly seven times as high for unvaccinated seasoned men as for vaccinated seasoned men. 8. Influenza causes a marked reduction in resistance to pneumonia even among vaccinated men. Of the 155 cases of pneumonia (all types) developing 1 week or more

  15. Classification of MEC with the ALLTEM at Camp Stanley, Texas

    Asch, T.; Moulton, C.; Smith, D.V.

    2011-01-01

    The ALLTEM is a multi-axis electromagnetic induction system designed for unexploded ordnance UXO applications. It uses a continuous triangle-wave excitation and provides good late-time signal-to-noise ratio SNR especially for ferrous targets. Multi-axis transmitter Tx and receiver Rx systems such as ALLTEM provide a richer data set from which to invert for the target parameters required to distinguish between clutter and UXO. Inversions of field data acquired between 2006 and 2010 over the Army's UXO Standardized Test sites at the Yuma Proving Ground YPG in Arizona and at the Aberdeen Proving Ground APG in Maryland have produced reasonable and generally repeatable results for many UXO items buried at different orientations and depths. In February-March 2011 ALLTEM data was acquired at two locations on the Camp Stanley Storage Activity CSSA just north of San Antonio, Texas. Camp Stanley is used to store munitions as well as test, fire, and overhaul munitions components. Site B-20 is an open burn/open detonation OBOD area and Site B-27 consists of narrow trenches blasted into limestone containing buried range and munitions debris and possibly MEC. The processing, analysis, and classification techniques developed at the controlled environments of YPG and APG have been applied to these two "live" sites at Camp Stanley. ALLTEM data analysis includes both classical numerical inversion of data from each anomaly and clustering of the raw data by means of a self-organizing map SOM via generalized neural network algorithms. Final classification consists of an integration of both the numerical and SOM results. ?? 2011 Society of Exploration Geophysicists.

    Turkana is the largest district in Kenya, situated in the Northwest of the country. It features a semi-nomadic population of 850,000. Around 60% of population lives below the poverty threshold. The ratio of doctors is 1:75,000 inhabitants. Five ophthalmologists took part in the last deployment in November. Local staff had previously selected the patients from the rural areas, as well as in Lodwar, the capital of the district. Of the 371 patients who attended the clinic, 128 required surgery. To describe the pediatric population attended to in the last «Turkana Eye Project» Camp. Description of the ophthalmic pathologies of the children seen in the clinic in this surgical camp, and the diagnostic and therapeutic options according to the limitations of the environment. Of the 371 patients, 54 were younger than 15 years old (14.5%). Four children had surgery (3.25% of the 128 patients). In 2 more cases surgery was the indicated but not performed. Therefore, of the total of 54 cases, 6 could be considered as surgical (11.1%), and 17 suffered ophthalmic problems other than refraction defects, or mild ocular surface pathologies: traumatic cataracts, neuropathies, impetigo, exophthalmos, retinal dystrophies, dermoid cysts, or nyctalopia. The etiology was traumatic in four of the 17 children (23.5%). Surgical camps are increasing in the developing countries. They are usually focused on particular pathologies, such as cataracts or trachoma. Our case series shows the importance of pediatric teams and the need to be prepared to face complex pediatric pathologies. Copyright © 2012 Sociedad Española de Oftalmología.

  19. Genetically-encoded tools for cAMP probing and modulation in living systems.

    Directory of Open Access Journals (Sweden)

    Valeriy M Paramonov

    2015-09-01

    Full Text Available Intracellular 3'-5'-cyclic adenosine monophosphate (cAMP is one of the principal second messengers downstream of a manifold of signal transduction pathways, including the ones triggered by G protein-coupled receptors. Not surprisingly, biochemical assays for cAMP have been instrumental for basic research and drug discovery for decades, providing insights into cellular physiology and guiding pharmaceutical industry. However, despite impressive track record, the majority of conventional biochemical tools for cAMP probing share the same fundamental shortcoming - all the measurements require sample disruption for cAMP liberation. This common bottleneck, together with inherently low spatial resolution of measurements (as cAMP is typically analyzed in lysates of thousands of cells, underpin the ensuing limitations of the conventional cAMP assays: 1 genuine kinetic measurements of cAMP levels over time in a single given sample are unfeasible; 2 inability to obtain precise information on cAMP spatial distribution and transfer at subcellular levels, let alone the attempts to pinpoint dynamic interactions of cAMP and its effectors. At the same time, tremendous progress in synthetic biology over the recent years culminated in drastic refinement of our toolbox, allowing us not only to bypass the limitations of conventional assays, but to put intracellular cAMP life-span under tight control – something, that seemed scarcely attainable before. In this review article we discuss the main classes of modern genetically-encoded tools tailored for cAMP probing and modulation in living systems. We examine the capabilities and weaknesses of these different tools in the context of their operational characteristics and applicability to various experimental set-ups involving living cells, providing the guidance for rational selection of the best tools for particular needs.

  20. Rapid Assessment of Seismic Vulnerability in Palestinian Refugee Camps

    Al-Dabbeek, Jalal N.; El-Kelani, Radwan J.

    Studies of historical and recorded earthquakes in Palestine demonstrate that damaging earthquakes are occurring frequently along the Dead Sea Transform: Earthquake of 11 July 1927 (ML 6.2), Earthquake of 11 February 2004 (ML 5.2). In order to reduce seismic vulnerability of buildings, losses in lives, properties and infrastructures, an attempt was made to estimate the percentage of damage degrees and losses at selected refugee camps: Al Ama`ri, Balata and Dhaishe. Assessing the vulnerability classes of building structures was carried out according to the European Macro-Seismic Scale 1998 (EMS-98) and the Fedral Emergency Management Agency (FEMA). The rapid assessment results showed that very heavy structural and non structural damages will occur in the common buildings of the investigated Refugee Camps (many buildings will suffer from damages grades 4 and 5). Bad quality of buildings in terms of design and construction, lack of uniformity, absence of spaces between the building and the limited width of roads will definitely increase the seismic vulnerability under the influence of moderate-strong (M 6-7) earthquakes in the future.

  1. Purification of the surface cAMP receptor in Dictyostelium

    Energy Technology Data Exchange (ETDEWEB)

    1987-01-05

    We have previously identified and demonstrated reversible ligand-induced modification of the major cell surface cAMP receptor in Dictyostelium discoideum. The receptor, or a subunit of it, has been purified to homogeneity by hydroxylapatite chromatography followed by two-dimensional preparative sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The purification was monitored by following /sup 32/Pi incorporated by photoaffinity labeling with 8-azido-(/sup 32/P)cAMP or by in vivo labeling with /sup 32/Pi. Two interconvertible forms of the receptor, designated R (Mr 40,000) and D (Mr 43,000), co-purified. Two-dimensional peptide maps of independently purified and /sup 125/I-iodinated R and D forms of the receptor were nearly identical but did have several distinct peptides. The estimated 6000-fold purification required is consistent with the number of cell surface binding sites assuming there are not multiple binding sites/polypeptide. In the accompanying article we report the generation of a monospecific polyclonal antiserum which has helped to further elucidate the physical properties and developmental regulation of the cAMP receptor.

    Full Text Available This study presents a case study on the utilization of global solar radiation data on horizontal surface to perform economical feasibility of using Photovoltaic (PV panels with battery backup to meet a small load for a camping site in Saudi Arabia. The analysis considers three scenarios with daily average energy demands of: (i full load, (ii 75% load and (iii half load with annual peak load of 3.84, 3.06 and 2.27 kW, respectively. Each of these loads is further studied economically to investigate the effect of battery storage for 1 to 5 days. The study also compares the cost of electricity generation in $/kWh from PV system and diesel generating systems. The lower mean temperature (~20°C and high intensity of radiation (~ 6.3 kWh m2/day in Abha make it a promising site for the usage of PV systems for desert camping. Analysis of the data indicates that the battery storage capacity cost plays an important role in the overall cost of the PV system. The economical indicators suggest that larger PV systems be preferred over the smaller ones with minimal storage option. The energy generation cost analysis indicated that the diesel generating cost was found to be 29, 56 and 116% higher than the PV system for full, 75% and half load systems, respectively.

    To evaluate the efficacy of a mammography boot camp (MBC) to improve radiologists' performance in interpreting mammograms in the National Cancer Screening Program (NCSP) in Korea. Between January and July of 2013, 141 radiologists were invited to a 3-day educational program composed of lectures and group practice readings using 250 digital mammography cases. The radiologists' performance in interpreting mammograms were evaluated using a pre- and post-camp test set of 25 cases validated prior to the camp by experienced breast radiologists. Factors affecting the radiologists' performance, including age, type of attending institution, and type of test set cases, were analyzed. The average scores of the pre- and post-camp tests were 56.0 ± 12.2 and 78.3 ± 9.2, respectively (p < 0.001). The post-camp test scores were higher than the pre-camp test scores for all age groups and all types of attending institutions (p < 0.001). The rate of incorrect answers in the post-camp test decreased compared to the pre-camp test for all suspicious cases, but not for negative cases (p > 0.05). The MBC improves radiologists' performance in interpreting mammograms irrespective of age and type of attending institution. Improved interpretation is observed for suspicious cases, but not for negative cases.

  15. Global and local missions of cAMP signaling in neural plasticity, learning and memory

    Directory of Open Access Journals (Sweden)

    Daewoo eLee

    2015-08-01

    Full Text Available The fruit fly Drosophila melanogaster has been a popular model to study cAMP signaling and resultant behaviors due to its powerful genetic approaches. All molecular components (AC, PDE, PKA, CREB, etc essential for cAMP signaling have been identified in the fly. Among them, adenylyl cyclase (AC gene rutabaga and phosphodiesterase (PDE gene dunce have been intensively studied to understand the role of cAMP signaling. Interestingly, these two mutant genes were originally identified on the basis of associative learning deficits. This commentary summarizes findings on the role of cAMP in Drosophila neuronal excitability, synaptic plasticity and memory. It mainly focuses on two distinct mechanisms (global versus local regulating excitatory and inhibitory synaptic plasticity related to cAMP homeostasis. This dual regulatory role of cAMP is to increase the strength of excitatory neural circuits on one hand, but to act locally on postsynaptic GABA receptors to decrease inhibitory synaptic plasticity on the other. Thus the action of cAMP could result in a global increase in the neural circuit excitability and memory. Implications of this cAMP signaling related to drug discovery for neural diseases are also described.

  1. Targeting brain tumor cAMP: the case for sex-specific therapeutics

    Directory of Open Access Journals (Sweden)

    Nicole M Warrington

    2015-07-01

    Full Text Available A relationship between cyclic adenosine 3’, 5’-monophosphate (cAMP levels and brain tumor biology has been evident for nearly as long as cAMP and its synthetase, adenylate cyclase (ADCY have been known. The importance of the pathway in brain tumorigenesis has been demonstrated in vitro and in multiple animal models. Recently, we provided human validation for a cooperating oncogenic role for cAMP in brain tumorigenesis when we found that SNPs in ADCY8 were correlated with glioma (brain tumor risk in individuals with Neurofibromatosis type 1 (NF1. Together, these studies provide a strong rationale for targeting cAMP in brain tumor therapy. However, the cAMP pathway is well known to be sexually dimorphic, and SNPs in ADCY8 affected glioma risk in a sex-specific fashion, elevating the risk for females while protecting males. The cAMP pathway can be targeted at multiple levels in the regulation of its synthesis and degradation. Sex differences in response to drugs that target cAMP regulators indicate that successful targeting of the cAMP pathway for brain tumor patients is likely to require matching specific mechanisms of drug action with patient sex.

    2016-04-01

    Constant stress, slave labor, tortures, and starvation all affected the health of concentration camp prisoners, contributing to multimorbidities, increased mortality and accelerated development of chronic illnesses, what we have shown in an earlier publication. The interrelated somatic and psychological symptoms gave rise to concentration camp syndrome (KZ-syndrome), which has many features of PTSD, occurring frequently nowadays. The paper attempts at assessing the influence of concentration camp conditions on functional disorders in each system of the human body, occurring in KZ-syndrome, and at demonstrating the progressive nature of the syndrome. A retrospective assessment of the former prisoners' health after 5 and 30 years following their leaving camps was performed based on medical records and surveys. The materials included 250 former prisoners who underwent medical examination in 1950, i.e. 5 years after leaving the camp, of whom 120 former prisoners survived and were examined and surveyed in 1975, i.e. 30 years after leaving the camp. KZ-syndrome was shown to occur in 58.8% of former prisoners 5 years after leaving the camp, and in 77.5% after 30 years (p < 0.001), which confirms the syndrome's chronic and progressive nature. Pathological sequels of internment in concentration camps, in the form of KZ-syndrome, were observed in most former prisoners. Over time, the number of morbidities and the intensity of symptoms increased, which indicates that the syndrome has a chronic and progressive nature. KZ-syndrome is a multi-organ disorder, with numerous chronic comorbidities exacerbating the progression.

  17. cAMP Signals in Drosophila Motor Neurons Are Confined to Single Synaptic Boutons

    2016-10-01

    Full Text Available The second messenger cyclic AMP (cAMP plays an important role in synaptic plasticity. Although there is evidence for local control of synaptic transmission and plasticity, it is less clear whether a similar spatial confinement of cAMP signaling exists. Here, we suggest a possible biophysical basis for the site-specific regulation of synaptic plasticity by cAMP, a highly diffusible small molecule that transforms the physiology of synapses in a local and specific manner. By exploiting the octopaminergic system of Drosophila, which mediates structural synaptic plasticity via a cAMP-dependent pathway, we demonstrate the existence of local cAMP signaling compartments of micrometer dimensions within single motor neurons. In addition, we provide evidence that heterogeneous octopamine receptor localization, coupled with local differences in phosphodiesterase activity, underlies the observed differences in cAMP signaling in the axon, cell body, and boutons.

    Davidov, Jonathan; Eisikovits, Zvi

    2015-07-01

    Nazi death camps, as any total institutions, were designed to deny any free will or choice from inmates. Furthermore, former inmates in such extreme conditions often account for their own actions and behavior in such settings as inevitable ("I had no other choice"). This study examines the questions of free will vs. determinism in death camps from a descriptive-phenomenological perspective. Data was collected through in-depth interviews with 20 former death camp inmates. The following themes emerged from the qualitative analysis of the data: the 'selection' experience; 'borrowed time' perception; and the experience of 'nothingness'. A conceptual model grounded in these data was developed to illustrate the inmate's lived experience of choice in the reality of the camps. Analysis of the model indicates that under the extreme conditions of the death camp, free will and existence are interchangeable: "I choose - therefore I am".

    In the present study, we evaluate the impact of participation in a mental health recovery camp on the clinical confidence of undergraduate nursing students in dealing with individuals with mental illness. Twenty undergraduate nursing students who participated in the recovery camp completed the Mental Health Nursing Clinical Confidence Scale both before and directly after attending the camp. Data were analysed using descriptive and inferential statistics. Participation in the recovery camp was associated with a statistically-significant increase in students' level of overall confidence between the pretest and post-test data (P students over the age of 25 years and who do not have a family history of mental illness are more likely to self-report a higher level of confidence in both the pre- and post-results. The clinical confidence of undergraduate nursing students improved through participation in an immersive clinical experience within the recovery camp.

    Do you remember childhood dreams of being an astronomer, or the ravenous desire for ever larger glass and better equipment as an amateur astronomer? What if your child or the person down the street could live that dream for a weekend or a week? The University of Arizona Astronomy Camp continues to substantiate those dreams after more than two decades in existence. Astronomy Camp is an immersion hands-on field experience in astronomy, ranging from two to eight nights, occurring a few times per year. Participants span an age range from elementary students to octogenarians. The three basic offerings include adult camps, a beginning Camp for teenagers, and an advanced teen Camp. Several variants of the basic Camp model have evolved, including an ongoing decade long series of specialized Camps for Girl Scout leaders from across the country, funded by the NIRCam instrument development program for the James Webb Space Telescope. The advanced teen Camp is a microcosm of the entire research arc: the participants propose projects, spend the week collecting and analyzing data using research grade CCDs, infrared arrays, and radio/sub-millimeter telescopes, and finish with a presentation of the results. This past summer the Camps moved to Kitt Peak National Observatory for the first time, providing access to a vast and diverse collection of research instruments, including the 0.9-meter WIYN and 2.3-meter Bok telescopes, the McMath-Pierce Solar Telescope, and the 12-meter ARO radio telescope. Education research into the Camp's impact indicates that reasons for its appeal to youth include a learner-centered and personal approach with a fun attitude toward learning, authentic scientific inquiry led by mentors who are real scientists, a peer group with common interests in science and engineering, and the emotional appeal of spending time on a dark "sky island" devoted to the exploration of nature.

    2015-05-01

    Full Text Available This data was collected via low-altitude UAV (Unmanned Aerial Vehicle survey of an area of Clifton Camp (ST565557330, best known for its Iron Age promontory fort. The dataset comprises of metadata records, near-vertical photographs and a derived 3D polygonal mesh. This dataset has been constructed with two kinds of reuse in mind: Firstly, the area surveyed is culturally rich and underexplored; while some of the non-natural features detected by this survey can be identified, others cannot. This data is intended to inform future investigations of the site. Secondly, the survey methodologies employed and the structuring of the resulting dataset are intended to act as an exemplar, a standard method of creating survey data while prioritising open technologies, and of organising UAV survey datasets to ensure maximum re-usability.

    2011-10-01

    The purpose of this paper is to apply a stress model drawn from the literature to the relief and social service workers who have been active in refugee camps for a prolonged period of time. Working in difficult environments, social service workers deliver essential services to refugee populations around the world. A model of four work-stress determinants--tasks, management, appreciation and collaboration--was tested on 274 social workers in five regions of the Middle East (Jordan, Lebanon and Syria, as well as the occupied Palestinian territories of the Gaza Strip and the West Bank). Statistical fit indices were adequate but two relationships were statistically insignificant. The collaboration variable was dropped to create a modified model with tasks indirectly and management and appreciation directly affecting work-related stress. The five direct relationships and two indirect relationships of this modified model are consistent with stress theory, and all relationships--direct and indirect--are statistically significant.

    2014-06-01

    Full Text Available The paper studies the problem of agitation work done among POWs in Soviet camps, the creation of military units and political organizations from POWs. Not only armed force was used during the Second World War, but also the power of words. The battles were accompanied by the information warfare. Opponents tried to use all possible means to manipulate people’s minds. Main directions of agitation and propaganda were defined by the «Soviet bureau of military and political propaganda», as well as the 7th Division of Soviet army. In the propaganda work among German POWs, the priority was given on shaping the ideological and political views of former soldiers and officers of the Wehrmacht. As the result of the analysis of sources the author comes to conclusion that POWs of the Second World War period became the object of testing means and methods of ideological struggle of warring nations.

    The extraction of high resolution surface information from satellite data has become an important area of research. One of the numerous fields of application is disaster management. Detailed information about the affected terrain is not only needed for analyses during the emergency relief phase, but also for reconstruction and prevention activities. In this paper the authors present the generation of a Digital Surface Model (DSM) based on three very high resolution optical satellite images. The DSM was produced to supplement a flood mapping activity in Jordan and serves as example for the implementation of scientific results during an emergency request. The flood affected the Zaatari refugee camp in Jordan and was mapped by the Center for Satellite Based Crisis Information (ZKI) at the German Aerospace Center (DLR) in January 2013 under emergency mapping conditions.

    Specialty-specific 'boot camps' boost the competence and confidence of medical school graduates as they prepare to enter a residency programme. We sought to evaluate the efficacy of a specialty-neutral Internship Preparation Camp (IPC) that we developed and made available to senior medical students at our medical school. The primary goal of the IPC is to educate students in the cognitive and procedural skills that are applicable to postgraduate year 1 trainees in all fields of specialisation. The curriculum was developed through input from senior medical students and faculty from multiple specialties. The course used small-group sessions and skills labs led by distinguished speakers from various professions (medicine, nursing and pharmacy) to teach senior medical students the information and skills common to the needs of all new physicians, regardless of the specialty they have chosen. The course was presented across 3 half-days and was offered just prior to graduation. Of 166 possible participants, 65 attended the course; 39 (60%) of them completed evaluations immediately following the course and 29 (45%) of participants completed a follow-up evaluation 3 months later. All respondents reported increased confidence in caring for patients in all subject areas taught. In the follow-up survey, 82% of respondents reported using information learned during the course on an hourly, daily or weekly basis in their care of patients. A specialty-neutral IPC is of benefit to its attendees, regardless of the medical specialty in which they train. Published by the BMJ Publishing Group Limited.

    The first asthma camp in Turkey was organized for one week in Iznik in September 1996. The camps were continued annually around the same time of the year in 1997, 1998, 2000, and in the consecutive years thereafter. The camp includes educational, sports and social activities. Children's knowledge about asthma and their attitudes towards physical and social activities were evaluated by a questionnaire. Pulmonary function tests were performed on the first and last day of the camp. There was no statistically significant difference between the mean spirometric values of the first and last day of the camp in spite of a vigorous physical and social program. Children enhanced their skills and knowledge about asthma and gained self-confidence in participating in sportive and social activities during the camp program. They did not experience any emergency room visit in the following year. In conclusion, a summer camping experience is very beneficial for asthmatic children in terms of both self-education and social and physical participation.

    2014-09-01

    Advances in medicine have reduced mortality among children with complex medical conditions, resulting in a growing number of young patients living with chronic illnesses. Despite an improved prognosis, these children experience significant psychosocial morbidity, such as depression and anxiety. Therapeutic summer recreation camps have been proposed as an intervention to enhance quality of life among these children. The purpose of this systematic review was to assess the psychosocial impact of camp for children with chronic illnesses. A systematic review of central databases was undertaken using key words, and a rating tool – the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies – was employed to rate methodological quality. 21 studies were included in this systematic review. Although overall methodological quality was weak, camp participation appeared to offer short-term psychosocial benefits on some parameters in children with a variety of chronic illnesses. There was some consistency in improved social outcomes, such as social interaction and acceptance. Based on the available evidence, it is premature to make robust claims regarding the psychosocial impact of camp as a therapeutic intervention. Theoretically informed camp programs, long-term follow-up, and incorporating camp-based messaging into routine hospital care,may enhance the utility of camp as a potential psychosocial intervention in paediatrics.

    M-CSF is a key cytokine in macrophage development by inducing MAPKs activation, and cAMP can inhibit MAPKs activation induced by inflammatory stimuli. To explore the effects of cAMP on M-CSF-induced MAPKs activation and on macrophage development, the model of bone marrow-derived murine macrophages (BMMs) was used. The effects of cAMP on M-CSF-induced MAPKs activation were analyzed by Western blotting assay, and the effects of cAMP on CD14 and F4/80 expression during macrophage development were examined by FACS analysis.Macrophage morphology showed the successful establishment of the model of macrophage development. Western blotting assay revealed that M-CSF activated ERK, JNK and p38 in both mature and immature macrophages, and cAMP inhibited M-CSF-induced ERK, JNK and p38 activation in a time-dependent manner. FACS analysis revealed that macrophage development was impaired with cAMP pretreatment. In conclusion, cAMP modulates macrophage development by suppressing M-CSF-induced MAPKs activation.

  12. Suicide in Inmates in Nazis and Soviet Concentration Camps: Historical Overview and Critique

    López-Muñoz, Francisco; Cuerda-Galindo, Esther

    2016-01-01

    Living conditions in concentration camps were harsh and often inhumane, leading many prisoners to commit suicide. We have reviewed this topic in Nazi concentration camps (KL), Soviet special camps, and gulags, providing some preliminary data for our research. Data show that the incidence of suicide in Nazi KL could be up to 30 times higher than the general population and was also much higher than in Soviet special camps (maybe due to more favorable conditions for prisoners and the abolishment of death penalty), while available data on Soviet gulags are contradictory. However, data interpretation is very controversial, because, for example, the Nazi KL authorities used to cover-up the murder victims as suicides. Most of the suicides were committed in the first years of imprisonment, and the method of suicide most commonly used was hanging, although other methods included cutting blood vessels, poisoning, contact with electrified wire, or starvation. It is possible to differentiate two behaviors when committing suicide; impulsive behavior (contact with electrified barbed wire fences) or premeditated suicide (hanging up or through poison). In Soviet special camps, possible motives for suicides could include feelings of guilt for crimes committed, fear of punishment, and a misguided understanding of honor on the eve of criminal trials. Self-destructive behaviors, such as self-mutilation in gulag camps or prisoners who let themselves die, have been widely reported. Committing suicide in concentration camps was a common practice, although precise data may be impossible to obtain. PMID:27303312

    2016-12-01

    Full Text Available The purpose of this article is to present findings related to parent- and youth-reported outcomes from a nutrition- and fitness-themed summer camp targeting low-income families and to identify lessons learned in the implementation, evaluation and sustainability of a summer program. The Healthy Lifestyle Fitness Camp, offered through UC Cooperative Extension (UCCE, was a summer camp program for low-income youth at high risk for obesity. From 2009 to 2012, UCCE nutrition staff in Fresno County collaborated with the camp staff to provide a 6-week nutrition education program to the campers and their parents. Anthropometry and dietary data were collected from youth. Data about food preferences and availability were collected from youth and parents. As reported by parents in pre- to immediately post-camp surveys, Healthy Lifestyle Fitness campers consumed fruits and vegetables promoted at camp more often, relative to a comparison group of youth in a nearby non-nutrition themed camp. Summer programs may be an effective tool in the reduction of childhood obesity risk factors if implemented appropriately into the community and through the utilization of supportive partnerships such as UCCE and local parks and recreation departments.

    The Saccharomyces cerevisiae strain P-28-24C, from which cAMP requiring mutants derived, responded to exogenously added cAMP. Upon the addition of cAMP, this strain showed phenotypes shared by mutants with elevated activity of the cAMP pathway. Genetic analysis involving serial crosses of this strain to a strain with another genetic background revealed that the responsiveness to cAMP results from naturally occurring loss-of-function alleles of PDE1 and PDE2, which encode low and high affinity...

    Nerve growth factor (NGF)-mediated neurite outgrowth in rat pheochromocytoma PC12 cells has been described to be synergistically potentiated by the simultaneous addition of dibutyryl cAMP. To elucidate further the role of cAMP in NGF-induced neurite outgrowth we have used the adenylate cyclase activator forskolin, cAMP, and a set of chemically modified cAMP analogues, including the adenosine cyclic 3',5'-phosphorothioates (cAMPS) (Rp)-cAMPS and (Sp)-cAMPS.

  17. Role of cAMP in the reactivation of demembranated ram spermatozoa.

    Science.gov (United States)

    San Agustin, J T; Witman, G B

    1994-01-01

    Ejaculated ram sperm were demembranated with Triton X-100, separated from the detergent-soluble matrix, and reactivated [San Agustin and Witman (1993): Cell Motil. Cytoskeleton 24:264-273]. The percent motility of models prepared from freshly washed sperm was comparable to that of the washed sample before demembranation, regardless of whether cAMP was included in the reactivation medium. However, demembranated models derived from aging or metabolically inhibited sperm exhibited a lower percent reactivation and required cAMP to attain the level of motility of freshly washed sperm. Cyclic AMP was approximately 100 times more effective than cGMP. The requirement for cAMP could be bypassed by addition of porcine heart cAMP-dependent protein kinase (PKA) catalytic subunit to the reactivation medium, demonstrating that cAMP was acting via PKA. The cAMP stimulation of reactivation was not affected by inclusion of the PKA inhibitor PKI(5-24) in the reactivation medium, but was decreased when the models were preincubated with PKI(5-24) prior to reactivation. The cytosol-free models retained > 90% of the sperm PKA activity; therefore, the PKA appears to be anchored to internal sperm structures. This PKA could not be extracted by cAMP or Triton X-100 alone, but only by cAMP and Triton X-100 in combination. We conclude that cAMP-dependent protein phosphorylation is critical for sperm motility, but that the essential protein phosphate sites turn over slowly under our reactivation conditions, so that the cAMP requirement is apparent only in models prepared from sperm having a low internal ATP or cAMP content. Interestingly, reactivation was rapidly blocked by the peptide arg-lys-arg-ala-arg-lys-glu, which has been reported to be a selective inhibitor of cGMP-dependent protein kinase.

  18. Temporal cAMP Signaling Selectivity by Natural and Synthetic MC4R Agonists.

    Molden, Brent M; Cooney, Kimberly A; West, Kirk; Van Der Ploeg, Lex H T; Baldini, Giulia

    2015-11-01

    The melanocortin-4 receptor (MC4R) is a G protein-coupled receptor expressed in the brain, where it controls energy balance through pathways including α-melanocyte-stimulating hormone (α-MSH)-dependent signaling. We have reported that the MC4R can exist in an active conformation that signals constitutively by increasing cAMP levels in the absence of receptor desensitization. We asked whether synthetic MC4R agonists differ in their ability to increase intracellular cAMP over time in Neuro2A cells expressing endogenous MC4R and exogenous, epitope-tagged hemagglutinin-MC4R-green fluorescent protein. By analyzing intracellular cAMP in a temporally resolved Förster resonance energy transfer assay, we show that withdrawal of α-MSH leads to a quick reversal of cAMP induction. By contrast, the synthetic agonist melanotan II (MTII) induces a cAMP signal that persists for at least 1 hour after removal of MTII from the medium and cannot be antagonized by agouti related protein. Similarly, in mHypoE-42 immortalized hypothalamic neurons, MTII, but not α-MSH, induced persistent AMP kinase signal, which occurs downstream of increased cAMP. By using a fluorescence recovery after photobleaching assay, it appears that the receptor exposed to MTII continues to signal after being internalized. Similar to MTII, the synthetic MC4R agonists, THIQ and BIM-22511, but not LY2112688, induced prolonged cAMP signaling after agonist withdrawal. However, agonist-exposed MC4R desensitized to the same extent, regardless of the ligand used and regardless of differences in receptor intracellular retention kinetics. In conclusion, α-MSH and LY2112688, when compared with MTII, THIQ, and BIM-22511, vary in the duration of the acute cAMP response, showing distinct temporal signaling selectivity, possibly linked to specific cell compartments from which cAMP signals may originate.

    During the years of 1981 and 1982, 89 former prisoners of the Auschwitz-Birkenau concentration camp responded to questionnaires on mussulmen-prisoners in the extreme phase of starvation disease. In this article, I describe the origin of the term "mussulman," mussulmens' somatic and mental state, their behavior and camp customs. Prisoners characterized as mussulmen remain between life and death, without expressing emotional reactions and defense mechanisms apart from a hypersensibility to food-related stimuli. A mussulman was a product of the camp factory of death. A deep somatic and emotional stigma remains in those who survived the mussulmen state.

  1. Comparison of cAMP with other radioprotectors against chronic damage to the rat parotid gland

    Radiation damage to the parotid gland is protectable by cAMP during the first week after irradiation (acute phase), though appreciable recovery occurred later with or without such protection. Further damage developed later (chronic phase, 60-90 days), and cAMP was still protective against this damage with a dose modification factor of 1.86 for gland weight. A summary of the protective factors, acute and chronic, for WR-2721, isoproterenol, and cAMP is included. Chronic damage is about 1.5 times as great as acute, and protection against acute and chronic damage is about equal for all three compounds.

    Highlights: Black-Right-Pointing-Pointer cAMP blocks cell death induced by TNF and actinomycin D in cultured hepatocytes. Black-Right-Pointing-Pointer cAMP blocks NF-{kappa}B activation induced by TNF and actinomycin D. Black-Right-Pointing-Pointer cAMP blocks DISC formation following TNF and actinomycin D exposure. Black-Right-Pointing-Pointer cAMP blocks TNF signaling at a proximal step. -- Abstract: Tumor necrosis factor {alpha} (TNF) is a pleiotropic proinflammatory cytokine that plays a role in immunity and the control of cell proliferation, cell differentiation, and apoptosis. The pleiotropic nature of TNF is due to the formation of different signaling complexes upon the binding of TNF to its receptor, TNF receptor type 1 (TNFR1). TNF induces apoptosis in various mammalian cells when the cells are co-treated with a transcription inhibitor like actinomycin D (ActD). When TNFR1 is activated, it recruits an adaptor protein, TNF receptor-associated protein with death domain (TRADD), through its cytoplasmic death effector domain (DED). TRADD, in turn, recruits other signaling proteins, including TNF receptor-associated protein 2 (TRAF2) and receptor-associated protein kinase (RIPK) 1, to form a complex. Subsequently, this complex combines with FADD and procaspase-8, converts into a death-inducing signaling complex (DISC) to induce apoptosis. Cyclic AMP (cAMP) is a second messenger that regulates various cellular processes such as cell proliferation, gene expression, and apoptosis. cAMP analogues are reported to act as anti-apoptotic agents in various cell types, including hepatocytes. We found that a cAMP analogue, dibutyryl cAMP (db-cAMP), inhibits TNF + ActD-induced apoptosis in rat hepatocytes. The protein kinase A (PKA) inhibitor KT-5720 reverses this inhibitory effect of cAMP on apoptosis. Cytoprotection by cAMP involves down-regulation of various apoptotic signal regulators like TRADD and FADD and inhibition of caspase-8 and caspase-3 cleavage. We also found

    The existence of multiple adenylate cyclase encoding genes implies the importance of Camp in Sinorhizobium meliloti 1021. In this study, as a pioneer step of understanding Camp roles, microarray analysis on S. Meliloti was carried out for the function of exogenous Camp. To our surprise, the result showed that the transcriptions of glnII and glnK genes were significantly upshifted in the presence of exogenous Camp in S. Meliloti. This phenomenon is further confirmed in S. Meliloti that the expression of either glnII or glnK promoter-lacZ translational fusion is higher in the presence of exogenous Camp.Therefore, for the first time, we have identified genes from S. Meliloti whose expression is activated by Camp. The potential physiological role of upregulation of glnII and glnK by Camp is discussed.

  19. cAMP signaling in blood platelets - old friends and new players.

    2015-11-01

    Full Text Available Atherothrombosis, the pathology underlying numerous cardiovascular diseases, is a major cause of death globally. Hyperactive blood platelets play a key role in the atherothrombotic process through the release of inflammatory mediators and formation of thrombi. In healthy blood vessels, excessive platelet activation is restricted by endothelial-derived prostacyclin (PGI2 through cyclic adenosine-5’-monophosphate (cAMP and protein kinase A (PKA-dependent mechanisms. Elevation in intracellular cAMP is associated with the control of a number of distinct platelet functions including actin polymerisation, granule secretion, calcium mobilisation and integrin activation. Unfortunately, in atherosclerotic disease the protective effects of cAMP are compromised, which may contribute to pathological thrombosis. The cAMP signalling network in platelets is highly complex with the presence of multiple isoforms of adenylyl cyclase (AC, PKA and phosphodiesterases (PDE. However, a precise understanding of the relationship between specific AC, PKA and PDE isoforms, and how individual signalling substrates are targeted to control distinct platelet functions is still lacking. In other cells types, compartmentalisation of cAMP signalling has emerged as a key mechanism to allow precise control of specific cell functions. A-kinase anchoring proteins (AKAPs play an important role in this spatiotemporal regulation of cAMP signalling networks. Evidence of AKAP-mediated compartmentalisation of cAMP signalling in blood platelets has begun to emerge and is providing new insights into the regulation of platelet function. Dissecting the mechanisms that allow cAMP to control excessive platelet activity without preventing effective haemostasis may unleash the possibility of therapeutic targeting of the pathway to control unwanted platelet activity.

The protein kinase A (PKA) inhibitor KT-5720 reverses this inhibitory effect of cAMP on apoptosis. Cytoprotection by cAMP involves down-regulation of various apoptotic signal regulators like TRADD and FADD and inhibition of caspase-8 and caspase-3 cleavage. We also found that cAMP exerts its affect at the proximal level of TNF signaling by inhibiting the formation of the DISC complex upon the binding of TNF to TNFR1. In conclusion, our study shows that cAMP prevents TNF+ActD-induced apoptosis in rat hepatocytes by inhibiting DISC complex formation.

    Concern has mounted over health effects caused by exposure to flame retardant additives used in consumer products. Significant research efforts have focused particularly on exposure to polybrominated diphenyl ethers (PBDEs) used in furniture and electronic applications. However, little attention has focused on applications in textiles, particularly textiles meeting a flammability standard known as CPAI-84. In this study, we investigated flame retardant applications in camping tents that met CPAI-84 standards by analyzing 11 samples of tent fabrics for chemical flame retardant additives. Furthermore, we investigated potential exposure by collecting paired samples of tent wipes and hand wipes from 27 individuals after tent setup. Of the 11 fabric samples analyzed, 10 contained flame retardant additives, which included tris(1,3-dichloroisopropyl) phosphate (TDCPP), decabromodiphenyl ether (BDE-209), triphenyl phosphate, and tetrabromobisphenol-A. Flame retardant concentrations were discovered to be as high as 37.5 mg/g (3.8% by weight) in the tent fabric samples, and TDCPP and BDE-209 were the most frequently detected in these samples. We also observed a significant association between TDCPP levels in tent wipes and those in paired hand wipes, suggesting that human contact with the tent fabric material leads to the transfer of the flame retardant to the skin surface and human exposure. These results suggest that direct contact with flame retardant-treated textiles may be a source of exposure. Future studies will be needed to better characterize exposure, including via inhalation and dermal sorption from air.

  5. Can You Hack It? Validating Predictors for IT Boot Camps

    Science.gov (United States)

    Gear, Courtney C.

    Given the large number of information technology jobs open and lack of qualified individuals to fill them, coding boot camps have sprung up in response to this skill gap by offering a specialized training program in an accelerated format. This fast growth has created a need to measure these training programs and understand their effectiveness. In the present study, a series of analyses examined whether specific or combinations of predictors were valid for training performance in this coding academy. Self-rated, daily efficacy scores were used as outcome variables of training success and correlation results showed a positive relationship with efficacy scores and the logic test score as a predictor. Exploratory analyses indicated a Dunning-Kruger effect where students with lower education levels experience higher overall mood during the training program. Limitations of the study included small sample size, severe range restriction in predictor scores, lack of variance in predictor scores, and low variability in training program success. These limitations made identifying jumps between training stages difficult to identify. By identifying which predictors matter most for each stage of skill acquisition, further research should consider more objective variables such as instructor scores which can serve as a guideline to better asses what stage learners join at and how to design curriculum and assignments accordingly (Honken, 2013).

  6. Linking cellular actin status with cAMP signaling in Candida albicans.

    2010-01-01

    The fungal pathogen Candida albicans has a remarkable ability to switch growth forms. Particularly, the yeast-to-hyphae switch is closely linked with its virulence. A range of chemicals and conditions can promote hyphal growth including serum, peptidoglycan, CO2, neutral pH, and elevated temperature. All these signals act essentially through the adenylyl cyclase Cyr1 that synthesizes cAMP. Cells lacking Cyr1 are completely defective in hyphal growth. Recently, cellular actin status is found to influence cAMP synthesis. However, how Cyr1 senses and processes multiple external and internal signals to produce a contextually proper level of cAMP remains unclear. We hypothesized that Cyr1 itself possesses multiple sensors for different signals and achieves signal integration through a combined allosteric effect on the catalytic center. To test this hypothesis, we affinity-purified a Cyr1-containing complex and found that it could enhance cAMP synthesis upon treatment with serum, peptidoglycan or CO2 in vitro. The data indicate that the complex is an essentially intact sensor/effector apparatus for cAMP synthesis. The complex contains two more subunits, the cyclase-associated protein Cap1 and G-actin. We discovered that G-actin plays a regulatory role, rendering cAMP synthesis responsive to actin dynamics. These findings shed new lights on the mechanisms that regulate cAMP-mediated responses in fungi.

    Full Text Available Background This study deals with the link between forced migration and sexual abuse, with a special focus on adolescent girls. Existing literature associates forced migration with sexual abuse and identifies adolescent girls as the most vulnerable. However, little is known about the situation of sexual abuse among Congolese refugees in Rwanda since their arrival in 2012 due to the conflict between Congolese government forces and the M23 rebel group. This study was initiated to explore the situation of sexual abuse of Congolese adolescent girls in Kigeme camp and to suggest remedial strategies. Participants and procedure Qualitative data were collected through individual interviews and focus group discussions (FGDs with adolescent girls. Interviews also involved parents, boys, camp authorities, and neighbouring citizens. Results The findings show that rape, unwanted physical touching, sexual exploitation, commercial sex, early marriage and girl trafficking are the main forms of sexual abuse. These are facilitated by the miserable life in the camp, shortcomings in the camp layout and security system, and adolescent developmental stage. They negatively impact girls’ reproductive health, social integration and mental health. Conclusions Existing strategies to address sexual abuse in the camp have had positive but insufficient results, and thus need to be improved and reinforced. Improvement is suggested in the areas of the abuse reporting system, the camp layout and security system, involvement of men and youth, and the consolidation of anti-GBV (gender-based violence clubs.

    2008-01-01

    cAMP-mediated signaling pathways regulate a multitude of important biological processes under both physiological and pathological conditions,including diabetes,heart failure and cancer.In eukaryotic cells,the effects of cAMP are mediated by two ubiquitously expressed intracellular cAMP receptors,the classic protein kinase A (PKA)/cAMP-dependent protein kinase and the recently discovered exchange protein directly activated by cAMP(Epac)/cAMP-regulated guanine nucleotide exchange factors.Like PKA,Epac contains an evolutionally conserved cAMP binding domain that acts as a molecular switch for sensing intracellular second messenger cAMP levels to control diverse biological functions.The existence of two families of cAMP effectors provides a mechanism for a more precise and integrated control of the cAMP signaling pathways in a spatial and temporal manner.Depending upon the specific cellular environments as well as their relative abundance,distrbution and localization,Epac and PKA may act independently,converge synergistically or oppose each other in regulating a specific cellular function.

  9. Regulation of cAMP Intracellular Levels in Human Platelets Stimulated by 2-Arachidonoylglycerol.

    2016-05-01

    We demonstrated that in human platelets the endocannabinoid 2-arachidonoylglycerol (2-AG) decreased dose- and time-dependently cAMP intracellular levels. No effect on cAMP decrease induced by 2-AG was observed in the presence of the adenylate cyclase inhibitor SQ22536 as well in platelets pretreated with the thromboxane A2 receptor antagonist, SQ29548 or with aspirin, inhibitor of arachidonic acid metabolism through the cyclooxygenase pathway. An almost complete recovering of cAMP level was measured in platelets pretreated with the specific inhibitor of phosphodiesterase (PDE) 3A, milrinone. In platelets pretreated with LY294002 or MK2206, inhibitors of PI3K/AKT pathway, and with U73122, inhibitor of phospholipase C pathway, only a partial prevention was shown. cAMP intracellular level depends on synthesis by adenylate cyclase and hydrolysis by PDEs. In 2-AG-stimulated platelets adenylate cyclase activity seems to be unchanged. In contrast PDEs appear to be involved. In particular PDE3A was specifically activated, as milrinone reversed cAMP reduction by 2-AG. 2-AG enhanced PDE3A activity through its phosphorylation. The PI3K/AKT pathway and PKC participate to this PDE3A phosphorylation/activation mechanism as it was greatly inhibited by platelet pretreatment with LY294002, MK2206, U73122, or the PKC specific inhibitor GF109203X. Taken together these data suggest that 2-AG potentiates its power of platelet agonist reducing cAMP intracellular level.

    Cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-regulated chloride channel localized at apical cell membranes and exists in macromolecular complexes with a variety of signaling and transporter molecules. Here, we report that the multidrug resistance protein 4 (MRP4), a cAMP transporter, functionally and physically associates with CFTR. Adenosine-stimulated CFTR-mediated chloride currents are potentiated by MRP4 inhibition, and this potentiation is directly coupled to attenuated cAMP efflux through the apical cAMP transporter. CFTR single-channel recordings and FRET-based intracellular cAMP dynamics suggest that a compartmentalized coupling of cAMP transporter and CFTR occurs via the PDZ scaffolding protein, PDZK1, forming a macromolecular complex at apical surfaces of gut epithelia. Disrupting this complex abrogates the functional coupling of cAMP transporter activity to CFTR function. Mrp4 knockout mice are more prone to CFTR-mediated secretory diarrhea. Our findings have important implications for disorders such as inflammatory bowel disease and secretory diarrhea.

    This article describes the creation and development of a sustainable, community-supported children's bereavement camp. Numerous grief camps were examined prior to the project development. The project development was guided by the S.M.A.R.T. (S--Strategic/specific; M--Measurable; A--Achievable/attainable; R--Realistic; and T--Time-framed) stratagem to direct steps toward the development of the bereavement camp. Outcome measures included program participation, as well as evaluations completed by campers, family members, and volunteers. Camp attendance continues to grow, with 48 children the first year and an average of 65 the following 3 years. According to post-evaluation surveys, campers were able to integrate back into school with a decrease in stress and an increase in their ability to verbalize their grief, share feelings and begin to trust others. One child "got her sparkle back" according to her grandmother. Several campers commented that camp allowed them to see themselves as normal children. The goal of Camp Healing Hearts was that campers would laugh again, and they are.

    Children with epilepsy attending a condition-specific overnight camp were evaluated for behavioral changes over 3 consecutive years, using a modification of the Vineland Adaptive Behavioral Scale. Trained counselors completed pre- and postcamp assessments for each camper. Repeated-measures MANOVA was used to analyze effects of the camp experience for each year, with respect to gender and age. Repeated-measures ANOVA was conducted to evaluate long-term effects from year-to-year comparisons for return campers, following three successive camp experiences. A significant change in social interaction was observed over 3 years. Despite some decline at the start of camp in consecutive years, the overall trend for return campers suggests a positive cumulative impact of continued camp participation, with improvements in the domains of social interaction, responsibility, and communication. A condition-specific camp designed for children with epilepsy can improve adaptive behaviors and social interactions. Overall net gains appear to increase over time, suggesting additional benefits for return campers.

    An enzyme of unknown function within the amidohydrolase superfamily was discovered to catalyze the hydrolysis of the universal second messenger, cyclic-3',5'-adenosine monophosphate (cAMP). The enzyme, which we have named CadD, is encoded by the human pathogenic bacterium Leptospira interrogans. Although CadD is annotated as an adenosine deaminase, the protein specifically deaminates cAMP to cyclic-3',5'-inosine monophosphate (cIMP) with a kcat/Km of 2.7 ± 0.4 × 10(5) M(-1) s(-1) and has no activity on adenosine, adenine, or 5'-adenosine monophosphate (AMP). This is the first identification of a deaminase specific for cAMP. Expression of CadD in Escherichia coli mimics the loss of adenylate cyclase in that it blocks growth on carbon sources that require the cAMP-CRP transcriptional activator complex for expression of the cognate genes. The cIMP reaction product cannot replace cAMP as the ligand for CRP binding to DNA in vitro and cIMP is a very poor competitor of cAMP activation of CRP for DNA binding. Transcriptional analyses indicate that CadD expression represses expression of several cAMP-CRP dependent genes. CadD adds a new activity to the cAMP metabolic network and may be a useful tool in intracellular study of cAMP-dependent processes.

    Full Text Available Background This study deals with the link between forced migration and sexual abuse, with a special focus on adolescent girls. Existing literature associates forced migration with sexual abuse and identifies adolescent girls as the most vulnerable. However, little is known about the situation of sexual abuse among Congolese refugees in Rwanda since their arrival in 2012 due to the conflict between Congolese government forces and the M23 rebel group. This study was initiated to explore the situation of sexual abuse of Congolese adolescent girls in Kigeme camp and to suggest remedial strategies. Participants and procedure Qualitative data were collected through individual interviews and focus group discussions (FGDs with adolescent girls. Interviews also involved parents, boys, camp authorities, and neighbouring citizens. Results The findings show that rape, unwanted physical touching, sexual exploitation, commercial sex, early marriage and girl trafficking are the main forms of sexual abuse. These are facilitated by the miserable life in the camp, shortcomings in the camp layout and security system, and adolescent developmental stage. They negatively impact girls’ reproductive health, social integration and mental health. Conclusions Existing strategies to address sexual abuse in the camp have had positive but insufficient results, and thus need to be improved and reinforced. Improvement is suggested in the areas of the abuse reporting system, the camp layout and security system, involvement of men and youth, and the consolidation of anti-GBV (gender-based violence clubs.

    Chhattisgarh has abundant herbal resources and a parallel AYUSH public health system. AYUSH health camps are conducted regularly in rural areas of the State by public and social sectors. The study aims to advocate the gravity of policy issues involved in AYUSH practices at health camps. A cross-sectional study was conducted in Pendra block of Bilaspur district, Chhattisgarh. Random sample of 600 people attending the camp were interviewed. A semi-structured questionnaire was used to collect data on disease complaints and established risk factors for asthma. Pearson's Chi-square test was used to calculate odds ratio (OR) with 95% confidence interval (CI). Analysis suggests that there was a significant decrease in reported asthmatic attacks (OR 6.68, 95% CI 4.05-11.01) among those who attended the camp. Established risk factors of asthma that were identified as prevalent in the community were using wood and biomass as fuel (OR 2.61, 95% CI 1.30-5.24) and damp walls (OR 1.88, CI 0.9-3.93). Practices at AYUSH health camps conducted by the public and nonpublic sectors need to be documented and reported. People have faith in traditional medicine, and the remedies and practices need to be further explicated and validated in context to health care-seeking practices. The importance of formulation of guidelines by the government for conducting AYUSH health camps is indicated.

    SUMMARY Cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-regulated chloride channel localized at apical cell membranes and exists in macromolecular complexes with a variety of signaling and transporter molecules. Here we report that the multidrug resistance protein 4 (MRP4), a cAMP transporter, is functionally and physically associates with CFTR. Adenosine-stimulated CFTR-mediated chloride currents are potentiated by MRP4 inhibition, and this potentiation is directly coupled to attenuated cAMP efflux through the apical cAMP transporter. CFTR single-channel recordings and FRET-based intracellular cAMP dynamics suggest that a compartmentalized coupling of cAMP transporter and CFTR occurs via the PDZ scaffolding protein, PDZK1, forming a macromolecular complex at apical surfaces of gut epithelia. Disrupting this complex abrogates the functional coupling of cAMP transporter activity to CFTR function. MRP4 knockout mice are more prone to CFTR-mediated secretory diarrhea. Our findings have important implications for disorders such as inflammatory bowel disease and secretory diarrhea. PMID:18045536

    Multiple virulence systems in the opportunistic pathogen Pseudomonas aeruginosa are regulated by the second messenger signalling molecule adenosine 3', 5'-cyclic monophosphate (cAMP). Production of cAMP by the putative adenylate cyclase enzyme CyaB represents a critical control point for virulence gene regulation. To identify regulators of CyaB, we screened a transposon insertion library for mutants with reduced intracellular cAMP. The majority of insertions resulting in reduced cAMP mapped to the Chp gene cluster encoding a putative chemotaxis-like chemosensory system. Further genetic analysis of the Chp system revealed that it has both positive and negative effects on intracellular cAMP and that it regulates cAMP levels by modulating CyaB activity. The Chp system was previously implicated in the production and function of type IV pili (TFP). Given that cAMP and the cAMP-dependent transcriptional regulator Vfr control TFP biogenesis gene expression, we explored the relationship between cAMP, the Chp system and TFP regulation. We discovered that the Chp system controls TFP production through modulation of cAMP while control of TFP-dependent twitching motility is cAMP-independent. Overall, our data define a novel function for a chemotaxis-like system in controlling cAMP production and establish a regulatory link between the Chp system, TFP and other cAMP-dependent virulence systems.

    Hyperpolarization-activated cyclic nucleotide-regulated cation (HCN) channels generate the hyperpolarization-activated cation current Ih present in many neurons. These channels are directly regulated by the binding of cAMP, which both shifts the voltage dependence of HCN channel opening to more positive potentials and increases maximal Ih at extreme negative voltages where voltage gating is complete. Here we report that the HCN channel brain-specific auxiliary subunit TRIP8b produces opposing actions on these two effects of cAMP. In the first action, TRIP8b inhibits the effect of cAMP to shift voltage gating, decreasing both the sensitivity of the channel to cAMP (K1/2) and the efficacy of cAMP (maximal voltage shift); conversely, cAMP binding inhibits these actions of TRIP8b. These mutually antagonistic actions are well described by a cyclic allosteric mechanism in which TRIP8b binding reduces the affinity of the channel for cAMP, with the affinity of the open state for cAMP being reduced to a greater extent than the cAMP affinity of the closed state. In a second apparently independent action, TRIP8b enhances the action of cAMP to increase maximal Ih. This latter effect cannot be explained by the cyclic allosteric model but results from a previously uncharacterized action of TRIP8b to reduce maximal current through the channel in the absence of cAMP. Because the binding of cAMP also antagonizes this second effect of TRIP8b, application of cAMP produces a larger increase in maximal Ih in the presence of TRIP8b than in its absence. These findings may provide a mechanistic explanation for the wide variability in the effects of modulatory transmitters on the voltage gating and maximal amplitude of Ih reported for different neurons in the brain.

None of the subjects in the control group was a prisoner either at a concentration camp or at any other prison or detention facility.Results: Multimorbidity affected mainly the central nervous system (CNS. Five years after leaving a camp, CNS dysfunctions were observed in 66% of former prisoners. Skeletal (42.4% and cardiovascular system (34.4% dysfunctions were the second and third most frequent dysfunctions. Thirty years after leaving a camp, the most prevalent coexisting conditions were also found within the CNS (80%, cardiovascular system (58.33%, and skeletal system (55%. Five and 30 years after leaving a camp, multiorgan lesions were found in 21.6% and 60% of survivors, respectively. Multimorbidity was more frequent in a group of prisoners who underwent the state of apathy and depression or who had been incarcerated longer than 24 months. The rate of CNS diseases was four times higher, and the rate of cardiovascular diseases or skeletal system dysfunctions was two times higher, in the study group after 30 years of leaving a camp compared with the control group

    Gidakiimanaaniwiagamig('Our Earth Lodge' in Ojibwe; gidaa, for short) camp program at Fond du Lac Reservation was started in 1989 by Pellerin and Greensky to help reservation students stay in school and graduate from middle school. As more students successfully completed middle school, the purpose of the program evolved to help students graduate from high school and go to college. Starting in 2003, various NSF awards funded the camps and STEM focus became explicit. The current gidaa camps are funded by NASA (Kowalczak) and NSF (Ito & Dalbotten) funds and focus on learning about the effect of climate change on the reservation and treaty lands. From its inception, the gidaa camps served a mixed age group of students (K through 12) who were mentored by elders, local school teachers and college students (camp alumni). A few university scientists provided support and acted as resources. The inclusion of students of all ages and their families is a deliberate one, based on the American Indian learning practice that "everyone teaches and everyone learns". This approach supports the development of the whole person and not just increased climate or general STEM literacy. Evidence for the success of this approach can be seen in 100% high school graduation rate of students who have been with the camp for more than a few years even if they did not attend every camp. Currently, weekend gidaa camps meet 6 times during the academic year with an additional week-long summer camp. Reservation Natural Resource managers share their concerns about the effect of climate change and what they already see and how they try to mitigate or adjust to these effects. Students thus immediately grasp the relevance of climate change to their lives while simultaneously being introduced to the work being done to help protect their land. Students are divided into small color groups (each group is of mixed ages) and group members help each other learn new concepts and vocabulary assisted by 1 or 2

    Background Propionibacterium acnes (P. acnes) is an anaerobic, Gram-positive bacteria encountered in inflammatory acne lesions, particularly in the pilosebaceous follicle. P. acnes triggers a strong immune response involving keratinocytes, sebocytes and monocytes, the target cells during acne development. Lipoteicoic acid and peptidoglycan induce the inflammatory reaction, but no P. acnes surface protein interacting with Toll-like receptors has been identified. P. acnes surface proteins have been extracted by lithium stripping and shown to induce CXCL8 production by keratinocytes. Methodology and principal findings Far-western blotting identified two surface proteins, of 24.5- and 27.5-kDa in size, specifically recognized by TLR2. These proteins were characterized, by LC-MS/MS, as CAMP factor 1 devoid of its signal peptide sequence, as shown by N-terminal sequencing. Purified CAMP factor 1 induces CXCL8 production by activating the CXCL8 gene promoter, triggering the synthesis of CXCL8 mRNA. Antibodies against TLR2 significantly decreased the CXCL8 response. For the 27 P. acnes strains used in this study, CAMP1-TLR2 binding intensity was modulated and appeared to be strong in type IB and II strains, which produced large amounts of CXCL8, whereas most of the type IA1 and IA2 strains presented little or no CAMP1-TLR2 binding and low levels of CXCL8 production. The nucleotide sequence of CAMP factor displays a major polymorphism, defining two distinct genetic groups corresponding to CAMP factor 1 with 14 amino-acid changes from strains phylotyped II with moderate and high levels of CAMP1-TLR2 binding activity, and CAMP factor 1 containing 0, 1 or 2 amino-acid changes from strains phylotyped IA1, IA2, or IB presenting no, weak or moderate CAMP1-TLR2 binding. Conclusions Our findings indicate that CAMP factor 1 may contribute to P. acnes virulence, by amplifying the inflammation reaction through direct interaction with TLR2. PMID:27902761

    Full Text Available Various studies show that more than 600,000 women in Nepal are suffering from prolapsed uterus and that 200,000 of those needed immediate surgery. Many of the women with prolapse could recall the exact moment they first felt the prolapse and found difficulty to share the problems due to fear of stigma. Stories ranged from seven days immediately after the first delivery to after the birth of the fifth or sixth child; during cooking rice to sneezing and long coughing; fetching water in a big bucket to working in the field. If detected at an early stage, uterine prolapse (UP can be controlled by pelvic exercises. For severe cases, the remedy is to insert a ring pessary to stop it from descending which has to be changed every four months. In extreme cases, uterine tissue protrudes from the vagina causing extreme discomfort. The only remedy is hysterectomy in which the uterus is surgically removed. The operation costs are about NRs 20,000. The Government of Nepal and other donor organizations have allocated funds to provide services to about 10,000 to 12,000 women suffering from uterine prolapse as humanitarian support each year and services are likely to be expanded in future. Women suffering from UP have not been able to get benefit from such assistance due to deep rooted socio-cultural perceptions and practices. The number of suffering women, on the other hand, would not decrease from existing curative management policy without hammering the root causes of UP. Moreover, a clear vision and strategy is needed to shift from humanitarian aid to a more sustainable public health intervention.Keywords: Camp Approach; Humanitarian Aid; Socio-cultural Practices; Sustainable Policy; Uterine Prolapse DOI: 10.3126/dsaj.v4i0.4511 Dhaulagiri Journal of Sociology and Anthropology Vol.4 2010 pp.21-40

    Mei Hua Gao

    Full Text Available OBJECTIVES: So many clinical trials of positive inotropes have failed, that it is now axiomatic that agents that increase cAMP are deleterious to the failing heart. An alternative strategy is to alter myocardial Ca(2+ handling or myofilament response to Ca(2+ using agents that do not affect cAMP. Although left ventricular (LV function is tightly linked to adenylyl cyclase (AC activity, the beneficial effects of AC may be independent of cAMP and instead stem from effects on Ca(2+ handling. Here we ask whether an AC mutant molecule that reduces LV cAMP production would have favorable effects on LV function through its effects on Ca(2+ handling alone. METHODS AND RESULTS: We generated transgenic mice with cardiac-directed expression of an AC6 mutant (AC6mut. Cardiac myocytes showed impaired cAMP production in response to isoproterenol (74% reduction; p<0.001, but LV size and function were normal. Isolated hearts showed preserved LV function in response to isoproterenol stimulation. AC6mut expression was associated with increased sarcoplasmic reticulum Ca(2+ uptake and the EC50 for SERCA2a activation was reduced. Cardiac myocytes isolated from AC6mut mice showed increased amplitude of Ca(2+ transients in response to isoproterenol (p = 0.0001. AC6mut expression also was associated with increased expression of LV S100A1 (p = 0.03 and reduced expression of phospholamban protein (p = 0.01. CONCLUSION: LV AC mutant expression is associated with normal cardiac function despite impaired cAMP generation. The mechanism appears to be through effects on Ca(2+ handling - effects that occur despite diminished cAMP.

  5. G beta gamma signaling reduces intracellular cAMP to promote meiotic progression in mouse oocytes.

    2007-02-01

    In nearly every vertebrate species, elevated intracellular cAMP maintains oocytes in prophase I of meiosis. Prior to ovulation, gonadotropins trigger various intra-ovarian processes, including the breakdown of gap junctions, the activation of EGF receptors, and the secretion of steroids. These events in turn decrease intracellular cAMP levels in select oocytes to allow meiotic progression, or maturation, to resume. Studies suggest that cAMP levels are kept elevated in resting oocytes by constitutive G protein signaling, and that the drop in intracellular cAMP that accompanies maturation may be due in part to attenuation of this inhibitory G protein-mediated signaling. Interestingly, one of these G protein regulators of meiotic arrest is the Galpha(s) protein, which stimulates adenylyl cyclase to raise intracellular cAMP in two important animal models of oocyte development: Xenopus leavis frogs and mice. In addition to G(alpha)(s), constitutive Gbetagamma activity similarly stimulates adenylyl cyclase to raise cAMP and prevent maturation in Xenopus oocytes; however, the role of Gbetagamma in regulating meiosis in mouse oocytes has not been examined. Here we show that Gbetagamma does not contribute to the maintenance of murine oocyte meiotic arrest. In fact, contrary to observations in frog oocytes, Gbetagamma signaling in mouse oocytes reduces cAMP and promotes oocyte maturation, suggesting that Gbetagamma might in fact play a positive role in promoting oocyte maturation. These observations emphasize that, while many general concepts and components of meiotic regulation are conserved from frogs to mice, specific differences exist that may lead to important insights regarding ovarian development in vertebrates.

    Laurel Clark Earth Camp is designed to inspire teachers and students to study their world through field experiences, remote sensing investigations, and hands on exploration, all of which lend context to scientific inquiry. In three different programs (for middle school students, for high school students, and for teachers) participants are challenged to understand Earth processes from the perspectives of both on-the ground inspection and from examination of satellite images, and use those multiple perspectives to determine best practices on both a societal and individual scale. Earth Camp is a field-based program that takes place both in the “natural” and built environment. Middle School Earth Camp introduces students to a variety of environmental science, engineering, technology, and societal approaches to sustainability. High School Earth Camp explores ecology and water resources from southern Arizona to eastern Utah, including a 5 day rafting trip. In both camps, students compare environmental change observed through repeat photography on the ground to changes observed from space. Students are encouraged to utilize their camp experience in considering their future course of study, career objectives, and lifestyle choices. During Earth Camp for Educators, teachers participate in a series of weekend workshops to explore relevant environmental science practices, including water quality testing, biodiversity surveys, water and light audits, and remote sensing. Teachers engage students, both in school and after school, in scientific investigations with this broad based set of tools. Earth Stories from Space is a website that will assist in developing skills and comfort in analyzing change over time and space using remotely sensed images. Through this three-year NASA funded program, participants will appreciate the importance of scale and perspective in understanding Earth systems and become inspired to make choices that protect the environment.

    Educators, policymakers, employers and other stakeholders in ocean and other geo-science fields face the continuing challenge of a lack of diversity in these fields. A particular challenge for educators and geo-science professionals promoting ocean sciences is to create programs that have broad access, including access for underrepresented youth. Experiential learning in environments such as intensive multi-day science and summer camps can be a critical captivator and motivator for young people. Our data suggest that youth, especially underrepresented youth, may benefit from exposure to the oceans and ocean science through intensive, sustained (eg more than just an afternoon), hands-on, science-based experiences. Data from the more than 570 youth who have participated in Camp SEA Lab's academically based experiential ocean science camp and summer programs provide compelling evidence for the importance of such programs in motivating young people. We have paid special attention to factors that might play a role in recruiting and retaining these young people in ocean science fields. Over 50% of program attendees were underrepresented youth and on scholarship, which gives us a closer look at the impact of such programs on youth who would otherwise not have the opportunity to participate. Both cognitive (knowledge) and affective (personal growth and motivation) indicators were assessed through surveys and questionnaires. Major themes drawn from the data for knowledge growth and personal growth in Camp SEA Lab youth attendees will be presented. These will be placed into the larger context of critical factors that enhance recruitment and retention in the geo-science pipeline. Successful strategies and challenges for involving families and broadening access to specialized programs such as Camp SEA Lab will also be discussed.

  8. Camp life: Are northern work camps safe havens for a migrant workforce, or dens of iniquity rampant with sex, drugs and alcohol?

    2004-02-01

    Two studies, dealing with life in work camps in northern Alberta and yielding contradictory results, are discussed. One study by a graduate student in sociology found that many of the men and women housed in work camps in remote locations of the northeastern oilsands belt use drugs, alcohol and casual sex to relieve boredom and loneliness. The other study, commissioned by the Athabasca Regional Issues Working Group (RWIG) found that camp workers visit Fort McMurray on the average of just over once a week, and use that time to take care of normal business, such as visiting health care professionals, buying gasoline, clothing, etc. It found no evidence of widespread sex, or drug or alcohol abuse among work camp residents. The RWIG study surveyed 25 per cent of the 6,272 worker population living in three camps in the Wood Buffalo region during June 2003. The study prepared by V. Taylor for a M.A. degree in sociology at the University of Calgary was severely criticized, primarily for its conclusions being based on a sample size of only nine men and one woman. Despite the criticism, the Taylor study made headlines across the country and has been instrumental in raising awareness of the special needs of a mobile workforce. A more broadly-based study is in progress at the University of Alberta, supported by the RCMP and a number of workplace stakeholders. Its objectives are to examine the situation more thoroughly, identify gaps in services and to explore long term solutions to what is undeniably a serious problem, indicated, if not proven, by the Taylor study.

    The cyclic adenosine monophosphate (cAMP), mitogen-activated protein kinase (MAPK) and cAMP response element-binding protein (CREB) transcriptional pathway is required for consolidation of hippocampus-dependent memory. In mice, this pathway undergoes a circadian oscillation required for memory persistence that reaches a peak during the daytime. Since mice exhibit polyphasic sleep patterns during the day, this suggested the interesting possibility that cAMP, MAPK activity and CREB phosphorylat...

  10. The role of type 4 phosphodiesterases in generating microdomains of cAMP: large scale stochastic simulations.

    Directory of Open Access Journals (Sweden)

    Rodrigo F Oliveira

    Full Text Available Cyclic AMP (cAMP and its main effector Protein Kinase A (PKA are critical for several aspects of neuronal function including synaptic plasticity. Specificity of synaptic plasticity requires that cAMP activates PKA in a highly localized manner despite the speed with which cAMP diffuses. Two mechanisms have been proposed to produce localized elevations in cAMP, known as microdomains: impeded diffusion, and high phosphodiesterase (PDE activity. This paper investigates the mechanism of localized cAMP signaling using a computational model of the biochemical network in the HEK293 cell, which is a subset of pathways involved in PKA-dependent synaptic plasticity. This biochemical network includes cAMP production, PKA activation, and cAMP degradation by PDE activity. The model is implemented in NeuroRD: novel, computationally efficient, stochastic reaction-diffusion software, and is constrained by intracellular cAMP dynamics that were determined experimentally by real-time imaging using an Epac-based FRET sensor (H30. The model reproduces the high concentration cAMP microdomain in the submembrane region, distinct from the lower concentration of cAMP in the cytosol. Simulations further demonstrate that generation of the cAMP microdomain requires a pool of PDE4D anchored in the cytosol and also requires PKA-mediated phosphorylation of PDE4D which increases its activity. The microdomain does not require impeded diffusion of cAMP, confirming that barriers are not required for microdomains. The simulations reported here further demonstrate the utility of the new stochastic reaction-diffusion algorithm for exploring signaling pathways in spatially complex structures such as neurons.

    Bacallao, Ketty; Monje, Paula V

    2015-01-01

    Isolated Schwann cells (SCs) respond to cAMP elevation by adopting a differentiated post-mitotic state that exhibits high levels of Krox-20, a transcriptional enhancer of myelination, and mature SC markers such as the myelin lipid galactocerebroside (O1). To address how cAMP controls myelination, we performed a series of cell culture experiments which compared the differentiating responses of isolated and axon-related SCs to cAMP analogs and ascorbate, a known inducer of axon ensheathment, basal lamina formation and myelination. In axon-related SCs, cAMP induced the expression of Krox-20 and O1 without a concomitant increase in the expression of myelin basic protein (MBP) and without promoting axon ensheathment, collagen synthesis or basal lamina assembly. When cAMP was provided together with ascorbate, a dramatic enhancement of MBP expression occurred, indicating that cAMP primes SCs to form myelin only under conditions supportive of basal lamina formation. Experiments using a combination of cell permeable cAMP analogs and type-selective adenylyl cyclase (AC) agonists and antagonists revealed that selective transmembrane AC (tmAC) activation with forskolin was not sufficient for full SC differentiation and that the attainment of an O1 positive state also relied on the activity of the soluble AC (sAC), a bicarbonate sensor that is insensitive to forskolin and GPCR activation. Pharmacological and immunological evidence indicated that SCs expressed sAC and that sAC activity was required for morphological differentiation and the expression of myelin markers such as O1 and protein zero. To conclude, our data indicates that cAMP did not directly drive myelination but rather the transition into an O1 positive state, which is perhaps the most critical cAMP-dependent rate limiting step for the onset of myelination. The temporally restricted role of cAMP in inducing differentiation independently of basal lamina formation provides a clear example of the uncoupling of signals

    The purpose of this study was to use sodium flufenamate, a compound that inhibits gonadotropin-releasing hormone (GnRH)-stimulated adenosine 3',5'-cyclic monophosphate (cAMP) production in the pituitary, to evaluate the potential role of cAMP as a mediator of GnRH-stimulated gonadotropin secretion from male pituitaries. Quartered male pituitaries were perifused at 37/sup 0/C and sequential effluent fractions collected every 10 min. Infusions of GnRH resulted in a twofold increase in luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion. Cycloheximide, 5 ..mu..M, completely inhibited the GnRH-stimulated LH and FSH secretion. Infusions of 0.1 mM flufenamate had similar effects on gonadotropin secretion as cycloheximide, whereas the administration of 5 mM dibutyryl cAMP in combination with GnRH and flufenamate restored the secretory responses of both hormones. The flufenamate-inhibited GnRH stimulated LH and FSH release, which was restored by DBcAMP and appeared to be protein synthesis dependent and specific for cAMP.These results suggest an indirect role for cAMP as a mediator of gonadotropin secretion from male pituitaries. However, in contrast to female pituitaries, the secretion of these hormones form male pituitaries is completely dependent on cAMP and de novo protein synthesis.

    Protected area management involves balancing environmental and social objectives. This is particularly difficult at high-use/high-impact recreation sites, because resource protection objectives may require substantial site management or visitor regulation. This study examined visitors? reactions to both of these types of actions at Annapolis Rocks, Maryland, a popular Appalachian Trail camping area. We surveyed visitors before and after implementation of camping policies that included shifting camping to designated newly constructed campsites and prohibiting campfires. Survey results reveal that visitors were more satisfied with all social and environmental indicators after the changes were enacted. An Importance-Performance analysis also determined that management actions improved conditions for factors of greatest concern to campers prior to the changes. Posttreatment visitors were least satisfied with factors related to reduced freedom and to some characteristics of the constructed campsites. Although there was evidence of visitor displacement, the camping changes met management goals by protecting the camping area?s natural resources and improving social conditions.

  16. The effect of hypoxia on PGE2-stimulated cAMP generation in HMEC-1.

    2015-06-01

    Prostaglandin E2 (PGE2) is generated in various cells, including endothelial cells, and is responsible for various functions, such as vascular relaxation and angiogenesis. Effects of PGE2 are mediated via receptors EP1-EP4, among which EP2 and EP4 are coupled to Gs protein which activates adenylate cyclase (AC) and cAMP synthesis. The aim of this work was to study the ability of human microvascular endothelial cells (HMEC-1) to synthesize cAMP in the presence of PGE2, and to determine the effect of hypoxia on the PGE2- stimulated cAMP level. It was decided to evaluate the effect of PGE2 on the secretion of VEGF, an inducer of angiogenesis. In summary, our findings show that PGE2 induces cAMP production, but hypoxia may impair PGE2-stimulated activity of the AC-cAMP signaling pathway. These results suggest that the cardioprotective effect of PGE2/EP4/cAMP may be attenuated during ischemia. Furthermore, this study indicates that the pro-angiogenic effect of PGE2 is not associated with VEGF secretion in HMEC-1 cells.

    The generation of cAMP by G protein-coupled receptors (GPCRs) and its termination are currently thought to occur exclusively at the plasma membrane of cells. Under existing models of receptor regulation, this signal is primarily restricted by desensitization of the receptors through their binding to β-arrestins. However, this paradigm is not consistent with recent observations that the parathyroid hormone receptor type 1 (PTHR) continues to stimulate cAMP production even after receptor internalization, as β-arrestins are known to rapidly bind and internalize activated PTHR. Here we show that binding to β-arrestin1 prolongs rather than terminates the generation of cAMP by PTHR, and that cAMP generation correlates with the persistence of arrestin-receptor complexes on endosomes. PTHR signaling is instead turned off by the retromer complex, which regulates the movement of internalized receptor from endosomes to the Golgi apparatus. Thus, binding by the retromer complex regulates the sustained generation of cAMP triggered by an internalized GPCR.

    The aim of the present study was to monitor the internal training load and profile of mood states (POMS) during a training camp in junior-elite triathletes. Sixteen (10 male and 6 female) young triathlon athletes (junior-elite: 18±1 yrs) were included in this study. All triathletes had been training for 7±3 years, and regularly trained 4 times a week 3h per session, throughout the year. The training camp (5 days) included two daily supervised training sessions. The CR-10RPE scale was used 30 minutes after every training session to evaluate session-RPE. POMS was administered 3 times during the training camp: at the beginning, on the 3rd day, and at the end of training camp. Session-RPE throughout the different training days showed significant differences (Panger decreased (P=0.015) the last day (8.6±2.2) with respect to the intermediate evaluation (9.6±2.7). The 45% increase in fatigue, the 24% decrease in vigour, and the intraindividual variability in session RPE that emerged, indicates that young triathletes need to be monitored closely during training camps in order to individualize training to avoid training maladaptation such as non-functional overreaching.

    In recent years, North African (NA) countries ceased to be emigration-only countries and are now on the verge of becoming immigration as well as transit countries for economic migrants and refugees. Contextual as well as structural long-term factors are driving these changes. The ongoing crises in Africa and the Middle East are prompting strong outflows of refugees, which are likely to induce NA countries to share some common public policy and public health concerns with European countries in a near future. This article highlights some aspects of these changes, from the study of the consequences of the 2011 Libyan crisis in Tunisia. It addresses individual trajectories and health concerns of refugees in and out North Africa from a study of the Choucha camp in Tunisia. The camp opened to immigrants from Libya during the 2011 crisis and accommodated the bulk of the refugees flow to Tunisia until July 2012. The study includes a monographic approach and a qualitative survey in the Choucha camp refugees. We describe the crisis history and the health response with a focus on the camp. We then address refugees' trajectories, and health needs and concerns from the interviews we collected in the camp in April 2012.

  1. Eviprostat Activates cAMP Signaling Pathway and Suppresses Bladder Smooth Muscle Cell Proliferation

    Full Text Available Eviprostat is a popular phytotherapeutic agent for the treatment of lower urinary tract symptoms (LUTS. At present, the signaling mechanisms underlying its therapeutic effects are still poorly understood. Given that cAMP has been reported to suppress cell hyperplasia and hypertrophy in various pathological situations, we asked whether the effect of Eviprostat could be ascribed to the activation of the cAMP signaling pathway. In the study, exposure of cAMP response element (CRE-secreted alkaline phosphatase (SEAP (CRE-SEAP-reporter cells to Eviprostat elevated SEAP secretion, which was associated with an increased phosphorylation of vasodilator-stimulated phosphoprotein (VASP and cAMP-response element-binding protein (CREB, as well as enhanced expression of CRE-regulated protein connexin43, indicating an activation of the cAMP signaling pathway. Consistent with these observations, Eviprostat-induced expression of Cx43 was abolished in the presence of adenylyl cyclase inhibitor SQ22536 or PKA inhibitor H89, whereas it was mimicked by adenylyl cyclase activator, forskolin. Further analysis demonstrated that Eviprostat significantly potentiated the effect of phosphodiesterase 3 (PDE3 inhibitor, but not that of PDE4 inhibitor, on CRE activation. Moreover, Eviprostat suppressed PDGF-induced activation of ERK and Akt and inhibited cell proliferation and hillock formation in both mesangial cells and bladder smooth muscle cells. Collectively, activation of the cAMP signaling pathway could be an important mechanism by which Eviprostat exerts its therapeutic effects for LUTS.

    Central neurons regenerate axons if a permissive environment is provided; after spinal cord injury, however, inhibitory molecules are present that make the local environment nonpermissive. A promising new strategy for inducing neurons to overcome inhibitory signals is to activate cAMP signaling. Here we show that cAMP levels fall in the rostral spinal cord, sensorimotor cortex and brainstem after spinal cord contusion. Inhibition of cAMP hydrolysis by the phosphodiesterase IV inhibitor rolipram prevents this decrease and when combined with Schwann cell grafts promotes significant supraspinal and proprioceptive axon sparing and myelination. Furthermore, combining rolipram with an injection of db-cAMP near the graft not only prevents the drop in cAMP levels but increases them above those in uninjured controls. This further enhances axonal sparing and myelination, promotes growth of serotonergic fibers into and beyond grafts, and significantly improves locomotion. These findings show that cAMP levels are key for protection, growth and myelination of injured CNS axons in vivo and recovery of function.

  3. cAMP level modulates scleral collagen remodeling, a critical step in the development of myopia.

    Yijin Tao

    Full Text Available The development of myopia is associated with decreased ocular scleral collagen synthesis in humans and animal models. Collagen synthesis is, in part, under the influence of cyclic adenosine monophosphate (cAMP. We investigated the associations between cAMP, myopia development in guinea pigs, and collagen synthesis by human scleral fibroblasts (HSFs. Form-deprived myopia (FDM was induced by unilateral masking of guinea pig eyes. Scleral cAMP levels increased selectively in the FDM eyes and returned to normal levels after unmasking and recovery. Unilateral subconjunctival treatment with the adenylyl cyclase (AC activator forskolin resulted in a myopic shift accompanied by reduced collagen mRNA levels, but it did not affect retinal electroretinograms. The AC inhibitor SQ22536 attenuated the progression of FDM. Moreover, forskolin inhibited collagen mRNA levels and collagen secretion by HSFs. The inhibition was reversed by SQ22536. These results demonstrate a critical role of cAMP in control of myopia development. Selective regulation of cAMP to control scleral collagen synthesis may be a novel therapeutic strategy for preventing and treating myopia.

  4. cAMP signaling in skeletal muscle adaptation: hypertrophy, metabolism, and regeneration

    Among organ systems, skeletal muscle is perhaps the most structurally specialized. The remarkable subcellular architecture of this tissue allows it to empower movement with instructions from motor neurons. Despite this high degree of specialization, skeletal muscle also has intrinsic signaling mechanisms that allow adaptation to long-term changes in demand and regeneration after acute damage. The second messenger adenosine 3′,5′-monophosphate (cAMP) not only elicits acute changes within myofibers during exercise but also contributes to myofiber size and metabolic phenotype in the long term. Strikingly, sustained activation of cAMP signaling leads to pronounced hypertrophic responses in skeletal myofibers through largely elusive molecular mechanisms. These pathways can promote hypertrophy and combat atrophy in animal models of disorders including muscular dystrophy, age-related atrophy, denervation injury, disuse atrophy, cancer cachexia, and sepsis. cAMP also participates in muscle development and regeneration mediated by muscle precursor cells; thus, downstream signaling pathways may potentially be harnessed to promote muscle regeneration in patients with acute damage or muscular dystrophy. In this review, we summarize studies implicating cAMP signaling in skeletal muscle adaptation. We also highlight ligands that induce cAMP signaling and downstream effectors that are promising pharmacological targets. PMID:22354781

    Analysis of G-protein-coupled receptor (GPCR) signaling, in particular of the second messenger cAMP that is tightly controlled by Gs- and Gi/o-proteins, is a central issue in biomedical research. The classical biochemical method to monitor increases in intracellular cAMP concentrations consists of a radioactive multicellular assay, which is well established, highly sensitive, and reproducible, but precludes continuous spatial and temporal assessment of cAMP levels in single living cells. For this purpose, Förster resonance energy transfer (FRET)-based Epac cAMP sensors are well suitable. So far, the latter sensors have been employed to monitor Gs-induced cAMP increases and it has remained elusive whether Epac sensors can reliably detect decreased intracellular cAMP levels as well. In this study, we systematically optimize experimental strategies employing FRET-based cAMP sensors to monitor Gi/o-mediated cAMP reductions. FRET experiments with adrenergic α2A or μ opioid receptors and a set of different Epac sensors allowed for time-resolved, valid, and reliable detection of cAMP level decreases upon Gi/o-coupled receptor activation in single living cells, and this effect can be reversed by selective receptor antagonists. Moreover, pre-treatment with forskolin or 3-isobutyl-1-methylxanthine (IBMX) to artificially increase basal cAMP levels was not required to monitor Gi/o-coupled receptor activation. Thus, using FRET-based cAMP sensors is of major advantage when compared to classical biochemical and multi-cellular assays.

    Full Text Available Cyclic AMP is a ubiquitous second messenger, which mediates many cellular responses mainly initiated by activation of cell surface receptors. Various Förster resonance energy transfer-based ratiometric cAMP indicators have been created for monitoring the spatial and temporal dynamics of cAMP at the single-cell level. However, single fluorescent protein-based cAMP indicators have been poorly developed, with improvement required for dynamic range and brightness. Based on our previous yellow fluorescent protein-based cAMP indicator, Flamindo, we developed an improved yellow fluorescent cAMP indicator named Flamindo2. Flamindo2 has a 2-fold expanded dynamic range and 8-fold increased brightness compared with Flamindo by optimization of linker peptides in the vicinity of the chromophore. We found that fluorescence intensity of Flamindo2 was decreased to 25% in response to cAMP. Live-cell cAMP imaging of the cytosol and nucleus in COS7 cells using Flamindo2 and nlsFlamindo2, respectively, showed that forskolin elevated cAMP levels in each compartment with different kinetics. Furthermore, dual-color imaging of cAMP and Ca2+ with Flamindo2 and a red fluorescent Ca2+ indicator, R-GECO, showed that cAMP and Ca2+ elevation were induced by noradrenaline in single HeLa cells. Our study shows that Flamindo2, which is feasible for multi-color imaging with other intracellular signaling molecules, is useful and is an alternative tool for live-cell imaging of intracellular cAMP dynamics.

    This is a report on a pilot project integrating children with end stage renal disease (ESRD) with well children for a summer camp experience. As the teen with ESRD prepares to enter the work force and college, he/she will have to adapt to a variety of situations that will not adapt to his/her unique medical condition. These issues motivated a pilot project in which 9 ESRD children were mainstreamed into a 2 week, YMCA summer camp experience. Pre and post questionnaires were developed and distributed to the camper, family, and the cabin counselor along with interviews to assess the value of the experience. All the children left camp more independent and knowledgeable about their self-care. The results of this pilot project indicate that children with ESRD can adapt to their environment and increase independence, self-care and self-esteem through supervised mainstreamed experiences.

  9. Involvement of the second messenger cAMP in gravity-signal transduction in physarum

    Block, I.; Rabien, H.; Ivanova, K.

    The aim of the investigation was to clarify, whether cellular signal processing following graviperception involves second messenger pathways. The test object was a most gravisensitive free-living ameboid cell, the myxomycete (acellular slime mold) Physarum polycephalum. It was demonstrated that the motor response is related to acceleration-dependent changes in the levels of the cellular second messenger cyclic adenosine monophosphate (cAMP). Rotating Physarum plasmodia in the gravity field of the Earth about a horizontal axis increased their cAMP concentration. Depriving the cells for a few days of the acceleration stimulus (near weightlessness in a space experiment on STS-69) slightly lowered plasmodial cAMP levels. Thus, the results provide first indications that the acceleration-stimulus signal transduction chain of Physarum uses an ubiquitous second messenger pathway.

    Animals were submitted to an associative learning task named Pavlovian/instrumental autoshaping (P/I-A) and treated with selective 5-HT1A and 5-HT7 receptor agonists and antagonists. Next, they were sacrificed, their brains removed, dissected and changes on cortical and hippocampal cyclic adenosine monophosphate (cAMP) production were determined. Results revealed that, the 8-OH-DPAT treatment facilitated memory consolidation of autoshaping and that effect was blocked completely by WAY100635 and partially by DR4004. WAY100635 or DR4004 alone had no effect on autoshaping. The cAMP results were complex and yielded no clear relationship to the memory results. Thus, cortical and hippocampal increased on cAMP production was observed following administration of the 5-HT(1A/7) agonist 8-OH-DPAT. The memory effect was, completely or partially, reversed by the selective antagonists WAY100635 (5-HT1A) or DR4004 (5-HT7), respectively.

    In recent years, the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) has attempted to go beyond its role as a provider of relief and basic services in Palestinian refugee camps and emphasize its role as a development agency. In this article, I focus on the Neirab Rehabilitation Project, an UNRWA-sponsored development project taking place in the Palestinian refugee camps of Ein el Tal and Neirab in northern Syria. I argue that UNRWA's role as a relief-centered humanitarian organization highlights the everyday suffering of Palestinian refugees, suffering that has become embedded in refugees’ political claims. I show that UNRWA's emphasis on “development” in the refugee camps is forcing Palestinian refugees in Ein el Tal and Neirab to reassess the political narrative through which they have understood their relationship with UNRWA.

    Established in 1951, Camp Desert Rock served as the training ground for America's 'Atomic Army'. For the next six years, U.S. ground troops traveled to the Nevada desert to participate in military maneuvers during atmospheric atomic weapons testing. Nearly 60,000 soldiers received physical and psychological training in atomic warfare. Abandoned when atmospheric testing ended, Camp Desert Rock was dismantled and its buildings moved to other locations. Today, the camp appears as a sterile expanse of desert marked by rock-lined tent platforms, concrete foundations, and trash scatters. Although visually unimposing, the site is rich with the history of America's nuclear testing program.

    The Hydromania II curriculum was written for the third in a series of summer science camp experiences targeting students in grades 4--6 who generally have difficulty accessing supplementary academic programs. The summer science camp in Portland is a collaborative effort between Bonneville Power Administration (BPA), the US Department of Energy (DOE), and the Portland Parks and Recreation Community Schools Program along with various other cooperating businesses and organizations. The curriculum has also been incorporated into other summer programs and has been used by teachers to supplement classroom activities. Camps are designed to make available, affordable learning experiences that are fun and motivating to students for the study of science and math. Inner-city, under-represented minorities, rural, and low-income families are particularly encouraged to enroll their children in the program.

    2010-02-01

    Cationic antimicrobial peptides (CAMPs), a component of the mammalian immune system, protect the host from bacterial infections. The roles of the Escherichia coli transcriptional regulators MarA, SoxS and Rob in susceptibility to these peptides were examined. Overexpression of marA, either in an antibiotic-resistant marR mutant or from a plasmid, decreased bacterial susceptibility to CAMPs. Overexpression of the soxS gene from a plasmid, which decreased susceptibility to antibiotics, unexpectedly caused no decrease in CAMP susceptibility; instead it produced increased susceptibility to different CAMPs. Deletion or overexpression of rob had little effect on CAMP susceptibility. The marRAB operon was upregulated when E. coli was incubated in sublethal amounts of CAMPs polymyxin B, LL-37 or human beta-defensin-1; however, this upregulation required Rob. Deletion of acrAB increased bacterial susceptibility to polymyxin B, LL-37 and human beta-defensin-1 peptides. Deletion of tolC yielded an even greater increase in susceptibility to these peptides and also led to increased susceptibility to human alpha-defensin-2. Inhibition of cellular proton-motive force increased peptide susceptibility for wild-type and acrAB deletion strains; however, it decreased susceptibility of tolC mutants. These findings demonstrate that CAMPs are both inducers of marA-mediated drug resistance through interaction with Rob and also substrates for efflux in E. coli. The three related transcriptional regulators show different effects on bacterial cell susceptibility to CAMPs.

    Although glucose is physiologically the most important regulator of insulin secretion, glucose-induced insulin secretion is modulated by hormonal and neural inputs to pancreatic β-cells. Most of the hormones and neurotransmitters evoke intracellular signals such as cAMP, Ca²⁺ , and phospholipid-derived molecules by activating G protein-coupled receptors (GPCRs). In particular, cAMP is a key second messenger that amplifies insulin secretion in a glucose concentration-dependent manner. The action of cAMP on insulin secretion is mediated by both protein kinase A (PKA)-dependent and Epac2A-dependent mechanisms. Many of the proteins expressed in β-cells are phosphorylated by PKA in vitro, but only a few proteins in which PKA phosphorylation directly affects insulin secretion have been identified. On the other hand, Epac2A activates the Ras-like small G protein Rap in a cAMP-dependent manner. Epac2A is also directly activated by various sulfonylureas, except for gliclazide. 8-pCPT-2'-O-Me-cAMP, an Epac-selective cAMP analogue, and glibenclamide, a sulfonylurea, synergistically activate Epac2A and Rap1, whereas adrenaline, which suppresses cAMP production in pancreatic β-cells, blocks activation of Epac2A and Rap1 by glibenclamide. Thus, cAMP signalling and sulfonylurea cooperatively activate Epac2A and Rap1. This interaction could account, at least in part, for the synergistic effects of incretin-related drugs and sulfonylureas in insulin secretion. Accordingly, clarification of the mechanism of Epac2A activation may provide therapeutic strategies to improve insulin secretion in diabetes.

    Summer Geophysics Field Camp is part of the core requirement for undergraduate Geophysics majors at Boise State University (CSM), as well as at Colorado School of Mines (CSM). We have found it to be most effectively taught when the target of the camp involves answering questions, which impact society. For example, currently the CSM/BSU geophysics summer camp focuses on ground water resources and geothermal potential in the Upper Arkansas River Basin, a part of the Rio Grande Rift system in Chaffee County, Colorado. A prime goal is to train students how to combine diverse sources of information into a unified interpretation: Students examine lithologies and structures on the periphery of the basin. Cross sections are constructed to predict the geophysical signature. Geophysical tools then are used to ascertain the gross structure and examine subsurface conditions in greater detail. These tools include surveying, regional gravity, deep and shallow seismic surveys, magnetics, DC resistivity, Ground Penetrating Radar, electromagnetics, hydrochemistry, and karaoke. While BSU and CSM own a considerable amount of geophysical hardware, our field camps are only possible because of extensive support by corporations and governmental agencies. In addition, the Society of Exploration Geohysics (SEG) Foundation provides financial support, Chaffee County assists with housing costs, and local land owners provide open access. In turn, the field camp results aid the community of Chaffee County in assessing their water resources for long term growth planning, as well as understanding the geothermal potential for hydroelectric power generation. BSU is currently exploring with the SEG Foundation under the Geophysicists Without Borders program to apply this model of combined education and social outreach in the form a geophysics camp for Southeast Asia, where we propose to study geohazards,geoarcheology and groundwater issues.

    Full Text Available Introduction: Professional burnout constitutes a syndrome of physical and mental exhaustion occurring in working environment with symptoms that are present after frequent and long-term exposure in difficult working conditions especially in special education settings where a higher burnout in noticed due to tne nature of the profession. Purpose: The purpose of this study was to examine professional burnout of working personnel in summer camps for people with disabilities. Materials – Methods: The sample consisted of 35 participants (11 men and 25 women all camp personnel escorting people with disabilities in summer camps. Each participant completed the Maslach Burnout Inventory (Maslach & Jackson, 1986 comprised of 22 items that assess the variables of exhaustion, accomplishment and depersonalization. Omega total reliability analysis revealed an internal consistency ranging from good (ω total= .72 to high (ω total = .91 and a positive interaction between all factors. Independent samples t-test revealed differences personal accomplishment (t = -1.9 , df = 33, p = 0.32 και depersonalization t = -2.59 , df = 33, p = .014 according to participation in physical activity during the summer camp period. ANOVA analysis showed statistically significant differences in depersonalization (F (3, 33 = 2.81, p = .043, η2 =.076 , exhaustion (F (3, 33 = .335, p = .032, η2 =.084 , and personal accomplishment (F (3, 33 = 4.67, p = .008, η2 =.090 in relation to work satisfaction and type of disability. Conclusions: Professional burnout of personnel working in summer camps for people with disabilities appears high due to many hours and high working load that is affected by the nature of disability, participation of personnel in physical activities and their satisfaction derived from primary profession other than summer camp work.

  20. Evidences for involvement of endogenous cAMP in Arabidopsis defense responses to Verticillium toxins

    Although there were reports suggesting the involvement of endogenous cAMP in plant defense signaling cascades,there is no direct evidence supporting this notion yet and the detailed mechanism is unclear. In the present study, we have used pathogenic fungi Verticillium dahliae and Arabidopsis plants as a model system of plant-microb interaction to demonstrate the function of endogenous cAMP in Arabidopsis defense responses. Both V. dahliae inoculation and Verticillium toxins injection induced typical "wilt" symptoms in Arabidopsis seedlings. When either 8-Br-AMP (a membrane permeable cAMP analogue) or salicylic acid (SA) was applied to Arabidopsis, the plants became resistant to V. dahliae toxins. However, addition of 8-Br-AMP did not increase the resistance of Arabidopsis transgenic plants deficient in SA to the toxins, suggesting that cAMP might act upstream of SA in plant defense signaling pathway.Indeed, 8-Br-cAMP and forskolin, an activator of adenylyl cyclase, significantly stimulated the endogenous SA level in plants, whereas DDA, an inhibitor of adenylyl cyclase dramatically reduced toxin-induced SA increase. Both the endogenous cAMP and SA increased significantly in Arabidopsis seedlings treated with toxins. Furthermore, transcription level of pathogenesis-related protein 1 gene (PR1) was strongly induced by both 8-Br-cAMP and the toxin treatment. Taken together, our data demonstrate that endogenous cAMP is involved in plant defense responses against Verticilliumsecreted toxins by regulating the production of the known signal SA in plant defense pathway.

  1. Measurement and evaluation of digital cervicography programs in two cervical cancer screening camps in East Africa

    Cervical cancer disproportionately affects women living in low- and middle-income countries. To address this global crisis, many governments and NGOs have implemented community-based screening and treatment programs at outreach camps. Here, high volumes of patients are able to access care: screening and diagnosis followed by immediate treatment of precancerous lesions onsite. However, monitoring and evaluation (M&E) of these efforts presents challenges, since each event typically relies on a different health workforce, and refers patients to different facilities for follow up and advanced care. To address these challenges, a digital imaging intervention was deployed at several screening camps in East Africa. Trained nurses screened women using a connected low-cost mobile colposcope built around a smartphone. A decision support job aid was integrated into the app controlling the device, guiding nurses and recording their diagnosis and treatment decisions. Aggregating the data from the job aid allowed M&E of the screening camp in real-time. In this paper, the M&E data from 2 different screening camps in East Africa are compared. Additionally, screening camps are compared to stationary clinics. Differences in the patient screening times, treatment rates, and individual nurse statistics were all documented through the job aid allowing for much improved epidemiological information following outreach events thus enabling targeted program improvements and provider training. Reporting data from screening camps were also shared online via public web pages, facilitating broader dissemination of health needs in specific East African communities, and sparking conversations with regional stakeholders about local disease burden.

    To corroborate alterations in the functional responses to beta-adrenergic receptor (beta-AR) stimulation with changes in beta-AR signaling in failing cardiomyocytes, contractile and L-type Ca(2+) current responses to isoproterenol along with stimulated cAMP generation were compared among cardiomyocytes isolated from canines with tachycardia-induced heart failure or healthy hearts. The magnitude of shortening of failing cardiomyocytes was significantly depressed (by 22 +/- 4.4%) under basal conditions, and the maximal response to isoproterenol was significantly reduced (by 45 +/- 18%). Similar results were obtained when the responses in the rate of contraction and rate of relaxation to isoproterenol were considered. The L-type Ca(2+) current amplitude measured in failing cardiomyocytes under basal conditions was unchanged, but the responses to isoproterenol were significantly reduced compared with healthy cells. Isoproterenol-stimulated cAMP generation was similar in sarcolemmal membranes derived from the homogenates of failing (45 +/- 6.8) and healthy cardiomyocytes (52 +/- 8.5 pmol cAMP. mg protein(-1). min(-1)). However, stimulated cAMP generation was found to be significantly reduced when the membranes were derived from the homogenates of whole tissue (failing: 67 +/- 8.1 vs. healthy: 140 +/- 27.8 pmol cAMP. mg protein(-1). min(-1)). Total beta-AR density was not reduced in membranes derived from either whole tissue or isolated cardiomyocyte homogenates, but the beta(1)/beta(2) ratio was significantly reduced in the former (failing: 45/55 vs. healthy: 72/28) without being altered in the latter (failing: 72/28, healthy: 77/23). We thus conclude that, in tachycardia-induced heart failure, reduction in the functional responses of isolated cardiomyocytes to beta-AR stimulation may be attributed to alterations in the excitation-contraction machinery rather than to limitation of cAMP generation.

    2013-04-01

    Full Text Available Cyclic nucleotides cAMP and cGMP are ubiquitous second messengers which regulate myriads of functions in virtually all eukaryotic cells. Their intracellular effects are often mediated via discrete subcellular signaling microdomains. In this review, we will discuss state-of-the-art techniques to measure cAMP and cGMP in biological samples with a particular focus on live cell imaging approaches, which allow their detection with high temporal and spatial resolution in living cells and tissues. Finally, we will describe how these techniques can be applied to the analysis of second messenger dynamics in subcellular signaling microdomains.

    A series of rock falls from the north face of Glacier Point above Camp Curry, Yosemite National Park, California, have caused reexamination of the rock-fall hazard because beginning in June, 1999 a system of cracks propagated through a nearby rock mass outlining a future potential rock fall. If the estimated volume of the potential rock fall fails as a single piece, there could be a risk from rock-fall impact and airborne rock debris to cabins in Camp Curry. The role of joint plane orientation and groundwater pressure in the fractured rock mass are discussed in light of the pattern of developing cracks and potential modes of failure.

    Anecdotally, burn camp has been reported to be a positive developmental and rehabilitative experience for attendees; there is little empirical data to support this belief. This study sought to explore whether burn camp either directly or indirectly elicits positive development outcomes in pediatric burn survivors or increases their psychosocial well-being and achievement. The Youth Experience Survey 2.0, a 66-item self-report inventory designed to measure developmental experiences in an organized youth activity, was administered to children aged 11 to 18 years attending summer burn camp. One hundred and ten burn-injured youth, 58 male and 52 female, reported that burn camp had positively impacted their lives through improved identity exploration, goal-setting and problem-solving abilities, increased physical activity, communication, emotional regulation, and time management skills (P camp for more than 5 years resulted in greater improvement. Study results support the burn camp experience as a far-reaching and positive developmental activity. Participants credited the camp experience with helping them with identity formation and reflection, improved social interactions, and increased initiative; all positive developmental outcomes for youth. Results suggest that burn camp participation not only helps burn-injured youth to deal with their burns but also assists them in the development of social and basic life skills, which will allow them to navigate the transition from youth to adulthood, more effectively and successfully.

  13. Cyclic AMP (cAMP) confers drug resistance against DNA damaging agents via PKAIA in CML cells.

    Xiao, Ling-Yi; Kan, Wai-Ming

    2017-01-05

    Cyclic adenosine monophosphate (cAMP) regulates many vital functions such as metabolism, proliferation, differentiation and death. Depending on cell types and stimulators, cAMP could either promote or attenuate cell death. cAMP signal can be transduced by protein kinase A (PKA) and/or exchange protein directly activated by cAMP (EPAC). In CML cells, cAMP may suppress their proliferation and enhance their differentiation. However, the role of cAMP on DNA damaging agent toxicity and the mechanism involved has not been studied. In this study, we studied the effect of cAMP on the sensitivity of CML cells to DNA damaging agents. We observed that forskolin (FSK) and dibutyryl-cAMP (DBcAMP) decreased cisplatin and etoposide-induced cell death in K562 cells. Moreover, PKA activator prevented K562 cells from DNA damaging agent-induced cell death while EPAC activator had no effect. Furthermore, we found that the PKA subtype, PKAIA, was involved in cAMP-attenuated resistance in K562 cells. Taken together, our results suggest that increased cAMP level confers CML cells to acquire a novel mechanism against DNA damaging agent toxicity via PKAIA. Thus, PKAIA inhibitor may be helpful in overcoming the resistance to DNA damaging agents in CML cells.

      To analyse the demographics surrounding and the sustainability of a course in Emergency Dental Care and Health Promotion developed and taught by a team of dentists from the United States to refugee camp health-care workers in two long-term refugee camps in Western Tanzania.   Refugee camp dental patient log books from Mtabila and Nyarugusu camps Kigoma, Tanzania were analysed and demographic data collected on each patient visit from the programme inception in November 2007 until August 2009. Data collection included information relevant to 1961 patient visits. Data were entered into SPSS Statistics 17.0 using the Freq application.   Patient visit data included demographics involving both the resident camp populations and the surrounding communities. The distribution of patients treated by nationality was: 58% Burundian (Mtabila), 14% Congolese (Nyarugusu), and 28% Tanzanian citizens residing near both camps. Extractions accounted for 95.5% of procedures performed. Recorded incidences of post-operative complications were 1> % of patient visits. Patient visits were steady over time and a referral system was implemented for complex cases. Health promotion sessions were held in both camps.   This dental programme has been self-sustaining and is providing some access to care where none existed previously. Programmes such as this may be one solution to the access to dental care problem in long-term refugee camps. © 2011 FDI World Dental Federation.

  10. Geochemistry of eastern North American CAMP diabase dykes

    Science.gov (United States)

    Callegaro, S.; Marzoli, A.; Bertrand, H.; Reisberg, L. C.; Chiaradia, M.; Bellieni, G.

    2011-12-01

    The Piedmont area of the Appalachians and the coastal plains of eastern North America (ENA) were intruded between 202 and 195 Ma[1,2] by swarms of diabase (dolerite) dykes and a few sills of the Central Atlantic magmatic province (CAMP). Different trends are observed for the dykes, from NW (more frequent in the South), to N-S and NE, thus a radial pattern and a coeval emplacement driven by the bulging effect of a mantle plume were initially inferred[3]. Conversely, based on field data, an age progression can be defined from NW- to N- and NE-oriented dykes, supporting a diachronous northward rift-to-drift transition during Pangaea break-up. New geochemical data on 74 ENA dykes suggest a dominant lithospheric mantle source for these magmatic suite. A deep enriched mantle source is further discarded by the crystallization temperatures (ca.1350°C) calculated[4] for high-Fo (up to Fo89) olivines, which do not reflect very hot (i.e. mantle-plume) potential mantle temperatures. Incompatible trace element contents are fairly homogeneous and generally low, e.g. (La/Yb)Ch (0.54-2.39), typical of melts derived from a quite depleted shallow (spinel) mantle-source. However, isotopic compositions of ENA dykes display a considerable spread in initial isotopic signatures, do not show correlation with incompatible trace elements, and are independent of the orientation and age of the dykes, i.e. 87Sr/86Sr200Ma (0.7043-0.7088), ɛNd200Ma (-6.67-+2.42) and 206Pb/204Pb200Ma (17.46-18.61). Pb isotopic compositions plot above the NHRL, at positive Δ7/4 (10-17) and Δ8/4 (19-73), calling for an enriched ancient component in the mantle source. Unradiogenic 187Os/188Os200Ma ratios (0.127-0.144) argue for negligible amounts of crustal contamination and, coupled with the large range of Sr-Nd-Pb isotopic compositions, suggest generation from a strongly heterogeneous mantle source, probably metasomatized lithosphere. Lithospheric mantle underlying the Appalachian orogen may have undergone

    Camp nurses deliver health care in a non-traditional setting. Research indicates that camp has a positive impact on campers with diabetes mellitus, but the impact on student nurse knowledge of diabetes care and confidence in the role as a member of the health care team is unknown. This study examined the experiences of student nurses at a summer residential camp for children with diabetes using a service-learning framework. Camp positively increased knowledge of diabetes in the nursing students. Reflective journals identified themes of anxiety, fatigue, responsibility, and increased confidence in the nursing student, while developing empathy for the lifestyle of children with diabetes. Future research on camp nursing is indicated.

    Full Text Available A sensitive and rapid method was developed for the determination of cAMP inLocusta migratoria manilensis Meyen by high-performance liquid chromatography withfluorescence detection. The cAMP was derivatized using chloroacetaldehyde and TBASbuffer/methanol was used as the mobile phase. A detection quantification of 40 fmol/mlcould be achieved when using fluorescence detection. An HPLC-MS method using DMHAas an ion-pair agent to analyze cAMP was also demonstrated. We studied the effect ofdopamine and other stimulants on cAMP levels from isolated locust central nervoussystems. The new method is well suited for the analysis of cAMP in small biologicalsamples.

    Children living with complex heart defects (CHD) are likely to have ongoing social, emotional, physical, and health concerns, and are in need of additional psychosocial support. Summer camps can provide therapeutic benefits. Little research exists regarding the value of shorter camping experiences from the perspectives of children with CHD. The aim of our study was to explore what children and adolescents with CHD considered meaningful when attending a therapeutic camping weekend in the company of peers with similar medical diagnoses. Engaging a phenomenological approach we used participant generated photography and reflective semi-structured interviews to explore participants' lived experience and value derived from their weekend camping experiences. The study was completed with thirteen participants ranging in age from 9 to 16 years. Interviews were recorded and transcribed verbatim. Data were analysed using Van Manen's guidelines. Three themes reflecting the camp experiences were generated from the data. Meaningful experiences spanned three outcomes which had some overlapping influences: (i) Developing relationships and feeling accepted by peers and counsellors at camp; (ii) Enjoying and learning during the weekend; and (iii) Experiencing the natural and human-built therapeutic environmental features of camp. The camping programme features, inputs, and processes as identified by the participants in contributing to these outcomes are described. This qualitative study showed that children living with complex CHD valued the opportunity for participating in weekend camping experiences in the company of peers with similar heart defects. Findings contribute to a better understanding of what programme features and processes were considered meaningful. Given the scarcity of resources to devote to such social support activities, the findings may help professionals to plan effective interventions to maximize benefits during a shorter camping experience. © 2013 John Wiley

  17. The intrusive record of the CAMP and what it means for the end Triassic mass extinction

    2017-04-01

    The end-Triassic mass extinction is one of the Phanerozoic's five largest mass extinctions. The extinction is usually attributed to climate change associated with degassing of erupting basalt from the Central Atlantic Magmatic Province (CAMP). However, recent work has shown that the earliest known CAMP basaltic flows occur stratigraphically above the extinction horizon indicating that the relationship between the CAMP and the extinction is more complex when resolved at higher temporal resolution. Here we present new high-precision U-Pb age determinations from intrusive units, which show that CAMP magmatic activity was occurring 100 ka before the oldest known eruptions. We show that the early magmatic activity correlates temporally with the onset of globally recognized changes to climatic and biotic records. We also report ages from sills in the Amazonas basin in Brazil that intrude synchronously with the extinction. We suggest that the release of thermogenic gases from the contact metamorphism of these sediments induced by injection of mafic sills may have contributed to the climate change that drove the extinction. Our results indicate that the intrusive record from large igneous provinces may be more important for linking to mass extinctions than the eruptive record.

  19. Evidence for cAMP as a mediator of gonadotropin secretion from female pituitaries

    Energy Technology Data Exchange (ETDEWEB)

    Bourne, G.A.; Baldwin, D.M.

    1987-09-01

    Sodium flufenamate, which inhibited gonadotropin-releasing hormone (GnRH)-stimulated increases in adenosine 3',5'-cyclic monophosphate (cAMP), was used to evaluate the potential role of cAMP as a mediator of GnRH-stimulated gonadotropin secretion. Quartered pituitaries from diestrous II female rats were perifused at 37/sup 0/C, and sequential effluent fractions were collected every 10 min. Administration of GnRH resulted in a characteristic biphasic response for both luteinizing hormone (LH) and follicle-stimulating hormone (FSH), whereas 5 ..mu..M cycloheximide inhibited the secondary augmented responses (phase II) of both hormones. Infusions of 0.1 mM flufenamate inhibited GnRH-stimulated gonadotropin secretion in a manner similar to that of cycloheximide, whereas the administration of 5 mM dibutyryl cAMP in combination with GnRH and flufenamate resulted in the restoration of LH and FSH secretion. The dibutyryl cAMP-restored response appeared to be protein synthesis dependent and specific for cAMP. These results suggest that although the cyclic nucleotide is not involved in the acute release of LH and FSH, it does appear to play a pivotal but indirect role in phase II release of the hormones, by effects involving the stimulation of de novo protein synthesis.

    Successful colonization and survival in variable environments require a competitive advantage during the initial growth phase after experiencing nutrient changes. Starved yeast cells anticipate exposure to glucose by activating the Hxt5p (hexose transporter 5) glucose transporter, which provides an advantage during early phases after glucose resupply. cAMP and glucose FRET (fluorescence resonance energy transfer) sensors were used to identify three signalling pathways that co-operate in the anticipatory Hxt5p activity in glucose-starved cells: as expected the Snf1 (sucrose nonfermenting 1) AMP kinase pathway, but, surprisingly, the sugar-dependent G-protein-coupled Gpr1 (G-protein-coupled receptor 1)/cAMP/PKA (protein kinase A) pathway and the Pho85 (phosphate metabolism 85)/Plc (phospholipase C) 6/7 pathway. Gpr1/cAMP/PKA are key elements of a G-protein-coupled sugar response pathway that produces a transient cAMP peak to induce growth-related genes. A novel function of the Gpr1/cAMP/PKA pathway was identified in glucose-starved cells: during starvation the Gpr1/cAMP/PKA pathway is required to maintain Hxt5p activity in the absence of glucose-induced cAMP spiking. During starvation, cAMP levels remain low triggering expression of HXT5, whereas cAMP spiking leads to a shift to the high capacity Hxt isoforms.

  10. Proteomic signatures implicate cAMP in light and temperature responses in Arabidopsis thaliana

    KAUST Repository

    Thomas, Ludivine

    2013-05-01

    The second messenger 3\\'-5\\'-cyclic adenosine monophosphate (cAMP) and adenylyl cyclases (ACs), enzymes that catalyse the formation of cAMP from ATP, are increasingly recognized as important signaling molecules in a number of physiological responses in higher plants. Here we used proteomics to identify cAMP-dependent protein signatures in Arabidopsis thaliana and identify a number of differentially expressed proteins with a role in light- and temperature-dependent responses, notably photosystem II subunit P-1, plasma membrane associated cation-binding protein and chaperonin 60 β. Based on these proteomics results we conclude that, much like in cyanobacteria, algae and fungi, cAMP may have a role in light signaling and the regulation of photosynthesis as well as responses to temperature and we speculate that ACs could act as light and/or temperature sensors in higher plants. Biological significance: This current study is significant since it presents the first proteomic response to cAMP, a novel and key second messenger in plants. It will be relevant to researchers in plant physiology and in particular those with an interest in second messengers and their role in biotic and abiotic stress responses. © 2013 Elsevier B.V.

    Identifying and addressing malnutrition among US-bound refugee children is an important human rights issue. Failure to address childhood malnutrition can impair cognitive development and productivity. The target population was children aged 6-59 months, originating from eight countries representing 51 % of US-resettled refugees for 2005-2011, living in 22 camps prior to potential US-resettlement. The corresponding camp-level nutritional survey data were evaluated. State Refugee Health Coordinators were surveyed on nutritional assessment, reporting and referrals for their US-refugee medical screenings. From 2004 to 2010, half of the camps (63 total surveys) had global acute malnutrition prevalence over 15 % at least once (surveys not done annually) and anemia prevalence greater than 40 %. The majority of US-refugee medical screenings included height and weight measurements but few used national or WHO standards to evaluate presence or level of malnutrition. Improve overseas camp monitoring and link these nutritional data to US-resettling refugee children to inform potential nutritional interventions. Domestically, use WHO or US growth standards for anthropometrics to determine presence of malnutrition and need for corrective action.

    Zalashik, Rakefet; Davidovitch, Nadav

    2006-09-01

    Two medical delegations, one from Palestine and one from the United States, were sent to detainment camps in Cyprus in the summer of 1947. The British Mandatory government had set up these camps in the summer of 1946 to stem the flow of Jewish immigrants into Palestine after World War II. The purpose of the medical delegations was to screen the camps' inhabitants and to propose a mental-health program for their life in Palestine. We examine the activities of these two delegations within the context of their scientific interest in the psycho-pathology of displaced persons after World War II and as part of a broader project of mental hygiene. According to the delegations, the detainees would be a potential source of strength for building a new society if they adapted to life in Palestine. However, they would become a burden if they failed to be absorbed. At the same time, the medical delegations also saw the detainee camps as a potential "living laboratory" for scientific exploration. The case of the two medical delegations in Cyprus is also a story about constructing and transgressing medical borders. Apart from the obvious fact that this case study deals with movement of people, refugees as well as health-care workers, it is also about the transmission of knowledge and professions across the ocean.

  8. Adenyl cyclases and cAMP in plant signaling - Past and present

    KAUST Repository

    Gehring, Christoph A.

    2010-06-25

    In lower eukaryotes and animals 3\\'-5\\'-cyclic adenosine monophosphate (cAMP) and adenyl cyclases (ACs), enzymes that catalyse the formation of cAMP from ATP, have long been established as key components and second messengers in many signaling pathways. In contrast, in plants, both the presence and biological role of cAMP have been a matter of ongoing debate and some controversy. Here we shall focus firstly on the discovery of cellular cAMP in plants and evidence for a role of this second messenger in plant signal transduction. Secondly, we shall review current evidence of plant ACs, analyse aspects of their domain organisations and the biological roles of candidate molecules. In addition, we shall assess different approaches based on search motifs consisting of functionally assigned amino acids in the catalytic centre of annotated and/or experimentally tested nucleotide cyclases that can contribute to the identification of novel candidate molecules with AC activity such as F-box and TIR proteins. 2010 Gehring; licensee BioMed Central Ltd.

    2012-11-01

    Full Text Available This pilot study addressed the impact of a summer camp experience on at-risk middle school youth by exploring self-reported growth in skill development and resilience. Campers who attended a five-weeksummer day camp were compared to a control group who maintained typical activities throughout the summer. Results showed statistically significant differences in the campers’ belief of a good future for themselves (U = 179.40, P = 0.05. Campers reported sustained or positive growth in domains of social skills and positive values from the baseline to a six-month follow up. Three significant themes emerged from individual in-depth interviews including: (a engagement influences skill competence, (b the campenvironment expands positive choice and availability of positive occupations, and (c males developed skills and resilience from informal physical activity while no equivalent existed for females. Middle school aged at-risk youth can benefit from occupation-based summer camp programs that promote active engagement in an enriched environment and sustain gains once they return to high-risk environments. This research contributes to a growing understanding of the potential contribution of occupational therapy in the design and delivery of effective summer camp experiences for at-risk youth.

  10. Mental Health Outcomes for Youth Living in Refugee Camps: A Review.

    Science.gov (United States)

    Vossoughi, Nadia; Jackson, Yo; Gusler, Stephanie; Stone, Katie

    2016-10-11

    Currently, there are approximately 10.8 million child refugees worldwide. Youth living in refugee camps face a wide range of difficulties placing them at risk for trauma exposure and negative mental health outcomes. However, little is known about the mental health functioning of these youth. The present review provides a systematic review of mental health outcomes for refugee/displaced youth residing in refugee camps. Twenty studies were included in the present review. Among these studies, the prevalence of mental health disorders varied greatly with some studies reporting null effects for disorders like posttraumatic stress disorder and others reporting prevalence as high as 87%. Levels of anxiety, somatic symptoms, depression, and aggression also varied across studies. The results point to the significant need for more research on the mental health of youth residing in refugee camps. Despite the wide range of measurement approaches, the evidence points to a fairly consistent finding of a range of maladjustment problems for youth living in refugee camps. Implications for improving the methodology for investigating mental health are discussed. © The Author(s) 2016.

  11. The central role of cAMP in regulating Plasmodium falciparum merozoite invasion of human erythrocytes.

    Directory of Open Access Journals (Sweden)

    Amrita Dawn

    2014-12-01

    Full Text Available All pathogenesis and death associated with Plasmodium falciparum malaria is due to parasite-infected erythrocytes. Invasion of erythrocytes by P. falciparum merozoites requires specific interactions between host receptors and parasite ligands that are localized in apical organelles called micronemes. Here, we identify cAMP as a key regulator that triggers the timely secretion of microneme proteins enabling receptor-engagement and invasion. We demonstrate that exposure of merozoites to a low K+ environment, typical of blood plasma, activates a bicarbonate-sensitive cytoplasmic adenylyl cyclase to raise cytosolic cAMP levels and activate protein kinase A, which regulates microneme secretion. We also show that cAMP regulates merozoite cytosolic Ca2+ levels via induction of an Epac pathway and demonstrate that increases in both cAMP and Ca2+ are essential to trigger microneme secretion. Our identification of the different elements in cAMP-dependent signaling pathways that regulate microneme secretion during invasion provides novel targets to inhibit blood stage parasite growth and prevent malaria.

    Video Podcasts offer a unique opportunity to actively engage the public in ongoing research projects by revealing faces and stories from field, lab and engineering efforts that often happen behind the scenes. Podcasts thus allow the science community to not only present their accomplishments, but also the where, how and why. Publishing these videos in real time while stationed at remote field camps brings particular challenges to the process. This was the case during the POLNET (Polar Earth Observing Network) field seasons at Byrd Camp, West Antarctica. With no internet connection and limited flights in and out of camp, the team worked to produce a series of Video Podcast field updates that were flown to McMurdo Station and uploaded to a web server off the continent. These videos provided glimpses of living and working on a remote ice sheet while installing GPS and seismic stations. At a time when climate science is under extreme scrutiny, this project offered a tangible and human view of efforts to model how ice masses are changing. In any science education effort, the risk of diluting the science until it is no longer meaningful poses certain challenges. At the same time, going into great depth about the methods and theories using technical vocabulary can immediately turn away an audience that is already inundated with information. These videos represent an attempt to creatively and accurately present scientific concepts in short, digestible segments that bring elements of fun from the unique field setting and personalities of Byrd Camp, West Antarctica.

    Missing from the growing literature on Jewish camps is Lukinsky's (1968) pioneering study of the curriculum to teach responsibility that he designed for the 1966 Ramah American Seminar. Reviewing this work I discovered that Lukinsky--under Schwab's (1971) influence--creates a rare balance between his own perspectives as an educational practitioner…

    The present study was designed to test the hypothesis that a session of summer camp would increase the self-esteem of economically disadvantaged, school-age children from New York's inner-city neighborhoods. This study was conducted at a small, coeducational residential summer camp in the Pocono Mountains designed for children ages 6-12 years from low-income areas of New York City. During each of four 12-day sessions, the Piers-Harris Children's Self-concept Scale was administered as a pretest and posttest to a sample of 68 children (36 boys and 32 girls; 33 African American, 34 Hispanic, and 1 Asian) of 742 attending camp for the sumnmer. Children scored significantly higher on the measure of self-esteem at the end of camp than at the beginning. Positive descriptions and ratings of self on popularity increased significantly. Observations and interviews with children suggested physical and social environmental features, such as contact with nature and having the same counselor as a previous year, may support self-esteem. Findings are discussed within a framework for biophilia, an innate urge to affiliate with nature which unfolds from earliest childhood on.
