    Radiation sterilization is the best method of sterilization, essentially for single use medical and surgical products. Pakistan has established a commercial gamma irradiation plant for this purpose. This article overviews the advantages and benefits of radiation sterilization to stimulate the interest of industrialists and the users in this technology. This technology can give a better medical care in the country and the growing demand can only be met by bulk sterilization. The radiation sterilized medical products can also compete well with the products sterilized by other methods in the international market, gamma sterilization is accepted internationally and if adopted it can boost our export of medical products.

    Ice, R D

    1995-11-01

    Radionuclide production for medical use originally was incidental to isotope discoveries by physicists and chemists. Once the available radionuclides were identified they were evaluated for potential medical use. Hevesy first used 32P in 1935 to study phosphorous metabolism in rats. Since that time, the development of cyclotrons, linear accelerators, and nuclear reactors have produced hundreds of radionuclides for potential medical use. The history of medical radionuclide production represents an evolutionary, interdisciplinary development of applied nuclear technology. Today the technology is represented by a mature industry and provides medical benefits to millions of patients annually.

  5. Emphasizing humanities in medical education: Promoting the integration of medical scientific spirit and medical humanistic spirit.

    Song, Peipei; Tang, Wei

    2017-05-23

    In the era of the biological-psychological-social medicine model, an ideal of modern medicine is to enhance the humanities in medical education, to foster medical talents with humanistic spirit, and to promote the integration of scientific spirit and humanistic spirit in medicine. Throughout the United States (US), United Kingdom (UK), other Western countries, and some Asian countries like Japan, many medical universities have already integrated the learning of medical humanities in their curricula and recognized their value. While in China, although medical education reform over the past decade has emphasized the topic of medical humanities to increase the professionalism of future physicians, the integration of medical humanity courses in medical universities has lagged behind the pace in Western countries. In addition, current courses in medical humanities were arbitrarily established due to a lack of organizational independence. For various reasons like a shortage of instructors, medical universities have failed to pay sufficient attention to medical humanities education given the urgent needs of society. The medical problems in contemporary Chinese society are not solely the purview of biomedical technology; what matters more is enhancing the humanities in medical education and fostering medical talents with humanistic spirit. Emphasizing the humanities in medical education and promoting the integration of medical scientific spirit and medical humanistic spirit have become one of the most pressing issues China must address. Greater attention should be paid to reasonable integration of humanities into the medical curriculum, creation of medical courses related to humanities and optimization of the curriculum, and actively allocating abundant teaching resources and exploring better methods of instruction.

    Pramudita, A.

    2012-01-01

    This paper reviews efforts on using high energy (25-30 MeV) and high power (10-20 kW) electron linacs and lower energy (7 MeV) proton linacs for medical radioisotope production. Using high energy x-rays from the electron linacs, PET (Positron Emission Tomography) radioisotopes are produced through photonuclear reactions such as 19 F(γ,n) 18 F, which also allow production of other PET radionuclides 11 C, 13 N, and 15 O. Other mostly used medical radionuclides 99m Tc can also be obtained by using the electron linacs, through photofission or photonuclear reactions. Proton linacs for PET have also been recently developed and the product has been available in the market since 2005. The linacs have been tested for 18 F production. As a proton accelerator, the target systems and nuclear reactions are similar to the ones used in PET cyclotrons. (author)

  14. Advertising and promotion of smokeless tobacco products.

    Science.gov (United States)

    Ernster, V L

    1989-01-01

    This paper is focused on the approaches used to advertise and promote smokeless tobacco products during the early to mid-1980s. These included traditional motifs that featured rugged-looking masculine models in sporting and outdoor settings as well as an expanded white-collar appeal. Smokeless tobacco was not affected by the ban on broadcast advertising of cigarettes that went into effect in 1971, and, until 1986, both print and broadcast media were used to advertise it. Promotional activities ranged from sponsorship of sporting events to offers for clothing bearing smokeless tobacco product logos. Despite the claims of manufacturers that advertising and promotional efforts were not targeted to youth, smokeless tobacco companies sponsored tobacco-spitting contests with teenage participants, a college marketing program, and college scholarships. In efforts that appeared designed to bolster their public image in the face of growing concern over the consequences of smokeless tobacco use by young people, companies like U.S. Tobacco Company contributed to major social programs, including, ironically, alcohol- and drug-abuse prevention programs. Spurred by public health groups, federal legislation was passed in 1986 that banned television and radio advertising of smokeless tobacco products and required manufacturers to include warning labels on their products on the potential health hazards of smokeless tobacco use.

    United States academic hospitals have rapidly adopted the hospitalist model of care. Academic hospitalists have taken on much of the clinical and teaching responsibilities at many institutions, yet little is known about their academic productivity and promotion. We sought to discover the attitudes and attributes of academic hospitalists regarding mentorship, productivity, and promotion. We performed a web-based email survey of academic hospitalists consisting of 61 questions. Four hundred and twenty academic hospitalists. Demographic details, scholarly production, presence of mentorship and attitudes towards mentor, academic rank Two hundred and sixty-six (63%) of hospitalists responded. The majority were under 41 (80%) and had been working as hospitalists for 20% "protected" time, AOR = 1.92 (95% CI 1.00, 3.69), and 3) a better-than-average understanding of the criteria for promotion, AOR = 3.66 (95% CI 1.76, 7.62). A lack of mentorship was negatively associated with producing any peer-reviewed first author publications AOR = 0.43 (95% CI 0.23, 0.81); any non-peer reviewed publications AOR = 0.45 (95% CI 0.24, 0.83), and leading a teaching session at a national meeting AOR = 0.41 (95% CI 0.19, 0.88). Most hospitalists promoted to the level of associate professor had been first author on four to six peer-reviewed publications. Most academic hospitalists had not presented a poster at a national meeting, authored an academic publication, or presented grand rounds at their institution. Many academic hospitalists lacked mentorship and this was associated with a failure to produce scholarly activity. Mentorship may improve academic productivity among hospitalists.

    Worksite-based programs to improve workforce health and well-being (Workplace Health Promotion (WHP)) have been advanced as conduits for improved worker productivity and decreased health care costs. There has been a countervailing health economics contention that return on investment (ROI) does not merit preventive health investment. METHODS/PROCEDURES: Pertinent studies were reviewed and results reconsidered. A simple economic model is presented based on conventional and alternate assumptions used in cost benefit analysis (CBA), such as discounting and negative value. The issues are presented in the format of 3 conceptual dilemmas. In some occupations such as nursing, the utility of patient survival and staff health is undervalued. WHP may miss important components of work related health risk. Altering assumptions on discounting and eliminating the drag of negative value radically change the CBA value. Simple monetization of a work life and calculation of return on workforce health investment as a simple alternate opportunity involve highly selective interpretations of productivity and utility.

    Radioisotopes play important roles in numerous areas ranging from medical treatments to national security and basic research. Radionuclide production technology for medical applications has been pursued since the early 1900s both commercially and in nuclear science centers. Many medical isotopes are now in routine production and are used in day-to-day medical procedures. Despite these advancements, research is accelerating around the world to improve the existing production methodologies as well as to develop novel radionuclides for new medical appli-cations. Electron linear accelerators (linacs) represent a unique method for the production of radioisotopes. Even though the basic technology has been around for decades, only recently have electron linacs capable of producing photons with sufficient energy and flux for radioisotope production become available. Housed in Argonne Nation-al Laboratory’s Low Energy Accelerator Facility (LEAF) is a newly upgraded 55 MeV/25-kW electron linear ac-celerator, capable of producing a wide range of radioiso-topes. This talk will focus on the work being performed for the production of the medical isotopes 99Mo (99Mo/99mTc generator), 67Cu, and 47Sc.

    Full Text Available The isotope production technology was overviewed, including traditional and newest technology. The current situation of medical isotope production was introduced. The problems faced by isotope supply and demand were analyzed. The future development trend of medical isotopes and technology prospect were put forward. As the most populous country, nuclear medicine develops rapidly, however, domestic isotope mainly relies on imports. The highly productive and relatively safe MIPR is expected to be an effective way to breakthrough the bottleneck of the development of nuclear medicine. Traditional isotope production technologies with reactor can be improved. It's urgent to research and promote new isotope production technologies with reactor. Those technologies which do not depend on reactor will have a bright market prospects.

    2015-12-01

    Full Text Available The aim of this paper is to propose a brief introspection in the literature review in an attempt to highlight the peculiarities of traditional foodstuffs that enable them to be promoted as the primary food for a healthy diet. The trend of healthy eating is gaining ground not only for experts and researchers, but also for consumers on a daily basis. Traditional foodstuffs are brought back into the consumers’ attention in a market full of highly-processed foodstuffs. Marketing specialists noticed the link between the two concepts and they elaborated promotional strategies for traditional foodstuffs, having the ‘healthy diet’ as insight. Throughout the paper we will present theoretical considerations such as the concept of ‘traditional food product’, ‘promotion’, and ‘healthy diet’ from a marketing perspective followed by several examples of traditional food products perceived as healthy, and lastly, we will highlight the benefits of promoting a healthy diet by consuming traditional food products.

    Bioethics tries to define the medical activity and any other related activity needed to maintain the function of a health institution, through the development of principles and moral values. Bioethics is quite broad and has a background that combines various disciplines such as medicine, philosophy, law, sociology, and theology. Advertising and promotion are part of the strategy aimed at developing and maintaining relationships with the targeted audience (patients). To regulate this activity, it was necessary to develop ethical rules of healthcare marketing. The content of promotional messages must be truthful and should not create unjustified expectations. The doctor or the healthcare unit must be able to provide the services claimed in the advertisement. From an ethical point of view, marketing communication should be more consistent with reality, even if its purpose is to shed light on more attractive issues. In this context, the categories and groups vulnerable to certain content of the advertising message should be mentioned. A patient with a serious suffering will be easily influenced and will tend to trust any promise easily, with the desire to heal. Ethically, the information presented must not alter the reality and should not give false hopes to patients. Those responsible for marketing in the healthcare field must keep in mind the ethics code of the medical profession, must maintain an honest marketing communication, which does not create inaccurate expectations, must not denigrate other colleagues, and must use a message whose content should respect the dignity of the profession.

  7. Systematic procedures to promote U.S. HIV medication adherence via Photovoice.

    2017-06-21

    Medication adherence is essential to promote the health of people living with HIV (PL-HIV) and prevent HIV transmission in the U.S. Novel medication health promotion interventions are needed that address patient-centeredness, understandability, and communication with providers. The aims of this article are to define the systematic stages we used to develop an effective health promotion intervention via the products (e.g. images and stories) of Photovoice. We designed an intervention to improve HIV adherence knowledge, attitudes, and communication with providers through Photovoice. 16 PL-HIV used Photovoice strategies to describe their experiences with medication via images and captions and create an intervention (10 adherence promotion posters) that integrated photo-stories of their adherence motivators, journeys from sickness to health, and how they manage and counter HIV stigma. We outline the systematic process we used to adapt Photovoice to create the effective intervention for replication. The process included six stages: (i) identify scope of the project; (ii) create collaborative project team; (iii) design project materials; (iv) review and revise materials with team members; (v) disseminate materials; and (vi) evaluate materials. Photovoice is used traditionally as a social action research method. In this project, it was adapted to create patient-driven images and stories for health promotion posters. Poster viewers experienced improved self-efficacy for HIV medication adherence. Describing the adaptation of the Photovoice process in a deliberate and transparent way can support fidelity to the essence of the participant-driven method, while also allowing researchers and practitioners to replicate Photovoice as a successful health promotion intervention. © The Author 2017.

    To (1) discuss buzz marketing, contrast it with traditional forms of promotional communications, and provide guidelines for use and (2) describe a successful buzz-marketing program used by Sentara Healthcare to decrease overuse and inappropriate use of antibiotic medications. An English-language-only literature search of ABI Inform, Lexus-Nexus, InfoTrac, and university library databases from 1980 to the present using the keywords buzz, word of mouth, opinion leader, and thought leader. Articles and books were cross referenced for other works of interest. Performed by the author for their contribution to an exploratory analysis of this topic. Performed by the author. Buzz marketing is an indirect communications method that has been used successfully in the promotion of a wide variety of products, services, and ideas. By identifying and cultivating nonmedia opinion leaders, the technique generates word-of-mouth communications between these early adopters of products and services and the early and late majority of people who tend to follow their lead. Opinion leaders can be categorized as ordinary or extraordinary, technical or social, and specialist or generalist, depending on the nature of their communications, expertise, and range of knowledge. Buzz marketing is most useful for ideas that are memorable, produce small changes in behavior that have big effects over time, and have the potential to reach a "tipping point" in terms of momentum among a target population. Pharmacists can use buzz marketing for promoting innovative services such as pharmaceutical care. A case study is presented on the use of buzz marketing by a health system for decreasing antibiotic resistance through lessening of public demand for antibiotics and support of physicians in prescribing the agents appropriately. Buzz marketing is a potent force in the promotion of pharmaceuticals and can be used by pharmacists. It works best when patients perceive the benefits of innovations. Providing

    Lapi, Suzanne

    2014-03-01

    The increase in use of radioisotopes for medical imaging and therapy has led to the development of novel routes of isotope production. For example, the production and purification of longer-lived position emitting radiometals has been explored to allow for nuclear imaging agents based on peptides, antibodies and nanoparticles. These isotopes (64Cu, 89Zr, 86Y) are typically produced via irradiation of solid targets on smaller medical cyclotrons at dedicated facilities. Recently, isotope harvesting from heavy ion accelerator facilities has also been suggested. The Facility for Rare Isotope Beams (FRIB) will be a new national user facility for nuclear science to be completed in 2020. Radioisotopes could be produced by dedicated runs by primary users or may be collected synergistically from the water in cooling-loops for the primary beam dump that cycle the water at flow rates in excess of hundreds of gallons per minute. A liquid water target system for harvesting radioisotopes at the National Superconducting Cyclotron Laboratory (NSCL) was designed and constructed as the initial step in proof-of-principle experiments to harvest useful radioisotopes in this manner. This talk will provide an overview of isotope production using both dedicated machines and harvesting from larger accelerators typically used for nuclear physics.

    2016-07-01

    This cross-sectional study examined price-related promotions for tobacco products on Twitter. Through the Twitter Firehose, we obtained access to all public tweets posted between 6 December 2012 and 20 June 2013 that contained a keyword suggesting a tobacco-related product or behaviour (eg, cigarette, vaping) in addition to a keyword suggesting a price promotion (eg, coupon, discount). From this data set of 155 249 tweets, we constructed a stratified sampling frame based on the price-related keywords and randomly sampled 5000 tweets (3.2%). Tweets were coded for product type and promotion type. Non-English tweets and tweets unrelated to a tobacco or cessation price promotion were excluded, leaving an analytic sample of 2847 tweets. The majority of tweets (97.0%) mentioned tobacco products while 3% mentioned tobacco cessation products. E-cigarettes were the most frequently mentioned product (90.1%), followed by cigarettes (5.4%). The most common type of price promotion mentioned across all products was a discount. About a third of all e-cigarette-related tweets included a discount code. Banned or restricted price promotions comprised about 3% of cigarette-related tweets. This study demonstrates that the vast majority of tweets offering price promotions focus on e-cigarettes. Future studies should examine the extent to which Twitter users, particularly youth, notice or engage with these price promotion tweets. Published by the BMJ Publishing Group Limited.

    In 2008 and 2009, the Supreme Court reviewed the question of whether patients injured by dangerous prescription drugs or medical devices can bring tort lawsuits against pharmaceutical and device manufacturers. The Court ruled that claims against device manufacturers were preempted while claims against pharmaceutical manufacturers were not. The threat of product liability lawsuits promotes patient safety by encouraging manufacturers to take greater responsibility in providing clear warnings about known adverse effects of their products.

    Full Text Available Abstract. Objectives The aim of the study is to develop a system of practical measures to ensure the most effective promotion of construction products to the market. Method During the process of research, methods of logical, statistical and comparative analysis as well as expert evaluations were used. Results Analysis and assessment of the construction market situation enabled a group of factors that affect the sales of construction products – in particular, building materials – to be identified, which constituted an empirical basis for developing a strategy for their promotion, aimed at maximum satisfaction of solvent demand and profit. It is determined that as an instrument of the communication policy of a construction enterprise, the promotion of construction products is a system of incentive measures and techniques designed to stimulate sales. A characterisation of the promotional system of construction products as an instrument of marketing communications is presented, revealing the target dependence of measures to stimulate sales from stages of the life cycle. The criteria for selecting the promotion channels have been systematised, serving as the basis for the strategic approach to the organisation of the distribution logistic system in construction and the steady positioning of construction products on the market. Conclusion A strategic approach to the promotion of construction products in the market ensures the creation of a system of effectively integrated marketing communications, implemented in the form of a strategic bridging partnership. Realisation of the strategy of construction product promotion comprises a reliable basis for strengthening the market positions of construction companies under the harsh conditions of a competitive environment.

    Most of the microorganisms isolated from the medical products were inactivated by the irradiation of 1.0-1.5 Mrad. However, some microorganisms were inactivated as the factor of 10 8 cells by the irradiation of 2.0-2.3 Mrad. Micrococcus roseus was a radioresistant strain, and on the view point of 10 8 cell number the dose for inactivating the Micrococcus roseus in a liquid and lyophilized condition was 2.3 and 3.5 Mrad, respectively. It has been found that the radiosensitivity of microorganism was influenced differently according to the suspended solution, oxygen, temperature and others. Radiosterlization of vaccine could not be performed due to the degeneration of vaccine. Cotton products were suitable where as disposable plastic set such as PVC product was not much suitable due to the reduction of pH or formation of oxidasable matter. Antibiotics in dry state was suitable where as dextrose solution or saline solution was unsuitable packing sheets (P.E, P.P, PVC) were suitable up to 2.5 Mrad dose. There was no relationships between cell growth rate and dose level in toxicity experiment of the irradiated plastic sets. Micrococcus roseus and Escherichia coli were effectively inactivated by treating heat pre-, post- or simultaneous irradiation. (author)

    Ten million cubic meters (361 million cubic feet) of disposable medical products (DMP) and related health care items are estimated to be sterilized in the world. In this paper, current conditions and perspectives of gamma sterilization is discussed in comparison with ethylene oxide gas and electron beams. Of the total sterilization estimates for DMP, 2.8 million cubic meters (99 million cubic feet) are sterilized with gamma radiation, with a market share of 27%. Gamma radiation is becoming increased from both general market growth and the introduction of new products, as well as the conversion of product from ethylene oxide gas to cobalt-60. Regulatory pressures, legal considerations, and increasing publicity surrounding ethylene oxide usage are encouraging manufactures to switch to gamma radiation. Gamma's performance features include: no temperature change during the sterilization, high penetration, even through hermetically sealed packages, no residues, and no post-sterilization treatment or quarantine period. Gamma sterilization is economically beneficial in large volumes of product. Cost saving to the end user of gamma sterilization has meant lower minimum dose levels than 25 KGy. Despite of an increasingly accepted gamma radiation, there are still four factors to be considered, including cobalt-60 availability, price, transportation, and disposal. The price of cobalt-60 is based on neutron cost. In the future, cobalt-60 price is expected to be flat and enables gamma processing to become even more competitive with other sterilization methods. Gamma radiation using cobalt-60 has been proven as a safe, effective, and cost-competitive sterilization method for treating DMP and related health care items. It's wide use and many processing advantages will continue to make it a preferred sterilization method. (N.K.)

  9. Radioisotope Production for Medical and Physics Applications

    Radioisotopes are critical to the science and technology base of the US. Discoveries and applications made as a result of the availability of radioisotopes span widely from medicine, biology, physics, chemistry and homeland security. The clinical use of radioisotopes for medical diagnosis is the largest sector of use, with about 16 million procedures a year in the US. The use of ^99Mo/^99mTc generator and ^18F make up the majority, but ^201Tl, ^123I, ^111In, and ^67Ga are also used routinely to perform imaging of organ function. Application of radioisotopes for therapy is dominated by use of ^131I for thyroid malignancies, ^90Y for some solid tumors, and ^89Sr for bone cancer, but production of several more exotic species such as ^225Ac and ^211At are of significant current research interest. In physics ^225Ra is of interest for CP violation studies, and the actinides ^242Am, ^249Bk, and ^254Es are needed as targets for experiments to create superheavy elements. Large amounts of ^252Cf are needed as a fission source for the CARIBU experiment at ANL. The process of radioisotope production is multidisciplinary. Nuclear physics input based on nuclear reaction excitation function data is needed to choose an optimum target/projectile in order to maximize desired isotope production and minimize unwanted byproducts. Mechanical engineering is needed to address issues of target heating, induced mechanical stress and material compatibility of target and claddings. Radiochemists are involved as well since chemical separation to purify the desired final radioisotope product from the bulk target and impurities is also usually necessary. Most neutron rich species are produced at a few government and university reactors. Other radioisotopes are produced in cyclotrons in the commercial sector, university/hospital based facilities, and larger devices at the DOE labs. The landscape of US facilities, the techniques involved, and current supply challenges will be reviewed.

    With the purpose of producing high purity carrier-free 201 Tl, for medical use, a production and separation method was developed using the CV-28 Cyclotron of the Nuclear Engineering Institute in Rio de Janeiro, Brazil. 201 Pb was produced by 24 MeV proton bombardment of natural Tl and allowed to decay to 201 Tl. In the separation process the target is dissolved in HNO 3 , the 201 Pb produced is separated by Fe(OH) 3 coprecipitation, and the Fe is latter separated by anion exchange. The 201 Pb is permited to decay during 32 hrs. 201 Tl is then separated from remaining Pb by anion exchange. The chemical separation is done in a remote processing cell using manipulators, tongs, electric and pneumatic systems. The thick target yield of 201 Pb is 1.7 mCi/μAhr. At the moment the production is restricted to 4 mCi of 201 Tl for each irradiation. (Author) [pt

    Studies investigating the impact of promotion and tenure on surgeon productivity are lacking. The aim of this study is to elucidate the relationship of promotion and tenure to surgeon productivity. We reviewed data for the Department of Surgery at our institution. Relative value units (RVUs) billed per year, publications per year, and grant funding per year were used to assess productivity from 2010 to 2016. We analyzed tenure-track (TT) and non-tenure-track (NT) surgeons and compared the productivity within these groups by rank: assistant professor (ASST), associate professor (ASSOC), and full professor (FULL). Kruskal-Wallis and Mann-Whitney U tests were used to assess significance and relationships between the groups. A TT faculty was promoted if they produced more research, with the highest publication rates in TT FULL. TT faculty publishing rates increased from ASST to ASSOC (1 versus 2, P = 0.006) and from ASSOC to FULL (2 versus 4, P production (RVUs) was highest between TT ASSOC and NT FULL. TT faculty increased productivity between ASST and ASSOC (7023 versus 8384, P = 0.001) and decreased between ASSOC and FULL (8384 versus 6877, P production and grant funding, whereas NT FULL has the highest clinical production.

    2018-03-01

    Full Text Available Constitutively active promoter elements for heterologous protein production in Lactococcus lactis are scarce. Here, the promoter of the PTS-IIC gene cluster from L. lactis NZ3900 is described. This promoter was cloned upstream of an enhanced green fluorescent protein, GFPmut3a, and transformed into L. lactis. Transformants produced up to 13.5 μg of GFPmut3a per milliliter of log phase cells. Addition of cellobiose further increased the production of GFPmut3a by up to two-fold when compared to glucose. Analysis of mutations at two specific positions in the PTS-IIC promoter showed that a ‘T’ to ‘G’ mutation within the −35 element resulted in constitutive expression in glucose, while a ‘C’ at nucleotide 7 in the putative cre site enhanced promoter activity in cellobiose. Finally, this PTS-IIC promoter is capable of mediating protein expression in Bacillus subtilis and Escherichia coli Nissle 1917, suggesting the potential for future biotechnological applications of this element and its derivatives.

    The cyclotron of Hammersmith hospital in England was completed and started the operation in 1955. The feature is in its design operable at high beam current, reaching 500μA in internal beam and 300μA in external beam. In 1960's, twelve nuclides of radioactive pharmaceuticals were produced with the cyclotron. C-11, N-13 and O-15 have been used in the form of radioactive gases such as CO or H 2 O to test lung functions. F-18 has been used for bone scanning. K-43 is employed in the research of electrolyte balancing together with Na-24 and Br-77. Fe-52 is utilized in iron ion researches as a tracer. Cs-129 is highly evaluated as an isotope for imaging cardiac clogging part. Radioisotopes must be much more used in the examination of in vivo metabolic function. For this purpose, peculiarly labelled compounds should be further developed. It is welcome that the persons paying attention to the medical prospect of cyclotrons are increasing. The author hopes to continue his endeavour to find new products made with the cyclotron for human welfare. (Wakatsuki, Y.)

    2011-12-01

    A significant number of adults with HIV in the USA do not maintain adherence to highly active antiretroviral therapy (HAART) at adequate levels. Although traditional cognitive behavioral interventions have shown promise in promoting HAART adherence, acceptance-based behavior therapy (ABBT) may be particularly useful in this population. ABBT has the potential to overcome common avoidance-based barriers associated with poor adherence, including denial of various illness-related factors and avoidance of stigmatization. We describe the rationale for promoting psychological and behavioral acceptance in HIV-positive populations; outline an ABBT to promote HAART adherence targeting primary care patients from urban, minority, low socioeconomic backgrounds; and report preliminary qualitative observations of treatment feasibility and acceptability.

    Facebook has a comprehensive set of policies intended to inhibit promotion and sales of tobacco products. Their effectiveness has yet to be studied. Leading tobacco brands (388) were identified via Nielsen and Ranker databases and 108 were found to maintain brand-sponsored Facebook pages. Key indicators of alignment with Facebook policy were evaluated. Purchase links (eg, 'shop now' button) on brand-sponsored pages were found for hookah tobaccos (41%), e-cigarettes (74%), smokeless (50%) and cigars (31%). Sales promotions (eg, discount coupons) were present in hookah tobacco (48%), e-cigarette (76%) and cigar (69%) brand-sponsored pages. While conventional cigarettes did not maintain brand-sponsored pages, they were featured in 80% of online tobacco vendors' Facebook pages. The requirement for age gating, to exclude those online tobacco stores which promote leading cigarette brands (eg, Marlboro, Camel). Many of the brand-sponsored tobacco product pages had thousands of 'likes'. It is laudable that Facebook has policies intended to interdict tobacco promotion throughout its platform. Nevertheless, widespread tobacco promotion and sales were found at variance with the company's policies governing advertising, commerce, page content and under age access. Vetting could be improved by automated screening in partnership with human reviewers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The inappropriate use of medication represents a major threat to public health and drugs rank first among the agents causing intoxication in Brazil, ahead of poisons for rodents and insects, illegal drugs, pesticides, cleaning products and spoiled food. The National Curriculum of Secondary Education Parameters (PCN+) give major emphasis to health, since the reference to Drugs is mentioned repeatedly in the text. The scope of this research was to study the approaches to drug use in textbooks. For this purpose, eleven biology textbooks were analyzed, namely six single volumes and five with three volumes each, i.e. a total of twenty-one volumes. The rational use of medication should be considered an important topic for the promotion of health which affects all sectors of society and should be emphasized in basic education. In line with this idea and based on the results obtained, it is suggested that the textbooks analyzed should be adapted to the new legislation and content that addresses Rational Drug Use, thus meeting the recommendations of PCN+. In this context, the books should concisely address the following topics: self-medication, adherence to drug treatment, advertisements and reports on drugs, among others.

Using the method of frequency analysis, the analysis of data from five pharmacies within a period of three months (more than 17,000 records) revealed how individual subgroups of medical appliances and their concrete items are represented in both types of dispensation. The method of the semistructured questionnaire (10 respondents) was used to find what problems are encountered in dispensation, and which medical appliances and their subgroups are the sources of the problems. The respondents regard the contemporary level of knowledge concerning medical appliances gained in pregradual studies as insufficient.

    Considerable controversy persists regarding the use of human antibiotics to promote growth in animals raised for food. The authors examined the economic effect of removing antibiotics used for growth promotion in commercial broiler chickens. The authors utilized data published by the Perdue company, the fourth largest poultry producer in the United States, in which a non-randomized controlled trial of growth-promoting antibiotic (GPA) use was conducted with seven million broiler chickens to evaluate the impact of removing GPAs on production. Positive production changes were associated with GPA use, but were insufficient to offset the cost of the antibiotics. The net effect of using GPAs was a lost value of 0.0093 dollars per chicken (about 0.45% of total cost). Based upon these data, the authors found no basis for the claim that the use of GPAs lowers the cost of production. Note that this study does not include veterinary cost changes or changes in performance variability associated with the removal of GPAs. This economic analysis is the first study to the authors' knowledge utilizing large-scale empirical data collected by U.S. industry, in which it is demonstrated that the use of GPAs in poultry production is associated with economic losses to the producers. These data are of considerable importance in the ongoing national debate concerning the continued use of antibiotics for growth promotion of food animals. Based on the industry study and the resulting economic impact, the use of GPAs in U.S. poultry production should be reconsidered.

    The gender demographics within urology are changing as more women are entering the workforce. Since research productivity strongly influence career advancement, we aim to characterize gender differences in scholarly productivity and promotions in a cohort of graduated academic urologists. Urologists who graduated between 2002 and 2008 from 34 residency programs affiliated with the top 50 urology hospitals as ranked in 2009 by U.S. News & World Report were followed longitudinally. Only urologists affiliated with an academic teaching hospital were included for analysis. A total of 543 residents graduated, 459 (84.5%) males and 84 (15.5%) females. Of these, 173 entered academia, 137 (79.2%) males and 36 (20.8%) females. Women had fewer publications compared to men (mean 19.3 versus 61.7, p = 0.001). Fewer women compared to men were promoted from assistant professor 11 (30.6%) versus 83 (60.6%), p = 0.005. Fewer women achieved associate professor 10 (27.8%) versus 67 (48.9%), p = 0.005 or professor ranks 1 (2.8%) versus 16 (11.7%), p = 0.005 respectively compared to men. In a multivariate logistic regression analysis, after controlling for the number of total publications and number of years since graduation, gender was not predictive of achieving promotion, OR = 0.81 (95% CI 0.31-2.13), p = 0.673. Women are underrepresented in senior faculty roles in urology. Scholarly productivity seems to play a major role in academic promotion within urology. With increasing women in academic urology, further studies are needed to explore predictors of promotion and how women can achieve higher leadership roles in the field.

  9. Promoting cancer screening within the patient centered medical home.

    While consensus has grown that primary care is the essential access point in a high-performing health care system, the current model of primary care underperforms in both chronic disease management and prevention. The Patient Centered Medical Home model (PCMH) is at the center of efforts to reinvent primary care practice, and is regarded as the most promising approach to addressing the burden of chronic disease, improving health outcomes, and reducing health spending. However, the potential for the medical home to improve the delivery of cancer screening (and preventive services in general) has received limited attention in both conceptualization and practice. Medical home demonstrations to date have included few evidence-based preventive services in their outcome measures, and few have evaluated the effect of different payment models. Decreasing use of hospitals and emergency rooms and an emphasis on improving chronic care represent improvements in effective delivery of healthcare, but leave opportunities for reducing the burden of cancer untouched. Data confirm that what does or does not happen in the primary care setting has a substantial impact on cancer outcomes. Insofar as cancer is the leading cause of death before age 80, the PCMH model must prioritize adherence to cancer screening according to recommended guidelines, and systems, financial incentives, and reimbursements must be aligned to achieve that goal. This article explores capacities that are needed in the medical home model to facilitate the integration of cancer screening and other preventive services. These capacities include improved patient access and communication, health risk assessments, periodic preventive health exams, use of registries that store cancer risk information and screening history, ability to track and follow up on tests and referrals, feedback on performance, and payment models that reward cancer screening.

    2013-01-01

    Background Medical tourists, persons that travel across international borders with the intention to access non-emergency medical care, may not be adequately informed of safety and ethical concerns related to the practice of medical tourism. Researchers indicate that the sources of information frequently used by medical tourists during their decision-making process may be biased and/or lack comprehensive information regarding individual safety and treatment outcomes, as well as potential impacts of the medical tourism industry on third parties. This paper explores the feedback from former Canadian medical tourists regarding the use of an information sheet to address this knowledge gap and raise awareness of the safety and ethical concerns related to medical tourism. Results According to feedback provided in interviews with former Canadian medical tourists, the majority of participants responded positively to the information sheet and indicated that this document prompted them to engage in further consideration of these issues. Participants indicated some frustration after reading the information sheet regarding a lack of know-how in terms of learning more about the concerns discussed in the document and changing their decision-making. This frustration was due to participants’ desperation for medical care, a topic which participants frequently discussed regarding ethical concerns related to health care provision. Conclusions The overall perceptions of former medical tourists indicate that an information sheet may promote further consideration of ethical concerns of medical tourism. However, given that these interviews were performed with former medical tourists, it remains unknown whether such a document might impact upon the decision-making of prospective medical tourists. Furthermore, participants indicated a need for an additional tool such as a website for continued discussion about these concerns. As such, along with dissemination of the information sheet

After receiving the chitosan sample from Prof. Dr Rosiak we started the duty of harmonization procedures for the characterization of raw materials in terms of molecular weight determination by viscosity and to proceed with the measurements of samples of alginates and carrageenans For investigation of radiation–processed alginates for agriculture applications degraded polymers were used as plant growth promoters, in different crops, such as tomato, lettuce, spinach and cabbage under different environmental conditions. By irradiation of alginates with various radiation doses (500, 750 and 1000 kGy gamma rays) degraded alginates have been obtained. They have been applied in horticultural species in 20 and 100 microgram/l concentrations, in solution state (under hydroponics cultivation condition) and by foliar spraying (under soil less culture). In a preliminary phase of this study, different alginate treatments (radiation doses and concentrations) were applied to determine the effect on seedlings quality, evaluated through leaf and root development, shoot/root ratio and photosynthetic activity. UV-vis spectroscopy of alginate irradiated at very high doses ( up to 1000 kGy) showed an abrupt change in the macroscopic shape of the sample forming hard particles and shifting the absorbing band to a higher wavelength. Alginates irradiated in solution shows an absorption band at 265 nm approximately and increases steadily with dose. Alginates irradiated in solid state shows also the absorption band at 265 and increases with doses but this band disappears at higher dose and shows a new wider band at 427 nm. Degradation was also observed accompanied by a color change to deep brown for highly degraded alginate. A conclusion

    While fruit, candy and alcohol characterising flavours are not allowed in cigarettes in the USA, other flavoured tobacco products such as smokeless tobacco (ST) continue to be sold. We investigated tobacco manufacturers' use of flavoured additives in ST products, the target audience(s) for flavoured products, and marketing strategies promoting products by emphasising their flavour. Qualitative analysis of internal tobacco industry documents triangulated with data from national newspaper articles, trade press and internet. Internally, flavoured products have been consistently associated with young and inexperienced tobacco users. Internal studies confirmed that candy-like sweeter milder flavours (eg, mint, fruit) could increase appeal to starters by evoking a perception of mildness, blinding the strong tobacco taste and unpleasant mouth feel; or by modifying nicotine delivery by affecting product pH. Similar to cigarettes, flavoured ST is likely to encourage novices to start using tobacco, and regulations limiting or eliminating flavours in cigarettes should be extended to include flavoured ST products.

    Journal Impact Factor (JIF) has been used in assessing scientific journals. Other indices, h- and g-indices and Article Influence Score (AIS), have been developed to overcome some limitations of JIF. The aims of this study were, first, to critically assess the use of JIF and other parameters related to medical education research, and second, to discuss the capacity of these indices in assessing research productivity as well as their utility in academic promotion. The JIF of 16 medical education journals from 2000 to 2011 was examined together with the research evidence about JIF in assessing research outcomes of medical educators. The findings were discussed in light of the nonnumerical criteria often used in academic promotion. In conclusion, JIF was not designed for assessing individual or group research performance, and it seems unsuitable for such purposes. Although the g- and h-indices have demonstrated promising outcomes, further developments are needed for their use as academic promotion criteria. For top academic positions, additional criteria could include leadership, evidence of international impact, and contributions to the advancement of knowledge with regard to medical education.

    In medical practice use of sterile pharmaceuticals and single use disposable medical devices is steadily increasing. Sterile pharmaceuticals like injections and ophthalmic ointments are required for therapy. Medical devices are employed for diagnostic, drug administration or corrective purposes, and as implants for temporary, short term or long term residence in the human system. All these products are made available in sterile form by treating them to a suitable process of sterilization i.e. dry/wet heat, ethylene oxide (EtO) gas or ionizing radiation. In this paper current trends and future prospects of radiation sterilization of medical products are given in detail. 9 refs., 7 tabs

    The role of production in competitive system of market on one hand and the changing conditions of market on the other hand has caused the need for more developed planning in such environments. The general purpose of the present research is to realize One-of- a- Kind- Product model (OKP) that is developed in two stages. In OKP model presented in 1994 only one sample of each product is produced and only one production method is considered for each product. In order to make OKP model more real and to use it in promoting more production methods, the following developments were made in this research: 1-First Development: Considering various methods for producing each product. 2-Second Development: Producing more than one sample of each product, while considering various production methods for each product. These models promoted OKP model of 1994. They can be used in more diversified production methods in order to promote them. In present model, while describing the main OKP model new models are provided as well. The significance of OKP has been described in Introduction

    During the 50-yr history of the use of radioisotopes for medical applications, research reactors have played a pivotal role in the production of many if not most of the key products. The marriage between research reactors and production operations is subject to significant challenges on two fronts. The medical applications of the radioisotope products impose some unique constraints and requirements on the production process. In addition, the mandates and priorities of a research reactor are not always congruent with the demands of a production environment. This paper briefly reviews the historical development of medical isotope production, identifies the unique challenges facing this endeavor, and discusses the management of the relationship between the isotope producer and the research reactor operator. Finally, the key elements of a successful relationship are identified

    This article presents an integrative review of the evidence for combined motivational interviewing and cognitive behavioural interventions that promote medication adherence. We undertook this review to establish a scientific foundation for development of interventions to promote medication adherence and to guide clinical practice. The World Health Organization has designated medication adherence as a global problem. Motivational interviewing and cognitive behaviour interventions have been found to individually promote medication adherence. However, there is a gap in the literature on the effect of combined motivational interviewing and cognitive behavioural approaches to promote medication adherence. Integrative review. COCHRANE, PubMed and CINAHL were searched to access relevant studies between 2004-2014. Inclusion criteria were interventions combining motivational interviewing and cognitive behavioural therapy with medication adherence as the outcome. Articles were assessed for measures of adherence and methodological rigour. Analysis was performed using an integrative review process. Six articles met the inclusion criteria. A randomised controlled trial reported pretreatment missed doses of 5·58 and post-treatment of 0·92 and trended towards significance. Four cohort studies had effect sizes of 0·19-0·35 (p motivational interviewing and cognitive behavioural interventions, five out of six were effective at improving medication adherence. Future studies with large rigorous randomised trials are needed. This review provides clinicians with the state of the science in relation to combined motivational interviewing and cognitive behavioural therapy interventions that promote medication adherence.

    Full Text Available The ecolabel is one of the indicators that quantify sustainable consumption and production, and ultimately, sustainable development. Ecolabelling is only one type of environmental labelling, and refers specifically to the provision of information to consumers about the relative environmental quality of a product. Ecolabels are granted on request of various organizations, both public and private, and are recognized only locally or nationally, regionally or internationally. Often coexist at the same time and same place, several types of environmental labels. The acceptance of a particular ecolabel is optional, and is made usually based on reputation, trust and awareness about the label and the level to promote certain brands for better lifestyle and for use the eco, organic or green products. There are currently tracking worldwide by Ecolabel Index, which is the largest global directory of ecolabels, 449 ecolabels in 197 countries, and 25 industry sectors, from which 109 are for textile products. The number of EU Ecolabel greatly increased, so that in the period 2000- 2010, the increase was more than 20 times. At the end of 2012, 17176 products or services was awarded EU Ecolabel. Curently, certainly, the number is much higher. Today, in the Ecolabel Index appear registered in Romania 23 types of ecolabels. Also, Romania currently has awarded 586 licenses for Eu Ecolabel, from which two for textile products and two for footwear.

    2013-01-01

    This paper describes a curricular model to support the production of quality research and development of occupational therapy professional students, prepared to become leaders in the production and utilization of evidence for practice. This model is designed for programs with faculty challenged by the dual mandate of program excellence and expectations for scholarly productivity needed for tenure and promotion: typically programs at research universities. The essence of the model is the paralleling of research and competencies for clinical practice where faculty and students participate as a community of scholars. It is based on the literature that addresses the tensions between achieving excellence in research and scholarly productivity, and excellence in teaching. The experience of one university with this model over a five-year period of time is shared with the student-faculty productivity outcomes. These outcomes include dissemination of 55 collaborative peer reviewed products and faculty has generated support for 25 paid graduate assistantships. The combination of student outcomes and faculty support for their research has strengthened the ability of the faculty to excel in meeting the University mandate of scholarship while providing a high quality professional educational program.

    An important product among the radiopharmaceuticals currently used in cardiology is T1 201 chloride, due to its nuclear-physical properties and its clinical value as a diagnostic tool. The authors explain and discuss the basic characteristics which determine the radiopharmaceutical quality of T1 201: its radiochemical purity and its chemical impurity content, which depend on the target-irradiation conditions - type of nuclear reaction, target material and design, particle energy, irradiation time - and the reprocessing technology. A production flow chart is presented which shows that ions are accelerated within a wide mass and energy range suitable for the production of T1 201 in different nuclear reactions. Cyclotron reconstruction for T1 201 production is discussed

    The prophecy of health promoting hospitals (HPH) is bringing about a change and transition from treatment-oriented to health-oriented attitudes. In Iran, hospitals usually play the traditional roles. The present study was aimed at the evaluation of the health promotion status in specialized hospitals associated with Hamadan University of Medical Sciences (HUMS). This applied study was conducted in two Hamadan specialized hospitals in the Hamadan city. The health promotion status was evaluated using a self-assessment checklist designed by the World Health Organization's HPH. The evaluation was done in five standards including management policy, patient assessment, patient information and intervention, promotion of a healthy workplace and continuity and cooperation. The results showed that both the hospitals studied had a poor status in terms of promoting a healthy workplace (average = 31.24%) and management policy standards (average = 35.29%) in comparison with the other relevant standards: patient assessment (53.12%), patient information and intervention (62.5%), continuity and cooperation (65.78%)). The results of the standards and sub-standards status displayed better performance in the cardiovascular hospital (53.67%) compared to the women and parturition hospital (42.64%). The findings indicated that HPH standards are very low in the studied hospitals. The reason behind this wide gap might be due to the fact that hospitals in Iran are more treatment-oriented and patient-oriented and they do not play an active part in health promoting. It was found that management policy and promoting healthy workplace standards had the worst status and must be improved.

    1993-05-01

    We start with a short introduction about the concept of "bad promotional practices" within the Pharmaceutical Industry's (PHI) communication, giving rise to the birth of so-called "un-representatives" (un'rep). Taking the self-control model from the "Association of the British Pharmaceutical Industry" (ABPI), based upon the "code of practice" as a paradigma, we comment about those who notify presumed code's breaches besides the assessment process and penalties that are usually imposed. We also considered the possibility that sometimes the physician instead of being a prosecutor is accused, by the PHI, of supposed "Medical Deonthological Code's" Infringement. The several modalities of malpraxis during the un-rep visit are classified into four categories: product un-information; unloyal competition; echonomical temptations addressed toward physicians; and disregarding stablished visit planning. We devote most of the text to exemplarize five common and very well documented situations; promotion of non-registered indications; influence of prescriptions through prebends to doctors; doubtful payments to compensate clinical trials and drug surveillance studies; the use of exagerated claims; and the abuse of the qualification "drug of choice". We end with a self-critism, from the phi's outlook on the prudence that a "good pharmaceutical communicator" must respect. As an excellent model of wisdom, we propose doctors, Because they follow the classical good-sense picture that illustrates the process of adoption of a new drug. We emphasize the fact that product over-estimation, creating false expectatives, is--together with the lak of informative liability--one of major reasons for a drug innovation to fail.

    Full Text Available In this work, an attempt is made to use the terminology and tools of the economy of experience as applied to the hotel product. The analysis of the concept of "economy of experience" is analyzed from the point of view of changing human preferences and the appearance of the so-called "market ofexperience". The postulate is advanced that in the modern economy the sale of any goods and services corresponds with the sale of the corresponding impressions from using them, therefore the most successful business projects are aimed not only at satisfying physiological needs, impressions. The object of exchange is not only goods and services, but also impressions, respectively, the emergence of a new exchange object calls for the development of technologies that make this object more attractive to the direct consumer and show the manufacturer what benefits it can receive from the production and sale of impressions. An attempt has been made to transfer the tools of the economy of impressions to the area of promotion of the hotel product. The hotel economy is a dynamically developing branch of the economy, its development is determined by global economic processes, cultural, historical, sport interactions both within the country and between countries. Along with tourism, the hotel industry is an integral part of the creative economy and the economy of experience, which is based on the desires and needs of a person in gaining new experience. Practice shows that the use of tools in the promotion of the hotel product that affect the receipt of new impressions, feelings and experiences creates a basis for attracting regular customers, on which 60% of the income of the hotel company depends.

    Full text: In connection with intensive development of pharmacology and medical techniques, use of the products contacting to blood, with the internal environment of an organism, with wound surface, with mucous membranes and skin there were high requirements to sterility of pharmaceutical preparations and medical products. Traditional methods of sterilization (heat treatment, gas processing and processing the ferry) have some restrictions in application, and not insufficient degree of sterilization required for pharmaceutical preparations and medical products. Thermal processing can lead to degradation of structure (medicine), mechanical changes and loss of medical properties. Besides, it is impossible to carry out sterilization of many pharmaceutical preparations by a method of heat treatment. Sterilization of products in packing is very complicated, because sterilization temperature of packing and a product is different. Gas processing is basically applied to sterilization of medical products (syringes, bandage, cotton wools, etc.). However, the degree of sterility is low, because of rather low ability and heterogeneity of sterilizing substance. Sterilization in packing represents special difficulty and demands additional charges related with delivery of the purified gas from abroad. Last years alongside with known technological methods of sterilization of medical products and pharmaceutical preparations radiating methods of processing have found wide application. Use of electronic bunches with the moderate energy and various isotopes became a basis for formation and development of a new direction in the medicine, called by 'radiation sterilization'. The radiation technology is highly harmless and economic, not polluting substance and surrounding space. Unlike the specified traditional methods, radiating processing of products by the isotope 60 Co, radiating the gamma quantum, has unique opportunities - high penetrability in substance, providing uniformity of

    The function of medical school entities that determine student advancement or dismissal has gone largely unexplored. The decision making of 'academic progress' or student promotions committees is examined using a theoretical framework contrasting ethics of justice and care, with roots in the moral development work of theorists Kohlberg and Gilligan. To ascertain promotions committee members' conceptualisation of the role of their committee, ethical orientations used in member decision making, and student characteristics most influential in that decision making. An electronic survey was distributed to voting members of promotions committees at 143 accredited allopathic medical schools in the USA. Descriptive statistics were calculated and data were analysed by gender, role, institution type and class size. Respondents included 241 voting members of promotions committees at 55 medical schools. Respondents endorsed various promotions committee roles, including acting in the best interest of learners' future patients and graduating highly qualified learners. Implementing policy was assigned lower importance. The overall pattern of responses did not indicate a predominant orientation toward an ethic of justice or care. Respondents indicated that committees have discretion to take individual student characteristics into consideration during deliberations, and that they do so in practice. Among the student characteristics with the greatest influence on decision making, professionalism and academic performance were paramount. Eighty-five per cent of participants indicated that they received no training. Promotions committee members do not regard orientations of justice and care as being mutually exclusive and endorse an array of statements regarding the committee's purpose that may conflict with one another. The considerable variance in the influence of student characteristics and the general absence of committee member training indicate a need for clear delineation of the

    The Galilee Medical Center (GMC) is unique in several aspects. Firstly, in the clinical aspect: In recent years, led by the Director of Medical Center, Dr. Masad Barhoum, a considerable momentum of development has taken place to reduce health discrepancies between the center and the periphery. Despite the under- financing of the health system in the Galilee, the GMC opened new clinical departments, introduced advanced medical technology and key staff members were added. This approach is depicted in publications presented in the current issue. Secondly, the aspect of medicine standoff: The GMC is the nearest hospital to the border with neighboring countries. It is also a tertiary center for trauma, due to the establishment of the Department of Neurosurgery, Department of Oral and Maxillofacial Surgery and the Departments of Orthopedic Surgery, general invasive radiology and invasive radiology of the brain. In recent years, the medical center treated hundreds of victims of the civil war in Syria, a third of them - women and children. The injured patients presented unique medical problems that are described in the papers in this issue. Thirdly, the research aspect: The medical center is the main teaching facility of medical students of the Faculty of Medicine in the Galilee of Bar-Ilan University. The Faculty of Medicine, led by the Dean, Prof. Ran Tur-Kaspa, promotes research and teaching in the medical center. Even before the establishment of the Faculty of Medicine, former hospital director, Prof. Shaul Shasha, not only extolled the importance of research, but established a research laboratory years ago. The laboratory continues to pursue translational research by the physicians of the medical center, led by Dr. Shifra Sela and Prof. Batya Kristal, and supported by the current medical center director, Dr. Masad Barhoum. Several studies conducted in this research laboratory are published herewith. With these unique aspects and despite the discrimination in funding

    The Australian government, through its instrumentality, the Australian Nuclear Science and Technology Organization (ANSTO), owns and operates a 10-MW Dido-class research reactor at Lucas Heights on the southern outskirts of Sydney. This is the only operating nuclear reactor in Australia. It was built in 1958 and has a maximum flux of 1 x 10{sup 14} n/cm{sup 2}{center_dot}s. ANSTO also jointly owns and operates a 30-MeV IBA negative ion cyclotron at Camperdown in central Sydney, which began operation in 1992. ANSTO is predominantly a research organization; however, radioisotopes are commercially produced through Australian Radioisotopes (ARI), an ANSTO business entity. Seventy-four people are employed by ARI, which is a vertically integrated organization, i.e., everything from target preparation to sale of products is undertaken.

    Full Text Available The organizations face to a lack of information for the development and adoption of effective management decisions in modern competitive circumstances. The organizations often use the tools of prediction for elimination of basis business data insufficiency. A high degree of reliability and accuracy of these predictions are based on the process development’s specific patterns knowledge. The purpose of this article is the analysis of rebranding as one of the patterns of product brand promotion. The article exposes such concepts as a product life cycle and brand life cycle. Also authors describe different approaches to the concepts understanding. This article identifies the relationship between these concepts and basis stages of the product life cycle and brand life cycle. The authors paid special attention on the analysis of the concept of pattern. Authors come to the conclusion that the rebranding as pattern bases on objective law of cyclicality  economic development and lead to the resumption of brand life cycle on a higher level.

    2013-01-01

    Abnormal deposition of neuriticplaques is the uniqueneuropathological hallmark of Alzheimer’s disease (AD).Amyloid β protein (Aβ), the major component of plaques, is generated from sequential cleavage of amyloidβ precursor protein (APP) by β-secretase and γ-secretase complex. Patients with diabetes mellitus (DM), characterized by chronic hyperglycemia,have increased risk of AD development.However, the role of high blood glucose in APP processing and Aβ generation remains elusive. In this study, we investigated the effect of high glucose on APP metabolism and Aβ generation in cultured human cells. We found that high glucose treatment significantly increased APP protein level in both neuronal-like and non-neuronal cells, and promoted Aβ generation. Furthermore, we found that high glucose-induced increase of APP level was not due to enhancement of APP gene transcription but resulted from inhibition of APP protein degradation. Taken together, our data indicated that hyperglycemia could promote AD pathogenesis by inhibiting APP degradation and enhancing Aβ production. More importantly, the elevation of APP level and Aβ generation by high glucose was caused by reduction of APP turnover rate.Thus,our study provides a molecular mechanism of increased risk of developing AD in patients withDMand suggests thatglycemic control might be potentially beneficial for reducing the incidence of AD in diabetic patients and delaying the AD progression.

    The key aim of this study is to evaluate the product efficiency of current hybrid vehicles and suggest effective policies to promote hybrid vehicles in the Korean automobile market and development trends of hybrid vehicles. The efficiency levels for car models sold in Korea, including hybrid ones, were measured using the recently developed discrete additive data envelopment analysis (DEA) model that reflects consumer preference. The result of the analysis shows that current hybrid vehicles on the market are still at lower competitive advantage than traditional car models with conventional combustion engines and we can suggest a mix of incentive policies to promote the competitiveness of hybrid vehicles. In addition, we also identify two distinctive trends of hybrid vehicle development: environment-oriented hybrid vehicles and performance-oriented hybrid vehicles. It implies that the government should take account of development trends of hybrid vehicles to achieve the policy goals in designing support schemes and automobile companies that are willing to develop hybrid vehicles can also gain some insights for making strategic decisions.

    Evidence-based medicine (EBM) is well known in medical practice. Although health promotion (HP) is promoted worldwide, there is still some debate as to whether EBM is needed or useful in the teaching of health promotion. To assess the perceived usefulness of EBM in the teaching of HP among medical students and faculty members. A comparative study was conducted between two groups of fourth-year medical students in the academic year 2012 during the five-week Health Promotion Teaching Block at Prince of Songkla University, southern Thailand. A one-week EBM course was conducted with half the students in the first week of the block and the other half of the students in the last week of the block. All activities in the HP block were similar except for the different periods of the one-week of EBM teaching. The effect on knowledge, ability and perceived application of EBM in future practice was assessed by student self-evaluations before versus after taking the EBM course, and by faculty member evaluation of the students' end-of-block presentations. All evaluation items were rated from 1 (lowest) to 5 (highest). Data were analyzed using a t-test or Wilcoxon test, as appropriate. The students' self-evaluations of knowledge and ability on EBM between the two groups were similar. The perception that teaching EBM is beneficial in health promotion and future practice increased significantly ( phigher scores for the first group than the second group, although the rating differences were not at the level of significance. Ninety percent of the students believed that EBM was a useful addition to the teaching of HP. Medical students and faculty members perceived that EBM is useful in the HP context. Future studies to evaluate the effect of using evidence-based teaching for health promotion are needed.

    Which are the differences in health-related quality of life and stress management in medical and dental students? 101 dental and 237 medical students from different years of Justus-Liebig University Giessen were examined during winter term 2008/09 and summer term 2009 using the specific Questionnaire on Health Promotion, Life Satisfaction, and Stress Management in Dental or Medical Students (addressing work satisfaction and choice of subject, private life, relaxation behavior and stress management, and health behavior), Beck Depression Inventory (BDI) and SF-36 Health Survey. For statistical analysis, Mann-Whitney-U-Test, analysis of variance (ANOVA), Pearson correlation and Chi2-Tests were primarily used. Dental and medical students showed considerable mental impairment in SF-36. Every fifth dental student suffered from slight to moderate depression. Though averaging more hours per week, medical students were more satisfied with their studies. More than half of the dental and medical students did not have appropriate strategies of coping with stress. Concerning the mental impairment in both groups and regarding a higher health-related quality of life, specific prevention courses or mentoring programs should already be offered at the beginning of medical training in order to cope with strains of medical school and future job strains in the medical or dental profession. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available The popularity of products depends not only on its quality, but also on the activities that have been undertaken to promote it in the market. The media plan developed for this purpose should be based on the use of scientific approaches, since the success of an advertising campaign directly depends on the correctness of the selected promotion channels and the level of the developed advertising and information materials. At the same time, it is necessary to optimize the media plan, which makes it possible to ensure the effectiveness of advertising by attracting consumers, advancing competitors and rational use of resources, including material ones. The article gives an example of a developed advertising campaign for the promotion of bakery products: advertising channels in magazines, a radio commercial in shopping centers, advertising stand and distribution of flyers were chosen as channels for promotion. The general concept of this advertising is the promotion of various types of fresh hot products, so the main character is Red Riding Hood. The article gives examples of layouts of printed materials, an approximate scenario of a radio commercial and a description of the layout of magazine advertising. To assess the adequacy of the developed advertising company, the media plan and expenses for creating and conducting an advertising campaign are calculated.. On its basis, a methodology is formulated and an algorithm for performing these marketing activities is constructed. An important step in the application of this technique is its standardization - the creation of an organization standard. The standardization document containing the rules, regulations and requirements will allow optimizing production processes and increasing the competitiveness of the enterprise's products, and also contributes to a common understanding of marketing concepts and advertising policy in the enterprise.

    Full Text Available Abstract Plant growth-promoting rhizobacteria strains from special formulations have been used to optimize eucalyptus cutting production. To undertake quality control for the formulated products, the rhizobacterial strains should be characterized to assess their purity and authentication. In the present study, we characterized nine strains of rhizobacteria, including three Bacillus subtilis (S1, S2 and 3918, two Pseudomonas sp. (MF4 and FL2, P. putida (MF2, P. fulva (Ca, Frateuria aurantia (R1, and Stenotrophomonas maltophilia (CIIb. The strains were differentiated by colony morphology after 24 h of incubation in three different solid state culture media (glucose-nutritive agar, 523 medium and yeast extract-mannitol agar, sensitivity to a panel of 28 antibiotics (expressed according to the formation of inhibition halos of bacterial growth in the presence of antibiotics, and PCR-RFLP profiles of the 16S rDNA gene produced using nine restriction enzymes. It was possible to differentiate all nine strains of rhizobacteria using their morphological characteristics and sensitivity to antibiotics. The molecular analysis allowed us to separate the strains CIIb, FL2 and R1 from the strains belonging to the genera Bacillus and Pseudomonas. By using these three methods concomitantly, we were able to determine strain purity and perform the authentication.

  7. A proposed standard on medical isotope production in fission reactors

    Schenter, R. E.; Brown, G. J.; Holden, C. S.

    2006-01-01

    Authors Robert E. Sehenter, Garry Brown and Charles S. Holden argue that a Standard for 'Medical Isotope Production' is needed. Medical isotopes are becoming major components of application for the diagnosis and treatment of all the major diseases including all forms of cancer, heart disease, arthritis, Alzheimer's, among others. Current nuclear data to perform calculations is incomplete, dated or imprecise or otherwise flawed for many isotopes that could have significant applications in medicine. Improved data files will assist computational analyses to design means and methods for improved isotope production techniques in the fission reactor systems. Initial focus of the Standard is expected to be on neutron cross section and branching data for both fast and thermal reactor systems. Evaluated and reviewed tables giving thermal capture cross sections and resonance integrals for the major target and product medical isotopes would be the expected 'first start' for the 'Standard Working Group'.

    The practice of medical tourism depends on successfully informing potential patients about procedure options, treatment facilities, tourism opportunities, travel arrangements, and destination countries. The promotion of medical tourism includes a wide range of marketing materials such as flyers, booklets, and websites. Yet, there is a paucity of knowledge about the dissemination, content, and reception of these promotional materials. Drawing on a thematic content analysis of the promotional print material distributed at the first medical tourism trade show in Canada in 2009, the main purpose of this article is to identify and understand the messages and images that companies use to market India as a global destination. While researchers and news media frequently cite low cost procedures as a key determinant for international patient travel, particularly to developing nations, our analysis reveals few low cost-related images or messages in the promotional materials distributed at the trade show. To help explain this surprising disjuncture, we consider four related issues: (1) promotional materials may be designed to be circulated amongst potential patients' concerned family and friends who privilege knowing about things such as the use of advanced technologies; (2) developing nations need to portray safe and advanced treatment facilities in order to dispel potential patients' suspicions that their medical care is inferior; (3) companies may avoid making cost saving claims that cannot be fulfilled for all of their international patients, especially those traveling from developing nations; and (4) messages of low cost may detract from and even undermine messages about quality. We conclude by identifying numerous avenues for future research by social and health scientists, and by considering the implications of our findings for existing knowledge gaps and debates within health geography specifically.

    Mammography and Pap smear tests are known to be effective early detection measures for breast and cervical cancers, respectively, but Asian Americans are reluctant to make visits for routine preventive care. Quantitative and qualitative research conducted by the Healthy Asian Americans Project (HAAP) between 1996 and 1999 indicated that Asian residents in southeastern Michigan, like the general Asian population in the US, underutilized early cancer screening programs due to cultural, psychosocial, linguistic, and economic barriers. This article reports how the HAAP's research findings guided the Michigan Breast and Cervical Cancer Control Program (BCCCP) promotion (conducted from 2000 to 2001 among medically underserved Asian women residing in southeastern Michigan), and how evaluation of the HAAP's BCCCP promotion will direct future research and health promotion programs. The article presents strategies used to improve access to cancer screening programs for diverse Asian sub-groups as well as outcomes of the 2-year HAAP's BCCCP promotion among the target population. Discussion regarding lessons and experiences gained from integration of research and practice has implications on design and implementation of the cancer screening promotion for the rapidly increasing Asian American population as well as other medically underserved minority populations in the US.

    Most educational institutions lack a structured system that provides undergraduate students with research exposure in the medical field. The objective of this paper is to describe the structure of the Medical Research Volunteer Program (MRVP) which was established at the American University of Beirut, Lebanon, as well as to assess the success of the program. The MRVP is a program that targets undergraduate students interested in becoming involved in the medical research field early on in their academic career. It provides students with an active experience and the opportunity to learn from and support physicians, clinical researchers, basic science researchers and other health professionals. Through this program, students are assigned to researchers and become part of a research team where they observe and aid on a volunteer basis. This paper presents the MRVP's four major pillars: the students, the faculty members, the MRVP committee, and the online portal. Moreover, details of the MRVP process are provided. The success of the program was assessed by carrying out analyses using information gathered from the MRVP participants (both students and faculty). Satisfaction with the program was assessed using a set of questions rated on a Likert scale, ranging from 1 (lowest satisfaction) to 5 (highest satisfaction). A total of 211 students applied to the program with a total of 164 matches being completed. Since the beginning of the program, three students have each co-authored a publication in peer-reviewed journals with their respective faculty members. The majority of the students rated the program positively. Of the total number of students who completed the program period, 35.1 % rated the effectiveness of the program with a 5, 54.8 % rated 4, and 8.6 % rated 3. A small number of students gave lower ratings of 2 and 1 (1.1 % and 0.4 %, respectively). The MRVP is a program that provides undergraduate students with the opportunity to learn about research firsthand

    Full Text Available Objective: To promote first year (P1 pharmacy students’ awareness of medication error prevention and to support student learning in biomedical and pharmaceutical sciences. Innovation: A novel curricular activity was created and referred to as “Medication Errors and Sciences Applications (MESA”. The MESA activity encouraged discussions of patient safety among students and faculty to link medication errors to biomedical and pharmaceutical sciences, which ultimately reinforced student learning in P1 curricular topics.   Critical Analysis: Three P1 cohorts implemented the MESA activity and approximately 75% of students from each cohort completed a reliable assessment instrument. Each P1 cohort had at least 14 student teams who generated professional reports analyzing authentic medication errors. The quantitative assessment results indicated that 70-85% of students believed that the MESA activity improved student learning in biomedical and pharmaceutical sciences. More than 95% of students agreed that the MESA activity introduced them to medication errors. Approximately 90% of students agreed that the MESA activity integrated the knowledge and skills they developed through the P1 curriculum, promoted active learning and critical thinking, and encouraged students to be self-directed learners. Furthermore, our data indicated that approximately 90% of students stated that the achievement of Bloom’s taxonomy's six learning objectives was promoted by completing the MESA activity. Next Steps: Pharmacy students’ awareness of medication errors is a critical component of pharmacy education, which pharmacy educators can integrate with biomedical and pharmaceutical sciences to enhance student learning in the P1 year.

    Worldwide medical device embedded software certification practices are currently focused on manufacturing best practices. In Brazil, the national regulatory agency does not hold a local certification process for software-intensive medical devices and admits international certification (e.g. FDA and CE) from local and international industry to operate in the Brazilian health care market. We present here a product-based certification process as a candidate process to support the Brazilian regulatory agency ANVISA in medical device software regulation. Center of Strategic Technology for Healthcare (NUTES) medical device embedded software certification is based on a solid safety quality model and has been tested with reasonable success against the Class I risk device Generic Infusion Pump (GIP).

  16. Medical-isotope supply hit by production problems

    Science.gov (United States)

    Gould, Paula

    2008-10-01

    A shortfall in the production of medical isotopes in Europe has forced hospitals to delay patient scans or offer alternative diagnostic tests. The problems began in August when all three nuclear reactors used to generate molybdenum-99, which then decays to form the key nuclear-imaging agent technetium-99, had to be unexpectedly shut down at the same time.

  17. Health promotion in medical education: lessons from a major undergraduate curriculum implementation.

    2017-11-01

    Despite the economic, environmental and patient-related imperatives to prepare medical students to become health promoting doctors, health promotion remains relatively deprioritised in medical curricula. This paper uses an in-depth case study of a health promotion curriculum implementation at a large UK medical school to provide insights into the experiences of teachers and learners across a range of topics, pedagogies, and teaching & assessment modalities. Topics included smoking cessation, behavioural change approaches to obesity, exercise prescribing, social prescribing, maternal and child health, public and global health; with pedagogies ranging from e-learning to practice-based project work. Qualitative methods including focus groups, analysis of reflective learning submissions, and evaluation data are used to illuminate motivations, frustrations, practicalities, successes and limiting factors. Over this three year implementation, a range of challenges have been highlighted including: how adequately to prepare and support clinical teachers; the need to establish relevance and importance to strategic learners; the need for experiential learning in clinical environments to support classroom-based activities; and the need to rebalance competing aspects of the curriculum. Conclusions are drawn about heterogeneous deep learning over standardised surface learning, and the impacts, both positive and negative, of different assessment modalities on these types of learning.

  20. Medical uses of radioactive calcium. Review of an IAEA programme to promote the applications of calcium-47

    International Nuclear Information System (INIS)

    1963-01-01

    Calcium plays a number of biologically essential roles, which have long been under investigation by various techniques available to medical science. One of the most important of these techniques is radioactive tracer analysis, i. e. study of the functions of calcium within the body with the help of a radioactive isotope of the element. The calcium-47 programme of the International Atomic Energy Agency is intended to promote these investigations by facilitating the production and use of this isotope. The importance attached to calcium- 47 is due to the special properties of this isotope, which make it the most valuable tool for many calcium studies by the radioactive tracer method. The Agency has for four years been engaged in a comprehensive effort to bring calcium- 47 into routine medical use. To this end, it has surveyed the need for this isotope, stimulated its cheaper production, encouraged the investigation of its medical possibilities, and arranged for the dissemination of the information thus obtained. The fact that calcium-47 is no longer considered an exotic isotope is at least partly due to the Agency's efforts, in co-operation with interested scientists throughout the world

    Annual demand for radiopharmaceuticals in Ukraine is about 50.000 GBq and expenses for their purchase are about 1 - 2 mln US dollars per year. It determines expediency of their production in Ukraine. Taking into consideration the fact that one of the aftereffects of the accident at Chernobyl Atomic Power Station is inevitable increase of the number of oncological diseases (including malignant growths of the thyroid gland) the demand for radionuclides will be increasing steadily. Therefore, it is clear that organization of the centre for radiopharmaceuticals production will not solve the problem of providing radiological departments with them. One of the possible ways to solve the problem is creation of a network of regional centres for radioactive isotopes production. Realisation of the suggested program will allow to solve the problem of providing the medical establishments of Ukraine with medical radionuclides. Performed technical and economical evaluation shows that the expenses will be compensated in 2.9 years

  2. Hydrogenation of intermediate products of furfural production at promoted nickel catalyzers

    Energy Technology Data Exchange (ETDEWEB)

    Beysekov, T.

    1980-01-01

    Examines activity of Ni-Al-Fe acids with additives Ti and W, as well as those promoted with chrome Nio-Al-Ti acids for a hydrogenation reaction of fufural condensate and raw material invarious conditions of production. It was shown that four-component acids demonstrate high activity and selectivity in tetrahydrofuryl alcohol. Hydrogenation rate of furfural condensate on more active compounds of acids is by 1.2-1.4 times higher than in non-promoted with the fourth component of acid. The promoting effect of fourth components, based on data of phase-structural analysis, is explained by changes in the number of correlations of known phases and eutectics, and formation of new presently undeciphered intermetallides, the destruction of which aids, apparently, in the formation of qualitatively new active centers on the surface. It was established that stationary acids also have high activity and stability. Changing leaching depths, H/sub 2/ pressure, temperature, rate of H/sub 2/ bubbling has a favorable effect on the end product.

    Full Text Available Abstract Background Prior literature has shown that physicians with healthy personal habits are more likely to encourage patients to adopt similar habits. However, despite the possibility that promoting medical student health might therefore efficiently improve patient outcomes, no one has studied whether such promotion happens in medical school. We therefore wished to describe both typical and outstanding personal health promotion environments experienced by students in U.S. medical schools. Methods We collected information through four different modalities: a literature review, written surveys of medical school deans and students, student and dean focus groups, and site visits at and interviews with medical schools with reportedly outstanding student health promotion programs. Results We found strong correlations between deans' and students' perceptions of their schools' health promotion environments, including consistent support of the idea of schools' encouraging healthy student behaviors, with less consistent follow-through by schools on this concept. Though students seemed to have thought little about the relationships between their own personal and clinical health promotion practices, deans felt strongly that faculty members should model healthy behaviors. Conclusions Deans' support of the relationship between physicians' personal and clinical health practices, and concern about their institutions' acting on this relationship augurs well for the role of student health promotion in the future of medical education. Deans seem to understand their students' health environment, and believe it could and should be improved; if this is acted on, it could create important positive changes in medical education and in disease prevention.

  5. Prospects for radiation sterilization of medical products in Egypt

    Roushdy, H.M.

    1975-01-01

    The pharmaceutical industry in Egypt is continually expanding its activity and each year marks new accomplishments and additions which enable the companies to apply the most modern scientific means in the production of pharmaceutical preparations and consequently to improve their market potentialities. The certainty of expansion and the possibility of increasing exports of sterilized medical products, particularly to Arab and African countries, indicate a need for a gamma-sterilization plant. This technology permits the introduction of the latest practices with regard to used disposables, thus greatly reducing the chances of cross-contamination which usually results in serious complications enhanced by local environmental conditions. This paper reviews the current state and future prospects for radiation sterilization of medical products and biological tissues in connection with other related industrial radiation processings. Moreover, the paper reviews the Egyptian scientific and technical experience with irradiation facilities and the parameters underlying the choice of Egypt's first industrial gamma and electron-beam irradiators designed for more than a single-purpose use, with hygienic measures taken to avoid biological contamination of sterilized medical packages throughout the sterilization process. In addition, the paper deals with the policy set up for establishing the Egyptian National Centre for Radiation Technology with a view to introducing irradiation techniques in the sterilization of medical products, and to improving the properties and increasing the competitiveness of Egyptian fabrics. Apart from medical sterilization, certain industrial processes have been mentioned to show how a multi-purpose irradiation facility may be utilized in a developing country to justify significantly the large investment required.

    2001-01-01

    This report was prepared by the Center for Disease Prevention and Health Promotion in the Institute for Health and Productivity Management as part of an effort to improve understanding of the connection between employee health and performance and to begin to identify new strategies through which treating health as an investment in human capital can lead to greater business success. Computer database searches of peer-reviewed literature published between 1993 and 1998 and manual reviews of 20 journals were used to identify research on the link between employee health and performance. Data was extracted to summarize the overall findings on the magnitude of health problems addressed by health promotion and disease prevention programs, and the impact of interventions on improving health risk, reducing medical care cost, and improving worker performance. From this summary, major conclusions on early detection of disease, the impact of behavior change programs, and appropriate care-seeking were drawn. This systematic review is supplemented with summaries of 15 seminal articles and descriptions of five leading-practices programs. The influence of developments in work/family issues, complementary and alternative medicine, and quality of care and health outcomes research are briefly discussed. Finally, a conceptual framework for studying the impact of health and productivity is described.

    1985-01-01

    The production of radionuclides for medical and biomedical research in Canada has been reviewed with respect to the national geographic and demographic characteristics which influence their use. The types of facilities available for the production of short-lived radionuclides have been summarized, and a tabulation of the radionuclides that are produced has been presented. In broad terms production facilities can be classified as belonging to one of two groups, nuclear reactor or charged-particle accelerators. The charged-particle accelerators produce the more neutron-deficient and (because of the resultant decay properties) the more useful radionuclides for medical application. The nuclear reactor facilities for radionuclide production range in size and capacity from the high-flux research reactors of AECL to the six SLOWPOKE reactors, five of which are located on university campuses across the country. The McMaster University reactor is used to produce curie quantities of fluorine-18 weekly. Millicurie amounts of a large number of radionuclides, most of which have half-lives ranging from 2 to 50 hr, are produced in the low-flux reactors, in support of basic medical research

    Singson, C.; Carmona, C.; de Guzman, Z.; Barrun, W.; Lanuza, L.

    This paper presents the results of a comprehensive investigation of the biological, microbiological, physico-chemical, and dosimetry aspects of using gamma irradiation for the sterilization of locally manufactured medical products and pharmaceuticals. The objective of this study is to determine the technological feasibility of radiation sterilization for the said products in the Philippines. Hence, the materials used were directly obtained from local manufacturers. They are polyvinyl chloride or polyethylene based medical plastic disposables namely: absorbent cotton, surgical gauze, bandage, visceral packs, and some antibiotics and opthalmic ointments. The gamma facility of the Philippine Atomic Energy Commission was used for the irradiation. Result of biological studies indicate no signs of toxicity on experimental mice injected with extracts from irradiated samples. The contaminants are identified as Pseudomonas Sp. Staphyloccocus Aureus and Bacillus Subtilis. The D 10 values of survivors of higher doses ranged below 0.235 Megarad suggesting that these contaminants can be eliminated by the generally used sterilizing dose of 2.5 Mrads. The physico-chemical tests did not indicate any significant degradation of the irradiated products. Opthalmic and topical antibiotic ointments showed no marked decrease in potency. Fading tests on dosimeters used showed that red perspex is a more efficient dosimeter than clear perspex when irradiation time is prolonged. These studies indicated that radiation sterilization is technically feasible for locally manufactured medical products.

    2011-04-01

    To estimate the relationship between electronic medical record (EMR) use and efficiency of utilization and provider productivity during visits to US office-based physicians. Cross-sectional analysis of the 2006-2007 National Ambulatory Medical Care Survey. The sample included 62,710 patient visits to 2625 physicians. EMR systems included demographics, clinical notes, prescription orders, and laboratory and imaging results. Efficiency was measured as utilization of examinations, laboratory tests, radiology procedures, health education, nonmedication treatments, and medications. Productivity was measured as total services provided per 20-minute period. Survey-weighted regressions estimated association of EMR use with services provided, visit intensity/duration, and productivity. Marginal effects were estimated by averaging across all visits and by major reason for visit. EMR use was associated with higher probability of any examination (7.7%, 95% confidence interval [CI] = 2.4%, 13.1%); any laboratory test (5.7%, 95% CI = 2.6%, 8.8%); any health education (4.9%, 95% CI = 0.2%, 9.6%); and fewer laboratory tests (-7.1%, 95% CI = -14.2%, -0.1%). During pre/post surgery visits, EMR use was associated with 7.3% (95% CI= -12.9%, -1.8%) fewer radiology procedures. EMR use was not associated with utilization of nonmedication treatments and medications, or visit duration. During routine visits for a chronic problem, EMR use was associated with 11.2% (95% CI = 5.7%, 16.8%) more diagnostic/screening services provided per 20-minute period. EMR use had a mixed association with efficiency and productivity during office visits. EMRs may improve provider productivity, especially during visits for a new problem and routine chronic care.

    2017-01-01

    Full Text Available Background: Drug promotional literature (DPLs is an integral part of pharmaceutical marketing strategy. This marketing approach influences, a physician to prescribe definite variety of medicine from a particular company. Many physicians bank on exclusively in DPLs. This research was intended to appraise the DPLs available in Bangladesh for accuracy, consistency, and validity of the information in accordance with the WHO rules and regulations. Materials and Methods: This was a cross-sectional study was conducted in Uttara Adhunik Medical College, Dhaka, Bangladesh after collecting DPLs from the different outpatient department. The data was analyzed Microsoft Excel 2016. Results: None of the national and multinational DPLs fulfilled all the WHO criteria. Among the national and multinational DPLs, 94.7% and 100% presented with claims respectively. Out of 284 national and multinational DPLs references citation were presented in 82.04% and 100% respectively. Among the DPLs of national and multinational companies' relevant, irrelevant, and partially relevant pictures were presented in 48.79%, 24.65%, 26.76% and 31.58%, 26.32%, and 42.11%, respectively. Conclusion: DPLs of Bangladesh did not comply with the WHO guidelines while promoting their products. Evidence provided in those DPLs were mostly biased and persuasive since it is focusing mainly on the positive aspect of drug therapy. Accordingly, studied DPLs were principally aiming to maximizes industries' financial benefit rather than fulfill the educational aspects. The Government of Bangladesh should develop very stringent policy and practices regarding DPLs based on science and the WHO guideline as the literature very often act as a primary source of information among medical doctors.

    Advances in technology and decreasing costs have led to an increased use of unmanned aerial vehicles (UAVs) by the military and civilian sectors. The use of UAVs in commerce is restricted by US Federal Aviation Administration (FAA) regulations, but the FAA is drafting new regulations that are expected to expand commercial applications. Currently, the transportation of medical goods in times of critical need is limited to wheeled motor vehicles and manned aircraft, options that can be costly and slow. This article explores the demand for, feasibility of, and risks associated with the use of UAVs to deliver medical products, including blood derivatives and pharmaceuticals, to hospitals, mass casualty scenes, and offshore vessels in times of critical demand.

    Objective To investigate the role of bromodomain containing 3 (Brd3) in LPS-triggered interleukin-6 (IL-6) production in macrophages and the underlying mechanism. Methods CRISPR-Cas9 technology was used to screen an RAW264.7 cell line with Brd3 knockout (Brd3 -/- ). The Brd3 -/- cells were used as an experimental group, and the parential cells expressing wide-type Brd3 as a control group. The IL-6 level in cell culture supernatant was detected by ELISA after 100 ng/mL LPS challenging. Effect of Brd3 knockout on the expression and activation of signal pathways involved in IL-6 expression, including the NF-κB and mitogen-activated protein kinase (MAPK) pathways were examined by Western blot analysis. Chromatin immunoprecipitation (ChIP) assay was used to evaluate the recruitment of acetylase CREB-binding protein (CBP) to IL6 gene promoter and the acetylation level of histone 3 within IL6 gene promoter. Results LPS treatment significantly downregulated Brd3 expression in mouse peritoneal macrophages. LPS-induced production of IL-6 was significantly inhibited in Brd3 -/- macrophages. The expressions and activation of signal molecules within NF-κB and MAPK pathways were barely affected. Brd3 knockout significantly decreased the recruitment of acetylase CBP to IL6 gene promoter, and the acetylation level of histone3 within IL6 gene promoter was also repressed. Conclusion Brd3 promotes LPS-triggered IL-6 production via promoting the recruitment of CBP to IL6 promoter and enhancing the acetylation level of histone 3 within IL6 promoter.

    It is impossible to imagine the medical world today without radioisotopes, and due to rapid technological progress in nuclear medicine their use is still on the rise. An important role of research reactors is the production of molybdenum-99. Around the world this is done primarily by five nuclear research reactors, one of which is the BR2 reactor of SCK-CEN. As a result of checks and maintenance work on three other reactors, for a few years there has been a serious crisis in the availability of this medical isotope. In order to guarantee the worldwide supply of radioisotopes, SCK-CEN expanded its production of molybdenum-99 by 50 percent in 2010.

    Medical isotope production analyses in Kharkov Institute of Physics and Technology (KIPT) neutron source facility were performed to include the details of the irradiation cassette and the self-shielding effect. An updated detailed model of the facility was used for the analyses. The facility consists of an accelerator-driven system (ADS), which has a subcritical assembly using low-enriched uranium fuel elements with a beryllium-graphite reflector. The beryllium assemblies of the reflector have the same outer geometry as the fuel elements, which permits loading the subcritical assembly with different number of fuel elements without impacting the reflector performance. The subcritical assembly is driven by an external neutron source generated from the interaction of 100-kW electron beam with a tungsten target. The facility construction was completed at the end of 2015, and it is planned to start the operation during the year of 2016. It is the first ADS in the world, which has a coolant system for removing the generated fission power. Argonne National Laboratory has developed the design concept and performed extensive design analyses for the facility including its utilization for the production of different radioactive medical isotopes. 99 Mo is the parent isotope of 99m Tc, which is the most commonly used medical radioactive isotope. Detailed analyses were performed to define the optimal sample irradiation location and the generated activity, for several radioactive medical isotopes, as a function of the irradiation time.

    2012-01-01

    Background: Many academic medical centres have introduced strategies to assess the productivity of faculty as part of compensation schemes. We conducted a systematic review of the effects of such strategies on faculty productivity. Methods: We searched the MEDLINE, Healthstar, Embase and PsycInfo databases from their date of inception up to October 2011. We included studies that assessed academic productivity in clinical, research, teaching and administrative activities, as well as compensation, promotion processes and satisfaction. Results: Of 531 full-text articles assessed for eligibility, we included 9 articles reporting on eight studies. The introduction of strategies for assessing academic productivity as part of compensation schemes resulted in increases in clinical productivity (in six of six studies) in terms of clinical revenue, the work component of relative-value units (these units are nonmonetary standard units of measure used to indicate the value of services provided), patient satisfaction and other departmentally used standards. Increases in research productivity were noted (in five of six studies) in terms of funding and publications. There was no change in teaching productivity (in two of five studies) in terms of educational output. Such strategies also resulted in increases in compensation at both individual and group levels (in three studies), with two studies reporting a change in distribution of compensation in favour of junior faculty. None of the studies assessed effects on administrative productivity or promotion processes. The overall quality of evidence was low. Interpretation: Strategies introduced to assess productivity as part of a compensation scheme appeared to improve productivity in research activities and possibly improved clinical productivity, but they had no effect in the area of teaching. Compensation increased at both group and individual levels, particularly among junior faculty. Higher quality evidence about the benefits

    To assess changes in employee productivity impairment observed after the implementation of several Web-based health promotion programs. Health risk assessments and self-report measures of productivity impairment were administered on-line to more than 43,000 participants of Web-based health promotion programs. Reductions in productivity impairment were observed after 1 month of program utilization. Productivity impairment at 90- and 180-day follow-ups also decreased relative to baseline. Improvements in employee health were associated with reductions in employee productivity impairment. The use of Web-based health promotion programs was associated with reductions in productivity impairment and improvements in employee health. After the implementation of Web-based health promotion programs, reductions in productivity impairment may be observed before reductions in direct health care costs.

    In 2008, the Global strategy and plan of action on public health, innovation and intellectual property (GSPA-PHI) was launched by the World Health Organization, to stimulate fresh thinking on innovation in, and access to, medicines and to build sustainable research on diseases disproportionately affecting low- and middle-income countries. As part of the activities of the GSPA-PHI, Sri Lanka has been the first country to date to assess the national environment for medical technology and innovation. This year-long, multistakeholder, participative analysis facilitated identification of clear and implementable policy recommendations, for the government to increase its effectiveness in promoting innovation in health products through institutional development, investment and coordination among all areas relevant to public health. The assessment also highlighted areas for priority action, including closing the technology gap in development of health products, facilitating technology transfer, and building the health-research and allied workforces. The Sri Lankan experience will inform the ongoing independent external evaluation of the GSPA-PHI worldwide. The assessment process coincided with the passing of the National Medicines Regulatory Authority Act in 2015. In addition, there is growing recognition that regional cooperation will be critical to improving access to medical products in the future. Sri Lanka is therefore actively promoting cooperation to establish a regional regulatory affairs network. Lessons learnt from the Sri Lankan assessment may also benefit other countries embarking on a national GSPA-PHI assessment.

  4. The Educational Kanban: promoting effective self-directed adult learning in medical education.

    The author reviews the many forces that have driven contemporary medical education approaches to evaluation and places them in an adult learning theory context. After noting their strengths and limitations, the author looks to lessons learned from manufacturing on both efficacy and efficiency and explores how these can be applied to the process of trainee assessment in medical education.Building on this, the author describes the rationale for and development of the Educational Kanban (EK) at Children's Hospital Boston--specifically, how it was designed to integrate adult learning theory, Japanese manufacturing models, and educator observations into a unique form of teacher-student collaboration that allows for continuous improvement. It is a formative tool, built on the Accreditation Council for Graduate Medical Education's six core competencies, that guides educational efforts to optimize teaching and learning, promotes adult learner responsibility and efficacy, and takes advantage of the labor-intensive clinical educational setting. The author discusses how this model, which will be implemented in July 2009, will lead to training that is highly individualized, optimizes faculty and student educational efforts, and ultimately conserves faculty resources. A model EK is provided for general reference.The EK represents a novel approach to adult learning that will enhance educational effectiveness and efficiency and complement existing evaluative models. Described here in a specific graduate medical setting, it can readily be adapted and integrated into a wide range of undergraduate and graduate clinical educational environments.

    First quantitative evaluation of the requirements for the promotion as associate professor (AP) at German medical faculties. Analysis of the AP-regulations of German medical faculties according to a validated scoring system, which has been adapted to this study. The overall scoring for the AP-requirements at 35 German medical faculties was 13.5±0.6 of 20 possible scoring points (95% confidence interval 12.2-14.7). More than 88% of the AP-regulations demand sufficient performance in teaching and research with adequate scientific publication. Furthermore, 83% of the faculties expect an expert review of the candidate's performance. Conference presentations required as an assistant professor as well as the reduction of the minimum time as an assistant professor do only play minor roles. The requirements for assistant professors to get nominated as an associate professor at German medical faculties are high with an only small range. In detail, however, it can be seen that there still exists large heterogeneity, which hinders equal opportunities and career possibilities. These data might be used for the ongoing objective discussion.

    The growth chart has been proposed as an educational tool to make the child's growth visible to both health workers and caregivers and to enhance communication between them. In the case of growth faltering, this would trigger timely corrective measures. Although the relevance of growth monitoring and promotion (GMP) has often been questioned in the literature, opinions of District Medical Officers responsible for local implementation of GMP are unknown. The aim of this qualitative research was to explore the perceptions and difficulties of an international panel of District Medical Officers regarding GMP. As an exploratory study, in-depth interviews of an international panel of District Medical Officers (n=19) were conducted. Data were coded using the QSR Nudist 5.0 software. A discrepancy between intended purposes and practice of GMP was detected at two levels. First, lack of participation of care-givers was reported. Second, the District Medical Officers expressed a restrictive interpretation of the concept of growth monitoring. The communication with parents was never reported as a means or a result of GMP, neither as an evaluation criterion of programme efficiency. The growth chart was mainly considered a tool intended to be used by health services for the purpose of diagnosis. This two-fold discrepancy between the intention of international policy-planners and practice of local programme implementers could be a crucial factor affecting the performance of GMP. More emphasis should be put on social communication and involvement of caregivers.

  7. Medication of Production Animals – Cure of Malfunctioning Animals or Production Systems?

    Full Text Available Medication is used in all intensive animal productions. However, the increasing problems with resistant bacteria in all animal productions and in humans are supported by a number of reports. Special attention is given to the risk for transmitting food-borne (multi resistant zoonotic agents to humans due to failure in antibiotic treatment resulting in lower cure rates or higher case fatality rates. The use of medication in humans per se is capable of selecting for resistance in human pathogens. Nevertheless, the amount of used medication/antimicrobials in treatment of Danish production animals goes far beyond the amount used for human consumption. The increase in consumption has not been followed by a similarly increased mortality, e.g. illustrated by the number of rendered animals, increased use of injection medicine for veterinary treatments of diseased animals, or increased number of remarks on the carcasses from the slaughterhouses. Medication in animal production is facing its limits and relevant economic alternatives have to be developed. The strategy for the future must concentrate on using medication only for clinically diseased animals and not as a strategic treatment of the whole herd in order to maximise growth and camouflage of suboptimal production systems and insufficient management.

    Gender disparities within academic promotion have been reported in several medical specialties. Female representationin association with research productivity has not been reported among academic dermatologists. As research productivity is a heavily weighted factor in determining promotion, we sought to determine whether gender disparities in academic rank and scholarly impact, measured by the h-index, exist in academic dermatology. In 2015, the authors determined gender and academic rank using academic dermatology department websites. H- index and publication range were determined using the Scopus database. Rank, h-index, and publication range were compared between male and female academic dermatologists. The h-index of academic dermatologists increased with successive academic rank from Assistant Professor through Professor (p<0.001), although no significant difference existed between Chairs and Professors. Publication range also increased with each successive rank from Assistant Professor through Professor (p<0.001), with no statistical significant difference between publication range of Chairs and Professors. Overall, men had higher h-indices than female colleagues (p<0.001). This difference was maintained when controlling for academic rank among Assistant Professors, Professors, and Chairs and when controlling for publication range in years. Women in academic dermatology are underrepresented among senior academic ranks. The difference in scholarly productivity between male and female academic dermatologists may contribute to this disparity. Recommendation for earlyinvolvement in research activities may help minimize this gap.

    Our objectives were to evaluate collaboration with medical students and other nondoctoral authors, and assess whether mentoring such students influences the academic productivity of senior authors. Six issues of the Laryngoscope and International Forum of Allergy & Rhinology (IFAR) were examined for the corresponding author of each manuscript, and whether any students were involved in authorship. The h-index of all corresponding authors was calculated using the Scopus database to compare the scholarly impact of authors collaborating with students and those collaborating exclusively with other physicians or doctoral-level researchers. Of 261 Laryngoscope manuscripts, 71.6% had exclusively physician or doctoral-level authors, 9.2% had "students" (nondoctoral-level authors) as first authors, and another 19.2% involved "student" authors. Corresponding values for IFAR manuscripts were 57.1%, 6.3%, and 36.5%. Corresponding authors who collaborated with students had higher scholarly impact, as measured by the h-index, than those collaborating exclusively with physicians and doctoral-level scientists in both journals. Collaboration with individuals who do not have doctoral-level degrees, presumably medical students, has a strong association with scholarly impact among researchers publishing in the Laryngoscope and IFAR. Research mentorship of medical students interested in otolaryngology may allow a physician-scientist to evaluate the students' effectiveness and functioning in a team setting, a critical component of success in residency training, and may have beneficial effects on research productivity for the senior author. © 2013 ARS-AAOA, LLC.

    The study assessed 54 advertisements of 145 different drugs, published over one year (from December 2011 to November 2012) in an Indian medical journal, circulated widely mainly among general practitioners (GPs). The ethical guidelines of the World Health Organization (WHO) and Organisation of Pharmaceutical Producers of India (OPPI) for medicinal drug promotion were applied. The brand name was mentioned in all advertisements (100% compliance both with the WHO and OPPI criteria) and the names of the active ingredients were also mentioned in 128 (90.14%) advertisements. However, major adverse drug reactions were mentioned in only two advertisements (1.37%); precautions, contraindications and warnings in only two (1.37%); and major interactions in only one (0.68%). Only three advertisements (2.06%) were well substantiated with references. To ensure the ethical promotionof drugs among GPs, journals must introduce compulsory review and appraisal of promotional advertisements by a dedicated review board, including at least one member trained in pharmacology and one representative from the medical division of a pharmaceutical company.

The objective of this study is to determine the technological feasibility of radiation sterilization for the said products in the Philippines. They are polyvinyl chloride or polyethylene based medical plastic disposables namely: absorbent cotton, surgical gauze, bandage, visceral packs, and some antibiotics and opthalmic ointments. The gamma facility of the Philippine Atomic Energy Commission was used for the irradiation. Result of biological studies indicate no signs of toxicity on experimental mice injected with extracts from irradiated samples. The contaminants are identified as Pseudomonas Sp. Staphyloccocus Aureus and Bacillus Subtilis. The D 10 values of survivors of higher doses ranged below 0.235 Megarad suggesting that these contaminants can be eliminated by the generally used sterilizing dose of 2.5 Mrads. The physico-chemical tests did not indicate any significant degradation of the irradiated products. Opthalmic and topical antibiotic ointments showed no marked decrease in potency. Fading tests on dosimeters used showed that red perspex is a more efficient dosimeter than clear perspex when irradiation time is prolonged. (author)

    Food and beverage price promotions may be potential targets for public health initiatives but have not been well documented. We assessed prevalence and patterns of price promotions for food and beverage products in a nationwide sample of food stores by store type, product package size, and product healthfulness. We also assessed associations of price promotions with community characteristics and product prices. In-store data collected in 2010-2012 from 8959 food stores in 468 communities spanning 46 U.S. states were used. Differences in the prevalence of price promotions were tested across stores types, product varieties, and product package sizes. Multivariable regression analyses examined associations of presence of price promotions with community racial/ethnic and socioeconomic characteristics and with product prices. The prevalence of price promotions across all 44 products sampled was, on average, 13.4% in supermarkets (ranging from 9.1% for fresh fruits and vegetables to 18.2% for sugar-sweetened beverages), 4.5% in grocery stores (ranging from 2.5% for milk to 6.6% for breads and cereals), and 2.6% in limited service stores (ranging from 1.2% for fresh fruits and vegetables to 4.1% for breads and cereals). No differences were observed by community characteristics. Less-healthy versus more-healthy product varieties and larger versus smaller product package sizes generally had a higher prevalence of price promotion, particularly in supermarkets. On average, in supermarkets, price promotions were associated with 15.2% lower prices. The observed patterns of price promotions warrant more attention in public health food environment research and intervention. Copyright © 2016 Elsevier Inc. All rights reserved.

    Medical educators are increasingly faced with directives to teach Evidence Based Medicine (EBM) skills. Because of its nature, integrating fundamental EBM educational content is a challenge in the preclinical years. To analyse preclinical medical student user satisfaction and feedback regarding a clinical EBM search strategy. The authors introduced a custom EBM search option with a self-contained education structure to first-year medical students. The implementation took advantage of a major curricular change towards case-based instruction. Medical student views and experiences were studied regarding the tool's convenience, problems and the degree to which they used it to answer questions raised by case-based instruction. Surveys were completed by 70% of the available first-year students. Student satisfaction and experiences were strongly positive towards the EBM strategy, especially of the tool's convenience and utility for answering issues raised during case-based learning sessions. About 90% of the students responded that the tool was easy to use, productive and accessed for half or more of their search needs. This study provides evidence that the integration of an educational EBM search tool can be positively received by preclinical medical students.

    We performed a clinical study to evaluate the immune promotion and antioxidant effects of the developed product (HemoHIM) in healthy or subhealthy people. Volunteers with white blood cell numbers between 5000 and 10000/ul were recruited and the subjects were selected by appropriate inclusion and exclusion rules. The subjects were randomly assigned to 3 groups (HemoHIM 6g/day, HemoHIM 12g/day, Placebo). HemoHIM or placebo were adminstered for 2 months and the blood were collected and analyzed at 1 month and 2 month after the intake. The collected blood was analyzed for blood cell number, serum biochemical values (liver and kidney function), immunological activity of blood cells, antioxidant activity of blood plasma, and stress hormone level in the saliva. Finally the data of 88 subjects were analyzed for the immune promoting and antioxidant effects of HemoHIM. In results, no significant changes in blood cell numbers (white blood cell, lymphocyte, red blood cell) were observed in HemoHIM intake groups. However, NK cell activity were increased in HemoHIM intake groups and also IFN-gamma and IL-12, the biomarkers of immune cell functions, were increased in proportion to the dose and intake periode of HemoHIM. The antioxidant biomarker (TAS) was not significantly changed by HemoHIM intake. Besides, the serum biochemical analysis for liver and kidney functions, and the general medical examination showed the HemoHIM showed no side-effects, thus reconfirming its safety in humans. In conclusion, this study showed HemoHIM has a significant effects on the promotion of immune functions, while it has neither side-effects nor toxicity in humans. The results of this study may be utilized for the scientific data to acquire the Health Functional Food Certification of HemoHIM from Korea FDA

The regular medical examination of workers enables us to screen for numerous diseases, spread good practices and correct lifestyles, and obtain a favourable risk/benefit ratio. The continuous monitoring of the level of workers’ wellbeing using a holistic approach during medical surveillance enables us to promptly identify problems in work organisation and the company climate. Problems of this kind can be adequately managed by using a participatory approach. The aim of this paper is twofold: to signal this way of proceeding with medical surveillance, and to describe an organisational development intervention. Participatory groups were used to improve occupational life in a small company. After intervention we observed a reduction in levels of perceived occupational stress measured with the Effort/Reward Imbalance questionnaire, and an improvement in psychological wellbeing assessed by means of the Goldberg Anxiety/Depression scale. Although the limited size of the sample and the lack of a control group call for a cautious evaluation of this study, the participatory strategy proved to be a useful tool due to its cost-effectiveness.

    Improving energy productivity is one of the most cost-effective ways to achieve a sustainable development target. The existing literature has shown some factors that have driven the improvement in China’s energy productivity. However, these studies do little to tackle the role of Chinese local officials. Political promotions can be seen as the most important career incentive for Chinese local officials. Hence, we intend to study whether energy productivity affects Chinese local officials’ promotions in this paper. The data of position changes for the 31 provincial governors during 1978‐2012 are utilized. We adopted probit models to empirically examine the correlation between provincial governors’ political promotions and energy productivity. The empirical results demonstrate that (1) energy productivity has a significantly positive impact on provincial governors’ political promotions in China, meaning that the provincial governors have the momentum to improve energy productivity; and (2) the effect of energy productivity on provincial governors’ political promotions has evolved, dynamically changing along with the transformation of the economic growth mode and the adjustment of the local officials’ promotion mechanism. The results are helpful in understanding the drivers of the improvement in China’s energy productivity and provide insightful implications for conducting energy policy in China. - Highlights: •The data of position changes for China’s provincial governors during 1978–2012 are utilized. •Energy productivity has a positive impact on provincial governors’ promotion in China. •Political incentive is an important driver of the improvement in China’s energy productivity. •The correlation between energy productivity and local officials’ promotions was evolved.

    Full Text Available Choosing the content of promotional messages is a part of the activities of integrated marketing communication. As far as organic products in the world are concerned, research related to the choice of promotional message content is the object of much attention, primarily based on the conduct of research among the consumers of these product (information for defining the aim of promotion, creating and testing promotional messages, selecting media and media mix, and determining the number and frequency of promotional events. Promoting domestic organic products also inevitably implies conducting consumer-centred marketing research, in order to choose the appropriate promotional message. In this respect, this article defines several goals: study the choice of the promotional message content in relation to other activities of integrated marketing communication; consider this question in the context of relevant foreign market research into organic product consumers; determine the level of marketing research, which could be used for approaching the issue from the domestic perspective; and establish which recommendations and implication could be generated when domestic organic products are concerned.

    Reducing anthropogenic nutrient inputs is a major policy goal for restoring good environmental status of coastal marine ecosystems. However, it is unclear to what extent reducing nutrients would also lower fish production and fisheries yields. Empirical examples of changes in nutrient loads...... and concurrent fish production can provide useful insights to this question. In this paper, we investigate to what extent a multi-fold increase in nutrient loads from the 1950s to 1980s enhanced forage fish production in the Baltic Sea. We use monitoring data on fish stock dynamics covering the period...

    To identify factors associated with non-medical health professionals' engagement in physical activity (PA) promotion. Five electronic databases were searched for studies including practising health professionals (excluding medical doctors), a PA promotion practice measure, a test of association between potential influencing factors and PA promotion practice, and written in English. Two researchers independently screened studies and extracted data. Extracted data were synthesized in a tabular format with a narrative summary (thematic analysis). Thirty studies involving 7734 non-medical health professionals were included. Self-efficacy in PA promotion, positive beliefs in the benefits of PA, assessing patients' PA, and PA promotion training were the main factors associated with engaging in PA promotion. Lack of remuneration was not associated. Common study limitations included a lack of information on non-responders, data collection by survey only and limited reliability or validity testing of measurements. There are common factors influencing PA promotion, but the absence of studies from some health professions, limitations related to study measures, and the lack of randomised controlled intervention trials highlights the need for further research. The factors identified may prove useful for guiding the development of strategies to encourage greater engagement in PA promotion by health professionals. Copyright © 2018 Elsevier B.V.

    The objective of this study was the application of the synthetic promoter library (SPL) technology for modulation of actinorhodin production in Streptomyces coelicolor A3(2). The SPL technology was used to optimize the expression of a pathway specific positive transcriptional regulator Actll orf4...... constitutive promoter. ScoSPL20 demonstrated exceptional productivity despite having a comparatively weak expression from the promoter. Interestingly, the ScoSPL20 promoter was activated at a much earlier stage of growth compared to the wild type, demonstrating the advantage of fine-tuning and temporal tuning......, which activates the transcription of the S. coelicolor actinorhodin biosynthetic gene cluster. The native actll orf4 promoter was replaced with synthetic promoters, generating a S. coelicolor library with a broad range of expression levels of actll orf4. The resulting library was screened based...

    In recent years, medical practice has followed two different paradigms: evidence-based medicine (EBM) and values-based medicine (VBM). There is an urgent need to promote medical education that strengthens the relationship between these two paradigms. This work is designed to establish the foundations for a continuing medical education (CME) program aimed at encouraging the dialogue between EBM and VBM by determining the values relevant to everyday medical activities. A quasi-experimental, observational, comparative, prospective and qualitative study was conducted by analyzing through a concurrent triangulation strategy the correlation between healthcare personnel-patient relationship, healthcare personnel's life history, and ethical judgments regarding dilemmas that arise in daily clinical practice.In 2009, healthcare personnel working in Mexico were invited to participate in a free, online clinical ethics course. Each participant responded to a set of online survey instruments before and after the CME program. Face-to-face semi-structured interviews were conducted with healthcare personnel, focusing on their views and representations of clinical practice. The healthcare personnel's core values were honesty and respect. There were significant differences in the clinical practice axiology before and after the course (P ethical discernment, the CME program had an impact on autonomy (P ≤0.0001). Utilitarian autonomy was reinforced in the participants (P ≤0.0001). Regarding work values, significant differences due to the CME intervention were found in openness to change (OC) (P ethical discernment and healthcare personnel-patient relation were beneficence, respect and compassion, respectively. The healthcare personnel participating in a CME intervention in clinical ethics improved high-order values: Openness to change (OC) and Self Transcendence (ST), which are essential to fulfilling the healing ends of medicine. The CME intervention strengthened the role of

    TRIUMF has a long history of medical isotope production. For more than 40 years, the Life Sciences Division at TRIUMF has produced isotopes for Positron Emission Tomography (PET) for the local hospitals. Recently, the division has taken on the challenge to expand the facility's isotope repertoire to isotopes for imaging to treatment. At the smallest cyclotron at TRIUMF with energy of 13 MeV, radiometals are being produced in a liquid target which is typically used for PET isotope production. This effort makes radiometals available for early stage research and preclinical trials. At beam energy of 24 MeV, we produce 99mTc from 100Mo with a cyclotron, the most common isotope for Single-Photon-Emission-Computed-Tomography (SPECT) and the most common isotope for nuclear imaging. The use of a cyclotron bypasses the common production route via a nuclear reactor as well as enriched uranium. And finally, at our 500 MeV cyclotron we have demonstrated the production of α emitters useful for targeted alpha therapy. Herein, these efforts are summarized.

    The accelerator production of tritium (APT) facility, with its high beam current and high beam energy, would be an ideal supplier of radioisotopes for medical research, imaging, and therapy. By-product radioisotopes will be produced in the APT window and target cooling systems and in the tungsten target through spallation, neutron, and proton interactions. High intensity proton fluxes are potentially available at three different energies for the production of proton- rich radioisotopes. Isotope production targets can be inserted into the blanket for production of neutron-rich isotopes. Currently, the major production sources of radioisotopes are either aging or abroad, or both. The use of radionuclides in nuclear medicine is growing and changing, both in terms of the number of nuclear medicine procedures being performed and in the rapidly expanding range of procedures and radioisotopes used. A large and varied demand is forecast, and the APT would be an ideal facility to satisfy that demand

    The purpose of this study is to find a proper prehospital transportation scenario planning of an emergency medical service (EMS) system for possible burdensome casualties resulting from extreme climate events. This project focuses on one of the worst natural catastrophic events in Taiwan, the 88 Wind-caused Disasters, caused by the Typhoon Morakot; the case of the EMS transportation in the Xiaolin village is reviewed and analyzed. The sequential-conveyance method is designed to promote the efficiency of all the ambulance services related to transportation time and distance. Initially, a proposed mobile emergency medical center (MEMC) is constructed in a safe location near the area of the disaster. The ambulances are classified into 2 categories: the first-line ambulances, which reciprocate between the MEMC and the disaster area to save time and shorten the working distances and the second-line ambulances, which transfer patients in critical condition from the MEMC to the requested hospitals for further treatment. According to the results, the sequential-conveyance method is more efficient than the conventional method for EMS transportation in a mass-casualty incident (MCI). This method improves the time efficiency by 52.15% and the distance efficiency by 56.02%. This case study concentrates on Xiaolin, a mountain village, which was heavily destroyed by a devastating mudslide during the Typhoon Morakot. The sequential-conveyance method for the EMS transportation in this research is not only more advantageous but also more rational in adaptation to climate change. Therefore, the findings are also important to all the decision-making with respect to a promoted EMS transportation, especially in an MCI.

    The availability of reactor-produced radioisotopes in the United States for use in medical research and nuclear medicine has traditionally depended on facilities which are an integral part of the US national laboratories and a few reactors at universities. One exception is the reactor in Sterling Forest, New York, originally operated as part of the Cintichem (Union Carbide) system, which is currently in the process of permanent shutdown. Since there are no industry-run reactors in the US, the national laboratories and universities thus play a critical role in providing reactor-produced radioisotopes for medical research and clinical use. The goal of this survey is to provide a comprehensive summary of these production capabilities. With the temporary shutdown of the Oak Ridge National Laboratory (ORNL) High Flux Isotope Reactor (HFIR) in November 1986, the radioisotopes required for DOE-supported radionuclide generators were made available at the Brookhaven National Laboratory (BNL) High Flux Beam Reactor (HFBR). In March 1988, however, the HFBR was temporarily shut down which forced investigators to look at other reactors for production of the radioisotopes. During this period the Missouri University Research Reactor (MURR) played an important role in providing these services. The HFIR resumed routine operation in July 1990 at 85 MW power, and the HFBR resumed operation in June 1991, at 30 MW power. At the time of the HFBR shutdown, there was no available comprehensive overview which could provide information on status of the reactors operating in the US and their capabilities for radioisotope production. The obvious need for a useful overview was thus the impetus for preparing this survey, which would provide an up-to-date summary of those reactors available in the US at both the DOE-funded national laboratories and at US universities where service irradiations are currently or expected to be conducted

    To identify whether regional differences exist in gender disparities in scholarly productivity and faculty rank among academic otolaryngologists. Academic otolaryngologists' bibliometric data analyses. Online faculty listings from 98 otolaryngology departments were organized by gender, academic rank, fellowship training status, and institutional location. The Scopus database was used to assess bibliometrics of these otolaryngologists, including the h-index, number of publications, and publication experience. Analysis included 1127 otolaryngologists, 916 men (81.3%) and 211 women (18.7%). Female faculty comprised 15.4% in the Midwest, 18.8% in the Northeast, 21.3% in the South, and 19.0% in the West (P = .44). Overall, men obtained significantly higher senior academic ranks (associate professor or professor) compared to women (59.8% vs. 40.2%, P .05). Gender disparities in academic rank and scholarly productivity exist most notably in the Northeast, where women in otolaryngology are most underrepresented relative to men at senior academic ranks and in scholarly productivity.

    The objective of this project is to experimentally verify and enhance Mo-99 and Sr-89 recovery/purification processes as the key technologies for the medical isotope production from a solution fuel reactor. A joint experiment was planned between KAERI and Kurchatov Institute (KI), Russia. The kinds of experiments planed are, a series of Mo-99 recovery/purification experiments from the ARGUS reactor which uses High Enriched Uranium (HEU) fuel, a series of the same experiments but from the Low Enriched Uranium (LEU) solution target, a demonstration of the mechanism of Sr-89 delivery from the air medium in the reactor vessel. Meanwhile, the survey and legalistic interpretation of relevant patents shows a possibility of infringement of TCI Inc.'s patents in case of exporting medical isotopes produced at the MIP to Japan and the US so far as the MIP adopts the concept of the Russian ARGUS and recovery/purification process. Eliminating, not minor changing, step(s) or condition(s) of patent processes would help to avoid the patent infringement. Because of a difficulty in the KAERI-KI full-time co-experiments at KI labs, a different idea between two parties about the depth of background information to be provided to KAERI, and other reasons, the experiment plan was not executed

    High energy neutrons produced in DT fusion reactors have a secondary application for use in the synthesis of valuable man-made isotopes utilized in industry today. One such isotope is metastable Technecium-99 (Tc99m), a low energy gamma emitter used in ~ 85% of all medical imaging diagnostics. Tc99m is created through beta decay of Molybdenum-99 (Mo99), which itself has only a 66 hour half-life and must be created from a neutron capture by the widely available and stable isotope Molydenum-98. Current worldwide production of Tc99m occurs in just five locations and relies on obtaining the fission byproduct Mo99 from highly enriched Uranium reactors. A Tc99m generator using DT fusion neutrons, however, could potentially be operated at individual hospitals and medical facilities without the use of any fissile material. The neutron interaction of the DT neutrons with Molybdenum in a potential device geometry was modeled using Monte Carlo neutron transport code MCNP. Trial experiments were also performed to test the viability of using DT neutrons to create ample quantities of Tc99m. Modeling and test results will follow.

    Sally Dunlop

    2016-06-01

    Full Text Available The near-ubiquitous use of social media among adolescents and young adults creates opportunities for both corporate brands and health promotion agencies to target and engage with young audiences in unprecedented ways. Traditional media is known to have both a positive and negative influence on youth health behaviours, but the impact of social media is less well understood. This paper first summarises current evidence around adolescents’ exposure to the promotion and marketing of unhealthy products such as energy dense and nutrient poor food and beverages, alcohol, and tobacco on social media sites such as Facebook, Twitter, Instagram and YouTube. We explore emerging evidence about the extent of exposure to marketing of these harmful products through social media platforms and potential impacts of exposure on adolescent health. Secondly, we present examples of health-promoting social media campaigns aimed at youth, with the purpose of describing innovative campaigns and highlighting lessons learned for creating effective social media interventions. Finally, we suggest implications for policy and practice, and identify knowledge gaps and opportunities for future research.

    Mani, R.S.

    1985-01-01

    More than 70% of all radioisotopes applied in medical diagnosis and research are currently produced in research reactors. Research reactors are also an important source of certain radioisotopes, such as 60 Co, 90 Y, 137 Cs and 198 Au, which are employed in teletherapy and brachytherapy. For regular medical applications, mainly 29 radionuclides produced in research reactors are used. These are now produced on an 'industrial scale' by many leading commercial manufacturers in industrialized countries as well as by national atomic energy establishments in developing countries. Five main neutron-induced reactions have been employed for the regular production of these radionuclides, namely: (n,γ), (n,p), (n,α), (n,γ) followed by decay, and (n, fission). In addition, the Szilard-Chalmers process has been used in low- and medium-flux research reactors to enrich the specific activity of a few radionuclides (mainly 51 Cr) produced by the (n,γ) reaction. Extensive work done over the last three decades has resulted in the development of reliable and economic large-scale production methods for most of these radioisotopes and in the establishment of rigorous specifications and purity criteria for their manifold applications in medicine. A useful spectrum of other radionuclides with suitable half-lives and low to medium toxicity can be produced in research reactors, with the requisite purity and specific activity and at a reasonable cost, to be used as tracers. Thanks to the systematic work done in recent years by many radiopharmaceutical scientists, the radionuclides of several elements, such as arsenic, selenium, rhenium, ruthenium, palladium, cadmium, tellurium, antimony, platinum, lead and the rare earth elements, which until recently were considered 'exotic' in the biomedical field, are now gaining attention.

    Medical isotope facilities operating in the 10 to 25 MeV proton energy range have long been used to generate radioisotopes for medical diagnostic imaging. In the last few years the beam currents available in commercially available cyclotrons have increased dramatically, and so the activation of the materials within cyclotron vaults may now pose more serious radiological hazards. This will impact the regulatory oversight of cyclotron operations, cyclotron servicing and future decommissioning activities. Air activation could pose a hazard to cyclotron staff. With the increased cyclotron beam currents it was necessary to examine the issue more carefully. Therefore the ways in which radioactivity may be induced in air by neutron reactions and neutron captures were considered and it was found that the dominant mechanism is neutron capture on Ar-40. A study of the activation of the air by neutron capture on Ar-40 within a cyclotron vault was performed using the MCNP Monte Carlo code. The neutron source energy spectrum used was from the production of the widely used F-18 PET isotope. The results showed that the activation of the air within a cyclotron vault does not pose a significant radiological hazard at the beam intensities currently in use and shows how ventilation affects the results. A second MCNP study on the activation of ordinary concrete in cyclotron vaults by neutron capture was made with a view to determining the optimum thickness of borated polyethylene to reduce neutron activation on both the inner surfaces of the vault and around production targets. This is of importance in decommissioning cyclotrons and therefore in the design of new cyclotron vaults. The distribution of activation on the walls as a function of the source position was also studied. Results are presented for both borated and regular polyethylene, and F-18 and Tc-99 neutron spectra.

    Full Text Available Medical services are the most important services of all since we all depend on them. Their quality and productivity can assure a wealthy nation and therefore good economical results. The offer of medical services depends on medical personnel and more than this, on the management in the medical field since any resource not managed well or not managed at all is only a lost one, regardless its value. Management is therefore the key, the “how to” method of obtaining the desired result. The same approach can be applied into our study in order to reach more productive medical services which to prove high quality to all patients. We need to use and to squeeze the entire force of management tools in order to reach our goal: accessible medical services full of quality. The current worldwide crisis situation makes us think that after job and food, even medical services (also a basic thing after all can become a “luxury” although this should never happen. Therefore we must do whatever needed to improve the way medical organizations are driven so that the quality of their medical services will be better and better and the productivity will be at a higher level. Medical management should have as a goal making it possible for patients to be able to solve their health problems as soon as possible and as good as possible.

    Spermine oxidase (SMOX) catalyzes oxidation of spermine to generate spermidine, hydrogen peroxide (H 2 O 2 ) and 3-aminopropanal, which is spontaneously converted to acrolein. SMOX is induced by a variety of stimuli including bacterial infection, polyamine analogues and acetaldehyde exposure. However, the physiological functions of SMOX are not yet fully understood. We investigated the physiological role of SMOX in liver cells using human hepatocellular carcinoma cell line HepG2. SMOX localized to the bile canalicular lumen, as determined by F-actin staining. Knockdown of SMOX reduced the formation of bile canalicular lumen. We also found that phospho-Akt (phosphorylated protein kinase B) was localized to canalicular lumen. Treatment with Akt inhibitor significantly reduced the formation of bile canalicular lumen. Acrolein scavenger also inhibited the formation of bile canalicular lumen. PTEN, phosphatase and tensin homolog and an inhibitor of Akt, was alkylated in a SMOX-dependent manner. Our results suggest that SMOX plays a central role in the formation of bile canalicular lumen in liver cells by activating Akt pathway through acrolein production.

    Full Text Available Background: Preceptors rarely follow medical students’ developing clinical performance over time and across disciplines. This study analyzes preceptors’ descriptions of longitudinal integrated clerkship (LIC students’ clinical development and their identification of strategies to guide students’ progress. Methods: We used a common evaluation framework, reporter-interpreter-manager-educator, to guide multidisciplinary LIC preceptors’ discussions of students’ progress. We conducted thematic analysis of transcripts from preceptors’ (seven longitudinal ambulatory preceptors per student quarterly group discussions of 15 students’ performance over one year. Results: All students’ clinical development progressed, although most experienced obstacles. Lack of structure in the history and physical exam commonly obstructed progression. Preceptors used templates for data gathering, and modeling or experiences in the inpatient setting to provide time and solidify structure. To advance students’ knowledge acquisition, many preceptors identified focused learning topics with their students; to promote application of knowledge, preceptors used reasoning strategies to teach the steps involved in synthesizing clinical data. Preceptors shared accountability for helping students advance as the LIC allowed them to follow students’ response to teaching strategies. Discussion: These results depict preceptors’ perceptions of LIC students’ developmental continuum and illustrate how multidisciplinary preceptors can use a common evaluation framework to identify strategies to improve performance and follow students’ performance longitudinally.

    The objective of this study was the application of the synthetic promoter library (SPL) technology for modulation of actinorhodin production in Streptomyces coelicolor A3(2). The SPL technology was used to optimize the expression of a pathway specific positive transcriptional regulator ActII orf4, which activates the transcription of the S. coelicolor actinorhodin biosynthetic gene cluster. The native actII orf4 promoter was replaced with synthetic promoters, generating a S. coelicolor library with a broad range of expression levels of actII orf4. The resulting library was screened based on the yield of actinorhodin. Selected strains were further physiologically characterized. One of the strains from the library, ScoSPL20, showed considerably higher yield of actinorhodin and final actinorhodin titer, compared to S. coelicolor wild type and S. coelicolor with actII orf4 expressed from a strong constitutive promoter. ScoSPL20 demonstrated exceptional productivity despite having a comparatively weak expression from the promoter. Interestingly, the ScoSPL20 promoter was activated at a much earlier stage of growth compared to the wild type, demonstrating the advantage of fine-tuning and temporal tuning of gene expression in metabolic engineering. Transcriptome studies were performed in exponential and actinorhodin-producing phase of growth to compare gene expression between ScoSPL20 and the wild type. To our knowledge, this is the first successful application of the SPL technology for secondary metabolite production in filamentous bacteria. PMID:24963940

    In late 1994, Sandia National Laboratories in Albuquerque, New Mexico, (SNL/NM), was instructed by the Department of Energy (DOE) Isotope Production and Distribution Program (IPDP) to examine the feasibility of producing medically useful radioisotopes using the Annular Core Research Reactor (ACRR) and the Hot Cell Facility (HCF). Los Alamos National Laboratory (LANL) would be expected to supply the targets to be irradiated in the ACRR. The intent of DOE would be to provide a capability to satisfy the North American health care system demand for 99 Mo, the parent of 99m Tc, in the event of an interruption in the current Canadian supply. 99m Tc is used in 70 to 80% of all nuclear medicine procedures in the US. The goal of the SNL/NM study effort is to determine the physical plant capability, infrastructure, and staffing necessary to meet the North American need for 99 Mo and to identify and examine all issues with potential for environmental impact

    Photosynthetic rate, RuBP Carboxylase activity, glycolate oxidase activity, malate dehydrogenase activity, specific leaf weight, harvest index and yield were estimated in the normal and 10 Krad dose treated M 2 plants of Vigna sublobata (wild), V. radiata and V. mungo (cultivars) with the objective of locating and utilizing productivity promoting gene assemblies as well as to understand the role of natural and artificial selections in moulding yield promoting gene combinations. The results suggest that there is higher photosynthetic rate and RuPB Case activity in the 10 Krad treated M 2 plants. There is lesser glycolate oxidase activity and malate dehydrogenase activity. There is also positive correlation among net leaf assimilation rate, RuBP Case activity, SLW, HI and yield. These observations imply that domestication accompanied by directional selection did a lter substantially the productivity traits and productivity promoting gene assemblies.

    1990-01-01

    The semiindustrial plant of irradiation located at the Atomic Center of Ezeiza entered into operation 20 years ago. This plant has a nominal activity of 3.7 x 10 16 Bq (10 6 Ci) and is presently operating with 1.78 x 10 16 Bq (4.8 x 10 5 Ci). The facility allows working in pilot plant scale for the study of industrial applications and also performs commercial services, the most important of which considering its volume, economic significance and social function is the radiosterilization of disposable medical products. Approximately 29,000 m 3 have been processed in this period, most of the materials being polymers, as component parts of the products as well as packaging. To validate the process of radiosterilization the materials compatibility with ionizing radiation must be known. In the department that operates the irradiation plant, the polymer laboratory is involved in the development of industrial applications and also in the subject of compatibility of polymers with radiosterilization. The laboratory gives advice on request about selection of materials as well as relevant information for the evaluation of radiation resistance and stability, including exposition doses for the samples and mechanical, physical or chemical tests according to the kind of product. In many occasions this laboratory has had to undertake these tests because local manufacturers of medical products not always have adequate facilities for quality control. Among mechanical tests the area under the stress-strain curve as a measure of the strain the material can undergo without fracture is perhaps the best for the evaluation of degradation. Among physical properties it is important to evaluate discoloration, usual in plastics irradiation, and concerning chemical tests the detection of migration of components from the polymer proves important in some cases. Although the irradiator cannot assume any responsibility concerning compatibility, local experience has shown the importance of having a

    The purpose of this study was to perform a medical audit of the screening of mammographic results according to ACR BI-RADS Follow-Up and Outcome Monitoring and to evaluate the efficacy of screening mammography in the early detection of breast cancer. We reviewed the results of 15,300 mammographic examinations of 13,889 women aged 30-75 years who underwent mammography at least once at the Severance Health Promotion Center between 1994-1998. Women with abnormal mammographic findings were recalled for additional study and those with dense breast composition (3, 4) underwent additional ultrasound. All results were categorized on the basis of the ACR BI-RADS final assessment scale, 1-5. We reviewed the pathologic or follow-up results of all women in categories 4 and 5, and/or those in any category who took the films out of the health center. The recall rate was 13%. Biopsy or surgical consultation was recommended for 92 women and biopsy was performed in 52. Pathology revealed 17 cancers and 35 benign lesions. Positive predictive value 2 was found in 18.5% of cases, and positive predictive value 3 in 33%. The cancer detection rate was 1.2/1,000, and sensitivity was 89.5%. Invasive cancers smaller than 1 cm or in situ ductal cancers were found in eight of 17 cases (47%), while node-positive invasive cancers were found in nine of 14 cases (64%). Four of 17 mammographically detected cancers were palpated by a surgeon. In asymptomatic women, screening mammography is an effective method for the detection of early breast cancer. (author)

  15. Interspecific neighbor interactions promote the positive diversity-productivity relationship in experimental grassland communities.

    Directory of Open Access Journals (Sweden)

    Yuhua Zhang

    Full Text Available Because the frequency of heterospecific interactions inevitably increases with species richness in a community, biodiversity effects must be expressed by such interactions. However, little is understood how heterospecific interactions affect ecosystem productivity because rarely are biodiversity ecosystem functioning experiments spatially explicitly manipulated. To test the effect of heterospecific interactions on productivity, direct evidence of heterospecific neighborhood interaction is needed. In this study we conducted experiments with a detailed spatial design to investigate whether and how heterospecific neighborhood interactions promote primary productivity in a grassland community. The results showed that increasing the heterospecific: conspecific contact ratio significantly increased productivity. We found there was a significant difference in the variation in plant height between monoculture and mixture communities, suggesting that height-asymmetric competition for light plays a central role in promoting productivity. Heterospecific interactions make tall plants grow taller and short plants become smaller in mixtures compared to monocultures, thereby increasing the efficiency of light interception and utilization. Overyielding in the mixture communities arises from the fact that the loss in the growth of short plants is compensated by the increased growth of tall plants. The positive correlation between species richness and primary production was strengthened by increasing the frequency of heterospecific interactions. We conclude that species richness significantly promotes primary ecosystem production through heterospecific neighborhood interactions.

    Ramon Solves Pujol

    2010-01-01

    Full Text Available This paper proposes the use of social psychological and philosophical foundations for designing affective technology that promotes the experience of love. The adopted theoretical basis is the concept of productive love, which is heavily based on Enrich Fromm but also includes theories and scientific findings of numerous psychoanalysts, social psychologists, and philosophers. We conducted a review of the theory about the nature of love and found that social psychological and philosophical approaches differ regarding peoples' understandings. The findings were used to elaborate eight principles of productive love. Based on these principles, we derived criteria for designing affective technology when the objective is to promote productive love. We reviewed the existent studies on affective technologies and implemented the criteria into a system design, the Pictures' Call. A prototype of the system was pretested to illustrate how productive love technology could be based on established criteria.

    Full Text Available Chain and market-oriented dairy sustainability, nutritional and social objectives related to the promotion of behaviours aimed at the development are essential. At the same time, the signifi cance of the various forms of sales promotion, as a factor of consumer buying behaviour infl uence, increases. The study includes the use of the sales promotion instruments in commercial space, perceived by consumers and assessment of their impact on purchasing decisions. The study was carried out on the basis of a standardized authoring individual interview questionnaire on nationwide random-quota, registered trials, in 2007–2012, as a part of the study of consumer behaviour performed in the dairy market for KZSM (National Association of Dairy Cooperatives. The results confi rm that the effect of promotion activities is a high visibility by consumers and change of their purchasing decisions. The most important determinant of consumer purchasing behaviour are the price promotions. Most often supported by a complete set of sales promotion instruments have been modern dairy products – yoghurt, grainy and ripening cheese. Sales promotion is an important instrument of balancing the dairy market and shaping the desired behaviour of consumers.

    2007-03-01

    We estimated the strength and direction of the association between product characteristics (beer type, package size, and brand name) and market-area socioeconomic characteristics, and promoted sales of beer in grocery stores. Supermarket scanner data from 64 market areas across the United States over 5 years were used to estimate regression models of the share of beer sales that are promoted, controlling for beer price, packaging, and type; and for market-level age, race/ethnicity, income, unemployment rate, and percentage of the population living in an alcohol control state. Large-volume units, such as 144-oz and 288-oz packages, are more likely to be promoted than smaller package sizes. Malt-liquor beverages are less likely to be promoted than non-malt-liquor beverages. Age, race/ethnicity, income, and geographic location of the market area are not significantly related to promoted beer sales. Marketing research has shown that in-store merchandising and promotions can substantially increase beer sales and that purchasing large package sizes may increase total consumption. Our results suggest that high levels of promoted sales for large-volume beer packages may result in increased beer consumption.

  2. Principlism, medical individualism, and health promotion in resource-poor countries: can autonomy-based bioethics promote social justice and population health?

    Science.gov (United States)

    Azétsop, Jacquineau; Rennie, Stuart

    2010-01-18

    Through its adoption of the biomedical model of disease which promotes medical individualism and its reliance on the individual-based anthropology, mainstream bioethics has predominantly focused on respect for autonomy in the clinical setting and respect for person in the research site, emphasizing self-determination and freedom of choice. However, the emphasis on the individual has often led to moral vacuum, exaggeration of human agency, and a thin (liberal?) conception of justice. Applied to resource-poor countries and communities within developed countries, autonomy-based bioethics fails to address the root causes of diseases and public health crises with which individuals or communities are confronted. A sociological explanation of disease causation is needed to broaden principles of biomedical ethics and provides a renewed understanding of disease, freedom, medical practice, patient-physician relationship, risk and benefit of research and treatment, research priorities, and health policy.

  10. Pharmaceutical speakers' bureaus, academic freedom, and the management of promotional speaking at academic medical centers.

    Science.gov (United States)

    Boumil, Marcia M; Cutrell, Emily S; Lowney, Kathleen E; Berman, Harris A

    2012-01-01

    Pharmaceutical companies routinely engage physicians, particularly those with prestigious academic credentials, to deliver "educational" talks to groups of physicians in the community to help market the company's brand-name drugs. Although presented as educational, and even though they provide educational content, these events are intended to influence decisions about drug selection in ways that are not based on the suitability and effectiveness of the product, but on the prestige and persuasiveness of the speaker. A number of state legislatures and most academic medical centers have attempted to restrict physician participation in pharmaceutical marketing activities, though most restrictions are not absolute and have proven difficult to enforce. This article reviews the literature on why Speakers' Bureaus have become a lightning rod for academic/industry conflicts of interest and examines the arguments of those who defend physician participation. It considers whether the restrictions on Speakers' Bureaus are consistent with principles of academic freedom and concludes with the legal and institutional efforts to manage industry speaking. © 2012 American Society of Law, Medicine & Ethics, Inc.

    Little information exists on the research productivity of successfully promoted tenure-track Doctor of Physical Therapy (DPT) faculty. To determine the research productivity that typically results in successful promotion. We collected publicly available curriculum vitae (CVs) from faculty currently in accredited DPT programs and who had been successfully promoted from an institution in the southeastern USA from 2000 through 2016. Total publication count, journal impact factor, funding, citations, and other metrics were analysed from 45 subjects of 22 of the 64 CAPTE-accredited DPT programs in the southeast. None of the studied metrics were normally distributed with time to promotion as determined by a Shapiro-Wilk test. These faculty exhibited a median publication count of 4, range 0 to 43; median of average citation count of 12.4, range 0 to 87.25; median of average journal impact factor of 2.866, range 0 to 6.280; median external funding received of $9910, range $0.00 to $19 543 198; and median author h-index of 3, range 0 to 17. The median number of years before promotion was 6, ranging from 3 to 13 years. Linear regression analysis indicates a poor fit with no significant correlation between years before promotion and any of the studied metrics. No correlation between journal impact factor and number of citations was observed (m = -0.22, p = 0.728, R 2  = 0.0003). Prior to promotion 31% (14 of 45) did not receive external funding and 24% (11 of 45) had a 0 h-index. The Carnegie Classification of the institution did not significantly correlate with research productivity metrics in this dataset (p = 0.213). While faculty unsuccessful in promotion were not identifiable using this method, this research can be used by faculty and committees to evaluate research productivity against regional data and promote competitive standards with peer institutions.

    2010-07-01

    It is becoming increasingly important for today's medical technologists to receive proper training on the safety of medical treatment and healthcare in order to accommodate the rapid changes and advancement in medical technology. In particular, because of the increase of hospital-acquired infections, the role of medical technologists involved in infection control has become much more important. In addition, particularly in Japan, the career options available to students graduating with a degree in medical technology have become much more diverse, ranging from research laboratories to clinical services; however, undergraduate education for medical technologists is limited. It is therefore deemed necessary for undergraduate students to be provided with adequate training from their universities by offering a wider selection of classes in this subject area. In this paper, we summarize our preliminary findings on the trial lessons that are offered to medical technology students in their microbiology class. These lessons are designed to enhance students' academic potential and to engage their interest.

    2012-07-01

    This study assessed the impact of a pre-medical pipeline program on successful completion of medical school and the capacity of this program to address achievement gaps experienced by disadvantaged students. The University of North Carolina (USA) Medical Education Development (MED) program provides intensive academic and test skills preparation for admission to medical, dental, and other allied health professions schools. This retrospective study evaluated the academic progress of a longitudinal sample of 1738 disadvantaged college students who completed MED between 1974 and 2001. Data sources included MED participant data, medical school admissions data for the host school, aggregate data from the Association of American Medical Colleges (AAMC), and individual MED participant data from AAMC. Methods of analysis utilized Chi-square, independent samples t test, and logistic regression to examine associations between factors. Of the 935 students in MED from 1974 to 2001, who had indicated an interest in medical school, 887 (94.9%) successfully matriculated and 801 (85.7%) successfully earned the MD degree. Using logistic regression, factors that were significantly correlated with earning the medical degree included the student's race, college undergraduate total and science grade point averages, with Hispanic, African American, and Native American participants earning the medical degree at rates comparable to Caucasian participants. MED students successfully earned the MD degree despite having significantly lower Medical College Admissions Test (MCAT) scores and undergraduate grade point averages compared to all United States medical school applicants: MCAT scores had little relationship with student's success. These findings suggest that an intensive, nine-week, pre-medical academic enrichment program that incorporates confidence-building and small-group tutoring and peer support activities can build a foundation on which disadvantaged students can successfully earn

    2017-09-01

    Full Text Available Objective: To evaluate the beliefs of medical university students regarding male circumcision (MC, as well as attitudes and the predictors of its promotion in the case of adults at risk of HIV. Methods: A cross-sectional survey was conducted between 2013–2016 at the Medical University in Szczecin, Poland, among final year Polish/foreign students from Northern Europe, using a standardized questionnaire. Results: There were 539 participants, median age 25 years, 40.8% males, and 66.8% were Polish nationals. The MC rate was 16.7%. Regarding HIV/AIDS knowledge, 66.6% of the students scored more than 75%; and, 34.2% knew that MC reduces the risk of HIV infection. One in eleven respondents (9.1% believed that circumcised men felt more intense sexual pleasure. More than half of the respondents (54.8% declared that they would recommend MC to adult patients at risk for HIV. The belief that circumcised men felt more intense sexual pleasure, and knowledge on MC regarding HIV risk reduction was associated with greater odds of recommending adult MC (OR = 3.35 and OR = 2.13, respectively. Conclusions: Poor knowledge of its benefits and a low willingness to promote the procedure—strongly dependent on personal beliefs—suggest that medical students may need additional training to help them to discuss MC more openly with adult men at risk for HIV infection. Knowledge may be an effective tool when making decisions regarding MC promotion.

    Given recent emphasis on professionalism training in medical schools by accrediting organizations, medical ethics and humanities educators need to develop a comprehensive understanding of this emphasis. To achieve this, the Project to Rebalance and Integrate Medical Education (PRIME) II Workshop (May 2011) enlisted representatives of the three major accreditation organizations to join with a national expert panel of medical educators in ethics, history, literature, and the visual arts. PRIME II faculty engaged in a dialogue on the future of professionalism in medical education. The authors present three overarching themes that resulted from the PRIME II discussions: transformation, question everything, and unity of vision and purpose.The first theme highlights that education toward professionalism requires transformational change, whereby medical ethics and humanities educators would make explicit the centrality of professionalism to the formation of physicians. The second theme emphasizes that the flourishing of professionalism must be based on first addressing the dysfunctional aspects of the current system of health care delivery and financing that undermine the goals of medical education. The third theme focuses on how ethics and humanities educators must have unity of vision and purpose in order to collaborate and identify how their disciplines advance professionalism. These themes should help shape discussions of the future of medical ethics and humanities teaching.The authors argue that improvement of the ethics and humanities-based knowledge, skills, and conduct that fosters professionalism should enhance patient care and be evaluated for its distinctive contributions to educational processes aimed at producing this outcome.

    2012-01-01

    Mushrooms such as Agaricus bisporus, are cultivated for food worldwide. Fruit body initiation in Agaricus bisporus is a phase change from the vegetative to the reproductive stage which depends on the presence of a casing layer with particular physical, chemical and microbiological properties. The phase change is achieved practically by environmental manipulation and the presence of naturally occurring bacteria such as Pseuodomonas putida. In this study, 274 individual bacterial isolates were collected by screening the casing layer of 14 edible mushroom farms. The isolates were analysed with respect to biochemical properties, organic and inorganic phosphate solubilization, production of siderophore and growth in the presence of volatile compound of 1-octen-3-ol. It was found that approximately 97% of the strains were able to grow in the presence of 1-octen-3-ol and 36% were able to solubilize phosphorus. Among the isolates, 23 strains were selected as potent mushroom growth promoting bacteria (MGPB) for inoculation of the casing layer. Field experiments using these strains showed various promoting effects on production of mushroom. Finally, 2 strains (strains Bt4 and Ps7) showing the highest increase in A. bisporus production, were characterized as Pseuodomonas putida by molecular methods and identified as the best suited growth promoting inoculants for application in production farms for increasing the mushroom yield.

    2011-01-01

    The paper analyses unlabelled advertorials about health products in four life-style magazines and three daily newspapers' life-style supplements in Slovenia. Based on 250 hours of observing the production practice, 20 in-depth interviews with the main participants and a textual analysis of 247 advertorials, supported by three detailed case studies, the process of unlabelled advertorial production was unveiled, reasons for their production explained and their discursive elements of promotion uncovered. Despite their typical news-like appearance, advertorials focus on a product's positive characteristics only and represent an oversimplified viewpoint on health, primarily oriented towards the interest of the pharmaceutical industry. In advertorials, readers are instructed in healthy living and caring about their health through buying the promoted product. No particular differences were found between the magazines and quality dailies' supplements, indicating that the advertorial practice has become a common part of the Slovenian press media scene. The outburst of advertorials in Slovenia is outstanding due to the lack of historical democracy, problems with the supervision of legal transgressions, the small media and advertising market, economic downturns and the financial weakness of the media.

    2017-01-01

    Full Text Available Background: Pharmaceutical drug promotion is an important component of pharmaceutical care and is one of the factors that may lead to unethical drug prescriptions. As the impetus for rational drug use grows, emphasis should also be focused on prescribing behaviors of physicians, particularly in resource-poor settings. Aim: The study was aimed at describing the influence of drug promotion by pharmaceutical sales representatives (PSRs on the prescribing behaviors of medical practitioners in Abia State, Nigeria. Materials and Methods: A descriptive study was carried out on a cross-section of 185 medical practitioners in Abia State, Nigeria. Data collection was done using a pretested, self-administered questionnaire that elicits information on practice and attitude to drug promotion, types of incentives, frequency of visits, drug promotion methods and information, sources of drug information, and awareness of code of regulation on drug promotion. Results: The age of the participants ranged from 28 to 71 years. There were 166 males and 19 females. The prescribing practices of 47.6% of the medical practitioners were influenced by drug promotion and 66.5% of them had positive attitude to drug promotion. One hundred and sixty-four (88.6% were visited >12 times in the previous year. The most common incentive received was branded stationeries (100.0%; predominant drug promotional method and information were in-person clinic encounter (100.0% and brand names of the drugs (100.0%, respectively. The most common source of drug information was calling a colleague/pharmacist (93.5% while 84.9% of the respondents were aware of code of regulation on drug promotion. The prescribing practice (P = 0.041 and attitude (P = 0.032 to drug promotion were significantly associated with working in public hospitals. Conclusion: Drug promotion by PSRs influenced prescribing practices of medical practitioners with 66.5% of them having positive attitude to drug promotion. The

  6. Finding Sales Promotion and Making Decision for New Product Based on Group Analysis of Edge-Enhanced Product Networks

    Science.gov (United States)

    Huang, Yi; Tan, Jianbin; Wu, Bin

    A novel method is proposed in this paper to find the promotive relationship of products from a network point of view. Firstly, a product network is built based on the dataset of handsets’ sale information collected from all outlets of a telecom operator of one province of China, with a period from Jan. 2006 to Jul. 2008. Then the edge enhanced model is applied on product network to divide all the products into several groups, according to which each outlet is assigned to class A or class B for a certain handset. Class A is defined as the outlet which sell the certain handset and contains all of handsets of its group, while other situation for class B which sell the certain handset too. It’s shown from the result of analysis on these two kinds of outlets that many handsets are sold better in outlets of class A than that of class B, even though the sales revenue of all these outlets in the time period is close. That is to say the handsets within a group would promote the sale for each other. Furthermore, a method proposed in this paper gives a way to find out the important attributes of the handsets which lead them to br divided into the same group, and it also explains how to add a new handset to an existing group and where would the new handset be sold best.

    2009-09-01

    Full Text Available Probiotics and prebiotics were compared to antimicrobials as alternative growth promoters in male broilers grown from 1 to 42 days of age. Eight treatments were evaluated: a control feed without antimicrobials or alternative growth promoters, a control feed with antimicrobials, a control feed with the antimicrobials colistine and avilamicine, three rations with probiotic Bacillus subtilis in different concentrations and/or under recommended usage, one ration with probiotic Saccharomyces cerevisiae in addition to a mixture of probiotic Bacillus subtilis, Saccharomyces cerevisiae and Aspergillus oryzae, and one ration with mananoligossacarids (MOS plus betaglutanes. Antimicrobials and alternative growth promoters were added to an initial feed and to a growth feed common to all birds. Thirteen to 17 replicates of 50 birds of a Cobb line were utilized per treatment in a completely randomized design. Feed consumption, feed conversion and production costs did not significantly differ among treatments. The weights of 42-day-old birds fed on Bacillus subtilis (1,6 x 109CFU/g or the mixture of probiotics were higher or similar to the weights of birds fed on ration with antimicrobials. It was concluded that probiotics can replace antimicrobials as growth promoters for broilers up to 42 days of age without negative effects on growth performance and production cost.

    The well-being of oncologists is important to the well-being of their patients. While much is known about oncologist distress, little is known about oncologist well-being. We set out to evaluate oncologist well-being and the personal wellness promotion strategies used by oncologists. We performed a cross-sectional survey of medical oncologists in the North Central Cancer Treatment Group using a validated instrument to measure quality of life. Study-specific questions explored stressors, wellness promotion strategies and career satisfaction. Of 241 responding oncologists (response rate 61%), 121 (50%) reported high overall well-being. Being age 50 or younger (57 vs. 41%; p = 0.01), male (53 vs. 31%; p = 0.01) and working 60 h or less per week (50 vs. 33%; p = 0.005) were associated with increased overall well-being on bivariate analysis. Ratings of the importance of a number of personal wellness promotion strategies differed for oncologists with high well-being compared with those without high well-being. Developing an approach/philosophy to dealing with death and end-of-life care, using recreation/hobbies/exercise, taking a positive outlook and incorporating a philosophy of balance between personal and professional life were all rated as substantially more important wellness strategies by oncologists with high well-being (p values career satisfaction. Half of medical oncologists experience high overall well-being. Use of specific personal wellness promotion strategies appears to be associated with oncologist well-being. Further investigations of the prevalence, promotion, causes, inequities and clinical impact of physician well-being are needed. .

    Women are under-represented in academia. Causative factors include challenges of career-family integration. We evaluated factors reflecting institutional culture (promotion, retention, hiring, and biasing language in promotion letters) as part of an intervention to help shift culture and raise awareness of flexibility policies at the University of California, Davis (UCD). Data on faculty use of family-friendly policies were obtained at baseline, and surveys for policy awareness were conducted pre(2010)/post(2013) an NIH-funded study educational intervention. Data on hires, separations, and promotions were obtained pre(2007-2009, 2234 person-year data points)/post(2010-2012, 2384 person-year data points) intervention and compared by logistic regression and for gender differences. Department promotion letters (53) were also analyzed for biasing language. Policy use was overall low, highest for female assistant professors, and for maternity leave. Awareness significantly increased for all policies postintervention. Promotions decreased, likely because of increases in advancement deferrals or tenure clock extensions. Pre/postintervention, female and male hires were near parity for assistant professors, but female hires were substantially lower than males for associate (54% less likely, p = 0.03) and full professors (70% less likely, p = 0.002). Once hired, women were no more likely to separate than men. Fewer associate/full professors separated than assistant professors (p = 0.002, p work-life flexibility, an environment in which letters of recommendation show very few biased descriptions, and in which assistant professor hiring is gender equitable. At the same time, a decrease in number of faculty members applying for promotion and an imbalance of men over women at senior hires independent of policy awareness may challenge the assumption that family-friendly policies, while promoting flexibility, also have a positive impact on professional advancement.

    The current food environment has a high prevalence of nutrient-sparse foods and beverages, most starkly seen in vending machine offerings. There are currently few studies that explore different interventions that might lead to healthier vending machine purchases. To examine how healthier product availability, price reductions, and/or promotional signs affect sales and revenue of snack and beverage vending machines. A 2×2×2 factorial randomized controlled trial was conducted. Students, staff, and employees on a university campus. All co-located snack and beverage vending machines (n=56, 28 snack and 28 beverage) were randomized into one of eight conditions: availability of healthier products and/or 25% price reduction for healthier items and/or promotional signs on machines. Aggregate sales and revenue data for the 5-month study period (February to June 2015) were compared with data from the same months 1 year prior. Analyses were conducted July 2015. The change in units sold and revenue between February through June 2014 and 2015. Linear regression models (main effects and interaction effects) and t test analyses were performed. The interaction between healthier product guidelines and promotional signs in snack vending machines documented increased revenue (Prevenue change. Price reductions alone had no effect, nor were there any effects for the three-way interaction of the factors. Examining top-selling products for all vending machines combined, pre- to postintervention, we found an overall shift to healthier purchasing. When healthier vending snacks are available, promotional signs are also important to ensure consumers purchase those items in greater amounts. Mitigating potential loss in profits is essential for sustainability of a healthier food environment. Copyright © 2017 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

    In this paper, we consider the application of the Lotka-Volterra model with churn effects, LVch, (Guidolin and Guseo, 2015) to the case of a confectionary product produced in Italy and recently commercialized in a European country. Weekly time series, referring separately to quantities of regular and promotional sales, are available. Their joint inspection highlighted the presence of compensatory dynamics suggesting the study with the LVch to estimate whether competition between regular and p...

    2014-09-15

    The use of mobile medical apps by clinicians and others has grown considerably since the introduction of mobile phones. Medical apps offer clinicians the ability to access medical knowledge and patient data at the point of care, but several studies have highlighted apps that could compromise patient safety and are potentially dangerous. This article identifies a range of different kinds of risks that medical apps can contribute to and important contextual variables that can modify these risks. We have also developed a simple generic risk framework that app users, developers, and other stakeholders can use to assess the likely risks posed by a specific app in a specific context. This should help app commissioners, developers, and users to manage risks and improve patient safety.

    Stathmin 1 (STMN1) is a biomarker in several types of neoplasms. It plays an important role in cell cycle progression, mitosis, signal transduction and cell migration. In ovaries, STMN1 is predominantly expressed in granulosa cells (GCs). However, little is known about the role of STMN1 in ovary. In this study, we demonstrated that STMN1 is overexpressed in GCs in patients with polycystic ovary syndrome (PCOS). In mouse primary GCs, the overexpression of STMN1 stimulated progesterone production, whereas knockdown of STMN1 decreased progesterone production. We also found that STMN1 positively regulates the expression of Star (steroidogenic acute regulatory protein) and Cyp11a1 (cytochrome P450 family 11 subfamily A member 1). Promoter and ChIP assays indicated that STMN1 increased the transcriptional activity of Star and Cyp11a1 by binding to their promoter regions. The data suggest that STMN1 mediates the progesterone production by modulating the promoter activity of Star and Cyp11a1. Together, our findings provide novel insights into the molecular mechanisms of STMN1 in ovary GC steroidogenesis. A better understanding of this potential interaction between STMN1 and Star in progesterone biosynthesis in GCs will facilitate the discovery of new therapeutic targets in PCOS.

    NCYM is a cis-antisense gene of MYCN and is amplified in human neuroblastomas. High NCYM expression is associated with poor prognoses, and the NCYM protein stabilizes MYCN to promote proliferation of neuroblastoma cells. However, the molecular mechanisms of NCYM in the regulation of cell survival have remained poorly characterized. Here we show that NCYM promotes cleavage of MYCN to produce the anti-apoptotic protein, Myc-nick, both in vitro and in vivo. NCYM and Myc-nick were induced at G2/M phase, and NCYM knockdown induced apoptotic cell death accompanied by Myc-nick downregulation. These results reveal a novel function of NCYM as a regulator of Myc-nick production in human neuroblastomas. - Highlights: • NCYM promotes cleavages of MYC and MYCN to produce Myc-nick in vitro. • NCYM increases Myc-nick production in MYCN-amplified neuroblastoma cells. • NCYM knockdown decreases Myc-nick production and induces apoptosis at G2/M phase.

    Knowledge co-production and boundary work offer planners a new frame for critically designing a social process that fosters collaborative implementation of resulting plans. Knowledge co-production involves stakeholders from diverse knowledge systems working iteratively toward common vision and action. Boundary work is a means of creating permeable knowledge boundaries that satisfy the needs of multiple social groups while guarding the functional integrity of contributing knowledge systems. Resulting products are boundary objects of mutual interest that maintain coherence across all knowledge boundaries. We examined how knowledge co-production and boundary work can bridge the gap between planning and implementation and promote cross-sectoral cooperation. We applied these concepts to well-established stages in regional conservation planning within a national scale conservation planning project aimed at identifying areas for conserving rivers and wetlands of South Africa and developing an institutional environment for promoting their conservation. Knowledge co-production occurred iteratively over 4 years in interactive stake-holder workshops that included co-development of national freshwater conservation goals and spatial data on freshwater biodiversity and local conservation feasibility; translation of goals into quantitative inputs that were used in Marxan to select draft priority conservation areas; review of draft priority areas; and packaging of resulting map products into an atlas and implementation manual to promote application of the priority area maps in 37 different decision-making contexts. Knowledge co-production stimulated dialogue and negotiation and built capacity for multi-scale implementation beyond the project. The resulting maps and information integrated diverse knowledge types of over 450 stakeholders and represented >1000 years of collective experience. The maps provided a consistent national source of information on priority conservation areas

  18. The role of electromagnetic separators in the production of radiotracers for bio-medical research and nuclear medical application

    2003-01-01

    With the growing complexity of positron emission tomography/single photon emission computed tomography imaging and the new developments in systemic radionuclide therapy there is a growing need for radioisotope preparations with higher radiochemical and radionuclidic purity that has not been achievable before. Especially important for the new applications is the specific activity of the radiotracer. Conventional methods in medical isotope production have reached their technical limitations. The role of isotope separators is discussed with examples of typical production and characterization experiments conducted at the ISOLDE and TRIUMF facilities. These preliminary experiments indicate that isotope separators have a definite role to play in the future for the production of radioisotopes for biomedical research and medical application.

    Palermo, Mariantonella; Fiore, Alberto; Fogliano, Vincenzo

    2012-10-10

    Soybeans are widely used in bakery products because of their technological advantages and, recently, soybean-containing products have been marketed as functional foods thanks to several health benefits. Okara is a soybean-based ingredient obtained after elimination of the water-soluble component from ground soybeans. In this paper the effect of okara addition to bakery products on the formation of some potentially harmful Maillard reaction products was evaluated. Cookies obtained by replacing 15% of wheat flour with okara showed a visible browning increase and a more intense Maillard reaction development as shown by higher concentrations of 5-hydroxymethyl-2-furaldehyde (HMF) (+100%), acrylamide (+60%), and carboxymethyl-lysine (CML) (+400%) with respect to the control. This phenomenon could be related to the presence in okara of about 50% of insoluble dietary fiber: the fiber reduces water activity during cooking, thus promoting Maillard reaction. To confirm this hypothesis, cookies obtained by replacing 7% of wheat flour with three different types of dietary fiber (cellulose, chitosan, and pea fiber) were prepared: these experimental cookies showed higher Maillard reaction product concentration with respect to the control and, in particular, HMF and CML values were directly related to the fiber water-holding capacity (WHC). To extend the observation to the food market, a sampling of soybean-containing commercial bakery products was analyzed by comparing the concentrations of Maillard reaction products with those of similar bakery products without soy. Soybean-containing samples showed higher concentrations of acrylamide and CML than corresponding controls.

    Preservatives are added to cosmetic, household cleaning, and other industrial products to prevent the growth of microorganisms. Unfortunately, exposure to these substances can cause sensitization. Between January and June 2015, we analyzed the ingredients of 2300 products commercially available in Spain to identify the frequency of a wide variety of preservatives in different product categories. We analyzed 1093 skin care and cosmetic products sold exclusively in pharmacies (dermocosmetics), 458 household cleaning and personal hygiene and cosmetic products sold in supermarkets, 636 topical medications, and 113 cosmetic products sold in a herbal shop. Phenoxyethanol, citric acid, sodium benzoate, and potassium sorbate were very common in all the cosmetic product categories. Parabens were present in 16.1% of dermocosmetic products, 14.45% of cosmetic products available in supermarkets, 0.88% of cosmetic products available in the herbal shop, 5.18% of topical medications, and in none of the cleaning products. Isothiazolinones were identified in 2.56% of dermocosmetic products, 18% of cosmetic products in supermarkets, 7.9% of cosmetic products in the herbal shop, 63.63% of household cleaners, and in none of the topical medications. Formaldehyde releasers were detected in 5.76% of dermocosmetic products, 6.42% of cosmetic products sold in supermarkets, 7.96% of cosmetic products sold in the herbal shop, 3.93% of topical medications, and 16.74% of household cleaners. Evaluation of the presence of preservatives in everyday products allows us to indirectly estimate exposure levels to each one. Measures restricting the use of the most problematic preservatives need to be strengthened. Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    Most primary care patients have at least 1 major behavioral risk: smoking, risky drinking, low physical activity, or unhealthy diet. We studied the effectiveness of a medical assistant-based program to identify and refer patients with risk behaviors to appropriate interventions. We undertook a randomized control trial in a practice-based research network. The trial included 864 adult patients from 6 primary care practices. Medical assistants screened patients for 4 risk behaviors and applied behavior-specific algorithms to link patients with interventions. Primary outcomes were improved risk behaviors on standardized assessments. Secondary outcomes included participation in a behavioral intervention and the program's effect on the medical assistants' workflow and job satisfaction. Follow-up data were available for 55% of participants at a mean of 12 months. The medical assistant referral arm referred a greater proportion of patients than did usual care (67.4 vs 21.8%; P effects on program adoption. Engaging more primary care team members to address risk behaviors improved referral rates. More extensive medical assistant training, changes in practice culture, and sustained behavioral interventions will be necessary to improve risk behavior outcomes.

  3. Do doctors benefit from their profession?--A survey of medical practitioners' health promotion and health safety practices.

    1998-12-01

    Three hundred Irish Medical Organisation members were surveyed on health promotion and health and safety issues. 64.7% responded (65.3 males; 33.7% < thirty-five years). Over half (54.9%) were aware of the safety legislation and very few reported available occupational health services. A majority wanted more such services. Nearly all believed health promotion was important yet only 35.2% always availed of opportunities to give such advice. 36.3% were often stressed, particularly at work. Alcohol was sometimes or frequently used to cope by around half of respondents. Although less than half (47.7%) used whole milk, one third usually or always added salt to their food. 15.5% took no weekly aerobic exercise but 42.0% claimed to do so three times weekly. 11.4 were current smokers. A third of women had never had a cervical smear. We conclude doctors require adequate occupational health services.

  4. Relevance and feasibility of women's involvement in promoting sustainable food production and security in Southern Africa

    Full Text Available Harnessing women’s potential for food production and security has been a challenge in Southern Africa. The face of food production in Southern Africa is often female, but more often than not, their roles are generally undervalued and constrained by gender inequalities and limitations on their access to resources, services, and market opportunities. This chapter explores how women involvement in food production can have a positive impact on food security in Southern Africa. The gender aspect of food security assume significance, as it is widely recognized that women are the custodian of food production in many communities in Southern Africa. There is a tendency of men and women participating unevenly in food production, have unequal access to productive resources and exhibit different levels of engagement in rural, urban and home-based food production. Despite this anomaly, there is still a common understanding that food production needs to be increased in order to cope with the increased human population and achieving food security in the region. With this in mind, food production and security have emerged as key development targets in Southern Africa. This has propelled the urgent need for promoting food production, reducing food insecurity and poverty reduction in its totality. One of the factors contributing to perpetual low food production and insecurity has been gender discrimination and/or lack of participation of women in agricultural programs and projects. In this chapter there is an attempt to describe the impact of gender-based discrimination on food production and its implication on food security. The indispensable role and challenges faced by women in food production are highlighted. The need to invest in education and training of women to support food production systems in order to accrue maximum benefit is acknowledged. In this regard, it is imperative that planning and implementation of any food production programs focusing on

    The reliable supply of molybdenum-99 ( 99 Mo) and its decay product, technetium-99m ( 99m Tc), is a vital component of modern medical diagnostic practices. At present, most of the global production of 99 Mo is from highly enriched uranium (HEU) targets. However, all major 99 Mo-producing countries have recently agreed to convert to using low-enriched uranium (LEU) targets to advance important non-proliferation goals, a decision that will have implications for the global supply chain of 99 Mo/ 99m Tc and the long-term supply reliability of these medical isotopes. This study provides the findings and analysis from an extensive examination of the 99 Mo/ 99m Tc supply chain by the OECD/NEA High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR). It presents a comprehensive evaluation of the potential impacts of converting to the use of LEU targets for 99 Mo production on the global 99 Mo/ 99m Tc market in terms of costs and available production capacity, and the corresponding implications for long-term supply reliability. In this context, the study also briefly discusses the need for policy action by governments in their efforts to ensure a stable and secure long-term supply of 99 Mo/ 99m Tc

    2003-01-01

    Relevant aspects on radiological protection for medical exposures are described taking into account the Spanish and European legal frameworks. Some specific topics will still require clarification or additional actions. The called special practices: exposures of children, health screening and high doses exposures to the patients need particular attention in the quality programmes. The need for coordination at local (Autonomous Communities), national and european level is highlighted. Safety and radiological protection aspects entail additional requirements to the quality programmes at the medical installations using ionizing radiations. Appropriate staffing and infrastructure are especially critical. Priorities from several international and european programmes and working groups are quoted. A proposal for actions to foster quality aspects in the medical exposures, with emphasis in resources, training and research is made. The impact of the introduction of digital radiology in the health system during the next years will require specific quality programmes to profit the advantages of this new technology.

  10. Predictors of Participation of Sophomore Medical Students in a Health-Promoting Intervention: An Observational Study.

    Directory of Open Access Journals (Sweden)

    Thomas Kötter

    Full Text Available Medical students and doctors have to be particularly stress-resilient, as both medical education and practice are considered very stressful. Specific stressors can lead to increased risks of developing, for example, depression, anxiety and burnout. Relaxation techniques have proven to be effective for the prevention of these outcomes in student populations. However, only a very few medical students practice relaxation techniques regularly early on in their studies. Furthermore, it is unclear which students make use of stress-management offers and hence whether vulnerable students are generally reachable. Therefore, the aim of our study was to explore predictors of participating in a voluntary stress management course for sophomore medical students. One cohort of freshmen at a German medical school was surveyed at the end of the freshman year [t1] and at the end of the sophomore year [t2]. In addition to sociodemographic information, we captured perceived study stress, self-rated general health and mental health and dimensions of study-related behaviour and experience as potential predictors of participation at t1. During the sophomore year, we offered the participants a progressive muscle relaxation (PMR beginners' course. At t2, we registered participation status. We used binary logistic regression analyses in order to assess correlations between potential predictors and participation. About one third of the whole class took part in the course. The main reason for non-participation was "no time". Being female and higher levels of anxiety were the strongest predictors of course participation. Career ambition (the higher, the less likely to participate and emotional distancing (the higher, the more likely to participate were further significant predictors. Future interventions should be attractive to both male and female medical students. Ideally, for every hour of stress management teaching, the curriculum should be cut by at least the same

    Even in health care systems corruption is an increasing problem. Since the German Anti-Corruption-Law (1997) the areas of financial support, sponsoring and corruption in medicine are analyzed much more intensively. This article sketches the crucial points of the debate on medical funding and shows the consequences of the new jurisdiction. Most important is the balance between a transparent documentation and a too-far-reaching bureaucracy, which hinders medical research. Finally, this article presents core principles as helpful rules in practice.

    Endothelial dysfunction is now well established as a pivotal early event in the development of major cardiovascular diseases including hypertension, atherosclerosis, and diabetes. The alteration of the endothelial function is often triggered by an imbalance between the endothelial formation of vasoprotective factors including nitric oxide (NO) and endothelium-dependent hyperpolarization, and an increased level of oxidative stress involving several prooxidant enzymes such as NADPH oxidase and, often also, the appearance of cyclooxygenase-derived vasoconstrictors. Preclinical studies have indicated that polyphenol-rich food and food-derived products such as grape-derived products, black and red berries, green and black teas and cocoa, and omega-3 fatty acids can trigger activating pathways in endothelial cells promoting an increased formation of nitric oxide and endothelium-dependent hyperpolarization. Moreover, intake of such food-derived products has been associated with the prevention and/or the improvement of an established endothelial dysfunction in several experimental models of cardiovascular diseases and in humans with cardiovascular diseases. This review will discuss both experimental and clinical evidences indicating that different types of food and natural products are able to promote endothelial and vascular health, as well as the underlying mechanisms.

    Evaluate the impact of a multicomponent workplace health promotion program on employee health risks and work productivity. Quasi-experimental 12-month before-after intervention-control study. A multinational corporation headquartered in the United Kingdom. Of 618 employees offered the program, 266 (43%) completed questionnaires before and after the program. A total of 1242 of 2500 (49.7%) of a control population also completed questionnaires 12 months apart. A multicomponent health promotion program incorporating a health risk appraisal questionnaire, access to a tailored health improvement web portal, wellness literature, and seminars and workshops focused upon identified wellness issues. Outcomes were (1) cumulative count of health risk factors and the World Health Organization health and work performance questionnaire measures of (2) workplace absenteeism and (3) work performance. After adjusting for baseline differences, improvements in all three outcomes were significantly greater in the intervention group compared with the control group. Mean excess reductions of 0.45 health risk factors and 0.36 monthly absenteeism days and a mean increase of 0.79 on the work performance scale were observed in the intervention group compared with the control group. The intervention yielded a positive return on investment, even using conservative assumptions about effect size estimation. The results suggest that a well-implemented multicomponent workplace health promotion program can produce sizeable changes in health risks and productivity.

    Full Text Available Background: In most cases, the work of medical doctors, be they general practitioners or specialists, involves some dimension of health promotion (HP. There is thus ample justification for increasing the awareness of medical students vis-à-vis HP and its relevance for their future practice.Methods: In the context of a major curriculum reform (problem-based learning [PBL] at the Faculty of Medicine of the University of Geneva in the mid-1990s, several steps were taken to strengthen HP throughout the curriculum and include HP in its key domains as defined by the Ottawa Charter (OC.Results: First, the political dimension of HP was developed in a series of first- and fifth-year lectures and third-year workshops; second, community action was strengthened through a third year one-month community immersion program; third, the development of personal skills was integrated into second- and third-year PBL cases and into fourth-and fifth-year learning activities in clinical settings as well as second- and third-year HP electives; in terms of reorienting health services, the chosen approach included the development of a HP-specific track in the context of a Certificate of Advanced Studies (CAS in Community Health and a Master of Advanced Studies(MAS in Public Health. Furthermore, a supportive intra-university environment was created through a collaborative convention with Health Promotion Switzerland, which is in charge of coordinating HP in Switzerland.Conclusion: In our view, HP teaching for medical students seems all the more relevant given that future medical doctors will have to take care of an increasing number of patients likely to develop chronic non-communicable diseases.

  16. Creating Structured Opportunities for Social Engagement to Promote Well-Being and Reduce Burnout in Medical Students and Residents.

    2017-12-26

    Increasing attention is being paid to medical student and resident well-being, as well as to enhancing resilience and avoiding burnout in medical trainees. Medical schools and residency programs are implementing wellness initiatives that often include meditation and other mindfulness activities, self-reflection, journaling, and lectures or workshops on resilience tools such as metacognition and cognitive restructuring. These interventions have in common the creation of opportunities for trainees to become more aware of their experiences, to better recognize stressors, and to regulate their thoughts and feelings so that stressors are less likely to have harmful effects. They often enable trainees to temporarily distance themselves mentally and emotionally from a stressful environment. In this Invited Commentary, the author suggests that medical school leaders and residency program directors should also create structured opportunities for trainees to establish meaningful connections with each other in order to provide greater social support and thereby reduce the harmful effects of stress. Social connection and engagement, as well as group identification, have potential to promote well-being and reduce burnout during training.

    Universities are increasingly organizing international exchange programs to meet the requirements of growing globalisation in the field of health care. Analyses based on the programs' fundamental theoretical background are needed to confirm the learning value for participants. This study investigated the extent of sociocultural learning in an exchange program and how sociocultural learning affects the acquisition of domain-specific competencies. Sociocultural learning theories were applied to study the learning effect for German medical students from the LMU Munich, Munich, Germany, of participation in the medical exchange program with Jimma University, Jimma, Ethiopia. First, we performed a qualitative study consisting of interviews with five of the first program participants. The results were used to develop a questionnaire for the subsequent, quantitative study, in which 29 program participants and 23 matched controls performed self-assessments of competencies as defined in the Tuning Project for Health Professionals. The two interrelated studies were combined to answer three different research questions. The participants rated their competence significantly higher than the control group in the fields of doctor-patient relationships and communication in a medical context. Participant responses in the two interrelated studies supported the link between the findings and the suggested theoretical background. Overall, we found that the exchange program affected the areas of doctor-patient relationships and effective communication in a medical context. Vygotsky's sociocultural learning theory contributed to explaining the learning mechanisms of the exchange program.

  1. Mode 2 Knowledge Production in the Context of Medical Research: A Call for Further Clarifications.

    2018-03-01

    The traditional researcher-driven environment of medical knowledge production is losing its dominance with the expansion of, for instance, community-based participatory or participant-led medical research. Over the past few decades, sociologists of science have debated a shift in the production of knowledge from traditional discipline-based (Mode 1) to more socially embedded and transdisciplinary frameworks (Mode 2). Recently, scholars have tried to show the relevance of Mode 2 knowledge production to medical research. However, the existing literature lacks detailed clarifications on how a model of Mode 2 knowledge production can be constructed in the context of medical research. This paper calls for such further clarifications. As a heuristic means, the advocacy for a controversial experimental stem cell therapy (Stamina) is examined. It is discussed that the example cannot be considered a step towards Mode 2 medical knowledge production. Nonetheless, the example brings to the fore some complexities of medical knowledge production that need to be further examined including: (1) the shifting landscape of defining and addressing vulnerability of research participants, (2) the emerging overlap between research and practice, and (3) public health implications of revising the standard notions of quality control and accountability.

    As studies continue to reveal favorable findings for the use of cannabidiol in the management of childhood epilepsy syndromes and other disorders, best practices for the large-scale production of Cannabis are needed for timely product development and research purposes. The processes of two institutions with extensive experience in producing large-scale cannabidiol chemotype Cannabis crops-GW Pharmaceuticals and the University of Mississippi-are described, including breeding, indoor and outdoor growing, harvesting, and extraction methods. Such practices have yielded desirable outcomes in Cannabis breeding and production: GW Pharmaceuticals has a collection of chemotypes dominant in any one of eight cannabinoids, two of which-cannabidiol and cannabidivarin-are supporting epilepsy clinical trial research, whereas in addition to a germplasm bank of high-THC, high-CBD, and intermediate type cannabis varieties, the team at University of Mississippi has established an in vitro propagation protocol for cannabis with no detectable variations in morphologic, physiologic, biochemical, and genetic profiles as compared to the mother plants. Improvements in phytocannabinoid yields and growing efficiency are expected as research continues at these institutions. This article is part of a Special Issue entitled "Cannabinoids and Epilepsy".

  9. Fine tuning of the lactate and diacetyl production through promoter engineering in Lactococcus lactis.

    Directory of Open Access Journals (Sweden)

    Tingting Guo

    Full Text Available Lactococcus lactis is a well-studied bacterium widely used in dairy fermentation and capable of producing metabolites with organoleptic and nutritional characteristics. For fine tuning of the distribution of glycolytic flux at the pyruvate branch from lactate to diacetyl and balancing the production of the two metabolites under aerobic conditions, a constitutive promoter library was constructed by randomizing the promoter sequence of the H(2O-forming NADH oxidase gene in L. lactis. The library consisted of 30 promoters covering a wide range of activities from 7,000 to 380,000 relative fluorescence units using a green fluorescent protein as reporter. Eleven typical promoters of the library were selected for the constitutive expression of the H(2O-forming NADH oxidase gene in L. lactis, and the NADH oxidase activity increased from 9.43 to 58.17-fold of the wild-type strain in small steps of activity change under aerobic conditions. Meanwhile, the lactate yield decreased from 21.15 ± 0.08 mM to 9.94 ± 0.07 mM, and the corresponding diacetyl production increased from 1.07 ± 0.03 mM to 4.16 ± 0.06 mM with the intracellular NADH/NAD(+ ratios varying from 0.711 ± 0.005 to 0.383 ± 0.003. The results indicated that the reduced pyruvate to lactate flux was rerouted to the diacetyl with an almost linear flux variation via altered NADH/NAD(+ ratios. Therefore, we provided a novel strategy to precisely control the pyruvate distribution for fine tuning of the lactate and diacetyl production through promoter engineering in L. lactis. Interestingly, the increased H(2O-forming NADH oxidase activity led to 76.95% lower H(2O(2 concentration in the recombinant strain than that of the wild-type strain after 24 h of aerated cultivation. The viable cells were significantly elevated by four orders of magnitude within 28 days of storage at 4°C, suggesting that the increased enzyme activity could eliminate H(2O(2 accumulation and prolong cell survival.

    Plant growth promoting rhizobacteria increase plant growth and give protection against insect pests and pathogens. Due to the negative impact of chemical pesticides on environment, alternatives to these chemicals are needed. In this scenario, the biological methods of pest control offer an eco-friendly and an attractive option. In this study, the effect of two plant growth promoting rhizobacterial strains (Bacillus sp. strain 6 and Pseudomonas sp. strain 6K) on aphid population and wheat productivity was evaluated in an aphid susceptible (Pasban-90) and resistant (Inqlab-91) wheat cultivar. The seeds were inoculated with each PGPR strain, separately or the combination of both. The lowest aphid population (2.1tiller -1 ), and highest plant height (85.8cm), number of spikelets per spike (18), grains per spike (44), productive tillers (320m -2 ), straw yield (8.6Mgha -1 ), and grain yield (4.8Mgha -1 ) were achieved when seeds were inoculated with Bacillus sp. strain 6+Pseudomonas sp. strain 6K. The grain yield of both varieties was enhanced by 35.5-38.9% with seed inoculation with both bacterial strains. Thus, the combine use of both PGPR strains viz. Bacillus sp. strain 6+Pseudomonas sp. strain 6K offers an attractive option to reduce aphid population tied with better wheat productivity. Copyright © 2018 Sociedade Brasileira de Microbiologia.

    WHERE DO WE STAND NOW?: In the 30 years that have passed since The Edinburgh Declaration on Medical Education, we have made tremendous progress in research on fostering 'self-directed and independent study' as propagated in this declaration, of which one prime example is research carried out on problem-based learning. However, a large portion of medical education happens outside of classrooms, in authentic clinical contexts. Therefore, this article discusses recent developments in research regarding fostering active learning in clinical contexts. Clinical contexts are much more complex and flexible than classrooms, and therefore require a modified approach when fostering active learning. Recent efforts have been increasingly focused on understanding the more complex subject of supporting active learning in clinical contexts. One way of doing this is by using theory regarding self-regulated learning (SRL), as well as situated learning, workplace affordances, self-determination theory and achievement goal theory. Combining these different perspectives provides a holistic view of active learning in clinical contexts. ENTRY TO PRACTICE, VOCATIONAL TRAINING AND CONTINUING PROFESSIONAL DEVELOPMENT: Research on SRL in clinical contexts has mostly focused on the undergraduate setting, showing that active learning in clinical contexts requires not only proficiency in metacognition and SRL, but also in reactive, opportunistic learning. These studies have also made us aware of the large influence one's social environment has on SRL, the importance of professional relationships for learners, and the role of identity development in learning in clinical contexts. Additionally, research regarding postgraduate lifelong learning also highlights the importance of learners interacting about learning in clinical contexts, as well as the difficulties that clinical contexts may pose for lifelong learning. However, stimulating self-regulated learning in undergraduate medical education

    Over 3000 cancer patients have already been treated by the heavy-ion medical accelerator in Chiba at the National Institute of Radiological Sciences since 1994. The clinical results have clearly verified the effectiveness and safety of heavy-ion radiotherapy. The most important result has been to establish that the carbon ion is one of the most effective radiations for radiotherapy. The ion source is required to realize a stable beam with the same conditions for daily operation. However, the deposition of carbon ions on the wall of the plasma chamber is normally unavoidable. This causes an ''anti-wall-coating effect,'' i.e., a decreasing of the beam, especially for the higher charge-state ions due to the surface material of the wall. The ion source must be required to produce a sufficiently intense beam under the bad condition. Other problems were solved by improvements and maintenance, and thus we obtained enough reproducibility and stability along with decreased failures. We summarize our over 13 years of experience, and show the scope for further developments

    Promoters are essential on plasmid vectors to initiate transcription of the transgenes when generating therapeutic recombinant proteins expressing mammalian cell lines. High and sustained levels of gene expression are desired during therapeutic protein production while gene expression is useful for cell engineering. As many finely controlled promoters exhibit cell and product specificity, new promoters need to be identified, optimized and carefully evaluated before use. Suitable promoters can be identified using techniques ranging from simple molecular biology methods to modern high-throughput omics screenings. Promoter engineering is often required after identification to either obtain high and sustained expression or to provide a wider range of gene expression. This review discusses some of the available methods to identify and engineer promoters for therapeutic recombinant protein expression in mammalian cells.

    The report presents results of surveillance of 1836 workers of beryllium production of Ulba Metallurgical Plant JSC with the acute and chronic forms of occupation diseases for 52 years of its operation. The dependence of acute and chronic occupation lesions on the protection degree is shown. It has been found out that, the risk of getting an occupation disease increases sharply at the moments of experimental works and at the time of reconstruction and some other extreme conditions in the production, that is supported by fixed lesions of eye mucous coat, skin and lung lesions. In this case, the readiness of people for their work in deleterious conditions and their personal responsibility for following the regulations of safety occupational standards plays a definite role. Therefore, the issues of protection are of paramount importance in prophylaxis both of acute and chronic exposure to beryllium. An influence of duration of service and occupation on chronic beryllium diseases is shown. A parallel between the lung beryllium disease and skin lesions by insoluble beryllium compounds is drawn for the first time. (author)

    Chinese medical universities typically have a high number of students, a shortage of teachers and limited equipment, and as such histology courses have been taught using traditional lecture-based formats, with textbooks and conventional microscopy. This method, however, has reduced creativity and problem-solving skills training in the curriculum. The virtual microscope (VM) system has been shown to be an effective and efficient educational strategy. The present study aims to describe a VM system for undergraduates and to evaluate the effects of promoting active learning and problem-solving skills. Two hundred and twenty-nine second-year undergraduate students in the Third Military Medical University were divided into two groups. The VM group contained 115 students and was taught using the VM system. The light microscope (LM) group consisted of 114 students and was taught using the LM system. Post-teaching performances were assessed by multiple-choice questions, short essay questions, case analysis questions and the identification of structure of tissue. Students' teaching preferences and satisfaction were assessed using questionnaires. Test scores in the VM group showed a significant improvement compared with those in the LM group (p 0.05); however, there were notable differences in the mean score rate of case analysis questions and identification of structure of tissue (p effects of the VM system in terms of additional learning resources, critical thinking, ease of communication and confidence. The VM system is an effective tool at Chinese medical university to promote undergraduates' active learning and problem-solving skills as an assisted teaching platform.

    The possibilities of 123 I production with small accelerators are discussed. Among the possible nuclear reactions the 122 Te(d,n) 123 I and the 123 Te(p,n) 123 I reaction are of particular interest for those institutions, who do not run a cyclotron with particle energies for protons above 18-20 MeV. The use of TeO 2 as target material is advantaged over Te. The 123 I preparations contain resonable amounts of 130 I and 124 I. The most 'dangerous' impurity is 130 I due to its high energy gamma radiation. Nevertheless, high quality imagings may be obtained using medium or high energy collimators loosing some of the advantages of 123 I. The proposed approach is the only way to make 123 I available for a number of institutions or countries running small cyclotrons and for which commercial 123 I is difficult or impossible to obtain for economical or geographical reasons.

  3. Production of phytotoxic cationic α-helical antimicrobial peptides in plant cells using inducible promoters.

    Directory of Open Access Journals (Sweden)

    Nuri Company

    Full Text Available Synthetic linear antimicrobial peptides with cationic α-helical structures, such as BP100, have potent and specific activities against economically important plant pathogenic bacteria. They are also recognized as valuable therapeutics and preservatives. However, highly active BP100 derivatives are often phytotoxic when expressed at high levels as recombinant peptides in plants. Here we demonstrate that production of recombinant phytotoxic peptides in transgenic plants is possible by strictly limiting transgene expression to certain tissues and conditions, and specifically that minimization of this expression during transformation and regeneration of transgenic plants is essential to obtain viable plant biofactories. On the basis of whole-genome transcriptomic data available online, we identified the Os.hsp82 promoter that fulfilled this requirement and was highly induced in response to heat shock. Using this strategy, we generated transgenic rice lines producing moderate yields of severely phytotoxic BP100 derivatives on exposure to high temperature. In addition, a threshold for gene expression in selected tissues and stages was experimentally established, below which the corresponding promoters should be suitable for driving the expression of recombinant phytotoxic proteins in genetically modified plants. In view of the growing transcriptomics data available, this approach is of interest to assist promoter selection for specific purposes.

    Radioisotopes are produced by using a low power research reactor, TRIGA MARK II situated at UTN. Products intended for use as radiopharmaceuticals undergo a more stringent precaution. The solvent extraction technique used to separate 99 m TC from the radioactive solution of Potassium molybdate (K 2 99 Mo0 4 ) is explained in detail. The specific activity of 99Mo obtained at a neutron flux of 2.5 x 10 12 n/cm 2 , s ranges from 1.75 mCi 99 Mo/g MoO 3 to 6.25 mCi 99 Mo/g MoO 3 . However, the specific activity of 99 Mo obtained could be increased by a factor of 6 using the central thimble facility. There are 14 radioisotopes being currently produced. Commonly used cold kits for 99m TC labelling are also produced. Sn-MDP kit for bone scintigraphy is prepared under aseptic environment and freeze-drived. Products are terminally sterilized using γ-irradiation. Uptake studies done on laboratory animals indicate good bone uptake. A few radioisotopes and radiopharmaceuticals products to be produced by UTN in future are reviewed. (author)

    expression in the brain was higher in CONV-R versus GF mice. We also observed that colonic Insl5 expression was suppressed by increasing the energy supply in GF mice by colonization or high-fat feeding. We did not observe any differences in food intake, gut transit or oral glucose tolerance between Insl5......-/- and wild-type mice. However, we showed impaired intraperitoneal glucose tolerance in Insl5-/- mice. We also observed improved insulin tolerance and reduced hepatic glucose production in Insl5-/- mice. CONCLUSIONS: We have shown that colonic Insl5 expression is regulated by the gut microbiota and energy...... availability. We propose that INSL5 is a hormone that could play a role in promoting hepatic glucose production during periods of energy deprivation....

    Rabbit polyclonal antisera against indoleacetic acid (IAA) bound to nitrocellulose membrane were obtained, which exhibited a high titer and specificity. The dot immunobinding technique with colloidal gold was used to detect auxin production by several strains belonging to Gluconacetobacter, Herbaspirillum, Azospirillum, Pseudomonas, Burkholderia and Bacillus genera, using culture supernatants as antigens. Moreover, auxin production was quantified by the Salkowski's method to corroborate the previous results. It was found that that all the studied microorganisms produce IAA and the feasibility of using these antisera to detect the metabolite was confirmed. Taking into account the potentialities of plant growth promoting bacteria as biofertilizers, the use of these antisera for a rapid and easy detection of IAA in bacteria associated with important crops is thus recommended.

    Patients' transition between hospital and community is a high-risk period for the occurrence of medication-related problems. The objective was to review initiatives, implemented at national and regional levels in seven selected countries, aiming at improving continuity in medication management upon admission and hospital discharge. We performed a structured search of grey literature, mainly through relevant websites (scientific, professional and governmental organizations). Regional or national initiatives were selected. For each initiative data on the characteristics, impact, success factors and barriers were extracted. National experts were asked to validate the initiatives identified and the data extracted. Most initiatives have been implemented since the early 2000 and are still ongoing. The principal actions include: development and implementation of guidelines for healthcare professionals, national information campaigns, education of healthcare professionals and development of information technologies to share data across settings of care. Positive results have been partially reported in terms of intake into practice or process measures. Critical success factors identified included: leadership and commitment to convey national and local forces, tailoring to local settings, development of a regulatory framework and information technology support. Barriers identified included: lack of human and financial resources, questions relative to responsibility and accountability, lack of training and lack of agreement on privacy issues. Although not all initiatives are applicable as such to a particular healthcare setting, most of them convey very interesting data that should be used when drawing recommendations and implementing approaches to optimize continuity of care.

    A method for production of carrier free 123 I with high radionuclidic purity in which the processing is done remotely was developed at Instituto de Engenharia Nuclear in Rio de Janeiro. The 123 I is produced in the decay of 123 Xe which is obtained through the reaction 122 Te ( 3 He, 2 n) 123 Xe with 30 MeV 3 He beams of IEN's variable energy cyclotron. The irradiated natural Te O 2 target is heated in a furnace at 675 0 C and the diffused out 123 Xe is adsorbed in a copper trap maintained at -196 0 C. The 123 Xe is allowed to decay during 6.3 hours and the 123 I produced washed out of the trap with a 0.1 N solution of NaOH. All the process is remotely controlled by using electric and pneumatic systems as well as manipulators and tongs. The quality control was achieved by atomic absorption and gamma-ray spectroscopy.

    The fundamental concept for sterilization is generally to bring the objects into the condition that less than one microorganism can grow in 10 6 products. Therefore required dose differs according to the selection of indexing microorganism. In the U.K., approximately 2.5 Mrad is adopted by employing methylmethacrylate (trade name Perspex) as the standard dosimeter. Japan has no legally controlled sterilization dose, but 2.5 Mrad in adopted in irradiation plants. In Japan, plants for the germination suppression of potatos and onions have been operated, the permitted dose being 15 krad. It is legal obligation to measure dose, and presently Fricke dosimeter is used, though it has some problems. As for rice and wheat sterilization, also Fricke dosimeter meets the requirements for the package forms of box or bag, but problems arise in bulk treatment at silo type equipments. Considering future expansion of application, the following developments may be necessary: dosimeters for 10--50 krad, dosimeters for 0.1 to 0.5 Mrad measurement being able to be handled similarly to Fricke or Perspex dosimeter, and measuring method for absorbed dose of electron beam.

    In vitro gluconic acid formation and phosphate solubilization from sparingly soluble phosphorus sources by two strains of the plant growth-promoting bacteria A. brasilense (Cd and 8-I) and one strain of A. lipoferum JA4 were studied. Strains of A. brasilense were capable of producing gluconic acid when grown in sparingly soluble calcium phosphate medium when their usual fructose carbon source is amended with glucose. At the same time, there is a reduction in pH of the medium and release of soluble phosphate. To a greater extent, gluconic acid production and pH reduction were observed for A. lipoferum JA4. For the three strains, clearing halos were detected on solid medium plates with calcium phosphate. This is the first report of in vitro gluconic acid production and direct phosphate solubilization by A. brasilense and the first report of P solubilization by A. lipoferum. This adds to the very broad spectrum of plant growth-promoting abilities of this genus.

    Concept mapping is an effective method in teaching and learning, however this strategy has not been evaluated among electrocardiogram (ECG) diagnosis learning. This study explored the use of concept maps to assist ECG study, and sought to analyze whether this method could improve undergraduate students’ ECG interpretation skills. There were 126 undergraduate medical students who were randomly selected and assigned to two groups, group A (n = 63) and group B (n = 63). Group A was taught to use concept maps to learn ECG diagnosis, while group B was taught by traditional methods. After the course, all of the students were assessed by having an ECG diagnostic test. Quantitative data which comprised test score and ECG features completion index was compared by using the unpaired Student’s t-test between the two groups. Further, a feedback questionnaire on concept maps used was also completed by group A, comments were evaluated by a five-point Likert scale. The test scores of ECGs interpretation was 7.36 ± 1.23 in Group A and 6.12 ± 1.39 in Group B. A significant advantage (P = 0.018) of concept maps was observed in ECG interpretation accuracy. No difference in the average ECG features completion index was observed between Group A (66.75 ± 15.35%) and Group B (62.93 ± 13.17%). According qualitative analysis, majority of students accepted concept maps as a helpful tool. Difficult to learn at the beginning and time consuming are the two problems in using this method, nevertheless most of the students indicated to continue using it. Concept maps could be a useful pedagogical tool in enhancing undergraduate medical students’ ECG interpretation skills. Furthermore, students indicated a positive attitude to it, and perceived it as a resource for learning. PMID:26221331

    The goal of this literature review was to determine communication strategies that foster interactions between individuals with Alzheimer's disease (AD) and caregivers or medical staff. A search of PubMed and PsycINFO databases was conducted using combinations of the following terms: Alzheimer, family, caregiver, communication, language, treatment, intervention, therapy, communication strategies, functional communication and daily living activities. Studies were chosen based on the original language of the text, year of publication, peer-review status and specificity of the results regarding communication strategies in AD. This review covers 14 articles published between 1994 and 2014. The in-depth analysis of these studies shows that various communication strategies used by caregivers and medical staff are effective to promote interactions with people with AD at different stages of the disease. For caregivers, these strategies include producing short and syntactically simple sentences, relying on semantic memory rather than on episodic memory, providing more information and reformulate, removing potential distractions from the environment, specifying the topic of the conversation, using precise terms to identify communication breakdowns. Other strategies also appeared to be effective for medical staff, such as asking close-ended questions, providing response choices, verbalizing the actions performed during medical care and activities, paying attention to the needs expressed through verbal and non-verbal messages, adopting a supportive way of speaking. Furthermore, other communication strategies rather appear to be harmful to functional communication. These harmful strategies involve insisting that the person produce a specific word, asking him/her to repeat or tune out in case of communication breakdown. Finally, contradictory outcomes are reported for some strategies such as speaking slowly, repeating or rephrase questions and information. This article provides

    This exploratory study describes the experiences arising from exposure to extreme summer heat, and the related health protection and promotion issues for working people in Australia. Twenty key informants representing different industry types and occupational groups or activities in Australia provided semi-structured interviews concerning: (i) perceptions of workplace heat exposure in the industry they represented, (ii) reported impacts on health and productivity, as well as (iii) actions taken to reduce exposure or effects of environmental heat exposure. All interviewees reported that excessive heat exposure presents a significant challenge for their industry or activity. People working in physically demanding jobs in temperatures>35°C frequently develop symptoms, and working beyond heat tolerance is common. To avoid potentially dangerous health impacts they must either slow down or change their work habits. Such health-preserving actions result in lost work capacity. Approximately one-third of baseline work productivity can be lost in physically demanding jobs when working at 40°C. Employers and workers consider that heat exposure is a 'natural hazard' in Australia that cannot easily be avoided and so must be accommodated or managed. Among participants in this study, the locus of responsibility for coping with heat lay with the individual, rather than the employer. Heat exposure during Australian summers commonly results in adverse health effects and productivity losses, although quantification studies are lacking. Lack of understanding of the hazardous nature of heat exposure exacerbates the serious risk of heat stress, as entrenched attitudinal barriers hamper amelioration or effective management of this increasing occupational health threat. Educational programmes and workplace heat guidelines are required. Without intervention, climate change in hot countries, such as Australia, can be expected to further exacerbate heat-related burden of disease and loss

    A growing global concern of antibiotic use in poultry diets due to its potential adverse effects on birds and human health, food safety and the environment has led to a complete ban or restricted use in some countries, and, at the same time, expanding options for the use of alternative feed additives. Multiple, rather than a single additive may replace antibiotic growth promoters (AGPs) in poultry. Blending of feeding additives and hygienic farm management, vaccination and biosecurity may help achieve good intestinal health, stabilise enteric ecosystems and result in sustainable and cost effective production performance of birds. Moreover, controlling unsolicited ingredients at the production level must have the support of different markets responsible for the supply of safe and quality poultry products for consumers. This requires the further increase and diversification of value added poultry products and the expansion of their markets through strategic planning and gradual limitation of live bird markets. More research is warranted in order to explore suitable, reliable and cost effective alternatives to AGPs for commercial use, and strategic poultry value chain development.

    Wound healing is a natural process of body reaction to repair itself after injury. Nonetheless, many internal and external factors such as aging, comorbidity, stress, smoking, alcohol drinking, infections, malnutrition, or wound environment significantly affect the quality and speed of wound healing. The unsuitable conditions may delay wound healing process and cause chronic wound or scar formation. Therefore, many researches have attempted to search for agents that can accelerate wound healing with safety and biocompatibility to human body. Widely studied wound healing agents are those derived from either natural sources including plants and animals or chemical synthesis. The natural products seem to be safer and more biocompatible to human tissue. This review paper demonstrated various kinds of the animal-derived products including chitosan, collagen, honey, anabolic steroids, silk sericin, peptides, and proteoglycan in term of mechanisms of action, advantages, and disadvantages when applied as wound healing accelerator. The benefits of these animal-derived products are wound healing promotion, anti-inflammatory, antimicrobial activity, moisturizing effect, biocompatibility, and safety. However, the drawbacks such as allergy, low stability, batch-to-batch variability, and high extraction and purification costs could not be avoided in some products.

    Macrophages play a crucial role in host innate anti-mycobacterial defense, which is tightly regulated by multiple factors, including microRNAs. Our previous study showed that a panel of microRNAs was markedly up-regulated in macrophages upon mycobacterial infection. Here, we investigated the biological function of miR-146a during mycobacterial infection. miR-146a expression was induced both in vitro and in vivo after Mycobacterium bovis BCG infection. The inducible miR-146a could suppress the inducible nitric oxide (NO) synthase (iNOS) expression and NO generation, thus promoting mycobacterial survival in macrophages. Inhibition of endogenous miR-146a increased NO production and mycobacterial clearance. Moreover, miR-146a attenuated the activation of nuclear factor κB and mitogen-activated protein kinases signaling pathways during BCG infection, which in turn repressed iNOS expression. Mechanistically, miR-146a directly targeted tumor necrosis factor (TNF) receptor-associated factor 6 (TRAF6) at post-transcriptional level. Silencing TRAF6 decreased iNOS expression and NO production in BCG-infected macrophages, while overexpression of TRAF6 reversed miR-146a-mediated inhibition of NO production and clearance of mycobacteria. Therefore, we demonstrated a novel role of miR-146a in the modulation of host defense against mycobacterial infection by repressing NO production via targeting TRAF6, which may provide a promising therapeutic target for tuberculosis.

    Product-line administration is a viable approach for managing medical records services in an environment that demands high quantity and quality service levels. Product-line administration directs medical record department team members to look outside of the department and seek input from the customers it is intended to serve. The feedback received may be alarming at first, as the current state of products usually reveals a true lack of customer input. As the planning, defining, managing, and marketing phases are implemented, the road will not be easy and rewards will be slow to come. Product-line administration does not provide quick fixes, but it does provide long-term problem resolution as products are refined and new products developed to meet customer needs and expectations. In addition to better meeting the needs of the department's external customers, the department's internal customers' needs and expectations will be addressed. The participative management approach will help nurture each team member's creativity. The team members will have the opportunity to reach their full potential while reaping the rewards and benefits of providing products and services that meet the needs and expectations of all department customers. The future of the health care industry promises more changes as the country moves toward some form of prospective payment in the ambulatory setting. Reactive management and the constant struggle to catch up can no longer be accepted as a management approach. It is imperative that the medical record department be viewed as a business with product lines composed of quality products. The planning, defining, managing, and marketing components of product-line administration afford responsiveness to the current situation and the development of quality products that will ensure that medical record departments are prepared for the future.

    The German government intends to reduce the barriers for the medical use of cannabis products. A discussion on the indications and contraindications of the medical use of cannabis and on the changes of the regulatory framework has already begun in Germany. It is useful to draw from the experiences of other countries with a more liberal medical use of cannabis. The Israeli and Canadian experience is outlined by physicians who have been charged with expertise on the medical use of cannabis by their jurisdiction. In Israel, only the plant-based cannabinoid nabiximol (mixture of tetrahydrocannabinol/cannabidiol) can be prescribed for spasticity/chronic pain in multiple sclerosis and for cancer pain. The costs of nabiximole are reimbursed by some, but not by all health maintenance organizations. The medical use of marijuana is permitted; however, it is strictly regulated by the government. Selected companies are allowed to produce marijuana for medical use, and only certain physicians are licensed to prescribe marijuana as a therapeutic drug for specific indications such as chronic neuropathic, and cancer pain, inflammatory bowel diseases, or posttraumatic stress disorder if conventional treatments have failed. The costs of marijuana are not reimbursed by health insurance companies. In Canada, synthetic cannabinoids and the plant-based (nabiximol) are licensed for neuropathic and cancer pain, HIV-related anorexia and chemotherapy-associate nausea. The costs of these synthetic cannabinoids are covered by health insurance companies. The medical use of marijuana as a treatment option is allowed for individual patients suffering from any medical condition when authorized by a medical practitioner or nurse. Licensed producers are the only source for patients to newly access medical cannabis, although those with previous permission to grow may continue cultivation at the present time. The costs of marijuana are not reimbursed by health insurance companies. There are multiple

    In the actual economic context, with increasing health needs, efficiency and efficacy represents fundamental keyword to ensure a successful use of the resources and the best health outcomes. Together, the medical record, completely and correctly compiled, is an essential tool in the patient diagnostic and therapeutic path, but it's becoming more and more essential for the administrative reporting and legal claims. Nevertheless, even if the improvement of medical records quality and of hospital stay appropriateness represent priorities for every health organization, they could be difficult to realize. This study aims to present the methodology and the preliminary results of a training and improvement process: it was carried out from the Hospital Management of a third level Italian teaching hospital through audit cycles to actively involve their health professionals. A self assessment process of medical records quality and hospital stay appropriateness (inpatients admission and Day Hospital) was conducted through a retrospective evaluation of medical records. It started in 2012 and a random sample of 2295 medical records was examined: the quality assessment was performed using a 48-item evaluation grid modified from the Lombardy Region manual of the medical record, while the appropriateness of each days was assessed using the Italian version of Appropriateness Evaluation Protocol (AEP) - 2002ed. The overall assessment was presented through departmental audit: the audit were designed according to the indication given by the Italian and English Ministry of Health to share the methodology and the results with all the involved professionals (doctors and nurses) and to implement improvement strategies that are synthesized in this paper. Results from quality and appropriateness assessment show several deficiencies, due to 40% of minimum level of acceptability not completely satisfied and to 30% of inappropriateness between days of hospitalization.

    Full text: The lessons learned from several radiological accidents in medical and industrial practices using sources of ionization radiation show that a fragile safety culture in the organizations and the human error were the most important contributors to such events. The high contribution of human factors to safety of radiotherapy treatment process have been also revealed by the results of a recent study on Probabilistic Safety Assessment to this process conducted in the framework of the Extra budgetary Programme on Nuclear and Radiological Safety in Iberian-America. Nevertheless non considerable efforts are appreciated around the world to investigate and develop methods and techniques to assess and promote a strong safety culture in those practices as it has been happening in other sectors like nuclear power, chemical, commercial aviation and oil industry. The Cuban Nuclear Regulatory Authority has in course a National Program for Promoting and Assessment of Safety Culture in organizations using sources of ionizing radiation. As part of this program, during the 2007 year, a pilot study with this purpose was carried out Two Radiotherapy and Nuclear Medicine Units were selected for this pilot study, where managers and specialists were interviewed, a safety culture survey was executed and a final report was prepared with several recommendations to be taking account by Regulator for designing its regulatory strategy on safety culture for medical practices and by users to increase their safety culture level. This paper describes the methodology used to organize, prepare, execute and report the results, findings and recommendations of this kind of review, the benefits and main difficulties encountered during this effort and the perspective and suggestions that, in opinion of the authors of this paper, are important to take into account in the field of radiological safety culture in the near future.

    The goal of this LDRD project was to demonstrate the technical and economical feasibility of applying laser isotope separation technology to the commercial enrichment (>lkg/y) of stable isotopes. A successful demonstration would well position the laboratory to make a credible case for the creation of an ongoing medical and industrial isotope production and development program at LLNL. Such a program would establish LLNL as a center for advanced medical isotope production, successfully leveraging previous LLNL Research and Development hardware, facilities, and knowledge

    Full Text Available Communication success under adverse conditions requires efficient and effective recruitment of both bottom-up (sensori-perceptual and top-down (cognitive-linguistic resources to decode the intended auditory-verbal message. Employing these limited capacity resources has been shown to vary across the lifespan, with evidence indicating that younger adults out-perform older adults for both comprehension and memory of the message. This study examined how sources of interference arising from the speaker (message spoken with conversational versus clear speech technique, the listener (hearing-listening and cognitive-linguistic factors, and the environment (in competing speech babble noise versus quiet interact and influence learning and memory performance using more ecologically valid methods than has been done previously. The results suggest that when older adults listened to complex medical prescription instructions with ‘clear speech,’ (presented at audible levels through insertion earphones their learning efficiency, immediate and delayed memory performance improved relative to their performance when they listened with a normal conversational speech rate (presented at audible levels in sound field. This better learning and memory performance for clear speech listening was maintained even in the presence of speech babble noise. The finding that there was the largest learning-practice effect on 2nd trial performance in the conversational speech when the clear speech listening condition was first is suggestive of greater experience-dependent perceptual learning or adaptation to the speaker’s speech and voice pattern in clear speech. This suggests that experience-dependent perceptual learning plays a role in facilitating the language processing and comprehension of a message and subsequent memory encoding.

    Communication success under adverse conditions requires efficient and effective recruitment of both bottom-up (sensori-perceptual) and top-down (cognitive-linguistic) resources to decode the intended auditory-verbal message. Employing these limited capacity resources has been shown to vary across the lifespan, with evidence indicating that younger adults out-perform older adults for both comprehension and memory of the message. This study examined how sources of interference arising from the speaker (message spoken with conversational vs. clear speech technique), the listener (hearing-listening and cognitive-linguistic factors), and the environment (in competing speech babble noise vs. quiet) interact and influence learning and memory performance using more ecologically valid methods than has been done previously. The results suggest that when older adults listened to complex medical prescription instructions with “clear speech,” (presented at audible levels through insertion earphones) their learning efficiency, immediate, and delayed memory performance improved relative to their performance when they listened with a normal conversational speech rate (presented at audible levels in sound field). This better learning and memory performance for clear speech listening was maintained even in the presence of speech babble noise. The finding that there was the largest learning-practice effect on 2nd trial performance in the conversational speech when the clear speech listening condition was first is suggestive of greater experience-dependent perceptual learning or adaptation to the speaker's speech and voice pattern in clear speech. This suggests that experience-dependent perceptual learning plays a role in facilitating the language processing and comprehension of a message and subsequent memory encoding. PMID:26106353

    New dissemination methods are needed to engage physicians in evidence-based continuing medical education (CME). To examine the effectiveness of social media in engaging physicians in non-industry-sponsored CME. We tested the effect of different media platforms (e-mail, Facebook, paid Facebook and Twitter), CME topics, and different "hooks" (e.g., Q&A, clinical pearl and best evidence) on driving clicks to a landing site featuring non-industry sponsored CME. We modelled the effects of social media platform, CME topic, and hook using negative binomial regression on clicks to a single landing site. We used clicks to landing site adjusted for exposure and message number to calculate rate ratios. To understand how physicians interact with CME content on social media, we also conducted interviews with 10 physicians. The National Physicians Alliance (NPA) membership. NPA e-mail recipients, Facebook followers and friends, and Twitter followers. Clicks to the NPA's CME landing site. On average, 4,544 recipients received each message. Messages generated a total of 592 clicks to the landing site, for a rate of 5.4 clicks per 1000 recipients exposed. There were 5.4 clicks from e-mail, 11.9 clicks from Facebook, 5.5 clicks from paid Facebook, and 6.9 clicks from Twitter to the landing site for 1000 physicians exposed to each of 4 selected CME modules. A Facebook post generated 2.3x as many clicks to the landing site as did an e-mail after controlling for participant exposure, hook type and CME topic (pmedia might not be a preferred vehicle for disseminating CME. Social media has a modest impact on driving traffic to evidence-based CME options. Facebook had a superior effect on driving physician web traffic to evidence-based CME compared to other social media platforms and email.

  10. LHCSR Expression under HSP70/RBCS2 Promoter as a Strategy to Increase Productivity in Microalgae

    Full Text Available Microalgae are unicellular photosynthetic organisms considered as potential alternative sources for biomass, biofuels or high value products. However, limited biomass productivity is commonly experienced in their cultivating system despite their high potential. One of the reasons for this limitation is the high thermal dissipation of the light absorbed by the outer layers of the cultures exposed to high light caused by the activation of a photoprotective mechanism called non-photochemical quenching (NPQ. In the model organism for green algae Chlamydomonas reinhardtii, NPQ is triggered by pigment binding proteins called light-harvesting-complexes-stress-related (LHCSRs, which are over-accumulated in high light. It was recently reported that biomass productivity can be increased both in microalgae and higher plants by properly tuning NPQ induction. In this work increased light use efficiency is reported by introducing in C. reinhardtii a LHCSR3 gene under the control of Heat Shock Protein 70/RUBISCO small chain 2 promoter in a npq4 lhcsr1 background, a mutant strain knockout for all LHCSR genes. This complementation strategy leads to a low expression of LHCSR3, causing a strong reduction of NPQ induction but is still capable of protecting from photodamage at high irradiance, resulting in an improved photosynthetic efficiency and higher biomass accumulation.

    For a number of reasons, meat products are an exceptionally adequate means for introducing different bioactive compounds into the diet without modifying eating habits. In recent years, there has been a notable development of meat products designed as potentially functional foods. Within the framework of the functional food, this article provides a general view of the reasons that motivate and justify their formulation, with special emphasis on: a) aspects to be considered in their design in order to be able to make nutrition claims and statements concerning their health-promoting properties; b) the strategies employed to optimize the presence of functional ingredients, favoring the presence of beneficial bioactive compounds and limiting others with negative consequences for our health, and c) the procedures for demonstrating a relationship between the consumption of potentially functional meat products with beneficial effects on health and the way in which these studies are reflected in the literature.

    To explore pharmacist/pharmacy staff trainers' perspectives on conducting community-based training to promote responsible self-medication, and to evaluate knowledge gained among community representatives participating in the training. Training was conducted in four districts/cities in East Java, Indonesia in 2016. A pre-test/post-test study was used to evaluate the knowledge of 129 community representatives (participants) before/after the training; pre-test and post-test scores as well as absolute gain were determined. Four focus group discussions with 20 pharmacist/pharmacy staff (trainers) were conducted after the training, and the data were thematically analysed. Overall mean test scores for community representatives significantly improved from 14.11 to 15.70 after the training (P < 0.001). The average total absolute gain was 1.85 (95% CI 1.29 to 2.39). To reach local communities, trainers suggested improvements to the content and structure of the module, training aids, trainer competency, approach and time allocation. Community-based training provides a potential strategy to improve community knowledge of medications. Findings from this study should inform strategies for a broader uptake amongst local communities in Indonesia. © 2018 Royal Pharmaceutical Society.

  14. Safety and clinical efficacy of some radiation-sterilized medical products and pharmaceuticals

    Medical products and pharmaceuticals must conform to certain minimum physico-chemical microbiological and biological requirements. The biological requirements comprise principally testing for toxicity, safety, and pyrogens. Besides the above-mentioned criteria, there are two other important characteristics, viz. clinical efficacy and tolerance in animal and/or human beings. These latter requirements, expected from the final product released for general human use, are not carried out routinely. In the present-day pharmaceutical and medical technology, numerous mew products are appearing, many of them requiring radiation sterilization as they are not stable towards the other conventional methods of sterilization. While the post-irradiation physicochemical changes in a product may not be significant, the bio-availability or biological activity of the product may be affected to a more significant extent. Some evidence of this has recently been reported. Hence, it is desirable to carry out studies on safety as well as clinical efficacy on irradiated products. This paper describes some studies on plastic-based medical products, a pharmaceutical raw material, a typical infusion fluid such as normal saline, antibiotics and their ointments. (author)

    The effectiveness of many vaccines licensed for clinical use relates to the induction of neutralising antibodies, facilitated by the inclusion of vaccine adjuvants, particularly alum. However, the ability of alum to preferentially promote humoral rather than cellular, particularly Th1-type responses, is not well understood. We demonstrate that alum activates immunosuppressive mechanisms following vaccination, which limit its capacity to induce Th1 responses. One of the key cytokines limiting excessive immune responses is IL-10. Injection of alum primed draining lymph node cells for enhanced IL-10 secretion ex vivo. Moreover, at the site of injection, macrophages and dendritic cells were key sources of IL-10 expression. Alum strongly enhanced the transcription and secretion of IL-10 by macrophages and dendritic cells. The absence of IL-10 signalling did not compromise alum-induced cell infiltration into the site of injection, but resulted in enhanced antigen-specific Th1 responses after vaccination. In contrast to its decisive regulatory role in regulating Th1 responses, there was no significant change in antigen-specific IgG1 antibody production following vaccination with alum in IL-10-deficient mice. Overall, these findings indicate that injection of alum promotes IL-10, which can block Th1 responses and may explain the poor efficacy of alum as an adjuvant for inducing protective Th1 immunity. © 2018 WILEY-VCH Verlag GmbH & Co.

    Full Text Available Epidemiological studies propose a protective role for dietary fiber in colon cancer (CRC. One possible mechanism of fiber is its fermentation property in the gut and ability to change microbiota composition and function. Here, we investigate the role of a dietary fiber mixture in polyposis and elucidate potential mechanisms using TS4Cre × cAPCl°x468 mice. Stool microbiota profiling was performed, while functional prediction was done using PICRUSt. Stool short-chain fatty acid (SCFA metabolites were measured. Histone acetylation and expression of SCFA butyrate receptor were assessed. We found that SCFA-producing bacteria were lower in the polyposis mice, suggesting a decline in the fermentation product of dietary fibers with polyposis. Next, a high fiber diet was given to polyposis mice, which significantly increased SCFA-producing bacteria as well as SCFA levels. This was associated with an increase in SCFA butyrate receptor and a significant decrease in polyposis. In conclusion, we found polyposis to be associated with dysbiotic microbiota characterized by a decline in SCFA-producing bacteria, which was targetable by high fiber treatment, leading to an increase in SCFA levels and amelioration of polyposis. The prebiotic activity of fiber, promoting beneficial bacteria, could be the key mechanism for the protective effects of fiber on colon carcinogenesis. SCFA-promoting fermentable fibers are a promising dietary intervention to prevent CRC.

    The biosurfactant-producing Pseudomonas aeruginosa A11, with plant-growth-promoting (PGP) and multi-metal-resistant (MMR) features was isolated from the rhizosphere of a wild plant Parthenium hysterophorus. The strain A11 was able to utilize glycerol as a carbon source and produce 4,436.9 mg/L of biosurfactant after 120 h of incubation. The biosurfactants was characterized as rhamnolipids (RLs) by thin layer chromatography, Fourier transform infrared spectroscopy, nuclear magnetic resonance, and liquid chromatography-mass spectrometry analysis. Eight different RLs congeners were detected with RhaRhaC₁₀C₁₀ being most abundant. The purified rhamnolipid, dirhamnolipid, and monorhamnolipid reduced the surface tension of water to 29, 36, and 42 mN/m with critical micelle concentration of 83, 125, and 150 mg/L, respectively. The strain A11 demonstrated resistance against all the metals detected in rhizosphere except Hg and Ni. The strain A11 also possessed plant-growth-promoting features like siderophores, hydrogen cyanide, catalase, ammonia production, and phosphate solubilization. The dirhamnolipids formed crystals upon incubation at 4 °C, thus making separation of dirhamnolipids easy. Biosurfactant-producing ability along with MMR and PGP traits of the strain A11 makes it a potential candidate for application in the bacterial assisted enhancement of phytoremediation of heavy-metal-contaminated sites.

    An alternative is presented by promoting a reaction with infrared irradiation to obtain different 4-aryl-3-cyano-5-ethoxycarbonyl-6-methyl-2-pyridone derivatives 9 a-k. The process was carried out with a green approach from the corresponding 4 H-pyrans, using mild reaction conditions and infrared irradiation as the energy source. In the first stage, the reaction produced 1,2,3,4-tetrahydropyridine-2-one derivatives 8 a-k, followed by an oxidative step to afford the target molecules in good yields. The structure of products 9 a-k was confirmed by Ft-IR, {sup 1}H NMR and {sup 13}C NMR spectroscopic techniques and X-ray diffraction. It was found that the efficiency of the reaction depends on the catalyst and the solvent, as well as on the aldehyde substituents. (Author)

    1995-01-01

    The current transition to a market economy in Central and Eastern Europe and in the Newly Independent States of the Former Soviet Union provides an unique opportunity to integrate environmental considerations into the process of economic restructuring. The use of environmental audits in industry to identify savings in energy, water, and other raw materials is a particularly cost-effective approach for promoting more efficient industrial production and improvements in environmental performance. This volume brings together the papers given at a seminar on ''Auditing to Improve Safety, Environmental Performance and Economic Efficiency'', where the chemical Industry in the Ukraine was a particular focus of discussion. The practical experiences described in these papers demonstrate how environmental and economic performance can be enhanced at little or no cost. Later on, only the article concerning the chemical industry of Ukraine has been analysed. (authors). 7 figs., 2 tabs

    The Global Environment Facility (GEF) has allocated more than $90 million over the past 10 years to eight projects promoting energy-efficient products in developing and transition countries. We review the early experience from these projects and suggest lessons relevant to market transformation programs. Based on GEF project designs, we also propose a menu of generic supply-side and demand-side interventions useful for designing and analyzing market transformation programs. Experience suggests that institutional and policy changes, leading to sustained price reductions and higher market volumes, are important outcomes for market transformation; that market impacts can appear early in programs due to increased expectations and awareness; and that projects can have a catalytic effect. We recommend eight principles for designers of future projects but caution that no single approach guarantees success

    Adiponectin is a major adipocytokine secreted from mammalian adipocytes. Relatively low expression of adiponectin is associated with various human metabolic diseases and some cancers. Adiponectin-secreting compounds have therapeutic potential for these diseases. Adipogenesis of human bone marrow-mesenchymal stem cells (hBM-MSCs) has been used as a phenotypic assay to find adiponectin secreting compounds. In a phytochemical library screen, 2-formyl-komarovicine, 1-(quinolin-8-yl)-1,3,4,9-tetrahydro-2H-pyrido[3,4-b]indole-2-carbaldehyde, isolated from Nitraria komarovii was identified as a potential adiponectin-secreting compound. To validate the results of the impure phytochemical, we synthesized 2-formyl-komarovicine. The synthetic 2-formyl-komarovicine significantly promoted adiponectin production during adipogenesis in hBM-MSCs. In a target identification experiment, 2-formyl-komarovicine bound to peroxisome proliferator-activated receptor γ (PPARγ) in a concentration-dependent manner. Notably, 2-formyl-komarovicine competitively inhibited the adiponectin-promoting activity of a full PPARγ agonist, troglitazone, in hBM-MSCs, which is a pharmacological feature of a partial agonist. The ligand-docking model showed that 2-formyl-komarovicine interacted with the hydrophobic pocket of the PPARγ ligand-binding domain, but lacked an interaction to stabilize helix H12, which is one of the major binding themes of PPARγ partial agonists. We concluded that 2-formyl-komarovicine provides a novel pharmacophore for PPARγ partial agonists to increase adiponectin production. Copyright © 2018 Elsevier Ltd. All rights reserved.

    The purpose of this study was to describe the nature of marketing strategies for multivitamin and multimineral (MVM) supplement packaging and to assess the extent to which these supplements are marketed as food products. A cross-sectional study of children's supplement packaging was conducted. Descriptive statistics identified common marketing practices. Websites of the three largest retail chain pharmacies in the United States and MVM manufacturers were accessed. The study's sample consisted of packaging for 52 children's MVM supplements. Child-targeted marketing included reference to trademarked characters on 42.3% of MVM packaging (n = 22). More than 80% of the sample (n = 42) listed fruity flavors and almost all packaging included descriptive words related to the MVMs' shape and/or flavor (88.5%, n = 46). Nearly one-fifth of the packaging (n = 10) pictured a food item. With respect to parent-targeted promotional language, almost 83% of the supplement packages (n = 43) included text on the support of bodily structure/function. More than half of the sample (53.8%, n = 28) had promotional language related to dietary practice (e.g. organic, gluten-free). Pediatricians can play a role in ensuring that parents are aware of (1) possible risks associated with MVM overconsumption, and (2) the importance of deriving vitamins and minerals from a balanced diet. Given the high number of exposures to pediatric MVMs among youth and established influence of food marketing on shaping children's perceptions and behaviors, further research is necessary to determine the extent to which children's MVMs are marketed as a food product and perceived as such by children.

    Brassinosteroids (BRs) are essential hormones that play crucial roles in plant growth, reproduction and response to abiotic and biotic stress. In Arabidopsis, AtCYP85A2 works as a bifunctional cytochrome P450 monooxygenase to catalyse the conversion of castasterone to brassinolide, a final rate-limiting step in the BR-biosynthetic pathway. Here, we report the functional characterizations of PtCYP85A3, one of the three AtCYP85A2 homologous genes from Populus trichocarpa. PtCYP85A3 shares the highest similarity with AtCYP85A2 and can rescue the retarded-growth phenotype of the Arabidopsis cyp85a2-2 and tomato d x mutants. Constitutive expression of PtCYP85A3, driven by the cauliflower mosaic virus 35S promoter, increased the endogenous BR levels and significantly promoted the growth and biomass production in both transgenic tomato and poplar. Compared to the wild type, plant height, shoot fresh weight and fruit yield increased 50%, 56% and 43%, respectively, in transgenic tomato plants. Similarly, plant height and stem diameter increased 15% and 25%, respectively, in transgenic poplar plants. Further study revealed that overexpression of PtCYP85A3 enhanced xylem formation without affecting the composition of cellulose and lignin, as well as the cell wall thickness in transgenic poplar. Our finding suggests that PtCYP85A3 could be used as a potential candidate gene for engineering fast-growing trees with improved wood production. © 2017 The Authors.

    The bacterial contamination was assessed on randomly taken samples of blood-transfusion devices, donor sets, intra-uterine contraceptive devices and inserters, surgical gloves and dressing material prior to sterilization. The quantitative and qualitative efficiency of six nutrient media was compared. The best results were obtained with the enriched ''Universal'' medium. It was confirmed that the contamination of plastic products was low compared with dressing material. Most frequently, Gram-positive aerobic spore-forming rods and Gram-positive cocci were found on non-sterile medical disposable products. A method was tested to obtain a general informative picture of the resistance of bacteria on products. The methods used for choosing the dose for radiation sterilization of medical products are discussed. (author)

    This study aimed to compare scientific production by providing quantitative evaluation of science output in five Western Iranian Medical Universities including Hamedan, Ilam, Kermanshah, Kurdistan and Lorestan University of Medical Sciences using scientometrics indicators based on data indexed in Scopus for period between the years 2010 to 2014. In this scientometric study data were collected using Scopus database. Both searching and analyzing features of Scopus were used to data retrieval and analysis. We used Scientometrics indicators including number of publications, number of citations, nationalization index (NI), Internationalization Index (INI), H-index, average number of citations per paper, and growth index. Five Western Iranian Universities produced over 3011 articles from 2010 to 2014. These articles were cited 7158 times with an average rate of 4.2 citations per article. H- Index of under study universities are varying from 14 to 30. Ilam University of Medical Sciences had the highest international collaboration with an INI of 0.33 compared to Hamedan and Kermanshah universities with INI of 0.20 and 0.16 respectively. The lowest international collaboration belonged to Lorestan University of Medical Sciences (0.07). The highest Growth Index belonged to Kurdistan University of Medical Sciences (69.7). Although scientific production of five Western Iranian Medical Universities was increasing, but this trend was not stable. To achieve better performance it is recommended that five Western Iranian Universities stabilize their budgeting and investment policies in research.

    Since 2012, the Chablais region (only in France) has acquired the Geopark label. This Geopark contributes to sustainable economic development of the region through geotourism. Moreover, the three Chablais (figure 1) are concerned by an Interreg IV program since 2009 (program of cooperation between European countries). The main objective of this program is to enhance the heritage resources (nature, culture and lifestyle of the region) (www.interreg-francesuisse.org). Therefore, the geotourism offer in this area just waiting to expand. The geodidactics models like the simplification of the scientific content are essential for geoheritage promotion, because this content must be available to a wide audience, allowing thereby the geoheritage recognition. The geotourism permits to apply different models (Cayla et al. 2010, Sellier, 2009) through a wide range of geotourism products, like guide, educational panels, thematic hikes and recently developed, new medias (website, smartphone applications). A geotourism product is based on four areas of questioning and was developed by Martin et al. (2010): (1) site (choice of sites to be valued), (2) public (a family public, good example of heterogeneous public), (3) contents (reasoning on geodidactics models) and (4) support (smartphone application). These four areas are very fundamental before the creation of any geotourism product. These reflexions aim to obtain a mediation product that integrates into geotourism offer of a region and contributes to its development and meets public expectations. New media, such as digital media - smartphone, tablets, website - become geotourism products more and more attractive. In addition, the necessary technologies to develop new media help to integrate a high interactivity potential with the public and thus get their attention. The architecture of this geotourism product is based on the new application developed by the Institute of Geography and sustainability, and the Bureau Relief. One

    Full Text Available There is a wealth of medical information now available to the public through various sources that are not necessarily controlled by medical or healthcare professionals. In Australia there has been a strong movement in the health consumer arena of consumer-led sharing and production of medical information and in healthcare decision-making. This has led to empowerment of the public as well as increased knowledge-sharing. There are some successful initiatives and strategies on consumer- and public-led sharing of medical information, including the formation of specialised consumer groups, independent medical information organisations, consumer peer tutoring, and email lists and consumer networking events. With well-organised public initiatives and networks, there tends to be fairly balanced information being shared. However, there needs to be caution about the use of publicly available scientific information to further the agenda of special-interest groups and lobbying groups to advance often biased and unproven opinions or for scaremongering. With the adoption of more accountability of medical research, and the increased public scrutiny of private and public research, the validity and quality of medical information reaching the public is achieving higher standards.

    The inpatient medication delivery system used at a large regional acute care hospital in the Midwest had become antiquated and inefficient. The existing 24-hr medication cart-fill exchange process with delivery to the patients' bedside did not always provide ordered medications to the nursing units when they were needed. In 2007 the principles of the Toyota Production System (TPS) were applied to the system. Project objectives were to improve medication safety and reduce the time needed for nurses to retrieve patient medications. A multidisciplinary team was formed that included representatives from nursing, pharmacy, informatics, quality, and various operational support departments. Team members were educated and trained in the tools and techniques of TPS, and then designed and implemented a new pull system benchmarking the TPS Ideal State model. The newly installed process, providing just-in-time medication availability, has measurably improved delivery processes as well as patient safety and satisfaction. Other positive outcomes have included improved nursing satisfaction, reduced nursing wait time for delivered medications, and improved efficiency in the pharmacy. After a successful pilot on two nursing units, the system is being extended to the rest of the hospital. © 2010 National Association for Healthcare Quality.

  18. Medical Isotopes Production Project: Molybdenum-99 and related isotopes: Environmental Impact Statement, Volume I

    International Nuclear Information System (INIS)

    1996-04-01

    This Environmental Impact Statement (EIS) provides environmental and technical information concerning the U.S. Department of Energy's (DOE) proposal to establish a domestic source to produce molybdenum-99 (Mo-99) and related medical isotopes (iodine-131, xenon-133 and iodine-125). Mo-99, a radioactive isotope of the element molybdenum, decays to form metastable technetium-99 (Tc-99m), a radioactive isotope used thousands of times daily in medical diagnostic procedures in the U.S. Currently, all Mo-99 used in the U.S. is obtained from a single Canadian source. DOE is pursuing the Medical Isotopes Production Project in order to ensure that a reliable supply of Mo-99 is available to the U.S. medical community. Under DOE's preferred alternative, the Chemistry and Metallurgy Research Facility at the Los Alamos National Laboratory (LANL) and the Annular Core Research Reactor and Hot Cell Facility at Sandia National Laboratories/New Mexico (SNL/NM) would be used for production of the medical isotopes. In addition to the preferred alternative, three other reasonable alternatives and a no action alternative are analyzed in detail. The sites for the three reasonable alternatives are LANL, Oak Ridge National Laboratory (ORNL), and Idaho National Engineering Laboratory (INEL). The analyses in this EIS indicate no significant difference in the potential environmental impacts among the alternatives. Each of the alternatives would use essentially the same technology for the production of the medical isotopes. Minor differences in environmental impacts among alternatives relate to the extent of activity necessary to modify and restart (as necessary) existing reactors and hot cell facilities at each of the sites, the quantities, of low-level radioactive waste generated, how such waste would be managed, and the length of time needed for initial and full production capacity

    Full Text Available Metabolic networks revolve around few metabolites recognized by diverse enzymes and involved in myriad reactions. Though hub metabolites are considered as stepping stones to facilitate the evolutionary expansion of biochemical pathways, changes in their production or consumption often impair cellular physiology through their system-wide connections. How does metabolism endure perturbations brought immediately by pathway modification and restore hub homeostasis in the long run? To address this question we studied laboratory evolution of pathway-engineered Escherichia coli that underproduces the redox cofactor NADPH on glucose. Literature suggests multiple possibilities to restore NADPH homeostasis. Surprisingly, genetic dissection of isolates from our twelve evolved populations revealed merely two solutions: (1 modulating the expression of membrane-bound transhydrogenase (mTH in every population; (2 simultaneously consuming glucose with acetate, an unfavored byproduct normally excreted during glucose catabolism, in two subpopulations. Notably, mTH displays broad phylogenetic distribution and has also played a predominant role in laboratory evolution of Methylobacterium extorquens deficient in NADPH production. Convergent evolution of two phylogenetically and metabolically distinct species suggests mTH as a conserved buffering mechanism that promotes the robustness and evolvability of metabolism. Moreover, adaptive diversification via evolving dual substrate consumption highlights the flexibility of physiological systems to exploit ecological opportunities.

    OBJECTIVES: Aerobic exercise training prevents cardiovascular risks. Regular exercise promotes functional and structural adaptations that are associated with several cardiovascular benefits. The aim of this study is to investigate the effects of swimming training on coronary blood flow, adenosine production and cardiac capillaries in normotensive rats. METHODS: Wistar rats were randomly divided into two groups: control (C) and trained (T). An exercise protocol was performed for 10 weeks and 60 min/day with a tail overload of 5% bodyweight. Coronary blood flow was quantified with a color microsphere technique, and cardiac capillaries were quantified using light microscopy. Adenine nucleotide hydrolysis was evaluated by enzymatic activity, and protein expression was evaluated by western blot. The results are presented as the means ± SEMs (p<0.05). RESULTS: Exercise training increased the coronary blood flow and the myocardial capillary-to-fiber ratio. Moreover, the circulating and cardiac extracellular adenine nucleotide hydrolysis was higher in the trained rats than in the sedentary rats due to the increased activity and protein expression of enzymes, such as E-NTPDase and 5′-nucleotidase. CONCLUSIONS: Swimming training increases coronary blood flow, number of cardiac capillaries, and adenine nucleotide hydrolysis. Increased adenosine production may be an important contributor to the enhanced coronary blood flow and angiogenesis that were observed in the exercise-trained rats; collectively, these results suggest improved myocardial perfusion.

    This project describes an investigation towards the production of 99mTc with a small medical cyclotron. This endeavor addresses the current urgent problem of availability of 99mTc due to the ongoing production reactor failures and the upcoming Canadian reactor shut down. Currently, 99mTc is produced via nuclear fission using highly enriched uranium which is a concern due to nuclear proliferation risks. In addition to this, the United States is dependent solely on currently unreliable foreign sources of this important medical isotope. Clearly, a need exists to probe alternative production routes of 99mTc. In the first year, this project measured cross-sections and production yields of potential pathways to 99mTc and associated radionuclidic impurities produced via these pathways using a small 15 MeV medical cyclotron. During the second and third years target systems for the production of 99mTc via the most promising reaction routes were developed and separation techniques for the isolation of 99mTc from the irradiated target material will be investigated. Systems for the recycling of the enriched target isotopes as well as automated target processing systems were examined in years four and five. This project has the potential to alleviate some of the current crisis in the medical community by developing a technique to produce 99mTc on location at a university hospital. This technology will be applicable at many other sites in the United States as many other similar, low energy (<20 MeV) cyclotrons (currently used for a few hours per day for the production of [18F]fluorodeoxyglucose) are available for production of 99mTc though this method, thus leading to job creation and preservation.

  6. Formation and elution of toxic compounds from sterilized medical products: toxic compound formation from irradiated products

    No formation of MDA was observed in chain-extended thermoplastic polyurethane (PU) when sterilized by autoclave or γ-ray irradiation. No formation of MDA was observed in nonchain-extended thermoplastic PU when sterilized by γ-ray irradiation. Less than 1 ppm MDA was produced in nonchain-extended thermoplastic PU sterilized by autoclave sterilization. Autoclave sterilization did not produce MDA in thermosetting PU potting material. MDA formation in potting material was promoted by γ-irradiation and increased with increasing irradiation at a quadratic equation of regression. MDA formation at 100 kGy irradiation is a few ppm and < 1 ppm at 25kGy irradiation, therefore the potential risk to human recipients was not significant. The elution of compounds other than MDA from potting material was more problematic. Solvent extracts from potting material presented mutagenicity in the absence of metabolic activity. MDA presented mutagenicity in the presence of metabolic activity, therefore MDA was not the mutagenic trigger. The chemical and biological characteristics of the specific mutagens required to identify in a further study. Negative promotion of MDA formation and a less presence of mutagen in autoclave sterilized potting material indicated that autoclave sterilization was preferable. (Author)

    Medical students have consistently expressed interest in learning about alternative healing modalities, especially herbal and natural products. To fill this void in medical education at our institution, a novel elective was developed and implemented for fourth year medical students. This herbal/natural product course uses guest lecturers, classroom presentations, and active learning mechanisms that include experiential rotations, case-based learning, and team-based learning to increase student knowledge of herbal/natural product safety and efficacy. Knowledge outcomes were evaluated via administration of a pre- and post-course test (paired student t-test). End-of-course evaluations (Likert-type questions and narrative responses) were used to assess student opinion of knowledge and skills imparted by the elective and overall course content (mean, standard deviation). Over three academic years, 23 students have enrolled in this elective. More than 60% of participants have been female and nearly half of the students (43%) have pursued residencies in primary care. Completion of the course significantly increased student knowledge of common herbal/natural product mechanisms, uses, adverse effects, and drug-interactions as determined by a pre- and post-course knowledge assessment (45%±10% versus 78%±6%; pvariety of activities to which they were exposed and the open classroom discussions that resulted. While students tended to view some alternative medical systems with skepticism, they still believed it was valuable to learn what these modalities encompass. Development and implementation of a herbal/natural product elective that engages undergraduate medical students through active learning mechanisms and critical analysis of the literature has proven effective in increasing knowledge outcomes and is deemed to be a valuable curricular addition by student participants. In the future, it will be of interest to explore mechanisms for expanding the course to reach a larger

    The current European system for medical devices is governed by three EC directives: the Medical Device Directive 93/42/EEC, the In-Vitro Diagnostic Directive 98/79/EC and the Active Implantable Medical Device Directive 90/385/EEC and regulates marketing and post-market surveillance of medical devices in the European Economic Area. In cases of incidents and field safety corrective actions (FSCA) manufacturers have to inform the responsible Competent Authority, which is the Federal Institute for Drugs and Medical Devices (BfArM) and the public by field safety notices (FSN). In this study we analyzed FSN of medical devices exclusively serving for diagnostics or treatment in pulmonology (e.g. nebulizers, oxygen concentrators, pulse oximeters, lung function analyzers, and non-active devices for treatment). FSCA and FSN publicized by BfArM in 2005-2013 were analyzed in respect to the MEDDEV 2.12-1 rev 8. In total 41 FSCA were publicized for the included products. German and English FSN were found in 36/35 cases, respectively. FSN were clearly characterized as FSN in 22/20 cases and declaration of the type of action was found in 27/26 cases, respectively. Product names were provided in all cases. Lot numbers or other information for product characterization were available in 7/8 and 26/24 cases, respectively. Detailed information regarding FSCA and product malfunction were found in 27/33 and 36/35 cases, respectively. Information on product related risks with previous use of the affected product was provided in 24/23 cases. In 34/34 cases manufacturers provided information to mitigate product related risks. Requests to pass FSN to persons needing awareness were found in 10/14 cases. Contact data were provided in 30/30 cases. Confirmation that the Competent Authority was informed was found in 12/14 cases and in 19/18 cases a customer confirmation was included. The obtained data suggest that there is an increasing annual number of FSCA and most FSN fulfill the criteria of

    To summarize, from preliminary observations on the possible effects of radioactive fall-out, it may be inferred that in addition to the secondary products of ionizing irradiation per se, the stable end-products of the transmutation of certain radionuclides may adversely influence cellular metabolism, including mutagenesis. The discussion of the possible role of intracellular barium as an end-product of 137Cs decay is offered as an example of an unpredictable number of broad ecological, as well as the more limited medical, effects that may be of both clinical and climatological significance

    Based on experiences with the Productive Cooperative Movement and the Parasite Control Movement in Japan, the Japanese Family Planning Movement began in April 1954. The resultant private and nonprofit Japan Family Planning Association (JFPA) followed and it served to help Japan achieve its goal of reducing fertility by promoting family planning. It did so by publishing a monthly newsletter on family planning, hosting meetings and national conventions, spreading information via the mass media, and selling contraceptives and educational materials. JFPA earned funding from these sales with no support from the government thereby establishing self dependence and freedom to speak candidly to the government. The JFPA learned that families wanted to improve their standard of living and were willing to limit family size to 2 children. After the birth rate peaked in 1955, the birth rate and the number of illegal abortions decreased. In the 1950s, JFPA joined the International Planned Parenthood Federation and subsequently learned of the problems faced by developing countries. Based on the successful reduction of fertility in Japan and a strong economic base, JFPA and the government were in a position to organize an international cooperation program for family planning. Therefore, the leader of JFPA resigned to found the Japanese Organization for International Cooperation in Family Planning which promotes family planning in developing countries via its integrated family planning, nutrition, and parasite control program. A steering committee composed of leaders from government, universities, and private organizations sets the policies for the program in each country. It is to the Japanese government's advantage to work with private organizations instead of providing all social services because they are flexible and provide administrative stability and national expenses are minimized.

    Full Text Available Salvia miltiorrhiza is known for tanshinones and salvianolic acids, which have been shown to have a protective effect against ROS, especially for cardiovascular diseases and other various ailments of human organs. Due to the low yield of tanshinones and their analogs in S. miltiorrhiza, multiple stimulation strategies have been developed to improve tanshinones production in plant tissue cultures. Endophytic fungi have been reported to form different relationships with their host plants, including symbiotic, mutualistic, commensalistic, and parasitic interactions. Thus we take the assumption that endophytic fungi may be a potential microbial tool for secondary metabolism promotion in medicinal plants. We recently isolated Chaetomium globosum D38 from the roots of S. miltiorrhiza and our study aimed to examine the effects of this live endophytic fungus D38 and its elicitor on the accumulation of tanshinones in the hairy root cultures of S. miltiorrhiza. Our results revealed that C. globosum D38 mainly colonized in the intercellular gap of xylem parenchyma cells of S. miltiorrhiza hairy roots during the long term co-existence without any toxicity. Moreover, both of the live fungus and its mycelia extract could increase the production of tanshinones, especially for dihydrotanshinone I and cryptotanshinone. The effect of the mycelia extract was much stronger than that of the live fungus on tanshinones synthesis, which significantly increased the transcriptional activity of those key genes in tanshinone biosynthetic pathway. Furthermore, the live C. globosum D38 could also be made into biotic fertilizer used for S. miltiorrhiza seedlings culture, which not only significantly promoted the growth of the host plant, but also notably enhanced the accumulation of tanshinones and salvianolic acids. We thus speculated that, in the soil environment D38 could form bitrophic and mutual beneficial interactions with the host and enhance the plant growth and its

    This review introduces the concept of culture-sensitive health communication. The basic premise is that congruency between the recipient's cultural characteristics and the respective message will increase the communication's effectiveness. Culture-sensitive health communication is therefore defined as the deliberate and evidence-informed adaptation of health communication to the recipients' cultural background in order to increase knowledge and improve preparation for medical decision making and to enhance the persuasiveness of messages in health promotion. To achieve effective health communication in varying cultural contexts, an empirically and theoretically based understanding of culture will be indispensable. We therefore define culture, discuss which evolutionary and structural factors contribute to the development of cultural diversity, and examine how differences are conceptualized as scientific constructs in current models of cultural differences. In addition, we will explicate the implications of cultural differences for psychological theorizing, because common constructs of health behavior theories and decision making, such as attitudes or risk perception, are subject to cultural variation. In terms of communication, we will review both communication strategies and channels that are used to disseminate health messages, and we will discuss the implications of cultural differences for their effectiveness. Finally, we propose an agenda both for science and for practice to advance and apply the evidence base for culture-sensitive health communication. This calls for more interdisciplinary research between science and practice but also between scientific disciplines and between basic and applied research. © The Author(s) 2015.

    Full Text Available Liver regeneration is clinically of major importance in the setting of liver injury, resection or transplantation. We have demonstrated that the NF-κB inhibitory protein A20 significantly improves recovery of liver function and mass following extended liver resection (LR in mice. In this study, we explored the Systems Biology modulated by A20 following extended LR in mice.We performed transcriptional profiling using Affymetrix-Mouse 430.2 arrays on liver mRNA retrieved from recombinant adenovirus A20 (rAd.A20 and rAd.βgalactosidase treated livers, before and 24 hours after 78% LR. A20 overexpression impacted 1595 genes that were enriched for biological processes related to inflammatory and immune responses, cellular proliferation, energy production, oxidoreductase activity, and lipid and fatty acid metabolism. These pathways were modulated by A20 in a manner that favored decreased inflammation, heightened proliferation, and optimized metabolic control and energy production. Promoter analysis identified several transcriptional factors that implemented the effects of A20, including NF-κB, CEBPA, OCT-1, OCT-4 and EGR1. Interactive scale-free network analysis captured the key genes that delivered the specific functions of A20. Most of these genes were affected at basal level and after resection. We validated a number of A20's target genes by real-time PCR, including p21, the mitochondrial solute carriers SLC25a10 and SLC25a13, and the fatty acid metabolism regulator, peroxisome proliferator activated receptor alpha. This resulted in greater energy production in A20-expressing livers following LR, as demonstrated by increased enzymatic activity of cytochrome c oxidase, or mitochondrial complex IV.This Systems Biology-based analysis unravels novel mechanisms supporting the pro-regenerative function of A20 in the liver, by optimizing energy production through improved lipid/fatty acid metabolism, and down-regulated inflammation.

    Historically, the production of molybdenum-99 in the NRU research reactors at Chalk River, Canada has been extracted from reactor targets employing highly enriched uranium (HEU). The molybdenum extraction process from the HEU targets provided predictable, consistent yields for our high-volume molybdenum production process. A reliable supply of HEU for the NRU research reactor targets has enabled MDS Nordion to develop a secure chain of medical isotope supply for the international nuclear medicine community. Each link of the isotope supply chain, from isotope production to patient application, has been established on a proven method of HEU target irradiation and processing. To ensure a continued reliable and timely supply of medical isotopes, the design of the MAPLE facilities was based on our established process - extraction of isotopes from HEU target material. However, in concert with the global trend to utilize low enriched uranium (LEU) in research reactors, MDS Nordion has launched a program to convert the MAPLE facilities to LEU targets. An initial feasibility study was initiated to identify the technical issues to convert the MAPLE targets from HEU to LEU. This paper will present the results of the feasibility study. It will also describe future challenges and opportunities in converting the MAPLE facilities to LEU targets for large scale, commercial medical isotope production. (author)

    The filamentous ascomycete Aspergillus niger is used in many industrial processes for the production of enzymes and organic acids by batch and fed-batch cultivation. An alternative technique is continuous cultivation, which promises improved yield and optimized pipeline efficiency. In this work, we have used perfusion (retentostat) cultivation to validate two promoters that are suitable for A. niger continuous cultivation of industrially relevant products. Firstly, promoters of genes encoding either an antifungal protein (Panafp) or putative hydrophobin (PhfbD) were confirmed as active throughout retentostat culture by assessing mRNA and protein levels using a luciferase (mluc) reporter system. This demonstrated the anafp promoter mediates a high but temporally variable expression profile, whereas the hfbD promoter mediates a semi-constant, moderate-to-high protein expression during retentostat culture. In order to assess whether these promoters were suitable to produce heterologous proteins during retentostat cultivation, the secreted antifungal protein (AFP) from Aspergillus giganteus, which has many potential biotechnological applications, was expressed in A. niger during retentostat cultivation. Additionally, this assay was used to concomitantly validate that native secretion signals encoded in anafp and hfbD genes can be harnessed for secretion of heterologous proteins. Afp mRNA and protein abundance were comparable to luciferase measurements throughout retentostat cultivation, validating the use of Panafp and PhfbD for perfusion cultivation. Finally, a gene encoding the highly commercially relevant thermal hysteresis protein (THP) was expressed in this system, which did not yield detectable protein. Both hfbD and anafp promoters are suitable for production of useful products in A. niger during perfusion cultivation. These findings provide a platform for further optimisations for high production of heterologous proteins with industrial relevance.

    In order to meet US tritium needs to maintain the nuclear weapons deterrent, the Department of Energy (DOE) is pursuing a dual track program to provide a new tritium source. A record of decision is planned for late in 1998 to select either the Accelerator Production of Tritium (APT) or the Commercial Light Water Reactor (CLWR) as the technology for new tritium production in the next century. To support this decision, an APT Project was undertaken to develop an accelerator design capable of producing 3 kg of tritium per year by 2007 (START I requirements). The Los Alamos National Laboratory (LANL) was selected to lead this effort with Burns and Roe Enterprises, Inc. (BREI) / General Atomics (GA) as the prime contractor for design, construction, and commissioning of the facility. If chosen in the downselect, the facility will be built at the Savannah River Site (SRS) and operated by the SRS Maintenance and Operations (M ampersand O) contractor, the Westinghouse Savannah River Company (WSRC), with long-term technology support from LANL. These three organizations (LANL, BREI/GA, and WSRC) are working together under the direction of the APT National Project Office which reports directly to the DOE Office of Accelerator Production which has program authority and responsibility for the APT Project

    The common trend of urban population has been growing significantly in Indonesia for decades, are affected by urban green space conversion. Generally, this area is utilized for urban infrastructures and residences. Furthermore, urban area has grown uncontrollably that could enhance the phenomenon of urban sprawl. The conversion of green urban area and agricultural area will significantly decrease urban food security and quality of urban environment. This problem becomes a serious issue for urban sustainability. Bandung is a city with dense population where there are many poor inhabitants. Families living in poverty are subjected to food insecurity caused by the rise of food prices. Based on the urgency of urban food security and urban environment quality the local government has to achieve comprehensive solutions. This research aims to formulate the policy of productive green open space towards food security for poor people in Bandung. This research not only examines the role played by productive green open space to supply food for the urban poor but also how to govern urban areas sustainably and ensure food security. This research uses descriptive explanatory methodology that describes and explains how to generate policy and strategic planning for edible landscape to promote urban food security. Taman Sari is the location of this research, this area is a populous area that has amount of poor people and has a quite worse quality of urban environment. This study shows that urban green open space has the potential to be utilized as an urban farming land, which poor inhabitants could be main actors to manage urban agriculture to provide their food. Meanwhile, local government could contribute to subsidize the financial of urban farming activities.

    Air pollution has been reported to be associated with increased risks of cognitive impairment and neurodegenerative diseases. Because NO2 is a typical primary air pollutant and an important contributor to secondary aerosols, NO2-induced neuronal functional abnormalities have attracted greater attention, but the available experimental evidence, modulating mechanisms, and targeting medications remain ambiguous. In this study, we exposed C57BL/6J and APP/PS1 mice to dynamic NO2 inhalation and found for the first time that NO2 inhalation caused deterioration of spatial learning and memory, aggravated amyloid β42 (Aβ42) accumulation, and promoted pathological abnormalities and cognitive defects related to Alzheimer’s disease (AD). The microarray and bioinformation data showed that the cyclooxygenase-2 (COX-2)-mediated arachidonic acid (AA) metabolism of prostaglandin E2 (PGE2) played a key role in modulating this aggravation. Furthermore, increasing endocannabinoid 2-arachidonoylglycerol (2-AG) by inhibiting monoacylglycerol lipase (MAGL) prevented PGE2 production, neuroinflammation-associated Aβ42 accumulation, and neurodegeneration, indicating a therapeutic target for relieving cognitive impairment caused by NO2 exposure.

    Full Text Available The search for improvement in the supply management has grown significantly due to the goal of strengthening ties with suppliers to generate mutual benefits. In this context and based on a program of development by Alpha Company, the aim of this study was to identify and analyze the main factors that led the company to design the promotional program, the results of which were obtained from the perception of employees and producers involved in the program as well as their perspectives for the future. Using a qualitative approach, a case study was performed with data collected through semi-structured interviews, in addition to documentary data provided by the company. It was observed that the agricultural development program was created to ensure the supply flow of passion fruit for the company studied, with the provision of technical assistance and minimum price to producers being examples of some of the strings attached. The results obtained so far have been positive both in the perception of the producers and employees, but some aspects can be improved. The program has been shown as an instrument of formalization of a partnership between producer and industry, but there is no expectation, at least for now, of this program expanding into other products.

    Changes in disinfectant type could trigger a cascade of reactions releasing pipe-anchored metals/metalloids into finished water. However, the effect of pre-formed disinfection by-products on the release of sorbed contaminants (arsenic-As in particular) from drinking water distribution system pipe scales remains unexplored. A bench-scale study using a factorial experimental design was performed to evaluate the independent and interaction effects of trihalomethanes (TTHM) and haloacetic acids (HAA) on arsenic (As) release from either scales-only or scale-biofilm conglomerates (SBC) both anchored on asbestos/cement pipe coupons. A model biofilm (Pseudomonas aeruginosa) was allowed to grow on select pipe coupons prior experimentation. Either TTHM or HAA individual dosing did not promote As release from either scales only or SBC, detecting water. In the case of scales-only coupons, the combination of the highest spike level of TTHM and HAA significantly (pwater in pipe networks remains to be investigated in the field.

    Research has shown a fall of research productivity of faculty after their promotion to professor rank. This study explores the factors that lead to this decline in research productivity of professors in medical discipline. A 20-item questionnaire was distributed online to medical professors of a Saudi, Malaysian and a Pakistani medical school. The participants were instructed to select their responses on a 5-point Likert's scale and the collected data was analyzed for quantitative and qualitative results. Of 161, 110 responded; response rate of 68.3%. About 35% professors spent 1-4 hours and 2% spent 19-25 hours per week for research. As many as 7% did not publish a single article and 29% had published 10 or more articles after attaining professor rank. During the last two years, 44% professors had published 5 or more research articles. Majority pointed out a lack of research support and funds, administrative burden and difficulty in data collection as the main obstacles to their research. This research has identified time constraints and insufficient support for research as key barriers to medical professors' research productivity. Financial and technical support and lesser administrative work load are some suggested remedies to foster the professors' research output.

    The consumption of meat products is gradually being increased by the development of livestock raising technology, industrialized farm management and international trade. This increased consumption also created new market for ready-to-eat and ready-to-cook meat products. However, these convenience meat products can be easily contaminated during the processing and storage by pathogens, and there have been many reported cases of food borne illness by meats. One of the most effective methods for the decontamination of meat products is the radiation technology. Food irradiation was the established, well-recognized and safe sterilization method. Many other countries researched the effect of irradiation on the meat products and approved the irradiation. In this article, the effectiveness, the international acceptance, the economics and the research trend of irradiation on meat products have been reviewed. Also, the policy plans for the early approval of the irradiated meat products in Korea and the promotion policy of irradiated meats in market were discussed.

    Recent disruptions in the molybdenum-technetium generator supply chain prompted a review of non-reactor based production methods for both 99 Mo and 99m Tc. Small medical cyclotrons (E p ∼ 16-24 MeV) are capable of producing Curie quantities of 99m Tc from isotopically enriched 100 Mo using the 100 Mo(p,2n) 99m Tc reaction. Unlike most other metallic target materials for routine production of medical radioisotopes, molybdenum cannot be deposited by reductive electroplating from aqueous salt solutions. To overcome this issue, we developed a new process for solid molybdenum targets based on the electrophoretic deposition of fine 100 Mo powder onto a tantalum plate, followed by high temperature sintering. The targets obtained were mechanically robust and thermally stable when irradiated with protons at high power density. (author)

  11. Medical merchants: conflict of interest, office product sales and notifiable conduct.

    2011-01-03

    Professional ethical codes identify the issue of conflict of interest, which can distort doctors' objective judgements concerning the best interests of patients. Legal fiduciary duties may be owed by doctors to patients in situations of potential conflict of interest. Prescribing and dispensing functions have been largely legally separated to prevent conflicts of interest arising. The advent of integrative medicine has been accompanied by an apparent growth of in-house selling of therapeutic products. Medical merchandising constitutes a prima-facie conflict of interest and may amount to notifiable conduct under the Health Practitioner Regulation National Law provisions. We believe that doctors who sell therapeutic products should adhere to strict conditions to avoid significantly departing from accepted professional standards. Doctors who have a reasonable belief that a colleague is failing to comply with these conditions could consider notifying the Medical Board of Australia.

    2015-12-01

    This article aims at analysing how well the Advanced Therapy Medical Product Regulation (EC) No. 1394/2007 (ATMP Regulation) meets the needs of small and medium-sized enterprises (SMES), academia and public tissue establishments developing advanced therapy medical products (ATMPS). Benefits and shortcomings of the ATMP Regulation are identified, and possible amendments are proposed to accelerate the translation of research into advanced therapies and to facilitate the commercialisation of ATMPS whilst ensuring safety. It was set up as a lex specialis to ensure the free movement of ATMPS within the EU in order to facilitate their access to the internal market and to foster the competitiveness of European pharmaceutical companies, while guaranteeing the highest level protection of public health. Since the adoption of the ATMP Regulation in late 2008, only 5 ATMPS have been granted marketing authorisations thus far. Hence, there is a need to analyse whether the ATMP Regulation meets its objectives.

    Kharkov Institute of Physics and Technology (KIPT) of Ukraine in collaboration with Argonne National Laboratory (ANL) has a plan to construct an electron accelerator driven subcritical assembly. One of the facility objectives is the production of medical radioactive isotopes. This paper presents the ANL collaborative work performed for characterizing the facility performance for producing medical radioactive isotopes. First, a preliminary assessment was performed without including the self-shielding effect of the irradiated samples. Then, more detailed investigation was carried out including the self-shielding effect, which defined the sample size and location for producing each medical isotope. In the first part, the reaction rates were calculated as the multiplication of the cross section with the unperturbed neutron flux of the facility. Over fifty isotopes have been considered and all transmutation channels are used including (n, γ), (n, 2n), (n, p), and (γ, n). In the second part, the parent isotopes with high reaction rate were explicitly modeled in the calculations. Four irradiation locations were considered in the analyses to study the medical isotope production rate. The results show the self-shielding effect not only reduces the specific activity but it also changes the irradiation location that maximizes the specific activity. The axial and radial distributions of the parent capture rates have been examined to define the irradiation sample size of each parent isotope

    (1) To describe open source legal data sets, created for research use, that capture the key provisions of US state medical marijuana laws. The data document how state lawmakers have regulated a medicine that remains, under federal law, a Schedule I illegal drug with no legitimate medical use. (2) To demonstrate the variability that exists across states in rules governing patient access, product safety and dispensary practice. Two legal researchers collected and coded state laws governing marijuana patients, product safety and dispensaries in effect on 1 February 2017, creating three empirical legal data sets. We used summary tables to identify the variation in specific statutory provisions specified in each state's medical marijuana law as it existed on 1 February 2017. We compared aspects of these laws to the traditional Federal approach to regulating medicine. Full data sets, codebooks and protocols are available through the Prescription Drug Abuse Policy System (http://www.pdaps.org/; Archived at http://www.webcitation.org/6qv5CZNaZ on 2 June 2017). Twenty-eight states (including the District of Columbia) have authorized medical marijuana. Twenty-seven specify qualifying diseases, which differ across states. All states protect patient privacy; only 14 protect patients against discrimination. Eighteen states have mandatory product safety testing before any sale. While the majority have package/label regulations, states have a wide range of specific requirements. Most regulate dispensaries (25 states), with considerable variation in specific provisions such as permitted product supply sources number of dispensaries per state and restricting proximity to various types of location. The federal ban in the United States on marijuana has resulted in a patchwork of regulatory strategies that are not uniformly consistent with the approach usually taken by the Federal government and whose effectiveness remains unknown. © 2017 Society for the Study of Addiction.

    In contrast to conventional bremsstrahlung photon beam sources, laser backscatter photon sources at electron synchrotrons provide the capability to selectively tune photons to energies of interest. This feature, coupled with the ubiquitous giant dipole resonance excitations of atomic nuclei, promises a fertile method of nuclear isotope production. In this article, we present the results of simulations of production of the medical/industrial isotopes 196Au, 192Ir and 99Mo by (γ,n) reactions. We employ FLUKA Monte Carlo code along with the simulated photon flux for a beamline at the Canadian Light Source in conjunction with a CO2 laser system.

    The authors describe their findings from a study that (1) identified 41 medical schools or medical school departments that used metric systems to quantify faculty activity and productivity in teaching and (2) analyzed the purposes and progress of those systems. Among the reasons articulated for developing these systems, the most common was to identify a "rational" method for distributing funds to departments. More generally, institutions wanted to emphasize the importance of the school's educational mission. The schools varied in the types of information they tracked, ranging from a selective focus on medical school education to a comprehensive assessment of teaching activity and educational administration, committee work, and advising. Schools were almost evenly split between those that used a relative-value-unit method of tracking activity and those that used a contact-hour method. This study also identified six challenges that the institutions encountered with these metric systems: (1) the lack of a culture of data in management; (2) skepticism of faculty and chairs; (3) the misguided search for one perfect metric; (4) the expectation that a metric system will erase ambiguity regarding faculty teaching contributions; (5) the lack of, and difficulty with developing, measures of quality; and (6) the tendency to become overly complex. Because of the concern about the teaching mission at medical schools, the number of institutions developing educational metric systems will likely increase in the coming years. By documenting and accounting financially for teaching, medical schools can ensure that the educational mission is valued and appropriately supported.

  1. Future growth in the gamma sterilization of disposable medical products (DMPs)

    An estimated 361 million cubic feet (10 million cubic meters) of disposable medical products and related health care items are currently being sterilized around the world. Ethylene oxide gas is used to treat approximately 252 million cubic feet (7.1 million cubic meters), gamma radiation is used to sterilize approximately 99 million cubic feet (2.8 million cubic meters), and electron beam is used on approximately 10 million cubic feet (0.3 million cubic meters) of disposable medical products (DMPs). Market share for each of these terminal cold sterilization processes are 70%, 27%, and 3% respectively. There are a number of factors which are affecting the overall growth of the market. The most important factors are summarized. Balancing all of these factors, the pre-sterilized disposable products market is forecasted to grow on average of 5% per year. Gamma radiation is experiencing growth from both general market growth and the introduction of new products, as well as the conversion of product from ethylene oxide (EtO) to cobalt-60 sterilization. Electron beam usage while experiencing good growth in the early 1980s, is predicted to have a flat growth curve during the late 1980s, and then start to experience renewed growth in the mid to late 1990s as two or three new electron beam facilities are built. In the late 1990s other potentially competing technologies are expected to have an impact on the market place. (author)

    The pharmaceutical market in Bangladesh is highly concentrated (top ten control around 70 % of the market). Due to high competition aggressive marketing strategies are adopted for greater market share, which sometimes cross limit. There is lack of data on this aspect in Bangladesh. This exploratory study aimed to fill this gap by investigating current promotional practices of the pharmaceutical companies including the role of their medical representatives (MR). This qualitative study was conducted as part of a larger study to explore the status of governance in health sector in 2009. Data were collected from Dhaka, Chittagong and Bogra districts through in-depth interview (healthcare providers and MRs), observation (physician-MR interaction), and round table discussion (chief executives and top management of the pharmaceutical companies). Findings reveal a highly structured system geared to generate prescriptions and ensure market share instituted by the pharmaceuticals. A comprehensive training curriculum for the MRs prepares the newly recruited science graduates for generating enough prescriptions by catering to the identified needs and demands of the physicians expressed or otherwise, and thus grab higher market-share for the companies they represent. Approaches such as inducements, persuasion, emotional blackmail, serving family members, etc. are used. The type, quantity and quality of inducements offered to the physicians depend upon his/her capacity to produce prescriptions. The popular physicians are cultivated meticulously by the MRs to establish brand loyalty and fulfill individual and company targets. The physicians, willingly or unwillingly, become part of the system with few exceptions. Neither the regulatory authority nor the professional or consumer rights bodies has any role to control or ractify the process. The aggressive marketing of the pharmaceutical companies compel their MRs, programmed to maximize market share, to adopt unethical means if

    Full Text Available Preparing health professionals in health promotion (HP and disease prevention is essential for improvement of population health, community HP, and better health care for individuals. The aim of this article is to describe an HP project in the form of a major self-directed project-based learning task integrated within the curriculum in the second year of the medical degree program at United Arab Emirates University. The project introduces students to public health and HP practice and develops students’ literature searching, writing, presentation skills, and team work. Students learn the principles underlying behavioral change, and the design of HP programs and materials, through a lecture format. Small groups of students each choose a specific health topic for their project. Over 11 weeks, students obtain information about their topic from appropriate sources (library, PubMed, Google Scholar, credible health sources such as World Health Organization. Using the principles learned in the lectures, they develop appropriate materials for their target audience: for example, posters, a pamphlet, social media content, or a video or radio message. Students seek advice from specialist faculty as needed. In week 12, each team presents their project background, rationale, and materials to their colleagues in a seminar format open to all faculty. They then submit the materials they developed for assessment. Group marks are assigned for presentations and materials. Key concepts are assessed by multiple choice questions in comprehensive course examinations. By participation in the HP project, many students develop a solid background in prevention. The information retrieval, writing, and presentation skills, as well as experience of team work, are valuable both for the remaining years of their training and their future careers.

    Full Text Available The constant competitiveness for the interest of entrepreneurs, tourists, students makes that local government units put effort into creating their image. However, the limited capital and organizational resources make that these units initiate multilateral promotion actions. Preparing its offer they repeatedly use attractive place products. The main aim of the article is to answer the question whether, if so in what ways, the Milicz carp, treated as a place product, is used in the promotion of the Local Action Group “Partnership for the Barycz Valley” created by the eight communes of Lower Silesia and Wielkopolskie province. Especially while taking into account two elements: first, the premises of the official strategic documents adopted within ‘the Barycz Valley’, second, the conducted in practice promotion actions. The use of two methods: content analysis and comparative analysis allows to state that the Milicz carp, against the goals in the given documents, plays a significant role in the promotion of the cooperating communes. Actions in the field of public relations have the greatest importance. On the other hand, the actions concerning the promotion of the Milicz carp do not accompany all the enterprises shaping the image of ‘the Barycz Valley’.

    Due to the increasing complexity of medical education and practice, the preparation of healthcare professionals for leadership roles and responsibilities has become increasingly important. To date, the literature on faculty development designed to promote leadership in medical education has not been reviewed in a systematic fashion. The objective of this review is to synthesize the existing evidence that addresses the following question: 'What are the effects of faculty development interventions designed to improve leadership abilities on the knowledge, attitudes, and skills of faculty members in medicine and on the institutions in which they work?' The search, which covered the period 1980-2009, included six databases (Medline, EMBASE, CINAHL, Web of Science, ERIC, and ABI/Inform) and used the following keywords: faculty development; in-service training; doctor; medic; physician; faculty; leadership; management; administration; executive; and change agent. Hand searches were also conducted, and expert recommendations were solicited. Articles with a focus on faculty development to improve leadership, targeting basic science and clinical faculty members, were reviewed. All study designs that included outcome data beyond participant satisfaction were examined. From an initial 687 unique records, 48 articles met the review criteria in three broad categories: (1) reports in which leadership was the primary focus of the intervention; (2) reports in which leadership was a component of a broader focus on educational development; and (3) reports in which leadership was a component of a broader focus on academic career development. Data were extracted by three coders using the standardized Best Evidence Medical Education coding sheet adapted for our use. One reviewer coded all of the articles, and two reviewers each coded half of the dataset. Coding differences were resolved through discussion. Data were synthesized using Kirkpatrick's four levels of educational outcomes

    Full Text Available To prevent ephedrine-related products from being misused to produce amphetamine and/or its analogs, there's a need for more effective and achievable regulatory mechanisms for the health, police, investigational, prosecution and judiciary authorities in Taiwan. This review was conducted to evaluate the international and Taiwan's regulatory policies and management of medical ephedrine-related products through the corresponding information collected from international and Taiwan government agency authorities. The combat of illegal drugs should involve both supply and demand sides to be successful. Health authorities in Taiwan do not have the investigational power to manage the forbidden transformation, abusing and manufacture of the illegal drugs from ephedrine-related products. Take the judicial interventions in the United States and in Japan as the examples, the organizational cooperation in Taiwan can be one of the main key strategies to combat against illegal drugs from ephedrine-related products. It is necessary to integrate the judicial, police and health agencies to prevent the production of illegal drugs from the ephedrine-related products in Taiwan. The efforts and regulatory control measures should be integrated to speed up the collaboration between different government authorities. It might be achieved through reorganization involving Taiwan Food and Drug Administration.

    The Department of Rehabilitation Services, within the University of Maryland Medical Center's 650-bed academic medical center, was experiencing difficulty in meeting productivity standards. Therapists in the outpatient division believed they were not spending enough time performing billable patient care activities. Therapists in the inpatient division had difficulty keeping pace with the volume of incoming referrals. Collectively, these issues caused dissatisfaction among referral sources and frustration among the staff within the rehabilitation department. The department undertook a phased approach to address these issues that included examining the evidence, using Lean process improvement principles, and employing transformational leadership strategies to drive improvements in productivity and efficiency. The lessons learned support the importance of having meaningful metrics appropriate for the patient population served, the use of Lean as an effective tool for improving productivity in rehabilitation departments, the impact of engaging staff at the grassroots level, and the importance of having commitment from leaders. The study findings have implications for not only rehabilitation and hospital leadership, but CEOs and managers of any business who need to eliminate waste or increase staff productivity.

    The principles for selecting the appropriate dose for the radiation sterilization of medical products are set forth, taking into account the initial contamination of the product, the radiation senstivity of contaminants and the required level of reliability of sterilization. The initial contamination level of certain preparations (glucose and radiopharmaceuticals) is established and the radiation sensitivity of the isolated contaminants is determined in terms of Dio indices. Of the microorganisms isolated the most common were staphylococci, streptococci, Gram-negative bacteria, Aspergilli, Penicillia and yeast fungi. Spore-forming types of microorganisms were isolated with a frequency of the order of 10 -2 . The radiation sensitivity in terms of D 10 was established for more than 3000 strains of microorganisms. For 75-85% of the strains the D 10 indices gave 10-40 krad and for 0.2-1% more than 100 krad. The experimental data were subjected to computer analysis which confirmed the adequacy of the techniques used to determine radiosensitivity. The authors then calculated by computer the radiation sterilizing doses for different degrees of initial contamination of the products with reliability coefficients of 10 6 and 10 8 . For sterilizing radiopharmaceuticals and glucose solutions these doses are 0.8-1 Mrad. Verification experiments show that these doses give reliable sterilization of the medical products concerned.

    To determine the scientific production of Research Vice-chancellors at Peruvian universities that have medical schools, as well as their academic degrees as an indirect way to evaluate their suitability for the position they hold. We searched all Peruvian universities that register medical schools. Of these, the scientific production of the universities registered in SCOPUS was identified in September of the 2016. The scientific production of the vice chancellors of investigation of these faculties of medicine was determined through the search of its scientific publications registered in SCOPUS and those reported in the National Registry of Researchers in Science and Technology. Academic degrees were obtained from the database of the National Superintendence of Higher University Education. The sample included 28 research vice chancellors. Only 4/28 had any publications. The average number of articles published by the vice chancellors of research was 1.71, the number of citations 23.1 on average and the H index 0.64. Besides, 22 Vice-chancellors of research had the degree of doctor, four had the degree of bachelor and two the degree of master. The scientific production of research vice chancellors is poor. The required academic grade requirement for the position is not met in all cases. It is likely that, having no research experience, his leadership in directing a university's research policies may be questioned.

    We recently constructed a Bacillus subtilis strain (CCTCC M 2016536) from which we had deleted the srfC, spoIIAC, nprE, aprE and amyE genes. This strain is capable of robust recombinant protein production and amenable to high-cell-density fermentation. Because the promoter is among the factors that influence the production of target proteins, optimization of the initial promoter, P amyQ from Bacillus amyloliquefaciens, should improve protein expression using this strain. This study was undertaken to develop a new, high-level expression system in B. subtilis CCTCC M 2016536. Using the enzyme β-cyclodextrin glycosyltransferase (β-CGTase) as a reporter protein and B. subtilis CCTCC M 2016536 as the host, nine plasmids equipped with single promoters were screened using shake-flask cultivation. The plasmid containing the P amyQ' promoter produced the greatest extracellular β-CGTase activity; 24.1 U/mL. Subsequently, six plasmids equipped with dual promoters were constructed and evaluated using this same method. The plasmid containing the dual promoter P HpaII -P amyQ' produced the highest extracellular β-CGTase activity (30.5 U/mL) and was relatively glucose repressed. The dual promoter P HpaII -P amyQ' also mediated substantial extracellular pullulanase (90.7 U/mL) and α-CGTase expression (9.5 U/mL) during shake-flask cultivation, demonstrating the general applicability of this system. Finally, the production of β-CGTase using the dual-promoter P HpaII -P amyQ' system was investigated in a 3-L fermenter. Extracellular expression of β-CGTase reached 571.2 U/mL (2.5 mg/mL), demonstrating the potential of this system for use in industrial applications. The dual-promoter P HpaII -P amyQ' system was found to support superior expression of extracellular proteins in B. subtilis CCTCC M 2016536. This system appears generally applicable and is amenable to scale-up.

    It is important that heart failure (HF) patients adhere to their medication regimen and engage in physical activity. Evidence shows that adherence to these HF self-management behaviors can be improved with appropriate interventions. To further promote medication adherence and physical activity among HF patients, we developed an intervention for hospitalized HF patients. The intervention mapping protocol was applied in the development of the intervention. This entailed performing a needs assessment, defining change objectives, selecting determinants and strategies, and developing the materials. The resulting intervention, Motivate4Change, makes use of interactive technology and provides HF patients with personalized feedback and advice. Specific change objectives were defined. The relevant behavioral determinants for the physical activity program were practical knowledge on physical activity performance and self-efficacy for, and perceived benefits of, physical activity. For medication-taking, the selected determinants were practical knowledge on medication-taking, perceived barriers to medication-taking, beliefs about the necessity and harm regarding the medication prescribed, and beliefs about overprescribing and harm of medication in general. The change objectives and behavior change determinants were translated in feedback and advice strategies in an interactive technology program that included tailored feedback and advice, and role models in videos in which the behaviors and overcoming barriers were demonstrated. Relevant stakeholders were involved in the interventions development process. The intervention was pretested among HF patients and adjustments were made accordingly. The interactive technology physical activity and medication adherence promotion program for hospitalized HF patients was systematically developed using the intervention mapping protocol and was based on the available theory and evidence regarding HF self-management behavior change.

    Emotions--one's own and others'--play a large role in the lives of medical students. Students must deal with their emotional reactions to intellectual and physical stress, the demanding clinical situations to which they are witness, as well as patients' and patients' family members' often intense feelings. Yet, currently few components in formal medical training--in either direct curricular instruction or physician role modeling--focus on the emotional lives of students. In this article, the author examines patients', medical students', and physician role models' emotions in the clinical context, highlighting challenges in all three of these arenas. Next, the author asserts that the preponderance of medical education continues to address the emotional realm through ignoring, detaching from, and distancing from emotions. Finally, she presents not only possible theoretical and conceptual models for developing ways of understanding, attending to, and ultimately "working with" emotions in medical education but also examples of innovative curricular efforts to incorporate emotional awareness into medical student training. The author concludes with the hope that medical educators will consider making a concerted effort to acknowledge emotions and their importance in medicine and medical training.

Reactor physics experiments and material research will be carried out using the capabilities of this facility. The United States of America and Ukraine have started collaboration activity for developing a conceptual design for this facility with low enrichment uranium (LEU) fuel. Different conceptual designs are being developed based on the facility mission and the engineering requirements including nuclear physics, neutronics, heat transfer, thermal hydraulics, structure, and material issues. Different fuel designs with LEU and reflector materials are considered in the design process. Safety, reliability, and environmental considerations are included in the facility conceptual design. The facility is configured to accommodate future design improvements and upgrades. This report is a part of the Argonne National Laboratory Activity within this collaboration for developing and characterizing the subcritical assembly conceptual design. In this study, the medical isotope production function of the Kharkov facility is defined. First, a review was carried out to identify the medical isotopes and its medical use. Then a preliminary assessment was performed without including the self-shielding effect of the irradiated samples. Finally, more detailed investigation was carried out including the self-shielding effect, which defined the sample size and irradiation location for producing each medical isotope. In the first part, the reaction rates were calculated as the multiplication of the cross section with the unperturbed neutron flux of the facility. Over fifty isotopes were considered and all transmutation channels are used including (n,{gamma}), (n,2n), (n,p), and ({gamma},n). In the second part

    The Medical Isotope Production Reactor (MIPR) is an aqueous solution of uranyl nitrate in water, contained in an aluminum cylinder immersed in a large pool of water which can provide both shielding and a medium for heat exchange. The control rods are inserted at the top through re-entrant thimbles. Provision is made to remove radiolytic gases and recombine emitted hydrogen and oxygen. Small quantities of the solution can be continuously extracted and replaced after passing through selective ion exchange columns, which are used to extract the desired products (fission products), e.g. molybdenum-99. This reactor type is known for its large negative temperature coefficient, the small amount of fuel required for criticality, and the ease of control. Calculation using TWODANT show that a 20% U-235 enriched system, water reflected can be critical with 73 liters of solution.

    With the continuous incorporation of health technologies, hospital risk management should be implemented to systemize the monitoring of adverse effects, performing actions to control and eliminate their damage. As part of these actions, Technovigilance is active in the procedures of acquisition, use and quality control of health products and equipment. This study aimed to construct and validate an instrument to evaluate medical-hospital products. This is a quantitative, exploratory, longitudinal and methodological development study, based on the Six Sigma quality management model, which has as its principle basis the component stages of the DMAIC Cycle. For data collection and content validation, the Delphi technique was used with professionals from the Brazilian Sentinel Hospital Network. It was concluded that the instrument developed permitted the evaluation of the product, differentiating between the results of the tested brands, in line with the initial study goal of qualifying the evaluations performed.

    The effects of Bacillus sp. SLS18, a plant-growth-promoting endophyte, on the biomass production and Mn/Cd uptake of sweet sorghum (Sorghum bicolor L.), Phytolacca acinosa Roxb., and Solanum nigrum L. were investigated. SLS18 displayed multiple heavy metals and antibiotics resistances. The strain also exhibited the capacity of producing indole-3-acetic acid, siderophores, and 1-aminocyclopropane-1-carboxylic acid deaminase. In pot experiments, SLS18 could not only infect plants effectively but also significantly increase the biomass of the three tested plants in the presence of Mn/Cd. The promoting effect order of SLS18 on the biomass of the tested plants was sweet sorghum > P. acinosa > S. nigrum L. In the presence of Mn (2,000 mg kg{sup -1}) and Cd (50 mg kg{sup -1}) in vermiculite, the total Mn/Cd uptakes in the aerial parts of sweet sorghum, P. acinosa, and S. nigrum L. were increased by 65.2%/40.0%, 55.2%/31.1%, and 18.6%/25.6%, respectively, compared to the uninoculated controls. This demonstrates that the symbiont of SLS18 and sweet sorghum has the potential of improving sweet sorghum biomass production and its total metal uptake on heavy metal-polluted marginal land. It offers the potential that heavy metal-polluted marginal land could be utilized in planting sweet sorghum as biofuel feedstock for ethanol production, which not only gives a promising phytoremediation strategy but also eases the competition for limited fertile farmland between energy crops and food crops.

    To bring the benefits of science more quickly to patient care, the NIH National Center Advancing Translational Sciences (NCATS) supports programs that enhance the development, testing, and implementation of new medical products and procedures. The NCATS clinical and translational science award (CTSA) program is central to that mission; creating an academic home for clinical and translational science and supporting those involved in the discovery and development of new health-related inventions. The technology transfer Offices (TTO) of CTSA-funded universities can be important partners in the development process; facilitating the transfer of medical research to the commercial sector for further development and ultimately, distribution to patients. The Aggregating Intellectual Property (IP) Working Group (AWG) of the CTSA public private partnerships key function committee (PPP-KFC) developed a survey to explore how CTSA-funded institutions currently interface with their respective TTOs to support medical product development. The results suggest a range of relationships across institutions; approximately half have formal collaborative programs, but only a few have well-connected programs. Models of collaborations are described and provided as examples of successful CTSA/TTO partnerships that have increased the value of health-related inventions as measured by follow-on funding and industry involvement; either as a consulting partner or licensee. © 2014 Wiley Periodicals, Inc.

    Condom use is the best available strategy to prevent HIV infection during sexual intercourse. However, since many people choose not to use condoms in circumstances in which HIV risk exists, alternatives to condom use for HIV prevention are needed. Currently there are several alternative bio-medical HIV-prevention products in different stages of development: microbicides, vaccines, post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP). Seventy-two men who have sex with men (MSM) who took part in a study on Internet use and intentional condomless anal intercourse were asked about these four products during a semi-structured interview. The questions explored knowledge and acceptability of all the products and willingness to participate in microbicide and vaccine trials. Qualitative analysis of the data suggests that these men had virtually no knowledge of PrEP, very limited knowledge of microbicides, some information about PEP and considerably more knowledge about vaccines. Reactions towards the products were generally positive except for PrEP, for which reactions were polarized as either enthusiastic or negative. With the exception of PrEP, many men expressed willingness to use the products in the future. Most men would be willing to participate in trials for microbicides and vaccines if given basic reassurances. Concerns over negative side effects and preoccupation with possible infection were some of the motives given for non-willingness to participate in a vaccine trial. These results should inform the development of future trials of biomedical prevention products.

The Ecomark scheme was launched in 1991, however the Ecomark label currently remains a nonstarter, with little awareness and no real consumer demand. India......Ecolabels are used to give consumers information about the environmental impact of products and thereby give an informed choice and an incentive to the consumer to choose the ecolabelled product. The environmental effectiveness of ecolabels ultimately relies on consumers’ willingness to pay extra...... for a product with a lower environmental impact than alternative products. Various ecolabels exist throughout the world, but the difference between the successful and the non-effective ecolabels is large. This paper compares a best practice example of an ecolabel with a less successful ecolabel – each belonging...

    We have previously demonstrated that both canine and human OSA cell lines, as well as 8 fresh canine OSA tumor samples, exhibit constitutive phosphorylation of STAT3, and that this correlates with enhanced expression of matrix metalloproteinase-2 (MMP2). While multiple signal transduction pathways can result in phosphorylation of STAT3, stimulation of the cytokine receptor gp130 through either IL-6 or Oncostatin M (OSM) is the most common mechanism through which STAT3 is activated. The purpose of this study was to evaluate the role of IL-6 and OSM stimulation on both canine and human OSA cell lines to begin to determine the role of these cytokines in the biology of OSA. RT-PCR and Western blotting were used to interrogate the consequences of OSM and IL-6 stimulation of OSA cell lines. OSA cells were stimulated with OSM and/or hepatocyte growth factor (HGF) and the effects on MMP2 activity (gel zymography), proliferation (CyQUANT), invasion (Matrigel transwell assay), and VEGF production (Western blotting, ELISA) were assessed. The small molecule STAT3 inhibitor LLL3 was used to investigate the impact of STAT3 inhibition following OSM stimulation of OSA cells. Our data demonstrate that the OSM receptor (OSMR), but not IL-6 or its receptor, is expressed by all human and canine OSA cell lines and canine OSA tumor samples; additionally, OSM expression was noted in all tumor samples. Treatment of OSA cell lines with OSM induced phosphorylation of STAT3, Src, and JAK2. OSM stimulation also resulted in a dose dependent increase in MMP2 activity and VEGF expression that was markedly reduced following treatment with the small molecule STAT3 inhibitor LLL3. Lastly, OSM stimulation of OSA cell lines enhanced invasion through Matrigel, particularly in the presence of rhHGF. In contrast, both OSM and HGF stimulation of OSA cell lines did not alter their proliferative capacity. These data indicate OSM stimulation of human and canine OSA cells induces STAT3 activation, thereby

    Full Text Available This study presents the medical radioisotope production performance of a conceptual accelerator driven system (ADS. Lead-bismuth eutectic (LBE is selected as target material. The subcritical fuel core is conceptually divided into ten equidistant subzones. The ceramic (natural U, PuO2 fuel mixture and the materials used for radioisotope production (copper, gold, cobalt, holmium, rhenium, thulium, mercury, palladium, thallium, molybdenum, and yttrium are separately prepared as cylindrical rods cladded with carbon/carbon composite (C/C and these rods are located in the subzones. In order to obtain the flattened power density, percentages of PuO2 in the mixture of UO2 and PuO2 in the subzones are adjusted in radial direction of the fuel zone. Time-dependent calculations are performed at 1000 MW thermal fission power (Pth for one hour using the BURN card. The neutronic results show that the investigated ADS has a high neutronic capability, in terms of medical radioisotope productions, spent fuel transmutation and energy multiplication. Moreover, a good quasiuniform power density is achieved in each material case. The peak-to-average fission power density ratio is in the range of 1.02–1.28.

    Arabidopsis promoters of genes BANYULS and FRUITFULL are transcribed in Camelina. They triggered the transcription of limonene synthase and induced higher limonene production in seeds and fruits than CaMV 35S promoter. Camelina sativa (Camelina) is an oilseed crop of relevance for the production of biofuels and the plant has been target of a recent and intense program of genetic manipulation aimed to increase performance, seed yield and to modify the fatty acid composition of the oil. Here, we have explored the performance of two Arabidopsis thaliana (Arabidopsis) promoters in triggering transgene expression in Camelina. The promoters of two genes BANYULS (AtBAN pro ) and FRUITFULL (AtFUL pro ), which are expressed in seed coat and valves of Arabidopsis, respectively, have been chosen to induce the expression of limonene synthase (LS) from Citrus limon. In addition, the constitutive CaMV 35S promoter was utilized to overexpress LS in Camelina . The results of experiments revealed that AtBAN pro and AtFUL pro are actively transcribed in Camelina where they also retain specificity of expression in seeds and valves as previously observed in Arabidopsis. LS induced by AtBAN pro and AtFUL pro leads to higher limonene production in seeds and fruits than when the CaMV 35S was used to trigger the expression. In conclusion, the results of experiments indicate that AtBAN pro and AtFUL pro can be successfully utilized to induce the expression of the transgenes of interest in seeds and fruits of Camelina.

    Pressure on physicians to increase productivity is rising in parallel with administrative tasks, regulations, and the use of electronic health records (EHRs). Physician extenders and clinical pathways are already in use to increase productivity and reduce costs and burnout, but other strategies are required. We evaluated whether implementation of medical scribes in an academic urology clinic would affect productivity, revenue, and patient/provider satisfaction. Six academic urologists were assigned scribes for 1 clinic day per week for 3 months. Likert-type patient and provider surveys were developed to evaluate satisfaction with and without scribes. Matched clinic days in the year prior were used to evaluate changes in productivity and physician/hospital charges and revenue. After using scribes for 3 months, providers reported increased efficiency (p value = 0.03) and work satisfaction (p value = 0.03), while seeing a mean 2.15 more patients per session (+ 0.96 return visits, + 0.99 new patients, and + 0.22 procedures), contributing to an additional 2.6 wRVUs, $542 in physician charges, and $861 in hospital charges per clinic session. At a gross collection rate of 36%, actual combined revenue was + $506/session, representing a 26% increase in overall revenue. At a cost of $77/session, the net financial impact was + $429 per clinic session, resulting in a return-to-investment ratio greater than 6:1, while having no effect on patient satisfaction scores. Additionally, with scribes, clinic encounters were closed a mean 8.9 days earlier. Implementing medical scribes in academic urology practices may be useful in increasing productivity, revenue, and provider satisfaction, while maintaining high patient satisfaction.

    The use of Aqueous Homogenous Reactors (AHR) is one of the most promissory alternatives to produce medical isotopes, mainly "9"9Mo. Compare to multipurpose research reactors, an AHR dedicated for "9"9Mo production has advantages because of their low cost, small critical mass, inherent passive safety, and simplified fuel handling, processing, and purification characteristics. This article presents the current state of research in our working group on this topic. Are presented and discussed the group validation efforts with benchmarking exercises that include neutronic and thermal-hydraulic results of two solution reactors, the SUPO and ARGUS reactors. Neutronic and thermal-hydraulic results of 75 kWth AHR based on the ARGUS reactor LEU configuration are presented. The neutronic studies included the determination of parameters such as reflector thickness, critical height, medical isotopes production and others. Thermal-hydraulics studies were focused on demonstrating that sufficient cooling capacity exists to prevent fuel overheating. In addition, the effects of some calculation parameters on the computational modeling of temperature, velocity and gas volume fraction during steady-state operation of an AHR are discussed. The neutronic and thermal-hydraulics studies have been performed with the MCNPX version 2.6e computational code and the version 14 of ANSYS CFX respectively. Our group studies and the results obtained contribute to demonstrate the feasibility of using AHR for the production of medical isotopes, however additional studies are still necessary to confirm these results and contribute to development and demonstration of their technical, safety, and economic viability.

    We have characterized the intronic promoter of the rat estrogen receptor (ER) alpha gene, responsible for the lactotrope-specific truncated ER product (TERP)-1 isoform expression. Transcriptional regulation was investigated by transient transfections using 5'-deletion constructs. TERP promoter constructs were highly active in MMQ cells, a pure lactotrope cell line, whereas a low basal activity was detected in alphaT3-1 gonadotrope cells or in COS-7 monkey kidney cells. Serial deletion analysis revealed that 1) a minimal -693-bp region encompassing the TATA box is sufficient to allow lactotrope-specific expression; 2) the promoter contains strong positive cis-acting elements both in the distal and proximal regions, and 3) the region spanning the -1698/-1194 region includes repressor elements. Transient transfection studies, EMSAs, and gel shifts demonstrated that estrogen activates the TERP promoter via an estrogen-responsive element (ERE1) located within the proximal region. Mutation of ERE1 site completely abolishes the estradiol-dependent transcription, indicating that ERE1 site is sufficient to confer estrogen responsiveness to TERP promoter. In addition, ERalpha action was synergized by transfection of the pituitary-specific factor Pit-1. EMSAs showed that a single Pit-1 DNA binding element in the vicinity of the TATA box is sufficient to confer response by the TERP promoter. In conclusion, we demonstrated, for the first time, that TERP promoter regulation involves ERE and Pit-1 cis-elements and corresponding trans-acting factors, which could play a role in the physiological changes that occur in TERP-1 transcription in lactotrope cells.

    For the low enriched aqueous homogeneous reactor to be economic in the production of medical isotopes, such as Mo-99 and Sr-89, the power level should be of the order of 100 kWth. This is double the earlier designs and this paper discusses the design changes which must be considered to meet this goal. The topics considered are: 1. Heat removal from the reactor solution; 2. Recombination of radiolytic gases; 3. Adequate radiation shielding; 4. Stability of reactor power with fluctuating reactivity; 5. Adequate cooling of the reflector; 6. Independent shutdown mechanisms; 7. Required volume of the reactor; 8. Economic implementation. (author)

    Full Text Available Background: Work is an important source for establishing livelihoods and social occasions; however, it can also damage on person's health. The aim of the present study was to study of association between health locus of control and health promoting behaviors among employees of Bushehr University of Medical Sciences. Materials and Methods: This cross-sectional study was conducted on 208 employees of Bushehr University of Medical Sciences by using convenience sampling method. Data were collected by using standard questionnaires of health-promoting lifestyle and multidimensional health locus of control. Data analysis done by SPSS software version 20. Descriptive indicators and linear regression test was used. Results: Among regression models which related to health promoting behavior and its six dimensions, only there was a significant association between total behavior, physical activity and interpersonal relationship dimensions. Between demographic factors and health locus of control only internal health locus of control explained the health promoting behavior and it explained health promoting behavior changes  within 3.2% (R2=3.2%. None of the three health locus of control explained physical activity dimensions, while internal health locus of control explained interpersonal relation dimension positively and chance locus of control explained interpersonal relation dimension negatively and explained interpersonal relation changes within 4.9% (R2=4.9%. Conclusion: Due to the effect of internal health locus of control on health promotion behavior and interpersonal relationships, we should try to internalize locus of control by performing counseling programs to step toward improving employee health by improving behaviors related to health.

  19. Review of the Code of Practice for the Radiosterilization of Medical Products

    The background of the IAEA recommendations for a Code of Practice is outlined. The possibility of laying down broad safety margins based on scientific foresight and detailed advanced planning will serve to guide the rapidly accelerating acceptance of radiosterilization by industry, especially in those firms producing supplies for use in medicine and surgery. Production control should be attuned to the scientific and technological advances, and it is becoming clear that the focus of control should be moved away from sterility testing of the finished products to hygienic and sterile operations during the manufacturing operations themselves. The contamination of the product before sterilization should already have been kept to a minimum, and this pre-sterilization level of contamination should be regularly recorded using bacteriological tests. The choice of dosage should be based on average pre-sterilization counts and the inactivation factors found desirable for die intended use of the product. On commissioning, or whenever an existing process is altered, the efficiency of the irradiation facility must be tested using microbiological reference standards. The margin of safety should be checked by using deliberately contaminated articles. However, the backbone of the control procedures must still be dosimetry. The preparation of a Code of Practice for the Radiosterilization of Medical Products will constitute a challenge to operators working with other sterilizing procedures. (author)

    Full Text Available We conducted a pilot qualitative and quantitative assessment of residual isocyanates and their potential initial exposures in neonates, as little is known about their contact effect. After a neonatal intensive care unit (NICU stockroom inventory, polyurethane (PU and PU foam (PUF devices and products were qualitatively evaluated for residual isocyanates using Surface SWYPE ™ . Those containing isocyanates were quantitatively tested for methylene diphenyl diisocyanate (MDI species, using UPLC-UV-MS/MS method. Ten of 37 products and devices tested, indicated both free and bound residual surface isocyanates; PU/PUF pieces contained aromatic isocyanates; one product contained aliphatic isocyanates. Overall, quantified mean MDI concentrations were low (4,4‘-MDI = 0.52 to 140.1 pg/mg and (2,4‘-MDI = 0.01 to 4.48 pg/mg. The 4,4‘-MDI species had the highest measured concentration (280 pg/mg. Commonly used medical devices/products contain low, but measurable concentrations of residual isocyanates. Quantifying other isocyanate species and neonatal skin exposure to isocyanates from these devices and products requires further investigation.

    Sarcolemmal ATP-sensitive potassium (K{sub ATP}) channels control skeletal muscle energy use through their ability to adjust membrane excitability and related cell functions in accordance with cellular metabolic status. Mice with disrupted skeletal muscle K{sub ATP} channels exhibit reduced adipocyte size and increased fatty acid release into the circulation. As yet, the molecular mechanisms underlying this link between skeletal muscle K{sub ATP} channel function and adipose mobilization have not been established. Here, we demonstrate that skeletal muscle-specific disruption of K{sub ATP} channel function in transgenic (TG) mice promotes production and secretion of musclin. Musclin is a myokine with high homology to atrial natriuretic peptide (ANP) that enhances ANP signaling by competing for elimination. Augmented musclin production in TG mice is driven by a molecular cascade resulting in enhanced acetylation and nuclear exclusion of the transcription factor forkhead box O1 (FOXO1) – an inhibitor of transcription of the musclin encoding gene. Musclin production/secretion in TG is paired with increased mobilization of fatty acids and a clear trend toward increased circulating ANP, an activator of lipolysis. These data establish K{sub ATP} channel-dependent musclin production as a potential mechanistic link coupling “local” skeletal muscle energy consumption with mobilization of bodily resources from fat. Understanding such mechanisms is an important step toward designing interventions to manage metabolic disorders including those related to excess body fat and associated co-morbidities. - Highlights: • ATP-sensitive K{sup +} channels regulate musclin production by skeletal muscles. • Lipolytic ANP signaling is promoted by augmented skeletal muscle musclin production. • Skeletal muscle musclin transcription is promoted by a CaMKII/HDAC/FOXO1 pathway. • Musclin links adipose mobilization to energy use in K{sub ATP} channel deficient skeletal muscle.

    Sarcolemmal ATP-sensitive potassium (K_A_T_P) channels control skeletal muscle energy use through their ability to adjust membrane excitability and related cell functions in accordance with cellular metabolic status. Mice with disrupted skeletal muscle K_A_T_P channels exhibit reduced adipocyte size and increased fatty acid release into the circulation. As yet, the molecular mechanisms underlying this link between skeletal muscle K_A_T_P channel function and adipose mobilization have not been established. Here, we demonstrate that skeletal muscle-specific disruption of K_A_T_P channel function in transgenic (TG) mice promotes production and secretion of musclin. Musclin is a myokine with high homology to atrial natriuretic peptide (ANP) that enhances ANP signaling by competing for elimination. Augmented musclin production in TG mice is driven by a molecular cascade resulting in enhanced acetylation and nuclear exclusion of the transcription factor forkhead box O1 (FOXO1) – an inhibitor of transcription of the musclin encoding gene. Musclin production/secretion in TG is paired with increased mobilization of fatty acids and a clear trend toward increased circulating ANP, an activator of lipolysis. These data establish K_A_T_P channel-dependent musclin production as a potential mechanistic link coupling “local” skeletal muscle energy consumption with mobilization of bodily resources from fat. Understanding such mechanisms is an important step toward designing interventions to manage metabolic disorders including those related to excess body fat and associated co-morbidities. - Highlights: • ATP-sensitive K"+ channels regulate musclin production by skeletal muscles. • Lipolytic ANP signaling is promoted by augmented skeletal muscle musclin production. • Skeletal muscle musclin transcription is promoted by a CaMKII/HDAC/FOXO1 pathway. • Musclin links adipose mobilization to energy use in K_A_T_P channel deficient skeletal muscle.

    Full Text Available In this work, the modification of Ni/SBA-16 oxygen carrier (OC with yttrium promoter is investigated. The yttrium promoted Ni-based oxygen carrier was synthesized via co-impregnation method and applied in chemical looping steam methane reforming (CL-SMR process, which is used for the production of clean energy carrier. The reaction temperature (500–750 °C, Y loading (2.5–7.4 wt. %, steam/carbon molar ratio (1–5, Ni loading (10–30 wt. % and life time of OCs over 16 cycles at 650 °C were studied to investigate and optimize the structure of OC and process temperature with maximizing average methane conversion and hydrogen production yield. The synthesized OCs were characterized by multiples techniques. The results of X-ray powder diffraction (XRD and energy dispersive X-ray spectroscopy (EDX of reacted OCs showed that the presence of Y particles on the surface of OCs reduces the coke formation. The smaller NiO species were found for the yttrium promoted OC and therefore the distribution of Ni particles was improved. The reduction-oxidation (redox results revealed that 25Ni-2.5Y/SBA-16 OC has the highest catalytic activity of about 99.83% average CH4 conversion and 85.34% H2 production yield at reduction temperature of 650 °C with the steam to carbon molar ratio of 2.

    One of the reasons for rising health care costs is medical errors, a majority of which result from faulty systems and processes. Health care in the past has used process-based initiatives such as Total Quality Management, Continuous Quality Improvement, and Six Sigma to reduce errors. These initiatives to redesign health care, reduce errors, and improve overall efficiency and customer satisfaction have had moderate success. Current trend is to apply the successful Toyota Production System (TPS) to health care since its organizing principles have led to tremendous improvement in productivity and quality for Toyota and other businesses that have adapted them. This article presents insights on the effectiveness of TPS principles in health care and the challenges that lie ahead in successfully integrating this approach with other quality initiatives.

    The negative impact of medical school on students' general and mental health has often been reported. Compared to students of other subjects, or employed peers, medical students face an increased risk of developing depression, anxiety and burnout. While pathogenetic factors have been studied extensively, less is known about health-promoting factors for medical students' health. This longitudinal study aims to identify predictors for maintaining good general and mental health during medical education. We report here the design of the study and its baseline results. We initiated a prospective longitudinal cohort study at the University of Lübeck, Germany. Two consecutive classes of students, entering the university in 2011 and 2012, were recruited. Participants will be assessed annually for the duration of their course. We use validated psychometric instruments covering health outcomes (general and mental health) and personality traits, as well as self-developed, pre-tested items covering leisure activities and sociodemographic data. At baseline, compared to students of STEM (science, technology, engineering, and mathematics) subjects (n = 531; 60.8% response rate), a larger proportion of medical students (n = 350; 93.0% response rate) showed good general health (90.9% vs. 79.7%) and a similar proportion was in good mental health (88.3% vs. 86.3%). Medical students scored significantly higher in the personality traits of extraversion, conscientiousness, openness to experience and agreeableness. Neuroticism proved to be a statistically significant negative predictor for mental health in the logistic regression analyses. Satisfaction with life as a dimension of study-related behaviour and experience predicted general health at baseline. Physical activity was a statistically significant predictor for general health in medical students. Baseline data revealed that medical students reported better general and similar mental health compared to STEM students. The annual

    'Marketing messages' are the themes used in advertisements to promote products. We explored the frequency of different marketing messages used in food and alcohol advertisements in UK women's magazines and associations with the type and nutritional content of products promoted. All advertisements for food and alcohol in 108 issues of popular UK monthly women's magazines were identified and text-based marketing messages classified using a bespoke coding framework. This information was linked to existing data on the type (i.e. food group) and nutritional content of advertised products. A total of 2 687 marketing messages were identified in 726 advertisements. Consumer messages such as 'taste' and 'quality' were most frequently found. Marketing messages used in advertisements for food and alcohol were notably different. The relationship between type and nutritional content of products advertised and marketing messages used was not intuitive from a consumer perspective: advertisements for foods 'high in fat and/or sugar' were less likely to use messages related to health, but more likely to use messages emphasizing reduced amounts of specific nutrients. Almost all advertisements included consumer-related marketing messages. Marketing messages used were not always congruent with the type or nutritional content of advertised products. These findings should be considered when developing policy. © The Author 2013. Published by Oxford University Press on behalf of Faculty of Public Health. All rights reserved.

    To establish the pattern of change in individual scientific production over the career of medical researchers. Retrospective cohort based on prospectively collected data in a hospital information system. Multicentre university hospital in France. Two distinct populations of 1835 researchers (full professors vs non-academic physicians) having produced 44 723 publications between 1995 and 2014. Annual number of publications referenced in Medline/PubMed with a sensitivity analysis based on publications as first/last author and in high impact journals. The individual volume of publications was modelled by age using generalised estimating equations adjusted for birth cohort, biomedical discipline and academic position of researchers. Averaged over the whole career, the annual number of publications was 5.28 (95% CI 4.90 to 5.69) among professors compared to 0.82 (95% CI 0.76 to 0.89) among non-academic physicians (pscientific production between 25 and 35 years (adjusted incidence rate ratio 102.20, 95% CI 60.99 to 171.30), a maturation phase with a slower increase from 35 to 50 years (2.10, 95% CI 1.75 to 2.51) until a stabilisation phase with constant production followed by a potential decline at the end of career (0.90, 95% CI 0.77 to 1.06). The non-academic physicians experienced a slower pace of learning curve at the beginning of their careers (42.38, 95% CI 25.37 to 70.81) followed by a smaller increase in the annual number of publications (1.29, 95% CI 1.11 to 1.51). Compared to full professors, non-academic physicians had a poor capacity to publish, indicating a low productivity when medical doctors have limited time or little interest in undertaking research. This finding highlights the potential for rethinking the missions of medical doctors towards an enlargement of scientific prerogatives in favour of progress in global knowledge.

    2010-01-01

    Recent supply disruptions have highlighted the fragility of the supply chain that delivers essential medical isotopes to patients globally. A new and more reliable way of supplying isotopes to Canadians needs to be found. That is why the Government of Canada established the Expert Review Panel on Medical Isotope Production (the Panel) in June 2009. The Government recognizes the relatively long lead times associated with the development of any new source of medical. isotopes. To ensure that appropriate action is taken now for the long term, the Government tasked the Panel with reporting to the Minister. of Natural Resources on its assessment of the most viable options for securing supplies of technetium-99m (Tc99r) for the Canadian health care system over the medium and long term and the actions that may be required by governments and others to facilitate realization of these options. The Panel reported to the Minister of Natural Resources on November 30, 2009. Since then, the Government has been carefully considering the recommendations of the Panel within the context of the broader nuclear and health care landscape. What follows is the Government's response to the Panel's thoughtful, comprehensive and insightful report, including actions that are planned based on its recommendations. (author)

    The purpose of this study was to utilize the Context, Input, Process and Product (CIPP) evaluation model as a comprehensive framework to guide initiating, planning, implementing and evaluating a revised undergraduate medical education programme. The eight-year longitudinal evaluation study consisted of four phases compatible with the four components of the CIPP model. In the first phase, we explored the strengths and weaknesses of the traditional programme as well as contextual needs, assets, and resources. For the second phase, we proposed a model for the programme considering contextual features. During the process phase, we provided formative information for revisions and adjustments. Finally, in the fourth phase, we evaluated the outcomes of the new undergraduate medical education programme in the basic sciences phase. Information was collected from different sources such as medical students, faculty members, administrators, and graduates, using various qualitative and quantitative methods including focus groups, questionnaires, and performance measures. The CIPP model has the potential to guide policy makers to systematically collect evaluation data and to manage stakeholders' reactions at each stage of the reform in order to make informed decisions. However, the model may result in evaluation burden and fail to address some unplanned evaluation questions.

    Cyanobacteria are oxygenic photosynthetic prokaryotes that play important roles in the global carbon cycle. Recently, engineered cyanobacteria capable of producing various small molecules from CO2 have been developed. However, cyanobacteria are seldom considered as factories for producing proteins, mainly because of the lack of efficient strong promoters. Here, we report the discovery and verification of a super-strong promoter P(cpc560), which contains two predicted promoters and 14 predicted transcription factor binding sites (TFBSs). Using P(cpc560), functional proteins were produced at a level of up to 15% of total soluble protein in the cyanobacterium Synechocystis sp. 6803, a level comparable to that produced in Escherichia coli. We demonstrated that the presence of multiple TFBSs in P(cpc560) is crucial for its promoter strength. Genetically transformable cyanobacteria neither have endotoxins nor form inclusion bodies; therefore, P(cpc560) opens the possibility to use cyanobacteria as alternative hosts for producing heterogeneous proteins from CO2 and inorganic nutrients.

    2014-08-01

    The US Food and Drug Administration (FDA) uses rulemaking as one of its primary tools to protect the public health and implement laws enacted by Congress and the president. Because of the many effects that these rules have on social welfare and the economy, the FDA and other executive agencies receive input from the executive branch, the public, and in some cases, the courts, during the process of rulemaking. In this article, we examine the life cycle of FDA regulations concerning medical products and review notable features of the rulemaking process. The current system grants substantial opportunities for diverse stakeholders to participate in and influence how rules are written and implemented. However, the duration, complexity, and adversarial qualities of the rulemaking process can hinder the FDA's ability to achieve its policy and public health goals. There is considerable variation in the level of transparency at different stages in the process, ranging from freely accessible public comments to undisclosed internal agency deliberations. In addition, significant medical product rules are associated with lengthy times to finalization, in some cases for unclear reasons. We conclude by identifying potential areas for reform on the basis of transparency and efficiency. Copyright © 2014 by Duke University Press.

  17. Guidelines for industrial radiation sterilization of disposable medical products (Cobalt-60 gamma irradiation)

    International Nuclear Information System (INIS)

    1990-01-01

    This IAEA document is aimed at providing necessary guidance on standards and criteria and assistance to Member States, particularly developing countries, in their attempts to properly set up facilities for industrial radiation sterilization of duly-manufactured medical products by exposure to Co-60 gamma radiation. The contents of the guidelines have therefore been designed, as far as practicable, to reflect the practices and procedures currently employed in the processing of the majority of the radiation-sterilized medical products being produced worldwide. Consequently, this document has attempted to present to its users, for information and for action, all the relevant features of the standard criteria as are currently in existence under the auspices of the various authoritative national and/or regional Codes or Guides. The potential user(s) from Member States are expected to freely decide which of the various standards as enumerated in the Guidelines document should be considered for inclusion or exclusion either partially or totally in the context of the formulation of their own nationally-acceptable guidelines.

    Medical device companies are under growing pressure to provide health-economic evaluations of their products. Cost-effectiveness analyses are commonly undertaken as a one-off exercise at the late stage of development of new technologies; however, the benefits of an iterative use of economic evaluation during the development process of new products have been acknowledged in the literature. Furthermore, the use of Bayesian methods within health technology assessment has been shown to be of particular value in the dynamic framework of technology appraisal when new information becomes available in the life cycle of technologies. In this study, we set out a methodology to adapt these methods for their application to directly support investment decisions in a commercial setting from early stages of the development of new medical devices. Starting with relatively simple analysis from the very early development phase and proceeding to greater depth of analysis at later stages, a Bayesian approach facilitates the incorporation of all available evidence and would help companies to make better informed choices at each decision point.

    Tides and wind-driven mixing play a major role in promoting post-bloom productivity in subarctic shelf seas. Whether this is also true in the high Arctic remains unknown. This question is particularly relevant in a context of increasing Arctic Ocean stratification in response to global climatic change. We have used a three-dimensional ocean-sea ice-plankton ecosystem model to assess the contribution of tides and strong wind events to summer (June-August 2001) primary production in the Barents Sea. Tides are responsible for 20% (60% locally) of the post-bloom primary production above Svalbard Bank and east of the Kola Peninsula. By contrast, more than 9% of the primary production is due to winds faster than 8 m s -1 in the central Barents Sea. Locally, this contribution reaches 25%. In the marginal ice zone, both tides and wind events have only a limited effect on primary production (central Barents Sea), respectively. When integrated over all Barents Sea sub-regions, tides and strong wind events account, respectively, for 6.8% (1.55 Tg C; 1 Tg C=10 12 g C) and 4.1% (0.93 Tg C) of the post-bloom primary production (22.6 Tg C). To put this in context, this contribution to summer primary production is equivalent to the spring bloom integrated over the Svalbard area. Tides and winds are significant drivers of summer plankton productivity in the Barents Sea.

    Objective To test whether overweight or obese employees who achieve clinically significant weight loss of 5% or greater have reduced medical expenditures, absenteeism, presenteeism, and/or improved Health-Related Quality Of Life (HRQOL). Methods The sample analyzed combines data from full-time overweight or obese employees who took part in one of the WAY to Health weight loss studies: one that took place in 17 community colleges (935 employees) and another in 12 universities (933), all in North Carolina. The estimations are performed using non-linear difference-in-difference models where groups are identified by whether the employee achieved a 5% or greater weight loss (treated) or not (control) and the treatment variable indicates pre- and post-weight loss intervention. The outcomes analyzed are the average quarterly (90 days) amount of medical claims paid by the health insurer, number of days missed at work during the past month, Stanford Presenteeism Scale SPS-6 and the EQ-5D-3L measure of HRQOL. Results We find statistical evidence supporting that 5% or greater weight loss prevents deterioration in EQ-5D-3L scores by 0.026 points (p-value: 0.03) and reduces both absenteeism by 0.258 days per month (p-value: 0.093) and the likelihood of showing low presenteeism (Stanford SPS-6 score between 7 and 9) by 2.9 percentage points (p-value: 0.083). No reduction in medical expenditures was observed. Conclusions Clinically significant weight loss among overweight or obese employees prevents short term deterioration in HRQOL and there is some evidence that employee productivity is increased. We find no evidence of a quick return on investment from reduced medical expenditures, although this may occur over longer periods. PMID:23632594

  1. Study of alternative routes for the production of innovative radionuclides for medical applications

    International Nuclear Information System (INIS)

    Duchemin, Charlotte

    2015-01-01

    Nuclear medicine is a specialty that uses radioactive nuclei for therapy or diagnosis of diseases such as different types of cancer. These radionuclides are coupled to carrier molecules to target sick cells. Currently, only few isotopes are used in clinical practice. However, many others may be of medical interest due to their emitted radiation and/or their half-life that can be adapted to the carrier molecule transit time and to the pathology. The aim of this PhD thesis is to study the production of innovative radionuclides for therapy and diagnosis applications in collaboration with the GIP ARRONAX, which possesses a multi-particle high energy cyclotron. A fundamental physical parameter to access the production rate of a radionuclide is the production cross section. Experimental data were measured for a selection of radionuclides: photon emitter (Tc-99m) and positron emitter (Sc-44g) for diagnosis, as well as electron emitters (Re-186, Tb-155 and Sn-117m) and α particles emitters (Th-226, Ra-223 and Bi-213) for therapeutic applications. These acquired data are obtained using alternative production routes compared to the commonly used. Data related to the contaminants produced during the irradiations were also extracted. The experimental cross section values are compared with theoretical model predictions. The large set of data obtained contributes to the theoretical physicist studies allowing to constrain their models to improve and/or validate them. (author)

    Nuclear medicine is a field which requires precise decay data for use in planning radionuclide production and in imaging and therapeutic applications. To address deficiencies in decay data, sources of medical isotopes were produced and purified at the Brookhaven Linear Isotope Producer (BLIP) then shipped to Argonne National Laboratory where high-precision, gamma-ray measurements were performed using Gammasphere. New decay schemes for a number of PET isotopes and the impact on dose calculations will be presented. To investigate the production of next-generation theranostic or radiotherapeutic isotopes, cross section measurements with high energy protons have also been explored at BLIP. The 100-200 MeV proton energy regime is relatively unexplored for isotope production, thus offering high discovery potential but at the same time a challenging analysis due to the large number of open channels at these energies. Results of cross sections deduced from Compton-suppressed, coincidence gamma-ray spectroscopy performed at Lowell will be presented, focusing on the production of platinum isotopes by irradiating natural platinum foils with 100 to 200 MeV protons.

    Antimicrobials are extensively used as growth promoters in animal feeds worldwide, but reliable estimates are lacking. We conducted an internet-based survey of commercial chicken and pig feed products officially approved for sale in Vietnam over the period March-June 2015. Information on the antimicrobial contents in feed products, alongside animal production data, was used to estimate in-feed antimicrobial consumption to produce one kilogram of live animal (chicken, pig), as well as to estimate country-wide antimicrobial consumption through animal feeds. A total of 1462 commercial feed formulations were examined. The survey-adjusted estimated antimicrobial contents were 25.7 and 62.3 mg/kg in chicken and pig feeds, respectively. Overall, it was estimated that 77.4 mg [95% CI 48.1-106.8] and 286.6 mg [95% CI 191.6-418.3] of in-feed antimicrobials were used to raise 1 kg of live chicken and pig, respectively. Bacitracin (15.5% feeds), chlortetracycline (11.4%), and enramycin (10.8%) were the most common antimicrobials present in chicken feed formulations, whereas bacitracin (24.8%), chlortetracycline (23.9%), and florfenicol (17.4%) were the most common in pig feed formulations. Overall, 57% of the total quantitative usage consisted of antimicrobials regarded by WHO of importance for human medicine, including amoxicillin, colistin, tetracyclines, neomycin, lincomycin, and bacitracin. These figures confirm a very high magnitude of in-feed consumption of antimicrobials, especially in pig production. Results from this study should encourage further monitoring of antimicrobials used in animal production, and foster discussion about existing policies on inclusion of antimicrobials in animal feed rations.

    Equol has higher biological effects than other isoflavones. However, only about 30-50% of humans possess a microbiota capable of producing equol from dietary daidzein. In recent years, interest has grown in dietary applications to improve equol production in human and other animals. In this study, lactulose was used as a potential equol-promoting prebiotic in vitro. The effect of lactulose on transformation of daidzein into equol by sows' fecal microbiota was investigated. Results showed that lactulose treatment improved bacteria growth parameters, changing the kinetics of fermentation in vitro. Lactulose significantly increased total gas production, T1/2, Tmax, and Rmax. Furthermore, lactulose altered the microflora composition, increased equol production associated with a reduction in the population of methanogen and increased the sulfate-reducing bacteria population during 24 h of incubation. Here, we report for the first time that in a certain condition (sealing or high pressure), via a dihydrodaidzein (DHD) pathway equol might be able to reform to daidzein by further metabolism using lactulose as a substrate.

    Grain legumes are a cost-effective alternative for the animal protein in improving the diets of the poor in South-East Asia and Africa. Legumes, through symbiotic nitrogen fixation, meet a major part of their own N demand and partially benefit the following crops of the system by enriching soil. In realization of this sustainability advantage and to promote pulse production, United Nations had declared 2016 as the "International Year of pulses". Grain legumes are frequently subjected to both abiotic and biotic stresses resulting in severe yield losses. Global yields of legumes have been stagnant for the past five decades in spite of adopting various conventional and molecular breeding approaches. Furthermore, the increasing costs and negative effects of pesticides and fertilizers for crop production necessitate the use of biological options of crop production and protection. The use of plant growth-promoting (PGP) bacteria for improving soil and plant health has become one of the attractive strategies for developing sustainable agricultural systems due to their eco-friendliness, low production cost and minimizing consumption of non-renewable resources. This review emphasizes on how the PGP actinobacteria and their metabolites can be used effectively in enhancing the yield and controlling the pests and pathogens of grain legumes.

    The subcutaneous fat tissue mass gradually decreases with age, and its regulation is a strategy to develop anti-aging compounds to ameliorate the photo-aging of human skin. The adipogenesis of human adipose tissue-mesenchymal stem cells (hAT-MSCs) can be used as a model to discover novel anti-aging compounds. Cinnamomum cassia methanol extracts were identified as adipogenesis-promoting agents by natural product library screening. Cinnamates, the major chemical components of Cinnamomum cassia extracts, promoted adipogenesis in hAT-MSCs. We synthesized kojyl cinnamate ester derivatives to improve the pharmacological activity of cinnamates. Structure-activity studies of kojyl cinnamate derivatives showed that both the α,β-unsaturated carbonyl ester group and the kojic acid moiety play core roles in promoting adiponectin production during adipogenesis in hAT-MSCs. We conclude that kojyl cinnamate ester derivatives provide novel pharmacophores that can regulate adipogenesis in hAT-MSCs. Copyright © 2014 Elsevier Ltd. All rights reserved.

  12. Low-Dose Radiation Promotes Dendritic Cell Migration and IL-12 Production via the ATM/NF-KappaB Pathway.

    For dendritic cells (DCs) to initiate an immune response, their ability to migrate and to produce interleukin-12 (IL-12) is crucial. It has been previously shown that low-dose radiation (LDR) promoted IL-12 production by DCs, resulting in increased DC activity that contributed to LDR hormesis in the immune system. However, the molecular mechanism of LDR-induced IL-12 production, as well as the effect of LDR on DC migration capacity require further elucidation. Using the JAWSII immortalized mouse dendritic cell line, we showed that in vitro X-ray irradiation (0.2 Gy) of DCs significantly increased DC migration and IL-12 production, and upregulated CCR7. The neutralizing antibody against CCR7 has been shown to abolish LDR-enhanced DC migration, demonstrating that CCR7 mediates LDR-promoting DC migration. We identified nuclear factor kappaB (NF-κB) as the central signaling pathway that mediated LDR-enhanced expression of IL-12 and CCR7 based on findings that 0.2 Gy X-ray irradiation activated NF-κB, showing increased nuclear p65 translocation and NF-κB DNA-binding activity, while an NF-κB inhibitor blocked LDR-enhanced expression of IL-12 and CCR7, as well as DC migration. Finally, we demonstrated that 0.2 Gy X-ray irradiation promoted ATM phosphorylation and reactive oxygen species generation; however, only the ATM inhibitor abolished the LDR-induced NF-κB-mediated expression of IL-12 and CCR7. Altogether, our data show that exposure to LDR resulted in a hormetic effect on DCs regarding CCR7-mediated migration and IL-12 production by activating the ATM/NF-κB pathway.

    2015-11-01

    Antimicrobial peptides (AMPs) are vital components of the innate immune system of nearly all living organisms. They generally act in the first line of defense against various pathogenic bacteria, parasites, enveloped viruses and fungi. These low molecular mass peptides are considered prospective therapeutic agents due to their broad-spectrum rapid activity, low cytotoxicity to mammalian cells and unique mode of action which hinders emergence of pathogen resistance. In addition to medical use, AMPs can also be employed for development of innovative approaches for plant protection in agriculture. Conferred disease resistance by AMPs might help us surmount losses in yield, quality and safety of agricultural products due to plant pathogens. Heterologous expression in plant-based systems, also called plant molecular farming, offers cost-effective large-scale production which is regarded as one of the most important factors for clinical or agricultural use of AMPs. This review presents various types of AMPs as well as plant-based platforms ranging from cell suspensions to whole plants employed for peptide production. Although AMP production in plants holds great promises for medicine and agriculture, specific technical limitations regarding product yield, function and stability still remain. Additionally, establishment of particular stable expression systems employing plants or plant tissues generally requires extended time scale for platform development compared to certain other heterologous systems. Therefore, fast and promising tools for evaluation of plant-based expression strategies and assessment of function and stability of the heterologously produced AMPs are critical for molecular farming and plant protection.

    Acrylamide is formed in several foods during high-temperature processing. In view of reports written about the neurotoxic, genotoxic and carcinogenic effects of acrylamide, it was considered that the presence of this substance in food products might pose a risk for human health. Currently, according to EU Commission recommendations, the content of acrylamide in food should be monitored. The aim of this work was to analyze the food preferences of youth and students from medical schools in Radom, central-eastern Poland, as the most frequent precipitantsas in the field of food products that may be a significant source of acrylamide in the diet. Furthermore, an attempt was made to determine the level of knowledge of the population in the field of acrylamide. The research was conducted by questionnaire. The study was based on the answers of 227 respondents. The survey was carried out by direct contact with an interviewer from February - June 2012. Analysis of the study population shows that women consume more coffee than men. In addition, adults over 25 years old consumed the largest quantity of coffee; it can therefore be assumed that it is a significant source of acrylamide in their bodies. However, even young people under 17 declared that they consume coffee every day (20%). Due to the adverse effects of this compound it is important to reduce the level of acrylamide in food products. A few people in the population (7%) had heard of acrylamide previously, but none of them had any knowledge of its occurrence and formation. It is necessary to take strong action to change attitudes towards acrylamide and attempt to introduce ways to reduce this compound in the diet, for example, by appropriate selection of products in the daily diet and appropriate means of thermal preparation of products at home.

    Cysteine-rich protein 61 (Cyr61)/CCN1 is a product of an immediate early gene and functions in mediating cell adhesion and inducing cell migration. We previously showed that increased production of Cyr61 by fibroblast-like synoviocytes (FLS) in rheumatoid arthritis (RA) promotes FLS proliferation and participates in RA pathogenesis with the IL-17-dependent pathway. However, whether Cyr61 in turn regulates Th17 cell differentiation and further enhances inflammation of RA remained unknown. In the current study, we explored the potential role of Cyr61 as a proinflammatory factor in RA pathogenesis. We found that Cyr61 treatment dramatically induced IL-6 production in FLS isolated from RA patients. Moreover, IL-6 production was attenuated by Cyr61 knockdown in FLS. Mechanistically, we showed that Cyr61 activated IL-6 production via the αvβ5/Akt/NF-κB signaling pathway. Further, using a coculture system consisting of purified CD4(+) T cells and RA FLS, we found that RA FLS stimulated Th17 differentiation, and the pro-Th17 differentiation effect of RA FLS can be attenuated or stimulated by Cyr61 RNA interference or addition of exogenous Cyr61, respectively. Finally, using the collagen-induced arthritis animal model, we showed that treatment with the anti-Cyr61 mAb led to reduction of IL-6 levels, decrease of Th17 response, and attenuation of inflammation and disease progression in vivo. Taken together, our results reveal a novel role of Cyr61 in promoting Th17 development in RA via upregulation of IL-6 production by FLS, thus adding a new layer into the functional interplay between FLS and Th17 in RA pathogenesis. Our study also suggests that targeting of Cyr61 may represent a novel strategy in RA treatment.

    ISO26000:2010 International Guidance Standard on Organizational Social Responsibility requires that effective organizational performance recognize social responsibility, including the rights of persons with disabilities (PWD), engage stakeholders and contribute to sustainable development. Millennium Development Goals 2010 notes that the most vulnerable people require special attention, while the World Report on Disability 2011 identifies improved data collection and removal of barriers to rehabilitation as the means to empower PWD. The Assistive Technology Device Classification (ATDC), Assistive Technology Service Method (ATSM) and Matching Person and Technology models provide an evidence-based, standardized, internationally comparable framework to improve data collection and rehabilitation interventions. The ATDC and ATSM encompass and support universal design (UD) principles, and use the language and concepts of the International Classification of Functioning, Disability and Health (ICF). Use ATDC and ICF concepts to differentiate medical, assistive and UD products and technology; relate technology "types" to markets and costs; and support provision of UD products and technologies as sustainable and socially responsible behavior. Supply-side and demand-side incentives are suggested to foster private sector development and commercialization of UD products and technologies. Health and health-related professionals should be knowledgeable of UD principles and interventions.

    The increasing demand for fresh water has forced many countries to use reclaimed wastewater for agricultural purposes. This water contains pharmaceuticals and personal care products (PPCPs) that remain biologically active following passage through wastewater treatment plants. Run-off from farms and contaminated water from treatment facilities exposes aquatic ecosystems to PPCPs. This study examined the effects of PPCPs on a lower trophic organism. Culex quinquefasciatus larvae were reared in water contaminated with environmentally relevant concentrations of common PPCPs. Acetaminophen alone and a mixture of contaminants were found to increase developmental time of larvae. Susceptibility to Bti increased in larvae exposed to antibiotics, acetaminophen, or a mixture of PPCPs. Antibiotics, hormones, and the mixture altered the mosquito bacterial microbiome. Overall, the results indicate that at environmentally relevant concentrations, PPCPs in reclaimed water can have biologically important effects on an ecologically and medically important lower trophic level insect. - Highlights: • Effects of Pharmaceuticals and Personal Care Products on mosquitoes were examined. • Three PPCP treatments increase susceptibility to a common larvicide (Bti). • Acetaminophen and the mixture of PPCPs caused an increase in developmental time. • The holobiome of mosquitoes treated with PPCPs were sequenced. • Three PPCP regimes changed the holobiome of the mosquitoes. - Pharmaceuticals and personal care products, common to reclaimed wastewater, alter the development of mosquitoes. They also alter the whole-body bacterial microbiome

  1. Radioactive Emissions from Fission-Based Medical Isotope Production and Their Effect on Global Nuclear Explosion Detection

    International Nuclear Information System (INIS)

    Bowyer, T.; Saey, P.

    2015-01-01

    The use of medical isotopes, such as Tc-99m, is widespread with over 30 million procedures being performed every year, but the fission-based production of isotopes used for medical procedures causes emissions into the environment. This paper will show that gaseous radioactive isotopes of xenon, such as Xe-133, are released in high quantities, because they have a high fission cross section and they are difficult to scrub from the processes used to produce the medical isotopes due to their largely unreactive nature. Unfortunately, the reasons that large amounts of radioactive xenon isotopes are emitted from isotope production are the same as those that make these isotopes the most useful isotopes for the detection of underground nuclear explosions. Relatively recently, the nuclear explosion monitoring community has established a provisional monitoring network for the Comprehensive Nuclear-Test-Ban Treaty (CTBT) that includes radioactive xenon monitoring as a major component. This community has discovered that emissions from medical isotope production present a more serious problem to nuclear explosion monitoring than thought when the network was first conceived. To address the growing problem, a group of scientists in both the monitoring and the isotope production communities have come together to attempt to find scientific and pragmatic ways to address the emissions problems, recognizing that medical isotope production should not be adversely affected, while monitoring for nuclear explosions should remain effective as isotope production grows, changes, and spreads globally.

    The effects of reaction conditions on the Fischer-Tropsch activity and product distribution of an alkali-earth metal promoted cobalt based catalyst were studied. The influence of the promoter on the reducibility and cobalt particle size was studied by different techniques, including N{sub 2} adsorption, X-ray diffraction, temperature-programmed reduction, temperature-programmed desorption and acid-base titrations. Experiments were carried out on a bench-scale fixed bed reactor and catalysts were prepared by incipient wetness impregnation. It was observed that addition of a small amount of calcium oxide as a promoter (0.6 wt.%) improved the cobalt oxide reducibility and reduced the formation of cobalt-aluminate species. A positive correlation between basicity and particle size was observed. In terms of FTS results, CO conversion and C{sub 5}{sup +} selectivity were found to be enhanced by the addition of this promoter. It was important to note that the addition of calcium shifted the distribution to mainly C{sub 16}-C{sub 18} hydrocarbons fraction, which could be greatly considered for a diesel formulation. Furthermore, the variation of the reaction conditions seemed to influence product distribution in a lesser extent than unpromoted catalyst. Also, a displacement of hydrocarbon distribution to higher molecular weight with decreasing space velocity and temperature was observed. Moreover, the addition of calcium to the cobalt based catalyst was found to greatly maintain selectivity to C{sub 5}{sup +} for a wide range of H{sub 2}/CO molar ratios. 60 refs., 10 figs., 5 tabs.

    2017-11-01

    Full Text Available Assessment has always been an essential component of postgraduate medical education and for many years focused predominantly on various types of examinations. While examinations of medical knowledge and more recently of clinical skills with standardized patients can assess learner capability in controlled settings and provide a level of assurance for the public, persistent and growing concerns regarding quality of care and patient safety worldwide has raised the importance and need for better work-based assessments. Work-based assessments, when done effectively, can more authentically capture the abilities of learners to actually provide safe, effective, patient-centered care. Furthermore, we have entered the era of interprofessional care where effective teamwork among multiple health care professionals is now paramount. Work-based assessment methods are now essential in an interprofessional healthcare world.To better prepare learners for these newer competencies and the ever-growing complexity of healthcare, many post-graduate medical education systems across the globe have turned to outcomes-based models of education, codified through competency frameworks. This commentary provides a brief overview on key methods of work-based assessment such as direct observation, multisource feedback, patient experience surveys and performance measures that are needed in a competency-based world that places a premium on educational and clinical outcomes. However, the full potential of work-based assessments will only be realized if post-graduate learners play an active role in their own assessment program. This will require a substantial culture change, and culture change only occurs through actions and changed behaviors. Co-production offers a practical and philosophical approach to engaging postgraduate learners to be active, intrinsically motivated agents for their own professional development, help to change learning culture and contribute to improving

    The worldwide need for rapid expansion and diversification of medical devices and the corresponding requirements in industry pose arduous challenges for educators to train undergraduate biomedical engineering (BME) students. Preparing BME students for working in the research and development (R&D) in medical device industry is not easily accomplished by adopting traditional pedagogical methods. Even with the inclusion of the design and development elements in capstone projects, medical device industry may be still experience a gap in fulfilling their needs in R&D. This paper proposes a new model based on interdisciplinary project-based learning (IDPBL) to address the requirements of building the necessary skill sets in academia for carrying out R&D in medical device industry. The proposed model incorporates IDPBL modules distributed in a stepwise fashion through the four years of a typical BME program. The proposed model involves buy-in and collaboration from faculty as well as students. The implementation of the proposed design in an undergraduate BME program is still in process. However, a variant of the proposed IDPBL method has been attempted at a limited scale at the postgraduate level and has shown some success. Extrapolating the previous results, the adoption of the IDPBL to BME training seems to suggest promising outcomes. Despite numerous implementation challenges, with continued efforts, the proposed IDPBL will be valuable n academia for skill sets building for medical device R&D.

    Compact neutron generators can provide high flux of neutrons with energies ranging from thermal (0.025 eV) to 14 MeV. Recent measurements demonstrated high neutron yields from the D- 7 Li fusion reaction at an interaction energy of 500 keV. Using the D- 7 Li reaction and applying new advancements in high flux neutron generator technology along with the commercial availability of high voltage DC power supplies enables the production of useful quantities of radioisotopes for medical applications. Using the known neutron reaction cross-sections, it has been estimated that hundreds-to-thousands MBq (or tens-to-hundreds mCi) of 99 Mo, 225 Ac, 64 Cu and 67 Cu can be obtained from a compact high flux neutron generator.

Radiation dose of 50 kGy was selected for initial degradation of chitosan powder and followed by 12 kGy irradiation of 3CL2. A viscosity average molecular weight of ~10,000 of oligochitosan was obtained and subsequently used in the field trial of MR219 type of rice seeds on 24 hectares of rice plots. The seedlings were carried out after the rice seeds were soaked 24hrs in water and 30 minutes in 200ppm oligochitosan. The rice plots that were sprayed with oligochitosan were found to have higher resistant towards blast diseases. Oligochitosan of 40ppm was found to be effective as fungicides and resulted in the increase of yield of rice seeds of about 5%. (author)
