    The ADAMS Executive and Operating System, a multitasking environment under which a variety of data reduction, display and utility programs are executed, a system which provides a high level of isolation between programs allowing them to be developed and modified independently, is described. The Airborne Data Analysis/Monitor System (ADAMS) was developed to provide a real time data monitoring and analysis capability onboard Boeing commercial airplanes during flight testing. It inputs sensor data from an airplane performance data by applying transforms to the collected sensor data, and presents this data to test personnel via various display media. Current utilization and future development are addressed.

    Prescription medication overdose is the fastest growing drug-related problem in the USA. The growing nature of this problem necessitates the implementation of improved monitoring strategies for investigating the prevalence and patterns of abuse of specific medications. Our primary aims were to assess the possibility of utilizing social media as a resource for automatic monitoring of prescription medication abuse and to devise an automatic classification technique that can identify potentially abuse-indicating user posts. We collected Twitter user posts (tweets) associated with three commonly abused medications (Adderall(®), oxycodone, and quetiapine). We manually annotated 6400 tweets mentioning these three medications and a control medication (metformin) that is not the subject of abuse due to its mechanism of action. We performed quantitative and qualitative analyses of the annotated data to determine whether posts on Twitter contain signals of prescription medication abuse. Finally, we designed an automatic supervised classification technique to distinguish posts containing signals of medication abuse from those that do not and assessed the utility of Twitter in investigating patterns of abuse over time. Our analyses show that clear signals of medication abuse can be drawn from Twitter posts and the percentage of tweets containing abuse signals are significantly higher for the three case medications (Adderall(®): 23 %, quetiapine: 5.0 %, oxycodone: 12 %) than the proportion for the control medication (metformin: 0.3 %). Our automatic classification approach achieves 82 % accuracy overall (medication abuse class recall: 0.51, precision: 0.41, F measure: 0.46). To illustrate the utility of automatic classification, we show how the classification data can be used to analyze abuse patterns over time. Our study indicates that social media can be a crucial resource for obtaining abuse-related information for medications, and that automatic approaches involving

    Ansel Adams (1902-1984), photographer, musician, naturalist, explorer, critic, and teacher, was a giant in the field of landscape photography. In his images of the unspoiled Western landscape, he strove to capture the sublime: the transcendentalist concept that nature can generate the experience of awe for the viewer. Many viewers are familiar with the heroic, high-contrast prints on high-gloss paper that Adams made to order beginning in the 1970s; much less well known are the intimate prints that the artist crafted earlier in his career. This exhibition focuses on these masterful small prints from the 1920s into the 1950s. During this time period, Adams's printing style changed dramatically. The painterly, soft-focus, warm-toned style of the Parmelian Prints of the High Sierras from the 1920s evolved into the sharp-focus style of the f/64 school of photography that Adams co-founded in the 1930s with Edward Weston and Imogen Cunningham. After World War II, Adams opted for a cooler, higher-contrast look for his prints. Throughout the various styles in which he chose to work, Adams explored the power of nature and succeeded in establishing landscape photography as a legitimate form of modern art.

    The ADAMs are a family of multidomain transmembrane and secreted proteins involved in both proteolysis and cell adhesion. Altered expression of specific ADAMs is implicated in the pathophysiology of several diseases including rheumatoid arthritis, Alzheimer\\'s disease, cardiac hypertrophy, asthma and cancer. Of these different diseases, it is in cancer where most research has been carried out. Multiple ADAMs, including ADAM-9, ADAM-10, ADAM-12, ADAM-15 and ADAM-17, have been shown to play a role in either cancer formation or progression. Consistent with these findings, increased expression of specific ADAMs in several cancer types was found to correlate with features of aggressive disease and poor prognosis. Currently, selective ADAM inhibitors against ADAM-10 and ADAM-17 are undergoing clinical trials for the treatment of cancer. Further work is required in order to establish a causative role for ADAMs in rheumatoid arthritis, Alzheimer\\'s disease, cardiac hypertrophy and asthma.

    Childhood maltreatment is associated with error hypersensitivity. We examined the effect of childhood abuse and abuse-by-gene (5-HTTLPR, MAOA) interaction on functional brain connectivity during error processing in medication/drug-free adolescents. Functional connectivity was compared, using generalized psychophysiological interaction (gPPI) analysis of functional magnetic resonance imaging (fMRI) data, between 22 age- and gender-matched medication-naïve and substance abuse-free adolescents exposed to severe childhood abuse and 27 healthy controls, while they performed an individually adjusted tracking stop-signal task, designed to elicit 50% inhibition failures. During inhibition failures, abused participants relative to healthy controls exhibited reduced connectivity between right and left putamen, bilateral caudate and anterior cingulate cortex (ACC), and between right supplementary motor area (SMA) and right inferior and dorsolateral prefrontal cortex. Abuse-related connectivity abnormalities were associated with longer abuse duration. No group differences in connectivity were observed for successful inhibition. The findings suggest that childhood abuse is associated with decreased functional connectivity in fronto-cingulo-striatal networks during error processing. Furthermore that the severity of connectivity abnormalities increases with abuse duration. Reduced connectivity of error detection networks in maltreated individuals may be linked to constant monitoring of errors in order to avoid mistakes which, in abusive contexts, are often associated with harsh punishment.

    Background Cocaine use seems to be increasing in some urban areas worldwide, but it is not straightforward to determine the real extent of this phenomenon. Trends in drug abuse are currently estimated indirectly, mainly by large-scale social, medical, and crime statistics that may be biased or too generic. We thus tested a more direct approach based on 'field' evidence of cocaine use by the general population. Methods Cocaine and its main urinary metabolite (benzoylecgonine, BE) were measured by mass spectrometry in water samples collected from the River Po and urban waste water treatment plants of medium-size Italian cities. Drug concentration, water flow rate, and population at each site were used to estimate local cocaine consumption. Results We showed that cocaine and BE are present, and measurable, in surface waters of populated areas. The largest Italian river, the Po, with a five-million people catchment basin, steadily carried the equivalent of about 4 kg cocaine per day. This would imply an average daily use of at least 27 ± 5 doses (100 mg each) for every 1000 young adults, an estimate that greatly exceeds official national figures. Data from waste water treatment plants serving medium-size Italian cities were consistent with this figure. Conclusion This paper shows for the first time that an illicit drug, cocaine, is present in the aquatic environment, namely untreated urban waste water and a major river. We used environmental cocaine levels for estimating collective consumption of the drug, an approach with the unique potential ability to monitor local drug abuse trends in real time, while preserving the anonymity of individuals. The method tested here – in principle extendable to other drugs of abuse – might be further refined to become a standardized, objective tool for monitoring drug abuse. PMID:16083497

  19. Adam Smith and dependency.

    Science.gov (United States)

    Ozler, Sule

    2012-06-01

    The focus of this paper is the works and life of Adam Smith, who is widely recognized as the father and founder of contemporary economics. Latent content analysis is applied to his seminal text in economics, An Inquiry into the Nature and Causes of the Wealth of Nations (1776). The results reveal that Smith considers dependence on others a problem and sees the solution to this problem in impersonalized interdependence. In addition, his views on social dependency and personal dependency, reflected in his Lectures on Jurisprudence (1963) and The Theory of Moral Sentiments (1759), are analyzed. This analysis suggests a central tension between dependence and independence in Smith's writings. The personal dependency patterns he exhibited in his life, which also suggest a tension between dependence and independence, are identified through a reading of his biographies. Based on insights from psychoanalytic literature, this paper proposes that developing the ideas in the Wealth of Nations was part of Smith's creative solution to this tension. In particular, his solution to one individual's dependence on another was through a system of impersonalized interdependence. In other words, Smith defended against his personal dependence through his economic theorizing.

    A comparison was made of the relative sensitivities of electron impact and chemical ionization when used for selected ion monitoring analysis of commonly abused drugs. For most of the drugs examined chemical ionization using ammonia as the reactant gas gave the largest single m/e ion current response per unit weight of sample. However, if maximum sensitivity is desired it is important to evaluate electron impact and chemical ionization with respect to both maximum response and degree of interference from background and endogenous materials

    Butalbital, a barbiturate, is present in analgesic combinations used by headache sufferers. Overuse/abuse of these combinations may cause dependence, chronic migraine, and medication-overuse headache (MOH). MOH is difficult to manage: it improves interrupting analgesic overuse, but requires monitoring, because relapses are frequent. A gas chromatography-mass spectrometry (GC-MS) method for hair analysis has been developed and validated to document abuse of an analgesic combination containing butalbital and propyphenazone by a patient with MOH. For over ten years the patient managed her headache using eight suppositories/day of an analgesic combination containing butalbital 150mg, caffeine 75mg, and propyphenazone 375mg per suppository. An outpatient detoxification treatment was carried out. After three weeks, the patient reduced the consumption to one suppository/day. At the first control visit, after three months from the beginning of detoxification, the patient increased the use of the combination to four suppositories/day and at the second control visit, after seven months from the beginning of detoxification, she was back to eight suppositories/day. At the two control visits, a hair sample was taken for determination of butalbital and propyphenazone. Moreover blood and urine samples for determination of butalbital were drawn at the beginning of detoxification treatment and at the two control visits. With the segmental analysis of two hair samples the medication history of ten months could be estimated. In the first hair sample, collected at the first control visit, in the distal segment, butalbital and propyphenazone concentrations were, respectively, 17.5ng/mg and 56.0ng/mg, confirming the prolonged abuse; in the proximal segment, concurrently with the detoxification treatment, butalbital and propyphenazone concentrations had reduced respectively to 5.45ng/mg and 11.1ng/mg. The second hair sample, collected at the second control visit, proved the fair course

    Adam Heller, Ernest Cockrell Sr. Chair in Engineering Emeritus of the John J. McKetta Department of Chemical Engineering at The University of Texas at Austin, recalls his childhood in the Holocaust and his contributions to science and technology that earned him the US National Medal of Technology and Innovation in a conversation with Elton J. Cairns, Professor of Chemical and Biomolecular Engineering at the University of California, Berkeley. Dr. Heller, born in 1933, describes the enslavement of his father by Hungarians in 1942; the confiscation of his family's home, business, and all its belongings in 1944; and his incarceration in a brick factory with 18,000 Jews who were shipped by the Hungarians to be gassed by Germans in Auschwitz. Dr. Heller and his immediate family survived the Holocaust and arrived in Israel in 1945. He studied under Ernst David Bergmann at the Hebrew University, and then worked at Bell Laboratories and GTE Laboratories, where he headed Bell Lab's Electronic Materials Research Department. At GTE Laboratories, he built in 1966 the first neodymium liquid lasers and in 1973 with Jim Auborn conceived and engineered the lithium thionyl chloride battery, one of the first to be manufactured lithium batteries, which is still in use. After joining the faculty of engineering of The University of Texas at Austin, he cofounded with his son Ephraim Heller TheraSense, now a major part of Abbott Diabetes Care, which produced a microcoulometer that made the monitoring of glucose painless by accurately measuring the blood glucose concentration in 300 nL of blood. He also describes the electrical wiring of enzymes, the basis for Abbott's state-of-the-art continuous glucose monitoring system. He discusses his perspective of reducing the risk of catastrophic global warming in a wealth-accumulating, more-energy-consuming world and provides advice for students entering careers in science or engineering.

    Full text: When John Bertram Adams died on 3 March 1984, CERN lost one of its principal architects. The late Sir John Adams was a very private person who rarely confided in his colleagues. This made the job of his biographer particularly difficult. Michael Crowley- Milling has succeeded admirably, and has performed a very important service. Is it a potted history of CERN, or the story of the building of the PS, or of the SPS? Yes, all of these, but most of all it is a thoughtful and discerning biography and a fitting tribute to a veritable giant of European science and technology. The sub-title,' Engineer Extraordinary' refers not only to John's outstanding ability as a builder of accelerators, but perhaps even more importantly, as a builder of teams and an 'engineer of opinions'. The book describes how John's attention to detail and intuitive engineering skills developed during the early part of his career, when working in radar research, and how he emerged as a natural leader in the building of the CERN PS. Then later, how his statesmanship enabled him to ''...rescue it (the 300 GeV Programme) from seeming political disaster and nurse it through technical problems to a successful conclusion.'' One crucial part of this process described is the visit to CERN in 1970 by Margaret Thatcher, at that time UK Secretary of State for Education and Science, and her subsequent letters of thanks, not only to Bernard Gregory as Director General, but also to John. It is interesting to speculate to what extent the good impression made on that occasion helped many years later, when as Prime Minister Mrs Thatcher decided that Britain should stay in CERN! After the successful commissioning of the SPS, the book goes on to describe the period when the two CERN Laboratories were merged under two Directors General. Unfortunately I found this part a little too low key, given that John and Leon van Hove presided over what was undoubtedly

    In this first John Adams' Memorial Lecture, an outline is given of his work, especially from the beginning of CERN in 1952 until his death in 1984. The historical survey covers John Adams' technical and managerial contributions to the development of CERN and its accelerators, as well as to fusion research in Britain and Europe. Exemplified by his role as member and president of the International Committee for Future Accelerators (ICFA), Adams' interest in international co-operation is also stressed. In the spirit of this great European, arguments are given for CERN to continue to be the first-rate high-energy physics laboratory which it has been in the past. (orig.)

    The Arkansas Prescription Monitoring Program (AR PMP) was implemented in 2013 to combat prescription drug abuse. All enrollees were invited to participate in a user survey available in February 2014, to identify makeup of users, utilization of the program, and changes made to health care practices after implementation of the program. Of the 3,694 individual enrollees invited to participate, 1,541(41.7%) completed the survey. Data collected were analyzed to identify changes in health care practices by program frequency of use and user profession. Medical doctors, advanced practice nurses, and pharmacists are the professions who use the program most frequently. Daily AR PMP users are considerably more likely than infrequent users to be prompted to access the program by the involvement of a controlled substance (CS) prescription or by office/facility policy requirements. Increased frequency of use of the AR PMP results in positive impacts on CS prescribing and dispensing practices. Compelling more users of the AR PMP to be prompted to access the program by the involvement of a CS prescription or by requirements per office/facility policy may increase frequency of use of the program and thereby changes in health care practices to combat prescription drug abuse.

    To facilitate the monitoring of drug abuse by patients, a method was developed and validated for the analysis of amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine, methylenedioxyamphetamine, methylenedioxyethylamphetamine, methylphenidate, cocaine, benzoylecgonine, morphine, codeine, heroin, 6-monoacteylmorphine, methadone, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), delta-9-tetrahydrocannabinol (THC), nicotine, and cotinine in human hair. The hair preparation method contains a 3-step wash procedure with dichloromethane followed by a simultaneous hair pulverization and extraction procedure with disposable metal balls. The developed liquid chromatography tandem mass spectrometry method uses a single injection to detect and confirm all 17 abused drugs, including THC, within 4.8 minutes. Nicotine was validated with a linear range of 800-25,000 pg/mg hair, and all other substances were validated with a linear range of 30.0-2500 pg/mg hair. For inaccuracy and imprecision, the overall bias did not exceed -8.2% and the overall coefficient of variation did not exceed 17.7%. Autosampler stability was proven for 48 hours at 10°C for all substances. Analytical cutoff concentrations were defined for each substance at the lowest validated inaccuracy and imprecision concentration with a bias and coefficient of variation within 15% and qualifier/quantifier ratios within 20% of the set ratio. The analytical cutoff concentrations were 200 pg/mg for codeine and 80.0 pg/mg for 6-MAM, heroin, EDDP, and THC. The analytical cutoff concentration for nicotine was 800 pg/mg and for all other validated substances 30.0 pg/mg. This method was successfully applied to analyze hair samples from patients who were monitored for drug abuse. Hair samples of 47 subjects (segmented into 129 samples) showed 3,4-methylenedioxymethamphetamine, methylphenidate, cocaine, benzoylecgonine, codeine, methadone, EDDP, THC, nicotine, and cotinine above the analytical cutoff.

    To demonstrate the value of poison control data as an adjunct to national drug abuse surveys and a source of data to inform and focus prevention efforts. National Poison Data System (NPDS) data are collected and compiled in real time by the 60 US poison centers as callers seek guidance for poison exposures. Demographic, geographic, product, outcome, and treatment-site data for the 35453 inhalant cases reported between 1993 and 2008 were analyzed. The prevalence of inhalant cases reported to US poison control centers decreased 33% from 1993 to 2008. Prevalence was highest among children aged 12 to 17 years and peaked in 14-year-olds. In contrast to national survey data showing nearly equal use of inhalants by both genders, 73.5% of NPDS inhalant cases occurred in boys, which suggests that boys may pursue riskier usage behaviors. Most cases (67.8%) were managed in health care facilities. More than 3400 different products were reported. Propellants, gasoline, and paint were the most frequent product categories. Propellants were the only product category that substantially increased over time. Butane, propane, and air fresheners had the highest fatality rates. Prevalence for all inhalants was highest in western mountain states and West Virginia, but geographic distribution varied according to product type. Gasoline was a proportionately greater problem for younger children; propellants were an issue for older children. NPDS should be used to monitor inhalant abuse because it provides unique, timely, and clinically useful information on medical outcomes experienced by users, includes detailed product information (brand and formulation), and can potentially be used to identify real-time demographic, geographic, and product trends. Focusing inhalant prevention efforts on the most hazardous products and most seriously affected users may improve and facilitate strategic prevention, enabling interventions such as targeted education, product reformulation, repackaging

    The 'Hague Protocol' enables professionals at the adult Emergency Department (ED) to detect child abuse based on three parental characteristics: (i) suicide attempt or self-harm, (ii) domestic violence or (iii) substance abuse, and to refer them to the Reporting Centre for Child Abuse and Neglect (RCCAN). This study investigates what had happened to the families three months after this referral. ED referrals based on parental characteristics (N = 100) in which child abuse was confirmed after investigation by the RCCAN were analysed. Information was collected regarding type of child abuse, reason for reporting, duration of problems prior to the ED referral, previous involvement of support services or other agencies, re-occurrence of the problems and outcome of the RCCAN monitoring according to professionals and the families. Of the 100 referred cases, 68 families were already known to the RCCAN, the police or family support services, prior to the ED referral. Of the 99 cases where information was available, existing support was continued or intensified in 31, a Child Protection Services (CPS) report had to be made in 24, new support was organized for 27 cases and in 17 cases support was not necessary, because the domestic problems were already resolved. Even though the RCCAN is mandated to monitor all referred families after three months, 31 cases which were referred internally were not followed up. Before referral by the ED two thirds of these families were already known to organizations. Monitoring may help provide a better, more sustained service and prevent and resolve domestic problems. A national database could help to link data and to streamline care for victims and families. We recommend a Randomized Controlled Trial to test the effectiveness of this Protocol in combination with the outcomes of the provided family support. © 2014 John Wiley & Sons Ltd.

    Full Text Available Hair testing is a useful tool to investigate the prevalence of unsuspected chronic exposure to drugs of abuse in pediatric populations and it has been applied to three different cohorts of children from Barcelona, Spain along fifteen years to evaluate eventual changes in this exposure. Children were recruited from three independent studies performed at Hospital del Mar (Barcelona, Spain and approved by the local Ethics Committee. Hair samples were collected from the first 187 children cohort (around 4 years of age in 1998, from the second 90 children cohort (1.5–5 years of age in 2008 and from the third 114 children cohort (5–14 years of age in 2013. Hair samples were analysed for the presence of opiates, cocaine, amphetamines, and cannabis by validated methodologies using gas or liquid chromatography-mass spectrometry. Familiar sociodemographics and eventual consumption of drugs of abuse by parents, and caregivers were recorded. Hair samples from 24.6% children in 1998 were positive for any drug of abuse (23.0% cocaine, 25.5% in 2008 (23.3% cocaine, and 28.1% in 2013 (20.1% cocaine and 11.4% cannabis. In none of the cohorts, parental sociodemographics were associated with children exposure to drugs of abuse. The results of the three study cohorts demonstrated a significant prevalence of unsuspected pediatric exposure to drugs of abuse which mainly involved cocaine maintained along fifteen years in Barcelona, Spain. We recommend to be aware about unsuspected passive exposure to drugs of abuse in general population and to use general or selected hair screening to disclose exposure to drugs of abuse in children from risky environments to provide the basis for specific social and health interventions.

    2013-08-01

    Written against the backdrop of criticism levelled at paragraph 29 of the Law Against Restraints on Competition (GWB) the present study undertakes a critical discussion of this legal norm along with questions and points of criticism that have been raised in its context in the literature and case law. It first addresses the central question as to whether paragraph 29 GWB conforms to the stipulations of European law and the German constitution. It then expounds the system behind paragraph 29 GWB, making a detailed examination of the individual elements of the offences covered by the regulation while giving thorough consideration to existing case law on instruments of price abuse monitoring that have been used to date under cartel law. A further focus of the present study is on the question as to what circumstances a supply company under suspicion of price abuse may claim in attempting to justify significant differences that have been found to exist between its own prices and those of a comparable company. This aspect is of great practical relevance in lawsuits concerning price abuse under cartel law, since the option of demonstrating justification is the most important line of approach for supply companies under suspicion of price abuse in attempting to fend off such allegations. Based on an analysis of past practice of the German Federal Cartel Office and the antitrust courts the author undertakes to determine a scale for assessing the costs which the responding supply company can claim in its defence. Finally she endeavours to methodologically capture the price limit concept, making proposals for its practical application with due consideration to the findings that have transpired from the study.

    Full Text Available Increasing numbers of reports about the role of adamalysins (ADAM in malignant tumors are being published. To date, more than 30 representatives of this group, out of which about 20 occur in humans, have been described. The ADAM family is a homogeneous group of proteins which regulate, from the stage of embryogenesis, a series of processes such as cell migration, adhesion, and cell fusion. Half of them have proteolytic activity and are involved in the degradation of the extracellular matrix and the disintegration of certain protein complexes, thereby regulating the bioavailability of various growth factors. Many of these functions have a direct role in the processes of carcinogenesis and promoting the growth of tumor, which affect some signaling pathways, including those related to insulin-like growth factors (IGF1, IGF2, vascular growth factor (VEGF, tumor necrosis factor α (TNFα and the EGFR/HER pathway. Another branch of studies is the evaluation of the possibility of using members of ADAM family proteins in the diagnosis, especially in breast, colon and non- small cell lung cancer. The detection of concentrations of adamalysin in serum, urine and pleural aspirates might contribute to the development of methods of early diagnosis of cancer and monitoring the therapy. However, both the role of adamalysins in the development and progression of tumors and their importance as a diagnostic and predictive further research still need to be checked on large groups of patients.

  1. Simulation of Failure in Gearbox Using MSC.Adams

    2017-01-01

    Full Text Available Vehicle’s gearbox is regarded as one of the most crucial elements in a vehicle but it sustains a variety of faults such as a broken tooth, misalignment, imbalance, looseness, and even a broken case. Using accelerometers, which are mounted on the case to measure a vibration signal, we can detect faults and monitor the condition but the signals are often complicated and difficult to interpret. Moreover, it is costly and almost impossible to change the structure of a gearbox in order to survey, for instance, the dependence of a vibration signal on the structure, or types of a fault. In this paper a dynamic model of gearbox was developed with tooth breakage to study the capability of simulation using MSC.Adams software. In this simulation we focus on the gearbox used in a common military vehicle. The simulation was based on a nonlinear contact force to predict what happens to the gearbox in case the tooth breaks. The contact mechanics model of the meshing teeth is studied thoroughly by selecting contact simulation parameters such as stiffness, force exponent, damping and friction coefficients. To simulate the real working environment of the gearbox, simulated bearings were also built in the MSC.Adams. The paper shows that it is possible to simulate vibration signals by the gearbox model created in 3D CAD software and analyze the results in the multi‑body dynamics software MSC.Adams.

  2. John Quincy Adams's rhetorical crusade for astronomy.

    2000-09-01

    Astronomy thrived in Europe during the early nineteenth century, but in the United States a utilitarian mind-set opposed it. John Quincy Adams's oratory in support of American astronomical discovery reached its peak during congressional debate over the Smithsonian Institution (1838-1846). During this debate Adams countered proposals to found a university with plans for an observatory. His addresses to congressional and public audiences about observatories and astronomy were intended to foster interest in the science and encourage the growing astronomical community in America. Although the U.S. Naval Observatory in Washington, D.C., was established before the Smithsonian debate ended, many considered Adams its political father. Adams composed his speeches on astronomy in a systematic manner, following neoclassical principles of rhetoric that he had taught at Harvard University. His speeches both in and outside of Congress show evidence of the rhetorical principles he conscientiously used in the service of astronomy.

    Full Text Available Abstract Background In a transgenic mouse model of Alzheimer disease (AD, cleavage of the amyloid precursor protein (APP by the α-secretase ADAM10 prevented amyloid plaque formation, and alleviated cognitive deficits. Furthermore, ADAM10 overexpression increased the cortical synaptogenesis. These results suggest that upregulation of ADAM10 in the brain has beneficial effects on AD pathology. Results To assess the influence of ADAM10 on the gene expression profile in the brain, we performed a microarray analysis using RNA isolated from brains of five months old mice overexpressing either the α-secretase ADAM10, or a dominant-negative mutant (dn of this enzyme. As compared to non-transgenic wild-type mice, in ADAM10 transgenic mice 355 genes, and in dnADAM10 mice 143 genes were found to be differentially expressed. A higher number of genes was differentially regulated in double-transgenic mouse strains additionally expressing the human APP[V717I] mutant. Overexpression of proteolytically active ADAM10 affected several physiological pathways, such as cell communication, nervous system development, neuron projection as well as synaptic transmission. Although ADAM10 has been implicated in Notch and β-catenin signaling, no significant changes in the respective target genes were observed in adult ADAM10 transgenic mice. Real-time RT-PCR confirmed a downregulation of genes coding for the inflammation-associated proteins S100a8 and S100a9 induced by moderate ADAM10 overexpression. Overexpression of the dominant-negative form dnADAM10 led to a significant increase in the expression of the fatty acid-binding protein Fabp7, which also has been found in higher amounts in brains of Down syndrome patients. Conclusion In general, there was only a moderate alteration of gene expression in ADAM10 overexpressing mice. Genes coding for pro-inflammatory or pro-apoptotic proteins were not over-represented among differentially regulated genes. Even a decrease of

    Serotonin transporters (SERT) are target-sites for commonly used antidepressants, such as fluoxetine, paroxetine, sertraline, and so on. Imaging of these sites in the living human brain may provide an important tool to evaluate the mechanisms of action as well as to monitor the treatment of depressed patients. Synthesis and characterization of an improved SERT imaging agent, ADAM (2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine)(7) was achieved. The new compound, ADAM(7), displayed an extremely potent binding affinity toward SERT (K{sub i}=0.013 nM, in membrane preparations of LLC-PK{sub 1}-cloned cell lines expressing the specific monoamine transporter). ADAM(7) also showed more than 1,000-fold selectivity for SERT over norepinephrine transporter (NET) and dopamine transporter (DAT) (K{sub i}=699 and 840 nM, for NET and DAT, respectively). The radiolabeled compound [{sup 125}I]ADAM(7) showed an excellent brain uptake in rats (1.41% dose at 2 min post intravenous [IV] injection), and consistently displayed the highest uptake (between 60-240 min post IV injection) in hypothalamus, a region with the highest density of SERT. The specific uptake of [{sup 125}I]ADAM(7) in the hypothalamus exhibited the highest target-to-nontarget ratio ([hypothalamus - cerebellum]/cerebellum was 3.97 at 120 min post IV injection). The preliminary imaging study of [{sup 123}I]ADAM in the brain of a baboon by single photon emission computed tomography (SPECT) at 180-240 min post IV injection indicated a specific uptake in midbrain region rich in SERT. These data suggest that the new ligand [{sup 123}I]ADAM(7) may be useful for SPECT imaging of SERT binding sites in the human brain.

    Full Text Available Abstract Background The low-density lipoprotein receptor-related protein 1 (LRP1 plays critical roles in lipid metabolism, cell survival, and the clearance of amyloid-β (Aβ peptide. Functional soluble LRP1 (sLRP1 has been detected in circulating human placenta; however, whether sLRP1 is also present in the central nervous system is unclear. Results Here we show that abundant sLRP1 capable of binding its ligands is present in human brain tissue and cerebral spinal fluid (CSF. Interestingly, the levels of sLRP1 in CSF are significantly increased in older individuals, suggesting that either LRP1 shedding is increased or sLRP1 clearance is decreased during aging. To examine potential effects of pathological ligands on LRP1 shedding, we treated MEF cells with Aβ peptide and found that LRP1 shedding was increased. ADAM10 and ADAM17 are key members of the ADAM family that process membrane-associated proteins including amyloid precursor protein and Notch. We found that LRP1 shedding was significantly decreased in MEF cells lacking ADAM10 and/or ADAM17. Furthermore, forced expression of ADAM10 increased LRP1 shedding, which was inhibited by ADAM-specific inhibitor TIMP-3. Conclusion Our results demonstrate that LRP1 is shed by ADAM10 and ADAM17 and functional sLRP1 is abundantly present in human brain and CSF. Dysregulated LRP1 shedding during aging could alter its function and may contribute to the pathogenesis of AD.

    2016-01-01

    We aimed to evaluate whether living tissues such as urine, plasma and hair were suitable for monitoring clenbuterol (CL) abuse after its subchronic administration of a growth-promoting dose to the Chinese Simmental beef cattle. Eight male, white and red pied Chinese Simmental beef cattle were involved in the experiment, and the CL dose was 16 µg/kg BW/day. Liquid chromatography tandem mass spectrometry (LC-MS-MS) was used to determine CL residues in different tissues, and the addition of D9-clenbuterol internal standard was applied to increase determination accuracy. The recovery of plasma, urine, hair and in vivo tissues was 88.5-114.2, 83.9-114.3, 88.6-116.9 and 85.3-121.7%, respectively. The results showed that CL residue concentrations in the plasma, on Days 14 after withdrawal and later, were lower than the limit of detection (LOD) (0.06 ng/mL) and CL residue in urine was lower than LOD (0.16 ng/mL) 42 days after treatment. CL significantly accumulated in the white and red hair and maintained more than 7.19 ± 2.19 pg/mg within the early withdrawal period of 70 days. A large number of CL were determined in all tested biological tissues, in which residues were higher than the maximum residue limits (MRLs) after dietary administration of CL for 21 days and pre-slaughter withdrawal period of ∼6 h. A particular concern is the slow depletion of residues of CL in some tissues like gluteus and liver still exceeding theirs MRLs, respectively, on Days 14 or 28 days after withdrawal. Our study indicated that plasma and urine could be available for monitoring CL abuse only within a short period of time. However, hair (including light-pigmented) as a target matrix can be selected to perform the long-period monitor of CL. © The Author 2015. Published by Oxford University Press. All rights reserved.

  19. Role of ADAMs in cancer formation and progression.

    LENUS (Irish Health Repository)

    Duffy, Michael J

    2012-02-01

    The ADAMs (a disintegrin and metalloproteinase) comprise a family of multidomain transmembrane and secreted proteins. One of their best-established roles is the release of biologically important ligands, such as tumor necrosis factor-alpha, epidermal growth factor, transforming growth factor-alpha, and amphiregulin. Because these ligands have been implicated in the formation and progression of tumors, it might be expected that the specific ADAMs involved in their release would also be involved in malignancy. Consistent with this hypothesis, emerging data from model systems suggest that ADAMs, such as ADAM-9, ADAM-12, ADAM-15, and ADAM-17, are causally involved in tumor formation\\/progression. In human cancer, specific ADAMs are up-regulated, with levels generally correlating with parameters of tumor progression and poor outcome. In preclinical models, selective ADAM inhibitors against ADAM-10 and ADAM-17 have been shown to synergize with existing therapies in decreasing tumor growth. The ADAMs are thus a new family of potential targets for the treatment of cancer, especially malignancies that are dependent on human epidermal growth factor receptor ligands or tumor necrosis factor-alpha.

    2013-01-01

    Full Text Available The routine collection of drug treatment outcomes to manage quality of care, improve patient satisfaction, and allocate treatment resources is currently hampered by two key difficulties: (1 problems locating clients once they leave treatment; and (2 the prohibitive cost of obtaining meaningful and reliable post-treatment data. This pilot describes precise methods for an economical staff-based routine outcome monitoring (ROM system using an 18-item core measure telephone survey. As implemented at Narconon TM of Oklahoma, a behavioral and social skills based, residential drug rehabilitation program, the system was psychometrically adequate for aggregate reporting while providing clinically useful information. Standardized procedures for staff training, collecting client contact information, structuring exit interviews and maintaining post-treatment telephone contact produced follow-up rates that improved from 57.6% to 100% over the course of the project. Aggregate data was used to improve program delivery and thereby post-treatment substance use and social outcomes. These methods and use of data may contribute to the discussion on how to best monitor outcomes.

    Rudolph, Julia; Zimmer-Gembeck, Melanie J; Shanley, Dianne C; Walsh, Kerrryann; Hawkins, Russell

    2018-03-01

    We investigated whether parents who reported more positive parenting practices (i.e., monitoring, involvement, and communication) reported more discussion of child sexual abuse (CSA) with their children. Parents from Australia and the UK (N = 248), with children aged 6 to 11 years, completed an online survey. About half of parents reported directly discussing CSA, whereas 35% reported telling their children that CSA perpetrators may be family members. Rates of discussion were higher for other CSA-related topics such as body integrity and abduction. Correlational analyses showed that parents who reported speaking to their children about CSA also reported more positive parenting practices, more discussion of other sensitive topics, and assessed CSA risk for children (in general) to be higher. Discussion of CSA risk was not associated with parents' CSA knowledge, confidence or appraisal of own-child risk. Parents higher in positive parenting believed their children to be at less CSA risk. Parents who appraised higher own-child risk reported less positive parenting practices and were less confident about their parenting and their ability to protect their children from CSA. The findings are the first to report on the associations of parenting practices with parents' CSA discussion with their children.

    This study reports the results of a pilot program in Kenosha County that used a combination of direct biomarkers extracted from blood spots and nails to monitor repeat intoxicated drivers for their use of alcohol and drugs with a detection window spanning from 3 weeks to several months. The objectives were to test whether the direct biomarkers phosphatidylethanol (PEth), ethylglucuronide (EtG), and 5 drug metabolites would (1) help assessors obtain a more objective evaluation of repeat offenders during the assessment interview, (2) allow for timely identification of relapses and improve classification of drivers into risk categories, and (3) predict recidivism by identifying offenders most likely to obtain a subsequent operating while intoxicated (OWI) offense within 4 years of enrollment in the program. All (N = 261) repeat offenders were tested using PEth obtained from blood spots and EtG obtained from fingernails; 159 participants were also tested for a 5 drugs of abuse nail panel. Drivers were tested immediately after the assessment interview (baseline) and at 3, 6, 9, and 12 months after baseline. Based on biomarker results and self-reports of abstinence, offenders were classified into different risk categories and required to follow specific testing timelines based on the program's decision tree. The baseline analysis shows that 60% of drivers tested positive for alcohol biomarkers (EtG, PEth, or both) at the assessment interview, with lower detection rates (0-11%) for the 5 drug metabolites. The comparison of biomarkers results to self-reports of abstinence identified 28% of all offenders as high risk and assigned them to more frequent testing and more intense monitoring. The longitudinal analysis shows that 56% (completers) of participants completed the program successfully and the remaining 44% (noncompliant) terminated prematurely. Two thirds (68%) of the completers were able to reduce or control their drinking and one third relapsed at least one time

  10. Internal architecture of the proximal femur--Adam's or Adams' arch? Historical mystery.

    Science.gov (United States)

    Bartonícek, J

    2002-12-01

    The designation 'Adam Bogen' describing the thick medial cortex of the femoral neck is an incorrect term. This arch was described by Robert Adams (1795-1871), an outstanding Irish anatomist and surgeon. He was famous mainly for his book on gout and the description of disorders of cardiac rhythm, the so-called Adams-Stokes syndrome. He published his original description in the today unfortunately almost forgotten Cyclopaedia of Anatomy and Physiology, Vol. II (London, Longman, 1836-1839). The main editor of this monumental six-volume work was the famous anatomist and surgeon R.B.Todd. This book represents a significant source of information on diseases and injuries of the great joints (shoulder, elbow, wrist, knee, ankle).

  11. Promoting consistent use of prescription drug monitoring programs (PDMP) in outpatient pharmacies: Removing administrative barriers and increasing awareness of Rx drug abuse.

    Norwood, Connor W; Wright, Eric R

    2016-01-01

    Prescription drug monitoring programs (PDMPs) are proving to be valuable resources in fighting the prescription drug abuse epidemic through improved access to patient drug histories. Ninety-four percent of Indiana pharmacists have heard of Indiana's PDMP (INSPECT), only 71% of them reported using the program in 2012. To identify barriers to PDMP use in outpatient pharmacies and determine the impact these barriers have on utilization. A cross-sectional study examined pharmacists' knowledge and use of INSPECT. Bivariate analyses on utilization and perceived barriers were conducted using cross-tabulations and chi-squared tests. Multiple logistic regression examined the relationship between pharmacists' level of concern with prescription drug abuse and reported utilization. Pharmacists were significantly less likely to use INSPECT if they reported at least one barrier and 3 times more likely to use INSPECT if they reported no barrier. Pharmacists were 10 times more likely to use INSPECT and 18 times more likely to use it more consistently if they were extremely concerned about prescription drug abuse in their community as compared to those not at all concerned. Strategies to improve utilization of PDMPs should look for innovative ways to limit barriers and build outpatient pharmacists' awareness of prescription drug abuse and misuse within their community.

    Space imagery offers remote surveillance of ethnic people groups at risk of human rights abuse. We highlight work in alleged violations in Burma and Sudan, using satellite imagery for verification with Amnesty International. We consider how imaging may effectively support small to medium-sized Non Governmental Organisations and charities, e.g. HART, working in dangerous zones on the ground. Satellite based sensing applications are now at a sufficiently mature stage for moderate Governmental funding levels to help prevent human rights abuse, rather than the greater cost of rebuilding communities and healing sectarian divisions after abuse has taken place.

    This study aimed to: (a) determine the percentage of ED patients receiving prescriptions for opioid pain medications that meet the criteria for "high-risk for abuse potential" on the Screener and Opioid Assessment for Patients with Pain (SOAPP(®)-R), (b) determine the percentage of patients with high-risk behavior on the state prescription drug monitoring program (PDMP) database, (c) compare the SOAPP-R with data from the PDMP, and (d) determine psychometric properties of SOAPP-R for ED patients Convenience sample of ED patients who were being considered for discharge with a prescription for an opioid pain medication. Subjects completed SOAPP-R on an electronic tablet and PDMP data was obtained. Scores on SOAPP-R ≥ 18 were defined as "at-risk", and PDMP data showing both ≥ 4 opioid prescriptions and ≥ 4 providers in 12 months was considered the criterion standard for high-risk behavior. 82 patients (88.2%) provided consent. 32.9% (n=27) were determined to be "at-risk" (score ≥ 18) by SOAPP-R. 15.9% (n=13) subjects met PDMP criteria and 53.9% (n=7) of those had SOAPP-R scores ≥ 18 (sensitivity 54%, specificity 71%, positive predictive value 26%, negative predictive value 89%). The association of an at-risk SOAPP-R score and PDMP high-risk criteria was an adjusted odds ratio of 1.39 (95% confidence interval 0.73-3.68). In our population, about one-third of patients being considered for discharge with an opioid prescription scored "at-risk" on SOAPP-R and 15.9% met the PDMP high-risk criteria. The high negative predictive value of SOAPP-R indicates it may be a useful screening tool for the ED patient population. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The ADAMs (a disintegrin and metalloprotease) are a family of multidomain proteins with structural homology to snake venom metalloproteases. We recently described the cloning and sequencing of human ADAM 12 (meltrin alpha). In this report we provide evidence that the metalloprotease domain of ADAM...... 12 is catalytically active. We used the trapping mechanism of alpha2-macroglobulin to assay for protease activity of wild-type and mutant ADAM 12 proteins produced in a COS cell transfection system. We found that ADAM 12 is synthesized as a zymogen, with the prodomain maintaining the metalloprotease...... in a latent form, probably by means of a cysteine switch. The zymogen could be activated chemically by alkylation with N-ethylmaleimide. Cleavage of the prodomain at a site for a furin-like endopeptidase resulted in an ADAM 12 protein with proteolytic activity. The protease activity was sensitive...

    1996-01-01

    Fifty years ago Frank Goward of the Atomic Energy Research Establishment Group at Malvern converted a small American betatron to make the worldÕs first synchrotron. At the same time Marcus Oliphant was planning to build at Birmingham a large proton machine with a ring magnet and variable magnetic field. Ideas for this had come to him during night-shifts tending the electromagnetic separators at Oak Ridge during the war. Some seven years later, in 1953, a group gathered together in Geneva to build the PS. A major contributor to the design work which had made this possible was John Adams. An account of some of the achievements in these eventful years will be presented. CERN has built nine synchrotrons/colliders and two temporary test rings. Eight machines are still running. The review will start with the PS, the first proton synchrotron based on the alternating gradient principle invented in 1952 at BNL. The design work of the PS team, under the enlightened leadership of J.B. Adams, and the construction of the...

    2009-01-01

    The analytical performance of the clinical chemistry module c 501 (cobas 6000 analyzer series) was evaluated for therapeutic drug monitoring and drugs of abuse testing using a spectrum of representative assays. Particular attention was paid to potential interactions between reagents using a simulated routine workload. Within-run and total imprecision were assessed using a selection of representative reagents. Deviation from a consensus mean was tested using samples from a proficiency testing scheme. Method comparison using routine samples was carried out against the MODULAR ANALYTICS SWA and COBAS INTEGRA 800 analysis systems. Total coefficients of variation (CV) ranged from 1.9% to 7.8% for individual drugs, and from 3.2% to 8.6% for drugs of abuse testing. Results from proficiency test samples were between 81% and 125% of the consensus mean for therapeutic drugs. Method comparisons (Passing-Bablok regression) showed overall good comparability to MODULAR ANALYTICS SWA and COBAS INTEGRA 800 systems, with slopes from 0.93 to 1.17 and correlation coefficients r > 0.98. Imprecision in a simulated routine run was tested using a total of 42 methods (10 therapeutic drug monitoring, 9 drugs of abuse testing, 3 enzymes, 12 substrates, 8 specific protein assays). Imprecision in the reference batch run ranged from 0.7% to 5.0% CV for therapeutic drug monitoring assays, except for digoxin (DIG) (7.3%), and from 0.9% to 7.7% for drugs of abuse testing. The CVs of general clinical chemistry and specific protein tests were within the expected limits of 2% and 4%. CV changes in the simulated routine run were within the expected limits for most assays. Negative DeltaCVs (> or = 2%) for DIG, digitoxin (DIGIT), cannabinoids (THC), and phencyclidine (PCP) may indicate improved performance when running these assays in a simulated routine operation. A positive DeltaCV (> or = 3%) was found for amphetamines (AMPHs). In conclusion, the cobas c 501 module seems to be well-suited for

    2013-01-01

    By any standards, John Adams had a most remarkable career. He was involved in three important, emerging technologies, radar, particle accelerators and controlled fusion, and had an outstanding impact on the last two. Without a university education, he attained hierarchical positions of the highest level in prestigious national and international organizations. This article covers the CERN part of his career, by offering some personal insights into the different facets of his contributions to major accelerator projects, from the first strong-focusing synchrotron, the PS, to the SPS and its conversion to a proton–antiproton collider. In particular, it outlines his abilities as a leader of an international collaboration, which has served as an example for international initiatives in other disciplines.

  8. Expression, immunolocalization and processing of fertilins ADAM-1 and ADAM-2 in the boar (sus domesticus) spermatozoa during epididymal maturation

    Science.gov (United States)

    2011-01-01

    Fertilin alpha (ADAM-1) and beta (ADAM-2) are integral membrane proteins of the ADAM family that form a fertilin complex involved in key steps of the sperm-oocyte membrane interaction. In the present work, we analyzed the presence of ADAM-1 and ADAM-2 mRNAs, the spermatozoa proteins' processing and their sub-cellular localization in epididymal samples from adult boars. ADAM-1 and ADAM-2 mRNAs were highly produced in the testis, but also in the vas efferens and the epididymis. On immunoblots of sperm extracts, ADAM-1 subunit appeared as a main reactive band of ~50-55 kDa corresponding to occurrence of different isoforms throughout the epididymal duct, especially in the corpus region where isoforms ranged from acidic to basic pI. In contrast, ADAM-2 was detected as several bands of ~90 kDa, ~75 kDa, ~50-55 kDa and ~40 kDa. The intensity of high molecular mass bands decreased progressively in the distal corpus where lower bands were also transiently observed, and only the ~40 kDa was observed in the cauda. The presence of bands of different molecular weights likely results from a proteolytic processing occurring mainly in the testis for ADAM-1, and also throughout the caput epididymis for ADAM-2. Immunolocalization showed that fertilin migrates from the acrosomal region to the acrosomal ridge during the sperm transit from the distal corpus to the proximal cauda. This migration is accompanied by an important change in the extractability of a part of ADAM-1 from the sperm membrane. This suggests that the fertilin surface migration may be triggered by the biochemical changes induced by the epididymal post-translational processing of both ADAM1 and ADAM-2. Different patterns of fertilin immunolocalization then define several populations of spermatozoa in the cauda epididymis. Characterization of such fertilin complex maturation patterns is an important step to develop fertility markers based on epididymal maturation of surface membrane proteins in domestic mammals. PMID

Maternal serum and whole blood pools were stored at 30 degrees C, room temperature and refrigerator temperature or subjected to repeated freeze-thaw cycles. ADAM-12 was measured at set time points using an automated DELFIA research assay. Using a 10% change in concentration as a limit of stability, ADAM-12 is stable in serum for less than 15 h at 30 degrees C, less than 20 h at room temperature and for 51 h at refrigerator temperature. ADAM-12 levels are not altered following three - 20 degrees C to room temperature freeze-thaw cycles. The stability of ADAM-12 in whole blood appears similar to that in serum. The findings of this study suggest that ADAM-12 may be unstable under many routine laboratory conditions, and the marker's instability may also be partly responsible for the discrepancies in the literature.

  11. The Metalloproteinase ADAM28 Promotes Metabolic Dysfunction in Mice

    Full Text Available Obesity and diabetes are major causes of morbidity and mortality globally. The current study builds upon our previous association studies highlighting that A Disintegrin And Metalloproteinase 28 (ADAM28 appears to be implicated in the pathogenesis of obesity and type 2 diabetes in humans. Our novel study characterised the expression of ADAM28 in mice with the metabolic syndrome and used molecular inhibition approaches to investigate the functional role of ADAM28 in the pathogenesis of high fat diet-induced obesity. We identified that ADAM28 mRNA and protein expression was markedly increased in the livers of mice with the metabolic syndrome. In addition, noradrenaline, the major neurotransmitter of the sympathetic nervous system, results in elevated Adam28 mRNA expression in human monocytes. Downregulation of ADAM28 with siRNA technology resulted in a lack of weight gain, promotion of insulin sensitivity/glucose tolerance and decreased liver tumour necrosis factor-α (TNF-α levels in our diet-induced obesity mouse model as well as reduced blood urea nitrogen, alkaline phosphatase and aspartate aminotransferase. In addition, we show that ADAM28 knock-out mice also displayed reduced body weight, elevated high density lipoprotein cholesterol levels, and reductions in blood urea nitrogen, alkaline phosphatase, and aspartate aminotransferase. The results of this study provide important insights into the pathogenic role of the metalloproteinase ADAM28 in the metabolic syndrome and suggests that downregulation of ADAM28 may be a potential therapeutic strategy in the metabolic syndrome.

  12. Preventing violence, exploitation and abuse of persons with mental disabilities: Exploring the monitoring implications of Article 16 of the United Nations Convention on the Rights of Persons with Disabilities.

    Science.gov (United States)

    Laing, Judy

    Article 16 of the United Nations Convention on the Rights of Persons with Disabilities includes the right to be free from all forms of violence, exploitation and abuse. In pursuance of this aim, Article 16 (3) imposes an obligation on States Parties to 'ensure that all facilities and programmes designed to serve persons with disabilities are effectively monitored by independent authorities'. Effective independent monitoring is viewed as a key mechanism to help safeguard people from violence, exploitation and abuse. This is highly pertinent in the wake of the highly publicized abuse of patients in care homes and hospitals in England in the last few years. This article examines the monitoring requirements of Article 16 and, by drawing on the author's research into the Care Quality Commission (the national health and social care regulator and mental health monitor) in England, assesses the extent to which independent inspection of hospitals and care homes can play a part in realizing Article 16(3) to prevent violence, abuse and exploitation of persons with mental disabilities. The potential scope and reach of Article 16 is extremely wide: this brings with it great potential but, at the same time, significant challenges for achieving effecting monitoring. Some of these challenges are explored and the paper concludes with some consideration of how monitors/inspectors, such as the Care Quality Commission in England, can strengthen their protection for people with mental disabilities, in line with the ethos and aspirations of the CRPD.

    Research highlights: → Strong ADAM15 expression is found in normal melanocytes. → ADAM15 expression is significantly downregulated in patients with melanoma metastasis. → TGF-β can downregulate ADAM15 expression in melanoma cells. → Overexpression of ADAM15 in melanoma cells inhibits migration, proliferation and invasion of melanoma cells. → Conclusion: ADAM15 represents an tumor suppressor protein in melanoma. -- Abstract: In a mouse melanoma metastasis model it has been recently shown that ADAM15 overexpression in melanoma cells significantly reduced the number of metastatic nodules on the lung. Unfortunately, the expression of ADAM15 in human melanoma tissue has not been determined so far. In our study, we characterized the expression of ADAM15 in tissue micro-arrays of patients with primary melanoma with melanoma metastasis. ADAM15 was expressed in melanocytes and endothelial cells of benign nevi and melanoma tissue. Importantly, ADAM15 was significantly downregulated in melanoma metastasis compared to primary melanoma. We further demonstrate that IFN-γ and TGF-β downregulate ADAM15 protein levels in melanoma cells. To investigate the role of ADAM15 in melanoma progression, we overexpressed ADAM15 in melanoma cells. Importantly, overexpression of ADAM15 in melanoma cells reduced the migration, invasion and the anchorage dependent and independent cell growth of melanoma cells. In summary, the downregulation of ADAM15 plays an important role in melanoma progression and ADAM15 act as a tumorsuppressor in melanoma.

    2012-01-01

    Tumor necrosis factor-α–converting enzyme (TACE; also known as ADAM17) is a proteolytic sheddase that is responsible for the cleavage of several membrane-bound molecules. We report that TACE cleaves neuregulin-1 (NRG1) type III in the epidermal growth factor domain, probably inactivating it (as assessed by deficient activation of the phosphatidylinositol-3-OH kinase pathway), and thereby negatively regulating peripheral nervous system (PNS) myelination. Lentivirus-mediated knockdown of TACE in vitro in dorsal root ganglia neurons accelerates the onset of myelination and results in hypermyelination. In agreement, motor neurons of conditional knockout mice lacking TACE specifically in these cells are significantly hypermyelinated, and small-caliber fibers are aberrantly myelinated. Further, reduced TACE activity rescues hypomyelination in NRG1 type III haploinsufficient mice in vivo. We also show that the inhibitory effect of TACE is neuron-autonomous, as Schwann cells lacking TACE elaborate myelin of normal thickness. Thus, TACE is a modulator of NRG1 type III activity and is a negative regulator of myelination in the PNS. PMID:21666671

Inherent in this request is the goal of learning from a non-nuclear procurement process in order to offer insights for those working in the field on the short- and long-term management of nuclear waste. In particular, I have been asked to comment on the learning experience from the proposed engagement of the Adams Mine Landfill that became the focus of an intense four-day debate before Toronto's City Council and was propelled into international news linked to Toronto's Olympic bid. I would like to extend my thanks to Natural Resources Canada for their support of my participation in the NEA Conference.

    Full text: The research group is dedicated to computational materials science, mostly applying and developing methods based on density functional theory (DFT). Methodological developments concern excited state properties but also the improvement of ground state calculations, both through the implementation of new functionals and the combination of DFT with manybody perturbation theory. Such a procedure may be driven by materials under investigation, which range from conventional inorganic semiconductors via organic semiconductors to complex nanostructures, and from simple metals via metal alloys to superconductors. Some of the most recent research projects are embedded into research networks, such as the NFN interface controlled and functionalized organic films, or the ERA Nanoscience Project NaPhoD - Nano-Hybrids for photonic devices. Another line of research is dedicated to metal alloys and complex interfaces, carried out within the framework of the COMET program recently established in Leoben. All this work requires high-performance computing power, which was realized in the computer cluster ADAM installed at the Montanuniversitaet. (author)

  5. Who taught Adam to speak?1

    Directory of Open Access Journals (Sweden)

    Arthur C. Custance

    1994-03-01

    Full Text Available It is taken for granted that the first man, being half-ape, 'spoke’ by copying them. Research shows that such grunts and cries cannot ‘evolve' into cultured speech because the speech organs and brain structure required for human language are entirety different from those needed for of animal communication. The difference in animal and human thinking processes is not merely one of degree but rather of kind. This difference is seen in the use of signs vs. symbols, of emotional and situational language v.v. conceptual, objective language. No animal communication system can account for the human one. Perhaps, then, speech is instinctive? No, for people, however primitive, have been found without a language. Yet unless spoken to, one does not learn to speak as demonstrated by feral (wild children and deaf-mutes(like Helen Keller. So the question is - who spoke to the first human being - Adam to teach him? About all that scientific investigation can do is to demonstrate what cannot be the origin of this extraordinary trait of human nature. The only light we have is from revelation. The first two chapters of Genesis not only tell us Who spoke first but also how the process of language was acquired. But the implications of the necessity of this unique faculty in terms of his humanity and the purpose of his very creation are profound.

    Full Text Available In 1776 Adam Smith raised the matter that an invisible hand was the one which moved the markets to obtain its efficiency. Despite in the present paper we are going to raise the hypothesis, that this invisible hand is in fact the confidence that each person feels when he is going to do business. That in addition it is unique, because it is different from the confidence of the others and that is a variable nonlinear that essentially is ligatured to respective personal histories. For that we are going to take as its bases the paper by Leopoldo Abadía (2009, with respect to the financial economy crisis that happened in 2007-2008, to evidence the form in which confidence operates. Therefore the contribution that we hope to do with this paper is to emphasize that, the level of confidence of the different actors, is the one which really moves the markets, (therefore the economy and that the crisis of the subprime mortgages is a confidence crisis at world-wide level.

    Child abuse is common in most, if not all, Western nations; it probably occurs worldwide. It may be a major factor in the increase in violence throughout much of the world. Radiologists who treat children should think of the possibilitys of abuse whenever they diagnose a fracture, intracranial bleeding or visceral injury, especially when the history is not compatible with their findings. Metaphyseal 'corner' fractures in infants usually are caused by abuse. Less than 20% of abused children, however, present injuries that can be recognized by radiologic techniques. Consequently normal roentgenograms, nuclear medicine scans, ultrasound studies, and computed tomograms do not exclude child abuse.

  13. Taking Charge: Walter Sydney Adams and the Mount Wilson Observatory

    Brashear, R.

    2004-12-01

    The growing preeminence of American observational astronomy in the first half of the 20th century is a well-known story and much credit is given to George Ellery Hale and his skill as an observatory-building entrepreneur. But a key figure who has yet to be discussed in great detail is Walter Sydney Adams (1876-1956), Hale's Assistant Director at Mount Wilson Observatory. Due to Hale's illnesses, Adams was Acting Director for much of Hale's tenure, and he became the second Director of Mount Wilson from 1923 to 1946. Behind his New England reserve Adams was instrumental in the growth of Mount Wilson and thus American astronomy in general. Adams was hand-picked by Hale to take charge of stellar spectroscopy work at Yerkes and Mount Wilson and the younger astronomer showed tremendous loyalty to Hale and Hale's vision throughout his career. As Adams assumed the leadership role at Mount Wilson he concentrated on making the observatory a place where researchers worked with great freedom but maintain a high level of cooperation. This paper will concentrate on Adams's early years and look at his growing relationship with Hale and how he came to be the central figure in the early history of Mount Wilson as both a solar and stellar observatory. His education, his years at Dartmouth and Yerkes (including his unfortunate encounter with epsilon Leonis), and his formative years on Mount Wilson are all important in learning how he shaped the direction of Mount Wilson and the development of American astronomy in the first half of the 20th century. This latter history cannot be complete until we bring Adams into better focus.

  14. The ADAMs family of proteases: new biomarkers and therapeutic targets for cancer?

    LENUS (Irish Health Repository)

    Duffy, Michael J

    2011-06-09

    Abstract The ADAMs are transmembrane proteins implicated in proteolysis and cell adhesion. Forty gene members of the family have been identified, of which 21 are believed to be functional in humans. As proteases, their main substrates are the ectodomains of other transmembrane proteins. These substrates include precursor forms of growth factors, cytokines, growth factor receptors, cytokine receptors and several different types of adhesion molecules. Although altered expression of specific ADAMs has been implicated in different diseases, their best-documented role is in cancer formation and progression. ADAMs shown to play a role in cancer include ADAM9, ADAM10, ADAM12, ADAM15 and ADAM17. Two of the ADAMs, i.e., ADAM10 and 17 appear to promote cancer progression by releasing HER\\/EGFR ligands. The released ligands activate HER\\/EGFR signalling that culminates in increased cell proliferation, migration and survival. Consistent with a causative role in cancer, several ADAMs are emerging as potential cancer biomarkers for aiding cancer diagnosis and predicting patient outcome. Furthermore, a number of selective ADAM inhibitors, especially against ADAM10 and ADAM17, have been shown to have anti-cancer effects. At least one of these inhibitors is now undergoing clinical trials in patients with breast cancer.

    Epidermal growth factor receptors (EGFR) are required for tumor promotion by Western diet. The metalloprotease, ADAM17 activates EGFR by releasing pro-EGFR ligands. ADAM17 is regulated by G-protein-coupled receptors, including CXCR4. Here we investigated CXCR4-ADAM17 crosstalk and examined the role of ADAM17 in tumorigenesis. We used CXCR4 inhibitor, AMD3100 and ADAM17 inhibitor, BMS566394 to assess CXCR4-ADAM17 crosstalk in colon cancer cells. We compared the expression of CXCR4 ligand, CXCL2, and ADAM17 in mice fed Western diet versus standard diet. Separately, mice were treated with marimastat, a broad-spectrum ADAM17 inhibitor, or AMD3100 to assess EGFR activation by ADAM17 and CXCR4. Using Apc-mutant Min mice, we investigated the effects of ADAM17/10 inhibitor INCB3619 on tumorigenesis. To assess the effects of colonocyte ADAM17, mice with ADAM17 conditional deletion were treated with azoxymethane (AOM). ADAM17 expression was also compared in colonocytes from primary human colon cancers and adjacent mucosa. CXCL12 treatment activated colon cancer cell EGFR signals, and CXCR4 or ADAM17 blockade reduced this activation. In vivo, Western diet increased CXCL12 in stromal cells and TGFα in colonocytes. Marimastat or AMD3100 caused >50% reduction in EGFR signals (P 2.5-fold in human malignant colonocytes. ADAM17 is a Western diet-inducible enzyme activated by CXCL12-CXCR4 signaling, suggesting the pathway: Western diet→CXCL12→CXCR4→ADAM17→TGFα→EGFR. ADAM17 might serve as a druggable target in chemoprevention strategies. Clin Cancer Res; 23(2); 549-61. ©2016 AACR. ©2016 American Association for Cancer Research.

    Receptor for advanced glycation end products (RAGE) signalling plays a critical role in the pathogenesis of cardiovascular disease. Calcitriol modulates cardiac RAGE expression. This study explored the mechanisms underlying the effect of calcitriol on RAGE and soluble RAGE (sRAGE) expression in cardiomyocytes. Western blot, ELISA, fluorometric assay and PCR analyses were used to evaluate the RAGE, sRAGE, endogenous secretory RAGE (esRAGE), Jun N-terminal kinase (JNK), and a disintegrin and metalloprotease 10 (ADAM10) expression and enzyme activity in HL-1 atrial myocytes without and with calcitriol (10 and 100 nM), nuclear factor-κB (NF-κB) inhibitor (50 μg/mL), or ADAM10 inhibitor (5 μM) incubation for 48 h. Calcitriol (10 nM) significantly reduced RAGE protein expression and increased sRAGE concentrations in HL-1 cardiomyocytes compared with control cells. These changes were associated with increased protein expression and enzyme activity of ADAM10 and higher mRNA expression of esRAGE. In the presence of ADAM10 inhibitor, however, the suppressive effect of calcitriol on RAGE was diminished. Methylglyoxal (500 μM for 10 min)-mediated JNK phosphorylation was attenuated in the presence of calcitriol (10 nM). Moreover, control and NF-κB inhibitor-treated HL-1 cells had similar RAGE and sRAGE expression, suggesting that calcitriol-mediated RAGE modulation was independent of NF-κB signalling. We showed that RAGE downregulation and increased sRAGE production by calcitriol were mediated through ADAM10 activation in cardiomyocytes. The results suggest that calcitriol has therapeutic potential in treating RAGE-mediated cardiovascular complications. © 2017 Stichting European Society for Clinical Investigation Journal Foundation.

    Equine laminitis is a debilitating disease affecting the digital laminae that suspends the distal phalanx within the hoof. While the clinical progression of the disease has been well documented, the molecular events associated with its pathogenesis remain largely unknown. We have investigated the expression of genes coding for proteins containing a Disintegrin and Metalloprotease domain (ADAM), as well as genes encoding the natural inhibitors of these enzymes (Tissue Inhibitor of MetalloProtease; TIMP) in horses with naturally acquired (acute, chronic and aggravated chronic cases collected in clinic) or experimentally-induced (black walnut extract and starch gruel models) laminitis using real time quantitative RT-PCR. Changes in expression of these enzymes and regulators may underlie the pathologic remodeling of lamellar tissue in laminitis. Genes encoding ADAMs involved in inflammation (ADAM-10 and ADAM-17), as well as those implicated in arthritis (ADAMTS-1, ADAMTS-4 and ADAMTS-5) were cloned, and the sequences used to generate specific oligonucleotide primers for the RT-qPCR experiments. Our results show that genes encoding ADAM-10 and 17 were not induced in most laminitic animals whereas ADAMTS-4 gene expression was strongly upregulated in practically all cases of experimentally induced and naturally acquired laminitis. The expression of MMP-9 and ADAMTS-5 was also increased in many of the laminitic horses. In addition, TIMP-2 gene expression was decreased in most laminitic horses, whereas expression of genes encoding other TIMPs, namely TIMP-1 and TIMP-3 was randomly increased or decreased in the various models. We conclude that elevated expression of lamellar ADAMTS-4 is a common feature of laminitis consistent with a central role of the gene product in the pathophysiology of laminitis. PMID:19131116

  17. ADAM proteases involved in inflammation are differentially altered in patients with gastritis or ulcer.

    ADAM metallopeptidase domain (ADAM)9, 10 and 17 have α-secretase activity that regulates ectodomain shedding of factors involved in inflammation, cell proliferation, angiogenesis, and wound healing. The secretase activity of ADAM proteins is known to induce an inflammatory response. However, under certain conditions, a lack of secretase activity may induce inflammation suggesting differential roles of ADAM proteins with secretase activity. To the best of our knowledge, the present study evaluated the changes in α-secretase activity and expression of associated ADAM proteases (ADAM9, 10 and 17) in the gastric mucosa of patients with gastritis and ulcers, for the first time. Gastroduedonal mucosal samples from 42 patients were snap-frozen to determine changes in α-secretase activity. Twenty-four of these patients had gastritis, 9 patients had duedonal ulcers and 9 patients did not have any pathological changes. Paraffin-embedded gastric specimens (n=32) were used for immunohistochemical detection of ADAM9, ADAM10 and ADAM17. α-secretase activity of the gastric mucosa of healthy subjects was significantly higher compared with the uninvolved mucosa of patients with gastritis or ulcer. These results were associated with the immunohistochemical staining results, which demonstrated that ADAM10 expression markedly decreased in glandular epithelial cells and ADAM9 expression was lost in foveolar epithelial cells of gastric mucosa adjacent to ulcer. However, ADAM17 expression was increased in the normal gastric mucosa of patients with bleeding peptic ulcers and in the gastric mucosa adjacent to the ulcer suggesting a counteracting role of ADAM17. Decreased ADAM9 and 10 expression, and an associated decrease in α-secretase activity may predispose to chronic gastritis and ulcer. Further studies are required to determine the possible etiological role of increased ADAM17 expression.

  2. Increased B Cell ADAM10 in Allergic Patients and Th2 Prone Mice.

    Directory of Open Access Journals (Sweden)

    Lauren Folgosa Cooley

    Full Text Available ADAM10, as the sheddase of the low affinity IgE receptor (CD23, promotes IgE production and thus is a unique target for attenuating allergic disease. Herein, we describe that B cell levels of ADAM10, specifically, are increased in allergic patients and Th2 prone WT mouse strains (Balb/c and A/J. While T cell help augments ADAM10 expression, Balb WT B cells exhibit increased ADAM10 in the naïve state and even more dramatically increased ADAM10 after anti-CD40/IL4 stimulation compared C57 (Th1 prone WT B cells. Furthermore, ADAM17 and TNF are reduced in allergic patients and Th2 prone mouse strains (Balb/c and A/J compared to Th1 prone controls. To further understand this regulation, ADAM17 and TNF were studied in C57Bl/6 and Balb/c mice deficient in ADAM10. C57-ADAM10B-/- were more adept at increasing ADAM17 levels and thus TNF cleavage resulting in excess follicular TNF levels and abnormal secondary lymphoid tissue architecture not noted in Balb-ADAM10B-/-. Moreover, the level of B cell ADAM10 as well as Th context is critical for determining IgE production potential. Using a murine house dust mite airway hypersensitivity model, we describe that high B cell ADAM10 level in a Th2 context (Balb/c WT is optimal for disease induction including bronchoconstriction, goblet cell metaplasia, mucus, inflammatory cellular infiltration, and IgE production. Balb/c mice deficient in B cell ADAM10 have attenuated lung and airway symptoms compared to Balb WT and are actually most similar to C57 WT (Th1 prone. C57-ADAM10B-/- have even further reduced symptomology. Taken together, it is critical to consider both innate B cell levels of ADAM10 and ADAM17 as well as Th context when determining host susceptibility to allergic disease. High B cell ADAM10 and low ADAM17 levels would help diagnostically in predicting Th2 disease susceptibility; and, we provide support for the use ADAM10 inhibitors in treating Th2 disease.

  3. ADAM17 silencing in mouse colon carcinoma cells: the effect on tumoricidal cytokines and angiogenesis.

    Directory of Open Access Journals (Sweden)

    Sudipta Das

    Full Text Available ADAM17 (a disintegrin and metalloprotease 17 is a major sheddase for numerous growth factors, cytokines, receptors, and cell adhesion molecules and is often overexpressed in malignant cells. It is generally accepted that ADAM17 promotes tumor development via activating growth factors from the EGF family, thus facilitating autocrine stimulation of tumor cell proliferation and migration. Here we show, using MC38CEA murine colon carcinoma model, that ADAM17 also regulates tumor angiogenesis and cytokine profile. When ADAM17 was silenced in MC38CEA cells, in vivo tumor growth and in vitro cell motility were significantly diminished, but no effect was seen on in vitro cell proliferation. ADAM17-silencing was accompanied by decreased in vitro expression of vascular endothelial growth factor-A and matrix metalloprotease-9, which was consistent with the limited angiogenesis and slower growth seen in ADAM17-silenced tumors. Among the growth factors susceptible to shedding by ADAM17, neuregulin-1 was the only candidate to mediate the effects of ADAM17 on MC38CEA motility and tumor angiogenesis. Concentrations of TNF and IFNγ, cytokines that synergistically induced proapoptotic effects on MC38CEA cells, were significantly elevated in the lysates of ADAM17-silenced tumors compared to mock transfected controls, suggesting a possible role for ADAM17 in host immune suppression. These results introduce new, complex roles of ADAM17 in tumor progression, including its impact on the anti-tumor immune response.

    Expression of ADAM12 is low in most normal tissues, but is markedly increased in numerous human cancers, including breast carcinomas. We have previously shown that overexpression of ADAM12 accelerates tumor progression in a mouse model of breast cancer (PyMT). In the present study, we found...... that ADAM12 deficiency reduces breast tumor progression in the PyMT model. However, the catalytic activity of ADAM12 appears to be dispensable for its tumor-promoting effect. Interestingly, we demonstrate that ADAM12 endogenously expressed in tumor-associated stroma in the PyMT model does not influence...... tumor progression, but that ADAM12 expression by tumor cells is necessary for tumor progression in these mice. This finding is consistent with our observation that in human breast carcinoma ADAM12 is almost exclusively located in tumor cells and only rarely seen in the tumor-associated stroma. We...

  6. Empathy's purity, sympathy's complexities; De Waal, Darwin and Adam Smith.

    Science.gov (United States)

    van der Weele, Cor

    2011-07-01

    Frans de Waal's view that empathy is at the basis of morality directly seems to build on Darwin, who considered sympathy as the crucial instinct. Yet when we look closer, their understanding of the central social instinct differs considerably. De Waal sees our deeply ingrained tendency to sympathize (or rather: empathize) with others as the good side of our morally dualistic nature. For Darwin, sympathizing was not the whole story of the "workings of sympathy"; the (selfish) need to receive sympathy played just as central a role in the complex roads from sympathy to morality. Darwin's understanding of sympathy stems from Adam Smith, who argued that the presence of morally impure motives should not be a reason for cynicism about morality. I suggest that De Waal's approach could benefit from a more thorough alignment with the analysis of the workings of sympathy in the work of Darwin and Adam Smith.

  7. Adams natural gas/diesel demonstration project

    1990-06-01

    The results of a ore-year program to demonstrate the viability of fuelling and operating diesel road vehicles on dual fuel natural gas/diesel under commercial operating conditions is presented. During this project a natural gas fuelling station designed to accomodate the specific needs of heavy trucks was constructed, and a Canada Safeway Ltd. tractor was converted to dual fuel natural gas/diesel operation. The truck accumulated more than 64,000 km during the one-year monitoring period, providing useful data in terms of comparative fuel efficiency, natural gas/diesel proportions of fuel use, operating range, and refuelling times, along with assessments of its performance by drivers and fleet management. In the dual fuel mode the truck experienced a 15% loss in thermal efficiency relative to straight diesel fuel during highway operation, and a 20% loss during local operation. Fuel cost savings resulting from the use of natural gas were not large given the increased level of fuel consumption and the purchase of natural gas at higher prices. If the fleet were to have its own natural gas fuelling station fuel cost savings would be substantially increased. Areas in which further development is needed for natural gas to emerge as a significant fuel for heavy trucks are mentioned. 3 figs., 15 tabs.

    Radiotherapy treatment of moving lesions is a challenging task in which different strategies can be used to adequately treat the tumor while sparing the surrounding tissue. The complexity of these strategies requires accurate and appropriate quality assurance tests. For this purpose, ADAM (Anthropomorphic Dynamic breAthing Model), a new phantom which simulates realistic patient breathing, was developed aiming to test the image quality and dose delivery in lung cancer treatments. ADAM reproduces a male torso complete with a moving anterior chest wall and internal parts. The phantom's external body is printed with a 3D printer using acrylonitrile butadiene styrene. Internal lungs, ribs, spinal cord, and lung tumor (LT) are made of materials that simulate human tissues. Driven by an Arduino programmable board, the lungs can move along linear or elliptical paths while the anterior chest wall moves up and down. Phantom features and usability, reproducibility of LT position in the phantom chest, internal and external motion repeatability and tumor-to-surface motion correlation were investigated. Hounsfield Units of the employed materials demonstrates the phantom adequately simulates human tissues. Tests performed with the Synchrony system confirm ADAM's suitability for respiratory internal tracking. Reproducibility of the internal structure position is within 1mm as are internal and external motion repeatability. A strong positive correlation is found between the lung and chest wall positions (R 2 =0.999). ADAM demonstrates to be suitable to be employed with gating and tracking devices used in the treatment of moving lesions. Copyright © 2017 Associazione Italiana di Fisica Medica.

    2004-11-01

    On December 7, 1941, a 60-year old dentist from Irwin, Pennsylvania, Dr. Lytle S. Adams, was driving home from a vacation at Carlsbad Caverns in New Mexico. Hours earlier, he had been gripped with amazement as he witnessed millions of bats exiting the caves of Carlsbad. Listening to his car radio on his return trip, he was shocked to hear that Japan had just attacked Pearl Harbor. Dr. Adams, outraged over this travesty, began to mentally construct a plan for U.S. retaliation. As his thoughts returned to the countless bats that had awed him, he formed a tentative plan: millions of these small, flying mammals could be connected to tiny, time-fused incendiary bombs, and then released to land on the flimsily constructed structures which dotted the cities of Japan. Within a few minutes, the bombs would explode and enflame the entire urban areas. He postulated that these immeasurable numbers of fires, spreading their devastation over such vast areas within Japanese cities would result in the enemy's speedy surrender. This article documents the futile efforts of Dr. Adams, his team and the U.S. government to develop and employ an effective, incendiary bat bomb. The recently developed atom bomb, a far more deadly weapon was used in its place.

    ADAM28, ADAM33, IL-13, IL-4 and other cytokines (IL-6 and IL-10) seem to play important roles in the persistence and maintenance of acute inflammatory processes that ultimately lead to lung remodeling and pulmonary fibrosis, which may be responsible for the high morbidity and mortality rates associated with non-pandemic acute viral pneumonias in childhood. The aim of this study was to evaluate the roles of ADAM33, ADAM28, IL4, IL6, IL10 and IL13 in the development of inflammation and alveolar fibrosis due to lethal acute respiratory infections of the lower airway in a pediatric population, especially in those with viral etiology. For this study, 193 cases were selected, and samples from the cases were processed for viral antigen detection by immunohistochemistry and then separated into two groups: virus-positive (n=68) and virus-negative (n=125). Immunohistochemistry was performed to assess the presence of metalloproteinases (ADAM33 and ADAM28) and inflammatory cytokines (IL-4, IL-13, IL-6, IL-10) in the alveolar septa. The virus-positive group showed stronger immunolabeling for ADAM33, ADAM28, IL-4 and IL-13 (pplay important roles in pulmonary inflammatory reactions elicited against etiological viral agents. In addition, these mediators may affect the process of lung remodeling and the development of pulmonary fibrosis. Copyright © 2014 Elsevier B.V. All rights reserved.

    The inhibition of a disintegrin and metalloproteinase (ADAM) has the potential to become a novel approach for natural killer (NK) cell-based cancer immunotherapy. Thus, the aim of this study was to investigate the influence of ADAM10 and ADAM17 inhibitors on expanded NK cell to enhance antibody-dependent cellular cytotoxicity (ADCC) in breast cancer cell lines. NK cells were expanded in medium supplemented with an ADAM10 or ADAM17 inhibitor to prevent the shedding of soluble CD16/FcγRIII. The expression level of CD16 and production of interferon-gamma (IFN-γ) was detected by flow cytometry using specific antibodies. ADCC activity of expanded NK cells was estimated in trastuzumab treated breast cancer cell lines such as MCF-7, MDA-MB-231, SKBR3, and BT-474 cells. The ADAM17 inhibitor increased the purity of expanded NK cells to 90% after 14 days at 5 and 10 μM in vitro (p=0.043). However, the expansion rate of NK cells was decreased at 10 μM of the ADAM 17 inhibitor (p=0.043). Inhibition of ADAM10 suppressed the expansion of NK cells, although the NK purity was increased at 1 μM of the inhibitor. The expression of CD16 was significantly increased at 1 and 5 μM of the ADAM17 inhibitor (p=0.046, 0.028, respectively) during the culturing period. Inhibition of ADAM10 reduced the expression of CD16 on NK cells. The cytotoxic activity of the ADAM17 inhibitor treated NK cells against MCF-7 (p=0.039) and BT-474 (p=0.027) cells was significantly elevated. The ADCC activity of NK cells treated with 5 μM of ADAM17 inhibitor was significantly increased against SKBR-3 and BT-474 (p=0.027). Inhibition of ADAM17 increased the production of IFN-γ in expanded NK cells. The inhibition of ADAM17 enhanced the purity of expanded NK cells and the ADCC activity of these cells against trastuzumab treated breast cancer cell lines.

    Full Text Available Abstract Background ADAM11 is a member of the ADAM gene family and is mainly expressed in the nervous system. It is thought to be an adhesion molecule, since it has a disintegrin-like domain related to cell-cell or cell-matrix interactions. To elucidate the physiological functions of ADAM11, we generated ADAM11-deficient mice by means of gene targeting. Results ADAM11-deficient mice were apparently normal, and survived more than one year with no major histological abnormalities in the brain or spinal cord. Because ADAM11 is highly expressed in the hippocampus and cerebellum, we have examined ADAM11 mutant mice for learning using visual and hidden water maze tasks, and their motor coordination using a rotating rod task. Our results showed that their visual water maze task results are normal, but the hidden water maze and rotating rod task skills are impaired in ADAM11-deficient mice. Conclusion Our results indicate that ADAM11 mutation does not affect cell migration and differentiation during development, but affects learning and motor coordination. Thus, ADAM11 might play an important signalling or structural role as a cell adhesion molecule at the synapse, and may thus participate in synaptic regulation underlying behavioural changes.

    ANCA-associated vasculitides are characterized by inflammatory destruction of small vessels accompanied by enhanced cleavage of membrane-bound proteins. One of the main proteases responsible for ectodomain shedding is disintegrin and metalloproteinase domain-containing protein 17 (ADAM17). Given its potential role in aggravating vascular dysfunction, we examined the role of ADAM17 in active proteinase-3 (PR3)-positive ANCA-associated vasculitis (AAV). ADAM17 concentration was significantly increased in plasma samples from patients with active PR3-AAV compared with samples from patients in remission or from other controls with renal nonvascular diseases. Comparably, plasma levels of the ADAM17 substrate syndecan-1 were significantly enhanced in active AAV. We also observed that plasma-derived ADAM17 retained its specific proteolytic activity and was partly located on extracellular microparticles. Transcript levels of ADAM17 were increased in blood samples of patients with active AAV, but those of ADAM10 or tissue inhibitor of metalloproteinases 3, which inhibits ADAMs, were not. We also performed a microRNA (miR) screen and identified miR-634 as significantly upregulated in blood samples from patients with active AAV. In vitro, miR-634 mimics induced a proinflammatory phenotype in monocyte-derived macrophages, with enhanced expression and release of ADAM17 and IL-6. These data suggest that ADAM17 has a prominent role in AAV and might account for the vascular complications associated with this disease. PMID:25788529

    An important, irreversible step in many signalling pathways is the shedding of membrane-anchored proteins. A Disintegrin And Metalloproteinase (ADAM) 17 is one of the major sheddases involved in a variety of physiological and pathophysiological processes including regeneration, differentiation, and cancer progression. This central role in signalling implies that ADAM17 activity has to be tightly regulated, including at the level of localisation. Most mature ADAM17 is localised intracellularly, with only a small amount at the cell surface. We found that ADAM17 is constitutively internalised by clathrin-coated pits and that physiological stimulators such as GPCR ligands induce ADAM17-mediated shedding, but do not alter the cell-surface abundance of the protease. In contrast, the PKC-activating phorbol ester PMA, often used as a strong inducer of ADAM17, causes not only proteolysis by ADAM17 but also a rapid increase of the mature protease at the cell surface. This is followed by internalisation and subsequent degradation of the protease. Eventually, this leads to a substantial downregulation of mature ADAM17. Our results therefore imply that physiological activation of ADAM17 does not rely on its relocalisation, but that PMA-induced PKC activity drastically dysregulates the localisation of ADAM17.

  20. ADAM17 deletion in thymic epithelial cells alters aire expression without affecting T cell developmental progression.

    Full Text Available Cellular interactions between thymocytes and thymic stromal cells are critical for normal T cell development. Thymic epithelial cells (TECs are important stromal niche cells that provide essential growth factors, cytokines, and present self-antigens to developing thymocytes. The identification of genes that mediate cellular crosstalk in the thymus is ongoing. One candidate gene, Adam17, encodes a metalloprotease that functions by cleaving the ectodomain of several transmembrane proteins and regulates various developmental processes. In conventional Adam17 knockout mice, a non-cell autonomous role for ADAM17 in adult T cell development was reported, which strongly suggested that expression of ADAM17 in TECs was required for normal T cell development. However, knockdown of Adam17 results in multisystem developmental defects and perinatal lethality, which has made study of the role of Adam17 in specific cell types difficult. Here, we examined T cell and thymic epithelial cell development using a conditional knockout approach.We generated an Adam17 conditional knockout mouse in which floxed Adam17 is deleted specifically in TECs by Cre recombinase under the control of the Foxn1 promoter. Normal T cell lineage choice and development through the canonical αβ T cell stages was observed. Interestingly, Adam17 deficiency in TECs resulted in reduced expression of the transcription factor Aire. However, no alterations in the patterns of TEC phenotypic marker expression and thymus morphology were noted.In contrast to expectation, our data clearly shows that absence of Adam17 in TECs is dispensable for normal T cell development. Differentiation of TECs is also unaffected by loss of Adam17 based on phenotypic markers. Surprisingly, we have uncovered a novel genetic link between Adam17and Aire expression in vivo.

  1. Scissor sisters: regulation of ADAM10 by the TspanC8 tetraspanins.

    A disintegrin and metalloprotease 10 (ADAM10) is a ubiquitously expressed transmembrane protein which is essential for embryonic development through activation of Notch proteins. ADAM10 regulates over 40 other transmembrane proteins and acts as a 'molecular scissor' by removing their extracellular regions. ADAM10 is also a receptor for α-toxin, a major virulence factor of Staphylococcus aureus Owing to the importance of its substrates, ADAM10 is a potential therapeutic target for cancer, neurodegenerative diseases such as Alzheimer's and prion diseases, bacterial infection and inflammatory diseases such as heart attack, stroke and asthma. However, targetting ADAM10 is likely to result in toxic side effects. The tetraspanins are a superfamily of 33 four-transmembrane proteins in mammals which interact with and regulate specific partner proteins within membrane nanodomains. Tetraspanins appear to have a cone-shaped structure with a cholesterol-binding cavity, which may enable tetraspanins to undergo cholesterol-regulated conformational change. An emerging paradigm for tetraspanin function is the regulation of ADAM10 by the TspanC8 subgroup of tetraspanins, namely Tspan5, 10, 14, 15, 17 and 33. This review will describe how TspanC8s are required for ADAM10 trafficking from the endoplasmic reticulum and its enzymatic maturation. Moreover, different TspanC8s localise ADAM10 to different subcellular localisations and may cause ADAM10 to adopt distinct conformations and cleavage of distinct substrates. We propose that ADAM10 should now be regarded as six different scissor proteins depending on the interacting TspanC8. Therapeutic targetting of specific TspanC8/ADAM10 complexes could allow ADAM10 targetting in a cell type- or substrate-specific manner, to treat certain diseases while minimising toxicity. © 2017 The Author(s).

    Trophoblast progenitor cell differentiation towards the extravillous trophoblast (EVT) lineage initiates within proximal regions of anchoring columns of first trimester placental villi. While molecular processes controlling the initial stages of progenitor cell differentiation along the EVT pathway have been described, much remains unknown about factors important in distal column cell differentiation into invasive EVTs. ADAMs are proteases that regulate growth factor signaling, cell-matrix adhesion, and matrix proteolysis, and thus impact many processes relevant in placentation. Global gene expression studies identified the ADAM subtype, ADAM28, to be highly expressed in EVT-like trophoblasts, suggesting that it may play a role in EVT function. This study aims to test the functional importance of ADAM28 in column cell outgrowth and maintenance. ADAM28 mRNA levels and protein localization were determined by qPCR and immunofluorescence microscopy analyses in purified placental villi cell populations and tissues. ADAM28 function in trophoblast column outgrowth was examined using ADAM28-targetting siRNAs in Matrigel-imbedded placental explant cultures. Within placental villi, ADAM28 mRNA levels were highest in HLA-G + column trophoblasts, and consistent with this, ADAM28 was preferentially localized to HLA-G + trophoblasts within distal anchoring columns and decidual tissue. siRNA-directed loss of ADAM28 impaired trophoblast column outgrowth and resulted in increased apoptosis in matrix-invading trophoblasts. Our findings suggest that ADAM28 promotes column outgrowth by providing survival cues within anchoring column cells. This study also provides insight into a possible role for ADAM28 in driving differentiation of column trophoblasts into invasive HLA-G + EVT subsets. Copyright © 2017 Elsevier Ltd.

    The mammalian epididymis is a highly convoluted tubule that connects the testis to the vas deferens. Its proper functions in sperm transport, storage, and maturation are essential for male reproduction. One of the genes predominantly expressed in the epididymis is ADAM7 (a disintegrin and metalloprotease 7). Previous studies have shown that ADAM7 synthesized in the epididymis is secreted into the epididymal lumen and is then transferred to sperm membranes, where it forms a chaperone complex that is potentially involved in sperm fertility. In this study, we generated and analyzed mice with a targeted disruption in the Adam7 gene. We found that the fertility of male mice was modestly but significantly reduced by knockout of Adam7. Histological analyses revealed that the cell heights of the epithelium were dramatically decreased in the caput of the epididymis of Adam7-null mice, suggesting a requirement for ADAM7 in maintaining the integrity of the epididymal epithelium. We found that sperm from Adam7-null mice exhibit decreased motility, tail deformation, and altered tyrosine phosphorylation, indicating that the absence of ADAM7 leads to abnormal sperm functions and morphology. Western blot analyses revealed reduced levels of integral membrane protein 2B (ITM2B) and ADAM2 in sperm from Adam7-null mice, suggesting a requirement for ADAM7 in normal expression of sperm membrane proteins involved in sperm functions. Collectively, our study demonstrates for the first time that ADAM7 is required for normal fertility and is important for the maintenance of epididymal integrity and for sperm morphology, motility, and membrane proteins. © 2015 by the Society for the Study of Reproduction, Inc.

    The transmembrane protease ADAM9 is frequently upregulated in human cancers, and it promotes tumour progression in mice.In vitro, ADAM9 regulates cancer cell adhesion and migration by interacting with integrins. However, how ADAM9 modulates integrin functions is not known. We here show that ADAM9......, and both internalization and subsequent degradation of β1 integrin are significantly decreased in ADAM9-silenced cells, with no effect on β1 integrin recycling. Accordingly, the formation of focal adhesions and actin stress fibres in ADAM9-silenced cells is altered, possibly explaining the reduction...... in cell adhesion and migration in these cells. Taken together, our data provide mechanistic insight into the ADAM9-integrin interaction, demonstrating that ADAM9 regulates β1 integrin endocytosis. Moreover, our findings indicate that the reduced migration of ADAM9-silenced cells is, at least in part...

    Full Text Available Abstract Study objective The pathogenesis of chronic obstructive pulmonary disease (COPD is characterized by an interaction of environmental influences, particularly cigarette smoking, and genetic determinants. Given the global increase in COPD, research on the genomic variants that affect susceptibility to this complex disorder is reviving. In the present study, we investigated whether single nucleotide polymorphisms in 'a disinter-grin and metalloprotease' 33 (ADAM33 are associated with the development and course of COPD. Patients and design We genotyped 150 German COPD patients and 152 healthy controls for the presence of the F+1 and S_2 SNPs in ADAM 33 that lead to the base pair exchange G to A and C to G, respectively. To assess whether these genetic variants are influential in the course of COPD, we subdivided the cohort into two subgroups comprising 60 patients with a stable and 90 patients with an unstable course of disease. Results In ADAM33, the frequency of the F+1 A allele was 35.0% among stable and 43.9% among unstable COPD subjects, which was not significantly different from the 35.5% found in the controls (P = 0.92 and P = 0.07, respectively. The frequency of the S_2 mutant allele in subjects with a stable COPD was 23.3% (P = 0.32, in subjects with an unstable course 30.6% (P = 0.47. Conclusion The study shows that there is no significant difference in the distribution of the tested SNPs between subjects with and without COPD. Furthermore, these polymorphisms appear to have no consequences for the stability of the disease course.

    Alveolar leukocyte recruitment is a hallmark of acute lung inflammation and involves transmigration of leukocytes through endothelial and epithelial layers. The disintegrin and metalloproteinase (ADAM) 8 is expressed on human isolated leukocytic cells and can be further upregulated on cultured endothelial and epithelial cells by proinflammatory cytokines. By shRNA-mediated knockdown we show that leukocytic ADAM8 is required on monocytic THP-1 cells for chemokine-induced chemotaxis as well as transendothelial and transepithelial migration. Furthermore, ADAM8 promotes α L -integrin upregulation and THP-1 cell adhesion to endothelial cells. On endothelial cells ADAM8 enhances transendothelial migration and increases cytokine-induced permeability. On epithelial cells the protease facilitates migration in a wound closure assay but does not affect transepithelial leukocyte migration. Blood leukocytes and bone marrow-derived macrophages (BMDM) from ADAM8-deficient mice show suppressed chemotactic response. Intranasal application of LPS to mice is accompanied with ADAM8 upregulation in the lung. In this model of acute lung inflammation ADAM8-deficient mice are protected against leukocyte infiltration. Finally, transfer experiments of BMDM in mice indicate that ADAM8 exerts a promigratory function predominantly on leukocytes. Our study provides in vitro and in vivo evidence that ADAM8 on leukocytes holds a proinflammatory function in acute lung inflammation by promoting alveolar leukocyte recruitment.

    Growth disorders of the craniofacial bones may lead to craniofacial deformities. The majority of maxillofacial bones are derived from cranial neural crest cells via intramembranous bone formation. Any interruption of the craniofacial skeleton development process might lead to craniofacial malformation. A disintegrin and metalloprotease (ADAM)10 plays an essential role in organ development and tissue integrity in different organs. However, little is known about its function in craniofacial bone formation. Therefore, we investigated the role of ADAM10 in the developing craniofacial skeleton, particularly during typical mandibular bone development. First, we showed that ADAM10 was expressed in a specific area of the craniofacial bone and that the expression pattern dynamically changed during normal mouse craniofacial development. Then, we crossed wnt1-cre transgenic mice with adam10-flox mice to generate ADAM10 conditional knockout mice. The stereomicroscopic, radiographic, and von Kossa staining results showed that conditional knockout of ADAM10 in cranial neural crest cells led to embryonic death, craniofacial dysmorphia and bone defects. Furthermore, we demonstrated that impaired mineralization could be triggered by decreased osteoblast differentiation, increased cell death. Overall, these findings show that ADAM10 plays an essential role in craniofacial bone development. -- Highlights: •We firstly reported that ADAM10 was essentially involved in maxillofacial bone development. •ADAM10 cKO mice present craniofacial dysmorphia and bone defects. •Impaired osteoblast differentiation,proliferation and apoptosis underlie the bone deformity.

  9. The pleiotropic roles of ADAM9 in the biology of solid tumors.

    Science.gov (United States)

    Oria, Victor O; Lopatta, Paul; Schilling, Oliver

    2018-03-17

    A disintegrin and a metalloprotease (ADAM) 9 is a metzincin cell-surface protease involved in several biological processes such as myogenesis, fertilization, cell migration, inflammatory response, proliferation, and cell-cell interactions. ADAM9 has been found over-expressed in several solid tumors entities such as glioma, melanoma, prostate cancer, pancreatic ductal adenocarcinoma, gastric, breast, lung, and liver cancers. Immunohistochemical analyses highlight ADAM9 expression by actual cancer cells and associate its abundant presence with clinicopathological features such as shortened overall survival, poor tumor grade, de-differentiation, therapy resistance, and metastasis formation. In each of these tumors, ADAM9 may contribute to tumor biology via proteolytic or non-proteolytic mechanisms. For example, in liver cancer, ADAM9 has been found to shed MHC class I polypeptide-related sequence A, contributing towards the evasion of tumor immunity. ADAM9 may also contribute to tumor biology in non-proteolytic ways probably through interaction with different integrins. For example, in melanoma, the interaction between ADAM9 and β1 integrins facilitates tumor stroma cross talks, which then promotes invasion and metastasis via the activation of MMP1 and MMP2. In breast cancer, the interaction between β1 integrins on endothelial cells and ADAM9 on tumor cells facilitate tumor cell extravasation and invasion to distant sites. This review summarizes the present knowledge on ADAM9 in solid cancers, and the different mechanisms which it employ to drive tumor progression.

  11. John Adams's Montesquieuean Moment: Enlightened Historicism in the Discourses on Davila.

    Science.gov (United States)

    Green, Jonathan

    2016-01-01

    At the outset of the French Revolution John Adams penned a series of Discourses of Davila, philosophical ruminations on the sixteenth-century French Wars of Religion. Recent historians have read these Discourses in terms of Adams's Machiavellianism-his conviction that men's passions lead to violence, if unrestrained. But this reading overlooks the extent to which Adams intended his Discourses as a particular investigation into the French nation's character, and into whether the revolutionaries could lay claim to a native, French tradition of mixed constitutional government. Situating the Discourses vis-à-vis Adams's contemporaneous reading of Montesquieu, this article argues for an underappreciated historicist dimension to his thought.

  12. ADAM10 Is Involved in Cell Junction Assembly in Early Porcine Embryo Development.

    Directory of Open Access Journals (Sweden)

    Jeongwoo Kwon

    Full Text Available ADAM10 (A Disintegrin and Metalloprotease domain-containing protein 10 is a cell surface protein with a unique structure possessing both potential adhesion and protease domains. However, the role of ADAM10 in preimplantation stage embryos is not clear. In this study, we examined the expression patterns and functional roles of ADAM10 in porcine parthenotes during preimplantation development. The transcription level of ADAM10 dramatically increased from the morula stage onward. Immunostaining revealed that ADAM10 was present in both the nucleus and cytoplasm in early cleavage stage embryos, and localized to the apical region of the outer cells in morula and blastocyst embryos. Knockdown (KD of ADAM10 using double strand RNA did not alter preimplantation embryo development until morula stage, but resulted in significantly reduced development to blastocyst stage. Moreover, the KD blastocyst showed a decrease in gene expression of adherens and tight junction (AJ/TJ, and an increase in trophectoderm TJ permeability by disrupting TJ assembly. Treatment with an ADAM10 specific chemical inhibitor, GI254023X, at the morula stage also inhibited blastocyst development and led to disruption of TJ assembly. An in situ proximity ligation assay demonstrated direct interaction of ADAM10 with coxsackie virus and adenovirus receptor (CXADR, supporting the involvement of ADAM10 in TJ assembly. In conclusion, our findings strongly suggest that ADADM10 is important for blastocyst formation rather than compaction, particularly for TJ assembly and stabilization in preimplantation porcine parthenogenetic development.

    In the nuclear research plant at Juelich a new heating system is at present being developed as part of the Nuclear Long-distance Heating Project. Helium is heated up in a high-temperature reactor. The heat chemically converts a gas mixture in a reformer plant (EVE). The gases 'charged' with energy can be transported through tubes over any distance required at ambient temperatures. In a methanisation plant (ADAM) the gases react with one another, releasing the energy in the form of heat which can be used for heating air or water. (orig.) [de

  4. ADAM33 gene silencing by promoter hypermethylation as a molecular marker in breast invasive lobular carcinoma

    Directory of Open Access Journals (Sweden)

    de Souza Emanuel M

    2009-03-01

    Full Text Available Abstract Background ADAM33 protein is a member of the family of transmembrane glycoproteins composed of multidomains. ADAM family members have different activities, such as proteolysis and adhesion, making them good candidates to mediate the extracellular matrix remodelling and changes in cellular adhesion that characterise certain pathologies and cancer development. It was reported that one family member, ADAM23, is down-regulated by promoter hypermethylation. This seems to correlate with tumour progression and metastasis in breast cancer. In this study, we explored the involvement of ADAM33, another ADAM family member, in breast cancer. Methods First, we analysed ADAM33 expression in breast tumour cell lines by RT-PCR and western blotting. We also used 5-aza-2'-deoxycytidine (5azadCR treatment and DNA bisulphite sequencing to study the promoter methylation of ADAM33 in breast tumour cell lines. We evaluated ADAM33 methylation in primary tumour samples by methylation specific PCR (MSP. Finally, ADAM33 promoter hypermethylation was correlated with clinicopathological data using the chi-square test and Fisher's exact test. Results The expression analysis of ADAM33 in breast tumour cell lines by RT-PCR revealed gene silencing in 65% of tumour cell lines. The corresponding lack of ADAM33 protein was confirmed by western blotting.

    ADAM33 protein is a member of the family of transmembrane glycoproteins composed of multidomains. ADAM family members have different activities, such as proteolysis and adhesion, making them good candidates to mediate the extracellular matrix remodelling and changes in cellular adhesion that characterise certain pathologies and cancer development. It was reported that one family member, ADAM23, is down-regulated by promoter hypermethylation. This seems to correlate with tumour progression and metastasis in breast cancer. In this study, we explored the involvement of ADAM33, another ADAM family member, in breast cancer. First, we analysed ADAM33 expression in breast tumour cell lines by RT-PCR and western blotting. We also used 5-aza-2'-deoxycytidine (5azadCR) treatment and DNA bisulphite sequencing to study the promoter methylation of ADAM33 in breast tumour cell lines. We evaluated ADAM33 methylation in primary tumour samples by methylation specific PCR (MSP). Finally, ADAM33 promoter hypermethylation was correlated with clinicopathological data using the chi-square test and Fisher's exact test. The expression analysis of ADAM33 in breast tumour cell lines by RT-PCR revealed gene silencing in 65% of tumour cell lines. The corresponding lack of ADAM33 protein was confirmed by western blotting. We also used 5-aza-2'-deoxycytidine (5-aza-dCR) demethylation and bisulphite sequencing methodologies to confirm that gene silencing is due to ADAM33 promoter hypermethylation. Using MSP, we detected ADAM33 promoter hypermethylation in 40% of primary breast tumour samples. The correlation between methylation pattern and patient's clinicopathological data was not significantly associated with histological grade; tumour stage (TNM); tumour size; ER, PR or ERBB2 status; lymph node status; metastasis or recurrence. Methylation frequency in invasive lobular carcinoma (ILC) was 76.2% compared with 25.5% in invasive ductal carcinoma (IDC), and this difference was

  6. The futility of utility: how market dynamics marginalize Adam Smith

    McCauley, Joseph L.

    2000-10-01

    Economic theorizing is based on the postulated, nonempiric notion of utility. Economists assume that prices, dynamics, and market equilibria are supposed to be derived from utility. The results are supposed to represent mathematically the stabilizing action of Adam Smith's invisible hand. In deterministic excess demand dynamics I show the following. A utility function generally does not exist mathematically due to nonintegrable dynamics when production/investment are accounted for, resolving Mirowski's thesis. Price as a function of demand does not exist mathematically either. All equilibria are unstable. I then explain how deterministic chaos can be distinguished from random noise at short times. In the generalization to liquid markets and finance theory described by stochastic excess demand dynamics, I also show the following. Market price distributions cannot be rescaled to describe price movements as ‘equilibrium’ fluctuations about a systematic drift in price. Utility maximization does not describe equilibrium. Maximization of the Gibbs entropy of the observed price distribution of an asset would describe equilibrium, if equilibrium could be achieved, but equilibrium does not describe real, liquid markets (stocks, bonds, foreign exchange). There are three inconsistent definitions of equilibrium used in economics and finance, only one of which is correct. Prices in unregulated free markets are unstable against both noise and rising or falling expectations: Adam Smith's stabilizing invisible hand does not exist, either in mathematical models of liquid market data, or in real market data.

    Full Text Available The influence of asthma candidate genes on the development from wheeze to asthma in young children still needs to be defined.To link genetic variants in asthma candidate genes to progression of wheeze to persistent wheeze into childhood asthma.In a prospective study, children with recurrent wheeze from the ADEM (Asthma DEtection and Monitoring study were followed until the age of six. At that age a classification (transient wheeze or asthma was based on symptoms, lung function and medication use. In 198 children the relationship between this classification and 30 polymorphisms in 16 asthma candidate genes was assessed by logistic regression. In case of an association based on a p<0.10, replication analysis was performed in an independent birth cohort study (KOALA study, n = 248 included for the present analysis.In the ADEM study, the minor alleles of ADAM33 rs511898 and rs528557 and the ORMDL3/GSDMB rs7216389 polymorphisms were negatively associated, whereas the minor alleles of IL4 rs2243250 and rs2070874 polymorphisms were positively associated with childhood asthma. When replicated in the KOALA study, ADAM33 rs528557 showed a negative association of the CG/GG-genotype with progression of recurrent wheeze into childhood asthma (0.50 (0.26-0.97 p = 0.04 and no association with preschool wheeze.Polymorphisms in ADAM33, ORMDL3/GSDMB and IL4 were associated with childhood asthma in a group of children with recurrent wheeze. The replication of the negative association of the CG/GG-genotype of rs528557 ADAM33 with childhood asthma in an independent birth cohort study confirms that a compromised ADAM33 gene may be implicated in the progression of wheeze into childhood asthma.

    This article provides an overview on prescription drug abuse and highlights a number of related legislative bills introduced during the 112th Congress in response to this growing epidemic. Prescription drug abuse has emerged as the nation's fastest growing drug problem. Although prescription drugs have been used effectively and appropriately for decades, deaths from prescription pain medicine in particular have reached epidemic proportions. Bills related to prescription drug abuse introduced during the 112th Congress focus on strengthening provider and consumer education, tracking and monitoring prescription drug abuse, improving data collection on drug overdose fatalities, combating fraud and abuse in Medicare and Medicaid programs, reclassifying drugs to make them more difficult to prescribe and obtain, and enforcing stricter penalties for individuals who operate scam pain clinics and sell pain pills illegitimately. This article underscores the importance of a multifaceted approach to combating prescription drug abuse and concludes with implications for nursing. Copyright © 2013. Published by Mosby, Inc.

    A radiopharmaceutical, {sup 123}I-labeled 2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine ([{sup 123}I]ADAM), has been developed recently for evaluation of how serotonin transporters (SERT) function in the brain. However, the detailed biodistribution and specific binding in certain brain areas are not well investigated. In this study, both phosphor plate imaging and microautoradiography were applied to explore the binding characteristics of [{sup 123}I]ADAM in SERT neurons. The effect of two psychotropics and one narcotic on the binding of [{sup 123}I]ADAM to SERT was also studied. Fluoxetine and desipramine, both are psychotropics and specific SERT ligands and decreased the affinity of [{sup 123}I]ADAM, while p-chloroamphetamine (PCA), a narcotic, destroyed most of serotonergic neurons, as well as reducing the concentration of serotonin and the number of SERT in the brain as shown by the biodistribution of [{sup 123}I]ADAM. Significant and selective accumulation of [{sup 123}I]ADAM in the areas from midbrain to brain stem in normal mice with maximum target-to-background ratio was found at 90 minutes postinjection. A rapid clearance of [{sup 131}I]ADAM at 120 minutes postinjection was found in the CA1, CA3 and ThN brain areas. In addition, the inhibition effect on binding ability of [{sup 123}I]ADAM to SERT by the psychotropics and the narcotic was found to have the order of: PCA > fluoxetine > desipramine.

  1. Regulation of ADAM12 cell-surface expression by protein kinase C epsilon

    DEFF Research Database (Denmark)

    Sundberg, Christina; Thodeti, Charles Kumar; Kveiborg, Marie

    2004-01-01

    The ADAM (a disintegrin and metalloprotease) family consists of multidomain cell-surface proteins that have a major impact on cell behavior. These transmembrane-anchored proteins are synthesized as proforms that have (from the N terminus): a prodomain; a metalloprotease-, disintegrin......-like-, cysteine-rich, epidermal growth factor-like, and transmembrane domain; and a cytoplasmic tail. The 90-kDa mature form of human ADAM12 is generated in the trans-Golgi through cleavage of the prodomain by a furin-peptidase and is stored intracellularly until translocation to the cell surface...... as a constitutively active protein. However, little is known about the regulation of ADAM12 cell-surface translocation. Here, we used human RD rhabdomyosarcoma cells, which express ADAM12 at the cell surface, in a temporal pattern. We report that protein kinase C (PKC) epsilon induces ADAM12 translocation to the cell...

    Full Text Available ural area has been the quiet main character of China’s economic development. The history of this thousand-year-old culture seems to be exempted from further comments about its role. Its importance has been strongly expressed during crisis which institutions of that great nation in XX century were shook. Agricultural sector was the key in modernization period initiated in 1980 even in the later phases. Agriculture preponderance as progress support of the nations is presented by Scottish thinker Adam Smith in his work An Inquiry into the Nature and Causes of the Wealth of Nations. The status of Chinese development in XVII y XVIII centuries has been characterized in this document as well as the natural order of progress against unnatural or retrograde order followed by the Netherlands, in that time the country that had achieved higher levels growth in Europe. Apparently, at present, China repeats its old experiences by concentrating on the path praised by Smith.

  3. Defenses and morality: Adam Smith, Sigmund Freud, and contemporary psychoanalysis.

    Science.gov (United States)

    Gabrinetti, Paul A; Özler, Sule

    2014-10-01

    In this paper we follow the development and transmission of moral learning from Adam Smith's impartial spectator to Sigmund Freud's superego and then to contemporary psychoanalysis. We argue that defenses are an integral component in the acquisition of any moral system. Elaborating on this argument, we assert that there is a progression from defensive systems that are "closed" to defensive systems that are "open," as defined in a recent work by Novick and Novick. The former system is "static, avoids reality, and is characterized by power dynamics, sadomasochism, and omnipotent defense." The latter, on the other hand, is a system that allows for "joy, creativity, spontaneity, love and it is attuned to reality." Furthermore, while Smith and Freud's systems are more one-person systems of defense, contemporary psychoanalysis has moved to more of a two-person system.

    Ankylosing tuberculosis is an infection caused by Mycobacterium tuberculosis in one or more components of the vertebrae; it is Pott disease or tuberculous spondylitis. It might become a potential cause of morbidity, including neurological deficits and permanent deformity of the spine. Management of TB Spondylitis, in general, is chemotherapy with antituberculosis drugs (ATG), immobilization, and spine surgical interventions. A retrospective study was conducted to analyze the patients of TB Spondylitis who had undergone surgery at Haji Adam Malik hospital from June 2015 to June 2017. The most common location is thoracal (10%), lumbal (3%), and thoracolumbal junction (3%). Decompression laminectomy with fusion (18%) is the most suitable option for surgical management. The majority, pre- operation ASIA scale is D (8%), and post operation is E (8%). It means that surgical plays an important role in themanagement of tuberculous spondylitis.

    Consider a complex system whose macrostate is statistically observable, but yet whose operating mechanism is an unknown black-box. In this paper we address the problem of inferring, from the system’s macrostate statistics, the system’s intrinsic force yielding the observed statistics. The inference is established via two diametrically opposite approaches which result in the very same intrinsic force: a top-down approach based on the notion of entropy, and a bottom-up approach based on the notion of Langevin dynamics. The general results established are applied to the problem of visualizing the intrinsic socioeconomic force-Adam Smith’s invisible hand-shaping the distribution of wealth in human societies. Our analysis yields quantitative econophysical representations of figurative socioeconomic forces, quantitative definitions of “poor” and “rich”, and a quantitative characterization of the “poor-get-poorer” and the “rich-get-richer” phenomena.

    2017-07-01

    Lance-Adams syndrome (LAS) is an uncommon neurological disorder characterized by the development of chronic post-hypoxic myoclonus. There are relatively few cases described following successful cardiopulmonary resuscitation. We report a patient who developed LAS 3 months after successful resuscitation. Cerebral imaging studies indicate that brain pathology in LAS patients is not uniform, suggesting that the pathophysiology of myoclonus may vary from patient to patient. Our patient adds to this etiological heterogeneity by demonstrating the unusual feature of cerebellar pathology by both cerebral magnetic resonance imaging and single-photon emission computed tomography scans. There is also heterogeneity of these patients in their response to therapy. Unlike some patients described in the literature, our patient has not responded to drug treatment. Studies of these rare patients with LAS are important as they provide insight into the pathophysiology of this condition which, it is hopefully, will facilitate the development of more effective therapy.

    2015-01-01

    Full Text Available According to the functions of parametric modeling and analysis from ADAMS, this thesis was established a parametric simulation model in order to optimize the rated output power of electric cylinders according to the real field environment. First, the variable which could affect sensitivity of the output variables was chosen by the electric cylinder’s elongation which was obtained through loop vector method. Then this thesis tried to get the optimum optimization design parameters through the simulation, and the change of rated output power affected by the change of parameters, meanwhile, made a filter and calibration of parameters which have greater influence on sensibilities. The goal of design could meet the qualification with less work load and faster speed. It is concluded that the change of the location parameters affects the rated output power.

    Sheehan, William

    2011-01-01

    As one of the most significant achievements of 19th century astronomy, the discovery of Neptune has been the subject of a vast literature. A large part of this literature--beginning with the period immediately after the optical discovery in Berlin--has been the obsession with assigning credit to the two men who attempted to calculate the planet's position (and initially this played out against the international rivalry between France and England). Le Verrier and Adams occupied much different positions in the Scientific Establishments of their respective countries; had markedly different personalities; and approached the investigation using different methods. A psychiatrist and historian of astronomy tries to provide some new contexts to the familiar story of the discovery of Neptune, and argues that the personalities of these two men played crucial roles in their approaches to the problem they set themselves and the way others reacted to their stimuli. Adams had features of high-functioning autism, while Le Verrier's domineering, obsessive, orderly personality--though it allowed him to be immensely productive--eventually led to serious difficulties with his peers (and an outright revolt). Though it took extraordinary smarts to calculate the position of Neptune, the discovery required social skills that these men lacked--and thus the process to discovery was more bumbling and adventitious than it might have been. The discovery of Neptune occurred at a moment when astronomy was changing from that of heroic individuals to team collaborations involving multiple experts, and remains an object lesson in the sociological aspects of scientific endeavor.

  14. Nuclear trafficking of the HIV-1 pre-integration complex depends on the ADAM10 intracellular domain

    Endsley, Mark A.; Somasunderam, Anoma D.; Li, Guangyu; Oezguen, Numan; Thiviyanathan, Varatharasa; Murray, James L.; Rubin, Donald H.; Hodge, Thomas W.

    2014-01-01

    Previously, we showed that ADAM10 is necessary for HIV-1 replication in primary human macrophages and immortalized cell lines. Silencing ADAM10 expression interrupted the HIV-1 life cycle prior to nuclear translocation of viral cDNA. Furthermore, our data indicated that HIV-1 replication depends on the expression of ADAM15 and γ-secretase, which proteolytically processes ADAM10. Silencing ADAM15 or γ-secretase expression inhibits HIV-1 replication between reverse transcription and nuclear entry. Here, we show that ADAM10 expression also supports replication in CD4 + T lymphocytes. The intracellular domain (ICD) of ADAM10 associates with the HIV-1 pre-integration complex (PIC) in the cytoplasm and immunoprecipitates and co-localizes with HIV-1 integrase, a key component of PIC. Taken together, our data support a model whereby ADAM15/γ-secretase processing of ADAM10 releases the ICD, which then incorporates into HIV-1 PIC to facilitate nuclear trafficking. Thus, these studies suggest ADAM10 as a novel therapeutic target for inhibiting HIV-1 prior to nuclear entry. - Highlights: • Nuclear trafficking of the HIV-1 pre-integration complex depends on ADAM10. • ADAM10 associates with HIV-1 integrase in the pre-integration complex. • HIV-1 replication depends on the expression of ADAM15 and γ-secretase. • Silencing ADAM15 or γ-secretase expression inhibits nuclear import of viral cDNA. • ADAM10 is important for HIV-1 replication in human macrophages and CD4 + T lymphocytes

    Previously, we showed that ADAM10 is necessary for HIV-1 replication in primary human macrophages and immortalized cell lines. Silencing ADAM10 expression interrupted the HIV-1 life cycle prior to nuclear translocation of viral cDNA. Furthermore, our data indicated that HIV-1 replication depends on the expression of ADAM15 and γ-secretase, which proteolytically processes ADAM10. Silencing ADAM15 or γ-secretase expression inhibits HIV-1 replication between reverse transcription and nuclear entry. Here, we show that ADAM10 expression also supports replication in CD4{sup +} T lymphocytes. The intracellular domain (ICD) of ADAM10 associates with the HIV-1 pre-integration complex (PIC) in the cytoplasm and immunoprecipitates and co-localizes with HIV-1 integrase, a key component of PIC. Taken together, our data support a model whereby ADAM15/γ-secretase processing of ADAM10 releases the ICD, which then incorporates into HIV-1 PIC to facilitate nuclear trafficking. Thus, these studies suggest ADAM10 as a novel therapeutic target for inhibiting HIV-1 prior to nuclear entry. - Highlights: • Nuclear trafficking of the HIV-1 pre-integration complex depends on ADAM10. • ADAM10 associates with HIV-1 integrase in the pre-integration complex. • HIV-1 replication depends on the expression of ADAM15 and γ-secretase. • Silencing ADAM15 or γ-secretase expression inhibits nuclear import of viral cDNA. • ADAM10 is important for HIV-1 replication in human macrophages and CD4{sup +} T lymphocytes.

    To investigate the effects of a disintegrin and metalloproteinase 28 (ADAM28) on proliferation, differentiation and apoptosis of human dental pulp stem cells (HDPSCs) and the possible mechanism. Firstly, HDPSCs were isolated and cultured in vitro and identified. ADAM28 eukaryotic expression plasmid was constructed via gene rebuilt technique and transfected into HDPSCs. Then MTT chromatometry, enzyme dynamics and flow cytometry (FCM) techniques were performed to detect the effects of ADAM28 on biological characteristics of HDPSCs. Immunocytochemical and image analysis techniques were used to determine the influence of ADAM28 on HDPSCs expressing dentin sialophosphoprotein (DSPP), bone sialoprotein (BSP) and osteopontin (OPN). Statistical significance was assessed by the Student-Newman-Keuls (SNK) test with SPSS 13.0 software package. ADAM28 eukaryotic plasmid was constructed and transfected into HDPSCs for 48 hours successfully. In ADAM28 eukaryotic plasmid group, proliferation activity and index of HDPSCs were lower than those of pcDNA3.1(+) group and untransfected group significantly.Alkaline phosphatase (ALP) secretion level and percentage of apoptotic cells went up remarkly. Significant difference was detected between eukaryotic plasmid group and other groups (P<0.05). The expression level of DSPP in HDPSCs elevated significantly (P<0.05). ADAM28 could inhibit HDPSCs proliferation, promote ALP secretion activity and DSPP expression in HDPSCs and induce HDPSCs apoptosis significantly.

    To evaluate the potential of maternal serum using a disintegrin and metalloprotease 12 (ADAM12) as a marker for Trisomy 21 in Chinese pregnant women. Serum samples were collected and stored from women having a viable singleton pregnancy undergoing first trimester screening for Trisomy 21 between 2006 and 2007. Serum concentration of ADAM12 was measured using an automated time-solved immuno-fluorometric assay from 608 stored serum samples (601 Euploidy and 7 Trisomy 21). Regression analysis was used to determine the expected median in Euploidy pregnancies after adjusting for pregnancy characteristics. The level of ADAM12 MoM was compared between Trisomy 21 and Euploidy pregnancies. Expected median levels in Chinese were compared to that published for Caucasians and Afro-Caribbeans. In Euploidy pregnancies, the concentration of ADAM12 increased with CRL and decreased with maternal weight. The expected median level of ADAM12 in Chinese was significantly lower than Caucasian and Afro-Caribbeans (F=14.2, ppregnancy-associated plasma protein A MoMs (r=0.46; ppregnancies was not significantly different from that in Euploidy pregnancies (z=0.18; p=0.88). ADAM12 concentrations in Chinese are lower than those of Caucasians and Afro-Carribeans; that ADAM12 MoM levels in Euploidy and Trisomy 21 pregnancies were not statistically different.

    Serotonin transport abnormalities are implicated in neuropsychiatric disorders. [ 123 I]ADAM ([ 123 I]-2-([2-({dimethylamino}methyl)phenyl]thio)-5-iodophenylamine) is a novel radiotracer that targets serotonin transporters. We assessed the toxicity of [ 123 I]ADAM (18.5 MBq) administered in early- and late-phases (8 and 14 day postfertilization, respectively) of pregnancy. The mortality, clinical status, and gross necropsy were measured in pregnant rats, and the fertility index was measured in rat offspring (weight, clinical observations). We found no dosing-related clinical signs. In conclusion, [ 123 I]ADAM was not toxic in an animal pregnancy model.

    Thermoluminescence has become an established dating method for ceramics and more recently for bricks. Based on the experiences of the work carried out since the late 1970's at the Rathgen-Forschungslabor in Berlin on the dating of bricks from historic architecture, and after evaluating all commercially available and some individually built automated and semi-automated TL-readers, a specially adapted machine for the fine grain dating of bricks was constructed in an interdisciplinary research project, undertaken by a team recruited from three faculties of the Czech Technical University in Prague. The result is the automated TL-reader ADAM-1 (Automated Dating Apparatus for Monuments) for the dating of historic architecture. Both the specific adaptation of the technique and the necessary optimal automation have influenced the design of this TL-reader. The principle advantage of brick as opposed to ceramic TL-dating emerges from the possibility of being able to obtain both a large number of samples and an above average quantity of datable material from each sample. This, together with the specific physical and chemical conditions in a brick wall, allowed a rethinking of the traditional error calculation and thus lower error margins as those obtained when dating ceramic shards. The TL-reader must therefore be able to measure and evaluate automatically numerous samples. The annular sample holder of ADAM-1 has 60 sample positions, which allow the irradiation and evaluation of samples taken from two locations. The thirty samples from one sampling point are divided into subgroups, which are processed in various ways. Three samples serve for a rough estimate of the TL sensitivity of the brick material. Nine samples are used for the measurement of 'natural TL' of the material. A further nine samples are used for testing the sensitivity of the material to beta radiation. The last nine samples serve for the testing of the sensitivity to alpha radiation. To determine the

    Full Text Available The difference between Adam and Eve’s lament on leaving Paradise in Milton’s Paradise Lost is striking in its contrastive content and depth. This paper analyzes the difference that exists between the feelings and spiritual attitudes that Adam and Eve express on the occasion when they are informed by the angel Michael that they have to abandon the Garden of Eden. It is a comparison of their lament in order to understand the contrast of the two attitudes that Milton wove in the tapestry that Paradise Lost is. The paper also explores male and female roles in Paradise Lost and concludes that Adam and Eve are equal yet different, that difference being the cause of their contrastive ways of expressing their sorrow. Adam and Eve manifest two contrastive worldviews in opposition, one spiritual (heavenly, and the other material (earthly.

    Introduction: Single photon emission computed tomography (SPECT) imaging of the serotonin transporter (SERT) in the brain is a useful tool for examining normal physiological functions and disease states involving the serotonergic system. The goal of this study was to develop an improved SPECT radiotracer with faster kinetics than the current leading SPECT tracer, [{sup 123}I]ADAM, for selective SERT imaging. Methods: The in vitro binding affinities of (2-(2'-((dimethylamino)methyl)-4'-iodophenylthio)benzenamine) (FlipADAM) (1c), were determined using Hampshire pig kidney cells stably overexpressing the serotonin, norepinephrine (NET) or dopamine transporter (DAT). Localization of [{sup 125}I]FlipADAM (1c) was evaluated through biodistribution and autoradiography in male Sprague Dawley rats, and the specificity of binding was assessed by injecting selective SERT or NET inhibitors prior to [{sup 125}I]FlipADAM (1c). Results: FlipADAM (1c) displayed a high binding affinity for SERT (K{sub i}=1.0 nM) and good selectivity over NET and DAT binding (43-fold and 257-fold, respectively). [{sup 125}I]FlipADAM (1c) successfully penetrated the blood brain barrier, as evidenced by the brain uptake at 2 min (1.75% dose/g). [{sup 125}I]FlipADAM(1c) also had a good target to non-target (hypothalamus/cerebellum) ratio of 3.35 at 60 min post-injection. In autoradiography studies, [{sup 125}I]FlipADAM (1c) showed selective localization in SERT-rich brain regions such as the thalamic nuclei, amygdala, dorsal raphe nuclei and other areas. Conclusion: [{sup 125}I]FlipADAM (1c) exhibited faster clearance from the brain and time to binding equilibrium when compared to [{sup 125}I]2-(2'-((dimethylamino)methyl)-phenylthio)-5-iodophenylamine [{sup 125}I]ADAM (1b) and a higher target to non-target ratio when compared to [{sup 125}I]5-iodo-2-(2'-((dimethylamino)methyl)-phenylthio)benzyl alcohol [{sup 125}I]IDAM (1a). Therefore, [{sup 123}I]FlipADAM (1c) may be an improved

    The birth of Adam Nash, following IVF and then preimplantation genetic diagnosis (PGD) on the resulting 15 embryos to find which would be a potential bone marrow match for his older sibling, suffering from Fanconi's anaemia, is the first reported case of genetic selection of an embryo to save the life of an existing person. The case has stirred debates worldwide over the appropriateness and implications of using the technique for this and related purposes. Legally, it is suggested that embryos are indeed entitled to special respect because of their potential for life, but certain principles must not be overlooked, and the Nash case was wholly within acceptable legal principles. The legal perspective offered here concludes: (i) while embryos are entitled to certain protections, the mere fact that they are extracorporeal raises the danger that the rights and protections assigned to them will be wrongly elevated over the legally protected procreation rights of the adults who create them; (ii) divorce litigation involving "custody" of embryos is not a direct parallel and legal analogies must be distinguished; (iii) the status of embryos must be carefully defined; and (iv) a national or international, multi-disciplinary body should be created to grapple with the developing issues and uses that are sure to follow.

    I The Theory of Moral Sentiments giver Adam Smith en fremstilling af, hvordan mennesket i sam­fundslivet udvikler moralske fornemmelser og af den betydning, disse har for menneskers følelses- og handlingsliv. Her er synssansen afgørende, idet den sætter mennesket i stand til rumligt lokaliser......­bart at betragte andre menneskers opførsel såvel som andre menneskers reaktioner på ens egen opførsel.

Ikke desto mindre påkalder...... han jævnligt bl.a. naturen som en metafysisk entitet.

    2015-08-01

    Full Text Available In his Histories 8:118, Herodotus tells the dramatic story of Xerxes’ return to Asia from Greece by sea. The overcrowded ship was caught in a storm, and the captain advised the king to get rid of most of the passengers. Xerxes called on the Persians to prove their loyalty to the king, and they showed their obeisance by leaping into the sea. After his return, Xerxes awarded the captain of the ship with a golden crown for saving the king’s life—and cut off his head for causing the deaths of so many Persians. In the play Adam and Eve, Bulgakov depicts the outbreak of war between the Soviet Union and the Western world. Nearly everyone in Leningrad dies from a gas attack. But Efrosimov, a chemistry professor and a man of genius, has managed to save the lives of the other characters in the play, the Soviet fighter pilot Daragan included. Nevertheless, Daragan hates Efrosimov for his efforts to prevent the war and then to stop it. The fighter pilot imagines for the professor both an award for his merits and subsequent capital punishment for his alleged crime. In this article, I suggest that Bulgakov has borrowed the motif of award and execution from Herodotus.

    2012-03-01

    Full Text Available At a time of not only empirical crisis, but also a philosophical crisis of the underpinning ideologies of the liberal capitalist economic system, there is an increasing tendency to dogmatize the work of classical thinkers, using selective readings of their work as the basis for support or critique of the status quo. Few are as subject to selective reading as the so-called father of modern economics, Adam Smith. This paper seeks to reflect on Smith's thought on two central aspects of the modern crisis: the nature of the limited liability corporation (whose profit motive is increasingly being challenged on a number of grounds and the role of the individual in a market economy (amid accusations from across the political and philosophical spectrum about the increasing isolation, individualization, and neo-liberalization of the self. These subjects are not as different as they might seem as they both relate to Smith's conception of the nature role of the individual actor - homo oeconomicus - not only in a market in and of itself, but in a market that Smith saw as a social creation and a part of a human community.

    ADAMS/WT is an wind-turbine-specific shell for the general-purpose mechanical system simulation package ADAMS5. It was developed under the guidance of the National Renewable Energy Laboratory to give engineers and analysts in the wind turbine community access to the analytical power of ADAMS, without having to become expert in its particular technology. The 1.4 version of ADAMS/WT is the most recent upgrade to the package, incorporating the most up-to-date version of the AeroDyn aerodynamic forcing subroutines from the University of Utah. It is also the first version to be made available on the Windows/NT platform. In version 1.4, ADAMS/WT has been significantly improved throughout and runs much faster. Automatic generation of standardized output has been added. The documentation has been extensively augmented with more detailed descriptions, more figures and more examples. ADAMS/WT remains the most powerful analytical tool available for horizontal-axis wind turbine development. 10 figs.

    2009-09-01

    Full Text Available Abstract Background The transforming growth factor beta is known to have pleiotropic effects, including differentiation, proliferation and apoptosis. However the underlying mechanisms remain poorly understood. The regulation and effect of TGF-β signaling is complex and highly depends on specific protein context. In liver, we have recently showed that the disintegrin and metalloproteinase ADAM12 interacts with TGF-β receptors and modulates their trafficking among membranes, a crucial point in TGF-β signaling and development of fibrosis. The present study aims to better understand how ADAM12 impacts on TGF-β receptors trafficking and TGF-β signaling. Findings We extracted qualitative biological observations from experimental data and defined a family of models producing a behavior compatible with the presence of ADAM12. We computationally explored the properties of this family of models which allowed us to make novel predictions. We predict that ADAM12 increases TGF-β receptors internalization rate between the cell surface and the endosomal membrane. It also appears that ADAM12 modifies TGF-β signaling shape favoring a permanent response by removing the transient component observed under physiological conditions. Conclusion In this work, confronting differential models with qualitative biological observations, we obtained predictions giving new insights into the role of ADAM12 in TGF-β signaling and hepatic fibrosis process.

Snake venom metalloproteinases (SVMPs are major components in most viper venoms. SVMPs are primarily responsible for hemorrhagic activity and may also interfere with the hemostatic system in envenomed animals. SVMPs are phylogenetically most closely related to ADAMs and, together with ADAMs and related ADAM with thrombospondin motifs (ADAMTS family proteinases, constitute adamalysins/reprolysins or the M12B clan (MEROPS database of metalloproteinases. Although the catalytic domain structure is topologically similar to that of other metalloproteinases such as matrix metalloproteinases, the M12B proteinases have a modular structure with multiple non-catalytic ancillary domains that are not found in other proteinases. Notably, crystallographic studies revealed that, in addition to the conserved metalloproteinase domain, M12B members share a hallmark cysteine-rich domain designated as the “ADAM_CR” domain. Despite their name, ADAMTSs lack disintegrin-like structures and instead comprise two ADAM_CR domains. This review highlights the current state of our knowledge on the three-dimensional structures of M12B proteinases, focusing on their unique domains that may collaboratively participate in directing these proteinases to specific substrates.

  3. An Adamic incarnational Christological framework as a theological approach for African contextual ministry

    Directory of Open Access Journals (Sweden)

    Magezi, Vhumani

    2016-12-01

    Full Text Available Many African Christian thinkers and writers are responding to the foreignness of Christ in African Christianity by treating Christ under the traditional African ancestral category. However, it is our contention that the designation of the ancestral category to Christ has a tendency of diminishing the actuality of Christ as God incarnate and encouraging syncretism in African Christianity. Given this, this paper proposes and formulates an Adamic incarnational Christological model as an alternative response to the foreignness of Christ in African Christianity. In employing the anhypostastic and enhypostastic principles, we demonstrate that Jesus Christ is not a foreigner to African Christians, since the human nature he assumed in the incarnation is a general human nature which embraces all humankind. In establishing the Adam-Christ relationship in Romans 5:12-21 and 1 Corinthians 15:21-22, we advance Adam as a biblical-theological category in enhancing the relevance of Christ to Africans. It is from this perspective that our Adamic incarnational Christological model proposes that in the incarnation, God in Christ fully identified with all mankind as the New Adam, acting from the ontological depth of his divine-human existence to save African Christians from sin and all its consequences, including death and opposing spiritual forces. Thus, our own model underscores the relevance of Christ to African Christians by emphasizing Christs complete solidarity with all humanity as the New Adam.

    Full Text Available Sexual abuse is defined as use of child or adolescent by the adults for satisfying of sexual urges and needs with forcing, threatening or tricking. Sexual abuse can be in the form of sexual abuse without touch, sexual touch, interfemoral intercourse, sexual penetration, and sexual exploitation. The prevalence of sexual abuse is reported as 10-40%. It is seen in female four times more than in males. Abusers are frequently male, only 5-15% of them are female. The abuse by females is usually towards male child. Thirty-fifty percent of abuse cases among child and adolescent are outside the family including strangers or familiar person. Some features of abusers are introvert personality, pedophilic and antisocial personality. Most of the abusers have a history of sexual abuse or aggression during childhood. Sexual intercourse between two people who are not allowed to marry by law is called as incest. Family pattern of incest is defined globally as disorganized and dysfunctional. The most commonly reported familial pattern is rigid and patriarchal family pattern with a harsh father using force quite frequently. The clinical features and impacts of the sexual abuse on the child varies according to the relation between abusers and the child, form of abuse, duration of abuse, presence of physical assault, developmental phase, child age and psychological development before the abuse. Sexual abuse history may result in psychiatric disorders including anxiety, depression, substance dependence, suicide act, borderline personality disorder, posttraumatic stress disorder. Abuse negatively affects interpersonal relationships and self esteem of abused individuals. Several studies reported close association between risky sexual behaviors in adulthood and a history of of sexual abuse during childhood. Four traumatic dynamics including traumatic sexuality with abuse, feeling of betrayal, weakness, and stigmatization exist in childhood abuse. Trauma can cause

  5. Spiro K. Antiochos Receives 2013 John Adam Fleming Medal: Citation

    Klimchuk, James A.

    2014-01-01

    The John Adam Fleming Medal is awarded for "original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, space physics, and related sciences." Originality and technical leadership are exactly the characteristics that distinguish the research of Spiro K. Antiochos. Spiro possesses a truly unique combination of physical insight, creativity, and mastery of the concepts and mathematical and numerical tools of space physics. These talents have allowed him to develop completely original theories for major observational problems and to test and refine those theories using sophisticated numerical simulation codes that he himself helped to develop. Spiro's physical insight is especially impressive. He has an uncanny ability to identify the fundamental aspects of complex problems and to see physical connections where others do not. This can sometimes involve ideas that may initially seem counterintuitive to those with less creativity. Many of Spiro's revolutionary advances have opened up whole new areas of study and shaped the course of space physics. Examples include the breakout model for coronal mass ejections (CMEs), the S-web model for the slow solar wind, and the thermal nonequilibrium model for solar prominences. The breakout model is of special significance to AGU as it strives to promote science for the betterment of humanity. CMEs are enormous explosions on the Sun that can have major "space weather" impacts here on Earth. They affect technologies ranging from communication and navigation systems to electrical power grids. Breakout is the leading theory for why CMEs occur and may one day be the foundation for more accurate space weather forecasting.

    Full text: A disintegrin and metalloproteinase (ADAM) protease is involved in proteolytic ectodomain shedding of several membrane-associated proteins and modulation of key cell signaling pathways in the tumor microenvironment. In this study, we examined the effect of over-expressing the full length human ADAM17 in membrane and secreted proteins. To this end, we constructed a stable Flp-In T-RExHEK293 cells expressing ADAM17 by tetracycline induction. These cells were grown in Dulbeccos modified Eagles medium containing light lysine, arginine or heavy, L-Arg-13C615N4 and L-Lys -13C615N2 (SILAC: stable isotope labeling with amino acid in cell culture) media and they were treated with an ADAM17 activator, phorbolester (PMA). Controls such as Flp-In T-RExHEK293 cell without PMA treatment and without ADAM17 cloned were cultivated in light medium. The ADAM17 overexpression was induced with tetracycline 500 ng/ml for 24 hours. Cells in a heavy condition were treated with PMA 50 ng/ml for 1 hour and vehicle DMSO was used as control in a light cell condition. The extracellular media were collected, concentrated and used to evaluate the secretome and a cell surface biotinylation-based approach was used to capture cell surface-associated proteins. The biotinylated proteins were eluted with dithiothreitol, alkylated with iodoacetamide and then digested with trypsin. The resulting peptides were subjected to LC-MS/MS analysis on an ETD enabled Orbitrap Velos instrument. The results showed different proteins up or down regulated in membrane and secretome analysis which might represent potential molecules involved in signaling or ADAM17 regulation events. (author)

  15. Measuring abusive behaviors: is economic abuse a unique form of abuse?

    Science.gov (United States)

    2013-11-01

    Recent attention has been given by researchers to exploring economic abuse strategies used by abusers. However, little research has been conducted to understanding how to conceptualize economic abuse in relation to other forms of abuse. This article examines the factor structure of abusive items from the Scale of Economic Abuse--12 and the Abusive Behavior Inventory through confirmatory factor analyses using data collected with 457 female survivors of abuse. The findings provide evidence for conceptualizing economic abuse as a unique form of abuse moderately correlated with psychological, physical, and sexual forms of abuse.

    A disintegrin and metalloprotease (ADAM)10 has been implicated in the progression of various solid tumours. Little is known, however, about its role in hepatocellular carcinoma (HCC). The aim of the present study was to evaluate the protein and transcript level expression of ADAM10 in HCC patients. Samples of HCC and adjacent noncancerous liver tissue were taken during liver resection surgery. Immunostaining was used to measure ADAM10 protein expression levels and quantitative reverse- transcription polymerase chain reaction was used to measure ADAM10 mRNA expression levels. Levels of ADAM10 were compared, and a survival analysis undertaken. In total, 98 HCC patient samples were studied. There were significant associations between protein levels of ADAM10 and tumour grade, amount of tumour differentiation, tumour size and the presence of metastasis. Furthermore, ADAM10 protein expression was significantly associated with shortened patient survival. ADAM10 is strongly expressed in a large proportion of HCC cases, which is in agreement with findings in other tumour entities. Expression of ADAM10 may serve as a useful molecular marker for HCC. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  19. Indian Policy of John Adams Administration: the Contours of the Political Course

    2016-06-01

    Full Text Available The article considers the policy of John Adams administration toward the Native Americans in 1797-1801. This subject was not investigated by Russian scholars. Foreign scholars researched the Indian policy of the second president of the United States only in general terms. They paid attention to the views of John Adams towards the Natives and to the common principals of such policy. In fact the details of the policy have to be explored. The lack of attention by the scholars towards John Adams’ Indian policy can be explained by the fact that the period of 1797-1801 was not rich in significant events in Indian-White relations. There were no great conflicts between the two nations. It seems that John Adams was not an enthusiastic reformer. However the problems of the frontier existed and they could be solved. The second president of the USA did his work and tried to reduce the negative influence of foreign agents on the Native Americans. In this task he had to use the experience of George Washington, who was the real enthusiast in implementing the Indian policy. The other issue that had to be solved dealt with the Indian lands. John Adams administration did the best to overcome all difficulties with minimal losses. The author tries to acquit John Adams and to show the reasons why his Indian policy was not so bright as George Washington’s or Thomas Jefferson’s ones.

  20. Identification and Function of a Novel Candidate Gene for Asthma:ADAM 33

    Directory of Open Access Journals (Sweden)

    John W. Holloway

    2005-01-01

    Full Text Available Asthma is a complex disorder of inflammation and remodelling largely restricted to the conducting airways. It is a disorder where there are major genetics and environmental factors that interact together to initiate and propagate the disease into a chronic relapsing disorder. Until recently the genetic factors involved in disease pathogenesis have been restricted to variants in known molecules involved in the inflammatory or remodelling pathways. In this review evidence is presented for a new susceptibility gene for asthma, ADAM 33, that was identified by positional cloning. It is suggested that ADAM 33 plays a key role in predisposing to reduced lung function and bronchial hyperresponsiveness characteristic of asthma. Through an understanding of the disease-related SNPs(in ADAM 33it may be possible, not only to identify a gene based diagnostic test, but also to focus attention on developing a new treatment that reverses remodelling changes.

    The increased expression of the Disintegrin and Metalloprotease ADAM12 has been associated with human cancers, however its role remain unclear. We have previously reported that ADAM12 expression is induced by the transforming growth factor, TGF-β and promotes TGF-β-dependent signaling through interaction with the type II receptor of TGF-β. Here we explore the implication of ADAM12 in TGF-β-mediated epithelial to mesenchymal transition (EMT), a key process in cancer progression. We show that ADAM12 expression is correlated with EMT markers in human breast cancer cell lines and biopsies. Using a non-malignant breast epithelial cell line (MCF10A), we demonstrate that TGF-β-induced EMT increases expression of the membrane-anchored ADAM12L long form. Importantly, ADAM12L overexpression in MCF10A is sufficient to induce loss of cell-cell contact, reorganization of actin cytoskeleton, up-regulation of EMT markers and chemoresistance. These effects are independent of the proteolytic activity but require the cytoplasmic tail and are specific of ADAM12L since overexpression of ADAM12S failed to induce similar changes. We further demonstrate that ADAM12L-dependent EMT is associated with increased phosphorylation of Smad3, Akt and ERK proteins. Conversely, inhibition of TGF-β receptors or ERK activities reverses ADAM12L-induced mesenchymal phenotype. Together our data demonstrate that ADAM12L is associated with EMT and contributes to TGF-β-dependent EMT by favoring both Smad-dependent and Smad-independent pathways. PMID:26407179

    Equine laminitis is a debilitating disease affecting the digital laminae that suspend the distal phalanx within the hoof. While the clinical progression of the disease has been well documented, the molecular events associated with its pathogenesis remain largely unknown. Using real time quantitative PCR (RT-qPCR), we have investigated the expression of genes coding for proteins containing a Disintegrin and Metalloprotease domain (ADAM), as well as genes encoding the natural inhibitors of these enzymes (tissue inhibitor of metalloprotease; TIMP) in horses with naturally-acquired (acute, chronic and aggravated chronic clinical cases) or experimentally-induced (black walnut extract (BWE) and starch gruel models) laminitis. Changes in expression of these enzymes and regulators may underlie the pathologic remodeling of lamellar tissue in laminitis. Genes encoding ADAMs involved in inflammation (ADAM-10 and ADAM-17), as well as those implicated in arthritis (ADAMTS-1, ADAMTS-4 and ADAMTS-5) were cloned, and the sequences used to generate specific oligonucleotide primers for the RT-qPCR experiments. Our results show that genes encoding ADAM-10 and ADAM-17 were not induced in most laminitic animals, whereas ADAMTS-4 gene expression was strongly upregulated in nearly all horses with experimentally-induced and naturally-acquired laminitis. The expression of matrix metalloproteases (MMP)-9 and ADAMTS-5 was also increased in many of the laminitic horses. In addition, TIMP-2 gene expression was decreased in most laminitic horses, whereas expression of genes encoding other TIMPs, namely TIMP-1 and TIMP-3, was randomly increased or decreased in the various models. We conclude that increased expression of lamellar ADAMTS-4 is a common feature of laminitis consistent with a central role of the gene product in the pathophysiology of the disease.

    Full Text Available Through the present paper, the author presents the results of the dynamic analysis with MSC ADAMS of the mechanism with a crimping device with 12 tightening cams, designed and used in the technological process of assembly of the indigenous electrical detonators. In this sense, the mechanism with multiple cams is considered a mechanical system and is treated as an assembly of rigid bodies connected by mechanical connections and elastic elements. For shaping and simulation of the mechanism with multiple cams using ADAMS program, the author got through the following stages: construction of the pattern, its testing and simulation, validation, finishing, parametrization, optimization of the pattern.

    Adam Zamenhof was greatly influenced by his father, Ludwik Zamenhof, who designed the international language Esperanto. Like his father, he became an ophthalmologist and joined the Esperanto movement. He published in the field of ophthalmology and was soon chosen as head of an ophthalmology department. He subsequently became Chief of the Orthodox Jewish Hospital at Czystem in Warsaw. He was active in the leadership of the Bialystok-Warsaw Chamber of Medical Doctors. He perished in the Nazi Holocaust (Shoah) but all Zamenhof's ideals that Adam served as a doctor and social activist remain still alive.

    A disintegrin and metalloproteinase 33 (ADAM33) has been identified as a susceptibility gene for asthma, but details of the causality are not fully understood. We hypothesize that soluble ADAM33 (sADAM33) overexpression can alter the mechanical behaviors of airway smooth muscle cells (ASMCs) via regulation of the cell's contractile phenotype, and thus contributes to airway hyperresponsiveness (AHR) in asthma. To test this hypothesis, we either overexpressed or knocked down the sADAM33 in rat ASMCs by transfecting the cells with sADAM33 coding sequence or a small interfering RNA (siRNA) that specifically targets the ADAM33 disintegrin domain, and subsequently assessed the cells for stiffness, contractility and traction force, together with the expression level of contractile and proliferative phenotype markers. We also investigated whether these changes were dependent on Rho/ROCK pathway by culturing the ASMCs either in the absence or presence of ROCK inhibitor (H1152). The results showed that the ASMCs with sADAM33 overexpression were stiffer and more contractile, generated greater traction force, exhibited increased expression levels of contractile phenotype markers and markedly enhanced Rho activation. Furthermore these changes were largely attenuated when the cells were cultured in the presence of H-1152. However, the knock-down of ADAM33 seemed insufficient to influence majority of the mechanical behaviors of the ASMCs. Taken together, we demonstrated that sADAM33 overexpression altered the mechanical behaviors of ASMCs in vitro, which was most likely by promoting a hypercontractile phenotype transition of ASMCs through Rho/ROCK pathway. This revelation may establish the previously missing link between ADAM33 expression and AHR, and also provide useful insight for targeting sADAM33 in asthma prevention and therapy. - Highlights: • sADAM33 overexpression enhances the stiffness, traction force and contractility of ASMCs. • sADAM33 overexpression promotes

  17. Sexual abuse of boys.

    2005-01-01

    Sexual abuse in childhood can disable self-esteem, self-concept, relationships, and ability to trust. It can also leave psychological trauma that compromises a boy's confidence in adults. While some boys who willingly participate may adjust to sexual abuse, many others face complications, such as reduced quality of life, impaired social relationships, less than optimal daily functioning, and self-destructive behavior. These problems can respond to treatment if detected. In this paper, we examine the prevalence, characteristics, psychological consequences, treatment, and coping patterns of boys who have been sexually abused and their failure to disclose abuse unless asked during a therapeutic encounter. Nurses have a responsibility to detect the clues to sexual abuse, diagnose the psychological consequences, and advocate for protection and treatment. Computerized literature search of the Medline and PsychInfo literature and books on sexual abuse of boys. Psychological responses to abuse such as anxiety, denial, self-hypnosis, dissociation, and self-mutilation are common. Coping strategies may include being the angry avenger, the passive victim, rescuer, daredevil, or conformist. Sexual abuse may precipitate runaway behavior, chronic use of sick days, poor school or job performance, costly medical, emergency and or mental health visits. In worst cases, the boy may decide that life is not worth living and plan suicide. The nurse has a key role to play in screening, assessing, and treating sexual abuse children.

  18. Alternative drugs of abuse.

    2014-02-01

    The incidence of drug abuse with alternative agents is increasing. The term "alternative drugs of abuse" is a catch-all term for abused chemicals that do not fit into one of the classic categories of drugs of abuse. The most common age group abusing these agents range from 17 to 25 years old and are often associated with group settings. Due to their diverse pharmacological nature, legislative efforts to classify these chemicals as a schedule I drug have lagged behind the development of new alternative agents. The potential reason for abuse of these agents is their hallucinogenic, dissociative, stimulant, anti-muscarinic, or sedative properties. Some of these drugs are easily obtainable such as Datura stramonium (Jimson Weed) or Lophophora williamsii (Peyote) because they are natural plants indigenous to certain regions. The diverse pharmacology and clinical effects of these agents are so broad that they do not produce a universal constellation of signs and symptoms. Detailed physical exams are essential for identifying clues leading one to suspect an alternative drug of abuse. Testing for the presence of these agents is often limited, and even when available, the results do not return in a timely fashion. Intoxications from these agents pose unique challenges for health care providers. Physician knowledge of the physiological effects of these alternative agents and the local patterns of drug of abuse are important for the accurate diagnosis and optimal care of poisoned patients. This review summarizes the current knowledge of alternative drugs of abuse and highlights their clinical presentations.

    ADAM10, a member of a disintegrin and metalloprotease family, is an alpha-secretase capable of anti-amyloidogenic proteolysis of the amyloid precursor protein. Here, we present evidence for genetic association of ADAM10 with Alzheimer's disease (AD) as well as two rare potentially disease-associated non-synonymous mutations, Q170H and R181G, in the ADAM10 prodomain. These mutations were found in 11 of 16 affected individuals (average onset age 69.5 years) from seven late-onset AD families. Each mutation was also found in one unaffected subject implying incomplete penetrance. Functionally, both mutations significantly attenuated alpha-secretase activity of ADAM10 (>70% decrease), and elevated Abeta levels (1.5-3.5-fold) in cell-based studies. In summary, we provide the first evidence of ADAM10 as a candidate AD susceptibility gene, and report two potentially pathogenic mutations with incomplete penetrance for late-onset familial AD.

    of differentiation. Using the yeast two-hybrid screen, we found that the muscle-specific alpha-actinin-2 strongly binds to the cytoplasmic tail of ADAM12. In vitro binding assays with GST fusion proteins confirmed the specific interaction. The major binding site for alpha-actinin-2 was mapped to a short sequence......ADAM12 belongs to the transmembrane metalloprotease ADAM ("a disintegrin and metalloprotease") family. ADAM12 has been implicated in muscle cell differentiation and fusion, but its precise function remains unknown. Here, we show that ADAM12 is dramatically up-regulated in regenerated, newly formed...... in a dominant negative fashion by inhibiting fusion of C2C12 cells, whereas expression of a cytosolic ADAM12 lacking the major alpha-actinin-2 binding site had no effect on cell fusion. Our results suggest that interaction of ADAM12 with alpha-actinin-2 is important for ADAM12 function....

    Assisted Living (AL) currently represents one of the most numerous institutional care settings for elders. Very little information exists on abuse in AL. Descriptive information on elder abuse reported by nurse aides working in AL is presented from a survey sent to nurse aides. The questionnaire had items addressing verbal, physical, psychological, caregiving, medication, material, and sexual abuse. The responses to the questions included in the verbal abuse, physical abuse, psychological abuse, caregiving abuse, medication abuse, and material exploitation abuse sections (28 questions) show that suspected abuse is not uncommon. We could not objectively verify the cases of abuse described in the survey, still, they give a first indication that staff abuse may occur in AL. This may be significant given the large number of ALs in the United States and may influence the health, quality of life, and safety of many residents.

    Atherosclerosis disease is a leading cause for mortality and morbidity. The narrowing/rupture of a vulnerable atherosclerotic plaque is accountable for acute cardiovascular events. However, despite of an intensive research, a reliable clinical method which may disclose a vulnerable patient is still unavailable. We tested the association of ADAM17 (A Disintegrin and Metallo Protease Domain 17) circulating substrates (sICAM-1, sVCAM-1, sIL6R and sTNFR1) with a second major cardiovascular events [MACEs] (cardiovascular death, peripheral artery surgeries, non-fatal myocardial infarction and non-fatal stroke) in 298 patients belonging to the Vascular Diabetes (AVD) study. To evaluate ADAM17 activity we create ADAM17 score through a RECPAM model. Finally we tested the discrimination ability and the reclassification of clinical models. At follow-up (mean 47 months, range 1-118 months), 55 MACEs occurred (14 nonfatal MI, 14 nonfatal strokes, 17 peripheral artery procedures and 10 cardiovascular deaths) (incidence = 7.8% person-years). An increased risk for incident events was observed among the high ADAM17 score individuals both in univariable (HR 19.20, 95% CI 15.82-63.36, p atherosclerosis. Copyright © 2015 Elsevier Ireland Ltd.

  8. Pastoral care and healing in Africa: Towards an Adamic Christological practical theology imagination for pastoral healing

    Directory of Open Access Journals (Sweden)

    Vhumani Magezi

    2016-11-01

    Full Text Available This article argues that the challenge and need for relevant ministry models is critical for effective Christian ministry and pastoral ministry as practical life ministry. It establishes an Adamic Christological model as a paradigm that provides a practical effective ministerial approach in Africa, particularly within the context of pastoral care and healing. This framework reveals Christ’s complete identification with African Christians in their contextual sufferings as the New Adam without compromising authentic gospel reality. In employing the Adamic Christological framework as the anchor for African pastoral and healing ministry, a model for African Christians’ daily response to their various contextual sufferings is constructed. This responsive model bridges the gap between the ascension of Christ and the interim period of Christianity by instituting God’s ongoing personal presence in believers’ suffering through the Holy Spirit (pneumatology as an encouraging and comforting reality that should enable Christians to cope in their suffering. It is argued that this Adamic Christological framework provides a practical theological model that contributes to healing and hope in pastoral care through practical knowing that impacts and imparts meaning in life.

    A peer counseling program was developed as a method for preventing drug and alcohol abuse among high school juniors and seniors. The program was implemented and the results were monitored to evaluate the impact of the program on the students. An analysis of the data showed that the students were able to learn and utilize peer counseling skills but that the prevention of drug abuse could not be documented in this study. Subjective reports, however, were found to support the effects of the program.

    The misuse of 3,4-methylenedioxymethamphetamine (MDMA) has drawn a growing concern worldwide for its psychophysiological impacts on humans. MDMA abusers are often accompanied by long-term serotonergic neurotoxicity, which is associated with reduced density of cerebral serotonin transporters (SERT) and depressive disorders. Resveratrol (RSV) is a natural polyphenolic phytoalexin that has been known for its antidepressant and neuroprotective effects. However, biological targets of RSV as well as its neuroprotective effects against MDMA remained largely unknown. In this study, we examined binding potency of RSV and MDMA to SERT using small-animal positron emission tomography (PET) with the SERT radioligand, N,N-dimethyl-2-(2-amino-4-[(18)F]fluorophenylthio)benzylamine (4-[(18)F]-ADAM) and investigated the protection of RSV against the acute and long-term adverse effects of MDMA. We found that RSV exhibit binding potentials to SERT in vivo in a dose-dependent manner with variation among brain regions. When the MDMA-treated rats (10mg/kg, s.c.) were co-injected with RSV (20mg/kg, i.p.) twice daily for 4 consecutive days, MDMA-induced acute elevation in plasma corticosterone was significantly reduced. Further, 4-[(18)F]-ADAM PET imaging revealed that RSV protected against the MDMA-induced decrease in SERT availability in the midbrain and the thalamus 2 weeks following the co-treatment. The PET data were comparable to the observation from the forced swim test that RSV sufficiently ameliorated the depressive-like behaviors of the MDMA-treated rats. Together, these findings suggest that RSV is a potential antidepressant and may confer protection against neurobiological and behavioral changes induced by MDMA.

    NASA's Digital Astronaut Project (DAP) implements well-vetted computational models to predict and assess spaceflight health and performance risks, and enhance countermeasure development. DAP provides expertise and computation tools to its research customers for model development, integration, or analysis. DAP is currently supporting the NASA Exercise Physiology and Countermeasures (ExPC) project by integrating their biomechanical models of specific exercise movements with dynamic models of the devices on which the exercises were performed. This presentation focuses on the development of a high fidelity dynamic module of the Advanced Resistive Exercise Device (ARED) on board the ISS. The ARED module, illustrated in the figure below, was developed using the Adams (MSC Santa Ana, California) simulation package. The Adams package provides the capabilities to perform multi rigid body, flexible body, and mixed dynamic analyses of complex mechanisms. These capabilities were applied to accurately simulate: Inertial and mass properties of the device such as the vibration isolation system (VIS) effects and other ARED components, Non-linear joint friction effects, The gas law dynamics of the vacuum cylinders and VIS components using custom written differential state equations, The ARED flywheel dynamics, including torque limiting clutch. Design data from the JSC ARED Engineering team was utilized in developing the model. This included solid modeling geometry files, component/system specifications, engineering reports and available data sets. The Adams ARED module is importable into LifeMOD (Life Modeler, Inc., San Clemente, CA) for biomechanical analyses of different resistive exercises such as squat and dead-lift. Using motion capture data from ground test subjects, the ExPC developed biomechanical exercise models in LifeMOD. The Adams ARED device module was then integrated with the exercise subject model into one integrated dynamic model. This presentation will describe the

    The use of recreational drugs of abuse continues to expand without limitations to national boundaries, social status, race, or education. Beyond the prevalence of illicit drug use and dependence, their contribution to the global burden of disease and death are large and troubling. All medical providers should be aware of the evolving drugs of abuse and their medical and social consequences. In addition to heroin and stimulants such as cocaine and methamphetamine, new designer stimulants called "bath salts" and cannabinoids called "spice," along with the abuse of prescription drugs and volatile substances, are now widely recognized problems in many societies. The wide variety and continuingly expanding clinical manifestations of toxicity of recreational drugs of abuse is not widely appreciated by clinicians. This edition attempts to summarize six major classes of drugs of abuse and their clinical effects with special emphasis on their immunological and respiratory effects.

  2. Abuse of prescription drugs.

    1990-01-01

    An estimated 3% of the United States population deliberately misuse or abuse psychoactive medications, with severe consequences. According to the National Institute on Drug Abuse, more than half of patients who sought treatment or died of drug-related medical problems in 1989 were abusing prescription drugs. Physicians who contribute to this problem have been described by the American Medical Association as dishonest--willfully misprescribing for purposes of abuse, usually for profit; disabled by personal problems with drugs or alcohol; dated in their knowledge of current pharmacology or therapeutics; or deceived by various patient-initiated fraudulent approaches. Even physicians who do not meet any of these descriptions must guard against contributing to prescription drug abuse through injudicious prescribing, inadequate safeguarding of prescription forms or drug supplies, or acquiescing to the demands or ruses used to obtain drugs for other than medical purposes.

    BACKGROUND: Several case reports and epidemiological studies have raised concern about the abuse potential of pregabalin, the use of which has increased substantially over the last decade. Pregabalin is, in some cases, used for recreational purposes and it has incurred attention among drug abusers...... for causing euphoric and dissociative effects when taken in doses exceeding normal therapeutic dosages or used by alternative routes of administration, such as nasal insufflation or venous injection. The magnitude of the abuse potential and the mechanism behind it are not fully known. OBJECTIVE: The aim...... of this study was to present a systematic review of the data concerning the abuse potential of pregabalin. METHODS: We performed a systematic literature search and reviewed the preclinical, clinical and epidemiological data on the abuse potential of pregabalin. RESULTS: We included preclinical (n = 17...

  4. Child sexual abuse.

    Science.gov (United States)

    Johnson, Charles Felzen

    Child sexual abuse is a worldwide concern. It is an insidious, persistent, and serious problem that, depending on the population studied and definition used, affects 2-62% of women and 3-16% of men as victims. Pain and tissue injury from child sexual abuse can completely heal in time, but psychological and medical consequences can persist through adulthood. Associated sexually transmitted diseases (such as HIV) and suicide attempts can be fatal. All physicians who treat children should be aware of the manifestations and consequences of child sexual abuse, and should be familiar with normal and abnormal genital and anal anatomy of children. This aim is best accomplished through training and routine examination of the anus and genitalia of children. Because as many as 96% of children assessed for suspected sexual abuse will have normal genital and anal examinations, a forensic interview by a trained professional must be relied on to document suspicion of abuse.

  5. The ADAM project: a generic web interface for retrieval and display of ATLAS TDAQ information

    2012-01-01

    This paper describes a new approach to the visualization of information about the operation of the ATLAS Trigger and Data Acquisition system. ATLAS is one of the two general purpose detectors positioned along the Large Hadron Collider at CERN. Its data acquisition system consists of several thousand computers interconnected via multiple gigabit Ethernet networks, that are constantly monitored via different tools. Operational parameters ranging from the temperature of the computers to the network utilization are stored in several databases for later analysis. Although the ability to view these data-sets individually is already in place, currently there is no way to view this data together, in a uniform format, from one location. The ADAM project has been launched in order to overcome this limitation. It defines a uniform web interface to collect data from multiple providers that have different structures. It is capable of aggregating and correlating the data according to user defined criteria. Finally, it visualizes the collected data using a flexible and interactive front-end web system. Structurally, the project comprises of 3 main levels of the data collection cycle: The Level 0 represents the information sources within ATLAS. These providers do not store information in a uniform fashion. The first step of the project was to define a common interface with which to expose stored data. The interface designed for the project originates from the Google Data Protocol API. The idea is to allow read-only access to data providers, through HTTP requests similar in format to the SQL query structure. This provides a standardized way to access this different information sources within ATLAS. The Level 1 can be considered the engine of the system. The primary task of the Level 1 is to gather data from multiple data sources via the common interface, to correlate this data together, or over a defined time series, and expose the combined data as a whole to the Level 2 web

Entende-se que esta concepção do mercado como ordem social aparece originariamente na história do pensamento econômico e na história das ideias através da solução de Adam Smith frente aos filósofos do contrato e avança, analiticamente, um século após, na tentativa de demonstração lógico-matemática da Teoria do Equilíbrio Geral em Walras para adquirir a souplesse teórica necessária a sua sobrevivência, no século XX, na teoria de Hayek, em que a história realizaria o autodesenvolvimento da ordem do mercado. O texto percorre as filiações filosóficas e as implicações metodológicas das teorias do mercado desses grandes autores, mostrando as formas diferenciadas que elas assumem: ordem natural para Smith, ordem racional para Walras e ordem espontânea para Hayek.The objective of the article is to critically present the liberal theories of Adam Smith, Leon Walras and F. A. Hayek, underlining what they have in common, that is, the idea of market as a general theory of society and the construction of scientific attributes that make possible the understanding of the supremacy of market order against other forms of social organization. It is assumed that this conception of market as social order appears originally in the history of economical thought and in the history of ideas through Adam Smith's solution against contract philosophers and that it advances analytically, a century later, in the attempt of logic-mathematic demonstration in Walras, to acquire the necessary theoretical souplesse for its survival, in the XX century, in the Darwinian adventures of the Austrian school libertarians, specially Hayek, for whom history would realize the self-development of the market.

    . Moreover, ADAM12-expressing cells were more prone to apoptosis, which could be prevented by treating the cells with beta1-activating antibodies. A reduced and re-organized fibronectin-rich extracellular matrix accompanied these changes. In addition, beta1 integrin was more readily extracted with Triton X......-100 from cells overexpressing ADAM12 than from control cells. Collectively, these results show that surface expression of ADAM12 impairs the function of beta1 integrins and, consequently, alters the organization of the actin cytoskeleton and extracellular matrix. These events may be necessary...

    The atmosphere within the work setting speaks volumes about your culture, and is often a primary factor in recruitment and retention (or turnover) of staff. Workplace tension and abuse are significant contributing factors as to why nurses are exiting workplaces--and even leaving the profession. Abuse can take many forms from inappropriate interpersonal communication to sexual harassment and even violence. Administrators should adopt a zero tolerance policy towards abusive communication. Addressing peer behavior is essential, but positive behavior must also be authentically modeled from the CNO and other nursing leaders. Raising awareness and holding individuals accountable for their behavior can lead to a safer and more harmonious work environment.

  1. Sir John Adams: his legacy to the world of particle accelerators

    CERN Document Server

    Wilson, E J N

    2011-01-01

    John Adams acquired an unrivalled reputation for his leading part in designing and constructing the Proton Synchrotron (PS) in CERN’s early days. In 1968, and after several years heading a fusion laboratory in the UK, he came back to Geneva to pilot the Super Proton Synchrotron (SPS) project to approval and then to direct its construction. By the time of his early death in 1984 he had built the two flagship proton accelerators at CERN and, during the second of his terms as Director-General, he laid the groundwork for the proton–antiproton collider which led to the discovery of the intermediate vector boson. How did someone without any formal academic qualification achieve this? What was the magic behind his leadership? The speaker, who worked many years alongside him, will discuss these questions and speculate on how Sir John Adams might have viewed today’s CERN.

  2. ADAM10 mediates vascular injury induced by Staphylococcus aureus α-hemolysin.

    Powers, Michael E; Kim, Hwan Keun; Wang, Yang; Bubeck Wardenburg, Juliane

    2012-08-01

    Staphylococcus aureus is a leading cause of bacteremia and sepsis. The interaction of S. aureus with the endothelium is central to bloodstream infection pathophysiology yet remains ill-understood. We show herein that staphylococcal α-hemolysin, a pore-forming cytotoxin, is required for full virulence in a murine sepsis model. The α-hemolysin binding to its receptor A-disintegrin and metalloprotease 10 (ADAM10) upregulates the receptor's metalloprotease activity on endothelial cells, causing vascular endothelial-cadherin cleavage and concomitant loss of endothelial barrier function. These cellular injuries and sepsis severity can be mitigated by ADAM10 inhibition. This study therefore provides mechanistic insight into toxin-mediated endothelial injury and suggests new therapeutic approaches for staphylococcal sepsis.

  3. Cardboard Boxes and Invisible Fences: Homelessness and Public Space in City of Victoria v. Adams

    Sarah Buhler

    2009-02-01

    Full Text Available This paper analyzes the recent decision of the British Columbia Supreme Court in City of Victoria v. Adams. Specifically, the paper considers three interlocking themes that emerge from the decision: (1 the nature of “public space” in the context of homelessness; (2 the autonomy of homeless individuals; and (3 the meaning and value of the “homeless body.” With reference to each theme, the paper explores how the judgment in Adams grapples with the purportedly normative “Law and Economics”- type arguments put forth by the City of Victoria. By drawing on insights from Critical Legal Studies theory and feminist jurisprudence, the paper shows that Adams subverts and destabilizes certain “normative” perspectives about public space and homelessness. However, the paper goes on to argue that in its conflation of “cardboard box” shelters with the “invisible fences” envisioned by Justice Wilson in Morgentaler, Adams presents an ambiguous victory for anti-poverty advocates. The paper argues that the decision may serve to increase barriers for a broader and more progressive understanding of section 7 in the future. Dans cet article, on analyse le jugement récent de la Cour Suprême de la Colombie Britannique dans City of Victoria v. Adams. Plus précisément, on considère trois thèmes qui ressortent du jugement et qui s’entrecroisent : (1 la nature d’«espace public» dans le contexte de l’itinérance; (2 l’autonomie des sans-abri; et (3 la signification et la valeur du «corps sans abri». En rapport avec chaque thème, on explore comment l’arrêt Adams compose avec les arguments supposément normatifs du genre «La Loi et l’Économie» avancés par la ville de Victoria. En s’inspirant de perceptions tirées de la théorie des Critical Legal Studies et de la jurisprudence féministe, l’auteure démontre que l’arrêt Adams subvertit et déséquilibre certaines perspectives «normatives» au sujet de l

    Matrix metalloproteinases (MMPs), in particular MMP-2, MMP-9 and MMP-14, play a key role in various aspects of cancer pathology. Likewise, ADAMs (a disintegrin and metalloproteinases), including ADAM12, are upregulated in malignant tumors and contribute to the pathology of cancers. Here, we show...... degradation was stimulated and tumor cell apoptosis was decreased, with reduced expression of the pro-apoptotic proteins BCL2L11 and BIK.

  10. Inflammasome in drug abuse.

    Science.gov (United States)

    Xu, Enquan; Liu, Jianuo; Wang, Xiaobei; Xiong, Huangui

    2017-01-01

    Drug abuse disorders refer to a set of related negative health implications associated with compulsive drug seeking and use. Because almost all addictive drugs act on the brain, many of them cause neurological impairments after long-term abuse. Neuropathological studies have revealed a widespread impairment of the cellular elements. As the key components to limit the damage of neural cells, CNS immune system is also found affected by these drugs, directly or indirectly. It has been shown that drugs of abuse alter neuroimmune gene expression and signaling. Growing studies on neuroimmune factors further demonstrate their indispensable role in drugs-induced neurotoxicity. As an important proinflammatory intracellular receptor, inflammasome is activated in many neurodegenerative diseases in response to a broad range of damage-associated molecular patterns (DAMPs) signals. In the cases of drug abuse, especially in those with comorbid of HIV infection and sustained pain, inflammasome activation significantly promotes the neuroinflammation-associated toxicities. To understand inflammasome in drug-associated neurotoxic activity, we reviewed the role played by inflammasome in drug abuse-induced microglial neurotoxicity and evaluated the potential of imflammasone as a therapeutic target for drug abuse disorders based on recent development of various selective small-molecular inflammasome inhibitors.

    123 I-ADAM is a novel radioligand for imaging of the brain serotonin transporters (SERTs). Traditionally, the analysis of brain receptor studies has been based on observer-dependent manual region of interest definitions and visual interpretation. Our aim was to create a template for automated image registrations and volume of interest (VOI) quantification and to show that an automated quantification method of 123 I-ADAM is more repeatable than the manual method. Patients, methods: A template and a predefined VOI map was created from 123 I-ADAM scans done for healthy volunteers (n=15). Scans of another group of healthy persons (HS, n=12) and patients with bulimia nervosa (BN, n=10) were automatically fitted to the template and specific binding ratios (SBRs) were calculated by using the VOI map. Manual VOI definitions were done for the HS and BN groups by both one and two observers. The repeatability of the automated method was evaluated by using the BN group. Results: For the manual method, the interobserver coefficient of repeatability was 0.61 for the HS group and 1.00 for the BN group. The intra-observer coefficient of repeatability for the BN group was 0.70. For the automated method, the coefficient of repeatability was 0.13 for SBRs in midbrain. Conclusion: An automated quantification gives valuable information in addition to visual interpretation decreasing also the total image handling time and giving clear advantages for research work. An automated method for analysing 123 I-ADAM binding to the brain SERT gives repeatable results for fitting the studies to the template and for calculating SBRs, and could therefore replace manual methods.

    Aim: Autoradiography with radioluminography is a delicate method to characterize newly developed radiotracers and to apply them to pharmacological studies. Herein, we reported a biodistribution result of [I-123] ADAM (2-((2-((dimethylamino)methyl)phenyl)thio)-5- iodophenylamine) in mice brain quantitatively using imaging plates. Materials and Methods: 1mCi [I-123] ADAM was injected into male ICR mice through tail veins. Brains were removed at sequential time points ranging from 0.5hr to 4hr after injection. The whole brain was cut into 14mm thick coronal sections using a cyrotome. The sections were thaw-mounted on glass plate and apposed placed on an imaging plate with filter paper standards for 24 hours. Imaging reading was done by a Fuji FLA5000 device. Regions of interest were placed on the globus pallidus, hypothalamus, substantia nigra, raphe nuclei and cerebellum corresponding to the sterotaxic atlas, and the PSL/mm 2 values were measured. The specific binding was expressed as the ratios of (targets - cerebellum) to cerebellum. Results: Autoradiography study of brain showed that the [I-123] ADAM was accumulated at serotonin transporter rich sites, including the olfactory tubercle, globus pallidus, thalamus nuclei, hypothalamus, substantia nigra, interpeduncular nucleus, amygdala and raphe nuclei. Biodistribution of [I-123] ADAM in mice brain using quantitative autoradiography method showed a high specific binding in the substantia nigra and hypothalamus and the time-activity curve peaked at 120 min post-injection. Compatible specific binding result was achieved in the region of hypothalamus as compared with previous study by other group using conventional tissue micro-dissection method (Synapse 38:403-412, 2000). However, higher specific binding was observed in certain small brain regions including substantia nigra, raphe nuclei due to improved spatial resolution of the quantitative autoradiography technique. Conclusion: Our result showed that the

  15. ADAM: An Accident Diagnostic,Analysis and Management System - Applications to Severe Accident Simulation and Management

    2002-01-01

    The Accident Diagnostic, Analysis and Management (ADAM) computer code has been developed as a tool for on-line applications to accident diagnostics, simulation, management and training. ADAM's severe accident simulation capabilities incorporate a balance of mechanistic, phenomenologically based models with simple parametric approaches for elements including (but not limited to) thermal hydraulics; heat transfer; fuel heatup, meltdown, and relocation; fission product release and transport; combustible gas generation and combustion; and core-concrete interaction. The overall model is defined by a relatively coarse spatial nodalization of the reactor coolant and containment systems and is advanced explicitly in time. The result is to enable much faster than real time (i.e., 100 to 1000 times faster than real time on a personal computer) applications to on-line investigations and/or accident management training. Other features of the simulation module include provision for activation of water injection, including the Engineered Safety Features, as well as other mechanisms for the assessment of accident management and recovery strategies and the evaluation of PSA success criteria. The accident diagnostics module of ADAM uses on-line access to selected plant parameters (as measured by plant sensors) to compute the thermodynamic state of the plant, and to predict various margins to safety (e.g., times to pressure vessel saturation and steam generator dryout). Rule-based logic is employed to classify the measured data as belonging to one of a number of likely scenarios based on symptoms, and a number of 'alarms' are generated to signal the state of the reactor and containment. This paper will address the features and limitations of ADAM with particular focus on accident simulation and management. (authors)

    2013-12-01

    A close correlation between asthma and palm dermatoglyphic patterns has been observed in previous studies, but the underlying genetic mechanisms have not been investigated. A disintegrin and metalloprotein‑33 (ADAM33) polymorphisms are important in the development of asthma and other atopic diseases. To investigate the underlying mechanisms of the association between asthma and distinctive palm dermatoglyphic patterns, thirteen ADAM33 single‑nucleotide polymorphisms (SNPs) were analyzed for the association between asthma and palm dermatoglyphic patterns in a population of 400 asthmatic patients and 200 healthy controls. Based on the results, five SNPs, rs44707 (codominant model, P=0.031; log‑additive model, P=0.0084), rs2787094 (overdominant model, P=0.049), rs678881 (codominant model, P=0.028; overdominant model, P=0.0083), rs677044 (codominant model, P=0.013; log‑additive model, P=0.0033) and rs512625 (dominant model, P=0.033), were associated with asthma in this population. Two SNPs, rs44707 (dominant model, P=0.042) and rs2787094 (codominant model, P=0.014; recessive model, P=0.0038), were observed in the asthma patients with the distinctive palm pattern. As rs44707 and rs2787094 are associated with asthma and a distinctive palm pattern, the data suggest that ADAM33 polymorphisms are correlated with asthma and may be the underlying genetic basis of the association between asthma and palm dermatoglyphic patterns.

In 1968, and after several years heading a fusion laboratory in the UK, he came back to Geneva to pilot the SPS project to approval and then to direct its construction. At the time of his untimely death in 1984 he had built Europe’s two largest proton accelerators at CERN. He went on, during the second of his terms as DG, to lay the groundwork for the proton-antiproton collider which led to the discovery of the intermediate vector boson. How did someone without any formal academic qualification achieve this? What was the magic behind his leadership? How did he achieve political success with the Member States of CERN in turning the almost hopeless quest for approval of the SPS to CERN’s advantage? How did he view his US counterpart, R. R. Wilson?

    The level of serotonin was regulated by serotonin transporter (SERT), which is a decisive protein in regulation of serotonin neurotransmission system. Many psychiatric disorders and therapies were also related to concentration of cerebral serotonin. I-123 ADAM was the novel radiopharmaceutical to image SERT in brain. The aim of this study was to measure reliability of SERT densities of healthy volunteers by automated anatomical labeling (AAL) method. Furthermore, we also used statistic parametric mapping (SPM) on a voxel by voxel analysis to find difference of cortex between test and retest of I-123 ADAM single photon emission computed tomography (SPECT) images. Twenty-one healthy volunteers were scanned twice with SPECT at 4 h after intravenous administration of 185 MBq of {sup 123}I-ADAM. The image matrix size was 128x128 and pixel size was 3.9 mm. All images were obtained through filtered back-projection (FBP) reconstruction algorithm. Region of interest (ROI) definition was performed based on the AAL brain template in PMOD version 2.95 software package. ROI demarcations were placed on midbrain, pons, striatum, and cerebellum. All images were spatially normalized to the SPECT MNI (Montreal Neurological Institute) templates supplied with SPM2. And each image was transformed into standard stereotactic space, which was matched to the Talairach and Tournoux atlas. Then differences across scans were statistically estimated on a voxel by voxel analysis using paired t-test (population main effect: 2 cond's, 1 scan/cond.), which was applied to compare concentration of SERT between the test and retest cerebral scans. The average of specific uptake ratio (SUR: target/cerebellum-1) of {sup 123}I-ADAM binding to SERT in midbrain was 1.78{+-}0.27, pons was 1.21{+-}0.53, and striatum was 0.79{+-}0.13. The cronbach's {alpha} of intra-class correlation coefficient (ICC) was 0.92. Besides, there was also no significant statistical finding in cerebral area using SPM2

    The cranial neural crest (CNC) is a population of cells that arises from the lateral part of the developing brain, migrates ventrally and coordinates the entire craniofacial development of vertebrates. Many molecules are involved in CNC migration including the transmembrane metalloproteases ADAM13 and 19. We have previously shown that these ADAMs cleave a number of extracellular proteins and modify the transcription of a number of genes, and that both of these activities are important for cell migration. Here we show that the knock down of ADAM13 inhibits CNC migration in vivo but not in vitro, indicating that ADAM13 function is required in the 3-dimentional context of the embryo. We further show that the migration of CNC that do not express ADAM13 and ADAM19 can be rescued in vivo by co-grafting wild type CNC. Furthermore, the migration of CNC lacking ADAM13 can be rescued by mechanically separating the CNC from the surrounding ectoderm and mesoderm. Finally, we show that ADAM13 function is autonomous to CNC tissue, as the migration of morphant CNC can only be rescued by ADAM13 expression in the CNC and not the surrounding tissues. Together our results suggest that ADAM13 changes CNC interaction with the extracellular environment and that this change is necessary for their migration in vivo. PMID:22683825

    Although buprenorphine abusers are a common clinical entity, literature on them is rare in Nepal. To assess whether injectable opioid abusers are any different a subgroup vis-a-vis brown sugar abusers in relation to their demographic and clinical profiles. Seventy-six opioid abusers, who were admitted over a period of one year, in our de-addiction center, were included in the present study. They were divided into two groups based on the history of the presence or absence of buprenorphine injection abuse in them. The demographic and clinical profiles of these two groups were studied and compared. The most characteristic opioid abuse pattern was the abuse of brown sugar through inhalation (chasing). A total of 32 (42.1%) among them had a history of injectable drug abuse (IDU). Most characteristic buprenorphine abuse pattern seen was an evolution from injectable buprenorphine to triple injection to brown sugar abuse (Reverse Transition). Injection buprenorphine abusers, who attended our clinic, were older in age and had a history of a longer duration of abuse than their counterparts who abused opioid drugs through the inhalational route only. Their lifetime diagnosis revealed a polysubstance abuse pattern. They were more unstable, impulsive, and disorganized in their behavior pattern, suggestive of the presence of inadequate personality traits. There were high instances of injection-related side effects in the form of the presence of thrombophlebitis, HIV positivity, and clinical AIDS in them. Findings of the current research indicate the presence of a subgroup of patient population among opioid abusers with a history of injectable buprenorphine abuse, with characteristic personality traits, pattern of drug abuse, and associated physical complications resulting from it.

    An Airborne Data Analysis/Monitor System (ADAMS), a ROLM 1666 computer based system installed onboard test airplanes used during experimental testing is evaluated. In addition to the 1666 computer, the ADAMS hardware includes a DDC System 90 fixed head disk and a Miltape DD400 floppy disk. Boeing designed a DMA interface to the data acquisition system and an intelligent terminal to reduce system overhead and simplify operator commands. The ADAMS software includes RMX/RTOS and both ROLM FORTRAN and assembly language are used. The ADAMS provides real time displays that enable onboard test engineers to make rapid decisions about test conduct thus reducing the cost and time required to certify new model airplanes, and improved the quality of data derived from the test, leading to more rapid development of improvements resulting in quieter, safer, and more efficient airplanes. The availability of airborne data processing removes most of the weather and geographical restrictions imposed by telemetered flight test data systems. A data base is maintained to describe the airplane, the data acquisition system, the type of testing, and the conditions under which the test is performed.

    Many new emerging drugs of abuse are marketed as legal highs despite being labeled "not for human consumption" to avoid regulation. The availability of these substances over the Internet and in "head shops" has lead to a multitude of emergency department visits with severe complications including deaths worldwide. Despite recent media attention, many of the newer drugs of abuse are still largely unknown by health care providers. Slight alterations of the basic chemical structure of substances create an entirely new drug no longer regulated by current laws and an ever-changing landscape of clinical effects. The purity of each substance with exact pharmacokinetic and toxicity profiles is largely unknown. Many of these substances can be grouped by the class of drug and includes synthetic cannabinoids, synthetic cathinones, phenethylamines, as well as piperazine derivatives. Resultant effects generally include psychoactive and sympathomimetic-like symptoms. Additionally, prescription medications, performance enhancing medications, and herbal supplements are also becoming more commonly abused. Most new drugs of abuse have no specific antidote and management largely involves symptom based goal directed supportive care with benzodiazepines as a useful adjunct. This paper will focus on the history, epidemiology, clinical effects, laboratory analysis, and management strategy for many of these emerging drugs of abuse. Copyright © 2014 Elsevier Inc.

  15. Effectiveness of Inhalant Abuse Legislation.

    Batis, Jeffery C

    2017-01-28

    Since peaking in the 1990s, inhalant abuse has steadily decreased over the past two decades. Concurrently, nearly every state has passed legislation aimed at minimizing inhalant abuse. While males have historically been more likely to abuse inhalants than females, there is no longer a sex effect in self-reported rates of inhalant abuse. The objective of the present study is to evaluate the effect of anti-inhalant abuse legislation on self-reported rates of inhalant abuse, in high school age males and females. Beginning in 1993, the CDC's biannual Youth Risk Behavior Surveillance Survey asked respondents if they have ever used inhalants to get high. Data from these surveys were collected, along with the date of passage of anti-inhalant abuse legislation in 46 of 50 states. ANOVAs were conducted to assess the effect of legislation on self-reported inhalant abuse rates. There were no significant main effects or interactions that demonstrated that inhalant abuse rates decreased in males or females following passage of legislation aimed at decreasing inhalant abuse. Conclusion/Importance: To date, 46 of 50 states have passed laws aimed at minimizing inhalant abuse, and while inhalant abuse rates have been decreasing for the past two decades, there is no evidence that this decline is related to enactment of these laws. Further research is needed to determine the cause of the decrease in inhalant abuse. The laws may benefit from amendments to include options for treatment.

  16. Chronic time abuse.

    2004-06-01

    Anyone who has ever managed people who abuse time--whether they are chronic procrastinators or individuals who work obsessively to meet deadlines weeks in advance--knows how disruptive they can be to a business's morale and operating efficiency. But lessons in time management will have no impact on these employees. That's because real time abuse results from psychological conflict that neither a workshop nor a manager's cajoling can cure. Indeed, the time abuser's quarrel isn't even with time but rather with a brittle self-esteem and an unconscious fear of being evaluated and found wanting. This article describes four types of time abusers typically encountered in the workplace: Perfectionists are almost physically afraid of receiving feedback. Their work has to be "perfect," so they can increase their likelihood of earning a positive evaluation or at least avoid getting a negative one. Preemptives try to be in control by handing in work far earlier than they need to, making themselves unpopular and unavailable in the process. People pleasers commit to far too much work because they find it impossible to say no. Procrastinators make constant (and often reasonable-sounding) excuses to mask a fear of being found inadequate in their jobs. Managing these four types of people can be challenging, since time abusers respond differently from most other employees to criticism and approval. Praising a procrastinator when he is on time, for instance, will only exacerbate the problem, because he will fear that your expectations are even higher than before. In fact, some time abusers, like the perfectionist, may need professional treatment. This article will give you insight into why they are the way they are--and what can be done to help them manage their problems.

    2007-02-01

    Abuse of anabolic-androgenic steroids (AAS) by members of fitness centers and others in Germany has reached alarming dimensions. The health care system provides the illegal AAS to 48.1 % of abusers. Physicians are involved in illegal prescription of AAS and monitoring of 32.1 % of AAS abusers. Besides health-threatening cardiovascular, hepatotoxic and psychiatric long-term side effects of AAS, acne occurs in about 50 % of AAS abusers and is an important clinical indicator of AAS abuse, especially in young men 18-26 years of age. Both acne conglobata and acne fulminans can be induced by AAS abuse. The dermatologist should recognize bodybuilding acne, address the AAS abuse, and warn the patient about other potential hazards.

    The currently available medications for the treatment of drug abuse have had only limited success. Anti-addiction vaccines, aimed at eliciting antibodies that block the pharmacological effects of drugs, have great potential for treating drug abuse. We review the status of two vaccines that are undergoing clinical trials (for cocaine and nicotine addiction) and two that are still in preclinical development (for methamphetamine and heroin addiction). We also outline the challenges and ethical concerns associated with the development of anti-addiction vaccines and their use as future therapeutics.

  19. Evaluation of ADAM-12 as a diagnostic biomarker of ectopic pregnancy in women with a pregnancy of unknown location.

    Full Text Available Ectopic pregnancy (EP remains the most life-threatening acute condition in modern gynaecology. It remains difficult to diagnose early and accurately. Women often present at emergency departments in early pregnancy with a 'pregnancy of unknown location' (PUL and diagnosis/exclusion of EP is challenging due to a lack of reliable biomarkers. Recent studies suggest that serum levels of a disintegrin and metalloprotease protein-12 (ADAM-12 can be used differentiate EP from viable intrauterine pregnancy (VIUP. Here we describe a prospective study evaluating the performance of ADAM-12 in differentiating EP from the full spectrum of alternative PUL outcomes in an independent patient cohort.Sera were collected from 120 patients at their first clinical presentation with a PUL and assayed for ADAM-12 by ELISA. Patients were categorized according to final pregnancy outcomes. Serum ADAM-12 concentrations were increased in women with histologically-confirmed EP (median 442 pg/mL; 25%-75% percentile 232-783 pg/mL compared to women with VIUP (256 pg/mL; 168-442 pg/mL or miscarriage (192 pg/mL; 133-476 pg/mL. Serum ADAM-12 did not differentiate histologically-confirmed EP from spontaneously resolving PUL (srPUL (416 pg/mL; 154-608 pg/mL. The diagnostic potential of ADAM-12 was only significant when 'ambiguous' PUL outcomes were excluded from the analysis (AROC = 0.6633; P = 0.03901.When measured in isolation, ADAM-12 levels had limited value as a diagnostic biomarker for EP in our patient cohort. The development of a reliable serum biomarker-based test for EP remains an ongoing challenge.

  20. Endothelial deletion of ADAM17 in mice results in defective remodeling of the semilunar valves and cardiac dysfunction in adults

    Global inactivation of the metalloproteinase ADAM17 during mouse development results in perinatal lethality and abnormalities of the heart, including late embryonic cardiomegaly and thickened semilunar and atrioventricular valves. These defects have been attributed in part to a lack of ADAM17-mediated processing of HB-EGF, as absence of soluble HB-EGF results in similar phenotypes. Because valvular mesenchymal cells are largely derived from cardiac endothelial cells, we generated mice with a floxed Adam17 allele and crossed these animals with Tie2-Cre transgenics to focus on the role of endothelial ADAM17 in valvulogenesis. We find that although hearts from late-stage embryos with ablation of endothelial ADAM17 appear normal, an increase in valve size and cell number is evident, but only in the semilunar cusps. Unlike Hbegf−/− valves, ADAM17-null semilunar valves do not differ from controls in acute cell proliferation at embryonic day 14.5 (E14.5), suggesting compensatory processing of HB-EGF. However, levels of the proteoglycan versican are significantly reduced in mutant hearts early in valve remodeling (E12.5). After birth, aortic valve cusps from mutants are not only hyperplastic but also show expansion of the glycosaminoglycan-rich component, with the majority of adults exhibiting aberrant compartmentalization of versican and increased deposition of collagen. The inability of mutant outflow valve precursors to transition into fully mature cusps is associated with decreased postnatal viability, progressive cardiomegaly, and systolic dysfunction. Together, our data indicate that ADAM17 is required in valvular endothelial cells for regulating cell content as well as extracellular matrix composition and organization in semilunar valve remodeling and homeostasis.

    Pediatricians and other medical providers caring for children need to be aware of the dynamics in the significant relationship between substance abuse and child maltreatment. A caregiver's use and abuse of alcohol, marijuana, heroin, cocaine, methamphetamine, and other drugs place the child at risk in multiple ways. Members of the medical community need to understand these risks because the medical community plays a unique and important role in identifying and caring for these children. Substance abuse includes the abuse of legal drugs as well as the use of illegal drugs. The abuse of legal substances may be just as detrimental to parental functioning as abuse of illicit substances. Many substance abusers are also polysubstance users and the compounded effect of the abuse of multiple substances may be difficult to measure. Often other interrelated social features, such as untreated mental illness, trauma history, and domestic violence, affect these families.

    Formulating prescription opioids to limit abuse remains a priority. OROS® extended-release (ER) hydromorphone HCl (EXALGO®) may have low abuse potential. Three post-marketing studies of the relative abuse liability of OROS hydromorphone ER were conducted. Estimates of abuse, unadjusted and adjusted for prescription volume, were generated for OROS hydromorphone ER and comparators from Q2 2010 through Q2 2014 for a high-risk, substance abuse treatment population and the general population using poison control center data. Comparators were selected for compound, market penetration, and route of administration (ROA) profile. ROA comparisons were made among the substance abuse treatment population. Internet discussion was examined to determine abusers' interest in and desire for the OROS formulation. Examination of abuse prevalence among adults within substance abuse treatment, intentional poison exposures and Internet discussion levels generally support the hypothesis that OROS hydromorphone ER may have lower abuse potential than many other opioid products. OROS hydromorphone ER also appears to be abused less often by alternate ROAs (e.g., snorting and injection). Lower levels of online discussion were observed along with relatively low endorsement for abuse. Abuse of OROS hydromorphone ER was observed in high-risk substance abuse and general population samples but at a very low relative prevalence. Evidence suggests it may be less often abused by alternate ROAs than some comparators. Online data did not find evidence of high levels of desire for OROS hydromorphone ER by recreational abusers. Continued monitoring of this product's abuse liability is warranted.

    Human ADAM33 is a multiple-domain, type-I transmembrane zinc metalloprotease recently implicated in asthma susceptibility [Nature 418 (2002) 426]. To provide an active protease for functional studies, expression of a recombinant ADAM33 zymogen (pro-catalytic domains, pro-CAT) was attempted in several insect cells. The pro-CAT was cloned into baculovirus under the regulation of the polyhedron promoter and using either the honeybee mellitin or ADAM33 signal sequence. Sf9 or Hi5 cells infected with these recombinant viruses expressed the majority of the protein unprocessed and as inclusion bodies ( approximately 10 mg/L). On the other hand, similar constructs could be expressed, processed, and secreted by Drosophila S2 cells using a variety of constitutive (actin, pAc5.1) or inducible (metallothionein, PMT) promoters and leader sequences (e.g., native and BiP). Higher expression level of 10-fold was observed for the inducible system resulting in an average yield of 20 mg/L after purification. The majority of the catalytic domain purified from the Drosophila conditioned media remained associated with the pro-domain after several chromatography steps. An induction cocktail containing cadmium chloride and zinc chloride was subsequently developed for the PMT system as an alternative to using cupric sulfate or cadmium chloride as single inducers. The novel induction cocktail resulted in an increased ratio of secreted catalytic to pro-domain, and yielded milligram amounts of highly purified protease. The availability of this modified expression system facilitated purification of the wild type and several glycosylation mutants, one of which (N231Q) crystallized recently for X-ray structure determination [J. Mol. Biol. 335 (2003) 129].

    2015-02-01

    Drug abuse is a common problem and growing concern in the United States, and over the past decade, novel or atypical drugs have emerged and have become increasingly popular. Recognition and treatment of new drugs of abuse pose many challenges for health care providers due to lack of quantitative reporting and routine surveillance, and the difficulty of detection in routine blood and urine analyses. Furthermore, street manufacturers are able to rapidly adapt and develop new synthetic isolates of older drugs as soon as law enforcement agencies render them illegal. In this article, we describe the clinical and adverse effects and purported pharmacology of several new classes of drugs of abuse including synthetic cannabinoids, synthetic cathinones, salvia, desomorphine, and kratom. Because many of these substances can have severe or life-threatening adverse effects, knowledge of general toxicology is key in recognizing acute intoxication and overdose; however, typical toxidromes (e.g., cholinergic, sympathomimetic, opioid, etc.) are not precipitated by many of these agents. Medical management of patients who abuse or overdose on these drugs largely consists of supportive care, although naloxone may be used as an antidote for desomorphine overdose. Symptoms of aggression and psychosis may be treated with sedation (benzodiazepines, propofol) and antipsychotics (haloperidol or atypical agents such as quetiapine or ziprasidone). Other facets of management to consider include treatment for withdrawal or addiction, nutrition support, and potential for transmission of infectious diseases. © 2014 Pharmacotherapy Publications, Inc.

    Full Text Available Claudia L Reardon, Shane Creado Department of Psychiatry, University of Wisconsin School of Medicine and Public Health, Madison, WI, USA Abstract: Drug abuse occurs in all sports and at most levels of competition. Athletic life may lead to drug abuse for a number of reasons, including for performance enhancement, to self-treat otherwise untreated mental illness, and to deal with stressors, such as pressure to perform, injuries, physical pain, and retirement from sport. This review examines the history of doping in athletes, the effects of different classes of substances used for doping, side effects of doping, the role of anti-doping organizations, and treatment of affected athletes. Doping goes back to ancient times, prior to the development of organized sports. Performance-enhancing drugs have continued to evolve, with “advances” in doping strategies driven by improved drug testing detection methods and advances in scientific research that can lead to the discovery and use of substances that may later be banned. Many sports organizations have come to ban the use of performance-enhancing drugs and have very strict consequences for people caught using them. There is variable evidence for the performance-enhancing effects and side effects of the various substances that are used for doping. Drug abuse in athletes should be addressed with preventive measures, education, motivational interviewing, and, when indicated, pharmacologic interventions. Keywords: doping, athletes, steroids, drug abuse, mental illness

Due to the nature of the point kinetic equations, different predictor modifiers are used in order improve the precision of the approximations obtained. The results obtained with the prediction formulas and generalised corrections improve the precision when compared with previous methods and are valid for various forms of nuclear power and different time steps.

    El interés por sí mismo es, en Adam Smith, más que un axioma económico según el cual funciona el mercado, un principio antropológico cuya moderación racional permite que las actividades económicas en la sociedad comercial se desarrollen de una manera prudente y justa. Estas virtudes tienen en el filósofo escocés ciertos rasgos propios de una antropología materialista y mecanicista, iniciada por Thomas Hobbes. Se insertan además en un epicureísmo moderno mezclado con cierta narrativa estoica p...

    B cell activating factor (BAFF) provides B cells with essential survival signals. It binds to three receptors: BAFFR, TACI, and BCMA that are differentially expressed by B cell subsets. BAFFR is early expressed in circulating B cells and provides key signals for further maturation. Here, we report that highly regulated BAFFR processing events modulate BAFF responses. BAFFR processing is triggered by BAFF binding in B cells co-expressing TACI and it is executed by the metalloproteases ADAM10 and ADAM17. The degree of BAFF oligomerization, the expression of ADAM proteins in different B cell subsets, and the activation status of the cell determine the proteases involved in BAFFR processing. Inhibition of ADAM10 augments BAFF-dependent survival of primary human B cells, whereas inhibition of ADAM17 increases BAFFR expression levels on germinal center B cells. Therefore, BAFF-induced processing of BAFFR regulates BAFF-mediated B cell responses in a TACI-dependent manner. Copyright © 2017 The Author(s). Published by Elsevier Inc. All rights reserved.

    ADAM10, a member of a disintegrin and metalloprotease family, is an α-secretase capable of anti-amyloidogenic proteolysis of the amyloid precursor protein. Here, we present evidence for genetic association of ADAM10 with Alzheimer's disease (AD) as well as two rare potentially disease-associated non-synonymous mutations, Q170H and R181G, in the ADAM10 prodomain. These mutations were found in 11 of 16 affected individuals (average onset age 69.5 years) from seven late-onset AD families. Each mutation was also found in one unaffected subject implying incomplete penetrance. Functionally, both mutations significantly attenuated α-secretase activity of ADAM10 (>70% decrease), and elevated Aβ levels (1.5–3.5-fold) in cell-based studies. In summary, we provide the first evidence of ADAM10 as a candidate AD susceptibility gene, and report two potentially pathogenic mutations with incomplete penetrance for late-onset familial AD.

    Full Text Available Abstract Background Rhinitis and asthma are very common diseases involving genetic and environmental factors. Most patients with asthma also have rhinitis, which suggests the concept of 'one airway, one disease.' A disintegrin and metalloproteinase 33 (ADAM33 is the first asthma-susceptible gene to be discovered by positional cloning. To evaluate the potential influence of ADAM33 gene polymorphisms on allergic rhinitis (AR and allergic asthma (AS, a case-control study was conducted on the Han population of northeast China. Methods Six polymorphic sites (V4, T+1, T2, T1, S1, and Q-1 were genotyped in 128 patients with AR, 181 patients with AS, and 151 healthy controls (CTR. Genotypes were determined by the polymerase chain restriction fragment length polymorphism (PCR-RFLP method. Data were analyzed using the chi-square test with Haploview software. Results The single nucleotide polymorphisms (SNPs, V4 G/C, T+1 A/G, and T1 G/A, of the ADAM33 gene may be the causal variants in AR, whereas ADAM33 V4 G/C, T2 A/G, T1 G/A, and Q-1A/G may participate in the susceptibility of AS. Conclusion These results suggest that polymorphisms of the ADAM33 gene may modify individual susceptibility to AR and AS in a Chinese Han population.

    Background: Child sexual abuse with significant impact on victim's physical, mental and social health has now been recognized as existing on an appreciable scale worldwide. Diversity of opinions exist about the concept, types, prevalence and repercussions along with a paucity of systematic and scientific work in the developing world including Pakistan. Objective: This paper aims at reviewing the literature for clarification of concept, update of estimates and correlates, and to identify lines for future research. Data sources: The literature was search through BMJ-Medline for international data, supplemented by local data through CPSP-MEDLIP service. The search term child sexual abuse with associated sub-heads were used. No constraint of time period, publication type or source applied except english Language version Comparative findings: Wide variations identified in conceptual boundaries with consequent impact on prevalence estimates. Agreement found for its existence as an international problem with rates ranging from 7% - 36% for women and 3% - 29% for men. Female abused 1.5-3 times more than male with exponential high rates in age group 3-6 years and 8-11 years. In 2/3 cases the perpetrator identified belonged to nuclear or extended family. Significant association exists with early onset of psychiatric ailments like substance abuse, eating disorders, personality disorders, dissociative disorders and depression. Conclusion and Suggestion: The need for extensive research studies in immense in developing countries like Pakistan where environmental circumstances suggest its presence at rates higher than the identified elsewhere. In addition to facilitate awareness and perhaps to clarify the concept as well as the prevalence of child sexual abuse researchers need to select methodologies and instruments with international comparison in mind.

    2008-01-01

    Sex differences are present for all of the phases of drug abuse (initiation, escalation of use, addiction, and relapse following abstinence). While there are some differences among specific classes of abused drugs, the general pattern of sex differences is the same for all drugs of abuse. Females begin regularly self-administering licit and illicit drugs of abuse at lower doses than do males, use escalates more rapidly to addiction, and females are at greater risk for relapse following abstinence. In this review, sex differences in drug abuse are discussed for humans and in animal models. The possible neuroendocrine mechanisms mediating these sex differences are discussed.

    Full Text Available Background: Child abuse is a global problem and occurs in a variety of forms and is deeply rooted in cultural, economic and social practices. Child abuse is a behaviour which causes physical, psychological, emotional or sexual abuses, consequentlylead to damage of children,s health, peace of mind and education. Based on these considerations, the present study was conducted to investigate the prevalence of child abuse among junior high school students of Khoramabad in 2012. Materials and Methods: In this cross sectional study, 907 junior high school students randomly selected .Data collection tool was a multiple questionnaire incloding child and parents’ demographic information, and a physical emotional abuse and neglect questionnaire. It,s validity and reliability was done by content validity and Test re test. Data were analysed using SPSS v. 19. Results: The findings of this study showed that average age of the cases was 13.36±1.04 and 5.4% of them were always under physical abuse and the most physical abuse was slap on the face , 7.3% emotional abuse and 5.5% neglect. Statistical test showed a significant relation between abuses and parents, educational level, job, addiction and divorce. Conclusion: Results showed that child abuse is common among families, therefore, monitoring of children, ratification of rules supporting children, planing and administration of preventive educational programs can be effective to reduce child abuse.

  17. A mechanism of male germ cell apoptosis induced by bisphenol-A and nonylphenol involving ADAM17 and p38 MAPK activation.

    Directory of Open Access Journals (Sweden)

    Paulina Urriola-Muñoz

    Full Text Available Germ cell apoptosis regulation is pivotal in order to maintain proper daily sperm production. Several reports have shown that endocrine disruptors such as Bisphenol-A (BPA and Nonylphenol (NP induce germ cell apoptosis along with a decrease in sperm production. Given their ubiquitous distribution in plastic products used by humans it is important to clarify their mechanism of action. TACE/ADAM17 is a widely distributed extracellular metalloprotease and participates in the physiological apoptosis of germ cells during spermatogenesis. The aims of this work were: 1 to determine whether BPA and NP induce ADAM17 activation; and 2 to study whether ADAM17 and/or ADAM10 are involved in germ cell apoptosis induced by BPA and NP in the pubertal rat testis. A single dose of BPA or NP (50 mg/kg induces germ cell apoptosis in 21-day-old male rats, which was prevented by a pharmacological inhibitor of ADAM17, but not by an inhibitor of ADAM10. In vitro, we showed that BPA and NP, at similar concentrations to those found in human samples, induce the shedding of exogenous and endogenous (TNF-α ADAM17 substrates in primary rat Sertoli cell cultures and TM4 cell line. In addition, pharmacological inhibitors of metalloproteases and genetic silencing of ADAM17 prevent the shedding induced in vitro by BPA and NP. Finally, we showed that in vivo BPA and NP induced early activation (phosphorylation of p38 MAPK and translocation of ADAM17 to the cell surface. Interestingly, the inhibition of p38 MAPK prevents germ cell apoptosis and translocation of ADAM17 to the cell surface. These results show for the first time that xenoestrogens can induce activation of ADAM17 at concentrations similar to those found in human samples, suggesting a mechanism by which they could imbalance para/juxtacrine cell-to-cell-communication and induce germ cell apoptosis.

    Several studies have elucidated the significance of a disintegrin and metalloproteinase proteins (ADAMs) in PNS myelination, but there is no evidence if they also play a role in oligodendrogenesis and CNS myelination. Our study identifies ADAM17, also called tumor necrosis factor-α converting enzyme (TACE), as a novel key modulator of oligodendrocyte (OL) development and CNS myelination. Genetic deletion of TACE in oligodendrocyte progenitor cells (OPs) induces premature cell cycle exit and reduces OL cell survival during postnatal myelination of the subcortical white matter (SCWM). These cellular and molecular changes lead to deficits in SCWM myelination and motor behavior. Mechanistically, TACE regulates oligodendrogenesis by modulating the shedding of EGFR ligands TGFα and HB-EGF and, consequently, EGFR signaling activation in OL lineage cells. Constitutive TACE depletion in OPs in vivo leads to similar alterations in CNS myelination and motor behavior as to what is observed in the EGFR hypofunctional mouse line EgfrWa2. EGFR overexpression in TACE-deficient OPs restores OL survival and development. Our study reveals an essential function of TACE in oligodendrogenesis, and demonstrates how this molecule modulates EGFR signaling activation to regulate postnatal CNS myelination.

    Full Text Available En este artículo postularé que el orden liberal que propone Adam Smith en su obra es tanto técnica como moralmente superior a otros tipos de ordenamientos sociales, por cuanto la racionalidad que le subyace es la más adecuada para el ámbito de la vida humana que regula: el de la praxis. La superioridad y justificación técnica de las instituciones liberales se explica por su estructura abierta, dialógica y cooperativa, capaz de aprovechar los errores y aprender de la experiencia para acercarse, poco a poco, a un modelo que aumente la productividad global de cada institución en su ámbito específico. La justificación moral de este ordenamiento, por su parte, se apoya en el hasta ahora poco destacado respeto a la igualdad, o incluso igual dignidad de los seres humanos, que se infiere del tratamiento que Adam Smith da a la justicia y a el espectador imparcial en su obra.

  20. ADAM13 cleavage of cadherin-11 promotes CNC migration independently of the homophilic binding site.

    The cranial neural crest (CNC) is a highly motile population of cells that is responsible for forming the face and jaw in all vertebrates and perturbing their migration can lead to craniofacial birth defects. Cell motility requires a dynamic modification of cell-cell and cell-matrix adhesion. In the CNC, cleavage of the cell adhesion molecule cadherin-11 by ADAM13 is essential for cell migration. This cleavage generates a shed extracellular fragment of cadherin-11 (EC1-3) that possesses pro-migratory activity via an unknown mechanism. Cadherin-11 plays an important role in modulating contact inhibition of locomotion (CIL) in the CNC to regulate directional cell migration. Here, we show that while the integral cadherin-11 requires the homophilic binding site to promote CNC migration in vivo, the EC1-3 fragment does not. In addition, we show that increased ADAM13 activity or expression of the EC1-3 fragment increases CNC invasiveness in vitro and blocks the repulsive CIL response in colliding cells. This activity requires the presence of an intact homophilic binding site on the EC1-3 suggesting that the cleavage fragment may function as a competitive inhibitor of cadherin-11 adhesion in CIL but not to promote cell migration in vivo.

    Frailty is a circumstance of increased vulnerability to bad resolution of homeostasis after a stressor occasion, which increases the risk of adverse outcomes. Early detection of frailty in elderly patients is a must but is rarely in the Geriatric Outpatient settings. We conducted a study to see the frailty profile for geriatric patients in the outpatient clinic of RSUP H. Adam Malik Medan. A cross-sectional research with a descriptive method was in the Geriatric Outpatient Clinic of Adam Malik Hospital from July-September 2016. The population of this study was patients from the Geriatric Outpatient Clinic, and sampling was by using consecutive methods. Samples were by questionnaires assessing (FRAIL Scale).This study was140 patients. Based on age, the age group of 81-90 years was dominantly frail (53.8%). Most of the subjects worked as government employees (109 subjects), and most of them were robust (42.2%). Based on income, both groups were dominated by robust (38.3% and 41.3%, respectively). Based on BMI, most were robust with underweight 33.5%, normoweight 37.8%, and obese 44.7%. Among the 140 patients, frailty was in the 27.1% of the subjects and the contributing factors were Age, Gender, and Obesity.

    Full Text Available Adams-Oliver syndrome was first described in 1945 as a multiple congenital malformations association including aplasia cutis congenita and terminal transverse limb defects, along with cardiovascular and central nervous system anomalies. We report the case of a boy, prenatally diagnosed with a malformation of feet and right hand. At birth, a malformation of the skull was observed, at midline and right frontal, parietal and occipital region, with meningeal exposition. He presented with abnormal feet and right hand with hypoplastic fingers and also exhibiting cutis marmorata telangiectatica. Cardiac, abdominal and central nervous system malformations were excluded. He started a conservative approach based on daily dressings. The scalp defect closed at 4 months with this management strategy. At this age, a skull defect about 5 cm long was still perceptible by palpation of the area. The boy showed normal growth and neurologic development. No complications were reported. This report reinforces the effectiveness of conservative management strategies for extensive bone and epithelization defects in syndromes of aplasia cutis congenita like Adams-Oliver syndrome.

    An improved synthesis of N,N-dimethyl-2-(2-amino-4-[ 18 F]fluorophenylthio)benzylamine (4-[ 18 F]-ADAM, 2) as a potent serotonin transporter (SERT) imaging agent is described. Molecular orbital (MO) calculation predicts that N,N-dimethyl-2- (2-nitro-4-trimethylammoniumtrifluoromethanesulfonylphenylthio)benzamide (8) is probably a better precursor than N,N-dimethyl-2-(2,4-dinitrophenylthio)benzylamine (1) for preparing 2. Radioligand 2 was synthesized by the reaction of either precursor 1 or precursor 8 with K[ 18 F]/K 2.2.2 at 120 deg. C followed by reduction with BH 3 at 80 deg. C. The radiochemical yield (EOB) of 2 synthesized from precursor 1 and 8 was 5.7±2.4% (n=6) and 14.8±4.0% (n=5), respectively, in a synthesis time of 120 min from EOB. The specific activity of 2 was 3 Ci/μmol or 111 GBq/μmol (EOB). Thus, this new synthetic method has significantly improved the radiochemical yield of 4-[ 18 F]-ADAM and makes this radioligand more accessible to PET Centers without a cyclotron.

    Background: A novel radioiodine ligand [{sup 123}I] ADAM (2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine) has been suggested as a promising serotonin transporter (SERT) imaging agent for the central nervous system. In this study, the biodistribution of SERTs in the rabbit brain was investigated using [{sup 123}I] ADAM and mapping images of the same animal produced by both single-photon emission computed tomography (SPECT) and microautoradiography. A semiquantification method was adopted to deduce the optimum time for SPECT imaging, whereas the input for a simple fully quantitative tracer kinetic model was provided from arterial blood sampling data. Methods: SPECT imaging was performed on female rabbits postinjection of 185 MBq [{sup 123}I] ADAM. The time-activity curve obtained from the SPECT images was used to quantify the SERTs, for which the binding potential was calculated from the kinetic modeling of [{sup 123}I] ADAM. The kinetic data were analyzed by the nonlinear least squares method. The effects of the selective serotonin reuptake inhibitors fluoxetine and p-chloroamphetamine (PCA) on rabbits were also evaluated. After scanning, the same animal was sacrificed and the brain was removed for microautoradiography. Regions-of-interest were analyzed using both SPECT and microautoradiography images. The SPECT images were coregistered manually with the corresponding microautoradiography images for comparative study. Results: During the time interval 90-100 min postinjection, the peak specific binding levels in different brain regions were compared and the brain stem was shown to have the highest activity. The target-to-background ratio was 1.89{+-}0.02. Similar studies with fluoxetine and PCA showed a background level for SERT occupation. Microautoradiography demonstrated a higher level of anatomical details of the [{sup 123}I] ADAM distribution than that obtained by SPECT imaging of the rabbit brain. Conclusion: SPECT imaging of the rabbit brain with

    Full Text Available The contribution of Adam Smith for liberalism was great, but it is not limited to bringing an insane and unreasonable quest for freedom, as if all the costs were possible for such purpose. Adam Smith brings the birthplace of fundamental rights, to call for the need for recognition of individual liberties, although predicting problems for the exercise of such powers without limits. The idea of the text is to bring the initial outlook for the construction of fundamental rights in an individual prism and after its weighting in a mass spectrum as well as the subsequent discussion which should prevail.

    Full Text Available In Bangladesh, a large number of children are deprived of their basic human rights due to unacceptable health, nutrition, education as well as social conditions. In addition, children are exposed to severe forms of sexual, physical and mental abuses at home, in the work place, in institutions and other public places. The nature and extent of violence against children irrespective of age, sex and class has been increasing day by day. These include physical torture, rape, homicide and sometimes heinous attacks with acid. Children are also victims of child labor and trafficking, both of which are treated as the most severe form of child exploitation and child abuse in the world today. This review article is aimed to focus on the present situation of various forms of child abuses in our country.

The locus coeruleus and raphe nucleus fire during waking and slow wave sleep, with the pedunculopontine nucleus (PPN) firing during both waking and REM sleep, the states manifesting arousal-related EEG activity. Two important discoveries in the PPN in the last 10 years are, 1) that some PPN cells are electrically coupled, and 2) every PPN cell manifests high threshold calcium channels that allow them to oscillate at beta/gamma band frequencies. The role of arousal in drug abuse is considered here in terms of the effects of drugs of abuse on these two mechanisms. Drug abuse and the perception of withdrawal/relapse are mediated by neurobiological processes that occur only when we are awake, not when we are asleep. These relationships focus on the potential role of arousal, more specifically of RAS electrical coupling and gamma band activity, in the addictive process as well as the relapse to drug use.

    The Staphylococcus aureus toxin, α-hemolysin, is an important and well-studied virulence factor in staphylococcal infection. It is a soluble monomeric protein that, once secreted by the bacterium, forms a heptameric pore in the membrane of a broad range of host cell types. Hemolysin was recently discovered to bind and activate a disintegrin and metalloprotease 10 (ADAM10). In epithelial and endothelial cells, ADAM10 activation is required for the toxin's activity against these cells. In host monocytic cells, α-hemolysin activates the nucleotide-binding domain and leucine-rich repeat containing gene family, pyrin domain containing 3 (NLRP3) inflammasome leading to production of pro-inflammatory cytokines and cell death. We now show that ADAM10 is critical for α-hemolysin-mediated activation of the NLRP3 inflammasome in human monocytes as siRNA knockdown or chemical blockade of ADAM10-α-hemolysin interaction leads to diminished inflammasome activation and cell death by reducing the available ADAM10 on the cell surface. Unlike epithelial cell and endothelial cell damage, which requires α-hemolysin induced ADAM10 activation, ADAM10 protease activity was not required for NLRP3 inflammasome activation. This work confirms the importance of ADAM10 in immune activation by α-hemolysin, but indicates that host cell signal induction by the toxin is different between host cell types.

    Detecting elder abuse is challenging because it is a taboo, and many cases remain unreported. This study aimed to identify types of elder abuse and to investigate its associated risk factors. Retrospective analyses of 903 dossiers created at an Independent Complaints Authority for Old Age in the Canton of Zurich, Switzerland, from January 1, 2008 to October 31, 2012. Characteristics of victims and perpetrators, types of abuse, and associated risk factors related to the victim or the perpetrator were assessed. Bi- and multivariate analysis were used to identify abuse and neglect determinants. A total of 150 cases reflected at least one form of elder abuse or neglect; 104 cases were categorised as abuse with at least one type of abuse (overall 135 mentions), 46 cases were categorised as neglect (active or passive). Psychological abuse was the most reported form (47%), followed by financial (35%), physical (30%) and anticonstitutional abuse (18%). In 81% of the 150 cases at least two risk factors existed. In 13% no associated risk factor could be identified. Compared with neglect, elders with abuse were less likely to be a nursing home resident than living at home (odds ratio [OR] 0.02, 95% confidence interval [CI] 0.00-0.19). In addition, they were more likely to be cohabiting with their perpetrators (OR 18.01, 95% CI 4.43-73.19). For the majority of the reported elder abuse cases at least two associated risk factors could be identified. Knowledge about these red flags and a multifaceted strategy are needed to identify and prevent elder abuse.

    Abuse-deterrent formulations (ADFs) represent one novel strategy for curbing the potential of opioid abuse. We aim to compare and contrast the characteristics and applications of current abuse-deterrent opioid products in clinical practice. Literature searches were conducted in databases (Pubmed Medline, International Pharmaceutical Abstracts, Google Scholar) and official reports. Relevant data were screened and organized into: 1) epidemiology of opioid abuse, 2) mitigation strategies for reducing opioid abuse, 3) development of ADFs, and 4) clinical experience with these formulations. Increasing trends of opioid abuse and misuse have been reported globally. There are 5 types of abuse-deterrent opioid products: physical chemical barrier, combined agonist/antagonist, sequestered aversive agent, prodrug, and novel delivery system. The advantages and disadvantages of the 5 options are discussed in this review. A total of 9 products with abuse-deterrent labels have been approved by the Food and Drug Administration (FDA). The rates of abuse, diversion, and overdose deaths of these new products are also discussed. A framework for collecting in-time data on the efficacy, benefit and risk ratio, and cost-effectiveness of these new products is suggested to facilitate their optimal use. The present review did not utilize systematic review standards or meta-analytic techniques, given the large heterogeneity of data and outcomes reviewed. ADFs provide an option for inhibiting the abuse or misuse of oral opioid products by hindering extraction of the active ingredient, preventing alternative routes of administration, or causing aversion. Their relatively high costs, uncertain insurance policies, and limited data on pharmacoeconomics warrant collaborative monitoring and assessment by government agencies, pharmaceutical manufacturers, and data analysis services to define their therapeutic role in the future.

    The ADAMs (a disintegrin and metalloprotease) family of proteins is involved in a variety of cellular interactions, including cell adhesion and ecto- domain shedding. Here we show that ADAM 12 binds to cell surface syndecans. Three forms of recombinant ADAM 12 were used in these experiments......-dependent manner attach to ADAM 12 via members of the syndecan family. After binding to syndecans, mesenchymal cells spread and form focal adhesions and actin stress fibers. Integrin beta1 was responsible for cell spreading because function-blocking monoclonal antibodies completely inhibited cell spreading......, and chondroblasts lacking beta1 integrin attached but did not spread. These data suggest that mesenchymal cells use syndecans as the initial receptor for the ADAM 12 cysteine-rich domain-mediated cell adhesion, and then the beta1 integrin to induce cell spreading. Interestingly, carcinoma cells attached but did...

  1. The induction of C/EBPβ contributes to vitamin D inhibition of ADAM17 expression and parathyroid hyperplasia in kidney disease.

    Science.gov (United States)

    Arcidiacono, Maria Vittoria; Yang, Jing; Fernandez, Elvira; Dusso, Adriana

    2015-03-01

    In secondary hyperparathyroidism (SHPT), enhanced parathyroid levels of transforming growth factor-α (TGFα) increase EGF receptor (EGFR) activation causing parathyroid hyperplasia, high parathyroid hormone (PTH) and also reductions in vitamin D receptor (VDR) that limit vitamin D suppression of SHPT. Since anti-EGFR therapy is not an option in human SHPT, we evaluated ADAM17 as a therapeutic target to suppress parathyroid hyperplasia because ADAM17 is required to release mature TGFα, the most potent EGFR-activating ligand. Computer analysis of the ADAM17 promoter identified TGFα and C/EBPβ as potential regulators of the ADAM17 gene. Their regulation of ADAM17 expression, TGFα/EGFR-driven growth and parathyroid gland (PTG) enlargement were assessed in promoter-reporter assays in A431 cells and corroborated in rat and human SHPT, using erlotinib as anti-EGFR therapy to suppress TGFα signals, active vitamin D to induce C/EBPβ or the combination. While TGFα induced ADAM17-promoter activity by 2.2-fold exacerbating TGFα/EGFR-driven growth, ectopic C/EBPβ expression completely prevented this vicious synergy. Accordingly, in advanced human SHPT, parathyroid ADAM17 levels correlated directly with TGFα and inversely with C/EBPβ. Furthermore, combined erlotinib + calcitriol treatment suppressed TGFα/EGFR-cell growth and PTG enlargement more potently than erlotinib in part through calcitriol induction of C/EBPβ to inhibit ADAM17-promoter activity, mRNA and protein. Importantly, in rat SHPT, the correction of vitamin D deficiency effectively reversed the resistance to paricalcitol induction of C/EBPβ to suppress ADAM17 expression and PTG enlargement, reducing PTH by 50%. In SHPT, correction of vitamin D and calcitriol deficiency induces parathyroid C/EBPβ to efficaciously attenuate the severe ADAM17/TGFα synergy, which drives PTG enlargement and high PTH. © The Author 2014.

    ADAM28 (disintegrin and metalloproteinase 28), which was originally reported to be lymphocyte-specific, is over-expressed by carcinoma cells and plays a key role in cell proliferation and progression in human lung and breast carcinomas. We studied ADAM28 expression in human normal tissues and examined its biological function. By using antibodies specific to ADAM28, ADAM28 was immunolocalized mainly to epithelial cells in several tissues, including epididymis, bronchus and stomach, whereas lymphocytes in lymph nodes and spleen were negligibly immunostained. RT-PCR, immunoblotting and ELISA analyses confirmed the expression in these tissues, and low or negligible expression by lymphocytes was found in the lymph node and spleen. C1q was identified as a candidate ADAM28-binding protein from a human lung cDNA library by yeast two-hybrid system, and specific binding was demonstrated by binding assays, immunoprecipitation and surface plasmon resonance. C1q treatment of normal bronchial epithelial BEAS-2B and NHBE cells, both of which showed low-level expression of ADAM28, caused apoptosis through activation of p38 and caspase-3, and cell death with autophagy through accumulation of LC3-II and autophagosomes, respectively. C1q-induced cell death was attenuated by treatment of the cells with antibodies against the C1q receptor gC1qR/p33 or cC1qR/calreticulin. Treatment of C1q with recombinant ADAM28 prior to addition to culture media reduced C1q-induced cell death, and knockdown of ADAM28 using siRNAs increased cell death. These data demonstrate that ADAM28 is expressed by epithelial cells of several normal organs, and suggest that ADAM28 plays a role in cell survival by suppression of C1q-induced cytotoxicity in bronchial epithelial cells. © 2016 Federation of European Biochemical Societies.

    Full Text Available Drug abuse has become a global issue of concern. It affects not only individual users, but also their families and communities. Data were retrieved from the database of the Taiwan Surveillance System of Drug Abuse and Addiction Treatment (SSDAAT from 2002 to 2011, and 147,660 cases reported by medical institutions in Taiwan were reviewed. This study showed that the top five reported abused drugs by medical institutions during the last decade were heroin, methamphetamine, benzodiazepines, ketamine, and zolpidem. Heroin and methamphetamine continued to be the first two abused drugs reported by medical institutions. Heroin abuse was significant, but has shown a downward trend. However, emerging abused drugs, such as ketamine and zolpidem, presented upward trends. 3,4-Methylenedioxy-N-methylamphetamine (MDMA abuse seems to have re-emerged and has increased gradually since 2010. Injection without needle sharing has become the most common route of administration of abused drugs since 2002. The majority of causes for these reported drug abuses were drug dependence, followed by peer influence and stress relief. Hepatitis C was the most commonly reported infectious disease, followed by hepatitis B and AIDS in the drug abusers reported by medical institutions. It should be noted that access to drugs via the Internet increased year by year, and this is clearly an area needing constant monitoring.

    The major role of imaging in cases of suspected child abuse is to identify the physical injuries and to confirm the occurrence of abuse. In severely abused infants, the imaging findings may be the only evidence for a diagnosis of inflicted injury. Imaging may be the first clue to abuse in children seen with apparent other conditions and lead to appropriate measures to protect them from the risk of more serious injury. The radiologist must be familiar with imaging findings of inflicted injuries to fulfill these roles. (author)

    The U.S. Army is seeking to develop autonomous off-road mobile robots to perform tasks in the field such as supply delivery and reconnaissance in dangerous territory. A key problem to be solved with these robots is off-road mobility, to ensure that the robots can accomplish their tasks without loss or damage. We have developed a computer model of one such concept robot, the small-scale "T-1" omnidirectional vehicle (ODV), to study the effects of different control strategies on the robot's mobility in off-road settings. We built the dynamic model in ADAMS/Car and the control system in Matlab/Simulink. This paper presents the template-based method used to construct the ADAMS model of the T-1 ODV. It discusses the strengths and weaknesses of ADAMS/Car software in such an application, and describes the benefits and challenges of the approach as a whole. The paper also addresses effective linking of ADAMS/Car and Matlab for complete control system development. Finally, this paper includes a section describing the extension of the T-1 templates to other similar ODV concepts for rapid development.

    Full Text Available A multi-body dynamics simulation model of CJ20-25 AC contactor was established with Pro/E(Pro/Engineerin this paper. A coupling simulation with machine, electric, magnetic on the contactor has been achieved in this model. Dynamic parameters which were called use the secondary development technology of ADAMS. The dynamic contact pressure signal of an AC contactor was obtained with ADAMS’s own simultaneous solution such as electromagnetic suction, kinematics and dynamics equations. The simulation results and actual measurement of contactor contact pressure signals are very similar. However, the complexity of the measured contacts vibration is greater than the simulation results because the actual working condition is more complex. This result provides a theoretical foundation to the dynamic contacts contact pressure test.

  17. Adam Smith's invisible hand is unstable: physics and dynamics reasoning applied to economic theorizing

    Science.gov (United States)

    McCauley, Joseph L.

    2002-11-01

    Neo-classical economic theory is based on the postulated, nonempiric notion of utility. Neo-classical economists assume that prices, dynamics, and market equilibria are supposed to be derived from utility. The results are supposed to represent mathematically the stabilizing action of Adam Smith's invisible hand. In deterministic excess demand dynamics, however, a utility function generally does not exist mathematically due to nonintegrability. Price as a function of demand does not exist and all equilibria are unstable. Qualitatively, and empirically, the neo-classical prediction of price as a function of demand describes neither consumer nor trader demand. We also discuss five inconsistent definitions of equilibrium used in economics and finance, only one of which is correct, and then explain the fallacy in the economists’ notion of ‘temporary price equilibria’.

    Full Text Available Employees who abuse Internet privileges have become a major concern among today's employers. Employees misuse Internet at the workplace due to the overcrowded schedule, pressures at work, etc. Internet for private purposes is also used as a release or escape from work, escape from the reality of the workplace or due to poor organizational climate; it can be used as an efficient use of time at work but it can also be excessively used when the employees are not monitored. The survey results show that there is a correlation between Internet addiction and misuse of the Internet in the workplace. Electronic monitoring has a strong impact on the abuse of the Internet. More electronic monitoring will decrease the abuse of the internet services in the workplace and vice versa. Organizational climate, relations in the working organization, the Internet policy and demographic factors do not affect the abuse of Internet services in the workplace.

    Collaboration of professionals from diverse disciplines is required to address the multiple, complex issues and needs of community-dwelling elders who are abused or neglected. Reporting suspected elder abuse or neglect cases to Adult Protective Service (APS) agencies provides access to services that address the social, medical, and legal needs of elderly persons. A geriatric interdisciplinary team can provide a comprehensive medical, functional, and social assessment. Based on the findings from the assessment and in collaboration with the APS team, the intervention plan can be formulated. Some cases of elder abuse or neglect may require intervention from the criminal justice or the civil justice system for serious legal issues such as sexual assault, financial exploitation, or guardianship. Other resources, such as Area Agencies on Aging, local women's shelters, and The National Center for Elder Abuse, are available to help manage elder abuse and neglect cases in the community.

    Full Text Available According to the International Olympic Committee, the abuse of anabolic androgenic steroids (AASS is found in over 50% of positive doping tests. AASS abuse is not restricted to the organized sports andwidespread use. It remains as an unsolved public-health problem.Lower black market price, easier access to AASS, bodybuilding clubs and internet advertising are factors of this increasingly misuse. There is not real data about the prevalence of AASS abuse in various populations or countries, because most of athletes or students, due to their prohibition or ethical aspects do not admit to AASS abuse. Often they are aware of the risks of their choice and yet, are eager to put themselves at risk without deeper consideration. The abusers use them to improve their physical fitness and appearance.Present article has been collected to elucidate the risks and adverse effects of AASS and explanation of mechanisms of these events.

    To document quantity and cash value of underage and adult Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)-defined abusive and dependent drinking as well as underage drinking and adult DSM-IV-defined abusive and dependent drinking combined to the alcohol industry. Analysis of multiple cross-sectional national data sets. The 2001 National Household Survey on Drug Abuse, the 2001 Youth Risk Behavior Survey, the 2001 Behavioral Risk Factor Surveillance Survey, the 2000 US Census, the 2000 to 2001 National Epidemiological Survey on Alcohol and Related Conditions, and the 2001 Adams Business Research. A total of 260,580 persons aged 12 years and older across 4 data sources. Underage drinking or pathological drinking defined as meeting the DSM-IV criteria for abusive or dependent drinking. Total amount of alcohol consumed and the cash value for alcohol consumed among underage and adult drinkers with DSM-IV-defined alcohol abuse and dependence as well as all underage drinkers combined with adult drinkers with DSM-IV-defined alcohol abuse and dependence. The short-term cash value of underage drinking to the alcohol industry was 22.5 billion dollars in 2001-17.5% of total consumer expenditures for alcohol. The long-term commercial value of underage drinking is the contribution of underage drinking to maintaining consumption among adult drinkers with alcohol abuse and dependence, which was equal to at least 25.8 billion dollars in 2001. The combined value of illegal underage drinking and adult pathological drinking to the industry was at least 48.3 billion dollars, or 37.5% of consumer expenditures for alcohol, in 2001. Alternative estimates suggest that these costs may be closer to 62.9 billion dollars, or 48.8% of consumer expenditures for alcohol.

    Substance-involved females tend to have different clinical profiles than men (Adams, Leukefeld, & Peden, 2008 ); yet they do not appear to have worse treatment outcomes (Green, 2006 ; Hser, Huang, Teruya, & Anglin, 2003 ). As motivation for treatment is considered essential in the substance abuse treatment context (Cahill, Adinoff, Hosig, Muller, & Pulliam, 2003 ; Longshore & Teruya, 2006 ), it is possible that higher motivation among females could potentially counteract the negative effect of more risk factors. The purpose of the current study was to examine if females differ from males in their motivation for treatment using the Texas Christian University Motivation Form scales: desire for help, problem recognition, treatment readiness, pressure for treatment, and treatment needs; and whether factors predicting motivation for treatment differed between male and female participants of substance abuse treatment. The sample included 2,989 substance-involved males and 982 substance-involved females who were referred to substance abuse treatment through a case management program. Linear regression models predicting each motivation scale were analyzed, followed by gender-specific models. Overall, the results did not demonstrate a significant gender difference in the motivation scales. However, among male participants, the findings did show that Hispanic significantly predicted desire for help and alcohol as a primary drug of choice predicted treatment readiness. Findings suggest that motivation for treatment may be a gender-neutral construct, and that there is a need to better understand sociodemographic predictors of motivation.

    Full Text Available ABSTRACT:Drug abuse is the willful misuse of either licit or illicit drugs for the purpose of recreation, perceived necessity or convenience. Drug abuse is a more intense and often willful misuse of drugs often to the point of addiction. In the eastern world the incidence shows a decline or a static pattern but the number of drug addicts is still enormous.. The major drug of abuse are heroin and marijuana but designer drugs are shown to be on the increase. The aim of the study is to determine the ratio of the drug abuse in student. For this purpose we selected different institutions including “the university of Lahore”, “Forman Christian college”(private sector and Punjab university(Govt sector and conducted survey in 500 student. High proportion of students was found abusing drugs. From this study, we came across multiple factors which are the main cause of drug abuse in medical student including depression, anxiety, schizophrenia, as well as personality disorder like antisocial personality disorder. The most commonly abused drugs include stimulants, opioids, and benzodiazepines, antihistamines. Although survey have indicated high rate of illicit and prescription drugs misuse among college students, few have assessed the negative consequences, personel concerns, or interest in intervention for drugs use. Drug abuse although regarded as a personality disorder, may also be seen as worldwide epidemic with evolutionary genetic, physiology and environmental influences Controlling and affecting human behavior. Globally, the use has reached all time high. The study showed males are more drug abusers as compared to females. The drug abuse ratio in students of private sector is more as compared to Govt sector.

    To validate a locally developed chromatography-based method to monitor emerging drugs of abuse whilst performing regular drug testing in abusers. Cross-sectional study. Eleven regional hospitals, seven social service units, and a tertiary level clinical toxicology laboratory in Hong Kong. A total of 972 drug abusers and high-risk individuals were recruited from acute, rehabilitation, and high-risk settings between 1 November 2011 and 31 July 2013. A subset of the participants was of South Asian ethnicity. In total, 2000 urine or hair specimens were collected. Proof of concept that surveillance of emerging drugs of abuse can be performed whilst conducting routine drug of abuse testing in patients. The method was successfully applied to 2000 samples with three emerging drugs of abuse detected in five samples: PMMA (paramethoxymethamphetamine), TFMPP [1-(3-trifluoromethylphenyl)piperazine], and methcathinone. The method also detected conventional drugs of abuse, with codeine, methadone, heroin, methamphetamine, and ketamine being the most frequently detected drugs. Other findings included the observation that South Asians had significantly higher rates of using opiates such as heroin, methadone, and codeine; and that ketamine and cocaine had significantly higher detection rates in acute subjects compared with the rehabilitation population. This locally developed analytical method is a valid tool for simultaneous surveillance of emerging drugs of abuse and routine drug monitoring of patients at minimal additional cost and effort. Continued, proactive surveillance and early identification of emerging drugs will facilitate prompt clinical, social, and legislative management.

    Full Text Available Introduction: stroke in recreational substance users can be an indirect complication, like endocarditis and cardio embolism in parenteral drug users. With some drug like cocaine, stroke appear to be the result of a direct effect. In young subjects without other risk factors provide persuasive evidence for causality . OPIATES: Heroine is the most abused opiate drug, which is administered by injection, by snorting or by smoking. Stroke affects heroin users by diverse mechanisms,. Injectors are at risk of infections endocarditis, which carries risk for both ischemic and hemorrhagic stroke. Cerebral or subarachnoid hemorrhage usually occurs after rupture of a septic (mycotic aneurysm. Heroine users can are also at risk for hemorrhagic stroke secondary to liver failure with deranged clotting and to heroin nephropathy with uremia or malignant hypertension. In some heroin users the drug it self is directly causal due to vasculitis, hypersensitivity and immunologic changes. Embolization of foreign material to brain due to mixed of heroine with quinine can cause cerebral embolism. AMPHETAMINE AND other psychostimulants: In abuser of amphetamine hemorrhagic stroke can occur, oral, intravenous, nasal, and inhalational routes of administration have been reported. Most were chronic user, but in several patients, stroke followed a first exposure. Some of amphetamine induced intracranial hemorrhages are secondary to acute hypertension, some to cerebral vacuities, and some to a combination of two. Decongestants and diet pills: Phenylpropanolamine (PPA, an amphetamine – like drug, in decongestants and diet pills, induce acute hypertension, sever headache, psychiatric symptoms, seizures and hemorrhagic stroke.

    Full Text Available Child abuse is a pervasive social and medical problem that remains a major cause of disability and death among children. The annual incidence of abuse is estimated to be 15 to 42 cases per 1,000 children and appears to be increasing. Fractures are the second most common presentation of physical abuse after skin lesions, and approximately one third of abused children will eventually be seen by an orthopedic surgeon. We report a 7-month-old boy who was suspected to be abused. Our diagnosis was based on findings of multiple fractures, delay in seeking medical treatment and discrepancy between the history of illness and the clinical findings. He sustained multiple fractures in variety of healing, namely fractures on left supracondylar humeri, left radius and ulna, right radius and ulna, both femora, right tibia, and left tibia and fibula. Radiological examination was an important modality in revealing the possibility of abuse on this child. He had received medical treatment, protection, consultation team for the parents and an underway police investigation. (Med J Indones 2004; 13: 59-65 Keywords: child, abuse

    2017-12-18

    Abuse-deterrent opioid formulations have been suggested as one way to decrease the abuse, addiction, and overdose of orally prescribed opioids. Ten oral opioid formulations have received abuse-deterrent labeling by the U.S. Food and Drug Administration (FDA). Their properties consist of physical and/or chemical means by which the pills resist manipulation and create a barrier to unintended administration, such as chewing, nasal snorting, smoking, and intravenous injection. In this review, we describe the mechanisms of abuse-deterrent technology, the types of premarketing studies required for FDA approval, the pharmacology of the currently approved abuse-deterrent opioid formulations, and the evidence for and against their influence on opioid abuse. We conclude that there is currently insufficient evidence to indicate that the availability of abuse-deterrent opioid formulations has altered the trajectory of opioid overdose and addiction; however, postmarketing studies are in their infancy, and novel deterrent formulations are continually being developed and submitted for marketing approval.

    Catrocollastatin/vascular apoptosis-inducing protein (VAP)2B is a metalloproteinase from Crotalus atrox venom, possessing metalloproteinase/disintegrin/cysteine-rich (MDC) domains that bear the typical domain architecture of a disintegrin and metalloproteinase (ADAM)/adamalysin/reprolysin family proteins. Here we describe crystal structures of catrocollastatin/VAP2B in three different crystal forms, representing the first reported crystal structures of a member of the monomeric class of this family of proteins. The overall structures show good agreement with both monomers of atypical homodimeric VAP1. Comparison of the six catrocollastatin/VAP2B monomer structures and the structures of VAP1 reveals a dynamic, modular architecture that may be important for the functions of ADAM/adamalysin/reprolysin family proteins.

    To identify the causative mutation in a canine cone-rod dystrophy (crd3) that segregates as an adult onset disorder in the Glen of Imaal Terrier breed of dog. Glen of Imaal Terriers were ascertained for crd3 phenotype by clinical ophthalmoscopic examination, and in selected cases by electroretinography. Blood samples from affected cases and non-affected controls were collected and used, after DNA extraction, to undertake a genome-wide association study using Affymetrix Version 2 Canine single nucleotide polymorphism chips and 250K Sty Assay protocol. Positional candidate gene analysis was undertaken for genes identified within the peak-association signal region. Retinal morphology of selected crd3-affected dogs was evaluated by light and electron microscopy. A peak association signal exceeding genome-wide significance was identified on canine chromosome 16. Evaluation of genes in this region suggested A Disintegrin And Metalloprotease domain, family member 9 (ADAM9), identified concurrently elsewhere as the cause of human cone-rod dystrophy 9 (CORD9), as a strong positional candidate for canine crd3. Sequence analysis identified a large genomic deletion (over 20 kb) that removed exons 15 and 16 from the ADAM9 transcript, introduced a premature stop, and would remove critical domains from the encoded protein. Light and electron microscopy established that, as in ADAM9 knockout mice, the primary lesion in crd3 appears to be a failure of the apical microvilli of the retinal pigment epithelium to appropriately invest photoreceptor outer segments. By electroretinography, retinal function appears normal in very young crd3-affected dogs, but by 15 months of age, cone dysfunction is present. Subsequently, both rod and cone function degenerate. Identification of this ADAM9 deletion in crd3-affected dogs establishes this canine disease as orthologous to CORD9 in humans, and offers opportunities for further characterization of the disease process, and potential for genetic

It was used the Instrumental neutron activation analysis (AANI) with a flow of thermal neutrons of 8 x 10 13 and 5 x 10 13 n cm -2 s -1 . With the purpose of determining the concentration of these elements at level of traces; finding presence of 32 elements among which its were find elements in greater concentrations and others at level of traces. Of these 32 elements, five of anthropogenic origin were identified which its were: Cr, Co, Zn, As and Mn; but that whose concentration is very low, in comparison with the one reported in other places of the world. In this work there are presented the obtained results of the elementary analysis of this samples. (Author)

    Full Text Available Classical economists, John Stuart Mill included, based their theories on Adam Smith’s system. At some point, they labelled it as a "utilitarian" theory. However, Smith was non-utilitarian, perhaps even anti-utilitarian. One of the most amazing differences between classical economics versus Smithian theory consists of their concept of justice. Classical economics were based on a utilitarian concept; Smith criticizes the concept of utilitarian justice. Utility being a subjective picture, classical economists find it more difficult to draw limits to state intervention than Smith does. This paper compares Smith’s and John Stuart Mill’s concept of justice when they make the case for land tenure. Mill admits that society cannot properly be said to owe anything to the poor. However, not arguing from 'abstract rights,' but from 'utility' understood in its largest sense, Mill defended the nationalization of land. Mill was unable to draw any limits to state intervention. Conversely, Smith defended that justice is not a utilitarian concept. In this case, limits to state intervention are more easily drawn.
