    Unemployed individuals of pre-retirement age face significant challenges in finding a new job. This may be partly due to their lack of psychological readiness to go through a job interview. We view psychological readiness as one of the psychological attitude components. It is an active conscious readiness to interact with a certain aspect of reality, based on previously acquired experience. It includes a persons' special competence to manage their activities and cope with anxiety. We created Job Interview Simulation Training (JIST) - a computer-based simulator, which allowed unemployed job seekers to practice interviewing repeatedly in a stress-free environment. We hypothesized that completion of JIST would be related to increase in pre-retirement job seekers' psychological readiness for job interviewing in real life. Participants were randomized into control (n = 18) and experimental (n = 21) conditions. Both groups completed pre- and post-intervention job interview role-plays and self-reporting forms of psychological readiness for job interviewing. JIST consisted of 5 sessions of a simulated job interview, and the experimental group found it easy to use and navigate as well as helpful to prepare for interviewing. After finishing JIST-sessions the experimental group had significant decrease in heart rate during the post-intervention role-play and demonstrated significant increase in their self-rated psychological readiness, whereas the control group did not have changes in these variables. Future research may help clarify whether JIST is related to an increase in re-employment of pre-retirement job seekers.

    Full Text Available The study examined retirement adjustment of teacher-retirees in Osun State, and explored the interaction effects of pre-retirement guidance and family in-volvement on retirement adjustment. Exposit-facto design was used. The population comprised retirees from public, civil and private establishments from which 122 teacher-retirees were selected using a multi-stage sampling technique. An instrument: Family Involvement, Pre-retirement Guidance and Retirement Adjustment Questionnaire was used for data collection. Three research questions and three hypotheses guided the study. Data were analyzed using descriptive and inferential statistics. Results revealed that retirees in Osun State are not optimally adjusted, and positive significant interaction effect was found between family involvement and pre-retirement guidance on retirees adjustment, among others. Appropriate policy implications are outlined.

    BACKGROUND Home blood pressure (HBP) is prognostically superior to office BP (OBP) and similar to ambulatory BP measurements. We determined the prevalence of hypertension using HBP with telemedical data transmission in the municipality of Holstebro, Denmark (57,000 citizens). METHODS Using the Civil Registration System, we invited citizens aged 5564 years to have their OBP and HBP measured using telemedical data transmission. Elevated OBP was defined as ≥140/90mm Hg. HBP was measured 3 times daily on 3 consecutive days with 3 measurements on each occasion. HBP was the mean of all measurements on day 1 and 3, and hypertension was defined as ≥135/85mm Hg. RESULTS We included 3,102 citizens who had performed at least 12 HBP measurements during day 2 and 3. Group 1: (n = 1,464, 47%) had both normal OBP and HBP. Group 2: (n = 838, 27%) had both elevated OBP and HBP indicating persistent hypertension. Group 3: (n = 560, 18%) had elevated OBP and normal HBP indicating white coat hypertension (WCH). Group 4: (n = 240, 8%) had normal OBP and elevated HBP indicating masked hypertension (MH). Thus, 1,078 (35%, groups 2 and 4) were untreated or insufficiently treated. Awareness of hypertension was registered in 950 patients (31%) and of these 49% had a normal HBP. CONCLUSIONS This is the first large-scale study to eliminate completely reporting bias by using telemedical transmission of BP data. One third of citizens in the age group 5564 years had an abnormally high HBP, and one fourth either had WCH or MH.

    people in Korea take far more of interests in the nuclear power and whether they are well prepared in the lack of professional human resources in it in the foreseeable future. It is not only personal concern anymore, but also national concern. In particular, retirement of the experts in nuclear field is likely to lose our competitiveness in the world. It is urgent for the government and institutions in Korea to develop and implement educational programs to secure talented new workers in the field. This study analyzes the cases of development and application of pre-retirement education program of professional talent for nuclear R and D and then, develops programs to help nuclear experts retire. In the aging society, the retirement of nuclear experts is a national issue that can't be held off rather than each worker's problem. There are people at the heart of nuclear power. This is because they do all the things like nuclear research and development, and construction. Therefore, it is important to nurture and manage nuclear experts to ensure the sustainable development of nuclear with safety. This program could be also a part of it. KAERI is the organization that represents domestic nuclear research, and it is their urgent task to prepare for aging.

    Full Text Available To examine the association of employment status and characteristics with prevalent and incident memory complaints (MC in 55-64-year-olds.Subjects were participants of the Longitudinal Aging Study Amsterdam (LASA. Respondents with baseline data were selected to examine the association of employment status (n = 1525 and employment characteristics (n = 1071 with prevalent MC (i.e., MC at baseline. Respondents without MC at baseline were selected to examine the association of employment (n = 526 and employment characteristics (n = 379; working hours, job prestige, job level, psychological job demands, iso-strain with incident MC (i.e., no MC at baseline and MC at three-year follow-up. Associations were adjusted for relevant covariates (demographics, memory performance, physical health, mental health, personality traits. Logistic regression was applied. Data were weighed according to gender and age of the Dutch population.At baseline 20.5% reported MC. At three-year follow-up, 15.4% had incident MC. No associations were found between employment status and MC. Adjusted analysis revealed that individuals with high occupational cognitive demands were more likely to have prevalent MC.Middle-aged workers are equally as likely to experience MC as non-working age-peers. Among workers, those with cognitively demanding work were more likely to experience MC, independent of memory performance. Memory decline due to ageing may be noticed sooner in 55-64-year-olds performing cognitively demanding work.

To study the prevalence of ECG ischemic disorders assessed by theMinnesota code on a sample of people over 50 years, depending on gender, age and employment.Material and methods. The results of a survey of a representative sample of the unorganized population of 13 regions, participants of the ESSE-RF program in 2012-2014, were included into the study (n=8334 people; men - 2784, women - 5550. Analysis of the prevalence of ECG changes was carried out by the Minnesota code in groups of 50-54, 55-59 and 60-64 years old, depending on gender and employment (employed and unemployed.Results. Pathological changes were recorded on the ECG more often in men compared to women – Q(QS-wave (5% vs 1.9%, atrial fibrillation (2.1% vs 0.8%; p<0.01, conduction abnormalities (2.7% vs 1.6%; p<0.002 with a maximum in 60-64 years old (4.4% vs 2.6%; p<0.01, respectively. ST segment depression and the T wave abnormalities (myocardial ischemia occurred more often in women than in men (6.9% vs 5.1%, respectively; p<0.001, with a significant increase of these changes in women after 60 years old. The prevalence of ECG abnormalities increases with age. Significant rise of ECG-changes prevalence was found in men at the age of 55-59 years (pathological QQS, myocardial ischemia, left ventricular hypertrophy; and in women – at 60-64 years (myocardial ischemia, atrial fibrillation, conduction abnormalities. Almost two-fold increase in the incidence of arrhythmias and conduction abnormalities was found in men and women aged 60-64 years, regardless of employment status.Conclusion. Given the poor prognosis of ischemic ECG abnormalities, even their low prevalence indicates to unfavorable epidemiological situation among people around retirement age (55-64. These results emphasize the need for practitioners to careful attention to the ECG-abnormalities with poor prognosis in patients pre-retirement and retirement age.

    Objective: To determine the optimal contrast protocols for 64-slice spiral CT coronary angiography in order to reduce the volume of contrast injection. Methods: One hundred fifty patients scheduled to undergo 64-slice spiral CT coronary angiography were prospectively randomized into the following five groups with different injection protocols: group 1: uniphasic injection without a flush; group 2: biphasic injection with a flush; group 3, group 4 and group 5 : triphasic injection with a diluted contrast material with 3:7, 5:5, 7:3 contrast/saline ratio respectively. Attenuation was measured in the right atrium, right ventricle, left atrium, left ventricle, ascending aorta, right coronary artery and left coronary artery and analyzed with single factor variance test (ANOVA). The quality of the coronary artery images was evaluated and compared using person Chi-Square. Results: The total contrast material volume were (67.0±5.3) ml, (59.9±4.9) ml, (62.9±3.2) ml, (69.2±5.7) ml and (70.9±4.6) ml in five groups respectively (F=27.43, P 2 =18.81, P 2 =31.44, P<0.01). The artifacts in the superior vena cava in group 1 was the most, and in group 2 was the least. The mean enhancement values of right and left coronary arteries in group 2 were significantly greater than those in other groups (F=2.47 and 4.10, P<0.05). The visualization of both left ventricle and right ventricle cavities was the best in group 3. Conclusion: Biphasic injection and triphasic injection are better than uniphasic injection for 64-slice spiral CT coronary angiography and triphasic injection is better than biphasic injection for the visualization of both left ventricle and right ventricle cavities.

The latent "calmodulin kinase" activity of CK2 can also be specifically unmasked by a peptide (alpha[66-86]) reproducing a basic insert of the catalytic subunit. This effect is reversed by equimolar addition of a peptide (beta[55-71]) including the 55-64 acidic stretch of the beta......-subunit. Comparable polylysine stimulation was observed with the holoenzymes reconstituted with either beta wt or the beta mutants capable of assembling with the alpha-subunit, with the notable exception of those bearing Ala substitutions for acidic residues at positions 55, 57, and 59-61. These were nearly...

    Recent national trends show decelerating declines in heart disease mortality, especially among younger adults. National trends may mask variation by geography and age. We examined recent county-level trends in heart disease mortality by age group. Using a Bayesian statistical model and National Vital Statistics Systems data, we estimated overall rates and percent change in heart disease mortality from 2010 through 2015 for four age groups (35-44, 45-54, 55-64, and 65-74 years) in 3098 US counties. Nationally, heart disease mortality declined in every age group except ages 55-64 years. County-level trends by age group showed geographically widespread increases, with 52.3%, 58.5%, 69.1%, and 42.0% of counties experiencing increases with median percent changes of 0.6%, 2.2%, 4.6%, and -1.5% for ages 35-44, 45-54, 55-64, and 65-74 years, respectively. Increases were more likely in counties with initially high heart disease mortality and outside large metropolitan areas. Recent national trends have masked local increases in heart disease mortality. These increases, especially among adults younger than age 65 years, represent challenges to communities across the country. Reversing these trends may require intensification of primary and secondary prevention-focusing policies, strategies, and interventions on younger populations, especially those living in less urban counties.

    The potential dynamics of cognitive impairment in schizophrenia is discussed in the literature of the field. Recent publications suggest modest changes in level of cognitive impairment after first psychotic episode. Present article attempts to explore cognitive differences between patients and controls across age groups and differences between age groups in clinical group. One hundred and twenty-eight hospitalized patients with schizophrenia (64 women and 64 men) and 68 individuals from the control group (32 women and 32 men) aged 18-55 years were examined. The patients were divided into age groups (18-25, 26-35, 36-45, 46-55). Both groups were examined using Wisconsin Card Sorting Test, Rey Auditory Verbal Learning Test, Rey Osterrieth Complex Figure Test, Trail Making Test (A and B), Stroop Test, verbal fluency test and Wechsler digit span. Patients with schizophrenia obtained significantly lower scores versus the control group in regard to all the measured cognitive functions (Mann-Whitney U; p age groups, however, statistically important impairment in executive functions (WCST) were present only in "older" groups. Patients with schizophrenia obtained less favourable results than the control group in all age groups. Deficits regarding executive functions do not seem to be at a significant level among the youngest group, whereas they are more noticeable in the group of 46-55-year-olds. Executive functions are significantly lowered in the group aged 36-45 in comparison to the "younger" groups. The level of cognitive functions shows a mild exacerbation in connection with age, whereas cognitive rigidity proved to be related to the number of years spent without hospital treatment.

    Despite nearly universal insurance coverage for older Americans over the age of 65, the preretirement age cohort is susceptible to gaps in coverage. Related to the Patient Protection and Affordable Care Act (ACA), this study investigated heterogeneity in insurance status for preretirement Asian immigrants by examining the interacting effects of Asian ethnicity and employment type, which is a major factor that determines an individual's insurance status in the U.S. Data from the 2009 California Health Interview Survey, which included 1,024 Asians between the ages of 50 and 64, were analyzed. Our findings indicate significant moderating effects of employment type and Asian ethnicity. However, regardless of employment type, Koreans had the highest rate of being uninsured. To effectively reach the ACA's goal of reducing the number of uninsured individuals, targeted interventions specific to Asian subgroups are essential. © The Author(s) 2013.

    Reliable production of copper-64 ({sup 64}Cu) was achieved by irradiating enriched nickel-64 ({sup 64}Ni, >94.8%) in an IBA 18/9 cyclotron. Nickel-64 (19.1 {+-} 3.0 mg) was electroplated onto an Au disc (125{mu}m Multiplication-Sign 15mm). Targets were irradiated with 11.7 MeV protons for 2 hours at 40{mu}A. Copper isotopes ({sup 60,61,62,64}Cu) were separated from target nickel and cobalt isotopes ({sup 55,57,61}Co) using a single ion exchange column, eluted with varying concentration of low HCl alcohol solutions. The {sup 64}Ni target material was recovered and reused. The {sup 64}Cu production rate was 1.46{+-}0.3MBq/{mu}A.hr/mg{sup 64}Ni(n = 10) (with a maximum of 2.6GBq of {sup 64}Cu isolated after 2hr irradiation at 40uA. Radionuclidic purity of the {sup 64}Cu was 98.7 {+-} 1.6 % at end of separation. Cu content was < 6mg/L (n = 21).

    Full Text Available Maintaining grey matter within the hippocampus is important for healthy cognition. Playing 3D-platform video games has previously been shown to promote grey matter in the hippocampus in younger adults. In the current study, we tested the impact of 3D-platform video game training (i.e., Super Mario 64 on grey matter in the hippocampus, cerebellum, and the dorsolateral prefrontal cortex (DLPFC of older adults. Older adults who were 55 to 75 years of age were randomized into three groups. The video game experimental group (VID; n = 8 engaged in a 3D-platform video game training over a period of 6 months. Additionally, an active control group took a series of self-directed, computerized music (piano lessons (MUS; n = 12, while a no-contact control group did not engage in any intervention (CON; n = 13. After training, a within-subject increase in grey matter within the hippocampus was significant only in the VID training group, replicating results observed in younger adults. Active control MUS training did, however, lead to a within-subject increase in the DLPFC, while both the VID and MUS training produced growth in the cerebellum. In contrast, the CON group displayed significant grey matter loss in the hippocampus, cerebellum and the DLPFC.

    We aim to develop robust estimates of disability-free life expectancy (DFLE) and healthy life expectancy (HLE) for ethnic groups in England and Wales in 2001 and to examine observed variations across ethnic groups. DFLE and HLE by age and gender for five-year age groups were computed for 16 ethnic groups by combining the 2001 Census data on ethnicity, self-reported limiting long-term illness and self-rated health using mortality by ethnic group estimated by two methods: the Standardised Illness Ratio (SIR) method and the Geographically Weighted Method (GWM). The SIR and GWM methods differed somewhat in their estimates of life expectancy (LE) at birth but produced very similar estimates of DFLE and HLE by ethnic group. For the more conservative method (GWM), the range in DFLE at birth was 10.5 years for men and 11.9 years for women, double that in LE. DFLE at birth was highest for Chinese men (64.7 years, 95% CI 64.0-65.3) and women (67.0 years, 95% CI 66.4-67.6). Over half of the ethnic minority groups (men: 10; women: 9) had significantly lower DFLE at birth than White British men (61.7 years, 95% CI 61.7-61.7) or women (64.1 years, 95% CI 64.1-64.2), mostly the Black, Asian and mixed ethnic groups. The lowest DFLE observed was for Bangladeshi men (54.3 years, 95% CI 53.7-54.8) and Pakistani women (55.1 years, 95% CI 54.8-55.4). Notable were Indian women whose LE was similar to White British women but who had 4.3 years less disability-free (95% CI 4.0-4.6). Inequalities in DFLE between ethnic groups are large and exceed those in LE. Moreover, certain ethnic groups have a larger burden of disability that does not seem to be associated with shorter LE. With the increasing population of the non-White British community, it is essential to be able to identify the ethnic groups at higher risk of disability, in order to target appropriate interventions.

    Full Text Available DNS64 and NAT64 are IPv6 transition technologies enabling IPv6 only clients to communicate with IPv4 only servers. Mtd64-ng is a novel DNS64 implementation, being a successor of MTD64. In this paper, the performance of mtd64-ng is compared with that of MTD64 and BIND. The details of the measurements are fully disclosed. It is found that under heavy load conditions mtd64-ng can answer six times as many “AAAA” record requests per second than BIND. Mtd64-ng fixed two issues of MTD64 and also outperformed its predecessor by answering 46% more “AAAA” record requests per second under heavy load conditions.

    AbstractBackgroundSeveral studies have shown the influence of the perceptions of aging on the cognitive functioning and the mental and physical health of older people. These relationships have not to date been studied in France where validated instruments are lacking. The primary objective of this study was to validate a French-language version of the Aging Perceptions Questionnaire (APQ) in the French general population aged 65 and over. The secondary objective was to study the stability of the dimensions of this instrument among participants aged 55 to 64.MethodsThe study was proposed to the cohort of the Observatoire Régional du Vieillissement (OPREVI) (observatory of aging), located in a small town in Poitou-Charentes (western France). An anonymous questionnaire including the APQ was sent by mail to inhabitants aged 55 and over. The original English language APQ was described with adults aged 65 and older. It has 32 items distributed on 7 dimensions: timeline chronic and cyclical, positive and negative consequences, positive and negative control and emotional representations.Results656 adults participated in this survey (286 men, 370 women). Among those aged 65 and over (n = 394), the seven-factor structure estimated by confirmatory factor analysis was coherent with original findings. Internal consistency as evaluated by Cronbach alpha, was between 0.83 for consequences negative and 0.52 for control negative. Several dimensions were strongly correlated. Among participants aged 55 to 64 (n = 262), the same factorial model yielded an acceptable fit. Multi-group confirmatory factor analysis concluded to approximate factorial invariance between the two age groups with a null delta in comparative fit index.ConclusionThis study among French people aged 65 and over, added further evidence of the multidimensional structure of the French version of the APQ which is superimposed to the dimensions of the original Irish version. The same factorial structure

    The fifth pre-retirement seminar has been a great success. The various sessions covered questions relating to rules and regulations, as well as financial and health issues, health insurance, residence permits and the psychological aspects of retirement. You will no doubt have noticed that the car parks near the Main Building were particularly full last week. In fact it was almost impossible to find a parking spot. A prestigious speaker? A sensational lecture series? Nothing of the sort. It was all due to the pre-retirement seminar, the fifth of its kind since 1993, which never fails to be a success. 'We sent out a thousand invitations to CERN staff aged 55 and above and received 500 positive replies' says William Blair, who has been organising the seminars for the Human Resources (HR) Division for the last eight years in collaboration with the CERN Pensioners Association and the Staff Association. The Main Auditorium was not big enough to accommodate everyone and the discussions also had to be retransmitted l...

  16. CYP2D6*4 polymorphism is associated with statin-induced muscle effects.

    Statin use is associated with a variety of overtly related muscle symptoms including muscle pain, myalgia, creatine kinase elevations without pain with myolysis and myositis (rhabdomyolysis), a potentially fatal side effect that led to the withdrawal of cerivastatin in 2001. Unintended drug response phenotypes have an impact on patient compliance and sometimes patient health and the assessment of risk on an individual basis could enhance therapeutic benefit. We therefore investigated whether common single nucleotide polymorphisms were associated with the expression of broadly grouped atorvastatin-induced muscle events in a case-control study (n=263 samples, n=388 SNPs). Of a number of associations identified in a discovery sample (51 atorvastatin-induced muscle and 55 normal) only those corresponding to the CYP2D6*4 allele were significantly associated in the sample (24 atorvastatin-induced muscle and 133 normal) (Discovery P=0.004, odds ratio=3.6; Validation P=0.036, odds ratio=2.7; total P=0.001, odds ratio=2.5). The frequency of the CYP2D6*4 allele was about 50% in atorvastatin-induced muscle patients but only 28% in controls, similar to that of other patient types (28.5%). The association was independent of various demographic variables and not explained by gross demographic, clinical or population-structure differences among cases and controls. Surprisingly, the CYP2D6*4 allele appeared similarly distributed among controls and patients expressing simvastatin-induced muscle events (n=169, frequency in case participants=49.2%, P=0.067, odds ratio=1.7). Our results suggest that the CYP2D6*4 allele is associated with broadly related muscle events caused by at least two structurally dissimilar HMG-CoA reductase inhibitors, and as such, may have implications for a better understanding of this statin-wide phenomena.

    Full Text Available It is often suggested that the approach to IPv6 transition is dual-stack deployment; however, it is not feasible in certain environments. As Network Address Translation -- Protocol Translation (NAT-PT has been deprecated, stateful NAT64 and DNS64 RFCs have been published, supporting only IPv6-to-IPv4 translation scenario. Now the question of usability in the real world arises. In this paper, we systematically test a number of widely used application-layer network protocols to find out how well they traverse Ecdysis, the first open source stateful NAT64 and DNS64 implementation. We practically evaluated 18 popular protocols, among them HTTP, RDP, MSNP, and IMAP, and discuss the shortcomings of such translations that might not be apparent at first sight.

    Since many years, the SL/BT group has developed specific G-64 hardware modules for the control of the fast pulsed magnets. Up to now, the integration of these modules into the accelerator control system has been done using a MIL1553 fieldbus in command/response mode connected to a LynxOS front-end. In 1996 and 1998, recommendations for the use of industrial fieldbuses and programmable logic controllers were issued at CERN. In order to integrate the existing G-64 hardware into this environment based on industrial components, an interface between the G-64 bus and the PROFIBUS-DP fieldbus has been developed. This interface is based on a modular and open hardware architecture with on one side an off-the-shelf industrial, fieldbus independent, interface and on the other side a FPGA (Field Programmable Gate Array). Required functionality has been implemented within the FPGA with VHDL (Very high-speed integrated circuit Hardware Description Language).

    Full Text Available In the current phase of the IPv6 transition, it is a typical situation that IPv6 only clients should be enabled to communicate with IPv4 only servers. The DNS64+NAT64 tool suite is an excellent solution to this problem. Although several free software DNS64 implementations exist, we point out that there is room for further high performance and computation efficient multithreaded DNS64 implementations. MTD64 was designed to be able to utilize several CPU cores. Whereas MTD64 outperformed BIND more than five times, two critical issues (memory leaking and potential vulnerability to DoS attacks were identified. Therefore MTD64 was redesigned under a new name: mtd64-ng (not capitalized. This paper is about the design, implementation and initial performance estimation of mtd64-ng. The usage of object oriented decomposition and the RAII (Resource Acquisition Is Initialization idiom ensures that raw, sensitive resources (e.g. memory, sockets are always released and it greatly simplifies exception handling. Using the new features of the C++11 standard enabled us to write more efficient and better readable code. The performance of mtd64-ng is compared to that of BIND and MTD64 and it is found that mtd64-ng outperforms even its predecessor, MTD64.

  7. FEMINISATION OF POVERTY AND THE BURDEN OF THE OLDER WOMAN: BALANCING WORK AND FAMILY IN PRE-RETIREMENT LIFE AND THE ACCUMULATED DISADVANTAGE FOR OLDER WOMEN IN ALBANIA

    Full Text Available The number one goal of the United Nations on the millennium development agenda is the eradication of extreme poverty and hunger. But poverty, as other problems, reveals more when examined from a multi-dimensional and dynamic perspective, and gender-sensitive lenses can make a major contribution. The “feminisation of poverty” (ranging from a higher incidence of women among the poor to poverty in terms of a lack of or limited choices has been documented by research throughout the world as a result of the interaction of three main factors: the introduction of gender elements in the research and literature on poverty; the high incidence of specific groups of women under the poverty line; and the mismatch between women’s life cycles and policies in place. This paper provides additional evidence on the “feminisation of poverty” by looking at the case of Albania as representative of an under-researched category of countries emerging as new democracies in the 1990s. The argument put forward is that the intersectionality of gender and age results in a larger burden of poverty among older women. To support the argument, the paper goes beyond the limited official poverty statistics in Albania by looking at the economic activity of women and men, analysing the work-family reconciliation policy framework in Albania, and providing evidence of the work-family tension based on secondary data analysis. It is found that combining work and family life in the pre-retirement period in Albania presents more disadvantages for women than for men, leading to the  “feminisation of poverty” in the post-retirement stages in life. This is then fuelling a new trend for unemployed women and retired women to work as informal caregivers, filling the deficiency in care for the eldest and youngest people in their own families or in the families of wealthier women. The policy logic and respective provisions in Albania, at best, are not discouraging the phenomenon.

    Full Text Available Abstract Background Members of the Baculoviridae encode two types of proteins that mediate virus:cell membrane fusion and penetration into the host cell. Alignments of primary amino acid sequences indicate that baculovirus fusion proteins of group I nucleopolyhedroviruses (NPV form the GP64 superfamily. The structure of these viral penetrenes has not been determined. The GP64 superfamily includes the glycoprotein (GP encoded by members of the Thogotovirus genus of the Orthomyxoviridae. The entry proteins of other baculoviruses, group II NPV and granuloviruses, are class I penetrenes. Results Class III penetrenes encoded by members of the Rhabdoviridae and Herpesviridae have an internal fusion domain comprised of beta sheets, other beta sheet domains, an extended alpha helical domain, a membrane proximal stem domain and a carboxyl terminal anchor. Similar sequences and structural/functional motifs that characterize class III penetrenes are located collinearly in GP64 of group I baculoviruses and related glycoproteins encoded by thogotoviruses. Structural models based on a prototypic class III penetrene, vesicular stomatitis virus glycoprotein (VSV G, were established for Thogoto virus (THOV GP and Autographa california multiple NPV (AcMNPV GP64 demonstrating feasible cysteine linkages. Glycosylation sites in THOV GP and AcMNPV GP64 appear in similar model locations to the two glycosylation sites of VSV G. Conclusion These results suggest that proteins in the GP64 superfamily are class III penetrenes.

    Full Text Available AIM:To observe the expression of tumor necrosis factor- alpha(TNF-αand its receptor I(P55in different pterygium and discuss the role of TNF-α and receptor I(P55in pterygium.METHODS: Immunohistochemistical staining method(PVwas adopted to detect the expression of TNF-α and receptor I in pterygium(72 eyesand para-pterygium conjunctival tissue(30 eyes. The relationship between the expression and clinical-pathological parameters was also analyzed. RESULTS: The positive rates of TNF-α were 65.3%(47/72, 26.7%(8/30in pterygium and para-pterygium conjunctival tissue. The positive expression of TNF-α had statistic difference between the two groups(χ2=12.706, Pχ2=13.875, Pχ2=6.547, P=0.011. There had no statistically significance of the expression intensity between the two groups(F=1.288, P=0.393; the positive rate in advanced pterygium group was higher than quiescent pterygium group(χ2=4.082, P=0.043. The expression intensity had no statistically significance between the two groups(F=0.489, P=0.708. The positive rate of P55 in recurrent pterygium group was higher than primary pterygium group(χ2=9.907, P=0.002. There had no statistically significance of the two group's expression intensity(F=1.175, P=0.424; the positive rate in advanced pterygium group was higher than in quiescent pterygium group(χ2=11.140, P=0.001. The expression intensity had no statistically significance between the two groups(F=0.665, P=0.621. CONCLUSION:The expression of TNF-α and P55 are changing according to the development of clinical staging and onset. The expression of TNF-α and P55 may be related to clinical classification, staging and patient's working conditions of pterygium. There has no significant difference expression intensity of TNF-α and P55 in clinical staging and onset of pterygium.

    A 1-by-64 multimode interference power splitter in SiO2 has been designed for use in fiber-optics communication systems. The splitter exhibits a minimum loss of 0.5 db and a uniformity of 1.7 dB at a wavelength of 1.55 μm. The polarization sensitivity is below 0.14 dB, the reflection level below...... -55 dB, and the optical bandwidth 30 nm. The fabrication tolerances are ±0.1 mm on the length and ±3.5 μm on the width of the multimode section of the splitter. In comparison with a branching-type splitter it is found that the designed device is approximately 30% shorter than the branching-type device...

    Fish otoliths are calcium carbonate biominerals that are involved in hearing and balance sensing. An organic matrix plays a crucial role in their formation. Otolith matrix macromolecule-64 (OMM-64) is a highly acidic, calcium-binding protein (CBP) found in rainbow trout otoliths. It is a component of high-molecular-weight aggregates, which influence the size, shape and polymorph of calcium carbonate in vitro. In this study, a protocol for the efficient expression and purification of OMM-64 was developed. For the first time, the complete structural characteristics of OMM-64 were described. Various biophysical methods were combined to show that OMM-64 occurs as an intrinsically disordered monomer. Under denaturing conditions (pH, temperature) OMM-64 exhibits folding propensity. It was determined that OMM-64 binds approximately 61 calcium ions with millimolar affinity. The folding-unfolding experiments showed that calcium ions induced the collapse of OMM-64. The effect of other counter ions present in trout endolymph on OMM-64 conformational changes was studied. The significance of disordered properties of OMM-64 and the possible function of this protein is discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Objective: To study the prevalence of high-risk HPV (HR HPV) in women who accepted cervical cancer screening in Beijing and its distribution in cervical precancerous lesions. Methods: From January 2014 to March 2015, all women aged 35-64 years old and received free screening in institutions of cervical cancer in Beijing were recruited. Stratified cluster random sampling method was used in selecting 31 091 women for gynecological examination and genotyping of HR-HPV. Those positive for HR-HPV (except for HPV 16/18) were examined for cervical cell. For those atypical squamous cells of uncertain significance (ASCUS) and above, who were positive for HPV 16/18 and with uncertain results for cervical cell, were transferred for colposcopy examination. For those with suspicious or abnormal results for colposcopy, were transferred for histopathology. The prevalence of HR-HPV, cervical cancer and precancerous lesions among the participants were analyzed. Results: Totally 31 091 women aged from 35-year-old to 64-year-old, with 44.3% (13 780 women) in the 35-49 age group and 55.7% (17 311 women) in the 50-64 age group. 66.1% (20 536 women) were rural women. The infection rate of HR-HPV was 7.4%(2 305 cases) among the women. High-risk infection rates of HPV except HPV 16/18 were 5.7% (1 758 cases), and multi-infection rate was 1.5% (477 cases). The highest infection rate was 7.9% (1 044 cases) among the 45-49 year-old and 50-54 year-old age groups (χ(2)=14.07, P= 0.015). The rate in rural women was significantly higher than that of the urban women (6.2%, 507 cases; 7.9%, 1 798 cases) (χ(2)=25.75, Page group.

    Full Text Available Objective: The aim of this study is to investigate if neutrophil CD64 expression in febrile neutropenia patients could be used as an early indicator of bacteremia. Materials and Methods: All consecutive patients older than 18 years of age who had developed febrile neutropenia episodes due to hematological malignancies were included in the study. Those patients who had significant growth in their blood cultures constituted the case group, while those who had febrile neutropenia without any growth in their cultures and who did not have any documented infections formed the control group. Blood culture bottles were incubated in the Bact ALERT 3D system (bioMerieux, France, identification and susceptibility testing were performed using an automated broth microdilution method (VITEK 2, bioMerieux, and CD64 expression analysis was performed by the flow cytometry method. C-reactive protein (CRP was measured by turbidimetric methods (Biosystems, Spain and erythrocyte sedimentation rate (ESR was measured by the Wintrobe method. Results: In total, we prospectively evaluated 31 febrile episodes. The case group consisted of 17 patients while the control group included 14 patients. CD64 was found on neutrophils of the case group patients with a mean count of 8006 molecules/cell and of control group with a mean count of 2786 molecules/cell. CD64 levels of the case group were significantly higher than those of the control group (p=0.005. In the differentiation of the case group from the control group, a 2500 cut-off value for CD64 had significant [AUC=0.792 (0.619-0.965] predictive value (p=0.001. In the prediction of patients with a 2500 cut-off value for CD64, sensitivity was 94.1%, positive predictive value was 76.2%, specificity was 64.3%, and negative predictive value was 90.0%. CRP levels and ESR values did not differ significantly between the groups (p=0.005. Conclusion: Neutrophil CD64 expression could be a good predictor as an immune parameter with

    Postacute myocardial infarction (AMI) readmissions are common among Medicare beneficiaries (≥65 years) and are associated with significant resource utilization. However, patterns of AMI readmissions for younger age groups in the United States are not known. In the Nationwide Readmissions Database, a nationally representative all-payer database of inpatient hospitalizations, we identified 212,171 index AMI hospitalizations in January to November 2013, weighted to represent 478,247 hospitalizations nationally (mean age 66.9 years, 38% women, 29% low income). This included 26,516 cases in the 18 to 44 age group, 183,703 in the 45 to 64 age group, and 268,027 in the ≥65 age group. The overall 30-day readmission rate was 14.5% and varied across age groups (9.7% [18 to 44], 11.2% [45 to 64], and 17.3% [≥65]). The cumulative cost of 30-day readmissions was $1.1 billion, of which $365 million was spent on those age. In multivariable hierarchical models, the risk of readmission was higher in women and in low-income patients, but the effect varied by age (p value for age-gender and age-income interactions age groups. Further, patients in all age groups continue to have a high hospitalization burden beyond the typical 30-day readmission period, with an overall 24% post-AMI 90-day readmission rate. In conclusion, readmissions in young and middle-aged AMI survivors pose a substantial burden on patients and on U.S. health-care resources. Women and low-income patients with AMI, particularly those in younger age groups, are more frequently readmitted, and readmissions continue to burden the health-care system beyond the typical 30-day window. Future investigations would need to be targeted toward a better understanding and improvement of the rehospitalization burden for vulnerable patient groups. Copyright © 2017 Elsevier Inc.

    Full Text Available Newborn chicks are susceptible to Salmonella enterica serovar Enteritidis (SE. The objective of this study was to evaluate the effect of Lactobacillus probiotic isolated from chicken feces on heterophil phagocytosis in broiler chicks. A total of 150 newborn broiler chicks were divided into 5 groups (30 chicks per group as follows: group 1 (normal control, given feed and water only, group 2 (positive control given feed, water and SE infection, group 3 (L61 treated given feed, water, SE infection followed by Lactobacillus salivarius L61 treatment, group 4 (L55 treated given feed, water, SE infection followed by L. salivarius L55 treatment, and group 5 given feed, water, SE infection followed by L. salivarius L61 + L55 combination treatment. After SE infection, L. salivarius treatment lasted for 7 days. The results showed that L. salivarius L61 and L. salivarius L55 treatment, either alone or combination of both, increased the survival rate after SE infection, and upregulated heterophil phagocytosis and phagocytic index (PI. Conversely, chick groups treated with Lactobacillus showed lower SE recovery rate from cecal tonsils than that of the positive control group. The PI values of the chicken group with SE infection, followed by the combination of L. salivarius L61 and L. salivarius L55 were the highest as compared to either positive control or normal control group. Two Lactobacillus strains supplementation group showed significantly (p<0.05 higher PI value at 48 h than 24 h after treatment.

    Aim of the study β-thalassaemia (β-Thal) is considered a severe, progressive haemolytic anaemia, which needs regular blood transfusions for life expectancy. Complement-mediated erythrocyte destruction can cause both intravascular and extravascular haemolysis. Complement regulatory proteins protect cells from such effects of the complement system. We aimed to perform quantitative analysis of membrane-bound complement regulators, CD55 (decay accelerating factor – DAF), CD35 (complement receptor type 1 – CR1), and CD59 (membrane attack complex inhibitory factor – MACIF) on peripheral red blood cells by flow cytometry. Material and methods The present study was carried out on 47 β-thalassemia major (β-TM) patients, 20 β-thalassaemia intermedia (β-TI) patients, and 17 healthy volunteers as control subjects. Results CD55 levels of β-TM patients (58.64 ±17.06%) were significantly decreased compared to β-TI patients (83.34 ±13.82%) and healthy controls (88.57 ±11.69%) (p < 0.01). CD59 levels of β-TM patients were not significantly different than β-TI patients and controls, but CD35 levels were significantly lower in the β-TM patients (3.56 ±4.87%) and β-TI patients (12.48 ±9.19%) than in the control group (39.98 ±15.01%) (p < 0.01). Conclusions Low levels of CD55 and CD35 in thalassaemia major patients indicates a role for them in the aetiopathogenesis of haemolysis in this disease, and also this defect in a complement system may be responsible for the chronic complications seen in these patients.

    2015-01-01

    What is the socially optimal level of liquidity in a retirement savings system? Liquid retirement savings are desirable because liquidity enables agents to flexibly respond to pre-retirement events that raise the marginal utility of consumption. On the other hand, pre-retirement liquidity is undesirable when it leads to under-saving arising from, for example, planning mistakes or self-control problems. This paper compares the liquidity that six developed economies have built into their employ...

    2016-07-01

    In this paper, the performance of MTD64 is measured and compared to that of the industry standard BIND in order to check the correctness of the design concepts of MTD64, especially of the one that we use a new thread for each request. For the performance measurements, our earlier proposed dns64perf program is enhanced as dns64perf2, which one is also documented in this paper. We found that MTD64 seriously outperformed BIND and hence our design principles may be useful for the design of a high performance production class DNS64 server. As an additional test, we have also examined the effect of dynamic CPU frequency scaling to the performance of the implementations.

    The 2010 Global Burden of Disease estimates show that 57% of all TB deaths globally occurred among adults older than 50 years of age. Few studies document the TB burden among older adults in Southern Africa. We focused on adults older than 55 years to assess the relative TB burden and associated demographic factors. A cross sectional nationally representative TB prevalence survey conducted of Zambian residents aged 15 years and above from 66 clusters across all the 10 provinces of Zambia. Evaluation included testing for TB as well as an in-depth questionnaire. We compared survey data for those aged 55 and older to those aged 15-54 years. Survey results were also compared with 2013 routinely collected programmatic notification data to generate future hypotheses regarding active and passive case finding. Among older adults with TB, 30/ 54 (55.6%) were male, 3/27 (11.1%) were HIV infected and 35/54 (64.8%) lived in rural areas. TB prevalence was higher in those aged ≥55 (0.7%) than in the 15-54 age group (0.5%). Males had higher rates of TB across both age groups with 0.7% (15-54) and 1.0% (≥55) compared with females 0.4% (15-54) and 0.6% (≥55). In rural areas, the prevalence of TB was significantly higher among older than younger adults (0.7% vs 0.3%), while the HIV infection rate was among TB patients was lower (11.1% vs 30.8%). The prevalence survey detected TB in 54/7484 (0.7%) of older adults compared to 3619/723,000 (0.5%) reported in 2013 programmatic data. High TB rates among older adults in TB endemic areas justify consideration of active TB case finding and prevention strategies.

  10. Evaluation of di-amino phenol substituted EDTA for use in radiolabelling proteins with 64Cu

    International Nuclear Information System (INIS)

    Schmidt, P.F.; Smith, S.V.; DiBartolo, N.M.

    1996-01-01

    This study involves a high yielding synthesis of a novel di-amino-phenol substituted EDTA (DAHA-EDTA) ligand and its radiolabelling chemistry with 64 Cu produced at the National Medical Cyclotron (NMC). High activity levels (up to 59.2 GBq EOB) of 64 Cu is co-produced during the production of 67 Ga from enriched 68 Zn. Waste eluent from the NMC 67 Ga production was evaporated to dryness and found to contain by products such as 57 Ni, 57 Co, 64 Cu, 67 Cu and 55 Co. A new method involving low acid concentration aqueous/organic mixtures with an anion exchange (AG 1-X8, BioRad) have been used to isolate the carrier-free 64 Cu. The specific activity of the 64 Cu (5 x 10 14 Bq/g) was found to be higher than that produce by Australian radioisotopes (ARI). The synthesis of the ligand involves the refluxing of EDTA anhydride in the presence of 4-nitro-2-amino-phenol in acetonitrile to produce the di-nitro derivative (DNHA- EDTA) in > 95% yield. The DNHA-EDTA is then reduced in the presence of activated palladium charcoal with sodium borohydride under an inert atmosphere at room temperature. The reaction mixture was acidified and the catalyst removed to obtain the final product, DAHA-EDTA. Labelling of proteins (B72.3, DD-3B6/22 and streptavidin) has been achieved with the DAHA-EDTA ligand. The reaction mixture is left to incubate for 1 h at 37 deg C and radiolabelled protein is then isolated using size exclusion chromatography

    The Hamamatsu UV-light enhanced 64-channel SiPM array of the newest generation (S13361-3050AS-08) has been examined for the purpose of being used for the Silicon Elementary Cell Add-on (SiECA) of the EUSO-SPB balloon experiment. At a room temperature of 19 . 5 °C, the average measured breakdown voltage of the array is (51 . 65 ± 0 . 11) V, the average gain is measured to (2 . 10 ± 0 . 07) ṡ 106 and the average photon detection efficiency results to (44 . 58 ± 1 . 80) % at a wavelength of (423 ± 8) nm and a bias voltage of 55 . 2V. The average dark-count rate is (0 . 69 ± 0 . 12) MHz, equivalent to a dark count rate per SiPM area of (57 ± 12) kHz /mm2, and the crosstalk probability is measured to (3 . 96 ± 0 . 64) %. These results confirm the information given by the manufacturer. Measurements performed with the newly installed Single Photon Calibration Stand at KIT (SPOCK) show the improved sensitivity to photons with wavelengths lower than 400 nm compared to the SiPM array S12642-0808PA-50, which was also investigated for comparison. Additional measurements confirm the strong temperature dependence of the SiPM characteristics as given in the data sheet. All the characterized parameters appear to be sufficiently uniform to build up a focal surface of SiPM arrays fulfilling the requirements for a telescope detecting photons in the UV range.

    Full Text Available The conventional asphalt road has almost been considered fail to serve the transportation needs. It is indicated by the occurrence of premature damage which is caused by vehicle load and climate. Starbit E-55, the polymer modified bitumen, is formulated to meet the requirement of transport development. Considering those needs, it is important to investigate the feasibility level of that modified bitumen as alternate asphalt instead of the conventional one. This research began with the measurement of the properties of hard layered AC-WC Starbit E-55, then comparing the result to 60/70 penetration of Pertamina asphalt. The next step is then, to determine the converted value so as to be close to that of Pertamina (60/70 penetration. This step is conducted by applying durability and ITS tests on the mixture. Result of the tests showed that hard layered AC-WC Starbit E-55 has better characteristic at 5.7% optimum level asphalt and 6.4% of Pertamina asphalt (60/70 penetration. Starbit E-55 converted level within hard-layered ACWC is 5.6%. The performance test result on immersion with variance of 1, 3, 5, 7 and 14 days shows that durability value of Starbit E-55 AC-WC has better performance. During the process, Starbit E-55 required 15.38% higher energy consumption.

    Full Text Available Abstract Background More people will probably continue working into old age in the future due to the increased size of aging populations in many countries. We therefore need to know more about older workers’ health in relation to their work situation and retirement. This study is a part of a theoretical development of older workers’ situations. Older workers’ situations are theoretically themed in nine areas by the authors of this study. The aims of the study were to investigate the relationship between: i diagnosed disease and factors in older workers’ situations, theoretically themed in nine areas; ii self-rated health and factors in older workers’ situations, theoretically themed in nine areas; iii diagnosed disease and self-rated health; and iv the relationships between these health measures and retirement. Methods A questionnaire-based cross-sectional study, using logistic regression, with 1,756 health care personnel aged 5564 years. The questionnaire used gave an overview of most different areas in the older workers’ situations. Result There was a difference in the participants’ frequency of objectively specified diagnosed disease and their subjectively experienced self-rated health. A bad self-rated health was related higher to early retirement than diagnosed diseases. In the multivariate model, having ‘Diagnosed disease’ was not significantly related to whether older workers thought they could not work beyond 65 years of age. A bad ‘Self-rated health’ was also more highly related to whether older workers thought they could not work beyond 65 years, than if the respondents stated that a ‘Diagnosed disease is a hindrance in my daily work’ in the multivariate model. Conclusion This study showed an important difference between older workers’ own experiences and the effect of their self-rated health and their diagnosed diseases. Subjective self-rated health seems to be more important to people’s retirement

    Newborn chicks are susceptible to Salmonella enterica serovar Enteritidis (SE). The objective of this study was to evaluate the effect of Lactobacillus probiotic isolated from chicken feces on heterophil phagocytosis in broiler chicks. A total of 150 newborn broiler chicks were divided into 5 groups (30 chicks per group) as follows: group 1 (normal control), given feed and water only, group 2 (positive control) given feed, water and SE infection, group 3 (L61 treated) given feed, water, SE infection followed by Lactobacillus salivarius L61 treatment, group 4 (L55 treated) given feed, water, SE infection followed by L. salivarius L55 treatment, and group 5 given feed, water, SE infection followed by L. salivarius L61 + L55 combination treatment. After SE infection, L. salivarius treatment lasted for 7 days. The results showed that L. salivarius L61 and L. salivarius L55 treatment, either alone or combination of both, increased the survival rate after SE infection, and upregulated heterophil phagocytosis and phagocytic index (PI). Conversely, chick groups treated with Lactobacillus showed lower SE recovery rate from cecal tonsils than that of the positive control group. The PI values of the chicken group with SE infection, followed by the combination of L. salivarius L61 and L. salivarius L55 were the highest as compared to either positive control or normal control group. Two Lactobacillus strains supplementation group showed significantly (p<0.05) higher PI value at 48 h than 24 h after treatment.

  10. [Mutation in the beta3-adrenergic receptor gene (Trp64Arg) does not influence insulin resistence, energy metabolism, fat distribution and lipid spectrum in young people. Pilot study].

    A missence mutation Trp64Arg in the beta3-adrenergic receptor gene is associated with obesity, insulin resistance, a lower metabolic rate and the earlier onset of NIDDM but the published results are controversial. We investigated the effect of this mutation on insulin resistance (euglycemic hyperinsulinemic clamp), on fat mass and fat distribution (anthropometry, bioimpedance, CT) and resting metabolic rate (indirect calorimetry), lipid spectrum and other metabolic disturbances in Czech juveniles recruited from juvenile hypertensives (H, n = 68) and controls (C, n = 81). The frequency of this mutation (determined by digestion of 210 bp PCR product with MvaI) was double in H than in C (14.7%, vs. 7.4%) and the carriers of Arg64 allele had sig. higher fasting glucose (H: p = 0.002. C: p = 0.025). Four Trp64/Arg64 and six Trp64/Trp64 men (age 23 +/- 4.2, vs. 22.5 +/- 1.9 y, BMI 26 +/- 5.5, vs. 22.9 +/- 5.1 kg/m2) took part in a detailed pilot study. But no signif. differences (Horn's method) in fasting glucose (4.6 +/- 0.6, vs. 4.9 +/- 0.4 mmol/l), in parameters of insulin resistance (M-value150-180 min. 9.1 +/- 1.1, vs. 8.9 +/- 1.5 mg glucose/kg.min(-1)), resting metabolic rate/lean body mass (RMR/kg LBM: 78.6 +/- 4.6, vs. 85.6 +/- 23.2 kJ/kg), lipid spectrum and other screened parameters were found. The lowest resting metabolic rate (RMR/kg LBM 55.4; 62.6 kJ/kg) was found in brothers (both C, Trp64/Trp64) who highly differ in body constitution (BMI 19.0 resp. 32.4 kg/m2). We suppose that in this case the energy metabolism is probably determined by other genetic loci and does not correlate with body fat mass. Our pilot study does not confirm the influence of Trp64Arg mutation in heterozygous carriers on insulin resistance, energy metabolism and lipid spectrum.

  11. LM1-64: a Newly Reported Lmc-Pn with WR Nucleus

    1993-05-01

    The object LM1-64 was reported by Lindsay & Mullan (1963, Irish Astron. J., 5, 51) as a probable PN in the LMC. Optical and UV spectra taken by us confirm that suggestion. LM1-64 is a high excitation planetary nebulae which shows evidence of having a WC central star. Broad stellar emission at lambda 4650 is detected in the optical spectrum obtained with the CTIO 4m telescope, in 1989. A UV spectrum in the range from 1200 Angstroms to 2000 Angstroms was obtained with IUE in 1990. We have measured all the emission line fluxes available and determined values for the physical conditions and chemical abundances of the nebular ionized gas. The derived values are T(OIII) = 14000K, log He/H = 11.05, log C/H = 9.48, log O/H = 8.55 and log Ne/H = 7.94. LM1-64 shows a large C enhancement in the envelope as result of the central star activity, while He, O and Ne are comparable to the average values reported for the LMC-PNe (Monk, Barlow & Clegg, 1988, MNRAS, 234, 583). We have estimated the He II Zanstra temperature of the central star to be ~ 80,000 K. This temperature is much higher than the values reported for the known LMC-PNe with WR nucleus that Monk et al. have classified as W4 to W8. The only other high temperature WR nucleus in a LMC-PN is N66 which recently showed evidence of undergoing a WR episode (Torres-Peimbert, Ruiz, Peimbert & Pe\\ na, 1993, IAU Symp. 155, eds. A. Acker & R. Weinberger, in press).

    The lifetime erythemal UV exposures received by selected population groups in south-east Queensland from birth up to an age of 55 years have been quantitatively estimated. A representative sample of teachers and other school workers received (64±22)x10 5 J m -2 to the neck compared with (4.1±1.4)x10 5 Jm -2 to the upper leg. A sample of indoor workers (bank officers, solicitors and psychologists) received approximately 2% less and a sample of outdoor workers (carpenters, tilers, electricians and labourers) received approximately 10% more to the neck than the school workers. These differences in erythemal UV exposures may influence the risk of non-melanoma skin cancer. (author)

    Multislice computed tomography (MSCT) for the noninvasive detection of coronary artery stenoses is a promising candidate for widespread clinical application because of its non-invasive nature and high sensitivity and negative predictive value as found in several previous studies using 16 to 64 simultaneous detector rows. A multi-centre study of CT coronary angiography using 16 simultaneous detector rows has shown that 16-slice CT is limited by a high number of nondiagnostic cases and a high false-positive rate. A recent meta-analysis indicated a significant interaction between the size of the study sample and the diagnostic odds ratios suggestive of small study bias, highlighting the importance of evaluating MSCT using 64 simultaneous detector rows in a multi-centre approach with a larger sample size. In this manuscript we detail the objectives and methods of the prospective ''CORE-64'' trial (''Coronary Evaluation Using Multidetector Spiral Computed Tomography Angiography using 64 Detectors''). This multi-centre trial was unique in that it assessed the diagnostic performance of 64-slice CT coronary angiography in nine centres worldwide in comparison to conventional coronary angiography. In conclusion, the multi-centre, multi-institutional and multi-continental trial CORE-64 has great potential to ultimately assess the per-patient diagnostic performance of coronary CT angiography using 64 simultaneous detector rows.

    Synthesis of pyruvaldehyde-bis-(N 4 -methylthiosemicarbazide) (PTSM), used for medical investigation and diagnosis, has been carried out in our Radiopharmaceutical Division in C.A.E. (Ezeiza Atomic Center). PTSM has been obtained introducing modifications to a previous synthesis published by H.G. Petering. (M.P. 236-238 degrees C). TLC, HPLC and IR spectrum controls have been performed. Cu-64 can be obtained by the Cu-63(n,α) and Zn-64(n,p) reactions. This last reaction has been chosen for the production in the RA-3 reactor since it leads to Cu-64 of high specific activity. Two different assays have been performed to obtain the chelate PTSM-Cu-64. The first one has been obtained by buffering the Cu-64 to pH 3-4; adding the PTSM solution to ethanol. The second assay has been carried out by buffering the Cu-64 solution with sodium acetate 3M and adding 100 μl of PTSM solution. Biodistribution studies have been carried out on NIH and rats showing a brain uptake of 4%, 30 minutes after injection. Thus, PTSM-Cu-64 proves a good brain diagnosis agent. (author). 1 ref

    Low-temperature Fourier transform infrared (FTIR) and UV difference spectroscopies combined with selective tyrosine nitration and tyrosine isotopic labeling have been used to investigate the participation of tyrosines-26 and -64 in the bacteriorhodopsin (bR) photocycle. Nitration of Tyr-26 has no detectable effect on the FTIR or UV difference spectra of the BR 570 → K 630 or BR 570 → M 412 transitions. In contrast, nitration of Tyr-64 causes changes in both the FTIR and UV spectra of these transitions. However, this nitration does not alter tyrosine peaks in the FTIR difference spectra which have previously been associated with the protonation of a tyrosinate by K 630 and the deprotonation of a tyrosine by M 412 . Instead, Tyr-64 nitration appears to affect other tyrosine peaks. These results and changes in UV difference spectra upon Tyr-64 nitration are consistent with the deprotonation of Tyr-64 by M 412 as concluded previously. Effects on chromophore vibrations caused by Tyr-64 nitration are unaltered upon reducing the nitrotyrosine to aminotyrosine with sodium dithionite. Finally, nitro-Tyr-64 causes a shift in the frequency of a positive peak at 1739 cm -1 in the BR 570 → M 412 FTIR difference spectrum which reflects the protonation of a carboxyl-containing residue. The shift does not occur for samples containing amino-Tyr-64. These data suggest that Tyr-64 may interact with this carboxyl group

  19. Wildlife underpasses on U.S. 64 in North Carolina: integrating management and science objectives

    This chapter on wildlife underpasses on U.S. Highway 64 in North Carolina is from a book on highways, wildlife, and habitat connectivity. U.S. 64 is an important route in North Carolina connecting major population centers and highways that underwent a major upgrade from a two-lane rural road to a major highway. New routes were proposed for a large portion of the project (28 miles) to improve driver safety and increase speed limits to 70 miles per hour (from the previously posted 55 mph). The authors review the geographical, historical, political, and social setting; the roadway and environmental issues; the rationale for the project; critical factors; outcomes of the project; and lessons learned. The area of the project supports high wildlife densities, including American black bears, white-tailed deer, red wolves, and bobcats. Critical factors to be incorporated into wildlife mitigation measures: driver safety, underpass construction costs, and permitting by the U.S. Fish and Wildlife Service and the U.S. Army Corps of Engineers. The U.S. 64 underpasses, completed in 2005, were the first in North Carolina designed specifically for wildlife and according to specifications provided by the North Carolina Wildlife Resources Commission (NCWRC). The authors describe the underpass specifications recommended based on this project, including size, control of public access, fencing, gates, and maintenance (notably vegetation management). The authors conclude that one of the most beneficial outcomes of this project was the fact that, since the completion of the U.S. 64 underpasses, the North Carolina Department of Transportation (NCDOT) routinely considers wildlife passageways for road projects in the state.

    The short-lived (12.7 h half-life) {sup 64}Cu radioisotope is both a {beta} {sup +} and a {beta} {sup -} emitter. This property makes {sup 64}Cu a promising candidate for novel medical applications, since it can be used simultaneously for therapeutic application of radiolabelled biomolecules and for diagnosis with PET. Following previous work on {sup 64}Cu production by deuteron irradiation of natural zinc, we report here the production of this radioisotope by deuteron irradiation of enriched {sup 64}Zn. In addition, yields of other radioisotopes such as {sup 61}Cu, {sup 67}Cu, {sup 65}Zn, {sup 69m}Zn, {sup 66}Ga and {sup 67}Ga, which were co-produced in this process, were also measured. The evaporation code ALICE-91 and the transport code SRIM 2003 were used to determine the excitation functions and the stopping power, respectively. All the nuclear reactions yielding the above-mentioned radioisotopes were taken into account in the calculations both for the natural and enriched Zn targets. The experimental and calculated yields were shown to be in reasonable agreement. The work was carried out at the Scanditronix MC-40 Cyclotron of the Institute for Health and Consumer Protection of the Joint Research Centre of the European Commission (Ispra site, Italy). The irradiations were carried out with 19.5 MeV deuterons, the maximum deuteron energy obtainable with the MC-40 cyclotron.

    Dillon, Roberto

    2015-01-01

    How did the Commodore 64 conquer the hearts of millions and become a platform people still actively develop for even today? What made it so special? This book will appeal to both those who like tinkering with old technology as a hobby and nostalgic readers who simply want to enjoy a trip down memory lane. It discusses in a concise but rigorous format the different areas of home gaming and personal computing where the C64 managed to innovate and push forward existing boundaries. Starting from Jack Tramiel's vision of designing computers "for the masses, not the classes," the book introduces the 6510, VIC-II and SID chips that made the C64 unique. It briefly discusses its Basic programming language and then proceeds to illustrate not only many of the games that are still so fondly remembered but also the first generation of game engines that made game development more approachable − among other topics that are often neglected but are necessary to provide a comprehensive overview of how far reaching the C64 in...

    In-111 ((111)In)-labeled octreotide has been clinically used for imaging somatostatin receptor-positive tumors, and radiolabeled octreotide analogs for positron emission tomography (PET) have been developed. Cu-64 ((64)Cu; half-life, 12.7 h) is an attractive radionuclide for PET imaging and is produced with high specific activity using a small biomedical cyclotron. The aim of this study is to produce and fundamentally examine a (64)Cu-labeled octreotide analog, (64)Cu-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid-D: -Phe(1)-Tyr(3)-octreotide ((64)Cu-DOTA-TOC). (64)Cu produced using a biomedical cyclotron was reacted with DOTA-TOC for 30 min at 45 degrees C. The stability of (64)Cu-DOTA-TOC was evaluated in vitro (incubated with serum) and in vivo (blood collected after administration) by HPLC analysis. Biodistribution studies were performed in normal mice by administration of mixed solution of (64)Cu-DOTA-TOC and (111)In-DOTA-TOC and somatostatin receptor-positive U87MG tumor-bearing mice by administration of (64)Cu-DOTA-TOC or (64)Cu-1,4,8,11-tetraazacyclotetradecane-1,4,8,11-tetraacetic acid-octreotide ((64)Cu-TETA-OC). The tumor was imaged using (64)Cu-DOTA-TOC, (64)Cu-TETA-OC, and FDG with an animal PET scanner. (64)Cu-DOTA-TOC can be produced in amounts sufficient for clinical study with high radiochemical yield. (64)Cu-DOTA-TOC was stable in vitro, but time-dependent transchelation to protein was observed after injection into mice. In biodistribution studies, the radioactivity of (64)Cu was higher than that of (111)In in all organs except kidney. In tumor-bearing mice, (64)Cu-DOTA-TOC showed a high accumulation in the tumor, and the tumor-to-blood ratio reached as high as 8.81 +/- 1.17 at 6 h after administration. (64)Cu-DOTA-TOC showed significantly higher accumulation in the tumor than (64)Cu-TETA-OC. (64)Cu-DOTA-TOC PET showed a very clear image of the tumor, which was comparable to that of (18)F-FDG PET and very similar to that of (64)Cu

    In-111 ( 111 In)-labeled octreotide has been clinically used for imaging somatostatin receptor-positive tumors, and radiolabeled octreotide analogs for positron emission tomography (PET) have been developed. Cu-64 ( 64 Cu; half-life, 12.7 h) is an attractive radionuclide for PET imaging and is produced with high specific activity using a small biomedical cyclotron. The aim of this study is to produce and fundamentally examine a 64 Cu-labeled octreotide analog, 64 Cu-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid-D-Phe 1 -Tyr 3 -octreotide ( 64 Cu-DOTA-TOC). 64 Cu produced using a biomedical cyclotron was reacted with DOTA-TOC for 30 min at 45 deg C. The stability of 64 Cu-DOTA-TOC was evaluated in vitro (incubated with serum) and in vivo (blood collected after administration) by high performance liquid chromatography (HPLC) analysis. Biodistribution studies were performed in normal mice by administration of mixed solution of 64 Cu-DOTA-TOC and 111 In-DOTA-TOC and somatostatin receptor-positive U87MG tumor-bearing mice by administration of 64 Cu-DOTA-TOC or 64 Cu-1,4,8,11-tetraazacyclotetradecane-1,4,8,11-tetraacetic acid-octreotide ( 64 Cu-TETA-OC). The tumor was imaged using 64 Cu-DOTA-TOC, 64 Cu-TETA-OC, and fluorodeoxyglucose (FDG) with an animal PET scanner. 64 Cu-DOTA-TOC can be produced in amounts sufficient for clinical study with high radiochemical yield. 64 Cu-DOTA-TOC was stable in vitro, but time-dependent transchelation to protein was observed after injection into mice. In biodistribution studies, the radioactivity of 64 Cu was higher than that of 111 In in all organs except kidney. In tumor-bearing mice, 64 Cu-DOTA-TOC showed a high accumulation in the tumor, and the tumor-to-blood ratio reached as high as 8.81±1.17 at 6 h after administration. 64 Cu-DOTA-TOC showed significantly higher accumulation in the tumor than 64 Cu-TETA-OC. 64 Cu-DOTA-TOC PET showed a very clear image of the tumor, which was comparable to that of 18 F-FDG PET and

    The aim of this study was to examine measurement equivalence of the newly developed Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) across age, sex, and time in a representative sample of children with newly diagnosed epilepsy. Data come from 373 children enrolled in the Health-related Quality of Life in Children with Epilepsy Study (HERQULES), a multisite prospective cohort study. Measurement equivalence was examined using a multiple-group confirmatory factor analysis framework, whereby increasingly stringent parameter constraints are imposed on the model. Comparison groups were stratified based on age (4-7 years vs. 8-12 years), sex (male vs. female), and time (measurement of health-related quality of life at diagnosis vs. 24 months later). The QOLCE-55 demonstrated measurement equivalence at the level of strict invariance for each model tested--age: χ(2) (3,123) = 4,097.3, p QOLCE-55 are perceived similarly among groups stratified by age, sex, and time and provide further evidence supporting the validity of the scale in children with epilepsy. Health professionals and researchers should be confident that group comparisons made using the QOLCE-55 are unbiased and that any group differences detected are meaningful; that is, not related to differences in the interpretation of items by informants. Future research replicating these findings is encouraged. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

    Due to the feature of high hydrolysis, tannase is widely used in food, beverage, brewing and other fields. However, high cost in producing natural tannase makes it difficult to apply tannase to industry in a large-scale. Microbial expression systems can be used for preparing numerous amount of enzyme at low cost, so in this paper Aspergillus niger N5-5 was expressed using E. coli system. Specific primers were designed based on the Aspergillus niger N5-5 sequence N3 (GenBank, No.: KP677552), and tannase gene tan was promoted to carry 6 His tag and enzyme cutting site which contains NdeI/HindIII using PCR amplification. Then, tannase gene tan was connected to expression vector by NdeI/HindIII enzyme cutting. In this way, recombinant expression vector tan -pET43.1a was formed. Then, the expression vector pET43.1a by NdeI/HindIII enzyme cutting was transformed into E. coli BL21 (DE3) to induce expression of Aspergillus niger N5-5. When the induced fungi were disrupted by the ultrasonic wave, the crude enzyme was extracted and purified by using the IMAC, and then the activity of the crude enzyme and pure enzyme was determined. According to the results of determination of the tannase activity, the tannase activity of the crude enzyme was greatly improved after the crude enzyme was purified, and the specific activity of the pure enzyme was about 8 times of that of the crude enzyme. The results of SDS-PAGE of the pure enzyme showed that the molecular mass of the pure enzyme was about 65 kDa/64-65 kDa, which was consistent with the expected result (64.2 kDa), It can be concluded that the crude enzyme solution was purified successfully. The results of pure enzyme's protein identification by Western Blotting showed that clear protein bands pro -3 were observed. Molecular mass of clear protein bands pro-3 was about 65 kDa, which was in line with the expected results (64.2 kDa). It can be seen that the aforementioned expression protein could be specifically combined

    This proposal seeks support to increase our production of the radionuclides yttrium-86 and zirconium-89 while continuing to produce copper-64. We have the advantage that we already ship out copper-64 to some 20-25 institutions per week (over 60 different institutions total including 4 Canadian sites) and thus our group already has significant experience with producing, purifying and shipping radioactive materials. A significant portion of the funds requested supported the purchase of a new hotcell for the production of zirconium-89 and yttrium-86.

    Full Text Available Our purpose is to study the effect of different component ratio of Astragalus Total Saponins (ATS and Verbena Total Glycosides (VTG on the cerebral infarction area and the serum biochemical indicators in the focal cerebral ischemia-reperfusion rat model. Compared with the model group, different component ratio of ATS and VTG could significantly improve the neurological deficit scores to the focal cerebral ischemia-reperfusion rat model, and the group of 7:3, 6:4, 5:5 got the best results; it could reduce the mortality of rat model to a certain extent, and the group of 5:5 group got the best results; it can significantly reduce the cerebral infarction area, and the group of 7:3, 5:5, 4:6 got the best results; it could significantly reduce the content of TNF-α, and the group of 8:2, 6:4 got the best results; it could significantly reduce the content of NO, and the group of 7:3, 5:5 got the best results; it could significantly increase the content of SOD, and the group of 6:4, 5:5 got the best results. This indicates that different component ratio of ATS and VTG may protect the damage of focal cerebral ischemia-reperfusion rat model to a certain extent, which are compared using the comprehensive weight method and the ratio of 5:5 was proved to be the optimal active ratio.

    BACKGROUND: The incidence of thyroid cancer (TC) is increasing although explanatory causes are lacking. A link between cancer and inflammation is well documented but unclear for autoimmune thyroid diseases and TC. We aimed to systematically review the association between Hashimoto's thyroiditis (HT......) and papillary, follicular, medullary, anaplastic thyroid carcinoma, and thyroid lymphoma (TL). METHODS: PubMed, OVID Medline, Google Scholar, and the Cochrane Library were searched from 1955 to 2016. The inclusion criteria were age >18 years, ≥20 cases of HT or TC. We collectively examined the incidence of HT...... in TC and of TC in HT. RESULTS: We identified 36 studies (64,628 subjects) published between 1955 and 2016 from 13 countries. We found a relative risk (RR) of HT among papillary thyroid cancer (PTC) of 2.36 [95% confidence intervals (CIs) 1.55-3.29, p

    1981-01-01

    Three to 20 hr after an i.p. injection of 64 Cu (half-life, 12.8 hr) into mice bearing Krebs ascites cells, a high amount of the radioisotope was recovered in the ascites cells themselves. In the control group, the radioisotope was mainly present in the liver. Similar amounts of 64 Cu were recovered in regenerating as well as in normal liver, whereas in the liver of mice bearing ascites cells, this amount was lower by 40 to 50% regardless of the ascitic volume. Thus, the copper metabolism seems to be disturbed at the hepatic level in mice bearing ascites cells. The distribution of 64 Cu was 'analyzed in DNA, RNA, and proteins from cellular lysates fractionated by CsCl gradient. There was a uniform pattern of distribution in the macromolecules from ascites cells, while 64 Cu' was preferentially associated with the protein fraction from liver. Further experiments indicated that, in vivo, 64 Cu was bound to the DNA of ascites cells

  19. The electrically silent Kv6.4 subunit confers hyperpolarized gating charge movement in Kv2.1/Kv6.4 heterotetrameric channels.

    Directory of Open Access Journals (Sweden)

    Elke Bocksteins

    Full Text Available The voltage-gated K(+ (Kv channel subunit Kv6.4 does not form functional homotetrameric channels but co-assembles with Kv2.1 to form functional Kv2.1/Kv6.4 heterotetrameric channels. Compared to Kv2.1 homotetramers, Kv6.4 exerts a ~40 mV hyperpolarizing shift in the voltage-dependence of Kv2.1/Kv6.4 channel inactivation, without a significant effect on activation gating. However, the underlying mechanism of this Kv6.4-induced modulation of Kv2.1 channel inactivation, and whether the Kv6.4 subunit participates in the voltage-dependent gating of heterotetrameric channels is not well understood. Here we report distinct gating charge movement of Kv2.1/Kv6.4 heterotetrameric channels, compared to Kv2.1 homotetramers, as revealed by gating current recordings from mammalian cells expressing these channels. The gating charge movement of Kv2.1/Kv6.4 heterotetrameric channels displayed an extra component around the physiological K(+ equilibrium potential, characterized by a second sigmoidal relationship of the voltage-dependence of gating charge movement. This distinct gating charge displacement reflects movement of the Kv6.4 voltage-sensing domain and has a voltage-dependency that matches the hyperpolarizing shift in Kv2.1/Kv6.4 channel inactivation. These results provide a mechanistic basis for the modulation of Kv2.1 channel inactivation gating kinetics by silent Kv6.4 subunits.

    Genetically modified crops that express insecticidal Bacillus thuringiensis (Bt) proteins have become a primary approach for control of lepidopteran (moth) and coleopteran (beetle) pests that feed by chewing the plants. However, the sap-sucking insects (Hemiptera) are not particularly susceptible to Bt toxins. In this study, we describe two Cry toxins (Cry64Ba and Cry64Ca) from Bt strain 1012 that showed toxicity against two important hemipteran rice pests, Laodelphax striatellus and Sogatella furcifera Both of these proteins contain an ETX/MTX2 domain and share common sequence features with the β-pore-forming toxins. Coexpression of cry64Ba and cry64Ca genes in the acrystalliferous Bt strain HD73 - resulted in high insecticidal activity against both hemipteran pests. No toxicity was observed on other pests such as Ostrinia furnacalis , Plutella xylostella , or Colaphellus bowringi Also, no hemolytic activity or toxicity against cancer cells was detected. Binding assays showed specific binding of the Cry64Ba/Cry64Ca toxin complex to brush border membrane vesicles isolated from L. striatellus Cry64Ba and Cry64Ca are Bt Cry toxins highly effective against hemipteran pests and could provide a novel strategy for the environmentally friendly biological control of rice planthoppers in transgenic plants. IMPORTANCE In Asia, rice is an important staple food, whose production is threatened by rice planthoppers. To date, no effective Bacillus thuringiensis (Bt) protein has been shown to have activity against rice planthoppers. We cloned two Bt toxin genes from Bt strain 1012 that showed toxicity against small brown planthoppers ( Laodelphax striatellus ) and white-backed planthoppers ( Sogatella furcifera ). To our knowledge, the proteins encoded by the cry64Ba and cry64Ca genes are the most efficient insecticidal Bt Cry proteins with activity against hemipteran insects reported so far. Cry64Ba and Cry64Ca showed no toxicity against some lepidopteran or coleopteran pests

    2010-01-01

    As a preliminary study for production technology of 64 Cu based on nuclear reaction of 64 Ni (p,n) 64 Cu, the nickel targets were prepared by electroplating method using acidic solution of nickel chloride - boric acid and basic solution of nickel sulphate - nickel chloride mixtures on a silver-surfaced target holder. The simulated solution of Ni(II) - Cu(II) matrix was considered as the solution of post-proton-irradiated nickel containing radioactive copper. In the presented work the irradiation of nickel target was omitted, while the radioactive copper was obtained from neutron irradiation of CuO target. The separation of radioactive copper was based on anion exchange column chromatography in which the radiocopper was conditioned to form CuCl 4 2- anion complex, while the nickel was kept as Ni 2+ cation. It was found that the electroplating deposit from the acidic solution was better than that form the basic solution. By conditioning the matrix solution in 6 M HCl, the radioactive copper was indicated in the forms of Cu 2+ and CuCl 4 2- while the nickel was in the form of Ni 2+ . In the condition of 9 M HCl, the radioactive copper was in the form of CuCl 4 2- , while the nickel was found as both Ni 2+ and CuCl 4 2- . The best condition of separation was in 8 M HCl in which the radioactive copper was in the form of CuCl 4 2- , while the nickel was in the form of Ni 2+ . The retained CuCl 4 2- was then changed back into Cu 2+ cation and eluted out from the column by using 0.05 M HCl. The γ-spectrometric analysis showed a single strong peak at 511 keV in accordance to γ-annihilation peak coming from positron decay of 64 Cu, and a very weak peak at 1346 keV related to γ-ray from internal energy transition of 64 Cu.

    1993-10-01

    A high performance 32 X 32 peak detector array is introduced. This detector consists of a 32 X 32 array of thresholding photo-transistor cells, manufactured with a standard MOSIS digital 2-micron CMOS process. A built-in thresholding function that is able to perform 1024 thresholding operations in parallel strongly distinguishes this chip from available CCD detectors. This high speed detector offers responses from one to 10 milliseconds that is much higher than the commercially available CCD detectors operating at a TV frame rate. The parallel multiple peaks thresholding detection capability makes it particularly suitable for optical correlator and optoelectronically implemented neural networks. The principle of operation, circuit design and the performance characteristics are described. Experimental demonstration of correlation peak detection is also provided. Recently, we have also designed and built an advanced version of a 64 X 64 thresholding photodetector array chip. Experimental investigation of using this chip for pattern recognition is ongoing.

  4. Differential impact of statin on new-onset diabetes in different age groups: a population-based case-control study in women from an asian country.

    Directory of Open Access Journals (Sweden)

    Chih-Wei Chen

    Full Text Available BACKGROUND: Statins reduce cardiovascular risks but increase the risk of new-onset diabetes (NOD. The aim of this study is to determine what effect, if any, statins have on the risk of NOD events in a population-based case-control study. An evaluation of the relationship between age and statin-exposure on NOD risks was further examined in a female Asian population. METHOD: In a nationwide case-controlled study, the authors assessed 1065 female NOD patients and 10650 controls with matching ages, genders and physician visit dates. The impact of statin-exposure on NOD was examined through multiple logistic regression models. Subgroup analysis for exploring the risk of NOD and statin-exposure in different age groups was performed. RESULTS: Statin-exposure was statistically significantly associated with increased new-onset diabetes risks using multivariate analysis. Interaction effect between age and statin-exposure on NOD risk was noted. For atorvastatin, the risk of cDDDs>60 was highest among the 55-64 year-olds (adjusted odds ratio [OR], 8.0; 95% confidence interval [CI], 2.57-24.90. For rosuvastatin, the risk of cDDDs>60 was highest among the 40-54 year-olds (adjusted OR, 14.8; 95% CI, 2.27-96.15. For simvastatin, the risk of cDDDs>60 was highest among the 55-64 year-olds (adjusted OR, 15.8; 95% CI, 5.77-43.26. For pravastatin, the risk of cDDDs>60 was highest among the 55-64 year-olds (adjusted OR, 14.0; 95% CI, 1.56-125.18. CONCLUSIONS: This population-based study found that statin use is associated with an increased risk of NOD in women. The risk of statin-related NOD was more evident for women aged 40-64 years compared to women aged 65 or more, and was cumulative-dose dependent. The use of statins should always be determined by weighing the clinical benefits and potential risks for NOD, and the patients should be continuously monitored for adverse effects.

  5. Identification and characterization of novel ERC-55 interacting proteins: evidence for the existence of several ERC-55 splicing variants; including the cytosolic ERC-55-C.

    ERC-55, encoded from RCN2, is localized in the ER and belongs to the CREC protein family. ERC-55 is involved in various diseases and abnormal cell behavior, however, the function is not well defined and it has controversially been reported to interact with a cytosolic protein, the vitamin D receptor. We have used a number of proteomic techniques to further our functional understanding of ERC-55. By affinity purification, we observed interaction with a large variety of proteins, including those secreted and localized outside of the secretory pathway, in the cytosol and also in various organelles. We confirm the existence of several ERC-55 splicing variants including ERC-55-C localized in the cytosol in association with the cytoskeleton. Localization was verified by immunoelectron microscopy and sub-cellular fractionation. Interaction of lactoferrin, S100P, calcyclin (S100A6), peroxiredoxin-6, kininogen and lysozyme with ERC-55 was further studied in vitro by SPR experiments. Interaction of S100P requires [Ca(2+)] of approximately 10(-7) M or greater, while calcyclin interaction requires [Ca(2+)] of >10(-5) M. Interaction with peroxiredoxin-6 is independent of Ca(2+). Co-localization of lactoferrin, S100P and calcyclin with ERC-55 in the perinuclear area was analyzed by fluorescence confocal microscopy. The functional variety of the interacting proteins indicates a broad spectrum of ERC-55 activities such as immunity, redox homeostasis, cell cycle regulation and coagulation.

    2003-06-01

    Although elderly people has a higher incidence of coronary heart disease, this group is seldom included in clinical trials. Studies performed in Spain on elderly coronary heart disease patients have been conducted in hospital settings. The aim of our study was to analyse wether the management of coronary heart disease patients over 64 years of age cared by family physicians differed from that of the rest. Cross-sectional multicentre study embedded in a clinical trial on 1,022 patients with stable coronary heart disease in which socio-demographic variables, comorbidity, treatment and cardiovascular risk- factor control were collected. Mean age was 64 10, 74.0% were men and 53.8% of subjects were over 64 years. Patients over 64 years had a greater cardiovascular comorbidity (87.7 vs 82.6%; p = 0.002) and received lower number of drugs than the rest in the prevention of recurrences (60.4 vs 70.9%; p < 0.001). Probability to receive less than two drugs on secondary prevention by subjects over 64 years was 0.45 (95% CI, 0.30-0.68) despite comorbidity, sex and cardiovascular risk profile.Conclusions. Coronary heart disease patients over 64 years receive less drugs for coronary event recurrence prevention than their younger counterparts despite their worse cardiovascular risk profile.

    Full Text Available PURPOSE: To evaluate prospectively the results obtained in 55 patients undergoing laparoscopic pyeloplasty through transperitoneal access. MATERIALS AND METHODS: From January 2005 to July 2009, fifty-five patients between 13 and 64 years old, were treated for ureteropelvic junction (UPJ stenosis via a transperitoneal laparoscopy. All patients had clinical symptoms of high urinary obstruction and hydronephrosis confirmed by imaging methods. Anderson-Hynes dismembered pyeloplasty was performed in 51 patients and Fenger technique in the other 4 cases. Patients were clinically and imaging evaluated in the postoperative period at 3 and 6 months and then followed-up annually. RESULTS: The operative time ranged from 95 to 270 min. The mean hospital stay was 2 days. The average blood loss was 170 mL. The time to return to normal activities ranged from 10 to 28 days. Anomalous vessels were identified in 27 patients, intrinsic stenosis in 23 patients and 5 patients had high implantation of the ureter. Laparoscopic pyelolithotomy was successfully performed in 6 patients with associated renal stones. That series monitoring ranged from 1 to 55 months. One patient had longer urinary fistula (11 days, 3 patients had portal infection and 6 patients had prolonged ileus. There was one conversion due to technical difficulties. From the later postoperative complications, 2 patients had re-stenosis, one determined by Anderson-Hynes technique and the other by Fenger technique. The success rate was 95.65%. CONCLUSIONS: Laparoscopic pyeloplasty has functional results comparable to conventional open technique. It offers less morbidity, with aesthetic and post-operative convalescence benefits and lower complication rates.

    2010-01-01

    Objective: To determine the optimal contrast injection protocol for 64-MDCT coronary angiography. Materials and methods: One hundred and fifty consecutive patients scheduled to undergo retrospectively electrocardiographically gated 64-MDCT. Each 30 patients were assigned to use a different contrast protocol: group 1: uniphasic protocol (contrast injection without saline flush); group 2: biphasic protocol (contrast injection with saline flush); group 3A, 3B and 3C: triphasic protocol (contrast media + different saline diluted contrast media + saline flush). Image quality scores and artifacts were compared and evaluated on both transaxial and three-dimensional coronary artery images among each contrast protocol. Results: Among the triphasic protocol groups, group 3A (30%:70% contrast media-saline mixture was used in second phase) used the least contrast media and had the least frequency of streak artifacts, but there were no significant differences in coronary artery attenuation, image quality, visualization right and left heart structures. Among the uniphasic protocol group (group 1), biphasic protocol group (group 2) and triphasic protocol subgroup (group 3A), there were no significant differences in image quality scores of coronary artery (P = 0.18); uniphasic protocol group had the highest frequency of streak artifacts (20 cases) (P < 0.05) and had the most amount contrast media (67.0 ± 5.3 ml); biphasic protocol group had the least amount of contrast media (59.9 ± 4.9 ml) (P < 0.05) and had the highest attenuation of left main coronary artery and right coronary artery (P < 0.01), but had the least amount of clear visualization right heart structure (6 cases); triphasic protocol group (group 3A) had the most amount of clear visualization right heart structures (29 cases) were the most among the three groups (P < 0.05). Conclusion: Biphasic protocol are superior to the traditional uniphasic protocols for using the least total contrast media, having the least

  19. Evaluation of [64Cu]Cu-DOTA and [64Cu]Cu-CB-TE2A Chelates for Targeted Positron Emission Tomography with an αvβ6-Specific Peptide

    Directory of Open Access Journals (Sweden)

    Sven H. Hausner

    2009-03-01

    Full Text Available Significant upregulation of the integrin αvβ6 has been described as a prognostic indicator in several cancers, making it an attractive target for tumor imaging. This study compares variants of a PEGylated αvβ6-targeting peptide, bearing either an [>18F]fluorobenzoyl prosthetic group ([18F]FBA-PEG-A20FMDV2 or different [64Cu]copper chelators (DOTA-PEG-A20FMDV2, CB-TE2A-PEG-A20FMDV2. The compounds were evaluated in vitro by enzyme-linked immunosorbent assay (against the integrin αvβ6 and the closely related integrin αvβ6 and by cell labeling (αvβ6-positive DX3puroβ6/αvβ6-negative DX3puro and in vivo using micro-positron emission tomography in a mouse model bearing paired DX3puroβ6/Dx3puro xenografts. In vitro, all three compounds showed excellent αvβ6-specific binding (50% inhibitory concentration [IC50](αvβ6 = 3 to g nmol/L; IC50(αvβ3 > 10 (μmol/L. In vivo, they displayed comparable, preferential uptake for the αvβ6-expressmg xenograft over the αvβ6-negative control (> 4:1 ratio at 4 hours postinjection. Whereas [64Cu]Cu-DOTA-PEG-A20FMDV2 resulted in increased levels of radioactivity in the liver, [64Cu]Cu-CB-TE2A-PEG-A20FMDV2 did not. Significantly, both 64Cu-labeled tracers showed unexpectedly high and persistent levels of radioactivity in the kidneys (> 40% injected dose/g at 4 and 12 hours postinjection. The findings underscore the potential influence of the prosthetic group on targeted in vivo imaging of clinically relevant markers such as αvβ6. Despite identical targeting peptide moiety and largely equal in vitro behavior, both 64Cu-labeled tracers displayed inferior pharmacokinetics, making them in their present form less suitable candidates than the 18F-labeled tracer for in vivo imaging of αvβ6

    1995-01-01

    The Monte Carlo radiation transport code MCNP has been successfully ported to two 64-bit workstations, the SGI and DEC Alpha. We found the biggest problem for installation on these machines to be Fortran and C mismatches in argument passing. Correction of these mismatches enabled, for the first time, dynamic memory allocation on 64-bit workstations. Although the 64-bit hardware is faster because 8-bytes are processed at a time rather than 4-bytes, we found no speed advantage in true 64-bit coding versus implicit double precision when porting an existing code to the 64-bit workstation architecture. We did find that PVM multiasking is very successful and represents a significant performance enhancement for scientific workstations

  1. Separation of copper-64 from copper phthalocyanine

    Battaglin, R.I.M.

    1979-01-01

    The separation of copper-64 from irradiated copper phthalocyanine by Szilard-Chalmers effect is studied. Two methods of separation are used: one of them is based on the dissolution of the irradiated dry compound in concentrated sulfuric acid following its precipitation in water. In the other one the compound is irradiated with water in paste form following treatment with water and hydrochloric acid. The influence of the crystal form of the copper phthalocyanine on the separation yield of copper-64 is shown. Preliminary tests using the ionic exchange technique for purification and changing of copper-64 sulfate to chloride form are carried out. The specific activity using the spectrophotometric technique, after the determination of the copper concentration in solution of copper-64, is calculated. (Author) [pt

    Liposomes are nanoparticles used in drug delivery that distribute over several days in humans and larger animals. Radiolabeling with long-lived positron emission tomography (PET) radionuclides, such as manganese-52 ( 52 Mn, T½=5.6days), allow the imaging of this biodistribution. We report optimized protocols for radiolabeling liposomes with 52 Mn, through both remote-loading and surface labeling. For comparison, liposomes were also remote-loaded and surface labeled with copper-64 ( 64 Cu, T½=12.7h) through conventional means. The chelator DOTA was used in all cases. The in vivo stability of radiometal chelates is widely debated but studies that mimic a realistic in vivo setting are lacking. Therefore, we employed these four radiolabeled liposome types as platforms to demonstrate a new concept for such in vivo evaluation, here of the chelates 52 Mn-DOTA and 64 Cu-DOTA. This was done by comparing "shielded" remote-loaded with "exposed" surface labeled variants in a CT26 tumor-bearing mouse model. Remote loading (90min at 55°C) and surface labeling (55°C for 2h) of 52 Mn gave excellent radiolabeling efficiencies of 97-100% and 98-100% respectively, and the liposome biodistribution was imaged by PET for up to 8days. Liposomes with surface-conjugated 52 Mn-DOTA exhibited a significantly shorter plasma half-life (T ½ =14.4h) when compared to the remote-loaded counterpart (T ½ =21.3h), whereas surface-conjugated 64 Cu-DOTA cleared only slightly faster and non-significantly, when compared to remote-loaded (17.2±2.9h versus 20.3±1.2h). From our data, we conclude the successful remote-loading of liposomes with 52 Mn, and furthermore that 52 Mn-DOTA may be unstable in vivo whereas 64 Cu-DOTA appears suitable for quantitative imaging.

    Copper-64 is an attractive radionuclide for PET imaging and is frequently used in clinical applications. The aim of this study was to perform a side-by-side comparison of the in vitro and in vivo performance of 64Cu-NODAGA-JR11 (NODAGA = 1,4,7-triazacyclononane,1-glutaric acid,4,7-acetic acid, JR11 = p-Cl-Phe-cyclo(D-Cys-Aph(Hor)-D-Aph(cbm)-Lys-Thr-Cys)D-Tyr-NH2), a somatostatin receptor 2 antagonist, with the clinically used sst2 agonist 64Cu-DOTA-TATE ((TATE = D-Phe-cyclo(Cys-Tyr-D-Trp-Lys-Thr-Cys)Thr). In vitro studies demonstrated Kd values of 5.7±0.95 nM (Bmax = 4.1±0.18 nM) for the antagonist 64/natCu-NODAGA-JR11 and 20.1±4.4. nM (Bmax = 0.48±0.18 nM) for the agonist 64/natCu-DOTA-TATE. Cell uptake studies showed the expected differences between agonists and antagonists. Whereas 64Cu-DOTA-TATE (the agonist) showed very effective internalization in the cell culture assay (with 50% internalized at 4 hours post-peptide addition under the given experimental conditions), 64Cu-NODAGA-JR11 (the antagonist) showed little internalization but strong receptor-mediated uptake at the cell membrane. Biodistribution studies of 64Cu-NODAGA-JR11 showed rapid blood clearance and tumor uptake with increasing tumor-to-relevant organ ratios within the first 4 hours and in some cases, 24 hours, respectively. The tumor washout was slow or non-existent in the first 4 hours, whereas the kidney washout was very efficient, leading to high and increasing tumor-to-kidney ratios over time. Specificity of tumor uptake was proven by co-injection of high excess of non-radiolabeled peptide, which led to >80% tumor blocking. 64Cu-DOTA-TATE showed less favorable pharmacokinetics, with the exception of lower kidney uptake. Blood clearance was distinctly slower and persistent higher blood values were found at 24 hours. Uptake in the liver and lung was relatively high and also persistent. The tumor uptake was specific and similar to that of 64Cu-NODAGA-JR11 at 1 h, but release from the tumor

    CERN Document Server

    Scheffler, Felix

    2016-01-01

    $\\mu$CernVM is a virtual appliance that contains a stripped-down Linux OS connecting to a CernVM-Filesystem (CVMFS) repository that resides on a dedicated web server. In contrast to “usual” VMs, anything that is needed from this repository is only downloaded on demand, aggressively cached and eventually released again. Currently, $\\mu$CernVM is only distributed for x86-64. Recently, ARM (market leader in mobile computing) has started to enter the server market, which is still dominated by x86-64 infrastructure. However, in terms of performance/watt, AArch64 (latest ARM 64bit architecture) is a promising alternative. Facing millions of jobs to compute every day, it is thus desirable to have an HEP virtualisation solution for AArch64. In this project, $\\mu$CernVM was successfully ported to AArch64. Native and virtualised runtime performance was evaluated using ROOT6 and CMS benchmarks. It was found that VM performance is inferior to host performance across all tests. Respective numbers greatly vary between...

    64 Cu-diacetyl-bis(N 4 -methylthiosemicarbazone) ( 64 Cu-ATSM) is a promising radiotherapy agent for the treatment of hypoxic tumors. In an attempt to elucidate the radiobiological basis of 64 Cu-ATSM radiotherapy, we have investigated the cellular response patterns in vitro cell line models. Cells were incubated with 64 Cu-ATSM, and the dose-response curves were obtained by performing a clonogenic survival assay. Radiation-induced damage in DNA was evaluated using the alkali comet assay and apoptotic cells were detected using Annexin V-FITC and propidium iodide staining methods. Washout rate and subcellular distribution of 64 Cu in cells were investigated to further assess the effectiveness of 64 Cu-ATSM therapy on a molecular basis. A direct comparison of subcellular localization of Cu-ATSM was made with the flow tracer analog Cu-pyruvladehyde-bis(N 4 -methylthiosemicarbazone). In this study, 64 Cu-ATSM was shown to reduce the clonogenic survival rate of tumor cells in a dose-dependent manner. Under hypoxic conditions, cells took up 64 Cu-ATSM and radioactive 64 Cu was highly accumulated in the cells. In the 64 Cu-ATSM-treated cells, DNA damage by the radiation emitted from 64 Cu was detected, and inhibition of cell proliferation and induction of apoptosis was observed at 24 and 36 h after the treatment. The typical features of postmitotic apoptosis induced by radiation were observed following 64 Cu-ATSM treatment. The majority of the 64 Cu taken up into the cells remained in the postmitochondrial supernatant (the cellular residue after removal of the nuclei and mitochondria), which indicates that the β - particle emitted from 64 Cu may be as effective as the Auger electrons in 64 Cu-ATSM therapy. These data allow us to postulate that 64 Cu-ATSM will be able to attack the hypoxic tumor cells directly, as well as potentially affecting the peripheral nonhypoxic regions indirectly by the β - particle decay of 64 Cu

  7. Copper-64 Dichloride as Theranostic Agent for Glioblastoma Multiforme: A Preclinical Study

    2015-01-01

    Full Text Available Glioblastoma multiforme (GBM is the most common primary malignant brain tumor in adults with a median survival time less than one year. To date, there are only a limited number of effective agents available for GBM therapy and this does not seem to add much survival advantage over the conventional approach based on surgery and radiotherapy. Therefore, the development of novel therapeutic approaches to GBM is essential and those based on radionuclide therapy could be of significant clinical impact. Experimental evidence has clearly demonstrated that cancer cells have a particularly high fractional content of copper inside the nucleus compared to normal cells. This behavior can be conveniently exploited both for diagnosis and for delivering therapeutic payloads (theranostic of the radionuclide copper-64 into the nucleus of cancerous cells by intravenous administration of its simplest chemical form as dichloride salt [64Cu]CuCl2. To evaluate the potential theranostic role of [64Cu]CuCl2 in GBM, the present work reports results from a preclinical study carried out in a xenografted GBM tumor mouse model. Biodistribution data of this new agent were collected using a small-animal PET tomograph. Subsequently, groups of tumor implanted nude mice were treated with [64Cu]CuCl2 to simulate single- and multiple-dose therapy protocols, and results were analyzed to estimate therapeutic efficacy.

    Full Text Available Octreotide analogues DOTA-TOC and DOTA-TATE were labeled with 64Cu. The influences of the ratio of peptide mass to 64Cu activity, pH value, temperature and reaction time on labeling yield were investigated. The optimum labeling was determined. In vitro stability tests in saline and 10% bovine serum had been carried out. Biodistribution of the two radiolabelled compounds in normal mice and Micro PET imaging in nude mice bearing U87MG tumor had been evaluated. The results showed that the labeling yields of 64Cu-DOTA-TOC and 64Cu-DOTA-TATE were higher than 95%. Two kinds of octreotide analogues labeled with 64Cu were quite stable in saline and decomposed slowly in 10% bovine serum at 37 ℃. Biodistribution results in normal mice showed that two 64Cu labelled tracers had similar profiles. Both of the compounds washed out from the blood quickly. High uptake of radioactivity in liver and kidneys indicated the tracers were excreted via both hepatobiliary system and renal system. At the same time, compared to 64Cu-DOTA-TOC, higher radioactivity accumulation of 64Cu-DOTA-TATE in liver and kidneys was observed. Micro PET images of U87MG tumor-bearing nude mice with 64Cu-DOTA-TOC and 64Cu-DOTA-TATE showed the tumors very clearly. The radioactivity uptake of 64Cu-DOTA-TATE in tumor was higher than that of 64Cu-DOTA-TOC. This work has paved the way for further preclinical and clinical application of 64Cu-DOTA-TOC and 64Cu-DOTA-TATE as PET tumor imaging agents.

    The aim of this study was to determine the clinical characteristics and sonographic features of lymphadenopathy (LAP) and to evaluate the treatment modalities and treatment outcomes in children with tularemia. Demographic characteristics, ultrasonographic and physical examination findings, and treatment outcomes in 55 tularemia patients (24 male and 31 female) with a mean age of 10.8 ± 4.0 years were analyzed retrospectively. Lymph node necrosis was classified in three stages based on ultrasound findings-stage 1, cortical microabscesses; stage 2, cortical and medullar abscesses; stage 3, total necrosis of the lymph node. In total, 50 (90%) of the patients had oropharyngeal, four (8%) had glandular, and one (2%) had oculoglandular tularemia. The most common symptoms were sore throat (67%) and fever (64%). LAP was the most frequently (100%) observed sign. Abscess formation was noted in 36 (65%) patients, of which seven (19%) were sonographically classified as stage 1, 20 (55%) as stage 2, and nine (26%) as stage 3. There was a statistically significant correlation between delayed treatment and stage of abscess formation in lymph nodes (p0.05). In all, nine (16%) of the patients did not respond to medical treatment, and surgical intervention was required. Tularemia should be considered in the differential diagnosis of children presenting with unexplained fever, sore throat, and cervical LAP in endemic areas. Sonographic findings may be useful in the evaluation and staging of this infection.

    The goal of this study was to characterize the relationship between tumor uptake of 64 Cu-DOTA-trastuzumab as measured by PET/CT and standard, immunohistochemistry (IHC)-based, histopathologic classification of human epidermal growth factor receptor 2 (HER2) status in women with metastatic breast cancer (MBC). Methods: Women with biopsy-confirmed MBC and not given trastuzumab for 2 mo or more underwent complete staging, including 18 F-FDG PET/CT. Patients were classified as HER2-positive (HER2+) or -negative (HER2-) based on fluorescence in situ hybridization (FISH)-supplemented immunohistochemistry of biopsied tumor tissue. Eighteen patients underwent 64 Cu-DOTA-trastuzumab injection, preceded in 16 cases by trastuzumab infusion (45 mg). PET/CT was performed 21-25 (day 1) and 47-49 (day 2) h after 64 Cu-DOTA-trastuzumab injection. Radiolabel uptake in prominent lesions was measured as SUV max Average intrapatient SUV max ( pt ) was compared between HER2+ and HER2- patients. Results: Eleven women were HER2+ (8 immunohistochemistry 3+; 3 immunohistochemistry 2+/FISH amplified), whereas 7 were HER2- (3 immunohistochemistry 2+/FISH nonamplified; 4 immunohistochemistry 1+). Median pt for day 1 and day 2 was 6.6 and 6.8 g/mL for HER 2+ and 3.7 and 4.3 g/mL for HER2- patients ( P pt overlapped between the 2 groups, and interpatient variability was greater for HER2+ than HER2- disease ( P DOTA-trastuzumab in MBC is strongly associated with patient HER2 status and is indicative of binding to HER2. The variability within and among HER2+ patients, as well as the overlap between the HER2+ and HER2- groups, suggests a role for 64 Cu-DOTA-trastuzumab PET/CT in optimizing treatments that include trastuzumab. © 2018 by the Society of Nuclear Medicine and Molecular Imaging.

  19. Study of ultraviolet light-induced DNA damage and repair: the role of the (6-4) photoproduct

    International Nuclear Information System (INIS)

    Franklin, W.A.

    1985-01-01

    Ultraviolet light induces lethal, mutagenic, and carcinogenic effects to cells. These effects are a result of the induction of photoproducts in the cellular DNA. One class of photoproducts was found as alkaline labile lesions in DNA, and it was proposed that such lesions were precursor products to the 6,4'-[pyrimidin-2'-one]-pyrimidine class of photoproducts that have been previously shown to occur in UV light-irradiated DNA. Using a series of dinucleotide compounds, the precursor compounds were isolated, and were demonstrated to be alkaline labile. These products were named the UV light-induced pyrimidine-pyrimidone (6-4) photoproducts, and their chemistry of formation in dinucleotides and DNA was studied. The formation of these photoproducts under conditions of chemical photosensitization was also measured. The most abundant of the (6-4) photoproducts is the thymine-cytosine (6-4) product, and the molecular structure of this compounds was determined by the use of infrared spectroscopy, proton NMR, and mass spectroscopy. The (6-4) products have been recently shown to be the major UV light-induced premutagenic lesions in E. coli. In E. coli, the repair of the (6-4) products is under the control of the uvrABC excision pathway. The rate of removal of (6-4) products was measured in a series of human cells lines. The rate of removal of (6-4) products from the DNA of a xeroderma pigmentosum complementation group A cell line was nearly that of the normal cells, yet these cells are unable to excise cyclobutane pyrimidine dimers. These results suggest that the removal of cyclobutane pyrimidine dimers and (6-4) products may be controlled by separate enzymatic pathways

  20. A look at the density functional theory zoo with the advanced GMTKN55 database for general main group thermochemistry, kinetics and noncovalent interactions.

    We present the GMTKN55 benchmark database for general main group thermochemistry, kinetics and noncovalent interactions. Compared to its popular predecessor GMTKN30 [Goerigk and Grimme J. Chem. Theory Comput., 2011, 7, 291], it allows assessment across a larger variety of chemical problems-with 13 new benchmark sets being presented for the first time-and it also provides reference values of significantly higher quality for most sets. GMTKN55 comprises 1505 relative energies based on 2462 single-point calculations and it is accessible to the user community via a dedicated website. Herein, we demonstrate the importance of better reference values, and we re-emphasise the need for London-dispersion corrections in density functional theory (DFT) treatments of thermochemical problems, including Minnesota methods. We assessed 217 variations of dispersion-corrected and -uncorrected density functional approximations, and carried out a detailed analysis of 83 of them to identify robust and reliable approaches. Double-hybrid functionals are the most reliable approaches for thermochemistry and noncovalent interactions, and they should be used whenever technically feasible. These are, in particular, DSD-BLYP-D3(BJ), DSD-PBEP86-D3(BJ), and B2GPPLYP-D3(BJ). The best hybrids are ωB97X-V, M052X-D3(0), and ωB97X-D3, but we also recommend PW6B95-D3(BJ) as the best conventional global hybrid. At the meta-generalised-gradient (meta-GGA) level, the SCAN-D3(BJ) method can be recommended. Other meta-GGAs are outperformed by the GGA functionals revPBE-D3(BJ), B97-D3(BJ), and OLYP-D3(BJ). We note that many popular methods, such as B3LYP, are not part of our recommendations. In fact, with our results we hope to inspire a change in the user community's perception of common DFT methods. We also encourage method developers to use GMTKN55 for cross-validation studies of new methodologies.

    The objective of our study was to compare the diagnostic accuracy of IV contrast-enhanced 64-MDCT with and without the use of oral contrast material in diagnosing appendicitis in patients with abdominal pain. We conducted a randomized trial of a convenience sample of adult patients presenting to an urban academic emergency department with acute nontraumatic abdominal pain and clinical suspicion of appendicitis, diverticulitis, or small-bowel obstruction. Patients were enrolled between 8 am and 11 pm when research assistants were present. Consenting subjects were randomized into one of two groups: Group 1 subjects underwent 64-MDCT performed with oral and IV contrast media and group 2 subjects underwent 64-MDCT performed solely with IV contrast material. Three expert radiologists independently reviewed the CT examinations, evaluating for the presence of appendicitis. Each radiologist interpreted 202 examinations, ensuring that each examination was interpreted by two radiologists. Individual reader performance and a combined interpretation performance of the two readers assigned to each case were calculated. In cases of disagreement, the third reader was asked to deliver a tiebreaker interpretation to be used to calculate the combined reader performance. Final outcome was based on operative, clinical, and follow-up data. We compared radiologic diagnoses with clinical outcomes to calculate the diagnostic accuracy of CT in both groups. Of the 303 patients enrolled, 151 patients (50%) were randomized to group 1 and the remaining 152 (50%) were randomized to group 2. The combined reader performance for the diagnosis of appendicitis in group 1 was a sensitivity of 100% (95% CI, 76.8-100%) and specificity of 97.1% (95% CI, 92.7-99.2%). The performance in group 2 was a sensitivity of 100% (73.5-100%) and specificity of 97.1% (92.9-99.2%). Patients presenting with nontraumatic abdominal pain imaged using 64-MDCT with isotropic reformations had similar characteristics for the

    2015-08-01

    Full Text Available In this work, the Liquid Impingement Erosion (LIE performances of deep-rolling (DR treated and non-treated Ti64 were investigated. Various erosion stages, from the incubation to the terminal erosion stages, could be observed. A full factorial design of experiments was used to study the effect of DR process parameters (Feed Rate, Spindle Velocity, Number of Passes, Pressure on the residual stress distribution, microhardness and surface roughness of the treated Ti64 specimens. The DR-treated Ti64 specimens exhibited improved surface microhardness, surface roughness, and large magnitude of compressive residual stresses, which were attributed to the amount of cold work induced by the DR process. Although DR improved the mechanical properties of the Ti64, the results showed that the treatment has little or no effect on the LIE performance of Ti64 but different damage modes were observed in these two cases. Evolution of the erosion stages was described based on water-hammer pressure, stress waves, radial wall jetting, and hydraulic penetration modes. The initial erosion stages were mainly influenced by water-hammer pressure and stress waves, whereas the intermediate erosion stages were influenced by the combination of the four modes together. The final erosion stages contain the four modes, however the erosion was greatly driven by the radial jetting and hydraulic penetration modes, where more material was removed. The failure mechanism of the final stages of the LIE test of both DR-treated and non-treated Ti64 was characterized as fatigue fracture. However, a brittle fracture behavior was observed in the initial and intermediate erosion stages of the DR-treated Ti64, whereas a ductile fracture behavior was observed in the non-treated Ti64. This was concluded from the micrographs of the LIE damage through different erosion stages.

    Full Text Available More than eighty percent of patients with coronary heart diseases (CHD have conventional risk factors. Prevalence of well known risk factors seems to show a different pattern in younger patients and individual above 55 years. To evaluate the pattern of conventional CHD risk factors in healthy individuals in two different age groups. A large scale population based survey of 31999 individuals from ten medical centers was designed. Screening of risk factors was performed upon these protocols: taking medical history, physical examination and blood tests of complete blood cell counts, fasting blood sugar, lipid profile, urinalysis and creatinine. Prevalence of the risk factors in healthy people aged above 55 years were: 8.1% for systolic blood pressure (SBP>140 mmHg, 3.8% for diastolic blood pressure (DBP>90mmHg, 13.9% for fasting blood glucose (FBS≥126 Mg/dl, 36.9% for total cholesterol>200 Mg/dl, 19.2% for triglyceride (TG>200 Mg/dl, 67.8% for HDL-c130 Mg/dl, 4.72 for TC/HDL-c ratio, 2.88 for LDL-c/HDL/c ratio and 4.24 for TG/HDL-c ratio. Prevalence of risk factors in individuals younger than 55 years were: 1.7% for SBP>140 mmHg, 1.2% for DBP>90 mmHg, 5.2% for FBS≥126 Mg/dl, 31.3% for TC>200 Mg/dl, 21.5% for TG>200 Mg/dl, 69.4% for HDL-c130 Mg/dl, 4.7 for TC/HDL-c ratio, 2.83 for LDL-c/HDL-c ratio and 4.43 for TG/HDL-c ratio. In univariate model of analysis: prevalence of the risk factors were significantly higher in age above 55 years than in people younger than 55 years except for hypertriglyceridemia and HDL-c200 Mg/dl P= 0.002, HDL-c140 mmHg P=0.001. Pattern of such a CHD risk factors of FBS≥126 Mg/dl, TG>200 Mg/dl, HDL-c140 mmHg demonstrated a statistically significant difference in the age above 55 years to the healthy people younger than 55 years. These results cab be implicated to set up prediction models for stratifying individuals at higher risk of CHD.

    Breast cancer radioimmunoscintigraphy targeting HER2/neu expression is a growing field of work in nuclear medicine research. Trastuzumab is a monoclonal antibody that binds with high affinity to HER2/neu, which is over expressed on breast and other tumors. Developing new tracers for the detection of this cancer is of great interest. In this study, trastuzumab was successively labeled with [ 64 Cu]CuCl 2 after conjugation with DOTA-NHS-ester. The conjugate was purified by molecular filtration, the average number of DOTA conjugated per mAb was calculated and total concentration was determined by spectrophotometric method. DOTA-trastuzumab was labeled with 64 Cu produced by 68 Zn(p,αn) 64 Cu nuclear reaction (30 MeV protons at 180 μA). Radiochemical purity, integrity of protein after radiolabeling and immunoreactivity of radiolabeled mAb trastuzumab with HER2/neu antigen and SkBr3 cell line were performed by RIA. In vitro stability of radiolabeled mAb in human serum was determined by thin layer chromatography. In vitro internalization studies were performed with the SkBr3 cell line and the tissue biodistribution of the 64 Cu-DOTA-trastuzumab was evaluated in wild-type rat (90 ± 5.5 μCi, 2, 6, 12, 24 h p.i.). The radioimmunoconjugate was prepared with a radiochemical purity of higher than 96 ± 0.5 % (ITLC) and specific activity as high as 5.3 μCi/μg. The average number of chelators per antibody for the conjugate used in this study was 5.8/1. The sample was showed to have similar patterns of migration in the gel electrophoresis. The 64 Cu-DOTA-trastuzumab showed high immunoreactivity towards HER2/neu antigen and SkBr3 cell line. In vitro stability of the labeled product was found to be more than 94 % in PBS and 82 ± 0.5 % in human serum over 48 h. In vitro internalization studies of the 64 Cu-DOTA-trastuzumab showed that up to 11.5 % of the radioimmunoconjugate internalized after 10 h.

    High doses of 55 Fe induced cytocide in maturing erythroid cells, due to the short-range deposition of decay energy. Organ damage at the time of death was evaluated in a group of 45 female mice of the C 57 BL/6 J strain given a single i.v. injection of 2,800 μCi, 1,400 μCi or 700 μCi of 55 FeCl 3 when 10 to 14 weeks old. A corresponding amount of cold iron was given to control animals by the same route. Radioiron-treated mice died spontaneously, or were killed when moribund. Mice given 2,800 μCi died after a median survival time of 27 days with severe depletion of hemopoietic cells in bone marrow and spleen, marked atrophy of lymphoid tissues and mild liver damage. After 1,400 μCi or 700 μCi, the median survival time was 117 and 439, respectively. In contrast, median survival was 847 days in control animals allowed to survive. In the two lower 55 Fe-dose groups, there was a dose-dependent pancytopenia. Atrophy of lymphoid tissues was moderate, and signs of liver damage slight. The degree of organ hemosiderosis in experimental and control animals was slight to moderate. Organ damage associated with deposition of cold iron was not apparent in tissue sections. Morphological signs of damage to non-hemopoietic organs such as the liver were not conspicuous. Direct radiation damage, primarily to the erythroid series, and competition for stem cells between the heavily depleted erythroid and the other hemopoietic cell lines must be considered among the possible factors leading to pancytopenia. Out of 14 55 Fe-treated mice who survived longer than 300 days developed tumors of hemopoietic and lymphoid tissues, or osteosarcomas. (orig./MG) [de

    Background: Management of congenital pulmonary vein stenosis is a diagnostic challenge. Echocardiography may be insufficient and thus cardiac catheterization remains the reference standard in this setting. The aim of the study was to investigate the accuracy of cardiac-non-gated CT using 64-slice technology in detecting congenital pulmonary vein stenosis in children. Materials and methods: CT examinations were consecutively performed from May 2005 to December 2006 in 13 children aged 1.5-12 months (median 5 months) for suspected congenital pulmonary vein stenosis. Cardiac-non-gated CT acquisitions were performed after the peripheral injection of contrast agent. Pulmonary veins were evaluated for their pattern of connectivity from the lung to the left atrium and for the presence of stenosis. CT findings of pulmonary vein stenosis were compared with combined findings available from echocardiography, catheterization and surgery. Results: Pulmonary veins from the right lung (n = 29) and left lung (n = 26) were evaluated as separate structures (N = 55). Of the 55 structures, 32 had surgical and/or catheterization data and 45 had echocardiography for comparison. CT visualized 100% (55/55) of the investigated structures, while echocardiography visualized 82% (45/55). In the 13 subjects CT identified 10 stenotic pulmonary veins. CT confirmed the echocardiography suspicion of pulmonary vein stenosis in 100% (7/7) and established a new diagnosis in 3 other patients. CT agreed with surgery/catheterization in 100% (10/10) of the available comparisons. Conclusion: Cardiac-non-gated CT assessed the pulmonary veins more completely than echocardiography and should be considered as a viable alternative for invasive pulmonary venography for detecting pulmonary vein stenosis in children.

    Objective In this study we aimed to assess the image quality and degree of vascular enhancement using low-concentration contrast media (LCCM) (300 mg I ml–1) and high-concentration contrast media (HCCM) (370 mg I ml–1) on 64-slice multidetector row CT (MDCT) abdominal CT angiography (CTA). In addition, we aimed to study the feasibility of using HCCM with a reduced total iodine dose. Methods CTA of the abdomen on a 64-slice MDCT was performed on 15 anaesthetised pigs. Study pigs were divided into three groups of five each based on the iodine concentration and dose received: Group A (LCCM; 300 mg I ml–1), Group B (HCCM; 370 mg I ml–1) and Group C HCCM with 20% less iodine dose. The total iodine injected was kept constant (600 mg kg–1) in Groups A and B. Qualitative and quantitative analyses were performed to study and compare each group for image quality, visibility of the branch order of the superior mesenteric artery (SMA), artefacts, degree of enhancement in the aorta and main stem arteries and uniformity of enhancement in the aorta. Groups were compared using the analysis of variance test. Results The image quality of 64-slice MDCT angiography was excellent with a mean score of 4.63 and confident visualisation of the third to fifth order branches of the SMA in all groups. Group B demonstrated superior vascular enhancement, as compared with Groups A and C (p≤0.05). Uniform aortic enhancement was achieved with the use of LCCM and HCCM with 20% less iodine dose. Conclusion 64-slice MDCT angiography of the abdomen was of excellent quality. HCCM improves contrast enhancement and overall CTA image quality and allows the iodine dose to be reduced. PMID:21081582

    {sup 64}Cu (T{sub 1/2} = 12.7 h, 37.1% {beta}{sup -}, {beta}{sup +} 17.9%) is a suitable radioisotope for use in positron emission tomography, due to its physical properties, which make it ideal for therapy ({beta}{sup -}) and for use in diagnosis ({beta}{sup +}), e.g. of hypoxic tumors. Its production is possible in biomedical cyclotrons (with protons' energy 11-18 MeV). We used for its preparation a nuclear reaction {sup 64}Ni(p,n) because it has a large cross section also at the energies of small biomedical cyclotrons. A disadvantage of this reaction is the high price of the target material, eliminated by developing a very simple way of {sup 64}Ni recycling. Ion exchange chromatography (adsorbent Bio-Rad AG1-X8) was used for separation of {sup 64}Cu from target material. Separation was carried out on the separation module developed by us. Yield of {sup 64}Cu for 100 mg {sup 64}Ni (99.09%) on the gold target was 104 MBq /{mu}Ah. To measure the product activity and for determination of radioisotope contamination there were used: a ionization chamber (Curiementor), gamma-spectrometry (HPGe detector) and liquid scintillation spectrometry (TDCR method).

    2017-01-01

    High-fructose corn syrup-55 (HFCS-55) has been suggested to be more lipogenic than sucrose, which increases the risk for nonalcoholic fatty liver disease (NAFLD) and dyslipidemia. The study objectives were to determine the effects of drinking different sugar-sweetened solutions on hepatic gene expression in relation to liver fatty acid composition and risk of NAFLD. Female rats were randomly assigned (n=7 rats/group) to drink water or water sweetened with 13% (w/v) HFCS-55, sucrose or fructose for 8 weeks. Rats drinking HFCS-55 solution had the highest (P=.03) hepatic total lipid and triglyceride content and histological evidence of fat infiltration. Rats drinking HFCS-55 solution had the highest hepatic de novo lipogenesis indicated by the up-regulation of stearoyl-CoA desaturase-1 and the highest (Ptriglyceride-rich lipoprotein from the liver was increased as shown by up-regulation of gene expression of microsomal triglyceride transfer protein in rats drinking sucrose, but not HFCS-55 solution. The observed lipogenic effects were attributed to the slightly higher fructose content of HFCS-55 solution in the absence of differences in macronutrient and total caloric intake between rats drinking HFCS-55 and sucrose solution. Results from gene expression and fatty acid composition analysis showed that, in a hypercaloric state, some types of sugars are more detrimental to the liver. Based on these preclinical study results, excess consumption of caloric sweetened beverage, particularly HFCS-sweetened beverages, should be limited. Published by Elsevier Inc.

    1975-01-01

    The decay pf low-lying levels in 55 Co has been studied by means of the 54 Fe(d,nγ) 55 Co reaction. Neutron energies were determined by time-of-flight techniques using a pulsed incident beam and a large liquid scintillator. Gamma rays in coincidence with neutrons were detected by a Ge(Li)spectrometer, Three levels at 4720.8+-0.6, 4747.1+-0.6 and 5172.4+-0.6 keV were strongly populated. The 4720 and 5172 keV levels have earlier been identified as the isobaric analogues of the 55 Fe ground state and first excited state. On the basis of a comparison of the present results with previous particle-transfer reaction studies it is suggested that the ground state analogue is split into the 4720 and 4747 keV levels. A study of excitation functions of 54 Fe(d,n)transitions at incident deuteron energies between 5.0 and 6.0 MeV show that the spectroscopic strengths obtained from (d,n) experiments in this mass region at these energies depend strongly on the incident energy.

  9. MLN64 induces mitochondrial dysfunction associated with increased mitochondrial cholesterol content

    Directory of Open Access Journals (Sweden)

    Elisa Balboa

    2017-08-01

    Full Text Available MLN64 is a late endosomal cholesterol-binding membrane protein that has been implicated in cholesterol transport from endosomal membranes to the plasma membrane and/or mitochondria, in toxin-induced resistance, and in mitochondrial dysfunction. Down-regulation of MLN64 in Niemann-Pick C1 deficient cells decreased mitochondrial cholesterol content, suggesting that MLN64 functions independently of NPC1. However, the role of MLN64 in the maintenance of endosomal cholesterol flow and intracellular cholesterol homeostasis remains unclear. We have previously described that hepatic MLN64 overexpression increases liver cholesterol content and induces liver damage. Here, we studied the function of MLN64 in normal and NPC1-deficient cells and we evaluated whether MLN64 overexpressing cells exhibit alterations in mitochondrial function. We used recombinant-adenovirus-mediated MLN64 gene transfer to overexpress MLN64 in mouse liver and hepatic cells; and RNA interference to down-regulate MLN64 in NPC1-deficient cells. In MLN64-overexpressing cells, we found increased mitochondrial cholesterol content and decreased glutathione (GSH levels and ATPase activity. Furthermore, we found decreased mitochondrial membrane potential and mitochondrial fragmentation and increased mitochondrial superoxide levels in MLN64-overexpressing cells and in NPC1-deficient cells. Consequently, MLN64 expression was increased in NPC1-deficient cells and reduction of its expression restore mitochondrial membrane potential and mitochondrial superoxide levels. Our findings suggest that MLN64 overexpression induces an increase in mitochondrial cholesterol content and consequently a decrease in mitochondrial GSH content leading to mitochondrial dysfunction. In addition, we demonstrate that MLN64 expression is increased in NPC cells and plays a key role in cholesterol transport into the mitochondria.

    1978-01-01

    Tests 54 and 55 were carried out on rings made up of the usual type of panel. Test 54 involved panels manufactured at Zolder and Test 55 involved those manufactured at Beringen. Both types of ring are 20 cm thick, 64 cm wide and have an internal diameter of 4.20 m. The tests involved application of pressure to one quarter of the circumference, the remainder of the ring being subject to restraint against the steel testing frame. Timber chocks were inserted between the ring and the frame. The reinforcements tested were those used with the normal type of panel. An account of deformation of the ring, cracking of the panels, and deformation of the concrete is given. Tables and figures summarizing the results achieved are included. Maximum load prior to breaking was 292 t in the case of the Zolder ring and 293 t in the case of the Beringen ring; initial cracking occurred at 35 and 30 t, respectively. (In French and in Dutch)

    2007-08-01

    The rat L5/6 facet joint is multisegmentally innervated from the L1 to L6 dorsal root ganglia (DRG). Tumor necrosis factor (TNF) is a known mediator of inflammation. It has been reported that satellite cells are activated, produce TNF and surround DRG neurons innervating L5/6 facet joints after facet injury. In the current study, changes in TNF receptor (p55) expression in DRG neurons innervating the L5/6 facet joint following facet joint injury were investigated in rats using a retrograde neurotransport method followed by immunohistochemistry. Twenty rats were used for this study. Two crystals of Fluorogold (FG; neurotracer) were applied into the L5/6 facet joint. Seven days after surgery, the dorsal portion of the capsule was cut in the injured group (injured group n = 10). No injury was performed in the non-injured group (n = 10). Fourteen days after the first application of FG, bilateral DRGs from T13 to L6 levels were resected and sectioned. They were subsequently processed for p55 immunohistochemistry. The number of FG labeled neurons and number of FG labeled p55-immunoreactive (IR) neurons were counted. FG labeled DRG neurons innervating the L5/6 facet joint were distributed from ipsilateral L1 to L6 levels. Of FG labeled neurons, the ratio of DRG neurons immunoreactive for p55 in the injured group (50%) was significantly higher than that in the non-injured group (13%). The ratio of p55-IR neurons of FG labeled DRG neurons was significantly higher in total L1 and L2 DRGs than that in total L3, 4, 5 and 6 DRGs in the injured group (L1 and 2 DRG, 67%; L3, 4, 5 and 6 DRG, 37%, percentages of the total number of p55-IR neurons at L1 and L2 level or L3-6 level/the total number of FG-labeled neurons at L1 and L2 level or L3-6 level). These data suggest that up-regulation of p55 in DRG neurons may be involved in the sensory transmission from facet joint injury. Regulation of p55 in DRG neurons innervating the facet joint was different between upper DRG innervated

  16. Extending R packages to support 64-bit compiled code: An illustration with spam64 and GIMMS NDVI3g data

    Science.gov (United States)

    Gerber, Florian; Mösinger, Kaspar; Furrer, Reinhard

    2017-07-01

    Software packages for spatial data often implement a hybrid approach of interpreted and compiled programming languages. The compiled parts are usually written in C, C++, or Fortran, and are efficient in terms of computational speed and memory usage. Conversely, the interpreted part serves as a convenient user-interface and calls the compiled code for computationally demanding operations. The price paid for the user friendliness of the interpreted component is-besides performance-the limited access to low level and optimized code. An example of such a restriction is the 64-bit vector support of the widely used statistical language R. On the R side, users do not need to change existing code and may not even notice the extension. On the other hand, interfacing 64-bit compiled code efficiently is challenging. Since many R packages for spatial data could benefit from 64-bit vectors, we investigate strategies to efficiently pass 64-bit vectors to compiled languages. More precisely, we show how to simply extend existing R packages using the foreign function interface to seamlessly support 64-bit vectors. This extension is shown with the sparse matrix algebra R package spam. The new capabilities are illustrated with an example of GIMMS NDVI3g data featuring a parametric modeling approach for a non-stationary covariance matrix.

  17. Test Program for the Performance Analysis of DNS64 Servers

    2015-09-01

    Full Text Available In our earlier research papers, bash shell scripts using the host Linux command were applied for testing the performance and stability of different DNS64 server imple­mentations. Because of their inefficiency, a small multi-threaded C/C++ program (named dns64perf was written which can directly send DNS AAAA record queries. After the introduction to the essential theoretical background about the structure of DNS messages and TCP/IP socket interface programming, the design decisions and implementation details of our DNS64 performance test program are disclosed. The efficiency of dns64perf is compared to that of the old method using bash shell scripts. The result is convincing: dns64perf can send at least 95 times more DNS AAAA record queries per second. The source code of dns64perf is published under the GNU GPLv3 license to support the work of other researchers in the field of testing the performance of DNS64 servers.

    Conclusion: Men aged 45–54 years undergoing RP had better overall survival compared to men aged 55–74 years, but these effects were not seen in men aged 35–44 years. There were no differences in prostate cancer specific survival in these groups.

  20. Expression of CD64 on Circulating Neutrophils Favoring Systemic Inflammatory Status in Erythema Nodosum Leprosum.

    Full Text Available Erythema Nodosum Leprosum (ENL is an immune reaction in leprosy that aggravates the patient´s clinical condition. ENL presents systemic symptoms of an acute infectious syndrome with high leukocytosis and intense malaise clinically similar to sepsis. The treatment of ENL patients requires immunosuppression and thus needs to be early and efficient to prevent both disabilities and permanent nerve damage. Some patients experience multiple episodes of ENL and prolonged use of immunosuppressive drugs may lead to serious adverse effects. Thalidomide treatment is extremely effective at ameliorating ENL symptoms. Several mechanisms have been proposed to explain the efficacy of thalidomide in ENL, including the inhibition of TNF production. Given its teratogenicity, thalidomide is prohibitive for women of childbearing age. A rational search for molecular targets during ENL episodes is essential to better understand the disease mechanisms involved, which may also lead to the discovery of new drugs and diagnostic tests. Previous studies have demonstrated that IFN-γ and GM-CSF, involved in the induction of CD64 expression, increase during ENL. The aim of the present study was to investigate CD64 expression during ENL and whether thalidomide treatment modulated its expression. Leprosy patients were allocated to one of five groups: (1 Lepromatous leprosy, (2 Borderline leprosy, (3 Reversal reaction, (4 ENL, and (5 ENL 7 days after thalidomide treatment. The present study demonstrated that CD64 mRNA and protein were expressed in ENL lesions and that thalidomide treatment reduced CD64 expression and neutrophil infiltrates-a hallmark of ENL. We also showed that ENL blood neutrophils exclusively expressed CD64 on the cell surface and that thalidomide diminished overall expression. Patient classification based on clinical symptoms found that severe ENL presented high levels of neutrophil CD64. Collectively, these data revealed that ENL neutrophils express CD64

    Smith, Joshua Wyatt; The ATLAS collaboration

    2016-01-01

    The ATLAS experiment explores new hardware and software platforms that, in the future, may be more suited to its data intensive workloads. One such alternative hardware platform is the ARM architecture, which is designed to be extremely power efficient and is found in most smartphones and tablets. CERN openlab recently installed a small cluster of ARM 64-bit evaluation prototype servers. Each server is based on a single-socket ARM 64-bit system on a chip, with 32 Cortex-A57 cores. In total, each server has 128 GB RAM connected with four fast memory channels. This paper reports on the port of the ATLAS software stack onto these new prototype ARM64 servers. This included building the "external" packages that the ATLAS software relies on. Patches were needed to introduce this new architecture into the build as well as patches that correct for platform specific code that caused failures on non-x86 architectures. These patches were applied such that porting to further platforms will need no or only very little adj...

    The NA64 experiment, known as P348 before official approval, was proposed to the CERN SPSC on January 2014 with main goal the search for the following decay modes A′ → invisible A′ → e−e+ (1) In March 2016 P348 was granted approval by the CERN Research Board and received the title NA64. Since having been promoted, the experiment has been conducting the searches the searches for the processes mentioned above at the CERN SPS. NA64 is a fixed target experiment which utilizes the active beam dump. The detection of rare processes is based on the missing energy techniques. Such techniques are used for particles whose interaction with the detector is very small, so that they escape the detection and carry away some energy. A significant missing energy in the experiment means that such particles are produced. The method of the search for the A′ → invisible decay is as follows. If the A′ exists it could be produced via the kinetic mixing with bremsstrahlung photons in the reaction of high-energy elec...

    The hypoxia PET tracer (64)Cu-diacetyl-bis(N(4)-methylthiosemicarbazonate) ((64)Cu-ATSM) has shown promising results in clinical studies. However, concerns have been raised with regard to the possible effect of copper metabolism and free copper on tumor uptake and thereby the robustness of (64)Cu-ATSM as a hypoxia marker. In this study, accumulation and distribution of (64)Cu-ATSM and (64)CuCl2 in tumor tissue were compared with partial pressure of oxygen (pO2) probe measurements. One-hour dynamic PET scans were performed on nude mice bearing subcutaneous human head and neck tumors (FaDu) and human colorectal tumors (HT29) after administration of either (64)Cu-ATSM or (64)CuCl2. Subsequently, tracks were generated and track markers were positioned in tumors to allow for registration of their exact location on the high-resolution CT scan. After completion of the CT scan, pO2 probe measurements were performed along each track. PET and CT images were coregistered and ROIs drawn on the basis of the location of track markers and pO2 probe measurement depth. A linear mixed model for repeated measures was applied for the comparison of PET tracer uptake to corresponding pO2 values. Comparable uptake of (64)Cu-ATSM and (64)CuCl2 was found in the kidney, muscle, and liver of all animals, but (64)CuCl2 showed a higher uptake 10-60 min after injection in both tumor models. Significant differences were also found for both tumor-to-muscle and tumor-to-liver ratios. The intratumoral distribution of (64)Cu-ATSM, but not (64)CuCl2, showed a significant negative relationship with pO2 measurements in FaDu tumors. However, this relationship was not found in HT29 tumors. (64)Cu-ATSM and (64)CuCl2 displayed different uptake in tumors. In human head and neck xenografts, (64)Cu-ATSM but not (64)CuCl2 reflected pO2 measurements, indicating that (64)Cu-ATSM is a hypoxia-specific marker in this tumor type. However, data from colorectal cancer xenografts indicated that (64)Cu-ATSM may not be

    The radiation exposure of four different 64-slice MDCT-colonography (CTC) protocols was evaluated using an Alderson-Rando phantom. Protocols using 30 mAs (collimation 20 x 1.2mm), 50 mAs (collimation 20 x 1.2 and 64 x 0.6mm) and 80 mAs (20 x 1.2 mm) representing screening low-dose, routine, narrow collimation and oncologic staging setups were measured with an Alderson-Rando phantom (Alderson Research Laboratories Inc.). Scans were performed on a 64-row MDCT (SOMATOM Sensation 64, Siemens) simulating the prone and supine positions with a constant voltage of 120 kV. Dose values (male/female) were 2.5/2.9, 3.8/4.2, 4.2/4.5 and 5.7/6.4 mSv for 30, 50 (20 x 1.2 and 64 x 0.6 mm) and 80 mAs, respectively. Measurements showed an elevated dose for females (11.5% mean; compared to males). Use of narrow collimation combined with 50 mAs resulted in a small increase of dose exposure of 10.5 (male) and 7.1% (female). Gonad doses ranged from 0.9 to 2.6 mSv (male) and from 1.5 to 3.5 mSv (female). In all protocols, the stomach wall, lower colon, urinary bladder and liver were slightly more highly exposed (all <2.3 mSv) than the other organs, and the breast dose was <0.3 mSv in every setup. Values of radiation exposure in 64- and 16-slice CTC differ only marginally when using the narrow collimation. In 64-slice CTC, the use of narrow (64 x 0.6 mm) collimation shows slightly elevated dose values compared to wider (20 x 1.2 mm) collimation. (orig.)

    Management of CML has changed markedly since the introduction of tyrosine kinase inhibitors (TKIs). However stem cell transplantation (SCT) remains a valid therapeutic modality especially in developing countries due to its relatively lower cost. We aim to compare between imatinib mesylate and SCT as regard outcome in CML in the pediatric age group. Forty-eight patients with newly diagnosed CML in the chronic phase, aged 3 to 18 years were enrolled in this prospective study. Patients without a matched donor (Group I; N=30) were assigned to receive imatinib mesylate at a dose of 340mg÷m2÷day, while patients with a fully matched related donor (Group II; N=18), were offered SCT. Response (hematologic, cytogenetic and molecular), side effects and survival were analyzed. Complete hematologic response was obtained in 97% of the patients in group I and 94% in group II. Major cytogenetic response (CyR) was obtained in 80% of patients in group I and 100% in group II. Complete CyR was 57% in group I and 64% in group II. Major molecular response (MMR) was 36% in group I and 50% in group II with no significant difference between both groups. Six years overall survival (OS) was 87% in the 1st group and 61% in the 2nd group (pSCT group (55% had GVHD and 78% had infection). Imatinib mesylate has a superior OS and EFS than SCT in children. It is generally safe and well tolerated. Imatinib mesylate should be the 1st line treatment of pediatric patients with CML in the chronic phase. CML- Imatinib- SCT- Pediatrics.

    "HIDROROUTE 55" Saving water is a recurrent topic for students in Spain because the Mediterranean zone suffers periodically severe droughts. Any student knows it and is able to repeat some basic advices like "take showers instead of baths, or "close the tap when brushing your teeth..." But maybe this is a quite superficial awareness about shortage and saving water. Where does the home flowing water come from? How can we be sure that this water is clean and safe to drink? And, tomorrow or next week, will be there water in our tap? Perhaps working in these questions is a good way to understand how difficult is to get water to our homes. In order to deepen in the question we are preparing a teaching unit titled "Hydro route 55: from the Earth to la Maurina trough the water" on 1rst ESO level students (12 years old) of the secondary public school "Institut les Aymerigues" in Terrassa (Barcelona). Students' tasks will be to search information about the way water gets to their homes, including water cycle, treatment and saving water... This unit belongs to an integrated project with all areas involved (history, mathematics, technology, languages and music) that aims to approach students to different aspects of their zone in Terrassa (La Maurina) and it will be implemented at the end of the second term, just some weeks before the Vienna's meeting. School and teaching team: Institut les Aymerigues is a new school that this year has only 1rst ESO students (12 years old). Teaching staff is engaged in developing an integrated and based on competences curriculum. In this context we integrate English and Science content in a unified teaching schedule of six hours per week for the students. One English teacher and two Science teachers are involved in it. In addition we have three student teachers from "Master of Secondary Teachers Training" that are in charge of preparing the Hydroroute 55 activities with the titular teachers. We illustrate students' tasks such as the

    The aim of our study was to evaluate the value of coronal image reconstructions of HRCT with using 64 MDCT scans for the assessment of bronchiectasis. Chest CT scans (0.6-mm collimation, table speed of 14 mm/sec and a rotation time of 0.5 sec) that employed 64 MDCT images (Somatom Sensation 64, Siemens) without contrast media were performed in 56 patients (21 males and 35 females, mean age: 55 years) who displayed hemoptysis. The images were reconstructed with a 1 mm slice thickness in the axial (10 mm apart) and coronal (10 mm apart) planes with using a high frequency algorithm, and they were sent to PACS monitors. The axial images were assessed with and without the coronal images by two radiologists at two separate occasions. The presence of bronchiectasis was decided upon by consensus diagnosis of the two radiologists. The detection rates of bronchiectasis were compared between the readings with using the axial images alone and the readings with using both the axial and coronal images. The detection rate of bronchiectasis was significantly higher with using both the axial and coronal images than with using with axial images alone (82.1%, 46/56 patients Vs 64.3%, 36/56 patients, respectively, ρ = 0.001). The detection rates for all the lobes, except for the superior division of the left upper lobe, were significantly improved with using both the axial and coronal images (RUL; ρ = 0.013, RML; ρ = 0.002, RLL; 0.024, Lt lingular segment; ρ = 0.004, LLL; ρ = 0.018). The coronal images of HRCT with using 64 MDCT improved the detection rate of bronchiectasis in the patients with hemoptysis when they were used in conjunction with the standard axial images. We suggest that HRCT with the coronal images should be obtained for the patients with hemoptysis, despite that the simple chest radiographs are often normal or they have non-specific findings

    To determine and compare the prognostic criteria (tumor, size, lymph node involvement, clinical staging and histological type and grade) for breast neoplasms detected at screening mammography in women 40 to 49 and 50 to 64 years of age. We review a total of 216 unelected cases of breast carcinoma diagnosed in our hospital, 109 discovered at screening mammography (45 in women aged 40 to 40 years and 64 in women aged 50 to 64 years). We found no statistically significant differences between the two age groups with respect to tumor size, lymph node involvement or clinical staging. In all, 64.4% and 61.6% of the carcinomas detected in 40 to 49-year-old women and in 50 to 64-year-old women, respectively, corresponded to clinical stages 0 and 1. Nor did we observe significant differences with respect to the histological type or grade. Given the similarity in the major prognostic criteria for the neoplasms diagnosed in both age groups, we consider that the performance of screening mammography in women aged 40 to 49 years allows the detection of breast carcinomas at stages as early as those in which these lesions are detected in women aged 50 to 64 years.

    Improved bifunctional chelates (BFCs) are needed to facilitate efficient {sup 64}Cu radiolabeling of monoclonal antibodies (mAbs) under mild conditions and to yield stable, target-specific agents. The utility of two novel BFCs, 1-Oxa-4,7,10-triazacyclododecane-5-S-(4-isothiocyanatobenzyl)-4,7,10-triacetic acid (p-SCN-Bn-Oxo-DO3A) and 3,6,9,15-tetraazabicyclo[9.3.1]pentadeca-1(15),11,13-triene-4-S-(4-isothiocyanatobenzyl)-3,6,9-triacetic acid (p-SCN-Bn-PCTA), for mAb imaging with {sup 64}Cu were compared to the commonly used S-2-(4-isothiocyanatobenzyl)-1,4,7,10-tetraazacyclododecane-tetraacetic acid (p-SCN-Bn-DOTA). The BFCs were conjugated to trastuzumab, which targets the HER2/neu receptor. {sup 64}Cu radiolabeling of the conjugates was optimized. Receptor binding was analyzed using flow cytometry and radioassays. Finally, PET imaging and biodistribution studies were done in mice bearing either HER2/neu-positive or HER2/neu-negative tumors. {sup 64}Cu-Oxo-DO3A- and PCTA-trastuzumab were prepared at room temperature in >95% radiochemical yield (RCY) in <30 min, compared to only 88% RCY after 2 h for the preparation of {sup 64}Cu-DOTA-trastuzumab under the same conditions. Cell studies confirmed that the immunoreactivity of the mAb was retained for each of the bioconjugates. In vivo studies showed that {sup 64}Cu-Oxo-DO3A- and PCTA-trastuzumab had higher uptake than the {sup 64}Cu-DOTA-trastuzumab at 24 h in HER2/neu-positive tumors, resulting in higher tumor to background ratios and better tumor images. By 40 h all three of the {sup 64}Cu-BFC-trastuzumab conjugates allowed for clear visualization of the HER2/neu-positive tumors but not the negative control tumor. The antibody conjugates of PCTA and Oxo-DO3A were shown to have superior {sup 64}Cu radiolabeling efficiency and stability compared to the analogous DOTA conjugate. In addition, {sup 64}Cu-PCTA and Oxo-DO3A antibody conjugates may facilitate earlier imaging with greater target to background ratios than

    Full Text Available Smoking is known as a major cause of chronic obstructive pulmonary disease (COPD and hence immediate and effective interventions are required for its elimination. This study aimed to collect valid data with regard to cigarette smoking in adult population of north of Iran for policy making by a meta-analysis of the documents of national non-communicable disease risk factors surveillance system. We investigated relevant evidences by searching in published and non-electronic databases. Data were extracted based on variables such as year of the study, sex, age group and prevalence of smoking habit. Based on results of heterogeneity, we applied fixed or random effects model to estimate the overall prevalence of cigarette smoking. All analyses were performed using STATA 11 software. A total of 20747 subjects (10381 males and 10366 females in five age groups 15-24, 25-34, 35-44, 45-54 and 55-64 years were interviewed. Meta-analysis in men and women showed prevalence of 19.2% (15.8-22.6% and 0.3% (0.2-0.5% respectively. Results of the present meta-analysis showed as much as one fifth of male population of north of Iran are smoker. Subgroup analysis also revealed that the rate of smoking was higher among the middle-aged men.

    The incidence of acute myocardial infarction (AMI) in men exceeds that in women. The extent of this sex disparity varies widely between countries. Variations may also exist between ethnic minority groups and the majority population, but scientific evidence is lacking. A nationwide register-based cohort study was conducted (n = 7,601,785) between 1997 and 2007. Cox Proportional Hazard Models were used to estimate sex disparities in AMI incidence within the Dutch majority population and within ethnic minority groups, stratified by age (30-54, 55-64, ≥65 years). AMI incidence was higher in men than in women in all groups under study. Compared with the majority population (hazard ratio (HR): 2.23; 95% confidence interval (95% CI): 2.21-2.25), sex disparities were similar among minorities originating from the immediate surrounding countries (Belgium, Germany), whereas they were greater in most other minority groups. Most pronounced results were found among minorities from Morocco (HR: 3.48; 95% CI: 2.48-4.88), South Asia (HR: 3.92; 95% CI: 2.45-6.26) and Turkey (HR: 3.98; 95% CI: 3.51-4.51). Sex disparity differences were predominantly evident in those below 55 years of age, and were mainly provoked by a higher AMI incidence in ethnic minority men compared with men belonging to the Dutch majority population. Sex disparities in AMI incidence clearly varied between ethnic minorities and the Dutch majority population. Health prevention strategies may first target at a reduction of AMI incidence in young ethnic minority men, especially those originating from Turkey and South Asia. Furthermore, an increase in AMI incidence in their female counterparts should be prevented. © The European Society of Cardiology 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Objective: To investigate the impact of imaging quality of pitch on coronary CT angiography (CTA) with 64-detector row CT. Methods: 566 patients were divided into four groups according to heart rate (≤ 50, 51 ∼ 70, 71 ∼ 80 and ≥ 80 bpm). Three dimensional reconstructions were used such as volume rendering (VR), maximum intensity projection(MIP) and curved planar reformation (CPR). Each group was divided into control group and experimential group randomly, using normal pitch and revised pitch respectively, and the imaging quality and influencing factors were analyzed among the four groups. Results: There was significant difference in imaging quality among the four groups (P < 0.05). Each group had difference in imaging quality with normal pitch and revised pitch. Conclusions: The revised pitch helps to improve the imaging quality and meet the demand of diagnosis. (authors)

    2014-01-01

    Full Text Available Objectives: This study compares cancerogenesis risks posed by the 64 row detector and the 320 row detector computed tomography scanners used during coronary computed tomography angiography (CCTA following decennial screening guidelines. Material and Methods: Data of the radiation absorbed after CCTA by lung, thyroid, and female breast in patients between 50 and 70 years of age obtained from prior published literature for the 64 row CT scanner were compared with data from our study using 320 row detector CT scanner. Data from the 64 row and the 320 row detector CT scanners was used to determine lifetime attributable risks (LAR of cancer based on the biological effects of ionizing radiation (BEIR VII report. Results: The relative reduction of LAR (% for 50-, 60-, and 70-year-old patients undergoing scanning with the 320 row detector CT scanner was 30% lower for lung, and more than 50% lower for female breast when compared with results from 64 row detector CT scanner. The use of 320 row detector CT would result in a combined cumulative cancer incidence of less than 1/500 for breast in women and less than 1/1000 for lung in men; By comparison, this is much lower than other more common risk factors: 16-fold for lung cancer in persistent smokers, 2-fold for breast cancer with a first degree family member history of breast cancer, and 10-fold for thyroid cancer with a family member with thyroid cancer. Decennial screening would benefit at least 355,000 patients from sudden cardiac death each year, 94% of whom have significant coronary artery disease, with at least one stenosis >75%. LAR for thyroid cancer was negligible for both scanners. Conclusion: Lung and female breast LAR reductions with 320 row detector compared with 64 row detector CT are substantial, and the benefits would outweigh increased cancer risks with decennial screening in the age group of 50-70 years.

    Objective: To investigate the expression of CD(55) and myeloperoxidase (MPO) on neutrophils in patients with MPO-specific anti-neutrophil cytoplasmic antibody associated vasculitis(MPO-AAV), and analyze the relationship between the expression and clinical manifestation. Methods: Forty untreated patients with active MPO-AAV (patient group) and 30 healthy volunteers (control group) were enrolled in this study. The CD(55) on neutrophils and both membrane and cytoplasmic MPO were detected by flow cytometry. Serum fragment-from the activated complement factor B(Ba) and MPO were measured by ELISA. The clinical activity of vasculitis was valued by Birmingham vasculitis activity score-version 3(BVAS-V3). The significance of laboratory data was evaluated by Spearman correlation test and multivariate linear regression analysis. Results: (1)The mean fluorescence intensity(MFI) of CD(55) expressed on neutrophils was significantly higher than that in control group[4 068.6±2 306.0 vs 2 999.5±1 504.9, P =0.033]. Similar results of serum MPO and Ba in patient group were found compared to controls [500.0(381.0, 612.7) IU/L vs 286.9(225.5, 329.1) IU/L, P <0.001; 35.2(25.2, 79.5) ng/L vs 18.0(15.0, 28.0) ng/L, P <0.001], respectively. However, MIF of cytoplasmic MPO in patients was significantly lower than that of control group(1 577.1±1 175.9 vs 3 105.3±2 323.0, P =0.003) . (2) In patient group, cytoplasmic intensity of MPO was negatively associated with the serum levels of MPO( r =-0.710, P <0.001) and Ba ( r =-0.589, P =0.001). Moreover, serum MPO was positively associated with serum Ba( r =0.691, P <0.001). Membrane intensity of CD(55) on neutrophils was positively correlated with patient age ( r =0.514, P =0.001), C reactive protein ( r =0.376, P =0.018), peripheral neutrophils count ( r =0.485, P =0.001) and BVAS-V3 ( r =0.484, P =0.002), whereas negative correlation between membrane CD(55) and disease duration was seen ( r =-0.403, P =0.01).

    The life expectancy growth is a general trend for the world population, which translates into an increase of people older than 55 years in Western societies. This entails to the rise of health problems as well as large investments in healthcare. In general, we are spectators Y tambe voldria saber si ens pots fer una asse of how a large group of citizens have a new life after retirement. The XXI century societies are facing the problem of the need of a healthy population, even after retirement. There is a need in developing new strategies to allow those citizens to improve their knowledge of the environmental changes. The research in Soil Science and related disciplines is the strategy we are using on the Geograns program to inform the students (older than 55) about the changes the Earth and the Soil System are suffering. And this should be done in a healthy and active teaching environment. The NAUGRAN program is being developed by the University of Valencia for more than 10 years and shows the advances on education for senior students. Within this program, Geograns is bringing the environmentalist ideas to the students. This is a difficult task as those students were born in a society were nature was created to be exploited and not to be conserved (e.g. Green Revolution, agricultural transformations of the 60's in Spain). This is the reason why the University of Valencia developed at the end of the 90's a program to teach students older than 55. This paper shows the advances on new strategies developed during 2013 with a group of these senior students. The main strategy was to take the students to visit the nature and to explain the functioning of the Earth and Soil System. Those visits were organized with the collaboration of scientist, environmentalist, farmers and technicians; and the guiding thread was trekking. This mix showed our students different views and sides of the same phenomena (e.g. tillage operations, soil erosion problems, water quantity and

    To analyze the association between the Trp64Arg polymorphism of the ADRB3 gene, maximal fat oxidation rates and the lipid profile levels in non-obese adolescents. 72 schoolchildren, of both genders, aged between 11 and 17 years, participated in the study. The anthropometric and body composition variables, in addition to total cholesterol, HDL-c, LDL-c, triglycerides, insulin, and basal glycemia, were evaluated. The sample was divided into two groups according to the presence or absence of the polymorphism: non-carriers of the Arg64 allele, i.e., homozygous (Trp64Trp: n=54), and carriers of the Arg64 allele (Trp64Arg+Arg64Arg: n=18), in which the frequency of the Arg64 allele was 15.2%. The maximal oxygen uptake and peak of oxygen uptake during exercise were obtained through the symptom-limited, submaximal treadmill test. Maximal fat oxidation was determined according to the ventilatory ratio proposed in Lusk's table. Adolescents carrying the less frequent allele (Trp64Arg and Arg64Arg) had higher LDL-c levels (p=0.031) and lower maximal fat oxidation rates (p=0.038) when compared with non-carriers (Trp64Trp). Although the physiological processes related to lipolysis and lipid metabolism are complex, the presence of the Arg 64 allele was associated with lower rates of FATMAX during aerobic exercise, as well as with higher levels of LDL-c in adolescents.

    A population-based controlled study to determine whether adult (55-74 years) neurological disease deaths are continuing to rise and are there significant differences between America and the twenty developed countries 1989-91 and 2012-14. Total Neurological Deaths (TND) rates contrasted against control Cancer and Circulatory Disease Deaths (CDD) extrapolated from WHO data. Confidence intervals compare USA and the other countries over the period. The Over-75's TND and population increases are examined as a context for the 55-74 outcomes. Male neurological deaths rose >10% in eleven countries, the other countries average rose 20% the USA 43% over the period. Female neurological deaths rose >10% in ten counties, averaging 14%, the USA up 68%. USA male and female neurological deaths increased significantly more than twelve and seventeen countries, respectively. USA over-75s population increased by 49%, other countries 56%. Other countries TND up 187% the USA rose fourfold. Male and female cancer and CDD fell in every country averaging 26% and 21%, respectively, and 64% and 67% for CDD. Male neurological rates rose significantly more than Cancer and CCD in every country; Female neurological deaths rose significantly more than cancer in 17 countries and every country for CDD. There was no significant correlation between increases in neurological deaths and decreases in control mortalities. There are substantial increases in neurological deaths in most countries, significantly so in America. Rises in the 55-74 and over-75's rates are not primarily due to demographic changes and are a matter of concern warranting further investigation. © 2017 John Wiley & Sons A/S.

    Full Text Available Este artículo presenta una reconceptualización del concepto de envejecimento. Se plantea la necesidad de revisar las etapas del desarrollo psicológico descritas por Erikson. Los recientes cambios demográficos y la prolongación de la expectativa de vida justifican el replanteamiento conceptual. Actualmente la tercera edad no es la última edad. Características que se le atribuían a este período de la vida ahora corresponden a la cuarta edad. El Departamento de Servicios Humanos de Hartford ha creado el Club 55, un proyecto basado en este nuevo paradigma.

    The study analyses whether and to what degree specific routes into retirement affect older people, i.e. the relationship between heterogeneous exit patterns and post-retirement health and wellbeing. We used longitudinal data from two points in time; data related to t 0 were collected in 1993, 1994, 1995 and 1996 and data related to t 1 were collected in 2002 and 2003 ( N  = 589). We focused on older people (55+ at t 1 ) who were employed at t 0 and retired at t 1 . We used confirmative factor analysis to identify identical measures of health and wellbeing at both t 0 and t 1 . Hence, we were able to control for pre-retirement health and wellbeing when evaluating the effects of different exit routes. These routes were defined as dependence on incomes from sickness benefit, disability pension, part-time pension, unemployment insurance and active labour market programmes. Our initial structural equation model showed a clear relation between exit routes and post-retirement wellbeing. People who prior to retirement were pushed into social benefit programmes related to health and unemployment were significantly worse off as retirees, especially those with health-related benefits. However, these relationships disappeared once pre-retirement wellbeing was added to the model. Our main conclusion is that post-retirement wellbeing first and foremost is a consequence of accumulation of advantages and disadvantages during the life course. Both labour market exit routes and post-retirement wellbeing can be seen as outcomes of this process. There are no independent effects of the retirement process. Judging from our findings, there is no reason to believe that involvement in social security programmes allowing early retirement on health grounds has any additional negative consequences for health and wellbeing.

    Objectives: To investigate the diagnostic accuracy of 64-slice multidetector computed tomography (64-CT) for detection of in-stent restenosis (ISR) in an unselected, consecutive patient population. Background: Detection of in-stent restenosis by cardiac CT would be a major advance for the evaluation of patients suspected of having ISR. However, the diagnostic accuracy of current generation 64-CT in this context is not fully established. Methods: We conducted a prospective study on patients with stable angina or acute coronary syndrome with no prior history of coronary artery disease. Six months after percutaneous coronary intervention (PCI) with stent placement they underwent a 64-CT scan (Toshiba Multi-Slice Aquilion 64) and consequently a repeat coronary angiography for comparison. Cardiac CT data sets were analyzed for the presence of in-stent restenosis by two independent expert readers blinded to the coronary angiographic data. Results: Ninety-three patients with a total of 140 stents were evaluated. Males comprised 82% of the study group and the mean age was 63 {+-} 10 years. The mean time from PCI to the repeat coronary angiography was 208 {+-} 37 days and the mean time from 64-CT to repeat coronary angiography was 3.7 {+-} 4.9 days. The restenosis rate according to coronary angiography was 26%. Stent diameter, strut thickness, heart rate and body mass index (BMI) significantly affected image quality. The sensitivity, specificity, positive and negative predictive values of 64-CT for detection of in-stent restenosis were 27%, 95%, 67% and 78%, respectively. Conclusions: Current generation, 64-slice CT, remains limited in its ability to accurately detect in-stent restenosis.

    Full Text Available Snakebite envenomation is a neglected condition that constitutes a public health problem in tropical and subtropical countries, including Brazil. Interestingly, some animals are resistant to snake envenomation due to the presence of inhibitory glycoproteins in their serum that target toxic venom components. DM64 is an acidic glycoprotein isolated from Didelphis aurita (opossum serum that has been characterized as an inhibitor of the myotoxicity induced by bothropic toxins bearing phospholipase A2 (PLA2 structures. This antitoxic protein can serve as an excellent starting template for the design of novel therapeutics against snakebite envenomation, particularly venom-induced local tissue damage. Therefore, the aim of this work was to produce a recombinant DM64 (rDM64 in the methylotrophic yeast Pichia pastoris and to compare its biological properties with those of native DM64. Yeast fermentation in the presence of Pefabloc, a serine protease inhibitor, stimulated cell growth (~1.5-fold, increased the rDM64 production yield approximately 10-fold and significantly reduced the susceptibility of rDM64 to proteolytic degradation. P. pastoris fermentation products were identified by mass spectrometry and Western blotting. The heterologous protein was efficiently purified from the culture medium by affinity chromatography (with immobilized PLA2 myotoxin and/or an ion exchange column. Although both native and recombinant DM64 exhibit different glycosylation patterns, they show very similar electrophoretic mobilities after PNGase F treatment. rDM64 formed a noncovalent complex with myotoxin II (Lys49-PLA2 from Bothrops asper and displayed biological activity that was similar to that of native DM64, inhibiting the cytotoxicity of myotoxin II by 92% at a 1:1 molar ratio.

    Recently, nanoparticles have received a great deal of interest in diagnosis and therapy applications. Since nanoparticles possess intrinsic features that are often required for a drug delivery system and diagnosis, they have potential to be used as platforms for integrating imaging and therapeutic functions, simultaneously. Intrinsic issues that are associated with theranostic nanoparticles, particularly in cancer treatment, include an efficient and straightforward radiolabeling method for understanding the in vivo biodistribution of nanoparticles to reach the tumor region, and monitoring therapeutic responses. Herein, we investigated a facile and highly efficient strategy to prepare radiolabeled nanoparticles with {sup 64}Cu via a strain-promoted azide, i.e., an alkyne cycloaddition strategy, which is often referred to as click chemistry. First, the azide (N3) group, which allows for the preparation of radiolabeled nanoparticles by copper-free click chemistry, was incorporated into glycol chitosan nanoparticles (CNPs). Second, the strained cyclooctyne derivative, dibenzyl cyclooctyne (DBCO) conjugated with a 1,4,7,10-tetraazacyclododecane- 1,4,7,10-tetraacetic acid (DOTA) chelator, was synthesized for preparing the pre-radiolabeled alkyne complex with {sup 64}Cu radionuclide. Following incubation with the {sup 64}Cu-radiolabeled DBCO complex (DBCO-PEG4-Lys-DOTA-{sup 64}Cu with high specific activity, 18.5 GBq/μ mol), the azide-functionalized CNPs were radiolabeled successfully with {sup 64}Cu, with a high radiolabeling efficiency and a high radiolabeling yield (>98%). Importantly, the radiolabeling of CNPs by copper-free click chemistry was accomplished within 30 min, with great efficiency in aqueous conditions. After {sup 64}Cu-CNPs were intravenously administered to tumor-bearing mice, the real time, in vivo biodistribution and tumor-targeting ability of {sup 64}Cu-CNPs were quantitatively evaluated by micro-PET images of tumor-bearing mice.

    The platelet-derived growth factor (PDGF) stimulated the phosphorylation of a nuclear protein of 64 kDa (pp64) in nuclei of nontransformed normal rat kidney (NRK) cells. Low levels of phosphorylation of pp64 were observed in nuclei of serum-starved NRK cells. Fetal calf serum (FCS), PDGF, and homodimeric v-sis and PDGF A-chain protein enhanced the incorporation of 32P into pp64 over 4-fold within 30 min and over 8-fold within 2 h of exposure of NRK cells to the growth factors. In contrast, constitutive phosphorylation of 32P-labeled pp64 in nuclei of NRK cells transformed by the simian sarcoma virus (SSV) was high and only minimally stimulated by PDGF and FCS. 32P-Labeled pp64 was isolated from nuclei of PDGF-stimulated nontransformed NRK cells; the 32P of pp64 was labile in 1 M KOH, and pp64 was not significantly recognized by anti-phosphotyrosine antisera, suggesting that the PDGF-induced phosphorylation of pp64 occurred on serine or on threonine residues. However, pp64 from SSV-transformed NRK cell nuclei was significantly stable to base hydrolysis and was immunoprecipitated with anti-phosphotyrosine antisera, suggesting that pp64 from SSV-transformed cell nuclei is phosphorylated also on tyrosine. FCS, PDGF, and PDGF A- and B-chain homodimers thus stimulate the rapid time-dependent phosphorylation of a 64-kDa nuclear protein shortly after stimulation of responsive cells. The growth factor-stimulated phosphorylation of pp64 and the constitutive high levels of pp64 phosphorylation in cells transformed by SSV suggest important roles for pp64 and perhaps regulated nuclear protein kinases and phosphatases in cell division and proliferation

    Effective specific activity of 64 Cu (amount of radioactivity per µmol metal) is important in order to determine purity of a particular 64 Cu lot and to assist in optimization of the purification process. Metal impurities can affect effective specific activity and therefore it is important to have a simple method that can measure trace amounts of metals. This work shows that ion chromatography (IC) yields similar results to ICP mass spectrometry for copper, nickel and iron contaminants in 64 Cu production solutions. - Highlights: • Comparison of TETA titration, ICP mass spectrometry, and ion chromatography to measure specific activity. • Validates ion chromatography by using ICP mass spectrometry as the “gold standard”. • Shows different types and amounts of metal impurities present in 64 Cu

    In this work, the in vivo behaviour of pure aragonite and vectabone, which is an association of aragonite and an active substance such as gentamicin, was studied to highlight the kinetic resorption of these two biomaterials with 55% of porosity destined for the filling or replacement of bony defects. The synthesis conditions and parameters we used permit us to obtain a biomaterial without a sintering stage. These conditions allow introducing of active substances at the first stage of the elaboration. In this work, the gentamycin antibiotic was associated with calcium carbonate (aragonite 55% with gentamycin) to deliver this active substance on the surgical site for local treatment. The tricalcium phosphate biomaterial was used as the control because of its high biocompatibility. The bony remodelling of these three biomaterials was studied by in vivo experiments. This study was ensured with neutron activation analysis (NAA). The resorption kinetic was elaborated and comparisons of the remodelling biomaterials CaCO 3 55% and CaCO 3 55% with gentamicin (vectabone) and tricalcium phosphate were carried out. The obtained results show that, 6 months after implantation, the mineral composition of vectabone and tricalcium phosphate becomes close to that of young bone. Twelve months after implantation, it becomes similar to that of mature bone

    Objective: To evaluate the influence of heart rate on the image quality of 64-slice spiral computed coronary angiography (MSCTCA) and optimize the image reconstruction window. Methods: According to the heart rate, 86 patients were classified into 5 groups: group A, the heart rate ≤60 beat per minute(BMP); group B,61-70BMP, group C,71-80BMP, and group D>80BMP. The image quality of MSCTCA was scored 5 grades from 1-5 according to heart motion artifact. The influences of heart rate and reconstruction phase on the image quality of MSCTCA were evaluated. Results: Average heart rate was 64.4 ±10.1BMP. Diagnostic image quality (score>3) was attained in 277 of 344 segments at the best reconstruction interval. There was a significant corxelation between average heart rate and image quality, but there was no difference between relative delay (%) reconstruction and absolute delay (ms) reconstruction on the image quality. Conclusion: Reducing average heart rate is beneficial for improving the image quality. (authors)

    Integrin α 4 β 1 (also called very late antigen-4 or VLA-4) plays an important role in tumor growth, angiogenesis and metastasis, and there has been increasing interest in targeting this receptor for cancer imaging and therapy. In this study, we conjugated a peptidomimetic ligand known to have good binding affinity for α 4 β 1 integrin to a cross-bridged macrocyclic chelator with a methane phosphonic acid pendant arm, CB-TE1A1P. CB-TE1A1P-LLP2A was labeled with 64 Cu under mild conditions in high specific activity, in contrast to conjugates based on the “gold standard” di-acid cross-bridged chelator, CB-TE2A, which require high temperatures for efficient radiolabeling. Saturation binding assays demonstrated that 64 Cu-CB-TE1A1P-LLP2A had comparable binding affinity (1.2 nM vs 1.6 nM) but more binding sites (B max = 471 fmol/mg) in B16F10 melanoma tumor cells than 64 Cu-CB-TE2A-LLP2A (B max = 304 fmol/mg, p 64 Cu-CB-TE1A1P-LLP2A had less renal retention but higher uptake in tumor (11.4 ± 2.3 %ID/g versus 3.1 ± 0.6 %ID/g, p 64 Cu-CB-TE2A-LLP2A. At 2 h post-injection, 64 Cu-CB-TE1A1P-LLP2A also had significantly higher tumor:blood and tumor:muscle ratios than 64 Cu-CB-TE2A-LLP2A (CB-TE1A1P = 19.5 ± 3.0 and 13.0 ± 1.4, respectively, CB-TE2A = 4.2 ± 1.4 and 5.5 ± 0.9, respectively, p 64 Cu-CB-TE1A1P-LLP2A is an excellent PET radiopharmaceutical for the imaging of α 4 β 1 positive tumors and also has potential for imaging other α 4 β 1 positive cells such as those of the pre-metastatic niche

    Full Text Available Background. Recent studies showed that depression was an independent predictor of mortality from cardio-vascular disease in healthy women. Objective. To explore the effect of depression (D on relative risk (RR of myocardial infarction (MI and stroke for 16 years (1995–2010 in the female population aged 25–64 years from Novosibirsk, Russia. Materials and methods. Under the third screening of the WHO “MONICA-psychosocial” (MOPSY programme, a cohort of women aged 25–64 years (N=560 was surveyed. Women were followed for 16 years for the incidence of MI and stroke (1995–2010. D was measured at the baseline examination by means of test “MOPSY”. Participants having stroke, MI, arterial hypertension, coronary artery diseases and diabetes in their medical history at the baseline were excluded from this analysis. Results. The prevalence of D in women aged 25–64 years was 55.2%. With the growth of D levels, positive self-rated health reduced and almost 100% of those women have complaints about their health, but considered the care of their health insufficient. Women with major D significantly extended negative behavioural habits: smoking and unsuccessful attempts to give up, low physical activity, and less likely to follow a diet (healthy food. Major D associated with high job strain and family stress. Relative risk (RR of MI development in women with D during 16 years of study was higher in 2.53 cases (p<0.05 and risk of stroke was higher in 4.63 cases (p<0.05. Conclusions. The prevalence of D in women aged 25–64 years was >50%. Women with D had a 2.53-fold risk of MI and 4.63-fold risk of stroke during the 16 years of follow-up.

    Mesoporous silica, MCM-41, functionalized with 3-aminopropyltriethoxysilane (APTES) was investigated as a potential drug delivery system, using [(64)Cu]-5, 10, 15, 20-tetrakis penta fluorophenyl porphyrin complex. [(64)Cu]-TPPF20 complex was grafted on functionalized MCM-41. The product was characterized by paper chromatography, FTIR spectroscopy, low angle X-ray diffraction, CHN and TGA/DTA analyses and atomic force microscopy. The biological evaluations of the grafted complex, [(64)Cu]-TPPF20@NH2-MCM-41, were done in Fibrosarcoma tumor-bearing Sprague-Dawley rats using scarification studies and Sopha DST-XL Dual-Head SPECT system. The actual loading amount of aminopropyl groups was found about 1.6mmol per gram of final silica. The specific activity of the final compound was found to be 3Ci/g. Amine functionalized MCM-41 was found to be a good platform for theranostic radiopharmaceuticals such as copper-64 complexes. Considering the accumulation of the tracer in tumor cells, fast wash-out from normal tissues, the short half-life copper-64 and less imposed radiation doses to patients, [(64)Cu]-TPPF20@NH2-MCM-41 can potentially be a suitable candidate for tumor imaging applications and future PET studies.

    Laser shock peening of titanium 6-4 has been shown to improve its high cycle fatigue life. Residual compressive stresses generated on the surface of titanium 6-4, as a result of laser shocking, have shown dramatic improvement in the performance of aircraft turbine blades. Laser shocking of titanium was carried out with a 20 ns pulse width, 50 joule pulsed laser, operated by LSP Technologies, Columbus, OH. Titanium disks, 20-mm in diameter, and ranging in thicknesses from zero (bare LiF) to 3-mm were subjected to laser shock to monitor amplitude and temporal stress profiles of the pulsed laser. Laser shock stress amplitudes on the back of titanium disks were monitored with VISAR using LiF as the window material. The peak shock stress produced in LiF (titanium thickness zero) was measured to be 16±1 GPa. The laser shock amplitude decays to about 2.7 GPa while propagating through 3-mm thick disk of titanium 6-4

    Ligand L{sup 1}, based on a pyridine scaffold, functionalized by two bis(methane phosphonate)aminomethyl groups, was shown to display a very high affinity towards Cu(II) (log K{sub CuL}=22.7) and selectivity over Ni(II), Co(II), Zn(II) and Ga(III) ({delta} log K{sub ML}>4) as shown by the values of the stability constants obtained from potentiometric measurements. Insights into the coordination mode of the ligand around Cu(II) cation were obtained by UV-Vis absorption and EPR spectroscopies as well as density functional theory (DFT) calculations (B3LYP model) performed in aqueous solution. The results point to a pentacoordination pattern of the metal ion in the fully deprotonated [CuL{sup 1}]{sup 6-} species. Considering the beneficial thermodynamic parameters of this ligand, kinetic experiments were run to follow the formation of the copper(II) complexes, indicating a very rapid formation of the complex, appropriate for {sup 64}Cu complexation. As L{sup 1} represents a particularly interesting target within the frame of {sup 64}Cu PET imaging, a synthetic protocol was developed to introduce a labeling function on the pyridyl moiety of L{sup 1}, thereby affording L{sup 2}, a potential bifunctional chelator (BFC) for PET imaging.

    To identify socio-demographic and lifestyle determinants of weight gain in a sample of premenopasual black South African (SA) women. Changes in body composition (dual-energy X-ray absorptiometry, computerised tomography), socio-economic status (SES) and behavioural/lifestyle factors were measured in 64 black SA women at baseline (27 ± 8 years) and after 5.5 years. A lower body mass index (BMI) and nulliparity, together with access to sanitation, were significant determinants of weight gain and change in body fat distribution over 5.5 years. In addition, younger women increased their body weight more than their older counterparts, but this association was not independent of other determinants. Further research is required to examine the effect of changing SES, as well as the full impact of childbearing on weight gain over time in younger women with lower BMIs. This information will suggest areas for possible intervention to prevent long-term weight gain in these women.

    Pneumonia is the principal cause of morbidity and mortality in PEMEX medical services. Vaccination against influenza is 72% effective in preventing hospitalizations and 87% effective in preventing deaths related to this virus, and vaccination against pneumococcus is 60% effective in preventing invasive diseases by this microorganism. ACIP recommends use of both vaccines simultaneously in adults over 65 years of age. To describe the frequency, duration and severity of local and systemic reactions related to the simultaneous administration of vaccines against influenza and pneumococcus in adults over 55 years of age, and compare with reactions related to influenza vaccine. Two hundred-thirty two adults over 55 years of age were randomly assigned to two groups, group A (114 subjects) received influenza vaccine, group B (118 subjects) received influenza and pneumococcus vaccines simultaneously. Comparing the number of subjects with local reactions on the right arm between groups A and B (17 subjects vs. 27 subjects), differences were not statistically significative (p = 0.121). Systemic reactions were not statistically significative either (p = 0.126) when results were compared between both groups (30 from group A vs. 42 for group B). Simultaneous administration of influenza and pneumococcus vaccines has proven to be safety. In the absence of contraindications, there is no reason for not offering both vaccines in the same medical visit.

    Kawasaki disease (KD) is a systemic vasculitis that mainly affects coronary arteries in children, and requires regular follow-up from the time of diagnosis. To evaluate the feasibility of 64-slice CT angiography (CTA) for follow-up of patients with KD using previously performed invasive catheter coronary angiography (CCA) as reference standard. The study group comprised 12 patients (age 17.6 {+-} 2.9 years, mean{+-}SD) with a diagnosis of KD and a previously performed CCA (interval, 32.6 {+-} 13.5 months) who underwent 64-slice cardiac CTA. The quality of the images for establishing the presence of coronary abnormalities was determined by two observers. The CTA findings were compared with those from the prior CCA. Adequate image quality was obtained in all patients. Mean effective dose for CTA was 6.56 {+-} 0.95 mSv. CTA allowed accurate identification, characterization and measurement of all coronary aneurysms (n = 32), stenoses (n = 3) and occlusions (n = 9) previously demonstrated by CCA. One patient with disease progression went on to have percutaneous coronary intervention. Coronary lesions were reliably evaluated by 64-slice CTA in the follow-up of compliant patients with KD, reducing the need for repeated diagnostic invasive CCA. Hence, in an adequately selected patient population, the role of CCA could be limited almost only to therapeutic procedures. (orig.)

    2009-01-01

    Background: Due to great technological progress made over the last decade in computer tomography, CT Has become a very successful tool for diagnostic imaging in polytraumatic patients. The purpose of this study is an optimum selection of parameters to detect all post-traumatic pathologies in polytraumatic patients, with the application of minimum ionizing radiation. Material/Methods: 131 patients with a suspected polytrauma were studied following various scanning patterns with a 64-slice CT of the head, neck, thorax and abdominal cavity with pelvis. The patients were divided into three groups in accordance with the chosen scheme. Materials were analyzed with the following in view: increasing the efficacy of detecting pathologies, decreasing radiation dose, simplifying assessment and facilitating image archiving. Results: The following mean numbers of serious post-traumatic pathologies were diagnosed during one examination: group I - 1.8, group II - 2.8, and group III - 2.1. There was a statistically significant reduction in the number of reconstructions performed during one examination from 11.8 in group I, 8.3 in group II, to 7.2 in group III. Additionally, statistically significant reductions were obtained in the mean values of the dose-length product (DLP): 3361 mGy · cm (group I), 2805 mGy 8· cm (group II), 2583 mGy · cm (group III). Conclusions: The third scanning pattern, which comprised multiple adjacent sections scanned jointly, including a single trunk scan following the administration of a contrast material, is best in terms of evaluation comfort and the lowest radiation dose absorbed by the patient. Patterns II and III are most effective in detecting pathologies. (authors)

    Decreased expression or function of UCP3 (uncoupling protein 3) could reduce energy expenditure and increase the storage of energy as fat. Some studies have pointed to a role of UCP3 in the regulation of whole body energy homeostasis, diet induced obesity, and regulation of lipids as metabolic substrates. The C/C genotype of a polymorphism in the UCP3 promoter (-55C-->T) is associated with an increased expression of UCP3 mRNA in muscle. The aim of our study was to investigate the influence of -55CT polymorphism of UCP3 gene on adipocytokines response and weight loss secondary to a hypocaloric diet in obese patients. A population of 107 obese (body mass index >30) nondiabetic outpatients was analyzed in a prospective way. Before and after three months of a hypocaloric diet, an indirect calorimetry, tetrapolar electrical bioimpedance, blood pressure, a serial assessment of nutritional intake with 3-day written food records, and biochemical analysis were performed. The lifestyle modification program consisted of a hypocaloric diet (1520 kcal, 52% of carbohydrates, 25% of lipids and 23% of proteins). The exercise program consisted of aerobic exercise for at least 3 times per week (60 minutes each). The mean age was 49.5+/-34.5 years and the mean BMI 34.5+/-4.8, with 27 males (25.3%) and 80 females (74.7%). Ninety patients (25 males/65 females) (83.6%) had the genotype 55CC (wild group) and 17 patients (2 male/15 females) (16.4%) 55CT (mutant group). The percentage of responders (weight loss) was similar in both groups (wild group: 84.7% vs. mutant group: 81.8%). BMI, weight, fat mass, systolic blood pressure, LDL cholesterol, waist circumference, and waist-to-hip ratio decreased in the wild group and RMR and VO (2) were increased. In the mutant group, BMI and weight decreased. Leptin and IL-6 levels have a significant decrease in the wild group (9.6%: p<0.05) and (30.5%: p<0.05), respectively. Patients with -55CC genotype have a significant decrease in leptin

    The dietary exposure to the sum of the six indicator PCBs (Σ6 PCBs; PCB 28, 52, 101, 138, 153, and 180) across different Austrian population groups was assessed in this study by combining data on occurrence from food of the Austrian market (n=157) analysed during 2006-2011 with national food consumption data. The most contaminated food group was meat, poultry, game and offal with average levels of ndl-PCBs of 5.20 ng g(-1) fat. In fish and fish products and eggs, mean concentrations of 3.89 ng g(-1) fresh weight (fw) and 4.00 ng g(-1) fat, respectively, were found. In milk and dairy products average concentrations ranged from 3.07 to 4.44 ng g(-1) fat. The mean dietary intake of Σ6 PCBs was estimated to be 3.37 ng kg(-1) bw d(-1) for children (6-15 years old), 3.19 ng kg(-1) bw d(-1) for women (19-65 years) and 2.64 ng kg(-1) bw d(-1) for men (19-65 years). In all three population groups, milk and dairy products was the major contributing food group to the total dietary intake (50-55%) followed by fish and fish products (23-27%). The exposure of all Austrian population groups is well below the tolerable daily intake (TDI) of 10 ng kg(-1) bw d(-1) proposed by WHO, accounting for 34% in children, 32% in women and 26% in men.

    NASA is developing technology for 64 64-ary PPM using relatively large PPM time slots (10 ns) an and relatively simple d electronic electronic-based receiver logic. In this paper we describe photonic photonics-based receiver options for the case of much higher data rates and inherently shorter decision times. The receivers take the form of virtual ( array or quadrant) arrays with associated comparison tests. Previously we explored this concept for 4-ary and 16-ary PPM at data rates of up to 10 Gb/s. The lessons learned are applied to the case of 64 64-ary PPM at 1.25 Gb/s s. Various receiver designs are compare, and t the optimum design, based on virtual array he arrays, is s, evaluated using numerical simulations.

    Bifunctional chelators have been shown to impact the biodistribution of monoclonal antibody (mAb)-based imaging agents. Recently, radiolabeled 1,4,7-triazacyclononane,1-glutaric acid-4,7-acetic acid (NODAGA)-peptide complexes have demonstrated improved in vivo stability and performance compared to their 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) counterparts. Here, we investigated if similar utility could be achieved with mAbs and compared (64)Cu-labeled DOTA and NODAGA-immunoconjugates for the detection of epithelial cell adhesion molecule (EpCAM) in a prostate cancer model. DOTA and NODAGA-immunoconjugates of an EpCAM targeting mAb (mAb7) were synthesized and radiolabeled with (64)Cu (DOTA: 40°C for 1hr; NODAGA: 25°C for 1hr). The average number of chelators per mAb was quantified by isotopic dilution, and the biological activity of the immunoconjugates was evaluated by flow cytometry and ELISA. Radioligand assays were performed to compare cellular uptake and determine the dissociation constant (Kd) and maximum number of binding sites (Bmax) for the immunoconjugates using DsRed-transfected PC3-cells. A PC3-DsRed xenograft tumor model was established in nude mice and used to perform biodistribution studies to compare organ uptake and pharmacokinetics. (64)Cu-DOTA-mAb7 and (64)Cu-NODAGA-mAb7 were prepared with chelator/protein ratios of 2-3 and obtained in comparable radiochemical yields ranging from 59 to 71%. Similar immunoreactivity was observed with both agents, and mock labeling studies indicated that incubation at room temperature or 40°C did not affect potency. (64)Cu-NODAGA-mAb7 demonstrated higher in vitro cellular uptake while (64)Cu-DOTA-mAb7 had higher Kd and Bmax values. From the biodistribution data, we found similar tumor uptake (13.44±1.21%ID/g and 13.24±4.86%ID/g for (64)Cu-DOTA-mAb7 and (64)Cu-NODAGA-mAb7, respectively) for both agents at 24hr, although normal prostate tissue was significantly lower for (64)Cu-NODAGA-mAb7

    For nuclides with a large number of resonances the covariance matrix of resonance parameters can become very large and expensive to process in terms of the computation time. By converting covariance matrix of resonance parameters into covariance matrices of background cross-section in a more or less coarse group structure a considerable amount of computer time and memory can be saved. The question is how important is the information that is discarded in the process. First, the uncertainty of the 55 Mn resonance integral was estimated in narrow resonance approximation for different levels of self-shielding using Bondarenko method by random sampling of resonance parameters according to their covariance matrices from two different 55 Mn evaluations: one from Nuclear Research and Consultancy Group NRG (with large uncertainties but no correlations between resonances), the other from Oak Ridge National Laboratory (with smaller uncertainties but full covariance matrix). We have found out that if all (or at least significant part of the) resonance parameters are correlated, the resonance integral uncertainty greatly depends on the level of self-shielding. Second, it was shown that the commonly used 640-group SAND-II representation cannot describe the increase of the resonance integral uncertainty. A much finer energy mesh for the background covariance matrix would have to be used to take the resonance structure into account explicitly, but then the objective of a more compact data representation is lost.

    To observe the short and long-term efficacy of quick repositioning maneuver for posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV) in different age groups. The clinical data of 113 adult patients with single PC-BPPV who underwent quick repositioning maneuver from July 2009 to February 2015 were retrospectively analyzed. The quick repositioning maneuver was to roll the patient from involved side to healthy side in the coronal plane for 180° as quickly as possible. The patients were divided into 3 groups according to different ages: young group (age group (45 ≤ age group (≥ 60 years). The short and long term outcomes of the three groups were observed. The left ear was involved in 58 cases (51.3%) and the right ear in 55 cases (48.7%). The short term improvement rates of the young, middle-age and the old groups were 92.5%, 93.6% and 92.3% respectively, and the long term improvement rate was 90.0%, 85.1% and 73.1% respectively. There was no significant difference among the three groups in short and long term outcomes (P > 0.05). The recurrence rate of the three groups was 5.0%, 6.4% and 15.4% respectively, also no significant difference (P > 0.05). The quick repositioning maneuver along the coronal plane for PC-BPPV has a definite effect for every age groups. The method is simple, rapid and easy to master, and the patients are tolerated the maneuver well without evident side effect.

  15. Lack of Association of CD55 Receptor Genetic Variants and Severe Malaria in Ghanaian Children

    Full Text Available In a recent report, the cellular receptor CD55 was identified as a molecule essential for the invasion of human erythrocytes by Plasmodium falciparum, the causal agent of the most severe form of malaria. As this invasion process represents a critical step during infection with the parasite, it was hypothesized that genetic variants in the gene could affect severe malaria (SM susceptibility. We performed high-resolution variant discovery of rare and common genetic variants in the human CD55 gene. Association testing of these variants in over 1700 SM cases and unaffected control individuals from the malaria-endemic Ashanti Region in Ghana, West Africa, were performed on the basis of single variants, combined rare variant analyses, and reconstructed haplotypes. A total of 26 genetic variants were detected in coding and regulatory regions of CD55. Five variants were previously unknown. None of the single variants, rare variants, or haplotypes showed evidence for association with SM or P. falciparum density. Here, we present the first comprehensive analysis of variation in the CD55 gene in the context of SM and show that genetic variants present in a Ghanaian study group appear not to influence susceptibility to the disease.

    The use of copper radioisotopes in imaging and therapy applications has created a greater need for bifunctional chelates (BFCs) for complexing copper radioisotopes to biomolecules. It has been demonstrated that the charge and lipophilicity of the Cu-BFC complex has a significant effect on the in vivo behavior of the radiolabeled Cu-BFC-biomolecule conjugate. To evaluate the effects of charge, stability, and macrocyclic backbone size on the biological behavior of 64 Cu complexes, a series of macrocyclic 64 Cu complexes have been prepared, and the biodistributions of these agents were evaluated in normal Sprague-Dawley rats. Two macrocyclic backbones, dodecane and tetradecane, were evaluated; cyclen, DOTA, and DO2A were dodecane backbone derivatives, and cyclam, TETA, and et-cyclam were tetradecane backbone derivatives. The biodistributions of the 64 Cu-labeled complexes correlated with differences in the size of the macrocycle backbone and the formal charge of the complex. All compounds showed uptake and clearance through the liver and kidneys; however, the positively charged 64 Cu complexes showed significantly higher uptake in both of these organs than did the negatively charged or neutral complexes. 64 Cu-TETA, a negatively charged complex with the tetradecane backbone, had the most efficient clearance by 24 hours' postinjection. These data suggest that negatively charged complexes may have more favorable clearance properties when used as BFCs

    Accidents represent a significant health problem for elderly people. The objective of this study was to assess the incidence of accidents in over-64-year-olds in the Basque Country population, and to describe the clinical-epidemiological features leading to them. This was a prospective cohort study of 15,192 non-institutionalised individuals over 64 years of age, conducted under the auspices of the Basque Sentinel Practice Network (Red Vigía) over one year. A questionnaire was completed for each accident. The rates and risks of accidents were calculated by sex and age group of the individuals who had the accidents. The rates of accidents were 46.52 and 81.87 per 1000 men and women, respectively. The most common type of accident was a fall (92%), and the most severe injuries were fractures (17%), with the risk of an accident being significantly higher in women and in the over-75-year-olds. These data reflect the scale of accidents in over-64-year-olds in the Basque Country. The most frequent accident was the fall, which represents a dramatic event among the elderly, being one of the main causes of injury, disability and institutionalisation among this population group.

    2009-01-01

    We sought to investigate the performance of 64-slice CT in symptomatic patients with different coronary calcium scores. Two hundred patients undergoing 64-slice CT coronary angiography for suspected coronary artery disease were enrolled into five groups based on Agatston calcium score using the Mayo Clinic risk stratification: group 1: score 0, group 2: score 1-10, group 3: score 11-100, group 4: score 101-400, and group 5: score > 401. Diagnostic accuracy for the detection of significant (≥50% lumen reduction) coronary artery stenosis was assessed on a per-segment and per-patient base using quantitative coronary angiography as the gold standard. For groups 1 through 5, sensitivity was 97, 96, 91, 90, 92%, and specificity was 99, 98, 96, 88, 90%, respectively, on a per-segment basis. On a per-patient basis, the best diagnostic performance was obtained in group 1 (sensitivity 100% and specificity 100%) and group 5 (sensitivity 95% and specificity 100%). Progressively higher coronary calcium levels affect diagnostic accuracy of CT coronary angiography, decreasing sensitivity and specificity on a per-segment base. On a per-patient base, the best results in terms of diagnostic accuracy were obtained in the populations with very low and very high cardiovascular risk. (orig.)

    2008-01-01

    Objective: To assess the feasibility of using an automatic tube current modulation (ATCM) method to obtain consistent image quality with reduced radiation dose for young children undergoing chest scans with a set of 64-slice spiral CT. Methods: Fifty young children underwent chest scans on a GE 64-slice VCT with automatic tube current modulation. The noise index (NI) for this study group was set to 8 or 9 based on the proposed reference for pediatric chest imaging in our hospital. We compared image quality and radiation dose for the study group with the age-matched control group of 50 young children acquired with standard protocol of fixed-mAs (120 and 150 mAs for under 1 and above 1 year old, respectively). The volume CT dose index(CTDIvol) values were recorded for both groups. Two experienced pediatric radiologists assessed image quality on a 5-point scale with 5 being the best. Scores greater than or equal to 3 were considered clinically acceptable. The degree of interobserver concordance was determined by Kappa statistics. Results: The average objective image noise and CTDIvol for control group was (4.78±0.58) and (6.68±0.62) mGy, respectively. For the study group the mean value of objective mAs was (41.6±11.6) (20-79 mAs) with mean CTDIvol of (2.34±0.71) mGy, and the use of ATCM produced mean noise of (7.84±0.66). The average CTDIvol with the use of NI of 8-9 was about 65% lower than that with the fixed mAs setting. The mean image quality score for the study group and control group was (3.46±0.40) and (4.65±0.46) respectively. All studies had acceptable image quality, and there was good inter-observer agreement in diagnostic acceptability (Kappa=0.474 and 0.536). Conclusion: The automatic tube current modulation method could be used to obtain consistent image quality for young children undergoing 64-slice MSCT chest scans. With proper noise level setting (NI=8 or 9), one may obtain clinically acceptable images with much reduced radiation dose. (authors)

    In this study, (64)Cu-NOTA-TRC105 (TRC105 is an anti-CD105 monoclonal antibody that binds to both human and murine CD105) positron emission tomography (PET) was used to assess the response to pravastatin treatment in a murine model of peripheral artery disease (PAD). Hindlimb ischemia was induced by ligation of the right femoral arteries in BALB/c mice under anesthesia, and the left hindlimb served as an internal control. Mice in the treatment group were given intraperitoneal pravastatin daily until the end of the study, whereas the animals in the control group were injected with 0.9% sodium chloride solution. Laser Doppler imaging showed that blood flow in the ischemic hindlimb plummeted to ~20% of the normal level after surgery, and gradually recovered to near normal level on day 10 in the treatment group and on day 20 in the control group. Angiogenesis was non-invasively monitored and quantified with (64)Cu-NOTA-TRC105 PET on postoperative days 3, 10, 17, and 24. Tracer uptake at 48 h post-injection in the ischemic hindlimb in the treatment group was significantly higher than that of the control group on day 10 (20.5 ± 1.9 %ID/g vs 11.4 ± 1.5 %ID/g), suggesting increased CD105 expression and higher level of angiogenesis upon pravastatin treatment, and gradually decreased to background levels in both groups (4.9 ± 0.8 %ID/g vs 3.4 ± 1.9 %ID/g on day 24). The in vivo PET data correlated well with ex vivo biodistribution studies performed on day 24. Increased CD105 expression on days 3 and 10 following ischemia was further confirmed by immunofluorescence staining. Taken together, our results indicated that (64)Cu-NOTA-TRC105 PET is a suitable and non-invasive method to monitor the angiogenesis and therapeutic response in PAD, which can also be utilized for non-invasive evaluation of other pro-angiogenic/anti-angiogenic drugs in other cardiovascular diseases and cancer.

  17. Are we getting healthier as we grow older? Implications for babyboomer labor force participation.

    Schofield, Deborah J; Passey, Megan E; Earnest, Arul; Gloor, Ian C; Shrestha, Rupendra

    2007-10-01

    The Intergenerational Report (IGR) released by the Department of the Treasury of the Commonwealth of Australia in 2002 highlighted pressures that in the future would threaten the sustainability of the Australian government's budget balance. These pressures result from the growing needs of an aging population and labor shortages that will limit economic growth and taxation revenue. The IGR has become a driving force in planning government policy. The Treasurer has recently said that "the whole economic agenda of the government at the moment is drawn from the IGR." In response, the Prime Minster and Treasurer have promoted deferred or gradual retirement as part of the solution. However, about 50% of men and 20% of women retire early as a result of ill health, indicating that poor health is potentially a limiter of economic growth. This paper reports lower labor force participation among persons with poorer health and that these persons move out of the labor force at a faster rate as they age. A range of measures suggests some decline in health in the pre-retirement age group (those aged from 40 to 64 years). This indicates that better health may be a facilitator of greater labor force participation in the baby boomer cohort. However, there is evidence that improving economic conditions in Australia leading to low unemployment has created an environment more favorable to the employment of older workers with health problems as there has been a rise in labor force participation in these groups, and measures to prevent chronic disease may further increase the employment prospects.

  18. Radiography imaging by 64 and 128 micro-strips crystalline detectors at different X-ray energies

    2006-01-01

    This paper summarizes some results obtained in the evaluation of the performance of position sensitive detectors in track reconstruction in particle physics experiments. Crystalline silicon micro-strips detectors with 64 and 128 channels and 100 μm pitch were used to obtain radiographic digital images of different objects. The more relevant figures for spectrometry applications were measured and reported. Two-dimensional images were obtained by scanning the object with a collimated beam using different source-target-detector positioning and three sources of X-rays (8.04, 18.55 and 22.16 keV). The counts acquired by each strip correspond to a particular collimator position during the scan, thus serving to reconstruct the image of the exposed to X-ray object and to reveal its internal structure. The use of some techniques for image processing allow the further improvement of the radiography quality. The preliminary results obtained using in-house made and accreditation mammography phantoms allow to infer that such detectors can be successfully introduced in the digital mammography practice.

    The (6-4) photoproduct is one of the major damaged bases produced by ultraviolet light in DNA. This lesion is known to be alkali-labile, and strand breaks occur at its sites when UV-irradiated DNA is treated with hot alkali. We have analyzed the product obtained by the alkali treatment of a dinucleoside monophosphate containing the (6-4) photoproduct, by HPLC, NMR spectroscopy, and mass spectrometry. We previously found that the N3-C4 bond of the 5' component was hydrolyzed by a mild alkali treatment, and the present study revealed that the following reaction was the hydrolysis of the glycosidic bond at the 3' component. The sugar moiety of this component was lost, even when a 3'-flanking nucleotide was not present. Glycosidic bond hydrolysis was also observed for a dimer and a trimer containing 5-methyl-2-pyrimidinone, which was used as an analog of the 3' component of the (6-4) photoproduct, and its mechanism was elucidated. Finally, the alkali treatment of a tetramer, d(GT(6-4)TC), yielded 2'-deoxycytidine 5'-monophosphate, while 2'-deoxyguanosine 3'-monophosphate was not detected. This result demonstrated the hydrolysis of the glycosidic bond at the 3' component of the (6-4) photoproduct and the subsequent strand break by β-elimination. It was also shown that the glycosidic bond at the 3' component of the Dewar valence isomer was more alkali-labile than that of the (6-4) photoproduct.

    Health literacy is of increasing importance in public health research. It is a necessary pre-condition for the involvement in decisions about health and health care and related to health outcomes. Knowledge about limited health literacy in different age groups is crucial to better target public health interventions for subgroups of the population. However, little is known about health literacy in Germany. The study therefore assesses the prevalence of limited health literacy and associated factors among different age groups. The Health Literacy Survey Germany is a cross-sectional study with 2,000 participants aged 15 years or older in private households. Perceived health literacy was assessed via computer-assisted personal interviews using the HLS-EU-Q-47 questionnaire. Descriptive analyses, chi-square tests and odds ratios were performed stratified for different age groups. The population affected by limited perceived health literacy increases by age. Of the respondents aged 15-29 years, 47.3 % had limited perceived health literacy and 47.2 % of those aged 30-45 years, whereas 55.2 % of the respondents aged 46-64 years and 66.4 % aged 65 years and older showed limited perceived health literacy. In all age groups, limited perceived health literacy was associated with limited functional health literacy, low social status, and a high frequency of doctor visits. The results suggest a need to further investigate perceived health literacy in all phases of the life-course. Particular attention should be devoted to persons with lower social status, limited functional health literacy and/or a high number of doctor visits in all age groups.

    Photolyases can repair pyrimidine dimers on the DNA that are formed during UV irradiation. PhrB from Agrobacterium fabrum represents a new group of prokaryotic (6-4) photolyases which contain an iron-sulfur cluster and a DMRL chromophore. We performed site-directed mutagenesis in order to assess the role of particular amino acid residues in photorepair and photoreduction, during which the FAD chromophore converts from the oxidized to the enzymatically active, reduced form. Our study showed that Trp342 and Trp390 serve as electron transmitters. In the H366A mutant repair activity was lost, which points to a significant role of His366 in the protonation of the lesion, as discussed for the homolog in eukaryotic (6-4) photolyases. Mutants on cysteines that coordinate the Fe-S cluster of PhrB were either insoluble or not expressed. The same result was found for proteins with a truncated C-terminus, in which one of the Fe-S binding cysteines was mutated and for expression in minimal medium with limited Fe concentrations. We therefore assume that the Fe-S cluster is required for protein stability. We further mutated conserved tyrosines that are located between the DNA lesion and the Fe-S cluster. Mutagenesis results showed that Tyr424 was essential for lesion binding and repair, and Tyr430 was required for efficient repair. The results point to an important function of highly conserved tyrosines in prokaryotic (6-4) photolyases.

    The objective was to identify lung abnormalities in patients with esophageal cancer, to compare the obtained data and to demonstrate its relationship with smoking. This was a series of cases type of cross-sectional study. We studied 55 patients with esophageal carcinoma diagnosed between 1998 and 2001 at Hospital de Base de Sao Jose do Rio Preto, SP, Brazil. Chest plain films and computed tomography scans were analyzed. The frequency of the tumors and other lung abnormalities in two groups of patients were compared: smokers and non-smokers. The results showed that forty-six (83%) patients had spinous cell carcinoma, seven (13%) adenocarcinomas, one (2%) carcinoma of small cells and one (2%) non-Hodgkin lymphoma. Forty-eight (87%) patients were smokers and seven (13%) were non-smokers. In the smokers group, 89% had spinous cell carcinoma, 9% adenocarcinoma and 2% small cells carcinoma. In the non-smokers group, 57% had adenocarcinoma, 28% spinous cell carcinoma and 15% non-Hodgkin lymphoma. Metastases were identified in four smokers and in two non-smokers. The prevalence of the lung abnormalities (interstitial infiltration, emphysema and pneumonia) was higher in the smokers group (73%) than in the non-smokers group (27%) (p = 0.03). We concluded that this fact reinforces the importance of evaluation of the lungs in patients with esophageal neoplasms. (author)

    Until now stenoses of the coronary arteries have been evaluated visually with CT angiography. Therefore, the results were highly dependent on subjective factors inherent in the examiner. New software tools for semiquantitative analysis (CT-QCA, quantitative coronary assessment) might be adequate to improve the diagnostic accuracy und reproducibility. CTAs of 20 patients were analyzed. Ten patients each were evaluated using 64-slice CT (64SCT) and dual source CT (DSCT) (Somatom Sensation 64 and Somatom Definition, Siemens Medical Solutions, Forchheim), respectively. Two radiologists independently evaluated the data visually and with the help of a software tool (Syngo Circulation, Siemens Medical Solutions, Forchheim). The results of the quantitative assessment of the invasive heart catheterization served as the reference standard. Sensitivity and specificity as well as the correlation coefficient, the systematic error, and the interobserver agreement (kappa) were determined. In each of both patient groups 12 stenoses were detected. For the detection of stenoses >75%, sensitivity and specificity for the visual evaluation using the 64SCT were 100% and 90%, and with the CT-QCA both were 100%. For the DSCT sensitivity and specificity were 100% for both the visual and semiautomated evaluation. The Bland-Altman plot of the results of the 64SCT showed an overestimation of 3.3% (±62.7%/56.2%) compared to the heart catheterization. The results of the DSCT exhibited an overestimation of 6.2% (±33.1%/19.8%). The interobserver agreement of the CT-QCA and the visual evaluation showed a kappa value of 0.75 and for DSCT of 1.0. The results showed a good correlation of grading stenosis between the software-assisted evaluation and the results of the coronary catheter angiography. The promising results of the DSCT are due to a superior temporal resolution compared to the 64SCT. Confirmation of these data by trials in larger patient collectives is warranted. (orig.) [de

    The purpose of this study was to investigate the possibility of assessing the underlying respiratory disease as well as cardiac function during ECG-gated CT angiography of the chest with 64-slice multidetector-row CT (MDCT). One hundred thirty-three consecutive patients in sinus rhythm with known or suspected ventricular dysfunction underwent an ECG-gated CT angiographic examination of the chest without β-blockers using the following parameters: (1) collimation: 32 x 0.6 mm with z-flying focal spot for the acquisition of 64 overlapping 0.6-mm slices (Sensation 64; Siemens); rotation time: 0.33 s; pitch: 0.3; 120 kV; 200 mAs; ECG-controlled dose modulation (ECG-pulsing) and (2) 120 ml of a 35% contrast agent. Data were reconstructed: (1) to evaluate the underlying respiratory disease (1-mm thick lung and mediastinal scans reconstructed at 55% of the R-R interval; i.e., ''morphologic scans'') and (2) to determine right (RVEF) and left (LVEF) ventricular ejection fractions (short-axis systolic and diastolic images; Argus software; i.e., ''functional scans''). The mean heart rate was 73 bpm (range: 42-120) and the mean scan time was 18.11±2.67 s (range: 10-27). A total of 123 examinations (92%) had both lung and mediastinal images rated as diagnostic scans, whereas 10 examinations (8%) had non-diagnostic images altered by the presence of respiratory-motion artifacts (n=4) or cyclic artifacts related to the use of a pitch value of 0.3 in patients with a very low heart rate during data acquisition (n=6). Assessment of right and left ventricular function was achievable in 124 patients (93%, 95% CI: 88-97%). For these 124 examinations, the mean RVEF was 46.10% (±9.5; range: 20-72) and the mean LVEF was 58.23% (±10.88; range: 20-83). In the remaining nine patients, an imprecise segmentation of the right and left ventricular cavities was considered as a limiting factor for precise calculation of end-systolic and end-diastolic ventricular volumes. The mean (±SD) DLP

    Full Text Available Background and Objectives. Migraine is a multifactorial common neurovascular disease with a polygenic inheritance. Inflammation plays an important part in migraine pathophysiology. C-C chemokine receptor 2 (CCR2 is an important chemokine for monocyte aggregation and transendothelial monocyte migration. The aim of our study was to investigate the association of migraine with CCR2V64Il polymorphism in the Iranian population. Methods. We assessed 103 patients with newly diagnosed migraine and 100 healthy subjects. Genomic DNA samples were extracted from peripheral blood and genotypes of CCR2V64Il gene polymorphism were determined. For measuring the severity of headache, every patient filled out the MIGSEV questionnaire. Results. There were no significant differences in the distribution of both 64Il allele and heterozygote (GA genotype of CCR2 gene polymorphism (P=0.396; OR=0.92, 95% CI = 0.50–1.67 and P=0.388; OR=0.91, 95% CI = 0.47–1.73, resp. between case and control groups. There was no significant difference of alleles frequency between three grades of MIGSEV (P=0.922. Conclusions. In conclusion our results revealed no association between CCR2V64Il polymorphism and susceptibility to migraine and also headache severity in the Iranian population.

    Introduction: 123 I-NKJ64, a reboxetine analogue, is currently under development as a potential novel single photon emission computed tomography radiotracer for imaging the noradrenaline transporter in brain. This study describes the development of the radiosynthesis of 123 I-NKJ64, highlighting the advantages and disadvantages, pitfalls and solutions encountered while developing the final radiolabelling methodology. Methods: The synthesis of 123 I-NKJ64 was evaluated using an electrophilic iododestannylation method, where a Boc-protected trimethylstannyl precursor was radioiodinated using peracetic acid as an oxidant and deprotection was investigated using either trifluoroacetic acid (TFA) or 2 M hydrochloric acid (HCl). Results: Radioiodination of the Boc-protected trimethylstannyl precursor was achieved with an incorporation yield of 92±6%. Deprotection with 2 M HCl produced 123 I-NKJ64 with the highest radiochemical yield of 98.05±1.63% compared with 83.95±13.24% with TFA. However, the specific activity of the obtained 123 I-NKJ64 was lower when measured after using 2 M HCl (0.15±0.23 Ci/μmol) as the deprotecting agent in comparison to TFA (1.76±0.60 Ci/μmol). Further investigation of the 2 M HCl methodology found a by-product, identified as the deprotected proto-destannylated precursor, which co-eluted with 123 I-NKJ64 during the high-performance liquid chromatography (HPLC) purification. Conclusions: The radiosynthesis of 123 I-NKJ64 was achieved with good isolated radiochemical yield of 68% and a high specific activity of 1.8 Ci/μmol. TFA was found to be the most suitable deprotecting agent, since 2 M HCl generated a by-product that could not be fully separated from 123 I-NKJ64 using the HPLC methodology investigated. This study highlights the importance of HPLC purification and accurate measurement of specific activity while developing new radiosynthesis methodologies.

  18. CCR2-V64I polymorphism is associated with increased risk of cervical cancer but not with HPV infection or pre-cancerous lesions in African women

    Cervical cancer, caused by specific oncogenic types of human papillomavirus (HPV), is the second most common cancer in women worldwide. A large number of young sexually active women get infected by HPV but only a small fraction of them have persistent infection and develop cervical cancer pointing to co- factors including host genetics that might play a role in outcome of the HPV infection. This study investigated the role of CCR2-V64I polymorphism in cervical cancer, pre-cancers and HPV infection in South African women resident in Western Cape. CCR2-V64I polymorphism has been previously reported to influence the progression to cervical cancer in some populations and has also been associated with decreased progression from HIV infection to AIDS. Genotyping for CCR2-V64I was done by PCR-SSP in a case-control study of 446 women (106 black African and 340 mixed-ancestry) with histologically confirmed invasive cervical cancer and 1432 controls (322 black African and 1110 mixed-ancestry) group-matched (1:3) by age, ethnicity and domicile status. In the control women HPV was detected using the Digene Hybrid Capture II test and cervical disease was detected by cervical cytology. The CCR2-64I variant was significantly associated with cervical cancer when cases were compared to the control group (P = 0.001). Further analysis comparing selected groups within the controls showed that individuals with abnormal cytology and high grade squamous intraepitleial neoplasia (HSIL) did not have this association when compared to women with normal cytology. HPV infection also showed no association with CCR2-64I variant. Comparing SIL positive controls with the cases showed a significant association of CCR2-64I variant (P = 0.001) with cervical cancer. This is the first study of the role of CCR2-V64I polymorphism in cervical cancer in an African population. Our results show that CCR2-64I variant is associated with the risk of cervical cancer but does not affect the susceptibility to HPV

  20. A family of splice variants of CstF-64 expressed in vertebrate nervous systems

    2009-01-01

    Background Alternative splicing and polyadenylation are important mechanisms for creating the proteomic diversity necessary for the nervous system to fulfill its specialized functions. The contribution of alternative splicing to proteomic diversity in the nervous system has been well documented, whereas the role of alternative polyadenylation in this process is less well understood. Since the CstF-64 polyadenylation protein is known to be an important regulator of tissue-specific polyadenylation, we examined its expression in brain and other organs. Results We discovered several closely related splice variants of CstF-64 – collectively called βCstF-64 – that could potentially contribute to proteomic diversity in the nervous system. The βCstF-64 splice variants are found predominantly in the brains of several vertebrate species including mice and humans. The major βCstF-64 variant mRNA is generated by inclusion of two alternate exons (that we call exons 8.1 and 8.2) found between exons 8 and 9 of the CstF-64 gene, and contains an additional 147 nucleotides, encoding 49 additional amino acids. Some variants of βCstF-64 contain only the first alternate exon (exon 8.1) while other variants contain both alternate exons (8.1 and 8.2). In mice, the predominant form of βCstF-64 also contains a deletion of 78 nucleotides from exon 9, although that variant is not seen in any other species examined, including rats. Immunoblot and 2D-PAGE analyses of mouse nuclear extracts indicate that a protein corresponding to βCstF-64 is expressed in brain at approximately equal levels to CstF-64. Since βCstF-64 splice variant family members were found in the brains of all vertebrate species examined (including turtles and fish), this suggests that βCstF-64 has an evolutionarily conserved function in these animals. βCstF-64 was present in both pre- and post-natal mice and in different regions of the nervous system, suggesting an important role for βCstF-64 in neural gene

  6. A modeling framework for optimal long-term care insurance purchase decisions in retirement planning.

    Science.gov (United States)

    Gupta, Aparna; Li, Lepeng

    2004-05-01

    The level of need and costs of obtaining long-term care (LTC) during retired life require that planning for it is an integral part of retirement planning. In this paper, we divide retirement planning into two phases, pre-retirement and post-retirement. On the basis of four interrelated models for health evolution, wealth evolution, LTC insurance premium and coverage, and LTC cost structure, a framework for optimal LTC insurance purchase decisions in the pre-retirement phase is developed. Optimal decisions are obtained by developing a trade-off between post-retirement LTC costs and LTC insurance premiums and coverage. Two-way branching models are used to model stochastic health events and asset returns. The resulting optimization problem is formulated as a dynamic programming problem. We compare the optimal decision under two insurance purchase scenarios: one assumes that insurance is purchased for good and other assumes it may be purchased, relinquished and re-purchased. Sensitivity analysis is performed for the retirement age.

    As a first step in the evaluation of effective dose to patients in Computed Tomography (CT) examinations, the purpose of this work was the assessment of the dose delivered by a new multislice scanner of 64 channels (Philips Brilliance 64c). This was done through the measurement of the CT Dose Index free in air, normalized to the unit of applied charge, using different beam collimations and tube voltages. Fitting nonlinear models to the observed data, kilo voltage and over beaming (penumbra) parameters have been elicited. The kilo voltage exponent of the relationship between CT dose index and kilo voltage varies from 2,84 to 2,88. The obtained penumbra with was 2,04 nm. Finally, corrections factors that must be applied to the measured dose indexes as a function of the applied collimation have been established from the estimated analytical relationships. (Author)

We estimated the production yields of 64Cu and 67Cu by fast neutrons from \\text{natC(d,n) with 40 MeV 5 mA deuterons. We used the present result together with the evaluated cross section of Zn isotopes. The calculated 64Cu yield is 1.8 TBq (175 g 64Zn) for 12 h of irradiation; the yields of 67Cu by 67Zn(n,p)67Cu and 68Zn(n,x)67Cu were 249 GBq (184 g 67Zn) and 287 GBq (186 g 68Zn) at the end of 2 days of irradiation, respectively. From the results, we proposed a new route to produce 67Cu with very little radionuclide impurity via the 68Zn(n,x)67Cu reaction, and showed the 64Zn(n,p)64Cu reaction to be a promising route to produce 64Cu. Both 67Cu and 64Cu are noted to be produced using fast neutrons.

    Parental substance abuse confronts children with a variety of psychological, social, and behavioral problems. Children of substance abusing parents show higher levels of psychiatric disorders including anxiety and depression and exert lower levels of communication skills. Weak social skills in this group of adolescents put them at a higher risk for substance abuse. Many studies showed school based interventions such as life skill training can effective on future substance abusing in these high risk adolescences. The participants consisted of 57 middles schools girls, all living in rural areas and having both parents with substance dependency. The participants were randomly assigned to intervention (n=28) and control (n=29) groups. The data were collected before and six weeks after training in both group. The intervention group received eight sessions of group assertiveness training. Participants were compared in terms of changes in scores on the Oxford Happiness Questionnaire and the Gambrills-Richey Assertion Inventory. The total score for happiness change from 43.68 ±17.62 to 51.57 ±16.35 and assertiveness score changed from 110.33±16.05 to 90.40±12.84. There was a significant difference in pretest-posttest change in scores for intervention (7.89±4.13) and control (-2.51±2.64) groups; t (55) =2.15, p = 0.049. These results suggest that intervention really does have an effect on happiness and assertiveness. Determining the effectiveness of these school based interventions on other life aspects such as substance abuse calls for further study on these rural adolescent girls.

    Objective: To discuss the clinical value of coronary artery imaging using 64-slice spiral CT in patient with atrial fibrillation. Methods: The images of 31 patients with atrial fibrillation who underwent contrast-enhanced CT coronary angiography were evaluated. The presence of stenosis on each segment of coronary arteries was recorded and their degree of stenosis was measured using the vessel analysis software. Ten patients additionally underwent conventional coronary angiography. The results of conventional coronary angiography were compared with CT coronary angiography of the 10 patients. Results: Image reconstruction was based on absolute timing. The image quality of 364 coronary vessel segments on the images from 31 patients was evaluated and defined as excellent, fine, moderate or poor. The image quality was excellent, fine, moderate and poor in 85, 41, 5, and 8 vessel segments respectively in patient group with heart rate between 47 beat per minent (bpm) and 69 bpm; and in 63, 16, 13, and 15 vessel segments respectively in patent group with heart rate between 70 bpm and 79 bpm;and in 46, 25, 23, and 24 vessel segments in patient group with heart rate between 80 bpm and 105 bpm. There was significant difference among the three patient groups (H=22.08, P<0.01). Comparison was carried out between CT angiographic findings and conventional angiographic findings of the 125 segments of the coronary arteries in the 10 patients who underwent conventional coronary angiography. The sensitivity and specificity of CT angiography for diagnosing vessel with significant coronary stenosis (≥50% narrowing) was 85.0% (17/20) and 95.2% (100/105), respectively. Positive predictive value was 77.3% (17/22), and negative predictive value was 97.1% (100/103). Coronary CTA underestimated the lesions of 3 vessel segments and overestimated the lesions of 5 vessel segments. Conclusion: Coronary artery imaging with 64-slice row CT had clinical value for patients with atrial fibrillation

    We present UBV photometry of the highly reddened and poorly studied open cluster Berkeley 55, revealing an important population of B-type stars and several evolved stars of high luminosity. Intermediate-resolution far-red spectra of several candidate members confirm the presence of one F-type supergiant and six late supergiants or bright giants. The brightest blue stars are mid-B giants. Spectroscopic and photometric analyses indicate an age 50 {+-} 10 Myr. The cluster is located at a distance d Almost-Equal-To 4 kpc, consistent with other tracers of the Perseus Arm in this direction. Berkeley 55 is thus a moderately young open cluster with a sizable population of candidate red (super)giant members, which can provide valuable information about the evolution of intermediate-mass stars.

  1. The role of retiree health insurance in the early retirement of public sector employees.

    Science.gov (United States)

    Shoven, John B; Slavov, Sita Nataraj

    2014-12-01

    Most government employees have access to retiree health coverage, which provides them with group health coverage even if they retire before Medicare eligibility. We study the impact of retiree health coverage on the labor supply of public sector workers between the ages of 55 and 64. We find that retiree health coverage raises the probability of stopping full time work by 4.3 percentage points (around 38 percent) over two years among public sector workers aged 55-59, and by 6.7 percentage points (around 26 percent) over two years among public sector workers aged 60-64. In the younger age group, retiree health insurance mostly seems to facilitate transitions to part-time work rather than full retirement. However, in the older age group, it increases the probability of stopping work entirely by 4.3 percentage points (around 22 percent). Copyright © 2014 Elsevier B.V. All rights reserved.

    The steganography process combines mathematics and computer science. Steganography consists of a set of methods and techniques to embed the data into another media so that the contents are unreadable to anyone who does not have the authority to read these data. The main objective of the use of base64 method is to convert any file in order to achieve privacy. This paper discusses a steganography and encoding method using base64, which is a set of encoding schemes that convert the same binary data to the form of a series of ASCII code. Also, the EoF technique is used to embed encoding text performed by Base64. As an example, for the mechanisms a file is used to represent the texts, and by using the two methods together will increase the security level for protecting the data, this research aims to secure many types of files in a particular media with a good security and not to damage the stored files and coverage media that used.

    A prototype 64 pixel miniature camera has been designed and tested for the Simbol-X hard X-ray observatory to be flown on the joint CNES-ASI space mission in 2014. This device is called Caliste 64. It is a high performance spectro-imager with event time-tagging capability, able to detect photons between 2 keV and 250 keV. Caliste 64 is the assembly of a 1 or 2 min thick CdTe detector mounted on top of a readout module. CdTe detectors equipped with Aluminum Schottky barrier contacts are used because of their very low dark current and excellent spectroscopic performance. Front-end electronics is a stack of four IDeF-X V1.1 ASICs, arranged perpendicular to the detection plane, to read out each pixel independently. The whole camera fits in a 10 * 10 * 20 mm 3 volume and is juxtaposable on its four sides. This allows the device to be used as an elementary unit in a larger array of Caliste 64 cameras. Noise performance resulted in an ENC better than 60 electrons rms in average. The first prototype camera is tested at -10 degrees C with a bias of -400 V. The spectrum summed across the 64 pixels results in a resolution of 697 eV FWHM at 13.9 keV and 808 eV FWFM at 59.54 keV. (authors)

  5. Forced differentiation of CFU-s by iron-55 erythrocytocide

    Cascades of Auger electrons are emitted in the decay of 55 Fe and absorbed in tissue within a 1 μm radius. Cytocidal amounts of 55 Fe can therefore eliminate erythroid precursors with minimal damage to adjacent cells. Early events leave the granuloid series undisturbed but they are accompanied by a precipitous fall of pluripotent stem cells levels (CFU-s) in bone marrow, spleen, and blood. The pretreatment levels of CFU-s are not restored. Gradual decline of CFU-s is associated with intermittently increased turnover rate and reduced settings of cell production, yet unimpaired capacity for quick restoration of blood loss. The precipitous initial stem cell decrease is not caused by irradiation damage as shown in a separate experimental series which uses the frozen-storage cytocide technique. Only over several weeks could 55 Fe radiation accumulate to lethal levels in nondividing stem cells. This irradiation is attributed to incorporation of small amounts of 55 Fe into CFU-s from where it is slowly cleared. The stem cell loss immediately following 55 Fe injection is in our interpretation caused by rapid differentiation along the erythroid pathway in a response that involves all progenitor populations. Data are consistent with the hypothesis of limited cell renewal capacity which thereby gains further support

    Full Text Available Objective. To evaluate the expression of CD64 and CD163 on neutrophils and monocytes in SIRS with/without sepsis and to compare the diagnostic accuracy of CD64 and CD163 molecules expression determined as (1 mean fluorescence intensities (MFI of CD64 and CD163; and (2 the ratio (index of linearized MFI to the fluorescence signal of standardized beads. Patients and methods. Fifty-six critically ill neonates and children with systemic inflammatory response syndrome (SIRS and suspected sepsis, classified into two groups: SIRS with sepsis (n=29 and SIRS without sepsis (n=27. Results. CD64 and CD163 MFI measured on neutrophils and monocytes were elevated in patients with SIRS with sepsis. Diagnostic accuracy of indexes was equal to diagnostic accuracy of MFI for CD64 on neutrophils (0.833 versus 0.854 for day 0 and 0.975 versus 0.983 for day 1 and monocytes (0.811 versus 0.865 for day 0 and 0.825 versus 0.858 for day 1, and CD163 on neutrophils (0.595 versus 0.655 for day 0 and 0.677 versus 0.750 for day 1, but not for CD163 on monocytes. Conclusion. CD64 MFI, CD163 MFI, CD64 indexes for neutrophils and monocytes, and CD163 index for neutrophils can all be used for discrimination of SIRS and sepsis in critically ill neonates and children. CD64 index for neutrophils, however, is superior to all other markers.

    The purpose of this study was to examine and compare the melanoma targeting and imaging properties of (64)Cu-NOTA-GGNle-CycMSH(hex) {(64)Cu-1,4,7-triazacyclononane-1,4,7-triacetic acid-Gly-Gly-Nle-c[Asp-His-DPhe-Arg-Trp-Lys]-CONH2} and (64)Cu-DOTA-GGNle-CycMSH(hex) {(64)Cu-1,4,7,10-tetraazacyclononane-1,4,7,10-tetraacetic acid-GGNle-CycMSH(hex)}. Two lactam bridge-cyclized peptides, NOTA-GGNle-CycMSH(hex) and DOTA-GGNle-CycMSH(hex), were synthesized using fluorenylmethyloxy carbonyl (Fmoc) chemistry. The melanocortin-1 (MC1) receptor binding affinity of NOTA-GGNle-CycMSH(hex) was determined in B16/F1 melanoma cells and compared with DOTA-GGNle-CycMSH(hex). The melanoma targeting and imaging properties of (64)Cu-NOTA-GGNle-CycMSH(hex) and (64)Cu-DOTA-GGNle-CycMSH(hex) were determined in B16/F1 melanoma-bearing C57 mice. NOTA-GGNle-CycMSH(hex) and DOTA-GGNle-CycMSH(hex) displayed comparable MC1 receptor binding affinities (1.6 vs 2.1 nM). The substitution of DOTA with NOTA dramatically increased the melanoma uptake and decreased the renal and liver uptake of (64)Cu-NOTA-GGNle-CycMSH(hex). The tumor uptake of (64)Cu-NOTA-GGNle-CycMSH(hex) was between 12.39 ± 1.61 and 12.71 ± 2.68% ID/g at 0.5, 2, and 4 h postinjection. The accumulation of (64)Cu-NOTA-GGNle-CycMSH(hex) activity in normal organs was lower than 1.02% ID/g except for the kidneys 2, 4, and 24 h postinjection. The tumor/liver uptake ratios of (64)Cu-NOTA-GGNle-CycMSHhex were 17.96, 16.95, and 8.02, whereas the tumor/kidney uptake ratios of (64)Cu-NOTA-GGNle-CycMSH(hex) were 2.52, 3.60, and 5.74 at 2, 4, and 24 h postinjection, respectively. Greater than 91% of the injected radioactivity cleared through the urinary system by 2 h postinjection. The substitution of DOTA with NOTA resulted in a dramatic increase in melanoma uptake and decrease in renal and liver uptake of (64)Cu-NOTA-GGNle-CycMSH(hex) as compared to (64)Cu-DOTA-GGNle-CycMSH(hex).

  15. 64Cu-Labeled LyP-1-Dendrimer for PET-CT Imaging of Atherosclerotic Plaque

    Science.gov (United States)

    2015-01-01

    The ability to detect and quantify macrophage accumulation can provide important diagnostic and prognostic information for atherosclerotic plaque. We have previously shown that LyP-1, a cyclic 9-amino acid peptide, binds to p32 proteins on activated macrophages, facilitating the visualization of atherosclerotic plaque with PET. Yet, the in vivo plaque accumulation of monomeric [18F]FBA-LyP-1 was low (0.31 ± 0.05%ID/g). To increase the avidity of LyP-1 constructs to p32, we synthesized a dendritic form of LyP-1 on solid phase using lysine as the core structural element. Imaging probes (FAM or 6-BAT) were conjugated to a lysine or cysteine on the dendrimer for optical and PET studies. The N-terminus of the dendrimer was further modified with an aminooxy group in order to conjugate LyP-1 and ARAL peptides bearing a ketone. Oxime ligation of peptides to both dendrimers resulted in (LyP-1)4- and (ARAL)4-dendrimers with optical (FAM) and PET probes (6-BAT). For PET-CT studies, (LyP-1)4- and (ARAL)4-dendrimer-6-BAT were labeled with 64Cu (t1/2 = 12.7 h) and intravenously injected into the atherosclerotic (ApoE–/–) mice. After two hours of circulation, PET-CT coregistered images demonstrated greater uptake of the (LyP-1)4-dendrimer-64Cu than the (ARAL)4-dendrimer-64Cu in the aortic root and descending aorta. Ex vivo images and the biodistribution acquired at three hours after injection also demonstrated a significantly higher uptake of the (LyP-1)4-dendrimer-64Cu (1.1 ± 0.26%ID/g) than the (ARAL)4-dendrimer-64Cu (0.22 ± 0.05%ID/g) in the aorta. Similarly, subcutaneous injection of the LyP-1-dendrimeric carriers resulted in preferential accumulation in plaque-containing regions over 24 h. In the same model system, ex vivo fluorescence images within aortic plaque depict an increased accumulation and penetration of the (LyP-1)4-dendrimer-FAM as compared to the (ARAL)4-dendrimer-FAM. Taken together, the results suggest that the (LyP-1)4-dendrimer can be applied for in

    We occupy ourselves with preparation of 64 Cu using cyclotron IBA 18/9. 64 Cu is a starting product for production of radiopharmaceuticals for positron emission tomographic diagnostics and therapy and metrological characterization as well. The use of non-traditional PET radionuclides has been spread in the world recently. Due to the physical properties (T 1/2 =12.7 h, β- 37.1 %, β + 17.9 %), 64 Cu is suitable for therapy (β - ) and diagnosing as well (β+). 64 Cu is suitable radionuclide for labeling of radiopharmaceuticals on the basis of bis-thiosemicarbazone for study of hypoxic tumors. The number and orientation of articles and papers at conferences show a great demand for 64 Cu in the world. It is caused by specific physical properties and possibility of preparation in small biomedical cyclotrons as well. An electrolytic preparation of a target lies in a galvanostatic plating of 64 Ni on a gold target. The target is irradiated by a cyclotron IBA Cyclone 18/9. COSTIS station (Compact Solid Target Irradiation System) is installed at the end of external proton beam. 64 Cu is separated from the target material by ionex Bio-Rad AG1-X8 as [ 64 Cu]CuCl 2 . The target material is recycled by a simple method. A process of 64 Cu preparation is completely automated and runs in a separation module with Plc Simatin S-1200 developed by Biont a.s. The product was measured by an ionization chamber (Curiementor), HPGe detector and LSC method (TDCR). (author)

    We occupy ourselves with preparation of 64 Cu using cyclotron IBA 18/9. 64 Cu is a starting product for production of radiopharmaceuticals for positron emission tomographic diagnostics and therapy and metrological characterization as well. The use of non-traditional PET radionuclides has been spread in the world recently. Due to the physical properties (T 1/2 =12.7 h, β- 37.1 %, β + 17.9 %), 64 Cu is suitable for therapy (β - ) and diagnosing as well (β+). 64 Cu is suitable radionuclide for labeling of radiopharmaceuticals on the basis of bis-thiosemicarbazone for study of hypoxic tumors. The number and orientation of articles and papers at conferences show a great demand for 64 Cu in the world. It is caused by specific physical properties and possibility of preparation in small biomedical cyclotrons as well. An electrolytic preparation of a target lies in a galvanostatic plating of 64 Ni on a gold target. The target is irradiated by a cyclotron IBA Cyclone 18/9. COSTIS station (Compact Solid Target Irradiation System) is installed at the end of external proton beam. 64 Cu is separated from the target material by ionex Bio-Rad AG1-X8 as [ 64 Cu]CuCl 2 . The target material is recycled by a simple method. A process of 64 Cu preparation is completely automated and runs in a separation module with PLC SIMATIC S7-1200 developed by Biont a.s. The product was measured by an ionization chamber (Curiementor), HPGe detector and LSC method (TDCR). (author)

    Objective: Analyzing the left atrium and pulmonary vein morphologically by 64 multislice spiral CT (MSCT) scan to guide the catheter ablation of Atrial fibrillation. Methods: Two hundred and thirty-two patients (146 cases in atrial fibrillation group and 86 cases in control group) received 64 MSCT examination of the left atrium and pulmonary vein. The incidence of anatomical variation of pulmonary vein was compared between atrial fibrillation group and control group. For each group, the anatomical morphology of every pulmonary vein and the auricle of left atrium was analyzed, the diameter of the orifice of each pulmonary vein and the size of left atrium were measured. Results: Sixty-four MSCT of left atrium and pulmonary vein could demonstrate detailed connecting type between left atrium and pulmonary veins and the possible anatomical variation. Anatomical variation of pulmonary vein in this study accounted for 16.8% (39/232) of total sample. For both groups, orifices of pulmonary veins appeared oval and their superoinferior diameters were larger than their anteroposterior diameters. There was significant difference in the inner diameter of left atrium between atrial fibrillation group and control group [atrial fibrillation group: (39.47 ± 8.98) mm, control group: (36.94±5.49) mm, P=0.02], while there was no difference in the diameters of orifices of pulmonary veins between two groups [superoinferior diameters of pulmonary veins in atrial fibrillation group: left-up (18.15±1.35) mm, left-down (16.96±1.18) mm, right-up (17.50±1.12) mm, fight-down (17.65±0.94) mm, superoinferior diameters of pulmonary veins in control group: left-up (18.07±0.94) mm, left-down (17.50±0.57) mm, right-up (18.03±1.02) mm, fight-down (17.94±0.76) mm, the corresponding P>0.05, respectively, anteroposterior diameters of pulmonary veins in atrial fibrillation group: left-up (12.26±1.89) mm, left-down (11.96±0.61) mm, right-up (12.32± 1.08) mm, fight-down (12.39±0.95) mm

  4. Density functional investigation of the adsorption effects of PH3 and SH2 on the structure stability of the Au55 and Pt55 nanoclusters

    Although several studies have been reported for Pt55 and Au55 nanoclusters, our atomistic understanding of the interplay between the adsorbate-surface interactions and the mechanisms that lead to the formation of the distorted reduced core (DRC) structures, instead of the icosahedron (ICO) structure in gas phase, is still far from satisfactory. Here, we report a density functional theory (DFT) investigation of the role of the adsorption effects of PH3 (one lone pair of electrons) and SH2 (two lone pairs) on the relative stability of the Pt55 and Au55 nanoclusters. In gas phase, we found that the DRC structures with 7 and 9 atoms in the core region are about 5.34 eV (Pt55) and 2.20 eV (Au55) lower in energy than the ICO model with Ih symmetry and 13 atoms in the core region. However, the stability of the ICO structure increases by increasing the number of adsorbed molecules from 1 to 18, in which both DRC and ICO structures are nearly degenerate in energy at the limit of 18 ligands, which can be explained as follows. In gas phase, there is a strong compression of the cationic core region by the anionic surface atoms induced by the attractive Coulomb interactions (core+-surface-), and hence, the strain release is obtained by reducing the number of atoms in the cationic core region, which leads to the 55 atoms distorted reduced core structures. Thus, the Coulomb interactions between the core+ and surface- contribute to break the symmetry in the ICO55 structure. On the other hand, the addition of ligands on the anionic surface reduces the charge transfer between the core and surface, which contributes to decrease the Coulomb interactions and the strain on the core region of the ICO structure, and hence, it stabilizes a compact ICO structure. The same conclusion is obtained by adding van der Waals corrections to the plain DFT calculations. Similar results are obtained by the addition of steric effects, which are considered through the adsorption of triphenylphosphine

  5. Biological behaviour of some 67Ga and 64Cu chelates

    Chelates of 67 Ga and 64 Cu with iminodiacetic acid (IDA) and its two phenyl derivatives as well as with nitrilotriacetic acid (NTA) and benzylnitrilotriacetic acid (BNTA) were prepared. All the chelates were found to be negatively charged. A study of the biological distribution of these chelates in rats during time intervals of 3 to 180 min showed that the chelate of 67 Ga with IDA substituted at a phenyl by a hydrophobic substituent is excreted by the kidneys into the urine at a much higher rate than the IDA chelate of 67 Ga. The excretion of NTA and BNTA chelates of 67 Ga is the opposite. Blood clearance of 64 Cu chelates is more rapid than that of 67 Ga chelates. Chelates of 64 Cu accumulate in the liver and with the bile are slowly excreted into the intestines, urinary excretion is negligible. (author)

    Amnioinfusion is a relatively recent procedure introduced among fetal medicine techniques. Its applications focus on two different methods: transcervical and transabdominal. The first procedure usually is carried out during "intrapartum amnioinfusion" to prevent or treat fetal heart rate (FHR) decelerations related to oligohydramnios or to dilute thick meconium staining of the amniotic fluid. The latter method used during "antepartum amnioinfusion" is usually indicated for severe oligohydramnios in order to avoid the complications related such as pulmonary hypoplasia, deforming effects of oligohydramnios, variable FHR decelerations and intraventricular hemorrhages. Antepartum amnioinfusion, also used to improve ultrasound visualisation in presence of oligohydramnios, is less employed as compared to intrapartum amnioinfusion, therefore its risks are not well established. In order to study possible adverse effects on the mother or foetus, fifty five patients affected by oligohydramnios at 17th-34th week of gestational age were submitted to antepartum amnioinfusion (1-5 procedures) and were matched retrospectively with forty seven women with the same characteristics treated with the conservative and expectant management. The trend of pregnancy was the same for both groups in relation to maternal fever > 38 degrees (10.9% in the amnioinfused group vs 17.0% in control group ns), leukocyte count > 18,000/mm3 (25.5% vs 21.3%, ns), C-reactive protein > 10 ng/ml (10.9% vs 6.4%, ns). The latency period between admission and delivery was significantly longer in the amnioinfused group than in the control one [21 (range 1-98) vs 9 days (range 0-72); p amnioinfused group than in the control group (32.3% vs 66.6%; p amnioinfusion seems to increase the latency period between premature rupture of membranes and delivery, but it remains to clarify if this procedure is as much safe for the fetus as for the mother.

    2009-07-12

    In this project we proposed to establish feasibility of the development of targeted tracers for radionuclide imaging of epidermal growth factor receptors (EGFR) in cancer patients. The significance and impact of the proposed radiotracers are determined by the crucial role that EGFR plays in many cancers and by the rapid entrance of EGFR-inhibiting drugs into clinic. Clinical experience, however, revealed that only 10-25% of patients that are defined as EGFR-positive by immunohistochemical analysis respond to EGFR-directed therapeutics and there is poor correlation between EGFR immunohistochemistry and treatment. Therefore, for more efficacious use of EGFR-targeting therapeutics, there is a need for information about EGFR activity in patients. We hypothesized that radionuclide imaging of functionally active EGFR will provide such information and would allow for 1) rational patient stratification, 2) rapid monitoring of responses to therapy, and 3) development of personalized treatment regimens. We hypothesized that tracers based epidermal growth factor (EGF), a natural EGFR ligand, as a targeting vector would be particularly advantageous. First, only functionally active and therefore critical for disease progression EGFRs will bind and internalize an EGF-based tracer. Second, continuous internalization of EGF-based tracers by recyclable EGFR would lead to intracellular accumulation of radionuclide and improved signal-to-background ratio. Third, small size of EGF relative to antibodies would facilitate tumor penetration with vastly better non-specific soft tissue and blood clearance rates. Fourth, as a human protein, EGF is not expected to be immunogenic. Finally, at the beginning of this project, we have already engineered and expressed functionally active EGF with an N-terminal Cys-tag for site-specific conjugation of various payloads, including radionuclide chelators.

    A prototype 64 pixel miniature camera has been designed and tested for the Simbol-X hard X-ray observatory to be flown on the joint CNES-ASI space mission in 2014. This device is called Caliste 64. It is a high performance spectro-imager with event time-tagging capability, able to detect photons between 2 keV and 250 keV. Caliste 64 is the assembly of a 1 or 2 min thick CdTe detector mounted on top of a readout module. CdTe detectors equipped with Aluminum Schottky barrier contacts are used because of their very low dark current and excellent spectroscopic performance. Front-end electronics is a stack of four IDeF-X V1.1 ASICs, arranged perpendicular to the detection plane, to read out each pixel independently. The whole camera fits in a 10 * 10 * 20 mm{sup 3} volume and is juxtaposable on its four sides. This allows the device to be used as an elementary unit in a larger array of Caliste 64 cameras. Noise performance resulted in an ENC better than 60 electrons rms in average. The first prototype camera is tested at -10 degrees C with a bias of -400 V. The spectrum summed across the 64 pixels results in a resolution of 697 eV FWHM at 13.9 keV and 808 eV FWFM at 59.54 keV. (authors)

    Introduction: Cardiovascular disease is the leading cause of death in the United States. The identification of vulnerable plaque at risk of rupture has been a major focus of research. Hypoxia has been identified as a potential factor in the formation of vulnerable plaque, and it is clear that decreased oxygen plays a role in the development of plaque angiogenesis leading to plaque destabilization. The purpose of this study is to demonstrate the feasibility of copper-64 labeled diacetyl-bis (N 4 -methylthiosemicarbazone) ( 64 Cu-ATSM), a positron-emitting radiopharmaceutical taken up in low-oxygen-tension cells, for the identification of hypoxic and potentially unstable atherosclerotic plaque in a mouse model. Methods: 64 Cu-ATSM PET was performed in 21 atherosclerotic apolipoprotein E knockout (ApoE −/− ) mice, 6 of which were fed high-fat diet (HFD) while the others received standard-chow diet (SCD), and 13 control wild type mice fed SCD. 4 SCD ApoE −/− mice and 4 SCD wild type mice also underwent 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography (PET) imaging one day prior to 64 Cu-ATSM PET. Results: 64 Cu-ATSM uptake was increased in the aortic arch in SCD ApoE −/− mice (average aortic arch/muscle (A/M) standardized uptake value ratio 7.5–30 min post injection: (5.66 ± 0.23) compared to control mice (A/M SUV ratio 7.5–30 min post injection (3.87 ± 0.22), p < 0.0001). HFD ApoE −/− mice also showed similarly increased aortic arch uptake on PET imaging in comparison to control mice. Immunohistochemistry in both HFD and SCD ApoE −/− mice revealed noticeable hypoxia by pimonidazole stain in atherosclerosis which was co-localized to macrophage by CD68 staining. Autoradiography assessment demonstrated the presence of hypoxia by 64 Cu-ATSM uptake correlated with pimonidazole uptake within the ex vivo atherosclerotic aortic arch specimens. A significant increase in 18 F-FDG uptake in the SCD ApoE −/− mice in comparison to

  14. Frequencies of CCR5-D32, CCR2-64I and SDF1-3’A mutations in Human Immunodeficiency Virus (HIV seropositive subjects and seronegative individuals from the state of Pará in Brazilian Amazonia

    Full Text Available The distribution of genetic polymorphisms of chemokine receptors CCR5-delta32, CCR2-64I and chemokine (SDF1-3’A mutations were studied in 110 Human Immunodeficiency Virus type 1 (HIV-1 seropositive individuals (seropositive group and 139 seronegative individuals (seronegative group from the population of the northern Brazilian city of Belém which is the capital of the state of Pará in the Brazilian Amazon. The CCR5-delta32 mutation was found in the two groups at similar frequencies, i.e. 2.2% for the seronegative group and 2.7% for the seropositive group. The frequencies of the SDF1-3’A mutation were 21.0% for the seronegative group and 15.4% for the seropositive group, and the CCR2-64I allele was found at frequencies of 12.5% for the seronegative group and 5.4% for the seropositive group. Genotype distributions were consistent with Hardy-Weinberg expectations in both groups, suggesting that none of the three mutations has a detectable selective effect. Difference in the allelic and genotypic frequencies was statistically significant for the CCR2 locus, the frequency in the seronegative group being twice that found in the seropositive group. This finding may indicate a protective effect of the CCR2-64I mutation in relation to HIV transmission. However, considering that the CCR2-64I mutation has been more strongly associated with a decreased risk for progression for AIDS than to the resistance to the HIV infection, this could reflect an aspect of population structure or a Type I error.

  15. Photoinduced transport in an H64Q neuroglobin antidote for carbon monoxide poisoning

    2018-03-01

    Carbon monoxide (CO) is a leading cause of poisoning deaths worldwide, without available antidotal therapy. Recently, a potential treatment for CO poisoning was introduced, based on binding of CO by neuroglobin (Ngb) with a mutated distal histidine (H64Q). Here, we present an atomistic mechanism of CO trapping by H64Q Ngb revealed by nonadiabatic molecular dynamics. We focused on CO photodissociation and recombination of CO to wild type (WT) and H64Q Ngb. Our results demonstrate that the distribution of CO within the proteins differs substantially due to rearrangement of amino acids surrounding the distal heme pocket. This leads to the decrease of the distal pocket volume in H64Q Ngb in comparison to WT Ngb, trapping migrating CO molecules in the distal pocket. We show that the mutation implicates the shortening of the time scale of CO geminate recombination, making H64Q Ngb 2.7 times more frequent binder than WT Ngb.

    A decreased plasma high density lipoprotein (HDL) cholesterol level is a strong risk factor for coronary artery disease (CAD). Antioxidant activity of HDL mainly lies in the activity of paraoxonase (PON). This study aimed to investigate the relationships between PON1 L55M and Q192R polymorphisms, and the risks of CAD in patients with hyperlipidemia. From January 2014 to January 2016, 244 patients were divided into hyperlipidemia, hyperlipidemia + CAD, and control groups. The hyperlipidemia and hyperlipidemia + CAD groups were designated as the case group. Serum PON1 concentrations were measured using the enzyme-linked immunosorbent assay. After isolating genomic DNA, the PON1 L55M and Q192R genes were amplified by polymerase chain reaction and sequenced. In the case group, the genotypes LM and LL were detected significantly more often than in the control group, as were the alleles R (33.33%, 42.12%) and L (22.78%, 29.11%). The frequency of QR and RR genotypes was significantly higher in the hyperlipidemia + CAD group than in the hyperlipidemia group; the allele R in the hyperlipidemia + CAD group (42.77%) was more frequent than in the hyperlipidemia group (23.78%). The Q192R polymorphism was associated with low serum PON1 concentrations, and the lowest concentration was observed in the 192QR + 192RR genotype (P = 0.03). Logistic regression analysis showed a significant correlation between the 192R allele and smoking (P = 0.03), body mass index (P = 0.02), systolic blood pressure (P = 0.004), total cholesterol (P = 0.03), triglycerides (P = 0.01), HDL (P = 0.004), and low density lipoprotein (P = 0.02). The PON1 alleles 192R and 55L are associated with CAD, and the Q192R polymorphism may be a risk factor for CAD.

    The purpose of this study was to determine the safety, distribution, internal dosimetry, and initial human epidermal growth factor receptor 2 (HER2)-positive tumor images of (64)Cu-DOTA-trastuzumab in humans. PET was performed on 6 patients with primary or metastatic HER2-positive breast cancer at 1, 24, and 48 h after injection of approximately 130 MBq of the probe (64)Cu-DOTA-trastuzumab. Radioactivity data were collected from the blood, urine, and normal-tissue samples of these 6 patients, and the multiorgan biodistribution and internal dosimetry of the probe were evaluated. Safety data were collected for all the patients after the administration of (64)Cu-DOTA-trastuzumab and during the 1-wk follow-up period. According to our results, the best timing for the assessment of (64)Cu-DOTA-trastuzumab uptake by the tumor was 48 h after injection. Radiation exposure during (64)Cu-DOTA-trastuzumab PET was equivalent to that during conventional (18)F-FDG PET. The radioactivity in the blood was high, but uptake of (64)Cu-DOTA-trastuzumab in normal tissues was low. In 2 patients, (64)Cu-DOTA-trastuzumab PET showed brain metastases, indicative of blood-brain barrier disruptions. In 3 patients, (64)Cu-DOTA-trastuzumab PET imaging also revealed primary breast tumors at the lesion sites initially identified by CT. The findings of this study indicated that (64)Cu-DOTA-trastuzumab PET is feasible for the identification of HER2-positive lesions in patients with primary and metastatic breast cancer. The dosimetry and pharmacologic safety results were acceptable at the dose required for adequate PET imaging.

    Positron emission tomography offers advantages for radioimmunodiagnosis of cancer but requires radionuclides of appropriate half-life that have high specific activity and high radio-purity. This work was designed to develop a viable method to produce and purify 64Cu, which has high specific activity, for positron emission tomography. 64Cu was produced at the University of Missouri Research Reactor by the nuclear reaction, 64Zn(n,p)64Cu. Highly pure zinc metal (99.9999%) was irradiated in a specially designed boron nitrite lined container, which minimized thermal neutron reactions during irradiation. A new two-step procedure was developed to chemically separate the no-carrier-added 64Cu from the zinc metal target. 64Cu recovery for 24 runs averaged 0.393 (+/- 0.007) mCi per milligram of zinc irradiated. The boron-lined irradiation container reduced unwanted zinc radionuclides 14.3-fold. Zinc radionuclides and non-radioactive zinc were separated successfully from the 64Cu. The new separation technique was fast (2 hours total time) and highly efficient for removing the zinc. The zinc separation factor for this technique averaged 8.5 x 10(-8), indicating less than 0.0000085% of the zinc remained after separation. Thus far, the highest 64Cu specific activity at end of irradiation was 683 Ci/mg Cu, with an average of 512 Ci/mg Cu for the last six analyzed runs. The boron-lined irradiation container has sufficient capacity for 75-fold larger-sized zinc targets (up to 45 g). The new separation technique was excellent for separating 64Cu, which appears to be a radionuclide with great potential for positron emission tomography.

    Stroke is a leading cause of long-term disability and the fifth leading cause of death in Israel. Knowledge of stroke warning signs has been linked to early seeking of medical help. Little is known about knowledge of stroke warning signs in Israeli Jewish adults. Stroke knowledge was examined among Jewish Israeli adults. Using a structured questionnaire, registered nurses interviewed a convenience sample of the respondents, 18 years or older, with no stroke history. Stroke knowledge and demographics were examined by 3 age groups (64 years) in men and women. In total, 1137 Jewish Israelis were interviewed, 457 (40.2%) men and 680 women (59.8%); 493 (43.4%) were younger than 45 years, 541 (47.6%) were aged 45 to 64 years, and 102 (9%) were older than 64 years; 1 (0.1%) did not report age. On average, each interview lasted for 25 to 30 minutes. Participants younger than 45 years showed the lowest knowledge of stroke cause. Women younger than 45 years were less likely to identify at least 2 stroke warning signs. Participants younger than 45 years were less likely to identify at least 2 risk factors, compared with participants aged 45 to 64 years and older than 64 years. Women younger than 45 years were less likely to identify at least 2 stroke prevention strategies. Participants younger than 45 years showed the lowest levels of stroke knowledge. The highest stroke knowledge was found in the 45 to 64 years age group. Stroke knowledge among different age groups was similar in both genders. Educational campaigns aimed at increasing knowledge of stroke among the general population and targeting the younger population are recommended.

  5. On the Mechanism of Berberine-INF55 (5-Nitro-2-phenylindole) Hybrid Antibacterials.

    Berberine-INF55 hybrids are a promising class of antibacterials that combine berberine and the NorA multidrug resistance pump inhibitor INF55 (5-nitro-2-phenylindole) together in one molecule via a chemically stable linkage. Previous studies demonstrated the potential of these compounds for countering efflux-mediated antibacterial drug resistance but they didn't establish whether the compounds function as originally intended, i.e. with the berberine moiety providing antibacterial activity and the attached INF55 component independently blocking multidrug resistance pumps, thereby enhancing the activity of berberine by reducing its efflux. We hypothesised that if the proposed mechanism is correct, then hybrids carrying more potent INF55 pump inhibitor structures should show enhanced antibacterial effects relative to those bearing weaker inhibitors. Two INF55 analogues showing graded reductions in NorA inhibitory activity compared with INF55 were identified and their corresponding berberine-INF55 hybrids carrying equivalent INF55 inhibitor structures synthesised. Multiple assays comparing the antibacterial effects of the hybrids and their corresponding berberine-INF55 analogue combinations showed that the three hybrids all show very similar activities, leading us to conclude that the antibacterial mechanism(s) of berberine-INF55 hybrids is different from berberine-INF55 combinations.

    Purpose: To evaluate the variability of coronary calcium scores depending on the image reconstruction interval using a 64-slice CT scanner. Materials and Methods: 30 patients (18 male, 12 female; mean age 57 ± 9 yrs; mean heart rate 66 ± 10 bpm) underwent coronary calcium scoring using a 64-slice CT scanner (Somatom Sensation 64, Siemens Medical Solutions, Erlangen) and a standardized scanning protocol. Oral β-blockers were administered to 12 patients with a baseline heart rate > 70 bpm. Images were reconstructed in 10 % increments from 10 - 100 % of the RR interval. Two blinded experienced observers independently calculated Agatston (AS), calcium mass (MS) and volume scores (VS) for every reconstructed image series. The results were compared to similar studies for 16-slice CT scanners. Results: The mean values and mean coefficients of variation among all patients were as follows: AS, 397 ± 829, 109 % MS, 88 ± 225, 154 % VS, 335 ± 669, 100 %. Regarding the reconstruction intervals, the mean coefficients of variation were as follows: 107 % (AS), 97 % (VS), 116 % (MS). No specific image reconstruction interval with statistically significant lower variability for each score could be identified. High inter-observer agreement was achieved (K = 0.98). With statistical significance (p < 0.05) 10/30 patients (pts) were able to be allocated to more than one risk group (RG): 6 pts = 2 RG; 3 pts 3 RG; 1 pts = 4 RG. The scores for 5/30 patients were zero for at least one reconstruction interval, but further reconstructions revealed calcifications. The number of patients assignable to different risk groups was significantly lower compared to published data using a 16-slice scanner (p < 0.05). Conclusion: Coronary calcium scores determined using a 64-slice scanner display a wide range of variability depending on the image reconstruction interval as already described for 16-slice CT scanners. However, compared to previous studies, our data indicate that this vendor

    Full Text Available "nBackground: Multislice computed tomography (MSCT is a noninvasive method of detecting coronary artery disease (CAD. The purpose of the present study was to investigate the accuracy of 64-slice MSCT (64-MSCT in daily practice, without patient selection. "nMethods: Sixty-four consecutive suspected CAD patients underwent both 64-MSCT and quantitative coronary angiography (QCA. The CT system The mean time span between MSCT and QCA was 7.2±3.9 days. For the 64-MSCT, detection or exclusion of CAD, defined as one or more areas of >50% stenosis within major epicardial coronary arteries, the sensitivity, specificity, diagnostic accuracy, positive predictive value (PPV, and negative predictive value (NPV were evaluated both per patient and per segment. "nResults: Sixty-one of the 64 coronary CT angiograms (95% were of diagnostic image quality. QCA showed significant CAD in 64% (39/61 of the patients, with the other 36% (22/61 showing nonsignificant disease or no disease. Sensitivity, specificity, accuracy, PPV, and NPV of 64-MSCT per patient were 92%, 86%, 90%, 92% and 96%, respectively. By the per-segment analysis, 695 of 791 coronary artery segments were assessable (88%. Of these, 64-MSCT showed a sensitivity of 80%, specificity of 92%, accuracy of 90%, PPV of 65%, and NPV of 96%, respectively, in detecting CAD. "nConclusions: Both per patient and per segment analyses for coronary 64-MSCT showed a higher diagnostic accuracy than QCA. This suggests 64-MSCT should primarily be used for risk stratification on a per patient basis as a noninvasive gate-keeper diagnostic method.

    To study the sensitivity and specificity of CD64 in immunotyping of acute myeloid leukemia(AML). The bone marrow cells from 132 patients with AML were labelled with a series of antigens and were analyzed by flow cytometry. CD64 has high sensitivity in patients with acute myelomonocytic leukemia (M4) 96.4% and acute monocytic leukemia (MS) (96.4% and 100%, respectively). The expressions of CD64 was very low on patients with other kinds of AML(M0, M1, M2, M3, M6, M7). The specificity of CD64 in patients with M4 and M5 was 56.5%. The results suggest that the CD64 is helpful in the differential diagnosis of M4 and M5 in AML patients. (authors)

    The anti-tumor action of the complex of Bleomycin (BLM) with high specific-radioactivity 64 Cu on Ehrlich ascites tumour (EAT) was studied in vivo. The 64 Cu-BLM was administered into intraperitoneal cavity of mice from 1 to 4 days after inoculation of EAT cells. The effect of 64 Cu-BLM to suppress the tumour growth as demonstrated by prolonging life span was observed. The amounts of 64 Cu-BLM (800 μCi-8 mg/Kg) were administered at 4, 8 and 16 times separately. Then, the shorter the time interval and the less the amounts of drugs at a time, the higher the suppressing effect for the tumour growth was. It was confirmed that anti-tumour action of 64 Cu-BLM was in all the cases higher than that of BLM alone. (author)

    Although several studies have been reported for Pt 55 and Au 55 nanoclusters, our atomistic understanding of the interplay between the adsorbate-surface interactions and the mechanisms that lead to the formation of the distorted reduced core (DRC) structures, instead of the icosahedron (ICO) structure in gas phase, is still far from satisfactory. Here, we report a density functional theory (DFT) investigation of the role of the adsorption effects of PH 3 (one lone pair of electrons) and SH 2 (two lone pairs) on the relative stability of the Pt 55 and Au 55 nanoclusters. In gas phase, we found that the DRC structures with 7 and 9 atoms in the core region are about 5.34 eV (Pt 55 ) and 2.20 eV (Au 55 ) lower in energy than the ICO model with I h symmetry and 13 atoms in the core region. However, the stability of the ICO structure increases by increasing the number of adsorbed molecules from 1 to 18, in which both DRC and ICO structures are nearly degenerate in energy at the limit of 18 ligands, which can be explained as follows. In gas phase, there is a strong compression of the cationic core region by the anionic surface atoms induced by the attractive Coulomb interactions (core + -surface - ), and hence, the strain release is obtained by reducing the number of atoms in the cationic core region, which leads to the 55 atoms distorted reduced core structures. Thus, the Coulomb interactions between the core + and surface - contribute to break the symmetry in the ICO 55 structure. On the other hand, the addition of ligands on the anionic surface reduces the charge transfer between the core and surface, which contributes to decrease the Coulomb interactions and the strain on the core region of the ICO structure, and hence, it stabilizes a compact ICO structure. The same conclusion is obtained by adding van der Waals corrections to the plain DFT calculations. Similar results are obtained by the addition of steric effects, which are considered through the adsorption of

    Cannabinoid receptor 1 (CB1) is the best-characterized cannabinoid receptor, and CB1 antagonists are used in clinical trials to treat obesity. Because of the wide range of CB1 functions, the side effects of CB1 antagonists pose serious concerns. G-protein-coupled receptor 55 (GPR55) is an atypical cannabinoid receptor, and its pharmacology and functions are distinct from CB1. GPR55 regulates neuropathic pain, gut, bone, immune functions and motor coordination. GPR55 is expressed in various brain regions and peripheral tissues. However, the roles of GPR55 in energy and glucose homeostasis are unknown. Here we have investigated the roles of GPR55 in energy balance and insulin sensitivity using GPR55-null mice (GPR55(-/-)). Body composition of the mice was measured by EchoMRI. Food intake, feeding behavior, energy expenditure and physical activity of GPR55(-/-) mice were determined by indirect calorimetry. Muscle function was assessed by forced treadmill running test. Insulin sensitivity was evaluated by glucose and insulin tolerance tests. Adipose inflammation was assessed by flow cytometry analysis of adipose tissue macrophages. The expression of inflammatory markers in adipose tissues and orexigenic/anorexigenic peptides in the hypothalamus was also analyzed by real-time PCR. GPR55(-/-) mice had normal total energy intake and feeding pattern (i.e., no changes in meal size, meal number or feeding frequency). Intriguingly, whereas adult GPR55(-/-) mice only showed a modest increase in overall body weight, they exhibited significantly increased fat mass and insulin resistance. The spontaneous locomotor activity of GPR55(-/-) mice was dramatically decreased, whereas resting metabolic rate and non-shivering thermogenesis were unchanged. Moreover, GPR55(-/-) mice exhibited significantly decreased voluntary physical activity, showing reduced running distance on the running wheels, whereas muscle function appeared to be normal. GPR55 has an important role in energy

    The hydrogen storage alloys MmNi 3.55 Mn 0.4 Al 0.3 Co 0.75-x Fe x (x = 0.55 and 0.75) were used as negative electrodes in the Ni-MH accumulators. The chronopotentiommetry and the cyclic voltammetry were applied to characterize the electrochemical properties of these alloys. The obtained results showed that the substitution of the cobalt atoms by iron atoms has a good effect on the life cycle of the electrode. For the MmNi 3.55 Mn 0.4 Al 0.3 Co 0.2 Fe 0.55 compound, the discharge capacity reaches its maximum of 210 mAh/g after 12 cycles and then decreases to 190 mAh/g after 30 charge-discharge cycles. However, for the MmNi 3.55 Mn 0.4 Al 0.3 Fe 0.75 compound, the discharge capacity reaches its maximum of 200 mAh/g after 10 cycles and then decreases to 160 mAh/g after 30 cycles. The diffusion behavior of hydrogen in the negative electrodes made from these alloys was characterized by cyclic voltammetry after few activation cycles. The values of the hydrogen coefficient in MmNi 3.55 Mn 0.4 Al 0.3 Co 0.2 Fe 0.55 and MmNi 3.55 Mn 0.4 Al 0.3 Fe 0.75 are, respectively, equal to 2.96 x 10 -9 and 4.98 x 10 -10 cm 2 s -1 . However, the values of the charge transfer coefficients are, respectively, equal to 0.33 and 0.3. These results showed that the substitution of cobalt by iron decreases the reversibility and the kinetic of the electrochemical reaction in these alloys

    During the last 10 years, the Geograns Program within the NAUGRAN initiative of the University of Valencia is using trekking as a way to teach in the field Earth Science. This paper review the contribution of this program and show the results and future challenges. The life expectancy is growing all over the world. This is a clear trend in the Western societies where after two generations there is a large group of inhabitants that have a new life after retirement. The universities must understand that this new group of citizens need services that will allow them to know better the society. This is why the University of Valencia developed in the end of the 90's a program to teach to students older than 55. The program that allows to those students to attend lectures at the University is called NAUGRAN. This is a program for more than one thousand students that cover the needs of a group that is having more and more population over the age of 55, and with a life expectancy that surpass the 81 years in Spain. Teaching History, Arts, Sciences or Literature can be easily due for those 55-old students. However, teaching geosciences is being very difficult, as the students must visit the field and the laboratory. Within the GEOGRANS project, and during the last six years, Physical Geography was taught to students older than 55 in independent lecture rooms and field and laboratory classes. The main strategy was to show them the concepts and the ideas of the Physical Geography in the field. The excursions allow to shown the main features of the landscape (rivers, mountains, rocks…) and the impacts of the humankind on the changes of the nature to the students. The program is now 6 years old and it is being very successful with more than 200 hundreds participants and with excursion every two weeks. This paper will show the importance of teaching to students that arrive to the university after retirement. And that trekking is a successful strategy as the students realise

    Full Text Available The interactions that occur during HIV Pr55Gag oligomerization and genomic RNA packaging are essential elements that facilitate HIV assembly. However, mechanistic details of these interactions are not clearly defined. Here, we overcome previous limitations in producing large quantities of full-length recombinant Pr55Gag that is required for isothermal titration calorimetry (ITC studies, and we have revealed the thermodynamic properties of HIV assembly for the first time. Thermodynamic analysis showed that the binding between RNA and HIV Pr55Gag is an energetically favourable reaction (ΔG<0 that is further enhanced by the oligomerization of Pr55Gag. The change in enthalpy (ΔH widens sequentially from: (1 Pr55Gag-Psi RNA binding during HIV genome selection; to (2 Pr55Gag-Guanosine Uridine (GU-containing RNA binding in cytoplasm/plasma membrane; and then to (3 Pr55Gag-Adenosine(A-containing RNA binding in immature HIV. These data imply the stepwise increments of heat being released during HIV biogenesis may help to facilitate the process of viral assembly. By mimicking the interactions between A-containing RNA and oligomeric Pr55Gag in immature HIV, it was noted that a p6 domain truncated Pr50Gag Δp6 is less efficient than full-length Pr55Gag in this thermodynamic process. These data suggest a potential unknown role of p6 in Pr55Gag-Pr55Gag oligomerization and/or Pr55Gag-RNA interaction during HIV assembly. Our data provide direct evidence on how nucleic acid sequences and the oligomeric state of Pr55Gag regulate HIV assembly.

    Accurate measurements of the 64 Zn (n,2n) 64 Cu and 64 Zn (n,p) 63 Zn cross sections at 14.8 MeV have been made using a Texas Nuclear Neutron Generator and the activation technique. A NaI(T1) spectrometer (using two 6'' x 6'' NaI detectors/crystals) was used to measure the gamma radiation emitted in coincidence from the positron-emitting decay products. The measurements were made relative to 65 Cu (n,2n) /64/Cu and 63 Cu (n,2n) 62 Cu cross sections, which have similar half-lives, radiation emission, and were previously measured to high accuracy (2 percent). The value obtained for the (n,2n) measurement was 199 /+-/ 6 millibarns, and a value of 176 /+-/ 4.5 millibarns was obtained for the (n,p) measurement. In concert, a theoretical analysis of neutron induced reactions on /64/Zn was performed at Los Alamos National Laboratory using the Hauser-Feshbach statistical theory in the GNASH code over an energy range of 100 keV to 20 MeV. Calculations included width fluctuation corrections, direct reaction contributions, and preequilibrium corrections above 6 MeV. Neutron optical model potentials were determined for zinc. The theoretical values agree with the new 14.8 MeV measurements approximately within experimental error, with calculations of 201 millibarns for the (n,2n) cross section and 170 millibarns for the (n,p) cross section. Results from the analysis will be made available in National Evaluated Nuclear Data Format (ENDF/B) for fusion energy applications. 50 refs., 34 figs., 10 tabs

    Primary care providers in safety-net settings often do not have time to discuss advance care planning (ACP). Group visits (GV) may be an efficient means to provide ACP education. To assess the feasibility and impact of a video-based website to facilitate GVs to engage diverse adults in ACP. Feasibility pilot among patients who were ≥55 years of age from two primary care clinics in a Northern California safety-net setting. Participants attended two 90-minute GVs and viewed the five steps of the movie version of the PREPARE website ( www.prepareforyourcare.org ) concerning surrogates, values, and discussing wishes in video format. Two clinician facilitators were available to encourage participation. We assessed pre-to-post ACP knowledge, whether participants designated a surrogate or completed an advance directive (AD), and acceptability of GVs and PREPARE materials. We conducted two GVs with 22 participants. Mean age was 64 years (±7), 55% were women, 73% nonwhite, and 55% had limited literacy. Knowledge improved about surrogate designation (46% correct pre vs. 85% post, p = 0.01) and discussing decisions with others (59% vs. 90%, p = 0.01). Surrogate designation increased (48% vs. 85%, p = 0.01) and there was a trend toward AD completion (9% vs. 24%, p = 0.21). Participants rated the GVs and PREPARE materials a mean of 8 (±3.1) on a 10-point acceptability scale. Using the PREPARE movie to facilitate ACP GVs for diverse adults in safety net, primary care settings is feasible and shows potential for increasing ACP engagement.

    As a first step in the evaluation of effective dose to patients in Computed Tomography (CT) examinations, the purpose of this work was the assessment of the dose delivered by a new multislice scanner of 64 channels (Philips Brilliance 64c). This was done through the measurement of the CT Dose Index free in air, normalized to the unit of applied charge, using different beam collimations and tube voltages. Fitting nonlinear models to the observed data, kilo voltage and over beaming (penumbra) parameters have been elicited. The kilo voltage exponent of the relationship between CT dose index and kilo voltage varies from 2,84 to 2,88. The obtained penumbra with was 2,04 nm. Finally, corrections factors that must be applied to the measured dose indexes as a function of the applied collimation have been established from the estimated analytical relationships. (Author)

    In this work, a series of batch experiments were carried out to investigate the effect of various environmental factors such as contact time, pH, ionic strength, coexisting electrolyte ions, humic substances and temperature on the sorption behavior of illite towards 64 Cu(II). The results indicated that 64 Cu(II) sorption on illite achieved equilibrium quickly. The pH- and ionic strength-dependent sorption suggested that 64 Cu(II) sorption on illite was dominated by ion exchange or outer-sphere surface complexation at pH 7. A positive effect of humic substances on 64 Cu(II) sorption was found at pH 6.5. The Langmuir and Freundlich models were used to simulate the sorption isotherms of 64 Cu(II) at three different temperatures of 293, 313, and 333 K. The thermodynamic parameters (ΔH 0 , ΔS 0 , and ΔG 0 ) of 64 Cu(II) sorption on illite were calculated from the temperature dependent sorption isotherms, and the results indicated that the sorption of 64 Cu(II) on illite was endothermic and spontaneous. From the experimental results, it is possible to conclude that illite has good potentialities for cost-effective treatments of 64 Cu(II)-contaminated wastewaters. (author)

  5. Bombyx mori nucleopolyhedrovirus (BmNPV) Bm64 is required for BV production and per os infection.

    Bombyx mori nucleopolyhedrovirus (BmNPV) orf64 (Bm64, a homologue of ac78) is a core baculovirus gene. Recently, Li et al. reported that Ac78 was not essential for budded viruses (BVs) production and occlusion-derived viruses (ODVs) formation (Virus Res 191:70-82, 2014). Conversely, Tao et al. demonstrated that Ac78 was localized to the BV and ODV envelopes and was required for BV production and ODV formation (J Virol 87:8441-50, 2013). In this study, the function of Bm64 was characterized to determine the role of Bm64 in the BmNPV infection cycle. The temporal expression of Bm64 was examined using total RNA extracted from BmNPV-infected BmN cells at different time points by reverse-transcription PCR (RT-PCR) and 5' RACE analysis. To determine the functions of Bm64 in viral replication and the viral phenotype throughout the viral life cycle, a deletion virus (vBm(64KO)) was generated via homologous recombination in Escherichia coli. Viral replication and BV production were determined by real-time PCR. Electron microscopy was used to detect virion morphogenesis. The subcellular localization of Bm64 was determined by microscopy, and per os infectivity was used to determine its role in the baculovirus oral infection cycle. Viral plaque and titer assay results showed that a few infectious BVs were produced by vBm(64KO), suggesting that deletion of Bm64 affected BV production. Viral DNA replication was detected and polyhedra were observed in vBm(64KO)-transfected cells. Microscopy analysis revealed that Bm64 was predominantly localized to the ring zone of the nuclei during the infection cycle. Electron microscopy showed that Bm64 was not essential for the formation of ODVs or the subsequent occlusion of ODV into polyhedra. The per os infectivity results showed that the polyhedra of vBm(64KO) were unable to infect silkworm larvae. In conclusion, our results suggest that Bm64 plays an important role in BV production and per os infection, but is not required for viral DNA

    Full Text Available Central nervous system (CNS tuberculosis is a serious clinical problem, the treatment of which is sometimes hampered by delayed diagnosis. Clearly, prompt laboratory diagnosis is of vital importance as the spectrum of disease is wideand abnormalities of the cerebrospinal fluid (CSF are incredibly variable. Since delayed hypersensitivity is the underlying immune response, bacterial load is very low. The conventional bacteriological methods rarely detect Mycobacterium tuberculosis in CSF and are of limited use in diagnosis of tuberculous meningitis (TBM. This double blind study was, therefore, directed to the molecular analysis of CNS tuberculosis by an in-house-developed PCR targeted for amplification of a 240bp nucleotidesequence coding for MPB64 protein specific for Mycobacterium tuberculosis. Based on the clinical criteria, 47 patients with CNS tuberculosis and a control group of 10 patients having non-tubercular lesions of the CNS were included in the study. Analyses were done in three groups; one group consisting of 27 patients of TBM, a second group of 20 patients with intracranial tuberculomas and a third group of 10 patients having non-tubercular lesions of the CNS acted as control. There were no false positive results by PCR and the specificity worked out to be 100%. In the three study groups, routine CSF analysis (cells and chemistry, CSF for AFB smear and culture were negative in all cases. PCR was positive for 21/27 patients (77.7% sensitivity of the first group of TBM patients, 6/20 patients (30% sensitivity of the second group with intracranial tuberculomas were positive by PCR and none was PCR-positive (100% specificity in the third group. Thus, PCR was found to be more sensitive than any other conventional method in the diagnosis of clinically suspected tubercular meningitis.A tuberculose do sistema nervoso central (CNS é um problema clínico sério, cujo tratamento é dificultado pelo diagnóstico tardio.

    Introduction: {sup 123}I-NKJ64, a reboxetine analogue, is currently under development as a potential novel single photon emission computed tomography radiotracer for imaging the noradrenaline transporter in brain. This study describes the development of the radiosynthesis of {sup 123}I-NKJ64, highlighting the advantages and disadvantages, pitfalls and solutions encountered while developing the final radiolabelling methodology. Methods: The synthesis of {sup 123}I-NKJ64 was evaluated using an electrophilic iododestannylation method, where a Boc-protected trimethylstannyl precursor was radioiodinated using peracetic acid as an oxidant and deprotection was investigated using either trifluoroacetic acid (TFA) or 2 M hydrochloric acid (HCl). Results: Radioiodination of the Boc-protected trimethylstannyl precursor was achieved with an incorporation yield of 92{+-}6%. Deprotection with 2 M HCl produced {sup 123}I-NKJ64 with the highest radiochemical yield of 98.05{+-}1.63% compared with 83.95{+-}13.24% with TFA. However, the specific activity of the obtained {sup 123}I-NKJ64 was lower when measured after using 2 M HCl (0.15{+-}0.23 Ci/{mu}mol) as the deprotecting agent in comparison to TFA (1.76{+-}0.60 Ci/{mu}mol). Further investigation of the 2 M HCl methodology found a by-product, identified as the deprotected proto-destannylated precursor, which co-eluted with {sup 123}I-NKJ64 during the high-performance liquid chromatography (HPLC) purification. Conclusions: The radiosynthesis of {sup 123}I-NKJ64 was achieved with good isolated radiochemical yield of 68% and a high specific activity of 1.8 Ci/{mu}mol. TFA was found to be the most suitable deprotecting agent, since 2 M HCl generated a by-product that could not be fully separated from {sup 123}I-NKJ64 using the HPLC methodology investigated. This study highlights the importance of HPLC purification and accurate measurement of specific activity while developing new radiosynthesis methodologies.

    Molecular imaging of programmed cell death (apoptosis) in vivo is an innovative strategy for early assessment of treatment response and treatment efficacy in cancer patients. Externalization of phosphatidylserine (PS) to the cell membrane surface of dying cells makes this phospholipid an attractive molecular target for the development of apoptosis imaging probes. In this study, we have radiolabeled PS-binding 14-mer peptide FNFRLKAGAKIRFG (PSBP-6) with positron-emitter copper-64 ( 64 Cu) for PET imaging of apoptosis. Peptide PSBP-6 was conjugated with radiometal chelator 1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA) through an aminovaleric acid (Ava) linker for subsequent radiolabeling with 64 Cu to prepare radiotracer 64 Cu-NOTA-Ava-PSBP-6. PS-binding potencies of PSBP-6, NOTA-Ava-PSBP-6, and nat Cu-NOTA-Ava-PSBP-6 were determined in a competitive radiometric PS-binding assay. Radiotracer 64 Cu-NOTA-Ava-PSBP-6 was studied in camptothecin-induced apoptotic EL4 mouse lymphoma cells and in a murine EL4 tumor model of apoptosis using dynamic PET imaging. Peptide PSBP-6 was also conjugated via an Ava linker with fluorescein isothiocyanate (FITC). FITC-Ava-PSBP-6 was evaluated in flow cytometry and fluorescence confocal microscopy experiments. Radiopeptide 64 Cu-NOTA-Ava-PSBP-6 was synthesized in high radiochemical yields of >95%. The IC 50 values for PS-binding potency of PSBP-6, NOTA-Ava-PSBP-6, and nat Cu-NOTA-PSBP-6 were 600 μM, 30 μM, and 23 μM, respectively. A competitive radiometric cell binding assay confirmed binding of 64 Cu-NOTA-Ava-PSBP-6 to camptothecin-induced apoptotic EL4 cells in a Ca 2+ -independent manner. PET imaging studies demonstrated significantly higher uptake of 64 Cu-NOTA-Ava-PSBP-6 in apoptotic EL4 tumors (SUV 5min 0.95 ± 0.04) compared to control tumors (SUV 5min 0.74 ± 0.03). Flow cytometry studies showed significantly higher binding of FITC-Ava-PSBP-6 to EL4 cells treated with camptothecin compared to untreated cells

    2018-02-01

    Full Text Available Copper(II ion (Cu2+ is the essential element for numerous pathophysiological processes in vivo. Copper transporter 1 (CTR1 is mainly responsible for maintaining Cu2+ accumulation in cells, which has been found to be over-expressed in inflammatory tissues. Therefore, we explored the potential application of 64CuCl2 for PET imaging of inflammation through targeting CTR1. The animal models of H2O2 induced muscle inflammation and lipopolysaccaharide induced lung inflammation were successfully established, then imaged by small animal PET (PET/CT post-injection of 64CuCl2, and PET images were quantitatively analyzed. H&E and immunohistochemical (IHC staining and western blot experiments were performed for evaluating CTR1 levels in the inflammatory and control tissues. Both inflammatory muscle and lungs can be clearly imaged by PET. PET image quantitative analysis revealed that the inflammatory muscle and lungs showed significantly higher 64Cu accumulation than the controls, respectively (p < 0.05. Furthermore, IHC staining and western blot analysis demonstrated that compared with the controls, CTR1 expression was increased in both the inflammatory muscle and lungs, which was consistent with the levels of 64Cu2+ accumulation in these tissues. 64CuCl2 can be used as a novel, simple, and highly promising PET tracer for CTR1 targeted imaging of inflammation.

    The first implementation of the IA-64 architecture achieves high performance by using a highly parallel execution core, while maintaining binary compatibility with the IA-32 instruction set. Explicitly parallel instruction computing (EPIC) design maximizes performance through hardware and software synergy. The processor contains 25.4 million transistors and operates at 800 MHz. The chip is fabricated in a 0.18- mu m CMOS process with six metal layers and packaged in a 1012-pad organic land grid array using C4 (flip chip) assembly technology. A core speed back-side bus connects the processor to a 4-MB L3 cache. (6 refs).

  16. Forced differentiation of CFU-S by iron-55 erythrocytocide

    Cascades of Auger electrons are emitted in the decay of 55 Fe and absorbed in tissue within a 1μm radius. Cytocidal amounts of 55 Fe can therefore eliminate erythroid precursors with minimal damage to adjacent cells. A single intravenous injection leads to continued erythrocytocide in mice because the isotope is reutilized and has a 2.7 year half-life. The cytocide evokes an early compensatory response from morphologically unrecognizable precursors which differentiate into pronormoblasts. These early events leave the granuloid series undisturbed but they are accompanied by a precipitous fall in pluripotent stem cell (CFU-S) numbers in bone marrow, spleen, and blood. The pretreatment levels of CFU-S are not restored. Gradual decline of CFU-S is associated with intermittently increased turnover rates and reduced settings of cell production, yet the capacity for quick restoration of blood loss is unimpaired. The precipitous initial stem cell decrease is not caused by irradiation damage, as shown in a separate experimental series that used the frozen-storage cytocide technique. Only over several weeks could 55 Fe radiation accumulate to lethal levels in nondividing stem cells. This irradiation is attributed to incorporation of small amounts of 55 Fe into CFU-S, from where it is slowly cleared. The stem cell loss immediately following 55 Fe injection is in our interpretation caused by rapid differentiation along the erythroid pathway in a response that involves all progenitor populations. Data are consistent with the hypothesis of limited cell renewal capacity which thereby gains further support. (orig.) [de

    A classic experiment by G.D. Scott Nature 188, 908, 1960) showed that pouring balls into a rigid container filled the volume to an upper limit of 64% of the container volume, which is well below the 74% volume fraction filled by spheres in a hexagonal close packed (HCP) or face center cubic (FCC) lattice. Subsequent experiments have confirmed a ``random closed packed'' (RCP) fraction of about 64%. However, the physics of the RCP limit has remained a mystery. Our experiment on a cubical box filled with 49400 weakly sheared glass spheres reveals a first order phase transition from a disordered to an ordered state at a volume fraction of 64.5%. The ordered state consists of crystallites of mixed FCC and HCP symmetry that coexist with the amorphous bulk. The transition is initiated by homogeneous nucleation: in the shearing process small crystallites with about ten or fewer spheres dissolve, while larger crystallites grow.

    Introduction: Bone marrow is the soft tissue compartment inside the bones made up of hematopoietic cells, adipocytes, stromal cells, phagocytic cells, stem cells, and sinusoids. While [ 18 F]-FLT has been utilized to image proliferative marrow, to date, there are no reports of particle based positron emission tomography (PET) imaging agents for imaging bone marrow. We have developed copper-64 labeled liposomal formulation that selectively targets bone marrow and therefore serves as an efficient PET probe for imaging bone marrow. Methods: Optimized liposomal formulations were prepared with succinyl PE, DSPC, cholesterol, and mPEG-DSPE (69:39:1:10:0.1) with diameters of 90 and 140 nm, and were doped with DOTA-Bn-DSPE for stable 64 Cu incorporation into liposomes. Results: PET imaging and biodistribution studies with 64 Cu-labeled liposomes indicate that accumulation in bone marrow was as high as 15.18 ± 3.69%ID/g for 90 nm liposomes and 7.01 ± 0.92%ID/g for 140 nm liposomes at 24 h post-administration. In vivo biodistribution studies in tumor-bearing mice indicate that the uptake of 90 nm particles is approximately 0.89 ± 0.48%ID/g in tumor and 14.22 ± 8.07%ID/g in bone marrow, but respective values for Doxil® like liposomes are 0.83 ± 0.49%ID/g and 2.23 ± 1.00%ID/g. Conclusion: Our results indicate that our novel PET labeled liposomes target bone marrow with very high efficiency and therefore can function as efficient bone marrow imaging agents.

    2004-05-05

    A two-stage 68 degrees C/55 degrees C anaerobic degradation process for treatment of cattle manure was studied. In batch experiments, an increase of the specific methane yield, ranging from 24% to 56%, was obtained when cattle manure and its fractions (fibers and liquid) were pretreated at 68 degrees C for periods of 36, 108, and 168 h, and subsequently digested at 55 degrees C. In a lab-scale experiment, the performance of a two-stage reactor system, consisting of a digester operating at 68 degrees C with a hydraulic retention time (HRT) of 3 days, connected to a 55 degrees C reactor with 12-day HRT, was compared with a conventional single-stage reactor running at 55 degrees C with 15-days HRT. When an organic loading of 3 g volatile solids (VS) per liter per day was applied, the two-stage setup had a 6% to 8% higher specific methane yield and a 9% more effective VS-removal than the conventional single-stage reactor. The 68 degrees C reactor generated 7% to 9% of the total amount of methane of the two-stage system and maintained a volatile fatty acids (VFA) concentration of 4.0 to 4.4 g acetate per liter. Population size and activity of aceticlastic methanogens, syntrophic bacteria, and hydrolytic/fermentative bacteria were significantly lower in the 68 degrees C reactor than in the 55 degrees C reactors. The density levels of methanogens utilizing H2/CO2 or formate were, however, in the same range for all reactors, although the degradation of these substrates was significantly lower in the 68 degrees C reactor than in the 55 degrees C reactors. Temporal temperature gradient electrophoresis profiles (TTGE) of the 68 degrees C reactor demonstrated a stable bacterial community along with a less divergent community of archaeal species.

    Full Text Available Imaging using affibody molecules enables discrimination between breast cancer metastases with high and low expression of HER2, making appropriate therapy selection possible. This study aimed to evaluate if the longer half-life of 64Cu (T1/2 = 12.7 h would make 64Cu a superior nuclide compared to 68Ga for PET imaging of HER2 expression using affibody molecules. The synthetic ZHER2:S1 affibody molecule was conjugated with the chelators NOTA or NODAGA and labeled with 64Cu. The tumor-targeting properties of 64Cu-NOTA-ZHER2:S1 and 64Cu-NODAGA-ZHER2:S1 were evaluated and compared with the targeting properties of 68Ga-NODAGA-ZHER2:S1 in mice. Both 64Cu-NOTA-ZHER2:S1 and 64Cu-NODAGA-ZHER2:S1 demonstrated specific targeting of HER2-expressing xenografts. At 2 h after injection of 64Cu-NOTA-ZHER2:S1, 64Cu-NODAGA-ZHER2:S1, and 68Ga-NODAGA-ZHER2:S1, tumor uptakes did not differ significantly. Renal uptake of 64Cu-labeled conjugates was dramatically reduced at 6 and 24 h after injection. Notably, radioactivity uptake concomitantly increased in blood, lung, liver, spleen, and intestines, which resulted in decreased tumor-to-organ ratios compared to 2 h postinjection. Organ uptake was lower for 64Cu-NODAGA-ZHER2:S1. The most probable explanation for this biodistribution pattern was the release and redistribution of renal radiometabolites. In conclusion, monoamide derivatives of NOTA and NODAGA may be suboptimal chelators for radiocopper labeling of anti-HER2 affibody molecules and, possibly, other scaffold proteins with high renal uptake.

    The reaction 63 Cu(p,γ) 64 Zn has been studied in the proton energy range 1650-2750 keV using the Van de Graaff accelerator at B.A.R.C., Trombay. About 100 resonances were observed in the excitation function out of which the prominent ones at Esub(p)=1731, 1882, 2036, 2099, 2312, 2352, 2421 and 2479 keV have been identified as analogues of the ground and low-lying excited states of 64 Cu. The overall energy resolution was 2.5 keV. The Coulomb displacement energy for the isobaric pair 64 Cu- 64 Zn has been deduced to be 99.63 +- MeV. The spectra of γ-rays and their angular distributions have been obtained at resonances corresponding to the analogue of the ground and first four excited states of 64 Cu. The resonance strengths and the branching ratios for the γ-decay of the resonances has been presented. The M1 width of the γ-decay from resonance at 1751 keV to the ground state of 64 Zn, (0.20 +- 0.04)eV, is in excellent agreement with the value 0.19 eV deduced from the log ft value of 5.3 of the β decay of the parent analogue

    In order to help the gauge reduction of wheels and chassis parts of automobiles, a formable and weldable hot rolled steel of 550 MPa grade, named FDP-55, has been developed. FDP-55 is an 0.14% C, 0.1% Si, 1.1% Mn and Nb free Alkilled steel obtained by controlled-cooling to a low coiling temperature on a runout table, and it is featured by ferrite-degenerated pearlite microstructure. Results of co-operative works with automotive makers showed that FDP-55 was successful in the application to wheels and chassis parts attaining the large weight reduction. This paper reports the metallurgical features and characteristics of the steel

    64 Cu-DOTA-AE105 is a novel positron emission tomography (PET) tracer specific to the human urokinase-type plasminogen activator receptor (uPAR). In preparation of using this tracer in humans, as a new promising method to distinguish between indolent and aggressive cancers, we have performed PET studies in mice to evaluate the in vivo biodistribution and estimate human dosimetry of 64 Cu-DOTA-AE105. Methods: Five mice received iv tail injection of 64 Cu-DOTA-AE105 and were PET/CT scanned 1, 4.5 and 22 h post injection. Volume-of-interest (VOI) were manually drawn on the following organs: heart, lung, liver, kidney, spleen, intestine, muscle, bone and bladder. The activity concentrations in the mentioned organs [%ID/g] were used for the dosimetry calculation. The %ID/g of each organ at 1, 4.5 and 22 h was scaled to human value based on a difference between organ and body weights. The scaled values were then exported to OLINDA software for computation of the human absorbed doses. The residence times as well as effective dose equivalent for male and female could be obtained for each organ. To validate this approach, of human projection using mouse data, five mice received iv tail injection of another 64 Cu-DOTA peptide-based tracer, 64 Cu-DOTA-TATE, and underwent same procedure as just described. The human dosimetry estimates were then compared with observed human dosimetry estimate recently found in a first-in-man study using 64 Cu-DOTA-TATE. Results: Human estimates of 64 Cu-DOTA-AE105 revealed the heart wall to receive the highest dose (0.0918 mSv/MBq) followed by the liver (0.0815 mSv/MBq), All other organs/tissue were estimated to receive doses in the range of 0.02–0.04 mSv/MBq. The mean effective whole-body dose of 64 Cu-DOTA-AE105 was estimated to be 0.0317 mSv/MBq. Relatively good correlation between human predicted and observed dosimetry estimates for 64 Cu-DOTA-TATE was found. Importantly, the effective whole body dose was predicted with very high
