Many families worldwide have at least one member with a behavioral or mental disorder, and yet the majority of the public fails to correctly recognize symptoms of mental illness. Previous research has found that Mental Health Literacy (MHL)-the knowledge and positive beliefs about mental disorders-tends to be higher in European and North American cultures, compared to Asian and African cultures. Nonetheless quantitative research examining the variables that explain this cultural difference remains limited. The purpose of our study was fourfold: (a) to validate measures of MHL cross-culturally, (b) to examine the MHL model quantitatively, (c) to investigate cultural differences in the MHL model, and (d) to examine collectivism as a predictor of MHL. We validated measures of MHL in European American and Indian samples. The results lend strong quantitative support to the MHL model. Recognition of symptoms of mental illness was a central variable: greater recognition predicted greater endorsement of social causes of mental illness and endorsement of professional help-seeking as well as lesser endorsement of lay help-seeking. The MHL model also showed an overwhelming cultural difference; namely, lay help-seeking beliefs played a central role in the Indian sample, and a negligible role in the European American sample. Further, collectivism was positively associated with causal beliefs of mental illness in the European American sample, and with lay help-seeking beliefs in the Indian sample. These findings demonstrate the importance of understanding cultural differences in beliefs about mental illness, particularly in relation to help-seeking beliefs.

2017-01-01

Millions of children have a parent with a mental illness (COPMI). These children are at higher risk of acquiring behavioural, developmental and emotional difficulties. Most children, including COPMI, have low levels of mental health literacy (MHL), meaning they do not have accurate, non-stigmatized information. There is limited knowledge about what kind of MHL content should be delivered to children. The aim of this exploratory study is to identify the knowledge content needed for general population children and COPMI to increase their MHL. A second aim is to explore content for emerging children’s MHL scales. Researchers created and analyzed a literature review database. Thematic analysis yielded five main mental health knowledge themes for children: (1) attaining an overview of mental illness and recovery; (2) reducing mental health stigma; (3) building developmental resiliencies; (4) increasing help-seeking capacities; and (5) identifying risk factors for mental illness. COPMI appeared to need the same kind of MHL knowledge content, but with extra family-contextual content such as dealing with stigma experiences, managing stress, and communicating about parental mental illness. There is a need for MHL programs, validated scales, and research on what works for prevention and early intervention with COPMI children. PMID:29072587

Mental health literacy (MHL) is foundational for mental health promotion, prevention, stigma reduction, and care; School supported information pertaining to MHL in sub-Saharan Africa is extremely limited, including in Tanzania. Successful application of a school MHL curriculum resource may be an effective way to increase teacher MHL and therefore help to improve mental health outcomes for students. Secondary school teachers in Tanzania were trained on the African Guide (AG) a school MHL curriculum resource culturally adapted from a Canadian MHL resource (The Guide) for use in Africa. Teacher training workshops on the classroom application of the AG were used to evaluate its impact on mental health literacy in a sample of Tanzanian Secondary school teachers. Pre-post training assessment of participant knowledge and attitudes was conducted. Help-seeking efficacy for teachers themselves and their interventions for students, friends, family members and peers were determined. Paired t test (n = 37) results demonstrate highly significant improvements in teacher's overall knowledge (p Teachers' stigma against mental illness decreased significantly following the training (p teacher's overall knowledge (p Teachers also reported high rates (greater than ¾ of the sample) of positive help-seeking efficacy for themselves as well as for their students, friends, family members and peers. As a result of the training, the number of students teachers identified for potential mental health care totaled over 200. These positive results, when taken together with other research, suggest that the use of a classroom-based resource (the AG) that integrates MHL into existing school curriculum through training teachers may be an effective and sustainable way to increase the MHL (improved knowledge, decreased stigma and positive help-seeking efficacy) of teachers in Tanzania. As this study replicated the results of a previous intervention in Malawi, consideration could be given to

We studied the relationships postprandially between triglyceride-rich lipoprotein (TRL) and high-density lipoprotein (HDL) in 11 mixed hyperlipoproteinemia (MHL) and 11 hypercholesterolemia (HCL) patients. The high and prolonged postprandial triglyceridemia response observed in MHL but not HCL patients was essentially dependent on very-low-density lipoprotein (VLDL) changes. This abnormal response was related to decreased lipoprotein lipase (LPL) activity (-48.7%, P<.01) in MHL compared with HCL subjects. Cholesteryl ester transfer protein (CETP) activity was postprandially enhanced only in MHL patients, and this elevation persisted in the late period (+19% at 12 hours, P<.05), sustaining the delayed enrichment of VLDL with cholesteryl ester (CE). The late postprandial period in MHL patients was also characterized by high levels of apolipoprotein B (apoB)-containing lipoproteins with apoCIII ([LpB:CIII] +36% at 12 hours, P<.01) and decreased levels of apoCIII contained in HDL ([LpCIII-HDL] -34% at 12 hours, P<.01), reflecting probably a defective return of apoCIII from TRL toward HDL. In MHL compared with HCL patients, decreased HDL2 levels were related to both HDL2b and HDL2a subpopulations (-57% and -49%, respectively, P<.01 for both) and decreased apoA-I levels (-53%, P<.01) were equally linked to decreased HDL2 with apoA-I only (LpA-I) and HDL2 with both apoA-I and apoA-II ([LpA-I:A-II] -55% and -52%, respectively, P<.01 for both). The significant inverse correlations between the postprandial magnitude of LpB:CIII and HDL2-LpA-I and HDL2b levels in MHL patients underline the close TRL-HDL interrelationships. Our findings indicate that TRL and HDL abnormalities evidenced at fasting were postprandially amplified, tightly interrelated, and persistent during the late fed period in mixed hyperlipidemia. Thus, these fasting abnormalities are likely postprandially originated and may constitute proatherogenic lipoprotein disorders additional to the HCL in MHL patients.

 Mental health legislation (MHL) is required to ensure a regulatory framework for mental health services and other providers of treatment and care, and to ensure that the public and people with a mental illness are afforded protection from the often-devastating consequences of mental illness.  To provide an overview of evidence on the significance of MHL for successful primary care for mental health and community mental health servicesMethod: A qualitative review of the literature on the significance of MHL for successful primary care for mental health and community mental health services was conducted.  In many countries, especially in those who have no MHL, people do not have access to basic mental health care and treatment they require. One of the major aims of MHL is that all people with mental disorders should be provided with treatment based on the integration of mental health care services into the primary healthcare (PHC). In addition, MHL plays a crucial role in community integration of persons with mental disorders, the provision of care of high quality, the improvement of access to care at community level. Community-based mental health care further improves access to mental healthcare within the city, to have better health and mental health outcomes, and better quality of life, increase acceptability, reduce associated social stigma and human rights abuse, prevent chronicity and physical health comorbidity will likely to be detected early and managed.  Mental health legislation plays a crucial role in community integration of persons with mental disorders, integration of mental health at primary health care, the provision of care of high quality and the improvement of access to care at community level. It is vital and essential to have MHL for every country.

The objective of this study was to assess the relationship between superior semicircular canal dehiscence (SSCD) and hearing impairment. We retrospectively compared the prevalence of SSCD in the ears classified as conductive hearing loss (CHL), mixed hearing loss (MHL), and normal hearing status using submillimetric temporal bone computed tomography (TBCT) on the basis of coronal and additional reformatted planes dedicated to SSCD. From the patients with CHL (n = 127) and MHL (n = 45), the overall prevalence of SSCD in the ears classified as CHL, MHL, and normal hearing status were 6.6%, 7.2%, and 3.0%, respectively. Furthermore, the odds ratio for SSCD in the absence of any cause of hearing loss (eg, dysfunction of the tympanic membrane or middle ear, TBCT abnormalities, otosclerosis, trauma, surgery) was 5.35 in MHL (4/27; P = 0.037, 95% confidence interval, 1.1-25.81) and 3.31 in CHL (5/61; P = 0.115, 95% confidence interval, 0.75-14.63), compared with normal hearing status. Bony covering of the SSC should be specifically evaluated in patients with hearing impairment using submillimetric TBCT.

This study examined joint engagement and emotional availability of parent-child interactions for toddlers with moderate hearing loss (MHL) compared with toddlers with normal hearing (NH) and in relation to children's language abilities. The participants in this study were 25 children with MHL (40 to 60 dB hearing loss) and 26 children with NH (mean age: 33.3 months). The children and their parents were filmed during a 10-minute free play session in their homes. The duration of joint engagement and success rate of initiations were coded next to the level of emotional availability reflected by the Emotional Availability Scales. Receptive and expressive language tests were administered to the children to examine their language ability. Groups differed in joint engagement: children with MHL and their parents were less successful in establishing joint engagement and had briefer episodes of joint engagement than children with NH and their parents. No differences between groups were found for emotional availability measures. Both joint engagement and emotional availability measures were positively related to children's language ability. Children with MHL and their parents are emotional available to each other. However, they have more difficulties in establishing joint engagement with each other and have briefer episodes of joint engagement compared with children with NH and their parents. The parent-child interactions of children with better language abilities are characterized with higher levels of emotional availability and longer episodes of joint engagement. The results imply that interactions of children with MHL and their parents are an important target for family-centered early intervention programs.

Improving knowledge and beliefs about mental health (or mental health literacy [MHL]) may promote appropriate help-seeking by adolescents who are suffering from mental health problems. We developed a concise, school-staff-led MHL program and examined its effects. The participants comprised 118 grade-9 students (61 boys and 57 girls). The program consisted of two 50-min sessions, and was given by a schoolteacher. The effects of the program were evaluated before, immediately after and 3 months after the program, using a self-report questionnaire. Knowledge of mental health/illnesses and desirable behavior for help-seeking were significantly improved immediately after (post-test, P mental health problems were also significantly (P school-staff-led program may have a significant effect on the improvement of MHL in secondary school students. © 2015 The Authors.

Mental Health Literacy (MHL), namely recognition, and beliefs about treatment concerning Anorexia Nervosa (AN) were examined in a community sample of male and female (n = 983) aged 15-94 years. A vignette describing a women suffering from the symptoms of AN was presented, followed by a respondent-based structured interview concerning recognition of the problem and treatment beliefs. The majority of participants could identify the problem as that of an eating disorder, although only 16.1% could specifically identify it as AN. Many also believed the problem was primarily one of low self-esteem (32.5%). General practitioners and psychiatrists or psychologists were considered the most helpful treatment providers, while obtaining information about the problem and available services, followed by family therapy, were considered the most helpful treatments. Less than one-third of participants believed complete recovery was possible. Better AN MHL was found in younger, higher educated, and metropolitan domiciled females. This study offers encouraging results in regard to AN MHL. In particular, there was moderate regard for the use of mental health specialists in the treatment of the disorder. However, there appears to be a misconception that AN is largely the manifestation of low self-esteem and confusion concerning the distinction between AN and bulimia nervosa. AN MHL was poorer in males and those with higher social and health disadvantage. Copyright © 2010 Wiley Periodicals, Inc.

To describe how the Advanced Practice Nurse (APN) is uniquely suited to meet the needs of older adults throughout the continuum of cancer, to explore the progress that APNs have made in gero-oncology care, and make suggestions for future directions. Google Scholar, PubMed, and CINAHL. Search terms included: "gero-oncology," "geriatric oncology," "Advanced Practice Nurse," "Nurse Practitioner," "older adult," "elderly," and "cancer." Over the last decade, APNs have made advances in caring for older adults with cancer by playing a role in prevention, screening, and diagnosis; through evidence-based gero-oncology care during cancer treatment; and in designing tailored survivorship care models. APNs must combat ageism in treatment choice for older adults, standardize comprehensive geriatric assessments, and focus on providing person-centered care, specifically during care transitions. APNs are well-positioned to help understand the complex relationship between risk factors, geriatric syndromes, and frailty and translate research into practice. Palliative care must expand beyond specialty providers and shift toward APNs with a focus on early advanced care planning. Finally, APNs should continue to establish multidisciplinary survivorship models across care settings, with a focus on primary care. Copyright © 2015 Elsevier Inc. All rights reserved.

Extensive possibilities of applications have made emotion recognition ineluctable and challenging in the field of computer science. The use of non-verbal cues such as gestures, body movement, and facial expressions convey the feeling and the feedback to the user. This discipline of Human-Computer Interaction places reliance on the algorithmic robustness and the sensitivity of the sensor to ameliorate the recognition. Sensors play a significant role in accurate detection by providing a very high-quality input, hence increasing the efficiency and the reliability of the system. Automatic recognition of human emotions would help in teaching social intelligence in the machines. This paper presents a brief study of the various approaches and the techniques of emotion recognition. The survey covers a succinct review of the databases that are considered as data sets for algorithms detecting the emotions by facial expressions. Later, mixed reality device Microsoft HoloLens (MHL) is introduced for observing emotion recognition in Augmented Reality (AR). A brief introduction of its sensors, their application in emotion recognition and some preliminary results of emotion recognition using MHL are presented. The paper then concludes by comparing results of emotion recognition by the MHL and a regular webcam.

Mental health literacy (MHL), or the knowledge and abilities necessary to benefit mental health, is a significant determinant of mental health and has the potential to benefit both individual and public mental health. MHL and its measures have traditionally focused on knowledge and beliefs about mental -ill-health rather than on mental health. No measures of MHL addressing knowledge of good or positive mental health have been identified. This study aimed to develop and validate an instrument measuring adolescents' knowledge of how to obtain and maintain good mental health and to evaluate the psychometric properties of the instrument. More specifically, the factor structure, internal and construct validity, and test-retest reliability were assessed. The participants were Norwegian upper secondary school students aged 15-21 years. The development and validation of the instrument entailed three phases: 1) item generation based on the basic psychological needs theory (BPNT), focus group interviews, and a narrative literature review, 2) a pilot study (n = 479), and 3) test-retest (n = 149), known-groups validity (n = 44), and scale construction, item reduction through principal component analysis (PCA), and confirmatory factor analysis (CFA) for factor structure and psychometric properties assessment (n = 1888). Thirty-two items were initially generated, and 15 were selected for the pilot study. PCA identified cross-loadings, and a one-factor solution was examined.

Differential effect of combined lipase deficiency (cld/cld) on human hepatic lipase and lipoprotein lipase secretion.

Science.gov (United States)

Boedeker, J C; Doolittle, M H; White, A L

2001-11-01

Combined lipase deficiency (cld) is a recessively inherited disorder in mice associated with a deficiency of LPL and hepatic lipase (HL) activity. LPL is synthesized in cld tissues but is retained in the endoplasmic reticulum (ER), whereas mouse HL (mHL) is secreted but inactive. In this study we investigated the effect of cld on the secretion of human HL (hHL) protein mass and activity. Differentiated liver cell lines were derived from cld mice and their normal heterozygous (het) littermates by transformation of hepatocytes with SV40 large T antigen. After transient transfection with lipase expression constructs, secretion of hLPL activity from cld cells was only 12% of that from het cells. In contrast, the rate of secretion of hHL activity and protein mass per unit of expressed hHL mRNA was identical for the two cell lines. An intermediate effect was observed for mHL, with a 46% reduction in secretion of activity from cld cells. The ER glucosidase inhibitor, castanospermine, decreased secretion of both hLPL and hHL from het cells by approximately 70%, but by only approximately 45% from cld cells. This is consistent with data suggesting that cld may result from a reduced concentration of the ER chaperone calnexin. In conclusion, our results demonstrate a differential effect of cld on hLPL, mHL, and hHL secretion, suggesting differential requirements for activation and exit of the enzymes from the ER.

The lighting represents a consumption of about 19% of the world electricity production. We are thus searching new effective and environment-friendlier light sources. The ceramic metal-halide high intensity lamps (C-MHL) are one of the options for illuminating very high area. The new C-MHL lamps contain additives species that reduce mercury inside and lead to a richer spectrum in specific spectral intervals, a better colour temperature or colour rendering index. This work is particularly focused on the power radiated by these lamps, estimated using the net emission coefficient, and depending on several additives (calcium, sodium, tungsten, dysprosium, and thallium or strontium iodides). The results show the strong influence of the additives on the power radiated despite of their small quantity in the mixtures and the increase of visible radiation portion in presence of dysprosium.

2018-02-01

Failure analysis was carried out on a prematurely failed tertiary superheater tube used in gas-fired boiler. The analysis includes a comparative study of visual examination, chemical composition, hardness and microstructure at failed region, adjacent and far to failure as well as on fresh tube. The chemistry was found matching to the standard specification, whereas the hardness was low in failed tube compared to the fish mouth opening region and the fresh tube. Microscopic examination of failed sample revealed the presence of spheroidal carbides of Cr and Mo predominantly along the grain boundaries. The primary cause of failure is found to be localized heating. Magnetic hysteresis loop (MHL) measurements were carried out to correlate the magnetic parameters with microstructure and mechanical properties to establish a possible non-destructive evaluation (NDE) for health monitoring of the tubes. The coercivity of the MHL showed a very good correlation with microstructure and mechanical properties deterioration enabling a possible NDE technique for the health monitoring of the tubes.

The aim of this study was to assess the feasibility of a psychosis information intervention for professionals in contact with young people in Ireland. A quasi-experimental pre- and post-intervention design was used. One thousand and thirty-two professionals received an information intervention designed to improve mental health literacy (MHL) and confidence in providing help to people with psychosis. Seven hundred and fifty-five participants completed the Psychosis Information and Confidence Questionnaire pre- and post-intervention. The information intervention significantly improved participants': (1) knowledge of psychosis; (2) ability to recognize signs and symptoms of psychosis; (3) awareness of how to access services; and (4) confidence in providing help to people experiencing psychosis. Findings provide promising support for the intervention's feasibility and acceptability. The intervention enhanced MHL regarding psychosis among professionals in contact with young people. Further research assessing if such improvements translate to the facilitation of appropriate help seeking, the enhanced early detection of psychosis and a reduction of the duration of untreated psychosis is required. © 2017 John Wiley & Sons Australia, Ltd.

Typically, the synthesis of radiometal-based radiopharmaceuticals is performed in buffered aqueous solutions. We found that the presence of organic solvents like ethanol increased the radiolabeling yields of [ 68 Ga]Ga-DOTA (DOTA = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacatic acid). In the present study, the effect of organic cosolvents [ethanol (EtOH), isopropyl alcohol, and acetonitrile] on the radiolabeling yields of the macrocyclic chelator DOTA with several trivalent radiometals (gallium-68, scandium-44, and lutetium-177) was systematically investigated. Various binary water (H 2 O)/organic solvent mixtures allowed the radiolabeling of DOTA at a significantly lower temperature than 95 °C, which is relevant for the labeling of sensitive biological molecules. Simultaneously, much lower amounts of the chelators were required. This strategy may have a fundamental impact on the formulation of trivalent radiometal-based radiopharmaceuticals. The equilibrium properties and formation kinetics of [M(DOTA)] - (M III = Ga III , Ce III , Eu III , Y III , and Lu III ) complexes were investigated in H 2 O/EtOH mixtures (up to 70 vol % EtOH). The protonation constants of DOTA were determined by pH potentiometry in H 2 O/EtOH mixtures (0-70 vol % EtOH, 0.15 M NaCl, 25 °C). The log K 1 H and log K 2 H values associated with protonation of the ring N atoms decreased with an increase of the EtOH content. The formation rates of [M(DOTA)] - complexes increase with an increase of the pH and [EtOH]. Complexation occurs through rapid formation of the diprotonated [M(H 2 DOTA)] + intermediates, which are in equilibrium with the kinetically active monoprotonated [M(HDOTA)] intermediates. The rate-controlling step is deprotonation (and rearrangement) of the monoprotonated intermediate, which occurs through H 2 O ( *M(HL) k H 2 O ) and OH - ( *M(HL) k OH ) assisted reaction pathways. The rate constants are essentially independent of the EtOH concentration, but the M(HL) k H2O

Disentangling natural and anthropogenic signals in lacustrine records: An example from the Ilan Plain, NE Taiwan

Directory of Open Access Journals (Sweden)

Full Text Available The impact of human activities has been increasing to a degree where humans now outcompete many natural processes. When interpreting environmental and climatic changes recorded in natural archives on historical time scales, it is therefore important to be able to disentangle the relative contribution of natural and anthropogenic processes. Lake Meihua on the Ilan Plain in northeastern Taiwan offers a particularly suitable opportunity to test how human activities known from historical records can be recorded in lacustrine sediment. For this purpose, three cores from Lake Meihua have been studied by a multiproxy approach, providing the first decadal-resolution lacustrine records covering the past 150 years in Taiwan. Profiles of excess 210Pb, 137Cs and 239,240Pu from two short cores (MHL-09-01 and MHL-11-02 allowed a precise chronology to be established. The presence of a yellow, earthy layer with lower levels of organic material coincide with the record of land development associated with the construction of the San-Chin-Gong Temple during AD 1970-1982. Furthermore, in the lower part of the cores, the upwards increasing trend of inc/coh, TOC, TOC/TN, and grain size, coupled with the palynological data (increase of Alnus, Mallotus, Trema and herbs from the nearby core MHL-5A with radiocarbon chronology, suggest that the area surrounding the lake has been significantly affected by agricultural activities since the arrival of Chinese settlers around ~AD 1874. In sum, this study demonstrates that this suite of lacustrine sediments in northeastern Taiwan has recorded human activities in agreement with historical documents, and that different human activities will leave distinct sedimentological, geochemical, and palynological signatures in the sedimentary archives. Therefore, multiproxy reconstructions are important to capture the complex nature of human-environmental interactions. A better understanding of the weathering and erosion response to human

Mental health literacy (MHL) refers to an individuals' knowledge and beliefs about mental disorders that aid their recognition, management, and prevention. This study aims to investigate the MHL of depression among public health and sociology undergraduate students in Hanoi, Vietnam. A cross-sectional survey was carried out from May to September 2015. Data was collected using an anonymous, self-administered questionnaire distributed to 350 undergraduate students (213 public health majors; 137 sociology majors). Questions about MHL of depression were adapted from the Australian National Survey of Mental Health Literacy and Stigma. Question topics included recognition of depression, help-seeking intentions, first-aid support, and knowledge about interventions to help people with depression. Chi squared tests were conducted to compare proportional statistics across groups for multiple measures. With regard to recognition of mental disorders, 32.0% of the respondents used the accurate label "depression" for the vignette. Among those who correctly identified depression, 82.1% would seek help. The corresponding statistic was 81.1% from those who did not recognize depression. Both groups would seek help from counselor, psychologist, family members, and close friends. First-aid support suggested by the respondents in both groups were informal sources ( to listen to her problem in an understanding way, to encourage her to be more physically active , etc.). The interventions considered most helpful by the respondents were self-help strategies such as learning how to relax , getting physically active , doing exercise early in the morning , and reading a self - help book . Joining a group of individuals with similar problems was chosen to be a helpful intervention among those who did not recognize depression (p depression believed that people with depression should be admitted to hospital for psychiatric treatment (p depression among undergraduate students in Vietnam.

Thorium valency in molten alkali halides in equilibrium with metallic thorium

International Nuclear Information System (INIS)

Smirnov, M.V.; Kudyakov, V.Ya.

1983-01-01

Metallic thorium is shown to corrode in molten alkali halides even in the absence of external oxidizing agents, alkali cations acting as oxidizing agents. Its corrosion rate grows in the series of alkali chlorides from LiCl to CsCl at constant temperature. Substituting halide anions for one another exerts a smaller influence, the rate rising slightly in going from chlorides to bromides and iodides, having the same alkali cations. Thorium valency is determined coulometrically, the metal being dissolved anodically in molten alkali halides and their mixtures. In fluoride melts it is equal to 4 but in chloride, bromide and iodide ones, as a rule, it has non-integral values between 4 and 2 which diminish as the temperature is raised, as the thorium concentration is lowered, as the radii of alkali cations decrease and those of halide anions increase. The emf of cells Th/N ThHlsub(n) + (1-N) MHl/MHl/C, Hlsub(2(g)) where Hl is Cl, Br or I, M is Li, Na, K, Cs or Na + K, and N < 0.05, is measured as a function of concentration at several temperatures. Expressions are obtained for its concentration dependence. The emf grows in the series of alkali chlorides from LiCl to CsCl, other conditions being equal. (author)

To review functional results and quality of life of the first patients implanted with a newly introduced bone conduction implant system. Retrospective chart analysis of 6 patients (6 ears) implanted for conductive hearing loss (CHL) and mixed hearing loss (MHL) in 1 tertiary referral center between July 2012 and February 2013. Implantation of a new bone conduction hearing device. Pure tone audiometry (air conduction and bone conduction thresholds, pure tone average, air-bone gap, and functional gain), speech audiometry (Freiburg Monosyllabic Test), intraoperative and postoperative complication rate, and patient satisfaction (Glasgow benefit inventory [GBI]) were assessed. Air-conduction pure tone average (PTA) was 58.8 ± 8.2 dB HL. Unaided average air-bone gap (ABG) was 33.3 ± 6.2 dB. Aided air-conduction PTA in sound field was 25.2 ± 5.1 dB HL. Aided average ABG was -0.3 ± 7.3 dB. Average functional gain was 33.6 ± 7.2 dB. Mean improvement of GBI was +36.1. No intraoperative complications occurred. During a follow-up period of 8.5 ± 2.2 months, no device failure and no need for revision surgery occurred. Audiometric results of the new bone conduction hearing system are satisfying and comparable to the results of devices that have been applied previously for CHL and MHL. Intraoperatively and postoperatively, no complications were noted.

Purpose: To investigate the impact of radiographic parameter and radiation technique on the volumetric dose of lung and heart for intact breast radiation. Methods and Materials: Forty patients with both two-dimensional (2D) and computed tomographic (CT) simulations were enrolled in the study. Central lung distance (CLD), maximal heart distance (MHD), and maximal heart length (MHL) were measured under virtual simulation. Four plans were compared for each patient. Plan A used a traditional 2D tangential setup. Plan B used clinical target volume (CTV) based three-dimensional (3D) planning. Both plans C and D used a combination of a medial breast field with shallow tangents. Plan D is a further modification of plan C. Results: Under the traditional tangential setup, the mean ipsilateral lung dose and volume at 20, 30, and 40 Gy correlated linearly with CLD (R = 0.85∼0.91). The mean ipsilateral lung dose (Gy) approximated 4 times the CLD value (cm), whereas the percentage volume (%) of ipsilateral lung at 20, 30, and 40 Gy was about 10 times the CLD (cm). The mean heart dose and percentage volume at 20, 30, and 40 Gy correlated with MHD (R = 0.76∼0.80) and MHL (R 0.65∼0.75). The mean heart dose (Gy) approximated 3 times the MHD value (cm), and the percentage volume (%) of the heart at 10, 20, 30, and 40 Gy was about 6 times MHD (cm). Radiation technique impacted lung and heart dose. The 3D tangential plan (plan B) failed to reduce the volumetric dose of lung and heart from that of the 2D plan (plan A). The medial breast techniques (plans C and D) significantly decreased the volume of lung and heart receiving high doses (30 and 40 Gy). Plan D further decreased the 20 Gy volumes. By use of the medial breast technique, the lung and heart dose were not impacted by original CLD and MHD/MHL. Therefore, the improvement from the tangential technique was more remarkable for patients with CLD ≥ 3.0 cm (p<0.001). Conclusions: The CLD and MHD impact the volumetric dose of

Miocene Tectonics at the Pannonian - Carpathian Transition: The Bogdan Voda - Dragos Voda fault system, northern Romania

Tischler, M.; Gröger, H.; Marin, M.; Schmid, S. M.; Fügenschuh, B.

2003-04-01

Tertiary tectonics in the Pannonian-Carpathian transition zone was dominated by opposed rotations of Alcapa and Tisza-Dacia, separated by the Mid-Hungarian lineament (MHL). While in the Pannonian basin the MHL is well known from geophysical and borehole data, its northeastern continuation remains a matter of discussion. Our field based study, located in the Maramures mountains of northern Romania, provides new kinematic data from the Bogdan Voda fault, a first order candidate for the prolongation of the MHL to the northeast. In the Burdigalian, the Pienides (unmetamorphic flysch nappes) were emplaced onto the autochthonous Paleogene flysch units. Kinematic data consistently indicate top to the SE-directed thrusting of the Pienides and selected imbrications in the autochthonous units. Between Langhian and Tortonian these thrust contacts were offset by the E-W trending Bogdan Voda fault and its eastern continuation, the Dragos-Voda fault. These two faults share a common polyphase history, at least since the Burdigalian. Kinematic data derived from mesoscale faults indicate sinistral strike-slip displacement, in good agreement with kinematics inferred from map view. The NE-SW trending Greben fault, another fault of regional importance, was coevally active as a normal fault. From stratigraphic arguments major activity of this fault system is constrained to the time interval between 16.4-10 Ma. While deformation is strongly concentrated in the sedimentary units, the easterly located basement units are affected by abundant minor faults of similar kinematics covering a wide area. These SW-NE trending strike slip faults feature a normal component and resemble an imbricate fan geometry. Since Burdigalian thrusting is consistently SE-directed on either side of the Bogdan-Dragos Voda fault, major post-Burdigalian differential rotations can be excluded for the northern and southern block respectively. Hydrothermal veins within Pannonian volcanic units are aligned along the

The Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) monthly global observations allowed derivation of a robust empirical photometric solution over a broad range of incidence, emission and phase (i, e, g) angles. Combining the WAC stereo-based GLD100 [1] digital terrain model (DTM) and LOLA polar DTMs [2] enabled precise topographic corrections to photometric angles. Over 100,000 WAC observations at 643 nm were calibrated to reflectance (I/F). Photometric angles (i, e, g), latitude, and longitude were calculated and stored for each WAC pixel. The 6-dimensional data set was then reduced to 3 dimensions by photometrically normalizing I/F with a global solution similar to [3]. The global solution was calculated from three 2°x2° tiles centered on (1°N, 147°E), (45°N, 147°E), and (89°N, 147°E), and included over 40 million WAC pixels. A least squares fit to a multivariate polynomial of degree 4 (f(i,e,g)) was performed, and the result was the starting point for a minimum search solving the non-linear function min[{1-[ I/F / f(i,e,g)] }2]. The input pixels were filtered to incidence angles (calculated from topography) shadowed pixels, and the output normalized I/F values were gridded into an equal-area map projection at 100 meters/pixel. At each grid location the median, standard deviation, and count of valid pixels were recorded. The normalized reflectance map is the result of the median of all normalized WAC pixels overlapping that specific 100-m grid cell. There are an average of 86 WAC normalized I/F estimates at each cell [3]. The resulting photometrically normalized mosaic provides the means to accurately compare I/F values for different regions on the Moon (see Nuno et al. [4]). The subtle differences in normalized I/F can now be traced across the local topography at regions that are illuminated at any point during the LRO mission (while the WAC was imaging), including at polar latitudes.

Most of the world's women living with human immunodeficiency virus (HIV) reside in sub-Saharan Africa. Although efforts to reduce mother-to-child transmission are underway, obtaining complete and accurate data from rural clinical sites to track progress presents a major challenge. To describe the acceptability and feasibility of mobile phones as a tool for clinic-based face-to-face data collection with pregnant women living with HIV in South Africa. As part of a larger clinic-based trial, 16 interviewers were trained to conduct mobile phone-assisted personal interviews (MPAPI). These interviewers (participant group 1) completed the same short questionnaire based on items from the Technology Acceptance Model at 3 different time points. Questions were asked before training, after training, and 3 months after deployment to clinic facilities. In addition, before the start of the primary intervention trial in which this substudy was undertaken, 12 mothers living with HIV (MLH) took part in a focus group discussion exploring the acceptability of MPAPI (participant group 2). Finally, a sample of MLH (n=512) enrolled in the primary trial were asked to assess their experience of being interviewed by MPAPI (participant group 3). Acceptability of the method was found to be high among the 16 interviewers in group 1. Perceived usefulness was reported to be slightly higher than perceived ease of use across the 3 time points. After 3 months of field use, interviewer perceptions of both perceived ease of use and perceived usefulness were found to be higher than before training. The feasibility of conducting MPAPI interviews in this setting was found to be high. Network coverage was available in all clinics and hardware, software, cost, and secure transmission to the data center presented no significant challenges over the 21-month period. For the 12 MHL participants in group 2, anxiety about the multimedia capabilities of the phone was evident. Their concern centered on the

Full Text Available Mental health literacy (MHL is considered a prerequisite for early recognition and intervention in mental disorders, and for this reason, it has become a focus of research over the past few decades. Assessing this construct is relevant for identifying knowledge gaps and erroneous beliefs concerning mental health issues, to inform the development of interventions aimed at promoting mental health literacy as well as the evaluation of these interventions. Recently, we developed a new self-reporting measure (MHLq for assessing mental health literacy in young people (12–14 years-old, meeting the need to assess MHL from a comprehensive perspective of the construct instead of focusing on a restricted number of mental disorders or specific dimensions (e.g., knowledge concerning specific disorders; stigma. The present study aimed to adapt the MHLq for the young adult population and to examine its psychometric properties, according to the following steps: (1 item adaptation, using a think aloud procedure (n = 5; (2 data collection (n = 356, aged between 18 and 25 years old; and (3 psychometric analyses (exploratory factor analysis and internal consistency analysis. The final version of the questionnaire included 29 items (total scale α = 0.84, organized by four dimensions: (1 knowledge of mental health problems (α = 0.74; (2 erroneous beliefs/stereotypes (α = 0.72; (3 help-seeking and first aid skills (α = 0.71; and (4 self-help strategies (α = 0.60. The results suggest that the MHLq-adult form is a practical, valid, and reliable screening tool for identifying gaps in knowledge, beliefs, and behavioral intentions related to mental health and mental disorders, planning promotion programs, and evaluating intervention effectiveness.

Full Text Available The historical museums, such as the monuments, have been understood as images the societies produce for the future. However, this concept of museums as maintainers and guardians of the memory of a community or a locality is been revised. The city of Londrina, even though fairly new, preserves by various means a praise of the memory of certain groups, called 'pioneers'. The challenging of such memorial practices and inclusion of new actors is quite controversial and costly. Thus, this paper aims to reflect on the representations of women in the language of the Historical Museum of Londrina. To this end, it is proposed to analyze a temporary exhibition placed in that Museum: "Caring, Healing, Remember - memory of the health in Londrina." Therefore, we will investigate what (s language (s the MHL aligns to and presents itself for the public.

Smartphones have become necessities in people' lives, so that many more public charging stations are under deployment worldwide to meet the increasing demand of phone charging (i.e., in airports, subways, shops, etc). However, this situation may expose a hole for cyber-criminals to launch various...... attacks especially charging attacks and threaten user's privacy. As an example, juice filming charging (JFC) attack is able to steal users' sensitive and private information from both Android OS and iOS devices, through automatically recording phone-screen and monitoring users' inputs during the whole...... charging period. More importantly, this attack does not need any permission or installing any pieces of apps on user's side. The rationale is that users' information can be leaked through a standard micro USB connector that employs the Mobile High-Definition Link (MHL) standard. Motivated by the potential...

Three DTPA-derivative ligands, the non-substituted DTPA-bis(amide) (L(0)), the mono-substituted DTPA-bis(n-butylamide) (L(1)) and the di-substituted DTPA-bis[bis(n-butylamide)] (L(2)) were synthesized. The stability constants of their Gd3+ complexes (GdL) have been determined by pH-potentiometry with the use of EDTA or DTPA as competing ligands. The endogenous Cu2+ and Zn2+ ions form ML, MHL and M(2)L species. For the complexes CuL(0) and CuL(1) the dissociation of the amide hydrogens (CuLH(-1)) has also been detected. The stability constants of complexes formed with Gd3+, Cu2+ and Zn2+ increase with an increase in the number of butyl substituents in the order ML(0) DTPA)2-, while the complex GdL2 possesses a much higher kinetic stability.

Annual community-directed treatment with ivermectin (CDTI) have been carried out since 1999 in the Lekie division (central region of Cameroon where most cases of Loa-related post ivermectin severe adverse events were reported) as part of the joined activities of the African Programme for Onchocerciasis Control (APOC) and Mectizan® Donation Program (MDP). As large-scale administration of ivermetine was demonstrated to be an efficient means to control loiasis transmission, it was hypothesized that CDTI would have lowered or halted the transmission of Loa loa in the Lekie division after 13 years of annual drug administration, indicating a possible reduction in the occurrence of Loa-related post-ivermectin severe adverse events. A 4-month entomologic study was carried out from March to June 2012 in the Lekie division to evaluate the impact of 13 years of CDTI on the transmission of L. loa whose baseline data were recorded in 1999-2000. There was a significant reduction in the infection rate for Chrysops silacea and C. dimidiata from 6.8 and 9% in 1999-2000 to 3 and 3.6% in 2012, respectively. The differences in the infective rate (IR) (percentage of flies harboring head L3 larvae), potential infective rate (PIR) (percentage of flies bearing L3 larvae), mean head L3 larvae load (MHL3) (average L3 per infective fly) and mean fly L3 larvae load (MFL3) (average L3 per potentially infective fly) for both C. silacea and C. dimidiata were not significantly different between the two investigation periods. The biting density (BD) was almost three-fold higher in 2012 for C. silacea but not for C. dimidiata. The transmission potential (TP) which is a function of the BD, was higher in the present study than in the baseline investigation for each species. The infection rate remaining high, the high TP and the stability observed in the IR, PIR, MHL3 and MFL3 after 13 years of CDTI suggest that transmission of L. loa is still active. This is an indication that the risk of occurrence

Highlights: ► Four kinds of mannitol–fatty acid esters were synthesized as novel organic PCMs for thermal energy storage applications. ► The synthesized PCMs were characterized using FT-IR, 1 H NMR, 13 C NMR, DSC and TGA methods and thermal cycling test. ► The melting temperatures and latent heat values of the PCMs were in the range of 42–65 °C and 145–202 J/g, respectively. ► Thermal conductivity of the PCMs was increased significantly by addition of EG with especially 10 wt%. ► The synthesized PCMs are promising organic PCMs for solar heating applications. - Abstract: In this study, four kinds of mannitol–fatty acid esters were synthesized as novel organic phase change materials (PCMs) for thermal energy storage applications. The structural characterization of synthesized mannitol hexastearate (MHS), mannitol hexapalmitate (MHP), mannitol hexamyristate (MHM) and mannitol hexalaurate (MHL) were carried out using Fourier Transform Infrared (FT-IR), Proton Nuclear Magnetic Resonance ( 1 H NMR), and 13 C NMR spectroscopy methods. Thermal energy storage properties and thermal reliability of the synthesized PCMs were determined using differential scanning calorimetry (DSC) method at a heating rate of 1 °C/min. DSC results showed that the melting temperatures of the PCMs were in the temperature range of 42–65 °C and their latent heat values spanned between 145 and 202 J/g. The latent heats of these PCMs are low compared to mannitol but they fall into the same range as fatty acids. The synthesized PCMs have much lower phase change temperatures and supercooling degree (about 1–8 °C) and compared to the mannitol. They have also better odor, noncorrosivity and thermal durability properties as compared to the fatty acids. Thermal cycling test consisted of repeated 1000 melting/solidification cycles also revealed that the synthesized PCMs have good thermal reliability. In addition, thermal conductivity of the PCMs was increased significantly by

This book is aimed at researchers and students who would like to engage in and deepen their understanding of design cognition research. The book presents new approaches for analyzing design thinking and proposes methods of measuring design processes. These methods seek to quantify design issues and design processes that are defined based on notions from the Function-Behavior-Structure (FBS) design ontology and from linkography. A linkograph is a network of linked design moves or segments. FBS ontology concepts have been used in both design theory and design thinking research and have yielded numerous results. Linkography is one of the most influential and elegant design cognition research methods. In this book Kan and Gero provide novel and state-of-the-art methods of analyzing design protocols that offer insights into design cognition by integrating segmentation with linkography by assigning FBS-based codes to design moves or segments and treating links as FBS transformation processes.

Full Text Available This article depicts a journey over the decades to address some of the needs of children and families in the child welfare system. Recounting a few key milestones and challenges in the past 40 years, it is argued that workforce development is one key to improved outcomes for abused and neglected children and their families. Major events and several turning points are chronicled. Emerging workforce needs in aging are also cited as lessons learned from child welfare have implications for building a gero savvy social work workforce. Funding streams involving IV-E and Medicaid are discussed. It is argued that workforce development can be a life and death issue for some of these most vulnerable populations. Thus, the workforce development agenda must be at the forefront of the social work profession for the 21st century. Key funding streams are needed to foster investments in building and sustaining the social work workforce.

DNA Mismatch Repair System: Repercussions in Cellular Homeostasis and Relationship with Aging

Directory of Open Access Journals (Sweden)

Juan Cristóbal Conde-Pérezprina

2012-01-01

Full Text Available The mechanisms that concern DNA repair have been studied in the last years due to their consequences in cellular homeostasis. The diverse and damaging stimuli that affect DNA integrity, such as changes in the genetic sequence and modifications in gene expression, can disrupt the steady state of the cell and have serious repercussions to pathways that regulate apoptosis, senescence, and cancer. These altered pathways not only modify cellular and organism longevity, but quality of life (“health-span”. The DNA mismatch repair system (MMR is highly conserved between species; its role is paramount in the preservation of DNA integrity, placing it as a necessary focal point in the study of pathways that prolong lifespan, aging, and disease. Here, we review different insights concerning the malfunction or absence of the DNA-MMR and its impact on cellular homeostasis. In particular, we will focus on DNA-MMR mechanisms regulated by known repair proteins MSH2, MSH6, PMS2, and MHL1, among others.

The Global Navigation Satellite System (GNSS) reflectometry, i.e. GNSS-R, is a novel remote-sensing technique first published in that uses GNSS signals reflected from the Earth's surface to infer its surface properties such as sea surface height (SSH), ocean winds, sea-ice coverage, vegetation, wetlands and soil moisture, to name a few. This communication discusses the scientific value of GNSS-R to (a) furthering our understanding of ocean mesoscale circulation toward scales finer than those that existing nadir altimeters can resolve, and (b) mapping vegetated wetlands, an emerging application that might open up new avenues to map and monitor the planet's wetlands for methane emission assessments. Such applications are expected to be demonstrated by the availability of data from GEROS-ISS, an ESA experiment currently in phase A, and CyGNSS [3], a NASA mission currently in development. In particular, the paper details the expected error characteristics and the role of filtering played in the assimilation of these data to reduce the altimetric error (when averaging many measurements).

This work addresses the accuracy of the Global Navigation Satellite Systems (GNSS)-Reflectometry (GNSS-R) scatterometric measurements considering the presence of both coherent and incoherent scattered components, for both conventional GNSS-R (cGNSS-R) and interferometric GNSS-R (iGNSS-R) techniques. The coherent component is present for some type of surfaces, and it has been neglected until now because it vanishes for the sea surface scattering case. Taking into account the presence of both scattering components, the estimated Signal-to-Noise Ratio (SNR) for both techniques is computed based on the detectability criterion, as it is done in conventional GNSS applications. The non-coherent averaging operation is considered from a general point of view, taking into account that thermal noise contributions can be reduced by an extra factor of 0.88 dB when using partially overlapped or partially correlated samples. After the SNRs are derived, the received waveform's peak variability is computed, which determines the system's capability to measure geophysical parameters. This theoretical derivations are applied to the United Kingdom (UK) TechDemoSat-1 (UK TDS-1) and to the future GNSS REflectometry, Radio Occultation and Scatterometry on board the International Space Station (ISS) (GEROS-ISS) scenarios, in order to estimate the expected scatterometric performance of both missions.

For the past several decades, research in understanding the molecular basis of human aging has progressed significantly with the analysis of premature aging syndromes. Progerin, an altered form of lamin A, has been identified as the cause of premature aging in Hutchinson-Gilford Progeria Syndrome (HGPS), and may be a contributing causative factor in normal aging. However, the question of whether HGPS actually recapitulates the normal aging process at the cellular and organismal level, or simply mimics the aging phenotype is widely debated. In the present study we analyzed publicly available microarray datasets for fibroblasts undergoing cellular aging in culture, as well as fibroblasts derived from young, middle-age, and old-age individuals, and patients with HGPS. Using GeroScope pathway analysis and drug discovery platform we analyzed the activation states of 65 major cellular signaling pathways. Our analysis reveals that signaling pathway activation states in cells derived from chronologically young patients with HGPS strongly resemble cells taken from normal middle-aged and old individuals. This clearly indicates that HGPS may truly represent accelerated aging, rather than being just a simulacrum. Our data also points to potential pathways that could be targeted to develop drugs and drug combinations for both HGPS and normal aging.

Considered a public health issue, the prevalence and severity of poor mental well-being on college campuses has continued to rise. While many college campuses offer mental health counseling services, and utilization rates are increasing, their proportional usage is low especially among males, who often deal with poor mental well-being by adopting unhealthy coping strategies. The purpose of this study was to use the Information-Motivation-Behavioral Skills (IMB) model to assess the relationship between the determinants as factors that may impact help-seeking behaviors in a large sample ( n = 1,242) of male college students. Employing a cross-sectional study design, a 71-item online survey assessed information via total mental health literacy (MHL), motivation via attitudes toward mental health and subjective norms regarding mental health, and behavioral skills via intentions regarding help-seeking behaviors, and stigma. Results revealed correlations between information and motivation ( r = .363, p < .01), information and behavioral skills ( r = .166, p < .01), and motivation and behavioral skills ( r = .399, p < .01). Multiple regression was used to determine stigma is a mediator for all relationships. These findings represent an opportunity to take a public health approach to male mental health through developing multilayered interventions that address information, motivation, behavioral skills, and stigma.

The maritime environment presents a unique set of challenges to search and recovery (SAR) operations. There is a paucity of information available to guide provision of medical support for SAR operations for aircraft disasters at sea. The Republic of Singapore Navy (RSN) took part in two such SAR operations in 2014 which showcased the value of a military organization in these operations. Key considerations in medical support for similar operations include the resultant casualty profile and challenges specific to the maritime environment, such as large distances of area of operations from land, variable sea states, and space limitations. Medical support planning can be approached using well-established disaster management life cycle phases of preparedness, mitigation, response, and recovery, which all are described in detail. This includes key areas of dedicated training and exercises, force protection, availability of air assets and chamber support, psychological care, and the forensic handling of human remains. Relevant lessons learned by RSN from the Air Asia QZ8501 search operation are also included in the description of these key areas. Teo KAC , Chong TFG , Liow MHL , Tang KC .

Cow's milk protein allergy (CMPA) is being seen more frequently on a daily basis in pediatric consultations. It shares symptoms with gastroesophageal reflux (GER), which can complicate the differential diagnosis. To attempt to corroborate the presence of acid GER in children with CMPA, as well as to find a characteristic profile through the 24-hour pH monitoring study in children with GER and CMPA METHODS: The intraesophageal pH monitoring studies performed on 47 children with CMPA were reviewed. The measurements in all the studies were carried out within a 24-hour period using Digitrapper® equipment with a multi-use GeroFlex® catheter, after calibration with pH 7 and pH 1 buffer solutions. Of the 47 children, 23 were boys (32.4%) and 24 were girls (33.8%) and the mean age was 5±3.7 years. Fourteen of the 47 children (29%) presented with GER, according to the result of the 24-hour intraesophageal measurement. Only 2 of the 47 patients studied fit the phasic profile. The findings show the existing relation between the two pathologies. Nevertheless, it is important to determine the presence of non-acid or weak acid reflux, because their existence can increase this association.

Žemaitės feminizmas. Žemaitė’s Feminism

2009-01-01

Full Text Available The biography of Julija Beniuševičiūtė-Žymantie­nė – Žemaitė (1845–1921, one of the greatest Lithu­anian Realists, has got a broad accent of feminist ac­tivity. Some short stories written by Žemaitė express feminist ideas with publicistic pathos (In Town, „Mieste“, 1905, Mister Zigmantas, „Ponas Zigman­tas“, and others. In her short story Eve („Ieva“ Že­maitė presents an interesting ironic interpretation of the biblical archetype. Žemaitė’s best literary visions of women’s infelicity varies the topos of a quiet / silent / silenced woman and interestingly imply some gap between feminist ideology and literary meaning. In the short stories The Daughter-in-Law („Marti“, 1896, They Didn’t Have a Good Mother („Neturėjo geros motinos“, 1895 the reason of misfortunes se­ems to be deeper than just women being oppressed by men in the patriarchal society. The patriarchal op­pression of women is constructed as a metonymy of the philosophical evil. The short story Sutkai (1897 may be interpreted as a literary vision of a feminine utopia: woman’s identity here is defined rather as wholeness than “otherness”.

Full Text Available This work addresses the accuracy of the Global Navigation Satellite Systems (GNSS-Reflectometry (GNSS-R scatterometric measurements considering the presence of both coherent and incoherent scattered components, for both conventional GNSS-R (cGNSS-R and interferometric GNSS-R (iGNSS-R techniques. The coherent component is present for some type of surfaces, and it has been neglected until now because it vanishes for the sea surface scattering case. Taking into account the presence of both scattering components, the estimated Signal-to-Noise Ratio (SNR for both techniques is computed based on the detectability criterion, as it is done in conventional GNSS applications. The non-coherent averaging operation is considered from a general point of view, taking into account that thermal noise contributions can be reduced by an extra factor of 0.88 dB when using partially overlapped or partially correlated samples. After the SNRs are derived, the received waveform’s peak variability is computed, which determines the system’s capability to measure geophysical parameters. This theoretical derivations are applied to the United Kingdom (UK TechDemoSat-1 (UK TDS-1 and to the future GNSS REflectometry, Radio Occultation and Scatterometry on board the International Space Station (ISS (GEROS-ISS scenarios, in order to estimate the expected scatterometric performance of both missions.

La importancia de esta diferenciación radica en el tratamiento, que es ligeramente más agresivo en el FA y en el comportamiento biológico, ya que el FA puede derivar en un sarcoma ameloblástico, y el QF puede evolucionar hacia ameloblastoma y más raramente carcinoma mucoepidermoide.Abstract: Ameloblastic fibroma (AF is a mixed odontogenic tumor composed of mesenchymal tissue and odontogenic epithelium, accounting for 2% of all odontogenic tumors, while dentigerous or follicular cyst (FQ, second odontogenic cyst in frequency, is formed exclusivelly by soft conective tissue (mesenchyme. Nevertheless, hiperplastic fibrous sac may contain rests of odontogenic epithelium, showing a similar histologic pattern. The importance of an adequate differentiation lies in the treatment, which is slightly aggresive for AF, and regarding the biological behaviour of both lesions, since AF might become in an ameloblastic sarcoma, while over an FQ could develope an ameloblastoma or even a mucoepidermoid carcinoma.

Our understanding of somatic alterations in colon cancer has evolved from a concept of a series of events taking place in a single sequence to a recognition of multiple pathways. An oncogenetic tree is a model intended to describe the pathways and sequence of somatic alterations in carcinogenesis without assuming that tumors will fall in mutually exclusive categories. We applied this model to data on colon tumor somatic alterations. An oncogenetic tree model was built using data on mutations of TP53, KRAS2, APC, and BRAF genes, methylation at CpG sites of MLH1 and TP16 genes, methylation in tumor (MINT) markers, and microsatellite instability (MSI) for 971 colon tumors from a population-based series. Oncogenetic tree analysis resulted in a reproducible tree with three branches. The model represents methylation of MINT markers as initiating a branch and predisposing to MSI, methylation of MHL1 and TP16, and BRAF mutation. APC mutation is the first alteration in an independent branch and is followed by TP53 mutation. KRAS2 mutation was placed a third independent branch, implying that it neither depends on, nor predisposes to, the other alterations. Individual tumors were observed to have alteration patterns representing every combination of one, two, or all three branches. The oncogenetic tree model assumptions are appropriate for the observed heterogeneity of colon tumors, and the model produces a useful visual schematic of the sequence of events in pathways of colon carcinogenesis.

Fe (III - Galactomannan Solid and Aqueous Complexes: Potentiometric, EPR Spectroscopy and Thermal Data

Full Text Available Galactomannans can be employed in food industries to modify the final rheological properties of the products. Since they are not absorbed by the living organisms they can also be used in dietary foods. The equilibria involving the interactions of Fe(III and galactomannans and arabinogalactan of several leguminous plants were characterized by potentiometric titrations and EPR spectroscopy. The log of the equilibrium constants for the formation of ML species, where M is the metal ion and L is the monomeric unit of the biopolymers, were 15.4, 14.1 and 18.5, for the galactomannans of C. fastuosa, L. leucocephala and S. macranthera, respectively. Log K values for protonated species (MHL were 3.1, 3.3, and were not detected for the galactomannan of S. macranthera. The log K values for the formation of ML2 were 14.1, 13.3 and 15.2, respectively. Early formation of insoluble products in the equilibrium with arabinogalactan and Fe(III prevented acquisition of reliable data. The solid complexes assays showed a great dipolar interaction between two Fe(III ions in the inner structure of the biopolymer which increased as the degree of substitution of the galactomannan decreased, and also showed the resulting thermal stability. The complexes impart a new possibility of providing essential metal ions in dietary foods since decomplexation of the complexes can occur at different pH values existing in the human body.

Glasses produced from decompression experiments conducted by Fiege et al. (2014a) were used to investigate the fractionation of sulfur isotopes between fluid and andesitic melt upon magma degassing. Starting materials were synthetic glasses with a composition close to a Krakatau dacitic andesite. The glasses contained 4.55–7.95 wt% H2O, ∼140 to 2700 ppm sulfur (S), and 0–1000 ppm chlorine (Cl). The experiments were carried out in internally heated pressure vessels (IHPV) at 1030 °C and oxygen fugacities (fO2) ranging from QFM+0.8 log units up to QFM+4.2 log units (QFM: quartz–fayalite–magnetite buffer). The decompression experiments were conducted by releasing pressure (P) continuously from ∼400 MPa to final P of 150, 100, 70 and 30 MPa. The decompression rate (r) ranged from 0.01 to 0.17 MPa/s. The samples were annealed for 0–72 h (annealing time, tA) at the final P and quenched rapidly from 1030 °C to room temperature (T).The decompression led to the formation of a S-bearing aqueous fluid phase due to the relatively large fluid–melt partitioning coefficients of S. Secondary ion mass spectrometry (SIMS) was used to determine the isotopic composition of the glasses before and after decompression. Mass balance calculations were applied to estimate the gas–melt S isotope fractionation factor αg-m.No detectable effect of r and tA on αg-m was observed. However, SIMS data revealed a remarkable increase of αg-m from ∼0.9985 ± 0.0007 at >QFM+3 to ∼1.0042 ± 0.0042 at ∼QFM+1. Noteworthy, the isotopic fractionation at reducing conditions was about an order of magnitude larger than predicted by previous works. Based on our experimental results and on previous findings for S speciation in fluid and silicate melt a new model predicting the effect of fO2 on αg-m (or Δ34Sg–m) in andesitic systems at 1030 °C is proposed. Our experimental results as well as our modeling are of high importance for the interpretation of S isotope

E-mail: vivianmedvet@yahoo.com.br It is described a case of dentigerous cyst in a 2-year-old female pampa horse that showed swelling in the right temporal region and a draining tract near the right pinna. The diagnosis is established with clinical, radiographic and histopathological examination of the surrounding structures. Dentigerous cyst is an uncommon condition in horses and it occurs most frequently in young animals. Twelve 1,3-4 cm white firm structures were removed, some with central pulp canal and longitudinal grooves in the external surface, grossly resembling teeth. Microscopic examination showed a structure compatible with dental tissue lined by a non-keratinezed epithelium. A lympho-plasmocitary inflammatory reaction was also seem in the dermis. Differential diagnoses includes congenital deformities of the bone, trauma, abscess and perforating foreign bodies. Post- -operative complications include haemorrhage, fracture of the temporal bone and permanent neurological damage. This case highlights the importance of the investigation of recurrent abscess in horses that are resistant to antibiotics.

Electronic tissue compensation (eComp) is an external beam planning technique allowing user to manually generate dynamic beam fluence to produce more uniform or modulated dose distribution. In this study, we compared the effectiveness between conventional three-dimensional conformal radiotherapy (3DCRT) and eComp for whole breast irradiation. 3DCRT and eComp planning techniques were used to generate treatment plans for 60 whole breast patients, respectively. The planning goal was to cover 95% of the planning target volume (PTV) with 95% of the prescription dose while minimizing doses to lung, heart, and skin. Comparing to 3DCRT plans, on the average, eComp treatment planning process was about 7 minutes longer, but resulted in lower lung V20Gy, lower mean skin dose, with similar heart dose. The benefits were more pronounced for larger breast patients. Statistical analyses were performed between critical organ doses and patient anatomic features, i.e., central lung distance (CLD), maximal heart distance (MHD), maximal heart length (MHL) and breast separation (BS) to explore any correlations and planning method selection. It was found that to keep the lung V20Gy lower than 20% and mean skin dose lower than 85% of the prescription dose, eComp was the preferred method for patients with more than 2.3 cm CLD or larger than 22.5 cm BS. The study results may be useful in providing a handy criterion in clinical practice allowing us to easily choose between different planning techniques to satisfy the planning goal with minimal increase in complexity and cost.

"I'm Still Here": Resilience Among Older Survivors of Breast Cancer.

Pieters, Huibrie C

2016-01-01

Cancer presents a severe adversity that calls on intrinsic strength factors such as resilience. Breast cancer is especially common among older women. Understanding the interaction between the mechanisms of resilience and the psychosocial impact of cancer requires consideration of developmental age. This research explores resilience from the point of view of older women who recently completed treatment for early-stage breast cancer. Constructivist grounded theory directed data collection and analysis of 31 personal, semistructured interviews with 18 women aged 70 to 94 years. Faced with overcoming the adversity of a first cancer experience, participants rebounded and restored balance to their lives with a sense that they did the work of managing cancer with self-efficacy and autonomy. Resilience was evidenced as a multidimensional process containing a natural interaction of attributes. Self-reliance, optimism, and persevering were embedded in human interconnectedness. The process of cancer survivorship was positioned in the larger picture of the joys and hardships of having lived a long life. The core self continued through these changing times, connecting the past, present, and anticipated future, as exemplified by "I'm still here." Regaining balance required tenacity, pragmatism, and dedication to do the work that needed to be done to treat cancer and move on with life. Resilience is a valuable resource in strength-based approaches in healthcare. Practical examples for clinicians who follow a strength-based approach to promote adaptation for the continuing challenges of breast cancer survivorship among older women include acknowledging unique individual expressions of resilience. Gero-oncology is a salient field for multidisciplinary teams who seek to study resilience.

Human mismatch repair protein hMutLα is required to repair short slipped-DNAs of trinucleotide repeats.

Science.gov (United States)

Panigrahi, Gagan B; Slean, Meghan M; Simard, Jodie P; Pearson, Christopher E

2012-12-07

Mismatch repair (MMR) is required for proper maintenance of the genome by protecting against mutations. The mismatch repair system has also been implicated as a driver of certain mutations, including disease-associated trinucleotide repeat instability. We recently revealed a requirement of hMutSβ in the repair of short slip-outs containing a single CTG repeat unit (1). The involvement of other MMR proteins in short trinucleotide repeat slip-out repair is unknown. Here we show that hMutLα is required for the highly efficient in vitro repair of single CTG repeat slip-outs, to the same degree as hMutSβ. HEK293T cell extracts, deficient in hMLH1, are unable to process single-repeat slip-outs, but are functional when complemented with hMutLα. The MMR-deficient hMLH1 mutant, T117M, which has a point mutation proximal to the ATP-binding domain, is defective in slip-out repair, further supporting a requirement for hMLH1 in the processing of short slip-outs and possibly the involvement of hMHL1 ATPase activity. Extracts of hPMS2-deficient HEC-1-A cells, which express hMLH1, hMLH3, and hPMS1, are only functional when complemented with hMutLα, indicating that neither hMutLβ nor hMutLγ is sufficient to repair short slip-outs. The resolution of clustered short slip-outs, which are poorly repaired, was partially dependent upon a functional hMutLα. The joint involvement of hMutSβ and hMutLα suggests that repeat instability may be the result of aberrant outcomes of repair attempts.

REMEDIATION OF NITRATE-CONTAMINATED GROUNDWATER USING A BIOBARRIER

International Nuclear Information System (INIS)

STrietelmeir, B.

2000-01-01

A biobarrier system has been developed for use in remediating shallow alluvial groundwater. This barrier is made from highly porous materials that are relatively long-lasting, carbon-based (to supply a limiting nutrient in nitrate destruction, in most cases), and extremely inexpensive and easy to emplace. In a series of laboratory studies, we have determined the effectiveness of this barrier at destroying nitrate and perchlorate in groundwater from Mortandad Canyon at Los Alamos National Laboratory (LANL). This groundwater was obtained from a monitoring well, MCO-5, which is located in the flowpath of the discharge waters from the LANL Radioactive Liquid Waste Treatment Facility (RLWTF). Water with elevated nitrate levels has been discharged from this plant for many years, until recently when the nitrate levels have been brought under the discharge limits. However, the historical discharge has resulted in a nitrate plume in the alluvial groundwater in this canyon. The LANL Multi-Barrier project was initiated this past year to develop a system of barriers that would prevent the transport of radionuclides, metals, colloids and other contaminants, including nitrate and perchlorate, further down the canyon in order to protect populations down-gradient. The biobarrier. will be part of this Multi-Barrier system. We have demonstrated the destruction of nitrate at levels up to 6.5-9.7 mhl nitrate (400-600 mg/L), and that of perchlorate at levels of about 4.3 microM perchlorate (350 ppb). We have quantified the populations of microorganisms present in the biofilm that develops on the biobarrier. The results of this research will be discussed along with other potential applications of this system

GNSS reflectometry aboard the International Space Station: phase-altimetry simulation to detect ocean topography anomalies

2016-04-01

An ocean altimetry experiment using Earth reflected GNSS signals has been proposed to the European Space Agency (ESA). It is part of the GNSS Reflectometry Radio Occultation Scatterometry (GEROS) mission that is planned aboard the International Space Station (ISS). Altimetric simulations are presented that examine the detection of ocean topography anomalies assuming GNSS phase delay observations. Such delay measurements are well established for positioning and are possible due to a sufficient synchronization of GNSS receiver and transmitter. For altimetric purpose delays of Earth reflected GNSS signals can be observed similar to radar altimeter signals. The advantage of GNSS is the synchronized separation of transmitter and receiver that allow a significantly increased number of observation per receiver due to more than 70 GNSS transmitters currently in orbit. The altimetric concept has already been applied successfully to flight data recorded over the Mediterranean Sea. The presented altimetric simulation considers anomalies in the Agulhas current region which are obtained from the Region Ocean Model System (ROMS). Suitable reflection events in an elevation range between 3° and 30° last about 10min with ground track's length >3000km. Typical along-track footprints (1s signal integration time) have a length of about 5km. The reflection's Fresnel zone limits the footprint of coherent observations to a major axis extention between 1 to 6km dependent on the elevation. The altimetric performance depends on the signal-to-noise ratio (SNR) of the reflection. Simulation results show that precision is better than 10cm for SNR of 30dB. Whereas, it is worse than 0.5m if SNR goes down to 10dB. Precision, in general, improves towards higher elevation angles. Critical biases are introduced by atmospheric and ionospheric refraction. Corresponding correction strategies are still under investigation.

Purpose: To explore the correlations between anatomic features and dose-volumetric parameters in 3DCRT and eComp whole breast irradiation and identify the feasibility of anatomic parameters to predict the planning method selection. Methods: We compared the effectiveness between conventional three-dimensional conformal radiotherapy (3DCRT) and electronic tissue compensation (eComp) for whole breast irradiation. 3DCRT and eComp planning techniques were used to generate treatment plans for 60 whole breast patients, respectively. The planning goal was to cover 95% of the planning target volume (PTV) with 95% of the prescription dose while minimizing dose to lung, heart, and skin. Statistical analyses were performed between critical organ doses and patient anatomic features, i.e., central lung distance (CLD), maximal heart distance (MHD), maximal heart length (MHL) and breast separation (BS). Results: Comparing to 3DCRT plans, on the average, eComp treatment planning process was about 7 minutes longer, but resulted in lower lung V20Gy, lower mean skin dose, with similar heart dose. The benefits were more pronounced for larger breast patients. To keep the lung V20Gy lower than 20% and mean skin dose lower than 85% of the prescription dose, eComp was the preferred method for patients with more than 2.3 cm CLD or larger than 22.5 cm BS. Conclusion: The study results may be useful in providing a handy criterion in clinical practice allowing us to easily choose between different planning techniques to satisfy the planning goal with minimal increase in complexity and cost.

Radiological conditions at Bikini Atoll: Prospects for resettlement

International Nuclear Information System (INIS)

1998-01-01

An international Advisory Group met at IAEA Headquarters in Vienna on 11-15 December 1995 for the purpose of reviewing the current radiological conditions at Bikini Atoll, Republic of the Marshall Islands, and advising on the prospects for rehabilitation of the atoll and resettlement of its indigenous population. The Advisory Group was convened by the IAEA in response to a request for technical assistance from the Government of the Marshall Islands within the framework of IAEA technical co-operation project MHL/9/003, 'Radiological Monitoring in Bikini Atoll'. The primary aim of this review was to assist the Bikinian people to form their own judgement on the radiological conditions at their atoll and on the prospects for resettling there, should they so desire. At the meeting, the Advisory Group benefited greatly from the participation of a delegation from the Marshall Islands. At the request of the Government of the Marshall Islands, the international review was limited to Bikini Atoll and did not extend to other atolls, islands and isles affected by radioactive fallout from the testing. Moreover, within Bikini Atoll, it was concentrated on Bikini Island, where the Bikinian population formerly resided. The review relates to the prevailing radiological circumstances and their implications for the future habitability of the atoll. It is not intended to include the retrospective assessment of the past radiological impact of nuclear testing. The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) has routinely estimated, and reported to the United Nations General Assembly, radiation levels and effects attributable to nuclear weapon testing, including the tests carried out in the territory of the Marshall Islands. Some of the UNSCEAR estimates have been included in the report, but only for the sake of completeness

Es un tumor benigno de baja prevalencia que compromete solo el 0,1% de los tumores y quistes de los maxilares, con una muy baja tendencia a la recidiva; es común en pacientes jóvenes, generalmente mujeres, de mayor presentación en el maxilar superior, asintomático, de crecimiento lento y poco invasivo; el cual se puede semejarse a otras lesiones odontogénicas de mayor agresividad como el quiste dentígero y el ameloblastoma, entre otros benignos como el odontoma complejo y adenomas pleomórficos. A menudo se observa como una lesión radiolúcida de aspecto quístico unilocular, asociada a órganos dentales incluidos, usualmente dientes caninos. Su localización clásica nos orienta al diagnóstico y su patrón histológico ductiforme (apariencia basaloide con estructuras glanduliformes, calcificaciones esferulares y presencia de abundante material amiloide que facilitan su reconocimiento microscópico es muy propio de esta lesión tumoral. Se presenta un caso de un paciente de 12 años de edad, asintomática y asimétrica facial, de sexo femenino, con un diagnóstico definitivo por biopsia de TOA en la región anterior del maxilar superior asociado a un órgano dental 23 incluido; intervenido quirúrgicamente, colocando material de injerto como sustituto óseo, teniendo en cuenta estado general del paciente, diagnósticos diferenciales, características radiográficas, tomográficas y clínicas.

Investigation of heavy quark and multiple interactions at HERA

International Nuclear Information System (INIS)

Magro, L.M.

2005-09-01

This thesis is oriented to the study of heavy quark photoproduction and multiple interactions, MI. For this reason we search for D* Mesons, in order to tag the charm quark, and we restrict ourselves in the region: Q 2 2 . For the theoretical calculations we use two Monte Carlo event generators: RAPGAP 3.1 and PYTHIA 6.2. Heavy quark production provides a large hard scale and therefore a small α s , which allows to test the perturbative QCD theory. On the other hand, MI has been proven to be important in hadron-hadron collisions. In this thesis, using MC event generators, we search for possible signals of MI in heavy quark production in electron-proton, ep, collisions. The thesis begins with a Theoretical Overview, with an introduction to ep collisions physics and the heavy quark photoproduction. We also give an introduction to the MI model included in PYTHIA. The next chapter introduces the concept of jet and presents some methods for the Heavy Quark Identification. After these two theoretical chapters there is a study of the direct and photon resolved processes, as well as the parton showering with RAPGAP. Since this thesis is oriented to the study of MI, PYTHIA plays a very important role because it includes a MI model also for ep collisions. Therefore, the fourth chapter is oriented to study the different steps in the event generation in PYTHIA. Chapter 7 is a D* Meson photoproduction study, where we include a comparison between the data, taken from the PhD Thesis of Gero Flucke. Finally, chapter 8 is a search for possible signals on MI. In hadron-hadron collisions it is clear that MI play a role. In ep collisions it is not so clear although MI could play a role in resolved photon events. The aim of this chapter is to find signals where HERA measurements could be sensitive to MI. (orig.)

Metal complexes of Schiff base derived from 2-thiophene carboxaldehyde and 2-aminobenzoic acid (HL) are reported and characterized based on elemental analyses, IR, 1H NMR, solid reflectance, magnetic moment, molar conductance and thermal analysis (TGA). The ligand dissociation as well as the metal-ligand stability constants were calculated pH metrically at 25 °C and ionic strength μ = 0.1 (1 M NaCl). The complexes are found to have the formulae [M(HL) 2](X) n· yH 2O (where M = Fe(III) (X = Cl, n = 3, y = 3), Co(II) (X = Cl, n = 2, y = 1.5), Ni(II) (X = Cl, n = 2, y = 1) and UO 2(II) (X = NO 3, n = 2, y = 0)) and [M(L) 2] (where M = Cu(II) (X = Cl) and Zn(II) (X = AcO)). The molar conductance data reveal that Fe(III) and Co(II), Ni(II) and UO 2(II) chelates are ionic in nature and are of the type 3:1 and 2:1 electrolytes, respectively, while Cu(II) and Zn(II) complexes are non-electrolytes. IR spectra show that HL is coordinated to the metal ions in a terdentate manner with ONS donor sites of the carboxylate O, azomethine N and thiophene S. From the magnetic and solid reflectance spectra, it is found that the geometrical structure of these complexes are octahedral. The thermal behaviour of these chelates shows that the hydrated complexes losses water molecules of hydration in the first step followed immediately by decomposition of the anions and ligand molecules in the subsequent steps. The activation thermodynamic parameters, such as, E*, Δ H*, Δ S* and Δ G* are calculated from the DrTG curves using Coats-Redfern method. The synthesized ligands, in comparison to their metal complexes also were screened for their antibacterial activity against bacterial species, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus pyogones and Fungi (Candida). The activity data show that the metal complexes to be more potent/antibacterial than the parent Schiff base ligand against one or more bacterial species.

O presente trabalho teve como objetivo descrever as alterações morfológicas de ovários fetais equinos ocorrentes durante o desenvolvimento gestacional. Foram utilizados fetos equinos provenientes de abatedouro. Imediatamente após o abate foi realizada medição da distância cefalococcígea para o cálculo da idade gestacional em dias (dias de gestação - DG e dissecação dos fetos para a retirada e fixação dos ovários. Foram realizadas avaliações macroscópicas e histológicas pelas técnicas de Hematoxilina-eosina e PAS. Foram utilizados 19 fetos com idade de 50-269 dias de gestação, distribuídos em 9 grupos de DG. Na avaliação macroscópica foi observada diferença entre o volume dos ovários de acordo com a idade gestacional, sendo observado maior volume ovariano entre os dias 210 a 269 de desenvolvimento gestacional. Na avaliação histológica foi observado epitélio de revestimento cúbico e distinção entre as camadas cortical e medular nos ovários fetais a partir de 50-89 DG. As principais características identificadas foram à distinção morfológica entre as camadas cortical e medular nos ovários fetais equinos: os cordões ovígeros surgiram no intervalo de 150-179 DG; o córtex iniciada como uma camada delgada e por volta do 210º dia de gestação apresentou espessamento pelo aumento da quantidade de tecido conjuntivo rico em vasos sanguíneos, o qual se manteve até os estágios finais da gestação; a região medular adquiriu uniformidade estrutural por volta do 150º dia, mostrando células similares em tamanho e vasos sanguíneos de calibre maior. A partir desta etapa, as células medulares

Influence of electronic and steric effects on stability constants and electrochemical reversibility of divalent ion complexes with glycine and sarcosine

Cd II complexes with glycine (gly) and sarcosine (sar) were studied by glass electrode potentiometry, direct current polarography, virtual potentiometry, and molecular modelling. The electrochemically reversible Cd II -glycine-OH labile system was best described by a model consisting of M(HL), ML, ML 2 , ML 3 , ML(OH) and ML 2 (OH) (M = Cd II , L = gly) with the overall stability constants, as log β, determined to be 10.30 ± 0.05, 4.21 ± 0.03, 7.30 ± 0.05, 9.84 ± 0.04, 8.9 ± 0.1, and 10.75 ± 0.10, respectively. In case of the electrochemically quasi-reversible Cd II -sarcosine-OH labile system, only ML, ML 2 and ML 3 (M = Cd II , L = sar) were found and their stability constants, as log β, were determined to be 3.80 ± 0.03, 6.91 ± 0.07, and 8.9 ± 0.4, respectively. Stability constants for the ML complexes, the prime focus of this work, were thus established with an uncertainty smaller than 0.05 log units. The observed departure from electrochemical reversibility for the Cd-sarcosine-OH system was attributed mainly to the decrease in the transfer coefficient α. The MM2 force field, supplemented by additional parameters, reproduced the reported crystal structures of diaqua-bis(glycinato-O,N)nickel(II) and fac-tri(glycinato)-nickelate(II) very well. These parameters were used to predict structures of all possible isomers of (i) [Ni(H 2 O) 4 (gly)] + and [Ni(H 2 O) 4 (sar)] + ; and (ii) [Ni(H 2 O) 3 (IDA)] and [Ni(H 2 O) 3 (MIDA)] (IDA = iminodiacetic acid, MIDA = N-methyl iminodiacetic acid) by molecular mechanics/simulated annealing methods. The change in strain energy, ΔU str , that accompanies the substitution of one ligand by another (ML + L' → ML' + L), was computed and a strain energy ΔU str = +0.28 kcal mol -1 for the reaction [Ni(H 2 O) 4 (gly)] + + sar → [Ni(H 2 O) 4 (sar)] + + gly was found. This predicts the monoglycine complex to be marginally more stable. By contrast, for the reaction [Ni(H 2 O) 3 IDA] + MIDA → [Ni(H 2 O) 3 MIDA] + IDA

The former included the following electronic resources: SOMED (SM78, Cochrane Library – Central (CCTR93, MEDLINE Alert (ME0A, MEDLINE (ME95, CATFILEplus (CATLINE (CA66, ETHMED (ED93, GeroLit (GE79, HECLINET (HN69, AMED (CB85, CAB Abstracts (CV72, GLOBAL Health (AZ72, IPA (IA70, Elsevier BIOBASE (EB94, BIOSIS Previews (BA93, EMBASE (EM95, EMBASE Alert (EA08, SciSearch (IS90, Cochrane Library – CDSR (CDSR93, NHS-CRD-DARE (CDAR94, NHS-CRD-HTA (INAHTA as well as NHSEED (NHSEED. The present report includes German and English literature published until 31.08.2005. The search parameters can be found in the appendix. No limits were placed on the target population. The methodological quality of the included clinical studies was assessed using the criteria recommended by the “Scottish Intercollegiate Guidelines Network Grading Review Group“. Economic studies were evaluated by the criteria of the German Scientific Working Group Technology Assessment for Health Care. Results: The literature search identified 17 relevant medical publications. One of these studies compared laparoscopic and conventional surgery with and without mesh for incisional hernia repair, while 16 studies compared laparoscopic and conventional surgery with mesh for incisional hernia repair. Among these studies were 14 primary studies (one randomised controlled trial (RCT, two systematic reviews and one HTA-Report. The only study comparing laparoscopic and conventional surgery without mesh found substantial differences in terms of baseline characteristics between treatment groups. The outcome parameters showed decreased recurrence rates for the laparoscopic repair and similar safety of the procedures. Studies comparing laparoscopic and conventional surgery with mesh found similar outcome in terms of medical efficacy and safety. However, there was a trend towards lower recurrence rates, length of hospital stay, and postoperative

à quelque Bradyodonte primitif. Les Actinoptérygiens ne sont représentés que par quelques écailles isolées, du Dévonien terminal, et qui évoquent le genre Moythomasia Les restes de Vertébrés les plus abondants dans les nodules du Dévonien de Bolivie sont d'étranges éléments osseux en forme de flûte de Pan qui sont ici attribués au genre Zamponiopteron n.g. Ces éléments, qui n'ont jamais été signalés ailleurs qu'en Bolivie, peuvent être interprétés comme des nageoires paires ankylosées de quelque Chondrichthyen inconnu Trois espèces ont été reconnues dans ce genre, mais elles correspondent seulement à des types morphologiques et il n'y a aucune certitude quant à leur appartenance à des espèces biologiques différentes. Toute conclusion générale d'ordre paléobiogéographique concernant cette faune serait prématurée Cependant, on doit noter qu'elle comprend un mélange de formes à vaste répartition (Rhénanides, quelques Acanthodiens, Actinoptérygiens de type Moythomasia, des formes dont les affinités sont transpacifiques (Acanthodiens proches de Sinacanthus et des formes peut-être endémiques (Pucapampella, Zamponiopteron. Se describen restos de Vertebrados silúricos y devónicos en varias localidades de Bolivia La mayor parte de los especimenes se conservan en concreciones fosfáticas procedentes del Devónico del Altiplano y de la región subandina Algunos especímenes aislados se encontraron en areniscas o lutitas. Los 'Agnathos' se conocen sólo por unas escamas de Thelodontes del final del Silúrico o Devónico inferior de Seripona, Chuquisaca. Todos los demás restos de Vertebrados se atribuyen a Gnathostomos, en particular a Acanthodios, Placodermos, Chondrichthyos y Actinopterygios. Los Acanthodios son representados por algunos huesos dentígeros de mandíbulas de Ischnacanthidos y por espinas y cinturones pectorales de Climatiidos. Son relativamente abundantes y casi no difieren de los restos de Acanthodios conocidos

and ESO Garching . The HARPS consortium has been granted 100 observing nights per year during a 5-year period at the ESO 3.6-m telescope to perform what promises to be the most ambitious systematic search for exoplanets so far implemented worldwide . The project team is directed by Michel Mayor (Principal Investigator), Didier Queloz (Mission Scientist), Francesco Pepe (Project Managers Consortium) and Gero Rupprecht (ESO representative).
