N-methylnicotinamide as marker for biological methylation in humans

Rosemann, G.M. (Gertruida Magdalena) 10 March 2006 (has links)
The purpose of this study was to determine whether the methylation of nicotinamide to N-methylnicotinamide could discriminate between differences in methionine nutritional status, and by implication methylation capacity, in healthy humans. As part of this thesis, a highly selective high performance liquid chromatography (HPLC) method for the determination of N-methylnicotinamide (NMN) in urine and plasma was developed and validated. Quantification was by fluorescence detection of the 1,6-naphthyridine derivatives, formed after incubation of NMN with acetophenone in alkaline conditions. Seven volunteers participated in a trial to evaluate the ability of a nicotinamide load test to discriminate between changes in the methylation status of the individual. The methylation status was measured as the time dependent changes in plasma NMN concentrations after a nicotinamide load. A basal nicotinamide load test was performed on each individual. The methylation status was then changed, by means of a methionine load, and the nicotinamide load test was repeated during the enhanced methylation state. The dynamic changes in N-methylnicotinamide levels indicated that the methionine load changed neither the plasma NMN concentrations, nor the rates of NMN formation. The conclusion of this study was that nicotinamide loading could not be used as a dynamic function test to assess biological methylation in healthy humans. / Dissertation (MSc (Chemical Pathology))--University of Pretoria, 2006. / Chemical Pathology / unrestricted

Transformation adaptation: developing a framework for donor organisation support of climate change adaptation in resource poor communities

Dada, Rehana January 2015 (has links)
Poor communities already face severe challenges in meeting their basic needs, whether because of poor income opportunities, inadequate service delivery, or degraded ecosystems that can no longer support the needs of people. Non profit organisations who provide support for development are also challenged by financial restrictions and social and political structures that prevent or limit project development. Climate change is understood to have the most severe impact on the most vulnerable communities and sectors of communities by reducing the availability and accessibility of basic resources such as water, food and energy, impacting severely on human health and wellbeing, and further reducing the capacity of ecosystems to support livelihoods. This will add a layer of significant new complications to the ability of poor communities to maintain or improve standards of living, and further challenge non profit organisations that support such communitiesAnticipatory adaptation to climate change can reduce some of the impacts of climate change, and also address some key development stresses. This thesis aims to provide a framework that is relevant for supporting adaptation to climate change within the context of resource poor communities in a developing country. Non profit organisations and donor agencies could support success and autonomy in adaptation processes by making provision for locally defined understanding of adaptation, and locally determined processes and programmes. This can be taken further into implementation of programming that addresses local short term development priorities alongside, or as part of long term adaptation work. The research followed a number of steps involving a multitude of techniques including literature review, interviews, a survey, consultation with an expert group, further consultation with stakeholders, and a final electronic review. Its outcome is a strategy that can be used to support climate change adaptation in resource poor communities. A definition for adaptation is proposed as an interpretation of adaptation that is relevant in this context. The intended end goal of adaptation as defined in this research is a better form of development that : supports a harmonious and respectful relationship between humans and their natural resource base; averts further destructive global change or at the very least prevents it from becoming unmanageable; and manages the impacts of past and ongoing destructive change so that there is lowest possible loss of natural, human, or cultural resources. The term transformative adaptation emerged from the research processes to describe adaptation to climate change that concurrently addresses development challenges, is grounded in community development aspirations, integrates programming work across multiple thematic areas and approaches, and addresses the causes of climate change within adaptation interventions. The following broad guidelines are used to inform programming within the framework of transformative adaptation : Human communities are faced with an enormous challenge resulting from global change and sociopolitical injustices; Well planned anticipatory adaptation can limit exposure and vulnerability to at least some of the projected impacts of climate change; Adaptation to climate change incorporates a reduction of vulnerability to underlying development stresses, alongside a reduction of vulnerability to specific climate change stresses; Existing development work forms the foundation for adaptation interventions, acknowledging the interdependence of social, natural and economic systems and the need to maintain their health; Adaptation decision making is community based, and acknowledges that resource poor communities are best placed to establish their own development needs, drive implementation of interventions in own spaces, and identify own limits to adaptation; Adaptation work incorporates mitigation objectives so that the causes of climate change are addressed as part of the strategy for coping with climate change; Adaptation programming acknowledges the strong interlinkages between, and integrates work across, the thematic areas of water security, food sovereignty, energy security, land security, human wellbeing and livelihood diversity; Adaptation uses a broad set of approaches that spans research, knowledge sharing, advocacy, and investment in technology and infrastructure; There is flexibility in project design and implementation to allow room for experimentation with new concepts, and also to change design as knowledge, understanding, and geophysical, biophysical and sociopolitical conditions change.

Pilates for postural stability in computer users

Strydom, Lana January 2008 (has links)
The impact of computer use is evident in every day life (Harrington, Carter, Birrell and Gompertz, 2000:264). Lind (2002:18) explains that global trends continue to show that the most severe work-related health problems that exist amongst computer users are musculoskeletal disorders. As technology has lead to increases in automation, so it has lead to increases in work-related illnesses. Although studies have explored the effects of ergonomics (Thibodeau, 1995:322) in static working positions there has been little evidence supporting a solution in overcoming poor occupational postures. Many health practitioners argue that occupationally caused, or aggravated, musculoskeletal disorders are steadily increasing. Thus, even though computers have improved productivity and made work easier for the population in general, they have adverse effects as well. Designing the proper tools or a setup of the work place is of prime importance for the elimination of chronic diseases attributed to sedentary lifestyles. Regular physical activity had long been regarded as an important component of a healthy lifestyle. This notion has recently been reinforced by scientific evidence linking regular physical activity with a wide array of physical and mental health benefits, synonymous with an improvement in wellness (Pratt, Macera, and Wang, 2000:63). According to Pratt et al. (2000:63) higher direct medical costs associates with physical inactivity. Further cross-sectional epidemiologic studies and controlled experimental investigations conducted by Okura, Nakata and Tanaka (2003:1131) had demonstrated that physically active adults, in contrast to their sedentary counterparts, tend to develop and maintain higher levels of physical fitness. These studies had not only demonstrated the positive results of physical activity, such as an improvement in blood lipid profile, body composition, glucose tolerance and insulin sensitivity, but had also shown that participation in such activity decreased the risk of developing several chronic hypokinetic diseases, including coronary heart disease (CHD), hypertension, non-insulin dependant diabetes mellitus (type II), osteoporosis, colon cancer, anxiety and depression. In addition, low levels of habitual physical activity and the subsequent low levels of physical fitness were associated with a marked increase in all-cause mortality rates. Okura et al. (2003:1131) confirm that effects of exercise intensity on physical fitness and risk factors for coronary Herat disease.

Perception of cognitive distance : effects of physical environment on the perception

Murata, Kazuyjuki January 1975 (has links)
The lack of knowledge concerning the relationships between the physical environment and people's behavior was discussed in relation to the inadequacy of today's architectural programming. Possible applications of man-environment studies were suggested. Nature of the environmental information was analyzed, and a term 'cognitive distance' was defined. Essential variables that affect the construction of the mental map and the perception of distance were derived primarily from previous studies. The city of Vancouver was analyzed utilizing methods originated by K. Lynch, and a survey was conducted in the city to examine relations between the various variables and the perception of distance. The type of the distance examined was 'inward (toward downtown)’, 'ego-centric', and urban scale(4 mile) 'cognitive distance'. Results: Following four variables seemed to have effects on the perception of distance; sex, age, mode of transportation, and the score on 'Thing-orientation scale'. Male tended to be more accurate in their estimations (or to estimate the particular distance of 4 mile as being shifter) than female Ss. Ss aged over 20, or car drivers, or Ss with higher T-scores were also more accurate than younger Ss, or bus riders or car passengers, or Ss with lower T-scores, respectively. Concerning the possible effects on perception by physical variables, our results were unclear mainly due to the differing characteristics of the Ss at the four locations. Implications of results were discussed. / Applied Science, Faculty of / Architecture and Landscape Architecture (SALA), School of / Graduate

Die mens as faktor in suksesvolle organisasie : 'n persoonlike en professionele leierskapsperspektief

Brewis, Frans Mattheus 26 March 2012 (has links)
M.Phil. / The success of organisations has traditionally been measured based on profits and contribution to shareholders funds. However, recent literature indicates that the human factor has become a key element in achieving success. Widely described as soft issues, these human factors potentially have a profound effect on the success of the organisation (Business Report, 7 November 1999:6). The aim of this study was to icentify which soft issues were prevalent within the organisation, and also to determine what influence these soft issues have on the success of the organisation. The focus was thus on the phenomenon of soft issues within the organisation. In order to realise this aim, it was required to do research to establish which human factors are described in recent literature in order to establish their VI influence on the success of an organisation. Chapter two dealt with this aim and the research revealed a whole spectrum of soft issues including values, emotional intelligence, ethics and many more (See Table 1, Page 28) The research indicated that emotional intelligence and values were regarded as having a profound effect on the success of the organisation. Chapter three analised these two concepts in more detail with specific focus on the origin and nature of emotional intelligence and values as well as their effect on the success of the organisation. The study was motivated by the quest to find the co-ordination between the soft issues found within the organisation and the influence it had on the success of the organisation. The study was done from the paradigm of personal and professional leadership which has as main trait, the believe that change should happen from within the individual, and not from the outside (Covey, 1992:42).
