Abstract
The objective of the present study was to determine effects of strain of Holstein-Friesian and feed system on body weight (BW) and body condition score (BCS; scale of 1 to 5) lactation profiles in seasonal-calving, grass-based milk production systems. The 3 strains of Holstein-Friesian compared differed in milk production potential and were high-production North American (HP), high-durability North American (HD), and New Zealand (NZ). The 3 feed systems compared were a high grass allowance feed system typical of spring-calving herds in Ireland (MP); an increased stocking rate system (HS); and an increased concentrate supplementation system (HC), each maintained within a separate farmlet. The data comprised 20,611 weekly BW and 7,920 BCS records assessed every 3 wk across 5 yr on 584 lactations. An exponential function was used to model BW and BCS lactation profiles across feed systems. Across feed systems, the NZ strain was significantly lighter (545 kg) but had greater average BCS (3.10 units) compared with the HP (579.3 kg and 2.76 units, respectively) and HD strains (583.2 kg and 2.87 units, respectively). Across feeding systems, the HD and HP strains exhibited a greater loss of BCS in early lactation (0.27 and 0.29 units, respectively) compared with the NZ strain (0.21 units). The HP strain failed to gain BCS over the entire lactation. Concentrate input did not affect the rate of BCS or BW loss in early lactation or BCS at 60 DIM. This study extends previous research outlining the greater suitability of the NZ strain to the low-cost grass-based system of milk production predominantly operated in Ireland.

Abstract
The objective of this paper was to compare the economic efficiency of 3 divergent strains of Holstein-Friesian cows--high-production North American (HP), high-durability North American (HD), and New Zealand (NZ)--across a variety of Irish pasture-based production systems: Moorepark (MP), high concentrate (HC), and high stocking rate (HS). Physical performance data were obtained from a 5-yr study conducted previously. The economic performance of each strain and feed system was derived for 3 production scenarios: European Union (EU) milk quota applied at the farm level using predicted future prices and costs (S1); EU milk quota applied at the industry level, thus permitting quota leasing at predicted future prices and costs (S2); and EU milk quota applied at the industry level with a limitation on land availability (S3). The economic results showed that in a fixed milk quota scenario, the NZ strain in the MP and HS feed systems returned the highest profitability. The HD strain in the MP and HS feed systems proved the next most profitable, whereas the HP animals were least profitable in all feed systems. Similar to S1, in S2 the NZ were most profitable; however, the difference between the MP and HS was much smaller. The HP strain proved least profitable in all feed systems. In S3, the NZ strain was again most profitable; however, within that scenario the HS feed system was optimal. These results show that exclusive genetic selection for increased milk production results in reduced farm profitability because the productivity gains achieved are outweighed by associated increases in reproductive wastage costs in a pasture-based system. These results reinforce the economic value of genetic improvement based on a selection index encompassing traits of economic significance pertinent to the production environment.

Abstract
There are many initiatives in Europe trying to refine the exposure assessment for food packaging migrants. In the USA, the US Food and Drug Administration (US FDA) uses food consumption and food-type distribution factors to aid the exposure assessment process and generate more realistic estimates of exposure. The present study developed food-consumption factors and food-type distribution factors for Irish children aged 5-12 years from data collected as part of a National Children's Food Survey (NCFS) completed in Ireland in 2003-04, combined with data from the 2003-05 Irish Food Packaging Database and from literature data on surface area-to-weight ratios for food packaging. Consumption factors are defined as the fraction of a person's diet likely to contact a specific food-contact material, while food-type distribution factors reflect the fraction of all food contacting each material that is aqueous, acidic, alcoholic or fatty. In this study, it was found that 'total plastics' had the highest consumption factor of 0.83, while 'total paper and board' had a factor of 0.13 and 'total metal and alloys' had a factor of 0.06. Although it is tentative to compare the US FDA factors with the factors derived in the current study, as the US FDA data are for the total US population, the consumption factor for 'total plastics' in the present study (0.83) was similar to that used by the US FDA (0.79). However, a large difference existed for the consumption factor for 'total metal and alloys' in the Irish data (0.06) and the US FDA data (0.2). In terms of the type of materials used for foods, glass was used mainly for acidic foods (0.67), while plastic was uniformly used for all food types. The food-contact area for plastic packaging for all foods consumed by children was 10.67 dm2/child day(-1), which is slightly lower than the proposed value for the average European consumer of 12.4 dm2/person day(-1). However, this should be expected, as children do not consume as much food as adults. When scenario exposure estimates were made, it was found that when using European Union assumptions, estimates were much larger than when using consumption factors and food-type distribution factors in the exposure assessment, even when conservative assumptions were employed for the consumption factor. This study highlights the potential use of consumption factors and food-type distribution factors in the refinement of the exposure assessment process and how these factors can be calculated using data collected as part of a national food survey.

Abstract
Radiation therapy has been used in the treatment of a wide variety of cancers for nearly a century and is one of the most effective ways to treat cancer. Low-dose ionizing radiation (IR) can interfere with cell division of cancer and normal cells by introducing oxidative stress and injury to DNA. The differences in the response to IR-induced DNA damage and increased reactive oxygen species between normal human fibroblasts (NHFs) and cancerous SHSY-5Y cells were considered. H2AX staining and comet assays revealed that NHF cells responded by initiating a DNA repair sequence whereas SHSY-5Y cells did not. In addition, NHF cells appeared to quench the oxidative stress induced by IR, and after 24 h no DNA damage was present. SHSY-5Y cells, however, did not repair their DNA, did not quench the oxidative stress, and showed characteristic signs that they were beginning to undergo apoptosis. These results indicate that there is a differential response between this cancerous and normal cell line in their ability to respond to low-dose IR, and these differences need to be exploited in order to treat cancer effectively. Further study is needed in order to elucidate the mechanism by which SHSY-5Y cells undergo apoptosis following radiation and why these normal cells are better equipped to deal with IR-induced double-strand breaks and oxidative stress.

Abstract
OBJECTIVE The emergence of a new generation of "point-and-shoot" digital cameras offers doctors a compact, portable and user-friendly solution to the recording of highly detailed digital photographs and video images. This work highlights the use of such technology, and provides information for those who wish to record, store and display their own medical images. METHODS Over a 3-month period, a digital camera was carried by a doctor in a busy, adult emergency department and used to record a range of clinical images that were subsequently transferred to a computer database. RESULTS In total, 493 digital images were recorded, of which 428 were photographs and 65 were video clips. These were successfully used for teaching purposes, publications and patient records. CONCLUSIONS This study highlights the importance of informed consent, the selection of a suitable package of digital technology and the role of basic photographic technique in developing a successful digital database in a busy clinical environment.

Abstract
In the European Union (EU), many assumptions are employed to calculate the intake of migrating chemicals from food packaging. However, very little is known about the actual intake of packaged food, the type of this food and the type of packaging used for this food. The objective of the current study was to examine intakes of packaged food in children aged 5-12 years to provide information on the types of food that are packaged and the type of packaging used. To do this, a food-consumption database, which also recorded information on packaging, was merged with a packaging database, which provided information on the contact layers of packaging. Foods were classified into EU Food categories according to European Council Directive EC 85/575/EEC (European Council 1985), which determined their food type (i.e. aqueous, acidic, alcoholic and fatty). The mean daily intake of all packaged food was 1195 g day-1 with an upper intake of 1959 g day-1 (97.5th percentile); the intake of food packaged in plastic was 993 g day-1 with an upper percentile of 1692 g day-1 (97.5th percentile). The mean daily intake of fat from all packaged food was 62 g day-1, with an upper intake of 100 g day-1 (97.5th percentile). When this was investigated further, it was found that the mean fat intake from packaged 'fatty' foods only was 32 g day-1, with an upper intake of 61 g day-1 (97.5th percentile). The food that contributed most to fat intake was milk. As many food chemical intake assessments are moving towards probabilistic methods, probabilities of a food being packaged and the probability of the type of packaging used were determined. The probability of food being packaged was 0.88. Some foods not 100% packaged included fruit, vegetables, liquid beverages non-alcoholic (includes water) and bread. Probabilities were also derived for the packaging types used for food. It can be concluded that not all the individual assumptions used in the EU exposure assessment are conservative, but in combination they are conservative.

Abstract
Neuronal cells depend on mitochondrial oxidative phosphorylation for most of their energy needs and therefore are at a particular risk for oxidative stress. Mitochondria play an important role in energy production and oxidative stress-induced apoptosis. In the present study, we have demonstrated that external oxidative stress induces mitochondrial dysfunction leading to increased ROS generation and ultimately apoptotic cell death in neuronal cells. Furthermore, we have investigated the role of Coenzyme Q10 as a neuroprotective agent. Coenzyme Q10 is a component of the mitochondrial respiratory chain and a potent anti-oxidant. Our results indicate that total cellular ROS generation was inhibited by Coenzyme Q10. Further, pre-treatment with Coenzyme Q10 maintained mitochondrial membrane potential during oxidative stress and reduced the amount of mitochondrial ROS generation. Our study suggests that water-soluble Coenzyme Q10 acts by stabilizing the mitochondrial membrane when neuronal cells are subjected to oxidative stress. Therefore, Coenzyme Q10 has the potential to be used as a therapeutic intervention for neurodegenerative diseases.

Abstract
Neuronal cell death induced by oxidative stress is correlated with numerous neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and stroke. The causes of sporadic forms of age-related neurodegenerative diseases are still unknown. Recently, a correlation between paraquat exposure and neurodegenerative diseases has been observed. Paraquat, a nonselective herbicide, was once widely used in North America and is still routinely used in Taiwan. We have used differentiated Human Neuroblastoma (SHSY-5Y) cells as an in vitro model to study the mechanism of cell death induced by paraquat. We observed that paraquat-induced oxidative stress in differentiated SHSY-5Y cells as indicated by an increase in the production of cellular reactive oxygen species (ROS). Furthermore, apoptosis was evident as indicated by cellular and nuclear morphology and DNA fragmentation. Interestingly, pretreatment of SHSY-5Y cells with water-soluble Coenzyme Q10 (CoQ10) before paraquat exposure inhibited ROS generation. Pretreatment with CoQ10 also significantly reduced the number of apoptotic cells and DNA fragmentation. We also analyzed the effect of paraquat and CoQ10 on isolated mitochondria. Our results indicated that treatment with paraquat induced the generation of ROS from isolated mitochondria and depolarization of the inner mitochondrial membrane. Pretreatment with CoQ10 was able to inhibit ROS generation from isolated mitochondria as well as the collapse of mitochondrial membrane potential. Our results indicate that water-soluble CoQ10 can prevent oxidative stress and neuronal damage induced by paraquat and therefore, can be used for the prevention and therapy of neurodegenerative diseases caused by environmental toxins.

Abstract
BACKGROUND The role of long-term glycaemic control in minimizing long-term complications of diabetes mellitus is evidence-based and national guidelines recommend a target glycosylated haemoglobin level of approximately 7%. Although the role of self-monitoring blood and urine glucose is less well defined, this activity consumes vast National Health Service (NHS) resources. AIMS The aims of this study were to (i) determine the current practice of glucose self-monitoring in primary care, (ii) determine any changes to therapy made as a result and (iii) compare monitoring and frequency of monitoring in those patients using insulin with those patients taking oral hypoglycaemic agents. METHODS Postal questionnaire to 311 patients using insulin or oral hypoglycaemic agents identified from three general practices. RESULTS The response rate was 59.8% (186/311), with the majority of responding patients (n = 158, 87.3%) performing self-monitoring. The patients using insulin were more likely to be self-monitoring than those taking oral therapy (chi(2), P < 0.001, d.f. = 1). The majority of patients who self-monitored and were using insulin (n = 45, 61.1%) altered the dose of insulin if a reading was beyond their target range. However, the majority of patients who self-monitored and were taking oral therapy (n = 48, 68.6%) took no action at all. CONCLUSIONS Blood glucose self-monitoring was common in those treated with insulin or oral hypoglycaemics, although those using insulin were more likely to self-monitor. Notably many patients, particularly those on oral therapy, took no action based on the results of self-monitoring.

Abstract
OBJECTIVE To evaluate habitual levels of physical activity in a nationally representative sample of adults in Ireland. DESIGN Cross-sectional survey using a self-administered questionnaire. Usual levels of work, recreational and household activities were evaluated in relation to anthropometric, demographic and socio-economic characteristics. The amount and intensity of all activities were quantified by assigning metabolic equivalents (METS) to each activity. SETTING Republic of Ireland and Northern Ireland, 1997-1999. SUBJECTS Random sample of 1379 adults aged 18-64 years. RESULTS Men were approximately twice as active in work and recreational activity (139.7 +/- 83.9 METS) as women (68.5 +/- 49.8 METS; P<0.001) but women were three times more active in household tasks (65.9 +/- 58.7 METS vs. 22.6 +/- 24.6 METS; P<0.001). Overall levels of physical activity declined with increasing age, particularly leisure activity in men. In women the decline in work activity was offset by spending more time in household pursuits. Twenty-five per cent of the subjects were extremely overweight (body mass index (BMI>28 kg m(-2)) or obese (BMI >30 kg m (-2)). Fewer obese subjects reported higher levels of work and leisure activities. However, a higher percentage of obese women reported participation in the higher levels of household activities. Participation rates in recreational activities were low. Walking was the most important leisure activity of both men (41%) and women (60%). In terms of hours per week spent in vigorous physical activity, men were more active than women, professional and skilled non-manual women were more active than women in other social classes, and younger subjects (aged 18-35 years) were more active than older subjects. CONCLUSIONS The holistic approach used in the assessment of physical activity in this study has revealed important and subtle differences in the activity patterns of men and women. Failure to fully characterise the respective activity patterns of men and women could lead to ill-informed public health policy aimed at promoting and sustaining lifetime habits of physical activity. The results suggest that simple population-focused programmes to promote physical activity are unlikely to offer the same chance of long-term success as more sensitive and individualised strategies.

Abstract
This international study investigates factors underlying international variations in rates of youth drug use among representative samples of 15-year-olds in five cities (Bremen, n = 871; Dublin, n = 983; Groningen, n = 487; Newcastle upon Tyne, n = 880; Rome, n = 666). It reveals a higher level of drug use in English-speaking compared to continental populations. Drug use was associated with peer, family and individual factors. Logistic regression showed that family structure and sport were associated with lower rates and delinquent behaviour with higher rates of drug use in all cities and among males and females. Among males, city of residence also independently predicted drug use. The effect of traditional families and studiousness in reducing drug use was most evident for male drug use in low-use cities: higher rates of use in English-speaking cities appear partially due to the drug use of low-risk males.
