Exposure to indoor background radiation and urinary concentrations of 8-hydroxydeoxyguanosine, a marker of oxidative DNA damage. (1/20)

We investigated whether exposure to indoor [gamma]-radiation and radon might be associated with enough free radical formation to increase urinary concentrations of 8-hydroxydeoxyguanosine (8-OHdG), a sensitive marker of DNA damage, due to a hydroxyl radical attack at the C8 of guanine. Indoor radon and [gamma]-radiation levels were measured in 32 dwellings for 6 months by solid-state nuclear track detectors and thermoluminescent dosimeters, respectively. Urine samples for 8-OHdG determinations were obtained from 63 healthy adult subjects living in the measured dwellings. An overall tendency toward increasing levels of 8-OHdG with increasing levels of radon and [gamma]-radiation was seen in the females, presumably due to their estimated longer occupancy in the dwellings measured. Different models were considered for females, with the steepest slopes obtained for [gamma]-radiation with a coefficient of 0.500 (log nmol/l of 8-OHdG for each unit increase of [gamma]-radiation on a log scale) (p<0.01), and increasing to 0.632 (p = 0.035), but with larger variance, when radon was included in the model. In conclusion, there seems to be an effect of indoor radioactivity on the urinary excretion of 8-OHdG for females, who are estimated to have a higher occupancy in the dwellings measured than for males, for whom occupational and other agents may also influence 8-OHdG excretion. ree radicals; [gamma]-radiation; radon.  (+info)

Cancer risk around the nuclear power plants of Trillo and Zorita (Spain). (2/20)

AIM: To investigate the association between cancer risk and proximity of place of residence to the Guadalajara nuclear power plants: Trillo and Zorita. METHODS: Case-control study. Cases were patients admitted with cancer and controls were non-tumorous patients, both admitted to Guadalajara Hospital (period 1988-99). Exposure factor: place of residence (areas within 10, 20, and 30 km of each plant). Odds ratios (ORs) of those areas closest to the plants were calculated with respect to those furthest away; a linear trend analysis was also performed. RESULTS: In the extreme areas in the vicinity of Trillo, an OR of 1.71 was obtained (95% CI 1.15 to 2.53), increasing in magnitude in the subgroup of more radioinducible tumours and in the period considered as post-latency (1997-99). Risk increased linearly with proximity to the two plants, significantly in Trillo (p < 0.01) but not in Zorita (p = 0.19). CONCLUSIONS: There is an association between proximity of residence to Trillo and cancer risk, although the limitations of the study should be kept in mind when interpreting the possible causal relation.  (+info)


The current status of radiation protection in Canada is discussed in the last of a three-part series. Particular emphasis has been placed on the role of the Radiation Protection Division of the Department of National Health and Welfare. A radioactive fallout study program has been established involving the systematic collection of air and precipitation samples from 24 locations, soil samples from 23 locations, fresh-milk samples from 16 locations, wheat samples from nine areas and human-bone specimens from various hospitals throughout Canada. A whole-body-counting facility and a special study of fallout in Northern areas have also been initiated. For any age group, the highest average strontium-90 concentration in human bone so far reported has been less than four picocuries per gram of calcium compared with the maximum permissible level of 67 derived from the International Committee on Radiation Protection (ICRP) recommendations. By the end of 1963 a general downward trend of levels of radioactivity detected in other parts of the program has been observed. Programs to assess the contribution to the radiation exposure of members of the population from medical x-rays, nuclear reactor operations and natural background-radiation sources have also been described. The annual genetically significant dose from diagnostic x-ray examinations in Canadian public hospitals has been estimated to be 25.8 mrem. Results from the reactor-environment monitoring programs have not suggested the presence of radioactivity beyond that contributed from fallout.  (+info)

Radon in homes and risk of lung cancer: collaborative analysis of individual data from 13 European case-control studies. (4/20)

OBJECTIVE: To determine the risk of lung cancer associated with exposure at home to the radioactive disintegration products of naturally occurring radon gas. DESIGN: Collaborative analysis of individual data from 13 case-control studies of residential radon and lung cancer. SETTING: Nine European countries. SUBJECTS: 7148 cases of lung cancer and 14,208 controls. MAIN OUTCOME MEASURES: Relative risks of lung cancer and radon gas concentrations in homes inhabited during the previous 5-34 years measured in becquerels (radon disintegrations per second) per cubic metre (Bq/m3) of household air. RESULTS: The mean measured radon concentration in homes of people in the control group was 97 Bq/m3, with 11% measuring > 200 and 4% measuring > 400 Bq/m3. For cases of lung cancer the mean concentration was 104 Bq/m3. The risk of lung cancer increased by 8.4% (95% confidence interval 3.0% to 15.8%) per 100 Bq/m3 increase in measured radon (P = 0.0007). This corresponds to an increase of 16% (5% to 31%) per 100 Bq/m3 increase in usual radon--that is, after correction for the dilution caused by random uncertainties in measuring radon concentrations. The dose-response relation seemed to be linear with no threshold and remained significant (P = 0.04) in analyses limited to individuals from homes with measured radon < 200 Bq/m3. The proportionate excess risk did not differ significantly with study, age, sex, or smoking. In the absence of other causes of death, the absolute risks of lung cancer by age 75 years at usual radon concentrations of 0, 100, and 400 Bq/m3 would be about 0.4%, 0.5%, and 0.7%, respectively, for lifelong non-smokers, and about 25 times greater (10%, 12%, and 16%) for cigarette smokers. CONCLUSIONS: Collectively, though not separately, these studies show appreciable hazards from residential radon, particularly for smokers and recent ex-smokers, and indicate that it is responsible for about 2% of all deaths from cancer in Europe.  (+info)

Archeo-cell biology: carbon dating is not just for pots and dinosaurs. (5/20)

Defining the life span of specific human cell populations is limited by our inability to mark the exact time when cells are born in a way that can be detected over many years. In this issue of Cell, Spalding et al. (2005) describe a clever strategy for retrospectively birth dating human cells in vivo, based on their incorporation of 14C during a peak in atmospheric levels of this isotope resulting from above-ground nuclear arms testing in the 1950s.  (+info)

Indoor radon and lung cancer. Estimating the risks. (6/20)

Radon is ubiquitous in indoor environments. Epidemiologic studies of underground miners with exposure to radon and experimental evidence have established that radon causes lung cancer. The finding that this naturally occurring carcinogen is present in the air of homes and other buildings has raised concern about the lung cancer risk to the general population from radon. I review current approaches for assessing the risk of indoor radon, emphasizing the extrapolation of the risks for miners to the general population. Although uncertainties are inherent in this risk assessment, the present evidence warrants identifying homes that have unacceptably high concentrations.  (+info)

Indoor-atmospheric radon-related radioactivity affected by a change of ventilation strategy. (7/20)

The present author has kept observation for concentrations of atmospheric radon, radon progeny and thoron progeny for several years at the campus of Fukushima Medical University. Accidentally, in the midst of an observation term, i.e., February 2005, the facility management group of the university changed a strategy for the manner of ventilation, probably because of a recession: (I) tidy everyday ventilation of 7:30-24:00 into (II) shortened weekday ventilation of 8: 00-21 : 00 with weekend halts. This change of ventilation manner brought a clear alteration for the concentrations of radon-related natural radioactivity in indoor air. The present paper concerns an investigation of the effect of the ventilation strategy on the indoor-atmospheric radon-related radioactivity.  (+info)

Indoor radon concentrations and assessment of doses in four districts of the Punjab Province - Pakistan. (8/20)

Seasonal indoor radon measurement studies have been carried out in four districts, namely, Jhelum, Chakwal, Rawalpindi and Attock of the Punjab Province. In this regard, CR-39 based detectors were installed in bedrooms, drawing rooms and kitchens of 40 randomly selected houses in each district. After exposing to radon in each season, CR-39 detectors were etched in 6M NaOH at 80 degrees C and counted under an optical microscope. Indoor radon activity concentrations in the houses surveyed ranged from 15 +/- 4 to 176 +/- 7 Bq m(-3) with an overall average value of 55 +/- 31 Bq m(-3). The observed annual average values are greater than the world average of 40 Bq m(-3). Maximum indoor radon concentration levels were observed in winter season whereas minimum levels were observed in summer season. None of the measured radon concentration value exceeded the action level of 200-400 Bq m(-3). The season/annual ratios for different type of dwellings varied from 0.87 +/- 0.93 to 1.14 +/- 1.10. The mean annual estimated effective dose received by the residents of the studied area was found to be 1.39 +/- 0.78 mSv. The annual estimated effective dose is less than the recommended action level (3-10 mSv).  (+info)

That is likely to be the case as its higher profile service to Delhi and Dubai will not affect its performance until 2016 given the Nov-2015 planned route launches. Those markets will be watched closely as it puts the mission profile of the 787-9 and Air Canadas long-haul calculations to the test. Air Canada is undertaking a lot of network jockeying in 2015 as it also works to attain ambitious cuts in its unit costs of 15% (using 2012 as a baseline). The key for Air Canada is to maintain its recent positive momentum while working to achieve maximum network utility in the face of a familiar and fierce competitor. ...

Final Environmental Impact Statement, Environmental Radiation Protection Requirements for Normal Operations of Activities in the Uranium Fuel Cycle, p. 18.). Before the transfer of environmental radiation responsibilities from the AEC to the EPA, and until the EPA issued the new rule in 1977, the annual radiation dose limit for a member of the general public from nuclear fuel cycle operations was 5 mSv-20 times higher than the EPAs limit.. The AEC had conservatively assigned a limit of 1/10th of the 50 mSv/year applied to occupational radiation workers, which it had, in turn, conservatively chosen to provide a high level of worker protection from the potential negative health effects of atomic radiation.. The AECs occupational limit of 50 mSv was less than 1/10th of the previously applied tolerance dose of 2 mSv/day, which worked out to an annual limit of approximately 700 mSv/year. That daily limit recognized the observed effect that damage resulting from radiation doses was routinely ...

X-rays are an important diagnostic tool in dentistry because of their ability to penetrate and pass through body tissues. Because they penetrate at different speeds depending on tissue density (shorter and thus darker on exposed film for soft tissues, longer and lighter for hard tissues like bone or teeth), were able to detect decay which appear as dark areas on x-ray film.. Without x-rays, the early detection and diagnosis of dental problems would be quite difficult. But despite its obvious benefits, its still a form of released energy that exposes patients to a certain amount of radiation. Since the potential health risk from radiation depends on the amount released (the dosage) and for how long and often a person is exposed, we must determine if the dosage and frequency from dental x-rays is a cause for concern.. Its a common misconception to view any radiation exposure as dangerous. The truth is, however, were all exposed daily to radiation from the natural environment - about 2 to 4.5 ...
FRAMES 1.7/GENII 2.10 replaces GENII 2.09, which has been distributed by RSICC. The GENII system includes capabilities for calculating radiation doses following chronic and acute releases. Radionuclide transport via air, water, or biological activity may be considered. Air transport options include both puff and plume models, each allowing use of an effective stack height or calculation of plume rise from buoyant or momentum effects (or both). Building wake effects can be included in acute atmospheric release scenarios. The code provides risk estimates for health effects to individuals or populations; these can be obtained using the code by applying appropriate risk factors to the effective dose equivalent or organ dose. In addition, GENII Version 2 uses cancer risk factors from Federal Guidance Report 13 to estimate risk to specific organs or tissues. Although the codes were initially developed at Hanford, they were designed with the flexibility to accommodate input parameters for a wide ...

I too have been unable to sleep in an Air Canada lie flat bed, even after being sleep deprived. I was flying from Winnipeg (YWG) through Toronto (YYZ) with an overnight stay, and then on to Heathrow (LHR), when our flight from YWG to YYZ was delayed 6 hours due to heavy snow in YYZ. After spending 6 hours in the YWG lounge (I was 35K status at the time) with my family avoiding some of the other guests who were drinking heavily from the self-service bar, I was very pleasantly surprised when were upgraded to business class for the flight to Toronto. We were less happy when the seriously drunk guest from the lounge was also seated in business class. I was waiting for the flight attendant to come back to me in the last business class row so I could tell her of the other passengers recent history when she disappeared. Then 2 police officers arrived to ask the drunk guest to leave. After a small amount of mild verbal resistance he left the plane without much of a scene. The flight attendant returned, ...

Patients admitted to the intensive care unit (ICU) are at risk for acquisition of healthcare associated infections. These infections are often anticipated by overgrowth of potentially pathogenic micro-organisms (PPMO). Several decontamination strategies aim to prevent overgrowth of these PPMO in the respiratory tract, gastro-intestinal tract or both. These include selective decontamination using antibiotics (SDD and SOD) and chlorhexidine mouthwash (CHX). This thesis aims to determine the effects of different decontamination strategies on patient outcomes and the occurrence of antibiotic resistant bacteria in European Intensive Care Units (ICU) with low and higher prevalence of antibiotic resistance. Several research questions have been answered for ICUs with low levels of antibiotic resistance, using data from high-quality registries (MARS-cohort, NICE-registry) and in an individual participant data meta-analysis (IPD-MA) of randomized studies. The main study underlying this thesis is a new cluster

Air Canada Center Seating Map for When infected with HIV, CD+ cells still replicate in response to pathogens, but the replicated CD+ cells are infected with the virus, are unable to activate their target B and T cells, and eventually die. Initially, the non-infected CD+ cells still provide an effective response against pathogens. However, over time, proliferation of infected CD+ cells in response to pathogens results in an increase in infected CD+ cells in circulation. These will eventually die, but before doing so may bind with healthy CD+ cells, resulting in their death. In addition, the immune system may recognise the virus-laden cells as invasive, and begin to attack its own CD+ cells. Together, these processes result in a gradual reduction in the number of circulating CD+ cells, reducing the immune systems ability to defend itself effectively against viruses, bacteria and some cancers. When the CD+ cell count falls below /mm, approximately half the immune system reserve has been destroyed. ...

My research interests include Bacterial Cell Cycle Regulation and Signal Transduction mechanisms.. 1. Bacterial Cell Cycle Regulation- Epigenetic mechanisms regulating various physiological activities in the prokaryotic cells are increasingly being appreciated. Methylation of specific bases of the DNA molecule by methyltransferases is the most common epigenetic modification observed in the bacterial cells. This modification of nucleotides adds another level of regulation at the transcription; furthermore, it has a fundamental role in the cell physiological processes such as DNA replication, DNA mismatch repair, and virulence mechanisms in many pathogens. Among the prokaryotic DNA methyltransferases, Dam expressed among the Gammaproteobacteria is the most intensively studied. In contrast to Dam, another DNA methyltransferase CcrM (Cell Cycle Regulated Methylase) has been described in the Alphaproteobacteria, where it plays an important role in the cell cycle regulation of Caulobacter crescentus ...
In West Africa, encouraging sustainable production intensification is one of the regions main challenges in agriculture. Poor yields often result from a lack of knowledge of soil management, which has led to sub-optimal cultivation methods, choice of poor quality seeds and highly toxic pesticides. These factors have contributed to a decline in environmental quality and human well-being, through unnecessary costs of synthetic, toxic contamination of food-chains and disruption of ecosystem services. Monitoring of human and environmental health is a critical element in any functional agricultural system, but these elements are most often missing in developing countries. The IPPM programme endeavours to help farmers reverse these negative factors ...

BACKGROUND It has been reported that there are great deal of changes in the epidemiology of hepatitis A at the present. The epidemiologic studies regarding to hepatitis A virus (HAV) infection are not sufficient both in the country and study region. OBJECTIVE To investigate HAV seroprevalence and association with socio-demographic variables. DESIGN Cross-sectional and community based study. SETTING Erzurum Province, Eastern Turkey between April and June 1998. SUBJECTS Four hundred and fifty persons under the age of 30 years. RESULTS The rate of the study involvement was 87.1% (392 persons) and ratio for seropositivity 84.2%. Although seropositivity is elevated by age, it has been high within the younger age group. Epidemiological changes could not be interpreted, since the study results were first for the group of people aged under 30 years. Statistical significance was found between hepatitis A seroprevalence and age, the number of households and localisation of toilet within the house. There

Not all obese subjects have an adverse metabolic profile predisposing them to developing type 2 diabetes or cardiovascular disease. The BioSHaRE-EU Healthy Obese Project aims to gain insights into the consequences of (healthy) obesity using data on risk factors and phenotypes across several large-scale cohort studies. Aim of this study was to describe the prevalence of obesity, metabolic syndrome (MetS) and metabolically healthy obesity (MHO) in ten participating studies. Ten different cohorts in seven countries were combined, using data transformed into a harmonized format. All participants were of European origin, with age 18-80 years. They had participated in a clinical examination for anthropometric and blood pressure measurements. Blood samples had been drawn for analysis of lipids and glucose. Presence of MetS was assessed in those with obesity (BMI ≥ 30 kg/m2) based on the 2001 NCEP ATP III criteria, as well as an adapted set of less strict criteria. MHO was defined as obesity, having none of
