There is currently great interest in the potential use of carbon nanotubes as delivery vessels for nanotherapeutics and other medical applications. However, no data are available on the effects of sterilization methods on the properties of nanotube dispersions, the form in which most medical applications will be processed. Here we show the effects of gamma irradiation from a 60Co source on the dispersion and optical properties of single-wall carbon nanotubes in aqueous dispersion. Samples of different length-refined populations were sealed in ampoules and exposed to a dose of approximately 28 kGy, a level sufficient to ensure sterility of the dispersions. In contrast to literature results for solid-phase nanotube samples, the effects of gamma irradiation on the dispersion and optical properties of the nanotube samples were found to be minimal. Based on these results, gamma irradiation appears sufficiently non-destructive to be industrially useful for the sterilization of nanotube dispersions.

Healthcare overuse is the provision of care in which the benefits do not j.stify the harms and/or costs. Overuse literature is poorly categorized thus impeding research, practice, and policy to reduce overuse and improve healthcare quality. We developed an overuse taxonomy and searched for and reviewed the healthcare overuse literature in an attempt to better understand and categorize research on overuse practice and patterns. We found that more than two-thirds of articles were observational （70%）, the most prevalent purpose of overuse was treatment/secondary prevention （69%）, the most common type of overuse was overtreatment （73 %）, drivers of and methods to reduce overuse were each discussed in about 40% of abstracts, and the most frequently mentioned clinical area was pharmacy. A high volume of overuse literature exists. However, the maj.rity of overuse research is observational, descriptive, and focuses on overtreatment and overprescribing rather than methods to reduce overuse. Some overuse is not labelled as such. Our taxonomy adequately organized the existing literature and identified areas where additional research efforts are most needed. A common taxonomy, such as ours, could help researchers categorize their work, assist clinicians and policymakers in identifying and implementing findings, and guide future research to improve healthcare quality.

Biodiversity is thought to be essential for ecosystem stability, function and long-term sustainability. Since nitrogen is the limiting nutrient for plant growth in many terrestrial ecosystems, reactive nitrogen has the potential to reduce the diversity of terrestrial vegetation and associated biota through favouring species adapted to quickly exploiting available nutrients. Although the potential has long been recognised, only recently has enough evidence come together to show beyond reasonable doubt that these changes are already occurring. Linked together, experimental, regional/empirical, and time-series research provide a powerful argument that enhanced deposition of reactive nitrogen across great Britain, and potentially the rest of Europe, has resulted in a significant and ongoing decline in grassland species richness and diversity.

This study provides information on the development and factor scaling, validity, and reliability of a newly developed community service utilization measure (Older Adult Service Usage Assessment-OASUA). Analyzes indicate the OASUA can be used to assess current perceived community service use and satisfaction, as well as providing an indication for future service use and potential service needs with older persons. Additional data collection sites should be identified and a broader sample obtained so as to confirm the psychometric properties of the instrument in conj.nction with further development of the OASUA.

AIM To evaluate recent trends in gastric cancer incidence, response to treatment, and overall survival among Alaska Native(AN) people. METHODS A retrospective analysis of the Alaska Native Medical Center patient database was performed. Patient history, clinical, pathological, response to treatment and patient outcomes were collected from one-hundred and thirty-two AN gastric cancer patients. The Surveillance, Epidemiology and End Result database 18 was used to collect comparison United States non-Hispanic White(NHW) and AN gastric cancer patient data between *** AN gastric cancer patients have a higher incidence rate, a poorer overall survival, and are diagnosed at a significantly younger age compared to NHW patients. AN patients differ from NHW patients in greater prevalence of non-cardia, diffuse subtype, and signet ring cell carcinomas. AN females were more likely to be diagnosed with later stage cancer, stage IV, compared to AN males. Diminished overall survival was observed among AN patients with increasing stage, O+ blood type, er in AN people with outcome *** Our findings confirm the importance of early detection, treatment, and surgical resection for optimizing AN patient outcomes. Further research on early detection markers are warranted.

Go to virtually any conference or symposium on insect pests and so called ＂Integrated Pest Management,＂ or IPM, is presented as the answer to all management problems. IPM is the textbook paradigm （e.g., Kogan, 1998; Pedigo, 2002; Pedigo ＆ Rice, 2009） that guides all aspects of insect pest management research and implementation （Zalucki et al., 2009）. In most cases the way IPM is put in to practice, as opposed to the textbook j.rgon could, somewhat cynically, be regarded as ＂incidental＂ to pesticide management. How did it come to this？

The bioremediation of a long-term contaminated soil through biostimulation and surfactant addition was evaluated. The concentrations of 1,1,1-trichloro-2,2-bis（4-chlorophenyl）ethane（DDT） and its metabolites 1,1-dichloro-2,2-bis（4-chlorophenyl） ethane（DDD） and1,1-dichloro-2,2-bis（4-chlorophenyl） ethylene（DDE） were monitored during an 8-week remediation process. Physicochemical characterization of the treated soil was performed before and after the bioremediation process. The isolation and identification of predominant microorganisms during the remediation process were also carried out. The efficiency of detoxification was evaluated after each bioremediation protocol. Humidity and p H and the heterotrophic microorganism count were monitored weekly. The DDT concentration was reduced by 79% after 8 weeks via biostimulation with surfactant addition（B ＋ S） and 94.3%via biostimulation alone（B）. Likewise, the concentrations of the metabolites DDE and DDD were reduced to levels below the quantification limits. The microorganisms isolated during bioremediation were identified as Bacillus thuringiensis, Flavobacterium sp., Cuprivadius sp.,Variovorax soli, Phenylobacterium sp. and Lysobacter sp., among others. Analysis with scanning electron microscopy（SEM） allowed visualization of the colonization patterns of soil particles. The toxicity of the soil before and after bioremediation was evaluated using Vibrio fischeri as a bioluminescent sensor. A decrease in the toxic potential of the soil was verified by the increase of the concentration/effect relationship EC50 to 26.9% and 27.2% for B ＋ S and B, respectively, compared to 0.4% obtained for the soil before treatment and 2.5%by natural attenuation after 8 weeks of treatment.
