To argue for the use of mixed methods when researching communities.

Although research involving minority communities is now advanced, not enough effort has been made to formulate methodological linkages between qualitative and quantitative methods in most studies. For instance, the quantitative approaches used by epidemiologists and others in examining the wellbeing of communities are usually empirical. While the rationale for this is sound, quantitative findings can be expanded with data from in-depth qualitative approaches, such as interviews or observations, which are likely to provide insights into the experiences of people in those communities and their relationships with their wellbeing.

Academic databases including The Cochrane Library, MEDLINE, CINAHL, AMED, INTERNURSE, Science Direct, Web of Knowledge and PubMed.

An iterative process of identifying eligible literature was carried out by comprehensively searching electronic databases.

Using mixed-methods approaches is likely to address any potential drawbacks of individual methods by exploiting the strengths of each at the various stages of research. Combining methods can provide additional ways of looking at a complex problem and improve the understanding of a community's experiences. However, it is important for researchers to use the different methods interactively during their research.

The use of qualitative and quantitative methods is likely to enrich our understanding of the interrelationship between wellbeing and the experiences of communities. This should help researchers to explore socio-cultural factors and experiences of health and healthcare practice more effectively.

To explain a strategy to improve response rates from healthcare professionals to a postal survey in the Republic of Ireland.

Response rates to surveys conducted among healthcare professionals have been declining steadily. This paper is based on the development of a response rate strategy to address this challenge.

A study in Ireland using a survey instrument that relied on the voluntary participation of managers and healthcare professionals.

Database and manual literature searches were undertaken across the literature related to methodology to increase response rates from healthcare professionals. The databases Cinahl, Medline, PsycINFO, Wiley Online Library and Scopus-V.4 were searched using 'response rates' and the terms 'response rate theory', 'survey response rates', 'increase', 'improve health professionals', 'primary care research', 'health care teams', 'health service research' and 'research participation'. Only English-language publications were reviewed.

Researchers must be aware of factors that influence healthcare professionals they seek to engage and so they can create research environments that do not preclude or dissuade practitioners from participating.

The potential impact of poor response rates is a concern for healthcare researchers. Research-based practice is central to improving the quality of health care. Response-rate strategies can enhance research.

Nurse researchers as part of the broader health research community need to consider potential response rates at the research design stage. Response rate strategies should be developed and outlined as part of their overall research proposal and study reports.

The glycation of Ribonuclease A (RNase A) at pH 7.4 and 37 °C with ribose, glucose and fructose has been monitored by UV-vis, fluorescence, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and matrix assisted laser desorption ionization spectroscopy-time of flight (MALDI-TOF) methods. The enzymatic activity and DNA binding ability of glycated RNase A was also investigated by an agarose gel-based assay. A precipitation assay examined the ribonucleolytic activity of the glycated enzyme. An increase in incubation time resulted in the formation of high molecular weight AGEs with a decrease in ribonucleolytic activity. Ribose exhibits the highest potency as a glycating agent and showed the greatest reduction in the ribonucleolytic activity of the enzyme. Interestingly, glycated RNase A was unable to bind with the ribonuclease inhibitor (RI) and DNA. The glycated form of the protein was also found to be ineffective in DNA melting unlike native RNase A.Prothrombin is activated to thrombin by the prothrombinase complex through sequential cleavage at two distinct sites. This occurs at sites of vascular injury in a highly regulated cascade of serine protease and cofactor activation, where activated platelets provide a suitable surface for protease/cofactor/substrate assembly. The precise structural and conformational changes undergone during the transition from prothrombin to thrombin have been studied for decades, and several structures of prothrombin fragments along the activation pathway have been solved. Here we present a new structure analyzed in context of other recent structures and biochemical studies. What emerges is an unexpected mechanism that involves a change in the mode of binding of the F2 domain (fragment 2) on the catalytic domain after cleavage at Arg320, and a subsequent reorientation of the linker between the F2 and catalytic domain to present the Arg271 site for cleavage.Over the past two decades, advances in genetic technologies have posed unexpected challenges to the ethical and legal framework guiding the application of the most recent advances in healthcare technologies. By and large, these challenges have been successfully met by the introduction by statutes such as the Genetic Information Nondiscrimination Act (GINA). However, over the past several years, these advances in the ability to measure genetic (or heritable) contributions to medical illness have been joined by advances in epigenetic (or acquired) contributions to common medical illnesses. Unfortunately, the moral and legal framework for the use of these epigenetic technologies, which can objectively determine the presence of medical illnesses such as diabetes or the consumption of substances of abuse, is not as well developed. This communication provides an introduction to the fundamentals of epigenetics and then reviews how some of the latest advances in this technology can now be used to assess the consumption of alcohol and tobacco. Next, the possible mechanisms through which these tools could be employed clinically are discussed. Finally, the authors outline the potential for misuse of this technology and suggest that well-informed policy could play a critical role in shaping the optimal implementation of epigenetic technologies.
Both endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and endoscopic retrograde cholangiopancreatography (ERCP) cytology may provide tissue diagnoses in solid pancreatic neoplasms. However, there are scant data comparing these two methods. This study aims at retrospectively comparing EUS-FNA and ERCP tissue sampling and ability of cytopathological diagnosis in solid pancreatic neoplasms and to determine usefulness and adverse events of combining both procedures.

Two hundred and thirty four patients suspected to have solid pancreatic mass on abdominal ultrasound and/or computed tomography (CT) were enrolled. EUS-FNA (group A), ERCP cytology (group B) and combined procedures (Group C) performed in 105, 91 and 38 cases, respectively.

Sensitivity, specificity and accuracy were 98.9%, 93.3% and 98.1% for group A, and 72.1%, 60% and 71.4% for group B. Those for group C were all 100%. Sensitivity for malignancy in the pancreas head was 100% for group A and 82.4% for group B, and in the pancreas body and tail, 97.6% for group A and 57.1% for group B. EUS-FNA was more sensitive than ERCP cytology in diagnosing malignant pancreatic neoplasms 21-30 mm in size (p = 0.0068), 31-40 mm (p = 0.028) and ≥ 41 mm (p < 0.0001). Sensitivity for pancreatic malignancy with group C was 100% regardless of mass location or size. Adverse events were 1.9%, 6.6% and 2.6% following EUS-FNA, ERCP and combined procedures, respectively.

EUS-FNA is superior to ERCP cytology for diagnosis of solid pancreatic neoplasms. Although combination of both procedures provide efficient tissue diagnosis and with a minimal adverse events rate, a prospective study including larger number of patients is required.

Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors.Over the past decade, there have been substantial improvements in our knowledge of pancreatic neoplasms and their precursor lesions. Extensive genetic analyses, recently using high-throughput molecular techniques and next-generation sequencing methodologies, and the development of sophisticated genetically engineered mouse models closely recapitulating human disease, have improved our understanding of the genetic basis of pancreatic neoplasms. These advances are paving the way for refined, molecular-based classifications of pancreatic neoplasms with the potential to better predict prognosis and, possibly, response to therapy. Another major development resides in the identification of subsets of pancreatic exocrine and endocrine neoplasms which occur in the context of hereditary syndromes and whose genetic basis and tumor development have been at least partially defined. A-1331852 However, despite all molecular progress, correct and careful morphological characterization of tissue specimens both in the context of experimental and routine diagnostic pathology represents the basis for any further genetic investigation or clinical decision.
