Selected AbstractsThe 12th International Symposium on ALS/MND: Scientific Advancements in Amyotrophic Lateral SclerosisBRAIN PATHOLOGY, Issue 4 2002Srikanth Ranganathan MS First page of article [source] Digital image analysis of plus disease in retinopathy of prematurityACTA OPHTHALMOLOGICA, Issue 4 2009Tariq Aslam Abstract. An accurate assessment of retinopathy of prematurity (ROP) is essential in ensuring correct and timely treatment of this potentially blinding condition. Current modes of assessment are based upon clinical grading by expert examination of retinal changes. However, this may be subjective, unreliable and difficult and there has been significant interest in alternative means of measurement. These have been made possible through technological advancements in image capture and analysis as well as progress in clinical research, highlighting the specific importance of plus disease in ROP. Progress in these two fields has highlighted the potential for digital image analysis of plus disease to be used as an objective, reliable and valid measurement of ROP. The potential for clinical and scientific advancement through this method is argued and demonstrated in this article. Along with the potential benefits, there are significant challenges such as in image capture, segmentation, measurement of vessel width and tortuosity; these are also addressed. After discussing and explaining the challenges involved, the research articles addressing digital image analysis of ROP are critically reviewed. Benefits and limitations of the currently published techniques for digital ROP assessment are discussed with particular reference to the validity and reliability of outcome measures. Finally, the general limitations of current methods of analysis are discussed and more diverse potential areas of development are discussed. [source] Label-free biochemical characterization of stem cells using vibrational spectroscopyJOURNAL OF BIOPHOTONICS, Issue 11 2009James W. Chan Abstract Raman and infrared (IR) spectroscopy are two complementary vibrational spectroscopic techniques that have experienced a tremendous growth in their use in biological and biomedical research. This is, in large part, due to their unique capability of providing label-free intrinsic chemical information of living biological samples at tissue, cellular, or sub-cellular resolutions. This article reviews recent developments in applying these techniques for the characterization of stem cells. A discussion of the potential for these methods to address some of the major challenges in stem cell research is presented, as well as the technological and scientific advancements that are needed to progress the knowledge in the field.

McDonald Abstract Social and cognitive characteristics of adults with intellectual disabilities (ID) place them at risk for inappropriate inclusion in or exclusion from research participation. As we grapple with how to include adults with ID in research in order to secure their right to contribute to scientific advancements and be positioned to derive benefit from ensuing knowledge, it is critical to consider scientific gatekeepers' perspectives on risks of and protections for including adults with ID in research. We surveyed 199 Institutional Review Board members and intellectual disability researchers in the United States to identify their perceptions of specific risks and necessary protections in (hypothetical) research studies. The research studies varied as to whether they included adults with ID in the research sample and the level of harm to which research participants were exposed. Results suggest that identification of psychological, social, and legal risks and necessary protections varied by the disability status of the sample, the level of risk, and the role of the person reviewing the study. For example, participants identified more psychological, information control, legal, and social risks in higher harm research studies. Participants reported a need for more protections in high-harm studies as well as studies that included adults with ID. In some instances the nature of identified risks and protections and respondents' characterization of these risks and necessary protections suggested concerns related specifically to adults with ID. Implications for practice, policy, and future research related to access to research participation are discussed. [source] The responsibility of the pharmaceutical industryCLINICAL MICROBIOLOGY AND INFECTION, Issue 2001C. Durrant The pharmaceutical industry plays an active role in policy surrounding the research, discovery and development of new medicines. Along with this commitment, the pharmaceutical industry must also take an active role in helping to ensure that appropriate patients receive access to state-of-the-art scientific advancements. The various players involved in drug development and introduction, including the pharmaceutical industry, clinicians, advocacy groups and regulatory bodies, need to work together to ensure patient access to quality care. While issues such as drug acquisition costs and marketing are often given a high profile, this may cloud perceptions of the industry's commitment to deliver important new medicines to the patients and healthcare systems that need them.
