Cre-mediated site-specific recombination has become an invaluable tool for manipulation of the murine genome. The ability to conditionally activate gene expression or to generate chromosomal alterations with this same tool would greatly enhance zebrafish genetics. This study demonstrates that the HSP70
Telemedicine is a technology-based alternative to traditional health care delivery. However, poor security measures in telemedicine services can have an adverse impact on the quality of care provided, regardless of the chronic condition being studied. We undertook a systematic review of 58 journal articles pertaining to telemedicine security. These articles were selected based on a keyword search on 14 relevant journals. The articles were coded to evaluate the methodology and to identify the key areas of research in security that are being reviewed. Seventy-six percent of the articles defined the security problem they were addressing, and only 47% formulated a research question pertaining to security. Sixty-one percent proposed a solution, and 20% of these tested the security solutions that they proposed. Prior research indicates inadequate reporting of methodology in telemedicine research. We found that to be true for security research as well. We also identified other issues such as using outdated security standards.
Although consumers completed tasks with greater independence using telecare supports, caution should be used when interpreting results due to the small number of participants. The potential for this technology certainly exists in supporting consumers in their own homes thus, suggestions for future investigations are provided.
We investigated the perceptions of people about the safety, security and privacy of a telecare monitoring system for adults with developmental disabilities living in residential settings. The telecare system was used by remote caregivers overnight, when staff were not present in the homes. We surveyed 127 people from different stakeholder groups in the state of Indiana. The people surveyed included those with knowledge or experience of telecare, and those without. The stakeholders were clients, their advocates, service provider administrators and independent case coordinators. The responses in each category for every group were positive except one: only 4 of the 11 telecare case coordinators agreed that the telecare system provided a secure environment. Overall, the telecare system was perceived to be as safe, secure and private as the conventional alternative of having staff in the home.
Increased interest in using zebrafish as a model organism has led to a resurgence of fin regeneration studies. This has allowed for the identification of a large number of gene families, including signaling molecules and transcription factors, which are expressed during regeneration. However, in cases where no specific inhibitor is available for the gene product of interest, determination of a functional role for these genes has been difficult. Here we demonstrate that in vivo electroporation of morpholino oligonucleotides is a feasible approach for protein knock-down during fin regeneration. Morpholino oligonucleotides against fgfr1 and msxb were utilized and knock-down of both proteins resulted in reduced fin outgrowth. Importantly, Fgfr1 knock-down phenocopied outgrowth inhibition obtained with an Fgfr1 inhibitor. Furthermore, this method provided direct evidence for a functional role for msxb in caudal fin regeneration. Finally, knock-down of Fgfr1, but not Msxb, affected the blastemal expression of msxc, suggesting this technique can be used to determine epistasis in genetic pathways affecting regeneration. Thus, this convenient reverse genetic approach allows researchers to quickly (1) assess the function of genes known to be expressed during fin regeneration, (2) screen genes for functional relevance during fin regeneration, and (3) assign genes to the molecular pathways underlying fin regeneration.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
