Assessment of personal care and medical robots from older adults' perspective
Demographic reports indicate that population of older adults is growing significantly over the world and in particular in developed nations. Consequently, there are a noticeable number of demands for certain services such as health-care systems and assistive medical robots and devices. In today's world, different types of robots play substantial roles specifically in medical sector to facilitate human life, especially older adults. Assistive medical robots and devices are created in various designs to fulfill specific needs of older adults. Though medical robots are utilized widely by senior citizens, it is dramatic to find out into what extent assistive robots satisfy their needs and expectations. This paper reviews various assessments of assistive medical robots from older adults' perspectives with the purpose of identifying senior citizen's needs, expectations, and preferences. On the other hand, these kinds of assessments inform robot designers, developers, and programmers to come up with robots fulfilling elderly's needs while improving their life quality

Regulation of BAG-1 IRES-mediated translation following chemotoxic stress
There are three major isoforms of BAG-1 in mammalian cells, termed BAG-1L (p50), BAG-1M (p46) and BAG-1S (p36) that function as pro-survival proteins and are associated with tumorigenesis and chemoresistance. Initiation of BAG-1 protein synthesis can occur by both cap-dependent and cap-independent mechanisms and it has been shown that synthesis of BAG-1S is dependent upon the presence of an internal ribosome entry segment (IRES) in the 5'-UTR of BAG-1 mRNA. We have shown previously that BAG-1 IRES-meditated initiation of translation requires two trans-acting factors poly (rC) binding protein 1 (PCBP1) and polypyrimidine tract binding protein (PTB) for function. The former protein allows BAG-1 IRES RNA to attain a structure that permits binding of the ribosome, while the latter protein appears to be involved in ribosome recruitment. Here, we show that the BAG-1 IRES maintains synthesis of BAG-1 protein following exposure of cells to the chemotoxic drug vincristine but not to cisplatin and that this is brought about, in part, by the relocalization of PTB and PCBP1 from the nucleus to the cytoplasm
Improving inter-observer variability in the evaluation of ultrasonographic features of polycystic ovaries
<p>Abstract</p> <p>Background</p> <p>We recently reported poor inter-observer agreement in identifying and quantifying individual ultrasonographic features of polycystic ovaries. Our objective was to determine the effect of a training workshop on reducing inter-observer variation in the ultrasonographic evaluation of polycystic ovaries.</p> <p>Methods</p> <p>Transvaginal ultrasound recordings from thirty women with polycystic ovary syndrome (PCOS) were evaluated by three radiologists and three reproductive endocrinologists both before and after an ultrasound workshop. The following endpoints were assessed: 1) follicle number per ovary (FNPO), 2) follicle number per single cross-section (FNPS), 3) largest follicle diameter, 4) ovarian volume, 5) follicle distribution pattern and 6) presence of a corpus luteum (CL). Lin's concordance correlation coefficients (rho) and kappa statistics for multiple raters (kappa) were used to assess level of inter-observer agreement (>0.80 good, 0.60 – 0.80 moderate/fair, <0.60 poor).</p> <p>Results</p> <p>Following the workshop, inter-observer agreement improved for the evaluation of FNPS (rho = 0.70, delta rho = +0.11), largest follicle diameter (rho = 0.77, delta rho = +0.10), ovarian volume (rho = 0.84, delta rho = +0.12), follicle distribution pattern (kappa = 0.80, delta kappa = +0.21) and presence of a CL (kappa = 0.87, delta kappa = +0.05). No improvement was evident for FNPO (rho = 0.54, delta rho = -0.01). Both radiologists and reproductive endocrinologists demonstrated improvement in scores (p < 0.001).</p> <p>Conclusion</p> <p>Reliability in evaluating ultrasonographic features of polycystic ovaries can be significantly improved following participation in a training workshop. If ultrasonographic evidence of polycystic ovaries is to be used as an objective measure in the diagnosis of PCOS, then standardized training modules should be implemented to unify the approach to evaluating polycystic ovarian morphology.</p
