Correlates of health and financial literacy in older adults without dementia
Jarred S Bennett, Patricia A Boyle, Bryan D James, David A Bennett
BMC Geriatrics , 2012, DOI: 10.1186/1471-2318-12-30
Abstract: We conducted a cross-sectional study using data from the Rush Memory and Aging Project, a community-based cohort study of aging in northeastern Illinois. The study consisted of 556 older persons without dementia, each determined by a clinical evaluation. Health and financial literacy were measured using a series of questions designed to assess the ability to understand and process health and financial information, concepts, and numeracy; the two scores were averaged to yield a total literacy score. Health promoting behaviors, including engagement in cognitive, physical, and social activities, were assessed using self report measures. Indicators of heath status, including cognition (global cognition and five specific cognitive abilities), functional status (basic and instrumental activities of daily living, mobility disability), and mental health (depressive symptoms, loneliness) were assessed.In a series of regression models adjusted for age, sex, and education, higher total literacy scores were associated with more frequent participation in health promoting behaviors, including cognitive, physical and social activities (all p values <0.05). Higher total literacy scores were associated with higher cognitive function, less disability, and better mental health (all p values?<?0.05). Literacy remained associated with health promoting behaviors and health status in fully adjusted models that also controlled for income and the number of chronic medical conditions. Most of the findings were similar for health and financial literacy except that health literacy was more strongly associated with health promoting behaviors whereas financial literacy was more strongly associated with mental health.Health and financial literacy are associated with more frequent engagement in health promoting behaviors and better health status in older persons without dementia.

Abstract: novations in gas permeable multifocal contact lenses Review (8578) Total Article Views Authors: Edward S Bennett Published Date September 2010 Volume 2010:2 Pages 85 - 90 DOI: http://dx.doi.org/10.2147/OPTO.S7021 Edward S Bennett College of Optometry, University of Missouri-St. Louis, St. Louis, MO 63121, USA Abstract: A current area of great consumer interest, as well as potential for practice growth, pertains to the contact lens correction of presbyopia. In particular many recent innovations with gas permeable multifocal lens designs have resulted in them comparing favorably – and often superiorly – to both soft multifocal lenses and monovision lenses, notably in the area of quality of vision. Gas permeable (GP) back surface aspheric multifocal designs have become increasingly popular because newer designs often are able to incorporate higher add powers than their predecessors, often via the addition of add power to the front surface of the lens. In addition, several front surface lens designs have recently been introduced which have the benefits of minimizing any corneal topography changes as they are typically fit in alignment with the cornea, while also providing a higher add than can be provided on the back surface of the lens. Some high specific gravity materials have been introduced which potentially allow for thinner lenses which have less mass and may exhibit more consistent centration than aspheric multifocal designs in conventional materials. New segmented, translating designs are available with the ability to provide an intermediate correction while the introduction of a hybrid design provides the practitioner with a viable option when a GP lens results in either poor centration of excessive subjective awareness.

Gene Therapy Strategies for HIV/AIDS: Preclinical Modeling in Humanized Mice
Michael S. Bennett,Ramesh Akkina
Viruses , 2013, DOI: 10.3390/v5123119
Abstract: In the absence of an effective vaccine and lack of a complete cure, gene therapy approaches to control HIV infection offer feasible alternatives. Due to the chronic nature of infection, a wide window of opportunity exists to gene modify the HIV susceptible cells that continuously arise from the bone marrow source. To evaluate promising gene therapy approaches that employ various anti-HIV therapeutic molecules, an ideal animal model is necessary to generate important efficacy and preclinical data. In this regard, the humanized mouse models that harbor human hematopoietic cells susceptible to HIV infection provide a suitable in vivo system. This review summarizes the currently used humanized mouse models and different anti-HIV molecules utilized for conferring HIV resistance. Humanized mouse models are compared for their utility in this context and provide perspectives for new directions.
H-alpha Objective Prism Survey of Abell 1060
S. M. Bennett,C. Moss
Physics , 1998, DOI: 10.1051/aas:1998358
Abstract: As part of a continuing study of the effect of cluster environment on the star formation properties of galaxies, we have undertaken an H-alpha objective prism survey of the nearby cluster, Abell 1060. We detect 33 galaxies in emission, 24 of which are cluster members. We present new radial velocity measurements and H-alpha+[NII] equivalent widths and fluxes for a number of these galaxies. We distinguish between galaxies with diffuse and compact emission, the latter having been associated in previous work with a disturbed morphology of the galaxy and most likely resulting from tidally-induced star formation from galaxy-galaxy or cluster-galaxy interactions. The fraction of cluster spirals in Abell 1060 detected with compact emission agrees with the expected fraction for a cluster of its richness, as derived from results of a previous survey of 8 clusters. Some of the detected cluster early-type spirals exhibit anomalously high global H-alpha equivalent widths, as compared to galaxies of similar type in the field.
Quantum nano-electromechanics with electrons, quasiparticles and Cooper pairs: effective bath descriptions and strong feedback effects
A. A. Clerk,S. Bennett
Physics , 2005, DOI: 10.1088/1367-2630/7/1/238
Abstract: Using a quantum noise approach, we discuss the physics of both normal metal and superconducting single electron transistors (SET) coupled to mechanical resonators. Particular attention is paid to the regime where transport occurs via incoherent Cooper-pair tunneling (either via the Josephson quasiparticle (JQP) or double Josephson quasiparticle (DJQP) process). We show that, surprisingly, the back-action of tunneling Cooper pairs (or superconducting quasiparticles) can be used to significantly cool the oscillator. We also discuss the physical origin of negative damping effects in this system, and how they can lead to a regime of strong electro-mechanical feedback, where despite a weak SET - oscillator coupling, the motion of the oscillator strongly effects the tunneling of the Cooper pairs. We show that in this regime, the oscillator is characterized by an energy-dependent effective temperature. Finally, we discuss the strong analogy between back-action effects of incoherent Cooper-pair tunneling and ponderomotive effects in an optical cavity with a moveable mirror; in our case, tunneling Cooper pairs play the role of the cavity photons.

Cholangiocarcinoma presenting as a solitary epididymal metastasis: a case report and review of the literature

Diagnostic Pathology , 2007, DOI: 10.1186/1746-1596-2-33
Abstract: A 72-year-old gentleman presented with a firm and tender mass involving the right epididymis. On examination, he was jaundiced. Computed tomography of the abdomen demonstrated an obstructive stricture of the extra-hepatic bile ducts, in keeping with a cholangiocarcinoma, through which a metal stent was endoscopically inserted for symptomatic relief.Subsequent right radical orchidectomy yielded a diffusely infiltrative adenocarcinoma obliterating the epididymis, extending into the rete testis, vas deferens and spermatic cord and showing widespread vascular and perineural invasion. Residual epididymal, rete, and testicular tubules showed no in situ neoplasia. Morphologically and immunohistochemically the features were in keeping with a metastasis from a primary cholangiocarcinoma.Only two cases of bile duct carcinoma metastasising to the male genital tract have previously been reported in the literature, the testis being the main site of metastasis in both cases. To our knowledge, this is the first described case of cholangiocarcinoma metastasising primarily to the epididymis, and presenting as a solitary epididymal metastasis in the absence of disseminated disease. It serves to highlight the importance of performing a thorough examination of the male external genitalia both clinically, in the follow up of cancer patients, and at autopsy.Solid tumor metastasis to the testis and paratesticular region is uncommon and principally encountered as an incidental autopsy finding [1]. Metastasis to the epididymis is relatively rare, fewer than fifty cases having been described in the published literature to date. The majority of such metastases are of prostatic origin and found incidentally at therapeutic orchidectomy [2]. We report a case of metastatic cholangiocarcinoma presenting as an epididymal mass; to our knowledge the first case described in the English literature.A 72-year-old gentleman presented with pain and swelling around the right testis. On admission, he was jau
Perturbation of Gravitational Lensing
Sun Hong Rhie,Clara S. Bennett
Physics , 2009,
Abstract: A gravitational lens system can be perturbed by "rogue systems" in angular proximities but at different distances. A point mass perturbed by another point mass can be considered as a large separation approximation of the double scattering two point mass (DSTP) lens. The resulting effective lens depends on whether the perturber is closer to or farther from the observer than the main lens system. The caustic is smaller than that of the large separation binary lens when the perturber is the first scatterer; the caustic is similar in size with the large separation binary lens when the perturber is the last scatterer. Modelling of a gravitational lensing by a galaxy requires extra terms other than constant shear for the perturbers at different redshifts. Double scattering two distributed mass (DSTD) lens is considered. The perturbing galaxy behaves as a monopole -- or a point mass -- because the dipole moment of the elliptic mass distribution is zero.
