Only a few Impatiens spp. from South India (one of the five centers of diversity for Impatiens species) were included in the published datum of molecular phylogeny of the family Balsaminaceae. The present investigation is a novel attempt to reveal the phylogenetic association of Impatiens species of South India, by placing them in the global phylogeny of Impatiens based on a combined analysis of two chloroplast genes. Thirty species of genus Impatiens were collected from different locations of South India. Total genomic DNA was extracted from fresh plant leaf, and polymerase chain reaction was carried out using atpB-rbcL and trnL-F intergenic spacer-specific forward and reverse primers...

Temperate and dry deciduous forest covers major portion of terrestrial ecosystem in India. The two forest types with different dominant tree species differ in litter quality and root exudates, thereby exerting species-specific impact on soil properties and microbial activity. This study aims to examine the influence of forest type or dominant tree species on soil physico-chemical properties and its relationship with microbial characters in temperate and dry deciduous forest types. We assessed soil physico-chemical properties among five different sites located within the selected forest stand covered by different dominant species...

Phylogenetic relationship of 22 FLPs was revealed on the basis of polymorphism in three genes namely 16S rDNA, Pseudomonas-specific and rpoD gene regions. The primers for 16S rDNA, Pseudomonas-specific region and rpoD gene region were amplifying a region of 1492, 990 and 760 bp, respectively, from all the isolates investigated. The RFLP analysis of the PCR products resulted in a classification of these fluorescent pseudomonads which was best answered by rpoD-based RFLP analysis. The 22 FLPs were placed in two major clusters and seven subclusters suggesting that these were genotypically heterogenous and might belong to several species within Pseudomonas sensu stricto...

Large-scale expression of biopharmaceutical proteins in cellular hosts results in production of large insoluble mass aggregates. In order to generate functional product, these aggregates require further processing through refolding with denaturant, a process in itself that can result in aggregation. Using a model folding protein, cytochrome C, we show how an increase in final denaturant concentration decreases the propensity of the protein to aggregate during refolding. Using polarised fluorescence anisotropy, we show how reduced levels of aggregation can be achieved by increasing the period of time the protein remains flexible during refolding, mediated through dilution ratios...

PURPOSE: Exploration of the human retina has never been described with MRI tractography, supposedly because of ocular movement-related artifacts and imaging distortions with EPI diffusion acquisition. In this work, we used track-weighting imaging to assess retinal fascicles. Diffusion acquisition parameters influence was studied and the relationship between variability and ocular laterality and ocular dominance was explored. MATERIALS AND METHODS: Twenty healthy subjects underwent MRI, with retinal tractography calculated with the constrained spherical deconvolution model...

Aagje Swinnen, Kate de Medeiros
This paper is a humanities-based inquiry, applying Huizinga's framework of homo ludens ("man the player") to consider "play" in the context of two participatory arts programs (TimeSlips and the Alzheimer's Poetry Project) for people living with dementia. "Play," according to this Dutch historian, is at the heart of human activity and what gives meaning to life. Despite empirical research on play across the life course, play in dementia care is a relatively new idea. In addition, there is a dearth of reports based on humanistic inquiry which has slightly different goals than the growing body of qualitative and quantitative studies of participatory arts interventions...

Objectives: Research suggests that abuser risk factors differ across elder mistreatment types, but abuse interventions are not individualized. To move away from assumptions of perpetrator homogeneity and to inform intervention approaches, this study classifies abusers into subtypes according to their behavior profiles. Method: Data are from the Older Adult Mistreatment Assessment administered to victims by Adult Protective Service (APS) in Illinois. Latent class analysis was used to categorize abusers (N = 336) using victim and caseworker reports on abusers' harmful and supportive behaviors and characteristics...

Purpose of the Study: Adult daughters providing care to aging, ill mothers comprise the most prevalent caregiving dyad. Little is known, however, regarding relationship quality and its impact on care in these dyads, particularly in the context of cognitively intact patients at end of life in hospice. This interpretive descriptive work privileges voices of terminally ill mothers and care-partnering daughters in the home hospice context. Specific aims were to describe and interpret how mothers and daughters: (a) perceive relationship quality and (b) perceive how relationships have developed over time through health, chronic illness, and hospice...
