Academic literature on the topic 'Opelousas, La'

Abstract The third speaker will be the industry partner representative, Kenneth Cochran, President and CEO of Opelousas General Health System. Here we will hear from industry partners about what drew them to this program of inter-collaboration; the benefits they have received, and what was required of them to participate. This will be helpful as it will provide an opportunity to have a first-hand account about the value that practitioners find in this program as it relates to testing interventions, developing new systems, and improving financial performance and/or quality. Kenneth will speak to a particular project at Opelousas and describe entire process. Kenneth will highlight the challenges and opportunities that come from partnering with an academic institution. Also, how CHOT brings together industry partners who are facing the same challenges and how they learn and adopt best practices from each other. This should further illustrate the value that academic/industry collaboration can bring.

Pond populations in Cape Cod described as Persicaria puritanorum (≡ Polygonum puritanorum) have been treated by recent authors as a synonym of P. maculosa (≡ Polygonum persicaria) based on gross morphology. However, consistent differences in leaf and inflorescence features raise the question as to whether this is an extreme phenotype of P. maculosa, an ecotype of that species, or a distinct taxon. In this study, we analyzed nuclear ITS region and chloroplast matK region DNA sequences from 37 populations of 11 species within section Eupersicaria and counted the chromosome number of individuals from the pond populations in question. We also compared leaf size and shape of plants from these populations with those of the typical P. maculosa plants by measuring selected herbarium specimens. Phylogenetic trees inferred from sequence data indicate a separation of pond populations from P. maculosa suggesting to recover P. puritanorum as a distinct species. Chromosome counts of pond population plants (2n = 60) strongly support this result, and furthermore suggest the possibility of a hybrid polyploid origin of P. puritanorum. A leaf morphological trait (greater relative height of the maximum width point from the leaf base) also supports the separation of pond populations from P. maculosa. P. punctata allied to P. hydropiper in the ITS-based tree, and to pond populations as well as P. hydropiperoides and P. opelousana in the matK-based tree, suggesting the possibility of hybrid origin of P. punctata. Our ITS sequence analyses also reveal distinct two lineages in P. lapathifolia but the chloroplast matK region sequences of P. pensylvanica and two lineages of P. lapathifolia are almost identical suggesting cytoplasmic introgression or allopolyploid speciation sharing the maternal lineage.
