The InBIO barcoding initiative database: DNA barcodes of Iberian Trichoptera, documenting biodiversity for freshwater biomonitoring in a Mediterranean hotspot
Get PDFBackground
The Trichoptera are an important component of freshwater ecosystems. In the Iberian Peninsula, 380 taxa of caddisflies are known, with nearly 1/3 of the total species being endemic in the region. A reference collection of morphologically identified Trichoptera specimens, representing 142 Iberian taxa, was constructed. The InBIO Barcoding Initiative (IBI) Trichoptera 01 dataset contains records of 438 sequenced specimens. The species of this dataset correspond to about 37% of Iberian Trichoptera species diversity. Specimens were collected between 1975 and 2018 and are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources, Portugal) or in the collection Marcos A. González at the University of Santiago de Compostela (Spain).
New information
Twenty-nine species, from nine different families, were new additions to the Barcode of Life Data System (BOLD). A success identification rate of over 80% was achieved when comparing morphological identifications and DNA barcodes for the species analysed. This encouraging step advances incorporation of informed Environmental DNA tools in biomonitoring schemes, given the shortcomings of morphological identifications of larvae and adult Caddisflies in such studies. DNA barcoding was not successful in identifying species in six Trichoptera genera: Hydropsyche (Hydropsychidae), Athripsodes (Leptoceridae), Wormaldia (Philopotamidae), Polycentropus (Polycentropodidae) Rhyacophila (Rhyacophilidae) and Sericostoma (Sericostomatidae). The high levels of intraspecific genetic variability found, combined with a lack of a barcode gap and a challenging morphological identification, rendered these species as needing additional studies to resolve their taxonomy
Cemeteries
Get PDFThe first house we bought in West Virginia was sandwiched between two cemeteries. The larger one stood behind our house and was hidden by a patch of trees, so we could see it only in the winter when the trees lost their leaves and the headstones emerged, rectangular specks visible between the bare branches. The smaller cemetery perched on top of a low hill across from our house, on the other side of the narrow, dead-end street

Stop Apologizing: A Review of John Guillory\u27s Professing Criticism
Get PDFIn this review, I provide at look into the recently published text Professing Criticism: Essays on the Organization of Literary Study. In doing so, I explore the strengths and weaknesses of the text from a distanced perspective, with some particular attention to the relevance of the text to literary scholars with political orientations and connections to the history of theory

Relationship between the Hospital Readmission Reduction Program and Readmissions, Postoperative Complications, and Cost
Get PDFHospital readmissions have contributed significantly to rising healthcare costs in the United States. To curb rising costs, the Centers for Medicare and Medicaid Services introduced the Hospital Readmissions Reduction Program (HRRP), a penalty-based program designed to decrease healthcare costs. This research aims to determine if the HRRP has successfully reduced healthcare costs and increased quality outcomes associated with total knee arthroplasty (TKA) or total hip arthroplasty (THA) as defined by a reduction in readmission rates, postoperative complications, and overall costs. Although a positive correlation has been shown between outcomes and costs post-HRRP, more research is needed to tease out the impact of HRRP on these findings, given that these indicators were already positively trending before implementation
Genome-wide DNA methylation analysis in schizophrenia with tardive dyskinesia: a preliminary study
No full textObjectives
The trail making test part B (TMT-B) evaluates executive functions, memory, and sensorimotor functions. No previous study was found to examine the longitudinal effect of APOE-ε4 genotypes on the TMT-B scores in Alzheimer\u27s disease (AD) across racial groups. Methods
This study used the data from Alzheimer\u27s Disease Neuroimaging Initiative (ADNI): 382 participants with AD, 503 with cognitive normal (CN), 1293 with mild cognitive impairment (MCI) at baseline and follow-up of four years. The multivariable linear mixed model was used to investigate the effect of APOE-ε4 genotypes on changes in TMT-B scores. Results
Compared with Whites, African Americans (AA) and Hispanics had higher TMT-B scores (poor cognitive function). Furthermore, Whites subjects with 1 or 2 APOE-ε4 alleles had significantly higher TMT-B scores compared with individuals without APOE-ε4 allele at baseline and four follow-up visits; however, no differences in TMT-B were found between APOE-ε4 alleles in the Hispanic and AA groups. No APOE-ε4 by visit interactions was found for 3 racial groups. Stratified by AD diagnosis, the APOE-ε4 allele was associated with TMT-B scores only in the MCI group, while there were significant interactions for visit by education, APOE-ε4 allele, and the Mini Mental State Examination (MMSE) score in the MCI group. In addition, TMT-B was significantly correlated with the MMSE, AD Assessment Scale-cognitive subscale 13 (ADAS13), tTau, pTau, Aβ42, and hippocampus. Conclusions
APOE-ɛ4 allele is associated with TMT-B scores in Whites subjects, but not in the Hispanic and AA groups. APOE-ε4 showed interaction with visit in the MCI group
