Implantable left ventricular assist systems (LVASs) are used for bridging to transplantation, myocardial improvement, and permanent circulatory support. Conventional implantable have inherent limitations that increase morbidity during In contrast, small, efficient, axial-flow pumps, which been under development the past decade, potential improve length quality of life in patients with severe heart failure. Methods Results- To assess safety clinical utility Jarvik 2000, we implanted this...
Abstract Comparisons between historical and recent ecological datasets indicate that shallow reef habitats across the central Galapagos Archipelago underwent major transformation at time of severe 1982/1983 El Niño warming event. Heavily grazed reefs with crustose coralline algae (‘urchin barrens’) replaced former macroalgal coral habitats, resulting in large local regional declines biodiversity. Following threat assessment workshops, a total five mammals, six birds, reptiles, fishes, one...
Gabrielson P.W., Miller K.A. and Martone P.T. 2011. Morphometric molecular analyses confirm two distinct species of Calliarthron (Corallinales, Rhodophyta), a genus endemic to the northeast Pacific. Phycologia 50: 298–316. DOI: 10.2216/10-42.1Phylogenetic rbcL sequences demonstrate that as currently constituted is paraphyletic. yessoense C. latissimum from northwest Pacific belong in Alatocladia are conspecific. After transfer latissimum, monophyletic, known only comprises species,...
Preimplantation genetic testing (PGT) has been successfully applied to reduce the risk of miscarriage, improve IVF success rates, and prevent inheritance monogenic disease unbalanced translocations. The present study provides first method capable simultaneous aneuploidy (PGT-A), structural rearrangements (PGT-SR), (PGT-M) disorders using a single platform. Using positive controls establish performance characteristics, accuracies 97 >99% for each type were observed. In addition, this expands...
Purpose: Gemcitabine has shown a broad range of activity in solid tumors, including previously untreated small-cell lung cancer (SCLC). The objective this phase II trial was to investigate the gemcitabine patients with relapsed SCLC. Patients and Methods: SCLC measurable disease who had experienced treatment failure one prior chemotherapy regimen were considered eligible. required have Eastern Cooperative Oncology Group (ECOG) performance status 0 2 adequate organ function; signed informed...
Abstract The Galapagos Marine Reserve provides refuge for numerous threatened marine species, including 16 mammals, birds, reptiles and fish currently recognized on the 2006 IUCN Red List of Threatened Species, plus an additional 25 endemic fish, mollusc, crustacean, echinoderm, coral macroalgal species that comply with criteria because declining extent occurrence or highly‐localized ranges, hence also qualify inclusion List. restricted ranges are not randomly distributed across archipelago...
Plant species, including algae and fungi, are based on type specimens to which the name of a taxon is permanently attached. Applying scientific any specimen therefore requires demonstrating correspondence between that specimen. Traditionally, identifications morpho-anatomical characters, but recently systematists using DNA sequence data. These studies flawed if isolated from misidentified modern specimens. We propose genome-based solution. Using 4 × mm2 material specimens, we assembled 14...
Abstract Misapplication of Ulva epithets in GenBank has led to confusion the scientific literature and community. To solve some problems, targeted DNA sequencing plastid encoded rbc L gene amplicons or high-throughput was performed on all blade-forming type specimens from northeast Pacific. Recently collected at near localities were also analyzed for taxa. Based these genetic analyses, we confirmed currently recognized species: U. californica , with angusta scagelii as heterotypic synonyms,...
Three species of benthic marine macroalgae comprise the chief components seaweed flora McMurdo Sound, Antarctica. Quantitative studies at Cape Evans demonstrate a depth-related distribution pattern, with Iridaea cordata (Turner) Bory in shallow water, Phyllophora antarctica A. and E. S. Gepp abundant fertile intermediate depths, Leptophytum coulmanicum (Foslie) Adey dominant below 20 m. The vertical is correlated irradiance levels. At sites thinner annual sea ice less snow accumulation...
Abstract The integration of foreign DNA into algal and plant plastid genomes is a rare event, with only few known examples horizontal gene transfer (HGT). Plasmids, which are well-studied drivers HGT in prokaryotes, have been reported previously red algae (Rhodophyta). However, the distribution these mobile elements their sites (ptDNA), mitochondrial (mtDNA), nuclear Rhodophyta remain unknown. Here we reconstructed complex evolutionary history plasmid-derived DNAs algae. Comparative analysis...
Abstract DNA sequences from type specimens provide independent, objective characters that enhance the value of and permit correct application species names to phylogenetic clades specimens. We mitochondrial genomes (mitogenomes) archival ten in agar-producing red algal genera Gelidium Pterocladiella . The contain 43–44 genes, ranging size 24,910 24,970 bp with highly conserved gene synteny. Low Ka/Ks ratios apocytochrome b cytochrome oxidase genes support their utility as markers....
Currently, the Scientific Working Group on DNA Analysis Methods (SWGDAM) mtDNA dataset is used to infer relative rarity of profiles (i.e., haplotypes) obtained from evidence samples and for identification missing persons. The Caucasian haplogroup patterns in this forensic have been characterized using phylogenetic methods. assessment reveals that relevant representative U.S. European Caucasians. comparisons carried out were both observation variable sites within control region (CR) selection...
Abstract We have developed a publicly available tool, AxonJ, which quantifies the axons in optic nerve sections of rodents stained with paraphenylenediamine (PPD). In this study, we compare AxonJ’s performance to human experts on 100x and 40x images obtained from multiple strains mice, including mice defects relevant glaucoma. AxonJ produced reliable axon counts high sensitivity 0.959 precision 0.907, repeatability 0.95 when compared gold-standard manual assessments correlation 0.882...
PREMISE OF THE STUDY: Phenotypic plasticity and convergent evolution have long complicated traditional morphological taxonomy. Fortunately, DNA sequences provide an additional basis for comparison, independent of morphology. Most importantly, by obtaining from historical type specimens, we are now able to unequivocally match species names genetic groups, often with surprising results. Methods: We used integrative taxonomic approach identify describe Northeast Pacific pinnately branched in...
SUMMARY Genetic analysis of type material various Ulva species has shown that many names have been misapplied. DNA sequences two the specimens on lectotype sheet U. australis from South Australia showed is conspecific with called pertusa Japan. However, not sequenced, nor other localities in Japan and Australia, including conglobata f. densa former, laetevirens spathulata latter. To determine if these correctly applied, targeted sequencing rbc L gene was performed (i) specimen , (ii) syntype...
Phycologists have hypothesized that the diminutive fronds produced by species in genera Chiharaea and Yamadaia, which are composed of comparatively few genicula intergenicula, represent morphological intermediates evolution articulated corallines from crustose ancestors. We test this "intermediate frond hypothesis" comparing rbcL sequences generitype bodegensis Yamadaia melobesioides to other coralline genera. demonstrate includes two NE Pacific species, Arthrocardia silvae americana....
Abstract Agarum is a perennial kelp genus that has broad distribution from the northwest Pacific to Atlantic Ocean. In order address questions regarding phylogenetic relationships and present‐day patterns of species within this genus, we analyzed nuclear ITS2, mitochondrial cox1 cox3, plastid RuBisCO spacer subset 130 samples plus Thalassiophyllum Costaria. All analyses individual markers ITS2 + cox3 dataset consistently produced clade included . The consisted two well‐resolved subclades:...
An unknown species of marine sea lettuce was observed forming green tides consecutive years from 2014 to 2016 in Seaside, California. This Ulva sp. similar thallus size and shape U. expansa. To confirm this identification, whole genome sequencing performed on the bloom-forming holotype specimen The complete tide mitogenome is 64,143 bp length, contains 65 genes, displays high gene synteny with pertusa Kjellman. incomplete for expansa, but analysis yielded mitoexome, plastid, nuclear genetic...
