Zooplankton entrainment at the Surry Nuclear Power Plant, James River, Virginia : final report

The diverse zooplankton found in marine and estuarine waters serves an important role in food chains, converting phytoplankton and detrital material into protein rich animal tissues necessary in the nutrition of higher life forms, such as the young stages of decapod crustaceans and fishes. Generally free-floating or only weak swimmers, zooplankters are readily entrained in cooling waters pumped into power plants. Mortality of entrained organisms can be caused by mechanical abrasion, the length of time and amplitude of temperature increases during plant passage, and from chlorination of the system for fouling control. Estimates of the percent of mortality due to plant passage are difficult to obtain, however, because of the many variables that need to be taken into account. This project was designed to examine several of these variables as they apply to entrained zooplankton at the VEPCO Surry plant

Effects Of Tropical Storm Agnes On Zooplankton In The Lower Chesapeake Bay

Sampling techniques in use since August 1971 were employed to study effects of Tropical Storm Agnes on lower Chesapeake Bay zooplankton following the storm\u27s passage on June 21, 1972. Mean catches of copepods, cladocerans, barnacle larvae, decapod larvae, chaetognaths, and fish eggs and larvae were calculated for the entire study area and six subareas from 8 bongo net collections. A single subarea was selected for specific identifications within major taxa of zooplankton.https://scholarworks.wm.edu/vimsbooks/1072/thumbnail.jp

Superresolution Pattern Recognition Reveals the Architectural Map of the Ciliary Transition Zone

The transition zone (TZ) of primary cilia serves as a diffusion barrier to regulate ciliogenesis and receptor localization for key signaling events such as sonic hedgehog signaling. Its gating mechanism is poorly understood due to the tiny volume accommodating a large number of ciliopathy-associated molecules. Here we performed stimulated emission depletion (STED) imaging of collective samples and recreated superresolved relative localizations of eight representative species of ciliary proteins using position averages and overlapped with representative electron microscopy (EM) images, defining an architectural foundation at the ciliary base. Upon this framework, transmembrane proteins TMEM67 and TCTN2 were accumulated at the same axial level as MKS1 and RPGRIP1L, suggesting that their regulation roles for tissue-specific ciliogenesis occur at a specific level of the TZ. CEP290 is surprisingly localized at a different axial level bridging the basal body (BB) and other TZ proteins. Upon this molecular architecture, two reservoirs of intraflagellar transport (IFT) particles, correlating with phases of ciliary growth, are present: one colocalized with the transition fibers (TFs) while the other situated beyond the distal edge of the TZ. Together, our results reveal an unprecedented structural framework of the TZ, facilitating our understanding in molecular screening and assembly at the ciliary base

Enabling multiplexed testing of pooled donor cells through whole-genome sequencing

We describe a method that enables the multiplex screening of a pool of many different donor cell lines. Our method accurately predicts each donor proportion from the pool without requiring the use of unique DNA barcodes as markers of donor identity. Instead, we take advantage of common single nucleotide polymorphisms, whole-genome sequencing, and an algorithm to calculate the proportions from the sequencing data. By testing using simulated and real data, we showed that our method robustly predicts the individual proportions from a mixed-pool of numerous donors, thus enabling the multiplexed testing of diverse donor cells en masse.National Human Genome Research Institute (U.S.) (Grant RM1HG008525)Robert Wood Johnson Foundation (Grant 74178

Quality of Dementia Care in the Community: Identifying Key Quality Assurance Components

Background: Primary care-based memory clinics (PCMCs) have been established in several jurisdictions to improve the care for persons with Alzheimer’s disease and related dementias. We sought to identify key quality indicators (QIs), quality improvement mechanisms, and potential barriers and facilitators to the establishment of a quality assurance framework for PCMCs. Methods: We employed a Delphi approach to obtain consensus from PCMC clinicians and specialist physicians on QIs and quality improvement mechanisms. Thirty-eight candidate QIs and 19 potential quality improvement mechanisms were presented to participants in two rounds of electronic Delphi surveys. Written comments were collected and descriptively analyzed. Results:The response rate for the first and second rounds were 21.3% (n = 179) and 12.8% (n = 88), respectively. The majority of respondents were physicians. Fourteen QIs remained after the consensus process. Ten quality improvement mechanisms were selected with those characterized by specialist integration, such as case discussions and mentorships, being ranked highly. Written comments revealed three major themes related to potential barriers and facilitators to quality assurance: 1) perceived importance, 2) collaboration and role clarity, and 3) implementation process.Conclusion:We successfully utilized a consultative process among primary and specialty providers to identify core QIs and quality improvement mechanisms for PCMCs. Identified quality improvement mechanisms highlight desire for multi-modal education. System integration and closer integration between PCMCs and specialists were emphasized as essential for the provision of high-quality dementia care in community settings.Alzheimer Society of Canada, Canadian Institutes of Health Research (CIHR), Schlegel-University of Waterloo-Research Institute for Agin

The Chlamydomonas reinhardtii BBSome is an IFT cargo required for export of specific signaling proteins from flagella

In humans, seven evolutionarily conserved genes that cause the cilia-related disorder Bardet-Biedl syndrome (BBS) encode proteins that form a complex termed the BBSome. The function of the BBSome in the cilium is not well understood. We purified a BBSome-like complex from Chlamydomonas reinhardtii flagella and found that it contains at least BBS1, -4, -5, -7, and -8 and undergoes intraflagellar transport (IFT) in association with a subset of IFT particles. C. reinhardtii insertional mutants defective in BBS1, -4, and -7 assemble motile, full-length flagella but lack the ability to phototax. In the bbs4 mutant, the assembly and transport of IFT particles are unaffected, but the flagella abnormally accumulate several signaling proteins that may disrupt phototaxis. We conclude that the BBSome is carried by IFT but is an adapter rather than an integral component of the IFT machinery. C. reinhardtii BBS4 may be required for the export of signaling proteins from the flagellum via IFT

N-Terminal Pro-B-Type Natriuretic Peptide and Microsize Myocardial Infarction Risk in the Reasons for Geographic and Racial Differences in Stroke Study

Background: N-terminal pro B-type peptide (NT-proBNP) has been associated with risk of myocardial infarction (MI), but less is known about the relationship between NT-proBNP and very small non ST-elevation MI, also known as microsize MI. These events are now routinely detectable with modern troponin assays and are emerging as a large proportion of all MI. Here, we sought to compare the association of NT-proBNP with risk of incident typical MI and microsize MI in the REasons for Geographic and Racial Differences in Stroke (REGARDS) Study. Methods: The REGARDS Study is a national cohort of 30,239 US community-dwelling black and white adults aged ≥ 45 years recruited from 2003 to 2007. Expert-adjudicated outcomes included incident typical MI (definite/probable MI with peak troponin ≥ 0.5 μg/L), incident microsize MI (definite/probable MI with peak troponin \u3c 0.5 μg/L), and incident fatal CHD. Using a case-cohort design, we estimated the hazard ratio of the outcomes as a function of baseline NT-proBNP. Competing risk analyses tested whether the associations of NT-proBNP differed between the risk of incident microsize MI and incident typical MI as well as if the association of NT-proBNP differed between incident non-fatal microsize MI and incident non-fatal typical MI, while accounting for incident fatal coronary heart disease (CHD) as well as heart failure (HF). Results: Over a median of 5 years of follow-up, there were 315 typical MI, 139 microsize MI, and 195 incident fatal CHD. NT-proBNP was independently and strongly associated with all CHD endpoints, with significantly greater risk observed for incident microsize MI, even after removing individuals with suspected HF prior to or coincident with their incident CHD event. Conclusion: NT-proBNP is associated with all MIs, but is a more powerful risk factor for microsize than typical MI
