Diversity and extracellular enzymatic activity of culturable yeasts isolated from soil in a Brazilian Amazonian rainforest biomeNARA Subscribed
The Amazon rainforest represents the largest and most biodiverse tropical rainforest in the world, comprising over half of the planet’s remaining rainforests. In this study, we investigated the yeast distribution in the soils in a Brazilian Amazonian rainforest biome. The collection sites included two upland forests, a black-water floodplain forest, and an Amazonian dark earth site. Yeasts were isolated using both enrichment a...
Biochar-driven shifts in the soil bacterial community structure of degraded semiarid soilsNARA Subscribed
Low biochar rates (5 Mg ha −1 ) increased bacterial richness and diversity in degraded soil. Biochar origin controlled microbial assembly and niche specialization patterns. Sewage-sludge biochar favored stress-tolerant and metal-adapted bacterial taxa. Cashew bagasse biochar enhanced nitrogen cycling and chemoheterotrophic functions. Network complexity peaked at intermediate biochar doses and declined at high rates. Biochar ha...
Integrative taxonomy of the Eurytemora velox (Copepoda, Calanoida) species complex reveals a new cryptic speciesNARA Subscribed
This study investigated the variability within populations of the copepod Eurytemora velox . Integrative taxonomy confirmed significant genetic heterogeneity among the studied populations supported the hypothesis of E. velox being a species complex. To assess morphological variability, morphometric traits and ordination analyses were utilized. For molecular assessment, the mitochondrial cytochrome c oxidase subunit 1 (COI) and...
Effects of repeated treatment with opioids that vary in mu opioid receptor efficacy on pain-depressed locomotor behavior in miceNARA Subscribed
Rationale Mu opioid receptor (MOR) analgesics like morphine have high intrinsic MOR efficacy but produce side effects. Lower efficacy MOR agonists like buprenorphine can produce analgesia with improved safety. We recently described a series of novel phenylmorphan-based MOR agonists with graded MOR efficacies, including several with sub-buprenorphine efficacies, and we described their acute effectiveness in mice to produce (a)...
Examining the Impact of Derelict Pots on Blue Crab ( Callinectes sapidus ) Catch and Harvest Within a Recreational FisheryNARA Subscribed
Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab ( Callinectes sapidus ) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections of Indian River Bay, DE. The observed environmental covariates, including temperatur...
Predation of Pterostichus melanarius on cocoons of soybean gall midge, Resseliella maximaNARA Subscribed
The soybean gall midge, Resseliella maxima Gagné (Diptera: Cecidomyiidae), feeds on soybean, Glycine max (L.) Merrill (Fabales: Fabaceae), causing significant injury and yield losses. Pterostichus melanarius Illiger (Coleoptera: Carabidae), a generalist predator introduced to North America, has been reported to prey on R. maxima larvae under laboratory conditions. Understanding the feeding preference of P. melanarius on differ...
Introduction Insufficiency of the future liver remnant (FLR) precludes surgery for liver tumors as it is associated with post-hepatectomy liver failure (PHLF). A common strategy to induce pre-operative FLR hypertrophy is portal vein embolization of the tumor bearing liver lobe. More recently, transarterial radio-embolization (radiation lobectomy, RL) has been employed. Direct functional assessment using 99mTc-mebrofenin-hepato...
Increased levels of cerebrospinal fluid (CSF) soluble platelet-derived growth factor receptor-β (sPDGFRβ), a marker of blood–brain barrier (BBB)-associated pericyte cell injury, have been shown to correlate with increased BBB permeability and severity of Alzheimer’s disease (AD) pathology. It has been also shown that increased CSF sPDGFRβ levels can predict cognitive dysfunction in APOE4 carriers bearing the main susceptibilit...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Distributed optical fibre sensing (DOFS) is a technology that enables continuous, real-time measurements of a range of environmental parameters along the length of a fibre optic cable. In this article, we review the recently emerged applications of DOFS techniques in physical oceanography and offer a perspective on the technology's potential for future growth within the field. The introduction of DOFS to physical oceanography...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
In 2023, more than half of olive harvests ( Olea europaea ) across Spain, Greece, and Türkiye were lost to drought. The same year late freeze destroyed 90% of the peach crop ( Prunus persica ) on the Georgia Piedmont and the apple crop ( Malus domestica ) in central New York, Vermont, and southern Quebec. Climate extremes now rank with the costliest threats to agriculture, but their role in forest recovery from diebacks that a...
