Complete spatiotemporal quantification of cardiac motion in mice through enhanced acquisition and super-resolution reconstruction.

The quantification of cardiac motion using cardiac magnetic resonance imaging (CMR) has shown promise as an early-stage marker for cardiovascular diseases. Despite the growing popularity of CMR-based myocardial strain calculations, measures of complete spatiotemporal strains (i.e.

Role of second look endoscopy in endoscopic submucosal dissection and peptic ulcer bleeding: Meta-analysis of randomized controlled trials.

Background: Second-look endoscopy (SLE) to prevent recurrent bleeding in patients with peptic ulcer disease (PUD) and those undergoing endoscopic submucosal dissection (ESD) is routinely being performed. Conflicting evidence exists regarding efficacy, risk, benefit, and cost-effectiveness.

Aim: To identify the role and effectiveness of SLE in ESD and PUD, associated rebleeding and PUD-related outcomes like mortality, hospital length of stay, need for endoscopic or surgical intervention and blood transfusions.

Astyanax mexicanus surface and cavefish chromosome-scale assemblies for trait variation discovery.

The ability of organisms to adapt to sudden extreme environmental changes produces some of the most drastic examples of rapid phenotypic evolution. The Mexican Tetra, , is abundant in the surface waters of northeastern Mexico, but repeated colonizations of cave environments have resulted in the independent evolution of troglomorphic phenotypes in several populations. Here, we present three chromosome-scale assemblies of this species, for one surface and two cave populations, enabling the first whole-genome comparisons between independently evolved cave populations to evaluate the genetic basis for the evolution of adaptation to the cave environment.

Episodes of Early Pleistocene West Antarctic Ice Sheet Retreat Recorded by Iceberg Alley Sediments.

Ice loss in the Southern Hemisphere has been greatest over the past 30 years in West Antarctica. The high sensitivity of this region to climate change has motivated geologists to examine marine sedimentary records for evidence of past episodes of West Antarctic Ice Sheet (WAIS) instability. Sediments accumulating in the Scotia Sea are useful to examine for this purpose because they receive iceberg-rafted debris (IBRD) sourced from the Pacific- and Atlantic-facing sectors of West Antarctica.

Dinner planning and preparation considerations of parents with children attending childcare.

The objective of this study was to explore the meal-related thought processes, planning, and purchasing behaviors of primary caregivers on weeknights. A mixed-methods study design was applied using a cross-sectional survey and qualitative interviews. Thirty-three primary caregivers from early childhood education centers were enrolled in the study.

High-fidelity quantum information transmission using a room-temperature nonrefrigerated lossy microwave waveguide.

Quantum microwave transmission is key to realizing modular superconducting quantum computers and distributed quantum networks. A large number of incoherent photons are thermally generated within the microwave frequency spectrum. The closeness of the transmitted quantum state to the source-generated quantum state at the input of the transmission link (measured by the transmission fidelity) degrades due to the presence of the incoherent photons.

Morphometric approach supports distinction among three species of Paucibranchia Molina-Acevedo, 2018 (Annelida: Eunicidae).

In this study, we performed a morphometric approach of 23 quantitative features of Paucibranchia bellii (Audouin Milne-Edwards, 1833), P. disjuncta (Hartman, 1961), and P. carrerai Molina-Acevedo, 2018 in order to evaluate their importance in interspecific discrimination.

Antiphased dust deposition and productivity in the Antarctic Zone over 1.5 million years.

The Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report a high-resolution record of dust deposition and ocean productivity for the Antarctic Zone, close to the main dust source, Patagonia. Our deep-ocean records cover the last 1.

Recent Advances in the Chemistry and Therapeutic Evaluation of Naturally Occurring and Synthetic Withanolides.

Natural products are a major source of biologically active compounds that make promising lead molecules for developing efficacious drug-like molecules. Natural withanolides are found in many flora and fauna, including plants, algae, and corals, that traditionally have shown multiple health benefits and are known for their anti-cancer, anti-inflammatory, anti-bacterial, anti-leishmaniasis, and many other medicinal properties. Structures of these withanolides possess a few reactive sites that can be exploited to design and synthesize more potent and safe analogs.

Barriers to consistent and reliable investigation of sudden unexpected infant death: Perspectives from law enforcement.

Despite persistent efforts to advance infant death investigation, most sudden unexpected infant deaths (SUIDs) remain unexplained. Law enforcement officials contribute to SUID investigations throughout the United States, but their impacts on these investigations have not been adequately examined. In this exploratory study, 26 law enforcement officials were interviewed about their experiences and perspectives with SUID investigations.

Taxonomic notes on the Australian skyhopper genus Kosciuscola Sjstedt (Orthoptera: Acrididae: Oxyinae).

The Australian skyhopper genus Kosciuscola Sjstedt consists of brachypterous species that inhabit the Australian alpine and subalpine region. The genus used to include 5 species and 1 subspecies, but according to a recent phylogenomic study, there could be as many as 14 species in the genus, that are genetically and geographically isolated from each other. This study represents the first step in describing and documenting the diversity of this interesting genus.

Long-Time Memory and Ternary Logic Gate Using a Multistable Cavity Magnonic System.

Multistability is an extraordinary nonlinear property of dynamical systems and can be explored to implement memory and switches. Here we experimentally realize the tristability in a three-mode cavity magnonic system with Kerr nonlinearity. The three stable states in the tristable region correspond to the stable solutions of the frequency shift of the cavity magnon polariton under specific driving conditions.

High Survivorship of First-Generation Monarch Butterfly Eggs to Third Instar Associated with a Diverse Arthropod Community.

Based on surveys of winter roost sites, the eastern migratory population of the monarch butterfly () in North America appears to have declined in the last 20 years and this has prompted the implementation of numerous conservation strategies. However, there is little information on the survivorship of first-generation monarchs in the core area of occupancy in Texas, Oklahoma, and Louisiana where overwinter population recovery begins. The purpose of this study was to determine the survivorship of first-generation eggs to third instars at a site in north Texas and to evaluate host plant arthropods for their effect on survivorship.

An Illustrated Key of Pyrgomorphidae (Orthoptera: Caelifera) of the Indian Subcontinent Region.

The Indian subcontinent is known to harbor a high level of insect biodiversity and endemism, but the grasshopper fauna in this region is poorly understood, in part due to the lack of appropriate taxonomic resources. Based on detailed examinations of museum specimens and high-resolution digital images, we have produced an illustrated key to 21 Pyrgomorphidae genera known from the Indian subcontinent. This new identification key will become a useful tool for increasing our knowledge on the taxonomy of grasshoppers in this important biogeographic region.

Kinetic Behavior of Quaternary Ammonium Hydroxides in Mixed Methane and Carbon Dioxide Hydrates.

This study evaluates the kinetic hydrate inhibition (KHI) performance of four quaternary ammonium hydroxides (QAH) on mixed CH + CO hydrate systems. The studied QAHs are; tetraethylammonium hydroxide (TEAOH), tetrabutylammonium hydroxide (TBAOH), tetramethylammonium hydroxide (TMAOH), and tetrapropylammonium hydroxide (TPrAOH). The test was performed in a high-pressure hydrate reactor at temperatures of 274.

Unusual opecoelids from Red Sea triggerfishes with special reference to characteristic concepts of the Opistholebetinae Fukui, 1929 (Digenea: Opecoelidae).

Three digeneans belonging to the Opecoelidae are reported and described from triggerfishes (Tetraodontiformes: Balistidae) collected in the northern Red Sea off Egypt. Both Macvicaria longicirrata (Manter, 1963) Aken-Ova, Cribb Bray, 2008 and Neopycnadena tendu (Bray Justine, 2007) n. comb.

A new genus and species of Anchitrematidae Mehra, 1935 (Digenea: Gorgoderoidea) in a freshwater fish from the River Nile at Qena, Egypt with amendation of the family.

Museum specimens of a previously unknown species of the Anchitrematidae from a freshwater fish collected from the River Nile at Qena, Egypt were examined. This species is somewhat similar to species of Anchitrema, but was found to have a thick, continuous, shelf-like rim around the periphery of the ventral aspect of the distome, the lateral aspect of the forebody was composed of large internal patches of lightly vacuolated, somewhat glandular cells that formed pad-like structures (pelops-like structures), and it possessed a uterine seminal receptacle; characteristics that previously have not been found in any species in the family. Species currently assigned to Anchitrema or Mujibia (the only two genera in the family) are known only from reptiles and mammals and no species has previously been reported from a freshwater fish.

A new species of freshwater mussel in the genus Popenaias Frierson, 1927, from the Gulf coastal rivers of central Mexico (Bivalvia: Unionida: Unionidae) with comments on the genus.

The Gulf coastal drainages of central Mexico are a faunal transition zone between North and South America and harbor a unique assemblage of freshwater mussels (Bivalvia: Unionida). However, little information is available regarding the taxonomy, distribution, and evolutionary history of the Mexican mussel fauna due to limited sampling over the last 100 years. To address these knowledge gaps, we evaluated species-level diversity in the genus Popenaias Frierson, 1927, in Mexican Gulf coastal drainages as part of a larger effort to inform conservation efforts for members of this genus both in Mexico and the United States of America.

Hybrid two-mode squeezing of microwave and optical fields using optically pumped graphene layers.

A measurable quadrature of a squeezed quantum state manifests a small uncertainty below the Heisenberg limit. This phenomenon has the potential to enable several extraordinary applications in quantum information, metrology and sensing, and other fields. Several techniques have been implemented to realize squeezed electromagnetic states, including microwave fields and optical fields.
