Understanding Titan's Prebiotic Chemistry: Synthesizing Amino Acids Through Aminonitrile Alkaline Hydrolysis.

ACS Earth Space Chem

December 2024

Planetary Environments Laboratory NASA/GSFC, Greenbelt, Maryland 20771, United States.

Titan is an ocean world with a plethora of organic material in its atmosphere and on its surface, making it an intriguing location in the search for habitable environments beyond Earth. Settled aerosols will mix with transient surface melts following cryovolcanic eruptions and impact events, driving hydrolysis reactions and prebiotic chemistry. Previous studies have shown that the hydrolysis of laboratory-synthesized Titan organics leads to the production of amino acids and other prebiotic molecules.

Invertebrate herbivores influence seagrass wasting disease dynamics.

Ecology

December 2024

Department of Ecology and Evolutionary Biology, Cornell University, Ithaca, New York, USA.

Although invertebrate herbivores commonly impact terrestrial plant diseases by facilitating transmission of plant pathogens and increasing host susceptibility to infection via wounding, less is known about the role of herbivores in marine plant disease dynamics. Importantly, transmission via herbivores may not be required in the ocean since saline ocean waters support pathogen survival and transmission. Through laboratory experiments with eelgrass (Zostera marina), we showed that isopods (Pentidotea wosnesenskii) and snails (Lacuna spp.

Adverse Childhood Events (ACEs) are associated with increased vulnerability for posttraumatic stress disorder (PTSD), but not everyone who experiences ACEs develops PTSD. Impulsivity has gained interest as a potential mediator between ACEs and PTSD, given that both PTSD and ACEs have been closely related to impulsivity. However, less is known about the relationship within the context of substance use disorder (SUD), a population highly vulnerable to co-occurring PTSD.

  • Antidepressants are commonly prescribed to older adults for depression, but their impact on recovery after hip fractures is not well understood.
  • A study involving nearly 18,000 older adults with depression who underwent hip fracture surgery found that those using antidepressants before the injury had shorter hospital stays.
  • The findings suggest that antidepressant use does not hinder recovery post-hip fracture and may even be beneficial, with no significant differences based on sex noted in the results.

Optimizing EPR pulses for broadband excitation and refocusing.

J Magn Reson

December 2024

Department of Physics, University of Maryland Baltimore County, Baltimore, MD 21250, USA. Electronic address:

In this paper, we numerically optimize broadband pulse shapes that maximize Hahn echo amplitudes. Pulses are parameterized as neural networks (NN), nonlinear amplitude limited Fourier series (FS), and discrete time series (DT). These are compared to an optimized choice of the conventional hyperbolic secant (HS) pulse shape.

Sea surface salinity ([Formula: see text]) is a key parameter in the thermohaline circulation of global oceans. Near the megadeltas, inland streamflow through large catchments plays a crucial role in mediating salinity. While some regional studies have investigated how [Formula: see text] is impacted through water cycle and climate components, a global scale quantification of inland streamflow contribution on [Formula: see text] variability is lacking.

A Method for Multimodal IVA Fusion Within a MISA Unified Model Reveals Markers of Age, Sex, Cognition, and Schizophrenia in Large Neuroimaging Studies.

Hum Brain Mapp

December 2024

Tri-Institutional Center for Translational Research in Neuroimaging and Data Science (TReNDS), Georgia State University, Georgia Institute of Technology, and Emory University, Atlanta, Georgia, USA.

With the increasing availability of large-scale multimodal neuroimaging datasets, it is necessary to develop data fusion methods which can extract cross-modal features. A general framework, multidataset independent subspace analysis (MISA), has been developed to encompass multiple blind source separation approaches and identify linked cross-modal sources in multiple datasets. In this work, we utilized the multimodal independent vector analysis (MMIVA) model in MISA to directly identify meaningful linked features across three neuroimaging modalities-structural magnetic resonance imaging (MRI), resting state functional MRI and diffusion MRI-in two large independent datasets, one comprising of control subjects and the other including patients with schizophrenia.

Zinc selenide is an excellent matrix material to dope with rare-earth and transition metal to achieve mid-infrared luminescence to develop high power lasers. The luminescence, morphology and refractive index is significantly affected by the doping and defects generated due to size and valency of dopants, concentration, growth process and convection during the growth. The aim of the study is to investigate effect of point and line defects generated due to low doping of iron and chromium on the emission and morphology of the zinc selenide.

Mother-child closeness, a mutually trusting and affectionate bond, is an important factor in shaping positive youth development. However, little is known about the neural pathways through which mother-child closeness is related to brain organization. Utilizing a longitudinal sample primarily from low-income families (N = 181; 76% African American youth and 54% female), this study investigated the associations between mother-child closeness at ages 9 and 15 years and structural connectivity organization (network integration, robustness, and segregation) at age 15 years.

Endocrinology

October 2024

Institute of Marine & Environmental Technology, Department of Marine Biotechnology, University of Maryland Baltimore County, Baltimore, MD 21202, USA.

GnRH governs reproduction by regulating pituitary gonadotropins. Unlike most vertebrates, gnrh-/- zebrafish are fertile. To elucidate the role of the hypophysiotropic-Gnrh3 and other mechanisms regulating pituitary gonadotropes, we profiled the gene expression of all individual pituitary cells of wild-type and gnrh3-/- adult female zebrafish.

Liquid crystalline collagen assemblies as substrates for directed alignment of human Schwann cells.

Soft Matter

November 2024

Ralph E. Martin Department of Chemical Engineering, University of Arkansas, 3202 Bell Engineering Center, Fayetteville, AR, 72701, USA.

Article Synopsis
  • Collagen plays a crucial role in the extracellular matrix (ECM) and its orientation is essential for replicating cellular environments, but creating large-scale aligned collagen structures is challenging.
  • Type I collagen can self-assemble into liquid crystalline mesophases at acid conditions and high concentrations, which aids in aligning collagen on substrates, but processing these high concentrations presents difficulties.
  • This study successfully achieves centimeter-scale alignment of collagen on glass substrates at lower concentrations, and extends this alignment to 3-D hydrogels, showing that the alignment influences the orientation of human Schwann cells, with a model estimating the magnetic field needed for future studies on collagen alignment.

Motor impairments caused by stroke significantly affect daily activities and reduce quality of life, highlighting the need for effective rehabilitation strategies. This study presents a novel approach to classifying motor tasks using EEG data from acute stroke patients, focusing on left-hand motor imagery, right-hand motor imagery, and rest states. By using advanced source localization techniques, such as Minimum Norm Estimation (MNE), dipole fitting, and beamforming, integrated with a customized Residual Convolutional Neural Network (ResNetCNN) architecture, we achieved superior spatial pattern recognition in EEG data.

Evolution of Reactive Organic Compounds and Their Potential Health Risk in Wildfire Smoke.

Environ Sci Technol

November 2024

NOAA Chemical Sciences Laboratory, Boulder, Colorado 80305, United States.

Article Synopsis
  • Wildfires are a growing contributor to air pollution, particularly due to reactive organic compounds (ROC), which have varying health impacts based on their toxicity and abundance.
  • A study combining field campaign data and air quality modeling found that current emissions estimates capture only 40-45% of the total ROC released from wildfires.
  • The research indicates that particulate ROC could significantly affect health risks from smoke exposure, highlighting the need for more accurate toxicity data on these compounds.
