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.

GnRH-Gonadotropes Interactions Revealed by Pituitary Single-cell Transcriptomics in Zebrafish.

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.

Article Synopsis
  • * The study highlights that natural regeneration of forests is more efficient and less costly than tree planting in degraded areas, analyzing the spatial distribution of natural forests from 2000 to 2016 to identify potential for regeneration.
  • * It estimates that around 215 million hectares, mainly in countries like Brazil, Indonesia, China, Mexico, and Colombia, could naturally regenerate, potentially sequestering 23.4 billion tons of carbon over 30 years—emphasizing the importance of targeting these areas for effective restoration efforts.

Polymicrobial communities are often recalcitrant to antibiotic treatment because interactions between different microbes can dramatically alter their responses and susceptibility to antimicrobials. However, the mechanisms of evolving antimicrobial resistance in such polymicrobial environments are poorly understood. We previously reported that Mg depletion caused by the fungus can enable to acquire significant resistance to colistin, a last-resort antibiotic targeting bacterial membrane.

Temporal trends demonstrate improved survival for many types of common pediatric cancer. Studies have not examined improvement in very rare pediatric cancers or compared these improvements to more common cancers. In this cohort study of the Surveillance, Epidemiology, and End Results (SEER) registry, we examined patients from 1975 to 2016 who were 0-19 years of age at the time of diagnosis.

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.

Thiophene and two derivatives (2-methylthiophene and 3-methylthiophene) have been detected on the surface of Mars with the Sample Analysis at Mars instrument suite onboard NASA's Curiosity rover. Thiophene could serve as a secondary chemical biosignature since the secondary biosynthesis of thiophene is considered an important production pathway. However, it is critical to understand the abiotic formation and destruction of thiophene and its derivatives since these pathways could affect the molecules' stabilities on planetary surfaces over geological timescales.
