Department of Environmental and Occupational Health, University of California, Irvine, CA, USA; Department of Statistics, University of California, Irvine, CA, USA; Department of Epidemiology and Biostatistics, University of California, Irvine, CA, USA.

Article Synopsis
  • The study investigates PFAS exposure rates during pregnancy, focusing on ingestion of food and indoor dust as primary sources.
  • It uses published dietary intake estimates and a pharmacokinetic model to predict serum concentrations of PFAS in pregnant women, comparing these predictions with actual measured levels.
  • Results suggest that lower dietary intake estimates effectively predict maternal serum PFAS concentrations, while higher estimates tend to overestimate levels, indicating that careful selection of intake data is crucial for accurate predictions.

A Splice Site Variant in SENP7 Results in a Severe Form of Arthrogryposis.

Clin Genet

January 2025

Division of Genetics, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Arthrogryposis multiplex congenita (AMC) is a heterogeneous disorder associated with 1/3000 to 1/5000 live births. We report a consanguineous family with multiple affected members with AMC and identified a recessive mutation in the highly conserved splice donor site, resulting in the mis-splicing of the affected exons. SENP7 is a deSUMOylase that is critical for sarcomere assembly and skeletal muscle contraction by regulating the transcriptional program in the skeletal muscle.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Self-organization under out-of-equilibrium conditions is ubiquitous in natural systems for the generation of hierarchical solid-state patterns of complex structures with intricate properties. Efforts in applying this strategy to synthetic materials that mimic biological function have resulted in remarkable demonstrations of programmable self-healing and adaptive materials. However, the extension of these efforts to multifunctional stimuli-responsive solid-state materials across defined spatial distributions remains an unrealized technological opportunity.

Despite the extensive use of network autocorrelation models in social network analysis, network autocorrelation models for binary dependent variables have received surprisingly scant attention. In this paper, we develop four network autocorrelation models for a binary random variable defined by whether the peer effect (also termed social influence or contagion) acts on latent continuous outcomes leading to an indirect effect under a normal or a logistic distribution or on the probability of the observed outcome itself under a probit or a logit link function defining a direct effect to account for interdependence between outcomes. For all models, we use a Bayesian approach for model estimation under a uniform prior on a transformed peer effect parameter ( ) designed to enhance model computation and compare results to those under the uniform prior for .

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a leading pathogen causing severe endovascular infections. The prophage-encoded protein Gp05 has been identified as a critical virulence factor that contributes to MRSA persistence during vancomycin (VAN) treatment in an experimental endocarditis model. However, the underlining mechanisms driving this persistence phenotype remain poorly understood.

Mast seeding, the synchronous and highly variable production of seed crops by perennial plants, is a population-level phenomenon and has cascading effects in ecosystems. Mast seeding studies are typically conducted at the population/species level. Much less is known about synchrony in mast seeding between species because the necessary long-term data are rarely available.

Relations among territoriality, abundance and habitat suitability are fundamental to the ecology of many animal populations. Theory suggests two classes of possible responses to increasing abundance in territorial species: (1) the ideal free distribution (IFD), which predicts smaller territory sizes and decreased fitness as individuals adaptively pack into suitable habitats, and (2) the ideal despotic distribution (IDD), which predicts stable territory sizes and fitness in preferred habitats for dominant individuals and increased use of marginal habitats, reduced fitness and changes in territory sizes for subordinate individuals. We analysed the territory sizes and locations of seven migratory songbird species occupying a 10-ha plot in the Hubbard Brook Experimental Forest, New Hampshire, USA over a 52-year period.

The computational study of ligand binding to a target protein provides mechanistic insight into the molecular determinants of this process and can improve the success rate of drug design. All-atom molecular dynamics (MD) simulations can be used to evaluate the binding free energy, typically by thermodynamic integration, and to probe binding mechanisms, including the description of protein conformational dynamics. The advantages of MD come at a high computational cost, which limits its use.
