Study Objectives: Evaluate the performance of the SANSA device to simultaneously assess obstructive sleep apnea (OSA) and cardiac arrhythmias.

Methods: Participants suspected or known to have OSA underwent polysomnography (PSG) while wearing SANSA. SANSA's algorithm was trained using 86 records and tested on 67 to evaluate training bias.

Background: Intravoxel incoherent motion (IVIM) MRI uses diffusion-weighted (DW) MRI acquisitions to evaluate the microvascular and cellular environments of tissue. Due to these properties, IVIM has been increasingly utilized to evaluate abnormal placentation.

Objective: Our primary objective was to compare IVIM parameters in the placenta of patients with fetal growth restriction and appropriate for gestational age controls across gestational ages.

The overall goal of this research was to develop an embryonic stem cell (ESC) line from the Pacific white shrimp, Litopenaeus vannamei, to support production of cell-based cultivated seafood products towards meeting a growing global demand for sustainable seafood. It was hypothesized that characteristics of ESCs, such as high proliferation and pluripotency, would facilitate development of a continuous cell line that could be triggered to differentiate into a muscle cell phenotype. The targeted approach was based on collection of ESCs from fertilized shrimp eggs at the blastomere stage.

Beta-frequency oscillations (20-30 Hz) are prominent in both human and rodent electroencephalogram (EEG) recordings. Discrete epochs of beta (or Beta2) oscillations are prevalent in the hippocampus and other brain areas during exploration of novel environments. However, little is known about the spatial distribution and temporal relationships of beta oscillations across the cortex in response to novel contexts.
