We discuss the potential usefulness of molecular testing of soil, dust, and water samples to detect medically important parasites, and where such testing could be used to supplement stool sampling in humans. A wide variety of parasites including protozoa and helminths, many of which are zoonotic, have an important infection reservoir in the environment. In some cases, this environmental period is essential for further parasite development. We describe the progress in implementing methods for the molecular detection of these parasites in soil across eight collaborating centers in Latin America and represent a variety of potential applications in improving our understanding …

Untargeted Metabolomic Biomarker Discovery For The Detection Of Ectopic Pregnancy, Onur Turkoglu, Ayse Citil, Ceren Katar, Ismail Mert, Robert A Quinn, Ray O Bahado-Singh, Stewart F Graham

Faculty, Staff and Students Publications

Ectopic pregnancy (EP) is the leading cause of maternal morbidity and mortality in the first trimester. Using an untargeted metabolomic approach, we sought to identify putative plasma biomarkers using tandem liquid chromatography-mass spectrometry for the detection of tubal EP. This case-control study included the prospective recruitment of 50 tubal EP cases and 50 early intrauterine pregnancy controls. To avoid over-fitting, logistic regression models were developed in a randomly selected discovery group (30 cases vs. 30 controls) and validated in the test group (20 cases vs. 20 controls). In total, 585 mass spectral features were detected, of which 221 molecular features …

Surgical Technique For Glenoid Bone Defect In Revision Shoulder Arthroplasty: Distal Clavicle Excision And Grafting For 1-Stage Reverse Total Shoulder Prosthesis, Ryan Bialaszewski, Ross Chapel, Frank Gerold

Research Colloquium

Introduction: Reverse shoulder arthroplasty (RSA) has expanded its indications and use in North America since the early 1990s. Because of this, the prevalence of revision reverse total shoulder arthroplasty cases has continued to rise. On occasion, the need for revision of RSA can be due to and is complicated by glenoid bone loss defects, making this one of the most challenging cases for arthroplasty surgeons to perform. Historically, iliac crest or tibial grafts are most commonly used for these defects, although this comes with the disadvantage of requiring two surgical sites to be prepped and draped. The purpose of this …

Does Bimodal Stimulation Improve Or Interfere With Consonant Perception?, Courtney J. Austin, Rose Dumont, Alexander Kain, Holden Sanders, Lina Reiss

Research Colloquium

Bimodal stimulation, the usage of both a cochlear implant and a hearing aid in the contralateral ear, is noted for improving speech perception in noisy backgrounds for some hearing-impaired individuals. However, the usage of both devices provides a range of variability in benefit that relate to difference in pitch fusion range. Hearing impaired populations are noted to have broad binaural fusion ranges compared to normal hearing population, effecting the ability to perceive certain syllables. In studies involving vowels classification and fusion, bimodal CI users showed significant difference in both CI-only conditions and HA-only conditions, compared to the bimodal conditions (Reiss …

An Approach To Analyze Spatiotemporal Patterns Of Gene Expression At Single-Cell Resolution In Candida Albicans-Infected Mouse Tongues, Elena Lindemann-Perez, Diana L Rodríguez, J Christian Pérez

Faculty, Staff and Student Publications

Microbial gene expression measurements derived from infected organs are invaluable to understand pathogenesis. However, current methods are limited to "bulk" analyses that neglect microbial cell heterogeneity and the lesion's spatial architecture. Here, we report the use of hybridization chain reaction RNA fluorescence in situ hybridization (HCR RNA-FISH) to visualize and quantify Candida albicans transcripts at single-cell resolution in tongues of infected mice. The method is compatible with fixed-frozen and formalin-fixed paraffin-embedded tissues. We document cell-to-cell variation and intriguing spatiotemporal expression patterns for C. albicans mRNAs that encode products implicated in oral candidiasis. The approach provides a spatial dimension to gene …

Dense And Persistent Odor Representations In The Olfactory Bulb Of Awake Mice, Delaram Pirhayati, Cameron L Smith, Ryan Kroeger, Saket Navlakha, Paul Pfaffinger, Jacob Reimer, Benjamin R Arenkiel, Ankit Patel, Elizabeth H Moss

Children’s Nutrition Research Center Staff Publications

Recording and analysis of neural activity are often biased toward detecting sparse subsets of highly active neurons, masking important signals carried in low-magnitude and variable responses. To investigate the contribution of seemingly noisy activity to odor encoding, we used mesoscale calcium imaging from mice of both sexes to record odor responses from the dorsal surface of bilateral olfactory bulbs (OBs). The outer layer of the mouse OB is comprised of dendrites organized into discrete "glomeruli," which are defined by odor receptor-specific sensory neuron input. We extracted activity from a large population of glomeruli and used logistic regression to classify odors …

Neuroimmune interactions are essential for the development of neuropathic pain, yet the contributions of distinct immune cell populations have not been fully unraveled. Here, we demonstrate the critical role of B cells in promoting mechanical hypersensitivity (allodynia) after peripheral nerve injury in male and female mice. Depletion of B cells with a single injection of anti-CD20 monoclonal antibody at the time of injury prevented the development of allodynia. B cell-deficient (muMT) mice were similarly spared from allodynia. Nerve injury was associated with increased immunoglobulin G (IgG) accumulation in ipsilateral lumbar dorsal root ganglia (DRGs) and dorsal spinal cords. IgG was …

Faculty, Staff and Students Publications

Many Parkinson’s disease (PD) models overexpress α-Synuclein using heterologous promoters, which is adequate to demonstrate that excessive α-Synuclein is toxic but not ideal for learning the precise ontogeny of the disease pathogenesis, specifically where the disease starts and how it progresses. To answer these questions, it is beneficial to generate a mouse model expressing a disease-causing mutation under the endogenous promoter. Here, we generated three Snca knock-in mice. Among them, homozygous Snca^G51D mice develop motor deficits by 9 mo of age. These mice exhibit olfactory and gastrointestinal abnormalities by 6 mo. They lose dopaminergic neurons and have reduced dopamine …

Effective psychotherapy of post-traumatic stress disorder (PTSD) remains challenging owing to the fragile nature of fear extinction, for which the ventral hippocampal CA1 (vCA1) region is considered as a central hub. However, neither the core pathway nor the cellular mechanisms involved in implementing extinction are known. Here, we unveil a direct pathway, where layer 2a fan cells in the lateral entorhinal cortex (LEC) target parvalbumin-expressing interneurons (PV-INs) in the vCA1 region to propel low-gamma-band synchronization of the LEC-vCA1 activity during extinction learning. Bidirectional manipulations of either hippocampal PV-INs or LEC fan cells sufficed for fear extinction. Gamma entrainment of vCA1 …

Understanding the mechanisms underlying immune evasion is crucial for developing novel anticancer modalities. To systematically uncover tumor-intrinsic genetic modulators involved in immune escape in tumor microenvironment, we performed genome-scale in vivo CRISPR screens in two syngeneic models and later expanded up to seven syngeneic models with a focused validation library. These data help us better understand tumor immune evasion and pave the way for developing effective therapeutics. Importantly, we uncovered that Mga depletion elicited an antitumor immune response and inhibited tumor growth in triple-negative breast cancer. Our findings suggest that Mga may play a role in modulating the tumor immune …

Arousal and motivation interact to profoundly influence behavior. For example, experience tells us that we have some capacity to control our arousal when appropriately motivated, such as staying awake while driving a motor vehicle. However, little is known about how arousal and motivation jointly influence decision computations, including if and how animals, such as rodents, adapt their arousal state to their needs. Here, we developed and show results from an auditory, feature-based, sustained-attention task with intermittently shifting task utility. We use pupil size to estimate arousal across a wide range of states and apply tailored signal detection theoretic, hazard function …
