Frontal Alpha Asymmetry And Inhibitory Control Among Individuals With Cannabis Use Disorders, Alina Shevorykin, Lesia M. Ruglass, Robert D. Melara

Publications and Research

To better understand the biopsychosocial mechanisms associated with development and maintenance of cannabis use disorder (CUD), we examined frontal alpha asymmetry (FAA) as a measure of approach bias and inhibitory control in cannabis users versus healthy nonusers. We investigated: (1) whether FAA could distinguish cannabis users from healthy controls; (2) whether there are cue-specific FAA effects in cannabis users versus controls; and (3) the time course of cue-specific approach motivation and inhibitory control processes. EEG data were analyzed from forty participants (CUD (n = 20) and controls (n = 20)) who completed a modified visual attention task. Results showed controls …

The microbial communities that inhabit the distal gut of humans and other mammals exhibit large inter-individual variation. While host genetics is a known factor that influences gut microbiota composition, the mechanisms underlying this variation remain largely unknown. Bile acids (BAs) are hormones that are produced by the host and chemically modified by gut bacteria. BAs serve as environmental cues and nutrients to microbes, but they can also have antibacterial effects. We hypothesized that host genetic variation in BA metabolism and homeostasis influence gut microbiota composition. To address this, we used the Diversity Outbred (DO) stock, a population of genetically distinct …

Direct Measurement Of Performance: A New Era In Antimicrobial Stewardship, Majdi N. Al-Hasan, Hana Rac Winders, P. Brandon Bookstaver, Julie Ann Justo

Faculty Publications

Penicillin allergies are among of the most commonly reported allergies, yet only 10% of these patients are truly allergic. This leads to potential inadvertent negative consequences for patients and makes treatment decisions challenging for clinicians. Thus, allergy assessment and penicillin skin testing (PST) are important management strategies to reconcile and clarify labeled penicillin allergies. While PST is more common in the inpatient setting where the results will immediately impact antibiotic management, this process is becoming of increasing importance in the outpatient setting. PST in the outpatient setting allows clinicians to proactively de-label and educate patients accordingly so beta-lactam antibiotics may …

Influence Of Sport Specialization On Athletic Performance And Injury Risk In Collegiate Swimmers, Samantha M. Gunn, Gerald T. Mangine, Trisha A. Vandusseldorp, Garrett M. Hester

The Kennesaw Journal of Undergraduate Research

To assess the effect of swimming specialization on performance and injury risk in collegiate swimmers, thirty collegiate swimmers (20.1 ± 0.9 years [18.5 – 22.3 years]) were asked to complete an anonymous survey to provide information regarding their sports participation history, success in swimming, and the occurrence and quantity of swimming-related injuries. Specialization status was determined by the swimmer claiming they had specialized and by the number of months (≥ 8 months) they participated in swimming each year. Correlation analysis revealed several significant (p < 0.05) relationships between all determinants of specialization, swimming success, and swimming injuries. Stepwise regression analysis revealed that the age which an athlete specialized was the best predictor of the occurrence of a swimming- related injury (R² = 0.34, p = 0.004) and the number of injuries sustained (R² = 0.25, …

Liver-X-receptor (LXR) agonists are known to bear anti-tumor activity. However, their efficacy is limited and additional insights regarding the underlying mechanism are necessary. By performing transcriptome analysis coupled with global polar metabolite screening, we show that LXR agonists, LXR623 and GW3965, enhance synergistically the anti-proliferative effect of BH3 mimetics in solid tumor malignancies, which is predominantly mediated by cell death with features of apoptosis and is rescued by exogenous cholesterol. Extracellular flux analysis and carbon tracing experiments (U-¹³C-glucose and U-¹³C-glutamine) reveal that within 5 h, activation of LXRβ results in reprogramming of tumor cell metabolism, leading …

School of Medicine Publications

Maternal separation (MS) early in life is related to an increase in anxiety and depressive-like behaviors and neurobiological alterations mostly related to alterations in hypothalamic pituitary adrenal (HPA) axis reactivity. Environmental enrichment (EE) has been used to ameliorate the effects of MS. However, the outcomes of this intervention at different developmental periods after MS have not been studied. We subjected male and female Sprague-Dawley pups to MS and subsequently compared the effects of EE started either in the pre-pubertal period [postnatal day (PND) 22] or adulthood (PND 78). Anxiety and depressive-like behaviors as well as in hippocampal synaptic density and …

Internal Medicine

Background: Duodenal variceal bleeding is a rare cause of gastrointestinal bleeding. The most common site is the duodenal bulb. It is usually detected endoscopically but it can be very challenging to diagnose if it is located distal to the second part of duodenum. The pre- transjugular intrahepatic portosystemic shunt (TIPS) presence of SPSS was found to be associated with an increased risk of early morbidity and mortality after TIPS placement. Case Summary: A 43-year-old cirrhotic male presented with melena for three days. Upper endoscopy was performed and showed active blood oozing from the distal duodenum concerning for ectopic duodenal varix. …

Binding During Sequence Learning Does Not Alter Cortical Representations Of Individual Actions, Patrick Beukema, Jörn Diedrichsen, Timothy D. Verstynen

Brain and Mind Institute Researchers' Publications

Copyright © 2019 the authors. As a sequence of movements is learned, serially ordered actions get bound together into sets to reduce computational complexity during planning and execution. Here, we investigated how actions become naturally bound over the course of learning and how this learning affects cortical representations of individual actions. Across 5 weeks of practice, neurologically healthy human subjects learned either a complex 32-item sequence of finger movements (trained group, n = 9; 3 female) or randomly ordered actions (control group, n = 9; 3 female). Over the course of practice, responses during sequence production in the trained group …

Operative Versus Conservative Treatment Of Clavicular And Scapular Fractures, Chase Davis

Theses and Graduate Projects

Background: Clavicle fractures and scapula fractures represent up to 4% and 1% of all fractures, respectively.^1-4,9-11 Historically, both fracture types have been treated conservatively with acceptable outcomes. The surgical correction of these fractures is currently being investigated as a viable alternative to conservative management.

Method: A systematic search of PubMed was performed to identify articles comparing open reduction and internal fixation (ORIF) with conservative treatment for both clavicular and scapular fractures. Specific outcomes of interest were shoulder function, pain, strength, range of motion, and risk of nonunion.

Results: ORIF of midshaft clavicular fractures results in increased shoulder function within …

Modeling Interval Timing By Recurrent Neural Nets, Theodore Raphan, Eugene Dorokhin, Andrew R. Delamater

Publications and Research

The purpose of this study was to take a new approach in showing how the central nervous system might encode time at the supra-second level using recurrent neural nets (RNNs). This approach utilizes units with a delayed feedback, whose feedback weight determines the temporal properties of specific neurons in the network architecture. When these feedback neurons are coupled, they form a multilayered dynamical system that can be used to model temporal responses to steps of input in multidimensional systems. The timing network was implemented using separate recurrent “Go” and “NoGo” neural processing units to process an individual stimulus indicating the …

Spontaneous Mutations Of The Zpld1 Gene In Mice Cause Semicircular Canal Dysfunction But Do Not Impair Gravity Receptor Or Hearing Functions., Sarath Vijayakumar, Sherri M Jones, Timothy A Jones, Cong Tian, Kenneth R. Johnson

Faculty Research 2019

The cupula is a gelatinous membrane overlying the crista ampullaris of the semicircular canal, important for sensing rotation of the head and critical for normal balance. Recently the zona pellucida like domain containing 1 protein (ZPLD1, also known as cupulin) was identified in the cupula of fish. Here, we describe two new spontaneous mutations in the mouse Zpld1 gene, which were discovered by the circling behavior of mutant mice, an indicator of balance dysfunction. The Zpld1 mutant mice exhibited normal hearing function as assessed by auditory brainstem response (ABR) measurements, and their otolithic organs appeared normal. In the inner ear, …

Faculty Research, Scholarly, and Creative Activity

The quantity and quality of child-directed speech—language nutrition—provided to typically-developing children is associated with language outcomes—language health. Limited information is available about child-directed speech to children at biological risk of language impairments. We conducted a scoping review on caregiver child-directed speech for children with three clinical conditions associated with language impairments—preterm birth, intellectual disability, and autism—addressing three questions: (1) How does child-directed speech to these children differ from speech to typically-developing children? (2) What are the associations between child-directed speech and child language outcomes? (3) How convincing are intervention studies that aim to improve child-directed speech and thereby facilitate children’s …
