A multicenter case series of 21 patients were treated with imipenem-cilastatin-relebactam. There were mixed infection sources, with pulmonary infections (11/21,52%) composing the majority. The primary pathogen was Pseudomonas aeruginosa (16/21, 76%), and 15/16 (94%) isolates were multidrug-resistant. Thirty-day survival occurred in 14/21 (67%) patients. Two patients experienced adverse effects.


Cryo-Em Reveals The Architecture Of Placental Malaria Var2csa And Provides Molecular Insight Into Chondroitin Sulfate Binding, Kaituo Wang, Robert Dagil, Thomas Lavstsen, Sandeep K. Misra Dec 2021

Cryo-Em Reveals The Architecture Of Placental Malaria Var2csa And Provides Molecular Insight Into Chondroitin Sulfate Binding, Kaituo Wang, Robert Dagil, Thomas Lavstsen, Sandeep K. Misra

Faculty and Student Publications

Placental malaria can have severe consequences for both mother and child and effective vaccines are lacking. Parasite-infected red blood cells sequester in the placenta through interaction between parasite-expressed protein VAR2CSA and the glycosaminoglycan chondroitin sulfate A (CS) abundantly present in the intervillous space. Here, we report cryo-EM structures of the VAR2CSA ectodomain at up to 3.1 Å resolution revealing an overall V-shaped architecture and a complex domain organization. Notably, the surface displays a single significantly electropositive patch, compatible with binding of negatively charged CS. Using molecular docking and molecular dynamics simulations as well as comparative hydroxyl radical protein foot-printing of …


Identification Of A Solo Acylhomoserine Lactone Synthase From The Myxobacterium Archangium Gephyra, Hanan Albataineh, Maya Duke, Sandeep K. Misra, Joshua S. Sharp Dec 2021

Identification Of A Solo Acylhomoserine Lactone Synthase From The Myxobacterium Archangium Gephyra, Hanan Albataineh, Maya Duke, Sandeep K. Misra, Joshua S. Sharp

Faculty and Student Publications

Considered a key taxon in soil and marine microbial communities, myxobacteria exist as coordinated swarms that utilize a combination of lytic enzymes and specialized metabolites to facilitate predation of microbes. This capacity to produce specialized metabolites and the associated abundance of biosynthetic pathways contained within their genomes have motivated continued drug discovery efforts from myxobacteria. Of all myxobacterial biosynthetic gene clusters deposited in the antiSMASH database, only one putative acylhomoserine lactone (AHL) synthase, agpI, was observed, in genome data from Archangium gephyra. Without an AHL receptor also apparent in the genome of A. gephyra, we sought to determine if AgpI …

Characterization And In Vitro And In Vivo Evaluation Of Tacrolimus-Loaded Poly(Ε-Caprolactone) Nanocapsules For The Management Of Atopic Dermatitis, Guilherme Dos Anjos Camargo, Leandro Ferreira, Diego José Schebelski, Amanda Martinez Lyra

Faculty and Student Publications

Background: Tacrolimus (TAC) is a drug of natural origin used in conventional topical dosage forms to control atopic dermatitis. However, direct application of the drug often causes adverse side effects in some patients. Hence, drug nanoencapsulation could be used as an improved novel therapy to mitigate the adverse effects and enhance bioavailability of the drug. Methods: Physicochemical properties, in vitro drug release experiments, and in vivo anti-inflammatory activity studies were performed. Results: TAC-loaded nanocapsules were successfully prepared by the interfacial deposition of preformed polymer using poly(ε-caprolactone) (PCL). The nanoparticu-late systems presented a spherical shape with a smooth and regular surface, …

The purpose of this study was to determine if a methanolic extract of the Pulsatilla patens (L.) Mill. can inhibit the progression of cancer through the modulation of cancer-related metabolic signaling pathways. We analyzed a panel of 13 inducible luciferase reporter gene vectors which expression is driven by enhancer elements that bind to specific transcription factors for the evaluation of the activity of cancer signaling pathways. The root extract of P. patens exhibited strong inhibition of several signaling pathways in HeLa cells, a cervical cancer cell line, and was found to be the most potent in inhibiting the activation of …


Functional Genomics Study Of Pseudomonas Putida To Determine Traits Associated With Avoidance Of A Myxobacterial Predator, Shukria Akbar, D. Cole Stevens Dec 2021

Functional Genomics Study Of Pseudomonas Putida To Determine Traits Associated With Avoidance Of A Myxobacterial Predator, Shukria Akbar, D. Cole Stevens

Faculty and Student Publications

Predation contributes to the structure and diversity of microbial communities. Predatory myxobacteria are ubiquitous to a variety of microbial habitats and capably consume a broad diversity of microbial prey. Predator–prey experiments utilizing myxobacteria have provided details into predatory mechanisms and features that facilitate consumption of prey. However, prey resistance to myxobacterial predation remains underexplored, and prey resistances have been observed exclusively from predator–prey experiments that included the model myxobacterium Myxococcus xanthus. Utilizing a predator–prey pairing that instead included the myxobacterium, Cystobacter ferrugineus, with Pseudomonas putida as prey, we observed surviving phenotypes capable of eluding predation. Comparative transcriptomics between P. putida …

Transmission Studies And The Composition Of Prokaryotic Communities Associated With Healthy And Diseased Aplysina Cauliformis Sponges Suggest That Aplysina Red Band Syndrome Is A Prokaryotic Polymicrobial Disease, Matteo Monti, Aurora Giorgi, Cole G. Easson, Deborah J. Gochfeld

Faculty and Student Publications

Aplysina cauliformis, the Caribbean purple rope sponge, is commonly affected by Aplysina Red Band Syndrome (ARBS). This transmissible disease manifests as circular lesions with red margins and results in bare spongin fibers. Leptolyngbya spp. appear to be responsible for the characteristic red coloration but transmission studies with a sponge-derived isolate failed to establish disease, leaving the etiology of ARBS unknown. To investigate the cause of ARBS, contact transmission experiments were performed between healthy and diseased sponges separated by filters with varying pore sizes. Transmission occurred when sponges were separated by filters with pore sizes ≥ 2.5 μm, suggesting a prokaryotic …


Using Multiple Mendelian Randomization Approaches And Genetic Correlations To Understand Obesity, Urate, And Gout, Charleen D. Adams, Brian B. Boutwell Dec 2021

Using Multiple Mendelian Randomization Approaches And Genetic Correlations To Understand Obesity, Urate, And Gout, Charleen D. Adams, Brian B. Boutwell

Faculty and Student Publications

Observational studies suggest relationships between obesity, urate, and gout but are possibly confounded. We assessed whether genetically determined obesity, higher urate (and related traits), and gout were causal using multiple Mendelian randomization (MR) approaches and linkage disequilibrium score regression for genetic correlations (rg). For data, we used genome-wide association study summary statistics available through MR-Base. We observed that obesity increased urate (beta = 0.127; 95% CI = 0.098, 0.157; P-value = 1.2E−17; rg = 0.25 [P-value = 0.001]) and triglycerides (beta = 0.082; 95% CI = 0.065, 0.099; P-value = 1.2E−21; rg = 0.23 [P-value = 8.8E−12]) and decreased high-density …

Climate And Seasonality Drive The Richness And Composition Of Tropical Fungal Endophytes At A Landscape Scale, Shuzo Oita, Alicia Ibáñez, François Lutzoni, Jolanta Miadlikowska, József Geml, Louise A. Lewis, Erik F. Y. Hom, Ignazio Carbone, Jana M. U’Ren, A. Elizabeth Arnold

Faculty and Student Publications

Understanding how species-rich communities persist is a foundational question in ecology. In tropical forests, tree diversity is structured by edaphic factors, climate, and biotic interactions, with seasonality playing an essential role at landscape scales: wetter and less seasonal forests typically harbor higher tree diversity than more seasonal forests. We posited that the abiotic factors shaping tree diversity extend to hyperdiverse symbionts in leaves—fungal endophytes—that influence plant health, function, and resilience to stress. Through surveys in forests across Panama that considered climate, seasonality, and covarying biotic factors, we demonstrate that endophyte richness varies negatively with temperature seasonality. Endophyte community structure and …

Through analysis of a difference in differences regression, this research demonstrates that the policy had no effect on sex violence in Northern Ireland. Scotland and Ireland proved to be better control groups for Northern Ireland in terms of the identifying assumptions …


A Case For The Decriminalization Of Simple Possession Of Narcotics In Mississippi, Stroud Tolleson Dec 2021

A Case For The Decriminalization Of Simple Possession Of Narcotics In Mississippi, Stroud Tolleson

Honors Theses

Through its incarceration of simple possession offenders, Mississippi is failing to acknowledge the severity of addiction and importance of mental health. In this paper, I will examine Mississippi’s history of opinion and policy on drug use. In order to gain a better understanding of addiction and Mississippi’s criminal justice system, I interview several individuals with experience in varying aspects of these issues. Mississippi has one of the highest rates of incarceration in the United States, with stringent laws regarding the possession of narcotics. Mississippi’s mental health resources have been deemed unconstitutionally deficient on more than one occasion, and addicts are …

Mutants Of The White Abcg Transporter In Drosophila Melanogaster Have Deficient Olfactory Learning And Cholesterol Homeostasis, Jennifer L. Myers, Maria Porter, Nicholas Narwold, Krishna Bhat, Brigitte Dauwalder, Gregg Roman

Faculty and Student Publications

Drosophila’s white gene encodes an ATP binding cassette G-subfamily (ABCG) half transporter. White is closely related to mammalian ABCG family members that function in cholesterol efflux. Mutants of white have several behavioral phenotypes that are independent of visual defects. This study characterizes a novel defect of white mutants in the acquisition of olfactory memory using the aversive olfactory conditioning paradigm. The w1118 mutants learned slower than wildtype controls, yet with additional training, they reached wildtype levels of performance. The w1118 learning phenotype is also found in the wapricot and wcoral alleles, is dominant, and is …

Insulin-Like Growth Factor-1 Differentially Modulates Glutamate-Induced Toxicity And Stress In Cells Of The Neurogliovascular Unit, Cellas A. Hayes, Brandon G. Ashmore, Akshaya Vijayasankar, Jessica P. Marshall

Faculty and Student Publications

The age-related reduction in circulating levels of insulin-like growth factor-1 (IGF-1) is associated with increased risk of stroke and neurodegenerative diseases in advanced age. Numerous reports highlight behavioral and physiological deficits in blood-brain barrier function and neurovascular communication when IGF-1 levels are low. Administration of exogenous IGF-1 reduces the extent of tissue damage and sensorimotor deficits in animal models of ischemic stroke, highlighting the critical role of IGF-1 as a regulator of neurovascular health. The beneficial effects of IGF-1 in the nervous system are often attributed to direct actions on neurons; however, glial cells and the cerebrovasculature are also modulated …
