Hepatocytes represent an important target for gene therapy and editing of single-gene disorders. In alpha-1 antitrypsin (AAT) deficiency, one missense mutation results in impaired secretion of AAT. In most patients, lung damage occurs due to a lack of AAT-mediated protection of lung elastin from neutrophil elastase. In some patients, accumulation of misfolded PiZ mutant AAT protein triggers hepatocyte injury, leading to inflammation and cirrhosis. We hypothesized that correcting the Z mutant defect in hepatocytes would confer a selective advantage for repopulation of hepatocytes within an intact liver. A human PiZ allele was crossed onto an immune-deficient (NSG) strain to create …
Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy
Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy
University of New Orleans Theses and Dissertations
The model of basal ganglia function proposed by Albin, Young and Penney (1989) describes two anatomically independent motor pathways, the direct and indirect. However, under normal conditions striatal dopamine (DA) is required for the expression of motor behavior, and DAergic control of the two pathways (via D1 and D2 receptors, respectively) is dependent on co-activation. We tested for a possible breakdown of D1/D2 synergism using transgenic R6/1 mice bearing the human huntingtin allele (Htt). Motor stereotypy, observed prior to the onset of HD-related symptoms, was rated on a 5-point scale following activation of: A) D1 receptors alone, B) D2 receptors …
Interventions To Reduce Neonatal Mortality From Neonatal Tetanus In Low And Middle Income Countries - A Systematic Review, Adeel Ahmed Khan, Aysha Zahidie, F. Rabbani
Interventions To Reduce Neonatal Mortality From Neonatal Tetanus In Low And Middle Income Countries - A Systematic Review, Adeel Ahmed Khan, Aysha Zahidie, F. Rabbani

Background In 1988, WHO estimated around 787,000 newborns deaths due to neonatal tetanus. Despite few success stories majority of the Low and Middle Income Countries (LMICs) are still struggling to reduce neonatal mortality due to neonatal tetanus. We conducted a systematic review to understand the interventions that have had a substantial effect on reducing neonatal mortality rate due to neonatal tetanus in LMICs and come up with feasible recommendations for decreasing neonatal tetanus in the Pakistani setting. Methods We systemically reviewed the published literature (Pubmed and Pubget databases) to identify appropriate interventions for reducing tetanus related neonatal mortality. A total …
Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte
Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte
University Scholar Projects
Sickle cell disease (SCD) has been shown to be associated with decreased baseline immunity and thus increased susceptibility to infection. I sought to discern possible causes of this by looking into the correlations between SCD and hematopoiesis, the immune system and the neuroendocrine system, and ultimately by conducting experiments surrounding the impaired immune system of SCD. These experiments focused on the potential causes and effects of the diminution of B-1a cells in the SCD spleen. Adoptive transfers, infections with Streptococcus pneumoniae, and histologic imaging were conducted to establish if the diminution of the B-1a cells in the SCD spleen …
Persistent Neurobehavioral Traits In A Mouse Model Of Prenatal Ethanol Exposure, Jill M. Lawrence
Persistent Neurobehavioral Traits In A Mouse Model Of Prenatal Ethanol Exposure, Jill M. Lawrence
Neuroscience Honors Papers
Fetal Alcohol Spectrum Disorders (FASD) effect an estimated 2% of the population, causing a range of symptoms: from craniofacial defects to inhibited cortical growth (May, et al., 2009; Murawski, et al., 2015). Impaired medial forebrain function apparent in FASD is associated with lifelong cognitive behavioral deficits, but these consequences may be avoided with early diagnosis and intervention (Streissguth, et al., 2004). Our goal is to identify early neurobehavioral abnormalities that persist into adulthood that could potentially serve as early indicators for FASD. Mouse models of prenatal ethanol exposure were developed using a voluntary drinking paradigm that introduced a sweetened ethanol …

BACKGROUND: Refractory esophageal stricture (RES) may be attributed to food allergy. Its etiology and pathogenesis are not fully understood. Identification of novel genetic variants associated with this disease by exome sequencing (exome-seq) may provide new mechanistic insights and new therapeutic targets.
METHODS: To identify new and novel disease-associating variants, whole-exome sequencing was performed on an Illumina NGS platform in three children with RES as well as food allergy.
RESULTS: A total of 91,024 variants were identified. By filtering out 'normal variants' against those of the 1000 Genomes Project, we identified 12,741 remaining variants which are potentially associated with RES plus …

BACKGROUND: The DiGeorge syndrome, the most common of the microdeletion syndromes, affects multiple organs, including the heart, the nervous system, and the kidney. It is caused by deletions on chromosome 22q11.2; the genetic driver of the kidney defects is unknown.
METHODS: We conducted a genomewide search for structural variants in two cohorts: 2080 patients with congenital kidney and urinary tract anomalies and 22,094 controls. We performed exome and targeted resequencing in samples obtained from 586 additional patients with congenital kidney anomalies. We also carried out functional studies using zebrafish and mice.
RESULTS: We identified heterozygous deletions of 22q11.2 in 1.1% …

Drug-resistant epilepsy poses a challenge in neonatal patients, especially those in the neonatal intensive care unit (NICU), who have various secondary comorbidities. We present results of four children with a history of drug-resistant epilepsy for whom a ketogenic diet was initiated and used in the NICU. A nonfasting induction into ketosis over 1-2 weeks was utilized, with gradual increases in the ketogenic ratio every 2-3 days. Data were collected retrospectively from a database, which included medical history, daily progress notes, relevant laboratory data, and imaging and diagnostic information. The ketogenic diet was well tolerated in all cases. The most common …

Some pregnancies today involve infertile individuals or couples who contract with a fertile woman to carry a pregnancy for them. The woman who carries the pregnancy is referred to as a "gestational carrier." The use of such arrangements is increasing. Most of the time, these arrangements play out as planned; sometimes, however, problems arise. This article discusses a case in which a fetal diagnosis of spina bifida led the infertile couple to request that the gestational carrier terminate the pregnancy, and the gestational carrier did not wish to do so. Experts in the medical and legal issues surrounding surrogacy discuss …
Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts
Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts
Williams Honors College, Honors Research Projects
Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.
Objectives: To evaluate the use of biomarkers in children seen in the Emergency …

Activated PI3K-δ syndrome refers to a recently described primary immunodeficiency syndrome consisting of recurrent sinopulmonary infections, lymphadenopathy, mucosal lymphoid aggregates, increased susceptibility to Epstein-Barr virus and cytomegalovirus, and increased incidence of B-cell lymphomas. Variants in PIK3CD, which encodes the phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta isoform, enhance membrane association and kinase activity, resulting in increased signal transduction through the PI3K-Akt pathway. Whole-exome sequencing revealed a pathogenic PIK3CD variant in a patient with history of immunologic impairment, recurrent sinopulmonary infections, and lymphoid hyperplasia presenting as intussusception. This case illustrates that while lymphoid hyperplasia secondary to immunodeficiency is most often unsurprising and …
