Visual-Spatial & Visual-Motor Function In Pediatric Heart Transplant Recipients, Stephanine Dianne Griffone

Loma Linda University Electronic Theses, Dissertations & Projects

Heart surgery is commonly used to repair congenital heart defects and to perform heart transplantation. The associated hypoxia before or during the surgery may cause damage in the parasaggital area of the cerebral cortex, with resulting difficulty during tasks requiring visual-spatial and visual-motor skills. This study compares the performance of children who received a heart transplant during infancy to that of nonclinical children with no medical complications on three visual-motor measures, three visual-spatial measures, and two computerized visual-spatial tasks - a Block Design Matching task and a Mental Rotation task. The children who received a heart transplant achieved significantly lower …

Functional Analysis Of The Amine Substrate Specificity Domain Of Pepper Tyramine And Serotonin N-Hydroxycinnamoyltransferases, Sei Kang, Kiyoon Kang, Gap Chae Chung, Doil Choi, Atsushi Ishihara, Dong-Sun Lee, Kyoungwhan Back

Faculty, Staff and Student Publications

Pepper (Capsicum annuum) serotonin N-hydroxycinnamoyltransferase (SHT) catalyzes the synthesis of N-hydroxycinnamic acid amides of serotonin, including feruloylserotonin and p-coumaroylserotonin. To elucidate the domain or the key amino acid that determines the amine substrate specificity, we isolated a tyramine N-hydroxycinnamoyltransferase (THT) gene from pepper. Purified recombinant THT protein catalyzed the synthesis of N-hydroxycinnamic acid amides of tyramine, including feruloyltyramine and p-coumaroyltyramine, but did not accept serotonin as a substrate. Both the SHT and THT mRNAs were found to be expressed constitutively in all pepper organs. Pepper SHT and THT, which have primary sequences that are 78% identical, were used as models …

Translational Regulation Of Nuclear Gene Cox4 Expression By Mitochondrial Content Of Phosphatidylglycerol And Cardiolipin In Saccharomyces Cerevisiae, Xuefeng Su, William Dowhan

Faculty, Staff and Student Publications

Previous results indicated that translation of four mitochondrion-encoded genes and one nucleus-encoded gene (COX4) is repressed in mutants (pgs1Delta) of Saccharomyces cerevisiae lacking phosphatidylglycerol and cardiolipin. COX4 translation was studied here using a mitochondrially targeted green fluorescence protein (mtGFP) fused to the COX4 promoter and its 5' and 3' untranslated regions (UTRs). Lack of mtGFP expression independent of carbon source and strain background was established to be at the translational level. The translational defect was not due to deficiency of mitochondrial respiratory function but was rather caused directly by the lack of phosphatidylglycerol and cardiolipin in mitochondrial membranes. Reintroduction of …

Reproductive Health Update Trainings For Health Workers In North Eastern Province, Garissa, Kenya Ministry Of Health, Population Council

Reproductive Health

The Somali community living in Kenya has practiced the severest form of female genital mutilation/cutting (FGM/C), infibulation, for centuries. To understand the context within which the practice takes place, and how its complications are managed, FRONTIERS undertook a diagnostic study in North Eastern Province and in the Eastleigh area of Nairobi. The study found that the health system is ill equipped to serve women who have been cut, and particularly infibulated women who are pregnant and delivering, stemming from an overall weakness in the availability and quality of maternal and neonatal heath services. Specific recommendations could strengthen these services so …

Strategies For Encouraging The Abandonment Of Female Genital Cutting In West Africa: Experiences From Senegal, Burkina Faso, And Mali, Nafissatou J. Diop, Ian Askew

Reproductive Health

This article explores efforts to encourage abandonment of female genital cutting (FGC) in Senegal, Burkina Faso, and Mali. The strategy of encouraging traditional practitioners to stop performing FGC is not effective as community-level support for the practice remains high. Training health staff significantly improved healthcare providers' levels of knowledge about FGC and its complications. Consequently, it was recommended that such training be incorporated into preservice medical training. The use of community-based strategies like the Village Education Program (VEP) showed the most promise, as their multifaceted approach addresses knowledge, attitudes, actions, and communal support in an integrated manner. The way forward …

Construction Of Improved Temperature-Sensitive And Mobilizable Vectors And Their Use For Constructing Mutations In The Adhesin-Encoding Acm Gene Of Poorly Transformable Clinical Enterococcus Faecium Strains, Sreedhar R Nallapareddy, Kavindra V Singh, Barbara E Murray

Faculty, Staff and Student Publications

Inactivation by allelic exchange in clinical isolates of the emerging nosocomial pathogen Enterococcus faecium has been hindered by lack of efficient tools, and, in this study, transformation of clinical isolates was found to be particularly problematic. For this reason, a vector for allelic replacement (pTEX5500ts) was constructed that includes (i) the pWV01-based gram-positive repAts replication region, which is known to confer a high degree of temperature intolerance, (ii) Escherichia coli oriR from pUC18, (iii) two extended multiple-cloning sites located upstream and downstream of one of the marker genes for efficient cloning of flanking regions for double-crossover mutagenesis, (iv) transcriptional terminator …

Chronic Exposure To Mdma (Ecstasy) Elicits Behavioral Sensitization In Rats But Fails To Induce Cross-Sensitization To Other Psychostimulants, Gunjan M Modi, Pamela B Yang, Alan C Swann, Nachum Dafny

Faculty, Staff and Student Publications

BACKGROUND: The recreational use of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) among adolescents and young adults has become increasingly prevalent in recent years. While evidence suggests that the long-term consequences of MDMA use include neurodegeneration to serotonergic and, possibly, dopaminergic pathways, little is known about susceptibility, such as behavioral sensitization, to MDMA.

METHODS: The objectives of this study were to examine the dose-response characteristics of acute and chronic MDMA administration in rats and to determine whether MDMA elicits behavioral sensitization and whether it cross-sensitizes with amphetamine and methylphenidate. Adult male Sprague-Dawley rats were randomly divided into three MDMA dosage groups (2.5 mg/kg, 5.0 …

Dose-Response Characteristics Of Methylphenidate On Locomotor Behavior And On Sensory Evoked Potentials Recorded From The Vta, Nac, And Pfc In Freely Behaving Rats, Pamela B Yang, Alan C Swann, Nachum Dafny

Faculty, Staff and Student Publications

BACKGROUND: Methylphenidate (MPD) is a psychostimulant commonly prescribed for attention deficit/hyperactivity disorder. The mode of action of the brain circuitry responsible for initiating the animals' behavior in response to psychostimulants is not well understood. There is some evidence that psychostimulants activate the ventral tegmental area (VTA), nucleus accumbens (NAc), and prefrontal cortex (PFC).

METHODS: The present study was designed to investigate the acute dose-response of MPD (0.6, 2.5, and 10.0 mg/kg) on locomotor behavior and sensory evoked potentials recorded from the VTA, NAc, and PFC in freely behaving rats previously implanted with permanent electrodes. For locomotor behavior, adult male Wistar-Kyoto …

Vital Pulp Therapy With Mineral Trioxide Aggregate: An Outcomes Study, Heather H. Lauer

MTA is proven to provide good marginal adaption to dentin, to be biocompatible, and to stimulate dentin bridge formation through animal studies. These properties make MTA a potentially useful material to be used in vital pulp therapy. Clinical data on the use of MTA as a vital pulp medicament is sparse. The purpose of this study was to evaluate the clinical outcome of vital pulp therapy using MTA as the pulp medicament. Inclusion criteria for patient selection for recall was based on pulp treatment necessary from carious pulp …

Mechanisms Of Hbo-Induced Neuroprotection In A Neonatal Hypoxia-Ischemia Model, John Winter Calvert

Loma Linda University Electronic Theses, Dissertations & Projects

With an incidence approaching 1/4000 live births and as high as 60% in low birth weight infants, cerebral hypoxia-ischemia during the perinatal period is the single most important cause of acute mortality and chronic disability in newborns. Herein, we tested the hypothesis that following a hypoxic-ischemic insult hyperbaric oxygen (HBO) treatment can restore high energy metabolite levels in the affected regions of the brain and through this increase in energy levels ameliorate the spread of cell death following the insult. We also investigated if an additional mechanism by which HBO affords its neuroprotection is by altering the expression of the …
