Vitamin D Mitigates Age-Related Cognitive Decline Through The Modulation Of Pro-Inflammatory State And Decrease In Amyloid Burden, Teresita L. Briones, Hala Darwish

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Increasing evidence shows an association between the use of vitamin D and improvement in age-related cognitive decline. In this study, we investigated the possible mechanisms involved in the neuroprotective effects of vitamin D on age-related brain changes and cognitive function.

Methods

Male F344 rats aged 20 months (old) and 6 months (young) were used and randomly assigned to either vitamin D supplementation or no supplementation (control). A total of n = 39 rats were used in the study. Rats were individually housed and the supplementation group received a subcutaneous injection of vitamin D (1, α25-dihydroxyvitamin D3) 42 I.U./Kg …

Segmentation Of Corpus Callosum Using Diffusion Tensor Imaging: Validation In Patients With Glioblastoma, Mohammad-Reza Nazem-Zadeh, Sona Saksena, Abbas Babajani-Fermi, Quan Jiang, Hamid Soltanian-Zadeh, Mark Rosenblum, Tom Mikkelsen, Rajan Jain

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

This paper presents a three-dimensional (3D) method for segmenting corpus callosum in normal subjects and brain cancer patients with glioblastoma.

Methods

Nineteen patients with histologically confirmed treatment naïve glioblastoma and eleven normal control subjects underwent DTI on a 3T scanner. Based on the information inherent in diffusion tensors, a similarity measure was proposed and used in the proposed algorithm. In this algorithm, diffusion pattern of corpus callosum was used as prior information. Subsequently, corpus callosum was automatically divided into Witelson subdivisions. We simulated the potential rotation of corpus callosum under tumor pressure and studied the reproducibility of the …

Augmented Annotation And Orthologue Analysis For Oryctolagus Cuniculus: Better Bunny, Douglas B. Craig, Sujatha Kannan, Alan A. Dombkowski

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The rabbit is an important model organism used in a wide range of biomedical research. However, the rabbit genome is still sparsely annotated, thus prohibiting extensive functional analysis of gene sets derived from whole-genome experiments. We developed a web-based application that provides augmented annotation and orthologue analysis for rabbit genes. Importantly, the application allows comprehensive functional analysis through the use of orthologous relationships.

Results

Using data extracted from several public bioinformatics repositories we created Better Bunny, a database and query tool that extensively augments the available functional annotation for rabbit genes. Using the complete set of target genes …

Vip And Host Immunity, Xiaoyu Jiang

Wayne State University Dissertations

The purpose of the current dissertation was to examine how VIP regulates host immunity and corneal healing, specifically, its control of growth factors and TLR expression in the P. aeruginosa infected cornea. Firstly, VIP treatment increased growth factor expression (EGF, GHF, FGF and VEGF) in infected cornea. Notably, treatment with a mixture of EGF, FGF and HGF prevented corneal perforation, reduced pro-inflammatory cytokines and bacterial plate count, while increasing anti-inflammatory cytokines and antimicrobials such as murine beta-defensin2 and 3.

We also investigated the expression of TLR-signaling pathways in P. aeruginosa infected corneas with or without VIP treatment. PCR array and …

Endoplasmic Reticulum Calcium-Independent Phospholipase A2 Gamma (Er-Ipla2Γ): Role In Oxidative Stress-Induced Lipid Peroxidation, Ca2+ Release, Phospholipid Homeostasis And Cell Death In The Kidney, Andre Chioke Eaddy

MUSC Theses and Dissertations

Acute kidney injury and chronic kidney disease are becoming more prevalent and have high morbidity and mortality, and despite several therapies targeted towards treating or preventing kidney injury, outcomes have been unchanged for many years. Calcium­independent phospholipase A2y (iPLA2γ) is one of seven Ca2+-independent PLA2 enzymes and represents a potential therapeutic target in kidney disease because of its unique subcellular localization and its potential as the putative membrane remodeling/repair enzyme. Studies in our laboratory suggest iPLA2γ is cytoprotective during oxidant injury by preventing and/or repairing oxidant-induced lipid peroxidation and pointed to ER-iPLA2γ as the major component of membrane repair and …

Premalignant Oral Lesion Immunobiology: Immune Modulation And Vaccination, Anna-Maria Alicia De Costa

MUSC Theses and Dissertations

While studies have indicated that squamous cell carcinoma of the head and neck (HNSCC) is associated with immune suppression, these studies did not analyze the immune response at the dysplastic stage. This study utilized a mouse model of 4-nitroquinoline 1-oxide (4NQO)-induced oral carcinogenesis to examine the alterations in immune phenotype at the premalignant and malignant stages of HNSCC. Cervical lymph nodes of HNSCC-bearing mice were found to contain a greater number of cells, including a greater number of conventional (Tconv) and regulatory (Treg) T cells, compared to lymph nodes of control and premalignant lesion-bearing mice. Premalignant lesion-bearing mouse lymph nodes …

A Mathematical Model For Cell Cycle-Specific Cancer Virotherapy, Joanna R. Wares, Joseph J. Crivelli, Juraj Földes, Peter S. Kim

Department of Math & Statistics Faculty Publications

Oncolytic viruses preferentially infect and replicate in cancerous cells, leading to elimination of tumour populations, while sparing most healthy cells. Here, we study the cell cycle-specific activity of viruses such as vesicular stomatitis virus (VSV). In spite of its capacity as a robust cytolytic agent,VSVcannot effectively attack certain tumour cell types during the quiescent, or resting, phase of the cell cycle. In an effort to understand the interplay between the time course of the cell cycle and the specificity of VSV, we develop a mathematical model for cycle-specific virus therapeutics. We incorporate the minimum biologically required time spent in the …

Multimodal Imaging Evidence For Axonal And Myelin Deterioration In Amnestic Mild Cognitive Impairment, Brian T. Gold, Yang Jiang, David K. Powell, Charles D. Smith

Neuroscience Faculty Publications

White matter (WM) microstructural declines have been demonstrated in Alzheimer's disease and amnestic mild cognitive impairment (aMCI). However, the pattern of WM microstructural changes in aMCI after controlling for WM atrophy is unknown. Here, we address this issue through joint consideration of aMCI alterations in fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity, as well as macrostructural volume in WM and gray matter compartments. Participants were 18 individuals with aMCI and 24 healthy seniors. Voxelwise analyses of diffusion tensor imaging data was carried out using tract-based spatial statistics (TBSS) and voxelwise analyses of high-resolution structural data was conducted using …

Elderly Onset Of Weakness In Facioscapulohumeral Muscular Dystrophy, Dominic B. Fee

Neurology Faculty Publications

A 77-year-old male is presented. He had onset of proximal weakness 10 years earlier. His course was slowly progressive. Despite having phenotypic features of facioscapulohumeral muscular dystrophy (FSH), genetic testing for this was delayed because of his age of onset, lack of family history, and benign appearing muscle biopsy. This case is one of the oldest onset of weakness in genetically confirmed FSH and highlights the recognized expansion in phenotype that has occurred since the advent of genetic testing.
