Midlatitude sporadic-E layers
… the partially transparent echo from midlatitude sporadic-E layers as recorded by ionosondes; this is the range of frequencies between the blanketing frequency and the maximum frequency. One interpretation is that it is a partial reflection at the steep gradients of electron density which …

Fluxes of Sporadic Meteoroids from Optical Measurements
… the speed distribution, and the flux of the sporadic meteor sources using an electro-optical system. Data was recorded on two nights, April 27 and May 6, 2006, and the system was tested by measuring the flux of the eta Aquariid meteor shower. Eta Aquariid fluxes yielded ZHRs of 14.3 ± 4.5 …

Mitochondrial Biology in Sporadic Inclusion Body Myositis
Sporadic Inclusion Body Myositis (sIBM) is an inflammatory muscle disease that strikes individuals at random and accounts for approximately 1/3 of all idiopathic inflammatory myopathies. It is characterized by progressive weakness of distal and proximal muscles and is the most common muscle …

Sporadic cerebral small vessel disease and cognitive abilities
Cerebral small vessel disease (SVD) is a leading cause of vascular cognitive impairment, contributing to multiple neurological disorders ranging from stroke, to mild cognitive impairment and dementia. However, despite a huge number of studies on the subject, we have a limited understanding of how …

Epigenetic silencing of BRCA1 and maspin in sporadic breast cancer
… and maspin are frequently decreased or lost in sporadic breast cancer. We hypothesized that inactivation of these genes was due to aberrant epigenetic silencing at the level of gene transcription. In this study we show that aberrant cytosine methylation of the BRCA1 and maspin CpG island …

Sporadic Burkitt Lymphoma in Adults; Clinico-pathologic Characteristics and Immunohistochemical Study
… stains and treatment outcome of patients with sporadic Burkitt lymphoma (BL) in adults. METHODS: A survey of 1,422 NHL patients who had been diagnosed at Korea Institute of Radiological & Medical Sciences between 1993 and 2003 identified 26 patients with BL (1.8%). All these cases were reviewed …

Modeling Sporadic Tumor Formation Driven By Telomere Dysfunction In The Gastrointestinal Tract
… mechanisms for generating such mutations in sporadic colon cancer; one of which is chromosomal instability (CIN). One hypothesized driver of CIN in cancer is the improper repair of dysfunctional telomeres. Telomeres comprise the linear ends of chromosomes and play a dual role in cancer. Its …

Bayesian Transfer Learning for personalised well-being forecasting from scarce, sporadic observations
… training is performed incrementally on scarce sporadic biomedical data. A particular challenge was being able to provide reliable personalised predictions in the early stage of data collection when insufficient data are available for training.The solution proposed in this dissertation is …

A clinical and molecular genetic study into familial and sporadic Parkinson’s Disease
… an extensive screen of LRRK2 in UK subjects with sporadic PD (sPD). This confirms the importance of pathogenic LRRK2 mutations in UK sPD. In addition I report a novel missense mutation in the GTP cyclohydrolase I gene (GCH1) in a kindred with phenotypes ranging from PD to Dopa-responsive dystonia. …

Phenotypic and genotypic analysis of persistent and sporadic isolates of listeria monocytogenes
… and characterized putative persistent and sporadic isolates from 30 retail delis in three regions of the U.S. over six months. Next generation sequencing allowed phylogenetic relationships to identify persistent strains based on the assumption that isolates of a persistent strain were more …

A 3-local characterization of the group of the Thompson sporadic simple group
In this thesis we characterize the Thompson sporadic simple group by its 3-local structure. We study a faithful completion, \(G\), of an amalgam of type F\(_3\) with the property that \(N_G(Z(L_\beta)) = G_\beta\). We first assume no additional 3-local structure and use a \(\kappa\)-proper …

Revealing Mechanisms of Sporadic Alzheimer’s Disease by Modelling in Organotypic Hippocampal Slice Cultures
… cases are inherited, a majority of patients have sporadic disease. Thus, it is a combination of one’s genes, environment and lifestyle which ultimately determine whether they develop dementia. Two of the defining hallmarks of AD include deposits of extracellular amyloid-β (Aβ) plaques and …

Investigation of Endogenous Retroviruses in the Pathogenesis of Sporadic Amyotrophic Lateral Sclerosis (ALS) by
Human Endogenous Retroviruses (HERVs) are remnants of ancient retroviral infections that have become incorporated into the human genome over the course of our evolution as a species. These fossil viruses have been co-opted by our genome as regulators of cellular gene expression amongst various …
