Dynamic Markers
When I was a child, I was certain that all clouds came from New Jersey. After passing through the Lincoln Tunnel, I-95 would gradually ascend, lifting our car to eye level with the billowing clouds emerging from beneath us. These clouds rose from the Meadowlands, a great marsh just two miles west …

Behavioral and linguistic markers of craving
Craving, a strong desire or urge to use a substance, is a primary trigger for relapse in individuals living with substance use disorder (SUDs). Environmental cues repeatedly paired with substance use can acquire motivational salience, and later exposure to these cues outside of the substance-use …

Apoptotic markers in ejaculated human spermatozoa
… was to evaluate the presence of four apoptotic markers on sperm from patients with various grades of fertility using flow cytometry. Furthermore, any correlations between the apoptotic marker assays and the standard semen analysis results were identified. This study compares early and late …

Neuronal and Electrophysiological Markers of Glioma
The research performed in this thesis aims to improve our understanding about one of the most malignant tumors of the human brain – glioma. From the early stages of my career I was confronted with the cruel reality of losing patients due to this devastating disease. The studies performed over the …

Markers of Prognosis in Neurodegenerative Dementia
… in patients or subgroups of patients. Prognostic markers could be targeted to apply during the entire clinical course or just during distinct stages of the disease. Aim: The aim of this thesis is to identify, review and qualify possible indicators, including biological markers to predict course …

Immunological markers in hairy-cell leukaemia
… 1 presents a brief introduction on immunological markers. Chapter 2 describes the discovery of a previously unrecognised marker in hairy-cell leukaemia (HCL), a receptor for IgM. The rosette method used to reveal this receptor, and the conditions affecting rosette formation are described. A …

Biochemical markers and contact lens wear
… by the nature of the lipid deposition. Potential markers within the lipid species have been identified and could be applied as follows: When required in order to identify a problematic wearer or to match the contact lens material to the contact lens wearer, tear samples collected by the clinician …

Molecular Markers Applied to Maize Breeding
Three experiments were conducted to develop methods to practically apply restriction fragment length polymorphisms (RFLPs) to maize (Zea mays L.) breeding. Applications included those requiring linkage between marker loci and loci governing traits of interest and those not requiring linkage.

Judging essays : factors that influence markers
This thesis is an exploration of assessment with particular focus on the marking of essay assignments and the validity or soundness of that process.

Assessment of redox markers in cattle
… health and production. Antioxidants and biomarkers of oxidative stress were evaluated in cattle under three phases of management. Each phase stood alone as a treatment model, and managerial aspects during the phase were evaluated as potential moderators of redox balance. Yearling heifers …

Ancestry Informative Markers Tailored to Hispanic Populations
… makes an accurate panel of ancestry informative markers (AIMs) especially important for human identification. In Chapter 2, the Genomic Origins and Admixture in Latinos (GOAL) dataset containing 494,886 SNPs was used for SNP ascertainment. Utilizing a country attributable variant of Wright's FST, …

Mapping and Localization Using LiDAR Fiducial Markers
… for autonomous systems, yet LiDAR fiducial markers (LFMs) lag behind visual fiducial markers (VFMs) in adoption and utility. Bridging this gap is vital for robotics and computer vision but challenging due to the sparse, unstructured nature of 3D LiDAR data and 2D-focused fiducial marker …

Pathologic Markers of Prognosis In Ampullary Carcinoma
<p>Ampullary cancer is a rare gastrointestinal malignancy that can be curable with surgical resection of localized disease. The benefit of adjuvant therapy, however, remains unknown in these patients partly because of difficulty in stratifying which patients are at high risk for recurrence. To …

Clincal Aspects of Biological Brain Damage Markers
Biomarkers for organ damage and/or dysfuntion are used in almost all areas of medicine. The brain has eluded this technological development for some time. Recently, the S100B protein has been shown to be a promising marker of brain damage. However, before S100S can reach clinical reality, several …

Study of prognostic markers in advanced cancer
… in patients with cancer. These can be clinical markers or biomarkers. Clinical markers including weight loss and Performance Status (PS), and biomarkers such as C-reactive protein (CRP), lactate dehydrogenase (LDH), White cell count (WCC) and albumin, all representative of systemic inflammation, …

Imputation of Microsatellite Markers With Tag SNPs
<p>Of the two most common forms of genetic variation in the human genome, Single Nucleotide Polymorphisms (SNPs) and Variable Number Tandem Repeat Polymorphisms (VNTRs), SNPs are much more easily and inexpensively assayed in a high-throughput manner. For this reason, we seek to explore methods that …

Identification of biological markers for neuropsychiatric disorders
… The positive correlation of these biochemical markers with the diagnosis of dementia and depression suggests the presence of a similar pathological 'pattern' underlying both disorders which is in agreement with the hypothesis of a common substrate of vascular pathology in both dementia and …
