Non-invasive diagnostic methods of intracranial arteries
… arteries, and finally to evaluate the diagnostic accuracy of CTA in non-traumatic subarachnoid haemorrhage (SAH) compared to DSA and to assess the arterial attenuation (HU) as an image quality factor in this aspect. Follow-up DSA and time-of-flight (TOF) MRA at 1.5T and 3T as well as …

Peripheral blood mononuclear cells as non-invasive diagnostic indicators of stress-associated neural states
… in support of such an approach as a viable diagnostic avenue within psychiatric settings is accumulating, it remains to be demonstrated, in an animal model, that transcriptional changes in peripheral tissue targets are paralleled by specific gene expression changes in neural tissues.

Ultrasound as a non-invasive diagnostic tool in paediatric neurosurgery : relationship between the optic nerve sheath diameter (ONSD) and intracranial pressure (ICP)
… most neurosurgical conditions in children. While invasive ICP monitoring is considered the criterion standard, the need for a reliable, non-invasive, easy-to-use and accurate method to detect and monitor raised ICP has inspired the development of many useful techniques. The present study examined …

The identification of structural modal parameters, as an alternative in-vivo diagnosis for osteoporosis
An alternative non-invasive diagnostic technique was sought for the diagnosis of osteoporosis in human subjects. The tibia vibration technique was proposed after reviewing the literature on detection techniques for osteoporosis. The basis of diagnosis of the tibia vibration technique is the …

Microbial communities as predictors of outcomes in industrial and clinical applications
… for three applications: bioreactor function; a non-invasive diagnostic of endometriosis; and commercial chicken rearing. I identify bacteria that exhibit distinct temporal dynamics within each application, and discuss the implications of those dynamics in the context of each application. Despite …

Development of Strategies for Improving the Isolation Efficiency and Protein Quantification of Extracellular Vesicles
… their protein content can potentially be used as diagnostic and prognostic tools. In this thesis, efficient and simple strategies to improve the EV isolation efficiency with an affinity-based method were developed. Furthermore, optimization of immunoassays towards multiplexed EV protein …

Stellenwert der optischen Kohärenztomographie in der Beurteilung epithelialer Hauttumoren : eine offene klinische Studie zur nicht-invasiven In-vivo-Anwendung der optischen Kohärenztomographie
The epithelial skin tumors and preinvasive lesions became an increasingly important due to rising incidence in the last few years. The determination between preinvasive and initially invasive lesions and presentation of tumor margins are conditions for apply of non-invasive therapies. Since 1995 …

Development of Electrochemical Immunosensor for Oral Cancer: Initial Outcome
… (OL) underscores the urgent need for an early, non-invasive diagnostic tool. This thesis investigates the use of a nanoengineered electrochemical immunosensor targeting the S100A7 protein, a biomarker associated with OSCC risk. The biosensor's sensitivity and specificity were assessed across a …

Nové diagnostické metody v dermatologii: neinvazivní diagnostika nemelanomových nádorů kůže
Non-melanoma skin cancer (NMSC) is the most prevalent cancer in the light-skinned population. New less- or non-invasive treatments are increasingly used for NMSC patients, making the development of non-invasive diagnostic technologies highly relevant. The scope of this work is to present data on …

Comparison of two different methods to detect telomerase activity in normal and neoplastic lymph nodes in the dog
… cancer cells are thought to undergo a phenomenon of immortalization. The chromosome extremities contain structurally defined elements called telomeres. In normal somatic cells, each mitotic cycle leads to a reduction of telomere lenght until a critical point is reached. Telomere erosion to …

A data mining approach for acoustic diagnosis of cardiopulmonary disease
… lung auscultation offers a low-cost, non-invasive diagnostic procedure that gives doctors better clinical utility especially in situations when x-rays and CT scans are not available.

Developing a low-cost cardiovascular mobile screening kit
… most people are asymptomatic. Thus, low-cost non-invasive diagnostic tools are crucial in low-resource areas without routine blood tests or regular clinical exams. This thesis presents a low-cost cardiovascular screening kit that focuses on signs of arterial stiffening, the root issue of many …

Collagen-mimetic peptides for diagnosis and analysis
… This thesis explores the application of CMPs in diagnostic applications, in which CMPs detect aberrations in native collagen, and analytical contexts, in which CMPs act as a simplified system to understand collagen biochemistry. Chapter 2 investigates the ability of CMPs to identify collagen …
