Non-invasive diagnosis of non-alcoholic fatty liver disease.
Non-alcoholic fatty liver disease (NAFLD) has become one of the top concerns for the practising hepato-gastroenterologist due to the obesity epidemic and its potential to progress to an advanced liver disease that significantly impacts on overall and liver-related mortality. Due to the rapidly …

Improving earlier non-invasive diagnosis of high-grade serous ovarian cancer
… ovarian cancer (OC) have advanced disease at diagnosis and 5-year survival rates of less than 25%. Women with stage I disease have significantly better 5-year survival rates of over 90%. Recent large studies using CA 125 and transvaginal ultrasound have failed to improve mortality in a …

Plasmonic Detection of microRNA Biomarkers in Microfluidic Devices for Brain Cancer Non-Invasive Diagnosis
… una tecnica diagnostica affidabile, economica e non invasiva con effetti collaterali minimi, è una delle principali sfide mediche e sociali dell'UE. La biopsia liquida ha guadagnato molta attenzione per il rilevamento e caratterizzazione di biomarcatori circolanti, come microRNA circolanti, i …

Carbon Nanotube-Based Wearable Sweat Sensors; Design and Fabrication
Wearable sweat sensors enable non-invasive diagnosis of various diseases and real-time health monitoring. Few sensors exhibit pH measurement on skin due to interference by sodium chloride ions. This thesis presents a multiplexing wearable sweat sensor using single and multi-walled carbon nanotubes. …

Urinary Volatile Organic Compounds (VOCs) in the Diagnosis of Urothelial Bladder Cancer
… bladder cancer. However, it is expensive and invasive, and has difficulties in diagnosing early stage cancer or carcinoma in situ (flat tumour). Non-invasive diagnosis of bladder cancer like urine cytology and urinary biomarker tests have poor specificity therefore they are used as supportive …

Next Generation Sequencing nell'analisi del DNA fetale da plasma materno per la diagnosi prenatale non invasiva di malattie genetiche
… reasons that prompt couples to opt for prenatal diagnosis (PD). Unfortunately, current procedures of prenatal diagnosis are invasive and carry a 0.5-1% risk of fetal mortality. The discovery of fetal DNA in maternal plasma had opened new opportunities for non invasive diagnosis and to date, …

MRI brain tumour classification using image processing and data mining
… effective treatment. The general brain tumour diagnosis procedure, biopsy, not only causes a great deal of pain to the patient but also raises operational difficulty to the clinician. In this thesis, a non-invasive brain tumour diagnosis system based on MR images is proposed. The first part is …

Multimodal intravital imaging of tissue structure and cell dynamics in skin using integrated optical coherence and multiphoton microscopy
… for clinical applications to potentially enable non-invasive diagnosis of skin diseases. The methods presented are based on a multimodal microscope that integrates optical coherence and multiphoton microscopy. The development of the integrated microscope was focused on enabling sufficient …

Plasmatische und zelluläre, nicht invasive Biomarker für die Diagnostik kardialer Abstoßungsreaktionen
The search for effective non-invasive biomarkers for rejection after organ transplantation has occupied research for many years. Invasive biopsies are still the only way to detect rejection after heart transplantation beyond doubt. Therefore, the focus of the present work was on potential plasmatic …

smart-Kage: Autonomous behavioural phenotyping in a rodent home-cage environment
… We demonstrated the ability of our system for non-invasive diagnosis of underlying brain damage by successfully discriminating between mice with hippocampal, medial-entorhinal and sham lesions along with predicting the genotype of mice serving as models of Alzheimer’s disease with high …

LncRNA and circRNA expression profiles in tissues and serum exosomes of colorectal cancer patients and cell lines
… studies demonstrated the fundamental role of non-coding RNAs (ncRNAs) in tumor onset and progression. While the involvement and the mechanism of action of microRNAs (miRNAs) have been widely investigated, little is known about long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs), which …
