Abstract:

The naturalisation and subsequent spread of non-indigenous plant species (NIPS) is a major problem for most regions of the world. Managing plant invasions requires greater understanding of factors that determine initial naturalisation and distribution of wild NIPS. By the year 2000, 2252 NIPS were recorded as wild (1773 fully naturalised and 479 casual) in New Zealand. From published literature and electronic herbaria records, I recorded year of discovery of wild populations, and regional distribution of these wild NIPS. I also recorded species related attributes hypothesised to affect natural

Abstract:

In this study, we have demonstrated that the preproghrelin derived hormones, ghrelin and obestatin, may play a role in ovarian cancer. Ghrelin and obestatin stimulated an increase in cell migration in ovarian cancer cell lines and may play a role in cancer progression. Ovarian cancer is the leading cause of death among gynaecological cancers and is the sixth most common cause of cancer-related deaths in women in developed countries. As ovarian cancer is difficult to diagnose at a low tumour grade, two thirds of ovarian cancers are not diagnosed until the late stages of cancer development resul

Biological invasions are rapidly gaining importance due to the ever-increasing number of introduced species. Alongside the plenitude of empirical data on invasive species there exists an equally broad range of mathematical models that might be of use in understanding biological invasions.

Abstract Bladder cancer when superficial has a good prognosis but it has a high recurrence risk and about 10–15% of the superficial carcinomas will progress into muscle invasive or metastatic type. The most powerful factor for predicting the behavior of bladder carcinoma is the stage of the tumor. Invasion to the lamina propria increases the risk of recurrence and progress to muscle-invasive tumor. Also grade of the tumor and tumor multiplicity associates with high risk for recurrence. New markers are still needed to find those patients who need more and better treatments to avoid the recurren

Spinal cord injury (SCI) leads to axonal damage and limits the ability of the brain to communicate with the rest of the body. Several bioengineered approaches have been developed for the recovery of SCI. Among these techniques, degradable guidance tubes have shown promising results. However, design of nerve guide tubes requires several design considerations and has been a significant challenge. To assess the efficacy of a prototypical implanted nerve guide tubes, it is essential to perform continuous monitoring.

Abstract Traditional clinicopathological factors are not accurate enough to predict the behavior of head and neck squamous cell carcinoma (HNSCC).

New prognostic markers have, however, been searched for in order to better identify patient groups in need of different treatments or follow-up. Gelatinases (MMP-2, -9) are endopeptidases associated with tumor invasion and angiogenesis, and their tissue inhibitors (TIMP-1, -2) are also linked to cancer cell invasion and metastasis formation.

Background: Consistent with the ‘reactivity hypothesis’, monitoring autonomic responses to exercise might be of value in clinical and high-performance settings. Post-exercise autonomic recovery may be non-invasively assessed using heart rate variability indices of cardiac parasympathetic neural activity (cPNA-HRV) and systolic time intervals reflecting cardiac sympathetic neural activity (cSNA-STI). However, the dose of exercise may confound autonomic recovery, independent of underlying pathology or function. This thesis investigated how these indices respond to variations of the factors const

Abstract:

Les activités anthropiques causent des invasions biologiques qui sont devenues un problème mondial susceptible de causer des dommages écologiques (p. ex., sur la biodiversité et l’habitat), économiques (sur les industries) et sociaux (sur le bien-être humain). La prévention et la détection précoce des nouvelles invasions sont des éléments essentiels pour la gestion des risques et des impacts sur les écosystèmes et les économies. Bien sûr, la prévention est préférable, mais la détection précoce est une étape cruciale pour enrayer la propagation ultérieure des espèces envahissantes, car elle off

Les progrès en anesthésie et en réanimation ont pour objectifs la réduction de la durée de surveillance et l’amélioration de la qualité de la récupération. Pour le cas particulier de l’assistance respiratoire, la capacité de surveiller et d’optimiser l’adaptation entre le patient et sa machine d’assistance est déterminante pour la qualité et la conduite des soins. Ce travail de thèse concerne dans sa première partie la mise en place et la validation d’un outil instrumental permettant de caractériser un comportement respiratoire par l’étude cycle à cycle du délai d’activation inspiratoire entre

Abstract:

During last decade, molecular biology evolution has lead to a deep knowledge of human genome allowing the in-utero diagnosis of a large number of genetic diseases. Now adays performing a prenatal diagnosis of chromosomal abnormalities and of genetic diseases, requires genetic material from the fetus and this is possible only by invasive procedures such as amniocentesis and chorionic villus sampling. The risk of miscarriage of these technics is between 0.5% and 1% and considering these limits, new alternative and non-invasive screening methods, based on ultrasound and/or biochemical parameters

Background Waiting times of the fast-track of bladder cancer in Sweden are prolonged compared with set lead times.Aim To investigate if stage and grade of tumor affects waiting times.Method Retrospective single center observational study, Örebro University Hospital, Sweden. All patients who underwent resection of tumor or cystoscopy with biopsy via the fast-track between July 1st 2017 and December 31st 2018 were included, n=119.Result The waiting times of muscle invasive tumors were in general longer than for non-invasive tumors.

Abstract:

This research investigated the use of DNA fingerprinting to characterise the bacteria Streptococcus pneumoniae or pneumococcus, and hence gain insight into the development of new vaccines or antibiotics. Different bacterial DNA fingerprinting methods were studied, and a novel method was developed and validated, which characterises different cell coatings that pneumococci produce. This method was used to study the epidemiology of pneumococci in Queensland before and after the introduction of the current pneumococcal vaccine. This study demonstrated that pneumococcal disease is highly prevalent

Abstract:

Background Novel theranostic options for high-risk non-muscle invasive bladder cancer are urgently needed. This requires a thorough evaluation of experimental approaches in animal models best possibly reflecting human disease before entering clinical studies. Although several bladder cancer xenograft models were used in the literature, the establishment of an orthotopic bladder cancer model in mice remains challenging. Methods Luciferase-transduced UM-UC-3LUCK1 bladder cancer cells were instilled transurethrally via 24G permanent venous catheters into athymic NMRI and BALB/c nude mice as well
