Phytophthora species and oak decline - can a weak competitor cause significant root damage in a nonsterilized acidic forest soil?

Phytophthora species in general, and P. quercina in particular, have been suggested in several studies to be a contributing factor to the problem of oak decline in Europe. Although Phytophthora species are generally regarded as weak competitors, few studies of the pathogenicity of species causing root rot on oaks have hitherto been performed in natural, nonsterilized forest soils. This study descr

Predictive markers for tamoxifen response in primary breast cancer

It is well-known that a majority of breast cancers are hormone-dependent, making endocrine therapy an important adjuvant treatment after surgery. Susceptibility to endocrine treatment is determined by the presence of estrogen receptors (ER) and progesterone receptors (PR) in the tumors. Tamoxifen is the most well-established endocrine treatment available, inhibiting tumor growth and improving surv

Negative Pressure Wound Therapy - Mechanisms of Action and Protecting Exposed Blood Vessels in the Wound Bed

NPWT has recently been associated with severe complications and bleeding when used in wounds with exposed blood vessels. The aims of this work were to investigate the mechanisms of action of NPWT and to explore the possibility of using thin plastic discs to protect exposed blood vessels in the wound bed during NPWT. Three different kinds of wounds were created in pigs: 6 cm and 10 cm diameter circ

The Reflux Disease Questionnaire: a measure for assessment of treatment response in clinical trials

Background: Critical needs for treatment trials in gastroesophageal reflux disease (GERD) include assessing response to treatment, evaluating symptom severity, and translation of symptom questionnaires into multiple languages. We evaluated the previously validated Reflux Disease Questionnaire (RDQ) for internal consistency, reliability, responsiveness to change during treatment and the concordance

Ultrasound features of human carotid plaques

Atherosclerotic plaques in the carotid arteries are common in a middle-aged population. When a carotid plaque ruptures it may result in a cerebrovascular event. However, only a minor part of carotid plaques will eventually rupture. Finding those plaques is essential to decide the most appropriate treatment strategy. With non-invasive ultrasound the carotid plaques can be visualized for assessment

Combined chemotherapy and immunotherapy against experimental malignant brain tumors

Glioblastoma multiforme (GBM) is the most common and aggressive primary malignant brain tumor in adults. Despite standard treatment including surgery, radiotherapy and temozolomide (TMZ)-based chemotherapy, the prognosis for GBM patients is dismal, and there is a need for novel treatments. One possible therapeutic treatment modality presented here is immunotherapy, either alone or combined with in

Prosthetic and Orthotic Services in Developing Countries

Aim: The overall aim of this thesis was to generate further knowledge about prosthetic and orthotic services in developing countries. In particular, the thesis focused on patient mobility and satisfaction with prosthetic and orthotic devices, satisfaction with service delivery, and the views of staff regarding clinical practice and education. Methods: Questionnaires, including QUEST 2.0, were use

Towards Generation of Human Hematopoietic Stem Cells from Pluripotent Stem Cells.

There is a pressing need for compatible Hematopoietic Stem Cells (HSCs), in high quantities and of good clinical quality, to ensure optimal treatment for patients with various blood malignancies. Pluripotent Stem Cells (PSCs) have the potential to be a source for generating HSCs. The indefinite expansion capacity of PSCs, combined with the possibility of creating these cells from patient-specific

Molecular Genetic Characterization of Acute Lymphoblastic Leukemia with a Poor Prognosis

Acute lymphoblastic leukemia (ALL) affects individuals at all ages, with peak incidences in children <4 years and adults >50 years. ALL is broadly categorized into B-cell precursor (BCP) and T-cell ALL with specific clinical features associated with outcome. In contrast to pediatric ALL, which has a favorable prognosis, adult ALL is associated with a much poorer outcome with less than 40% overall
