BACKGROUND: The progression of tumor growth requires the recruitment of new blood vessels. It has been suggested that the degree of neovascularization would correlate with clinical prognosis. The purpose of the present study was to ascertain whether tumor vascularization correlated with clinical outcome in cases of primary squamous cell carcinoma of the head and neck (SCCHN).METHODS: In tumor biop
Prognostic factors and treatment results were analysed in 72 consecutive patients with primary gastric lymphoma treated between 1970 and 1985. There were 37 patients in stage IE, 17 in IIE, 3 in IIES and 15 in stage IV. Histopathological re-evaluation and classification according to the TNM system were performed. We found that disseminated disease (stage IV), serosal penetration (T3), involvement
A significantly increased frequency of chromosomal aberrations was found in lymphocytes from eight psoriatic patients previously treated with arsenic than in lymphocytes from eight psoriatics with no such previous treatment. In most patients the arsenic therapy was discontinued more than 15 years ago. In the arsenic-treated group a statistically significant heterogeneity was found with respect to
Drug-resistant neuroblastoma remains a major challenge in paediatric oncology and novel and less toxic therapeutic approaches are urgently needed to improve survival and reduce the side effects of traditional therapeutic interventions. Mesenchymal stem cells (MSCs) are an attractive candidate for cell and gene therapy since they are recruited by and able to infiltrate tumours. This feature has bee
PURPOSE: Early metabolic response with a decrease in glucose demand after cytotoxic treatment has been reported to precede tumor volume shrinkage. However, preclinical studies report of a very early rise in metabolism, a flare, following treatment. To elucidate these observations, we performed an experimental study on early metabolic response with sequential analysis of metabolic changes. METHODS:
The present invention relates to a method of extg. 3-hydroxypropionaldehyde (3-HPA) and/or derivs. thereof from an aq. soln. comprising 3-HPA. This method comprises (a) contacting the aq. soln. comprising 3-HPA with chitosan and/or chitosan comprising polymers, (b) sepg. the 3-HPA bound chitosan and/or chitosan comprising polymers, and (c) washing the 3-HPA bound chitosan and/or chitosa
Ever since its introduction 40 years ago l-3,4-dihydroxyphenylalanine (l-DOPA) therapy has retained its role as the leading standard medication for patients with Parkinson's disease. With time, however, the shortcomings of oral l-DOPA treatment have become apparent, particularly the motor fluctuations and troublesome dyskinetic side effects. These side effects, which are caused by the excessive sw
We are constantly exposed to infectious diseases, and they cause millions of deaths per year. TheWorld Health Organization (WHO) estimates that antibiotic resistance could cause 10 million deaths per year by 2050. Multidrug-resistant bacteria are the cause of infection in at least one in three people suffering from septicemia. While antibiotics are powerful agents against infectious diseases, the
