The present study determined mutations of phosphatase and tensin homolog (PTEN) gene in patients suffering from high-grade gliomas (WHO grades III and IV) and further investigated the mutations in correlation to patients' histopathological classification and short-term survival. Total RNA and genomic DNA were extracted from tumor tissues. Full-length PTEN cDNA sequences were amplified by polymeras
A study performed in a group of 59 premenopausal women. For the majority it could be shown that creativity, as measured by the Creative Functioning Test, correlated with a favorable prognosis. It was concluded that suppression of aggression could be a negative factor in the development of cancer growth. In a small group with comedo carcinoma these relations were reversed. Test results suggested th
Eighty basal cell carcinomas (BCCs) in 21 patients, 10 lesions of Bowen's disease in three patients, and four lesions of cutaneous T-cell lymphoma in two patients, were treated with photodynamic laser therapy (PDT), using topical application of the haem precursor delta-amino levulinic acid (ALA). The diagnoses were confirmed histologically prior to treatment. Fifty-five of the BCCs were superficia
Welding fumes include agglomerated particles built up of primary nanoparticles. Particles inhaled through the nose will to some extent be deposited in the protein-rich nasal mucosa, and a protein corona will be formed around the particles. The aim was to identify the protein corona formed between nasal lavage proteins and four types of particles with different parameters. Two of the particles were
Small supernumerary marker chromosomes (sSMCs) derived from the near-centromeric area of chromosome 2 are very rare. In addition, duplications of the 2p11.2-->q11.2 region have displayed considerable variability between patients harboring and lacking clinical findings. Moreover, constitutional duplication of the 19q12-->q13.2 region has previously only been described in two cases and was associate
The generation of high quality plasma from whole blood is of major interest for many biomedical analyses and clinical diagnostic methods. However, it has proven to be a major challenge to make use of microfluidic separation devices to process fluids with high cell content, such as whole blood. Here, we report on an acoustophoresis based separation chip that prepares diagnostic plasma from whole bl
Angiogenesis inhibition is an established treatment for several tumor types. Unfortunately, this therapy is associated with adverse effects, including hypertension and renal toxicity, referred to as "preeclampsia." Recently, we demonstrated in patients and in rats that the multitarget tyrosine kinase inhibitor sunitinib induces a rise in blood pressure (BP), renal dysfunction, and proteinuria asso
The clinical outcome for patients with chronic myeloid leukemia (CML) has improved dramatically following the introduction of tyrosine kinase inhibitors. An improved survival, combined with a constant incidence, is expected to increase the prevalence of CML. However, data on the prevalence of CML remain scarce. We examined the overall and relative (age and gender matched) survival and assessed the
Hospitalization and surgery are stressful experiences for children and their parents. In recent years, pediatric health care has shifted toward family-centered care that is based on close and continuous involvement of the child's family members. To shape and improve how pediatric care is delivered, health care providers need to know what children and parents need, expect, and experience. Such know
INTRODUCTION: Correlation function analysis applied to endocardial electrograms has earlier been used for analysis of agreement between signals and direction of activation during atrial fibrillation (AF). This study was aimed at evaluating whether preferential activation patterns along the coronary sinus (CS) exist in patients with AF. METHODS: Twenty-seven patients (57 ± 10 years old) admitted fo
Titanium dioxide (TiO2) has very high affinity for phosphopeptides and in recent years it has become one of the most popular methods for phosphopeptide enrichment from complex biological samples. Peptide loading onto TiO2 resin in a highly acidic environment in the presence of 2,5-dihydroxybenzoic acid (DHB), phthalic acid, lactic acid, or glycolic acid has been shown to improve selectivity signif
Purpose. To evaluate the retinal function, with emphasis on phenotype and rate of progression, in infants and children with different genotypes of Usher syndrome. Methods. Fourteen children (2-10 years of age) with retinitis pigmentosa and hearing impairment were examined with full-field electroretinography (ERG) during general anesthesia, ophthalmologic examination, and genetic analysis. Five chi
OBJECTIVES: To investigate the incidence and outcomes of acute lower gastrointestinal bleeding (ALGIB) in a population-based setting and examine the role of drugs potentially associated with GIB. METHODS: The study was prospective and population based. The cohort included all patients who underwent colonoscopy during the year 2010 at the National University Hospital of Iceland. Indications for
PURPOSE: Anticipation (ie, an earlier age at onset in successive generations) is linked to repeat expansion in neurodegenerative syndromes, whereas its role in hereditary cancer is unclear. We assessed anticipation in Lynch syndrome (hereditary nonpolyposis colorectal cancer [HNPCC]), in which DNA mismatch repair (MMR) defects cause early and accelerated tumor development with a broad tumor spectr
In this study we have elucidated the effects of allergen-specific antibodies on human DCs and T-cells. Monocyte-derived DCs from allergic patients were exposed to Phlp 5 alone or in complex with Phlp 5-specific human IgG1, IgG4 or IgE and further co-cultured with autologous memory CD4+ T-cells. We demonstrate that DCs treated with Phlp 5/IgE-complexes secrete higher levels of IL-1a, IL-6, VEGF and
We report a population based case-control study of exposure to pesticides as risk factor for non-Hodgkin lymphoma (NHL). Male and female subjects aged 18-74 years living in Sweden were included during December 1, 1999, to April 30, 2002. Controls were selected from the national population registry. Exposure to different agents was assessed by questionnaire. In total 910 (91 %) cases and 1016 (92%)
