Background/Aims: Two differently charged polypeptides, poly-L-lysine (PL) and poly-L-glutamate (PG), have previously been shown to reduce postoperative intra-abdominal adhesions. This study aims to investigate the possible toxic effects and to establish a lowest effective antiadhesive dose. Methods: 152 mice were investigated with a well-known adhesion model and given different concentrations of t

Structural compromise of the tumor suppressor gene, PTEN occurs in 10% of melanoma specimens and loss of PTEN expression through DNA methylation of the PTEN promoter region has also been reported in a number of other malignancies. However, the role of PTEN promoter methylation in melanoma is not well understood. We thus sought to elucidate the prevalence of PTEN promoter methylation in melanoma sp

Sclerosing injections under ultrasonographic guidance is a new method of treatment for persistent pain in Achilles tendinosis. Good results, even superior to those of surgery, have been described. We report the outcome of 25 patients with midportion tendinosis receiving sclerosing treatment. Twenty-eight consecutive patients (29 tendons) with ultrasonographical findings of midportion tendinosis ex

The c-kit-encoded tyrosine kinase receptor for stem cell factor (Kit/SCFR) is crucial for the development of hematopoietic cells, melanoblasts, and germ cells. Ligand stimulation of Kit/SCFR leads to receptor dimerization and autophosphorylation on tyrosine residues. We recently showed, that protein kinase C (PKC) acts in an SCF-stimulated negative feedback loop, which controls Kit/SCFR tyrosine k

Despite the spatially homogenous summer temperaturepattern in Fennoscandia, there are large spreadsamong the many existing reconstructions, resulting in anuncertainty in the timing and amplitude of past changes.Also, there has been a general bias towards northernmostFennoscandia. In an attempt to provide a more spatiallycoherent view of summer (June–August, JJA) temperaturevariability within the l

The idea to use transplants of dopamine-producing cells to substitute for the lost midbrain dopamine neurons in Parkinson's disease (PD) goes back to the 1970s. In this review we give an overview of the history of cell transplantation in animal models of PD, and summarize the experience gained from the open-label and placebo-controlled clinical trials performed so far using intrastriatal transplan

The contribution of hereditary factors for development of childhood tumors is limited to some few known syndromes associated with predominance of tumors in childhood. Occurrence of childhood tumors in hereditary cancer syndromes such as BRCA1/2 associated breast and ovarian cancer, DNA-mismatch repair (MMR) genes associated hereditary non polyposis colorectal cancer and CDKN2A associated familial

Sp1/Kruppel-like factor (KLF) family of transcription factors regulates diverse biological processes including cell growth, differentiation, and development through modulation of gene expression. This family of factors regulates transcription positively and negatively by binding to the GC and GT/CACCC boxes in the promoter through their highly conserved three zinc finger domains. Although the mole

AIMS/HYPOTHESIS: Type 2 diabetes is a chronic metabolic disorder associated with devastating microvascular complications. Genome-wide association studies have identified more than 60 genetic variants associated with type 2 diabetes and/or glucose and insulin traits, but their role in the progression of diabetes is not established. The aim of this study was to explore whether these variants were al

PURPOSE: Although survival has been studied for various subtypes of non-Hodgkin's lymphoma (NHL), there have been few comprehensive studies to quantify the prognosis, including all specific histologies. The effect of family history on survival in NHL has not been examined. METHODS: We used the Swedish Family-Cancer Database to estimate hazard ratios in NHL by histology and family history. RESULTS:

We present a new method for investigating the nonperturbative quantum mechanical interaction of light with atoms in two dimensions, without a basis expansion. This enables us to investigate intense laser-atom interactions with light of arbitrary polarization without approximation, within the model restrictions. Results are presented for the dependence of ionization and high harmonic generation on

Approximately 8% of clear cell renal cell carcinoma cases contain regions of radically different morphology, demonstrating a mesenchymal appearance histologically resembling sarcomas. These biphasic neoplasms are called sarcomatoid clear cell renal cell carcinoma. Patients diagnosed with sarcomatoid clear cell renal cell carcinoma face a considerably worse prognosis due to an increased propensity

The objective of this study is to investigate whether vestibular rehabilitation can improve balance, reduce self-perceived handicap because of dizziness and, if possible, reduce falls among dizzy patients in primary healthcare. The study also finds out which of the balance measures and measure of self-perceived handicap, if any, predicted the risk of falls. The design of this study is an intervent

Previous data have indicated that IL-21 and/or IL-21R are crucial for the differentiation of naïve T cells into Th17 cells and also play a key role in the development of autoimmune disease. Given this, IL-21 and/or IL-21R are potential targets for therapy of such diseases; however, a study in this issue of the European Journal of Immunology, provides a new twist in the story as it is now shown tha

Relations between Generalized LDPC codes, nonbinary LDPC codes, and woven graph codes are considered. Focus is on rather short codes suitable, for example, for coding control signaling information in mobile communications. In particular, codes of lengths less than 200 bits are studied. Low-complexity near maximum-likelihood (ML) decoding for these classes of codes is introduced and analyzed. Frame

We examined overall and specific cancer risks among Swedish subjects who had been hospitalised one or more times for psoriasis. A database was created by identifying such patients from the Swedish Hospital Discharge Register and linking them with the Cancer Registry. Follow-up of patients was carried out from the last hospitalisation through 2004. A total of 15 858 patients were hospitalised for p
