Reactive capsule formation around soft-tissue implants is related to cell necrosis

Low-density polethylene disks with smooth or course surfaces were implanted in the abdominal wall of rats, and the tissue response was evaluated after 1, 6, or 12 weeks. Cell damage was detected by two different methods. Cells with increased membrane permeability could be identified using fluorescence microscopy by injection of propidium iodide prior to the killing of the rats. Second, cell death

Core value-based corporate brand building

Abstract The aim of this article is to introduce a conceptual framework for a corporate brand building process based on core values. The nature, role, and function of core values are considered a central part of the value foundation of a corporate brand. In line with this reasoning, a distinction is also made between three groups of values: organisational values, core values, and added values. Th

Dissociation of the Inflammatory Reaction following PCI for Acute Myocardial Infarction

OBJECTIVES: Neutrophils are activated and infiltrate the myocardium after ischemia and reperfusion. The involvement of neutrophils in irreversible reperfusion injury is suggested by numerous experimental studies. The aim of this study was to investigate markers of neutrophil activation following reperfusion of acute myocardial infarction (AMI) accomplished with percutaneous coronary intervention (

Stem cell-based therapy for Parkinson's disease.

Motor dysfunctions in Parkinson's disease are considered to be primarily due to the degeneration of dopaminergic neurons in the substantia nigra pars compacta. Pharmacological therapies based on the principle of dopamine replacement are extremely valuable, but suffer from two main drawbacks: troubling side effects (e.g. dyskinesia) and loss of efficacy with disease progression. Transplantation of

Dyskinesias and dopamine cell replacement in Parkinson's disease: a clinical perspective.

Both increased and decreased dyskinesias have been reported from open label clinical trials of transplantation of human embryonic dopamine rich tissue in Parkinson's disease patients. In the first double-blind clinical transplantation trial, 15% of the grafted patients developed severe postoperative dyskinesias in the “off” phase. Since then, postoperative off-medication dyskinesias have been repo

Impact of harvest year on amino acids and sugars in potatoes and effect on acrylamide formation during frying

Acrylamide is formed via the Maillard reaction between reducing sugars and asparagine in a number of carbohydrate-rich foods during heat treatment. High acrylamide levels have been found in potato products processed at high temperatures. To examine the impact of harvest year, information on weather conditions during growth, that is, temperature, precipitation, and light, was collected, together wi

Association between thyroid hormone levels and monoaminergic neurotransmission during surgery

Background: Human studies assessing thyroid hormone metabolism in relation to brain monoaminergic activity in vivo are scarce. The few studies that do exist suggest significant associations between thyroid function and monoaminergic activity, but the cause-and-effect relationships are far from elucidated. Methods: We simultaneously collected cerebrospinal fluid (CSF) and serum samples from 35 pati

Quantitative PSA RT-PCR for preoperative staging of prostate cancer

BACKGROUND. The clinical value of detecting prostate specific antigen (PSA) mRNA in the peripheral blood mononuclear cell fraction of patients (pts) by standard RT-PCR assays with localized prostate cancer remains controversial. We used a quantitative RT-PCR assay to measure the PSA mRNA copy number in addition to the qualitative PSA RT-PCR and correlated the results with clinical parameters. METH

Purpose: Transitional cell carcinoma (TCC) of the prostate/prostatic urethra is a risk factor for urethral recurrence after radical cystoprostatectomy for TCC. Using conventional sectioning techniques, prostate involvement (prostatic urethra, acini, ducts and/ or stroma) has been detected in a range of 10-20% of the patients, whereas transversal whole mount sectioning has revealed 43% prostate inv

Leukocyte Count and Incidence of Hospitalizations Due to Heart Failure

Background-Leukocyte concentration in blood is a classical marker of systemic inflammation. Whether high leukocyte counts are associated with incidence of heart failure (HF) is unknown. This population-based study explored whether the leukocyte concentrations were associated with incidence of hospitalizations due to HF. Methods and results-Leukocyte counts were measured in 16 940 men from the gene

Pikeperch Sander lucioperca trapped between niches: foraging performance and prey selection in a piscivore on a planktivore diet

The foraging behaviour of planktivorous pikeperch Sander lucioperca during their first growing season was analysed. Field data showed that S. lucioperca feed on extremely rare prey at the end of the summer, suggesting the presence of a bottleneck. In experiments, foraging ability of planktivorous S. lucioperca was determined when fish were feeding on different prey types (Daphnia magna or Chaoboru

Work above shoulder level and degenerative alterations of the rotator cuff tendons - A magnetic resonance imaging study

Objective. To determine whether work performed with the arms in a highly elevated position is associated with alterations in the rotator cuff tendons as assessed by magnetic resonance imaging (MRI). Methods. A cross-sectional study was performed in a historical cohort of male machinists, car mechanics, and house painters. The participants were right-handed, ages 40-50 years, and had been employed

Laplace's equation and the Dirichlet-Neumann map: a new mode for Mikhlin's method

Mikhlin's method for solving Laplace's equation in domains exterior to a number of closed contours is discussed with particular emphasis on the Dirichlet-Neutnann map. In the literature there already exit tyro computational modes for Mikhlin's method. Here a new mode is presented. The new mode is at least as stable as the previous modes. Furthermore, its computational complexity in the number of c

Can we define patients with no chance of survival after out-of-hospital cardiac arrest?

Objective: To evaluate whether subgroups of patients with no chance of survival can be defined among patients with out-of-hospital cardiac arrest. Patients: Patients in the Swedish cardiac arrest registry who fulfilled the following criteria were surveyed: cardiopulmonary resuscitation (CPR) was attempted; the arrest was not crew witnessed; and patients were found in a non-shockable rhythm. Settin

High-resolution genomic profiles of breast cancer cell lines assessed by tiling BAC array comparative genomic hybridization.

A BAC-array platform for comparative genomic hybridization was constructed from a library of 32,433 clones providing complete genome coverage, and evaluated by screening for DNA copy number changes in 10 breast cancer cell lines (BT474, MCF7, HCC1937, SK-BR-3, L56Br-C1, ZR-75-1, JIMTI, MDA-MB-231, MDA-MB-361, and HCC2218) and one cell line derived from fibrocystic disease of the breast (MCF10A). T

Monte Carlo evaluation of object shape effects in iodine-131 SPET tumor activity quantification

In our clinical iodine-131 single-photon emission tomography (SPET) quantification for radioimmunotherapy, calibration and partial volume correction are based on measurements with phantoms containing spheres to simulate patient tumors even though real tumors are frequently nonspherical. In this study, Monte Carlo simulation was used to evaluate how object shape influences "spill-out" and "spill-in
