Effects on drainage of the mediastinum and pleura during negative pressure wound therapy when using a rigid barrier to prevent heart rupture.

Right ventricular heart rupture is a devastating complication associated with negative pressure wound therapy (NPWT) following cardiac surgery. The use of a rigid disc has been suggested to offer protection against this lethal complication by preventing the heart from being drawn up towards, and damaged by, the sharp sternum edges. The aim of the present study was to compare the wound fluid evacua

Aggrecanase cleavage in juvenile idiopathic arthritis patients is minimally detected in the aggrecan interglobular domain but robust at the aggrecan C-terminus.

OBJECTIVE: To understand aggrecan degradation in juvenile idiopathic arthritis (JIA), the pattern and abundance of aggrecan fragments in synovial fluid aspirates from JIA patients were analysed and compared with aggrecan fragments in synovial fluids from patients with other arthritides, juvenile knee injury and a knee-healthy reference group. METHODS: The concentration of sulphated glycosamino

Identification of ubiquitin in bovine milk and its growth inhibitory effects on human cancer cell lines.

Bovine milk is associated with improved health and reduced risk of several diseases, among them cancer. Milk is a complex mixture of known and unknown components. The components and the mechanisms that contribute to the cancer-preventive effects are largely unknown. We set out to find new peptides in milk and identified ubiquitin (Ub) using matrix-assisted laser desorption ionization-time of fligh

Standing-wave Acoustic Trap For Nonintrusive Positioning of Microparticles

A nonintrusive three-dimensional trap for microscopic particles in a Liquid is described. The trap is based on acoustic radiation forces in an ultrasonic confocal standing-wave cavity. Experiments at 11 MHz demonstrate the concept and verify the theoretically calculated forces. Theoretical calculations for higher-frequency systems indicate a significant potential for low-rms-displacement trapping

von Willebrand's disease: a report from a meeting in the Åland islands.

von Willebrand's disease (VWD) is probably the most common bleeding disorder, with some studies indicating that up to 1% of the population may have the condition. Over recent years interest in VWD has fallen compared to that of haemophilia, partly the result of focus on blood-borne diseases such as HIV and hepatitis. Now the time has come to revisit VWD, and in view of this some 60 international p

Cell factory-derived bioactive molecules with polymeric cryogel scaffold enhance the repair of subchondral cartilage defect in rabbits.

We have explored the potential of cell factory-derived bioactive molecules, isolated from conditioned media of primary goat chondrocytes, for the repair of subchondral cartilage defects. Enzyme-linked immunosorbent assay (ELISA) confirms the presence of transforming growth factor-β1 in an isolated protein fraction (12.56 ± 1.15 ng/mg protein fraction). These bioactive molecules were used alone or

Genomic profiling of chondrosarcoma: chromosomal patterns in central and peripheral tumors.

PURPOSE: Histologic grade is currently the best predictor of clinical course in chondrosarcoma patients. Grading suffers, however, from extensive interobserver variability and new objective markers are needed. Hence, we have investigated DNA copy numbers in chondrosarcomas with the purpose of identifying markers useful for prognosis and subclassification. EXPERIMENTAL DESIGN: The overall pattern o

Structure-Immune Response Relationships of Hapten-Modified Collagen II Peptides in a T-Cell Model of Allergic Contact Dermatitis.

Allergic contact dermatitis (ACD) is mediated by T cells that specifically recognize hapten-modified peptides. T cells are known to recognize antigens as short processed peptides bound to major histocompatibility complex (MHC) molecules on the surface of antigen-presenting cells (APC). It has previously been demonstrated that T cells can specifically recognize carbohydrates on the lysine at positi

Adsorption behavior of statherin and a statherin peptide onto hydroxyapatite and silica surfaces by in situ ellipsometry.

The salivary protein statherin is known to adsorb selectively onto hydroxyapatite (HA), which constitutes the main mineral of the tooth enamel. This adsorption is believed to be crucial for its function as an inhibitor of primary (spontaneous) and secondary (crystal growth) precipitation of calcium phosphate salts present in saliva. A fragment corresponding to the first 21 N-terminus amino acids o

The role of CD1d-restricted NK T lymphocytes in the immune response to oral infection with Salmonella typhimurium.

CD1d-restricted natural killer T (NKT) cells belong to the innate-like lymphocytes which respond rapidly to stress and infectious challenge. We have studied murine CD1d-restricted NKT cells in the early immune response to virulent Salmonella enterica serovar Typhimurium after oral infection. In the liver and spleen, neutrophil and macrophage numbers had increased several-fold by day 5 post-infecti

Infratentorial progressive multifocal leucoencephalopathy (PML) in a patient with SLE (2008: 4b).

Progressive multifocal leucoencephalopathy (PML) is a viral infection occurring in immunocompromised patients. The typical magnetic resonance imaging (MRI) findings include supratentorial asymmetric nonenhancing white matter lesions without mass effect. We present a patient with progressive cerebellar and brain stem lesions, emphasizing the fact that the diagnosis of PML should be considered also

Chiral Separation of Amino Acids by Ligand-Exchange Electrochromatography Using Continuous Beds

A chiral ligand-exchange phase for capillary electrochromatography based on continu-ous bed technology was developed. The chiral stationary phase is prepared by a one- step in situ copolymerization procedure using methacrylamide, piperazine diacryla- mide, vinylsulfonic acid and N-(2-hydroxy-3-allyloxypropyl)-L-4-hydroxyproline. These chiral continuous beds are inexpensive and easy to prepare. The

Cancer: More of polygenic disease and less of multiple mutations? A quantitative viewpoint.

The focus of cancer research is on cancer-specific mutations, with most clinical trials involving targeted drugs. Huge numbers of DNA lesions and tumor resistance events, in each of the >10(13) cells of a human individual, form a striking contrast to the low, and also very narrow, cancer incidence window (10(-1)-10(0)). A detailed consideration of these quantitative observations seems to question

Cognitive manic symptoms associated with the P2RX7 gene in bipolar disorder.

Objective: Several genetic loci have been suggested to be associated with bipolar disorder but results have been inconsistent. Studying associations between bipolar symptoms and candidate genes may better expose this relationship. Here we investigate the association between bipolar key symptoms and the P2RX7 gene. Methods: Key symptoms of mania were rated in two sets of medicated bipolar disorder

Staphylococcus aureus induced clotting of plasma is an immune evasion mechanism to persist within the fibrin network.

Recent work has shown that coagulation and innate immunity are tightly interwoven host responses that help eradicate an invading pathogen. Some bacterial species including Staphylococcus aureus secrete pro-coagulant factors that in turn can modulate these immune reactions. Such mechanisms may not only protect the microorganism from a lethal attack, but also promote bacterial proliferation and the

Photodynamic therapy: superficial and interstitial illumination.

Photodynamic therapy (PDT) is reviewed using the treatment of skin tumors as an example of superficial lesions and prostate cancer as an example of deep-lying lesions requiring interstitial intervention. These two applications are among the most commonly studied in oncological PDT, and illustrate well the different challenges facing the two modalities of PDT-superficial and interstitial. They thus
