High-grade gliomas are one of the most aggressive human tumors with <1% of patients surviving 5 years after surgery. Immunotherapy could offer a possibility to eradicate remnant tumor cells after conventional therapy. Experimental immunotherapy can induce partial cure of established intracerebral tumors in several rodent models. One reason for the limited therapeutic effects could be immunosuppres
OBJECTIVES: To analyse survival rates and the causes of death in a systemic sclerosis (SSc) population, and to evaluate the occurrence of fatal malignant neoplasms and their possible association with oral cyclophosphamide (CYC) treatment. METHODS: Survival was calculated for 249 SSc patients followed up for up to 13 years. Mean (SD) follow up was 5.8 (4.2) years. The 49 decreased patients were sub
We present a novel method for monitoring isothermal lipid hydration using a sorption microcalorimeter. A measuring cell of the double-twin calorimeter consists of two vessels connected by a stainless steel tube. The upper vessel contains pure water, and the bottom vessel is loaded with the lipid sample. This calorimeter allows for simultaneous measurement of the partial molar enthalpy and the chem
Label-free LC-MS analysis allows determining the differential expression level of proteins in multiple samples, without the use of stable isotopes. This technique is based on the direct comparison of multiple runs, obtained by continuous detection in MS mode. Only differentially expressed peptides are selected for further fragmentation, thus avoiding the bias toward abundant peptides typical of da
Despite a lack of randomized trials, practice guidelines recommend that mild induced hypothermia be considered for comatose survivors of in-hospital cardiac arrest. This study describes the safety, feasibility, and outcomes of mild induced hypothermia treatment following in-hospital cardiac arrest.
Total N-2 S-branch broadening coefficients have been measured in situ as a function of radial position in a highly sooting ethylene diffusion flame by the use of time-resolved dual-broadband picosecond pure rotational CARS (RCARS). Time-domain measurements of the J-dependent N-2 rotational coherence decays in the flame were used to determine the broadening coefficients, and these coefficients were
In the Peyer's patches (PPs), germinal centers (GCs) are chronically induced by bacteria and are the major sites for generation of gut immunoglobulin A (IgA) immune responses. Whether follicular dendritic cells (FDCs) within the GCs directly contribute to the IgA production in PPs is unknown. We showed here that direct stimulation of FDCs by bacterial products and retinoic acid synergistically enh
The innate immune system is the first line of defense against invading microbes. Its specificity relies a great deal on host pattern recognition molecules that sense pathogen-associated molecular patterns of the invading pathogen. However, full protection is not always guaranteed, and some early defense mechanisms involved in bacterial killing, such as the complement system, can also exert cytolyt
We show that collisions with stellar-mass black holes can partially explain the absence of bright giant stars in the Galactic Centre, first noted by Genzel et al. We show that the missing objects are low-mass giants and asymptotic giant branch stars in the range 1-3 M-circle dot. Using detailed stellar evolution calculations, we find that to prevent these objects from evolving to become visible in
Fimbriae target bacteria to different mucosal surfaces and enhance the inflammatory response at these sites. Inflammation may be triggered by the fimbriae themselves or by fimbriae-dependent delivery of other host activating molecules such as lipopolysaccharide (LPS). Although LPS activates systemic inflammation through the CD14 and Toll-like receptor 4 (TLR4) pathways, mechanisms of epithelial ce
Positional cloning of the underlying genes for the rare syndrome autoimmune polyendocrinopathy candidadiasis extrodermal dystrophy (APECED) opened a new venue of research on the role of central tolerance in autoimmunity. The associated autoimmune regulator gene (AIRE), was found to be expressed in medullary thymus epithelial cells (mTEC) in both man and mice, and to control promiscuous expression
We discuss the age of the stellar disks in the solar neighborhood. After reviewing the various methods for age dating, we discuss current estimates of the ages of both the thin- and the thick disks. We present preliminary results for kineymatically-selected stars that belong to the thin- as well as the thick disk. All of these dwarf and sub-giant stars have been studied spectroscopically and we ha
In order to maximize protein identification by peptide mass fingerprinting noise peaks must be removed from spectra and recalibration is often required. The preprocessing of the spectra before database searching is essential but is time-consuming. Nevertheless, the optimal database search parameters often vary over a batch of samples. For high-throughput protein identification, these factors shoul
Public health policies in most European countries are concerned with how to keep older people living independently with a qualitatively good life in the community as long as possible. However, knowledge about what may characterise those seemingly 'healthy' older people is sparse. The aim of the study was to investigate the characteristics of a sample of people (75+) reporting various degrees of Qu
Insertions and deletions of entire codons have recently been discovered as a mechanism by which B cells, in addition to conventional base substitution, evolve the antibodies produced by their immunoglobulin genes. These events frequently seem to involve repetitive sequence motifs in the antibody-encoding genes, and it has been suggested that they occur through polymerase slippage. In order to bett
