Aerobic exercise in young adults can induce vascular plasticity in the hippocampus, a critical region for recall and recognition memory. In a mechanistic proof-of-concept intervention over 3 months, we investigated whether healthy older adults (60-77 years) also show such plasticity. Regional cerebral blood flow (rCBF) and volume (rCBV) were measured with(More)
OBJECTIVE To study the influence of long-term volume therapy with different solutions and continuous administration of pentoxifylline on plasma concentrations of circulating adhesion molecules. DESIGN Prospective, randomized study. SETTING A surgical intensive care unit (ICU) of a university hospital. PATIENTS Forty-two patients with sepsis secondary(More)
Significantly improved crop varieties are urgently needed to feed the rapidly growing human population under changing climates. While genome sequence information and excellent genomic tools are in place for major crop species, the systematic quantification of phenotypic traits or components thereof in a high-throughput fashion remains an enormous challenge.(More)
BACKGROUND Despite clear differences in clinical presentation and outcome, squamous cell carcinomas of the head and neck (SCCHN) arising from human papilloma virus (HPV) infection or heavy tobacco/alcohol consumption are treated equally. Next-generation sequencing is expected to reveal novel targets for more individualised treatment. PATIENTS AND METHODS(More)
Globally, over 7.4 million accessions of crop seeds are stored in gene banks, and conservation of genotypic variation is pivotal for breeding. We combined genetic and biochemical approaches to obtain a broad overview of factors that influence seed storability and ageing in barley (Hordeum vulgare). Seeds from a germplasm collection of 175 genotypes from(More)
An efficient immune response against hepatitis C virus (HCV) is necessary to clear infection. As HCV is a single-stranded RNA virus, a role for TLR7 in the immune response against HCV is possible, and early clinical studies have demonstrated an antiviral effect of TLR7 stimulation. We tested the hypothesis that genetic variations of TLR7 are associated with(More)
Worldwide germplasm collections contain about 7.4 million accessions of plant genetic resources for food and agriculture. One of the 10 largest ex situ genebanks of our globe is located at the Leibniz Institute of Plant Genetics and Crop Plant Research in Gatersleben, Germany. Molecular tools have been used for various gene bank management practices(More)
Tetramic acid derivatives are an important class of nitrogen heterocycles with a pyrrolidine-2,4-dione core as a key structural motif. From the sponge-derived fungus Beauveria bassiana, a new equisetin-like tetramic acid derivative, beauversetin (1), was isolated. The sea weed-derived fungus Microdiplodia sp. produced the tetramic acid derivative 2(More)
We assessed the risk and determined predictors of early epileptic seizures (ES) in patients with acute cerebral venous and sinus thrombosis (CVST). A prospective series of 194 consecutive patients with acute CVST admitted to neurological wards in two German university hospitals was analysed for frequency of ES and in-hospital mortality. Demographic,(More)
PURPOSE To evaluate functional MR imaging in patients with rheumatoid arthritis (RA) involving the cervical spine. MATERIAL AND METHODS We used a device that allows MR examination to be made of the cervical spine in infinitely variable degrees of flexion and extension. Dynamic functional MR imaging was performed on 25 patients with RA. RESULTS(More)
