Allergy is a very common problem and can be a handicap in everyday life, specially when symptoms occur at work place. Some persons working with drosophila developed respiratory symptoms. Investigators tried to analyze if these manifestations could be due to a specific allergy to drosophila.
In areas of seasonal malaria transmission, treatment of carriers of malaria parasites, whose parasitaemia persists at very low levels throughout the dry season, could be a useful strategy for malaria control in areas with a short transmission season. We did a randomized trial to compare two regimens for clearance of low level parasitaemia in the dry season.
The overarching goal of this multi-disciplinary research program is to develop and optimize new cross-species translational assessments of reward and cognition that will not only be assessed in parallel in humans and rats, but also produce neurophysiological and behavioral metrics that can be objectively compared across species. The research will build on prior studies by further developing and optimizing (in Phase 1), then validating via pharmacological challenge (in Phase 2),...
This is a Phase 2, randomized, double-blind study in which motavizumab (MEDI-524) and palivizumab will be administered to high-risk children during the same respiratory syncytial virus (RSV) season. It is anticipated that approximately 240 children (80 in each group) will be enrolled from the southern hemisphere during the upcoming RSV season (2006).
Bacillus species are ubiquitous gram-positive spore-forming organisms. They rarely cause disease in the immunocompetent and are more frequently isolated as a culture contaminant. However, Bacillus Species can cause severe systemic infections in immunocompromised patients including preterm infants. The purpose of this study is to identify the risk factors of these infections.
Diabetic nephropathy has become the single most frequent cause of end-stage renal disease. On a molecular level, at least five major pathways have been implicated in glucose-mediated vascular and renal damage and all of these could reflect a single hyperglycaemia-induced process of overproduction of reactive oxygen species. Recent studies have shown that inflammation, and more specifically pro-inflammatory cytokines play a determinant role in the development of micro- vascula...
The malaria parasite Plasmodium falciparum remains at sub-patent level throughout the dry season in areas of seasonal malaria transmission. Targeting this parasite reservoir before the transmission season could be a good strategy for malaria control. We are conducting a randomized double blind placebo controlled mass drug administration trial in eight village to clear the dry season low level parasitaemia with an ultimate aim of controlling malaria in eastern Sudan.
The purpose of this study is to determine whether the mix of microbial species isolated from biofilm-clogged voice prostheses is specific to each participant, whether the microbes are orally-derived and whether the presence of specific species is a predictor of the frequency with which patients discard devices due to malfunction. The microbes isolated from discarded devices will be used to test the antimicrobial properties of newly-developed medical silicones.
The overall objective of this clinical study is to determine if smokers who switch from their usual high reactive oxygen and nitrous oxide species (ROS/NOS) products to a low ROS/NOS product exhibit increased or decreased levels of oxidative stress/damage, respectively.
The winter break within the German Professional Football Leagues will be shortened as for the season 2009/2010 from 6.5 to 3.5 weeks. That might have repercussions on injury incidence in either way, positive or negative. On the one hand, recovery time during the winter will be shorter, which might lead to an increased risk of injury. On the other hand, it will allow a better spread of games in the second round, thus reducing the amount of the so-called "English weeks", which i...
The objective of this proposal is to determine the effects of footwear stiffness on a large cohort of high school football players during a football season. The investigators expect that functional athlete groups will be developed, based on subject specific assessments (biomechanical, morphological, performance, comfort), and lead to important translational findings that may impact footwear modification and recommendation to a population of American football players. Two standa...
This study will look for links between corn farming practices and short-term changes in immune function in farmers throughout the growing season. It will examine biologic effects associated with specific pesticide exposures and general planting activities, such as tillage. Farmers have an increased risk of non-Hodgkin s lymphoma and certain other blood cancers such as multiple myeloma and leukemia, but the reasons for this increase have not been identified. Findings of this s...
The aim of the study is to investigate the effect of inhaled apocynin on ROS (reactive oxygen species) and NOS (reactive nitrogen species) synthesis in 10 nonsmoking mild asthmatics. Effects of nebulized apocynin (0.5 mg/ml, 6 ml) are assessed in exhaled breath condensate (EBC) after 30, 60 and 120 minutes.
The purpose of this study is to find out if the bacteria present in the nose or sinuses of people with seasonal allergies changes during their allergy season. Another purpose of this study is to see if the bacteria present in the nose and sinuses of non-allergic people are the same as allergic people before the allergy season and if it changes during the season. Many bacteria are difficult to grow in the laboratory so the investigators are using analysis of DNA (the genetic ma...
The aim of the study is to evaluate the efficacy of ciclesonide in patients with persistent asthma over 3 months, especially in the cold season. Ciclesonide will be inhaled by a metered-dose inhaler. The study will provide further data on safety and tolerability of ciclesonide.
The purpose of this study is to use ultrasound imaging to determine if there are certain frequencies, durations, and intensities of baseball pitching that expose a college baseball player to increased risk of injury to their ulnar collateral ligament of their elbow throughout one baseball season.
Repeated blood sampling within a regular soccer season of German first league clubs shall serve to define soccer-specific reference values for routine parameters determined from venous blood. It was hypothesized that only for a minor number of parameters common reference values will have to be adapted for soccer players during their competitive season.
Deep ocean mineral water has been shown to improve exercise phenotypes in human and animal models. However, there is yet to be an investigation of Algae species such as Lithothamnion that absorb and concentrate these minerals. Therefore, the AAP trial will investigate the effect of water soluble Lithothamnion species on exhaustive exercise-induced blood lactate accumulation, recovery and power output in trained cyclists.

Severe anaemia is a frequent cause of admission to hospitals in tropical Africa and about 10% of such children die. In endemic countries, anaemia has multiple causes such as nutritional deficiencies, infections and haemoglobinopathies. However, Plasmodium falciparum infection is believed to be the major contributory factor to the aetiology of severe anaemia. Severe anaemia is usually treated by blood transfusion although transfusion carries the attendant risk of transmission of...
RLIP76 (Ral binding protein1) is a 76 kDa splice variant protein encoded by the human gene (RALBP1, 18p11.22). It is a multifunctional modular protein found ubiquitously from Drosophila to humans, in cells ranging from red blood cells to endothelial cells of the brain. Its expression more predominant in breast, heart, liver and less so in colon and brain parenchyma.
This study will be the first assessment of the efficacy of MEDI7510 for the prevention of RSV disease. It will also provide estimates of vaccine efficacy and of endpoint incidence in the placebo arm. It will also assess the safety and immunogenicity of concurrent dosing of MEDI7510 and IIV to expand on the observations made in the Phase 1b study of MEDI7510. It will also expand the safety database of subjects dosed with MEDI7510. The study will also assess the immune response ...
The human oral cavity is a diverse habitat that contains approximately 700 prokaryotic species. The oral microbiome is comprised of 44% named species, 12% isolates representing unnamed species, and 44% phylotypes known only from 16S rRNA based cloning studies (http://www.homd.org/). Species from 11 phyla have been identified: Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria, Spirochaetes, Fusobacteria, TM7, Synergistetes, Chlamydiae, Chloroflexi and SR1 (http://www.hom...
