The interleukin-1 (IL-1) pro-inflammatory cytokine family participates in inflammatory processes and vessel damage involved in neurodegeneration. Recent studies suggest that Alzheimer's disease (AD) and vascular dementia (VaD) may share genetic risk factors. In this study, the frequency of polymorphisms in the genes coding for interleukin (IL)-1alpha,(More)
The transforming growth factor-beta1 (TGF-beta1) is involved in post-ischemic neuronal rescue and in beta-amyloid turn-over. We hypothesized that the risk for dementia and related neuropathologies is modified by the TGF-beta1 functional genetic variants. The association of the TGF-beta1+29T-->C polymorphism with dementia was examined in a sample of 261(More)
Respiratory sensitization can be caused by a variety of substances at workplaces, and the health and economic burden linked to allergic respiratory diseases continues to increase. Although the main factors that affect the onset of the symptoms are the types and intensity of allergen exposure, there is a wide range of interindividual variation in(More)
BACKGROUND Incorporating the influence of genetic variation in the risk assessment process is often considered, but no generalized approach exists. Many common human diseases such as asthma, cancer, and cardiovascular disease are complex in nature, as they are influenced variably by environmental, physiologic, and genetic factors. The genetic components(More)
Objective—To investigate the association between single nucleotide polymorphisms (SNPs) located across the major histocompatibility complex and susceptibility to diisocyanate-induced asthma (DA). Methods—The study population consisted of 140 diisocyanate-exposed workers. Genotyping was performed using the Illumina GoldenGate major histocompatibility complex(More)
Ortho-Phthalaldehyde (OPA) has been approved for high-level sterilization of heat-sensitive medical instruments and is increasingly being used as a replacement in the healthcare industry for glutaraldehyde, a known sensitizer. Numerous case reports have been published indicating workers and patients experiencing respiratory problems, anaphylaxis, skin(More)
