BACKGROUND/AIMS It remains elusive whether there is a crosstalk between Smad and mitogen-activated protein kinases (MAPKs) and whether it regulates cyclosporine A (CyA)-induced apoptosis in renal proximal tubular cells (RPTCs). METHODS The effect of CyA on nuclear translocation of Smad2/3 and MAPKs (measured by Western blotting or immunofluorescence) and(More)
BACKGROUND Cow's milk allergy is one of the most common food allergies among younger children. We investigated IgE antibodies to milk, and IgE and IgG4 antibodies to casein, α-lactalbumin and β-lactoglobulin in cow's milk allergic (CMA) and non-allergic (non-CMA) children in order to study their clinical usefulness. METHODS Eighty-three children with(More)
The olfactory system can be a toxicological target of volatile organic compounds present in indoor air. Recently, 2-ethyl-1-hexanol (2E1H) emitted from adhesives and carpeting materials has been postulated to cause “sick building syndrome.” Patients’ symptoms are associated with an increased sense of smell. This investigation aimed to characterize the(More)
Blood samples were collected 25 yr ago from hand-arm vibration syndrome patients with vibration-induced white finge/VWF (VWF+ group) and without it (VWF- group), and healthy controls (n=12 in each group), and stored at -80 °C. The subjects provided venous blood twice: at baseline, and after cold exposure at 7 °C for 25 min. Blood specimens were analyzed for(More)
Lipopolysaccharide (LPS) is associated with the development and exacerbation of airway inflammation. Increases in innervation of sensory C-fibers and tachykinin receptors, which mainly involve overproduction of neurotrophins such as nerve growth factor (NGF), may enhance neurogenic inflammation. Expression of NGF and its receptors in rat lungs is known to(More)
