The Th2 cytokines IL-4 and IL-13 mediate allergic pulmonary inflammation and airways hyperreactivity (AHR) in asthma models through signaling dependent upon the IL-4 receptor-alpha chain (IL-4Ralpha). IL-13 has been further implicated in the overproduction of mucus by the airway epithelium and in lung remodeling that commonly accompanies chronic(More)
Gout is an acute rheumatic disorder that occurs in connection with the deposition of monosodium urate (MSU) crystals in the joints. This disease is characterized by intermittent episodes of severe pain and inflammatory joint swelling which are seemingly driven by prostaglandins. In this study we investigated the effect of MSU crystals on arachidonic acid(More)
Pregnant cows immunized with cholera enterotoxin produce an immunoglobulin G class 1 antibody that enters the colostrum in high titer. After exposure to intestinal enzymes, this antibody remains immunologically reactive and inhibits intestinal fluid secretion in infant and adult rabbits exposed to cholera enterotoxin. Specific bovine colostral antibodies(More)
The B7-family molecule CD86, expressed on the surface of pulmonary and thoracic lymph node antigen-presenting cells, delivers essential costimulatory signals for T-cell activation in response to inhaled allergens. CD86-CD28 signaling is involved in priming allergen-specific T cells, but it is unclear whether these interactions play a role in coordinating(More)
Neuromuscular respiratory failure is the cause of death in the majority of patients with ALS. Respiratory muscle dysfunction impacts on quality of life and survival. Attentive management of respiratory muscle weakness is an important aspect of the management of the ALS patient. The respiratory muscles may be thought of as four functional groups: the(More)
We report the results of a randomized comparison of two intravenous safflower oil (fat) emulsions in neonates who required total parenteral nutrition. The fat emulsions differed only in their content of alpha-linolenic acid: in one emulsion the alpha-linolenic acid content of the oil was 0.1% of fatty acids, while in the other emulsion the alpha-linolenic(More)
