Mast A structural tower comprising one or more sections assembled in a horizontal position near the ground and then raised to the operating position. If the unit contains two or more sections, it may be telescoped or unfolded during the erection. 

Other GPCRs that positively influence FceRI-induced mast cell activation events include the receptors for prostaglandin E2 (the EP3 receptor), SIP (the SIP2 receptor). 

Mastocytosis is recognized in most patients because of the presence of characteristic cutaneous lesions [10]. A positive Darier s sign and/or histological examination of the skin using metachromatic stains, or by immunohistochemistry using antibodies to mast cell tryptase, helps confirm the diagnosis of cutaneous disease. 

More recently, the same group [13] found positive chymase staining in lung mast cells from postmortem samples after fatal anaphylactic drug reactions.

TRPVl also plays a central role in intercellular pro-inflammatory feedback loops. An important example is mast cells and sensory nerves. Mast cells release tryptase that, in turn, activates the protease-activated receptor PAR-2 activation of PAR-2 then opens TRPVl via PKC [50]. In keeping with this, PAR-2 agonists reduce the heat activation threshold of TRPVl from 42 °C to below body temperature [51]. Excited nerve endings release SP that, as a positive feedback, binds to neurokinin NKl receptors on mast cells. Mast cells also express TRPVl [52]. Consequently, endovanilloids can act in concert to stimulate mast cells and activate capsaicin-sensitive nerve endings. Of relevance is the finding that PAR-2 is up-regulated in the bladder during experimental cystitis [53]. 

Omalizumab is a recombinant humanized monoclonal anti-IgE antibody that inhibits binding of IgE to receptors on mast cells and basophils, resulting in the inhibition of mediator release and attenuation of the early- and late-phase allergic response. It may be a treatment option for moderate to severe persistent asthmatics 12 years of age or older whose asthma is not controlled by inhaled corticosteroids and who have a positive skin test or in vitro reactivity to perennial allergens.37 Omalizumab significantly decreases inhaled corticosteroid use, number and length of exacerbations, and increases asthma-related quality of life.37... 

Fig. 11.4. Model for cholinergic signalling in the intestinal mucosa, providing a possible rationale for AChE secretion by parasitic nematodes. ACh released from enteric cholinergic motor neurons stimulates chloride secretion, mucus secretion and Paneth cell exocytosis through muscarinic receptors. Secretory responses may be modulated by mast cell mediators, either directly or via the induction of neural reflex programmes. The role of muscarinic receptor-positive cells in the lamina propria of rats infected with N. brasiliensis is undetermined, as are potential mechanisms of trans-epithelial transport of the enzymes. Adapted from Cooke (1984).

Dietary copper deficiency increases the acute inflammatory response in rats and other small laboratory animals (Schuschke et al. 1994). The release of inflammatory mediators, such as histamine and serotonin, from mast cells increases the vascular permeability of postcapillary venules and results in edema. In copper-deficient rats, release of histamine from mast cells correlates positively with frequency of the acute inflammatory response. Copper-deficient rats (0.6 mg Cu/kg DW ration for 4 weeks) have more mast cells in muscle than copper-adequate controls given diets containing 6.3 mg Cu/kg DW ration however, histamine content of mast cells is not affected (Schuschke et al. 1994). An early clinical sign of copper deficiency is a reduction in the number of circulating neutrophils the mechanism for copper-deficient neutropenia (leukopenia in which... 

Potential therapeutic applications of host defense peptides also include the lantibiotic nisin. Indeed, nisin has had an impressive history as a food preservative with FDA approval in 1988 for use in pasteurized, processed cheese spreads. The attractiveness of nisin as a potential therapeutic is also enhanced due to its relative resistance to proteases and broad spectrum Gram-positive antimicrobial activity including multidrug-resistant strains. Biosynexus Inc. has licensed the use of nisin for human clinical applications and Immucell Corp. has licensed the use of Mast Out, an antimastitic nisin-containing product, to Pfizer Animal Health." Indeed, nisin formulations have been used as an active agent in the topical therapies Mast Out and Wipe-Out for bovine mastitis, an inflammatory disorder of the udder that is the most persistent disease in dairy cows." ... 

Ozone decay was measured in an office, a home, and several metal test facilities. Measurements were carried out with a Mast ozone meter and an MEC chemiluminescence ozone detector. The latter was calibrated with a stable ozone source and the epa neutral buffered potasaum iodide procedure. (It was noted over a wide range of concentrations that the mec meter measurements were consistently higher than those of the Mast meter by a factor of 1.3. That this is essentially identical with the findings of the DeMore committee is interesting.) Ozone generated by a positive corona ionizer was introduced into the test facilities. Ozone decay in a metal-walled room was found to be first-order, with the rate constant... 

The histamine- and leukotriene B4-releasing potential of the RCBPA P743 has been investigated in vitro on the RBL-2H3 mast cell line [25]. RBL-2H3 cells (with permission of Dr RP Siraganian, National Institutes of Health, Bethesda, MD, USA) were replated on Eagle s minimum essential medium and incubated for 30 minutes at 37 °C in 5% CO2 with the test-solutions. Calcium ionophore A23187 was used as a positive control. The viability of mast cells was determined by means of a quantitative colorimetric assay that is based on the abiUty of viable cells to cleave the reagent MTT [33].
