A major oil spill in the Lofoten area during the spawning season can affect eggs, larvae and the spawning behaviour of mature fish. If possible, bigger fish

can escape a polluted area, but eggs and fish larvae are far less mobile [8]. With mature cod spawning in a concentrated area, a major oil spill could more easily overlap the whole distribution area of the resulting larvae [8] and possibly affect an entire yearclass of cod. Simulations of oil dispersal and the probability of various levels of population loss for several species of marine birds and mammals are presented in the Management plan, while improvements are requested on the consequences for fish species [8] and [28]. The current improvements include coupling an oil Avasimibe order dispersal model and a distribution model for Northeast Arctic cod eggs and larvae [42]. The simulated diurnal migration of larvae and Doxorubicin the refined modelling of vertical location of fish eggs are expected to improve the estimated exposure of larvae and eggs to toxic oil components [42]. Also, there are efforts to simulate the effects of egg and larvae mortality on the future cod stock [43]. These projects are financed by the Research Council of Norway and the petroleum sector [29], [42] and [43]. In spite of expected improvements, uncertainty will remain. The simulated overlap

between oil spill and mature cod, eggs and larvae is still uncertain. How much will the, partly unknown, diurnal pattern of larvae, moving up and down the water column, increase or decrease their chances of getting affected by an oil slick? How does cod in early life stages follow ocean currents? To what extent can mature cod avoid an oil slick? Species such as cod, and especially herring, have variable recruitment success between years. Typically a few

good yearclasses dominate the population, whereas most years produce only a moderate level of recruitment. This variability increases the potential harm that a spill in a single year can inflict on the stock [8]. And although spawning fish may avoid an oil spill, they may choose less favourable spawning old locations or the spawning ritual may be affected. It is also an open question whether the majority of the successful recruits come from only a few portions (limited in space and time) of the spawned eggs or whether there is a relatively homogenous contribution from different spawning sites and times [8]. An entire yearclass could potentially be killed although only a part of the spawning stock is affected. Further, the abundance of a stock and its distribution prior to a major oil spill will influence the impact of a major oil spill, but the abundance fluctuates significantly from one year to another, resulting in uncertain assessments and predictions, even before taking effects from an oil spill into account.

7, the resulting VIP or qualitative peaks used for such group discrimination were not only “dairy” products

but to a lesser degree also “beans and shellfish”. These were obviously particular deviation characteristics of the limited cohort used here. The great advantage of producing a statistical model is to be able to predict and test outcomes. Using the mathematical model produced by PLS (Fig. 7) the non-milk allergic control patients for instance all have shown a period < 2 years to achieve tolerance, regardless of their actual age. Likewise, the age of milk tolerance predicted for the patients that had achieved milk tolerance is very close to the actual measured age in the cross validation. Ideally, the model should be validated and its prediction error quantified with an external new test set. Due to the difficulty of acquiring suitable datasets and bearing in mind the intrinsic Belinostat cost limitations imposed by a retrospective study as the one presented here, the process of cross validation (for one iteration: leave at random 20% of samples out, predict with the other 80%, repeat until each sample has been left out, repeat for 17 iterations) was used both to estimate the model complexity (7 latent variables) as well as to estimate the error to be expected for new data.

This is still far from ideal but it sets the background for future studies where larger numbers, frequent monitoring, planned and controlled interventions would generate clearer and more accurate mathematical trends. The profiling GW-572016 mw array technique used in this work has shown that IgG and IgA share the same specificity whilst IgM and in particular IgE are distantly related. The correlation between specificity of

IgE and IgA is variable amongst the patients and cannot be used to predict atopy or the onset of tolerance to milk. The profiling technique has corroborated the clinical selection criteria for this cohort albeit it clearly indicated that 4 out of the 41 patients might have allergies other than from milk origin. There was also a good correlation between the array data and ImmunoCAP results. By using multivariate analysis and a particular PLEK2 retrospective cohort of clinically well characterized CMA children collected from patients in multiple visits, it was possible to produce statistical models to predict the onset of the tolerance to milk. These results, still in early stages of development, are encouraging and reinforce the potential use of multivariate models for prognostic analyses of complex profiling data.
