Canaries, finches, starlings and mynahs are examples of passerine birds that are common in cap- tivity. Passerines are widely distributed throughout the world, and all passerines share a common aniso- 43 dactyl foot structure with three unwebbed toes pointed cranially and one caudally. The order is believed to have originated in Gond- wana, the ancient southern continent. One group of passerines is now believed to have evolved and radiated in eastern Gondwana, proto-Australasia (these include such species as bow- erbirds, lyrebirds, birds of paradise, honeyeaters, Australian grass finches and fairy wrens). Another group, the suboscines or primitive songbirds are be- lieved to be of western Gondwanan origin (current- Patricia Macwhirter day South America). These include such primitive South American species as contingas, manikins, ant- birds and gnateaters. More advanced songbirds like Fringillidae finches, sparrows, warblers, starlings, thrushes and sunbirds may also have evolved via western Gondwana and migrated from this area to become widely distributed. The anatomic and physiologic Finches) normally have characteristic luminous differences expressed within the order reflect these mouth markings.

On the other hand order methotrexate 2.5 mg line, some laboratories modify the assay in order to work with a higher sensitivity cheap methotrexate 2.5mg free shipping. Therefore, in future it is intended to standardize the methodology in this lower working range. It provides results with an improved comparability between the laboratories con­ cerned. Essential pre­ conditions for our system are uniform methods and the use of uniform control sera. For each participating laboratory the mean bias (with respect to the consensus mean) and the mean imprecision (from results of hidden replicates) have been computed from data accumulated over six-month periods; the average bias and imprecision of all participants are 10. The accumulated data have also been analysed to evaluate the analytical reliability of method kits most used by the participants in the interlaboratory survey. Moreover, the data collected from the interlaboratory surveys can be employed to evaluate the reliability of the method kits used by the laboratories [3, 6, 7]. The results of each dispatch are entered into a computer and processed to prepare a monthly report (Fig. All results accumulated during a six-month period are used to prepare and end-of- period report in which the mean bias and the mean imprecision achieved by each participating laboratory are reported. The number of participants ranged from 19 (1st dispatch) to 153 (19th dispatch); the percentage of returned results was 85—90%. The validity of the consensus mean as reference value has been verified by recovery experiments. The time behaviour of the between-laboratory agreement for T3 and T4, shown in Fig. The mean bias and imprecision achieved by the eight considered method kits are reported in Fig. Тъ(а) and Тц(Ъ): Comparison o f the analytical performances o f the eight method kits more used by the participants in the survey. The serum samples containing these hormones are dispatched monthly to about 100 Italian laboratories. The returned results are used to prepare monthly and end-of period (every semester) reports. The former contain an interlaboratory variability estimate, the latter the estimates for each participant of mean precision and mean bias. The returned results are computer-processed to prepare a monthly report containing the histogram of all data and related statistical parameters [ 1]. Every semester we produce an end-of-period report including estimates of mean precision (computed from hidden replicates), mean bias (computed with respect to the consensus mean) and a bias-precision plot [1]. Before their dispatch the pools are defrosted to prepare the samples which are sent in liquid state. The samples are demonstrated to be stable at room temperature for at least a week. International reference preparations for protein hormones The kit standards used by the laboratories differ and are calibrated against different international reference preparations. To compare the results of the various laboratories it was necessary to apply the same reference preparations to all of them. We transcribed the results in terms of these preparations by conversion factors obtained from the kit producers. For cortisol and progesterone we did not take into account the pool sent three times because its concentration —about 2 pg/ 100 mL for cortisol and 1 ng/mL for progesterone — was near the sensitivity of most direct kits used. The hormone concentrations are expressed in ng/mL for progesterone, in pg/mL for estradiol, in ng/100 mL for testosterone, and in ^tg/100 mL for cortisol. The main problem was the use of a different reference preparation for protein hormones. Regarding other steroid hormones the laboratories use classic steroid methods (with serum extraction and tritiated tracers) and direct methods, or with iodinated tracers. Classic techniques are affected by methodological difficulties; and the other methods present problems such as low sensitivity and specificity. Quality assurance for steroid receptor assays has to be considered sui generis, primarily because purified material as a proper reference standard is not yet available and, secondly, because of sample heterogeneity and receptor thermolability. Research Treatment of Cancer), only on lyophilized cytosol of target tissue (calf uterus). Variation coefficients of E2 R concentrations in fM/mL for the three positive samples ranged from 33. Five out of 15 laboratories estimated as “positive” the negative sample (only one of the most experienced laboratories had a false positive result). Since lyophilized preparations were obtained by scalar dilutions, it was possible to make a variance analysis for each laboratory’s linear regression, and of the mean values of all laboratories. The regression coefficient of each laboratory is highly significant; the regression of mean values of E2 R(fM/mL) is in excellent agreement with the theoretical scalar dilutions, with highly significant coefficients (0.
