Animal productions are the results of interactions between the genetic potential of the animal, environmental factors and nutrient supplies. These interactions modulate the endocrine system, especially the somatotrope axis. IGFBP-3 is the major carrier of the IGFs (the main growth-promoting peptide) in plasma circulating as part of a 150 kDa ternary complex with one IGF peptide and a single acid-labile subunit. The IGFBP-3 purification would allow the measure of the changes in plasma IGFBP-3 throughout the day and the development and in various physiological situations. We try to purify the bovine IGFBP-3. Firstly, we load 0,5 ml of serum onto an Hiload 16/6 Superdex 200 prep grade column, then onto an ion exchange column and finally onto an IGF-I affinity column. The purification fails perhaps because the sample is to small. Secondly, 5 ml of serum is fractionated by 3 gel filtrations. Between the first and the second filtration, the fractions containing IGF-I binding activity are pooled and concentrated. Before the third gel filtration, the fractions containing this activity are pooled anew, acidified with HCl and incubated at 4 °C for 2 hours. The third gel filtration fractions are pooled and subjected to an heparin-affinity chromatography. The elution pic shows only IGFBP-3 activity. In conclusion, our purified product contains other proteins. But the ternary complex is dissociated, so an IGF-I affinity chromatography would purify the IGFBP-3 from the elution pic of the heparin-affinity column. [less ▲]

BACKGROUND: The coexistence of malignancies close to each other on the skin has been occasionally reported. The concept of field cancerogenesis applies to such cases. Given the purported mechanism of action of imiquimod, it should not be surprising that this treatment could inhibit epidermal field cancerogenesis. AIM: To assess the effect of imiquimod applied twice weekly on incipient bowenoid changes disclosed in the vicinity of basal cell carcinomas. MATERIALS AND METHOD: Biopsies were taken before treatment and after 4-6 weeks and 12 weeks of imiquimod treatment. RESULTS: Large atypical bowenoid keratinocytes and dyskeratotic cells were cleared in time while factor-XIIIa-positive dermal dendrocytes appeared boosted and admixed with a brisk lymphocytic infiltration. CONCLUSION: Epidermal field cancerogenesis appears to be controlled by imiquimod. Dermal dendrocytes might play a pivotal role in this regression phenomenon. [less ▲]

The paper discusses the components of reduction factor to be accounted for design purposes. A parametric study of moment resisting steel frames (MRSF) designed according Eurocode 3 (EC3) and Eurocode 8 (EC8) is performed. The structural supply of the designed structures exceeds largely the seismic demand in spite of the fact that Ultimate Limit State (ULS) verification of EC8 for MRSF is not conservative. The structural performance is poorly correlated with ULS verification of EC8 but with others code restrains and with parameters like base shear ratio or fundamental period. The practice that deduces the values of reduction factor on the observation of structural performance under past earthquake is not rationally based. This practice tends to make useless the ULS verification for structural systems like MRSF, in which structural performance is poorly correlated with the ULS verification. This practice is responsible of the unsafe values of reduction factors assigned in the seismic codes. [less ▲]

A six-year-old, male dobermann was presented with a history of dyspnoea and bouts of coughing. Radiography and computed tomography of the thorax showed pleural effusion and a well-circumscribed, calcified mass of 10 cm in diameter, appearing to originate from the left first rib. Thoracocentesis revealed that the pleural fluid was chylous in nature. An inclsional biopsy was performed, which gave a histological diagnosis of chondroma. Resolution of the chylothorax after en-bloc surgical removal of the tumour suggested that the rib tumour was the initiating cause of the chylothorax. Seventeen months later, rib neoplasia recurred without pleural effusion, and was removed successfully. To the authors' knowledge, rib chondroma, which is an unusual tumour in dogs, has not been previously documented as a cause of chylothorax. [less ▲]

Time series of wind-stress data, AVHRR and SeaWiFS satellite images, and in situ data from seven cruises are used to assemble a coherent picture of the hydrographic variability of the seas off the Northwest Iberian Peninsula from the onset (September-October) to the cessation (February-May) of the Portugal coastal counter current (PCCC). During this period the chemistry and the biology of the shelf, slope and ocean waters between 40degrees and 43degreesN have previously been undersampled. Novel information extracted from these observations relate to: 1. The most frequent modes of variability of the alongshore coastal winds, covering event, seasonal and long-term scales; 2. The conspicuous cycling between stratification and homogenisation observed in PCCC waters, which has key implications for the chemistry and biology of these waters; 3. The seasonal evolution of nitrite profiles in PCCC waters in relation to the stratification cycle; 4. The Redfield stoichiometry of the remineralisation of organic matter in Eastern North Atlantic Central Water (ENACW)-the water mass being transported by the PCCC; 5. The separation of coastal (mesotrophic) from PCCC (oligotrophic) planktonic populations by a downwelling front along the shelf, which oscillates to and fro across the shelf as a function of coastal wind intensity and continental runoff; and 6. The photosynthetic responses of the PCCC and coastal plankton populations to the changing stratification and light conditions from the onset to the cessation of the PCCC. [less ▲]

The biometric parameters (shoot density, length and width of leaves, leaf and epiphyte biomasses, leaf surface) of the P. oceanica meadow present a significant spatial variability at the mesoscale level (100 m2). All the parameters studied, excepting the number of leaves, decrease according to the depth. The horizontal spatial variations (centrifuge and centripetal distributions) reach a maximum in the shallower areas. The analysis of the microstructures (m2) of the meadow has not allowed a relationship to be established between the spatial variations of the biometric parameters and the environmental factors in the sediment (pH, water and organic matter content, red-ox potential, nutrient content). The heterogeneity of the meadow in the Revellata Bay quite probably results from the internal shoot and rhyzome growth dynamics. <br />On the other hand, it appears that the presence of the prairie modifies the physical-chemical characteristics of the sediment. In fact, the sandy patches present different physical-chemical characteristics: lower organic matter, different granulometric and much higher interstitial water nutrient levels, as well as a higher pH and oxydo-reduction potential.

Facultative paedomorphosis in salamanders refers to the presence of two ontogenetic pathways in natural populations – paedomorphosis, in which individuals retain gills at the adult stage, and metamorphosis, in which larvae metamorphose. The Mexican Cut Nature Preserve (Colorado, USA) is composed of numerous ponds which are inhabited by paedomorphic and metamorphic tiger salamanders. While paedomorphs usually stay in the same aquatic habitat all their life, metamorphs may leave water and colonize other ponds. The aim of this study was to determine the feeding habits of the two morphs from this metapopulation. To this end, adults were caught by dip-netting, stomach-flushed, measured and marked. Paedomorphs were only found in permanent waters. Metamorphs were present in all habitats, but particularly in the temporary ponds. Diet differed between ponds – reflecting their invertebrate composition – with a preponderance of either microcrustaceans, fairy shrimp or insect larvae. In ponds inhabited by the two morphs, paedomorphs consumed more prey items. Because dry mass and energy content varied between invertebrates, feeding on some of them, such as fairy shrimp in the temporary ponds where they are abundant, gave high energy intake to the predators. Because such resources are only available to the dispersive morph, metamorphs are at the advantage in being able to avoid competition with paedomorphs in permanent ponds and in using transient resources from the productive temporary waters.
