The biochemical composition and biophysical behaviour of pulmonary surfactant samples isolated from healthy Belgian White and Blue (BWB) and Holstein Friesian (HF) calves have been investigated and compared. Interesting differences in composition have been demonstrated. In particular, a higher level of total hydrophobic surfactant-associated proteins (SP) (due to higher levels of SP-B and SP-C) is reported in HF calves compared to BWB calves. Higher levels of phosphatidylcholine (PC) and especially the disaturated form of PC were also found in HF as compared to BWB calves. No immediate effect on the surface tension properties evaluated by the pulsating bubble surfactometer was found between the surfactant samples of the two breeds under physiological conditions. However, since a high content of disaturated PC and the presence of the SP-B and SP-C are thought to be essential for the surface activity, we propose that the reported modifications could contribute to the apparently lower resistance of the BWB calves to respiratory troubles in comparison with HF calves.

The steroid receptor coactivator SRC-1 modulates ligand-dependent transactivation of several nuclear receptors, including the receptors for sex steroid hormones. Reducing the expression of SRC-1 by injection of specific antisense oligonucleotides markedly inhibits the effects of estrogens of the sexual differentiation of brain and behavior in rats and inhibits the activation of female sexual behavior in adult female rats. SRC-1 thus appears to be involved in both the development and activation of sexual behavior. In the Japanese quail brain, we amplified by RT-PCR a 3,411-bp fragment extending from the HLH domain to the activating domain-2 of the protein. The quail SRC-1 is closely related to the mammalian (m) SRC-1 and contains a high proportion of GC nucleotides (62.5%). Its amino acid sequence presents 70% identity with mammalian SRC-1 and contains the three conserved LXXLL boxes involved in the interaction with nuclear receptors. In both males and females, RT-PCR demonstrates a similarly high level of expression in the telencephalon, diencephalon, optic lobes, brain stem, spinal cord, pituitary, liver, kidney, adrenal gland, heart, lung, gonads and gonoducts. Males express significantly higher levels of SRC-1 in the preoptic area-hypothalamus than females. In both sexes, lower levels of expression are observed in the cerebellum and muscles. In situ hybridization utilizing a mixture of four digoxigenin-labeled oligonucleotides confirms at the cellular level the widespread distribution of SRC-1 mRNA in the brain and a particularly dense expression in steroid-sensitive areas that play a key role in the control of male sexual behavior. These data confirm the presence and describe for the first time the SRC-1 distribution in the brain of an avian species. They confirm its broad, nearly ubiquitous, distribution in the entire body including the brain as could be expected for a coactivator that regulates to the action of many nuclear receptors. However this distribution is heterogeneous in the brain and sexually differentiated in at least some areas. The very dense expression of SRC-1 in limbic and mesencephalic nuclei that are associated with the control of male sexual behavior is consistent with the notion that this coactivator plays a significant role in the activation of this behavior.

Budgeting is not only a technical process but also a highly political one because technique and discretionary judgement are intertwined, and different actors have different interests. Budgetary procedures can and should help to reduce various types of information imbalance and help local authorities to deliver services more effectively. This study highlights certain sensitive areas in the budgeting process, analyses the solutions tried by the different Council of Europe member states and identifies practices that seem particulary worthwhile. It suggest finally conclusions and guidelines for central governments and for local and regional authorities. [less ▲]

Purification of a cytotoxic crude alkaloid extract of Cassytha filiformis led to the isolation of four known aporphine alkaloids: neolitsine, dicentrine, cassythine (= cassyfiline) and actinodaphnine. Their structures were determined by analysis of spectroscopic data. All isolated alkaloids were tested for their cytotoxic activities on cancer and non-cancer cell lines in vitro. Neolitsine was the most active against HeLa and 3T3 cells (IC 50 :21.6 microM, and 21.4 microM, respectively). Cassythine and actinodaphnine showed the highest activity against Mel-5 (IC 50 : 24.3 microM and 25.7 microM, respectively) and HL-60 (IC 50 : 19.9 microM and 15.4 microM, respectively). This is the first report on the cytotoxic activity of C. filiformis extract and of neolitsine and cassythine. Furthermore, the complete NMR data of cassythine and actinodaphnine are given here for the first time. [less ▲]

Vanadium has an antibacterial activity against Pseudomonas aeruginosa, especially under conditions of iron limitation. Some degree of resistance to V is inducible by prior exposure to the metal. One mutant (VS1) with a higher sensitivity to V was obtained by transposon mutagenesis of P. aeruginosa PA 59.20, a clinical isolate. This mutant had an insertion in a non-coding region, upstream of a cluster of four genes. Three of them show similarities to genes corresponding to known P. aeruginosa antibiotic efflux systems, including an efflux protein, a membrane fusion protein and an outer-membrane porin. This cluster was named mexGHI-opmD. By allelic exchange, three mutants, ncr (for non-coding region), mexI and opmD were constructed in P. aeruginosa PAO1. Next to V sensitivity, the ncr, mexI and opmD mutants also showed reduced production of elastase, rhamnolipids, pyocyanine, pyoverdine and had reduced swarming motility, phenotypes that are known to be regulated by quorum sensing. All wild-type phenotypes, including growth in the presence of V, were restored by complementation with the complete cluster. The production of N-acyl-homoserine lactones (AHLs) was detected using the Chromobacter violaceum bioassay. Total extracts from the three mutants failed to induce the production of violacein by C. violaceum, although AHLs were detected by TLC and C. violaceum overlay. Violacein production was restored by complementation with mexGHI-opmD. The opmD mutant grew very slowly in LB or CAA medium, indicating that OpmD has an important physiological function for the cell. In conclusion, it is believed that the MexGHI-OpmD pump is probably involved in AHL homeostasis in P. aeruginosa. [less ▲]
