RESUMEN

Objective: Evaluation of a project offering low-threshold anonymous counseling services jointly by mental health services and child and youth services to support children in families with mentally ill parents Methods: Evaluating performance data and completed questionnaires returned by parents included in the project. Results: Between 2011-2014, 150 families received up to 10 sessions of family-oriented counseling. The survey results indicate a high level of satisfaction with the services of the cooperation project. The vast majority of respondents said that they would recommend this service to others or would themselves take advantage of the services again. Conclusion: A collaboration of service providers from psychiatry and child and youth welfare department resulting in continuous availability of counseling with a common family medical perspective represents a forward-looking model for families with a mentally ill parent.

RESUMEN

Array technology is a widely used tool for gene expression profiling in various biological systems. However, the application of this method to mammalian preimplantation embryos is limited by the small amount of mRNA that can be extracted from a single embryo, which is not sufficient for array analysis. Here we report a protocolfor the rapid global amplification of embryonic mRNA that permits the generation of expression profiles from single murine blastocysts. The approach combines global PCR and 77 RNA polymerase amplification and allows the preparation of labeled, amplified RNA for array hybridization from single murine blastocysts containing approximately 1.5 pg mRNA in less than 12 h. We demonstrate that this amplification procedure is highly reproducible and does not bias original relative mRNA levels. Signal patterns from various embryonic stages of murine development revealed marked differences in mRNA expression that were in accordance with previously published data. We found genes known to be involved in embryonic apoptosis expressed at different levels in individual murine day 3.5 blastocysts. This technique can thus be used to assess embryonic viability and investigate molecular mechanisms of embryonic development.

RESUMEN

The skin secretions of female and male Litoria splendida have been monitored monthly over a three-year period using HPLC and electrospray mass spectrometry. Two minor peptides are present only in the skin secretion of the male. The first of these is the female-attracting aquatic male sex pheromone that we have named splendipherin, a 25 amino acid peptide (GLVSSIGKALGGLLADVVKSKGQPA-OH). This pheromone constitutes about 1% of the total skin peptides during the breeding season (January to March), dropping to about 0.1% during the period June to November. Splendipherin attracts the female in water at a concentration of 10-11-10-9 M, and is species specific. The second peptide is a wide-spectrum antibiotic of the caerin 1 group, a 25 residue peptide (GLLSVLGSVAKHVLPHVVPVIAEKL-NH2) named caerin 1.10. The neuropeptides of L. splendida are also seasonally variable, the change identical for both the female and male. During the period October to March, the sole neuropeptide present in skin secretions is caerulein [pEQDY(SO3)TGWMDF-NH2]; this is active on smooth muscle and is also an analgaesic. During the southern winter (June to September), more than half of the caerulein is hydrolysed to [pEQDYTGWMDF-NH2], a peptide that shows no smooth muscle activity. In place of caerulein, a new peptide, Phe8 caerulein [pEQDY(SO3)TGWFDF-NH2], becomes a major component of the skin secretion. Perhaps this seasonal change is involved in thermoregulation, that is, with the initiation and maintenance of the inactive (hibernation) phase of the animal.

RESUMEN

Sixteen caerulein-type peptides have been isolated from the skin secretions of the Australian Blue Mountains tree frog Litoria citropa. There are four groups of these peptides. The first is based on the structure of the known neuropeptide caerulein [pEQDY(SO(3))TGWMDF-NH(2)], now renamed caerulein 1.1. Examples of peptides of the other groups are as follows: caerulein 2.1 [pEQDY(SO(3))TGAHMDF-NH(2)], caerulein 3.1 [pEQDY(SO(3))GTGWMDF-NH(2)] and caerulein 4.1 [pEQDY(SO(3))TGSHMDF-NH(2)]. All of these peptides are accompanied by the associated peptide where Phe replaces Met, and all eight of the caerulein peptides are accompanied by the desulfated analogues. Negative ion electrospray mass spectrometry (ES-MS) is used to determine the molecular weights of the caeruleins 1-4 [from their [M - H](-) ions], while the sequences of the peptides are determined from the B and Y + 2 cleavage ions in the mass spectra of the [MH(+) - SO(3)](+) ions.

RESUMEN

Nineteen citropin peptides are present in the secretion from the granular dorsal glands of the Blue Mountains tree-frog Litoria citropa; 15 of these peptides are also present in the secretion from the submental gland. Two major peptides, citropin 1.1 (GLFDVIKKVASVIGGL-NH2), citropin 1.2 (GLFDIIKKVASVVGGL-NH2) and a minor peptide, citropin 1.3 (GLFDIIKKVASVIGGL-NH2) are wide-spectrum antibacterial peptides. The amphibian has an endoprotease which deactivates these membrane-active peptides by removing residues from the N-terminal end: loss of three residues gives the most abundant degradation products. The solution structure of the basic peptide citropin 1.1 has been determined by NMR spectroscopy [in a solvent mixture of trifluoroethanol/water (1 : 1)] to be an amphipathic alpha-helix with well-defined hydrophobic and hydrophilic regions. The additional four peptides produced by the dorsal glands are structurally related to the antibacterial citropin 1 peptides but contain three more residues at their C-terminus [e.g. citropin 1.1.3 (GLFDVIKKVASVIGLASP-OH)]. These peptides show minimal antibacterial activity; their role in the amphibian skin is not known.

RESUMEN

Tadpoles of the Magnificent Tree Frog Litoria splendida produce host defence peptides early in their development and well before metamorphosis. Peptides were identified and characterized using high performance liquid chromatography and electrospray mass spectrometry. No host defence peptides were identified in the eggs. The neuropeptide caerulein was detected 10 d after egg deposition, and the antibiotic peptides caerin 1.1, caerin 1.6 and caerin 3.1 first appeared at 14 d. The concentration of peptides increases with the onset of metamorphosis at 84 d, when the host-defence peptide profile is the same as that of the adult.

RESUMEN

The glandular secretions of the skin of Litoria rubella specimens collected from five locations on the eastern seaboard of Queensland (Australia) contain the three tryptophyllin peptides Phe Pro Trp Leu (NH2), Phe Pro Trp Pro (NH2) and Phe Pro Phe Pro Trp Leu (NH2). The relative proportions of these peptides in the glandular secretion are associated with geographic location, i.e. Phe Pro Trp Pro (NH2) is a minor component of the peptide mixture in frogs from southern Queensland, but becomes significantly more abundant as the location becomes more northerly. This trend indicates an evolutionary change in the animal, but for what reason, and over what timescale is not known at this time.
