Begleitung schwer kranker und sterbender Kinder: Empfehlungen für die Praxis

Zusammenfassung: Der Tod eines Kindes ist bei uns ein seltenes, aber umso erschütternderes Ereignis. Die Begleitung sterbender Kinder ist nur mit Einbezug ihres sozialen Umfeldes möglich und erfordert entwicklungspsychologische Kenntnisse. Der Text fasst Aspekte der Entstehung des kindlichen Todeskonzeptes zusammen und beschreibt die psychischen Reaktionen schwer kranker Kinder und Jugendlicher. Abschließend geben die Autoren, ausgehend von ihren praktischen Erfahrungen, Empfehlungen und Orientierungshilfen für die Sterbebegleitun

A SspI PCR-RFLP detecting a silent allele at the goat CSN2 locus

The comparison between the cDNA sequence obtained and the published sequences of the goat CSN2 alleles showed a new single nucleotide polymorphism (SNP) (transition C-T) at the 180th nucleotide of the ninth exon. This mutation, which took place at 124 nt from the polyadenylation site, identifies a silent allele at the CSN2 locus named CSN2 A1. Since the 9th exon C-T transition creates a SspI endonuclease restriction site, the SspI digestion of a PCR product of 360 bp spanning the 9th exon and flanking regions, would allow carriers for the presence of thymine to be identified. The allelic frequency of the CSN2 A1 allele, determined in 170 goats belonging to an undefined genetic type reared in the province of Naples (Italy), was 0.23 It has been observed that the sequences in the 3’ untranslated regions (UTR), proximal to the polyadenylation site, can affect the mechanism of mRNA deadenylation and degradation. Therefore, it is reasonable to hypothesize that the C-T transition might, directly or indirectly, influence the stability of the mRNA and, consequently, the amount of protein produced

Characterization of two new alleles at the goat CSN1S2 locus.

Two novel alleles at the goat CSN1S2 locus have been identified: CSN1S2(F) and CSN1S2(D). Sequence analyses revealed that the CSN1S2(F) allele is characterized by a G --> A transition at the 13th nucleotide in exon 3 changing the seventh amino acid of the mature protein from Val to Ile. The CSN1S2(D) allele, apparently associated with a decreased synthesis of alpha s2-casein, is characterized by a 106-bp deletion, involving the last 11 bp of the exon 11 and the first 95 bp of the following intron. Methods (PCR-RFLP and PCR) for identification of carriers of these alleles have been developed

Measurements of the First RF Prototype of the SPIRAL2 Single Bunch Selector

WEPD062International audienceThe single bunch selector of the Spiral2 driver uses 100 ­ travelling wave electrodes driven by fast pulse generators. A 2.5 kV, 1 kW feed-through and a vacuum chamber housing the water cooled electrodes have been designed and built. The paper reviews the whole design and reports the results of first RF and power measurements

Slow chopper prototype for the SPIRAL 2PP project

A preliminary prototype of the slow chopper [1] for the Spiral 2 Preparatory Phase project [2] has been designed, developed and tested at INFN-LNS. The final version of the slow chopper will be placed along the beam line common to protons, deuterons and A/Q = 3 ions. This activity report shows the study, the hardware and the measurement results of the chopper prototype

Ferromagnetic models for cooperative behavior: Revisiting Universality in complex phenomena

Ferromagnetic models are harmonic oscillators in statistical mechanics. Beyond their original scope in tackling phase transition and symmetry breaking in theoretical physics, they are nowadays experiencing a renewal applicative interest as they capture the main features of disparate complex phenomena, whose quantitative investigation in the past were forbidden due to data lacking. After a streamlined introduction to these models, suitably embedded on random graphs, aim of the present paper is to show their importance in a plethora of widespread research fields, so to highlight the unifying framework reached by using statistical mechanics as a tool for their investigation. Specifically we will deal with examples stemmed from sociology, chemistry, cybernetics (electronics) and biology (immunology).Comment: Contributing to the proceedings of the Conference "Mathematical models and methods for Planet Heart", INdAM, Rome 201

Molecular cloning, promoter analysis and SNP identification of Italian Nicastrese and Saanen lactoferrin gene

Lactoferrin (Lf) is an iron-binding glycoprotein found in exocrine secretions including milk. High levels of lactoferrin may have a role in the prevention of microbial infection of the mammary gland. In this report we sequenced and characterized goat lactoferrin cDNA and its promoter region in two different breeds of goat. The complete cDNA comprised 2356 nucleotides, including 38bp at the 5'-UTR and 194bp at the 3'-UTR. The open reading frame is 2127bp long and it encodes a mature protein of 689 aminoacids. A total of 19 nucleotide differences, 11 of them being responsible for 8 aminoacid changes, were identified through the comparison with French, Korean and Tibetan goat lactoferrin cDNAs. About 1700bp of the lactoferrin gene promoter were sequenced. Sequence analysis revealed a non-canonical TATA box, multiple SP1/GC elements, and other putative binding sites for transcription factors, such as NF-kappaB, STAT3 and AP2. Two SNPs were identified, one of which would seem to create a new putative AP2 consensus sequence. The presence of an additional AP2 binding site could be associated with quantitative differences of such protein fraction, which could enhance all the activities related to such protein, and improve mammary gland defence against bacterial infections

Searching for galactic axions through magnetized media: QUAX status report

The current status of the QUAX R\&D program is presented. QUAX is a feasibility study for a detection of axion as dark matter based on the coupling to the electrons. The relevant signal is a magnetization change of a magnetic material placed inside a resonant microwave cavity and polarized with a static magnetic field.Comment: Contributed to the 13th Patras Workshop on Axions, WIMPs and WISPs, Thessaloniki, May 15 to 19, 201
