Notizen: Critical currents of YBa2Cu3O7−δ bulk-sintered samples were measured at and above 77 K in the presence of magnetic fields. In moderate magnetic fields a H−n dependence with n〈1 was observed. Transport measurements give n(approximately-equal-to)0.5, indicating that critical currents are limited by flux creep rather than by field quenching of Josephson junctions.

Notizen: A setup for pulse radiolysis experiments is described consisting of the following main components: an array of 15 photomultipliers attached to a spectrograph (allowing 4032 spectra to be recorded with a time resolution of 500 ns per spectrum), self-regulating high-voltage supply for the photomultipliers, computer-controlled solution mixing and dispensing system, and provisions for continuous dose variation of the FEBETRON-accelerator electron beam. The general performance of the system is discussed and construction or electronic details are given for special components.

Beschreibung: Background: Medium-chain acyl-CoA dehydrogenase (MCAD) deficiency is the most common disorder of mitochondrial fatty acid β-oxidation and a target disease of newborn screening in many countries.Case presentationWe report on two siblings with mild MCAD deficiency associated with a novel splice site mutation in the ACADM gene. The younger sibling was detected by newborn screening, while the older sister was missed, but diagnosed later on by genetic family testing. Both children were found to be compound heterozygous for the common c.985A 〉 G (p.K329E) mutation and a novel splice site mutation, c.600-18G 〉 A, in the ACADM gene. To determine the biological consequence of the c.600-18G 〉 A mutation putative missplicing was investigated at RNA level in granulocytes and monocytes of one of the patients. The splice site mutation was shown to lead to partial missplicing of the ACADM pre-mRNA. Of three detected transcripts two result in truncated, non-functional MCAD proteins as reflected by the reduced octanoyl-CoA oxidation rate in both patients. In one patient a decrease of the octanoyl-CoA oxidation rate was found during a febrile infection indicating that missplicing may be temperature-sensitive. Conclusions: Our data indicate that the c.600-18G 〉 A variant activates a cryptic splice site, which competes with the natural splice site. Due to only partial missplicing sufficient functional MCAD protein remains to result in mild MCADD that may be missed by newborn screening.

Beschreibung: Background: Acute Otitis Media (AOM) is an important and common disease of childhood. Bacteria isolated from cases of clinically problematic AOM in German children were identified and characterized Methods: In a prospective non-interventional study in German children between 3 months and less than 60 months of age with Ear, Nose and Throat Specialist --confirmed AOM, middle ear fluid was obtained by tympanocentesis (when clinically indicated) or by careful sampling of otorrhea through/at an existing perforation. Results: In 100 children with severe AOM, Haemophilus influenzae was identified in 21% (18/21, 85.7% were non-typeable [NTHi]), Streptococcus pneumoniae in 10%, S. pyogenes in 13% and Moraxella catarrhalis in 1%. H. influenzae was the most frequently identified pathogen in children from 12 months of age. H. influenzae and S. pneumoniae were equally prevalent in children aged 3--11 months, but S. pyogenes was most frequently isolated in this age group. NTHi AOM disease appeared prevalent in all ages. Conclusions: NTHi, S. pneumoniae and S. pyogenes are implicated as important causes of complicated AOM in children in Germany. NTHi disease appears prevalent in all ages. The impact of vaccination to prevent NTHi and S. pneumoniae AOM may be substantial in this population and is worth investigating.
