    Notes: Summary The ADP/ATP translocator is an abundant protein of the mitochondrial inner membrane, which in fungi and mammals is synthesized without a presequence. Here we report that the translocator from potato has an amino-terminal extension which may function in mitochondrial targeting. Several cDNA clones encoding the nucleotide sequence of the ADP/ATP translocator have been isolated from potato leaf and tuber cDNA libraries constructed in lambda phages. Only one class of cDNA clones was found but possibly different translocator genes are expressed in other tissues. High levels of transcripts for the translocator are found in all tissues analysed. Sequence determination of the complete insert of one of the clones reveals a long open reading frame of 1158 bp encoding a protein of 386 amino acids corresponding to a calculated molecular weight of 42 kDa. In contrast, the ADP/ATP translocator proteins from fungi and mammals are significantly smaller. Comparison of the Neurospora translocator with the potato protein shows about 75% sequence homology, being confined to the region after amino acid 85 of the potato polypeptide. Antibodies directed against the fungal translocator recognize a protein of 30 kDa in the inner membrane of potato mitochondria, suggesting that the mature protein has a similar size as the translocators from fungi and mammals. Thus, the additional segment of the potato ADP/ATP translocator forms an amino-terminal extension which may be involved in the import of the protein into plant mitochondria.

    Notes: Summary We have isolated the nad5 gene from the N-cytoplasm of Beta vulgaris, by heterologous hybridization with a nad5 probe from Chlamydomonas reinhardtii, and have determined the DNA sequence. The gene has a length of 3082 bp and consists of three exons and two introns, 459, 1269, 270, 848 and 357 bp in length, respectively. It has a similarity of 95.1% at the DNA level to the nad5 gene of Oenothera and the two respective proteins show an overall level of amino acid identity of 88.7%. Compared to Oenothera the reading frame of the first exon is extended in the 5′ direction and in the third exon there is a frameshift shortening the reading frame by 96 bp and changing the last 48 codons. The nad5 gene is a single copy gene in the N- and S-cytoplasm of Beta vulgaris and the organisation of the gene shows no apparent differences in the two cytoplasms. The gene is actively expressed; three major transcripts are detectable. The transcript patterns have been compared between the two cytoplasms and between different plant tissues.

    Description / Table of Contents: Zusammenfassung Die röntgenologische Funktionsuntersuchung der Halswirbelsäule (HWS) in Flexions- und Extensionsstellung wird zunehmend als Screeningverfahren zur Diagnostik segmentaler Funktionsstörungen eingesetzt. Ziel der vorliegenden Studie war, die Auswertmethode nach Penning zur metrischen Erfassung segmentaler Winkelgrade in der Sagittalebene auf Trennschärfe, Reliabilität und Anwendbarkeit zu überprüfen. Von 20 Patienten mit schmerzhafter Bewegungseinschränkung der HWS und von 20 beschwerdefreien Probanden wurden passiv gehaltene Röntgenfunktionsaufnahmen der HWS in Flexion und Extension angefertigt. Anhand dieser Röntgenbilder wurden die Winkelgrade der sagittalen segmentalen Beweglichkeit von 5 Ärzten im Blindverfahren ermittelt. Die statistische Auswertung erfolgte durch Vergleich der Mittelwerte im t-Test und durch Berechnung des Korrelationskoeffizienten r. Die Ergebnisse der Studie konnten zeigen, daß die von Penning vorgeschlagene Auswertmethode für die Segmente C 3/C 4 bis C 6/C 7 eine signifikante Unterscheidung zwischen Patienten und Probanden erlaubt (p K 0,05 und p K 0,01). Für die Übereinstimmung zwischen den 5 Untersuchern ergaben sich gute bis sehr gute Korrelationswerte (0,6 〈 r K 0,8 bzw. r 〉 0,8). Die ermittelten Meßwerte sind jedoch nur im Zusammenhang mit einer entsprechenden klinischen Symptomatik als „normal“ oder „funktionsgestört“ im Sinne einer segmentalen Hypo- bzw. Hypermobilität zu werten.
    Notes: Summary Functional radiographic analysis of the cervical spine in flexion and extension position is increasingly used as screening method for the diagnosis of segmental functional disorders. The objective of this study was to prove Penning's evaluation method for the metrical recording of segmental angles in the sagittal plane for selectivity, reliability and usability. Passive functional radiographs of the cervical spine in flexion and extension were taken of 20 patients with painful limitation of mobility of the cervical spine and 20 subjects, similar in sex and age, without complaints. The radiographs were duplicated. Five physicians measured the angles of segmental mobility in a blind study. Statistical analysis was conducted using the t-test and calculating the correlation coefficient “r”. The results of the study prove that the evaluation method by Penning shows a usable and, for segments C 3/C 4 to C 6/C 7, significant selectivity. The selectivity of p K 0.05 and p K 0.01 is sufficient to distinguish patients from healthy subjects. The correlation between the five reviewers showed good to very good results (0.6 〈 r K 0.8; r 〉 0.8). The measured values, however, have to be considered, in connection with the appropriate clinical symptoms, as still “normal” or “functionally disordered” in the context of segmental hypo- resp. hypermobility.

    Notes: Abstract We report on a 40-year-old woman with a 2-year history of iron-deficiency anemia of unknown origin. Repeated endoscopic investigations in the past had revealed no abnormality of the gastrointestinal system on macroscopic examination. Oral iron supplementation was shown to have no effect on serum iron levels and had no influence on the anemia. Upper gastrointestinal endoscopy performed at our hospital confirmed normal macroscopic findings. However, jejunal biopsies revealed subtotal villous atrophy of the mucosa of the small intestine. A strict gluten-free diet led to an increase in serum iron, resolution of the anemia, and restitution of normal mucosal architecture. Thus iron-deficiency anemia may be the lone manifestation of celiac disease.
