    Abstract Neben den häufiger auftretenden Frühformen von Infektionen mit ß-hämolysierenden Streptokokken in der Neu- und Frühgeborenenperiode finden sich seltener auch Fälle von späten Infektionen mit Auftreten nach der ersten Lebenswoche. Der Infektions- bzw. Übertragungsweg dieser späten Infektion ist letztendlich nicht geklärt. Diskutiert werden eine verzögerte Manifestation, Reinfektionen wie auch horizontale, nosokomiale Infektionen. Einzelfallberichte zu einem weiteren Infektionsweg über infizierte Muttermilch stillender Mütter sind berichtet worden. Hypothesen gehen hier von entweder einer primären Besiedlung der oropharyngealen Mukosa von B-Streptokkoken durch vertikale Infektion unter der Geburt aus. Durch das Stillen wird eine Übertragung in die Milchgänge durch Unterdruck am Ende der Stillmahlzeit ermöglicht. Eine erneute Infektion des Neugeborenen nach Vermehrung der Keime in der Muttermilch kann dann zu dieser schwer verlaufenden Sepsis führen. Eine weitere Hypothese beinhaltet die Besiedlung der Muttermilch einer im Vaginalabstrich B-Streptokokken positiven Mutter über die Hände. Wir berichten von zwei Kasuistiken bei denen eine B-Streptokokkensepsis und –Meningitis über infizierte Muttermilch aufgetreten war. Die erste Kasuistik beschreibt ein reifes Neugeborenes mit unauffälliger Schwangerschaftsanamnese und guter postnataler Adaptation, welches nach Entlassung aus der Klinik nach der U2 am siebzehnten Lebenstag mit schwerer Sepsis und Meningitis vorgestellt wurde. In der Blutkultur und im Liquor konnten ß-hämolysierende Streptokokken nachgewiesen werden. In der Muttermilch ließen sich entsprechende Keime nachweisen. Aufgrund rezidivierender Krampfanfälle und tiefer Apnoen wurde die Intubation und Beatmung notwendig. Trotz unverzüglich begonnener antibiotischer Dreifachtherapie kam es im Verlauf zu schweren Folgeerscheinungen mit großen cerebralen Infarzierungen bifrontal und okkzipital. Die zweite Kasuistik berichtet von einem reifen Neugeborenen, unauffälliger Schwangerschaftsanamnese mit negativen mütterlichen Abstrichen bezüglich ß-hämolysierender Streptokokken und unauffälliger postnataler Adaptation. Am zwölften Lebenstag wurde das Neugeborenen mit schlechtem Trinkverhalten, Hyperexzitabilität und Berührungsempfindlichkeit vorgestellt. Bei deutlicher Nackensteifigkeit bestand der Verdacht auf eine Meningitis. In der Blutkultur und Magensekret konnten ß-hämolysierende Streptokokken nachgewiesen werden. Gleichermaßen zeigte sich eine hohe Keimzahl der Erreger in der Muttermilch. Bei late onset Infektionen eines gestillten Neugeborenen sollte neben rezidivierenden Infektionen auch an eine Übertragung durch infizierte Muttermilch gedacht werden und bei Verdacht eine sofortige Beendigung der Muttermilchzufuhr zur Folge haben. Interessanterweise sind einige Fälle infizierter Muttermilch ohne klinische Hinweise auf eine Mastitis beschrieben.

    Abstract Memory B cells (MBCs) and plasma cells (PCs) constitute the two cellular outputs of germinal center (GC) responses that together facilitate long-term humoral immunity. Although expression of the transcription factor BLIMP-1 identifies cells undergoing PC differentiation, no such marker exists for cells committed to the MBC lineage. Here, we report that the chemokine receptor CCR6 uniquely marks MBC precursors in both mouse and human GCs. CCR6

    Abstract A term female infant developed late onset group B streptococcal disease on Day 12 of life. The source of the organism appeared to be expressed maternal breast milk in the absence of clinical mastitis. Asymptomatic excretion of group B Streptococcus in breast milk may be an underrecognized cause of neonatal infection.

    Abstract The title compound is obtained via the intramolecular condensation of 3-(2-oxo-1,2-diphenylethyl)quinoxalin-2(1H)-one in the presence of excessive boron trifluoride etherate and characterized by ¹HNMR, ¹³CNMR, IR, and EI-MS. The solution-based and solid-state fluorescence along with the electrochemical property are studied in detail. The unique herring-bone arrangement which is revealed by the X-ray crystallography should account for the intense solid-state fluorescence. The theoretic calculations are employed to clarify the origin of the large Stokes shift and the positive solvatochromism in view of the geometric relaxation and the transition feature.

    Abstract Objective: This study assessed the outcome of shaping the mesial roots of mandibular first molars containing band-shaped isthmuses with an isthmus floor located at the apical third with Reciproc Blue and Rotate instruments in terms of canal transportation, canal aberrations and unprepared apical canals.
    Materials and methods: Pair-matched mesial roots of mandibular first molars according to their isthmus location (distance from apical foramina) and size were constructed based on quantitative measurements (length, major and minor diameter at isthmus roof and floor) on preoperative micro-CT scanning (n = 10). The pair-matched specimens were prepared either using Reciproc Blue R25 (25.08v) or Rotate (15.04, 20.05, 25.06) instruments and then subjected to a second micro-CT scanning. Micro-CT scans were analysed to evaluate the canal transportation at the apical foramen and isthmus floor levels and the frequency of procedural errors (separated instruments, artificial canal preparation, cross shaping and unprepared apical canals). Canal transportation values were compared using Mann-Whitney U, and the distribution of procedural errors was compared with chi-square tests with a 5% significance threshold.
    Results: Greater transportation values were detected in the apical foramen level compared to the isthmus floor in both groups. No significant difference was detected between Rotate and Reciproc Blue groups in terms of absolute transportation values and the incidence of procedural errors (p > .05).
    Conclusion: Preparation of mesial root canals containing a band-shaped isthmus at the apical portion with Reciproc Blue and Rotate instruments caused transportation of the original canal position at the isthmus floor and the apical foramen levels and resulted in procedural errors.
    Clinical relevance: This ex vivo micro-CT study using controlled pair-matched specimens showed that presence of a band-shaped isthmus complicates canal preparation procedure irrespective of the preparation systems.

    Abstract Intercalated motifs or i-Motifs (iMs) are nucleic acid structures formed by cytosine-rich sequences, which may regulate cellular processes and have broad applications in nanotechnology due to their pH-dependent nature. We have developed an iM-specific nanobody (iMbody) that can recognize iM DNA structures regardless of their sequences, making it a versatile research tool for studying iMs in various contexts. Here, we provide a protocol for the bacterial expression and His-tag purification of iMbody. We then describe procedures for performing ELISA and immunostaining using iMbody.

    Abstract The medial olivocochlear (MOC) efferent system modifies cochlear output to aid signal detection in noise, but the precise role of efferents in speech-in-noise understanding remains unclear. The current study examined the contribution of the MOC reflex for speech recognition in noise in 30 normal-hearing young adults (27 females, mean age = 22.7 yr). The MOC reflex was assessed using contralateral inhibition of transient-evoked otoacoustic emissions. Speech-in-noise perception was evaluated using the coordinate response measure presented in ipsilateral speech-shaped noise at signal-to-noise ratios (SNRs) ranging from -12 to 0 dB. Performance was assessed without and with the presence of contralateral noise to activate the MOC reflex. Performance was significantly better with contralateral noise only at the lowest SNR. There was a trend of better performance with increasing contralateral inhibition at the lowest SNR. Threshold of the psychometric function was significantly correlated with contralateral inhibition. Response time on the speech task was not significantly correlated with contralateral inhibition. Results suggest that the MOC reflex contributes to listening in low SNRs and the relationship between the MOC reflex and perception is highly dependent upon the task characteristics.

    Abstract Background: The assessment of personality functioning is at the core of current dimensional models of personality disorders. A variety of measures from different clinical and research traditions aim to assess basic psychological capacities regarding the self and others. While some instruments have shown reliability and validity in clinical or other selected samples, much less is known about their performance in the general population.
    Methods: In three samples representative of the German adult population with a total of 7,256 participants, levels of personality functioning were measured with the short 12-item version of the Operationalized Psychodynamic Diagnosis - Structure Questionnaire (OPD-SQS). We addressed questions of factor structure, reliability, validity, factorial invariance, and provide norm values.
    Results: Confirmatory factor analysis indicated a satisfactory to good model fit. OPD-SQS models were mostly unaffected by variables such as gender, age, or measurement time. As expected, personality functioning was associated with general psychopathology as well as indices of occupational functioning.
    Conclusion: The OPD-SQS is a viable measure to assess personality functioning in the general population.
