Zusammenfassung Klinisches/methodisches Problem Seit dem Auftreten des neuartigen Coronavirus Ende 2019 und der damit verbundenen Erkrankung – Coronavirus Disease 2019 (COVID-19) – kam es zum Ausrufen einer Pandemie durch die Weltgesundheitsorganisation (WHO). Der Referenzstandard für die Diagnose ist der Virusnachweis mittels „reverse transcription polymerase chain reaction“ (RT-PCR). Bei hoher Spezifizität ist die Sensitivität der RT-PCR jedoch stark abhängig von der Symptomdauer, der Viruslast, der Qualität der Probe sowie des verwendeten Tests. Radiologische Standardverfahren Im Rahmen von COVID-19 werden primär Thoraxröntgen und Thorax-Computertomographie(CT) zur Erkennung von Lungenmanifestationen bzw. deren Ausdehnung und von Komplikationen eingesetzt. Leistungsfähigkeit Die Sensitivität und Spezifizität des Thoraxröntgens bei COVID-19 ist gering. Die Thorax-CT weist eine hohe Sensitivität von ungefähr 90 % bei jedoch geringer Spezifizität auf (zwischen 25 und 33 %). Empfehlung für die Praxis Die Indikation für die Durchführung von Bildgebung im Rahmen von COVID-19 sollte immer mit Bedacht gestellt werden, um das Übertragungsrisiko für medizinisches Personal und andere Patienten zu minimieren. Die Bildgebung ist vor allem hilfreich zur Evaluierung des Ausmaßes der Lungenbeteiligung der Erkrankung, zur Abgrenzung von Komplikationen und Differenzialdiagnosen. Typischerweise zeigen sich bilaterale, subpleurale Milchglasverdichtungen mit oder ohne Konsolidierungsareale. Im Verlauf können auch Veränderungen einer organisierenden Pneumonie beobachtet werden. Bei Untersuchungen nach Genesung einer COVID-19-Pneumonie ist auf fibrotische Lungenveränderungen zu achten.

Oviduct Fluid

Hyaluronan (HA) has been related to fertilization and embryo development in the pig. Furthermore, HA is present in pig oviduct fluid and the lining epithelium, particularly of the pre-ovulatory sperm reservoir. Because the mechanisms that regulate HA synthesis have not yet been clarified, semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) was conducted to assess the expression of mRNAs of two HA-synthesizing enzymes (has2 and has3) in the oviduct epithelium (uterotubal junction, isthmus, ampullary–isthmic junction and ampulla segments) of non-inseminated (control) and inseminated (treatment) sows at pre-, peri- and post-ovulatory oestrus. Only has3 mRNA was detected; it was present in all tubal segments of both control and treatment samples. The level of has3 expression did not vary significantly between non-inseminated and inseminated specimens, but there was a tendency (NS) for increased mean values during the peri- and post-ovulatory stages compared with pre-ovulation. It is concluded that has3 is expressed by the porcine endosalpinx epithelium and the levels of expression do not vary during the critical periods of sperm transport and fertilization, despite fluctuating levels of HA in the tubal fluid at corresponding periods.

AIM: Aim was to detect Brain and Acute Leukemia, Cytoplasmic (BAALC) and ETS-related gene (ERG) expression in patients with acute myeloid leukemia (AML) as well as to study their biologic and prognostic impact on the disease outcome and survival.PATIENTS AND METHODS: The current study was carried out on 44 patients with denovo acute myeloid leukemia, as well as 44 age and sex matched controls. The quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) assay was performed for estimation of BAALC and ERG expression.RESULTS: The current study was carried out on 44 patients with denovo acute myeloid leukemia, as well as 44 age and sex matched controls. The quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) assay was performed for estimation of BAALC and ERG expression. BAALC was expressed in 36 (81.82%) of AML cases versus 10 (22.72%) of the control group which was highly statistically significant (P < 0.001). While ERG was positive in 39(88.64%) of cases and 8(18.18 %) of controls and that was also highly statistically significant (P < 0.001).CONCLUSION: Further researches still needed to clarify the role of BAALC and ERG in the pathogenesis of leukemia and their importance as targets for treatment of AML.

We report the first detection of Seoul hantavirus (SEOV) in a pet rat in Sweden. SEOV-specific antibodies were detected in the pet rat blood by focus reduction neutralising test (FRNT), and SEOV RNA in lung tissue was confirmed by reverse transcription-nested polymerase chain reaction (RT-PCR) followed by sequencing. The discovery follows the recent reports of SEOV infected pet rats, as well as associated human cases of severe haemorrhagic fever with renal syndrome (HFRS), in England and Wales.
