The Utilization of the SaLux19-Based Loop-Mediated Isothermal Amplification (LAMP) Assay for the Rapid and Sensitive Identification of Minute Amounts of a Biological Specimen.

Our research has developed a highly sensitive and simple assay to detect small amounts of animal and human biological material in less than 40 min. The handheld SaLux19 device developed at the Max Planck Institute of Experimental Medicine in Göttingen, Germany, was used to validate our concept. The proposed system uses isothermal amplification of DNA in a rapid assay format.

Prevalence of SARS-COV-2 antibodies in the Thomayer University Hospital staff after the first wave of COVID-19.

Objectives: To map the prevalence of SARS-CoV-2 antibodies in the staff of the Thomayer University Hospital in Prague following the first wave of COVID-19. The main reason was the large number of COVID-19 patients admitted to the Thomayer University Hospital with confirmed SARS-CoV-2 infection.

Material And Methods: A volunteer study based on a questionnaire survey and determination of total antibodies (ECLIA, Roche) and individual classes of immunoglobulins (ELISA IgG and IgA, Euroimmun).

Influence of adjuvant chemotherapy on anti-Müllerian hormone in women below 35 years treated for early breast cancer.

The impact of chemotherapy on fertility appears to be of essential importance for the youngest cancer survivors. The aim of this study was to assess plasma anti-Mullërian hormone (AMH) evolution, using an automated sensitive AMH immunoassay in women younger than 35 years old before and after treatment with adjuvant chemotherapy for early breast cancer. We selected 54 women aged less than 35 years old, at the time of breast cancer diagnosis, who received chemotherapy between 2008 and 2014, and with plasma samples collected from the diagnosis, to 1 year, 3 years and 5 years post-diagnosis.

Natural killer-cell counts are associated with molecular relapse-free survival after imatinib discontinuation in chronic myeloid leukemia: the IMMUNOSTIM study.

Despite persistence of leukemic stem cells, patients with chronic myeloid leukemia who achieve and maintain deep molecular responses may successfully stop the tyrosine kinase inhibitor imatinib. However, questions remain unanswered regarding the biological basis of molecular relapse after imatinib cessation. In IMMUNOSTIM, we monitored 51 patients from the French Stop IMatinib trial for peripheral blood T cells and natural killer cells.

Underground Adaptation to a Hostile Environment: Acute Myeloid Leukemia vs. Natural Killer Cells.

Acute myeloid leukemia (AML) is a heterogeneous group of malignancies which incidence increases with age. The disease affects the differentiation of hematopoietic stem or precursor cells in the bone marrow and can be related to abnormal cytogenetic and/or specific mutational patterns. AML blasts can be sensitive to natural killer (NK) cell antitumor response.
