Measurement of polarization observables $$\textbf{T}$$, $${\textbf{P}}$$, and $${\textbf{H}}$$ in $$\mathbf {\pi ^0}$$ and $$\mathbf {\eta }$$ photoproduction off quasi-free nucleons

N. Jermann, B. Krusche, V. Metag, F. Afzal et autres

Abstract The target asymmetry T, recoil asymmetry P, and beam-target double polarization observable H were determined in exclusive $$\pi ^0$$ π 0 and $$\eta $$ η photoproduction off quasi-free protons and, for the first time, off quasi-free neutrons. The experiment was performed …

Differential Sequencing by Mass Spectrometry

Christian Jurinke, Christiane Honisch, Dirk van den Boom

The publication of the human genome sequence in 2001 and the completion of hundreds of thousands of virus, bacterial, archaeal, and eukaryotic genomes by 2020 affirm the success of worldwide genome sequencing projects. The availability of new reference sequence information of various …

Observation of the pη′ Cusp in the New Precise Beam Asymmetry Σ Data for γp→pη

F. Afzal, Y. Wunderlich, A. V. Anisovich, D. Bayadilov et autres

Data on the beam asymmetry $\mathrm{\ensuremath{\Sigma}}$ in the photoproduction of $\ensuremath{\eta}$ mesons off protons are reported for tagged photon energies from 1130 to 1790 MeV (mass range from $W=1748\text{ }\text{ }\mathrm{MeV}$ to $W=2045\text{ }\text{ }\mathrm{MeV}$). The data cover the full solid angle …

Microbial DNA Analysis by MALDI‐TOF Mass Spectrometry

Christiane Honisch, Vlad Serafim, Nicola Hennessy, David J. Allen et autres

Nucleic-acid-based matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS) applications for the detection and identification of viruses use specific or broad-range polymerase chain reaction (PCR) primers in combination with different post-PCR biochemistries. The most widely used biochemistry and variations thereof, a PCR/primer extension …

The World of Nucleic Acid Based Mass Spectrometry for Microbial and Viral Detection

Christiane Honisch

Recent years have seen a phenomenal increase in the use of MALDI-TOF mass spectrometry (MALDI-TOF MS) in microbiology laboratories.The introduction of this technology to microbiology has been a major success and MALDI-TOF MS is now used for routine diagnostic or diagnostic-like purposes …

P07.24 Predicted inclusivity and specificity of the cobas®4800 ct/ng test through global surveillance monitoring

S Cayabyab Hibbard, X Chen, J Osiecki, Christiane Honisch et autres

Introduction Nucleic acid amplification tests rely on conserved sequences for identification of specific targets, which may evolve, requiring global surveillance monitoring. An analysis of sequence heterogeneity within the primer and probe target region for the cobas® 4800 CT/NG Test was performed with …

P07.11 Whole genome sequencing characterisation of a unique neisseria strain generating a positive result with the cobas® ct/ng test

Christiane Honisch, S Cayabyab Hibbard, Rochak Mehta, Hang Phan et autres

Introduction Neisseria gonorrhoeae (NG) cause sexually transmitted bacterial infections. The Roche cobas® CT/NG Test is a qualitative Nucleic Acid Amplification test (NAAT) utilising a dual-target approach to detect sequences within the direct repeat (DR-9) region of the NG genome. To date, clinical …

A simple method to elute cell-free HIV from dried blood spots improves their usefulness for monitoring therapy

Xiaoning Wu, Megan Crask, Hector Medellín Ramírez, Trevor Landas et autres

BACKGROUND: Dried blood spots (DBS) improve access to HIV viral load (VL) testing, but yield increased VL measurements compared to the plasma reference method because of cell-associated viral nucleic acid. In clinical settings, DBS methods may falsely categorize many patients as failing …

Detection of Hepatitis C Virus Transmission by Use of DNA Mass Spectrometry

Lilia Ganova‐Raeva, Zoya Dimitrova, David S. Campo, Yu‐Lin Lin et autres

The molecular detection of transmission of rapidly mutating pathogens such as hepatitis C virus (HCV) is commonly achieved by assessing the genetic relatedness of strains among infected patients. We describe the development of a novel mass spectrometry (MS)-based approach to identify HCV …
