Abstract
The ribosomal S1 protein (rS1) is indispensable for translation initiation in Gram-negative bacteria. rS1 is a multidomain protein that acts as an RNA chaperone and ensures that mRNAs can bind the ribosome in a single-stranded conformation, which could be related to fast recognition. Although many ribosome structures were solved in recent years, a high-resolution structure of a two-domain mRNA-binding competent rS1 construct is not yet available. Here, we present the NMR solution structure of the minimal mRNA-binding fragment of Vibrio Vulnificus rS1 containing the domains D3 and D4. Both domains are homologues and adapt an oligonucleotide-binding fold (OB fold) motif. NMR titration experiments reveal that recognition of miscellaneous mRNAs occurs via a continuous interaction surface to one side of these structurally linked domains. Using a novel paramagnetic relaxation enhancement (PRE) approach and exploring different spin-labeling positions within RNA, we were able to track the location and determine the orientation of the RNA in the rS1-D34 bound form. Our investigations show that paramagnetically labeled RNAs, spiked into unmodified RNA, can be used as a molecular ruler to provide structural information on protein-RNA complexes. The dynamic interaction occurs on a defined binding groove spanning both domains with identical β2-β3-β5 interfaces. Evidently, the 3'-ends of the cis-acting RNAs are positioned in the direction of the N-terminus of the rS1 protein, thus towards the 30S binding site and adopt a conformation required for translation initiation.

Abstract
The highly infectious disease COVID-19 caused by the Betacoronavirus SARS-CoV-2 poses a severe threat to humanity and demands the redirection of scientific efforts and criteria to organized research projects. The international COVID19-NMR consortium seeks to provide such new approaches by gathering scientific expertise worldwide. In particular, making available viral proteins and RNAs will pave the way to understanding the SARS-CoV-2 molecular components in detail. The research in COVID19-NMR and the resources provided through the consortium are fully disclosed to accelerate access and exploitation. NMR investigations of the viral molecular components are designated to provide the essential basis for further work, including macromolecular interaction studies and high-throughput drug screening. Here, we present the extensive catalog of a holistic SARS-CoV-2 protein preparation approach based on the consortium's collective efforts. We provide protocols for the large-scale production of more than 80% of all SARS-CoV-2 proteins or essential parts of them. Several of the proteins were produced in more than one laboratory, demonstrating the high interoperability between NMR groups worldwide. For the majority of proteins, we can produce isotope-labeled samples of HSQC-grade. Together with several NMR chemical shift assignments made publicly available on covid19-nmr.com, we here provide highly valuable resources for the production of SARS-CoV-2 proteins in isotope-labeled form.

Abstract
The international Covid19-NMR consortium aims at the comprehensive spectroscopic characterization of SARS-CoV-2 RNA elements and proteins and will provide NMR chemical shift assignments of the molecular components of this virus. The SARS-CoV-2 genome encodes approximately 30 different proteins. Four of these proteins are involved in forming the viral envelope or in the packaging of the RNA genome and are therefore called structural proteins. The other proteins fulfill a variety of functions during the viral life cycle and comprise the so-called non-structural proteins (nsps). Here, we report the near-complete NMR resonance assignment for the backbone chemical shifts of the non-structural protein 10 (nsp10). Nsp10 is part of the viral replication-transcription complex (RTC). It aids in synthesizing and modifying the genomic and subgenomic RNAs. Via its interaction with nsp14, it ensures transcriptional fidelity of the RNA-dependent RNA polymerase, and through its stimulation of the methyltransferase activity of nsp16, it aids in synthesizing the RNA cap structures which protect the viral RNAs from being recognized by the innate immune system. Both of these functions can be potentially targeted by drugs. Our data will aid in performing additional NMR-based characterizations, and provide a basis for the identification of possible small molecule ligands interfering with nsp10 exerting its essential role in viral replication.

Abstract
The SARS-CoV-2 genome encodes for approximately 30 proteins. Within the international project COVID19-NMR, we distribute the spectroscopic analysis of the viral proteins and RNA. Here, we report NMR chemical shift assignments for the protein Nsp3b, a domain of Nsp3. The 217-kDa large Nsp3 protein contains multiple structurally independent, yet functionally related domains including the viral papain-like protease and Nsp3b, a macrodomain (MD). In general, the MDs of SARS-CoV and MERS-CoV were suggested to play a key role in viral replication by modulating the immune response of the host. The MDs are structurally conserved. They most likely remove ADP-ribose, a common posttranslational modification, from protein side chains. This de-ADP ribosylating function has potentially evolved to protect the virus from the anti-viral ADP-ribosylation catalyzed by poly-ADP-ribose polymerases (PARPs), which in turn are triggered by pathogen-associated sensing of the host immune system. This renders the SARS-CoV-2 Nsp3b a highly relevant drug target in the viral replication process. We here report the near-complete NMR backbone resonance assignment (1H, 13C, 15N) of the putative Nsp3b MD in its apo form and in complex with ADP-ribose. Furthermore, we derive the secondary structure of Nsp3b in solution. In addition, 15N-relaxation data suggest an ordered, rigid core of the MD structure. These data will provide a basis for NMR investigations targeted at obtaining small-molecule inhibitors interfering with the catalytic activity of Nsp3b.

Abstract
We report here the nuclear magnetic resonance 19F screening of 14 RNA targets with different secondary and tertiary structure to systematically assess the druggability of RNAs. Our RNA targets include representative bacterial riboswitches that naturally bind with nanomolar affinity and high specificity to cellular metabolites of low molecular weight. Based on counter‐screens against five DNAs and five proteins, we can show that RNA can be specifically targeted. To demonstrate the quality of the initial fragment library that has been designed for easy follow‐up chemistry, we further show how to increase binding affinity from an initial fragment hit by chemistry that links the identified fragment to the intercalator acridine. Thus, we achieve low‐micromolar binding affinity without losing binding specificity between two different terminator structures.

Abstract
Initiation of bacterial translation requires that the ribosome-binding site in mRNAs adopts single-stranded conformations. In Gram-negative bacteria the ribosomal protein S1 (rS1) is a key player in resolving of structured elements in mRNAs. However, the exact mechanism of how rS1 unfolds persistent secondary structures in the translation initiation region (TIR) is still unknown. Here, we show by NMR spectroscopy that Vibrio vulnificus rS1 displays a unique architecture of its mRNA-binding domains, where domains D3 and D4 provide the mRNA-binding platform and cover the nucleotide binding length of the full-length rS1. D5 significantly increases rS1’s chaperone activity, although it displays structural heterogeneity both in isolation and in presence of the other domains, albeit to varying degrees. The heterogeneity is induced by the switch between the two equilibrium conformations and is triggered by an order-to-order transition of two mutually exclusive secondary structures (β-strand-to-α-helix) of the ‘AERERI’ sequence. The conformational switching is exploited for melting of structured 5′-UTR’s, as the conformational heterogeneity of D5 can compensate the entropic penalty of complex formation. Our data thus provides a detailed understanding of the intricate coupling of protein and RNA folding dynamics enabling translation initiation of structured mRNAs.

Abstract
Paramagnetic relaxation enhancement (PRE) is a versatile tool for NMR spectroscopic structural and kinetic studies in biological macromolecules. Here, we compare the quality of PRE data derived from two spin labels with markedly different dynamic properties for large RNAs using the I-A riboswitch aptamer domain (78 nt) from Mesoplamsa florum as model system. We designed two I-A aptamer constructs that were spin-labeled by noncovalent hybridization of short spin-labeled oligomer fragments. As an example of a flexible spin label, UreidoU-TEMPO was incorporated into the 3' terminal end of helix P1 while, the recently developed rigid spin-label Çm was incorporated in the 5' terminal end of helix P1. We determined PRE rates obtained from aromatic 13C bound proton intensities and compared these rates to PREs derived from imino proton intensities in this sizeable RNA (~78 nt). PRE restraints derived from both imino and aromatic protons yielded similar data quality, and hence can both be reliably used for PRE determination. For NMR, the data quality derived from the rigid spin label Çm is slightly better than the data quality for the flexible UreidoTEMPO as judged by comparison of the structural agreement with the I-A aptamer crystal structure (3SKI).

Abstract
Ward rounds have been regarded as a traditional forum for the teaching and training of trainees. The aim of this research project was to look at what role ward rounds play in the medical education of trainees in obstetrics and gynaecology. A questionnaire comprising 10 statements devised around the theme of quality of medical education and the overall experience of ward rounds was distributed at the Specialist Registrars monthly training days. A total of 46 completed questionnaires were received. The ward rounds took place at least twice weekly at the Welsh Deanery hospitals, however, none of the trainees regarded these ward rounds as 'teaching' ward rounds. A total of 32 (70%) of the trainees disagreed or were uncertain that they learnt something new on ward rounds each day and 34 (74%) of trainees agreed or strongly agreed that in the presence of a consultant, SpRs are not given a chance to lead a ward round. The educational role of the ward rounds does not seem fully utilised in the Welsh Deanery Hospitals and needs to be developed further to suit the needs of junior doctors.

Abstract
OBJECTIVE To determine whether administration of exogenous human chorionic gonadotrophin (hCG) treatment improve the pregnancy outcome in first trimester threatened miscarriages. DESIGN A prospective, double blind, randomised, placebo-controlled trial. SETTING The Early Pregnancy Assessment Unit, Royal Bolton Hospital, Bolton, United Kingdom. POPULATION One hundred and eighty-three women with vaginal bleeding and a viable fetus seen on ultrasound scan (USS) in the first 12 weeks of pregnancy. METHODS The patients were randomised to receive either hCG or placebo treatment until 14 weeks of gestation. MAIN OUTCOME MEASURES The primary objective of the trial was to determine the miscarriage rate in the hCG arm compared from the placebo arm. RESULTS Of the 183 cases, 87 were randomised to treatment with hCG while 96 were randomised to receive a placebo. Forty-seven (25%) did not comply with the study protocol. The mean [SD] gestational age at presentation was 7 [1.33] weeks. The mean [SD] age of women in study was 27 [5] years in the placebo and 28 [5] in the hCG group. The mean body mass index (kg/m(2)) was 25 [5] in the study. The number of patients actively bleeding per vaginum at presentation was 85 (93%) in placebo group and 79 (96%) in the hCG group. The median number of hCG or placebo injections for both groups was 7. Ten women (11%) in the placebo group proceeded to have a complete miscarriage, as did 10 women (12%) in the hCG group, relative risk (RR) [95% confidence interval (CI)] of 1.1 (0.63-1.6). CONCLUSION Our study showed no evidence of a difference in the outcome of threatened miscarriages when treated with hCG in the first trimester, this may be because our study sample size was small and follow up was suboptimal. A large, randomised, multicentre trial is still needed to establish the usefulness of hCG treatment in cases of threatened miscarriage.

Abstract
Transport in vitro fertilisation (IVF) is an important development in assisted conception. We report our experience of transport IVF treatment from May 1993 to April 1996 at Arrowe Park Fertility Centre. A total of 74 patients were treated during this period. The main indications of treatment were tubal damage, unexplained infertility of more than 3 years duration, polycystic ovarian disease and endometriosis. Total number of simulated ovarian cycles were 101. Thirteen cycles were abandoned. Eighty-eight transport IVF cycles led to 29 pregnancies, giving a live birth rate and on-going pregnancy rate per patient of 31% and per cycle rate of 23%. There was one case of severe ovarian hyperstimulation syndrome. Of the 74 patients, 70 (95%) patients preferred to have treatment at the local hospital. Transport IVF is an effective, efficient and economic way of providing assisted conception at district general hospital. The success rate and safety of transport IVF are comparable with conventional IVF treatment.
