catena-Poly[[[cis-aquadibromidocobalt(II)]-μ-(pyrazine-2-carboxylic acid)-κ3 N 1,O:N 4] monohydrate]
The title compound, {[CoBr2(C5H4N2O2)(H2O)]·H2O}n, is a one-dimensional coordination polymer which crystallizes as a monohydrate. The asymmetric unit contains one CoII atom in a distorted octahedral geometry, forming a chain parallel to [010] with the pyrazine carboxylic acid ligands coordinating on one side in a bidentate fashion through one N and one O atom, and in a monodentate fashion through a N atom, with N atoms trans, and with both ligands lying in the same plane. The bromide atoms are cis to each other, while a water molecule occupies the final octahedral coordination site. The chains are linked together though an O—H⋯Br hydrogen bonding network, and are further stabilized by an O—H⋯Br and O—H⋯O hydrogen-bonding framework with the solvent water molecule
Experiences of intensive home treatment for a mental health crisis during the perinatal period: A UK qualitative study
Some women with severe perinatal mental health difficulties in England are cared for by acute home treatment services, known as Crisis Resolution Teams (CRTs), which provide short-term home-based treatment for adults experiencing a mental health crisis. Intensive home treatment has been trialed in a number of countries, but it is not known how well suited it is to the needs of perinatal women. This qualitative study aimed to explore how women and practitioners experience the provision of intensive home treatment for perinatal mental health problems. Semi-structured interviews were conducted with women who had received intensive home treatment in the perinatal period (n = 15), and focus groups were held with practitioners working in CRTs or in specialist perinatal mental health services (3 groups, n = 25). Data were analysed thematically. Women commonly found intensive home treatment problematic, experiencing it as intrusive and heavily risk-focused, with poor staff continuity and little tailoring to the perinatal context. However, women valued emotional support when provided, particularly when it had a perinatal focus, sometimes based on practitioners sharing their own experiences. Some women also appreciated avoiding hospital admission, but choice was often limited. Practitioners reported a lack of perinatal training among CRT staff and described difficulties tailoring treatment to perinatal women's needs. Currently, intensive home treatment, as offered by CRTs, may not be well suited to women with perinatal mental health difficulties. Findings suggest a need to develop community crisis responses that are better tailored to the needs of this population
Part II Farmers’ Experiences of the Farm Assessment: Interviews with Farmers
The objective of work package 463 was to test the implementation of the WQ assessment Scheme on regular broiler farms. We assessed the perception and attitudes of farmers towards animal welfare and on-farm assessment, the experience and evaluation of the assessment itself and the relevance and applicability of the results. at the same time animal scientists assessed the welfare of the animals by WQ monitoring instruments. In addition they scored foot pad lesions at the slaughterhouse by way of video imaging. Both studies proceeded in parallel; farmers told, hence, about their real-life experience. It is to be noted that the WQ monitoring instruments were not at their final state, and experiences and comments of the farmers are to be interpreted as reflection and discussion on work in progress.
A team of sociologists carried out the study on farmers’ experiences, perception and attitude whereas the assessment of animal welfare was done by animal scientists. the study took place in three countries – Netherlands, Italy and the UK.
We choose to focus on broilers for two main reasons. First of all the production cycle of broilers is relatively short and so it is possible to assess the welfare of different flocks within a short time-span and to check more easily any improvement of animal welfare as a result of farmers’ interventions. a second reason for focusing on broilers is that it allows us to link this project to another project where a new way of checking for foot-pad lesions is developed. this is, moreover, a relatively easy manner of checking animal welfare that allows us to lower the burden of three on-farm assessments considerably.
In the following we report on the results of the welfare assessment (Part I) and the interviews with farmers about their perception and experience of animal welfare and the welfare assessment (Part II). In both parts we compare the results across the participating countries (Netherlands, Italy and United Kingdom). More in detail information on the national results of welfare assessment and interviews with farmers can be found in the deliverables 4.31.a (farmers’ interviews) and D4.31b (assessment results). as appendixes, we provide the technical and sociological questionnaires and the assessment reports that were sent to the farmers in the different countries.

Analyzing the vast coronavirus literature with CoronaCentral
he SARS-CoV-2 pandemic has caused a surge in research exploring all aspects of the virus and its effects on human health. The overwhelming publication rate means that researchers are unable to keep abreast of the literature. To ameliorate this, we present the CoronaCentral resource that uses machine learning to process the research literature on SARS-CoV-2 together with SARS-CoV and MERS-CoV. We categorize the literature into useful topics and article types and enable analysis of the contents, pace, and emphasis of research during the crisis with integration of Altmetric data. These topics include therapeutics, disease forecasting, as well as growing areas such as “long COVID” and studies of inequality. This resource, available at https://coronacentral.ai, is updated daily

Successful use of axonal transport for drug delivery by synthetic molecular vehicles
We report the use of axonal transport to achieve intraneural drug delivery. We constructed a novel tripartite complex of an axonal transport facilitator conjugated to a linker molecule bearing up to a hundred reversibly attached drug molecules. The complex efficiently enters nerve terminals after intramuscular or intradermal administration and travels within axonal processes to neuron cell bodies. The tripartite agent provided 100-fold amplification of saturable neural uptake events, delivering multiple drug molecules per complex. _In vivo_, analgesic drug delivery to systemic and to non-targeted neural tissues was greatly reduced compared to existing routes of administration, thus exemplifying the possibility of specific nerve root targeting and effectively increasing the potency of the candidate drug gabapentin 300-fold relative to oral administration
4,4′-Dichloro-N,N′-(o-phenylene)dibenzenesulfonamide
The title compound, C18H14Cl2N2O4S2, is a diamine that is a precursor to a quinonoid bidentate redox-active ligand. The dihedral angles between the central phenyl ring and the end rings are 87.5(1) and 60.7(1)°, while the two end rings make a dihedral angle of 82.5(1)°. The crystal structure is stabilized by two weak intermolecular N—H⋯O hydrogen bonds, as well as one intramolecular C—H⋯O and one N—H⋯N hydrogen bond
A method to estimate the efficiency of gene expression from an integrated retroviral vector
BACKGROUND: Proviral gene expression is a critical step in the retroviral life cycle and an important determinant in the efficiency of retrovirus based gene therapy vectors. There is as yet no method described that can assess the efficiency of proviral gene expression while vigorously excluding the contribution from unstable species such as passively transferred plasmid and LTR circles. Here, we present a method that can achieve this. RESULTS: Proviral gene expression was detected by the activity of the puromycin resistance gene encoded in the viral vector, and quantified by comparing the growth curve of the sample under puromycin selection to that of a series of calibration cultures. Reproducible estimates of the efficiency of proviral gene expression could be derived. We confirm that contamination from unstable species such as passively transferred plasmid used in viral vector production and unintegrated viral DNA can seriously confound estimates of the efficiency of transduction. This can be overcome using a PCR based on limiting dilution analysis. CONCLUSION: A simple, low cost method was developed that should be useful in studying the biology of retroviruses and for the development of expression systems for retrovirus based gene therapy
