The Tree of Life Gateway uses Genome Note publications to announce the completion of genomes assembled by the Tree of Life programme, based at the Wellcome Sanger Institute and involving numerous partner organisations and institutes. Tree of Life participates in the Darwin Tree of Life Project, which aims to sequence the genomes of all 70,000+ eukaryotic species in the Atlantic archipelago of Britain and Ireland, the Aquatic Symbiosis Genomics Project, which will sequence 1000 species involved in 500 symbioses between eukaryotic hosts and their microbial 'cobionts', and other initiatives, such as the Vertebrate Genome Project. These Genome Notes report the origins of ethically sourced samples used for sequencing, give the methods used to generate the sequence and use statistics and interactive figures to demonstrate the quality of the genome sequences. In addition to describing the production of these sequences, each Genome Note gives citeable credit to those who participated in producing the genome assembly and announces the availability of the data for reuse by all. It is through the use and reuse of this openly and publicly released data that we hope effective and lasting solutions to the ongoing biodiversity crisis can be found.Late in 2020, two genetically-distinct clusters of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with mutations of biological concern were reported, one in the United Kingdom and one in South Africa. selleckchem Using a combination of data from routine surveillance, genomic sequencing and international travel we track the international dispersal of lineages B.1.1.7 and B.1.351 (variant 501Y-V2). We account for potential biases in genomic surveillance efforts by including passenger volumes from location of where the lineage was first reported, London and South Africa respectively. Using the software tool grinch (global report investigating novel coronavirus haplotypes), we track the international spread of lineages of concern with automated daily reports, Further, we have built a custom tracking website (cov-lineages.org/global_report.html) which hosts this daily report and will continue to include novel SARS-CoV-2 lineages of concern as they are detected.Background In India, stress levels are increasing steadily among youth. We aimed to explore the factors that contribute to psychological stress and coping strategies among adolescents in Mysore, India to inform the development of an intervention. Methods We recruited 16 volunteers in Mysore, India including 6 younger (12-15 years; 3 girls) and 10 older adolescents/ young adults (17-25 years; 5 girls) using a purposive sampling technique. Older adolescents were recruited from ongoing birth cohort study, and the younger adolescents by word-of-mouth from the community. Individual in-depth interviews were carried out based on a semi-structured interview guide comprising open-ended questions. The interviews were analysed to derive themes and emerging constructs related to stress and coping strategies. Results Adolescents generally perceived stress in their daily lives. Family conflicts and academic pressures were the main triggers for increased stress. Issues around peer relationships, and social position were also important contributors. Adolescents reported that they had robust coping strategies. These included stress release through rationalising and acceptance of the situation, distraction activities, spirituality, and self-comforting methods. However, they felt the need for further support from their family, and the society in general. In particular they expressed the need for a space to share their concerns and obtain guidance through healthy discussions with adults. Conclusions Our study indicates that adolescents in India are exposed to a wide range of stressors in their daily lives. The conflict between 'traditional' society's opinions of what adolescents should do and the new age adolescents' aspirations for autonomy to find 'informed' solutions for their issues may hinder the stress management efforts. Moving forward, we propose to develop a culturally acceptable intervention tool that accommodates adolescents' perspectives and psychosocial context.Background Animal models of stroke have been criticised as having poor predictive validity, lacking risk factors prevalent in an aging population. This pilot study examined the development of comorbidities in a combined aged and high-fat diet model, and then examined the feasibility of modelling stroke in such rats. Methods Twelve-month old male Wistar-Han rats (n=15) were fed a 60% fat diet for 8 months during which monthly serial blood samples were taken to assess the development of metabolic syndrome and pro-inflammatory markers. Following this, to pilot the suitability of these rats for undergoing surgical models of stroke, they underwent 30min of middle cerebral artery occlusion (MCAO) alongside younger controls fed a standard diet (n=10). Survival, weight and functional outcome were monitored, and blood vessels and tissues collected for analysis. Results A high fat diet in aged rats led to substantial obesity. These rats did not develop type 2 diabetes or hypertension. There was thickening of the thoracic arterial wall and vacuole formation in the liver; but of the cytokines examined changes were not seen. MCAO surgery and behavioural assessment was possible in this model (with some caveats discussed in manuscript). Conclusions This study shows MCAO is possible in aged, obese rats. However, this model is not ideal for recapitulating the complex comorbidities commonly seen in stroke patients.Background Interventions to promote physical activity are very limited in India. The objective of this study was to assess the effectiveness and sustainability of a peer support based physical activity (PA) intervention targeting sedentary women in Thiruvananthapuram City, India . Methods We used a non-randomized quasi-experimental study design with a comparison group. Using the Global Physical Activity Questionnaire (GPAQ) classifications, 401 sedentary women aged 18-64 years were selected by multistage cluster sampling and enrolled into the intervention (n=200) and control (n=201) arms. For the intervention arm, a culturally relevant intervention was delivered to the community stakeholders, participants and peer leaders at three subsequent intensities intense (three months), less intense (three months) and no intervention (six months). The intervention consisted of a non-communicable disease (NCD) risk assessment, educational workshop, group counselling sessions, goal setting, handbook and peer support. The control participants received printed information on NCDs and their risk factors.
