During the COVID-19 pandemic, the rapid surge in demand for critical supplies and public health efforts needed to guard against virus transmission have placed enormous pressure on health systems worldwide. These pressures and the uncertainty they have created have impacted the health workforce in a substantial way. This paper examines the relationship between health supply chain capacity and the impact of the COVID-19 pandemic on Canada's health workforce. The findings of this research also highlight the impact of the pandemic on health workers, specifically the relationship between the health supply chain and the autonomy of the health workforce.The Canadian Institute for Health Information has compiled health system data to investigate the impact of the COVID-19 pandemic on Canada's healthcare system. Information was aggregated from four distinct sectors of care emergency department visits, in-patient hospital stays, physician care and home care. Across the sectors, there were two compelling themes rapid transformation and change in human behaviour.The COVID-19 pandemic has highlighted the need for a robust and nimble public health data infrastructure. ICES - a government-sponsored, independent, non-profit research institute in Ontario, Canada - functions as a key component of a resilient information infrastructure and an enabler of data co-production, contributing to Ontario's response to the COVID-19 pandemic as part of a learning health system. Linked data on the cumulative incidence of infection and vaccination at the neighbourhood level revealed disparate uptake between areas with low versus high risk of COVID-19. These data were leveraged by the government, service providers, media and the public to inform a more efficient and equitable vaccination strategy.This issue of Healthcare Quarterly includes instructive research results, statistical analyses and case-study insights within and without the COVID-19 context. It also strikes a highly humanistic tone, a reminder that relationships are at the core of healthcare and that providing and receiving healthcare are profoundly personal and consequential. Organizing, running and resourcing healthcare require strong interpersonal and collective connections, shared accountabilities and agreement on goals that aim for a coherent, continuously improving health system and a safe, fair and caring place to work and heal.Cellulosomes are highly complex cell-bound multi-enzymatic nanomachines used by anaerobes to break down plant carbohydrates. The genome sequence of Ruminococcus flavefaciens revealed a remarkably diverse cellulosome composed of more than 200 cellulosomal enzymes. Here we provide a detailed biochemical characterization of a highly elaborate R. flavefaciens cellulosomal enzyme containing an N-terminal dockerin module, which anchors the enzyme into the multi-enzyme complex through binding of cohesins located in non-catalytic cell-bound scaffoldins, and three tandemly repeated family 16 glycoside hydrolase (GH16) catalytic domains. The DNA sequence encoding the three homologous catalytic domains was cloned and hyper-expressed in Escherichia coli BL21 (DE3) cells. SDS-PAGE analysis of purified His6 tag containing RfGH16_21 showed a single soluble protein of molecular size ~89 kDa, which was in agreement with the theoretical size, 89.3 kDa. The enzyme RfGH16_21 exhibited activity over a wide pH range (pH 5.0-8.0) and a broad temperature range (50-70 °C), displaying maximum activity at an optimum pH of 7.0 and optimum temperature of 55 °C. Substrate specificity analysis of RfGH16_21 revealed maximum activity against barley β-d-glucan (257 U mg-1) followed by lichenan (247 U mg-1), but did not show significant activity towards other tested polysaccharides, suggesting that it is specifically a β-1,3-1,4-endoglucanase. TLC analysis revealed that RfGH16_21 hydrolyses barley β-d-glucan to cellotriose, cellotetraose and a hig
