    Targeting arginine auxotrophy in pancreatic cancer cells using human recombinant arginase I-induced arginine deprivation. (c2017) by Khalil, Nathalie

    Published 2017
    “…We have established that autophagy, a process of cellular destruction activated in response to arginine deprivation, can be the leading cause of cell death at late drug incubation times. Hence, our study demonstrates that HuArgI (Co)-PEG5000 is a novel, potent and selective potential therapeutic approach for PC.…”

    Global, regional, and national burden of HIV/AIDS, 1990–2021, and forecasts to 2050, for 204 countries and territories: the Global Burden of Disease Study 2021 by Austin, Carter

    Published 2024
    “…Additionally, we introduced two new metrics to our reporting: prevalence of unsuppressed viraemia (PUV), which represents the proportion of the population without a suppressed level of HIV (viral load <1000 copies per mL), and period lifetime probability of HIV acquisition, which quantifies the hypothetical probability of acquiring HIV for a synthetic cohort, a simulated population that is aged from birth to death through the set of age-specific incidence rates of a given time period. FindingsGlobal new HIV infections decreased by 21·9% (95% UI 13·1–28·8) between 2010 and 2021, from 2·11 million (2·02–2·25) in 2010 to 1·65 million (1·48–1·82) in 2021. …”
