Background: This study updates the COVID-19 pandemic surveillance in East Asia and the Pacific we first conducted in 2020 with two additional years of data for the region.

Objective: First, we measure whether there was an expansion or contraction of the pandemic in East Asia and the Pacific region when the World Health Organization (WHO) declared the end of the COVID-19 public health emergency of international concern on May 5, 2023. Second, we use dynamic and genomic surveillance methods to describe the dynamic history of the pandemic in the region and situate the window of the WHO declaration within the broader history.

The Par complex regulates cell polarity in diverse animal cells , but how its localization is restricted to a specific membrane domain remains unclear. We investigated how the tumor suppressor Lethal giant larvae (Lgl) polarizes the Par complex in neural stem cells (NSCs or neuroblasts). In contrast to epithelial cells, where Lgl and the Par complex occupy mutually exclusive membrane domains, Lgl is cytoplasmic when the Par complex is apically polarized in NSCs.

Article Synopsis
  • Harm reduction for people who use drugs (PWUD) is a key strategy in US drug policy, focusing on meeting communities’ needs and providing various support services.
  • The Block-by-Block (BXB) intervention, launched in 2022 across five pilot areas in Illinois, aims to distribute naloxone and drug test strips in private or neutral settings to reduce opioid-related fatalities.
  • Early results show that the BXB initiative is feasible, with a 55% response rate at homes approached, and high acceptability, as 75% of those who answered were supportive of the intervention.
