Rapid and accurate diagnostics are needed to effectively detect and treat primary amoebic meningoencephalitis (PAM) caused by (). Delayed diagnosis and similarities to other causes of meningitis contribute to a case mortality rate of >97%. Thus, there is an unmet medical need for a non-invasive liquid biopsy diagnostic method.

- - Malaria, caused by the Plasmodium parasite, faces challenges due to drug resistance, prompting the need for new treatments targeting both symptomatic and asymptomatic liver stages; a cost-effective luciferase detection method for liver stage screening has been developed using common lab reagents.
- - The study optimized a protocol for testing liver stage parasites, validating it with 28 existing anti-malarials to ensure reliable signal data, enabling the screening of the Global Health Priority Box (GHPB) for potential drug candidates.
- - Results showed that the optimized screening method produced a more stable luciferase signal with lower cell density, identifying 9 promising hits with selective activity against the P. berghei liver stages.
parasites undergo development and replication within the hepatocytes before infecting the erythrocytes and initiating clinical malaria. Although type-I interferons (IFNs) are known to hinder infection within the liver, the underlying mechanisms remain unclear. Here, we describe two IFN-I-driven hepatocyte antimicrobial programs controlling liver-stage malaria.

However, routine clinical evaluation for dystonia in CP has failed to match these expected numbers. Addressing this diagnostic gap is a medical imperative because the presence of dystonia rules in or out certain treatments for motor symptoms in CP.

The effect of this loss is most consequential during early-life, as initial colonizers of the newborn gut contribute significantly to the development of the immune system.
Methods: In this longitudinal study (day 3, week 3, and month 3 post-birth) of infants of Asian ancestry born in Singapore, we studied how generational immigration status and common perinatal factors affect bifidobacteria and subsp.
