Unlabelled: The aim of this study was to identify parameters influencing DNA extraction and PCR amplification efficiencies in an attempt to standardize Mucorales qPCR. The Fungal PCR Initiative Mucorales Laboratory Working Group distributed two panels of simulated samples to 26 laboratories: Panel A (six sera spiked with Mucorales DNA and one negative control serum) and Panel B (six Mucorales DNA extracts). Panel A underwent DNA extraction in each laboratory according to the local procedure and were sent to a central laboratory for testing using three different qPCR techniques: one in-house qPCR assay and two commercial assays (MucorGenius and Fungiplex).

Purpose: Grade 3 meningiomas, although rare, are associated with high morbidity and mortality. The respective impacts of extent of surgical resection and adjuvant radiotherapy are still debated. Moreover, anaplastic meningiomas are studied in heterogenous cohort of de novo and progressive anaplastic tumors.

Intestinal mucins play a crucial role in the mucosal barrier, serving as the body's initial defense against microorganisms. However, how the host regulates the secretion and glycosylation of these mucins in response to bacterial invasion remains unclear. Our study demonstrates that when exposed to (), a gut pathobiont, the host mucosa promptly adjusts the behavior of specialized goblet cells (GCs) located in the middle of the crypts.

Article Synopsis
  • Early pregnancy Zika virus (ZIKV) infection can cause serious brain damage in fetuses, resulting in conditions like microcephaly, though the exact mechanisms of this damage are still not fully understood.
  • A study using cynomolgus macaque fetuses showed that ZIKV was transmitted from infected fetuses to their mothers, leading to detectable viral levels in blood, brain, and placenta, along with signs of brain size reduction in the infected fetuses.
  • Despite persistent viral genetic material in tissues, the immune response helped clear much of the virus before the delivery, indicating that while short-term brain injury occurs, the body can partially control the infection.
