Spatial multiomic landscape of the human placenta at molecular resolution.

Successful pregnancy relies directly on the placenta's complex, dynamic, gene-regulatory networks. Disruption of this vast collection of intercellular and intracellular programs leads to pregnancy complications and developmental defects. In the present study, we generated a comprehensive, spatially resolved, multimodal cell census elucidating the molecular architecture of the first trimester human placenta.

Patients' recollection about the onset of Sjögren's disease - a mixed methods study on the patients' perspective.

Background: Little is known about the symptoms at the onset of Sjögren's Disease (SjD) and it is unclear whether SjD starts with characteristic symptoms that could be differentiated from dryness of other origin (sicca syndrome). The aim of this study was to investigate patients' recollection of initial events and first symptoms of SjD. The second aim was to verify and quantify these aspects in a representative cohort.

Brazilian version of the "Primary Sjögren's Syndrome - Quality of Life questionnaire (PSS-QoL)": translation, cross-cultural adaptation and validation.

Background: The Primary Sjögren's Syndrome Quality of Life questionnaire (PSS-QoL) is the first specific instrument to assess health-related quality of life (HRQoL) in Sjögren's disease (SjD). The aim is to translate and cross-culturally adapt the PSS-QoL into Brazilian Portuguese and to evaluate its psychometric properties.

Methods: The original English version was translated into Brazilian Portuguese by two native Brazilians who were proficient in the English language.

Small molecule inhibitor binds to NOD-like receptor family pyrin domain containing 3 and prevents inflammasome activation.

Despite recent advances in the mechanism of oxidized DNA activating NLRP3, the molecular mechanism and consequence of oxidized DNA associating with NLRP3 remains unknown. Cytosolic NLRP3 binds oxidized DNA which has been released from the mitochondria, which subsequently triggers inflammasome activation. Human glycosylase (hOGG1) repairs oxidized DNA damage which inhibits inflammasome activation.

Measuring Interactions Between Proteins and Small Molecules or Nucleic Acids.

Interactions between proteins and small molecules or nucleic acids play a pivotal role in numerous biological processes critical for human health and are fundamental for advancing our understanding of biological systems. Proteins are the workhorses of the cell, executing various functions ranging from catalyzing biochemical reactions to transmitting signals within the body. Small molecules, including drugs and metabolites, can modulate protein activity, thereby impacting cellular processes and disease pathways.
