Background: Parturition is similar to an inflammatory response in which resident and infiltrating immune cells release cytokines and chemokines into the maternal-fetal interface, promoting expulsion of the fetus from the mother. The untimely activation of these inflammatory pathways can result in preterm labor. The maternal-fetal interface is composed mainly of decidual tissue and placental villous space.

Carbonyls can be emitted by human activities or produced by photochemical oxidation. However, there is a lack of accurate methods for separately analyzing the primary and secondary sources of carbonyls, which is important for industrial cities with large carbonyls emission. Combined the method of multiple linear regression, positive matrix factorisation (PMF) and observation-based model (OBM), this study improved the source apportionment method of carbonyl and conducted research in a typical industrial city in North China during different seasons.

The human brain exhibits heterogeneity across regions and network connectivity patterns; However, how these heterogeneities contribute to whole-brain network functions and cognitive capacities remains unclear. In this study, we focus on the regional heterogeneity reflected in local dynamics and study how it contributes to the emergence of functional connectivity patterns, network ignition dynamics of the empirical brains. We find that the level of synchrony among voxelwise neural activities measured from the fMRI data is significantly correlated with the transcriptional variations in excitatory and inhibitory receptor gene expression.

Alternative splicing contributes to complex traits, but whether this differs in trait-relevant cell types across diverse genetic ancestries is unclear. Here we describe cell-type-specific, sex-biased and ancestry-biased alternative splicing in ~1 M peripheral blood mononuclear cells from 474 healthy donors from the Asian Immune Diversity Atlas. We identify widespread sex-biased and ancestry-biased differential splicing, most of which is cell-type-specific.

Under China's strict industrial control measures, the reduction of secondary pollutants (O and secondary organic aerosols [SOA]) and precursors (volatile organic compounds [VOCs] and NOx) caused by industrial processes has encountered bottlenecks. In this study, the net O formation rate (Net [O]) in summer and the self-reaction rate between peroxy radicals (Self-Rnxs) in winter are used to characterize the formation potentials of O and SOA, respectively. Assuming that the precursor reduction ratio based on emission inventories is approximately equal to that based on observed concentrations, this study combines emission inventory and observation-based model (OBM) methods to indicate the potential source of secondary pollutants reduction.
