Platelets are small in size and simple in structure. Nevertheless, these anucleate cytoplasts utilize complex molecular systems to regulate a variety of biological functions. Here we review evolutionary paths, traditional roles, and previously unrecognized biological capacities of platelets that interface thrombosis with inflammation and potentially identify new roles in inflammatory diseases.

Purpose Of Review: This review aims to evaluate current diagnostic and therapeutic strategies for postpericardiotomy syndrome (PPS), with a focus on the evolving role of multimodality imaging, including echocardiography, cardiac computed tomography (CCT), and cardiac magnetic resonance imaging (CMR). The review also explores the potential benefits of advanced imaging in improving the accuracy and management of PPS.
Recent Findings: PPS, a common complication following cardiac surgery, presents with pleuritic chest pain, fever, and pericardial or pleural effusion.

The mitochondrial outer membrane (OMM) β-barrel proteins link the mitochondrion with the cytosol, endoplasmic reticulum, and other cellular membranes, establishing cellular homeostasis. Their active insertion and assembly in the outer mitochondrial membrane is achieved in an energy-independent yet highly effective manner by the Sorting and Assembly Machinery (SAM) of the OMM. The core SAM constituent is the 16-stranded transmembrane β-barrel Sam50.

Background: X chromosome inactivation (XCI) is a female-specific process in which one X chromosome is silenced to balance X-linked gene expression between the sexes. XCI is initiated in early development by upregulation of the lncRNA Xist on the future inactive X (Xi). A subset of X-linked genes escape silencing and thus have higher expression in females, suggesting female-specific functions.

Synchrony in neuronal networks is crucial for cognitive functions, motor coordination, and various neurological disorders. While traditional research has focused on pairwise interactions between neurons, recent studies highlight the importance of higher-order interactions involving multiple neurons. Both types of interactions lead to complex synchronous spatiotemporal patterns, including the fascinating phenomenon of chimera states, where synchronized and desynchronized neuronal activity coexist.

The integration of crowdsourced data has become central to contemporary built environment studies, driven by the rapid growth in digital technologies and participatory approaches that characterize modern urbanism. Despite its potential, a systematic framework for its analysis remains underdeveloped. This review, conducted in accordance with the PRISMA protocol, examines the use of crowdsourced data in shaping the built environment, scrutinizing its applications, crowdsourcing techniques, methodologies, and comparison with other big data forms.
