Although there have been several experimental and numerical works on rapidly rupturing films, measurement of the spatial-temporal temperature during rupturing processes is lacking. Using molecular dynamics simulations, we show that a rupturing film with nanometer thickness generates a non-negligible temperature increase. We demonstrate a correlation between the rupture velocity, the temperature increase, and the initial film thickness. Our findings show that the temperature increase causes changes to the physical properties, which affect the film-rupturing behavior.

The Emerging Role of Multimodality Imaging in the Diagnosis and Management of Post Pericardiotomy Syndrome.
Curr Cardiol Rep
January 2025
Division of Cardiology, McGill University Health Centre, 845 Rue Sherbrooke O, Montreal, QC, H3H 0G4, Canada.
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.
Giant Seebeck Effect of Dibenzo[g,p]chrysene and its Derivatives: Deuteration and Substituent Effects and Relationship with Interlayer Distance.

Kanagawa University, Department of Chemistry, JAPAN.
Thermoelectric properties of undoped crystals of dibenzo[g,p]chrysene (DBC), deuterated DBC (DBC-d16), and 2,10-dimethyl-DBC (DBC-Me2) have been studied to obtain some insights into the relationship between the structural parameters of materials and the giant Seebeck effect. X-ray crystallography showed one-dimensional columnar packing with the interlayer distances (d) for DBC-d16, DBC, and DBC-Me2 were 3.78 Å, 3.

Panniculitides are a group of inflammatory disorders of the subcutaneous fat that have been reported as a rare complication of both a serine threonine kinase BRAF inhibitor monotherapy and BRAF inhibition in combination with a mitogen activated protein kinase (MEK) inhibitor combination therapy used to treat metastatic melanoma. The cutaneous manifestations of BRAF and BRAF/MEK therapies have been well documented, but neutrophilic panniculitis remains a less common complication with fewer case reports. Physician awareness of this complication when following patients on similar targeted therapies can decrease delays in appropriate management.

Mosquito-borne flaviviruses represent a public health challenge due to the high-rate endemic infections, severe clinical outcomes, and the potential risk of emerging global outbreaks. Flavivirus disease pathogenesis converges on cellular factors from vectors and hosts, and their interactions are still unclear. Exosomes and microparticles are extracellular vesicles released from cells that mediate the intercellular communication necessary for maintaining homeostasis; however, they have been shown to be involved in disease establishment and progression.
