Background And Introduction: Reduction mammaplasty surgery constitutes one of the plastic surgery procedures with the greatest impact on patients' quality of life. It is necessary to ensure an appropriate mammary contouring. Over time, various techniques have been proposed to overcome these problems, based mainly on the use of dermal, dermo fascial, or myoglandular flaps.

While multiple scoring systems exist to predict mortality in cardiac surgery, their utility in infective endocarditis (IE) remains uncertain, prompting this study to compare their prognostic accuracy. We conducted a comprehensive review using Ovid Medline, Embase, and Cochrane Central Register of Controlled Trials. Data were pooled using Open-Meta[Analyst] software, and calibration analysis was performed with Review Manager 5.

Background: Perivascular epithelioid cell tumors (PEComas) rarely appear in the head and neck region. This case report describes two transcription factor E3 (TFE3)-rearranged PEComa cases, consisting of one in the orbit and one in the nasal cavity.
Case Presentation: Both cases demonstrated sheet-like or focal nested architecture and comprised epithelioid cells with abundant clear to eosinophilic cytoplasm and vascular stroma.
Nucleosome repositioning in cardiac reprogramming.

Early events in the reprogramming of fibroblasts to cardiac muscle cells are unclear. While various histone undergo modification and re-positioning, and these correlate with the activity of certain genes, it is unknown if these events are causal or happen in response to reprogramming. Histone modification and re-positioning would be expected to open up chromatin on lineage-specific genes and this can be ascertained by studying nucleosome architecture.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by aggressive growth and metastasis, partly driven by fibroblast-mediated stromal interactions. Using RNA sequencing of fibroblasts from early-stage KPC mouse models, we identified significant upregulation of genes involved in adipogenesis, fatty acid metabolism, and the ROS pathway. ANGPTL4, a key adipogenesis regulator, was highly expressed in fibroblasts and promoted pancreatic cancer cell proliferation and migration through paracrine signaling.
