Giant cell tumors (GCTs) are common benign bone tumors found in young adults, frequently occurring in the long bones but rarely in the skull. Although considered benign, GCTs have the potential to be aggressive, destroying surrounding tissue. Here, we present the unusual case of a patient with a GCT of the middle ear and skull base. A 19-year-old male with an extensive giant cell tumor underwent surgical resection by a multidisciplinary team consisting of otolaryngology, neurosurgery, and plastic and reconstructive surgery. The mass was grossly resected, and a cervicofacial flap allowed for reconstruction with optimal cosmesis, a procedure not described for GCTs. This approach allowed for excellent wound healing without tumor recurrence. Gross total resection remains the most effective treatment for GCTs, minimizing radiation exposure and recurrence risk. However, an optimal surgical approach for skull GCTs has yet to be described. Skull-base GCTs present a challenge due to their complex anatomy and neurovascular elements. Further, the high rates of local recurrence make gross resection the goal of treatment, though this is difficult to achieve. The present case was successfully managed by extensive multidisciplinary surgical resection, highlighting the necessity of collaborative effects to achieve gross total resection and positive aesthetic outcomes.

Pb-free dielectric energy storage capacitors are core components in advanced pulse-power electronic systems and devices. However, the relatively low energy density (W) for the industrial pillar BaTiO (BT)-based capacitors remains a significant obstacle for their cutting-edge applications, due to their low intrinsic polarization and breakdown strength (E). Herein, through chemical composition and local structure design, a giant W of 15.

Sputnik virophages are small double-stranded DNA (dsDNA) viruses that replicate only inside host amoebae infected with giant dsDNA viruses, mimiviruses. Sputnik infection affects mimivirus replication, but their molecular interaction remains poorly understood. Here, we performed a time-course transcriptome analysis of cells infected with Acanthamoeba polyphaga mimivirus (APMV; hereafter referred to as Sputnik cells) and those infected with both APMV and Sputnik 3 virophage (Sputnik cells).

Creating artificial cells with a dynamic cytoskeleton, akin to those in living cells, is a major goal in bottom-up synthetic biology. In this study, we demonstrate the in situ polymerization of microtubules encapsulated in giant polymer-lipid hybrid vesicles (GHVs) composed of 1,2-dioleoyl-sn-glycero-3-phosphocholine and an amphiphilic block copolymer. The block copolymer is comprised of poly(cholesteryl methacrylate-co-butyl methacrylate) as the hydrophobic block and either poly(6-O-methacryloyl-D-galactopyranose) or poly(carboxyethyl acrylate) as the hydrophilic extension.

Objective: Platelet activation is thought to participate in polymyalgia rheumatica (PMR) pathogenesis. Upon platelet activation, mitochondria are expelled into the extracellular space. However, whether extracellular mitochondria are present in patients with PMR and whether they can induce platelet activation is not known.

Objectives: Both temporal artery biopsy (TAB) and imaging are widely used to support the diagnosis of giant cell arteritis (GCA). The objective of this study was to compare the use of TAB and imaging.
Methods: This article was based on a debate presented at the 21st Vasculitis Meeting, discussing the advantages and disadvantages of using TAB with histology vs imaging for the diagnosis of suspected GCA.
