Background: Epithelioid angiosarcoma (EA) is an aggressive, malignant endothelial-cell tumor of vascular or lymphatic origin. EA often arises from deep soft tissues such as pleura, breast, bone and gastrointestinal tract. It usually affects patients aged 60-70 years and is associated with high recurrence and metastasis rates with surgical resection as the primary treatment of choice.

Introduction: Moderate aortic stenosis (AS) has traditionally been considered a stable condition, but recent evidence suggests that some patients progress rapidly to severe AS, leading to earlier symptom onset and worse outcomes. Current guidelines primarily focus on severe AS, leaving a gap in risk stratification for moderate cases. This study aims to identify echocardiographic and clinical predictors of rapid progression in moderate AS to refine patient selection for closer monitoring and early intervention.

Introduction: Many rare disorders, particularly neurodevelopmental conditions, manifest structural brain malformations. Just as dysmorphologists rely on facial gestalt recognition to identify syndromes, radiologists and neurologists face similar challenges in identifying the "brain gestalt" of rare disorders-especially when encountering rare conditions or those they have not previously seen. Next-generation phenotyping (NGP) has been proven capable of supporting clinicians in recognizing facial dysmorphic patterns associated with the underlying syndrome through training on thousands of patient photographs.

Background: Surgical resection of malignant lip tumors and the reconstruction of extensive lip defects in infants pose significant challenges. We evaluated the effectiveness of the Abbe-Estlander (A-E) flap in repairing upper lip defects in infants following oncosurgery.

Case Presentation: We present two cases of pediatric upper lip malignancies: an 18-month-old infant diagnosed with fibrosarcoma (FS) of the right upper lip (Case 1) and a 19-month-old infant diagnosed with rhabdomyosarcoma (RMS) of the left upper lip (Case 2).

Using a 266 nm laser, we simultaneously observe Raman and photoluminescence (PL) spectra of vertically aligned boron-nitride nanotubes (VA-BNNT) and single-walled carbon nanotubes (SWNT) encapsulated by boron nitride (VA-SWNT@BNNT). The larger PL intensity in VA-BNNT compared to that of the h-BN single crystal suggests that VA-BNNT contains more defect states. VA-SWNT@BNNT exhibits two multiphonon Raman peaks at 3033 and 3142 cm and four PL peaks at 4639, 5859, 6905, and 8293 cm.

Article Synopsis
  • Older patients with skin cancer often have other health issues, making tumor removal and reconstruction difficult.
  • This study assesses the safety and effectiveness of two surgical techniques, cervicofacial (CFF) and cervicothoracic (CTF) flaps, for repairing large facial defects in older patients.
  • Results showed both methods are reliable, with no complete flap failures and a majority of patients remaining disease-free post-surgery.

Article Synopsis
  • The study examines the use of extended vertical lower trapezius island myocutaneous flap (eTMF) for reconstructing significant soft tissue defects in the head and neck after removing extensive plexiform neurofibromas in patients with neurofibromatosis type 1 (NF1).
  • The surgical procedure showed positive outcomes, with improved facial aesthetics, function (such as swallowing and speech), and a notable increase in patients' quality of life post-surgery.
  • The results indicate that eTMF is a safe and effective method for enhancing both cosmetic appearance and social well-being after substantial tissue reconstruction.

Background: This retrospective clinical study performed at a single clinical center aimed to identify the prevalence of seizures in individuals with urea cycle disorders (UCDs) with and without hyperammonemic (HA) crises. In addition, we sought to correlate the utility of biochemical markers and electroencephalography (EEG) in detecting subclinical seizures during HA.

Methods: Medical records of individuals with UCDs enrolled in Urea Cycle Disorders Consortium Longitudinal Study (UCDC-LS) (NCT00237315) at Children's National Hospital between 2006 and 2022 were reviewed for evidence of clinical and subclinical seizuress during HA crises, and initial biochemical levels concurrently.

Establishing quantitative parameters for differentiating between healthy and diseased cartilage tissues by examining collagen fibril degradation patterns facilitates the understanding of tissue characteristics during disease progression. These findings could also complement existing clinical methods used to diagnose cartilage-related diseases. In this study, cartilage samples from normal, osteoarthritis (OA), and rheumatoid arthritis (RA) tissues were prepared and analyzed using polarization-resolved second harmonic generation (P-SHG) imaging and quantitative image texture analysis.

Charge density waves (CDWs) involved with electronic and phononic subsystems simultaneously are a common quantum state in solid-state physics, especially in low-dimensional materials. However, CDW phase dynamics in various dimensions are yet to be studied, and their phase transition mechanism is currently moot. Here we show that using the distinct temperature evolution of orientation-dependent ultrafast electron and phonon dynamics, different dimensional CDW phases are verified in CuTe.

Functional near infrared spectroscopy (fNIRS) and functional magnetic resonance imaging (fMRI) both measure the hemodynamic response, and so both imaging modalities are expected to have a strong correspondence in regions of cortex adjacent to the scalp. To assess whether fNIRS can be used clinically in a manner similar to fMRI, 22 healthy adult participants underwent same-day fMRI and whole-head fNIRS testing while they performed separate motor (finger tapping) and visual (flashing checkerboard) tasks. Analyses were conducted within and across subjects for each imaging approach, and regions of significant task-related activity were compared on the cortical surface.

Article Synopsis
  • Nanochannels that can control their opening and closing are useful in applications like detecting viruses, sorting particles, and regulating fluid flow.
  • The study investigates how changing the pH and ionic strength of solutions affects the behavior of a special brush coating inside these nanochannels.
  • Results show that at high pH, the brush is collapsed (like an open gate), while lower pH and salt levels cause the brush to expand and partially close the gate, offering new ways to design advanced nanofluidic devices.
