The curing process of hair-pin motor stator insulation is critical, as residual stress increases the risk of partial discharge and shortens a motor's lifespan. However, studies on the stress-induced defects during insulation varnish curing remain limited. This research integrates three-dimensional numerical simulations and experimental analysis to develop a curing model based on unsaturated polyester imide resin, aiming to explore the mechanisms of residual stress formation and optimization strategies.

Pityriasis rubra pilaris (PRP) presents a diagnostic challenge due to its varied clinical manifestations and the scarce literature on scalp involvement. This article presents a case report of a 59-year-old female with PRP solely affecting the scalp, detailing its clinical, trichoscopic, and histopathological features. Trichoscopy revealed a novel finding of white-silvery scales forming hair casts with a triangular shape, distinct from the existing literature.

Article Synopsis
  • Autosomal recessive congenital ichthyosis (ARCI) is a rare skin condition primarily characterized by skin scaling and hair abnormalities, which are often overlooked regarding their impact on patients' quality of life.
  • This study involved clinical and trichoscopic examinations of 30 ARCI patients over three years, revealing that alopecia affects a significant number, with various patterns of hair loss documented among participants.
  • Notable trichoscopic findings included scaling and different hair types that correlate with the severity of ARCI, suggesting that hair health is a crucial component of this condition often underestimated in prior research.

Article Synopsis
  • Systemic lupus erythematosus (SLE) is an autoimmune disease that predominantly affects women, with ongoing research into why this gender disparity exists and how ethnicity may affect the disease's clinical features.
  • A study of 89 childhood-onset SLE patients revealed that males had more instances of serositis and elevated anti-DNA antibodies, while females experienced more hair loss and lower average hemoglobin levels.
  • Despite differences in treatment, renal involvement appeared more commonly in males, indicating a need for further exploration of gender-specific manifestations and treatments in cSLE cases.
