The Restylane® portfolio of hyaluronic acid (HA) fillers comprises a broad range of products, each with a unique combination of gel strength/firmness and flexibility. Restylane® Shaype™ (HASHA) is a new HA injectable produced with NASHA-HD™ technology and the most recent addition to the Restylane portfolio. NASHA-HD is an evolution of the NASHA™ platform that adds more HA and uses a more efficient cross-linking even though the degree of modification is kept low.

Purpose: Optimizing outcomes of aesthetic treatments with injectable products usually requires a consideration of the entire face to ensure balance, along with combination treatments that align with the patient's goals. To help injectors, a method of assessing the patient and developing an individualized, holistic treatment plan was developed. This methodology is termed Assessment, Anatomy, Range, and Treatment (AART™) and Holistic Individualized Treatments (HITs™).

Primary tumors can inhibit the growth of secondary lesions, particularly metastases, in a phenomenon termed "concomitant resistance". Several mechanisms have been proposed for this effect, each supported by experimental data. In this paper, we hypothesize that concomitant resistance is a form of hormesis, a biphasic dose response in which a stimulus has a positive and/or stimulatory effect at low dosages and a negative, inhibitory, and/or toxic effect at higher dosages.

Article Synopsis
  • * In experiments on glioblastoma mice, Q0/A significantly reduced tumor growth and improved survival rates, demonstrated by increased oxidative stress specifically in the tumor and increased blood flow to the tumor.
  • * The treatment showed stronger anticancer effects compared to a previous method (menadione/ascorbate) and had no noticeable side effects, suggesting it could be a safe option for targeted glioblastoma therapy.

Article Synopsis
  • The study introduces a new approach to cancer treatment that targets cancerous mitochondria using "mitocans," specifically redox-cycling quinone/ascorbate (Q/A) pairs, which primarily harm cancer cells while sparing normal cells.
  • Eleven different Q/A combinations were tested on both cultured cancer cells and mice with tumors, leading to a significant reduction in cancer cell growth and survival without major negative effects on healthy cells.
  • The findings highlight that certain Q/A pairs, particularly benzoquinone/ascorbate, induce harmful oxidative stress in cancer cells while showing tolerable impacts on normal cells, attributed to changes in mitochondrial behavior and specific interactions within cancer cells.
