BACKGROUND/AIM this study evaluated esophageal radioprotection by the Gramicidin S (GS) derived-nitroxide, JP4-039, a mitochondrial targeting peptide-isostere covalently-linked to 4-amino-Tempo, delivered in a novel swallowed oil-based (F15) formulation. MATERIALS AND METHODS C57BL/6HNsd female mice received intraesophageal F15 formulation containing JP4-039 (4 mg/ml in 100 microl volumes) 10...
OBJECTIVE Plasminogen activator inhibitor-1 (PAI-1), a serine protease inhibitor that promotes and inhibits cell migration, plays a complex and important role in adverse vascular remodeling. Little is known about the effects of pharmacological PAI-1 inhibitors, an emerging drug class, on migration of vascular smooth muscle cells (SMCs) and endothelial cells (ECs), crucial mediators of vascular ...
The characterisation of the risk of (new) chemicals to species/communities, when both the exposure/environmental concentration and effects (species sensitivity) are variable and uncertain, is the central issue in Probabilistic Environmental Risk Assessment. The spatial variability is one of the largest components of the total variability. This paper tries to explicitly account for this spatial ...
BACKGROUND/AIM To determine whether Gramicidin S (GS)-nitroxide, JP4-039, esophageal radiation protection protected lung tumors in a transgenic model, LoxP-Stoop-LoxP Kristen Rat Sarcoma Viral oncogene (LSL-K-RAS) mice were administered intra-tracheal- Carbapenem-resistant Enterobacteriaceae (CRE) recombinase, bilateral lung tumors were confirmed at 11 weeks, then thoracic irradiation was deliv...
It was unknown if a mitochondria-targeted nitroxide (JP4-039) could augment potentially lethal damage repair (PLDR) of cells in quiescence. We evaluated 32D cl 3 murine hematopoietic progenitor cells which were irradiated and then either centrifuged to pellets (to simulate PLDR conditions) or left in exponential growth for 0, 24, 48 or 72 h. Pelleted cells demonstrated cell cycle arrest with a ...
Background: Clefts of the lip, palate, or both are most prevalent form facial congenital abnormality among neonates. In improving health neonates born with craniofacial deformities, neonatal nurses played a crucial role in educating parents and spreading awareness about disease. Aim: to assess mothers' knowledge practices regarding cleft palate infant feeding patterns. The study was descriptive...
In carcinogenesis, inflammasomes may play contradictory roles through facilitating anti-tumor immunity or inducing oncogenic factors. Their function in cancer remains poorly characterized. In this study, we explored the effect of interleukin-17A (IL-17A) on the migration and invasion activity of nasopharyngeal carcinoma (NPC) cell lines and account for related mechanisms. Our results revealed t...
