Phthalates are the materials used for plasticizing polyvinyl chloride. Di-(2-Ethylhexyl) phthalate (DEHP) is one of the phthalates most frequently used in a wide range of applications, including medical equipment such as endotracheal and feeding tubes, intravenous catheters, central lines, extracorporeal membrane oxygenation sets, total parenteral nutrition bags, blood product sets, and intravenous pump lines, respiratory sets in neonatal intensive care units (NICUs). Studies have shown that phthalates, including DEHP, can cross the placenta and blood-brain barrier, possibly leading to neurodevelopmental impairment in vitro and in vivo. However, the molecular mechanisms affected by phthalate exposure have not been explored in depth. This study aimed to illuminate the effects of DEHP on neuroinflammation at the molecular level using neonatal microglial cells as the model. ⋯ This study indicates that neonatal exposure to DEHP may be linked to neurodevelopmental impairment via inflammation-related cell death and ferroptosis. The prevalence of DEHP in NICU medical devices raises concerns about potential neurodevelopmental deficits, including disorders like autism and mental retardation. These findings highlight the urgency of addressing DEHP exposure in neonatal care.

In practice, waiting 2-3 weeks for interpolation flaps pedicle division result in certain morbidities and discomfort for patient. The division time of flap pedicle depends on neovascularization from the recipient bed and includes wound healing stages. We aimed to investigate the effect of recombinant human epidermal growth factor (rhEGF) on the flap viability during early pedicle division. ⋯ Following the application of EGF, the necrosis area decreased within the study group. Histopathological assessments revealed a statistically significant increase in parameters related to granulation tissue and fibroblastic activity, notably neovascularization, across all subgroups within the study. It was concluded that the use of EGF positively affected the neovascularization, and flaps could be divided earlier.

Doxorubicin (Dox) is a potent anticancer medication. However, due to nephrotoxicity, its clinical application is restricted. Achillea millefolium (AM) is a plant used in traditional medicine to treat several conditions, including kidney disorders. The aim of this work was to investigate the preventative properties of AM extract (AME) and their mechanisms against nephrotoxicity caused by Dox in rats. ⋯ AME could protect against nephrotoxicity caused by Dox by reducing oxidative stress, stimulating antioxidant mechanisms, and suppressing proinflammatory cytokines, suggesting that AME may be useful as an adjuvant therapy for Dox-induced nephrotoxicity.

Medication overuse is common among chronic migraine patients and nonsteroidal antiinflammatory drugs (NSAIDs) are the most frequently overused drugs. The pathophysiological mechanisms underlying medication overuse headache (MOH) are not completely understood. Intestinal hyperpermeability and leaky gut are reported in patients using NSAIDs. The aim of the study is to investigate the role of leaky gut and inflammation in an MOH model MOH model in male rats. ⋯ Elevated serum occludin and LBP levels and brain IL-17 and HMGB1 levels indicate a possible role of leaky gut and inflammation in an MOH model in male rats. Additionally, a significant correlation between pain behavior and markers of inflammation and intestinal hyperpermeability, supports the role of inflammation and leaky gut in MOH pathophysiology.
