Curcumin mimics of potential chemoprevention with NQO1 induction properties.
Sci Rep

Department of Pesticide Chemistry, National Research Centre, Dokki, 12622, Giza, Egypt.
Chemoprevention is one of the accessible strategies for preventing, delaying or reversing cancer processing utilizing chemical intervention of carcinogenesis. NAD(P)H quinone oxidoreductase 1 (NQO1) is a xenobiotic metabolizing cytosolic enzyme/protein with important functional properties towards oxidation stress, supporting its ability in detoxification/chemoprotective role. A set of 3,5-diylidene-4-piperidones (as curcumin mimics) bearing alkyl sulfonyl group were synthesized with potential NQO1 induction properties.

Ileo-ileal intussusception and necrotising enterocolitis after indomethacin exposure masquerading clinically as solitary intestinal perforation.
BMJ Case Rep

Department of Paediatric Surgery, KK Women's and Children's Hospital, Singapore.
We report a case of small bowel perforation from ileo-ileal intussusception with necrotising enterocolitis (NEC) after indomethacin exposure mimicking spontaneous intestinal perforation in an extremely preterm neonate. Indomethacin exposure can cause mesenteric hypoperfusion, resulting in an ischaemic lead point for intussusception and NEC. We advocate that intussusception should be considered as one of the differentials for neonates with recurrent feeding intolerance postindomethacin exposure.

The incorporation of a glassy material into a self-assembled nanoparticle (NP) film can produce highly loaded nanocomposites. Reduction of the NP diameter can lead to extreme nanoconfinement of the glass, significantly affecting the thermal and physical properties of the nanocomposite material. Here, we investigate the photostability and photodegradation mechanisms of molecular nanocomposite films (MNCFs) produced from the infiltration of indomethacin (IMC) molecules into self-assembled films of silica NPs (11-100 nm in diameter).

Amniotic fluid assessment is crucial in prenatal ultrasound to monitor fetal conditions, with polyhydramnios, characterized by excessive amniotic fluid, affecting 1%-2% of pregnancies. Polyhydramnios is linked to complications such as placental abruption, preterm labor, congenital anomalies, and postpartum hemorrhage, emphasizing the need for early detection and management. While idiopathic causes account for 60%-70% of cases, other causes include impaired fetal swallowing and increased urine production due to maternal, fetal, and placental conditions.
