Enhanced Electrochemiluminescence by Knocking Out Gold Active Sites.

Electrochemiluminescence (ECL) of the conventional system of [Ru(bpy)3]2+ luminophore and amine-based coreactants is particularly inefficient on noble metal electrodes. This is due to the formation of a passivating oxide layer on the metal surface inhibiting the electro-oxidation of amines like tri-n-propylamine (TPrA) coreactant, Herein, we demonstrated the enhancement of ECL emission on gold surface by hydroxyl radicals attack that are chemically generated with Cu-Fenton reagent. These radicals selectively deactivate the gold active sites and knockout the metal surface asperities that counterintuitively led to an amplification of the ECL emission.

A review of portal vein embolization prior to hepatic resection.

Primary and metastatic liver cancers are increasing in incidence, and the approaches with the longest survival are resection and transplantation. Posthepatectomy liver failure (PHLF) is the leading cause of mortality following liver resection. PHLF is largely due to liver insufficiency due to the insufficient size of the future liver remnant (FLR).

Uterine window and placenta accreta spectrum in a dichorionic, diamniotic twin gestation complicated by postpartum hemorrhage.

Cesarean scar defects encompass a spectrum of separation of the uterine layers that increase risk of uterine rupture during labor and delivery. When coupled with the presence of placenta accreta spectrum, a condition characterized by abnormal adherence to or invasion of the myometrium by the placenta, the risk of life-threatening hemorrhage significantly increases. As rates of cesarean delivery increase, it is important to understand the imaging findings typical of both conditions.

Post COVID-19 Pandemic and Intimate Partner Violence: Family Physician to Its Rescue.

COVID-19 has created panic waves wherein the world is under test and Malaysia is no exception. Intimate partner violence (IPV) is one among the exhaustive list and seen rise in cases especially after the lockdown where families must spend more time with each other. Good news that the movement restrictions are lifted, meanwhile it is likely that family physicians can expect more admissions of IPV.
