Binge eating, eating an abnormally large amount of food in a discrete period of time with a sense of loss of control over eating, is a defining feature of the eating disorders binge eating disorder (BED) and bulimia nervosa (BN). Both BED and BN are important public health problems for which there are few medical treatments. However, almost all drugs with central nervous system-mediated weight loss properties studied thus far in randomized, placebo-controlled trials in persons with BED or BN have been efficacious for reducing binge eating behavior...

BACKGROUND: Radiolabeled anti-myosin imaging is well-established for imaging doxorubicin-induced cardiotoxicity. However, to enable imaging of drug-induced cardiotoxicity in small experimental animals, pretargeting with bispecific anti-myosin-anti-DTPA-Fab-Fab' and targeting with high-specific radioactivity Tc-99m-DTPA-succinylated-polylysine (DSPL) was developed. METHODS: Mice were injected biweekly with 10 mg/kg Dox or its equivalent as D-Dox-PGA. Tc-99m-DSPL myocardial activity after pretargeting with bsAb-Fab-Fab' was determined after gamma imaging performed at day 7 for Dox-treated mice and day 39 for all others...

Etoposide is a cancer-targeting drug but an overdose of etoposide leads to immunosuppression in patients. Therefore, the development of a new strategy to enhance its anticancer effect, while in the meantime alleviating its adverse effects, is important but challenging. In this work, with the assistance of a hydrogelator precursor Nap-Phe-Phe-Tyr(H2PO3)-OH (1P), etoposide phosphate (EP) was subjected to alkaline phosphatase (ALP)-triggered assembly, which obviously enhanced its anticancer efficacy in vitro and in vivo...
