The secondary amphipathic peptide CADY forms stable positively charged nanoparticles with short interfering RNA (siRNA), which involves both electrostatic and hydrophobic interactions. CADY/siRNA self-assembling nanoparticles adopt a "raspberry"-like architecture cemented together by a matrix of free peptides. These nanoparticles are nontoxic and promote efficient delivery of siRNA in challenging primary ...

Mechanistic understanding of consumer-resource dynamics is critical to predicting the effects of global change on ecosystem structure, function and services. Such understanding is severely limited by mechanistic models' inability to reproduce the dynamics of multiple populations interacting in the field. We surpass this limitation here by extending general consumer-resource network ...

Background: DDT's (dichlorodiphenyltrichloroethane) association with breast cancer is controversial, but animal studies directly linking DDT to risk are lacking. Concerns with DDT reside in its environmental persistence, bioaccumulation in breast adipose tissue, and endocrine disrupting actions. Although most attention has been focused on estrogenic congeners, our study tested the cancer-inducing ...

Triple-T trick! Traceless tosylhydrazone-based triazole formation is readily achieved by reacting primary amines with functional α,α-dichlorotosylhydrozones under ambient conditions. This fast and efficient alternative affords exclusively 1,4-substituted triazole "click products" with complete retention of configuration. Primary amines, inherent to many natural products, can be modified in this way without protecting ...
