Reduction of DILP2 in Drosophila triages a metabolic phenotype from lifespan revealing redundancy and compensation among DILPs [PDF]

, 2008
The insulin/IGF-like signalling (IIS) pathway has diverse functions in all multicellular organisms, including determination of lifespan. The seven insulin-like peptides (DILPs) in Drosophila are expressed in a stage- and tissue-specific manner.

Oxidation Resistance, Ablation Resistance, and Ablation Mechanism of HfC-B₄C-Modified Carbon Fiber/Boron Phenolic Resin Ceramizable Composites. [PDF]

Polymers (Basel)
Thermal protection materials with excellent performance are critical for hypersonic vehicles. Carbon fiber/phenolic resin composites (Cf/Ph) have been widely used as thermal protection materials due to their high specific strength and ease of processing. However, oxidative failure limits the extensive applications of Cf/Ph in harsh environments.
