Bacterial nucleoid-associated proteins, such as H-NS-like proteins in Enterobacteriaceae, are abundant DNA-binding proteins that function in chromosomal DNA organization and gene transcription regulation. The Mycobacterium tuberculosis Lsr2 protein has been proposed to be the first identified H-NS analogue in Gram-positive

High-protein diets induce alterations in metabolism that may prevent diet-induced obesity. However, little is known as to whether different protein sources consumed at normal levels may affect diet-induced obesity and associated co-morbidities.

We describe a route towards self-assembled colloidal molecules, where thermoresponsive microgels serve as discrete, externally tunable interaction sites. The ability of poly(N-isopropylacrylamide) (PNIPAM) and poly(N-isopropylmethacrylamide) (PNIPMAM) microgels to adsorb to the oil/water (O/W) interface and create Pickering-stabilized mini-emulsions was first
