Amorphous silica and crystalline silicalite (MFI structure) are demonstrated to be active and environmentally benign catalysts for propionic acid ketonisation at 450-500 °C to form 3-pentanone. The silicalite is particularly efficient, and its ketonisation selectivity is increased by base modification

In the hippocampus, metabotropic glutamate receptors (mGluRs) are involved in various forms of synaptic plasticity. High-fat diets (HFDs) adversely influence hippocampal structure and function and induce changes in hippocampal glutamate metabolism and neurotransmission. Here, we studied the induction of hippocampal

Animal-associated bacteria (microbiota) affect host behaviors and physiological traits. To identify bacterial genetic determinants of microbiota-responsive host traits, we employed a metagenome-wide association (MGWA) approach in two steps. First, we measured two microbiota-responsive host traits, development time and triglyceride (TAG)
