    “…Forty male C57BL/6J mice were fed a normal diet (ND, n = 10), high-fat diet (HFD, 60% fat, w/w, n = 10), HFD supplemented with 200 mg/kg of SGE or garcinia (GAR) by weight (SGED or GARD, respectively, n = 10) for 12 weeks. Serum chemistry was examined, and the expressions of genes involved in lipid metabolism were determined in the liver. …”

    “…However, the deep microbial community is still largely unknown and can be influenced by parameters such as temperature, pressure, water residence times, and chemistry of the waters. In this study, 21 boreholes representing a range of deep continental groundwaters from the Äspö Hard Rock Laboratory were subjected to high-throughput 16S rRNA gene sequencing to characterize how the different water types influence the microbial communities. …”

    “…In terms of individual mol­ecules, O⋯H/H⋯O contacts are more important for the TDBA (ca 28%) than for the TPPO mol­ecules (ca 13%), as expected from the chemical composition of these species. Computational chemistry indicates the four independent hy­droxy-O—H⋯O(oxide) hydrogen bonds in the crystal impart about the same energy (ca 52 kJ mol(−1)), with DTBA-phenyl-C—H⋯O(oxide) inter­actions being next most stabilizing (ca 40 kJ mol(−1)).…”
