Discovery and screening of the humimycins. Top: the humimycins were predicted from closely related gene clusters found in two Rhodococcus spp. cultured from human subjects. Center: chemical structures of humimycin A and B; the two antibiotics differ only at the fourth (F or Y) and sixth (V or I) residues. Bottom: MIC values for the humimycins against a panel of human commensal and pathogenic bacteria; the humimycins were particularly active against bacteria in the Staphylococcus and Streptococcus genus.

In the study, whole-brain degree count maps, collected before the start of treatment, were used to identify potential brain regional markers for placebo propensity. Group differences in whole-brain maps for degree count (number of connections of any location to the rest of the brain) between placebo responders and non-responders identified four brain regions that differentiated placebo responders from non-responders. The highest significant difference was seen for the right midfrontal gyrus. Abbreviations: r-MFG - right midfrontal gyrus; ACC - anterior cingulate cortex; PCC - posterior cingulate cortex; r-S2/M1 - right secondary somatosensory and primary motor cortex.
