“Aims: To identify the phenolic compounds in the leaves of Sphagnum papillosum and examine their antibacterial activity at pH appropriate for the undissociated forms.
Methods click here and Results: Bacterial counts of overnight cultures showed that whilst growth of Staphylococcus aureus 50084 was impaired in the presence of milled leaves, the phenol-free fraction of holocellulose of S. papillosum had no bacteriostatic effect. Liquid chromatography-mass spectrometry analysis of an acetone-methanol extract of the leaves detected eight phenolic compounds. Antibacterial activity of the four dominating phenols specific to Sphagnum leaves, when assessed in vitro as minimal inhibitory concentrations (MICs), were generally >2.5 mg ml(-1). MIC values of the Sphagnum-specific compound ‘sphagnum acid’ [p-hydroxy-beta-(carboxymethyl)-cinnamic GDC-0973 ic50 acid] were >5 mg ml(-1). No synergistic or antagonistic effects of the four dominating phenols were detected in plate assays.
Conclusions: Sphagnum-derived phenolics exhibit antibacterial activity in vitro only at concentrations far in excess of those found in
the leaves.
Significance and Impact of the Study: We have both identified the phenolic compounds in S. papillosum and
assessed their antibacterial activity. Our data indicate that phenolic compounds in isolation are not potent antibacterial agents and we question their potency against food-borne pathogens.”
“Differences in transduction and transmission latencies of visual, auditory and tactile events cause corresponding differences in simple reaction time. As reaction time is usually measured in unimodal blocks, it is unclear whether such latency differences also apply when observers monitor multiple sensory channels. We investigate this by comparing reaction time when attention is focused on a single modality, and when attention is divided between multiple no modalities. Results show that tactile reaction time is unaffected by dividing attention, whereas visual and auditory reaction times are significantly and asymmetrically increased. These findings show that tactile information is processed preferentially by the nervous system under conditions of divided attention, and suggest that tactile events may be processed preattentively.

“The ezrin-radixin-moesin (ERM) proteins are a family of widely distributed membrane-associated proteins and have been implicated not only in cell-shape determination but also in signaling pathway. The nucleus accumbens (NAcc) is an important neuronal substrate mediating the effects of drugs of abuse.
