Phenotypic heterogeneity in fungi: importance and methodology

Phenotypic heterogeneity describes the variation that exists between individual cells, spores or other biological entities within genetically-uniform populations of fungi or other organisms. Studies over the last 10-15 years have successfully used laboratory- and modelling-based approaches to demonstrate the prevalence of phenotypic heterogeneity and characterise the molecular bases of the phenomenon (primarily centred around heterogeneous gene expression). In contrast to progress in these areas, the relevance of phenotypic heterogeneity for the competitive success of organisms in different natural scenarios, although widely speculated upon, has only recently begun to be investigated. This focus review addresses this latter question as tackled in recent studies with yeasts and filamentous fungi. We concentrate on the relevance to fungal activities such as survival against environmental stressors, pathogenesis, and spoilage. We also discuss methodologies for interrogating phenotypic heterogeneity in fungi. The emerging prevalence and apparent importance of fungal phenotypic heterogeneity provides a timely reminder that certain, potentially core aspects of fungal biology still remain widely under-explored

Effectiveness of fenugreek as a galactagogue: A network meta-analysis

Copyright © 2017 John Wiley & Sons, Ltd. A systematic review and network-meta analysis (NMA) were performed to test significance of the galactagogue effect of fenugreek administrated to lactating women versus other comparators (i.e., placebo/control/other galactagogues). A pairwise comparison for the treatment effect was carried out to generate the forest plot for the NMA. League tables were generated using treatment effect, weighted mean difference (WMD; 95% confidence interval, CI) for all pairwise comparisons, where WMD  >  0 favors the column-defining treatment. Five studies were identified with 122 participants receiving treatment with fenugreek. The NMA results of 4 studies indicated that consumption of fenugreek significantly increased amount of the produced breast milk [11.11, CI 95% 6.77, 15.46] versus placebo. The pairwise comparison revealed that fenugreek was effective as a galactagogue compared to placebo, control, and reference groups WMD 17.79 [CI 11.71, 23.88] . However, the effect of fenugreek was substantially inferior to Coleus amboinicus Lour and palm date. The NMA using pairwise comparison demonstrated the effect of C. amboinicus and palm date in the stimulation of the breast milk production was comparable and superior to all comparators
