Co je měření studie?

Primární výstupní opatření

Měření výsledku
Popis opatření
Časové okno
Improvement in Non-invasive Skin Assessment of Skin Microperfusion
Časové okno: 14 weeks after oral supplementation
To see the improvement in noninvasive skin assessment of objective measurements such as skin microperfusion (laser speckle contrast imaging) (scale Pu). An increase in PU means improved perfusion of the skin.
14 weeks after oral supplementation
Improvement in Non-invasive Skin Assessment of Hydration
Časové okno: 14 weeks after oral supplementation
To see the improvement in noninvasive skin assessment of objective measurements such as skin hydration using the DermaLab Combo Series (unit of micro-Siemens uS), which are arbitrary. An increase in uS means improved skin hydration and improved skin barrier function.
14 weeks after oral supplementation
Improvement in Non-invasive Skin Assessment of Elasticity
Časové okno: 14 weeks after oral supplementation
To see the improvement in noninvasive skin assessment of objective measurements such as skin elasticity using the DermaLab Combo Series (mega Pascal mPa). An increase in mPA means worsening of skin elasticity.
14 weeks after oral supplementation
Improvement in Non-invasive Skin Assessment of Barrier Function
Časové okno: 14 weeks after oral supplementation
To see the improvement in noninvasive skin assessment of objective measurements such as barrier function using Trans-Epidermal Water Loss (TEWL) using the DermaLab Combo Series (g/m2/h). An increase in these units indicates a worsening of TEWL, and reduction of the barrier function of the skin.

Gene Chip Analysis- ITGA5 - Integrin Subunit Alpha 5
Časové okno: 14 weeks

We selected 17 genes of interest, and examined the difference in their expression in each interventional arm, compared to the placebo group. The results are listed in Arbitrary Units (AU), with each AU indicating an relative increase or decrease in gene expression compared to the control (reference comparator). The range is 0.0 to 80 AU.

The gene of interest examined here is ITGA5 - Integrin Subunit Alpha 5. Gene expression values cannot be directly interpreted as indicative of better or worse outcomes. However, based on the literature review, higher expression levels of the ITGA5 are predicted to be associated with improved outcomes related to extracellular matrix production.
