The effects of skin ageing are mostly encountered in the superficial dermis and in the epidermis. We have previously demonstrated in vivo the beneficial effect of a topically applied formula of 5% vitamin C in the treatment of skin ageing. Another active compound, madecassoside extracted from ...
For galactooligosaccharides, no clear dosage regulation is established for their use in general adult foods in various countries, but the addition amount is specifically limited in infant formula foods. The content of galactooligosaccharides in infant milk powder should usually be less than that in ...

The membrane-integral glycerol 3-phosphate (G3P) acyltransferase PlsY catalyses the committed and essential step in bacterial phospholipid biosynthesis by acylation of G3P, forming lysophosphatidic acid. It contains no known acyltransferase motifs, lacks
(NH4)2V6O16. Before the V2O5synthesis at 450 °C, the solid product bears the empirical formula of ammonium hexavanadate (AHV) [39]. When the temperature was increased to 450 °C, the sample did not reveal any change in the weight, indicating that the V2O5product was stable. Between ...
Tauc’s formula was applied to determine the optical energy bandgaps (Eg) of the produced La2O3-ZnO nanostructured samples [34,35]: 𝐹(𝑅)=(1−𝑅)22𝑅=𝐾𝑆,F(R)=(1−R)22R=KS, (4) 𝛼=𝐹(𝑅)𝑡,α=F(R)t, (5) (𝛼ℎ𝜈)1/𝑛=𝐴1/𝑛(ℎ...
Figure 2. Sulfation modified polysaccharide reaction formula. 2.1.1. Chlorosulfonic Acid–Pyridine Method The chlorosulfonic acid–pyridine method is the most commonly used sulfation method [24]. The sulfonated reagent is prepared in a low-temperature environment by adding a specific proportion of chlo...
Density functional theory (DFT) calculations and molecular docking have been carried out on natural products containing eugenol, gingerol, ascorbic acid, o
Where TV is the tumor volume, a is the shorter diameter and b is the longer diameter. To compare tumor growth inhibiting activity between the experimental groups, tumor growth inhibition values were estimated using the following formula:
Structural analysis by NMR spectroscopy ( 1 H, 13 C, COSY , HETCOR and DEPT) suggests that the compound is composed of 3 threose residues and 2 N- α -acetyllysines with an empirical formula of C 28 H 45 N 4 O 12 . The compound, referred to as threosidine (2,5-dihydroxy-5,6...
