The assessment of the effect of a cosmetic product brightening the skin of people with discolorations of different etiology.

Background: Hyperpigmentations are disorders displayed with a change in the color of the skin, its strange shape, the lack of symmetry, and irregular placement. They appear no matter on the age, gender, and often as a congenital defect. Disorder connected with overproduction of melanin by pigmentary cells.

A study of the activity and effectiveness of recombinant fibroblast growth factor (Q40P/S47I/H93G rFGF-1) in anti-aging treatment.

Introduction: Fibroblast growth factor 1 (FGF-1) is a powerful mitogen involved in the stimulation of DNA synthesis and the proliferation of a wide variety of cell types. Fibroblast growth factor 1 was genetically modified to improve its thermal stability and resistance to protease degradation without losing its biological activity.

Aim: To study the impact of Q40P/S47I/H93G rFGF-1 on skin cells, its penetration through the skin and the evaluation of the rFGF-1-cosmetic product properties.

Roxithromycin-loaded lipid nanoparticles for follicular targeting.

Particulate drug carriers e.g. nanoparticles (NPs) have been shown to penetrate and accumulate preferentially in skin hair follicles creating high local concentration of a drug.

Age-Related Changes in the Mechanical Properties of Human Fibroblasts and Its Prospective Reversal After Anti-Wrinkle Tripeptide Treatment.

One of an essential characteristic of human skin are time dependent mechanical properties. Here, we demonstrate that stiffness of human dermal fibroblast correlates with age and it can be restored after anti-wrinkle tripeptide treatment. The stiffness of human fibroblasts isolated from donors of 30-, 40- and 60 years old were examined.

The essential endoplasmic reticulum chaperone Rot1 is required for protein N- and O-glycosylation in yeast.

Rot1 is an essential yeast protein originally shown to be implicated in such diverse processes such as β-1,6-glucan synthesis, actin cytoskeleton dynamics or lysis of autophagic bodies. More recently also a role as a molecular chaperone has been discovered. Here, we report that Rot1 interacts in a synthetic manner with Ost3, one of the nine subunits of the oligosaccharyltransferase (OST) complex, the key enzyme of N-glycosylation.

Defect in dolichol-dependent glycosylation increases sensitivity of Saccharomyces cerevisiae towards anti-fungal drugs.

Two temperature-sensitive Saccharomyces cerevisiae mutants, sec59-1 and dpm1-6, impaired, respectively, in dolichol kinase (Sec59p) and dolichyl phosphate mannose (DolPMan) synthase (Dpm1p), have an aberrant cell wall structure and composition. We tested their sensitivity to four classes of antifungal drugs used in clinical practice: 5-fluorocytosine, amphotericin B, caspofungin and itraconasole. The strains were resistant to itraconazole and sensitive to the other drugs used.
