3. Structure of prodigiosin from Serratia marcescens NJZT-1 and its cytotoxicity on TSC2-null cells
Abstract Prodigiosin, a secondary metabolite extracted from Serratia marcescens (S. marcescens), could induce apoptosis in various cancer cells, with however low toxicity on normal cells. The red pigment was extracted from a strain S. marcescens NJZT-1 isolated from soil, which had antibacterial activity. Spectral analyses (LC-ESI-MS, UV-VIS spectrophotometr

4. Nondestructive analysis of photosynthetic pigments in forage radish and vetch
ABSTRACT Chlorophylls and carotenoids are the main photosynthetic pigments in plants, and photosynthetic potential can be used to determine the nitrogen fixation or cycling capacity of cover crops. Therefore, this study quantified and compared the content of photosynthetic pigments in Raphanus sativus and Vicia sativa by using two different methods, namely t

8. The Anti-melanogenesis Activities of Some Selected Brown Macroalgae from Northern Coasts of the Persian Gulf
Abstract Melanogenesis is a biological process which led to the synthesis of melanin pigment. Abnormal melanin production results in melasma, solar lentigo, post inflammatory melanoderma, etc. In this study, we examined the potential inhibitory effects of 17 brown macroalgae from Persian Gulf on melanogenesis. The effects of various concentrations (100, 250

10. FOTOCATÁLISE MEDIADA POR TiO2 NO ESTADO NANOPARTICULADO: REVISÃO DA REATIVIDADE PELO CONCEITO DE TRAPS E ALGUMAS APLICAÇÕES EM QUÍMICA ANALÍTICA
TiO2 has been used as a white pigment and studied since the first decades of the XX century for the undesirable chalking of outdoor paintings exposed to sunlight. Since the first report of Honda and Fujishima (1972) of the water splitting by the harvesting of sunlight on a n-type single crystal TiO2 electrode, the engagement of researchers with the field has

11. Multifunctional photoprotection: corrective makeup for cutaneous dyschromias
The aim of this study was to develop and evaluate a corrective and photoprotective makeup for patients with dyschromias. An emulsion was prepared and pigment mixtures were incorporated in the formulation, producing five shades of corrective makeup: BEIGE (I, II, III), BRONZE and TAN. The sun protection factor (SPF) and UVA/UVB ratio of the corrective makeup

12. Aluminum stress tolerance in potato genotypes grown with silicon
ABSTRACT Potato cultivation is widespread around the world, being exposed to several abiotic stresses, including soils with high aluminum (Al) availability. Silicon (Si) is recognized for alleviating the stress caused by Al in various plant species. Thus, the aim of this study was to investigate the potential of Si to mitigate the oxidative stress caused by
