Among many antioxidants that are used for the repairing of oxidative stress induced skin damages, we identified enriched astaxanthin extract (EAE) from Haematococcus pluvialis as a viable ingredient. EAE was extracted red microalgae through supercritical fluid carbon dioxide extraction. To compare effectiveness, wastreated on human dermal fibroblasts with other components, phorbol 12-myristate 13-acetate (PMA), and doxycycline. With sirius staining quantitative real-time polymerase chain...
Metal-oxide-semiconductor field-effect transistors (MOSFETs) based on wide-band-gap semiconductors have garnered significant attention for their potential in high-performance and energy-efficient electronic devices. In this study, we explore the low-temperature growth, characterization, performance of ZnGa2O4 film MOSFETs sapphire substrates through utilization radio frequency (RF) magnetron sputtering. The characteristics films were meticulously investigated at various annealing...
β-Ga2O3-based MOSFETs hold significant promise for high-power device applications due to their wide band gap and high breakdown voltage. However, the direct integration of β-Ga2O3 on silicon substrates is challenged by lattice thermal expansion mismatches, which degrade performance. This work explores use an aluminum nitride (AlN) buffer layer mitigate these issues, offering improved structural quality enhanced electrical We demonstrate growth β-Ga2O3/AlN/Si films using metal–organic...
There are many compounds used to treat cancer, but still, only 20% of proposed anticancer agents have been commercialized after clinical trials due serious side effects and unsatisfactory results. To screen potential drugs precisely quickly, this study develops a flexible bioimpedance sensor. The sensor positively detects the half maximal inhibitory concentration (IC50) in real time by analyzing phase angle changes during cell mortality. best results achieved using probe separation A12B34 at...
In this research we utilized extracts from two different nature products, Achatina fulica and Heimiella retispora, to enhance skin moisturizing abilities, anti-oxidative properties, cell proliferations. It was observed that polysaccharides with effects by chelating metal ions reduced oxidative stress further blocked the formation of reactive oxygen species syntheses. To detect whether there a similar effect within cellular mechanism, flow cytometry applied for sensing level it found both...
Intracellular reactive apoptosis and oxygen species (ROS) play a crucial role in ultraviolet- (UV-) induced inflammation aging reaction human dermal tissues. This study determines the mechanism by which Haematococcus pluvialis extracts (HPE) purified astaxanthin (HPA) to promote skin regeneration injured tissue vitro vivo . The results show that HPE HPA decrease DNA damage secretion of collagen from normal fibroblast cell line (Hs68) dose-dependent manner. UV irradiation reduce oxidative...
Melanin uncontrollable accumulation is a serious social problem to not only women, but also men, and causes pigment over-expression disorders such as freckles, melasma or pigmented acne scars. The synergism used widely in medication, the effectiveness makes drug applications more valuable. Within this experiment, three well-known compounds were chosen: kojic acid, 1-phenyl-2-thiourea (PTU) arbutin, they combined individually with our substance linderanolide B, which purified from Cinnamomum...
In the melanin synthesis process, oxidative reactions play an essential role, and it is a good strategy to inhibit production by reducing stress. Fullerene its derivatives, or complexes, were considered as strong free-radical scavengers, we further applied multilayered sp2 nanocarbons discover inhibitory mechanisms. present study, used novel nanomaterials, such multiwalled carbon nanotubes (MWCNTs), short-type MWCNTs, graphene oxide nanoribbons (GONRs), GONRs, anti-oxidative agents regulate...
