: The aim of this study was to demonstrate the effects of using a preparation containing kojic acid on skin hyperpigmentation using hyperspectral imaging, which enables a quantitative assessment of the effect of the preparation used on the reduction of skin discoloration. : Preliminary studies were carried out on 12 patients with post-acne skin. A hyperspectral camera with a spectral range of 400-1000 nm was used to image skin hyperpigmentation before and after the application of 3% kojic acid. Hyperspectral profiles were analyzed, and image analysis and processing methods were applied. : Studies performed using a hyperspectral camera have shown that kojic acid reduces skin discoloration by increasing skin brightness in 75% of patients tested, reducing skin contrast in approximately 83% and increasing skin homogeneity in approximately 67% of patients.

In this study, the structure of a new boron compound obtained using 3-methoxy catechol and 4-methoxy phenyl boronic acid was characterized by H, C NMR, LC-MS-IT-TOF, UV-Vis and FTIR spectroscopy. The antioxidant activities of the newly synthesized compound were evaluated by DPPH free radical scavenging, ABTS quation radical scavenging and CUPRAC copper reducing capacity methods. Anticholinesterase activities were determined by acetylcholinesterase and butyrylcholinesterase enzyme inhibitor assays.

Translation initiation, which involves numerous protein factors and coordinated control steps, represents the most complicated process during eukaryotic translation. However, the roles of eukaryotic translation initiation factor (eIF) in filamentous fungi are not well clarified. In this study, we investigated the function of eIF2Bα in Aspergillus oryzae, an industrially important filamentous fungus.
