Article Synopsis
- Lupus erythematosus (LE) is a group of autoimmune diseases that can affect the skin, and it's hard for AI to tell the different types apart.
- Researchers created a new deep learning system to help doctors correctly identify these types of LE and other similar skin conditions using many images and data collected from multiple locations in China.
- The new system significantly improved the accuracy of doctors in diagnosing LE, raising their success rate from about 67% to over 81%, showing how helpful AI can be in medicine.
Baicalein, one of the four major flavanoids extracted from the root of Scutellaria baicalensis, has been shown to exert chemopreventive effect against several cancers, including skin cancer. However, the precise mechanisms remain to be elucidated. In the present study, we investigated the chemopreventive activity of baicalein against 7,12-dimethylbenz[a]anthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA)-mediated skin tumorigenesis in C57BL/6 mice.

Methods: Relevant randomized controlled trials (RCTs) were identified by systematic literature searches in MEDLINE, OVID, EMBASE, Cochrane Library, and the metaRegister of Controlled Trials. The efficacy outcomes and adverse effects of included RCTs were critically assessed.
[Study on the conversion of acrylic C=C double bonds during dark reaction after UV curing using infrared spectroscopy].

Infrared spectroscopy was used to determine 1,648-1,589 cm(-1) characteristic absorption peak area so as to study the conversation of acrylic C=C double bonds after UV curing. The effects of phototinitiators, active diluents and UV curing resins on the conversion of C=C double bonds were also investigated. The results showed that 40%-85% of C=C double bonds were conversed during dark reaction after 45 s UV curing.

March 2006
A new light emitting material, salicylaldehyde anil zinc (SAZ), was synthesized. It can form high quality nano-scale amorphous thin films on clean glass substrates by vacuum evaporation. Its structure, crystallization, thermal stability, and optical property were investigated by IR spectra, DTA-TG analysis, XRD spectra, UV-Vis spectra, and fluorescence spectra.
