Oxidative stress after birth led us to localize reactive oxygen and nitrogen species (RONS) production in the developing rat brain. Brains were assessed a day prenatally and on postnatal days 1, 2, 4, 8, 14, 30, and 60. Oxidation of dihydroethidium detected superoxide; 6-carboxy-2',7'-dichlorodihydrofluorescein diacetate revealed hydrogen peroxide; immunohistochemical proof of nitrotyrosine and...

Sowing the seeds: the growth of Au and Ag(2)S nanoparticles at distinct positions on CdSe-seeded CdS heterostructured nanorods can be precisely controlled by variations in the concentration of the Au and Ag precursors, respectively. The ability to direct growth on the nanorods can lead to "Janus-type" structures where Au is located at the more reactive end of the nanorod, whilst Ag(2)S is locat...

In article number 2202707, Kwang-Un Jeong and co-workers present chiroptical smart paints using cyanostilbene-based reactive mesogens. The helical nanostructures in the developed paint are precisely controlled fixed by UV light subsequent blue irradiation. Corresponding properties investigated detail. Furthermore, advanced optical information storages encryptions successfully demonstrated propo...

Thiopurine and its derivatives, including azathioprine (AZA), 6mercaptopurine (6-MP), and 6-thioguanine (6-TG) have been used as pro-drugs in cancer treatment and inflammatory bowel disease. However, unlike canonical DNA and RNA bases that mainly absorb UVC (100-280 nm) and UVB (280-320 nm) light, thiopurine bases are strong UVA (320-400 nm, covering 90% solar UV irradiation) chromophores and s...
