چکیده
The cyanobacteria Anabaena cylindrica and Synechococcus leopoliensis (= Anacystis nidulans) were grown at different levels of UV-B radiation (439, 717, 1230 and 1405 J m “2d_ l, weighted according Caldwell. 1971) for 2 days. Dry weight was hardly affected but phycocyanin content of both species decreased linearly to the level o f UV -B radiation.

Effect of UV-B radiation on photosynthetic pigments and UV-absorbing compounds of three different soybean cultivars (Glycine max L.).
The effects of UV-B radiation on the amount of chlorophyll a, b, carotenoids, flavonoids, anthocyanins, and polyphenols of three soybean cultivars was studied. After germination in the incubator, plants were put in pots of soil and during 3 weeks and irrigated with Hoagland solution every day. After 3 weeks, plants were exposed to UV-B for 20 min every day for a week. In each cultivar, UV-B red...

One of the most important functions of the skin is to protect against various stressors. Environmental stimuli such as UV and environmental pollution increase reactive oxygen species and cause wrinkles and skin aging. Skin aging is associated with decreased collagen production and decreased activity of enzymes involved in collagen structure. Moisturizing chemicals increase the skin's ability to...

Since supplemental UV-B radiation can provide a simple and economical alternative to increase phenolic compounds in plants, we evaluated the dynamic biological responses of Alo vera L. plants to different UV-B doses (10 and 30 kJ m−2 day−1). The experiment was performed on the basis of Completely Randomize Design with 4 independent replications. Under high light conditions (600 µmol m−2 s−1), U...
