Silicon-Mitigated Effect on Zinc-Induced Stress Conditions: Epigenetic, Morphological, and Physiological Screening of Barley Plants.

Plants are increasingly exposed to stress-induced factors, including heavy metals. Zinc, although it is a microelement, at high concentrations can be phytotoxic to plants by limiting their growth and development. The presented research confirmed the inhibition effect of Zn on morphological and physiological parameters in barley plants.

Foliar Application of Silicon Influences the Physiological and Epigenetic Responses of Wheat Grown Under Salt Stress.

Soil salinity is considered a serious problem that limits agricultural productivity. Currently, solutions are being sought to mitigate the negative impact of salt on economically important crops. The aim of the study was to evaluate the effect of foliar application of silicon (Si) on the physiological and epigenetic responses of wheat grown under salt stress conditions.

Physiological and Epigenetic Reaction of Barley ( L.) to the Foliar Application of Silicon under Soil Salinity Conditions.

Soil salinity is an important environmental factor affecting physiological processes in plants. It is possible to limit the negative effects of salt through the exogenous application of microelements. Silicon (Si) is widely recognized as an element improving plant resistance to abiotic and biotic stresses.

Effect of chloroquine wash-out period of photosensitizers in the skin and selected organs in rats.

In the last decade, photodynamic therapy has become an alternative method for the diagnosis and therapy of tumors. In human medicine hematoporphyrin derivatives, sulfonated hydrophilic meso-tetraphenylporphyrin (TPPS4) and an oligomer of hematoporphyrin (Photosan 3), are widely used. Chloroquine is used for the treatment of porphyria cutanea tarda for its power to release porphyrins from the liver tissue.
