Nitric oxide is involved in nano-titanium dioxide-induced activation of antioxidant defense system and accumulation of osmolytes under water-deficit stress in Vicia faba L.

Background: Faba beans (Vicia faba L.) are important grain legumes but, as with many crops, these are also susceptible to water deficit. The aim of this study was to evaluate the yield components of twenty faba bean genotypes grown under water deficit.Methods: Three water treatments were applied, 25%, 50% and 100% of field capacity. A split-plot arrangement in a randomized complete block design with three replicates was used.Result: The faba genotypes Gazira2, Kamline, L4, Cairo7 and Giza402 reached flowering earlier than other genotypes through stress-escape mechanisms. Genotypes L4, Gazira1, Kamline, X.735 and Gazira2 had the highest seed yield under water-deficit conditions. Genotypes L4, X.735, 989/309/95, Kamline and Gazira1 exhibited the highest levels of biological yield. Finally, the genotypes Kamline and L.4 had higher yields and yield components under water-deficit stress. Consequently, they should be considered for use in breeding programs aimed at developing new cultivars that are better adapted to harsh environmental conditions.

The Brain

The aim of the study was to determine the adaptogenic effect of the extract from the roots of Phlojodicarpus sibiricus during ischemic influence on the left hemisphere of the brain. Experiments were conducted on Wistar rats of both sexes weighing 200-220 g. Unilateral cerebral ischemia was induced by permanent occlusion of the left common carotid artery under ether anesthesia. Adaptogenic anti-ischemic effect of Ph. sibiricus was determined by the number of desquamated endotheliocytes, nitrogen oxide metabolites – nitrites in the blood, by the content of lipid peroxidation products – malondialdehyde (MDA) and the activity of the antioxidant defense system in the brain tissue. It is established that Ph. sibiricus has an anti-ischemic effect, reduces the number of endotheliocytes desquamated, increases the level of nitric oxide in the blood (p ≤ 0.05), stimulates SOD and catalase activity, reducing the intensity of lipid peroxidation and the accumulation of MDA in the brain during ischemic exposure (p ≤ 0.05). Preventive administration of Ph. sibiricus extract has an adaptogenic effect in unilateral cerebral ischemia, which consists in reducing desquamated endotheliocytes, increasing the production of nitric oxide by endothelium, increasing the antioxidant defense system and reducing the intensity of oxidative reactions in the brain. Adaptogenic effect of Ph. sibiricus extract is caused by endothelium protective and antioxidant effects.
