Hydrogen Sulfide Alleviates Anxiety, Motor, and Cognitive Dysfunctions in Rats with Maternal Hyperhomocysteinemia via Mitigation of Oxidative Stress.

Hydrogen sulfide (HS) is endogenously produced from sulfur containing amino acids, including homocysteine and exerts neuroprotective effects. An increase of homocysteine during pregnancy impairs fetal growth and development of the offspring due to severe oxidative stress. We analyzed the effects of the HS donor-sodium hydrosulfide (NaHS) administered to female rats with hyperhomocysteinemia (hHcy) on behavioral impairments and levels of oxidative stress of their offspring.

[Morphofunctional characteristics of malignant thyroid gland tumors in children from various regions of the Ukraine, who have been victims of of the Chernobyl nuclear power plant accident].

Thyroid cancers in children from the affected areas of Ukraine were investigated by means of light (33 cases) and electron (20 cases) microscopy. Statistical data from 25 regions of Ukraine have been analyzed concerning thyroid cancer in patients aged up to 18 years for the period 1981-1990. There is an increase in the number of thyroid cancers in the children of Ukraine from 0.
