Ischemia-Modified Albumin and Antioxidant Capacity of Blood Serum in Normal Pregnancy and Preeclampsia.

A comparative study of oxidative stress markers (ischemia-modified albumin (IMA) and the blood serum antioxidant capacity) in normal pregnancy and preeclampsia was carried out. The IMA level and blood serum antioxidant capacity increased in the following order: healthy non-pregnant women→healthy pregnant women→patients with moderate preeclampsia→patients with severe preeclampsia (p<0.001).

Nitrogen Oxide (NO) in the Pathogenesis of Preeclampsia.

The concentrations of nitric oxide (NO) donors in the plasma of pregnant women with preeclampsia is several times higher than in healthy pregnant women. Antihypertensive drugs acting not through the NO-mediated mechanisms normalized BP in some women with preeclampsia, but did not significantly reduce the levels of NO donors in the plasma. It appears that preeclampsia is associated with insufficient NO availability for the targets, rather than low intensity of NO synthesis.

Measurement of the Pion Form Factor with CMD-3 Detector and Its Implication to the Hadronic Contribution to Muon (g-2).

The cross section of the process e^{+}e^{-}→π^{+}π^{-} has been measured in the center-of-mass energy range from 0.32 to 1.2 GeV with the CMD-3 detector at the electron-positron collider VEPP-2000.

DNIC is a Structure Providing Specificity of Physiological Effects of NO.

Metabolism of nitric oxide (NO) donors: dinitrosyl iron complexes (DNIC), nitrosothiols (RSNO), and nitroprusside was studied on a chick embryo model. The obtained results give reason to assume that DNIC constituting the main pool of nitroso compounds in the vast majority of tissues are NO donors immediately interacting with the physiological target of NO, and other NO donors can perform this function after their transformation into DNIC. NO is released from DNIC not spontaneously, but under a joint influence of a factor destroying the complex and a target having chemical affinity for NO.
