Expression of OSF-2 has been also related to the progression and drug resistance of different tumors.

Pharmacological Effect of Quercetin in Hypertension and Its Potential Application in Pregnancy-Induced Hypertension: Review of , , and Clinical Studies.

Since improving maternal and child health is a public health priority worldwide, the main aim of treatment of hypertension in pregnant women is to prevent complications during pregnancy, labor, and postpartum. In consequence, much attention is paid to the use of antihypertensive drugs that can be used safely during pregnancy. Several side effects of methyldopa, which is currently the most commonly used antihypertensive drug in pregnant women, mean that the search for an effective and safe alternative still continues.

[Influence of smoking on pregnency course and fetal development].

Smoking is a significant factor which affects not only reproduction and the process of pregnancy but also the offspring. Endangering for tobacco smoke and nicotine either passive or active has an important influence for shortening the time of pregnancy, the weight of the newborn and the Placenta. The occurrence of complications connected with smoking is probably correlated with the amount of cigarettes smoked per day.
