Experience of using time lapse microscopy in the IVF program in patients with good ovarian reserve.

The aim of this study is to evaluate the outcomes of single embryo transfer in patients with good ovarian reserve in the IVF program using time-lapse microscopy. This is a retrospective cohort study in a private IVF center in Russia. Comparison was done between 90 IVF cycles using time-lapse (study group) and 113 IVF cycles using standard culture (control group).

polymorphism frequency in Russian patients in Central Russia and Siberia with acute coronary syndrome.

Purpose: The aim of this study is to investigate the frequency of allelic variants, associated with poor response to clopidogrel, and , associated with excessive response to clopidogrel, in patients with acute coronary syndrome (ACS) from Siberia and Moscow regions of Russia.

Patients And Methods: The study included 512 ACS patients who were subsequently treated with coronary arterial stenting. The subjects assigned were from the cities of Central (Novosibirsk, Kemerovo), Eastern (Irkutsk), Northern (Surgut) Siberia regions and from Moscow region.

[Development of hematopoietic tissue in Rana temporaria L].

Embryogenesis of the hemopoietic tissue was histologically studied in Rana temporaria at successive developmental stages, beginning from neurula and up to the end of metamorphosis. Primary foci of hemopoiesis (yolk sac, pronephros, hepatic diverticulum) were also studied radioautographically. Histological description of the hemopoietic tissue in R.

[Differentiation of hematopoietic cells in explants of embryonal organs of Rana temporaria L].

The potencies of isolated embryonic hemopoietic organs (pronephros and liver) of Rana temporaria L. to the formation of the foci of hemopoiesis were studied. The pronephros and liver rudiments were explanted at the early developmental stages (late neurula and early tail bud) and cultivated in vivo in the diffusion chambers.
