Circulating IgG Fragments for Gastric Cancer and Esophageal Cancer.

Blood serum of patients with gastric ( = 68) and esophageal ( = 43) cancer was assessed for proteolytic fragments of IgG. Serum samples of 20 healthy donors were used as a control. We analyzed indicators of hemostasis (prothrombin time, fibrinogen, plasminogen activity, a2-antiplasmin activity, protein C activity) in blood plasma and the level of total IgG in the blood serum.

Morfofunctional and Molecular Changes in Placenta and Peripheral Blood in Preeclampsia and Gestational Diabetes Mellitus.

Gestational diabetes mellitus (GDM) and preeclampsia (PE) are common pregnancy complications with similar risk factors. Although GDM is associated with PE, the exact mechanism underlying the association is unclear. The objective of this work was to study the morphofunctional and molecular changes in the placenta and peripheral blood in PE and GDM.

[The role of mast cells in physiological and complicated pregnancy].

Mast cells (MCs) are highly differentiated and multifunctional immune cells. The importance of TC has been established not only as mediators of allergic reactions, but also for the development of an immune response, the occurrence of certain autoimmune diseases, tissue homeostasis, the formation of immunotolerance and metastasis of malignant tumors. MCs are present in the endometrium of women in various value depending on age, the phase of the menstrual cycle, the presence of pregnancy.

[Clinical and morphological characteristics of the atypical placentation spectrum in the uterus].

Background: The concern of the global community of gynecologists and obstetricians (FIGO) regarding the increase in the number of caesarean sections has resulted in the creation of a new classification, Placenta Accreta Spectrum (PAS), which presents degrees of villus invasion into the uterine wall.

Objective: Compare the main types of atypical placentation (AP) with the stages of PAS, to supplement and unify the clinical and morphological criteria AP.

Material And Methods: Surgical material was examined from 73 women after metroplasty (=61) and hysterectomies (=12) from the regions of Russia, Moscow and the Moscow region for ingrown villi and from 10 women with a typical placenta location during the first cesarean section.

Regulation of the Placental Renin-Angiotensin-Aldosterone System in Early- and Late-Onset Preeclampsia.

Preeclampsia (PE) is one of the most dangerous complications of pregnancy, characterized by hypertension, proteinuria, and symptoms of multiple organ failure, which are detected de novo after 20 weeks of pregnancy. The renin-angiotensin-aldosterone system (RAAS) is one of the first to recognize pregnancy and is an important regulator of blood pressure. The placenta has its own RAAS, the role of which in the development of PE is not fully understood.
