Sexual activity during pregnancy is determined by emotional, psychosocial, hormonal, and anatomical factors varies trimesters. This work aimed to establish women's sexual each trimester of pregnancy. A total 624 women were included in the study filled questionnaire three times, once The first part survey questions about socio-demographic characteristics, obstetric history, medical details a given second was Polish version female function index (FSFI) questionnaire. Comparison mean scores for...

ABC transporters, P-gp, MDR3, BCRP and MRP1, can bind both endo- exogenous ligands. The latter include immunosuppressive, anticancer sedative, anticonvulsant, antiparasitic cardiovascular drugs, as well HIV protease inhibitors antibiotics. Protein transporters are also involved in tissue distribution of orally administered medicines combination therapy for gestational diabetes mellitus (GDM) could be used during GDM treatment. depends on transporter specificity its expression subcellular...

RCAS1 is involved in generating the suppressive profile of tumor microenvironment that helps cancer cells evade immune surveillance. The status surrounding nest may affect both progression and development metastases. In cases ovarian cancer, a large number patients do not respond to applied therapy. patient's response therapy directly linked intensity its profile. We analyzed immunoreactivity on present with disease; these included macrophages carcinoma-associated fibroblasts. Later we...

Acceleration and deceleration patterns in fetal heart rate (FHR) are widely used as an assessment of condition. The paper presents a method for evaluation expert's interpretation the FIGO definition acceleration FHR trace. Two indices describing disagreement between monitoring system experts have been defined. results obtained indicate essential differences procedure acceleration/deceleration recognition by computerized human expert.

<i>Introduction:</i>Scar deciduosis provides a research model that enables us to assess the impact of decidua on activity and quality immune cells infiltrating this scar tissue. This unique allows examine these processes under conditions excluding placental which, along with decidual cells, control physiological conditions. RCAS1 is protein responsible for suppression cytotoxic response during gestation. The present study evaluates immunoreactivity level respect cell status in...

Fetal monitoring based on the analysis of fetal heart rate (FHR) signal is most common method biophysical assessment condition during pregnancy and labor Visual FHR signals presents a challenge due to complex shape waveforms. Therefore, computer-aided systems provide number parameters that are result quantitative registered signals. These basis for qualitative condition. The guidelines interpretation provided by FIGO commonly used in clinical practice. On their weighted fuzzy scoring system...
