AIMS To investigate the therapeutic effects of bone marrow-derived mesenchymal stem cells (BMSCs) transplantation on intrauterine adhesions (IUA). METHODS BMSCs were isolated and labeled by green fluorescence protein. IUA model was established by mechanical injury. 48 rats were randomly divided into control, IUA model, BMSCs vein injection and BMSCs intrauterine injection groups (n=12 in each...

The fusion of synaptic vesicles (SVs) with the plasma membrane of the active zone (AZ) upon arrival of an action potential (AP) at the presynaptic compartment is a tightly regulated probabilistic process crucial for information transfer. The probability of a SV to release its transmitter content in response to an AP, termed release probability (Pr), is highly diverse both at the level of entire...

Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS) is a disease pertained to the human immune system. Given its crucial role in viral replication, HIV-1 protease (HIV-1 PR) is a prime therapeutic target in AIDS therapy. In this regard, the dynamic aspects of ligand-enzyme interactions may indicate an important role of conformational variability in HIV-1 PR in...

Mammary epithelium contains lineage-limited progenitors that give rise to cells that form distinct morphological structures, ducts vs. lobules, depending on the endocrine status of the female. Progesterone signaling through progesterone receptor (PR) is essential for lobulo-alveolar development that accompanies pregnancy, but not for ductal growth accompanying puberty. PR exists in two molecula...

Although non-genomic steroid receptor pathways have been studied over the past decade, little is known about the direct gene expression changes that take place as a consequence of their activation. Progesterone controls proliferation of rat endometrial stromal cells during the peri-implantation phase of pregnancy. We showed that picomolar concentration of progestin R5020 mimics this control in ...

Objective Objective: Gelatinases degrade extracellular matrix (ECM) components to make physiological remodeling and contribute to pathological tissue destruction in endometriosis. It is known that gelatinases’ function is resistant to suppression by progesterone in endometriosis. The ability of progesterone to impact gene expression depends on the progesterone receptor-A/-B (PR-A/PR-B) ratio. A...

2. C (H, E, B) is a function of the values Pr (X | B) and Pr (Y | Z ∩B) assume on the at most 16 truth-functional combinations X, Y, Z of E and H . 3a. If Pr (E | H ∩B) < Pr (F | H ∩B) and Pr (E | B) = Pr (F | B), then C (H, E, B) ≤ C (H, F, B). 3b. If Pr (E | H ∩B) = Pr (F | H ∩B) and Pr (E | B) < Pr (F | B), then C (H, E, B) ≥ C (H, F, B). 4a. C (H, E ∩ F, B)−C (H, E ∩G, B) is determined by C...

Obesity is a prominent risk factor for endometrial cancer (EC) and can impede on surgical and hormonal treatments. Markers of EC, estrogen receptor (ER), progesterone receptor (PR), phospho(Ser473)-AKT (pAKT) and 14-3-3 sigma (14-3-3σ) were measured in EC tissues in both the tumor and stroma and grouped by body mass index (BMI). Immunohistochemical scoring of 82 cases of Type 1 and Type II EC t...

This study has examined endometrial tissue in 14 normal women prior to insertion of a levonorgestrel-releasing intrauterine system (LNG-IUS) and thereafter longitudinally for up to 12 months post-insertion. The specific endpoints examined by immunohistochemistry were progesterone receptor (PR) subtypes A + B, oestrogen receptor (ER) and prostaglandin dehydrogenase (PGDH). Two antiprogesterone r...
