Stress urinary incontinence (SUI) is a condition that causes the involuntary loss of urine when making small efforts, which seriously affects daily life of people who suffer from it. Women are more affected by this form of incontinence than men, since parity is the main risk factor. Weakening of the pelvic floor tissues is the cause of SUI, although a complete understanding of the cellular and molecular mechanisms of the pathology is still lacking.

The established therapeutic approaches (allergen avoidance, antihistamines, and corticosteroids) do not address the underlying causes of the pathology, highlighting the need for other long-term treatment options. Antigen-specific immunotherapy enables the long-term control of allergic diseases by promoting immunological tolerance to the allergen.

Factor V is a component of the prothrombinase complex responsible for accelerating conversion of prothrombin to thrombin. At the present time there are no therapeutic factor V concentrates available.

By combining drugs with different mechanisms of action, the limitations of each individual agent can be overcome, while increasing therapeutic benefit. Here, we propose employing tumor-migrating decidua-derived mesenchymal stromal cells as therapeutic agents combining antiangiogenic therapy and chemotherapy.

The placenta has unique, intrinsic features because it plays many roles during gestation: it is formed by cells from two individuals (mother and fetus), contributes to the development and growth of an allogeneic fetus, and has two independent and interacting circulatory systems. Different stem and progenitor cell types can be isolated from the different perinatal tissues making them particularly interesting candidates for use in cell therapy and regenerative medicine.

The major producers of FVIII in the adult are liver sinusoidal endothelial cells (LSECs) and in a lesser degree bone marrow-derived cells, both of which have been shown to ameliorate the bleeding phenotype in adult HA mice after transplantation. We have previously shown that cells from the foetal liver (FL) and the aorta-gonads-mesonephros (AGM) haematopoietic locations possess higher LSEC engraftment potential in newborn mice compared with adult-derived LSECs, constituting likely therapeutic targets for the treatment of HA in neonates.

Ultrasound-responsive mesoporous silica nanoparticles are coated with polyethylenimine to favor their effective uptake by decidua-derived mesenchymal stem cells. The responsive-release ability of the designed nanoparticles is confirmed, both in vial and in vivo.

Several immunomodulatory therapies are available, including interferon-β, glatiramer acetate, natalizumab, fingolimod, and mitoxantrone. Although useful to delay disease progression, they do not provide a definitive cure and are associated with some undesirable side-effects.

Two types of nanoparticles were evaluated. The nanoparticles showed negligible toxicity to the cells, a fast uptake and a long retention inside them.
View Article and Find Full Text PDFLung alveolar type II (ATII) cells are specialized in the synthesis and secretion of pulmonary surfactant, a lipid-protein complex that reduces surface tension to minimize the work of breathing. Surfactant synthesis, assembly and secretion are closely regulated and its impairment is associated with severe respiratory disorders. At present, well-established ATII cell culture models are not available.

In our centre, part of the schedule of the dedicated headache clinic (DHC) is reserved for patients referred from primary care (PC) in the form of one-stop clinics.
Aims: To analyse both the characteristics of the patients referred by PC to DHC and the suitability of the agreed referral criteria, and to compare them with the first visits due to headache in a general neurology clinic.
Background Aims: Previously, we have shown that human decidua-derived mesenchymal stromal cells (DMSC) are mesenchymal stromal cells (MSC) with a clonal differentiation capacity for the three embryonic layers. The endodermal capacity of DMSC was revealed by differentiation into pulmonary cells. In this study, we examined the hepatic differentiation of DMSC.

Methods: Primary culture of rat HSCs were plated on fibronectin-uncoated or coated culture wells, and grown in the presence of 0.2% or 20% fetal calf serum.
Interleukin-6 (IL-6) increases metalloproteinase-13 (MMP-13) gene expression by increasing phosphorylated c-Jun and by inhibiting serine/threonine phosphatase-2A (PP2A) activity. We investigated the mechanisms by which IL-6 induces c-Jun phosphorylation and PP2A inactivation in Rat-1 fibroblasts. We show that IL-6 increased MMP-13 mRNA, phosphorylated c-Jun, and activator protein 1 (AP1) binding activity without increasing c-Jun-N-terminal kinase (JNK) activity.

Simultaneously, the transcript levels of two nuclear-encoded glycolytic enzymes, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphofructokinase, were increased. These changes were associated with decreased protein levels of the ATPase subunit a (encoded by the mitochondrial ATPase 6 gene) and cytochrome c oxidase subunit II, and increased protein levels of phosphofructokinase.

This population is mainly represented by Brazilians, Chileans, Peruvians and Argentines. However, since 1984, Chileans and Argentines have begun a [return] movement to their countries.
