Vascular development is dependent on various growth factors and certain modifiers critical for providing arterial or venous identity, interaction with the surrounding stroma and tissues, hierarchic network formation, and recruitment of pericytes. Notch receptors and ligands (Jagged and Delta-like) play a critical role in this process in addition to VEGF.(More)
Neo-blood vessel growth (angiogenesis), which may involve the activation of pre-existing endothelial cells (EC) and/or the recruitment of bone marrow-derived vascular precursor cells (BM-VPC), is essential for tumor growth. Molecularly, besides the well established roles for Vascular endothelial growth factor (VEGF), recent findings show the Notch(More)
PURPOSE To compare the efficacy of 3 different artificial tears (AT) acting primarily in one of the 3 tear film layers (Tears Again®, lipidic; Opticol®, aqueous; Optive®, mucin) in recovering the tear film changes in patients with dry eye symptoms due to external causes. METHODS A total of 27 patients, with dry eye symptoms associated with extra hours of(More)
The Hymenodictyon genus comprises 22 species. Of these, 11 are endemic to Madagascar, 4 to Asia and 7 to Tropical Africa. Hymenodictyon floribundum B.L. Rob. (Rubiaceae), endemic to Tropical Africa, is a small tree that grows in the mountains of the Huíla province and its traditional name is NDambi Yov`olwi, (omu)Lia-tyimeme. Its trunk bark is used in(More)
Recurrent tracheoesophageal fistula in children is a challenging issue, associated to high morbidity and mortality, due to major scarring and inflammatory changes resulting from previous interventions and the disease itself. Most cases require surgical treatment, but the complexity of the situation may, sometimes, prevent the traditional approach by(More)
A 6-month-old girl with Beckwith-Wiedemann syndrome, multiple haemangiomas (axillary, laryngeal, pulmonary and hepatic) and diaphragmatic eventration was reported. All tumours responded to treatment with propranolol. The surgical correction of diaphragmatic eventration was crucial to a better outcome.
