Exploring the antioxidant potential of Helichrysum stoechas (L.) Moench phenoli...

The present work explores the antioxidant potential of Helichrysum stoechas (L.) Moench phenoliccompounds for cosmetic applications involving the following steps: chemical characterization, microen-capsulation and incorporation into a moisturizer. Eighteen different phenolic compounds were identifiedin flowering aerial parts (decoction and hydroalcoholic extract), being 3,5-O-dicaffeoylquinic acid andmyricetin ...

Urinothorax as an unusual type of pleural effusion - Clinical report and revisi...

BACKGROUND: Despite the fact that there are a great number of established etiologies for pleural effusion, there are grounds for believing that there are also causes from unusual pathophysiological mechanisms, seen in certain clinical contexts and from potential iatrogenic interventions. Urinothorax is such a rare type of pleural effusion as there are fewer than 70 cases reported worldwide. CLINICAL CASE: A pat...

Scientific objects in the exhibition CHIMICA

Secondary School André de Gouveia (ESAG) is frequently associated to Lyceu d’Évora from which it inherited the historical and cultural background. Lyceu d’Évora was established in 1841 after the educational reform of Passos Manuel and it was set at the Colégio do Espírito Santo, in Évora, until 1979. During that period, a physics and chemistry laboratory was created and developed at the Lyceu and it was enriche...

Orbital lymphangioma: a surgical challenge

Lymphangioma is an uncommon venolymphatic lesion with dead-end lymphatic channels, also defined as vascular hamartoma of lymphatic origin. Orbital lymphangiomas present management challenges to the ophthalmologist due to the tendency to recur locally unless it is completely excised, this is often difficult, because lymphangiomas tend to be infiltrative. The recurrence of hemorrhage and expansion can lead to vis...

Postenucleation socket syndrome: surgical repair

Introduction: A contracted eye socket is a functional and cosmetic misfortune to the patient. It makes impossible to the patient to wear an eye prosthesis, but also becomes a source of chronic infection, discharge and irritation. There are several surgical techniques to deal with the postenucleation socket syndrome. Methods: Six consecutive patients with postenucleation socket syndrome underwent reconstruction ...

Dacryocystorhinostomy: drill technique

Introduction: Dacryocystorhinostomy or DCR is a bypass procedure with an anastomosis between the lacrimal sac and the nasal mucosa via a bony ostium. It may be performed through an external skin incision or intranasally with or without endoscopic visualization. The success rates for endoscopic and external dacryocystorhinostomy vary widely (external 70-95%; endonasal 59-99%). Video: In the “classic” Dupuy-Dutem...

Endothelialization of chitosan porous conduits via immobilization of a recombin...

The present study aimed to develop a pre-endothelialized chitosan (CH) porous hollowed scaffold for application in spinal cord regenerative therapies. CH conduits with different degrees of acetylation (DA; 4% and 15%) were prepared, characterized (microstructure, porosity and water uptake) and functionalized with a recombinant fragment of human fibronectin (rhFNIII7–10). Immobilized rhFNIII7–10 was characterize...

Virtual screening of thieno[3,2-b]pyridine arylthioether (hetero)aryltriazole d...

Recently we presented a series of thieno[3,2-d]pyrimidinc ether I ,3-diaryl ureas with potent VEGFR2 inhibit ion activity. The binding mode was analyzed and the compounds showed a type-11 tyrosine kinase inhibition mode, with the thienopyrimidine moiety forming a Hydrogen Bond (H-bond) with CYS919 residue and the urea moiety forming a H-bonds with key residues G LU885 and ASP I 046 of the kinase domain. In thi...
