A  -mercaptoethanol-modified enzyme-linked immunosorbent assay for diagnosis of...

Two immunoglobulin G enzyme-linked immunosorbent assay (ELISA) versions using whole promastigotes of Leishmania infantum (syn. Leishmania chagasi) treated either with β-mercaptoethanol (β-ME-ELISA) or trypsin (TRYP-ELISA) as antigens were developed for the diagnosis of canine visceral leishmaniasis (CVL). By comparison with the direct agglutination test (DAT; 100%, 31/31; 95% confidence interval [CI]: 86.3–100%...

Phenolic composition and antioxidant potential of Vitis vinífera leaves of six ...

In the present work it was intended to study the phenolic composition and antioxidant potential of Vitis vinifera leaves of six varieties: white – Carrega Branco, Chardonnay and Viosinho, and red – Bastardo, Tinta Gorda and Touriga Francesa. All varieties were harvested in the NE of Portugal (Trás-os-Montes region). The phenolic composition of aqueous extracts was determined by HPLC-DAD and the antioxidant pote...

Karapandzic flap and Bernard-Burrow-Webster flap for reconstruction of the lowe...

Squamous cell carcinoma is the most common malignant neoplasm of the lips, and in about 90% of cases it is located on the lower lip due to higher cumulative exposure to ultraviolet radiation. The authors present two surgical techniques for reconstruction of large lower lip defects, resulting from surgical excision of tumors, exemplifying and comparing them with two clinical cases.

Linear psoriasis - a case report.

A 56-year-old woman presented with a 3-month history of erythematous plaques covered by scales and limited to the right side of her body. The plaques were arranged along Blaschko's lines with a marked mid-line cutoff. The histopathologic analysis of a skin biopsy in conjunction with the anamnesis allowed the diagnosis of linear psoriasis. Our patient showed a good clinical response to antipsoriatic treatment.

Patch testing in fixed drug eruptions: a 20-year review.

BACKGROUND: The fixed drug eruption is a common adverse drug reaction. Clear identification of the culprit drug is not always possible in the clinical setting, and oral rechallenge may induce new lesions or severe reactions. OBJECTIVES: The main purpose of this study was to evaluate the diagnostic value of patch testing in establishing an aetiological diagnosis in fixed drug eruptions. METHOD: A retrospective...

Apresenta-se o estudo das descontinuidades e das potenciais situações de instabilidade de uma pedreira de calcário ornamental que se localiza nas imediações de Valinho de Fátima (freguesia de Fátima). Definiram-se três famílias principais de descontinuidades, bem como as suas principais características: orientação, espaçamento, persistência, abertura, material de preenchimento, rugosidade, presença da água, índ...

CARD15 mutations and colorectal cancer in a South European country

PURPOSE: CARD15 mutations are associated with higher susceptibility to Crohn's disease (CD) and longstanding colonic CD increases the risk of developing colorectal cancer (CRC). The relation between these mutations and sporadic CRC remains controversial. The aim of this study was to assess whether germline and/or somatic CARD15 mutations are risk factors for sporadic CRC in Portugal and whether there are genoty...

CARD15 Mutations and Perianal Fistulating Crohn’s Disease: Correlation and Pred...

BACKGROUND: CARD15 mutations alter bowel immunity and increase susceptibility to Crohn's disease (CD). However, the relation between these mutations and Crohn's perianal fistulas has not been fully clarified. AIMS: To assess whether CARD15 mutations are associated with risk of developing Crohn's perianal fistulas and whether these mutations are predictors of the response of perianal fistulas to antibiotics. M...
