Nodular malignant melanoma. Or maybe not?

Bullous pemphigoid and comorbidities: a case-control study in Portuguese patients

BACKGROUND: Although rare, bullous pemphigoid (BP) is the most common autoimmune blistering disease. Recent studies have shown that patients with bullous pemphigoid are more likely to have neurological and psychiatric diseases, particularly prior to the diagnosis of bullous pemphigoid. OBJECTIVE: The aims were: (i) to evaluate the demographic and clinical features of bullous pemphigoid from a database of patien...

Contact allergy to local anaesthetics–value of patch testing with a caine mix i...

BACKGROUND: Contact allergy to local anaesthetics is relatively common. Patch testing with benzocaine in the European baseline series is recommended for diagnosis, even though a caine mix has been previously suggested to be superior. OBJECTIVES: To assess the frequency and patterns of contact allergy to local anaesthetics by using a caine mix (benzocaine, tetracaine, and cinchocaine) in the baseline series, and...

Avaliação da técnica de arteriografia renal guiada por fluoroscopia em suínos

The fluoroscopy-guided renal arteriography was evaluated in order to be used as an auxiliary method in investigations and as a way to experimentally induce kidney diseases in swine. The technique was effective to obtain sharp images as well as to determine the area of renal irrigation. Despite its easiness, trained professionals are required to perform it.

Multiple glomus tumors and segmental neurofibromatosis: there are no coincidences

Segmental neurofibromatosis is a rare subtype of neurofibromatosis type 1 (NF1). Glomus tumors are uncommon benign tumors. The authors report the association between these two rare conditions, not yet reported.

Valores da pressão arterial em cães pelos métodos oscilométrico e Doppler vascular

Foram comparados dois métodos não-invasivos de medida da pressão arterial, o Doppler vascular e o oscilométrico, com o objetivo de estabelecer parâmetros que possam auxiliar no diagnóstico seguro da hipertensão arterial. Para tal, foram utilizados 45 cães, machos e fêmeas, distribuídos em três grupos de acordo com o peso, pequeno, médio e grande porte. Em cada animal, procedeu-se a mensuração por meio do Dopple...

Non-newtonian flow and pressure drop of pineapple juice in a plate heat exchanger

The study of non-Newtonian flow in plate heat exchangers (PHEs) is of great importance for the food industry. The objective of this work was to study the pressure drop of pineapple juice in a PHE with 50º chevron plates. Density and flow properties of pineapple juice were determined and correlated with temperature (17.4 < T < 85.8ºC) and soluble solids content (11.0 < Xs < 52.4 ºBrix). The Ostwald-de Waele (pow...

Processamento e caracterização morfológica do compósito Al2O3-YAG aditivado com...

O compósito Al2O3-YAG possui alta resistência a fluência em elevadas temperaturas, o que permite vislumbrar aplicações no campo da engenharia aeronáutica e espacial, tais como motores a jato e turbinas a gás de alto desempenho. Este compósito também apresenta algumas propriedades favoráveis a seu emprego na área de blindagem balísticas, como por exemplo elevada dureza e alta resistência à abrasão. Nesse estudo ...

Linkage disequilibrium and diversity for three genomic regions in Azoreans and ...

Studies on linkage disequilibrium (LD) across the genome and populations have been used in recent years with the main objective of improving gene mapping of complex traits. Here, we characterize the patterns of genetic diversity of HLA loci and evaluate LD (D') extent in three genomic regions: Xq13.3, NRY and HLA. In addition, we examine the distribution of DXS1225-DXS8082 haplotype diversity in Azoreans and ma...

ELEVATION ON BOINLING POINT OF COFFE EXTRACT

The rise in boiling point of coffee extract was experimentally measured at soluble solids concentrations in the range of 9.2 to 52.4ºBrix and pressures between 5.8 × 10³ and 9.4 × 10(4) Pa (abs.). Different approaches to representing experimental data, including the Dühring's rule, the Antoine equation and empirical models proposed in the literature were tested. In the range of 9.2 to 16.2ºBrix, the rise in boi...
