Leprosy in individuals unearthed near the Ermida de Santo André and Leprosarium...

Documentary sources refer to leprosy patients in the Portuguese territory since the first century AD, and in the Middle Ages around 70 leprosaria were established. However, prior to 2003 this historical evidence had not been confirmed by archeological findings. The excavation performed in monitoring the rehabilitation done by the Polis program in the area of the Ermida de Santo André (hermitage of Saint Andrew)...

Diversity in UV sensitivity and recovery potential among bacterioneuston and ba...

Aims: To assess the variability in UV-B (280–320 nm) sensitivity of selected bacterial isolates from the surface microlayer and underlying water of the Ria de Aveiro (Portugal) estuary and their ability to recover from previous UVinduced stress. Methods and Results: Bacterial suspensions were exposed to UV-B radiation (3Æ3 W m)2). Effects on culturability and activity were assessed from colony counts and 3H-leu...

Treponematosis in Pre-Columbian Jamaica: a biocultural approach to the human cr...

The first inhabitants of Jamaica are now generally referred to as Taínos. It is likely that they arrived in the island after about 650 AD and were extinct by the end of the 16th century. In 1968, during the exploration of a small cave in Bull Savannah, St. Elizabeth parish, Dr. James Lee found two skulls, teeth, bones, and pottery. The aim of this work is to interpret in a biocultural perspective the one craniu...

Isolation of Surfactant-Resistant Pseudomonads from the Estuarine Surface Micro...

Bioremediation efforts often rely on the application of surfactants to enhance hydrocarbon bioavailability. However, synthetic surfactants can sometimes be toxic to degrading microorganisms, thus reducing the clearance rate of the pollutant. Therefore, surfactant-resistant bacteria can be an important tool for bioremediation efforts of hydrophobic pollutants, circumventing the toxicity of synthetic surfactants ...

Evaluating seasonal dynamics of bacterial communities in marine fish aquacultur...

The increasing problem of antibiotic resistance in common pathogenic bacteria and the concern about the spreading of antibiotics in the environment bring the need to find new methods to control fish pathogens. Phage therapy represents a potential alternative to antibiotics, but its use in aquaculture requires a detailed understanding of bacterial communities, namely of fish pathogenic bacteria. Therefore, in th...

Spot Valley cave: a new inventory and survey of Jamaica’s fourth pictograph site

Spot Valley cave was located by Mr David Fletcher and was mapped by Dr James Lee in 1970. He reported that fragments of human bones and teeth were found in crevices against the walls and in the floor associated with numerous potsherds of White Marl (Meillacan) type. The collection now kept at the University of the West Indies consists of 693 potsherds and 1 reconstructed vessel as well as a small chert componen...

Trailing end-point phenotype antibiotic-sensitive strains of Candida albicans p...

Candida albicans is an opportunistic fungal pathogen that causes severe systemic infections in immunosuppressed individuals. C. albicans resistance to antifungal drugs is a severe problem in patients receiving prolonged therapy. Moreover, trailing yeast growth, which is defined as a resistant MIC after 48 h of incubation with triazole antifungal agents but a susceptible MIC after 24 h, has been noted in tests o...

Pathogenesis of apical periodontal cysts: guidelines for diagnosis in palaeopat...

Apical periodontal cysts are benign lesions developing in relation to the apices of non-vital teeth due to inflammatory response from the infective pulp. These are epithelium-lined bony cavities containing fluid. Despite being widely reported in medical/dental literature, this common condition is poorly diagnosed and documented in the archaeological literature. We aim to clarify the correct terminology, demonst...

Determinação de chumbo em álcool combustível por voltametria de redissolução an...

Um método envolvendo a pré-concentração e redissolução anódica em condições de voltametria de pulso diferencial empregando um eletrodo de pasta de carbono modificado (EPCM) com uma resina de troca iônica Amberlite IR120 foi proposto para a determinação de íons chumbo em álcool combustível. O procedimento é baseado em um pico de oxidação do analito observado em -0,53 V(vs. Ag/AgCl) em solução de HCl. As melhores...
