A poly-epsilon-caprolactone based biofilm carrier for nitrate removal from water

Nitrate removal from water has been accomplished by heterotrophic biofilms using organic carbon as a source of reducing power. To overcome the natural limitation in organic carbon in water, a poly-epsilon-caprolactone based biofilm carrier that serves simultaneously as a biofilm carrier and as a source of organic carbon was developed and tested in the present work. The feasibility of the new biofilm carrier for...

Tribological evaluation of hydrogels for artificial articular cartilage

Bacterial cellulose (BC) is a natural and biocompatible gel with unique properties, such as high water holding capacity, ultra-fine fibre network and high strength that make it an interesting material for biotribological purposes. In this work, unmodified BC pellicles were grown from Gluconacetobacter xylinus in order to be used as tribological samples against bovine articular cartilage (BAC) in the presence of...

Friction and wear behaviour of bacterial cellulose against articular cartilage

Bacterial cellulose (BC) is a natural and biocompatible material with unique properties, such as high water holding capacity, ultra-fine fibre network and high strength that makes it an attractive material for the repair of articular cartilage lesions. However, data on the tribological properties of BC is very scarce, particularly if natural articular cartilage is involved in the contact. In this work, unmodifi...

International comparisons of behavioral and emotional problems in preschool chi...

International comparisons were conducted of preschool children’s behavioral and emotional problems as reported on the Child Behavior Checklist for Ages 1½–5 by parents in 24 societies (N¼19,850). Item ratings were aggregated into scores on syndromes; Diagnostic and Statistical Manual of Mental Disorders–oriented scales; a Stress Problems scale; and Internalizing, Externalizing, and Total Problems scales. Effect...

Presence of Gardnerella vaginalis in healthy portuguese women : a pilot study

Bacterial vaginosis (BV) has an important position worldwide, as the leading vaginal disorder in women, and affects 30-50% of African women and 10-20% of White women of reproductive age. This condition although not mortal causes great discomfort and may lead to other complications such as pre-term labour or increase susceptibility for HIV infection. During BV occur a decrease of Lactobacillus spp. present in t...

Caracterização dos antecedentes psiquiátricos nos doentes com demência: relação...

Depression has been reported as the most frequent neuropsychiatric diagnostic on the clinical background of demented patients, mainly with Alzheimer dementia (AD). Several studies have showed that this relation is not occasional. In this work we present the results of the statistical analysis made on the characterization of the psychiatric background of demented patients from the memory consultation of the Brag...
