Autoeficácia docente e indisciplina: Perceções de professores do 3.º Ciclo do E...

Um clima escolar positivo prediz positivamente a autoeficácia dos professores. Este artigo reporta os resultados de um estudo que explorou as relações entre as crenças de autoeficácia de professores portugueses para gerir a indisciplina em sala aula, o clima escolar e clima de sala de aula. Participaram 400 professores do 3.º ciclo do ensino básico, os quais responderam a três questionários que avaliam as suas ...

Fuel cells operating as an immunosensor for cancer biomarker screening

This work presents the first integration of antibodies into one of the electrodes of a passive direct methanol fuel cell (DMFC) to create an autonomous immunosensor for cancer antigen 15–3 (CA15-3). The anode of the fuel cell was first made of carbon cloth with carbon black, platinum and ruthenium nanoparticles and then modified with anti-CA15-3, while the cathode was made of carbon cloth with carbon black and ...

A passive direct methanol fuel cell as transducer of an electrochemical sensor,...

This work describes an electrochemical sensor with a biomimetic plastic antibody film for carcinoembryonic antigen (CEA, an important biomarker in colorectal cancer), integrated in the electrical circuit of a direct methanol fuel cell (DMFC), working in passive mode and used herein as power supply and signal transducer. In detail, the sensing layer for CEA consisted of a Fluorine-doped Tin Oxide (FTO) conductiv...

Efeito do treino do músculo transverso abdominal associado ao dos músculos do p...

Objetivo: Determinar o efeito do trabalho do músculo transverso abdominal associado ao trabalho dos músculos do pavimento pélvico na incontinência urinária (IU). Metodologia: Pesquisa computadorizada nas bases de dados Pubmed/Medline e Web of Science, incluindo estudos randomizados controlados. A qualidade metodológica dos estudos foi avaliada através da Physiotherapy Evidence Database scoring (PEDro) Scale. Re...

Development of a biosensor for a biomarker CA15-3 in breast cancer by electropo...

Breast cancer is a disease that affects millions of people in the world and a constant search for the reduction of its incidence is necessary. If a global cure is not possible, methods must be developed to allow an early diagnosis, thereby reducing the level of disease progression. In the present study, we aim to obtain a molecularly-imprinted polymer (MIP) for the detection of a breast cancer biomarker (CA15-3...
