The Stress Response to Surgery and Postoperative Delirium: Evidence of Hypothal...
Cerejeira, J; Batista, P; Nogueira, V; Vaz-Serra, A; Mukaetova-Ladinska, EBIntroduction: The aim of this study is to determine whether postoperative delirium is associated with dysregulation of hypothalamic—pituitary—adrenal and growth hormone/insulin-like growth factor 1 (GH/IGF-1) responses following acute systemic inflammation. Methods: Plasma levels of cortisol, IGF-1, C-reactive protein, interleukin (IL)-6, IL-8, and IL-10 were measured before and after surgery in 101 patients 6...
Novel methodology based on biomimetic superhydrophobic substrates to immobilize...
Lima, A. C.; Batista, P.; Valente, T.; Silva, A. S.; Correia, I. J.; Mano, J. F.Cell-based therapies for regenerative medicine have been characterized by the low retention and integration of injected cells into host structures. Cell immobilization in hydrogels for target cell delivery has been developed to circumvent this issue. In this work mesenchymal stem cells isolated from Wistar rats bone marrow (rMSCs) were immobilized in alginate beads fabricated using an innovative approach involv...

Lima, A. C.; Batista, P.; Valente, T.; Silva, A. S.; Correia, I. J.; Mano, J. F.The low retention/integration of injected cells by host structures represents an important challenge in cell based therapies for regenerative medicine purposes. Cell immobilization in hydrogels for target cell delivery has been developed to circumvent this issue. However, the existing immobilization methodologies sometimes have several steps under wet conditions and present some drawbacks, including poor encaps...
Low preoperative plasma cholinesterase activity as a risk marker of postoperati...
Cerejeira, J; Batista, P; Nogueira, V; Vaz-Serra, A; Mukaetova-Ladinska, EBBACKGROUND: delirium is a frequent neuropsychiatric syndrome affecting medical and surgical elderly patients. Cholinergic dysfunction has been implicated in delirium pathophysiology and plasmatic acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activities are suppressed in patients with delirium. In this cohort study, we investigated whether these changes emerge during delirium or whether they are ...
SnO2 extended gate field-effect transistor as pH sensor
Batista,P. D.; Mulato,M.; Graeff,C. F. de O.; Fernandez,F. J. R.; Marques,F. das C.Extended gate field-effect transistor (EGFET) is a device composed of a conventional ion-sensitive electrode and a MOSFET device, which can be applied to the measurement of ion content in a solution. This structure has a lot of advantages as compared to the Ion- Sensitive Field Effect Transistor (ISFET). In this work, we constructed an EGFET by connecting the sensing structure fabricated with SnO2 to a commerci...
Vegetable proteins and milk puddings
Sousa, Isabel; Nunes, M.C.; Batista, P.; Raymundo, Anabela; Alves, M.M.In recent years, interest in animal free foods has increased tremendously due to factors like BSE crisis, rise of nutritionally dependent illnesses, like diabetes type II, cardiovascular and digestive diseases, along with ethic orientations of denying animal intakes of any kind. The use of proteins from leguminous seeds as an alternative to the animal proteins in dairy desserts was studied. Lupin, pea and soya ...
Rice hull-derived silica: applications in Portland cement and mullite whiskers
Souza,M.F. de; Batista,P.S.; Regiani,I.; Liborio,J.B.L.; Souza,D.P.F. deSilica was extracted from rice hulls by three processing routes, starting with acid treatment followed by burning and milling. The amorphous white silica powder showed a surface area of 260 to 480 m²/g, purity above 99% and average particle size of 2.0 to 0.6 mm. This silica is suitable for the preparation of mullite whiskers employing the rare earth aluminosilicate glass technique. Due to its highly pozzolanic...
O perfil de temperatura na região da mesopausa em São José dos Campos (23° S, 4...
Jorge,M. P. P. M.; Clemesha,B. R.; Batista,P. P.; Simonich,D. M.Este artigo trata da obtenção do perfil de temperatura atmosférica entre 80 e 100 km de altura, região da mesopausa. Ele é baseado no desenvolvimento e aprimoramento de uma técnica experimental simples que permite determinar a temperatura da atmosfera utilizando um radar de laser e as propriedades físicas do sódio mesosférico. A técnica consiste em sintonizar o radar de laser na linha D2 do sódio (5890 Å) e sub...
Wave-associated sporadic neutral layers in the upper atmosphere
Clemesha,B. R.; Batista,P. P.; Simonich,D. M.Sporadic neutral layers, with thicknesses between a few hundred meters and several kilometers, are observed by lidar in the same height range as ionospheric sporadic E. Ns layers were first observed in sodium, 20 years ago, and more recently have also been seen in potassium, iron and calcium. As in the case of Es there is a strong link with atmospheric waves, and a number of studies have shown evidence for a po...
Familial infection by the hepatitis C virus.
Miranda, H P; Departamento de Medicina, Hospital Geral de Santo António, Porto.; Batista, P; Oliveira, F; Barros, HThe aim of this study was to evaluate the prevalence of the antibody to hepatitis C virus (HCV) in the relatives of cases of asymptomatic chronic hepatitis C infection, detected during routine blood donation, and determine risk factors for the presence of the infection in the family setting. Two hundred and eighty-five relatives (spouses, offspring, siblings and parents) of 87 index cases were studied. Anti-HCV...
