Seeking harmony in coastal development for small islands: Exploring multifuncti...
K Ng; M R Phillips; H Calado; P Borges; F Veloso-GomesThe Azores is a remote archipelago rich in biodiversity, geodiversity and cultural heritage located in the middle of the North Atlantic Ocean. It comprises nine volcanic Small Islands (SIs) scattered over 600 km and are vulnerable to coastal hazards due to limited land availability and ocean exposure. To mitigate and adapt to hazards and human occupation, traditional hard-engineering structures have been used. ...

Noncrystalline uric acid inhibits proteoglycan and glycosaminoglycan synthesis ...
Borges,F.T.; Dalboni,M.A.; Michelacci,Y.M.; Schor,N.Hyperuricemia is associated with renal stones, not only consisting of uric acid (UrAc) but also of calcium oxalate (CaOx). Glycosaminoglycans (GAGs) are well-known inhibitors of growth and aggregation of CaOx crystals. We analyzed the effect of noncrystalline UrAc on GAG synthesis in tubular distal cells. MDCK (Madin-Darby canine kidney) cells were exposed to noncrystalline UrAc (80 µg/mL) for 24 h. GAGs were l...
Modeling electrodialysis and a photochemical process for their integration in s...
Borges,F. J.; Roux-de Balmann,H.; Guardani,R.Oxidation processes can be used to treat industrial wastewater containing non-biodegradable organic compounds. However, the presence of dissolved salts may inhibit or retard the treatment process. In this study, wastewater desalination by electrodialysis (ED) associated with an advanced oxidation process (photo-Fenton) was applied to an aqueous NaCl solution containing phenol. The influence of process variables...
Passeio Geológico da Foz do Douro: Consciencialização para a Geoconservação
M.Sousa; S. Aires; V. Ramos; C. Vasconcelos; M.M. Marques; L. Borges; F. NoronhaThe "Foz do Douro Geological Walk" has contributed to the public awareness of the Porto shoreline geoconservation. Considering the different school Knowledge, and in order promote significant practices in the aim of Geology, it was created in 2008 an Interpretative Centre and developed some science education materials. The investment in this project has proven to be fructiferous ; A criação do "Passeio Geológi...
Performance of Argon-Xenon Mixtures in a Gas Proportional Scintillation Counter...
Carmo, S. J. C. do; Borges, F. I. G. M.; Conde, C. A. N.The performance of a gas proportional scintillation counter filled with either pure Xe or Ar-Xe mixtures is described for the 0.1-10 keV X-ray energy range. It is shown that the spectra tail distortion exhibited by Xe filled gaseous detectors for soft X-rays below 2 keV is reduced if Ar-Xe mixtures are used. The peak-to-valley ratio increases by a factor of about 2 or 3 as the Xe concentration is reduced from 1...
Anatomia e histoquímica das folhas de Senna alata
Rodrigues,I.M.C.; Souza Filho,A.P.S.; Ferreira,F.A.; Ilkiu-Borges,F.; Gurgel,E.S.C.Senna alata é uma espécie daninha frequente em pastagens da região amazônica, cujas folhas apresentam propriedades medicinais. Indivíduos dessa espécie foram cultivados e coletados no Campo Experimental da Embrapa Amazônia Oriental, em Belém-PA, para a realização de análises anatômica e histoquímica das folhas, com a finalidade de fornecer elementos para a taxonomia, identificação microscópica de aleloquímicos ...
Gentamicin-induced preconditioning of proximal tubular LLC-PK1 cells stimulates...
Pessoa,E.A.; Convento,M.B.; Silva,R.G.; Oliveira,A.S.; Borges,F.T.; Schor,N.Nephrotoxicity is the main side effect of antibiotics such as gentamicin. Preconditioning has been reported to protect against injuries as ischemia/reperfusion. The objective of the present study was to determine the effect of preconditioning with gentamicin on LLC-PK1 cells. Preconditioning was induced in LLC-PK1 cells by 24-h exposure to 2.0 mM gentamicin (G/IU). After 4 or 15 days of preconditioning, cells w...
Epigenetic reprogramming and small RNA silencing of transposable elements in po...
Slotkin, R.K.; Vaughn, M.; Borges, F.; Tanurdzic, M.; Becker, J.D.; Feijó, J.A.; Martienssen, R.The mutagenic activity of transposable elements (TEs) is suppressed by epigenetic silencing and small interfering RNAs (siRNAs), especially in gametes that could transmit transposed elements to the next generation. In pollen from the model plant Arabidopsis, we show that TEs are unexpectedly reactivated and transpose, but only in the pollen vegetative nucleus, which accompanies the sperm cells but does not prov...
