conclusions combination therapy with surgical excision has a synergistic effect and appears to be the best treatment for extended lesions. however, new potent antibacterial drugs may help to improve the management of such infections when there are sufficient data on their in vitro activity. introduction nocardia species are described as opportunistic pathogens that mainly cause pulmonary nocard...

background chlorhexidine gluconate (chx) is the most common antimicrobial agent used against oral pathogens, however information on its ability to inhibit and disrupt anaerobic single and multispecies biofilms is relatively unknown. objectives the purpose of this study was to test the efficacy of chx for its biofilm inhibition and disruption properties using crystal violet assay. materials and ...

seeds of the castor bean plant ricinuscommunis l (cb) contain ricin toxin (rt), one of the most poisonous naturally-occurring substances known. ricin toxin, a water-soluble glycoprotein that does not partition into the oil extract, is a ribosome-inactivating toxin composed of two chains, labeled a and b. severity of the toxicity varies depending on the route of exposure to the toxin. inhalation...

background: marginal seal has a principal role in durability and clinical success offissure sealants. the aim of this study was to compare the microleakage of two materials used as pit and fissure sealant with different methods of application. methods: the 55 extracted premolars were assigned randomly to one ofthe following five groups: group 1: acid-etching (ultra-etch) + fissure sealant (conv...

În cadrul acestei lucrări sunt explorate soluţii de aplicare a specificaţiilor IEC 61499 în modelarea şi implementarea controlului de nivel înalt al holonilor. Conceptele IEC 61499 au fost utilizate ca o tehnologie suport pentru încapsularea controlului inteligent al holonilor, modelarea comunicaţiei interholonice şi configurarea dinamică a holonilor. Modelele şi teoriile propuse au fost valida...
