Measurement of changes in buccal mucosal potential difference produced by contact with drug formulations may provide a means of predicting their mucosal toxicity and ulcerogenic activity.

Background: Following shortage of Carmustine, BeEAM regimen (Bendamustine, Etoposide, Cytarabine and Melphalan) was used before autologous transplant in relapsed/refractory lymphoma patients. We evaluated safety efficacy compared to BEAM. Patients methods: Ninety consecutive patients receiving (30pts) (Bendamustine 100, 120 or 200 mg/m²/d) BEAM (60 pts) were retrospectively analyzed. Results...

persea americana is a plant used by traditional medicine practitioners to treat ailments including diarrhoea and diabetes mellitus in nigeria. hence, the chloroform and the methanol fractions of the chloroform-methanol extract of the leaves of p. americana were evaluated for their acute toxicity as well as anti-diarrhoeal effects in wistar rats to substantiate this claim. the chloroform and met...

biochemical characteristics of α-amylase in the digestive system and head glands of cryptolaemus montrouzieri, a key predator of citrus mealybug, planococcus citri (pseudococcidae), were studied. the major isoform of α-amylase with the same molecular weight was detected in both gut and head glands loaded on polyacrylamide-starch gel electrophoresis. moreover, a minor band with much lower intens...

cu-mo and cu-ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. the effects of process parameters such as film thickness, annealing duration and temperat...

PURPOSE The purpose of this study was to evaluate cell toxicity due to ion release caused by galvanic corrosion as a result of contact between base metal and titanium. MATERIALS AND METHODS It was hypothesized that Nickel (Ni)-Chromium (Cr) alloys with different compositions possess different corrosion resistances when contacted with titanium abutment, and therefore in this study, specimens (...

A prospective study included 30 patients with chronic renal insufficiency undergoing chronic chemodialysis, with or without digestive problems, who underwent proximal endoscopy for pretransplantation balance in the period 1998-2000. The study included patients admitted to the Institute of Nephrology and Chemodialysis of the Clinical Centre in Nis and Nephrology Clinic of the Clinical Centre of ...

Background: Magnetite (Fe3O4) nanoparticles are currently one of the important and acceptable magnetic nanoparticles for biomedical applications. To use magnetite nanoparticles for bacteria cell separation, the surface of nanoparticles would be modified for immobilizing of nanoparticles on the surface of bacteria. Functionalization of magnetite nanoparticles is performed by different s...
