Results: In each case, lasers permitted safe treatments of BOVLs

Results: In each case, lasers permitted safe treatments of BOVLs without hemorrhages, both during the intervention and in the post-operative period. The minimally invasive techniques (TMT and ILP) permitted even the safe resolution of big lesions without tissue loss.

Conclusions: Laser devices confirm

to be the gold standard in BOVLs treatment, permitting even the introduction of minimal invasive surgery principles and reducing MK-2206 PI3K/Akt/mTOR inhibitor the risks of hemorrhage typical of these neoplasms. As usual in laser surgery, it is necessary a clear knowledge of the devices and of the laser-tissue interaction to optimize the results reducing risks and disadvantages.”
“The current work deals with the studies on characterization of two biofilm-forming bacteria isolated from the oral cavity.

The major constituent of biofilm other than bacterial cells is the extracellular polymeric substance (EPS) matrix, which is secreted by the bacterial cells themselves. Physical properties of biofilms such as attachment, mechanical strength, antibiotic resistance can be attributed to EPS matrix. Molecular phylogeny confirmed these two isolates as Pseudomonas aeruginosa GW-572016 in vivo and Bacillus subtilis. It was observed that cell attachment in both the strains was maximal when xylose was used as the sole carbon source. The EPS characterization result indicated the presence of a macromolecular complex constituting of carbohydrate, protein, lipids and nucleic acids. Test for biofilm formation in the presence of metal salts of iron and zinc showed moderate to high inhibition of biofilm formation. However, calcium, iron and copper have been found to enhance biofilm growth

significantly. There was more than 50 % increase in biofilm growth by P. aeruginosa with an increase in calcium concentration up to 80 ppm (Two tailed t-test P < 0.05), whereas a parts per thousand yen 15 % increase in biofilm growth by B. subtilis KPT-8602 mouse was observed in the presence of 80 ppm of calcium. However, variations were significant (Two way ANOVA, P < 0.01) between different metals in different concentrations. In this study, attempts have been made to examine the effect of different carbon sources and physiological conditions on biofilm growth.”
“Objective: To report normal tear production of healthy adult black-tufted marmosets and propose a novel alternative for the measurement of the aqueous portion of tear production in animals with small eyes.

Animal studied: Black-tufted marmosets (Callithrix penicillata).

Procedures: Tear production of 19 animals was evaluated by the following methods: modified Schirmers I, phenol red thread and the novel use of standardized endodontic absorbent paper points. These methods and results were compared. Additionally, blink frequency and palpebral fissure length were measured.

Results: Modified Schirmers test I, mean = -0.46 +/- 3.41 mm/min; Phenol red thread, mean = 13.
