Background: Many efforts are made to find new and more effective treatments for psoriasis. Intralesional 5-Fluorouracil (5-FU) +epinephrine is a cheap option which can be administered with long intervals. The effectiveness of Pulse Dye Laser (PDL) on psoriasis has been already assessed. We decided to evaluate the effectiveness of 5-FU+epinephrine and compare it to betamethasone and PDL.</...

The interpretation of propositional dynamic logic (PDL) through Kripke models requires the relations constituting the interpreting Kripke model to closely observe the syntax of the modal operators. This poses a significant challenge for an interpretation of PDL through stochastic Kripke models, because the programs’ operations do not always have a natural counterpart in the set of stochastic re...

The mechanisms linking acinar cell apoptosis and ductal epithelial proliferation remain unknown. To determine the relationship between these events, pancreatic duct ligation (PDL) was performed on p53(+/+) and p53(-/-) mice. In mice bearing a wild-type p53 allele, PDL resulted in upregulation of p53 protein in both acinar cells and proliferating duct-like epithelium. In contrast, upregulation o...

Ruffini nerve endings in the periodontal ligament (PDL) of aged mouse maxillary incisors were investigated by means of immunohistochemistry for protein gene product 9.5 (PGP 9.5) at light and electron microscopic levels. C3H/HeSlc mice were sacrificed by perfusion fixation. Frozen sagittal cryostat sections of decalcified maxillary incisors were prepared and stained by anti-PGP 9.5 antibody, fo...

BACKGROUND The use of platelet rich plasma (PRP, GLO) has been used as an adjunct to various regenerative dental procedures. The aim of the present study was to characterize the influence of PRP on human gingival fibroblasts, periodontal ligament (PDL) cells and osteoblast cell behavior in vitro. METHODS Human gingival fibroblasts, PDL cells and osteoblasts were cultured with conditioned medi...

treatment. The effect of PDL could be explained by its selective action on the telangiectatic component of the lesion, leading to destruction of the vessels that nourish the sebaceous hyperplasia. This treatment was recently described with in vivo confocal microscopy imaging before and after treatment with PDL, showing that a few minutes after application of the beam the vessels surrounding the...

We study the complexity of satisfiability in the expressive extension ICPDL of PDL (Propositional Dynamic Logic), which admits intersection and converse as program operations. Our main result is containment in 2EXP, which improves the previously known non-elementary upper bound and implies 2EXPcompleteness due to an existing lower bound for PDL with intersection. The proof proceeds by showing t...

The performance description language PDL provides a compact notation for the speciication of non-functional attributes of VLSI systems. This paper presents evaluation mechanisms which allow the designer to assert performance goals on PDL models of VLSI systems and determine if the constrained models are satissable. This is done by developing a PDL performance model and constructing a constraint...
