Background: Lichen planus (LP) is an idiopathic papulosquamous disorder, which can show cutaneous or mucosal signs. It is caused by a cell mediated immune response to an antigen. A wide range of clinical manifestations has been reported. Objective: To determine the sex and age frequency and clinical presentations of this disease in patients referred to Razi hospital in Tehran. Patients and Meth...

From a well represented sample of world languages Steele (1978) shows that about 70% of languages exhibit significant word order variation. Only recently has this wlde-spread phenomenon been drawing appropriate attention. Perhaps ID/LP (Immediate Dominance and Linear Precedence) framework is the most debated theories in this area. We point out some difficulties in processing standard ID/LP gram...

We study combinatorial modulus on self-similar metric spaces. We give new examples of hyperbolic groups whose boundaries satisfy a combinatorial version of the Loewner property, and prove Cannon’s conjecture for Coxeter groups. We also establish some connections with lp-cohomology.

Background: Lumbar puncture (LP) is a worth procedure in diagnosis of oncological diseases and intrathecal administration of antineoplastic drugs. The effort should be to minimize pain of LP in children with cancers. This clinical trial was done to compare success rates in performing LP and reducing anxiety and pain of LP in sitting and lateral decubitus positions in 1 to 5-year-old children. ...

We prove that the first reduced cohomology with values in a mixing Lp-representation, 1 < p < ∞, vanishes for a class of amenable groups including amenable Lie groups. In particular this solves for this class of amenable groups a conjecture of Gromov saying that every finitely generated amenable group has no first reduced lp-cohomology. As a byproduct, we prove a conjecture by Pansu. Namely, th...
