Segmental neurofibromatosis type I (SNF-I) is a rare variant of neurofibromatosis (NF). It is classified as NF type V and defined as cafe'-au-lait macules and/or neurofibromas in a single ,unilateral segment of the body .We report two cases with SNF-I with striking similar manifestations.

herpetic keratitis which is resulted from herpes simplex virus type i, is considered the most common cause of corneal blindness that needs being diagnosed and treated in order to prevent irreversible eye effects. the best method to diagnose it is molecular method which has high sensitivity and exclusivity. the current study was done on 25 eye samples collected from patients referred to the feyz...

type i diabetes mellitus (dm) is frequently associated with autoimmune thyroid disease (atd). association of atd and type i dm has been described with varying frequencies but there is still debate about the situation in the iranian population. we investigated the prevalence of anti thyroid peroxidase (anti-tpo) antibodies and atd in children and adolescents with type i dm. a total of 145 patien...

when grown in monolayer culture at low density and with the addition of serum, cartilage cells dedifferentiate or are overgrown by fibroblast-like cells. the aim of this study was to optimize the cultivation of chondrocytes in monolayer culture and to slow down their transformation or their overgrowth by fibroblast-like cells. the interaction between chondrocytes and cartilage-specifc matrix is...

statement of problem: nowadays mineral trioxide aggregate (mta) is widely used for root end fillings, pulp capping, perforation repair and other endodontic treatments. investigations have shown similar physical and chemical properties for portland cement and root mta with those described for mta. purpose: the aim of this in vitro study was to evaluate the tissue reaction to implanted mta, portl...

In this paper, using Clarke’s generalized directional derivative and dI-invexity we introduce new concepts of nonsmooth K-α-dI-invex and generalized type I univex functions over cones for a nonsmooth vector optimization problem with cone constraints. We obtain some sufficient optimality conditions and Mond-Weir type duality results under the foresaid generalized invexity and type I cone-univexi...

human t lymphotropic virus type i (htlv-i) is a retrovirus which is associated with adult t cells leukaemia (atl) and htlv-i-associated myelopathy/tropical spastic paraparesis (ham/tsp) in a minority of htlv-i-infected individuals. it is not clear why a minority of htlv-i-infected individuals develop ham/tsp and majority remains lifelong carriers. it seems that the interaction between the virus...
