PURPOSE Actinic keratosis (AK) is an incipient form of cutaneous squamous cell carcinoma (SCC). We determined if the pattern of expression of keratin-14 (K14) is a factor for tumor progression in AK and SCC. MATERIALS AND METHODS Eighteen sections from the tissues of 16 patients were stained with anti-K14 antibody and p16(INK4a). Among the 16 patients, 4 were diagnosed with both SCC and AK at...

background: the aim was to compare three different methods (direct examination, culture and pcr meth­ods) for the diagnosis of acanthamoeba keratitis (ak) in corneal scrapes. methods: twenty eight corneal scrapes and contact lenses were collected from keratitis patients and re­ferred to the de­partment of medical parasitology and mycology, school of public health, tehran univer­sity of medical ...

purpose : acanthamoeba keratitis (ak) is a sight-threatening corneal infection with a rapidly increased incidence since 1990s along with the growing popularity of contact lenses. in this study we aimed to study patients with ak and its associated risk factors in farabi eye hospital of tehran, focusing on those with more severe corneal involvement. methods : patients with clinical or laboratory ...

Given an integral “stamp” basis Ak with 1 = a1 < a2 < . . . < ak and a positive integer h, we define the h-range n(h, Ak) as n(h, Ak) = max{N ∈ N | n ≤ N =⇒ n = k ∑

We study some relations between a reproducing cone K in a linear space V over a fully ordered field F and the cone I(K) in Hom( V, V) consisting of all operators A such that AK G K. In particular, indecomposable cones are considered.

In this contribution we investigate the impact of the fluid-air interface on the dissolved electrolyte Potassium hexacyanoferrate K4[Fe(CN)6] by infrared-visible sum-frequency generation spectroscopy (SFG) and surface tension measurements. SFG is a surface specific nonlinear optical technique that records the vibrational spectrum of the adsorbed species with little to no contribution from the b...

In the field of software architecture, a paradigm shift is occurring from describing the outcome of architecting process to describing the Architectural Knowledge (AK) created and used during architecting. Many AK models have been defined to represent domain concepts and their relationships, and they can be used for sharing and reusing AK across organizations, especially in geographically distr...

the aim of this paper is a) if σak2 < ∞ then σak rk(x) is in bmo that{rk(x)} is rademacher system. b) p1k=1 ak!nk (x) 2 bmo; 2k  nk < 2k+1that f!n(x)g is walsh system. c) if jakj < 1k then p1k=1 ak!k(x) 2 bmo.

If E = {ei} and F = {fi} are two 1-unconditional basic sequences in L1 with E r-concave and F p-convex, for some 1 ≤ r < p ≤ 2, then the space of matrices {ai,j} with norm ∥{ai,j}∥E(F ) = ∥∥∑ k ∥ ∑ l ak,lfl∥ek ∥∥ embeds into L1. This generalizes a recent result of Prochno and Schütt.
