Article history: Received 18 September 2003 Received in revised form 20 September 2005 Accepted 3 November 2005 Available online 18 January 2006 The empirical environmental Kuznets curve (EKC) literature is vast but far from conclusive. Many authors have analysed the existence of an EKC for various pollutants. Others have used the EKC framework to identify country characteristics that help to e...

PURPOSE To identify the long term clinical course of amblyopia and strabismus that developed secondary to a monocular corneal opacity following suspected epidemic keratoconjunctivitis (EKC) in infancy. METHODS This was a retrospective study analyzing the medical records of seven patients, treated in our clinic, who were followed for more than five years. RESULTS Four patients in our clinic ...

This research focuses on four cases of patients having undergone eximer laser photorefractive surgery who were diagnosed with adenoviral keratoconjunctivitis during the postoperative period and who later developed epidemic keratoconjunctivitis (EKC)-like keratitis. Two of the patients had undergone laser-assisted subepithelial keratectomy (LASEK), one had undergone laser in situ keratomileusis ...

PURPOSE To report the use of photorefractive keratectomy (PRK) with mitomycin-C (MMC) to treat concomitant myopia and visually significant infiltrates associated with epidemic keratoconjunctivitis (EKC). SETTING Ophthalmic Consultants of Long Island, Nassau University, Long Island, New York, USA. DESIGN Interventional case series. METHODS Consecutive patients with myopia and recalcitrant ...

PURPOSE Epidemic keratoconjunctivitis (EKC) is a severe ocular infection caused by a few types (8, 19a [relabeled as 64 recently], 37, 53, and 54) of human adenoviruses (HAdVs). HAdVs are known for their strong host species specificity that limits studying HAdV virulence and pathophysiology in animal models. METHODS A HAdV infection model of primary porcine corneal epithelial cells (PPCE) and...

The empirical literature on the environmental Kuznets curve (EKC) purports to describe how a nation's environmental quality will evolve if it makes the transition from poverty to wealth. The popular generalization is that pollution will first increase and then, if income becomes sufficiently high, decline. Empirical support for this proposition is based primarily on crosscountry variations in i...

The environmental Kuznets curve (EKC) hypothesis assumes that there is an inverted U-shaped relationship between environmental degradation and income per capita. In other words, as a country grows, it is assumed that its environmental quality improves. In this study, we aim to test the EKC hypothesis for 12 Middle East countries during the period 1990–2008 by employing recently developed panel ...

N(6)-threonylcarbamoyladenosine (t(6)A) is a universal tRNA modification essential for normal cell growth and accurate translation. In Archaea and Eukarya, the universal protein Sua5 and the conserved KEOPS/EKC complex together catalyze t(6)A biosynthesis. The KEOPS/EKC complex is composed of Kae1, a universal metalloprotein belonging to the ASHKA superfamily of ATPases; Bud32, an atypical prot...

Cross-country estimations of the Environmental Kuznets Curve (EKC) to empirically analyze the relationship between income and pollution have generally assumed a common structure for all countries. Since this latter feature is not supported by economic theory, this paper uses the Random Coefficient Model proposed by Swamy (1970) and empirically estimates EKCs for sulfur dioxide with specific tur...

Epidemic keratoconjunctivitis (EKC), caused by certain species D human adenoviruses (Ads), is a highly contagious severe disease involving both the conjunctiva and cornea. The hallmark of this disease is the subepithelial infiltration of leukocytes, which results in corneal opacities that may persist for months or even years. In this case, of a 6-month-old infant, we report a symblepharon forma...
