BACKGROUND/AIM Angiopoietin 1 and 2 interact with vascular endothelial growth factor (VEGF) to promote angiogenesis in animal and in vitro models. Although VEGF concentrations are elevated, there is little information regarding angiopoietin concentration in the vitreous of patients with diabetic retinopathy. METHODS Angiopoietin concentrations were measured by luminescence immunoassay in vitr...

In any wireless communication environment in which a transmitter creates interference to the others, a system of non-linear equations arises. Its form (for 2 terminals) is p1=g1(p2;a1) and p2=g2(p1;a2), with p1, p2 power levels; a1, a2 quality-of-service (QoS) targets; and g1, g2 functions akin to "interference functions" in Yates (JSAC, 13(7):1341-1348, 1995). Two fundamental questions are: (1...

Occupational exposure limits (OELs) are used as an important regulatory instrument to protect workers' health from adverse effects of chemical exposures. The OELs mirror the outcome of the risk assessment and risk management performed by the standard setting actor. In this study we compared the OELs established by 18 different organisations or national regulatory agencies. The OELs were compare...

BACKGROUND: Canal wall down and canal wall up mastoidectomy represent two surgical approaches to middle ear cleft pathology. Very few studies have examined the effects of these procedures both on the patients' well being and on the resources needed to maintain that state. In this study the authors report the outpatient attendance pattern of canal wall down mastoidectomy patients METHODS: This i...

We review the class of partial-propensity exact stochastic simulation algorithms (SSA) for chemical reaction networks. We show which modules partial-propensity SSAs are composed of and how partial-propensity variants of known SSAs can be constructed by adjusting the sampling strategy used. We demonstrate this on the example of two instances, namely the partial-propensity variant of Gillespie’s ...

AIM The present study was aimed to evaluate E. granulosus genotypes isolated from goats using HRM analysis in Isfahan province. BACKGROUND Cystic echincoccosis, so-called hydatidosis, is widespread infection caused by the larval stage of Echinococcus granulosus. This is an important zoonotic disease worldwide, especially in the developing countries such as Iran. To date, molecular studies mai...

BACKGROUND In the debate about legalization of euthanasia very little attention has so far been given to the opinion of the patient. OBJECTIVE To assess the opinion of persons with HIV infection in Europe. METHODS A cross-sectional survey of persons with HIV infection attending HIV/AIDS treatment centres or HIV support organizations in 11 European Union Member States was performed. A total ...
