PURPOSE To evaluate the role of topical betaxolol on experimental ocular inflammation in rabbits. METHOD Transcorneal diffusion of highly selective agonists for prostaglandin E2 receptor subtypes (EP), 25 microg/ml, with the use of a glass cylinder, was performed to produce aqueous flare elevation in pigmented rabbits. Betaxolol was topically administered before EP agonist application. Aqueou...

The purpose of this research is to investigate the frequency of endodontic flare-ups using a visual analogue scale. Definitions of flare-ups vary widely as does their reported frequency. A flare-up was defined as an increase of 20 or more points on the visual analogue scale for a given tooth, within the periods of 4 h and 24 h after the initial treatment appointment. The data from a previous st...

A problem that an endodontist can encounter during the course of root canal treatment is pain and swelling or both in the form of flare-ups. The causes for this flare-up are numerous which include mechanical, chemical, microbial injury to the pulp or periradicular tissues, whereby an acute periradicular inflammation results. This situation can be prevented by selection of instrumentation techni...

Aim: The aim of this research was to investigate the level pollutants deposition on soil generated from a gas flaring site.
 Study Design: Soil Samples for study were picked two sets locations (a proposed flare site situated at Ogbogu Gas plant and control sites sfrom primary source local farm lands). A total number eighteen samples collected five different sampling spots as designated usi...

Spondyloarthritis (SpA) is a chronic inflammatory rheumatic disease with many phenotypes, but the frame of the disease is still a matter of debate, particularly regarding the non-radiographic forms of axial SpA. 3 The disease evolution may have several profiles, mainly related to the treatment strategy, balancing from periods of remission or low disease activity to flares of the disease. The re...

Open dumping and landfilling are the prevalent solid waste disposal practices in Thailand. Surveys on the disposal sites revealed the presence of 95 landfills and 330 open dumps. Methane emission potential at these sites was estimated by three methods. Results of the Intergovernmental Panel on Climate Change (IPCC) method, Landfill Gas Emission model (LandGEM), and closed flux chamber technique...

PURPOSE Pain flare is a temporary increase in pain and is a potential side effect of radiotherapy treatment. However, its incidence has been reported only in recent studies, and with great variability. A few studies have reported on the use of dexamethasone as a prophylactic agent in the prevention of pain flare. The objective of this study is to present a review of the available literature reg...

AIM To determine the incidence of flare-up and the effect of age, gender, visit type, treatment duration, preoperative pain and intraoperative pain on flare-up in Nigerian adults. MATERIALS AND METHODS A total of 175 participants, aged 18 to 60 years with a necrotic central incisor, with or without preoperative pain, participated. They received postoperative paracetamol tablets and were asked...

UNLABELLED BACKGROUND The biological importance of members of genus Ferula promoted us to investigate the leaves of Ferula vesceritensis Coss et Dur. (endemic plant) previously not investigated. This study presents the chemical composition and antibacterial activities of the hydrodistilled oils. RESULTS Volatile components of the leaves of F. vesceritensis have been studied by gas chromato...

Oxygen transport across the cathode gas diffusion layer (GDL) in polymer electrolyte membrane (PEM) fuel cells was examined by varying the O2/N2 ratio and by varying the area of the GDL extending laterally from the gas flow channel under the bipolar plate (under the land). As the cathode is depleted of oxygen, the current density becomes limited by oxygen transport across the GDL. Oxygen deplet...
