AIMS AND OBJECTIVES The aim and objective of the study were to determine the incidence of flare-ups during endodontic treatment and to identify the risk factors associated with flare-ups. SUBJECTS AND METHODS A total of 1725 patients who were treated during the time period of 2009-2014 by the same endodontist were reviewed. Incidence of flare-up, patients' age, gender, status of pulp, tooth p...

GRB050904 is very interesting since it is by far the most distant GRB event known to date(z = 6.29). It was reported that during the prompt high energy emission phase, a very bright optical flare was detected, and it was temporal coincident with an X-ray flare. Here we use two models to explain the optical flare, One is the “late internal shock model”, in which the optical flare is produced by ...

BACKGROUND We found the first evidence of the efficacy of a herbal treatment with myrrh, dry extract of chamomile flowers, and coffee charcoal for ulcerative colitis (UC). However, the impact of the herbal treatment on the CD4+ T-cell compartment, which is essential for both the induction of UC and the maintenance of tolerance in the gut, is not well understood. AIM To analyze the frequency a...

Designing a statistical solar flare forecasting technique can benefit greatly from knowledge of the flare frequency of occurrence with respect to sunspot groups. This study analyzed sunspot groups and Hα and X-ray flares reported for the period 1997 – 2007. Annual catalogs were constructed, listing the days that numbered sunspot groups were observed (designated sunspot group-days, SSG-Ds) and f...

Flare and hyperalgesia after intradermal capsaicin injection in human skin. J. Neurophysiol. 80: 2801-2810, 1998. We investigated the neurovascular mechanisms that determine the flare response to intradermal capsaicin injection in humans and delineated the associated areas of mechanical and heat hyperalgesia. The flare response was monitored both visually and with infrared telethermography. The...

In this study we compile for the first time comprehensive data sets of solar and stellar flare parameters, including flare peak temperatures Tp, flare peak volume emission measures EMp, and flare durations τf from both solar and stellar data, as well as flare length scales L from solar data. Key results are that both the solar and stellar data are consistent with a common scaling law of EMp ∝ T...

OBJECTIVE To determine whether relationships exist between elevated laser flare photometry values and common abnormalities and complications associated with uveitis. METHODS We retrospectively studied all patients with uveitis on whom laser flare photometry measurements ("flare") were obtained (N = 111) at 2 academic medical centers. The first laser flare photometry values obtained for each p...

BACKGROUND Systemic lupus erythematosus (SLE) is characterized by the aberrant activation of T-lymphocytes. Since T-bet is the principal transcription factor for the differentiation of type-1 helper T-lymphocyte, we study the impact of urinary T-bet mRNA expression in clinically quiescent SLE patients on the risk of subsequent disease flare. METHODS We studied 60 quiescent SLE patients. Urina...

The purpose of this study was to evaluate the effects of extracts of Coptidis rhizoma, Phellodendri cortex and Gardeniae fructus, which are medicinal herbs in Orengedoku-to (Huanglin-Jie-Du-Tang in Chinese), and crocetin (a major component of Gardeniae fructus) on experimental elevation of aqueous flare in pigmented rabbits. To produce aqueous flare elevation, 0.5 microg/kg lipopolysaccharide (...

BACKGROUND Kaposi sarcoma (KS) flare may occur following therapy with corticosteroids, as part of the immune reconstitution inflammatory syndrome seen with highly active antiretroviral therapy (HAART), and after rituximab therapy. The exact mechanism responsible for iatrogenic KS flare is unclear. METHODS A case of AIDS-associated cutaneous KS flare following rituximab therapy was compared to...
