This study assessed the effect of bleaching protocols with 38% hydrogen peroxide (HP) and post-bleaching times on shear bond strength of a composite resin to dentin. One-hundred slabs of intracoronary dentin were included and randomly assigned into 2 groups according to the bleaching protocol: HP (2 applications of 10 min each) and HP activated by LED laser (2 applications of 10 min each/45 s o...

OBJECTIVE The purpose of this article is to illustrate the spectrum of pathologic and high-resolution CT features of hypersensitivity pneumonitis (HP). CONCLUSION High-resolution CT plays an important role in the diagnosis of HP. A confident diagnosis of subacute HP is based on the presence of ground-glass opacities, poorly defined centrilobular nodules, and mosaic attenuation on inspiratory ...

BACKGROUND Helicobacter pylori (HP) and Epstein-Barr virus (EBV) have been associated with cancer development. We evaluated the prevalence of HP, HP CagA+ and EBV infection in gastric cancer (GC) samples from adults and in gastric tissues from patients who underwent upper endoscopy (UE). METHODS Samples from UE and GC were collected to investigate the presence of HP infection and the HP virul...

Hazard classification of waste is a necessity, but the hazard properties (named "H" and soon "HP") are still not all defined in a practical and operational manner at EU level. Following discussion of subsequent draft proposals from the Commission there is still no final decision. Methods to implement the proposals have recently been proposed: tests methods for physical risks, test batteries for...

Introduction: Hypericum perforatum L was coded in medicinal plants research center of Shaheed Beheshti university and using decoction method was extracted. There are many reports concerning the antidepressant effects of Hypericum perforatum L. (HP), but there are few studies indicating its antinociceptive effects of Hypericum specially Hypericum perforatum L. Materials & Methods: In this expe...

background: the major cause of peptic ulcer disease is helicobacter pylori (hp), and it is also implicated in the pathogenesis of adenocarcinoma of the distal stomach and gastric lymphoma. the incidence of peptic ulcer disease, atrophic gastritis, and gastric adenocarcinoma are more common in people infected of caga positive strains of hp. the aim of this study was to determine the prevalence o...

the effect of three levels (0, 28.65, 57.31mg /200mg substrate) of golpar (heracleum persicum: hp) on in vitro rumen ecosystem and on methane production was assessed. gas production (gp) was recorded from 1 to 54h past of incubation. the parameters studied were in vitro gas production (ivgp), methane production, ammonia-n concentration (nh3-n), in vitro organic matter degradability (ivomde), pa...

autoimmune thyroid diseases (atd) are multifactorial conditions that result from genetic predisposition in combination with environmental risk factors. helicobacter pylori infection as an environmental risk factor has been proposed to imitate the antigenic components of the thyroid cell membrane and may play a leading role in the onset of the autoimmune diseases, such as hashimoto thyroiditis. ...

The cumulative second-harmonic analysis of ultrasonic Lamb wave has been performed to study the precipitation kinetics and microvoid initiation of ferritic Cr-Ni alloy steel during the ageing process. Ageing of ferritic Cr-Ni alloy materials have been done at 1223 K and 1173 K for different degradation time intervals and air cooled. The results show that the normalized acoustic nonlinearity of ...
