background and aims. oral lichen planus (olp) is an immunologic disorder. a large number of studies have reported that lipid rafts have a key role in receptor signaling of lymphocytes. here, we explore the potential of lipid rafts as targets for the development of a new class of agents to down-modulate immune responses and treat autoimmune diseases. materials and methods. the present cross-sect...

It has been recently shown that the Bethe-Larkin formula for the energy losses of fast heavy-ion projectiles in dense hydrogen plasmas is corrected by the electron-ion correlations [Phys. Rev. Lett. 101, 075002 (2008)]. We report numerical estimates of this correction based on the values of gei(0) obtained by numerical simulations in [Phys. Rev. E 61, 3470 (2000)]. We also extend this result to...

OBJECTIVES To determine whether erosive osteoarthritis shares the same pattern of joint involvement and risk profile as increasing grades of non-erosive hand osteoarthritis. METHODS Participants were from two population-based cohorts, aged ≥50 years, reporting hand symptoms in the previous month. Interphalangeal joints were assessed for erosive osteoarthritis (Verbruggen-Veys erosive or remod...

The authors discuss and demonstrate the feasibility of using ultra wide band microwave radar to detect and identify small arms fire. Detection and tracking is by standard radar techniques, but identification is carried out by exciting the projectiles Complex Natural Resonances and using this aspect independent information to assign a caliber to the incoming projectiles. The typical sizes of sma...

The penetration of low-speed projectiles into a water target has been studied in the last several years to understand the physics behind the formation and collapse of cavities. In such studies, the projectiles employed were solid bodies or liquid drops. Here we report similar impact experiments using granular projectiles, with the aim to investigate how the morphology of the cavities is determi...

background and aims. oral lichen planus is a relatively common chronic oral mucosal disease of unknown etiology. regarding numerous studies on the immunologic factors involved in the etiology of lichen planus, the present study evaluated the serum interleukin-17 (il-17) level in patients with erosive and non-erosive oral lichen planus. materials and methods. this descriptive analytical study in...

The electronic stopping cross sections in boron for atomic projectiles with Z 11 have been determined in the energy interval 15 to 140 keV. Reasonable agreement is found with theory, however the previously observed periodic dependence of SE on the atomic number of the project i le is also evident. Results for the relative straggling in energy loss are reported for hydrogen projectiles in boron,...

background and aims. the clinical management of oral lichen planus poses considerable difficulties to the clinician. in recent years, researchers have focused on the presence of pathogenic microorganisms such as candida albicans in the patients with refractory lichen planus. the aim of the present study was to investigate the prevalence of candida species in the erosive oral lichen planus lesio...

OBJECTIVE The objective of this study was to assess the discriminative power of dual-energy computed tomography (DECT) versus single-energy CT (SECT) to distinguish between ferromagnetic and non-ferromagnetic ballistic projectiles to improve safety regarding magnetic resonance (MR) imaging studies in patients with retained projectiles. MATERIALS AND METHODS Twenty-seven ballistic projectiles ...
