Bullous pemphigoid (BP) is an autoimmune bullous disorder with urticarial pruritic papules and plaques and tense bullae in flexural surfaces of body. The localized form of the disease is a rare variant which can be triggered by different stimuli. Hereunder, we report a patient with the local type involving genitalia without any triggering factors.
In this paper, we rigorously derive a diffusion model for semiconductor superlattices, starting from a kinetic description of electron transport at the microscopic scale. Electron transport in the superlattice is modelled by a collisionless Boltzmann equation subject to a periodic array of localized scatters modeling the periodic heterogeneities of the material. The limit of a large number of p...
We propose a phenomenological model for pattern formation in a vertically vibrated layer of granular material. This model exhibits a variety of stable cellular patterns, including standing rolls and squares as well as localized objects (oscillons and worms), similar to recent experimental observations [Umbanhowar, Melo, and Swinney, Nature (London) 382, 793 (1996)]. The model is an amplitude eq...
INTRODUCTION Localized scleroderma is an autoimmune disease primarily affecting the skin. The cause of disease remains unexplained although environmental factors are implicated, which are likely to be responsible for activation of the endothelium and subsequent inflammation leading to excessive synthesis of collagen and extracellular matrix components. AIM To determine concentrations of inter...
Retrospective study of 59 chlidren with JLS from 3 to 17 y (M = 10.3) treated with MTX was performed. Group 1 (n = 18) – received prednisone 0.5 mg\kg for 6 weeks, taped to 0.1 mg\kg for 12 months + MTX 10 mg\body sq. weekly for 13.7 mo. Group 2 (n = 41) -MTX the same doses and duration. The efficacy was measured in 6 & 12 months using skin score, activity and sclerosis indexes (IA, IS) (1 – 3 ...
Developmental transitions and stress reactions in both eukaryotes and prokaryotes are tightly linked with fast and localized modifications in concentrations of reactive oxygen and nitrogen species (ROS and RNS). Fluorescent microscopic analyses are widely applied to detect localized production of ROS and RNS in vivo. In this mini-review we discuss the biological characteristics of studied mater...
BACKGROUND Hepatobiliary tuberculosis includes miliary, tuberculous hepatitis or localized forms. The localised form is extremely uncommon and can mimic malignancy. Still rarer is its presentation as sclerosing cholangitis. CASE PRESENTATION A 50 year male presented with acute onset jaundice, significant weight loss and elevated liver enzymes with clinico-radiological suspicion of cholangioca...
in this paper, the interaction between an oscillating dipole moment and a silver nanoparticle has been studied. our calculations are based on mie scattering theory and discrete dipole approximation(dda) method.at first, the resonance frequency due to excitingthe localized surface plasmons has been obtained using mie scattering theory and then by exciting a dipole moment in theclose proximity of...
We report experiments on piles of cohesionless granular materials showing the effect of construction history on static stress distributions. Stresses under piles are monitored by sensitive capacitive techniques. The piles are formed either by pouring granular material from a funnel with a small outlet (localized source), or from a large sieve (homogeneous rain). Localized sources yield stress p...
We consider a passive optical cavity containing a photonic crystal and a purely absorptive two-level medium. The cavity is driven by a superposition of two coherent beams forming a periodically modulated pump. Using a coupled mode reduction and direct numerical modeling of the full system we demonstrate the existence of bistability between uniformly periodic states, modulational instabilities a...
