We analyzed the spectroscopic and photometric database of the 5th data release of the Sloan Digital Sky Survey (SDSS) to search for evidence of the quasar reddening produced by dust embedded in intervening damped Lyα (DLA) systems. From a list of 5164 quasars in the interval of emission redshift 2.25 ≤ ze ≤ 3.5 and SDSS spectra with signal-to-noise ratio SNR ∼ 4, we built up an “absorption samp...

Pemphigus vulgaris (PV) is an acquired autoimmune blistering disease characterized by the production of autoantibodies targeting desmosomal cadherins, primarily desmoglein 1 and 3, leading to acantholysis. The etiology PV multifactorial, including genetic susceptibility. This retrospective study aimed evaluate association HLA class II alleles examine impact PV-associated on concentration anti-d...

The role of abrin, a toxic lectin isolated from seeds of Abrus precatorius Linn in inducing apoptosis in murine Dalton's Lymphoma Ascites (DLA) cells was evaluated. Abrin when incubated at the concentration of 10 ng per million DLA cells could bring about cell death as typical morphological changes with apoptosis. However, necrotic cell death dominated when a higher dose of abrin was used. DNA ...

We extend the conformal mapping approach elaborated for the radial Diffusion Limited Aggregation model (DLA) to the cylindrical geometry. We introduce in particular a complex function which allows to grow a cylindrical cluster using as intermediate step a radial aggregate. The grown aggregate exhibits the same selfaffine features of the original cylindrical DLA. The specific choice of the trans...

Efforts by numerous institutions have been ongoing over the past decade to develop a Dielectric-Loaded Accelerating (DLA) structure capable of supporting high gradient acceleration when driven by an external rf source. Multipactor is the major issue limiting the gradient that was revealed in earlier experiments. A theoretical model predicts a solenoid field within an optimal range of field stre...

We examine the ‘rate-of-incidence’ distribution for damped Lyman-α absorbers (DLAs) as a function of halo mass, galaxy apparent magnitude, and impact parameter using a series of cosmological Smoothed Particle Hydrodynamics (SPH) simulations. Our simulations include radiative cooling and heating by a UV background, star formation, and feedback from supernovae and galactic winds. We find the DLA ...

the association of hla class ii genes with ulcerative colitis (uc) as an autoimmune disease has been investigated for several years. however, factors responsible for genetic predisposition of this disease have so far not been clearly understood. in this study, for the first time, we aimed to investigate the association between hla-drb1 types and uc in the population of kerman, a city southeast ...

OBJECTIVES To analyze the role of HLA genotypes in persistence of chronic hepatitis B in Western India. METHODS HLA genotyping for class II-DR was done in 26 subjects having chronic hepatitis B infection (HBsAg positive) and in 100 healthy controls. Statistics were done using Halden's modification of Woolf's formula. RESULT Significant association of chronic hepatitis B infection was found ...

BACKGROUND Published studies on the association between HLA class II genes and inflammatory bowel disease are contradictory perhaps because of the limited size and ethnic heterogeneity of the populations studied. AIM To compare the frequencies of HLA class II genes in a large number of French patients with Crohn's disease and in an ethnically matched control group. METHODS 344 patients (196...

The aim of this study was to examine frequencies and haplotypic associations of HLA class II alleles in autochthonous population of Gorski kotar (Croatia). HLA-DRB1, -DQA1 and -DQB1 alleles were determined by DNA based PCR typing in 63 unrelated inhabitants from Gorski kotar whose parents and ancestors were born and lived in tested area for at least over four generations. A total of 13 HLA-DRB1...
