Histone modifications are important markers of function and chromatin state, yet the DNA sequence elements that direct them to specific genomic locations are poorly understood. Here, we identify hundreds of quantitative trait loci, genome-wide, that affect histone modification or RNA polymerase II (Pol II) occupancy in Yoruba lymphoblastoid cell lines (LCLs). In many cases, the same variant is ...

hirchsprung’s disease is a developmental disorder of the enteric nervous system, characterized by abdsence of ganglion cell in the myenterric and submucosal plexuese along a variable portion of the distal intestine.the purpose of this study is the presentation of a new procedure for reduction of the postoperative complications of hirschsprung’s disease (hd) by offering a modified swenson’s tech...

background: visceral leishmaniasis is systematic serous parasitic disease with pub­lic health importance. zoonotic form of visceral leishmaniasis is wide spread in mediterranean basin and south america regions. direct agglutination test (dat) is an accurate, reliable and non-expensive serological test for the diagnosis of visceral leishmaniasis in human and canines but the antigen preparation i...

chromium (vi) adsorption behavior and capacity by surface modified nanozeolite a has been investigated. surface modification was performed and the morphology of modified and unmodified nanozeolite was studied using scanning electron microscope (sem) and transmission electron microscope (tem). adsorption isotherms were studied under different conditions (ph, adsorbent dose, adsorbate concentrati...

this paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. among common magnetic nanoparticles, magnetite (fe3o4) and maghemite (g-fe203) are popular candidates because of their biocompatibility. natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...

The effect of starch granule sizes, shapes, composition, and frequency on the dielectric properties (dielectric constant, loss factor, conductivity) native hydrothermally modified starches (potato, corn, rice starch) are investigated in this work. Dielectric determined from 5 Hz to GHz. exhibit lower than GHz due disruption polysaccharide’s molecular arrangement. potato shows highest factor (20...
