In this paper, an approach of principal component analysis (PCA) with local pixel grouping (LPG) is used to de-noising the noisy historical document image. This technique ensures the preservation of historic document image local structure. This is due to block matching based LPG which carries out classification to allow only the sample blocks with similar contents used in the calculation for PC...

BACKGROUND/AIMS Lipoprotein glomerulopathy (LPG) is a rare hereditary disease. In this study, we investigated the apoE mutation and the role of double filtration plasmapheresis therapy (DFPP) on a new Chinese patient with LPG. METHODS Renal biopsy was performed on this patient to allow a definitive diagnosis. The mutations in the coding sequence of apoE and the hereditary pedigree of this pat...

Lipoprotein glomerulopathy (LPG) is characterized by the accumulation of lipoprotein thrombi within glomerular capillaries. This rare disorder is associated with various types of mutations in the apolipoprotein E gene (apoE). Herein, we present a case of LPG with a combination of apoE Chicago (Arg147Pro) and apoE (Glu3Lys) mutations. A 51-year-old Japanese woman presented with severe (3+) prote...

At key steps in the infectious cycle pathogens must adhere to target cells, but at other times detachment is required for transmission. During sand fly infections by the protozoan parasite Leishmania major, binding of replicating promastigotes is mediated by galactosyl side chain (scGal) modifications of phosphoglycan repeats of the major surface adhesin, lipophosphoglycan (LPG). Release is med...

In this paper, the effects of temperature on the spectral profiles of long period grating (LPG) fabricated in BGe co doped photosensitive fiber is investigated. The results obtained show that LPG in a B–Ge co doped fiber has negative temperature response or opposite sign of the temperature dependence compared with LPG written in standard telecommunication fiber . Keywords— Fiber grating, Long P...

Lipophosphoglycan (LPG), a surface glycoconjugate of Leishmania promastigotes, has been reported as playing an active role in protecting the parasite within phagolysosomes, by an impairment of monocyte oxidative responses. In this study the effect of LPG on the oxidative burst of human peripheral monocytes, eosinophils and neutrophils was evaluated. Our results demonstrated that either superoxi...

In this paper, we explore the interaction between taxation and local public good (LPG) and how it impacts the spatial pattern in the framework of new economic geography (NEG). In the benchmark case of a pure LPG, the system displays a similar location pattern to the existing NEG taxation model, although the tax reduces the market size of manufactured goods. However, when we consider the inheren...

The life cycle of Leishmania parasites within the sand fly vector includes the development of extracellular promastigotes from a noninfective, procyclic stage into an infective, metacyclic stage that is uniquely adapted for transmission by the fly and survival in the vertebrate host. These adaptations were explored in the context of the structure and function of the abundant surface lipophospho...

The major macromolecule on the surface of the protozoan parasite Leishmania major is a lipophosphoglycan (LPG) which contains a glycosylphosphatidylinositol glycolipid anchor. This parasite also synthesizes a complex family of abundant low-molecular-mass glycoinositolphospholipids (GIPLs) which are structurally related to the LPG anchor. In this study, L. major promastigotes were metabolically ...

We present two novel schemes for refractometry based on a long-period fiber grating- (LPG-) based Michelson interferometer. These schemes are designed to overcome the measurement dependence of previously demonstrated LPG-based refractometry on the immersion depth. The first utilizes an unshielded LPG and the second, a shielded one. Both schemes were tested over a certain refractive-index range,...
