We focus on the development of new silicate phosphors for a white LED. In the europium doped silicate system, four LED phosphor candidates—Li2SrSiO4:Eu, Ba9Sc2Si6O24:Eu, Ca3Si2O7:Eu and Ba2MgSi2O7:Eu were found. Luminescent properties under near UV and visible excitation were investigated for the new Eu2+ doped LED silicate phosphors. These new phosphors have a relatively strong absorption band...

The crystalline form of 1-deoxy-D-tagatose, C6H12O5, is shown to be 1-deoxy-alpha-D-tagatopyranose; the absolute configuration is determined by use of D-lyxono-1,4-lactone as the starting material. The title compound crystallized as concomitant polymorphs from a mixture of ethyl actate and methanol. Although the melting points of the materials differ by 7 K, the molecular conformations are almo...

INTRODUCTION Septilin is an Ayurvedic preparation which contains antibacterial and anti-inflammatory principles. Septilin has been reported to stimulate phagocytosis. Cahu and Hirsh (1960) demonstrated the presence of an antibacterial protein (phagocytin) in the cytoplasmic granules of polymorphs. This protein of polymorphs has an antibacterial effect on both gram-positive and gram-negative org...

At 70 h of age, the neonate presented with diarrhea. Examination revealed an active infant with normal hydration. Investigations revealed: hemoglobin 17 g/dl; TLC 8,300/mm (60% polymorphs, 40% lymphocytes and band to total neutrophil count ratio of 0.33); micro ESR 1 mm/lst hour. Stool miscroscopy revealed numerous polymorphs. Blood culture was sterile and stool culture grew Escherichia coli se...

Aluminium is a potent neurotoxin and has been associated with Alzheimer's disease (AD) causality for decades. Prolonged aluminium exposure induces oxidative stress and increases amyloid beta levels in vivo. Current treatment modalities for AD provide only symptomatic relief thus necessitating the development of new drugs with fewer side effects. The aim of the study was to demonstrate the prote...

Dozens of proteins are known to convert to the aggregated amyloid state. These include fibrils associated with systemic and neurodegenerative diseases and cancer, functional amyloid fibrils in microorganisms and animals, and many denatured proteins. Amyloid fibrils can be much more stable than other protein assemblies. In contrast to globular proteins, a single protein sequence can aggregate in...

The fine structure of collagen fibrils at sites of antigen-antibody interaction is described. Following injection of antigen (BSA or ferritin) into the center of the cornea of hyperimmune rabbits, an acidophilic ring of precipitate forms at the periphery of the cornea, where antigen and antibody interact in optimal proportions. The precipitate is soon removed by infiltrating polymorphs, but per...

Five Bacteroides fragilis strains and five Bacteroides vulgatus strains were compared with regard to their ability to consume complement and to fix C3, their killing by polymorphonuclear leucocytes, and their ability to inhibit the bactericidal effect of serum and polymorphs on Escherichia coli strains. Complement consumption was positively related to C3 fixation, but no relation was observed b...

The two most common polymorphs in industrial alite, $M_1$ and $M_3$, were characterized at the molecular scale. Different methods employed discussed to assess mechanical properties specific heat of both polymorphs. calculated homogenized elastic moduli found good agreement with experimental measurements. A comparative analysis spacial Young's modulus reveal isotropic anisotropic distribution fo...
