background: immune reactions have been reported to be involved in the destruction of retinal ganglion cells (rgcs) in glaucoma. objective: to investigate the role of major histocompatibility complex class i-related chain a and b (mica and micb) molecules in the pathogenesis of glaucoma. methods: aqueous humor and serum samples from 15 glaucoma patients and 45 patients with cataract, undergoing ...

The presence of a water layer on the surface of muscovite mica under ambient conditions is well established. The water molecules are well ordered and seem to be oriented, leading to an icelike monolayer (probably ferroelectric) in epitaxial relation with the mica surface. We have imaged and characterized the height and contact angle of ordered water layer(s) formed by wetting and de-wetting pro...

Enrichment of free mica (i.e. as monomineralic grains) in the fine fraction of crushed rock aggregates affects the quality of the aggregate end product. Granitoid rock from the Svecofennian Province were used as being representative of crushed rock aggregates commonly used for construction purposes. The results reveal a general trend of enrichment of mica for finer fractions. For the coarse gra...

This discussion paper proposes to generalize the notion of Independent Component Analysis (ICA) to the notion of Multidimensional Independent Component Analysis (MICA). We start from the ICA or blind source separation (BSS) model and show that it can be uniquely identified provided it is properly parameterized in terms of one-dimensional subspaces. From this standpoint, the BSS/ICA model is gen...

A 15-cm-diameter helicon source was used at the Plasmadynamics and Electric Propulsion Laboratory at the University of Michigan to simulate the density present in the plasma layer surrounding an atmospheric re-entry vehicle. In order to most closely simulate a re-entering vehicle, a “spacecraft surface” was created with a sheet of mica placed so that the bulk of the plasma would be above it. A ...

T cells with variable region Vä1ãä T cell receptors (TCRs) are distributed throughout the human intestinal epithelium and may function as sentinels that respond to self antigens. The expression of a major histocompatibility complex (MHC) class I-related molecule, MICA, matches this localization. MICA and the closely related MICB were recognized by intestinal epithelial T cells expressing divers...

The effect of humidity treatments on the surface morphology of spin-coated pseudoisocyanine (PIC) dye films on mica was investigated by absorption spectroscopy, fluorescence microscopy, and atomic force microscopy (AFM). We demonstrated that the humidity treatment caused dynamic changes of mesoscopic J aggregate morphology due to the mobile nature of PIC molecules on mica surface. Under dry con...

-The alteration experiments of phlogopite with 0.01 N HC1 solution containing 0.1 M NaC1 at 50*, 80* and 120"C have been carried out to aid in the understanding of the dissolution process of mica and the formation of secondary phases such as vermiculite and interstratified mica/vermiculite. Twenty milligrams of phlogopite samples were suspended in 20 ml or 100 ml of leaching solution. In these ...

The YNT1 gene encoding the nitrate transporter in the yeast Hansenula polymorpha is clustered with genes YNI1 and YNR1 encoding nitrite reductase and nitrate reductase, and its disruption causes inability to grow in nitrate M.
