Background & Aims: Alzheimer's disease is a neurodegenerative disorder characterized by the abnormal aggregation of amyloid-β plaques in the brain. Although several studies have been done for finding effective medicines in the treatment of this disease, a drug that inhibits amyloid β aggregation and ameliorates the disorder has not been approved so far. One important therapeutic approach is use...

Polymorphonuclear leukocytes (PMNs) can be divided into Gr-1(high) and Gr-1(low) subpopulations, but the differences in the functions of these cells in the host are unknown. This study investigated the roles of these two cell populations in the clearance of an intracellular pathogen (Haemophilus influenzae) causing murine peritonitis and pneumonia. Microarray analysis and quantitative real-time...

in order to increase the water content and the oxygen permeability of hydrogels used in themanufacture of contact lenses, the polar monomer silicon hydrogel contact lenses (shcl), and 2-hydroxyethyl methacrylate (hema) were copolymerized with the hydrogels. due to the presence ofpolar monomers in the conventional contact lenses, the major component of the human tear,lysozyme is extensively adso...

Neonatal maternal separation alters learning and memory. Glucocorticoids also modulate adult learning and memory, and neonatal maternal separation alters forebrain glucocorticoid receptor (GR) concentrations. We used eyeblink classical conditioning to assess the effect of neonatal maternal separation on associative learning. We assessed delay eyeblink conditioning, GR expression, and total neur...

Chatterjee, B. R. (Baylor University College of Medicine, Houston, Tex.), and Robert P. Williams. Formation of spheroplasts from Bacillus anthracis. J. Bacteriol. 89:1128-1133. 1965.-Spheroplasts were prepared from Bacillus anthracis by combined treatment with lysozyme and glycine. Glycine, at a final concentration of 3%, was added to cultures of B. anthracis in nutrient broth that had grown at...

Lysozyme is increasingly expressed in macrophages in inflammatory response to bacterial LPS. In this study, we investigated the mechanisms that control expression of the lysozyme gene in myelomonocytic HD11 cells activated by LPS. Nuclear run-on transcription assays showed that LPS caused a 15-fold increase in the transcription rate of the lysozyme gene. However, Northern analyses with lysozyme...

The current study examined whether alterations in glucocorticoid receptor (GR) binding contribute to poor response to glucocorticoid therapy in asthma. 29 asthma patients with forced expiratory volume in 1 s (FEV1) < 70% predicted were studied. Patients were classified as steroid sensitive (SS) if their morning FEVI increased > 30% after a I-wk course of oral prednisone 20 mg twice daily and st...
