The highly peaked, wide-tailed pdfs that are encountered in many image coding algorithms are often modeled using the family of generalized Gaussian (GG) pdfs. We study entropy coding of quantized GG sources using preex codes that are highly structured, and which therefore involve low computational complexity to utilize. We provide bounds for the redundancy associated with applying these codes t...

Herpes simplex virus (HSV) codes for several envelope glycoproteins, including glycoprotein G-2 (gG-2) of HSV type 2 (HSV-2), which are dispensable for replication in cell culture. However, clinical isolates which are deficient in such proteins occur rarely. We describe here five clinical HSV-2 isolates which were found to be unreactive to a panel of anti-gG-2 monoclonal antibodies and therefor...

A radioirnmunoassay for SP1 (“pregnancy-specific” beta1-glycoprotein) is described in which a sensitivity of 0.1 tg/L was achieved by use of an antiserum with Ka 1.7 X lOll L/mol and delayed addition of a 1251-SP1tracer (specific acty, 25 Ci/g) that was stable for use in the assay for at least six to seven weeks. We also report an additional anti-SP serum, from an early bleeding, that displayed...

OBJECTIVE The aim of the present study was to investigate whether there was any relationship between some DNA N-methyltransferase 1 (DNMT1) polymorphisms and susceptibility to idiopathic sudden sensorineural hearing loss (ISSHL) in ISSHL patients. MATERIAL AND METHODS We investigated 90 patients diagnosed with ISSHL and a control group composed of 75 age- and gender-matched healthy individual...

The Differential equation method: calculation of vertex-type diagrams with one non-zero mass Abstract The differential equation method is applied to evaluate analytically two-loop vertex Feynman diagrams. Three on-shell infrared divergent planar two-loop diagrams with zero thresholds contributing to the processes Z → bb (for zero b mass) and/or H → gg are calculated in order to demonstrate a ne...

Glycoprotein G (gG) of alphaherpesviruses has been described to function as a viral chemokine binding protein (vCKBP). More recently, mutant viruses devoid of gG have been shown to result in increased virulence, but it remained unclear if gG's potential to serve as a vCKBP is responsible for this observation. We here used equine herpesvirus type 1 (EHV-1) as a model to study the pathophysiologi...

Based on a variety of recent findings, the Grueneberg ganglion (GG) in the vestibule of the nasal cavity is considered as an olfactory compartment. However, defined chemical substances that activate GG neurons have not been identified. In this study, the responsiveness of murine GG cells to odorants was examined by monitoring the expression of the activity-dependent gene c-Fos. Testing a number...

During infection of a new host, the first surfaces encountered by herpes simplex viruses are the apical membranes of epithelial cells of mucosal surfaces. These cells are highly polarized, and the protein composition of their apical and basolateral membranes are very different, so that different viral entry pathways have evolved for each surface. To determine whether the viral glycoprotein G (g...
