We classify all pencils on a general weighted hypersurface of degree ∑ 4 i=1 ai in P(1, a1, a2, a3, a4) whose general members are surfaces of Kodaira dimension zero.

We classify birational maps into elliptic fibrations of a general quasismooth hypersurface in P(1, a1, a2, a3, a4) of degree ∑ 4 i=1 ai that has terminal singularities.

A family of genes has been identified that encodes subunits of nicotinic acetylcholine receptors (nAChRs) and is expressed in the nervous system. Functional neuronal nAChRs can be expressed in Xenopus oocytes by injection of RNA encoding 1 of 2 different &subunits (/32,84) in pairwise combination with RNA encoding 1 of 3 different a-subunits (a2, (~3, a4). We examined the sensitivity of these 6...

BACKGROUND The critical fatty acids Docosahexaenoic Acid (DHA) and Arachidonic Acid (AA) decline in preterm infants within the first postnatal week and are associated with neonatal morbidities, including bronchopulmonary dysplasia (BPD). DHA and AA are precursors to downstream metabolites that terminate the inflammatory response. We hypothesized that treatment with Resolvin D1 and/or Lipoxin A4...

The aim of this study was to investigate the proteolytic processing of the amyloid precursor protein (APP) in polarized primary cultures of hippocampal neurons. We have used the Semliki Forest virus (SFV) vector to express human APP695 in hippocampal neurons, sympathetic ganglia, and glial cells. The latter two cells secrete little or no APP, whereas hippocampal neurons secrete two forms of APP...

BACKGROUND Ephrin receptors (Ephs) are frequently overexpressed in a wide variety of human malignant tumors, being associated with tumor growth, invasion, metastasis and angiogenesis. The aim of the present study was to evaluate the clinical significance of Eph-A2 and Eph-A4 expression in human benign and malignant thyroid lesions. MATERIAL/METHODS Eph-A2 and Eph-A4 protein expression was ass...

BACKGROUND Sera of patients with coeliac disease, containing IgA and IgG antigliadin antibodies (AGA) and various IgA autoantibodies, react with isolated enterocytes. AGA cross react with enterocyte antigens, one of which has been identified as calreticulin. AIMS To characterise the antigenic structures of gliadin, enterocytes, and calreticulin recognised by AGA from patients with active coel...

The coincidence site lattices of the root lattice A4 are considered, and the statistics of the corresponding coincidence rotations according to their indices is expressed in terms of a Dirichlet series generating function. This is possible via an embedding of A4 into the icosian ring with its rich arithmetic structure, which recently [6] led to the classification of the similar sublattices of A...
