Transmissible spongiform encephalopathies (TSEs) are neurological disorders that include genetic, infectious and sporadic forms of human Creutzfeldt-Jakob disease (CJD). The pathogenic agent is the prion protein that is composed of an abnormal isoform (PrP(Sc)) of a host-encoded protein (PrP(C)). Analysis of the relative amounts of PrP(Sc) glycoforms has… (More)

A closed κ 0-curve is a closed regular curve of class C r (r ≥ 2) in the Euclidean 3-space having constant curvature κ 0 > 0. We present various examples of nonplanar closed κ 0-curves of class C 2 , which are composed of n arcs of circular helices. The construction of c starts from the spherical image (= tangent indicatrix) c of c, which then has to be a… (More)

We evaluated the brain of a 4-month-old male infant whose mother had inadequately controlled maternal phenylketonuria (MPKU). At autopsy his brain was normally developed but underweight. We found ventriculomegaly, hypoplastic cerebral white matter, and delay of myelination in late myelinating tracts without white matter astrocytosis and without chronic… (More)

AS-regular algebras of global dimension n were defined in [3] as non-commutative analogues of the polynomial algebra on n-variables. An AS-regular algebra A is a finitely generated connected N-graded k-algebra. It has a presentation as T (V *)/I where T (V *) is the tensor algebra on a finite-dimensional vector space V * and I is a homogeneous ideal. The… (More)
