Via Study’s kinematic mapping S the 6-parametric Lie group SE(3) of direct Euclidean displacements can be identified with a certain hyperquadric M6 in 7-dimensional real projective space. The mapping has nice geometric properties; for instance one parametric rotation groups are represented by straight lines on M6, coordinate transformations in Euclidean 3-space are represented by special automo...

background:alpha-synuclein is a member of synuclein family of proteins with unidentified function localized in the cytoplasm, mitochondria of neurons, and presynaptic nerve endings. although it is found in the lewy bodies in synucleinopathies and in alzheimer’s disease, the protein could also be considered as a novel marker in diagnosis of diseases related to the hematopoietic system. methods: ...

Lancaster General Health is the first institution in the United States to have the next generation CyberKnife made by Accuray Inc., the M6 series (Fig. 1). The CyberKnife utilizes non-invasive stereotactic radiosurgery to deliver precise, high doses of radiation to targets anywhere in the body. Recent studies have shown that stereotactic radiosurgery offers high rates of tumor control with mini...

An M28-derived group A streptococcal strain deleted for the gene encoding M protein was converted to M+ by introduction of a plasmid carrying emm6, the structural gene for type 6 M protein from strain D471. The reconstituted M+ strain, JRS2, resists phagocytosis in human blood and is opsonized by anti-M6 hyperimmune serum, but not by anti-M28 serum. Immunofluorescent microscopy and ELISA demons...

Probes from the m6 homeo box cluster were mapped to mouse chromosome 6 by somatic cell genetics, in situ hybridisation, and by a Mus spretus--Mus musculus backcross mapping system. In addition, the testis-specific homeo box containing cDNA, clone, HBT-1, has been mapped using the same back-cross system and the B X D recombinant inbred strain set. Close genetic and physical linkage between the m...

PMR1 is the yeast secretory pathway pump responsible for high affinity transport of Mn2+ and Ca2+ into the Golgi, where these ions are sequestered and effectively removed from the cytoplasm. Phenotypic growth assays allow for convenient screening of side chains important for Ca2+ and Mn2+ transport. Earlier we demonstrated that mutant Q783A at the cytoplasmic interface of M6 could transport Ca2...

The effect of mixtures of antioxidants butylated hydroxyanisol (BHA) and propyl paraben (PP) on lag phase, growth rate and ochratoxin A (OTA) production by four Aspergillus section Nigri strains was evaluated on peanut meal extract agar (PMEA) under different water activities (a(w)). The antioxidant mixtures used were: BHA + PP (mM), M1 (0.5 + 0.5), M2 (1.0 + 0.5), M3 (2.5 + 0.5), M4 (0.5 + 1.0...

M6 protein of Streptococcus pyogenes binds directly to HEp-2 cell surfaces and helps to mediate bacterial adhesion. Two epithelial cell receptors for M protein were identified as 97- and 205-kDa glycoproteins. Purified recombinant M6 protein (rM6) showed a dose-dependent and saturable binding to isolated HEp-2 membranes in an enzyme immunoassay. The HEp-2 cell receptors were selectively denatur...

BACKGROUND Gammaherpesviruses cause important infections of humans, in particular in immunocompromised patients. The genomes of gammaherpesviruses contain variable numbers of internal repeats whose precise role for in vivo pathogenesis is not well understood. METHODOLOGY/PRINCIPAL FINDINGS We used infection of laboratory mice with murine gammaherpesvirus 68 (MHV-68) to explore the biological ...
