Human telomeres contain at least three types of G-rich repeat distributed non-randomly.
Using a combination of different oligonucleotides and restriction enzymes we have examined the gross organisation of repeats within the most distal region of human chromosomes. We demonstrate here that human telomeres do not contain a pure uniform 6 base pair repeat unit but that there are at least three types of repeat. These three types of repeat are present at the ends of most or all human c...
متن کاملArcs Intersecting at Most Once
We prove that on a punctured oriented surface with Euler characteristic χ < 0, the maximal cardinality of a set of essential simple arcs that are pairwise nonhomotopic and intersecting at most once is 2|χ|(|χ|+1). This gives a cubic estimate in |χ| for a set of curves pairwise intersecting at most once on a closed surface. We also give polynomial estimates in |χ| for sets of arcs and curves pai...
متن کاملOn Existing All at Once
e nature of divine eternality is obscure in both historical andmodern discussions. In a way its obscurity is no surprise, given that the nature of time is so mysterious. But the obscurity is still notable relative to the other traditional divine attributes, which are comparatively much better understood. Our perplexities regarding eternality are compounded, I will argue here, by a failure to re...
متن کاملm at h . A G ] 1 4 Fe b 20 06 All the GIT quotients at once
Let G be an algebraic torus acting on a smooth variety V . We study the relationship between the various GIT quotients of V and the symplectic quotient of the cotangent bundle of V . Let G be a reductive algebraic group acting on a smooth variety V . The cotangent bundle T V admits a canonical algebraic symplectic structure, and the induced action of G on T V is hamiltonian, that is, it admits ...
متن کاملContamination of laryngoscope handles.
Despite use of sterile or disposable laryngoscope blades for each patient, disinfection of laryngoscope handles does not routinely occur, and these devices present a potential route of transmission of pathogens between patients and staff. A total of 192 specimens from 64 laryngoscope handles deemed 'ready for patient use' in the anaesthetic rooms of 32 operating theatres were semiquantitatively...
