introduction: over expression of selected peptide receptors in human tumors has been shown to represent clinically relevant targets for cancer diagnosis and therapy. the aim of this work was to investigate neuropeptide y (npy) as a new radiopharmaceutical for diagnosis of breast cancer. methods: a neuropeptide y analogues with y1 receptor preference and agonistic properties was synthesized by s...

On primitive roots of unity, divisors of p 2 − 1, and an extension to mod p Abstract Primitive roots of 1 mod p k (k > 2 and odd prime p) are sought, in cyclic units group G k ≡ A k B k mod p k , coprime to p, of order (p − 1)p k−1. 'Core' subgroup A k has order p − 1 independent of precision k, and 'extension' subgroup B k of all p k−1 residues 1 mod p is generated by p+1. Integer divisors of ...

We construct Spin(p+1, p+1) covariant Dp–brane bound states by using that the potentials in the RR sector of toroidically compactified type II supergravity transform as a chiral spinor of the T–duality group. As an application, we show the invariance of the zero–force condition for a probe D–brane under noncommutative deformations of the background, which gives a holographic proof of the stabil...

a complication in the analysis of the role of icp34.5 gene in the herpes simplex virus type-1 (hsv-1) lifecycle is the presence of overlapping antisense gene, open reading frame p (orf p), which is also deleted in hsv-1 icp34.5 negative mutants. a hsv-1 wild type strain (17+) icp34.5/orf p deletion mutant (1716) is totally avirulent in animal models and impaired in a number of in vitro function...
