Background: Pea seed-borne mosaic virus (PSbMV) is a member of the genus Potyvirus that can be transmitted by seeds, causing serious losses in legume crop yields. Its genome consists of 3 peptidases-P1, HC-Pro, and NIa. Interestingly, only the P1 peptidase, localized on the N-terminal portion of the viral polyprotein, still remains without any concrete function on influencing viral infections. ...

Mycoplasma pneumoniae cytadhesin P1 was purified by monoclonal antibody affinity chromatography followed by preparative sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The N-terminal 18-amino-acid sequence of P1 was determined and used to design two synthetic oligonucleotides, a 14-mer corresponding to amino acids 1 to 5 and an 18-mer corresponding to amino acids 7 to 12. These oligo...

The Constraint Satisfaction Problem (CSP) is a problem of computing a homomorphism R → Γ between two relational structures, where R is defined over a domain V and Γ is defined over a domain D. In fixed template CSPs, denoted CSP(Γ), the right side structure Γ is fixed and the left side structure R is unconstrained. In the last 2 decades it was impressively revealed that reasons that make fixed ...

The notion of P-homomorphic signatures, introduced by Ahn et al. (TCC 2012), generalizes various approaches for public computations on authenticated data. For a given predicate P anyone can derive a signature for a message m′ from the signatures of a set of messages M , as long as P(M,m′) = 1. This definition hence comprises notions and constructions for concrete predicates P such as homomorphi...

Purple eggplant (Solanum melongena L.) is known to contain anthocyanins, which is about 850 mg/kg of eggplant. Anthocyanins are water soluble pigments which the antioxidant ability arising from structural conjugated bonding system, so having a high reactivity as a primary antioxidant, oxygen scavengers, and chelator, that these substances are expected to reduce oxidative stress in diabetes meli...

Two small satellites of Pluto, S/2005 P1 (hereafter P1) and S/2005 P2 (hereafter P2), have recently been discovered outside the orbit of Charon, and their orbits are nearly circular and nearly coplanar with that of Charon. Because the mass ratio of Charon-Pluto is ∼ 0.1, the orbits of P2 and P1 are significantly non-Keplerian even if P2 and P1 have negligible masses. We present an analytic theo...

We show that if Γ is a finitely presented metabelian group, then the “untwisted” fibre product or pull-back P associated to any short exact sequence 1 → N → Γ → Q → 1 is again finitely presented. In contrast, if N and Q are abelian, then the analogous “twisted” fibre-product is not finitely presented unless Γ is polycyclic. Also a number of examples are constructed, including a non-finitely pre...

We reported that an 11 amino acid synthetic peptide (P1) activates lung endothelial cell nitric oxide synthase (eNOS) independent of its change in expression and/or phosphorylation. Since caveolae/eNOS dissociation is known to enhance the catalytic activity of eNOS, we examined whether P1-mediated increase of eNOS activity is associated with caveolae/cholesterol modulation, increased caveolin-1...

To identify determinants of attenuation in the poliovirus type 1 Sabin vaccine strain, a series of recombinant viruses were constructed by using infectious cDNA clones of the virulent type 1 poliovirus P1/Mahoney and the attenuated type 1 vaccine strain P1/Sabin. Intracerebral inoculation of these viruses into transgenic mice which express the human receptor for poliovirus identified regions of...
