Factorization of the Abel-Jacobi maps
As an application of the theory of Lawson homology and morphic cohomology,
Walker proved that the Abel-Jacobi map factors through another regular
homomorphism. In this note, we give a direct proof of the theorem.Comment: 9 pages, comments are welcome, published versio
Two coniveau filtrations and algebraic equivalence over finite fields
We extend the basic theory of the coniveau and strong coniveau filtrations to
the -adic setting. By adapting the examples of Benoist--Ottem to the
-adic context, we show that the two filtrations differ over any
algebraically closed field of characteristic not .
When the base field is finite, we show that the equality of the
two filtrations over the algebraic closure has some
consequences for algebraic equivalence for codimension- cycles over
. As an application, we prove that the third unramified cohomology
group vanishes for a
large class of rationally chain connected threefolds over ,
confirming a conjecture of Colliot-Th\'el\`ene and Kahn.Comment: 30 pages, comments are welcome. This is an expanded version of the

Re-calibration of SDF/SXDS Photometric Catalogs of Suprime-Cam with SDSS Data Release 8
We present photometric recalibration of the Subaru Deep Field (SDF) and
Subaru/XMM-Newton Deep Survey (SXDS). Recently, Yamanoi et al. (2012) suggested
the existence of a discrepancy between the SDF and SXDS catalogs. We have used
the Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8) catalog and compared
stars in common between SDF/SXDS and SDSS. We confirmed that there exists a
0.12 mag offset in B-band between the SDF and SXDS catalogs. Moreover, we found
that significant zero point offsets in i-band (~ 0.10 mag) and z-band (~ 0.14
mag) need to be introduced to the SDF/SXDS catalogs to make it consistent with
the SDSS catalog. We report the measured zero point offsets of five filter
bands of SDF/SXDS catalogs. We studied the potential cause of these offsets,
but the origins are yet to be understood.Comment: 36 pages, 19 figures(128 EPS files), PASJ accepte
The Representative Porcine Model for Human Cardiovascular Disease
To improve human health, scientific discoveries must be translated into practical applications. Inherent in the development of these technologies is the role of preclinical testing using animal models. Although significant insight into the molecular and cellular basis has come from small animal models, significant differences exist with regard to cardiovascular characteristics between these models and humans. Therefore, large animal models are essential to develop the discoveries from murine models into clinical therapies and interventions.
This paper will provide an overview of the more frequently used large animal models, especially porcine models for preclinical studies
Purification of functional baculovirus particles from silkworm larval hemolymph and their use as nanoparticles for the detection of human prorenin receptor (PRR) binding
<p>Abstract</p> <p>Background</p> <p>Baculovirus, which has a width of 40 nm and a length of 250-300 nm, can display functional peptides, receptors and antigens on its surface by their fusion with a baculovirus envelop protein, GP64. In addition, some transmembrane proteins can be displayed without GP64 fusion, using the native transmembrane domains of the baculovirus. We used this functionality to display human prorenin receptor fused with GFP<sub>uv </sub>(GFP<sub>uv</sub>-hPRR) on the surface of silkworm <it>Bombyx mori </it>nucleopolyhedrovirus (BmNPV) and then tested whether these baculovirus particles could be used to detect protein-protein interactions.</p> <p>Results</p> <p>BmNPV displaying GFP<sub>uv</sub>-hPRR (BmNPV-GFP<sub>uv</sub>-hPRR) was purified from hemolymph by using Sephacryl S-1000 column chromatography in the presence of 0.01% Triton X-100. Its recovery was 86% and the final baculovirus particles number was 4.98 × 10<sup>8 </sup>pfu. Based on the results of enzyme-linked immunosorbent assay (ELISA), 3.1% of the total proteins in BmNPV-GFP<sub>uv</sub>-hPRR were GFP<sub>uv</sub>-hPRR. This value was similar to that calculated from the result of western blot by a densitometry (2.7%). To determine whether BmNPV-GFP<sub>uv</sub>-hPRR particles were bound to human prorenin, ELISA results were compared with those from ELISAs using protease negative BmNPV displaying β1,3-<it>N</it>-acetylglucosaminyltransferase 2 fused with the gene encoding GFP<sub>uv </sub>(GGT2) (BmNPV-<it>CP</it><sup>-</sup>-GGT2) particles, which do not display hPRR on their surfaces.</p> <p>Conclusion</p> <p>The display of on the surface of the BmNPV particles will be useful for the detection of protein-protein interactions and the screening of inhibitors and drugs in their roles as nanobioparticles.</p
