We present a solution to the problem of performing approximate pattern matching on compressed text. The format we choose is the Ziv-Lempel family, speciically the LZ78 and LZW variants. Given a text of length u compressed into length n, and a pattern of length m, we report all the R occurrences of the pattern in the text allowing up to k insertions, deletions and substitutions, in O(mkn + R) ti...

In this work we present the observation of the Mkn 463 field performed with the MECS instrument on– board BeppoSAX in the 1.8–10.5 keV band. The Mkn 463 field is an example of an extragalactic field crowded with absorbed X–ray sources: apart from the Seyfert 2 galaxy Mkn 463 and the well known QSO PG 1352+183 (the only object showing no absorption), two other objects are detected with a column ...

The CAT (Cerenkov Array at Thémis) γ-ray detector 1 operates above 250 GeV since Autumn 1996. Its observation program has been largely devoted to the study of blazars. These objects are radio-loud active galactic nuclei (AGN’s) with a relativistic jet which is pointed directly to the observer. The jet emission dominates that of the accretion disk (and of the host galaxy) over a large energy dom...

The recent HEGRA observations of the blazar Mkn 501 show strong curvature in the very high energy γ-ray spectrum. Applying the γ-ray opacity derived from an empirically based model of the intergalactic infrared background radiation field (IIRF), to these observations, we find that the intrinsic spectrum of this source is consistent with a power-law: dNγ/dE ∝ E −α with α = 2.00 ± 0.03 over the r...

DNA-binding protein inhibitor ID-1 (ID1) serves an essential role in tumor progression, and the self-renewal and pluripotency of embryonic stem cells. However, the effect of ID1 on the stemness and cancer stem cell (CSC)-like properties of gastric adenocarcinoma cells remains to be elucidated. In the present study, effective ID1 knockdown was achieved in gastric cancer (GC) cells using small in...

A mouse gastric cancer model is an important tool for studying the mechanisms of gastric cancer. To establish subcutaneously implanted tumors, MKN-45 cell suspensions and tumor tissues were implanted into the middle of the right armpit of nude mice. To generate an abdominal metastasis model, MKN-45 cell suspensions and tumor tissue homogenates were implanted into the middle of the lower abdomen...

OBJECTIVE To evaluate the effects of Rhizoma kaempferiae volatile oil on tumor growth and cell cycle of MKN-45 human gastric cancer cells orthotopically transplanted in nude mice. METHODS One hundred and five nude mice orthotopically transplanted with MKN-45 human gastric cancer cells were randomly divided into seven groups: untreated group, normal saline-treated group, dissolvant-treated gro...

New observations are reported of J-band spectra (1.04 μm – 1.4 μm) of three Seyfert 2 galaxies, Mkn 34, Mkn 78 and NGC 5929. In each case the spectral range includes the near-infrared lines of [Feii], [Pii], Hei and Paβ. Each Seyfert galaxy has a known radio jet, and we investigate the infrared line ratios of the nuclear and extended regions of each galaxy compared to the radio structure. In Mk...

Identification of novel tumor-related antigens and autoantibodies will lead to early diagnosis of cancer and the development of more effective immunotherapies. The purpose of this study was to identify novel tumor antigens from the gastric cancer cell lines MkN-1, MkN-45 and KATOIII, and their related autoantibodies in sera of patients with gastric cancer using a proteomics-based approach. Prot...

Cysteine-rich protein 61 (CYR61) is a member of the CCN (CYR61/CTGF/NOV) family, which is associated with progression in a variety of human cancers. Our previous study confirmed that the expression levels of CYR61 protein were decreased in gastric carcinoma compared to non-tumoral mucosa as determined by proteome analysis. Histological research also showed that the reduction in CYR61 expression...
