Research on the compression algorithm of the infrared thermal image sequence based on differential evolution and double exponential decay model.

This paper has proposed a new thermal wave image sequence compression algorithm by combining double exponential decay fitting model and differential evolution algorithm. This study benchmarked fitting compression results and precision of the proposed method was benchmarked to that of the traditional methods via experiment; it investigated the fitting compression performance under the long time series and improved model and validated the algorithm by practical thermal image sequence compression and reconstruction. The results show that the proposed algorithm is a fast and highly precise infrared image data processing method.

Molecular cloning and characterization of a rice blast-inducible RING-H2 type zinc finger gene.

A novel blast-inducible RING-H2 type zinc finger protein gene OsRING-1 was cloned from rice by cDNA library screening. OsRING-1 is 1670 bp in length and encodes a 46.6 kDa basic protein with two transmembrane (TM) domains, a basic domain (BD), a conserved domain (CD), a RING finger domain and a serine rich (S-rich) domain.

[Mechanism of G2/M cell cycle arrest before apoptosis in leukemia cell line HL-60 induced by proteasome inhibitor MG132].

Background & Objective: Proteasome inhibitor is a kind of potential anti-tumor drug,it can induce apoptosis in various tumor cells. This study was designed to investigate the molecular mechanism of apoptosis and G(2)/M arrest in leukemia cell line HL-60 induced by proteasome inhibitor MG132 (Z-Leu-Leu-Leu-CHO).

Methods: Apoptosis in HL-60 cells was observed under fluorescent microscope, flow cytometry and immunoblot were used to analyze cell apoptosis, cell cycle arrest, and the mechanisms.
