Blebbistatin modulates prostatic cell growth and contrapctility through myosin II signaling.

To investigate the effect of blebbistatin (BLEB, a selective myosin inhibitor) on regulating contractility and growth of prostate cells and to provide insight into possible mechanisms associated with these actions. BLEB was incubated with cell lines of BPH-1 and WPMY-1, and intraprostatically injected into rats. Cell growth was determined by flow cytometry, and organ bath studies were performed to explore muscle contractility.

Testosterone regulates myosin II isoforms expression and functional activity in the rat prostate.

Background: Benign prostatic hyperplasia (BPH) is mainly caused by increased prostatic smooth muscle (SM) tone and prostatic volume. At the molecular level, SM myosin II (SMM II) and non-muscle myosin II (NMM II) mediate SM tone and cell proliferation while testosterone (T) plays a permissive role in the development of BPH.

Aims: The novel objective of this study was to elucidate the effects of T on the proliferation and apoptosis of rat prostatic cells and SM contractility as well as related regulatory signaling pathways.

[Research of hyperspectral reconstruction based on HJ1A-CCD data].

By restoring plentiful spectral information from several bands, hyperspectral image reconstruction could provide more suitable data source to water environment remote sensing. This is significant for inland water color remote sensing. By using the HJ1 A-HSI and HJ1A-CCD image acquired on June 6th, 2009, the hyperspectral data was reconstructed from HJ1A-CCD data.

Degradation of 2,6-di-tert-butylphenol by an isolated high-efficiency bacterium strain.

An aerobic bacterium strain, F-3-4, capable of effectively degrading 2, 6-ditert-butylphenol (2, 6-DTBP), was isolated and screened out from an acrylic fiber wastewater and the biofilm in the wastewater treatment facilities. This strain was identified as Alcaligenes sp. through morphological, physiological and biochemical examinations.

[The degradation characteristics of degrading bacterium of 2,6-di-tert-butylphenol].

A degrading bacterial strain F-3-4 for 2,6-Di-tert-butylphenol (2,6-DTBP) was isolated from biofilm in acrylic fiber wastewater treatment structures. By acclimation, its capacity for degradation of 2,6-DTBP was enhanced by 26%. It was identified as Alcaligenes sp.

The Isolation and Purification of Archaerhodopsin from Halobacterium sp. XZ515.

The claret membrane, instead of the purple membrane, was isolated when the conventional method for isolating purple membrane from Halobacterium halobium was applied to Halobacterium sp. XZ515. The SDS-PAGE results showed that only one protein, archaerhodopsin, existed in claret membrane with M.
