[Characterization of Reductive Dechlorination of Chlorinated Ethylenes by Anaerobic Consortium].

Tetrachloroethylene （PCE） and trichloroethylene （TCE） are typical volatile halogenated organic compounds in groundwater that pose serious threats to the ecological environment and human health. To obtain an anaerobic microbial consortium capable of efficiently dechlorinating PCE and TCE to a non-toxic end product and to explore its potential in treating contaminated groundwater， an anaerobic microbial consortium W-1 that completely dechlorinated PCE and TCE to ethylene was obtained by repeatedly feeding PCE or TCE into the contaminated groundwater collected from an industrial site. The dechlorination rates of PCE and TCE were （120.

Rhizobium flavescens sp. nov., Isolated from a Chlorothalonil-Contaminated Soil.

A Gram-negative, facultative anaerobic, non-lagellated and rod-shaped bacterium FML-4 was isolated from a chlorothalonil-contaminated soil in Nanjing, China. Phylogenetic analyses of 16S rRNA genes revealed that the strain FML-4 shared the highest sequence similarity of 97.1% with Ciceribacter thiooxidans KCTC 52231, followed by Rhizobium rosettiformans CCM 7583 (97.

First principles calculation of the nonhydrostatic effects on structure and Raman frequency of 3C-SiC.

For understanding the quantitative effect of nonhydrostatic stress on properties of material, the crystal structure and Raman spectra of 3C-SiC under hydrostatic and nonhydrostatic stress were calculated using a first-principles method. The results show that the lattice constants (a, b, and c) under nonhydrostatic stresses deviate those under hydrostatic stress. The differences of the lattice constants under hydrostatic stress from nonhydrostatic stresses with differential stress were fitted by linear equation.

[Clinicopathologic characteristics of basal cell carcinoma of the prostate: analysis of 5 cases and review of the literature].

Objective: To investigate the histogenesis, clinicopathologic characteristics, pathologic diagnosis, differential diagnosis, treatment and prognosis of basal cell carcinoma of the Prostate (BCCP).

Methods: We conducted clinicopathologic analysis on the manifestations of 5 cases of BCCP by HE staining and immunohistochemistry and reviewed relevant literature.

Results: Microscopically, the tumor cells were small in volume with ovoid karyomegaly and mitosis, some arranged like a solid nest or with a cribriform appearance.

[Studies of flowering genes of plants].

Plant flower can be divided into two phases--from stem apex meristem tissue into flower meristem tissue and floral apparatus. The flower time genes control the flower development and the homologous genes control flower apparatus identify. This paper summarizes recent studies on plant flower and emphasizes on the first phase flower control genes, theirs interaction and function,characteristic of the homologous genes.
