We propose module graphical lasso (MGL), an aggressive dimensionality reduction and network estimation technique for a highdimensional Gaussian graphical model (GGM). MGL achieves scalability, interpretability and robustness by exploiting the modularity property of many real-world networks. Variables are organized into tightly coupled modules and a graph structure is estimated to determine the ...

Salvia leriifolia (Lamiaceae) is an endemic endangered plant of Khorasan and Semnan province from Iran. Poor germination of seeds for this plant is a serious problem tomass production. The first step to improve this precious plant is to produce sterile plantlets in order to prepare explants of appropriate vigor. In this study, in vitro culture of Salvia leriifolia embryo was performed through a...

Pistachio is one of the most important nuts and its mass production using tissue culture techniques is of great importance. Micro-propagation has many complications. Contamination is one of the critical limitations in the establishment stage. This study focused on different NaClO and HgCl2 concentrations and exposure times. Shoot tip necrosis (STN) is one of the most common problems during larg...

A protocol has been developed for the direct induction of adventitious shoots from leaf explants of in vitro raised Anthemis xylopoda O.Schwarz, a critically endangered Turkish endemic. The Murashige and Skoog (MS) media supplemented with N–benzyladenine (BA), kinetin (KIN), and thidiazuron (TDZ) were used in regeneration experiments. BA at 0.5 mg L concentration was chosen as the optimal treat...

−Biodegradation of methylene chloride by a mixed microbial culture, isolated from a common sewage treatment plant, was investigated in a batch system. Batch experiments were performed at room temperature (27 C) and pH value of 7. The methylene chloride concentration in growth media varied from 25 mgl to 250 mgl. A maximum observed degradation was 1 mglh at 100 mgl of methylene chloride. The cul...

Mg is an important determinant of erythrocyte cation transport system(s) activity. We investigated cation transport in erythrocytes from mice bred for high (MGH) and low (MGL) Mg levels in erythrocytes and plasma. We found that K-Cl cotransport activity was higher in MGL than in MGH erythrocytes, and this could explain their higher mean corpuscular hemoglobin concentration, median density, and ...

leaf and root explants from 10 to 20 day– old seedlings of plantago lanceolata, were cultured on ms, msh, nt and b5 basal media with various concentrations of different plant growth regulators. the best callus induction was obtained with 0.4 mgl-1 2,4-d in msh i with 400 callus index. callus growth was significantly stimulated (p=0.05)with 0.8 mgl-1 2,4-d and 0.1 mgl-1 kin in msh ii, with 7...
