[ Sen. 10, subscore: 3.00 ]: The similar intron position between bean catalases and human catalase implies that the animal and plant catalases might have derived from a common progenitor gene sequence . [ Sen. 3, subscore: 2.00 ]: Phylogenies based on distances and parsimony analysis show that all plant catalases derive from a common ancestral catalase gene and can be divided into three distinct groups .

[ Sen. 8, subscore: 2.00 ]: The distinctive features of monocot-specific catalases are their extreme high codon bias at the third position and low degree of sequence similarity to other plant catalases .

[ Sen. 4, subscore: 1.00 ]: The first , and major , group includes maize Cat1 , barley Cat1 , rice CatB , and most of the dicot catalases . [ Sen. 5, subscore: 1.00 ]: The second group is an apparent dicot-specific catalase group encompassing the tobacco Cat2 and tomato Cat . [ Sen. 9, subscore: 1.00 ]: Similarities in the intron positions for several plant catalase genes support the conclusion of derivation from a common ancestral gene .

Score: 12.00 | Title: Catalytic pyrolysis of waste rice husk over mesoporous materials .
| Author: Jeon MJ Kim SS Jeon JK Park SH Kim JM Sohn JM Lee SH Park YK | Journal: Nanoscale Res Lett Citation: V : 7 P : 18 Year: 2012 Type: Publisher | Literature: oryza Field: abstract Doc ID: pub22221540 Accession (PMID): 22221540 | Matching Sentences: [ Sen. 8, subscore: 3.00 ]: The amount of aromatics increased remarkably as a result of catalytic upgrading , which is attributed to the strong Bronsted acid sites and the shape selectivity of the Meso-MFI catalyst The addition of Pt made the Meso-MFI catalyst even more active in deoxygenation and in the production of aromatics . [ Sen. 3, subscore: 2.00 ]: Using a catalytic upgrading method , the activities of the catalysts were evaluated in terms of product composition and deoxygenation . [ Sen. 5, subscore: 2.00 ]: Catalytic upgrading reduced the amount of oxygenates in the product vapor due to the cracking reaction of the catalysts . [ Sen. 7, subscore: 2.00 ]: While the amount of heavy phenols was reduced by catalytic upgrading , the amount of light phenols was increased because of the catalytic cracking of heavy phenols into light phenols and aromatics . [ Sen. 1, subscore: 1.00 ]: ABSTRACT : Catalytic fast pyrolysis of waste rice husk was carried out using pyrolysis-gas chromatography/mass spectrometry [ Py-GC/MS ] . [ Sen. 2, subscore: 1.00 ]: Meso-MFI zeolite [ Meso-MFI ] was used as the catalyst In addition , a 0 . 5-wt . % platinum [ Pt ] was ion-exchanged into Meso-MFI to examine the effect of Pt addition . [ Sen. 4, subscore: 1.00 ]: The structure and acid site characteristics of the catalysts were analyzed by Brunauer-Emmett-Teller surface area measurement and NH3 temperature-programmed desorption analysis .

[ Sen. 2, subscore: 2.00 ]: The present study seeks clues to the etiology of senile cataract , so that strategies to prevent or even delay cataract formation could be planned . [ Sen. 9, subscore: 2.00 ]: Though the study provided some clues to the etiology of senile cataract , further studies are needed to know the specific role of these factors in the causation of cataract , so that any preventive or control measures could be initiated in the community . [ Sen. 5, subscore: 1.00 ]: Logistic regression analysis technique was employed to study the associations between senile cataract and various variables . [ Sen. 6, subscore: 1.00 ]: RESULTS : Systolic blood pressure , duration of exposure to sunlight per day were associated with senile cataract in both the centres ( OR = 1 . 4 & 1 . 5 for systolic BP and 1 . 6 & 1 . 4 for exposure to sunlight ) . [ Sen. 7, subscore: 1.00 ]: Utilization of rice gruel ( OR = 0 . 5 ) , duration of exposure to fire & dust per day ( OR = 1 . 8 ) , family history of cataract ( OR = 5 . 0 ) , use of cheap cooking fuels ( OR = 1 . 8 ) , increased height ( OR = 0 . 7 ) and increased number of hours of work per day ( OR = 0 . 7 ) were other variables that showed significant association in either of the centres .

[ Sen. 10, subscore: 1.00 ]: Till such time , we have to fall back on the available surgical approach in control of senile cataract .
