It is noteworthy that colon cancer the fourth place in new cases and fifth mortalities according to global statistics 2018. Tumorigenesis displays specific correlation with metabolic alterations. A variety of metabolites, including ornithine (Orn), are related sources disease information retrieval human metabolome database. The regulation Orn pathway a key link survival cells. In this study, pl...

We have synthesized the characteristics of the seismogenic zone in the east Los Angeles basin by analyzing earthquake data recorded during the past 30 years (1981–2010). The seismicity is distributed along the Whittier fault, with the majority of earthquakes located adjacent to the south side, in the depth range from 0 to 9 km, with b value of 1:1 0:05 and mostly normal and strike-slip faulting...

Large-scale yield trials have traditionally been used to rate the reactions of released sugarcane varieties to ratoon stunting disease (RSD). These trials are time-consuming and require large tracts of land and are therefore not suitable for incorporation into a routine programme of disease screening of new genotypes. Using a tissue blot-enzyme immunoassay (TBIA) to determine the percentage of ...

In 2004, sugarcane thrips Fulmekiola serrata (Kobus) (Thysanoptera: Thripidae) was for the first time detected in southern African sugarcane. Since then it has become widespread in South Africa, and any control strategy would benefit from identifying and monitoring damage caused by this pest. Imaging spectroscopy is being investigated for this purpose, and is used in conjunction with space-born...

Naturally occurring bacterial endophytes were isolated from the stalks of six different sugarcane varieties. The highest numbers of bacterial populations were isolated from variety N12 and this variety was used for further investigations. Xylem sap as well as crushed cane sap was used for isolations, but no differences were observed between the type and numbers of species isolated. Endophytic b...

The naturally occurring polyamines putrescine, spermidine, and spermine are required for cell growth. Based on this requirement, several polyamine analogues that interfere with polyamine function and metabolism have been synthesized as antineoplastic agents. The symmetrically substituted N1,N12-bis(ethyl)spermine (BESpm), and unsymmetrically substituted N1-ethyl-N11-[(cyclopropyl)methyl]-4, 8-d...

Le métabolisme tumoral est étroitement lié à la tumorogenèse et varie selon le phénotype tumoral. Les techniques de métabolomique peuvent fournir des données quantitatives concernant un grand nombre métabolites permettent l’analyse nombreuses voies métaboliques intriquées. La tomographie par émission (TEP) positons au 18F-fluorodéoxyglucose (FDG) permet une mesure in vivo l’avidité cellulaire e...
