developed LAMP method targeting LasA I gene con- tained 12 nearly identical tandem repeat for more rapid and sensitive detection of CLas than other methods. Positive re- sults were recorded only for LAMP reactions where HLB- infected samples were used as template both by visual ob- servation of color change within the reaction tubes and by the presence of DNA bands on agarose gels, and sequence... these bacteria within infected plants can make reliable detection difficult. It was known loop-mediated isothermal amplification (LAMP) method has the advantages of being highly specific, rapid, efficient, and laborsaving for detection of plant pathogens. We developed a new LAMP method targeting gene contained tandem repeat for more rapid and sensitive detection of Candidatus Liberibacter asiaticus (CLas), putative causal agent of the citrus huanglongbing. This new LAMP method was 10 folds more... -

of miR-122 was observed in the 72 h group, and this time-course change in miRNA expression, along with histopathological findings in the liver, are useful for the detection of DILI. However, the expression levels of other miRNAs (miR-155 and -21) that reflect inflammation and regeneration of hepatocytes did not differ significantly between the treatment and vehicle groups. miR-122 is a... multiple circulating microRNAs (miRNAs) have been reported to be potential biomarkers for DILI. To adapt and validate miRNAs for clinical use, we investigated the time-course changes in miR-122 expression levels in an acetaminophen-induced liver injury model in rats. In addition, miR-155 and miR-21 were evaluated as makers of inflammation and regeneration, respectively, to characterize liver status. Our results revealed that miR-122 is an early and sensitive biomarker of hepatocellular injury at... -

a novel method for direct detection of BH4 and dopamine in rat brain using LC-ESI-MS [20]. Here, the method was applied to the MPTP-induced mouse models of PD to monitor the changes of dopamine concen- tration and the levels of endogenous BH4. We directly quantified the endogenous levels of dopamine in ICR, C57BL/6, and Balb-C mouse strains using LC-MS/MS. The changes of neurotransmitter... of newly developed new drugs before human application. However, which of the plethora of experimental animal species to use in model development can be perplexing. Administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a very well known method to induce the symptoms of Parkinson's disease in mice. But, there is very limited information about the different sensitivities to MPTP among mouse strains. Here, we tested three different mouse strains (C57BL/6, Balb-C, and ICR) as a... -

Not detection of A. citrulli in our studied soil samples might be due to the above mentioned reasons. Bacterial diversity across the different geographical locations. Bacterial diversity was analyzed in... Knowledge and better understanding of functions of the microbial community are pivotal for crop management. This study was conducted to study bacterial structures including Acidovorax species community structures and diversity from the watermelon cultivated soils in differ- ent regions of South Korea. In this study, soil samples were collected from watermelon cultivation areas from various places of South Korea and microbiome analysis was performed to analyze bacterial communities in- cluding... -

Aggregation of infected plants influenced variability of DI estimations, and it was pointed out that more extensive investigation should be conducted on broad range of DI in order to establish sampling method giving uniform sampling precision. Fusarium graminearum was shown to be predominant Fusarium species in Serbia (72.6%) using sequence-characterized amplified region analysis. Interestingly F. oxysporum was isolated in higher frequencies (27.4%)... -

In this study, we aimed to culture the functionally active fraction of an upland soil microbiome, which can suppress tomato bacterial wilt. The microbiome fraction (MF) from the rhizosphere of Hawaii 7996 treated with an upland soil or forest soil MF was successively cultured in a designed modified M9 (MM9) medium partially mimicking the nutrient composition of tomato...
