A plant＇s ability to maintain or improve its yield under limiting conditions,such as nutrient de ficiency or drought,can be strongly in fluenced by root system architecture（RSA）,the three-dimensional distribution of the different root types in the soil. The ability to image,track and quantify these root system attributes in a dynamic fashion is a useful tool in assessing desirable genetic and physiological root traits. Recent advances in imaging technology and phenotyping software have resulted in substantive progress in describing and quantifying RSA. We have designed a hydroponic growth system which retains the three-dimensional RSA of the plant root system,while allowing for aeration,solution replenishment and the imposition of nutrient treatments,as well as high-quality imaging of the root system. The simplicity and flexibility of the system allows for modi fications tailored to the RSA of different crop species and improved throughput. This paper details the recent improvements and innovations in our root growth and imaging system which allows for greater image sensitivity（detection of fine roots and other root details）,higher ef ficiency,and a broad array of growing conditions for plants that more closely mimic those found under field conditions.

AIM To report our one-year experience with computer assisted propofol sedation(CAPS) for colonoscopy as the first United States Medical Center to adopt CAPS technology for routine clinical *** Between September 2014 and August 2015, 2677 patients underwent elective outpatient colonoscopy with CAPS at our center. All colonoscopies were performed by 1 of 17 gastroenterologists certified in the use of the CAPS system, with the assistance of a specially trained nurse. Procedural success rates, polyp detection rates, procedure times and recovery times were recorded and compared against corresponding historical measuresfrom 2286 colonoscopies done with midazolam and fentanyl from September 2013 to August 2014. Adverse events in the CAPS group were *** The mean age of the CAPS cohort was 59.9 years(48.7% male); 31.3% were ASA?Ⅰ, 67.3% ASA Ⅱ and 1.4% ASA Ⅲ. 45.1% of the colonoscopies were for screening, 31.5% for surveillance, and 23.4% for symptoms. The mean propofol dose administered was 250.7 mg(range 16-1470 mg), with a mean fentanyl dose of 34.1 mcg(0-100 mcg). The colonoscopy completion and polyp detection rates were similar to that of historical measures. Recovery times were markedly shorter(31 min vs 45.6 min, P < 0.001). In CAPS patients, there were 20(0.7%) cases of mild desaturation(< 90%) treated with a chin lift and reduction or temporary discontinuation of the propofol infusion, 21(0.8%) cases of asymptomatic hypotension(< 90 systolic blood pressure) treated with a reduction in the propofol rate, 4(0.1%) cases of marked agitation or discomfort due to undersedation, and 2 cases of pronounced transient desaturation requiring brief(< 1 min) mask ventilation. There were no sedation-related serious adverse events such as emergent intubation, unanticipated hospitalization or permanent injury. CONCLUSION CAPS appears to be a safe, effective and efficient means of providing moderate sedation for colonoscopy in relatively healthy patients. Recovery

AIM: To investigate the potential burden of nonalcoholic steatohepatitis(NASH) and advanced fibrosis in a hispanic ***: Four hundred and forty two participants with available ultrasonography data from the Cameron County Hispanic Cohort were included in this study. Each participant completed a comprehensive questionnaire regarding basic demographic information, medical history, medication use, and social and family history including alcohol use. Values of the nonalcoholic fatty liver disease fibrosis score(NFS), FIB4 index, BARD score, and Aspartate aminotransferase to Platelet Ratio Index(APRI) were computed using the blood samples collected within 6 mo of liver ultrasonography from each participant. Hepatic steatosis was determined by ultrasonography. As part of univariable analysis, for continuous variables, comparisons among groups were performed with student-t test, one way analysis of variance, and Mann-Whitney test. Pearson χ2 and the Fisher exact test are used to assess differences in categorical variables. For multivariable analyses, logistic regression analyses were performed to identify characteristics associated with hepatic steatosis. All reported P values are based two-sided tests, and a P value of less than 0.05 was considered to indicate statistical ***: The mean age and body mass index(BMI) of the study participants were 49.1 years and 31.3 kg/m2, respectively. Among them, 65.6% were females, 52% had hepatic steatosis, 49.5% had metabolic syndrome, and 29% had elevated aminotransferases. Based on established cut-offs for diagnostic panels, between 17%-63% of the entire cohort was predicted to have NASH with indeterminate or advanced fibrosis. Participants with hepatic steatosis had significantly higher BMI(32.9 ± 5.6 kg/m2 vs 29.6 ± 6.1 kg/m2, P < 0.001) and higher prevalence rates of elevation of ALT(42.2% vs 14.6%, P < 0.001), elevation of aspartate aminotransferase(38.7% vs 18.9%, P < 0.001), and metabolic syndrome(6
