BACKGROUND Hepatitis B virus(HBV)nucleos(t)ide analog(NA)therapy reduces liver disease but requires prolonged therapy to achieve hepatitis B surface antigen(HBsAg)*** is limited North American real-world data using non-invasive tools for fibrosis assessment and few have compared 1st generation NA or lamivudine(LAM)to tenofovir disoproxil fumarate(TDF).AIM To assess impact of NA on virological response and fibrosis regression using liver stiffness measurement(LSM)(i.e.,FibroScan®).METHODS Retrospective,observational cohort study from the Canadian HBV *** collected included demographics,NA,HBV DNA,alanine aminotransferase(ALT),and *** were HBV monoinfected patients,treatment naïve,and received 1 NA with minimum 1 year *** In 465(median 49 years,37%female,35%hepatitis B e antigen+at baseline,84%Asian,6%White,and 9%Black).Percentage of 64(n=299)received TDF and 166 were LAM-treated with similar median duration of 3.9 and 3.7 years,*** mean baseline LSM was 11.2 kPa(TDF)vs 8.3 kPa(LAM)(P=0.003).At 5-year follow-up,the mean LSM was 7.0 kPa in TDF vs 6.7 kPa in LAM(P=0.83).There was a significant difference in fibrosis regression between groups(i.e.,mean-4.2 kPa change in TDF and-1.6 kPa in LAM,P<0.05).The last available data on treatment showed that all had normal ALT,but more TDF patients were virologically suppressed(<10 IU/mL)(n=170/190,89%)vs LAM-treated(n=35/58,60%)(P<0.05).None cleared *** In this real-world North American study,approximately 5 years of NA achieves liver fibrosis regression rarely leads to HBsAg loss.

Emerging Jasmonate Transporters

Jasmonic acid （JA） and methyl jasmonate （MeJA） are highly mobile and, when applied to intact plants,, these compounds powerfully modulate gene expression. Moreover, activation of jasmonate-responsive genes usually occurs in tissues distal to the treatments. It therefore comes as no surprise that there are jasmonate transporters; these proteins are only now emerging and their discovery is important for a number of reasons. Firstlv.

Characterization of Spirooxazine and Spiropyran Hosted in Poly(Methyl Methacrylate) for Germicidal UV Source Indicator Application

Optics and Photonics Journal 2013年第7期3卷 11-16页

A characterization of photophysical properties of 1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3’-[3H]naphtha[2,1-b] [1,4]oxazine] (spirooxazine) and1’,3’-dihydro-1’,3’,3’-trimethyl-6-nitrospiro[2H-1-benzopyran-2,2’-(2H)-indole] (spiropyran) compounds hosted in poly(methyl methacrylate) (PMMA) was carried out. The parameters which influenced the photochromic behavior of both compounds were investigated. After ultraviolet (UV) irradiation, it was demonstrated that the temperature was the dominant factor which influenced the deactivation of both materials. For spiropyran, it was demonstrated that the process could be photo-induced with a certain wavelength which we have specified in this manuscript. It was also found that X-Ray did not affect the photo physical properties of spirooxazine and spiropyran. Finally, both materials could be used as low-cost germicidal UV indicators.

Location Based Services Acceptance and Adoption Evaluation: An Investigation on Mobile Phone Users’ Response to Awareness and Utilization of LBS Technology in Nairobi Kenya

引用

Journal of Computer and Communications 2021年第10期9卷 60-96页

作者： Charles Busera Wasomi edward Hunja Waithaka Moses Karoki Gachari David Ndegwa Kuria Department of Geomatics Engineering and Geospatial Information Systems Jomo Kenyatta University of Agriculture and Technology (JKUAT) Nairobi Kenya Department of Geomatics Engineering and Geospatial Information Systems Dedan Kimathi University of Technology (DKUT) Nyeri Kenya

Location Based Navigation System (LBNS) is a specific Location Based Service (LBS) purely for navigational purpose. These systems resolve position of a user by using GNSS/GPS positioning technologies, to which supplementary information on goods and services are tagged. The navigation services have become popular and can be installed on mobile phones to provide route information, location of points of interest and user’s current location. LBS has continued to face challenges which include “communication” process towards user reference. Location Based Service System conveys suitable information through a mobile device for effective decision making and reaction within a given time span. This research was geared at understanding the state of LBS technology acceptance and adoption by users in Nairobi Kenya. To do this a quantitative study was carried out through a questionnaire, to investigate mobile phone users’ response on awareness and use of LBS technology. Testing the growth of this technology in this region compared to predictions in previous studies using Technology Acceptance Model (tam), it is evident that many users may be aware of GPS functionality in mobile phones but are certainly yet to fully embrace the technology as they rarely use it. This points to some underlying challenges towards this technology within this part of the World, thereby recommending for deliberate monitoring and evaluation of LBS technology for sustenance growth based on user satisfaction and acceptance for improved usability.
