We investigated the treatment effect of non-invasive infiltration on early caries caused by different degrees of enamel demineralization. Forty specimens of early enamel caries were prepared and divided into low and high demineralization groups. After treatment with non-invasive infiltration, the specimens were placed under cariogenic conditions. Color measurements were determined using a spect...

This report describes a case of rectal cancer with endoscopically observable white nodules caused by distal intramural lymphatic spread. A 57-year-old female presented to our hospital with frequent diarrhea and hemorrhoids. Computed tomography showed bilateral ovarian masses and three hepatic tumors diagnosed as rectal cancer metastases, and also showed multiple lymph node involvement. The pati...

We describe a microarray design based on the concept of error-correcting codes from digital communication theory. Currently, microarrays are unable to efficiently deal with "drop-outs," when one or more spots on the array are corrupted. The resulting information loss may lead to decoding errors in which no quantitation of expression can be extracted for the corresponding genes. This issue is ex...

The vision of the Internet of Things (IoT) has sparked considerable efforts in research and development over the past decade. Much of these efforts were driven by applications of RFID technology for monitoring the flow of goods and prominent early adopters such as Wal-Mart and Metro Group. Also, the global standards organization GS1 provided a number of well recognized specifications that are t...

AIM Scattered white spots (SWSs) in the descending duodenum are an uncommon finding of upper gastrointestinal system endoscopy (UGSE). Intestinal lymphangiectasia, chronic nonspecific duodenitis and giardiasis are associated with a SWS appearance. The aim of this study was to determine the frequency of SWS during routine endoscopy, as well as to evaluate the effect of treatment on this finding....
