A search for biomarkers for early detection of colorectal cancer

Using two-dimensional gel electrophoresis, 27 differentially expressed proteins were identified in colorectal adenoma, compared with individual-matched normal mucosa and cancer tissue. In those proteins, the differential expression of two novel proteins, mimecan and thioredoxin domain-containing protein 5 (TXNDC5), were validated by Western-blot. This study clearly demonstrated that absence of mimecan and up-regulation of TXNDC5 were involved in the early development of colorectal cancer.

Ultrasensitive Optical Sensor Detects Viruses Fast

sciencebaby submitted, created time 1 year 10 months (www.medicalnewstoday.com)

Scientists in The Netherlands have developed an ultrasensitive sensor that can be used in a handheld device to, within minutes, detect various viruses and measure their concentration. The sensor could be used to quickly screen people at hospitals, airports and emergency clinics to control outbreaks of diseases such as SARS and the bird flu. Amazing. isn't it?
