Development of portable infectious disease detector

...le such smallnumbers of cells, they have adapted a method for molding micro-channelsand valves into a material similar to that used in soft contact lenses.This has given them the capability to capture, manipulate, grow andstudy single living cells in extraordinarily small containers--volumesthat are barely ...

An entropy-based gene selection method for cancer classification using microarray data

...pecific regulatory pathways. Here an entropy-based method is proposed that selects genes related to the different cancer classes while at the same time reducing the redundancy among the genes. Results The present study identifies a subset of features by maximizing the relevance and minimizing the redundan...

Study of genomic DNA leads to new advances in cancer diagnostics

...niversity of Illinois at Chicago have identified a method of assessing the malignant potential of cells based on the sensitivity of cellular DNA to enzyme digestion. The article by Andrew J. Maniotis et al., "Chromatin sensitivity to Alu I restriction enzyme decreases with malignancy and is regulated by the...

NJIT Presidential Award winner takes stem cell research another step

...h surgeries, patients lose their limbs. But if her method of implanting stem cells is shown to induce bone repair, amputation may not be necessary. Stem cells could also help patients suffering from osteoporosis, whose fractured bones can be regenerated by the cells. Arinzeh has pushed the basic science of...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...trast via genetic instructions." "The new imaging method is a platform technology that can be adapted for many tissue types and for a range of preclinical uses in conjunction with emerging molecular therapeutic strategies," Ahrens said. Ahrens' new approach uses magnetic resonance imaging (MRI) to monitor...
