pHLIP, a novel technology to locate and treat tumors

...to be treated. Targeting is based on the fact that most tumors, even very small ones, are acidic as a result of the way they grow. “Since the mechanism is general, and since even very small tumors can be targeted, there is an exciting array of possible applications for pHLIP,?said Donald Engelman , E...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...tween 10-100 cells of it are typically enough ?but most are harmless to humans and can be used as a biological control mechanism to replace pesticide use. The researchers, from the universities of Bath, Bristol and Exeter, all in the UK, used the large caterpillar Manduca sexta (tobacco hornworm) to s...

Novel system developed to turn data into real-time, interactive 3-D images

... be applied to any large 3- or 4-D data set but is most readily applicable to medical images. For instance, CT scans generate large 3- and 4-D data sets. The new technology will produce a 3-D, high quality, real-time image of the data to help physicians and other medical professionals more clearly view, a...

Master regulatory gene of epithelial stem cells identified

...the skin, breast and prostate, which are among the most common human malignancies. The role of p63 in epithelial stem cells has been controversial. Some studies found that p63 maintains a steady pool of the regenerative cells, while other studies argued that p63 has more to do with causing the cells to d...

Cancer patients monitor fatigue in real time

Fatigue is one of the most common and distressing symptoms cancer patients experience during chemotherapy and radiation treatment, but it's difficult for health care professionals to accurately assess its severity. Nurse researchers at the University of Illinois at Chicago ar...

Alien plants attack using 'resource conservation' as weapon, researchers say

One of the most serious and least understood threats to the world's ecosystems is the problem of invasive species-exotic plants, animals and other organisms that are brought into habitats and subsequently spread at a rapid rate, often replacing native species and re...

Since these two species diverged most recently from human ancestors (about 5 and 14 million years ago respectively), this finding demonstrates that type II is a human-specific form that originated relatively recently, less than 5 million years ago. Gene sequencing revealed a mutation ...
