Blood test may help signal tumor's remission, return in throat cancer patients

A blood test that detects proteins commonly released by a growing tumor could one day become a useful tool for monitoring the effectiveness of chemotherapy and radiation treatment in people with advanced throat cancer, according to a study published in the June 1, 2007, issue...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...ved structure on one end (the outer segment) which detects light and sends signals to the brain, a function requiring a large amount of energy. "LCA is usually a disease where protein function has been lost completely, but carriers of just one copy of the mutation, who will almost certainly have reduced p...

Detecting cold, feeling pain: Study reveals why menthol feels fresh

...eveals one of the key mechanisms by which the body detects temperature sensation. But in so doing it also illuminates a mechanism that mediates how the body experiences intense stimuli – temperature, in this case – that can cause pain. As such, the receptor – known as menthol receptor TRPM8 -- provides a...

Anthrax paralyzes immune cells with lethal toxin, UF research shows

... They hope to develop a diagnostic blood test that detects the bacterium by checking for telltale changes in protein expression. Southwick's team used an unusual approach to tease out the anthrax toxin's effects on cell migration: They allowed the immune cells to be hijacked by another bacterium, Listeria...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

...e developed a new electro-chemical biosensor which detects the presence, in food, of very small amounts of atrazine –one of the most widely used herbicides in agriculture and which also has very long lasting effects on the environment- as well as antibiotics in food. The biosensor is faster, more portable an...

In obesity, brain becomes 'unaware' of fat

...mice show that a sensor in the brain that normally detects a critical fat hormone—causing a cascade of events that keeps energy balance in check—fails to engage. Meanwhile, the rest of the metabolic pathway remains ready to respond. “Obesity is not a failure of will power, it is a biological failure,?said M...

Columbia scientists determine 3-dimensional structure of cell's 'fuel gauge'

...m, where it does damage, and into cells. When AMPK detects low levels of ATP in the cell, it works through a different mechanism to increase how much glucose the cell takes in and uses to create ATP. Research in rodent models has shown that AMPK activators can lessen the pathologies associated with diabetes...

New test for most virulent HPV strains under study

...nce of 14 types of cancer-causing HPV. A test that detects 13 types of HPV already is commercially available, so the new test could become the second non-type-specific HPV test on the market. Dr. Ferris, who was involved in early studies of the HPV vaccines, hopes the new tests will one day provide better...

Light-based probe 'sees' early cancers in first tests on human tissue

...u would find in the stomach." The fa/LCI device detects irregularities in the nucleus, or central component, of cells, through changes in the way laser light scatters. "The size and shape of cell nuclei are powerful indicators of this precancerous condition called dysplasia, which literally means 'bad gro...

Colour sensor breath test can detect lung cancer

...The test comprises a chemical colour sensor, which detects tiny changes in the unique chemical signature of the breath of people with lung cancer. Metabolic changes in lung cancer cells cause changes in the production and processing of volatile organic compounds, which are then breathed out The researc...

Train your brain to hear your friends at a party

...relies on the fact that we have two ears, and each detects an individual sound at a slightly different time (a sound coming from the left will reach the left ear slightly faster than it reaches the right ear). This is known as binaural or "spatial" hearing because it helps us identify where a sound is coming...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...st known as polymerase chain reaction (PCR), which detects the virus itself by copying it many times. The test can take anywhere from several days to two weeks. Tripp said the latter is clearly too long, especially in light of emerging threats such as H5N1 avian influenza. "For some respiratory viruses, y...

Detecting microalgae in coastal waters

We hope this instrument will characterize microalgal populations rapidly and easily, for instance for pre-screening samples for the potentially...

New technology used to construct the first map of structural variation in the human genome

...b-microscopic resolution, and because the analysis detects SNPs--single-nucleotide polymorphisms--in addition to CNVs, it will find widespread use among researchers performing disease-association studies." ...

Robots manipulating animal behaviour

...ognition and attraction. For example, when a roach detects another roach, it may approach it, move away or stop. Cockroaches were chosen here because their pheromones are better understood than those found on other gregarious insects, such as ants. According to coordinator Jean-Louis Deneubourg, from the Un...

Diabetes research takes wing thanks to long-lived fruit fly

...d we eat into forms that the body can utilize. JNK detects stress in the environment and not only prepares the body to deal with insults from the environment, but also limits the amount of insulin, preparing the body for stress by slowing its metabolism and limiting its energy output. It might also offer a n...

Higher risk for cervical cancer seen among women infected with multiple HPV types

...r "pap smear" ?should be replaced with a test that detects the presence of a HPV co-infection and identifies each HPV genotype. If an infection is present, the current test cannot determine whether it was triggered by just one genotype or multiple types of HPV. Because the HPV test used by Franco and his ...

One-third of adults with diabetes still don't know they have it

...ES is unique because it includes a blood test that detects undiagnosed diabetes and IFG. "This study updates and generally corroborates earlier analyses that were based on 2 years of NHANES data," said lead author Catherine Cowie, Ph.D., of the National Institute of Diabetes and Digestive and Kidney Disease...

New crop of technology reveals plant health

...oups of plants are getting too hot. Another sensor detects chlorophyll fluorescence, which tells the system the rate at which the plant is absorbing energy. That reflects the current state of photosynthesis, itself a reflection of the plant's health. These sensors communicate their data through specially d...
