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

...fewer factors. Finally, patients with the sharpest rises in protein levels had lower chances for survival, with patients who had a history of smoking experiencing the largest spikes. (For this reason, estimates of relative risk of death were adjusted to exclude the compounding effects of smoking.) Becau...

Bats get the munchies too!

...eeting in Glasgow. The concentration of ethanol rises in fleshy fruits, such as figs and dates, as they ripen. Egyptian fruit bats prefer these fruits when they are ripe, however high concentrations of ethanol (around 1%) are toxic to the animals. Intoxicated bats may also be less able to respond to att...

Male-killing bacteria makes female butterflies more promiscuous

'Guardian of the genome' protein found to underlie skin tanning

...hey also knew that the amount of POMC within cells rises sharply when they're exposed to UV rays. But they didn't know what caused the POMC to increase. One possibility was p53. When Fisher and his colleagues examined the section of the gene for POMC that promotes production of the protein, they found i...

Reminding doctors which antibiotics to prescribe cuts C. difficile infection rates

... amoxicillin/clavulanate. To prevent future CDI rises as a result of the increased use of amoxicillin/clavulanate, a new narrow-spectrum policy was implemented as part of the hospital's clinical governance programme at the beginning of July 2001. This policy recommended less use of amoxicillin/clavulana...

Osteoarthritis may be sign of faster 'biological ageing'

...ne of the sites most often affected. Its frequency rises dramatically with age, but it is still not known exactly what causes it. Unsurprisingly, the findings showed that white cell telomere lengths were associated with chronological age. The older a person was, the shorter they were. But among the 160...

How mammals fuel milk production may have implications for cancer

...the researchers found that the protein kinase Akt1 rises in concentration during pregnancy and lactation, suggesting a potential developmental role for the kinase in milk production. Another study showed that permanent activation of Akt1 in the mammary glands of mice leads to early lipid accumulation durin...

Reef warns of sea level rise

...of the Last Interglacial warm period" "Sea level rises and falls have occurred throughout geological history and are all slightly different from one another. However what took place in the last period of global warming 125,000 years ago gives us an idea of what to expect under the current phase," he sai...

Jefferson scientists identify gene mutation potentially involved in breast cancer initiation

...ceptors, yet the receptor activity for some reason rises dramatically in premalignant lesions and cancer. Dr. Lisanti's team developed mice lacking the Caveolin-1 gene and found a dramatic increase in both number and activity of estrogen-positive receptors in mouse breast tissue, specifically in breast ep...

Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere

Researchers discover which organs in Antarctic fish produce antifreeze

... Celsius. These species dwell in water that rarely rises above the freezing point and is regularly filled with ice crystals. From the intestine, the AFGPs are, apparently, absorbed into the blood. This hypothesis is based on the near-identical composition and abundance of AFGPs found in the fish serum. ...

Study finds how organs monitor themselves during early development

... In three days the number of primordial germ cells rises from twelve cells to 100 cells. The scientists started by looking at larvae with defects that cause them to have too few germ cells. The animal could well mature with this defect and suffer from reduced fertility. But it does not. Instead, they f...

Thin tough skin, slow-growing gills protect larval Antarctic fish

...elsius. The water where these species dwell rarely rises above the freezing point and is regularly filled with ice crystals. "The way that we've understood how adult polar fishes survive has been based on their use of these antifreeze proteins to lower the freezing point of their internal fluids," said le...

Predicting success

...When the internal pressure created by these fluids rises above a certain level, it acts as a barrier that keeps drugs and other materials from entering the tumor. The method the Institute scientists developed can measure, with a non-invasive MRI scan, whether the fluid pressure in cancer tissues is at le...

Sea Ice May Be on Increase in the Antarctic

...ls have a highly coordinated mechanism that senses rises in blood glucose and converts that information into signals that increase the secretion of insulin, Imai explained. Insulin produced by the pancreas allows cells to take up glucose from the bloodstream and burn it for energy. A failure to make or res...

Pregnant women at higher risk for HIV, Uganda study finds

The risk of acquiring HIV rises during pregnancy, according to a study of women in Uganda's Rakai District led by researchers at the Johns Hopkins Bloomberg School of Public Health. The increased risk for acquiring HIV remained even after researchers controlled for behavior and oth...

Anammox bacteria produce nitrogen gas in oceans' snackbar

A unique combination of microbiological methods involving high resolution nutrient profiles, experiments with stable isotope labeled nutrients, depth profiles of unique membrane lipids (ladder molecules), fluor...

Harmful chemicals may reprogram gene response to estrogen

...to vaginal cancer, the incidence of uterine tumors rises to almost 100 percent. By comparison, slightly more than half of the unexposed animals, those having only the genetic defect, developed the uterine tumors. DES is a drug that was prescribed for women from 1938 to 1971 to prevent miscarriages and pre...
