The information gained from the changes in CPC counts during exercise may be more useful to cardiologists in risk stratifying these patients than the treadmill exercise test itself, the researchers say.
A newly engineered peptide called IBP-CP24 has the potential to be further developed as a long-acting anti-HIV drug that can be used alone or in combination with a broad neutralizing antibody for the treatment and prevention of HIV-1 infection, according to a new study.
Women who initiate medical abortion but opt to stop in the middle of treatment may be at risk for serious blood loss, a study finds. Researchers found this is true even for women who use an experimental treatment that claims to 'reverse' the effects of the abortion pill. The study provides important insights into the safety of using high doses of progesterone during early pregnancy to try to stop a medical abortion.
Researchers have developed a more accurate method of measuring bispehnol A (BPA) levels in humans and found that exposure to the endocrine-disrupting chemical is far higher than previously assumed. The study provides the first evidence that the measurements relied upon by regulatory agencies, including the US Food and Drug Administration, are flawed, underestimating exposure levels by as much as 44 times.
A person's risk of developing cancer is affected by genetic variations in regions of DNA that don't code for proteins, previously dismissed as 'junk DNA', according to new research. This new study shows that inherited cancer risk is not only affected by mutations in key cancer genes - known as oncogenes and tumor suppressor genes - but that variations in the DNA that controls the expression of these genes can also drive the disease.
Researchers lift the veil on the 'conductor' plant root stem cell gene that helps orchestrate and coordinate stem cell division of different root stem cell types, ensuring the harmonic communication necessary for plant growth and maintenance.
For the first time, researchers have used a chip-based sensor with an integrated laser to detect very low levels of a cancer protein biomarker in a urine sample. The new technology is more sensitive than other designs and could lead to non-invasive and inexpensive ways to detect molecules that indicate the presence or progression of a disease.
The clustering of protected habitats in the Americas near international borders makes many iconic, wide-ranging animals physically dependent on good relations between neighboring countries and wildlife-friendly borders.
Little bits of black carbon littering the ocean floor, separate and distinct from the organic carbon believed to come from the ocean's surface. The source of that strange, and older, carbon has now been identified. The discovery is an important step in understanding the marine carbon cycle.
Silversword plants of Hawai'i - known by their Hawai'ian name 'ahinahina which translates to very grey - are unique to the Maui's Haleakala volcano summit area and to the Mauna Kea and Mauna Loa volcanoes on the Big Island. Each volcanic mountain has its own unique type of silversword.
Researchers have created the first comprehensive database of all the wildfire fuels that have been measured across North America. Ultimately, it can help scientists make formed decisions about fire and smoke situations.
Unlike wine, which generally improves with time, beer does not age well. Usually within a year of bottling, the beverage starts to develop an unpleasant papery or cardboard-like flavor that drinkers describe as 'stale.' Now, researchers have engineered lager yeast to make more molecules that protect beer against staling, resulting in improved flavor stability.
Using a clever technique that causes unruly crystals of iron selenide to snap into alignment, physicists have drawn a road map that reveals the quantum ''rules of the road'' that electrons must follow in the enigmatic superconductor.
Our Milky Way Galaxy consists of two disk-like structures, known as ‘thick’ and ‘thin’ disks. The thick disk contains only about 20% of the Galaxy’s total stars, and, based on its vertical puffiness and composition, is thought to be the older of the pair. Using data from NASA’s Kepler space telescope, astronomers have calculated that [...]
