Medical Xpress / Most IVF 'add-ons' show little evidence of boosting births, researchers find
There is a lack of evidence to suggest the majority of in vitro fertilization (IVF) add-ons improve fertility in patients undergoing IVF, according to a systematic review and meta-analysis published in The Lancet Obstetrics, ...
Phys.org / Drug peptides defy shape rules, activating receptors without full spiral form
When many of us think about how drugs work in the body, we may first think about how a drug gets into the body, such as a pill versus an injection. In the Gellman Group at the UW–Madison Department of Chemistry, researchers ...
Phys.org / Discovery of how cells maintain their DNA could shield key healthy cells from chemotherapy side effects
A new study conducted by scientists at the University of Sheffield in collaboration with researchers from UT Southwestern Medical Center in the U.S. has found a protein that could help guide which cells chemotherapies target. ...
Phys.org / Nanoparticles sneak antibodies into cells to inhibit cancer and inflammation
A delivery system that uses lipid nanoparticles to sneak proteins into cells can accomplish the same feat by smuggling therapeutic antibodies, new research has found.
Phys.org / Symbiotic partner-swapping or long-term fidelity? Partnership success between beetles and bacteria revealed
Some insects and microbes develop symbiotic partnerships that become so interdependent they can no longer survive without each other. But how specific are these heritable symbioses? Is it possible for the same species of ...
Phys.org / Unique instruments automate sample preparation, quality control for cryo-electron microscopy
Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 Nobel Prize in chemistry ...
Medical Xpress / Steep drop in metabolic coenzyme could trigger preterm labor
Declining placental concentrations of a molecule that plays a key role in metabolism appear to trigger the end of pregnancy and hasten labor and delivery, suggesting a study co-led by researchers at UT Southwestern Medical ...
Medical Xpress / For chronic knee pain, genicular artery embolization provides a new alternative
The procedure was "remarkably" successful. That's how Cynthia Schraf-Fletcher, 74, describes her experience with genicular artery embolization (GAE), a minimally invasive procedure that treats chronic knee pain. Nearly a ...
Medical Xpress / Keeping HIV at bay: New approach explores broadly neutralizing antibodies to treat infants
In the ongoing effort to find new therapeutics for infants born infected with the human immunodeficiency virus, an international team of investigators has discovered that babies can tolerate treatment with anti-HIV antibodies.
Phys.org / New energy-boosting quantum mechanism discovered in photosynthetic bacteria
Researchers have discovered how certain photosynthetic bacteria use a sophisticated quantum mechanism to increase their efficiency when capturing sunlight. The study, published today in the journal Nature Chemistry and led ...
Medical Xpress / Fat tissue could explain triple negative breast cancer spread—and point to treatments
Triple-negative breast cancer (TNBC) is aggressive and hard to treat. But the role of fat tissue in how the cancer spreads may help point toward new understanding and treatments, according to a new paper from scientists at ...
Phys.org / Einstein Probe detects mysterious X-ray transient that doesn't fit any known class
Astronomers have reported the discovery of an unusual X-ray transient detected by the Einstein Probe that does not fit any known class of cosmic explosions. The paper presenting its multiwavelength analysis was published ...
