Understanding active pharmaceutical ingredients

Understanding active pharmaceutical ingredients

Active pharmaceutical ingredient (API), is the term used to refer to the biologically active component of a drug product (e.g. tablet, capsule). Drug products are usually composed of several components Continue reading

Sperm-inspired robots controlled by magnetic fields may be useful for drug delivery, IVF, cell sorting and other applications

Sperm-inspired robots controlled by magnetic fields may be useful for drug delivery, IVF, cell sorting and other applications

A team of researchers at the University of Twente (Netherlands) and German University in Cairo (Egypt) has developed sperm-inspired microrobots, which can be controlled by oscillating weak magnetic fields. Described in a cover article in the journal Applied Physics Letters , which is from AIP Publishing, the 322 micron-long robots consist solely of a head coated in a thick cobalt-nickel layer and an uncoated tail.

Subtle change in DNA, protein levels determines blond or brunette tresses, study finds

Subtle change in DNA, protein levels determines blond or brunette tresses, study finds

A molecule critical to stem cell function plays a major role in determining human hair color, according to a study from the Stanford University School of Medicine. The study describes for the first time the molecular basis for one of our most noticeable traits. Continue reading

Researchers see stem cells take key step toward development: A first

The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells, with potential to become any tissue type, to take the first step to specialization. It is the first time this critical step has been demonstrated in a laboratory. University of Illinois researchers, in collaboration with scientists at Notre Dame University and the Huazhong University of Science and Technology in China, published their results in the journal Nature Communications Continue reading

Green tea could reduce pancreatic cancer risk: Study explains how

Green tea and its extracts have been widely touted as potential treatments for cancer, as well as several other diseases. But scientists have struggled to explain how the green tea and its extracts may work to reduce the risk of cancer or to slow the growth of cancer cells. Continue reading

Radiation for prostate cancer linked to secondary cancers, study finds

Radiation for prostate cancer linked to secondary cancers, study finds

Among men treated for prostate cancer, those who received radiation therapy were more likely to develop bladder or rectal cancer, according to a new study from the University of Michigan Comprehensive Cancer Center. “Overall the incidence of these cancers is low Continue reading

Stress degrades sperm quality, study shows

Psychological stress is harmful to sperm and semen quality, affecting its concentration, appearance, and ability to fertilize an egg, according to a study led by researchers Columbia University’s Mailman School of Public Health and Rutgers School of Public Health. Results are published online in the journal Fertility and Sterility Continue reading

In Africa, STI testing could boost HIV prevention

In Africa, STI testing could boost HIV prevention

To maximize HIV prevention efforts in South Africa and perhaps the broader region, public health officials should consider testing for other sexually transmitted infections when they test for HIV, according to a new paper in the journal Sexually Transmitted Infections . STIs can make HIV easier to transmit even after antiretroviral therapy has begun, so rooting out STI co-infections in patients should improve HIV prevention. Continue reading

‘Nanodaisies’ deliver drug cocktail to cancer cells

Biomedical engineering researchers have developed daisy-shaped, nanoscale structures that are made predominantly of anti-cancer drugs and are capable of introducing a “cocktail” of multiple drugs into cancer cells. Continue reading
