Studying the chemistry of drugs in wastewater

...echniques. Scientists found that the reactions are complicated and often produce several products, some unexpected. For instance, acetaminophen forms multiple products, two of which are highly toxic. All the drugs were transformed significantly, and their products were generally more "hydrophobic" than the paren...

Protein energy profiles offer clues about amyloids

Mitochondria findings may help beat wide range of disease

New findings explaining the complicated process by which the "energy substations" of human cells split apart and recombine may lay the groundwork for new treatment approaches to a wide range of diseases, including some cancers and neurodegenerative diseases such as Parkinson's and Alzheime...

For inferring the biological tree of life, simple is better

...f the evolutionary process. "It turns out that the complicated method performs well when reality is simple, but the simpler method is much more accurate when reality is complex," Thornton said. During the past decade, maximum likelihood has eclipsed maximum parsimony as a tool for evolutionary biologists, largel...

Insects implicated in the evolution of new human infectious diseases

... as well as other animals. "The picture is further complicated by climate change, which seems to be altering the range of places insects can survive and breed, bringing new insects which can carry devastating diseases such as malaria into the Northern hemisphere." In the case of Photorhabdus luminescens, the inf...

Immune system in a bottle could help prevent flu vaccine shortage

...ferentiation). Kotov's team didn't use robotics or complicated computer set-ups to make the scaffolds. Instead, they used heat and gel to make a simple mold. First, they infiltrated the crystal with sol gel. When the gel hardened in the channels between the spheres, scientists heated the crystal to burn away all...

Actin muscles in on DNA transcription

...ng protein. It recruits other proteins in the very complicated process our bodies use to transcribe DNA segments into messages made of RNA." These messages travel out to the cytoplasm, where they serve as templates for building proteins, including actin itself. "If actin is blocked, transcription can't begin," d...

Scientists find acid rain an unlikely ally in the battle against a greenhouse gas

...third of the global annual total methane. "It's a complicated process because multiple factors at microscopic to global scales interact in these processes," said Elaine Matthews, a scientist at NASA's Goddard Institute for Space Studies (GISS), New York. Matthews is co-author of the study on acid rain and metha...

Study links polycystic ovary syndrome with early vascular changes of heart disease

...basis by physicians unaware that a larger and more complicated ailment was present, PCOS today is increasingly being recognized as a lifelong hereditary reproductive endocrine condition with physical and emotional consequences. Common symptoms include infertility, irregular menstrual cycles, excess body hair, ov...

By impounding iron, FHC foils cell suicide, fuels inflammation

...hat come with current treatments. "In a long and complicated biochemical chain, this is one of the final links, which is exactly what we want," said study author Guido Franzoso, M.D., Ph.D., associate professor in the Ben May Institute for Cancer Research at the University of Chicago. "If we tamper with the f...

No getting around RET

...o the developing kidney, remains a thorny question complicated by the fact that GFR is much more widely expressed in the body than is RET and that, in vitro, cells expressing GFR1 without RET have been shown to respond to GDNF signals. A report by Hideki Enomoto (Team Leader, Laboratory for Neuronal Differentiat...

'Blind' cells see the light; maybe someday humans will, too

...ess of cochlear implants -- the eye is a much more complicated place, Kramer said. "This is a more organic, less invasive approach than electrodes," Kramer said, noting that insertion of electrodes can cause problems with biocompatibility. Electrodes also are large and tend to stimulate an entire bank of cells a...

Scientists generate human islet precursor cells in culture

...ts derived from donor pancreata into a person with complicated type 1 diabetes. The hope is that some of the transplanted cells will survive in the pancreas and continue producing insulin. A major obstacle to the wider use of islet transplantation as a treatment for type 1 diabetes is the small number of donor...

Researchers reconstruct parts of the genome of a common mammalian ancestor

...es leading to current mammals. This task is not so complicated where individual nucleotides changed in a particular lineage, because the original nucleotide often was retained in other lineages. It is much more difficult where stretches of DNA were inserted or deleted in the genomes of particular species. ...

Spider silks, the ecological materials of tomorrow?

...s into other cells or organisms. But this has been complicated by the nature of the genes, which include many repeated sequences and rely on a different codon reading system from ours. However, in recent studies parts of the genes were successfully inserted into the bacterium E. coli, mammal and insect cells, wh...

New system reduces risk of burns during interventional X-rays

"Patients undergoing such procedures sometimes develop erythema redness hair loss or even skin ne...

Strange ocean wave patterns raise questions about beach erosion

Scientists may have to take the new findings into account when they design computer models of beach erosion, nearshore circulation, or water quality. These topics are of partic...
