A multinational South American team from Peru, Brasil and Bolivia led by the Universidad de San Martin de Porres at Lima, Peru, published the first genetic study on the modern descendants of the imperial Inka lineages in the journal Molecular Genetics and Genomics.
Novel technology developed at UT Health San Antonio gives rise to mouse pancreatic tumors that have the same traits as human pancreatic cancer. A U.S. patent is pending on the invention.
The technology could revolutionize studies of pancreatic cancer initiation and progression and spur new drug development. An article published in the journal Carcinogenesis (Oxford University Press) describes this unique approach. Results of the research were made available online in November 2017 ahead of peer-review and print publication in February 2018.
WASHINGTON - Human airways already demonstrate gender-based differences in DNA methylation signatures at birth, providing an early hint of which infants may be predisposed to develop respiratory disorders like asthma later in life, a research team reports in a paper published online April 3, 2018, in Scientific Reports.
In a review article published April 5 in the New England Journal of Medicine, scientist Andrew Feinberg, M.D., calls for more integration between two fields of DNA-based research: genetics and epigenetics.
Gains in the ability to sustain attention developed through intensive meditation training are maintained up to seven years later, according to a new study published in the Journal of Cognitive Enhancement. The study is based on the Shamatha Project, a major investigation of the cognitive, psychological and biological effects of meditation led by researchers at the University of California, Davis, Center for Mind and Brain.
James Cook University researchers in Australia have helped develop a new way to save endangered African wild dogs.
Dr Damien Paris and PhD student Dr Femke Van den Berghe from the Gamete and Embryology (GAME) Lab at James Cook University, have successfully developed a sperm freezing technique for the species (Lycaon pictus).
The highly efficient pack hunters have disappeared from most of their original range across sub-Saharan Africa due to habitat destruction, human persecution and canine disease, leaving less than 6,600 animals remaining in the wild.
Naturally occurring pigments in berries, also known as anthocyanins, increase the function of the sirtuin 6 enzyme in cancer cells, a new study from the University of Eastern Finland shows. The regulation of this enzyme could open up new avenues for cancer treatment. The findings were published in Scientific Reports.
Bonobos are willing to share meat with animals outside their own family groups. This behaviour was observed in the Democratic Republic of the Congo and is documented in a new study in Springer's journal Human Nature. Even though bonobo apes have been studied for years, animal behaviourists have only realised in the past 25 years that these primates do not only eat plants, but similar to the common chimpanzee, also hunt and share their catch among members of their own social group.
In a new BJU International study, women with urinary incontinence reported declines in sexual activity and arousal over the last year, and they expressed increased concern about their frequency of sexual activity and ability to become sexually aroused. Men with urinary incontinence reported declines in sexual desire, increased erectile and orgasm difficulties, and concern about these sexual functions.
WILMINGTON, Del. (April 5, 2018) - Children whose families have elevated psychological and social risks, including child behavior problems, parent mental health issues, and family financial difficulties, were more likely to drop out of weight management treatment and less likely to have an improvement in weight status, according to a study published online today by the Journal of Pediatrics.
Dynamic interactions between the nervous system, hormones and the immune system are normally on-going but in diabetes the balance is disturbed. The two studies published in EBioMedicine by an international research team from Uppsala University highlight the importance of the neurotransmitter gamma-aminobutyric acid in both Type 1 and Type 2 diabetes.
Palaeontologists have discovered part of the skeleton of a 180 million-year-old pregnant ichthyosaur with the remains of between six and eight tiny embryos between its ribs.
Researchers from RMIT University have developed a new artificial enzyme that uses light to kill bacteria.
The artificial enzymes could one day be used in the fight against infections, and to keep high-risk public spaces like hospitals free of bacteria like E. coli and Golden Staph.
E. coli can cause dysentery and gastroenteritis, while Golden Staph is the major cause of hospital-acquired secondary infections and chronic wound infections.
An international research consortium used neuroimaging techniques to analyze the brains of more than 3,800 volunteers in different countries. The largest study of its kind ever conducted set out to investigate anatomical similarities and differences in the brains of individuals with different types of epilepsy and to seek markers that could help with prognosis and treatment.
Virginia Tech College of Natural Resources and Environment research published in the scientific journal PLOS ONE shows that private landowners trust conservation agencies more and have better views of program outcomes when they accompany conservation biologists who are monitoring habitat management on their land.
