Long-term stability in some MCI patients could be predicted based on neuropsychological tests

Researchers from the Lisbon School of Medicine, University of Lisbon found that, in some mild cognitive impairment patients, real neuropsychological stability over a decade is possible and that long-term stability could be predicted based on neuropsychological tests measuring memory and non-verbal abstract reasoning.

Parasite egg DNA from ancient latrines shows people's diets from 500 B.C. to 1700 A.D.

Researchers from University of Copenhagen and Aarhus University have studied the DNA from the parasite eggs that are recovered from the faeces samples in ancient times.

Viruses can exploit a suprising weakness of brain cells to spark hydrocephalus

Viruses may spark hydrocephalus by exploiting a suprising weakness of cells that circulate fluid in the brain, says a new study by Duke University scientists.

Peak health plan premiums give rise to activism — and unconventional solutions

When Garnett and Dave Mellen sent their 19-year-old daughter, Gita, off to college an hour away at Virginia Commonwealth University last fall, they didn't expect to follow her.

Studies provide advanced knowledge about renal cancer

Cell, the most prestigious international journal in the field of biology, is today publishing a set of three papers on renal cancer. Among the authors of these papers is Dr José Ignacio López, head of the Pathological Anatomy Service of University Hospital Cruces and tenured lecturer in Pathological Anatomy at the UPV/EHU's Faculty of Medicine and Nursing.

Role of extrachromosomal pieces of DNA in cancer development and treatment resistance

Glioblastoma is the most common and aggressive form of brain cancer. Response to standard-of-care treatment is poor, with a two-year survival rate of only 15 percent.

Researchers discover genetic catalysts that accelerate evolution of antibiotic resistance in bacteria

Researchers at Oxford University have shown that it is possible to identify genetic catalysts that accelerate the evolution of antibiotic resistance in bacteria - and that this knowledge could be used to design treatments to stifle the development of resistance.

Scientists identify gene responsible for evolution of recombination rates

Genetics is a crapshoot. During sexual reproduction, genes from both the mother and the father mix and mingle to produce a genetic combination unique to each offspring. In most cases, the chromosomes line up properly and crossover. In some unlucky cases, however, "selfish DNA" enters the mix, causing abnormal crossovers with deletions or insertions in chromosomes, which can manifest as birth defects.

Study may explain how chemoresistance evolves over time in some triple-negative breast cancers

Triple-negative breast cancer is an aggressive form of the disease accounting for 12 to 18 percent of breast cancers. It is a scary diagnosis, and even though chemotherapy can be effective as standard-of-care, many patients become resistant to treatment.

Triple-negative breast cancer found to be chemoresistant prior to treatment

Difficult to treat and aggressive "triple-negative" breast cancer is chemoresistant even before chemotherapy begins, a new study by researchers from Karolinska Institutet and the University of Texas MD Anderson Cancer Center reports. The findings, which are published in the journal Cell, may lead to better and more personalized treatments for breast cancer.

Breathtaking evolution amongst Indonesian tribe - bigger spleens for free-diving

New evidence shows that the Bajau tribes from Indonesia, who are known to dive deep into the waters for up to 70 metres have evolved to develop larger spleens. Previous studies have shown that free dives and spleens have an association.

Case study shows how intravascular ultrasound imaging helps detect acute aortic syndrome

In the current issue of Cardiovascular Innovations and Applications (Volume 2, Number 4, 2018, pp 447-449(3); DOI: https://doi.org/10.15212/CVIA.2017.0028, Niya Mileva, Medical University of Sofia, Sofia, Bulgaria and other researchers from Poland and Italy present a case study of misdiagnosed aortic intramural hematoma and the role of intravascular ultrasound imaging in detection of acute aortic syndrome.

Some human cancers may be result of evolutionary accidents, research finds

New research, published in Biological Reviews and conducted by researchers from the University of Liverpool and Escola Superior de Ciências da Saúde (Brasília, Brazil) has found some type of cancers unique to humans may be a result of evolutionary accidents.

Artificial antimicrobial peptides may help fight against drug-resistant bacteria

During the past several years, many strains of bacteria have become resistant to existing antibiotics, and very few new drugs have been added to the antibiotic arsenal.

'Molecular microscope' system for transplant biopsy more effective than conventional methods

A transplant biopsy system that uses gene chips to read molecules is far safer and more effective than existing approaches used for heart transplant biopsies and is showing promising results for lung transplant biopsies, new University of Alberta-led research shows.

Researchers discover how 'junk DNA' plays key role in holding the genome together

Researchers at the University of Michigan Life Sciences Institute and the Howard Hughes Medical Institute have determined how satellite DNA, considered to be "junk DNA," plays a crucial role in holding the genome together.

Biomarker panel can guide future therapeutic decisions for glioma patients

In an article published April 10th in the journal Cell Reports, researchers at the University of São Paulo describe a biomarker panel that could tell physicians which patients diagnosed with glioma, a type of brain cancer, will tend to progress to a more aggressive form of the disease in the event of relapse.

Raising eyebrows came about as humans evolved

Early Homo sapiens had thick bone brows, this made raising eyebrows and a host of other facial expressions difficult for them. With passage of time evolution took its course and the brows smoothened.

Scientists create organoids that could help guide bladder cancer treatment

Researchers have created patient-specific bladder cancer organoids that imitate many of the features of real tumors and may therefore be used to study how cancer evolves.

Study provides systematic view of gene enhancer activity in diverse tumors

At the heart of any cancer diagnosis or treatment are cells. If one thinks of the cell components controlling gene activation as a Russian nesting-doll of gene regulatory layers, within those increasingly smaller tiers are short pieces of non-coding DNA called enhancers.
