Key method to test compounds for anti-cancer activity in cells flawed, study reveals

The primary method used to test compounds for anti-cancer activity in cells is flawed, Vanderbilt University researchers report May 2 in Nature Methods. The findings cast doubt on methods used by the entire scientific enterprise and pharmaceutical industry to discover new cancer drugs.

Antibiotic treatment may allow bad bugs to flourish

Antibiotics are essential for fighting bacterial infection, but, paradoxically, they can also make the body more prone to infection and diarrhea.

New method may help identify small amounts of nanomaterials in environment samples

It is still unclear what the impact is on humans, animals and plants of synthetic nanomaterials released into the environment or used in products. It's very difficult to detect these nanomaterials in the environment since the concentrations are so low and the particles so small. Now the partners in the NanoUmwelt project have developed a method that is capable of identifying even minute amounts of nanomaterials in environmental samples.

Addition of L19-IL2 can increase radiation therapy-induced immune response against tumours

Radiation therapy not only kills cancer cells, but also helps to activate the immune system against their future proliferation. However, this immune response is often not strong enough to be able to cure tumours, and even when it is, its effect is limited to the area that has been irradiated.

Study provides new insights into how visual information transformed from retina to cortical representations

Neurons in our brain do a remarkable job of translating sensory information into reliable representations of our world that are critical to effectively guide our behavior. The parts of the brain that are responsible for vision have long been center stage for scientists' efforts to understand the rules that neural circuits use to encode sensory information.

Researchers one step closer to understanding disease origin

Researchers are one step closer to understanding the genetic and biological basis of diseases like cancer, diabetes, Alzheimer's and rheumatoid arthritis - and identifying new drug targets and therapies - thanks to work by three computational biology research teams from the University of Arizona Health Sciences, University of Pennsylvania and Vanderbilt University.

Early exposure to pathogens may play pivotal role in immune system development

Exposure to pathogens early in life is beneficial to the education and development of the human immune system.

Novel gene therapy can treat pulmonary hypertension linked with heart failure

Scientists have used a novel gene therapy to halt the progression of pulmonary hypertension, a form of high blood pressure in the lung blood vessels that is linked to heart failure, according to a study led by Roger J. Hajjar, MD, Professor of Medicine and Director of the Cardiovascular Research Center at the Icahn School of Medicine at Mount Sinai.

Feeding breast milk during first month of life may spur brain growth in preterm infants

Feeding premature babies mostly breast milk during the first month of life appears to spur more robust brain growth, compared with babies given little or no breast milk.

Study provides new avenues for improving quality, stability of embryonic stem cells

Research led by the Babraham Institute with collaborators in the UK, Canada and Japan has revealed a new understanding of how an open genome structure supports the long-term and unrestricted developmental potential in embryonic stem cells. This insight provides new avenues for improving the quality and stability of embryonic stem cells - an essential requirement to fulfil their promise in regenerative medicine.

Researchers explore effects of adolescent obesity on cognitive performance in adulthood

The Franco-Mexican research explores the cognitive performance in adulthood when the subjects have been exposed to an obesogenic environment during adolescence.

Scientists reprogram mature blood cells from mice into blood-forming HSCs

Researchers at Boston Children's Hospital have reprogrammed mature blood cells from mice into blood-forming hematopoietic stem cells (HSCs), using a cocktail of eight genetic switches called transcription factors. The reprogrammed cells, which the researchers have dubbed induced HSCs (iHSCs), have the functional hallmarks of HSCs, are able to self-renew like HSCs, and can give rise to all of the cellular components of the blood like HSCs.

Level of salts in the brain play critical role in controlling sleep-wake cycle

Danish research is behind a new epoch-making discovery, which may prove decisive to future brain research. The level of salts in the brain plays a critical role in whether we are asleep or awake. This discovery may be of great importance to research on psychiatric diseases such as schizophrenia and convulsive fits from lack of sleep as well as post-anaesthetization confusion, according to Professor Maiken Nedergaard.

Mitochondrial dysfunction linked to chemotherapeutic resistance in African-American men with prostate cancer

Improper functioning of the mitochondria, a cell's source of energy, may help account for the fact that African-American men with prostate cancer respond poorly to the same conventional therapies provided to Caucasian-American men, according to research led by Dhyan Chandra, PhD, Associate Professor of Oncology in the Department of Pharmacology and Therapeutics at Roswell Park Cancer Institute.

Novel method may enable quick, easy exhaustive analysis of ORs responding to specific odorants

A research group led by Osaka University and Panasonic Corporation developed a method for making a prompt, exhaustive isolation of olfactory receptors (ORs) responding to the odorant of interest. This achievement will enable quick and easy exhaustive analysis of ORs responding to specific odorants, which previously required a great deal of time and effort. These results may be applied to biosensors capable of highly detecting only desired odorants.

New article reviews ability of different stem cells to help restore function after spinal cord injuries

Stem cell therapy is a rapidly evolving and promising treatment for spinal-cord injuries. According to a new literature review, published in the April issue of the Journal of the American Academy of Orthopedic Surgeons, different types of stem cells vary in their ability to help restore function, and an ideal treatment protocol remains unclear pending further clinical research.

New technique can help analyze differences in mandible size and shape linked to gender

The scientific breakthrough, carried out by researchers at UGR and the Spanish National Research Council, is of great significance to the field of biological anthropology. It also has further implications for paleoanthropology, paleodemographics, forensic science and orthodontics, among other disciplines.

Drinking tea flavored with herbs may improve mood and memory

The herbs peppermint, chamomile, rosemary and lavender have been proven to have an impact on mood and memory, with significant benefits displayed for older people, according to new research from Northumbria University.

Elusive brain receptor may play vital role in death of neurons from neurological diseases

Strokes, seizures, traumatic brain injury and schizophrenia: these conditions can cause persistent, widespread acidity around neurons in the brain. But exactly how that acidity affects brain function isn't well understood.

Exposure to fine particulate matter in air can increase risk of cancer-specific mortality

In 2015, the International Agency for Research on Cancer (IARC) published a series of monographs on the evaluation of various carcinogenic risks. In a monograph on air pollution, the organization pointed out the difficulty of assessing the effects of pollution on multiple types of cancers, given their different etiologies, risk factors and variability in the composition of air pollutants in space and time. However, the IARC identified certain key components of air pollution, including particulates.
