FDA urges restriction in injudicious use of antibiotics in livestock

The Food and Drug Administration (FDA) has urged drug companies Wednesday to help limit the use of antibiotics in farm animals. The researchers say that this decades-old practice has contributed to a surge in dangerous, drug-resistant bacteria.

Abnormally low level of SMN protein linked to movement problems in spinal muscular atrophy

An abnormally low level of a protein in certain nerve cells is linked to movement problems that characterize the deadly childhood disorder spinal muscular atrophy, new research in animals suggests.

Study sheds light on malleability of brain's recognition process

No matter what novel objects we come to behold, our brains effortlessly take us from an initial "What's that?" to "Oh, that old thing" after a few casual encounters. In research that helps shed light on the malleability of this recognition process, Brown University neuroscientists have teased apart the potentially different roles that two distinct cell types may play.

Scientists discover mutation limited to brain tissue that causes HMG

Scientists have discovered a mutation limited to brain tissue that causes hemimegalencephaly (HMG), a condition where one half of the brain is enlarged and dysfunctional, leading to intellectual disability and severe epilepsy.

Hi-C sequencing decodes 3-D structure of DNA folds in chromosomes

Chromosomes are strands of DNA that contain the blueprint of all living organisms. Humans have 23 pairs of chromosomes that instruct how genes are regulated during development of the human body. While scientists have developed an understanding of the one-dimensional structure of DNA, until today, little was known about how different parts of DNA are folded next to each other inside the nucleus.

New compound reverses major symptoms associated with FXS

A recent study finds that a new compound reverses many of the major symptoms associated with Fragile X syndrome (FXS), the most common form of inherited intellectual disability and a leading cause of autism. The paper, published by Cell Press in the April 12 issue of the journal Neuron, describes the exciting observation that the FXS correction can occur in adult mice, after the symptoms of the condition have already been established.

Scientists use two different methods to visualize rare CTCs, double positive cells in mBC

New research from The Ohio State University utilizes two different methods to visualize circulating tumor cells (CTCs) as well as other unusual circulating cells with both epithelial and hematopoietic characteristics in metastatic breast cancer.

Screen time linked with obesity in children

Approximately 20 percent of adolescents in the U.S. today are obese or overweight. With the number of obese and overweight younger children close behind, this epidemic has lasting implications for the future.

RiboMed releases multi-marker methylation prognostic test for glioma

RiboMed Clinical Services Laboratory (RCSL), a CLIA-certified subsidiary of RiboMed Biotechnologies, today announced the release of a multi-marker methylation prognostic test for grading gliomas, the most common type of brain cancer.

Study: Stem cells from pelvic bone marrow may help hearts beat stronger

Stem cells from the pelvic bone may help hearts beat stronger. Doctors and other clinicians at the Orlando Health Heart Institute are researching the use of stem cells from pelvic bone marrow to restore tissue and improve heart function after muscle damage from heart attacks.

Transcription factors do not act like an 'on-off' switch

A UNC-led team of scientists has now shown that transcription factors don't act like an 'on-off' switch, but instead can exhibit much more complex binding behavior.

Scientists transform skin cells directly into induced neurons

Until recently, the production of pluripotent "multipurpose" stem cells from skin cells was considered to be the ultimate new development. In the meantime, it has become possible to directly convert cells of the body into one another - without the time-consuming detour via a pluripotent intermediate stage. However, this method has so far been rather inefficient.

Researchers discover a lead on the origin of chronic lymphatic leukaemia

Up until now the causes of the development of chronic lymphatic leukaemia, the most common form of cancer of the blood in Europe, have been unknown. At present a cure is not possible. A research group at the MedUni Vienna led by Christoph Steininger of the University Department of Internal Medicine I has now however discovered a lead on the origin of this disease. Says Steiniger: "This could influence the therapy approach taken in treating chronic lymphatic leukaemia."

Computer modeling supports theory that many dementias spread like prion diseases

A new technique for analyzing brain images offers the possibility of using magnetic resonance imaging (MRI) to predict the rate of progression and physical path of many degenerative brain diseases, report scientists at the San Francisco VA Medical Center and the University of California, San Francisco.

SomaLogic, HUNT Biosciences partner to advance clinical use of cardiovascular biomarkers

HUNT Biosciences and SomaLogic, Inc., today announced a new collaboration to advance the clinical use of protein biomarkers, with an initial focus on the validation of biomarkers for the prediction of cardiovascular events such as strokes, heart attacks, and heart failure.

Scientists map physical architecture of intelligence in the brain

Scientists report that they have mapped the physical architecture of intelligence in the brain. Theirs is one of the largest and most comprehensive analyses so far of the brain structures vital to general intelligence and to specific aspects of intellectual functioning, such as verbal comprehension and working memory.

Breast cancer cells that metastasize to the lung express higher level of PRDX2

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have shown that breast cancer cells that metastasize to the lung express a higher level of the protein peroxiredoxin 2 (PRDX2). The study suggests that the modulation of the levels of this protein could be a new therapeutic strategy to prevent lung metastases.

Amyloid precursor protein appears to regulate its own production

A research team led by the University of South Florida Department of Psychiatry & Behavioral Neurosciences has found that a fragment of the amyloid precursor protein (APP) -- known as sAPP-α and associated with Alzheimer's disease -- appears to regulate its own production.

CLYD gene serves as crucial negative regulator in pulmonary fibrosis

An international team of researchers led by Georgia State University scientists have found a key component in the pathological process of pulmonary fibrosis, a fatal disease for which there is currently no cure.
