Researchers reveal how motivation facilitates motor functional recovery in stroke, SCI patients

An effective recovery has been observed in stroke patients and those with spinal cord injuries who have strong vitality and motivation to rehabilitate in clinical practice. However, it was not really clear how motivation facilitates functional recovery in brain science.

Close link between SF3B1 mutation and specific feature of myelodysplastic syndromes

Geneticists have discovered that a gene involved in the modification of ribonucleic acid (RNA) is mutated in a significant proportion of people with a collection of blood cancers called myelodysplastic syndromes.

Researchers identify frequent SF3B1 gene mutation in myelodysplasia

A genomic study of chronic blood cancer - a precursor to leukaemia - has discovered gene mutations that could enable diagnosis using only a blood test, avoiding the need for an invasive and painful bone marrow biopsy.

New research reveals how brain devotes time to reflect on tough choices

Take your time. Hold your horses. Sleep on it. When people must decide between arguably equal choices, they need time to deliberate. In the case of people undergoing deep brain stimulation (DBS) for Parkinson's disease, that process sometimes doesn't kick in, leading to impulsive behavior. New research into why that happens has led scientists to a detailed explanation of how the brain devotes time to reflect on tough choices.

IBN scientists harness ultrasmall peptides to repair spinal disc damage

New ultrasmall peptides that can be used as building blocks for a wide range of regenerative applications such as spinal disc replacement and cartilage repair have been developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute. These peptides spontaneously assemble in water to form hydrogels, which resemble collagen, a major component of connective tissues found in cartilage, ligaments, tendons, bone and skin.

Biochemists reveal interaction between tumor suppressor protein and chaperone

Every cell has thousands of proteins whose activity and lifetime must be regulated to control the cellular life cycle from cell division to cell death. The heat shock protein Hsp90 plays a key role in this process. It is a so-called chaperone, a quality controller, as it were. It monitors and controls the quality and activity of many important signal proteins and helps them take on the right form. When the cell is exposed to high stress levels from heat or a lack of oxygen, Hsp90 is produced in larger quantities to shield its partner proteins from damage.

New technique can precisely locate subthalamic nucleus in Parkinson's patients

Deep brain stimulation stops limb tremors in Parkinson's patients. But positioning the stimulation electrode in the brain must be done very precisely to avoid undesired side-effects.

New research puts an unexpected twist on how mitochondria divide within cells

New research from the University of California, Davis, and the University of Colorado at Boulder puts an unexpected twist on how mitochondria, the energy-generating structures within cells, divide.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

Repeated cocaine use can increase individual's risk of mood disorders

It is well established that a mood disorder can increase an individual's risk for substance abuse, but there is also evidence that the converse is true; substance abuse can increase a person's vulnerability to stress-related illnesses.

Scientists discover nanoparticles can disrupt intracellular transport pathways

Scientists at the Centre of Cancer Biomedicine at the Norwegian Radium Hospital are the first to show that uptake and accumulation of nanoparticles in cells can disrupt important intracellular transport pathways.

Single-molecule imaging reveals how cells prepare to interact with biochemical signals

Researchers at Harvard Medical School have discovered that structural elements in the cell play a crucial role in organizing the motion of cell-surface receptors, proteins that enable cells to receive signals from other parts of the organism.

Study reveals structure of ribosomal assembly intermediate

As part of a joint research effort with the University of Michigan, scientists from the Florida campus of The Scripps Research Institute have for the first time defined the structure of one of the cell's most basic engines, which is required for cell growth, as it assembles from its components.

Study confirms that vitamin D deficiency increases aggressiveness of colon cancer

A study conducted by VHIO researchers confirms that a lack of vitamin D increases the aggressiveness of colon cancer.

Research team reports first genetic sequencing of urothelial carcinoma

In an article published online this week in Nature Genetics, a University of Colorado Cancer Center team in partnership with universities in China and Denmark reports the first genetic sequencing of urothelial (transitional) carcinoma, the most prevalent type of bladder cancer.

Research: p38α MAPK protein plays a role in addiction, depression-like behavior

Researchers studying mice are getting closer to understanding how stress affects mood and motivation for drugs.

New research uncovers role of p38alpha in mood disorders, addiction

Stressful experiences increase addictive drug consumption and can precipitate bouts of anxiety or depression in vulnerable people. Although the mechanisms linking stress and human behaviors are not well understood, animal models of some aspects of these behaviors have been developed and have been used to define some of the molecular events that may be responsible for stress vulnerability in people.

Higher levels of B cells make women more prone to autoimmune diseases

Researchers at National Jewish Health have discovered a type of cell that may contribute to autoimmune disease and suggests why diseases such as lupus, multiple sclerosis and rheumatoid arthritis strike women more frequently than men. The cells, a subset of immune-system B cells, make autoantibodies, which bind to and attack the body's own tissue.

Specific microRNA cluster could play a key role in retinoblastoma development

New research from a team including several Carnegie scientists demonstrates that a specific small segment of RNA could play a key role in the growth of a type of malignant childhood eye tumor called retinoblastoma.

EWS protein detects and corrects DNA damage in Ewing's sarcoma

Researchers from the CRG have discovered that ultraviolet light affects the function of the protein EWS, the mutation of which is responsible for Ewing's sarcoma. The results, to be published on 5th August in the journal Molecular Cell, indicate that the EWS protein has a protective effect on DNA.
