Routing gene therapy directly into brain



Posted: 06 Dec 2017 02:42 PM PST


A new technique, which could be used to transplant donor-matched hematopoietic stem cells (HSCs) or a patient's own genetically-engineered HSCs into the brain, has been revealed by scientists in a new report.


Parents' reports of children's autism symptoms differ by ethnicity



Posted: 06 Dec 2017 01:23 PM PST


Racial differences in parents' reports of concerns about their child's development to healthcare providers may contribute to delayed diagnosis of autism spectrum disorder (ASD) in black children, according to a study.


3-D mini brains accelerate research for repairing brain function



Posted: 06 Dec 2017 01:23 PM PST


Hospitals are making mini brains from human stem cells, putting researchers on a fast track to repair the nervous system after injury or disease of the brain and spinal cord. Researchers have developed a new system to reduce the time it takes to grow these brain models, which will give them the ability to screen drugs and study what's behind disease-causing mutations more quickly.


Novel regulation of gene expression in brain tumors identified



Posted: 06 Dec 2017 11:23 AM PST


New study results reveal a previously unknown interplay between two key enzymes and a novel understanding of how brain cancer tumors form and spread.


When a common cold may trigger early supportive care



Posted: 06 Dec 2017 11:16 AM PST


A new study shows that in infants who were born severely premature, human rhinovirus infections appear to trigger airway hyper-reactivity, which leads to wheezing, hyperinflation and more severe respiratory disease.


Some video games are good for older adults' brains



Posted: 06 Dec 2017 11:16 AM PST


Playing 3D-platform video games on a regular basis may improve cognitive functions in seniors and increase grey matter in a brain structure called the hippocampus, a new study suggests.


Reading on electronic devices may interfere with science reading comprehension



Posted: 06 Dec 2017 11:16 AM PST


People who often read on electronic devices may have a difficult time understanding scientific concepts, according to researchers. They suggest that this finding, among others in the study, could also offer insights on how reading a scientific text differs from casual reading.


CLOCK gene may hold answers to human brain evolution



Posted: 06 Dec 2017 11:16 AM PST


A gene controlling our biological clocks plays a vital role in regulating human-specific genes important to brain evolution. These findings open new paths of research into how CLOCK proteins produced by the CLOCK gene affect brain function and the processes by which neurons find their proper place in the brain.


Healthy mitochondria could stop Alzheimer's



Posted: 06 Dec 2017 10:25 AM PST


Using a bioinformatics and experimental approach, scientists have found that rendering mitochondria resistant to damage can halt diseases caused by amyloid toxicity, such as Alzheimer's disease.


What's that smell? The advantage of sniffing



Posted: 06 Dec 2017 09:25 AM PST


Breathe in through your nose, and chances are you will feel the air coming in and also smell something nearby. Researchers have discovered how these sensations are kept separate and why sniffing can help identify odors, two problems that have puzzled scientists for years. The study used a system in mice that systematically controls airflow and odor delivery.


Psychosis incidence highly variable internationally



Posted: 06 Dec 2017 09:25 AM PST


Rates of psychosis can be close to eight times higher in some regions compared to others, finds a new study.


Alzheimer's damage in mice reduced with compound that targets APOE gene



Posted: 06 Dec 2017 09:25 AM PST


People who carry the APOE4 genetic variant face a substantial risk for developing Alzheimer's disease. Now, researchers have identified a compound that targets the APOE protein in the brains of mice and protects against damage induced by the Alzheimer's protein amyloid beta. The findings indicate that APOE could potentially be a real target for treatment or prevention.


New method helps identify causal mechanisms in depression



Posted: 06 Dec 2017 09:25 AM PST


People with major depressive disorder have alterations in the activity and connectivity of brain systems underlying reward and memory, according to a new study. The findings provide clues as to which regions of the brain could be at the root of symptoms, such as reduced happiness and pleasure, in depression.


What makes a happy working mom?



Posted: 06 Dec 2017 09:25 AM PST


A happy working mom feels competent in interacting with her child, experiences a sense of freedom and choice in her actions, while having a warm and affectionate relationship with her baby. She is also not too hard on herself about how she is faring as a mother.


Youth who experience violent victimization seek intimate relationships at an earlier age



Posted: 06 Dec 2017 06:22 AM PST


Experiencing violence as an adolescent leads to early romantic relationships and cohabitating, research concludes. On average, they found that victimized youth entered romantic relationships nine months earlier than non-victimized youth.


Is laughter the greatest medicine for cancer patients?



Posted: 06 Dec 2017 06:18 AM PST


Spontaneous humor is used and appreciated by people with cancer and can be a helpful way of dealing with distressing, taboo or embarrassing circumstances, research shows.


Research finds new ways to fight the opioid crisis



Posted: 06 Dec 2017 06:06 AM PST


In the US alone, more than 2 million people struggle with opioid use disorders. Opioids, often prescribed as pain medications, have now become the country's leading cause of drug overdose. But scientists are identifying ways to help combat the epidemic, which include getting people treatment faster, developing safer opioids, and helping patients choose appropriate treatment.


Alarming amounts of noise demand ways to silence noisy hospital environments



Posted: 06 Dec 2017 06:06 AM PST


Spending a night in the hospital is not only stressful, but also loud. The constant beeps, whirrs and alarms ascend to a cacophony that produces anything but a relaxing, restful environment. Researchers summarize the limited number of studies available on hospital noise and discuss the different approaches health care facilities are taking to bring restful repose to patients across the country.


Disorders of the voice can affect a politician's success



Posted: 06 Dec 2017 06:06 AM PST


The acoustics of political speech are known to be a powerful influencer of voter preferences, but vocal disorders can change the qualities of a person's speech, and voice scientists have found that this alters politicians' perceived charisma.


Lack of sleep could cause mood disorders in teens



Posted: 06 Dec 2017 06:06 AM PST


Chronic sleep deprivation -- which can involve staying up late, and waking up early for work or school -- has become a way of life for both kids and adults, especially with the increasing use of phones and tablets late into the night. But this social jet lag poses some serious health and mental health risks: new research finds that for teenagers, even a short period of sleep restriction could, over the long-term, raise their risk for depression and addiction.


New hope for waitlisted patients addicted to opioids



Posted: 06 Dec 2017 06:06 AM PST


As the opioid crisis continues to escalate, the number of people who need treatment for their dependency on heroin or prescription pain killers far exceeds the capacity of available treatment programs. People seeking treatment can wait months or even years for spots in clinics or with certified doctors -- and while they wait, they risk becoming infected with HIV or hepatitis, as well as dying from an overdose.


US and Norwegian trials compare treatment options for opioid dependence



Posted: 06 Dec 2017 06:06 AM PST


The current opioid epidemic is destroying lives, families, and communities. Medication is widely considered to be the most effective treatment, but far too few people who could benefit are actually treated.


Want to listen better? Lend a right ear



Posted: 06 Dec 2017 06:06 AM PST


Listening requires sensitive hearing and the ability to process information into cohesive meaning. Add everyday background noise and constant interruptions, and the ability to comprehend what is heard becomes that much more difficult. Audiology researchers have found that in such demanding environments, both children and adults depend more on their right ear for processing and retaining what they hear.


Brain activity and anxiety symptoms in youth with autism spectrum disorder



Posted: 06 Dec 2017 06:05 AM PST


The error-related negativity (ERN) is a brain signal response to errors that is thought to reflect threat sensitivity and has been implicated in anxiety disorders in individuals without autism spectrum disorder (ASD).


Sexual harassment on the job still carries large impact, study shows



Posted: 05 Dec 2017 02:02 PM PST


Researchers have revisited workplace sexual harassment issues after the initial study was done nearly 20 years ago.


New weakness found in most common childhood malignant brain tumor



Posted: 05 Dec 2017 11:25 AM PST


A new weakness found in medulloblastoma, the most common form of childhood brain tumor, could lead to more personalized medicine and improved treatment for some patients, according to an early study.


Serious risk of mental health crisis in Yemen, say experts



Posted: 05 Dec 2017 06:16 AM PST


Yemenis face serious mental health risks, but the issue is being neglected. In a new study, the researchers reveal how serious the risk to mental health is in Yemen. Yet, mental health services in Yemen are few, and there is little research on the effects of the war on the mental health of the population. The paper also analyzes the long-term costs of failing to respond.


Experimental drug blocks toxic ion flow linked to Alzheimer's disease



Posted: 05 Dec 2017 06:15 AM PST


A new small-molecule drug can restore brain function and memory in a mouse model of Alzheimer's disease. The molecule, called anle138b, works by stopping toxic ion flow in the brain that is known to trigger nerve cell death. Scientists envision that this drug could be used to treat Alzheimer's and other neurodegenerative diseases such as Parkinson's and ALS.
