Parenting skills tied to reduced inflammation in low-income children

EVANSTON, Ill. --- A new Northwestern University study suggests that an intervention focused on strengthening families can reduce inflammation, a chronic over activation of parts of the immune system that is important for long-term health.

Children of low socioeconomic status (SES) often experience such inflammation and poorer health at all stages of life than their more advantaged peers -- from lower birth weights at infancy to higher rates of age-related cardiovascular disease and cancer.

Louisiana Tech University professor presents at International Bioprinting Congress

RUSTON, La. – Dr. Mark DeCoster, the James E. Wyche III Endowed Professor in Biomedical Engineering at Louisiana Tech University, will present as an invited speaker at the International Bioprinting Congress, July 24-25 at the Biopolis Research and Development Center in Singapore.

Try, try again? Study says no

CAMBRIDGE, MA -- When it comes to learning languages, adults and children have different strengths. Adults excel at absorbing the vocabulary needed to navigate a grocery store or order food in a restaurant, but children have an uncanny ability to pick up on subtle nuances of language that often elude adults. Within months of living in a foreign country, a young child may speak a second language like a native speaker.

UCI researchers find epigenetic tie to neuropsychiatric disorders

Irvine, Calif., July 21, 2014 — Dysfunction in dopamine signaling profoundly changes the activity level of about 2,000 genes in the brain's prefrontal cortex and may be an underlying cause of certain complex neuropsychiatric disorders, such as schizophrenia, according to UC Irvine scientists.

This epigenetic alteration of gene activity in brain cells that receive this neurotransmitter showed for the first time that dopamine deficiencies can affect a variety of behavioral and physiological functions regulated in the prefrontal cortex.

Study offers new clues about the source of racial health disparities

A first-of-its-kind study by researchers at USC and Loyola Marymount University (LMU) has found evidence that the persistent health disparities across race may, in part, be related to anxiety about being confronted by negative racial stereotypes while receiving healthcare.

Mothers of children with autism benefit from peer-led intervention

Peer-led interventions that target parental well-being can significantly reduce stress, depression and anxiety in mothers of children with disabilities, according to new findings released today in the journal Pediatrics.

In a first-of-its-kind study, researchers from Vanderbilt University examined two treatment programs in a large number of primary caregivers of a child with a disability. Participants in both groups experienced improvements in mental health, sleep and overall life satisfaction and showed less dysfunctional parent-child interactions.

Philosopher uses game theory to understand how words, actions acquire meaning

MANHATTAN, KANSAS -- Why does the word "dog" have meaning? If you say "dog" to a friend, why does your friend understand you?

Kansas State University philosopher Elliott Wagner aims to address these types of questions in his latest research, which focuses on long-standing philosophical questions about semantic meaning. Wagner, assistant professor of philosophy, and two other philosophers and a mathematician are collaborating to use game theory to analyze communication and how it acquires meaning.

Motoneuron-like cell transplantation and GDNF delivery for repair of SCI

Adipose-derived stem cells-transdifferentiated motoneurons after transplantation can integrate in the host cord. However, cell survival has been restricted by a lack of ideal environment for nerve cell growth.

The development of blood-retinal barrier during astrocyte/vascular wall cell interaction

There is evidence that astrocytes are closely related to the development and formation of retinal vessels. Dysfunction of astrocytes is an important cause of many retinal vascular disorders and blood-retinal barrier. Huanling Yao, Institute of Neurobiology, College of Life Science, Henan University, China, investigated development of the retinal vascular system and formation of the blood-retinal barrier in mice using immunofluorescence staining, gelatin-ink perfusion, and transmission electron microscopy.

Using a novel scaffold to repair spinal cord injury

Dr. Ning Yuan, Beijing Jishuitan Hospital, China and his colleagues, developed a novel neural stem cell scaffold that has two layers: the inner loose layer and the outer compact layer. The loose layer was infiltrated with a large amount of neural stem cells before it was transplanted in vivo. Thus a plenty of neural stem cells can be provided at the target spinal cord site. The loose layer was adhered to the injured side and the compact layer was placed against the lateral side. The compact layer has very small holes, so it can prevent ingrowth of adjacent scar tissue.

Using a deacetyl chitin conduit and short-term electrical stimulation for PNI

Previous studies have demonstrated that deacetyl chitin conduit nerve bridging or electrical stimulation shows therapeutic effect on peripheral nerve injury (PNI). Dr. Peixun Zhang, Peking University People's Hospital, China and his team bridged the injured right rat sciatic nerve using a deacetyl chitin conduit combined with electrical stimulation (0.1 ms, 3 V, 20 Hz, for 1 hour).

Study links enzyme to Alzheimer's disease

Unclogging the body's protein disposal system may improve memory in patients with Alzheimer's disease (AD), according to a study from scientists at Kyungpook National University in Korea published in The Journal of Experimental Medicine.

Missing sleep may hurt your memory

EAST LANSING, Mich. --- Lack of sleep, already considered a public health epidemic, can also lead to errors in memory, finds a new study by researchers at Michigan State University and the University of California, Irvine.

The study, published in the journal Psychological Science, found participants deprived of a night's sleep were more likely to flub the details of a simulated burglary they were shown in a series of images.

Diagnostic criteria for Christianson Syndrome

Because the severe autism-like condition Christianson Syndrome was only first reported in 1999 and some symptoms take more than a decade to appear, families and doctors urgently need fundamental information about it. A new study that doubles the number of cases now documented in the scientific literature provides the most definitive characterization of CS to date. The authors therefore propose the first diagnostic criteria for the condition.

New research links bad diet to loss of smell

TALLAHASSEE, Fla. — Could stuffing yourself full of high-fat foods cause you to lose your sense of smell?

A new study from Florida State University neuroscientists says so, and it has researchers taking a closer look at how our diets could impact a whole range of human functions that were not traditionally considered when examining the impact of obesity.

"This opens up a lot of possibilities for obesity research," said Florida State University post-doctoral researcher Nicolas Thiebaud, who led the study examining how high-fat foods impacted smell.
