New fruit fly model study reveals metabolic pathway that can be targeted to treat FXS patients

Fragile X syndrome (FXS) is the most common genetically inherited cause of intellectual disability in humans. New research shows how the hormone insulin -- usually associated with diabetes -- is involved in the daily activity patterns and cognitive deficits in the fruitfly model of FXS, according to a new study from the Perelman School of Medicine at the University of Pennsylvania published online this month in Molecular Psychiatry in advance of the print issue.

Derivatives of female sex hormones can influence natural melanin production, study suggests

When skin cells responsible for pigmentation are exposed to estrogen or progesterone, the cells respond by adjusting their melanin production, resulting in either skin darkening or lightening. Although pregnant women often experience alterations in skin pigmentation, the reason for the changes has long puzzled physicians.

OSMR gene plays key role in driving growth of glioblastoma tumors

Glioblastoma is the most aggressive type of brain tumor in adults. Unfortunately, there are no effective treatments for the disease. On average, patients succumb just 16 months after diagnosis.

New study explores factors that affect Medicare patient’s adherence to psoriasis biologic therapies

About half of Medicare patients who start taking biologic therapies for moderate to severe plaque psoriasis stop within a year, according to a new study led by researchers from the Perelman School of Medicine at the University of Pennsylvania.

Hearing aid use improves cognitive function in hearing-impaired older adults

A study conducted by researchers at Columbia University Medical Center found that older adults who used a hearing aid performed significantly better on cognitive tests than those who did not use a hearing aid, despite having poorer hearing. The study was published online in the American Journal of Geriatric Psychiatry.

Children living closer to major roadways have increased risk of lower lung function, study finds

According to new research led by Beth Israel Deaconess Medical Center pulmonologist and critical care physician Mary B. Rice, MD, MPH, improved air quality in U.S. cities since the 1990s may not be enough to ensure normal lung function in children. The findings were recently published in the American Journal of Respiratory and Critical Care, a journal of the American Thoracic Society.

Study shows canine AD shares significant features of human version

Atopic dermatitis (AD), a chronic inflammatory skin condition and the most common form of eczema, is estimated to afflict as much as 10 percent of the U.S. population, and is much more common now than it was 50 years ago. Veterinary clinical estimates also show that approximately 10 percent of dogs have atopic dermatitis.

Meta-analysis supports combination therapy for PAH patients

A meta-analysis shows that clinical worsening is significantly less likely in patients with pulmonary arterial hypertension if they are given combination treatment, rather than monotherapy.

Newly identified molecular pathway could lead to new treatments for reflux, incontinence disorders

Researchers at UMass Medical School have identified a new molecular pathway critical for maintaining the smooth muscle tone that allows the passage of materials through the digestive system.

Newly developed smartphone application may potentially benefit low-vision users

Researchers from the Schepens Eye Research Institute of Massachusetts Eye and Ear/Harvard Medical School have developed a smartphone application that projects a magnified smartphone screen to Google Glass, which users can navigate using head movements to view a corresponding portion of the magnified screen. They have shown that the technology can potentially benefit low-vision users, many of whom find the smartphone's built-in zoom feature to be difficult to use due to the loss of context. Their results are published online in the journal IEEE Transactions on Neural Systems and Rehabilitation Engineering.

Scientists derive first molecular model of critical transporter at blood-brain barrier

Scientists from Duke-NUS Medical School have derived a structural model of a transporter at the blood-brain barrier called Mfsd2a. This is the first molecular model of this critical transporter, and could prove important for the development of therapeutic agents that need to be delivered to the brain --- across the blood-brain barrier. In future, this could help treat neurological disorders such as glioblastoma.

Type 2 diabetes can lead to hearing impairment

A review of studies of possible linkages between type 2 diabetes and hearing impairment concludes there is compelling evidence that diabetes can damage the auditory system, and that clinicians should include hearing testing in managing type 2 diabetes. The survey results were published in an article titled, "Type 2 Diabetes and Hearing Impairment" in the journal, Current Diabetes Reports.

Researchers develop real-time single molecule electronic DNA sequencing platform

Researchers from Columbia University, with colleagues at Genia Technologies, Harvard University and the National Institute of Standards and Technology report achieving real-time single molecule electronic DNA sequencing at single-base resolution using a protein nanopore array.

Under-expressed miR-9 gene may contribute to schizophrenia risk

By turning skin cells into brain neurons, researchers at the Icahn School of Medicine at Mount Sinai have identified that certain tiny molecules aiding in gene expression, known as microRNAs (miRNAs), are under-expressed in the brains of the 14 schizophrenia patients they studied. Their findings, published online today in the journal Cell Reports, show that one of these molecules, a miRNA known as miR-9, is a risk factor that controls the activity of hundreds of genes.

Study reveals best ways to reduce substance use among African Americans

Cocaine use has increased substantially among African Americans in some of the most underserved areas of the United States. Interventions designed to increase connection to and support from non-drug using family and friends, with access to employment, the faith community, and education, are the best ways to reduce substance use among African Americans and other minorities in low-income, resource-poor communities, concludes a study led by a medical anthropologist at the University of California, Riverside.

Study indicates that resolvin D1 has anti-arthritic properties

Rheumatoid arthritis (RA) is a debilitating autoimmune disorder that is characterized by the accumulation of inflammatory cells within the fluid of the joints. Current therapeutic strategies mostly serve to ease pain and rarely are able to reverse damage or resolve inflammation.

Study finds low prevalence of vascular risk among Southwest US population

In a newly published, pilot study in the journal Ethnicity & Disease, researchers report a relatively low prevalence of vascular risk among participants of the Southwest Heart Mind Study, especially among those treated for hypertension and hyperlipidemia despite overweight and obesity.

CUMC researchers identify new neurodevelopmental syndrome

A multicenter research team led by Columbia University Medical Center has discovered a new neurodevelopmental syndrome and the genetic mutations that cause it. The discovery is an important step toward creating targeted therapies for individuals with this syndrome, which causes severe developmental delays, abnormal muscle tone, seizures, and eye complications.

Microtubules affect mechanics of beating heart, study finds

On top of the meaning and mystery that humans heap on the heart, it is first and foremost, a muscle. And one that beats about once a second for a person's entire life, with no rest. Given its vital importance, it's ironic researchers have only recently made direct observations of its subcellular parts in motion.
