Heart transplant patient becomes unexpected ambassador for organ donation

Kevin Riepl arrived at Cedars-Sinai in October 2010, suffering from sudden heart failure that left him fighting for his life. Surgeons swiftly installed a heart pump and later transplanted a new heart, saving his life and turning him into an unexpected ambassador for organ donation.

Scientists identify molecular mechanism central to development of osteoarthritis pain

Researchers at Rush University Medical Center, in collaboration with researchers at Northwestern University, have identified a molecular mechanism central to the development of osteoarthritis (OA) pain, a finding that could have major implications for future treatment of this often-debilitating condition.

New light on how epigenetic signals may function together to determine fate of stem cell

Long-standing research efforts have been focused on understanding how stem cells, cells capable of transforming into any type of cell in the body, are capable of being programmed down a defined path to contribute to the development of a specific organ like a heart, lung, or kidney. Research from the University of North Carolina at Chapel Hill School of Medicine has shed new light on how epigenetic signals may function together to determine the ultimate fate of a stem cell.

Group health approved for PCORI research awards to study care for back pain

Group Health has been approved for two research awards from the Patient-Centered Outcomes Research Institute (PCORI) to study ways to improve care for back pain and to connect patients with community resources. The projects are part of a portfolio of patient-centered comparative clinical effectiveness research that addresses PCORI's National Priorities for Research and Research Agenda.

Key regulator of energy metabolism in cancer cells may play a crucial role in restricting cancer cell growth

Researchers at McGill University have discovered that a key regulator of energy metabolism in cancer cells known as the AMP-activated protein kinase (AMPK) may play a crucial role in restricting cancer cell growth. AMPK acts as a "fuel gauge" in cells; AMPK is turned on when it senses changes in energy levels, and helps to change metabolism when energy levels are low, such as during exercise or when fasting.

Bariatric surgery succeeds when new year resolutions to lose weight fail

For years Blanca Ramirez, like many Americans, started each new year with a resolution to lose weight. But no more. "I lost 55 pounds this year and the weight is rolling off and will stay off," said the 42 year-old, married, mother of three. Ramirez underwent bariatric surgery at Loyola Center for Metabolic Surgery & Bariatric Care in August and has lost 55 pounds in four months.

Novel approach to sort out good or bad mutations associated with lymphoma

As anyone familiar with the X-Men knows, mutants can be either very good or very bad - or somewhere in between. The same appears true within cancer cells, which may harbor hundreds of mutations that set them apart from other cells in the body; the scientific challenge has been to figure out which mutations are culprits and which are innocent bystanders.

Immune-promoting drugs may control recurrent disease

Nearly half of the 700,000 cancer patients who undergo surgical removal of a primary tumor each year suffer a recurrence of their disease at some point, and many of those patients will eventually die from their disease.

Researchers develop unique approach to calpain inhibition

Calpain, a calcium-regulated enzyme, is essential to a host of cellular processes, but can cause severe problems in its overactivated state. It has been implicated as a factor in muscular dystrophy, AIDS, Alzheimer's disease, multiple sclerosis, and cancer. As such, finding and exploiting calpain inhibitors is an important area of research.

Scientists develop two novel model systems for human corneal endothelium

Human corneal endothelial cells (HCEnCs) form a monolayer of hexagonal cells whose main function is to maintain corneal clarity by regulating corneal hydration. Cell loss due to aging or corneal endothelial disorders, such as Fuchs dystrophy, can lead to cornea edema and blindness, resulting in the need for cornea transplants.

New cost-effective, less invasive MRI method for diagnosis of dementia

A new way to use MRI scans may help determine whether dementia is Alzheimer's disease or another type of dementia, according to new research published in the December 26, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Trovagene adds Duke University Health System to worldwide licensees of NPM1 marker for AML

Trovagene, Inc., a developer of transrenal molecular diagnostics, announced it has granted Duke University and Duke University Health Systems a non-exclusive license to incorporate nucleophosmin protein (NPM1) into research and clinical testing services for acute myelogenous leukemia (AML).

Researchers reveal critical role of BRCA1 gene in maintenance of hair follicle stem cells

Our DNA, which stores our genetic information, is constantly submitted to damage. If not properly repaired, DNA damage can lead to cell death, which may in turn lead to tissue exhaustion and ageing, or induce mutations resulting in uncontrolled cell proliferation and cancer. Brca1 is a key gene that mediates DNA repair. Mutations in Brca1 lead to familial and sporadic breast and ovarian cancer in humans.

Study reveals decline in cancer screening rates

The rate of people who seek preventive cancer screenings has fallen over the last ten years in the United States with wide variations between white-collar and blue-collar workers, according to a University of Miami Miller School of Medicine study published on December 27 in the open-access journal Frontiers in Cancer Epidemiology.

Experiencing domestic violence may lead to mental health disorders

Men and women with mental health disorders, across all diagnoses, are more likely to have experienced domestic violence than the general population, according to new research from King's College London's Institute of Psychiatry, in collaboration with the University of Bristol. Previous studies into the link between domestic violence and mental health problems have mainly focused on depression, but this is the first study to look at a wide range of mental health problems in both male and female victims.

Alzheimer's disease or FTLD can be effectively tracked using MRI

When trying to determine the root cause of a person's dementia, using an MRI can effectively and non-invasively screen patients for Alzheimer's disease or Frontotemporal Lobar Degeneration (FTLD), according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania.

Juxtapid receives FDA approval for treatment of rare cholesterol disorder

On Dec. 21, the U.S. Food and Drug Administration approved Juxtapid (lomitapide) to reduce low-density lipoprotein (LDL) cholesterol, total cholesterol, apolipoprotein B, and non-high-density lipoprotein (non-HDL) cholesterol in patients with homozygous familial hypercholesterolemia (HoFH). Juxtapid is intended for use in combination with a low fat diet and other lipid-lowering treatments.

Study on prevalence of coronary atherosclerosis among U.S. soldiers

Among deployed U.S. service members who died of combat or unintentional injuries between 2001-2011 and underwent autopsies, the prevalence of coronary atherosclerosis was 8.5 percent, with factors associated with a higher prevalence of the disease including older age, lower educational level and prior diagnoses of dyslipidemia, hypertension, and obesity, according to a study in the December 26 issue of JAMA.

NORD remembers actor Jack Klugman for support to the Orphan Drug Act

Jack Klugman touched the lives of millions of Americans through his support for what ultimately became the Orphan Drug Act. By portraying on his Quincy, M.E. television show the plight of people with rare diseases with no treatment, Mr. Klugman focused a spotlight on the need for incentives to encourage the development of therapies for small patient populations. He did this in partnership with patients and patient advocates who had been unable to gain national attention until he lent his support.

New light on genome replication

New York University biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome replication and may offer insights into the factors behind the production of abnormal numbers of chromosomes.
