Genetic basis of human cortical regionalization similar to patterns found in other mammals, MRI study affirms

A new study using magnetic resonance imaging data of 406 adult human twins affirms the long-standing idea that the genetic basis of human cortical regionalization - the organization of the outer brain into specific functional areas - is similar to and consistent with patterns found in other mammals, indicating a common conservation mechanism in evolution.

Psoriasis may alter cholesterol composition and decrease HDL function

Collaborative research from Perelman School of Medicine at the University of Pennsylvania has shown that psoriasis patients have an increased risk of heart attack, stroke and cardiovascular death, especially if the psoriasis is moderate to severe. Now, Penn researchers have discovered the potential underlying mechanism by which the inflammatory skin disease impacts cardiovascular health.

Budding yeast helps make useful predictions about the biology of individuals

It now only costs a few thousand Euros to sequence the genome of an individual human. However, for most of us, knowing our genome sequence would not be useful. Each human has more than 20 000 genes, and in each of us several thousand of these genes carry mutations.

Non-therapeutic antibiotic usage in food animals creates resistance genes, promotes antibiotic resistance

In a review study, researchers from Tufts University School of Medicine zero in on the controversial, non-therapeutic use of antibiotics in food animals and fish farming as a cause of antibiotic resistance.

Molecular level insights into connection between cancer and diabetes

Developing type 2 diabetes is a lengthy process. An early sign that it has begun is high levels of insulin in the blood. As long as the insulin-producing beta cells are able to compensate for the increased demand, for example when the individual is overweight, the blood sugar levels remain normal. It is not until the capacity for insulin secretion falls below the level needed that type 2 diabetes becomes a fact. The latter stage generally goes quickly, as the stressed beta cells work themselves to death.

New health institute to combat chronic diseases across Maryland

Jay A. Perman, MD, President of the University of Maryland, and Joshua M. Sharfstein, MD, Secretary of the Maryland Department of Health and Mental Hygiene (DHMH), announced today the creation of the Institute for a Healthiest Maryland, a collaboration of support systems that will guide efforts to combat chronic diseases across Maryland.

Study confirms link between CMV and mucoepidermoid carcinoma

An important new study from the Laboratory for Developmental Genetics at USC has confirmed cytomegalovirus (CMV) as a cause of the most common salivary gland cancers. CMV joins a group of fewer than 10 identified oncoviruses - cancer-causing viruses - including HPV.

New Handbook offers overview of social work practice in health care

Increased complexity in health care demands a greater body of knowledge for health social workers. The newly released Handbook of Health Social Work, Second Edition is a key resource for social workers, offering a comprehensive and evidence-based overview of social work practice in health care.

Prox1 gene plays a critical role in formation and maintenance of lymphatic system

A century after the valves that link the lymphatic and blood systems were first described, St. Jude Children's Research Hospital scientists have detailed how those valves form and identified a gene that is critical to the process.

Lentigen, UH Case Medical Center initiate LG631 Phase I trial in glioblastoma

University Hospitals (UH) Case Medical Center, Case Western Reserve University School of Medicine and Lentigen Corporation announced today the initiation of a novel Phase I clinical trial of LG631 gene therapy for the protection of hematopoietic stem cells (HSCs) from the dose limiting toxicity of chemotherapy with Temodar.

Functional MRI illuminates brain networks activated by motion

An estimated 300,000 people in North America are afflicted with dystonia, a disorder characterized by a progressive loss of motor control. Patients with generalized dystonia grapple with involuntary muscle spasms that lead to uncontrolled twisting and turning in awkward, sometimes painful postures.

Scientists discover molecular basis for tamoxifen resistance and potential way to defeat it

In the last three decades, thousands of women with breast cancer have taken the drug tamoxifen, only to discover that the therapy doesn't work, either because their tumors do not respond to the treatment at all, or because they develop resistance to it over time. Now researchers at the University of California, San Francisco (UCSF) have discovered the molecular basis for tamoxifen resistance and found a potential way to defeat it.

Novel gene mutation may increase risk of inherited and sporadic cases of MM

A major international study has identified a novel gene mutation that appears to increase the risk of both inherited and sporadic cases of malignant melanoma, the most deadly form of skin cancer.
