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.

Researchers discover a factor in synapse-building and pruning

Like a gardener who stakes some plants and weeds out others, the brain is constantly building networks of synapses, while pruning out redundant or unneeded synapses. Researchers at The Jackson Laboratory led by Assistant Professor Zhong-wei Zhang, Ph.D., have discovered a factor in synapse-building, also showing that the building and pruning processes occur independent of each other.

Aurora kinase inhibitor may treat neuroendocrine prostate cancer

An international team of researchers led by clinicians at Weill Cornell Medical College have discovered a genetic Achilles' heel in an aggressive type of prostate cancer -- a vulnerability they say can be attacked by a targeted drug that is already in clinical trials to treat other types of cancers.

New treatment may be on the horizon for neuroendocrine prostate cancers

A recent report in Cancer Discovery, a journal of the American Association for Cancer Research, suggests that a new treatment may be on the horizon for neuroendocrine prostate cancers, the most lethal subtype of this disease.

Severity of smoke-inhalation injury may play a role in overall pulmonary inflammatory response

A study of burn patients has found that those who suffered the most severe smoke inhalation also had more inflammation and spent more time on ventilators and in intensive care.

Cancer cells tap into natural recycling system to obtain energy

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that cancer cells tap into a natural recycling system to obtain the energy they need to keep dividing. In a study with potential implications for cancer treatments, Einstein researchers used genetic manipulation to turn off this recycling system within the walls of cells and stop both tumor growth and metastasis.

New 2-DG-ABT combination cancer therapy triggers apoptosis

Researchers at the University of California, San Diego School of Medicine and Kyushu University Medical School say a novel combination of a specific sugar molecule with a pair of cell-killing drugs prompts a wide variety of cancer cell types to kill themselves, a process called apoptosis or programmed cell death.

Researchers identify potential marker for leukemic relapse

The development of simple tests to predict a leukemic relapse in young patients is a step closer thanks to researchers from the Sainte-Justine University Hospital Research Center and the University of Montreal. Approximately 20 percent of young leukemia patients who are treated with stem cells derived from umbilical cord blood will experience leukemic relapse.

SHARPIN protein regulates human cell activity

The research teams headed by Prof. Johanna Ivaska (University of Turku and VTT Technical Research Centre of Finland) and Prof. Marko Salmi (University of Turku and the National Institute for Health and Welfare) have discovered that the SHARPIN protein regulates human cell activity.

Link between NRXN3 gene and impulsivity

Being impulsive can lead us to say things we regret, buy things we really don't need, engage in behaviors that are risky and even develop troublesome addictions. But are different kinds of hastiness and rashness embedded in our DNA? A new study suggests the answer is yes -- especially if you're a man.

Breakthrough in loading gold nanorods into cells could lead to new cancer treatment

Rice University chemists have found a way to load more than 2 million tiny gold particles called nanorods into a single cancer cell. The breakthrough could speed development of cancer treatments that would use nanorods like tiny heating elements to cook tumors from the inside.
