Researchers develop RNA aptamers that inhibit HCV replication

Treatments against hepatitis C virus have only been partially successful. A major problem is that antivirals generate drug resistance. Now Seong-Wook Lee of Dankook University, Yongin, Republic of Korea and his collaborators have developed agents that bind to the business end of a critical protein, disabling it so successfully that no resistance has arisen.

Theoretical mathematical models offer insights into therapeutic, prevention strategies for HIV

The first few hours to days following exposure to human immunodeficiency virus can be of critical importance in determining if infection occurs in a patient. But the low numbers of viruses and infected cells at this stage makes it very difficult to study these events in humans or animal models.

CREON Delayed-Release Capsules now available in US for patients with EPI

AbbVie announced that a new, higher-dose capsule of CREON (pancrelipase) Delayed-Release Capsules is commercially available in the United States. The U.S. Food and Drug Administration recently approved CREON in a 36,000 lipase-unit dose to treat patients with exocrine pancreatic insufficiency due to cystic fibrosis, swelling of the pancreas that lasts a long time (chronic pancreatitis), removal of some or all of the pancreas (pancreatectomy), or other conditions.

Scientists develop new chemical method to treat Alzheimer's disease

Scientists at the University of Liverpool and Callaghan Innovation in New Zealand have developed a new chemical approach to help harness the natural ability of complex sugars to treat Alzheimer's disease.

Scientists discover new function of an enzyme that disposes of superfluous proteins

Cells have a sophisticated system to control and dispose of defective, superfluous proteins and thus to prevent damage to the body. Dr. Katrin Bagola and Professor Thomas Sommer of the Max Delbr-ck Center for Molecular Medicine Berlin-Buch as well as Professor Michael Glickman and Professor Aaron Ciechanover of Technion, the Technical University of Israel in Haifa, have now discovered a new function of an enzyme that is involved in this vital process.

Spherical nanoparticles transform into netlike structures at site of cancer

Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer, the team reports in the journal Advanced Materials this week.

New technique may help develop genetic thermometer to assess patients’ health

On May 22, JoVE will publish details of a technique to measure the health of human genetic material in relation to a patient-s age. The method is demonstrated by the laboratory of Dr. Gil Atzmon at New York-s Albert Einstein College of Medicine.

New research identifies mechanism to make cancer cells respond to chemotherapy

Breast cancer characterized as "triple negative" carries a poor prognosis, with limited treatment options. In some cases, chemotherapy doesn't kill the cancer cells the way it's supposed to. New research from Western University explains why some cancer cells don't respond to chemotherapy, and identifies a mechanism to rectify that.

EGFR gums up cell's miRNA-processing machinery under oxygen starvation conditions

Even while being dragged to its destruction inside a cell, a cancer-promoting growth factor receptor fires away, sending signals that thwart the development of tumor-suppressing microRNAs before it's dissolved, researchers reported in an early online publication at Nature.

Researchers explore targeted therapies for prostate cancer

Are certain drugs more effective against some types of prostate cancers than others? Researchers know that not all therapies work for all patients – the next question is to figure out how to match the right treatments with the right patients.

Common type of childhood asthma is not related to allergens and inflammation

Little is known about why asthma develops, how it constricts the airway or why response to treatments varies between patients. Now, a team of researchers at Weill Cornell Medical College, Columbia University Medical Center and SUNY Downstate Medical Center has revealed the roots of a common type of childhood asthma, showing that it is very different from other asthma cases.

Long-term depression linked with life-threatening chronic disease, earlier death

The first symptoms of major depression may be behavioral, but the common mental illness is based in biology — and not limited to the brain. In recent years some studies have linked major, long-term depression with life-threatening chronic disease and with earlier death, even after lifestyle risk factors have been taken into account.

NIH-funded study raises hope for recovery of some adult patients with brain disorder

Scientists have reversed behavioral and brain abnormalities in adult mice that resemble some features of schizophrenia by restoring normal expression to a suspect gene that is over-expressed in humans with the illness.

Johns Hopkins researchers find possible trigger of rheumatoid arthritis

In a series of lab experiments designed to unravel the workings of a key enzyme widely considered a possible trigger of rheumatoid arthritis, researchers at Johns Hopkins have found that in the most severe cases of the disease, the immune system makes a unique subset of antibodies that have a disease-promoting role.
