Scientists identify nicotinamidase enzyme as new drug target for Leishmaniasis

IRD scientist and their research partners recently identified the key role of nicotinamidase, an enzyme in the parasite Leishmania, essential for its survival but which does not exist in humans. The pathogen is incapable of developing in mammals In the absence of this enzyme. Specific targeting of this enzyme could lead to more effective ways of controlling this neglected tropical disease.

Researchers announce new method to build important heparin drug

Robert Linhardt is working to forever change the way some of the most widely used drugs in the world are manufactured. Today, in the journal Science, he and his partner in the research, Jian Liu, have announced an important step toward making this a reality. The discovery appears in the October 28, 2011 edition of the journal Science in a paper titled "chemoenzymatic synthesis of homogeneous ultra-low molecular weight heparins."

CINJ experts available to discuss risk factors of pancreatic cancer

According to the American Cancer Society, pancreatic cancer is the fifth leading cancer killer in the country, with nearly 44,000 new cases expected in 2011 and more than 37,600 deaths by year's end. In New Jersey alone, an estimated 1,100 deaths are predicted this year due to the disease. The death of Steve Jobs, who suffered from a form of pancreatic cancer, has brought increased attention to the disease in recent weeks.

E. coli asparaginase linked to relapses in ALL patients with special form of ATF5 gene

One of the causes of resistance to cancer treatment in children is now beginning to be elucidated. Acute lymphoblastic leukemia patients with a particular form of the ATF5 gene are at higher risk of having a relapse when treated with E. coli asparaginase, a key chemotherapy drug for this type of leukemia.

Insulin resistance paradox

Obesity and insulin resistance are almost inevitably associated with increases in lipid accumulation in the liver, a serious disease that can deteriorate to hepatitis and liver failure. A real paradox in understanding insulin resistance is figuring out why insulin-resistant livers make more fat. Insulin resistance occurs when the body does a poor job of lowering blood sugars.

Scientists discover gene variants that contribute to early stent thrombosis

In a first-of-its-kind study, researchers from Mount Sinai School of Medicine have discovered several gene variants contributing to early stent thrombosis (ST), a devastating and often deadly complication after coronary stent implantation in people with coronary artery disease.

Complexities of DNA repair

An international team of scientists led by UC Davis researchers has discovered that DNA repair in cancer cells is not a one-way street as previously believed. Their findings show instead that recombination, an important DNA repair process, has a self-correcting mechanism that allows DNA to make a virtual u-turn and start over.

C. sinensis parasite lacks enzymes required for fatty acid biosynthesis

The human liver fluke Clonorchis sinensis affects more than 35 million people in South East Asia and 15 million in China. Infection by this parasite causes clonorchiasis. Repeated or chronic infection can lead to serious disease of the liver, gall bladder or bile ducts, including the frequently fatal bile duct cancer - cholangiocarcinoma.

Microbiome and its role in gastric and estrogen-related cancers

In the October 20th edition of the journal Cell Host and Microbe, Drs. Claudia Plottel and Martin J. Blaser of the Departments of Medicine and Microbiology at NYU Langone Medical Center, and the Department of Biology at New York University, present a model for understanding how cancer evolves in humans based on an understanding of the bacteria living in our body, the microbiome.

No unique link between first-trimester ACE inhibitor use and birth defects

Women who take angiotensin-converting enzyme (ACE) inhibitors to treat high blood pressure in the first trimester of their pregnancies are at no greater risk of having babies with birth defects than are women who take other types of high blood pressure medication or who take no blood pressure drugs, according to a new study from the U.S. Department of Health and Human Services' (HHS) Agency for Healthcare Research and Quality.

Tenofovir gel shows promise against HSV infection

HIV infection is commonly associated with other sexual infections, such as herpes simplex virus (HSV). Infection with HSV facilitates the risk of HIV infection and negatively impacts the clinical course of HIV disease. Therefore, it would be highly beneficial to identify multi-faceted microbicide compounds that are efficient against HIV-1 and other sexually transmitted infections.
