New study shows HPV vaccine is reducing rates of genital warts
The human papillomavirus (HPV) vaccine was introduced in Australia in 2007 and New Zealand in 2008 to prevent cervical cancer. It was free for women up to age 26 in Australia and to all women under 20 in New Zealand. This is because 99.7% of cervical cancers are associated with the sexually transmissible infection.

Tropical medicine researchers show malaria prophylaxis is effective when the timing is right
Over 100 million travelers from temperate regions visit malaria-risk areas every year. Some 30,000 become infected with the pathogen Plasmodium falciparum, which is spread by the Anopheles mosquito. Malaria takes its deadly toll on the local population also; especially on high-risk groups such as children and pregnant women. There are various drugs available which can prevent malaria. But some can have serious side effects; others must be taken every day to be effective. Forgetting to take the anti-malaria tablets is currently the biggest risk factor for travelers when it comes to contracting the disease. Researchers headed by Professor Peter Kremsner and Dr. Benjamin Mordmüller at the Institute of Tropical Medicine of the University of Tübingen and the German Center for Infection Research (DZIF) have run the first clinical trials on a new agent, DSM265. In a study supported by MMV (Medicines for Malaria Venture) and the DZIF, healthy volunteers were infected with malaria parasites after taking the new active substance; DSM265 demonstrated a good prophylactic effect. The study has been published in the medical journal The Lancet Infectious Diseases.

Study finds a novel target molecule to help prevent brain damage from hemorrhagic strokes
With more than 130,000 victims nationwide, strokes are among the leading causes of death in the U.S. each year. According to the Centers for Disease Control (CDC), someone in the United States has a stroke every 40 seconds, with a death every four minutes. But for those who survive, strokes can have a devastating impact, from loss of mobility or speech to severe brain damage.

Stem cell transplants offer hope for sufferers of gut disorders
After a baby is born, a souvenir of its months in the womb is usually not long to follow. Its first poo, or meconium, is a lump sum of everything the foetus has ingested for months; a dark sludge, compared by the insomniac readers of parenting forums to engine oil or tar.

Sick stem cells point to better MS drugs
Doctors seeking a cure for an aggressive form of multiple sclerosis keep chasing a mirage: no matter how well a drug works in the lab, it never seems to help many patients in the clinic. But after closely examining stem cells from patients and their families, researchers think they know why the drugs coming out of labs are duds. Neuroscientist Dr. Stephen Crocker, associate professor in the Department of Neuroscience at UConn Health, and colleagues offer an explanation in the Feb. 1 issue of Experimental Neurology.

Gene research gives new insight into pancreatic cancer
One reason pancreatic cancer has a particularly low survival rate is the difficulty in getting drugs to the tumour, but new knowledge of how pancreatic cancer cells invade neighbouring cells could change that.

Video: How animal research helps us understand a devastating condition
OCD can be a devastating condition: therapy and medication often doesn't work, leaving many people unable to hold down a job or a relationship – or even to leave their house. In our series of films, science writer David Adam looks at how research at Cambridge using animals helps us understand what is happening in the brain – and may lead to better treatments.

Team unveils new TGF-beta functions in liver cancer
Recent research results from the TGF-beta and cancer research group at the Bellvitge Biomedical Research Institute (IDIBELL) provide a better understanding of the role of the TGF-beta cytokine in liver cancer. The work, published in Cancer Letters, shows how the TGF-beta cytokine is able to modulate not only the migratory capacity of the hepatocellular carcinoma cell, but also its capacity as a tumor initiator cell.

Immune cell therapy on liver cancer using interferon beta produced with stem cells
Causes of the most common form of liver cancer, hepatocellular carcinoma (HCC), include hepatitis B or C, cirrhosis, obesity, diabetes, a buildup of iron in the liver, or a family of toxins called aflatoxins produced by fungi on some types of food. Typical treatments for HCC include radiation, chemotherapy, cryo- or radiofrequency ablation, resection, and liver transplant. Unfortunately, the mortality rate is still quite high; the American Cancer Society estimates the five-year survival rate for localized liver cancer is 31 percent.
