New research comes to terms with old ideas about canker sores
A burning pain sensation – and treatments that do not work. This is what daily life is like for many of those who suffer from recurrent aphthous stomatitis. Research from the Sahlgrenska Academy now sheds new light on the reasons behind this condition found in the mouth.

New way of screening potential treatments for tuberculosis
Scientists from LSTM's Research Centre for Drugs and Diagnostics (RCDD) have described in a paper published today in Scientific Reports, a new way of screening potential treatments for Tuberculosis (TB) which may assist in the identification and prioritisation of new therapies which could potentially reduce the duration of current TB treatment.

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.

Walking football enriches lives
New research from Abertay University has found organised football sessions have a direct improvement on the lives of people with mental health conditions like schizophrenia and bi-polar disorder.

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.

'Quake brain' affects memory and ability on simple tasks
Cantabrians' cognitive abilities – or their ability to do simple tasks – appear to have been significantly affected by exposure to earthquakes, new research from the University of Otago, Christchurch, has found.

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.

Brain changes in older adults increase risk for scams
Older adults who have been scammed by friends, relatives or strangers seem to behave just like elders who have avoided rip-offs. They are able to balance their checkbooks. They can remember and evaluate information. Their personalities are normal, and their arithmetic is fine.

Study shows how BPA may affect inflammatory breast cancer
The chemical bisphenol A, or BPA, appears to aid the survival of inflammatory breast cancer cells, revealing a potential mechanism for how the disease grows, according to a study led by researchers in the Department of Surgery at Duke University School of Medicine and the Duke Cancer Institute.

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.

Florida's Zika battle plan includes beefing up public labs, mosquito control
South Florida's battle plan for Zika, expected to rebound with the rainy season, includes more boots on the ground to inspect and fumigate for mosquitoes, more lab resources to speed up test turnaround times and the promise of a more collegial collaboration between the federal and state governments.
