Living well, living longer with HIV-AIDS

A nurse scientist at Case Western Reserve University is further expanding her research on aging-related health challenges increasingly faced by people living longer with HIV-AIDS. Allison Webel, an associate professor at the Frances Payne Bolton School of Nursing at Case Western Reserve, has for more than a decade focused on […]

Map showing gene interactions could lead to new cancer therapies

Nearly 150,000 cancer-related deaths can be attributed annually to Epstein-Barr (EBV) virus, in part because of the lack of effective treatment options. Now, a research team has created the first comprehensive map of interactions between the genes of the virus and host cells in EBV-associated cancers, knowledge that could lead […]

Gene Therapy Update: Remembering Jesse Gelsinger

Like the mythological phoenix bird, gene therapy has risen from the ashes and is spreading its wings. September 17 marked 20 years since the death of 19-year-old Jesse Gelsinger in a gene therapy trial. That tragedy halted the fledgling field, with the outlook worsening when, soon after, boys with an […]

Immunologists identify T cell homing beacons for lungs

Scientists have identified a pair of molecules critical for T cells, part of the immune system, to travel to and populate the lungs. A potential application could be strengthening vaccines against respiratory pathogens such as influenza. The findings were published online in Journal of Experimental Medicine. Much research on immunity […]

Study finds age may hinder cancer development

A new study, published in Aging Cell, has found that human ageing processes may hinder cancer development. Ageing is one of the biggest risk factor for cancer. However, the biological mechanisms behind this link are still unclear. Each cell in the human body is specialised to carry out certain tasks and […]

U of A researchers move closer to ‘magic’ cancer treatment

Imagine cancer treatment without chemotherapy, radiation or surgery. Just a small aspirin-like pill. Sound like magic? That’s because it kind of is, according to Khaled Barakat, a University of Alberta biophysicist searching for innovative immunotherapies that could help knock out multiple types of cancer simply by empowering the immune system. “We […]

Spotlighting a common female cancer, and a health disparity

Most women now know to how to check for breast cancer.  And a yearly pap smear to check for cervical cancer is de rigueur.  But awareness of endometrial cancer, not so much. That bothers Dr. Kemi Doll, a gynecologic oncologist with the University of Washington School of Medicine. “The truth is, this is […]

Extra amino acid could work wonders

There are 20 amino acids in the standard genetic code. A Rice University professor wants to know what one can do with 21. Rice chemist Han Xiao has landed a $1.8 million National Institutes of Health grant to learn how a custom-designed 21st amino acid could be employed to make life-saving substances — and […]

Patients could stop breathing for a while to make radiation therapy more accurate

Radiation therapy can be a very effective way to treat cancer – tumour are zapped with a very accurate and very sharp beam of radiation. However, despite the machines being incredibly precise, the treatment might be compromised by the patient’s movement. Now scientists from the University of Birmingham demonstrated that […]

Scientists found a way to reactivate ‘tumour suppressor’ genes

You would get cancer all the time, if your body was not ready to react and suppress the starting disease. Immune system recognizes young cancer cells and kills them. Then there are tumour fighting genes, which stop cancer cells from dividing and spreading. Sadly, cancer is a sneaky disease, able […]

Healthy organelles, healthy cells

For a long time, the contents of cells were thought to be fairly unstructured and chaotic: a mixture of proteins, DNA and a multitude of small metabolic molecules. Although important cellular processes in plants and animals were known to take place in organelles (larger structures enclosed by a membrane, such […]

Our sleeping habits are influenced by gender, age and geographical location

We definitely need sleep. However, some people sleep more than others.That oftentimes depends on how busy and healthy people are. Now scientists from the University of Helsinki  quarter of a million nights of sleep to see what factors influence it the most. The age or participants in this study ranged […]

Study shines light on architecture of kidney disease

A study of 280,000 U.S. veterans including 56,000 African Americans has identified in greater detail than ever before the “genetic architecture” of kidney function and chronic kidney disease (CKD), according to researchers at Vanderbilt University Medical Center and their colleagues. The report, published recently in the journal Nature Communications, is an important […]

Better methods needed for predicting risk of liver disease

While blood samples can reliably identify people with a low risk of developing severe liver disease, better methods are needed in primary care for identifying people in most need of care. These are some of the conclusions of a large registry-based study by researchers at Karolinska Institutet published in the […]

AI identifies genes linked to heart failure

The Queen Mary University of London team applied an artificial intelligence (AI) technique to analyse the heart MRI images of 17,000 healthy UK Biobank volunteers. They found that genetic factors accounted for 22-39 per cent of variation in the size and function of the heart’s left ventricle, the organ’s main […]

Teens sleep 43 more minutes per night after combo of two treatments, study finds

Teenagers got 43 more minutes of sleep a night after a four-week intervention that reset their body clocks and helped them go to bed earlier, a study from the Stanford University School of Medicine has shown. The treatment had two components: brief, early morning flashes of bright, broad-spectrum white light to reset […]

Scientists find potential diagnostic tool, treatment for Parkinson’s disease

In human cell cultures, countering a defect that appears to be nearly universal among patients with Parkinson’s disease prevents death in the cells whose loss causes the disease. Investigators at the Stanford University School of Medicine have pinpointed a molecular defect that seems almost universal among patients with Parkinson’s disease and those […]

Nearly 1 in 3 Patients with Lupus Use Prescription Opioids for Pain

Although there is little evidence that opioids effectively reduce pain from rheumatic diseases, a new study finds nearly one in three patients with lupus uses prescription opioids, often lasting longer than a year. Lupus, a chronic autoimmune disease, often leaves those affected with inflammation and pain throughout the body. “Rheumatic diseases, such […]
