Scientists report big improvements in HIV vaccine production

Research on HIV over the past decade has led to many promising ideas for vaccines to prevent infection by the AIDS virus, but very few candidate vaccines have been tested in clinical trials. One reason for this is the technical difficulty of manufacturing vaccines based on the envelope proteins of […]

U-M discovery helps build a better target for anticancer drug discovery

In one of many ways cancer attacks the body, it activates an enzyme that is typically absent in normal, healthy cells. The enzyme is also present in stem cells. When stem cells in our bodies divide, chromosomes within those cells, which carry our genetic material, shorten. If they become too […]

Chemistry breakthroughs open new doors to drug developers and cancer researchers

Two independent chemistry breakthroughs have opened a plethora of doors that were previously locked to drug developers and cancer researchers. The discoveries, which involved adding new materials to a previously unstable chemical scaffold and building molecules onto the “pigments of life”, will also offer new possibilities to molecular engineers, materials […]

Uncovering the early origins of Huntington's disease

With new findings, scientists may be poised to break a long impasse in research on Huntington’s disease, a fatal hereditary disorder for which there is currently no treatment. One in 10,000 Americans suffer from the disease, and most begin to show symptoms in middle age as they develop jerky movements—and […]

Could a Protein Called Klotho Block Dementia and Aging?

Neurologist and neuroscientist Dena Dubal, MD, PhD, is taking an innovative approach to battling neurodegenerative diseases like Alzheimer’s disease and dementia. Rather than trying to understand the specific mechanisms that cause each disease, she took a step back and asked, “What do all these conditions have in common?” The answer: old […]

Short-course radiation may be preferable for some skin cancer patients

A recent Penn State College of Medicine physician’s study review suggests that shorter courses of radiation are preferable to longer ones for older patients receiving treatment for slow-growing skin cancers. Skin basal and squamous cell cancers are common among patients over 60 years old and are rarely fatal. These cancers — which […]

Women become happier when men die

Growing old is not easy. Your mental health is likely to suffer too just because you have to notice your body fall apart. Furthermore, you become excluded from the normal social life and it can be very painful. However, now scientists say that 85 year old women are actually happier […]

Sleep apnoea may increase the risk of the Alzheimer’s disease

Sleep apnoea is a bizarre condition when people stop breathing when sleeping or their breathing becomes really shallow. It can get so bad that people experience hypoxia, cannot get a good night sleep and sometimes have to get treatment. Now scientists from the University of Queensland found that low levels […]

Magnet-based drug delivery system shows promise for cancer treatment

A team of researchers at the University of Georgia has developed a non-invasive method of delivering drugs directly to cancerous tissue using magnetic forces, a form of treatment that could significantly reduce the toxic side effects of chemotherapy. “We showed that we can deliver anti-cancer drugs exactly in the area […]

UCI scientists develop new chemical tool to study RNA structures inside cells

University of California, Irvine scientists have created a new chemical tool that can analyze RNA structures within living cells. The technique could facilitate a better grasp of how RNA structures fold and form in cells, as well as help in the design of drugs targeting RNA. Robert Spitale, assistant professor […]

Treating sleep apnoea could reduce dementia risk

Inadequate oxygen levels during sleep can damage the brain and increase the risk of developing Alzheimer’s disease, University of Queensland researchers have found. Scientists from UQ’s Queensland Brain Institute and School of Biomedical Sciences are now initiating a clinical study of patients with sleep apnoea to determine whether treatment lowers the risk of developing […]

What social programmes work the best to include older people?

We live in a strange world. Everyone is ageing and it is accepted, but somehow older people find themselves excluded from the society.  So much so that World Health Organization is promoting programmes that encourage age-friendly environments. Now scientists from Newcastle and Liverpool universities conducted a research to evaluate effectiveness […]

Taking multiple Rx drugs raises risks for aging adults with and without HIV

Taking five or more prescription medications increases the risk of hospitalization and death in older adults infected with HIV and comparable adults without HIV. The findings of this Yale-led study highlight the potential risks of prescribing additional drugs to patients with multiple medical conditions. The research was published online in the […]

Stealth Virus for Cancer Therapy

Scientists from the University of Zurich have redesigned an adenovirus for use in cancer therapy. To achieve this they developed a new protein shield that hides the virus and protects it from being eliminated. Adapters on the surface of the virus enable the reconstructed virus to specifically infect tumor cells. […]

Light-triggered nanoparticles show promise against metastatic cancer

A new anti-cancer strategy wields light as a precision weapon. Unlike traditional light therapy — which is limited to the skin and areas accessible with an endoscope — this technique can target and attack cancer cells that have spread deep inside the body, according to researchers at Washington University School […]

Potential new treatment for advanced cancers

The European Cancer Stem Cell Research Institute, based with Cardiff University, has repurposed a current cancer therapy, TRAIL, to find a new treatment for advanced cancers that are resistant to anti-hormone therapy. Up to 75% of women diagnosed with breast cancer will have a cancer driven by oestrogen signalling and […]

How fetal infections lead to adult heart disease

Recent studies indicate that infants born prematurely have a higher risk of developing heart disease later in life. Now, researchers at the University of Washington School of Medicine in Seattle have shown that, in preterm animal models, inflammation due to infection can disrupt the activity of genes crucial for normal […]

Nerve cells play a crucial role in healing wounds

Wound healing process is something we all are familiar with. The wound fills up with blood, which coagulates and seals it. Then new cells have to rebuild what was lost. However, there are many various cells in our skin and their relation in wound healing process is only partially understood. […]

Boosting Sirt4 gene activity extends healthy lifespan in fruit flies

A new study on the mechanics of aging and longevity finds that fruit flies inhibited from producing the protein Sirt4 — which is also found in humans — are short-lived, while flies modified to make extra Sirt4 are long-lived. In addition, flies lacking Sirt4 display increased sensitivity to starvation, decreased fertility […]

New Approach Attacks 'Undruggable' Cancers from the Outside In

Cancer researchers have made great strides in developing targeted therapies that treat the specific genetic mutations underlying a patient's cancer. However, many of the most common cancer-causing genes are so central to cellular function throughout the body that they are essentially 'undruggable'. Now, researchers at UC San Francisco have found […]
