Mammary stem cells challenge costly bovine disease

Mastitis is the most expensive disease in the dairy industry. Each clinical case can cost a dairy farmer more than $400 and damages both the cow’s future output as well as her comfort. Bovine mastitis is typically treated with antibiotics, but with the potential threat of antimicrobial resistance and the […]

How working dogs are sniffing out cancer

At Penn, collaboration is as ingrained in the culture as innovation. And, it turns out, some teams end up having quite the crew. One specific group—working to detect early stage ovarian cancer—maintains experts spanning obstetrics and gynecology, chemistry, physics, and veterinary care. It also includes human’s best furry friends: dogs. As […]

UVA reveals how a cancer – causing virus clings to human DNA like a bur to a sock

Using a homemade, high-tech microscope, scientists at the University of Virginia School of Medicine have revealed how a cancer-causing virus anchors itself to our DNA. That discovery could pave the way for doctors to cure previously incurable diseases by flushing out viruses, including HPV and Epstein-Barr, that now permanently embed […]

Remote-Control Shoots Laser at Nano-Gold to Turn on Cancer-Killing Immune Cells

A remote command could one day send immune cells on a rampage against a malignant tumor. The ability to mobilize, from outside the body, targeted cancer immunotherapy inside the body has taken a step closer to becoming reality. Bioengineers at the Georgia Institute of Technology have installed a heat-sensitive switch […]

Many Economic Evaluations of Oncotype DX May Have Misleading Conclusions

Research led at the Yale School of Public Health have found that the majority of published papers analyzing the cost-effectiveness of a widely used test for breast cancer used a study design that can increase bias. Oncotype DX, a gene-expression profiling test, is used in clinical care to guide chemotherapy […]

Personalized bio-inks boost healing potential of printable body tissue

But platelets also release so-called growth factors that help repair soft tissues – blood vessels, skin, muscle, tendons – and recruit other cells to speed the healing process. Those capabilities have made platelet-rich plasma an emerging treatment option for certain joint injuries and post-operative therapies. Now researchers from the University […]

Multiple sclerosis may be linked to sheep disease toxin

Exposure to a toxin primarily found in sheep could be linked to the development of multiple sclerosis (MS) in humans, new research suggests. Carried out by the University of Exeter and MS Sciences Ltd., the study has found that people with MS are more likely than other people to have […]

Study explores crash risk among older drivers

While older drivers as a group have a relatively high rate of car crashes, few validated tools exist to evaluate an individual’s crash risk and to help older adults make the life-altering decision to give up their car keys. Aiming to better understand how adults’ crash risk changes over time, […]

Football Scuffles, Auto Injuries May Raise Risk for Parkinson’s

A rear-ender in which the driver’s head slams against the steering wheel or a helmet-to-helmet tussle with an opponent on the football field may increase one’s risk for Parkinson’s disease if concussion results, say researchers from UCSF and the San Francisco Veterans Affairs Medical Center. In their study, which publishes […]

Light at Night Can Disrupt Circadian Rhythms in Children. Are There Long-Term Risks?

A new scientific study shows that exposure of preschool children to bright electric light in the evening suppresses melatonin production almost completely, an important addition to the growing body of research in this area. Melatonin suppression is a marker of disruption of our circadian rhythms. Ten kids, ages 3 to 5, were […]

Mechanism behind neuron death in motor neurone disease and frontotemporal dementia discovered

Scientists have identified the molecular mechanism that leads to the death of neurons in amyotrophic lateral sclerosis (also known as ALS or motor neurone disease) and a common form of frontotemporal dementia. Writing in Cell, the researchers from the University of Cambridge and University of Toronto also identify potential therapeutic targets for these currently incurable […]

Scientists Grow Miniature Human Brains in Mice

Back in 2013, researchers achieved human brain organoids for the first time, which they had eventually managed to induce to form structures like those seen in the brains of foetuses. The problem with the brainy organoids is their short life-span. “In our hands, the organoids stop growing around five weeks,” […]

Epstein-Barr virus protein can “switch on” risk genes for autoimmune diseases

Infection with Epstein-Barr virus (EBV), the cause of infectious mononucleosis, has been associated with subsequent development of systemic lupus erythematosus and other chronic autoimmune illnesses, but the mechanisms behind this association have been unclear. Now, a novel computational method shows that a viral protein found in EBV-infected human cells may […]

Diagnosing, treating neuropathy symptoms in cancer patients not exact science

Most of the roughly 15.5 million cancer survivors in the U.S. receive chemotherapy, and roughly 65 percent develop some degree of the chemotherapy-induced nerve damage known as peripheral neuropathy. Peripheral neuropathy simply means nerves outside of the brain and spinal cord are affected, and symptoms include numbness and tingling in […]

Improved method of delivering anti-cancer drugs

The method involves the use of a new type of a nanotube – a tiny tube used in many applications, including drug delivery. This new type, designed and created by Dr Ben Newland at Cardiff University, is made from a non-toxic polymer called poly(ethylene glycol).  Unlike current nanotubes, which can cause […]

Scientists find some human cancers to be ‘evolutionary accidents’

New research, published in Biological Reviews and conducted by researchers from the University of Liverpool and Escola Superior de Ciências da Saúde (Brasília, Brazil) has found some type of cancers unique to humans may be a result of evolutionary accidents. Cancer is a major cause of death worldwide. But humans are not […]

New disease model to facilitate development of ALS and MS drugs

All of the body’s organs contain macrophages, which, as part of the immune system, consume bacteria and other foreign bodies. However, macrophages are also specialised according to the organ in which they operate; in the brain they are known as microglia, and researchers believe that this specialisation is controlled by […]

Could stem cell therapy be an effective treatment for Friedreich’s ataxia?

The small, pilot study aims to recruit seven people to find out if the bone marrow stem cell mobilising drug, granulocyte-colony stimulating factor (GCSF), could improve blood markers and potentially treat the condition. GCSF, which is commonly used in diseases related to the blood, as well as in healthy people […]

Immune-engineered device targets chemo-resistant lymphoma

Non-Hodgkin lymphoma, a cancer that is diagnosed in the U.S. more than 70,000 times annually, arises from overly proliferating immune cells within the body’s lymph nodes, which are connected to a network of lymph vessels through which lymphatic fluid flows. The most common type of lymphoma is diffuse large B-cell […]
