Simply shining light on ‘dinosaur metal’ compound kills cancer cells

A new compound based on Iridium, a rare metal which landed in the Gulf of Mexico 66 M years ago, hooked onto albumin, a protein in blood, can attack the nucleus of cancerous cells when switched on by light, University of Warwick researchers have found. The treatment of cancer using light, called Photodynamic therapy, is

Study predicts worsening of opioid overdose crisis

A study from investigators at the Massachusetts General Hospital (MGH) Institute for Technology Assessment projects that the opioid overdose epidemic in the U.S. is likely to increase in coming years, and that measures based on restricting access to prescription opioids will have a minimal impact in reducing overdose deaths. In their report published in JAMA

New project launched to consolidate sustainable tuberculosis care

A new Tuberculosis Regional Eastern European and Central Asian Project, referred to as TB-REP 2.0, has been launched. This project for 2019 to 2022, building on the previous TB-REP from 2016 to 2018, will consolidate past achievements and address new and remaining challenges while ensuring continuity. In particular, it will focus on improving tuberculosis (TB)

Scientists find a cellular process that stops cancer before it starts

Just as plastic tips protect the ends of shoelaces and keep them from fraying when we tie them, molecular tips called telomeres protect the ends of chromosomes and keep them from fusing when cells continually divide and duplicate their DNA. But while losing the plastic tips may lead to messy laces, telomere loss may lead

Alleviating flashbacks by playing Tetris

A behavioural intervention procedure including the computer game Tetris could help people with post-traumatic stress disorder (PTSD) to alleviate involuntarily recurring visual memories of traumatic experiences. This is the conclusion reached by a team from Ruhr-Universität Bochum together with a researcher from the Karolinska Institutet in Sweden following a study of 20 inpatients with PTSD.

New material could ‘drive wound healing’

Materials are widely used to help heal wounds: Collagen sponges help treat burns and pressure sores, and scaffold-like implants are used to repair bones. However, the process of tissue repair changes over time, so scientists are developing biomaterials that interact with tissues as healing takes place. Now, Dr Ben Almquist and his team at Imperial

There was no relationship between obesity and poverty — until..

In 1841, Orlando Jones patented, a process that separated corn starch from kernels in what is known as wet milling. One year later, Thomas Kingford opened the first commercial wet milling plant in the States. Corn, an agricultural product dating back at least 6,000 years to the Oaxaca region of Mexico, was a natural fit

After naloxone, when can opioid overdose patients be safely discharged

Naloxone has saved thousands of lives. But can patients be safely discharged from the Emergency Department (ED) just an hour after they receive the medication that curtails drug overdoses? According to the St. Paul's Early Discharge Rule developed in 2000, that's how long providers should observe patients after naloxone treatment, so long as their vital

Potential arthritis treatment prevents cartilage breakdown

Osteoarthritis, a disease that causes severe joint pain, affects more than 20 million people in the United States. Some drug treatments can help alleviate the pain, but there are no treatments that can reverse or slow the cartilage breakdown associated with the disease. In an advance that could improve the treatment options available for osteoarthritis,

New Buzz about a Malaria Prevention Drug

Most malaria drugs are designed to reduce symptoms after infection. They work by blocking replication of the disease-causing parasites in human blood, but they don’t prevent infection or transmission via mosquitoes. What’s worse, the malaria parasite is developing resistance to existing drugs. “In many ways, the search for new malaria drugs has been a search

The vaccine saving the lives of Pacific children

This week, we marked World Pneumonia Day. Pneumonia is the single largest infectious cause of death in children worldwide, and about one-third of all childhood deaths from pneumonia are a result of the pneumococcal bacteria. Sadly, most of the deaths as a result of pneumonia occur in poor children from low and middle-income countries. These

No sweat required: Hypertension treatment mimics effect of exercise

Hypertension researchers at The University of Toledo have shown that by increasing the body's supply of beta hydroxybutyrate, a chemical produced predominantly by the liver, it is possible to regulate high blood pressure without reducing sodium intake or increasing exercise. "Our team found that high salt consumption lowered levels of circulating beta hydroxybutyrate. When we

Eye infection in contact lens wearers can cause blindness

A new outbreak of a rare but preventable eye infection that can cause blindness, has been identified in contact lens wearers in a new study led by UCL and Moorfields Eye Hospital researchers. The research team found a threefold increase in Acanthamoeba keratitis since 2011 in South-East England. Reusable contact lens wearers with the eye

Long-term cooking with coal, wood, or charcoal associated with cardiovascular death

Long-term use of coal, wood, or charcoal for cooking is associated with an increased risk of death from cardiovascular disease, according to a study presented today at ESC Congress 2018.1 Dr Derrick Bennett, study author, University of Oxford, UK, said: "Our study suggests that people who use solid fuels for cooking should switch to electricity

Scientists Create a Mouse That Eats Fat But Doesn’t Get Fat, Possible Treatment for Obesity

Yale scientists set out to create a morbidly obese mouse. They failed miserably. What they found was much more interesting. “We created a mouse that eats fat but doesn’t get fat,” said Anne Eichmann, Ensign Professor of Medicine (Cardiology) and Professor of Cellular And Molecular Physiology. The “failure” led Eichmann’s team headed by Associate Research

A Deadly 18th Century Disease Is Making a Comeback in Some of The World’s Richest Countries

In the modern world, we don't think of malnutrition as something found in wealthy countries, like the United States. And yet, a notorious 18th century disease caused by the lack of a single vitamin has been rearing its head in a nation that wastes a quarter of its food every year. Vitamin C was only

Rotavirus vaccine cuts infant deaths by a third in Malawi

The study led by scientists at the University of Liverpool, UCL, Johns Hopkins Bloomberg School of Public Health and partners in Malawi provides the first population-level evidence from a low-income country that rotavirus vaccination saves lives. The findings, published in The Lancet Global Health, add considerable weight to the World Health Organisation’s (WHO) recommendation for
