Patients recovering from a stroke can slash their risk of blood clots by wearing a small “half wrist-watch” around their leg, a trial has shown.
A study at Royal Stoke University Hospital found the geko device could reduces the risk of clots compared to standard treatment, is comfortable to wear and could save the NHS cash.
Approved for use on the NHS for other conditions, the geko is a battery-powered, disposable, device designed to increase blood flow in the deep veins of the legs.
In a proof-of-principle study in mice, scientists at Johns Hopkins Medicine report the creation of a specialized gel that acts like a lymph node to successfully activate and multiply cancer-fighting immune system T-cells. The work puts scientists a step closer, they say, to injecting such artificial lymph nodes into people and sparking T-cells to fight disease.
In the past few years, a wave of discoveries has advanced new techniques to use T-cells – a type of white blood cell – in cancer treatment. To be successful, the cells must be primed, or taught, to spot and react to molecular flags that dot the surfaces of cancer cells. The job of educating T-cells this way typically happens in lymph nodes, small, bean-shaped glands found all over the body that house T-cells. But in patients with cancer and immune system disorders, that learning process is faulty, or doesn’t happen.
To address such defects, current T-cell booster therapy requires physicians to remove T-cells from the blood of a patient with cancer and inject the cells back into the patient after either genetically engineering or activating the cells in a laboratory so they recognize cancer-linked molecular flags.
A medical miracle happened about 170 years ago when scientists discovered general anesthesia that enables millions of patients to undergo invasive, life-saving surgeries without pain. However, in spite of decades of research, scientists cannot understand why general anesthesia works.
In a new study published online in Neuron, scientists believe they have discovered the part of the answer. A team of researchers from a Duke University found that several different general anesthesia drugs knock out the patient by hijacking the neural circuitry that the person falls asleep.
They traced this neural circuitry to a tiny cluster of cells at the base of the brain responsible for churning out hormones to regulate bodily functions, moods, and sleep. The discovery is one of the first to indicate a role for the hormones in maintaining the state of general anesthesia and provides valuable insights for generating newer drugs that could put people to sleep with fewer side effects.
The health benefits of raw, unprocessed honey are well known, but in Australia, scientists recently made a startling discovery – that one particular, obscure type of honey is capable of killing just about everything scientists throw at it, including some of the worst bacteria known to man.
The findings were published in the European Journal of Clinical Microbiology and Infectious Diseases (June 2009 edition), and could hold special significance at a time when many of the world’s top antibiotics are failing, especially against resistant “superbugs”.
The honey in question is known as manuka honey, which is produced in New Zealand and also goes by the name of jelly bush honey.
On July 11–12, we will be hosting our second annual Ending Age-Released Diseases conference. This conference focuses on the progress of aging research along with the business and investment side of rejuvenation biotechnology.
Aging research is on the cusp of some major breakthroughs in the battle against age-related diseases, and we invite you to join us for an action-packed event filled with exciting talks and discussion panels featuring some of the leaders of aging research and the biotech business.
Almost one in ten heart attacks and strokes could be avoided if check-ups were targeted at high risk patients, new research has revealed.
People aged 40 and over in England and Wales are currently eligible to have their heart health assessed every five years.
Blood pressure, cholesterol, blood-sugar levels, smoker status, age and family history are factors considered by doctors when working out a person’s chance of having a heart attack or stroke.
Seven months later, following stringent monitoring of signs of immunorejection, the team transplanted a fertilized embryo engineered with IVF into the donor uterus. By 35 weeks, the baby was delivered without complications through a C-section.
The woman was a lucky case. Others who underwent the same procedure experienced immunorejection that prevented them from keeping the womb. The team actually removed the transplanted womb following the successful childbirth, citing that they wanted to currently focus on giving infertile women their first child.
These are still early days for uterine transplants—dead or alive—but the proof-of-concept shows that women who had to previously rely on surrogates may have an alternative way. The team is looking to further refine the protocol, for example, for how much immunosuppressant to give and harvesting the organ as early as possible, to potentially increase success rates.
The idea is to give craftspeople the tools they need to incorporate digital services to the items they’re already making. Poupyrev made it clear that he doesn’t want fundamentally change tried and tested items, like a jacket, into a computer first, and an article of clothing second. He wants to imbue everyday items with digital functionality.
In its final form, Poupyrev envisions clothing, furniture, and accessories that are all connected to the cloud, each providing their own, specialized functionality. Users will interact with screens using their sleeves and pause their music by tapping their glasses. Step trackers will live in our shoes, translators will live in our ears, and medicinal nano-robots could be injected into our blood streams. The very notion of a computer will radically change as little computers get placed into everything.
“This could allow makers to image and create a new world where things are connected and we don’t need keyboards, screens, or mice to interact with computers,” he said. “I’ve been working on this for 20 years and as it’s taken shape I’m realizing that we’re not building an interface. We’re building a a new kind of computer, an invisible computer.”
The brains of decapitated pigs can be partially revived several hours after the animal has died, researchers have revealed, with some of the functions of cells booted back up when an oxygen-rich fluid is circulated through the organ.
The scientists stress that the brains do not show any signs of consciousness – for example, there was no sign that different parts of the brain were sending signals to each other – and that it does not change the definition of death.
But they say they have found a way to prevent brain cells from sustaining irreparable damage as blood stops circulating, and even to restore some of the cells’ functions.
