Breath temperature test could identify lung cancer

September 8, 2014 8:43 am | News | Comments

New research in Europe suggests that testing the temperature of breath could be a simple and noninvasive method to either confirm or reject the presence of lung cancer. Many research teams have been looking at the possibility of using breath tests for a number of cancers but this is the first study looking at breath temperature as a marker in lung cancer.

Platelet-like particles augment natural blood clotting for treating trauma

September 8, 2014 8:23 am | by John Toon, Georgia Institute of Technology | News | Comments

A new class of synthetic platelet-like particles could augment natural blood clotting for the emergency treatment of traumatic injuries. The clotting particles, which are based on soft and deformable hydrogel materials, are triggered by the same factor that initiates the body’s own clotting processes.

Researchers turn to plants to help treat hemophilia

September 4, 2014 1:02 pm | by April Frawley Birdwell, Univ. of Florida | News | Comments

Up to 30% of people with the most common form of hemophilia develop antibodies that attack lifesaving protein injections, making it difficult to prevent or treat excessive bleeding. Now researchers have developed a way to thwart production of these antibodies by using plant cells to teach the immune system to tolerate rather than attack the clotting factors.

Handheld scanner could aid complete removal of brain tumors

September 3, 2014 1:09 pm | News | Comments

Cancerous brain tumors are notorious for growing back despite surgical attempts to remove them, and for leading to a dire prognosis for patients. But scientists are developing a new way to try to root out malignant cells during surgery so fewer or none get left behind to form new tumors. The technology relies on a Raman scanner that can read injected nanoprobes.

A “clear” choice for clearing 3-D cell cultures

September 3, 2014 11:40 am | by David Orenstein, Brown Univ. | News | Comments

Because Brown Univ. biomedical engineering graduate student Molly Boutin needed to study how neural tissues grow from stem cells, she wanted to grow not just a cell culture, but a sphere-shaped one. Cells grow and interact more naturally in 3-D cultures than when they’re confined to thin slides or dishes.

A new way to diagnose malaria

September 2, 2014 7:38 am | by Anne Trafton, MIT News Office | News | Comments

Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye and looks under a microscope for the Plasmodium parasite, which causes the disease. This approach gives an accurate count of how many parasites are in the blood, but is not ideal because there is potential for human error.

From nose to knee: Engineered cartilage regenerates joints

August 28, 2014 11:59 am | News | Comments

Cartilage lesions in joints often appear in older people as a result of degenerative processes, and appear in younger people after injuries and accidents. Such defects are difficult to repair and often require complicated surgery and long rehabilitation times. Researchers in Switzerland have reported that cells taken from the nasal septum are able to adapt to the environment of the knee joint and can thus repair articular cartilage defects.

Smartphone app can detect newborn jaundice in minutes

August 27, 2014 11:40 am | by Michelle Ma, Univ. of Washington | News | Comments

Newborn jaundice: It’s one of the last things a parent wants to deal with, but it’s unfortunately a common condition in babies less than a week old. Skin that turns yellow can be a sure sign that a newborn is jaundiced and isn’t adequately eliminating the chemical bilirubin. But that discoloration is sometimes hard to see. Researchers have developed a smartphone application that checks for jaundice in newborns.

Breakthrough antibacterial approach could resolve serious skin infections

August 26, 2014 4:30 pm | by Nancy Ambrosiano, Los Alamos National Laboratory | News | Comments

Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria account for 80% of total bacterial infections in humans and are 50 to 1,000 times more resistant to antibiotics than simpler bacterial infections.

Do-it-yourself blood pressure care can beat MDs

August 26, 2014 4:26 pm | by Lindsey Tanner - AP Medical Writer - Associated Press | News | Comments

"Do-it-yourself" blood pressure measurements and medicine changes work better than usual doctor-office care in some patients, a study of older adults in England found. Those who did their own readings at home and adjusted their medicine as needed had healthier blood pressure levels after a year than those who got standard doctors' care.

A surprising new role for natural killer T cells

August 25, 2014 9:25 am | News | Comments

In the past, immune cells were clearly divided into innate cells, which respond to attacks in a non-specific way, and adaptive cells, which learn to recognize new antigens and gain the ability to rapidly react to later attacks. Researchers at RIKEN in Japan have discovered that is not always the case, having found that killer T cells previously thought to be innate, and thus short-lived, can remain in the lung for up to nine months.

Gold Standard for Laparoscopic Surgery

August 22, 2014 2:38 pm | Award Winners

Laparoscopic Surgery was introduced with a goal to reduce morbidities associated with open surgical techniques. Twenty years later, although it has brought much better outcomes across a number of indicators, it still has some significant patient morbidities and mortality risks associated with it. Port site hernia is one such example. No ubiquitous global device-based standard of care developed has been accepted to deal with this issue. neoSurgical’s neoClose brings a simple, accurate technology/device-based solution that can be deployed in less than 30 sec.

Saving Childrens’ Lives

August 21, 2014 4:18 pm | Award Winners

Globally, 22 million infants aren’t receiving basic vaccines and 1.5 million children will die each year from vaccine-preventable diseases before they reach age five. This challenge is further complicated by the fact that most vaccines must be refrigerated, and more than a billion people globally don’t have reliable access to electricity. Vaccination rates are lowest in remote and rural locations. As part of Intellectual Ventures’ Global Good program, Intellectual Venture Labs (IVL) approached Stratos Product Development for help in developing an insulated container to strengthen and extend vaccination services in developing countries.
