Portable, Noninvasive Trauma Monitors

Portable, Noninvasive Trauma Monitors 

A portable, noninvasive monitor developed by researchers at the University of Massachusetts Medical School. 

Patients with severe injuries or serious infections run the risk of circulatory shock–a life-threatening condition in which the blood can’t supply tissues with enough oxygen and nutrients. If shock is recognized in time, the patient can be resuscitated with oxygen, intravenous fluids, and medications. But catching shock early is no simple matter. A small infrared sensor currently under development at the University of Massachusetts Medical School promises to detect impending shock earlier than any other noninvasive test.

Robotic System That Will Operate On A Beating Heart

Robotic System That Will Operate On A Beating Heart 

This device lets surgeons attach small anchors to tissue inside a beating heart by compensating for the heart’s movement. 

Fixing the heart is hard. Certain procedures have to be performed on a stationary organ, so the heart is stopped and the patient put on a cardiopulmonary bypass machine. But stopping the heart increases the risk of brain damage. Now researchers at Harvard University and Children’s Hospital Boston are testing a robotic system that could help surgeons perform a common valve repair while the heart beats on. The system uses 3-D ultrasound images to predict and compensate for the motion of the heart so that the surgeon can work on a patient’s mitral valve as it moves.

A Source Of Stem Cells From Men

A Source Of Stem Cells From Men 

 Stem cells from adult human testes normally produce only sperm, but when cultured in the lab with special growth factors, they begin to resemble embryonic stem cells and can differentiate into many adult cell types.

Stem cells from human testes could be used for personalized medicine.  Adult stem cells that behave much like embryonic ones have been isolated from human testes, raising hopes for a new source of versatile stem cells without genetic manipulation or the destruction of embryos. If the new stem cells can be used therapeutically, a simple testicular biopsy could provide the starting material for personalized regenerative medicine.

New Biomaterial Could Help In Knee Cartilage Repair

New Biomaterial Could Help In Knee Cartilage Repair 

 Abnormal Cartilage

A new biomaterial developed by Cartilix, a biotech startup based in Foster City, CA, could dramatically improve the success rate of knee-cartilage repair surgery, making the procedure more accessible to patients with bad knees. The new material, called ChonDux, consists of a polymer hydrogel that, when injected into the knee during surgery, guides the regeneration of cartilage by stimulating repair cells in the body.

Thermography Bra To Detect Breast Cancer

Thermography Bra To Detect Breast Cancer 

If you had been worrying about breast cancer, a bra may be able to warn you in case you develop cancerous tissues. The bra would detect the cancerous growths before they can spread to other areas and help a lot in prognosis, as cancer always needs to be treated early for better results.

Nano-sized “Cargo Ships” Developed To Carry Anti-Cancer Drugs And Markers Through The Body

Nano-sized “Cargo Ships” Developed To Carry Anti-Cancer Drugs And Markers Through The Body 

 The nanometer-sized cargo ships look individually like a chocolate-covered nut cluster, in which a biocompatible lipid forms the chocolate shell and magnetic nanoparticles, quantum dots and the drug doxorubicin are the nuts.

Scientists have developed nanometer-sized ‘cargo ships’ that can sail throughout the body via the bloodstream without immediate detection from the body’s immune radar system and ferry their cargo of anti-cancer drugs and markers into tumors that might otherwise go untreated or undetected.

Tiny Handlike Gripper Could Make It Easier For Doctors

Tiny Handlike Gripper Could Make It Easier For Doctors

A tiny gripper that responds to chemical triggers could be a new tool for surgery.

A tiny handlike gripper that can grasp tissue or cell samples could make it easier for doctors to perform minimally invasive surgery, such as biopsies. The tiny device curls its “fingers” around an object when triggered chemically, and it can be moved around remotely with a magnet.

Surgical Imaging System Turns Cancer Cells Neon

Surgical Imaging System Turns Cancer Cells Neon 

A real-time surgical imaging system (top) displays live video.  Image produced by the new system (bottom) shows a pig’s hind leg after injection of a contrast agent.  

Many cancer patients leave surgery still harboring dangerous tumor cells, while others suffer painful aftereffects because a surgeon has removed too much healthy tissue or nicked a nerve. A new imaging system that highlights cancerous tissue in lurid colors should help surgeons remove every last trace of cancer without harming the surrounding tissue. The system, currently in early clinical trials, uses a new class of contrast agents that emit near-infrared light and can attach to virtually any kind of tissue, cancerous or a healthy–showing surgeons just where to cut.

Patch Designed To Regenerate Damaged Heart

Patch Designed To Regenerate Damaged Heart 

A patch has been designed that regenerates cardiac muscle damaged by a heart attack or heart failure. The mesh patch is made of vicryl, which is a material primarily used for suturing injured tissue while later becoming absorbed by the body.
