Heart can be turned ON and OFF by a light switch
Millions of people around the world suffer from some degree of cardiac arrhythmia, wherein a person’s heart beats too slowly, too quickly or at irregular intervals. Such heart rhythm problems can cause a shortness of breath, fainting and, in worst-case scenarios, death.
The good news is devices like pacemakers and defibrillators allow doctors to introduce electrical signals to set patients’ hearts at regularly timed beats.
But these small mechanical devices come with risks.
Patients must undergo invasive surgical procedures to permanently implant the devices, which can cause cardiac tissue damage. There are other challenges too, such as lifestyle limitations and the occasional battery malfunction.
Oscar Abilez, a cardiovascular physician with a doctorate in bioengineering is working with a team of Stanford scientists to develop a novel biological pacemaker – one that controls the human heart with light.
Quick-thinking doctor uses mentor’s Whatsapp tips to save labourer’s hand
Boisar doctor sends photos of the nearly-severed hand to his mentor, who then guides him through a complex 10-hour-long microsurgery.
Besides performing a microsurgery that could only be done in a super-speciality hospital, a Boisar-based orthopaedic surgeon used sheer presence of mind to save the nearly severed hand of a labourer after it was almost sliced off by a saw machine.
Since he had never handled such a case, Dr Jitendra Patil, who owns a hospital in Boisar, immediately called up his mentor. Dr Hemant Patankar, orthopaedic head of department at Ghatkopar’s Rajawadi Hospital, directed him on how to go about the delicate operation going by photographs and details of the wound that Dr Patil sent him via smartphone messenger WhatsApp.
Chennai doctor uses Google Glass to air operation live
On Tuesday, Lifeline Hospitals in Chennai live-streamed an upper gastro-intestinal laparoscopy procedure on a 45-year-old man and a hernia repair on a 42-year-old woman to medical students seated two blocks away using Google Glass.
“It felt like I was glancing at my rearview mirror while driving. I was focusing on the surgeries and talking to my students at the same time. At one point, I stopped feeling it was an external device,” said Dr J S Rajkumar, chief surgeon of the hospital.
Cancerous tumor sniffing intelligent knife designed
An “intelligent” knife that can sniff out tumors to improve cancer surgery has been developed by scientists.
Removing cancerous tumors from a patient is a very precise science, and it can be very difficult for surgeons to determine where tumors begin and end.
The Imperial College London team hope to overcome the dangerous and common problem of leaving bits of the tumour in a patient, which can then regrow.
Geo Tag: knowing your location.
A few days back I uploaded a photo on Facebook. After uploading, I went on to add the location of the photo and Facebook offered a suggestion as to where the photo was taken. I looked at the first option; it was the exact location where I had clicked the pic.
facebook detecting the exact location of the place where the photo was taken.
I was astonished. I knew that there would be some complex code that determined the location but to any layman it would seem like magic. I began to wonder what this amazing code might be because recognizing a location from its environment would be a herculean task.
Pressure Ulcers prevented using mattress sensing MAP system
Wellsense of Nashville, Tennessee is a company that has developed a monitoring technology that helps prevent pressure ulcers in bed ridden patients in a clinical setting.
The MAP System involves a special electronic sheet placed over a mattress that has thousands of sensors that in real time detect the pressure distribution of the patient’s body over the bed.
Researchers Create Inner Ear from Stem Cells
Researchers have converted embryonic stem cells from mice into structures of the inner-ear. The breakthrough will help with cellular therapy and new drugs for inner-ear disorders.
Scientists from Indiana University have transformed mouse embryonic stem cells into key structures of the inner ear.
These are stem-cell-derived sensory hair cells (in red) with hair bundles (green).
Cellular nuclei are shown in blue.
Human liver grown in mouse from stem cells.
scientists in Japan have created small human livers from stem cells and transplanted them into mice.
The transplanted livers were able to take on normal liver functions such as clearing toxins from the blood of the mice. This is believed to be the first successful generation of a functional organ from stem cells.
Scientists have used stem cells to grow tiny functioning livers and successfully implanted them in mice.
