During heart surgery, a highly trained group works as a team.
The cardiovascular surgeon heads up the surgery team and performs the key parts of the surgery.
The assisting surgeons follow the direction of the cardiovascular surgeon.
The cardiovascular anesthesiologist gives you the medicines that make you sleep during the surgery (called anesthesia) and monitors the ventilator, which breathes for you during surgery.
The perfusion technologists run the heart-lung machine.
The cardiovascular nurses are specially trained to assist in heart surgery.
Coronary-artery bypass grafting (CABG), introduced in the 1960s, remains the standard revascularization treatment for complex coronary disease.1 The left internal thoracic artery, with its excellent patency when used as a graft, is the conduit of choice for anastomosis to the left anterior descending coronary artery.
“In some ways, what I do is as much art as it is science,” said Dr. Kirshbom. “Some hearts are missing parts or are put together the wrong way. That’s where the art comes in. Many of our operations require literal rebuilding of cardiac and vascular structures. As one of my colleagues says, each child is a custom job.”

AR (Augmented Reality) is the future of computing, truly. It transcends traditional computing with 2D monitors, mouse and keyboard – and takes us into spatial computing, with 3D holograms and more natural interactions. It’s a whole new way of interacting with digital content in the context of the real world.
Although there are several forms of AR such as mobile and smart glasses, the most advanced and powerful is immersive AR, which is defined as photorealistic, high-resolution, life-size holograms wrapped in a natural interaction paradigm using direct hand manipulation and voice commands. Immersive AR has immense potential to change how we communicate, collaborate and create… enhancing our human interaction in the process.
Healthcare is one of the primary verticals in AR with the most to gain. In healthcare education, medical schools are starting to train a new generation of healthcare professionals using interactive 3D anatomical models – reducing the need for cadavers and significantly improving training and comprehension.
With immersive 3D medical imaging, AR can assist with everything from diagnosis, to patient communication, to collaborative pre-operative planning, to the surgery itself, where 3D MRI/CT scan is overlaid onto the patient. The benefits of 3D medical imaging go well beyond providing high financial value – they represent the future of care-giving.

I know that the title is kind of redundant when mentioning sperm and men in the same line. I wrote it like that to make sure Google crawls it the right way. You know, we humans still way smarter than the Google robots -now, you are supposed to smile, or laugh 🙂
Hiding in plain sight.
Sperm has been having a tough time lately. The concentration per ejaculate is getting lower, scientists have created an artificial version that could one day replace it, and to make matters worse, common household products might affect the quality of the little guys.
“Abnormalities in the formation and function of the atypical centriole may be the root of infertility of unknown cause in couples who have no treatment options available to them,” Tomer Avidor-Reiss, from Toledo’s Department of Biological Sciences, said in a press release.
“It also may have a role in early pregnancy loss and embryo development defects.”
You need two centrioles to make the working centrosome, and until now it was thought that the sperm provided one centriole to the egg, and then duplicated itself.
