Project Taycay

Project Taycay is an initiative of  Quahog Prudent Labs, which aims to monitor and measure body functions regularly so as to keep the user notified of ab-normalization in body functions.

Most cases today is that, patients visit doctors only after a certain symptom bothers them and in so many cases, the patients have seen the doctor at a very critical stage. Keeping  a regular monitor and control of the body functions will help in quickly understanding  the changes in body functions and addressing them instantly

Quahog Prudent range of products aims to build devices for users which can help them monitor their body functions regularly using blood, urine and saliva

Role of Mitochondria in Disease

Maria Konovalenko

Mitochondria and diseaseThere are tree lectures about the mitochondria in my course. Dr. Pinchas Cohen, the Dean of Davis School of Gerontology, talked about the role of mitochondria in disease and pathology.

Mitochondria have essentially three major functions. They are responsible for cellular respiration, integration of apoptotic signals, which means they control cell death, and production of reactive oxygen species (ROS). Mitochondrial function declines with age as a result of accumulated mutations in the mitochondrial DNA. Mitochondrial disfunction is common in diseases, such as diabetes, neurodegenerative pathologies and cancer.

Interestingly, Dr. Cohen mentioned that there were only three Nobel prizes for research in mitochondrial biology. He anticipates that quite soon there will be a Prize awarded to mitochondria research.

Mitochondria are very different in different tissues. They vary in size, numbers, histologically and in proteins they have. Energy production levels also vary quite significantly. This is due to differences in cellular environment…

Forever Young

An excerpt from Manhattan Beach Project
http://www.manhattanbeachproject.com/Scientific-Roadmap-to-Cure-Aging.htm

forever-young

In order to reverse the damages of aging, we most likely only have to mature the following technologies and sciences. Some current technologies are designed to extend your life. Longer-term projects are being developed to transform the elderly into youthful people and to keep them youthful and healthy.

Medical nanobots could end disease, aging in 2 decades

Throughout history doctors have sought to help the human body repair itself. Over the years, many new procedures have been added to the physician’s toolkit – x-rays, anesthesia, antibiotics, surgery, and more recently, stem cells and genetic engineering. For the most part though, doctors still rely on the body’s own trusted healing abilities.

Nearly all sickness, injury, and stress can be traced to cellular malfunction, but physicians have not yet perfected technologies to replace or renew damaged cells. Today, tools do not exist that enable scientists to enter individual cells and make repairs at this molecular level.

People who are considered dead by current legal or medical definitions may not necessarily be dead

Cryopreservation of people or large animals is not reversible with current technology. The stated rationale for cryonics is that people who are considered dead by current legal or medical definitions may not necessarily be dead according to the more stringent information-theoretic definition of death.

It is proposed that cryopreserved people might someday be recovered by using highly advanced technology. Those who believe that revival may someday be possible generally look toward advanced bioengineering, molecular nanotechnology, nanomedicine, or mind uploading as key technologies.

Suspended Animation

Temperature-induced

In June 2005 scientists at the University of Pittsburgh‘s Safar Center for Resuscitation Research announced they had managed to place dogs in suspended animation and bring them back to life, most of them without brain damage, by draining the blood out of the dogs’ bodies and injecting a low temperature solution into their circulatory systems, which in turn keeps the bodies alive in stasis. After three hours of being clinically dead, the dogs’ blood was returned to their circulatory systems, and the animals were revived by delivering an electric shock to their hearts. The heart started pumping the blood around the frozen body, and the dogs were brought back to life.

Death Occurs in Stages

The heart stops, the body convulses, the person starts taking short gasping breaths, and the ears become cold due to the lack of circulation. The blood turns acidic, the larynx loses its cough reflex and a build up of mucous may occur. The passage of breath through this mucous due to spasms will cause a gurgling or rattle-like sound. This specific sound is also known as the “death rattle.” The lungs shut down and the brain also stops functioning. However, if the brain stem is still alive, the body still retains the ability to heal and perform other crucial functions.
