Most of the tissues ordspråk

Most of the tissues that age ... that we're interested in -- the brain, the heart, the muscle, the kidney, etc. -- those cells never divide at all and they never replicate their nuclear DNA so their telomeres can't get shorter and, therefore, that couldn't affect their longevity,

In regular cells, like in bone and blood, the cells divide. But brain cells do not normally divide. The great majority will not divide. The neurons you're born with are pretty much what you have at end of life.

Normal levels of telomerase didn't lengthen short telomeres in our mice, so the longer the telomeres are to start with, the longer transplanted stem cells will be able to divide and the more likely the transplant is to succeed.

After we controlled for everything we could think of related to longevity - such as health status, heart disease, stroke, diabetes, high blood pressure, physical functioning, kidney function, cognitive function, pulmonary function, peripheral vascular disease, age, education, race and sex - the WMG and VG in combination became a powerful predictor of longevity.

We found they could be induced to mature into nerve cells, hair follicles, muscle cells and gut endoderm cells. And when cultured in lab dishes, the cells differentiated, or matured, into the three major basic types of cell.

It turns out that an adult muscle cell's capacity to repair damaged muscle is directly related to where it comes from, and this has implications for the potential use of SP cells in repairing muscle in muscular dystrophy patients.

Brain cells create ideas. Stress kills brain cells. Stress is not a good idea.

We speculate that our brains can compensate for up to a 60 percent loss of pre-Boetzinger cells, but the cumulative deficit of these brain cells eventually disrupts our breathing during sleep. There's no biological reason for the body to maintain these cells beyond the average lifespan, and so they do not replenish as we age,

The weight loss comes primarily from water, but then you shift into mobilizing fat that's in your storage. But you also burn up muscle, and the body protein can be in the form of muscle -- your heart muscle.

Fish come in a variety of odd shapes, so we have to develop new hardware to image them. Engineer Larry May at our center is building special coils for fish. We are also working on new ways of collecting data, since fish tissue can be very different from the tissues we typically image. By tailoring the technology we will further optimize our use of MRI, whether we're imaging cardiac muscle, brain tissue, cartilage or fish.

Stem cells with DNA matching with patient tissues regarding the 2005 paper were not found. And it is the panel's judgment that Professor Hwang 's team does not have the scientific data to prove that they (patient-specific stem cells) were made.

Our goals were to address the following, ... Does ascorbate in pharmacologic concentrations kill cancer cells, but not normal cells, using conditions that mimic IV use and a clinically relevant time course? Is action dependent on extracellular ascorbate, intracellular ascorbate, or both? If effective, what are the mechanisms? Can ascorbate be delivered to tissues without harm? Are there implications for other diseases?
