In good news for food lovers, studies threw doubt on the idea that restricting calories to very low levels might
extend life span in humans.
Scientists have known for a long time that caloric restriction
extends life span for yeast, worms, mice and probably primates.
She lives in the security of a walled city on prime water - front property along - side other equally beautiful people
with extended life spans.
The field is also increasingly focusing not just
on extending life span, but extending «health span,» he said.
It came as a surprise to the researchers because severe caloric restriction has also been shown to
extend the life span of many animals.
Researchers first discovered the connection between lean diets and
extended life spans in a 1935 study of calorie - restricted rats.
Bringing your vehicle to an experienced technician for regular maintenance and necessary repairs will help keep your Land Rover running great and it will also
help extend its life span.
This is another method of reducing cancer incidence and
also extending life span by 30 % or so, but this time seemingly through manipulation of the insulin signalling system in a more subtle way than previous growth hormone knockout studies.
«If we could find a way to protect mitochondrial DNA, either with drugs or by using gene therapy to transplant it to the nucleus, it could not
only extend our life spans but prevent many of the diseases we associate with aging as well.»
A study at Harvard University found that alternate - day fasting among mice, «protected mice from strokes, Alzheimer's and Parkinson's disease, and
consistently extended their life spans by 30 percent.»
Exactly how the
drugs extend life span in worms is mysterious, although they seem to stimulate the nematode's neuromuscular system (the neurons that control movement and muscles).
In 1935, the Cornell University nutritionist Clive McCay reported that feeding rats just barely enough to keep them
alive extended their life span by as much as 50 percent.
The researchers point out that the popularity of TNR in the U.S. has been in part due to a goal of maximizing feral cats» quality of life (
e.g. extended life span, vaccinations, assessment for infectious disease) and reducing undesirable behaviors such as aggression and vocalization while still eliminating colonies over time.
«There has been this kind of settled paradigm that caloric restriction
universally extends the life span of animals, [and] some have implied that it also applies to humans,» says study lead author Rajindar Sohal, a pharmacologist at the University of Southern California, Los Angeles.
What was especially «exciting» about this finding, he says, is that these variations were near a neural highway that previous studies have shown helps regulate life span in worms and flies, and that stopping chemical signals from this brain
pathway extends the life span of mice.
Beyond offering further proof that single genes can have dramatic influences on longevity, an idea that drew skepticism just a decade ago, the new finding may help scientists explain how severely reducing calorie
intake extends life span in a variety of animals (SN: 11/25/00, p. 341: Low - cal diet may reduce cancer in monkeys).
Bacteria extended life span only if the fruit flies were exposed within 4 days of hatching; in fact, removing bacteria with antibiotics made old fruit flies live 10 % longer.
Researchers have shown that a class of antiseizure drugs
markedly extends the life span of the roundworm Caenorhabditis elegans — a finding that may have implications for higher organisms.
Experiments with mice, fruit flies, yeast cells, and tiny worms called nematodes, or roundworms, have pointed to environmental modifications that can
extend life span dramatically.
Publication T. Wilhelm et al., Neuronal inhibition of the autophagy nucleation
complex extends life span in post-reproductive C. elegans, Genes & Development, 7 September 2017, DOI: 10.1101 / gad.301648.117
In a recent study of fruit flies (commonly used as human stand - ins), a key antioxidant in
apples extended the life span of the flies by 10 percent and preserved their ability to function well late in life.
Thus, with age there are many things that can decline, so supplementation with various nutrients and supplements, and CR and adequate exercise and sleep may help
extend your life span somewhat.
By neutralising the free radicals that are so prone to wreaking havoc on your cells, antioxidants are great
at extending your life span.
Barrier film - a flexible transparent film to cover materials involved in organic electronics, protecting them from exposure to oxygen and water vapour, allowing them to remain non-rigid and
extending their life span considerably.
A study at Harvard University found that alternate - day fasting among mice, «protected mice from strokes, Alzheimer's and Parkinson's disease, and
consistently extended their life spans by 30 percent.»
