      From: treon3verdery@gmail.com              Longevity technology: Scientists have already found the differences between       the longest and shortest lived bats. They found 2089 gene variants between the       two. Noting about 1000 of those genes are likely shared with humans (Homo       sapiens and branch        species), those thousand genes can be installed with gene therapy into mice,       at 21 groups of 49 genes each, and 11 mice per group to get a p value on       longevization effects. That is just 232 mice. It may be possible to do this       with even fewer mice using a        fractional matrix design procedure. After that, two to four rounds of       different simultaneous potential longevity gene concentrating admixtures can       be accomplished. Biomarkers of aging could be used to determine reduced aging       prior to actual determination        of 98th percentile longevity. Using biomarkers allows faster rounds of       selection and remixing. Another completely different approach is to use the       high N outdoor mouse dorm, combined with crispr/cas9 to generate mice with       just 11 long lived bat genes per        mouse among those genes that are shared with humans. The outdoor mouse dorm       mice then have sex and babies. As these generations of mice reach 6-18 months       they may have readable aging biomarkers, and the least aging mice grouped       together to have babies        again. Those progeny mice are then screened for most minimal aging at       biomarkers of aging, making a round. This can also be done with bowhead whale       genes, and 400 year lifespan tortoises and 400 year lifespan quahog clam       genes. The abstract of comparing        bat longevity genetics says, "Bats are the longest-lived mammals given their       body size with majority of species exhibiting exceptional longevity. However,       there are some short-lived species that do not exhibit extended lifespans.       Here we conducted a        comparative genomic and transcriptomic study on long-lived Myotis myotis       (maximum lifespan = 37.1 years) and short-lived Molossus molossus (maximum       lifespan = 5.6 years) to ascertain the genetic difference underlying their       divergent longevities. Genome-       wide selection tests on 12,467 single-copy genes between M. myotis and M.       molossus revealed only three genes (CCDC175, FATE1 and MLKL) that exhibited       significant positive selection. Although 97.96% of 12,467 genes underwent       purifying selection, we        observed a significant heterogeneity in their expression patterns. Using a       linear mixed model, we obtained expression of 2,086 genes that may truly       represent the genetic difference between M. myotis and M. molossus. Expression       analysis indicated that        long-lived M. myotis exhibited a transcriptomic profile of enhanced DNA repair       and autophagy pathways, compared to M. molossus. Further investigation of the       longevity-associated genes suggested that long-lived M. myotis have naturally       evolved a        diminished anti-longevity transcriptomic profile. Together with observations       from other long-lived species, our results suggest that heightened DNA repair       and autophagy activity may represent a universal mechanism to achieve       longevity in long-lived        mammals." Another way to gain greater mouse and human (Homo sapiens and branch       species) longevity is to consider the M, Myotis bat as normal, and the shorter       lived bat as having deleterious genes, a third bat midway between the two       could also be        characterized. This way it is possible to search for and likely find things       the M. Molossus produces that actually decrease lifespan (interleukins,       beneficial network or cascade "slowdown" physiochemicals, proteins like Brd2).       The researchers method        could be applied to long and short lived tortoises as well as quahog clams and       the clams' shortest lived clam relatives.              Well baby genetics, rounds of mouse and marmoset genetics, epigenetic drug       benefits humans              Persons at the 90th percentile of intelligence and above who have zero family       history of birth defects may have a traceable genetics of being absent birth       defects that can be made into RNA drugs and gene therapies that after testing       at mice can be tested        by volunteers who are planning a pregnancy.              Diacetyl melatonin night be measured as being especially longevizing at the       brain, while melatonin palmitate could especially benefit lipid rich regions,       and the free base of melatonin can reach the other regions, it could be       especially longevizing to        take all three together,              Longevity technology, the least change to an amino acid sequence that creates       quaternary protein structure could be used at longevity producing proteins to       make new varieties of those proteins likely with unique effects, possibly       encouraging longevity,        similarly at longevity proteins the least amino acid sequence change that       removes quaternary structure could also make improved protein longevity drugs,       a variety of protein structures for any particular near identical amino acid       sequences could be        screened at mice to see which is the most active at longevization form to turn       into a human protein drug or gene therapy tested by volunteers.                     Precluding pattern recruitment at people under 18 or older with amygdala size       reduction that is absent effect on cognitive g, is genetics that preclude       acting in anger and is beneficial.                     [continued in next message]              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
