Despite the subsequent lack of maintenance, many parts of the walls survived and are still standing today.
Despite early animal models implicating the non-telomeric role of DKC1 mutations in disease, a more recent mouse model that directly disturbs telomere maintenance displays many of the features of DC, directly implicating telomerase and telomere maintenance in development of the phenotype.
It has had little money for training and maintenance, and many of its submarines and ships are rusting at their piers.
Some of the protesters were maintenance workers (many of them former convicts), who work for the city of Palermo, which no longer has the money to pay them.
"Because of inertia and limited maintenance time, many of the stage systems are beyond their expected life span and close to failure," it said.
Along with the change of operator and stock, the Norwegian National Rail Administration, who owns the stations and tracks, did an overhaul of maintenance on many of the stations, in particular removing years of vandalism.
In zebrafish, piRNAs have been implicated in germ cell maintenance and many of them were mapped to transposons, suggesting that they have a role in silencing repetitive elements in vertebrates [ 11].
Iron is responsible for the maintenance of many of our body's functions.
Mcl-1 is critically required for the development and maintenance of many cells of the hematopoietic system and it is sufficient to take away Mcl-1 in mature lymphocytes to induce apoptosis.
The three sequence Variable Regions of the 10,000 bp unit, consisting of approximately 1000 bp each have mutations that may be viewed as a trial and error processes with a strong partiality to maintaining a very high A + T content and formation and maintenance of many copies of the TATAATATA motif.
